In addition, all statements other than statements of historical facts that address activities, events, or developments we expect, believe, or anticipate will or may occur in the future, and other such matters, are forward-looking statements.

 Future events and actual results could differ materially from those set forth in, contemplated or suggested by, or underlying the forward-looking statements. There can be no assurances that results described in forward-looking statements will be achieved, and actual results could differ materially from those suggested by the forward-looking statements. The forward-looking statements included herein are based on current expectations that involve a number of risks and uncertainties, including, among other things, volatility throughout the global economy and the related impacts to the businesses of our suppliers and customers, such as customer demand fluctuations, supply chain constraints and inflationary pressures, as well as difficulties in resolving our continuing financial condition and ability to obtain additional capital to meet our financial obligations, including, without limitation, difficulties in obtaining adequate capital resources to fund our operations. Other important factors that could cause our actual results to differ materially from those in our forward-looking statements include those discussed in the section entitled "Risk Factors" in this Form 10-K and in our subsequent filings with the U.S. Securities and Exchange Commission (the "SEC"). These forward-looking statements are also based on certain additional assumptions, including, but not limited to, that we will retain key management personnel; we will be successful in the commercialization of our products; we will obtain sufficient capital to commercialize our products and continue development of complementary products; we will be successful in obtaining marketing authorization for our products from the FDA and other regulatory agencies and governing bodies; we will be able to protect our intellectual property; our ability to respond effectively to technological change; our ability to accurately anticipate market demand for our products; and that there will be no material adverse change in our operations or business and general market and industry conditions. Assumptions relating to the foregoing involve judgments with respect to, among other things, future economic, competitive and market conditions and future business decisions, all of which are difficult or impossible to predict accurately and many of which are beyond our control.

 Although we believe that the assumptions underlying the forward-looking statements are reasonable, any of

 the assumptions could prove inaccurate and, therefore, there can be no assurance that the results contemplated in forward-looking statements will be realized. Any forward-looking statements made by us in this Form 10-K speak only as of the date on which they are made. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

 Item 1. Business

 Overview

 Accelerate Diagnostics, Inc. ("Accelerate") is an in vitro diagnostics company dedicated to providing solutions that improve patient outcomes and lower healthcare costs through the rapid diagnosis of serious infections. Microbiology laboratories need new tools to address what the U.S. Centers for Disease Control and Prevention (the "CDC") calls one of the most serious healthcare threats of our time, antibiotic resistance. A significant contributing factor to the rise of resistance is the overuse and misuse of antibiotics, which is exacerbated by a lack of timely diagnostic results. The delay of identification and antibiotic susceptibility results is often due to the reliance by microbiology laboratories on traditional culture-based tests that often take two to three days to complete. Our technology platform is intended to address these challenges by delivering significantly faster testing of infectious pathogens in various patient sample types.

 Our Products

 Accelerate Pheno

 Our first system to address these challenges is the Accelerate Pheno system. The Accelerate PhenoTest BC Kit, which is the first test kit for the system, is indicated as an aid, in conjunction with other clinical and laboratory findings, in the diagnosis of bacteremia and fungemia, both life-threatening conditions with high morbidity and mortality risk. The device provides identification ("ID") results followed by antibiotic susceptibility testing ("AST") for certain pathogenic bacteria commonly associated with or causing bacteremia. This test kit uses genotypic technology to identify infectious pathogens and phenotypic technology to conduct AST, which determines whether live bacterial cells are resistant or susceptible to a particular antimicrobial. This information can be used by physicians to rapidly modify antibiotic therapy to lessen adverse events, improve clinical outcomes and help preserve the useful life of antibiotics.

 In June 2015, we declared our conformity to the European In Vitro Diagnostic Directive 98/79/EC and applied a CE mark to the Accelerate Pheno system and the Accelerate PhenoTest BC Kit for in vitro diagnostic use. On February 23, 2017, the FDA granted our de novo classification request to market the first version of our Accelerate Pheno system and Accelerate PhenoTest BC Kit.

 In 2017, we began selling the Accelerate Pheno system in hospitals in the United States, Europe and the Middle East. Consistent with our "razor" / "razor-blade" business model, revenues to date have principally been generated from the sale or leasing of the instruments, and the sale of single use consumable test kits.

 In August 2022, we entered into a sales and marketing agreement (the "Sales and Marketing Agreement") with BD. We entered into the Sales and Marketing Agreement in order to leverage BD's expansive global sales team, benefit from natural synergies between BD's existing products and our products, and reduce our sales and marketing expenses.

 Accelerate Arc

 In 2022, we announced the launch and commercialization of the Accelerate Arc system and BC Kit ("Accelerate Arc Products"). This instrument and associated one-time-use test kit automates the clean-up and concentration of microbial cells from positive blood culture samples. In June 2022 we received CE In Vitro Diagnostic Regulation (IVDR) registration for use in Europe.

 In September 2024, we received FDA approval for our Accelerate Arc Products in the United States as a 510(k) IVD Class II Device.

 A technology receiving wide attention is mass spectrometry, and particularly the matrix-assisted laser desorption ionization time of flight version ("MALDI-TOF"). These systems build an empiric database from protein spectra acquired from many thousands of purified bacterial and fungal strains. They require a pure strain isolate for analysis and enrichment culturing to produce enough material to analyze.

 MALDI-TOF systems have a major advantage over other methods in identifying a very broad range of organisms. Cost of ownership is also substantially below that of older molecular methods, although the requirement for extensive organism enrichment and purification, as well as the inability to quantify live organisms or distinguish samples derived from viable organisms, substantially limits this technology from time-critical decision support. Also, as with the older molecular methods, MALDI-TOF systems cannot identify major drug resistance expression and face the same fundamental biological barriers as gene detection.

 In November 2023, we announced a collaboration and quality agreement with Bruker, the provider of the MALDI Biotyper MALDI-TOF system for microbial identification, which has agreements with a number of companies for distribution, including BD, Danaher Corporation's subsidiary Beckman Coulter, Thermo Fisher Scientific's subsidiary TREK Diagnostics Systems, Inc. ("TREK") and Siemens. This agreement allows us to partner with Bruker to validate the use of our Accelerate Arc system with Bruker's MALDI Biotyper system for subsequent registration in both the U.S. and Europe, Middle East and Africa ("EMEA") markets.

 Accelerate WAVE

 The Accelerate WAVETM system, currently in clinical trials, performs AST directly from positive blood culture ("PBC") bottles and bacterial isolate colonies ("Isolates") to report minimum inhibitory concentrations ("MICs") with a goal of delivering results within 4.5 hours, on average. The fully automated system is based on the principle of digital holographic microscopy, which allows for simultaneous volumetric imaging of a sample suspension at a high spatial resolution, enabling direct observation of phenotypic responses of individual bacterial cells in relatively short time periods versus more traditional AST methods. The Accelerate WAVE system uses a time series of holograms to provide microbial quantitation under antimicrobial stress, enabling rapid determination of minimum inhibitory concentration. Additionally, Accelerate WAVE holograms provide morphological information at the level of individual cells. For some bug-drug combinations, morphology is a leading indicator of future MIC.

 A key differentiator of the Accelerate WAVE system to current on-market and emerging AST competitors is the system's ability to process PBC as well as Isolates for AST diagnostic results. Our initial launch of menu items is expected to include a PBC assay that can be run on the Accelerate WAVE system. This is expected to be followed by development of an Isolate assay. We believe the ability to process Isolates with the Accelerate WAVE system would expand our addressable market today with our Accelerate Pheno system and Accelerate Arc Products with PBC samples to include a much larger sample volumes segment, Isolates, within the microbiology testing market. Based on our on-market experience with our Accelerate Pheno system, we anticipate seeing significant workflow benefits to microbiology labs by offering consolidated PBC and Isolate susceptibility testing on a single, rapid, AST diagnostic. Further, recent voice-of-customer interviews highlight the value that Accelerate WAVE brings to the global marketplace with a high percentage of interviewed customers expressing interest in evaluating the Accelerate WAVE system once available. The Accelerate WAVE system AST modules will be able to test five PBC assays or ten Isolated Colony assays per module and can scale to have five modules per system, which we believe will address the vast majority of microbiology lab volumes and workflows. Additionally, the cost to produce Accelerate WAVE assays is expected to be significantly lower than our standard costing for the Accelerate PhenoTest BC Kit, which could improve the Company's margin profile as we seek FDA regulatory clearance for the Accelerate WAVE system and assays.

 Our Market and Strategy

 Clinical Need

 Antimicrobial resistance is a major contributing factor to the significant impact sepsis is posing to healthcare, costing the U.S. an estimated $62.0 billion per year in healthcare and productivity costs. Increasing infection rates and misuse of antibiotics results in serious treatment complications. Recent studies have shown that the number of hospital-acquired infections in the United States ranges from 214,700 to 1.4 million per year, contributing to an estimated 75,000 deaths per year. According to the CDC, at least 2.8 million people get an antibiotic-resistant infection each year in the United States. Moreover, inappropriate antibiotic use is widespread. Of the approximately 35 million patients admitted to U.S. hospitals each year, 56% are put on empiric antibiotic

 therapy, of which more than half are on inappropriate or unnecessary antibiotics.

 AST testing is routinely performed by clinical microbiology laboratories to determine which antibiotics will be effective and which will be ineffective for treating a particular patient's infections. Accordingly, AST is ideally designed to address this challenge but previous post-culture methods for obtaining AST results took 2-3 days to deliver. Studies have shown that even a modest decrease in the time it takes to deliver an AST result correlates to reduced length and cost of hospital stay per patient. One such study comparing the Accelerate Pheno system to the standard of care methodology, showed that time to definitive therapy improved from 32.6 to 10.5 hours, the total duration of therapy shortened from 14.2 to 9.5 days and the mean hospital length of stay was shortened from 7.9 to 5.3 days1. Based on our analysis, we estimate that the Accelerate Pheno system is capable of delivering clinically-actionable results in approximately 19 hours from the time a blood sample is received by the laboratory, while current solutions often require 2-3 days to deliver these results. Studies have established that results from the Accelerate Pheno system are available, on average, 29 hours earlier with respect to ID and 54 hours earlier with respect to AST, than traditional methods.

 Rapid AST is particularly important in improving sepsis patient outcomes. Sepsis is responsible for approximately 270,000 deaths, inclusive of hospital-acquired infection deaths, in the United States annually, which is one in three U.S. hospital patient deaths. Optimizing antibiotics within the first 24 hours of hospitalization is critical. It is estimated that 80% of sepsis deaths could be prevented with rapid diagnosis and treatment. By providing clinically-actionable results in hours instead of days, we believe that the Accelerate Pheno system can play a significant role in allowing physicians to provide timely, effective therapy to sepsis patients.

 Market Opportunity

 Across North America, Europe and Asia Pacific geographies, we estimate there are over 300 million ID and AST tests completed annually across various sample types. We estimate that of these tests, our current test kit, the Accelerate PhenoTest BC Kit, has the potential to address the over four million positive blood culture samples tested each year in North America and Europe.

 In addition, there is a substantial existing installed base of legacy automated AST systems that perform AST from Isolates. Principally, these systems are the bioMerieux Vitek 2, Danaher Corporation ("Danaher") Microscan system, and BD PhoenixTM. These competitors' AST products require purified bacterial strains or Isolates for analysis, which require at least overnight culturing of a clinical specimen to produce enough organisms to test. This installed base represents an attractive opportunity to both potentially complement and replace existing laboratory workflows with the Accelerate Pheno system and our next generation Accelerate WAVE system rapid testing solutions.

 Certain government initiatives are complementary to the Accelerate Pheno system. For example, effective October 1, 2008, hospitals no longer receive additional payment for cases in which a hospital-acquired condition, as determined by the Centers for Medicare and Medicaid Services, the federal agency responsible for administering the Medicare program ("CMS"), occurred but was not present on admission, thereby incentivizing providers to enhance infection-management protocols. Similarly, effective October 1, 2012, CMS implemented the Hospital Readmissions Reduction Program, which reduces payments to hospitals for excess readmissions. Similarly, on March 27, 2015, the White House released the National Action Plan for Combating Antibiotic-Resistant Bacteria, which directly and indirectly promotes rapid susceptibility testing. The plan identified several milestones to accomplish this goal, such as calling on the National Institutes of Health to fund new projects and provide prizes aimed at the development of rapid diagnostic tests that characterize antibiotic susceptibility and improve antibiotic stewardship; mandating implementation of antibiotic stewardship programs by all hospitals participating in Medicare and Medicaid; and calling on the FDA and CMS to evaluate new regulatory pathways to promote development and adoption of innovative infectious disease diagnostics. In October 2020, the Federal Task Force on Combating Antibiotic-Resistant Bacteria released a new National Action Plan for 2020-2025, which establishes new objectives and targets. This plan prioritizes infection prevention and control to slow the spread of resistant infections and reduce the need for antibiotic use. This plan also focuses on collecting and using data to better understand where resistance is occurring, support the development of new diagnostics and treatment options, and advance international coordination.

 Key Advantages of our Technology

 The Accelerate Pheno system is the Company's first in vitro diagnostic platform and is intended for the ID and AST of pathogens most commonly associated with serious or health care-associated infections, including Gram-positive and Gram-negative organisms. The system leverages long-accepted bacteriological testing principles enhanced by proprietary technology and automation enabling the analysis of live microbial cells. It detects and identifies pathogens directly from a single patient sample followed by antibiotic susceptibility testing based on the ID results. Antimicrobial susceptibility is determined by morphokinetic cellular analysis ("MCA"), a process that evaluates the change of individual cells and microcolonies in response to a range of antibiotics over time. The system's combined technologies and automation dramatically reduce the need for time-consuming traditional bacterial culturing, thus eliminating the major source of delay with current testing methods. ID results are typically available within 90 minutes of presenting the patient sample to the system, and susceptibility results, including MICs, are available about five hours after ID results. In the case of the Accelerate PhenoTest BC Kit for positive blood culture samples, a blood culture screening step is required, which we estimate takes an average of approximately 12 hours to complete before the sample is introduced to the Accelerate Pheno system. This combined turnaround time is a significant improvement over the multiple days currently required to obtain AST results, with MIC details, using conventional testing methods.

 The Accelerate Pheno system features walk-away automation and consists of a fixed instrument and proprietary single-use test kit. The instrument consists of module(s) connected to a single analysis computer, which allows hospitals to acquire various numbers of modules to address their particular test volume. In order to run a patient sample on the Accelerate Pheno system a laboratory technician would pipette the patient sample into our system, insert the Accelerate PhenoTest BC Kit, and initiate the run. In the case of our initial test, a positive blood culture sample is introduced to the system by pipetting directly from the blood culture bottle into our Accelerate PhenoTest BC Kit.

 The Accelerate Pheno system is the result of over a decade of technological development and several years of instrument design and engineering. The system is comprised of custom-engineered functional components, including a robotic pipettor for fluidic manipulation, an optical system with both dark-field and fluorescent illumination, and an imaging system. These sensor components, among others, are used in the four processes that follow, each of which is a crucial component in delivering the rapid ID and AST results.

 These processes include:

 • Automated specimen preparation. The initial step in the process is the automated purification of samples through an on-board and proprietary process to separate live organisms from sample debris.
 • Live-cell immobilization. Following preparation, the purified sample is moved to the imaging cassette where pathogens are immobilized onto the cassette surface such that they can be imaged and analyzed in a stationary position during the ID and AST testing.
 • ID testing via fluorescent in situ hybridization (FISH). The now immobilized cells are tested with our proprietary FISH probes to enable identification. Because the genetic sequences of bacteria are distinctive, the binding of fluorescently labeled probes indicates the presence of a specific target sequence of RNA associated with a single or group of bacterial species or yeasts. When the probe finds a targeted sequence, it binds to it—generating a fluorescent signal—which is visible by the imaging system on the Accelerate Pheno system. Positive fluorescent signals from more than one target probe indicate polymicrobial samples and a universal bacterial stain discriminates target from non-target bacteria or fungi. The ID result is presented on the Accelerate Pheno system's graphic user interface in approximately 90 minutes from the introduction of the sample into the Accelerate Pheno system.
 • Susceptibility testing via live-cell optical analysis. With the ID of the pathogen known, the system's software determines the antibiotic panel to be used for susceptibility testing. These antibiotics, growth media, and additional patient sample are introduced to additional channels on the optical cassette. Finally, our proprietary imaging platform and algorithms determine the minimum inhibitory concentration of the bacteria by observing which antibiotics arrested live cell growth and led to cell death and which antibiotics were ineffective in ceasing live cell growth. The susceptibility test result is presented approximately five hours after the conclusion of the ID test.

 The Accelerate Pheno system has been the subject of dozens of scientific posters and studies. Recent studies and associated publications have covered subjects including time savings, performance, opportunity rates

 for clinical interventions, and clinical outcomes including length of stay. Published study abstracts and links to full papers are available on our website at  None of the information contained on our website is part of this report or incorporated in this report by reference.

 While we will continue to seek ways to improve the utility of our existing products, the primary focus of our current research and development efforts is our next generation AST platform, the Accelerate WAVE system, which is being developed with the goal to have lower cost, higher throughput, and the capability to test a broader set of sample types when compared to our Accelerate Pheno system.

 Commercialization of our Products

 The target customers for our products are hospital microbiology laboratories that perform ID and AST. In August 2022, the Company entered into the Sales and Marketing Agreement with BD pursuant to which BD is performing certain sales, tactical marketing, technical service call forwarding, order preparation, research and development support and/or regulatory activities on the Company's behalf as its worldwide exclusive sales agent for certain of the Company's products, including the Accelerate Pheno system and Accelerate Arc Products. An existing team of the Company's sales and service specialists partner with BD personnel in the United States and select international countries to market, sell and support the Accelerate Pheno system and Accelerate Arc Products, as applicable.

 The Sales and Marketing Agreement also grants to BD certain other rights to certain of the Company's future products, including a right of first negotiation to be the exclusive sales agent to commercialize the Company's next generation rapid AST system, the Accelerate WAVE system. These rights to negotiate a subsequent agreement will be triggered if the Company proposes to license its next generation rapid AST system or sell its rights to such system, or if the Company and BD mutually agree that the related clinical data is ready to be submitted to the FDA for 510(k) clearance. In accordance with the BD Agreement, the terms of such subsequent agreement would have to be negotiated by the parties.

 The Sales and Marketing Agreement was entered into to allow the Company to reduce expenses through a reduction of internal sales and marketing personnel. Under this agreement, the Company will pay BD a commission based on the level of revenue realized on a quarterly basis and BD will pay the Company a fee over the duration of the agreement based on certain criteria.

 Our business, while not seasonal, is influenced by the timing of hospital budget and tender approval cycles which vary by geography. Due to our relatively long sales cycles, order back-logs are not typical, and we manage our inventory based on forecasted future demand for our products.

 For the year ended December 31, 2024, one of the Company's customers represented 12% of the Company's net sales; no other customer accounted for more than 10% of the Company's net sales.

 Competition

 The leading companies with automated microbiological testing products include BD, bioMerieux, Danaher and TREK. These companies provide products for the broad-based culturing and analysis of a wide variety of bacteria. These competitors' AST products require purified bacterial strains or Isolates for analysis, which require at least overnight culturing of a sample to produce enough organisms to test. We believe these standard culturing methods, including enrichment growth and colony isolation, cannot achieve the speed that the Accelerate Pheno system provides. These companies and other competitors, such as T2 Biosystems have automated bacterial ID products which provide a component of the clinical diagnostics solution but lack rapid AST functionality.

 Potential competitors for rapid AST have made announcements at various trade shows and in press releases, including, but not limited to: Quantamatrix, Q-Linea, Specific Diagnostics, Lifescale, and Gradientech. While we do not have visibility into all of these companies' respective stages of development, it has been reported that several of these competitors have obtained FDA marketing authorization for their product in the United States. In 2022, bioMerieux acquired Specific Diagnostics for over $400.0 million. We believe this acquisition reflects both the industry leader's recognition of the importance of rapid AST testing and enhanced competition.

 The clinical microbiology industry is subject to rapid technological changes, and new products are frequently introduced for rapid bacterial ID using genes or other molecular markers. Numerous acquisitions,

 licenses, and distribution arrangements have been announced over the last few years for such products. However, we do not believe that any of these technologies offers the advantages afforded by the Accelerate Pheno system. For example, gene detection can be highly sensitive and specific for the ID of pathogens, but very few antibiotic resistance mechanisms are simple enough to accurately guide drug selection. Even in those rare instances where there is a direct relationship between a gene and effective antimicrobial resistance, such as particular Methicillin-Resistant Staphylococcus aureus (MRSA) strains, leading literature has reported novel mutations that escape detection by recently commercialized tests.

 In addition to existing and emerging companies, there are manual methods which could be validated by individual hospitals to deliver rapid ID and susceptibility results. See "Risk Factors-Risks Related to Our Business and Strategy-Our industry is highly competitive, and we may not be successful in competing with our competitors. We currently face competition from new and established competitors and expect to face competition from others in the future, including those with new products, technologies or techniques" for additional information.

 Government Regulation

 Our products under development and our operations are subject to significant government regulation. In the United States, our products are regulated as medical devices by the FDA and other federal, state, and local regulatory authorities.

 FDA Regulation of Medical Devices

 The FDA and other U.S. and foreign governmental agencies regulate, with respect to medical devices:

 • design, development, manufacturing, and storage;
 • testing, content, and language of instructions for use and storage;
 • labeling;
 • pre-clinical testing and clinical trials;
 • product safety;
 • advertising, promotion, marketing, sales, and distribution;
 • pre-market clearance and approval;
 • record-keeping procedures;
 • advertising and promotion;
 • recalls and corrective field actions;
 • post-market reporting, including reporting of deaths, serious injuries, and malfunctions that, if they were to recur, could lead to death or serious injury;
 • post-market studies and surveillance; and
 • product import and export.

 In the United States, numerous laws and regulations govern all the processes by which medical devices are brought to market and marketed. These include the Federal Food, Drug and Cosmetic Act (the "FDCA") and the FDA's regulations implementing the law codifying the FDCA.

 FDA Pre-market Clearance and Approval Requirements

 Each medical device we seek to commercially distribute in the United States must first receive 510(k) clearance, approval of a reclassification petition or de novo classification request, or pre-market approval from the FDA, unless specifically exempted by the FDA. The FDA categorizes medical devices into one of three classes - Class I, II, or III - based on their risks and the regulatory controls necessary to provide a reasonable assurance of safety and effectiveness. Class I devices generally pose the lowest risk to the patient and/or user and Class III devices pose the highest risk. Regulatory control increases from Class I to Class III. The device classification regulation defines the regulatory requirements for a general device type. Generally, in order to market or commercially distribute a Class I, II, and III device intended for human use in the United States, for which a premarket approval ("PMA") is not required, one must submit a 510(k) to FDA unless, as noted, the device is exempt from the 510(k) pre-market notification requirements of the FDCA. Per the FDA, generally, most Class I devices are exempt from Premarket Notification 510(k); most Class II devices require Premarket Notification 510(k); and most Class III devices require a PMA.

 510(k) Clearance Process

 To obtain 510(k) clearance, we must submit a pre-market notification to the FDA demonstrating that the proposed device is substantially equivalent to a device that has previously obtained 510(k) clearance, a device that has been classified into Class I or II, or a device that was legally marketed before May 28, 1976 and that is not yet subject to an FDA order requiring pre-market approval. In rare cases, Class III devices may be cleared through the 510(k) process. The FDA has committed to review most 510(k) decisions within 90 days, but the review clock may be stopped due to requests for additional information. A decision may take significantly longer, and clearance is never assured. Although many 510(k) pre-market notifications are cleared without clinical data, in some cases, the FDA requires clinical data to support substantial equivalence. In reviewing a pre-market notification submission, the FDA may request additional information, including clinical data, which may significantly prolong the review process.

 After a device receives 510(k) clearance, any subsequent modification of the device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, requires a new 510(k) clearance or, in some cases, approval of a PMA. The FDA requires each manufacturer to make this determination initially, but the FDA may review any such decision and may disagree with a manufacturer's determination. If the FDA disagrees with a manufacturer's determination, the FDA may require the manufacturer to cease marketing and/or recall the modified device until 510(k) clearance or approval of a PMA is obtained. Under these circumstances, the FDA may also subject a manufacturer to enforcement action and sanctions, including those described below. In addition, the FDA is currently evaluating the 510(k) process and may make substantial changes to regulatory requirements, including changes that could affect which devices are eligible for 510(k) clearance, the FDA's ability to rescind 510(k) clearances, and additional requirements that may significantly impact the 510(k) review process.

 Pre-market Approval Process

 A PMA generally must be submitted if the medical device is in Class III or cannot be cleared through the 510(k) process. A PMA must be supported by extensive technical, preclinical, clinical, manufacturing, and labeling data to demonstrate to the FDA's satisfaction the safety and effectiveness of the device.

 After a PMA is submitted and filed, the FDA begins an in-depth review of the submitted information. During this review, the FDA may request additional information or clarification of information already provided. Also during the review period, an advisory panel of experts from outside the FDA may be convened to review and evaluate the application and provide recommendations to the FDA as to the approvability of the device. In addition, the FDA will conduct a pre-approval inspection of the manufacturing facility to ensure compliance with Quality System Regulations ("QSR"), which imposes elaborate development, testing, control, documentation and other quality assurance requirements on the design and manufacturing process. The FDA has committed to review most PMAs within 180 days where an advisory panel is not required and within 320 days where an advisory panel is required, but the review clock may be stopped due to requests for additional information. A decision may take significantly longer, and approval is never assured. The FDA may approve a PMA with post-approval conditions intended to ensure the safety and effectiveness of the device including restrictions on labeling, promotion, sale, and distribution and collection of safety data. Failure to comply with the conditions of approval can result in enforcement action and sanctions, including those described below. New PMAs or PMA supplements are required for significant modifications to the manufacturing process, labeling of the product, or design of a device that is approved through the PMA process. PMA supplements often require submission of the same type of information as an original PMA, except that the supplement is limited to information needed to support any changes from the device covered by the original PMA and may not require as extensive clinical data or the convening of an advisory panel.

 De novo Classification Process

 Medical device types that the FDA has not previously classified as Class I, II, or III are automatically classified into Class III regardless of the level of risk they pose. The Food and Drug Administration Modernization Act of 1997 established a new route to market for low-to-moderate risk medical devices that are automatically placed into Class III due to the absence of a predicate device, called the "Request for Evaluation of Automatic Class III Designation," or the de novo classification procedure. This procedure allows a manufacturer whose novel device is automatically classified into Class III to request down-classification of its medical device into Class I or Class II on the basis that the device presents low or moderate risk, rather than requiring the submission and approval of a PMA. Prior to the enactment of the Food and Drug Administration Safety and Innovation Act ("FDASIA") in July 2012, a medical device could only be eligible for de novo classification if the manufacturer first submitted a 510(k)

 pre-market notification and received a determination from the FDA that the device was not substantially equivalent to a predicate device. FDASIA streamlined the de novo classification pathway by permitting manufacturers to also request de novo classification directly without first submitting a 510(k) pre-market notification to the FDA and receiving a not substantially equivalent determination. Under FDASIA, the FDA is required to classify the device within 120 days following receipt of such a direct de novo request; however, this time period can be extended if questions and/or requests for additional information are asked of the applicant. If the manufacturer seeks classification into Class II, the manufacturer should include a draft proposal for special controls that are necessary to provide a reasonable assurance of the safety and effectiveness of the medical device. In addition, the FDA may reject a de novo request if the FDA identifies a legally marketed predicate device that would be appropriate for a 510(k), determines that the device is not low-to-moderate risk, or determines that general controls would be inadequate to control the risks and special controls cannot be developed.

 On February 23, 2017, the FDA granted our de novo request to market the Accelerate Pheno system and Accelerate PhenoTest BC Kit as a Class II medical device.

 Clinical Trials

 Clinical trial data is typically required to support a PMA and is sometimes required for a 510(k) pre-market notification. Initiation of a clinical trial generally requires submission of an application for an Investigational Device Exemption (an "IDE") to the FDA. The IDE application must be supported by appropriate data, such as animal and laboratory testing results, showing that it is safe to test the device in humans and that the investigational protocol is scientifically sound. The IDE application must be approved in advance by the FDA for a specified number of patients, unless the product is deemed a non-significant risk device and eligible for abbreviated IDE requirements. Clinical trials for a significant risk device may begin once the IDE application is approved by the FDA as well as the appropriate institutional review boards at the clinical trial sites and the informed consent of the patients participating in the clinical trial is obtained. After a trial begins, the FDA may place it on hold or terminate if it concludes that the clinical subjects are exposed to unacceptable risks. Any trials we conduct must be undertaken in accordance with FDA regulations as well as other federal regulations and state laws concerning human subject protection and privacy, including, but not limited to the Health Insurance Portability and Accountability Act ("HIPAA") Privacy Rule (45 CFR Part 160 and Subparts A and E of Part 164) and the Security Rule (45 CFR Part 160 and Subparts A and C of Part 164). Moreover, the results of a clinical trial may not be sufficient to obtain clearance or approval of the product.

 Clinical trial sponsors may also be subject to the Medicare Secondary Payer laws, which prohibit Medicare from making a payment if payment has been made or can reasonably be expected to be made by other plans, such as liability insurance plans (including self-insurance). Section 111 of the Medicare, Medicaid, and SCHIP Extension Act of 2007 ("MMSEA") established mandatory reporting requirements with respect to Medicare beneficiaries who receive settlements, judgments, awards, or other payment from liability insurance (including self-insurance) plans. When payments are made by sponsors of clinical trials for complications or injuries arising out of the trials, such payments are considered to be payments by liability insurance (including self-insurance) and must be reported. Section III of the MMSEA includes authority for CMS to impose civil monetary penalties against liability insurance (including self-insurance) plans that are determined to be non-compliant with the applicable reporting requirements.

 Pervasive and Continuing Regulation

 After a medical device is placed on the market, numerous FDA regulatory requirements apply, including the following:

 • the QSR, which imposes elaborate development, testing, control, documentation, and other quality assurance requirements on the design and manufacturing process;
 • establishment registration, which requires establishments involved in the production and distribution of medical devices, intended for commercial distribution in the United States, to register with the FDA;
 • medical device listing, which requires manufacturers to list the devices they have in commercial distribution with the FDA;
 • labeling regulations and various statutory provisions, which prohibit false or misleading labeling, as well as the promotion of products for unapproved or "off-label" uses, and impose other restrictions on labeling; and
 • post-market reporting requirements, which require that manufacturers report to the FDA deaths, serious injuries, and malfunctions that, if they were to recur, could lead to death or serious injury, recalls, and corrective field actions.

 In certain cases, advertising is also subject to scrutiny by the Federal Trade Commission ("FTC") in addition to the FDA. The FDA and other agencies actively enforce these and other applicable laws and regulations, accordingly. Failure to comply with applicable requirements may result in enforcement action by the FDA and/or the U.S. Department of Justice ("DOJ"), which may include one or more of the following administrative or judicial sanctions:

 • untitled letters or warning letters;
 • fines, injunctions, and civil penalties;
 • mandatory recall or seizure of our products;
 • administrative detention or banning of our products;
 • operating restrictions, partial suspension, or total shutdown of production;
 • import holds;
 • refusing to approve pending 510(k) notifications;
 • revocation of 510(k) clearance or pre-market approvals previously granted; and
 • criminal prosecution and penalties.

 International Regulation

 Sales of medical devices outside the United States are subject to foreign government regulations, which vary substantially from country to country. In order to market our products in other countries, we must obtain regulatory approvals and comply with extensive safety and quality regulations in other countries. The time required to obtain approval by a foreign country may be longer or shorter than that required for FDA clearance or approval, and the requirements may differ significantly.

 In the European Economic Area ("EEA") which comprises the 27 Member States of the European Union ("EU") plus Liechtenstein, Norway and Iceland, in vitro medical devices are required to conform with the essential requirements of the EU Directive on in vitro diagnostic medical devices (Directive 98/79/EC, as amended). To demonstrate compliance with the essential requirements, the manufacturer must undergo a conformity assessment procedure. The conformity assessment varies according to the type of medical device and its classification. For low-risk devices, the conformity assessment can be carried out internally, but for higher risk devices (self-test devices and those included in List A and B of Annex II of Directive 98/79/EC) it requires the intervention of an accredited EEA notified body. If successful, the conformity assessment concludes with the drawing up by the manufacturer of an EC Declaration of Conformity entitling the manufacturer to affix the CE mark to its products and to sell them throughout the EEA. The EC Declaration of Conformity was received by the Company in 2015 for the Accelerate Pheno system and the Accelerate PhenoTest BC Kit.

 Other Healthcare Laws

 Following the FDA's granting of our de novo request to market the Accelerate Pheno system and Accelerate PhenoTest BC Kit, we commenced active commercialization of the Accelerate Pheno system. Such business activities, including the activities of any third-party distributors that we retain, will be subject to additional healthcare laws and regulations and related enforcement by the federal government as well as the governments of states and foreign jurisdictions where we conduct our business. These laws and regulations include, without limitation, state and federal anti-kickback, fraud and abuse (including state and federal Stark law), false claims, privacy and security, and physician payment transparency laws and regulations. Violations of these laws or regulations can result in criminal or civil sanctions, including substantial fines and, in some cases, exclusion from participation in federal healthcare programs, such as Medicare and Medicaid. The following discussion describes certain federal and state healthcare laws and regulations that may impact our operations and the operations of our customers, but is not intended to be an exhaustive discussion of all potentially applicable federal and state health laws and regulations.

 The U.S. federal Anti-Kickback Statute prohibits any person from knowingly and willfully offering, soliciting, receiving, or providing remuneration, directly or indirectly, overtly or covertly, in cash or in kind, in exchange for or to induce either the referral of an individual for an item or service, or the purchasing, leasing, ordering, or arranging for or recommending the purchase, lease, or order of any good, facility, item, or service for which payment may be made, in whole or in part, under a federal healthcare program, such as the Medicare and Medicaid programs. A person need not have actual knowledge of the Anti-Kickback Statute or specific intent in order to commit a violation, and several courts have interpreted the intent requirement of the Anti-Kickback Statute to mean that if any one purpose of an arrangement is to induce referrals or purchases of federal healthcare program business, the Anti-

 Kickback Statute has been violated. In addition to criminal fines and penalties set forth under the Anti-Kickback Statute, violations of the Anti-Kickback Statute can result in exclusion or debarment from participation in the federal healthcare programs, as well as substantial penalties under the Civil Monetary Penalties Statute, which imposes penalties against any person or entity that is determined to have presented or caused to be presented a claim to a federal healthcare program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent. A violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act, which, as discussed below, imposes liability on any person or entity that knowingly presents, or causes to be presented, a false or fraudulent claim for payment by a federal healthcare program. Several states and foreign countries also have anti-kickback laws and other fraud and abuse laws that establish similar prohibitions and, in some cases, may apply to items or services reimbursed by any third-party payer, including commercial insurers.

 The U.S. federal Physician Self-Referral Law, commonly referred to as the Stark law, prohibits physicians from referring patients to receive "designated health services" payable by Medicare or Medicaid from entities with which the physician or an immediate family member has a financial relationship, unless an exception applies. Financial relationships include both ownership/investment interests and compensation arrangements. The Stark law is a strict liability statute, meaning that proof of specific intent to violate the law is not required. The Stark law prohibits the submission, or causing the submission, of claims in violation of the law's restrictions on referrals. Penalties for physicians who violate the Stark law include fines as well as exclusion from participation in federal health care programs.

 The federal False Claims Act imposes liability on any person or entity that knowingly presents or causes to be presented a false or fraudulent claim for payment to, or approval by, the U.S. government. Liability under the False Claims Act can give rise to treble damages and civil monetary penalties. In addition to actions initiated by the government itself, the qui tam provisions of the False Claims Act authorize private individuals to bring False Claims Act actions on behalf of the federal government alleging that the defendant has submitted a false claim to the federal government, and to share in a percentage of the recovery. In recent years, the government and qui tam relators have initiated suits resulting in multi-million and multi-billion dollar settlements under the False Claims Act in addition to criminal convictions under applicable criminal statutes. Given the significant size of actual and potential settlements, it is expected that the government and qui tam relators will continue to devote substantial resources and use the False Claims Act to investigate and prosecute healthcare companies' compliance with applicable fraud and abuse laws.

 The federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA") created federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme or artifice to defraud any healthcare benefit program, including private third-party payers or to obtain—by means of false or fraudulent pretenses, representations, or promises—any of the money or property owned by or under the custody or control of any healthcare benefit program; and knowingly and willfully falsifying, concealing, or covering up a material fact or making any materially false, fictitious, or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. The Affordable Care Act ("ACA") amended certain sections of the HIPAA criminal statutes such that a person need not have actual knowledge of the applicable statute or specific intent in order to have committed a healthcare fraud violation.

 As stated above, many states and foreign countries have adopted similar fraud and abuse laws that may be broader in scope and may apply regardless of payer. Violations of any of these laws can lead to additional risk such as risk of plaintiff class actions, state attorney general actions, and investigation by agencies such as the DOJ or the FTC.

 The Physician Payment Sunshine Act, implemented by Section 6002 of the ACA, imposes transparency requirements on certain manufacturers, referred to as "applicable manufacturers," of drugs, devices, biological, or medical supplies for which payment is available under Medicare, Medicaid, the Children's Health Insurance Program ("CHIP"), or a waiver of a plan offered under CHIP. Applicable manufacturers must track and report to the CMS certain payments or "transfers of value" provided to U.S. licensed physicians and teaching hospitals during the preceding calendar year, as well as certain ownership and investment interests held by U.S. licensed physicians and their immediate family members. CMS releases the reported data on a public website on an annual basis. Failure to report as required under the Physician Payment Sunshine Act could subject applicable manufacturers to significant financial penalties, while tracking and reporting the required payments and transfers of value may result in considerable administrative expense. Several states currently have similar laws, and more states may enact similar legislation, some of which may be broader in scope. For example, certain states require the implementation

 of compliance programs, compliance with industry ethics codes, implementation of gift bans, and spending limits, and/or reporting of gifts, compensation, and other remuneration to healthcare professionals.

 We also may be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business. HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act ("HITECH"), and their respective implementing regulations, including the final omnibus rule published by the Department of Health and Human Services Office for Civil Rights ("OCR") in January 2013, restrict the use and disclosure of patient-identifiable health information, mandate the adoption of standards relating to the privacy and security of patient-identifiable health information, and require us to report certain security breaches to healthcare provider customers with respect to such information where we are acting as a HIPAA business associate, as that term is defined, to that customer. In addition to HIPAA criminal penalties, HITECH created four new tiers of civil and monetary penalties and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA privacy and security laws and seek attorneys' fees and costs associated with pursuing federal civil actions. In addition, state laws govern the privacy and security of health information in certain circumstances and impose reporting requirements for data breaches, many of which differ from each other and HIPAA in significant ways and may not have the same effect, thus complicating compliance efforts.

 The use of certain diagnostic products by our potential customers is affected by the Clinical Laboratory Improvement Amendments ("CLIA") and related federal and state regulations that provide for regulation of laboratory testing. CLIA is intended to ensure the quality and reliability of clinical laboratories in the United States by mandating specific standards in the areas of personnel qualifications, administration, and participation in proficiency testing, patient test management, quality assurance, quality control, and inspections. Current or future CLIA requirements or the promulgation of additional regulations affecting laboratory testing may prevent some laboratories, hospitals, providers, or other customers with laboratories from using some or all of our diagnostic products.

 Healthcare Reform

 In the United States and several foreign jurisdictions, there have been, and we expect there may continue to be, a number of legislative and regulatory changes to the healthcare system seeking to reduce healthcare costs that could affect our future results of operations as we begin to commercialize our products.

 In addition, frequently in recent years, other legislative, regulatory, and political changes aimed at regulating healthcare delivery in general and clinical laboratories in particular have been proposed and adopted in the United States. Payment and reimbursement for the laboratory industry and hospital and other healthcare provider services have been under significant pressure. In January 2015, the Department of Health and Human Services ("HHS") announced a plan to shift the Medicare program and the healthcare system at large toward paying providers based on quality, rather than the quantity of care provided to patients.

 Reimbursement

 In most cases, we do not believe that hospitals will specifically seek reimbursement from the government or private insurance companies for their purchase of the Accelerate Pheno system or the Accelerate PhenoTest BC Kit. Instead, we believe that hospitals will recoup such costs by obtaining reimbursement from the government or private insurance companies for in-bed occupancies, which traditionally includes all testing required for admitted patients.

 Hospitals, clinical laboratories, and other healthcare provider customers that may purchase our products, if approved, generally bill various third-party payers to cover all or a portion of the costs and fees associated with diagnostic tests, including the cost of the purchase of our products. We currently expect most of our diagnostic tests will be performed in a hospital inpatient setting, where governmental payers, such as Medicare, generally reimburse hospitals a single bundled payment that is based on the patient's diagnosis under a classification system known as the Medicare severity diagnosis-related groups ("MS-DRGs") classification for all items and services provided to the patient during a single hospitalization, regardless of whether our diagnostic tests are performed during such hospitalization.

 In 2020, the Company received a Current Procedural Terminology ("CPT") code for the rapid diagnosis of patients in a hospital outpatient setting for the Accelerate PhenoTest BC Kit, ID/AST configuration. While the majority of testing remains with the hospital inpatient setting, these reimbursement codes provide opportunities to

 offset a portion of the cost of their testing for outpatient and observation bed patients.

 Environmental Laws

 We use hazardous materials in some of our research, development and manufacturing processes, and our operations are subject to regulation under various federal, state, local, and foreign laws concerning the environment. We believe that our operations are in material compliance with applicable environmental laws and regulations. The costs we incur in complying with such environmental laws and regulations are presently not material to our operations, cash flows or financial condition. It is possible, however, that future developments, including changes in environmental laws and regulations, could lead to material compliance costs, and such costs may have a material adverse effect on our operations, cash flows or financial condition. See "Risk Factors-Risks Related to Our Research and Development Activities-We use hazardous materials in some of our research, development and manufacturing processes and face the accompanying risks and regulations governing environmental safety" for additional information.

 Operations

 Our corporate headquarters are in Tucson, Arizona, where we currently lease approximately 54,092 square feet of office, manufacturing and laboratory space. Further information regarding our Tucson facility is included in Item 2. Properties, and details regarding our lease arrangements are included in Part II, Item 8, Note 9, Leases of this Form 10-K.

 We assemble instruments and formulate, fill, and assemble the kits in our facilities in Tucson, Arizona. Our instruments and kits require certain components that are custom-fabricated to our specifications. Such components include injection-molded plastic components, die-cut laminates and machined mechanical components. We own the necessary production tooling and believe that we will be able to qualify secondary sources as needed to support future demand for our products.

 Raw Materials

 We purchase many different types of raw materials, including plastics, glass, metals, electronic and mechanical sub-assemblies and various biological and chemical products. We seek to ensure continuity of raw material supply by securing multiple options for sourcing and also review relevant sources for compliance with conflict minerals requirements. Many of our components are custom-made by only a few outside suppliers, and certain of the components of our Accelerate Pheno system and in-development Accelerate WAVE system have sole source suppliers.

 The third party manufacturing supply chain for our products remains stable, despite the unprecedented cost increases that we have experienced from many of our suppliers, primarily as a result of labor and supply disruptions and increased inflation over the past several years. The areas of cost increases include raw materials, components, and value-add supplier labor. We believe that we currently have sufficient inventory of Accelerate Pheno system instruments to limit the impact of cost increases on such devices. However, we are being impacted by cost increases to components and raw materials necessary for the production of our Accelerate Pheno kits. Our ability to pass increased material costs to many of our customers is limited because of long-term sales agreements with limits on price increases. Accordingly, we are closely monitoring the ability of all of our suppliers to provide us with the necessary materials and services at reasonable costs and continue to seek alternative sources where appropriate. See "Risk Factors—Risks Related to Our Business and Strategy-Disruptions in the supply of raw materials, consumable goods or other key product components, increased costs or issues associated with their quality from our single source suppliers, could result in a significant disruption in sales and profitability" for additional information.

 Research and Development

 We plan to continue making investments in the research and development of new applications for existing technologies while focusing the largest portion of our research and development efforts on the development of our next generation Accelerate WAVE technology.

 Since the launch of the Accelerate Pheno system, we have focused on product improvements and the development of additional test kits. This includes the PhenoTest BC kit, AST configuration launched in EMEA in

 2021 which provides our customers the ability to use the input of an ID result from another system or methodology but still benefit from rapid AST results using the Accelerate Pheno system. Our objective is to continue to develop test kits that work seamlessly with the Accelerate Pheno system and deliver substantial benefits to microbiology laboratories and to physicians in the treatment of serious infections.

 Our research activity also includes the evaluation and development of (i) technologies to reduce the cost and increase the throughput of AST, (ii) improved AST technologies, (iii) improved ID technologies, and (iv) other platform technologies potentially useful in addressing other parts of the infectious disease laboratory testing workflow. One such program is the development of our next generation AST platform, the Accelerate WAVE system, discussed above.

 Intellectual Property

 We rely on a combination of patent, copyright, trademark and trade secret laws, employee and third-party non-disclosure agreements, license agreements, and other intellectual property protection methods to protect our proprietary rights. We intend to continue developing intellectual property, and we intend to aggressively protect our position in key technologies. Our patented technology covers key components of the Accelerate Pheno system and applied for patents related to our next generation AST platform, the Accelerate WAVE system, and methods, and is, thus, critical to the Company. Our patents are focused on several key technologies, including our automated process for sample preparation, and methods for imaging and analysis of individual pathogen cells. The Company's first patent on the Accelerate Pheno system technology, U.S. Patent No. 7,341,841 titled "Rapid Microbial Detection and Antimicrobial Susceptibility Testing," was issued on March 11, 2008. The patent specification covers methods used to derive ID and antibiotic susceptibility from tests on individual immobilized bacterial cells. As of December 31, 2024, we had 29 issued patents worldwide, including 20 patents issued in the United States and nine issued outside the United States. Our patents are set to expire on various dates in 2022 through 2035. We do not believe any patents that have expired have a material effect on the Company. Additionally, as of December 31, 2024, we had seven patent applications pending worldwide. The Company believes that its patent suite would make it difficult for any other company to conduct rapid AST of individual pathogens utilizing our technology. From a trademark perspective, we had 53 registered marks protecting our brand and prospective products both domestically and internationally.

 Human Capital Resources

 As of December 31, 2024, we had approximately 107 full-time employees worldwide, with approximately 100 employees in the United States and approximately 7 employees outside of the United States, none of whom are represented by a labor union. We have experienced no work stoppages and believe that our employee relations are good.

 Our employees are one of our most important assets and set the foundation for our ability to achieve our strategic objectives, drive operational execution, deliver strong financial performance, advance innovation and maintain our quality and compliance programs.

 The success and growth of our business depends in large part on our ability to attract, retain and develop a diverse population of talented and high-performing employees at all levels of our organization. To succeed in a competitive labor market, we have recruitment and retention strategies that we focus on as part of the overall management of our business, including designing our compensation and benefits programs to be competitive and align with our strategic and stockholders' interests. Some of our key employee benefits include eligibility for health insurance, vacation time, a retirement plan, an employee assistance program, and life and disability coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their needs, including flexible spending accounts, prepaid legal benefits, backup childcare, tuition reimbursement and a wellness program.

 Corporate History and Available Information

 We were incorporated in 1982 in Colorado under the name Sage Resources Corp., and through a series of subsequent transactions, we became Accelerate Diagnostics, Inc., a Delaware corporation, in December 2012. In 2012, our Board of Directors and management team established a new strategic direction for the Company, which was (1) to focus on the internal development, manufacture, and commercialization of the Accelerate Pheno system and (2) to discontinue efforts to develop and actively market OptiChem and our other surface chemistry products. Our Board of Directors and management pursued this new strategic direction based on the belief that we could

 internally develop and commercialize the Accelerate Pheno system, formerly called the BacCel System.

 Item 1A. Risk Factors

 Investing in our securities involves a high degree of risk. You should carefully consider the risks described below, in addition to the other information included or incorporated by reference in this Form 10-K, including our financial statements and the related notes. If any of the following risks materialize, our business, financial condition, results of operations or growth prospects could be materially adversely affected, and the value of an investment in our common stock may decline significantly.

 Risks Related to Our Financial Condition, Liquidity and Indebtedness

 Our financial condition, including our substantial indebtedness, raises substantial doubt regarding our ability to continue as a going concern.

 Since inception, we have not achieved profitable operations or positive cash flows from operations. Our accumulated deficit totaled $718.9 million as of December 31, 2024. During the year ended December 31, 2024, we had a net loss of $50.0 million and negative cash flows from operations of $24.2 million. As of December 31, 2024, we had $16.3 million in cash and cash equivalents and negative working capital of $(9.0) million. Additionally, we have a substantial amount of indebtedness comprised of $71.0 million aggregate principal amount of 5.00% Notes and $16.0 million aggregate principal amount of 16.00% Super-Priority Senior Secured PIK Notes due 2025 (the "16.00% Notes" and together with the 5.00% Notes, the "Notes") outstanding.

 As a result of our financial condition, we have determined that, as of the date of this Form 10-K filing, there is substantial doubt about our ability to continue as a going concern, as we do not currently have adequate financial resources to fund our forecasted operating costs for at least twelve months from the filing date of this Form 10-K. The reports of our independent registered public accountants on our financial statements as of December 31, 2024 and 2023 and for each of the two years in the period ended December 31, 2024 also include explanatory language describing the existence of substantial doubt about our ability to continue as a going concern. The presence of this going concern explanatory language could adversely affect our ability to raise additional debt or equity financing, as well as to further develop and market our products, all of which could have a material adverse impact on our business, results of operations and financial condition. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations - "Capital Resources and Liquidity" and Part II, Item 8, Note 1, Organization and Nature of Business; Basis of Presentation; Principles of Consolidation of this Form 10-K for additional information.

 Management currently believes that it will be necessary for us to secure additional funds to continue our existing business operations and to fund our obligations. While we continue to explore additional funding in the form of potential equity and/or debt financing arrangements or similar transactions, there can be no assurance the necessary financing will be available on terms acceptable to us, or at all. If we raise funds by issuing equity securities, dilution to stockholders may result. Any equity securities issued may also provide for rights, preferences or privileges senior to those of holders of common stock. If we raise funds by issuing additional debt, it is likely any new debt would have rights, preferences and privileges senior to common stockholders. The terms of borrowing could impose significant restrictions on our operations. The capital markets have in the past, and may in the future, experience periods of upheaval that could impact the availability and cost of equity and debt financing. In addition, changes in federal fund rates set by the Federal Reserve, such as the significant increases experienced throughout 2022 and 2023, which serve as benchmark rates on borrowing, and other general economic conditions have impacted, and in the future may further impact, the cost of debt financing or refinancing existing debt.

 In September 2024, we announced that we have retained Perella Weinberg Partners to assist with the review of strategic alternatives. Although we are actively considering all available strategic alternatives to maximize value, if we are unable to obtain adequate capital resources to fund operations, we would not be able to continue to operate our business pursuant to our current plans. This may require us to, among other things, materially modify our operations to reduce spending; sell assets or operations; delay the implementation of, or revise certain aspects of, our business strategy; pursue strategic alternatives; file a voluntary petition for relief under Chapter 11 of the United States Bankruptcy Code in order to implement a restructuring; or discontinue our operations entirely.

 We have substantial indebtedness, which could have important consequences to our business.

 We have a substantial amount of indebtedness primarily comprised of our Notes. As of December 31, 2024, we had $71.0 million aggregate principal amount of 5.00% Notes outstanding, which mature on December 15, 2026, and $16.0 million aggregate principal amount of 16.00% Notes, which mature on December 31, 2025. We pay interest on the 5.00% Notes and 16.00% Notes by payment-in-kind ("PIK"), through the issuance of additional 5.00% Notes ("5.00% PIK Notes") and additional 16.00% Notes ("16.00% PIK Notes"), respectively.

 The indenture governing the 5.00% Notes (the "5.00% Notes Indenture") and the indenture governing the 16.00% Notes (the 16.00% Notes Indenture" and together with the 5.00% Notes Indenture, the "Indentures") contain customary events of default. The Indentures provide that we may be required to repay amounts due under the Indentures, as applicable, in the event that there is an event of default for the respective Notes that results in the principal, premium and interest, if any, becoming due prior to the maturity date for the respective Notes.

 Any event of default or declaration of acceleration under one debt instrument could result in an event of default and declaration of acceleration under one or more of our other instruments, including with respect to the Indentures. There can be no assurance that we will be able to meet our obligations under our indebtedness if they become due, or that we will be able to refinance our indebtedness on acceptable terms or at all, which could adversely affect our business, financial condition and liquidity, as discussed elsewhere under "Risks Related to Our Financial Condition, Liquidity and Indebtedness."

 In addition, our indebtedness could, among other things:

 • heighten our vulnerability to adverse general economic conditions and heightened competitive pressures;
 • require us to dedicate a larger portion of our cash flow from operations to interest payments, limiting the availability of cash for other purposes;
 • limit our flexibility in planning for, or reacting to, changes in our business and industry;
 • impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes;
 • impact our ability to continue as a going concern; and
 • necessitate a restructuring under Chapter 11 of the United States Bankruptcy Code.

 The terms of certain of our indebtedness include a number of restrictive covenants that impose significant operating and financial restrictions on us and limit our ability to engage in actions that may be in our long-term best interests. For example, the 16.00% Notes Indenture contains various affirmative, negative and financial covenants that, among other things, may restrict the ability of us and our subsidiaries to incur additional indebtedness, create certain liens, merge or consolidate with another entity, pay dividends or repurchase stock, and sell all or substantially all of our assets.

 Furthermore, we and certain of our subsidiaries have pledged assets, including but not limited to certain accounts, equipment, fixtures and intellectual property, as collateral for our repayment obligations relating to the Notes. If we were unable to repay any amount under the Notes when due and payable, the collateral agent could proceed against the collateral that secures such indebtedness.

 Servicing our debt will require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our debt.

 Our ability to make scheduled payments on the principal of or to refinance our indebtedness, primarily the Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive.

 Our ability to repay our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

 To the extent we deliver shares upon conversion of the 5.00% Notes, the ownership interests of existing stockholders could be diluted and our stock price may be adversely impacted.

 Upon conversion of the 5.00% Notes, we will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at the Company's election. To the extent we choose to deliver shares upon conversion of some or all of the 5.00% Notes, this will result in a dilution to the ownership interests of existing stockholders and may depress our stock price.

 We may seek the protection of the Bankruptcy Court, which may harm our business, adversely affect our ability to retain key personnel, and result in a significant loss of value for our stockholders.

 We have engaged financial and legal advisors to assist us in, among other things, analyzing various strategic alternatives to address our liquidity and capital structure. However, there can be no assurance that the strategic review will be successful, and a filing under Chapter 11 may be unavoidable. Seeking Bankruptcy Court protection could have a material adverse effect on our business, financial condition, results of operations and liquidity. So long as the process related to a Chapter 11 proceeding continues, our senior management would be required to spend a significant amount of time and effort dealing with the reorganization instead of focusing exclusively on our business operations. Bankruptcy Court protection also might make it more difficult to retain management and other key personnel necessary to the success and growth of our business. The longer a Chapter 11 proceeding continues, the more likely it is that our customers would lose confidence in our ability to reorganize our businesses successfully and would seek to establish alternative commercial relationships. Additionally, all of our indebtedness is senior to the existing common stock in our capital structure. As a result, if we seek relief under Chapter 11, existing shares of our common stock may be canceled, with a very limited recovery or no recovery for holders of our common stock. Moreover, if we execute a restructuring outside of Chapter 11, such transaction could result in substantial dilution to existing holders of our common stock. Therefore, trading in our securities is highly speculative and poses substantial risks.

 Risks Related to Our Business and Strategy

 We have limited revenues from our products and no assurance of future revenues.

 We have received limited revenue from sales of the Accelerate Pheno system and the Accelerate PhenoTest BC Kit and Accelerate Arc system. As a result, during the years ended December 31, 2024 and 2023, we experienced losses from operations. Our future revenues are dependent on the successful commercialization of our products and there can be no assurance that we will be successful at the levels necessary to cover the costs of operations. If we are unsuccessful in generating sufficient revenues from our current and future products, we will likely continue to experience losses from operations and negative cash flow.

 We have a history of losses and expect to continue to incur losses in the future, and we cannot be certain that we will achieve or sustain profitability.

 Until we received FDA approval to market the Accelerate Pheno system, we were a development-stage company and therefore incurred significant losses in prior years. While we are currently commercializing the Accelerate Pheno system and the Accelerate Arc system, we have incurred significant costs in connection with the development and commercialization of our technology and expect to continue to incur further costs in the development and commercialization of our future products, including the Accelerate WAVE system. There is no assurance that we will achieve sufficient revenues to offset anticipated operating costs, and we expect to continue to incur losses in the future. Our ability to achieve or sustain profitability depends on numerous factors including the market acceptance of our products, product quality, future product development and our market penetration and margins. If we are unsuccessful in generating sufficient revenues from our products, we will likely continue to experience losses from operations and negative cash flow. Although we anticipate deriving revenues from the sale of our products, no assurance can be given that these products can be sold on a net profit basis. If we achieve profitability, we cannot give any assurance that we will be able to sustain or increase profitability on a quarterly or annual basis in the future.

 Our future profitability and continued existence are dependent in large part upon the successful commercialization of the Accelerate Pheno system and Accelerate Arc system and further development and commercialization of associated test kits, and the Accelerate WAVE system.

 Our principal business strategy involves the successful commercialization of the Accelerate Pheno system and further development and commercialization of associated test kits, the Accelerate Arc module and BC kit and future products, including the Accelerate WAVE system. On June 30, 2015, we declared our conformity to the European In Vitro Diagnostic Directive 98/79/ EC and applied a CE Mark to the Accelerate Pheno system and the Accelerate PhenoTest BC kit for in vitro diagnostic use. On February 23, 2017, the FDA granted our de novo request to market our Accelerate Pheno system and Accelerate PhenoTest BC kit. We have and will continue to dedicate a significant amount of resources to market and sell the Accelerate Pheno system. Likewise, we plan to continue our investment in the development of additional test kits and the commercialization of the Accelerate Pheno system in the United States and other jurisdictions in which we intend to pursue marketing authorization. There can be no assurance that we will successfully commercialize the Accelerate Pheno system, any associated test kits, including the Accelerate PhenoTest BC kit, or further develop and commercialize complimentary products such as the PhenoTest BC Kit, AST configuration, the Accelerate Arc system, including the related BC kit, and future products, such as the Accelerate WAVE system.

 Any failure to do so could lead to an impairment of certain of our intellectual property, inventory, property and equipment, and may result in our ceasing operations. We may also be required to expend significantly more resources than planned in this process and, as a result, we may have to cease investing in the Accelerate Pheno, Accelerate Arc or Accelerate WAVE systems, or developing other products.

 Additionally, our efforts to educate hospitals on the benefits of our products require significant resources, and we may experience reluctance from hospitals to purchase our products. If we fail to successfully commercialize our products, we may never receive a return on the significant investments in product development, sales and marketing, regulatory compliance, manufacturing and quality assurance we have made, and on further investments we intend to make, and may fail to generate revenue and gain economies of scale from such investments.

 Furthermore, the potential market for our products may not expand as we anticipate or may even decline based on numerous factors, including the introduction of superior alternative product or other factors beyond our control. If we are unable to adequately expand the market for our products, this failure would have a material adverse effect on our ability to execute on our business plan and ability to generate revenue.

 We have entered into the Sales and Marketing Agreement with BD and will substantially depend on BD for the successful commercialization of our products.

 As part of our collaboration with BD pursuant to the Sales and Marketing Agreement, BD will perform certain sales, tactical marketing, technical service call forwarding, order preparation, research and development support and/or regulatory activities on our behalf as our exclusive sales agent for certain of our products, including the Accelerate Pheno system, Accelerate Arc system and related BC Kits. The successful commercialization of our products, including payments for BD exclusivity is dependent on our ability to generate revenue from our

 arrangement with BD. This will depend on BD's ability to successfully perform the responsibilities assigned to it pursuant to the Sales and Marketing Agreement. While BD is largely responsible for the speed and scope of sales and marketing efforts, we cannot assure you that BD will dedicate the resources necessary to successfully perform its responsibilities pursuant to the Sales and Marketing Agreement, and our ability to cause BD to increase the speed and scope of its efforts may be limited. In addition, sales and marketing efforts could be negatively impacted by the delay or failure by us to obtain additional supportive clinical trial data for our products. We cannot predict the success of our collaboration with BD, and there can be no assurance that the efforts of BD will meet our expectations or result in any significant product sales or cost savings within the anticipated time frame or at all.

 In the event that BD fails to perform under the Sales and Marketing Agreement, or if the Sales and Marketing Agreement is terminated, this could delay our product commercialization efforts, which would materially and adversely affect our business, financial condition, results of operations and cash flows. The termination of the Sales and Marketing Agreement could also require us to revise our commercialization and business strategy going forward and divert management attention and resources. In addition, the termination of the Sales and Marketing Agreement could materially impact our ability to enter into additional collaboration agreements with new partners on favorable terms, if at all.

 Our future product candidates have not obtained marketing authorization from the FDA, and they may never obtain such marketing authorization or other regulatory clearance.

 Our success in part depends on our ability to obtain additional product marketing authorizations from the FDA for product candidates in our pipeline, including our Accelerate WAVE system. If our attempts to obtain marketing authorization or other regulatory clearance are unsuccessful, we may be unable to generate sufficient revenue to sustain and grow our business. Our future product candidates may not be sufficiently sensitive or specific to obtain, or may prove to have other characteristics that preclude our obtaining, marketing authorization from the FDA or regulatory clearance. The process of obtaining regulatory clearance is expensive and time-consuming and can vary substantially based upon, among other things, the type, complexity and novelty of our product candidates. Changes in regulatory policy, changes in or the enactment of additional statutes or regulations or changes in regulatory review for each submitted product application may cause delays in the clearance of, or receipt of marketing authorization from the FDA for, a product candidate or rejection of a regulatory application altogether. The FDA has substantial discretion in the de novo review and clearance processes and may refuse to accept any application or may decide that our data is insufficient for clearance and require additional pre-clinical, clinical or other studies. In addition, varying interpretations of the data obtained from pre-clinical and clinical testing could delay, limit or prevent marketing authorization from the FDA or regulatory clearance of a product candidate. Any marketing authorization from the FDA or regulatory clearance we ultimately obtain may be limited or subject to restrictions or post-market commitments that render the product candidate not commercially viable.

 We may not be able to correctly estimate or control our future operating expenses, which could lead to cash shortfalls, and impact our ability to continue as a going concern.

 Our operating expenses may fluctuate significantly in the future as a result of a variety of factors, many of which may be outside of our control. These factors include, but are not limited to:

 • the expenses we incur for research and development required to maintain and improve our technology, including the continuing development of the Accelerate Pheno and Accelerate Arc systems, and development costs for new products, including the Accelerate WAVE system;
 • the expenses we incur in connection with the development, marketing authorization and regulatory clearance of the use of the Accelerate Pheno system to test on additional specimen types and our Accelerate Arc system, as well as in connection with the development of new products, including the Accelerate WAVE system;
 • the costs of preparing, filing, prosecuting, defending and enforcing patent claims and other intellectual property related costs, including litigation costs and the results of such litigation;
 • the expenses we incur in connection with commercialization activities, including product marketing, sales and distribution expenses;
 • the costs incurred to build manufacturing capabilities;
 • the expenses to implement our sales strategy;
 • the costs to attract and retain personnel with the skills required for effective operations; and
 • the costs associated with being a public company.

 Our budgeted expense levels are based in part on our expectations concerning future revenues from sales of the Accelerate Pheno system, the Accelerate Arc system, as well as our assessment of the future investments needed to expand our commercial organization and support research and development activities in connection with the Accelerate Pheno and Accelerate Arc systems, as well as future products, including the Accelerate WAVE system. We may be unable to reduce our expenditures in a timely manner to compensate for any unexpected events or a shortfall in revenue. Accordingly, a shortfall in demand for our products or other unexpected events could have an immediate and material impact on our cash levels.

 If we do not achieve our projected development goals in the time frames we announce and expect, the commercialization of our products may be delayed and, as a result, our stock price may decline.

 From time to time, we estimate the timing of the accomplishment of various scientific, clinical, regulatory and other product development goals. These goals may include the commencement or completion of clinical trials and the submission of regulatory filings, including those related to the ongoing development of our Accelerate WAVE system. From time to time, we may publicly announce the expected timing of some of these goals. All of these goals are, and will be, based on a variety of assumptions. The actual timing of these goals can vary significantly compared to our estimates, in some cases for reasons beyond our control. We may also experience numerous unforeseen events that could delay or prevent our ability to receive marketing approval or commercialize our product candidates, including the uncertainties and risks set forth in this Form 10-K and in our other filings with the SEC. If we do not meet our goals as publicly announced, the commercialization of our product candidates may be delayed and, as a result, our stock price may decline.

 We may not be able to enhance the capabilities of our current and new products to keep pace with our industry's rapidly changing technology and customer requirements.

 Our industry is characterized by rapid technological changes, frequent new product introductions and enhancements and evolving industry standards. Our future success will depend significantly on our ability to enhance our current products and develop or acquire and market new products that keep pace with technological developments and evolving industry standards as well as respond to changes in customer needs. New technologies, techniques or products could emerge that might offer better combinations of price and performance than the products and systems that we plan to sell. It is critical to our success that we anticipate changes in technology and customer requirements and physician, hospital and healthcare provider practices and successfully introduce new, enhanced and competitive technologies to meet our prospective customers' needs on a timely and cost-effective basis. At the same time, however, we must carefully manage our introduction of new products. If potential customers believe that such new products will offer enhanced features or be sold for a more attractive price, they may delay purchases of existing products until such new products are available.

 Further, there can be no assurance that we will be successful in developing or acquiring product enhancements or new products to address changing technologies and customer requirements adequately, that we can introduce such products on a timely basis or that any such products or enhancements will be successful in the marketplace. If we are unable to successfully develop or acquire new products or if the market does not accept our products, or if we experience difficulties or delays in the final development and commercialization of our products, we may be unable to attract additional customers for our products or strategic partners to license our products.

 The failure of our current or any future diagnostic products to perform as expected could significantly impair our reputation and the public image of our products, and we may be subject to legal claims arising from any defects or errors.

 Our success will depend on the market's confidence that our technologies can provide reliable, high-quality diagnostic results. We believe that our customers are likely to be particularly sensitive to any defects or errors in the Accelerate Pheno system or any future diagnostic products, including the Accelerate WAVE system. As is typical of complex diagnostic systems, we occasionally experience support issues or other performance problems with the Accelerate Pheno system. We have also experienced customer returns of our Accelerate Pheno system, some of which related to quality issues. We could face warranty and liability claims against us and our reputation could suffer as a result of such failures. We cannot assure you that our product liability insurance would adequately protect our assets from the financial impact of defending a product liability claim. Any product liability claim brought against us, with or without merit, could increase our product liability insurance rates or prevent us from securing insurance coverage in the future. In addition, the FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or

 manufacture of a product or in the event that a product poses an unacceptable risk to health. A recall, material liability claim or other occurrence that harms our reputation or decreases market acceptance of our products could cause us to incur significant costs, divert the attention of our key personnel or cause other significant customer relations problems.

 In the past, we have experienced disappointing or negative publication results regarding the efficacy of our products. Such negative publicity could diminish our reputation and future sales of our products, which could have a material impact on our financial performance.

 If treatment guidelines for bacterial infections change, or the standard of care evolves, we may need to redesign and seek new marketing authorization from the FDA for our product candidates.

 If treatment guidelines for bacterial infections change, or the standard of care evolves, we may need to redesign and seek new marketing authorization from the FDA or other regulatory clearance for our product candidates. If treatment guidelines change so that different treatments become desirable, the Accelerate Pheno system may no longer provide the information sought by physicians, and we could be required to seek marketing authorization from the FDA or other regulatory clearance for a revised product.

 Breaches of our information technology systems could have a material adverse effect on our operations and potentially result in liability, depending on the type of breach and information compromised.

 We rely on information technology systems to process, transmit and store electronic information, which may include protected health information, in our day-to-day operations. In addition, our research and development operations are highly dependent on our information technology and storage. Our products also include software and data components. Our information technology systems have been subjected to computer viruses or other malicious codes and phishing attacks, and we expect to be subject to similar viruses and codes in the future. Attacks on our information technology systems or products could result in our intellectual property, unsecured protected health information, and other confidential information being lost or stolen, including the disclosure of our trade secrets, disruption of our operations, loss of valuable research and development data, the need to notify individuals whose information was disclosed, increased costs for security measures or remediation costs and diversion of management attention and other negative consequences. While we will continue to implement protective measures to reduce the risk of and detect future cybersecurity incidents, cyber-attacks are becoming more sophisticated and frequent, and the techniques used in such attacks change rapidly. There can be no assurance that our protective measures will prevent future attacks that could have a significant impact on our business. There also can be no assurance that our cyber insurance will be sufficient to cover the total loss or damage caused by a cyber-attack. In addition, the costs of responding to and recovering from such incidents may not be covered by insurance.

 Failure to comply with a variety of U.S. and international privacy laws to which we are subject could harm the Company.

 Any failure by us or our vendor or other business partners to comply with federal, state or international privacy, data protection or security laws or regulations relating to the collection, use, retention, security and transfer of personally identifiable information could result in regulatory or litigation-related actions against us, legal liability, fines, damages, ongoing audit requirements and other significant costs. A significant data privacy regulation is the General Data Protection Regulation, which applies to the processing of personal information collected from individuals located in the European Union and has created new compliance obligations and has significantly increased fines for noncompliance. Substantial expenses and operational changes may be required in connection with maintaining compliance with such laws, and in particular certain emerging privacy laws are still subject to a high degree of uncertainty as to their interpretation and application.

 We are dependent on our key employees. If we are unable to recruit, train and retain qualified personnel, we may not achieve our goals.

 Because of the complex and technical nature of our products and the dynamic market in which we compete, our future success depends on our ability to recruit, train and retain key personnel, including our senior management, research and development, science and engineering, manufacturing and sales and marketing personnel. For example, we are highly dependent on the management and business expertise of Jack Phillips, our President and Chief Executive Officer. We do not maintain key person life insurance for Mr. Phillips or any of our employees. Our industry is very competitive for qualified personnel. To the extent that the services of Mr. Phillips

 would be unavailable to us, we may be unable to employ another qualified person with the appropriate background and expertise to replace Mr. Phillips on terms suitable to us. Our growth depends, in particular, on attracting, retaining and motivating highly trained sales personnel with the necessary scientific background and ability to understand our systems and pathogens at a technical level. In addition, we may need additional employees at our manufacturing facilities to meet demand for our products as we scale up our sales and marketing operations. We have various programs designed to improve employee retention, but there is no assurance that we will not continue to experience elevated employee attrition levels, which could negatively impact our ability to develop, implement, support and sell our products.

 Our industry is highly competitive, and we may not be successful in competing with our competitors. We currently face competition from new and established competitors and expect to face competition from others in the future, including those with new products, technologies or techniques.

 The industry in which we compete is subject to rapid technological changes, and we face and expect to continue to face strong competition for our products. Many of our competitors and potential competitors may have substantially greater research and development, financial, manufacturing, customer support, sales and marketing resources, larger customer bases, longer operating histories, greater name recognition and more established relationships in the industry than we do. In addition, some of our competitors may, individually or together with companies affiliated with them, have greater human and scientific resources than we do.

 Our competitors could develop new products or technologies that are more effective than the Accelerate Pheno system, the Accelerate Arc system and any of our other products or product candidates. Additionally, we expect to face further competitive pressure resulting from the emergence of new ID or AST techniques or tests. For example, we are aware that some hospitals have begun using manual methods created through laboratory developed tests, which have been validated for internal hospital-specific use to deliver ID and AST results. Any of these newly developed products, technologies, and techniques may offer a better combination of price and performance than our products and systems. Our failure to compete effectively could materially and adversely affect our business, financial condition and operating results.

 We generate a portion of our future revenue internationally and are subject to various risks relating to our international activities which could adversely affect our operating results.

 We market and sell the Accelerate Pheno system in other countries outside of the United States. In order to market our products in certain foreign jurisdictions, we, or our distributors or partners, must obtain separate regulatory approvals and comply with numerous and varying regulatory requirements regarding safety and efficacy and governing, among other things, clinical studies and commercial sales and distribution of our products. The approval procedure varies among countries and can involve additional testing. In addition, in many countries outside the United States, a product must be approved for reimbursement before the product can be approved for sale in that country. We may not obtain approvals from regulatory authorities outside the United States on a timely basis, if at all, which could harm our ability to expand into markets outside the United States. In addition, engaging in international business involves a number of other difficulties and risks, including:

 • required compliance with existing and changing foreign healthcare and other regulatory requirements and laws, such as those relating to patient privacy or handling of bio-hazardous waste;
 • required compliance with anti-bribery laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, data privacy requirements, labor laws and anti-competition regulations;
 • export and import restrictions;
 • various reimbursement and insurance regimes;
 • laws and business practices favoring local companies;
 • longer payment cycles and difficulties in enforcing agreements and collecting receivables through certain foreign legal systems;
 • political, economic and social instability, including instability resulting from the ongoing wars and conflicts between Russia and Ukraine and between Israel and Hamas, as well as continued and any new sanctions against Russia;
 • potentially adverse tax consequences, tariffs, customs charges, bureaucratic requirements and other trade barriers;
 • foreign exchange controls;
 • fluctuations due to changes in foreign currency exchange rates;
 • difficulties and costs of staffing and managing foreign operations; and

 • impediments with protecting or procuring intellectual property rights.

 In particular, further escalation or expansion of ongoing international wars and conflicts could impact our European business operations, including disrupting our sales channels and marketing activities, as well as negatively impacting the demand for our products.

 In addition, changes in policies and/or laws of the United States, including as a result of the recent changes in the presidential administration, or foreign governments resulting in, among other changes, higher taxation, tariffs or similar protectionist laws, currency conversion limitations, limitations on business operations, or the nationalization of private enterprises could reduce the anticipated benefits of international operations and could have a material adverse effect on our ability to expand internationally.

 Our employees, independent contractors, principal investigators, consultants, commercial partners, vendors and other agents may engage in misconduct or other improper activities, including non-compliance with legal standards and requirements.

 We are exposed to the risk of fraud or other misconduct by our employees, independent contractors, principal investigators, consultants, commercial partners, vendors and other agents, including BD. Misconduct by these parties could include intentional, reckless or negligent failures to: (i) comply with the laws and regulations of the FDA, CMS, the HHS Office of Inspector General, Office for Civil Rights and other similar foreign regulatory bodies; (ii) provide true, complete and accurate information to the FDA and other similar regulatory bodies; (iii) comply with manufacturing requirements of the FDA and other similar regulatory bodies and manufacturing standards we have established; (iv) comply with healthcare fraud and abuse laws and regulations in the United States and similar foreign fraudulent misconduct laws; or (v) report financial information or data accurately, or disclose unauthorized activities to us. These laws may impact, among other things, our activities with principal investigators and research subjects, as well as our sales, marketing and education programs. In particular, the promotion, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing, unauthorized use of protected health information and data breaches, and other abusive practices. These laws may restrict or prohibit a wide range of activities related to pricing, discounting, sales, marketing and promotion, patient support, royalty, consulting, research and other business arrangements, as well as the improper use of patient information obtained in the course of clinical studies. We currently have a compliance program that includes a code of conduct applicable to all of our employees and foreign distributors, but it is not always possible to identify and deter employee and/or commercial partner misconduct, and our code of conduct and the other policies and practices we have put into place to identify, address, and prevent inappropriate conduct may not be effective in controlling unknown or unmanaged risks or losses, or in protecting us from governmental investigations or other actions or lawsuits stemming from a failure to comply with these laws or regulations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the imposition of civil, criminal and administrative penalties, damages, monetary fines, disgorgement, individual imprisonment, corporate integrity agreements, possible exclusion from participation in Medicare, Medicaid and other federal healthcare programs, contractual damages, reputational harm, diminished profits and future earnings, and curtailment of our operations. Any of these actions or investigations could result in substantial costs to us, including legal fees, and divert the attention of management from operating our business.

 Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the market in which we compete achieves the forecasted growth, our business could fail to grow at similar rates, if at all.

 Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. Any estimates and forecasts in this Form 10-K relating to the size and expected growth of our market, total available market, estimated test and placement volume and estimated pricing, may prove to be inaccurate, which may have negative consequences, such as overestimation of our potential market opportunity. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all.

 We are exposed to risks associated with long-lived assets that may become impaired and result in an impairment charge.

 The carrying amounts of long-lived assets are affected whenever events or changes in circumstances

 indicate that the carrying amount of any asset may not be recoverable. Property and equipment includes Accelerate Pheno systems (also referred to as instruments) used for sales demonstrations, instruments under rental agreements and instruments used for research and development. Similarly, the recoverability of the book value of instrument-related inventory could be impacted by changes in growth expectations and require a reduction in their carrying value to the lower of cost or market.

 Adverse events or changes in circumstances may affect the estimated discounted future cash flows expected to be derived from long-lived assets. If at any time we determine that an impairment has occurred, we will be required to reflect the impaired value as a charge, resulting in a reduction in earnings, such impairment is identified and a corresponding reduction in our net asset value. In the future, we may incur impairment charges. A material reduction in earnings resulting from such a charge could cause us to fail to meet the expectations of investors and securities analysts, which could cause the price of our stock to decline.

 Providing instrument systems to our customers through reagent rental agreements may harm our liquidity.

 Many of our systems are provided to customers via "reagent rental" agreements, under which customers are generally afforded the right to rent the instrument and the rental fee is paid through a commitment by the customer to purchase minimum quantities of reagents and test kits over a period of time. Accordingly, we must either incur the expense of manufacturing instruments well in advance of receiving sufficient revenues from test cartridges to recover our expenses or obtain third party financing sources for the purchase of our instrument. The amount of capital required to provide instrument systems to customers depends on the number of systems subject to such arrangements. Our ability to generate capital to cover these costs depends on the amount of our revenues from sales of reagents and test cartridges sold through our reagent rental agreements. We do not currently sell enough reagents and test cartridges to recover all of our fixed expenses, and therefore we currently have a net loss. If we cannot sell a sufficient number of reagents and test cartridges to offset our fixed expenses, our liquidity will continue to be adversely affected.

 If we fail to estimate customer demand properly, our financial results could be harmed.

 Our products are manufactured based on estimates of customers' future demand and our manufacturing lead times are very long. This could lead to a significant mismatch between supply and demand, giving rise to product shortages, excess inventory or further instrument-related inventory write-downs, and make our demand forecast more uncertain. In order to have shorter shipment lead times for our customers, we have built up inventory for anticipated growth which has not occurred, or may build up inventory to serve what we believe is pent-up demand. In periods with limited available capacity, we may and have placed inventory orders significantly in advance of our normal lead times, which could negatively impact our financial results. Additionally, customer behavior changes due to significant events and economic conditions have historically made it more difficult for us to estimate future demand. In estimating demand, we make various assumptions, any of which may and have been incorrect. If we are unable to accurately anticipate demand for our products, our business and financial results could be adversely impacted. For example, excess inventory write-downs were recorded during the year ended December 31, 2023 as a result of excess quantities of instrument inventory on hand above and beyond our forecast of future demand for those products.

 Situations that may result in excess or obsolete inventory include:

 • changes in business and economic conditions, including downturns in our target markets and/or overall economy;
 • changes in consumer confidence caused by changes in market conditions, including changes in the credit market;
 • a sudden and significant decrease in demand for our products;
 • a higher incidence of inventory obsolescence because of rapidly changing technology or customer requirements;
 • our introduction of new products resulting in lower demand for older products;
 • less demand than expected for newly-introduced products; or
 • increased competition, including competitive pricing actions.

 The cancellation or deferral of customer purchase orders could result in our holding excess inventory, which could adversely affect our gross margins. In addition, because we often sell a substantial portion of our products in

 the last month of each quarter, we may not be able to reduce our inventory purchases in a timely manner in response to customer cancellations or deferrals. We could be required to further write-down our inventory to the lower of cost or net realizable value, and we could experience a reduction in average selling prices if we incorrectly forecast product demand, any of which could harm our financial results.

 Conversely, if we underestimate our customers' demand for our products, our partners may not have adequate lead-time or capacity to increase production and we may not be able to obtain sufficient inventory to fill customers' orders on a timely basis. We may also face supply constraints caused by natural disasters or other factors as discussed in this "Risk Factors" section. In such cases, even if we are able to increase production levels to meet customer demand, we may not be able to do so in a cost-effective or timely manner. If we fail to fulfill our customers' orders on a timely basis, or at all, our customer relationships could be damaged, we could lose revenue and market share and our reputation could be damaged.

 The COVID-19 pandemic has adversely affected our business and a resurgence of COVID-19 or the occurrence of another health epidemic or pandemic may have an adverse impact on our business in the future.

 Our business, including our workforce, supply chain and customer base, has been adversely affected by COVID-19 in the past and a resurgence of COVID-19 or the occurrence of another health epidemic or pandemic may adversely affect us in the future. The COVID-19 pandemic, containment measures, and downstream impacts to hospital staffing and financial stability significantly impacted our business and results of operations, starting in the first quarter of 2020 and continuing through 2022, albeit to a lesser degree. For example, we experienced diminished access to our customers, including hospitals, which severely limited our ability to sell and, to a lesser degree, implement previously contracted Accelerate Pheno systems. More recently, hospital turnover resulting from burnout and financial challenges driven by inflation and other factors continued to divert the attention of hospital decision makers and impact our ability to access capital markets on terms that are not detrimental to our business.

 Disruptions in the supply of raw materials, consumable goods or other key product components, or issues associated with their quality from our single source suppliers, could result in a significant disruption in sales and profitability.

 We must manufacture or engage third parties to manufacture components of our products in sufficient quantities and on a timely basis, while maintaining product quality, acceptable manufacturing costs and complying with regulatory requirements. Certain of our components are custom-made by only a few outside suppliers and, in certain instances, we have a sole source supply for key product components. We may be unable to satisfy our forecast demand from existing suppliers for our products, or we may be unable to find alternative suppliers for key product components or ancillary items at reasonably comparable prices. If this occurs, we may be unable to manufacture our products, meet key development milestones, and/or meet our customers' needs in a timely manner or at all.

 Additionally, we have entered into supply agreements with most of our suppliers to help ensure component availability and flexible purchasing terms with respect to the purchase of such components. If our suppliers discontinue production of a key component for one or more of our products, we may be unable to identify or secure a viable alternative on reasonable terms, or at all, which could limit our ability to manufacture our products. While we may be able to modify our product candidates to utilize a new source of components, we may need to secure marketing authorization from the FDA or other regulatory clearance for the modified product, and it could take considerable time and expense to perform the requisite tasks prior to seeking such authorization.

 In determining the required quantities of our products and our manufacturing schedule, we will need to make significant judgments and estimates regarding factors such as market trends and any seasonality with respect to our sales. Because of the inherent nature of estimates, there could be significant differences between our estimates and the actual amounts of products that we require. This can result in shortages if we fail to anticipate demand, or excess inventory and write-offs if we order more than we need.

 Reliance on third-party manufacturers entails risk to which we would not be subject if we manufactured these components ourselves, including:

 • reliance on third parties for regulatory compliance and quality assurance;

 • possible breaches of manufacturing agreements by the third parties because of factors beyond our control;
 • possible regulatory violations or manufacturing problems experienced by our suppliers;
 • possible termination or non-renewal of agreements by third parties, based on their own business priorities, at times that are costly or inconvenient for us;
 • the potential obsolescence and/or inability of our suppliers to obtain required components;
 • the potential delays and expenses of seeking alternate sources of supply or manufacturing services;
 • the inability to qualify alternate sources without impacting performance claims of our products;
 • reduced control over pricing, quality and timely delivery due to the difficulties in switching to alternate suppliers or assemblers; and
 • increases in prices of raw materials and key components.

 For example, we are currently experiencing unprecedented cost increases from many of our suppliers, primarily as a result of labor and supply disruptions and increased inflation. The areas of cost increases include raw materials, components, and value-add supplier labor. We currently have sufficient inventory of Accelerate Pheno system instruments to limit the impact of cost increases on such devices. However, we are being impacted by cost increases to components and raw materials necessary for the production of our consumable test kits. Our kits require these components and raw materials, and many of our supply contracts permit the supplier to pass on certain inflation increases to us. Moreover, our ability to pass on cost increases to our consumable test kit customers is limited by long-term contractual price commitments. Prolonged elevated supply costs and further cost increases may further impact our cost to manufacture our Accelerate Pheno and Accelerate Arc systems and to develop our Accelerate WAVE system. The supply cost increases we are experiencing and may experience in the future may materially reduce our gross profit margins, thereby negatively impact our overall financial results.

 If we fail to maintain effective internal control over financial reporting we may not be able to accurately or timely report our financial condition or results of operations.

 In connection with the audit of our consolidated financial statements for the year ended December 31, 2022, we identified a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

 While we believe we have now remediated the previously identified material weakness in our internal control over financial reporting, we cannot assure you that our remediation or other controls will continue to operate properly. If we are unable to maintain effective internal control over financial reporting, the accuracy and timing of our financial reporting may be adversely affected, we may incur significant expenses to remediate any material weaknesses, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports and applicable listing requirements, investors may lose confidence in our financial reporting, and the share price of our common stock may decline as a result. In addition, we could become subject to investigations by Nasdaq, the SEC or other regulatory authorities, which could require additional financial and management resources.

 Risks Related to Our Intellectual Property

 If we are unable to effectively protect our intellectual property, our business would be harmed.

 In addition to patent protection, we rely on trademark, copyright, trade secret protection and confidentiality agreements to protect intellectual property rights related to our proprietary technologies, both in the United States and in other countries. If we fail to protect our intellectual property, third parties may be able to compete more effectively against us and we may incur substantial litigation costs in our attempts to recover or restrict use of our intellectual property. As of December 31, 2024, we owned 20 issued U.S. patents and nine non-U.S. patents and had seven pending applications as well as registered marks in the United States and foreign countries. In addition to our patents and trademarks, we possess an array of unpatented proprietary technology and know-how, and we license intellectual property rights to and from third parties. The strength of patents in our field involves complex legal and scientific questions. In addition, patent law continuously evolves and might change the legal framework under which our patent claims would be interpreted and adjudicated in the future. Uncertainty created by these questions and potential legal changes means that our patents may provide only limited protection and may not adequately protect our rights or permit us to gain or keep any competitive advantage. In addition, competitors could purchase our products and attempt by reverse engineering to replicate some or all of the competitive advantages

 we derive from our development efforts, willfully infringe our intellectual property rights, design around our protected technology or develop their own competitive technologies that fall outside of the protections provided by our intellectual property rights. If our intellectual property, including licensed intellectual property, does not adequately protect our market position against competitors' products and methods, our competitive position could be adversely affected, as could our business.

 Further, if we are unable to prevent unauthorized disclosure of our non-patented intellectual property, and there is no guarantee that we will have any such enforceable trade secret protection, we may not be able to establish or maintain a competitive advantage. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad.

 We may not be successful in our currently pending or future patent applications, and even if such applications are successful, we cannot guarantee that the resulting patents will sufficiently protect our products and proprietary technology.

 We cannot assure you that any of our currently pending or future patent applications will result in issued patents with claims that adequately cover our products and technologies in the United States or in other foreign countries, and we cannot predict how long it will take for such patents to be issued. Further, issuance of a patent is not conclusive as to its inventorship or scope, and there is no guarantee that our issued patents will include claims that are sufficiently broad to cover our technologies or to provide meaningful protection from our competitors. Further, we cannot be certain that all relevant prior art relating to our patents and patent applications has been identified. Accordingly, there may be prior art that can invalidate our issued patents or prevent a patent from issuing from a pending patent application, or will preclude our ability to obtain patent claims that have a scope broad enough to provide meaningful protection from our competitors.

 Even if patents do successfully issue and even if such patents cover our products and technologies, we cannot assure you that other parties will not challenge the validity, enforceability or scope of such issued patents in the United States and in foreign countries, including by proceedings such as reexamination, inter-partes review, interference, opposition, or other patent office or court proceedings. The strength of patents in our field involves complex legal and scientific questions. Moreover, we cannot assure you that if such patents were challenged in court or before a regulatory agency that the patent claims will be held valid, enforceable, to be sufficiently broad to cover our technologies or to provide meaningful protection from our competitors. Nor can we assure you that the court or agency will uphold our ownership rights in such patents. Accordingly, we cannot guarantee that we will be successful in defending challenges made against our patents and patent applications. Any successful third-party challenge to our patents could result in the unenforceability or invalidity of such patents, or narrowing of claim scope, such that we could be deprived of patent protection necessary for the successful commercialization of our products and technologies, which could adversely affect our business.

 Furthermore, even if they are unchallenged, our patents and patent applications may not adequately protect our inventions, provide exclusivity for our products and technologies or prevent others from designing around our claims. Others may independently develop similar or alternative products and technologies or duplicate any of our products and technologies. These products and technologies may not be covered by claims of issued patents for which we are the right holder. Any of these outcomes could impair our ability to prevent competition from third parties, which may have an adverse impact on our business.

 Further, if we encounter delays in regulatory approvals, the period of time during which we could market a product under patent protection could be reduced. Since patent applications in the United States and most other countries are confidential for a period of time after filing, and some remain so until issued, we cannot be certain that we were the first to make the inventions covered by our pending patent applications, or that we were the first to file any patent application related to a product candidate. Furthermore, if third parties have filed such patent applications, interference or derivation proceedings in the United States can be initiated by a third party to determine who has the right to the subject matter covered by the claims of our patent applications and/or patents. We may not prevail in such proceedings. In addition, patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited.

 We may become involved in lawsuits to protect or enforce our patents or other intellectual property, which could be expensive and time consuming.

 Third parties may infringe or misappropriate our intellectual property, including our existing patents and patent claims that may be allowed in the future. As a result, we may be required to file infringement claims to stop third-party infringement or unauthorized use. Further, we may not be able to prevent misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the United States.

 If we file an infringement action against a third party, that party may challenge the scope, validity or enforceability of our patents, requiring us to engage in complex, lengthy and costly litigation or other proceedings. Such litigation and administrative proceedings could result in revocation of our patents or amendment of our patent claims such that they no longer cover our products. They may also put our pending patent applications at risk of not issuing or issuing with limited and potentially inadequate scope to cover our product candidates. The outcome following legal assertions of invalidity and unenforceability is unpredictable.

 Enforcing our intellectual property rights through litigation is very expensive and time-consuming. Some of our competitors may be able to sustain the costs of litigation more effectively than we can because of greater financial resources. Patent litigation and other proceedings may also absorb significant management time and reduce employee productivity. Furthermore, because of the substantial amount of discovery required in connection with U.S. intellectual property litigation or administrative proceedings, there is a risk that some of our confidential information could be compromised by disclosure. The occurrence of any of the foregoing could have a material adverse effect on our business, financial condition or results of operations.

 We could face claims that our proprietary technologies infringe on the intellectual property rights of others.

 Due to the significant number of U.S. and foreign patents issued to, and other intellectual property rights owned by, entities operating in the industry in which we operate, we believe that there is a risk of litigation arising from allegations of infringement of these patents and other rights. Third parties may assert infringement or other intellectual property claims against us, our licensees, or our customers.

 In addition, patent applications in the United States and many foreign jurisdictions are typically not published until 18 months after the earliest filing date for which a benefit is claimed. For this reason, and because publications in the scientific literature often lag behind actual discoveries, despite our best efforts we cannot be certain that others have not filed patent applications for technology covered by our issued patents or our pending applications or that we were the first to invent the technology. Another party may have filed or may in the future file patent applications covering our products or technology similar to ours. If another party has filed a U.S. patent application on inventions similar to ours, we may have to participate in an interference proceeding declared by the U.S. Patent and Trademark Office to determine priority of invention in the United States, or a derivation proceeding to determine rights to the relevant claimed subject matter. The costs of these proceedings could be substantial, and it is possible that such efforts would be unsuccessful if the other party had independently arrived at the same or similar invention prior to our own invention, or had filed applications directed to such applications before us, resulting in a loss of our U.S. patent position with respect to such inventions.

 We may have to pay substantial damages, including treble damages, for past infringement if it is ultimately determined that our products infringe on a third party's proprietary rights. In addition, even if such claims are without merit, defending a lawsuit may result in substantial expense to us and divert the efforts of our technical and management personnel. We may also be subject to significant damages or injunctions against development and sale of some or all of our products. Furthermore, claims of intellectual property infringement may require us to enter into royalty or license agreements with third parties, and we may be unable to obtain royalty or license agreements on commercially acceptable terms, if at all.

 We may be subject to claims by third parties asserting that our employees have misappropriated their intellectual property, or claiming ownership of what we regard as our own intellectual property.

 Many of our employees were previously employed at universities or other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that these

 employees or we have used or disclosed others' intellectual property, including trade secrets or other proprietary information, of any such employee's former employer. Litigation may be necessary to defend against these claims.

 In addition, while it is our policy to require our employees and contractors who may be involved in the development of intellectual property in the performance of their work to execute agreements assigning such intellectual property to us, we may be unsuccessful in executing an enforceable agreement with each party who in fact develops intellectual property that we regard as our own. Relevant assignment agreements may not be self-executing or may be breached, and we may be forced to bring claims against third parties, or defend claims they may bring against us, to determine the ownership of what we regard as our intellectual property.

 If we fail in prosecuting or defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in prosecuting or defending against such claims, litigation could result in substantial costs and be a distraction to management.

 Risks Related to Our Research and Development Activities

 We have made and intend to make significant additional investments in research and development, but there is no guarantee that any of these investments will ultimately result in commercial products that will generate revenues.

 The Accelerate Pheno system integrates several of our component products, systems and processes. We have dedicated significant resources on research and development activities into the Accelerate Pheno, Accelerate Arc and Accelerate WAVE systems, and we intend to spend significantly more on research and development activities, including for such systems. There can also be no assurance that we will be able to develop additional types of tests and instruments in the future nor whether these will result in commercial products that will generate revenues.

 We have a single research and development facility and we may be unable to continue to conduct our research and development activities if we lose this facility. If our facility or our equipment were damaged or destroyed, or if we experience a significant disruption in our operations for any reason, our ability to continue to operate our business could be materially harmed.

 We currently conduct all of our research and development and product development activities, other than those outsourced to third party providers, in our Tucson, Arizona facility. If this facility were to be damaged, destroyed or otherwise unable to operate, whether due to fire, floods, storms, tornadoes, other natural disasters, employee malfeasance, terrorist acts, power outages or otherwise, or if our business is disrupted for any other reason, including due to health epidemics, pandemics or outbreaks of communicable diseases, we may not be able to continue the development of future products or test our products as promptly as our potential customers expect, or possibly not at all, and we would have no other means of conducting such activities until we were able to restore such capabilities at the current facility or develop an alternative facility. Further, in such an event, we may lose revenue and significant time during which we might otherwise have conducted research and development and product development activities and, we may not be able to maintain our relationships with our licensees or customers.

 The manufacture of components of our products involves complex processes, sophisticated equipment and strict adherence to specifications and quality systems procedures. Any unforeseen manufacturing problems, such as contamination of our facility, equipment malfunction or failure to strictly follow procedures or meet specifications, could result in delays or shortfalls in the production of our products. Identifying and resolving the cause of any manufacturing issues could require substantial time and resources. If we are unable to keep up with future demand for our products by successfully manufacturing and shipping our products in a timely manner, our revenue growth could be impaired and market acceptance of our product candidates could be adversely affected.

 While we carry a nominal amount of business interruption insurance to cover lost revenue and profits, this insurance does not cover all possible situations. If we have underestimated our insurance needs with respect to an interruption, or if an interruption is not subject to coverage under our insurance policies, we may not be able to cover our losses. In addition, our business interruption insurance would not compensate us for the loss of opportunity and potential adverse impact on relations with our licensees or customers.

 We use hazardous materials in some of our research, development and manufacturing processes and face the accompanying risks and regulations governing environmental safety.

 Our operations are subject to complex and stringent environmental, health, safety and other governmental laws and regulations that both public officials and private individuals may seek to enforce. In particular, our research activities sometimes involve the controlled use of various hazardous materials. Although we believe that our safety procedures for handling and disposing of such materials are in material compliance with the standards prescribed by state and federal regulations, the risk of accidental contamination or injury from these materials cannot be completely eliminated, and we may not be in compliance with these regulations. In addition, existing laws and regulations may also be revised or reinterpreted, or new laws and regulations may become applicable to us, whether retroactively or prospectively, causing us to incur additional compliance costs and/or change the manner in which we operate. We could be held liable for any damages that might result from any accident or release involving hazardous materials.

 Risks Related to Government Regulation

 Legislative and Administrative Action May Have an Adverse Effect on Our Company

 Political, economic and regulatory influences are subjecting the health care industry in the U.S. to fundamental change. We cannot predict what other legislation relating to our business or to the health care industry may be enacted, including legislation relating to third-party reimbursement, or what effect such legislation may have on our business, prospects, operating results and financial condition. We expect federal and state legislators to continue to review and assess alternative health care delivery and payment systems, and possibly adopt legislation affecting further changes in the health care delivery system. Such laws may contain provisions that may change the operating environment for hospitals and managed care organizations. Health care industry participants may react to such legislation by curtailing or deferring expenditures and initiatives, including those relating to our products. Future legislation could result in modifications to the existing public and private health care insurance systems that would have a material adverse effect on the reimbursement policies discussed above. If enacted and implemented, any measures to restrict health care spending could result in decreased revenue from our products and decrease potential returns from our research and development initiatives. Furthermore, we may not be able to successfully neutralize any lobbying efforts against any initiatives we may have with governmental agencies.

 We and our suppliers, contract manufacturers and customers are subject to various governmental laws and regulations, and we may incur significant expenses to comply with, and experience delays in our product commercialization as a result of, these laws and regulations.

 Our operations are affected by various state, federal, and international healthcare, environmental, anti-corruption, fraud and abuse (including anti-kickback and false claims laws), privacy, and employment laws as well as international political sanctions. Violations of these laws and sanctions can result in criminal or civil penalties, including substantial fines and, in some cases, exclusion from participation in federal health care programs such as Medicare and Medicaid. In some cases, the violation of such laws could potentially lead to individual liability and imprisonment.

 We are also subject to extensive regulation by the FDA pursuant to the FDCA, by comparable agencies in foreign countries and by other regulatory agencies and governing bodies. Following the introduction of a product, these and other government agencies will periodically review our manufacturing processes, product performance and compliance with applicable requirements.

 We are also subject to various U.S. healthcare related laws regulating sales, contracting, marketing, and other business arrangements and the use and disclosure of individually identifiable health information. These include but are not limited to:

 • The federal Anti-Kickback Statute, a criminal law, which prohibits persons and entities from knowingly and willfully offering, paying, providing, soliciting, or receiving any remuneration, directly or indirectly, in cash or in kind, in exchange for or to induce or reward the referral of an individual, or the purchasing, leasing, ordering, recommending, furnishing or arranging for a good or service, for which payment may be made under a federal health care program, such as Medicare or Medicaid. A person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. Violations of the federal Anti-Kickback Statute can result in significant civil monetary penalties and criminal

 fines, as well as imprisonment and exclusion from participation in federal healthcare programs.
 • The federal False Claims Act, which imposes significant civil penalties, treble damages and potential exclusion from participation in federal healthcare programs against any person or entity that, among other things, knowingly presents, or causes to be presented, to the federal government claims for payment that are false or fraudulent or for making a false record or statement material to an obligation to pay the federal government or for knowingly and improperly avoiding, decreasing or concealing an obligation to pay money to the federal government Further, a violation of the federal Anti-Kickback Statute can serve as a basis for liability under the federal civil False Claims Act. The qui tam provisions of the False Claims Act allow private individuals to bring actions on behalf of the federal government and to share in any monetary recovery. There is also the federal Criminal False Claims Act, which is similar to the federal Civil False Claims Act and imposes criminal liability on those that make or present a false, fictitious or fraudulent claim to the federal government.
 • The federal Stark law, which prohibits physicians from referring patients to receive "designated health services" payable by Medicare or Medicaid from entities with which the physician or an immediate family member has a financial relationship, unless an exception applies. Financial relationships include both ownership/investment interests and compensation arrangements. Violation of the federal Stark law can result in significant civil monetary penalties and exclusion from participation in the federal healthcare programs.
 • The Eliminating Kickbacks in Recovery Act, which makes it a federal crime to knowingly and willfully solicit or receive any remuneration (including kickbacks, bribes, or rebates) in return for referring a patient to a recovery home, clinical treatment facility, or laboratory where the services are covered by a "health care benefit program," which includes private payers, or pay or offer any remuneration to induce such a referral or in exchange for an individual using the services of a recovery home, clinical treatment facility, or laboratory. Violations of the law may result in penalties per occurrence and imprisonment.
 • Federal criminal statutes created by HIPAA impose criminal liability for, among other things, knowingly and willfully (i) executing (or attempting to execute) a scheme to defraud any health care benefit program, including private payers, or (ii) falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for items or services under a health care benefit program.
 • HIPAA, as amended by HITECH, which also restricts the use and disclosure of protected health information, mandates the adoption of standards relating to the privacy and security of protected health information, and requires us to report certain security breaches to health care provider customers with respect to such information where we are acting as a HIPAA business associate to that customer.
 • The federal Physician Payment Sunshine Act, which requires applicable manufacturers of certain medical devices that may be reimbursed by Medicare, Medicaid, or CHIP, among others, to annually track and report payments or other transfers of value provided to U.S. licensed physicians, physician assistants, nurse practitioners, clinical nurse specialists, certified nurse anesthetists, anesthesiologist assistants and certified nurse-midwives, and U.S. teaching hospitals as well as certain ownership and investment interest held in the manufacturer by physicians and their immediate family members.

 Similar requirements have been adopted by many states and foreign countries. Violations of any of these laws can lead to additional legal risk such as risk of plaintiff class actions, state attorney general actions, and investigations by the FTC, among others.

 Failure to comply with applicable requirements, or later discovery of previously unknown problems with our products or manufacturing processes, including our failure or the failure of one of our contract manufacturers to take satisfactory corrective action in response to an adverse inspection, can result in, among other things:

 • administrative or judicially imposed sanctions;
 • injunctions or the imposition of civil penalties;
 • recall or seizure of our products;
 • corrective field actions for our products;
 • submission of reports to FDA or other regulatory authorities;
 • total or partial suspension of production or distribution;
 • withdrawal or suspension of marketing clearances or approvals;
 • clinical holds for investigations;
 • untitled letters or warning letters;
 • refusal to permit the import or export of our products;
 • criminal prosecution; and

 • exclusion or debarment from participation in federal health care programs such as Medicare and Medicaid.

 Any of these actions, in combination or alone, could prevent us from marketing, distributing and selling our products.

 In addition, we have developed and configured our business, and we intend to market our products, to meet customer needs created by these various laws and regulations. Any significant change in these regulations could reduce demand for our products. New legislation could also be enacted, and/or governmental agencies may also impose new requirements under existing laws, regarding registration, labeling or prohibited materials that may require us to modify or re-register, or seek new approvals or clearances for, products already on the market, may otherwise adversely impact our ability to market our products, or may otherwise reduce demand for our products. If materials used in our products become unavailable because of new governmental regulations, substitute materials may be less effective and may require significant cost to incorporate in our product.

 In addition, a product defect or regulatory violation could lead to a government-mandated or voluntary recall by us. We believe that the FDA would request that we initiate a voluntary recall if a product was defective or presented a risk of injury or gross deception. Regulatory agencies in other countries have similar authority to recall devices because of material deficiencies or defects in design or manufacture that could endanger health. Any recall would divert management attention and financial resources, could cause the price of our shares of common stock to decline, expose us to product liability or other claims (including contractual claims from parties to whom we sold products) and harm our reputation with customers.

 The use of our diagnostic products by our customers is also affected by CLIA and related federal and state regulations that provide for regulation of laboratory testing. CLIA is intended to ensure the quality and reliability of clinical laboratories in the United States by mandating specific standards in the areas of personnel qualifications, administration, participation in proficiency testing, patient test management, quality assurance, quality control and inspections. Current or future CLIA requirements or the promulgation of additional regulations affecting laboratory testing may prevent some laboratories, hospitals, providers or other customers with laboratories from using some or all of our diagnostic products.

 Maintaining adequate sales of our product may depend on the availability of adequate reimbursement to our customers from third-party payers, including government programs such as Medicare and Medicaid, private insurance plans, and managed care programs.

 Maintaining and growing sales of our approved products depends in part on the availability of adequate coverage and reimbursement of our products by third-party payers, including government programs such as Medicare and Medicaid, private insurance plans and managed care programs. Hospitals, clinical laboratories and other healthcare provider customers that may purchase our products generally bill various third-party payers to reimburse all or a portion of the costs and fees associated with diagnostic tests, including the cost of the purchase of our products. We currently expect that all of our diagnostic tests will be performed in a hospital inpatient setting, where governmental payers, such as Medicare, generally reimburse hospitals a single bundled payment that is based on the patient's diagnosis under the MS-DRG classification system for all items and services provided to the patient during a single hospitalization, regardless of whether our diagnostic tests are performed during such hospitalization. As a result, our customers' access to adequate reimbursement by government and private insurance plans is central to the acceptance of our products. We may be unable to sell our approved products on a profitable basis if third-party payers refuse to cover our products or reduce their current levels of reimbursement, or if our costs of production increases faster than increases in reimbursement levels.

 Additionally, third-party payers are increasingly reducing reimbursement for medical products and services. In addition, the U.S. government, state legislatures, and foreign governments have and may continue to implement cost-containment measures and more restrictive policies, including price controls and restrictions on reimbursement. Government authorities and third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular products. Further, the Budget Control Act of 2011 (the "Budget Control Act") established a process to reduce federal budget deficits through an automatic "sequestration" process if deficit reductions targets are not otherwise reached. Under the terms of the Budget Control Act, sequestration imposes cuts to a wide range of federal programs, including Medicare, which is subject to a two percent cut. The Bipartisan Budget Act of 2013 extended the two percent sequestration cut for Medicare through fiscal year 2023, and a bill signed by President Obama on February 15, 2014 further extended this cut for an additional year, through fiscal year 2024. The Bipartisan Budget Act of 2015, approved in November 2015, extended sequestration an

 additional year to 2025, Medicare reimbursements were lowered, and other changes were made to compliance measures. The Bipartisan Budget Act of 2019 signed by President Trump in August 2019 also extended sequestration for another two years to fiscal year 2029. Subsequent legislation extended sequestration through fiscal year 2031 for non-Medicare benefit payment spending and through fiscal year 2032 for Medicare benefit payments. The Coronavirus Aid, Relief, and Economic Security ("CARES") Act, signed into law in March 2020, included critical relief from sequestration cuts as it applies to Medicare payments, exempting Medicare from the effects of sequestration from May 1, 2020, through March 31, 2022. Cuts of 1% were imposed from April 1 through June 30, 2022. As of July 1, 2022, cuts of two percent were reimposed and are set to remain in effect until 2031 unless additional Congressional action is taken. To offset the temporary suspension during the COVID-19 pandemic, in 2030, the sequestration will be 2.25% for the first half of the year, and 3% in the second half of the year.

 While we cannot predict whether third-party reimbursement to our customers will be adequate, cost-containment measures and similar efforts by third-party payers, including government programs such as Medicare and Medicaid, could substantially impact the sales of our products and potentially limit our net revenue and results.

 We may be adversely affected by healthcare policy changes, including additional healthcare reform and changes in managed healthcare.

 Healthcare reform and the growth of managed care organizations have been considerable forces in the medical diagnostics industry and in recent political discussions. These forces have placed, and are expected to continue to place, constraints on the levels of overall pricing for healthcare products and services as well as the coverage available by public and private insurance and thus, could have a material adverse effect on the future profit margins of our products or the amounts that we are able to receive from third parties for the licensing of our products. Changes in the United States healthcare market could also force us to alter our approach to selling, marketing, distributing and servicing our products and customer base. In and outside the United States, changes to government reimbursement policies could reduce the funding that healthcare service providers have available for diagnostic product expenditures, which could have a material adverse impact on the use of the products we are developing and our future sales, license and royalty fees and profit margin.

 For example, the ACA requires CMS to reduce payments to hospitals reimbursed under Medicare's Inpatient Prospective Payment System ("IPPS") that have excess readmissions. This and other applicable requirements set forth under the ACA and its current and future implementing regulations may significantly increase our costs, and/or reduce our customer's ability to obtain adequate reimbursement for tests performed with our products, which could adversely affect our business and financial condition. In addition to direct impacts from reimbursement cuts, sales of our products could be negatively impacted if reimbursement cuts reduce microbiology budgets. While the ACA is intended to expand health insurance coverage to uninsured persons in the United States, other elements of this legislation that are still being developed and refined, such as Medicare provisions aimed at improving quality and decreasing costs, comparative effectiveness research, an independent payment advisory board, and pilot programs to evaluate alternative payment methodologies, make it difficult to determine the overall impact on sales of our products. In addition to uncertainty regarding the impact of implementation of the ACA, there are some continued legal challenges to the ACA that, if successful, could call into question the legitimacy of the ACA and its future applicability.

 In recent years, other legislative, regulatory, and political changes aimed at regulating healthcare delivery in general and clinical laboratory tests in particular have been proposed and adopted in the United States. Reimbursement for the laboratory industry is under significant pressure. In January 2015, HHS announced a plan to shift the Medicare program and the healthcare system at large, toward paying providers based on quality, rather than the quantity of care provided to patients. In 2017, Medicare's clinical laboratory reimbursement system became tied to private market rates with the start of the effective period for the Protecting Access to Medicare Act of 2014 ("PAMA"), changing the payment environment for clinical laboratory tests. The measures implemented by PAMA and ACA regulations can result in reduced prices, added costs, and decreased test utilization for our customers, although the full impact on our business of the ACA, changes to the IPPS, PAMA, and other applicable laws, regulations, and policies is uncertain.

 We cannot predict whether future healthcare initiatives will be implemented at the federal or state level or in countries outside of the United States in which we may do business, or the effect of any future legislation or regulation will have on our industry generally, our ability to successfully commercialize our products, and our overall business operations. Continued changes in healthcare policy could substantially impact the sales of our tests,

 increase costs and divert management's attention from our business. For example, any expansion in the government's regulation of the United States healthcare system could result in decreased profits to us, lower reimbursements to our customers for laboratory testing or reduced medical procedure volumes.

 The regulatory processes applicable to our products and operations are expensive, time-consuming, and uncertain and may prevent us from obtaining required authorizations for the commercialization of our products.

 Our products are regulated as medical devices by the FDA and comparable agencies of other countries. In particular, the FDCA and implementing FDA regulations govern activities for devices such as design, development, testing, manufacturing, storage, distribution, labeling, registration and listing, premarket clearance or approval, advertising, promotion, sales, and reporting for devices, including reporting of certain malfunctions, deaths, and injuries associated with the device, and reporting of certain recalls and corrective field actions. Some of our products, depending on their intended use, will require approval of a PMA application or clearance of a 510(k) notification, or granting of a request for de novo classification from the FDA prior to marketing. The FDA has committed to review most 510(k) decisions within 90 days, but the review may be delayed due to requests for additional information. A decision may take significantly longer, and clearance is never assured. The PMA process is much more costly, lengthy and uncertain. The FDA has committed to review most PMAs within 180 days where an advisory panel is not required and within 320 days where an advisory panel is required, but the review may be delayed due to requests for additional information. A decision may take significantly longer, and approval is never assured. In the 510(k) clearance process, the FDA must determine that a proposed device is "substantially equivalent" to a device legally on the market, known as a "predicate" device, with respect to intended use, technology and safety and effectiveness, in order to clear the proposed device for marketing. Clinical data is sometimes required to support substantial equivalence. The PMA pathway requires an applicant to demonstrate the safety and effectiveness of the device based on extensive data, including technical, preclinical, clinical trial, manufacturing and labeling data. The PMA process is typically required for Class III devices that are deemed to pose the greatest risk, including devices for which general controls would be insufficient, and special controls cannot be developed, to provide a reasonable assurance of safety and effectiveness of the device, such as life-sustaining, life-supporting or implantable devices, or devices that otherwise present a potential unreasonable risk of illness or injury. However, some devices are automatically classified as Class III and subject to the PMA pathway regardless of the level of risk they pose, because there is no legally marketed predicate device to which the proposed device may demonstrate substantial equivalency. Manufacturers of these devices may request that the FDA review such devices in accordance with the de novo classification procedure, which allows a manufacturer whose novel device would otherwise require the submission and approval of a PMA prior to marketing to request down-classification of the device on the basis that the device presents low or moderate risk. If the FDA agrees with the down-classification, the applicant will then receive authorization to market the device. This device type can then be used as a predicate device for future 510(k) submissions.

 The FDA can delay, limit or deny clearance or approval of a device for many reasons, including:

 • we may not be able to demonstrate to the FDA's satisfaction that our product candidates provide a reasonable assurance of safety and effectiveness for their intended uses, or that our product candidates are substantially equivalent to a predicate device;
 • the data from our pre-clinical studies and clinical trials may be insufficient to support clearance or approval, or de novo classification, where required; and
 • the manufacturing process or facilities we or our contract manufacturers use may not meet applicable requirements.

 With respect to those future products where a PMA is not required, we cannot assure you that we will be able to obtain 510(k) clearances or de novo classification with respect to those products. The process of obtaining regulatory clearances or approvals, or completing the de novo classification process, to market a medical device can be costly and time consuming, and we may not be able to successfully obtain pre-market reviews on a timely basis, if at all. Further, even if we were to obtain regulatory clearance, approval or de novo classification, it may not be for the uses we believe are important or commercially attractive, in which case we would not be permitted to market our product for those important or commercially attractive uses that were not cleared, approved or de novo classified.

 Clinical trial data is typically required to support a PMA or de novo classification request and is sometimes required for a 510(k) pre-market notification. Although many 510(k) pre-market notifications are cleared without

 clinical data, in some cases, the FDA requires clinical data to support a demonstration of substantial equivalence. Clinical trials are expensive and time-consuming. In addition, the commencement or completion of any clinical trials may be delayed or halted for any number of reasons, including product performance, changes in intended use, changes in medical practice and the opinion of evaluator Institutional Review Boards.

 The FDA has also undertaken initiatives related to enhancement of the 510(k) review process and has initiated changes to the regulation of laboratory developed tests ("LDTs"). In particular, on April 29, 2024, the FDA announced its Final Rule on LDTs, which makes clear that LDTs are now considered to be regulated as medical devices, and phases out its historical exercise of enforcement discretion for such tests. The Final Rule indicates that laboratories offering LDTs would be expected to come into compliance with FDA regulation of medical devices over a prescribed period of time. The Final Rule was published on May 6, 2024 and become effective on July 5, 2024. We continue to monitor these developments and analyze how they will impact the clearance approval and classification of our products, as well as the demand for our products by customers. These and other actions proposed by the FDA's Center for Devices and Radiological Health ("CDRH") could result in significant changes to the 510(k) process, which could complicate the clearance, approval and de novo classification processes, although we cannot predict the effect of such changes and cannot ascertain if such changes will have a substantive impact on the clearance, approval or de novo classification of our products. If we fail to adequately respond to the increased scrutiny and changes to the 510(k) submission process, our business may be adversely impacted.

 Failure to comply with the applicable requirements can result in, among other things, untitled letters, warning letters, administrative or judicially imposed sanctions such as injunctions, civil penalties, recall or seizure of products, total or partial suspension of production, refusal to grant premarket clearance, PMA approval or de novo classification for devices, withdrawal of marketing clearances or approvals, or criminal prosecution. With regard to products for which we seek 510(k) clearance, PMA approval or de novo classification from the FDA, any failure or material delay to obtain such clearance, approval or de novo classification could harm our business. If the FDA were to disagree with our regulatory assessment and conclude that approval, clearance or de novo classification is necessary to market the devices, we could be forced to cease marketing the products and seek approval, clearance or de novo classification before continuing to market such devices. Once clearance, approval or de novo classification has been obtained for a product, there is an obligation to ensure that all applicable FDA and other regulatory requirements continue to be met.

 In addition, it is possible that the current regulatory framework could change or additional laws or regulations could arise at any stage during our product development or marketing, which may adversely affect our ability to obtain or maintain clearance, approval or de novo classification of our products. Any delay in, or failure to receive or maintain, clearance, approval or de novo classification for our product candidates could prevent us from generating revenue from these product candidates. Additionally, the FDA and other regulatory authorities have broad enforcement powers. Regulatory enforcement or inquiries, or other increased scrutiny on us, could affect the perceived safety and efficacy of our product candidates and dissuade our customers from using our product candidates, if and when they are authorized for marketing.

 Our manufacturing facility located in Tucson, Arizona, where we assemble and produce our products, may be subject to regulatory inspections by the FDA and other federal and state and foreign regulatory agencies. For example, this facility is subject to QSRs of the FDA and is subject to annual inspection and licensing by the State of Arizona. If we fail to maintain this facility in accordance with the QSR requirements, international quality standards or other regulatory requirements, our manufacturing process could be suspended or terminated, which would prevent us from being able to provide products to our customers in a timely fashion.

 Sales of our diagnostic product candidates outside the United States are subject to foreign regulatory requirements governing clinical studies, vigilance reporting, marketing approval, manufacturing, product licensing, pricing and reimbursement. These regulatory requirements vary greatly from country to country. As a result, the time required to obtain approvals outside the United States may differ from that required to obtain FDA marketing authorization from the FDA, and we may not be able to obtain foreign regulatory approvals on a timely basis or at all. Marketing authorization from the FDA does not ensure approval by regulatory authorities in other countries, and approval by one foreign regulatory authority does not ensure clearance or approval by regulatory authorities in other countries or by the FDA. Foreign regulatory authorities could require additional testing. Failure to comply with foreign regulatory requirements, or to obtain required clearances or approvals, could impair our ability to commercialize our diagnostic product candidates outside of the United States.

 Global health crises may divert regulatory resources and attention away from approval processes for our products. This could materially lengthen the regulatory approval process of new products, which would delay expected commercialization of such new products.

 Modifications to our products, if cleared or approved, may require new 510(k) clearances or pre-market approvals, or may require us to cease marketing or recall the modified products until clearances are obtained.

 Any modification to a 510(k)-cleared or de novo classified device that could significantly affect its safety or effectiveness, or that would constitute a major change in its intended use, design or manufacture, requires a new 510(k) clearance, unless a predetermined change control plans ("PCCP") for the device has been cleared. If a PCCP has been cleared for the device, then the manufacturer may make changes to the device consistent with the cleared PCCP without submitting a new 510(k), even though such changes would typically require 510(k) clearance. If the modification would result in the device becoming a different type of device, including a novel device or a Class III device, then a de novo classification request or PMA, rather than a new 510(k), may be required. Similarly, any modification to a PMA-approved device that affects the safety or effectiveness of the device, including significant modifications to the manufacturing process, labeling of the product, or design of the device, requires a PMA supplement or new PMA, unless a PCCP has been approved for the device. If a PCCP has been approved for a PMA-approved device, then changes may be made to the device consistent with the approved PCCP without submitting a PMA supplement, even though such changes would typically require a PMA supplement. The FDA requires each manufacturer to make the determination initially whether a new 510(k), de novo classification request, or PMA is required for a modification to a device, or whether the modification may be documented without further FDA premarket review, but the FDA may review any manufacturer's decision. The FDA may not agree with our decisions regarding whether new clearances, de novo classifications, or PMA approvals are necessary. If the FDA disagrees with our determination and requires us to submit new 510(k) notifications, de novo classifications, PMA supplements or PMAs for modifications to previously cleared, de novo classified, or approved products for which we conclude that new clearances, de novo classification, or approvals are unnecessary, we may be required to cease marketing or to recall the modified product until we obtain clearance or approval, and we may be subject to significant fines or penalties.

 Furthermore, the FDA's ongoing review of the 510(k) program may make it more difficult for us to make modifications to any products for which we obtain clearance or de novo classification, either by imposing more strict requirements on when a manufacturer must submit a new 510(k) for a modification to a previously cleared or de novo classified product, or by applying more onerous review criteria to such submissions. The practical impact of the FDA's continuing scrutiny of the 510(k) program remains unclear.

 We rely on third parties to conduct studies of our products that may be required by the FDA or other regulatory authorities, and those third parties may not perform satisfactorily.

 We rely on third parties, including clinical investigators, to conduct studies on our products. Our reliance on these third parties for clinical development activities will reduce our control over these activities. These third parties may not complete activities on schedule or conduct studies in accordance with regulatory requirements or our study design. If applicable, our reliance on third parties that we do not control will not relieve us of any applicable requirement to prepare, and ensure compliance with, various procedures required under good clinical practices. If these third parties do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines, if the third parties need to be replaced or if the quality or accuracy of the data they obtain is compromised due to their failure to adhere to our clinical protocols or regulatory requirements or for other reasons, our studies may be extended, delayed, suspended or terminated, and we may not be able to obtain marketing authorization from the FDA or other regulatory authorities for our products.

 A recall of our products, either voluntarily or at the direction of the FDA, or the discovery of serious safety issues with our products that leads to corrective actions, could have a significant adverse impact on us.

 The FDA and similar foreign governmental authorities have the authority to require the recall of commercialized products. In addition, manufacturers may, under their own initiative, recall a product for any reason, including if any material deficiency in a device is found. A government-mandated or voluntary recall by us or one of our distributors could occur as a result of an unacceptable risk to health, component failures, manufacturing errors, design or labeling defects or other deficiencies and issues. Under the FDA's medical device reporting regulations, we are required to report to the FDA any incident in which information reasonably suggests that our product may

 have caused or contributed to a death or serious injury or in which our product malfunctioned and, if the malfunction were to recur, such malfunction would likely cause or contribute to death or serious injury. Repeated product malfunctions may result in a voluntary or involuntary product recall. Recalls of any of our products would divert managerial and financial resources, have an adverse effect on our reputation, and may impair our ability to produce our products in a cost-effective and timely manner in order to meet our customers' demands. Additionally, under the FDA's regulations for corrections and removals, we are required to report to the FDA any field correction or other recall action that is initiated to reduce a risk to health, or to remedy a violation of the FDCA caused by the device which may present a risk to health. Depending on the corrective action we take to redress a product's deficiencies or defects, the FDA may require, or we may decide that we will need to obtain, new approvals, clearances or de novo classification for the device before we may market or distribute the corrected device. Seeking such approvals, clearances or de novo classification may delay our ability to replace the recalled devices in a timely manner. Moreover, if we do not adequately address problems associated with our devices, we may face additional regulatory enforcement action, including FDA untitled letters, warning letters, product seizure, injunctions, administrative penalties, or civil or criminal fines. We may also be required to bear other costs or take other actions that may have a negative impact on our sales as well as face significant adverse publicity or regulatory consequences, which could harm our ability to market our products in the future.

 Any adverse event involving our products could result in future voluntary corrective actions, such as recalls or customer notifications, or agency action, such as inspection, mandatory recall or other enforcement action. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, would require the dedication of our time and capital, distract management from operating our business and may harm our reputation.

 Risks Related to Our Common Stock

 Our common stock may be delisted from The Nasdaq Capital Market, which could have a material adverse effect on our business and financial condition and could make it more difficult for you to sell your shares.

 We are required to continually meet Nasdaq's listing requirements in order to maintain the listing of our common stock on The Nasdaq Capital Market. As described in a Current Report on Form 8-K filed with the SEC on January 30, 2025, we received written notice (the "Notice") from Nasdaq's Listing Qualifications Staff (the "Staff") on January 28, 2025 notifying us that for the last 30 consecutive business days prior to the date of the Notice, our Market Value of Listed Securities (as defined under Nasdaq rules) was below the minimum of $35 million required for continued listing on The Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(b)(2) (the "MVLS Requirement"). In accordance with Nasdaq Listing Rule 5810(c)(3)(C), Nasdaq has provided us with 180 calendar days, or until July 28, 2025 (the "Compliance Date"), to regain compliance with the MVLS Requirement. If, at any time before the Compliance Date, the market value of our common stock (calculated in accordance with Nasdaq rules) closes at $35 million or more for a minimum of ten consecutive business days, Nasdaq will provide written confirmation to us and close the matter.

 If we do not regain compliance with the MVLS Requirement prior to the Compliance Date, the Staff will provide written notification to us that our common stock will be subject to delisting. At that time, we may appeal the Staff's delisting determination to a Nasdaq Hearing Panel. We are evaluating potential actions to regain compliance with the MVLS Requirement and intend to actively monitor the market value of our common stock. We may also, if appropriate, consider other options to regain compliance with Nasdaq's continued listing standards. There can be no assurance that we will regain compliance with the MVLS Requirement or otherwise maintain compliance with any of the other Nasdaq listing requirements.

 Any delisting of our common stock from The Nasdaq Capital Market could adversely affect our ability to attract new investors, reduce the liquidity of our outstanding shares of common stock, reduce our ability to raise additional capital, reduce the price at which our common stock trades, result in negative publicity and increase the transaction costs inherent in trading such shares with overall negative effects for our stockholders. Additionally, a delisting of our common stock would be a "Fundamental Change" under the 5.00% Notes Indenture, which would trigger a right by the holders thereof to require us to repurchase the then outstanding 5.00% Notes. In such an event, we would likely need to seek financing to repurchase the 5.00% Notes, and there is no guarantee that such financing would be available or on terms acceptable to us. If noteholders demanded a repurchase of such 5.00% Notes and we were unable to finance the repurchase, or if we failed to deliver notice of the noteholders' right to repurchase, we would be in default under the 5.00% Notes Indenture. Such default would also constitute an event of default under the 16.00% Notes Indenture and the holders of the 16.00% Notes would have the right, but not the obligation, to declare all of the outstanding amounts owing thereunder due and payable as well. For additional information, see "Risks

 Related to Our Financial Condition, Liquidity and Indebtedness - We have substantial indebtedness, which could have important consequences to our business."

 We cannot assure you that our common stock, if delisted from The Nasdaq Capital Market, will be listed on another national securities exchange or quoted on an over-the-counter quotation system. In addition, delisting of our common stock could deter broker-dealers from making a market in or otherwise seeking or generating interest in our common stock and might deter certain institutions and persons from investing in our securities at all. For these reasons and others, delisting could adversely affect our business, financial condition and liquidity.

 We have significantly increased the total number of authorized shares of common stock under our certificate of incorporation, which could cause significant dilution.

 Our management believes the successful achievement of our business objectives may require additional financing through one or a combination of the issuance of common stock in public or private equity offerings, debt financings, exercise of common stock warrants, collaborations, licensing arrangements, grants and government funding and strategic alliances. To effectuate that, in May 2023, we sought and obtained authorization from stockholders to increase the total number of authorized shares of common stock under our certificate of incorporation by 250,000,000 for a total of 450,000,000 shares. Additionally, in July 2023, we completed a one-for-ten Reverse Stock Split resulting in a relative increase in the number of authorized and unissued shares of our common stock. The future issuance of all or part of our remaining authorized common stock may result in substantial dilution to our stockholders and may adversely affect the market price of our common stock.

 Future issuances or sales of shares of our common stock may depress the price of our shares and be dilutive to our existing stockholders.

 We cannot predict whether future issuances of shares of our common stock or the availability of shares for resale in the open market will decrease the market price per share of our common stock. Any sales by us or by our existing stockholders of a substantial number of shares of our common stock in the public market, or the perception that such sales might occur, may cause the market price of our shares to decline. The exercise of any outstanding options or warrants, vesting of outstanding restricted stock units ("RSUs"), the issuance of future equity awards to retain and incentivize employees, the issuance of our common stock upon the conversion or exchange of our convertible notes and any other issuances of our common stock could have an adverse effect on the market price of the shares of our common stock.

 To the extent that we raise additional funds through the issuance and sale of equity or convertible debt securities the issuance of such securities will result in dilution to our stockholders. Investors purchasing shares or other securities in the future may also have rights superior to existing stockholders. In addition, we have a significant number of options, warrants and RSUs outstanding. If the holders of these options, or warrants exercise, or the RSUs are settled upon vesting, our stockholders may incur further dilution.

 We are likely to require additional capital in the future, and you may incur dilution to your stock holdings.

 We have primarily relied upon capital from the sale of our securities to fund our operations. Although we have now commercialized the Accelerate Pheno system in the United States, Europe, and certain other regions, there can be no assurance that our commercialization efforts will be successful or that we will not continue to incur operating losses. We may require additional capital to continue to operate as a going concern in the near-term and may require additional capital in the future to expand our product offerings, expand our sales and marketing infrastructure, increase our manufacturing capacity, fund our operations, and continue our research and development activities. Our future funding requirements will depend on many factors, including:

 • our ability to address existing obligations, including the Notes;
 • our ability to obtain marketing authorization from the FDA or clearance from the FDA to market our product candidates;
 • market acceptance of our product candidates, if cleared;
 • the cost and timing of establishing sales, marketing and distribution capabilities;
 • the cost of our research and development activities;

 • the ability of healthcare providers to obtain coverage and adequate reimbursement by third-party payers for procedures using our products;
 • the cost and timing of marketing authorization or regulatory clearances;
 • the cost of goods associated with our product candidates;
 • the cost of customer disruptions due to supply disruptions;
 • the effect of competing technological and market developments; and
 • the extent to which we acquire or invest in businesses, products and technologies, including entering into licensing or collaboration arrangements for product candidates.

 If we require additional capital, we may attempt to raise it through a variety of strategies, including the issuance and sale of additional shares of our common stock. Issuances of additional shares of our common stock or preferred stock in the future, whether in connection with a rights offering, follow-on offering or otherwise, would dilute existing stockholders and may adversely affect the market price of our common stock.

 We cannot assure you that we will be able to obtain additional funds on acceptable terms, or at all. Debt financing, if available, may involve covenants restricting our operations or our ability to incur additional debt. Any debt or additional equity financing that we raise may contain terms that are not favorable to us or our stockholders. If we raise additional funds through collaboration and licensing arrangements with third parties, it may be necessary to relinquish some rights to our technologies or our products, or grant licenses on terms that are not favorable to us. If we are unable to raise adequate funds, we may have to liquidate some or all of our assets or delay, reduce the scope of or eliminate some or all of our product development.

 If we do not have, or are not able to obtain, sufficient funds, we may be required to delay additional product development or license to third parties the rights to commercialize our products or technologies that we would otherwise seek to commercialize ourselves. We also may have to reduce marketing, customer support or other resources devoted to our product candidates or cease operations. Any of these factors could harm our operating results.

 Our stock price has been volatile and may continue to be volatile and traded on low volumes.

 The trading price of our common stock has been, and is likely to continue to be, highly volatile. Factors that may contribute to volatility in the price of our common stock include, but are not limited to:

 • difficulties in resolving our continuing financial condition and our ability to obtain additional capital to meet our financial obligations;
 • low trading volume currently prevailing in the market for our shares;
 • concentration of our stock with one individual large shareholder who could decide to materially reduce his position;
 • the substantial current short interest in our stock;
 • our failure to meet applicable Nasdaq listing standards and the possible delisting of our common stock from Nasdaq;
 • adverse regulatory decisions, including failure to receive regulatory approvals for any of our product candidates;
 • our success in commercializing our product candidates, if and when approved;
 • the introduction of new products or product enhancements by us or others in our industry;
 • announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures, capital commitments or restructurings;
 • disputes or other developments with respect to our or others' intellectual property rights;
 • product liability claims or other litigation;
 • quarterly variations in our results of operations or those of others in our industry;
 • sales of large blocks of our common stock, including sales by our executive officers and directors;
 • changes in senior management or key personnel;
 • changes in laws or regulations which adversely affect our industry or us;
 • changes in earnings estimates or recommendations by securities analysts; and
 • changes in general market, economic, and political conditions in the U.S., and global economies or financial markets, including those resulting from natural disasters, terrorist attacks, acts of war, other geopolitical

 uncertainties, public health concerns (including health epidemics, pandemics or outbreaks of communicable diseases), and responses to such events.

 The market value of your investment in our common stock may rise or fall sharply at any time because of this volatility and also because of significant short positions that may be taken by investors from time to time in our common stock. During the year ended December 31, 2024, the sale price for our common stock ranged from $0.74 to $4.23 per share, and during the year ended December 31, 2023, the sale price for our common stock ranged from $3.92 to $10.30 per share. Share prices shown reflect the Company effected one-for-ten Reverse Stock Split which occurred on July 11, 2023. The market prices for securities of medical technology companies like ours historically have been highly volatile, and the market has experienced significant price and volume fluctuations that are unrelated to the operating performance of particular companies.

 In addition, in the past, following periods of volatility in the market price of a company's securities, securities class-action litigation has often been instituted against that company. Any lawsuit to which we are a party, with or without merit, may result in an unfavorable judgment. We also may decide to settle lawsuits on unfavorable terms. Any such negative outcome could result in payments of substantial damages or fines, damage to our reputation or adverse changes to our product offerings or business practices. Such litigation may also cause us to incur other substantial costs to defend such claims and divert management's attention and resources. Furthermore, negative public announcements of the results of hearings, motions or other interim proceedings or developments could have a negative effect on the market price of our common stock.

 The ownership of our common stock is highly concentrated.

 As of December 31, 2024, our directors and executive officers beneficially owned in the aggregate, approximately 39% of our outstanding common stock, including 33% beneficially owned, directly or indirectly, by our director, Jack Schuler. As a result, these stockholders will be able to affect the outcome of, or exert significant influence over, all matters requiring stockholder approval, including the election and removal of directors and any change in control. In particular, this concentration of ownership of our common stock could have the effect of delaying or preventing a change in control of us or otherwise discouraging or preventing a potential acquirer from attempting to obtain control of us. This, in turn, could have a negative effect on the market price of our common stock. It could also prevent our stockholders from realizing a premium over the market prices for their shares of common stock. Moreover, the interests of this concentration of ownership may not always coincide with our interests or the interests of other stockholders. The concentration of ownership also contributes to the low trading volume and volatility of our common stock. Certain of our major shareholders hold their shares in certificate form, further limiting trading volume.

 Provisions in our Amended and Restated Certificate of Incorporation (as amended, our "Charter"), our Amended and Restated Bylaws (as amended, our "Bylaws") and Delaware law may delay or prevent acquisition of our Company, which could adversely affect the value of our common stock.

 Provisions contained in our Charter and Bylaws, as well as provisions of the Delaware General Corporation Law ("DGCL"), could delay or make it more difficult to remove incumbent directors or for a third party to acquire us, even if a takeover would benefit our stockholders. For example, our board of directors may fill any vacancy on the board of directors, whether such vacancy occurs as a result of an increase in the number of directors or otherwise. Special meetings of the stockholders may be called only by the President, a Vice President, our board of directors or the holders of not less than one-tenth of all the shares entitled to vote at the meeting. Additionally, our board of directors has the authority to cause us to issue, without any further vote or action by the stockholders, up to 5.0 million shares of preferred stock, par value $0.001 per share, in one or more series, to fix the number of shares constituting such series and the designation of such series, the voting powers, if any, of the shares of such series, and the preferences and relative, participating, optional or other special rights, if any, and any qualifications, limitations or restrictions thereof, of the shares of such series. The issuance of shares of preferred stock may have the effect of delaying, deferring or preventing a change in control of our Company without further action by the stockholders, even where stockholders are offered a premium for their shares. Moreover, we are subject to the provisions of Section 203 of the DGCL, which prohibits a person who owns in excess of 15% of our outstanding voting stock from merging or combining with us for a period of three years after the date of the transaction in which the person acquired in excess of 15% of our outstanding voting stock, unless the merger or combination is approved in a prescribed manner.

 General Risk Factor

 Current macroeconomic conditions and the uncertain economic outlook may remain challenging for the foreseeable future.

 Global economic conditions, which have led to market disruptions and significant volatility in credit and capital markets, may remain challenging and uncertain for the foreseeable future, including inflation, global health crises, international wars and disputes, and disruptions to the banking system due to bank failures. These conditions not only limit our access to capital but also make it difficult for our customers, our vendors and us to accurately forecast and plan future business activities, and they could cause U.S. and foreign hospitals and other customers to slow spending on our products, which would delay and lengthen sales cycles. Some of our customers rely on government research grants to fund technology purchases. If negative trends in the economy affect the government's allocation of funds to research, there may be less grant funding available for certain of our customers to purchase technologies from us. Certain of our customers may face challenges gaining timely access to sufficient credit or may otherwise be faced with budget constraints, which could result in decreased purchases of our products or in an impairment of their ability to make timely payments to us. If our customers do not make timely payments to us, we may be required to assume greater credit risk relating to those customers and increase our allowance for credit losses, and our days sales outstanding would be negatively impacted. Although we maintain allowances for credit losses for estimated losses resulting from the inability of our customers to make required payments, we may not continue to experience the same loss rates that we have in the past.

 Item 1B. Unresolved Staff Comments

 Not applicable.

 Item 1C. Cybersecurity

 Risk Management and Strategy

 We recognize the importance of developing, implementing and maintaining robust cybersecurity measures to safeguard our information systems and protect the confidentiality, integrity, and availability of our data. As such, we have implemented cybersecurity programs designed to maintain compliance with applicable laws and regulations governing ethical business practices, including our relationships with suppliers, customers, and business partners.

 We maintain formal processes for our cybersecurity program and incident response procedures, which are updated at least annually. These processes include, among other things, detailed steps on how we assess cybersecurity risks, identify threats, and determine the materiality of cybersecurity incidents. These processes also designate certain roles within the company to execute these policies and certain leadership roles to manage material risk escalation. These processes endeavor to follow the National Institute of Standards and Technology (NIST) Cybersecurity Framework.

 Our Information Security team uses automated technology, third-party partners, and direct review of system indicators to monitor and implement the prevention, detection, mitigation, and remediation of cybersecurity incidents, and to stay current with the changing threat landscape. We also leverage encryption technologies and other measures to safeguard systems. We engage third parties as part of our cybersecurity program, including external security firms that provide security technology, conduct regular security audits, and conduct penetration testing.

 We also engage third-party service providers to assist with managing various other aspects of our business. We review SOC 1 and similar documentation from these third-party service providers at least annually to better understand the information security programs maintained by them.

 Our employees are responsible for complying with our data security standards and are required to complete annual training to understand the behaviors and technical requirements necessary to keep data secure.

 As of the date of this Form 10-K, we are not aware of any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially

 affect us, including our business strategy, results of operations, or financial condition. For additional information regarding cybersecurity-related risks we face, see Risk Factors - Risks Related to Our Business and Strategy-Breaches of our information technology systems could have a material adverse effect on our operations and potentially result in liability, depending on the type of breach and information compromised."

 Governance

 Cybersecurity is an important component of our enterprise risk management program. While our full board of directors (the "Board") has primary responsibility for risk oversight, the Board utilizes its committees, as appropriate, to monitor and address the risks that may be within the scope of a particular committee's expertise or charter and receives regular updates at Board meetings on committee activities.

 The Audit and Governance Committee has oversight over the adequacy of the Company's enterprise risk management and internal controls, including computerized information system controls and security, and regularly reviews our cybersecurity, including information technology ("IT") risks, controls, procedures, and plans to mitigate cybersecurity risks and respond to cybersecurity incidents. Due to the importance of cybersecurity, the full Board receives a report on at least annually from our IT Director, on, among other issues, our cybersecurity risks and threats, the status of IT projects, management's strategies to strengthen our IT systems, assessments of our cybersecurity program, third-party assessments and testing, our emerging cybersecurity threat landscape, and the review of our cybersecurity insurance policy. Updates are held more frequently with the Audit and Governance Committee as deemed appropriate for significant changes to the Company's IT systems or cybersecurity processes. Pursuant to our incident response procedures, material cybersecurity incidents are also reported to the Audit and Governance Committee upon a determination of materiality by our IT Director.

 Management is responsible for our day-to-day risk management activities. As cybersecurity risks arise, our IT Director executes our incident response procedures and communicates the appropriate details to management in alignment with the escalation steps set forth in such procedures.

 Our cybersecurity program is led by our IT Director, who is responsible for assessing and managing cybersecurity risks. He has more than 12 years of experience as a leader in both the medical and defense industries. As cybersecurity-centric manager our IT Director has also achieved high-level security clearance and held the title of Information System Security Officer for other organizations.

 Item 6. [Reserved]

 Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

 The following Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") summarizes our change in fiscal year financial condition, results of operations, recent developments, the significant factors affecting our results of operations, capital resources and liquidity, off-balance sheet arrangements, and contractual obligations, and discusses recent accounting pronouncements and our critical accounting policies and estimates. You should read the following discussion and analysis together with our financial statements, including the related notes, which are included in this Form 10-K. Certain information contained in the discussion and analysis set forth below and elsewhere in this report, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. See Part I, Item 1A, Risk Factors of this Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements in this report.

 Changes in Results of Operations: Comparison of fiscal years ended December 31, 2024 and 2023

 The Company has provided enhanced information in a tabular format which presents some of the captions presented on the statement of operations, less inventory write-downs and non-cash equity-based compensation expense. These figures are reconciled to the statement of operations and are intended to add additional clarity on the operating performance of the business. The Company believes providing such figures less inventory write-downs and non-cash equity-based compensation expense provides helpful information for investors in understanding and evaluating our operating results in the same manner as our management and our board of directors.

 During the year ended December 31, 2024, net sales decreased primarily due to lower sales of Accelerate Pheno instruments compared to the year ended December 31, 2023, as fewer new contracts were signed for new Accelerate Pheno instrument placements in the current year. This decrease was partially offset by an increase in net sales of Accelerate PhenoTest BC Kits as customers completed their instrument verifications and began purchasing kits.

 $
 %

 During the year ended December 31, 2024, cost of sales decreased when compared to the year ended December 31, 2023. This decrease was due to reduced demand for Accelerate Pheno instruments during the year ended December 31, 2024 along with an excess inventory write-down of $1.2 million recorded during the year ended and December 31, 2023.

 During the year ended December 31, 2023, the Company took charges to cost of sales for inventory provisions primarily related to the write-down of excess quantities of instrument raw material and work in process inventory, whose inventory levels were higher than our updated forecasts of future demand for those products. Inventory provisions totaled $1.2 million during the year ended December 31, 2023, with no inventory provisions recorded for the year ended December 31, 2024.

 Total cost of sales less inventory write-downs and non-cash equity-based compensation expense during the year ended December 31, 2024, increased primarily due to higher kit sales volume and increases in costs to manufacture Accelerate PhenoTest BC Kits due to inflationary pressures, compared to the year ended December 31, 2023.

 Non-cash equity-based compensation expense is a component of manufacturing overhead and service cost of sales. Manufacturing overhead is capitalized as inventory and relieved to cost of sales when consumable tests are sold to a customer, instruments are sold to a customer, or when instruments are amortized to cost of sales.

 Cost of sales includes non-cash equity-based compensation expense of $0.1 million and $0.3 million for the years ended December 31, 2024 and 2023, respectively. During the year ended December 31, 2024, non-cash equity-based compensation expense decreased due to fewer equity awards granted and decreases in fair value of stock awards being granted.

 During the year ended December 31, 2024, gross profit increased primarily as a result of inventory provisions related to the write-down of excess quantities of raw material and work in process instrument inventory recorded during the year ended December 31, 2023. As described above, the Company recorded an inventory write-down of $1.2 million for the year ended December 31, 2023.

 Gross profit less inventory write-downs and non-cash equity-based compensation expense decreased during the year ended December 31, 2024, compared to the year ended December 31, 2023, primarily due to the decrease in gross margin as a result of higher costs to manufacture consumables.

 Inventory with zero cost basis was sold to customers for the years ended December 31, 2024 and 2023. Sales of pre-launch inventory previously not capitalized and expensed in a previous year for the years ended December 31, 2024 and 2023 was $0.4 million and $0.2 million, respectively.

 During the year ended December 31, 2024, our loss from operations decreased as compared to the year ended December 31, 2023, primarily due to lower Research and development and Sales, general and administrative expenses.

 Loss from operations includes non-cash equity-based compensation expense of $4.4 million and $5.4 million for the years ended December 31, 2024 and 2023, respectively. The decrease of non-cash equity-based compensation expense for each year was primarily the result of stock awards having a lower fair value primarily due to a decrease in the Company's stock price year over year.

 This loss and further losses are anticipated and are the result of our continued investments in key research and development program costs, and commercialization of the Company's products.

 During the year ended December 31, 2024, other expense, net, was primarily comprised of interest expense of $13.1 million and loss on fair value adjustments of $2.0 million.

 During the year ended December 31, 2023, other expense, net, is comprised of loss on extinguishment of debt of $6.5 million and loss on extinguishment of debt with related party of $6.8 million, both resulting from the consummation of the Restructuring Transactions (as defined below), interest expense of $5.9 million, and related party interest expense of $1.8 million. These expenses were partially offset by a $13.0 million gain on a fair-value adjustment mainly consisting of the derivative liability related to our 5.00% Notes as well as the Schuler Purchase Obligation (as defined below). The increase in interest expense for the year ended December 31, 2024, when compared to the prior year, was primarily the result of the Company's issuance of the 5.00% Notes in June 2023 and the issuance of the 16.00% Notes in August 2024.

 Capital Resources and Liquidity

 Since inception, the Company has not achieved profitable operations or positive cash flows from operations. The Company's accumulated deficit totaled $718.9 million as of December 31, 2024. During the year ended December 31, 2024, the Company had a net loss of $50.0 million and negative cash flows from operations of $24.2 million. The Company had negative working capital of $(9.0) million as of December 31, 2024.

 In March 2023, the Company entered into a forbearance agreement (the "Forbearance Agreement") with the holders of approximately 85% of the Company's outstanding 2.50% convertible senior notes (the 2.50% Notes") (collectively, the "Ad Hoc Noteholder Group") and the trustee for the 2.50% Notes (the "Trustee"). Pursuant to the Forbearance Agreement, the members of the Ad Hoc Noteholder Group agreed, and directed the Trustee, to forbear from exercising their rights and remedies under the indenture governing the 2.50% Notes (the "2.50% Notes Indenture") in connection with certain events of default under the 2.50% Notes Indenture, including, but not limited to, the failure to timely pay in full the principal and any interest related to the 2.50% Notes that was due and payable on March 15, 2023. In April 2023, the Company entered into a restructuring support agreement (the "Restructuring Support Agreement") with certain holders of the 2.50% Notes, the holder of a secured promissory note with the Jack W. Schuler Living Trust (the "Schuler Trust") (the "Secured Note") and the holders of the Company's Series A

 Preferred Stock to negotiate in good faith to effect the restructuring of the Company's capital structure (the "Restructuring Transactions").

 In June 2023, the Company completed the Restructuring Transactions contemplated by the Restructuring Support Agreement, which included, among other things, the issuance of $66.9 million aggregate principal amount of 5.00% Notes. Further details of the Forbearance Agreement, the Restructuring Transactions and the 5.00% Notes are included below and/or in Part II, Item 8, Note 11, Convertible Notes of this Form 10-K.

 In January 2024, the Company completed an underwritten public offering (the "January 2024 Public Units Offering") of Units and Pre-Funded Units (each, as defined below). Concurrently with the completion of the January 2024 Public Units Offering, the Company sold Units to the Schuler Trust and to the Company's Chief Executive Officer and Chief Financial Officer in a private placement offering. Aggregate net proceeds after transaction expenses were $11.0 million. In connection with the January 2024 Public Units Offering, the Schuler Trust agreed to and subsequently purchased additional Units in May 2024 for net proceeds of $2.7 million. Further information and a description of the Units and the Pre-Funded Units are included below and in Part II, Item 8, Note 18, Stockholders' Deficit.

 In August 2024, the Company entered into a note purchase agreement (the "Note Purchase Agreement") with certain investors named therein pursuant to which the Company issued $15.0 million aggregate principal amount of 16.00% Notes for net proceeds of approximately $14.2 million. Further information and a description of the 16.00% Notes are included below and in Part II, Item 8, Note 10, Notes Payable.

 As of December 31, 2024, the Company had $16.3 million in cash and cash equivalents and investments, an increase of $3.1 million from $13.2 million at December 31, 2023. The primary reason for the increase was due to proceeds from the sale and issuance of Units and Pre-Funded Units and proceeds from the issuance of 16.00% Notes during 2024, partially offset by cash used in operations. The future success of the Company is dependent on its ability to successfully commercialize its products, obtain regulatory clearance for and successfully launch its future product candidates, obtain additional capital and ultimately attain profitable operations.

 The Company's primary use of capital has been for the development and commercialization of the Accelerate Pheno system, development of complementary products and, most recently, development of its next generation technology, the Accelerate WAVE system. The Company is subject to a number of risks similar to other early commercial stage life science companies, including, but not limited to commercially launching the Company's products, development and market acceptance of the Company's product candidates, development by its competitors of new technological innovations, protection of proprietary technology and raising additional capital.

 Historically, the Company has funded its operations primarily through multiple equity raises and the issuance of debt. While the Company continues to fund and progress its development and operational goals discussed in this Form 10-K, it is not expected to be sufficient to fund the Company's operations through twelve months from the filing date of this Form 10-K.

 Management currently believes that it will be necessary for the Company to secure additional funds to continue its existing business to fund its obligations. While the Company continues to explore additional funding in the form of potential equity and/or debt financing arrangements or similar transactions, there can be no assurance the necessary financing will be available on terms acceptable to the Company, or at all. If the Company raises funds by issuing equity securities, dilution to stockholders may result. Any equity securities issued may also provide for rights, preferences or privileges senior to those of holders of common stock. If the Company raises funds by issuing additional debt, it is likely any new debt would have rights, preferences and privileges senior to common stockholders. The terms of borrowing could impose significant restrictions on the Company's operations. The capital markets have in the past, and may in the future, experience periods of upheaval that could impact the availability and cost of equity and debt financing. In addition, changes in federal fund rates set by the Federal Reserve, such as the significant increases experienced throughout 2022 and 2023, which serve as benchmark rates on borrowing, and other general economic conditions have impacted, and in the future may impact, the cost of debt financing or refinancing existing debt.

 In September 2024, the Company announced it has retained Perella Weinberg Partners to assist with the review of strategic alternatives. Although the Company is actively considering all available strategic alternatives to maximize value, if the Company is unable to obtain adequate capital resources to fund operations, the Company would not be able to continue to operate its business pursuant to its current plans. This may require the Company

 to, among other things, materially modify its operations to reduce spending; sell assets or operations; delay the implementation of, or revise certain aspects of, its business strategy; pursue strategic alternatives; or discontinue its operations entirely.

 The Company is required to evaluate its financial condition as of the filing date of this Form 10-K pursuant to the requirements of Accounting Standards Codification ("ASC") 205-40, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. Management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that the financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of management's plans that have not been fully implemented as of the date the financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company's ability to continue as a going concern. The mitigating effect of management's plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued.

 Based on its evaluation pursuant to ASC 205-40, the Company has determined that, as of the date of this Form 10-K filing, there is substantial doubt about its ability to continue as a going concern, as the Company does not currently have adequate financial resources to fund its forecasted operating costs for at least twelve months from the filing date of this Form 10-K.

 The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.

 Cash flows from operating activities

 The net cash used in operating activities was $24.2 million during the year ended December 31, 2024. Net cash used in operating activities was primarily the result of net losses. These amounts were partially offset by equity-based compensation, depreciation and amortization, amortization of debt discount and issuance costs, and PIK interest.

 The net cash used in operating activities was $40.2 million during the year ended December 31, 2023. Net cash used in operating activities was primarily the result of net losses and a gain on fair value adjustment, partially offset by losses on extinguishment of debt, equity-based compensation, an inventory write-down, depreciation and amortization, amortization of debt discount and issuance costs, and PIK interest.

 These losses are the result of continued investments in research and development to further mature the Accelerate Pheno system, develop complementary products, including the Accelerate Arc system, as well as develop our next generation technology, the Accelerate WAVE system, along with other factors.

 Cash flows from investing activities

 The net cash used by investing activities was $0.5 million for the year ended December 31, 2024, which were the result of purchases of equipment.

 The net cash provided by investing activities was $8.7 million for the year ended December 31, 2023. The Company had maturities of marketable securities of $9.7 million which were offset in part by purchases of equipment of $1.0 million.

 Cash flows from financing activities

 The net cash provided by financing activities was $27.1 million for the year ended December 31, 2024, which was primarily related to proceeds from the sale of Units and Pre-Funded Units of $15.0 million and proceeds from the issuance of 16.00% Notes of $15.0 million, partially offset by debt and equity issuance costs of $2.1 million.

 The net cash provided by financing activities was $9.0 million for the year ended December 31, 2023, which was primarily related to proceeds from the sale of common stock of $4.0 million and proceeds from issuance of 5.00% Notes of $10.0 million, partially offset by debt and equity issuance costs of $3.7 million and payments on finance leases of $1.3 million.

 Financing Activity

 Convertible Notes

 On June 9, 2023, the Company issued $66.9 million aggregate principal amount of 5.00% Notes in connection with the Restructuring Transactions described in Part II, Item 8, Note 11, Convertible Notes of this Form 10-K. The 5.00% Notes mature on December 15, 2026 and bear interest at a rate of 5.00% per annum, payable in kind. Interest is payable semi-annually in arrears June 15 and December 15 of each year, commencing on December 15, 2023. The 5.00% Notes, including any 5.00% Notes issued as a result of the payment of interest in kind, will be convertible into shares of the Company's common stock at an initial conversion price of approximately $7.20 per share, which reflects the initial conversion rate of 138.88889 shares of common stock per $1,000 principal amount of 5.00% Notes. The initial conversion price was subject to adjustment based on the positive difference between the 31 to 90 day volume-weighted average price, subject to a cap of $8.30 per share. On October 18, 2023, the Company evaluated the conversion rate in accordance with the terms of the 5.00% Notes and determined the initial conversion rate of 138.88889 shares of common stock per $1,000 principal amount will continue to be the conversion rate through the remaining term of the 5.00% Notes. Upon conversion of the 5.00% Notes, the Company will pay or deliver, as the case may be, cash, shares of the Company's common stock, or a combination of cash and shares of common stock, at the Company's election.

 The 5.00% Notes Indenture contains customary events of default, including, but not limited to, non-payment of principal or interest, breach of certain covenants in the 5.00% Notes Indenture, defaults under or failure to pay certain other indebtedness and certain events of bankruptcy, insolvency and reorganization. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the Collateral Agent (as defined below), by notice to the Company, or the holders of the 5.00% Notes representing at least 25% in aggregate principal amount of the outstanding 5.00% Notes, by notice to the Company and the Collateral Agent, may declare 100%of the principal of, and all accrued and unpaid interest on, all of the then outstanding 5.00% Notes to be due and payable immediately. Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal of, and all accrued and unpaid interest on, all of the then outstanding 5.00% Notes will automatically become immediately due and payable.

 Additionally, the Company and certain of its subsidiaries granted U.S. Bank Trust Company, National Association, a national banking association, as collateral agent (the "Collateral Agent"), a security interest in certain of their assets, including but not limited to certain accounts, equipment, fixtures and intellectual property, in order to secure the payment and performance of all of their Obligations (as defined in the 5.00% Notes Indenture) relating to the 5.00% Notes.

 In March and April 2018, the Company issued $171.5 million aggregate principal amount of 2.50% Notes. In September 2021 and March 2022, the Company entered into exchange agreements with certain holders of 2.50% Notes pursuant to which $65.0 million aggregate principal amount of 2.50% Notes were exchanged for an aggregate of approximately 1.7 million shares of the Company's common stock. On March 15, 2023, the remaining 2.50% Notes matured and became due and payable.

 In August 2022, the Company entered into an exchange agreement with the Schuler Trust pursuant to which the Schuler Trust agreed to exchange with the Company $49.9 million aggregate principal amount of 2.50% Notes held by it for (a) the Secured Note in an aggregate principal amount of $34.9 million and (b) a warrant (the "2022 Warrant") to acquire up to approximately 0.2 million shares of the Company's common stock at an exercise price of $21.20 per share (the "Exercise Price"). The 2022 Warrant may be exercised from February 15, 2023 through the earlier of (i) August 15, 2029 and (ii) the consummation of certain acquisition transactions involving the Company, as set forth in the 2022 Warrant. The number of shares underlying the 2022 Warrant and the Exercise Price are subject to certain customary proportional adjustments for fundamental events, including stock splits and recapitalizations, as set forth in the 2022 Warrant. The Secured Note, plus accrued interest, was repurchased by the Company in connection with the Restructuring Transactions through the issuance of approximately 3.4 million shares of common stock.

 In connection with the Restructuring Transactions, approximately $55.9 million aggregate principal amount of 2.50% Notes were exchanged for approximately $56.9 million aggregate principal amount of 5.00% Notes, which was inclusive of additional 5.00% Notes in respect of interest accrued on the 2.50% Notes from September 15, 2022. In April 2024, the Company settled the outstanding balance of its 2.50% Notes. The payment of approximately $0.8 million satisfied all outstanding principal and accrued interest remaining on the 2.50% Notes.

 In August and October 2023, certain holders of 5.00% Notes converted approximately $1.0 million of aggregate principal amount of 5.00% Notes held by them for approximately 0.1 million shares of the Company's common stock. In 2024, the Company issued $3.4 million of 5.00% PIK Notes to pay interest accrued on the 5.00% Notes outstanding.

 As of December 31, 2024, $71.0 million aggregate principal amount of 5.00% Notes were outstanding.

 See Part II, Item 8, Note 11, Convertible Notes of this Form 10-K for additional information.

 Sales of Equity Securities

 The Company has historically completed multiple equity raises through sales of its common and preferred stock in both public and private offerings, including the recent transactions below.

 In March 2022, the Company entered into a securities purchase agreement (the "March 2022 Securities Purchase Agreement") with the Schuler Trust for the issuance and sale by the Company of approximately 0.2 million shares of the Company's common stock to the Schuler Trust for an aggregate purchase price of $4.0 million. In June 2023 in connection with the Restructuring Transactions, the Company amended the March 2022 Securities Purchase Agreement and issued and sold approximately 0.5 million shares of the Company's common stock to the Schuler Trust for proceeds of $4.0 million.

 In June 2023, the Company entered into a purchase agreement with the Schuler Trust (the "Schuler Purchase Obligation") pursuant to which the Schuler Trust was required, at the Company's option, to either purchase approximately 1.4 million shares of common stock from the Company valued at $7.20 per share for an aggregate purchase price of $10.0 million or to backstop a public offering by the Company of common stock for aggregate proceeds of $10.0 million. If the Company elected to conduct a public offering of common stock and other investors purchased less than $10.0 million of common stock by December 15, 2023, the Schuler Trust would have the obligation to purchase $10.0 million of shares of common stock, less the amount of common stock purchased by other investors, and would have the right to purchase additional shares of common stock such that the total amount of common stock purchased by the Schuler Trust equaled $10.0 million of shares of common stock. If the Company elected to conduct a public offering of common stock and other investors purchased $10.0 million of shares of common stock by December 15, 2023, the Schuler Trust would have the right, but not the obligation, to purchase up to $10.0 million of shares of common stock at the public offering price for the backstopped offering up to a maximum aggregate purchase by the Schuler Trust of $10.0 million of common stock.

 In December 2023, the Company and the Schuler Trust entered into an amendment to the Schuler Purchase Obligation extending the deadline for the investment or public offering backstop through February 15, 2024 and the Schuler Trust agreed to purchase $2.0 million of shares at the public offering price if the aggregate gross proceeds to the Company resulting from the public offering was more than $10.0 million.

 In January 2024, the Company completed the January 2024 Public Units Offering consisting of 6.8 million units (the "Units"), each consisting of one share of common stock and one warrant to purchase one share of common stock (each, a "Common Warrant"), and for certain investors in lieu thereof, pre-funded Units (the "Pre-Funded Units"), each consisting of one pre-funded warrant to purchase one share of common stock (each, a "Pre-Funded Warrant"), and one Common Warrant to purchase one share of common stock. The public offering price for each Unit was $1.50 and the public offering price for each Pre-Funded Unit was $1.49.

 The Company granted the underwriters for the January 2024 Public Units Offering a 30-day option to purchase up to an additional 1.0 million shares of common stock and/or additional Common Warrants to purchase up to 1.0 million shares of common stock, in any combination thereof, at the public offering price, less underwriting discounts and commissions. The underwriters elected to purchase an additional 36,003 Common Warrants from the Company under this option.

 Common Warrants issued to investors in the January 2024 Public Units Offering have an exercise price of $1.65 per share, were immediately exercisable upon issuance and will remain exercisable until the date that is five years after their original issuance. The Pre-Funded Warrants have an exercise price of $0.01 per share, are immediately exercisable and will remain exercisable until exercised in full. The gross proceeds from the January 2024 Public Units Offering, before deducting underwriting discounts and commissions and other public offering expenses payable by the Company were approximately $10.2 million (excluding any proceeds that may be received upon the exercise of the Common Warrants or the Pre-Funded Warrants).

 Concurrently with the completion of the January 2024 Public Units Offering, the Company sold 1.2 million Units at a purchase price of $1.73 per Unit to the Schuler Trust, which satisfied the Schuler Purchase Obligation and an aggregate of 33,332 Units at a purchase price of $1.50 per Unit to the Company's Chief Executive Officer and Chief Financial Officer, in each case, in a private placement offering. The gross proceeds from the private placement offering, before deducting underwriting discounts and commissions and other expenses payable by the Company were approximately $2.0 million (excluding any proceeds that may be received upon the exercise of the Common Warrants).

 Pursuant to the subscription agreement entered into between the Schuler Trust and the Company in connection with the private placement offering of Units, the Schuler Trust also agreed to purchase an additional 1.6 million Units at a purchase price of $1.73 per Unit on or before May 20, 2024. On May 20, 2024, the Company completed the sale of such additional Units to the Schuler Trust for gross proceeds of approximately $2.7 million (before deducting underwriting discounts and commissions and other expenses payable by the Company and excluding any proceeds that may be received upon the exercise of the Common Warrants).

 Aggregate net proceeds from the January 2024 Public Units Offering and private placement offering of Units (including the additional Units purchased by the Schuler Trust in May 2024) were approximately $13.7 million.

 16.00% Notes

 In August 2024, the Company entered into the Note Purchase Agreement with certain investors named therein pursuant to which the Company issued $15.0 million aggregate principal amount of the 16.00% Notes.

 The 16.00% Notes will mature on December 31, 2025 and bear interest at a rate of 16.00% per annum, payable in kind. Interest on the 16.00% Notes is payable by the Company quarterly in arrears on the last business day of each March, June, September and December, beginning on September 30, 2024.

 Contemporaneously with the Note Purchase Agreement, the Company also entered into the 16.00% Notes Indenture with a trustee that provides that the 16.00% Notes will be secured by a super-priority security interest in the same collateral that secures the Company's outstanding 5.00% Notes.

 The 16.00% Notes Indenture contains customary events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the trustee, by notice to the Company, or the holders of the 16.00% Notes representing at least a majority in aggregate principal amount of the outstanding 16.00% Notes, by notice to the Company and the trustee, may declare 100% of the principal of, the premium (including the Exit Premium (as defined below)), and all accrued and unpaid interest on, all of the then outstanding 16.00% Notes to be due and payable immediately.

 Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal, the premium (including the Exit Premium), and all accrued and unpaid interest on, all of the then outstanding 16.00% Notes will automatically become immediately due and payable.

 Upon the occurrence of a change of control, the Company will be required to make an offer to repurchase all or any portion of the outstanding 16.00% Notes at a price in cash equal to 100% of the aggregate principal amount of the 16.00% Notes repurchased, plus the premium (including the Exit Premium), and all accrued and unpaid interest to, but excluding, the date or repurchase.

 Upon the occurrence of any repayment (including in connection with a change of control or an asset sale) or redemption or acceleration upon any event of default, the Company is required to pay the investors a fee equal to a certain percentage of the aggregate principal amount of the 16.00% Notes then outstanding plus accrued and unpaid interest thereon, which fee shall be equal to 30.00% if any such event occurs on or prior to June 30, 2025 and equal to 42.50% if any such event occurs on July 1, 2025 and thereafter (the "Exit Premium"). The Company also contemporaneously entered into other customary ancillary agreements in connection with the issuance of the 16.00% Notes.

 The 16.00% Notes Indenture also contains various affirmative, negative and financial covenants that, among other things, may restrict the ability of the Company and its subsidiaries to incur additional indebtedness, create certain liens, merge or consolidate with another entity, pay dividends or repurchase stock, and sell all or substantially all of their assets.

 Aggregate net proceeds from the issuance of the 16.00% Notes were approximately $14.2 million.

 Contractual Obligations

 The Company has certain contractual obligations and commercial commitments as disclosed in Part II, Item 8, Note 16, Commitments and Contingencies that do not meet the definition of long-term debt obligations, capital leases, operating leases or purchase obligations. The Company has entered into lease agreements as described in Part I, Item 2, Properties and Part II, Item 8, Note 9, Leases. The Company also has 5.00% Notes and 16.00% Notes outstanding as described above and in Part II, Item 8, Note 11, Convertible Notes and Part II, Item 8, Note 10, Notes Payable, respectively.

 Recent Accounting Pronouncements

 A discussion relating to recent accounting pronouncements can be found in Part II, Item 8, Note 2, Summary of Significant Accounting Policies.

 Critical Accounting Policies and Estimates

 Management's discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the U.S. ("U.S. GAAP"). The preparation of these financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the amounts reported in our consolidated financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates and judgments. We base our estimates on historical experience and on various other factors that are believed to be appropriate under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

 While our significant accounting policies are more fully described in Part II, Item 8, Note 2, Summary of Significant Accounting Policies, we believe that the following judgments are most critical to aid in fully understanding and evaluating our reported financial results.

 Inventory Valuation

 Inventory is stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first-out method. The Company estimates the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. The Company periodically analyzes its inventory levels to identify inventory that may expire prior to expected sale or has a cost basis in excess of its estimated realizable value and records a charge to expense for such inventory as appropriate.

 We charge cost of sales for inventory provisions to write-down our inventory to the lower of cost or net realizable value or for obsolete or excess inventory. Most of our inventory provisions relate to excess quantities of products, based on our inventory levels and future product purchase commitments compared to assumptions about future demand and market conditions. Once inventory has been written-off or written-down, it creates a new cost basis for the inventory that is not subsequently written-up.

 The Company manufactures pre-launch inventory in advance of regulatory approval. This inventory is expensed before an economic benefit is probable.

 See Part II, Item 8, Note 6, Inventory, for further information and related disclosures.

 Instruments Classified as Property and Equipment

 Property and equipment includes Accelerate Pheno and Accelerate Arc systems (also referred to as instruments) used for sales demonstrations, instruments under rental agreements and instruments used for research and development. Depreciation expense and losses from retirement of instruments used for sales demonstrations is recorded as a component of sales, general and administrative expense. Depreciation expense and losses from retirement of instruments placed at customer sites pursuant to reagent rental agreements is recorded as a component of cost of sales. Depreciation expense and losses from retirement of instruments used in our laboratory and research is recorded as a component of research and development expense. The Company retains title to these instruments and depreciates them over five years.

 The Company evaluates the recoverability of the carrying amount of its instruments whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, and at least annually. This evaluation is based on our estimate of future cash flows and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of instruments.

 For the years ended December 31, 2024 and 2023, the Company identified potential impairment indicators related to instruments installed at customer sites under rental agreement that are not generating revenue and the length of time from when these instruments are installed to when revenue will be generated. The Company's evaluation for impairment included consideration of the cash flows of current revenue generating instruments, the length of time to recover the carrying value, the historical rate of returned instruments from customers and the

 Company's ability to resell or repurpose used instruments. As a result of the Company's evaluation, no material impairment charges were recorded at December 31, 2024 and 2023.

 See Part II, Item 8, Note 7, Property and Equipment, for further information and related disclosures.

 Convertible Notes

 The Company follows Accounting Standard Update ("ASU") 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity's Own Equity (Subtopic 815-40) in accounting for its outstanding convertible notes. The convertible notes are accounted for as a liability measured at their amortized cost. Interest expense is comprised of (1) cash interest payments, (2) amortization of any debt discounts or premiums based on the original offering, and (3) amortization of any debt issuance costs. Gain or loss on extinguishment of notes is calculated as the difference between the (i) fair value of the consideration transferred and (ii) the sum of the carrying value of the debt at the time of repurchase, conversion or settlement.

 See Part II, Item 8, Note 11, Convertible Notes, for further information and related disclosures.

 Revenue Recognition

 The Company recognizes revenue when control of the promised good or service is transferred to its customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Sales taxes are excluded from revenues.

 The Company determines revenue recognition through the following steps:
 • Identification of the contract with a customer
 • Identification of the performance obligations in the contract
 • Determination of the transaction price
 • Allocation of the transaction price to the performance obligations
 • Recognition of revenue as we satisfy a performance obligation

 Product revenue is derived from the sale or rental of instruments and sales of related consumable products. When an instrument is sold, revenue is generally recognized upon installation of the unit consistent with contract terms, which do not include a right of return. When a consumable product is sold, revenue is generally recognized upon shipment. Invoices are generally issued when revenue is recognized. Payment terms vary by the type and location of the customer and the products or services offered. The term between invoicing and when payment is due is not significant.

 Service revenue is derived from the sale of extended service agreements which are generally non-cancellable. This revenue is recognized on a straight-line basis over the contract term beginning on the effective date of the contract because the Company is standing ready to provide services. Invoices are generally issued annually and coincide with the beginning of individual service terms.

 The Company's contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines relative standalone selling prices based on the price charged to customers for each individual performance obligation.

 Sales commissions earned by the Company's sales force are considered incremental and recoverable costs of obtaining a contract with a customer. The Company has determined these costs would have an amortization period of less than one year and has elected to recognize them as an expense when incurred. Contract asset opening and closing balances were immaterial for the years ended December 31, 2024 and 2023.

 Accelerate Diagnostics, Inc.

 Opinion on the Consolidated Financial Statements

 We have audited the accompanying consolidated balance sheet of Accelerate Diagnostics, Inc (the "Company") as of December 31, 2024, and the related consolidated statements of operations and comprehensive loss, stockholders' deficit, and cash flows for the year ended December 31, 2024, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024, and the results of its operations and its cash flows for the year ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

 Substantial Doubt Regarding Going Concern

 The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has suffered recurring losses and negative cash flows from operations that raise substantial doubt about the Company's ability to continue as a going concern. Management's plan in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

 Basis for Opinion

 These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

 Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audit provides a reasonable basis for our opinion.

 Critical Audit Matters

 The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

 January 2024 Units Offering

 As disclosed in Note 18 to the consolidated financial statements, in January 2024, the Company completed the January 2024 Units Offering, where in exchange for gross proceeds of approximately $10.2 million, the Company issued to each investor units consisting of one share of common stock and one warrant to purchase one share of

 common stock, and for certain investors, pre-funded units, each consisting of one pre-funded warrant to purchase one share of common stock, and one common warrant to purchase one share of common stock. Concurrently, and in connection with the completion of the January 2024 Units Offering, the Company entered into a forward contract with the Schuler Trust, to purchase additional units on or before May 20, 2024.

 We identified the evaluation of whether the instruments of the January 2024 Units Offering are to be liability or equity classified as a critical audit matter. The principal considerations for our determination included the subjectivity and judgment required to evaluate the provisions of the agreements when assessing the instruments' classification. Auditing the classification of these instruments involved especially challenging auditor judgment, including the extent of specialized skills and knowledge needed.

 The primary procedures we performed to address this critical audit matter included:

 • Evaluating the appropriateness of management's application of the accounting guidance in determining the classification of the instruments issued in conjunction with the January 2024 Units Offering in the consolidated financial statements by i) reviewing the relevant terms of the related agreements, ii) evaluating the completeness and accuracy of the Company's technical accounting analysis and the application of the relevant accounting literature.

 • Utilizing personnel with specialized knowledge and skills in technical accounting to assist in: i) evaluating the terms of the related agreements in relation to the relevant accounting literature, and ii) assessing the appropriateness of conclusions reached by the Company.

 Notes Payable – 16.00% Notes

 As disclosed in Note 10 to the consolidated financial statements, in August 2024, the Company entered into a Note Purchase Agreement with certain investors, whereby the Company issued notes payable in an aggregate principal amount of $15.0 million. The provisions of the Note Purchase Agreement were evaluated to determine whether there were any embedded features that required bifurcation from the host instrument which would be liability classified and recorded at fair value with subsequent changes in fair value recorded to earnings.

 We identified the evaluation of embedded features as a critical audit matter. The principal considerations for our determination included the subjectivity and judgment required to evaluate the provisions of the agreements when assessing potential bifurcation of certain embedded features to the agreements. Auditing the potential bifurcation of embedded features involved especially challenging auditor judgment, including the extent of specialized skills and knowledge needed.

 The primary procedures we performed to address this critical audit matter included:

 • Evaluating the appropriateness of management's application of the accounting guidance in assessing the accounting and classification of embedded features to the Note Purchase Agreement in the consolidated financial statements by i) reviewing the relevant terms of the Note Purchase Agreement, ii) evaluating the completeness and accuracy of the Company's technical accounting analysis and the application of the relevant accounting literature.

 • Utilizing personnel with specialized knowledge and skills in technical accounting to assist in: i) evaluating the terms of the Note Purchase Agreement in relation to the relevant accounting literature, and ii) assessing the appropriateness of conclusions reached by the Company.

 PCAOB ID Number 100

 Report of Independent Registered Public Accounting Firm

 To the Stockholders and the Board of Directors of Accelerate Diagnostics, Inc.

 Opinion on the Financial Statements

 We have audited the accompanying consolidated balance sheet of Accelerate Diagnostics, Inc. (the Company) as of December 31, 2023, the related consolidated statements of operations and comprehensive loss, stockholders' deficit and cash flows for the year ended December 31, 2023, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023, and the results of its operations and its cash flows for the year ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

 The Company's Ability to Continue as a Going Concern

 The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has suffered recurring losses and negative cash flows from operations, and has stated that substantial doubt exists about the Company's ability to continue as a going concern. Management's evaluation of the events and conditions and management's plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

 Basis for Opinion

 These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

 We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

 Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

 We have served as the Company's auditor from 2013 to 2024.

 NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

 NOTE 1. ORGANIZATION AND NATURE OF BUSINESS; BASIS OF PRESENTATION; PRINCIPLES OF CONSOLIDATION

 Accelerate Diagnostics, Inc. ("we" or "us" or "our" or "Accelerate" or the "Company") is an in vitro diagnostics company dedicated to providing solutions that improve patient outcomes and lower healthcare costs through the rapid diagnosis of serious infections.

 Basis of Presentation

 The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"), and applicable rules and regulations of the U.S. Securities and Exchange Commission ("SEC"), regarding annual financial reporting.

 All amounts are rounded to the nearest thousand dollars unless otherwise indicated.

 On July 11, 2023, the Company effected a one-for-ten reverse stock split ("Reverse Stock Split"). Consequently, on the Company's consolidated balance sheets, the aggregate par value of the issued common stock was reduced by reclassifying the par value amount of the eliminated shares of common stock to additional paid-in capital. All per share amounts and outstanding shares, including all common stock equivalents, have been retroactively restated in the consolidated financial statements and in the notes to the consolidated financial statements for all periods presented to reflect the Reverse Stock Split.

 Principles of Consolidation

 The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries after elimination of intercompany transactions and balances.

 Liquidity and Going Concern

 Since inception, the Company has not achieved profitable operations or positive cash flows from operations. The Company's accumulated deficit totaled $ 718.9 million as of December 31, 2024. During the year ended December 31, 2024, the Company had a net loss of $ 50.0 million and negative cash flows from operations of $ 24.2 million. The Company had negative working capital of $( 9.0) million as of December 31, 2024.

 In March 2023, the Company entered into a forbearance agreement (the "Forbearance Agreement") with the holders of approximately 85 % of the Company's outstanding 2.50 % convertible senior notes (the " 2.50 % Notes") (collectively, the "Ad Hoc Noteholder Group") and the trustee for the 2.50 % Notes (the "Trustee"). Pursuant to the Forbearance Agreement, the members of the Ad Hoc Noteholder Group agreed, and directed the Trustee, to forbear from exercising their rights and remedies under the indenture governing the 2.50 % Notes (the " 2.50 % Notes Indenture") in connection with certain events of default under the 2.50 % Notes Indenture, including, but not limited to, the failure to timely pay in full the principal and any interest related to the 2.50 % Notes that was due and payable on March 15, 2023. In April 2023, the Company entered into a restructuring support agreement (the "Restructuring Support Agreement") with certain holders of the 2.50 % Notes, the holder of a secured promissory note with the Jack W. Schuler Living Trust (the "Schuler Trust") (the "Secured Note") and the holders of the Company's Series A Preferred Stock to negotiate in good faith to effect the restructuring of the Company's capital structure (the "Restructuring Transactions").

 In June 2023, the Company completed the Restructuring Transactions contemplated by the Restructuring Support Agreement, which included, among other things, the issuance of $ 66.9 million aggregate principal amount of 5.00 % Senior Secured Convertible Notes due 2026 (the " 5.00 % Notes"). Further details of the Forbearance Agreement, the Restructuring Transactions and the 5.00 % Notes are included in Note 11, Convertible Notes.

 In January 2024, the Company completed an underwritten public offering (the "January 2024 Public Units Offering") of Units and Pre-Funded Units (each, as defined in Note 18, Stockholders' Deficit). Concurrently with the completion of the January 2024 Public Units Offering, the Company sold Units to the Schuler Trust and to the Company's Chief Executive Officer and Chief Financial Officer in a private placement offering. Aggregate net

 proceeds after transaction expenses were $ 11.0 million. In connection with the January 2024 Public Units Offering, the Schuler Trust agreed to and subsequently purchased additional Units in May 2024 for net proceeds of $ 2.7 million. Further information and a description of the Units and the Pre-Funded Units are included in Note 18, Stockholders' Deficit.

 In August 2024, the Company entered into a note purchase agreement (the "Note Purchase Agreement") with certain investors named therein pursuant to which the Company issued $ 15.0 million aggregate principal amount of the Company's 16.00 % Super-Priority Senior Secured PIK Notes due 2025 (the " 16.00 % Notes") for net proceeds of approximately $ 14.2 million. Further information and a description of the 16.00 % Notes are included in Note 10, Notes Payable.

 As of December 31, 2024, the Company had $ 16.3 million in cash and cash equivalents and investments, an increase of $ 3.1 million from $ 13.2 million at December 31, 2023. The primary reason for the increase was due to proceeds from the sale and issuance of Units and Pre-Funded Units and proceeds from the issuance of 16.00 % Notes during 2024, partially offset by cash used in operations. The future success of the Company is dependent on its ability to successfully commercialize its products, obtain regulatory clearance for and successfully launch its future product candidates, obtain additional capital and ultimately attain profitable operations.

 The Company's primary use of capital has been for the development and commercialization of the Accelerate Pheno system, development of complementary products and, most recently, development of its next generation technology, the Accelerate WAVE system. The Company is subject to a number of risks similar to other early commercial stage life science companies, including, but not limited to commercially launching the Company's products, development and market acceptance of the Company's product candidates, development by its competitors of new technological innovations, protection of proprietary technology and raising additional capital.

 Historically, the Company has funded its operations primarily through multiple equity raises and the issuance of debt. While the Company believes it has funding to allow it to progress its development and operational goals discussed in this report, it is not expected to be sufficient to fund the Company's operations through twelve months from the date of issuance of these consolidated financial statements.

 Management currently believes that it will be necessary for the Company to secure additional funds to continue its existing business and to fund its obligations.

 While the Company continues to explore additional funding in the form of potential equity and/or debt financing arrangements or similar transactions, there can be no assurance the necessary financing will be available on terms acceptable to the Company, or at all. If the Company raises funds by issuing equity securities, dilution to stockholders may result. Any equity securities issued may also provide for rights, preferences or privileges senior to those of holders of common stock. If the Company raises funds by issuing additional debt, it is likely any new debt would have rights, preferences and privileges senior to common stockholders. The terms of borrowing could impose significant restrictions on the Company's operations. The capital markets have in the past, and may in the future, experience periods of upheaval that could impact the availability and cost of equity and debt financing. In addition, changes in federal fund rates set by the Federal Reserve, such as the significant increases experienced throughout 2022 and 2023, which serve as benchmark rates on borrowing, and other general economic conditions have impacted, and in the future may impact, the cost of debt financing or refinancing existing debt.

 In September 2024, the Company announced that it has retained Perella Weinberg Partners to assist with the review of strategic alternatives. Although the Company is actively considering all available strategic alternatives to maximize value, if the Company is unable to obtain adequate capital resources to fund operations, the Company would not be able to continue to operate its business pursuant to its current plans. This may require the Company to, among other things, materially modify its operations to reduce spending; sell assets or operations; delay the implementation of, or revise certain aspects of, its business strategy; strategic alternatives; or discontinue its operations entirely.

 The Company is required to evaluate its financial condition as of the filing date of this report pursuant to the requirements of Accounting Standards Codification ("ASC") 205-40, Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. Management must evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the Company's ability to continue as a going concern within one year after the date that the financial statements are issued. This evaluation initially does not take into consideration the potential mitigating effect of management's plans that have not been fully implemented as of

 the date the financial statements are issued. When substantial doubt exists under this methodology, management evaluates whether the mitigating effect of its plans sufficiently alleviates substantial doubt about the Company's ability to continue as a going concern. The mitigating effect of management's plans, however, is only considered if both (1) it is probable that the plans will be effectively implemented within one year after the date that the financial statements are issued, and (2) it is probable that the plans, when implemented, will mitigate the relevant conditions or events that raise substantial doubt about the entity's ability to continue as a going concern within one year after the date that the financial statements are issued.

 Based on its evaluation pursuant to ASC 205-40, the Company has determined that, as of the filing date of this report, there is substantial doubt about its ability to continue as a going concern, as the Company does not currently have adequate financial resources to fund its forecasted operating costs for at least twelve months from the date of issuance of these consolidated financial statements.

 The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.

 NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Use of Estimates

 The preparation of the Company's consolidated financial statements requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and the related disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. The more significant areas requiring the use of management estimates and assumptions relate to accounts receivable, inventory, property and equipment, accrued liabilities, warranty liabilities, convertible notes, bifurcated derivatives, fair value instruments, tax valuation accounts and uncertain tax positions, equity–based compensation, revenue and leases. Actual results could differ materially from those estimates.

 Estimated Fair Value of Financial Instruments
 The Company follows ASC 820, Fair Value Measurement, which has defined fair value and requires the Company to establish a framework for measuring and disclosing fair value. The framework requires the valuation of assets and liabilities subject to fair value measurements using a three-tiered approach and fair value measurement be classified and disclosed in one of the following three categories:
 • Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;
 • Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and
 • Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
 The carrying amounts of financial instruments such as cash and cash equivalents, trade accounts receivable, prepaid expenses, other current assets, accounts payable, accrued liabilities and other current liabilities approximate the related fair values due to the short-term maturities of these instruments.
 See Note 4, Fair Value of Financial Instruments, for further information and related disclosures regarding the Company's fair value measurements.
 Cash and Cash Equivalents

 All highly liquid investments with an original maturity of three months or less at time of purchase are

 considered to be cash equivalents. Cash and cash equivalents include overnight repurchase agreement accounts and other investments. As part of the Company's cash management process, excess operating cash is invested in overnight repurchase agreements with its bank. Repurchase agreements and other investments classified as cash and cash equivalents are not deposits and are not insured by the U.S. government, the Federal Deposit Insurance Corporation (the "FDIC") or any other government agency and involve investment risk including possible loss of principal. The Company diversifies its cash holdings, but does have deposits at three institutions in excess of the FDIC coverage limit. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company's financial condition, results of operations, and cash flows.

 Investments

 The Company invests in various debt and equity securities which are primarily held in the custody of major financial institutions. Debt securities consist of certificates of deposit, U.S. government and agency securities, commercial paper, and corporate notes and bonds. Equity securities consist of mutual funds. The Company records these investments in the consolidated balance sheets at fair value. Unrealized gains or losses for debt securities available-for-sale are included in accumulated other comprehensive loss, a component of stockholders' deficit. Unrealized gains or losses for equity securities are included in other income (expense), net, a component of the consolidated statements of operations and comprehensive loss. The Company considers all debt securities to be available-for-sale, including those with maturity dates beyond 12 months, as they are available to support current operational liquidity needs. The Company classifies its investments as current based on the nature of the investments and their availability for use in current operations.

 We perform an assessment to determine whether there have been any events or economic circumstances to indicate that a debt security available-for-sale in an unrealized loss position has suffered impairment as a result of credit loss or other factors. A debt security is considered impaired if its fair value is less than its amortized cost basis at the reporting date.

 If we intend to sell the debt security or if it is more likely than not that we will be required to sell the debt security before the recovery of its amortized cost basis, the impairment is recognized and the unrealized loss is recorded as a direct write-down of the security's amortized cost basis with an offsetting entry to earnings. If we do not intend to sell the debt security or believe we will not be required to sell the debt security before the recovery of its amortized cost basis, the impairment is assessed to determine if a credit loss component exists. We use a discounted cash flow method to determine the credit loss component. In the event a credit loss exists, an allowance for credit losses is recorded in earnings for the credit loss component of the impairment while the remaining portion of the impairment attributable to factors other than credit loss is recognized, net of tax, in accumulated other comprehensive loss. The amount of impairment recognized due to credit factors is limited to the excess of the amortized cost basis over the fair value of the security.

 Accounts Receivable

 Accounts receivable consist of amounts due to the Company for sales to customers and are based on what we expect to collect in exchange for goods and services. Receivables are considered past due based on the contractual payment terms and are written off if reasonable collection efforts prove unsuccessful. Trade accounts receivable, net opening balance for the years ended December 31, 2024 and 2023 was $ 2.6 million and $ 2.4 million, respectively.

 We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as general and administrative expense in the consolidated statements of operations and comprehensive loss. We assess collectibility by reviewing accounts receivable on a collective basis where similar characteristics exist and on an individual basis when we identify specific customers with known disputes or collectibility issues. In determining the amount of the allowance for credit losses, we consider historical collectibility and make judgments about the creditworthiness of customers based on credit evaluations. Our customers typically have good credit quality. We also consider customer-specific information, current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data.

 The allowance for credit losses over trade receivables and net investment in sales-type leases for the years ended December 31 is comprised of the following (in thousands):

 The provisions recorded during the years ended December 31, 2024 and 2023, are primarily in connection with at-risk trade receivables and aged net investment in sales-type leases. See Note 9, Leases, for further information.

 Inventory
 Inventory is stated at the lower of cost or net realizable value. The Company determines the cost of inventory using the first-in, first-out method. The Company estimates the recoverability of inventory by reference to internal estimates of future demands and product life cycles, including expiration. The Company periodically analyzes its inventory levels to identify inventory that may expire prior to expected sale, has a cost basis in excess of its estimated realizable value, or is considered in excess of demand. These types of inventory events could result in a change to expense as appropriate.

 We charge cost of sales for inventory provisions to write down our inventory to the lower of cost or net realizable value or for obsolete or excess inventory. Most of our inventory provisions relate to excess quantities of products, based on our inventory levels and future product purchase commitments compared to assumptions about future demand and market conditions. Once inventory has been written off or written down, it creates a new cost basis for the inventory that is not subsequently written up.

 The Company manufactures pre-launch inventory in advance of regulatory approval. This inventory is expensed before an economic benefit is probable.

 See Note 6, Inventory, for further information and related disclosures.

 Property and Equipment
 Property and equipment are recorded at cost. Maintenance and repairs are charged to expense as incurred and expenditures for major improvements are capitalized. Depreciation of property and equipment is computed using the straight-line method over the estimated useful life of the assets, ranging from one to seven years. Leasehold improvements are depreciated over the remaining life of the lease or the life of the asset, whichever is less.

 Instruments Classified as Property and Equipment
 Property and equipment include Accelerate Pheno and Accelerate Arc systems (also referred to as instruments) used for sales demonstrations, instruments under rental agreements and instruments used for research and development. Depreciation expense and losses from retirement of instruments used for sales demonstrations are recorded as a component of sales, general and administrative expenses. Depreciation expense and losses from retirement of instruments placed at customer sites pursuant to reagent rental agreements are recorded as a component of cost of sales. Depreciation expense and losses from retirement of instruments used in our laboratory and research are recorded as a component of research and development expense. The Company retains title to these instruments and depreciates them over five years.

 The Company evaluates the recoverability of the carrying amount of its instruments whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable, and at least annually. This evaluation is based on our estimate of future cash flows and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of instruments.

 For the years ended December 31, 2024 and 2023, the Company identified potential impairment indicators related to instruments installed at customer sites under rental agreement that have not yet generated revenue and the length of time from when these instruments are installed to when revenue is initially generated. The Company's evaluation for impairment included consideration of the cash flows of current revenue generating instruments, the length of time to recover the carrying value, the historical rate of returned instruments from customers and the Company's ability to resell or repurpose used instruments. As a result of the Company's evaluation, no material impairment charges were recorded at December 31, 2024 and 2023.

 See Note 7, Property and Equipment, for further information and related disclosures.

 Long-lived Assets

 Long-lived assets and certain identifiable intangibles to be held and used by the Company are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The Company continuously evaluates the recoverability of its long-lived assets based on estimated future cash flows from and the estimated fair value of such long-lived assets, and provides for impairment if such undiscounted cash flows or the estimated fair value are insufficient to recover the carrying amount of the long-lived asset.

 Warranty Reserve

 Instruments are typically sold with a one year limited warranty, while kits and accessories are typically sold with a sixty-day limited warranty. Accordingly, a provision for the estimated cost of the limited warranty repair is recorded at the time revenue is recognized. Our estimated warranty provision is based on our estimate of future repair events and the related estimated cost of repairs. The Company periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary. The cost incurred for these provisions is included in cost of sales on the consolidated statements of operations and comprehensive loss.

 Convertible Notes

 The Company follows Accounting Standards Update ("ASU") 2020-06, Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity's Own Equity (Subtopic 815-40), in accounting for its outstanding convertible notes. The convertible notes are accounted for as a liability measured at their amortized cost. Interest expense is comprised of (1) cash interest payments, (2) amortization of any debt discounts or premiums based on the original offering, and (3) amortization of any debt issuance costs. Gain or loss on extinguishment of notes is calculated as the difference between the (i) fair value of the consideration transferred and (ii) the sum of the carrying value of the debt at the time of repurchase, conversion or settlement.

 Accounting for Derivatives

 Upon issuance of the 5.00 % Notes, each holder has the right, at their option, to convert any portion to common stock ("Conversion Option"). The conversion price initially was not fixed and therefore, the Conversion Option represented a derivative financial instrument and was recorded at its estimated fair value as a derivative liability in the consolidated balance sheets through October 17, 2023, the date at which the conversion price was fixed. Changes in the fair value of the derivative financial instrument were recognized in gain on fair value adjustment within the consolidated statements of operations and comprehensive loss. The derivative liability was derecognized and reclassified to equity as of October 17, 2023 once the conversion price was fixed and after completion of the final mark-to-market fair value adjustment as of that date. See Note 11, Convertible Notes, for

 further information regarding the Conversion Option.
 Warrants
 The Company accounts for its warrants as either equity-classified or liability-classified instruments based on an assessment of the specific terms of the warrants considering the authoritative guidance in ASC 480, Distinguishing Liabilities from Equity, and ASC 815, Derivatives and Hedging. The assessment considers whether the warrants meet the definition of a liability pursuant to ASC 480 and meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company's own common stock and satisfy additional conditions for equity classification. Warrants that are liability-classified, meet the definition of a derivative instrument, and do not qualify for any scope exceptions for derivative instrument accounting are measured at fair value at each reporting date in accordance with the guidance in ASC 820, Fair Value Measurement, with any subsequent changes in fair value recognized in the unaudited consolidated statements of operations and comprehensive loss. Warrants that are equity-classified are recorded as contributed capital on the consolidated statements of stockholders' deficit without further remeasurement.
 Revenue Recognition

 The Company recognizes revenue when control of the promised good or service is transferred to its customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Sales taxes are excluded from revenues.

 The Company determines revenue recognition through the following steps:
 • Identification of the contract with a customer
 • Identification of the performance obligations in the contract
 • Determination of the transaction price
 • Allocation of the transaction price to the performance obligations
 • Recognition of revenue as we satisfy a performance obligation

 Product revenue is derived from the sale or rental of instruments and sales of related consumable products. When an instrument is sold, revenue is generally recognized upon installation or transfer of control in sales to third party distributors consistent with contract terms, which do not include a right of return. When a consumable product is sold, revenue is generally recognized upon shipment. Invoices are generally issued when revenue is recognized. Payment terms vary by the type and location of the customer and the products or services offered. The term between invoicing and when payment is due is not significant.

 Service revenue is derived from the sale of extended service agreements which are generally non-cancellable. This revenue is recognized on a straight-line basis over the contract term beginning on the effective date of the contract because the Company is standing ready to provide services. Invoices are generally issued annually and coincide with the beginning of individual service terms.

 The Company's contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines relative standalone selling prices based on the price charged to customers for each individual performance obligation.

 Sales commissions earned by the Company's sales force and external sales agents are considered incremental and recoverable costs of obtaining a contract with a customer. The Company has determined these costs would have an amortization period of less than one year and has elected to recognize them as an expense when incurred. Contract asset opening and closing balances were immaterial for the years ended December 31, 2024 and 2023.

 Shipping and Handling

 Shipping and handling costs billed to customers are included as a component of revenue. The corresponding expense incurred with third party carriers is included as a component of sales, general and administrative costs on the consolidated statements of operations and comprehensive loss.

 Leases

 The Company accounts for leases in accordance with ASC 842, Leases. The Company determines if an arrangement is or contains a lease and the type of lease at inception. The Company classifies leases as finance leases (lessee) or sales-type leases (lessor) when there is either a transfer of ownership of the underlying asset by the end of the lease term, the lease contains an option to purchase the asset that we are reasonably certain will be exercised, the lease term is for the major part of the remaining economic life of the asset, the present value of the lease payments and any residual value guarantee equals or substantially exceeds all the fair value of the asset, or the asset is of such a specialized nature that it will have no alternative use to the lessor at the end of the lease term. Payments contingent on future events (i.e., based on usage) are considered variable and excluded from lease payments for the purposes of classification and initial measurement. Several of our leases include options to renew or extend the term upon mutual agreement of the parties and others include one-year extensions exercisable by the lessee. None of our leases contain residual value guarantees, restrictions, or covenants.

 To determine whether a contract contains a lease, the Company uses its judgment in assessing whether the lessor retains a material amount of economic benefit from an underlying asset, whether explicitly or implicitly identified, which party holds control over the direction and use of the asset, and whether any substantive substitution rights over the asset exist.

 Leases as Lessee

 Operating and finance leases are included in right-of-use ("ROU") assets and corresponding lease liabilities, within our consolidated balance sheets. These assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and their related liabilities are recognized at commencement date based on the present value of lease payments over the lease term. Typically, we use our incremental borrowing rate based on the information available at commencement in determining the present value of lease payments. We use the implicit rate when readily determinable. ROU assets are net of lease payments made and exclude lease incentives. Lease expense for lease payments is recognized on a straight-line basis over the lease term, which may include options to extend or terminate the lease when it is reasonably certain that we will exercise the option.

 Short-term leases have a lease term of twelve months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. Lease payments for short-term leases are recognized within the consolidated statements of operations and comprehensive loss in the period in which the obligation is incurred.

 Our operating leases consist primarily of leased office, factory, and laboratory space in the U.S., have between one - and six-year terms, and typically contain penalizing, early-termination provisions. Our finance leases consist of leased equipment and have three-year terms. Short-term leases consist of rental cars and copier leases.

 Leases as Lessor

 The Company leases instruments to customers under "reagent rental" agreements, whereby the customer agrees to purchase consumable products over a stated term, typically five years or less, for a volume-based price that includes an embedded rental for the instruments. When collectibility is probable, that amount is recognized as income at lease commencement for sales-type leases and as product is shipped, typically in a straight–line pattern, over the term for operating leases, which typically include a termination without cause or penalty provision given a short notice period. In some of these contracts, the customer has an option to purchase the underlying asset at a specified price.

 Consideration is allocated between lease and non-lease components based on standalone selling price in accordance with ASC 606, Revenue from Contracts with Customers.

 Net investment in sales-type leases is included within our consolidated balance sheets as a component of other current assets and other non-current assets, which include the present value of lease payments not yet received and the present value of the residual asset. These amounts are determined using the information available at commencement, including the lease term, estimated useful life, rate implicit in the lease, purchase options (if any and if such option is reasonably certain to be exercised), and expected fair value of the instrument.

 See Note 9, Leases, for further information.
 Nonqualified Cash Deferral Plan
 The Company's Cash Deferral Plan (the "Deferral Plan") provides certain key employees, with an opportunity to defer the receipt of such participant's base salary. The Deferral Plan is intended to be a nonqualified deferred compensation plan that complies with the provisions of Section 409A of the Internal Revenue Code. All of the investments held in the Deferral Plan are equity securities consisting of mutual funds and recorded at fair value with changes in the investments' fair value recognized as earnings in the period they occur. The corresponding liability for the Deferral Plan is included in other non-current liabilities in the consolidated balance sheets.
 Equity-Based Compensation

 The Company may award stock options, restricted stock units ("RSUs"), performance-based awards and other equity-based instruments to its employees, directors and consultants. Annual bonus equity-based awards are typically granted based upon meeting goals and objectives for a given year as determined in the following year after the Company's financials are prepared, final results are reasonably certain, and the compensation committee has authorized the awards. Given the compensation committee has unilateral authority to modify the amount of the awards, the criteria for payout, vesting terms, etc., the Company has elected a narrow approach to determining the grant date and, as such, the grant date is based on compensation committee approval. Compensation cost related to equity-based instruments is based on the fair value of the instrument on the grant date, and is recognized over the requisite service period on a straight-line basis over the vesting period for each tranche (an accelerated attribution method). Performance-based awards vest based on the achievement of performance targets. Compensation costs associated with performance-based awards are recognized over the requisite service period based on probability of achievement. Performance-based awards require management to make assumptions regarding the likelihood of achieving performance targets.

 The Company estimates the fair value of service-based and performance-based stock option awards, including modifications of stock option awards, using the Black-Scholes option pricing model. This model derives the fair value of stock options based on certain assumptions related to expected stock price volatility, expected option life, risk-free interest rate and dividend yield.

 • Volatility: The expected volatility is based on the historical volatility of the Company's stock price over the most recent period commensurate with the expected term of the stock option award.
 • Expected term: The estimated expected term for employee awards is based on a simplified method that considers an insufficient history of employee exercises. For consultant awards, the estimated expected term is the same as the life of the award.
 • Risk-free interest rate: The risk-free interest rate is based on published U.S. Treasury rates for a term commensurate with the expected term.
 • Dividend yield: The dividend yield is estimated as zero as the Company has not paid dividends in the past and does not have any plans to pay any dividends in the foreseeable future.

 The Company accounts for forfeitures as they occur rather than on an estimated basis.
 The Company records the fair value of RSUs or stock grants based on the published closing market price on the day before the grant date.

 See Note 14, Equity-Based Compensation, for further information.

 Deferred Tax Assets and Liabilities

 Deferred tax assets and liabilities are recorded for the estimated future tax effects of temporary differences between the tax basis of assets and liabilities and amounts reported in the accompanying consolidated balance sheets. The change in deferred tax assets and liabilities for the period represents the deferred tax provision or benefit for the period. Effects of changes in enacted tax laws in deferred tax assets and liabilities are reflected as an adjustment to the tax provision or benefit in the period of enactment.

 The Company follows the provisions of ASC 740, Income Taxes, to account for any uncertainty in income

 taxes with respect to the accounting for all tax positions taken (or expected to be taken) on any income tax return. This guidance applies to all open tax periods in all tax jurisdictions in which the Company is required to file an income tax return. Under U.S. GAAP, in order to recognize an uncertain tax benefit the taxpayer must be more likely than not certain of sustaining the position, and the measurement of the benefit is calculated as the largest amount that is more likely than not to be realized upon resolution of the position. Interest and penalties, if any, would be recorded within tax expense.

 Foreign Currency Translation and Foreign Currency Transactions

 Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars are included in the foreign currency translation adjustment, a component of accumulated other comprehensive loss in the consolidated statements of stockholders' deficit.

 The Company has assets and liabilities, including receivables and payables, which are denominated in currencies other than their functional currency. These balance sheet items are subject to re-measurement, the impact of which is recorded in foreign currency exchange gain and loss, within the consolidated statements of operations and comprehensive loss.

 Loss Per Share

 Basic loss per share includes no dilution and is computed by dividing loss available to common stockholders by the weighted average number of common shares outstanding for the period (including shares underlying Pre-Funded Warrants). Potentially dilutive common shares consist of shares issuable from stock options, unvested RSUs and warrants (other than Pre-Funded Warrants, which are already included in the weighted average number of common shares outstanding), as well as shares that would be outstanding if the 5.00 % Notes were converted and shares that would be outstanding if the Schuler Purchase Obligation (as defined in Note 11, Convertible Notes) was exercised. Diluted earnings are not presented when the effect of adding such additional common shares is antidilutive.

 See Note 13, Loss Per Share, for further information.

 Comprehensive Loss

 In addition to net loss, comprehensive loss includes all changes in equity during a period, except those resulting from investments by and distributions to owners. The Company holds debt securities as available-for-sale and records the change in fair market value as a component of comprehensive loss. The Company also has adjustments resulting from translating foreign functional currency financial statements into U.S. dollars which is included as a component of comprehensive loss.

 Recent Accounting Pronouncements

 Standards that were recently adopted

 In November 2023, the Financial Accounting Standards Board ("FASB") issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands disclosure requirements to require entities to disclose significant segment expenses that are regularly provided to or easily computed from information regularly provided to the chief operating decision maker. This update also requires all annual disclosures currently required by Topic 280 to be disclosed in interim periods. The new disclosure requirements are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and are to be applied retrospectively to all periods presented. The Company has evaluated the expanded disclosure requirements and provided such improved disclosure information within Note 17, Segment, Geographic and Revenue Disaggregation

 Standards not yet adopted

 In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands the existing rules on income tax disclosures. This update requires entities to disclose specific categories in the tax rate reconciliation, provide additional information for reconciling items that meet a quantitative threshold and disclose additional information about income taxes paid on an annual basis. The new disclosure requirements are effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. We are currently evaluating these new expanded disclosure requirements.

 NOTE 3. CONCENTRATION OF CREDIT RISK

 Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments and accounts receivable, including receivables from major customers.

 The Company has financial institutions for banking operations that hold 10% or more of the Company's cash and cash equivalents. As of December 31, 2024, one of the Company's financial institutions held 78 % of the Company's cash and cash equivalents. As of December 31, 2023, two of the Company's financial institutions held 61 % and 25 % of the Company's cash and cash equivalents, respectively.

 The Company grants credit to domestic and international customers in various industries. Exposure to losses on accounts receivable is principally dependent on each customer's financial position. The Company had one customer that accounted for 13 % of the Company's trade accounts receivable balance as of December 31, 2024 and 2023.

 The Company had one customer that represented 12 % of the Company's net sales for the year ended December 31, 2024 and no customers that represented 10% or more of the Company's net sales for the year ended December 31, 2023.

 Highly liquid investments with an original maturity of three months or less at time of purchase are included in cash and cash equivalents on the consolidated balance sheets.

 Level 1: Assets are priced using quoted prices in active markets for identical assets which include money market funds, U.S. Treasury securities and mutual funds as these specific assets are liquid;

 Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

 Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).

 There were no transfers between levels during the years ended December 31, 2024 and 2023.

 For certain other financial assets and liabilities, including accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.

 Liabilities for Which Fair Value is Only Disclosed

 At December 31, 2024, the Company's 5.00 % Notes, issued in June 2023, had an outstanding principal balance of $ 71.0 million and a fair value of $ 54.8 million, using Level 3 measurement assumptions.

 At December 31, 2023, the Company's 5.00 % Notes had an outstanding principal balance of $ 67.6 million and a fair value of $ 50.8 million, using Level 3 measurement assumptions.

 The 2.50 % Notes matured on March 15, 2023 and became due and payable on such date. The amortized carrying amount of the 2.50 % Notes is $ 0.7 million as of December 31, 2023 and approximates the related fair value due to the instrument being fully matured and payable.

 See Note 11, Convertible Notes, for further detail on the 2.50 % and 5.00 % Notes.

 The fair value of short-term debt obligations, or the 16.00% Notes, approximates the carrying value due to the short maturities of the debt instruments.

 See Note 10, Notes Payable, for further detail on the 16.00% Notes.

 NOTE 5. INVESTMENTS

 The Company did not have any debt securities classified as available-for-sale investments at December 31, 2024 or 2023.

 There were no material proceeds (including principal paydowns) or realized gains or losses from sales of debt securities available-for-sale for the years ended December 31, 2024 and 2023. The Company determines gains and losses on marketable securities based on specific identification of the securities sold. No material balances were reclassified out of accumulated other comprehensive loss and no losses on debt securities available-for-sale have been recognized in income for the years ended December 31, 2024 and 2023. As of December 31, 2024 and 2023, there were no debt securities available-for-sale in a material unrealized loss position.

 Equity securities are comprised of investments in mutual funds. The fair value of equity securities at December 31, 2024 and 2023 were $ 1.2 million and $ 1.1 million, respectively. Unrealized losses or gains on equity securities recorded in income during the years ended December 31, 2024 and 2023 were as follows (in thousands):

 NOTE 8. DEFERRED REVENUE AND REMAINING PERFORMANCE OBLIGATIONS

 Deferred revenue consists of amounts received for products or services not yet delivered or earned. Deferred income consists of amounts received for commitments not yet fulfilled. When products or services are delivered to customers and as service commitments are fulfilled, these contract liabilities are recognized as earned. Deferred revenue or income that the Company does not expect will be earned within the following twelve months is reported in the consolidated balance sheets as deferred income, non-current.

 The Company recognized $ 0.5 million of revenue that was included in the beginning contract liabilities for each of the years ended December 31, 2024 and 2023. No material amount of revenue recognized during the period was from performance obligations satisfied in prior periods.

 Transaction Price Allocated to Remaining Performance Obligations

 As of December 31, 2024, $ 2.8 million of revenue is expected to be recognized from remaining performance obligations. This balance primarily relates to product shipments for reagents sold to customers under sales-type lease agreements. These agreements have between one - and six-year terms and revenue is recognized as reagents are shipped, typically on a straight-line basis. The remaining balance relates to executed service contracts that begin as warranty periods expire. These service contracts typically provide a one - to five-year term and revenue is recognized on a straight-line basis.

 The Company elects not to disclose the value of unsatisfied performance obligations for (i) contracts with an expected length of one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services performed.

 Commercial Agent Relationship with Becton, Dickinson and Company ("BD")
 The Company has entered into an exclusive commercial agreement with BD to act as the Company's agent and representative. The purpose of this agreement is to establish an ongoing commercialization of the Company's products. The Company is classified as the principal and BD as the agent. In accordance with the terms of this agreement, BD will pay the Company an exclusivity fee in multiple installments for exclusive rights, while the Company will pay BD an agent fee based on the Company's revenue.
 The Company accounts for agent fees consistent with how it accounts for sales commissions as described above in Note 2, Summary of Significant Accounting Policies. As such, agent fees paid to BD correspond with periodic sales and are expensed to sales, general and administrative expense.
 The Company accounts for the exclusivity fee from BD as a deferred income when the cash is received. The Company uses forecasted revenue to estimate the amount of deferred income to amortize within the period as an offset to sales, general and administrative expense.

 Australia R&D Tax Incentive

 As discussed further in Note 15, Income Taxes, in July 2023 and July 2024, the Company received a research and development tax incentive from Australia ("Australia R&D Tax Incentive") totaling $ 1.1 million $ 1.2 million, respectively, from the Australian government which is fully reserved as the sustainability of the respective amounts upon potential examination by the Australian tax authority is uncertain. These amounts, including any foreign exchange revaluations, are recorded as deferred income, non-current in the consolidated balance sheets as of December 31, 2024 and 2023.

 NOTE 10. NOTES PAYABLE

 16.00 % Notes

 On August 8, 2024, the Company entered into the Note Purchase Agreement with certain investors named therein pursuant to which the Company issued $ 15.0 million aggregate principal amount of the 16.00 % Notes.

 The carrying value of the 16.00 % Notes consisted of the following at December 31, 2024 (in thousands):

 The 16.00 % Notes will mature on December 31, 2025, and bear interest at a rate of 16.00 % per annum, payable in kind. Interest on the 16.00 % Notes is payable in kind by the Company quarterly in arrears on the last business day of each March, June, September and December, beginning on September 30, 2024.

 Interest expense related to the Company's 16.00 % Note obligation consisted of the following for the year ended December 31, 2024 (in thousands):

 2,281

 The effective interest rate on the 16.00 % Notes is 80.89 %. The Company may at any time redeem the 16.00 % Notes, in whole or in part, at a redemption price equal to the sum of the outstanding principal, all accrued and unpaid interest, and an applicable Exit Premium (as defined below).

 Contemporaneously with the Note Purchase Agreement, the Company also entered into an indenture, dated August 8, 2024 (the " 16.00 % Notes Indenture") with a trustee that provides that the 16.00 % Notes will be secured by a super-priority security interest in the same collateral that secures the Company's outstanding 5.00 % Notes. See Note 11, Convertible Notes, for additional detail.

 The 16.00 % Notes Indenture contains customary events of default. If an event of default (other than certain events of bankruptcy, insolvency or reorganization involving the Company) occurs and is continuing, the trustee, by notice to the Company, or the holders of the 16.00 % Notes representing at least a majority in aggregate principal amount of the outstanding 16.00 % Notes, by notice to the Company and the trustee, may declare 100.00 % of the principal of, the premium (including the Exit Premium) and all accrued and unpaid interest on, all of the then outstanding 16.00 % Notes to be due and payable immediately.

 Upon the occurrence of certain events of bankruptcy, insolvency or reorganization involving the Company, 100% of the principal, the premium (including the Exit Premium), and all accrued and unpaid interest on, all of the then outstanding 16.00 % Notes will automatically become immediately due and payable.

 Upon the occurrence of a change of control, the Company will be required to make an offer to repurchase all or any portion of the outstanding 16.00 % Notes at a price in cash equal to 100 % of the aggregate principal amount of the 16.00 % Notes repurchased, plus the premium (including the Exit Premium), and all accrued and unpaid interest to, but excluding, the date of repurchase.

 Upon the occurrence of any repayment (including at maturity or in connection with a change of control or an asset sale) or redemption or acceleration upon any event of default, the Company is required to pay the investors a fee equal to a certain percentage of the aggregate principal amount of the 16.00 % Notes then outstanding plus accrued and unpaid interest thereon, which fee shall be equal to 30.00 % if any such event occurs on or prior to June 30, 2025 and equal to 42.50 % if any such event occurs on July 1, 2025 and thereafter (the "Exit Premium"). The Company also contemporaneously entered into other customary ancillary agreements in connection with the issuance of the 16.00 % Notes.

 The 16.00 % Notes Indenture also contains various affirmative, negative and financial covenants that, among other things, may restrict the ability of the Company and its subsidiaries to incur additional indebtedness, create certain liens, merge or consolidate with another entity, pay dividends or repurchase stock, and sell all or substantially all of their assets.

 Repayment of the 16.00 % Notes inclusive of the Exit Premium resulted in the 16.00 % Notes being issued at a substantial discount. Accordingly, the associated prepayment contingencies were evaluated as an embedded feature of the 16.00 % Notes that requires bifurcation as a derivative liability. The fair value of the prepayment derivative liability was calculated using the "with and without" methodology at loan issuance. The "with and without" methodology involves valuing the term loan on an as-is basis and then valuing the term loan without the embedded derivative. As the Exit Premium is due on repayment regardless of contingency, there is nominal difference in the value of the term loan using the "with and without" methodology, and the derivative liability was determined to have no value as of issuance and as of December 31, 2024.

 NOTE 11. CONVERTIBLE NOTES

 The Company's convertible notes consisted of the 5.00 % Notes as of December 31, 2024, and the 2.50 % Notes and the 5.00 % Notes as of December 31, 2023.

 In March 2018, the Company issued $ 150.0 million aggregate principal amount of 2.50 % Notes. In connection with the offering of the 2.50 % Notes, the Company granted the initial purchasers of the notes a 13-day option to purchase up to an additional $ 22.5 million aggregate principal amount of the 2.50 % Notes on the same terms and conditions. In April 2018, the option was partially exercised, which resulted in $ 21.5 million of additional proceeds, for total proceeds of $ 171.5 million. The Company incurred issuance costs related to the issuance of the 2.50 % Notes which were amortized over the five-year contractual term of the 2.50 % Notes using the effective interest method until the maturity date of the 2.50 % Notes. The 2.50 % Notes matured on March 15, 2023 and became due and payable.

 In August 2022, the Company entered into an exchange agreement (the "August 2022 Exchange Agreement") with the Schuler Trust. Under the terms of the August 2022 Exchange Agreement, the Schuler Trust agreed to exchange with the Company $ 49.9 million in aggregate principal amount of 2.50 % Notes held by it for (a) the Secured Note with an aggregate principal amount of $ 34.9 million and (b) a warrant to acquire the Company's common stock (the "2022 Warrant") at an exercise price of $ 21.20 per share (the "Exercise Price"). See Note 12, Related Party Transactions, for additional information.

 In March 2023, the Company entered into the Forbearance Agreement with the Ad Hoc Noteholder Group holding approximately 85 % of the Company's outstanding 2.50 % Notes, the Trustee and any other owner of the 2.50 % Notes who executed and delivered to the Company a joinder to the Forbearance Agreement. Pursuant to the Forbearance Agreement, the members of the Ad Hoc Noteholder Group agreed, and directed the Trustee, to forbear from exercising their rights and remedies under the 2.50 % Notes Indenture in connection with certain events of default under the 2.50 % Notes Indenture, such as (i) failure to timely pay in full the principal of any 2.50 % Note when due and payable on March 15, 2023, (ii) failure to pay any interest on any 2.50 % Note when due and payable, (iii) failure to convert any 2.50 % Notes, (iv) default under any agreement with outstanding indebtedness for money borrowed in excess of $ 15.0 million and (v) any other breach, default or event of default under the 2.50 % Notes Indenture arising from the failure of the Company to timely pay in full the principal of any 2.50 % Note when due and payable on the maturity date for the 2.50 % Notes. The Forbearance Agreement was initially effective for the period commencing on March 13, 2023 and ending on April 21, 2023, the date of the Restructuring Support Agreement.

 The holders of the 2.50 % Notes that joined the Forbearance Agreement received a fee (the "Forbearance Premium") equal to $5.00 per $1,000 principal amount of the 2.50 % Notes held by such party, by executing and delivering a joinder to the Forbearance Agreement to the Company. During the year ended December 31, 2023, the Ad Hoc Noteholder Group received $ 0.2 million in Forbearance Premiums, which were capitalized and amortized as interest expense during the period commencing on March 13, 2023 through March 31, 2023.

 Restructuring Support Agreement and June 2023 Restructuring Transactions

 In April 2023, the Company entered into the Restructuring Support Agreement with certain holders of the 2.50 % Notes, the holder of the Secured Note and the holders of the Company's Series A Preferred Stock to negotiate in good faith to effect the restructuring of the Company's capital structure. In June 2023, the Company completed the Restructuring Transactions, contemplated by the Restructuring Support Agreement whereby the Company:
 • exchanged approximately $ 55.9 million, aggregate principal amount of the 2.50 % Notes for approximately $ 56.9 million aggregate principal amount of newly issued 5.00 % Notes, which was inclusive of additional 5.00 % Notes in respect of interest accrued on the 2.50 % Notes from September 15, 2022, of $ 1.0 million;
 • issued and sold an additional $ 10.0 million aggregate principal amount of 5.00 % Notes;
 • amended and repurchased the Secured Note, plus accrued interest, by issuing approximately 3.4 million shares of the Company's common stock;
 • issued approximately 0.4 million shares of the Company's common stock upon conversion of all of the Company's outstanding Series A Preferred Stock;
 • amended the securities purchase agreement that the Company entered into with the Schuler Trust in March 2022 (the "March 2022 Securities Purchase Agreement") and issued and sold approximately 0.5 million shares of the Company's common stock for proceeds of $ 4.0 million; and
 • entered into a purchase agreement with the Schuler Trust (the "Schuler Purchase Obligation") pursuant to which the Schuler Trust was required, prior to December 15, 2023 (which was subsequently amended and extended to February 15, 2024), to either purchase an aggregate $ 10.0 million of the Company's common stock from the Company or to backstop an underwritten public offering by the Company of its common stock for aggregate proceeds of $ 10.0 million, at the Company's option. Further details regarding the Secured Note, March 2022 Securities Purchase Agreement, Series A Preferred Stock and Schuler Purchase Obligation are included in Note 12, Related Party Transactions.

 The exchange of the 2.50 % Notes for the 5.00 % Notes, as described above, and associated accrued interest was accounted for as an extinguishment of debt under ASC 470-50-40. Under extinguishment accounting, the 2.50 % Notes were derecognized and the new instruments, which included the 5.00 % Notes and a bifurcated Conversion Option were recorded at their respective fair values. The extinguishment of the 2.50 % Notes resulted in a loss of $ 6.6 million for the year ended December 31, 2023. See further discussion of the 5.00 % Notes below.

 In April 2024, the Company settled the outstanding balance of its 2.50 % Notes. The payment of approximately $ 0.8 million satisfied all outstanding principal and accrued interest remaining on the 2.50 % Notes.

 As a result of the Restructuring Transactions, the Company recorded at fair value approximately $ 56.9 million aggregate principal amount of newly issued 5.00 % Notes in its consolidated balance sheets in June 2023. In addition, the Company issued an additional $ 10.0 million aggregate principal amount of 5.00 % Notes, for cash proceeds with certain existing note holders as part of the Restructuring Transactions. On the December 15, 2026 maturity date, outstanding principal will be due for all remaining outstanding 5.00 % Notes.

 The 5.00 % Notes bear interest at a rate of 5.00 % per annum. The Company pays interest on the 5.00 % Notes by payment-in-kind ("PIK"), through the issuance of additional 5.00 % Notes (" 5.00 % PIK Notes"). The amount is paid to holders by increasing the principal amount of each outstanding 5.00 % Note by an amount equal to the interest payable for the applicable interest period. The Company calculates PIK interest semi-annually on June 15 and December 15, on a compound basis based on the stated rate of 5.00 %.

 The 5.00 % Notes are secured by substantially all of the assets of the Company and its subsidiaries.
 Redeeming the 5.00 % Notes before June 15, 2025 could trigger a "Make-Whole Fundamental Change" as defined in the indenture governing the 5.00 % Notes (the " 5.00 % Notes Indenture"). On or after June 15, 2025, the Company may, at its option, redeem for cash all or a portion of the 5.00 % Notes.
 Upon issuance of the 5.00 % Notes, each holder has a Conversion Option, which represented the right at their option, to convert any portion of their notes at an initial conversion rate of 138.88889 shares of common stock per $1,000 of principal amount (the "Initial Conversion Rate"). Effective October 18, 2023, the Initial Conversion Rate was to be adjusted to a conversion rate calculated based on a conversion price of $ 7.20 per share of common stock plus 50 % of the difference between the Post-Closing VWAP (as defined in the 5.00 % Notes Indenture) and $ 7.20 (if such difference is a positive number), provided that in no event will the adjusted conversion rate be lower than 120.48193 per $1,000 principal amount of the 5.00 % Notes, based on a conversion price of $ 8.30 per share of common stock. The Company evaluated the conversion rate per the terms outlined above and determined the Initial Conversion Rate of 138.88889 shares of common stock per $1,000 principal amount will continue to be the conversion rate through the remaining term of the 5.00 % Notes (the "Fixed Conversion Rate"). The Company cannot require the holders of the 5.00 % Notes to convert at any time but when a holder exercises their Conversion Option, the Company can settle in cash, shares of common stock or a combination of cash and shares of common stock, at the Company's election.
 Management determined the Conversion Option met the derivative bifurcation criteria under ASC 815 at inception through October 17, 2023, the date at which the conversion rate became fixed. During that period the derivative instrument was bifurcated and adjusted to fair value through earnings, using Level 3 inputs, at each reporting date with a final mark-to-market adjustment once the Conversion Option became fixed at the end of the day on October 17, 2023 and no longer met the bifurcation criteria. The fair value of the Conversion Option and a derivative liability of $ 38.2 million as of the transaction date was recorded as a debt issuance discount at inception. The Company also incurred issuance costs of $ 3.0 million. The debt premium, debt discount and debt issuance costs are being amortized using the effective interest method over the 3.5 year contractual term of the 5.00 % Notes. The effective interest rate on the 5.00 % Notes as of December 31, 2024 and 2023 is 27.56 % and 27.30 %, respectively. As of December 31, 2024, the number of shares of common stock issuable upon conversion of the 5.00 % Notes was 9.9 million shares, based on the Fixed Conversion Rate.
 Holders of the 5.00 % Notes who convert their notes in connection with a Make-Whole Fundamental Change are, under certain circumstances, entitled to an increase in the conversion rate. If a fundamental change occurs at any time prior to the maturity date of the 5.00 % Notes, each holder will have the right, at such holder's option, to require the Company to repurchase for cash all of such holder's 5.00 % Notes, at a repurchase price equal to 100 % of the principal amount thereof, plus accrued and unpaid interest.
 During the period from inception through October 17, 2023, the bifurcated Conversion Option was adjusted to fair value through earnings within Gain on fair value adjustment on the statement of operations and the statement of cash flows, using Level 3 inputs, at each reporting date with a final mark-to-market adjustment once the Conversion Option became fixed at the end of the day on October 17, 2023 and no longer met the bifurcation criteria.

 The derivative financial instrument was derecognized as of October 17, 2023, and the fair value of the instrument as of that date was moved to contributed capital in the consolidated balance sheet.
 In August 2023, certain holders of the 5.00 % Notes opted to convert approximately $ 0.7 million aggregate principal amount of 5.00 % Notes for approximately 94,000 shares of the Company's common stock at the Initial Conversion Rate (the "Initial Conversion Rate Conversions").
 Subsequent Conversion Option transactions were at the Fixed Conversion Rate (the "Fixed Conversion Rate Conversions") and include $ 0.3 million aggregate principal amount of 5.00 % Notes converted for approximately 39,000 shares of the Company's common stock for the year ended December 31, 2023 and $ 0.1 million aggregate principal amount of 5.00 % Notes converted for approximately 11,000 shares of the Company's common stock for the year ended December 31, 2024.
 Under ASC 470-50-40, the Initial Conversion Rate Conversions qualified as an extinguishment. These conversions of 5.00 % Notes were included within the bifurcated Conversion Option classified as a derivative liability. Upon the Initial Conversion Rate Conversions, the 5.00 % Notes and the derivative liability were derecognized at their carrying amounts and the common stock was measured at its then-current fair value, with the difference recorded as a gain on the extinguishment of the applicable liability. The value of the shares of common stock issued in connection with Fixed Conversion Rate Conversions was recorded to contributed capital.
 The net carrying value of the 5.00 % Notes derecognized as part of the Initial Conversion Rate Conversions, the 2023 Fixed Conversion Rate Conversions and 2024 Fixed Conversion Rate Conversions was $ 0.7 million, $ 0.3 million, and $ 0.1 million, respectively. The carrying amount of the derivative liability, which was carried at fair value, derecognized as part of the Initial Conversion Rate Conversions was $ 0.4 million. The Initial Conversion Rate Conversions resulted in a gain on extinguishment of debt of $ 0.1 million for the year ended December 31, 2023.
 The 5.00 % Notes represent an instrument measured at fair value on a non-recurring basis using Level 3 inputs. The estimated fair value of the 5.00 % Notes on June 9, 2023, the initial measurement, date was $ 38.2 million, which included a $ 6.0 million debt premium.
 As of December 31, 2024, the 5.00 % Notes are carried at amortized cost with an estimated fair value of $ 54.8 million. The following table summarizes the significant inputs used to estimate the fair value of the 5.00 % Notes as of December 31, 2024, December 31, 2023 and the June 9, 2023 issuance date:

 The volatility used to estimate the fair value of the 5.00 % Notes is an unobservable input. As volatility is an estimate, there is a range of values that could be considered appropriate. Changes to this input could impact the fair value reported.

 During the years ended December 31, 2024 and 2023, the Company issued $ 3.4 million and $ 1.7 million aggregate principal amount of 5.00 % PIK Notes, respectively, to pay interest accrued on the 5.00 % Notes outstanding for such periods.

 As of both December 31, 2024 and 2023, $ 0.1 million of accrued interest related to the 5.00 % Notes is included on the consolidated balance sheets.

 Fair Value of Conversion Option

 The Company's Conversion Option was classified as a derivative financial instrument and carried at fair value using Level 3 inputs from the date of inception until the conversion price became fixed on October 17, 2023. To determine the fair value of the Conversion Option, the Company calculated the difference in the value of the 5.00 % Notes with and without the Conversion Option. The estimated fair value of the Conversion Option as of October 17, 2023 was $ 26.9 million. The fair value of the Conversion Option was estimated using a Monte Carlo simulation. For each path, the Company simulated the stock price over time such that:

 • The Company determined the 60-day average stock price to calculate the conversion price.

 • At each date after the call option start date, the Company used a Tsiveriotis and Fernandes model to determine the continuation value and compare it to a call price. If the continuation value exceeds the call price, the Company assumed exercise of the call option. When the call option is exercised, the holders will receive the maximum of the conversion value or the call price.

 • The valuation also considered the reset conversion price as well as the accrued PIK. The Company determined whether the holder elects to convert the 5.00 % Notes at the maturity date for the simulation paths where the 5.00 % Notes has not been called prior to such date.

 The following table summarizes the significant inputs used to estimate the fair value of the Conversion Option as of October 17, 2023 and June 9, 2023:

 NOTE 12. RELATED PARTY TRANSACTIONS

 March 2022 Securities Purchase Agreement

 In March 2022, the Company entered into the March 2022 Securities Purchase Agreement with the Schuler Trust for the issuance and sale by the Company of an aggregate of approximately 0.2 million shares of the Company's common stock to the Schuler Trust in an offering (the "2022 Private Placement") exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, and Rule 506 promulgated

 thereunder. Pursuant to the March 2022 Securities Purchase Agreement, the Schuler Trust agreed to purchase the shares at a purchase price (determined in accordance with Nasdaq rules relating to the "market value" of the Company's common stock) of $ 16.40 per share, for an aggregate purchase price of $ 4.0 million. In March 2022, the Company classified the March 2022 Securities Purchase Agreement as an equity forward agreement that met the definition of a freestanding derivative financial instrument initially classified in stockholders' deficit. The value of this equity forward agreement was considered immaterial at inception.
 The Company and the Schuler Trust agreed to extend the closing date of the March 2022 Securities Purchase Agreement several times under the original terms of the 2022 Private Placement. As discussed in Note 11, Convertible Notes, in June 2023, the Company and the Schuler Trust amended the March 2022 Securities Purchase Agreement, which changed the terms of settlement. The amendment changed the closing date to June 9, 2023, amended the price per share from $ 16.40 to $ 8.20, upon which the Company issued approximately 0.5 million shares of common stock to the Schuler Trust for the same proceeds of $ 4.0 million.
 The Company determined the amendment was a modification of a freestanding equity classified financial instrument. The share price change from $ 16.40 to $ 8.20, with no changes to the total proceeds of $ 4.0 million, resulted in the Schuler Trust receiving approximately 0.2 million more shares than the Schuler Trust would have received prior to the modification. The closing price of the Company's common stock on June 9, 2023, the date of the modification, was $ 7.40 and was used to estimate the fair value of the additional common stock issued. The fair value of the additional shares issued was $ 1.8 million, which was recorded to loss on extinguishment of debt with related party on the consolidated statements of operations and comprehensive loss.
 August 2022 Exchange Agreement
 In August 2022, the Company entered into the August 2022 Exchange Agreement with the Schuler Trust. Under the terms of the August 2022 Exchange Agreement, the Schuler Trust agreed to exchange with the Company $ 49.9 million in aggregate principal amount of 2.50 % Notes held by it for the Secured Note and the 2022 Warrant. See Note 11, Convertible Notes, for additional information regarding the 2.50 % Notes.
 The Secured Note had a scheduled maturity date of August 15, 2027 and was repayable upon written demand any time on or after such date. The Company could, at its option, repay the Secured Note in (i) cash or (ii) in the form of common stock of the Company, in a number of shares that is obtained by dividing the total amount of such payment by $ 21.20. As noted under "Secured Note Amendment and Exchange" below, the Secured Note was extinguished in June 2023, resulting in a carrying value of the Secured Note of $ 0 as of December 31, 2023.
 The 2022 Warrant may be exercised through the earlier of (i) August 15, 2029 and (ii) the consummation of certain acquisition transactions involving the Company, as set forth in the 2022 Warrant. The 2022 Warrant is exercisable for up to 247,171 shares of the Company's common stock and may be exercised in whole or in part at any time during the exercise period. Such number of shares and the Exercise Price are subject to certain customary proportional adjustments for fundamental events, including stock splits and recapitalizations, as set forth in the 2022 Warrant. The Company determined that the 2022 Warrant meets the criteria for classification in stockholders' equity and was recorded in equity and initially measured at fair value on the issuance date. The fair value of the 2022 Warrant at issuance was $ 3.8 million and was estimated using the Black-Scholes option pricing model. The fair value of the 2022 Warrant is a non-recurring measurement that is categorized as Level 3 within the fair value hierarchy as it is based on Level 2 and Level 3 inputs. No portion of the 2022 Warrant has been exercised as of December 31, 2024.
 Conversion of Series A Preferred Stock to Common Stock

 In September 2021, the Company entered into a securities purchase agreement with the Tanya Eva Schuler Trust, the Therese Heidi Schuler Trust and Schuler Grandchildren LLC (collectively, the "Schuler Purchasers") for the issuance and sale by the Company of an aggregate of approximately 4.0 million shares of the Company's Series A Preferred Stock, par value $ 0.001 per share (the "Series A Preferred Shares") at a purchase price of $ 7.70 per share for an aggregate purchase price of approximately $ 30.5 million, which was recorded to contributed capital when it was received in 2022. Each share of Series A Preferred Shares was convertible, at the option of the holder, into one share of the Company's common stock.

 As discussed in Note 11, Convertible Notes, the Schuler Purchasers exercised their right to convert a total of approximately 4.0 million shares of Series A Preferred Shares to approximately 0.4 million shares of the Company's common stock. All of the Company's Series A Preferred Shares were converted into common stock as part of the Restructuring Transactions, and no Series A Preferred Shares remained outstanding as of December 31, 2023 and 2024. During the year ended December 31, 2023, the amounts associated with the Series A Preferred Shares were reclassified to common stock and contributed capital as presented in the consolidated statements of stockholders' deficit.

 Secured Note Amendment and Exchange

 As discussed in Note 11, Convertible Notes, as part of the Restructuring Transactions, the Company and the Schuler Trust amended the Secured Note (the "Secured Note Amendment"), which changed the settlement provisions of the Secured Note. Pursuant to the Secured Note Amendment, the share conversion price was changed from $ 21.20 to $ 10.60, and the Secured Note was contemporaneously settled through the Company's issuance of approximately 3.4 million shares of its common stock.

 The transaction qualified as an extinguishment of debt, and the reacquisition price of the extinguished debt was determined to be the fair value of the common stock issued in the transaction. The closing price of the Company's common stock on June 9, 2023, the date of the extinguishment, was $ 7.40 and was used to estimate the fair value of the common stock, which was $ 25.4 million. The carrying amount of the Secured Note and associated accrued interest being extinguished was determined to be $ 19.3 million. This resulted in a net loss on extinguishment of $ 6.1 million, which was recorded to loss on extinguishment of debt with related party in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2023.

 Schuler Purchase Obligation
 In June 2023, the Company entered into the Schuler Purchase Obligation with the Schuler Trust pursuant to which the Schuler Trust was required, at the Company's option, to either purchase approximately 1.4 million shares of common stock from the Company valued at $ 7.20 per share for an aggregate purchase price of $ 10.0 million or to backstop a public offering by the Company of common stock for aggregate proceeds of $ 10.0 million. If the Company elected to conduct a public offering of common stock and other investors purchased less than $ 10.0 million of common stock by December 15, 2023, the Schuler Trust would have the obligation to purchase $ 10.0 million of shares of common stock, less the amount of common stock purchased by other investors, and would have the right to purchase additional shares of common stock such that the total amount of common stock purchased by the Schuler Trust equaled $ 10.0 million of shares of common stock. If the Company elected to conduct a public offering of common stock and other investors purchased $ 10.0 million of shares of common stock by December 15, 2023, the Schuler Trust would have the right, but not the obligation, to purchase up to $ 10.0 million of shares of common stock at the public offering price for the backstopped offering up to a maximum aggregate purchase by the Schuler Trust of $ 10.0 million of common stock.
 In December 2023, the Company and the Schuler Trust entered into an amendment to the Schuler Purchase Obligation extending the deadline for the investment or public offering backstop through February 15, 2024 and the Schuler Trust agreed to purchase $ 2.0 million at the public offering price if the aggregate gross proceeds to the Company resulting from the public offering was more than $ 10.0 million.
 Management determined the Schuler Purchase Obligation met the criteria of a freestanding financial instrument at inception. The Schuler Purchase Obligation was recorded as an asset at fair value to be marked to market at each reporting period. At inception, the value of the Schuler Purchase Obligation was $ 1.3 million, which was recorded as an offset to loss on extinguishment of debt with related party on the consolidated statements of operations and comprehensive loss.
 At December 31, 2023, it was determined that the fair value of the Schuler Purchase Obligation financial instrument was $ 3.4 million. Changes in the fair value of the Schuler Purchase Obligation are recognized in (loss) gain on fair value adjustment, within the consolidated statements of operations and comprehensive loss. The recognized gain on fair value adjustment on financial instruments related to the Schuler Purchase Obligation for the year ended December 31, 2023 was $ 2.1 million.

 To determine the fair value of the Schuler Purchase Obligation, the Company used a Cox-Ross-Rubinstein binomial tree model to value the American put option. The following table summarizes the significant inputs used to estimate the fair value of the Schuler Purchase Obligation as of December 31, 2023 and June 9, 2023:

 The volatility and obligation probability used to quantify the fair value of the Schuler Purchase Obligation are unobservable inputs, and because these are estimates, there are a range of values that could be considered appropriate, which could impact the fair value reported. In determining the obligation probability, the Company assessed the likelihood that the Schuler Purchase Obligation would be utilized to either sell common shares or backstop a public offering. Given the equity market environment as of December 31, 2023 and the significant number of unknowns that would lead to either a successful or unsuccessful conclusion of a public offering, the Company estimated the likelihood of such obligation probability at 75 %. There were significant judgments, assumptions and estimates inherent in the determination of the fair value of the Schuler Purchase Obligation, which included determination of valuation method, selection of inputs, and assessment of possible outcomes. The valuation approach used and inputs described above may have a greater or lesser impact on the Company's estimate of fair value. See Note 4, Fair Value of Financial Instruments, for additional information.
 As discussed further in Note 18, Stockholders' Deficit, the Company completed the January 2024 Public Units Offering for $ 10.2 million of gross proceeds in January 2024.

 As a result, the Schuler Trust was not required to backstop the offering in accordance with the Schuler Purchase Obligation. Upon completion of the January 2024 Public Units Offering, the fair value of the Schuler Purchase Obligation financial instrument was eliminated resulting in a loss on fair value adjustment of $ 3.4 million during the year ended December 31, 2024. Concurrently with the completion of the January 2024 Public Units Offering, Units were sold to the Schuler Trust, the Company's Chief Executive Officer and Chief Financial Officer in a private placement offering in January 2024. Pursuant to the subscription agreement entered into between the Schuler Trust and the Company in connection with the private placement offering of Units, additional Units were also sold to the Schuler Trust in May 2024. Additional information regarding the offerings of Units is included in Note 18, Stockholders' Deficit.

 NOTE 13. LOSS PER SHARE

 Basic net loss per common share was determined by dividing net loss applicable to common stockholders by the weighted average common shares outstanding during the period (including shares underlying Pre-Funded Warrants with only nominal cost to exercise). Basic and diluted net loss per share are the same because all outstanding common stock equivalents have been excluded, as they are anti-dilutive due to the Company's losses.

 The following potentially issuable common shares were not included in the computation of diluted net loss per share because they would have an anti-dilutive effect due to net losses for the years ended December 31 (in thousands):

 2023

 Shares issuable upon the release of RSUs

 5.00 % Notes
 As discussed in Note 11, Convertible Notes, each holder of the 5.00 % Notes has the right at their option, to convert any portion of the 5.00 % Notes at the Fixed Conversion Rate of 138.88889 shares of common stock per $1,000 principal amount of the 5.00 % Notes. Holders of the 5.00 % Notes who convert their 5.00 % Notes in connection with a Make-Whole Fundamental Change are, under certain circumstances, entitled to an increase in the conversion rate. The number of shares of common stock issuable upon conversion of the 5.00 % Notes as of December 31, 2024 based on the Fixed Conversion Rate is 9.9 million, convertible at the holders' option. There were 9.4 million shares of common stock issuable upon conversion of the 5.00 % Notes as of December 31, 2023. These shares were not included in the computation of diluted net loss per share because they would have an anti-dilutive effect.

 NOTE 14. EQUITY-BASED COMPENSATION

 The Company has one equity-based compensation plan as of December 31, 2024. This plan, the 2022 Omnibus Incentive Compensation Plan ("2022 Incentive Plan"), was adopted by the Company's Board of Directors upon approval by the Company's stockholders in May 2022. Upon adoption, the Company's previous 2012 Omnibus Equity Incentive Plan (the "2012 Incentive Plan") was automatically replaced and superseded by the 2022 Incentive Plan. Outstanding awards granted under the 2012 Incentive Plan remain in effect pursuant to their terms with vesting periods ranging from immediate to five years with a maximum contractual term of ten years.

 Upon adoption in May 2022, the total number of shares of the Company's common stock reserved and available for grant pursuant to the 2022 Incentive Plan was 0.6 million plus shares of common stock that remain available or that otherwise become available for grant under the 2012 Incentive Plan. At the Company's 2023 Annual Meeting of Stockholders and 2024 Annual Meeting of Stockholders, the Company's stockholders approved an additional 1.6 million and 4.0 million shares of common stock, respectively, reserved and available for grant under the 2022 Incentive Plan. As of December 31, 2024, the total number of shares reserved for the 2022 Incentive Plan is 7.3 million.

 Stock options granted under the 2022 Incentive Plan vest in three years with a maximum contractual term of ten years while RSUs granted under this plan vest in a range from immediate to five years. The total number of shares of the Company's common stock reserved and available for grant pursuant to the 2022 Incentive Plan as of

 December 31, 2024 is 2.4 million.

 As of December 31, 2024, unrecognized equity-based compensation cost related to unvested stock options and unvested RSUs was $ 0.1 million and $ 3.6 million, respectively. This is expected to be recognized over the years 2025 through 2028 with a weighted average period of 1.9 years.

 Included in the above-noted RSU outstanding amount are performance-based RSUs which vest only upon the achievement of certain targets. Performance-based RSUs contingently vest over a period of 19 months and have contractual lives of 10 years. These units were valued in the same manner as other RSUs, based on the published closing market price on the day before the grant date. However, the Company only recognizes stock compensation expense to the extent that the targets are determined to be probable of being achieved, which triggers the vesting of the performance-based RSUs.

 For the year ended December 31, 2024, the Company granted 1.3 million performance-based RSUs and no performance-based RSUs were released due to the performance obligations being achieved. As of December 31, 2024, 1.3 million performance-based RSUs were outstanding. None of these performance-based RSU have been forfeited due to performance obligations not being achieved, while 60,000 performance-based RSUs were forfeited due to employee attrition.

 No material expense for performance-based RSUs was recognized during the years ended December 31, 2024 and 2023.

 As of December 31, 2024, the Company generated regular tax federal net operating losses ("NOLs") of approximately $ 403.1 million net of limitation under Section 382 of the Internal Revenue Code of 1986 ("Section 382"). As a result of the Tax and Jobs Act, for U.S. income tax purposes, NOLs generated prior to December 31, 2017 can be carried forward for up to 20 years. Of the Company's total federal NOLs of $ 403.1 million, $ 156.9 million will begin to expire in 2025 and $ 246.2 million will not expire but will only offset 80% of taxable income generated in tax years after 2017.

 As of December 31, 2024, the Company has generated state NOLs of approximately $ 398.2 million. The Company's state NOLs will begin to expire in 2030.

 As of December 31, 2024, the Company has generated $ 16.2 million of federal research and development ("R&D") tax credits which begin to expire in 2032.

 As of December 31, 2024, the Company has generated $ 14.2 million of state R&D tax credits which begin to expire in 2031.

 Utilization of the Company's NOL and R&D credit carryforwards may be subject to a substantial annual limitation due to ownership change limitations that have occurred previously or that could occur in the future in accordance with Section 382 as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and taxes, respectively. In general, an ownership change as defined by Section 382 results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than 50% over a three-year period. The Company has not conducted a comprehensive study to assess whether a change of control has occurred or whether there have been multiple changes of control since inception due to significant complexity with such a study. If the Company has experienced a change of control, as defined by Section 382, at any time since inception, utilization of the NOL or R&D credit carryforward would be subject to an annual limitation under Section 382. Since the Company has not completed its comprehensive analysis, it is reasonably possible that its federal and

 state NOLs, and R&D credits available to offset future taxable income could materially decrease. This reduction would be offset by an equal and offsetting adjustment to the existing valuation allowance. Any limitation may result in expiration of a portion of the NOL or R&D credit carryforward before utilization.

 The net deferred tax asset valuation allowance is $ 150.3 million as of December 31, 2024, compared to $ 140.1 million as of December 31, 2023. The valuation allowance is based on management's assessment that it is more likely than not that the Company will not have taxable income in the foreseeable future. Due to the Company's consolidated loss position, the Company maintains a valuation allowance against its deferred tax assets. The change in the Company's valuation allowance during 2024 of $ 10.2 million is comprised of an increase of $ 10.8 million in deferred tax expense and $ 0.7 million in other comprehensive loss.

 As discussed in Note 11, Convertible Notes, in June 2023 the Company entered into a series of agreements with certain holders of the 2.50 % Notes, the Schuler Trust, and the holders of the Company's Series A Preferred Stock to effect the Restructuring Transactions. The consummation of the Restructuring Transactions resulted in, among other things, the Company exchanging $ 55.9 million aggregate amount of principal 2.50 % Notes for $ 56.9 million aggregate principal amount of newly issued 5.00 % Notes including an additional 5.00 % Notes for the accrued interest on the 2.50 % Notes exchanged of approximately $ 1.0 million. The Company accounted for the transaction as an extinguishment of debt and recognized a loss of $ 14.1 million for the year ended December 31, 2023 which is not deductible for income tax purposes. In addition, the Company issued and sold an additional $ 10 million aggregate principal amount of 5.00 % Notes in the Restructuring Transactions.

 The Company determined that the 5.00 % Notes included an embedded derivative related to the conversion option which was accounted for as a derivative liability and related debt discount of $ 38.2 million. The Company recorded a deferred tax asset of $ 9.5 million and a deferred tax liability of $ 9.5 million for the embedded derivative liability and debt discount, respectively, upon issuance. The Company marked the derivative liability to market through October 17, 2023, the date at which the conversion price for the 5.00 % Notes became fixed, at which time the derivative liability was reclassed to equity. The deferred tax asset related to the derivative liability of $ 6.8 million, which was fully offset by a valuation allowance, was reversed at that time and had no impact on the effective tax rate.

 The Company began commercialization of its products in Europe in 2016 and has subsidiaries in the Netherlands, Australia, France, Germany, Italy, Spain, and the United Kingdom. The Company intends to treat earnings from its foreign subsidiaries as permanently reinvested.

 These uncertain positions are not expected to change within the next twelve months. No amount of the $ 9.1 million of uncertain tax positions would impact the effective tax rate, if reversed. The Company accounts for interest and penalties on uncertain tax positions within tax expense. During the year ended December 31, 2024, the Company recognized no material amount of interest and penalties in the consolidated statements of operations and comprehensive loss. During the year ended December 31, 2023, the Company recognized $ 0.1 million in interest and penalties in the consolidated statements of operations and comprehensive loss. The Company had no material amount accrued for the payment of interest and penalties at December 31, 2024. The Company had $ 0.1 million for the payment of interest and penalties accrued at December 31, 2023. The Company incurred net operating losses since inception that are subject to adjustment under IRS and state examination. The Company's foreign subsidiaries are generally subject to applicable jurisdiction examination for all years of operations. The Company has adequate tax attributes available to utilize against its uncertain tax positions in a given year.

 The Company incurred NOLs since inception that are subject to adjustment under Internal Revenue Service ("IRS") and state examination. In the first quarter of 2021, the Company was informed by the IRS that they would begin an examination of the Company's 2018 tax year. The Company substantially completed the IRS audit of the 2018 tax year during 2021. The IRS assessed adjustments reducing the Company's 2018 R&D tax credit and 2018 NOL. The Company has removed the associated reserve for uncertain tax benefits during the year ended December 31, 2022 and adjusted the deferred tax asset for the NOL and R&D credit carryforwards as a result of the audit settlement. No cash taxes, interest or penalties were paid in connection with this settlement. During the year ended December 31, 2022, the Company increased its reserve for uncertain tax positions in connection with the exchange of debt. The Company's foreign income tax filings are subject to examination by the appropriate foreign tax authorities. The Company is not otherwise currently under examination by tax authorities.

 Australia R&D Tax Incentive

 The Australian government offers an R&D tax incentive to help companies conducting eligible R&D activities in Australia in the form of refundable tax credits if certain conditions are met. Management assesses the Company's R&D activities and expenditures to determine which activities and expenditures are likely to be eligible under the tax incentive regime. Annually, management estimates refundable tax credit available to the Company based on available information and submits an application to the Australian tax authority for R&D credit approval. The Company recognizes the refundable R&D tax credits when there is reasonable assurance that the terms have been met, income will be received, the relevant expenditure has been incurred and the consideration can be reliably measured. The refundable R&D tax credit is recorded as a reduction to research and development expense in the consolidated statements of operations and comprehensive loss when the aforementioned criteria are met. In July 2023, the Company received a $ 1.1 million refundable R&D tax credit for its 2022 R&D activities in Australia. In July 2024, the Company received a $ 1.2 million refundable R&D tax credit for its 2023 R&D activities in Australia. The Company provided for a full reserve against the credits as sustainability of the credit upon potential examination by the Australian tax authority is uncertain. The Company does not currently believe it is probable that any penalties or interest will be assessed to the extent that the credit is not sustained.

 NOTE 16. COMMITMENTS AND CONTINGENCIES

 In April 2022, the Company entered into a non-cancellable purchase obligation with a supplier to acquire raw materials related to the development and commercialization of its next generation Accelerate WAVE system for a total commitment of $ 11.9 million. Under the terms of this agreement, the Company has until March 15, 2027 to take delivery of purchased items.

 As of December 31, 2024, the commitment remains $ 11.9 million as the Company has not taken delivery of any of the related inventory.

 NOTE 17. SEGMENT, GEOGRAPHIC AND REVENUE DISAGGREGATION

 The Company operates as one operating segment, deriving instrument, consumable, and service revenues from customers engaged in healthcare diagnostics primarily within the United States. Product revenue is derived from the sale or rental of instruments and sales of related consumable products. Service revenue is derived from the sale of extended service agreements.

 The chief operating decision maker (CODM), our President and Chief Executive Officer and Chief Financial Officer, assesses performance on a consolidated basis and decides how to allocate resources based on consolidated net loss as presented on the Company's consolidated statements of operations and comprehensive loss predominantly in the annual budgeting and forecasting process.

 Given the Company operates as one segment, segment net sales, profit and loss, and total assets is consistent with consolidated net sales, profits and losses, and total assets as presented on the Company's consolidated statements of operations and comprehensive loss and balance sheets as of and for the years ended December 31, 2024 and 2023. The Company's significant segment expenses are consistent with those presented on the Company's consolidated statements of operations and comprehensive loss for the years ended December 31, 2024 and 2023.

 Sales to customers outside the U.S. represented 11 % and 12 % of net sales for the years ended December 31, 2024 and 2023, respectively. As of December 31, 2024 and 2023, accounts receivable balances due from these foreign customers, in U.S. dollars, were $ 0.5 million and $ 0.9 million, respectively.

This income does not represent revenue recognized from contracts with customers in accordance with ASC 606.

 NOTE 18. STOCKHOLDERS' DEFICIT

 The Company has entered into a number of securities purchase and exchange agreements with affiliated and external parties throughout its history, and has provided equity-based compensation to its employees, directors and affiliated parties. See Note 11, Convertible Notes, Note 12, Related Party Transactions, and Note 14, Equity-Based Compensation, for further discussion of transactions impacting the Company's stockholders' deficit for the years ended December 31, 2024 and 2023.

 January 2024 Units Offering

 In January 2024, the Company completed the January 2024 Public Units Offering consisting of 6.8 million units (the "Units"), each consisting of one share of common stock and one warrant to purchase one share of common stock (each, a "Common Warrant"), and for certain investors in lieu thereof, pre-funded Units (the "Pre-Funded Units"), each consisting of one pre-funded warrant to purchase one share of common stock (each, a "Pre-funded Warrant"), and one Common Warrant to purchase one share of common stock. The public offering price for each Unit was $ 1.50 and the public offering price for each Pre-Funded Unit was $ 1.49.

 The Company granted the underwriters for the January 2024 Public Units Offering a 30 -day option to purchase up to an additional 1.0 million shares of common stock and/or additional Common Warrants to purchase up to 1.0 million shares of common stock, in any combination thereof, at the public offering price, less underwriting discounts and commissions. The underwriters elected to purchase an additional 36,003 Common Warrants from the Company under this option.

 Common Warrants issued to investors in the January 2024 Public Units Offering have an exercise price of $ 1.65 per share, were immediately exercisable upon issuance and will remain exercisable until the date that is five years after their original issuance. The Pre-Funded Warrants have an exercise price of $ 0.01 per share, are immediately exercisable and will remain exercisable until exercised in full. The gross proceeds from the January 2024 Public Units Offering, before deducting underwriting discounts and commissions and other public offering expenses payable by the Company were approximately $ 10.2 million (excluding any proceeds that may be received upon the exercise of the Common Warrants or the Pre-Funded Warrants).

 Concurrently with the completion of the January 2024 Public Units Offering, the Company sold 1.2 million Units at a purchase price of $ 1.73 per Unit to the Schuler Trust, which satisfied the Schuler Purchase Obligation and an aggregate of 33,332 Units at a purchase price of $ 1.50 per Unit to the Company's Chief Executive Officer and Chief Financial Officer, in each case, in a private placement offering. The gross proceeds from the private placement offering, before deducting underwriting discounts and commissions and other expenses payable by the Company, were approximately $ 2.0 million (excluding any proceeds that may be received upon the exercise of the Common Warrants).

 Pursuant to the subscription agreement entered into between the Schuler Trust and the Company in connection with the private placement offering of Units, the Schuler Trust also agreed to purchase an additional 1.6 million Units at a purchase price of $ 1.73 per Unit on or before May 20, 2024 (the "Forward Contract"). On May

 20, 2024, the Company completed the sale of such additional Units to the Schuler Trust for gross proceeds of approximately $ 2.7 million (before deducting underwriting discounts and commissions and other expenses payable by the Company and excluding any proceeds that may be received upon the exercise of the Common Warrants).

 Aggregate net proceeds from the January 2024 Public Units Offering and private placement offering of Units (including the additional Units purchased by the Schuler Trust in May 2024) for the year ended December 31, 2024 were approximately $ 13.7 million.

 The Company evaluated the Pre-Funded Warrants to determine whether they are equity-classified or liability-classified instruments. The Company concluded that the Pre-Funded Warrants are indexed to the Company's own stock and meet all other criteria for equity classification. Therefore, the Pre-Funded Warrants were recorded in contributed capital on the consolidated statements of stockholders' deficit.

 The Company also evaluated the Common Warrants and Forward Contract to determine whether they are equity-classified or liability-classified instruments. The Company concluded that the Common Warrants and Forward Contract are not indexed to the Company's own stock and are therefore liability-classified. The Company further determined the Common Warrants and Forward Contract meet the definition of a derivative instrument and do not qualify for any scope exceptions to derivative accounting. Therefore, the Common Warrants and Forward Contract were initially recorded at fair value and are subsequently remeasured at fair value as of each reporting date.

 Proceeds from the January 2024 Public Units Offering were first allocated to the liability-classified instruments based on their fair value with the residual proceeds allocated to the equity-classified instruments based on their relative fair values. Transaction expenses were allocated among the equity-classified and liability-classified instruments. Those transaction expenses allocated to the equity-classified instruments were recorded as an offset to the proceeds in contributed capital on the consolidated statements of stockholders' deficit. Those transaction expenses allocated to the liability-classified instruments were recorded to other expense on the consolidated statements of operations and comprehensive loss.

 Fair Value of the Common Warrants

 The Common Warrants had a fair value of $ 5.0 million (liability) upon issuance in January 2024, and were subsequently measured at fair value using Level 3 inputs. The estimated fair value of the Common Warrant liability as of December 31, 2024 was $ 4.6 million. An adjustment of $( 0.4) million to the fair value of the Common Warrants was recorded in (loss) gain on fair value adjustment on the consolidated statements of operations and comprehensive loss for the year ended December 31, 2024.

 The following table summarizes the significant inputs used to estimate the fair value of the Common Warrant liability as of December 31, 2024 and January 23, 2024:

 Treasury Stock

 In 2018, in connection with the 2.50 % Notes, the Company entered into a prepaid forward stock repurchase transaction ("Prepaid Forward") with a financial institution ("Forward Counterparty"). Pursuant to the Prepaid Forward, the Company used approximately $ 45.1 million of the net proceeds from its issuance of the 2.50 % Notes to fund the Prepaid Forward. The aggregate number of shares of the Company's common stock underlying the Prepaid Forward was approximately 185,850. During March 2023, 185,850 shares of common stock were returned to the Company pursuant to its agreement with the Forward Counterparty. As of December 31, 2024 and 2023, these shares purchased under the Prepaid Forward were treated as treasury stock on the consolidated balance sheets (and not outstanding for purposes of the calculation of basic and diluted earnings per share).

 NOTE 19. SUBSEQUENT EVENTS

 Nasdaq Delisting Notice

 On January 28, 2025, the Company received written notice from Nasdaq's Listing Qualifications Staff (the "Staff") notifying the Company that for the last 31 consecutive business days, the Market Value of Listed Securities was below the minimum of $35 million required for continued listing on The Nasdaq Capital Market ("MVLS Requirement"). In accordance with Nasdaq rules, the Company has been provided with an initial period of 180 calendar days, or until July 28, 2025, to regain compliance with the MVLS Requirement. If, at any time before this date, the market value of the Company's common stock closes at $35 million or more for a minimum of ten consecutive business days, Nasdaq will provide written confirmation to the Company and close the matter. If the Company does not regain compliance with the MVLS Requirement prior to this date, Nasdaq will provide written notification that the Company's common stock will be subject to delisting. At that time, the Company may appeal the Staff's delisting determination to a Nasdaq Hearing Panel. The Company is evaluating potential actions to regain compliance with the MVLS Requirement and intends to actively monitor the market value of common stock. The Company may also, if appropriate, consider other options to regain compliance with Nasdaq's continued listing standards.

 Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

 Item 9A. Controls and Procedures

 Management's Evaluation of Disclosure Controls and Procedures

 The Company's management, under the supervision and with the participation of its Principal Executive Officer and Principal Financial Officer, evaluated the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of December 31, 2024. Based on the evaluation, the Company's Principal Executive Officer and Principal Financial Officer have concluded that the Company's disclosure controls and procedures were effective as of December 31, 2024, to ensure that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and (ii) accumulated and communicated to the Company's management, including its Principal Executive Officer and Principal Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

 Management's Report on Internal Control over Financial Reporting

 The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. GAAP. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance

 with respect to financial statement preparation and presentation. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. The Company's management, including its Principal Executive Officer and Principal Financial Officer, conducted an evaluation of the effectiveness of the Company's internal control over financial reporting based on the framework in Internal Control-Integrated Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, the Company's management concluded that our internal control over financial reporting was effective as of December 31, 2024.

 This Form 10-K does not include an attestation report of the Company's independent registered public accounting firm because, as a "smaller reporting company" and non-accelerated filer, the Company's independent registered public accounting firm is not required to issue such an attestation report.

 Changes in Internal Control Over Financial Reporting

 There were no changes in the Company's internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) under the Exchange Act during the quarter ended December 31, 2024, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
