 Item 1. Business

 Overview

 Lifeloc Technologies, Inc., a Colorado corporation
("Lifeloc" or the "Company"), is a Colorado-based developer, manufacturer and marketer of portable hand-held
and fixed station breathalyzers and related accessories, supplies and education. We design, produce and sell fuel-cell based breath
alcohol testing equipment. We compete in all major segments of the portable breath alcohol testing instrument market, including
law enforcement, workplace, corrections, original equipment manufacturing ("OEM") and consumer markets. In addition, we offer
a line of supplies, accessories, services, and training to support customers' alcohol testing programs. We sell globally through distributors
as well as directly to users.

 We define our business as providing "near
and remote sensing and monitoring" products and solutions. Today, the majority of our revenues are derived from products and services
for alcohol detection and measurement. We remain committed to growing our breath alcohol testing business. In the future, we anticipate
the commercialization of new sensing and measurement products that may allow Lifeloc to successfully expand our business into new growth
areas where we do not presently compete or where no satisfactory product solutions exist today.

 In addition, with the October 2014 purchase
of our corporate headquarters and certain adjacent property, we added a new reporting segment focused on the ownership and rental of real
property through existing commercial leases.

 Lifeloc incorporated in Colorado in December 1983. We
filed a registration statement on Form 10 with the Securities and Exchange Commission, which became effective on May 31, 2011. Our
fiscal year end is December 31. Our principal executive offices are located at 12441 West 49th Avenue, Unit 4, Wheat Ridge, Colorado
80033-3338. Our telephone number is (303) 431-9500. Our websites are www.lifeloc.com and www.stsfirst.com. Information

 Principal Products and Services and Methods
of Distribution

 Alcohol Breath Testers

 In 1989, we introduced our first breath
alcohol tester, the PBA3000. Our Phoenix Classic was completed and released for sale in 1998, superseding the PBA3000. In turn,
the Phoenix Classic has been superseded by our FC Series and Workplace Series of portable breath alcohol testers, which are
discussed below. Neither the PBA3000 nor the Phoenix Classic is actively sold today.

 In 2001, we completed
and released for sale our new FC Series, designed specifically for domestic and international law enforcement and corrections markets.
The portable breath alcohol testers comprising our FC Series are currently being sold worldwide, having contributed to our growth since
their introduction. The FC Series is designed to meet the needs of domestic and international law enforcement for roadside drink/drive
testing and alcohol offender monitoring. The FC Series is approved by the U.S. Department of Transportation ("DOT") as an
evidential breath tester, making it suitable for sale to state law enforcement agencies for preliminary roadside breath alcohol testing. The
FC Series is routinely updated with firmware, software and component improvements as they become available. It is readily adaptable
to the specific requirements and regulations of domestic and international markets.

 In 2005 and 2006, we introduced two new models,
the EV30 and Phoenix 6.0 Evidential Breath Tester ("Phoenix 6.0"), which constitute our Workplace Series of testing
devices. Like their predecessor, the Phoenix Classic, and our FC Series, these instruments are DOT approved. The DOT's
specifications support the DOT's workplace alcohol testing programs, including those applicable to workplace alcohol testing for
the federally regulated transportation industry. We also sell component parts used in alcohol testing devices, such as mouthpieces used
by our breathalyzers, as well as forms and labels used for record keeping, and calibration products for user re-calibration of our devices. We
offer optional service agreements on our equipment, re-calibration services, and spare parts, and we sell supporting instrument training
and user certification training to our workplace customers.

 In 2006, we commenced selling breath alcohol
equipment components that we manufacture to other OEMs for inclusion as subassemblies or components in their breath alcohol testing devices.

 In late 2009, Lifeloc released the LifeGuard Personal
 Breathalyzer ("LifeGuard"), a personal alcohol breath tester that incorporates the same fuel-cell technology used in
 our professional devices. Intended originally for the global consumer breathalyzer market, LifeGuard was phased out in 2018.

 In 2011 and 2012, Lifeloc introduced Bluetooth
wireless keyboard and printer communication options for our Phoenix 6.0 along with a series of web based workplace training
courses. We believe these two product innovations have been key to our success and leadership in workplace breath testing.

 In 2013, Lifeloc expanded our FC Series of
professional breath alcohol testers targeted at domestic and international law enforcement and corrections markets with the addition of
the FC5 Hornet (the "FC5"). The FC5 is a passive (no mouthpieces required) portable handheld alcohol screening device that
competes directly with passive alcohol screeners from our competitors in the education, law enforcement, workplace and corrections markets.

 In 2013, we also introduced the Sentinel
zero tolerance alcohol screening station, a fully automated wall mounted screening station for use in safety sensitive industries such
as oil and gas and mining. Both devices expand Lifeloc's products for passive alcohol screening.

 In the third quarter of 2014, we received approval
from DOT for our EASYCAL automatic calibration station for use with our Phoenix 6.0 Evidential Breath Testers, and we began
shipments of the EASYCAL to our law enforcement, corrections, workplace and international customers. The EASYCAL
calibration station is a first of its kind device that automatically performs breath tester instrument calibration, calibration verification
and gas management. As compared to manual instrument calibration, the EASYCAL reduces the opportunity for human error, saves
time and reduces operating costs. In May 2019, we received DOT approval on a second generation EASYCAL with broader capabilities
called the EASYCAL G2.

 In October 2015, we expanded our Sentinel
line with the Sentinel VA alcohol screening station, a fully automated station to control vehicular access to safety critical facilities,
such as mines, refineries, power stations and nuclear facilities. The Sentinel VA alcohol screening station is intended to
allow all drivers entering a secure area to be tested quickly and efficiently without leaving their vehicle.

 In March 2017 we acquired substantially all
of the assets related to the Real-time Alcohol Detection and Reporting product ("R.A.D.A.R. ") from Track Group, Inc.
("TRCK") for $860,000 in cash. The purchased assets included the R.A.D.A.R. device with cellular reporting for
real-time alcohol monitoring, database infrastructure to tabulate and manage subscriber behavior, and biometric methodology and intellectual
property to fully automate identity verification. The R.A.D.A.R. device was designed to be part of an offender supervision
program as an alternative to incarceration, and it is assigned to offenders as a condition of parole or probation with random testing
throughout the day to demonstrate that they are meeting the conditions of their sentence. We purchased the assets of R.A.D.A.R. 100 in
2017, knowing the product needed significant upgrading, which was essentially completed and released for sale several years later as R.A.D.A.R.
200. This product met with little market acceptance as a result of the underperformance of one feature, namely, the biometric identification
confirmation. In order to meet certain SpinDx milepost commitments, and to optimally allocate resources, we withdrew R.A.D.A.R.
200 from the market in 2022. We have outsourced the development of R.A.D.A.R. 300 to a third party but which is currently on hold as a
result of focusing all of our effort on SpinDx.

 In November 2019, we received approval from
DOT for our LX9 and LT7 base unit alcohol breathalyzers. Both have been updated and both updated versions received DOT approval in December
2021.

 Testers for Drugs of Abuse

 SpinDx

 In August
2016 we entered into a patent license agreement with Sandia Corporation pursuant to which we acquired
the exclusive rights to develop, manufacture and market Sandia's patented SpinDx technology for the detection of drugs
of abuse. We believe this license agreement represents the beginning of a relationship that will become material to the Company in the
near future. A prototype was built by Sandia under our Cooperative Research and Development Agreement, and received in 2018, after which
we commenced work on commercializing the device. This effort was hampered by the pandemic, but with the recovery, our full attention has
been given to SpinDx. Although the patents to the base technology belong to Sandia, any improvements we make that are patentable
belong solely to Lifeloc. The first Lifeloc owned utility patent application was filed in February 2024.

 At the beginning of the computer age, data
was gathered and then sent to an outside service center for processing. Later, with the evolution
of the personal computer, data was gathered and processed locally. We believe SpinDx will drive the same evolution in drug testing.
Under current practice, a sample is collected and sent to an outside lab for analysis, with the results available a day later, sometimes several days later — at a usual cost of upwards of $100 -
 $300 per test. SpinDx makes it possible to collect a sample and get the results locally within minutes —
 at a cost expected to be in the range of $25 per test. There are efforts underway by others
to capture this market. However, SpinDx is unique in its ability to accurately and quickly process the sample and provide a quantitative
result vs. the very few devices available today. Lifeloc's excellent standing in its alcohol breathalyzer market is expected to
provide an edge so far as credibility of the new SpinDx drug detection product is concerned. Work will soon begin on teaming SpinDx
with Lifeloc's alcohol breathalyzer, which is expected to result in a marijuana breathalyzer.

 We are optimistic about the results of the
work to date and expect market introduction via beta testing beginning in 2025, with a sales-ready device in the first half of 2026. SpinDx uses a centrifugal disk with micro fluidic flow paths allowing
multiple tests to be carried out on a single small sample. The SpinDx platform has the potential to revolutionize real-time screening
for a panel of high abuse drugs, with the ability to quickly and quantitatively measure very low concentrations of drugs such as
 cocaine, heroin, methamphetamine, fentanyl, marijuana and others. We intend to use this technology, sometimes referred to as "Lab
on a Disk", to develop devices and tests that could be used at roadside, emergency rooms and
in workplace testing to get a rapid and quantitative measure for a panel of such drugs of abuse.

 Marijuana has many cannabinoids, including
delta-9-THC, which is the primary component that is psychoactive, i.e., the one that causes impairment. Cannabinoids are chemicals
found in cannabis that affect the brain and body by interacting with cannabinoid receptors, and can impact mood, memory, appetite,
pain, and more. After smoking or eating marijuana, the delta-9-THC enters the bloodstream causing the high – and the
impairment. Over the course of the next few hours, the liver metabolizes the delta-9-THC, converting it into other molecules that
are not psychoactive. We have detected delta-9-THC (the primary psychoactive component of marijuana) down to concentrations of 5
nanograms per milliliter in our laboratory. This includes resolving the psychoactive delta-9-THC from its inactive metabolites.

 Testing for the presence of delta-9-THC
requires the ability to isolate delta-9-THC from these other molecules. Competitive devices such as Drager's Drugtest 5000 and the
Sotoxa device are unable to make this separation, whereas SpinDx can do so by locking up the metabolites and then analyzing only
the remaining delta-9-THC. This capability is a patented feature of the technology we licensed from Sandia, but which has been improved
upon by Lifeloc and a patent application has been filed. The practical result of this important difference is that SpinDx delivers test
results that correlate more accurately to the level of psychoactive delta-9-THC than the competitive devices. Testing for the presence
of marijuana within, say an hour after smoking or eating, will produce the same positive result no matter which device is used. As a result
of the metabolizing process by the liver, however, starting after about an hour and continuing thereafter, the two competitive devices
will still show positive results - but due to the proprietary locking feature, SpinDx will not unless delta-9-THC is actually present.
And if it is actually present, SpinDx will read and show the level of impairing delta-9-THC. Once this difference becomes more widely
known, Lifeloc believes society will begin to develop a consensus as to what level is unacceptable for driving (similar, for example,
to.05 for alcohol).

 We expect the initial release of the new
product will consist of the SpinDx base reader unit, an oral fluid collection device and an analysis disk. We expect subsequent
product releases will utilize the same SpinDx base reader and collection devices for samples from blood and from breath. We completed
the upgrade of our base breathalyzer platform in 2019 (the LX9), and we remain committed to combining it with the SpinDx technology.
If successful, this combination will result in a marijuana breathalyzer.

 We intend to expand our drug detection offerings based
on the SpinDx technology platform. Following the initial release of the saliva test system, we expect to release a system based
on samples collected from blood and breath. The breath sample collection will be accomplished with a collection device coupled with
our LX9 breathalyzer. After collection, the blood and breath samples will be analyzed on the SpinDx reader with a disk designed
for the specific sample source be it saliva, blood or breath.

 Training

 Drug and alcohol testing is highly regulated;
thus quality training is an important component of our business. Initially, our network of Master Trainers provided classroom training
which generated certification fees. This was expanded to include instructor materials, online training modules and direct (live)
training via webcam. In 2011, we launched Lifeloc University, a Learning Management System (LMS), defined as "a software application
for the administration, documentation, tracking, reporting and delivery of educational courses or training programs." Lifeloc University
is a critical component for online training courses since it provides student accountability. The Lifeloc University LMS was updated
in 2018 to provide responsive design so it could be viewed on mobile devices and was updated in 2021 to reflect DOT rule and other changes.

 In December 2014, we acquired substantially
all of the assets of Superior Training Solutions, Inc. ("STS"), a company that develops and sells online drug and alcohol
training and refresher courses. We have augmented and updated the assets we acquired from STS to enable mobile device usage. These assets
complement our existing drug and alcohol training courses.

 Real Property

 On October 31, 2014, we purchased the commercial
property we use as our corporate headquarters and certain adjacent property in Wheat Ridge, Colorado. The building consists of 22,325
square feet, of which 19,551 square feet are occupied by us and 2,774 square feet are currently leased to one tenant whose lease expires
June 30, 2025. We intend to continue to lease the space we are not occupying, but in the future may elect to expand our own operations
into space currently leased to the other tenant. Our purchase of the property was partially financed through a term loan in an original
principal amount of $1,581,106, secured by a first-priority mortgage on the property. This loan was paid on September 30, 2021 with proceeds
from a new term loan, also secured by a first-priority mortgage on the property, in the principal amount of $1,350,000 which matures in
September 2031.

 Additional Areas of Interest

 Consistent with our business goal of providing "near
and remote sensing and monitoring" products and solutions, our acquisition strategy involves purchasing companies, development resources
and assets that are aligned with our areas of interest and that can further aid in our entry into additional markets. We expect
to actively research and engage in the acquisition of resources that can expedite our entrance into new markets or strengthen our position
in existing ones.

 Competition and Markets

 We sell our products in a highly competitive market
and we compete for business with both foreign and domestic manufacturers. Most of our competitors are larger and have substantially
greater resources than we do. In addition, there is an ongoing risk that other domestic or foreign companies who do not currently
service or manufacture products for our target markets may seek to produce products or services that compete directly with ours.

 We believe that considerations regarding competition
for sales of alcohol monitoring products and services include regulatory approvals, product performance, product delivery, quality, service,
training, price, device reliability, ease of use and speed. We sell certain of our components to customers for incorporation
into their own product lines and for resale under their own name. We believe that, while our resources are more limited than
those of our competitors, we will continue to compete successfully on the basis of product innovation, quality, reputation and continued
customer service excellence.

 One of our leading competitors is Intoximeters, Inc.
of St. Louis, Missouri, a long-established company with strong name recognition in the field of alcohol testing. It has well-established
sales channels, a large customer base, and a broad product line. CMI, Inc. of Owensboro, Kentucky, another major competitor,
also has a well-established name, a strong position in stationary units used in police work, and international market coverage. Dr gerwerk
AG & Co. KGaA, based in Germany, manufactures safety and gas testing equipment. Its breath alcohol testers are respected
for their quality and performance.

 Our competition in the development of a marijuana
breathalyzer includes Cannabix Technologies, Inc., a developer of marijuana and alcohol breathalyzer technologies for law enforcement,
workplaces and laboratories that is working on developing delta-9 THC and alcohol screening devices, and Hound Labs, which is also developing
a marijuana breathalyzer. Both competitors in this space have raised significant funds to develop their testing technology.

 In addition, other technologies for the measurement
of breath alcohol exist and are employed in other market and application segments where the technology may be more suitable or developed
to specific requirements. These include:

 •

 Infrared devices, which use infrared light absorption to detect breath alcohol. These devices generally lack portability, and are usually found in fixed locations, such as police stations, where subjects are brought for testing. This technology has the advantage of being mandated by law in most states for evidential use in breath testing.

 •

 Semiconductor breath testing technology, which is used primarily in consumer breathalyzers. Its primary advantage is low cost, but the technology is not widely accepted by professional users as being as accurate as fuel cell technology.

 •

 Chemical tests, which are based on urine and saliva testing. This approach to alcohol testing is more invasive, less convenient than breath testing, and may require subsequent analysis for results.

 •

 Blood alcohol tests, which require blood samples. These tests are widely believed to be the most accurate form of alcohol testing because they measure blood alcohol content directly from a sample of the subject's blood. However, the results are not instantaneous, and the tests are more invasive and expensive than breath alcohol testing.

 Marketing

 Marketing activities associated with our business
include the communication of our value proposition through direct mail, direct and indirect sales channels, trade shows and an information-rich
online presence. We sell our products to the workplace and international markets primarily through distributors. We
sell our law enforcement, corrections and consumer products directly to the end user and our OEM products directly to manufacturers. Leveraging
our installed base is important, as is maintaining a well-trained distributor network. In 2009, we revised our workplace distributor
program to place additional emphasis on volume incentives for growth in the form of a rebate program. Under the program, qualifying
distributors receive a progressively greater percentage rebate based on the dollar sales they generate. We believe this program helps
incentivize our distributors to achieve a higher level of sales than would otherwise be the case.

 Domestic Distribution

 The majority of our sales into the workplace market
are made through distributors. Sales are made by these distributors pursuant to agreements that renew automatically each year
unless terminated by either party with advance notice, and such agreements typically grant protected lead generation areas.

 International Distribution

 Over 90% of our international
sales for all product lines are made by local distributors, who are given territories generally pursuant to agreements that renew automatically
each year unless terminated by either party with advance notice. Based on reports from our international distributors, we
believe that many countries around the world are instituting tougher alcohol abuse prevention laws, strengthening the enforcement of
current laws, or both. These laws set limits on the amount of alcohol an individual may have in the blood at specific times (e.g., while
driving or during safety-sensitive work activities), or at any time for certain parolees and probationers. Lifeloc has sold
instruments to customers in over 65 countries on six continents worldwide.

 Research, Development and Sustaining Engineering

 Lifeloc defines its business broadly to include "near
and remote sensing and monitoring" applications in markets including those outside of traditional alcohol testing. We believe
that our future success depends to a large degree on our ability to conceive and develop improved alcohol detection and measurement products,
as well as to identify attractive opportunities for growth outside of breath alcohol testing. Accordingly, we expect to continue
to invest in research, development and sustaining engineering. We spent $2,242,869 and $1,835,164 during 2024 and 2023, respectively,
on research and development, and on sustaining engineering. The amount spent in 2024 was $407,705 higher than the amount spent in 2023
due primarily to dedicating resources to commercializing SpinDx. We expect to continue to increase our emphasis on new product development
efforts for existing and new markets with particular emphasis on developing the SpinDx technology. Sustaining engineering is required
to maintain and continuously update our base products.

 Raw Materials and Principal Suppliers

 A basic component of our instrument product line is
the fuel cell, which we obtain from only a few suppliers. We believe that our demand for this component is small relative to the
total supply, and that the materials and services required for the production of our products are currently available in sufficient quantities
and will be available for the foreseeable future. However, there are relatively few suppliers of the high-quality fuel cells which
our breathalyzers require. Any sudden disruption to the supply of our fuel cells would pose a significant risk to our business.
New sources of fuel cells are uncertain at this time and changes to our fuel cells require approval by the DOT, which, if not received,
could have a material effect on our revenues. While we have traditionally used only one supplier of fuel cells, we completed development
of our own fuel cell assembly capability, using purchased sensors, in 2018. These Lifeloc-assembled fuel cells have been incorporated
into breathalyzers which have been submitted to and approved by the DOT. Even with the approval of our own assembled fuel cells, we continue
to purchase a portion of our total fuel cell requirements from our current supplier as necessary to meet the needs of the Company.

 Supply chain disruptions experienced in 2023 forced
us to maintain larger inventories of certain items in order to accommodate longer lead times, particularly components sourced internationally.
This policy was continued in 2024.

 Patents, Intellectual Property and Royalties

 We rely, in part, upon patents, trade secrets and
proprietary knowledge as well as personnel policies and employee confidentiality agreements concerning inventions and other creative efforts
(collectively, "Lifeloc IP") to develop and to maintain our competitive position. We do not believe that our business is dependent
upon any patent, patent pending or license, although we believe that trade secrets and confidential know-how may be important to our commercial
success.

 We file for patents, copyrights and trademarks to
protect our intellectual property rights to the extent practicable. We hold the rights to four United States patents and have two United
States patent applications pending or in preparation for filing, along with international patent applications on our portable breath alcohol
testers. These patents have expiration dates ranging from January 2027 to February 2042. In 2017, we acquired seven United States
patents and several active international patent applications in connection with our purchase of the R.A.D.A.R. assets. The R.A.D.A.R.
patents and patent applications provide protection around the biometric identification methods used in the R.A.D.A.R. devices along
with a removable sampling chamber for maximum hygienics.

 We act to protect our patents from infringement in
each instance where we determine that doing so would be economical in light of the expense involved and the level and availability of
our financial resources. While we believe that each of our pending applications relate to a patentable device or concept, there
is no guarantee that the patents will be issued.

 We also enter into royalty and licensing agreements
 where we license or otherwise confer our intellectual property rights on a licensor in exchange for specified payment terms. In 2012 we
 entered into a royalty agreement with an OEM customer which provides for the monthly payment of royalties to us on all products containing
 certain of our software sold by our customer. The agreement is of perpetual duration, but is terminable by the OEM customer upon
 six months' notice. In 2013 we began receiving royalties from another customer as a result of entering into a second royalty agreement,
 which provides for the monthly payment of royalties to us on all products containing certain of our software sold by our customer. The
 agreement is of perpetual duration, but is terminable by the customer upon six months' notice or by us upon 12 months' notice.

 Employees

 As of December 31, 2024, we had 39 full-time employees
and 2 part-time employees. We are not a party to any collective bargaining agreements.

 Environmental Matters

 Our operations are subject to a variety of federal,
state and local laws and regulations relating to the discharge of materials into the environment or otherwise related to the protection
of the environment. Lifeloc sells cylinders of ethanol in nitrogen (UN1956, Class 2.2) for use in calibrating breath alcohol
testers. The gas mixture is a hazardous material as defined by the DOT (see 49 CFR 172). We believe we are in substantial compliance with
the appropriate DOT regulations for the handling and shipment of dry gas containers, as well as all other state or local laws governing
the transportation of hazardous materials. The DOT regulations include strict labeling and packaging requirements, as well as requirements
pertaining to shipping papers and declaration forms that must be completed by the shipper. In addition, we provide a Safety
Data Sheet ("SDS") with every tank, and all employees involved in shipping hazardous materials are required to have appropriate
certification. Failure to comply with these regulations could result in, among other things, revocation of required licenses,
administrative enforcement actions, fines and civil and criminal liability, which could have a material impact on our business. The cost
of complying with these regulations is considered as an ongoing cost of operations, and is not material.

 Government Regulation of the Business

 In connection with its distribution of cylinders
of ethanol in nitrogen for use in calibrating breath alcohol testers (described above under "—Environmental Matters"),
Lifeloc has trained on and is following the requirements of OSHA's Hazardous Communications Standard of 2012 (referred to as "HazCom
2012"). Compliance with HazCom 2012 requires providing employee information and training, labeling of chemicals used by Lifeloc and
updating MSDS to the new harmonized Safety Data Sheets ("SDS") as they become available. It also requires us to prepare and
implement a hazard communication program to follow for workers potentially exposed to hazardous chemicals.

 We are also subject to regulation by the United
States Department of Transportation ("DOT") and by various state departments of transportation. The Omnibus Transportation
Employee Testing Act of 1991 requires drug and alcohol testing of safety-sensitive transportation employees in aviation, trucking, railroads,
mass transit, pipelines, and other transportation industries. The DOT Office of Drug & Alcohol Policy & Compliance ("ODAPC")
publishes, implements, and provides authoritative interpretations of these rules. These regulations cover all transportation employers,
safety-sensitive transportation employees, and service agents. Manufacturers submit devices to the DOT for testing and approval.
Instruments are tested according to their model specifications and, if passed, included on the Conforming Products List of Evidential
Breath Alcohol Measurement Devices (the "CPL") published periodically in the Federal Register. Law enforcement applications
also require that portable breath testing instruments be included on the CPL. Lifeloc's FC10, FC10Plus, FC20, FC20BT, EV30, and
Phoenix 6.0 and Phoenix 6.0BT are included on the CPL. Lifeloc's LX9 and LT7 have received conformance letters from the
DOT and are expected to appear in the next publication of the CPL.

 We believe that we were in substantial compliance
with the regulations described above as of December 31, 2024 for our products sold into these markets and states.

 See
also Item 1A. Risk Factors – "We are subject to a high degree of regulatory oversight and, if we do not continue to receive
the necessary regulatory approvals, our revenues may decline."

 International
Regulations

 Outside of the United States, Lifeloc is subject to
applicable regional and foreign regulations. In order to sell our products in the European Union, a CE mark is required, which declares
product conformity to relevant directives. Product directives include electromagnetic compatibility and environmental directives which
restrict the use of certain hazardous substances in electronic equipment. Lifeloc has a number of CE marked products and we follow
other foreign regulations as they apply.

 Many countries into which our products are sold recognize
the CPL in their selection criteria or have no regulations applicable to the sale of our products. In the case of sales into countries
that do not recognize the CPL in their selection criteria, our products conform to in-country developed specifications or are not subject
to significant government regulation.

 State and Local Regulations

 In certain states, the results of portable fuel-cell
breath testers are admissible as evidence of intoxication in DUI prosecution. In other states, infra-red technology is considered the
standard for evidence of intoxication, because of its ability to perform real-time analysis of the entire breath exhalation thereby giving
it the ability to detect interference from mouth alcohol. In those states, portable fuel-cell based breath testers are not admissible
as evidence of intoxication, although they may still be used to establish "probable cause."

 Insurance

 We are covered under comprehensive general liability
insurance policies, which have per occurrence and aggregate limits of $1 million and $2 million, respectively, and a $5 million umbrella
policy. We maintain customary property and casualty, workers' compensation, employer liability and other commercial insurance
policies.

 Human Capital Resources

 At Lifeloc Technologies, we promise to expand human
 possibility within our company and we work to attract and develop highly engaged people who can and want to do their best work. A culture
 of integrity is fundamental to Lifeloc's core values, including a code of ethics. That applies to our principal executive officer,
 principal financial officer, principal accounting officer and all other directors and management personnel. This code of ethics prohibits
 corrupt acts, bribery and anticompetitive behavior. Employee training is used to reinforce our values companywide, with participation
 in trainings related to ethics, environment, health and safety responses at or near 100%. We make the safety and health of our employees
 a top priority. We strive for zero workplace injuries and illnesses and operate in a manner that recognizes safety as fundamental to Lifeloc
 being a great place to work. We invest in growth and development of our employees. We take pride in our culture and make every effort
 to promote from within. We offer workplace benefits to all full-time employees. Our comprehensive benefits include healthcare benefits,
 disability and life insurance benefits, paid time off, and leave programs. Lifeloc offers plans and resources to help employees meet future
 savings goals through retirement savings plans. We offer flextime, remote work, and part-time arrangements whenever business conditions
 permit. Productivity and continuous improvement are important components of our workplace culture.

 Item 1A. Risk Factors

 You should carefully consider the risk factors described
below. If any of the following risk factors actually occur, our business, prospects, financial condition or results of operations would
likely suffer. In such case, the trading price of our common stock could fall, resulting in the loss of all or part of your investment.
You should look at all these risk factors in total. Some risk factors may stand on their own. Some risk factors may affect (or be affected
by) other risk factors. You should not assume we have identified these connections. You should not assume that we will always update these
and future risk factors in a timely manner. Except as required under applicable securities laws, we are not undertaking any obligation
to update these risk factors to reflect events or circumstances after the date of this report or to reflect the occurrence of unanticipated
events.

 Risks Related to Our Business and Industry

 There is no assurance that our efforts to develop
a marijuana breathalyzer will be successful or that significant sales will result from such development if successful.

 We are currently investing significant resources in
the development of our SpinDx product line, in an effort to be the first viable product to address the potential market opportunity for
testers for drugs of abuse. Though we have made significant progress toward commercialization of our first product in this space, there
is no assurance that our efforts will ultimately succeed or, if they do, that we will be able to capture a significant amount of market
share.

 Global economic conditions could have a negative
impact on our business, operating results and financial condition.

 Our business can be positively or negatively affected
by fluctuations in exchange rates and country by country economic conditions. Our international customers increase, reduce, delay
or cancel their purchases of our products when exchange rates are unfavorable to importation. Unfavorable economic and currency
situations at times force us to adjust prices downward to remain competitive. We incur losses if a customer's business fails and the customer
is unable to pay us, or pay us on a timely basis. Likewise, if our suppliers have difficulty in obtaining credit or in operating their
businesses, they may not be able to provide us with the materials we use to manufacture our products. Our law enforcement business
is dependent on the availability of federal and state grants to fund new equipment purchases. Should this funding be unavailable or delayed,
our volume may be negatively affected. Our workplace business may be affected by the health of industries with safety-sensitive jobs such
as oil and gas and transportation. Demand for our products may be affected by downturns in these segments. These actions would result
in reduced revenues and higher operating costs, and have an adverse effect on our results of operations and financial condition.

 Potential shifts in U.S. trade policy may impact
our business operations and supply chain.

 With the recent U.S. presidential election and transition
in executive branch leadership, the incoming administration has announced plans to impose new tariffs, including a 10% tariff on Chinese
imports and 25% tariffs on imports from Mexico and Canada. If implemented, these tariffs could increase the costs of imported goods and
components, affecting our cost structure, pricing strategy, and profitability. Furthermore, an increase in countervailing duty and anti-dumping
investigations could result in additional trade restrictions or higher duties on key materials, further impacting our operations. Retaliatory
tariffs from affected countries could also disrupt our supply chain and reduce demand for U.S.-based exports, potentially affecting our
international revenue streams.

 We rely on foreign-manufactured components and global
supply chains, and any increase in tariffs or trade restrictions may force us to seek alternative suppliers, renegotiate pricing, or absorb
higher costs, which could have a material adverse effect on our financial condition and results of operations. As the political landscape
evolves, we may need to adjust our strategies to comply with new regulatory and trade policies, which could result in increased costs,
operational disruptions, or limitations on our ability to conduct business internationally.

 Geopolitical instability and international conflicts
may disrupt our operations, supply chain, and financial performance.

 Ongoing and escalating international conflicts, including
the Ukraine-Russia war and multiple conflicts in the Middle East, continue to create economic and geopolitical uncertainty, which may
adversely impact our business. Trade restrictions, sanctions, and supply chain disruptions resulting from these conflicts could materially
affect our cost structure, operational efficiency, and overall financial performance.

 Beyond regulatory concerns, ongoing conflicts may
also create significant supply chain inefficiencies by increasing transportation costs, delaying shipments, and restricting the availability
of critical materials. We cannot predict the duration or outcome of these geopolitical tensions, nor the extent to which future sanctions
or conflicts may escalate. However, we remain subject to potential financial and operational risks associated with global instability.
If our international operations, suppliers, or markets are affected by sanctions, military actions, trade barriers, or regulatory changes,
our business, results of operations, and financial condition could suffer.

 We rely on customers who may not consistently
purchase our products in the future and if we lose any one of these customers, our revenues may decline.

 Sixteen percent of our product sales in 2024 and fifteen
percent in 2023 were attributable to three customers, with whom we do not have long-term contracts. If orders from those customers
are not renewed, our revenues may be adversely affected. Furthermore, at December 31, 2024, our accounts receivable balance
included approximately $339,925 or 46% from one customer, $27,383 or 4% from a second customer, and $19,684, or 3%, from a third customer.

 In the future, a small number of customers may continue
to represent a significant portion of our total revenues in any given period. These customers may not consistently purchase our products
at a particular rate over any subsequent period. A loss of any of these customers could adversely affect our revenues.

 We rely heavily upon the talents of our Chief
Executive Officer, the loss of whom could severely damage our business.

 Our performance depends to a large extent on a small
number of key managerial personnel. In particular, we believe our success is highly dependent upon the services and reputation of our
Chief Executive Officer and President, Dr. Wayne R. Willkomm. Loss of Dr. Willkomm's services could severely damage our business.

 We must continue to be able to attract employees,
including employees with the scientific and technical skills that our business requires, and if we are unable to attract and retain such
individuals, our business could be severely damaged. Labor shortages across the country threaten to damage our business.

 Our ability to attract employees, including employees
 with a high degree of scientific and technical talent is crucial to the success of our business. There is intense competition for the
 services of such persons, and we cannot guarantee that we will continue to be able to attract and retain individuals possessing the necessary
 qualifications. If we cannot attract such individuals, we may not be able to keep our products current, bring new innovations to
 market or produce our products. As a result, our business could be damaged. Additionally, labor shortages, which have become more common
 due to COVID-19 impacts, threaten to damage our business.

 Our
growth depends in part on the timely development and commercialization, and customer acceptance, of new and enhanced products and services.

 If we do not develop innovative new and enhanced products
and services on a timely basis, our offerings will become obsolete over time and our business will suffer. Our success depends on several
factors, including our ability to:

 •

 correctly identify customer needs and preferences and predict future needs and preferences;

 •

 allocate our R&D funding to products and services with higher growth prospects;

 •

 anticipate and respond to our competitors' development of new products and services and technological innovations;

 •

 differentiate our offerings from our competitors' offerings and avoid commoditization;

 •

 innovate and develop new technologies and applications;

 •

 obtain adequate intellectual property rights with respect to key technologies before our competitors do;

 •

 successfully commercialize new technologies in a timely manner, price them competitively and cost-effectively manufacture and deliver sufficient volumes of new products of appropriate quality on time;

 •

 obtain necessary regulatory approvals of appropriate scope; and

 •

 stimulate customer demand for and convince customers to adopt new technologies.

 If we fail to accurately predict future customer needs
and preferences or fail to produce viable technologies, we may invest heavily in R&D of products and services that do not lead to
significant revenue, which would adversely affect our business. Even when we successfully innovate and develop new and enhanced products
and services, we often incur substantial costs in doing so, and our profitability may suffer. In addition, promising new offerings may
fail to reach the market or realize only limited commercial success because of real or perceived efficacy or safety concerns.

 Our ongoing investment in new products,
services, and technologies is inherently risky, and could disrupt our ongoing businesses.

 We have invested and expect to continue to invest
in new products, services, and technologies. Such endeavors involve significant risks and uncertainties, including distraction of management
from current operations, insufficient revenues to offset liabilities assumed and expenses associated with these new investments, inadequate
return of capital on our investments, and unidentified issues not discovered in our due diligence of such strategies and offerings. Because
these new ventures are inherently risky, sometimes they have been unsuccessful and no assurance can be given that such strategies and
offerings will be successful and will not adversely affect our reputation, financial condition, and operating results.

 We are subject to a high degree of regulatory
oversight, and, if we do not continue to receive the necessary regulatory approvals, our revenues would decline.

 We are subject to regulation by the United States
 Department of Transportation ("DOT") and by various state departments of transportation. The Omnibus Transportation
 Employee Testing Act of 1991 requires drug and alcohol testing of safety-sensitive transportation employees in aviation, trucking, railroads,
 mass transit, pipelines, and other transportation industries. The DOT Office of Drug & Alcohol Policy & Compliance ("ODAPC")
 publishes, implements, and provides authoritative interpretations of these rules. These regulations cover all transportation
 employers, safety-sensitive transportation employees, and service agents. Manufacturers submit devices to the DOT for testing
 and approval. Instruments are tested according to their model specifications and, if passed, included on the CPL. Law
 enforcement applications also require that portable breath testing instruments be included on the CPL. Lifeloc's FC10, FC10Plus,
 FC20, FC20BT, EV30, and Phoenix 6.0 and Phoenix 6.0BT are included on the Conforming Products List of Evidential Breath Alcohol
 Measurement Devices ("CPL"). Lifeloc's LX9 and LT7 have received conformance letters from the DOT and are
 expected to appear in the next publication of the CPL. We believe that we were in substantial compliance with the regulations described
 above as of December 31, 2024 for our products sold into these markets and states.

 The DOT has approved the alcohol monitoring products we currently sell
in the United States. However, further DOT approval may be required before we can domestically market additional alcohol monitoring
products that we may develop in the future. We may also seek to sell new drug-related products, or market current products
for new uses, either of which could require us to obtain DOT approval to sell such products. We may also be required to obtain
regulatory approvals or licenses from other federal, state or local agencies or comparable agencies in other countries.

 We may not continue to receive DOT approval of our
current products or we may not obtain the necessary regulatory clearance, approvals or licenses for the marketing of any of our future
products. Also, we cannot predict the impact on our business of DOT regulations or determinations arising from future legislation
or administrative action. If we lose DOT permission to sell our current products or we do not obtain regulatory permission to sell
our future products, our revenues would likely decline, harming our business.

 Our business in the domestic law enforcement
area is susceptible to changes in state policies and DUI laws.

 Portable breath testers ("PBTs") are not
used to the same degree in each state. Usage is determined by a complex combination of individual state DUI laws, historical practice,
and individual state directions for alcohol testing. Some states do not accept breath alcohol testing as evidence. Other states may
prefer different breath alcohol testing technology, such as infrared. Lifeloc cannot control the direction or timing of changes to individual
state DUI laws, public and political sentiment toward the use of PBTs, or individual state preferences for a specific breath alcohol testing
technology. These factors threaten current state contracts and future state contracts and threaten revenue.

 Our business relies on state contracts, governed
by state contracting policies that are beyond our control.

 Many state purchases of PBTs are governed by state
contracts with competitive price bids, multiple year terms and without guarantees of purchases. Other states prefer to share PBT usage
across several vendors, also without guarantees of volume. These state practices limit Lifeloc's ability to retain current business, forecast
volumes and win new business.

 Furthermore, a significant amount of our law enforcement
business is concentrated in eight states (Arizona, Arkansas, California, Colorado, Michigan, Idaho, Texas and Nevada). Loss of this business,
or delays or cancellations in purchasing by these states, seriously impacts our law enforcement business.

 We derive a significant portion of our revenue directly
or indirectly from government customers, and our business may be adversely affected by changes in the contracting or fiscal policies of
those governmental entities.

 We derive a significant portion of our revenue directly or indirectly
from federal, international, state and local governments. We believe that the success and growth of our business will continue to depend
on government customers purchasing our products and services either directly from us or indirectly through our distributors. Changes in
government contracting policies or government budgetary constraints may adversely affect our financial performance. Among the factors
that could adversely affect our business are the impact of actions, such as those recently announced by the U.S. Department of Government
Efficiency, intended to reduce the size of the federal government and federal spending; other changes in fiscal policies or decreases
in available government funding; changes in government funding priorities; changes in government programs or applicable requirements;
the adoption of new laws or regulations or changes to existing laws or regulations relating to the provision of biometrics services or
the use of biometric data; changes in political or social attitudes with respect to security and defense issues; changes in audit policies
and procedures of government entities; potential delays or changes in the government appropriations process; and delays in the payment
of our invoices by government payment offices. These and other factors could cause government customers or our distributors to reduce
purchases of products and services from us, which would have a material adverse effect on our business, financial condition and operating
results.

 Third parties may infringe on our patents, and
as a result, we could incur significant expense in protecting our patents or not have sufficient resources to protect them.

 We hold several patents that are important to our
business. We plan to protect these patents from infringement and obtain additional patents whenever feasible. To this end, we have obtained
confidentiality agreements from our employees and consultants and others who have access to the design of our products and other proprietary
information. Protecting and obtaining patents, however, is both time consuming and expensive. We therefore may not have the
resources necessary to assert all potential patent infringement claims or pursue all patents that might be available to us. If
our competitors or other third parties infringe on our patents, our business may be harmed.

 Third parties may claim that we have
infringed on their patents and as a result, we could be prohibited from using all or part of any technology used in our products.

 Should third parties claim a proprietary right to
all or part of any technology that we use in our products, such a claim, regardless of its merit, could involve us in costly litigation. If
successful, such a claim could also result in us being unable to freely use the technology that was the subject of the claim, or sell
products embodying such technology. If we engage in litigation, our expenses may increase and our business may be harmed.
If we are prohibited from using a particular technology in our products, our revenues may decline and our business may be harmed.

 Third parties to whom we have licensed our patents
may choose to enforce them through litigation, over which we would exert little or no control.

 Should third parties who have licensed our intellectual
property determine it is in their best interest to pursue litigation based on those patents, we would have no control in the direction
of that litigation or the resulting publicity. Litigation may result in unfavorable findings by courts regarding the nature or protectability
of our intellectual property. Litigation may result in additional expenditures or harm the business. Additionally, we would have no control
over the publicity any such litigation may garner, which could negatively affect the company in the marketplace. In any of these situations,
revenues may decline and our business may be harmed.

 Failure of third parties from whom we license
key intellectual property to protect their intellectual property could adversely affect our business.

 We rely on third-party licensors for certain key intellectual
property that is important to our business, and we have limited control over how they protect and enforce their rights. If any of our
licensors fail to adequately protect, maintain, or enforce their intellectual property, it could result in unauthorized use, infringement
by third parties, or legal disputes that diminish the value of the licensed assets. Any such failure could negatively impact our ability
to use the intellectual property as intended, limit our competitive advantages, or expose us to potential litigation, which could materially
affect our business, financial condition, and results of operations.

 We
depend on the availability of certain key supplies and services that are available from only a few sources, and if we experience difficulty
with a supplier, we may have difficulty finding alternative sources of supply.

 We require certain key supplies for our products,
particularly fuel cells, that are available from only a few sources. Based upon our ordering experience to date, we believe
the materials and services required for the production of our products are currently available in sufficient quantities. However, this
does not mean that we will continue to have timely access to adequate supplies of essential materials and services in the future or that
supplies of these materials and services will be available on satisfactory terms when the need arises. Our business could be severely
damaged if we become unable to procure essential materials and services in adequate quantities and at acceptable prices.

 From time to time, subcontractors may produce certain
of our products for us, and our business is subject to the risk that these subcontractors may fail to make timely delivery and/or become
unable to acquire essential supplies and services from third parties in a timely fashion. If this occurs, we may not be able
to deliver our products on a timely basis and our revenues may decline. Our products and services are also from time to time used as components
in the products of other manufacturers. We are therefore subject to the risk that manufacturers that integrate our products or services
into their own products may change their source of supply to other vendors, may change their product designs in a way that eliminates
our components, and/or may choose to have their components manufactured by other means. If this occurs, our sales may decline
and our business may be harmed.

 We may be exposed to claims of liability.

 Like any manufacturer, we are and always have been
exposed to liability claims resulting from the use of our products. We maintain product liability insurance to cover us in
the event of liability claims, and as of December 31, 2024, no such claims have been asserted or threatened against us. However,
our insurance may not be sufficient to cover all possible future product liabilities.

 We could be liable if our business operations
harmed the environment, and a failure to maintain compliance with environmental laws could severely damage our business.

 Our operations are subject to a variety of federal,
state and local laws and regulations relating to the protection of the environment. From time to time, we use hazardous materials
in our operations. Although we believe that we are in material compliance with all applicable environmental laws and regulations,
our business could be severely damaged by any failure to maintain such compliance.

 Climate change may adversely impact
our business.

 The impact of continuing climate change could
result in increased costs or reduced demand for our products, carbon asset risks, risks due to severe weather events and may result in
the need for us to devote additional resources to the management of greenhouse gas emissions which will likely harm our profitability.

 Our quarterly financial results vary quarter
to quarter, which adversely affects our stock price at times. We cannot predict with any certainty our operating results in any particular
fiscal quarter.

 Our quarterly operating results may vary significantly
depending upon factors such as:

 •

 the timing of completion of significant orders;

 •

 the timing and amount of our research and development expenditures;

 •

 the costs of initial production in connection with new products;

 •

 the availability, quality and cost of key components that go into the assembly of our products;

 •

 the timing of new product introductions — both by us and by our competitors;

 •

 changes in the regulatory environment and regulations under which we operate;

 •

 the loss of a major customer;

 •

 the timing and level of market acceptance of new products or enhanced versions of our existing products;

 •

 our ability to retain existing employees, customers and our customers' continued demand for our products and services;

 •

 our customers' inventory levels, and levels of demand for our customers' products and services; and

 •

 competitive pricing pressures.

 We may not be able to grow or sustain revenues or
achieve or maintain profitability on a quarterly or annual basis, and levels of revenue and/or profitability may vary from one such period
to another.

 Identification of material weakness in internal control may adversely
affect our financial results.

 We are subject to the ongoing internal control provisions
of Section 404 of the Sarbanes-Oxley Act of 2002. Those provisions provide for the identification of material weaknesses in internal control.
If such a material weakness is identified, it could indicate a lack of adequate controls to generate accurate financial statements. We
routinely assess our internal controls, but we cannot assure you that we will be able to timely remediate any material weaknesses that
may be identified in future periods, or maintain all of the controls necessary for continued compliance.

 We may require additional capital in the future, which may not be
available or may only be available on unfavorable terms.

 We monitor our capital adequacy on an ongoing basis.
To the extent that our funds are insufficient to fund future operating requirements, we may need to raise additional funds through corporate
finance transactions or curtail our growth and reduce our liabilities. Any equity, hybrid or debt financing, if available at all, may
be on terms that are not favorable to us. If we cannot obtain adequate capital on favorable terms or at all, our business, financial condition
and operating results would be adversely affected.

 We have a number of large, well-financed competitors
who have research and marketing capabilities that are superior to ours.

 The industry in which we operate is highly competitive.
Many of our existing and potential competitors have greater financial resources and manufacturing capabilities, more established and larger
marketing and sales organizations and larger technical staffs than we have. Other companies, some with greater experience in
the alcohol monitoring industry, produce products and services that compete with our products and services. When our competitors
are successful in developing products that are superior to our products, or competing products that sell for lower prices, there is a
reduction in the demand for our products and a corresponding reduction in our revenue and our profits.

 Our products rely on technology that may become
outdated or out of favor.

 All of Lifeloc's products use fuel cell technology
for the measurement of breath alcohol results. This technology has been developed and refined over many years by Lifeloc and our major
competitors. While we expect it to remain as the dominant technology in breath testing devices, other technologies for the measurement
of breath alcohol exist and are employed in other market and application segments where the technology is more suitable or developed to
the specific requirements. Future development of these technologies pose a risk to Lifeloc's business. See "Item 1. Business –
Competition and Markets" for more information about these other technologies.

 Natural disasters, public health crises,
political crises, and other catastrophic events or other events outside of our control may damage our facilities or the facilities of
third parties on which we depend and could impact customer priorities and consumer spending.

 We have global third parties upon whom we
rely and who are sometimes impacted by events outside of our control. An earthquake or other natural disaster or power shortages or outages
could disrupt operations or impair sales. In addition, if any facilities of our suppliers, third-party service providers, vendors, or
customers, is affected by natural disasters, such as earthquakes, tsunamis, power shortages or outages, floods or monsoons, public health
crises, such as pandemics and epidemics, political crises, such as terrorism, war, political instability or other conflict, or other events
outside of our control, our business and operating results could suffer. Any of these disruptions or other events outside of our control
would affect our business negatively, harming our operating results.

 Increasingly common data privacy and cybersecurity regulations impact
the use of or market for our products.

 Information collected with our products may be governed
by certain data privacy and cyber security regulations, breach of which could cause negative publicity or otherwise harm the company.
As a Company with information stored online, the company may be vulnerable to cybersecurity attacks which may trigger reporting requirements
and legal liability. Responding to a cybersecurity threat or breach would require financial resources, would cause a loss of productivity,
and would open the Company to legal liability.

 Unstable market and economic conditions
may have serious adverse consequences on our business, financial condition and stock price.

 Global credit and financial markets have experienced
extreme volatility and disruptions in the past several years, including increased inflation, severely diminished liquidity and credit
availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic
stability, and the volatility of such market and economic conditions have increased as a result of the COVID-19 pandemic and the Russian
invasion of Ukraine. The scope, duration and long-term impact of the COVID-19 pandemic and the Russian invasion are unknown at this time,
so there can be no assurance how significant any deterioration in credit and financial markets and confidence in economic conditions will
be and how long it may continue. Our general business strategy may be adversely affected by any such economic downturn, volatile geopolitical
and business environment or continued unpredictable and unstable market conditions. If the current equity and credit markets deteriorate,
or do not improve, it may make any necessary debt or equity financing more difficult, more costly, and more dilutive. Failure to secure
any necessary financing in a timely manner and on favorable terms could have a material adverse effect on our growth strategy, financial
performance and stock price and could require us to delay or abandon research and development plans. In addition, there is a risk that
one or more of our current suppliers or other partners may not survive these difficult economic times, which could directly affect our
ability to attain our operating goals on schedule and on budget.

 U.S. Trade relations negatively impact the availability
of materials or the international market for the Company's product.

 Changes in U.S. trade relations, particularly the impositions of tariffs by the U.S. and China, have had and are expected to continue to have material effects on the performance of many companies. The Company is negatively affected by tariffs on any component materials required for a company product. Trade relations also decrease any potential international market for the Company products, affecting the Company's potential for growth.

 Risks Related to Our Stock

 Shares of our common stock lack a significant
trading market.

 Shares of our common stock are not eligible for trading
on any national securities exchange. Our common stock may be quoted in the over-the-counter market on the OTC Bulletin Board or in what
are commonly referred to as "pink sheets." However, these markets are highly illiquid. There is no assurance that an active
trading market in our common stock will develop, or if such a market develops, that it will be sustained. In addition, there is a greater
chance for market volatility for securities quoted on the OTC Bulletin Board and pink sheets as compared with securities traded on a national
exchange. This volatility may be caused by a variety of factors, including the lack of readily available quotations, the absence of consistent
administrative supervision of "bid" and "ask" quotations and generally lower trading volume.

 Under certain circumstances, shares of our common stock may be sold without
registration pursuant to the safe harbor provided in Exchange Act Rule 144 ("Rule 144"). Any sale under Rule 144 or under any
other exemption from the Securities Act of 1933, as amended (the "Securities Act"), if available, or pursuant to registration
of shares of common stock of present stockholders, may have a depressive effect upon the price of our common stock in any market that
may develop.

 Additionally, the price of our securities may be volatile
as a result of a number of factors, including, but not limited to, the following:

 •

 our ability to successfully conceive and to develop new products and services to enhance the performance characteristics and methods of manufacture of existing products;

 •

 our ability to retain existing customers and customers' continued demand for our products and services;

 •

 the timing of our research and development expenditures and of new product introductions;

 •

 the timing and level of acceptance of new products or enhanced versions of our existing products;

 •

 price and volume fluctuations in the stock market at large which do not relate to our operating performance; and

 •

 outside news reports which may or may not accurately convey information about us, our products, our prospects and opportunities.

 Our principal stockholder has significant voting
power and may take actions that may not be in the best interests of other stockholders.

 Vern D. Kornelsen, Chairman of our Board of Directors,
Secretary, and Chief Financial Officer, beneficially owned approximately 77% of our outstanding common stock as of December 31, 2024. Through
this ownership, Mr. Kornelsen is able to control the composition of our Board and direct our management and policies. Accordingly,
Mr. Kornelsen has the direct or indirect power to:

 •

 amend our bylaws and some provisions of our articles of incorporation; and

 •

 cause or prevent mergers, consolidations, sales of all or substantially all our assets or other extraordinary transactions.

 Mr. Kornelsen's significant ownership interest could adversely affect investors' perceptions of our corporate governance. In addition, Mr. Kornelsen may have an interest in pursuing acquisitions, divestitures and other transactions that involve risks to us and you. For example, Mr. Kornelsen could cause us to make acquisitions that increase our indebtedness or to sell revenue-generating assets. Mr. Kornelsen may from time to time acquire and hold interests in businesses that compete directly or indirectly with us.

 Stockholders should not anticipate receiving
cash dividends on our stock.

 We have never declared or paid any cash dividends
or distributions on our capital stock. We currently intend to retain future earnings to support operations and to finance expansion and
therefore do not anticipate paying any cash dividends on our common stock in the foreseeable future.

 We may issue shares in the future, diluting
your interest in us.

 We issue options to purchase shares of our common
stock to compensate employees, consultants and directors or to raise capital. Any such issuances will have the effect of further
diluting the interest of the holders of our securities.

 General Risk Factors

 Blue Sky considerations limit sales in certain
states.

 The holders of our securities and persons who desire
to purchase them in any trading market that might develop in the future should be aware that there may be significant state law restrictions
upon the ability of investors to resell our securities. Investors should consider any secondary market for our securities to be a limited
one. The "manual exemption" permits a security to be distributed in a particular state without being registered if the company
issuing the security has a listing for that security in a securities manual recognized by the state. However, it is not enough for the
security to be listed in a recognized manual. The listing entry must contain (1) the names of issuers, officers, and directors, (2) an
issuer's balance sheet, and (3) a profit and loss statement for either the fiscal year preceding the balance sheet or for the most recent
fiscal year of operations. Since June 14, 2011, we have been listed in Standard & Poor's. While many states expressly recognize this
manual, a smaller number of states declare that they "recognize securities manuals" but do not specify the recognized manuals,
making applicability of the manual exemption uncertain in those states. The following states do not have provisions expressly recognizing
the manual exemption: Alabama, Illinois, Kentucky, Louisiana, Montana, New York, Pennsylvania, Tennessee and Virginia. While we may, in
our discretion, cause our securities to be registered under the state securities laws of these or other states, there is no guarantee
that we will do so.

 Compliance with changing regulations of corporate
governance and public disclosure result in expense.

 We are subject to certain federal, state and other
rules and regulations, including those required by the Sarbanes-Oxley Act of 2002, new regulations promulgated by the SEC and the rules
of the OTC Market. The expense of compliance with these and other laws relating to corporate governance and public disclosure
is included in our general and administrative expenses. These laws, regulations and standards are subject to varying interpretations
in many cases, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing
bodies, which could result in higher costs necessitated by ongoing revisions to disclosure and governance practices. We are
committed to maintaining high standards of corporate governance and public disclosure. As a result, we invest resources to
comply with evolving laws, regulations and standards, and this investment results in increased general and administrative expenses and
a diversion of management time and attention from revenue-generating activities to compliance activities.

 Item 1B. Unresolved Staff Comments

 Not required for smaller reporting companies.

 Item 1C. Cybersecurity

 Cybersecurity Risk Management and Strategy

 We rely on third party providers and outsourced IT services to
monitor and address cybersecurity related risks, including installing software for threat protection and malware. Such third party providers
are tasked with notifying management of any material risks or cybersecurity concerns that they identify, which management then assesses
and may bring to our board of directors to discuss if deemed necessary or appropriate. Based on the results of our risk assessments, if
deemed necessary or appropriate, we take steps to re-design, implement, and maintain reasonable safeguards to minimize identified risks;
reasonably address any identified gaps in existing safeguards; and regularly monitor the effectiveness of our safeguards.

 We intend to work with outside counsel and third party service
providers to further develop our expertise, processes and procedures with respect to cybersecurity protection and our response plan.

 To date, we have not (to our knowledge) encountered cybersecurity
challenges that have materially affected our business strategy, results of operations, or financial condition.

 Cybersecurity Governance

 Our Audit Committee of our Board of Directors is tasked with general oversight
of our risk management process, including risks from cybersecurity threats. Members of management provide periodic briefings to the Audit
Committee of our Board of Directors regarding our cybersecurity risks and activities, including any recent cybersecurity incidents and
related responses, cybersecurity systems testing, activities of third parties, and the like. In furtherance thereof, the committee is
responsible for monitoring and assessing strategic risk exposure.

 Item 2. Properties

 On October 31, 2014, we purchased the commercial property
we use as our corporate headquarters and certain adjacent property in Wheat Ridge, Colorado. The building consists of 22,325 square feet,
of which 19,551 square feet are occupied by us and 2,774 square feet is currently leased to one tenant whose lease expires June 30, 2025
and does not have an option to renew. In addition to housing our corporate headquarters, we use this property for research and development,
manufacturing, shipping/receiving, warehouse, and inventory purposes. We may continue to lease the space we are not occupying, or we may
elect to expand our own operations into space currently leased to the other tenant. Our purchase of the property was partially financed
through a term loan in an original principal amount of $1,581,106, secured by a first-priority mortgage on the property. This loan was
paid on September 30, 2021 with proceeds from a new term loan, also secured by a first-priority mortgage on the property, in the principal
amount of $1,350,000 which matures in September 2031.

 Item 3. Legal Proceedings

 We may be involved from time to time in litigation,
negotiation and settlement matters that may have a material effect on our operations or finances. We are not aware of any material
pending legal proceedings, other than ordinary routine litigation incidental to our business, to which we are a party or of which any
of our property is subject.

 Item 4. Mine Safety Disclosures

 Not applicable.

 Item 5. Market for Registrant's Common Equity, Related
Stockholder Matters and Issuer Purchases of Equity Securities

 As of December 31, 2024, we had 65 shareholders of
record. Our common stock is not listed on an established public trading market. Since January 17, 2012, our stock has been quoted by the
OTC Markets Group, Inc., in the non-NASDAQ over the counter market. The symbol for our shares is LCTC. Trading in our common stock is
limited and sporadic. Subject to the foregoing qualification, the following table sets forth the range of bid quotations for the fiscal

 Dividend Policy

 We have never declared or paid any cash dividend on
shares of our common stock. We do not anticipate paying any cash dividends in the foreseeable future. We currently intend to retain future
earnings, if any, to finance our operations and expand our business. Any future determination to pay cash dividends will be at the discretion
of the board of directors and will be dependent upon our financial condition, operating results, capital requirements, and other factors
the board of directors deems relevant.

 Recent Sales of Unregistered Securities

 On July 23, 2024 we sold 210,000 shares of
common stock to EDCO Partners LLLP, an accredited investor of which our chairman is the managing partner, in a private placement pursuant
to Section 4(a)(2) and Regulation D of the Securities Act. The purchase price under the Private Placement was $3.80 per share, for a total
of $798,000 in proceeds to Lifeloc. There were no discounts or commissions paid to underwriters or placement agents. There were no sales
of equity securities during the year ended December 31, 2023.

 Item 6. [Reserved]

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

 The following is a discussion of our financial condition
and results of operations, and should be read in conjunction with our financial statements and the related notes included elsewhere in
this Form 10-K. Certain statements contained in this section are not historical facts, including statements about our strategies
and expectations about new and existing products, market demand, acceptance of new and existing products, technologies and opportunities,
market and industry segment growth, and return on investments in products and markets. These statements are forward-looking
statements and involve substantial risks and uncertainties that may cause actual results to differ materially from those indicated by
the forward-looking statements. All forward-looking statements in this section are based on information available to us on
the date of this document, and we assume no obligation to update such forward-looking statements. Readers of this Form 10-K
are strongly encouraged to review the section titled "Risk Factors."

 Overview

 Lifeloc Technologies, Inc., a Colorado corporation
("Lifeloc" or the "Company"), is a Colorado-based developer, manufacturer and marketer of portable hand-held
and fixed station breathalyzers and related accessories, supplies and education. We design, produce and sell fuel-cell based breath
alcohol testing equipment. We compete in all major segments of the portable breath alcohol testing instrument market, including
law enforcement, workplace, corrections, original equipment manufacturing ("OEM") and consumer markets. In addition, we offer
a line of supplies, accessories, services, and training to support customers' alcohol testing programs. We sell globally through distributors
as well as directly to users.

 We define our business as providing "near and
remote sensing and monitoring" products and solutions. Today, the majority of our revenues are derived from products and services
for alcohol detection and measurement. We remain committed to growing our breath alcohol testing business. In the future, we anticipate
the commercialization of new sensing and measurement products that may allow Lifeloc to successfully expand our business into new growth
areas where we do not presently compete or where no satisfactory product solutions exist today.

 In addition, with the October 2014 purchase of our
corporate headquarters and certain adjacent property, we added a new reporting segment focused on the ownership and rental of real property
through existing commercial leases.

 Lifeloc incorporated in Colorado in December 1983. We
filed a registration statement on Form 10 with the Securities and Exchange Commission, which became effective on May 31, 2011. Our
fiscal year end is December 31. Our principal executive offices are located at 12441 West 49th Avenue, Unit 4, Wheat Ridge, Colorado
80033-3338. Our telephone number is (303) 431-9500. Our websites are www.lifeloc.com and www.stsfirst.com. Information
contained on our websites does not constitute part of this Form 10-K.

 Outlook

 Installed Base of Breathalyzers. We
believe the installed base of our breathalyzers will increase as the inherent risks associated with drinking while driving or while working
in safety sensitive jobs become more widely acknowledged and as our network of distributors and our direct sales force grows. We
believe that increased marketing efforts, the introduction of new products and the expansion of our sales network may provide the basis
for increased sales and continuing profitable operations. However, these measures, or any others that we may adopt or determine
not to adopt, may not result in either increased sales or continuing profitable operations.

 Possibility of Operating Losses. Over
many of the past several years we have operated profitably; however, prior to that, and in 2021 through 2024, we incurred operating losses.
There is no assurance that we will not incur losses in any given quarter or year in the future.

 Sales Growth. We expect to increase
sales in the U.S. and worldwide as our network of direct customers and distributors grows and becomes more proficient and expands the
number of new accounts. Our growth efforts have focused on expanding our global reach and broadening our product offering in
alcohol and drug detection. Orders for all of our products, particularly ignition interlock components, are on an intermittent purchase
order basis and there is no assurance they will continue at any given rate, or that orders will repeat.

 Sales and Marketing Expenses. We
continue our efforts to expand our domestic and international distribution capability, and we believe that sales and marketing expenses
will need to be maintained at a healthy level in order to do so. Sales and marketing expenses are expected to increase as we
increase our direct sales representatives and marketing efforts.

 Research and Development Expenses. We
expect to increase our research and development expenses to support refinements to our products, and the development of additional new
products.

 SpinDx

 In August 2016 we entered into an exclusive patent
license agreement with Sandia Corporation pursuant to which we acquired the exclusive rights to develop, manufacture and market Sandia's
patented SpinDx technology for the detection of drugs of abuse. We believe this license agreement represents the beginning of a
relationship that will become material to the Company in the near future. A prototype was built by Sandia under our Cooperative Research
and Development Agreement and received in 2018, after which we commenced work on commercializing the device.

 In 2024 we purchased SpinDx related test and other
equipment totaling $667,738, compared with $0 spent in 2023. We are optimistic about the results of the work to date and expect market
introduction via extensive beta testing and validation through 2025 and commercialization in 2026. SpinDx uses a centrifugal disk
with micro fluidic flow paths allowing multiple tests to be carried out on a single small sample. The SpinDx platform has
the potential to revolutionize real-time screening for a panel of high abuse drugs, with the ability to quickly and quantitatively measure
very low concentrations of drugs such as cocaine, heroin, methamphetamine and others. We intend to use this technology, sometimes
referred to as "Lab on a Disk", to develop devices and tests that could be used at roadside, emergency rooms and in workplace
testing to get a rapid and quantitative measure for a panel of such drugs of abuse. We have detected delta-9-THC (the primary psychoactive
component of marijuana) down to concentrations of 5 nanograms per milliliter in our laboratory. This includes resolving the psychoactive
delta-9-THC from its inactive metabolites. Resolving the psychoactive levels from metabolites is an important step in establishing impairment.
We completed the upgrade of our base breathalyzer platform in 2019 (the LX9), and we remain committed to combining it with the SpinDx
technology. If successful, this combination will result in a marijuana breathalyzer.

 R.A.D.A.R.

 On March 8, 2017, we entered into an Asset
Purchase Agreement (the "Asset Purchase Agreement") with Track Group Inc., a Delaware corporation. Pursuant to the terms and
conditions of the Asset Purchase Agreement, we acquired certain assets comprised of: (1) handheld hardware device technology (the "R.A.D.A.R.
Mobile Devices"), designed to measure breath alcohol content of the user; and (2) software technology called R.A.D.A.R. (Real-time
Alcohol Detection and Reporting) Reporting Center designed to allow the Device to be configured and to capture and manage the data being
returned from the Device (together with the Device, the "R.A.D.A.R. Assets"). We purchased the assets of R.A.D.A.R. 100
knowing the product needed significant upgrading, which was essentially completed and released for sale in 2022 as R.A.D.A.R. 200. This
product met with little market acceptance as a result of the underperformance of one feature, generating nominal revenue in 2022 and none
in subsequent years. In 2023, we outsourced the development of R.A.D.A.R. 300 to a third party, but that effort is currently on hold as
a result of focusing all of our effort on SpinDx.

 Results of Operations

 For the year ended December 31, 2024 compared to the year ended December
31, 2023.

 Supply chain problems
caused by Covid-19, as well as the other market impacts of Covid-19, were mostly resolved by the end of 2024, and the perceived need to
monitor for the presence of alcohol reverted back to the level experienced previously. We maintained our reduced costs at their 2023 levels
where possible, although inflation took its toll, increasing the cost of raw materials, labor, and freight. We continued and intensified
our new product development efforts while maintaining the high level of customer service that has led to an excellent reputation for outstanding
customer service. With the introduction of new products, we believe Lifeloc will again be profitable.

 Net sales.

 Our product sales for the year ended December 31,
2024 were $8,470,985, a decrease of 8% from $9,228,843 for the same period a year ago. This decrease is primarily attributable
to having satisfied pent up demand in later 2023 and the first part of 2024. In addition, inflationary pressures on customers' budgets
also played a role. When royalties of $34,382 and rental income of $32,778 are included, total revenues of $8,538,145 decreased by
$791,421, or 9%, for the year ended December 31, 2024 when compared to the same 12 months a year ago. Rental income decreased by $35,646
due to electing not to renew or replace a lease for a portion of the space formerly occupied by a tenant, and royalties increased by $2,083
due to an increase in sales by royalty-paying customers.

 Gross profit.

 Gross profit for the year ended December 31, 2024
of $3,446,099 represented a decrease of 15% from total gross profit of $4,039,670 for the year ended December 31, 2023, primarily as a
result of lower product sales and rental income, and the inflationary effect on costs. Cost of product sales decreased from $5,260,338
in the year ended December 31, 2023 to $5,066,779 in the same period in 2024, a decrease of $193,559 (4%). Gross profit margin on
products decreased to 40% in the year ended December 31, 2024 from 43% in the year ended December 31, 2023 primarily as a result of the
sales mix.

 Research, development and sustaining engineering
expenses.

 Research, development and sustaining engineering expenses
continued at the high level of $2,242,869 for the year ended December 31, 2024, representing an increase of $407,705 (22%) over the $1,835,164
in the same period a year ago. This increase resulted primarily from the addition of personnel, materials and outside contractors
needed for our dedication of resources to SpinDx. In 2025 we expect to pay $487,300 to a third party contractor for additional
work required to complete a portion of the SpinDx development.

 Sales and marketing expenses.

 Sales and marketing expenses of $1,358,211 for the
year ended December 31, 2024 were up by $132,830 (or 11%) from the $1,225,381 spent in the same period a year ago as a result of expanded
marketing efforts, including attending trade shows and additional personnel following the decline of the pandemic and resolution of supply
chain issues.

 General and administrative expenses.

 General and administrative expenses of $1,253,236
for the year ended December 31, 2024 versus $1,170,260 for the year ended December 31, 2023 were higher by $82,976 (7%) as a result of
the effects of inflation.

 Other income (expense).

 Interest income decreased from $70,062 a year ago
to $42,867 in 2024 as a result of less funds available. Interest expense of $40,145 in the year ended December 31, 2024 was down
slightly from $41,566 in the previous year as a result of the decrease in the interest rate on our new loan on our building. The total
decrease as a result of the above items in the year ended December 31, 2024 was $25,774, or 90%, from the year ended December 31, 2023.

 Net income (loss).

 We realized a net loss
of $1,052,948 for the year ended December 31, 2024 compared to net income of $205,614 for the year ended December 31, 2023. This
decrease of $1,258,562 was the result of the changes in gross profit, operating expenses and other income discussed above, which resulted
in a loss before taxes of $1,405,495 or a decrease of $1,242,856 from the loss before taxes of $162,639 in 2023. After the benefit from
taxes of $352,547 (versus a benefit from taxes of $368,253 a year ago), we realized a net loss of $(1,052,948) compared to a net income
of $205,614 in 2023. The benefit from taxes of $352,547 resulted in an increase to our deferred tax asset from $806,652 at December 31,
2023 to $1,159,199 at December 31, 2024.

 Trends and Uncertainties That May Affect Future Results

 Revenues in the year 2024 were lower compared to revenues
in 2023. We believe that continued increased sales efforts, together with the expected availability of SpinDx for sale in
2026 may result in improved revenues in 2026 and beyond. Revenues in 2025 may be similar to revenues in 2024. Inflationary pressures
have affected our business in a number of ways, including increasing the cost of raw materials, labor, and freight. Our actions to mitigate
the impact of inflation, including pre-ordering components in higher than usual quantities, sourcing new vendors and increasing prices
have been somewhat successful.

 We expect our quarter-to-quarter revenue fluctuations
to continue, due to the unpredictable timing of large orders from customers and the size of those orders in relation to total revenues. Going
forward, we intend to focus our development efforts on products we believe offer the best prospects to increase our intermediate and near-term
revenues, with particular emphasis on completing SpinDx.

 Our 2025 operating plan is focused on growing sales,
increasing gross profits, and increasing research and development efforts on new products, including SpinDx, for long-term growth.
We cannot predict with certainty the expected sales, gross profit, net income or loss, or usage of cash and cash equivalents for 2025.
However, we believe that cash resources will be sufficient to fund our operations for the next twelve months under our current operating
plan. If we are unable to manage the business operations in line with our budget expectations, it could have a material adverse effect
on business viability, financial position, results of operations and cash flows. Further, if we are not successful in sustaining profitability
and remaining at least cash flow break-even, additional capital may be required to maintain ongoing operations.

 Interest expense.

 In connection with the financing of our building purchase
on October 31, 2014 we obtained a 10-year term loan from Bank of America in an initial principal amount of $1,581,106 bearing interest
at 4.45% per annum (which was decreased to 4% in 2016) and secured by a first-priority mortgage in the acquired property, as well as a
one-year $250,000 line of credit, which was later increased to $750,000 with a maturity date of September 28, 2021. The Bank of America
loan was paid on September 30, 2021 with proceeds from a new term loan from Citywide Banks, also secured by a first-priority mortgage
on the property, in the principal amount of $1,350,000. The new loan is payable in monthly installments of $7,453, with interest at 2.95%
and a maturity date of September 30, 2031. The revolving line of credit facility expired in accordance with its terms and has not been
renewed.

 On December 31, 2024 we issued an unsecured $750,000
subordinated debenture bearing interest at 8.25%, including 62,500 warrants exercisable for six years into 62,500 shares of our common
stock at a price of $4.50 per share. Using the Black Scholes model, the fair market value of these warrants resulted in deferred financing
cost of $120,000, which is included in our balance sheet at December 31, 2024 and which resulted in an increase to capital of $120,000.
In addition to the stated interest of 8.25%, this deferred financing cost will be a charge against income of $20,000 per year for 6 years
starting in 2025. The interest of 8.25% will be paid in quarterly increments in 2025, and will be included in monthly payments of $9,199
including principal, starting in 2026.

 Liquidity and Capital Resources

 We compete in a highly technical, very competitive
and, in most cases, price driven alcohol testing marketplace, where products can take years to develop and introduce to distributors and
end users. Furthermore, manufacturing, marketing and distribution activities are regulated by the DOT and other regulatory
bodies that, while intended to enhance the ultimate quality and functionality of products produced, can contribute to the cost and time
needed to maintain existing products and develop and introduce new products.

 Except for normal operating contractual commitments
and purchase orders, we do not have any material contractual commitments requiring settlement in the future. See "Note 5 –
Commitments and Contingencies" to our Financial Statements in Part II - Item 8.

 We have traditionally funded working capital needs
through product sales and close management of working capital components of our business. Historically, we have also received
cash from private offerings of our common stock, warrants to purchase shares of our common stock, and notes. In July, 2024 we completed
a private placement of 210,000 shares of our common stock at $3.80 per share for a total raise of $798,000 with a related party. On December
31, 2024 we completed the issuance of a six year unsecured subordinated debenture for $750,000 with a third party. In our earlier
years, we incurred quarter to quarter operating losses to develop current product applications, utilizing a number of proprietary and
patent-pending technologies. Although we have been profitable in recent years except 2020, 2022 and 2024, we can provide no
assurances that operating losses will not occur in the future. Should that situation arise, we may not be able to obtain working
capital funds necessary in the time frame needed and at satisfactory terms, if at all.

 As of December 31, 2024, cash and cash equivalents
were $1,243,746, trade accounts receivable were $732,541 and current liabilities were $743,575 resulting in net liquid assets of $1,232,712. We
believe that the diminishing of the Covid-19 pandemic, the resolution of supply chain issues, and the introduction of several new products
during the last several years, along with new and on-going customer relationships will allow Lifeloc to operate profitably. If the
revenue levels prior to 2020 do not continue to increase in a timely manner, if inflationary pressures are not contained, or if the development
and market acceptance of SpinDx takes longer than expected, we may be required to seek additional sources of capital and/or to
implement further cost reduction measures, as necessary.

 Equipment expenditures, consisting of updated production
equipment and SpinDx related equipment, during FY 24 were $667,738 compared to $6,811 for FY 23, an increase of $660,927. We incurred
patent application costs in preparation for filing of $21,708 in 2024 versus $1,404 in 2023. No expired or fully amortized patents were
removed from our financial statements in 2024 or 2023. As development of SpinDx progresses, and as normal wear and tear of equipment occurs,
we expect to incur outlays for equipment and patent filings in 2025 and beyond.

 We generally provide a standard one-year limited warranty
on materials and workmanship to our customers. We provide for estimated warranty costs at the time product revenue is recognized. Warranty
costs are included as a component of cost of goods sold in the accompanying statements of operations. For the year ended December
31, 2024 and for the year ended December 31, 2023, warranty costs were not deemed significant.

 Critical Accounting Policies and Estimates

 Our financial statements and accompanying notes have
been prepared in accordance with United States generally accepted accounting principles applied on a consistent basis. The preparation
of financial statements in conformity with United States generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the
date of the financial statements and the reported amounts of revenues and expenses during the reporting periods.

 We regularly evaluate the accounting policies and
estimates that we use to prepare our financial statements. In general, management's estimates are based on historical experience,
on information from third party professionals, and on various other assumptions that are believed to be reasonable under the facts and
circumstances. Actual results could differ from those estimates made by management.

 Our discussion and analysis of our financial condition
and results of operations are based upon our financial statements, which have been prepared in accordance with accounting principles generally
accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that
affect the reported amounts of assets, liabilities, sales and expenses, and related disclosure of contingent assets and liabilities. On
an on-going basis, we evaluate our estimates, including those related to bad debts, inventories, sales returns, warranty, contingencies
and litigation. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable
under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities
that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions
or conditions. We believe the following critical accounting policies affect the more significant judgments and estimates used
in the preparation of our financial statements.

 We have concluded that we have two operating segments,
including our primary business which is as a developer, manufacturer and marketer of portable hand-held breathalyzers and related accessories,
supplies and education, and a second segment consisting of renting portions of our building to existing tenants.

 We maintain allowances for doubtful accounts for estimated
losses resulting from the inability of our customers to make required payments. If the financial condition of our customers
were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances would be required, which would
increase our expenses during the periods in which any such allowances were made. The amount recorded as a provision for bad
debts in each period is based upon our assessment of the likelihood that we will be paid on our outstanding receivables, based on customer-specific
as well as general considerations. To the extent that our estimates prove to be too high, and we ultimately collect a receivable
previously determined to be impaired, we may record a reversal of the provision in the period of such determination.

 We reduce inventory for estimated obsolete or unmarketable inventory equal to the difference between the cost of inventory and the estimated market value based upon assumptions about future demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required. Any write-downs of inventory would reduce our reported net income during the period in which such write-downs were applied.

 Property and equipment are stated at cost, with depreciation
computed over the estimated useful lives of the assets, generally five years (three years for software and technology licenses).
We use the declining method of depreciation for property, including space modifications, and the straight line method for software and
technology licenses. We purchased all of the assets of STS, an online education company, in 2014, which consisted of training courses
that are amortized over 15 years using the straight line method. In October 2014, we purchased our building. A majority of the cost
of the building is depreciated over 39 years using the straight line method. In addition, based on the results of a third party analysis,
a portion of the cost was allocated to components integral to the building. Such components are depreciated over 5 and 15 years,
using the declining method. The R.A.D.A.R. software and patents that were purchased in March 2017 were originally set to amortize
over 15 years using the straight line method, but in 2022 we accelerated the amortization of the remaining cost to fully amortize the
assets by December 31, 2024. Maintenance and repairs are expensed as incurred and major additions, replacements and improvements are capitalized.

 Revenue from product sales and supplies is generally
recorded when we ship the product and title has passed to the customer, or when agreed milestones are met in the case of product developments,
provided that we have evidence of a customer arrangement and can conclude that collection is probable. The prices at which
we sell our products are fixed and determinable at the time we accept a customer's order. We recognize revenue from sales to stocking
distributors when there is no right of return, other than for normal warranty claims, and generally have no ongoing obligations related
to product sales, except for normal warranty.

 The sales of licenses to our training courses are
recognized as revenue at the time of sale. Direct training performed by us is recognized when training is completed by the trainer, with
the unearned portion classified as deferred revenue. Training and certification revenues are recognized at the time the training and certification occurs.
Data recording revenue is recognized based on each day's usage of enrolled devices.

 Revenues arising from extended warranty contracts
are booked as sales over their life on a straight-line basis. We provide customer financing and leasing ourselves, which we recognize
as revenue over the applicable lease term. Occasionally, we rent used equipment to customers, and in those cases, we recognize
the revenues as they are earned over the life of the contract.

 Royalty income is recognized in accordance with agreed
upon terms, when performance obligations are satisfied, the amount is fixed or determinable and collectability is reasonably assured.

 Rental income from space leased to our tenants is
recognized in the month in which it is due.

 On occasion we receive customer deposits for future
product orders and for product development. Customer deposits are initially recorded as a liability and recognized as revenue
when the product is shipped and title has passed to the customer, or in the case of product development, when agreed milestones are met.

 Stock-based compensation is presented in accordance
with the guidance of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic
718, Compensation — Stock Compensation ("ASC 718"). Under the provisions of ASC 718, companies are required
to estimate the fair value of share-based payment awards made to employees and directors including employee stock options based on estimated
fair values on the date of grant using an option-pricing model. The value of the portion of the award that is ultimately expected
to vest is recognized as expense over the requisite service periods in our statement of operations.

 Off-Balance Sheet Arrangements

 We currently have no off-balance sheet arrangements
that have or are reasonably likely to have a current or future material effect on our financial condition, changes in financial condition,
revenues or expenses, results of operations, liquidity, capital expenditures or capital resources.

 1. ORGANIZATION AND NATURE OF BUSINESS

 Lifeloc Technologies, Inc. ("Lifeloc" or
the "Company", "Us", "Our", or "We") is a Colorado-based developer, manufacturer and
marketer of portable hand-held and fixed station breathalyzers and related accessories, supplies and education. We design, produce
and sell fuel-cell based breath alcohol testing equipment. We compete in all major segments of the breath alcohol testing instrument
market, including law enforcement, workplace, corrections, original equipment manufacturing ("OEM") and consumer markets. In
addition, we offer a line of supplies, accessories, services, and training to support customers' alcohol testing programs. We sell globally
through distributors as well as directly to users.

 We define our business as providing "near and
remote sensing and monitoring" products and solutions. Today, the majority of our revenues are derived from products and services
for alcohol detection and measurement. We remain committed to growing our breath alcohol testing business. In the future, we anticipate
the commercialization of new sensing and measurement products that may allow Lifeloc to successfully expand our business into new growth
areas where we do not presently compete or where no satisfactory product solutions exist today.

 Lifeloc incorporated in Colorado in December 1983. We
filed a registration statement on Form 10 with the Securities and Exchange Commission, which became effective on May 31, 2011. Our
fiscal year end is December 31. Our principal executive offices are located at 12441 West 49th Avenue, Unit 4, Wheat Ridge, Colorado
80033-3338. Our telephone number is (303) 431-9500. Our websites are www.lifeloc.com and www.stsfirst.com.

 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

 Use of Estimates in the Preparation of Financial
Statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United
States requires management to make estimates and assumptions regarding allowances for bad debts, inventory obsolescence, accumulated depreciation,
and deferred income taxes. Such estimates and assumptions affect the reported amounts of assets and liabilities as well as disclosure
of contingent assets and liabilities at the date of the financial statements and the reported amounts of sales and expense during the
reporting period. Actual results could differ from those estimates.

 Debt Issuance Costs. The term loan is shown
in the accompanying balance sheet net of debt issuance costs. Deferred debt issuance costs are amortized over the life of the term loan
on a straight line basis, which approximates the effective interest method. Total debt issuance cost amortization during the years
ended December 31, 2024 and 2023 was $ 4,254 and $ 4,304 respectively, and is included within interest expense on the statements of income
(loss).

 Deferred Income Taxes. Deferred
income tax assets and liabilities are presented as noncurrent assets or liabilities in the balance sheet.

 Fair Value Measurement. Accounting Standards
Codification ("ASC") Topic 820, Fair Value Measurements and Disclosures ("ASC 820"), provides a comprehensive
framework for measuring fair value and expands disclosures which are required about fair value measurements. Specifically, ASC 820 sets
forth a definition of fair value and establishes a hierarchy prioritizing the inputs to valuation techniques, giving the highest priority
to quoted prices in active markets for identical assets and liabilities and the lowest priority to unobservable value inputs. ASC 820
defines the hierarchy as follows:

 Level 1 - Quoted prices are available in active markets
for identical assets or liabilities as of the reported date. The types of assets and liabilities included in Level 1 are highly liquid
and actively traded instruments with quoted prices, such as equity securities listed on the New York Stock Exchange.

 Level 2 - Pricing inputs are other than quoted prices
in active markets, but are either directly or indirectly observable as of the reported date. The types of assets and liabilities in Level
2 are typically either comparable to actively traded securities or contracts or priced with models using highly observable inputs.

 Level 3 - Significant inputs to pricing that are unobservable as of the reporting date. The types of assets and liabilities included in Level 3 are those with inputs requiring significant management judgment or estimation, such as complex and subjective models and forecasts used to determine the fair value of financial transmission rights. At December 31, 2024 and 2023, the Company has no assets and no liabilities that are remeasured at fair value on a recurring or nonrecurring basis.

 Cash and Cash Equivalents. For purposes
of reporting cash flows, we consider all cash and highly liquid investments with an original maturity of three months or less to be cash
equivalents.

 Fair Value of Financial Instruments.
Our financial instruments consist of cash, a term loan secured by a first mortgage, and an unsecured subordinated debenture. The
carrying values of cash, their fair value due to their short term maturities. The carrying value of the term loan approximates its
fair value based on interest rates currently obtainable. The carrying value of the debenture approximates its fair value after allocating
a portion to the attached warrants.

 Concentration of Credit Risk. Financial
instruments with significant credit risk include accounts receivable.

 We have no significant off-balance sheet concentrations
of credit risk such as foreign exchange contracts, options contracts or other foreign hedging arrangements.

 Accounts Receivable. Accounts receivable
are typically unsecured and are derived from transactions with and from entities primarily located in the United States or from international
distributors with a proven payment history. Accordingly, we may be exposed to credit risks generally associated with the alcohol
monitoring industry. Our credit policy calls for payment in accordance with prevailing industry standards, generally 30 days
with occasional exceptions of up to 60 days for large established customers. We maintain allowances for doubtful accounts for
estimated losses resulting from the inability of our customers to make required payments. A summary of the activity in our
allowance for doubtful accounts is as follows:

2024 of $ 732,541 included an account from one customer of $ 339,925 (46%), $ 27,383 (4%) from a second customer, $ 19,684 from a third customer
(3%), and no more than 3% from any other single customer. The net accounts receivable balance at December 31, 2023 of $ 812,126 included
an account from one customer of $ 103,739 (13%), $ 98,412 from a second customer (12%), $ 42,594 from a third customer 5%, and no more than
5% from any other single customer.

 Inventories. Inventories are stated
at the lower of standard cost or net realizable value. We reduce inventory for estimated obsolete or unmarketable inventory equal to the
difference between the cost of inventory and the estimated net realizable value after cost to sell, based upon assumptions about future
demand and market conditions. If actual market conditions are less favorable than those projected by management, additional inventory
write-downs may be required. At December 31, 2024 and December 31, 2023, inventory consisted of the following:

 Property, Plant and
Equipment. Property, plant and equipment are stated at cost, with depreciation computed over the estimated useful lives
of the assets, generally five years; three years for software and technology licenses; 15 years for space modifications and for training
courses; 39 years for the cost of the building we purchased in October 2014. We utilize the declining balance method of depreciation for
property, equipment and space modifications, and the straight-line method of depreciation for software, training courses, and the building,
due to the expected usage of these assets over time. These methods are expected to continue throughout the life of the assets. Maintenance
and repairs are expensed as incurred and major additions, replacements and improvements are capitalized. Depreciation expense for
the years ended December 31, 2024 and 2023 was $ 286,815 and $ 253,876 respectively. No depreciation is recorded on equipment, software
and space modifications not in service until such time as they are placed in service. Gain or loss on property, plant and equipment that
is disposed of is recognized in operations in the statements of income (loss).

 Impairment of Long-Lived Assets. Long-lived
assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be
recoverable. A long-lived asset is considered impaired when estimated future cash flows related to the asset, undiscounted and without
interest, are insufficient to recover the carrying amount of the asset. If deemed impaired, the long-lived asset is reduced to its estimated
fair value. Long-lived assets to be disposed of are reported at the lower of their carrying amount or estimated fair value less cost to
sell. No impairments were recorded for the years ended December 31, 2024 and 2023 respectively.

 Patents. The costs of applying
for patents are capitalized and amortized on a straight-line basis over the lesser of the patent's economic or legal life (20 years for
utility patents in the United States, and 14 years for design patents). Amortization expense for the years ended December 31, 2024
and 2023, was $ 7,424 and $ 6,644 respectively. Amortization expense for each of the next 5 years is estimated to be $ 14,273 per year. Capitalized
costs are expensed if patents are no t granted. We review the carrying value of our patents periodically to determine whether the
patents have continuing value and such reviews could result in the conclusion that the recorded amounts have been impaired. No impairments
were included in amortization expense for the years ended December 31, 2024 and 2023 respectively. A summary of our patents at December
31, 2024 and 2023 is as follows:

 Product Warranty Reserve. We provide

and will be affected by product failure rates and material usage incurred in correcting a product failure. Should actual product failure
rates or material usage costs differ from our estimates, revisions to the estimated warranty liability would be required. A

 Income Taxes. We account for income
taxes under the provisions of ASC Topic 740, Accounting for Income Taxes ("ASC 740"). ASC 740 requires recognition of
deferred income tax assets and liabilities for the expected future income tax consequences, based on enacted tax laws, of temporary differences
between the financial reporting and tax bases of assets and liabilities. ASC 740 also requires recognition of deferred tax assets for
the expected future tax effects of all deductible temporary differences, loss carryforwards and tax credit carryforwards. Deferred
tax assets are then reduced, if deemed necessary, by a valuation allowance for the amount of any tax benefits which, more likely than
not based on current circumstances, are not expected to be realized.

 ASC 740 prescribes a comprehensive model for how companies should recognize, measure, present, and disclose in their financial statements, uncertain tax positions taken or expected to be taken on a tax return. Under ASC 740, tax positions must initially be recognized in the financial statements when it is more likely than not the position will be sustained upon examination by the tax authorities. Such tax positions must initially and subsequently be measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority assuming full knowledge of the position and relevant facts. For the years ended December 31, 2024 and 2023, we did no t have any significant interest or penalties associated with uncertain tax positions.

 Revenue Recognition. Revenue from product
sales and supplies is generally recorded when we ship the product and title has passed to the customer, or when agreed milestones are
met in the case of product developments, provided that we have evidence of a customer arrangement and can conclude that collection is
probable. The prices at which we sell our products are fixed and determinable at the time we accept a customer's order. We
recognize revenue from sales to stocking distributors when there is no right of return, other than for normal warranty claims, and generally
have no ongoing obligations related to product sales, except for normal warranty.

 The sales of licenses to our training courses are
recognized as revenue at the time of sale. Training and certification revenues are recognized at the time the training and certification occurs.
Data recording revenue is recognized based on each day's usage of enrolled devices.

 Revenues arising from extended warranty contracts
are booked as sales over their life on a straight-line basis. We have discontinued arranging for customer financing and leasing through
unrelated third parties and instead are providing for customer financing and leasing ourselves, which we recognize as revenue over the
applicable lease term. Occasionally, we rent used equipment to customers, and in those cases, we recognize the revenues as
they are earned over the life of the contract.

 Royalty income is recognized in accordance with agreed
upon terms, when performance obligations are satisfied, the amount is fixed or determinable and collectability is reasonably assured.

 Rental income from 2,774 square feet of space leased
to our tenant is recognized in the month in which it is due, which approximates if it were recognized on a straight-line basis over the
term of the related lease. The lease expires on June 30, 2025 and does not have an option to renew.

 On occasion we receive customer deposits for future
product orders and product developments. Customer deposits are initially recorded as a liability and recognized as revenue
when the product is shipped and title has passed to the customer, or when agreed milestones are met in the case of product developments.

 The following is the disaggregation of revenue into
broad categories, which we have defined as shown below.

 Deferred Revenue. Deferred
revenues arise from service contracts and from direct training revenue. Revenues from service contracts are recognized
on a straight-line basis over the life of the contract, generally one year, and are included in product revenue in our statements of income
(loss). However, there are occasions when they are written for longer terms up to four years. The revenues from that portion
of the contract that extend beyond one year are shown in our balance sheets as long term. Deferred revenues also result from direct
training revenue that needs to be scheduled based on the customer's and Lifeloc's availability. Revenue is recognized when
training is complete and is included in product sales in our statements of income. All direct training are for less than one
year and all deferred revenues from this source are shown in our balance sheets as short term.

 Rebates. Our rebate program is available
to certain of our North American workplace distributors in good standing who are responsible for sales equaling at least $25,000 in one
calendar year. Distributors in good standing who meet the required sales threshold earn a rebate equal to between 1 and 10
percent of that distributor's total sales of the Company's products. We accrue for these rebates monthly; they are shown in
our balance sheets as accrued expenses. We paid $ 35,502 and $ 34,051 of rebates for the years ending December 31, 2024 and 2023 respectively.

 Recently Issued Accounting Pronouncements.

 In November 2023, the FASB issued ASU 2023-07, Segment
Reporting (Topic 280): Improvements to Reportable Segment Disclosures, amending reportable segment disclosure requirements to include
disclosure of incremental segment information on an annual and interim basis. Among the disclosure enhancements are new disclosures regarding
significant segment expenses that are regularly provided to the chief operating decision-maker and included within each reported measure
of segment profit or loss, as well as other segment items bridging segment revenue to each reported measure of segment profit or loss.
The amendments in ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal
years beginning after December 15, 2024, and are applied retrospectively. Early adoption is permitted. See Note 10 for changes to our
reportable segment disclosures.

 In December 2023, the FASB issued ASU 2023-09, Income
Taxes (Topic 740): Improvement to Income Tax Disclosures, amending income tax disclosure requirements for the effective tax rate reconciliation
and income taxes paid. The amendments in ASU 2023-09 are effective for fiscal years beginning after December 15, 2024 and are applied
prospectively. Early adoption and retrospective application of the amendments are permitted. We continue to evaluate the impact of this
update on our financial statements, but do not expect any changes to our current reportable segments.

 In November 2024, the FASB issued ASU 2024-03, Income
Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement
Expenses, which requires disclosure about the types of costs and expenses included in certain expense captions presented on the income
statement. The new disclosure requirements are effective for the Company's annual periods for fiscal years beginning after December 15,
2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted, and may be applied either
prospectively or retrospectively. We are currently evaluating the ASU to determine its impact on our consolidated financial statements
and disclosures.

 The Company does not believe that issued, but not
yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company's financial statements.

 Research and Development Expenses. Equipment,
software and space modifications used for research and development that have an alternative future use are capitalized in property, plant
and equipment in the balance sheets. Equipment, software and space modifications used for research and development that have no alternative
future use are expensed as research and development costs as incurred.

 Stock-Based Compensation. Stock-based
compensation is presented in accordance with the guidance of ASC Topic 718, Compensation – Stock Compensation ("ASC
718"). Under the provisions of ASC 718, companies are required to estimate the fair value of share-based payment awards
on the date of grant based on the trading price of stock issued. The value of the portion of the award that is ultimately expected
to vest is recognized as expense over the requisite service periods in our statement of income.

 ASC 718 requires companies to estimate the fair value
of share-based payment awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is
recognized as expense on a straight line basis over the requisite service periods in the accompanying statement of income (loss). Forfeitures
are recognized as they occur.

 Segment Reporting. We have concluded
that we have two operating segments, including our primary business which is as a developer, manufacturer and marketer of portable hand-held
breathalyzers and related accessories, supplies and education. As a result of purchasing our building on October 31, 2014, we have
a second segment consisting of renting portions of our building to one tenant, whose lease expires on June 30, 2025.

 Accounting Standards Update 2023-07 requires significant
segment expenses be disclosed for each reportable segment. See Note 10 for a table showing expense allocations for our product sales segment.

 The chief operating decision maker evaluates the performance
of the Company's reportable segments based on segment profit or loss from operations, which is inclusive of all respective expenses.
The profitability target of each segment is at the profit or loss from operations level, which is how the chief operating decision maker
assesses performance. The chief operating decision maker also uses profit or loss from operations to allocate capital and personnel to
the segments, which is typically done to improve the efficiency and effectiveness of operations or for expansion of operations, and ultimately
to increase profit from operations. The Company's reportable segments are strategic business units that offer different products.
They are managed separately because each business requires different expertise to ensure quality products are produced in an efficient
manner and because each business has a different customer base. We view our rentals segment as immaterial as the chief operating decision
maker is focused primarily on the products segment. The Company's chief operating decision maker is the chief executive officer.

 3. BASIC AND DILUTED INCOME AND LOSS PER COMMON SHARE

 We report both basic and diluted net income or loss per common share. Basic net income or loss per common share is computed by dividing net income or loss for the period by the weighted average number of common shares outstanding for the period. Diluted net income or loss per common share is computed by dividing the net income or loss for the period by the weighted average number of common and potential common shares outstanding during the period if the effect of the potential common shares is dilutive. The shares used in the calculation of dilutive potential common shares exclude options and warrants to purchase shares where the exercise price was greater than the average market price of common shares for the period.

 The following table presents the calculation of basic and diluted net income
(loss) per common share:

 4. STOCKHOLDERS' EQUITY

 Stock Option Plan. In January 2013,
we adopted our 2013 Stock Option Plan (the "2013 Plan") to promote the Company's and its stockholders' interests by helping
us to attract, retain and motivate our key employees and associates. Under the terms of the 2013 Plan, our Board of Directors (the "Board")
can grant either "nonqualified" or "incentive" stock options, as defined by the Internal Revenue Code and related
regulations. The purchase price of the shares subject to a stock option is the fair market value of our common stock on the date the stock
option is granted. Generally, all stock options must be exercised within five years from the date granted. No common shares
are reserved for issuance under the 2013 Plan as it has expired. The 2013 Plan was approved by our shareholders at their regular annual
meeting on April 1, 2013.

 A summary of our stock option activity and related
information for equity compensation plans approved by security holders for each of the fiscal years ended December 31, 2024 and 2023 is
as follows:

 The options outstanding at December 31, 2024 are fully vested and have
a weighted average life of 0.56 years.

 The options outstanding at December 31, 2024 had an intrinsic value of
$ 0.

 The exercise price of all options granted through
December 31, 2024 has been equal to or greater than the fair market value as of the date of grant, as determined by the Board. As
of December 31, 2024, no options for our common stock remain available for grant under the 2013 Plan as it has expired.

 No options were exercised during the years ended December
31, 2024 and 2023.

 At December 31, 2024 there were 62,500 warrants outstanding
with a life of 6 years and with an exercise price of $ 4.50. There were no warrants outstanding at December 31, 2023.

 5. DEBT

 Debenture. On December 31, 2024 we issued a
$ 750,000 debenture subordinated to obligations to the Company's general and secured creditors that calls for interest only at 8.25 %
payable quarterly in the first year, with monthly payments of $ 9,199 including principal and interest at 8.25% commencing in the second
year based on a ten year amortization schedule. A balloon payment of $ 451,012 is due in full on December 31, 2030.

 In consideration of the lender providing the financing,
the Company issued warrants which entitle the holder to purchase 62,500 shares of our common stock at $ 4.50 per share. The warrants were
immediately and fully vested, and have a life of 6 years. If the debenture is paid in full on or before December 31, 2029, the warrants
will have a life of five years.

 The factors used to calculate the estimated value
of the warrants and the resulting fair market value, were as follows.

COMMITMENTS AND
CONTINGENCIES.

 Employee Severance Benefits. Our obligation
with respect to employee severance benefits is minimized by the "at will" nature of the employee relationships. As
of December 31, 2024 we had no obligation with respect to contingent severance benefit obligations other than the Company's obligations
under the employment agreement with its chief executive officer, Dr. Wayne Willkomm. In the event that Dr. Willkomm's employment is terminated
by the Company without Cause (including through a decision by the Company not to renew the employment agreement) or by Dr. Willkomm with
Good Reason (as each are defined in the employment agreement), Dr. Willkomm will be eligible, upon satisfaction of certain conditions,
for severance equal to two months of salary continuation plus 12 months of health insurance continuation.

 Contractual Commitments and Purchase Orders.
Contractual commitments under development agreements and outstanding purchase orders issued to vendors in the ordinary course of business
totaled $ 2,025,429 at December 31, 2024.

 Regulatory Commitments.
We are subject to certain regulations of the United States Department of Transportation and various state departments of transportation. We
believe that we are in substantial compliance with all known applicable regulations.

 Management assesses the available positive and negative
evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. On
the basis of this evaluation, as of December 31, 2024, a valuation allowance of $ 187,234 has been recorded to recognize only the portion
of the deferred tax asset that is more likely than not to be realized. The amount of the deferred tax asset considered realizable, however,
could be adjusted if estimates of future taxable income during the carryforward period are reduced or increased.

 The items accounting for the difference between income taxes computed at

 The Company has an Increasing Research Activities Credit
carryover of $ 237,166 which expires between the years 2039 through 2044. Our income tax filings in the United States and state jurisdictions
are open to examination for the 2022 – 2024 tax years. Tax attributes from years prior to that can be adjusted as a result of examinations.
In the event we are assessed penalties and or interest, penalties will be charged to other operating expense and interest will be charged
to interest expense. The Company has reviewed its tax positions and believes it has not taken a position that would not be sustained under
examination.

 8. LEGAL PROCEEDINGS

 We were not involved or party to any legal proceedings
at December 31, 2024 or December 31, 2023, and therefore made no accruals for legal proceedings in either 2024 or 2023.

 9. MAJOR CUSTOMERS/SUPPLIERS

 We depend on sales that are generated from our customers'
ongoing usage of alcohol testing instruments.

 One customer contributed 9 % ($ 765,562) to our product
sales in 2024, a second customer contributed 4 % ($ 333,185), a third customer contributed 2 % ($ 269,513), and no other customer contributed
more than 2%. One customer contributed 9 % ($ 790,495) to our total sales in 2023, a second customer contributed 4 % ($ 405,003), a third
customer contributed 2 % ($ 201,163), and no other customer contributed more than 3%. In making this determination, we considered the federal
government, state governments, local governments, and foreign governments each as a single customer.

 In 2024, we depended upon three vendors for approximately
 27 % of our purchases (three vendors and 28 % respectively in 2023).

 10. DEFINED CONTRIBUTION EMPLOYEE BENEFIT
PLAN

 We have adopted a 401(k) Profit Sharing Plan
("401(k) Plan") which covers all full-time employees who have completed 3 months of full-time continuous service and are age
eighteen or older. Participants may defer up to 100% of their gross pay up to 401(k) Plan limits. Participants are immediately
vested in their contributions. We make monthly discretionary matching contributions of 3 % of the total payroll of the participating
employees. In 2024 and 2023 we contributed $ 69,678 and $ 64,608 respectively. The participants vest in Company contributions
based on years of service, with a participant fully vested after six years of credited service.

 11. BUSINESS SEGMENTS

 We currently have two business segments: (i) the sale of physical products, including portable hand-held breathalyzers and related accessories, supplies, education, training ("Product Sales"), and royalties from development contracts with OEM manufacturers ("Royalties" and, together with Product Sales, the "Products" segment), and (ii) rental of a portion of our building (the "Rentals" segment). The accounting policies of the segments are the same as those described in the summary of significant accounting policies in Note 2.

 Operating profits for these segments exclude unallocated
corporate items. Administrative and staff costs were commonly used by all business segments and were indistinguishable.

 The following sets forth information about the operations
of the business segments for the years ended December 31, 2024 and 2023.

 Accounting Standards Update 2023-07 requires
all public entities to disclose significant segment expenses for each reportable segment. We have excluded our rentals segment and allocated
all expenses to the products segment in the table below as the rentals segment is immaterial. Similarly, royalties are excluded as none
of the expenses are attributable to royalties.

 12. SUBSEQUENT EVENTS

 We evaluated all of our activity and concluded that
no subsequent events have occurred that would require recognition in our financial statements or disclosure in the notes to our financial
statements, except as follows.

 In January, 2025 we issued our purchase order totaling
$487,300 for additional work required to complete a portion of the SpinDx development performed by outside contractors.

 In February, 2025 options to purchase 88,500 shares
of our common stock were exercised at a price of $ 3.80 per share for total proceeds of $ 336,300. Our president and CEO exercised 37,500
options, and 2 directors exercised 1,000 options each. EDCO Partners, LLLP, of which the CFO and a director is the general partner and
a third director provided $ 136,040 to enable selected option holders to exercise and simultaneously sell their shares to EDCO Partners
and to the third director.

 In March, 2025 a $ 75,000 subordinated debenture was
issued to an unrelated party who is also a limited partner of EDCO Partners LLLP. The terms of the debenture provide for interest at 8.25 % per annum, with interest only payable in 2025, and monthly payments commencing in 2026 based on a ten year amortization schedule
with the balance due in full on December 31, 2030. Warrants entitling the holder to purchase 6,250 shares of our common stock at $ 4.50
apiece were attached.

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

 None.

 Item 9A. Controls and Procedures

 Evaluation of Disclosure Controls and Procedures

 As of the end of the period covered by this Annual
Report on Form 10-K, our management has evaluated, under the supervision and with the participation of our Chief Executive Officer and
Chief Financial Officer, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e)
under the Securities Exchange Act of 1934) (the "Exchange Act"). Disclosure controls and procedures are designed to ensure
that information required to be disclosed in our reports filed under the Exchange Act is recorded, processed, summarized and reported
within the time periods specified in the Securities and Exchange Commission's ("SEC") rules and forms and that such information
is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely
decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded
that our disclosure controls and procedures were effective as of December 31, 2024.

 Internal Control over Financial Reporting

 (a)
 Management's
Annual Report on Internal Control over Financial Reporting

 Our management is responsible for establishing and
maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange
Act. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. 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. Under the supervision and with the participation
of our management, including our Chief Executive Officer and our Chief Financial Officer, we conducted an evaluation of the effectiveness
of our internal control over financial reporting as of December 31, 2024 based on the criteria in Internal Control-Integrated Framework
 issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in 2014. Based on our evaluation
under the framework in Internal Control-Integrated Framework issued by the COSO in 2014, our management concluded that our internal
control over financial reporting was effective as of December 31, 2024.

 (b)
 Attestation
report of the registered public accounting firm.

 This Annual Report does not include an attestation
report of our independent registered public accounting firm regarding internal control over financial reporting. Management's report was
not subject to attestation by our independent registered public accounting firm pursuant to rules of the SEC, which permit us to provide
only management's report in this Annual Report.

 (c)
 Changes in Internal
Control over Financial Reporting

 There were no significant changes in our internal
controls over financial reporting during the quarter ended December 31, 2024 that have materially affected, or that are reasonably likely
to materially affect, our internal control over financial reporting.

 Limitations on the Effectiveness of Controls

 A control system, no matter how well designed and
operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. Our management,
including our Chief Executive Officer and our Chief Financial Officer, do not expect that the Company's disclosure controls will prevent
or detect all errors and all fraud. Further, the design of a control system must reflect the fact that there are resource constraints,
and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control
systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company
have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that
breakdowns can occur because of simple error or mistake. Controls can also be circumvented by the individual acts of some persons,
by collusion of two or more people, or by management override of the controls. The design of any system of controls is based
in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in
achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes
in conditions or deterioration in the degree of compliance with associated policies or procedures. Because of the inherent
limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

 Item 9B. Other Information
