 ITEM 1. BUSINESS

 Gresham Worldwide, Inc., formerly Giga-tronics, Incorporated ("Gresham" or the "Company") designs, manufactures and distributes purpose-built electronics equipment, automated test solutions, power electronics, supply and distribution solutions, as well as radio, microwave and millimeter wave communication systems and components for a variety of applications with a focus on the global defense industry and the healthcare market.

 Gresham has two subsidiaries Gresham Holdings, Inc. ("Gresham Holdings") and Microsource Inc. ("Microsource"). Gresham has also one division. Gresham is a majority-owned subsidiary of Ault Alliance, Inc., a Delaware corporation ("AAI") and currently operates as an operating segment of AAI. Gresham Holdings has three wholly-owned subsidiaries, Gresham Power Electronics Ltd. ("Gresham Power"), Relec Electronics Ltd. ("Relec"), and Enertec Systems 2001 Ltd. ("Enertec"), and one majority-owned subsidiary, Microphase Corporation ("Microphase"). Our operations consist of three business segments:

 • Radio Frequency Solutions ("RF Solutions") – consists of Microphase which is located in Connecticut. Microphase designs and manufactures custom microwave hardware products for military applications and generates revenue primarily through production contracts for custom engineered components and RADAR filters.

 • Precision Electronic Solutions – consists of two subsidiaries and one division. The subsidiaries are Enertec located in Israel and Microsource located in California. The division is what we call our Giga-tronics Division. Enertec develops and supplies advanced command & control, test and calibration systems for use in failsafe military and medical applications. The legacy business of Giga-tronics (the "Giga-tronics Business") consists of Microsource, a wholly-owned subsidiary which develops and manufactures sophisticated RADAR filters used in fighter aircraft, and our Giga-tronics Division which markets "EW Test and Training", which serves the defense electronics market with a signal generation platform.

 • Power Electronics & Displays – consists of two subsidiaries, namely Relec and Gresham Power located in the United Kingdom (the "UK") which primarily engineer and provide integrated, mobile power electronics and display solutions that distribute and supply continuous, dependable, clean low voltage power.

 We are focused on products that are getting designed in to military systems such as fighter jet, ships and ground vehicles or missiles, which provide a recurring revenue stream for years to come and eliminate competition because the cost of replacing designed in products is prohibitive for both the competition and the customer.

 Gresham was incorporated in California on March 5, 1980 as Giga-tronics Incorporated. We changed our name to Gresham effective March 1, 2024. Our common stock continues to trade under the Giga-tronics name and symbol "GIGA" on the OTCQB. We have obtained shareholder

 approval to reincorporate in Delaware. Both our name change and reincorporation are subject to Financial Industry Regulatory Authority approval.

 Business Combination

 On September 8, 2022 (the "Closing Date"), we acquired Gresham Holdings. We refer to this transaction as the "Business Combination." Pursuant to the Business Combination, the Company acquired all of the outstanding shares of capital stock of Gresham Holdings and, in exchange the Company issued AAI 2,920,085 shares of the Company's common stock and 514.8 shares of Series F preferred stock ("Series F") that are convertible into an aggregate of 3,960,043 shares of the Company's common stock, subject to potential adjustments, and the assumption of Gresham's outstanding equity awards representing, on an as-assumed basis, 749,626 shares of the Company's common stock. AAI beneficially owns 69.6% of the Company's outstanding shares (excluding shares issuable upon conversion of convertible notes described elsewhere in this Report). The parties had previously entered into a Share Exchange Agreement dated December 27, 2021 (the "Agreement") for which the Company obtained the requisite stockholder approval on September 8, 2022.

 In connection with the consummation of the Business Combination, Gresham Holdings was deemed to be the accounting acquirer in the Business Combination based on an analysis of the criteria outlined in Accounting Standards Codification 805 "Business Combinations". While we were the legal acquirer in the Business Combination, because Gresham Holdings was deemed the accounting acquirer, the historical financial statements of Gresham Holdings became the historical financial statements of the combined company, upon the consummation of the Business Combination.

 We operate both within the United States (the "U.S.") and at three locations abroad. A summary of our locations and high level review of our operations at each facility is provided in the table below:

 Our Industry

 Our operations focus exclusively on the market for electronic solutions that support the defense industry and other mission critical applications, including medical technology, transportation, and telecommunication. The essential nature of these applications provides a degree of insulation from volatility associated with other segments of the global economy while accounting for stability and steady growth of the addressable market opportunities available in segments that we serve. Demand for solutions to meet these requirements continues unaffected, and in many instances increases, in times of global crisis. Total defense spending in the three countries in which we currently operate was expected to total more than an estimated $919 billion in 2023 (  We sell to the militaries and defense contractors in 15 other countries as well. Overall global defense spending hit $2.1 trillion in 2023 and is expected to grow at a CAGR of 3% through 2028 with U.S. spending continuing to lead the world in the same period (ASD Reports, Global Defense Budget Analysis - Forecast to 2028). The current wars in the Ukraine and Israel and tensions with China and in the Middle East have intensified interest and investment in defense platforms throughout the UK and Europe.

 We believe that the increasing emphasis on electromagnetic spectrum operations and close coordination of air, land, sea, space and cyber operations will fuel an increase in defense modernization, force protection and situational awareness, all of which will drive increased spending in procurement of components and systems to enable electronic warfare, countermeasures and unattended solutions. The Defense Electronics Market was estimated to be $220.3 billion in 2023 and is projected to reach $ 289.0 billion by 2028, at a CAGR of 5.6%. (  The drive for greater connectivity and analytics will in turn increase demand for radio frequency ("RF") communications, power electronics and electronic control solutions content in new major military platforms, which are the core offerings of our operating units.

 Thousands of companies compete in this market to deliver electronics solutions to meet defense and other mission critical applications. However, our operating units have longstanding relationships with dominant defense contractors in the U.S., in the UK, in Israel and other countries who hold contracts for major defense platforms with very long life cycles. Our customers typically have unique needs, and they engage with Gresham in funding development contracts for custom solutions. Once a solution is proven in its application, the company typically realizes a secure,

 recurring revenue stream for products, services and/or repairs for many years (sometimes decades) until the technology becomes outdated. Because the Company is often sole-sourced for developmental projects, it is highly unlikely that a competitor will replace such a designed-in product as the cost and re-qualification time to do so is prohibitive. These relationships enable us to narrow the field of competition considerably and grow based on repeat business with relatively low selling costs. As technology evolves, prime contractors may, over subsequent years, migrate to systems other than those we produce.

 Beyond the defense arena, initiatives to complete $42 billion in upgrades to the current National Railway System in the UK over the next three years while spending $115 billion over the next 10 years to build high speed rail to link London with the Midlands cities of Birmingham, Leeds and Manchester will generate significant opportunities for growth in demand for power electronics to upgrade and replace current infrastructure, both in rolling stock and track side controls. Relec's current relationships and track record for supplying power solutions to the UK rail industry position us ideally to capitalize on these ongoing refurbishment and expansion efforts. A similarly robust market in the medical power supply markets with a compound annual growth rate of 6.9% to reach $1.8 billion in 2025 creates growth opportunities for Relec in the UK. Increases in contracts for the precision manufacturing of medical diagnostic and calibration tools drive growth opportunities for Enertec as well.

 Our Business Strengths

 We have the following core strengths that we believe give us a competitive advantage:

 • Developing and producing classified military products requiring a Sensitive Compartmented Information Facility (SCIF) and personnel with appropriate security clearances. These products are designed-in to military systems such as fighter jets, military ships and vehicles.

 • Military grade quality (AS9100), ultra-reliable technology offerings with elegant designs and precision "high touch" manufacture that stand the test of time, narrow the field of competition and command enhanced operating margins.

 • Enduring relationships with "blue chip" customers in the defense market provide stable revenue growth and reduce sales cost.

 • Substantial growth in backlog of orders with definite delivery dates for solutions engineered into long life cycle platforms that provide revenue base for years to come. Global operations expand our market opportunities, extend our operational reach and diversify our business base.

 Our Strategy

 Our goal is to become the supplier of choice for the major players in the defense industry and provide for solutions for mission critical applications in health care.

 Our near-term strategies are focused on developing synergies as a result of the acquisition of Gresham Holdings:

 • Gresham Holdings incurred major overhead expenses being a subsidiary of a larger company. We incurred large expenses being a public company with very limited sales. We are combining the overhead functions, shrinking our leased facilities and focusing on cost reductions;

 • Consolidate duplicate functions and reduce the costs of sales, human resources, information technologies, quality management and contracts administration;

 • Combine the RF Solutions group into one subsidiary and reduce operating costs.

 In addition, we are focused on securing sufficient working capital to execute on a substantial backlog of orders with definite delivery dates, take on additional significant orders and further improve access to capital resources.

 Our long-term strategy includes the following key elements:

 • maintain, strengthen and expand relationships with current customers, by increasing on-time delivery, diversifying solutions offered and maximizing quality of solutions;

 • acquire designed-in products or companies. We believe there are many small well run, profitable defense contractors whose principal owner is nearing retirement which could be attractive acquisition targets;

 • attract new customers through building business development, marketing and sales infrastructure to raise market awareness and identify opportunities early in the design process;

 • take advantage of the cross-selling opportunities among our operating subsidiaries to leverage current resources;

 • enhance our geographic footprint by increasing marketing outreach, forming alliances with leading companies located in areas beyond its current reach and acquiring businesses that expand reach into other geographies.

 Our Operations

 We conduct our business through our subsidiaries. After the Business Combination, we aligned the operations of our subsidiaries into three key market groups as follows:

 Microphase focuses on designing, engineering, assembling, tuning and testing components, integrated assemblies and subsystems that detect, filter, analyze and process radio frequency, microwave and millimeter wave signals for defense applications.

 In the Precision Electronic Solutions group, Enertec, and the Giga-tronics Division and Microsource focus on designing, engineering, developing and producing turnkey precision electronic solutions for mission critical applications primarily focused on defense customers and large global healthcare customers.

 Power Electronics and Display Solutions

 Gresham Power focuses on providing power electronics solutions to defense customers in the UK and non-U.S. countries. Relec distributes power electronics and displays for mission critical applications to customers in health care, transportation, telecommunications and industrial businesses.

 A detailed description of three market groups and associated product offerings follows.

 Microphase Corporation

 Microphase designs, engineers, manufactures and distributes components, integrated assemblies and subsystems for a variety of military and telecommunications applications. Such components include RF and microwave filters, diplexers, multiplexers, detectors, switch filters, integrated assemblies and Detector Logarithmic Video Amplifiers. Microphase engineers, tunes and tests all its products under stress conditions per defined in tuning protocols and test procedures it developed as part of the production process. This approach ensures that its customers can use and incorporate Microphase products into systems with confidence that the products will perform reliably under extreme operating conditions.

 Microphase's customers include the U.S. military, and contractors to the U.S. military and to militaries of other countries including prime contractors and sub-contractors. Microphase's technology innovations are used in many significant U.S. Government defense programs, including the F-16, the F-18, the F-35, the JAS Gripen Fighter and the B-1B Bomber.

 Microphase's advanced technology products include:

 •

 filters that sort and clarify microwave signals, including multiplexers that are a series of filters combined in a single package;

 •

 solid state amplifiers that amplify microwave signals;

 •

 detectors and limiters that are semiconductor devices for detection of radar signals and protection of receivers from damage from high power signals and jamming;

 •

 detector log video amplifiers that are fully integrated, ruggedized, "mil-spec" signal detection systems; and

 •

 integrated assemblies that combine multiple functions from a range of components and devices, including transmitters, receivers, filters, amplifiers, detectors, and other functionality into single, efficient, high performance, multifunction assemblies.

 Microphase' revenue has grown 34% to $8.2 million in 2023 from $6.1 million in 2022.

 Enertec Systems 2001 Ltd.

 Based in Israel, Enertec designs, develops, manufactures and maintains advanced end-to-end high technology precision electronic solutions for military, medical and industrial markets. Those solutions include custom computer-based automated test equipment and turnkey systems to ensure combat readiness, provide command and control, and direct and deploy resources in military operations in harsh environments and battlefield conditions.

 Enertec delivers complete end-to-end project management with requirements definition, systems engineering, design/development, production, testing, integration, field support, maintenance and optimization. Its custom engineered solutions enable and support mission critical air, land and sea military platforms, e.g., missiles, UAVs, combat aircraft, boats, submarines, trailers and satellites. Enertec's primary customers include the largest major defense contractor in Israel. In addition, Enertec has a strategic partnership to build and deliver solutions for the Indian military.

 Enertec is among Israel's largest, most well-established manufacturers of test equipment and simulators. Enertec develops and manufacture test systems and simulators for all types of weapons systems at all levels of maintenance, development, and integration. Enertec is currently working on developing a new generation of electronics cards and assemblies to build a new generation of test systems. Enertec complies with all information security requirements included in its customer contracts as well as all the confidentiality laws that Israel mandates for work related to defense of the country.

 In addition, Enertec designs, develops, and provides precision equipment to calibrate cardiac catheters for a global health care products company. This business has grown to 27% of revenues in 2023 from 7% of Enertec's annual revenues in 2021. The US healthcare provider is very satisfied with the current product and is requesting an additional product design which the customer will pay for its development.

 Enertec's offices and engineering and assembly facility are located in Karmiel, Israel, which is near the border with Lebanon. The Hezbollah, an Iranian Proxy, who is located near the Lebanese border, threatens to expand the war to Northern Israel and is increasing its rocket attacks. As such, several employees had to relocate to a more southern location to avoid attacks from the north. In addition, several employees were drafted into military service.

 Enertec is a material subsidiary and through December 31, 2023, approximately 41% of the Company's revenues were derived from Enertec.

 The war in Israel poses significant risks to Enertec including possible rocket launches from Lebanon that could destroy Enertec's facility. Enertec has no alternative facility and the cost of locating a new facility and equipping it would effectively cause it to cease operations for at least six months. If the war continues, it could have a material adverse effect on our operations and financial condition.

 Enertec's revenue has grown approximately 24% in 2023 from $12.5 million in 2022.

 Giga-tronics Division

 Our Giga-tronics Division designs, manufactures, and markets functional test products and integrates those test products along with third-party hardware and software to deliver solutions for evaluating and validating radar and electronic warfare product performance. The Division developed a Threat Emulation System ("TEmS") using an agile, phase coherent wide bandwidth upconverter hosted within the compact industry standard AXIe modular platform. The TEmS solution is smaller in size, lower in cost than currently used threat simulation systems and when coupled with a tracking antenna, operates at lower power levels making it an ideal solution for outdoor installations with multiple locations for simulating integrated air defense systems.

 Giga-tronics Division's revenue has increased to $1.3 million in 2023 from $0.9 million in 2022. It currently has a $185,000 backlog.

 Microsource, Inc.

 Microsource's two largest customers are prime contractors for which we developed and manufactured sophisticated RADAR filters used in fighter aircraft. Microsource serves the market for operational hardware associated with the U.S. Government's RADAR Modernization Program for prior generation fighter aircraft (i.e., the F-15D, F-16, and F/A-18E jets) to extend their useful lives. We design these filters to operate under extreme conditions. Currently the platforms on which Microsource filter technologies are used are in various stages of product life cycle. Both F-15 and F-16 fighter jet fleets are aging out and programs are nearing end-of-life and are in maintenance and sustainment phases. This will result in reduced revenue

 As a result, revenue has declined to $2.7 million in 2023. The current backlog is $336,000.

 Power Electronics and Displays

 Our subsidiaries in the UK design, develop, manufacture and distribute advanced electronic technology solutions which convert, regulate, purify, manage or distribute electrical power for electronic equipment. Our power solutions are intended for mission-critical defense, industrial, health care and transportation applications in, and generally convert Alternating Current ("AC") from the power grid to Direct Current ("DC"), or

 modify the voltage being delivered (DC to DC). Our subsidiaries also offer standard off-the-shelf, modified-standard and purpose-built products. Although our subsidiaries sell standard products unmodified to its customers, those standard offerings are designed into specific customer product configurations in most instances. Our Power Electronics and Displays Group also designs, engineers and builds power systems and display solutions to specific customer requirements for mission critical applications in defense, medicine, transportation, telecommunications and manufacturing.

 Relec

 Relec develops custom, designed-in solutions for various applications ranging from light industrial to heavily ruggedized for the harshest of environments. Relec customizes product features and functionality to achieve optimum performance and service delivery for specific customer requirements. Relec currently operates in specific fields, specializing in AC-DC Power Supplies, DC-DC Converters, Displays and EMC Filters.

 Relec's revenue has grown 3% to $8.5 million in 2023 from $8.2 million in 2022.

 Gresham Power

 Gresham Power specializes in engineering, designing and developing power conversion, power supplies, uninterruptible power supplies and distribution solutions for Naval applications, with equipment installed on virtually all the UK Royal Navy's submarine and surface fleet. Many of Gresham Power's ultra-reliable offerings support shipboard distribution of electrical power in emergencies (such as loss of main ship's power) to enable continued operation of weapons systems, tactical communications and lighting.

 Gresham Power products add diversity to Gresham's product line, provide greater access to defense customers in the UK and European markets, and strengthen Gresham's engineering and technical resources.

 Gresham Power's revenue has declined 10% to $1.7 million in 2023 from $1.9 million in 2022.

 Research and Development

 In 2023, the research and development expenditures were approximately $2,827,000 or 7.4% of revenue. In 2022, the research and development expenditures were approximately $2,137,000 or 7.1% of revenue.

 We are focusing our development effort on military products which require (1) the handling of classified documents and an infrastructure that is secure such as a SPIC, CMMC and ITAR compliance, and (2) personnel that has security clearance and (3) meeting the military AS9100 quality standard. In addition, we are focused on products that are getting designed in to military systems such as fighter jet, ships and ground vehicles or missiles, which provide a recurring revenue stream for years to come and eliminate competition because the cost of replacing designed in products is prohibitive for both the competition and the customer.

 Our engineering and product development efforts vary with each operating subsidiary. Most of these efforts focus on designing and developing new products in connection with custom product design and modification of standard electronics offerings to provide solutions tailored to specific customer requirements. Our engineers work closely with customers and specialist partners to incorporate modifications or create custom designs for specific project requirements. The customer typically pays for such engineering services which are charged to the cost of revenue.

 Enertec provides full-service design and development of turnkey Precision Electronic Solutions. Microphase designs custom RF solutions to meet customer unique specifications. When required, other subsidiaries modify standard products to meet specific customer requirements, including, but not limited to, redesigning commercial products to meet requirements for military applications based on commercial off-the-shelf products and for other customized product requirements, when applicable. We continually seek to improve our product offerings while anticipating changing market demands for increased functionality, customized firmware and improved EMI (electromagnetic interference) filtering.

 The legacy Giga-tronics Division historically has funded product development activities internally, through product line sales, or through outside equity investment and debt financing. Microsource and Microphase typically have designed, engineered and developed new product offerings in close collaboration with and funded by its customers.

 There can be no assurance that future technologies, processes, or product developments will not render our current product offerings obsolete or that we will be able to develop and introduce new products or enhancements to existing products that satisfy customer needs in a timely manner or achieve market acceptance. Failure to do so could adversely affect our business.

 Competition

 The defense electronic technology solutions industry is highly fragmented and characterized by intense competition. Our competition includes thousands of companies located throughout the world, some of which have advantages in terms of labor and component costs, and some of which may offer products superior or comparable in quality to us. Each operating subsidiary confronts a different set of competitors depending on solutions offered, vertical markets targeted and geographic scope of operations. We also face competition from current and prospective customers who may decide to design and manufacture power electronics, communications components and precision electronic solutions needed to satisfy their internal programmatic requirements.

 Consolidation in the defense technology solutions market, including through mergers, acquisitions and/or strategic alliances among major primes to whom we sell our products, has the potential to intensify the competitive pressures that we face. Many of our existing and potential competitors may be better positioned than us to acquire other companies, technologies or products. We compete favorably on the basis of multiple factors, including product quality and reliability, technological capabilities, service, past performance, design flexibility and ability to develop and implement complex, integrated solutions customized to its customers' needs, and cost-effectiveness. Focusing on products with relatively low volumes and high margins enables our operating subsidiaries to compete favorably on price against larger companies with much high indirect cost structures (overhead and G&A) and cumbersome internal bureaucracies. Finally, the fragmentation of the defense technology market also creates opportunities to grow through acquiring competitors and/or potential competitors.

 Many competitors have substantially greater financial and marketing resources and geographic presence than we have. However, cost-effective designs, elegant engineering, a collaborative/consultative approach to managing customer relations and a long history of delivering high quality, ultra-reliable, custom designed components and subsystems have enabled us to compete effectively and carve out a defensible niche position against competitors with more resources.

 Manufacturing and Testing

 We fabricate components and performs product assembly, integration and testing at production facilities in Livermore, California (Microsource and the Giga-tronics Division), Shelton, Connecticut (Microphase), Karmiel, Israel (Enertec) and Salisbury, England (Gresham Power). Each of our operating business has built a robust network of trusted supply chain partners to provide components, materials and parts for assembly into products or products for resale.

 We continually strive to improve our production and test processes, to ensure the highest quality and consistent manufacturing of its solutions. Each operating business maintains rigorous quality control to ensure that our solutions conform to all customer specifications and will perform reliably in the customer's application. We test our products under stress operating conditions per defined test procedures we developed in conjunction with our customers. This approach ensures that our customers can use its solutions right out of the box on their production line or installed directly in the field. We offer customer specific testing services with custom designed tests to simulate operation within our customer applications.

 All operating units comply with all applicable safety and EMC standards for electronics solutions.

 Compliance with international safety agency standards is critical in every application, and power solutions play a major role in meeting these compliance requirements. Our safety engineers and quality assurance teams help ensure that our custom products are designed to meet all safety requirements and are appropriately documented to expedite safety approval processes.

 We maintain ISO 9001:2008 (Enertec), ISO 9001:2015 (Microphase, Gresham Power and Relec) and AS9100D (Enertec, Microphase, Microsource and the Giga-tronics Division) certification in our manufacturing operations. ISO 9001 and AS9100 are universally recognized and accepted international standards for quality management.

 Customer Service and Support

 Our operating companies offer a "high touch" approach to optimizing and customizing solution offerings to meet customer unique requirements. Working closely with customers, we design, engineer, develop and produce offerings to the highest standards of performance, durability and reliability to meet unique customer requirements. All operating units constantly track performance against cost, quality and on-time delivery metrics with an intense focus on customer satisfaction. Following the Business Combination, regular communications and direct collaboration at all levels with customers have become hallmarks of all our operations.

 Given the mission critical nature of the customer applications which our product and solution offerings support, we respond promptly and take necessary corrective action to ensure our offerings conform to the specifications and work to that specific customer's expectations. We provide warranties on all products offered. The length and terms of the warranties vary with the product type and application in which the product gets used. In addition, even after warranties expire, our operating units will provide maintenance, repair and post-delivery support for the full expected life of the product.

 Suppliers

 Given the demanding performance requirements and challenging operating envelopes for Gresham products and the Platforms on which they're used, component vendor selection and management is a key success factor. While substantially most of the components required to make our assemblies are available from multiple sources, we occasionally use sole source arrangements to obtain leading-edge technology or favorable pricing or supply terms, but not in any material volume. Furthermore, the longevity of the programs on which our products are used occasionally presents a parts obsolescence challenge which the Company is continuously monitoring and managing. In our opinion, the loss of any sole source arrangement we have would not materially affect our operations, though we could experience production delays as we seek new suppliers or re-design components of our products. Some suppliers are also competitors of ours. In the event a competitor-supplier chooses not to sell its products to us, production delays that could significantly affect our business could occur as we seek new suppliers or re-design components of our products.

 Our operating businesses purchase electronic components, materials, parts and assemblies, including power supplies, converters, transformers, rectifiers, inverters, housings, blocks, covers, machined parts, substrates, resistors, diodes, detectors, amplifiers, integrated circuits, printed circuit

 boards, cables, connectors, metal work, and capacitors, from outside suppliers. We also purchase certain precious metals used in manufacturing of our products (plating, sealing, painting, finishing). We carefully select suppliers based on their ability to provide quality parts and components which meet technical specifications and volume requirements. For defense work, our subsidiaries have built supply chain networks from sources only in the U.S. (Microphase and Microsource source exclusively from the U.S.), Enertec and Relec also source from the U.S., the UK (Gresham Power, Relec) and Israel (Enertec) with no sourcing from China. Relec does work with suppliers in China for some commercial applications.

 Customers

 Gresham's defense customers include the Israeli MOD and Israel Air Industries ("IAI"), Rafael and Elbit Systems, the four major defense contractors in Israel, the United States Department of Defense ("U.S. DOD") and major defense contractors such as BAE Systems North America, L3Harris, Boeing, Lockheed Martin, Raytheon and Sierra Nevada Corporation in the U.S., the UK Ministry of Defense including the Royal Navy, and major defense contractors in the UK and Europe, including BAE Systems PLC, Rolls Royce, Babcock and Thales, SAAB (Sweden), Indra (Spain) and Aselsan (Turkey). In addition, Enertec has a strategic partnership through IAI with Cyient to build and deliver solutions for the Indian military.

 Gresham's commercial customers include Elma GmbH, BioSense Webster, a subsidiary of Johnson & Johnson (a key Enertec customer), RS Components, Farnell, Parker Hannifin, Vanderbilt, Bombardier.

 For 2023, Gresham's two largest customers accounted in the aggregate for 40% of its consolidated revenues. The following table describes Gresham's customer concentration as of December 31, 2023, based on the percentage of revenue during 2023:

 Our business depends largely on defense spending and program budgets which expand and contract across fiscal year periods. Revenues from orders for our products and services often span several years with deliveries varying across both interim and annual fiscal year periods. We therefore expect that a major customer in one year may not be a major customer in the following year. Accordingly, our net revenue and earnings may vary significantly from one period to the next and will decline if we are unable to gain new customers or cannot increase our business with other existing customers to replace declining net revenue from the previous year's major customers.

 Proprietary Technology and Intellectual Property

 Our competitive position is largely dependent upon our ability to deliver systems and products that (a) effectively and reliably meet customers' needs and (b) selectively surpass competitors' specifications in competing products. While patents may provide protection of proprietary designs, with the rapid progress of technological development in our industry, such protection is often short-lived. Therefore, although we occasionally pursue patent coverage, we emphasize the development of new products with superior performance specifications and the upgrading of existing products toward this same end.

 Our trade names, trademarks, trade secrets, customer relationships, domain names, proprietary technologies and similar intellectual property are important to our success. We rely upon a combination of trade secrets, industry expertise, confidential procedures, and contractual provisions to protect our intellectual property. We believe that because our products are continually updated and revised, obtaining patents would be costly and not beneficial. It is policy to enter into confidentiality and invention assignment agreements with our employees and contractors as well as nondisclosure agreements with our suppliers and strategic partners in order to limit access to and disclosure of our proprietary information.

 Microphase and Enertec typically design custom products to their customer specifications as "work for hire" and therefore own no intellectual property in the design. As the ultimate end user, the U.S. military and the Israeli MOD typically acquire and retain rights in all such technical data. Microphase does acquire and own intellectual property in the fabrication, assembly, tuning and testing protocols followed for its products.

 In the UK, Gresham Power typically will retain ownership of the intellectual property of the designs of products developed for defense applications. However, neither Relec nor Gresham Power typically retain intellectual property in any of the standard power products that they sell on the commercial market.

 Our Giga-tronics Division products are primarily based on our own designs, which are derived from our own engineering abilities. If our new product engineering efforts fall behind, our competitive position weakens. Conversely, effective product development greatly enhances our competitive status. While we utilize certain software licenses in certain functional aspects for some of our products, such licenses are generally readily available, non-exclusive and are obtained at either no cost or for a relatively small fee.

 We have maintained three patents related to our 2500B parametric signal generator and two patents related to the Company's Advanced Signal Generator & Analysis product lines (ASGA platform). A third patent for the ASGA platform was recently granted.

 In February 2020, the Company was granted a U.S. patent relating to its ASGA Platform. The patent describes the internal design of the Advanced Signal Generator and the Advanced Signal Analyzer ("ASGA") along with the architecture of how the components work together to facilitate building multi-channel test systems with reduced size, weight and cost as compared to present solutions. A second patent was granted in

 November 2020 describing uses of the ASGA system in high channel-count situations. A third patent application which was filed in April 2020 describing how the ASGA platform achieves its low noise performance while achieving fast frequency switching speeds was granted by the U.S. Patent and Trademark Office on May 30, 2023.

 The Company has paid the U.S. Patent and Trademark Office fees to keep the patents open to allow adding new claims as they arise for continued intellectual property protection.

 Operating Capital

 We generally strive to maintain adequate levels of inventory and we generally sell to customers on 30-day payment terms in the U.S while allowing more time for our international customers. Typically, we receive payment terms of 30 days from our suppliers. We believe that these practices are consistent with typical industry practices. Beyond financing, our primary sources of liquidity come from customer sales, which are dependent on our receipt and shipment of customer orders.

 Gresham's liquidity was historically supported by AAI's injection of cash consisting of contributions to capital and loans. AAI has continued to support us with $2.4 million of loans in fiscal 2023. We are seeking additional capital to fund our operations, although we may not be successful in our efforts to do so. See "Risk Factors - Risks Related to Our Financial Condition". We will need additional capital to fund our operations, and our inability to generate or obtain such capital on acceptable terms, or at all, could harm our business, operating results, financial condition and prospects."

 See "Management's Discussion and Analysis of Financial Condition and Results of Operations -Liquidity and Capital Resources - Our Recent Financings" for the discussion of our financing activities.

 Sales and Marketing

 We market our products directly to our customers and rely on internal sales forces within each of our operating subsidiaries primarily to identify leads and complete sales. We also engage independent sales representatives who are perceived to have expertise with targeted markets and/or customers. Our marketing and sales efforts target specific types of customers such as major defense contractors, manufacturers of industrial products, health care solutions and infrastructure components in transportation and telecommunications.

 Corporate Chief Development Officer

 Following the Business Combination, we began relying on Gresham Holdings then Chief Operating Officer to lead our sales and marketing team. Prior to that executive's retirement in November 2023, he had recruited our Chief Development Officer whose principal role is to drive organic growth and identify prospects for further growth through mergers and/or acquisitions. We have implemented Gresham's Hub Spot to capture and track the opportunity stream within and among the operating subsidiaries.

 In recent years, much of the business development effort at Microphase comes through engineer to engineer collaboration resulting into products that are designed-in to military systems, as well as our Chief Development Officer holding and maintaining most customer relationships. For the foreseeable future, the backlog of designed-in products is driving the RF Solutions business.

 Much of business development and sales effort at Enertec has historically taken place at the senior executive level. The two largest customers of Enertec resulted in 98% of Enertec's revenue in 2023. Enertec's former Chief Executive Officer passed away in early March 2024. Our Chief Operating Officer Mr. Nissim Ovadia worked closely with Mr. Avni and has been promoted to Chief Executive Officer at Enertec. Mr. Ovadia while Chief Operating Officer was able to interface with Enertec's key customers. Additionally, our Chief Executive Officer, Mr. Jonathan Read is the new Chairman of Enertec and is focusing additional efforts to its business. Going forward, we are hopeful that our Precision Electronic Solutions will benefit from Mr. Ovadia's continuing effort to develop business for turnkey precision electronic solutions.

 Power Electronics and Displays

 The Power Electronics and Displays group has a high performing team of four sales professionals supported by a sales administrator and two inside sales professionals to continue drive new business and growth in the UK and European markets. If we can solve our liquidity issues, we plan to add more business development resources in 2024 focused specifically on defense customers for Power Electronics and Displays while the group also expands use of strategic third-party channel partners and or Manufacturer's Representatives in the Middle East, India and Australia in 2024. These representatives will promote our products and serve as the customer interface for Power Electronics and Displays in specific parts of the world as agreed. Typically, either we or the manufacturing representatives are entitled to terminate the manufacturer representative agreement upon 30 days' written notice.

 Relec and Gresham Power advertise in highly targeted industry-specific publications such as Electronics Weekly, New Electronics, Electronic Product Design & Test, Electronics Specifier, Components in Electronics, Design Products & Applications, Rail Technology Magazine, Rail Engineer, Rail Professional. In addition, Relec also posts regular podcasts on topics of interest to customers and prospect as well as running an active public relations campaign to get placements of earned media and coverage in a wide range of media. We look to replicate similar campaigns in other operating subsidiaries to generate inquiries/leads, raise awareness of us and support talent recruiting efforts.

 Other Marketing Activities

 We promote our products and solutions by attending trade shows such as the Association of Old Crows Conferences, Defense Manufacturing Conference, Land Forces Conference (Australia), Doha International Maritime Defense Exhibition & Conference (DIMDEX) Electronica (Europe), Southern Manufacturing and Electronics, and Railtex.

 Each of our operating businesses maintain a comprehensive website emphasizing its respective capabilities and expertise. We plan to upgrade all our websites to standardize corporate identification while adding more features and functionality to drive inquiries, generate leads from prospective customers and support recruiting efforts.

 Government Regulation

 We must meet applicable regulatory, environmental, emissions, safety and other requirements where specified by the customer and accepted by it or as required by local regulatory or legal requirements. The products that we market and sell in Europe may be subject to the 2003 European Directive on Restriction of Hazardous Substances ("RoHS"), which restricts the use of six hazardous materials in the manufacture of certain electronic and electrical equipment, as well as the 2002 European Directive on Waste Electrical and Electronic Equipment ("WEEE"), which determines collection, recycling and recovery goals for electrical goods. In July 2006, our industry began phasing in RoHS and WEEE requirements in most geographical markets with specific emphasis on consumer-based products. We believe that RoHS and WEEE-compliant components may be subject to longer lead-times and higher prices as the industry transitions to these new requirements. REACH Registration, Evaluation, Authorization and Restriction of Chemicals Registration, is a European Union regulation dating from December 18, 2006. REACH addresses the production and use of chemical substances, and their potential impacts on both human health and the environment.

 In addition to these requirements for our dealings with customers in the EU, similar regulatory mandates from the U.S., the UK and Israel apply to all our operating subsidiaries. We have structured operations to comply with these requirements and have experienced little to no impact on lead times or prices. Given the applicability of these requirements to all competitors alike, we believe that compliance has had no impact on the competitive position of any operating subsidiary.

 Some of our products are subject to the International Traffic in Arms Regulation ("ITAR"), which is administered by the U.S. Department of State. ITAR controls not only the export of certain products specifically designed, modified, configured or adapted for military systems, but also the export of related technical data and defense services and foreign production. We obtain required export licenses for any exports subject to ITAR. Compliance with ITAR may require a prolonged period of time; if the process of obtaining required export licenses for products subject to ITAR is delayed, it could have a materially adverse effect on our business, financial condition, and operating results. Any future restrictions or charges may be imposed by the U.S. or any other foreign country. In addition, from time-to-time, we enter into defense contracts to supply technology and products to foreign countries for programs that are funded and governed by the U.S. Foreign Military Financing program.

 We are also subject to heightened government scrutiny of our operations pursuant to certain of our contracts.

 Security Clearances

 As a U.S. Government contractor, we are required to maintain facility and personnel security clearances complying with the U.S. DOD and other Federal agency requirements. All Gresham operating companies in the U.S. maintain strict protocols for handling classified information and Confidential Unclassified Information associated with its work for the U.S. DOD. We have built within both our production facilities in Shelton, CT and Livermore, CA "Restricted Areas" certified for generating, storing and reviewing classified information. Our U.S. subsidiaries and Division also must obtain and maintain "authority to operate" equipment to perform classified work. The process to secure these authorities is long and laborious. Our U.S. subsidiaries have an experienced information security team to oversee applications to secure these authorities as well as ongoing monitoring to maintain the security of these systems.

 Gresham Power works on contracts classified as "Official Sensitive" that require individual security clearances and adherence to information security protocols for receiving, handling and storing confidential information as required in the UK Official Secrets Act and its implementing regulations. Relec does not work on classified, sensitive defense work.

 Enertec complies with all information security requirements included in its customer contracts as well as all the confidentiality laws that the State of Israel mandates for work related to defense of the country.

 Audits and Investigations

 As a government contractor, we are subject to audits and investigations by U.S. Government agencies including the Defense Contract Audit Agency (the "DCAA"), the Defense Contract Management Agency (the "DCMA"), the Inspector General of the U.S. DOD and other departments and agencies, the Government Accountability Office, the Department of Justice (the "DoJ") and Congressional Committees. From time-to-time, these and other agencies investigate or conduct audits to determine whether a contractor's operations are being conducted in accordance with applicable requirements. The DCAA and DCMA also review the adequacy of, and compliance with, a contractor's internal control systems and policies, including the contractor's accounting, purchasing, property, estimating, earned value management and material management accounting systems. Our final allowable incurred costs for each year are also subject to audit and have from time to time resulted in disputes between us and the U.S. Government. Any costs found to be improperly allocated to a specific contract will not be reimbursed or must be refunded if already reimbursed. If an audit or investigation uncovers improper or illegal activities, we may be subject to civil and criminal penalties and administrative

 sanctions, which may include termination of contracts, forfeiture of profits, suspension of payments, fines and suspension or prohibition from doing business with the U.S. Government.

 The Defense Federal Acquisition Regulation, as implemented in standard contract clauses, mandates that our U.S. business establish and follow extensive detailed processes and protocols to protect classified and Confidential Unclassified Information (CUI) from disclosure and unauthorized access. That mandate includes a requirement that Microphase formulate and implement a System Security Plan with 110 different elements and protocols for handling and protecting classified information and CUI. Over the next two years the U.S. DOD will require all participants in the defense supply chain to demonstrate compliance with the Capability Model Maturity Cybersecurity as verified through an independent third-party auditor. Compliance with these mandates requires and will require Gresham's U.S. subsidiaries to invest significant resources to maintain compliance. For instance, compliance requires extensive security controls on access to IT systems, strong firewalls and intrusion monitoring. We have in place an experienced team to ensure information security for all subsidiaries in the U.S. as well as oversee security of all employees and facilities in U.S. operations. These investments add to indirect cost pools that our U.S. operations must recover in the price of its products for U.S. DOD and contractors.

 Enertec conducts operations under constant supervision of the Ministry of Defense of Israel. All its contracts are subject to audits of performance, quality and price reasonableness. Enertec has implemented the strongest possible cybersecurity protections consistent with the resources available to a company its size.

 Gresham Power contracts with UK Ministry of Defense, Royal Navy or major contractors serving those agencies include standard provisions which give the customer the right to audit its performance under those contracts when they see fit. Audits are part of doing business with the government and typically focus on deliveries - on time project milestones as well as quality. The Royal Navy reviews Gresham Power pricing of services provided under support contract every 12 months for reasonableness.

 Gresham Power is fully certified as "Cyber Essentials Plus Compliant." Cyber Essentials Plus is a government backed, industry-supported scheme to help organizations protect themselves against common online threats. The UK Government requires all suppliers bidding for contracts involving the handling of sensitive and personal information to be certified against the Cyber Essentials program criteria.

 Other Compliance Issues

 In addition, we are subject to the local, state and national laws and regulations of the jurisdictions where we operate that affect companies generally, including laws and regulations governing commerce, intellectual property, trade, health and safety, the environment contracts, privacy and communications, cybersecurity, web services, tax, and corporate laws and securities laws. These regulations and laws may change over time. Unfavorable changes in existing and new laws and regulations could increase our cost of doing business and impede its growth.

 Employees

 As of April 15, 2024, we had a total of 179 employees located in the U.S., the UK and Israel. All but seven of these employees are employed on a full-time basis. We believe that our future success depends on our ability to attract and retain skilled personnel. Competition for skilled personnel in our markets is competitive. While our size and capital resources constrain our ability to attract and retain employees with cash compensation, we attempt to compensate for this constraint by offering opportunities for training and internal promotion. None of our employees is currently represented by a trade union. We consider our relations with our employees to be good. From time-to-time, we may hire additional workers on an independent contractor basis as the need arises. Presently, due to its backlog and expected orders, Microphase needs to add employees in addition to its planned use of Microsource employees.

 ITEM 1A. RISK FACTORS

 An investment in our common stock involves significant risks. Before investing in our common stock, you should consider each of the following risk factors and any other information set forth in this Report and the other reports filed by the Company with the Securities and Exchange Commission (the "SEC"),including the Company's financial statements and related notes, in evaluating the Company's business and prospects. The risks and uncertainties described below are not the only ones that impact on the Company's operations and business. Additional risks and uncertainties not presently known to the Company, or that the Company currently considers immaterial, may also impair its business or operations. If any of the following risks actually occurs, the Company's business and financial condition, results or prospects could be harmed. Please also read carefully the section entitled "Forward-Looking Statements" at the beginning of this Report. If any of the events or developments described below occurs, our business, financial condition and results of operations may suffer. In that case, the value of our common stock may decline and you could lose all or part of your investment.

 Risk Factors Summary

 Our business and an investment in our common stock are subject to numerous risks and uncertainties, including those highlighted in this "Risk Factors" section below. Some of these risks include:

 Risks related to our Financial Condition

 • We have doubts about our ability to continue as a going concern.

 • We have historically incurred net losses and negative cash flow and our operating results may significantly vary from quarter-to-quarter, so we may not be able to achieve or sustain profitability.

 • Because we require consents to obtain new financings, we may not be able to pursue these transactions if we cannot obtain the consents.

 • As a result of our outstanding convertible notes and related warrants, our stockholders are subject to significant future dilution.

 Economic, Policy and Business Risks

 • A large percentage of our current revenue is derived from prime defense contractors to the U.S. government and its allies, and the loss of these relationships, a reduction in government funding or a change in government spending priorities or bidding processes could have an adverse impact on our business, financial condition, results of operations and cash flows.

 • If our reputation or relationships with the governments of the U.S., the UK or Israel or the limited number of defense contractors with whom we work were harmed, our future revenues and cash flows would be adversely affected.

 • Because we engage in fixed fee contracts with our customers, we face pressure on our gross profit margins and operating costs from inflation.

 • The effects of Russia's invasion of Ukraine, the war in Israel and tensions elsewhere in the world on the capital markets and the economy is uncertain, and we may have to deal with a recessionary economy and economic uncertainty including possible adverse effects upon the capital markets.

 • We must replace the former Chief Executive Officer of Gresham Power and hire a new Chief Financial Officer for Enertec.

 • If the inflationary pressures in the US. and elsewhere where we operate continue, we could experience reduced margins and lose future business.

 Sales, Business Development and Competitive Risks

 • Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, our sales and revenue are difficult to predict and may vary substantially from period to period, which may cause our operating results to fluctuate significantly.

 • Our sales are significantly dependent on the defense industry and a limited number of customers.

 • We face intense industry competition and product obsolescence, which, in turn, could increase our losses.

 • If we are unable to monetize our legacy Giga-tronics business, we may be required to discontinue its business.

 Performance and Operational Risks

 • If we are unable to identify, attract, train and retain qualified personnel, especially our design and technical personnel, our business and results of operations would be materially and adversely affected and we may not be able to effectively execute our business strategy.

 • Performance problems in our products or problems arising from the use of our products together with other vendors' products may harm our business and reputation.

 • Supply chain disruptions and our inability to procure necessary component parts for our products have materially and adversely affected our results of operations and could materially and adversely affect our results of operations in the future.

 • We may not be able to procure necessary key components for our products, or we may purchase too much inventory.

 • We depend on a limited number of major customers for a significant portion of our revenue. The loss of any of these customers, or the substantial reduction in the quantity of products that they purchase from us, would materially adversely affect our business and results of operations.

 Risks Related to our Foreign Operations

 • Because we have a material subsidiary that operates in Israel, the war which began October 7, 2023 may have a material adverse effect on our future results of operations and financial condition.

 • Many of Enertec's employees are obligated to perform military reserve duty in Israel, which could have a disruptive impact on our business.

 • We depend on international sales for a material portion of our revenue.

 • A material portion of our revenue and expenses is denominated in foreign currencies, so fluctuations in exchange rates could have a material adverse effect on our operating results.

 Regulatory and Compliance Risks

 • Our businesses are subject to government procurement laws and regulations.

 • If we fail to comply with anti-bribery, anti-corruption, anti-money laundering laws, and similar laws, or allegations of such failure, it could have a material adverse effect on our business, financial condition and operating results.

 • If we fail to comply with the rules under the Sarbanes-Oxley Act of 2002 related to accounting controls and procedures, or if we discover additional material weaknesses and deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult.

 Risks Related to the Ownership of our Common Stock

 • Because of limited volume of our common stock, you may not be able to sell many shares without depressing the price.

 • Our stock price may be volatile, which could result in substantial losses to investors and litigation.

 • The rights of the holders of common stock may be impaired by the potential additional issuance of preferred stock.

 • Because our shares of common stock are subject to the penny stock rules, it is more difficult to buy our shares.

 • We do not anticipate paying any dividends on our common stock for the foreseeable future.

 Risks Related to our Financial Condition

 We have doubts about our ability to continue as a going concern.

 We believe that there is doubt about our ability to continue as a going concern because we have incurred recurring net losses and we have not been able to procure funding for our negative cashflows. Convertible notes issued to two lenders mature in October 2024 and convertible notes issued to AAI mature in January 2025. Our inability to continue as a going concern could have a negative impact on the Company, including our ability to obtain needed financing, and could adversely affect the trading price of our common stock.

 We have historically incurred net losses and negative cash flow and our operating results may significantly vary from quarter-to-quarter, so we may not be able to achieve or sustain profitability.

 For the years ended December 31, 2023 and 2022, Gresham reported revenue of $38.0 million and $30.3 and net losses of $15.3 million and $18.4 million, respectively. We expect to continue to incur substantial expenditures to develop and market our products and services and we could continue to incur losses and negative operating cash flow in the near future. As the result of our lack of working capital, we face a number of challenges:

 • We have been unable to make installment payments to an investment banker we hired to re-finance our indebtedness. As a result, this party will not provide any further services;

 • Other service providers have not been paid and have cut back or no longer provide services;

 • We owe senior management $112,000 in back salaries and $11,000 on credit cards; and

 • We owe our Chief Financial Officer $50,000 due to our inability to repay interim the loan he made last year. We also owe our Audit Committee Chairman $74,500 in accrued fees which AAI has agreed to pay over time.

 In addition, our operating results have in the past been subject to quarter-to-quarter fluctuations, and we expect that these fluctuations will continue, and may increase in magnitude, in future periods. Demand for our products is driven by many factors, including the availability of funding for our products in our customers' budgets. There is a trend for some of our customers to place large orders near the end of a quarter or fiscal year, in part to spend remaining available budget funds. Seasonal fluctuations in customer demand for our products driven by budgetary and other concerns can create corresponding fluctuations in period-to-period revenue, and we therefore cannot assure you that our results in one period are necessarily indicative of our revenue in any future period. In addition, the number and timing of large individual sales and the ability to obtain acceptances of those sales, where applicable, have been difficult for us to predict, and large individual sales have, in some cases, occurred in quarters subsequent to those we anticipated, or have not occurred at all. The loss or deferral of one or more significant sales in a quarter could harm our operating results for such quarter. It is possible that, in some quarters, our operating results will be below the expectations of public market analysts or investors. Finally, supply chain issues have in the past and may in the future affect future quarters.

 We will need additional capital to fund our operations, and our inability to generate or obtain such capital on acceptable terms, or at all, could harm our business, operating results, financial condition and prospects.

 We will need to raise additional capital to pay our indebtedness and to support our working capital requirements and our planned growth. Any other future financing may include shares of common stock, shares of preferred stock, warrants to purchase shares of common stock or preferred stock, debt securities, units consisting of the foregoing securities, equity investments from strategic development partners or some combination of the foregoing. There is no assurance that additional financing will be available, or if available, will be on acceptable terms. If we are unable to raise additional capital, we may be required to curtail our operations and take additional measures to reduce costs, including reducing our workforce and eliminating outside consultants in order to conserve cash in amounts sufficient to sustain operations and meet our obligations. This could in its turn have a material adverse effect on our business, operating results and future prospects. There can be no assurance that we will be able to complete any future financing.

 Because we require consents to obtain new financings, we may not be able to pursue these transactions if we cannot obtain the consents.

 We issued AAI Series F preferred stock and common stock upon the consummation of the Business Combination. The term of the Series F contains negative covenants that apply such as incurring indebtedness of $1,000,000 in any individual transaction or $2,500,000 in the aggregate, or acquiring any business in which the aggregate consideration payable by us is $1 million or more. In addition, if we issue further equity, subject to exceptions for certain excluded securities, such limited issuances pursuant to equity incentive plans, AAI will have the right to purchase additional equity to maintain its ownership interest. Even if AAI fully converts the Series F into shares of our common stock, the Convertible Notes that we issued in connection with the AAI Financing and the transaction documents that we entered into in connection with our January 2023 sale of Senior Secured Convertible Notes with the two investment funds contain substantially similar covenants that are included in the Series F. These provisions could limit our ability to raise capital or make future acquisitions, particularly larger acquisitions. For more information about these negative covenants, see "Management's Discussion and Analysis of Financial Condition and Results of Operations - Liquidity and Capital Resources – Our Financings."

 As a result of our outstanding convertible notes and related warrants, our stockholders are subject to significant future dilution.

 As of April 8, 2024 we had $18.2 million in outstanding indebtedness evidenced by convertible notes which are convertible into 72.9 million shares of our common stock, subject to possible increases, and 2 million warrants exercisable for nominal consideration. Because of our cash needs, we will have to engage in a new financing or modify of our existing financings. Any new financing or modification may be even further dilutive to our stockholders. Further, the convertible notes have price protection so if we enter into a new financing with a lower conversion or exercise price, those instruments will automatically be adjusted resulting in further dilution.

 Economic, Policy and Business Risks

 A large percentage of our current revenue is derived from prime defense contractors to the U.S. government and its allies, and the loss of these relationships, a reduction in government funding or a change in government spending priorities or bidding processes could have an adverse impact on our business, financial condition, results of operations and cash flows.

 The defense programs may compete with other policy needs, which may be viewed as more necessary. For example, budget and appropriations decisions made by the governments of the U.S, the UK and Israel are outside of our control and have long-term consequences for its business. Government spending priorities and levels remain uncertain and difficult to predict and are affected by numerous factors, and the purchase of our products could be superseded by alternate arrangements. The current prolonged delay in providing new aid to Ukraine and Israel are evidence of the political uncertainties. While defense budgets in countries around the world have generally increased, there can be no assurance that such increases will continue for the foreseeable future. A change in government spending priorities or an increase in non-procurement spending at the expense of our programs, or a reduction in total defense spending, could have material adverse consequences on our future business.

 If our reputation or relationships with the governments of the U.S., the UK or Israel or the limited number of defense contractors with whom we work were harmed, our future revenues and cash flows would be adversely affected.

 Gresham derives most of its revenue from the governments of the U.S., the UK and Israel as well defense contractors across the world that supply those countries and their allies. Our reputation and relationships with various government entities and agencies, in particular with the U.S. DOD and Ministries of Defense in the UK and Israel, and the limited number of defense contractors serving these agencies, are key factors in maintaining and growing these revenues and winning bids for new business. Negative press reports or publicity, regardless of accuracy, could harm our reputation. If our reputation or relationships with government agencies were to be negatively affected, or if we are suspended or debarred from contracting with government agencies for any reason, the amount of business with government and other customers would decrease and our financial condition and results of operations could be adversely affected.

 Because we engage in fixed fee contracts with our customers, we face pressure on our gross profit margins and operating costs from inflation.

 Our financial condition, results of operations, and liquidity may be negatively impacted by increased levels of inflation. We are not able to predict the timing and effect of inflation, or its duration and severity. Inflation may cause our costs to purchase inventory to be higher than we planned, and reduce our gross profit margins. Also inflation tends to increase our compensation and other costs. Because of the fixed price contracts we enter into,we may not be able to sell our products to our customers at correspondingly increased prices to cover the impact of inflation, resulting in decreased profit margins.

 We may have liabilities that are not known, probable or estimable at this time.

 We remain subject to certain past, current, and future liabilities. There could be unasserted claims or assessments against or affecting us, including the failure to comply with applicable laws and regulations. In addition, there may be liabilities of ours that are neither probable nor estimable at this time that may become probable or estimable in the future, including indemnification requests received from our customers relating to claims of infringement or misappropriation of third party intellectual property or other proprietary rights, tax liabilities arising in connection with ongoing or future tax audits and liabilities in connection with other past, current and future legal claims and litigation. Any such liabilities, individually or in the aggregate, could have a material adverse effect on our financial condition. We may learn additional information that adversely affects us, such as unknown, unasserted, or contingent liabilities and issues relating to compliance with applicable laws or infringement or misappropriation of third-party intellectual property or other proprietary rights.

 The effects of Russia's invasion of Ukraine, the war in Israel and tensions elsewhere in the world on the capital markets and the economy is uncertain, and we may have to deal with a recessionary economy and economic uncertainty including possible adverse effects upon the capital markets.

 Russia's invasion of Ukraine, the war in Israel and tensions with China and Iran have created increased uncertainty in the capital markets and caused in part increased inflation. This may make it more difficult for us to raise capital and the result may be more expense and dilution. We cannot predict how these factors will affect the capital markets, but the impact may be adverse and may delay or prevent us from completing future financings or make any financings.

 If the inflationary pressures in the U.S. and elsewhere where we operate continue, we could experience reduced margins and lose future business.

 While the inflation rate is lower than it had been, the current inflationary pressures are affecting our gross profit margins particularly since we have lacked the capital to accumulate material inventory. Most of our contracts (except with Relec) are fixed price, which reduces our margins when inflation occurs. Reducing our selling prices results in further reduction of our margins. This customer pricing pressure may also result in the loss of contracts and/or future business. Finally, we are experiencing rising labor and other costs which may further increase our losses.

 If we lose key personnel, it could have a material adverse effect on our financial condition, results of operations, and growth prospects.

 Our success will depend on the continued contributions of key officers and employees. The loss of the services of key officers and employees, whether such loss is through resignation or other causes, or the inability to attract additional qualified personnel, could have a material adverse effect on our financial condition, results of operations, and growth prospects. In November 2023, our Chief Operating Officer retired. He was a key employee, and he is not being replaced as his duties have been assumed by our Chief Technology Officer. While we believe the replacement of Enertec's former Chief Executive Officer by its Chief Operating Officer will not have a material adverse effect, it is possible that our expectations will be proved to be incorrect. Further, Gresham Power's Chief Executive Officer passed away in March 2024. With Gresham Power, the loss of Ms. Karen Jay must be viewed against its declining business. We are uncertain whether we will be able to replace her.

 Our success will depend on the continued contributions of key officers and employees. The loss of the services of key officers and employees, whether such loss is through resignation or other causes, or the inability to attract additional qualified personnel, could have a material adverse effect on our financial condition, results of operations, and growth prospects. In November 2023, our Chief Operating Officer retired. He was a key employee, and he is not being replaced as his duties have been assumed by our Chief Technology Officer. The loss of Zvika Avni, Enertec's Chief executive Officer, due to illness who managed our Israeli operations in the past, could also materially harm our business.

 We do not know if the loss of key employees will result in any adverse effects. However, if we were to lose Jonathan Read, Robin Shaffer, Sean Lyle and/or Lutz Henckels, our Chief Executive Officer, Chief Operating Officer, Chief Development Officer and Chief Financial Officer respectively, or Nissim Ovadia, Enertec's Chief Executive Officer, our business would be materially and adversely affected.

 Our sales and profitability may be affected by changes in economic, business and industry conditions.

 If the economic climate in the U.S. or abroad deteriorates, customers or potential customers could reduce or delay their orders. In this regard, it was reported in February 2024 that the UK, where we have two subsidiaries, has entered a recession. In this environment, our customers may experience financial difficulty, reduce operations and fail to budget or reduce budgets for the purchase of our products. This may lead to longer sales cycles, delays in purchase decisions, payment and collection, and can also result in downward price pressures, causing our sales and profitability to decline. In addition, general economic uncertainty and general declines in capital spending in the defense electronics sector make it difficult to predict changes in the purchasing requirements of our customers and the markets we serve. There are many other factors which could affect our business, including:

 • Political factors, which result in a reduction of defense expenditures;

 • The end of the Russian war in Ukraine, the end of the war in Israel, stability in the Middle East or easing of tensions in Asia;

 • Gas shortages and environmental issues which divert defense expenditures in the UK;

 • The introduction and market acceptance of new technologies, products and services including artificial intelligence;

 • New competitors and new forms of competition;

 • The size and timing of customer orders (for retail distributed physical product);

 • The size and timing of capital expenditures by our customers;

 • Adverse changes in the credit quality of our customers and suppliers;

 • Changes in the pricing policies of, or the introduction of, new products and services by us or our competitors;

 • Changes in the terms of our contracts with our customers or suppliers;

 • The availability of products and schedule for deliveries from our suppliers; and

 • Variations in product costs and the mix of products sold.

 These trends and factors could adversely affect our business, results of operations and financial condition and diminish our ability to achieve our strategic objectives.

 We have been significantly short of capital needed to acquire parts for manufacture of our products to complete orders. At times, we have not had the cash available to make advance payments for the purchase of parts, and then, as a consequence, we would not receive the parts from our vendors required to finish a customer order. This would then delay the delivery of our products to customers and would also delay recognition of the resulting revenue and the receipt of cash from the customer. There can be no assurance that we will not operate at a loss during the current or future fiscal years.

 Our future profitability depends upon many factors, including several that are beyond our control. These factors include, without limitation:

 • changes in the demand for our products and services;

 • changes in the timing of desired customer deliveries;

 • the availability of working capital;

 • our ability to deliver on new product developments and introductions on a timely basis;

 • our loss of key customers or contracts;

 • our ability to hire engineers and other technical personnel;

 • the introduction of competitive products;

 • the failure to gain market acceptance of its new and existing products; and

 • changes in technology which cause some of our products to be obsolete.

 Sales, Business Development and Competitive Risks

 Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, our sales and revenue are difficult to predict and may vary substantially from period to period, which may cause our operating results to fluctuate significantly.

 The timing of our revenues is difficult to predict. Factors that may contribute to these fluctuations include our dependence on the defense industry, a limited number of customers, the nature and length of our sales cycles for our products and services, the duration and delivery schedules within our customer contracts and our ability to timely develop, produce and upgrade our products.

 Most of our revenues result from a limited number of relatively large orders that we receive from prime defense contractors and government agencies. We spend substantial time and resources on our sales efforts without any assurance that our efforts will produce any sales. In addition, purchases of our products are frequently subject to budget constraints (including constraints imposed by governmental agencies), multiple approvals, and unplanned administrative, processing and other delays. Even if we receive a purchase order from a customer, there may be circumstances or terms relating to the purchase that delay our ability to recognize revenue from that purchase, which makes our revenue difficult to forecast. As a result, it is difficult to predict whether a sale will be completed, the particular fiscal period in which a sale will be completed or the fiscal period in which revenue from a sale will be recognized. For these reasons, our operating results may vary significantly from quarter to quarter. Such unpredictable operating results may adversely impact the trading price of our common stock.

 Our sales are significantly dependent on the defense industry and a limited number of customers.

 Most of our current product and service offerings are directed towards the defense marketplace, which has a limited number of customers. If the defense market demand decreases, our sales may be less than projected with a resulting decline in revenues. As a result, our business depends upon continued U.S., Israeli, UK and other countries' government expenditures on defense systems for which we provide support. Our business, prospects, financial condition, operating results, and the trading price of our common stock could be materially harmed, among other causes, by the following:

 • Budgetary constraints, including mandated automatic spending cuts, affecting across-the-board government spending, or specific agencies in particular, and changes in available funding

 • A shift in expenditures away from defense programs that we support

 • U.S. government shutdowns due to, among other reasons, a failure by elected officials to fund the government and other potential delays in the appropriations process

 • Delays in the payment of our invoices by government payment offices; and

 • Changes in the political climate and general economic conditions, including a slowdown of the economy or unstable economic conditions and responses to conditions, such as emergency spending, that reduce funds available for other government priorities. The UK economy is now in a recession.

 Additionally, the loss of any one customer may have a material adverse effect on future operating results and financial condition. Our product backlog also has a number of risks and uncertainties such as the cancellation or deferral of orders, dispute over performance of our products and our ability to collect amounts due under these orders. If any of these events were to occur, actual shipments could be lower than projected and revenues could decline which would have an adverse effect on our operating results and liquidity.

 We face intense industry competition and product obsolescence, which, in turn, could increase our losses.

 We operate in an industry that is generally characterized by intense competition. Our competitors continuously engage in efforts to expand their business relationships with the same major defense contractors and the government with whom we enter into contracts with and will continue these efforts in the future, and the governments may choose to use other contractors. We believe that the principal competitive factors in our markets are breadth of product line, quality of products, stability, reliability and reputation of the provider, along with cost. Quantity discounts, price erosion, and rapid product obsolescence due to technological improvements are therefore common in our industry as competitors strive to retain or expand market share. Product obsolescence can lead to increases in unsaleable inventory that may need to be written off and, therefore, could reduce our profitability. Additionally, as we are seeing with Microsource, the U.S. military's decision to discontinue ordering certain aircraft where Microsource acts as a supplier, results in our loss of orders.

 Because our competitors have greater resources, we may not compete effectively.

 Several of our competitors, including, among others, K&L Microwave, Q Microwave, Amplitech, Qorvo, Northrop Grumman, Textron, Keysight, Rohde & Schwarz and National Instruments have substantially greater research and development, manufacturing, marketing, financial, technological personnel and managerial resources than us. These resources also make these competitors better able to withstand difficult market conditions than us. We cannot provide assurance that any products developed by these competitors will not gain greater market acceptance than any developed by us.

 Our products compete and will compete with similar, if not identical, products produced by our competitors. These competitive products could be marketed by well-established, successful companies that possess greater financial, marketing, distribution personnel, and other resources than we do. These companies can implement extensive advertising and promotional campaigns. They can introduce new products to new markets more rapidly. In certain instances, competitors with greater financial resources may be able to enter a market in direct competition with us, offering attractive marketing tools to encourage the sale of products that compete with our products or present cost features that customers may find attractive.

 The markets for some of our products (such as our commercial products in the UK) are also subject to specific competitive risks because these markets are highly price sensitive. Our competitors have competed in the past by lowering prices on certain products. If they do so again, we may be forced to respond by lowering our prices. This would reduce revenue and increase losses. Failure to anticipate and respond to price competition may also further reduce our revenue and increase our losses.

 If we are unable to monetize our legacy Giga-tronics Division, we may be required to discontinue its business.

 During the last two years the EW Test business has generated approximately $1.1 million per year in revenue despite the fact that we have spent over $26.0 million towards its development. We have a very small backlog for our EW test products as of the date of this Report. Accordingly, if we are unable to monetize our EW business, we may be forced to liquidate our remaining inventory and discontinue its operations.

 The sale of our products is dependent upon our ability to satisfy the proprietary requirements of our customers.

 We depend upon a relatively narrow range of products for the majority of our revenue. Our success in marketing our products is dependent upon their continued acceptance by our customers. In some cases, our customers require that our products meet their own proprietary requirements. If we are unable to satisfy such requirements, or forecast and adapt to changes in such requirements, our business could be materially harmed.

 If we fail to anticipate and adequately respond to rapid technological changes in our industry, including evolving industry-wide standards, in a timely and cost-effective manner, our business, financial condition and results of operations would be materially and adversely affected.

 Rapid technology changes in our industry require us to anticipate, sometimes years in advance, which technologies and/or distribution platforms our products must take advantage of in order to make them competitive in the market at the time they are released. Therefore, we usually start our product development with a range of technical development goals that we hope to be able to achieve for our customers. We may not be able to achieve these goals, or our competition may be able to achieve them more quickly than we can. In either case, our products may be technologically inferior to competitive products, or less appealing to consumers, or both. If we cannot achieve our technology goals for our customers within the original development schedule of our products, then our customers may opt for competitive offerings or we may delay products until these technology goals can be achieved, which may delay or reduce revenue and increase our development expenses. Alternatively, we can increase the resources employed in research and development in an attempt to accelerate our development of new technologies, either to preserve promised delivery date to our customers or to keep up with our competition, which would increase our development expenses and adversely affect our results of operations.

 Performance and Operational Risks

 If we are unable to identify, attract, train and retain qualified personnel, especially our design and technical personnel, our business and results of operations would be materially and adversely affected and we may not be able to effectively execute our business strategy.

 Our performance and future success largely depends on its continuing ability to identify, attract, train, retain and motivate qualified personnel, including its management, sales and marketing, finance and in particular its engineering, design and technical personnel. For example, we currently have a limited number of qualified personnel for the assembling, tuning and testing processes. Members of our technical staff are nearing retirement, and it may be difficult to replace them, given their experience and expertise. To the extent skilled engineering and manufacturing personnel can be beneficially utilized across divisions, the Company will look to do so. In addition, we will need additional staff to drive Microphase's forecasted growth and to allow Enertec to handle more large orders. Further Entertec's recruiting efforts are challenged by the war in Israel and the priority of the military. We do not know whether we can expand our workforce as needed. Our engineering, design and technical personnel represent a significant asset. The competition for qualified personnel in the defense industry in the U.S., UK and Israel is intense and constrains our ability to attract qualified personnel. The loss of the services of one or more of our key employees, especially our key engineering, design and technical personnel, or its inability to attract, retain and motivate qualified personnel could have a material adverse effect on our business, financial condition and operating results.

 Performance problems in our products or problems arising from the use of our products together with other vendors' products may harm our business and reputation.

 Products as complex as those we produce may contain unknown and undetected defects or performance problems. For example, it is possible that one of our products might not comply with stipulated specifications under all circumstances. In addition, our customers generally use our products together with their own products and products from other vendors. As a result, when problems occur in a combined equipment environment, it may be difficult to identify the source of the problem. A defect or performance problem could result in lost revenues, increased warranty costs, diversion of engineering and management time and effort, impaired customer relationships and injury to our reputation generally.

 Our EW test and training products are complex and could have unknown defects or errors, which may increase our costs, harm our reputation with customers, give rise to costly litigation, or divert our resources from other purposes.

 Our EW test and training systems are extremely complex. Despite testing, our initial products contained defects and errors and may in the future contain defects, errors or performance problems following the sale or when new versions or enhancements are released, or even after these products have been used by our customers for a period of time. These problems could result in expensive and time-consuming design modifications or warranty charges, delays in the introduction of new products or enhancements, significant increases in our service and maintenance costs, diversion of our personnel's attention from our product development and sales efforts, exposure to liability for damages, damaged customer relationships, and harm to our reputation, any of which could have a material adverse impact on our results of operations. In addition, increased development and warranty costs could be substantial and could reduce our operating margins.

 We face risks related to production delays, delays of customer orders and the relatively high selling price of our RADAR/EW testing platform.

 Our EW test and training platform has been a primary product development focus for the legacy Giga-tronics Division for the last several years. Presently, this product has no backlog. However, delays in completing its initial development, together with early design and manufacturing issues and longer than anticipated sales cycles have contributed to our inability to generate material sales. Additionally, the average selling price of our EW test and training system is considerably higher than our prior general-purpose test and measurement products, which requires additional internal approvals on the part of the customer and generally leads to longer sales cycles. Our financial condition may also cause potential customers to delay, postpone or decide against placing orders for our products. Continued longer than anticipated sales cycles in the future, or delays in production and shipping volume quantities, could have a material adverse impact on our operating results and liquidity.

 Our business could be negatively impacted by cybersecurity threats and other security threats and disruptions.

 As a defense contractor, we face certain security threats, including threats to our information technology infrastructure, attempts to gain access to our proprietary or classified information, threats to physical security, and domestic terrorism events. Our information technology networks and

 related systems are critical to the operation of our business and essential to our ability to successfully perform day-to-day operations. We are also involved with information technology systems for certain customers and other third parties, which generally face similar security threats. Cybersecurity threats in particular, are persistent, evolve quickly and include, but are not limited to, computer viruses, attempts to access information, denial of service and other electronic security breaches believe that we have implemented appropriate measures and controls and invested in skilled information technology resources to appropriately identify threats and mitigate potential risks, but there can be no assurance that such actions will be sufficient to prevent disruptions to mission critical systems, the unauthorized release of confidential information or corruption of data. A security breach or other significant disruption involving these types of information and information technology networks and related systems could:

 • disrupt the proper functioning of these networks and systems and therefore its operations and/or those of certain of its customers;

 • result in the unauthorized access to, and destruction, loss, theft, misappropriation or release of, our proprietary, confidential, sensitive or otherwise valuable information, our operating companies or their customers, including trade secrets, which others could use to compete against us or for disruptive, destructive or otherwise harmful purposes and outcomes;

 • compromise national security and other sensitive government functions;

 • require significant management attention and resources to remedy the damages that result;

 • subject us to claims for breach of contract, damages, credits, penalties or termination; and

 • damage our reputation with its customers and the U.S, the UK and Israel, and the public generally.

 Any or all of the foregoing could have a negative impact on its business, financial condition, results of operations and cash flows.

 Failure of our information technology infrastructure to operate effectively could adversely affect our business.

 We depend heavily on information technology infrastructure to achieve our business objectives. If a problem occurs that impairs this infrastructure, the resulting disruption could impede our ability to record or process orders, manufacture and ship in a timely manner, or otherwise carry on business in the normal course. Any such events could cause us to lose customers or revenue and could require us to incur significant expense to remediate.

 Earthquakes and other events could have a material adverse effect on our business, financial condition and results of operations.

 Microsource and our Giga-tronics Division are located in the San Francisco Bay Area near known earthquake fault zones and is vulnerable to significant damage from earthquakes. We are also vulnerable to other natural disasters, epidemics, such as COVID-19, and other events that could disrupt our operations that may be beyond our control. In addition, the war in Israel make our Enertec facility vulnerable to rocket attacks and potential invasion because it is located near the Lebanese boundary. We do not carry insurance for earthquakes and we may not carry sufficient business interruption insurance to compensate us for losses that may occur. Any losses or damages we incur could have a material adverse effect on our operating results, cash flows and success as an overall business.

 Supply chain disruptions and our inability to procure necessary component parts for our products have materially and adversely affected our results of operations and could materially and adversely affect our results of operations in the future.

 We manufacture some components for our products, but we rely on subcontract manufacturers to supply components for many of our product offerings. Our reliance upon such subcontract manufacturers involves several risks, including reduced control over manufacturing costs, delivery times, reliability and quality of components, unfavorable currency exchange fluctuations, and continued inflationary pressures on many of the raw materials used in the manufacturing of our products. On occasion, particularly with more complex video and filter assemblies, we may experience parts availability/shortage issues resulting from lower-than-expected production yields, necessitating faster and unexpected use of components planned for later ordering periods and thus causing shortages. If we were to encounter a shortage of key manufacturing components from limited sources of supply, or experience manufacturing delays caused by reduced manufacturing capacity, the inability of our subcontract manufacturers to procure raw materials, the loss of key assembly subcontractors, difficulties associated with the transition to our new subcontract manufacturers or other factors, we could experience lost revenue, increased costs, and delays in, or cancellations or rescheduling of, orders or shipments, any of which would materially harm our business.

 We may not be able to procure necessary key components for our products, or we may purchase too much inventory.

 The defense industry, and the electronics industry as a whole, can be subject to business cycles. During periods of growth and high demand for our products, we may not have adequate supplies of inventory on hand to satisfy our customers' needs. Furthermore, during these periods of growth, our suppliers may also experience high demand and, therefore, may not have adequate levels of the components and other materials that we require to build products so that it can meet our customers' needs. Our inability to secure sufficient components to build products for our customers could negatively impact our sales and operating results. We may choose to mitigate this risk by increasing the levels of inventory for certain key components assuming we have available cash resources. Increased inventory levels can increase the potential risk for excess and obsolescence should our forecasts fail to materialize or if there are negative factors impacting our customers' end markets. If we purchase too much inventory, we may have to record additional inventory reserves or write-off the inventory, which could have a material adverse effect on our gross margins and on our results of operations.

 We depend on a limited number of major customers for a significant portion of our revenue. The loss of any of these customers, or the substantial reduction in the quantity of products that they purchase from us, would materially adversely affect our business and results of operations.

 Our operating companies typically depend upon a limited number of major customers to generate a significant portion of its revenue. For the years ended December 31, 2023 and 2022, Enertec derived approximately to 98% and 89%, respectively, of its revenues from two customers. In each of those years, 75% and 45% of Microphase's revenues came from the same three customers. However, there is no assurance that the customers, which account for the great proportion of sales in our operating companies will continue placing further orders beyond the backlog orders on hand now. Among the factors that affect future orders are:

 • We have no intellectual property rights beyond trade secrets for the equipment we manufacture;

 • We are subject to competition from many manufacturers of purpose-built electronics;

 • We introduce a new upgraded version of the equipment which may not meet the customer's needs;

 • Changing technology may make our products less useful to the customer;

 • The customer may decrease the size of its orders or seek to reduce our selling price at any time;

 • The customer may elect to use manufacturers other than our operating companies; and

 If one or more of our major customers reduce or cancel their orders scaling back some of their activities, our revenue would be significantly reduced. Furthermore, reduction or diversions in defense spending may lead to reduced demand for our products, which could, in turn, have a material adverse effect on our business and results of operations. If the financial condition of one or more of our major customers were to deteriorate, or if such customers have difficulty acquiring investment capital due to any of these or other factors, a substantial decrease in our revenue would likely result.

 If we fail to effectively manage our growth, our business and operating results could be harmed.

 We are experiencing growth in our business with our increase in revenue in 2023 and expected increase this year. This growth will place significant demands on our management, operational and financial infrastructure. If we do not manage our growth effectively, the quality of our products and services could suffer, which could negatively affect our operating results. To effectively manage our growth, we must continue to improve our operational, financial and management controls and reporting systems and procedures. These systems improvements may require significant capital expenditures and management resources including hiring a full-time comptroller. Failure to implement these improvements could hurt our ability to effectively manage our growth and would in its turn have a material adverse impact on our business and future operating results.

 Our strategic focus on purpose-built electronics solutions and concurrent cost reduction plans may be ineffective or may limit our ability to compete.

 We devote significant resources to developing and manufacturing designed-in electronics solutions for our customers. Each product typically represents a uniquely tailored solution for a specific customer's requirements. Failure to meet these customer product requirements or a failure to meet production schedules and/or product quality standards may put us at risk with one or more of these customers. Moreover, changes in market conditions and changes in the needs and requirements of our customers may affect their purchasing decisions. The loss of one or more of our significant custom electronics solution customers could have a material adverse impact on our revenue, business or financial condition.

 We have implemented a series of initiatives designed to increase efficiency and reduce costs. While we believe that these actions will have a positive impact, they may not be sufficient to achieve the required operational efficiencies that will enable us to respond more quickly to changes in the market or result in the improvements in our business that we anticipate. Early in 2024, we implemented a reduction in force and reduction in office space in our U.S. operations. We may be forced to take additional cost-reducing initiatives, including those involving personnel, which may negatively impact our results of operations due to severance and other related costs. In addition, there is the risk that such measures could have long-term adverse effects on our business by reducing our pool of talent, decreasing or slowing improvements in our products or services, making it more difficult for us to respond to customers, limiting our ability to increase production quickly if and when the demand for its solutions increases and limiting our ability to hire and retain key personnel. These circumstances could adversely affect our operating results.

 A significant portion of our contracts are fixed-price contracts that could subject us to losses in the event of cost overruns or a material increase in inflation.

 We negotiate most of our contracts on a fixed-price basis which allows us to benefit from cost savings but also subject us to the risk of potential cost overruns, particularly for firm fixed-price contracts, because we assume the entire cost burden. If our initial estimates are incorrect, we can lose money on these contracts. Government contracts can expose us to potentially large losses because the government can hold us responsible for completing a project or, in certain circumstances, paying the entire cost of our replacement by another provider regardless of the size or foresee ability of any cost overruns that occur over the life of the contract. Because many of these contracts involve new technologies and applications, unforeseen events such as technological difficulties, fluctuations in the price of raw materials, problems with our suppliers and cost overruns, can result in the contractual price becoming less favorable or even unprofitable to us. The U.S., the UK and the Israel are experiencing

 a significant increase in inflation, which could have a significant adverse impact on the profitability of these contracts. Furthermore, if we fail to meet contract deadlines or specifications, we may need to renegotiate contracts on less favorable terms, be forced to pay penalties or liquidated damages or suffer major losses if the customer exercises its right to terminate. In addition, some of our contracts have provisions relating to cost controls and audit rights, and if we fail to meet the terms specified in those contracts we may not realize their full benefits. Cost overruns could have an adverse impact on our operating results.

 Many of our operating companies purchase a significant amount of their components and products outside of the countries in which they operate.

 With the exception of Microphase, Microsource and the Giga-tronics Division which source all of their components from U.S. suppliers, and Enertec which sources most of its parts in the U.S., we purchase a majority of our components from foreign manufacturers. In addition, we have a substantial majority of our commercial products assembled, packaged, and tested by subcontractors located outside the U.S. These activities are subject to the uncertainties associated with international business operations, including trade barriers and other restrictions, changes in trade policies, governmental regulations, currency exchange fluctuations, reduced protection for intellectual property, war and other military activities, terrorism, changes in social, political, pandemic, or economic conditions, and other disruptions or delays in production or shipments, any of which could have a materially adverse effect on our business and operating results.

 If we are unable to satisfy our customers' specific product quality, certification or network requirements, our business could be disrupted, and our financial condition could be harmed.

 Our customers demand that our products meet stringent quality, performance and reliability standards. We have, from time to time, experienced problems in satisfying such standards. Defects or failures have occurred in the past, and may occur in the future, relating to our product quality, performance and reliability. From time-to-time, our customers also require us to implement specific changes to our products to allow these products to operate within their specific network configurations. If we are unable to remedy these failures or defects or if we cannot complete such required product modifications, we could experience lost revenue, increased costs, including inventory write-offs, warranty expense and costs associated with customer support, delays in, or cancellations or rescheduling of, orders or shipments and product returns or discounts, any of which would harm our business.

 Risks Related to our Foreign Operations

 Because we have a material subsidiary that operates in Israel, the war which began October 7, 2023 may have a material adverse effect on our future results of operations and financial condition.

 Enertec, a subsidiary of the Company, is an Israeli corporation which has its offices and engineering and assembly facility located in Karmiel, Israel, which is near the border with Lebanon. Enertec is a material subsidiary and through December 31, 2023, approximately 41% of the Company's revenues were derived from Enertec.

 The war in Israel poses significant risks to Enertec including:

 • If Hezbollah enters the war or continues launching rockets into Israel, it could destroy Enertec's facility. Enertec has no alternative facility and the cost of locating a new facility and equipping it would effectively cause it to cease operations for at least six months.

 • Although most of Enertec's management and engineering and other staff are too old to serve in the military, any war-related injuries to them could result in a material adverse effect on Enertec's operations;

 • Even if Enertec is not materially damaged by rockets, Israel has a system of bomb shelters designed to protect its citizens. To the extent Enertec's employees are required to enter bomb shelters, it will create a material distraction and affect its ability to deliver products.

 • A prolonged war causing injuries and deaths in Israel could divert Enertec's staff from their duties to Enertec. Further some employees have had family members killed to date and future deaths and injuries could adversely affect employees' efforts.

 • As the war continues, there has been increasing friction between Israel and the U.S. as the U.S. seeks to pressure Israel to enter into a ceasefire. If this were to result in reduced U.S. aid for Israel, it is possible that Enertec's business could be adversely affected.

 In addition, Israel-based companies and companies doing business with Israel have been the subject of an economic boycott by members of the Arab League and certain other predominantly Muslim countries, including Iran, since Israel's establishment. Although Israel has entered into various agreements with certain Arab countries and the Palestinian Authority, and various declarations have been signed in connection with efforts to resolve some of the economic and political problems in the Middle East, we cannot predict whether or in what manner these problems will be resolved as these countries are opposed to Israel's continuing the war. Wars and acts of terrorism have resulted in significant damage to the Israeli economy, including reducing the level of foreign and local investment.

 Our commercial insurance does not cover losses that may occur as a result of events associated with war and terrorism. Although the Israeli government currently covers the reinstatement value of direct damages that are caused by terrorist attacks or acts of war, we cannot assure you

 that this government coverage will be maintained or that it will sufficiently cover its potential damages. Any losses or damages incurred by us could have a material adverse effect on our business.

 If the war continues, it could have a material adverse effect on our operations and financial condition.

 Many of Enertec's employees are obligated to perform military reserve duty in Israel, which could have a disruptive impact on our business.

 Certain number of Enertec's officers and employees may be obligated to perform annual reserve duty in the Israel Defense Forces and are subject to being called up for active military duty at any time. All Israeli citizens who have served in the army are subject to an obligation to perform reserve duty until they are between 40 and 49 years old, depending upon the nature of their military service. These military service obligations could have a disruptive impact on our business, if hostilities develop in the future, which may adversely affect our business.

 We depend on international sales for a material portion of our revenue.

 Sales to customers outside of North America accounted for more than two thirds of our net revenue for the years ended December 31, 2023 and 2022, respectively. We expect that international sales will continue to represent a material portion of our total revenue. International sales are subject to the risks of international business operations as described above, as well as generally longer payment cycles, greater difficulty collecting accounts receivable, and currency restrictions. These risks include the following:

 • unexpected changes in practices, tariffs, export quotas, custom duties, trade disputes, tax laws and treaties, particularly due to economic tensions and trade negotiations or other trade restrictions;

 • different labor laws and regulations;

 • exposure to many stringent and potentially inconsistent laws and regulations relating to privacy, data protection, and information security;

 • changes in a specific country's or region's political or economic conditions;

 • risks resulting from fluctuations of currency exchange rates;

 • risks relating to the trade protection regulations and measures in the U.S. or in other jurisdictions;

 • limitations on our ability to reinvest earnings from operations derived from one country to fund the capital needs of its operations in other countries;

 • limited or potentially unfavorable intellectual property protection; and

 • exposure to liabilities under anti-corruption and anti-money laundering laws, including the U.S. Foreign Corrupt Practices Act of 1977 (the "FCPA"), and similar applicable laws and regulations in other jurisdictions.

 International sales are also subject to the export laws and regulations of the U.S. and other countries. Further, our subsidiaries in the U K and Israel are subject to local regulation which may increase our costs.

 Any one or more of these factors could increase our costs and adversely affect our results of operations.

 A material portion of our revenue and expenses is denominated in foreign currencies, so fluctuations in exchange rates could have a material adverse effect on our operating results.

 We face foreign exchange risks because a significant portion of our revenue and expenses is denominated in foreign currencies. Further, some suppliers to Enertec and Relec require payment in U.S. dollars, which also exposes us to risk. Generally, U.S. dollar strength adversely impacts the translation of the portion of our revenue that is generated in foreign currencies into the U.S. dollar. For the years ended December 31, 2023 and 2022, a substantial portion of our revenue was denominated in currencies other than U.S. dollars. Our results of operations could also be negatively impacted by a strengthening of the U.S. dollar as a large portion of our costs are U.S. dollar denominated. We also have foreign exchange risk exposure with respect to certain of its assets that are denominated in currencies other than the functional currency of its subsidiaries, and its financial results are affected by the re-measurement and translation of these non-U.S. currencies into U.S. dollars, which is reflected in the effect of exchange rate changes on cash, cash equivalents, and restricted cash on the consolidated statements of cash flows. Strengthening of the U.S. dollar could materially and adversely affect our results of operations and financial condition. For the year ended December 31, 2023 we had a gain from foreign currency exchange adjustment of $74,000 and for the year ended December 31, 2022 we had a gain from foreign currency exchange adjustment of $45,000.

 Legal Risks

 Our limited ability to protect our proprietary information and technology may adversely affect our ability to compete, and our products could infringe upon the intellectual property rights of others, resulting in claims against us, the results of which could be costly.

 Many of our products consist entirely or partly of proprietary technology owned by us. Although we seek to protect our technology through a combination of copyrights, trade secret laws and contractual obligations, these protections may not be sufficient to prevent the wrongful appropriation of our intellectual property, nor will they prevent our competitors from independently developing technologies that are substantially equivalent or superior to our proprietary technology. In addition, the laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the U.S. In order to defend our proprietary rights in the technology utilized in our products from third party infringement, we may be required to institute legal proceedings, which would be costly and would divert our resources from the development of our business. If we are unable to successfully assert and defend our proprietary rights in the technology utilized in our products, our future results could be adversely affected.

 Although we attempt to avoid infringing known proprietary rights of third parties in our product development efforts, we may become subject to legal proceedings and claims for alleged infringement from time to time in the ordinary course of business. Any claims relating to the infringement of third-party proprietary rights, even if not meritorious, could result in costly litigation, divert management's attention and resources, require us to reengineer or cease sales of our products or require us to enter into royalty or license agreements which are not advantageous to us. In addition, parties making claims may be able to obtain an injunction, which could prevent us from selling our products in the U.S. or abroad.

 We may in the future be involved in lawsuits to protect or enforce our patents or the patents of our licensors, which could be expensive, time-consuming and unsuccessful.

 Competitors may infringe on our patents, trade secrets or the patents of our licensors. To counter such infringement or unauthorized use, we may be required to file infringement claims, or we may be required to defend the validity or enforceability of such patents, which can be expensive and time-consuming. In an infringement proceeding, a court may decide that either one or more of our patents or our licensors' patents is not valid or is unenforceable or may refuse to stop the other party from using the technology at issue because our patents do not cover that technology. An adverse result in any litigation or defense proceedings could put one or more of our patents at risk of being invalidated or interpreted narrowly and could put our patent applications at risk of not issuing.

 Interference proceedings filed by third parties or brought by us may be necessary to determine the priority of inventions regarding our patents or patent applications or those of our partners or licensors. An unfavorable outcome could require us to cease using the related technology or to license rights to it from the prevailing party. Our business could be harmed if the prevailing party does not offer us a license on commercially reasonable terms. Our defense of litigation or interference proceedings may fail and, even if successful, may cause us to incur substantial costs and distract the attention of our management and other employees. We may not be able to prevent, alone or with our licensors, misappropriation of our intellectual property rights, particularly in countries where the laws may not protect those rights as fully as in the U.S.

 Because of the substantial amount of discovery required in intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our common stock.

 Regulatory and Compliance Risks

 Our businesses are subject to government procurement laws and regulations.

 We must comply with certain laws and regulations relating to the formation, administration and performance of government contracts. These laws and regulations affect how we conduct business with the government, including the business that we do as a subcontractor to large prime contractors that contract directly with the government. In complying with these laws and regulations, we incur additional costs. These costs may increase in the future, thereby reducing our margins, which could have an adverse effect on our business, financial condition, results of operations and cash flows. Failure to comply with these regulations and requirements could lead to fines, penalties, repayments, or compensatory or treble damages, or suspension or debarment from government contracting or subcontracting for a period of time. Among the causes for debarment are violations of various laws, including those related to procurement integrity, export control, government security regulations, employment practices, protection of the environment, accuracy of records, proper recording of costs and foreign corruption. The termination of a government contract or relationship as a result of any of these acts would have an adverse impact on our operations and could have an adverse effect on our standing and eligibility for future government contracts.

 Some U.S. federal statutes and regulations provide for penalties, including automatic debarment based on actions such as violations of the U.S. False Claims Act or the U.S. Foreign Corrupt Practices Act. The suspension or debarment in any particular case may be limited to a facility, contract or subsidiary involved in the violation or could be applied to our entire Company in severe circumstances. Even a narrow scope suspension or debarment could result in negative publicity that could adversely affect our ability to renew contracts and to secure new contracts, both with governments and private customers, which could materially and adversely affect our business, financial condition and results of operations.

 If we fail to comply with anti-bribery, anti-corruption, anti-money laundering laws, and similar laws, or allegations of such failure, it could have a material adverse effect on our business, financial condition and operating results.

 We are subject to various anti-bribery, anti-corruption, anti-money laundering laws, including the FCPA, the U.S. Travel Act, and the USA PATRIOT Act. In addition, we are subject to the UK Bribery Act 2010, the Proceeds of Crime Act 2002, Chapter 9 (sub-chapter 5) of the Israeli Penal Law, 1977, the Israeli Prohibition on Money Laundering Law–2000, and possibly other similar laws in countries outside of the U.S. in which we conduct our business or seek to sell our products. Anti-corruption and anti-bribery laws have been enforced aggressively in recent years and are interpreted broadly to generally prohibit companies, their employees, agents, representatives, business partners, and third-party intermediaries from authorizing, offering, or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector.

 We, our employees, agents, representatives, business partners and third-party intermediaries may have direct or indirect interactions with officials and employees of government agencies or state-owned or affiliated entities and may be held liable for the corruptor other illegal activities of these employees, agents, representatives, business partners or third-party intermediaries even if we do not explicitly authorize such activities.

 These laws also require that we keep accurate records and maintain internal controls and compliance procedures designed to prevent any such actions. While we have policies and procedures to address compliance with such laws, we cannot assure you that none of our employees, agents, representatives, business partners or third-party intermediaries will take actions in violation of our policies and applicable law, for which we may be ultimately held responsible. In addition, we may be held liable for violations committed of the FCPA or similar foreign laws by companies that we acquire.

 Any alleged or actual violation of the FCPA or other applicable anti-bribery, anti-corruption laws, and anti- money laundering laws could result in whistleblower complaints, investigations, enforcement actions, fines and other criminal or civil sanctions, adverse media coverage, loss of export privileges, or suspension or termination of government contracts. Responding to any investigation or enforcement action would require significant attention of our management and resources, including significant defense costs and other professional fees. Failure to comply with anti-bribery, anti-corruption, anti-money laundering laws, and similar laws, or allegations of such failure, could therefore have a material adverse effect on our business, results of operations, financial condition and future prospects.

 We are subject to certain governmental regulatory restrictions and regulations relating to international sales.

 Some of our products are subject to ITAR, which is interpreted, enforced and administered by the U.S. Department of State. ITAR regulation controls not only the export, import and trade of certain products specifically designed, modified, configured or adapted for military systems, but also the export of related technical data and defense services as well as foreign production. Any delays in obtaining the required export, import or trade licenses for products subject to ITAR regulation and rules could have a material adverse effect on our business, financial condition, and/or operating results. In addition, changes in U.S. export and import laws that require us to obtain additional export and import licenses or delays in obtaining export or import licenses currently being sought could cause significant shipment delays and, if such delays are too great, could result in the cancellation of orders. Any future restrictions or charges imposed by the U.S. or any other country on our international sales or foreign subsidiary could have a materially adverse effect on our business, financial condition, and/or operating results. In addition, from time to time, Gresham has entered into contracts with the Israeli MOD which were governed by the U.S. Foreign Military Financing program ("FMF"). Any such future sales would be subject to these regulations. Failure to comply with FMF rules could subject us to investigations that could lead to civil, administrative and possible criminal prosecution, which have a material adverse effect on its financial condition, operating results and/or prospects for obtaining future government business. Failure to comply with ITAR or FMF rules could also have a material adverse effect on our financial condition, and/or operating results.

 We are also required to obtain export licenses before filling foreign orders for many of our products that have military or other governmental applications. The U.S. Export Administration regulations control technology exports like our products for reasons of national security and compliance with foreign policy, to guarantee domestic reserves of products in short supply and, under certain circumstances, for the security of a destination country. Thus, any foreign sales of our products requiring export licenses must comply with these general policies. Compliance with these regulations is costly, and these regulations are subject to change, and any such change may require us to improve our technologies, incur expenses or both in order to comply with such regulations.

 If we fail to comply with the rules under the Sarbanes-Oxley Act of 2002 related to accounting controls and procedures, or if we discover additional material weaknesses and deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult.

 If we fail to comply with the rules under the Sarbanes-Oxley Act of 2002 related to disclosure controls and procedures, or, if we discover additional material weaknesses and other deficiencies in our internal control and accounting procedures, our stock price could decline significantly and raising capital could be more difficult. Section 404 of the Sarbanes-Oxley Act requires annual management assessments of the effectiveness of our internal control over financial reporting.

 We have noted the following deficiencies that we believe to be material weaknesses:

 • At December 31, 2023, we did not have sufficient resources in our accounting function, which restricted our ability to gather, analyze and properly review information related to financial reporting in a timely manner.

 • Due to our size and nature, the Company is not able to maintain appropriate segregation of conflicting duties as it is not always possible and is not economically feasible.

 • Our primary user access controls to ensure appropriate authorization and segregation of duties that would adequately restrict user and privileged access to the financially relevant systems and data to appropriate personnel were not designed and/or implemented effectively. We did not design and /or implement sufficient controls for program change management to certain financially relevant systems affecting our processes.

 • Due to the lack of appropriate personnel necessary for financial reporting, the Company has failed to properly account for complex financial instruments.

 While we want to begin remediating these material weaknesses, our management has been distracted with our liquidity concerns. When we can obtain the cash resources, we expect to increase our accounting staff. With our recent reductions of employees, we did not lay off any accounting personnel. However, our vice president of finance who acted as our comptroller resigned last year and we must replace him. Moreover, effective internal controls are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud. If we cannot provide reliable financial reports or prevent fraud, our business and operating results could be harmed, investors could lose confidence in our reported financial information, and the trading price of our common stock could drop significantly.

 Risks Related to the Ownership of Our Common Stock

 Because of limited volume of our common stock, you may not be able to sell many shares without depressing the price.

 There has been a relatively illiquid public market for our common stock on the OTCQB. The average daily trading volume of our shares of common stock during 2023 was approximately 9,250 shares and during 2024 through the date of the Report was approximately 1,700 shares. Accordingly, you may not be able to trade a large amount of our common stock without depressing the price. Further, the low market cap may impede our ability to solve our liquidity issues and prevent us from listing our common stock on a national securities exchange.

 Our stock price may be volatile, which could result in substantial losses to investors and litigation.

 In addition to changes to market prices based on our results of operations and the factors discussed elsewhere in this "Risk Factors" section, the market price of and trading volume for our common stock may change for a variety of other reasons, not necessarily related to our actual operating performance. The capital markets have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our common stock. In addition, the average daily trading volume of the securities of small companies can be very low, which may contribute to future volatility. Factors that could cause the market price of our common stock to fluctuate significantly include:

 • the results of operating and financial performance and prospects of Gresham and other companies in our industry;

 • strategic actions by us or our competitors, such as acquisitions or restructurings;

 • announcements of innovations, increased service capabilities, new or terminated customers or new, amended or terminated contracts by our competitors;

 • the public's reaction to our press releases, other public announcements, and filings with the SEC;

 • lack of securities analyst coverage or speculation in the press or investment community about us or market opportunities in the defense electronics industry;

 • changes in government policies in the U.S. and, as our international business increases, in other foreign countries;

 • changes in earnings estimates or recommendations by securities or research analysts who track our common stock or failure of our actual results of operations to meet those expectations;

 • market and industry perception of our success, or lack thereof, in pursuing our growth strategy;

 • changes in accounting standards, policies, guidance, interpretations or principles;

 • any lawsuit involving us, our solutions or our product offerings;

 • arrival and departure of key personnel;

 • sales of common stock by us, our investors or members of our management team; and

 • changes in general market, economic and political conditions in the U.S. and global economies or financial markets, including those resulting from natural or man-made disasters or the banking crisis.

 Any of these factors, as well as broader market and industry factors, may result in large and sudden changes in the trading volume of our common stock and could seriously harm the market price of our common stock, regardless of our operating performance. This may prevent you from being able to sell your shares at or above the price you paid for your shares, if at all. In addition, following periods of volatility in the market price of a

 company's shares, stockholders often institute securities class action litigation against that company. Our involvement in any class action suit or other legal proceeding could divert our senior management's attention and could adversely affect our business, financial condition, results of operations and prospects.

 The rights of the holders of common stock may be impaired by the potential additional issuance of preferred stock.

 Our charter documents give our board of directors (the "Board"),the right to create new series of preferred stock. As a result, our Board may, without stockholder approval, issue preferred stock with voting, dividend, conversion, liquidation or other rights which could adversely affect the voting power and equity interest of the holders of common stock. Preferred stock, which could be issued with the right to more than one vote per share, could be utilized as a method of discouraging, delaying or preventing a change of control. The possible impact on takeover attempts could adversely affect the price of our common stock. Although we have no present intention to issue any shares of preferred stock, we may issue such shares in the future.

 Because our shares of common stock are subject to the penny stock rules, it is more difficult to buy our shares.

 The SEC has adopted rules that regulate broker-dealer practices in connection with transactions in penny stocks. Penny stocks are generally equity securities with a price of less than $5.00, other than securities registered on certain national securities exchanges or authorized for quotation on certain automated quotation systems, provided that current price and volume information with respect to transactions in such securities is provided by the exchange or system. Unless we are listed on the NYSE American, or the Nasdaq Stock Market or if the price of our common stock is less than $5.00 (as it is now), our common stock will be a penny stock. The penny stock rules require a broker-dealer, before a transaction in a penny stock not otherwise exempt from those rules, to deliver a standardized risk disclosure document containing specified information. In addition, the penny stock rules require that before effecting any transaction in a penny stock not otherwise exempt from those rules, a broker-dealer must make a special written determination that the penny stock is a suitable investment for the purchaser and receive (i) the purchaser's written acknowledgment of the receipt of a risk disclosure statement; (ii) a written agreement to transactions involving penny stocks; and (iii) a signed and dated copy of a written suitability statement. These disclosure requirements may have the effect of reducing the trading activity in the secondary market for our common stock, and therefore stockholders may have difficulty buying their shares. Also it is increasingly harder for stockholders to deposit penny stock with broker-dealers which may discourage others from buying our common stock.

 We do not anticipate paying any dividends on our common stock for the foreseeable future.

 We have not paid any dividends on our common stock to date, and we do not anticipate paying any such dividends in the foreseeable future. We anticipate that any earnings will be retained to finance the implementation of our operational business plan and expected future growth.

 ITEM 1B. UNRESOLVED STAFF COMMENTS

 Not applicable.

 ITEM 1C. CYBERSECURITY

 Like all companies that utilize technology, we are subject to threats of breaches of our technology systems. To mitigate the threat to our business, we take a comprehensive approach to cybersecurity risk management. Our management actively oversees our risk management program, including the management of cybersecurity risks. We have established policies, standards, processes and practices for assessing, identifying, and managing material risks from cybersecurity threats, including those discussed in our Risk Factors. We have devoted significant financial and personnel resources to implement and maintain security measures to meet regulatory requirements and stakeholder expectations, and we intend to continue to make significant investments to maintain the security of our data and cybersecurity infrastructure. We have established and maintain a Cybersecurity Maturity Model Certification ("CMMC") compliance program and are working to meet all applicable deadlines. While there can be no guarantee that our policies and procedures will be properly followed in every instance or that those policies and procedures will be effective, we believe that the Company's investment in people and technologies have contributed to a culture of continuous improvement that has put the Company in a position to protect against potential compromises and we do not believe that risks from prior cybersecurity threats have materially affected our business to date. We can provide no assurance that there will not be incidents in the future or that past or future attacks will not materially affect us, including our business strategy, results of operations, or financial condition.

 Risk Management and Strategy

 At a high level, the key objectives for the Company's cybersecurity program are to implement and sustain effective security controls to stop intrusion attempts and to maintain and continuously improve its ability to respond to attacks and incidents. Success in achieving these objectives relies upon using quality technology solutions, cultivating and maintaining a team of skilled professionals, and improving processes continuously. Our cybersecurity program in particular focuses on the following key areas:

 Risk Assessment: At least annually, we conduct a cybersecurity risk assessment that takes into account information from internal stakeholders, known information security vulnerabilities, and information from external sources, including reported security incidents that have impacted other companies, industry trends, and evaluations by third parties and consultants. The results of the assessment are used to develop initiatives to enhance our security controls, make recommendations to improve processes, and inform a broader Company-wide risk assessment that are then reported to our members of management.

 Technical Safeguards: We regularly assess and deploy technical safeguards designed to protect our information systems from cybersecurity threats. Such safeguards are regularly evaluated and improved based on vulnerability assessments, cybersecurity threat intelligence and incident response experience.

 Incident Response and Recovery Planning: We have established comprehensive incident response and recovery plans that guide our response in the event of a cybersecurity incident. We continuously test and evaluate the effectiveness of those plans.

 Vendor Risk Management: We have implemented a vendor risk management program, which is designed to identify and mitigate cybersecurity threats associated with our use of third-party service providers. Such providers are subject to security risk assessments at the time of on-boarding, contract renewal, and upon detection of an increase in risk profile. We use a variety of inputs in such risk assessments, including information supplied by providers in response to detailed questionnaires and meetings as well as information from third parties. In addition, we require our providers to meet appropriate security requirements, controls and responsibilities and investigate security incidents that have impacted our third-party providers, as appropriate. Contract language, purchasing decisions, and/or technology implementation strategies are frequently adjusted as a result of this process.

 Education and Awareness: Our policies require each of our employees to contribute to our data security efforts. We regularly remind employees of the importance of handling and protecting data, including through annual privacy and security training to enhance employee awareness of how to detect and respond to cybersecurity threats. As part of that educational process, we periodically simulate cybersecurity threats to the Company and review/assess employee responses. In this regard, the Company has implemented policies and procedures for all employees including: (i) information security/cybersecurity policies, which are internally available for all employees, (ii) information security/cybersecurity awareness training; (iii) a clear escalation process which employees can follow in the event an employee notices something suspicious; and (iv) ensuring that information security/cybersecurity is part of the employee performance evaluation and/or disciplinary process.

 ITEM 2. PROPERTIES

 Our principal executive offices are located in an executive suite in Scottsdale, Arizona. We maintain a large facility with marketing, sales, and engineering offices and manufacturing departments in a 20,595 square foot facility in Livermore, California, which we have occupied since March 2024. We also lease an additional 32,000 square foot facility in Shelton, Connecticut.

 In addition, we lease facilities internationally. In September 2010, Gresham Power entered into a long term lease for its 25,000 square-foot facility in Salisbury, UK, where it designs, develops, manufactures, markets and distributes commercial and military power products for the European market. Sales and service support staff for its European network of distributors are located within the building together with other functions, such as engineering and administration. Gresham Power's lease expires in September 2024. Further, in June 2021, Enertec entered into a five-year lease with an option to extend the lease for an additional five-year term for its 32,900 square-foot facility in Karmiel, Israel, where it manufactures specialized electronic systems for the Israel military market and medical systems for a multinational pharmaceutical company. In July 2020, Relec entered into a 10-year lease for its 7,490 square-foot facility in Dorset, UK, where it markets and distributes power electronics and display solutions for mission critical rail, industrial, medical, telecoms and military applications.

 We believe our existing and planned facilities and offices are adequate to meet our current needs and are being utilized consistently with our past practice. We consistently look for opportunities to minimize costs related to office space through improved efficiencies and intend to make changes to leased facilities in the future as appropriate to reflect changes in worldwide operations and headcount.

 We currently anticipate that our current leased spaces will be sufficient to support our current and foreseeable future needs.

 ITEM 3. LEGAL PROCEEDINGS

 From time-to-time, we are subject to various claims and legal proceedings that arise in the ordinary course of business. We accrue for losses related to litigation when a potential loss is probable and the loss can be reasonably estimated.

 As of the date of the Report, we were not party to any material legal proceedings for which a loss was probable or an amount was accrued.

 ITEM 4. MINE SAFETY DISCLOSURES

 Not applicable.

 ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

 Our common stock is traded on the OTCQB using the symbol "GIGA". The number of record holders of our common stock as of April 8, 2024 was 94. A significantly larger number of stockholders may be "street name" or beneficial holders, whose shares of record are held by banks, brokers and other financial institutions.

 Dividend Policy

 We have not paid cash dividends on our common stock in the past and have no current plans to do so in the future, believing our available capital is best used to fund our operations, including product development and enhancements.

 ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

 Gresham designs, manufactures and distributes purpose-built electronics equipment, automated test solutions, power electronics, supply and distribution solutions, as well as radio, microwave and millimeter wave communication systems and components for a variety of applications with a focus on the global defense industry and the healthcare market.

 Gresham has two subsidiaries Microsource and Gresham Holdings. Gresham is a majority owned subsidiary AAI and currently operates as an operating segment of AAI. Gresham Holdings has three wholly-owned subsidiaries, Gresham Power, Relec, and Enertec, and one majority owned subsidiary, Microphase. Our operations consist of three business segments:

 • Radio Frequency Solutions – consists of Microphase which is located in Connecticut. Microphase designs and manufactures custom microwave hardware products for military applications and generates revenue primarily through production contracts for custom engineered components and RADAR filters.

 • Precision Electronic Solutions – consists of one subsidiary and one division, namely Enertec located in Israel and what we call our Giga-tronics Division. Enertec develops and supplies advanced command & control, test and calibration systems for use in failsafe military and medical applications. The Giga-tronics Business consists of Microsource, a wholly-owned subsidiary which develops and manufactures sophisticated RADAR filters used in fighter aircraft, and our "EW Test and Training" Division, which serves the defense electronics market with a signal generation platform. We refer to this later business as our "Giga-tronics Division".

 • Power Electronics & Displays – consists of two subsidiaries, namely Gresham Power and Relec located in the UK which primarily engineer and provide integrated, mobile power electronics and display solutions that distribute and supply continuous, dependable, clean low voltage power.

 We are focused on products that are getting designed in to military systems such as fighter jet, ships and ground vehicles or missiles, which provide a recurring revenue stream for years to come and eliminate competition because the cost of replacing designed in products is prohibitive for both the competition and the customer.

 Recent Trends and Uncertainties

 We are in the process of aggressively managing our cash flow and reducing our expenses. As part of this endeavor, in March 2024 we implemented a reduction in our work force and recently moved to a smaller facility in California. We continue to have working capital issue. See "Risk Factors".

 Critical Accounting Estimates

 Our consolidated financial statements have been prepared in accordance with GAAP. In reading and understanding this discussion of results of operations, liquidity and capital resources, you should be aware of key policies, judgments and assumptions that are important to the portrayal of financial conditions and results.

 The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires us to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Note 3 of Notes to the Consolidated Financial Statements describe the significant accounting policies and methods used in the preparation of the Consolidated Financial Statements. The Company believes its most critical accounting policies to be the recognition of revenue and costs on production contracts. These critical accounting policies are impacted significantly by judgments, assumptions, and estimates used in the preparation of the Consolidated Financial Statements and actual results could differ materially from the amounts reported based on these policies.

 Revenue Recognition

 Revenues are reported in operating results based upon the ratio that incurred costs bear to total estimated contract costs with related cost of revenues recorded as the costs are incurred. Each month management reviews estimated contract costs through a process of aggregating actual costs incurred and estimating additional costs to completion based upon the current available information regarding labor, outside services, materials, overhead costs, and status of the contract. The effect of any change in the estimated gross margin rate for a contract is reflected in revenues in the period in which the change is known. Provisions for the full amount of anticipated losses on contracts are made in the period in which they become determinable.

 Significant judgment is used in evaluating the financial information for certain contracts to determine an appropriate budget and estimated cost. The Company evaluates this information continuously and bases its judgments on historical experience, design specifications, and expected costs for material and labor.

 The Precision Electronic Solutions group generated net revenue of $19.6 million during the year ended December 31, 2023, a 40% increase over the same period in the prior year. The increase was primarily due to an increase of $2.5 million in revenue from Enertec's defense business as well as the addition of $2.5 million of the Giga-tronics Division and Microsource revenue.

 The Power Electronics & Displays group was largely unchanged for the year ended December 31, 2023 in comparison to the year ended December 31, 2022.

 The RF Solutions group recognized a 34% increase in revenue by Microphase largely due to $1.7 million in shipments to a new customer.

 Backlog as of December 31, 2023 increased 2% compared to December 31, 2022.

 The Power Electronics & Displays group experienced a 25% decline in backlog primarily due to a 68% decline in bookings at Gresham Power and a 26% decline in bookings at Relec.

 The RF Solutions group experienced a 28% increase in backlog primarily due to orders totaling $5.5 million received from one prime contractor in calendar 2023.

 Gross profit was $9.8 million or 26% of revenue for the year ended December 31, 2023, in comparison to $8.5 million or 28% for the year ended December 31, 2022. The primary reason for the low 26% gross margin was due to the Giga-tronics Business, which had very low revenues of $4.0 million in 2023 causing negative gross margins due to fixed overheads and variable costs which did not reduce proportionally to revenue. Excluding the Giga-tronics Business, gross margins were 30.5% in 2023.

 Total operating expenses decreased 10% or $2.6 million for the year ended December 31, 2023 with lower non-cash impairment charges as compared to the year ended December 31, 2022. Research and development expenses increased by 32% primarily due to the Giga-tronics Business, which incurred $1.28 million in research and development expenses for the year 2023 as compared to $403,000 for the period of September 8, 2022 to December 31, 2022.

 Selling, general and administrative expenses increased by 21% primarily due the issuance cost of $1.2 million of the Notes and Warrants (see Note 13. Senior Secured Convertible Notes and Warrants), as well as the added general and administrative costs of the Giga-tronics Business in 12-month period ended December 31, 2023 as compared to the period of September 8, 2022 to December 31, 2022.

 The Company determined that the goodwill of $3.2 million and the intangibles of $1.5 million associated with the Microphase business was impaired due to a poor fourth quarter in 2023 and continued losses over a 5-year period and the Company recorded these non-cash impairments within operating expenses for the year ended December 31, 2023.

 Microphase's business has rebounded with the revenue for the first quarter increasing by 25% sequentially. With a backlog of approximately $11.9 million as of March 31, 2024 and anticipated deliveries, we expect the second quarter will increase by 40% sequentially Further we believe Microphase's 2024 revenues may be the highest since it was acquired by Gresham Holdings.

 The Company determined that the goodwill of $10.5 million associated with the acquisition of the Giga-tronics Business was impaired due to the lack of backlog, the decline in revenue and forecasts, and recorded this non-cash impairment within operating expenses for the year ended December 31, 2022.

 Total other expenses increased by $315,000 or 15% for the year ended December 31, 2023 as compared to the year ended December 31, 2022.

 Interest expense, related party in 2022 was due to interest on existing notes at Microphase to AAI prior to the Business Combination, there were no such interest after September 8, 2022.

 We recorded a gain in the fair value of the senior secured convertible notes, related party of $7,000 in 2023 as compared to a loss of $1.1 million in 2022 (see Note 14. Notes Payable, Related Parties, net).

 For the year ended December 31, 2023, interest increased by $129,000 primarily due to interest on the Senior Secured Convertible Notes (see Note 13. Senior Secured Convertible Notes and Warrants). These notes had a change in fair value of $3.7 million in 2023 and a gain in the fair value of the associated warrants of $2.4 million in 2023. In addition the Company issued warrants on modification of the Senior Secured Convertible Note with a fair value of $0.7 million.

The $2.6 million decrease in net losses for the year ended December 31, 2023 was primarily due to lower operating expenses and the lower impairment charges of goodwill partially offset by higher impairment charges of intangibles.

 Non-GAAP Financial Measures

 A non-GAAP financial measure is generally defined by the SEC as a numerical measure of a company's historical or future performance, financial position or cash flows that includes or excludes amounts from the most directly comparable measure under GAAP. Non-GAAP financial measures should be viewed in addition to, and not as an alternative to, our reported results prepared in accordance with GAAP. Users of this financial information should consider the types of events and transactions that are excluded from these measures.

 We measure our operating performance in part based on earnings before interest, taxes, depreciation and amortization ("EBITDA"). We also measure our operating performance based on "Adjusted EBITDA," which we define as EBITDA adjusted for share based compensation and certain one-time income or expense items. EBITDA and Adjusted EBITDA are non-GAAP financial measures that are commonly used, but neither is a recognized accounting term under GAAP. We use EBITDA and Adjusted EBITDA to monitor and facilitate internal evaluation of the performance of our business operations, to facilitate external comparison of our business results to those of others in our industry, and to plan and evaluate our operating budgets. We believe that our measures of EBITDA and Adjusted EBITDA provide useful information to the investing public regarding our operating performance and our ability to service debt and fund capital expenditures and may help investors understand and compare our results to other companies that have different financing, capital and tax structures. Neither EBITDA nor Adjusted EBITDA should be considered in isolation or as a substitute for, but as a supplement to, income or loss from operations, net income or loss, cash flows from operating activities, or other income or cash flow data prepared in accordance with GAAP.

 In the following reconciliation, we provide amounts as reflected in our accompanying consolidated financial statements unless otherwise noted.

 Liquidity and Capital Resources

 On December 31, 2023, we had cash of $3.6 million (excluding restricted cash of $0.7 million), compared to cash and cash of $2.2 million at December 31, 2022. The increase in cash was primarily due to pre-payments on defense contracts. Our cash is substantially all held by our subsidiaries.

 Net cash used by operating activities totaled $2.8 million for the year ended December 31, 2023, compared to net cash used in operating activities of $5.0 million for the year ended December 31, 2022. The primary use of cash for the year ended December 31, 2023 was due to the net loss of $15.3 million offset by non-cash changes in the fair value of convertible notes, by the non-cash impairment of goodwill and intangibles of $4.7 million. and warrants and depreciation and amortization expenses. The primary use of cash for the year ended December 31, 2022 was due to net loss of $18.4 million offset by the non-cash impairment of goodwill of $10.5 million.

 Net cash used in investing activities for the year ended December 31, 2023 was $234,000 for purchases of equipment. Cash used in investing activities for the year ended December 31, 2022 was $4.3 million which was primarily due to the acquisition of the Giga-tronics Business.

 Cash provided by financing activities for the year ended December 31, 2023 was $4.9 million which was primarily due to proceeds from the Senior Secured Convertible Notes (see Note 13. Senior Secured Convertible Notes and Warrants) and from the notes payable, related parties.

 Cash provided by financing activities for the fiscal year ended December 31, 2022 was $9.7 million which was primarily due to proceeds from notes payable, related parties.

 Liquidity

 Our primary sources of liquidity have historically been funded by AAI and in January 2023 by two other lenders who lent the Company $3.0 million. Without the availability of working capital from AAI, unless we are successful in securing additional financing from third parties, we believe that we will not have sufficient cash to meet our needs over the next 12 months including $4.600,000 of convertible notes due on October 11, 2024. We do not have sufficient working capital to meet our needs for the next 12 months – See "Risk Factors."

 Even as we reduce our operations in California and possibly elsewhere, we need to complete a material financing which will provide the working capital to support our meeting our backlog and future orders. In addition, we must obtain a financing to repay the $4.6 million Senior Secured Convertible Notes (the "Senior Notes") due this fall. Any financing will likely have onerous terms and be dilutive of our stockholders. As disclosed elsewhere in this Report, if we default on the Senior Notes, the interest rate increases from 7% to 18%, the Company is required to pay 20% of its consolidated revenues monthly on each interest payment date in reduction of the principal amount of the Senior Notes then outstanding and the holders have the right to require the Company to prepay the Senior Notes at 125% of principal.

 As of April 5, 2024, the Company has approximately $4.1 million in cash.

 Our ability to obtain additional financing is subject to several factors, including market and economic conditions, our performance and investor and lender sentiment with respect to us and our industry. If we are unable to raise additional financing in the near term as needed, our operations and production plans may be scaled back or curtailed and our operations and growth would be impeded.

 Our near term fixed commitments for cash expenditures are primarily for payments for employee salaries, operating leases and inventory purchase commitments. Due to the deterioration of the Giga-tronics Division including its Microsource subsidiary, we have lacked sufficient capital to pay our payables. To assist with our liquidity issues, our executive officers have agreed to accept the minimum wage of $1,240 per week and to defer their remaining salaries for a single pay period. In 2023 we borrowed a total of $50,000 from our Chief Financial Officer and $50,000 from a director, of which the loan to our Chief Financial Officer remains unpaid. As a result of our liquidity issues, we need to raise approximately $5.0 million to meet our short-term working capital needs, not including the $4.6 million we owe which is due on October 11, 2024. While we are engaged in discussions with AAI and another lender about possible solutions, we cannot assure you that we will be successful in solving our liquidity issues. In addition to risk factors disclosed in this Prospectus, one of the solutions is based upon our common stock beginning to trade actively. We cannot assure you that will occur.

 Our Financings

 The AAI Financing

 In December 31, 2022 (the "AAI Closing Date"), we entered into an Exchange Agreement (the "Exchange Agreement") with AAI, to exchange the Senior Secured Convertible Promissory Note due February 14, 2023 in the principal face amount of $4,250,000 dated September 8, 2022 and any accrued interest thereon for a convertible note in the principal amount of $4,382,740 due December 31, 2024 (the "Exchange Note").

 The Exchange Note bears interest at 10% per annum. The Exchange Note is, at the option of AAI, convertible into our common stock at a conversion price equal to the lesser of (i) $0.78 per share, or (ii) the VWAP Price (as defined in the Exchange Note) on such date less a 20% discount to such VWAP Price, but in no event less than $0.25 per share. In addition, all principal and outstanding interest under the Exchange Note will automatically convert to our common stock upon (i) the consummation of a public offering of securities in which we receive net proceeds (net of underwriters' discounts and selling commissions) of at least $25 million (a "Qualified Public Offering"), in which case the conversion price shall be the price at which the common stock is sold to the public, provided, however, that no underwriters' discounts or selling commissions shall be imposed on such conversion, (ii) the consummation of a private or public offering of shares of common stock that is not a Qualified Public Offering but that results in the net proceeds (net of underwriters' discounts and selling commissions) to us of at least $5 million (a "Non-Qualified Offering"), in which case the conversion price shall be the price at which common stock is sold in such Non-Qualified Offering less a 25% discount or (iii) December 31, 2024, in which case the conversion price shall be the VWAP Price less a 25% discount to such VWAP Price.

 Our obligations under the Exchange Agreement and the Exchange Note are secured by a lien on all of our assets and our wholly-owned subsidiaries pursuant to the Security Agreement dated December 31, 2022 (the "Exchange Security Agreement"), by and among us, our two of our wholly-owned subsidiaries, Microsource, Inc. and Gresham Holdings, Inc., and AAI.

 On the AAI Closing Date, we also entered into a Securities Purchase Agreement (the "Purchase Agreement") by and between us and Ault Lending, whereby we issued Ault Lending a 10% Senior Secured Convertible Promissory Note in the principal amount of $6,750,000 (the "Secured Note") and five-year warrants to purchase 2,000,000 shares of our common stock (the "AAI Warrants"). The AAI warrants were recently exercised. They were exercisable for five years from December 31, 2022 at an exercise price of $0.01. In connection with the issuance of the Secured Note, as of the AAI Closing Date, Ault Lending surrendered for cancellation a term note dated November 12, 2021, in the principal face amount $1,300,000 previously issued by us, including accrued but unpaid interest thereon in the amount of $123,123. In addition, on the AAI Closing Date advances previously made by AAI Lending to us in the aggregate amount of $4,067,469 were rolled into the Secured Note. Pursuant to the Purchase Agreement, as additional consideration for the issuance of the Secured Note, Ault Lending agreed to provide us an additional $1,259,407 no later than May 31, 2023.

 The Secured Note is due December 31, 2024, and bears interest at 10% per annum. The voluntary conversion and automatic conversion price of the Secured Note are similar to the conversion price of the Exchange Note.

 With a limited exception, the Senior Secured Note contains a most favored nations provision with respect to our future financings.

 With limited exceptions, we also agreed to certain negative covenants that will require the prior approval of the holder of the Secured Note to incur indebtedness (other than permitted indebtedness), enter into variable rate transactions, incur indebtedness for borrowed money, purchase money indebtedness or lease obligations that would be required to be capitalized on a balance sheet prepared in accordance with U.S. Generally Accepted Accounting Principles, or guaranty the obligations of any other person, in an aggregate amount at any time outstanding in excess of $1,000,000 in any individual transaction or $2,500,000 in the aggregate. Our obligations under the Purchase Agreement and the Secured Note are secured by a lien on all of our assets of and our wholly-owned subsidiaries pursuant to a Security Agreement, dated December 31, 2022 (the "AAI Security Agreement") by and among us, our wholly-owned subsidiaries, Microsource and Gresham and Ault Lending and AAI.

 Pursuant to the Purchase Agreement, we and two of our wholly-owned subsidiaries, Microsource and Gresham, entered into a Guaranty Agreement, dated December 31, 2022 with Ault Lending. Each such subsidiary guaranteed to Ault Lending the payment of the Secured Note.

 In connection with the issuance of the Exchange Note and the Secured Note, we granted AAI and Ault Lending certain mandatory and piggyback registration rights pursuant to two registration rights agreements.

 On January 3, 2023 we, AAI and Ault Lending entered into a letter agreement whereby the parties agreed that notwithstanding any obligations in any of the foregoing transaction documents we shall not be required to reserve more than 150% of the shares issuable under the Exchange Note and the Secured Note using $0.78 per share (subject to adjustment for stock splits, stock dividends or combinations) plus reservation of one share for each outstanding share issuable under the warrants (subject to adjustment for stock splits, stock dividends or combinations).

 AAI and Ault Lending are limited to owning no more that 4.99% of our common stock based upon beneficial ownership limitations contained in the Secured Note and the Exchange Note.

 The January 2023 Private Placement

 On January 11, 2023, the Company entered into a Securities Purchase Agreement with the Lenders pursuant to which the Company sold to the Lenders $3.3 million 10% original issue discount Notes and five-year warrants to purchase a total of 1,666,666 shares of common stock, no par value for total gross proceeds of $3,000,000. The net proceeds were used primarily for working capital.

 The Notes are secured by our assets pursuant to a Security Agreement entered into for such purpose, and are senior to the indebtedness payable to AAI, pursuant to a Subordination Agreement entered into in connection with the Securities Purchase Agreement.

 The Notes mature on nine months from the issuance date, or October 6, 2023. The Notes accrue interest at a rate of 6% per annum payable monthly, which increases to 18% upon an event of default. In addition, under the Notes upon an event of default we are required to pay 20% of our consolidated revenues monthly on each interest payment date in reduction of the principal amount of the Notes then outstanding.

 The Notes provide for certain events of default which include failure to maintain effectiveness of the registration statement under the Registration Rights Agreement (as described below), suspension of trading of our common stock for five consecutive trading days, failure to timely deliver shares issuable upon conversion of the Notes or exercise of the Warrants, failure to timely make payments under the Notes, default under other indebtedness, and certain other customary events of default, subject to certain exceptions and limitations.

 Upon an event of default, the holders will have the right to require us to prepay the Notes at a 125% premium. Further, upon a bankruptcy event of default or a change of control event, we will be required to prepay the Notes at a premium. If the conversion price falls below $0.25, we may also elect to prepay the notes at a 125% premium.

 Pursuant to the Notes, upon an event of default one of the investors is entitled to cause Jonathan Read, our Chief Executive Officer and one of our directors, to resign from his positions with the Company. Mr. Read executed and delivered to the investor an undated letter of resignation to that effect, which the investor may cause to be dated and released upon the occurrence of an event of default.

 The Notes are convertible at a conversion price equal to the greater of (a) 90% of the VWAP for the 10 trading days prior to the conversion date and (b) $0.25 per share, subject to adjustment including downward adjustment upon any dilutive issuance of securities. Each holder's conversion is subject to a 4.99% beneficial ownership limitation which may be increased to 9.99% on 61 days' notice from the holder.

 The Notes contain customary restrictive covenants including covenants against incurring new indebtedness or liens, changing the nature of its business, transfers of assets, transactions with affiliates, and issuances of securities, subject to certain exceptions and limitations.

 We repaid our existing line of credit with Western Alliance Bank which had an existing balance of approximately $59,000.

 The warrants entitle the holders to purchase a total of 1,666,666 shares of common stock for a five-year period from issuance, at an exercise price of the lower of (A) $0.78 and (B) 90% of the lowest VWAP for the 10 trading days prior to the date of the exercise, subject to adjustment including downward adjustment upon any dilutive issuance of securities. Because our common stock will not be listed on a national securities exchange by October 6, 2023, the maturity date of the Notes, the number of shares of common stock that may be purchased upon exercise of the warrants will be doubled on that date, without an adjustment to the exercise price.

 Each holder's exercise is subject to a 4.99% beneficial ownership limitation which may be increased to 9.99% on 61 days' notice from the holder. The Warrants may be exercised cashlessly if the registration statement covering the resale of the shares of common stock issuable upon exercise is not effective as required under the Registration Rights Agreement.

 We are required to maintain a reserve of authorized but unissued shares of common stock initially equal to approximately 15,000,000 shares of common stock, subject to reduction as the Notes and warrants are converted and exercised, respectively.

 Spartan Capital Securities, LLC (the "Placement Agent") served as placement agent in the offering and received a cash commission in the amount of 8% of the gross proceeds, or $240,000. In addition, we paid the Placement Agent an expense allowance of $30,000. Furthermore, we agreed to issue the Placement Agent five-year warrants to purchase a number of shares of common stock equal to 8% of the total number of shares of common stock underlying the Notes and warrants sold in the offering, or 1,200,000 shares. The placement agent warrants have an exercise price of 110% of the warrant exercise price.

 Under the SPA we reimbursed the Lenders a total of $60,000 out of the proceeds from the offering for fees and expenses incurred in connection therewith.

 On October 11, 2023, the "Company entered into an Exchange and Waiver Agreement (the "Agreement") with the two Lenders.

 Under the Agreement, the Lenders exchanged the Notes for new Senior Secured Convertible Promissory Notes (the "New Notes"), which are substantially identical to the Notes, including the conversion price, except: (A) the maturity date of the New Notes is October 11, 2024, (B) the

 principal of each New Note is $2,000,000, (C) the interest rate is 7% per year, and (D) the New Notes have a working capital covenant pursuant to which the Company's working capital, excluding any debt owed to Ault Lending or any of its affiliates and the New Notes, shall increase by a minimum of $250,000 per quarter for the quarters ending December 31, 2023 and March 31, 2024 and $500,000 per quarter thereafter while either of the New Notes remain outstanding (such exchange, the "Exchange").

 Pursuant to the Agreement, the Company also issued to each Lender a five-year warrant to purchase 333,333 shares of the Company's common stock (the "New Warrants"), which are substantially identical to the Prior Warrants.

 As required by the Agreement, Ault Lending extended the maturity dates of the 10% Senior Secured Promissory Notes (as defined in the Agreement) to January 15, 2025 and consented to the accrual of all interest while either New Note remains outstanding. Accordingly, on October 11, 2023, the Company entered into a Waiver Agreement with (AAI and together with Ault Lending, "Ault") and Ault Lending pursuant to which Ault waived certain rights in furtherance of the foregoing.

 The New Notes are secured and senior to the indebtedness payable to AAI.

 The Prior Warrants provided that the number of shares of Company common stock issuable thereunder ("Warrant Shares") would be doubled (with no adjustment to the exercise price) upon the failure of the Company's common stock to be listed for trading on a national securities exchange operated by The Nasdaq Stock Market or the New York Stock Exchange (an "Uplist Transaction") to occur by the Maturity Date of the Notes (as such terms are defined in the Prior Warrants). Because the Uplist Transaction failed to occur by the Maturity Date, on October 11, 2023 the Company issued additional warrants to the Buyers to increase the Warrant Shares by 833,333 additional Warrant Shares per Buyer.

 Present Liquidity

 Even with the reduction of our operations in California and elsewhere, we need to complete a material financing which will provide the working capital to support our meeting our backlog and future orders. In addition, we must obtain a financing to repay the $4.6 million Notes due on October 11, 2024. Any financing may have onerous terms and be very dilutive to our shareholders. As disclosed elsewhere in this Prospectus, if we default on the Notes, the consequences may be severe and include the resignation of the Chief Executive Officer.

 As of April 5, 2024, the Company has approximately $4.1 million in cash mostly in foreign countries. As a result, we have struggled to meet our payroll and have relied on loans from one of our directors and one officer to meet our payroll. See "Related Party Transactions."

 We expect AAI will continue funding us in the near future. Without the availability of working capital from AAI, unless we are successful in securing additional financing from third parties, we believe that we will not have sufficient cash to meet our needs over the next 12 months as well as AAI's position as a secured creditor or to repay the Notes.

 Our ability to obtain additional financing is subject to several factors, including market and economic conditions, our performance and investor and lender sentiment with respect to us and our industry. If we are unable to raise additional financing in the near term as needed, our operations and production plans may be scaled back or curtailed and our operations and growth would be impeded.

 Our near term fixed commitments for cash expenditures are primarily for payments for employee salaries, operating leases, inventory purchase commitments and public company costs.

 ITEM 9A. CONTROLS AND PROCEDURES

 Evaluation of Disclosure Controls and Procedures

 We have established disclosure controls and procedures designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms and is accumulated and communicated to management, including the principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

 Our principal executive officer and principal financial officer, with the assistance of other members of the Company's management, have evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of the end of the period covered by this Report. Based upon our evaluation, each of our principal executive officer and principal financial officer has concluded that the Company's internal control over financial reporting was not effective as of the end of the period covered by this Report on Form 10-K due to the material weaknesses as described herein.

 A material weakness is a control deficiency (within the meaning of the Public Company Accounting Oversight Board (United States) Auditing Standard No. 2) or combination of control deficiencies that result in more than a remote likelihood that a material misstatement of the annual or interim financial statements will not be prevented or detected. Management has identified the following material weaknesses:

 • The Company does not have sufficient resources in its accounting function, which restricts its ability to gather, analyze and properly review information related to financial reporting in a timely manner.

 • Due to its size and nature, the Company is not able to maintain appropriate segregation of conflicting duties as it is not always possible and is not economically feasible.

 • Our primary user access controls (i.e., provisioning, de-provisioning, privileged access and user access reviews) to ensure appropriate authorization and segregation of duties that would adequately restrict user and privileged access to the financially relevant systems and data to appropriate personnel were not designed and/or implemented effectively. We did not design and/or implement sufficient controls for program change management to certain financially relevant systems affecting our processes.

 • Due to the lack of the appropriate personnel necessary for financial reporting, the Company failed to properly account for complex financial instruments.

 Planned Remediation

 Management continues to work to improve its controls related to our material weaknesses, specifically relating to user access and change management surrounding our information technology systems and applications. Management will continue to implement measures to remediate material weaknesses, such that these controls are designed, implemented, and operating effectively. The remediation actions include: (i) enhancing design and documentation related to both user access and change management processes and control activities; and (ii) developing and communicating additional policies and procedures to govern the area of information technology change management.

 We are currently working to improve and simplify our internal processes and implement enhanced controls to address the material weaknesses in our internal control over financial reporting and to remedy the ineffectiveness of our disclosure controls and procedures. These material weaknesses will not be considered to be remediated until the applicable remediated controls are operating for a sufficient period of time and management has concluded that these controls are operating effectively.

 Despite the existence of these material weaknesses, we believe that the consolidated financial statements included in the period covered by this Report on Form 10-K fairly present, in all material respects, our financial condition, results of operations and cash flows for the periods presented in conformity with U.S. generally accepted accounting principles.

 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(e) and 15d-15(e) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined effective could provide only reasonable assurance with respect to financial statement preparation and presentation.

 Our management conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2023, based on the framework in the Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "2013 Internal Control-Integrated Framework"). Based on our evaluation under the 2013 Internal Control-Integrated Framework, our management concluded that our internal control over financial reporting was not effective as of December 31, 2023 as a result of the material weaknesses described above.

 Changes in Internal Control over Financial Reporting

 Except as detailed above, there were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) that occurred during the quarter ended December 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

 Jonathan Read became our Chief Executive Officer and was appointed a director effective on September 8, 2022 with the closing of the Business Combination. Mr. Read has been Gresham's Chief Executive Officer since May 2019. He was a director of Red Cat Holdings, Inc., formerly known as Timefire VR, Inc., from August 18, 2017 to November 3, 2022 and was the Chief Executive Officer of Timefire VR, Inc. from October 2017 through May 2019 and from November 2015 to January 2017. From July 14, 2017 through July 20, 2018, Mr. Read served as a director of BTCS, Inc., a digital asset-related company. From 2005 through 2012, Mr. Read was the Chief Executive Officer of ECOtality Inc.

In 2013, ECOtality filed for Chapter 11 bankruptcy protection. In 2014, Mr. Read filed for bankruptcy. We believe that Mr. Read's management and public company experience, his experience in the defense industry and his role as Chief Executive Officer of the Company, give him the qualifications and skills to serve as one of our directors.

 Robin Shaffer has served as the Chief Technology Officer of Gresham Holdings since January 2022 and was appointed our Chief Operating Officer on January 2024. From July 2015 to October 2020, Mr. Shaffer served as Managing Principal of Sustainability Partners. Mr. Shaffer holds a BSnvE from Cal Poly SLO and an MBA from Marquette University.

 Our Directors

 The Board consists of seven directors. The names of our directors, their positions with the Company and their ages are set forth in the table below, followed by certain other information about them:

 Name

 Age

 Position

 Chief Executive Officer and Director

 Jeffrey Bentz

 Chairman of the Board of Directors

 William B. Horne

 Robert Smith

 William J. Thompson

 Thomas E. Vickers

 Set forth below is a brief biographical description of each of our directors who are not previously described above, including their business experience, director positions held currently or at any time during the last five years.

 Jeffrey Bentz is our Chairman of our Board since September 8, 2022. He has been a director of AAI since 2018. Mr. Bentz has been a director of AAI Disruptive Technologies Corp. [NYSE:ADRT] since December 2021. Mr. Bentz is an experienced businessman who has served since 1994 as President of North Star Terminal & Stevedore Company, a full-service stevedoring company located in Alaska and whose major areas of business include terminal operations and management, stevedore services, and heavy equipment operations. He also has served as a director and advisor to several private companies and agencies. We believe that Mr. Bentz's public company director experience, executive-level experience, including his operational and financial oversight of companies with multiple profit centers and his extensive experience in the real estate and commercial services industries give him the qualifications and skills to serve as one of our directors.

 William Horne has served as our director since September 8, 2022. He has been the Chief Executive Officer of AAI since January 2021 and a director since October 2016. He served as AAI's President from August 2020 until January 2021 and previously as its Chief Financial Officer since January 2018. He has been a director of Gresham since 2019. Mr. Horne served as the Chief Executive Officer and a director of AAI Disruptive Technologies Corporation (NYSE:ARDT) since January 2021.

Mr. Horne is a director and Chief Financial Officer of Avalanche International, Corp. Mr. Horne has served on the board of directors of Alzamend Neuro, Inc., a biotechnology firm dedicated to finding the treatment, prevention and cure for Alzheimer's Disease, since 2016. From January 29, 2024 to February 21, 2024 Mr. Horne served as a director of Risk On International, Inc. We believe that Mr. Horne's extensive financial and accounting experience in diversified industries and with companies involving complex transactions give him the qualifications and skills to serve as one of our directors.

 Robert Smith has served as our director since September 8, 2022. Mr. Smith has been a director of AAI Disruptive Technologies Corp. [NYSE:ADRT] since December 2021. He serves as the lead independent director of AAI and has been a director since September 2016. Previously, he was a director of AAI from November 2010 until May 2015. Mr. Smith has been a director of Risk On International, Inc. since October 13, 2023. He is currently a C-level executive consultant working with Bay Area high-tech firms on various strategic initiatives in all aspects of their business. We believe that Mr. Smith's executive-level experience, and his service on AAI's Board, give him the qualifications and skills to serve as one of our directors.

 John Regazzi has served as a member of our Board since 2006. He was our Chief Executive Officer from April 2006 until he resigned with the closing of the Business Combination. Mr. Regazzi retired as a full-time employee effective January 31, 2023 and is now a part-time employee. Previously he was appointed Co-Chief Executive Officer in June 2017 and Chief Technology Officer in August 2016. From 2006 to August 2016, he was the President and Chief Executive Officer of the Company. We believe that Mr. Regazzi's executive-level experience, including his previous service as our Chief Executive Officer, and his service on our Board, give him the qualifications and skills to serve as one of our directors.

 William Thompson served as Chairman of our Board from August 2016 and has been a member of our Board since 2011 and until the closing of the Business Combination as a director since then. Dr. Thompson served as our Acting Chief Executive Officer from August 2016 until June 2017. From April 2021 to August 2022 Dr. Thompson served as Chief Technology Officer of Safetonet Limited, a privately held cyber-safety business focused on protecting children from online harms that makes Net Nanny™ parental control software, and he is a partner at QFT Analytics, a private company that offers financial modeling and back-office solutions for small companies. We believe that Mr. Thompson's executive-level experience, including his previous service as our Acting Chief Executive Officer, and his service on our Board and as our Chairman of the Board give him the qualifications and skills to serve as one of our directors.

 Thomas Vickers has served as a member of our Board since September 2020. Since January 2020, Mr. Vickers has served as the President of Stack Financial Inc., a finance and accounting advisory firm that provides family office, Chief Financial Officer on demand, finance and accounting services to various clients. He has been a director of Veritas Farms, Inc., since October 1, 2020. From October 2012 to 2019, he served as Chief Financial Officer and Senior Vice President of Human Resources for OmniComm Systems Inc., a healthcare technology company, where he was a key member of the executive team that successfully completed that company's acquisition by Anju Software. At OmniComm he had primary responsibility for planning, implementing, managing and controlling all financial activities and worked directly with the Chief Executive Officer to determine budget, disbursements and expenditures of money and capital assets. He is a Chartered Financial Analyst. We believe that Mr. Vicker's extensive corporate finance and operations experience in diversified industries, and with companies involving complex transactions and his role as a chartered financial analyst give him the qualifications and skills to serve as one of our directors.

 Information About the Board and Committees of the Board

 Committees

 The Board has an Audit Committee, a Compensation Committee and a Corporate Governance and Nominating Committee.

 Each of the committees has a charter that is available on the investor relations section of the Company's website at

 Audit Committee

 The Audit Committee consists of Thomas E. Vickers (Chairman), Jeffrey Bentz and Robert Smith. The Audit Committee serves to monitor the effectiveness of the independent audit, as well as the Company's accounting, financial controls and financial reports. The Audit Committee must pre-approve all non-audit services provided by the independent public accounting firm.

 The Board has determined that Mr. Vickers has:

 (i) an understanding of generally accepted accounting principles and financial statements.

 (ii) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves;

 (iii) experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant's financial statements, or experience actively supervising one or more persons engaged in such activities;

 (iv) an understanding of internal control over financial reporting; and

 (v) an understanding of audit committee functions.

 Therefore, the Board determined that Mr. Vickers qualifies as the Audit Committee's financial expert for purposes of the requirements of the Sarbanes-Oxley Act of 2002.

 Compensation Committee

 The Compensation Committee consists of Jeffrey Bentz (Chairman), William J. Thompson and Will Horne. Each member of the committee is independent under the independence standards of the Nasdaq Stock Market. The Compensation Committee formulates recommendations to the Board regarding levels of compensation for management. In addition, in order to recognize the expected future contributions of key employees and provide an additional incentive for them to remain with the Company over the long-term, the Compensation Committee awards options to purchase shares of our common stock and other forms of equity awards. The Compensation Committee reviews and approves all stock options, other equity awards and executive compensation.

 Nominating and Governance Committee

 The Nominating and Governance Committee (the "Nominating Committee") consists of directors William J. Thompson (Chairman), John R. Regazzi and Thomas E. Vickers. The purpose of the Nominating Committee is to recommend persons for membership on the Board, to establish criteria and procedures for the selection of new directors, and to evaluate and recommend to our Board any revisions to our corporate governance guidelines.

 The Nominating Committee has no formal process for identifying and evaluating candidates. Existing directors identify suitable candidates as the need arises. The Board's policy is to consider any director candidate nominated or recommended by a shareholder in the same manner that it would consider a candidate nominated by the Board or Nominating Committee. In the past year, the Company did not receive any recommendations for director candidates from any shareholders and did not have an annual meeting of shareholders. Shareholder recommendations should be submitted in writing to the Company by mail at its main office at least 120 days in advance of the anniversary date of the mailing of notice of the previous year's annual meeting and should include sufficient biographical information (including all information that would be required to be disclosed in a proxy statement for a shareholder meeting at which directors are to be elected) for the committee to make an initial evaluation of the candidate's qualifications.

 The Nominating Committee has no formal policy on the consideration to be given to diversity in the nomination process, other than to seek candidates who have skills and experience that are appropriate to the position and complementary to those of the other board members or candidates.

 Director Independence

 Messrs. William J. Thompson and Thomas E. Vickers are considered to be independent, and the remaining directors are considered not to be independent, for purposes of membership on the Board and their respective Committees under the Listing Rules of The Nasdaq Stock Market.

 Code of Ethics

 The Company has adopted a Code of Ethics applicable to all directors, officers and employees. The Code of Ethics is posted on our website under the Governance portion of the Investor Relations section at

 Board Leadership Structure

 The positions of Chairman of the Board and Chief Executive Officer are currently held by different persons. The Board believes that having a separate chairman helps enable the Board to maintain an independent perspective on the activities of the Company and executive management. Periodically, the Board assesses the roles and the Board leadership structure to ensure the interests of the Company and the shareholders are best served.

 Board Risk Oversight

 The Company's senior management manages the risks facing the Company under the oversight and supervision of the Board. While the full Board is ultimately responsible for risk oversight at the Company, the Audit Committee assists the Board in fulfilling its oversight responsibilities with respect to risk in the areas of financial reporting and internal controls. Other general business risks such as economic and regulatory risks are monitored by the full Board.

 Insider Trading Policy

 The Company has implemented an Insider Trading Policy applicable to its officers and directors and employees with access to material nonpublic information, as well as such persons' family members, which generally prohibits such persons from conducting transactions involving the purchase or sale of the Company's securities during a blackout period. For this purpose, the term "blackout period" is defined in the Policy as a quarterly period beginning on the 10th calendar day of the third month of each of the first three fiscal quarters, and the first calendar day of the third month of the fourth fiscal quarter, an in each case ending at the close of business on the second trading day following the date of public disclosure of the financial results for such fiscal quarter or year. In addition, under the Policy the Company may impose "special" blackout periods, including when there are nonpublic developments that would be considered material for insider trading law purposes. The Policy also strictly prohibits and trading on material nonpublic information, regardless of whether such a transaction occurs during a blackout period.

 While the granting of options and other equity awards to officers, directors and other employees is not expressly addressed in the Insider Trading Policy described above, the Company follows the same principles set forth in such Policy when granting equity awards, including options, to its officers, directors and other employees with access to material nonpublic information. Generally the Board of Directors or Compensation Committee does not approve grants of such awards during a blackout period, and does not take material nonpublic information into account when determining the timing and terms of such an award. Further, the Company does not have a policy or practice of timing the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. A copy of our Insider Trading Policy was filed as Exhibit 19.1 to this Report.

 Policy Against Hedging Transactions

 Under the Company's Insider Trading Policy, all officers, directors and certain identified employees are prohibited from engaging in hedging transactions.

 Delinquent Section 16(a) Reports

 Section 16(a) of the Securities Exchange Act of 1934 requires our directors, executive officers, and persons who own more than 10% of our common stock to file initial reports of ownership and changes in ownership of our common stock and other equity securities with the SEC. These individuals are required by the regulations of the SEC to furnish us with copies of all Section 16(a) forms they file. Based solely on a review of the copies of the forms furnished to us, and written representations from reporting persons that no Forms 5 were required to report delinquent filings, we believe that all filing requirements applicable to our officers, directors and 10% beneficial owners were complied with during 2023.

 ITEM 11. EXECUTIVE COMPENSATION

 Compensation of Officers

 The following table provides information concerning compensation paid to, earned by or accrued with respect to (i) the Company's Chief Executive Officer, (ii) and the two other most highly compensated executive officers during the last fiscal year who were serving as of December 31, 2023 and whose total compensation exceeded $100,000, and (iii) up to two additional individuals who would qualify under (ii) above but for the fact that such individuals were not serving as executive officers of the Company as of December 31, 2023. We refer to these persons as the "Named Executive Officers." The determination of Named Executive Officers and the amounts reflected in the table give effect to the Business Combination which closed on September 8, 2022, and for this purpose reflect amounts paid, accrued or earned by or with respect to Gresham and its subsidiaries as if the Business Combination had occurred as of January 1, 2022, in accordance with SEC rules.

 Employment Agreements

 Upon the consummation of the Business Combination, Gresham's obligations under Employment Agreements and Offer Letters with its officers were assumed by the Company. The following describes such agreements as well as oral employment arrangements with our Named Executive Officers, other than Mr. Long.

 Jonathan Read. Effective on September 15, 2020, Gresham entered into a four-year Executive Employment Agreement with Mr. Read ("Read's Employment Agreement") to serve as its Chief Executive Officer. Read's Employment Agreement provides that Mr. Read receives a base salary of $250,000 per year, which will be subject to an upward adjustment as shall be determined by Gresham's Board, plus a $500 per month car allowance. In addition to a base salary and a car allowance, in the event Gresham achieves annual revenue of no less than $25,000,000, Mr. Read is eligible to receive an executive performance bonus for each such year based on Gresham's net income.

 Upon the termination of Mr. Read's employment, he will be entitled to receive any earned but unpaid base salary through the termination date, and any accrued but unused vacation. Further, unless Mr. Read's employment is terminated as a result of his death or disability or for "Cause" or Mr. Read terminates his Employment Agreement without "Good Reason" (as defined in Read's Employment Agreement) Mr. Read would be entitled to severance payments as follows: (i) 12 months of Mr. Read's base salary and (ii) a prorated bonus amount.

 Lutz Henckels. Mr. Henckels is employed under an oral agreement that pays him a salary of $280,000 per year.

 Robin Shaffer. Mr. Shaffer entered into an agreement with Gresham Holdings in 2021 with an annual salary of $235,000. The Company increased his base salary to $255,000 in January 2024, when he was appointed Chief Operating Officer.

 John Regazzi. On January 31, 2023 (the "Effective Date") we entered into a Termination and Release Agreement with Mr. John Regazzi a director, who served as our Chief Executive Officer until the closing of the Business Combination, whereby Mr. Regazzi agreed to resign as a full-time employee effective as of the Effective Date. We agreed to pay Mr. Regazzi (a) $17,500 in unpaid expenses, payable on the Effective Date, (b) $82,266 in unpaid deferred salary payable on the Effective Date; (c) $100,000 in an unpaid bonus related to the acquisition of Gresham payable in essentially equal installments over an 18-month commencing in January 2025;(d) $325,000 in retirement compensation payable over

 an 18-month period commencing in January 2025; and (e) COBRA reimbursement until such time as Mr. Regazzi can transition to Medicare. In addition, to this compensation, we owe Mr. Regazzi $36,000 in paid time off compensation, which will be payable over 12 months. Mr. Regazzi is remaining as a part-time employee at the rate of $125 per hour for up to 20 hours per month.

 Change-In-Control Arrangements

 In order to reinforce and encourage the continued attention and dedication of certain key members of management, we entered into Severance Agreements with certain executive officers including Mr. Regazzi (our then Chief Executive Officer), Mr. Henckels, Mr. Armand Pantalone, our Chief technology Officer, and one other executive. The Severance Agreements are, among other things, designed to avoid the loss of these employees in the event of a potential or following a change of control in our Company. Under Mr. Henckels' agreement, he will receive such salary and other benefits described below for 12 months and acceleration of all unvested equity awards if he is terminated without cause or resigns for good reason, as defined in his Agreement, within 12 months following a change of control. Each would receive 12 months of salary and payment of COBRA premiums following an involuntary termination if made prior to 12 months following a change in control. Under their respective Agreements, Mr. Pantalone and the other executive would be entitled to six months of base salary if either of them resigns for good reason, as defined in his agreement, in connection with a change of control or is terminated without cause, whether or not in connection with a change in control.

 Consummation of the Business Combination on September 8, 2022, constitutes a change of control for this purpose. However, in connection with our entry into the Share Exchange Agreement, each of our then executive officers agreed to waive his right to receive severance benefits under his existing Severance Agreement as a result of a change in his title or responsibilities or reporting structure. In exchange for the waivers, on December 24, 2021, we agreed to grant each of Mr. Regazzi and Mr. Henckels 10 restricted shares of our common stock and each of Mr. Pantalone and the other executive 10,000 restricted shares of our common stock, all of which vested on December 24, 2022.

 In connection with our recent reduction in force, Mr. Pantalone resigned. We agreed to pay him six months severance consistent with our normal payroll practices and subject to his execution of our standard Severance Agreement.

 ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED SHAREHOLDER MATTERS

 The following table includes information as of April 12, 2024, concerning the beneficial ownership of Giga-tronics' common stock for: each person known by Gresham to own beneficially more than 5% of Gresham's outstanding common stock and common stock equivalents; each director and nominee; each executive officer each named in the Summary Compensation Table above; and all directors and executive officers of Gresham as a group.

 The following table is based on 7,931,602 shares of common stock outstanding as of April 8, 2024 Beneficial ownership is determined in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to such securities. Except as otherwise indicated, all persons listed below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. Shares of common stock subject to options or warrants currently exercisable, or exercisable within 60 days and underlying and convertible securities, are deemed outstanding for purposes of computing the percentage ownership of the person holding such option or warrants but are not deemed outstanding

 for purposes of computing the percentage ownership of any other person.. The address of all officers and directors is c/o Gresham Worldwide Incorporated, 7272 E. Indian School Rd, Suite 540, Scottsdale, Arizona 85251.

 ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

 Other than compensation arrangements for our executive officers and directors, we describe below each transaction or series of similar transactions, since January 1, 2022, to which we were a party or will be a party, in which:

 • the amounts involved exceeded or will exceed the lesser of (i) $120,000 or (ii) one percent of the average of our total assets as of the end of our last two fiscal years; and

 • any of our directors, executive officers or holders of more than 5% of our capital stock, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

 On April 21, 2023, each of Messrs. Lutz Henckels, the Company's Chief Financial Officer, and William Horne, a director, advanced $50,000 to the Company as an 8% interest bearing loan to allow the Company to meet its short-term working capital needs. On October 10, 2023 the Company has repaid Mr. Horne with 8% interest and intends to repay Mr. Henckels in 2024.

 Allocation of General Corporate Expenses

 We provide this information using our new December 31 fiscal year we adopted following the Business Combination. AAI provided human resources, accounting, and other services to Gresham Holdings and after September 8th to us. Gresham Holdings obtained its business insurance under AAI's policies. The accompanying financial statements of Gresham Holdings include allocations of these expenses. The allocation method calculates the appropriate share of overhead costs to Gresham Holdings by using Gresham Holdings's revenue as a percentage of total revenue

 of AAI. Gresham Holdings believes the allocation methodology used is reasonable and has been consistently applied, and results in an appropriate allocation of costs incurred. However, these allocations may not be indicative of the cost had Gresham Holdings been a stand-alone entity or of future costs. AAI allocated zero dollars for the year ended December 31, 2023, and $1.09 million for the year ended December 31, 2022.

 Net Transfers From AAI

 Gresham received funding from AAI to cover any shortfalls on operating cash requirements. See Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations– Liquidity and Capital Resources – Our Financings – Our AAI Financings."

 AAI's Historical Bridge Loan to us.

 As our negotiations with Gresham and AAI became serious, in November 2021, an affiliate of AAI loaned us $500,000 (the "Bridge Loan") for general corporate purposes, including operating expenses. We borrowed an additional $300,000 on January 7, 2022 and an additional $500,000 on April 5, 2022, and the outstanding principal amount of the Bridge Loan totaled $1,300,000.

 The promissory note evidencing the Bridge Loan was exchanged for the Exchange Note on December 31, 2022. For information on December 31, 2022 loan transactions with AAI, see Item 7 "Management's Discussion and Analysis of Financial Condition and Results of Operations– Liquidity and Capital Resources – Our Financings – Our AAI Financings."

 AAI's Closing Date Loan to us upon the Closing of the Business Combination

 On September 8, 2022, AAI loaned us $4,250,000 upon the closing of the Business Combination. The loan was evidenced by a convertible note, that was issued to AAI (see Note 14. Notes Payable. Related Parties, net)

 Advances made from AAI to Us and Gresham Holdings

 Through December 31, 2022, AAI advanced Gresham money for working capital purposes in the aggregate amount of $4.6 million. Of this amount, $0.5 million was classified as a capital contribution, and advances previously made by AAI Lending to us in the aggregate amount of $4,067,469 were rolled into a senior secured convertible note on December 31, 2022.

 Interest of Executive Officers and Directors in the Transaction with Giga-tronics

 In connection with the closing of the Business Combination and as required by the Share Exchange Agreement, we repurchased and redeemed outstanding preferred stock (other than the Series F), (the "Outstanding Preferred Shares") at the stated liquidation preference amount of such shares. Our Chief Financial Officer (Lutz Henckels) and one of our directors (Thomas E. Vickers) held some of the Outstanding Preferred Shares that we purchased on the same terms and price as shares of the Outstanding Preferred Shares held by other stockholders. We paid Mr. Henckels $246,000 to redeem his outstanding Preferred Stock and paid Mr. Vickers $116,000 to redeem his outstanding Preferred Stock.

 Severance Agreements

 We had entered into Severance Agreements with each of John Regazzi, our former Chief Executive Officer and a current director; Lutz Henckels, our Chief Financial Officer; Armand Pantalone, our Chief Technology Officer; and one other executive. See "Management". Mr. Pantalone has resigned from the Company on March 1, 2024 and his severance of $137,500 will be paid over a six month period. Mr. Regazzi has extended his debt to be paid in 2025.

 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

 To the Shareholders and Board of Directors of

 Gresham Worldwide, Inc. and Subsidiaries

 Opinion on the Financial Statements

 We have audited the accompanying consolidated balance sheets Gresham Worldwide, Inc. and Subsidiaries, formerly Giga-tronics, Incorporated and Subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations and comprehensive loss, statements of changes in stockholders' equity and cash flows for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the 2 years in the period ended December 31, 2023 in conformity with accounting principles generally accepted in the United States of America.

 We did not audit the December 31, 2023 and 2022 financial statements of Enertec Systems 2001 Ltd., a wholly-owned subsidiary, which statements reflect 51% and 39% of the total consolidated assets as of December 31, 2023 and 2022, respectively, and 41% and 41% of the total consolidated revenues for the years ended December 31, 2023 and 2022, respectively. Those statements were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to the amounts included for Enertec Systems 2001 Ltd., is based solely on the report of other auditors.

 Explanatory Paragraph – Going Concern

 The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 2, the Company has a significant working capital deficiency, has incurred significant losses and needs to raise additional funds to meet its obligations and sustain its operations. These conditions raise substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

 Basis for Opinion

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

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

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

 Critical Audit Matters

 Critical audit matters are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. We determined that there are no critical audit matters.

 As described in Note 2 to the financial statements, the Company recognizes a significant portion of its revenue over time using the cost-to-cost measure of progress, which measures a contract's progress toward completion based on the ratio of actual contract costs incurred to date to the Company's estimated costs at completion. The cost estimation process for these contracts is based on the knowledge and experience of the Company's project managers, engineers, and financial professionals. Changes in job performance, job conditions and management's assessment of expected variable consideration are factors that influence estimates of the total contract transaction price, total costs to complete those contracts and the Company's revenue recognition.

 We identified estimated costs to complete on certain revenue contracts as a critical audit matter. The determination of the total estimated cost and progress toward completion requires management to make significant estimates and assumptions. Total estimated costs to complete projects include various costs such as direct labor, material, and subcontract costs. Changes in these estimates can have a significant impact on the revenue recognized each period. Auditing these estimates involved especially challenging auditor judgment in evaluating the reasonableness of management's assumptions and estimates over the duration of these contracts.

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

 • Examining a sample of revenue contracts to evaluate the appropriateness of the Company's identification of performance obligations and the determination of method for measuring contract progress.

 • Assessing the reasonableness of the estimated costs to complete by selecting a sample of open projects and (i) testing consistency of the estimated total contract costs projected in the current year versus the original or prior period, (ii) assessing the status of completion by testing of a sample of project costs incurred to date and interviewing the Company's management to evaluate progress to date, the estimate of remaining costs to be incurred, and factors impacting the amount of time and cost to complete.

 • Assessing the reasonableness of changes in estimated costs to complete by comparing project profitability estimates in the current period to historical estimates and actual performance and investigating reasons for changes in expected costs and project margins.

 • Evaluating the reasonableness of management's budgeting process by selecting a sample of contract budgets for projects that were completed during the period and performing a retrospective review of budget to actual variances.

 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

 Note 1. Description of Business
 Gresham Worldwide, Inc., ("Gresham" or the "Company") designs, manufactures and distributes purpose-built electronics equipment, automated test solutions, power electronics, supply and distribution solutions, as well as radio, microwave and millimeter wave communication systems and components for a variety of applications with a focus on the global defense industry and the healthcare market.
 Gresham was established by the Business Combination of Giga-tronics and Gresham Holdings, and is led by Jonathan Read, its Chief Executive Officer, Robin Shaffer, its Chief Operating Officer, and Lutz Henckels, its Chief Financial Officer.
 Our operations consist of three reporting segments:
 • Radio Frequency Solutions ("RF Solutions") – consists of Microphase which is located in Connecticut. Microphase designs and manufactures custom microwave hardware products for military applications and generates revenue primarily through production contracts for custom engineered components and RADAR filters.

 • Precision Electronic Solutions – consists of one subsidiary and one division, namely Enertec located in Israel and what we call our legacy Giga-tronics business. Enertec develops and supplies advanced command & control, test and calibration systems for use in failsafe military and medical applications. The legacy business of Giga-tronics (the "Giga-tronics Business") consists of Microsource, a wholly-owned subsidiary which develops and manufactures sophisticated RADAR filters used in fighter aircraft, and "EW Test and Training", which serves the defense electronics market with a signal generation platform. We refer to this later business as our "Giga-tronics Division".

 • Power Electronics & Displays – consists of two subsidiaries, namely Gresham Power and Relec located in the United Kingdom (the "UK") which primarily engineer and provide integrated, mobile power electronics and display solutions that distribute and supply continuous, dependable, clean low voltage power.

 Note 2. Going Concern and Management's Plan
 The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. The Company has incurred recurring net losses and operations have not provided cash flows. In view of these matters, there is substantial doubt about our ability to continue as a going concern. The Company intends to finance its future development activities and its working capital needs largely through the sale of equity securities with some additional funding from other sources, including term notes until such time as funds provided by operations are sufficient to fund working capital requirements.
 The consolidated financial statements of the Company do not include any adjustments relating to the recoverability and classification of recorded assets, or the amounts and classifications of liabilities that might be necessary should the Company be unable to continue as a going concern.

 Note 3. Basis of Presentation and Summary of Significant Accounting Policies
 Basis of Presentation
 The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America ("GAAP").

 Accounting Estimates
 The preparation of financial statements, in conformity with GAAP, requires management to make estimates, judgments and assumptions. The Company's management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Significant estimates in these financial statements include revenue recognition, the estimated useful lives of property and equipment and intangible assets, fair value of convertible notes, fair values of assets acquired and liabilities assumed in business combinations, impairment of goodwill and long-lived assets and accounting for lease obligations and income tax uncertainties and contingencies.

 Principles of Consolidation
 The consolidated financial statements include the accounts of Gresham Worldwide and its wholly owned and majority-owned subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation.

 Reclassifications
 Certain prior year amounts have been reclassified for comparative purposes to conform to the current-year financial statement presentation. Accounts payable and accrued expenses and Other current liabilities have been reclassified as Accounts payable and accrued expenses, Deferred

 revenue and Other current liabilities. These reclassifications had no effect on previously reported results of operations. The impact on any prior period disclosures was immaterial.

 Significant Accounting Policies
 Business Combinations
 The Company allocates the purchase price of an acquired business to the tangible and intangible assets acquired and liabilities assumed based upon their estimated fair values on the acquisition date. Any excess of the purchase price over the fair value of the net assets acquired is recorded as goodwill. Acquired customer relations, developed technology and tradenames are recognized at fair value. The purchase price allocation process requires management to make significant estimates and assumptions as of the acquisition date with respect to intangible assets. The allocation of the consideration transferred in certain cases may be subject to revision based on the final determination of fair values during the measurement period, which may be up to one year from the acquisition date. The Company includes the results of operations of the business that it has acquired in its consolidated results prospectively from date of acquisition. Direct transaction costs associated with the business combination are expensed as incurred.

 Revenue Recognition
 The Company recognizes revenue in accordance with Financial Accounting Standards Board ("FASB") issued Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers ("ASC 606"). The core principle of ASC 606 is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle:
 • Step 1: Identify the contract with the customer,

 • Step 2: Identify the performance obligations in the contract,

 • Step 3: Determine the transaction price,

 • Step 4: Allocate the transaction price to the performance obligations in the contract, and

 • Step 5: Recognize revenue when the company satisfies a performance obligation.

 Sales of Products
 The Company enters into contracts directly with its customers and generates revenues from the sale of its products through a direct and indirect sales force. The Company's performance obligations to deliver products are satisfied at the point in time when products are received by the customer, which is when the customer obtains control over the goods. The Company provides standard assurance warranties, which are not separately priced, that the products function as intended. The Company primarily receives fixed consideration for sales of product. Some of the Company's contracts with distributors include stock rotation rights after six months for slow moving inventory, which represents variable consideration. The Company uses an expected value method to estimate variable consideration and constrains revenue for estimated stock rotations until it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur. To date, returns have been insignificant.
 Because the Company's product sales agreements have an expected duration of one year or less, the Company has elected to adopt the practical expedient in ASC606-10-50-14(a) of not disclosing information about its remaining performance obligations.
 Manufacturing Services
 The Company's principal business is providing manufacturing services in exchange primarily for fixed fees. The Company's performance obligation for manufacturing services is satisfied over time as the Company creates or enhances an asset based on criteria that are unique to the customer and that the customer controls as the asset is created or enhanced. Generally, the Company recognizes revenue based upon proportional performance over time using a cost-to-cost method which measures progress based on the costs incurred to total expected costs in satisfying its performance obligation. This method provides a depiction of the progress in providing the manufacturing service because there is a direct relationship between the costs incurred by the Company and the transfer of the manufacturing service to the customer. Manufacturing services are recognized based upon the proportional performance method as services transferred over time and to the extent the customer has not been invoiced for these revenues, as accrued revenue in the accompanying consolidated balance sheets. Revisions to the Company's estimates may result in increases or decreases to revenues and income and are reflected in the consolidated financial statements in the periods in which they are first identified.
 The Company has elected the practical expedient in ASC 606-10-50-14(a) to not adjust the promised amount of consideration for the effects of a significant financing component to the extent that the period between when the Company transfers its promised good or service to the customer and when the customer pays in one year or less.

 Accounts Receivable and Allowance for Doubtful Accounts
 The Company's receivables are recorded when billed and represent claims against third parties that will be settled in cash. The carrying amount of the Company's receivables, net of the allowance for doubtful accounts, represents their estimated net realizable value. The Company

 individually reviews all accounts receivable balances and based upon an assessment of current creditworthiness, estimates the portion, if any, of the balance that will not be collected. The Company estimates the allowance for doubtful accounts based on historical collection trends, age of outstanding receivables and existing economic conditions. If events or changes in circumstances indicate that a specific receivable balance may be impaired, further consideration is given to the collectability of those balances and the allowance is adjusted accordingly. A customer's receivable balance is considered past-due based on its contractual terms. Past-due receivable balances are written-off when the Company's internal collection efforts have been unsuccessful in collecting the amount due.
 Based on an assessment of the collectability of accounts receivable as of December 31, 2023 and 2022, an allowance was provided for doubtful accounts of $ 56,000 and $ 64,000, respectively.

 Accrued Revenue
 Manufacturing services that are recognized as revenue based upon the proportional performance method are considered revenue based on services transferred over time and to the extent the customer has not been invoiced for these revenues, are recorded as accrued revenue in the accompanying consolidated balance sheets.

 Fair value of Financial Instruments
 In accordance with ASC No. 820, Fair Value Measurements and Disclosures, fair value is defined as the exit price, or the amount that would be received for the sale of an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date.
 The guidance also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs include those that market participants would use in valuing the asset or liability and are developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company's assumptions about the factors that market participants would use in valuing the asset or liability. The guidance establishes three levels of inputs that may be used to measure fair value:
 Level 1: Quoted market prices in active markets for identical assets or liabilities.
 Level 2: Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or model-derived valuations. All significant inputs used in our valuations are observable or can be derived principally from or corroborated with observable market data for substantially the full term of the assets or liabilities. Level 2 inputs also include quoted prices that were adjusted for security-specific restrictions which are compared to output from internally developed models such as a discounted cash flow model.
 Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
 The carrying amounts of financial instruments carried at cost, including cash and cash equivalents and accounts receivables, approximate their fair value due to the short-term maturities of such instruments. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

 Foreign Currency Translation
 Assets and liabilities recorded in foreign currencies are translated at the exchange rate on the balance sheet date. Revenue and expenses are translated at average rates of exchange prevailing during the year. Translation adjustments resulting from this process are recorded to other comprehensive income.

 Cash and Restricted Cash
 Cash is maintained in checking accounts, money market funds and certificates of deposits with reputable financial institutions in banks in the United States ("U.S."), United Kingdom ("UK") and Israel. Such deposits in the U.S. may exceed the U.S. Federal Deposit Insurance

 Inventories
 Inventories are stated at the lower of cost or net realizable value. Cost of inventories is determined as follows:
 • Raw materials, parts and supplies—using the "first-in, first-out" method.

 • Work-in-progress and finished products—using the "first-in, first-out" method on the basis of direct manufacturing costs with the addition of indirect manufacturing costs.

 The Company periodically assesses its inventories valuation in respect of obsolete items by reviewing revenue forecasts and technological obsolescence and moving such items into a reserve allowance for obsolescence. When inventories on hand exceed the foreseeable demand or become obsolete, the value of excess inventory, which at the time of the review was not expected to be sold, is written off.

 Property and Equipment, Net
 We record property and equipment at cost, less accumulated depreciation. Acquisitions and improvements are capitalized, and maintenance and repairs are expensed as incurred. As we dispose of assets, we remove the cost and related accumulated depreciation from the accounts, and any

 resulting gain or loss is included within loss on disposal or impairment of assets, net. Depreciation expense is calculated using the straight-line method over the estimated useful lives of the assets, at the following rates:

 Assets

 Useful Lives (In Years)

 Computer software and office and computer equipment

 3 - 5

 Machinery and equipment, automobile, furniture and fixtures

 5 - 10

 Leasehold improvements

 Over the term of the lease or life of the asset, whichever is shorter

 Goodwill and Indefinite-Lived Intangible Assets
 Goodwill and indefinite-lived intangible assets are not amortized but are assessed annually for impairment as of December 31, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit or the fair value of an indefinite-lived intangible asset below its carrying value.
 Goodwill represents the excess purchase price over the fair value of the net assets acquired. When conducting annual or interim impairment assessments, if applicable, a two-step process is used. First, an optional qualitative evaluation is performed as to whether it is more likely than not that the fair value of the Company's each reporting unit is less than its carrying value, using an assessment of relevant events and circumstances. In performing this assessment, the Company is required to make assumptions and judgments including, but not limited to, an evaluation of macroeconomic conditions as they relate to the business, industry and market trends, as well as the overall future financial performance of the reporting unit.
 If it is determined that it is not more likely than not that the fair value of the reporting unit is less than its carrying value, no additional tests are performed. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, the Company performs a second step consisting of a quantitative assessment of goodwill impairment.
 This assessment requires the Company to compare the fair value of its reporting unit with its carrying value. If the carrying amount exceeds the fair value, an impairment charge will be recognized. In performing this assessment, the Company is required to make assumptions and judgments including, but not limited to, financial projections, discount rate, and future market conditions.
 For indefinite-lived intangible assets with indefinite lives, the Company has the option to first assess qualitative factors of the indefinite-lived intangible assets. If the result of a qualitative test indicates that it is more likely that not that the asset is impaired a quantitative test is performed. When a quantitative test is performed, the estimated fair value of an asset is compared to its carrying value. If the carrying value of such asset exceeds its estimated fair value, an impairment charge is recorded for the difference between the carrying value and the estimated fair value.

 Intangible Assets
 The Company records intangible assets subject to amortization at fair value at the date of acquisition. The Company has trademarks which were determined to have an indefinite life. Intangibles with definite lives consist of Customer relationships, which are amortized on a straight line bases over their estimated useful lives from 10 - 14 years.
 The Company reviews intangible assets for impairment whenever events or changes in business circumstances indicate that the carrying amount of the assets might not be recoverable. The factors that the Company considers in deciding when to perform an impairment review include significant underperformance of the business in relation to expectations, significant negative industry or economic trends, and significant changes or planned changes in the use of the assets. When an impairment review is performed to evaluate a long-lived asset for recoverability, the Company compares forecasts of undiscounted cash flows expected to result from the use and eventual disposition of the long-lived asset to its carrying value. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of an asset are less than its carrying amount. The impairment loss would be based on the excess of the carrying value of the impaired asset over its fair value, determined based on discounted cash flows.

 Long-Lived Assets
 The long-lived assets of the Company are reviewed for impairment in accordance with ASC 360, Property, Plant, and Equipment, whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

 Management reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to undiscounted expected future cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by comparing the amount by which the carrying amount of the assets to their fair value.
 Fair value option

 The Company has elected to record the Senior Secured Convertible Notes and Senior Secured Convertible Notes Payable, Related Parties (together "Convertible Notes") at fair value on the date of issuance, with gains and losses arising from changes in fair value recognized in the consolidated statements of operations at each period end while those are outstanding. Issuance costs are recognized in the consolidated statement of operations in the period in which they are incurred. The fair value of the Convertible Notes were determined using a probability weighted expected return model ("PWERM"), a scenario-based valuation model in which discrete future outcome scenarios for the Company are projected and discounted to present value.
 The Company assesses the inputs used to measure fair value using the three-tier hierarchy based on the extent to which inputs used in measuring fair value are observable in the market. For instruments where little or no public market exists, management's determination of fair value is based on the best available information which may incorporate management's own assumptions and involves a significant degree of judgment, taking into consideration various factors including earnings history, financial condition, recent sales prices of the issuer's securities and liquidity risks.

 Warranty
 The Company offers a warranty period of 12 months for all its manufactured products. The Company estimates the costs that may be incurred under its warranty and records a warranty liability in the amount of such costs at the time product revenue is recognized. Factors that affect the Company's warranty liability include the number of units sold, historical rates of warranty claims and cost per claim. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the amount, as necessary.

 Contingencies
 The Company is periodically involved in litigation arising from other matters in the ordinary course of business. The Company can be subject to claims, suits, regulatory and government investigations, and other proceedings involving labor and employment, commercial disputes, and other matters. Such claims, suits, regulatory and government investigations, and other proceedings could result in fines, civil penalties, or other adverse consequences.
 Certain of these outstanding matters include speculative, substantial or indeterminate monetary amounts. The Company records a liability when it believes that it is probable that a loss has been incurred and the amount can be reasonably estimated. If the Company determines that a loss is reasonably possible and the loss or range of loss can be estimated, the Company discloses the range of loss. The Company evaluates developments in its legal matters that could affect the amount of liability that has been previously accrued, and the matters and related reasonably possible losses disclosed, and makes adjustments as appropriate. Significant judgment is required to determine both likelihood of there being and the estimated amount of a loss related to such matters.

 Income Taxes
 The Company determines its income taxes under the asset and liability method in accordance with FASB ("ASC No. 740"), Income Taxes, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are based on the differences between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the fiscal year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance to the extent management concludes it is more likely than not that the assets will not be realized. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the fiscal years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the Consolidated Statements of Operations and Comprehensive Loss in the period that includes the enactment date.
 The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit to be recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. To the extent that the final tax outcome of these matters is different than the amount recorded, such differences impact income tax expense in the period in which such determination is made. Interest and penalties, if any, related to accrued liabilities for potential tax assessments are included in income tax expense. ASC No. 740 also requires management to evaluate tax positions taken by the Company and recognize a liability if the Company has taken uncertain tax positions that more likely than not would not be sustained upon examination by applicable taxing authorities.
 As of December 31, 2023, the Company's gross liability for uncertain tax positions, including interest and penalties, was $ 30,000. As of December 31, 2022, there are no uncertain tax positions taken, that would require recognition of a liability that would require disclosure in the financial statements.

 Stock-Based Compensation
 The Company accounts for stock-based compensation in accordance with ASC 718, Compensation – Stock Compensation ("ASC 718"). The Company uses the Black-Scholes option pricing model for determining the estimated fair value for stock-based awards. The Black-Scholes model requires the use of assumptions which determine the fair value of stock-based awards, including the option's expected term and the price volatility of the underlying stock. Forfeitures are accounted for as they occur.
 The Company recognizes stock-based expenses related to stock option awards on a straight-line basis over the requisite service period of the awards, which is generally the vesting term. The Company calculates the expected term utilizing the simplified method which is the average

 between the various vesting period and contractual term. The Company determines the volatility of its stock by looking at the historic volatility of its stock over the expected term of the stock options, and the risk-free rate reflects the U.S. Treasury yield for a similar expected life instrument in effect at the time of the grant.

 Concentration of Credit Risk
 Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and trade receivables.
 Trade receivables of the Company and its subsidiaries are mainly derived from sales to customers located primarily in the U.S., Europe and Israel. The Company performs ongoing credit evaluations of its customers and to date has not experienced any material losses. An allowance for doubtful accounts is determined with respect to those amounts that the Company have determined to be doubtful of collection.

 Net Loss per Share

 Basic net loss per common share is computed using the weighted average number of common shares outstanding during the period. Diluted Earnings per Share ("EPS") incorporates the incremental shares issuable upon the assumed exercise of stock options and warrants using the treasury stock method. Anti-dilutive securities are not included in the computation of diluted EPS.
 Comprehensive Loss
 The Company reports comprehensive loss in accordance with ASC 220, Comprehensive Income. This statement establishes standards for the reporting and presentation of comprehensive loss and its components in a full set of general purpose financial statements. Comprehensive loss generally represents all changes in equity during the period except those resulting from investments by, or distributions to, stockholders.

 Leases
 The Company accounts for its leases under ASC 842, Leases. Under this guidance, arrangements meeting the definition of a lease are classified as operating or financing leases. Operating leases are recognized as Right-of-use ("ROU") assets, Operating lease liability, current, and Operating lease liability, non-current on our consolidated balance sheets. Lease assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. In certain of our lease agreements, we receive rent holidays and other incentives. We recognize lease costs on a straight-line basis over the lease term without regard to deferred payment terms, such as rent holidays, that defer the commencement date of required payments. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Leasehold improvements are capitalized at cost and amortized over the lesser of their expected useful life or the remaining life of the lease, without assuming renewal features, if any, are exercised. We elected the practical expedient in ASC 842 and do not separate lease and non-lease components for our leases.

 Recent Accounting Standards Adopted
 In June 2016, the FASB issued ASU No. 2016-13, "Financial Instruments—Credit Losses", ("ASU No. 2016-13") to improve information on credit losses for financial assets and net investment in leases that are not accounted for at fair value through net income. ASU 2016-13 replaces the current incurred loss impairment methodology with a methodology that reflects expected credit losses. This guidance is effective for the Company beginning on January 1, 2023, with early adoption permitted. The Company adopted the guidance on January 1, 2023, and has concluded that the adoption did no t have a material impact on its consolidated financial statements.
 In October 2021, the FASB issued ASU 2021-08, "Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers," which requires contract assets and contract liabilities acquired in a business combination to be recognized and measured by the acquirer on the acquisition date in accordance with ASC 606, "Revenue from Contracts with Customers." The guidance will result in the acquirer recognizing contract assets and contract liabilities at the same amounts recorded by the acquiree. The guidance should be applied prospectively to acquisitions occurring on or after the effective date. The Company adopted the guidance on January 1, 2023, and has concluded that the adoption did no t have a material impact on its consolidated financial statements.
 In January 2017, FASB issued Accounting Standards Update (ASU) 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminated the calculation of implied goodwill fair value. Instead, companies will record an impairment charge based on the excess of a reporting unit's carrying amount of goodwill over its fair value. This guidance is effective for the Company beginning on January 1, 2023, with early adoption permitted. The Company has not elected to early adopt the provisions of ASU 2017-04. If early adoption had been selected, the goodwill impairment recorded and analysis performed at December 31, 2022 would have been materially different given that one of the reporting units had negative carrying value. The Company adopted the guidance on January 1, 2023, and has concluded that the adoption did no t have a material impact on its consolidated financial statements.
 In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, ("ASU 2023-09"), which requires disclosure of incremental income tax information within the rate reconciliation and expanded disclosures of income taxes paid, among other disclosure requirements. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company's management does not believe the adoption of ASU 2023-09 will have a material impact on its financial statements and disclosures.

 Note 7. Business Combination
 On September 8, 2022, Gresham acquired 100 % of the capital stock of Gresham Holdings from AAI in exchange for 2.92 million shares of our common stock and 514.8 shares of our Series F preferred that are convertible into an aggregate of 3.96 million shares of our common stock. Gresham also assumed Gresham Holdings' outstanding equity awards representing the right to receive up to 749,626 shares of our common stock, on an as-converted basis. The transaction described above resulted in a change of control of the Company. Assuming AAI was to convert all of the Series F, it would own approximately 69.6 % of Gresham' outstanding shares. The Series F Certificate of Determination contains an exchange cap which requires Gresham's shareholders to approve the issuance of more than 19.99 % of Gresham's outstanding common stock that would apply as of the time of any future conversion (the "Exchange Cap"). On September 8, 2022 the Company's shareholders approved issuances of its common stock upon conversion of the Series F in excess of the Exchange Cap.
 We acquired Gresham Holdings to drive growth, both organically and through strategic combinations with providers of bespoke technology solutions for defense customers, expand our presence in the U.S. defense market by adding strong management, innovative technology, and more engineering resources and to unlock synergies across operating subsidiaries.
 On September 8, 2022, AAI loaned Gresham $ 4.2 million by purchasing a convertible note that carries an interest rate of 10 % per annum and matures on February 14, 2023. This note was exchanged for what was called an Exchange Note on December 31, 2022 as described in Note 14. Notes Payable, Related Parties, net.
 In respect of the above transactions, the acquired assets and assumed liabilities, together with acquired processes and employees, represent a business as defined in ASC 805, Business Combinations. The transactions were accounted for as a reverse acquisition using the acquisition method of accounting with Gresham treated as the legal acquirer and Gresham Holdings treated as the accounting acquirer. In identifying GWW as the acquiring entity for accounting purposes, Gresham and Gresham Holdings took into account a number of factors, including the relative voting rights, executive management and the corporate governance structure of the Company. Gresham Holdings is considered the accounting acquirer since AAI received control of the board of directors of Gresham following the transaction and acquired a 69.6 % beneficial ownership interest of Gresham. However, no single factor was the sole determinant in the overall conclusion that Gresham Holdings is the acquirer for accounting purposes; rather all relevant factors were considered in arriving at such conclusion.
 The fair value of the purchase consideration is $ 8.2 million, consisting of $ 4.1 million for our common stock and warrants, $ 0.3 million fair value of vested stock incentives and $ 3.8 million for cash consideration paid to our then existing preferred stockholders to redeem outstanding preferred stock.
 The Company estimated the fair values of assets acquired and liabilities assumed using valuation techniques, such as the income, cost and market approaches. The fair values are based on available historical information and on future expectations and assumptions deemed reasonable by management but are inherently uncertain. The income method to measure the fair value of intangible assets, is based on forecasts of the expected future cash flows attributable to the respective assets. Significant estimates and assumptions inherent in the valuations reflected a consideration of other marketplace participants and included the amount and timing of future cash flows (including expected growth rates and profitability), the underlying product or technology life cycles, economic barriers to entry and the discount rate applied to the cash flows. Unanticipated market or macroeconomic events and circumstances could affect the accuracy or validity of the estimates and assumptions.
 We allocate the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values at the date of the business combination. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require us to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, estimated replacement costs and future expected cash flows from acquired customers, acquired technology, acquired patents, and trade names from a market participant perspective, useful lives and discount rates. The estimates of fair value are based upon assumptions believed to be reasonable, but

 which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Allocation of purchase consideration to identifiable assets and liabilities affects our amortization expense, as acquired finite-lived intangible assets are amortized over their useful life, whereas any indefinite lived intangible assets, including trademark and goodwill, are not amortized. During the measurement period, which is not to exceed one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. During the three months ended December 31, 2022, the measurement period adjustment increased the preliminary allocation of goodwill by $ 9.2 million due to revised forecasts resulting from the lack of sales and backlog, with the offset to trademark, developed technologies, customer lists, inventory and other assets by $ 1.0 million, $ 1.4 million, $ 3.9 million, $ 2.7 million and $ 0.2 million respectively.

 The Company tests goodwill for impairment at the reporting unit level annually on December 31 or more frequently if there are indicators that the carrying amount of the goodwill exceeds its estimated fair value.
 Giga-tronics
 The legacy Giga-tronics reporting unit (consisting of what we call the Giga-tronics Division and Microsource) experienced a significant decline in sale during the fourth quarter of 2022 and is projecting a negative growth rate due to customers scaling back on programs, a lack of backlog, a highly competitive industry and certain operational challenges that have affected our expectations such that future growth and profitability is significantly lower than previous estimates. Furthermore, during the fourth quarter of 2022, the Company's market capitalization declined steadily which, although not a determinant on its own, when combined with the other factors indicated that the Giga-tronics reporting unit goodwill was determined to be impaired.
 Because the qualitative test indicated that Giga-tronics reporting unit goodwill was determined to be impaired a second phase of the goodwill impairment test ("Step 2") was performed specific to Giga-tronics reporting unit. Under Step 2, the fair value of the reporting unit was estimated for the purpose of deriving an estimate of the implied fair value of goodwill. The implied fair value of the goodwill was then compared to the recorded goodwill to determine the amount of the impairment. The Company utilized an enterprise value-based income approach to determine the fair value of the reporting unit. The income approach discounts projected free cashflows of the reporting unit at a computed weighted average cost of capital of 17.5 % as the discount rate. The income approach requires the use of significant estimates and assumptions, which include a zero revenue growth assumption and negative future operating margins used to calculate projected future cashflows, weighted average cost of capital, and future economic and market conditions. The Company bases the forecasts on its knowledge of the industry, recent performance and expected future performance of the reporting unit, and other assumptions management believes to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates.

 As a result, the entire goodwill carrying amount of Giga-tronics reporting unit was recognized as an impairment charge during the year ended December 31, 2022.
 Microphase
 During the fourth quarter of 2023, Microphase reporting unit experienced a significant decline in sales and annually continues to have operating losses.
 Due to these factors, we determined that a triggering event had occurred, and therefore, performed a quantitative goodwill impairment assessment as of December 31, 2023. Under quantitative testing, the fair value of the reporting unit was estimated for the purpose of deriving an estimate of the implied fair value of goodwill. The implied fair value of the goodwill was then compared to the recorded goodwill to determine the amount of the impairment. The Company utilized an enterprise value-based income approach to determine the fair value of the reporting unit. The income approach requires the use of significant estimates and assumptions, which include a zero revenue growth assumption and negative future operating margins used to calculate projected future cashflows, weighted average cost of capital, and future economic and market conditions. The Company bases the forecasts on its knowledge of the industry, recent performance and expected future performance of the reporting unit, and other assumptions management believes to be reasonable but that are unpredictable and inherently uncertain. Actual future results may differ from those estimates.
 The results of the quantitative test indicated the fair value of the Microphase reporting unit did not exceed its carrying amounts, including goodwill, in excess of the carrying value of the goodwill. As a result, the entire $ 3.2 million carrying amount of Microphase's goodwill was recognized as a impairment charge during the year ended December 31, 2023. There were no impairments of goodwill during the year ended December 31, 2022.
 Enertec, Relec
 For Enertec and Relec reporting units, the Company has determined that the reporting units benefit from a continued positive forecast within the industry, a significant backlog of contracted work, a history of and/or projected positive earnings and have not experience any technological, market or operational circumstances which indicate that the carrying values of reporting units goodwill may not be recoverable. Based on the qualitative assessment, it was concluded that it is not more likely than not that the fair value of the reporting units is less than its carrying amount. Management concluded that no quantitative testing was needed as it was not more likely than not that reporting units fair value are less than its carrying value as of December 31, 2023.

 The Notes accrue interest at a rate of 7 % per annum payable monthly, which increased to 18 % upon the event of default as of December 31, 2023. Due to the default the Company is required to pay 20 % of consolidated revenues monthly on each interest payment date in reduction of

 the principal amount. In addition, the holders have the right to require us to prepay the Convertible Notes at a 125 % of principal. Further, upon a bankruptcy event of default or a change of control event amounts owed would be 125 % of the principal remaining.

 Security and Restrictive Covenants
 The Convertible Notes are secured by the assets of the Company pursuant to a Security Agreement entered into for such purpose, and are senior to the indebtedness payable to AAI, pursuant to a subordination agreement entered into in connection with the SPA.
 The Convertible Notes contain customary restrictive covenants including covenants against incurring new indebtedness or liens, changing the nature of its business, transfers of assets, transactions with affiliates, and issuances of securities, subject to certain exceptions and limitations.
 The Convertible Notes have a working capital covenant pursuant to which the Company's working capital, excluding any debt owed to AAI Lending or any of its affiliates and the modified Notes, shall increase from the Company's working capital as of September 30, 2023, by a minimum of $ 250,000 per quarter for the quarters ending December 31, 2023 and March 31, 2024 and $ 500,000 per quarter thereafter while either of the modified Notes remain outstanding.

 Conversion Features
 The Convertible Notes are convertible at a conversion price equal to the greater of (a) 90 % of the VWAP for the 10 trading days prior to the conversion date and (b) $ 0.25 per share, subject to adjustment including downward adjustment upon any dilutive issuance of securities.

 Fair Value
 The Company elected the fair value option with respect to the Convertible Notes. The fair value of the liability was determined based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The Company used the probability-weighted expected return method ("PWERM") to arrive at a fair value. This approach involved the estimation of future potential outcomes for the Convertible Notes, as well as values and probabilities associated with each respective potential outcome.
 The Company arrived at the fair value of the Notes liability as shown below:

 Senior Secured Convertible Note, As Amended
 Fiscal 2022
 During 2022 the Company entered into Senior Secured Convertible Notes, as amended with AAI by which the Company received a total of $ 12.0 million. The notes bear interest at 10 % per annum and are due on January 15, 2025 except for a $ 1.0 million note which bears a 12 % interest and is due on June 15, 2025.
 At the option of AAI, the notes are convertible into the Company's common stock at a conversion price equal to the lesser of (i) $ 0.78 per share, or (ii) the VWAP Price on such date less a 20 % discount to such VWAP Price, but in no event less than $ 0.25 per share. In addition, all principal and outstanding interest under the Exchange Note will automatically convert to the Company's common stock upon (i) the consummation of a public offering of securities in which the Company receives net proceeds (net of underwriters' discounts and selling commissions) of at least $ 25 million ("Qualified Public Offering" scenario), in which case the conversion price shall be the price at which the Common Stock is sold to the public, provided, however, that no underwriters' discounts or selling commissions shall be imposed on such conversion, (ii) the consummation of a private or public offering of shares of Common Stock that is not a Qualified Public Offering but that results in the net proceeds (net of underwriters' discounts and selling commissions) to the Company of at least $ 5 million ("Non-qualified Offering" scenario), in which case the conversion price shall be the price at which Common Stock is sold in such Non-Qualified Offering less a twenty-five percent ( 25 %) discount or (iii) December 31, 2024, in which case the conversion price shall be the VWAP Price less a 25 % discount to such VWAP Price.
 With a limited exception, the Secured Note contains a most favored nations provision with respect to future financings of the Company. With limited exceptions, the Company also agreed to certain negative covenants that will require the prior approval of the holder of the Secured Note to incur indebtedness (other than permitted indebtedness), enter into variable rate transactions, incur indebtedness for borrowed money, purchase money indebtedness or lease obligations that would be required to be capitalized on a balance sheet prepared in accordance with U.S. Generally Accepted Accounting Principles, or guaranty the obligations of any other person, in an aggregate amount at any time outstanding in excess of $ 1,000,000 in any individual transaction or $ 2,500,000 in the aggregate.
 The Company's obligations under the Purchase Agreement and the Secured Note are secured by a lien on all of the assets of the Company and its wholly owned subsidiaries pursuant to a Security Agreement.
 Fiscal 2023
 On October 11, 2023, the Company and AAI entered into an agreement pursuant to which the maturity date was extended to January 15, 2025 ("Held to Maturity" scenario) and the indebtedness is now subordinate to the Convertible Notes (see Note 13. Senior Secured Convertible Notes and Warrants).

 Allocation of General Corporate Expenses
 AAI provided human resources, accounting, and other services to Gresham Holdings. The accompanying financial statements of Gresham Holdings include allocations of these expenses prior to the Business Combination. The allocation method calculates the appropriate share of overhead costs to Gresham Holdings by using Gresham Holdings's revenue as a percentage of total revenue of AAI. Gresham Holdings believes the allocation methodology used is reasonable and has been consistently applied, and results in an appropriate allocation of costs incurred. However, these allocations may not be indicative of the cost had Gresham Holdings been a stand-alone entity or of future costs.

 On July 1, 2022, Gresham Holdings acquired an additional 444,444 newly issued shares of Microphase to increase its ownership interest in Microphase from 55 % to 63 % in exchange for consideration of $ 1 million.

 Note 18. Stockholder's Equity
 Amendments to Certificate of Incorporation
 On September 22, 2022, the Company amended the Articles of Incorporation to increase the number of shares the Company is authorized to issue to 101,000,000 shares by increasing the number of authorized shares of common stock from 13,333,333 shares to 100,000,000 shares.
 Preferred Stock
 The Company is authorized to issue 1,000,000 shares of Preferred Stock with no par value.
 The Company had authorized Series A convertible preferred stock of 250,000. No shares are issued and outstanding.
 The Company had issued series B through E preferred stock which were redeemed with the Business Combination (See Note 7. Business Combination).
 On September 8, 2022, the Company issued AAI, as part of the consideration for the acquisition of Gresham Holdings, 514.8 shares of Series F preferred stock. The terms, preferences and rights of holders of the Series F are set forth in the Certificate of Determination which was filed with the California Secretary of State, on August 23, 2022.
 Seniority and Liquidation Preference
 The Series F ranks senior to the shares of the Company's common stock with respect to dividend rights and rights on the distribution of assets on any liquidation, dissolution or winding up of its affairs. The Series F has a liquidation preference of $ 25,000 per share. The 514.8 shares of Series F have an aggregate liquidation preference of $ 12.9 million.
 Conversion Right
 The shares of Series F are convertible into the Company's common stock at the holder's option at a conversion price of $ 3.25 per share, subject to customary adjustments for stock splits (including the reverse split). The 514.8 shares of Series F that were issued to AAI upon the consummation of the transactions contemplated by the Agreement are convertible into an aggregate of 3,960,043 shares of the Company's common stock. If converted in a public offering of the Company's stock, the conversion price will be at the public offering price less underwriting discounts and commissions.
 Dividend Rights
 The holders of Series F are entitled to participate with the Company's common stock and receive such dividends and distributions as they would receive if their shares of Series F are converted to common stock. The Company may not pay dividends without the consent of the holders of the Series F. Holders of Series F are also entitled to such dividends as the Board may declare on shares from time to time, if any.
 Voting Rights; Board Representation

 Holders of Series F have the right to vote on matters submitted to a vote of the holders of common stock on an as-converted basis unless required by applicable law. In addition, holders of Series F are entitled to elect four of the Company's seven directors. Upon the closing of the Business Combination, AAI exercised its right adding four directors to our board of directors including our Chief Executive Officer and three persons who are AAI directors.
 Approval Rights for Certain Matters
 For so long as AAI consolidates the Company as a subsidiary of AAI for financial reporting purposes, the Company will require prior approval of the holders of the Series F to incur indebtedness in excess of $ 1 million per individual transaction or $ 2.5 million in the aggregate or to complete a merger, acquisition or purchase of assets where the aggregate consideration is valued at more than $ 1 million. Holders of the Series F have separate class approval rights over certain specified actions that would affect the rights of holders of the Series F (see Note 24. Subsequent Events).
 Preemptive/Participation Rights
 If the Company sells any voting stock, or securities representing the right to acquire its voting stock, holders of Series F have the right to purchase, at the same price as other participants in the offering, a pro rata portion of such securities based on their aggregate voting power held such that they may maintain the percentage of voting power held. This participation right does not apply to certain exercises and conversions of outstanding securities, certain issuances pursuant to equity incentive plans and certain public offerings of the Company's common stock of $ 25 million or more. This participation right terminates upon the earlier of the date that holders of Series F cease to beneficially own at least 50 % of the Company's common stock or September 8, 2027.
 Common Stock
 Common stock confers upon the holders the rights to receive notice to participate and vote at any meeting of stockholders of the Company, to receive dividends, if and when declared, and to participate in a distribution of any surplus of assets upon liquidation of the Company.

 ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is "more likely than not." Realization of the future tax benefits is dependent on the Company's ability to generate sufficient taxable income within the carryforward period. Because of the Company's recent history of operating losses, management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits is currently not likely to be realized and, accordingly, has provided a valuation allowance. The valuation allowance increased by $ 2.5 million and $ 6.8 million for the year ended December 31, 2023 and 2022, respectively.

 In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the Tax Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The Company elected to treat any potential GILTI inclusions as a period cost.

 The Company is subject to tax in the U.S., U.K. and Israel and is subject to audit by tax authorities in the U.S., U.K. and Israel for which returns are subject to examination for various years dependent on the jurisdiction.

 Note 20. Net Loss Per Share
 Basic net loss per share is computed by dividing net loss by weighted average number of common shares outstanding for the period (excluding outstanding stock options). Diluted net loss per share is computed using the weighted-average number of common shares outstanding for the period plus the potential effect of dilutive securities which are convertible into common shares (using the treasury stock method), except in cases in which the effect would be anti-dilutive. The following is a reconciliation of the numerators and denominators used in computing basic and diluted net loss per share:
