The board of directors of each of the Company and the Buyer unanimously approved the Purchase Agreement and the transactions contemplated thereby (collectively, the “Transaction”“Microlab Transaction”). On February 25, 2022, the shareholders of the Company approved the transactionMicrolab Transaction at a Special Meeting of Shareholders held virtually via live webcast and on March 1, 2022, the Transaction closed.

At closing the Company received approximately $23.9$22.8 million in proceeds net of $250,000indemnification and purchase price adjustment holdbacks of indemnity$150,000 and $100,000, respectively, and direct expenses of approximately $1.1 million including fees to our advisors. In July 2022, the Company received $225,000 in final purchase price adjustment primarily related to the working capital adjustment and, on March 1, 2023, the Company received the indemnification holdback amounts placed in escrow accounts,amount of which$150,000. In total, the Company received net proceeds of approximately $23.1 million related to the Microlab Transaction. In 2022, the Company used $4.2 million was usedof the Microlab Transaction proceeds to repay in full our outstanding term loan with Muzinich BDC and approximately $700,000$600,000 was used to repay in full our outstanding revolver balance related to the Bank of America credit agreement, $486,000 was used to pay our advisors and $455,000 will be used to pay certain transaction bonuses resulting in an additional $18.0 million in cash to the balance sheet in March. We believe the Transaction allows us to prepare for the next stage of transformation with a stronger concentration of revenues in specialized 5G software and services for 5G private networks and test and measurement applications for the satellite communications, semiconductor and aerospace and defense industries. Furthermore, with the repayment ofagreement. The Company terminated both the Muzinich term loan and the Bank of America credit agreement, we have strengthenedfacility as of the Microlab Transaction date. Additionally, concurrent with the closing, the Company entered into a sublease with RF Industries, Ltd for approximately one-half of the square footage of our corporate headquarters in Parsippany, NJ.

On December 4, 2022, the Company, and its wholly owned subsidiary, Wireless Telecommunications Group, Ltd, a company organized under the laws of England and Wales (“Holdings”), which owns 100% of the outstanding securities of CommAgility, entered into a Securities Purchase Agreement (the “CommAgility Purchase Agreement”) with E-Space Acquisitions LLC, a Delaware limited liability company (“Buyer” or “E-Space”), and eSpace Inc., a Delaware corporation, as guarantor. The CommAgility Purchase Agreement provided for the purchase by the Buyer of 100% of the issued and outstanding equity interests of Holdings (the “Securities”) from the Company. The board of directors or other governing body of each of the Company and the Buyer unanimously approved the CommAgility Purchase Agreement and the transactions contemplated thereby (collectively, the “CommAgility Transaction”). Under the terms of the CommAgility Purchase Agreement, the purchase price for the Securities was estimated to be approximately $14.5 million, inclusive of $13.8 million in cash consideration and a $750,000 note payable, under which the note was subject to agreed-upon reductions of $650,000.

The CommAgility Transaction closed on December 30, 2022 and the Company received net proceeds of $12.2 million which is comprised of the cash consideration of $13.8 million less direct expenses of approximately $1.6 million. The note payable of $750,000 has been offset by agreed-upon reductions of $650,000 for a net balance sheetdue of approximately $100,000 which is due one year from the date of the CommAgility Transaction closing or upon a change in control as defined in the CommAgility Purchase Agreement. The note receivable balance of $100,000 has been further offset by the 2023 UK transaction taxes of approximately $69,000 and increased our liquidity allowing us flexibilitythe expected net proceeds of the note is approximately $31,000.

The CommAgility Transaction and Microlab Transaction resulted in net proceeds of approximately $35.3 million in 2022. As of December 31, 2022, subsequent to investboth the CommAgility Transaction and Microlab Transaction the Company had a cash balance of $20.7 million with no debt or earnout liabilities.

We also compete against smaller offshore vendors with significantly lower costs and expenses than us, such as Sym Technology, Inc., Innowave RF and Wireless Supply.Corporation.

The Company believes its competitive strengths include:

Backlog

The Company’s consolidated backlog of firm orders to be shipped in the next twelve months was approximately $11.7$6.6 million at December 31, 2021,2022, compared to approximately $8.3$5.3 million at December 31, 2020.2021. The increase in backlog is due to higher order flow from our T&M and RFC product groupsin the second half of fiscal 2022 as compared to the prior year. Excluding Microlab, the Company’s backlog at December 31, 2021 was $9.2 million which was approximately $2.1 million or 30% higher than December 31, 2020. It is anticipatedManagement anticipates that the majority of the backlog orders at December 31, 20212022 will be filled during the current year. The stated backlog is not necessarily indicative of Company revenues for any future period nor is a backlog any assurance that the Company will realize a profit from the orders.

Inventory, Supplies and Manufacturing

The Company purchases electronic components, devicesdiodes, aluminum housings and subassembliesprinted wiring assemblies from a wide variety of sources.domestic suppliers. The Company’s procurement policy requires maintaining adequate levels of raw materials inventory to minimize the Company’s production lead times with third-party suppliers and to improve the Company’s capacity to expedite fulfillment of customer orders. During 2022 and 2021, the Company experienced component shortages and longer lead times from suppliers. Although there was no material impact to our consolidated financial statements in 2022 or 2021 as a result of supply chain disruptions, continued component shortages or extended lead times in the future may have an adverse impact on the Company’s operations. ForTwo suppliers accounting for approximately 33% and 37% of consolidated inventory purchases for the year ended December 31, 2022 and 2021, two suppliers each accounted for 12% of total consolidated inventory purchases. For the year ended December 31, 2020, two suppliers each accounted for 14% of total consolidated inventory purchasesrespectively.

The Company is not party to any long-term contracts regarding the deliveries of its supplies and components. ItWe generally purchasespurchase such items pursuant to written purchase orders of both the individual and blanket variety. Blanket purchase orders usually cover the purchase of a larger amount of items at fixed prices for delivery and payment on specific dates.

For Boonton and Noisecom products, the Company develops, designs, manufactures, assembles, calibrates and tests the products at our facility in Parsippany, New Jersey. Testing of Boonton and Noisecom products is generally accomplished at the end of the manufacturing process and is performed in-house, as are all quality control processes.

Approximately 51% of Microlab’s revenues are traced to products that are sourced from offshore vendors. The majority of Microlab products that come from offshore suppliers are subject to tariffs. The remainder of Microlab products are designed and manufactured by the Company in Parsippany, New Jersey. All Microlab products are tested by the Company in Parsippany, New Jersey.

CommAgility hardware products are built by contract manufacturers to CommAgility designs and tested either by the contract manufacturer or by CommAgility. Software products are licensed to customers through a system that allows the customer to download the software once access has been granted.

Holzworth products are designed, developed, assembled and tested in our facility in Boulder, Colorado.

Warranty and Service

The Company typically provides one to three year warranties on all of its products covering both parts and labor. The Company, at its option, repairs or replaces products that are defective during the warranty period if the proper preventive maintenance procedures have been followed by its customers.

In cases of defective products the customer typically returns them to the Company’s facility. The Company’s service personnel typically repair the defective items and ship them back to the customer. Generally, all servicing is done at the Company’s facility, and the Company charges its customers a fee for those service items that are not covered by warranty. If the defective product cannot be repaired, the Company typically replaces the product free of charge but unrepairable products are an infrequent occurrence.

Product Liability Coverage

The testing of electronic communications equipment and the accurate transmission of information entail a risk of product liability to the Company. Product liability claims could be asserted against the Company by end-users of any of the Company’s products. The Company maintains product liability insurance coverage. No claims have been asserted for product liability due to a defective or malfunctioning device in the past five years.

Intellectual Property

We believe that our intellectual property, including its methodologies, is critical to our success and competitive position. We rely primarily on a combination of U.S. and foreign patents, copyrights, trademarks and trade secrets, as well as confidentiality agreements to establish and protect our proprietary rights. All employees are subject to the Company’s policies to ensure that all of the Company’s intellectual property and business information are maintained in confidence. Key employees have signed non-disclosure and non-competition agreements.

Regulation

Environmental

The Company’s operations are subject to various federal, state and local environmental laws, ordinances and regulations that limit discharges into the environment, establish standards for the handling, generation, use, emission, release, discharge, treatment, storage and disposal of, or exposure to, hazardous materials, substances and waste,wastes, and require cleanup of contaminated soil and groundwater.

As a result of the Microlab divestiture, the Company filed a General Information Notice with the New Jersey Department of Environmental Protection (“NJDEP”) for our corporate headquarters in Parsippany, N.J. in accordance with the New Jersey Industrial Site Recovery Act (“ISRA”). Additionally, the Company engaged a Licensed Site Remediation Professional (“LSRP”) to perform a Preliminary Assessment (“PA”) at the siteand Site Investigation (“SI”) in accordance with the provisions of ISRA. The PA is identifying several areas requiring further environmental investigation. In accordance with ISRA, in February 2022, the Company posted a $100,000 letter of credit with the NJDEP. The PA identified several areas requiring further environmental investigation which were addressed as part of the SI report.

In December 2022, the Company will engagereceived the SI report from the LSRP. The SI report identified several areas requiring additional investigation most notably elevated concentrations of hazardous substances in the groundwater that were above state and federal limits. The SI report also stated that the groundwater contamination predates our occupancy at our headquarters. We engaged our LSRP to perform additional testing in the first quarter of 2023 to further investigationrefine the Company’s understanding of the contamination. As a result of the testing performed in the first quarter of 2023, it is suspected that the groundwater contamination originated from an offsite source. Further testing is being conducted to validate the findings.

As the Company believes that hazardous substances in soil and groundwater at our Parsippany headquarters predate our occupancy and/or were caused by unrelated third parties, we believe that others, and not the Company, should be responsible for the cost of remediation. However, we cannot guarantee that we will be successful in absolving the Company of the remediation liability. Based on our reasonable position that we did not cause the contamination we do not think our potential liability would be material.

In fiscal 2022 the Company incurred approximately $140,000 in expenses related to testing atand assessments associated with ISRA which are recorded as general and administrative expenses in the site duringConsolidated Statements of Operations and Comprehensive Income. As of December 31, 2022, in orderthe Company has not accrued a liability related to determine what, if any,the estimated remediation is required. At this time, while it cannot be guaranteed,expenses due to the fact that the Company does not anticipate that material expenditures willbelieve it should be required to meet current or pending environmental requirements under ISRA.ultimately responsible for the remediation.

Workplace Safety

The Company’s operations are also governed by laws and regulations relating to workplace safety and worker health. The Company believes it is in material compliance with these laws and regulations and does not believe that future compliance with such laws and regulations will have a material adverse effect on its results of operations or financial condition.

ITAR and Export Controls

Certain of the Company’s products may be subject to International Traffic in Arms Regulation, or ITAR. ITAR requires export licenses from the U.S. Department of State for products shipped outside the U.S. that have military or strategic applications. Because some of the Company’s products could have military or strategic applications, it must ensure its compliance with ITAR.

In addition, the Company is subject to the Export Administration Regulations, or EAR, which regulates the export of certain “dual use” items and technologies and, in some instances, requires a license from the U.S. Department of Commerce in connection with sales of the Company’s products.

The Company believes it is in material compliance with all such export regulations.

FAR and DFARS

Certain of the Company’s contracts with the U.S. Government are subject to Federal Acquisition Regulations (“FAR”) regarding government procurement. Further, certain of the Company’s contracts are subject to the IT security requirements of Defense Federal Acquisition Regulation Supplement (“DFARS”) for controlled unclassified information.

The Company believes it is in material compliance with applicable requirements of FAR and DFARS.

Cybersecurity Maturity Model Certification

The Cybersecurity Maturity Model Certification (“CMMC”) framework is designed to protect Federal Contract Information (“FCI”) and Controlled Unclassified Information (“CUI”) that is handled, stored and/or processed by Defense Industrial Base contractors and is being implemented to further protect the mission of the U.S. Department of Defense (“DOD”). CMMC applies to all DOD contractors and anyone in the defense contract supply chain. Certain of our contracts with the defense subcontractors or direct with the U.S Government may require compliance with CMMC. The original timeline for implementation of CMMC was based on a five-year phased rollout schedule. The Company is in the process of completing self-assessments to comply with CMMC.

EmployeesHuman Capital

The Company is not subject to collective bargaining agreements in the United States or internationally and considers its relationship with its employees to be good. On February 28, 2022, immediately prior to the Microlab divestiture the Company had 155 full time employees.

Pandemic-RelatedGlobal Economic and Supply-Chain Risks

The COVID-19 pandemicAdverse global economic conditions and the related impact on our supply chain and the markets where we do business could materially adversely affect our financial condition, future plans and results of operations.

The COVID-19 pandemic has had a significant adverse effect onuncertain state of the global economy in(including the current conflict between Russia and Ukraine and related economic and other retaliatory measures taken by the United States, European Union and globallyothers) continues to impact businesses around the world. The conflict between Russia and on most businesses.Ukraine has led to and is expected to continue to lead to disruption, instability and volatility in global markets and industries. Our business has been and may continue to be negatively impacted by such conflict. The Company is not able toU.S. government and other governments in jurisdictions in which we operate have imposed severe sanctions and export controls against Russia and Russian interests and threatened additional sanctions and controls. Deteriorating economic conditions or financial uncertainty in any of the markets in which we sell our products could reduce business confidence and adversely impact spending patterns, and thereby could adversely affect our sales and results of operations. In challenging and uncertain economic environments such as the current one, we cannot predict the ultimatewhether or when such circumstances may improve or worsen, or what impact, that COVID -19 willif any, such circumstances could have on its business; however, if the pandemic and government action in response thereto impose limitations on operations of our customers or suppliers or result in a prolonged supply-chain constraints, labor shortages, economic recession or depression, the Company’s development and implementation of its strategic plan, as well as our ability to generate material revenue therefrom, could be hindered, which would have a material negative impact on the Company’sbusiness, financial condition and results of operations. While vaccinations beginningoperations, or on the price of our common stock.

Our operations are dependent on the ability of suppliers to deliver quality components, devices and printed wiring assemblies in 2021 allowed fortime to meet critical manufacturing and distribution schedules. If we experience any constrained supply of component parts due to global economic recovery, recentuncertainties, such constraints, if persistent, could adversely affect operating results until alternate sourcing can be developed. There could be an increased risk of supplier constraints in periods where we are increasing production volume to meet customer demands. Volatility in the prices of these component parts, an inability to secure enough components at reasonable prices to build new products in a timely manner in the quantities and evolving variantsconfigurations demanded or, conversely, a temporary oversupply of the virus, as well as reduced efficacy of vaccines over time and the possibility that a large number of people decline to get vaccinated or receive booster shots, creates inherent uncertainty as to the potentialthese parts, could adversely affect our future impact of the pandemic on our business, our industry and the economy in general.operating results.

Rising inflation may negatively impact our profit margins

Recent inflationary pressures have increased the cost of energy and raw materials and may adversely affect our results of operations. If inflation continues to rise and further impact the cost of energy and raw materials, we may not be able to offset cost increases to our products through price adjustments without negatively impacting consumer demand, which could adversely affect our sales and results of operations.

Strategic Risks

The Microlab business has historically accounted for a substantial portion ofOur operating results and financial condition could be harmed if the markets into which we sell our revenue. Subsequent to the divestiture of Microlab on March 1, 2022, we are entirely dependent on our remaining business units.products decline or do not grow as anticipated.

The Microlab business accountedVisibility into our markets is limited. Our quarterly sales and operating results are highly dependent on the volume and timing of technology-related spending and orders received during the fiscal quarter, which are difficult to forecast and may be cancelled by our customers. In addition, our revenues and earnings forecasts for 36.1% and 42.3%future fiscal quarters are often based on the expected seasonality or cyclicality of our consolidated revenuesmarkets. However, due to the uncertainties and volatile economic environment created by increased geopolitical tensions, including the war between Russia and Ukraine, the impact of inflation, the potential for future recession, and continued supply chain challenges, the years ended December 31, 2021markets we serve may experience increased volatility and 2020, respectively. Effective March 1, 2022, we sold Microlab and will no longer benefit from its performance and are entirely dependent uponmay not experience the Boonton, Holzworth and Noisecom brands within our test and measurement product group, and the CommAgility brand within our radio, baseband, and software product group. Although we expect the revenue generated from our remaining businesses to grow in the future, our business will be substantially different following the sale of Microlab, and there can be no assuranceseasonality or cyclicality that we will achieve sustained growth, achieve or sustain profitability, or generate positive cash flows from the test and measurement and radio, baseband and software product groups, or in new products or business opportunities we may pursue.

We depend on the deployment of 4G LTE and 5G NR private networks and specialized applications in wireless baseband and related services to grow our business, and our business may be harmed if our customers are unsuccessful in the deployment of such technology and applications or if they deploy technologies that are not supported by our solutions.

We depend on the deployment of 4G LTE and 5G NR wireless private networks and specialized applications in wireless baseband which are supported by our CommAgility software licenses and services. Deployment of private networks in support of industrial internet of things (“IOT”) networks, non-terrestrial communications, transportation networks and air to ground networks requires significant capital expenditure by customers. If new deployments of these specialized technologies are delayed because of a lack of capital or other issues, or if we are unsuccessful in winning new projects for deployment of 4G LTE and 5G NR private networks, our financial results could be adversely affected.

Our future success depends on our ability to anticipate and to adapt to technological changes and to develop, implement and market product innovations.

Many of our markets are characterized by advances in information processing and communications capabilities that require increased transmission speeds and greater bandwidth. These advances require ongoing improvements in the capabilities of our products. However, we may not be successfulexpect. Any decline in our ongoing improvement efforts if, among other things, our products:

There are various competitive wireless technologies that could be a substitute for the products we sell. The failure to successfully introduce new or enhanced products on a timely and cost-competitive basis or the inability to continue to market existing products on a cost-competitive basis could have a material adverse effect on our results of operations and financial condition. In addition, revenues from new products may replace revenues from some of our existing products, mitigating the benefits of new product introductions and possibly resulting in excess levels of inventory.

Furthermore, we must make long-term investments and commit significant resources before knowing whether our investments will eventuallycustomers’ markets would likely result in products that the market will accept. We must accurately forecast volumes, mix of products and configurations that meet customer requirements, and we may not succeed. If we do not succeed, we may be left with inventories of obsolete products or we may not have enough of some products available to meet customera reduction in demand which could lead to reduced revenues and higher expenses.

Our business is dependent on capital spending on data and communication networks by customers or end users offor our products and reductions in such capital spending could adversely affectservices. If our business.

Our performance is dependent on customers’ or end users’ capital spending for constructing, rebuilding, maintaining or upgrading data and communication networks, which can be volatile or hard to forecast. Capital spending in the communications industry is cyclical and can be curtailed or deferred on short notice. A variety of factors affect the amount of capital spending, and therefore, our revenues and profits, including:

Our customers or the end users of our products may not purchase new equipment at levels we have seen in the past or expect in the future. Accordingly,markets decline, we may not be able to maintain or increasecollect on outstanding amounts due to us. Such declines could harm our revenue in the future, and our business, financial condition,position, results of operations, and cash flows and stock price, and could be materially adversely affected.limit our profitability. In such an environment, pricing pressures could intensify. Since a significant portion of our operating expenses is relatively fixed in nature due to sales, R&D and manufacturing costs, if we were unable to respond quickly enough, these pricing pressures could further reduce our operating margins.

The cyclicality of our end-user markets could harm our financial results.

Many of the end markets we serve including but not limited to the commercial wireless market, have historically been cyclical and have experienced periodic downturns. The factors leading to and the severity and length of a downturn are very difficult to predict and there can be no assurance that we will appropriately anticipate changes in the underlying end markets we serve or that any increased levels of business activity will continue as a trend into the future. If we fail to anticipate changes in the end markets we serve, our business, results of operations and financial condition could be materially adversely affected.

Our industry is highly competitive and if we are not able to successfully compete, we could lose market share and our revenues could decline.

We operate in industries characterized by aggressive competition, rapid technological change and evolving technology standards and short product life cycles.standards. Current and prospective customers for our products evaluate our capabilities against the merits of our direct competitors. We compete primarily on the basis of technology and performance.

We also compete on price. Our competitors may introduce products that are competitively priced, have increased performance or functionality or incorporate technological advances that we have not yet developed or implemented.

To remain competitive, we must continue to develop, market and sell new and enhanced products at competitive prices, which will require significant research and development expenditures. If we do not develop new and enhanced products or if we are not able to invest adequately in our research and development activities, our business, financial condition and results of operations could be negatively impacted.

Many of our competitors are substantially larger than we are, and have greater financial, technical, marketing and other resources than we have. Many of these large enterprises are in a better position to withstand any significant reduction in capital spending by customers in our markets. They often have broader product lines and market focus and may not be as susceptible to downturns in a single market. These competitors may also be able to bundle their products together to meet the needs of a particular customer and may be capable of delivering more complete solutions than we are able to provide. To the extent large enterprises that currently do not compete directly with us choose to enter our markets by acquisition or otherwise, competition would likely intensify.

We are exposed to risks associated with acquisitions and investments which could cause us to incur unanticipated costs and liabilities and harm our business and results of operations.

On February 7, 2020, we acquired Holzworth Instrumentation, Inc., a company based in Denver,Boulder, Colorado. Additionally, in the future we may make acquisitions of, or significant investments in, businesses with complementary products, services and/or technologies. The Holzworth acquisition and future acquisitions and investments involve numerous risks, including, but not limited to:

If we are unable to address these difficulties and challenges or other problems encountered in connection with any future acquisition or investment, we might not realize the anticipated benefits of that acquisition or investment and we could incur unanticipated costs, liabilities or otherwise suffer harm to our business generally. The difficulties and challenges of successful integration of any acquired company are increased when the integration involves companies with operations or material vendors outside the United States.

To the extent that we pay the consideration for any future acquisitions or investments in cash or any potential cash earn outs, it has reduced and may in the future reduce the amount of cash available to us for other purposes. Such payments also may increase our cash flow and liquidity risk. Future acquisitions or investments could also result in dilutive issuances of our equity securities or the incurrence of debt, contingent liabilities, amortization expenses or impairment charges against goodwill or intangible assets on our balance sheet, any of which could have a material adverse effect on our business, results of operations and financial condition.

Operational Risks

ShortagesFailure to renegotiate the terms of our current lease for our corporate headquarters or delays of suppliesfind another location suitable for component partsour operations could adversely affectimpact our operating results until alternate sources can be developed.of operations.

Our lease for our corporate headquarters and N.J operations in Parsippany expires on March 31, 2023. We are in negotiations with the landlord for an extension and are also exploring other locations to lease. Should we not come to terms with the landlord on an extension by the lease termination date we could incur charges above fair value for rent for industrial and office property which could have an adverse impact our results of operations.

The loss of key personnel could adversely affect our ability to remain competitive; our development of new and upgraded products could be adversely impacted by our inability to hire or retain personnel with appropriate technical abilities.

We believe that the continued service of our executive officers will be important to our future growth and competitiveness. However, other than the employment agreements we entered into with our named executive officers, Timothy Whelan, Mike Kandell, Alfred Rodriguez and Dan Monopoli, we currently do not have any other employment agreements with our management team. We cannot provide assurance that any key members of our management team will remain employed by us.

Additionally, the design and manufacture of our products require substantial technical capabilities in many disparate disciplines, from engineering, software programming, mechanics and computer science to electronics and mathematics. In the last 12 months we have lost several key engineering resources. We believe thatour pay levels are competitive within the continued employment ofregions in which we operate. However, global labor shortages, inflationary pressure on wages, and increased global attrition have intensified competition for talent in most fields in which we operate, and it may become more difficult to retain key members ofemployees. If we fail to retain key personnel and are unable to hire highly qualified replacements, we may not be able to meet key objectives, such as launching effective product innovations and meeting financial goals, and maintain or expand our technical and sales staffs will be important to us but, as with our management team, we cannot assure you that they will remain employed by us.business.

Furthermore, our ability to research and develop new technologies and products, or upgraded versions of existing products, will depend, in part, on our ability to hire personnel with knowledge and skills that our current personnel do not have. If we are unable to hire or retain such qualified personnel, our revenues could be negatively impacted, and our business could suffer.

Our future research and development projects might not be successful.

The successful development of telecommunicationsnew products can be affected by many factors. Products that appear to be promising at their early phases of research and development may fail to be commercialized for various reasons, including the failure to obtain the necessary regulatory approvals.reasons. There is no assurance that any of our future research and development projects will be successful or completed within the anticipated timeframe or budget or that we will receive the necessary approvals from relevant authorities, customers, or prospective customers, for the production of these newly developed products, or that these newly developed products will achieve commercial success. Even if such products can be successfully commercialized, they may not achieve the level of market acceptance that we expect.

Dependence on contract manufacturing and outsourcing other portions of our supply chain might adversely affect our ability to bring products to market and could damage our reputation.

As part of our efforts to streamline operations and to minimize costs, we outsource aspects of our manufacturing processes and other functions and continue to evaluate additional outsourcing. If our contract manufacturers or other outsourcers fail to perform their obligations in a timely manner or at satisfactory quality levels, our ability to bring products to market and our reputation could suffer. For example, during a market upturn, our contract manufacturers might be unable to meet our demand requirements, which could preclude us from fulfilling our customers’ orders on a timely basis. The ability of these manufacturers to perform is largely outside of our control. Additionally, changing or replacing our contract manufacturers or other outsourcers could cause disruptions or delays.

If our products do not perform as promised, we could experience increased costs, lower margins and harm to our reputation.

The failure of our products to perform as promised could result in increased costs, lower margins and harm to our reputation. We may not be able to anticipate all of the possible performance or reliability problems that could arise with our existing or new products, which could result in significant product liability or warranty claims. In addition, any defects found in our products could result in a loss of revenues or market share, failure to achieve market acceptance, injury to our reputation, indemnification claims, litigation, increased insurance costs and increased service costs, any of which could discourage customers from purchasing our products and materially harm our business.

Our business and operations could suffer in the event of security breaches.

Attempts by others to gain unauthorized access to information technology systems are becoming more sophisticated and are sometimes successful. These attempts, which might be related to industrial or other espionage, include covertly introducing malware to our computers and networks and impersonating authorized users, among others. We seek to detect and investigate all security incidents and to prevent their recurrence, but in some cases, we might be unaware of an incident or its magnitude and effects. The theft, unauthorized use or publication of our intellectual property and/or confidential business information could harm our competitive position, reduce the value of our investment in research and development and other strategic initiatives or otherwise adversely affect our business. To the extent that any security breach results in inappropriate disclosure of our customers’ or licensees’ confidential information, we may incur liability as a result. In addition, we might be required to devote significant additional resources to the security of our information technology systems.

We rely on our information technology systems to manage numerous aspects of our business and a disruption of these systems could adversely affect our business.

Our information technology, or IT, systems are an integral part of our business. We depend on our IT systems for scheduling, sales order entry, purchasing, materials management, accounting, and production functions. Our IT systems also allow us to ship products to our customers on a timely basis, maintain cost-effective operations and provide a high level of customer service. Some of our systems are not fully redundant, and our disaster recovery planning does not account for all eventualities. A serious disruption to our IT systems could significantly limit our ability to manage and operate our business efficiently, which in turn could have a material adverse effect on our business, results of operations and financial condition.

We rely on manufacturers’ representatives to sell our products to key large accounts and the loss of a key manufacturer’s representative could have a material impact on our revenues

Our products are sold through a small in-house direct sales force as well as a network of industry specific manufacturers’ representatives that have established relationships with our largest customers. Our arrangements with our manufacturers’ representatives generally can be canceled by either party with advance written notice. The loss of a manufacturer’s representative could result in a material decline in revenues.

Financial Risks

Rising inflation may negatively impact our profit margins

Although the rate of inflation has been low in recent years, we are currently experiencing a significant rise in inflation. An inflationary environment can increase the cost of products we purchase as well as our labor and transportation costs. However, economic conditions and market factors may make it difficult for us to raise our prices enough to keep up with the rate of inflation which could reduce our profit margins or reduce the number of customers who purchase our products. If the current inflationary environment continues or worsens, we may not be able to adjust the pricing we charge for our products to offset increasing product costs, which would adversely impact our results of operations and cash flows.

We incur significant costs as a result of operating as a public company, and our management devotes substantial time to compliance initiatives.

We have incurred and will continue to incur significant legal, accounting and other expenses as a public company, including costs resulting from public company reporting obligations under the Exchange Act and regulations regarding corporate governance practices. The listing requirements of the NYSE American require that we satisfy certain corporate governance requirements relating to director independence, distributing annual and interim reports, stockholder meetings, stockholder approvals and voting, and soliciting proxies. Our management and other personnel will need to devote a substantial amount of time to ensuring compliance with all of these requirements.

Our results of operations could be affected by changes in tax-related matters.

A number of factors could cause our tax rate to increase, including a change in the jurisdictions in which our profits are earned and taxed; a change in the mix of profits from those jurisdictions; changes in available tax credits; changes in applicable tax rates; changes in accounting principles. We have deferred tax assets on our balance sheet. Changes in applicable tax laws and regulations or in our business performance could affect our ability to realize those deferred tax assets, which could also affect our results of operations.

Our stock price is volatile and the trading volume in our common stock is less than that of other larger companies in the wirelesstest and advanced communications industries.measurement industry.

The market price of our common stock has experienced significant volatility and may continue to be subject to rapid swings in the future. From January 1, 2015 to February 3, 2022,17, 2023, the trading prices of our stock have ranged from $0.71 to $4.07 per share. There are several factors which could affect the price of our common stock unrelated to our financial performance, including announcements of technological innovations for new commercial products by us or our competitors, developments concerning propriety rights, new or revised governmental regulation or general conditions in the market or for our products, and the entrance of additional competitors into our markets.

Although our common stock is listed for trading on the NYSE American, the trading volume in our common stock is less than that of other, larger companies in the wirelesstest and advanced communications industries.measurement industry. Traditionally, the trading volume of our common stock has been limited. For example, for the 90 trading days ending on February 15, 2022,17, 2023, the average daily trading volume was approximately 68,00022,000 shares per day and ranged from between 2,300900 shares per day and approximately 2.3 million109,000 shares per day. Furthermore, we only have 22,666,07421,438,571 shares of common stock outstanding as of the date of this report. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of willing buyers and sellers of our common stock at any given time. Because of our limited trading volume, holders of our common stock may not be able to sell quickly any significant number of shares, and any attempted sales of a large number of our shares will likely have a material adverse impact on the price of our common stock.

If securities or industry analysts do not publish research or reports about our business or if they issue an adverse or misleading opinion regarding our stock, our stock price and trading volume could decline.

The trading market for our common stock might be influenced by the research and reports that industry or securities analysts publish about us or our business. If any analysts issue an adverse or misleading opinion regarding us, our business model, products or stock performance, our stock price could decline.

Legal and Regulatory Risks

We could be subject to significant costs related to environmental contamination from past operations, and environmental contamination caused by ongoing operations could subject us to substantial liabilities in the future.

The Company’s operations are subject to various federal, state, local, and foreign environmental laws, ordinances and regulations that limit discharges into the environment, establish standards for the handling, generation, use, emission, release, discharge, treatment, storage and disposal of, or exposure to, hazardous materials, substances and waste, and require cleanup of contaminated soil and groundwater.

In connection with the Microlab divestiture the Company engaged an LSRP to perform a preliminary environmental assessment and site investigation in accordance with ISRA. The site investigation detected hazardous substances in the groundwater at our headquarter in Parsippany NJ. The Company believes the contamination predates our occupancy and, accordingly, remediation should not be the responsibility of the Company. However, we cannot guarantee that we will be successful in absolving the Company of the remediation liability. Based on our reasonable position that we did not cause the contamination we do not think our potential liability would be material.

The testing and use of electronic communications equipment and the accurate transmission of information entail a risk of product liability claims being asserted by customers and third parties.

Claims may be asserted against us by end-users of any of our products for liability due to a defective or malfunctioning device made by us, and we could be subject to corresponding litigation should one or more of our products fail to perform or meet certain minimum requirements. Such a claim and corresponding litigation could result in substantial costs, diversion of resources and management attention, termination of customer contracts and harm to our reputation.

We are subject to laws and regulations governing government contracts, and failure to address and comply with these laws and regulations could harm our business by leading to a reduction in revenue associated with these customers and subjecting us to civil and criminal penalties.

We have agreements relating to the sale of our products to U.S. government entities and, as a result, we are subject to various statutes and regulations that apply to companies doing business with the U.S. government. The laws governing government contracts differ from the laws governing private contracts. For example, many government contracts contain pricing terms and conditions that are not applicable to private contracts. We are also subject to investigation for compliance with the regulations governing government contracts. A failure to comply with these regulations might result in suspension of these contracts, or civil and criminal penalties.

We could be subject to significant costs related to environmental contamination from past operations, and environmental contamination caused by ongoing operations could subject us to substantial liabilities in the future.

The Company’s operations are subject to various federal, state, local, and foreign environmental laws, ordinances and regulations that limit discharges into the environment, establish standards for the handling, generation, use, emission, release, discharge, treatment, storage and disposal of, or exposure to, hazardous materials, substances and waste, and require cleanup of contaminated soil and groundwater.

Certain of our products and our business are subject to ITAR, Export Administration Regulations, Foreign Corrupt Practices Act and other U.S. and foreign government laws, regulations, policies and practices, and our failure to comply with such regulations could adversely affect our business, results of operations and financial condition.

Our international revenues, for which we also use foreign representatives and consultants, are subject to U.S. laws, regulations and policies, including the ITAR and the U.S. Foreign Corrupt Practices Act, or the FCPA, and other export laws and regulations, as well as foreign government laws, regulations and procurement policies and practices which may differ from the U.S. government regulations in this regard.

Compliance with the directives of the U.S. Department of State may result in substantial legal and other expenses and the diversion of management time. In the event that a determination is made that we or any entity we have acquired has violated the ITAR with respect to any matters, we may be subject to substantial monetary penalties that we are unable to quantify at this time, and/or suspension or revocation of our export privileges and criminal sanctions, which may have a material adverse effect on our business, results of operations and financial condition.

We can give no assurance that under either the ITAR or the EAR we will continue to be successful in obtaining the necessary licenses and authorizations or that certain revenues will not be prevented or delayed due to compliance issues related to the ITAR or the EAR.

We are also subject to, and must comply with, the FCPA and similar world-wide anti-corruption laws, including the U.K. Bribery Act of 2010. These acts generally prohibit both us and our third party intermediaries from making improper payments to foreign officials for the purpose of acquiring or retaining business or otherwise obtaining favorable treatment. We are required as well to maintain adequate record-keeping and internal accounting practices to fully and accurately reflect our transactions. We operate in many parts of the world that have experienced government corruption. In certain circumstances, the FCPA and our programs and policies may conflict with local customs and practices. If we or any of our local intermediaries have failed to comply with the requirements of the FCPA, governmental authorities in the United States could seek to impose severe criminal and civil penalties. The assertion of violations of the FCPA or other anti-corruption laws could disrupt our business and have a material adverse effect on our results of operations and financial condition.

We are subject to various other governmental regulations, compliance with which could cause us to incur significant expenses, and if we fail to maintain satisfactory compliance with certain regulations, we could be forced to recall products and cease their distribution, and we could be subject to civil or criminal penalties.

Our business is subject to various other significant international, federal, state and local regulations, including but not limited to health and safety, packaging, product content and labor regulations. These regulations are complex, change frequently and have tended to become more stringent over time. We may be required to incur significant expenses to comply with these regulations or to remedy violations of these regulations. Any failure by us to comply with applicable government regulations could also result in cessation of our operations or portions of our operations, product recalls or impositions of fines and restrictions on our ability to carry on or expand our operations.

Third parties could claim that we are infringing on their intellectual property rights which could result in substantial costs, diversion of significant managerial resources and significant harm to our reputation.

The industries in which our company operates are characterized by the existence of a large number of patents and frequent litigation based on allegations of patent infringement. From time to time, third parties may assert patent, copyright, trademark and other intellectual property rights to technologies in various jurisdictions that are important to our business. Defending claims, including claims without merit, requires allocation of resources, including personnel and capital, which could adversely impact our results of operations. A successful claim of infringement against us could result in our being required to pay significant damages, enter into costly license agreements, or stop the sale of certain products, which could adversely affect our net revenues, gross margins and expenses and harm our future prospects.

We use specialized technologies and know-how to design, develop and manufacture our products. Our inability to protect our intellectual property could hurt our competitive position, harm our reputation and adversely affect our results of operations.

We believe that our intellectual property, including its methodologies, is critical to our success and competitive position. We rely primarily on a combination of U.S. and foreign patent, copyright, trademark and trade secret laws, as well as confidentiality agreements to establish and protect our proprietary rights. If we are unable to protect our intellectual property against unauthorized use by third parties, our reputation among existing and potential customers could be damaged and our competitive position adversely affected.

Attempts may be made to copy aspects of our products or to obtain and use information that we regard as proprietary. Accordingly, we may not be able to prevent misappropriation of our technology or deter others from developing similar technology. Our strategies to deter misappropriation could be undermined if:

If these risks materialize, we could be required to spend significant amounts to defend our rights and to divert critical managerial resources. In addition, our proprietary methodologies could decline in value or our rights to them could become unenforceable. If any of the foregoing were to occur, our business could be materially adversely affected.

Environmental and other disasters, such as flooding, large earthquakes, hurricanes, volcanic eruptions or nuclear or other disasters, or a combination thereof, may negatively impact our business.

Although we manufacture our products in New Jersey and Colorado, we both source and ship our products globally. Environmental and other disasters could cause disruption to our supply chain or impede our ability to ship product to certain regions of the world. There can be no assurance that environmental and/or other such natural disasters will not have an adverse impact on our business in the future.

New Jersey corporate law may delay or prevent a transaction that stockholders would view as favorable.

We are subject to the New Jersey Shareholders’ Protection Act (the “Act”), which could delay or prevent a change of control of us. In general, the Act prevents a shareholder owning 10% or more of a New Jersey public corporation’s outstanding voting stock from engaging in business combinations with that corporation for five years following the date the shareholder acquired 10% or more of the corporation’s outstanding voting stock, unless board approval is obtained prior to the time that the shareholder reaches the 10% threshold.

Failure to maintain effective internal controls in accordance with Sarbanes-Oxley could have a material adverse effect on our business and common stock price.

As a public company with SEC reporting obligations, we are required to document and test our internal control procedures to satisfy the requirements of Section 404(a) of Sarbanes-Oxley, which require annual assessments by management of the effectiveness of our internal control over financial reporting. As a smaller reporting company, we are exempt from the auditor attestation requirement of Section 404(b) of Sarbanes-Oxley.

During the course of our assessment, we may identify deficiencies that we are unable to remediate in a timely manner. Testing and maintaining our internal control over financial reporting may also divert management’s attention from other matters that are important to the operation of our business. We may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404(a) of Sarbanes-Oxley. If we conclude that our internal control over financial reporting is not effective, we cannot be certain as to the timing of completion of our evaluation, testing and remediation actions or its effect on our operations. Moreover, any material weaknesses or significant deficiencies in our internal control over financial reporting may impede our ability to file timely and accurate reports with the SEC. Any of the above could cause investors to lose confidence in our reported financial information or our common stock listing on the NYSE American exchange to be suspended or terminated, which could have a negative effect on the trading price of our common stock.

The Company is subject to compliance with the policies and procedures of the NYSE American Exchange with respect to continued listing on the stock exchange and our failure to maintain our listing would make trades in our securities difficult for shareholders.

In considering whether a security warrants continued trading and/or listing on the NYSE American Exchange, many factors are taken into account, such as the degree of investor interest in the company, its prospects for growth, the reputation of its management, the degree of commercial acceptance of its products, and whether its securities have suitable characteristics for auction market trading. Thus, any developments which substantially reduce the size of a company, the nature and scope of its operations, the value or amount of its securities available for the market, or the number of holders of its securities, might occasion a review of continued listing by the Exchange. Moreover, events such as the sale, destruction, loss or abandonment of a substantial portion of a company’s business, the inability to continue its business, steps towards liquidation, or repurchase or redemption of its securities, may also give rise to such a review. The loss of our listing on the Exchange could have a material adverse effect on our shareholders’ ability to sell our shares or for others to purchase our shares. This could have an adverse effect on the market price of our stock.

International Risks

The conflict between Russia and Ukraine, and related sanctions could negatively impact us.

The conflict between Russia and Ukraine has led to and is expected to continue to lead to disruption, instability and volatility in global markets and industries. Our business could be negatively impacted by such conflict. The U.S. government and other governments in jurisdictions in which we operate have imposed severe sanctions and export controls against Russia and Russian interests and threatened additional sanctions and controls. The impact of these measures, as well as potential responses to them by Russia, is currently unknown and they could adversely affect our business, supply chain, partners or customers.

Our operating results may suffer because of our exposure to foreign currency exchange rate fluctuations.

Substantially all of our sales contracts with our U.S. and international based customers provide for payment in U.S. dollars. A strengthening of the U.S. dollar relative to other foreign currencies could increase the effective cost of our products to our international customers as their functional currency is typically not the U.S. dollar. This could have a potential adverse effect on our ability to increase or maintain average selling prices of our products to our foreign-based customers.

Our future revenue and expenses may be subject to volatility due to exchange rate fluctuations that could result in foreign exchange gains and losses associated with foreign currency transactions and the translation of assets and liabilities denominated in foreign currencies.

The success of our ability to grow revenues and develop relationships in Europe and Asia may be limited by risks related to conducting business in European and Asian markets.

Part of our strategy is to increase revenues and build our relationships in European and Asian markets. Risks inherent in marketing, selling and developing relationships in European and Asian markets include those associated with:

In addition, European and Asian intellectual property laws are different than and might not protect our proprietary rights to the same extent as do U.S. intellectual property laws, and we will have to ensure that our intellectual property is adequately protected in foreign jurisdictions and in the United States. If we do not adequately protect our intellectual property rights, competitors could use our proprietary technologies in non-protected jurisdictions and put us at a competitive disadvantage.

The uncertainty surrounding the implementation and effect of Brexit may cause increased economic volatility, affecting our operations and business.

In June 2016, a majority of voters in the United Kingdom (“U.K.”) elected to withdraw from the European Union (E.U.) in a national referendum (also referred to as “Brexit”). CommAgility is located in the U.K. Although the U.K. and E.U. entered into a trade and cooperation agreement, the political and economic instability created by Brexit may cause significant volatility in global financial markets in the future.

The volatility in financial markets due to Brexit could potentially disrupt the markets we serve and may cause us to lose customers, suppliers and employees. Additionally, disruptions and uncertainty caused by Brexit may cause our customers to closely monitor their costs and reduce their spending budget on our products and services. Any of these effects of Brexit, among others, could adversely affect our business, financial condition or future results.

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

Overview

The Company is a global designer and manufacturer of advanced RF, microwave and millimeter wave components, modules, systems and instruments. Serving the wireless, telecommunication, satellite, military, aerospace, semiconductor and medical industries, Wireless Telecom Group products enable innovation across a wide range of traditional and emerging wireless technologies. With a unique set of high-performance products including peak power meters, signal analyzers, signal generators, phase noise analyzers, signal processing modules, LTE and 5G physical layer and stack software, power splitters and combiners, GPS repeaters, public safety monitors, noise sources, and programmable noise generators, Wireless Telecom Group supports the development, testing and deployment of wireless technologies around the globe.

In 2021, the Company was comprised of five brands – Microlab, Boonton, Noisecom, CommAgility and Holzworth organized as three product groups. Our product groups were organized as follows: Radio Frequency Components (“RFC”) was comprised of our Microlab brand; Radio, Baseband, Software (“RBS”) was comprised of our CommAgility brand; and Test and Measurement (“T&M”) was comprised of our Boonton, Noisecom and Holzworth brands. The financial condition and results of operations described in this Annual Report on Form 10-K include the 2021 results of Microlab.

On March 1, 2022, we sold Microlab to RF Industries, Ltd. Accordingly,Ltd and on December 30, 2022 we sold CommAgility to E-Space Acquisitions, LLC. Subsequent to the divestitures of Microlab and CommAgility the Company currently is comprised of the T&M business which is made up of our Boonton, Noisecom and RBS products groups.Holzworth brands. The T&M business provides RF and microwave test equipment and low phase noise RF synthesizers to equipment manufacturers, aerospace and defense companies, military and government agencies, satellite communication companies, semiconductor companies and other global technology companies.

The Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations presented in this Annual Report on Form 10-K for the fiscal year ended 2022 exclude the results of Microlab and CommAgility for all periods presented. The results of Microlab and CommAgility have been recorded as discontinued operations in accordance with the applicable accounting guidance. Further, the assets and liabilities of Microlab and CommAgility have been reclassified as assets and liabilities of discontinued operations in the Consolidated Balance Sheet as of December 31, 2021.

Key 20212022 Developments and Financial Results

In 20212022, the Company disclosed that we were pursuing strategic alternatives in order to maximize value for our consolidatedshareholders. During the year we completed two divestitures for total proceeds of approximately $35.3 million and repaid all outstanding debt and earnout obligations. As of December 31, 2022, we have approximately $20.7 million in cash. The remaining T&M business generated 57.4% gross margins in fiscal 2022 and ended the year with a backlog of $6.6 million, which was an increase of $1.1 million from the prior year. T&M revenue increased 18.0%declined 1.4% from the prior year drivendue primarily to general economic and global uncertainties which delayed capital expenditure decisions by our customers for our products. T&M and RBS revenues, as we experiencedsecond half bookings in 2022 increased from the first half of the year signaling a recovery from COVID-19 related declines as well as strong demand forin spend by our T&M and RBS solutions. T&M product demand was driven by new product introductions, improved demand generation activities, and a reboundcustomers resulting in customer spending outside the U.S. due in part to relaxed COVID-19 related restrictions. Also contributing to the overall increase in revenue were increased sales of our LTE and 5G software and services driven by new customer contracts for specialized applications and RBS digital signal processing cards.higher backlog.

Our consolidated gross margins were 50.9% in 2021 comparedThe Company continues to 50.2%explore strategic alternatives for the year ago period reflecting increased salesremaining T&M business. We do not expect to comment further or update the market with any additional information on the process unless and until its Board of our higher margin T&M solutions. Our 2021 GAAP operating loss decreased from $8.1 millionDirectors has approved a specific transaction or otherwise deems disclosure appropriate or necessary. There can be no assurance that the evaluation of strategic alternatives will result in 2020any strategic alternative transaction, or any assurance as to $145,000 in 2021. The 2021 GAAP operating loss included a non-cash indefinite lived intangible asset impairment charge of $258,000 and an increase in our contingent consideration liability related to the Holzworth earnout of $386,000. The intangible asset impairment charge was recorded as part of our required annual impairment testing and was triggered primarily by the lower hardware sales at CommAgility as compared to prior years. We continue to be optimistic about CommAgility’s ability to grow software and services revenues as evidenced by our 2021 results which reflect a 140% growth from 2020 driven by new customers and applications. In addition, our recent 2020 acquisition of Holzworth in our T&M product group, continues to outperform our expectations resulting in an increase in the contingent consideration liability noted above of $386,000 related to that brand’s financial performance in 2021. The 2021 earn-out is the second and final earnout period for Holzworth.

In 2021 we generated $4.6 million of cash flow from operations, an increase of $1.6 million from the prior year period, and we continued to carefully manage our capital expenditures which totaled $524,000 for 2021. In June, we received forgiveness of our Paycheck Protection Program Loan in the amount of $2.0 million which is recognized as a gain on extinguishment of debt in other income in the consolidated statement of operations. In the third quarter we raised $563,000 in cash, net of agent commissions and professional fees, as part of our At-the-Market Common Stock Sales offering and later in the third quarter made a prepayment of our Muzinich term debt in the amount of $3.7 million. Overall, our debt less cash,its outcome or net debt, as of December 31, 2021 is zero, a reduction of $3.4 million of net debt from December 31, 2020.timing.

The financial information presented herein includes: (i) Consolidated Balance Sheets as of December 31, 20212022 and 2020;2021; (ii) Consolidated Statements of Operations and Comprehensive Income/(Loss) for the years ended December 31, 20212022 and 2020;2021; (iii) Consolidated Statement of Changes in Shareholders’ Equity for the years ended December 31, 20212022 and 2020;2021; and (iv) Consolidated Statements of Cash Flows for the years ended December 31, 2021 and 2020.

Critical Accounting Policies

Management’s discussion and analysis of the financial condition and results of operations are based upon the consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America, or U.S. GAAP. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amount of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amount of revenues and expenses for each period. The following represents a summary of the Company’s critical accounting policies, defined as those policies that the Company believes are: (a) the most important to the portrayal of our financial condition and results of operations, and (b) that require management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effects of matters that are inherently uncertain. Estimates and assumptions are made by management to assess the overall likelihood that an accounting estimate or assumption may require adjustment. It is reasonably possible that these estimates may ultimately differ materially from actual results. See Note 1 in the Notes to the Consolidated Financial Statements included elsewhere in this Form 10-K for a description of all of our significant accounting policies.

Discontinued Operations

In accordance with Accounting Standards Codification (“ASC”) 205-20 Discontinued Operations, the results of Microlab and CommAgility are presented as discontinued operations in the Consolidated Statements of Operations and Comprehensive Income/(Loss) and, as such, have been excluded from continuing operations. Further, the Company reclassified the assets and liabilities of Microlab and CommAgility as assets and liabilities of discontinued operations in the Consolidated Balance Sheet as of December 31, 2021. The Consolidated Statements of Cash Flows are presented on a consolidated basis for both continuing operations and discontinued operations.

The Company evaluated the Microlab and CommAgility divestitures in accordance with ASC 205-20 and determined that both transactions represented a strategic shift, as defined, in the operations of the Company. Microlab and CommAgility were major discrete lines of business focused on RF passive conditioning and LTE software development, respectively. The remaining T&M business is focused on RF test equipment and phase noise analysis.

In accordance with ASC 205-20 no expenses that are expected to continue in the ongoing entity after divestiture are reported within continuing operations.

Revenue Recognition

Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers (Topic 606), (“Topic 606”) requires the Company to identify the performance obligations in our revenue arrangements – that is, those promised goods and services (or bundles of promised goods or services) that are distinct – and allocate the transaction price of the revenue arrangement to those performance obligations on the basis of estimated standalone selling prices (“SSP’s”).

Sales of hardware which include sales of radio frequency solutions, digital signal processing hardware, power meters, analyzers, noise/signal generators, phase noise analyzers and other componentsour T&M products generally consist of one performance obligation which is satisfied upon shipment to the customer. When contract terms require transfer of control upon delivery at a customer’s location, revenue is recognized on the date of delivery. Sales of hardware to distributors that include a limited right of return are recorded net of expected returns.

Sale of software licenses in the CommAgility brand may involve multiple performance obligations including multiple software releases and consultancy services. In these cases transaction price is allocated to each distinct performance obligation on the basis of SSP and revenue is recognized when the distinct performance obligation is satisfied. The company determines performance obligations and SSP’s in arrangements with multiple performance obligations in accordance with Topic 606 which requires significant judgement.

Services arrangements involving repairs and calibrations of the Company’s products are generally considered a single performance obligation and revenue is recognized as the services are rendered.

Certain software arrangements in the CommAgility brand may involve the transfer of software along with significant customization services. In these cases the customization services and software licenses are combined as one distinct performance obligation and revenue is recognized over time as the project is completed. The duration of these performance obligations are typically one year or less.

Leases

We lease office space and certain equipment under non-cancelable lease agreements. We apply ASU No. 2016-02, Leases (Topic 842) to our lease arrangements. In accordance with Topic 842, we assess all arrangements that convey the right to control the use of property, plant and equipment, at inception, to determine if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, we determine the lease classification, recognition, and measurement at the lease commencement date. For arrangements that contain a lease we: (i) identify lease and non-lease components; (ii) determine the consideration in the contract; (iii) determine whether the lease is an operating or financing lease; and (iv) recognize lease Right of Use (“ROU”) assets and corresponding lease liabilities. Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and lease incentives; and (iii) any impairments of the ROU asset. The interest rate implicit in our lease contracts is typically not readily determinable and as such, we use our incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

Business Combinations

The Company uses the acquisition method of accounting for business combinations which requires the tangible and intangible assets acquired and liabilities assumed to be recorded at their respective fair market value as of the acquisition date. Goodwill represents the excess of the consideration transferred over the fair value of the net assets acquired. The fair values of the assets acquired and liabilities assumed are determined based upon the Company’s valuation and involves making significant estimates and assumptions based on facts and circumstances that existed as of the acquisition date. The Company uses a measurement period following the acquisition date to gather information that existed as of the acquisition date that is needed to determine the fair value of the assets acquired and liabilities assumed. The measurement period ends once all information is obtained, but no later than one year from the acquisition date.

Valuation of Goodwill

Goodwill represents the excess of the aggregate purchase price over the fair value of the net assets acquired in a purchase business combination. Goodwill is evaluated for impairment annually, or more frequently if events occur or circumstances change that would indicate that goodwill might be impaired, by first performing a qualitative evaluation of events and circumstances impacting the reporting unit to determine the likelihood of goodwill impairment. Based on that qualitative evaluation, if we determine it is more likely than not that the fair value of a reporting unit exceeds its carrying amount, no further evaluation is necessary. Otherwise, we perform a quantitative impairment test.

The Company has threeone reporting unitsunit with goodwill –which is Holzworth. The Company’s qualitative assessment of Holzworth Microlab and CommAgility. The Company performed a qualitative assessmentgoodwill in the fourth quarter of 2021 of each reporting unit. The qualitative assessment of Holzworth and Microlab did not indicate any impairment of goodwill. As a result of the reduced hardware sales from prior years, the Company performed a quantitative impairment test of the goodwill of the CommAgility reporting unit.

For goodwill impairment testing using the quantitative approach, the Company estimates the fair value of the selected reporting unit using the income approach and the market approach. Fair value under the income approach is derived primarily through the use of a discounted cash flow model based on our best estimate of amounts and timing of future revenues and cash flows and our most recent business and strategic plans. Fair value under the market approach is derived by applying a multiple to our best estimate of future revenue. The Company applies equal weighting to the income approach and the market approach to arrive at an estimated fair value. The estimated fair value is compared to the carrying value of the reporting unit, including goodwill. If the fair value of the reporting unit exceeds the carrying value,2022 indicated no impairment charge is recorded. If the carrying value of the reporting unit exceeds the fair value an impairment charge is recorded to goodwill in the amount by which carrying value exceeds fair value. Both the income approach and market approach require judgmental assumptions about projected revenue growth, future operating margins, discount rates and terminal values over a multi-year period. There are inherent uncertainties related to these assumptions and management’s judgment in applying them to the analysis of goodwill impairment. While the Company believes it has made reasonable estimates and assumptions to calculate the fair value of its reporting units, it is possible a material change could occur.

The result of our quantitative analysis was that the estimated fair value of the CommAgility reporting unit exceeded its carrying value thus no goodwill impairment charge was recorded in the fourth quarter of 2021. The excess of fair value above its carrying value was approximately 25% of the fair value. Recent operating performance, along with assumptions for specific customer opportunities, were considered in the key assumptions used during the fiscal 2021 impairment analysis. Management of the Company has determined the goodwill of CommAgility may have an increased likelihood of impairment if CommAgility is not able to execute against customer opportunities, and the long-term outlook for their cash flows are adversely impacted. Furthermore, changes in the long-term outlook may result in a change to other valuation assumptions. Factors monitored by management which could result in a change to CommAgility estimates include the outcome of customer requests for proposals and subsequent awards, labor market conditions and levels of overall economic activity.

In the fourth quarter of 2020, the Company recorded a goodwill impairment charge of $4.7 million related to the CommAgility reporting unit. The non-cash impairment charge was due to a number of factors that arose as part of our quantitative assessment as of the valuation date in the prior year, including an assessment of our historical results and the significant decline in hardware sales in 2020, the difficulty of predicting future customer demand, the uncertainty of future sales of 4G hardware cards, the uncertainty of the growth of 5G software and services revenues due to the early stages of 5G adoption for new technology and expectations for 5G deployments, the uncertainty of the impact of the COVID 19 pandemic on customer spending, and the uncertainty for enterprise spending and longer-term investment.

Due to the many variables inherent in the estimation of a reporting unit’s fair value and the relative size of our recorded goodwill, differences in assumptions may have a material effect on the results of our impairment analysis. As of December 31, 2021 and 2020, the Company’s consolidated goodwill balance of $11.5 million was comprised of $1.4 million related to the Microlab reporting unit, $6.0 million related to the Holzworth reporting unit and $4.1 million related to the CommAgility reporting unit.

Intangible and Long-lived Assets

Intangible assets include acquired technology, patents, non-competition agreements, customer relationships and tradenames. Intangible assets with finite lives are amortized using the straight-line method over the estimated economic lives of the assets, which range from threeten to twelvefourteen years. Long-lived assets, including intangible assets with finite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Determination of recoverability is based on an estimate of undiscounted future cash flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss for long-lived assets that management expects to hold and use is based on the estimated fair value of the asset. Long-lived assets to be disposed of are reported at the lower of carrying amount or estimated fair value less costs to sell. The estimated useful lives of intangible and long-lived assets are based on many factors including assumptions regarding the effects of obsolescence, demand, competition and other economic factors, expectations regarding the future use of the asset, and our historical experience with similar assets. The assumptions used to determine the estimated useful lives could change due to numerous factors including product demand, market conditions, technological developments, economic conditions and competition. Intangible assets determined to have indefinite useful lives are not amortized but are tested for impairment annually and more frequently if events occur or circumstances change that indicate an asset may be impaired.

In the fourth quarter of 2021, the Company recorded an impairment charge of $258,000 related to the CommAgility tradename. The non-cash impairment charge was due to a number of factors that arose as part of our quantitative assessment, most notably declining hardware sales since 2019. Additionally, the continued emergence of technical standards and the complexity of the specialized applications that our CommAgility software and related services would be integrated with as part of new customer projects were a factor in the tradename impairment analysis.

Income taxes

The Company records deferred taxes in accordance with ASC 740, “AccountingAccounting for Income Taxes.”Taxes. ASC 740 requires recognition of deferred tax assets and liabilities for temporary differences between tax basis of assets and liabilities and the amounts at which they are carried in the financial statements, based upon the enacted rates in effect for the year in which the differences are expected to reverse. The Company establishes a valuation allowance when necessary to reduce deferred tax assets to the amount expected to be realized. The Company periodically assesses the value of its deferred tax assets and determines the necessity for a valuation allowance.

Realization of the Company’s deferred tax assets is dependent upon the Company generating sufficient taxable income in the appropriate tax jurisdictions in future years to obtain benefit from the reversal of net deductible temporary differences and from utilization of net operating losses. The amount of deferred tax assets considered realizable is subject to adjustment in future periods if estimates of future taxable income are changed.

Uncertain tax positions

Under ASC 740, the Company must recognize and disclose uncertain tax positions only if it is more-likely-than-not that the tax position will be sustained on examination by the taxing authority, based on the technical merits of the position. The amounts recognized in the financial statements attributable to such position, if any, are recorded if there is a greater than 50% likelihood of being realized upon the ultimate resolution of the position.

The Company has analyzed its filing positions in all of the jurisdictions where it is required to file income tax returns. As of December 31, 20212022 and 2020,2021, the Company has identified its federal tax return, the state tax returns in New Jersey, California and Colorado and the United Kingdom as “major” tax jurisdictions, as defined in ASC 740, in which it is required to file income tax returns. Based on the evaluations noted above, the Company has concluded that there are no significant uncertain tax positions requiring recognition or disclosure in its consolidated financial statements.

Based on a review of tax positions for all open years and contingencies as set out in the Company’s Notes to the consolidated financial statements, no significant reserves for uncertain income tax positions have been recorded pursuant to ASC 740 during the years ended December 31, 20212022 and 2020,2021, and the Company does not anticipate that it is reasonably possible that any material increase or decrease in its unrecognized tax benefits will occur within the next twelve months.

Stock-based compensation

The Company follows the provisions of ASC 718, “CompensationCompensation - Stock Compensation”Compensation which requires that compensation expense be recognized based on the fair value of equity awards on the date of grant. The fair value of restricted share awards and restricted stock unit awards is determined using the market value of our common stock on the date of the grant. The fair value of stock options at the date of grant is estimated using the Black-Scholes option pricing model. When stock options are granted, the Company takes into consideration guidance under ASC 718 and SEC Staff Accounting Bulletin No. 107 (SAB 107) when determining assumptions. The expected option life is derived from assumed exercise rates based upon historical exercise patterns and represents the period of time that options granted are expected to be outstanding. The expected volatility is based upon historical volatility of our shares using daily price observations over an observation period that approximates the expected life of the options. The risk-free rate is based on the U.S. Treasury yield curve rate in effect at the time of grant for periods similar to the expected option life. The Company accounts for forfeitures for all equity awards when they occur.

Management estimates are necessary in determining compensation expense for stock options with performance-based vesting criteria. Compensation expense for this type of stock-based award is recognized over the period from the date the performance conditions are determined to be probable of occurring through the date the applicable conditions are expected to be met. If the performance conditions are not considered probable of being achieved, no expense is recognized until such time as the performance conditions are considered probable of being met, if ever. Management evaluates whether performance conditions are probable of occurring on a quarterly basis.

Inventories and Inventory Valuation

Inventories are stated at the lower of cost (average cost) or net realizable value. The Company reviews inventory for excess and obsolescence based on best estimates of future demand, product lifecycle status and product development plans.

Allowances for doubtful accounts

The Company maintains allowances for doubtful accounts for estimated losses resulting from the inability of its customers to make required payments. A key consideration in estimating the allowance for doubtful accounts has been, and will continue to be, our customer’s payment history and aging of our accounts receivable balance.

Warranties

The Company generally offers standard warranties against product defects. We estimate future warranty costs to be incurred based on historical warranty claims experience including estimates of material and labor costs over the warranty period.

Comparison of the results of operations for the year ended December 31, 20212022 with the year ended December 31, 20202021

Net Revenues (in thousands)

Consolidated net revenues increased 18.0%revenue decreased from $22.7 million in fiscal year 2021 to $22.4 million in fiscal year 2022 or 1.4% due primarily to highergeneral negative economic and global uncertainties which caused delays in capital expenditure decisions by our customers resulting in lower sales of our T&M and RBS solutions from the prior year period. T&M sales increased due to new product introductions, improved demand generation activities, and a rebound in customer spending outside the U.S. due in part to relaxed COVID-19 related restrictions. RBS revenues increased due to higher sales of our LTE and 5G software and services driven by new customer contracts for specialized applications and higher sales of our digital signal processing cards. RFC revenues were flat with last year as carrier spending remained low in the first two quarters of 2021 due to the ongoing impacts of the COVID-19 pandemic but increased as compared to the prior year in the third and fourth quarters.products.

Gross Profit (in thousands)

Consolidated gross profit increased $4.1 million primarilydecreased 1% from the prior year period due to higher net revenues at our RBS and T&M product groups as compared to the prior year.lower revenues. Consolidated gross profit margin increased marginally fromof 57% was consistent with the prior year. RBS gross profit margin declined marginally due to higher mix of service revenues in 2021 as compared to 2020 which had a lower margin than software revenues. T&M gross profit margin increased 200 basis points from the prior year, which included certain one-time non-cash purchase accounting adjustments of $448,000. RFC gross profit margin declined 140 basis points from the prior year due to mix and continued market pricing pressures.

Operating Expenses (in thousands)

Consolidated research and development expenses decreased $839,000 or 13.1%increased nominally from the prior year period due primarily to lower third partyan increase in headcount expenses of approximately $100,000 and an increase in depreciation expense of approximately $20,000 only partially offset by a decrease in third-party research and development expenses of $543,000 related to 2020 product development initiatives in our Boonton and CommAgility brands. The mix of third-party research and development expenses to internal expenses varies by project. We expect to continue third party investments in research and development dependent upon project deadlines, new product development opportunities and longer term product roadmap dependencies which, in turn, may create increases and decreases to research and development expenses as a percentage of revenue. Additionally, salaries expense declined from the prior year due primarily to our RBS engineers spending more time on customer service projects resulting in their salaries being classified as costs of revenue rather than research and development expense. These decreases were offset by an unfavorable foreign exchange impact of approximately $226,000 due to the strengthening of the Great British Pound (“GBP”) against the U.S. dollar as compared to the prior year.$50,000.

Sales and marketing expenses increased $214,000 or 3.1% due primarily to higher commissions expense of $217,000 and unfavorable foreign exchange impact of $56,000 due to the strengthening of the GBP to the U.S. dollar as compared towere flat with the prior year offset by other miscellaneous declines in sales and marketing expensesperiod. External commissions expense increased approximately $190,000 from the prior year.year due a larger mix of commissionable sales. Higher external commissions expense was offset by a decrease in headcount related expenses due to lower sales headcount of approximately $113,000 and a decrease in third-party marketing spend of approximately $40,000.

General and administrative expenses increased $2.0 million or 19.8%$562,000 from the prior year due primarily to higher salaries and benefits of $695,000 due to headcount increases at our RBS product group and the full year impact of our Chief Revenue Officer, a higher bonus accrual of $434,000, higher legal and merger and acquisition expenses of $514,000 related to the sale of Microlab, higher insurance costs of $122,000, higher consulting and other market research expenses related to our strategic review process of $300,000 and an unfavorable foreign exchange impact of $126,000 related to the strengthening of the GBP as compared to the prior year.

As a result of the Company’s qualitative evaluation of goodwill, the Holzworth and Microlab reporting units did not indicate any impairment of goodwill. As a result of the factors identified in Note 1, the Company performed a quantitative impairment test of the goodwill of one of the Company’s reporting units, CommAgility as of October 1, 2021. Fair value of the reporting unit was estimated using a combination of the income approach and the market approach methods. The Company used a discounted cash flow model for the income approach method and the guideline public company method for the market approach method. The determination of the fair value of the reporting unit required management to make significant estimates and assumptions related to projected revenue growth, future operating margins, discount rates and terminal values. As disclosed by management, changes in these estimates and assumptions could have a significant impact on the fair value of the reporting unit, the amount of any goodwill impairment, or both. As a result of the quantitative impairment assessment discussed above, the Company determined the excess of fair value above its carrying value was approximately 25% of the fair value at the measurement date.it relates.

Valuation Allowance on State Net Operating Loss Carryforwards

As described in Note 14 to the consolidated financial statements, as of December 31, 2021, the Company has $5.6 million of total deferred tax assets, including $3.5 million for State net operating loss carryforwards. The deferred tax assets for State net operating loss carryforwards is partially offset by a valuation allowance of $2.1 million. As disclosed by management, realization of the Company’s deferred tax assets is dependent upon the Company generating sufficient taxable income in the appropriate tax jurisdictions in future years to obtain benefit from the utilization of net operating losses. In determining whether a valuation allowance is warranted, management evaluates factors such as prior earnings history, expected future earnings, carryback and carryforward periods, and tax strategies that could potentially impact the likelihood of realization of a deferred tax asset. After evaluating the sale of Microlab FXR/LLC, as well as other opportunities that may be available that will impact the utilization of the Company’s State net operating loss carryforwards, management expects to be able to realize some, but not all, of the State net operating loss carryforwards.

The principal considerations for our determination that performing procedures relating to the valuation allowance on State net operating loss carryforwards is a critical audit matter include the significant judgments by management when assessing factors related to expected future earnings, which in turn led to a high degree of auditor judgment, subjectivity, and audit effort in performing procedures and evaluating management’s significant assumptions related to expected future earnings.

Addressing the matter involved performing procedures related to, among others, evaluating management’s assessment of the realizability of the deferred tax assets, including (i) testing the underlying data used by the Company in its analysis and (ii) evaluating the reasonableness of expected future earnings during the applicable periods. Evaluating the reasonableness of management’s estimates and assumptions related to expected future earnings involved evaluating whether the estimates and assumptions used by management were reasonable considering (i) the current and past performance of the Company as filed in historical state income tax returns, (ii) expected future events that could impact state apportionment of income in future periods and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit.
