The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.

Throughout this Quarterly Report on Form 10-Q, including under Part 1, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” we disclose certain ~~measures that the Company has taken in response to the~~ macroeconomic impacts of the ongoing coronavirus (“COVID-19”) pandemic and the ensuing supply chain disruption. The full extent to which the COVID-19 pandemic will directly or indirectly impact the Company’s business, results of operations and financial condition will depend on future developments that remain highly uncertain at this time.

The unaudited interim condensed consolidated financial statements of the Company include the condensed consolidated balance sheets as of ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020,~~2021, and the condensed consolidated statements of cash flows, ~~for the nine months ended September 30, 2021 and 2020,~~ the condensed consolidated statements of operations, condensed consolidated statements of comprehensive ~~income (loss),~~loss, and the condensed consolidated statements of stockholders’ equity for the three ~~and nine~~ months ended ~~September 30,~~March 31, 2022 and 2021, ~~and 2020,~~ respectively.

The unaudited interim condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The significant accounting policies followed by the Company are set forth in the ~~2020~~2021 Form 10-K. There were no material changes in the Company’s significant accounting policies during the three ~~and nine~~ months ended ~~September 30, 2021.~~March 31, 2022. In addition, the Company reaffirms the use of estimates in the preparation of the financial statements as set forth in the ~~2020~~2021 Form 10-K. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the ~~2020~~2021 Form 10-K. The results of operations for the period ended ~~September 30, 2021~~March 31, 2022 may not be indicative of the results for the period ending December 31, ~~2021.~~2022.

Cross-border transactions, both with external parties and in our internal operations, result in exposure to foreign exchange rate fluctuations. We are exposed to currency risk ~~with the Chinese Yuan due to our operations in China, and with other~~by having foreign ~~currencies related to the acquisition of Smarteq (see Note 4) and related to~~locations by having suppliers and employees outside the U.S. Fluctuations could have an adverse effect on our results of operations and cash flows. We manage certain operating activities at the local level with revenues,

costs, assets, and liabilities generally being denominated in local currencies. However, our results of operations and assets and liabilities are reported in U.S. dollars and thus will fluctuate with changes in exchange rates between such local currencies and the U.S. dollar. Gains and losses resulting from transactions originally in foreign currencies and then translated

into U.S. dollars are included in the condensed consolidated statements of operations. For the ~~nine~~three months ended ~~September 30, 2021,~~March 31, 2022, approximately 9%13% of revenues and ~~20%~~18% of expenses were transacted in foreign currencies as compared to 3%2% and 1914% ~~for the nine months ended September 30, 2020. Net foreign exchange losses resulting from foreign currency transactions included in other income, net were $(10)~~ ~~and $(158)~~ for the three months ended ~~September 30, 2021 and 2020, respectively.~~March 31, 2021. Net foreign exchange gains (losses) resulting from foreign currency transactions included in other income ~~net was~~were $~~(54)~~(2) and ~~$(139)~~$8 for the ~~nine~~three months ended ~~September 30,~~March 31, 2022 and 2021 ~~and 2020,~~ respectively.

In January 2017, the Financial Accounting Standards Board (“FASB”) issued ~~Accounting Standards Update (“ASU”),~~ Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-14). This new guidance eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. The changes are effective for smaller reporting companies for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and early adoption is permitted. The Company is currently evaluating the impact that this guidance will have on its consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform ~~(“Topic 848”)~~(Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This update provides optional expedients and exceptions for applying ~~U.S. GAAP~~generally accepted accounting principles to certain contract modifications and hedging relationships that reference London Inter-bank Offered Rate (LIBOR) or another reference rate expected to be discontinued. Topic 848 is effective upon issuance and generally can be applied through December 31, 2022. The Company does not expect the adoption of this standard to have an impact on the financial statements or the related disclosures.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This update requires that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 as if the acquirer had originated the contracts. This ASU should be applied prospectively to business combinations occurring on or after the effective date of the update. This update is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period, but should be applied to all acquisitions occurring in the annual period of adoption. The Company is currently evaluating the impact of ~~Topic 848~~this ASU on our consolidated financial statements and related disclosures.

In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 831): Disclosures by Business Entities about Government Assistance. This Update, which aims to increase transparency of government assistance, requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model. Under this ASU, an entity is required to disclose (1) the types of assistance, (2) an entity’s accounting for assistance, and (3) the effect of the assistance on an entity’s financial statements. This Update is effective for all entities within their scope for financial statements issued for annual periods beginning after December 15, 2021. Early adoption is permitted. The Company evaluated the effect of adoption of the update and concluded it does not have an impact on the consolidated financial ~~statements.~~statements or the related disclosures.

The Company follows accounting guidance for fair value measurements and disclosures, which establishes a fair value hierarchy that requires the Company to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or a liability. As a basis for considering such assumptions, a three-tier fair value hierarchy has been established, which prioritizes the inputs used in measuring fair value as follows:

Level 1: inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

Level 2: inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of assets or liabilities.

Level 3: unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Cash equivalents are measured at fair value and investments are recognized at amortized cost in the Company’s financial statements. Accounts receivable is a financial asset with a carrying value that approximates fair value due to the short-term nature of these assets. Accounts payable, accrued employee compensation and certain operating liabilities are financial liabilities with a carrying value that approximates fair value due to the short-term nature of these liabilities.

On April 30, 2021, the Company acquired all the outstanding stock of Smarteq, ~~Wireless Aktiebolag (“Smarteq”),~~ a Swedish company based in Kista, Sweden, that designs antennas for specialized Industrial IoT and vehicular applications, pursuant to a Share Sale and Purchase Agreement (the “SPA”) between PCTEL and Allgon Aktiebolag, a Swedish company and holder of the outstanding stock of Smarteq. Smarteq owns all the outstanding stock of SAS Smarteq France (“Smarteq France”), which engages in sales of Smarteq products.

Pursuant to the SPA, the Company acquired Smarteq for a cash purchase price consisting of SEK 53.0 million plus working capital adjustments of SEK 1.6 million and an adjustment for the net cash at closing of SEK 2.1 million for total cash consideration of SEK 56.8 million ($6.8 million), all of which was provided from PCTEL’s existing cash. The Company believes the acquisition of Smarteq will provide a strong local presence, expertise, and channel partners to accelerate revenue growth in Europe, as well as a complementary portfolio of ~~products for our Industrial IoT and intelligent transportation customers worldwide.~~products. The results for Smarteq are combined with the Company’s antenna and Industrial IoT device product line. The Company applied the provisions of Accounting Standards Codification ~~(ASC)~~(“ASC”) 805, Business Combinations, in accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired, and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the acquisition date fair values of the net assets acquired and the liabilities assumed. ~~While the~~The Company ~~uses~~used its best estimates and assumptions where applicable to accurately value assets acquired and liabilities assumed at the acquisition date, its estimates are inherently uncertain and subject to refinement. The purchase price allocation is preliminary because the evaluations necessary to assess the fair values of the net assets acquired are still in process.As a result, during the measurement period, which may be up to one year from the acquisition date, the Company will record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments will be recorded to the consolidated statements of operations.date. The operating results of the acquired business are included in the Company’s Consolidated Financial Statements from the date of the acquisition.

The following table summarizes the fair value of purchase consideration to acquire Smarteq:

The Company acquired all of the assets and liabilities of Smarteq, including cash of $0.5 million and debt of $0.1 million.

The following is an allocation of the purchase price as of the April 30, 2021 closing date based upon ~~a preliminary~~an estimate of the fair value of the assets acquired and liabilities assumed by the Company in the acquisition:

The following is a summary of identifiable intangible assets acquired and the related expected lives for the finite-lived intangible assets:

The Company prepared the purchase price allocation for the acquired Smarteq assets and in doing so utilized reports of a third-party valuation expert to calculate the fair value of the identifiable intangible assets. Estimates of fair value ~~require~~required management to make significant estimates and ~~assumptions which are preliminary and subject to change upon finalization of the valuation analysis.~~assumptions. The goodwill recognized is attributable primarily to the acquired workforce, expected synergies, and other benefits that the Company believes will result from integrating the Smarteq operations with the operations of the Company. Updates to and/or completion of the valuations of certain assets acquired and liabilities assumed may result in changes to the recorded amounts of assets and liabilities, with corresponding adjustments to goodwill amounts in subsequent periods. The Company expects to complete the purchase price allocation within 12 months of the respective acquisition date. The areas that are not yet finalized relate to intangible assets, goodwill and inventory.

The fair value of the customer relationships was determined using the multi-period excess earnings method (“MPEEM”). MPEEM estimates the value of an intangible asset by quantifying the amount of residual (or excess) cash flows generated by the future customer cash flows, and discounting those cash flows to the present value. Future cash flows for customers were estimated based on forecasted revenue and costs, taking into account the growth rates, customer attrition, and contributory charges. The fair value of the customer backlog was calculated using the present value of the cash flows associated with the acquired backlog.

The fair values of the trade names, developed technology, and exclusive rights were determined using the relief-from-royalty method. The relief-from-royalty method is a specific application of the discounted-cash-flow method, which is a form of the income approach. It is based on the principle that ownership of the intangible asset relieves the owner of the need to pay a royalty to another party in exchange for rights to use the asset. Key assumptions to estimate the hypothetical royalty rate include observable royalty rates, which are royalty rates in negotiated licenses and market-based royalty rates which are royalty rates found in available market data for licenses involving similar assets.

The fair value of covenants not to ~~non-compete~~compete was estimated using the with-or-without method. The with-and-without method estimates the value of an intangible asset by quantifying the loss of economic profits under a hypothetical condition where only the subject intangible does not exist and needs to be re-created. Projected revenues, operating expenses and cash flows are calculated in each "with" and "without" scenario and the difference in the cash flow is discounted to present value.

Inventory was valued at net realizable value. Raw materials were valued at book value and finished goods were valued assuming hypothetical revenues from finished goods adjusted for disposal costs, profit attributable to the seller and holding costs. An inventory step-up to fair value of $0.5 million was included in the purchase price allocation above. The inventory step-up was calculated based on the net realizable value, on a part-by-part basis, of the inventory on the opening balance sheet. The amortization ~~expense~~of the inventory step-up was recorded based on the consumption of those ~~parts.~~parts and was fully recognized ~~Approximately $0.1 million of the inventory fair value step-up was recognized~~ during the ~~three months ended September 30, 2021 and $0.4 million was recognized during~~period from the ~~nine months ended September 30,~~acquisition date through December 31, 2021.

The Company assumed gross accounts receivable of $1.4 million. Based on Smarteq’s bad debt experience and a review of the receivables, the Company ~~does~~did not ~~anticipate an issue with collectability.~~record material reserves for collection issues.

The Company assumed liabilities in the Smarteq acquisition ~~which~~that primarily consist of accounts payable, accrued employee compensation and certain operating liabilities. The fair value of the liabilities assumed ~~are~~was valued at their cash settlement value.

As part of the acquisition of Smarteq on April 30, 2021, the Company assumed an office lease. The office in Kista, Sweden has 4,080 square feet used for engineering, sales, and administration and the lease term is through July 31, 2023. On the acquisition date, the Company recorded $0.2 million for each of the right-of-use assets and the lease liabilities.

The Company assumed Smarteq France’s five-year loan of approximately $0.1 million with an interest rate of 0.57%. The loan was part of a program from the French Ministry of Economy and Finance to support for French businesses during the COVID-19 pandemic. The loan is denominated in Euros. Payment of the interest and principal on the loan are deferred until June 2022 and the loan term ends in May 2026.

The Company recorded net deferred tax assets of $2.4 million, primarily relating to deferred tax assets for net operating losses. The Company also booked a deferred tax asset for inventory reserves and deferred tax liabilities related to intangible asset amortization that is not deductible for income taxes. ~~The Company booked a full valuation allowance against the net deferred tax assets.~~ While the Company ~~expects~~expected book and tax profits in 2021 and future periods, Smarteq ~~has~~had recorded a three-year cumulative tax loss. Based on this objective evidence and based on uncertainty associated with the COVID-19 pandemic the Company recorded a full valuation allowance on the opening balance sheet.

Goodwill recorded in connection with the acquisition was $3.2 million. The Company does not expect to deduct any of the acquired goodwill for tax purposes. The Company recorded $0.3 million of transaction costs ~~for~~during the ~~three months ended June 30,~~second quarter of 2021 in general and administrative expenses in the ~~statement~~consolidated statements of operations. The transaction costs will not be deductible for income tax purposes.

The unaudited pro forma financial information has been adjusted to reflect the amortization expense for acquired intangibles, removal of historical intangible asset amortization and recognition of expense associated with the step-up of inventory.

The pro forma data is presented for illustrative purposes only, and the historical results of Smarteq are based on its books and records prior to the acquisition and isare not necessarily indicative of the consolidated results of operations of the combined business had the acquisition actually occurred as of January 1, ~~2020.~~2021. In addition, future results may vary significantly from the pro forma results reflected herein and should not be relied upon as an indication of the results of future operations of the combined business. The unaudited pro forma financial information does not reflect any operating efficiencies and cost savings that may be realized from the integration of the acquired entity. For the three months ended September 30, 2021, $2.3 million of revenue and net income of $0.1 million was included in the Company's condensed consolidated statements of operations related to Smarteq. For the nine months ended September 30, 2021, $3.9 million of revenue and a net loss of $0.1 million was included in the Company's condensed consolidated statements of operations related to Smarteq.

The Company’s cash, cash equivalents, and investments consisted of the following:

	September 30,		December 31,		March 31,		December 31,
	2021		2020		2022		2021

Long-term investments		0		4,640
Total	$	32,452	$	40,983	$	27,676	$	30,754

At ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020,~~2021, cash and cash equivalents included bank balances and investments with original maturities of less than 90 days. At ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020,~~2021, the Company’s cash equivalents were invested in highly liquid AAA rated money market funds that are required to comply with Rule 2a-7 of the Investment Company Act of 1940. Such funds utilize the amortized cost method of accounting, seek to maintain a constant $1.00 per share price, and are redeemable upon demand. The Company restricts its investments in AAA money market funds to those invested 100% in either short-term U.S. government agency securities or bank repurchase agreements collateralized by these same securities. The fair values of these money market funds are established through quoted prices in active markets for identical assets (Level 1 inputs). The Company’s cash in U.S. banks is insured by the Federal Deposit Insurance Corporation up to the insurable limit of $250.

The ~~Company had~~ cash in foreign ~~bank~~ accounts of $3.6 million at September 30, 2021 and $2.9 million at December 31, 2020. The Company had $2.6 million and $2.9 million of cash and cash equivalents in bank accounts in China at September 30, 2021 and December 31, 2020, respectively. In addition, the Company had $0.9 million of cash in bank accounts in Sweden and $0.1 million of cash in bank accounts in France at September 30, 2021. The Company’s cash in its foreign bank accounts is not insured. At September 30, 2021, $1.1 million of the cash and cash equivalents in China was ~~invested in a 90-day deposit account classified~~ as ~~cash equivalents and $1.5 million was in cash accounts.~~ follows:

As of ~~September 30, 2021,~~March 31, 2022, the Company has no intention of repatriating the cash in its foreign bank accounts. If the Company decides to repatriate the cash in the foreign bank accounts, it may have trouble doing so in a timely manner. The Company may also be exposed to foreign currency fluctuations and taxes if it repatriates these funds.

At ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020,~~2021, the Company’s investments consisted of corporate bonds with ratings at the purchase date of A or higher and certificates of deposit. All the investments at ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020~~2021 were classified as held-to-maturity. The bonds and certificates of deposit classified as short-term investments have original maturities greater than 90 days and mature within one year and the bonds and certificates of deposit classified as long-term investments have maturities greater than one year but less than two years. The Company’s bond investments are recorded at the purchase price and carried at amortized cost.

Effective January 1, 2020, the Company adopted ASU 2016-13. This ASU replaces the incurred loss impairment model with an expected loss impairment model for financial instruments, including short-term investments. The amendment requires entities to consider forward-looking information to estimate expected credit losses. Under ASU 2016-13, the Company classifies its held-to-maturity investment portfolio by the investment type and further classifies the corporate bonds by the bond ratings. For estimating potential credit losses, the Company considers the historical loss data, the bond ratings, as well as ~~and~~ current and future economic conditions.

Cash equivalents and investments were as follows at ~~September 30~~March 31, 2022 ~~, 2021~~ and December 31, ~~2020:~~2021:

The Company categorizes its financial instruments within a fair value hierarchy according to accounting guidance for fair value. The fair value hierarchy is described under the Fair Value of Financial Instruments in Note 2. For the Level 2 investments, the Company uses quoted prices of similar assets in active markets. The fair values in the table above reflect net ~~unrealizable gains of $4 at September 30, 2021, and net unrealized~~realizable losses of $8$1 at March 31, 2022 and December 31, ~~2020.~~ 2021.��

The change in the carrying amount of goodwill during the ~~nine~~three months ended ~~September 30, 2021~~March 31, 2022 is as follows:

The Company performs an annual impairment test of goodwill as of the end of the first month of the fourth fiscal quarter (October 31), or at an interim date if an event occurs or if circumstances change that would indicate that an impairment loss may have been incurred. In performing the annual impairment test, the Company may consider qualitative factors that would indicate possible impairment. A

quantitative fair value assessment is also performed at the reporting unit level. If the fair value exceeds the carrying value, then goodwill is not impaired, and no further testing is performed. If the carrying value exceeds the fair value, the implied fair value of goodwill is then compared against the carrying value of goodwill to determine the amount of impairment. In addition to the annual impairment test, the Company is required to regularly assess whether a triggering event has occurred which would require interim impairment testing. The Company considered the current and expected future economic and market conditions surrounding the COVID-19 pandemic and its impact on each of the reporting units. Further, the Company assessed the current market capitalization and financial forecasts. There were no triggering events during the ~~nine~~three months ended ~~September 30, 2021~~March 31, 2022 and ~~September 30, 2020.~~March 31, 2021. The Company will continue to monitor goodwill for impairment going forward.

The Company amortized intangible assets with finite lives on a straight-line basis over the estimated useful lives, which ranged from one to five years.

The Company is exposed to credit losses primarily through the sale of products. The Company’s expected loss methodology for accounts receivable is developed using historical collection experience, current and future economic market conditions, and a review of the current status of customers’ trade accounts receivable. Due to the short-term nature of accounts receivable, the estimate of amount of accounts receivable that may not be collected is based on aging of the account receivable balances and the financial condition of customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. The Company’s allowance for credit losses was ~~$0.03 million~~$16 at ~~September 30, 2021~~March 31, 2022 and ~~$0.07 million~~$26 at December 31, ~~2020.~~

The Company records allowances to reduce the value of inventory to the lower of cost or net realizable value, including allowances for excess and obsolete inventory. Reserves for excess inventory are calculated based on an estimate of inventory in excess of normal and planned usage. Obsolete reserves are based on the identification of inventory where the carrying value is above net realizable value. The allowance for inventory losses was ~~$4.0~~$3.4 million at ~~September 30, 2021~~March 31, 2022 and ~~$3.7~~$4.1 million at December 31, ~~2020.~~2021.

The intrinsic value is based on the share price of ~~$6.22~~$4.64 at ~~September 30, 2021.~~March 31, 2022.

For outstanding stock options, the Company calculated the fair value of each option ~~grant~~ on the date of grant using the Black-Scholes option-pricing model. Because the Company’s employee stock options have characteristics significantly different from those of traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, the existing models may not necessarily provide a reliable single measure of the fair value of the employee stock options. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility and expected option life.

The dividend yield rate is calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate is based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options granted. The expected volatility is based on a five-year historical period of the Company’s stock price. The expected life for options granted is based on historical data of employee exercise performance. The Company records expense based on the graded vesting method.

~~Incentive compensation earned by~~The Company granted short-term inventive awards to executives, ~~and~~ key managers, and non-sales employees under the Company’s ~~2021~~2022 Short-Term Incentive Plan (“STIP”) based on upon achievement of specifically identified corporate annual 2022 adjusted EBITDA and revenue goals. The 2022 STIP awards, like the 2021 STIP awards, will be ~~settled~~paid 50% in cash and 50% in ~~shares~~the Company’s stock.

In the first quarter 2022 the Board of Directors exercised its discretion to approve awards equal to those payable for achievement of the ~~Company’s stock as was~~adjusted EBITDA goal at the ~~case with~~threshold level. Individuals received awards in an amount equal to the ~~2020 STIP. Under both~~amount that would have been received had the Company and the threshold Adjusted EBITDA. No awards were received by 2021 STIP ~~and 2020 STIP, payouts could be earned based on annual revenue and adjusted EBITDA targets. NaN shares were earned under the 2020 STIP because the Company did not exceed~~participants with respect to the revenue ~~or EBITDA thresholds.~~goal. Bonuses were paid during the first quarter 2022 50% in the Company’s common stock for a total of $0.3 million and 50% in cash for executives and key managers and 100% in cash for all other participants.

The Company grants performance-based awards to executives and key managers to encourage sustainable growth, consistent earnings, and management retention. Based on the fair value of the shares on the grant date, the Company records stock compensation expense over the performance period based on the estimated achievement of the award.

The Company granted performance awards under its long-term incentive plan to executives and key managers in February ~~2021~~2022 (“~~2021~~2022 LTIP”). The performance period for the ~~2021~~2022 LTIP is from January 1, ~~2021~~2022 through December 31, ~~2023.~~2024. At target, the total fair market value of the award was ~~$1.5~~$1.3 million based on the average share price of ~~$8.15~~$4.84 on the grant date. On the award date, the aggregate number of shares that could be earned at target was ~~187,864~~269,618 and the maximum number of aggregate shares that could be earned was ~~328,762.~~471,832.

Under the ~~2021~~2022 LTIP and similar plans from ~~2019~~2021 and 2020, shares of the Company’s stock can be earned based on achievement of a three-year revenue growth target with a penalty if a certain adjusted EBITDA level is not maintained. If the Company achieves less than the target growth over the performance period, the participant will receive fewer shares than the target award, determined on a straight-line basis. If the Company achieves greater than the target growth, the participant will receive more shares than the target award on an accelerated basis. Participants are required to be in service at the determination date of the award following the end of the performance period in order to receive the award. Shares earned will be fully vested shares. The Company records stock compensation expense over the performance period based on the Company’s estimate of the aggregate number of shares that will be earned under the incentive plan.

The following table summarizes the active performance-based long-term incentive plans at ~~September 30, 2021:~~March 31, 2022:

The ESPP enables eligible employees to purchase common stock at the lower of 85% of the fair market value of the common stock on the first or last day of each offering period. Each offering period is approximately six months.

Based on the 15% discount and the fair value of the option feature of the ESPP, it is considered compensatory. Compensation expense is calculated using the fair value of the employees’ purchase rights under the Black-Scholes model.

The Company calculated the fair value of each employee stock purchase grant on the date of grant using the Black-Scholes option-pricing model using the following assumptions:

	Employee Stock Purchase Plan						Employee Stock Purchase Plan
	2021			2020			2022			2021
Dividend yield		3.1	%		4.1	%		4.7	%		3.1	%
Risk-free interest rate		0.1	%		0.1	%		1.7	%		0.1	%
Expected volatility		48	%		44	%		48	%		48	%
Expected life (in years)		0.5			0.5			0.5			0.5

The dividend yield rate was calculated by dividing the Company’s annual dividend by the closing price on the grant date. The risk-free interest rate was based on the U.S. Treasury yields with a remaining term that approximates the expected life of the options

granted. The volatility was based on a five-year historical period of the Company’s stock price. The expected life was based on the offering period.

~~The~~In May, the Company grants equity awards to members of its Board of Directors as an annual retainer and for committee service. These awards are shares of the Company’s common stock that vest ~~upon issuance or, in some cases,~~ one year after issuance.

The ~~following table summarizes the~~number of unvested director awards ~~activity:~~was as follows at March 31, 2022:

For ease in administering the issuance of stock awards, the Company holds back shares of vested restricted stock awards, stock option exercises and short-term and long-term incentive plan stock awards for the value of the statutory withholding taxes. For everyone receiving a share award, the Company redeems the shares it computes as the value for the withholding tax and remits this amount to the appropriate tax authority. For withholding taxes related to stock awards, the Company paid ~~$0.8~~$0.4 million and ~~$1.1~~$0.7 million ~~during the nine months ended September 30, 2021 and 2020, respectively.~~

The~~ Company has been notified that the Chinese Party Central Committee and the State Council are accelerating the layout optimization and transformation of the industrial park in which the Company’s leased premises is located and, accordingly, leases and lease extensions for all premises in the industrial park have been suspended and rent collection has been postponed. However, rent maybe due for the period of the lease suspension.

~~As a result of the uncertainty regarding~~vacated the Tianjin ~~Lease (as defined~~manufacturing facility in Note 11) renewal, the Company refined its transition plan for the manufacturing activities conducted on the leased premises. As part of the refined transition plan, the Company will complete the manufacturing transition by the end of December 2021, reduce headcount,April 2022 and ~~incur additional restructuring charges. The Company will retain~~relocated a small ~~group~~team of employees ~~in Tianjin, China,~~associated with sourcing, quality, and ~~move into~~local customer support at a new leased facility ~~during~~in Tianjin, China. See Note 11 for additional information on the Tianjin lease.

As a cost saving initiative, the Company separated 14 employees from its Beijing office in November 2021. The terminated positions were primarily related to antenna engineering in addition to sales support. The Company incurred restructuring expenses of $0.8 million consisting of employee severance and related employee benefits and for professional fees associated with employee separations. The Company engaged 4 former Beijing employees through a third-party employment agency to provide sales and engineering support. During the first quarter ~~2022.~~of 2022, the Company paid $0.4 million related to severance benefits accrued at December 31, 2021.

The following table summarizes the restructuring activity during the ~~nine~~three months ended ~~September 30, 2021~~ March 31, 2022 and the status of the reserves at ~~September 30~~March 31, 2022~~, 2021:~~

The Company has operating leases for facilities and finance leases for office equipment. Leases with an initial term of 12 months or less are not recorded in the balance sheet. The Company determines if an arrangement is a lease at inception of a contract.

Right of Use (“ROU”) assets represent the Company's right to use an underlying asset during the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. ROU assets and lease liabilities are recognized at the lease commencement date based on the net present value of fixed lease payments over the lease term. The Company's lease term is deemed to include options to extend or terminate the lease when it is reasonably certain that it will exercise that option. ROU assets also include any advance lease payments made and exclude lease incentives. As most of the Company's operating leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments on a collateralized basis. Finance lease agreements generally include an interest rate that is used to determine the present value of future lease payments. Operating ~~fixed~~ lease expense and finance lease depreciation expense are recognized on a straight-line basis over the lease term.

The Company's lease cost for the three ~~and nine~~ months ended ~~September 30,~~March 31, 2022 and 2021, ~~and 2020,~~ respectively, included the following components:

	Three Months Ended September 30,				Nine Months Ended September 30,				Three Months Ended March 31,

~~On March 5, 2020, PCTEL (Tianjin) Wireless Telecommunications Products, Co. Ltd., a wholly owned subsidiary~~The Company completed the transition of antenna manufacturing from its Tianjin, China facility to contract manufacturers during the first quarter of 2022. In April 2022, the Company ~~(“PCTEL Tianjin”), entered into a letter agreement with Wang Zhuang Village Committee of Tianjin, China (the “Letter Agreement”), specifying~~vacated the ~~terms for extension of the lease of the premises on which PCTEL Tianjin currently conducts its~~ manufacturing activities in Tianjin, China (the “Tianjin Lease”) to October 2022. The Letter Agreement did not, however, effect the lease extension. The Tianjin Lease expired on October 8, 2020 without extension. On October 16, 2020, the Wang Zhuang Village Committee issued a notice informing PCTEL Tianjin that the Chinese Party Central Committeefacility and the State Council are accelerating the layout optimization and transformation of the industrial park in which the leased premises is located, and accordingly leases and lease extensions for all premises in the industrial park have been suspended and rent collection has been postponed. The letter indicates that if the Tianjin Lease extension is subsequently approved, the rent for the period from October 9, 2020 to the date of the Tianjin Lease extension (the “Intervening Period”) will then be due and payable. Based upon past practices and verbal assurances, the Company believes that PCTEL Tianjin will have at least 30 days to vacate the leased premises if required by the Wang Zhuang Village Committee to do so. Under the Company’s transition plan, it expects to finish manufacturing in Tianjin by the end of December 2021 and will vacate the facility in the first half of 2022. The Company will retainmoved a small ~~group~~team of employees ~~in Tianjin, China,~~associated with sourcing, quality, and ~~move into~~local customer support to a new leased facility ~~during~~in Tianjin, China. For the new office, the Company entered into a two-year lease ending December 31, 2023 for 1,694 square feet of office space in Tianjin, China. The Company recognized a present value of the right of use asset of $0.1 million for this new office lease.

As a cost saving initiative, the Company separated all 14 employees from its Beijing office in November 2021 and the Company closed this office in the first quarter of 2022. In April 2022, the Company entered into a two-year office lease ending April 30, 2024 for 350 square feet of office space. NaN former employees in Beijing were engaged through a third-party employment agency and will provide sales and engineering support from the new smaller office.

As part of the acquisition of Smarteq on April 30, 2021, the Company assumed an office lease and antwo automotive ~~lease.~~leases. The office in Kista, Sweden has 4,080 square feet used for engineering, sales, and administration with a lease term ending July 31, 2023. On the acquisition date, the Company recorded $0.2 million for each of the ROU assets and the lease liabilities.

As part of the Smarteq acquisition, the Company assumed a five-year loan of approximately $0.1 million with an interest rate of 0.57%. The loan was part of a program from the French Ministry of Economy and Finance as financial support for French businesses during the COVID-19 pandemic. The loan is denominated in Euros. Payment of the principal and interest on the loan is deferred until June 2022 and the loan term ends in May 2026. The amount due within one year is $2, and the remainder is due in equal monthly payments thereafter.

The Company recorded income tax expense of ~~$17~~$8 and ~~$25~~$6 for the ~~nine~~three months ended ~~September 30,~~March 31, 2022 and 2021, ~~and 2020,~~ respectively. The expense recorded for the ~~nine~~three months ended ~~September 30,~~March 31, 2022 and 2021 ~~and 2020~~ was lower than the statutory rate of 21% because the Company has a full valuation allowance on its deferred tax assets. The Company’s valuation allowance is due to the uncertainty regarding the utilization of the deferred tax assets.

The Company had deferred tax assets net of deferred tax liabilities of $15.2 million and $15.3 million at ~~September 30, 2021~~March 31, 2022 and ~~$12.9 million at~~ December 31, ~~2020. The deferred tax assets consisted of domestic deferred tax assets of $12.2~~2021, respectively. By jurisdiction, $11.9 million was associated with the U.S., $1.2 million was associated with China, ~~deferred tax assets of $0.8~~and $2.1 million ~~and Swedish deferred tax assets of $2.3 million.~~was associated with Sweden. The Company’s gross deferred tax assets consist of federal and state net operating losses (“NOLs”), credits, and timing differences. As part of the acquisition of Smarteq, the Company recorded deferred tax assets of $2.3 million associated with NOLs, inventory reserves and recorded tax liabilities associated with acquired intangible assets. Because of the objective evidence of cumulative three-year losses and uncertainty associated with the COVID-19 pandemic, the Company recorded a full valuation allowance on the deferred tax assets.

On a regular basis, the Company evaluates the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment. The Company considers multiple factors in its evaluation of the need for a valuation allowance. The Company’s federal NOLs generated in 2018 and future periods will not expire, and the Company’s NOLs and credits generated as of December 31, 2017 have a finite life primarily based on the 20-year carry forward of federal net operating losses. The timing differences have a ratable reversal pattern over 12 years. On

The Company had a ~~regular basis, the Company evaluates the recoverability of~~full valuation allowance on its net deferred tax assets in each of its jurisdictions at March 31, 2022 and December 31, 2021. For U.S. tax purposes, the ~~need~~Company recorded a book loss during the first quarter 2022. Further, the Company recorded book income during 2021 but generated a tax loss and its earnings were below its projections.

While the ~~nine months ended September 30, 2021. The~~ Company believes its financial outlook remains positive, ~~but due to~~under the accounting standards, objective verifiable evidence will have greater weight than subjective evidence such as the Company’s projections for future growth.

Until an appropriate level of profitability is attained, the Company ~~maintained~~expects to maintain a full valuation allowance on its net deferred tax assets. Any U.S. or foreign tax benefits or tax expense recorded on its consolidated statements of operations will be offset with a corresponding valuation allowance until such time that the Company changes its determination related to the realization of deferred tax assets. In the event that the Company changes its determination as to the amount of deferred tax assets ~~at September 30, 2021 and December 31, 2020.~~that can be realized, the Company will adjust its valuation allowance with a corresponding impact to the provision for income taxes in the period in which such a determination is made.

The analysis that the Company prepared to determine the valuation allowance required significant judgment and assumptions regarding future market conditions as well as forecasts for profits, taxable income, and taxable income by jurisdiction. Due to the sensitivity of the analysis, changes to the assumptions in subsequent periods could have a material effect on the valuation allowance.

The Company files a consolidated federal income tax return, income tax returns with various states, and foreign income tax returns in various foreign jurisdictions. The Company’s U.S. federal tax returns remain subject to examination for 2017 and subsequent periods.

The Company’s U.S. state tax returns remain subject to examination for 2015 and subsequent periods. The Company’s foreign tax returns remain subject to examination for 2011 and subsequent periods. The Company’s gross unrecognized tax benefit was $0.8 million at ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020.~~2021.

The Company had a liability of$0.8 million related to income tax uncertainties at March 31, 2022 and December 31, 2021. We do not know the timing of the settlement of this liability.

On March 27, 2020, the “Coronavirus Aid, Relief and Economic Security Act” (CARES Act) was signed into law. The CARES Act includes provisions relating to refundable payroll tax credits, deferment of the employer portion of certain payroll taxes, net operating loss carryback periods, alternative minimum tax credit refunds, modifications to the net interest deduction limitations and technical corrections to tax depreciation methods for qualified improvement property. Under the CARES Act, the Company ~~is deferring~~deferred the employer portion of social security taxes and ~~will apply~~applied for a refund of its Alternative Minimum Tax credit. As of ~~September 30, 2021,~~March 31, 2022, the Company had deferred ~~$0.5~~$0.2 million of payroll taxes which will be paid ~~in annual installments~~ on ~~December 31, 2021 and~~ December 31, 2022.

Under Topic 606, a contract with a customer is an agreement ~~which~~that both parties have approved, that creates enforceable rights and obligations, has commercial substance, and specified payment terms, and for which collectability is probable. Once the Company has entered into a contract, it is evaluated to identify performance obligations. For each performance obligation, revenue is recognized as control of promised goods or services transfers to the customer in an amount that reflects the consideration the Company expects to receive in exchange for those goods or services. The amount of revenue recognized takes into account variable consideration, such as returns and volume rebates. A majority of the Company’s revenue is short cycle in nature with shipments within one year from order. The Company's payment terms generally range between 30 to 90 days.

All of the Company’s revenue relates to contracts with customers. The Company’s accounting contracts are from purchase orders or purchase orders combined with purchase agreements. The majority of the Company’s revenue is recognized on a “point-in-time” basis and a nominal amount of revenue is recognized “over time.” For the sale of antennas and Industrial IoT ~~products~~devices and test & measurement products, the Company satisfies its performance obligations generally at the time of shipment or upon delivery based on the contractual terms with its customers. For products shipped on consignment, the Company recognizes revenue upon delivery from the consignment location. For its test & measurement software tools, the Company has a performance obligation to provide software maintenance and support for one year. The Company recognizes revenues for the maintenance and support over this period.

The Company considers shipping and handling performed by the Company as fulfillment activities. Amounts billed for shipping and handling are included in revenues, while costs incurred for shipping and handling are included in cost of revenues. The Company excludes taxes from the transaction price. Cost of contracts include sales commissions. The Company expenses the cost of contracts when incurred because the amortization period is one year or less.

The Company allows its major distributors and certain other customers to return unused product under specified terms and conditions. The Company estimates product returns based on historical sales and return trends and records a corresponding refund liability. The refund liability was $0.2 million ~~and $0.1 million~~ at ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020, respectively,~~2021, and is included within accrued liabilities in the accompanying condensed consolidated balance sheets. The Company records an asset based on historical experience for the amount of product it expects to return to inventory as a result of customer returns, which is recorded in inventories in the accompanying condensed consolidated balance sheets. The product return asset was $0.1 million at ~~September 30, 2021~~March 31, 2022 and December 31, ~~2020.~~2021.

There were 0 contract assets at ~~September 30, 2021~~March 31, 2022 or December 31, ~~2020.~~2021. The Company records contract liabilities for deferred revenue and customer prepayments.

On a regular basis, we evaluate the recoverability of deferred tax assets and the need for a valuation allowance. Such evaluations involve the application of significant judgment. We considered multiple factors in our evaluation of the need for a valuation allowance. The full valuation allowance against our deferred tax assets was ~~$15.3~~$15.2 million at ~~September 30, 2021~~March 31, 2022 and ~~$12.9 million~~ at December 31, ~~2020.~~2021. The deferred tax assets consist of domestic deferred tax assets of ~~$12.2~~$11.9 million and foreign deferred tax assets of ~~$3.1~~$3.2 million. As part of the Smarteq acquisition, we recorded $2.3 million of net deferred tax assets. While the Company expects book and tax profits in 2021 and future periods, Smarteq has recorded a three-year cumulative tax loss as of December 31, 2020. Based on this objective evidence and uncertainty associated with the COVID-19 pandemic, the Company recorded a full valuation allowance on the opening balance sheet for Smarteq.

We recorded pretax book income during ~~2020~~2021 and believe our financial outlook remains positive. However, the COVID-19 pandemic ~~has~~and recent macroeconomic trends, including the current environment of inflationary pressures have created a high level of uncertainty. Due to this uncertainty, as well as difficulties with forecasting financial results historically, we maintained a full valuation allowance on our deferred tax assets at ~~September 30, 2021.~~March 31, 2022. The analysis that we prepared to determine the valuation allowance required significant judgment and assumptions regarding future market conditions as well as forecasts for profits, taxable income, and taxable income by jurisdiction. Due to the sensitivity of the analysis, changes to the assumptions in subsequent periods could have a material effect on the valuation allowance. See Note 13 to the condensed consolidated financial statements for more information related to income taxes.

We recorded a net ~~income~~loss of ~~$0.7~~$1.6 million for the three months ended ~~September 30, 2021~~March 31, 2022 compared to a net ~~income~~loss of ~~$1.0~~$0.7 million for the same period in ~~2020,~~2021, as higher operating expenses offset higher gross profits. Operating expenses were higher by ~~$1.1~~$1.9 million ~~as we spent more in all functional areas and intangible amortization expense for the intangible assets acquired from Smarteq.~~

~~We recorded a net loss of $0.2 million for the nine months ended September 30, 2021 compared~~due to ~~net income of $1.5 million for the same period in 2020, as the impact of higher operating~~restructuring expenses and ~~lower other income~~higher expenses for sales and ~~expense offset the higher gross profits from higher revenues. The increase in gross profit was a result of an increase in gross profit for both test & measurement products~~marketing related to travel and antennas and Industrial IoT devices. Operating expenses were higher by $2.7 million as we spent more in all functional areas, and we recorded intangible amortization expense for the intangible assets acquired from Smarteq and we higher restructuring expenses. Other income and expense was lower by $0.2 million because primarily because of lower interest income due to lower interest rates.trade shows.

Our primary source of liquidity is cash provided by operations, with short-term swings in liquidity supported by a significant balance of cash and short-term investments. The balance has fluctuated with cash from operations, acquisitions and divestitures, payment of dividends, and the repurchase of our common shares.

Within operating activities, we are historically a net generator of operating funds from our income statement ~~activities. During the nine months ended September 30, 2021, our balance sheet provided operating funds. In~~activities and during periods of expansion, we expect to use cash from our balance sheet.

Within investing activities, capital spending historically ranges between 2.0% and 4.0% of our revenues and the primary use of capital is for manufacturing, engineering, and product development. We historically have made significant transfers between investments and cash as we rotate our large cash balances and short-term investment balances between money market funds, which are accounted for as cash equivalents, and other investment vehicles. We have a history of supplementing our organic revenue with acquisitions of product lines or companies, resulting in significant uses of our cash and short-term investment balances from time to time. We ~~used $6.3 million, net of cash acquired for the purchase of Smarteq in April 2021. We~~ expect the historical trend for capital spending and the variability caused by moving money between cash and investments and periodic merger and acquisition activity to continue in the future.

Within financing activities, we have historically generated funds from the exercise of stock options and proceeds from the issuance of common stock through our Employee Stock Purchase Plan (“ESPP”). We have historically used funds to issue dividends and we periodically repurchase shares of our common stock through share repurchase programs. We used ~~$3.8 million for the repurchase of shares during the full year 2020 and~~ $3.2 million for the repurchase of shares during ~~the nine months ended September 30,~~ 2021. Share repurchases were funded with cash on hand. ~~The 2020 Repurchase Plan ended in September 2021 with the completion of $5.0 million of share repurchases.~~

At ~~September 30, 2021,~~March 31, 2022, our cash, cash equivalents, and investments were approximately ~~$32.5~~$27.7 million, and we had working capital of ~~$47.7~~$46.8 million. AsThroughout the COVID-19 pandemic, ~~continues to evolve,~~ we ~~are~~have proactively ~~managing~~managed our costs and our working capital in order to protect our financial position and maintain our workforce. Management believes our cash and investments provide adequate liquidity and working capital for the next twelve months from the date of this Quarterly Report on Form 10-Q to support our operations given our historic ability to generate free cash flow (cash flow from operations less capital spending) and our low level of ~~debt for the next twelve months from the date of this Quarterly Report on Form 10-Q.~~debt.

Operating activities ~~generated $6.4~~used $1.3 million of cash during the ~~nine~~three months ended ~~September 30, 2021.~~March 31, 2022. We ~~generated $4.3~~used $0.3 million of cash from our statement of operations and ~~$2.1~~$1.0 million from the balance sheet.

Operating activities generated ~~$10.6~~$1.7 million of cash during the ~~nine~~three months ended ~~September 30, 2020.~~March 31, 2021. We generated ~~$5.7~~$0.7 million of

cash from our statement of operations activities and ~~$4.9~~$1.0 million from the balance sheet. The balance sheet was a net source of cash as reductions in accounts receivable ~~and inventories~~ were partially offset by the reduction in accounts payable. Accounts receivable decreased by ~~$3.6~~$2.0 million primarily because revenues declined by ~~$4.0~~$3.5 million for the three months ended ~~September 30, 2020~~March 31, 2021 compared to the three months ended December 31, ~~2019.~~2020.

We used ~~$2.0~~$0.4 million for capital expenditures during the ~~nine~~three months ended ~~September 30,~~March 31, 2021.

Our investing activities used $7.7 million of cash during the nine months ended September 30, 2020. During the nine months ended September 30, 2020, redemptions and maturities of our investments provided $35.8 million in funds and we rotated $40.0 million of cash into new investments. We used $3.4 million for capital expenditures during the nine months ended September 30, 2020, primarily related to our new leased facility in Clarksburg, Maryland. We used cash of $1.4 million for leasehold improvements and other facility related equipment for the facility which opened in January 2020. During the nine months ended September 30, 2020 we received $1.0 million in tenant allowances for the Clarksburg facility. The tenant allowance is reflected in operating activities.

We used ~~$6.6~~$1.4 million in cash for financing activities during the ~~nine~~three months ended ~~September 30, 2021.~~March 31, 2022.

We used ~~$1.1~~$0.7 million for payroll taxes related to restricted stock awards and shares issued under the short-term incentive plan. On April 16, 2020, we received a $3.5 million paycheck protection program (“PPP”) loan from the Small Business Administration. Based upon subsequent guidance regarding PPP loan eligibility, we returned the funds on April 30, 2020.

~~None.~~Our material cash requirements from known contractual and other obligations primarily relate to non-cancelable purchase obligations.

We had purchase obligations of $19.6 million and $10.9 million at September 30, 2021 and December 31, 2020, respectively, for the purchase of inventory as well as for other goods and services in the ordinary course of business. Balances for purchases currently recognized as liabilities on the balance sheet are excluded.

~~We had a liability of $0.9 million and $0.8 million related to income tax uncertainties at September 30, 2021 and December 31, 2020, respectively. We do not know the~~Expected timing of ~~the settlement of this liability.~~those payments are as follows:

We use certain critical accounting policies as described in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates” of the ~~2020~~2021 Form 10-K. There have been no material changes in

any of our critical accounting policies since December 31, ~~2020.~~2021. See Note 1 to the condensed consolidated financial statements for a discussion of recent accounting pronouncements.

See our ~~2020~~2021 Form 10-K (Item 7A). As of ~~September 30, 2021,~~March 31, 2022, there have been no material changes in this information.

Our management evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of the end of the period covered by this report, our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities and Exchange Act, as amended (the “Exchange Act”) were effective to ensure that information we are required to disclose in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure, and that such information is recorded, processed, summarized, and reported within time periods specified in the rules and forms of the SEC.

In connection with the evaluation required by Rule 13a-15(d), management, with the participation of the Chief Executive Officer and Chief Financial Officer, has identified that there have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. We have not experienced any material impact to our internal controls over financial reporting during the COVID-19 pandemic, despite ~~transitioning nearly all of our administrative workforce to~~previously having a remote working environment asfor all non-production related employees and now having a ~~result of the COVID-19 pandemic.~~hybrid work environment. We are continually monitoring and assessing the impact of COVID-19 on our internal controls to minimize the impact to their design and operating effectiveness.

We may, from time to time, be the subject of various pending or threatened legal actions in the ordinary course of our business. All such matters are subject to many uncertainties and outcomes that are not predictable with assurance. To our knowledge, as of ~~September 30, 2021,~~March 31, 2022, there were no claims or litigation pending against the Company that would be reasonably likely to have a material adverse effect on our consolidated financial position, results of operations or liquidity.

See Item 1A of our ~~2020~~2021 Form 10-K. As of ~~September 30, 2021,~~March 31, 2022, there have been no material changes in this ~~information other than the risk factors below.~~information.

~~We face risks as a result of the acquisition of Smarteq Wireless Aktiebolag.~~

~~On April 30, 2021, we completed our acquisition of Smarteq Wireless Aktiebolag (“Smarteq”). As a result of the acquisition, we may face various risks, including, among others, the following:~~

We are dependent on the accuracy and completeness of statements and disclosures made by Smarteq and its representatives. We did not control and may be unaware of activities of Smarteq before the acquisition relating to, among other things, intellectual property; litigation or disputes including commercial and employment disputes; information security vulnerabilities; violations of laws, policies, rules and regulations; tax liabilities; and other liabilities.

The ongoing COVID-19 pandemic and related disruptions in our manufacturing and supply chains could have a continuing impact on the operations of our supply chain, which could adversely impact our sales and reputation.

We assemble our antennas in our facilities located in Bloomingdale, Illinois, and Tianjin, China, and test & measurement products at our facility in Clarksburg, Maryland. We may experience delays, disruptions, or capacity constraints (whether due to the non-renewal of our Tianjin, China facility lease, the COVID-19 pandemic or otherwise) or quality control problems at our assembly facilities, which could result in lower yields or delays of product shipments to our customers. In addition, we have limited in-house manufacturing capability. For some product lines, we outsource the manufacturing, assembly, and testing of printed circuit board subsystems. For other product lines, we purchase completed hardware platforms and add our proprietary software. While our suppliers have no unique capability, any failure by these suppliers to meet delivery commitments could cause delayed product delivery and potentially disrupt our supply chain and ability to accept new orders for products. For example, a significant number of our antennas are currently manufactured in China by contract manufacturers, and we are transitioning additional products currently manufactured in our Tianjin facility to contract manufacturers in China and elsewhere. Any disruption of our own or contract manufacturers' operations could cause delayed product delivery, which could negatively impact our sales, competitive reputation, and position. Moreover, if we do not accurately forecast demand for our products, we will have excess or insufficient parts to build our products, either of which could materially affect our operating results and may lead to obsolete inventory.

The spread of COVID-19 has impacted supply chains worldwide and may impact our ability to produce and sell products. During 2021, our operations have been impacted by global shortages of key components for our products, including resins, adhesives, plastics and electronics, and we have experienced long-lead times due to freight congestion and delays. Our business has been impacted by

~~increased costs in materials and logistics, as well as component part shortages. We currently anticipate that these cost increases and logistics constraints will continue through the balance of 2021.~~

Additionally, given the dynamic and prolonged nature of the COVID-19 pandemic, our operations, including our manufacturing facilities and those of our contract manufacturers, may slow again depending on whether there are future resurgences in infection rates and the imposition of additional containment measures. For example, early in the first quarter 2020, our Tianjin, China facility ceased production for approximately one month and our Chinese contract manufacturers ceased production for several weeks due to the COVID-19 outbreak in China, and our U.S. manufacturing facilities shut down for two weeks in April 2020 and operated at less than full capacity in May 2020.

In addition, in the event that for any reason our suppliers discontinue manufacturing materials used in our products, we would be forced to incur the time and expense of finding a new supplier or to modify our products in such a way that such materials were not necessary. Either of these alternatives could result in increased manufacturing costs and increased prices of our products.

In summary, in order to be successful, we must manage our operations to limit the cost of product production, accurately forecast demand for our products, avoid excess production and inventory that results in waste or obsolescence, dual source critical materials to avoid shortages and delays in shipping, build for manufacturability and avoid excessive quality issues.

~~Any of the risks described above could have a material adverse impact on our business, financial condition, results of operations, or prospects.~~

~~The following table provides the activity of the Company’s share repurchase program:~~

On November 4, 2020 the Company’s Board of Directors approved a share repurchase program pursuant to which the Company could repurchase up to $5.0 million of its common stock through the end of 2021. The Company repurchased 382,193 shares at an average price of $6.45 during the three months ended September 30, 2021 completing the share repurchases available under this program. The 2020 Repurchase Plan ended in September 2021 with the completion of $5.0 million of share repurchases.
