The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent liabilities at the date of the condensed consolidated financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from these estimates and assumptions.

On an ongoing basis, our management evaluates these estimates and assumptions, including those related to determination of standalone selling prices of our products and services, allowance for doubtful account and sales reserves, income tax valuations, stock-based compensation, goodwill, intangible assets and inventory valuations and recoverability. We base our estimates on historical data and experience, as well as various other factors that our management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities.

Due to the COVID-19 pandemic, there has been uncertainty and disruption in the global economy and financial markets. We are not aware of any specific event or circumstance that would require an update to our estimates or assumptions or a revision of the carrying value of our assets or liabilities. These estimates and assumptions may change as new events occur and additional information is obtained. As a result, actual results could differ materially from these estimates and assumptions.

At times, deposits held with financial institutions may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation (“FDIC”) and Securities Investor Protection Corporation (“SIPC”), of which both provide basic deposit coverage with limits up to $250,000 per owner. As of December 31, 2021, the Company had $19,136,924 in excess of the insurance limits. The Company has not experienced any such losses in these accounts. In Germany, the deposit insurance is €100,000 per bank, per customer. Bressner has funds on deposit in both Euro and U.S. dollar denominations of €463,248 (US$527,014) with banks in excess of the insurance limits.

In the years ended December 31, 2021 and 2020, approximately 36% and 24%, respectively, of net sales represent customers which are each greater than 10% of our consolidated annual revenue. This concentration is with two customers, disguise and Raytheon.

As of December 31, 2021 and 2020, approximately 56% and 64%, respectively, of net trade accounts receivables represent three customer balances which are each greater than 10% of our consolidated trade accounts receivable balance.

The Company made purchases from a certain supplier which represented greater than 10% of the Company’s vendor purchases on an annual basis. This vendor represented approximately 12.6% and 18.3% of purchases for the years ended December 31, 2021, and 2020, respectively.

Cash and cash equivalents consist of cash on deposit and money market accounts. The Company considers all highly liquid temporary cash investments with an initial maturity of three months or less when acquired to be cash equivalents. Management believes that the carrying amounts of cash equivalents approximate their fair value because of the short maturity period.

Short-term investments consist predominantly of commercial paper, corporate debt securities, U.S. Treasury securities, and asset-backed securities. The Company classifies short-term investments based on the facts and circumstances surrounding the investments at the time of purchase and evaluates such classification as of each balance sheet date. On December 31, 2021, all short-term investments were classified as available-for-sale.

Short-term investments are recorded at fair value with unrealized gains and losses included in accumulated other comprehensive income - a component of stockholders’ equity. Realized gains and losses are determined using the specific identification method and are included in other income (expense) in the consolidated statement of operations. The

Company evaluates its investments to determine whether those with unrealized loss positions are other than temporarily impaired. Impairments are considered to be other than temporary if they are related to deterioration in credit risk or if it is likely that the Company will sell the securities before recovery of their cost basis.

Accounts receivables are presented at net realizable value. This value includes an appropriate allowance for estimated uncollectible accounts to reflect any loss anticipated on the trade accounts receivable and unbilled receivables. Unbilled receivables include cost and gross profit earned in excess of billings. The allowance for doubtful accounts is an estimate to cover the losses resulting from the inability of customers to make payments on their outstanding balances and unbilled receivables. In estimating the required allowance, management considers the overall quality and aging of the accounts receivable, specific customer circumstances, current economic trends, and historical experience with collections. On December 31, 2021 and 2020, the allowance for doubtful accounts is $15,622 and $33,120, respectively.

Revenues earned in excess of related billings are recorded as an asset on the consolidated balance sheet as unbilled receivables. Unbilled receivables as of December 31, 2021 and 2020, were $0 and $106, respectively.

Inventories are valued at the lower of cost or net realizable value. The Company uses the average cost method for purposes of determining cost, which approximates the first-in, first-out method.

The Company establishes reserves on its inventories to write-down the carrying value of its estimated obsolete or excess inventories to estimated net realizable value based upon observations of historical usage and assumptions about future demand and market conditions. In addition, the Company considers changes in the market value of components in determining the net realizable value of its inventory. Inventory reserves are not typically reversed until the specific inventories are sold or otherwise disposed.

Actual demand, product mix and alternative usage may be lower than those that we project, and this difference could have a material adverse effect on our gross margin if inventory write-downs beyond those initially recorded become necessary. Alternatively, if actual demand, product mix and alternative usage are more favorable than those we estimated at the time of such a write-down, our gross margin could be favorably impacted in future periods.

Property and equipment, other than leasehold improvements, are recorded at cost and depreciated using the straight-line method over the estimated useful lives of the assets, generally from two to seven years. Leasehold improvements are recorded at cost and are amortized using the straight-line method over the shorter of the remaining lease term or the estimated useful life of the related asset. Tooling and test equipment includes capitalized labor costs associated with the development of the related tooling and test equipment. Costs incurred for maintenance and repairs are expensed as incurred, and expenditures for major replacements and improvements are capitalized. Upon retirement or sale, the cost and related accumulated depreciation and amortization of disposed assets are removed from the accounts and any resulting gain or loss is included in other (expense) income, net.

Goodwill represents the excess of the purchase price paid over the fair value of the net assets acquired in business combinations. Goodwill is not amortized but is tested for impairment at least annually and when we deem that a triggering event has occurred. The Company reviews goodwill for impairment annually on December 31^st. The Company completed its annual assessment for goodwill impairment and determined that goodwill is not impaired as of December 31, 2021, and no adjustment was required.

We evaluate our intangible and long-lived assets for impairment when events or circumstances arise that indicate our intangible and long-lived assets may be impaired. Indicators of impairment include, but are not limited to, a significant deterioration in overall economic conditions, a decline in our market capitalization, the loss of significant business, significant decreases in funding for our contracts, or other significant adverse changes in industry or market conditions. The Company

completed its qualitative assessment for impairment in December 2021, and determined that there was no impairment as of December 31, 2021. Though there were indicators of impairment attributable to the COVID-19 pandemic that directly impacted our business, as a result of management’s cost containment efforts, raising cash, minimizing working capital requirements and a focus on profitability, during the year the Company improved its financial stability and thus determined that there is no impairment of its intangible and long-lived assets. There can be no assurance; however, that market conditions will not change or demand for the Company’s products will continue, which could result in an impairment of intangible and long-lived assets in the future.

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. These tiers include:

The carrying value of financial instruments including cash and cash equivalents, accounts receivable, and accounts payable and accrued expenses, and other liabilities approximate fair value due to the short-term nature of these instruments. Assets and liabilities assumed in the acquisition of the Ion software, Concept Development Inc., and Bressner Technology GmbH were recorded at fair value based upon the Company’s market assumptions which approximated carrying value due to the short-term nature of the instruments. The carrying amounts of the Company’s short-term investments, notes payable and Bressner’s existing lines of credit and notes payable approximate their fair values at the stated interest rates and are reflective of the prevailing market rates.

The Company’s revenues are recognized in accordance with ASC 606, Revenue from Contracts with Customers for which the Company’s performance obligations are satisfied over time as work is performed or at a point in time. The majority of the Company’s revenue is recognized at a point in time when products ship and control is transferred to the customer. The Company determines revenue recognition through the following steps: (i) identification of the contract with a customer; (ii) identification of the performance obligations in the contract; (iii) determination of the transaction price; (iv) allocation of the transaction price to the performance obligations in the contract; and (v) recognition of revenue when, or as, a performance obligation is satisfied.

The Company’s contracts are executed through a combination of written agreements along with purchase orders with all customers including certain general terms and conditions. Generally, purchase orders entail products, quantities and prices, which define the performance obligations of each party and are approved and accepted by the Company. The Company’s contracts with customers typically do not include extended payment terms. Payment terms vary by contract type and type of customer and generally range from 30 to 60 days from invoice. Additionally, taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by the Company from a customer and deposited with the relevant government authority, are excluded from revenue.

The transaction price is determined based on the consideration to which the Company will be entitled in exchange for transferring goods or services to the customer adjusted for estimated variable consideration, if any. Variable consideration may include discounts, rights of return, refunds, and other similar obligations. The Company allocates the transaction price to each distinct product and service based on its relative standalone selling price. The standalone selling price for products primarily involves the cost to produce the deliverable plus the anticipated margin and for services is estimated based on the Company’s approved list price.

In the normal course of business, the Company does not accept product returns unless the items are defective as manufactured. The Company establishes provisions for estimated returns and warranties. In addition, the Company does not typically provide customers with the right to a refund and does not transact for noncash consideration.

Customer agreements include one vendor managed inventory program. The Company recognizes revenue under this arrangement when all of the following criteria are met: (i) the goods have been identified separately as belonging to the customer; (ii) the goods are ready for physical shipment to the customer; (iii) the Company does not have the ability to direct the goods to another customer; and (iv) the arrangement was requested by the customer and that the customer has sufficiently explained a substantial business purpose for the arrangement. Management also considers whether the customer's custodial risks are insured and whether modifications to the Company's normal billing and credit terms were required.

The Company recorded revenue from product sales that are held in vendor managed inventory under this agreement of $12,544,422 and $6,692,752 for the years ended December 31, 2021 and 2020, respectively. As of December 31, 2021 and 2020, $1,128,033 and $1,482,186, respectively, of products sold through those dates were held by the Company in the vendor management program.

Revenues on certain fixed-price contracts where we provide engineering services, prototypes and completed products are recognized over time based upon the output method as milestones are met and value is delivered to the customer, which depicts the Company’s progress toward fulfilling its performance obligations. These services require that we perform significant, extensive, and complex design, development, modification or implementation of our customers’ systems. Performance will often extend over long periods of time, and our right to receive future payment depends on our future performance in accordance with the agreement. If changes occur in delivery, productivity or other factors used in developing the estimates of costs or revenues, we revise our cost and revenue estimates, which may result in increases or decreases in revenues and costs, and such revisions are reflected in earnings in the period in which the revision becomes known. There were no significant unbilled or incomplete milestone projects as of December 31, 2021.

The Company’s operating segment revenues, disaggregated by primary geographic market, which is determined based on a customer’s geographic location, for the years ended December 31, 2021 and 2020, are as follows:

	For the Year Ended December 31, 2021						For the Year Ended December 31, 2020
Entity:	Domestic		International		Total		Domestic		International		Total
Customized computers and flash arrays	$	20,685,839	$	17,806,165	$	38,492,004	$	22,822,064	$	10,827,954	$	33,650,018

	$	20,695,952	$	41,286,152	$	61,982,104	$	22,914,575	$	28,980,813	$	51,895,388

The Company offers product warranties that extend for one or two years from the date of sale. Such warranties are considered assurance-type warranties; therefore, they would not be deemed to be a separate performance obligation under ASC 606. Such warranties require the Company to repair or replace defective product returned to the Company during the warranty period at no cost to the customer. The Company records an estimate for warranty‑related costs based on its historical and estimated future product return rates and expected repair or replacement costs (Note 8).

While such costs have historically been within management’s expectations and the provisions established, unexpected changes in failure rates could have a material adverse impact on the Company, requiring additional warranty reserves and could adversely affect the Company’s gross profit and gross margins.

The Company offers customers extended warranties beyond the standard one-year warranty on the product. The extended warranties are considered service-type warranties and would be considered as a separate performance obligation under ASC 606. The Company is the primary obligor and revenue is recognized on a gross basis ratably over the term of the extended warranty. The customer can purchase extended warranties from one to five years, in the bronze, silver or gold categories. This entails hardware repair or replacement, shipping methods on how the warranties will be returned/delivered, response times and hours of operations to receive support. The value of warranties sold for years ended December 31, 2021 and 2020, were $76,502 and $373,847, respectively.

The revenue that was recognized for the warranties sold for the years ended December 31, 2021 and 2020, were $306,373 and $401,915, respectively. The Company does have recourse with some of its suppliers that offer more than a one-year guarantee on parts, but this is not standard. The few that offer greater than a year warranty, the Company may be able to recover the cost of the part from the manufacturer for the failed part. The amounts of these costs vary in a wide range, but are not material, due to the infrequency of failure. As of December 31, 2021 and 2020, deferred revenue totaled $177,898 and

$407,768, respectively. The Company expects to recognize approximately $177,898 of unearned revenue amounts from 2022 through 2024.

The Company's shipping and handling costs are included in cost of goods sold for all periods presented.

We operate primarily in the United States. Foreign sales of products and services are primarily denominated in U.S. dollars. We also conduct business outside the United States through our foreign subsidiary in Germany, where business is largely transacted in non-U.S. dollar currencies particularly the Euro, which is subject to fluctuations due to changes in foreign currency exchange rates. Accordingly, we are subject to exposure from changes in the exchange rates of local currencies. Foreign currency transaction gains and losses are recorded in other income (expense), net in the consolidated statements of operations.

OSS GmbH operates as an extension of OSS’ domestic operations. The functional currency of OSS GmbH is the Euro. Transactions denominated in currencies other than the functional currency are remeasured to the functional currency at the average exchange rate in effect during the period. At the end of each reporting period, monetary assets and liabilities are remeasured using exchange rates in effect at the balance sheet date. Non-monetary assets and liabilities are remeasured at historical exchange rates. Consequently, changes in the exchange rates of the currencies may impact the translation of the foreign subsidiaries’ statements of operations into U.S. dollars, which may in turn affect our consolidated statement of operations. The resulting foreign currency translation adjustments are recorded as a separate component of accumulated other comprehensive income (loss) in the consolidated balance sheets.

We may employ derivatives to manage certain currency market risks through the use of foreign exchange forward contracts. We do not use derivatives for trading or speculative purposes. Our derivatives are designated as a hedge of a forecasted transaction or of the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). We hedge a portion of the exchange risk involved in anticipation of highly probable foreign currency-denominated transactions. In anticipation of these transactions, we enter into foreign exchange contracts to provide currency at a fixed rate. As of December 31, 2021 and 2020, Bressner had no foreign exchange contract outstanding.

Unrealized gains on derivatives designated as cash flow hedges are recorded at fair value as assets, and unrealized losses on derivatives designated as cash flow hedges are recorded at fair value as liabilities. For derivative instruments designated as cash flow hedges, the effective portion is reported as a component of accumulated OCI until reclassified into interest expense in the same period the hedged transaction affects earnings. The gain or loss on the ineffective portion is recognized as “Other (expense) income, net” in the consolidated statements of operations in each period.

The Company accounts for employee and director share-based compensation in accordance with the provisions of ASC Topic 718 “Compensation – Stock Compensation”. Under ASC 718, share-based compensation cost is measured at the grant date, based on the calculated fair value of the award, and is recognized as an expense over the employee’s requisite service period (generally the vesting period of the equity grant).

All transactions in which goods or services are the consideration received for the issuance of equity instruments to non-employees are accounted for based on the equivalent fair value of the consideration received or the fair value of the equity instrument issued, whichever is more reliably measurable on the grant date. The measurement date used to determine the estimated fair value of the equity instrument issued is the earlier of the date on which the third-party performance is complete or the date on which it is probable that performance will occur.

Employee and director stock-based compensation expense recognized during the period is based on the value of the portion of stock-based payment awards that is ultimately expected to vest during the period. Given that stock-based compensation expense recognized in the accompanying consolidated statements of operations is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. The Company’s estimated average forfeiture rates are based on historical forfeiture experience and estimated future forfeitures.

Compensation cost for stock awards, which include restricted stock units (“RSUs”), is measured at the fair value on the grant date and recognized as expense, net of estimated forfeitures, over the related service period. The fair value of stock awards is based on the quoted price of our common stock on the grant date.

The estimated fair value of common stock option awards is calculated using the Black-Scholes option pricing model. The Black-Scholes model requires subjective assumptions regarding future stock price volatility and expected time to exercise, along with assumptions about the risk-free interest rate and expected dividends, all of which affect the estimated fair values of the Company’s common stock option awards. Given a lack of historical stock option exercises, the expected term of options granted is calculated as the average of the weighted vesting period and the contractual expiration date of the option. This calculation is based on a method permitted by the Securities and Exchange Commission in instances where the vesting and exercise terms of options granted meet certain conditions and where limited historical exercise data is available. The expected volatility is based on the historical volatility of the common stock of comparable public companies that operate in similar industries as the Company.

The risk-free rate selected to value any particular grant is based on the U.S. Treasury rate that corresponds to the expected term of the grant effective as of the date of the grant. The expected dividend assumption is based on the Company’s history and management’s expectation regarding dividend payouts. Compensation expense for common stock option awards with graded vesting schedules is recognized on a straight-line basis over the requisite service period for the last separately vesting portion of the award, provided that the accumulated cost recognized as of any date at least equals the value of the vested portion of the award.

If there are any modifications or cancellations of the underlying vested or unvested stock-based awards, the Company may be required to accelerate, increase or cancel any remaining unearned stock-based compensation expense, or record additional expense for vested stock-based awards. Future stock-based compensation expense and unearned stock- based compensation may increase to the extent that the Company grants additional common stock options or other stock-based awards.

We utilize the acquisition method of accounting for business combinations and allocate the purchase price of an acquisition to the various tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. We primarily establish fair value using the income approach based upon a discounted cash flow model. The income approach requires the use of many assumptions and estimates including future revenues and expenses, as well as discount factors and income tax rates. Other estimates include:

While we use our best estimates and assumptions as part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the business acquisition date, our estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the purchase price allocation period, which is generally one year from the business acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill.

For changes in the valuation of intangible assets between preliminary and final purchase price allocation, the related amortization is adjusted in the period it occurs. Subsequent to the purchase price allocation period any adjustment to assets acquired or liabilities assumed is included in operating results in the period in which the adjustment is determined. Should we issue shares of our common stock in an acquisition, we will be required to estimate the fair value of the shares issued. See Note 7.

Debt discounts, which originate from the relative fair value of warrants issued in connection with notes payable and related-party notes payable, are recorded against the noted payable and related-party notes payable in the accompanying consolidated balance sheets.

Amortization of the debt discounts are calculated using the straight-line method over the term of the applicable notes which approximates the effective interest method and are recorded in interest expense in the accompanying consolidated statements of operations.

Advertising costs are expensed as incurred and included in marketing and selling expense in the accompanying consolidated statements of operations. Advertising costs for the years ended December 31, 2021 and 2020, were $356,874 and $377,105, respectively.

Research and development expenditures are expensed in the period incurred. Research and development expenses primarily consist of salaries, benefits and stock-based compensation, as well as consulting expenses and allocated facilities and other overhead costs. Research and development activities include the development of new technologies, features and functionality in support of the Company’s products and customer needs.

The Company utilizes the asset and liability method of accounting for income taxes. Under this method, deferred tax assets and liabilities are determined based on the difference between the consolidated financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

Under ASC Topic 740, the impact of an uncertain income tax position on the income tax return must be recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Additionally, ASC Topic 740 provides requirements for derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company’s policy is to recognize interest and/or penalties related to income tax matters in income tax expense.

The Company files income tax returns in the U.S. federal jurisdiction, California and various other state jurisdictions, and Germany. The Company has elected to treat the tax effect of Global Intangible Low Tax Income (“GILTI”) as a current-period expense when occurred. The Company does not foresee material changes to its gross liability of uncertain tax positions within the next twelve months.

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) was signed into law in March 2020. The CARES Act lifts certain deduction limitations originally imposed by the Tax Cuts and Jobs Act of 2017 (2017 Tax Act). Corporate taxpayers may carryback net operating losses (“NOLs”) originating during 2018 through 2020 for up to five years, which was not previously allowed under the 2017 Tax Act. The CARES Act also eliminates the 80% of taxable income limitations by allowing corporate entities to fully utilize NOL carryforwards to offset taxable income in 2018, 2019 or 2020. Taxpayers may generally deduct interest up to the sum of 50% of adjusted taxable income plus business interest income (30% limit under the 2017 Tax Act) for tax years beginning January 1, 2019 and 2020. The CARES Act allows taxpayers with alternative minimum tax credits to claim a refund in 2020 for the entire amount of the credits instead of recovering the credits through refunds over a period of years, as originally enacted by the 2017 Tax Act.

In addition, the CARES Act raises the corporate charitable deduction limit to 25% of taxable income and makes qualified improvement property generally eligible for 15-year cost-recovery and 100% bonus depreciation. The enactment of the CARES Act resulted in two adjustments to our income tax provision for the year ended December 31, 2020, relating to a projected 2018 NOL utilization and tax benefits from NOL carrybacks. We have recorded a benefit of $41,561 in our income tax provision for the year ended December 31, 2020, related to the CARES Act.

Interest expense consists primarily of interest associated with the Company’s issued debt including the amortization of debt discounts. The Company recognizes the amortization of debt discounts and the amortization of interest costs using a straight-line method which approximates the effective interest method.

Basic net income (loss) per share is calculated by dividing net income (loss) by the weighted-average common shares outstanding during the period. Diluted net income (loss) per share is calculated by dividing the net income (loss) by the weighted-average shares and dilutive potential common shares outstanding during the period. Dilutive potential shares consist of dilutive shares issuable and the exercise or vesting of outstanding stock options, restricted stock units and warrants, respectively, computed using the treasury stock method. During a period where a net loss is incurred, dilutive potential shares are excluded from the computation of dilutive net loss per share, as inclusion is anti-dilutive.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 is effective for the Company for fiscal years beginning after December 15, 2021, and interim periods within fiscal year 2023. Lessees may use either the modified retrospective method (reflected retrospectively to each prior reporting period presented in the consolidated financial statements) or the transition method (reflected at the beginning of the period of adoption). Lessees may not apply a full retrospective transition approach. The Company is currently evaluating the impact of adopting ASU 2016-02 on its consolidated financial statements and disclosures. Based on its preliminary analysis, management expects the Company’s assets and liabilities to increase by the present value of the lease payments of approximately $805,000 with implementation as of January 1, 2022, using the transition method.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 amends the guidance on the impairment of financial instruments. This update adds an impairment model (known as the current expected credit losses model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes, as an allowance, its estimate of expected credit losses. In November 2019, ASU 2016-13 was amended by ASU 2019-10 that changed the effective date of ASU 2016-13 to fiscal years beginning after December 15, 2022, with early adoption permitted. Further, the ASU clarifies that operating lease receivables are not within the scope of ASC Subtopic 326-20 and should instead be accounted for under the new leasing standard, ASC 842. The Company is currently evaluating the impact of adopting ASU 2016-13 on its consolidated financial statements and related disclosures.
