In our opinion, the accompanying unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) necessary to present fairly our financial position, results of operations, and cash flows for the interim periods presented. We have presented financial statements in accordance with the rules and regulations of the Securities and Exchange Commission (“SEC”). Therefore, such financial statements do not include all disclosures required by accounting principles generally accepted in the United States of America. In preparing these unaudited consolidated financial statements, the Company has evaluated events and transactions for potential recognition or disclosure through the date the unaudited consolidated financial statements were issued by filing with the SEC.

ONE STOP SYSTEMS, INC. (OSS)

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

For the Three Month Periods Ended March 31, 2022 and 2021

NOTE 1 – THE COMPANY AND BASIS OF PRESENTATION

Nature of Operations

One Stop Systems, Inc. (“we,” “our,” “OSS,” or the “Company”) was originally incorporated as a California corporation in 1999, after initially being formed as a California limited liability company in 1998. On December 14, 2017, the Company was reincorporated as a Delaware corporation in connection with its initial public offering. The Company designs, manufactures, and markets specialized high-performance computing modules and systems, which are designed to target edge computing deployments. The Company markets its products to manufacturers of automated equipment used for media and entertainment, medical, industrial, and military applications.

During the year ended December 31, 2015, the Company formed a wholly-owned subsidiary in Germany, One Stop Systems, GmbH (“OSS GmbH”). In July 2016, the Company acquired Mission Technologies Group, Inc. (“Magma”) and its operations.

On August 31, 2018, the Company acquired Concept Development Inc. (“CDI”) located in Irvine, California. CDI specializes in the design and manufacture of custom high-performance computing systems for airborne in-flight entertainment and networking systems. CDI has been fully integrated into the core operations of OSS as of June 1, 2020.

On October 31, 2018, OSS GmbH acquired 100% of the outstanding stock of Bressner Technology GmbH, a Germany limited liability company located near Munich, Germany (“Bressner”). Bressner provides standard and customized servers, panel PCs, and PCIe expansion systems. Bressner also provides manufacturing, test, sales and marketing services for customers throughout Europe.

The accompanying consolidated financial statements include the accounts of OSS, which include the acquisition of CDI, and its wholly owned subsidiary, OSS GmbH, which also includes the acquisition of Bressner. Intercompany balances and transactions have been eliminated in consolidation.

The negative impact of the COVID-19 pandemic and the impact on the global economy and capital markets resulting from the geopolitical instability caused in part by the ongoing military conflict between Russia and Ukraine have contributed to global supply chain issues and economic uncertainty, which has negatively affected our operations. For example, the Company’s revenue growth during fiscal year 2020 slowed due to the effects of COVID-19 and, although it rebounded in 2021, it has not yet fully recovered, particularly in its media and entertainment business.

Currently, we are experiencing increased pricing, longer lead-times, unavailability of product and limited supplies, protracted delivery dates, changes in minimum order quantities to secure product, and/or shortages of certain parts and supplies that are necessary components for the products and services we offer to our customers. As a result, the Company is carrying increased inventory balances to ensure availability of necessary products and to secure pricing. Additionally, products that are in the “work-in-process” stage and our inventory of finished goods have increased due to the timing and availability of certain componentry necessary to complete our products.

These global issues are also impacting some of our customers, who are experiencing downturns or uncertainty in their own business operations and revenue, and as a result, these customers may need to decrease or delay their technology spending, requested pricing concessions or payment extensions, or seek to renegotiate their contracts.

As a result of these global issues, it has been difficult to accurately forecast our revenues or financial results, especially given that the near and long term impact of the pandemic and geopolitical issues. In addition, while the potential impact and duration of these issues on the economy and our business may be difficult to assess or predict, these world events have resulted in, and may continue to result in, significant disruption of global financial markets,

11

and may reduce our ability to access additional capital, which could negatively affect our liquidity in the future. Our results of operations could be materially below our forecasts as well, which could adversely affect our results of operations, disappoint analysts and investors, or cause our stock price to decline.

Furthermore, a decrease in orders in a given period could negatively affect our revenues in future periods. These global issues and events may also have the effect of heightening many risks associated with our customers and supply chain. We may take further actions that alter our operations as may be required by federal, state, or local authorities from time to time, or which we determine are in our best interests. In addition, we may decide to postpone or abandon planned investments in our business in response to changes in our business, which may impact our ability to attract and retain customers and our rate of innovation, either of which could harm our business.

Management plans with respect to the above are to continue their efforts towards responding to the changing economic landscape, to continue to control costs, conserve cash, strengthen margins, and improve company-wide execution.

Basis of Presentation

The accompanying consolidated financial statements have been prepared on an accrual basis of accounting in accordance with United States Generally Accepted Accounting Principles (“U.S. GAAP”), as set forth in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”).

The unaudited consolidated financial statements herein have been prepared by the Company pursuant to the rules and regulations of the SEC. The accompanying interim unaudited consolidated financial statements have been prepared under the presumption that users of the interim financial information have either read or have access to the audited consolidated financial statements for the latest year ended December 31, 2021. Accordingly, note disclosures which would substantially duplicate the disclosures contained in the December 31, 2021, audited consolidated financial statements have been omitted from these interim unaudited consolidated financial statements. The Company’s management has evaluated all subsequent events and transactions through the date of filing this report.

In the opinion of management, all adjustments considered necessary for a fair presentation have been included in the accompanying condensed consolidated financial statements. Operating results for the three months ended March 31, 2022, are not necessarily indicative of the results that may be expected for the year ending December 31, 2022. For further information, refer to the audited consolidated financial statements and notes for the year ended December 31, 2021, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 24, 2022.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

There have been no changes to our accounting policies disclosed in our audited consolidated financial statements and the related notes for the year ended December 31, 2021, except for the addition of a definition of, and description of our policy for accounting for leases in accordance with the adoption of ASU No. 2016-02, Leases (“ASU 2016-02”) as follows:

Leases

In February 2016, the FASB issued ASU No. 2016-02, “Leases”, which sets out the principles for the recognition, measurement, presentation, and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases. A lease must be classified as a finance lease if any of the following criteria are met: the lease transfers ownership of the asset by the end of the lease term, the lease contains an option to purchase the asset that is reasonably certain to be exercised, the lease term is for a major part of the remaining useful life of the asset or the present value of the lease payments equals or exceeds substantially all of the fair value of the asset. A lease is classified as an operating lease if it does not meet any of these criteria. The Company determines if a contract is or contains a lease at inception or modification of a contract. A contract is or contains a lease if the contract conveys

12

the right to control the use of an identified asset for a period in exchange for consideration. Control over the use of the identified asset means the lessee has both (a) the right to obtain substantially all of the economic benefits from the use of the asset and (b) the right to direct the use of the asset. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease.

Right-of-use assets and liabilities are initially measured at cost, which primarily comprises the initial amount of the lease liability, plus any initial direct costs incurred, consisting mainly of brokerage commissions, less any lease incentives received. All right of use assets are reviewed for impairment. The lease liability is initially measured at the present value of future minimum lease payments over the expected lease term at the commencement date of each lease. The Company measures and records a right-of-use asset and lease liability based on the discount rate implicit in the lease, if known. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor's estimated residual value or the amount of the lessor's deferred initial direct costs.

In these cases where the discount rate implicit in the lease is not known, the Company measures the right-of-use assets and lease liabilities using a discount rate equal to the Company's incremental borrowing rate it pays on current debt instruments or would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms.

The Company and its subsidiary have no leases classified as finance leases. The Company and its subsidiary currently lease plant, office facilities and equipment under operating leases expiring through August 2024. As of March 31, 2022, the weighted average remaining lease term for our operating leases was 32 months. The weighted average discount rate for our operating leases was 12.3%.

The Company’s lease agreements may include options to extend the lease following the initial term. On a case-by-case basis, the Company’s management determines if it is reasonably certain to exercise the renewal option; such renewal options were included in determining the initial lease term.

We elected the package of practical expedients in transition for leases that commenced prior to January 1, 2022, and therefore did not reassess (i) whether any expired or existing contracts are, or contain, leases, (ii) the lease classification for any expired or existing leases, and (iii) initial direct costs for any existing leases. We elected to use hindsight for transition when considering judgments and estimates such as assessments of lease options to extend, or terminate, a lease, or to purchase the underlying asset. As result of the adoption of ASC 842, the Company recognized an accumulative adjustment to beginning retained earnings for the 2022 fiscal year of $44,533.

For all asset classes, we elected to (i) not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less and (ii) not separate non-lease components from lease components, and we have accounted for combined lease and non-lease components as a single lease component. Variable lease payments associated with the Company’s leases are recognized upon occurrence of the event, activity, or circumstance in the lease agreement on which those payments are assessed. For those leases that are subsequently modified for terms, such changes may require a remeasurement of the lease liability.

Lease expense for operating leases consists of the lease payments plus any initial direct costs, primarily brokerage commissions, and is recognized on a straight-line basis over the lease term. Included in lease expense are any variable lease payments incurred in the period that were not included in the initial lease liability. Lease expense for finance leases consists of the amortization of the right-of-use asset on a straight-line basis over the lease term and interest expense determined on an amortized cost basis. The lease payments are allocated between a reduction of the lease liability and interest expense.

13

Use of Estimates

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.

As of March 31, 2022, we had $3,568,566 in net deferred tax assets (“DTAs”). These DTAs include approximately $7,100,000 related to net operating loss carryforwards that can be used to offset taxable income in future periods and reduce our income taxes payable in those future periods. At this time, we consider it more likely than not that we will have sufficient taxable income in the future that will allow us to realize these DTAs. However, it is possible that certain economic conditions may decrease the likelihood that we will have sufficient taxable income in the future. Therefore, unless we are able to generate sufficient taxable income from our operations, a substantial valuation allowance to reduce our U.S. DTAs may be required, which would materially increase our expenses in the period the allowance is recognized and may have a material adverse effect on our results of operations and statement of financial condition.

On March 11, 2021, Congress passed, and the President signed into law, the American Rescue Plan Act, 2021 (the “ARP”), which includes certain business tax provisions. At this point, we do not believe that these changes will have a material impact on our income tax provision for 2022. We will continue to evaluate the impact of new legislation on our financial position, results of operations, and cash flows.

The U.S. Tax Cuts and Jobs Act (“TCJA”) was signed into law on December 22, 2017. Guidance continues to be issued clarifying the application of this legislation and new proposed legislation known as Build Back Better is under consideration within both houses of U.S. Congress. Significant business and international provisions have been proposed in various versions of the framework of the bill that could increase our total tax expense. We cannot predict the overall impact that the additional guidance and proposed changes may have on our business. Some jurisdictions have raised tax rates and it is reasonable to expect that other global taxing authorities will be reviewing current legislation for potential modifications in reaction to the implementation of U.S. tax legislation, current economic conditions, and COVID-19 response costs.

Due to the COVID-19 pandemic, economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability due to the ongoing military conflict between Russia and Ukraine supply chain issues, our business, financial condition and results of operations could be materially adversely affected by any negative impact from these events. 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 as of the date of this Quarterly Report on Form 10-Q. 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.

Recent Accounting Pronouncements

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

14

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.

Notes Payable

In April 2019, the Company borrowed an aggregate of $350,000 from three individuals for a two-year period at an interest rate of 9.5%, which required the Company to make monthly principal and interest payments of $16,100 per month. These loans were secured by the assets of the Company. In connection with these loans, the Company issued to the noteholders warrants to purchase shares of the Company’s common stock in an amount equal to 10% of the original principal at a price per share equal to $2.15. Accordingly, the Company issued to the noteholders warrants to purchase an aggregate of 16,276 shares of the Company’s common stock at an exercise price of $2.15 per share. The relative fair value of each warrant was $0.90. The relative fair value of warrants was estimated using Black-Scholes with the following weighted-average assumptions: fair value of the Company’s common stock at issuance of $2.15 per share; five year contractual term; 44.60% volatility; 0.0% dividend rate; and a risk-free interest rate of 2.307%. The total relative fair value of the warrants issued is $14,037. These loans have matured, and all balances have been paid in full. As such, the balances outstanding as of March 31, 2022 and December 31, 2021, were $0.

Notes Payable – Related Parties

In April 2019, the Company borrowed an aggregate of $1,150,000 from three individuals who serve on the Company’s board of directors for a two-year period at an interest rate of 9.5%, which required the Company to make monthly principal and interest payments of $52,900 per month. These loans were secured by the assets of the Company. In connection with these loans, the Company issued to the noteholders warrants to purchase shares of the Company’s common stock in an amount equal to 10% of the original principal at a price per share equal to $2.15. Accordingly, the Company issued to the noteholders warrants to purchase an aggregate 53,490 shares of the Company’s common stock at an exercise price of $2.15 per share. The relative fair value of each warrant was $0.90. The relative fair value of warrants was estimated using Black-Scholes with the following weighted-average assumptions: fair value of the Company’s common stock at issuance of $2.15 per share; five year contractual term; 42.60% volatility; 0.0% dividend rate; and a risk-free interest rate of 2.3067%. The relative fair value of warrants issued is $46,121. These loans have matured, and all balances have been paid in full. As such, the balances outstanding as of March 31, 2022 and December 31, 2021 were $0.

Debt Discount

The relative fair value of warrants issued in connection with the notes payable described above were recorded as debt discount, decreasing notes payable and related-party notes payable and increasing additional paid-in-capital on the accompanying consolidated balance sheets. The debt discounts are being amortized to interest expense over the term of the corresponding notes payable using the straight-line method, which approximates the effective interest method. Amortization of debt discounts of $0 and $7,519 were recognized as interest expense for the three month periods ended March 31, 2022 and 2021, respectively.

Paycheck Protection Program Loan

On April 28, 2020, the Company received authorization pursuant to the Paycheck Protection Program (“PPP”) of the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) as administered by the U.S. Small Business Administration (the “SBA”) for a “PPP” loan. On May 11, 2020, the loan was funded, and the Company received proceeds in the amount of $1,499,360 (the “PPP Loan”).

The PPP Loan, which took the form of a two-year promissory note (the “PPP Note”), was scheduled to mature on April 28, 2022 and bore interest at a rate of 1.0% per annum. Monthly principal and interest payments, less the amount of any potential forgiveness (discussed below), was initially to commence on October 28, 2020. The Company did not provide any collateral or guarantees for the PPP Loan, nor did the Company pay any facility charge to obtain the PPP Loan. The PPP Note provided for customary events of default, including, among others, those relating to failure to make payment, breaches of any term, obligation, covenant, or condition contained in the PPP Note and payment of unauthorized expenses or use of proceeds contrary to CARES Act rules.

The Company submitted an application with the lender to forgive the PPP Loan, in accordance with SBA Procedural Notice, Control No. 5000-20057, effective as of October 2, 2020. On May 3, 2021, the Company received notification from the SBA that its PPP Loan of $1,499,360, plus accrued interest of $14,994, had been fully forgiven and such amount has been recognized as other income in the consolidated statement of operations.

Senior Secured Convertible Note

On April 20, 2020, the Company entered into a Securities Purchase Agreement with an institutional investor, providing for the issuance by the Company of Senior Secured Convertible Promissory Notes with a principal face value of up to $6,000,000. The notes are, subject to certain conditions, convertible into shares of the Company’s common stock, par value $0.0001 per share, at an initial conversion price per share of $2.50. Notes issued under the Securities Purchase Agreement had a 10% original issue discount.

At the initial closing of this offering, the Company issued notes in the principal amount of $3,000,000 with a 10% original issue discount resulting in an aggregate purchase price of $2,700,000 at the initial closing. The notes bore no interest rate (except upon event of default) and, unless earlier converted or redeemed, were scheduled to mature on April 1, 2022.

19

Pursuant to the Securities Purchase Agreement, the Company had the right to consummate additional closings of up to an additional $3,000,000, subject to the prior satisfaction of certain closing conditions. This right expired effective April 20, 2021, and the Company may no longer consummate additional closings under the Securities Purchase Agreement.

The notes were convertible at any time, in whole or in part, at the option of the investors, into shares of Company common stock at the initial conversion price of $2.50 per share. The conversion price was subject to adjustment for the issuances of securities at a price below the conversion price then in effect and for stock splits, combinations or similar events. If immediately following the close of business on the nine month anniversary of the issuance date of each note, the conversion price then in effect exceeded 135% of the volume weighted average price VWAP (the “Market Price”), the initial conversion price under any such note would be automatically lowered to the Market Price.

Commencing July 1, 2020, the Company made monthly amortization payments equal to 1/22nd of the initial principal, any accrued and unpaid interest and late charges and any deferred or accelerated amount, of such note, which may be satisfied in cash at a redemption price equal to 105% of such installment amount (110% of such installment amount on notes issued at additional closings). The remaining balance of the notes of $2,590,909 was converted into Company common stock on March 31, 2022.

Subject to the satisfaction of certain equity conditions set forth in the notes, installment amounts could be satisfied in shares of our common stock, with such installment conversion at a conversion price equal to the lower of (i) the conversion price then in effect; and (ii) the greater of (x) the floor price of $1.00 (80% of the Nasdaq market price at date of purchase agreement) and (y) the lower of (I) 82.5% the volume weighted average price of our common stock on the trading day immediately before the applicable installment date and (II) 82.5% of the quotient of (A) the sum of the volume weighted average price of our common stock for each of the three (3) trading days with the lowest volume weighted average price of our common stock during the twenty (20) consecutive trading day period ending and including the trading day immediately prior to the applicable installment date, divided by (B) three (3). Shares of our common stock to be issued with respect to any such installment would be pre-delivered on the second trading day after the applicable installment notice date (as defined in the notes) with a true-up on the applicable installment date. The market value of any installment amount below the floor price would be cash settled on the applicable installment date.

Management evaluated the embedded conversion feature to determine whether bifurcation was required as a separate derivative liability. Management first determined that the conversion feature was not within the scope of ASC 480. It then determined that the embedded derivative should be separated from the host instrument and accounted for as a derivative instrument because it met the criteria of ASC 815-15-25-1, primarily because the contract provides for delivery of an asset that puts the recipient in substantially the same position as net settlement. However, due in part to the Company’s adoption of ASC 2017-11 on April 1, 2020, which allowed management to disregard the down round provisions of the conversion feature, management determined that a scope exception to derivative accounting existed by satisfying the additional conditions necessary for equity classification specified by ASC 815-10-15-74 and ASC 815-40-25. As a result of management’s analysis, the conversion feature was not accounted for separately from the debt instrument and the Company will recognize the contingent beneficial conversion feature when, or if, such is triggered.

The original issue discount of 10% on the note was recorded as a debt discount, decreasing the note payable. This debt discount is amortized to interest expense using the effective interest rate method over the term of the loan. For the three months ended March 31, 2022 and 2021, total debt discount amortization was $1,161 and $50,928, respectively. Such amounts are included in interest expense in the accompanying consolidated statements of operations.

Debt issuance costs in the amount of $316,274 related to this indebtedness were deducted from the face value of the note. Such costs are amortized to interest expense using the effective interest rate method over the term of the loan. Total debt issuance costs amortized during the three months ended March 31, 2022 and 2021, was $1,223 and $53,690, respectively. Such amounts are included in interest expense in the accompanying consolidated statements of operations.

NOTE 9 – STOCKHOLDERS’ EQUITY

The Company’s amended and restated certificate of incorporation filed on December 14, 2017, authorizes the Company to issue 10,000,000 shares of preferred stock and 50,000,000 shares of common stock.

Amendment to 2017 Plan

On June 24, 2020, the Company amended the 2017 Equity Incentive Plan (as amended, the “2017 Plan”) to increase the maximum limitation of the number of shares of common stock with respect to one or more Stock Awards (as defined in the 2017 Plan) that may be granted to any one participant under the 2017 Plan during any calendar year from 500,000 shares to 1,000,000 shares.

On May 19, 2021, the Company’s stockholders approved, by a majority of votes cast, the Company’s proposal to increase the number of shares authorized for issuance under the 2017 Plan from 1,500,000 shares to 3,000,000 shares of common stock of the Company pursuant to the terms and conditions of the 2017 Plan. The amendment took effect upon receipt of stockholder approval.

S-8 Registration Statement

On June 21, 2021, the Company filed a Form S-8 Registration Statement relating to 3,543,114 shares of the Company’s common stock, par value $0.0001 per share, issuable to the employees, officers, directors, consultants and advisors of the Company under the Company’s 2017 Plan, One Stop Systems, Inc. 2015 Stock Option Plan, and One Stop Systems, Inc. 2011 Stock Option Plan.

Stock Options

Effective June 24, 2020, the Company entered into an employment agreement with David Raun to serve as the Company’s president and chief executive officer. Pursuant to the terms of the employment agreement, Mr. Raun is entitled to receive 412,125 restricted stock units (“RSUs”) that shall vest over three years, with one third of the RSUs vesting following the one-year anniversary of the date of grant, and the remaining RSUs vesting in four equal installments, commencing nine months after the one-year anniversary of the date of grant and every nine months thereafter until fully vested; and 412,125 Incentive Stock Options (“ISOs”) pursuant to the Company’s 2017 Plan, whereby the exercise price for the ISOs shall be no less than the fair market value of the Company’s common stock at the date of grant ($2.14).

The ISOs shall vest at the end of each of the second and fourth quarters, the price of the Company’s common stock as of the end of quarter two or quarter four, as applicable, shall be determined using the ten-day trailing volume weighted average price (“VWAP”) after reporting of quarter two and quarter four earnings, as applicable. The date of each such determination shall be referred to as a “Determination Date.” If on any Determination Date the Company’s stock price has increased from the prior Determination Date, then a portion of the ISOs shall become vested. The number of ISOs that shall become vested on a Determination Date is determined as follows: ((Price at Determination Date – Price at prior Determination Date) x 100) * 1,177.52 = Vested ISOs. If on any Determination Date the Company’s stock price is $5.50 per share, all ISOs shall immediately become vested. Mr. Raun’s ISOs are fully vested, but not exercised, based upon achievement of the specified performance objectives.

In the event that Mr. Raun’s employment agreement is terminated for a reason other than “good cause” or for “good reason,” upon Mr. Raun’s execution of an effective waiver and release of claims, unvested RSUs shall accelerate so that an additional twelve (12) months of RSUs shall vest from the termination date.

A summary of stock option activity under each of the Company’s equity incentive plans during the three month period ended March 31, 2022, is as follows:

|  | Stock Options Outstanding |

There were no options granted during the three month periods ended March 31, 2022 and 2021. The following table presents the grant date fair value of options vested and the intrinsic value of options exercised:

|  | For the Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
Grant date fair value of options vested |  | $ | 2,014,092 |  |  | $ | 1,160,847 |
Intrinsic value of options exercised |  | $ | 113,076 |  |  | $ | 1,047,002 |

As of March 31, 2022, the amount of unearned stock-based compensation estimated to be expensed from 2022 through 2025 related to unvested stock options is $6,622, net of estimated forfeitures. The weighted-average period over which the unearned stock-based compensation is expected to be recognized is 0.55 years.

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

Restricted Stock Units

RSUs may be granted at the discretion of the compensation committee of the Board of Directors under the Company’s 2017 Plan in connection with the hiring and retention of personnel and are subject to certain conditions. RSUs generally vest quarterly or semi-annually over a period of one to three years and are typically forfeited if employment is terminated before the RSUs vest. The compensation expense related to the RSUs is calculated as the fair value of the common stock on the grant date and is amortized to expense over the vesting period and is adjusted for estimated forfeitures.

The Company’s RSU activity for the three months ended March 31, 2022, is as follows:

|  | Restricted Stock Units |
|  | Number of Shares |  |  | Weighted Average Grant Date Fair Value |
Unvested on January 1, 2022 |  |  | 604,800 |  |  | $ | 4.30 |

NOTE 10 – COMMITMENTS AND CONTINGENCIES

Legal

We are subject to litigation, claims, investigations, and audits arising from time to time in the ordinary course of our business.

On September 29, 2020, the Company’s former Chief Executive Officer, Stephen D. Cooper, commenced an action against the Company entitled Stephen D. Cooper v. One Stop Systems, Inc. et al, in San Diego County Superior Court, Case No. 37-2020-00034492-CU-BC-CTL. Mr. Cooper alleged claims for (1) breach of written contract and (2) violation of California Labor Code Sections 201 and 203 in connection with the Company’s alleged failure to pay unpaid wages and an earned bonus following the Company’s termination of Mr. Cooper’s employment with the Company in February 2020. Mr. Cooper sought unspecified compensatory damages and statutory penalties.

The Company denied Mr. Cooper’s allegations. On December 8, 2020, the Company filed a cross-complaint (“Cross Complaint”) against Mr. Cooper for (1) breach of contract (in connection with a binding commitment letter and Mr. Cooper’s employment agreement); (2) intentional misrepresentation; (3) negligent misrepresentation; and (4) breach of fiduciary duty pursuant to which the Company sought compensatory damages, punitive damages, pre-judgment interest, attorneys’ fees, and the cost of suit incurred in connection with Mr. Cooper’s complaint and the Cross Complaint.

On June 28, 2021, pursuant to the parties’ agreement to resolve all of their disputes, the court entered a dismissal with prejudice of the litigation, including all claims and cross-claims. As a result, these actions have been resolved.

Guarantees and Indemnities

The Company has made certain indemnities, under which it may be required to make payments to an indemnified party, in relation to certain transactions. The Company indemnifies its directors, officers, employees, and agents to the maximum extent permitted under the laws of the State of Delaware. In connection with its facility lease, the Company has indemnified its lessor for certain claims arising from the use of the facilities. The duration of the indemnities varies, and in many cases is indefinite. These indemnities do not provide for any limitation of the maximum potential future payments the Company could be obligated to make. Historically, the Company has not been obligated to make any payments for these obligations and no liabilities have been recorded for these indemnities in the accompanying consolidated balance sheets.

Leases

The Company leases its offices, manufacturing, and warehouse facility in San Diego County under a non-cancelable operating lease. Our corporate headquarters are in a leased space comprising of approximately 29,342 square feet in Escondido, California under a lease that was modified in February 2019 and expires in August 2024. The Company also leases a 3,208 square foot facility in Salt Lake City, Utah that houses our Ion software development team which expires in June 2023. The Company is the lessee of 12,880 square feet located in Irvine, California which expires in June 2023. Bressner leases space comprised of 8,073 square feet on a month-to-month basis. All Company leases are operating leases with a weighted average remaining lease term of 32 months with a weighted average discount rate of 12.28%. For the three months ended March 31, 2022 and 2021, rent expense was $161,535 and $251,130, respectively.

Overview

One Stop Systems, Inc. (the “Company”) designs, manufactures, and markets specialized high-performance computing modules and systems, which are designed to target edge deployments. These specialized modules and systems consist of computers and storage products that incorporate the latest state-of-the art components with our embedded proprietary software. Such modules and systems allow our customers to offer high-end computing capabilities (often integrated within their equipment) to their target markets and applications. Edge computing is a form of computing that is done on site, near a particular data source or the user (rather than in the cloud), minimizing the need for data to be processed in a remote data center. The global increase in load on the cloud infrastructure and increase in artificial intelligence (“AI”) applications are the primary factors driving the growth of the edge computing market. We market our products to manufacturers of automated equipment used for media and entertainment, medical, industrial, and military applications. Our customer applications often require connection to a wide array of data sources and sensors, ultra-fast processing power, and the ability to quickly access and store large and ever-growing data sets at their physical location (rather than in the cloud). This equipment requires datacenter class performance optimized for deployment at the edge in challenging environments. Many of these edge applications have unique requirements, including special and compact form factors ruggedized for harsh conditions, which cannot be accommodated by traditional controlled air-conditioned data centers. We believe that we are uniquely positioned as a specialized provider to address the needs of this market, providing custom servers, data acquisition platforms, compute accelerators, solid-state storage arrays, system I/O expansion systems, as well as edge optimized industrial and panel PCs, tablets, and handheld compute devices. Our systems also offer industry leading capabilities that occupy less physical space and require less power consumption. We deliver this high-end technology to our customers through the sale of equipment and embedded software.

One Stop Systems, Inc. was originally incorporated as a California corporation in 1999, after initially being formed as a California limited liability company in 1998. On December 14, 2017, the Company was reincorporated as a Delaware corporation in connection with the initial public offering of its securities.

During the year ended December 31, 2015, the Company formed a wholly owned subsidiary in Germany, One Stop Systems, GmbH (“OSS GmbH”). In July 2016, the Company acquired Mission Technologies Group, Inc. (“Magma”) and its operations.

On August 31, 2018, the Company acquired Concept Development Inc. (“CDI”) located in Irvine, California. CDI specializes in the design and manufacture of custom high-performance computing systems for airborne in-flight entertainment and networking systems. CDI has been fully integrated into the core operations of OSS as of June 1, 2020.

On October 31, 2018, OSS GmbH acquired 100% of the outstanding stock of Bressner Technology GmbH, a Germany limited liability company located near Munich, Germany (“Bressner”). Bressner designs and manufactures standard and customized servers, panel PCs, and PCIe expansion systems. Bressner also provides manufacturing, test, sales, and marketing services for customers throughout Europe.

Recent Developments

The negative impact of the COVID-19 pandemic and the impact on the global economy and capital markets resulting from the geopolitical instability caused in part by the ongoing military conflict between Russia and Ukraine, have contributed to global supply chain issues and economic uncertainty, which has affected negatively our operations. For example, the Company’s revenue growth during fiscal year 2020 slowed due to the effects of COVID-19 and, although it rebounded in 2021, it has not yet fully recovered, particularly in our media and entertainment business.

Currently, we are experiencing increased pricing, longer lead-times, unavailability of product and limited supplies, protracted delivery dates, changes in minimum order quantities to secure product, and/or shortages of certain parts and supplies that are necessary components for the products and services we offer to our customers. As a result, the Company is carrying increased inventory balances to ensure availability of necessary products and to secure pricing. Additionally, products that are in the “work-in-process” stage and our inventory of finished goods have increased due to as the timing and availability of certain componentry necessary to complete our products.

These global issues are also impacting some of our customers, who are experiencing downturns or uncertainty in their own business operations and revenue, and as a result, these customers may need to decrease or delay their technology spending, requested pricing concessions or payment extensions, or seek to renegotiate their contracts.

As a result of these global issues, it has been difficult to accurately forecast our revenues or financial results, especially given the near and long-term impact of the pandemic and geopolitical issues. In addition, while the potential impact and duration of these issues on the economy and our business may be difficult to assess or predict, these world events have resulted in, and may continue to result in, significant disruption of global financial markets, and may reduce our ability to access additional capital, which could negatively affect our liquidity in the future. Our results of operations could be materially below our forecasts as well, which could adversely affect our results of operations, disappoint analysts and investors, or cause our stock price to decline.

Furthermore, a decrease in orders in a given period could negatively affect our revenues in future periods. These global issues and events may also have the effect of heightening many risks associated with our customers and supply chain. We may take further actions that alter our operations as may be required by federal, state, or local authorities from time to time, or which we determine are in our best interests. In addition, we may decide to postpone or abandon planned investments in our business in response to changes in our business, which may impact our ability to attract and retain customers and our rate of innovation, either of which could harm our business.

Management’s plans with respect to the above is to continue their efforts towards responding to the changing economic landscape, to continue to control costs, conserve cash, strengthen margins, and improve company-wide execution.

Components of Results of Operations

Revenue

The Company recognizes revenue under accounting standard ASC 606. Revenue is primarily generated from the sale of computer hardware and engineering services and to a minimal extent the sale of software, and sales of software maintenance and support contracts. 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: (1) identification of the contract with a customer; (2) identification of the performance obligations in the contract; (3) determination of the transaction price; (4) allocation of the transaction price to the performance obligations in the contract; and (5) recognition of revenue when, or as, a performance obligation is satisfied.

29

Cost of revenue

Cost of revenue primarily consists of costs of materials, costs paid to third-party contract manufacturers (which may include the costs of components), and personnel costs associated with manufacturing and support operations. Personnel costs consist of wages, bonuses, benefits, and stock-based compensation expenses. Cost of revenue also includes freight, allocated overhead costs and inventory write-offs and changes to our inventory and warranty reserves. Allocated overhead costs consist of certain facilities and utility costs. We expect cost of revenue to increase in absolute dollars with an improvement in margin, as product revenue increases.

Operating expenses

Our operating expenses consist of general and administrative, marketing and selling, and research and development expenses. Salaries and personnel-related costs, benefits, and stock-based compensation expense are the most significant components of each category of operating expenses. Operating expenses also include allocated overhead costs for facilities and utility costs.

General and Administrative - General and administrative expense consists primarily of employee compensation and related expenses for administrative functions including finance, legal, human resources, and fees for third-party professional services, as well as allocated overhead. We expect our general and administrative expense to increase in absolute dollars as we continue to invest in growing the business.

Marketing and Selling – Marketing and selling expense consists primarily of employee compensation and related expenses, sales commissions, marketing programs, travel, and entertainment expenses as well as allocated overhead. Marketing programs consist of advertising, tradeshows, events, corporate communications, and brand-building activities. We expect marketing and selling expenses to increase in absolute dollars as we expand our sales force, increase marketing resources, and further develop sales channels.

Research and Development - Research and development expense consists primarily of employee compensation and related expenses, prototype expenses, depreciation associated with assets acquired for research and development, third-party engineering, and contractor support costs, as well as allocated overhead. We expect our research and development expenses to increase in absolute dollars as we continue to invest in new and existing products.

Other Income (Expense), net

Other income consists of miscellaneous income and income received from activities outside of our core business. Other expense includes expenses from activities outside of our core business.

Provision for Income Taxes

Provision for income taxes consists of estimated income taxes due to the United States and German governments as well as state tax authorities in jurisdictions in which we conduct business, along with the change in our deferred income tax assets and liabilities.

Revenue

For the three month period ended March 31, 2022, total revenue increased $3,736,925, or 28%, as compared to the same period in 2021. OSS saw an increase in revenue of $1,980,071, or 23%, as compared to the prior year in 2021. The majority of this increase is attributable to an increase in shipments of product to our media and entertainment customer. Bressner experienced improved revenue of $1,756,854, or 37.3%, as compared to the prior year in 2021. This increase is mainly due to a general economic improvement in Europe attributable to the diminishing impact of the COVID-19 pandemic in the current business environment.

Cost of revenue and gross profit

Cost of revenue increased $3,029,054, or 34.1%, for the three month period ended March 31, 2022, as compared to the prior year in 2021. OSS saw an increase in cost of revenue of $1,460,349, or 27.3%, as compared to the prior year in 2021 The increase in cost of revenue is mainly attributable to our improved sales to our media and entertainment customer. Bressner’s cost of revenue increased $1,568,705, or 44.3%, as compared to the prior year in 2021, which increase is primarily attributable to higher sales and changes in product mix.

The overall gross margin percentage decreased from 33.3% for the three month period March 31, 2021, to 30.1% for the same period ended March 31, 2022, a decrease of 3.2 percentage points. OSS’ gross margin percentage for the three months ended March 31, 2022, was 35.7%, a decrease of 2.2 percentage points as compared to the prior year period in 2021 of 37.9%, which the decrease was primarily attributable to a higher concentration of the sales of our media and entertainment product. Bressner contributed gross margin at a rate of 21% as compared to the same prior year period in 2021 of 24.9%, a decrease of 3.9 percentage points which was primarily attributable to an increase in material and transportation costs.

Operating expenses

General and administrative expense

General and administrative expense decreased $382,930, or 17.8%, for the three month period ended March 31, 2022, as compared to the same prior year period in 2021. OSS experienced a decrease of $286,967, or 17.6% and Bressner had a decrease $95,963, or 18.1%. The decrease in general and administrative expense is primarily attributable to a reduction in stock compensation expense, which was higher in the prior year due to the acceleration of performance based vesting and legal costs. We have reinstated certain employee benefits, implemented pay increases and reestablished certain services that were suspended during the strict policies implemented during the height of the pandemic. Overall, total general and administrative expense decreased as a percentage of revenue to 10.4% during the three month period ended March 31, 2022, as compared to 16.2% during the same period in 2021.

32

Selling and marketing expense

Selling and marketing expense increased $303,819, or 26%, during the three month period ended March 31, 2022, as compared to the same prior year period in 2021. OSS had an increase of $260,224, or 29.2%, which was mainly attributable to normalized business activities which include trade shows, business travel, and increased marketing activities. Bressner had an increase of $43,595, or 15.7%, due to new marketing personnel and sales collateral materials. Generally, both OSS and Bressner experienced additional marketing costs as markets are beginning to re-open now that certain restrictions have been lifted that were previously imposed during the height of the COVID-19 pandemic. Overall, total marketing and selling expense decreased as a percentage of revenue to 8.6% during the three month period ended March 31, 2022, as compared to 8.8% during the same period in 2021.

Research and development expense

Research and development expense increased $411,882, or 49.5%, during the three month period ended March 31, 2022, as compared to the same prior year period in 2021. OSS saw an increase of $403,574 or 55%. This increase was largely driven by the deployment of more engineering resources on internal development projects rather than on customer billable projects for which such costs would have been charged to cost of revenue rather than being charged to research and development expense. Bressner had a modest increase of $8,308, or 8.4%. Overall, total research and development expense as a percentage of revenue increased as a percentage of revenue to 7.3% during the three month period ended March 31, 2022, as compared to 6.2% during the same period in 2021.

Interest income

Interest income increased $45,705 for the three month period ended March 31, 2022, as compared to the same prior year period in 2021. The increase is attributable to interest on marketable securities that were purchased in April 2021.

Interest expense

Interest expense decreased $91,267 for the three month period ended March 31, 2022, as compared to the same period in 2021. On April 24, 2020, the Company borrowed $3,000,000 through a senior secured convertible debt offering issued with a 10% original issue discount and incurred legal costs associated with this debt offering. Interest and related transaction costs are amortized using the effective interest method for which the periodic amortization costs decreases over the time. The notes issued in the debt offering were scheduled to mature on April 1, 2022; however, on March 31, 2022, these notes converted into shares of common stock of the Company.

Other income (expense), net

Other income (expense) for the three month period ended March 31, 2022, resulted in net other income of $102,121, as compared to net other expense of $28,629 in the same prior year period in 2021, for a net increase of $130,750. The most significant contribution to this increase is the sale of the URL for Magma.com, off-set by foreign currency losses.

Provision (benefit) for income taxes

We have recorded an income tax provision of $165,308 and $60,522, respectively, for the three month period ended March 31, 2022 and 2021, respectively. The effective tax rate for the period ended March 31, 2022 and 2021, differs from the statutory rate mainly due to permanent non-deductible goodwill amortization for Bressner Technology GmbH, deductions related to expenses of OSS stock options, as well as projecting federal, foreign and state tax liabilities for the year. The annual expect tax rate for 2022 is anticipated to be approximately 20.66%.

33

Liquidity and capital resources

On March 3, 2021, we sold and issued 1,497,006 shares of Company common stock to an accredited investor pursuant to a Securities Purchase Agreement through a registered direct offering, resulting in net proceeds of $9,188,673 to us.

Historically, our primary sources of liquidity have been provided by public and private offerings of our securities and revenues generated from our business operations. As of March 31, 2022, we had total cash and cash equivalents of $2,219,800, with short-term investments of $13,540,410, and total working capital of $31,447,290. Cash and cash equivalents held by Bressner totaled US$979,990 on March 31, 2022. Bressner’s debt covenants do not permit the use of those funds by its parent company.

During the year ended December 31, 2021, we had income from operations of $1,747,027, with cash generated by operating activities of $5,622,596.

Our sources of liquidity and cash flows are used to fund ongoing operations, fund research and development projects for new products and technologies, and provide ongoing support services for our customers. Over the next year, we anticipate that we will use our liquidity and cash flows from our operations to fund our growth. In addition, as part of our business strategy, we occasionally evaluate potential acquisitions of businesses and products and technologies. Accordingly, a portion of our available cash may be used at any time for the acquisition of complementary products or businesses. Such potential transactions may require substantial capital resources, which may require us to seek additional debt or equity financing. We cannot assure you that we will be able to successfully identify suitable acquisition candidates, complete acquisitions, successfully integrate acquired businesses into our current operations, or expand into new markets. Furthermore, we cannot provide assurances that additional financing will be available to us in any required time frame and on commercially reasonable terms, if at all.

Our revenue growth during 2020 slowed due to the effects of COVID-19, and, although it rebounded somewhat in 2021, it has not yet fully recovered, particularly in our media and entertainment business. However, through a reduction in force and strict cost containment, we have been able to mitigate the effects, to some degree, of the reduced revenue. For a further description and risk factors associated with COVID-19, please see Part 1A of our Annual Report filed on March 24, 2022.

Management’s plans are to continue its efforts towards responding to the changing economic landscape by continuing to control hiring and costs, conserve cash, strengthen margins, and improve company-wide execution.

While management expects these actions to result in prospective cost containment, and our results of operations for the year ended December 31, 2021, and the three month period ended March 31, 2022, improved partially as a result of such actions, management is also committed to conserving cash and securing debt and/or equity financing, as required, for liquidity to meet our cash requirements through at least a period of the next twelve months. Management believes potential sources of liquidity include at least the following:

| ▪ | In May 2019, we filed a registration statement on Form S-3 (Registration No. 333-231513) with the SEC, which became effective on June 19, 2019, and allows us to offer and sell up to an aggregate of $100,000,000 of our common stock, preferred stock, debt securities, warrants to purchase our common stock, preferred stock or debt securities, subscription rights to purchase our common stock, preferred stock or debt securities and/or units consisting of some or all of these securities, in any combination, together or separately, in one or more offerings, in amounts, at prices and on the terms that we will determine at the time of the offering and which will be set forth in a prospectus supplement and any related free writing prospectus. The registration statement will automatically terminate effective June 19, 2022, after which date, we will no longer be able to use the registration statement.

As a result of management’s implementation of our cost reduction plans, our potential sources of liquidity and management’s most recent cash flow forecasts, management believes that we have sufficient liquidity to satisfy our anticipated working capital requirements for our ongoing operations and obligations for at least the next twelve months. However, there can be no assurance that management’s cost reduction efforts will be effective or the forecasted cash flows will be achieved. Furthermore, we will continue to evaluate our capital expenditure needs based upon factors including but not limited to, our sales from operations, growth rate, the timing and extent of

34

spending to support development efforts, the expansion of our sales and marketing efforts, the timing of new product introductions, and the continuing market acceptance of our products and services.

If cash generated from operations is insufficient to satisfy our capital requirements, we may open a revolving line of credit with a bank, may have to sell additional equity or debt securities, or may obtain expanded credit facilities to fund our operating expenses, pay our obligations, diversify our geographical reach, and grow the Company. In the event such financing is needed in the future, there can be no assurance that such financing will be available to us, or, if available, that it will be in amounts and on terms acceptable to us. If we cannot raise additional funds when we need or wants them, our operations and prospects could be negatively affected. However, if cash flows from operations become insufficient to continue operations at the current level, and if no additional financing were obtained, then management would consider restructuring the Company in a way to preserve its business while maintaining expenses within operating cash flows.

The following table summarizes our cash flows for the three month periods ended March 31, 2022 and 2021:

|  | For the Three Months Ended March 31, |
Cash flows: |  | 2022 |  |  | 2021 |
Net cash (used in) provided by operating activities |  | $ | (5,018,398 | ) |  | $ | 4,291,066 |
Net cash provided by (used in) investing activities |  | $ | 1,028,504 |  |  | $ | (121,759 | )
Net cash provided by financing activities |  | $ | 1,131,345 |  |  | $ | 9,173,593 |

Operating Activities

During the three month period ended March 31, 2022, we used $5,018,398 in cash from operating activities, a difference of $9,309,464 when compared to the cash provided by operating activities of $4,291,066 during the three month period in year 2021. This significant decrease in operating cash flow is mainly attributable to improved earnings resulting from increased sales, offset by a significant increase in working capital requirements for accounts receivable and inventories.

The change is cash used in operating activities during the three month period ended March 31, 2022, as compared to the same period in 2021, is primarily a result of the improvement in profitability from net income of $41,198 in the prior year period to net income of $579,234 in the current year, an improvement of $538,036. Net negative adjustments for non-cash items of $(324,818) were comprised of $227,691 of favorable non-cash items, offset by $552,509 of negative non-cash items that did not generate operating cash flow. Additionally, there was an increase in the use of operating cash flow for working capital items of $9,522,682.

Net working capital requirements for the three month period ended March 31, 2022, were $6,245,595, as compared to the prior year period sources of working capital of $3,277,087, an increase in the use of working capital of $9,522,682. The source of working capital of $559,024 was attributable to changes in accounts payable for the comparable period. This source was offset by uses of working capital of $10,081,706 being applied to changes in accounts receivables, inventory levels, prepaid and other current assets, accrued expenses, and other liabilities.

Our ability to generate cash from operations in future periods will depend in large part on our profitability, the rate and timing of collections of our accounts receivable, our inventory turns and our ability to manage other areas of working capital, including accounts payable and accrued expenses

Investing Activities

During the three month period ended March 31, 2022, the Company generated cash of $1,028,504 in investing activities, as compared to $121,759 used during the prior year period in 2021, an improvement of $1,150,263. The source of investing funds was attributable to the redemption of short-term investments and the sale of the Magma.com URL. Additionally, the Company continues to enhance the capabilities of its ERP system, and purchase test equipment for the engineering department. We do not anticipate any significant investments not normally anticipated in the original course of business.

35

Financing Activities

Given the current economic, financial, and geopolitical instability, the Company believes it is imperative to maintain opportunities for additional financial resources to ensure financial stability during trying economic times. During the three month period ended March 31, 2022, the Company generated $1,131,345 in cash from borrowing activities for Bressner for working capital to finance inventory purchases, as compared to the cash provided by financing activities of $9,173,593, during the same three month period year in 2021. The main differences between the comparative periods are new borrowings from our German subsidiary, Bressner for inventories, and the proceeds received in the prior year from a $10,000,000 registered direct offering that was completed in March 2021.

Known trends or uncertainties

Although we have not seen any significant reduction in revenues to date due to consolidations, we have seen some consolidation in our industry during economic downturns. These consolidations have not had a negative effect on our total sales; however, should consolidations and downsizing in the industry continue to occur, those events could adversely impact our revenues and earnings going forward.

As discussed in this Quarterly Report on Form 10-Q, the world has been affected due to the COVID-19 pandemic. Until the pandemic has passed, there remains uncertainty as to the effect of COVID-19 on our business in both the short and long-term.

We believe that the need for improved productivity in the research and development activities directed toward developing new products and/or software will continue to result in increasing adoption of high-performance computers and interconnect technologies such as those we produce. New product and/or software developments in the specialized compute business segment could result in increased revenues and earnings if they are accepted by our markets; however, there can be no assurances that new products and/or software will result in significant improvements to revenues or earnings. For competitive reasons, we do not disclose all of our new product development activities.

Also, the potential for growth in new markets is uncertain. We will continue to explore these opportunities until such time as we either generate sales or determine that resources would be more efficiently used elsewhere.

Inflation

We have not been affected materially by inflation during the periods presented, but we may experience some effect in the near future due to increased product pricing due to semiconductor product shortages, increased transportation costs due to increases in the cost of energy and general price increases due to inflation in the economy.

Off balance sheet arrangements

We do not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any obligation arising out of a material variable interest in an unconsolidated entity.

We do not have any majority-owned subsidiaries that are not consolidated in the financial statements. Additionally, we do not have an interest in, or relationships with, any special purpose entities.

Stockholder transactions

See Note 11 to the accompanying financial statements for a discussion regarding our stockholder transactions for the relevant periods.

Critical accounting policies and estimates

In preparing our consolidated financial statements in conformity with U.S. generally accepted accounting principles, management must make a variety of decisions which impact the reported amounts and the related disclosures. These decisions include the selection of the appropriate accounting principles to be applied and the assumptions on which to base accounting estimates. In making these decisions, management applies its judgment based on its understanding and analysis of the relevant circumstances and our historical experience.

Our accounting policies and estimates that are most critical to the presentation of our results of operations and financial condition, and which require the greatest use of judgments and estimates by management, are designated as our critical accounting policies. See further discussion of our critical accounting policies under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our Annual Report on Form 10-K for year ended December 31, 2021. We periodically re-evaluate and adjust our critical accounting policies as circumstances change. There were no significant changes to our critical accounting policies during the three month period ended March 31, 2022, except for adoption of ASU No. 2016-02, Leases (“ASU 2016-02”).

Leases

On January 1, 2022, the Company adopted ASC 842 using the Transition method. The reported results for the three month period ended March 31, 2022, reflect the application of the guidance of ASC 842 while the reported results for the three month period ended March 31, 2021, was prepared under the guidance of ASC 840.

Per the Company’s consolidated financial statements Note 2- Significant Accounting Policies, we have adopted “Lease accounting” as required by FASB ASC 842. See Note 2 to the accompanying financial statements for further details.

Recently implemented accounting pronouncements

Effective January 1, 2022, the Company implemented ASU No. 2016-02, Leases (“ASU 2016-02”). Under ASU 2016-02, the Company recognized for all leases a lease liability, which is our 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. The Company elected to use the transition method and reflected the cumulative effect of adoption as an adjustment to beginning retained earnings.

Interest rate risk

Our exposure to interest rate risk is primarily associated with borrowing on revolving lines of credit denominated in both U.S. dollars and Euros. We are exposed to the impact of interest rate changes primarily through our borrowing activities for our variable rate borrowings.

Concentration of credit risk

Financial instruments that potentially expose us to concentrations of credit risk consist principally of cash, cash equivalents, short-term investments and accounts receivable. We place our cash and cash equivalents with financial institutions with high credit quality. On March 31, 2022 and December 31, 2021, we had $2,219,800 and $5,101,174, respectively, of cash and cash equivalents on deposit or invested with our financial and lending institutions. We provide credit to our customers in the normal course of business. We perform ongoing credit evaluations of our customers’ financial condition and limit the amount of credit extended when deemed necessary.

37

Foreign currency risk

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, and acquired Bressner in October 2018. 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 translated 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 in the consolidated statement of comprehensive income.

Derivative Financial Instruments

We employ derivatives on a periodic basis to manage certain 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 may enter into foreign exchange contracts to provide currency at a fixed rate.

Non-GAAP Financial Measures

Adjusted EBITDA

We believe that the use of adjusted earnings before interest, taxes, depreciation and amortization, or adjusted EBITDA, is helpful for an investor to assess the performance of the Company. The Company defines adjusted EBITDA as income (loss) before interest, taxes, depreciation, amortization, acquisition expenses, impairment of long-lived assets, financing costs, fair value adjustments from purchase accounting, stock-based compensation expense and expenses related to discontinued operations.

Adjusted EBITDA is not a measurement of financial performance under generally accepted accounting principles in the United States, or GAAP. Because of varying available valuation methodologies, subjective assumptions and the variety of equity instruments that can impact a company’s non-cash operating expenses, we believe that providing a non-GAAP financial measure that excludes non-cash and non-recurring expenses allows for meaningful comparisons between our core business operating results and those of other companies, as well as providing us with an important tool for financial and operational decision making and for evaluating our own core business operating results over different periods of time.

38

Our adjusted EBITDA measure may not provide information that is directly comparable to that provided by other companies in our industry, as other companies in our industry may calculate non-GAAP financial results differently, particularly related to non-recurring, unusual items. Our adjusted EBITDA is not a measurement of financial performance under GAAP and should not be considered as an alternative to operating income or as an indication of operating performance or any other measure of performance derived in accordance with GAAP. We do not consider adjusted EBITDA to be a substitute for, or superior to, the information provided by GAAP financial results.

| For the Three Months Ended March 31, |
| 2022 |  |  | 2021 |
Net income | $ | 579,234 |  |  | $ | 41,198 |
Depreciation and amortization |  | 269,791 |  |  |  | 380,778 |
Stock-based compensation expense |  | 382,828 |  |  |  | 438,394 |

Adjusted EBITDA | $ | 1,404,871 |  |  | $ | 1,065,574 |

Adjusted EPS

Adjusted EPS excludes the impact of certain items, and therefore, has not been calculated in accordance with GAAP. We believe that exclusion of certain selected items assists in providing a more complete understanding of our underlying results and trends and allows for comparability with our peer company index and industry. We use this measure along with the corresponding GAAP financial measures to manage our business and to evaluate our performance compared to prior periods and the marketplace. The Company defines non-GAAP income (loss) as income or (loss) before amortization, stock-based compensation, expenses related to discontinued operations, impairment of long-lived assets and non-recurring acquisition costs. Adjusted EPS expresses adjusted income (loss) on a per share basis using weighted average diluted shares outstanding.

Adjusted EPS is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. These non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies. We expect to continue to incur expenses similar to the adjusted income from continuing operations and adjusted EPS financial adjustments described above, and investors should not infer from our presentation of these non-GAAP financial measures that these costs are unusual, infrequent or non-recurring.

The following table reconciles non-GAAP net income (loss) and basic and diluted earnings per share:

|  | For the Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
Net income |  | $ | 579,234 |  |  | $ | 41,198 |

Free Cash Flow

Free cash flow, a non-GAAP measure for reporting cash flow, is defined as cash provided by or used in operating activities, less capital expenditures for property and equipment, which includes capitalized software development costs for the implementation of the Company’s ERP system. We believe free cash flow provides investors with an important perspective on cash available for investments and acquisitions after making capital investments required to support ongoing business operations and long-term value creation. We believe that trends in our free cash flow can be valuable indicators of our operating performance and liquidity.

Free cash flow is a non-GAAP financial measure and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. This non-GAAP financial measure may not be computed in the same manner as similarly titled measures used by other companies.

We expect to continue to incur expenditures similar to the free cash flow adjustments described above, and investors should not infer from our presentation of this non-GAAP financial measure that these expenditures reflect all of our obligations which require cash. The following table reconciles cash provided by or used in operating activities, the most directly comparable GAAP financial measure, to free cash flow:

|  | For the Three Months Ended March 31, |
Cash flow: |  | 2022 |  |  | 2021 |
Net cash (used in) provided by operating activities |  | $ | (5,018,398 | ) |  | $ | 4,291,066 |
Capital expenditures |  |  | (85,841 | ) |  |  | (121,759 | )
Free cash flow |  | $ | (5,104,239 | ) |  | $ | 4,169,307 |

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Not Applicable.

Item 4. Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic and current reports that we file with the SEC is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Limitation on Effectiveness of Controls

The design of any control system is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals. The inherent limitations in any control system include the realities that judgments related to decision-making can be faulty, and that reduced effectiveness in controls can occur because of simple errors or mistakes. Due to the inherent limitations in a cost-effective control system, misstatements due to error may occur and may not be detected.

Evaluation of Disclosure Controls and Procedures

Management is required to evaluate our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Disclosure controls and procedures are controls and other procedures designed to provide reasonable assurance that information required to be disclosed in our reports filed under the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include controls and procedures designed to provide reasonable assurance that such information 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. Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were effective at a reasonable assurance level as of the end of the period covered by this report.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2022, which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and 15d-15 under the Exchange Act, that have materially affected or are reasonably likely to materially affect our internal control over financial reporting.
