FORWARD-LOOKING STATEMENTS

This quarterly report on Form 10-Q ("Quarterly Report"), contains forward-looking statements that involve substantial risks and uncertainties. The forward-looking statements are contained principally in the section entitled "Management's Discussion and Analysis of Financial Condition and Results of Operations." All statements, other than statements of historical facts, contained in this Quarterly Report, including statements regarding our strategy, future operations, future financial position, projected costs, prospects, plans and objectives of management, are forward-looking statements. Words such as, but not limited to, "anticipate," "aim," "believe," "contemplate," "continue," "could," "design," "estimate," "expect," "intend," "may," "might," "plan," "possible," "potential," "predict," "project," "seek," "should," "suggest," "strategy," "target," "will," "would," and similar expressions or phrases, or the negative of those expressions or phrases, are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words.

These forward-looking statements include, among other things, statements about:

•

our ability to adjust to economic uncertainty and capital markets disruption, which has been significantly impacted by geopolitical instability, and could harm our financial condition and results of operations;

•

our ability to remediate issues with volatile or recessionary conditions in the United States or abroad which could adversely affect our business and/or our access to capital markets in a material manner;

2

•

adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect our current and projected business operations and our financial condition and results of operations;

•

cybersecurity incidents or data breaches that could disrupt operations or compromise proprietary information;

•

changes in current legislation, regulations, trade policies and tariffs, federal budget levels and priorities and the potential that any of the foregoing disrupts our operations and delays contract awards;

•

our ability to file Annual and Quarterly Reports on a timely basis;

•

our ability to raise additional capital to fund our operations if and as needed;

•

our ability to achieve and sustain profitability;

•

our estimates regarding our future performance including, without limitation, any estimates of potential future revenues;

•

estimates regarding market size;

•

our estimates regarding expenses, revenues, financial performance, and capital requirements, including the length of time our capital resources will sustain our operations;

•

our dependence on third parties for the supply and manufacture of our products;

•

our ability to expand our organization to accommodate potential growth; and

•

our ability to retain and attract key personnel.

Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report, we caution you that these statements are based on our projections of the future that are subject to known and unknown risks and uncertainties and other factors that may cause our actual results, level of activity, performance or achievements expressed or implied by these forward-looking statements, to differ. We may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. All forward-looking statements are qualified in their entirety by this cautionary statement. Forward-looking statements should be regarded solely as our current plans, estimates and beliefs. You should read this Quarterly Report and the documents that we have filed as exhibits to this Quarterly Report and incorporated by reference herein completely and with the understanding that our actual results may be materially different from the plans, intentions and expectations disclosed in the forward-looking statements we make. Moreover, we operate in a very competitive and rapidly changing environment and new risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. The forward-looking statements contained in this Quarterly Report are made as of the date of this Quarterly Report, and we do not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law.

PART I - FINANC IAL INFORMATION

Item 1. Financi al Statements.

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 consolidated financial statements in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC"). Therefore, such consolidated 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, management 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.

This Quarterly Report should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2025, included in our Annual Report on Form 10-K, filed with the SEC on March 18, 2026.

The results of operations for the three month period ended March 31, 2026, are not necessarily indicative of the results to be expected for the fiscal year ending December 31, 2026.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

For the Three Month Periods Ended March 31, 2026 and 2025

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 rugged high-performance compute ("HPC"), high speed switch fabrics, and storage systems, which are designed to target edge applications for artificial intelligence ("AI") / machine learning ("ML"), sensor processing, sensor fusion, and autonomy. The Company markets its products to manufacturers of equipment and platforms used for autonomous vehicles, medical, industrial, aerospace, and defense applications, with special focus on platforms that move, such as planes, unmanned aerial vehicles (UAVs), trucks, ships, submarines, and mobile datacenters or command posts where sensor processing, sensor fusion, AI, and ML are integrated to support such applications.

During the year ended December 31, 2015, the Company formed a wholly owned subsidiary in Germany, One Stop Systems, GmbH ("OSS GmbH"). On October 31, 2018, OSS GmbH acquired 100 % of the outstanding stock of Bressner Technology GmbH, a limited liability company registered under the laws of Germany and located near Munich, Germany ("Bressner"). On December 30, 2025, the Company entered into and completed a Shares Purchase Agreement with Hiper Euro GmbH, pursuant to which the Company sold 100 % of the issued and outstanding equity interests of One Stop Systems, GmbH ("OSS GmbH"), the Company's German subsidiary and the sole owner of Bressner. The transaction represents a strategic shift in the Company's operations, as the Company exited its European distribution and integration business and is now focused on its core high-performance edge computing solutions.

Following the transaction, the Company has continued to focus on the development and sale of proprietary and differentiated edge computing solutions and has enhanced its efforts to penetrate the military and defense sectors.

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").

Reclassifications

Certain prior year amounts have been reclassified to conform with the current year presentation. All operations, assets, and liabilities of the Bressner business, which was divested on December 30, 2025, have been classified as discontinued operations in all periods presented. Unless otherwise noted, amounts and disclosures in these Notes to Unaudited Consolidated Financial Statements pertain to the Company's continuing operations. See Note 13, Discontinued Operations, for further details on Discontinued Operations.

Principles of Consolidation

The accompanying unaudited consolidated financial statements include the accounts of OSS and its wholly owned subsidiaries. The accounts of OSS GmbH, which include Bressner, have been classified as discontinued operations. Intercompany balances and transactions have been eliminated in consolidation.

NOTE 2 - SIGNIFICANT ACCOUNTING POLICIES

12

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, 2025.

Use of Estimates

The preparation of 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 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 credit losses and sales reserves, income tax valuations, stock-based compensation, 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.

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 that has not been properly reflected in the consolidated financial statements. 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 .

Recently Issued Accounting Pronouncements

Adopted

On December 14, 2023, the FASB issued ASU 2023-09, "Improvement to Income Tax Disclosure (Topic 740)" which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. Under the new guidance, entities must consistently categorize and provide greater disaggregation of information in the rate reconciliation. The Company must also further disaggregate income taxes paid. The objective of these disclosure requirements is for an entity, particularly an entity operating in multiple jurisdictions, to disclose sufficient information to enable users of financial statements to understand the nature and magnitude of factors contributing to the difference between the effective tax rate and the statutory tax rate. The standard is intended to benefit investors by providing more detailed income tax disclosures that would be useful in making capital allocation decisions. This guidance applies to annual periods beginning after December 15, 2024. Adoption of this guidance did not have any material impact to our results of operations or consolidated financial statements.

Issued

On November 4, 2024, the FASB issued ASU 2024-03 "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" which requires disaggregated disclosure of certain income statement expenses.

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. When applicable, we record accruals for contingencies when it is probable that a liability will be incurred, and the amount of loss can be reasonably estimated. While the outcome of lawsuits and other proceedings against us cannot be predicted with certainty, in our opinion, individually or in the aggregate, no such lawsuits are expected to have a material effect on our consolidated financial position or results of operations.

In the opinion of management, after consultation with legal counsel, the ultimate disposition of any such matters as of March 31, 2026, is not expected to have a materially adverse effect on the consolidated financial position or results of operations of the Company.

18

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.

NOTE 12 - SEGMENT AND GEOGRAPHIC INFORMATION

The Company's continuing operations comprise a single reportable segment. Operating segments are identified based on the manner in which the Chief Operating Decision Maker ("CODM") evaluates financial performance and allocates resources.

The Company's Chief Executive Officer has been identified as the CODM. The CODM reviews financial information for purposes of assessing performance and making decisions regarding resource allocation. The CODM evaluates performance using gross profit and operating profit.

Although the Company generates revenue from multiple products and serves customers across various geographical regions, its products are designed and manufactured using similar processes and supported by centralized functions, including sales, marketing, finance, and human resources. Additionally, the Company's long-lived assets and capital expenditures related to continuing operations are deployed and managed on a consolidated basis.

The Company, through its single reportable segment, designs, manufactures, and markets specialized enterprise class high-performance compute, high speed switch fabrics, and storage hardware and software to target edge applications.

Segment details for the Company's single reportable segment are the same as those for the Company's continuing operations, as reported in the consolidated financial statements.

Revenue from customers with non-U.S. billing addresses represented approximate ly 10 % and 14 % of th e Company's revenue during the three month periods ended March 31, 2026 and 2025, respectively.

As of March 31, 2026, substantially all the Company's long-lived assets are in the United States of America.

NOTE 13 - DISCONTINUED OPERATIONS

Divestiture

On December 30, 2025, the Company entered into and completed a Shares Purchase Agreement (the "SPA") with Hiper Euro GmbH (the "Buyer"), pursuant to which the Buyer acquired 100 % of the issued and outstanding equity interests of One Stop Systems, GmbH ("OSS GmbH"), the Company's German subsidiary and the sole owner of Bressner Technology GmbH ("Bressner") (the "Transaction"). These entities represented the entirety of the Company's former European distribution and integration operations. The Transaction represent a strategic shift in the Company's operations, as the Company exited its European distribution and integration business and is now focused on its core high-performance edge computing solutions. As a result, OSS GmbH met the criteria for classification as discontinued operations as of the date of divestiture, and the historical results of OSS GmbH and Bressner have been classified as discontinued operations in the Company's consolidated financial statements. The Company does not have any significant continuing involvement in the operations of OSS GmbH or Bressner following the divestiture.

Pursuant to the SPA, the Company sold OSS GmbH for a base purchase price of $ 22,000,000 , subject to customary post-closing adjustments for net working capital, cash, indebtedness, and transaction expenses. At closing, the Company received total estimated purchase consideration of $ 22,417,422 based on preliminary working capital and other closing estimates. Post-closing adjustments for final working capital, cash, indebtedness, and transaction-related items resulted in a reduction to the purchase price of $ 157,274 . As a result of these adjustments, total purchase consideration was $ 22,260,148 . The adjustment to the purchase price was recorded during the three months ended March 31, 2026 as a reduction to the gain on sale and is reflected within discontinued operations in the consolidated statements of operations.

21

Financial Results of Discontinued Operations

For the period ended March 31, 2026, loss from discontinued operations, net of tax on the consolidated statements of operations is comprised of the post-transaction adjustments to the purchase consideration. For the period ended March 31, 2025, income from discontinued operations, net of tax on the consolidated statements of operations reflects Bressner's financial results for the period.

Overview

The Company designs, manufactures, and markets specialized enterprise class high-performance compute, high speed switch fabrics, and storage hardware and software, which are designed to target edge applications for AI/ML, sensor processing, sensor fusion, and autonomy. Edge computing is a form of computing that is done on platform or on site, connected with the data source or the user, rather than in the cloud, minimizing the need for data to be processed remotely. This growing trend increases computing performance and security, as the data does not have to travel to distant datacenter locations. Edge computing is most recognizable in applications such as sensor processing, sensor fusion, autonomy, and AI/ML. To meet the demands at the edge, we offer specialized products and system solutions that consist of computers, switch fabrics, and storage products that incorporate the latest state-of-the art components with embedded proprietary software. Such products and systems allow us to offer high-end solutions to be integrated into edge platforms in our target markets.

The global increase in load on cloud infrastructure and increase in 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 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 datacenters.

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, and system I/O expansion systems. 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.

Components of Results of Operations

Revenue

The Company's revenues are recognized in accordance with ASC 606, Revenue from Contracts with Customers. Revenue is primarily generated from the sale of computer hardware and engineering services. The Company's performance obligations are satisfied over time as work is performed or at a point in time. Revenues on certain fixed-price contracts where we provide engineering services, prototypes, and completed products are recognized over time as the Company progresses toward fulfilling its performance obligations. The majority of the Company's revenue is recognized at that point in time when products ship and control is deemed to be 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.

23

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.

Operating expenses

Our operating expenses consist of general and administrative, sales and marketing, 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 certain shared expenses which are allocated to general and administrative expense. 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 for marketing and sales functions, sales commissions, marketing programs, travel, and entertainment expenses, as well as certain shared expenses which are allocated to marketing and selling expense. 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 for research and development functions, certain prototype expenses, depreciation associated with assets acquired for research and development, third-party engineering and contractor support costs, as well as certain shared expenses which are allocated to research and development expense. We expect variability in our research and development expenses due to the timing of new product development and introductions.

Other Income (Expense), net

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

Provision for Income Taxes

Provision for income taxes consists of estimated income taxes due to the United States, 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.

(Loss) income from discontinued operations

Income from discontinued operations consists of income from our Bressner Technologies subsidiary, which was sold on December 30, 2025. Income from discontinued operations also includes the gain recognized on the sale, as well as post-closing adjustments for net working capital, cash, and indebtedness.

Comparison of the Three Month Periods Ended March 31, 2026 and 2025 from Continuing Operations:

Revenue

For the three months ended March 31, 2026, our total revenue increased $2,862,800, or 55%, as compared to the same period in 2025. This increase was driven by higher volume of production and development across multiple customers, including: 1) higher sales to a defense prime customer of data storage products to support the P-8A Poseidon reconnaissance aircraft; 2) higher sales to a medical imaging OEM of liquid-cooled server products to support a breast cancer screening application; and 3) sales to a defense prime customer related to the design, development, and delivery of prototype compute systems for an enhanced vision system for combat vehicles.

Gross Profit and Gross Margin

Gross profit increased $1,798,349, or 75.9%, for the three months ended March 31, 2026 as compared to the same period in 2025. Gross margin percentage was 51.6% for the three months ended March 31, 2026, as compared to 45.5% for the same period in 2025. The improvement in gross margin was primarily driven by: 1) engineering efficiencies realized on certain of our customer-funded development programs; and 2) more favorable manufacturing absorption due to higher production volume.

Operating expenses

General and administrative expense

26

General and administrative expense increased $536,362, or 28.1%, for the three months ended March 31, 2026, as compared to the same period in 2025. This increase was primarily attributable to higher employee incentive compensation expense and to higher fees paid for professional services. General and administrative expense decreased as a percentage of revenue to 30.3% for the three months ended March 31, 2026, as compared to 36.7% for the same period in 2025.

Marketing and selling expense

Marketing and selling expense decreased $29,914, or 1.9%, for the three months ended March 31, 2026, as compared to the same period in 2025. This decrease was primarily attributable to lower expenses related to demonstration materials. Marketing and selling expense decreased as a percentage of revenue to 19.5% for the three months ended March 31, 2026, as compared to 30.9% for the same period in 2025.

Research and development expense

Research and development expense decreased $388,103, or 32.2%, for the three months ended March 31, 2026, as compared to the same period in 2025. This decrease was primarily attributable to the deployment of engineering labor onto customer-funded development programs in 2026 and the non-recurrence of certain targeted investments in internal new product development, as well as engineering headcount reductions. Research and development expense decreased as a percentage of revenue to 10.1% for the three months ended March 31, 2026, as compared to 23.1% for the same period in 2025.

Interest income

Interest income increased $223,072 for the three months ended March 31, 2026, as compared to the same period in 2025. The increase is primarily attributable to higher investment and cash balances as a result of: 1) the sale of Bressner completed on December 30, 2025; 2) the proceeds from the registered direct offering of common stock completed on October 1, 2025; and 3) cash generated from operations in the three months ended March 31, 2026.

Other income (expense), net

Other income (expense), for the three months ended March 31, 2026, resulted in net other income of $12,461, as compared to net other expense of $1,267 in the same period in 2025, for an increase in net other income of $13,728. This increase was primarily attributable to changes in foreign currency gains and losses, as well as higher rebates.

(Loss) income from discontinued operations, net of income taxes

(Loss) income from discontinued operations, net of income taxes resulted in a loss of $157,274 in the three months ended March 31, 2026, compared to income of $261,759 for the same period in 2025. The loss in the current year period was due to post-transaction adjustments to the gain on sale of the Bressner business for final net working capital balances. Income in the prior year period resulted from the operations of the Bressner business, which was divested on December 30, 2025.

Liquidity and Capital Resources

Historically, our primary sources of liquidity have been provided by public and private offerings of our securities and revenues generated from our business operations. In December 2025, we also received cash from the sale of our Bressner subsidiary. As of March 31, 2026, we had total cash, cash equivalents, and restricted cash of $26,544,041; short-term investments of $10,033,654; and total working capital of $44,740,475.

During the three month period ended March 31, 2026, we had a loss from operations related to continuing operations of $671,187, with cash provided by continuing operating activities of $4,041,908.

During the three month period ended March 31, 2025, we had a loss from operations related to continuing operations of $2,351,191, with cash used in continuing operating activities of $1,505,184.

27

During the year ended December 31, 2025, we had a loss from operations related to continuing operations of $3,379,112, with cash used in continuing operating activities of $6,551,087.

Our sources of liquidity and cash flows are used to fund ongoing operations, fund research and development projects for new products 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 business. In addition, as part of our business strategy, we are evaluating potential acquisitions of businesses, products and technologies or other strategic acquisitions. 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.

There are multiple risks that could result in economic uncertainty and volatility in the capital markets in the near term and could negatively affect our operations. We intend to continue to monitor the effects of inflation, global supply chain shortages, and general economic conditions, and, if appropriate, we may alter our plans to address such concerns as they may arise.

Management's plans are to focus on acquiring new customer orders, to further grow and expand our business in both commercial and military markets, and to respond to the changing economic landscape by continuing to control hiring and operating costs, conserve cash, and focus on growth and margin expansion. Management is committed to conserving cash and securing debt and/or equity financing, as required, for liquidity to meet our near-term cash requirements.

In April 2022, the Company obtained a domestic revolving line of credit of $2,000,000 at Torrey Pines Bank (the "Line of Credit"). To access the Line of Credit, the Company must maintain a minimum cash balance of $2,500,000 with the bank and maintain a maximum debt to tangible net worth of ratio of 1.00. The Line of Credit is also collateralized by the assets of the Company. The Line of Credit matures on September 11, 2026 and is subject to renewal thereafter. No balance was outstanding on either March 31, 2026 or December 31, 2025.

Additionally, in August 2023, we filed a new registration statement on Form S-3 (Registration No. 333-274073) with the SEC, which became effective on August 25, 2023, 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. In the event that we need additional financing, we may choose to consummate an offering of our securities under the registration statement on S-3 in order to raise capital.

On September 29, 2025, the Company entered into a Securities Purchase Agreement with certain institutional investors, pursuant to which the Company agreed to issue and sell to the investors in a registered direct offering 2,500,000 shares of the Company's common stock, par value $0.0001 per share. The common stock was sold pursuant to a prospectus supplement, filed October 1, 2025, supplementing the Registration Statement on Form S-3. Net proceeds of the offering were $11,565,146, which is comprised of gross proceeds of $12,500,000 less offering expenses of $934,854. The offering closed on October 1, 2025.

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 efforts will be effective or the forecasted cash flows will be achieved. Furthermore, we will continue to evaluate our capital expenditure needs based upon various factors, including but not limited to, our sales from operations, growth rate, the timing and extent of 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.

Cash from Continuing Operating Activities

During the three month period ended March 31, 2026, we generated $4,041,908 in cash from continuing operating activities, compared to cash used in continuing operating activities of $1,505,184 for the same period in 2025.

Net cash provided by continuing operating activities during the three month period ended March 31, 2026 was the result of three components: 1) net loss from continuing operations of $362,588; 2) net adjustments to net loss from continuing operations for non-cash items of $1,022,815, of which the largest components were stock-based compensation expense of $655,128 and depreciation expense of $184,151; and 3) a decrease in net operating assets associated with continuing operations of $3,381,681.

Cash provided from net changes in operating assets and liabilities for the three month period ended March 31, 2026 was $3,381,681, compared to cash provided by net changes in operating assets and liabilities of $90,285 in the same period of 2025. The change in cash from net changes in operating assets and liabilities was primarily driven by reductions in accounts receivable in the first three months of 2026 due to collections of billings from 2025.

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.

Cash from Continuing Investing Activities

During the three month period ended March 31, 2026, the Company used cash of $10,090,641 in continuing investing activities, as compared to $595,419 of cash provided by continuing investing activities during the same period in 2025. This change is primarily attributable to $10,075,640 of purchases of marketable securities during the three months ended March 31, 2026, as compared to $601,860 of sales of marketable securities in the same period in 2025.

Continuing Financing Activities

During the three month period ended March 31, 2026, the Company used $782,202 in cash from continuing financing activities, compared to $129,656 of cash generated from continuing financing activities for the same period in 2025. The change was due to higher payments of withholding taxes on stock-based awards, driven primarily by a higher share price on the vesting date for employee restricted stock units which vested in the period. Additionally, the Company received lower proceeds from the exercise of stock options in the three month period ended March 31, 2026 as compared to the same period in 2025, due to a lower number of options exercised in the period.

Known Trends or Uncertainties

With our shifted focus to the development and sale of edge computing products, we have significantly increased our efforts to penetrate the military and defense sectors in particular. These sectors typically have protracted sales cycles, significant contracting requirements, and multi-year deliverables. Our pipeline is generally affected by the procurement habits and timing of the military and defense sector.

29

Tariffs and the threat of tariffs, ongoing military conflicts, macroeconomic conditions and policy, inflation and the risk of inflation, and uncertainty about the timing and substance of U.S. government budgets and policy actions have contributed to uncertainty and capital markets volatility overall, which could negatively impact our operations.

We have received notifications from certain of our suppliers of extended lead times for certain components used in our products. In late 2025, a global shortage of certain memory products resulting from datacenter build-out demand led to significant increases in lead times, pricing volatility, and significant price increases. We have worked with our suppliers to secure availability of supply, including through the negotiation of long-term agreements. While we attempt to pass on component cost increases to our customers, our ability to do so is dependent upon many factors, including market conditions for the Company's products.

Inflation

We have recently experienced and continue to experience effects from inflation. Although the Company attempts to pass on increases in raw material, labor, energy and fuel-related costs to our customers, the Company's ability to do so is dependent upon the rate and magnitude of any increase, competitive pressures, and market conditions for the Company's products. There have been in the past, and may be in the future, periods of time during which increases in these costs cannot be fully recovered. These increasing costs are being aggressively managed by the Company and actions are being taken to minimize the impact to the Company. Inflation affects the Company's manufacturing costs, distribution costs, and operating expenses.

U.S. Government Budget Environment

In recent years, U.S. government appropriations have been affected by larger U.S. government budgetary issues and related legislation, and the U.S. government has been unable to complete its budget process before the end of its fiscal year, resulting in both governmental shutdowns and continuing resolutions providing only enough funds for U.S. government agencies to continue operating at prior-year levels. Our business and results of operations could be impacted by future disruptions to U.S. government operations, and these impacts could include delays in contract awards and new program starts. A prolonged shutdown could delay new awards and funding for defense-related projects involving U.S. government agencies and prime contractor customers. These delays could temporarily affect the timing of our revenue recognition, increase our working capital requirements, or reduce near-term liquidity.

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 9 to the accompanying consolidated 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.

30

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 the year ended December 31, 2025.

Interest rate risk

Our exposure to interest rate risk is primarily associated with borrowing on revolving lines of credit denominated in U.S. dollars. We are exposed to the impact of interest rate changes primarily through our borrowing activities for our variable rate borrowings. We did not have any outstanding balances on our line of credit as of March 31, 2026 or December 31, 2025.

Concentration of credit risk

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"), both of which provide basic deposit coverage with limits up to $250,000 per owner. As of March 31, 2026, the Company had $5,018,562 in cash in our accounts that exceeded the insurance limits. The Company has not experienced any losses in these accounts and believes that the financial institutions at which such amounts are held are stable; however, no assurances can be provided as to such.

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.

Foreign currency risk

We operate primarily in the United States. Foreign sales of products and services are primarily denominated in U.S. dollars. We have previously conducted business outside the United States, primarily through Bressner, our former foreign subsidiary in Germany, which was sold on December 30, 2025 and is classified as discontinued operations. Bressner's business was 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 have been subject to exposure from changes in the exchange rates of local currencies. Foreign currency transaction gains and losses associated with continuing operations are recorded in other income (expense), net in the consolidated statements of operations. Foreign currency transaction gains and losses associated with discontinued operations are recorded in income from discontinued operations, net of income taxes in the consolidated statements of operations.

The functional currency for the Bressner business was 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. With the divestiture of the Bressner business in 2025, cumulative currency translation adjustments associated with our Bressner business were released from accumulated other comprehensive income (loss) and recorded within income from discontinued operations, net of income taxes.

31

Derivative Financial Instruments

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 may 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.

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.

Adjusted EBITDA associated with our continuing operations for the three month periods ended March 31, 2026 and 2025 was as follows:

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.

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. 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.

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 continuing operating activities to free cash flow:

Item 3. Quantitative and Qualitati ve 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, 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 (based upon 2013 Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and 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 Quarterly 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, 2026, 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.
