PROXY STATEMENT FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON WEDNESDAY, MAY 13, 2026

The board of directors of One Stop Systems, Inc. (the “Company”) is soliciting the enclosed proxy for use at the Company's 2026 Annual Meeting of Stockholders (the “Annual Meeting”) to be held on Wednesday, May 13, 2026, at 11:00 a.m., Pacific Daylight time. You may attend the Annual Meeting virtually via the Internet at www.proxydocs.com/OSS, where you will be able to vote electronically and submit questions, after you register prior to commencement of the Annual Meeting.

GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why did you send me this proxy statement?

We sent you this proxy statement and the enclosed proxy card because our board of directors is soliciting your proxy to vote at the Annual Meeting. This proxy statement summarizes information related to the proposals being presented for your vote at the Annual Meeting. All stockholders who find it convenient to do so are cordially invited to attend the Annual Meeting virtually via the Internet at www.proxydocs.com/OSS. However, you do not need to attend the Annual Meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card, or complete and submit your proxy via phone or the internet in accordance with the instructions provided on the enclosed proxy card.

We intend to begin mailing this proxy statement, the accompanying notice of Annual Meeting, the enclosed proxy card, and our Annual Report on Form 10-K for the year ended December 31, 2025 (the “Annual Report”) to all stockholders of record entitled to vote at the Annual Meeting on or about April 14, 2026. Only stockholders who owned shares of our common stock as of the close of business on March 20, 2026 (the “Record Date”) are entitled to vote at the Annual Meeting. On Record Date, there were 24,769,017 shares of our common stock issued and outstanding. Common stock is our only class of stock outstanding and entitled to vote at the Annual Meeting.

What is the date, time and place of the Annual Meeting?

Our Annual Meeting will be held on Wednesday, May 13, 2026, beginning at 11:00 a.m., Pacific Daylight time. You may attend the Annual Meeting virtually via the Internet at www.proxydocs.com/OSS. To attend, you must register at any time in advance of the Annual Meeting at www.proxydocs.com/OSS. Upon completing your registration, you will receive further instructions via email, including your unique links that will allow you access to the virtual Annual Meeting, and you will also be able to submit questions in advance of the Annual Meeting.

What is the purpose of the Annual Meeting?

At the Annual Meeting, stockholders will act upon the matters outlined in the notice of meeting on the cover page of this proxy statement, consisting of the (i) election of five directors to hold office until our next annual meeting of stockholders or until their successors are duly elected and qualified, subject to prior death, resignation or removal; (ii) ratification of the selection of Haskell & White LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; (iii) approval of an amendment to our 2017 Equity Incentive Plan, as amended to date (the "2017 Plan"), to increase the number of shares of the Company's common stock authorized for issuance thereunder from 5,000,000 shares to 7,000,000 shares, pursuant to the terms and conditions of the 2017 Plan; iv) approval, on a non-binding advisory basis, of the compensation of our named executive officers; (v) approval of the adjournment of the Annual Meeting to another place, or a later date or dates, if necessary or appropriate, to solicit additional proxies in the event we have not received sufficient votes in favor of the foregoing proposals; and (vi) approval of such other matters that may properly come before the Annual Meeting or any adjournment or postponement thereof, if applicable.

Who is entitled to vote at the meeting?

Only our stockholders of record as of the close of business on March 20, 2026, the Record Date for the Annual Meeting, are entitled to receive notice of and to participate in the Annual Meeting. If you were a stockholder of record on that date, you will be entitled to vote all of the shares you held on that date at the Annual Meeting, or any postponement(s) or adjournment(s) of the Annual Meeting, if applicable. As of the Record Date, there were 24,769,017 shares of Company common stock issued and outstanding, all of which are entitled to be voted at the Annual Meeting.

A list of stockholders as of the Record Date will be available at our headquarters located at 2235 Enterprise Street #110, Escondido, California 92029 for a period of ten days prior to the Annual Meeting through the date of the Annual Meeting, and will also be made available at the Annual Meeting itself for examination by any stockholder.

What are the voting rights of the holders of our shares of common stock?

Holders of shares of our common stock as of the Record Date are entitled to one vote per share on each matter that is submitted to stockholders for approval at the Annual Meeting.

Who can attend the meeting?

All stockholders as of the Record Date, or their duly appointed proxies, may attend the Annual Meeting. Please also note that if you hold your shares in “street name” (that is, through a bank, broker or other nominee), you too will need to register separately prior to commencement of the Annual Meeting.

What constitutes a quorum?

Unless otherwise provided by law, the certificate of incorporation, or the second amended and restated bylaws adopted March 13, 2025 (the "Bylaws"), the holders of the majority of the voting power of the capital stock issued and outstanding and entitled to vote as of the Record Date, present in person, or by remote communication, if applicable, or represented by proxy, shall constitute a quorum, permitting the Annual Meeting to conduct its business. As of the Record Date, there were 24,769,017 shares of our common stock issued and outstanding, all of which are entitled to be voted at the Annual Meeting.

What vote is required to approve each item?

The election of directors will be decided by a plurality of the votes cast. Accordingly, the nominees receiving the support of stockholders representing the greatest numbers of shares of common stock present at the

meeting, virtually or by proxy and entitled to vote, shall be elected as directors. Abstentions and votes “against” will have no effect on the outcome of this proposal.

Although directors shall be elected by a plurality of votes cast, in an uncontested election of directors, any director nominee who receives a greater number of votes "against" than votes "for" (excluding abstentions) his or her election must promptly tender his or her resignation. Following receipt of such resignation, the Nominations and Corporate Governance Committee of the Company's Board of Directors will consider the resignation and recommend to the Board whether to accept such tendered resignation. Except in special circumstances, the Committee will be expected to accept and recommend acceptance of the resignation by the Board.

The affirmative vote of the holders of a majority in voting power of the votes cast affirmatively or negatively (excluding abstentions) at the Annual Meeting by the holders entitled to vote thereon is required for the approval of each of the other proposals being presented to our stockholders for approval at the Annual Meeting.

The inspector of election for the Annual Meeting shall determine the number of shares of common stock represented at the Annual Meeting, the existence of a quorum and the validity and effect of proxies, and shall count and tabulate ballots and votes and determine the results thereof. Proxies received but marked as abstentions or broker non-votes will be included in the calculation of the number of shares considered to be present at the Annual Meeting for purposes of determining a quorum.

A “broker non-vote” will occur when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary power with respect to that proposal and has not received instructions from the beneficial owner. We believe that the ratification of the selection of Haskell & White LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026 is the only proposal on which brokers and other nominees will have discretionary power to vote at the Annual Meeting. However, broker non-votes will not be counted as votes cast for any of the proposals being presented to our stockholders for approval at the Annual Meeting, and therefore will have no effect on the outcome of any of the proposals.

If less than a majority of the combined voting power of the issued and outstanding shares of our common stock as of the Record Date is represented at the Annual Meeting, then the chairperson of the Annual Meeting or a majority of the shares so represented may adjourn the Annual Meeting from time to time without further notice, unless otherwise required by our Bylaws or applicable law.

What are the Board’s recommendations?

As more fully discussed under the section of this proxy statement entitled “Matters to Come Before the Annual Meeting,” our board of directors recommends a vote (i) FOR the election of each of the respective nominees for director named in this proxy statement; (ii) FOR the ratification of the selection of Haskell & White LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026; (iii) FOR the approval of the amendment to the 2017 Plan to increase the number of shares of the Company's common stock authorized for issuance thereunder from 5,000,000 shares to 7,000,000 shares, pursuant to the terms and conditions of the 2017 Plan; (iv) FOR the approval, on a non-binding advisory basis, of the compensation of our named executive officers; and (v) FOR adjournment of the Annual Meeting, if necessary or appropriate, to solicit additional proxies.

Unless contrary instructions are indicated on the enclosed proxy card, all shares represented by valid proxies received pursuant to this solicitation (and which have not been revoked in accordance with the procedures set forth below) will be voted (i) FOR the election of each of the respective nominees for director named in this proxy statement; (ii) FOR the ratification of the selection of Haskell & White LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026, (iii) FOR the approval of the amendment to the 2017 Plan to increase the number of sharee Company's common stock authorized for issuance thereunder from 5,000,000 shares to 7,000,000 shares, pursuant to the terms and conditions of the 2017 Plan; (iv) FOR the approval, on a non-binding advisory basis, of the compensation of our named executive officers; (v) FOR adjournment of the Annual Meeting, if necessary or appropriate, to solicit

additional proxies; and (vi) in accordance with the recommendation of our board of directors, FOR, AGAINST, or ABSTAIN, for all other matters as may properly come before the Annual Meeting or any adjournment or postponement thereof, if applicable. In the event a stockholder specifies a different choice by means of the enclosed proxy, such shares will be voted in accordance with the specification made.

How do I vote?

If you are a holder of record (that is, if your shares are registered in your own name with our transfer agent), you may vote using the enclosed proxy card or those other methods noted on the enclosed proxy card. Voting instructions are provided on the proxy card included in the proxy materials you receive in the mail.

If you are a street name holder (that is, if you hold your shares through a bank, broker, or other nominee), you must vote in accordance with the voting instruction form provided by your bank, broker or other holder of record. The availability of telephone or Internet voting will depend upon your bank’s, broker’s, or other holder of record’s voting process.

If you virtually attend the Annual Meeting, you can, of course, vote virtually at the Annual Meeting. If you are a street name holder and wish to vote at the meeting, you must first obtain a legal proxy from your bank, broker or other holder of record authorizing you to vote.

If my shares are held in “street name” by a broker or other nominee, will my broker or nominee vote my shares for me?

If your shares are held in “street name” and you do not instruct your broker, bank or other nominee on how to vote your shares, your broker, bank or other nominee may exercise its discretion to vote your shares only on “routine” matters.

The proposal to ratify the selection of Haskell & White LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026 is considered a routine matter. Therefore, your broker, bank or other nominee will be able to vote on that proposal, even if it does not receive voting instructions from you.

We believe that all of the other proposals being presented to our stockholders for approval at the Annual Meeting are considered nonroutine matters. Consequently, without your voting instructions, your broker, bank or other nominee will not be able to vote your shares on such proposals without voting instructions from you.

Are dissenters’ rights available with respect to any proposal?

Dissenters’ rights are not available with respect to any proposal to be voted on at the Annual Meeting.

Can I change my vote after I return my proxy card?

Yes. The giving of a proxy does not eliminate the right to vote virtually should any stockholder giving the proxy so desire. Stockholders have an unconditional right to revoke their proxy at any time prior to the exercise of that proxy at the Annual Meeting.

If you have not voted through your bank, broker or other nominee, there are three ways for you to revoke your proxy and change your vote. First, you may send a written notice to the Company’s Secretary stating that you would like to revoke your proxy. Second, you may complete and submit a new proxy, but it must bear a later date than the original proxy. Third, you may vote virtually at the Annual Meeting. However, your attendance at the Annual Meeting will not, by itself, revoke your proxy.

If you have instructed a bank, broker or other nominee to vote your shares, you must follow the directions you receive from them to change your vote. Your last submitted proxy will be the proxy that is counted.

Who pays for costs relating to the proxy materials and Annual Meeting?

The costs of preparing, assembling, and mailing this proxy statement, the Notice of Annual Meeting of Stockholders, the enclosed Annual Report and the proxy card, along with the cost of posting the proxy materials on a website, are to be borne by us. In addition to the use of mail, our directors, officers, and employees may solicit proxies personally or by telephone, facsimile, and other electronic means. They will receive no compensation in addition to their regular salaries for doing so. We may request banks, brokers and other custodians, nominees, and fiduciaries to forward copies of the proxy material to their principals and to request authority for the execution of proxies. We may reimburse these persons for their expenses in so doing.

How can I find out the results of the voting?

We intend to announce preliminary voting results at the Annual Meeting and publish final results in a Current Report on Form 8-K within four business days following the Annual Meeting.

MATTERS TO COME BEFORE THE ANNUAL MEETING

PROPOSAL 1:

Election of Directors

Nomination of Directors

The Nominations and Corporate Governance Committee of our board of directors (the “Nominations Committee”) is charged with making recommendations to our board of directors regarding qualified candidates to serve as members of the board of directors. The Nominations Committee’s goal is to assemble a board of directors with the skills and characteristics that, taken as a whole, will assure a strong board of directors with experience and expertise relevant to our business and the industries in which we operate, corporate governance practices, risk management, and the capital markets. The Nominations Committee believes that candidates for director should have certain minimum qualifications or skills, including personal integrity, strength of character, an inquiring and independent mind, practical wisdom, and mature judgment. In evaluating director nominees, the Nominations Committee considers the following factors:

The appropriate size of the board of directors;

The Company’s needs with respect to the particular talents and experience of its directors;

The knowledge, skills, and experience of nominees, including without limitation experience in technology, business, finance, the industries that we target, risk management, artificial intelligence, conflict resolution, corporate governance, cultural competence, leadership, administration, and/or public service; and

Relevant Nasdaq, Securities and Exchange Commission (“SEC”), state, and investor recommendations and requirements.

Other than as required by Nasdaq, the SEC or other state rules and regulations, there are no stated minimum criteria for director nominees, and the Nominations Committee may consider such other factors as it deems to be in the Company’s and its stockholders’ best interests. The Nominations Committee does, however, believe it appropriate for at least one member of the board of directors to meet the criteria for an “audit committee financial expert,” as defined by SEC rules, and for a majority of the members of the board of directors to meet the definition of an “independent director” under Nasdaq listing standards.

The Nominations Committee identifies nominees by first evaluating the current members of the board of directors willing to continue in service. Current members of the board of directors with skills and experience that are relevant to our business and who are willing to continue in service are considered for re-nomination, but the Nominations Committee at all times seeks to balance the value of continuity of service by existing members of the board of directors with that of obtaining a new perspective. In the event that the Nominations Committee determines that an existing member is no longer the best suited candidate to serve as a director of the Company going forward, or if any member of the board of directors does not wish to continue in service, the Nominations Committee’s policy is to not re-nominate that member for reelection. The Nominations Committee identifies the desired skills and experience of prospective nominees, and then uses its network and external resources to solicit and compile a list of eligible candidates.

Our Nominations Committee has, from time to time, received correspondence from stockholders that it considers, researches and actively takes into account in making recommendations to the Board with respect to prospective director nominees and other relevant matters. Stockholders wishing to recommend a candidate for consideration by the Nominations Committee as a prospective nominee for election as a director may do so by contacting the chair of our Nominations Committee and providing information regarding such proposed candidate. Alternatively, stockholders who wish to nominate alternative individuals for election at our annual meetings of stockholders may do so by following the process outlined in Section 2.5 of our Bylaws, as amended to date, and Rule 14a-19 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and sending a written notice to the Nominations Committee, Attn: Chairman, One Stop Systems, Inc., 2235 Enterprise St.

#110, Escondido, CA 92029, naming the proposed candidate and providing detailed biographical, contact and other required information regarding such proposed candidate.

To our knowledge, there are currently no legal proceedings, and during the past ten years there have been no legal proceedings, that we believe are required to be disclosed pursuant to Item 4.01(f) of Regulation S-K. There are no material proceedings to which any director, officer, affiliate, or owner of record or beneficial owner of more than 5% of any class of voting securities of the Company, or any associates of any such persons, is a party adverse to the Company or any of our subsidiaries, and to our knowledge, none of such persons has a material interest adverse to the Company or any of its subsidiaries. Other than as disclosed below, during the last five years, none of our directors held any other directorships in any company with a class of securities registered pursuant to Section 12 of the Exchange Act, or subject to the requirements of Section 15(d) of the Exchange Act or any company registered as an investment company under the Investment Company Act of 1940.

Our board of directors has undergone a significant reprofiling over the past three years in order to further align its skillsets with the Company’s revised strategic direction and in response to feedback received by stockholders. As part of the Board’s reprofiling process, it considered adding members who have significant expertise with the military, service in the military or in the defense contracting industry, the technology industry, commercial markets, senior executive experience, corporate governance expertise and capital markets and investment experience. Additionally, it considered the importance of the continuity of service and familiarity of certain board members with the Company and our practices. After extensive independent research as to corporate governance best practices and discussion among members of our board of directors, the Nominations Committee recommended the slate set forth below for election by our stockholders at the Annual Meeting.

Our board of directors is committed to employing strong corporate governance practices for companies of similar size to One Stop Systems, Inc. The Nominations Committee and the board as a whole review our corporate governance policies and practices on an annual basis to determine whether changes are necessary or appropriate in order to align with best practices and to enhance stockholder value. To that end, the board of directors considers stockholder recommendations with respect to the Company’s corporate governance practices and procedures, as well as those practices of its peers and other public companies similar in size and industry as the Company.

The Nominations Committee has recommended, and our board of directors has nominated, Mitchell Herbets, Michael Knowles, Greg Matz, Retired Vice Admiral Mike Dumont, and Retired Lieutenant General David Bassett as nominees for election as members of our board of directors at the Annual Meeting, to hold office until our next annual meeting of stockholders or until such director’s successor is duly elected and qualified, subject to such director’s earlier death, resignation or removal.

Board of Directors

Mitchell H. Herbets joined our board of directors in November 2023 where he has served as chairman since May 2025. Mr. Herbets currently serves as non-executive chairman of Thales Defense and Security, a global technology company that provides advanced technology equipment to the U.S. defense, federal and international technology markets. His other current chairman positions include: Safran Federal Systems, a provider of resilient positioning, navigation and timing (PNT) solutions, AI intelligence systems, and custom engineering services to federal agencies, defense organizations and contractors; Photonis Defense, a provider of advanced products in night and digital vision technologies to U.S. and allied governments, and iDirect

Government, a provider of tactical satellite communications systems to U.S. Primes for the U.S. Department of Defense. Mr. Herbets previously served on the board of Wireless Telecom Group (WTT), a NYSE American-listed provider of infrastructure for cellular systems, LTE and 5G waveforms, and telecommunications test equipment company before it was acquired by Maury Microwave in 2023. He earlier served as president and CEO of Thales Communications (now Thales Defense and Security), a global leader in tactical radio technology. Prior to being appointed as president and CEO of Thales, he served in a number of senior executive positions at the company, including leadership roles in program management, engineering, and business development. Before Thales, he served four years in the U.S. Army with the final rank of captain. He holds a bachelor’s degree in electrical engineering from Lehigh University, where he currently serves as a member of the advisory council of Lehigh University’s Engineering College. He earned his MBA from George Washington University. Our board of directors believes Mr. Herbets’ significant experience as a senior executive in the defense technology industry, corporate governance experience, organizational leadership skills, and experience serving on the boards of public companies align with the desired skill sets identified by the nominating and governance committee making him well suited to serve as a member of our board of directors. In addition to serving as chairman, Mr. Herbets has played a key role as the chair of the compensation committee. His experience as a CEO has provided valuable insight, consultation, and peer review for the company CEO and CFO in the conduct of business, development of strategy and execution of overall growth strategy plans. He also has helped establish connections with influencers and business opportunities within the defense markets. Lastly, he has provided leadership mentoring for members of the executive staff. The CEO and executive management team look to take advantage of these same contributions going forward.

Mike Knowles has served as our president and chief executive officer since June 2023 and as a director on our board since September 2023. He has more than three decades of leadership experience in global aerospace and defense markets, having led successful business captures resulting in billion-dollar program and product portfolios. Prior to joining the Company, Mr. Knowles served as vice president and general manager of C5ISR Systems at Curtiss Wright Defense Solutions from October 2022 to June 2023. Prior to that, from May 2014 to October 2022, Mr. Knowles worked at Cubic Corporation (“Cubic”), where he served in various roles, culminating in his roles as a senior vice president of Cubic and president of Cubic’s Mission and Performance Solutions business, in which role he led a $700 million global business unit with 2,000 employees. While at Cubic, his C5ISR hardware, software and solutions portfolios included rugged networking/computing at the edge, secure and expeditionary communications, intelligence processing, assessment distribution from enterprise-to-edge, high frequency/low SWAP RF components for electronic warfare, space, and 5G applications; and live, virtual, and constructive (LVC) multi-domain training systems. Before Cubic, Mr. Knowles worked at Rockwell Collins from 2004 to 2014 and at Lockheed Martin from 1998 to 2003, both of which are well recognized defense contractors. Prior to that, Mr. Knowles served in the United States Navy for 20 years as a Naval Flight Officer and Aerospace Engineering Duty Officer, with 10 years active duty and 10 years in the Navy Reserves, where he retired as a Commander. He received a BS in Aerospace Engineering from the United States Naval Academy, an MS in Aerospace Engineering from the Naval Postgraduate School, was a graduate of the US Naval Test Pilot School, and received an MBA from George Mason University.

Our board of directors believes Mr. Knowles’ senior leadership experience in the defense and technology industries, coupled with the fact that Mr. Knowles serves as the Company’s president and chief executive officer, make him well suited to serve as a member of our board of directors.

Greg Matz, CPA, joined our board of directors in July 2020, and is an experienced financial executive, having served in controller, Vice President, and CFO roles for over two decades. Now retired, Mr. Matz is currently serving as a member of the board of directors and audit committee chair for Dare Bioscience, Inc. (NASDAQ: DARE), a public clinical-stage biopharmaceutical company. From 2011 to 2016, he worked for The Cooper Companies, Inc. (NYSE: COO), holding roles as the Senior Vice President and Chief Financial Officer and Chief Risk Officer. From 2010 to 2011, Mr. Matz was the Chief Financial Officer for CooperVision, a business unit of The Cooper Companies, Inc. Prior to joining The Cooper Companies, Inc., he held key management roles in finance and marketing at Agilent Technologies and Hewlett Packard. He began his career at KPMG and is a CPA with an active certification. Mr. Matz graduated from the University of San Francisco with a B.S. in Business Administration and completed the University of Pennsylvania, The Wharton School’s Advanced Management Program. Mr. Matz is also a National Association of Corporate Directors (“NACD”) Board Leadership Fellow and has earned the NACD Directorship Certification credential. In addition, Mr. Matz has received a certification from NACD / Carnegie Mellon University in Cybersecurity Oversight. Our Board

believes Mr. Matz’s experience as a chief financial officer and chief risk officer of a public company including his corporate experience and skills in financial functions, including planning, reporting, and audit, in risk management, in managing internal growth and acquisitions and in capital markets and corporate strategy qualifies him to serve as a member of our Board and to fill the important role of “audit committee financial expert.”

Michael Dumont joined our board of directors in September 2023 after having served on our board of advisors. He is a retired United States Navy three-star admiral and former senior executive in the U.S. Government with extensive experience in national security, aerospace and defense, risk management, and organizational leadership. During his career in government, Admiral Dumont served in senior leadership roles within the U.S. Department of Defense, including as Principal Deputy Assistant Secretary of Defense for Special Operations and Low-Intensity Conflict, Deputy Commander of U.S. Northern Command, and Vice Commander of the North American Aerospace Defense Command. Earlier in his career, he served as a federal prosecutor specializing in white-collar and corporate matters. Admiral Dumont most recently served as a university president and currently advises companies developing artificial intelligence technologies for defense, national security, and public safety applications. He holds a B.A. from the University of Southern Maine, an M.S. from the National War College, and a J.D. from Suffolk University Law School. He is a member of the National Association of Corporate Directors and holds the NACD Directorship Certification. The Company believes Admiral Dumont’s extensive leadership experience in national security, and government policy, as well as his expertise in corporate governance, risk management, and emerging technologies, qualifies him to serve on the Company’s Board of Directors.

David Bassett joined our board in May 2025 and is a retired Army Lieutenant General with a distinguished 35-year military career. Lieutenant General Bassett’s career includes extensive leadership driving military modernization and managing large-scale acquisitions. From 2020-2023, he served as Director of the Defense Contract Management Agency (DCMA), where he led more than 11,000 civilian and military personnel who managed more than 250,000 contracts with total value in excess of $3.5 trillion. Prior to his role at DCMA, he served as Program Executive Officer for Command, Control, and Communications-Tactical (PEO C3T), where he led critical modernization priorities, including around development and acquisition of the Army’s tactical network.

Vote Required

The election of directors will be decided by a plurality of the votes cast. If a quorum is present and voting at the Annual Meeting, the five nominees receiving the highest number of “for” votes will be elected to our board of directors. Abstentions, votes “against” and broker non-votes will be counted only for purposes of determining whether a quorum is present, but will have no effect on the outcome of this proposal.

However, in accordance with Sections 3.3 and 3.4 of the Bylaws, in an uncontested election of directors, any director nominee who receives a greater number of votes "against" than votes "for" (excluding abstentions) must promptly tender his or her resignation from the board. Following receipt of such resignation, the Nominations Committee will consider the resignation and recommend to the board of directors whether to accept

such tendered resignation. Except in special circumstances, the Nominations Committee will be expected to accept and recommend acceptance of the resignation by the board of directors.

RECOMMENDS A VOTE FOR THE ELECTION OF EACH NOMINEE LISTED IN THIS

PROPOSAL 1.

PROPOSAL 2:

Ratification of Selection of Independent Registered Public Accounting Firm

Our audit and risk committee has selected Haskell & White LLP (“H&W”) as the Company’s independent registered public accounting firm for the year ending December 31, 2026, and has further directed that management submit the selection of independent registered public accounting firm for ratification by the Company’s stockholders at the Annual Meeting. H&W has audited the Company’s financial statements since 2017. Representatives of H&W are expected to be present at the Annual Meeting, will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions.

Stockholder ratification of the selection of H&W as the Company’s independent registered public accounting firm is not required by Delaware law, the Company’s amended and restated certificate of incorporation, or the Company’s Bylaws, as amended. However, our audit and risk committee is submitting the selection of H&W to our stockholders for ratification as a matter of good corporate practice. Although this is a non-binding vote, if our stockholders fail to ratify the selection, the audit and risk committee will reconsider whether to continue to retain H&W as the Company’s registered public accounting firm. Even if the selection is ratified, our audit and risk committee, in its discretion, may direct the appointment of a different independent registered accounting firm at any time during the year if the audit and risk committee determines that such a change would be in the best interests of the Company and its stockholders.

Independent Registered Public Accounting Firm’s Fees

The following table represents aggregate fees billed to us for services rendered to us by H&W, our independent registered public accounting firm, related to the fiscal years ended December 31, 2025 and 2024:


	For the Year Ended December 31,
	2025		2024
Audit fees (1)	$	281,350	$	272,500
Audit-Related fees (2)		7,500		5,000
Tax fees		-		-
Other fees		-		-
Total fees	$	288,850	$	277,500

Includes fees for (i) audits of our consolidated financial statements for the fiscal years ended December 31, 2025 and 2024, and (ii) reviews of our interim period financial statements for fiscal years 2025 and 2024.

Review of Form S-3 and Form S-8, and supplements thereto, including preparation of consents.

Pre-Approval Policies and Procedures

Our audit and risk committee pre-approves all auditing services and the terms of non-audit services provided by our independent registered public accounting firm, but only to the extent that the non-audit services are not prohibited under applicable law and the committee determines that the non-audit services do not impair the independence of the independent registered public accounting firm.

In situations where it is impractical to wait until the next regularly scheduled meeting, the chairman of the committee has been delegated authority to approve audit and non-audit services to be provided by our independent registered public accounting firm. Fees payable to our independent registered public accounting firm for any specific, individual service approved by the chair pursuant to the above-described delegation of authority may not exceed $25,000, and the chair is required to report any such approvals to the full committee at its next scheduled meeting. In addition, our audit and risk committee has pre-approved a list of acceptable services and fees payable to H&W in an aggregate amount of up to $18,500 per quarter for such services, including without limitation audit and allowable non-audit and tax consulting. This pre-approval is for small projects needing quick

reaction and judged by our audit and risk committee not to raise any independence issues with H&W. Such projects and fees are required to be presented in detail at the next audit and risk committee meeting. Fees that were incurred in 2025 and 2024 were pre-approved by our audit and risk committee.

Our audit and risk committee has considered and determined that the provision of the non-audit services described is compatible with maintaining the independence of our registered public accounting firm.

Vote Required

The affirmative vote of the holders of a majority of the votes cast at the Annual Meeting by the holders entitled to vote thereon is required to ratify the selection of H&W as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Abstentions and broker non-votes, if any, will be counted only for purposes of determining whether a quorum is present. Abstentions will not be considered in tallying votes with respect to this Proposal and will have no effect on the outcome of the voting results for this Proposal. The approval of Proposal 2 is a routine proposal on which a broker or other nominee has discretionary authority to vote. Accordingly, no broker non-votes will likely result from this Proposal. In the event that there are any broker non-votes, they will not be considered in tallying votes with respect to this Proposal 2 and will have no effect on the outcome of the voting results for this Proposal.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY

RECOMMENDS A VOTE FOR THE RATIFICATION OF THE SELECTION OF HASKELL & WHITE LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026 IN THIS PROPOSAL 2.

PROPOSAL 3:

Approval of the Plan Amendment

At the Annual Meeting, our stockholders will be asked to approve an amendment (the "Plan Amendment") to the Company's 2017 Equity Incentive Plan (the "2017 Plan") to increase the number of shares of the Company's common stock authorized for issuance thereunder from 5,000,000 shares to 7,000,000 shares of common stock. Following this increase, the total number of shares authorized for issuance under the 2017 Plan, as amended, would represent approximately 28% of our issued and outstanding shares of common stock as of the Record Date.

Background and Proposed Plan Amendment

On October 10, 2017, our board of directors approved and adopted the 2017 Plan, subject to stockholder approval thereof. On December 18, 2017, our stockholders approved the 2017 Plan. The 2017 Plan allows for the grant of a variety of equity vehicles to provide flexibility in the grant and issuance of equity awards, including stock options, unrestricted stock grants, restricted stock units, stock bonuses and performance-based awards. An aggregate of 1,500,000 shares of common stock were initially reserved for issuance under the 2017 Plan.

On June 24, 2020, the Company 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. The amendment did not increase the total number of shares of common stock reserved under the 2017 Plan, and did not require stockholder approval.

On April 6, 2021, our board of directors unanimously approved an amendment to the 2017 Plan, subject to stockholder approval thereof, to increase the number of shares of common stock authorized for issuance under the 2017 Plan from 1,500,000 shares to 3,000,000 shares of common stock. On May 19, 2021, our stockholders approved the foregoing amendment, and the amendment took effect upon receipt of stockholder approval.

On March 15, 2024, our board of directors unanimously approved an amendment to the 2017 Plan, subject to stockholder approval thereof, to increase the number of shares of common stock authorized for issuance under the 2017 Plan from 3,000,000 shares to 5,000,000 shares of common stock. On May 15, 2024, our stockholders approved the foregoing amendment, and the amendment took effect upon receipt of stockholder approval.

On April 10, 2026, our board of directors unanimously approved the Plan Amendment, subject to stockholder approval thereof, which if approved by our stockholders, would result in an increase in the number of shares of common stock authorized for issuance thereunder to 7,000,000 shares of common stock. Our board of directors has directed that the Plan Amendment be submitted to our stockholders for their approval at the Annual Meeting. If approved by our stockholders, the Plan Amendment will be effective as of the date of such approval.

As of March 31, 2026, approximately 4,329,745 shares of our common stock were subject to outstanding awards issued under the 2017 Plan and approximately 670,255 shares of common stock were available for future awards under the 2017 Plan. Our board of directors believes that an increase in the number of authorized shares of common stock issuable under the 2017 Plan is necessary for the continued optimal use of the 2017 Plan.

Reasons for Approval of the Plan Amendment

Our board of directors believes that our interests and the interests of our stockholders will be advanced if we can continue to offer our employees, notably at the senior management level, advisors, consultants, and non-employee directors the opportunity to acquire or increase their proprietary interests in the Company. The market for quality personnel is competitive, and our board of directors has concluded that our ability to attract, retain and motivate top quality management and employees is material to our success, which would be significantly enhanced by our continued ability to grant equity compensation under the 2017 Plan. We believe

that adoption of the Plan Amendment will enhance our ability to attract and retain highly qualified officers, directors, employees, and service providers, and to motivate such individuals to serve the Company and to expend maximum effort to improve our business results by providing to those individuals an opportunity to acquire or increase a direct proprietary interest in our operations and future success. In the absence of the Plan Amendment, we believe that it will be more difficult to incentivize such individuals and it may require us to make additional cash payments to such individuals as an alternative. Accordingly, our board of directors has determined that the number of shares available for issuance under the 2017 Plan should be increased by 2,000,000 shares to allow us to continue our equity compensation structure and strategy.

If our stockholders do not approve the Plan Amendment at the Annual Meeting, the Plan Amendment will not become effective and the number of shares of common stock authorized for issuance under the Plan will remain at 5,000,000 shares of common stock. If we are unable to incentivize our current officers and directors through equity awards, we may face difficulties retaining them and/or may have to make additional cash payments in lieu of equity awards, which could negatively impact our results of operations.

Description of the 2017 Plan

The principal provisions of the 2017 Plan are summarized below. This summary is not a complete description of all of the 2017 Plan's provisions and is qualified in its entirety by reference to the full text of the 2017 Plan, a copy of which is attached as Exhibit 10.4 to the Annual Report, as amended by (i) that certain Amendment No. 1 to the 2017 Plan, which is filed as Exhibit 10.8 to the Annual Report, and (ii) that certain Amendment No. 2 to the 2017 Plan, which is filed as Exhibit 10.10 to the Annual Report. Capitalized terms in this summary that are not otherwise defined in this proxy statement shall have the same meanings as set forth in the 2017 Plan.

Purpose of the 2017 Plan

The purpose of the 2017 Plan is to i) provide additional incentive for selected Employees, Directors and Consultants to further the growth, development, and financial success of the Company by providing a means by which such persons may personally benefit through the ownership of capital stock of the Company, and ii) enable the Company to secure and retain key Employees, Directors and Consultants considered important to the long-term success of the Company by offering such persons an opportunity to own capital stock of the Company.

Form of Awards

Stock Awards under the Plan may be granted in any one or all of the following forms: (i) Incentive Stock Options, (ii) Nonstatutory Stock Options, (iii) Restricted Stock awards, (iv) Restricted Stock Units, (v) Stock Bonus awards, and (vi) Performance-Based Awards.

Maximum Shares Available

The current maximum aggregate number of shares of common stock available for award under the 2017 Plan is 5,000,000 shares, of which approximately 4,329,745 shares are subject to outstanding awards previously issued under the 2017 Plan, subject to adjustment as provided for in the 2017 Plan. Shares of common stock issued pursuant to the 2017 Plan may be either authorized but unissued shares or issued shares reacquired by the Company. In the event that (a) all or any portion of any Stock Award granted or offered under the 2017 Plan can no longer under any circumstances be exercised or otherwise become vested, or (b) any Award Shares are reacquired by the Company, which were initially the subject of a Stock Award Agreement, the Award Shares allocable to the unexercised or unvested portion of such Stock Award, or the Award Shares so reacquired, shall again be available for grant or issuance under the 2017 Plan.

Administration of the Plan

The 2017 Plan shall be administered by the Board, unless and until the Board delegates administration to a Committee or an Officer.

The Board may delegate administration of the 2017 Plan to a committee of the Board composed of not fewer than two members (the "Committee"). If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the 2017 Plan, as amended, the powers theretofore possessed by the Board (and references in the 2017 Plan to the Administrator shall thereafter be deemed to be references to the Committee), subject, however, to such resolutions, not inconsistent with the provisions of the 2017 Plan, as may be adopted from time to time by the Board. The Board may abolish the Committee at any time and revest in the Board the administration of the 2017 Plan. Appointment of Committee members shall be effective upon acceptance of appointment. In its sole discretion, the Board may at any time and from time to time exercise any and all rights and duties of the Administrator under the 2017 Plan except with respect to matters which under Rule 16b-3 under the Exchange Act or Section 162(m) of the Code, or any regulations or rules issued thereunder, are required to be determined in the sole discretion of the Committee. Committee members may resign at any time by delivering written notice to the Board. Vacancies in the Committee may only be filled by the Board.

In the discretion of the Board, the Committee may consist solely of two or more Outside Directors, in accordance with Section 162(m) of the Code, and/or solely of two or more Non-Employee Directors, in accordance with Rule 16b-3 of the Exchange Act. In addition, the Board or the Committee, in its discretion, may (1) delegate to a committee of one or more members of the Board who need not be Outside Directors the authority to grant Stock Awards to eligible persons who are either (a) not then Covered Employees and are not expected to be Covered Employees at the time of recognition of income resulting from such Stock Award, or (b) not persons with respect to whom the Company wishes to comply with Section 162(m) of the Code, and/or (2) delegate to a committee of one or more members of the Board who need not be Non-Employee Directors the authority to grant Stock Awards to eligible persons who are not then subject to Section 16 of the Exchange Act.

Eligibility to Participate in the 2017 Plan

The persons eligible to receive Stock Awards under the 2017 Plan are the Employees, Directors and Consultants of the Company and its Affiliates.

Incentive Stock Options may be granted only to Employees; all other Stock Awards may be granted only to Employees, Directors and Consultants. In the event a Participant is both an Employee and a Director, or a Participant is both a Director and a Consultant, the Stock Award Agreement shall specify the capacity in which the Participant is granted the Stock Award; provided, however, if the Stock Award Agreement is silent as to such capacity, the Stock Award shall be deemed to be granted to the Participant as an Employee or as a Consultant, as applicable.

Stock Options

Stock Options may be granted under the 2017 Plan for the purchase of shares of common stock. The Administrator may designate Stock Options as either Incentive Stock Options or Nonstatutory Stock Options. No grant of an Incentive Stock Option will be exercisable after the expiration of ten years from the date of its grant or such shorter period specified in the Option Agreement.

In general, the exercise price of each Incentive Stock Option shall be not less than the Fair Market Value of the common stock subject to the Option on the date the Option is granted. The Administrator shall determine the exercise price of each Nonstatutory Stock Option. Notwithstanding the foregoing, an Incentive Stock Option may be granted with an exercise price lower than one hundred percent (100%) of the Fair Market Value of the common stock subject to the Option if such Incentive Stock Option is granted pursuant to an assumption of or substitution for another option in a manner consistent with the provisions of Section 424(a) of the Code.

Options may be exercised in whole or in part. Payment of the purchase price upon the exercise of Options may be made in (i) cash or check, (ii) pursuant to a program developed under Regulation T as promulgated by the Federal Reserve Administrator, (iii) by delivery to the Company of shares of common stock, (iv) by a “net exercise” arrangement, or (v) any other form of legal consideration acceptable to the Administrator.

Restricted Stock Award

Restricted Stock Awards may be granted under the 2017 Plan. Restricted Stock Awards are grants of shares of common stock that vest in accordance with terms and conditions established by the Administrator. The Administrator will determine the number of shares of restricted stock granted to any Employee, Director or Consultant and, subject to the provisions of the 2017 Plan, will determine the terms and conditions of such awards. The Administrator may impose whatever conditions to vesting it determines to be appropriate. Award Shares acquired under the Restrictive Stock Award Agreement may, but need not to, be subject to a share repurchase option in favor of the Company in accordance with a vesting scheduled to be determined by the Administrator.

Restricted Stock Units

The Administrator is authorized to make Awards of Restricted Stock Units to any Participant selected by the Administrator in such amounts and subject to such terms and conditions as determined by the Administrator. At the time of grant, the Administrator shall specify the date or dates on which the Restricted Stock Units shall become fully vested and nonforfeitable, and may specify such conditions to vesting as it deems appropriate. Alternatively, Restricted Stock Units may become fully vested and nonforfeitable pursuant to the satisfaction of one or more Performance Goals or other specific performance goals as the Administrator determines to be appropriate at the time of the grant of the Restricted Stock Units or thereafter, in each case on a specified date or dates or over any period or periods determined by the Administrator. At the time of grant, the Administrator shall specify the maturity date applicable to each grant of Restricted Stock Units which shall be no earlier than the vesting date or dates of the Award and may be determined at the election of the Participant to whom the Award is granted.

Stock Bonus Awards

Stock Bonus Awards may be granted under the 2017 Plan. The Administrator will determine the number of Stock Bonus Awards granted to any Employee, Director or Consultant and, subject to the provisions of the 2017 Plan, will determine the terms and conditions of such awards. The Administrator may impose whatever conditions to vesting it determines to be appropriate.

Performance-Based Awards

The 2017 Plan provides the Administrator with the ability to qualify Stock Awards other than Options as Qualified Performance-Based Compensation.

With respect to Performance-Based Awards, the Administrator will specify performance objectives that must be satisfied in order for the Participant to vest in such Performance-Based Award that have been awarded to him or her. In determining the amount earned by the Participant, the Administrator shall have the right to reduce or eliminate (but not to increase) the amount payable at a given level of performance to take into account additional factors that the Administrator may deem relevant to the assessment of individual or corporate performance for the Performance Period.

Unless otherwise provided in the applicable Stock Award Agreement, a Participant must be employed by the Company or a Parent or Subsidiary on the day a Performance-Based Award for such Performance Period is paid to the Participant. Furthermore, a Participant shall be eligible to receive payment pursuant to a Performance-Based Award for a Performance Period only if the Performance Goals for such period are achieved.

Assignment and Transfer

Options granted under the 2017 Plan shall not be transferable in any manner other than as provided in the 2017 Plan. More particularly, the Option may not be assigned, transferred (except as expressly provided in the 2017 Plan), pledged or hypothecated in any way, shall not be assignable by operation of law and shall not be subject to execution, attachment or similar process. Any attempted assignment, transfer, pledge, hypothecation or other disposition of the Option contrary to the provisions of the 2017 Plan, or the levy of any execution,

attachment or similar process upon the Option, shall be null and void and without effect.

Modification of the 2017 Plan

The Administrator may suspend, terminate, modify or amend the 2017 Plan, provided that any amendment that would (i) increase the number of shares reserved for Stock Awards under the Plan, except for certain adjustments upon changes in common stock, (ii) modify the requirements as to eligibility for participation in the 2017 Plan, or (iii) modify the 2017 Plan in any other way if such modification requires stockholder approval in order for the 2017 Plan to satisfy the requirements of Section 422 of the Code, will be subject to the approval of the Company's stockholders. If the 2017 Plan is terminated, the terms of the 2017 Plan will, notwithstanding such termination, continue to apply to outstanding awards granted prior to such termination. Stockholders should be aware that approval of the Plan Amendment will increase the number of shares available for issuance under the 2017 Plan, which may have a dilutive effect on existing stockholders.

New Plan Benefits

At the present time, no specific determination has been made as to the grant or allocation of future awards under the 2017 Plan. Awards granted under the 2017 Plan are within the compensation committee’s discretion, and the compensation committee has not determined future awards or who might receive them. Therefore, at this time, the benefits that will be awarded or paid under the 2017 Plan, if stockholder approval of the Plan Amendment is obtained, cannot currently be determined. The 2017 Plan does not have set benefits or amounts, and no grants or awards have been made by the compensation committee or the board that are conditioned upon stockholder approval of the 2017 Plan.

For illustrative purposes, the following table shows the number of awards granted under the 2017 Plan in fiscal 2025 to each named executive officer, all current executive officers as a group, all current non-employee directors as a group and all employees, including all current officers who are not executive officers, as a group:


	Restricted Stock Units
	Dollar Value ($) (1)		Number of Units (2)
Mike Knowles	$	588,699		152,448
Dan Gabel		289,413		71,284
Jim Ison		179,773		44,279
All Current Executive Officers as a Group	$	1,057,885		268,011

All Current Non-Employee Directors as a Group	$	220,080		84,000

All Employees Other Than Current Executive Officers, as a Group	$	1,433,055		330,738

(1) This column represents restricted stock units awarded in fiscal 2025. The amounts represent the aggregate grant date fair value of the awards computed in accordance with stock-based accounting rules (Financial Accounting Standards Board ("FASB") ASC Topic 718), consistent with the valuation approach described in Footnote 1 to the Summary Compensation Table for fiscal year 2025.

(2) This column corresponds to the number of restricted stock units granted in fiscal 2025.

Effective Date

The Plan Amendment will be effective as of May 13, 2026, subject to stockholder approval at the Annual Meeting.

Registration with the SEC

If the Plan Amendment is approved by our stockholders, the Company intends to file a registration statement on Form S-8, relating to the additional shares of our common stock that will be issuable under the 2017 Plan, with the SEC pursuant to the Securities Act of 1933, as amended, as soon as practicable after approval of the Plan Amendment by our stockholders.

Vote Required

The affirmative vote of the holders of a majority in voting power of the votes cast affirmatively or negatively (excluding absentions) at the Annual Meeting by the holders entitled to vote thereon is required to approve the Plan Amendment. Abstentions and broker non-votes will be counted only for purposes of determining whether a quorum is present. Abstentions will not be considered in tallying votes with respect to this Proposal, and will have no effect on the outcome of the voting results for this Proposal 3. We believe that the approval of Proposal 3 is a nonroutine proposal on which a broker or other nominee does not have discretionary authority to vote. Accordingly, broker non-votes received in connection with this Proposal will not be considered in tallying votes with respect to this Proposal 3, and will have no effect on the outcome of the voting results for this Proposal 3.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF THE PLAN AMENDMENT IN THIS PROPOSAL 3.

PROPOSAL 4:

Advisory Vote to Approve Named Executive Officer Compensation

In accordance with the requirements of Section 14A of the Securities Exchange Act of 1934 (which was added by the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and the related rules of the SEC), the Company is providing its stockholders the opportunity to cast a non-binding, advisory vote on the compensation of its named executive officers. This proposal, commonly known as a “say-on-pay” proposal, gives the Company’s stockholders the opportunity to express their views on the compensation of our named executive officers.

The Company’s named executive officer compensation program is designed to attract, reward and retain the caliber of officers needed to ensure the Company’s continued growth and profitability. This vote is not intended to address any specific item of compensation or any specific named executive officer, but rather the overall compensation of all of our named executive officers described in this proxy statement. The compensation of our named executive officers is disclosed in the section of this proxy statement titled “Executive Compensation,” the compensation tables, and the related narrative disclosure contained therein. We believe that our named executive officer compensation program is competitive within our industry and strongly aligned with the long-term interests of our stockholders. Our compensation committee regularly reviews our named executive officer compensation program and conducts outreach and market assessment to ensure that it achieves the desired goals of aligning our named executive officer compensation structure with our stockholders’ interests and current market practices.

For these reasons, the board of directors recommends a vote in favor of the following resolution:

“RESOLVED, that the stockholders of One Stop Systems, Inc. (the “Company”) approve, on a non-binding advisory basis, compensation paid to the Company’s named executive officers, as disclosed in Part III of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 and its proxy statement for the Annual Meeting, pursuant to the compensation disclosure rules of the SEC, including the compensation tables and narrative discussion.”

Vote Required

As an advisory vote, this Proposal is not binding upon the Company, our board of directors or our compensation committee. Notwithstanding the advisory nature of this vote, our board of directors and the compensation committee value the opinions expressed by stockholders in their vote on this Proposal, and will consider the outcome of the vote when making future compensation decisions for named executive officers.

The affirmative vote of the holders of a majority of the votes cast at the Annual Meeting by the holders entitled to vote thereon is required to approve this Proposal 4. Abstentions and broker non-votes will be counted only for purposes of determining whether a quorum is present. Abstentions will not be considered in tallying votes with respect to this Proposal, and will have no effect on the outcome of the voting results for this Proposal 4. We believe that the approval of Proposal 4 is a nonroutine proposal on which a broker or other nominee does not have discretionary authority to vote. Accordingly, broker non-votes received in connection with this Proposal will not be considered in tallying votes with respect to this Proposal 4, and will have no effect on the outcome of the voting results for this Proposal 4.

RECOMMENDATION OF THE BOARD OF DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF THE ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION IN THIS PROPOSAL 4.

PROPOSAL 5:

Adjournment of the Annual Meeting

General

Our stockholders may be asked to consider and act upon one or more adjournments of the Annual Meeting, if necessary or appropriate, to solicit additional proxies in favor of any of the proposals set forth in this Proxy Statement.

If a quorum is not present at the Annual Meeting, our stockholders may be asked to vote on this proposal to adjourn the Annual Meeting to solicit additional proxies. If a quorum is present at the Annual Meeting, our stockholders may be asked to vote on this proposal to adjourn the Annual Meeting to solicit additional proxies. If a quorum is present at the Annual Meeting, but there are not sufficient votes at the time of the Annual Meeting to approve any of the foregoing proposals, our stockholders may also be asked to vote on this proposal to approve the adjournment of the Annual Meeting to permit further solicitation of proxies in favor of any of the proposals.

If the adjournment proposal is submitted for a vote at the Annual Meeting, and if our stockholders vote to approve the adjournment proposal, the Annual Meeting may be adjourned to another place, or a later date or dates, to enable us to solicit additional proxies in favor of any of the proposals. If the adjournment proposal is approved, and the Annual Meeting is adjourned, we will use the additional time to solicit additional proxies in favor of the relevant proposals to be presented at the Annual Meeting, including the solicitation of proxies from stockholders that have previously voted against any of the proposals.

Our board or directors believes that, if the number of shares of our common stock voting in favor of any of the proposals at the Annual Meeting is insufficient to approve such proposals, it is in the best interests of our stockholders to enable us, if we so choose and for a limited period of time, to continue to seek to obtain a sufficient number of additional votes in favor of such proposals. Any signed proxies received by us in which no voting instructions are provided on such matter will be voted in favor of an adjournment in these circumstances. If the Annual Meeting is adjourned, the time and place of the adjourned Annual Meeting will be announced at the time the adjournment is taken. Any adjournment of the Annual Meeting for the purpose of soliciting additional proxies will allow our stockholders who have already sent in their proxies to revoke them at any time prior to their use at the Annual Meeting, as adjourned or postponed.

Vote Required

The affirmative vote of the holders of a majority of the votes cast at the Annual Meeting by the holders entitled to vote thereon is required to approve this Proposal 5. Abstentions and broker non-votes will be counted only for purposes of determining whether a quorum is present. Abstentions will not be considered in tallying votes with respect to this Proposal, and will have no effect on the outcome of the voting results for this Proposal 5. We believe that the approval of Proposal 5 is a nonroutine proposal on which a broker or other nominee does not have discretionary authority to vote.

BOARD MATTERS AND CORPORATE GOVERNANCE

Board Composition and Election of Directors

Director Independence

Our board of directors has determined that, of our current directors, Mitchell Herbets, Greg Matz, Mike Dumont, and David Basset are all independent directors in accordance with the listing requirements of The Nasdaq Capital Market. The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees, and that neither the director nor any of his or her family members have engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our board of directors has made a subjective determination as to each independent director that no relationships exist, which, in the opinion of our board of directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our board of directors reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directors or executive officers.

Board Committees

Our board of directors has established three standing committees – audit and risk, compensation, and nominating and corporate governance – each of which operates under a charter that has been approved by our board of directors.

The following table provides information for the current membership for each of the committees of our board of directors:

All members of our audit and risk committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and The Nasdaq Capital Market. Our board of directors has determined that Mr. Matz qualifies as an “audit committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable Nasdaq rules and regulations. Our board of directors has determined that Mr. Matz, Mr. Herbets, Mr. Dumont, and Mr. Bassett are independent under the applicable rules of the SEC and The Nasdaq Capital Market.

We believe we are currently in compliance with Nasdaq rules and Rule 10A-3 since all members of our audit and risk committee have been deemed independent by our board of directors. The audit and risk committee operates under a written charter that satisfies the applicable standards of the SEC and The Nasdaq Capital Market.

Report of the Audit and Risk Committee of the Board of Directors

The audit and risk committee oversees the Company’s financial reporting process on behalf of our board of directors. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls. In fulfilling its oversight responsibilities, the audit and risk committee reviewed the audited financial statements in the Company’s annual report with management, including a discussion of any significant changes in the selection or application of accounting principles, the reasonableness of significant judgments, the clarity of disclosures in the financial statements and the effect of any new accounting pronouncements.

The audit and risk committee held six meetings during the 2025 fiscal year, including regular meetings in conjunction with the close of each fiscal quarter, during which the committee reviewed and discussed the Company’s financial statements with management and our independent registered public accounting firm. These audit and risk committee meetings routinely include executive sessions of the committee, as well as private sessions with each of our independent registered public accounting firm and management.

The audit and risk committee reviewed with Haskell & White LLP, which is responsible for expressing an opinion on the conformity of the Company’s audited financial statements with generally accepted accounting principles, its judgments as to the quality, not just the acceptability, of the Company’s accounting principles and such other matters as are required to be discussed with the audit and risk committee under generally accepted auditing standards and the matters listed in Public Company Accounting Oversight Board Auditing Standard No. 1301, Communications with Audit Committees. In addition, the audit and risk committee has discussed with Haskell & White LLP its independence from management and the Company has received written disclosures and the letter required by applicable Public Company Accounting Oversight Board requirements regarding the firm's independence, and has considered whether the provision of non-audit services is compatible with maintaining the auditor's independence.

The audit and risk committee met with Haskell & White LLP to discuss the overall scope of its services, the results of its audit and reviews, and the overall quality of the Company’s financial reporting. Haskell & White LLP, as the Company’s independent registered public accounting firm, also periodically updates the audit and risk committee about new accounting developments and their potential impact on the Company’s reporting. The audit and risk committee’s meetings with Haskell & White LLP were held with and without management present. The audit and risk committee is not employed by the Company, nor does it provide any expert assurance or professional certification regarding the Company’s financial statements. The audit and risk committee relies, without independent verification, on the accuracy and integrity of the information provided, and representations made, by management and the Company’s independent registered public accounting firm.

In reliance on the reviews and discussions referred to above, the audit and risk committee has recommended to the Company’s board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2025 (the “Annual Report”). The audit and risk committee and the Company’s board of directors also have recommended, subject to stockholder approval, the ratification of the appointment of Haskell & White LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026.

This report of the audit and risk committee is not “soliciting material,” shall not be deemed “filed” with the SEC and shall not be incorporated by reference by any general statement incorporating by reference this proxy statement into any filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under such acts.

The foregoing report has been furnished by the audit and risk committee.


	Respectfully submitted,

	The Audit and Risk Committee of the Board of Directors

Compensation Committee

Our compensation committee approves, or recommends to our board of directors, policies relating to compensation and benefits of our officers and employees. The compensation committee approves, or recommends to our board of directors, annual and long-term corporate goals and objectives relevant to the compensation of our chief executive officer and other executive officers, evaluates the performance of these officers in light of those goals and objectives and approves, or recommends to our board of directors, the compensation of these officers based on such evaluations. The compensation committee also approves, or recommends to our board of directors, the issuance of stock options and other awards under our equity incentive plans. The compensation committee will review and evaluate, at least annually, the performance of the compensation committee and its members, including compliance by the compensation committee with its charter.

The members of our compensation committee are Mr. Herbets, Mr. Matz, Mr. Dumont, and Mr. Bassett. Mr. Herbets serves as the chair of the committee. Our board of directors has determined that Mr. Herbets, Mr. Matz, Mr. Dumont, and Mr. Bassett are all independent under the applicable rules and regulations of The Nasdaq Capital Market and all current members qualify as a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act. Our board of directors has determined that each of the members of our compensation committee is an “outside director,” as that term is defined in Section 162(m) of the U.S. Internal Revenue Code of 1986, as amended, or Section 162(m). We are currently in compliance with Nasdaq rules since all members of our compensation committee have been deemed independent by our board of directors. The compensation committee operates under a written charter, which the compensation committee will review and evaluate at least annually. None of the members of the compensation committee is or has been an officer or employee of the Company. None of our executive officers currently serves, or has served during the last fiscal year, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors or compensation committee.

Nominating and Corporate Governance Committee

The nominating and corporate governance committee is responsible for assisting our board of directors in discharging the board of directors’ responsibilities regarding the identification of qualified candidates to become board members, the selection of nominees for election as directors at our annual meetings of stockholders (or

special meetings of stockholders at which directors are to be elected), and the selection of candidates to fill any vacancies on our board of directors and any committees thereof. In addition, the nominating and corporate governance committee is responsible for overseeing our corporate governance policies, reporting and making recommendations to our board of directors concerning governance matters, and oversight of the evaluation of our board of directors.

The members of our nominating and corporate governance committee are Mr. Dumont, Mr. Herbets, Mr. Matz, and Mr. Bassett. Mr. Dumont serves as the chair of the committee. Our board of directors has determined that Mr. Dumont, Mr. Herbets, Mr. Matz, and Mr. Bassett are all independent under the applicable rules and regulations of The Nasdaq Capital Market relating to nominating and corporate governance committee independence. We are currently in compliance with Nasdaq rules due to the fact that all members of our nominating and corporate governance committee have been deemed independent by our board of directors. The nominating and corporate governance committee operates under a written charter, which the nominating and corporate governance committee will review and evaluate at least annually.

Board Leadership Structure

Our board of directors currently consists of five directors. Although our chief executive officer serves as a director on our board, our current chief executive officer and chairman roles are held by two different individuals. Our board of directors will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate to ensure the interests of the Company and its stockholders are best served.

Role of Board in Risk Oversight Process

Our board of directors has responsibility for the oversight of the Company’s risk management processes and, either as a whole or through its committees, regularly discusses with management our major risk exposures, their potential impact on our business and the steps we take to manage them. The risk oversight process includes receiving regular reports from board committees and members of senior management to enable our board of directors to understand the Company’s risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, cybersecurity, use of artificial intelligence, strategic, and reputational risk, as well as risks related to compliance with U.S. Government and Department of Defense contracting requirements, where applicable.

The audit and risk committee reviews information regarding liquidity and operations, and oversees our management of cybersecurity and financial risks. Periodically, the audit and risk committee reviews our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance. Oversight by the audit and risk committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. In addition, the audit and risk committee, among other things, assists our board of directors in overseeing and monitoring the Company’s senior management with carrying out its responsibilities such as identifying and assessing the material risks the company faces, establishing a risk management, crisis management and emergency response plan, overseeing financial, strategic and market risks as well as other risks the Company may face and approving the Company’s enterprise wide risk management framework in conjunction with the board of directors.

The compensation committee is responsible for assessing whether any of our compensation policies or programs have the potential to encourage excessive risk-taking. The nominations and corporate governance committee reviews compliance with external and internal compliance with policies, procedures, and practices consistent with the Company’s amended and restated certificate of incorporation and Bylaws, as amended. While each committee is responsible for evaluating certain risks and overseeing the management of

such risks, the entire board of directors is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by our board of directors as a whole.

Board of Directors Meetings

During fiscal year 2025, our board of directors formally met 11 times, including via telephonic meetings, and held various informal meetings throughout the year. In that year, each director attended at least 75% of the total number of meetings held during such director’s term of service by the board of directors and each committee of the board of directors on which such director served.

Board Composition

Our nominating and corporate governance committee is responsible for reviewing with the board of directors, on an annual basis, the appropriate characteristics, skills, and experience required for the board of directors as a whole and its individual members. In evaluating the suitability of individual candidates (both new candidates and current members), the nominating and corporate governance committee, in recommending candidates for election, and the board of directors, in approving (and, in the case of vacancies, appointing) such candidates, will consider many factors, including the following:

•

personal and professional integrity, ethics and values;

•

experience in corporate management, such as serving as an officer or former officer of a publicly-held company;

•

experience as a board member or executive officer of another publicly-held company;

•

experience with the military, service in the military or experience in the defense contracting industry;

•

strong finance experience;

•

diversity of expertise and experience in substantive matters pertaining to our business relative to other board members;

•

experience relevant to our business industry and with relevant social policy concerns; and

•

relevant academic expertise or other proficiency in an area of our business operations.

Our board of directors evaluates each individual in the context of the board of directors as a whole, with the objective of assembling a group that can best maximize the success of the business and represent stockholder interests through the exercise of sound judgment using its diversity of experience in these various areas.

Communications with our Board of Directors

Stockholders seeking to communicate with our board of directors should submit their written comments to our corporate secretary, One Stop Systems, Inc., 2235 Enterprise Street #110, Escondido, CA 92029. The corporate secretary will forward such communications to the chairman and other members of our board of directors, as relevant; provided that, if in the opinion of our corporate secretary it would be inappropriate to send a particular stockholder communication to a specific director, such communication will only be sent to the remaining relevant directors (subject to the remaining directors concurring with such opinion) or specific committees of the board of directors, as applicable.

Although we do not have a formal policy, members of the board of directors are encouraged to attend annual meetings of our stockholders. A majority of our directors attended the annual meeting of stockholders held in May 2025.

Corporate Governance

Our Code of Business Conduct and Ethics, Corporate Governance Guidelines, Insider Trading Policy, Related Party Transactions Policy, Whistleblower Policy, Audit and Risk Committee Charter, Compensation Committee Charter, and Nominations and Corporate Governance Committee Charter are available, free of

charge, on our website at https://onestopsystems.com/pages/governance-documents. Please note, however, that the information contained on our website is not incorporated by reference in, or considered part of, this proxy statement. We will also provide a copy of these documents as well as our other corporate governance documents, free of charge, to any stockholder upon written request to One Stop Systems, Inc., 2235 Enterprise Street #110, Escondido, CA 92029.

Over the past two years, our Board has implemented a number of meaningful changes with focus on continuous improvement to enhance corporate governance. The changes we implemented were based on outreach, engagement with shareholders, and analysis of best practices and peer companies.

Through updates to Sections 3.3 and 3.4 of our Bylaws, we implemented a majority voting system such that Board nominees with the highest number of “for” votes will be elected to the Board. Nominees that are currently serving on the Board that receive a greater number of votes “against” than votes “for” must promptly tender their resignation. Following receipt of such resignation the Nominations and Corporate Governance Committee will consider the resignation and recommend to the Board of Directors whether to accept such tendered resignation. Except in special circumstances, the Nominations Committee will be expected to accept and recommend acceptance to the Board, and the Board will be expected to accept such recommendation.

The Nominating and Governance Committee and Board also reviewed inputs relative to the Supermajority requirement. After detailed outreach, assessment, and discussion, the Board determined that it was in the best interest of the Company to retain the Supermajority requirement. This was consistent with similar peer company practices and, when taken in concert with the adoption of majority voting as described above, allows shareholders to have say on the construction of the Board.

We updated our Insider Trading Policy to include an Anti-Pledging and Anti-Hedging policy. Our Insider Trading Policy governing the purchase, sale and/or other disposition of the Company's securities by directors, officers, and employees, or the registrant itself, is designed to promote compliance with insider trading laws, rules, and regulations. It is our policy to comply with all applicable securities laws when transacting in securities. We have incorporated an anti-pledging policy with no pre-clearance to prohibit use of company stock as collateral to secure loans. We also incorporated an anti-hedging policy to prohibit engaging in financial transactions that would offset potential declines in the value of company stock holdings.

The Company operates in sectors that require compliance with applicable U.S. Department of Defense (“DoD”) regulations and contracting requirements. The Board of Directors, primarily through the audit and risk committee, oversees management’s processes for identifying and managing risks related to compliance with such requirements, including, as applicable, cybersecurity, data protection, export controls, and government contracting obligations. Management maintains policies and procedures designed to support compliance with applicable laws, regulations, and contractual requirements, and periodically reports to the Board regarding these matters.

Conflicts of Interest

Our directors and officers are not obligated to commit their full time and attention to our business and, accordingly, they may encounter a conflict of interest in allocating their time between our operations and those of other businesses. In the course of their other business activities, they may become aware of investment and business opportunities which may be appropriate for presentation to us as well as other entities to which they owe a fiduciary duty. As a result, they may have conflicts of interest in determining to which entity a particular business opportunity should be presented. They may also in the future become affiliated with entities that are engaged in business activities similar to those we intend to conduct.

In general, officers and directors of a corporation are required to present business opportunities to the corporation if:

•

the corporation could financially undertake the opportunity;

•

the opportunity is within the corporation’s line of business; and

•

it would be unfair to the corporation and its stockholders not to bring the opportunity to the attention of the corporation.

We have adopted a Code of Business Conduct and Ethics that obligates our directors, officers, and employees to disclose potential conflicts of interest and prohibits those persons from engaging in such transactions without our consent.
