INFORMATION ABOUT THIS PROXY STATEMENT

Why you received this proxy statement. You are viewing or have received these proxy materials because Ouster’s Board is soliciting your proxy to vote your shares at the Annual Meeting. This proxy statement includes information that we are required to provide to you under the rules of the Securities and Exchange Commission (the “SEC”) and that is designed to assist you in voting your shares.

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, Ouster is making this proxy statement and its 2025 Annual Report available to its stockholders electronically via the Internet. On or about April [•], 2026, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this proxy statement and our 2025 Annual Report and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in this proxy statement and 2025 Annual Report. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained in the Internet Notice.

TABLE OF CONTENTS

Printed Copies of Our Proxy Materials. If you received printed copies of our proxy materials, then instructions regarding how you can vote are contained on the proxy card included in the materials.

Householding. The SEC’s rules permit us and intermediaries (such as brokers, banks and other agents) to deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we and a number of intermediaries with account holders who are our stockholders have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. A proxy card or voting instruction form will be delivered for each of the stockholders sharing an address. We agree to deliver promptly, upon written or oral request, a separate set of proxy materials, as requested, to any stockholder at the shared address to which a single set of those documents was delivered. If you prefer to receive separate copies of the proxy materials, contact Broadridge Financial Solutions, Inc. at (866) 540-7095 or in writing at Broadridge Financial Solutions, Inc., Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

If you are currently a stockholder sharing an address with another stockholder and wish to receive only one set of future proxy materials for your household, please contact Broadridge at the above phone number or address.

TABLE OF CONTENTS

QUESTIONS AND ANSWERS ABOUT THE 2026 ANNUAL MEETING OF STOCKHOLDERS

WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?

The Record Date for the Annual Meeting is April 24, 2026. You are entitled to vote at the Annual Meeting only if you were a stockholder of record at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. You will need to obtain your own Internet access if you choose to attend the Annual Meeting and/or vote over the Internet. Each share of our common stock entitles its holders to one vote per share on all matters presented to our stockholders at the Annual Meeting. At the close of business on the Record Date, there were [•] shares of common stock issued and outstanding and entitled to vote at the Annual Meeting.

WHAT IS THE DIFFERENCE BETWEEN BEING A “RECORD HOLDER” AND HOLDING SHARES IN “STREET NAME”?

A record holder holds shares in his or her name. Shares held in “street name” are held in the name of a bank, broker or other agent on a person’s behalf.

AM I ENTITLED TO VOTE IF MY SHARES ARE HELD IN “STREET NAME”?

Yes. If your shares are held by a bank, broker or other agent, you are considered the “beneficial owner” of those shares held in “street name.” If your shares are held in “street name,” our proxy materials are being provided to you by your bank, broker or other agent, along with a voting instruction card if you received printed copies of our proxy materials. As the beneficial owner, you have the right to direct your bank, broker or other agent how to vote your shares, and the bank, broker or other agent is required to vote your shares in accordance with your instructions.

If your shares are held in “street name” and you have not received a 16-digit control number, you should contact your bank or broker to obtain your control number or otherwise vote through the bank or broker. If you would like to vote your shares online during the Annual Meeting, your bank or broker will need to provide you with a 16-digit control number.

HOW MANY SHARES MUST BE PRESENT TO HOLD THE ANNUAL MEETING?

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, represented by remote communication or represented by proxy, of the holders of one third (1/3) in voting power of common stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum.

WHAT IF A QUORUM IS NOT PRESENT AT THE ANNUAL MEETING?

If a quorum is not present at the scheduled time of the Annual Meeting, then either (i) the person presiding over the Annual Meeting or (ii) a majority in voting power of the stockholders entitled to vote at the Annual Meeting, present by remote communication or represented by proxy, may adjourn the Annual Meeting until a quorum is present or represented.

WHO CAN ATTEND AND VOTE AT THE 2026 ANNUAL MEETING OF STOCKHOLDERS?

You may attend and vote at the Annual Meeting only if you are an Ouster stockholder who is entitled to vote at the Annual Meeting, or if you hold a valid proxy for the Annual Meeting. The Annual Meeting will be held entirely online to allow greater participation. You will be able to attend the Annual Meeting and submit your questions by visiting the following website: www.virtualshareholdermeeting.com/OUST2026. You will also be able to vote your shares electronically at the Annual Meeting.

To participate in the Annual Meeting, you will need the 16-digit control number included in your Internet Notice, on your proxy card or on the instructions that accompanied your proxy materials. The Annual Meeting webcast will begin promptly at 10:00 a.m., Pacific Time. We encourage you to access the Annual Meeting prior to the start time. Online check-in will begin at 9:45 a.m., Pacific Time, and you should allow ample time for check-in procedures. If

TABLE OF CONTENTS

you hold your shares through a bank or broker, instructions should also be provided on the voting instruction card provided by your bank or brokerage firm. If you lose your 16-digit control number, you may join the Annual Meeting as a “Guest,” but you will not be able to vote or ask questions.

WHY IS THE MEETING HELD VIRTUALLY?

We believe that hosting a virtual meeting is in the best interests of the Company and our stockholders. A virtual meeting enables increased stockholder attendance and participation because stockholders can participate from any location around the world. A virtual meeting can also provide cost savings for our stockholders and us, and it is more environmentally friendly.

WHAT IF DURING THE CHECK-IN TIME OR DURING THE ANNUAL MEETING I HAVE TECHNICAL DIFFICULTIES OR TROUBLE ACCESSING THE VIRTUAL MEETING WEBSITE?

We will have technicians ready to assist you with any technical difficulties you may have when accessing the Annual Meeting website. If you encounter any difficulties accessing the Annual Meeting, please call the technical support number that will be posted on the Annual Meeting login page.

WHAT DOES IT MEAN IF I RECEIVE MORE THAN ONE INTERNET NOTICE OR MORE THAN ONE SET OF PROXY MATERIALS?

It means that your shares are held in more than one account at the transfer agent and/or with banks or brokers. Please vote all of your shares. To ensure that all of your shares are voted, for each Internet Notice or set of proxy materials, please submit your proxy by phone, via the Internet, or, if you received printed copies of the proxy materials, by signing, dating and returning the enclosed proxy card in the enclosed envelope.

HOW DO I VOTE?

We recommend that stockholders vote by proxy even if they plan to participate in the Annual Meeting. If you are a stockholder of record, you may vote by proxy:

•	by Internet—You can vote over the Internet at www.proxyvote.com by following the instructions on the Internet Notice or proxy card;

•	by Telephone—You can vote by telephone by calling (800) 690-6903 and following the instructions on the proxy card; or

•	by Mail—You can vote by mail by signing, dating and mailing the proxy card, which you may have received by mail.

Internet and telephone voting facilities for stockholders of record will be available 24 hours a day and will close at 8:59 p.m., Pacific Time, on June 16, 2026.

To participate in the Annual Meeting, including to vote via the Internet during the Annual Meeting, you will need to visit www.virtualshareholdermeeting.com/OUST2026 and enter the 16-digit control number included on your Internet Notice, proxy card or the instructions that accompanied your proxy materials. The Annual Meeting webcast will begin promptly at 10:00 a.m., Pacific Time, on June 17, 2026.

If your shares are held in “street name” through a bank, broker or other nominee, you will receive instructions on how to vote from the bank or brokerage firm. You must follow their instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you would like to vote your shares at the Annual Meeting, you may visit www.virtualshareholdermeeting.com/OUST2026 and enter the 16-digit control number included in the voting instruction card provided to you by your bank or brokerage firm. If you hold your shares in “street name” and you do not receive a 16-digit control number, you may need to log in to your bank or brokerage firm’s website and select the shareholder communications mailbox to access the Annual Meeting and vote. Instructions should also be provided on the voting instruction card provided by your bank or brokerage firm.

TABLE OF CONTENTS

CAN I CHANGE MY VOTE AFTER I SUBMIT MY PROXY?

Yes. If you are a stockholder of record, you may revoke your proxy and change your vote:

•	by submitting a duly executed proxy bearing a later date;

•	by granting a subsequent proxy through the Internet at www.proxyvote.com or telephone by calling (800) 690-6903;

•	by giving timely written notice of revocation to our Secretary prior to the Annual Meeting by writing to Ouster’s offices at 350 Treat Avenue, San Francisco, California 94110; or

•	by voting during the Annual Meeting.

Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your virtual attendance at the Annual Meeting by itself will not revoke your proxy.

If you are a beneficial holder of shares or if your shares are held in “street name,” you may change or revoke your voting instructions by following the specific directions provided to you by your bank, broker or other agent, or you may vote electronically during the Annual Meeting using your 16-digit control number.

WHO WILL COUNT THE VOTES?

A representative of Broadridge Financial Solutions, Inc., our inspector of election, will tabulate and certify the votes.

WHAT IF I DO NOT SPECIFY HOW MY SHARES ARE TO BE VOTED?

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies on the Company’s proxy card will vote in accordance with the recommendations of the Board. The Board’s recommendations are indicated on page 2 of this proxy statement, as well as with the description of each proposal in this proxy statement.

WILL ANY OTHER BUSINESS BE CONDUCTED AT THE ANNUAL MEETING?

We know of no business other than those matters listed in the Notice of Meeting at the beginning of this proxy statement that will be presented at the Annual Meeting. If any other matter properly comes before the stockholders for a vote at the Annual Meeting; however, the proxy holders named on the Company’s proxy card will vote your shares in accordance with their best judgment.

HOW MANY VOTES ARE REQUIRED FOR THE APPROVAL OF THE PROPOSALS TO BE VOTED UPON AND HOW WILL ABSTENTIONS AND BROKER NON-VOTES BE TREATED?


Proposal	Votes required	Effect of Votes Withheld /Abstentions and Broker Non-Votes
Proposal 1: Election of Directors	The plurality of the votes cast. This means that the two nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II Directors.	Votes withheld and broker non-votes will have no effect.

Proposal 2: Ratification of Appointment of our Independent Registered Public Accounting Firm	The affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter.	Abstentions and broker non-votes, if any, will have no effect, and because brokers have discretionary authority to vote on this proposal we do not expect any broker non-votes in connection with this proposal.

TABLE OF CONTENTS


Proposal	Votes required	Effect of Votes Withheld /Abstentions and Broker Non-Votes
Proposal 3: Approval, on an Advisory (Non-Binding) Basis, of the Compensation of our Named Executive Officers	The affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes) on such matter.	Abstentions and broker non-votes will have no effect.

Proposal 4: Approval of an amendment to our Certificate of Incorporation to increase the number of authorized shares of the Company’s common stock from 100,000,000 to 200,000,000	The votes cast for the matter exceed the votes cast against such matter.	Abstentions and broker non-votes will have no effect.

Proposal 5: Approval of an amendment to our Certificate of Incorporation to provide for exculpation of officers from breaches of fiduciary duty to the extent permitted by the General Corporation Law of the State of Delaware	The affirmative vote of a majority of the outstanding shares of common stock entitled to vote on such matter.	Abstentions and broker non-votes will have the same effect as votes against the proposal.

WHAT IS AN ABSTENTION AND HOW WILL VOTES WITHHELD AND ABSTENTIONS BE TREATED?

A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the four other proposals to be voted on at the Annual Meeting, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote solely for purposes of determining a quorum. Votes withheld will have no effect on the election of directors and abstentions will have no effect on Proposal Nos. 2, 3 and 4. Abstentions will have the same effect as votes against Proposal No. 5.

WHAT ARE BROKER NON-VOTES AND DO THEY COUNT FOR DETERMINING A QUORUM?

Generally, broker non-votes occur when shares held by a broker, bank or other agent in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker, bank or other agent (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker or other agent is entitled to vote shares held for a beneficial owner on routine matters without instructions from the beneficial owner of those shares. The only routine matters presented at the Annual Meeting are Proposal No. 2, relating to the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the year ending December 31, 2026, and Proposal No. 4, relating to the increase in our authorized shares. On the other hand, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on non-routine matters, such as Proposal Nos. 1, 3 and 5. Broker non-votes count for purposes of determining whether a quorum is present.

WHERE CAN I FIND THE VOTING RESULTS OF THE 2026 ANNUAL MEETING OF STOCKHOLDERS?

We plan to announce preliminary voting results at the Annual Meeting and we will report the final results in a Current Report on Form 8-K, which we intend to file with the SEC within four business days of the Annual Meeting.

TABLE OF CONTENTS

WILL THERE BE A QUESTION-AND-ANSWER SESSION DURING THE ANNUAL MEETING?

As part of the Annual Meeting, we will hold a Q&A session, during which we intend to answer appropriate questions submitted by stockholders during the Annual Meeting or questions submitted at www.proxyvote.com in advance of the Annual Meeting that are pertinent to the Company and the Annual Meeting matters, for up to 10 minutes after the completion of the Annual Meeting. Appropriate questions submitted by stockholders will be read during the Q&A portion of the Annual Meeting. Through this process, we believe we can respond to more questions than we were able to respond to at an in-person meeting. Only stockholders that have accessed the Annual Meeting as a stockholder (rather than a “Guest”) by following the procedures outlined above in “Who can attend and vote at the 2026 Annual Meeting of Stockholders?” will be permitted to submit questions during the Annual Meeting. If you would like to submit questions in advance of the Annual Meeting, please visit www.proxyvote.com before 11:59 p.m. Eastern Time on June 16, 2026 and enter your 16-digit control number. Each stockholder is limited to no more than two questions. Questions should be succinct and only cover a single topic. We will not address questions that are, among other things:

•	irrelevant to the business of the Company or to the business of the Annual Meeting;

•	related to material non-public information of the Company, including the status or results of our business since our last Quarterly Report on Form 10-Q;

•	related to any pending, threatened or ongoing litigation;

•	related to personal grievances;

•	derogatory references to individuals or that are otherwise in bad taste;

•	substantially repetitious of questions already made by another stockholder;

•	in excess of the two-question limit;

•	in furtherance of the stockholder’s personal or business interests; or

•	out of order or not otherwise suitable for the conduct of the Annual Meeting as determined by the Chair or Corporate Secretary in their reasonable judgment.

Depending on the number of questions submitted, we may not be able to answer all questions during the Annual Meeting. Additional information regarding the Q&A session will be available in the “Rules of Conduct” available on the Annual Meeting webpage for stockholders who have accessed the Annual Meeting as a stockholder (rather than a “Guest”) by following the procedures outlined above in “Who can attend and vote at the 2026 Annual Meeting of Stockholders?”.

TABLE OF CONTENTS

PROPOSALS TO BE VOTED ON

PROPOSAL 1: Election of Directors

At the Annual Meeting, two (2) Class II Directors are to be elected to hold office until our annual meeting of stockholders to be held in 2029 and until such director’s successor is duly elected and qualified or until such director’s earlier death, resignation or removal.

We currently have eight (8) directors on our Board. Current director Virginia Boulet has not been nominated for re-election at the Annual Meeting. The proposal regarding the election of directors requires the approval of a plurality of the votes cast. This means that the two nominees receiving the highest number of affirmative “FOR” votes will be elected as Class II Directors. Votes withheld and broker non-votes will have no effect on the outcome of the vote on this proposal.

Our Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting of stockholders following election or such director’s death, resignation or removal, whichever is earliest to occur. The current class structure is as follows: Class II, whose current term will expire at the upcoming Annual Meeting and whose subsequent term will expire at the 2029 annual meeting of stockholders; Class III, whose term will expire at the 2027 annual meeting of stockholders; and Class I, whose term will expire at the 2028 annual meeting of stockholders.

PROPOSAL 2: Ratification of Appointment of Independent Registered Public Accounting Firm

Our Audit Committee of the Board (the “Audit Committee”) has appointed PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of the Audit Committee’s appointment of PricewaterhouseCoopers LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of such appointment is a good corporate governance practice.

PricewaterhouseCoopers LLP also served as our independent registered public accounting firm for the fiscal years ended December 31, 2022 through December 31, 2025. Neither PricewaterhouseCoopers LLP nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of PricewaterhouseCoopers LLP is expected to attend the Annual Meeting, have an opportunity to make a statement if he or she desires to do so, and be available to respond to appropriate questions from stockholders.

In the event that the appointment of PricewaterhouseCoopers LLP is not ratified by the stockholders, the Audit Committee will consider this fact when it appoints the independent auditors for the fiscal year ending December 31, 2027. Even if the appointment of PricewaterhouseCoopers LLP is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interests of Ouster.

RECOMMENDATION OF THE BOARD OF DIRECTORS


			The Board of Directors unanimously recommends a vote “FOR” the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026.

TABLE OF CONTENTS

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee has reviewed the Company’s audited financial statements for the fiscal year ended December 31, 2025 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm the matters that they are required to provide to the Audit Committee, including the matters required to be discussed by the Public Company Accounting Oversight Board (“PCAOB”) and the SEC.

The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by the applicable requirements of the PCAOB describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company.

The Audit Committee has been actively engaged in overseeing the material weaknesses that the Company identified in its Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and in subsequent Form 10-Ks (“Material Weaknesses”). The Company remediated aspects of the Material Weaknesses in each of the fiscal years ended December 31, 2022, December 31, 2023, and December 31, 2024. In fiscal year ended December 31, 2025, the Company remediated all remaining aspects of the Material Weaknesses.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025.

The Audit Committee Report does not constitute soliciting material, and shall not be deemed to be filed or incorporated by reference into any other filing under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent that the Company specifically incorporates the Audit Committee Report by reference therein.

TABLE OF CONTENTS

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES AND OTHER MATTERS

Set forth below are the fees paid to our independent registered public accounting firm, PricewaterhouseCoopers LLP, for the fiscal years ended December 31, 2025 and 2024:


Fee Category	Fiscal 2025	Fiscal 2024
Audit Fees	$2,754,000	$1,290,344
Audit-Related Fees	—	$300,000
All Other Fees	$2,000	$2,000
Total Fees	$2,756,000	$1,592,344

AUDIT FEES

Audit fees in 2025 and 2024 consisted of fees for the audit of our annual financial statements, the review of the interim financial statements included in our Quarterly Reports on Form 10-Q, the review of financial statements to be included in registration statements, services associated with the issuance of comfort letters and the issuance of consents to registration statements and other professional services provided in connection with statutory and regulatory filings or engagements.

AUDIT-RELATED FEES

Audit-related fees consist of fees that are reasonably related to the performance of the audit and the review of our financial statements and which are not reported under “Audit Fees”.

ALL OTHER FEES

For 2025 and 2024, all other fees consisted of fees related to technical research tools and similar resources.

AUDIT COMMITTEE PRE-APPROVAL POLICY AND PROCEDURES

The Audit Committee has adopted a policy (the “Pre-Approval Policy”) that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent auditor may be pre-approved. The Pre-Approval Policy generally provides that we will not engage PricewaterhouseCoopers LLP to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the Audit Committee (“specific pre-approval”) or (ii) entered into pursuant to the pre-approval policies and procedures described in the Pre-Approval Policy (“general pre-approval”). Unless a type of service to be provided by PricewaterhouseCoopers LLP has received general pre-approval under the Pre-Approval Policy, it requires specific pre-approval by the Audit Committee or by a designated member of the Audit Committee to whom the committee has delegated the authority to grant pre-approvals. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval. For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. The Audit Committee periodically reviews and generally pre-approves any services (and related fee levels or budgeted amounts) that may be provided by PricewaterhouseCoopers LLP without first obtaining specific pre-approvals from the Audit Committee or the Chair of the Audit Committee. The Audit Committee may revise the list of general pre-approved services from time to time, based on subsequent determinations.

PROPOSAL 3: Approval, on an Advisory (Non-Binding) Basis, of the Compensation of Our Named Executive Officers

In accordance with the Dodd–Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) and Rule 14a-21(a) under the Securities Exchange Act of 1934, as amended, we request that our stockholders cast a non-binding, advisory vote to approve the compensation of our named executive officers identified in the section titled “Executive Compensation” set forth below in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement.

Accordingly, we ask our stockholders to vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that the Company’s stockholders hereby approve, on an advisory (non-binding) basis, the compensation of the Company’s named executive officers, as disclosed in the Company’s proxy statement for the 2026 annual meeting of stockholders pursuant to Item 402 of Regulation S-K, including the compensation tables and narrative discussion.”

We believe that our compensation programs and policies for the year ended December 31, 2025 were an effective incentive for the achievement of our goals, aligned with stockholders’ interest and are worthy of stockholder support. Additional details concerning how we structure our compensation programs to meet the objectives of our compensation program are provided in the section titled “Executive Compensation” set forth below in this proxy statement. In particular, we discuss how we design our performance-based compensation programs and set compensation targets and other objectives to maintain a close correlation between Company achievement and individual compensation.

This vote is merely advisory and will not be binding upon the Company, our Board or the Board’s Compensation Committee (the “Compensation Committee”), nor will it create or imply any change in the duties of the Company, our Board or the Compensation Committee. The Compensation Committee will, however, take into account the outcome of the vote when considering future executive compensation decisions. At our 2025 annual meeting of stockholders, approximately 94.1% of the votes cast were voted “for” the proposal. The Board values constructive dialogue on executive compensation and other significant governance topics with our stockholders and encourages all stockholders to vote their shares on this important matter.

At our annual meeting of stockholders held on June 9, 2022, our stockholders recommended, on an advisory basis, that future stockholder votes on the compensation of our named executive officers occur every year. In light of the foregoing recommendation, our Board determined to hold a “say-on-pay” advisory vote every year. An annual advisory vote on executive compensation is consistent with our policy of seeking regular dialogue with our stockholders on corporate governance matters and our executive compensation philosophy, policies and practices. We understand that our stockholders may have different views as to what is the best approach for the Company, and we look forward to hearing from our stockholders on this proposal. Accordingly, our next advisory say-on-pay vote (following the advisory vote at this Annual Meeting) is expected to occur at our 2027 annual meeting of stockholders.

RECOMMENDATION OF THE BOARD OF DIRECTORS


			The Board of Directors unanimously recommends a vote “FOR” the approval, on an advisory (non-binding) basis, of the compensation of our named executive officers.

PROPOSAL 4: Approval of an Amendment to our Certificate of Incorporation to increase the number of authorized shares of the Company’s common stock from 100,000,000 to 200,000,000

Our Certificate of Incorporation currently authorizes the issuance of 100,000,000 shares of common stock. On February 24, 2026, our Board adopted a resolution to amend the Certificate of Incorporation, subject to stockholder approval, by increasing the number of authorized shares of our common stock to 200,000,000 shares (the “Authorized Shares Amendment”). The additional 100,000,000 shares of common stock authorized for issuance pursuant to the proposed Authorized Shares Amendment would be part of the existing class of common stock and, if and when issued, would have the same rights and privileges as the shares of common stock presently issued and outstanding. The holders of common stock are not entitled to preemptive rights or cumulative voting. The Authorized Shares Amendment will not affect the number of authorized shares of preferred stock of the Company, par value $0.0001 per share, which is 100,000,000 shares. Currently, there are no shares of preferred stock issued and outstanding.

If our stockholders approve this proposal, then Article IV of our Certificate of Incorporation will be deleted and replaced in its entirety to read as follows:

“The Corporation is authorized to issue two classes of stock to be designated, respectively, “Common Stock” and “Preferred Stock.” The total number of shares of capital stock that the Corporation shall have authority to issue is 300,000,000. The total number of shares of Common Stock that the Corporation is authorized to issue is 200,000,000, having a par value of $0.0001 per share, and the total number of shares of Preferred Stock that the Corporation is authorized to issue is 100,000,000, having a par value of $0.0001 per share.”

Purpose of Authorized Shares Amendment

Our Board believes it is in the best interests of the Company and our stockholders to increase our authorized shares of common stock in order to have additional shares available for use as our Board deems appropriate or necessary. As such, the primary purpose of the Authorized Shares Amendment is to provide the Company with greater flexibility with respect to managing its common stock in connection with such corporate purposes as may, from time to time, be considered advisable by our Board. These corporate purposes could include, without limitation, financing activities, public or private offerings of common stock, stock dividends or splits, conversions of convertible securities, issuance of options and other equity awards pursuant to our incentive plans, establishing a strategic relationship with a corporate collaborator and acquisition transactions. Having an increased number of authorized but unissued shares of common stock would allow us to take prompt action with respect to corporate opportunities that develop, without the delay and expense of convening a special meeting of stockholders for the purpose of approving an increase in our capitalization. Our Board will determine whether, when and on what terms the issuance of shares of common stock may be warranted in connection with any of the foregoing purposes.

Effect of Approval of Proposed Amendment

The following table illustrates the effect the proposed Authorized Shares Amendment would have on the number of shares of common stock available for issuance, if approved by our stockholders:


	As of March 31, 2026	Upon Effectiveness of Amendment
TOTAL AUTHORIZED SHARES OF COMMON STOCK	100,000,000	200,000,000
Outstanding shares of common stock	63,461,091	63,461,091
Shares of common stock authorized for future issuance under the Company's incentive plans	4,743,644	4,743,644
Shares of common stock authorized for future issuance under the Company's employee stock purchase plan	1,626,215	1,626,215
Shares of common stock subject to outstanding equity awards under the Company's incentive plans	5,223,464	5,223,464
Shares of common stock issuable upon exercise of outstanding warrants	3,277,155	3,277,155
Shares of common stock reserved for issuance as part of our “at the market” equity offering program	10,713,209	10,713,209

TABLE OF CONTENTS

Other than shares that will be reserved for issuance under our existing incentive plans, employee stock purchase plan, and “at the market” equity offering program, we do not currently have any arrangements, agreements or understandings that would require the issuance of additional shares of common stock. Because our directors and executive officers have outstanding equity awards under our incentive plans, and may be granted additional equity awards under these plans, they may be deemed to have an indirect interest in the Authorized Shares Amendment because, absent the amendment, the Company may not have sufficient authorized shares to make future awards.

The Authorized Shares Amendment will not have any immediate effect on the rights of existing stockholders. However, our Board will have the authority to issue authorized common stock without requiring future stockholder approval of such issuances, except as may be required by applicable law or rules of the Nasdaq Stock Market. Future issuances of common stock or securities convertible into or exchangeable for common stock could have a dilutive effect on our earnings per share, book value per share and the voting power and interest of current stockholders.

If the Authorized Shares Amendment is approved by stockholders, all other sections of the Certificate of Incorporation would be maintained in their current form. The Authorized Shares Amendment would become effective upon the filing of a Certificate of Amendment to our Certificate of Incorporation with the Secretary of State of the State of Delaware, which the Company intends to do promptly after the Annual Meeting if this Proposal is approved by stockholders.

In the event that the Authorized Shares Amendment is not approved by our stockholders at the Annual Meeting, the current Certificate of Incorporation would remain in effect in its entirety. Our Board reserves the right, notwithstanding stockholder approval of the Authorized Shares Amendment and without further action by our stockholders, not to proceed with the Authorized Shares Amendment at any time before it becomes effective.

Potential Anti-Takeover Effect

Our Board has not proposed the Authorized Shares Amendment with the intention of discouraging tender offers or takeover attempts of the Company. However, the availability of additional authorized shares for issuance could, under certain circumstances, discourage or make more difficult efforts to obtain control of our Company. This proposal is not being presented with the intent that it be used to prevent or discourage any acquisition attempt, but nothing would prevent our Board from taking any appropriate actions not inconsistent with its fiduciary duties.

Dissenters' Rights of Appraisal

Under Delaware law, stockholders are not entitled to appraisal rights with respect to the Authorized Shares Amendment, and we will not independently provide our stockholders with any such right.

RECOMMENDATION OF THE BOARD OF DIRECTORS


			The Board of Directors unanimously recommends a vote “FOR” the Authorized Shares Amendment

TABLE OF CONTENTS

PROPOSAL 5: Approval of an Amendment to our Certificate of Incorporation to Provide for Exculpation of Officers from Breaches of Fiduciary Duty to the Extent Permitted by the General Corporation Law of the State of Delaware.

Background

In Proposal 5, the Board seeks the approval of an amendment (the “Exculpation Amendment”) to the Company’s Certificate of Incorporation to provide for the exculpation of officers of the Company from liability for breach of the fiduciary duty of care to the extent permitted by the General Corporation Law of the State of Delaware (“DGCL”). A copy of the Exculpation Amendment contemplated by Proposal 5 is attached hereto as Annex B.

Effective August 1, 2022, Section 102(b)(7) of the DCGL was amended (“Amended 102(b)(7)”) to enable a corporation to include in its certificate of incorporation a provision exculpating certain corporate officers from liability for breach of the fiduciary duty of care in certain circumstances. Previously, Section 102(b)(7) of the DGCL provided for the ability to exculpate directors only, and our Certificate of Incorporation currently limits the monetary liability of our directors in certain circumstances consistent with Section 102(b)(7) of the DGCL. Amended 102(b)(7) allows for the exculpation of certain of our officers only in connection with direct claims brought by stockholders, including class actions, but would not eliminate officers’ monetary liability for breach of fiduciary duty claims brought by the corporation itself or for derivative claims brought by stockholders in the name of the corporation. Further, Amended 102(b)(7) does not permit a corporation to exculpate covered officers from liability for breach of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit. Under Amended 102(b)(7), the officers who may be exculpated include a person who (i) is the president, chief executive officer, chief operating officer, chief financial officer, chief legal officer, controller, treasurer or chief accounting officer of the corporation at any time during the course of conduct alleged in the action or proceeding to be wrongful, (ii) is or was identified in the corporation’s public filings with the SEC because such person is or was one of the most highly compensated executive officers of the corporation, or (iii) has consented to service of process in Delaware by written agreement (collectively, “Covered Officers”). The proposed Exculpation Amendment would allow for the exculpation of our Covered Officers to the fullest extent permitted by the DGCL.

The Board has unanimously adopted and is submitting for stockholder approval the Exculpation Amendment. If our stockholders approve the Exculpation Amendment, our Board has authorized our officers to file a Certificate of Amendment with the Delaware Secretary of State, which we anticipate doing as soon as practicable following stockholder approval of the Exculpation Amendment at the 2026 annual meeting, and the Certificate of Amendment would become effective upon acceptance by the Delaware Secretary of State.

If our stockholders do not approve the Exculpation Amendment, the Company’s current exculpation provisions relating to directors will remain in place, and the Certificate of Amendment will not be filed with the Delaware Secretary of State. However, even if our stockholders approve the Exculpation Amendment, our Board retains discretion under Delaware law to determine when to file the Certificate of Amendment with the Delaware Secretary of State and to abandon the Exculpation Amendment notwithstanding prior stockholder approval of the Exculpation Amendment.

Effect of the Exculpation Amendment

The Exculpation Amendment contemplated by Proposal 5 would allow for the exculpation of Covered Officers to the fullest extent permitted by the DGCL, as is currently in effect or as it may hereafter be amended.

The Exculpation Amendment would currently allow for the exculpation of officers who are Covered Officers only in connection with direct claims brought by stockholders, including class actions, but would not eliminate officers’ monetary liability for breach of fiduciary duty claims brought by the corporation itself or for derivative claims brought by stockholders in the name of the corporation. Further, the Exculpation Amendment would not limit the liability of officers for any breach of the duty of loyalty to the corporation or its stockholders, any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, or any transaction from which the officer derived an improper personal benefit. Our current executive officers may have an interest in the approval of the Exculpation Amendment, as they may be exculpated from liability for certain actions to the extent consistent with the DGCL.

TABLE OF CONTENTS

Reasons for the Exculpation Amendment

Our Board believes that adopting the Exculpation Amendment contemplated by this Proposal 5 would better position the Company to attract top officer candidates and retain our current officers. The Exculpation Amendment would also more closely align the protections available to our officers with those already available to our directors. We believe that failing to adopt the Exculpation Amendment could impact our recruitment and retention of exceptional officer candidates who conclude that the potential exposure to liabilities, costs of defense, and other risks of proceedings exceeds the benefits of serving as an officer of the Company.

In addition, adopting the Exculpation Amendment contemplated by this Proposal 5 would enable the officers to exercise their business judgment in furtherance of the interests of the stockholders without the potential for distraction posed by the risk of personal liability. The nature of the role of officers often requires them to make decisions on crucial matters. Frequently, officers must make decisions in response to time-sensitive opportunities and challenges, which can create substantial risk of investigations, claims, actions, suits, or proceedings seeking to impose liability based on hindsight, especially in the current litigious environment and regardless of merit. Limiting our current and prospective officers’ concern about personal risk would empower officers to best exercise their business judgment in furtherance of stockholder interests and better position the Company to retain our current officers and attract top officer candidates. We believe that enhancing our ability to retain and attract experienced officers is in the best interests of the Company and its stockholders. We also believe that adopting the proposed amendment may lessen the Company’s exposure to potential expense associated with defending our officers against claims that have no legal merit.

RECOMMENDATION OF THE BOARD OF DIRECTORS


			The Board of Directors unanimously recommends a vote “FOR” the approval of the Exculpation Amendment.

CORPORATE GOVERNANCE

GENERAL

Our Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics and charters for the Board’s Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of Ouster. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Business Conduct and Ethics in the “Corporate Governance” section under “Documents & Charters” of our Investors website at investors.ouster.com, or by writing to our Secretary at our offices at 350 Treat Avenue, San Francisco, California 94110.

BOARD COMPOSITION

Our Board currently consists of eight (8) members: Virginia Boulet, Susan Heystee, Ernest Maddock, Angus Pacala, Christina C. Correia, Stephen A. Skaggs, Phillip M. Eyler and Theodore L. Tewksbury, Ph.D. As disclosed above, Virginia Boulet has not been nominated for re-election at the Annual Meeting. Our Board is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting following election or such director’s death, resignation or removal, whichever is earliest to occur. Between annual meetings, the Board may elect directors to fill vacancies with new directors allocated among classes and each class should consist, as nearly as may be possible, of one-third of the total number of directors. The division of our Board into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control of the Company.

DIRECTOR INDEPENDENCE

Our Board has undertaken a review of the independence of our directors and considered whether any director has a relationship which, in the opinion of the Board, could interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director. Our Board has affirmatively determined that Virginia Boulet, Christina C. Correia, Susan Heystee, Ernest Maddock, Stephen A. Skaggs, Phillip M. Eyler and Theodore L. Tewksbury, Ph.D. are each an “independent director,” as defined under the rules of the Nasdaq Stock Market LLC (the “Nasdaq Rules”). In making these determinations, our Board considered the current and prior relationships that each director has with our Company and all other facts and circumstances our Board deemed relevant in determining their independence.

The Nominating and Corporate Governance Committee is responsible for identifying and reviewing the qualifications of potential director candidates and recommending to the Board those candidates to be nominated for election to the Board.

To facilitate the search process for director candidates, the Nominating and Corporate Governance Committee may solicit our current directors and executives for the names of potentially qualified candidates or may ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates or consider director candidates recommended by our stockholders. In connection with his initial election to our Board, Phillip M. Eyler was recommended to serve on our Board by a third party director search firm. Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from us and potential conflicts of interest, and determines if candidates meet the qualifications desired by the Nominating and Corporate Governance Committee of candidates for election as director.

In accordance with our Corporate Governance Guidelines, in evaluating the suitability of individual candidates, the Nominating and Corporate Governance Committee may take into account many factors, including: personal and professional integrity; strong ethics and values; the ability to make mature business judgments; experience in corporate management, such as serving as an officer or former officer of a publicly held company; experience as a board member of another publicly held company; professional and academic experience relevant to the Company’s industry; the strength of the candidate’s leadership skills; experience in finance and accounting and/or executive compensation practices; whether the candidate has the time required for preparation, participation and attendance at Board and

TABLE OF CONTENTS

committee meetings; whether the board has appropriate mix of experience, qualifications and skills to perform its oversight function; and any other relevant qualifications, attributes or skills. In determining whether to recommend a director for re-election, the Nominating and Corporate Governance Committee may also consider the director’s past attendance at meetings and participation in and contributions to the activities of the Board.

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, Ouster, Inc., 350 Treat Avenue, San Francisco, California 94110. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

COMMUNICATIONS BY INTERESTED PARTIES

Any Company stockholder or other interested party who desires to communicate with our Board of Directors, the Chair of our Board, the lead director, if any, any chairperson of a Board committee, or our non-management or independent members of the Board, may do so by addressing such communications to the intended recipient by name or position in care of: Ouster, Inc. to the attention of the General Counsel, 350 Treat Avenue, San Francisco, California 94110.

BOARD LEADERSHIP STRUCTURE AND ROLE IN RISK OVERSIGHT

Our Corporate Governance Guidelines provide the Board with flexibility to select our Chair of the Board, any Vice Chair of the Board and our Chief Executive Officer in the way the Board considers in the best interests of the Company. Therefore, the Board does not have a policy on whether the role of Chair and Chief Executive Officer should be separate or combined and, if it is to be separate, whether the Chair should be selected from the independent directors.

Currently, the roles of Chair of the Board and Chief Executive Officer are separated. In addition, we currently have a Vice Chair of the Board. Our Board continues to believe that the separation of the positions of Chair of the Board and Chief Executive Officer, together with the role of Vice Chair, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of the Board as a whole. For these reasons, our Board has concluded that our current leadership structure is appropriate at this time. Our Board exercises its judgment in establishing, combining or separating the roles of Chair of the Board and Chief Executive Officer as it deems appropriate in light of prevailing circumstances. The Board will continue to exercise its judgment on an ongoing basis to determine the optimal Board leadership structure that the Board believes will provide effective leadership, oversight and direction, while optimizing the functioning of both the Board and management and facilitating effective communication between the two.

If the Chair is a member of management or does not otherwise qualify as independent, the Independent Directors may elect a lead independent director. Presently, the Board has not appointed a lead independent director because the Chair is independent. If applicable, the lead independent director’s responsibilities include, but are not limited to: presiding over all meetings of the Board at which the Chair and any Vice Chair of the Board is not present, including any executive sessions of the independent directors; approving Board meeting schedules and agendas; and acting as the liaison between the independent directors and the Chief Executive Officer and Chair of the Board. When the Chair of the Board is an independent director, the Chair of the Board serves as lead independent director. The Board may modify its leadership structure in the future as it deems appropriate.

Our Board has an active role, as a whole and also at the committee level, in overseeing the management of our risks. Our Board is responsible for general oversight of risks and regular review of information regarding our risks. The Audit Committee is responsible for discussing the Company’s policies with respect to risk assessment and risk management, including guidelines and policies to govern the process by which the Company’s exposure to risk is handled. The Audit Committee is also specifically responsible for overseeing the management of financial, cybersecurity and data privacy risks, including oversight of the measures taken by management to remediate our material weaknesses. The Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation plans and arrangements. The Nominating and Corporate Governance Committee is responsible for overseeing the management of risks associated with the independence of our Board and other corporate governance matters. The Board does not believe that its role in the oversight of our risks affects the Board’s leadership structure.

TABLE OF CONTENTS

EXECUTIVE SESSIONS

The non-management, independent members of the Board meet in regularly scheduled executive sessions, at least twice a year. Theodore L. Tewksbury, as independent Chair of the Board, presides over such executive sessions.

INSIDER TRADING COMPLIANCE POLICY

Our Board has adopted an Insider Trading Compliance Policy that governs the purchase, sale and/or other disposition of the Company’s securities by directors, officers and other employees of the Company. We believe our Insider Trading Compliance Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, as well as listing standards applicable to the Company. It is also our policy to comply with applicable insider trading laws and regulations with respect to transactions in our own securities. A copy of our Insider Trading Compliance Policy is attached as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC on March 2, 2026.

The Insider Trading Compliance Policy prohibits our directors, officers and employees and any entities they control from purchasing financial instruments such as prepaid variable forward contracts, equity swaps, collars, and exchange funds, or otherwise engaging in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s equity securities, or that may cause an officer, director or employee to no longer have the same objectives as the Company’s other stockholders.

RECOVERY OF ERRONEOUSLY AWARDED COMPENSATION POLICY

Ouster has adopted a Recovery of Erroneously Awarded Compensation Policy that, consistent with SEC and Nasdaq rules, requires the clawback of certain erroneously awarded compensation. In conformance with these rules, our policy requires the clawback by the Company of certain incentive-based compensation paid to current and former executive officers in the event that the Company is required to prepare an accounting restatement pursuant to which such compensation would not properly have been paid.

EQUITY AWARD TIMING POLICIES AND PRACTICE

We generally grant equity awards at regularly scheduled Compensation Committee meetings. We do not grant equity awards in anticipation of the release of material nonpublic information and we do not time the release of material nonpublic information for the purpose of affecting the value of executive compensation. In the event material nonpublic information becomes known to the Compensation Committee before granting an equity award, the Compensation Committee will consider such information and use its business judgment to determine whether to delay the grant of equity to avoid any appearance of impropriety.

We have not granted stock options or similar option-like instruments to our service providers since 2021. Accordingly, during fiscal year 2025, we did not grant stock options or similar option like instruments to our NEOs during the four business days prior to or the one business day following the filing of our periodic reports or the filing or furnishing of a Form 8-K that discloses material nonpublic information.

CODE OF BUSINESS CONDUCT AND ETHICS

We have adopted a Code of Business Conduct and Ethics (the “Code of Conduct”) that applies to all of our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A copy of our Code of Conduct is available on our Investors website at investors.ouster.com in the “Corporate Governance” section. We expect that any amendments to the Code of Conduct, or any waivers of its requirements, that are required to be disclosed by SEC or Nasdaq Rules will be disclosed on our website. We granted no waivers under our Code of Conduct with respect to our executive officers or directors in fiscal year 2025.

ATTENDANCE BY MEMBERS OF THE BOARD OF DIRECTORS AT MEETINGS

There were 9 meetings of the Board during the fiscal year ended December 31, 2025. During the fiscal year ended December 31, 2025, each incumbent director attended at least 75% of the aggregate of (i) all meetings of the Board during the period in which he or she served as a director and (ii) all meetings of the committees on which he or she served during the period in which he or she served as a director. Last year, all of our then-current directors attended the 2025 annual meeting of stockholders.

TABLE OF CONTENTS

Under our Corporate Governance Guidelines, which are available on our website at www.ouster.com, a director is expected to spend the time and effort necessary to properly discharge his or her responsibilities. Accordingly, a director is expected to regularly prepare for and attend meetings of the Board and all committees on which the director sits (including separate meetings of the independent directors), and the annual meeting of stockholders, with the understanding that, on occasion, a director may be unable to attend a meeting. All directors are expected to attend all Board and applicable committee meetings. A director who is unable to attend a meeting of the Board or a committee of the Board is expected to notify the Chair of the Board or the Chair of the appropriate committee in advance of such meeting, and, whenever possible, participate in such meeting via teleconference in the case of an in-person meeting.

Narrative to the Summary Compensation Table

2025 Annual Base Salaries

Our named executive officers each receive a base salary to compensate them for services rendered to our company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. For 2025, the annual base salaries of Mr. Pacala, Mr. Frichtl and Mr. Gianella were $400,000, $400,000 and $375,000, respectively.

Our Compensation Committee retains the discretion to increase the annual base salaries of our named executive officers from time to time.

Short-Term Incentive Compensation

For 2025, each of our executive officers was eligible to earn performance-based, short-term incentive compensation based on pre-set financial metrics. During 2025, our Compensation Committee set Mr. Pacala’s and Mr. Frichtl’s target bonus opportunity for 2025 at 100% and 50% of his annual base salary, respectively, and established Mr. Gianella’s

TABLE OF CONTENTS

target bonus opportunity for 2025 at 65% of his annual base salary, pro-rated for his partial year of service. In early 2026, our Compensation Committee determined that the financial metrics for 2025 were achieved at 119.9%. The bonuses set forth in the 2025 Summary Compensation Table were paid in cash in March 2026.

In connection with Mr. Gianella’s commencement of employment in May 2025, our Compensation Committee approved a one-time sign-on bonus of $100,000, paid in two equal installments in May and November 2025. Mr. Gianella is required to repay the sign-on bonus in the event he resigns his employment with us for any reason or his employment is terminated by us for cause, in each case, prior to May 19, 2026.

Our Compensation Committee approved a similar performance-based program for 2026 and retains the discretion to award discretionary bonuses and to make discretionary adjustments to bonus targets and amounts from time to time.

Equity Compensation

We grant equity awards, typically comprised of restricted stock or restricted stock units, to our employees, including our named executive officers, in order to attract and retain them, as well as to align their interests with the interests of our stockholders.

Our Compensation Committee granted Mr. Pacala 275,000 restricted stock units in March 2025, Mr. Frichtl 175,000 restricted stock units in April 2025 and Mr. Gianella 300,000 restricted stock units in May 2025. The awards of restricted stock units for Mr. Pacala and Mr. Frichtl vest in six substantially equal installments on each quarterly anniversary of September 11, 2025, in each case, subject to continued service to us through the applicable vesting dates. Mr. Gianella’s award of restricted stock units vests 1/3^rd on June 11, 2026 and then in eight quarterly installments thereafter, subject to continued service to us through the applicable vesting dates.

Other Elements of Compensation

Retirement Savings and Health and Welfare Benefits

We maintain a 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. Our named executive officers are eligible to participate in the 401(k) plan on the same terms as other full-time employees. We match 4% of a participant’s annual eligible contribution to the 401(k) plan, up to the IRS limit. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans. These health and welfare plans include medical, dental and vision benefits; short-term and long-term disability insurance; and supplemental life and AD&D insurance.

Perquisites and Other Personal Benefits

We determine perquisites on a case-by-case basis and will provide a perquisite to a named executive officer when we believe it is necessary to attract or retain the named executive officer. We did not provide any perquisites or personal benefits to our named executive officers not otherwise made available to other employees in 2025.

DIRECTOR COMPENSATION

For fiscal year 2025, directors who were executives of the Company were not eligible to receive additional compensation for their services as directors.

We maintain our Third Amended and Restated Non-Employee Director Compensation Program (the “Non-employee Director Compensation Program”) for our non-employee directors, which was most recently amended in April 2024. Pursuant to the Non-Employee Director Compensation Program, our non-employee directors receive cash compensation as follows:

•	Each non-employee director receives an annual cash retainer in the amount of $40,000 per year.

•	Any chair of our Board receives an additional annual cash retainer in the amount of $60,000 per year.

•	Any Lead Director and, effective in 2024, any Vice Chair receives an additional annual cash retainer in the amount of $60,000 per year.

•

The chair of the audit committee receives additional annual cash compensation in the amount of $20,000 per year for such chair’s service on the audit committee. Each non-chair member of the audit committee receives additional annual cash compensation in the amount of $10,000 per year for such member’s service on the audit committee.

•

The chair of the compensation committee receives additional annual cash compensation in the amount of $15,000 per year for such chair’s service on the compensation committee. Each non-chair member of the compensation committee receives additional annual cash compensation in the amount of $6,000 per year for such member’s service on the compensation committee.

•

The chair of the nominating and corporate governance committee receives additional annual cash compensation in the amount of $10,000 per year for such chair’s service on the nominating and corporate governance committee. Each non-chair member of the nominating and corporate governance committee receives additional annual cash compensation in the amount of $5,000 per year for such member’s service on the nominating and corporate governance committee.

•

Each non-employee director may also elect to receive all or part of his or her annual cash retainer in the form of restricted stock units under our 2021 Incentive Award Plan or, effective in 2024 and to the extent permitted, the Velodyne Plan. Elections to convert all or a portion of the annual cash retainer into restricted stock units must generally be made on or prior to December 31 of the year prior to the year in which the annual cash retainer is scheduled to be paid, or such earlier deadline as established by our Board of Directors or compensation committee. Each individual who first becomes a non-employee director is permitted to elect to convert the annual cash retainer payments scheduled to be paid in the same calendar year into restricted stock units, provided that the election is made prior to the date the individual becomes a non-employee director. Restricted stock units granted in lieu of all or a portion of the annual cash retainer are fully vested on the date of grant, with the number of restricted stock units determined by dividing the amount of the applicable portion of the annual cash retainer by the average closing trading price of our common stock over the 30 days immediately preceding the date of grant.

Under the Non-Employee Director Compensation Program, upon the initial appointment or election of a non-employee director, the director will automatically be granted under our 2021 Incentive Award Plan or, effective in 2024 and to the extent permitted, the Velodyne Plan (a) an award of restricted stock units with respect to a number of shares of our common stock calculated by dividing (i) $300,000 by (ii) the fair market value of a share of our common stock as of the date of grant that vests in equal quarterly installments over three years and (b) an award of restricted stock units with respect to a number of shares of our common stock calculated by dividing (i) the product of $175,000 multiplied times a fraction, the numerator of which is the number of full months between the date of appointment or election and the scheduled date of our next annual stockholder meeting, and the denominator of which is 12, by (ii) the fair market value of a share of our common stock as of the date of grant that vests in equal quarterly installments through the date of the next annual stockholders meeting. Additionally, on the date of each annual stockholders meeting, each non-employee

TABLE OF CONTENTS

director automatically will be granted an award of restricted stock units with respect to a number of shares of our common stock calculated by dividing (a) $175,000 by (b) the fair market value of our common stock as of the date of grant that vests in equal quarterly installments through the earlier of the first anniversary of the date of grant or the next annual stockholders meeting.

Additionally, the Non-Employee Director Compensation Program provides that non-employee directors may elect to defer all or part of the settlement of restricted stock units granted to them.

In the event of a change in control, all restricted stock units and other equity-based awards held by any non-employee director, will vest immediately prior to such change in control.

Director Compensation Table for Fiscal 2025

The following table contains information concerning the compensation of our non-employee directors in fiscal 2025:


Name	Fees Earned or Paid in Cash ($)⁽¹⁾	Stock Awards ($)⁽²⁾	Total ($)
Virginia Boulet	47,663	275,770	323,433

For 2025, Ms. Heystee elected to receive her annual retainer in fully-vested restricted stock units in lieu of cash. The amount reported reflects the cash fees that would have been paid had the director not been granted restricted stock units in lieu of an annual cash retainer. The grant date fair value of the restricted stock units that is in excess of the amount of cash fees foregone is reported in the Stock Awards column. Our non-employee directors were also able to defer delivery of the shares underlying vested restricted stock units. As of December 31, 2025, Dr. Tewksbury held 33,820 vested restricted stock units for which delivery of the underlying shares has been deferred.

(2)

Amounts reflect the full grant-date fair value of stock awards granted during fiscal 2025 computed in accordance with ASC Topic 718, rather than the amounts paid to or realized by the named individual. We provide information regarding the assumptions used to calculate the grant date fair value of the restricted stock units granted to our non-employee directors in Note 11 of our financial statements included in our Form 10-K.

The table below shows the aggregate numbers of shares underlying unvested restricted stock units held as of December 31, 2025 by each non-employee director who was serving as of December 31, 2025. Our non-employee directors did not hold any options or other equity awards that were subject to vesting as of December 31, 2025.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

Our Board has adopted a written Related Person Transaction Policy and Procedures, setting forth the policies and procedures for the review and approval or ratification of related person transactions. A “related person transaction” is a transaction, arrangement or relationship in which the Company or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest. A “related person” means:

•	any person who is, or at any time during the applicable period was, one of our executive officers, directors or nominees to become a director;

•	any person who is known to be the beneficial owner of more than 5% of any class our voting stock;

•

any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, son-in-law, daughter-in-law, brother-in-law or sister-in-law of a director, executive officer, nominee or beneficial owner of more than 5% of our voting stock, and any person (other than a tenant or employee) sharing the household of such director, executive officer, nominee or beneficial owner of more than 5% of our voting stock; or

•	any firm, corporation or other entity in which any of the foregoing persons is employed or is a general partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest in any class of our voting stock.

We have policies and procedures designed to minimize potential conflicts of interest arising from any dealings the Company may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to our Audit Committee charter, the Audit Committee has the responsibility to review related person transactions.

TRANSACTIONS RELATED TO DIRECTORS, EQUITY HOLDERS AND EXECUTIVE OFFICERS

Other than our compensation arrangements with directors and executive officers described elsewhere in this proxy statement and indemnification agreements with each of our directors and executive officers, the following are certain transactions since January 1, 2024 and currently proposed transactions, to which we were a participant or will be a participant, in which: (1) the amount involved exceeded or will exceed $120,000, and (2) any of our directors, executive officers or holders of more than 5% of our common stock, or any member of the immediate family of the foregoing persons or entities, had or will have a direct or indirect material interest.

Registration Rights

On March 11, 2021, Ouster, Colonnade Sponsor LLC (the “Sponsor”), Colonnade WPB LLC (the “Sponsor PIPE Purchaser”), certain members of the Sponsor and the Sponsor PIPE Purchaser and certain former stockholders of our subsidiary, Ouster Technologies, Inc. entered into the Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”). Such parties had registration rights to require the Company to register a sale of any of our securities held by them pursuant to a registration rights agreement. The holders of these securities were entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders had certain “piggy-back” registration rights with respect to future registration statements. The Company bore the expenses incurred in connection with the filing of any such registration statements. The Registration Rights Agreement expired in March 2026.

Section 16(a) of the Exchange Act requires our executive officers and directors, our principal accounting officer and persons who beneficially own more than 10% of our common stock to file with the SEC reports of their ownership and changes in their ownership of our common stock. To our knowledge, based solely on review of the copies of such reports and amendments to such reports with respect to the year ended December 31, 2025 filed with the SEC and on written representations by our directors and executive officers, all required Section 16 reports under the Exchange Act for our directors, executive officers, principal accounting officer and beneficial owners of greater than 10% of our common stock were filed on a timely basis during the year ended December 31, 2025.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

During the year ended December 31, 2025, Susan Heystee, Ernest Maddock, Phillip M. Eyler and Stephen A. Skaggs served on the Compensation Committee of the Board. No member of our Compensation Committee is an officer or employee of the Company. During the year ended December 31, 2021, Susan Heystee served as Interim Chief Revenue Officer of the Company. Ms. Heystee did not serve on the Compensation Committee during the period that she served as Interim Chief Revenue Officer.

During the year ended December 31, 2025, none of our executive officers served as a member of the board of directors or compensation committee, or other committee serving an equivalent function, of any other entity that has one or more of its executive officers serving as a member of our Board or Compensation Committee.

STOCKHOLDERS’ PROPOSALS

Stockholders who intend to have a proposal considered for inclusion in our proxy materials for presentation at our 2027 annual meeting of stockholders pursuant to Rule 14a-8 under the Exchange Act must submit the proposal to our offices at 350 Treat Avenue, San Francisco, California 94110 in writing not later than [ ], 2026 (which is 120 days prior to [ ], 2027, the one-year anniversary of the mailing of the Company’s 2026 definitive proxy statement).

Stockholders intending to present a proposal at the 2027 annual meeting of stockholders, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Bylaws. Our Bylaws require, among other things, that our Secretary receive written notice from the stockholder of record of the stockholder’s intent to present such proposal or nomination not earlier than the 120^th day and not later than the 90^th day prior to the first anniversary of the preceding year’s annual meeting. Therefore, we must receive notice of such a proposal or nomination for the 2027 annual meeting of stockholders no earlier than February 17, 2027 and no later than March 19, 2027. The notice must contain the information required by the Bylaws, a copy of which is available upon request to our Secretary.
