#### PROXY STATEMENT

#### FOR THE 2026 ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON JUNE 9, 2026 AT 9:00 A.M., PACIFIC TIME

#### QUESTIONS AND ANSWERS
The information provided in the "question and answer" format below is for your convenience only and is merely a summary of information contained in this proxy statement. You should read this entire proxy statement carefully.

Unless the context indicates otherwise, references in this proxy statement to the "***Company***," "***Rigetti***," "***Rigetti Computing***," "***we***," "***us***," "***our***" and similar terms refer to Rigetti Computing, Inc.

#### Why did I receive a notice regarding the availability of proxy materials on the internet?
Pursuant to rules adopted by the Securities and Exchange Commission (the "***SEC***"), we have elected to provide access to our proxy materials over the internet. Accordingly, we have sent you a Notice of Internet Availability of Proxy Materials (the "***Notice***") because our Board of Directors is soliciting your proxy to vote at the 2026 Annual Meeting of Stockholders (the "***Annual Meeting***"), including at any adjournments or postponements thereof. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or to request a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice.

The proxy materials, consisting of the Notice, this Proxy Statement, the proxy card, and our 2025 Annual Report on Form 10-K (the "***Annual Report***"), will be mailed to our stockholders of record entitled to vote at the Annual Meeting on or about April 24, 2026.

#### Will I receive any other proxy materials by mail?
You will not receive any additional proxy materials via mail unless you request a printed copy in accordance with the instructions set forth in the Notice. We may elect, in our discretion, to send you a proxy card, along with a second Notice, on or after 10 calendar days have passed since our first mailing of the Notice.

#### How do I attend, participate in, and ask questions during the Annual Meeting?
We will be hosting the Annual Meeting via live webcast only. You are entitled to attend the Annual Meeting live online at www.virtualshareholdermeeting.com/RGTI2026 if you were a stockholder as of the close of business on April 15, 2026, referred to as the "Record Date." The Annual Meeting will start at 9:00 a.m., Pacific Time, on Tuesday, June 9, 2026. Stockholders attending the Annual Meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting.

In order to enter the Annual Meeting, you will need the 16-digit control number, which is included in the Notice or on your proxy card if you are a stockholder of record or included with your voting instruction card and voting instructions received from your broker, bank or other agent if you hold your shares in "street name." Instructions on how to attend and participate are available at www.proxyvote.com. We recommend that you log in a few minutes before 9:00 a.m., Pacific Time, to ensure you are logged in when the Annual Meeting starts. The virtual meeting room will open 15 minutes before the start of the Annual Meeting. If you are a beneficial owner, you should contact the bank, broker or other institution where you hold your account well in advance of the Annual Meeting if you have questions about obtaining your proxy Notice control number.

[**TABLE OF CONTENTS**](#TOC)

If you would like to submit a question during the Annual Meeting, you may log in at www.virtualshareholdermeeting.com/RGTI2026 using your control number, type your question into the appropriate box, and click "Submit."

To ensure that we have a productive and efficient meeting, and in fairness to all stockholders in attendance, you will also find posted our rules of conduct for the Annual Meeting when you log in prior to its start. These rules of conduct will include the following guidelines:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • You may submit questions electronically through the meeting portal during the Annual Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Only stockholders of record as of the Record Date for the Annual Meeting and their proxy holders may submit questions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Please direct all questions to Dr. Subodh Kulkarni, our Chief Executive Officer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Please include your name and affiliation, if any, when submitting a question.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Limit your remarks to one brief question that is relevant to the Annual Meeting and/or our business and ask only questions that are respectful of your fellow stockholders and meeting participants. Questions and answers may be grouped by topic, and substantially similar questions may be grouped and answered once.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Questions may also be ruled as out of order if they are, among other things, irrelevant to our business, related to pending or threatened litigation, disorderly, repetitious statements already made, or in furtherance of the speaker's own personal, political or business interests.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Be respectful of your fellow stockholders and Annual Meeting participants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • No recordings of the Annual Meeting are permitted.

#### What if I have technical difficulties or trouble accessing the Annual Meeting?
We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual Annual Meeting. If you encounter any difficulties accessing the virtual Annual Meeting during the check-in or meeting time, please call the technical support number that will be posted at www.virtualshareholdermeeting.com/RGTI2026. Technical support will be available starting 15 minutes prior to the start of the Annual Meeting.

#### Will a list of record stockholders as of the Record Date be available?
For a period of ten days ending the day prior to the Annual Meeting, a list of stockholders entitled to vote at the Annual Meeting as of the close of business on the Record Date will be available at our corporate headquarters, located at 775 Heinz Avenue, Berkeley, CA 94710, for examination by any stockholder of record for a legally valid purpose upon written request. Please direct your written request to us via email at IR@rigetti.com.

#### Who can vote at the Annual Meeting?
Only stockholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. On the Record Date, there were 332,345,548 shares of common stock, par value $0.0001 per share, of the Company (the "Common Stock" or our "Common Stock"), outstanding and entitled to vote.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***Stockholder of Record: Shares Registered in Your Name***. If, on the Record Date, your shares were registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, then you are a stockholder of record.

As a stockholder of record, you may vote online during the Annual Meeting or by proxy in advance. Whether or not you plan to attend the Annual Meeting, we urge you to vote your shares by proxy in advance of the Annual Meeting through the internet, by telephone or by completing and returning a printed proxy card that you may request or that we may elect to deliver at a later time to ensure your vote is counted.

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***Beneficial Owner: Shares Held through a Broker or Bank***. If, on the Record Date, your shares were held not in your name, but rather in an account at a brokerage firm, bank or other similar organization, then you are the beneficial owner of shares held in "street name" and the Notice is being forwarded to you by that organization. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, check with your brokerage firm, bank, dealer or other similar organization, and follow the instructions you receive from your brokerage firm, bank, dealer or other similar organization prior to the Annual Meeting.

#### How many votes do I have?
Each holder of shares of our Common Stock will have one vote per share of Common Stock held as of the Record Date.

#### What am I voting on?
There are two matters scheduled for a vote:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***Proposal 1***: Election of one Class I director, Dr. Subodh Kulkarni, to hold office until the 2029 Annual Meeting of Stockholders; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***Proposal 2***: Ratification of the selection of BDO USA, P.C. as the independent registered public accounting firm for the Company for the fiscal year ending December 31, 2026.

#### What if another matter is properly brought before the Annual Meeting?
Our Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, the accompanying proxy gives the persons named as proxy the authority to vote on those matters in accordance with their best judgment.

#### How do I vote?
If you are a stockholder of record and your shares are registered directly in your name, you may do the following to either vote your shares or submit a proxy to have your shares voted:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***By Internet***. To vote by submitting a proxy through the internet, go to www.proxyvote.com to complete an electronic proxy card. You will be asked to provide your control number from the Notice. Your Internet proxy must be received by 8:59 p.m., Pacific Time, on June 8, 2026 to be counted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***By Telephone***. Call 1-800-690-6903 toll-free from the United States, U.S. territories and Canada, and follow the instructions on the Notice. You will be asked to provide your control number from the Notice. Your telephone proxy must be received by 8:59 p.m., Pacific Time, on June 8, 2026 to be counted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***By Proxy Card***. Complete, sign and date the proxy card that may be requested and return it promptly in the envelope provided. If we receive your signed proxy card to us before the Annual Meeting, we will vote your shares as you direct. Your proxy card must be received by 8:59 p.m., Pacific Time, on June 8, 2026 to be counted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ***Online During the Annual Meeting***. Access the Annual Meeting by visiting www.virtualshareholdermeeting.com/RGTI2026 and providing your control number from the Notice.

If your shares of Common Stock are held in street name (i.e., held for your account by a broker, bank or other nominee), you should have received a notice containing voting instructions from that organization rather than from us. You should follow the instructions in the notice to ensure your vote is counted. Access the Annual Meeting by following the instructions you receive and using the control number provided by your bank, broker or other nominee.

 **Internet voting during the Annual Meeting and/or internet proxy voting in advance of the Annual Meeting allows you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your vote instructions. Please be aware that you must bear any costs associated with your internet access.** 

------

[**TABLE OF CONTENTS**](#TOC)

#### Can I vote my shares by filling out and returning the Notice?
No. The Notice identifies the items to be voted on at the Annual Meeting, but you cannot vote by marking the Notice and returning it. The Notice provides instructions on how to vote by proxy in advance of the Annual Meeting through the internet, by telephone, using a printed proxy card or online during the Annual Meeting.

#### What does it mean if I receive more than one Notice?
If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each Notice you receive to ensure that all of your shares are voted.

 **If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without marking specific voting selections, what happens?** 

If you are a stockholder of record and do not have your shares voted by submitting a proxy through the internet, by telephone, by completing the proxy card that may be delivered to you or online during the Annual Meeting, your shares will not be voted.

If you return a signed and dated proxy card without indicating how you want your shares voted on each proposal or otherwise submit a proxy without making voting selections for each proposal, your shares will be voted in accordance with the recommendations of our Board of Directors: "**FOR**" the election of the nominee named in this Proxy Statement for director; and "**FOR**" the ratification of the selection of BDO USA, P.C. as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026. If any other matter is properly presented at the Annual Meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

 **If I am a beneficial owner of shares held in "street name" and I do not provide my broker or bank with voting instructions, what happens?** 

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other agent how to vote your shares, your broker, bank or other agent may still be able to vote your shares in its discretion. Under the rules of the New York Stock Exchange ("***NYSE***"), brokers, banks and other securities intermediaries that are subject to NYSE rules may use their discretion to vote your "uninstructed" shares with respect to matters considered to be "routine" under NYSE rules, but not with respect to "non-routine" matters under NYSE rules. All brokers registered as members with NYSE are subject to NYSE rules and, accordingly, NYSE rules apply to the voting of all shares held in a brokerage account, including shares of a company like ours listed on the Nasdaq Stock Market ("***Nasdaq***"). In this regard, Proposal 1 is considered to be "non-routine" under NYSE rules meaning that your broker may not vote your shares on Proposal 1 in the absence of your voting instructions. However, Proposal 2 is considered to be a "routine" matter under NYSE rules, meaning that if you do not return voting instructions to your broker by its deadline, your shares may be voted by your broker in its discretion on Proposal 2.

 ***If you are a beneficial owner of shares held in street name, and you do not plan to attend the Annual Meeting, in order to ensure your shares are voted in the way you would prefer, you <u>must</u> provide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.***

#### What are "broker non-votes"?
As discussed above, when a beneficial owner of shares held in "street name" does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed to be "non-routine," the broker or nominee cannot vote the shares. When there is at least one "routine" matter that the broker, bank or other securities intermediary votes on, the shares that are unvoted on "non-routine" matters are counted as "broker non-votes." Proposal 2 is considered to be a "routine" matter and therefore brokers, banks or other securities intermediaries will have discretion to vote your shares on this proposal without instructions from you. Proposal 1 is considered to be "non-routine" and unvoted shares will be counted as "broker non-votes" with respect to Proposal 1.

------

[**TABLE OF CONTENTS**](#TOC)

#### Can I change my vote after submitting my proxy?
***Stockholder of Record: Shares Registered in Your Name***. If you are a stockholder of record, then yes, you can revoke your proxy at any time before the final vote at the Annual Meeting. You may revoke your proxy in any one of the following ways:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Submit another properly completed proxy card with a later date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Grant a subsequent proxy by telephone or through the internet.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Attend the Annual Meeting and vote online during the meeting. Simply attending the Annual Meeting will not, by itself, revoke your proxy. Even if you plan to attend the Annual Meeting, we recommend that you also submit your proxy in advance of the Annual Meeting by signing and returning a proxy card, by telephone or through the internet so that your vote will be counted if you later decide not to attend the Annual Meeting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Send written notice of revocation to our Corporate Secretary, which must be received by the Company at IR@rigetti.com before the time the Annual Meeting begins.

Your most current proxy card or telephone or internet proxy is the one that is counted.

***Beneficial Owner: Shares Registered in the Name of Broker or Bank***. If you are a beneficial owner and your shares are held in "street name" by your broker, bank or other agent, you should follow the instructions provided by your broker, bank or other agent.

#### How are votes counted?
Votes will be counted by the inspector of election appointed for the Annual Meeting, who will separately count, for the proposal to elect one director, votes "**FOR**," "**WITHHOLD**" and broker non-votes; and, with respect to the other proposal, votes "**FOR**," "**AGAINST**" and abstentions. Broker non-votes on Proposal 1 will have no effect and will not be counted towards the vote total for this proposal. "Withhold" votes will have no effect on the outcome of the vote with respect to Proposal 1. Abstentions on Proposal 2 will have the same effect as an "Against" vote. We do not anticipate broker non-votes for Proposal 2 because such proposal is considered to be a "routine" matter under NYSE rules, and accordingly, your broker, bank, dealer or other agent will have discretion to vote your shares on this proposal without instructions from you.

#### How many votes are needed to approve each proposal?
The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Proposal <br> Number** | **Proposal Description**  | **Vote Required for Approval**  | **Effect of <br> Abstentions or <br> Withhold Votes, <br> as applicable**  | **Effect of <br> Broker Non- <br> Votes**  |
| 1  | Election of Directors | The nominee receiving the most "**FOR**" votes from the holders of shares, either present in person or represented by proxy at the meeting and entitled to vote on the election of directors will be elected. | No effect  | No effect  |
| 2  | Ratification of the selection of BDO USA, P.C. as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026 | "**FOR**" votes from a majority of the voting power of the shares of Common Stock present in person or represented by proxy at the meeting and entitled to vote on the matter. | Against  | Not applicable; <br> brokers will have discretion to vote  |

[**TABLE OF CONTENTS**](#TOC)

#### What is the quorum requirement?
A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding one-third (33-1/3%) of the voting power of the outstanding shares of Common Stock entitled to vote at the meeting are present at the Annual Meeting in person, by remote communication or by proxy duly authorized.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you attend the Annual Meeting using your 16-digit control number. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairperson of the Annual Meeting or the holders of a majority of the voting power of shares present at the Annual Meeting or represented by proxy and entitled to vote thereon may adjourn the Annual Meeting to another date.

#### How can I find out the results of the voting at the Annual Meeting?
Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within 4 business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within 4 business days after the Annual Meeting, we intend to file a Form 8-K to publish preliminary results and, within 4 business days after the final results are known to us, file an additional Form 8-K to publish the final results.

#### Who is paying for this proxy solicitation?
We will pay for the entire cost of soliciting proxies. We have engaged Alliance Advisors, LLC, a proxy solicitation organization, to assist in this solicitation process for a fee of $20,000, plus reasonable out-of-pocket expenses. In addition to these proxy materials, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

#### When are stockholder proposals and director nominations due for next year's annual meeting?
 *Requirements for stockholder proposals to be brought before an annual meeting.* 

Our bylaws (as amended and restated from time to time, our "***Bylaws***") provide that, for stockholder director nominations or other proposals to be considered at an annual meeting, the stockholder must give timely notice thereof in writing to our Corporate Secretary at Rigetti Computing, Inc., 775 Heinz Avenue Berkeley, CA 94710. To be timely for the 2027 annual meeting of stockholders, a stockholder's notice must be delivered to or mailed and received by our Corporate Secretary at our principal executive offices between February 9, 2027 and March 11, 2027; provided that, in the event that the date of the 2027 annual meeting of stockholders is advanced more than 30 days prior to or delayed by more than 30 days after the anniversary of this year's Annual Meeting, you must give the required notice not earlier than the 120th day prior to the 2027 annual meeting of stockholders and not later than the close of business on the later of the 90th day prior to such annual meeting or, if later than the 90th day prior to such annual meeting, the 10th day following the day on which public announcement of the date of such meeting is first made by the Company. A stockholder's notice to the Corporate Secretary must also set forth the information required by our Bylaws.

#### PROPOSAL 1 ELECTION OF DIRECTORS

#### General

Our Board of Directors currently consists of six directors. There are two Class I directors whose term of office expires in 2026, Dr. Subodh Kulkarni and Ms. H. Gail Sandford. On March 19, 2026, Ms. Sandford notified the Company that she would not stand for re-election to the Board of Directors upon the completion of her current term as a director, which expires at the Annual Meeting. Effective immediately before the opening of the polls for the election of directors at the Annual Meeting, the size of the Board of Directors will be reduced and will consist of five directors. The Company thanks Ms. Sandford for her commitment and service to the Company.

Upon the recommendation of the Nominating and Corporate Governance Committee, our Board of Directors has nominated Dr. Subodh Kulkarni for election as a Class I director at the Annual Meeting to serve until the 2029 Annual Meeting of Stockholders, or until his successor is duly elected and qualified, or, if sooner, until the director's death, resignation or removal.

If Dr. Kulkarni ceases to be a candidate for election by the time of the Annual Meeting (a contingency which the Board of Directors does not expect to occur), such proxies may be voted by the proxyholders in accordance with the recommendation of the Board of Directors.

Each member of our Board of Directors, except Dr. Subodh Kulkarni and Thomas J.

#### INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

#### Independence of the Board of Directors
Under the Nasdaq listing standards, a majority of the members of our Board of Directors must qualify as "independent," as affirmatively determined by our Board of Directors.

Based on information provided by each director concerning his or her background, employment and affiliations, the Board of Directors has determined that none of our directors, other than Dr. Kulkarni, has any relationships that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director, and affirmatively determined that each of Thomas J. Iannotti, Michael Clifton, Alissa M. Fitzgerald, Ray O. Johnson and H. Gail Sandford is "independent" as that term is defined under the Nasdaq listing standards. The Board of Directors also determined that each member of our Audit, Compensation and Nominating and Corporate Governance Committees satisfies the independence standards for such committees established by the SEC and the Nasdaq listing standards, as applicable.

#### No Family Relationships
There are no family relationships between any of our executive officers, directors or director nominees.

#### Board of Directors Leadership Structure
Our Board of Directors has an independent chairman, Mr. Thomas J. Iannotti, who has authority, among other things, to call and preside over board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board of Directors. Accordingly, the Chairman of the Board of Directors has substantial ability to shape the work of the Board of Directors. We believe that separation of the positions of Chairman and Chief Executive Officer reinforces the independence of the Board of Directors in its oversight of the business and affairs of the Company. In addition, we believe that having an independent Chairman creates an environment that is more conducive to objective evaluation and oversight of management's performance, increasing management accountability and improving the ability of the Board of Directors to monitor whether management's actions are in the best interests of the Company and its shareholders. As a result, we believe that having an independent Chairman can enhance the effectiveness of the Board of Directors as a whole.

#### Role of the Board of Directors in Risk Oversight
One of the key functions of the Board of Directors is informed oversight of our risk management process. In particular, our Board of Directors is responsible for monitoring and assessing strategic risk exposure, including a determination of the nature and level of risk appropriate for our company. The Board of Directors administers this oversight function directly through the Board of Directors as a whole, as well as through various standing committees of the Board of Directors that address risks inherent in their respective areas of oversight. Our Board of Directors and its committees consider specific risk topics, including risks associated with our strategic plan, business operations, capital structure, information technology, data privacy and cybersecurity. It is the responsibility of the committee chairs to report findings regarding material risk exposures to the Board of Directors.

Our audit committee has the responsibility to consider and discuss with management and the auditors, as appropriate, our guidelines and policies with respect to financial risk management and financial risk assessment, including our financial risk exposures and the steps our management takes to monitor and control such exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. Our audit committee also monitors compliance with legal and regulatory requirements. Areas of focus for the audit committee include policies and other matters relating to our investments, cash management, financial risk exposures, the adequacy and effectiveness of our information security policies and practices in addition to oversight of our cybersecurity risk management processes. Our compensation committee assesses and monitors whether our compensation plans, policies and programs comply with applicable legal and regulatory requirements and have the potential to encourage excessive risk-taking, including risks related to executive compensation and overall compensation and benefit strategies, plans, arrangements, practices and policies. Our nominating and corporate governance committee oversees

------

[**TABLE OF CONTENTS**](#TOC)

and reviews with management any major legal compliance risk exposures and the steps management has taken to monitor or mitigate such exposures and monitors the effectiveness of our corporate governance structure, including whether it is successful in preventing illegal or improper liability-creating conduct.

In connection with its reviews of the operations and corporate functions of our company, our Board of Directors addresses the primary risks associated with those operations and corporate functions. In addition, our Board of Directors reviews the risks associated with our company's business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies. While the Board of Directors and its committees oversee risk management strategy, management is responsible for implementing and supervising day-to-day risk management processes and reporting to the Board of Directors and its committees on such matters.

#### Meetings of the Board of Directors and its Committees
The Board of Directors met four times during the fiscal year ended December 31, 2025. Each member of the Board of Directors attended 75% or more of the aggregate number of meetings of the Board of Directors and of the committees on which he or she served, held during the portion of the last fiscal year for which he or she was a director or committee member.

Consistent with applicable Nasdaq listing standards, during the fiscal year ended December 31, 2025, our non-management directors met four times in executive sessions at which only non-management directors were present.

We encourage our directors and director nominees to attend our annual meetings of stockholders. In 2025, all of our directors attended the annual meeting of stockholders.

#### Information Regarding Committees of the Board of Directors
The Board of Directors has three standing committees: an audit committee, a compensation committee and a nominating and corporate governance committee. Each committee met four times during the fiscal year ended December 31, 2025. In November 2025, at the recommendation of the compensation committee, our Board established the Equity Award Committee (defined below) for the purpose of the Board delegating authority to the Equity Award Committee pursuant to the Company's 2022 Equity Incentive Plan (the "***2022 Plan***") to make grants of restricted stock unit ("***RSU***") awards to certain new hire non-executive employees of the Company. See "—Equity Award Committee" below for more information.

The Board of Directors has adopted a written charter for the audit committee, the compensation committee and the nominating and corporate governance committee. Copies of the charters for each of these committees are available on the investor relations portion of our website (https://investors.rigetti.com/).

Below is a description of each committee of the Board of Directors.

#### Audit Committee
The audit committee currently consists of Ray Johnson, H. Gail Sandford, Alissa M. Fitzgerald and Michael Clifton, each of whom the Board of Directors has determined satisfies the independence requirements for audit committee service under Nasdaq listing standards and Rule 10A-3(b)(1) of the Exchange Act. The chair of the audit committee is Mr. Clifton. From March 2022 until the expiration of her term as a director at the 2025 annual meeting of stockholders, Cathy McCarthy served on the audit committee, and the Board of Directors had also determined that Ms. McCarthy satisfied the independence standards and Rule 10A-3(b)(1) of the Exchange Act. The Board of Directors has determined that each of Mr. Clifton and Dr. Johnson is an "audit committee financial expert" within the meaning of SEC regulations. Each member of the audit committee can read and understand fundamental financial statements in accordance with applicable requirements. In arriving at these determinations, the Board of Directors examined each audit committee member's scope of experience and the nature of their employment.

The primary purpose of the audit committee is to discharge the responsibilities of the Board of Directors with respect to the corporate accounting and financial reporting processes, systems of internal control and financial

#### Compensation Committee
The compensation committee currently consists of Alissa M. Fitzgerald, Ray Johnson and Thomas J. Iannotti. The chair of the compensation committee is Dr. Johnson. The Board of Directors has determined that each member of the compensation committee is independent under the Nasdaq listing standards and Rule 10C-1 of the Exchange Act, and a "non-employee director" as defined in Rule 16b-3 promulgated under the Exchange Act. From March 2022 until July 2025, Michael Clifton served on the compensation committee, and the Board of Directors had also determined that Mr. Clifton was independent under the Nasdaq listing standards and Rule 10C-1 of the Exchange Act, and a "non-employee director" as defined in Rule 16b-3 promulgated under the Exchange Act.

The primary purpose of the compensation committee is to discharge the responsibilities of the Board of Directors in overseeing the compensation policies, plans and programs and to review and determine the compensation to be paid to executive officers, directors and other senior management, as appropriate. Specific responsibilities of the compensation committee include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reviewing and determining the compensation to be paid to our directors, executive officers and other senior management, as appropriate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • helping the Board of Directors oversee our compensation policies, plans and programs with a goal to attract, incentivize, retain and reward top quality executive management and employees;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • when required, reviewing and discussing with management our compensation disclosures in our annual reports, registration statements, proxy statements or information statements filed with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • when required, preparing and reviewing the compensation committee report on executive compensation for our annual proxy statements, as applicable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reviewing and ensuring our talent management strategies are aligned to best practices and ensure we attract, retain, and develop top talent.

 *Compensation Committee Processes and Procedures* 

The compensation committee generally meets quarterly and with greater frequency if necessary. The compensation committee also acts periodically by unanimous written consent in lieu of a formal meeting. The agenda for each meeting is usually developed by the chairperson of the compensation committee, in consultation with management. The compensation committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the compensation committee to make presentations, to provide financial or other background information or advice or to otherwise participate in compensation committee meetings. Our Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the compensation committee regarding his compensation.

The charter of the compensation committee grants the compensation committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the compensation committee has the authority to obtain, at our expense, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the compensation committee considers necessary or appropriate in the performance of its duties. The compensation committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the compensation committee. In particular, the compensation committee has the authority to retain compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant's reasonable fees and other retention terms.

The chairperson of the compensation committee shall have the delegated authority to act on behalf of the compensation committee in connection with the approval of the retention of compensation consultants and outside service providers and advisors (including negotiation and execution of their engagement letters), and as may otherwise be determined by the compensation committee. The compensation committee also may form subcommittees consisting of one or more of its members for any purpose that the compensation committee deems appropriate and may delegate to such subcommittee such power and authority of the

------

[**TABLE OF CONTENTS**](#TOC)

compensation committee as the compensation committee deems appropriate; provided, however, that when appropriate to satisfy the requirements of Section 16b-3 of the Exchange Act, any such subcommittee shall be composed solely of two or more members that have been determined to be "Non-Employee Directors" within the meaning of Rule 16b-3 under the Exchange Act. By delegating an issue to the chairperson or a subcommittee, the compensation committee does not surrender any authority over that issue. Although the compensation committee may act on any issue that has been delegated to the chairperson or a subcommittee, doing so will not limit or restrict future action by the chairperson or subcommittee on any matters delegated to it. The compensation committee may delegate to one or more officers of the Company the authority to make grants and awards of cash or options or other equity securities to any non-executive officer (as defined below) of the Company under the Company's incentive-compensation or other equity-based plans as the compensation committee deems appropriate and in accordance with the terms of such plan; provided that such delegation is in compliance with the plan and the laws of the state of the Company's jurisdiction. In the event of such delegation, at each meeting of the compensation committee, the delegated officer(s) shall report to the compensation committee the awards made since the prior meeting.

In November 2025, at the recommendation of the compensation committee, our Board of Directors established the Equity Award Committee for the purpose of the Board of Directors delegating authority to the Equity Award Committee pursuant to the 2022 Plan to make grants of RSU awards to certain new hire non-executive employees of the Company. See "—Equity Award Committee" below for more information.

In 2025 and 2024, the compensation committee engaged Compensia, Inc. ("***Compensia***") as an independent compensation consultant to evaluate the efficacy and design of the Company's existing compensation strategy and practices in supporting and reinforcing the Company's long-term strategic goals and to assist in refining the Company's compensation strategy and in developing and implementing an executive compensation program to execute that strategy as well as the Company's director compensation program.

As part of its engagement, Compensia was requested by the compensation committee to develop a comparative group of companies and to perform analyses of competitive performance and compensation levels for that group. Compensia ultimately developed recommendations that were presented to the compensation committee for its consideration.

The compensation committee continued to engage Compensia in 2025 to provide advice with respect to the design of our director, executive officer and employee compensation programs as well as the compensation of each of our executive officers. The compensation committee has analyzed whether the work of Compensia as its compensation consultant raised any conflict of interest, considering relevant factors in the applicable rules, and determined that its work did not raise any conflict of interest.

For executives other than our Chief Executive Officer, the compensation committee solicits and considers evaluations and recommendations submitted to the committee by our Chief Executive Officer. The evaluation of our Chief Executive Officer's performance is conducted by the compensation committee, which determines any adjustments to his compensation as well as awards to be granted. For all executives and directors, as part of its deliberations, the compensation committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current company-wide compensation levels and recommendations of the compensation committee's compensation consultant, including analyses of executive and director compensation paid at other companies identified by the consultant.

For the fiscal years ended December 31, 2024 and 2025, the compensation committee established an annual performance-based cash bonus program, pursuant to which executive officers may earn annual bonuses based upon specified corporate performance objectives. See "Narrative Disclosure to Summary Compensation Table—2025 Non-Equity Incentive Plan Compensation" for a description of our performance-based cash bonus program.

#### Nominating and Corporate Governance Committee
The nominating and corporate governance committee currently consists of Thomas J. Iannotti, H. Gail Sandford and Michael Clifton. The chair of the nominating and corporate governance committee is

------

[**TABLE OF CONTENTS**](#TOC)

Ms. Sandford. Following the expiration of Ms. Sandford's term as a director at the Annual Meeting, Mr. Iannotti will become the chair of the nominating and corporate governance committee. The Board of Directors has determined that each member of the nominating and corporate governance committee is independent under the Nasdaq listing standards. From March 2022 until July 2025, Alissa M. Fitzgerald served on the nominating and corporate governance committee, and the Board of Directors had also determined that Dr. Fitzgerald was independent under the Nasdaq listing standards.

Specific responsibilities of the nominating and corporate governance committee include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • overseeing, and advising the Board of Directors with respect to, our corporate governance functions and developing, updating as necessary and recommending to the Board of Directors the governance principles applicable to the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • identifying, evaluating and recommending and communicating with candidates qualified to become Board of Directors members or nominees for directors of the Board of Directors consistent with criteria approved by the Board of Directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • making other recommendations to the Board of Directors relating to the directors of the Company, including identification of directors qualified to serve on the various committees of the Board of Directors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • overseeing succession planning for the Chief Executive Officer and other executive officers.

The nominating and corporate governance committee believes that candidates for director should have certain minimum qualifications, including the highest personal integrity and ethics, the ability to read and understand basic financial statements and being older than 21. The nominating and corporate governance committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to our affairs, demonstrated excellence in his or her field, having the ability to exercise sound business judgment, experience as a Board of Directors member or executive officer of another publicly held company, having a varied perspective and professional experience, having the commitment to rigorously represent the long-term interests of our stockholders, having the interest and ability to understand the sometimes conflicting interests of the various constituencies of our company, and to act in the interests of our stockholders, and should not have, nor appear to have, a conflict of interest that would impair the nominee's ability to represent the interests of our stockholders and to fulfill the responsibilities of a director. These qualifications may be modified from time to time. Candidates for director nominees are reviewed in the context of the current composition of the Board of Directors, our operating requirements and the long-term interests of our stockholders. In conducting this assessment, the nominating and corporate governance committee typically considers personal and professional background, skills and other factors as it deems appropriate, given the current needs of the Board of Directors and our business, to maintain a balance of knowledge, experience and capability.

In the case of incumbent directors whose terms of office are set to expire, the nominating and corporate governance committee reviews these directors' overall service to the Company during their terms, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair the directors' independence. In the case of incumbent directors and new director candidates, our nominating and corporate governance committee also evaluates whether the nominee is independent for Nasdaq purposes, based upon applicable Nasdaq listing standards, and applicable SEC rules and regulations. In identifying director candidates, our nominating and corporate governance committee may seek referrals from other members of the Board of Directors, management, stockholders and other sources. Our nominating and corporate governance committee may, but need not, retain a third-party search firm to assist in identifying director candidates. Our nominating and corporate governance committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of our Board of Directors. Our nominating and corporate governance committee meets to discuss and consider the candidates' qualifications and then selects a nominee for recommendation to our Board of Directors.

In 2026, our nominating and corporate governance committee evaluated the qualifications of Dr. Subodh Kulkarni in accordance with the criteria described above. Our Board of Directors believes that its current membership, including Dr. Kulkarni, the director nominated for re-election as a Class I director at the Annual

Meeting, provides an appropriate balance of knowledge, experience and capability given the current needs of the Board of Directors and our business.

#### Equity Award Committee
In November 2025, at the recommendation of the compensation committee, our Board of Directors established an equity award committee of the Board (the "***Equity Award Committee***") consisting of Dr. Subodh Kulkarni, in his capacity as a member of the Board of Directors, to delegate authority pursuant to the 2022 Plan to make grants of RSU awards to certain new employees of the Company who are not executive officers, subject to limitations approved by the Board of Directors. The purpose of this delegation of authority is to enhance the flexibility of equity award administration within the Company and to facilitate the timely grant of RSU awards to new, non-management employees, within specified limits recommended by the compensation committee and approved by the Board of Directors. During the fiscal year ended December 31, 2025, the Equity Award Committee did not grant any RSUs to new non-executive officer employees of the Company.

#### Communications with Our Board of Directors
We have adopted a written policy for stockholder communications with our Board of Directors. Our relationship with our stockholders is an important part of our corporate governance program. Engaging with stockholders helps us to understand how they view us, to set goals and expectations for our performance, and to identify emerging issues that may affect our strategies, corporate governance, compensation practices or other aspects of our operations. Our stockholder and investor outreach includes analyst meetings, investor conferences and meetings with stockholders. We also communicate with stockholders and other stakeholders through various media, including our annual report and SEC filings, news releases and our website. Our webcasts for quarterly earnings releases are open to all. These webcasts are available in real time and are archived on our website for a period of time.

Our nominating and corporate governance committee will consider stockholder recommendations of director candidates, so long as they comply with applicable law and the notice procedures for nominations of director candidates set forth in our Bylaws, which procedures are summarized below and will review the qualifications of any such candidate in accordance with the criteria described in the two preceding paragraphs. Stockholders who wish to recommend individuals for consideration by our nominating and corporate governance committee to become nominees for election to our Board of Directors should do so by delivering a written recommendation to our nominating and corporate governance committee at 775 Heinz Avenue, Berkeley, CA 94710, Attention: Corporate Secretary. See "When are stockholder proposals and director nominations due for next year's annual meeting?" for information regarding the requirements for submitting any such recommendation. For additional information about our director nomination requirements, please see our Bylaws.

Stockholders wishing to communicate with our Board of Directors or an individual director may send a written communication to the Board or such director c/o Rigetti Computing, Inc., 775 Heinz Avenue, Berkeley, CA 94710, Attn: Corporate Secretary. Each communication must set forth: (i) the name and address of the stockholder on whose behalf the communication is sent; and (ii) the number and class of shares of the Company that are owned beneficially by such stockholder as of the date of the communication. The Corporate Secretary will review each communication. The Corporate Secretary will forward such communication to the Board or to any individual director to whom the communication is addressed unless the communication contains advertisements or solicitations or is unduly hostile, threatening or similarly inappropriate, in which case the Corporate Secretary shall discard the communication.

#### Code of Business Conduct and Ethics
The Board of Directors has adopted a Code of Business Conduct and Ethics (the "***Code of Conduct***") applicable to all of our employees, officers and directors. The Code of Conduct is available at the investors section of our website at https://investors.rigetti.com/corporate-governance/overview. Any amendments to the Code of Conduct, or any waivers of its requirements, are expected to be disclosed on our website at the above location to the extent required by applicable rules and exchange requirements, including in order to

------

[**TABLE OF CONTENTS**](#TOC)

satisfy Item 5.05 of Form 8-K. The reference to our website address here and elsewhere in this proxy statement does not constitute incorporation by reference of the information contained at or available through our website.

#### Corporate Governance Guidelines
Our Board of Directors has adopted the Rigetti Computing, Inc. Corporate Governance Guidelines for the conduct and operation of the Board of Directors in order to give directors a framework for effectively pursuing our objectives for the benefit of our stockholders. The Corporate Governance Guidelines set forth the practices the Board of Directors intends to follow with respect to Board of Directors composition and selection, Board of Directors meetings and involvement of senior management, Chief Executive Officer performance evaluation and management succession planning and Board of Directors committees and compensation. The Corporate Governance Guidelines are available in the investors section of our website at https://investors.rigetti.com/corporate-governance/overview.

#### Insider Trading and Hedging Policy
Our Board of Directors has adopted an insider trading policy governing the purchase, sale and/or other dispositions of our securities by our directors, officers and employees that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations, and any applicable listing standards. A copy of our insider trading policy is incorporated by reference as Exhibit 19 to the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2025. Our insider trading policy also prohibits hedging or monetization transactions with respect to our securities, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds. In addition, our insider trading policy prohibits trading in derivative securities related to our securities, which include publicly traded call and put options, engaging in short selling of our securities, purchasing our securities on margin or holding it in a margin account and pledging our shares as collateral for a loan.

#### Incentive Compensation Recoupment Policy
The compensation committee has adopted an Incentive Compensation Recoupment Policy (the "***Clawback Policy***") for recoupment of incentive compensation in accordance with SEC requirements and Nasdaq listing standards. The Clawback Policy provides for the repayment of any incentive compensation paid to our current or former executive officers ("***Covered Officers***"), where the payments were granted, earned or vested in whole or in part on the attainment of a financial reporting measure and the Company is being required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under applicable securities laws. The Clawback Policy applies to incentive compensation received by a covered officer on or after October 2, 2023.

#### Policies and Practices Related to the Grant of Certain Equity Awards
We do not have any formal written policy that requires us to grant, or avoid granting, equity-based compensation to our executive officers and directors at certain times. In all cases, the timing of grants of equity awards, including stock options and RSUs, occurs independent of the release of any material nonpublic information, and we do not time the disclosure of material nonpublic information for the purpose of affecting the value of equity-based compensation. It is our practice to grant equity awards, including stock options and RSUs, to employees during open trading windows. In 2025, no named executive officer was granted stock options during any period beginning four business days before, and ending one business day after, the filing of a periodic report on Form 10-Q or annual report on Form 10-K, or the filing or furnishing of a current report on Form 8-K that disclosed material nonpublic information.

#### PROPOSAL 2

#### RATIFICATION OF BDO USA, P.C. AS THE COMPANY'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2026
The Audit Committee of our Board of Directors has appointed BDO USA, P.C. ("***BDO***") as our independent registered public accounting firm for the fiscal year ending December 31, 2026 and has further recommended that our Board of Directors direct management to submit the appointment of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting and recommend that stockholders vote for such ratification. BDO has audited our financial statements since 2021. Representatives of BDO are expected to be present at the Annual Meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require stockholders' ratification of the appointment of BDO as our independent registered public accounting firm. However, the Board of Directors is submitting the appointment of BDO to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the appointment, the Audit Committee of our Board of Directors will reconsider whether or not to retain that firm. Even if the appointment is ratified, the Audit Committee of our Board of Directors in its discretion may appoint different independent auditors at any time during the year if they determine that such a change would be in the best interests of Rigetti and our stockholders.

#### Principal Accountant Fees and Services
The following tables present the aggregate fees billed by BDO for the fiscal years ended December 31, 2025 and 2024.

<sup>(1)</sup>

Audit fees in each of 2025 and 2024 consisted of fees billed for professional services rendered for the audits of the Company's consolidated financial statements, reviews of the interim condensed consolidated financial statements, and audit services provided in connection with other regulatory filings and offerings, and related financings.

All fees were pre-approved by our audit committee.

#### Pre-Approval Policies and Procedures
We have adopted a written policy and procedures for the pre-approval of audit and non-audit services rendered by the Company's independent registered public accounting firm. Our audit committee (or its delegate) pre-approves all audit and all permitted non-audit services provided by BDO before it is engaged by us to render services to ensure that the provision of these services does not impair the auditor's independence. These non-audit services may include audit-related services, tax services, and other non-audit services.

The pre-approval requirement set forth above does not apply with respect to any permissible non-audit services if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all such services do not, in the aggregate, amount to more than 5% of the total fees paid by us to BDO during the fiscal year in which the services are provided;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • such services were not recognized as non-audit services at the time of the relevant engagement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • such services are promptly brought to the attention of and approved by the audit committee (or its delegate) prior to the completion of the annual audit.

The audit committee elected to delegate pre-approval authority to the chair of the audit committee to approve any one or more individual permitted non-audit services, with any pre-approval granted by the chair of the audit committee to be reported at the next meeting of the audit committee.

#### EXECUTIVE AND DIRECTOR COMPENSATION

#### Emerging Growth Company Status
We qualify as an "emerging growth company" under the Jumpstart Our Business Startups Act of 2012. As a result, we are permitted to and rely on exemptions from certain disclosure requirements that are applicable to other companies that are not emerging growth companies. Accordingly, we have included compensation information for only our principal executive officer and our two next most highly compensated executive officers serving at fiscal year-end and have not included a compensation discussion and analysis of our executive compensation programs or tabular compensation information other than the Summary Compensation Table and the Outstanding Equity Awards table. In addition, for so long as we are an emerging growth company, we will not be required to submit certain executive compensation matters to our stockholders for advisory votes, such as "say-on-pay" and "say-on-frequency" of say-on-pay votes.

We will remain an emerging growth company under the JOBS Act until the earliest of (a) December 31, 2026, (b) the last date of our fiscal year in which we have a total annual gross revenue of at least $1.235 billion, (c) the date on which we are deemed to be a "large accelerated filer" under the rules of the SEC or (d) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the previous three years.

Under the current rules of the SEC, we will no longer be eligible to take advantage of the scaled disclosures available to "smaller reporting companies" beginning with our Quarterly Report on Form 10-Q for the first quarter of 2026.

#### Executive Compensation
For the fiscal year ended December 31, 2025, our named executive officers were:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Dr. Subodh Kulkarni, President and Chief Executive Officer;

#### Employment Arrangements with Named Executive Officers
Each of Dr. Kulkarni, Mr. Rivas and Mr. Bertelsen are at-will employees. Except as set forth below, as of the date of this proxy statement, we have not entered into any employment agreements or offer letters with our named executive officers.

 *Dr. Subodh Kulkarni* 

In December 2022, we entered into an executive employment agreement with Dr. Kulkarni pursuant to which he receives an annual base salary and is eligible to participate in the Company's benefit plans and receive stock options, restricted stock, restricted stock units or other equity awards. Dr. Kulkarni is also eligible to receive an annual discretionary bonus, subject to review and adjustment by the Board of Directors or the compensation committee and the achievement of applicable performance targets and goals. Dr. Kulkarni is also entitled to certain severance benefits as described below in "—Potential Payments Upon Termination or Change in Control."

 *David Rivas* 

In March 2023, we entered into an amended and restated executive employment agreement with Mr. Rivas in connection with his promotion to Chief Technology Officer of the Company (from Senior Vice President, Systems and Services) on February 9, 2023. Pursuant to the amended and restated executive employment agreement, Mr. Rivas receives an annual base salary and is eligible to participate in the Company's benefit plans and receive stock options, restricted stock, restricted stock units or other equity awards. Mr. Rivas is also eligible to receive an annual discretionary bonus, subject to review and adjustment by the Board of Directors or the compensation committee and the achievement of applicable performance targets and goals. Mr. Rivas is also entitled to certain severance benefits as described below in "—Potential Payments Upon Termination or Change in Control."

 *Jeffrey Bertelsen* 

In February 2023, we entered into an executive employment agreement with Mr. Bertelsen pursuant to which he receives an annual base salary and is eligible to participate in the Company's benefit plans and receive stock options, restricted stock, restricted stock units or other equity awards. Mr. Bertelsen is also eligible to receive an annual discretionary bonus, subject to review and adjustment by the Board of Directors or the compensation committee and the achievement of applicable performance targets and goals.

#### Annual Base Salary
The Compensation Committee reviews and determines the compensation to be paid to our named executive officers. Annual base salaries are intended to provide a fixed component of compensation to our named executive officers, reflecting their skill sets, experience, roles and responsibilities. Base salaries for our named executive officers have generally been set at levels necessary to attract and retain individuals with superior talent.

The following table sets forth the annual base salaries for each of our named executive officers for 2025:

---

| | |
|:---|:---|
| **Name**  | **2025 Base Salary**  |

[**TABLE OF CONTENTS**](#TOC)

#### Non-Equity Incentive Plan Compensation
 *Annual Performance-Based Cash Bonus Program* 

We have established an annual performance-based cash bonus program for our executive officers, including our named executive officers, and certain other key employees (the "***Executive Bonus Plan***"). The Executive Bonus Plan is funded based on the satisfaction of corporate performance objectives established by the compensation committee and the Board of Directors at the beginning of the year. Following the end of the year, the compensation committee in its discretion determines and certifies the Company's performance against these goals and the resulting funding level of the Executive Bonus Plan. Each named executive officer and other key management employees have a target annual incentive opportunity, subject to annual review and adjustment, calculated as a percentage of annual base salary, and may earn more or less than the target amount based on our Company's performance.

For Mr. Rivas and Mr. Bertelsen, each of their executive employment agreements specifies that his annual cash bonus target shall be equal to 25% of his then-current base salary, subject to review and adjustment by the Company. For 2025, the Board of Directors approved an annual cash bonus target of 25% of his then-current base salary for each of Mr. Rivas and Mr. Bertelsen. Dr. Kulkarni's employment agreement provided for an initial annual cash bonus target equal to $290,000, which was slightly less than 50% of his then-current base salary, subject to review and adjustment by the Company. For 2025, the Board of Directors approved an annual cash bonus target of 50% of Dr. Kulkarni's base salary for 2025.

In determining the actual individual Executive Bonus Plan payouts, the compensation committee may also exercise its discretion to increase or reduce the bonuses actually paid under the Executive Bonus Plan above or below the level of attainment of our corporate performance objectives used to determine the funding of the Executive Bonus Plan. However, in no event can aggregate payments under the Executive Bonus Plan exceed the amount by which the Executive Bonus Plan is funded. Per the Executive Bonus Plan, the bonus is funded based upon the product of (a) the participants' bonus target percentage multiplied by their bonus year base pay and (b) the final payout rate calculated based upon achievement of the pre-specified goals.

 *2025 Performance Objectives* 

For fiscal year 2025, the Executive Bonus Plan provided that the Executive Bonus Plan pool would be funded based on the Company's achievement of 100+ qubit median 2-qubit (2Q) fidelity improvements with iSWAP or CZ type gates using industry standard measurement methods, as set forth in more detail below:

Median 2Q Fidelity with iSWAP or CZ Type Gate (using industry standard measurement methods) with over 100+ qubits

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • Below 99.2% median 2-qubit fidelity: no bonus amount is due;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • At or above 99.2% median 2-qubit fidelity and below 99.5% median 2-qubit fidelity: 50% of target bonus is due;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • At or above 99.5% median 2-qubit fidelity and below 99.7% median 2-qubit fidelity: 100% of target bonus is due (target); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • At or above 99.7% median 2-qubit fidelity: 150% of target bonus is due (maximum).

For performance that falls between the levels set forth above, the achievement factor will be determined by linear extrapolation.

 *2025 Results of Performance Objectives* 

As of the end of fiscal year 2025, the Company did not achieve the 2025 performance objectives required to fund the Executive Bonus Plan pool per the above criteria; as a result, the Executive Bonus Plan pool was not funded and no bonus amounts were awarded to our named executive officers for fiscal year 2025.

#### Equity-Based Incentive Awards
Our equity award program is the primary vehicle for offering long-term incentives to our executives. We believe that equity awards provide our executive officers with a strong link to long-term performance, create an

------

[**TABLE OF CONTENTS**](#TOC)

ownership culture and help to align the interests of Rigetti's executive officers and stockholders. To date, we have historically granted stock options, both incentive stock options and non-statutory stock options, RSUs and stock awards to our executive officers. We believe that our equity awards are an important retention tool for our executive officers, as well as for our other employees. We grant equity awards broadly to our employees, including to our non-executive employees. The compensation committee and/or our Board of Directors is responsible for approving equity grants.

All options are granted with an exercise price per share that is no less than the fair market value of our Common Stock on the date of grant.

In November 2025, after receiving input from Compensia, the compensation committee recommended to the Board of Directors, and the Board of Directors subsequently approved, the following methodology to determine the number of shares of Common Stock underlying annual grants of RSU awards to be granted to employees of the Company, including our named executive officers by dividing the dollar value of the RSU award by the average closing stock price of our Common Stock, as reported on the Nasdaq Capital Market (or such other primary U.S. exchange for our Common Stock if not the Nasdaq Capital Market), for the trailing 60-trading day period ending on, and including, the date that is one trading day prior to the date of grant of such RSU award, rounded down to the nearest whole share. The purpose of utilizing a 60-trading day period, rather than a single day stock price on the date of grant, is to mitigate the impact of any short-term stock price volatility on the number of RSUs granted. The compensation committee and the Board understand that this process can result in the ultimate grant date value of an RSU award as required to be reported in the Summary Compensation Table under ASC Topic 718 being higher or lower than the RSU award value under the 60-trading day methodology, but have considered, in consultation with Compensia, various approaches to granting RSU awards, each of which has advantages and disadvantages, and determined that the process described above is the most appropriate for the Company at this time. As this methodology became effective for RSU awards granted after November 2025, the number of shares of Common Stock underlying the RSU awards granted in March 2025 to Mr. Rivas and Mr. Bertelsen were not determined pursuant to this updated methodology.

 *Equity-Based Incentive Awards Granted in 2025* 

On March 10, 2025, Mr. Rivas was granted an RSU for 200,000 shares of our Common Stock, with 1/16<sup>th</sup> of the RSUs vesting on the 20<sup>th</sup> day of the middle month of each quarter (i.e., February 20, May 20, August 20 and November 20) commencing on May 20, 2025, subject to Mr. Rivas' continuous service through each such vesting date.

On March 10, 2025, Mr. Bertelsen was granted an RSU for 200,000 shares of our Common Stock, with 1/16<sup>th</sup> of the RSUs vesting on the 20<sup>th</sup> day of the middle month of each quarter (i.e., February 20, May 20, August 20 and November 20) commencing on May 20, 2025, subject to Mr. Bertelsen's continuous service through each such vesting date.

During 2025, the compensation committee aligned the timing of equity-based incentive awards such that annual grants for all employees including executive officers will be awarded during the first quarter of each fiscal year starting in 2026; as a result, Dr. Kulkarni, who received a stock option grant in November 2024, did not receive an equity-based incentive award during fiscal year 2025.

#### Health and Welfare and Retirement Benefits; Perquisites
All of the Company's named executive officers are eligible to participate in the Company's employee benefit plans, including medical, dental, vision, disability and life insurance plans, in each case on the same basis as all of the Company's other full-time employees. We pay the premiums for medical, dental, vision, group term life, disability and accidental death and dismemberment insurance for all of our employees, including our named executive officers. We generally do not provide perquisites or personal benefits to our named executive officers, except in limited circumstances.

#### 401(k) Plan
Our named executive officers are eligible to participate in a defined contribution retirement plan (the "***401(k) plan***") that provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Eligible employees may defer eligible compensation on a pre-tax or after-tax (Roth) basis, up to the statutorily prescribed annual limits on contributions under the Internal Revenue Code of 1986, as amended (the "***Code***"). Contributions are allocated to each participant's individual account and are then invested in selected investment alternatives according to the participant's directions. The 401(k) plan is intended to be qualified under Section 401(a) of the Code with the 401(k) plan's related trust intended to be tax exempt under Section 501(a) of the Code. As a tax-qualified retirement plan, contributions to the 401(k) plan (except for Roth contributions) and earnings on those contributions are not taxable to the employees until distributed from the 401(k) plan.

#### Potential Payments Upon Termination or Change in Control
Each of Dr. Kulkarni, Mr. Rivas and Mr. Bertelsen is entitled to certain severance benefits pursuant to his respective employment agreement.

In the event that employment is terminated by Rigetti without "Cause" or by the named executive officer for "Good Reason" (each, as defined in the respective executive employment agreement) and provided such named executive officer timely executes and does not revoke a release of claims in Rigetti's favor, Dr. Kulkarni, Mr. Rivas or Mr. Bertelsen, as the case may be, is entitled to: (a) continuing payments of his then-current annual base salary for twenty-four months (for Dr. Kulkarni) or twelve months (for Mr. Rivas and Mr. Bertelsen); (b) for Mr. Rivas and Mr. Bertelsen, payment of the premiums necessary to continue health insurance coverage for himself and his eligible dependents under Rigetti's group health plans pursuant to COBRA or similar state insurance laws ("COBRA Benefits"), for up to twelve months or, for Dr. Kulkarni, a lump sum cash amount equal to twenty-four months of the COBRA Benefits; (c) for Dr. Kulkarni, a cash payment equal to two times his full target amount of his annual cash bonus, payable in two installments (the first in a lump sum payment on his date of termination and the second payment occurring twelve months thereafter); (d) for Dr. Kulkarni, the time-based vesting conditions applicable to 100% of his then-outstanding stock options and/or other equity awards subject to time-based vesting requirements as of his termination date shall be accelerated as of the date of termination; and (e) his "accrued obligations" (as defined in the respective executive employment agreement), which include such executive's accrued but unpaid salary through the date of termination (and, for Dr. Kulkarni, his accrued but unused vacation, in the event Rigetti has adopted an accrual vacation policy), unreimbursed business expenses, and benefits owed to such named executive officer under retirement or health plans in which such named executive officer was a participant.

If the named executive officer's employment is terminated by Rigetti other than for "Cause," death or disability or by the named executive officer for "Good Reason" within three months prior to or twelve months after a Change in Control (as defined in the 2022 Plan), and provided such named executive officer timely executes and does not revoke a release of claims in Rigetti's favor, Dr. Kulkarni, Mr. Rivas or Mr. Bertelsen, as the case may be, is entitled to, in lieu of and not in addition to any other severance benefit: (a) the time-based vesting conditions applicable to 100% of his then-outstanding stock options and/or other equity awards subject to time-based vesting requirements as of his termination date shall be accelerated as of the date of termination

[**TABLE OF CONTENTS**](#TOC)

(and, for Mr. Rivas and Mr. Bertelsen, with respect to any performance-based equity awards, and unless otherwise provided by the applicable award agreement, any performance-based vesting objectives will be deemed achieved at the higher of target or actual performance); (b) a lump sum cash payment equal to two times his then-current annual base salary (for Dr. Kulkarni) or his then-current annual base salary (for Mr. Rivas and Mr. Bertelsen); (c) for Mr. Rivas and Mr. Bertelsen, payment of the COBRA Benefits for up to twelve months or, for Dr. Kulkarni, a lump sum cash amount equal to twenty-four months of the COBRA Benefits; and (d) for Dr. Kulkarni, a lump sum amount equal to two times his full target amount of his annual cash bonus, and for Mr. Rivas and Mr. Bertelsen, a lump sum amount equal to a pro rata share of his full target amount of his annual cash bonus, for the portion of the performance year completed when his termination occurs.

Under each of the named executive officer's employment agreement, "Cause" means that we have determined in our sole discretion that the named executive officer has engaged in any of the following: (i) his material breach of any covenant or condition under the executive employment agreement or any other agreement between the parties, and, to the extent curable, such named executive officer has not cured such breach after the expiration of ten (10) days after written notice from us of such breach; (ii) his material act constituting dishonesty or fraudulent conduct in connection with his duties to us; (iii) any conduct which constitutes a felony or a crime of moral turpitude under applicable law; (iv) material violation of any Company policy and, to the extent curable, such named executive officer has not cured such violation after the expiration of ten (10) days after written notice from us of such violation; (v) refusal to follow or implement a clear and reasonable directive of the Company, or any act of willful or intentional misconduct in relation to the named executive officer's duties to the Company; (vi) repeated or willful failure by the named executive officer to perform his duties in a manner satisfactory to the Company after the expiration of ten (10) days without cure after written notice of such failure; or (vii) his breach of fiduciary duty to the Company.

Under each named executive officer's employment agreement, "Good Reason" means the occurrence of any of the following events without such named executive officer's consent: (i) a material reduction in his base salary, other than a reduction applied in a similar proportional amount to all similarly situated executives; (ii) a material breach of the executive employment agreement by Rigetti; (iii) a material reduction in his duties, authority and responsibilities relative to the his duties, authority, and responsibilities in effect immediately prior to such reduction; (iv) for Dr. Kulkarni and Mr. Bertelsen, a material change in his reporting relationship, other than such change made directly in connection with organizational changes resulting from a "Change in Control" (as defined in the respective employment agreement); or (v) the relocation of his principal place of employment, without his consent, in a manner that lengthens his one-way commute distance by twenty-five (25) or more miles from his then-current principal place of employment immediately prior to such relocation. Any such termination by such named executive officer shall only be deemed for "Good Reason" if: (1) such named executive officer gives Rigetti written notice of his intent to terminate for Good Reason within thirty (30) days following the first occurrence of the condition(s) that he believes constitute(s) Good Reason, which notice shall describe such condition(s); (2) Rigetti fails to remedy such condition(s) within thirty (30) days following receipt of the written notice (the "***Cure Period***"); and (3) such named executive officer voluntarily terminates employment within thirty (30) days following the end of the Cure Period, or the parties agree in writing to extend such Cure Period.

#### Non-Employee Director Compensation Policy

All annual cash fees are vested upon payment. If an Eligible Director terminates service on the Board of Directors or a committee during the course of a fiscal quarter, the annual retainer amount for the fiscal quarter in which such termination occurs will be prorated based on days served in such fiscal quarter.

#### Equity Compensation
All grants of equity awards to Eligible Directors pursuant to this Non-Employee Director Compensation Policy will be nondiscretionary, automatic (without the need for any additional corporate action by the Board of Directors or the compensation committee) except as otherwise provided below and made in accordance with the following provisions. The equity compensation set forth above will be granted subject to the terms and conditions of the 2022 Plan and an applicable award agreement.

In 2024 and prior to April 1, 2025, the Non-Employee Director Compensation Policy provided for an initial grant of RSUs with a fair market value on the grant date equal to $210,000 (the "***Initial RSU Grant***") to each Eligible Non-Employee Director not serving as Chair of the Board of Directors, and for the Eligible Non-Employee Director serving as the Chair of the Board of Directors, an option to purchase shares of Common Stock with a fair market value on the grant date equal to $1,000,000 (the "***Initial Option Grant***"); subject to a maximum of 720,000 shares of Common Stock. The Initial RSU Grant and the Initial Option Grant will vest over a three-year period, with one-third (1/3) of the grant vesting on the first anniversary of the grant date, one-third (1/3) of the grant vesting on the second anniversary of the grant date and the remaining one-third (1/3) of the grant vesting on the third anniversary of the grant date, such that the grant is fully vested on the third anniversary of the date of grant, subject to the Eligible Director's continuous service through each such vesting date.

In 2024 and prior to April 1, 2025, the Non-Employee Director Compensation Policy also provided for annual grants of RSUs with a fair market value on the grant date equal to $140,000 (the "***Annual RSU Grant***") to

------

[**TABLE OF CONTENTS**](#TOC)

each Eligible Non-Employee Director not serving as Chair of the Board of Directors, and for the Eligible Non-Employee Director serving as the Chair of the Board of Directors, an option to purchase shares of Common Stock with a fair market value on the grant date equal to $420,000 (the "***Annual Option Grant***"); provided that that the Annual Option Grant will be subject to a maximum of 140,000 shares of Common Stock. The Annual RSU Grant and the Annual Option Grant will vest in full on the earlier of (i) the date of the following year's Annual Meeting (or the date immediately prior to the next Annual Meeting if the Eligible Non-Employee Director's service as a director ends at such Annual Meeting due to the director's failure to be re-elected or the director not standing for re-election); or (ii) the one-year anniversary measured from the date of grant, in each case subject to the Eligible Director's continuous service through such vesting date.

Effective April 1, 2025, the Non-Employee Director Compensation Policy provides for an initial grant of RSUs with a fair market value on the date of grant equal to $370,000 (the "***Post***-***April 1, 2025 Initial RSU Grant***") to each Eligible Non-Employee Director upon their appointment to the Board of Directors. The Post-April 1, 2025 Initial RSU Grant will vest over a three-year period, with one-third (1/3) of the Post-April 1, 2025 Initial RSU Grant vesting on the first anniversary of the grant date, one-third (1/3) of the Post-April 1, 2025 Initial RSU Grant vesting on the second anniversary of the grant date and the remaining one-third (1/3) of the Post-April 1, 2025 Initial RSU Grant vesting on the third anniversary of the grant date, such that the Post-April 1, 2025 Initial RSU Grant is fully vested on the third anniversary of the date of grant, subject to the Eligible Director's continuous service through each such vesting date.

Effective April 1, 2025, the Non-Employee Director Compensation Policy also provides for annual grants of RSUs with a fair market value on the grant date equal to $167,500 (the "***Post***-***April 1, 2025 Annual RSU Grant***") to each Eligible Non-Employee Director. The Post-April 1, 2025 Annual RSU Grant will vest in full on the earlier of (i) the date of the following year's Annual Meeting (or the date immediately prior to the next Annual Meeting if the Eligible Non-Employee Director's service as a director ends at such Annual Meeting due to the director's failure to be re-elected or the director not standing for re-election); or (ii) the one-year anniversary measured from the date of grant, in each case subject to the Eligible Non-Employee Director's continuous service through such vesting date.

After receiving input from Compensia, the compensation committee recommended to the Board of Directors for approval, and the Board of Directors subsequently approved, an amended Non-Employee Director Compensation Policy effective as of November 25, 2025 that includes the following methodology to determine the number of shares of Common Stock underlying RSU awards to be granted to non-employee directors of the Company pursuant to the terms of the Non-Employee Director Compensation Policy: the dollar value of the RSU award divided by the average closing stock price of our Common Stock, as reported on the Nasdaq Capital Market (or such other primary U.S. exchange for our Common Stock if not the Nasdaq Capital Market), for the trailing 60-trading day period ending on, and including, the date that is one trading day prior to the date of grant of such RSU award, rounded down to the nearest whole share. The purpose of utilizing a 60-trading day period, rather than a single day stock price on the date of grant, is to mitigate the impact of any short-term stock price volatility on the number of RSUs granted. The compensation committee and the Board understand that this process can result in the ultimate grant date value of an RSU award as required to be reported in the Director Compensation Table under ASC Topic 718 being higher or lower than the RSU award value under the 60-trading day methodology, but have considered, in consultation with Compensia, various approaches to granting RSU awards, each of which has advantages and disadvantages, and determined that the process described above is the most appropriate for the Company at this time. As this methodology became effective for RSU awards granted on or after November 25, 2025, the number of shares of Common Stock underlying the RSU awards granted in June 2025 to our non-employee directors were not determined pursuant to the above methodology.

In the event of a Change in Control (as defined in the 2022 Plan), any unvested portion of the option grants and RSU grants under the Non-Employee Director Compensation Policy would vest immediately prior to the consummation of such Change in Control, subject to the Eligible Director's continuous service until immediately prior to the consummation of the Change in Control.

#### SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth information known to the Company regarding the beneficial ownership of Common Stock as of the Record Date by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • each person known by the Company to be the beneficial owner of more than 5% of outstanding shares of Common Stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • each of the Company's named executive officers and directors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all current executive officers and directors of the Company as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days.

The beneficial ownership percentages set forth in the table below are based on 332,345,548 shares of Common Stock issued and outstanding as of the Record Date. In computing the number of shares beneficially owned by a person and the percentage ownership of such person, we deemed to be outstanding all shares subject to equity awards issuable upon exercise or settlement and warrants, as applicable, held by the person that are currently exercisable or would be exercisable within 60 days of the Record Date, however we did not deem such shares outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise noted in the footnotes to the following table, and subject to applicable community property laws, the persons and entities named in the table have sole voting and investment power with respect to the securities they beneficially owned.

Percent of ownership is less than 1%

(†)

In a Schedule 13G/A filed with the SEC on January 7, 2026, The Vanguard Group ("Vanguard") reported aggregate beneficial ownership of 35,970,648 shares of Common Stock, which would constitute approximately 10.8% of all shares of Common Stock of the Company. However, in a Schedule 13G/A filed with the SEC on March 27, 2026, Vanguard reported that it beneficially owns 0.0% as of March 13, 2026, following an internal realignment pursuant to which Vanguard's beneficial ownership has been disaggregated. In its Schedule 13G/A, Vanguard noted that (i) certain subsidiaries or business divisions of subsidiaries of Vanguard that formerly had, or were deemed to have, beneficial ownership with Vanguard will report beneficial ownership separately (on a disaggregated basis) from Vanguard and (ii) that Vanguard no longer has, or is deemed to have, beneficial ownership over securities beneficially owned by such subsidiaries and/or business divisions. Accordingly, Vanguard is not included among the 5% beneficial owners presented in the table.

#### TRANSACTIONS WITH RELATED PERSONS

#### Related Person Transactions Policy
The Board of Directors adopted a written related person transactions policy that sets forth our policies and procedures regarding the identification, review, consideration and oversight of "related person transactions." For purposes of our policy only, a "related person transaction" is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which we or any of our subsidiaries are participants involving an amount that exceeds $120,000, in which any "related person" has a material interest.

Transactions involving compensation for services provided to us by an employee, consultant or director will not be considered related person transactions under this policy. A related person is any person who is, or at any time since the beginning of our last fiscal year was, an executive officer, director, or nominee to become a director, or a holder of more than 5% of any class of our voting securities (including our Common Stock), including any immediate family member and affiliate of the foregoing, as well as entities owned or controlled by any related person.

Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of our voting securities, an officer with knowledge of the proposed related person transaction, must present information regarding the proposed related person transaction to our audit committee (or, where review by our audit committee would be inappropriate, to another independent body of our Board of Directors) for review. To identify related person transactions in advance, we will rely on information supplied by our executive officers, directors and certain significant stockholders. In considering related person transactions, our audit committee will take into account the relevant available facts and circumstances, which may include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all of the parties thereto;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the interests, direct or indirect, of any related person in the transaction in sufficient detail so as to enable the audit committee (or other appropriate body, as the case may be) to fully assess such interests;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a description of the purpose of the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all of the material facts of the proposed transaction, including the proposed aggregate value of such transaction, or, in the case of indebtedness, that amount of principal that would be involved;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the benefits to the Company of the proposed transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if applicable, the availability of other sources of comparable products or services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an assessment of whether the proposed transaction is on terms that are comparable to the terms available to or from, as the case may be, an unrelated third party or to employees generally; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • management's recommendation with respect to the proposed transaction.

In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval. Our audit committee will approve only those transactions that it determines are fair to and in the best interests of the Company and its stockholders. All of the transactions described below were entered into prior to the adoption of such policy.

#### Sponsor Support Agreement
On October 6, 2021, in connection with the execution of the Merger Agreement, Supernova entered into a sponsor support agreement (the "***Sponsor Support Agreement***") with the Supernova Partners II LLC ("***Supernova Sponsor***"), Legacy Rigetti and Supernova's directors and officers. Pursuant to the Sponsor Support Agreement, the Supernova Sponsor and Supernova's directors and officers ("***Sponsor Holders***"), among other things, agreed to vote all of their shares of Supernova capital stock in favor of the approval of the Business Combination. In addition, pursuant to the Sponsor Support Agreement, (i) 2,479,000 shares of Common Stock held by the Sponsor Holders became unvested and subject to forfeiture as of the Closing and would vest only if, during the five year period following the Closing, the volume weighted average price of

------

[**TABLE OF CONTENTS**](#TOC)

Common Stock equaled or exceeded $12.50 for any 20 trading days within a period of 30 consecutive trading days, and (ii) 580,273 shares of Common Stock held by the Sponsor Holders became unvested and subject to forfeiture as of the Closing and would vest only if, during the five year period following the Closing, the volume weighted average price of Common Stock equaled or exceeded $15.00 for any 20 trading days within a period of 30 consecutive trading days. Any such shares held by the Sponsor Holders that remained unvested after the fifth anniversary of the Closing would be forfeited. The $12.50 vesting threshold was achieved in February 2025 and the $15.00 vesting threshold was achieved in August 2025; as a result, all shares held by the Sponsor Holders were vested as of December 31, 2025.

#### Amended and Restated Registration Rights Agreement
In connection with the Closing, we, Supernova Sponsor, Supernova directors and officers, Legacy Rigetti directors and officers and certain Legacy Rigetti securityholders entered into an amended and restated registration rights agreement. Pursuant to the agreement, we agreed that we would file with the SEC a registration statement registering the resale of certain securities held by or issuable to such holders, and we will use reasonable best efforts to have such registration statement declared effective as soon as practicable after the filing thereof. In certain circumstances, certain holders can demand up to two underwritten offerings in any 12-month period, and certain holders are entitled to piggyback registration rights.

#### Indemnification Agreements
We have entered into indemnification agreements with each of our directors and executive officers in addition to the indemnification provided in the Bylaws. The indemnification agreements require us to indemnify our directors and executive officers to the fullest extent permitted by Delaware law. See "Directors, Executive Officers and Corporate Governance—Limitation on Liability and Indemnification of Directors and Officers" for information about indemnification agreements and director and officer liability insurance which the Company maintains.

#### HOUSEHOLDING OF PROXY MATERIALS
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials or other Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or other Annual Meeting materials addressed to those stockholders. This process, which is commonly referred to as "householding," potentially means extra convenience for stockholders and cost savings for companies.

This year, a number of brokers with account holders who are our stockholders will likely be "householding" our proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be "householding" communications to your address, "householding" will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in "householding" and would prefer to receive a separate Notice of Internet Availability of Proxy Materials, please contact our Corporate Secretary at Rigetti Computing, Inc., 775 Heinz Avenue, Berkeley, CA 94710, or via telephone at (510) 210-5550. Stockholders who currently receive multiple copies of the Notices of Internet Availability of Proxy Materials at their addresses and would like to request "householding" of their communications should contact their brokers.

#### OTHER MATTERS
Our Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.

By Order of the Board of Directors
