PROXY STATEMENT
FOR THE SPECIAL MEETING OF STOCKHOLDERS
TO BE HELD ON JULY 27, 2026
QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING
Why am I receiving these materials?
We have sent you these proxy materials because the Board of Directors (the “Board” or “Board of Directors”) of Tempest Therapeutics, Inc. (sometimes referred to as the “Company” or “Tempest”) is soliciting your proxy to vote at a Special Meeting of Stockholders to be held on July 27, 2026 (the “Special Meeting”), including at any adjournments or postponements of the meeting. You are invited to attend the Special Meeting to vote on the proposal described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card, or follow the instructions below to submit your proxy over the telephone or through the internet.
We intend to mail these proxy materials on or about July 17, 2026 to all stockholders of record entitled to vote at the Special Meeting.
How do I attend the Special Meeting?
The Special Meeting will be held through a live webcast at www.virtualshareholdermeeting.com/TPST2026SM2. You will not be able to attend the Special Meeting in person. Stockholders attending the virtual Special Meeting will be afforded the same rights and opportunities to participate as they would at an in-person meeting.
You are entitled to attend the Special Meeting if you were a stockholder as of the close of business on May 28, 2026 (the “Record Date”), or hold a valid proxy for the meeting. To be admitted to the Special Meeting, you will need to visit www.virtualshareholdermeeting.com/TPST2026SM2 and enter the control number found next to the label “control number” included in the proxy card in the enclosed proxy materials. If you are a beneficial stockholder, you should contact the bank, broker or other institution where you hold your account well in advance of the meeting if you have questions about obtaining your control number or proxy to vote.
Whether or not you participate in the Special Meeting, it is important that you vote your shares.
The Special Meeting will begin promptly at 12:00 p.m. Eastern Time on Monday, July 27, 2026. We encourage you to access the Special Meeting a few minutes before it begins. Online check-in will start approximately 15 minutes before the meeting begins.
What if I cannot find my control number?
If you do not have your control number and you are a registered stockholder, please contact us at [email protected] and we will be able to provide your control number to you. If you do not have a control number, you will be able to login as a guest. To view the meeting webcast, visit www.virtualshareholdermeeting.com/TPST2026SM2 and register as a guest. If you login as a guest, you will not be able to vote your shares or ask questions.
If you are a beneficial owner (that is, you hold your shares in an account at a bank, broker or other holder of record), you will need to contact that bank, broker or other holder of record to obtain your control number prior to the Special Meeting.
What if I have technical difficulties or trouble accessing the virtual Special Meeting?
We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual Special Meeting. If you encounter any difficulties accessing the virtual Special Meeting during the check-in or meeting time, please call the technical support number that will be posted at www.virtualshareholdermeeting.com/TPST2026SM2.
Will a list of record stockholders as of the Record Date be available?
A list of our record stockholders as of the close of business on the Record Date will be made available to stockholders during the meeting at www.virtualshareholdermeeting.com/TPST2026SM2. In addition, for the 10 days prior to the Special Meeting, the list will be available for examination by any stockholder of record for a legally valid purpose during regular business hours. To access the list of record stockholders beginning July 17, 2026 and until the meeting, stockholders should email [email protected].

TABLE OF CONTENTS

Who can vote at the Special Meeting?
Only stockholders of record at the close of business on May 28, 2026 will be entitled to vote at the Special Meeting. On the Record Date, there were 14,806,997 shares of the Company’s common stock, par value $0.001 per share (“common stock”) outstanding and entitled to vote. Whether or not you participate in the Special Meeting, it is important that you vote your shares.
Stockholder of Record: Shares Registered in Your Name
If on the Record Date your shares were registered directly in your name with the Company’s transfer agent, Computershare Trust Company, N.A., then you are a stockholder of record. As a stockholder of record, you may vote online during the meeting or vote by proxy. Whether or not you plan to attend the Special Meeting, to ensure your vote is counted, we urge you to vote by proxy by using the enclosed proxy card, or by voting over the telephone or through the internet.
Beneficial Owner: Shares Registered in the Name of 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 these proxy materials are being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the Special Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. You are also invited to attend the Special Meeting. However, since you are not the stockholder of record, you may not vote your shares online during the meeting unless you request and obtain a valid proxy from your broker, bank or other agent.
What am I voting on?
There is one matter scheduled for a vote:
•
Approval of a Certificate of Amendment to the Company’s Restated Certificate of Incorporation to replace specified supermajority voting requirements and permit stockholder action by written consent, in the form attached as Exhibit A hereto (“CoI Amendments” or “Proposal 1”).
What if another matter is properly brought before the Special Meeting?
The Board of Directors knows of no other matters that will be presented for consideration at the Special 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 those matters in accordance with their best judgment.
How do I vote?
For the matter to be voted on, you may vote “For” or “Against” or abstain from voting.
The procedures for voting are fairly simple:
Stockholder of Record: Shares Registered in Your Name
If you are a stockholder of record, you may vote online during the Special Meeting, vote by proxy using the enclosed proxy card, vote by proxy over the telephone or vote by proxy through the internet. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote online during the meeting even if you have already voted by proxy.
•
To vote online during the meeting, access the Special Meeting materials by following the instructions you will receive in your email and submit an electronic ballot during the meeting.
•
To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the envelope provided. If you return your signed proxy card to us before the Special Meeting, we will vote your shares as you direct.
•
To vote over the telephone, dial toll-free 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the company number and control number from the enclosed proxy card. To ensure your vote is counted, your telephone vote must be received before 11:59 p.m., Eastern Time on July 26, 2026.

TABLE OF CONTENTS

•
To vote through the internet, go to www.proxyvote.com to complete an electronic proxy card. You will be asked to provide the company number and control number from the enclosed proxy card. To ensure your vote is counted, your internet vote must be received before 11:59 p.m., Eastern Time on July 26, 2026.
Beneficial Owner: Shares Registered in the Name of Broker or Bank
If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should have received a voting instruction form with these proxy materials from that organization rather than from us. Simply complete and mail the voting instruction form to ensure that your vote is counted. Alternatively, you may vote by telephone or over the internet as instructed by your broker or bank. To vote online during the Special Meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the instructions from your broker, bank or other agent included with these proxy materials, or contact that organization to request a proxy form. You must also register to attend the meeting at www.virtualshareholdermeeting.com/TPST2026SM2 using the control number as provided by your broker, bank or other agent.
Internet proxy voting will be provided to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.
How many votes do I have?
If you are a holder of our common stock, on each matter to be voted upon, you have one vote for each share of common stock you held as of the close of business on the Record Date.
If I am a stockholder of record and I do not vote, or if I return a proxy card or otherwise vote without giving specific voting instructions, what happens?
If you are a stockholder of record and do not vote by completing your proxy card, by telephone, through the internet or online during the Special Meeting, your shares will not be voted.
If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted “For” Proposal 1. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using their 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 (the “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. In this regard, Proposal 1 is considered to be “non-routine” under NYSE rules, meaning that your broker may not vote your shares on the proposal in the absence of your voting instructions.
If you are a beneficial owner of shares held in street name and you do not plan to obtain a proxy from your broker, bank or other agent and vote at the Special Meeting, in order to ensure your shares are voted in the way you would prefer, you must 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”?
A “broker non-vote” occurs when your broker submits a proxy for the meeting with respect to at least one “routine” matter but does not vote on “non-routine” matters because you did not provide voting instructions on such matters. Proposal 1 is considered non-routine under applicable stock exchange rules, and without your instruction, your broker, bank or other agent cannot vote your shares on such matter. Please instruct your broker, bank or other agent so your vote can be counted.

Who is paying for this proxy solicitation?
We will pay for the entire cost of soliciting proxies. 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.
What does it mean if I receive more than one set of proxy materials?
If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials to ensure that all of your shares are voted. In addition, we have hired Sodali & Co. (“Sodali”) to solicit proxies. We expect to pay Sodali a fee of $35,000 plus reasonable expenses for these services.
Can I change my vote after submitting my proxy?
Stockholder of Record: Shares Registered in Your Name
You can revoke your proxy at any time before the final vote at the Special Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:
•
submit another properly completed proxy card with a later date;
•
grant a subsequent proxy by telephone or through the internet;
•
send a written notice that you are revoking your proxy to our Corporate Secretary at 2000 Sierra Point Parkway, Suite 400, Brisbane, CA 94005; or
•
attend the Special Meeting and vote online. Simply attending the meeting will not, by itself, revoke your proxy.
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 your shares are held 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 Special Meeting, who will separately count “For” and “Against” votes and abstentions.
How many votes are needed to approve the proposal?

What is the quorum requirement?
A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote at the meeting are present at the meeting or represented by proxy. On the Record Date, there were 14,806,997 shares outstanding and entitled to vote. Thus, the holders of 7,403,499 shares must be present or represented by proxy at the meeting to have a quorum.

TABLE OF CONTENTS

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 vote online at the Special Meeting. Abstentions will be counted towards the quorum requirement. Broker non-votes will not be counted toward the quorum requirement. If there is no quorum, either the board of directors may postpone or reschedule the meeting or the holders of a majority of shares present at the meeting or represented by proxy may adjourn the meeting to another date. The meeting may be adjourned by the chairman of the meeting or by the stockholders present at the meeting or represented by proxy and entitled to vote.
How do I ask a question at the Special Meeting?
Only stockholders of record as of the Record Date may submit questions or comments at the Special Meeting. If you would like to submit a question, you may do so by joining the virtual meeting at www.virtualshareholdermeeting.com/TPST2026SM2 and typing your question in the box in the meeting portal.
To help 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 Special Meeting when you log in prior to the start of the Special Meeting. In accordance with the rules of conduct, we ask that you limit your questions and remarks to those that are relevant to the proposal at the Special Meeting. Our management may group questions by topic with a representative question read aloud and answered. In addition, questions may be ruled out of order if they are, among other things, irrelevant to the proposal at the Special Meeting, related to pending or threatened litigation, disorderly, repetitious of statements already made, or in furtherance of the speaker’s own personal, political or business interests.
How can I find out the results of the voting at the Special Meeting?
Preliminary voting results will be announced at the Special Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Special Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an additional Form 8-K to publish the final results.
What proxy materials are available on the internet?
The proxy statement is available at ir.tempesttx.com.

PROPOSAL 1
APPROVAL OF AN AMENDMENT TO THE CERTIFICATE OF INCORPORATION TO REPLACE SPECIFIED SUPERMAJORITY VOTING REQUIREMENTS AND PERMIT STOCKHOLDER ACTION BY WRITTEN CONSENT
General
Our Board of Directors has unanimously approved and declared advisable, and is submitting to our stockholders for approval, the CoI Amendments included in the Certificate of Amendment in the form attached to this proxy statement as Exhibit A. The CoI Amendments would amend certain provisions included in the Company’s existing certificate of incorporation, as amended to date (the “Existing CoI”), as further described in Exhibit A. The CoI Amendments are being submitted for stockholder approval pursuant to Section 242 of the Delaware General Corporation Law (the “DGCL”).
The CoI Amendments include the following changes:
•
elimination of a restriction on stockholder action by written consent, when such action is approved by holders of not less than a majority of the voting power of all outstanding shares entitled to vote thereon; and
•
replacement of specified supermajority voting provisions with majority-of-outstanding voting standards.
The Existing CoI contains certain supermajority voting provisions (including, in specified circumstances, provisions requiring the affirmative vote of the holders of at least seventy-five percent (75%) of the votes that all the stockholders would be entitled to cast in any annual election of directors or class of directors) for amendments to certain Existing CoI provisions and for certain corporate actions, including provisions proposed for amendment in Proposal 1. Therefore, approval of Proposal 1 requires the affirmative vote of the holders of at least seventy-five percent (75%) of the votes that all the stockholders would be entitled to cast in any annual election of directors or class of directors.
Reasons for Stockholder Approval
The Company operates in a competitive business environment that requires the Board to respond effectively to changing market conditions. This Proposal 1 would amend the Existing CoI to modernize and simplify the Existing CoI by permitting stockholder action by written consent and lowering several governance voting thresholds to a majority standard.
The Board believes that the supermajority provisions and existing limitations on stockholder written consent provisions included in the Existing CoI may unduly restrict stockholder participation when weighed against the stability that the provisions were intended to facilitate. The Board has carefully considered the advantages and disadvantages of maintaining such provisions and has determined that it is in the best interests of the Company and its stockholders to approve and recommend that stockholders adopt the amendments described above to revise those provisions and replace specified supermajority and governance standards with standards that the Board believes are more consistent with current governance practices of Delaware corporations.
Potential Effects of the Proposal
If this Proposal 1 is approved at the meeting, the Company plans to file a Certificate of Amendment reflecting the CoI Amendments with the Secretary of State of the State of Delaware, and it will become effective upon such filing (or such later effective time as may be specified therein), except that, by approving Proposal 1, stockholders are also authorizing the Board to abandon the CoI Amendments notwithstanding approval of Proposal 1. If this Proposal 1 is not approved, or if the Board abandons the CoI Amendments, the Company will not file the Certificate of Amendment and the Company’s Existing CoI will remain in effect.
The CoI Amendments would permit stockholder action by written consent and replace specified supermajority voting provisions with majority-of-outstanding voting standards. The Board has considered these effects and believes that the CoI Amendments, taken as a whole, are in the best interests of the Company and its stockholders.
If Proposal 1 is approved and a Certificate of Amendment reflecting the CoI Amendments is filed with the Secretary of State of the State of Delaware, the Board plans to make any required conforming changes to the Company’s bylaws.

TABLE OF CONTENTS

Additional Information
The foregoing summary is qualified in its entirety by reference to Exhibit A, which sets forth the complete text of the proposed Certificate of Amendment. Because the Certificate of Amendment would amend the Company’s Existing CoI, stockholder approval is required under the DGCL and the Company’s Existing CoI.
THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS
A VOTE IN FAVOR OF PROPOSAL 1.

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth information regarding beneficial ownership of our common stock as of May 28, 2026, the most recent practicable date for computing beneficial ownership, by:
•
each of our Named Executive Officers;
•
each of our directors and director nominees;
•
each person, or group of affiliated persons, known by us to beneficially own more than 5% of our common stock; and
•
all of our directors and executive officers as a group.
We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting or investment power with respect to those securities. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.
Applicable percentage ownership is based on 14,806,997 shares of our common stock issued and outstanding as of May 28, 2026. The number of shares of common stock used to calculate the percentage ownership of each listed person includes the shares of common stock underlying options and warrants held by such persons that are currently exercisable or convertible or will be exercisable or convertible within 60 days of May 28, 2026. However, we did not deem these shares outstanding for the purpose of computing the percentage ownership of any other person.

Stockholder proposals submitted pursuant to Rule 14a-8 under the Exchange Act, and intended to be presented at the 2026 Annual Meeting of Stockholders must be received by us not later than September 8, 2026 in order to be considered for inclusion in our proxy materials for that meeting. However, if the 2026 Annual Meeting of Stockholders is advanced by more than 30 days prior to or delayed by more than 30 days after January 27, 2027, then the deadline will be a reasonable time prior to the time we begin to print and send our proxy materials. In addition, stockholders who intend to solicit proxies in support of director nominees other than our nominees must also comply with the additional requirements of Rule 14a-19 under the Exchange Act.
Householding of Proxy Materials
The SEC has adopted rules that permit companies and intermediaries, such as brokers, to satisfy the delivery requirements for proxy statement materials with respect to two or more stockholders sharing the same address by delivering a single set of these 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.
For this meeting, a number of brokers with account holders who are our stockholders will be “householding” the Company’s proxy materials. A single set of Special Meeting 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 set of Special Meeting materials, please notify your broker or us. Direct your written request to Tempest Therapeutics, Inc., Attention: Corporate Secretary, 2000 Sierra Point Parkway, Suite 400, Brisbane, CA 94005. Stockholders who currently receive multiple copies of the Special Meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.
