We are pleased to take advantage of Securities and Exchange Commission rules that allow companies to furnish their proxy materials over the Internet. We are mailing to our stockholders a Notice of Internet Availability of Proxy Materials, or Notice, instead of a paper copy of our proxy materials and our 2024 Annual Report to Stockholders, or 2024 Annual Report.

Your vote is important. Whether or not you are able to attend the Annual Meeting in person, it is important that your shares be represented. Please vote as soon as possible, even if you plan to attend the Annual Meeting, by completing, dating, signing and returning the proxy card (if one was received), or voting over the telephone or internet as instructed in the Notice. Even if you voted by proxy, you may still vote if you attend the Annual Meeting. Please note if your shares are held of record by a broker, bank or other nominee, you must follow the instructions provided by your broker, bank or other nominee.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be Held on June 5, 2025 at 601 Marshall Street, Redwood City, California 94063: This proxy statement and our 2024 Annual Report to Stockholders are available for viewing, printing and downloading at www.proxyvote.com.

This document includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical or current facts, including statements regarding our plans and goals, made in this document are forward-looking. We use words such as anticipates, believes, expects, future, intends, and similar expressions to identify forward-looking statements. Forward-looking statements reflect management’s current expectations and are inherently uncertain. Actual results could differ materially for a variety of reasons. Risks and uncertainties that could cause our actual results to differ significantly from management’s expectations are described in our 2024 Annual Report on Form 10-K. Website references throughout this document are provided for convenience only, and the content on the referenced websites is not incorporated by reference into this document.

A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed with the Securities and Exchange Commission, except for exhibits, will be furnished without charge to any stockholder upon written request to Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attention: Secretary. This proxy statement and our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 are also available on the SEC’s website at www.sec.gov.

This proxy statement contains information about the 2025 Annual Meeting of Stockholders, or the Annual Meeting, of Astera Labs, Inc., which will be held on June 5, 2025 at 10:00 a.m. (Pacific Time). The Annual Meeting will be held at the offices of Goodwin Procter LLP at 601 Marshall Street, Redwood City, California 94063. The board of directors of Astera Labs, Inc. is using this proxy statement to solicit proxies for use at the Annual Meeting. In this proxy statement, the terms “Astera Labs,” “the Company,” “we,” “us,” and “our” refer to Astera Labs, Inc. and its consolidated subsidiaries, as appropriate. The mailing address of our principal executive offices is Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054.

We have elected to provide access to our proxy materials to our stockholders via the Internet. Accordingly, on or about April 24, 2025, we intend to begin mailing a Notice of Internet Availability of Proxy Materials, or Notice, to stockholders of record entitled to vote at the Annual Meeting.

Stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive 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.

Pursuant to rules adopted by the SEC, for most stockholders, we are providing access to our proxy materials over the Internet rather than printing and mailing our proxy materials. We believe following this process will expedite the receipt of such materials and will help lower our costs and reduce the environmental impact of printing our Annual Meeting materials.

We intend to mail the Notice to holders of record on or about April 24, 2025. The Notice provides instructions as to how stockholders may access and review our proxy materials on the website referred to in the Notice or, alternatively, how to request that a copy of the proxy materials be sent to them by mail or electronically by e-mail. There is no charge to request a copy, but in order to receive a paper package in time for the Annual Meeting, you must make the request prior to May 22, 2025.

We will pay the cost of soliciting proxies. Brokers, banks and other nominees will be requested to forward proxy soliciting material to the owners of stock held in their names, and we may reimburse them for their reasonable out-of-pocket expenses incurred in connection with the distribution of proxy materials. If you choose to access the proxy materials or vote over the Internet or via telephone, you are responsible for any Internet access charges or telephone charges that you may incur.

Our officers and employees may, without compensation other than their regular compensation, solicit proxies through further mailings, telephone, personal conversations, e-mails, or otherwise.

You are entitled to attend the Annual Meeting if you were a stockholder as of the close of business on April 15, 2025, or the Record Date. The Annual Meeting will be held on Thursday, June 5, 2025 at 10:00 a.m. Pacific Time at the offices of Goodwin Procter LLP at 601 Marshall Street, Redwood City, California 94063. Directions to the Annual Meeting may be obtained by emailing [email protected]. Information on how to vote in person at the Annual Meeting is discussed below.

The Record Date for determination of stockholders entitled to vote at the Annual Meeting is the close of business on April 15, 2025.

Only shareholders of record at the close of business on the Record Date will be entitled to vote at the Annual Meeting. If on the Record Date, your shares were registered directly in your name with our transfer agent, then you are a shareholder of record. 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 your brokerage firm, bank or other similar organization should provide you with instructions. The organization holding your account is considered to be the shareholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other nominee regarding how to vote the shares in your account.

There were 164,914,754 shares of our common stock, par value $0.0001 per share, outstanding on April 15, 2025, all of which are entitled to vote with respect to all matters to be acted upon at the Annual Meeting. Each stockholder of record is entitled to one vote for each share of our common stock held by such stockholder. No undesignated preferred stock has been issued as of the Record Date.

Our Second Amended and Restated Bylaws, or bylaws, provide that presence in person or by remote communication, if applicable, or represented by proxy, of the holders of a majority in voting power of the outstanding shares of stock entitled to vote at the Annual Meeting shall be necessary and sufficient to constitute a quorum.

Under the General Corporation Law of the State of Delaware, or DGCL, shares that are voted “abstain” or “withheld” and broker “non-votes” are counted as present for purposes of determining whether a quorum is present at the Annual Meeting. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

Under our bylaws, when a quorum is present at any meeting of stockholders, any proposal other than an election of directors is decided by a majority of the votes properly cast for and against such proposal, except where a larger vote is required by law or by our Amended and Restated Certificate of Incorporation, or certificate of incorporation, or bylaws.

To be elected, the directors nominated via Proposal No. 1 must receive a plurality of the votes properly cast on the election of directors, meaning that the director nominees receiving the most “For” votes will be elected. If nominees are unopposed, election requires only a single vote “For” or more. Votes withheld and broker “non-votes” will have no effect on the election of directors.

To ratify the appointment of our independent registered public accounting firm via Proposal No. 2, the affirmative vote of a majority of the votes properly cast for and against the proposal is required. Abstentions and broker “non-votes,” if any, will have no effect on the outcome of the vote.

If you are a stockholder of record, you can vote by proxy over the Internet or by telephone by following the instructions provided in the Notice, or, if you requested printed copies of the proxy materials by mail, you can vote by mailing, signing and dating your proxy card as described in the proxy materials. In order to be counted, proxies submitted by Internet or telephone must be received by the cutoff time of 11:59 p.m. Eastern Time on June 4, 2025. Proxies submitted by mail must be received by our Secretary before the start of the Annual Meeting.

If you are a beneficial owner of shares held in street name, please follow the instructions from your broker, bank or other nominee on how to vote.

If you are a shareholder of record and properly submitted your proxy, the persons named as proxies will vote the shares represented by your proxy in accordance with your instructions. If you submit such a proxy without giving voting instructions, your shares will be voted in the manner recommended by the board of directors on all matters presented in

this proxy statement. You may also authorize another person or persons to act for you as proxy in a writing, signed by you or your authorized representative, specifying the details of those proxies’ authority. The original writing must be given to each of the named proxies, although it may be sent to them by electronic transmission if, from that transmission, it can be determined that the transmission was authorized by you. If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in your proxy and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

If you are a beneficial owner of shares held in street name and you do not instruct your broker, bank or other nominee how to vote your shares, your broker, bank or other nominee may still be able to vote your shares in its discretion. In this regard, under the rules of the New York Stock Exchange, or 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. If your shares are held in “street name” by a brokerage firm, your brokerage firm is required to vote your shares according to your instructions. If you do not give instructions to your brokerage firm, the brokerage firm will still be able to vote your shares with respect to certain “routine” items but will not be allowed to vote your shares with respect to “non-routine” items. Proposal No. 1 is considered to be a “non-routine” item. If you do not instruct your broker how to vote with respect to this proposal, your broker may not vote for this proposal, and that vote will be counted as a broker “non-vote.” Proposal No. 2 is considered to be a “routine” item, and your brokerage firm will be able to vote on this proposal even if it does not receive instructions from you. 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 must provide voting instructions to your broker, bank or other nominee by the deadline provided in the materials you receive from your broker, bank or other nominee.

You may revoke your proxy by (1) following the instructions on the Notice and entering a new vote by mail that we receive before the start of the Annual Meeting or over the Internet or by telephone by the cutoff time of 11:59 p.m. Eastern Time on June 4, 2025, (2) attending and voting at the Annual Meeting (although attendance without voting at the Annual Meeting will not revoke a proxy), or (3) by filing an instrument in writing revoking the proxy or another duly executed proxy bearing a later date with our corporate secretary. Any written notice of revocation or subsequent proxy card must be received by our Secretary before the start of the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our Secretary or sent to our principal executive offices at Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attention: Secretary.

If a broker, bank, or other nominee holds your shares, you must contact such broker, bank, or other nominee in order to find out how to change your vote.

At least 10 days before the Annual Meeting, a list of the stockholders entitled to vote at the Annual Meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder will be open to the examination of any stockholder at the Company’s principal executive office.

We plan to announce preliminary voting results at the Annual Meeting and will publish final results, if available, in a Current Report on Form 8-K to be filed with the SEC within four business days following the Annual Meeting.

This Proxy Statement contains two proposals requiring stockholder action. Proposal No. 1 requests the election of three Class I directors to our board of directors. Proposal No. 2 requests the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025. Each of the proposals is discussed in more detail in the pages that follow.

Our board of directors currently consists of eight members. There are three directors in the class whose term of office expires at the Annual Meeting. In accordance with the terms of our certificate of incorporation and bylaws, our board of directors is divided into three classes, Class I, Class II and Class III, with members of each class serving staggered three-year terms. The members of the classes are divided as follows:

Upon the expiration of the term of a class of directors, directors in that class will be eligible to be elected for a new three-year term at the annual meeting of stockholders in the year in which their term expires.

Our certificate of incorporation and bylaws provide that the authorized number of directors may be changed only by resolution of our board of directors. Our certificate of incorporation also provides that our directors may be removed only (i) for cause and (ii) only by the affirmative vote of the holders of at least two-thirds (2/3) of the outstanding shares then entitled to vote in an election of directors, and that any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our remaining directors then in office.

Our board of directors has nominated Jitendra Mohan, Stefan Dyckerhoff and Bethany Mayer for election as the Class I directors at the Annual Meeting. The nominees are presently directors. Ms. Mayer, who joined the board of directors in 2024, was recommended by a non-management director. She was nominated by the nominating and corporate governance committee after an extensive and careful evaluation was conducted by the Chair of the nominating and corporate governance committee.

Each of the nominees has consented to being named as a nominee and, thus, indicated a willingness to continue to serve as directors, if elected. If the nominees become unable or unwilling to serve, however, the proxies may be voted for a substitute nominee selected by our board of directors. If elected, the Class I directors would serve for a three-year term ending at the annual meeting of stockholders to be held in 2028 or until his or her successor has been duly elected and qualified or until his or her earlier resignation, death or removal.

The following table identifies our Class I directors and sets forth their principal occupation and business experience during the last five years and their ages as of April 15, 2025.

Mr. Mohan holds a Bachelor of Technology degree in Electrical Engineering from Indian Institute of Technology, Bombay, and a Master of Science degree in Electrical Engineering from Stanford University.

To be elected, the directors nominated via Proposal No. 1 must receive a plurality of the votes properly cast on the election of directors, meaning that the director nominees receiving the most “For” votes will be elected. If nominees are unopposed, election requires only a single vote or more. Votes withheld and broker “non-votes” will have no effect on the election of directors.

Properly submitted proxies will be voted in favor of the above nominees unless a contrary specification is made in the proxy or at the Annual Meeting. The nominees have consented to serve as our directors, if elected. However, if the nominees are unable to serve or for good cause will not serve as a director, the proxies will be voted for the election of such substitute nominee as our board of directors may designate.

The proposal for the election of directors relates solely to the election of Class I directors nominated by our board of directors.

The board of directors unanimously recommends voting “FOR” the election of each of Jitendra Mohan, Stefan Dyckerhoff and Bethany Mayer as the Class I directors, to each serve for a three-year term ending at the annual meeting of stockholders to be held in 2028.

The following table and biographies identify our directors continuing in office and set forth their principal occupation and business experience during the last five years and their ages as of April 15, 2025.

The principal occupation and employment during the past five years of each of our directors and executive officers was carried on, in each case except as specifically identified above, with a corporation or organization that is not a parent, subsidiary or other affiliate of us. There is no arrangement or understanding between any of our directors and executive officers and any other person or persons pursuant to which he or she is to be selected as a director or executive officer, respectively.

There are no material legal proceedings to which any of our executive officers is a party adverse to us or our subsidiary or in which any such person has a material interest adverse to us or our subsidiary.

Astera Labs’ stockholders are being asked to ratify the appointment by the audit committee of the board of directors of PricewaterhouseCoopers LLP as Astera Labs’ independent registered public accounting firm for the fiscal year ending December 31, 2025. PricewaterhouseCoopers LLP has served as Astera Labs’ independent registered accounting firm since 2021.

The audit committee is solely responsible for selecting Astera Labs’ independent registered public accounting firm for the fiscal year ending December 31, 2025. Stockholder approval is not required to appoint PricewaterhouseCoopers LLP as Astera Labs’ independent registered public accounting firm. However, the board of directors believes that submitting the appointment of PricewaterhouseCoopers LLP to the stockholders for ratification is good corporate governance. If the stockholders do not ratify this appointment, the audit committee will reconsider whether to retain PricewaterhouseCoopers LLP. If the selection of PricewaterhouseCoopers LLP is ratified, the audit committee, at its discretion, may direct the appointment of a different independent registered public accounting firm at any time it decides that such a change would be in the best interest of Astera Labs and its stockholders.

A representative of PricewaterhouseCoopers LLP is expected to participate in the Annual Meeting and will have an opportunity to make a statement if he or she desires to do so and to respond to appropriate questions from our stockholders.

Astera Labs incurred the following fees from PricewaterhouseCoopers LLP for the audit of the consolidated financial statements and for other services provided during the years ended December 31, 2024 and December 31, 2023.

All fees described above were pre-approved by the audit committee.

We have adopted a policy under which our audit committee must pre-approve all audit and permissible non-audit services to be provided by our independent registered public accounting firm. Our audit committee may pre-approve our independent registered public accounting firm to perform a specific project, set of services, or transaction for our company or certain categories of services for our company. As part of its review, our audit committee also considers whether the categories of pre-approved services are consistent with the SEC’s rules on auditor independence. Our audit committee has pre-approved all services provided by our independent registered public accounting firm since the pre-approval policy was adopted prior to our IPO.

To ratify the appointment of PricewaterhouseCoopers as our independent registered public accounting firm via Proposal No. 2, the affirmative vote of a majority of the votes properly cast for and against this proposal is required. Shares that are voted “abstain” and broker “non-votes”, if any, will not affect the outcome of this proposal.

The board of directors unanimously recommends voting “FOR” Proposal No. 2 to ratify the appointment of PricewaterhouseCoopers LLP as Astera Labs’ independent registered public accounting firm for the fiscal year ending December 31, 2025.

Applicable Nasdaq Stock Market LLC, or Nasdaq, rules require a majority of a listed company’s board of directors to be comprised of independent directors. In addition, the Nasdaq rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that compensation committee members satisfy independence criteria set forth in Rule 10C-1 under the Exchange Act. Under applicable Nasdaq rules, a director will only qualify as an “independent director” if, in the opinion of the listed company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our board of directors has undertaken a review of the independence of each director. Based on information provided by each director concerning his or her background, employment, and affiliations, our board of directors has determined that each of Manuel Alba, Craig Barratt, Stefan Dyckerhoff, Michael Hurlston, Jack Lazar and Bethany Mayer does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the applicable rules and regulations of the SEC and the listing standards of Nasdaq. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with us and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Our board of directors has established an audit committee, a compensation committee, and a nominating and corporate governance committee, and may establish other committees from time to time. Each of the audit committee, compensation committee, and nominating and corporate governance committee operates under a charter and each committee reviews its respective charter at least annually. A current copy of the charter for each of the audit committee, compensation committee, and nominating and corporate governance committee is posted on the corporate governance section of our website, https://ir.asteralabs.com/corporate-governance/governance-overview.

Jack Lazar, Bethany Mayer and Craig Barratt serve on the audit committee, which is chaired by Mr. Lazar. Our board of directors has determined that each member of the audit committee is “independent” for audit committee purposes as that term is defined in the rules of the SEC and the applicable Nasdaq rules, and each has sufficient knowledge in financial and auditing matters to serve on the audit committee. Our board of directors has designated each of Mr. Lazar and Ms. Mayer as an “audit committee financial expert,” as defined under the applicable rules of the SEC. During the fiscal year ended December 31, 2024, the audit committee met five times. The report of the audit committee is included in this proxy statement under “Report of the Audit Committee.” The audit committee’s responsibilities include:

All audit and non-audit services, other than de minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee.

Michael Hurlston and Stefan Dyckerhoff serve on the compensation committee, which is chaired by Mr. Hurlston. Our board of directors has determined that each member of the compensation committee is “independent” as defined in the applicable Nasdaq and SEC rules. During the fiscal year ended December 31, 2024, the compensation committee met six times. The compensation committee’s responsibilities include:

The compensation committee has the authority under its charter to retain outside consultants or advisors, as it deems necessary or advisable. In accordance with this authority, the compensation committee has engaged the services of Compensia, Inc., or Compensia, as an outside compensation consultant.

As requested by the compensation committee, in 2024, Compensia’s services to the compensation committee included assisting us in developing our peer group composition, analyzing benchmarking data with respect to our executives’ overall individual compensation and board of directors’ compensation for board and committee service, and providing information regarding current trends and developments in executive compensation, industry employee compensation retention practices, equity-based awards and employee stock purchase programs based on our peer group.

All executive compensation services provided by Compensia during 2024 were conducted under the direction or authority of the compensation committee, and all such work performed by Compensia was approved by the compensation committee. Neither Compensia nor any of its affiliates maintains any other direct or indirect business relationships with us or any of our subsidiaries. The compensation committee evaluated whether any work provided by Compensia raised any conflict of interest for services performed during 2024 and determined that it did not.

As noted above, the Company’s compensation committee consists of Michael Hurlston and Stefan Dyckerhoff, each of whom served on the Company’s compensation committee in 2024. None of the members of the compensation committee in 2024 is currently or has been at any time one of our officers or employees. No executive officer currently serves, or has served during the last year, as a member of the board of directors or compensation committee of any entity that has one or more members of our board of directors serving as executive officers.

Stefan Dyckerhoff and Jack Lazar serve on the nominating and corporate governance committee, which is chaired by Mr. Dyckerhoff. Our board of directors has determined that each member of the nominating and corporate governance committee is “independent” as defined in the applicable Nasdaq rules. During the fiscal year ended December 31, 2024 and following its formation in March 2024, the nominating and corporate governance committee met three times. The nominating and corporate governance committee’s responsibilities include:

Our nominating and corporate governance committee is responsible for identifying individuals qualified to serve as directors, consistent with criteria approved by our board of directors, and recommending such persons to be nominated for election as directors, except where we are legally required by contract, law or otherwise to provide third parties with the right to nominate.

Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with management. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees, including being able to read and understand basic financial statements and having personal integrity and ethics. The nominating and corporate governance committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks or any other means that the nominating and corporate governance committee deems to be appropriate in the evaluation process. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval to fill a vacancy or as director nominees for election to the board of directors by our stockholders each year in the class of directors whose term expires at the relevant annual meeting.

The qualifications, qualities and skills that our nominating and corporate governance committee believes must be met by a committee-recommended nominee for a position on our board of directors are as follows:

Our priority in the selection of board members is identification of members who will further the interests of our stockholders through their established record of professional accomplishment, their ability to contribute positively to the collaborative culture among board members and their knowledge of our business and understanding of the competitive landscape. We do not have a specific board of directors diversity policy, but we fully appreciate the value

of having a range of backgrounds, experiences, skill sets and perspectives on the Board. The Board believes that having a variety of points of view improves the quality of dialogue, contributes to a more effective decision-making process and enhances overall culture in the boardroom and is important to serving the long-term interests of stockholders.

Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates. Any such recommendations should be submitted to our Secretary at our principal executive offices by December 25, 2025 and should include appropriate biographical and background material to allow the nominating and corporate governance committee to properly evaluate the potential director candidate and the number of shares of our stock beneficially owned by the stockholder recommending the candidate as well as the name and address of the recommending stockholder. Stockholder director recommendations should be addressed to Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attention: Secretary. Assuming that biographical and background material has been provided on a timely basis, any recommendations received from stockholders will be evaluated in the same manner as potential nominees proposed by the nominating and corporate governance committee. If our board of directors determines to nominate a stockholder-recommended candidate and recommends his or her election, then his or her name will be included on our proxy card for the next annual meeting of stockholders. See “Stockholder Proposals” for a discussion of submitting stockholder proposals.

The full board of directors met five times during 2024. During 2024, each member of the board of directors attended at least 75% or more of the aggregate of the total number of meetings of the board of directors (held during the period for which such person has been a director) and the total number of meetings held by all committees of the board of directors on which such person served (during the periods that such person served).

Each member of the board of directors is expected to make reasonable efforts to attend the Annual Meeting.

We have adopted an insider trading policy governing the purchase, sale and/or other disposition of our securities by employees, consultants, directors, and officers, which we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations and the applicable exchange listing standards. In addition, with regard to the company’s trading in its own securities, it is the company’s policy to comply with the federal securities laws and the applicable exchange listing requirements.

Our board of directors has adopted an additional policy that governs adoption, modification and termination of written securities trading plans, known as Rule 10b5-1 plans, by our directors, executive officers and certain other persons, or Covered Persons. These plans are intended to take advantage of a safe harbor provided under SEC rules from liability for violating federal antifraud prohibitions that proscribe certain insider trading, including Section 10(b) of the Exchange Act.

Our board of directors has adopted an insider trading policy that applies to all of our employees, consultants, directors, and officers. This policy prohibits the following transactions in our company securities: short sales, the purchase or sale of derivative securities or hedging transactions, the use of our company securities as collateral subject to margin calls, and the pledge of our company securities as collateral for loans. Any waiver of our insider trading policy by our Compliance Officer must be reported to the audit committee.

We have adopted a written code of business conduct and ethics that applies to all of our directors, officers and employees, including Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. A current copy of the code is posted on the corporate governance section of our website, which is located at https://ir.asteralabs.com/corporate-governance/governance-overview. If we make any substantive amendments to, or grant any waivers from, the code of business conduct and ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a current report on Form 8-K.

Prior to our IPO, our board of directors adopted a compensation recovery policy as required by Rule 10D-1 under the Exchange Act and the corresponding Nasdaq listing standards. The compensation recovery policy generally provides, subject to certain exceptions, that if we are required to prepare a restatement of our financial statements, we will recover from our executive officers any incentive-based compensation that was erroneously awarded in excess of the amount that otherwise would have been awarded based on restated amounts in the restated financial statements. The recovery period is the three completed fiscal years immediately preceding the date that our board of directors concludes that we are required to restate our financial statements. Incentive-based compensation includes any compensation that is granted, earned, or vested based on the attainment of a financial reporting measure of the Company.

In addition, as a public company subject to Section 304 of the Sarbanes-Oxley Act of 2002, if we are required to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws as a result of misconduct, our Chief Executive Officer and Chief Financial Officer may be legally required to reimburse us for any bonus or other incentive-based or equity-based compensation they receive.

Manuel Alba has served as Chair of the board of directors since 2018. Manuel is an independent, non-management director. The Chair is primarily responsible for overseeing the operations and affairs of the board of directors and acting as a liaison between management and the board of directors. Our non-employee, independent directors meet at regularly scheduled executive sessions without management participation. Manuel Alba, as Chair of the board of directors, presides at those sessions.

Currently, the role of Chair is separated from the role of Chief Executive Officer. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing the Chair to lead the board of directors in its fundamental role of providing advice to, and independent oversight of, management. Our board of directors recognizes the time, effort, and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our Chair, particularly as the board of directors’ oversight responsibilities continue to grow. While our bylaws and our Corporate Governance Guidelines do not require that our Chair and Chief Executive Officer positions be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time and reflects our commitment to strong corporate governance. If the Chair and Chief Executive Officer were to be the same person, the board of directors may consider appointment of a Lead Independent Director.

Our board of directors has responsibility for the oversight of our risk management processes and, either as a whole or through its committees, regularly discusses with management our major risk exposures, their potential impact on our business, and the steps we take to manage them. The risk oversight process includes receiving regular reports from board committees and members of senior management to enable our board of directors to understand our risk identification, risk management, and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, cybersecurity, strategic, and reputational risk.

Our board of directors provides to every stockholder the ability to communicate with our board of directors, as a whole, and with individual directors on our board of directors through an established process for stockholder communication. For a Securityholder Communication directed to the board of directors as a whole, securityholders

may send such communication to the attention of the Chair of our board of directors via U.S. Mail or Expedited Delivery Service to Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attn: Chair of the Board of Directors, or by email to [email protected].

For a Securityholder Communication directed to an individual director in his or her capacity as a member of the board of directors, securityholders may send such communication to the attention of the individual director via U.S. Mail or Expedited Delivery Service to Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attn: [Name of Individual Director], or by email to [email protected].

We will forward by U.S. Mail any such stockholder communication to each director to whom such communication is addressed and to the Chair of our board of directors in his or her capacity as a representative of our board of directors, at the address specified by each such director and the Chair of our board of directors.

The following table presents the total compensation for each person who served as a non-employee director of our board of directors during the fiscal year ended December 31, 2024, or FY 2024. Other than as set forth in the table and described more fully below, we did not pay any compensation, make any equity awards or non-equity awards to, or pay any other compensation to any of the non-employee members of our board of directors in FY 2024 for their services as members of the board of directors. During FY 2024, Messrs. Mohan and Gajendra served as members of our board of directors, as well as serving as employees, and were not separately compensated for their services as members of the board of directors. The compensation paid to Messrs. Mohan and Gajendra are reported in the “Executive Compensation—2024 Summary Compensation Table” below.

We maintain a Non-Employee Director Compensation Policy pursuant to which our non-employee directors are eligible to receive the following cash retainers and equity awards (which will be prorated for partial years of service):

In addition, the non-employee director compensation policy provides that, upon initial election to our board of directors, each non-employee director will be granted a restricted stock unit award with a fair market value of $330,000, or Initial Grant. The Initial Grant will vest in equal installments on the first, second, and third anniversaries of the grant date, subject to continued service with the Company through the applicable vesting date. Furthermore, on the date of each annual meeting of stockholders following the completion of this offering, each non-employee

director who continues as a non-employee director following such meeting will be granted an annual restricted stock unit award with a fair market value of $200,000, or Annual Grant. The Annual Grant will vest in full on the earlier of (i) the first anniversary of the grant date or (ii) our next annual meeting of stockholders, subject to continued service with the Company through the applicable vesting date. Such awards are subject to full accelerated vesting upon a change in control of the Company.

The aggregate amount of compensation, including both equity compensation and cash compensation, paid to any non-employee director in a calendar year period will not exceed $1,000,000 in the first calendar year such individual becomes a non-employee director and $750,000 in any other calendar year.

We will reimburse all reasonable out-of-pocket expenses incurred by directors for their attendance at meetings of the board of directors or any committee thereof.

Employee directors will receive no additional compensation for their service as a director.

Our executive compensation programs are designed to attract, motivate, incentivize and retain our executive officers, who contribute to our long-term success. Pay that is competitive, rewards performance and effectively aligns the interests of our executive officers with those of our long-term stockholders is key to our compensation program design and decisions. We structure our executive compensation programs to be weighted towards long-term equity incentives that correlate with the growth of sustainable long-term value for our stockholders.

We are an “emerging growth company” under applicable federal securities laws and therefore permitted to conform with certain reduced public company reporting requirements. We provide in this proxy statement the scaled disclosure permitted under the Jumpstart Our Business Startups Act of 2012 (the JOBS Act). In addition, as an emerging growth company, we are not required to conduct votes seeking approval, on an advisory, non-binding basis, of the compensation of our named executive officers or the frequency with which such votes must be conducted.

The compensation provided to our named executive officers for FY 2024 is detailed in the 2024 Summary Compensation Table and accompanying footnotes and narrative that follow. Our named executive officers for FY 2024 were:

To date, the compensation of our named executive officers has consisted of a combination of base salary, long-term incentive compensation, and non-equity plan compensation, as more fully described below. Our named executive officers, like all full-time employees, are eligible to participate in our health and welfare benefit plans.

The following table sets forth information regarding compensation awarded to, earned by, or paid to each of our named executive officers for services rendered to us in all capacities during FY 2024 and the fiscal year ended December 31, 2023, or FY 2023, as applicable.

Each of the named executive officers is paid a base salary commensurate with his skill set, experience, performance, role, and responsibilities. As of the beginning of FY 2024, the annual base salary for each of Messrs. Mohan, Gajendra, and Tate was $ 310,000. We increased the annual base salary for each of Messrs. Mohan, Gajendra, and Tate to $600,000, $600,000, and $450,000, effective February 1, 2024.

We believe long-term equity incentive awards encourage retention, provide our executives with a strong link to our long-term performance, create an ownership culture, and help to align the interests of our executives and our stockholders. Accordingly, our board of directors and compensation committee periodically review the equity incentive compensation of our named executive officers and may grant equity incentive awards to them from time to time. During FY 2024, we granted Messrs. Gajendra, Mohan, and Tate 2,704,335, 2,704,335, and 162,476 restricted stock units, respectively, which generally vest over a period of four years, or, in the case of a portion of Mr. Tate’s grant, at the end of one year, subject to their respective continued service with us on each applicable vesting date, subject to Messrs. Gajendra’s, Mohan’s and Tate’s continued service with us on each applicable vesting date. For additional description of the awards granted to our named executive officers, please see “Outstanding Equity Awards at 2024 Fiscal Year-End” below.

Our named executive officers, as well as other executive officers, are eligible to participate in our Senior Executive Cash Incentive Bonus Plan, or the Bonus Plan, which is an annual bonus program and is intended to reward our named executive officers for meeting objective or subjective performance goals for a fiscal year. The Bonus Plan provides for cash payments based upon the attainment of performance targets established by the compensation committee, which may relate to financial and operational measures or objectives with respect to the Company, as well as individual performance objectives. Each executive officer who is selected to participate in the Bonus Plan will have a target bonus opportunity set for each performance period.

With respect to performance in FY 2024, the target bonus opportunity as a percentage of base salary (in place as of February 1, 2024) for each of Messrs. Mohan, Gajendra, and Tate was 115%, 115% and 75 %, respectively.

Based on the Company’s achievement of certain performance goals and metrics related to our 2024 corporate objectives, the compensation committee determined that the bonuses would be paid in the amounts as set forth above in the Summary Compensation Table.

We have entered into offer letters with Messrs. Mohan and Gajendra and an employment agreement with Mr. Tate the material terms of which are summarized below. All our named executive officers are subject to our standard confidential information and invention assignment agreement. The numbers below with respect to equity awards were adjusted to reflect the Company’s five-to-one forward stock split in August 2021 and subsequent February 2024 two-for-one reverse stock split.

We entered into an offer letter with Mr. Mohan, dated March 13, 2018. Mr. Mohan’s offer letter provides for at-will employment, an initial annual base salary of $160,000, a restricted stock grant for 9,500,000 shares of our common stock, and eligibility to participate in any benefit plans generally made available to employees.

We entered into an offer letter with Mr. Gajendra, dated March 13, 2018. Mr. Gajendra’s offer letter provides for at-will employment, an initial annual base salary of $160,000, a restricted stock grant for 9,250,000 shares of our common stock, and eligibility to participate in any benefit plans generally made available to employees.

We entered into an employment agreement with Mr. Tate, dated July 21, 2020, providing for at-will employment. Mr. Tate’s employment agreement provides him with (i) an annual base salary of $49,920, (ii) an option to purchase

975,000 shares of our common stock, (iii) eligibility to participate in any benefit plans generally made available to employees, and (iv) reimbursement of reasonable business expenses. In addition, Mr. Tate is subject to our standard confidentiality and non-solicitation covenants.

In August 2023, our board of directors adopted the Change of Control Severance Policy for Principal Executive Officers, or the Severance Policy, pursuant to which certain executive officers are eligible for severance upon either a (A) termination by us for any reason other than for “good cause” (as such term is defined in the Severance Policy) or (B) resignation by an eligible executive for “good reason” (as such term is defined in the Severance Policy), in each case, during the period three months prior to or 12 months following a “change of control” (as defined in the Severance Policy), or a Qualifying Termination.

Upon a Qualifying Termination, eligible executives are entitled to (i) a lump-sum payment equal to six (6) months of the executive’s base salary in effect on the termination date, (ii) a lump-sum payment equal to 50% of the executive’s annual target bonus, (iii) a lump-sum payment equal to the executive’s target bonus, pro-rated for the number of months employed during the fiscal year prior to the termination date, (iv) up to six (6) months of company-paid COBRA payments equal to the premiums we would have made to provide health insurance to the executive if the executive had remained employed by us, and (v) with respect to equity incentives, (A) 50% accelerated vesting of all then unvested equity awards as of the executive’s date of termination, if executive has been continuously employed by us for fewer than twenty-four (24) months on the date of termination, or (B) full accelerated vesting of all unvested equity awards as of the executive’s date of termination, if executive has been continuously employed by us for twenty-four (24) months or greater on the date of termination, subject, in each case, to the executive’s timely execution of a separation agreement including a release in favor of us.

Additionally, to the extent the parties to the change of control do not provide for the assumption, continuation or substitution of our equity awards, subject to the executive’s continued employment with us through immediately prior to the effective date of such change of control, all equity awards with time-based vesting conditions that are not vested and/or exercisable immediately prior to the effective time of the change of control shall become fully vested and exercisable as of the effective time of the change of control.

The payments and benefits provided under the Severance Policy in connection with a change in control may not be eligible for a federal income tax deduction by us pursuant to Section 280G of the U.S. Internal Revenue Code of 1986, as amended, or the Code. These payments and benefits may also subject an eligible executive to an excise tax under Section 4999 of the Code. If the payments or benefits payable in connection with a change in control would be subject to the excise tax imposed under Section 4999 of the Code, then those payments or benefits will be reduced if such reduction would result in a higher net after-tax benefit to the eligible executive.

We participate in a retirement savings plan, or 401(k) plan, which is intended to qualify for favorable tax treatment under Section 401(a) of the Code, and contains a cash or deferred feature that is intended to meet the requirements of Section 401(k) of the Code. U.S. employees who are at least 18 years of age are generally eligible to participate in the 401(k) plan, subject to certain criteria. Participants may make pre-tax and certain after-tax (Roth) salary deferral contributions to the plan from their eligible earnings up to the statutorily prescribed annual limit under the Code. Participants who are 50 years of age or older may contribute additional amounts based on the statutory limits for catch-up contributions. Participant contributions are held in trust as required by law. An employee’s interest in his or her salary deferral contributions is 100% vested when contributed.

We believe our compensation structure for all employees does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.

The following table sets forth information concerning outstanding equity awards held by our named executive officers as of December 31, 2024.

The following table provides information as of December 31, 2024 with respect to the shares of our common stock that may be issued under our existing equity compensation plans.

Our audit committee charter provides that the audit committee has the primary responsibility for reviewing and approving or disapproving “related party transactions,” which are transactions, arrangements or relationships (or any series of similar transactions, arrangements or relationships) between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. For purposes of this policy, a related person will be defined as a director, executive officer, nominee for director or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members. In determining whether to approve or ratify any such transaction, our audit committee will take into account, among other factors it deems appropriate, (i) whether the transaction is on terms no less favorable than terms generally available to unaffiliated third parties under the same or similar circumstances and (ii) the extent of the related party’s interest in the transaction.

All of the transactions described below were entered into prior to the adoption of this policy. Accordingly, each was approved by disinterested members of our board of directors after making a determination that the transaction was executed on terms no less favorable than those that could have been obtained from an unrelated third party.

In addition to the compensation arrangements, including employment, termination of employment and change in control arrangements, and indemnification arrangements discussed, when required, in the section titled “Executive Compensation” and the registration rights described below, the following is a description of each transaction since January 1, 2024 and each currently proposed transaction in which:

We are party to an amended and restated investors’ rights agreement, dated as of May 17, 2022, that provides, among other things, certain holders of our capital stock, including entities affiliated with Sutter Hill Ventures and Fidelity Management and Research, the Mohan Trust, the Gajendra Trust, the Tate Trust, and Alba 2003 Living Trust, Casa Alameda 2007, LLC, and MAR 2011 Children’s Trust, which are trusts affiliated with our Director, Manuel Alba, or, collectively, the Alba Trust, with registration rights.

We have granted stock options to purchase common stock and RSUs to our executive officers and certain of our directors. See the section titled “Executive Compensation” for a description of our FY 2024 equity awards. In addition, in 2024, we granted a total of 2,704,335, 2,704,335, 162,476 and 62,804 RSUs to our Chief Executive Officer, President, Chief Financial Officer, and General Counsel, respectively, for the purpose of retaining their services in their roles in our Company.

Our certificate of incorporation contains provisions that limit the liability of our directors and officers for monetary damages to the fullest extent permitted by Delaware law. Consequently, our directors and officers will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors and officers, except liability for the following:

Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment or repeal. If the DGCL is amended to provide for further limitations on the personal liability of directors and officers of corporations, then the personal liability of our directors and officers will be further limited to the greatest extent permitted by the DGCL.

In addition, our bylaws provide that we will indemnify, to the fullest extent permitted by law, any person who is or was a party or is threatened to be made a party to any action, suit or proceeding by reason of the fact that he or she is or was one of our directors or officers or is or was serving at our request as a director or officer of another corporation, partnership, joint venture, trust, or other enterprise. Our bylaws further provide that we may indemnify to the fullest extent permitted by law any person who is or was a party or is threatened to be made a party to any action, suit, or proceeding by reason of the fact that he or she is or was one of our employees or agents or is or was

serving at our request as an employee or agent of another corporation, partnership, joint venture, trust or other enterprise. Our bylaws also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final disposition of any action or proceeding, subject to very limited exceptions.

Further, we have entered into indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the DGCL. These indemnification agreements require us, among other things, to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require us to advance all expenses incurred by the directors and executive officers in investigating or defending any such action, suit, or proceeding. We believe that these agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.

The limitation of liability and indemnification provisions that are included in our certificate of incorporation, our bylaws and in indemnification agreements that we have entered into (or may enter into in the future) with our directors and executive officers may discourage stockholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against our directors and executive officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be harmed to the extent that we pay the costs of settlement and damage awards against directors and executive officers as required by these indemnification provisions. At present, we are not aware of any pending litigation or proceeding involving any person who is or was one of our directors, officers, employees or other nominees or is or was serving at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, for which indemnification is sought, and we are not aware of any threatened litigation that may result in claims for indemnification.

We have obtained insurance policies under which, subject to the limitations of the policies, coverage is provided to our directors and executive officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or executive officer, including claims relating to public securities matters, and to us with respect to payments that may be made by us to these directors and executive officers pursuant to our indemnification obligations or otherwise as a matter of law.

Certain of our non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities incurred in their capacity as members of our board of directors.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or persons controlling our company pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

The following table sets forth information, to the extent known by us or ascertainable from public filings, with respect to the beneficial ownership of our common stock as of March 1, 2025 by:

The column entitled “Shares Beneficially Owned” is based on a total of 164,720,004 shares of our common stock outstanding as of March 1, 2025.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Shares of our common stock subject to options or RSUs that are currently exercisable or exercisable within 60 days of March 1, 2025 are considered outstanding and beneficially owned by the person holding the options for the purpose of calculating the percentage ownership of that person but not for the purpose of calculating the percentage ownership of any other person. Except as otherwise noted, the persons and entities in this table have sole voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to community property laws, where applicable. Except as otherwise indicated in the table below, addresses of named beneficial owners are in care of Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054.

Section 16(a) of the Exchange Act requires the Company’s directors and executive officers, and persons who own more than ten percent of a registered class of the Company’s equity securities, to file with the SEC initial reports of ownership and reports of changes in ownership of common stock and other equity securities of the Company. Officers, directors and greater than ten percent shareholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file.

To the Company’s knowledge, based solely on a review of the copies of such reports filed on the SEC’s EDGAR system and written representations that no other reports were required, during the fiscal year ended December 31, 2024, all Section 16(a) filing requirements applicable to its officers, directors and greater than ten percent beneficial owners were complied with.

The audit committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2024 with our management. The audit committee has also reviewed and discussed with PricewaterhouseCoopers LLP, our independent registered public accounting firm, the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the Public Company Accounting Oversight Board, or the PCAOB. The audit committee has also received the written disclosures and the letter from PricewaterhouseCoopers LLP required by the applicable requirements of the PCAOB regarding the independent accountants’ communications with the audit committee concerning independence and has discussed with PricewaterhouseCoopers LLP its independence. Based on the foregoing, the audit committee has recommended to our board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and be filed with the SEC.

The information contained in this report shall not be deemed to be (1) “soliciting material,” (2) “filed” with the SEC, (3) subject to Regulations 14A or 14C of the Exchange Act, or (4) subject to the liabilities of Section 18 of the Exchange Act. This report shall not be deemed incorporated by reference into any of our other filings under the Exchange Act or the Securities Act, except to the extent that we specifically incorporate it by reference into such filing.

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” notices of internet availability of proxy materials or other annual meeting materials with respect to two or more stockholders sharing the same address. This means that only one copy of our notice of internet availability of proxy materials or other meeting materials may have been sent to multiple stockholders in your household 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 you want to receive separate copies of the notice of internet availability of proxy materials or other annual meeting materials in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us. You may contact us and we will promptly deliver a separate copy of any such document to you upon written or oral request to Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attention: Secretary, telephone: (408) 766-3806.

A stockholder who would like to have a proposal presented at the 2026 annual meeting of stockholders, pursuant to Rule 14a-8 of the Exchange Act, must be received by us no later than December 25, 2025 in order to be included in the proxy statement relating to that meeting. However, if the date of the 2026 annual meeting of stockholders is changed by more than 30 days from the date of the previous year’s meeting, then the deadline is a reasonable time before we begin to print and send our proxy statement for the 2026 annual meeting of stockholders. SEC rules set standards for eligibility and specify the types of stockholder proposals that may be excluded from a proxy statement. Rule 14a-8 proposals must be delivered by mail to our principal executive offices. Stockholder proposals should be addressed to Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attention: Secretary. We also encourage you to submit any such proposals via email to [email protected]. To comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934 no later than April 6, 2026.

In addition, our bylaws require that we be given advance notice of nominations of persons for election to the Board of Directors and the proposal of other business to be considered by stockholders for action at an annual meeting of stockholders (other than matters included in our proxy statement in accordance with Rule 14a-8 under the Exchange Act). For nominations or other business to be properly brought before an annual meeting in accordance with our bylaws, the stockholder must have given timely notice in writing to the Secretary of the Company and have provided the other information and satisfied the other requirements described in our bylaws. To be timely, the required notice must be in writing and received by our corporate secretary at our principal executive offices not later than the close of business on the 90th day nor earlier than the close of business on the 120th day prior to the first anniversary of the preceding year’s annual meeting. However, in the event that the date of the annual meeting is first convened more than 30 days before, or delayed by more than 60 days from the first anniversary of the preceding year’s annual meeting, a stockholder’s notice must be so received by the corporate secretary not later than the close of business on the later of (A) the 90th day prior to such annual meeting or (B) the tenth day following the day on which public announcement of the date of such meeting is first made. For stockholder proposals to be brought before the 2026 annual meeting of stockholders, the required notice must be received by our Secretary at our principal executive offices no earlier than February 5, 2026 and no later than March 7, 2026. Stockholder proposals and the required notice should be addressed to Astera Labs, Inc., 2901 Tasman Drive, Suite 205, Santa Clara, CA 95054, Attention: Secretary.

Our board of directors does not know of any other matters to be brought before the Annual Meeting. If any other matters not mentioned in this proxy statement are properly brought before the meeting, the individuals named in the enclosed proxy intend to use their discretionary voting authority under the proxy to vote the proxy in accordance with their best judgment on those matters.
