April 15 2025,

To our shareholders,

2024 was a transformative year for GRAIL as we separated from Illumina and began publicly trading in June. Since the separation from Illumina, we have made great progress as a public company. We’ve seen strong growth for Galleri in a largely pre-reimbursement environment, progressed our regulatory efforts, improved our cost efficiency, and recently rolled out a new version of the test, preparing us for scalability.

We sold more than 137,000 tests in 2024, and achieved a 45% increase in U.S. Galleri revenue as compared with 2023. Galleri works by detecting DNA fragments shed into the bloodstream by tumor cells and localizing that signal to a specific organ or tissue type. The Galleri test is identifying deadly cancers in asymptomatic adults in clinical care today.

As an early leader in the field, we continue to establish strong relationships within the cancer and primary care communities, including collaborations with academic and community medical centers, opinion leaders, policy and advocacy groups. We are building on our clinical evidence program, as we look towards a future where we can detect more cancers through screening, before symptoms arise. We continue to make progress towards FDA product approval and reimbursement. In 2024, we completed final study visits for our two registrational studies, the NHS-Galleri study and PATHFINDER 2, and continue to anticipate completion of our PMA filing in the first half of 2026.

In the second half of 2024, we implemented a significant restructure intended to extend our capital runway into 2028, enabling us sufficient capital to achieve some major anticipated milestones, including the completion of our modular PMA submission for FDA approval of Galleri. Additionally, in late 2024, we began transitioning to an updated Galleri test leveraging an automated and integrated workflow in the laboratory. We believe this more efficient workflow will enable long-term cost reductions and support growth at population scale.

At GRAIL, we are looking to a future where we can detect more cancers through screening, before symptoms arise, which we believe will enable more effective treatments and reduce costs of care. We believe we are in a strong financial position, and are pleased with the momentum we are seeing as we continue to drive multi-cancer early detection from an idea towards becoming a new standard of care alongside existing cancer screenings.

On behalf of GRAIL’s Board of Directors, leadership team and employees, we thank you for your continued support of our efforts to advance our mission to detect cancer early, when it can be cured. Your vote is important, and we hope that you will join us virtually at our 2024 Annual Meeting of Stockholders on May 29, 2025.

Sincerely,

Bob Ragusa

Chief Executive Officer

PROXY STATEMENT FOR THE 2025 ANNUAL MEETING OF STOCKHOLDERS

April 15, 2025

This proxy statement is furnished in connection with the solicitation by the Board of Directors of GRAIL, Inc. (the “Board of Directors” or “Board”) of proxies to be voted at our Annual Meeting of Stockholders to be held on Thursday, May 29, 2025 (the “Annual Meeting”), at 4:00 p.m. Eastern Time, via live webcast, and at any continuation, postponement, or adjournment of the Annual Meeting.

Holders of our common stock as of the close of business on March 31, 2025 (the “Record Date”), may vote at the Annual Meeting. As of the Record Date, there were 35,296,858 shares of our common stock outstanding. Our common stock will vote as a single class on all matters described in this proxy statement for which your vote is being solicited. Stockholders are not permitted to cumulate votes with respect to the election of directors. Each share of stock is entitled to one vote on each proposal.

On June 24, 2024, (the “Distribution Date”), Illumina, Inc. (“Illumina”) completed a spin-off of GRAIL, Inc. (the “Spin-Off”). The Spin-Off was completed through a distribution of 85.5% of the Company’s outstanding common stock to the holders of record of Illumina’s common stock as of the close of business on June 13, 2024 (the “Distribution”), which resulted in the distribution of 31.0 million shares of common stock. As a result of the Distribution, the Company became an independent public entity. As of the record date, Illumina beneficially owns 12.76% of our common stock. See Security Ownership of Certain Beneficial Owners and Management. Illumina has agreed to vote any shares of our common stock that it retains in proportion to the votes cast by our other stockholders and to grant us a proxy to vote its shares of our common stock in such proportion.

This proxy statement and the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (the “2024 Form 10-K”) will be released on or about April 15, 2025 to our stockholders on the Record Date.

In this proxy statement, “we,” “us,” “our,” the “Company” and “GRAIL” refer to GRAIL, Inc.

INFORMATION ABOUT THIS PROXY STATEMENT

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

Notice of Internet Availability of Proxy Materials. As permitted by SEC rules, GRAIL is making this proxy statement and its 2024 Form 10-K available to its stockholders electronically via the Internet. On or about April 15, 2025, we mailed to our stockholders a Notice of Internet Availability of Proxy Materials (the “Internet Notice”) containing instructions on how to access this proxy statement and our 2024 Form 10-K and vote online. If you received an Internet Notice by mail, you will not receive a printed copy of the proxy materials in the mail unless you specifically request them. Instead, the Internet Notice instructs you on how to access and review all of the important information contained in the proxy statement and 2024 Form 10-K. The Internet Notice also instructs you on how you may submit your proxy over the Internet. If you received an Internet Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Internet Notice.

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

Householding. The SEC’s rules permit us to deliver a single set of proxy materials to one address shared by two or more of our stockholders. This delivery method is referred to as “householding” and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one set of proxy materials to multiple stockholders who share an address, unless we received contrary instructions from the impacted stockholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials, as requested, to any stockholder at the shared address to which a single copy of those documents was delivered. If you prefer to receive separate copies of the proxy materials, contact Broadridge Financial Solutions, Inc.

QUESTIONS AND ANSWERS ABOUT THE 2025 ANNUAL MEETING OF STOCKHOLDERS

WHO IS ENTITLED TO VOTE AT THE ANNUAL MEETING?

The Record Date for the Annual Meeting is March 31, 2025. You are entitled to vote at the Annual Meeting only if you were a stockholder of record at the close of business on that date, or if you hold a valid proxy for the Annual Meeting. Each share of common stock is entitled to one vote on each proposal. At the close of business on the Record Date, there were 35,296,858 shares of common stock issued and outstanding and entitled to vote at the Annual Meeting. Illumina has agreed to vote any shares of our common stock that it retains in proportion to the votes cast by our other stockholders and to grant us a proxy to vote its shares of our common stock in such proportion.

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

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

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

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

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

A quorum must be present at the Annual Meeting for any business to be conducted. The presence at the Annual Meeting, via live webcast or by proxy, of the holders of a majority in voting power of all common stock issued and outstanding and entitled to vote on the Record Date will constitute a quorum.

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

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

WHO CAN ATTEND AND VOTE AT THE ANNUAL MEETING?

In order to allow greater participation, the Annual Meeting will be held entirely online. You will be able to attend the Annual Meeting online and submit your questions by visiting www.virtualshareholdermeeting.com/GRAL2025. You will also be able to vote your shares electronically at the Annual Meeting.

To participate and vote at the Annual Meeting, you will need the 16-digit control number included in your Internet Notice, on your proxy card or on the instructions that accompanied your proxy materials. The meeting webcast will begin promptly at 4:00 p.m., Eastern Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 3:45 p.m., Eastern Time, and you should allow ample time for the check-in procedures. If your shares are held in street name and you did not receive a 16-digit control number, you may gain access to and vote at the Annual Meeting by logging in to your bank or brokerage firm’s website and selecting the stockholder communications mailbox to access the meeting. The control number will automatically populate. Instructions should also be provided on the voting instruction card provided by your bank or brokerage firm. If you lose your 16-digit control number, you may join the Annual Meeting as a “Guest,” but you will not be able to vote, ask questions, or access the list of stockholders as of the Record Date.

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

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the Virtual Stockholder Meeting log-in page.

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

As part of the Annual Meeting, we will hold a live Q&A session, during which we intend to answer questions submitted online during the meeting that are pertinent to the Company and the meeting matters, as time permits. Only stockholders that have accessed the Annual Meeting as a stockholder (rather than as a “Guest”) by following the procedures outlined above in “Who can attend the Annual Meeting?” will be permitted to submit questions during the Annual Meeting. Each stockholder is limited to no more than two questions. Questions should be succinct and only cover a single topic. We will not address questions that are, among other things:

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

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

•related to any pending, threatened or ongoing litigation;

•related to personal grievances;

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

•substantially repetitious of questions already made by another stockholder;

•in excess of the two question limit;

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

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

Additional information regarding the Q&A session will be available in the “Rules of Conduct” available on the Annual Meeting webpage for stockholders that have accessed the Annual Meeting as a stockholder (rather than as a “Guest”) by following the procedures outlined above in “Who can attend the Annual Meeting?”.

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

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

HOW DO I VOTE?

Stockholders of Record

We recommend that stockholders vote by proxy even if they plan to participate in the online Annual Meeting and vote electronically. If you are a stockholder of record, there are three ways to vote by proxy:

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

•by Telephone - You can vote by telephone by calling 1-800-690-6903 and following the instructions on the proxy card; or

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

Internet and telephone voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m., Eastern Time, on May 28, 2025. We encourage stockholders to submit their proxy via the Internet or telephone. Stockholders of record may vote during the Annual Meeting by visiting www.virtualshareholdermeeting.com/GRAL2025 and entering the 16-digit control number included in your Internet Notice, on your proxy card or on the instructions that accompanied your proxy materials. The meeting webcast will begin promptly at 4:00 p.m., Eastern Time on May 29, 2025.

Beneficial Owners

If your shares are held in street name through a bank or broker, you will receive instructions on how to vote from the bank or broker. You must follow their instructions in order for your shares to be voted. Internet and telephone voting also may be offered to stockholders owning shares through certain banks and brokers. If your shares are held in street name and you would like to vote at the Annual Meeting, you may visit www.virtualshareholdermeeting.com/GRAL2025 and enter the 16-digit control number included in the voting instruction card provided to you by your bank or brokerage firm. If you hold your shares in street name and you did not receive a 16-digit control number, you may need to log in to your bank or brokerage firm’s website and select the stockholder communications mailbox to access the meeting and vote. Instructions should also be provided on the voting instruction card provided by your bank or brokerage firm.

CAN I CHANGE MY VOTE AFTER I SUBMIT MY PROXY?

Yes.

If you are a registered stockholder, you may revoke your proxy or change your vote:

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

•by granting a subsequent proxy through the Internet or telephone;

•by giving written notice of revocation to the Secretary prior to the Annual Meeting; or

•by attending and voting during the Annual Meeting live webcast.

Your most recent proxy card or Internet or telephone proxy is the one that is counted. Your attendance at the Annual Meeting by itself will not revoke your proxy unless you give written notice of revocation to the Secretary before your proxy is voted or you vote at the Annual Meeting.

If your shares are held in street name, you may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker, or you may vote at the Annual Meeting by following the procedures described above.

WHO WILL COUNT THE VOTES?

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

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

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

WILL ANY OTHER BUSINESS BE CONDUCTED AT THE ANNUAL MEETING?

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

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



PROPOSAL	Votes required	Effect of Votes Withheld / Abstentions and Broker Non-Votes


PROPOSAL 1: ELECTION OF DIRECTORS	The plurality of the votes cast. This means that the nominee receiving the highest number of affirmative “FOR” votes will be elected as a Class I Director.	Votes withheld and broker non-votes will have no effect.


PROPOSAL 2: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM	The affirmative vote of the holders of a majority in voting power of the votes cast (excluding abstentions and broker non-votes).	Abstentions and broker non-votes will have no effect. We do not expect any broker non-votes on this proposal.

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

A “vote withheld,” in the case of the proposal regarding the election of directors, or an “abstention,” in the case of the proposal regarding the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, represents a stockholder’s affirmative choice to decline to vote on a proposal. Votes withheld and abstentions are counted as present and entitled to vote for purposes of determining a quorum. Votes withheld have no effect on the election of directors. Abstentions have no effect on the ratification of the appointment of Ernst & Young LLP.

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

Generally, broker non-votes occur when shares held by a broker in “street name” for a beneficial owner are not voted with respect to a particular proposal because the broker (1) has not received voting instructions from the beneficial owner and (2) lacks discretionary voting power to vote those shares. A broker is entitled to vote shares held for a beneficial owner on routine matters, such as the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, without instructions from the beneficial owner of those shares. On the other hand, the proposal regarding the election of directors is a non-routine matter and, absent instructions from the beneficial owner of such shares, a broker is not entitled to vote shares held for a beneficial owner on such matters. Broker non-votes count for purposes of determining whether a quorum is present.

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

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

PROPOSALS TO BE VOTED ON

PROPOSAL 1 ELECTION OF DIRECTORS

At the Annual Meeting, one Class I Director is to be elected to hold office until the Annual Meeting of Stockholders to be held in 2028 and until such director’s successor is duly elected and qualified or until such director’s earlier death, resignation or removal.

We currently have five directors on our Board. Our Board of Directors is currently divided into three classes with staggered, three-year terms. At each annual meeting of stockholders, the successor to each director whose term then expires will be elected to serve from the time of election and qualification until the third annual meeting of stockholders following election or such director’s death, resignation or removal, whichever is earliest to occur.

The current class structure is as follows:

•Class I, whose term currently expires at the Annual Meeting and, if elected at the Annual Meeting, whose subsequent term will expire at the 2028 Annual Meeting of Stockholders;

•Class II, whose term will expire at the 2026 Annual Meeting of Stockholders; and

•Class III, whose term will expire at the 2027 Annual Meeting of Stockholders.

The current Class I Director is William (Bill) Chase; the current Class II Directors are Steven Mizell and Sarah Krevans; and the current Class III Directors are Gregory (Greg) Summe and Robert Ragusa.

Our Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws provide that the total number of directors constituting the Board shall be determined from time to time by resolution of the Board. Any newly created directorships resulting from any increase in the authorized number of directors shall be filled solely by a majority of the directors then in office, even if less than a quorum, or by a sole remaining director, and shall not be filled by the stockholders unless the Board determines that such newly created directorship or vacancy will be filled by the stockholders.

If you submit a proxy but do not indicate any voting instructions, the persons named as proxies will vote the shares of common stock represented by the proxy for the election of the Class I director named below. The persons whose name and biography appears below is currently serving as our directors. In the event the nominee should become unable to serve or for good cause will not serve as a director, it is intended that votes will be cast for a substitute nominee designated by the Board of Directors or the Board may elect to reduce its size. The Board of Directors has no reason to believe that the nominee named below will be unable to serve if elected. The nominee has consented to being named in this proxy statement and to serve if elected.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors unanimously recommends a vote FOR the election of the below Class I Director nominee.

CLASS I DIRECTOR NOMINEE (SUBSEQUENT TERM TO EXPIRE AT THE 2028 ANNUAL MEETING)

The nominee for election to the Board of Directors as a Class I Director is as follows:


Name	Age	Served as a Director Since	Positions with GRAIL

William (Bill) Chase	57	2024	Director

The principal occupations and business experience of the Class I Director nominee is as follows:

William (Bill) Chase has served as a member of our Board since June 2024. Mr. Chase most recently served for 7 years in roles as Executive Vice President, Finance and Administration and Executive Vice President and Chief Financial Officer at AbbVie Inc. (“AbbVie”) from October 2018 until July 2019, where he oversaw all financial, investor, and IT activities and played a critical role in the development of the company’s strategy and licensing and acquisition actions. Prior to AbbVie, Mr. Chase served nearly 25 years in positions of increasing responsibility at Abbott Laboratories, including roles as Corporate Vice President, Licensing & Acquisitions, Corporate Vice President and Treasurer, and Controller, Abbott International. He currently serves as a director and as chair of the audit committee on the boards of each of Intellia Therapeutics, Inc., a publicly-traded biotechnology company, since April 2023, and Parexel International, a privately-held biopharmaceutical services company, since November 2021. Mr. Chase holds a B.S. from the University of Illinois and an M.B.A. from the University of Chicago Booth School of Business. We believe that Mr. Chase is qualified to serve as a member of our board of directors because of his extensive experience in the biotechnology and pharmaceutical industry and his extensive financial and accounting experience.

CONTINUING MEMBERS OF THE BOARD OF DIRECTORS:

CLASS II DIRECTORS (TERMS TO EXPIRE AT THE 2026 ANNUAL MEETING)

The current members of the Board of Directors who are Class II Directors are as follows:


Name	Age	Served as a Director Since	Positions with GRAIL

Sarah Krevans	66	2024	Director
Steven Mizell	65	2024	Director

The principal occupations and business experience of each Class II Director are as follows:

Sarah Krevans has served as a member of our Board since October 21, 2024. Ms. Krevans is the former President and CEO of Sutter Health, a Northern California based not-for-profit, where she served as CEO from 2016 until 2022. She was responsible for Sutter Health’s integrated network of 14,000 clinicians, 24 hospitals, outpatient services, research facilities, and home health and hospice care. Previously, Ms. Krevans served as chief operating officer and president of the Sutter Health Sacramento Sierra Region.

We believe that Ms. Krevans is qualified to serve as a member of our board of directors because of her experience in U.S. healthcare delivery systems and her extensive industry and leadership experience.

PROPOSAL 2 RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our Audit Committee has appointed Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025. Our Board has directed that this appointment be submitted to our stockholders for ratification. Although ratification of our appointment of Ernst & Young LLP is not required, we value the opinions of our stockholders and believe that stockholder ratification of our appointment is a good corporate governance practice.

Ernst & Young LLP has served as our independent registered public accounting firm since 2023. Neither the accounting firm nor any of its members has any direct or indirect financial interest in or any connection with us in any capacity other than as our auditors, providing audit and non-audit related services. A representative of Ernst & Young LLP is expected to attend the Annual Meeting via live webcast, to have an opportunity to make a statement if desired, and to be available to respond to appropriate questions from stockholders.

In the event that the appointment of Ernst & Young LLP is not ratified by the stockholders, the Audit Committee may reconsider its selection. Even if the appointment of Ernst & Young LLP is ratified, the Audit Committee retains the discretion to appoint a different independent auditor at any time if it determines that such a change is in the interests of the Company.

RECOMMENDATION OF THE BOARD OF DIRECTORS

The Board of Directors unanimously recommends a vote FOR the Ratification of the Appointment of Ernst & Young LLP as our Independent Registered Public Accounting Firm.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The Audit Committee has reviewed the audited consolidated financial statements of GRAIL, Inc., a Delaware corporation (the “Company”) for the fiscal year ended December 31, 2024 and has discussed these financial statements with management and the Company’s independent registered public accounting firm. The Audit Committee has also received from, and discussed with, the Company’s independent registered public accounting firm various communications that such independent registered public accounting firm is required to provide to the Audit Committee, including the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the Securities and Exchange Commission.

The Company’s independent registered public accounting firm also provided the Audit Committee with a formal written statement required by PCAOB Rule 3526 (Communications with Audit Committees Concerning Independence) describing all relationships between the independent registered public accounting firm and the Company, including the disclosures required by the applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence. In addition, the Audit Committee discussed with the independent registered public accounting firm its independence from the Company.

Based on its discussions with management and the independent registered public accounting firm, and its review of the representations and information provided by management and the independent registered public accounting firm, the Audit Committee recommended to the Board of Directors that the audited consolidated financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FEES AND OTHER MATTERS

The following table summarizes the fees of Ernst & Young LLP, our independent registered public accounting firm, billed to us following the Spin-Off:


Fee Category			Fiscal 2024 ($)1

Audit Fees			1,577,929
Audit-Related Fees			-
Tax Fees			-
All Other Fees			-
Total Fees			1,577,929

1 Prior to the Spin-Off, our audit, audit-related, tax, and all other fees were paid by Illumina and reflected in Illumina’s consolidated financial statements.

AUDIT FEES

Audit fees in 2024 consist of fees related to the audit of the annual consolidated financial statements and the review of our interim financial statements.

AUDIT-RELATED FEES

Audit-related fees consist of fees for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements.

TAX FEES

Tax fees consist of fees for tax compliance services and related tax studies.

ALL OTHER FEES

All other fees consist of fees for other permissible work performed by Ernst & Young LLP that does not fall within the categories set forth above.

AUDIT COMMITTEE PRE-APPROVAL POLICY AND PROCEDURES

The Audit Committee has adopted a policy, or the Pre-Approval Policy, that sets forth the procedures and conditions pursuant to which audit and non-audit services proposed to be performed by the independent auditor may be pre-approved. The Pre-Approval Policy generally provides that we will not engage Ernst & Young LLP to render any audit, audit-related, tax or permissible non-audit service unless the service is either (i) explicitly approved by the Audit Committee, or specific pre-approval, or (ii) entered into pursuant to the pre-approval policies and procedures described in the Pre-Approval Policy, or general pre-approval. Unless a type of service to be provided by Ernst & Young LLP has received general pre-approval under the Pre-Approval Policy, it requires specific pre-approval by the Audit Committee or by a designated member of the Audit Committee to whom the Committee has delegated the authority to grant pre-approvals. Any proposed services exceeding pre-approved cost levels or budgeted amounts will also require specific pre-approval. For both types of pre-approval, the Audit Committee will consider whether such services are consistent with the SEC’s rules on auditor independence. The Audit Committee will also consider whether the independent auditor is best positioned to provide the most effective and efficient service, for reasons such as its familiarity with the Company’s business, people, culture, accounting systems, risk profile and other factors, and whether the service might enhance the Company’s ability to manage or control risk or improve audit quality. All such factors will be considered as a whole, and no one factor should necessarily be determinative. The Audit Committee may revise the list of general pre-approved services from time to time, based on subsequent determinations. The Audit Committee pre-approved all services performed since the Pre-Approval Policy was adopted.

CORPORATE GOVERNANCE

General

Our Board of Directors has adopted Corporate Governance Guidelines, a Code of Conduct and charters for our Nominating and Corporate Governance Committee, Audit Committee and Compensation Committee to assist the Board in the exercise of its responsibilities and to serve as a framework for the effective governance of GRAIL. You can access our current committee charters, our Corporate Governance Guidelines and our Code of Conduct in the “Governance” section of our Investor Relations website located at https://investors.grail.com/, or by writing to our Secretary at our offices at 1525 O’Brien Drive, Menlo Park, California 94025.

Board Composition

Our Board of Directors currently consists of five members and is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors are divided among the three classes as follows:

•the Class I director is William (Bill) Chase and his term expires at the Annual Meeting;

•the Class II directors are Sarah Krevans and Steven Mizell, and their terms will expire at our 2026 annual meeting of stockholders; and

•the Class III directors are Gregory (Greg) Summe and Robert Ragusa, and their terms will expire at our 2027 annual meeting of stockholders.

Each director is to hold office until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so as to maintain the number of directors in each class as nearly equal as possible. The division of our Board of Directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control. Our directors may be removed only for cause by the affirmative vote of the holders of at least two-thirds in voting power of the then outstanding shares of our capital stock entitled to vote in the election of directors.

Director Independence

William (Bill) Chase, Sarah Krevans, Steven Mizell and Gregory (Greg) Summe each qualify as “independent” in accordance with the listing requirements of Nasdaq. The Nasdaq independence definition includes a series of objective tests, including that the director is not, and has not been for at least three years, one of our employees and that neither the director nor any of his family members has engaged in various types of business dealings with us. In addition, as required by Nasdaq rules, our Board of Directors has made a subjective determination as to each independent director and director nominee that no relationships exist, which, in the opinion of our Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our Board of Directors reviewed and discussed information provided by the directors and director nominee and us with regard to each individual’s business and personal activities and relationships as they may relate to us and our management. There are no family relationships among any of our directors or executive officers.

Director Candidates

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

To facilitate the search process for director candidates, the Nominating and Corporate Governance Committee may solicit our current directors and executives for the names of potentially qualified candidates or may ask directors and executives to pursue their own business contacts for the names of potentially qualified candidates. The Nominating and Corporate Governance Committee may also consult with outside advisors or retain search firms to assist in the search for qualified candidates, or consider director candidates recommended by our stockholders. William (Bill) Chase was initially recommend to our Board by Heidrick & Struggles International, Inc., an executive search firm.

Once potential candidates are identified, the Nominating and Corporate Governance Committee reviews the backgrounds of those candidates, evaluates candidates’ independence from us and potential conflicts of interest and determines if candidates meet the qualifications desired by the Committee of candidates for election as director.

In accordance with our Corporate Governance Guidelines, in evaluating the suitability of individual candidates, the Nominating and Corporate Governance Committee will consider candidates with personal and professional integrity, strong ethics, values and the ability to make mature business judgments. In evaluating director candidates, the Nominating and Corporate Governance Committee may consider, among others criteria: experience in corporate management, such as serving as an officer or former officer of a publicly held company; experience as a board member of another publicly held company; professional and academic experience relevant to the Company’s industry; leadership skills; any specialized experience; experience in finance and accounting and/or executive compensation practices; and whether the candidate has the time required for preparation, participation and attendance at Board meetings and committee meetings, if applicable. Our Corporate Governance Guidelines provide that the Board will also consider whether there are potential conflicts of interest with the candidate’s other personal and professional pursuits. The Board monitors the mix of specific experience, qualifications, and skills of its directors in order to assure that the Board, as a whole, has the necessary tools to perform its oversight function effectively in light of GRAIL’s business and structure.

Stockholders may recommend individuals to the Nominating and Corporate Governance Committee for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Nominating and Corporate Governance Committee, c/o Secretary, GRAIL, Inc., 1525 O’Brien Drive, Menlo Park, California 94025. In the event there is a vacancy, and assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

Communications from Stockholders

The Board will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Our Secretary is primarily responsible for monitoring communications from stockholders and for providing copies or summaries to the directors as she considers appropriate.

Communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that our Secretary and Chair of the Board consider to be important for the directors to know. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications. Stockholders who wish to send communications on any topic to the Board should address such communications to the Board of Directors in writing: c/o Secretary, GRAIL, Inc., 1525 O’Brien Drive, Menlo Park, California, 94025.

Compensation Committee Interlocks and Insider Participation

Our Compensation Committee consists of William (Bill) Chase, Sarah Krevans, Steven Mizell, and Gregory (Greg) Summe. The chair of our Compensation Committee is Steven Mizell. None of the members of our Compensation Committee is currently or has been at any time one of our officers or employees. None of our executive officers 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 executive officers serving as a member of our Board of Directors or Compensation Committee.

Board Leadership Structure and Role in Risk Oversight

Our Amended and Restated Bylaws and Corporate Governance Guidelines provide our Board of Directors with flexibility to combine or separate the positions of Chair of the Board and Chief Executive Officer in accordance with its determination that utilizing one or the other structure would be in the best interests of our Company. We currently have a non-employee Chair of the Board and a majority of our Board is comprised of independent directors. Our Board believes that separation of the positions of Chair and Chief Executive Officer, combined with the independent leadership of each of our Board committees, reinforces the independence of the Board from management, creates an environment that encourages

objective oversight of management’s performance and enhances the effectiveness of the Board as a whole. For these reasons, our Board of Directors has concluded that our current leadership structure is appropriate at this time.

However, our Board of Directors will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate. Our Corporate Governance Guidelines provide that, where the Chair of the Board is a member of management or not independent, the independent directors may elect a Lead Director. If appointed, the Lead Director’s responsibilities would include, but are not limited to, presiding over all meetings of the Board at which the Chair of the Board is not present, including any executive sessions of the independent directors; approving Board meeting schedules and agendas; and acting as the liaison between the independent directors and the Chief Executive Officer and Chair of the Board.

Risk assessment and oversight are an integral part of our governance and management processes. Our Board of Directors encourages management to promote a culture that incorporates risk management into our corporate strategy and day-to-day business operations. Management discusses strategic and operational risks at regular management meetings and conducts specific strategic planning and review sessions during the year that include a focused discussion and analysis of the risks facing us. Throughout the year, senior management reviews these risks with the Board of Directors at regular Board meetings as part of management presentations that focus on particular business functions, operations or strategies, and presents the steps taken by management to mitigate or eliminate such risks. Our Board of Directors does not have a standing risk management committee, but rather administers this oversight function directly through the Board of Directors as a whole, as well as through various standing committees of the Board of Directors that address risks inherent in their respective areas of oversight. In particular, our Board of Directors is responsible for monitoring and assessing strategic risk exposure and our Audit Committee is responsible for reviewing our policies and practices with respect to risk assessment and risk management, including discussing with management GRAIL’s major financial risk exposures and the steps that have been taken to monitor and control such exposures. The Audit Committee also reviews our cybersecurity and other information technology risks, controls, and procedures, including GRAIL’s plan to mitigate cybersecurity risks and respond to data breaches. The Audit Committee also reviews with management any specific cybersecurity issues that could affect the adequacy of GRAIL’s internal controls. The Audit Committee also monitors compliance with legal and regulatory requirements and considers and approves or disapproves any related person transactions. Our Nominating and Corporate Governance Committee monitors reviews and assesses the adequacy of our Corporate Governance Guidelines. Our Compensation Committee assesses and monitors whether any of our compensation policies and programs have the potential to encourage excessive risk-taking. The Board does not believe that its role in the oversight of our risks affect the Board’s leadership structure.

Code of Ethics

We have a written Code of Business Conduct and Ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. We have posted a current copy of the Code of Business Conduct and Ethics on our website, https://investors.grail.com/corporate-governance/governance-overview. In addition, we intend to post on our website all disclosures that are required by law or the rules of Nasdaq concerning any amendments to, or waivers from, any provision of the Code of Business Conduct and Ethics.

Insider Trading Compliance Policy

The Company has an Insider Trading Compliance Policy and Procedures (the “Insider Trading Policy”) governing the purchase, sale and other dispositions of the Company’s securities that applies to all Company personnel, including directors, officers, employees, and other covered persons. The Company believes that its Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. The policy prohibits our directors, officers and employees and any entities they control from enter into hedging transactions that involve the Company’s securities, such as prepaid variable forward contracts, equity swaps, collars, and exchange funds, or other transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s equity securities. The Insider Trading Policy was filed as Exhibit 19.1 to our Annual Report on Form 10-K for the year ended December 31, 2024.

Attendance by Members of the Board of Directors at Meetings

There were five meetings of the Board of Directors during the fiscal year ended December 31, 2024. During the fiscal year ended December 31, 2024, each director attended all meetings of the Board of Directors and all meetings of the committees on which the director served during the period in which he or she served as a director.

Under our Corporate Governance Guidelines, which are available on our website at https://investors.grail.com/corporate-governance/governance-overview, GRAIL expects directors to be active and engaged in discharging their duties and to keep themselves informed about the business and operations of GRAIL. Directors are expected to attend all Board meetings and the meetings of the committees on which they serve and to prepare themselves for these meetings. We do not maintain a formal policy regarding director attendance at the Annual Meeting; however, directors are encouraged to attend. Due to the timing of our Spin-Off, we did not hold an annual meeting of stockholders in 2024.

Committees of the Board

Our Board of Directors has established an Audit Committee, a Compensation Committee, and a Nominating and Corporate Governance Committee. The composition and responsibilities of each of the Committees of our Board of Directors are described below. Our Board of Directors may establish other committees as it deems necessary or appropriate from time to time. The members of each of the Board committees are set forth in the following chart.

("Compensia"), a compensation consulting firm, to assist in making decisions regarding the amount and types of compensation to provide our executive officers and non-employee directors. Compensia reports directly to the Compensation Committee. The Compensation Committee has considered the adviser independence factors required under SEC rules as they relate to Pay Governance and has determined that Compensia’s work does not raise a conflict of interest.

Our Clawback Policy is attached as an exhibit to our Annual Report on Form 10-K.

Equity Award Timing Policies and Practices

Non-Employee Director Compensation Program

We maintain a compensation program (the “Director Compensation Program”) for our non-employee directors (each, an “Eligible Director”) that consists of annual cash retainer fees and long-term equity awards. Directors who are also full-time officers or employees of our Company receive no additional compensation for serving as directors. The material terms of the Director Compensation Program are summarized below.

The Director Compensation Program consists of the following components for Eligible Directors:

Cash Compensation

•Annual Retainer: $50,000

•Annual Committee Chair Retainers:

•Audit Committee: $20,000

•Compensation Committee: $15,000

•Nominating and Governance Committee: $10,000

•Annual Non-Chair Committee Member Retainers:

•Audit Committee: $10,000

•Compensation Committee: $7,500

•Nominating and Governance Committee: $5,000

•Non-Executive Board Chair Additional Retainer: $50,000

•Lead Independent Director Additional Retainer: $35,000 (We did not have a lead independent director in 2024 because our Chairperson of the Board, Mr. Summe, is an independent director.)

Annual cash retainers are paid in quarterly installments in arrears and will be pro-rated for any partial calendar quarter of service.

Equity Compensation

•Initial Award: Each Eligible Director who is initially elected or appointed to serve on the Board is granted an award of RSUs at the time of the election or appointment with a value of approximately $450,000. Each such initial grant vests as to one-third of the RSUs subject to the award on each of the first three anniversaries of the Eligible Director’s election or appointment date (as applicable), subject to the Eligible Director’s continued Board service through the applicable vesting date.

•Annual Award: Each Eligible Director who is serving on the Board as of the date of an annual meeting of our stockholders is granted, on such annual meeting date, an award of RSUs with a value of approximately $250,000 (pro-rated for each Eligible Director who has served on the Board for less than six months, based on the number of days of such Eligible Director’s Board service through and including the annual meeting date), which vest in full on the earlier to occur of (i) the one-year anniversary of the applicable grant date and (ii) the date of the next annual meeting of the our stockholders, subject to the Eligible Director’s continued Board service through the applicable vesting date.

In addition, each equity award granted to an Eligible Director under the Director Compensation Program will vest in full immediately prior to the occurrence of a “change in control” (within the meaning of the 2024 Plan (as defined below)), to the extent the Eligible Director will not become, as of immediately following such change in control, a board member of the Company or its ultimate parent company.

Compensation under the Director Compensation Program is subject to the annual limits on non-employee director compensation set forth in the 2024 Plan.

Deferred Compensation Plan for Directors

In July 2024, the Board adopted a deferred compensation plan for non-employee directors (the “Director Deferred Compensation Plan”), effective as of July 15, 2024, pursuant to which the Company’s non-employee directors are permitted to defer payment of all or a portion of their annual cash retainers (including any cash retainers for service on a committee) and/or RSU awards in accordance with the terms of the Director Deferred Compensation Plan.

Executive Compensation

(1)The amounts shown in this column for 2024 represent the grant date fair values of (i) Cash-Based Equity Awards granted in 2024, which were converted into RSUs in connection with the Spin-Off and (ii) RSUs granted in 2024, as computed in accordance with Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 718, rather than the amounts paid to or realized by the named individual. The grant date fair value of the Cash-Based Equity awards was the nominal value of the award and the grant date fair value of the RSU awards was based on the closing price of a share of our common stock on the Nasdaq Stock Market LLC on the date of grant.

(2)With respect to 2024, amounts represent annual bonuses earned by each NEO in 2024 and paid in cash in 2025 under our VCP (discussed below under “2024 Annual Bonuses (Non-Equity Incentive Plan Awards)”), based on the attainment of pre-determined company performance metrics.

(3)Amounts in this column include the following for 2024: (i) for Mr. Ragusa: $3,000 in 401(k) plan matching contributions, $8,400 in Company-provided dues for a membership in connection with a 2024 marketing event, $9,098 for travel and expenses paid on behalf of Mr. Ragusa and his spouse to attend a sales incentive event and $19,853 in payments made to offset taxes imposed on Mr. Ragusa with respect to these dues and travel expenses; (ii) for Mr. Freidin: $3,000 in 401(k) plan matching contributions; (iii) for Mr. Ofman: $3,000 in 401(k) plan matching contributions, $9,170 for travel and expenses paid on behalf of Mr. Ofman and his spouse to attend a sales incentive event, $50,692 in payments made to Mr. Ofman to offset his rent expense in 2024 (as contemplated by his initial offer of employment, the Company provides Mr. Ofman with a housing allowance to enable him to spend time at the Company’s headquarters in Menlo Park) and $24,933 in payments made to Mr. Ofman to offset taxes imposed on him with respect to his travel expense and Company-paid housing benefit.

2024 Salaries

Following an analysis of our market positioning against peers and in alignment with our overall compensation philosophy, we determined to make no changes to the base salary for our NEOs in 2024 as compared to 2023. In March 2023, each of our NEOs received a merit-based increase in base salary. Accordingly, the amount of salary actually paid to each of our NEOs increased in 2024 as compared to 2023 due to having the increased base salary effective for a full year. The annual base salaries for Robert Ragusa, Aaron Freidin, and Josh Ofman for 2024 were $785,000, $560,000, and $655,000, respectively.

2024 Annual Bonuses (Non-Equity Incentive Plan Awards)

Our annual Variable Compensation Program (“VCP”) provides our eligible employees, including our NEOs, with the opportunity to earn annual cash bonuses based on the achievement of pre-established corporate goals for the applicable fiscal year. Corporate goals included Galleri and other revenue targets, premarket approval application and reimbursement milestones, clinical study execution, product and platform improvements, cash conservation and others. Individual VCP targets are determined based on each individual’s role, taking into consideration an analysis of peer data for comparable roles. 2024 target bonus opportunities were unchanged compared to 2023, and were set at 100% of salary for Mr. Ragusa and 50% of salary for Messrs. Freidin and Ofman. The payment of any annual bonus, if earned, is contingent upon the applicable participant’s (i) continued employment or other service with the Company through the applicable payment date, (ii) employment start date commencing on or prior to October 1 of the applicable fiscal year and (iii) continued compliance with Company policy and applicable law.

Equity and Equity-Linked Compensation

Prior to the Spin-Off, each of our NEOs was granted cash-based equity appreciation incentive awards (“Cash-Based Equity Awards”), which were dollar-denominated, long-term incentive awards that increased or decreased in value based on corresponding changes in our aggregate equity value. The Cash-Based Equity Awards generally vested incrementally over a four-year period with twenty-five percent (25%) of the award vesting on each of the first four anniversaries of the vesting

commencement date, subject to continued employment through the applicable vesting date. Until April 30, 2024, our aggregate equity value was estimated by the Company based on its analysis and the input from independent valuation advisors. In April 2024, Illumina’s Compensation Committee and Board of Directors approved an adjustment of the ordinary course payouts for all outstanding Cash-Based Equity Awards to provide that the portion of the Cash-Based Equity Awards payable after April 30 in 2024 would be paid based on their nominal (face) values without adjustment based on changes in equity value.

Also, in April 2024, each of our NEOs was granted a one-time cash-based incentive award for retention purposes (“2024 Transition Retention Awards”) to foster leadership team stability through the Spin-Off, which was dollar-denominated and vests in full on the first anniversary of the grant date, subject to the applicable NEO’s continued employment through the applicable vesting date.

If we experience a “change in control” (as provided in the applicable agreements), (i) the Cash-Based Equity Awards provide for continuation on their terms unless the Cash-Based Equity Awards are not continued, assumed, substituted for or converted into an award of substantially equivalent value in connection with such change in control, in which case the Cash-Based Equity Awards will vest and be paid upon such change in control, and (ii) the 2024 Transition Retention Awards provide for continuation on their terms. If, following a change in control, the recipient's continued service is terminated by us or our affiliates without cause or by the recipient with good reason (as each term is defined in the 2024 Transition Retention Award agreement), the 2024 Transition Retention Award will become fully vested. Additional change in control terms applicable to these awards are described below under “ —Executive Compensation Arrangements—Offer Letters and Separation and General Release Agreement.”

In connection with the Spin-Off, outstanding Cash-Based Equity Awards and 2024 Transition Incentive Awards were converted into RSUs (the “RSU Conversion” and the awards, “Converted Awards”) under our 2024 Plan that settle in shares of our common stock upon or shortly after vesting in accordance with the Employee Matters Agreement, dated June 24, 2024, by and between us and Illumina (the “Employee Matters Agreement”). The outstanding Cash-Based Equity Awards were first converted into RSUs that settle in shares of Illumina Stock (“Illumina RSUs”) and then immediately into RSUs under our 2024 Plan. The outstanding 2024 Transition Incentive Awards were converted directly into RSUs under our 2024 Plan. The the number of RSUs subject to each converted Cash-Based Equity Award and 2024 Transition Incentive Award was determined as follows (without giving effect to immaterial differences resulting from the intermediate conversion of the Cash-Based Equity Awards into Illumina RSUs): (i) for Cash-Based Equity Awards, by dividing the Aggregate Award Value (as defined below) by the volume-weighted average share price over the first four trading days following the Spin-Off and (ii) for the 2024 Transition Incentive Awards, by dividing the nominal (face) value of the 2024 Transition Incentive Award by the volume-weighted average share price over the first four trading days following the Spin-Off. For each Cash-Based Equity Award, the “Aggregate Award Value” was equal to (i) for the portion of such Cash-Based Equity Award originally scheduled to vest in 2024, the initial grant value of such portion, and (ii) for the remaining unvested portion of such Cash-Based Equity Award, the initial grant value of such portion adjusted up or down based on a percentage, with such percentage determined by dividing: (A) GRAIL’s average closing market capitalization for the four trading days immediately following the distribution date, minus the aggregate equity value of GRAIL at the time the Cash-Based Equity Award was granted, as reflected in the consolidated financial statements of Illumina (the “Baseline Equity Value”), by (B) the applicable Baseline Equity Value. In connection with the Spin-Off, other terms and conditions of the Cash-Based Equity Awards and 2024 Transition Incentive Awards, including change in control, vesting and payment terms, were generally unaffected by the RSU Conversion.

In connection with the Spin-Off, our board of directors adopted and Illumina, as our sole stockholder, approved the 2024 Incentive Award Plan (the “2024 Plan”), in order to facilitate the grant of cash and equity incentives to directors, employees (including our NEOs) and consultants of our Company and certain of our subsidiaries and to enable our Company and certain of our subsidiaries to obtain and retain services of these individuals following the Spin-Off, which we view as essential to our long-term success.

Following the Spin-Off, our Compensation Committee recognized that as a result of the valuation of the Company in the Spin-Off and the resultant impact on the conversion described above, the value of the Converted Awards was substantially lower than the nominal (face) value of the awards prior to the Spin-Off. The Compensation Committee determined that additional equity grants to our NEOs and others were appropriate to provide increased retention to the NEOs to remain employed through the achievement of key corporate goals. On October 3, 2024, each of our NEOs was granted two awards of RSUs under the 2024 Plan: (i) one award vesting in full on the 18-month anniversary of the grant date and (ii) one

award vesting, with respect to Mr. Ofman, on the 12-month anniversary of the grant date and, with respect to Mr. Ragusa and Mr. Freidin, on the 24-month anniversary of the grant date, in all cases, subject to the applicable NEO’s continued employment through the applicable vesting date (these awards together, the “2024 Post-Spin-Off Equity Awards”).

For additional information about these awards, please see the sections titled “—Outstanding Equity Awards at Fiscal Year End” and “—Executive Compensation Arrangements” below.

Other Elements of Compensation

Retirement Plans

We maintain a tax-qualified 401(k) retirement savings plan for our employees, including our NEOs, who satisfy certain eligibility requirements. Our NEOs are eligible to participate in the 401(k) plan on the same terms generally applicable to other eligible, full-time employees. The Internal Revenue Code of 1986, as amended, and the regulations issued thereunder (the “Code”) allow eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. In 2024, we made matching contributions under our 401(k) plan, including for the NEOs, up to a specified percentage of employee contributions and a maximum of $3,000 per employee. These matching contributions vest in full after one year of service. We believe that providing a vehicle for tax-deferred retirement savings through our 401(k) plan adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our NEOs, in accordance with our compensation goals.

Employee Benefits and Perquisites

Health/Welfare Plans. All of our full-time employees, including our NEOs, are eligible to participate in our health and welfare plans, including:

•medical, dental, and vision benefits;

•medical and dependent care flexible spending accounts;

•short-term and long-term disability insurance;

•wellbeing benefits (including mental health, back-up care and family forming benefits); and

•life insurance.

We believe the benefits described above are in line with market practice and necessary and appropriate to provide a competitive compensation package to our NEOs. We do not provide any other executive-specific perquisites.

No IRC Section 280G “Golden Parachute” Tax Gross-Ups

Except for tax gross-up payments (i) in the amount of $24,933 in 2024 paid to Mr. Ofman to offset taxes imposed on him with respect to his Company-paid housing benefit and his and his spouse’s attendance at a sales incentive event and (ii) in the amount of $19,853 in 2024 paid to Mr. Ragusa to offset taxes imposed on him with respect to his Company-paid dues and his and his spouse’s attendance at a sales incentive event, we do not make gross-up payments to cover our NEOs’ personal income taxes that may pertain to any of the compensation or perquisites paid or provided by our company. Without limiting the foregoing, we have not paid, and have no obligation to pay, any tax gross-ups with respect to any excise taxes that may be imposed under or by operation of the Internal Revenue Code Section 280G “golden parachute” rules.

Mr. Ofman’s relocation has not yet occurred and GRAIL has continued to reimburse Mr. Ofman for the cost of rental housing. Effective as of December 15, 2023, GRAIL committed to reimburse Mr. Ofman for up to 50% of Mr. Ofman’s monthly housing rental cost, up to a maximum of $4,438 per month until the later of February 28, 2025 or the date on which Mr. Ofman’s employment with us terminates, and to pay an additional amount to Mr. Ofman to offset the amount of taxes payable by Mr. Ofman as a result of such reimbursement. Effective as of February 1, 2024, we agreed to change the amount of such reimbursement to $4,000 per month and further agreed to reimburse Mr. Ofman for moving expenses associated with vacating his current premises and moving to a new location in accordance with our relocation guidelines.

Pursuant to the offer letter, in the event that Mr. Ofman’s employment is terminated by us without cause or Mr. Ofman resigns for good reason (each as defined in the offer letter), then, in addition to accrued benefits and subject to his timely execution of an effective separation and release agreement in a form prescribed by us, Mr. Ofman will be entitled to receive the following severance payments and benefits: (i) a lump-sum cash payment in an amount equal to nine months of base salary and (ii) reimbursement for the cost of health benefits under COBRA for up to nine months.

In addition, pursuant to the offer letter, in the event that Mr. Ofman’s employment is terminated by us without cause or Mr. Ofman resigns for good reason, in either case, within 12 months following or 3 months preceding a change in control, then Mr. Ofman will instead be entitled to receive the following severance payments and benefits (subject to the same separation and release agreement requirements and in lieu of the amounts described above): (i) a lump-sum cash payment in an amount equal to 12 months of base salary, (ii) a lump-sum cash payment in an amount equal to 100% of Mr. Ofman’s target bonus under the VCP, (iii) reimbursement for the cost of health benefits under COBRA for up to 12 months, and (iv) full accelerated vesting of outstanding and unvested equity awards (with performance vesting awards vesting based on target performance).

Description of the 2024 Inducement Plan

On August 9, 2024, our board of directors adopted the 2024 Employee Inducement Incentive Award Plan, under which we may grant cash and equity incentive awards to eligible employees in order to attract, motivate, and retain the talent for which we compete. The 2024 Inducement Plan is a non-stockholder approved stock plan adopted pursuant to the “inducement exception” provided under Nasdaq Listing Rule 5635(c)(4). The material terms of the 2024 Inducement Plan are summarized below.

Eligibility and Administration. Awards under the 2024 Inducement Plan may only be granted to prospective employees of the Company or one of its subsidiaries who are commencing employment with the Company or such subsidiary, or being rehired following a bona fide period of non-employment by the Company or any of its subsidiaries, if he or she is granted an award in connection with his or her commencement of employment with the Company or any of its subsidiaries and such grant is an inducement material to his or her entering into employment with the Company or such subsidiary. The 2024 Inducement Plan will be administered by our compensation committee; provided that our board of directors may re-vest itself with the authority to administer the 2024 Inducement Plan at any time. The compensation

committee (or board of directors, as applicable) may delegate its duties and responsibilities to committees of our board of directors and/or officers (referred to, collectively, as the plan administrator below). The plan administrator will have the authority to make all determinations and interpretations under, prescribe all forms for use with, and adopt rules for the administration of the 2024 Inducement Plan, subject to its express terms and conditions. The plan administrator will also set the terms and conditions of all awards under the 2024 Inducement Plan, including any vesting and vesting acceleration conditions.

Shares Available. The number of shares available for issuance under the 2024 Inducement Plan is not fixed; rather, the plan administrator may grant awards under the plan to prospective employees as and when it deems appropriate.

Awards. The 2024 Inducement Plan authorizes the grant of non-qualified stock options, SARs, restricted stock, dividend equivalents, restricted stock units (“RSUs”), and other stock- or cash-based awards. Certain awards under the 2024 Inducement Plan may constitute or provide for a deferral of compensation, subject to Section 409A of the Code, which may impose additional requirements on the terms and conditions of such awards. All awards under the 2024 Inducement Plan will be evidenced by award agreements, which will detail all terms and conditions of the awards, including any applicable vesting and payment terms and post-termination exercise limitations. Awards other than cash awards generally will be settled in shares of common stock, but the plan administrator may provide for cash settlement of any award. A brief description of each award type follows.

•Stock Options and SARs. Stock options provide for the purchase of shares of our common stock in the future at an exercise price set on the grant date. SARs entitle their holder, upon exercise, to receive from us an amount equal to the appreciation of the shares subject to the award between the grant date and the exercise date. The exercise price of a stock option or SAR may not be less than 100% of the fair market value of the underlying share on the grant date. The term of a stock option or SAR may not be longer than ten years.

•Restricted Stock. Restricted stock is an award of nontransferable shares of our common stock that are subject to certain vesting conditions and other restrictions.

•RSUs. RSUs are contractual promises to deliver shares of our common stock in the future, which may also remain forfeitable unless and until specified conditions are met and may be accompanied by the right to receive the equivalent value of dividends paid on shares of common stock prior to the delivery of the underlying shares (i.e., dividend equivalent rights). The plan administrator may provide that the delivery of the shares underlying RSUs will be deferred on a mandatory basis or at the election of the participant. The terms and conditions applicable to RSUs will be determined by the plan administrator, subject to the conditions and limitations contained in the 2024 Inducement Plan.

•Other Stock- or Cash-Based Awards. Other stock- or cash-based awards are awards of cash, fully vested shares of our common stock and other awards valued wholly or partially by referring to, or otherwise based on, shares of our common stock. Other stock- or cash-based awards may be granted to participants and may also be available as a payment form in the settlement of other awards, as standalone payments and as payment in lieu of compensation to which a participant is otherwise entitled.

•Dividend Equivalents. Dividend equivalents represent the right to receive the equivalent value of dividends paid on shares of our common stock and may be granted alone or in tandem with awards other than stock options or SARs. Dividend equivalents are credited as of the dividend record dates during the period between the date an award is granted and the date such award vests, is exercised, is distributed, or expires, as determined by the plan administrator. Dividend equivalents are only paid out to the extent that the vesting conditions of the underlying award are subsequently satisfied.

Certain Transactions. The plan administrator has broad discretion to take action under the 2024 Inducement Plan, as well as make adjustments to the terms and conditions of existing and future awards, to prevent the dilution or enlargement of intended benefits and facilitate necessary or desirable changes in the event of certain transactions and events affecting our common stock, such as stock dividends, stock splits, mergers, acquisitions, consolidations, and other corporate transactions. In addition, in the event of certain non-reciprocal transactions with our stockholders known as “equity restructurings,” the plan administrator will make equitable adjustments to the 2024 Inducement Plan and outstanding awards. In the event of a

change in control of our Company (as defined in the 2024 Inducement Plan), to the extent that the surviving entity declines to continue, convert, assume, or replace outstanding awards, then all such awards will become fully vested and exercisable in connection with the transaction. Awards under the 2024 Inducement Plan are generally non-transferrable, except by will or the laws of descent and distribution, or, subject to the plan administrator’s consent, pursuant to a domestic relations order, and are generally exercisable only by the participant.

Foreign Participants, Claw Back Provisions, Transferability, and Participant Payments. The plan administrator may modify award terms, establish subplans and/or adjust other terms and conditions of awards, subject to the share limits described above, in order to facilitate grants of awards subject to the laws and/or stock exchange rules of countries outside of the United States. All awards will be subject to the provisions of any clawback policy implemented by our Company to the extent set forth in such clawback policy and/or in the applicable award agreement. With regard to tax withholding, exercise price, and purchase price obligations arising in connection with awards under the 2024 Inducement Plan, the plan administrator may, in its discretion, accept cash or check, shares of our common stock that meet specified conditions, a “market sell order,” or such other consideration as it deems suitable.

Plan Amendment and Termination. The plan administrator may amend or terminate the 2024 Inducement Plan at any time; however, no amendment, other than an amendment that increases the number of shares available under the 2024 Inducement Plan, may materially and adversely affect an award outstanding under the 2024 Inducement Plan without the consent of the affected participant, and stockholder approval will be obtained for any amendment to the extent necessary to comply with applicable laws or to increase the director limit. The plan administrator will have the authority, without the approval of our stockholders, to “reprice” any stock option or SAR, or cancel any stock option or SAR in exchange for cash or another award when the option or SAR price per share exceeds the fair market value of the underlying shares. The 2024 Inducement Plan will remain in effect until the tenth anniversary of the date the board of directors adopted the 2024 Inducement Plan unless earlier terminated by our board of directors.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information with respect to holdings of our common stock by (i) stockholders who beneficially owned more than 5% of the outstanding shares of our common stock, and (ii) each of our directors (which includes all nominees), each of our named executive officers and all directors (which includes all nominees) and executive officers as a group as of March 31, 2025, unless otherwise indicated. The number of shares beneficially owned by each stockholder is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which a person has sole or shared voting power or investment power. Applicable percentage ownership is based on 35,296,858 shares of common stock outstanding as of March 31, 2025. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of common stock subject to options, or other rights held by such person that are currently exercisable or will become exercisable within 60 days of March 31, 2025 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each beneficial owner listed below is 1525 O’Brien Drive, Menlo Park, California, 94025. We believe, based on information provided to us, that each of the stockholders listed below has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who own more than ten percent of a registered class of our 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. Based solely on the Company’s review of the reports that have been filed by or on behalf of such person in this regard, we believe that all such persons complied with on a timely basis with all Section 16(a) filing requirements during the fiscal year ended December 31, 2024, other than one Form 4 that that was inadvertently filed late for Chun R. Ding and one Form 4 that was inadvertently filed late for Sarah Krevans.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

Policy and Procedures Governing Related Person Transactions

We have a written Related-Persons Transaction Policy that applies to our executive officers, directors, director nominees, holders of more than five percent of any class of our voting securities, and any member of the immediate family of, and any entity affiliated with, any of the foregoing persons. Such persons are not permitted to enter into a related person transaction with us without the prior consent of our Audit Committee, or other independent members of our Board in the event it is inappropriate for our Audit Committee to review such transaction due to a conflict of interest. Any request for us to enter into a transaction with an executive officer, director, director nominee, principal stockholder, or any of their immediate family members or affiliates, in which the amount involved exceeds $120,000, must first be presented to our Audit Committee for review, consideration, and approval. In approving or rejecting any such proposal, our Audit Committee will consider the relevant facts and circumstances available and deemed relevant to our Audit Committee, including, but not limited to, the commercial reasonableness of the terms of the transaction and the materiality and character of the related person’s direct or indirect interest in the transaction.

The following are certain transactions, arrangements and relationships with our directors, executive officers and stockholders owning 5% or more of our outstanding common stock, or any member of the immediate family of any of the foregoing persons, since January 1, 2023, other than equity and other compensation, termination, change in control and other arrangements, which are described under “Executive Compensation.”

On June 24, 2024, (the “Distribution Date”), Illumina completed the previously announced spin-off of GRAIL (the “Spin-Off”). The Spin-Off was completed through a distribution of 85.5% of the Company’s outstanding common stock to the holders of record of Illumina’s common stock as of the close of business on June 13, 2024 (the “Distribution”), which resulted in the distribution of 31.0 million shares of common stock. As a result of the Distribution, the Company became an independent public entity.

Separation and Distribution Agreement

On June 21, 2024, we entered into a separation and distribution agreement (the “Separation and Distribution Agreement”) with Illumina that set forth agreements regarding the principal actions that were taken in connection with the Spin-Off. It also set forth other agreements that govern aspects of our relationship with Illumina following the Spin-Off.

We and Illumina agreed to indemnify the other and each of the other’s former and current directors, officers, and employees, and each of the heirs, executors, successors, and assigns of any of them, against certain liabilities incurred in connection with the Spin-Off and our and Illumina’s respective businesses. The amount of either Illumina’s or our indemnification obligations will be reduced by any insurance proceeds the party being indemnified receives. The Separation and Distribution Agreement also specifies procedures regarding claims subject to indemnification.

Prior to the completion of the Spin-Off, Illumina contributed to us an amount, in cash, so as to cover 2.5 years of our operations based on the projected operating free cash flow set forth in our long range plan (such amount, the “Disposal Funding”). We may be required to return all or a portion of the Disposal Funding to Illumina in the event of certain transactions before the 15-month anniversary of the Distribution Date (the “Restricted Period”). Subject to limited exceptions, if we pay any dividend on, or make any other distribution in respect of, any shares of our common stock or other equity or voting interests (other than a stock dividend or a stock split), or otherwise consummate a return of capital to any of our equityholders or redeem, purchase, or otherwise acquire any of our outstanding shares of common stock or other equity or voting interests during the Restricted Period, then we must return to Illumina the aggregate amount of payments to equityholders as a result of or in connection with such a transaction. Additionally, in connection with certain change of control transactions during the Restricted Period, we must return to Illumina a cash amount calculated by reference to the number of months which have elapsed since the Distribution Date at the time of the public announcement of the event giving rise to the change of control.

Tax Matters Agreement

On June 24, 2024, we and Illumina entered into a tax matters agreement (the “Tax Matters Agreement”) that governs the parties’ respective rights, responsibilities, and obligations after the Distribution with respect to all tax matters (including tax liabilities, tax attributes, tax returns, and tax contests).

The Tax Matters Agreement generally allocates liability for any taxes and related losses resulting from the failure of the Spin-Off and certain related transactions to qualify for their intended tax treatment under U.S. federal income tax law between Illumina and us generally based on which party was responsible for causing such transactions not to qualify for the intended tax treatment, with each party generally responsible for breaches of its own representations and covenants and transactions involving its own stock, provided Illumina generally bears any taxes and losses imposed on Illumina if the retention and disposition of its retained stake in GRAIL cause the Spin-Off to be taxable to Illumina.

The Tax Matters Agreement imposes certain restrictions on us and our subsidiaries (including restrictions on share issuances, redemptions or repurchases, business combinations, sales of assets, and similar transactions) that are designed to address compliance with Section 355 of the Code and preserves the tax-free nature of the Spin-Off. These restrictions apply for the two-year period after the Distribution unless Illumina obtains an opinion from counsel or a ruling from the IRS generally to the effect that a restricted action will not cause the Spin-Off or certain related transactions to fail to qualify for its intended tax treatment, or Illumina gives its consent for us to take a restricted action. These restrictions may limit our ability to pursue strategic transactions or engage in new businesses or other transactions that may maximize the value of our business, and might discourage or delay a strategic transaction that our stockholders may consider favorable.

Employee Matters Agreement

On June 24, 2024, we and Illumina entered into an employee matters agreement (the “Employee Matters Agreement”) that addresses certain employment, compensation, and benefits matters, including the allocation and treatment of certain assets and liabilities relating to our employees and compensation and benefit plans and programs in which our employees participate prior to the Spin-Off.

We generally assumed or retained all employee and benefit plan liabilities with respect to our current or former employees and benefit plans and Illumina generally assumed or retained all employee and benefit liabilities with respect to their current or former employees and benefit plans.

Each outstanding and unvested portion of the Cash-Based Equity Awards as of immediately prior to the Distribution Date was converted into GRAIL RSUs, with the number of shares of GRAIL common stock subject to such GRAIL RSUs equal to (i) the “Aggregate Award Value” (as defined below) for such Cash-Based Equity Award divided by (ii) the average of the volume weighted average per share price of GRAIL Stock on the first four trading days immediately following the Distribution Date (the “GRAIL Share Value”). All other terms and conditions of the awards, including vesting and payment terms, were unaffected by the conversion. The Employee Matters Agreement also provides for an intermediate conversion of the Cash-Based Equity Awards in order to satisfy certain legal requirements under the documentation of the award agreements, but this intermediate conversion does not affect the value of the awards or the number of shares of GRAIL Stock subject to the resulting GRAIL RSUs.

For each Cash-Based Equity Award, the “Aggregate Award Value” is equal to, (i) for the portion of such award originally scheduled to vest in 2024, the initial grant value of such portion, and (ii) for the remaining unvested portion of such award, the initial grant value of such portion adjusted up or down based on a percentage, with such percentage determined by (A) GRAIL’s average closing market capitalization for the four trading days immediately following the Distribution Date minus the aggregate equity value of GRAIL at the time the Cash-Based Equity Award was granted, as reflected in the consolidated financial statements of Illumina (the “Baseline Equity Value”), divided by (B) the Baseline Equity Value.

We also agreed to take all actions that are necessary for us to continue to maintain and comply with any collective bargaining agreements and any pre-existing collective bargaining relationships in respect of any of our UK-based employees and any applicable employee representatives.

Stockholder and Registration Rights Agreement

On June 24, 2024, we and Illumina entered into a stockholder and registration rights agreement (the “Stockholder and Registration Rights Agreement”) pursuant to which we granted to Illumina certain registration rights with respect to the shares of our common stock owned by Illumina. Illumina may transfer these rights in certain limited circumstances, including in connection with an equity-for-debt exchange to a third-party lender (a “Permitted Transferee” and, collectively with Illumina, “Holders”), and such Holders will thereafter be bound by the terms of the Stockholder and Registration Rights Agreement.

Demand Registration

Holders are able to request registration under the Securities Act of all or any portion of their shares of our common stock covered by the Stockholder and Registration Rights Agreement, and we are obligated, subject to limitations on minimum offering size and certain other limited exceptions, to register such shares as requested by such Holders. Holders are generally able to designate the terms of each offering effected pursuant to a demand registration, which may take the form of a shelf registration, and are able to request that we complete up to three demand registrations in any 12-month period, provided that we shall not be obligated to effect more than five demand registration in the aggregate.

We are not required to honor a demand registration if we have effected a registration within the preceding 60 days. In addition, if we reasonably determine in good faith that filing a registration statement would be significantly disadvantageous to us, we may, no more than twice during any 12-month period, delay filing such registration statement until the earlier of 90 days after we make such determination or seven days after the disadvantageous condition no longer exists, provided that these postponement rights shall not be applicable to the Holders for more than a total of 120 days during any 12-month period.

Piggy-Back Registration

If we at any time intend to file on our behalf or on behalf of any of our other security holders a registration statement in connection with a public offering of any of our securities on a form and in a manner that would permit the registration for offer and sale of shares of our common stock held by Holders, Holders have the right to include their shares of our common stock in that offering, subject to certain limitations.

Indemnification

The Stockholder and Registration Rights Agreement contains customary indemnification and contribution provisions by us for the benefit of Holders and, in limited situations, by Holders for the benefit of us with respect to the information provided by such Holders included in any registration statement, prospectus, or related document.

Voting Restrictions

Illumina agreed to vote any shares of our common stock that it retains in proportion to the votes cast by our other stockholders and granted us a proxy to vote its shares of our common stock in such proportion. Any such proxy, however, is automatically revoked as to a particular share upon any sale or transfer of such share from Illumina to a person other than Illumina, and neither the Stockholder and Registration Rights Agreement nor proxy l limits or prohibits any such sale or transfer.

Ongoing Commercial Agreements

In addition to the above agreements, we are also currently party to, or intend to enter into, various other agreements with Illumina and its subsidiaries, including a supply and commercialization agreement and license agreements.

In January 2016, we entered into a supply and commercialization agreement with Illumina. The agreement was amended and restated in February 2017, and subsequently amended in September 2017, August 2021, and May 2023. Under the terms of the agreement, we agreed to pay to Illumina a high single-digit royalty, subject to certain reductions and floors, in perpetuity on net sales generated by our products or revenues otherwise generated or received by us, regardless of whether these products incorporate any Illumina intellectual property, subject to certain exceptions, in the field of oncology. In August 2021, following Illumina’s acquisition of GRAIL, the agreement was amended to suspend the royalty payments for as long as

GRAIL is an affiliate of Illumina. The divestment plan submitted to and approved by the European Commission on April 12, 2024, provides that Illumina agreed to divest GRAIL on specified terms (the “Divestment Plan”). It further permits Illumina to maintain the royalty arrangement with GRAIL. In connection with the separation of GRAIL from Illumina via the Spin-Off, the Supply Agreement was further amended on June 21, 2024 to extend the suspension of the perpetual royalty agreement until the earlier of two-and-a-half years or any earlier change of control of GRAIL, at which time royalty payments to Illumina will resume, without retroactive effect. In addition, we may elect to purchase instruments, supplies, and services from Illumina either pursuant to the Open Offer or the Grandfathered Pricing.

Under the agreement, Illumina granted us non-exclusive rights to use certain Illumina know-how and technology with Illumina products purchased under the agreement, and we granted Illumina an irrevocable, perpetual, worldwide, fully paid-up, and royalty-free license covering improvements to certain Illumina know-how and technology. Pursuant to the agreement, we were also required to develop a small-variant targeted plasma assay and deliver it to Illumina, which we have done. We retain ownership of the intellectual property generated by the development of this assay, and we have granted Illumina an irrevocable, perpetual, non-exclusive license to use any of the intellectual property embodied in this assay, with certain limitations on sublicensing.

The term of the agreement is 10 years, subject to two-year automatic renewal periods unless one of the parties terminates prior to such renewal period; however, the term is limited to a maximum term of 20 years. The agreement may also be terminated by either party for uncured material breach or bankruptcy or insolvency of the other party. Illumina may terminate the agreement if it is notified by any regulatory authority that our performance under the agreement materially violates an applicable law or due to a change of control of GRAIL involving a competitor of Illumina. Upon the termination of the agreement for any reason, the licenses granted to us by Illumina under the agreement would terminate but our licenses to Illumina survive the termination of the agreement. Our royalty payment obligations also survive the termination of this agreement. In February 2019, pursuant to the terms of the supply and commercialization agreement with Illumina, we entered into two separate non-exclusive and non-sublicensable license agreements with Illumina. Under these license agreements, Illumina is required to pay us (i) initial aggregate licensing fees of $50,000, (ii) annual minimum aggregate royalties of $50,000, increasing by $10,000 annually to a maximum of $100,000, and (iii) running royalties in the low percentages of net sales of products utilizing in-licensed technology. In addition, one of the license agreements includes a milestone of $50,000 tied to the first commercial sale of a product covered by a licensed patent.

Illumina is also a customer of the Company, and purchased $460 thousand and $652 thousand of Galleri tests from us in 2024 and 2023, respectively.

Other Arrangements

Prior to the Spin-Off, we have had various other arrangements with Illumina, including arrangements whereby (i) pursuant to the binding Hold Separate Commitments put in place by Illumina and the Transitional Measures imposed by the European Commission, GRAIL has been held and operated separately and independently from Illumina and Illumina funded GRAIL’s operations and (ii) in connection with Illumina’s acquisition of GRAIL in 2021 (the “Acquisition”), Illumina issued to the then-holders of GRAIL common stock and preferred stock, at each holder’s election in lieu of cash consideration otherwise payable in the Acquisition, contingent value rights (“CVRs”) representing the right to receive future cash payments from Illumina on a quarterly basis representing a pro rata portion of certain GRAIL-related revenues. Subject to the terms of the Divestment Plan, Illumina may (i) conduct a tender offer to acquire all issued and outstanding CVRs and, if permitted under the terms of the CVR Agreement, redeem all remaining outstanding CVRs or (ii) retain the CVR liability and continue its obligation to make payments following the Spin-Off. GRAIL does not have any obligation to make payments in respect of the CVRs.

Stockholders intending to present a proposal at the 2026 Annual Meeting of Stockholders, but not to include the proposal in our proxy statement, or to nominate a person for election as a director, must comply with the requirements set forth in our Amended and Restated Bylaws. Our Amended and Restated Bylaws require, among other things, that our Secretary receive written notice from the stockholder of record of their intent to present such proposal or nomination not less than ninety (90) days nor more than one hundred twenty (120) days prior to the one-year anniversary of the preceding year’s annual meeting. Therefore, we must receive notice of such a proposal or nomination for the 2026 Annual Meeting of Stockholders no earlier than January 29, 2026, and no later than February 28, 2026. The notice must contain the information required by the Amended and Restated Bylaws, a copy of which is available upon request to our Secretary. In the event that the date of the 2026 Annual Meeting of Stockholders is more than 30 days before or more than 60 days after May 29, 2026, then our Secretary must receive such written notice not earlier than the close of business on the 120th day prior to the 2026 Annual Meeting and not later than the close of business on the 90th day prior to the 2026 Annual Meeting and the close of business on the 10th day following the day on which public disclosure of the date of such meeting is first made by us.

In addition to satisfying the foregoing requirements under our Amended and Restated Bylaws, 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(b) under the Exchange Act.

We reserve the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with these or other applicable requirements.
