Bradley L. Radoff, The Radoff Family Foundation ("Radoff Foundation" and together with Mr. Radoff, "Radoff"), JEC II Associates, LLC ("JEC II"), The MOS Trust ("MOS Trust"), MOS PTC, LLC ("MOS PTC") and Michael Torok (together with JEC II, MOS Trust and MOS PTC, "JEC" and collectively with Radoff, the "Radoff-JEC Group" or "we") are significant stockholders of Seer, Inc., a Delaware corporation ("Seer" or the "Company"), who, together with the other participants in this solicitation, beneficially own an aggregate of 4,277,528 shares of Class A Common Stock, par value $0.00001 per share (the "Common Stock"), of the Company, representing approximately 7.7% of the outstanding Common Stock. The Radoff-JEC Group has filed a proxy statement (the "Proxy Statement") and accompanying **WHITE** universal proxy card with the Securities and Exchange Commission (the "SEC") in connection with the Radoff-JEC Group's solicitation of proxies relating to the Company's 2026 annual meeting of stockholders scheduled to take place on July 28, 2026 at 1:30 p.m. Pacific Time by means of remote communication virtually on the Internet and accessible at www.cesonlineservices.com/seer26_vm (including any adjournments, postponements or continuations thereof and any meeting which may be called in lieu thereof, the "Annual Meeting"), where stockholders will have an opportunity:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. To elect the Radoff-JEC Group's three (3) director nominees, Howard H. Berman, Ph.D., Joshua S.
Horowitz and Luis E. Rinaldini (collectively, the "Radoff-JEC Nominees"), each to serve until the 2027 annual meeting of stockholders
(the "2027 Annual Meeting") and until such director's successor is elected and qualified or until such director's
earlier death, resignation or removal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. To ratify the appointment of Deloitte & Touche LLP ("Deloitte") as the Company's
independent registered public accounting firm for the Company's fiscal year ending December 31, 2026;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. To conduct a non-binding advisory vote to approve named executive officer compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. To ratify the Tax Benefit Preservation Plan (the "NOL Pill") so that it may remain in effect
through February 25, 2029, unless earlier terminated by the Board; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. To transact such other business as may properly come before the Annual Meeting.

These items of business are more fully described in the Proxy Statement filed with the SEC on June 1, 2026.

This proxy statement supplement (this "Proxy Supplement") supplements the Proxy Statement to include certain information disclosed in the Company's definitive proxy statement filed with the SEC on June 3, 2026, which was not publicly available at the time we filed the Proxy Statement.

According to the Company's definitive proxy statement, the Annual Meeting will take place on July 28, 2026 at 1:30 p.m. Pacific Time and will be held by means of remote communication virtually on the Internet and will be accessible at www.cesonlineservices.com/seer26_vm. For further information on how to attend and vote virtually at the Annual Meeting, please see the "Virtual Meeting" section of this Proxy Supplement.

According to the Company's definitive proxy statement, the Company has set the close of business on May 29, 2026 as the record date for determining stockholders entitled to notice of and to vote at the Annual Meeting (the "Record Date"). Only stockholders of record as of the close of business on the Record Date are entitled to notice of and to vote at the Annual Meeting. According to the Company's definitive proxy statement, as of the Record Date, there were 55,315,982 shares of Common Stock outstanding.

**OTHER SUPPLEMENTAL DISCLOSURES**

***Virtual Meeting***

According to the Company's definitive proxy statement, the Annual Meeting will be held by means of remote communication virtually on the Internet and stockholders will not be able to attend the Annual Meeting at a physical location. According to the Company's definitive proxy statement, to participate in the Annual Meeting, stockholders should visit: www.cesonlineservices.com/seer26_vm. Stockholders may begin to log into the meeting platform beginning at 1:00 p.m., Pacific Time, on Tuesday, July 28, 2026. The webcast will begin promptly at 1:30 p.m., Pacific Time. According to the Company's definitive proxy statement, to attend and vote at the Annual Meeting, stockholders must have pre-registered using the instructions provided below.

According to the Company's definitive proxy statement, if stockholders encounter any technical difficulties with the virtual meeting website on the day of the Annual Meeting, they should call the technical support number that will be listed in the Company's reminder email sent the night before the Annual Meeting. Technical support will be available starting at 1:00 p.m., Pacific Time, on July 28, 2026, and until the Annual Meeting has finished.

*Stockholders of Record*

If, on the Record Date, your shares were registered directly in your name with Computershare Trust Company, N.A., the Company's transfer agent, then you are considered a "stockholder of record."

According to the Company's definitive proxy statement, in order to attend the Annual Meeting, stockholders of record will **<u>need to pre-register by 1:30 p.m., Pacific Time, on Monday, July 27, 2026</u>**. To pre-register, please visit www.cesonlineservices.com/seer26_vm with the control number from your **WHITE** proxy card. After registering, you will receive a confirmation email with a link and instructions for accessing the Annual Meeting. Please verify that you have received the confirmation email in advance of the Annual Meeting, including the possibility that it may be in your spam or junk email folder. Registration requests must be received no later than 1:30 p.m. Pacific Time, on Monday, July 27, 2026. **You must pre-register and receive a confirmation email in order to vote or submit a question during the Annual Meeting.**

*Beneficial Owner of Shares Held in "Street Name"*

If, on the Record Date, your shares were held not in your name, but rather by a broker, bank or other nominee, then you are the "beneficial owner" of shares held in "street name" and you are considered a "street name stockholder."

According to the Company's definitive proxy statement, in order to attend the Annual Meeting, street name stockholders will **<u>need to pre-register by 1:30 p.m., Pacific Time, on Monday, July 27, 2026</u>**. To pre-register, please visit www.cesonlineservices.com/seer26_vm with the control number from your **WHITE** voting instruction form or other instructions received from your broker, bank or other nominee. After registering, you will receive a confirmation email with a link and instructions for accessing the Annual Meeting. Please verify that you have received the confirmation email in advance of the Annual Meeting, including the possibility that it may be in your spam or junk email folder. Registration requests must be received no later than 1:30 p.m., Pacific Time, on Monday, July 27, 2026.

According to the Company's definitive proxy statement, street name stockholders who intend to vote during the Annual Meeting must obtain and submit a legal proxy from their broker, bank or other nominee. Most of these entities allow a stockholder to obtain a legal proxy either online or by mail. If you request a legal proxy online and do not receive an email containing your legal proxy within two business days of such request, contact your broker, bank or other nominee. If you request a legal proxy by mail and do not receive it within five business days of such request, contact your broker, bank or other nominee.

According to the Company's definitive proxy statement, you may submit your legal proxy either (i) in advance of the Annual Meeting by attaching the legal proxy (or an image thereof in PDF, JPEG, GIF or PNG file format) in an email to SEERRegister@Proxy-Agent.com; or (ii) along with your voting ballot during the Annual Meeting. If you own your shares in street name, the Company must have your legal proxy in order for a vote that you submit during the Annual Meeting to be valid. To avoid any technical difficulties on the day of the Annual Meeting, we encourage you to submit your legal proxy in advance in an email to SEERRegister@Proxy-Agent.com to ensure that your vote is counted, rather than wait to upload your legal proxy during the Annual Meeting. Multiple legal proxies must be combined into one document for purposes of uploading them to the Annual Meeting website.

Whether or not you plan to attend the virtual Annual Meeting, we urge you to sign, date and return the enclosed **WHITE** universal proxy card in the postage-paid envelope provided, or vote via the Internet or by telephone as instructed on the **WHITE** universal proxy card.

***Stockholder Proposals***

According to the Company's definitive proxy statement, for a stockholder proposal to be considered for inclusion in the Company's proxy statement for the 2027 Annual Meeting, the Company's President and Chief Financial Officer must receive the written proposal at the Company's principal executive office not later than February 3, 2027.

According to the Company's definitive proxy statement, the Company's amended and restated bylaws (the "Bylaws") also establish an advance notice procedure for stockholders who wish to present a proposal or nominate directors before an annual meeting of stockholders but do not intend for the proposal to be included in the Company's proxy statement. In order for such a stockholder's notice to be timely under the Bylaws, the Company's President and Chief Financial Officer must receive the written notice at the Company's principal executive office:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• not earlier than 8:00 a.m., Pacific Time, on March 20, 2027; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• not later than 5:00 p.m., Pacific Time, on April 19, 2027.

In the event that the Company holds the 2027 Annual Meeting more than 25 days from the one-year anniversary of the date of the Annual Meeting, then notice of a stockholder proposal or director nomination that is not intended to be included in the Company's proxy statement must be received no earlier than 5:00 p.m., Pacific Time on the 120th day before such annual meeting and no later than 5:00 p.m., Pacific Time on the later of the following two dates:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the 90th day prior to such annual meeting; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the 10th day following the day on which public announcement of the date of such annual meeting is first made.

According to the Company's definitive proxy statement, in addition to satisfying the requirements of the Bylaws, including the earlier notice deadlines set forth above and therein, to comply with universal proxy rules, stockholders who intend to solicit proxies in support of director nominees (other than the Company's nominees) must also provide notice that sets forth the information required by Rule 14a-19 of the Exchange Act, no later than April 19, 2027. However, notwithstanding the foregoing deadline provided in the Company's definitive proxy statement, we believe that the correct deadline under Rule 14a-19 is June 1, 2027 (the first business day after the deadline calculated as 60 calendar days prior to the anniversary of the previous year's annual meeting date).

The information set forth above regarding the procedures for submitting stockholder proposals for consideration at the 2027 Annual Meeting is based on information contained in the Company's proxy statement and the Bylaws. The incorporation of this information in this Proxy Supplement should not be construed as an admission by the Radoff-JEC Group that such procedures are legal, valid or binding.

THE RADOFF-JEC GROUP URGES YOU TO SIGN, DATE AND RETURN THE **WHITE** UNIVERSAL PROXY CARD VOTING "FOR" THE ELECTION OF THE RADOFF-JEC NOMINEES.

**SCHEDULE II**

***The following table is reprinted from the Company's definitive proxy statement filed with the Securities and Exchange Commission on June 3, 2026.***

**SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT**

The following table sets forth certain information with respect to the beneficial ownership of our Class A common stock as of May 11, 2026 for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· each of our directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· each of our named executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· all of our directors and executive officers as a group; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· each person or group known by us to be the beneficial owner of more than 5% of our Class A common stock.

We have determined beneficial ownership in accordance with the rules of the SEC, and thus it represents sole or shared voting or investment power with respect to our securities. Unless otherwise indicated below, to our knowledge, the persons and entities named in the table have sole voting and sole investment power with respect to all shares that they beneficially owned, subject to community property laws where applicable. The information does not necessarily indicate beneficial ownership for any other purpose, including for purposes of Sections 13(d) and 13(g) of the Securities Act.

We have based our calculation of the percentage of beneficial ownership on 54,981,551 shares of our Class A common stock outstanding as of May 11, 2026. We have deemed shares of our Class A common stock subject to stock options that are currently exercisable or exercisable within 60 days of May 11, 2026 to be outstanding and to be beneficially owned by the person holding the stock option for the purpose of computing the percentage ownership of that person. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

Unless otherwise indicated, the address of each beneficial owner listed in the table below is c/o Seer, Inc. 3800 Bridge Parkway, Suite 102, Redwood City, California 94065.
