INTRODUCTION

This Amendment No. 1 to the Transaction Statement on Schedule 13E-3 (this "Amended Transaction Statement") is being filed with the U.S. Securities and Exchange Commission (the "SEC") pursuant to Section 13(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), jointly by the following persons (each, a "Filing Person," and collectively, the "Filing Persons"): (1) Fathom Digital Manufacturing Corporation, a Delaware corporation ("Fathom" or the "Company") and the issuer of the common stock, par value $0.0001 per share (the "Class A Common Stock") that is the subject of the Rule 13e-3 transaction; (2) Fathom Holdco, LLC, a Delaware limited liability company ("OpCo LLC"); (3) Fathom Digital Manufacturing Topco, LLC, a Delaware limited liability company ("Topco"); (4) Fathom Digital Manufacturing Intermediate, LLC, a Delaware limited liability company ("Parent"); (5) Fathom Digital Manufacturing Merger Sub, Inc., a Delaware corporation ("Company Merger Sub"); (6) Fathom Digital Manufacturing Merger Sub 2, LLC, a Delaware limited liability company ("LLC Merger Sub"); (7) CORE Industrial Partners Fund I, L.P., a Delaware limited partnership ("CORE Fund I"); (8) CORE Industrial Partners Fund I Parallel, L.P., a Delaware limited partnership ("CORE Fund I Parallel"); (9) CORE Industrial Partners GP I, LLC, a Delaware limited liability company ("CORE Fund I GP"), the general partner of each of CORE Fund I and CORE Fund I Parallel; (10) CORE Industrial Partners Fund III, L.P., a Delaware limited partnership ("CORE Fund III"); (11) CORE Industrial Partners Fund III Parallel, L.P. ("CORE Fund III Parallel"); (12) CORE Industrial Partners GP III, L.P., a Delaware limited partnership ("CORE Fund III GP") and the general partner of each of CORE Fund III and CORE Fund III Parallel; (13) CORE Industrial Partners, LLC, a Delaware limited liability company ("CORE"); and (14) John R. May.

This Amended Transaction Statement relates to that certain Agreement and Plan of Merger, dated as of February 16, 2024 (including all exhibits and documents attached thereto, and as it may be amended, supplemented or modified, from time to time in accordance with its terms, the "Merger Agreement"), by and among Parent, Company Merger Sub, LLC Merger Sub, the Company and OpCo LLC. The Merger Agreement provides that, subject to the terms and conditions set forth therein, Company Merger Sub will merge with and into Fathom (the "Merger"), with Fathom surviving the Merger and becoming a wholly owned subsidiary of Parent.

At the effective time of the Merger (the "Effective Time"), each share of Class A Common Stock issued and outstanding immediately prior to the Effective Time, other than certain excluded shares pursuant to the terms of the Merger Agreement, shall be cancelled and extinguished and automatically converted into and shall thereafter represent only the right to receive an amount in cash equal to $4.75 per share of Class A Common Stock (the "Merger Consideration"), payable to the holder thereof, without interest, subject to and in accordance with the terms of the Merger Agreement. Upon completion of the Merger, the Unaffiliated Stockholders will no longer have an equity interest in Fathom and the Class A Common Stock will no longer be publicly traded.

In connection with entering into the Merger Agreement, on February 16, 2024, Fathom entered into a support agreement with Parent, CORE Fund I and CORE Fund I Parallel (the "Support Agreement"). Pursuant to the Support Agreement, CORE Fund I and CORE Fund I Parallel, among other things, agreed to vote all of their shares of Company Class A Common Stock and Company Class B Common Stock in favor of the adoption of the Merger Agreement and the approval of the Merger, subject to the terms and conditions set forth therein.

The Fathom Board of Directors (the "FathomBoard") formed a special committee of the Board comprised solely of independent and disinterested directors of Fathom (the "Special Committee") to, among other things, review, evaluate and negotiate the Merger Agreement and the Merger, and other alternatives available to Fathom. The Special Committee, as more fully described in the preliminary Proxy Statement, evaluated the Merger, with the assistance of its own independent financial and legal advisors. After careful consideration, the Special Committee, pursuant to resolutions adopted at a meeting of the Special Committee held on February 15, 2024, unanimously (1) determined the terms and conditions of the Merger Agreement and the Transactions, including the Merger, to be advisable and fair to, and in the best interest of, the Company and the Company's stockholders, including the Unaffiliated Stockholders, and (2) recommended that the Fathom Board approve the Merger Agreement and the Transactions, including the Merger, and submit and recommend the Merger Agreement to the Company's stockholders for approval and adoption thereby.

1

The Fathom Board, acting upon the unanimous recommendation of the Special Committee, pursuant to resolutions adopted at a meeting of the Fathom Board held on February 15, 2024, (1) determined the terms and conditions of the Merger Agreement and the Transactions, including the Merger, to be advisable and fair to, and in the best interests of, the Company and the Company's stockholders, including the Unaffiliated Stockholders, (2) approved and declared advisable the Merger Agreement and the Transactions, including the Merger, (3) resolved to recommend that the stockholders of the Company vote to adopt and approve the Merger Agreement in accordance with the DGCL and (4) directed that the Merger Agreement be submitted to the stockholders of the Company for adoption thereby.

The Merger cannot be completed without the affirmative vote of the holders of a majority of the outstanding shares of Company Common Stock to adopt the Merger Agreement. Subject to the terms and conditions contained in the Support Agreement, the required vote by CORE Fund I and CORE Fund I Parallel is expected to result in a majority of the outstanding shares of Company Common Stock being voted in favor of the proposal to approve and adopt the Merger Agreement, with the result being that such proposal will be adopted.

Concurrently with the filing of this Amended Transaction Statement, the Company is filing Amendment No. 1 to its proxy statement (the "Proxy Statement") under Regulation 14A of the Exchange Act with the SEC, pursuant to which the Company is soliciting proxies from the Company's stockholders in connection with the Merger. The Proxy Statement is attached hereto as Exhibit (a)(1). A copy of the Merger Agreement is attached to the Proxy Statement as Annex A. As of the date hereof, the Proxy Statement is in preliminary form, and is subject to completion or amendment. Terms used but not defined in this Amended Transaction Statement have the meanings assigned to them in the Proxy Statement.
