Item 1.01 Entry into a Material Definitive Agreement.

The Asset Purchase Agreement

On December 22, 2023, (the “Execution Date”) Atreca, Inc., a Delaware corporation (the “Company”), and Immunome, Inc. (“Purchaser”), entered into an Asset Purchase Agreement (the “Asset Purchase Agreement”) pursuant to which Purchaser will acquire certain of the Company’s preclinical monoclonal-antibody (mAb) assets in oncology (the “Asset Sale”), which will constitute substantially all of the Company’s assets. Immunome is not purchasing any platform-related assets of Atreca. Pursuant to the Asset Purchase Agreement, Purchaser will pay to the Company an aggregate purchase price of up to $12,500,000 in cash, with $5,500,000 due to the Company at the closing of the Asset Sale (the “Closing”) and up to $7,000,000 due upon the achievement of certain clinical-based milestone events set forth in, subject to the terms and conditions of, a Contingent Value Rights Agreement substantially in the form attached as Exhibit D to the Asset Purchase Agreement (the “CVR Agreement”).

The Asset Purchase Agreement, the Asset Sale and the other transactions contemplated by the Asset Purchase Agreement have been unanimously approved by the board of directors of the Company (the “Board”). The Asset Purchase Agreement, the Asset Sale and other transactions contemplated by the Asset Purchase Agreement must also be approved by the Company’s stockholders, as a condition to the closing.

The Asset Purchase Agreement contains customary representations, warranties, conditions and covenants, including covenants (i) concerning the conduct of business by the Company prior to the Closing and (ii) prohibiting the Company and its representatives from soliciting, initiating or knowingly inducing, encouraging or facilitating any competing acquisition proposal, subject to certain limited exceptions. In addition, the Company and Purchaser have agreed to use their best efforts to consummate the Asset Sale and other transactions contemplated by the Asset Purchase Agreement.

The Company will prepare and file a proxy statement with the U.S. Securities and Exchange Commission (the “SEC”) and, subject to certain exceptions, the Board will recommend that the Asset Purchase Agreement be adopted by the Company’s stockholders at a special meeting of the Company’s stockholders (the “Board Recommendation”). However, subject to the satisfaction of certain terms and conditions, the Company and the Board, as applicable, are permitted to take certain actions which may, as more fully described in the Asset Purchase Agreement, include changing the Board Recommendation as a result of an intervening event if, and among other things, the Board has concluded in good faith after consultation with its financial advisors and outside legal counsel that the failure to take such action would reasonably be expected to be inconsistent with the Board’s fiduciary duties to the Company’s stockholders under applicable law.

Each party’s obligation to consummate the Asset Sale is also conditioned upon certain other customary closing conditions, including the accuracy of the other party’s representations and warranties as of the Closing, subject, in certain instances, to certain materiality and other thresholds, the performance by the other party of its obligations and covenants under the Asset Purchase Agreement in all material respects, obtaining the requisite stockholder vote, the delivery of certain related ancillary documents by the other party and the absence of any injunction or other legal prohibitions preventing consummation of the Asset Sale. The Company has also agreed to indemnify Purchaser from and against any losses due to breaches of the Company’s representations, warranties and covenants contained in the Asset Purchase Agreement and certain other liabilities, with Purchaser’s recovery for such losses to be limited to its right of set-off against any Milestone Payments subsequently payable to the Company and subject to certain specified limitations.

The Asset Purchase Agreement contains certain customary termination rights in favor of each of the Company and Purchaser, including Purchaser’s right to terminate the Asset Purchase Agreement if the Board changes the Board Recommendation. In addition, subject to customary exceptions, the Asset Purchase Agreement may be terminated by either party if the Closing has not occurred by the six-month anniversary of the Execution Date, subject to extension in certain specified circumstances. In connection with a termination of the Asset Purchase Agreement by Purchaser under specified circumstances, including due to a change in the Board Recommendation or the failure of the Company’s stockholders to approve the Asset Purchase Agreement, the Company will be required to reimburse Purchaser for its reasonable, documented out-of-pocket fees and expenses, up to a maximum of $500,000, incurred in connection with the transactions contemplated by the Asset Purchase Agreement.

The Asset Purchase Agreement has been included as an exhibit hereto solely to provide investors with information regarding its terms. It is not intended to be a source of financial, business or operational information about the Company. The representations, warranties and covenants contained in the Asset Purchase Agreement were made only for the purposes of the Asset Purchase Agreement as of the dates specified therein and solely for the benefit of the parties to the Asset Purchase Agreement. In addition, the representations, warranties and covenants contained in the Asset Purchase Agreement may be subject to qualifications and limitations agreed upon by the parties in connection with negotiating the terms of the Asset Purchase Agreement, including the Company’s representations, warranties and covenants being qualified by confidential disclosure schedules made for the purpose of allocating contractual risk amongst the parties as opposed to establishing such matters as facts, and may further be subject to certain standards of materiality applicable to the parties that differ from those applicable to investors. As a result, investors should not rely on the representations, warranties and covenants included in the Asset Purchase Agreement, or any descriptions thereof, as characterizations of the actual state of facts or condition of the Company and its business. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Asset Purchase Agreement, which subsequent information may or may not be fully reflected in public disclosures.

The foregoing description of the terms of the Asset Purchase Agreement is not complete and is qualified in its entirety by reference to the Asset Purchase Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.

Support Agreement

In connection with the execution of the Asset Purchase Agreement, the Company and Purchaser entered into a stockholder support agreement (the “Support Agreement”) with the Company’s officers, directors and certain stockholders holding approximately 7.94% of the outstanding shares of the Company’s common stock. The Support Agreement provides that, among other things, each of the parties thereto has agreed to vote or cause to be voted all of the shares of the Company’s capital stock owned by such stockholder in favor of adopting and approving the Asset Purchase Agreement, and approving the Asset Sale, the Dissolution (as defined below) and other transactions contemplated by the Asset Purchase Agreement and any and all other agreements entered into in connection with the Asset Sale at the Company stockholders’ meeting to be held in connection therewith and against any proposal made in opposition to, or in competition with, or would otherwise be reasonably be expected to impede, interfere with, delay, postpone, discourage or adversely affect the Asset Sale, Asset Sale, the Dissolution (as defined below) and other transactions contemplated by the Asset Purchase Agreement and any and all other agreements entered into in connection with the Asset Sale.

The foregoing description of the Support Agreement does not purport to be complete and is qualified in its entirety by reference to the form of Support Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.

Contingent Value Rights Agreement

The Asset Purchase Agreement contemplates that prior to the Closing, the Company and a duly qualified rights agent reasonably agreeable to the Company to enter into the CVR Agreement, pursuant to which each stockholder of the Company as of the applicable record date shall be entitled to one contractual contingent value right issued by the Company, subject to and in accordance with the terms and conditions of the CVR Agreement, for each share of common stock held by such holder. The contingent value rights shall entitle the holders thereof to receive up to $7,000,000 in cash in the aggregate upon the achievement of certain clinical-based milestone events set forth in, and subject to and in accordance with the terms and conditions of, the CVR Agreement. The contingent value rights are not transferable, except in certain limited circumstances as will be provided in the CVR Agreement, will not be certificated or evidenced by any instrument and will not be registered with the SEC or listed for trading on any exchange.

The foregoing description of the CVR Agreement does not purport to be complete and is qualified in its entirety by reference to the form of the CVR Agreement, which is attached as Exhibit D to the Asset Purchase Agreement, a copy of which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference.
