Item 1.01

Entry into a Material Definitive Agreement.

Agreement and Plan of Merger

On October 9, 2025, Akero Therapeutics, Inc. (the “Company” or “Akero”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Novo Nordisk A/S, a Danish aktieselskab (“Parent”), and NN Invest Sub, Inc, a Delaware corporation and a direct or indirect wholly owned subsidiary of Parent (“Merger Sub”), providing for the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Parent. Capitalized terms used herein and not otherwise defined herein have the meanings set forth in the Merger Agreement.

At the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.0001 per share, of the Company (“Company common stock”) issued and outstanding immediately prior to the Effective Time (other than Excluded Shares and Dissenting Shares) will automatically be cancelled and converted into the right to receive (i) cash in an amount equal to $54.00, without interest thereon and subject to any applicable tax withholdings (the “Closing Consideration”) and (ii) one contractual contingent value right (a “CVR”) representing the right to receive $6.00 in cash, without interest and subject to any applicable tax withholdings, if a specified milestone is achieved, pursuant to the CVR Agreement (as defined and further described below).

Consummation of the Merger is subject to customary closing conditions, including, without limitation, the absence of certain legal restraints preventing or otherwise making illegal the consummation of the Merger, no Material Adverse Effect with respect to the Company having occurred since the date of the Merger Agreement that is continuing, the expiration or termination of any waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”) applicable to the Merger, the obtainment of any clearance or approval applicable to the Merger under the antitrust and foreign direct investment laws of other applicable foreign jurisdictions, and the adoption of the Merger Agreement by holders of Company common stock representing at least a majority of the outstanding Company’s common stock.

The parties expect the Merger and the other transactions contemplated by the Merger Agreement to close around year end. The Merger Agreement provides that as promptly as reasonably practicable (and in any event within 10 business days) after the date of the Merger Agreement, the Company will prepare and file a preliminary proxy statement relating to the Company’s meeting of its stockholders for the purpose of voting upon the adoption of the Merger Agreement.

At or prior to the Effective Time of the Merger, Parent, a direct or indirect wholly owned subsidiary of Parent designated in the CVR Agreement and a rights agent will enter into a Contingent Value Rights Agreement, in the form attached as Annex I to the Merger Agreement, with such changes as may be permitted by the Merger Agreement (the “CVR Agreement”).

The Company has made customary representations and warranties in the Merger Agreement and has agreed to customary covenants regarding the operation of the business of the Company and its Subsidiaries prior to the Effective Time. The Company is also subject to customary restrictions on its ability to solicit alternative acquisition proposals from third parties and to provide non-public information to, and participate in discussions and engage in negotiations with, third parties regarding alternative acquisition proposals, with customary exceptions to allow the Board of Directors to exercise its fiduciary duties. These exceptions include that, subject to the terms and conditions of the Merger Agreement, if the Company receives an acquisition proposal that did not result from the Company’s breach of its no-shop covenants, and following such receipt, the Board of Directors determines in good faith, after consultation with its outside legal counsel, that such acquisition proposal is or could lead to a Superior Offer and the failure to terminate the Merger Agreement and change its recommendation of the Merger to the Company’s stockholders would be inconsistent with the Board of Directors’ fiduciary duties under applicable law, then the Company is permitted to terminate the Merger Agreement and the Board of Directors is permitted to change its recommendation of the Merger to the Company’s stockholders (subject to certain customary match rights in favor of Parent).

The Merger Agreement contains certain termination rights for the Company and Parent. Subject to the terms and conditions of the Merger Agreement, the Company or Parent may terminate the Merger Agreement if the Merger is not consummated by 11:59 PM Eastern Time, on April 9, 2026, which period may be extended automatically for six months if at the end of the prior period, all conditions to closing of the Merger other than conditions relating to the HSR Act or other applicable antitrust and foreign direct investment laws have been obtained or waived as of such date, and extended for an additional six-month period if at the end of the prior period, all conditions to closing of the Merger other than conditions relating to the HSR Act or other applicable antitrust and foreign direct investment laws have been obtained or waived as of such date and either Company or Parent (in each of their sole discretion) provides prompt notice of such decision to extend (the “End Date”).

Upon termination of the Merger Agreement, under specified circumstances, the Company will be required to pay Parent a termination fee of $165,000,000. Such circumstances include where the Merger Agreement is terminated (i) in connection with the Company accepting a Superior Offer and entering an agreement for the consummation of a transaction which the Board of Directors determines constitutes a Superior Offer and (ii) due to the Board of Directors’ change of, or failure to reaffirm as required by the Merger Agreement, its recommendation of the Merger to the Company’s stockholders. The termination fee will also be payable if the Merger Agreement is terminated (i) (a) by Parent or the Company because the Merger is not consummated before the End Date (but in the case of a termination by the Company, only if Parent would not be prohibited from terminating the Merger Agreement on this basis because its material breach had caused or resulted in the Merger not being consummated by the End Date), (b) by Parent or the Company due to failure to obtain the requisite Company stockholder vote to adopt the Merger Agreement, or (c) by Parent because the Company breaches its representations, warranties or covenants in a manner that would cause the related closing conditions to not be met (provided that neither Parent nor Merger Sub is then in breach of its representations, warranties or covenants in a manner that would cause the related closing conditions to not be met), (ii) prior to any such termination, a proposal to acquire 50% or more of the Company’s stock or assets is communicated to the Board of Directors or publicly disclosed and has not been withdrawn, and (iii) the Company enters into an agreement for, or consummates, a transaction involving an acquisition of 50% or more of the Company’s stock or assets within 12 months of such termination.

The Merger Agreement further provides that Parent will be required to pay the Company a reverse termination fee of $185,000,000 in the event the Merger Agreement is terminated in certain specified circumstances, including if the Merger is not consummated before the End Date because certain conditions related to antitrust or foreign direct investment laws have not been satisfied.

At the Effective Time, each Company Option that is then outstanding and unexercised, whether or not vested and which has a per share exercise price that is less than the Closing Consideration (each, an “In the Money Option”), will be cancelled and converted into the right to receive a cash payment equal to the product of the excess of the Closing Consideration over the per share exercise price of such In-the-Money Option, multiplied by the total number of shares of Company common stock subject to such In-the-Money Option immediately prior to the Effective Time, plus one CVR for each share of Company common stock subject to such In-the-Money Option immediately prior to the Effective Time.

Holders of Company Options which have a per share exercise price equal to or exceeding the Closing Consideration (each, an “Out of the Money Option”) will be entitled to exercise such Out of the Money Options on a basis that allows such holders to participate in the Merger. Out of the Money Options that remain outstanding and unexercised as of the Effective Time will be cancelled for no consideration.

At the Effective Time, each then outstanding Company RSU will be cancelled and the holder thereof will be entitled to receive a cash payment equal to the product of the Closing Consideration and the number of shares of Company common stock subject to such Company RSU, plus one CVR for each share of Company common stock subject to the Company RSU.

The representations, warranties and covenants of the Company contained in the Merger Agreement have been made solely for the benefit of Parent and Merger Sub. In addition, such representations, warranties and covenants (i) have been made only for purposes of the Merger Agreement and (ii) have been included in the Merger Agreement for the purpose of allocating risk between the contracting parties rather than establishing matters as fact. In addition, the representations, warranties and covenants have been qualified by (a) matters specifically disclosed in certain of the Company’s filings with the United States Securities and Exchange Commission (“SEC”), (b) confidential

disclosures made to Parent and Merger Sub in the disclosure letter delivered in connection with the Merger Agreement and (c) materiality qualifications contained in the Merger Agreement, which may differ from what may be viewed as material by investors. Accordingly, the Merger Agreement is included with this filing only to provide investors with information regarding the terms of the Merger Agreement, and not to provide investors with any other factual information regarding the Company or its business.

Contingent Value Rights Agreement

At or prior to the Effective Time, Parent and a rights agent will enter into the CVR Agreement governing the terms of the CVRs. The CVRs are contractual rights only and are not transferable except under certain limited circumstances, will not be evidenced by a certificate or other instrument and will not be registered with the SEC or listed for trading. The CVRs will not have any voting or dividend rights and will not represent any equity or ownership interest in Parent, any constituent corporation party to the Merger Agreement or any of their respective affiliates or subsidiaries.

Each CVR represents a non-tradeable contractual contingent right to receive $6.00, without interest and subject to applicable tax withholdings (the “Milestone Payment”), upon receipt by Parent or one of its affiliates or assignees, prior to June 30, 2031, of FDA Approval for efruxifermin for subcutaneous injection (whether alone or in combination with another product) for the treatment of patients with compensated cirrhosis (consistent with stage F4c fibrosis) due to metabolic dysfunction-associated steatohepatitis, and which expressly sets forth the foregoing as an indication in the indications and usage section of the FDA-approved prescribing information for such product (the “CVR Milestone”).

There can be no assurance that the CVR Milestone will be achieved by June 30, 2031, or that the Milestone Payment will become payable to holders of CVRs.

Additional Information

The foregoing description of the Merger Agreement and the CVR Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1, and the Form of CVR Agreement, which is attached as Annex I to the Merger Agreement, and the terms of which are incorporated herein by reference.

Investors should not rely on the representations, warranties and covenants or any descriptions thereof as characterizations of the actual state of facts or condition of the Company or any of its subsidiaries or affiliates. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.
