Item 1.01 Entry Into a Material Definitive Agreement.

On July 19, 2024, American Oncology Network, Inc. (the “Company”) and AEA Growth Management LP (“AEA”) entered into a Stockholders Agreement that provides for certain customary shareholder protection in the event that AEA and their affiliated entities (the “AEA Parties”) collectively and beneficially own at least 40% of outstanding voting power of the Company (the “Stockholders Agreement Effectiveness Date”).

The shareholder protections include the following:

Independent Board Members and Corporate Governance: Designation of two directors (the “Independent Directors”) for whom the AEA Parties have agreed to vote in director elections for election to the Company’s board of directors (the “Board”), including (i) at least one independent director by mutual agreement of the other then-sitting independent directors and (ii) one minority independent director (the “Minority Independent Director”), and maintenance of the Nominating and Governance Committee of the Board, which shall be comprised of at least two independent directors.

Co-sale right: In the event the AEA Parties propose to sell more than 10% of the Company’s outstanding equity securities, the other shareholders of the Company have the right to participate in such sale, subject to certain exceptions (such sale a “Co-Sale Transaction”).

Minority Independent Director Consent: For two years following the Stockholders Agreement Effectiveness Date, without the consent of the Minority Independent Director, the Company shall not (i) amend its charter, bylaws or organization documents of any of the Company’s subsidiaries that would adversely affect the rights of the minority stockholders in a disproportionate manner, nor (ii) enter into any transaction with the AEA Parties, other than (x) a Co-Sale Transaction, (y) any transaction expressly permitted under the Stockholders Agreement, and (z) standard employee benefits and director and officer indemnification agreements.

AEA Parties Standstill: The AEA Parties agree to refrain from taking any action that would directly or indirectly cause its ownership of the Company to exceed 80% of the Company’s outstanding voting power, without the consent in writing of the Minority Independent Director.

The Stockholder Agreement terminates upon the earliest of (i) the consummation of a short-form merger pursuant to Section 253 of the Delaware General Corporation Law, (ii) the date that the AEA Parties cease to beneficially own, directly or indirectly, at least 25% of the outstanding voting securities of the Company, (iii) the time at which none of the Company’s securities are owned by any person or entity other than the AEA Parties, and (iv) June 10, 2027, if the Stockholders Agreement Effectiveness Date has not occurred by then.
