Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On May 21, 2024, American Oncology Network, Inc. (the “Company”) announced that it has determined to voluntarily delist its Class A Common Stock (“Common Stock”) and publicly traded warrants to purchase Class A Common Stock (the “Warrants”) from the Nasdaq Capital Market (“Nasdaq”), as recommended to the Board of Directors (the “Board”) of the Company by a special committee (the “Special Committee”) of the Board comprised solely of disinterested directors. On May 21, 2024, the Company notified Nasdaq of its determination.

In making its determination, the Special Committee concluded that delisting the Company’s securities from Nasdaq is in the best interests of the Company and its stockholders. The Special Committee’s recommendation and the Board’s decision were the product of careful review and consideration of a number of factors, including, but not limited to, (1) the lack of research coverage of the Company by securities and industry analysts, (2) the lack of an active trading market for our securities on Nasdaq, and (3) the required personnel resources and the high costs relating to continued Exchange Act and Nasdaq disclosure and reporting requirements and related regulatory burdens, which have resulted and would continue to result in significant operating expense and significant attention of the Company’s management team. In addition, the Company and certain of its significant equityholders also agreed to certain protections for the holders of the Company’s common equity following the delisting, including (1) in the event such significant equityholders arrange for purchases or other acquisitions of the Company’s outstanding equity securities, such acquisitions would be made at a premium to the trading price of the Company’s Class A common stock prior to delisting, which premium shall not be less than a specified threshold (unless otherwise approved by the Special Committee) and (2) for such equityholders to enter into a customary stockholders’ agreement with the Company under certain circumstances. The Company provides no assurances as to the timing, pricing, or occurrence of any purchases or other acquisitions of the Company’s outstanding equity securities in the future.
A copy of the press release is filed with this Current Report on Form 8-K as Exhibit 99.1 and is incorporated herein by reference.
