Explanation of Responses:

( 1 )On September 20, 2023, the reporting persons filed a Form 4 which erroneously reported that the reporting persons held 8,112,500 shares of Class A common stock of American Oncology Network, Inc. ("New AON"). In fact, as reported in this amendment, the reporting persons held 5,273,125 shares of Class A common stock of New AON, which excludes 2,839,375 Class A common shares of New AON that are subject to earnout pursuant to the Amended and Restated Sponsor Support Agreement, dated as of January 6, 2023, by and among Digital Transformation Opportunities Corp., Digital Transformation Sponsor LLC (the "Sponsor"), New AON and the other persons party thereto. ( 2 )Mr. Kevin Nazemi is the sole manager of the Sponsor. As such, Mr. Nazemi has sole voting and dispositive power with respect to the Class A common shares of New AON owned by the Sponsor and thus is the beneficial owner of such shares.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
