FORT MYERS, Fla., May 21, 2024 – American Oncology Network (“AON” or the “Company”) (Nasdaq: AONC), a rapidly growing network of community-based oncology practices, announced today its decision to voluntarily delist its Class A common stock and warrants from The Nasdaq Capital Market (“Nasdaq”). The Company’s decision to delist its securities from Nasdaq was recommended to the Board of Directors (the “Board”) of the Company by a Special Committee (the “Special Committee”) of the Board comprised solely of independent directors.

The Company intends to file a Form 25 with the Securities and Exchange Commission (the “SEC”) to delist its Class A common stock and warrants from Nasdaq and to deregister its Class A common stock and warrants under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), on or about May 31, 2024, and as a result, the Company expects that the last trading day of its Class A common stock and warrants on Nasdaq will be on or about June 7, 2024.

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 stakeholders. 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 its securities on Nasdaq, and (3) the required personnel resources and expenses 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 attention of the Company’s management team.

Todd Schonherz, Chief Executive Officer, commented, “AON has delivered an impressive five-year revenue CAGR of 42% and continues to experience strong momentum with the addition of 40 providers and four new practices to the network year-to-date. AON is in a healthy financial position with a robust balance sheet of over $100 million in cash and short-term securities as of March 31, 2024. While going public allowed us to raise growth capital and provide equity to key stakeholders, we believe that we will be better positioned to maximize shareholder value going forward by delisting.”

Following the delisting of the Company’s common stock and warrants from Nasdaq, the Company expects that its common stock and warrants will be quoted for trading on a market operated by OTC Markets Group Inc. (the “OTC”) so that a trading market may continue to exist for such securities. There is no guarantee, however, that a broker will continue to make a market in the common stock and warrants.

Sakeer Hussain, MD, of Heartland Oncology & Hematology, was recognized for his involvement at the 2024 Advocacy Summit event.

COUNCIL BLUFFS, Iowa, May 14, 2024 –  Sakeer Hussain, MD, Board-certified medical oncologist at Heartland Oncology & Hematology, a partner practice of the American Oncology Network (AON) (Nasdaq: AONC), one of the nation’s fastest-growing community oncology networks, was named an Advocacy Champion by the Association for Clinical Oncology (ASCO) during the Association’s 2024 Advocacy Summit in April.

Advocacy Champions are ASCO volunteers who have made meaningful contributions to ASCO’s advocacy activities throughout the year to ensure that every patient with cancer has access to high-quality, high-value cancer care, no matter who they are or where they live. Advocates speak with federal lawmakers and agencies, send personalized letters to Members of Congress through ASCO’s ACT Network, engage with state lawmakers on policy priorities at the state level, and host site visits for lawmakers in their home states and districts.

“ASCO’s Advocacy Champions are instrumental in making lasting policy changes that positively impact cancer care and research,” said Piyush Srivastava, MD, FASCO, chair of ASCO’s Government Relations Committee. “They have worked tirelessly this year to advance policy that would end drug shortages, provide robust federal funding for cancer research, and expand telehealth flexibilities permanently. Their efforts will affect cancer care providers, researchers, and patients for years to come.”

Throughout the past year, Dr. Hussain has participated in a variety of advocacy activities, including annual visits to Washington, D.C. to meet with Congress representatives and speak on patient care challenges and opportunities such as prior authorization and telemedicine expansion flexibilities. Additionally, he gave testimony in the Iowa House of Representatives against medical switching and has hosted the local congressman at the clinic.

“Being named an ASCO Advocacy Champion is an honor and incredibly humbling, and it is a privilege to contribute to such a worthy cause as ASCO’s advocacy initiatives,” said Dr. Hussain. “Receiving this recognition means a lot to me and is a testament to my ongoing commitment to closing the cancer care gap and removing barriers to accessible cancer care and services. I look forward to continuing to fight for a system where everyone has access to the cancer care they need, regardless of their background or circumstances.”

“We are proud to learn that Dr. Hussain has been named an ASCO Advocacy Champion, and it is a well-deserved recognition of his passion and commitment to patient care and community oncology,” said Stephen “Fred” Divers, MD, AON’s chief medical officer. “Dr. Hussain’s work with ASCO bridges the critical gap between community oncology practices and federal lawmakers and aligns with our company mission to ensure the viability of independent oncology practices. His involvement directly impacts health policy decisions and calls attention to the importance of having local cancer care options available. It is an honor to have Dr. Hussain in our network, and we are excited to witness what he accomplishes next through this platform.”
