Annovis Bio, Inc. (NYSE: ANVS) filed an 8-K on June 19, 2025 to disclose that the New York Stock Exchange has accepted the company’s previously submitted listing-compliance plan. The plan was required after Annovis fell out of compliance with NYSE continued-listing standards; acceptance removes the immediate risk of delisting and starts a defined remediation timetable. The 8-K furnishes, but does not file, a press release (Exhibit 99.1) announcing the NYSE decision. No financial statements, earnings data or major transactions were included, and the disclosure is made solely under Item 7.01 (Regulation FD) with no impact on historical financial reporting.
Investors should note that, while acceptance is a constructive step, Annovis must still meet the milestones outlined in the compliance plan to regain full compliance. The filing contains no new operational or financial metrics.
