Ampio Pharmaceuticals Announces NYSE American Has Commenced Delisting Proceedings

ENGLEWOOD, Colo., October 4, 2022 — Ampio Pharmaceuticals, Inc. (NYSE American: AMPE) (the “Company”) received written notification from NYSE American LLC (“NYSE American” or the “Exchange”) stating that the staff of NYSE Regulation has determined to commence proceedings to delist the Company’s common stock from the Exchange. Trading in the Company’s common stock was suspended.

NYSE Regulation staff determined that the Company is no longer suitable for listing pursuant to Section 1033(f)(v) of the NYSE American Company Guide due to the abnormally low trading price of the Company’s common stock. The Exchange’s application to the Securities and Exchange Commission to delist the Company’s common stock is pending, subject to the completion of the Exchange’s applicable procedures, including any appeal by the Company of NYSE Regulation’s decision.

The Company has a right to an appeal of this determination by the Exchange, provided that the Company files a written request for such review within seven calendar days after receiving the notice. The Company’s Board of Directors is currently considering whether to appeal the Exchange’s determination to commence delisting proceedings.

Prior to receipt of the letter from NYSE American, the Company began actively taking steps to regain compliance with the listing standards of the NYSE American. Specifically, the Company’s Board of Directors unanimously approved and recommended that the Company’s stockholders approve an amendment to the Company’s certificate of incorporation to effect a reverse stock split of the Company’s common stock at a ratio of not less than 5-to-1 and not greater than

15-to-1, with the exact ratio to be determined by the Board in its discretion before October 13, 2023 (the “Reverse Stock Split”). The Company has called a Special Meeting of Stockholders for October 13, 2022 to consider the Reverse Stock Split. Consummation of the Reverse Stock Split may increase the price of the Company’s shares of common stock and, as a result, would likely enable the Company to maintain a higher market price for its common stock, although there can be no assurance that the Company’s stockholders will approve the Reverse Stock Split. There can be no assurance that the Company will appeal the Exchange’s determination or the outcome of any such appeal. There can be no assurance that the Exchange will reconsider their decision to delist in light of such appeal.

In the meantime, the Company’s common stock will trade on the OTC Pink under the symbol “AMPE.” The Company can provide no assurance that its common stock will continue to trade on this market, that brokers will continue to provide public quotes of the Company’s common stock on this market or otherwise make a market in the Company’s common stock or that the trading volume of the Company’s common stock will be sufficient to provide for an efficient trading market.
