Phio Pharmaceuticals Announces Reverse Stock Split

Phio Pharmaceuticals Corp. (Nasdaq: PHIO), a clinical stage biotechnology company whose proprietary INTASYL RNAi platform technology is designed to make immune cells more effective in killing tumor cells, today announced that the Company’s Board of Directors has approved a reverse stock split of its shares of common stock at a ratio of 1-for-12. The reverse stock split will become effective at 12:01 a.m. Eastern Time on January 26, 2023 and the Company’s common stock will open for trading on The Nasdaq Capital Market on a post-split basis on January 26, 2023 under the Company’s existing trading symbol, “PHIO.” At such time, the Company’s common stock will also commence trading with a new CUSIP number, 71880W402.

The reverse stock split is being implemented to increase the per share trading price of the Company’s common stock, for the purpose of ensuring a share price high enough to comply with the minimum $1.00 bid price requirement for continued listing on The Nasdaq Capital Market.

At the effective time of the reverse stock split, every twelve (12) shares of Phio common stock issued and outstanding will be combined into one (1) share of common stock issued and outstanding, with no change to the par value of $0.0001 per share. This will reduce the Company’s outstanding common stock from approximately 13.7 million shares to approximately 1.1 million shares. No fractional shares of common stock will be issued as a result of the reverse stock split and instead holders of Phio common stock will receive a cash payment in lieu of fractional shares to which they would otherwise be entitled. The shares underlying the Company’s outstanding equity awards and warrants will also be adjusted accordingly. The reverse stock split affects all stockholders uniformly and will not alter any stockholder’s percentage interest in the Company’s common stock, except for adjustments that may result from the treatment of fractional shares.

The Company has retained its transfer agent, Computershare Trust Company, N.A. (“Computershare”), to act as its exchange agent for the reverse split. Shareholders with shares held in certificate form will receive from Computershare instructions regarding the exchange of their certificates. Shareholders that hold shares in book-entry form or hold their shares in brokerage accounts are not required to take any action and will see the impact of the reverse stock split reflected in their accounts, subject to brokers’ particular processes. Beneficial holders of Phio common stock are encouraged to contact their bank, broker, custodian or other nominee with questions regarding procedures for processing the reverse stock split.

Additional information regarding the reverse stock split is available in the definitive proxy statement filed with the U.S. Securities and Exchange Commission on November 30, 2022 by the Company.
