OptiNose (OPTN) Announces 1:15 Reverse Share Split

Optinose, Inc. (NASDAQ: OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced that it will effect a 1-for-15 reverse stock split at 5:00 p.m. Eastern Standard Time, on December 30, 2024. Beginning with the opening of trading on December 31, 2024, Optinose’s common stock will trade on the Nasdaq Global Select Market (“Nasdaq”) on a split-adjusted basis under a new CUSIP number 68404V209 and Optinose’s existing trading symbol “OPTN.”

The reverse stock split is intended to enable Optinose to regain compliance with the $1.00 minimum closing bid price required for continued listing on Nasdaq.

At a special meeting of stockholders held on December 23, 2024, Optinose’s stockholders approved the proposal to authorize Optinose’s Board of Directors (the “Board”) to file an amendment to Optinose’s fourth amended and restated certificate of incorporation (the “Certificate of Incorporation”) to effect a reverse stock split within a range of 1-for-10 to a maximum of 1-for-100. The specific 1-for-15 ratio was subsequently approved by the Board and the reverse stock split will be effected by filing a Certificate of Amendment to the Certificate of Incorporation with the Secretary of State of the State of Delaware. No further action is required by any stockholders in connection with approving or effecting the reverse stock split.

The reverse stock split will affect all issued and outstanding shares of Optinose’s common stock. At the effective time of the reverse stock split, the number of shares of common stock issued and outstanding will be reduced from 150,829,507 shares to approximately 10,055,300 shares. All outstanding options and warrants entitling their holders to purchase shares of Optinose’s common stock will be adjusted as a result of the reverse stock split, as required by the terms of each security. The number of shares reserved for future issuance pursuant to Optinose’s 2010 Stock Incentive Plan and the number of shares reserved for future issuance pursuant to Optinose’s 2017 Employee Stock Purchase Plan also will be appropriately adjusted. The reverse stock split will affect all stockholders uniformly and will not affect any stockholder's ownership percentage of Optinose’s shares (except to the extent that the reverse stock split would result in some of the stockholders receiving cash in lieu of fractional shares). Stockholders will receive cash in lieu of fractional shares based on the closing price per share of Optinose’s common stock as quoted on Nasdaq on December 30, 2024. The reverse stock split will not reduce the number of authorized shares of common stock or preferred stock or change the par values of Optinose’s common stock (which will remain at $0.001 per share) or preferred stock (which will remain at $0.001 per share).

Broadridge Corporate Issuer Solutions, Inc. (“Broadridge”) is acting as the exchange agent and transfer agent for the reverse stock split. Broadridge will provide instructions to stockholders with physical certificates regarding the process for exchanging their pre-split stock certificates for post-split shares in book-entry form and receiving payment for any fractional shares.

Additional information about the reverse stock split can be found in Optinose’s Definitive Proxy Statement filed with the Securities and Exchange Commission (“SEC”) on December 12, 2024. The Proxy Statement is available at www.sec.gov or at Optinose’s website at www.optinose.com.
