On March 19, 2025, OptiNose, Inc., a Delaware corporation (the “Company”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Paratek Pharmaceuticals, Inc., a Delaware corporation (“Paratek”) and Orca Merger Sub, Inc., a Delaware corporation and wholly owned subsidiary of Paratek (“Merger Sub”). Upon the terms and subject to the conditions set forth in the Merger Agreement, which has been unanimously adopted by the Board of Directors of the Company (the “Board”), Merger Sub will merge with and into the Company, with the Company continuing as the surviving corporation and a wholly owned subsidiary of Paratek (the “Merger”).

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of Company common stock issued and outstanding immediately prior to the Effective Time, other than shares owned by the Company (including held in the Company’s treasury), Paratek, Merger Sub or any other wholly owned subsidiary of Paratek or the Company (which will be cancelled) and shares with respect to which appraisal rights are properly exercised and perfected and not effectively withdrawn under Delaware law, will automatically be converted into the right to receive (i) $9.00 in cash, without interest and (ii) one contractual contingent value right representing the right to receive two contingent cash payments with an aggregate maximum amount payable of $5.00, subject to the achievement of certain net sales-based milestones pursuant to the terms of the Contingent Value Rights Agreement, to be entered into at or immediately prior to the Effective Time, between Paratek and a rights agent. The material terms of the Merger Agreement, including the conditions of the proposed Merger will be described in a subsequent filing on Form 8-K.

A copy of the press release jointly issued by the Company and Paratek is furnished as Exhibit 99.1 hereto and is incorporated herein by reference.
