Former Attorney General of Louisiana Charles C. Foti, Jr., Esq. and the law firm of Kahn Swick & Foti, LLC (“KSF”) are investigating the proposed sale of OptiNose, Inc. (NasdaqGS: OPTN) to Paratek Pharmaceuticals. Under the terms of the proposed transaction, shareholders of OptiNose will receive $9.00 per share in cash, plus up to $5.00 per share in contingent value rights payable in the event that certain net revenue milestones are achieved by XHANCE. KSF is seeking to determine whether this consideration and the process that led to it are adequate, or whether the consideration undervalues the Company.

If you believe that this transaction undervalues the Company and/or if you would like to discuss your legal rights regarding the proposed sale, you may, without obligation or cost to you, e-mail or call KSF Managing Partner Lewis S. Kahn (lewis.kahn@ksfcounsel.com) toll free at any time at 855-768-1857, or visit https://www.ksfcounsel.com/cases/nasdaqgs-optn/ to learn more.
