Foti, Jr., Esq. and the law firm of Kahn Swick & Foti, LLC ("KSF") are investigating the proposed sale of Avadel Pharmaceuticals plc (NasdaqGM: AVDL) to Alkermes plc (NasdaqGS: ALKS). Under the terms of the proposed transaction, shareholders of Avadel will receive $18.50 per share, plus a non-transferable contingent value right entitling holders to a potential additional cash payment of $1.50 per share, contingent upon final FDA approval of LUMRYZ™ for the treatment of idiopathic hypersomnia in adults by the end of 2028. KSF is seeking to determine whether this consideration and the process that led to it are adequate, or whether the consideration undervalues the Company.
