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 Vigil Neuroscience, Inc. (NasdaqGS: VIGL) to Sanofi (NasdaqGS: SNY). Under the terms of the proposed transaction, shareholders of Vigil will receive $8.00 in cash for each share of Vigil that they own as well as a non-tradeable contingent value right entitling the holder to potentially receive an additional $2.00 per share in cash (payable following the first commercial sale of VG-3927 if achieved within a specific period). 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-vigl/ to learn more.
