Rigrodsky & Long, P.A. Announces Investigation Of KYTHERA Biopharmaceuticals, Inc. (NASDAQ GS: KYTH) Buyout

Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of KYTHERA Biopharmaceuticals, Inc. (“KYTHERA” or the “Company”) (NASDAQ GS: KYTH) regarding possible breaches of fiduciary duties and other violations of law related to the Company’s entry into an agreement to be acquired by Allergan plc (“Allergan”) (NYSE: AGN), in a transaction valued at approximately $2.1 billion.

Under the terms of the agreement, shareholders of KYTHERA will receive $75.00 in cash and Allergan shares for each share of KYTHERA they own.

The investigation concerns whether KYTHERA’s board of directors failed to adequately shop the Company and obtain the best possible value for KYTHERA’s shareholders before entering into an agreement with Allergan.  According to Yahoo! Finance, at least one analyst has issued a price target for KYTHERA stock at $85.00 per share.
