Rigrodsky & Long, P.A. announces that it is investigating potential claims against the board of directors of Tekelec (“Tekelec” or the “Company”) (Nasdaq: TKLC) concerning possible breaches of fiduciary duty and other violations of law related to the Company’s entry into an agreement to be acquired and taken private by a consortium led by Siris Capital Group, LLC (“Siris”) and including affiliates of The ComVest Group, funds and accounts managed by GSO Capital Partners LP, Sankaty Advisors LLC, ZelnickMedia and other Siris limited partners and affiliates (together, the “Consortium”) in a transaction with an approximate value of $780 million.

Under the proposed agreement, the Consortium will acquire all of the outstanding shares of Tekelec for $11.00 per share in cash. The investigation concerns whether Tekelec’s board of directors adequately shopped the Company to obtain the best price possible for Tekelec’s shareholders before entering into the agreement with the Consortium. Indeed, according to Yahoo! Finance, at least one analyst has set a $16.00 per share price target for Tekelec stock.
