Rigrodsky & Long, P.A. Announces Investigation Of Crestwood Midstream Partners LP (NYSE: CMLP) Merger

Rigrodsky & Long, P.A. announces that it is investigating potential legal claims against the board of directors of Crestwood Midstream Partners LP (“Crestwood Midstream” or the “Company”) (NYSE: CMLP) regarding possible breaches of fiduciary duties and other violations of law related to the Company’s entry into an agreement to merge with Crestwood Equity Partners LP (“Crestwood Equity”) (NYSE: CEQP).

Under the terms of the agreement, Crestwood Midstream unitholders will receive 2.75 units of Crestwood Equity for each unit of Crestwood Midstream they own.  Based on Crestwood Equity’s closing price on May 5, 2015, Crestwood Midstream shareholders would have received compensation valued at approximately $18.76 per unit.

The investigation concerns whether Crestwood Midstream’s board of directors failed to adequately shop the Company and obtain the best possible value for Crestwood Midstream’s shareholders before entering into an agreement with Crestwood Equity.  According to Yahoo! Finance, at least one analyst has issued a price target for Crestwood Midstream stock at $26.00 per unit.
