On September 3, it was announced that Japanese pharmaceutical manufacturer Dainippon Sumitomo Pharma Co., Ltd. (DSP) and Willkie client Sepracor Inc., a specialty drug maker, have entered into a definitive agreement pursuant to which DSP will acquire Sepracor for approximately $2.6 billion. The acquisition will be made through a cash tender offer of $23.00 per share, followed by a merger to acquire all remaining outstanding Sepracor shares at the same price paid in the tender offer. Upon completion of the acquisition, Sepracor will become a wholly owned subsidiary of Dainippon Sumitomo Pharma America Holdings, Inc., a wholly owned U.S. subsidiary of DSP. The company will continue to operate as Sepracor with operations based in Marlborough, Massachusetts and in Canada.
