Investigation by Faruqi & Faruqi Related to EMC/Isilon Acquisition

Faruqi & Faruqi, LLP, a national securities firm headquartered in New York City, is investigating the Board of Directors of Isilon Systems, Inc. for potential breaches of fiduciary duties in connection with their conduct related to the sale of the Company to EMC Corp.

The proposed transaction offers Isilon shareholders to only receive $33.85 per share in cash. The transaction is valued at approximately $2.25 billion.

Whether the Isilon’s Board of Directors breached their fiduciary duties to Isilon’s stockholders by failing to conduct an adequate and fair sales process to sell the Company prior to agreeing to this proposed transaction, whether the proposed transaction undervalues Isilon’s shares and by how much this proposed transaction undervalues the Company to the detriment of Isilon shareholders are the key focus of this investigation.
