SHAREHOLDER ALERT: Shareholder Rights Law Firm Johnson & Weaver, LLP Has Filed a Class Action Lawsuit against Imperva, Inc. and Certain Officers

SAN DIEGO--(BUSINESS WIRE)--

Shareholder rights law firm Johnson & Weaver, LLP announced today that it filed a class action lawsuit in the United States District Court for the Northern District of California on behalf of purchasers of Imperva, Inc. IMPV publicly traded securities between May 2, 2013 and April 9, 2014 (the “Class Period”). Imperva develops, markets, sells, services, and supports data center security solutions that protect high value applications and data assets in physical and virtual data centers.

The complaint alleges that during the Class Period, defendants issued materially false and misleading statements regarding the Company's operations and business and its financial results. The complaint alleges that, as a result of defendants' false statements, Imperva securities traded at artificially inflated prices during the Class Period, with its stock price reaching a high of $65.53 per share on March 6, 2014. The complaint alleges that certain of the Company's officers and directors were able to sell $25.9 million worth of their Imperva stock at inflated prices, including $11.8 million worth of stock sold by the Chief Executive Officer and the Chief Financial Officer.

On April 9, 2014, Imperva reduced its first quarter revenue guidance to $31.0M to $31.5M from its previous outlook of $34.0M to $35.0M. Prior to the Company's warning, analysts' consensus revenue estimate was $36.5M to $37.0M. Imperva stated that the lowered revenue guidance was impacted primarily by extended sales cycles on deals over $100,000. As a result of this news, Imperva's stock plummeted $21.73 per share to close at $28 per share on April 10, 2014, a one-day decline of nearly 44% on volume of 10.9 million shares.

Plaintiff seeks to recover damages on behalf of all purchasers of Imperva publicly traded securities during the Class Period.
