January 19, 2017 – Kaplan Fox & Kilsheimer LLP (www.kaplanfox.com) is investigating claims on behalf of investors of Gigamon, Inc. (“Gigamon” or the “Company”) (NYSE: GIMO). Investors who purchased shares of Gigamon common stock during the period October 28, 2016 through January 17, 2017 may be affected.

On January 18, 2017, Gigamon announced preliminary fourth quarter and fiscal year 2016 results.  Among other things, Gigamon reported that fourth quarter revenue for the period ending December 31, 2016 would be “$84.5 million to $85 million compared to the company’s prior guidance of $91 million to $93 million [announced on October 27, 2016].”  Additionally, Gigamon announced that “[f]ourth quarter revenue fell short primarily due to lower than expected product bookings in our North America West region, as several significant existing customer accounts deferred purchasing decisions into 2017.”

Following this news, Gigamon common stock fell in price by $12.65 per share, or 28.7%, to close at $31.40 per share on January 18, 2017.
