Ixia Announces CEO Transition and Appoints Errol Ginsberg as Acting CEO

Appoints Alex Pepe as Chief Operating Officer

CALABASAS, CA, October 24, 2013 — Ixia (NASDAQ: XXIA) today announced that Vic Alston has resigned as its President and CEO and as a member of its board of directors following a determination by the Ixia audit committee that although he had attended Stanford University, he had misstated his academic credentials, incorrectly claiming to have received a B.S. and a M.S. in Computer Science, and had misstated his age and early employment history.

The board has appointed Errol Ginsberg, Ixia’s chairman of the board, founder and former CEO as acting CEO (in addition to his current role as chief innovation officer), and Alex Pepe, senior vice president, strategy, as chief operating officer.

Ixia also reaffirmed its revenue guidance for the third quarter ended September 30, 2013 and expects revenue to be above the midpoint of its previously stated guidance range of $112 million to $117 million. The company will issue financial results for its third quarter ended September 30, 2013 after the U.S. markets close on Tuesday, October 29, 2013, followed by a conference call at 2:00 p.m. Pacific time (5:00 p.m. Eastern time).

“Vic made many positive contributions to Ixia over the past nine years, and we are saddened by the circumstances of his resignation,” said Ginsberg. Ginsberg continued, “I am pleased with Alex’s appointment as chief operating officer. Alex’s broad experience and leadership skills will be of great value in helping Ixia through this transitional period. Since joining Ixia 16 months ago, Alex has done a great job leading our visibility product team and has been instrumental in developing our monitoring strategy.”

Pepe joined Ixia in June 2012 through the acquisition of Anue Systems, where he served as President and CEO. He has more than 25 years of experience in the technology industry, with 15 years in executive leadership roles. Prior to joining Anue, Pepe spent six years as a senior vice president of Freescale Semiconductor where he led global operations and was responsible for manufacturing, procurement, and supply chain systems.

The Board plans to commence a search to identify a permanent CEO for the company.
