Sterling Acquires AISS

NEW YORK, December 5, 2011 – Employment Background Screening Company Sterling Infosystems Becomes the Second Largest in the Industry

Sterling Infosystems Inc., today announced it has acquired AISS, a leading background screening company, from Acxiom Corporation (Nasdaq: ACXM). Sterling, one of the largest background screening companies in the world, now takes the second spot and is well positioned for future growth.

William Greenblatt, Founder and CEO of New York City-headquartered Sterling, said “The acquisition of AISS, one of our largest competitors, is a pivotal point in Sterling’s history because it will make us the second largest background screening company in the world. It will furthermore allow AISS to realize its full potential by being part of a company that is solely focused on what AISS is focused on – background screening.”

“Sterling Infosystems and AISS are a natural fit for each other,” said Acxiom CEO and President Scott Howe. “This agreement will benefit both companies – AISS will be able to grow and gain global footprint while Acxiom will have the ability to bring greater focus and investment to our core database and marketing services business.”

This acquisition is the latest in a string of high-profile purchases Sterling has made over the past few years, including:

• Bishops Investigative Services: The oldest privately held private investigation and corporate due diligence firm in the United States
• Abso Inc, a background screening firm based in California
• Screening International, which was comprised of American Backgrounds Inc. and Aperion Screening in the United Kingdom
• Tandem Select, a Colorado–?based background screening firm that ranked on the Inc 5000

This track record has demonstrated a successful strategy of acquisitive growth in an industry that is expected to continue its trend of consolidation.
