GTCR-Backed Six3 Systems Buying Harding Security

Six3 Systems Inc., a provider of national security and defense intelligence services, has agreed to acquire Harding Security Associates Inc., a provider of identity intelligence, forensics analysis and security services to the federal government. No financial terms were disclosed for the deal, which is expected to close next month. Six3 Systems is a portfolio company of GTCR.

GTCR, one of the nation’s leading private equity firms, and Six3 Systems, Inc. (“Six3”), a GTCR portfolio company that specializes in providing national security and defense intelligence services, today announced a definitive agreement to acquire Harding Security Associates, Inc. (“HSA”).

HSA is a leading provider of identity intelligence, forensics analysis and security services to the federal government. With more than 350 highly trained employees, HSA is at the forefront of the Department of Defense’s (“DoD”) biometric-enabled intelligence analysis and forensics mission. The Company also provides mission-critical intelligence and counter-intelligence training and security services to the DoD and key civilian agencies.

“We view this deal as a critical first step in achieving our long term objective of building a highly specialized national security services provider that is focused on solving our nation’s most pressing security challenges domestically and abroad,” said Robert Coleman, Chief Executive Officer of Six3. “HSA is working at the heart of the identity intelligence and forensics mission, and I look forward to continuing to build that capability under Six3 Systems.”

“Since we announced the formation of Six3, we have actively targeted providers of specialized services in high-growth areas within the defense budget. We believe HSA fits squarely within this strategy,” added GTCR Principal Craig Bondy. “GTCR and Six3’s investment in HSA is an excellent example of our partnering with an industry-leading executive and pursuing strategic acquisitions.”

“I am very pleased to have Harding Security Associates join forces with Six3 Systems,” commented Major General Robert A. Harding, USA (Ret.), Chief Executive Officer of HSA. “I believe this acquisition will provide enhanced career opportunities for our people while continuing our track record of outstanding service and support to our customers.”

Kirkland & Ellis LLP served as legal counsel to GTCR and Six3 Systems. KippsDeSanto & Co. acted as exclusive financial advisor to HSA. The transaction, which represents the first acquisition for Six3 Systems, is expected to close in July.
