Interface Security Systems LLC, St. Louis, Mo., has acquired the assets of Hawk Security Services from its parent, Progressive Concepts Inc. Hawk Security is one of the largest independent security companies in Texas with offices in Dallas/Fort Worth, San Antonio and Tyler. The company provides monitored electronic security services to more than 12,500 subscribers, approximately 75 percent residential and 25 percent commercial. Hawk also provides specialized infant location monitoring, identification and protection systems, sold under the trademark Hawk Healthcare, to hospitals throughout Texas.

While details of the transaction are confidential, Interface’s investors, lead by Dallas-based equity sponsor SunTx Capital Partners, provided equity financing for the transaction and CapitalSource LLC arranged the debt financing.

Interface Holdings, currently ranked No. 13 in the SDM 100, provides installation, maintenance and monitoring services to both commercial and residential customers in Illinois, Indiana, Missouri, Arkansas, Tennessee, Louisiana, Mississippi and Texas, as well as in California through its subsidiary, The Greater Alarm Company. The company also provides fully integrated intrusion, fire, managed access control and interactive video surveillance systems to large commercial customers.

“The acquisition of Hawk Security Services represents the ninth transaction completed by Interface so far in 2005,” said Michael Shaw, CEO of Interface Security Systems Holdings Inc. “During the first half of 2005 we completed eight smaller in-market acquisitions that added significant scale to our existing operations in Mississippi, Louisiana and California.”

Shaw added, “Hawk Security not only gives us a major presence in the vibrant and fast-growing Dallas/Fort Worth area, but also adds market share to our existing brand operations in East Texas as well as a new office in San Antonio.”

Interface hired all of the approximately 80 Hawk Security employees, said Mike McLeod, Interface president and CEO.
