Calista Acquires STG Incorporated as Newest Subsidiary

Leading Remote Heavy Construction Company in Alaska

(Anchorage, Alaska) – Calista Corporation announced today the acquisition of STG Incorporated. In the last 20 years STG has earned a solid reputation while operating throughout Alaska, from hot and sunny summer days to frigid winter nights.

STG has installed approximately 80 percent of the utility-scale wind projects currently in operation across the state, including crane support for the Fire Island Wind project near Anchorage and in rural communities throughout Alaska. They also completed the 34-site tower and control buildings for the massive DeltaNet Project for United Utilities, Inc. in southwest Alaska. STG is also the premier pile foundations contractor for western and interior Alaska. Additionally, the team at STG provides deep experience with diesel power generation projects, bulk fuel systems and other renewable energy projects.

“STG stands out in Alaska as a proven company with dedicated employees, led by Jim and Sandy St. George,” said Calista Corporation President/CEO Andrew Guy. “Calista continues to strengthen and grow with complementary acquisitions. That is one of our key obligations to our shareholders.”

“When we first founded the company in Kotzebue, known then as St. George Construction, our focus was operating as true Alaskans – with honesty, hard work and solutions to any challenge,” said STG President Jim St. George. “Our team is excited to join Calista’s operations. We are tasked with continuing our strong Alaska Native hire rates while positively contributing to Calista’s revenues.”

The acquisition also includes Alaska Crane, Ltd., Terra Foundations, Inc. and Gambell Properties, LLC. Alaska Crane provides crane equipment and operators for nearly any sized project. Their equipment includes the largest crane in Alaska, currently working on the Blue Lake Hydroelectric project in Sitka. Three years ago Calista acquired Brice, Incorporated and Yukon Equipment, Inc.
