Strategic Acquisitions

Castellum

acquired Lexington Solutions Group,

a $4 million government contractor focused on information operations and information warfare, in April 2022, expanding the company's growth opportunities and bringing B. Boyd Brown to the Company to help lead business development given his past experience with Booz Allen Hamilton.

In March 2023, Castellum closed its

acquisition of Global Technologies Management Resources, Inc.,

a $10 million revenue government contractor based in Hollywood, Maryland supporting the U.S. Navy. This acquisition increased Castellum's revenue run rate to $50 million and added significant new capabilities and resources to the Company including GTMR’s President Jim Morton.

Castellum is pursuing other strategic opportunities as well with a goal of doubling the size of the company to $100 million in revenue over the next 12 months.
