Castellum, Inc. Announces Signing of Non-binding LOI for East Coast Government Contractor

BETHESDA, MD., January 18, 2023— Castellum, Inc. (NYSE-American: CTM), a cybersecurity, electronic warfare, data analytics, software, and IT services company focused on the federal government, announces that it has signed a non-binding letter of intent to acquire an East Coast based government contractor which focuses on cybersecurity, data analysis, and other IT services for federal civilian agencies. Subject to customary due diligence and the execution of a definitive purchase agreement, Castellum expects to close the transaction within the next 90 days.

The potential acquisition, when combined with Castellum’s other, previously announced, pending non-binding LOI is expected to boost Castellum to over a $60 million annualized revenue run-rate versus a current $44 million run-rate based on announced Q3 2022 results.

“We are pleased to announce the execution of another LOI to extend our buy-and-build strategy,” said Mark Fuller, President and CEO of Castellum. “This additional work in Federal Civilian agencies, will further broaden Castellum’s customer base, while adding new capabilities and leveraging past performance enjoyed by our Department of Defense (DoD) customers with whom we have strong and growing relationships. We also are talking with other companies that have business with DoD and Federal Civilian agencies, about potential acquisition as we are working to double our top line run rate in 2023.”
