***Castellum Joint Venture Wins Position on $250 Million U.S. Navy Logistics IT Multiple Award Contract***

**VIENNA, Va.**, June 15, 2026 (GLOBE NEWSWIRE) – Castellum, Inc. (NYSE-American: CTM) ("Castellum" "CTM", or the "Company"), a cybersecurity, electronic warfare, and software services company focused on the federal government, announced today that its joint venture CTM JV, LLC has been awarded a contract to the Logistics IT Integration and Support ("LIIS") Capability Modernization, Deployment, and Support ("CMDS") Multiple Award Contract ("MAC"). The MAC is structured as an indefinite delivery/indefinite quantity ("IDIQ") contract vehicle, under which the United States Navy will competitively award individual task orders for specific projects, with a total maximum value of approximately $250 million.

The LIIS CMDS MAC is designed to address the need for a full range of Logistics Information Technology ("LOG IT") requirements by providing continuous CMDS of the Naval Maintenance, Repair and Overhaul ("N-MRO"), Naval Supply Chain Management ("N-SCM"), Naval Product Lifecycle Management ("N-PLM"), Logistics Integrated Data Environment ("L-IDE"), and Integration and Infrastructure ("I&I") capability solutions as part of or within the integrated platform and DevSecOps pipeline.

The United States Navy will use this MAC to procure a broad range of LOG IT services within the scope of the contract. The Navy has selected 59 companies to support modernization of the IT systems behind its maintenance and logistics operations. The tasks and detailed requirements for LOG IT services will be defined in the requirement documents for each individual task order.

"This award reflects the strength of our naval logistics IT, software engineering, and DevSecOps capabilities," said Drew Merriman, Chief Operating Officer of Castellum. "The LIIS CMDS MAC gives our team a direct lane to compete for task orders that modernize the systems the United States Navy relies on to maintain, supply and sustain the fleet."

Glen Ives, President and Chief Executive Officer of Castellum, added, "Securing a position on this vehicle deepens our already very strong relationship with the United States Navy and adds a multi-year pipeline of task order opportunities. It also reflects the continued success of our strategy to pursue and win a greater number of larger, more complex prime contracts across the United States Navy and other key customers. As we continue to qualify for and participate in larger IDIQ contract vehicles like LIIS CMDS MAC, we are expanding and strengthening our pipeline of higher-quality opportunities, which we believe will support sustained organic growth across our subsidiaries."
