**Castellum, Inc.'s Subsidiary Specialty Systems, Inc. Adds IT Services for GSA MAS Contract**

VIENNA, Va., Oct. 14, 2025 (GLOBE NEWSWIRE) -- Castellum, Inc. (NYSE-American: CTM) ("Castellum" or "CTM"), a cybersecurity, electronic warfare, and software engineering services company focused on the federal government, announces that its subsidiary <u>Specialty Systems, Inc.</u> ("<u>SSI</u>") has added <u>Special Item Number ("SIN") 54151S to a new General Services Administration ("GSA") Multiple Award Schedule ("MAS")</u> contract. <u>SIN 54151S now allows SSI to bid on competitive contracts</u> related to information technology professional services. It also allows us to onboard our joint venture with <u>SSI's protégé, Epic Systems, Inc. ("Epic")</u>, to GSA MAS SIN 54151S now that both Epic and SSI have contracts on the 54151S SIN.

"We have been implementing a very specific strategy to ensure we can compete for more full and open opportunities as a large business, while maintaining access to small business set-asides through our mentor-protégé joint ventures. This is another tangible step toward executing that strategy and allowing us to compete in more markets with a wider variety of services. Thanks to the hard work of SSI's leadership and our CTM professionals, we are now able to compete for information technology opportunities on GSA MAS. We can respond to Requests for Quotations ("RFQs") and Requests for Proposals ("RFPs") tied specifically to SIN 54151S. This is also a prerequisite for being able to leverage our joint venture agreements on the GSA MAS schedule," said <u>Drew Merriman, Chief Operating Officer of Castellum</u>.

These forward-looking statements are subject to risks, uncertainties, and other factors, many of which are outside of the Company's control, that could cause actual results to differ materially from the results expressed or implied in the forward-looking statements, including, among others: the Company's ability to compete against new and existing competitors; its ability to effectively integrate and grow its acquired companies; its ability to identify additional acquisition targets and close additional acquisitions; the impact on the Company's revenue due to a delay in the U.S. Congress approving a federal budget, operating under a prolonged continuing resolution, government shutdown, or breach of the debt ceiling, as well as the imposition by the U.S. government of sequestration in the absence of an approved budget; the ability of the U.S. federal government to unilaterally cancel a contract with or without cause, and more specifically, the potential impact of the U.S. DOGE Service Temporary Organization on government spending and terminating contracts for convenience.
