5 terms
ADMACS technical
"modernize the U.S. Navy's Aircraft Data Management and Control System ("ADMACS")"
DevSecOps technical
"containerization, automated testing, DevSecOps integration, technical documentation"
DevSecOps is the practice of building security checks into the whole software creation and delivery process instead of treating security as a separate step at the end. For investors, it matters because products that find and fix vulnerabilities earlier tend to ship faster, cost less to maintain, and carry lower risk of damaging breaches or regulatory fines — much like installing quality and safety checks on a car while it’s being assembled rather than after it leaves the factory.
vertical slice technical
"implementation of an initial ADMACS "vertical slice." In this role, SSI is"
forward-looking statements regulatory
"This release contains forward-looking statements within the meaning of Section 27A"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
emerging growth company regulatory
"405) or Rule 12b-2 of the Securities Exchange Act of 1934 (17 CFR §240.12b-2). Emerging growth company"
An emerging growth company is a recently public or smaller public firm that qualifies for temporary, lighter regulatory and disclosure rules to reduce the cost and effort of being public. For investors, it means the company may provide less historical financial detail and face fewer reporting requirements than larger firms, so it can grow more quickly but also carries higher uncertainty—like buying a promising early-stage product with fewer user reviews.

Castellum Subsidiary SSI Wins $4 Million U.S. Navy ADMACS Modernization Subcontract, Expanding High-Value Navy Software Portfolio
VIENNA, Va., June 24, 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, today announced that its wholly owned subsidiary Specialty Systems, Inc. ("SSI"), has been awarded a $4 million directed subcontract to modernize the U.S. Navy's Aircraft Data Management and Control System ("ADMACS"). The award was issued under SAIC's prime contract on the General Services Administration ASTRO development/systems integration pool.
ADMACS is a mission-critical command and control application that coordinates carrier-based flight operations and aviation readiness across the fleet. Modernizing the system is central to keeping the capability reliable as the Navy's aviation systems evolve.
SSI will serve as the lead system integrator and will execute a phased modernization approach that begins with the selection and implementation of an initial ADMACS "vertical slice." In this role, SSI is responsible for technical planning, software modernization, containerization, automated testing, DevSecOps integration, technical documentation, and delivery of modernization artifacts.
This award strengthens Castellum's position across software engineering, DevSecOps, cybersecurity, and U.S. Navy mission-system sustainment by addressing one of the Department of War's most pressing challenges: extending the life of critical legacy systems while enabling faster delivery of new capability. SSI's disciplined, phased model uses representative "vertical slices" of system functionality to validate modernization across the user interface, application integration, containerized deployment, automated testing, and DevSecOps processes before scaling to broader system capabilities.
"This award reflects SSI's longstanding commitment to supporting the U.S. Navy's most critical aviation systems and our ability to modernize complex legacy applications without disrupting operational readiness," said Bob Swigon, Vice President of NAWCAD Lakehurst Operations. "ADMACS plays an important role in carrier aviation readiness, and this effort will help establish a sustainable path for future capability growth, improved affordability, and faster delivery of enhancements to the fleet as mission requirements evolve."
Glen Ives, President and Chief Executive Officer of Castellum, added, "ADMACS is another vital warfighter mission requirement that has been awarded and entrusted to CTM because of our world class professionals, who know better than anyone how to leverage leading edge
Exhibit 99.2
technology to enhance readiness and capabilities for our mission customers. ADMACS directly supports our aircraft carriers and airwings, and their ability to safely and effectively maximize flight operations and mission sorties in direct support of our national security objectives around the globe. Just as importantly for our shareholders, this win further strengthens our position as a trusted partner to the U.S. Navy, expands our portfolio of higher-value modernization work, and reinforces our confidence in delivering strong, sustained organic growth over the near and long term. Our team could not be more honored to support this crucial mission while continuing to enhance the quality, visibility, and durability of our revenue."
