OSS Receives Award Supporting U.S. Missile Defense Agency

ESCONDIDO, Calif., Sept. 16, 2026 (GLOBE NEWSWIRE) — One Stop Systems, Inc. (OSS or the Company) (Nasdaq: OSS), a leader in rugged Enterprise Class compute for artificial intelligence (AI), machine learning (ML) and sensor processing at the edge, today announced an approximately $400,000 award from a leading U.S. defense prime contractor for advanced modeling and simulation of U.S. missile defense systems in support of the U.S. Missile Defense Agency.

The award includes OSS’s latest generation 4UP Max PCIe expansion platform configured with eight NVIDIA RTX PRO 6000 Blackwell GPUs and represents the first deployment of this configuration with the customer. The system is intended to provide a significant compute technology upgrade for advanced missile defense modeling and simulation workloads.

OSS’s 4UP Max is a high-performance PCIe expansion platform engineered to support up to eight high-performance PCIe accelerators in compute-intensive enterprise-class computing and artificial intelligence environments. The platform helps deliver the compute density, power and cooling required for increasingly sophisticated modeling, simulation and analysis applications.

“Advanced missile defense simulation requires significant computing performance to accurately model increasingly complex threats and operating environments,” said Mike Knowles, President and CEO of OSS. “This award demonstrates the value of our latest-generation computing platforms for some of the defense industry’s most demanding simulation workloads and, we believe, further validates our ability to support critical national defense applications. We are experiencing increased demand for high-end simulation environments where the accurate representation of complex threats and operating conditions is critical.”

As defense systems and mission environments become increasingly sophisticated, advanced modeling and simulation applications require greater levels of compute performance, density and scalability. OSS believes these trends are creating additional opportunities for its enterprise-class computing platforms across missile defense and other advanced defense applications, including next-generation homeland missile defense architectures and fifth- and sixth-generation platform performance modeling.
