Resilient Infrastructure: OSS and NextNav Q4 Earnings Highlight Defense Growth

The Q4 2025 earnings cycle for One Stop Systems (OSS) and NextNav (NN) has provided a clear signal to the defense and aerospace sectors: the future of battlefield superiority lies in resilient, decentralized infrastructure. As the Department of Defense (DOD) increasingly prioritizes "AI at the edge" and resilient positioning, navigation, and timing (PNT), these two companies have emerged as pivotal players in the transition from traditional cloud-based architectures to ruggedized, autonomous-ready systems. While the broader Q4 2025 earnings cluster includes diverse entities such as Kaltura (video platforms), Citi Trends (retail), and Longeveron (biotechnology), the strategic implications for the Space & Defense sector are concentrated in the reports from One Stop Systems and NextNav.

One Stop Systems (OSS) has spent the latter half of 2025 solidifying its position as a leader in "AI on the Fly." Under the leadership of CEO Mike Knowles, who brought decades of defense expertise from Cubic and Raytheon, the company has successfully pivoted from a broad commercial focus to a high-margin defense-centric model. During the Q4 call, OSS highlighted the growing demand for its ruggedized servers, which are designed to bring data-center-level computing power to the tactical edge—specifically for autonomous vehicles, electronic warfare (EW) suites, and advanced sensor fusion platforms. The company’s ability to package NVIDIA-grade GPU performance into small, heat-dissipating, and vibration-resistant form factors has made it a preferred partner for Tier 1 defense contractors. The strategic focus on "AI on the Fly" addresses the critical need for real-time data processing in contested environments where low-latency decision-making is a matter of survival.

Parallel to the growth in edge computing is the urgent need for resilient navigation. NextNav’s Q4 2025 earnings call focused heavily on its ongoing regulatory and strategic push to provide a terrestrial alternative to the Global Positioning System (GPS). With GPS signals increasingly vulnerable to jamming and spoofing in global conflict zones like Ukraine and the Middle East, the DOD and the Department of Homeland Security (DHS) have accelerated their search for a "Plan B." NextNav’s proposal to the FCC to repurpose the 900 MHz band for a nationwide terrestrial PNT network is the cornerstone of this effort. By utilizing high-power terrestrial transmitters, NextNav can provide a PNT signal that is significantly stronger and more difficult to jam than the relatively weak signals coming from satellites in Medium Earth Orbit (MEO). The Q4 report indicated that NextNav is making significant headway in its testing phases with defense partners, positioning its spectrum assets as a critical component of national security infrastructure.
