LOS ANGELES, Aug. 17, 2026 (GLOBE NEWSWIRE) -- Xos, Inc. (NASDAQ: XOS) ("Xos" or the "Company"), a leader in electric commercial vehicles and mobile charging solutions, today announced that it has been awarded a prototype Other Transaction Agreement (OTA) by the United States Air Force to develop and deliver a deployable mobile charging solution for electrified support equipment and vehicles. The award, made through the Air Force Global Strike Command Rapid Capabilities Division 2026 Showcase, marks Xos's entry into the defense market and reflects the growing cross-sector demand for the Company's mobile energy storage platform across commercial fleets, ports, municipalities, and now national defense.

The award lands in a fast-growing market: the global military power solutions sector is projected to reach $19.87 billion by 2033, growing at 7.7% annually as armed forces prioritize portable, high-efficiency energy across their operations. Xos meets that demand head-on with a commercially proven mobile energy platform, purpose-built to deliver high-capacity, grid-independent power wherever it is needed, without waiting on permanent infrastructure.

Award at a Glance:

• First U.S. Air Force contract for Xos. Awarded under the AFGSC Rapid Capabilities Division Showcase, a competitive, merit-based program that rapidly evaluates and fields emerging commercial technologies, the agreement establishes Xos as a defense technology provider. It validates the Xos Hub™ as a deployable power solution capable of meeting U.S. Department of Defense mission requirements and opens a new addressable market for the Company's mobile energy platform.
• Modified for military-grade performance. Under the prototype agreement, Xos will adapt its Xos Hub™ mobile battery energy storage system to deliver reliable, high-capacity, standards-based charging for electrified support equipment and vehicles, extending the same grid-independent, infrastructure-free capability that commercial fleets rely on to demanding field environments.
• A platform built for scale across sectors. The AFGSC award extends the Xos Hub customer base beyond commercial fleets and municipal operators into the U.S. defense ecosystem, adding to a growing pipeline that spans port authorities, utilities, and federal grant programs. It validates the Hub's role as infrastructure-grade mobile power for the most demanding operators in the world.
• American-made. Designed in California and manufactured in Tennessee, the system will undergo primary assembly and integration at Xos's Byrdstown, Tennessee facility, reflecting a fully domestic design-to-build model that delivers purpose-built energy solutions from a U.S. production base.
  

"This award marks a strategic inflection point for Xos. When the United States Air Force evaluates the market and selects our technology, it confirms what we set out to build from day one: a mobile energy platform proven in commercial operations that can meet the most demanding mission requirements in the field. Defense is a significant new addressable market for the Xos Ecosystem, and it is one where our advantages compound: American design and manufacturing, proven reliability, and deployable power that needs no fixed infrastructure. This is how Xos scales, carrying a platform already trusted across multiple sectors into the highest-stakes markets in the world," said Dakota Semler, Chief Executive Officer of Xos.

The opportunity is substantial. The U.S. Department of Defense is the largest institutional consumer of energy in the United States, and the U.S. Army has committed to fielding microgrids at every installation and an all-electric non-tactical vehicle fleet by 2035. Xos is built to help power that shift: the Xos Hub delivers high-capacity, deployable energy with no permanent infrastructure, the same capability already proven in the field today, now adapted for defense operations.

"This award reflects disciplined execution across engineering, operations, and manufacturing. As a non-traditional contractor, we move fast and we deliver, adapting a commercially proven product for a new mission and building it right here in Tennessee. It is a powerful demonstration of the flexibility of our platform and the strength of our American manufacturing base" said Giordano Sordoni, Co-Founder and Chief Operating Officer of Xos.

With a period of performance extending into late 2027, the agreement positions Xos to demonstrate the versatility of the Xos Hub across new environments while deepening its domestic manufacturing capabilities. The Company intends to build on this milestone as it pursues additional opportunities to bring its mobile charging and energy storage technology to fleets and operators seeking reliable, deployable, infrastructure-free power.
