Xos Hub Surpasses 1 GWh of Cumulative Energy Delivered

A single Xos Hub™, a mobile, grid-independent energy storage and charging system, has surpassed one gigawatt-hour (GWh) of cumulative energy delivered, marking a significant milestone for Xos, Inc. (NASDAQ: XOS). This achievement provides robust, multi-year field evidence of the Hub's durability under continuous, real-world use, which is driving the company's growth across new markets and products.

Over the past year, the Xos Hub has demonstrated exceptional performance, delivering 1,020,143.6 kWh of energy in the field. It has operated near-continuously since entering heavy-duty service in early 2025, averaging between 1,800 to 2,000 kWh of energy delivery per day across more than 33,600 charging sessions. The company’s fleet of deployed Hubs has collectively delivered over 5 GWh of energy, underscoring the scalability and reliability of the platform.

“Reaching a gigawatt-hour from a single Hub gives us multi-year data on how this platform performs under continuous, real-world use. That track record is the foundation for how we are growing this business across new products and markets, and it shows customers across multiple industries why they can rely on it,” said Dakota Semler, Chief Executive Officer of Xos.

The milestone reflects Xos’s commitment to delivering reliable, high-throughput commercial charging without the need for permanent infrastructure or utility upgrades. The company has expanded its Hub to higher capacity and launched the megawatt-scale Power Hub to meet the growing demand for energy storage and flexible charging solutions.

In January 2026, Xos introduced Hub capacity tiers up to 630 kWh, broadening the range of applications the platform can serve. In June 2026, the Power Hub was launched, a containerized system that scales the Hub architecture to megawatt-scale power for large loads, available in 1.2, 2.5, and 4.0 MWh configurations. Xos has also made significant progress in utility and defense markets, securing a follow-on order from Xcel Energy for three Hubs in Colorado and a prototype Other Transaction Agreement from the U.S. Air Force.

The Xos Hub’s durability and proven performance are also supporting the company’s safety certification efforts. In August 2026, the Hub achieved UL 2202 certification for fleet energy storage systems, enhancing its reliability and safety credentials.

The growing demand for energy storage and flexible charging solutions is driven by the rapid expansion of U.S. energy storage installations. According to Wood Mackenzie and the American Clean Power Association, U.S. energy storage installations reached a record 18.9 gigawatts in 2025, up 52% from the previous year. However, the process of connecting new capacity to the grid remains a bottleneck, with roughly 2,061 gigawatts of generation and storage waiting in U.S. interconnection queues, and a typical project taking more than five years to reach commercial operation.

The Xos Hub stands out as a deployable, grid-independent system that can add power without waiting on utility upgrades. The durability behind this milestone is helping the company broaden the platform to serve more of this growing demand.

As Xos continues to scale the Hub platform into higher-capacity systems and large-scale power, the company plans to deepen its presence across fleet, utility, industrial, and defense markets. The field-validated durability of the Xos Hub is expected to grow into a lasting competitive advantage, providing buyers with measurable evidence of its performance and reliability.

This milestone is a testament to Xos’s commitment to innovation and reliability in the evolving electric vehicle and energy storage landscape. As commercial fleets, utilities, and energy-intensive operations move to electrify, the Xos Hub is positioned to play a crucial role in meeting their charging and energy storage needs.
