Xos Reports Record Gross Margin and Lowest Operating Loss in Company History since Going Public, Anchored by Multi-Product Business Lines

Record-lows in operating loss and non-GAAP operating loss since going public, achieving reductions of nearly 50% and 67.2% year-over-year, respectively.

Generated quarterly gross margin of $4.3 million, expanding margins to 38.6%

Delivered a Q1 record of 95 units, including 63 powertrains for Blue Bird school buses, more than 3 times the prior-year quarter

LOS ANGELES, May 14, 2026 (GLOBE NEWSWIRE) -- Xos, Inc. (NASDAQ:XOS) ("Xos" or the "Company"), a leading energy storage and fleet electrification solutions provider, today reported financial results for the first quarter ended March 31, 2026. Building on a year of disciplined execution and consistent operational improvement, Xos opened 2026 with its highest quarterly gross margin and lowest operating loss in Company history, reinforcing the durability of its operating model and the strength of its multi-product platform spanning vehicles, powertrains, and energy storage.

First Quarter Highlights:

• Xos delivered 95 units, including leases, and generated $11.2 million in revenue in the first quarter, compared to 29 units and $5.9 million in Q1 2025, as the Company executed its strategic focus on powertrain and hubs production.
• Gross margins improved to a record-high 38.6%, compared to 20.6% in Q1 2025. Non-GAAP gross margins also reached a record 37.8%, compared to 15.0% in Q1 2025. The increase was driven by a shift in product mix towards high-margin powertrains and hubs.
• Xos reported record-lows in operating loss and non-GAAP operating loss since going public, achieving reductions of 49.5% and 67.2% year-over-year, respectively. Operating loss improved to $4.7 million, compared to $9.3 million in Q1 2025, and non-GAAP operating loss of $2.6 million in Q1 2026, compared to $8.1 million in Q1 2025.
• Operating expenses decreased by $1.5 million, or 14.0% year-over-year. First quarter operating expenses fell to $9.0 million compared to $10.5 million in Q1 2025, driven by cost discipline across the organization.
• EBITDA improved by $4.7 million, or 53.4% year-over-year. First quarter EBITDA was a loss of $4.1 million compared to a loss of $8.8 million in Q1 2025. Adjusted EBITDA improved by $5.2 million, or 72.4% year-over-year. First quarter adjusted EBITDA was a loss of $2.0 million compared to a loss of $7.2 million in the first quarter of 2025.

Platform and Product Milestones:

• Xos Hub™ energy storage proving reliability at scale. Xos Hub units deployed across customer fleets have now charged gigawatt-hours of energy in the aggregate, and the most active individual units have completed thousands of charge cycles each, proving the reliability and durability of Xos's mobile energy storage technology in demanding real-world conditions.
• Next-generation Hub variants in development. The Company launched the Xos Hub 210 kWh, Xos Hub 420 kWh and Xos Hub 630 kWh models; the 420 kWh option began production during the quarter. These next-generation variants expand the addressable market for the Xos Hub across a broader range of fleet sizes and charging use cases.
• During the first quarter of 2026, multiple Xos customer fleets surpassed millions of cumulative miles driven on their Xos vehicles, a milestone that validates the long-term reliability, performance, and total cost of ownership advantage of the Xos platform.
• Last year Xos announced the industry's most competitive electric truck chassis, priced below $100,000. During the first quarter of 2026, Xos began offering its electric truck chassis at $99,000, making it the most competitively priced battery-electric commercial vehicle chassis on the market. This pricing positions Xos to capture accelerating demand as fleet operators evaluate electrification on pure economics, regardless of the evolving incentive landscape.

"Q1 was a defining proof point for this team. We delivered the highest gross margin in our history as a public company and the lowest operating loss since going public. Our Hubs have now charged gigawatt-hours of energy. Our customers have logged millions of miles. Our powertrains are powering Blue Bird school buses operating around the country. And we're now selling the most competitively priced electric truck chassis in the industry, for under $100,000. These results reflect the strength of our engineering team, the discipline of our supply chain team, and the execution of our sales organization. Xos is building a multi-product platform that wins on reliability, wins on economics, and wins regardless of where the incentive landscape goes, and that is exactly the company we set out to build," said Dakota Semler, Chief Executive Officer of Xos.

"The first quarter reflects disciplined execution of the operating framework we've put in place over the past year," said Liana Pogosyan, Chief Financial Officer. "We delivered record gross margins of 38.6% and significantly reduced operating loss, with GAAP operating loss improving by nearly 50% and non-GAAP operating loss by 67% year-over-year, while continuing to scale revenue. Importantly, these results are driven by structural improvements across sourcing, inventory management, and cost control—not one-time actions. Our focus going forward is unchanged — sustaining the momentum, scaling efficiently, and delivering consistent margin expansion and operating leverage."

Non-GAAP Financial Measures

The financial information in this press release has been presented in accordance with United States generally accepted accounting principles ("GAAP") as well as on a non-GAAP basis to supplement Xos's unaudited condensed consolidated interim financial results. Xos's non-GAAP financial measures include operating cash flow less CapEx (Free Cash Flow), non-GAAP operating loss, non-GAAP gross profit and Adjusted EBITDA, which are defined below.

"Operating cash flow less CapEx (Free Cash Flow)" is defined as net cash provided by (used in) operating activities minus purchases of property and equipment.

"Non-GAAP operating loss" is defined as loss from operations adjusted for stock-based compensation, inventory write-downs and physical inventory and other adjustments.

"Non-GAAP gross profit" is defined as gross profit (loss) minus inventory write-downs and physical inventory and other adjustments.

"Adjusted EBITDA" is defined as EBITDA (earnings before interest, taxes, depreciation & amortization) minus change in fair value of derivatives, change in fair value of earn-out shares liability, and stock based compensation.

Xos believes that the use of operating cash flow less CapEx (Free Cash Flow), non-GAAP operating loss, non-GAAP gross profit, and Adjusted EBITDA reflects additional means for management and investors to use when evaluating Xos's ongoing operating results and trends. The presentation of these measures should not be construed as an inference that Xos's future results will be unaffected by unusual or non-recurring items. It is important to note Xos's computation of operating cash flow less CapEx (Free Cash Flow), non-GAAP operating loss, non-GAAP gross profit, and Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies, because not all companies may calculate operating cash flow less CapEx (Free Cash Flow), non-GAAP operating loss, non-GAAP gross profit, and Adjusted EBITDA in the same fashion. Non-GAAP information is not prepared under a comprehensive set of accounting rules and therefore, should only be read in conjunction with financial information reported under GAAP when understanding Xos's operating performance. A reconciliation between historical GAAP and non-GAAP financial information is provided in this press release.
