Exhibit 99.1

Xos Delivers Third Consecutive Quarter of Positive Operating and Free Cash Flow, Accelerates Platform Expansion Across Vehicles, Powertrains, and Energy Storage

Delivered first production powertrains for Blue Bird school buses

Achieved third consecutive quarter of positive operating cash flow and free cash flow, ending 2025 with $14.0 million in cash — up 28% year-over-year

Reduced full-year operating expenses by $14.0 million (28.2% YoY) and cut full-year EBITDA loss by more than half — from $42.2 million to $21.0 million

LOS ANGELES, CA – March 26, 2026 – Xos, Inc. (NASDAQ: XOS) ("Xos" or the "Company"), a leading energy storage and fleet electrification solutions provider, today reported financial results for the fourth quarter and full year ended December 31, 2025. Building on a year of disciplined execution and consistent operational improvement, Xos closed 2025 with its third consecutive quarter of positive operating cash flow and positive free cash flow, reinforcing the durability of its operating model and the strength of its multi-product platform spanning vehicles, powertrains, and energy storage.

Fourth Quarter Highlights:

•Xos achieved positive net cash provided by operating activities and positive free cash flow of $2.4 million in Q4, marking three straight quarters of cash-positive operations. This performance reflects meaningful improvements in the Company's operating model, including faster inventory turnover and more efficient receivables collection, which have driven stronger cash generation and improved working capital efficiency.

•Operating expenses reduced by 34.6% year-over-year. Fourth quarter operating expenses decreased by $3.8 million compared to Q4 2024, driven by continued headcount efficiency and cost discipline across the organization.

•Operating loss reduced by 33.2%. The Company reported an operating loss of $9.7 million and a non-GAAP operating loss of $4.6 million in Q4 2025, compared to an operating loss of $14.6 million and a non-GAAP operating loss of $6.4 million in Q4 2024 — a 27.1% improvement in non-GAAP operating loss.

•Xos delivered 34 units and generated $5.2 million in revenue in the fourth quarter, compared to 51 units and $11.5 million in Q4 2024 as the Company began shifting focus and allocating resources to powertrain production as opposed to stepvans and chassis.

•Gross margins decreased to negative 50.5%, compared to negative 32.4% in Q4 2024. Non-GAAP gross margins were 5.2%, compared to 23.2% in Q4 2024. The decrease was driven by higher

inventory reserves and associated write-downs due to changes in the Company's commercialization strategy, as well as higher warranty reserves.

•EBITDA improved to a loss of $8.5 million from a loss of $13.4 million in Q4 2024, and adjusted EBITDA improved to a loss of $7.0 million from a loss of $12.0 million in the prior year.

Full Year 2025 Highlights:

•Xos delivered 328 units in 2025, a 10% increase from 297 units in 2024. Revenue was $46.0 million compared to $56.0 million in 2024, with the year-over-year decline in revenue per unit reflecting a strategic shift in product mix toward stripped chassis and powertrain units as opposed to complete stepvans.

•Second consecutive full year of positive gross margin. The Company achieved a gross margin of 5.9% in 2025, compared to 7.1% in 2024, and non-GAAP gross margin of 8.8%, compared to 18.0% in 2024.

•Operating expenses reduced by $14.0 million, or 28.2%. Full-year operating expenses declined to $35.8 million from $49.8 million in 2024, underscoring sustained structural cost improvement and a leaner, more efficient operating model.

•Operating loss narrowed by 27.9%. The Company reported a full-year operating loss of $33.1 million and a non-GAAP operating loss of $24.3 million, compared to an operating loss of $45.9 million and a non-GAAP operating loss of $32.1 million in 2024 — a 24.1% improvement in non-GAAP operating loss.

•EBITDA loss cut by more than half. Full-year EBITDA improved to a loss of $21.0 million from $42.2 million in 2024 — a $21.2 million improvement. Adjusted EBITDA improved to a loss of $23.5 million from $34.8 million, a 33% improvement reflecting the compounding benefits of cost discipline and operational efficiency.

•Cash position strengthened to $14.0 million. Xos ended the year with $14.0 million in cash and cash equivalents, up from $11.0 million at year-end 2024 — a 28% increase highlighting growing financial flexibility and momentum toward long-term sustainable growth.

•First production powertrains delivered for Blue Bird school buses. Xos delivered its first production electric powertrains to Blue Bird Corporation, expanding beyond commercial vehicles into the school bus market and validating Xos's powertrain technology platform as a scalable OEM solution.

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 began development of the Xos Hub 210 kWh, Xos Hub 420 kWh and Xos Hub 630 kWh models, which will enter production in 2026. These next-generation variants expand the addressable market for Xos Hub across a broader range of fleet sizes and charging use cases.

•Customer fleets surpass millions of cumulative miles. Subsequent to year end, multiple Xos customer fleets surpassed millions of cumulative miles driven on their respective Xos vehicles — a milestone that validates the long-term reliability, performance, and total cost of ownership advantage of the Xos platform.

•Industry's most competitive electric truck chassis — priced below $100,000. Subsequent to year end, Xos began offering its electric truck chassis at $99,000, making it the most competitively priced battery-electric commercial stripped 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.

"2025 was a defining year for this company," said Dakota Semler, Chief Executive Officer of Xos. "Our flagship energy-storage solution, the Xos Hubs, have now charged gigawatt-hours of energy across thousands of cycles. We shipped our first production powertrains to Blue Bird. Our customers have driven millions of miles on Xos vehicles. And we're now offering the most competitively priced electric truck chassis in the industry — below $100,000. Three consecutive quarters of positive free cash flow proved the model works. But what excites me most is what this team is building: a multi-product platform that wins on reliability, wins on economics, and wins regardless of where the incentive landscape goes. The companies that thrive in this next chapter will be the ones whose products stand on their own — and that's exactly what we've built."

"The financial progress in 2025 speaks for itself," said Liana Pogosyan, Chief Financial Officer of Xos. "Three consecutive quarters of positive free cash flow, EBITDA loss cut by more than half, a 28% reduction in full-year operating expenses, and $14 million in cash to start 2026. We restructured our balance sheet, extended our financial runway and unlocked over $20 million in long-term savings — all while this team continued to execute. The discipline is structural, not situational, and it positions us well for the year ahead."

(1) For further information about how we calculate Non-GAAP financial measures, such as Non-GAAP gross profit, Non-GAAP operating loss, Adjusted EBITDA, and free cash flow, see below for the reconciliations of GAAP to non-GAAP financial measures provided in the tables included in this release.

Balance Sheet and Capital Structure:

•$20.7 million in estimated cash savings from Mesa facility lease termination. In 2025, Xos reached an agreement to terminate the lease on its Mesa, Arizona manufacturing facility, unlocking an estimated $20.7 million in cash savings through 2033 and focusing production resources on its Byrdstown, Tennessee operations.

•Convertible note restructured with extended runway through 2028. In 2025, the Company amended its outstanding Convertible Note with $20 million in initial principal amount, which was originally due August 2025, to spread principal payments over ten quarterly installments through February 2028 — enhancing near-term liquidity and extending financial runway.

•Additional capital raised under ATM program. Xos raised $2.4 million, net of offering costs, under its at-the-market offering program during 2025, further reinforcing near-term liquidity.

2026 Outlook:

Xos’s outlook for 2026 is as follows:

Revenue

$40.0 to $50.0 million

Non-GAAP operating loss (1)

$11.9 to $13.3 million

Unit Deliveries (2)

350 to 500 units

____________________________

(1) This press release does not provide a forward-looking reconciliation from Non-GAAP operating loss to net loss, the most directly comparable GAAP measure, due to the uncertainty and the potential variability of inputs of the financial information. For the same reason, we are unable to address the probable significance of the unavailable information.

(2) Unit deliveries forecast includes our powertrain and Xos Hub products, stepvans and stripped chassis.

The outlook provided above is based on management beliefs and expectations as of the date of this press release. The results are based on assumptions that are believed to be reasonable as of this date, but may be materially affected by many factors, as discussed below in our “Cautionary Statement Regarding Forward-Looking Statements” disclaimer. Actual results may vary from the outlook above and the variations may be material. The Company undertakes no intent or obligation to publicly update or revise any of these projections, whether as a result of new information, future events or otherwise, except as required by law.

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, gain on lease termination 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.
