Achieved positive gross margin of approximately 20%, for the first quarter 2025

LOS ANGELES, CA – May 14, 2025 – Xos, Inc. (NASDAQ: XOS) (“Xos” or the “Company”), a leading electric truck manufacturer and fleet services provider, today reported financial results for the first quarter ended March 31, 2025.

•Delivered 29 units and generated $5.9 million in revenue during the first quarter of 2025, compared to 62 units and $13.2 million in revenue in the first quarter of 2024. Although Xos only recognized revenue in the first quarter of 2025 for the delivery of 29 units, the Company shipped 60 units, which included an additional 31 stripped chassis to our upfitter during the period in support of our previously announced order from UPS for 193 vehicles, which we expect to be delivered to the customer and recognize revenue in subsequent quarters in 2025.

•Achieved a substantial reduction in operating expenses, cutting operating costs by $2.6 million, a 19.6% decrease compared to Q1 2024, reflecting strong operational discipline.

Xos began 2025 with continued momentum despite a seasonal slowdown in the first quarter, as fleets across the country initiated their procurement planning for the year ahead. Xos experienced a reduction in cash flow in the first quarter of 2025, primarily driven by a planned inventory buildup designed to facilitate fulfillment of current orders on hand later in the fiscal year. We expect our liquidity position to improve in the subsequent quarters as we deliver vehicles in support of UPS and other customer orders. Deliveries this quarter included customers such as Vestis Corporation and FedEx ISPs. Xos also continued to make meaningful progress on vehicle incentives. While federal tax credit uncertainty remains, incentives continue to be available at the state level through well-established programs in California, New York, and Texas, as well as new programs opening up in New Jersey and Washington.

Dakota Semler, Chief Executive Officer of Xos, commented, “While we saw the typical seasonal slowdown following a strong Q4, we still shipped 60 vehicles in Q1. We’re already seeing momentum pick up in Q2, with increased deliveries and improved cash flow performance expected. We’re energized by the demand we’re seeing and anticipate growth for the remainder of the year.”

Liana Pogosyan, Acting Chief Financial Officer of Xos, added, “We remain focused on seeking to drive revenue growth and strengthening our gross margin, even in the face of ongoing tariff headwinds. We’ve gained more clarity around our near-term tariff exposure and have mitigation strategies in place for the second half of the year. We’re also proactively planning for 2026 and beyond to minimize disruption from these external pressures. At the same time, we continue to be disciplined in managing our costs and are seeking to generate sustained positive free cash flow.”

Xos is a leading technology company, electric truck manufacturer, and fleet services provider for battery-electric fleets. Xos vehicles and fleet management software are purpose-built for medium- and heavy-duty commercial vehicles that travel on last-mile, back-to-base routes. The company leverages its proprietary technologies to provide commercial fleets with battery-electric vehicles that are easier to maintain and more cost-efficient on a total cost of ownership (TCO) basis than their internal combustion engine counterparts. For more information, please visit www.xostrucks.com.

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 and non-GAAP gross profit, 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.

Xos believes that the use of operating cash flow less CapEx (Free Cash Flow), non-GAAP operating loss and non-GAAP gross profit reflects additional means of 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 and non-GAAP gross profit 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 and non-GAAP gross profit 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.

This press release includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. These forward-looking statements include, but are not limited to, statements regarding projected financial and performance information; expectations and timing related to product deliveries and customer demand; sufficiency of existing cash reserves; customer acquisition and order metrics; ability to access additional capital and Xos’s long-term strategy and future growth.

Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this press release, including but not limited to: (i) Xos’s liquidity and access to capital when needed, including its ability to service its indebtedness; (ii) Xos’s ability to implement business plans, forecasts, and other expectations, and identify and realize additional opportunities; (iii) cost increases and delays in production due to supply chain shortages in the components needed for the production of Xos's vehicle chassis and battery system; (iv) Xos's ability to meet production milestones and fulfill backlog orders; (v) changes in the industries in which Xos operates; (vi) variations in operating performance across competitors; (vii) changes in laws and regulations affecting Xos's business, including changes to tax incentive policies; (viii) Xos's ability to implement its business plan or meet or exceed its financial projections; (ix) Xos's limited operating history; (x) Xos's ability to retain key personnel and hire additional personnel, particularly in light of current and potential labor shortages; (xi) the risk of downturns and a changing regulatory landscape in the highly competitive electric vehicle industry; (xii) macroeconomic and political conditions; and (xiii) the outcome of any legal proceedings that may be instituted against Xos.

All forward-looking statements included in this press release are expressly qualified in their entirety by, and you should carefully consider, the foregoing factors and the other risks and uncertainties described under the heading “Risk Factors” included in Xos's Annual Report on Form 10-K for the year ended December 31, 2024 filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 31, 2025 and Xos's other filings with the SEC, copies of which may be obtained by visiting Xos's Investors Relations website at https://www.xostrucks.com/sec-filings or the SEC's website at www.sec.gov.

Readers are cautioned not to put undue reliance on forward-looking statements, and Xos assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise.
