Financial Results

LOS ANGELES, CA – March 28, 2022 – Xos, Inc. (NASDAQ: XOS), a leading manufacturer of fully electric Class 5 to Class 8 commercial vehicles, today reported its fourth quarter and full year 2021 financial results.

Key Financial and Business Highlights:

•Fourth quarter 2021 revenue was $3.3 million and $5.0 million for the full year ended December 31, 2021.

•Fourth quarter 2021 net income was $11.4 million and operating loss was $25.5 million, Non-GAAP operating loss for the quarter was $23.8 million.

•Deliveries to name brand customers, including UniFirst, FedEx Ground Operators, Thompson Truck Centers and Murphy-Hoffman Company, LLC ("MHC"), during fourth quarter 2021 and year-to-date 2022.

•Expanded distribution network through agreements with MHC and Yancey Bros. Co. (“Yancey”) during Q4 2021 and year-to-date 2022.

•Strengthened leadership team with addition of several industry veterans, including Scott Zion as Head of Engineering, Mike Chaffins as Vice President of Supply Chain, and Steve Ivsan as Head of Program Management.

•Cash and equivalents and investments of $168.7 million, including restricted cash of $3.0 million.

•Delivered 32 units to customers in Q4 2021, and 44 units for full-year 2021.

“We continue to make significant progress in all aspects of our business. We ramped production of our zero-emission vehicles and powertrains despite the continued global supply and logistics chain disruptions, brought to market innovative products, including our Lyra Battery series, and delivered for our customers across several high-growth, last-mile markets,” said Dakota Semler, Xos’ Chief Executive Officer.

“We remain one of the few companies to offer purpose-built fully electric mobility solutions tailored for the medium-duty commercial market with products in customers hands and on the road today. With the addition of our automated battery production line and further expansions planned in 2022, and as we continue to work through supply chain disruptions, we expect our manufacturing production rate to continue to accelerate. The caliber and depth of our committed team remains a key strength.”

Fourth Quarter 2021 Milestones and Accomplishments

Agreements with key customers and distributors participating in high-growth, last-mile markets, including:

•Multi-million-dollar truck order with Route Consultant, a premium broker for FedEx Ground contractors, to deliver 40 last-mile delivery vehicles in 2022.

•Strategic partnership with Yancey, the nation’s oldest Caterpillar dealer, to distribute Xos vehicles across the state of Georgia. The strategic partnership with Yancey allows Xos to leverage Yancey’s existing infrastructure and facilities, including dedicated truck service centers across the state of Georgia, and expands Xos’ robust dealership network.

•Strategic partnership with Merchants Fleet, the nation’s fastest growing fleet management company, to grow their EV portfolio for last mile delivery. Xos expects to deliver the first 10 step vans to Merchants Fleet in 2022.

•Purchase order with Southern Glazer’s Wine & Spirits to deliver 10 first-of-their-kind electric delivery trucks. This is the first major incorporation of EVs into Southern Glazer’s fleet, following the success of a recent pilot program with Xos.

Recent Business Updates

•Strategic dealership agreement with MHC - one of the largest dealership networks - to establish sales and service support for vehicles across six states.

•Delivered three vehicles to UniFirst Corporation in Southern California. This delivery was part of an initial rollout of vehicles purchased by the workwear and textile service company. Additional deliveries are expected to occur to UniFirst’s Massachusetts locations in 2022.

•Deliveries to FedEx Ground Operators, with additional deliveries expected in the first half of 2022.

•In March 2022 Xos executed a $125 Million Standby Equity Purchase Agreement (the “Yorkville Agreement”) with an affiliate of Yorkville Advisors Global, LP (the “Yorkville Fund”) - which at Xos’ sole discretion - provides Xos the right to issue and sell to the

Yorkville Fund up to $125 million of Xos’ common stock, subject to certain terms and conditions.

Made several key hires, bolstering the Company’s manufacturing and supply chain expertise, including:

•Scott Zion, as Xos’ Head of Engineering. Mr. Zion brings decades of engineering for manufacturing leading automotive manufacturers such as Hino, Navistar, and Ford.

•Mike Chaffins, as Xos’ Vice President of Supply Chain. Mr. Chaffins has 30 years of automotive supply chain experience, including at Nikola, Toyota, Mercedes-Benz, and Nissan.

•Steve Ivsan, as Xos’ Head of Program Management. Mr. Ivsan has nearly three decades of automotive experience at both legacy automakers, such as Chrysler and Continental Automotive, and electric vehicle companies, such as Tesla, Byton, Rivian and Outrider.

•Xos also welcomed Anousheh Ansari and Alice K. Jackson to its board of directors in December 2021, bringing valuable experience in energy infrastructure and innovative technologies. Ms. Ansari is Chief Executive Officer of XPRIZE Foundation, Inc. and co-founded Prodea Systems, Inc., which provides services and applications for in-home smart devices, networked appliances, and mobile lifestyle devices, and Telecom Technologies, Inc., which developed software for intelligent systems for the telecommunications market. She serves as director of Jabil Inc., and as chair of the board of directors of Sceye Inc. Ms. Jackson serves as President of the Colorado service area at Xcel Energy Inc., a major U.S. electricity and natural gas company. Ms. Jackson is also Chair of the board of the Smart Electric Power Alliance.

Financial Highlights and Business Outlook for First Quarter of 2022

Kingsley Afemikhe, Xos’ Chief Financial Officer, commented: “We closed out the year with expansion in vehicle deliveries above our outlook for the fourth quarter, despite dealing with the continued supply chain disruption leading to increased material and logistics costs. As we scale battery and vehicle manufacturing and continue to work through supply chain disruptions, we

expect to continue to deliver sequential quarterly growth in revenue and deliveries in 2022. Net cash used in operating activities and cash paid for capital expenditures totaled $37.3 million”.

He continued “Our existing cash reserves are sufficient for us to scale manufacturing, invest in R&D and build working capital. The $125 million Standby Equity Purchase Agreement we have signed with an affiliate of Yorkville Advisors Global provides increased financial flexibility. Any funding activity under this facility will be undertaken systematically and opportunistically as market conditions warrant and as we progress through 2022 and prepare for further growth-related cash requirements in 2023 and beyond.”

First Quarter 2022 Outlook

For the first quarter of 2022, the Company provides the following outlook:

•Deliveries to be in the range of 40 to 50 units,

•Revenues to be in the range of $4.5 to $6.3 million, and

•Non-GAAP operating loss in the range of $20 to $25 million.

The outlook provided above is based on management beliefs and expectations as of the date of this press release. This outlook assumes that no business acquisitions, investments, restructurings, or legal settlements are concluded in the quarter. 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 “Forward-Looking Statements.” 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’ consolidated financial results. Xos’ non-GAAP financial measures include Operating Cash Flow less CapEx (Free Cash Flow), Non-GAAP Operating Loss and Adjusted EBITDA which are defined below.

“Operating Cash Flow less CapEx (Free Cash Flow)” is defined as net cash used in operating activities minus purchase of property and equipment.

“Non-GAAP Operating Loss” is defined as operating loss adjusted for stock-based compensation.

“Adjusted EBITDA” is defined as net loss before other non-operating expense or income, income tax expense or benefit, and depreciation and amortization, adjusted for stock-based compensation and other non-recurring items determined by management.

Xos believes that the use of Operating Cash Flow less CapEx (Free Cash Flow), Non-GAAP Operating Loss and Adjusted EBITDA reflects additional means of evaluating Xos’ ongoing operating results and trends. The presentation of these measures should not be construed as an inference that Xos’ future results will be unaffected by unusual or non-recurring items. It is important to note Xos’ computation of Operating Cash Flow less CapEx (Free Cash Flow), Non-GAAP Operating Loss 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 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’ operating performance. A reconciliation between historical GAAP and non-GAAP financial information is provided in this press release.

This release includes forward-looking outlook for Non-GAAP Operating Loss. The Company is not able to provide, without unreasonable effort, a reconciliation of the outlook for Non-GAAP Operating Loss because the Company does not currently have sufficient data to accurately estimate the variables and individual adjustments included in the most directly comparable GAAP measure that would be necessary for such reconciliations, including (a) stock-based compensation, (b) total operating expenses and (c) other nonrecurring expenses that cannot reasonably be estimated in advance. These adjustments are inherently variable and uncertain and depend on various factors that are beyond Xos’ control and as a result Xos is also unable to predict their probable significance. Therefore, because management cannot estimate on a forward-looking basis without unreasonable effort the impact these variables and individual adjustments will have on its reported results in accordance with GAAP, it is unable to provide a reconciliation of the non-GAAP measures included in its outlook for the first quarter of 2022.
