© Copyright Xos, Inc. 2023. All rights reserved. Forward-Looking Statements This presentation 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, expectations related to product deliveries and customer demand; expectations regarding regulatory changes; and Xos’ long-term strategy and future growth. These forward-looking statements may be identified by the words “believe,” “plan,” “project,” “potential,” “seem,” “seek,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “target,” “opportunity,” “plan,” “may,” “could,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions and any other statements that predict or indicate future events or trends or that are not statements of historical matters, although not all forward-looking statements contain such identifying words. 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’ ability to implement business plans, forecasts, and other expectations, and identify and realize additional opportunities, (ii) Xos’ limited operating history, (iii) cost increases and delays in production due to supply chain shortages in the components needed for the production of Xos’ vehicle chassis and battery system, (iv) Xos’ 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’ business, (viii) Xos’ ability to implement its business plan or meet or exceed its financial projections (ix) Xos’ ability to retain key personnel and hire additional personnel, particularly in light of current and potential labor shortages, (x) the risk of downturns and a changing regulatory landscape in the highly competitive electric vehicle industry, (xi) Xos’ ability to service its indebtedness and (xii) 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’ Annual Report on Form 10-K for the year ended December 31, 2022 filed with the SEC on March 31, 2023 and Xos’ other filings with the SEC, copies of which may be obtained by visiting Xos’ Investors Relations website at https://investors.xostrucks.com/ or the SEC's website at www.sec.gov. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. 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. Xos does not give any assurance that it will achieve its expectations. Non-GAAP Financial Measures The financial information in this presentation has been presented in accordance with United States generally accepted accounting principles (“GAAP”) as well as on a non-GAAP basis to supplement our consolidated financial results. Our non-GAAP financial measures include Operating Cash Flow less CapEx (Free Cash Flow), Non-GAAP Operating Loss and Non-GAAP Gross Loss which are defined as follows. “Operating Cash Flow less CapEx (Free Cash Flow)” is defined as net cash 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 Loss” is defined as gross loss minus inventory write-downs and physical inventory and other adjustments. We believe that the use of Operating Cash Flow less CapEx (Free Cash Flow), Non-GAAP Operating Loss and Non-GAAP Gross Loss reflect additional means of evaluating Xos’ ongoing operating results and trends. Our presentation of these measures should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items. It is important to note our computation of Operating Cash Flow less CapEx (Free Cash Flow), Non-GAAP Operating Loss and Non-GAAP Gross Loss 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 Loss 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 our operating performance. A reconciliation between historical GAAP and non-GAAP financial information is provided in this presentation. Trademarks This presentation contains trademarks, service marks, trade names and copyrights of Xos and other companies, which are the property of their respective owners. The use or display of third parties’ trademarks, service marks, trade names or products in this presentation is not intended to, and does not imply, a relationship with Xos, or an endorsement or sponsorship by or Xos.
