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' condensed consolidated financial results. Xos' non-GAAP financial measures include operating cash flow less CapEx (Free Cash Flow), non-GAAP operating loss and non-GAAP gross profit (loss), which are defined below.

"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 profit (loss)" 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 (loss) 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 non-GAAP gross profit (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 profit (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 Xos' operating performance. A reconciliation between historical GAAP and non-GAAP financial information is provided in this press release.

This release includes a 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 2024.
