Forward Looking Statements

The information in this press release includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of present or historical fact included in this press release regarding XL Fleet’s new product offerings, the proposed business combination, including Pivotal’s ability to consummate the transaction, the anticipated timing of the closing of the business combination and benefits of the transaction, and the combined company’s future financial performance, as well as the combined company’s strategy, future operations, estimated financial position, estimated revenues and losses, projected costs, prospects, plans and objectives of management, are forward-looking statements. Forward-looking statements are inherently subject to risks, uncertainties and assumptions. These statements may be preceded by, followed by or include the words “anticipates,” “believes,” “estimates,” “expects,” “projects,” “forecasts,” “may,” “will,” “should,” “seeks,” “plans,” “scheduled,” “anticipates” or “intends” or similar expressions. Such forward-looking statements involve risks and uncertainties that may cause actual events, results or performance to differ materially from those indicated by such statements. Certain of these risks are identified and discussed in Pivotal’s Annual Report on Form 10-K for the year ended December 31, 2019 under Risk Factors in Part I, Item 1A and in Pivotal’s Quarterly Reports on Form 10-Q for the quarters ended June 30, 2020 and September 30, 2020. These risk factors will be important to consider in determining future results and should be reviewed in their entirety. These forward-looking statements are expressed in good faith, and Pivotal and XL believe there is a reasonable basis for them. However, there can be no assurance that the events, results or trends identified in these forward-looking statements will occur or be achieved. Forward-looking statements speak only as of the date they are made, and neither Pivotal nor XL is under any obligation, and expressly disclaim any obligation, to update, alter or otherwise revise any forward-looking statement, whether as a result of new information, future events or otherwise, except as required by law. Readers should carefully review the statements set forth in the reports, which Pivotal has filed or will file from time to time with the SEC.

In addition to factors previously disclosed in Pivotal’s reports filed with the SEC and those identified elsewhere in this communication, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: the parties’ ability to meet the closing conditions to the merger, including approval by stockholders of Pivotal and XL on the expected terms and schedule and the risk that regulatory approvals required for the merger are not obtained or are obtained subject to conditions that are not anticipated; delay in closing the merger or the PIPE Offering; failure to realize the benefits expected from the proposed transaction; the effects of pending and future legislation; risks related to disruption of management time from ongoing business operations due to the proposed transaction; business disruption following the transaction; other consequences associated with mergers, acquisitions and divestitures and legislative and regulatory actions and reforms; risks associated with XL’s business, including the highly competitive nature of XL’s business and the market for hybrid electric vehicles; litigation, complaints, product liability claims and/or adverse publicity; cost increases or shortages in the components necessary to support XL’s products and services; the introduction of new technologies; privacy and data protection laws, privacy or data breaches, or the loss of data; and the impact of the COVID-19 pandemic on XL’s business, results of operations, financial condition, regulatory compliance and customer experience.

Any financial projections in this communication are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond Pivotal’s and XL’s control. While all projections are necessarily speculative, Pivotal and XL believe that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection extends from the date of preparation. The assumptions and estimates underlying the projected results are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. The inclusion of projections in this communication should not be regarded as an indication that Pivotal and XL, or their respective representatives and advisors, considered or consider the projections to be a reliable prediction of future events.

This communication is not intended to be all-inclusive or to contain all the information that a person may desire in considering in an investment in Pivotal and is not intended to form the basis of an investment decision in Pivotal. All subsequent written and oral forward-looking statements concerning Pivotal and XL, the proposed transactions or other matters and attributable to Pivotal and XL or any person acting on their behalf are expressly qualified in their entirety by the cautionary statements above.
