Cautionary Note Regarding Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking statements” within the meaning of Section 21E of the Exchange Act, and the Private Securities Litigation Reform Act of 1995, as amended. All statements other than statements of historical fact included or incorporated by reference in this Current Report on Form 8-K, including, among other things, statements regarding the proposed Merger and other transactions described herein, future events, plans and anticipated results of operations, business strategies, the anticipated benefits of the proposed transactions, the anticipated impact of the proposed transaction on the combined company’s business and future financial and operating results, the expected amount and timing of synergies from the proposed transaction, the anticipated closing date for the proposed transaction and other aspects of either company’s operations or operating results are forward-looking statements. Some of these statements may be identified by the use of the words “plans”, “expects” or “does not expect”, “estimated”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”, “intends”, “anticipates” or “does not anticipate”, “targets”, “projects”, “contemplates”, “predicts”, “potential”, “continue”, or “believes”, or variations of such words and phrases or state that certain actions, events or results “may”, “could”, “would”, “should”, “might”, “will” or “will be taken”, “occur” or “be achieved”.

Forward-looking statements are based on the opinions and estimates of management of Workhorse as of the date such statements are made, and they are subject to known and unknown risks, uncertainties, assumptions and other factors that may cause the actual results, level of activity, performance or achievements to be materially different from those expressed or implied by such forward-looking statements. These risks and uncertainties could give rise to a delay in or the failure to consummate the Merger or the other transactions described herein (collectively, the “Transactions”). Some factors that could cause actual results to differ include the outcome of continuing discussions between the Workhorse and Motiv with respect to the Transactions, including the possibility that the parties may terminate certain of the Transactions or that the terms of certain of the Transactions may change; our ability to consummate the Transactions or achieve the expected synergies and/or efficiencies; potential regulatory delays; the industry and market reaction to this announcement; the effect of the announcement of the Transactions on the ability of the parties to operate their businesses and retain and hire key personnel and to maintain favorable business relationships; the possibility that the integration of the parties may be more difficult, time-consuming or costly than expected or that operating costs and business disruptions may be greater than expected; the ability to obtain regulatory and other approvals required to consummate the Transactions, including from Nasdaq; the risk that the price of our securities may be volatile due to a variety of factors; changes in laws, regulations, technologies, the global supply chain, and macro-economic and social environments affecting our business; and our ability to maintain compliance with Nasdaq rules and otherwise maintain our listing of securities on Nasdaq.

Additional information on these and other factors that may cause actual results and Workhorse’s performance to differ materially is included in Workhorse’s periodic reports filed with the SEC, including, but not limited to, Workhorse’s Annual Report on Form 10-K for the year ended December 31, 2024, including those factors described under the heading “Risk Factors” therein, and Workhorse’s subsequent Quarterly Reports on Form 10-Q. Copies of Workhorse’s filings with the SEC are available publicly on the SEC’s website at www.sec.gov or may be obtained by contacting Workhorse. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. Readers are cautioned not to place undue reliance upon any forward-looking statements, which speak only as of the date made. These forward-looking statements are made only as of the date hereof, and Workhorse undertakes no obligations to update or revise the forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
