Cautionary Statement Regarding Forward-Looking Statements

These definitive additional proxy materials contain certain “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995, 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 historical fact contained in these definitive additional proxy materials, including statements as to the transactions contemplated by the business combination and related agreements, future results of operations and financial position, revenue and other metrics, planned products and services, business strategy and plans, objectives of management for future operations of Dragonfly Energy Corp. (“Dragonfly”), market size and growth opportunities, competitive position and technological and market trends, are forward-looking statements. Some of these forward-looking statements can be identified by the use of forward-looking words, including “may,” “should,” “expect,” “intend,” “will,” “estimate,” “anticipate,” “believe,” “predict,” “plan,” “targets,” “projects,” “could,” “would,” “continue,” “forecast” or the negatives of these terms or variations of them or similar expressions. All forward-looking statements are subject to risks, uncertainties, and other factors (some of which are beyond the control of Chardan) which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. All forward-looking statements are based upon estimates, forecasts and assumptions that, while considered reasonable by Chardan and its management, are inherently uncertain and many factors may cause the actual results to differ materially from current expectations which include, but are not limited to: 1) the outcome of any legal proceedings that may be instituted against Chardan; 2) other risks and uncertainties set forth in the sections entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in Chardan’s Definitive Proxy Statement (File No. 001-40730), as filed on July 22, 2022. The Definitive Proxy Statement addresses other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Nothing in these definitive additional proxy materials should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. Chardan does not give any assurance that either Chardan or Dragonfly or the combined company will achieve its expected results. Chardan undertakes no duty to update these forward-looking statements, except as otherwise required by law.

No Offer or Solicitation

These definitive additional proxy materials are and the information contained herein are not intended to and do not constitute an offer to sell or the solicitation of an offer to buy, sell or solicit any securities or any proxy, vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be deemed to be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act or an exemption therefrom.
