CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report on Form 10-K contains 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 (the “Exchange Act”), which reflect our current views with respect to, among other things, our operations and financial performance. You can identify these forward-looking statements by the use of words such as “outlook,” “believe,” “expect,” “potential,” “continue,” “may,” “should,” “seek,” “approximately,” “predict,” “intend,” “will,” “plan,” “estimate,” “anticipate,” the negative version of these words, other comparable words or other statements that do not relate strictly to historical or factual matters. By their nature, forward-looking statements speak only as of the date they are made, are not statements of historical fact or guarantees of future performance and are subject to risks, uncertainties, assumptions or changes in circumstances that are difficult to predict or quantify. Our expectations, beliefs and projections are expressed in good faith and we believe there is a reasonable basis for them. However, there can be no assurance that management’s expectations, beliefs and projections will result or be achieved and actual results may vary materially from what is expressed in or indicated by the forward-looking statements.

There are many factors that may cause our actual results to differ materially from the forward-looking statements, including factors set forth under Part I, Item 1A. "Risk Factors" and Part I, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations" in this Form 10-K, as such factors may be updated from time to time in our other periodic filings with the SEC, which are accessible on the SEC's website at www.sec.gov and on the investor relations section of our website at www.ceaindustries.com. You should evaluate all forward-looking statements made in this Form 10-K in the context of these risks and uncertainties.

We caution you that the risks, uncertainties and other factors referenced below may not contain all of the risks, uncertainties and other factors that are important to you. In addition, we cannot assure you that we will realize the results, benefits or developments that we expect or anticipate or, even if substantially realized, that they will result in the consequences or affect us or our business in the way expected. All forward-looking statements in this Form 10-K apply only as of the date made and are expressly qualified in their entirety by the cautionary statements included in this Form 10-K and in other filings we make with the SEC. We undertake no obligation to publicly update or revise any forward-looking statements to reflect subsequent events or circumstances, except as required by law.

Except where the context requires otherwise, the terms "Company," "we," "us," "our" and "BNC" refer to CEA Industries Inc., a Nevada corporation, and its subsidiaries.
