Forward-looking statements and other important legal information This report and the materials or websites cross-referenced contain statements that are aspirational or re昀氀ective of our views about our future performance that constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are generally identi昀椀ed through the inclusion of words such as “aim,” “anticipate,” “aspire,” “believe,” commit,” “endeavor,” “estimate,” “expect,” “goal,” “intend,” “may,” “plan,” “seek,” “strive,” “target,” “projection,” “will,” and “work,” or similar statements or variations of such terms and other similar expressions. The forward-looking statements in this document and the materials or websites cross- referenced concern our goals, progress or expectations with respect to corporate responsibility, sustainability, employees, environmental matters, policy, and business risks and opportunities. Forward-looking statements inherently involve risks and uncertainties that could cause actual results to di昀昀er materially from those predicted in such statements. These statements are based on numerous assumptions that we believe are reasonable, but are open to a wide range of uncertainties and business risks. In addition, these statements may be based on standards for measuring progress that are still developing, controls and processes that continue to evolve, and assumptions that are subject to change in the future. Consequently, actual results may vary materially from what is contained in a forward-looking statement. For a further description of the risks and uncertainties that could cause actual results to di昀昀er from those expressed in these forward-looking statements, as well as risks relating to our business in general, see our Annual Report on Form 10-K 昀椀led with the Securities and Exchange Commission (SEC) on February 9, 2024 and our subsequent periodic reports 昀椀led with the SEC from time to time. Copies of these 昀椀lings are available on the Enphase website at http://investor.enphase.com/sec.cfm, or on the SEC website at www.sec.gov. All forward-looking statements in this report are based on information currently available to us, and we assume no obligation to update these forward-looking statements in light of new information or future events. The information included in, and any issues identi昀椀ed as material for purposes of, this document may not be considered material for SEC reporting purposes. In the context of this report, the term “material” is distinct from, and should not be confused with, such term as de昀椀ned for SEC reporting purposes.
