Forward-Looking Statements

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 and the Private Securities Litigation Reform Act of 1995. These forward-looking statements include our preliminary fourth-quarter 2024 revenue and adjusted EBITDA expectations. We base these preliminary expectations on current assumptions, which involve risks and uncertainties that could cause actual revenue and adjusted EBITDA results to differ materially including, among others, those risks and uncertainties included under the caption "Risk Factors" and elsewhere in our annual reports on Form 10-K and quarterly reports on Form 10-Q filed with the Securities and Exchange Commission. Furthermore, we are in the process of finalizing our fourth-quarter 2024 financial results and our final, audited results and final analysis of those results are not yet available. Therefore, the fourth-quarter 2024 revenue and adjusted EBITDA expectations are subject to further review and the actual results could differ from management’s expectations. Actual revenue and adjusted EBITDA are also subject to audit by our independent registered public accounting firm, with no assurance from our public accounting firm on the revenue and adjusted EBITDA expectations. You should not draw any conclusions from the fourth-quarter 2024 revenue and adjusted EBITDA expectations for any other financial results as of, and for the quarter ended, December 31, 2024. All information provided in this release and in the attachments is as of the date hereof, and we undertake no duty to update this information unless required by law.
