Such statements are based on management's current expectations and are subject to a number of risks and uncertainties that could cause actual results to differ materially from those described therein. Forward-looking statements include references to the Company&#x2019;s expectations with respect to future revenue, growth, free cash flow, financial outlook, profitability, differentiated product portfolio and the ability to self-fund growth and drive demand. The important factors that could cause actual results to differ significantly from those expressed or implied by such forward-looking statements include, but are not limited to: failure to achieve acceptance of the Company&#x2019;s products by the surgeon community and changes to our financial results for the quarter and year ended December 31, 2024 due to the completion of financial closing procedures. The words &#x201c;believe,&#x201d; &#x201c;will,&#x201d; &#x201c;should,&#x201d; &#x201c;expect,&#x201d; &#x201c;intend,&#x201d; &#x201c;estimate,&#x201d; &#x201c;look forward&#x201d; and &#x201c;anticipate,&#x201d; and variations of such words and similar expressions identify forward-looking statements, but their absence does not mean that a statement is not a forward-looking statement. A further list and description of these and other factors, risks and uncertainties can be found in the Company's most recent annual report, and any subsequent quarterly and current reports, filed with the Securities and Exchange Commission. ATEC disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise, unless required by law.</font></p>
