Forward-looking statements include, among other things, statements regarding the Company&#x2019;s intent to complete its analysis of the impact of the misclassification on its internal control over financial reporting and whether additional material weaknesses exist in its internal controls, its intent to restate its prior consolidated financial statements for the Non-Reliance Periods, the estimated impact of adjustments to the financial statements for the Non-Reliance Periods, the impact of the Company&#x2019;s material weakness or material weaknesses in internal control over financial reporting and the Company&#x2019;s disclosure controls and procedures on its financial statements and other public disclosures, the anticipated timing for filing the Company&#x2019;s 2023 Form 10-K and related matters. Forward-looking statements include statements that are not historical facts and can be identified by terms such as &#x201c;anticipate,&#x201d; &#x201c;believe,&#x201d; &#x201c;could,&#x201d; &#x201c;estimate,&#x201d; &#x201c;expect,&#x201d; &#x201c;intend,&#x201d; &#x201c;may,&#x201d; &#x201c;plan,&#x201d; &#x201c;potential,&#x201d; &#x201c;predict,&#x201d; &#x201c;project,&#x201d; &#x201c;seek,&#x201d; &#x201c;should,&#x201d; &#x201c;will,&#x201d; &#x201c;would&#x201d; or similar expressions and the negatives of those terms.
