Item 2.02. Results of Operations and Financial Condition.
On July 29, 2025, Clearwater Paper Corporation (the “Company”) announced its results of operations and financial condition for the second quarter ending June 30, 2025. A copy of the press release containing this announcement is furnished as Exhibit 99.1 hereto. In addition, a copy of the Company’s Second Quarter Supplemental Information is furnished as Exhibit 99.2 hereto.
In addition to disclosing financial results calculated in accordance with U.S. generally accepted accounting principles (“GAAP”), the following are disclosed in the attached Adjusted EBITDA from continuing operations, which is defined as earnings before interest expense, taxes, depreciation and amortization, other operating credits and charges, net and other non-operating items from continuing operations. Adjusted EBITDA from continuing operations are not a substitute for the GAAP measure of net income or other GAAP measures of operating performance.
The Company discloses Adjusted EBITDA in the attached because it is used as an important supplemental measure of its performance and believes that similarly-titled measures are frequently used by securities analysts, investors and other interested persons in the evaluation of companies in its industry, some of which present similarly-titled measures when reporting their results. The Company uses Adjusted EBITDA to evaluate its performance as compared to other companies in its industry that have different financing and capital structures and/or tax rates. It should be noted that companies calculate similarly-titled measures differently and, therefore, as presented by the Company may not be comparable to similarly-titled measures reported by other companies. In addition, Adjusted EBITDA has material limitations as a performance measure because it excludes interest expense, income tax expense and depreciation and amortization which are necessary to operate the Company's business or which the Company otherwise incurred or experienced in connection with the operation of its business.
The information in Item 2.02, including Exhibits 99.1 and 99.2 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
