**Item 2.02.** &nbsp;&nbsp;&nbsp;&nbsp;**Results of Operations and Financial Condition.**

On April 28, 2026, Clearwater Paper Corporation (the "Company") announced its results of operations and financial condition for the first quarter ending March 31, 2026. A copy of the press release containing this announcement is furnished as Exhibit 99.1 hereto. In addition, a copy of the Company's First 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 net income (loss) from continuing operations is calculated by excluding from net income, goodwill impairment charges, other operating credits and charges, net, income (loss) from discontinued operations, net of tax and adjusts for a normalized tax rate. Adjusted EBITDA from continuing operations and adjusted net income (loss) 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 Company believes that adjusted net income (loss) from continuing operations, which excludes goodwill impairment charges, income (loss) from discontinued operations, net of tax and other operating credits and charges, net, adjusted for a normalized tax rate is a useful measure for evaluating our ability to generate earnings and that providing this measure will allow investors to more readily compare the earnings referred to in the press release to the Company's earnings for past and future periods. The Company believes that this measure is particularly useful where the amounts of the excluded items are not consistent between the periods presented. It should be noted that other companies may present 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 net income has material limitations as a performance measure because it excludes items that are actually incurred or experienced in connection with the operations of the Company's 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.

**Exhibit 99.1**

**Clearwater Paper Reports First Quarter 2026 Results**

SPOKANE, Wash.--(BUSINESS WIRE)--April 28, 2026 --**Clearwater Paper Corporation (NYSE:CLW)**, a premier independent supplier of bleached paperboard to North American converters today reported financial results for the first quarter ended March 31, 2026.

FIRST QUARTER HIGHLIGHTS

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net sales of $360 million versus $378 million in the first quarter of 2025, with volume up 5%, offset by lower market pricing

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net loss of $13 million, or $0.80 per diluted share versus net loss of $6 million, or $0.38 per diluted share in the first quarter of 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EBITDA from continuing operations of $2 million versus $30 million in the first quarter of 2025 primarily due to lower market pricing and severe weather impacts

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Launched Velora<sup>TM</sup> a new lightweight folding carton paperboard engineered to deliver dependable performance, higher yield and strong value for everyday packaging

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Announced restructuring of Cypress Bend, Arkansas facility in April, resulting in reduction of approximately 20% of roles and expected annual savings of $8 to $12 million

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Received $17 million in additional representation and warranty insurance proceeds, pursuing claims against $50 million of remaining policy limit

"We delivered solid operational execution during the first quarter, with our team doing an outstanding job managing through a severe weather event in the Southeast. We also delivered healthy volume growth that outpaced the market even as we navigated a challenging industry environment," said Arsen Kitch, president and chief executive officer.

OVERALL RESULTS

For the first quarter of 2026, Clearwater Paper reported net sales of $360 million, compared to $378 million in the first quarter of 2025. The company reported a net loss from continuing operations of $13 million, or $0.80 per diluted share for the quarter, compared to a net loss of $6 million, or $0.36 per diluted share, in the prior-year period. Adjusted EBITDA from continuing operations was $2 million for the first quarter of 2026 compared to $30 million in the first quarter of 2025.

The increase in net loss was primarily driven by lower pricing and the impact of a weather event during the first quarter of 2026, partially offset by insurance proceeds and cost reductions. The decrease in Adjusted EBITDA primarily reflects lower pricing and weather-related impacts, partially offset by reduced costs.

Sales volumes and prices:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Sales volumes were 302,918 tons in the first quarter of 2026, an increase of 5% compared to 289,487 tons in the first quarter of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Paperboard average net selling price decreased 7% to $1,101 per ton for the first quarter of 2026, compared to $1,188 per ton in the first quarter of 2025.

COMPANY OUTLOOK

"We are focused on items within our control, namely reducing costs and maintaining share with our strategic customers, while anticipating an improvement in industry conditions. Today's operating rates and recent increases in input costs are resulting in margins and cash flows that do not support long-term investments in our industry's capital-intensive assets. We believe that a combination of demand growth, lower imports, and changes in net domestic supply will drive a recovery in the medium term," concluded Kitch.

WEBCAST INFORMATION

Clearwater Paper Corporation will discuss these results during an earnings conference call that begins at 2:00 p.m. Pacific Time on April 28, 2026. A live webcast and accompanying supplemental information will be available on the company's website. A replay of the conference call will be available on the website beginning at 5:00 p.m. Pacific Time the same day.

USE OF NON-GAAP MEASURES

In this press release, the company presents certain non-GAAP financial information for the first quarter of 2026 and 2025, including adjusted net income (loss) from continuing operations and Adjusted EBITDA from continuing operations. Because these amounts are not in accordance with GAAP, reconciliations to net income (loss) from continuing operations and Adjusted EBITDA from continuing operations as determined in accordance with GAAP are included in the tables at the end of this press release. The company presents these non-GAAP metrics because management believes they assist investors and analysts in comparing the company's performance across reporting periods on a consistent basis by excluding items that the company does not believe are indicative of its core operating performance. In addition, the company uses Adjusted EBITDA from continuing operations: (i) as a factor in evaluating management's performance when determining incentive compensation, (ii) to evaluate the effectiveness of the company's business strategies, and (iii) because the company's credit agreement and the indentures governing the company's outstanding notes use metrics similar to Adjusted EBITDA from continuing operations to measure the company's compliance with certain covenants. Non-GAAP measures may differ from similarly titled measures of other companies.

This press release contains certain "forward-looking" statements within the meaning of Section 27A of Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended by the Private Securities Litigation Reform Act of 1995 as amended, including statements regarding the company's expectations about the outlook for the next quarter, industry supply and demand conditions, pricing trends, market recovery timing, operating performance, cost reduction initiatives, restructuring outcomes, insurance recoveries, operational execution, import conditions, market share, and the company's ability to execute its strategy and strengthen customer relationships amid current market conditions.

2 Forward Looking Statements Cautionary Statement Regarding Forward Looking Statements This presentation of supplemental information contains, in addition to historical information, certain "forward-looking" statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended by the Private Securities Litigation Reform Act of 1995 as amended, including statements as to: our expectations regarding additional savings from our fixed cost reduction initiatives; the Company's strategic positioning to capitalize on the paperboard industry's cyclical nature and deliver strong returns; product demand and industry trends; assumptions for Q2 2026 and full year 2026, including operational factors, capital, input costs, lower pricing and inflation; our capital allocation priorities; our strategy, including achieving target leverage ratio and maintaining liquidity; our focus on free cash flow generation through operational efficiencies and demand; our plans to explore avenues for strategic growth opportunities, particularly to expand our own product offerings and broaden such offerings to North American customers; continued investments into our assets to strengthen our competitive advantages and maintain our long-term performance; expectations regarding the paperboard market; targeted working capital improvements; and our financial flexibility and liquidity; and repurchases under the existing share buyback authorization. These forward-looking statements are based on management's current expectations, estimates, assumptions and projections that are subject to change. Our actual results of operations may differ materially from those expressed or implied by the forward-looking statements contained in this presentation. Important factors that could cause or contribute to such differences include the risks and uncertainties described from time to time in the Company's public filings with the Securities and Exchange Commission, including but not limited to the following: our inability to realize the expected benefits of the Augusta, Georgia paperboard manufacturing facility acquisition, including anticipated financial results, due to integration challenges or other factors; unexpected costs, charges or expenses resulting from the sale of our consumer products division (tissue business) and the related restructuring initiatives; competitive pricing pressures for our products arising from capacity additions, demand reduction and market conditions; the loss of, changes in prices for, or reduction in, orders from significant customers; changes in customer preferences, industry consolidation and vertical integration; changes in the cost and availability of wood fiber, pulp, energy, chemicals, packaging and transportation services; cyclical industry conditions and broader U.S. and global economic conditions; manufacturing or operating disruptions; labor disruptions; reliance on a limited number of suppliers and service providers; cyber-security risks; environmental liabilities and litigation, including PFAS-related claims involving our Augusta facility; our ability to execute our growth, expansion and operational efficiency initiatives and capital projects; changes in expenses, required contributions or withdrawal costs associated with our pension plans; our ability to attract and retain qualified personnel; our ability to service our debt obligations and comply with debt covenants; changes in banking relationships or credit ratings; and changes in laws, regulations or industry standards affecting our business. Forward-looking statements contained in this presentation present management's views only as of the date of this presentation. We undertake no obligation to publicly update forward-looking statements or to retract future revisions of management's views based on events or circumstances occurring after the date of this presentation. Non-GAAP Financial Measures This presentation includes certain financial measures that are not calculated in accordance with GAAP, including Adjusted EBITDA from continuing operations. The Company's management believes that the presentation of these financial measures provides useful information to investors because these measures are regularly used by management in assessing the Company's performance. These financial measures should be considered in addition to results prepared in accordance with GAAP but should not be considered substitutes for or superior to GAAP results. In addition, these non-GAAP financial measures may not be comparable to similarly-titled measures utilized by other companies, since such other companies may not calculate such measure in the same manner as we do. A reconciliation of Adjusted EBITDA to the most relevant GAAP measure is available in the appendix of this presentation.

As there is uncertainty in connection with calculating the adjustments necessary to prepare reconciliations from Adjusted EBITDA to the comparable GAAP financial measure, the Company is unable to reconcile the Adjusted EBITDA projections without unreasonable efforts. Therefore, no reconciliation is being provided at this time. These items could result in significant adjustments from the most comparable GAAP measure.
