Corporate Governance & Stewardship Fall 2026 Exhibit 99.1

Forward Looking Statements Cautionary Statement Regarding Forward-looking Statements Any statements of the Company’s expectations in these slides, including, but not limited to, statements regarding 2026 cost savings and capital spending constitute “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. Such statements are based on currently available operating, financial and competitive information and are subject to various risks and uncertainties that could cause actual results to differ materially from the Company’s historical experience and its present expectations. These risks and uncertainties include, but are not limited to, inflation of and volatility in raw material and energy costs, changes in consumer buying habits and product preferences, competition with other paperboard manufacturers and product substitution, the Company’s ability to implement its business strategies, including strategic acquisitions, productivity initiatives, cost reduction plans and integration activities, as well as the Company’s debt level, currency movements and other risks of conducting business internationally, the impact of regulatory and litigation matters, including the continued availability of the Company's U.S. federal income tax attributes to offset U.S. federal income taxes and the timing related to the Company’s future U.S. federal income tax payments. Undue reliance should not be placed on such forward-looking statements, as such statements speak only as of the date on which they are made and the Company undertakes no obligation to update such statements, except as may be required by law. Additional information regarding these and other risks is contained in the Company’s periodic filings with the Securities and Exchange Commission. Non-GAAP Financial Measures & Reconciliations This presentation includes certain historic financial measures that exclude or adjust for charges or income associated with business combinations, facility shutdowns, extended paperboard manufacturing facility outages, sales of assets and other special charges or income (“Non-GAAP Financial Measures”). The Company’s management believes that the presentation of these Non-GAAP Financial Measures provides useful information to investors because these measures are regularly used by management in assessing the Company’s performance. These Non-GAAP Financial Measures are not calculated in accordance with generally accepted accounting principles in the United States (“GAAP”) and 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 measures in the same manner as we do. A reconciliation of these Non-GAAP Financial Measures to the most relevant GAAP measure can be found in the Company’s earnings press releases. Note that a reconciliation of Non-GAAP Financial Measures provided as future performance guidance to the most relevant GAAP measure is not provided, as the Company is unable to reasonably estimate the timing or financial impact of items such as charges associated with business combinations and other special charges. The inability to estimate these future items makes a detailed reconciliation of these forward-looking non-GAAP financial measures impracticable. 2
