Forward-looking statements

This report contains forward-looking statements, that is, information related to future, not past, events. Such statements generally include the words “believes,” “plans,” “intends,” "targets," “will,” “expects,” “suggests,” “anticipates,” “outlook,” “continues,” or similar expressions. Forward-looking statements include, without limitation, expected financial positions; results of operations; cash flows; financing plans; business strategy; operating plans; capital and other expenditures; competitive positions; growth opportunities for existing products; benefits from new technology and cost reduction initiatives, plans and objectives; succession planning, and markets for securities. For these statements, the Company claims the protections of the safe harbor for forward-looking statements contained in Section 27A of the Securities Act and Section 21E of the Exchange Act. Like other businesses, the Company is subject to risks and uncertainties that could cause its actual results to differ materially from its projections or that could cause other forward-looking statements to prove incorrect. Factors that

could cause actual results to differ materially from those contained in the forward-looking statements include, without limitation: risks related to foreign operations, especially in emerging regions; the effects of international trade disputes, tariffs and sanctions; the costs and availability of raw materials, energy and transportation; the effectiveness of its research and development and growth investments; acquisitions and divestitures of assets and businesses; developments affecting the Company’s outstanding indebtedness; developments affecting the Company’s pension obligations; its legal and environmental proceedings; environmental compliance costs; the inability to establish or maintain certain business relationships; the inability to hire or retain key personnel; natural disasters such as storms and floods, and force majeure events; changes in tax laws and regulations; the potential effects of cyberattacks; and those additional factors set forth in the Company’s most recent Annual Report on Form 10-K, quarterly reports on Form 10-Q, and current reports on Form 8-K, which have been filed with the Securities and Exchange Commission and are readily available on the internet at Our reported results should not be considered as an indication of future performance. Readers are cautioned not to place undue reliance on the Company’s projections and forward-looking statements, which speak only as of the dates those projections and statements are made. The Company undertakes no obligation to release publicly any revision to the projections and forward-looking statements contained in this report, or to update them to reflect events or circumstances occurring after the date of this document.

Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
