CAUTIONARY STATEMENT CONCERNING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains certain statements that are “forward-looking” statements within the meaning of the federal securities laws and are presented pursuant to the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Such “forward-looking” statements include, but are not limited to, statements with respect to our future financial performance and condition, results of operations and business, our expectations or beliefs concerning future events, plans, objectives, expectations and intentions, and other statements that are not historical facts. These statements may contain words such as “believes,” “expects,” “may,” “will,” “should,” “would,” “could,” “seeks,” “approximately,” “intends,” “plans,” “estimates,” “projects,” “outlook,” “guidance,” “anticipates” or “looking forward” or similar expressions. In addition, we, through our senior management, from time to time make forward-looking public statements concerning our expected future operations and performance and other developments. These forward-looking statements are based upon the current beliefs and expectations of the management of Magnera and are subject to risks and uncertainties that may change at any time. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements. Although it is not possible to identify all of these risks and uncertainties, they include, among others, the following: global economic conditions; inflation; the cost and availability of raw materials and energy; disruption of our supply chain; the adverse impact of weather events on our facilities, inventory and suppliers, as well as adverse effects on our customers, suppliers and other business partners; the effect of competition on our business; our inability to integrate future acquired companies or to realize expected operating synergies; synergies expected to be achieved in connection with our business combination with a subsidiary of Berry Global Group, Inc.; our inability to retain our officers and employees or the occurrence of labor disputes; disruption of our information technology systems, including as a result of a cyber breach; risks associated with operating internationally, including fluctuating exchange rates, tariffs, differing tax laws and regulation; litigation and regulatory investigations; and disputes related to intellectual property used in our business. Additional information regarding these risks and uncertainties and other risks applicable to our business are described in additional detail in our reports filed with the Securities and Exchange Commission (the “SEC”), including our Annual Report on Form 10-K for the fiscal year ended September 27, 2025, and other filings that we make with the SEC. These risk factors may not contain all of the material factors that are important to you. New factors may emerge from time to time, and it is not possible to either predict new factors or assess the potential effect of any such new factors. Accordingly, readers should not place undue reliance on those statements. All forward-looking statements are made as of the date hereof, and we undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.
