Forward-Looking Statements

This communication includes statements that are forward-looking statements made pursuant to the safe harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements regarding the proposed acquisition (the “Merger”) of Kellanova (the “Company”) by Mars, Inc., stockholder and regulatory approvals, the expected timetable for completing the Merger, the excepted continued benefits to employees in light of the Merger, and any other statements regarding the Company’s future expectations, beliefs, plans, objectives, financial conditions, assumptions or future events or performance that are not historical facts. This information may involve risks and uncertainties that could cause actual results to differ materially from such forward-looking statements. These risks and uncertainties include, but are not limited to: failure to obtain the required vote of the Company’s stockholders in connection with the Merger; the timing to consummate the Merger and the risk that the Merger may not be completed at all or the occurrence of any event, change, or other circumstances that could give rise to the termination of the merger agreement, including circumstances requiring a party to pay the other party a termination fee pursuant to the merger agreement; the risk that the conditions to closing of the Merger may not be satisfied or waived; the risk that a governmental or regulatory approval that may be required for the Merger is not obtained or is obtained subject to conditions that are not anticipated; potential litigation relating to, or other unexpected costs resulting from, the Merger; legislative, regulatory, and economic developments; risks that the proposed transaction disrupts the Company’s current plans and operations; the risk that certain restrictions during the pendency of the proposed transaction may impact the Company’s ability to pursue certain business opportunities or strategic transactions; the diversion of management’s time on transaction-related issues; continued availability of capital and financing and rating agency actions; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the Company’s common stock, credit ratings or operating results; and the risk that the proposed transaction and its announcement could have an adverse effect on the ability to retain and hire key personnel, to retain customers and to maintain relationships with business partners, suppliers and customers. The Company can give no assurance that the conditions to the Merger will be satisfied, or that it will close within the anticipated time period.

All statements, other than statements of historical fact, should be considered forward-looking statements made in good faith by the Company, as applicable, and are intended to qualify for the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. When used in this communication, or any other documents, words such as “anticipate,” “believe,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “objective,” “plan,” “project,” “seek,” “strategy,” “target,” “will” and similar expressions are intended to identify forward-looking statements. These

forward-looking statements are based on the beliefs and assumptions of management at the time that these statements were prepared and are inherently uncertain. Such forward-looking statements are subject to risks and uncertainties that could cause the Company’s actual results to differ materially from those expressed or implied in the forward-looking statements. These risks and uncertainties, as well as other risks and uncertainties that could cause the actual results to differ materially from those expressed in the forward-looking statements, are described in greater detail under the heading “Item 1A. Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 30, 2023 filed with the United States Securities and Exchange Commission (the “SEC”) and in any other SEC filings made by the Company. The Company cautions that these risks and factors are not exclusive. Management cautions against putting undue reliance on forward-looking statements or projecting any future results based on such statements or present or prior earnings levels. Forward-looking statements speak only as of the date of this communication, and, except as required by applicable law, the Company does not undertake any obligation to update or supplement any forward-looking statements to reflect actual results, new information, future events, changes in its expectations or other circumstances that exist after the date as of which the forward-looking statements were made.
