Cautionary Statement Regarding Forward Looking Statements

This Form 6-K may contain forward-looking statements within the meaning of the securities laws of certain jurisdictions, including ‘forward-looking statements’ within the meaning of the United States Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. Words and terminology such as ‘will’, ‘aim’, ‘expects’, ‘anticipates’, ‘intends’, ‘looks’, ‘believes’, ‘vision’, ‘ambition’, ‘target’, ‘goal’, ‘plan’, ‘potential’, ‘work towards’, ‘may’, ‘milestone’, ‘objectives’, ‘outlook’, ‘probably’, ‘project’, ‘risk’, ‘continue’, ‘should’, ‘would be’, ‘seeks’, or the negative of these terms and other similar expressions of future performance, results, actions or events, and their negatives, are intended to identify such forward-looking statements. Forward-looking statements also include, but are not limited to, statements and information regarding the pending transaction of Unilever Foods with McCormick. Forward-looking statements can be made in writing but also may be made verbally by directors, officers and employees of the Unilever Group.

These forward-looking statements are based upon current expectations and assumptions regarding anticipated developments and other factors affecting the Unilever Group. They are not historical facts, nor are they guarantees of future performance or outcomes. All forward-looking statements contained in this Form 6-K are expressly qualified in their entirety by the cautionary statements contained in this section. Readers should not place undue reliance on forward-looking statements. Because these forward-looking statements involve known and unknown risks and uncertainties, a number of which may be beyond the Unilever Group’s control, there are important factors that could cause actual results to differ materially from those expressed or implied by these forward-looking statements. Among other risks and uncertainties, the material or principal factors which could cause actual results to differ materially from the forward-looking statements expressed in this Form 6-K are: the parties’ ability to meet expectations regarding the timing, completion and accounting and tax treatments of the transaction, including changes in relevant tax and other applicable laws, and the occurrence of any event, change or other circumstance that could give rise to the termination of the transaction agreement, the failure to obtain necessary regulatory approvals, approval of McCormick shareholders, anticipated tax treatment or any required financing, or to satisfy any of the other conditions to the transaction, including the risks that a governmental entity may prohibit, delay or refuse to grant approval for the consummation of the transaction, may require conditions, limitations or restrictions in connection with such approvals or that such regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the transaction; the risk that the proposed transaction may not be completed on the terms or in the time frame expected by the parties, or at all; direct transaction costs and substantial transition and integration-related costs associated with the proposed transaction with Unilever Foods; the possibility that unforeseen liabilities, future capital expenditures, revenues, expenses, charges, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies resulting from the transaction or otherwise could adversely impact anticipated combined company metrics and/or the value or expected benefit of, timing or pursuit of the transaction, the risk that the anticipated ownership percentages of McCormick shareholders, Unilever shareholders and Unilever following the closing of the transaction may differ from those expected, the risks and costs of the pursuit and/or implementation of the anticipated separation of Unilever Foods’ business, including the anticipated timing required to complete the separation, any adjustment to the terms of the transaction and any changes to the configuration of the businesses included in the separation if implemented, uncertainties as to McCormick’s access to available financing to consummate the transaction upon acceptable terms and on a timely basis or at all, the failure to obtain the effectiveness of the registration statements for the transaction or receipt of McCormick shareholder approval for the transaction and certain related matters, the effect of the announcement or pendency of the transaction on Unilever Foods’ or McCormick’s business relationships, competition, business, financial condition and operating results, including risks that the transaction disrupts current plans and operations of Unilever Foods or McCormick, the ability of Unilever Foods or McCormick to retain and hire key personnel, risks related to diverting either management team’s attention from ongoing business operations, and risks associated with third-party contracts containing consent and/or other provisions that may be triggered by the transaction; the ability of McCormick to successfully integrate Unilever Foods’ operations and implement its plans, forecasts and other expectations with respect to Unilever Foods’ business or the combined business after the closing of the transaction; the ability of McCormick to manage additional debt and successfully de-lever following the transaction; the outcome of any legal proceedings that may be instituted against Unilever Foods or McCormick related to the transaction; Unilever' ability to innovate and remain competitive; Unilever' investment choices in its portfolio management; the effect of climate change on Unilever' business; Unilever' ability to find sustainable solutions to its plastic packaging; significant changes or deterioration in customer relationships; the recruitment and retention of talented employees; disruptions in Unilever' supply chain and distribution; increases or volatility in the cost of raw materials and commodities; the production of safe and high-quality products; secure and reliable IT infrastructure; execution of acquisitions, divestitures and business transformation projects; economic, social and political risks and natural disasters; financial

risks; failure to meet high and ethical standards; and managing regulatory, tax and legal matters and practices with regard to the interpretation and application thereof and emerging and developing ESG reporting standards including differences in implementation of climate and sustainability policies in the regions where the Unilever Group operates. Risk with respect to McCormick are further described in its filings with the US Securities and Exchange Commission (“SEC”), including McCormick’s Annual Report on Form 10-K for the year ended November 30, 2025 and Quarterly Report on Form 10-Q for the quarter ended February 28, 2026. The forward-looking statements are based on our beliefs, assumptions and expectations of our future performance, taking into account all information currently available to us. Forward-looking statements are not predictions of future events. These beliefs, assumptions and expectations can change as a result of many possible events or factors, not all of which are known to us. If a change occurs, our business, financial condition, liquidity and results of operations may vary materially from those expressed in our forward-looking statements.

The forward-looking statements speak only as of the date of this Form 6-K. Except as required by any applicable law or regulation, the Unilever Group expressly disclaims any intention, obligation or undertaking to release publicly any updates or revisions to any forward-looking statements contained herein to reflect any change in the Unilever Group’s expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based. New risks and uncertainties arise over time, and it is not possible for us to predict those events or how they may affect us. In addition, we cannot assess the impact of each factor on our business or the extent to which any factor, or combination of factors, may cause actual events, to differ materially from those contained in any forward-looking statements. Further details of potential risks and uncertainties affecting the Unilever Group are described in the Unilever Group’s filings with the London Stock Exchange, Euronext Amsterdam and the SEC, including in the Annual Report on Form 20-F 2025 and the Unilever Annual Report and Accounts 2025.
