DEAR FELLOW SHAREHOLDER:

I am pleased to report that 2025 represented a year of continued progress for IFF, characterized by disciplined execution against clearly defined priorities. In a dynamic operating environment, management remained focused on advancing the Company’s strategic agenda, strengthening the balance sheet and delivering on its financial commitments.

During the year, we continued to enhance how the Company operates. The implementation of a business-led operating model has strengthened accountability, reinforced customer focus and improved the speed and quality of decision-making, with a clear emphasis on margin improvement, cash generation and execution consistency. Management delivered on full-year guidance across revenue and EBITDA, while reinvesting in the business through productivity initiatives and disciplined cost management.

The Company also took deliberate actions to strengthen its financial foundation and further focus the portfolio. We completed the divestitures of Pharma Solutions, Nitrocellulose and René Laurent businesses, and announced an agreement to sell the Soy Crush, Concentrates and Lecithin business. In addition, the Company commenced an evaluation of strategic alternatives for the Food Ingredients business as part of an ongoing effort to concentrate resources on core businesses with stronger growth and return characteristics. As a result of these actions, together with disciplined capital allocation, net debt to credit adjusted EBITDA was reduced to approximately 2.6x from 3.8x at the end of 2024.*

Consistent with the Company’s capital allocation framework – which prioritizes balance sheet strength, investment in the business and the return of excess capital to shareholders – the Board authorized a $500 million share repurchase program, reflecting improved financial flexibility and confidence in IFF’s long-term value creation.

During 2025, the Board continued its evolution to ensure it possesses the appropriate mix of skills, experience and independence to oversee the next phase of the Company’s transformation. The Board welcomed Virginia Drosos, Paul Fribourg, Richard Mulligan, Jesus Mantas and Brett Icahn, each of whom brings relevant leadership and industry expertise. I would also like to thank Margarita Paláu-Hernández and Vincent Intrieri for their dedication and service to the board prior to their departure in October. Additionally, I’d like to thank John Ferraro, Mark Costa and Kathryn Boor for their valued contributions, as they will not stand for re-election at the Annual Meeting.

As Chair, I remain firmly committed to high standards of governance and robust oversight of strategy, performance and risk. Since assuming this role at the 2025 Annual Shareholder Meeting, my focus has been on ensuring the Board maintains a strong alignment between strategy, execution, performance outcomes and shareholder interests.

Looking ahead, the Board and management remain focused on disciplined execution and accountability. With a more focused portfolio, a strengthened balance sheet and a clear capital allocation framework, the Company is entering the next phase of its transformation with well-defined priorities and a continued emphasis on delivering sustainable, long-term shareholder value.

In closing, I would like to thank our management team and our colleagues for your commitment every day to improving IFF, and our customers for the confidence and trust you place in us.

Finally, to you, our shareholders, thank you for your continued support and confidence.

Sincerely,

Kevin O’Byrne

Chair of the Board of Directors
