IFF Provides Business Update

New York (June 8, 2020) - IFF (NYSE:IFF) (Euronext Paris: IFF) (TASE: IFF), a leading innovator of taste, scent and nutrition, today provided an update on its business performance for the first eight weeks of the second quarter 2020 and provided additional commentary regarding ongoing business dynamics during theCOVID-19 pandemic.

“TheCOVID-19 pandemic has showcased the dedication and persistence of our global team and the diversity and resiliency of our business,” said Andreas Fibig, IFF Chairman and CEO. “These past eight weeks have coincided with the peak of restrictive regulatory actions around the world. We remain fortunate that most of our business is inend-markets and categories with relative strength, but we are not totally immune. During one of the most challenging periods all of us have seen, we’ve successfully adapted our ways of working to responsibly manage the business, while continuing to deliver innovative solutions to our customers. I am incredibly proud of how our teams have responded during this unprecedented event and that ouryear-to-date currency neutral sales are up low single digits compared to last year. Given the easing of restrictions in many countries that we are seeing in June, I am cautiously optimistic that sales and profit will improve as economic activity resumes.”

Preliminary business performance through first eight weeks of Q2 2020:

• Sales declined by 3% on a currency neutral basis and 7% on a reported basis compared to the corresponding period last year, driven by continued pressure in certainend-market categories, across select countries and particularly with small- andmid-sized customers as a result of theCOVID-19 pandemic.

• IFF experienced solid demand for products used in packaged food, beverage, hygiene and disinfection categories. Representing approximately 85% of total 2019 revenue, currency neutral sales for this portion grew by 3% compared to the corresponding period last year, with Consumer Fragrances up double-digits.

• The categories most exposed to the temporary disruptions of consumer access to retail markets (Fine Fragrance) and away-from-home channels (Food Service), experienced significant pressure. Representing approximately 15% of total 2019 revenue, currency neutral sales for this portion declined approximately 40% compared to the corresponding period last year.

• From a geographic perspective, North America showed resiliency, while the emerging markets, especially India and several Latin American countries, were impacted byCOVID-19 and strong regulatory restrictions put in place to protect communities. In China, where restrictions have already eased, growth has sequentially improved.

• Lower sales volumes and an unfavorable mix, combined with additionalCOVID-19 manufacturing and procurement costs, reduced gross profit by 12% on a reported basis compared to the corresponding period last year. Disciplined cost management and continued productivity initiatives partly offset these challenges.

The Company quickly adapted its operations to responsibly operate the business while continuing to meet customer demand, despite some logistics challenges around the world. Nearly all our global Creative Centers and manufacturing facilities continue to operate. Across the IFF global network, teams have begun proceeding through the different phases of ourreturn-to-work protocol. This gradualreturn-to-work strategy is intended to prioritize the safety of all IFF employees and create a new way of working that allows IFF to continue meeting customers’ needs, while abiding by government mandates and regulations.

Use ofNon-GAAP Financial Measures

We provide in this press release anon-GAAP financial measure: currency neutral sales.

Currency Neutral metrics eliminate the effects that result from translating international currency to U.S. dollars. We calculate currency neutral numbers by comparing current year results to the prior year results restated at exchange rates in effect for the current year based on the currency of the underlying transaction. Mayquarter-to-date 2020 sales byend-market, as referenced in the second and third bullets above, are only available on a Currency Neutral basis, as we currently are not able to translate sales from international currency to U.S. dollars on the basis of suchend-markets without unreasonable effort due to the current structure of our reporting systems.

Thesenon-GAAP measures are intended to provide additional information regarding our underlying operating results and comparable year-over-year performance. Such information is supplemental to information presented in accordance with GAAP and is not intended to represent a presentation in accordance with GAAP. In discussing our historical and expected future results and financial condition, we believe it is meaningful for investors to be made aware of and to be assisted in a better understanding of, on aperiod-to-period comparable basis, financial amounts both including and excluding these identified items, as well as the impact of exchange rate fluctuations. Thesenon-GAAP measures should not be considered in isolation or as substitutes for analysis of the Company’s results under GAAP and may not be comparable to other companies’ calculation of such metrics.
