IFF Reports First Quarter 2020 Results

NEW YORK, N.Y., (May 11, 2020) - International Flavors & Fragrances Inc. (NYSE: IFF) (Euronext Paris: IFF) (TASE: IFF) reported financial results for the first quarter ended March 31, 2020.

First Quarter 2020 Consolidated Summary:

¹ Schedules at the end of this release contain reconciliations of reported GAAP to non-GAAP metrics.

Management Commentary

“I am incredibly proud of how everyone at IFF has delivered for our customers around the world through the most challenging of circumstances,” said Andreas Fibig, IFF Chairman and CEO. “Our strong first quarter performance is a testament to the strength of our business and IFF’s role as an essential partner in the global consumer product supply chain. We realized strong top and bottom-line growth, which reflects the breadth of our diverse portfolio as well as the important role we play in the everyday life of consumers. Even in the midst of increased demand and a challenging operating environment, our teams continued to deliver solid synergies related to the Frutarom acquisition, advanced our DuPont Nutrition & Biosciences integration planning and helped to support those protecting our communities, including through the creation of more than 65 tons of hand sanitizer and the development of a new scent, ‘HOPE 2020,’ in record time.

“Our ability to pivot quickly and adapt our daily operations has enabled us to responsibly operate our business while continuing to meet customer demand, despite a few logistics hurdles around the world. As regulatory restrictions aimed at protecting public health shifted worldwide through the quarter, we have worked through these challenges to realize minimal disruption across our production and supply chain. Protecting the health and safety of our colleagues, especially those still coming to our facilities, continues to be paramount as we navigate the challenges presented by COVID 19.

IFF Executive Vice President and CFO, Rustom Jilla commented, “We leveraged our mid-single digit sales growth to deliver solid adjusted operating margin expansion in the first quarter. Now more than ever, IFF’s broad based exposure across regions, categories and customers positions us to remain resilient through these uncertain times. We are fortunate that the majority of our revenue comes from packaged food, beverage and personal care and hygiene products, where there is relative strength. Having said that, we are not entirely immune as categories such as Fine Fragrances, Cosmetic Actives, Fragrance Ingredients and Food Service are exhibiting challenges and we are seeing additional costs related to COVID-19. It also is clear that in the near-term, global conditions will be extraordinarily volatile and unpredictable, leading us to withdraw our full year financial guidance. We will continue to effectively manage our balance sheet by taking actions to generate strong cash flow, and to maintain ample liquidity even through a prolonged global downturn.

Mr. Fibig continued, “As we gain more visibility in the second quarter and beyond, we expect to share additional updates on the performance and outlook for our business. We’ve been through challenging and uncertain times before as a company and believe that we’re well positioned to successfully manage through this and emerge as an even stronger company.”

Business Environment Update Amid COVID-19

As the COVID-19 pandemic has spread globally, IFF is experiencing significant demand for ingredients and solutions used in certain consumer products, including packaged food, beverage and hygiene and disinfection, which represents approximately 85% of the Company’s total 2019 revenue. At the same time, IFF is seeing weakness across other offerings exposed to temporary disruptions of consumer access to retail markets, such as Fine Fragrance and Cosmetic Actives, and away-from-home channels, such as Food Service.

IFF continues to adapt quickly to the current environment, with a focus on mitigating the near-term impact while positioning for continued long-term success following the crisis and remains optimistic on seeing improvement as the pandemic abates.

2020 Full Year Financial Guidance:

As the COVID-19 pandemic continues to evolve, there is uncertainty around its ultimate impact; therefore, the Company’s full year financial results cannot be reasonably estimated at this time and have been withdrawn.

Cautionary Statement Under The Private Securities Litigation Reform Act of 1995

This press release includes “forward-looking statements” under the Federal Private Securities Litigation Reform Act of 1995, including statements regarding the expected impact of the COVID 19 pandemic on the Company’s near term results, including sales and profit in the second quarter of 2020, and revenue from its categories with retail channel exposure, such as Fine Fragrance, Cosmetic Actives and Food Service; the expected impact of the COVID 19 pandemic on the global economy; the Company’s expectations with respect to generating cash flow and its liquidity position to manage a prolonged global economic downturn; anticipated increased costs relating to managing through the COVID 19 pandemic; expected updates from the Company on future performance and outlook for the business in 2020; the Company’s ability to manage through the COVID 19 pandemic and to mitigate the near-term impact; and the Company’s belief that it will see improvement in its business as the pandemic abates.These forward-looking statements are qualified in their entirety by cautionary statements and risk factor disclosures contained in the Company’s Securities and Exchange Commission filings, including the Company’s Annual Report on Form 10-K filed with the Commission on March 3, 2020 and subsequent filings with the SEC. The Company wishes to caution readers that certain important factors may have affected and could in the future affect the Company’s actual results and could cause the Company’s actual results for subsequent periods to differ materially from those expressed in any forward-looking statements made by or on behalf of the Company. With respect to the Company’s expectations regarding these statements, such factors include, but are not limited to: (1) the effect of economic conditions in the industries and markets in which IFF operates in the U.S. and globally and any changes therein, including financial market conditions, fluctuations in commodity prices, interest rates and foreign currency exchange rates, levels of end market demand, the impact of weather conditions, natural disasters, public health issues, epidemics and pandemics, including the novel coronavirus (COVID-19), or the fear of such events, and the financial condition of IFF’s customers and suppliers; (2) the risks to the Company’s business from the COVID 19 pandemic, including operational risks, supply chain risks, and customer related-risks; (3) risks related to the integration of the Frutarom business, including whether we will realize the benefits anticipated from the acquisition in the expected time frame; (4) unanticipated costs, liabilities, charges or expenses resulting from the Frutarom acquisition, (5) the impact of the outcome of legal claims, regulatory investigations and litigation, (6) the increase in the Company’s leverage resulting from the additional debt incurred to pay a portion of the consideration for Frutarom and its impact on the Company’s liquidity and ability to return capital to its shareholders, (7) the Company’s ability to successfully market to its expanded and decentralized Taste and Frutarom customer base, (8) the Company’s ability to effectively compete in its market and develop and introduce new products that meet customers’ needs, (9) the Company’s ability to successfully develop innovative and cost-effective products that allow customers to achieve their own profitability expectations, (10) the impact of the disruption in the Company’s manufacturing operations, (11) the impact of a disruption in the Company’s supply chain, including the inability to obtain ingredients and raw materials from third parties, (12) volatility and increases in the price of raw materials, energy and transportation, (13) the Company’s ability to comply with, and the costs associated with compliance with, regulatory requirements and industry standards, including regarding product safety, quality, efficacy and environmental impact, (14) the impact of any failure or interruption of the Company’s key information technology systems or a breach of information security, (15) the Company’s ability to react in a timely and cost-effective manner to changes in consumer preferences and demands, (16) the Company’s ability to establish and manage collaborations, joint ventures or partnership that lead to development or commercialization of products, (17) the Company’s ability to benefit from its investments and expansion in emerging markets; (18) the impact of currency fluctuations or devaluations in the principal foreign markets in which it operates; (19) economic, regulatory and political risks associated with the Company’s international operations, (20) the impact of global economic uncertainty on demand for consumer products, (21) the inability to retain key personnel;

(22) the Company’s ability to comply with, and the costs associated with compliance with, U.S. and foreign environmental protection laws, (23) the Company’s ability to realize the benefits of its cost and productivity initiatives, (24) the Company’s ability to successfully manage its working capital and inventory balances, (25) the impact of the failure to comply with U.S. or foreign anti-corruption and anti-bribery laws and regulations, including the U.S. Foreign Corrupt Practices Act, (26) the Company’s ability to protect its intellectual property rights, (27) the impact of the outcome of legal claims, regulatory investigations and litigation, (28) changes in market conditions or governmental regulations relating to our pension and postretirement obligations, (29) the impact of future impairment of our tangible or intangible long-lived assets, (30) the impact of changes in federal, state, local and international tax legislation or policies, including the Tax Cuts and Jobs Act, with respect to transfer pricing and state aid, and adverse results of tax audits, assessments, or disputes, (31) the effect of potential government regulation on certain product development initiatives, and restrictions or costs that may be imposed on the Company or its operations as a result, and (32) the impact of the United Kingdom’s departure from the European Union. New risks emerge from time to time and it is not possible for management to predict all such risk factors or to assess the impact of such risks on the Company’s business. Accordingly, the Company undertakes no obligation to publicly revise any forward-looking statements, whether as a result of new information, future events, or otherwise.

Use of Non-GAAP Financial Measures

We provide in this press release non-GAAP financial measures, including: (i) currency neutral sales; (ii) adjusted operating profit; (iii) adjusted operating profit (margin) ex. amortization; (iv) adjusted EPS; (v) adjusted EPS ex. amortization and (vi) currency neutral adjusted EPS ex amortization.

Our non-GAAP financial measures are defined below.

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.

Adjusted Operating Profit excludes the impact of operational improvement initiatives, integration related costs, restructuring and other charges, net, losses (gains) on sale of assets, Frutarom

acquisition related costs, compliance review & legal defense costs, and N&B transaction related costs (“Operating Profit Items Impacting Comparability”).

Adjusted Operating Profit (Margin) ex. Amortization excludes the impact of Operating Profit Items Impacting Comparability and the amortization of acquisition related intangible assets.

Adjusted EPS excludes the impact of operational improvement initiatives, integration related costs, restructuring and other charges, net, losses (gains) on sale of assets, Frutarom acquisition related costs, compliance review & legal defense costs, N&B transaction related costs, and redemption value adjustment to EPS (often referred to as “Items Impacting Comparability”).

Adjusted EPS ex. Amortization excludes the impact of Items Impacting Comparability and the amortization of acquisition related intangible assets.

These non-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 a period-to-period comparable basis, financial amounts both including and excluding these identified items, as well as the impact of exchange rate fluctuations. These non-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.

In the fourth quarter of fiscal year 2018, we began including Adjusted EPS ex. Amortization as a key non-GAAP financial measure of our business. Full amortization expense of intangible assets acquired in connection with acquisitions will be excluded from Adjusted EPS ex. Amortization calculation. The exclusion of amortization expense allows comparison of operating results that are consistent over time for newly and long-held businesses and with both acquisitive and non-acquisitive peer companies. We believe this calculation will provide a more accurate presentation in this and in future periods in the event of additional acquisitions. Further, this allows the investors to evaluate and understand operating trends excluding the impact on operating income and earnings per diluted share. In addition, the Frutarom acquisition related costs and N&B transaction related costs have been separated from costs related to prior acquisitions. The Frutarom acquisition related costs and N&B transaction related costs represent a significant balance and we believe this amount should be shown separately to provide an accurate presentation of the acquisition related costs. Our GAAP results and GAAP metrics do not change, and this change has no effect on day to day business operations, or how we manage our business.
