Q1 2021 Earnings Supplemental Data May 14, 2021 Disclaimer Forward-Looking Statements: This presentation and the related conference call includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward looking statements reflect the current expectations of Diversey Holdings Ltd. and its subsidiaries (the “Company”) and projections with respect to, among other things, its financial condition, results of operations, plans, objectives, future performance, business, guidance, long term margins and other financial goals and value creation algorithms. These statements may be preceded by, followed by or include the words “anticipate,” “estimate,” “expect,” “project,” “plan,” “intend,” “believe,” “should“, "can have,” “likely,” “will,” “expect” and the negatives thereof and other words and terms of similar meaning. Forward-looking statements include all statements that are not historical facts. Forward- looking statements are based on information available at the time those statements are made and/or management’s good faith beliefs and assumptions as of that time with respect to future events. There is no assurance that any forward-looking statements will materialize. Such forward-looking statements are subject to various risks and uncertainties. Accordingly, there are or will be important factors that could cause actual outcomes or results to differ materially from those indicated in these statements. You are cautioned not to place undue reliance on forward- looking statements, which reflect expectations only as of this date. The Company undertakes no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise. Market and Industry Data: This presentation includes information concerning economic conditions, the Company’s industry, the Company’s markets and the Company’s competitive position that is based on a variety of sources, including information from independent industry analysts and publications, as well as the Company’s own estimates and research. The Company’s estimates are derived from publicly available information released by third party sources, as well as data from its internal research, and are based on such data and the Company’s knowledge of its industry, which the Company believes to be reasonable. The independent industry publications used in this presentation were not prepared on the Company’s behalf. This information involves many assumptions and limitations, and you are cautioned not to give undue weight to these estimates. The Company has not independently verified the accuracy or completeness of the data contained in these industry publications and other publicly available information. Accordingly, we make no representations as to the accuracy or completeness of that data nor do we undertake to update such data after the date of this presentation. Non-GAAP Measures: This presentation contains financial measures, including Adjusted EBITDA and EBITDA, which are not recognized under generally accepted accounting principles in the United States (“GAAP”). The Company believes that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance and assists in comparisons with other companies, some of which use similar non-GAAP financial information to supplement their GAAP results. The non-GAAP financial information is presented for supplemental informational purposes only, and should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from similarly-titled non-GAAP measures used by other companies. Adjusted EBITDA, and EBITDA have limitations as analytical tools, and you should not consider these measures either in isolation or as a substitute for other methods of analyzing the results as reported under GAAP. For a reconciliation of historical non-GAAP financial measures to the most closely comparable GAAP measures, see the appendix to this presentation. 2 Today’s Presenters Phil Wieland Todd Herndon Chief Executive Officer Chief Financial Officer 3 First Quarter 2021 Highlights • 2% top line growth vs pre-COVID baseline • Continued Adjusted EBITDA growth and margin expansion • No supply disruptions from Texas freeze • Implementing price increases to offset raw material inflationary environment • Significant net new business wins • Customer NPS at record levels • Meaningful progress on strategic plan Q1 2021 Results Adjusted EBITDA $MM; % Margin * 92 93 14.1% 14.7% 52 8.4% Q1 2019 Q1 2020 Q1 2021 (Pre-COVID Baseline) (COVID Year) * See non-GAAP definitions and reconciliations in appendix 4 Market Leader in Hygiene, Infection Prevention, and Cleaning Solutions Diversey At-a-Glance 95+ $2.6Bn 15%+ ~8,500 Years of History 2020 Revenue 2020 Adj.
