Quaker Houghton Fourth Quarter and Full Year 2024 Results Investor Conference Call

Regulation G The attached charts include Company information that does not conform to generally accepted accounting principles (“GAAP”). Management believes that an analysis of this data is meaningful to investors because it provides insight with respect to ongoing operating results of the Company and helps investors to evaluate the financial results of the Company. These measures should not be viewed as an alternative to GAAP measures of performance. Furthermore, these measures may not be consistent with similar measures provided by other companies. This data should be read in conjunction with the fourth quarter and full year earnings news release, dated February 24, 2025, which has been furnished to the Securities and Exchange Commission (“SEC”) on Form 8-K. Forward-Looking Statements This presentation contains “forward-looking statements” that fall under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 and the Securities Act of 1933, as amended. These statements can be identified by the fact that they do not relate strictly to historical or current facts. We have based these forward-looking statements on assumptions, projections and expectations about future events that we believe are reasonable based on currently available information, including statements regarding the potential effects of economic downturns; tariffs, including uncertainty surrounding changes in tariffs; inflation and global supply chain constraints on the Company’s business, results of operations, and financial condition; our expectation that we will maintain sufficient liquidity and remain in compliance with the terms of the Company’s credit facility; expectations about future demand and raw material costs; and statements regarding the impact of increased raw material costs and pricing initiatives. These forward- looking statements include statements with respect to our beliefs, plans, objectives, goals, expectations, anticipations, intentions, financial condition, results of operations, future performance, and business, which may differ materially from our actual results, including but not limited to the potential benefits of acquisitions and divestitures, the impacts on our business as a result of global supply chain constraints, and our current and future results and plans and statements that include the words “may,” “could,” “should,” “would,” “believe,” “expect,” “anticipate,” “estimate,” “intend,” “outlook, “target”, “possible”, “potential”, “plan” or similar expressions. Such statements include information relating to current and future business activities, operational matters, capital spending, and financing sources. A major risk is that demand for the Company’s products and services is largely derived from the demand for its customers’ products, which subjects the Company to uncertainties related to downturns in a customer’s business and unanticipated customer production slowdowns and shutdowns. Other major risks and uncertainties include, but are not limited to inflationary pressures, including increases in raw material costs; supply chain constraints and the impacts of economic downturns; customer financial instability; high interest rates and their impact on our and our customers’ business operations; the impacts from acts of war, terrorism and military conflicts, including those in Ukraine and the Middle East as well as economic, political and governmental actions taken by various governments and governmental organizations in response; economic and political disruptions particularly in light of numerous elections globally and the possibility of regime changes; the possibility of economic recession; legislative and regulatory developments including changes to existing laws and regulations, or the way they are interpreted, applied or enforced; tariffs, trade restrictions, and the economic and other sanctions imposed by other nations on Russia and Belarus and/or other government organizations; suspensions of activities in Russia by many multinational companies; foreign currency fluctuations; significant changes in applicable tax rates and regulations; future terrorist attacks and other acts of violence; the impacts of consolidation in our industry, including loss or consolidation of a major customer, the effects of climate change, fires, or other natural disasters; and the potential occurrence of cyber-security breaches, cyber-security attacks and other technology outages and security incidents. Furthermore, the Company is subject to the same business cycles as those experienced by our customers in the steel, automobile, aircraft, industrial equipment, aluminum and durable goods industries. Our forward-looking statements are subject to risks, uncertainties and assumptions about the Company and its operations that are subject to change based on various important factors, some of which are beyond our control. These risks, uncertainties, and possible inaccurate assumptions relevant to our business could cause our actual results to differ materially from expected and historical results. All forward-looking statements included in this press release, including expectations about business conditions during 2024 and future periods, are based upon information available to the Company as of the date of this press release, which may change. Therefore, we caution you not to place undue reliance on our forward-looking statements. For more information regarding these risks and uncertainties as well as certain additional risks that we face, refer to the Risk Factors section, which appears in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2024 and in subsequent reports filed from time to time with the Securities and Exchange Commission. We do not intend to, and we disclaim any duty or obligation to, update or revise any forward-looking statements to reflect new information or future events or for any other reason. This discussion is provided as permitted by the Private Securities Litigation Reform Act of 1995. ©2025 Quaker Houghton. All Rights Reserved 2 Forward-Looking Statements

The information included in this presentation includes non-GAAP (unaudited) financial information that includes EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP operating income, non-GAAP operating margin, non-GAAP net income and non-GAAP earnings per diluted share. The Company believes these non-GAAP financial measures provide meaningful supplemental information as they enhance a reader’s understanding of the financial performance of the Company, facilitate a comparison among fiscal periods, and exclude items that management believes are not indicative of future operating performance or core to the Company’s operations. Non-GAAP results are presented for supplemental informational purposes only and should not be considered a substitute for the financial information presented in accordance with GAAP. In addition, our definitions of EBITDA, adjusted EBITDA, adjusted EBITDA margin, non-GAAP operating income, non-GAAP operating margin, non-GAAP net income, and non-GAAP earnings per share, as discussed and reconciled below to the most comparable GAAP measures, may not be comparable to similarly named measures reported by other companies. The Company presents EBITDA which is calculated as net income attributable to the Company before depreciation and amortization, interest expense, net, and taxes on income before equity in net income of associated companies. The Company also presents adjusted EBITDA which is calculated as EBITDA plus or minus certain items that management believes are not indicative of future operating performance or not considered core to the Company’s operations. In addition, the Company presents non-GAAP operating income which is calculated as operating income plus or minus certain items that management believes are not indicative of future operating performance or considers core to the Company’s operations. Adjusted EBITDA margin and non-GAAP operating margin are calculated as the percentage of adjusted EBITDA and non-GAAP operating income to consolidated net sales, respectively. The Company believes these non-GAAP measures provide transparent and useful information and are widely used by analysts, investors, and competitors in our industry as well as by management in assessing the operating performance of the Company on a consistent basis. Additionally, the Company presents non-GAAP net income and non-GAAP earnings per diluted share as additional performance measures. Non-GAAP net income is calculated as adjusted EBITDA, defined above, less depreciation and amortization, interest expense, net, and taxes on income before equity in net income of associated companies, in each case adjusted, as applicable, for any depreciation, amortization, interest or tax impacts resulting from the non-core items identified in the reconciliation of net income attributable to the Company to adjusted EBITDA. Non-GAAP earnings per diluted share is calculated as non-GAAP net income per diluted share as accounted for under the “two-class share method.” The Company believes that non-GAAP net income and non-GAAP earnings per diluted share provide transparent and useful information and are widely used by analysts, investors, and competitors in our industry as well as by management in assessing the performance of the Company on a consistent basis. As it relates to future projections for the Company as well as other forward-looking information contained in this press release, the Company has not provided guidance for comparable GAAP measures or a quantitative reconciliation of forward-looking non-GAAP financial measures to the most directly comparable U.S. GAAP measure because it is unable to determine with reasonable certainty the ultimate outcome of certain significant items necessary to calculate such measures without unreasonable effort. These items include, but are not limited to, certain non-recurring or non-core items the Company may record that could materially impact net income. These items are uncertain, depend on various factors, and could have a material impact on the U.S. GAAP reported results for the guidance period. The following charts should be read in conjunction with the Company’s fourth quarter and full year earnings news release dated February 24, 2025, which has been furnished to the Securities and Exchange Commission on Form 8-K, the Company’s Annual Report for the year ended December 31, 2024. These documents may contain additional explanatory language and information regarding certain of the items included in the following reconciliations. ©2025 Quaker Houghton.
