In the opinion of management, the financial statements reflect all adjustments, which are of a normal recurring nature, necessary for a fair statement of the financial position, results of operations, and cash flows for the interim periods. The results for the nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2023 (as amended, the “2023 Form 10-K”). Certain prior year amounts in the Condensed Consolidated Statements of Cash Flows have been reclassified to conform to the current year presentation.

With a presence around the world, including operations in over 25 countries, the Company’s customers include thousands of the world’s most advanced and specialized steel, aluminum, automotive, aerospace, offshore, container, mining, and metalworking companies. Quaker Houghton develops, produces, and markets a broad range of formulated chemical specialty products and offers chemical management services, which the Company refers to as Fluidcare TM , for various heavy industrial and manufacturing applications sold in its three reportable segments: (i) Americas; (ii) Europe, Middle East and Africa (“EMEA”); and (iii) Asia/Pacific. Hyper-inflationary economies Argentina’s and Türkiye’s economies were considered hyper-inflationary under U.S. GAAP effective July 1, 2018 and April 1, 2022, respectively. As of, and for the three and nine months ended September 30, 2024, the Company's Argentine and Turkish subsidiaries together represented approximately 1% and 2% of the Company’s consolidated total assets and net sales, respectively.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Acquisitions	Business Acquisitions July 2024, the Company acquired the Sutai Group (“Sutai”), for approximately $16.2 million, including an initial cash payment of $14.6 million, subject to routine and customary post-closing adjustments related to working capital and net indebtedness levels, as well as earn-out provisions with an initial estimated payout of $1.6 million related to the finalization of 2024 and 2025 earnings. Assets acquired included cash and cash equivalents of $5.5 million. The Company recorded incremental income of $0.4 million during the three and nine months ended September 30, 2024 relating to adjustments to these earnout provisions in Other income (expense), net on the Condensed Consolidated Statements of Operations. As of September 30, 2024, the Company has remaining earnout liabilities recorded on its Condensed Consolidated Balance Sheet of $1.2 million. Sutai is based in Japan and provides impregnation treatment products and services to the automotive and other industries. Sutai is reported as part of the Asia/Pacific reportable segment. This acquisition strengthens Quaker Houghton’s technology portfolio, enabling the Company to better support and optimize production processes for customers across the Japanese, Asia Pacific and global markets. The Company allocated $3.1 million of the purchase price to intangible assets and recognized $5.5 million of goodwill in the Asia/Pacific segment, none of which is deductible for tax purposes. The goodwill is primarily attributable to expected growth synergies. As of September 30, 2024, the allocation of the purchase price has not been finalized. During February 2024, the Company acquired I.K.V. Tribologie IKVT and its subsidiaries (“IKV”) for $35.2 million, including an initial cash payment of $29.7 million, subject to routine and customary post-closing adjustments related to working capital and net indebtedness levels as well as earn-out provisions related to the finalization of 2023 earnings. Assets acquired included approximately $4.8 million of cash and cash equivalents. IKV, which is part of the Company’s EMEA segment, specializes in high-performance lubricants and greases, including original equipment manufacturer first-fill greases that are primarily used in the automotive, aerospace, electronics, and other industrial markets. The acquisition of IKV strengthens the Company’s position in first-fill greases. The Company allocated $15.0 million of the purchase price to intangible assets, comprised of approximately $11.1 million of customer relationships to be amortized over 16 years; $3.2 million of product technologies to be amortized over 14 years; and $0.7 million of trademarks to be amortized over 5 years. In addition, the Company recognized $16.4 million of goodwill in the EMEA segment, none of which is deductible for tax purposes. The goodwill is primarily attributable to expected cost and growth synergies. In July 2024, the 2023 earnings were finalized and the Company made a payment of $5.5 million in connection with the post-closing adjustments and earn-out provision. As of September 30, 2024, the allocation of the purchase price has been finalized. The results of operations of Sutai and IKV subsequent to the acquisition dates are included in the unaudited Condensed Consolidated Statements of Operations for the three and nine months ended September 30, 2024.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards Recently Issued Accounting Standards Not Yet Adopted The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures in November 2023. This ASU expands on reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses, defined as those expenses that are regularly provided to the chief operating decision maker (“CODM”) and included in the reported measure of segment profit or loss. ASU 2023-07 is effective for annual reports for fiscal years beginning after December 15, 2023, with early adoption permitted. The Company continues to assess the impact of ASU 2023-07. As part of its preliminary assessment, the Company is in the process of identifying the significant segment expenses and other information regularly provided to the CODM and included in the reported measure of segment profitability. The FASB issued ASU 2023-09, Income Taxes (Topic 740) : Improvements to Income Tax Disclosures in December 2023. This ASU requires public business entities to disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate (the “rate reconciliation”) for federal, state, and foreign income taxes. It also requires greater detail about individual reconciling items in the rate reconciliation to the extent the impact of those items exceeds a specified threshold. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. The Company is currently evaluating the disclosure requirements of this standard and the impact on its consolidated financial statements.

Segment Reporting, Measurement Disclosures [Abstract]
Business Segments	Business Segments The Company’s operating segments, which are consistent with its reportable segments, reflect the structure of the Company’s internal organization, the method by which the Company’s resources are allocated, and the manner by which the CODM assesses the Company’s performance. The Company has three reportable segments: (i) Americas; (ii) EMEA; and (iii) Asia/Pacific. Segment operating earnings for each of the Company’s reportable segments are comprised of the segment’s net sales less directly related Cost of goods sold (“COGS”) and Selling, general and administrative expenses (“SG&A”).

Restricted Stock Awards During the nine months ended September 30, 2024, the Company granted 872 non-vested restricted share awards under its long-term incentive plan (“LTIP”) , which are subject to time-based vesting, generally over one to three years. As of September 30, 2024, unrecognized compensation expense related to non-vested restricted shares was $2.1 million, to be recognized over a weighted average remaining period of 1.0 year. Restricted Stock Units During the nine months ended September 30, 2024, the Company granted 59,678 restricted stock units under its LTIP , which are subject to time-based vesting, generally over one to three years. The fair value of these grants is based on the closing price of the Company’s common stock on the date of grant. As of September 30, 2024, unrecognized compensation expense related to non-vested restricted stock units was $7.9 million, to be recognized over a weighted average remaining period of 1.5 years. Performance Stock Units As a component of its LTIP, the Company grants performance-based stock unit awards (“PSUs”). The number of shares that may ultimately be issued as settlement for each award may range from 0% up to 200% of the target award, subject to the achievement of the Company’s market-based total shareholder return (“TSR”) metric relative to the performance of a selected peer group, and separately the achievement of a performance-based return on invested capital (“ROIC”) measure. The service vesting period required for the PSUs is generally three years and the measurement period of the market-based and performance objectives is generally from January 1 of the year of grant through December 31 of the year prior to issuance of the shares. As mentioned above, a portion of the Company’s PSUs are subject to the achievement of the Company’s TSR relative to the performance of a selected peer group. For PSUs granted prior to 2024, the Company’s peer group was the S&P Midcap 400 Materials group. For PSUs subject to relative TSR performance granted in 2024, the Company made an election to change peer groups to the S&P 1500 Chemical group. Compensation expense for PSUs is measured based on the grant date fair value and is recognized on a straight-line vesting method basis over the applicable vesting period. During the nine months ended September 30, 2024, the Company granted 21,019 PSUs with a ROIC condition at a grant date fair value of $200.16 per unit, which was based on the closing trading price of the Company’s common stock on the date of grant. During the nine months ended September 30, 2024, the Company granted 20,883 PSUs with a relative TSR condition. These PSUs are valued using a Monte Carlo simulation on the grant date and had a grant-date fair value of $234.19 per unit, which was developed based on the assumptions set forth in the table below: 2024 Risk-free interest rate 4.55% Dividend yield 0.91% Expected term (years) 3.0 As of September 30, 2024, there was approximately $10.7 million of total unrecognized compensation cost related to PSUs, which the Company expects to recognize over a weighted-average period of 2.1 years.

The amended credit facility (the “Credit Facility”) established (A) a $150.0 million Euro equivalent senior secured term loan (the “Euro Term Loan”), (B) a $600.0 million senior secured term loan (the “U.S. Term Loan”), and (C) a $500.0 million senior secured revolving credit facility (the “Revolver”), each maturing in June 2027. The Company has the right to increase the amount of the Credit Facility by an aggregate amount not to exceed the greater of $300.0 million or 100% of Consolidated EBITDA, subject to certain conditions including the agreement to provide financing by any lender providing such increase. As of September 30, 2024, the Company was in compliance with all of the Credit Facility covenants. See Note 19 of Notes to Consolidated Financial Statements in the Company’s 2023 Form 10-K. The weighted average variable interest rates incurred on the outstanding borrowings under the Credit Facility during the three and nine months ended September 30, 2024 were approximately 6.1% and 6.2%, respectively. As of September 30, 2024, the interest rate on the outstanding borrowings under the Credit Facility was approximately 5.8%.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Hedging Activities	Hedging Activities The Company’s ongoing business operations expose it to various risks, including fluctuating foreign exchange rates and interest rate risk. To manage these risks, the Company periodically enters into derivative financial instruments, such as foreign exchange forward contracts and interest rate swap agreements. The Company does not hold or enter into derivative financial instruments for trading or speculative purposes. Foreign Exchange Forward Contracts The Company uses foreign exchange forward contracts to economically hedge the impact of the variability in exchange rates on certain assets and/or liabilities denominated in foreign currencies. These forward contracts are marked-to-market at each reporting date. Changes in the fair value of the underlying instrument and settlements are recognized in earnings in Other income (expense), net. The fair value of the forward contract is determined from sources independent of the Company, including the financial institutions which are party to the derivative instruments. Open foreign exchange forward contracts as of September 30, 2024 were entered into as hedges of Japanese yen and Mexican peso against the U.S. dollar and had the following notional U.S. dollar values: Currency September 30, Mexican Peso $ 13,700 Japanese Yen 10,000 $ 23,700 Open foreign exchange forward contracts as of September 30, 2024 had maturities occurring over a period of one month. Interest Rate Swaps In order to manage the Company’s exposure to variable interest rate risk associated with the Credit Facility, such as the Secured Overnight Financing Rate (“SOFR”), in the first quarter of 2023, the Company entered into $300.0 million notional amounts of three-year interest rate swaps to convert a portion of the Company’s variable-rate borrowings into a fixed-rate obligation. See Note 14 of Notes to Condensed Consolidated Financial Statements. These interest rate swaps are designated as cash flow hedges and, as such, the contracts are marked-to-market at each reporting date with any unrealized gains or losses included in AOCI to the extent effective and reclassified to interest expense in the period during which the hedged transactions affect earnings or it becomes probable that the forecasted transaction will not occur. The balance sheet classification and fair values of the Company’s derivative instruments, which are Level 2 measurements, are as follows: Derivatives instruments Condensed Consolidated Balance Sheets Location September 30, December 31, Interest rate swaps: Other accrued liabilities $ 373 $ — Other non-current assets — 1,828 Foreign currency forward contracts: Other accrued liabilities 71 159 The following table presents the net unrealized (loss) gain deferred to AOCI: Derivatives designated as cash flow hedges September 30, December 31, Interest rate swaps AOCI $ (287) $ 1,407 The following table presents the location and the amount of net gain or loss recognized in the Company’s Condensed Consolidated Statements of Operations related to derivative instruments: Three Months Ended Nine Months Ended Derivative instruments Condensed Consolidated Statements of Operations 2024 2023 2024 2023 Interest rate swaps Interest expense, net $ 1,295 $ 1,198 $ 3,854 $ 2,259 Foreign exchange forward contracts Other (expense) income, net (1,308) (29) (2,040) 2,107 Total $ (13) $ 1,169 $ 1,814 $ 4,366

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies As previously disclosed in its 2023 Form 10-K, the Company is party to certain environmental matters and other litigation. See Note 25 of Notes to Consolidated Financial Statements in the Company’s 2023 Form 10-K. During the three and nine months ended September 30, 2024, there have been no significant changes to the facts or circumstances of any of the previously disclosed matters. Although there can be no assurance regarding the outcome of any of the ongoing environmental matters or litigation, the Company believes that it has made adequate accruals for costs and liabilities associated with these matters. The Company has accrued approximately $6 million as of September 30, 2024 and December 31, 2023, respectively, for these ongoing matters. The Company previously disclosed in its 2023 Form 10-K that one of its North American production facilities experienced an electrical fire in 2021 that resulted in property damage and the temporary shutdown of production. The Company and its insurance carrier reviewed the impact of the electrical fire on the production facility’s operations as it relates to a potential business interruption insurance claim. In July 2024, the Company and its insurance carrier settled this claim for $1.0 million. In December 2021, the Company completed its acquisition of Coral Chemical Company (“Coral”), a privately held, U.S.-based provider of metal finishing fluid solutions. Subsequent to the acquisition, the Company and the sellers of Coral (the “Sellers”) have worked to finalize certain post-closing adjustments. During the second quarter of 2022, after failing to reach resolution, the Sellers filed suit asserting certain amounts owed related to tax attributes of the acquisition. Since the second quarter of 2022, there have been no material changes to the facts and circumstances of the claim asserted by the Sellers, and the Company continues to believe the potential range of exposure for this claim is $0 to $1.5 million. In addition, during the three and nine months ended September 30, 2024, there are no new environmental matters or litigation that the Company believes will have a material adverse effect on the Company’s results of operations, cash flows, or financial condition.
