Financial Statement Presentation In the opinion of management, the accompanying consolidated financial statements of NewMarket Corporation and its subsidiaries contain all necessary adjustments for the fair presentation of, in all material respects, our consolidated financial position as of June 30, 2026 and December 31, 2025, our consolidated results of operations, comprehensive income, and changes in shareholders' equity for the second quarter and six months ended June 30, 2026 and June 30, 2025, and our cash flows for the six months ended June 30, 2026 and June 30, 2025. All adjustments are of a normal, recurring nature, unless otherwise disclosed. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and the instructions to Rule 10-01 of Regulation S-X of the Securities and Exchange Commission (SEC), but do not include all disclosures required by GAAP for complete annual consolidated financial statements. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the NewMarket Corporation Annual Report on Form 10-K for the year ended December 31, 2025 (2025 Annual Report), as filed with the SEC. The results of operations for the six-month period ended June 30, 2026 are not necessarily indicative of the results to be expected for the full year ending December 31, 2026. Unless the context otherwise indicates, all references to “we,” “us,” “our,” the “company,” and “NewMarket” are to NewMarket Corporation and its consolidated subsidiaries. Supplier Finance Program We offer our vendors a supplier finance program, which allows our vendors to receive payment from a third-party finance provider earlier than our normal payment terms would provide. NewMarket and its subsidiaries are not a party to any arrangement between our vendors and the finance provider, and there are no assets pledged as security or other forms of guarantees provided by NewMarket to the finance provider. For those vendors who opt to participate in the program, we pay the finance provider the full amount of the invoices on the normal due date. At both June 30, 2026 and December 31, 2025, the amount of confirmed invoices outstanding under the supplier finance program was not material. 2. Acquisition of Business We account for acquisitions using the acquisition method of accounting for business combinations under the provisions of Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 805, Business Combinations and have included the results of operations of the acquired business in our Consolidated Statements of Income from the date of acquisition. We develop the allocation of the purchase price of an acquired company to the tangible and intangible assets acquired and liabilities assumed using estimates of fair value. On October 1, 2025, we completed the acquisition of Mars TopCo, LLC, the ultimate parent company of Calca Solutions, LLC (Calca) for $ 218 million. Calca has one manufacturing facility in Louisiana and is the nation's leading producer of Ultra Pure ® and high-purity hydrazine - essential, mission-critical propellants that enable advanced aerospace and defense applications. Calca's products are integral to in-space propulsion systems for satellites, space probes, and other vehicles that operate in the most demanding environments. For more than 70 years, Calca has supplied high-purity hydrazine to the U.S. Department of War's Defense Logistics Agency - Energy. This acquisition was funded by cash on hand and borrowings under our revolving credit facility. Acquisition-related charges totaling $ 1 million consisted primarily of legal and professional fees and are included in selling, general, and administrative expenses in the period incurred. We have initiated a purchase price valuation to determine the fair values of the tangible and intangible assets acquired and liabilities assumed and the amount of goodwill to be recognized as of the acquisition date. The amounts recorded for certain assets and liabilities, including but not limited to deferred taxes, intangible assets, and goodwill, are preliminary and are subject to adjustment if additional information is obtained about facts that existed as of the acquisition date. The final determination of the fair values of certain assets and liabilities will be completed within the measurement period of up to one year from the acquisition date. During the first six months of 2026, intangible assets and goodwill were adjusted by $ 3 million each. 9 Table of Contents NEWMARKET CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) A preliminary allocation of the purchase price of Calca is as follows (in millions): Cash and cash equivalents $ 6 Trade and other accounts receivable, net 4 Inventories 5 Prepaid expenses and other current assets 2 Property, plant, and equipment, net 22 Goodwill 48 Intangible assets 171 Accounts payable ( 5 ) Accrued expenses ( 3 ) Other noncurrent liabilities ( 32 ) Fair value of net assets acquired $ 218 Identified intangible assets acquired consisted of the following (in millions): Fair Value Estimated Useful Lives (in years) Customer base $ 119 9 to 20 Backlog 20 5 Formulas and technology 31 9 to 20 Trademarks and trade names 1 5 Total identified intangible assets $ 171 As part of the acquisition, we recorded $ 48 million of goodwill. The goodwill recognized is attributable to increased access to mission-critical, resilient sectors with a role in global safety, security, and space exploration, as well as the skilled assembled workforce of Calca. All of the goodwill recognized is part of the specialty materials segment, and none is deductible for income tax purposes. 3. Net Sales Our revenues are predominantly derived from the manufacture and sale of petroleum additives products. We sell petroleum additives products across the world to customers located in the North America (the United States and Canada), Latin America (Mexico, Central America, and South America), Asia Pacific, and EMEAI (Europe/Middle East/Africa/India) regions. Our petroleum additives customers primarily consist of global, national, and independent oil companies. Our petroleum additives contracts generally include one performance obligation, which is satisfied at a point in time when products are shipped, delivered, or consumed by the customer, depending on the underlying contracts. Additionally, we have revenue from the manufacture and sale of critical specialty materials products used primarily in solid rocket motors for space launch and military defense applications, as well as propellants that enable advanced aerospace and defense applications and are integral to in-space propulsions systems for satellites and space probes. The sale of specialty materials products is predominantly to customers located in the United States, with limited amounts to customers in other countries. Our specialty materials customers are primarily contractors or subcontractors of the U.S. government, as well as the U.S. government. Specialty materials contracts generally include one performance obligation, which is typically satisfied at a point in time when the products are shipped from the plant sites. In limited cases, we collect funds in advance of shipping product to our customers and recognizing the related revenue. These prepayments from customers are recorded as a contract liability until we recognize the revenue. Some of our contracts also include variable consideration in the form of rebates, including tiered pricing, and/or business development funds. We regularly review these and make adjustments when necessary, recognizing the full amount of any adjustment in the period identified. 10 Table of Contents NEWMARKET CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The following table provides information on our net sales by geographic area.

Segment Information We have two reportable segments – petroleum additives and specialty materials. The petroleum additives segment includes lubricant and fuel additives which are necessary for the efficient and reliable operation of vehicles and machinery. The specialty materials segment includes critical materials used in solid rocket motors for space launch and military defense applications as well as propellants that enable advanced aerospace and defense applications that are integral to in-space propulsion systems for satellites and space probes. The petroleum additives and specialty materials segments are managed separately by the president of Afton and the executive vice president, specialty materials, respectively. The “All other” category shown in the tables below includes the operations of the antiknock compounds business, as well as certain contracted manufacturing and related services associated with Ethyl. We have determined that our chief executive officer is the chief operating decision maker (CODM) who makes key operating decisions and assesses the performance of the reportable segments. The CODM evaluates performance based on segment operating profit and considers budgeted and forecasted variances to actual results in allocating resources to the segments. The segment accounting policies are the same as those described in Note 1 of our 2025 Annual Report. NewMarket Services expenses are billed to the companies in each of the segments and all other businesses based on the services provided. Depreciation on segment property, plant, and equipment, as well as amortization of segment definite-lived intangible assets and lease right-of-use assets are included in segment operating profit. No material transfers occurred between any of the petroleum additives segment, specialty materials segment, and the “All other” category during the periods presented. The table below reports net sales and operating profit by segment, as well as a reconciliation to income before income tax expense, for the second quarter and six months ended June 30, 2026 and June 30, 2025. No single customer accounted for 10% or more of our total net sales in any period presented. 11 Table of Contents NEWMARKET CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Second Quarter Ended June 30, Six Months Ended June 30, (in thousands) 2026 2025 2026 2025 Net sales Petroleum additives Lubricant additives $ 584,024 $ 556,479 $ 1,105,193 $ 1,115,657 Fuel additives 91,549 97,396 180,198 183,772 Total 675,573 653,875 1,285,391 1,299,429 Specialty materials 67,165 42,037 125,306 95,758 All other 4,356 2,597 6,114 4,268 Total net sales $ 747,094 $ 698,509 $ 1,416,811 $ 1,399,455 Segment operating profit Petroleum additives Net sales $ 675,573 $ 653,875 $ 1,285,391 $ 1,299,429 Cost of goods sold ( 463,188 ) ( 448,474 ) ( 872,626 ) ( 886,220 ) Research, development, and testing expenses ( 30,388 ) ( 32,374 ) ( 62,024 ) ( 65,550 ) Other segment items ( 32,627 ) ( 33,192 ) ( 66,372 ) ( 65,717 ) Petroleum additives segment operating profit 149,370 139,835 284,369 281,942 Specialty materials Net sales 67,165 42,037 125,306 95,758 Other segment items ( 44,819 ) ( 31,490 ) ( 90,538 ) ( 62,024 ) Specialty materials segment operating profit 22,346 10,547 34,768 33,734 Total segment operating profit 171,716 150,382 319,137 315,676 All other ( 212 ) ( 1,171 ) ( 1,322 ) ( 1,652 ) Corporate, general, and administrative expenses ( 7,816 ) ( 6,414 ) ( 10,869 ) ( 11,300 ) Interest and financing expenses, net ( 8,818 ) ( 10,735 ) ( 17,589 ) ( 21,435 ) Other income (expense), net 15,468 15,626 32,635 30,512 Income before income tax expense $ 170,338 $ 147,688 $ 321,992 $ 311,801 The significant expense categories of cost of goods sold and research, development, and testing expenses are shown in the above segment operating profit table for the petroleum additives segment and are regularly provided to the CODM.

Earnings Per Share We had 37,224 shares of nonvested restricted stock at June 30, 2026 and 37,202 shares of nonvested restricted stock at June 30, 2025 that were excluded from the calculation of diluted earnings per share, as their effect on earnings per share would be anti-dilutive. The nonvested restricted stock is considered a participating security since the restricted stock contains nonforfeitable rights to dividends. As such, we use the two-class method to compute basic and diluted earnings per share for all periods presented since this method yields the most dilutive result. The following table illustrates the earnings allocation method utilized in the calculation of basic and diluted earnings per share.

Commitments and Contingencies Legal Matters We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see Environmental below. While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows. Environmental We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a potentially responsible party. While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our consolidated financial position, results of operations, and cash flows. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $ 12 million at June 30, 2026 and $ 14 million at December 31, 2025. Of the total accrual, the current portion is included in accrued expenses, and the noncurrent portion is included in other noncurrent liabilities on the Condensed Consolidated Balance Sheets . Our more significant environmental sites include a former plant site in Baton Rouge, Louisiana and a Houston, Texas plant site. Together, the amounts accrued on a discounted basis related to these sites represented approximately $ 7 million of the total accrual above at June 30, 2026 and $ 9 million at December 31, 2025, using discount rates ranging from 3 % to 9 % for both periods.
