1. 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 September 30, 2025 and December 31, 2024, our consolidated results of operations, comprehensive income, and changes in shareholders' equity for the third quarter and nine months ended September 30, 2025 and September 30, 2024, and our cash flows for the nine months ended September 30, 2025 and September 30, 2024. 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, 2024 (2024 Annual Report), as filed with the SEC. The results of operations for the nine-month period ended September 30, 2025 are not necessarily indicative of the results to be expected for the full year ending December 31, 2025.
Unless the context otherwise indicates, all references to “we,” “us,” “our,” the “company,” and “NewMarket” are to NewMarket Corporation and its consolidated subsidiaries.

2. Acquisition of Business
On January 16, 2024, we completed the acquisition of all issued and outstanding ownership units of AMPAC Intermediate Holdings, LLC, the ultimate parent company of American Pacific Corporation (AMPAC), for approximately $697 million. Based in Cedar City, Utah, AMPAC has one operating facility from which it manufactures and sells critical specialty materials primarily used in solid rocket motors for space launch and military defense applications. AMPAC is qualified on many NASA and Department of Defense programs and has been serving space launch and national defense programs for more than 60 years. The acquisition of AMPAC expands our presence in mission-critical, resilient sectors. It was funded by cash on hand and borrowings under our then existing revolving credit facility. The purchase consideration was subject to a customary post-closing adjustment for working capital, which was finalized during the second quarter of 2024.
The fair values of the assets acquired and the liabilities assumed in the AMPAC acquisition are as follows (in millions):
| Cash and cash equivalents | $ | |||||||
| Trade and other accounts receivable, net | ||||||||
| Inventories | ||||||||
| Prepaid expenses and other current assets | ||||||||
| Property, plant, and equipment, net | ||||||||

| Deferred charges and other assets | ||||||||
| Accounts payable | ( | |||||||
| Accrued expenses | ( | |||||||

| Trademarks and trade names | ||||||||||||||
| Water rights | indefinite | |||||||||||||
| $ | ||||||||||||||
As part of the acquisition, we recorded $256 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 value of the skilled assembled workforce of AMPAC. All of the goodwill recognized is part of the specialty materials segment, and none of the goodwill is deductible for income tax purposes.
The allocation of the purchase price of AMPAC to the tangible and intangible assets acquired and liabilities assumed was developed using estimates of fair value. Acquisition-related charges of $1 million consisted primarily of legal and professional fees and are included in selling, general, and administrative expenses in our Consolidated Statements of Income for the third quarter and nine months ended September 30, 2024.
We accounted for this acquisition 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 from the date of acquisition in our Consolidated Statements of Income as well as in the specialty materials segment in Note 4. These results include a charge related to the sale of finished goods inventory acquired, which was recorded at fair value on the acquisition date and sold to customers during 2024.
The following table presents the financial results in thousands for AMPAC from the date of acquisition through September 30, 2024 and for the third quarter ended September 30, 2024 (in thousands).

The following table presents our estimated unaudited pro forma consolidated results for the third quarter and nine months ended September 30, 2024, assuming the acquisition of AMPAC had occurred on January 1, 2023. The unaudited pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been realized if the acquisition had been completed at the beginning of 2023, nor is it indicative of expected results for any future period. In addition, no effect is given to any future synergistic benefits that could result from the integration of AMPAC into NewMarket.
Unaudited pro forma information for the third quarter and nine months ended September 30, 2024 includes adjustments to depreciation and amortization based upon the fair value allocation of the purchase price to AMPAC's tangible and intangible assets acquired and liabilities assumed as though the acquisition had occurred on January 1, 2023, as well as adjustments for debt-related costs and management fees. The acquisition-related costs and the charge related to the fair value adjustment to acquisition-date inventory were recognized in actual results during the third quarter and nine months ended September 30, 2024, but for the presentation below, these costs are excluded from 2024 unaudited pro forma income before income taxes since on a pro forma basis, they would have been incurred during 2023.

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. The sale of specialty materials products is predominantly to customers located in the United States. Our specialty materials customers are primarily contractors or subcontractors of 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 site.
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, 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.
The following table provides information on our net sales by geographic area. Information on net sales by segment is presented in Note 4.

4. 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. The petroleum additives and specialty materials segments are managed separately by the president of Afton and the president of AMPAC, 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 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 2024 Annual Report. NewMarket Services expenses are billed to Afton, AMPAC, and Ethyl 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 transfers occurred between any of the petroleum additives segment, specialty materials segment, and the “All other” category during the periods presented.

6. Earnings Per Share
We had 36,983 shares of nonvested restricted stock at September 30, 2025 and 34,474 shares of nonvested restricted stock at September 30, 2024 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.

Overview
When comparing the results of the petroleum additives segment for the first nine months of 2025 with the first nine months of 2024, net sales declined 3.1%, resulting primarily from lower product shipments, which were partially offset by favorable product mix. Petroleum additives operating profit decreased 9.4% when comparing the 2025 and 2024 nine months periods, primarily reflecting lower product shipments and higher operating costs, which were partially offset by lower raw material costs and favorable product mix. Operating profit was also unfavorably impacted for the nine months comparisons due to higher technology investments for research, development and testing during the 2025 period as compared to the 2024 period, as well as one-time charges related to network optimization efforts.
The specialty materials segment reported both higher net sales and higher operating profit for the first nine months of 2025 as compared to the same period in 2024, resulting primarily from higher product volumes. Specialty materials sales and operating profit for the first nine months of 2024 reflect financial results since the acquisition of AMPAC on January 16, 2024.
We continue to monitor the uncertain macroeconomic environment in which we operate, particularly the changes in international trade relations and tariffs, and assess the potential impacts to our operations. These impacts could include supply chain disruptions, lower customer demand, and higher inflation. Investing in technology to meet customer needs, enhancing our operational efficiency, and improving our portfolio profitability will remain priorities.
Despite the challenging economic environment, our financial position remains strong. We have sufficient access to capital, if needed, and do not anticipate any issues with meeting the covenants for all our debt agreements for the foreseeable future.
Our business typically generates significant amounts of cash beyond its operational needs. We continue to invest in and manage our business for the long-term with the goal of helping our customers succeed in their marketplaces. Our investments continue to be in organizational talent, technology development and processes, and global infrastructure.

Results of Operations
Net Sales
Consolidated net sales for the third quarter of 2025 totaled $690.3 million, representing a decrease of $34.6 million, or 4.8%, from the third quarter of 2024. Consolidated net sales for the first nine months of 2025 totaled $2.1 billion, representing a decrease of $42.1 million, or 2.0%, from the first nine months of 2024. The following table shows net sales by segment and product line. The net sales for the nine months 2024 period in the table below for the specialty materials segment include sales since the acquisition of AMPAC on January 16, 2024.

Petroleum Additives Segment
The regions in which we operate include North America, Latin America, Asia Pacific, and EMEAI. While there is some fluctuation, the percentage of net sales generated by region remained fairly consistent when comparing the first nine months of 2025 with both the same period in 2024, as well as with the full year of 2024.
Petroleum additives net sales for the third quarter of 2025 were $649.1 million compared to $663.0 million for the third quarter of 2024, a decrease of 2.1%. Decreases in Asia Pacific of 6.6% and North America of 5.2% were partially offset by an increase of 4.6% in EMEAI. Latin America was substantially unchanged when comparing the two periods.
Petroleum additives net sales for the first nine months of 2025 were $1.9 billion, a decrease of $61.6 million, or 3.1%, compared to the first nine months of 2024. Decreases in Asia Pacific of 9.1% and North America of 3.7% were partially offset by increases in EMEAI of 1.0% and Latin America of 0.5%.
The following table details the approximate components of the changes in petroleum additives net sales between the third quarter and first nine months of 2025 and 2024.

| Period ended September 30, 2025 | $ | 649.1 | $ | 1,948.5 | ||||||||||
When comparing the third quarters of 2025 and 2024, lower lubricant additives shipments drove the decrease in petroleum additives net sales, partially offset by an increase in fuel additives shipments. Selling prices for the third quarter comparison had a net unfavorable impact resulting primarily from an unfavorable product mix. When comparing the first nine months of 2025 and 2024, the decrease in petroleum additives net sales was due to lower product shipments in both lubricant additives and fuel additives. Partially offsetting these factors for the nine months comparison was favorable product mix.
The primary foreign currencies in which we transact include the Euro, Pound Sterling, Japanese Yen, Chinese Renminbi, and Indian Rupee. Comparing both the third quarter and nine months periods of 2025 and 2024, the United States Dollar strengthened against the Rupee and Renminbi and weakened against the Euro, Yen, and Pound Sterling, resulting in the favorable impacts to net sales shown in the table above.
21
On a worldwide basis, the volume of product shipments for petroleum additives decreased 4.1% when comparing the third quarter periods and 4.6% when comparing the nine months periods.
For the third quarter comparison, the decrease was in lubricant additives shipments, which was partially offset by a small increase in fuel additives shipments. Both the Asia Pacific and North America regions experienced decreases in lubricant additives shipments, along with a small decrease in the Latin America region. The EMEAI region reported a small increase in lubricant additives shipments. For the fuel additives third quarter comparison, the EMEAI, Latin America, and North America regions reported small increases in product shipments, while the Asia Pacific region was substantially unchanged.
For the nine months comparison, lower lubricant additives product shipments in the Asia Pacific and North America regions were partially offset by increases in the EMEAI and Latin American regions. For the fuel additives nine months comparison, both the EMEAI and North America regions reported decreases in product shipments, which were partially offset by increases in the Asia Pacific and Latin America regions.
Specialty Materials Segment
Total net sales for the specialty materials segment were $38.2 million for the third quarter of 2025 and $59.1 for the third quarter of 2024. For the nine months comparison, net sales were $134.0 million for 2025 and $114.2 million for the period that we owned AMPAC during 2024. The decrease in the third quarter comparison was primarily the result of timing of shipments when comparing the 2025 and 2024 periods, while the increase in net sales for the nine months comparison was primarily the result of higher product volumes.
All Other
The “All other” category includes the operations of the antiknock compounds business, as well as certain contracted manufacturing and related services associated with Ethyl.
Segment Operating Profit
NewMarket evaluates the performance of the petroleum additives and specialty materials businesses based on segment operating profit. NewMarket Services Corporation expenses are charged to NewMarket and each subsidiary pursuant to services agreements between the companies. Depreciation of segment property, plant, and equipment, as well as amortization of segment intangible assets and lease right-of-use assets, is included in segment operating profit.
The following table reports segment operating profit for the third quarter and nine months ended September 30, 2025 and September 30, 2024. The amount reported for specialty materials for the nine months ended September 30, 2024 is for the period from January 16, 2024 to September 30, 2024. A reconciliation of segment operating profit to income before income tax expense is in Note 4.

Petroleum Additives Segment
Petroleum additives segment gross profit decreased $21.9 million and operating profit decreased $26.2 million when comparing the third quarter of 2025 to the third quarter of 2024. For the first nine months of 2025 compared to the first nine months of 2024, petroleum additives segment gross profit decreased $31.3 million and operating profit decreased $43.0 million.
The decrease in both gross profit and operating profit for the third quarter comparison included the unfavorable impacts of higher operating costs, product mix, and lower product shipments, reflecting some softening in the market, as well as our portfolio profitability management and one-time charges related to network optimization efforts. These were partially offset by lower raw materials costs. For the nine months comparison, the drivers of the decrease in gross profit and operating profit were consistent with those of the third quarter comparison with the exception of a favorable product mix for the nine months comparison. Operating profit for both the third quarter and nine months comparison periods was also unfavorably impacted by higher technology investments for research, development and testing.

| Operating profit margin | 20.2 | % | 23.8 | % | 21.2 | % | 22.7 | % | ||||||||||||||||||
For the rolling four quarters ended September 30, 2025, the operating profit margin for petroleum additives was 21.3%, which is within our historical range of operating profit margin. While operating margins will fluctuate from quarter to quarter due to multiple factors, we believe the fundamentals of our business and industry as a whole are unchanged.
Petroleum additives selling, general, and administrative (SG&A) expenses for the third quarter of 2025 were $1.4 million higher than the third quarter of 2024 and $3.2 million higher for the first nine months of 2025 than the first nine months of 2024. SG&A expenses as a percentage of net sales were 5.1% for both the third quarter and nine months of 2025 and 4.8% for both the third quarter and nine months of 2024. Our SG&A costs are primarily personnel-related and include salaries, benefits, and other costs associated with our workforce, including travel-related expenses. While personnel-related costs fluctuate from period to period, there were no significant changes in the drivers of these costs when comparing the periods.
Our investments in petroleum additives research, development, and testing (R&D) increased $2.8 million when comparing the third quarters of 2025 and 2024 and $8.5 million when comparing the first nine months periods of 2025 and 2024. As a percentage of net sales, our R&D investment was 5.4% for the third quarter of 2025, 4.9% for the third quarter of 2024, 5.2% for the first nine months of 2025, and 4.6% for the first nine months of 2024. Our R&D investments reflect our efforts to support the development of solutions that meet our customers' needs, meet new and evolving standards, and support our expansion into new product areas. Our approach to R&D investments, as it is with SG&A costs, is one of purposeful spending on programs to support our current product base and to ensure that we develop products to support our customers' programs in the future. R&D investments include personnel-related costs, as well as costs for internal and external testing of our products.
Specialty Materials Segment
The specialty materials segment reported operating profit of $6.0 million for the third quarter of 2025 as compared to $16.0 million for the third quarter of 2024. For the first nine months of 2025, operating profit was $39.7 million as compared to operating profit of $16.0 million for the period from the AMPAC acquisition date of January 16, 2024 to September 30, 2024. The decrease in specialty materials operating profit for the third quarter comparison was primarily the result of timing of shipments, while the increase in specialty materials operating profit for the nine months comparison was primarily the result of higher product volumes.
The specialty materials results for the 2024 periods include the sale of AMPAC finished goods inventory that we acquired at closing. The acquired inventory was recorded at fair value on the acquisition date and sold during 2024, generating no margin.
We may experience substantial variation in quarterly results for the specialty materials segment on an ongoing basis due to the nature of its business.
The following discussion references certain captions on the Consolidated Statements of Income.
Interest and Financing Expenses, Net
Interest and financing expenses were $8.4 million for the third quarter of 2025, $14.2 million for the third quarter of 2024, $29.8 million for the first nine months of 2025, and $45.7 million for the first nine months of 2024.
The decrease for both the third quarter and nine months comparisons resulted primarily from lower average debt outstanding, along with a lower average interest rate.
Other Income (Expense), Net
Other income (expense), net was income of $13.3 million for the third quarter of 2025, $13.8 million for the third quarter of 2024, $43.5 million for the first nine months of 2025, and $38.3 million for the first nine months of 2024. The amounts for both the 2025 and 2024 third quarter and nine months periods primarily reflect the components of net periodic benefit cost (income), except for service cost, from defined benefit pension and postretirement plans. See Note 5 for further information on total periodic benefit cost (income).

Income Tax Expense
Income tax expense was $35.3 million for the third quarter of 2025 and $36.8 million for the third quarter of 2024. The effective tax rate was 26.1% for the third quarter of 2025 and 21.8% for the third quarter of 2024. Income tax expense decreased $7.3 million due to lower income, which was partially offset by an increase of $5.8 million resulting from the higher effective tax rate.
Income tax expense was $109.9 million for the first nine months of 2025 and $98.2 million for the first nine months of 2024. The effective tax rate was 24.6% for the first nine months of 2025 and 21.8% for the first nine months of 2024. Income tax expense increased $12.3 million due to the higher effective tax rate, which was slightly offset by lower income.
The increase in the tax rate for both periods was primarily driven by changes in estimates related to prior year taxes and income and withholding taxes on our foreign earnings.
On July 4, 2025, the One Big Beautiful Bill Act ("OBBBA") was enacted in the United States. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework, and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The 2025 impacts of the OBBBA have been recorded in the income tax provision for the third quarter and nine months ended September 30, 2025. These impacts were not material. We are continuing to assess the impact of the provisions of the OBBBA that are effective in future years.

Cash and cash equivalents at September 30, 2025 were $102.5 million, an increase of $25.0 million since December 31, 2024.
Cash and cash equivalents held by our foreign subsidiaries amounted to $96.2 million at September 30, 2025 and $71.3 million at December 31, 2024. Periodically, we repatriate cash from our foreign subsidiaries to the United States through intercompany dividends and loans. We do not anticipate significant tax consequences from future distributions of foreign earnings.
A portion of our foreign cash balances is associated with earnings that we have asserted are indefinitely reinvested. We plan to use these indefinitely reinvested earnings to support growth outside of the United States through funding of operating expenses, research and development expenses, capital expenditures, and other cash needs of our foreign subsidiaries.
We expect that cash from operations, together with borrowing available under our revolving credit facility, will continue to be sufficient to cover our operating needs including planned short-term and long-term capital expenditures.
Cash Flows – Operating Activities
Cash provided from operating activities for the first nine months of 2025 was $423.8 million, including $4.5 million of lower working capital requirements. The $4.5 million excluded an unfavorable foreign currency impact to the components of working capital on the balance sheet.
When comparing the September 30, 2025 balances with those at December 31, 2024, the most significant changes in working capital included increases in trade and other accounts receivable and accounts payable. The increase in trade and other accounts receivable primarily reflects higher sales during the third quarter of 2025 compared to the fourth quarter of 2024. The increase in accounts payable is primarily the result of increased purchases during the third quarter of 2025 and normal invoice payment timing.
Including cash and cash equivalents, as well as the impact of changes in foreign currency exchange rates on the balance sheet, we had total working capital of $690.7 million at September 30, 2025 and $655.1 million at December 31, 2024. The current ratio was 2.68 at September 30, 2025 and 2.75 at December 31, 2024.
Cash Flows – Investing Activities
Cash used in investing activities totaled $49.6 million during the first nine months of 2025, comprised of capital expenditures. We expect that our total capital spending during 2025 will be in the $70 million to $100 million range and will include improvements to our manufacturing and R&D infrastructure around the world.
Included in the expected capital expenditures for 2025 is a capital investment to expand AMPAC's ammonium perchlorate production capabilities in support of growing solid rocket motor demand. The project of up to $100 million is currently scheduled to be completed during 2026 and includes the construction of an additional production line, increasing capacity by more than 50%. The increased capacity will allow AMPAC to meet the anticipated future demand of U.S. military and space launch programs, while also addressing the needs of U.S. allies in these critical areas.
24
We expect to continue to finance capital spending through cash on hand and cash provided from operations, together with borrowing available under our revolving credit facility.
Cash Flows – Financing Activities
Cash used in financing activities during the first nine months of 2025 amounted to $350.1 million. These cash flows included principal payments of $150.0 million on the term loan and $50 million on the 3.78% senior notes, cash dividends of $77.7 million, and repurchases of our common stock of $77.2 million, which were partially offset by net borrowings of $11.0 million on the revolving credit facility.
Debt
Our long-term debt was $783.1 million at September 30, 2025 compared to $971.3 million at December 31, 2024.
See Note 9 for additional information on the 2.70% senior notes, 3.78% senior notes, term loan, and revolving credit facility, including the unused portion of our revolving credit facility.
All of our senior notes, the term loan, and the revolving credit facility contain covenants, representations, and events of default that management considers typical of credit arrangements of this nature. The covenants under the 3.78% senior notes, as well as the term loan, include negative covenants, certain financial covenants, and events of default which are substantially similar to the covenants and events of default in our revolving credit facility.
The revolving credit facility contains financial covenants that require NewMarket to maintain a consolidated Leverage Ratio (as defined in the agreement) of no more than 3.75 to 1.00, except during an Increased Leverage Period (as defined in the agreement) at the end of each quarter. At September 30, 2025, the Leverage Ratio was 1.10 under the revolving credit facility.
At September 30, 2025, we were in compliance with all covenants under the 3.78% senior notes, 2.70% senior notes, term loan, and revolving credit facility.
As a percentage of total capitalization (total long-term debt and shareholders’ equity), our total long-term debt decreased from 39.9% at December 31, 2024 to 31.7% at September 30, 2025. The change resulted from the increase in shareholders' equity along with a net decrease in outstanding long-term debt. The increase in shareholders’ equity primarily reflects our earnings and favorable impact from foreign currency translation adjustments, partially offset by repurchases of shares of our common stock and dividend payments. Generally, we repay any outstanding long-term debt with cash from operations or refinancing activities.
Critical Accounting Policies and Estimates
This Form 10-Q and our 2024 Annual Report include discussions of our accounting policies, as well as methods and estimates used in the preparation of our financial statements. We also provided a discussion of Critical Accounting Policies and Estimates in our 2024 Annual Report.
There have been no significant changes in our critical accounting policies and estimates from those reported in our 2024 Annual Report.

Outlook
Our goal is to provide a 10% compounded return per year for our shareholders over any ten-year period (defined as earnings per share growth plus dividend yield), although we may not necessarily achieve a 10% return each year. We continue to have confidence in our customer-focused strategy and approach to the market. We believe the fundamentals of how we run our business - a long-term view, safety-first culture, customer-focused solutions, technology-driven product offerings, and world-class supply chain capability - will continue to be beneficial for all of our stakeholders over the long term.
We expect our petroleum additives segment will continue to experience impacts to its operating performance during the remainder of 2025 due to market softness and the uncertain global economic environment in which we operate. Nonetheless, we anticipate continued solid results from this segment in 2025. We will continue to focus on cost control and operating profit margin management, while advancing our initiatives to build a global manufacturing network that will enable more efficient product delivery to our customers in the years ahead.
25
Over the past several years we have made significant investments in our petroleum additives business as the industry fundamentals remain positive. These investments have been, and will continue to be, focused on operational efficiencies, organizational talent, and technology development and processes, as well as global infrastructure, including technical centers, production capabilities and geographic expansion. We intend to utilize these investments to improve our ability to deliver the solutions that our customers value, expand our global reach, and enhance our operating results. We will continue to invest in our capabilities to provide even better value, service, technology, and customer solutions.
In addition to the ongoing investments we make in our petroleum additives business, we have, since 2024, completed the acquisition of two companies - AMPAC and Calca - which constitute our specialty materials segment. We continue to focus on the integration of these companies into our business, and we anticipate solid results from both companies. We may experience substantial variation in quarterly results for the specialty materials segment on an ongoing basis due to the nature of the business, including any impact from shutdowns of the U.S. government.
Our business typically generates significant amounts of cash beyond its operational needs. We regularly review our many internal opportunities to utilize excess cash from technological, geographic, production capability, and product line perspectives. We believe our capital spending is creating the capability we need to grow and support our customers worldwide, and our research and development investments are positioning us well to provide added value to our customers.
While our recent acquisitions of AMPAC and Calca were outside of our core petroleum additives business, we believe both presented an excellent opportunity to provide long-term value for our shareholders. Nonetheless, our primary focus in the acquisition area remains on the petroleum additives industry. It is our view that the petroleum additives industry will provide the greatest opportunity for solid returns on our investments while minimizing risk. We remain focused on this strategy and will evaluate any future opportunities. We will continue to evaluate all alternative uses of cash to enhance shareholder value, including stock repurchases and dividends.

At September 30, 2025, there were no material changes in our market risk from the information provided in the 2024 Annual Report.
ITEM 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
We maintain a system of internal control over financial reporting to provide reasonable, but not absolute, assurance of the reliability of the financial records and the protection of assets. Under Rule 13a-15(b) of the Securities Exchange Act of 1934 (the Exchange Act), we carried out an evaluation, with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) of the Exchange Act, as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level.
There has been no change in our internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act, which occurred during the quarter ended September 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
