**NEWMARKET CORPORATION AND SUBSIDIARIES**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

(Unaudited)

**1.&nbsp;&nbsp;&nbsp;&nbsp;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, 2025 and December 31, 2024, our consolidated results of operations, comprehensive income, and changes in shareholders' equity for the second quarter and six months ended June 30, 2025 and June 30, 2024, and our cash flows for the six months ended June 30, 2025 and June 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 six-month period ended June 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.

*<u>Supplier Finance Program</u>*

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, 2025 and December 31, 2024, the amount of confirmed invoices under the supplier finance program was not material.

**2.&nbsp;&nbsp;&nbsp;&nbsp;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 | $16 |
| Trade and other accounts receivable, net | 6 |
| Inventories | 25 |
| Prepaid expenses and other current assets | 3 |
| Property, plant, and equipment, net | 111 |
| Intangibles and goodwill | 650 |
| Deferred charges and other assets | 5 |
| Accounts payable | (3) |
| Accrued expenses | (5) |
| Other noncurrent liabilities | (111) |
| Fair value of net assets acquired | $697 |

(Unaudited)

Identified intangible assets acquired consisted of the following (in millions):

---

| | | |
|:---|:---|:---|
| | **Fair Value** | **Estimated Useful Lives (in years)** |
| Customer base | $275 | 17.5 |
| Formulas and technology | 60 | 8 |
| Trademarks and trade names | 30 | 15 |
| Water rights | 29 | indefinite |
|  | $394 |  |

---

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 second quarter and six months ended June 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 June 30, 2024 and for the second quarter ended June 30, 2024 (in thousands).

|:---|:---|:---|
| **AMPAC** | **Second Quarter Ended June 30, 2024** | **January 16 to <br>June 30, 2024** |
| Net sales | $38010 | $55057 |
| Income (loss) before income taxes | 4923 | (78) |

The following table presents our estimated unaudited pro forma consolidated results for the second quarter and six months ended June 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 second quarter and six months ended June 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 second quarter and six months ended June 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.&nbsp;&nbsp;&nbsp;&nbsp;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, with limited amounts to customers in other countries. 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 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 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.

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, 2025 and June 30, 2024. No single customer accounted for 10% or more of our total net sales in any period presented.

**6.&nbsp;&nbsp;&nbsp;&nbsp;Earnings Per Share**

We had 37,202 shares of nonvested restricted stock at June 30, 2025 and 34,538 shares of nonvested restricted stock at June 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.

Of the total intangibles (net of amortization) and goodwill, $125 million is attributable to the petroleum additives segment and $613 million is attributable to the specialty materials segment. The change in the gross carrying amount between December 31, 2024 and June 30, 2025 is due to the foreign currency fluctuation on goodwill in the petroleum additives segment. See Note 2 for further information on the intangibles and goodwill obtained with the AMPAC acquisition. There is no accumulated goodwill impairment.

*<u>Senior Notes</u>* - The 2.70% senior notes, which were issued in 2021, are unsecured with an aggregate principal amount of $400 million. The offer and sale of the notes were registered under the Securities Act of 1933, as amended.

The 3.78% senior notes are unsecured and were issued in a 2017 private placement with The Prudential Insurance Company of America and certain other purchasers. We made the first principal payment of $50 million on January 4, 2025 and have four remaining principal payments of $50 million due January 4 of each year through 2029.

We were in compliance with all covenants under all issuances of senior notes as of June 30, 2025 and December 31, 2024.

*<u>Term Loan Credit Agreement</u>* - The term loan credit agreement is unsecured, has a borrowing capacity of $250 million, a term of two years, and matures on January 22, 2026. We borrowed the entire $250 million available under the term loan credit agreement and are required to repay the principal amount borrowed under the term loan in full at maturity. We may, in our sole discretion and subject to the conditions set forth in the term loan credit agreement, prepay amounts borrowed under the term loan, together with any accrued and unpaid interest, prior to maturity. Any amounts prepaid prior to maturity are not available for additional borrowings by NewMarket. We repaid $50 million on the term loan credit agreement during the second quarter of 2025.

We were in compliance with all covenants under the term loan credit agreement as of June 30, 2025 and December 31, 2024.

*<u>Revolving Credit Facility</u>* - The revolving credit facility has a borrowing capacity of $900 million, a term of five years, and matures on January 22, 2029. The obligations under the revolving credit facility are unsecured. The average interest rate for borrowings under the revolving credit agreement was 5.6% during the first six months of 2025 and 6.5% during the year ended December 31, 2024.

Outstanding borrowings under the revolving credit facility amounted to $47 million at June 30, 2025 and $77 million at December 31, 2024. Outstanding letters of credit amounted to approximately $4 million at both June 30, 2025 and December 31, 2024. The unused portion of the revolving credit facility amounted to $849 million at June 30, 2025 and $819 million at December 31, 2024.

We were in compliance with all covenants under the revolving credit facility as of June 30, 2025 and December 31, 2024.

**10.&nbsp;&nbsp;&nbsp;&nbsp;Commitments and Contingencies**

*<u>Legal Matters</u>*

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.

*<u>Environmental</u>*

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 $11 million at both June 30, 2025 and December 31, 2024. 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 $8 million of the total accrual above at June 30, 2025 and $9 million at December 31, 2024, using discount rates ranging from 3% to 9% for both periods. The aggregate undiscounted amount for these sites was $10 million at June 30, 2025 and $11 million at December 31, 2024.

*<u>Leases</u>*

At June 30, 2025, we had commitments of approximately $4 million for finance leases that have not yet commenced.

 **13.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Recent Accounting Pronouncements**

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" (ASU 2023-09). The FASB issued ASU 2023-09 to enhance the transparency and decision-making usefulness of income tax disclosures by requiring additional information on an entity's tax rate reconciliation, as well as income taxes paid. ASU 2023-09 was effective for our annual reporting period beginning January 1, 2025. The required disclosures will be included in our 2025 Annual Report on Form 10-K.

In November 2024, the FASB issued Accounting Standards Update No. 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" (ASU 2024-03). The FASB issued ASU 2024-03 to improve disclosures surrounding expenses in commonly presented captions including Cost of goods sold; Selling, general, and administrative expenses; and Research, development, and testing expenses. The additional expense information required to be disclosed includes purchases of inventory, employee compensation, depreciation, intangible assets amortization, and total selling expenses, as well as a qualitative description of amounts remaining that have not been separately presented. ASU 2024-03 is effective for our annual reporting period beginning January 1, 2027, and our quarterly reporting periods beginning January 1, 2028. Early adoption is permitted. We are currently assessing the impact that the adoption of ASU 2024-03 will have on the disclosures in our consolidated financial statements.

**<u>Overview</u>**

When comparing the results of the petroleum additives segment for the first six months of 2025 with the first six months of 2024, net sales declined 3.5%, resulting primarily from lower product shipments, which were partially offset by favorable product mix. Petroleum additives operating profit decreased 5.6% when comparing the 2025 and 2024 six 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 six months comparisons due to higher technology investments for research, development and testing during the 2025 period as compared to the 2024 period.

The specialty materials segment reported both higher net sales and higher operating profit for the first six 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 six 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 throughout 2025.

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.

<u>Petroleum Additives Segment</u>

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 six 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 second quarter of 2025 were $653.9 million compared to $669.8 million for the second quarter of 2024, a decrease of 2.4%. Decreases in Asia Pacific of 11.9% and North America of 3.5% were partially offset by increases of 4.5% in EMEAI and 2.5% in Latin America.

Petroleum additives net sales for the first six months of 2025 were $1.3 billion, a decrease of $47.7 million, or 3.5%, compared to the first six months of 2024. Asia Pacific decreased 10.2%, North America decreased 2.9%, EMEAI decreased 0.8%, and Latin America increased 0.8%.

The following table details the approximate components of the changes in petroleum additives net sales between the second quarter and first six months of 2025 and 2024.

---

When comparing the second quarters of 2025 and 2024, lower lubricant additives shipments drove the decrease in petroleum additives net sales. When comparing the first six months of 2025 and 2024, the decrease in petroleum additives net sales was due to lower product shipments, along with an unfavorable foreign currency impact. Partially offsetting these factors for the six months comparison was an increase to net sales driven by favorable product mix.

The primary foreign currencies in which we transact include the Euro, Pound Sterling, Japanese Yen, Chinese Renminbi, and Indian Rupee. Comparing the second quarters 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 small favorable impact to net sales in the table above. For the six months comparison, the United States Dollar strengthened against all of the major currencies in which we transact, except the Yen and Pound Sterling, resulting in the unfavorable impact to net sales for the six months comparison.

<u>[**Table of Contents**](#i96d275a5670c439f9419689f2707aed6_7)</u>&nbsp;&nbsp;&nbsp;&nbsp;

On a worldwide basis, the volume of product shipments for petroleum additives decreased 2.5% when comparing the second quarter periods and 4.9% when comparing the six months periods.

For the second 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, while the EMEAI and Latin America regions reported small increases in lubricant additives shipments. For the fuel additives second quarter comparison, both the Asia Pacific and Latin America regions reported increases in product shipments, which were partially offset by decreases in the EMEAI and North America regions.

For the six months comparison, lubricant additives product shipments were lower in the Asia Pacific and North America regions, which were partially offset by increases in the EMEAI and Latin American regions. For the fuel additives six 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.

<u>Specialty Materials Segment</u>

Total net sales for the specialty materials segment were $42.0 million for the second quarter of 2025 and $38.0 for the second quarter of 2024. For the six months comparison, net sales were $95.8 million for 2025 and $55.1 million for the period that we owned AMPAC during 2024. The increase in net sales for the second quarter and six months comparisons was primarily the result of higher product volumes.

<u>All Other</u>

The "All other" category includes the operations of the antiknock compounds business, as well as certain contracted manufacturing and related services associated with Ethyl.

***<u>Segment Operating Profit</u>***

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 second quarter and six months ended June 30, 2025 and June 30, 2024. The amount reported for specialty materials for the six months ended June 30, 2024 is for the period from January 16, 2024 to June 30, 2024. A reconciliation of segment operating profit to income before income tax expense is in Note 4.

<u>Petroleum Additives Segment</u>

Petroleum additives segment gross profit decreased $2.8 million and operating profit decreased $8.0 million when comparing the second quarter of 2025 to the second quarter of 2024. For the first six months of 2025 compared to the first six months of 2024, petroleum additives segment gross profit decreased $9.3 million and operating profit decreased $16.8 million.

The decrease in both gross profit and operating profit for both the second quarter and six months comparisons included the unfavorable impacts of lower product shipments and higher operating costs, which were partially offset by favorable product mix and lower raw material costs. Operating profit was also unfavorably impacted by higher technology investments for research, development and testing during both the 2025 second quarter and six months periods than during the same 2024 periods.

The following table presents petroleum additives cost of goods sold as a percentage of net sales and the operating profit margin.

---

For the rolling four quarters ended June 30, 2025, the operating profit margin for petroleum additives was 22.2%, 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 second quarter of 2025 were $1.5 million higher than the second quarter of 2024 and $1.8 million higher for the first six months of 2025 than the first six months of 2024. SG&A expenses as a percentage of net sales were 5.1% for the second quarter of 2025, 4.7% for the second quarter of 2024, 5.1% for the first six months of 2025, and 4.7% for the first six 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 investment in petroleum additives research, development, and testing (R&D) increased $3.7 million when comparing the second quarters of 2025 and 2024 and $5.7 million when comparing the first six months periods of 2025 and 2024. As a percentage of net sales, our R&D investment was 5.0% for the second quarter of 2025, 4.3% for the second quarter of 2024, 5.0% for the first six months of 2025, and 4.4% for the first six 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.

<u>Specialty Materials Segment</u>

The specialty materials segment reported operating profit of $10.5 million for the second quarter of 2025 as compared to $5.0 million for the second quarter of 2024. For the first six months of 2025, operating profit was $33.7 million as compared to operating profit of $5 thousand for the period from the AMPAC acquisition date of January 16, 2024 to June 30, 2024. The increase in specialty materials operating profit 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.*

***<u>Interest and Financing Expenses, Net</u>***

Interest and financing expenses were $10.7 million for the second quarter of 2025, $15.9 million for the second quarter of 2024, $21.4 million for the first six months of 2025, and $31.6 million for the first six months of 2024.

The decrease for both the second quarter and six months comparisons resulted primarily from lower average debt outstanding, along with a lower average interest rate.

***<u>Other Income (Expense), Net</u>***

Other income (expense), net was income of $15.3 million for the second quarter of 2025, $12.0 million for the second quarter of 2024, $30.2 million for the first six months of 2025, and $24.5 million for the first six months of 2024. The amounts for both the 2025 and 2024 second quarter and six 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).

<u>[**Table of Contents**](#i96d275a5670c439f9419689f2707aed6_7)</u>&nbsp;&nbsp;&nbsp;&nbsp;

***<u>Income Tax Expense</u>***

Income tax expense was $36.4 million for the second quarter of 2025 and $31.4 million for the second quarter of 2024. The effective tax rate was 24.7% for the second quarter of 2025 and 21.9% for the second quarter of 2024. Income tax expense increased $4.0 million due to the higher effective tax rate and $1.0 million due to higher income before income tax expense.

Income tax expense was $74.6 million for the first six months of 2025 and $61.3 million for the first six months of 2024. The effective tax rate was 23.9% for the first six months of 2025 and 21.9% for the first six months of 2024. Income tax expense increased $6.8 million due to higher income before income tax expense and $6.5 million due to the higher effective tax rate.

The increase in the tax rate for both periods was primarily driven by income from our foreign operations.

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. We are currently assessing the impact of the OBBBA on our consolidated financial statements.

**<u>Cash Flows, Financial Condition, and Liquidity</u>**

Cash and cash equivalents at June 30, 2025 were $70.3 million, a decrease of $7.2 million since December 31, 2024.

Cash and cash equivalents held by our foreign subsidiaries amounted to $66.3 million at June 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.

<u>Cash Flows – Operating Activities</u>

Cash provided from operating activities for the first six months of 2025 was $281.4 million, including $0.8 million of higher working capital requirements. The $0.8 million excluded an unfavorable foreign currency impact to the components of working capital on the balance sheet.

When comparing the June 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 second quarter of 2025 compared to the fourth quarter of 2024. The increase in accounts payable is primarily the result of increased purchases during the second 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 $665.7 million at June 30, 2025 and $655.1 million at December 31, 2024. The current ratio was 2.66 at June 30, 2025 and 2.75 at December 31, 2024.

<u>Cash Flows – Investing Activities</u>

Cash used in investing activities totaled $29.3 million during the first six 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 of up to $100 million to expand AMPAC's ammonium perchlorate production capabilities in support of growing solid rocket motor demand. This investment will include the construction of an additional production line, increasing capacity by more than 50%. The increased capacity will allow AMPAC to meet the demand of U.S. military and space launch programs, while also addressing the needs of U.S. allies in these critical areas. The project is currently scheduled to be completed during 2026.

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.

<u>[**Table of Contents**](#i96d275a5670c439f9419689f2707aed6_7)</u>&nbsp;&nbsp;&nbsp;&nbsp;

<u>Cash Flows – Financing Activities</u>

Cash used in financing activities during the first six months of 2025 amounted to $264.2 million. These cash flows included repurchases of our common stock of $77.2 million, cash dividends of $51.9 million, principal payments of $50.0 million each on the 3.78% senior notes and term loan, and net repayments of $30 million on the revolving credit facility.

<u>Debt</u> 

Our long-term debt was $841.8 million at June 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 June 30, 2025, the Leverage Ratio was 1.13 under the revolving credit facility.

At June 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 34.3% at June 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.

**<u>Critical Accounting Policies and Estimates</u>**

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.

**<u>Recent Accounting Pronouncements</u>**

For a full discussion of the more significant recently issued accounting standards, see Note 13.

**<u>Outlook</u>**

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.

Our petroleum additives segment may experience impacts to its operating performance during 2025 due to the uncertain global economic environment in which we operate; however, we anticipate continued strength from this segment. As a result, we will continue to focus on cost control and operating profit margin management throughout the year. We expect over the long-term that the petroleum additives market will grow annually up to 2%. We plan to exceed that growth rate in our petroleum additives segment.

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

------

<u>[**Table of Contents**](#i96d275a5670c439f9419689f2707aed6_7)</u>&nbsp;&nbsp;&nbsp;&nbsp;

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.

We continue to focus on the ongoing integration of AMPAC into our business. While we may experience substantial variation in quarterly results for specialty materials on an ongoing basis due to the nature of its business, we anticipate full year results to be consistent with our pre-acquisition expectations. Our planned investment to expand capacity at AMPAC is aligned with anticipated future industry demand.

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 AMPAC acquisition was outside of our core petroleum additives business, we believe it 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.
