2025 Petroleum Additives Operating Profit of $520 Million
2025 Specialty Materials Operating Profit of $47 Million
2025 Net Income of $419 Million and Earnings per Share of $44.44
Strong Operating Cash Flows During the Year

NewMarket Corporation (NYSE:NEU) Chairman and Chief Executive Officer, Thomas E. Gottwald, released the following earnings report of the Company's operations for the fourth quarter and full year 2025.

Income before income tax expense for the fourth quarter of 2025 was $113.2 million compared to $134.2 million last year. For the full year 2025, income before income tax expense was $560.6 million compared to $584.1 million in 2024. Net income for the fourth quarter of 2025 was $81.3 million, or $8.65 per share, compared to net income of $110.7 million, or $11.56 per share, for the same period last year. For the full year 2025, net income was $418.7 million, or $44.44 per share, compared to $462.4 million, or $48.22 per share, for 2024, which was a record year. The decline in net income was mainly driven by a higher effective income tax rate in 2025 compared to 2024.

Petroleum additives sales for the fourth quarter of 2025 were $585.1 million, compared to $626.1 million for the same period in 2024. Petroleum additives operating profit for the fourth quarter of 2025 was $106.8 million, compared to $135.7 million for the fourth quarter of 2024. The decrease in petroleum additives operating profit was primarily driven by a 6 percent decline in shipments between quarterly periods as well as a decline in selling prices. In addition, to manage inventory levels, operating profit in the fourth quarter was impacted by higher unit costs resulting from lower production volumes at our plants. The decline in shipments was mainly driven by lower lubricant additives shipments, while fuel additives shipments were slightly higher compared to last year.

Petroleum additives sales were $2.5 billion for the full year 2025, compared to $2.6 billion in 2024. Petroleum additives operating profit for the full year 2025 was $520.1 million, compared to $591.9 million in 2024, which was an all time high for this segment. The drivers for the decrease in operating profit between these periods were consistent with those affecting the fourth quarter comparison discussed above, as well as one-time charges taken in the third quarter related to our efforts to become more efficient by optimizing our global manufacturing network and an increase in technology investments. Shipments decreased 4.9 percent when comparing the full year 2025 with 2024, driven by softness in the market and our strategic decision to examine and reduce low-margin business.

Specialty materials sales were $48.5 million for the fourth quarter of 2025, compared to $27.1 million for the fourth quarter of 2024. Specialty materials operating profit was $7.3 million for the fourth quarter of 2025, compared to operating profit of $1.5 million for the fourth quarter of 2024. The increase in specialty materials sales was primarily driven by increased volumes at American Pacific Corporation (AMPAC) and the inclusion of the Calca Solutions, LLC (Calca) business that was acquired on October 1, 2025. As previously stated, we expect variation in quarterly results for the specialty materials segment on an ongoing basis due to the nature of its business.

Specialty materials sales were $182.5 million for the full year 2025, compared to $141.2 million for the full year of 2024. Specialty materials operating profit for the full year 2025 was $47.0 million, compared to $17.5 million last year. Specialty materials sales and operating profit for the full year 2024 reflect financial results since the acquisition of AMPAC on January 16, 2024. Through our acquisitions of AMPAC and Calca and our investments to expand capacity at both operations, we have committed approximately $1 billion to this resilient, high-technology specialty materials segment.

Our operations generated solid cash flows during the full year 2025. We paid dividends of $105.9 million, repurchased common stock for $77.2 million, and funded capital expenditures of $77.6 million. Additionally, we reduced our long-term debt by $87.9 million during 2025 even after investing over $200 million in the Calca acquisition, driving our Net Debt to EBITDA ratio down to 1.1 as of December 31, 2025. The cash flows generated by operations enable us to continue to provide value to our shareholders through reinvestment in our businesses for growth and efficiency, acquisitions, share repurchases, and dividends.

We are pleased with the performance of both our petroleum additives and specialty materials segments during 2025. We are experiencing impacts to the petroleum additives segment due to market softness and the uncertain global economic environment in which we operate. Nonetheless, we anticipate continued solid results from this segment. We will continue to invest in technology to serve our customers, focus on cost control and margin management, and advance our initiatives to build a global manufacturing network that will enable more efficient product delivery to our customers in the years ahead. We are also excited about expanding production in the specialty materials segment to provide more capacity and a stronger supply chain for our customers, and we expect to see that capacity come online towards the end of 2026.

We continue to monitor the uncertain macroeconomic environment, particularly the changes in international trade relations and tariffs, and assess the potential impacts to our operations. Our dedicated team makes decisions to promote long-term value for our shareholders and customers, and remains focused on our long-term objectives. 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 our stakeholders.

Sincerely,

Thomas E. Gottwald

The specialty materials segment operates primarily in North America.

The Company has disclosed the non-GAAP financial measures EBITDA, Net Debt, and Net Debt to EBITDA, as well as the related calculations in the schedules included with this earnings release. EBITDA is defined as income from continuing operations before the deduction of interest and financing expenses, income taxes, depreciation (on property, plant, and equipment) and amortization (on intangibles and lease right-of-use assets). Net Debt is defined as long-term debt, including current maturities, less cash and cash equivalents. Net Debt to EBITDA is defined as Net Debt divided by EBITDA for the rolling four quarters ended as of the specified date. The Company believes that even though these items are not required by or presented in accordance with United States generally accepted accounting principles (GAAP), these additional measures enhance understanding of the Company's performance and period to period comparability. The Company believes that these items should not be considered an alternative to our results determined under GAAP.
