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

Net income for the third quarter of 2025 was $100.3 million, or $10.67 per share, compared to net income of $132.3 million, or $13.79 per share, for the same period last year. For the first nine months of 2025, net income was $337.5 million, or $35.78 per share, compared to $351.7 million, or $36.66 per share, for the same period in 2024.

Petroleum additives sales for the third quarter of 2025 were $649.1 million, compared to $663.0 million for the same period in 2024. Petroleum additives operating profit for the third quarter of 2025 was $131.3 million, compared to $157.5 million for the third quarter of 2024, which was a record quarter for this segment. The decrease in petroleum additives operating profit was primarily driven by one-time charges during the quarter, including those related to optimizing our global manufacturing network to become more efficient. A 4.1% decline in shipments between quarterly periods and an increase in technology investments also contributed to the decrease in petroleum additives operating profit. The decline in shipments was mainly driven by lubricant additives shipments, partially offset by an increase in fuel additives shipments.

Petroleum additives sales were $1.9 billion for the first nine months of 2025, compared to $2.0 billion for the same period in 2024. Petroleum additives operating profit for the first nine months of 2025 was $413.2 million, compared to $456.2 million in the same period last year. The drivers for the decrease in operating profit between these periods were consistent with those affecting the third quarter comparison discussed above. Shipments decreased 4.6% when comparing the first nine months of 2025 with the same period in 2024, driven by softness in the market and our strategic decision to examine and reduce low-margin business.

Specialty materials sales were $38.2 million for the third quarter of 2025, compared to $59.1 million for the third quarter of 2024. Specialty materials operating profit was $6.0 million for the third quarter of 2025, compared to operating profit of $16.0 million for the third quarter of 2024. The decrease in specialty materials operating profit was primarily driven by decreased volumes. As previously stated, we will see substantial variation in quarterly results for the specialty materials segment on an ongoing basis due to the nature of its business.

Specialty materials sales were $133.9 million for the first nine months of 2025, compared to $114.2 million for the first nine months of 2024. Specialty materials operating profit for the first nine months of 2025 was $39.7 million, compared to $16.0 million in the same period last year. Specialty materials sales and operating profit for the first nine months of 2024 reflect financial results since the acquisition of American Pacific Corporation (AMPAC) on January 16, 2024.

As previously announced, we expanded our investment in the specialty materials segment through the October 1, 2025 acquisition of Calca Solutions, LLC (Calca). Calca is the nation's leading producer of UltraPure and high-purity hydrazine, mission-critical propellants used in advanced aerospace and defense applications. Since 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 first nine months of 2025. We paid dividends of $77.7 million, repurchased common stock for $77.2 million, and funded capital expenditures of $49.6 million. Additionally, we reduced our long-term debt by $188.2 million (Net Debt by $213.2 million) during the first nine months of 2025, driving our Net Debt to EBITDA ratio down to 0.9 as of September 30, 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. Earlier today, the Company's Board of Directors approved raising the quarterly dividend 9% from $2.75 per share on our common stock to $3.00 per share for the dividend that is payable January 2, 2026.

We are pleased with the performance of both our petroleum additives and specialty materials segments during the first nine months of 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 focus on cost control and 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. 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 in the second half 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 to EBITDA is defined as Net Debt divided by EBITDA for the rolling four quarters ended as of the specified date.
