Net Income of $118 million and Earnings per Share of $12.62
Segment Operating Profit of $147 million
Stock repurchases of $126 million

NewMarket Corporation (NYSE:NEU) Chairman and Chief Executive Officer, Thomas E. Gottwald, released the following earnings report of the Company's operations for the first quarter of 2026.

Net income for the first quarter of 2026 was $118.1 million, or $12.62 per share, compared to net income of $125.9 million, or $13.26 per share, for the first quarter of 2025.

Petroleum additives sales for the first quarter of 2026 were $609.8 million, compared to $645.6 million for the same period in 2025. Petroleum additives operating profit for the first quarter of 2026 was $135.0 million, compared to $142.1 million for the first quarter of 2025. The decrease in petroleum additives operating profit was primarily driven by a 7% decline in shipments between quarterly periods due to softness in the market and our strategic decision to examine and reduce low-margin business. The decline in shipments was mainly driven by lower lubricant additives shipments partially offset by an increase in fuel additives shipments. Despite the lower shipments, our operating profit margin for the first quarter of 2026 remained strong as a result of our continued focus on operational efficiency.

Specialty materials sales were $58.1 million for the first quarter of 2026, compared to $53.7 million for the first quarter of 2025. The increase in specialty materials sales is driven by the inclusion of the Calca Solutions, LLC (Calca) business that was acquired on October 1, 2025, partially offset by a shift in product shipment mix at American Pacific Corporation (AMPAC). Specialty materials operating profit was $12.4 million for the first quarter of 2026, compared to operating profit of $23.2 million for the first quarter of 2025. The decrease in specialty materials operating profit was primarily driven by a shift in quarterly product shipment mix at AMPAC. 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.

Our operations generated solid cash flows during the first quarter of 2026. We paid dividends of $28.0 million, repurchased over 200 thousand shares of common stock for $125.6 million, and funded capital expenditures of $24.4 million. 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 continue to monitor the impact of the conflict in the Middle East, the uncertain macroeconomic environment, and the changes in international trade relations and tariffs. Within petroleum additives, our team has acted rapidly to adjust prices to compensate for the expected escalation of costs for raw materials, utilities and logistics. We have also rebalanced our global production to assist in mitigating regional disruption for our customers, as the environment is dynamically evolving. We believe that these actions, together with positive shipment trends observed at the end of the first quarter of 2026, position us well to continue delivering solid results.

We are pleased with the performance of both our petroleum additives and specialty materials segments during the first quarter of 2026 and we anticipate continued solid results. 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.

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 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, net, income taxes, depreciation (on property, plant, and equipment) and amortization (on intangible assets 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.
