The company reports two main segments: petroleum additives, where Afton is a global supplier of lubricant and fuel additive packages, and specialty materials, which produces perchlorates and Ultra Pure® and high‑purity hydrazine for rockets, missiles, and satellite propulsion. It emphasizes heavy investment in R&D, intellectual property protection, and global manufacturing, with about 2,050 employees worldwide.
NewMarket highlights strong safety and environmental programs, including Responsible Care® certifications and a Vision of Zero injuries, with an injury/illness recordable rate of 1.10 in 2025 and $44 million spent on environmental operating and clean‑up costs. Capital returns include a share repurchase authorization of $500 million (with approximately $428 million remaining at year‑end 2025) and cash dividends of $11.25 per share in 2025, up from $10.00 per share in 2024.
NewMarket Corporation reported slightly lower results for 2025 after a record 2024, with net income of $418.7 million and earnings per share of $44.44, down from $462.4 million and $48.22. Management attributes most of the decline to a higher effective income tax rate.
The core petroleum additives segment generated $2.5 billion in sales and $520.1 million in operating profit, compared with $2.6 billion and $591.9 million in 2024, as shipments fell and pricing softened. In contrast, the specialty materials segment expanded, with sales rising to $182.5 million and operating profit to $47.0 million, helped by the AMPAC and Calca acquisitions.
Cash generation remained strong: NewMarket paid $105.9 million in dividends, repurchased $77.2 million of stock, funded $77.6 million of capital expenditures, invested over $200 million in the Calca acquisition, and still reduced long‑term debt by $87.9 million, ending 2025 with a Net Debt to EBITDA ratio of 1.1.
