Specialty materials delivered strong growth, with Q2 sales of $67.2 million and operating profit of $22.3 million. Robust first half cash generation funded $51.7 million of capital spending, $55.6 million of dividends, and $126.4 million of share repurchases, while Net Debt to EBITDA improved to 1.0x.

Petroleum additives net sales were $609.8 million with operating profit of $135.0 million, down from $645.6 million and $142.1 million, mainly due to a 7% shipment decline from softer markets and reduced low‑margin business. Specialty materials sales rose to $58.1 million from $53.7 million, helped by the Calca acquisition, but operating profit declined to $12.4 million from $23.2 million on less favorable mix.
Operating cash flow supported $28.0 million in dividends, $125.6 million of share repurchases (over 200,000 shares), and $24.4 million of capital spending. Net debt was $866.5 million, and rolling four‑quarter EBITDA was $709.7 million, resulting in net debt to EBITDA of 1.2.

NewMarket Corporation reported that its Board of Directors elected Bruce R. Hazelgrove, III as a director effective immediately. Hazelgrove currently serves as Executive Vice President and Chief Administrative Officer of the company, so he will not be considered an independent director.
He will serve on the Board’s Executive Committee but will not sit on other Board committees because of his officer role.

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.
