NewMarket Corporation (NYSE: NEU) is a global specialty chemicals holding company primarily focused on the petroleum additives market. The company's core business is conducted through its principal subsidiaries, Afton Chemical Corporation and Ethyl Corporation, which develop, manufacture, blend, and deliver chemical additives that enhance the performance of fuels and lubricants. These products include engine oil additives for passenger cars and heavy-duty commercial equipment, driveline additives for transmission and axle fluids, and industrial additives for hydraulic fluids and turbine oils. In 2024, NewMarket diversified its operations by establishing a specialty materials segment following the acquisition of American Pacific Corporation (AMPAC), a manufacturer of specialty materials used in solid rocket motors for the aerospace and defense industries. This segment was further expanded with the acquisition of Calca Solutions, a producer of high-purity hydrazine propellants. Geographically, NewMarket has a global footprint, with North America accounting for approximately 40% of its petroleum additives net sales, followed by the EMEAI region (Europe, Middle East, Africa, and India) at roughly 30%, Asia Pacific at 20%, and Latin America making up the remainder. The company's competitive position is supported by its long-standing industry presence, extensive research and development capabilities, and strategic acquisitions aimed at diversifying into high-technology, mission-critical sectors.
