RICHMOND, Va.--(BUSINESS WIRE)--

NewMarket Corporation ( NEU ) today announced that it has completed the acquisition of Mars TopCo, LLC, the ultimate parent company of Calca Solutions, LLC (Calca). Calca was previously a portfolio company of AE Industrial Partners, LP.

Headquartered in Lake Charles, Louisiana, Calca is the nation’s leading producer of UltraPure and high-purity hydrazine – essential, mission-critical propellants that enable advanced aerospace and defense applications. Calca’s products are integral to in-space propulsion systems for satellites, space probes, and other vehicles that operate in the most demanding environments. For more than 70 years, Calca has been the trusted supplier of high-purity hydrazine to the U.S. Department of Defense’s Defense Logistics Agency – Energy.

With a team of approximately 30 employees and annual revenue of less than $100 million, Calca combines expert technical know-how with a proven legacy of reliability, safety, and performance. This acquisition strengthens NewMarket’s strategic investment in resilient, high-technology sectors that demand quality and innovation.

NewMarket has been in the manufacturing industry since 1887 and has been in the specialty chemicals business for nearly 100 years. Our company has a long-term commitment to its people, to safety, to providing innovative solutions for our customers, and to making the world a better place. With extensive research, development and testing expertise, we collaborate with our customers to provide the most advanced products, comprehensive testing programs, and superior technical solutions tailored to their individual needs.

Thomas E. Gottwald, NewMarket’s Chairman and CEO, said: “We are very excited about closing the acquisition of Calca and would like to welcome the entire Calca team into the NewMarket family. We look forward to working with them and growing together. While we remain focused on our core petroleum additives business, since 2024, through our acquisitions of American Pacific Corporation (AMPAC) and Calca and our investments to expand capacity at both operations, we have committed approximately $1 billion in pursuing our acquisition and diversification strategies.”

The acquisition closed on October 1, 2025, and was funded by cash on hand and borrowings under our revolving credit facility. Calca will be managed as a separate business within our specialty materials segment. We believe Calca will be accretive to net income in 2026.

In addition to the acquired Calca business, NewMarket Corporation ( NEU ) is a holding company operating through its subsidiaries, Afton Chemical Corporation (Afton), Ethyl Corporation (Ethyl), and AMPAC. The Afton and Ethyl companies develop, manufacture, blend, and deliver chemical additives that enhance the performance of petroleum products. AMPAC is a manufacturer of specialty materials primarily used in solid rocket motors for the aerospace and defense industries. The NewMarket family of companies has a long-term commitment to its people, to safety, to providing innovative solutions for its customers, and to making the world a better place.
