NewMarket Corporation announced its entry into a definitive purchase agreement to acquire Mars TopCo, LLC, the parent company of Calca Solutions, LLC (Calca). Calca is a leading U.S. manufacturer of UltraPure and high purity hydrazine, chemicals essential for various applications.
Calca's products are notably utilized for in-space propulsion by satellites, space probes, and other space vehicles, and the company has supplied high purity hydrazine to the Department of Defense’s Defense Logistics Agency – Energy for over 70 years. Beyond aerospace, Calca's hydrazine derivatives are used in agricultural, pharmaceutical, water treatment, and industrial applications.
This acquisition strengthens NewMarket’s position in mission-critical chemicals and expands its presence in resilient market sectors, building on its recent diversification into defense and aerospace. The transaction is expected to close in 2025, subject to customary closing conditions, including antitrust clearance, and will be financed with available cash and revolving credit facility borrowings.
