NewMarket Corporation announced its entry into a definitive purchase agreement to acquire Mars TopCo, the ultimate parent company of Calca Solutions. Calca is currently a portfolio company of AE Industrial Partners, LP.

Based in Lake Charles, Louisiana, Calca is the leading U.S. manufacturer of UltraPure and high purity hydrazine – mission critical chemicals used in a wide range of applications. These products are utilized for in-space propulsion by satellites, space probes and other space vehicles.

The acquisition of Calca strengthens NewMarket’s position in mission critical chemicals while expanding its presence in resilient market sectors.

The transaction is expected to close in 2025. The closing is conditioned upon the satisfaction or waiver of customary closing conditions, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. NewMarket expects to finance the acquisition with available cash and borrowings under its revolving credit facility.
