NewMarket Corporation has announced the execution of a definitive purchase agreement to acquire Mars TopCo, LLC, the ultimate parent company of Calca Solutions, LLC. The acquisition adds a leading manufacturer of specialised chemicals to NewMarket’s portfolio while expanding the company’s presence in the defense and aerospace sectors.
Calca Solutions, currently a portfolio company of AE Industrial Partners, LP, operates as the leading U.S. manufacturer of UltraPure and high purity hydrazine—mission critical chemicals utilised across a wide range of applications. The Louisiana-based company has established itself as a key supplier to both government and commercial customers requiring the highest quality chemical products.

Strategic Market Position and Applications
Based in Lake Charles, Louisiana, Calca has developed particular expertise in producing chemicals essential for space applications. The company’s products serve as crucial components for in-space propulsion systems used by satellites, space probes, and other space vehicles, making it an integral part of the modern space economy.
The company has maintained a long-standing relationship with the Department of Defense, serving as a supplier to the Defense Logistics Agency – Energy for over 70 years. This extensive government partnership demonstrates Calca’s reliability and the critical nature of its products for national defense applications.
Beyond aerospace applications, Calca’s hydrazine derivatives serve vital functions in the manufacture of products across diverse industries, including agricultural, pharmaceutical, water treatment, and various industrial applications. This market diversification provides stability and growth opportunities across multiple sectors.
Strategic Fit with NewMarket’s Portfolio
The acquisition aligns with NewMarket’s strategic objectives for diversification and expansion into resilient market sectors. NewMarket, which has operated in manufacturing since 1887 and specialised in chemicals for nearly 100 years, brings extensive experience and resources to support Calca’s continued growth.
Thomas E. Gottwald, NewMarket’s chairman and CEO, emphasised the strategic value of the acquisition. “We are excited about the opportunity to acquire Calca and adding it to the NewMarket family. With skilled people and sustainable advantages in vital markets, it is a terrific fit with our acquisition and diversification criteria,” Gottwald stated.
Building Defense and Aerospace Capabilities
The Calca acquisition represents NewMarket’s second recent expansion into the defense and aerospace industries, reflecting the company’s strategic focus on these high-value market segments. Gottwald highlighted the company’s commitment to supporting customers across these critical sectors.
“Calca is our second recent acquisition in the defense and aerospace industries, and we intend to use our technological capability, financial strength, and ultra long-term investment horizon to be the right long-term partner for our defense, aerospace, and all other customers,” Gottwald explained.
This approach leverages NewMarket’s established capabilities in research, development, and testing to provide comprehensive solutions tailored to customer needs across multiple industries.
Company Heritage and Customer Focus
NewMarket emphasises its long-term commitment to its workforce, safety standards, innovative customer solutions, and social responsibility. The company’s extensive research, development, and testing expertise enables close collaboration with customers to deliver advanced products, comprehensive testing programmes, and superior technical solutions customised to individual requirements.
This customer-centric approach has supported NewMarket’s growth and market position across its nearly century-long presence in specialty chemicals, providing a foundation for integrating and growing acquired businesses like Calca.
Transaction Details and Timeline
The acquisition is scheduled to close in 2025, subject to satisfaction or waiver of customary closing conditions, including clearance under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. NewMarket plans to finance the acquisition using available cash reserves and borrowings under its existing revolving credit facility.
The transaction structure reflects NewMarket’s financial strength and ability to execute strategic acquisitions while maintaining operational flexibility for future growth initiatives.
The addition of Calca Solutions strengthens NewMarket’s position in mission critical chemicals while providing access to specialised markets where quality, reliability, and long-term partnerships are essential for success. The acquisition positions both companies to capitalise on growing demand for specialised chemicals across aerospace, defense, and industrial applications.
