NewMarket to acquire additives maker American Pacific for $700 million

NewMarket Corporation announced its entry into a definitive purchase agreement to acquire AMPAC Intermediate Holdings, LLC, the ultimate parent company of American Pacific Corporation (AMPAC), for approximately $700 million. 

Based in Cedar City, Utah, AMPAC is the leading North American manufacturer of critical performance additives used in solid rocket motors for space launch and military defense applications. AMPAC is qualified on many NASA and Department of Defense programs, and has been serving space launch and national defense programs for more than 60 years. AMPAC also manufactures Halotron BrX, a clean and environmentally friendly fire extinguishing agent that replaces legacy high ozone-depleting fire extinguishing agents. Founded in 1955, AMPAC has one operating facility and approximately 150 full-time employees. The acquisition of AMPAC expands NewMarket’s exposure to mission critical, resilient sectors. 

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 excited about the opportunity to acquire AMPAC. With consistent cash generation, sustainable competitive advantages in vital markets, and an experienced management team, it is a terrific fit with our acquisition and diversification criteria. We view AMPAC as a strategic, national asset with a mission-critical role in global safety, security, and space programs, and we believe NewMarket is the right long-term owner for this essential business. We look forward to welcoming the entire AMPAC team into the NewMarket family.” 

The transaction is expected to close during the first quarter of 2024. 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.
