The private equity firm AE Industrial Partners (AEI) last Thursday said it has acquired specialty chemicals manufacturer American Pacific Corporation, which services the defense, space, pharmaceutical and fire suppression markets.

Terms of the deal were not disclosed.

American Pacific, which was owned by Huntsman Family Investments, provides specialty chemicals used in solid rocket motors for space launch and military missiles. On its website, American Pacific says its products are typically sold through long-term contracts and it has established long-term strategic relationships with its customers.

“As a vital manufacturer of oxidizers for solid rocket propellant, American Pacific is uniquely positioned to support its customers with key initiatives in hypersonics, space launch, and military defense systems,” Trey Bivins, vice president at AEI, said in a statement. “AEI will continue to invest in American Pacific’s leading capabilities in this next chapter of growth to even better serve its customers.”

Huntsman Family Investments acquired American Pacific in 2015 from H.I.G. Capital. The investment firm is the office for the family of Jon M. Huntsman, Sr., the deceased American businessman.

American Pacific’s financial adviser on the deal was Houlihan Lokey and AEI was advised by PricewaterhouseCoopers.

American Pacific is based in Utah.
