Energy-drink maker Celsius Holdings Inc. lined up a $1 billion debt package to support its acquisition of Alani Nutrition LLC, a female-focused wellness company operated by Congo Brands.

UBS Group AG is leading the financing, which consists of a $900 million term loan, as well as a $100 million revolving credit facility, according to a statement Thursday. The $1.8 billion cash-and-stock acquisition will combine two names in what Celsius CEO John Fieldly describes as the “better-for-you” movement.
