Celsius Holdings reported that one out of every five energy drinks sold in the US during the first quarter of 2026 came from its portfolio, which includes the flagship Celsius brand, Alani Nu, and Rockstar Energy. The Boca Raton, Florida company posted record Q1 revenue of $782.6 million, a 138 percent increase year over year.
Alani Nu generated the largest share of that revenue at $368.1 million, followed by Celsius at $347.9 million and Rockstar at $66.6 million. CEO John Fieldly attributed the growth to the completion of Celsius Holdings' integration of Alani Nu into its business model, which enabled the company to capture $50 million in synergies between the two brands.
The company now holds an approximate 20.9 percent dollar share of the US energy drink category as of Q1 2026, according to Fieldly. This position was built on Celsius' 2025 acquisitions of Alani Nu and Rockstar. Celsius paid $1.8 billion for Alani Nu in April and expanded its distribution partnership with PepsiCo in September as part of the Rockstar deal. As PepsiCo's energy category captain in the US, Celsius benefits from the distributor's commercial alignment.
On the innovation front, Alani Nu's Lime Slush became the brand's top-selling flavor in tracked channels following its limited-time launch. Celsius' Fizz-Free non-carbonated lineup, meanwhile, is emerging as a meaningful growth platform. International expansion also gained momentum, with Celsius launching in Spain in March through an exclusive agreement with Suntory Beverage & Food Spain. International revenue reached $35.3 million in Q1, up 55 percent year over year, driven by growth in the Nordics and expansion markets including the UK, Ireland, France, Australia, and New Zealand. The company is now extending its partnership with Suntory to launch in Portugal.
