Celsius Q1 Hit $783M and +138% Growth. PepsiCo's 11% Stake Just Outperformed the Rest of Its Beverage Portfolio.

One in five energy drinks sold in the United States in the first quarter of 2026 came out of a single portfolio. That portfolio belongs to Celsius Holdings — a company that did less than $80 million in revenue six years ago and has just reported a record $782.6 million quarter, up 138% year-on-year.

The Q1 2026 print, released after market close on May 7, did three things at once. It validated PepsiCo's decision to lift its equity stake in Celsius from 8.5% to 11% in the August 2025 restructuring. It confirmed that the Alani Nu integration is delivering the $50 million in synergies management promised. And it exposed an uncomfortable contrast at the top of US beverage: PepsiCo's own North American beverage volumes fell 2.5% in Q1, while the brand it distributes — and partly owns — grew triple digits.

The numbers are the story

Celsius reported Q1 2026 revenue of $782.6 million, a 138% increase. Adjusted EPS came in at $0.41 versus $0.30 consensus, a 37% beat. Net income more than doubled to $110.1 million. Adjusted EBITDA reached $195.5 million at a 25.0% margin — confirming that the growth is not coming at the expense of unit economics.

Brand-level disclosure makes the picture sharper. Alani Nu contributed approximately $368.1 million of Q1 revenue, with retail sales up 100.0% year-on-year for the 13-week period ended March 29, 2026. The legacy Celsius brand grew 6%. Rockstar Energy — which Celsius acquired from PepsiCo as part of the same August 2025 deal — contributed $66.6 million but saw retail sales decline 13%, the only weak number in the release.

The portfolio-level metrics are even more striking. Celsius Holdings' US energy drink dollar share reached 20.9% in Q1 2026, up from 8.1% in Q1 2023 when the company sold a single brand. The portfolio drove 33% of total US energy category growth and 45% of zero-sugar energy growth. US retail sales hit $1.45 billion at 99.5% weighted distribution. By that retail measure, Celsius is now the #6 beverage company in the US — ahead of Primo Brands, Kraft Heinz, Nestlé, and Ocean Spray.

PepsiCo's best beverage bet is no longer a PepsiCo brand

PepsiCo's Q1 2026 results, reported April 16, showed organic revenue up 2.6% but North American beverage volume down 2.5%. Pepsi Trademark, Starry, and Gatorade all contracted. The company is mid-restage on Gatorade, has acquired Poppi for $1.95 billion (May 2025), and bought Siete Foods for $1.2 billion (January 2025) — all signals of a managed transition away from its core carbonated portfolio.

Inside that transition, the Celsius stake is the most accretive beverage line PepsiCo has. PepsiCo's initial 8.5% investment in 2022 cost $550 million. The 2.5-percentage-point top-up in August 2025 cost another $585 million. At Celsius' current market capitalisation, that 11% stake is now performing the work that PepsiCo's owned beverages can no longer do — driving energy category share, capturing zero-sugar growth, and delivering 138% revenue acceleration.

The strategic implication is uncomfortable but unavoidable. The most efficient way for a legacy beverage major to access functional and energy growth is no longer to build, restage, or even acquire — it is to take a minority position, distribute, and let the entrepreneurial brand do the work.

The international gap

The single weakness in the Q1 narrative is geographic. Monster Beverage reported Q1 2026 international revenue of $1.06 billion — 45% of its total. Celsius' international revenue is still in the low single-digit percentage of the mix. That gap is now the company's explicit strategic priority.

Celsius launched in Spain in March 2026 through Suntory Beverage & Food Spain, opened a new global headquarters in Dublin, and has expanded its Suntory partnership to include Portugal. The model is capital-light: third-party distribution agreements rather than owned infrastructure. International momentum was reported across the Nordics, UK, Ireland, France, Australia, New Zealand, and Benelux.

For European operators, the timeline is the message. Celsius is not yet a meaningful EU competitor. By H2 2026, with Suntory distribution active across multiple Western European markets, that will start to change.

What this means for the rest of the field

The Q1 2026 release reframes three competitive sets. Energy: Monster (+27% Q1, 45% international) and Celsius (+138% Q1, US-led) are now structurally different businesses, not direct comparables. Functional: Alani Nu's 100% retail growth confirms women-led functional energy is the highest-growth sub-segment in beverage and is a category Monster has not closed. Big Soda strategy: the PepsiCo/Celsius template — minority equity plus distribution — is now the case study every other major will examine. Coca-Cola's next move on its functional portfolio (BodyArmor, Topo Chico Hard, Fairlife) becomes more interesting in this light.

The next test is Q2 2026 in August. Two questions matter: can Celsius hold 20%+ category share as the comparison base resets, and does Suntory-led European expansion start to show in international revenue? If both answers come back yes, Celsius' valuation gap to Monster closes meaningfully. If not, the bear case — that Q1 was peak relative growth — gets a hearing.
