Celsius proves “better-for-you” can still steal energy-drink growth—yet its base brand is shrinking, and margins are taking the hit

In Q2, Celsius effectively “bought” growth with portfolio mix. Total revenue rose to $817.9M (+11% YoY), but the base CELSIUS brand revenue fell to $387.0M (-11.7% YoY) while acquisitions/roll-ups carried the quarter.

That matters because “better-for-you” energy-drink theses fail when consumers trade down within the same value proposition (same-customer, less repeat). Q2 shows some of that internal pressure—yet it also shows the portfolio can still win shelf space and category dollars.

Celsius’s Q2 release ties its retail momentum to two things investors can measure: (1) how much shelf dollars its portfolio captures inside the U.S. RTD energy category and (2) how much incremental growth its portfolio generates when category growth is occurring.

For Q2, Celsius disclosed that its portfolio (CELSIUS, Alani Nu, and Rockstar Energy) tracked retail sales increased 31.0% over the 13-week period ended Jun 28, 2026, while the portfolio held ~20.1% dollar share in the U.S. RTD energy category. It also disclosed the portfolio contributed ~30% of the $640 million growth in zero-sugar U.S. energy during Q2 2026.

That is the investor “yes” part of the thesis: the better-for-you/zero-sugar channel can still take dollars even when the category’s overall buying pattern softens.

Q2’s margin and brand weakness are consistent with a common “energy in a slowing shopper tape” pattern: companies buy repeat by spending more trade/promo, but that can temporarily weaken gross margin.

In the Q2 release, Celsius attributed the gross margin decline primarily to higher promotional and incentive activity as a percentage of revenue and channel mix; it also noted offsets from integration improvements and the absence of an inventory step-up expense related to the Alani Nu acquisition.

Separately, the release includes retailer-level constraints that can cap velocity. Celsius disclosed that productivity improved with ~7% fewer distribution points and that dollars per point rose ~16% vs. 1Q, but it flagged that gaining cold vault/permanent cooler space can require more retailer capital and labor—meaning growth can stall until retailers are willing/able to invest in the cooler footprint.

Energy drinks look “simple” at retail, but the margin bridge is where the category is won. Celsius’s Q2 disclosure says gross margin fell to 48.1% from 51.5%, with commentary including (a) promotional/incentive intensity and channel mix, (b) integration improvements, and (c) commodity cost inflation—specifically aluminum—partially offsetting integration gains.

This is important for the better-for-you niche because it’s often priced as a premium. If premium pricing holds, margins can be resilient. If premium relies on continued promo intensity and the cost stack rises (aluminum), margins compress even when share is stable.

Monster and Red Bull dominate the mainstream U.S. energy market with long-established distribution and brand scale. The better-for-you wedge typically works when it is both (1) a flavor/format innovation engine and (2) a repeat-friendly, habit-building “morning-to-workout” choice.

Celsius’s Q2 pattern answers part of that: portfolio share and zero-sugar growth contribution remain strong. But the core brand’s retail sales down ~2% and -11.7% revenue decline show the habit engine inside the flagship line is currently weaker than the portfolio story.

For PepsiCo, the market relevance is that it controls major beverage routes and can influence shelf conditions through broader category execution. The topic claim that PepsiCo’s U.S. energy volumes “still haven’t recovered” is not quantified in the Celsius Q2 source material, so this article does not treat that as a verified figure.

Short term (days to the next couple quarters), the key monitoring items are: gross margin stabilization and whether promotional/incentive intensity stays elevated. Q2 already flags that promotional/incentive and channel mix are involved in the margin decline.

Long term (1–3 years), the thesis depends on physical availability and repeat. Celsius’s Q2 disclosure about cold vault/permanent cooler space suggests that the merchandising “infrastructure” must expand for sustained velocity. If retailer capital/labor constraints lift and Celsius can convert cooler placement into repeat, the core brand’s decline can stabilize and flip.

Right now, the most investable interpretation is mixed: portfolio momentum looks healthy, but the core brand needs to stop bleeding and margins need to stop deteriorating.
