Rockstar Founder Takes 4.7% Celsius Stake, Demands CEO Ouster After Earnings Miss

What happened

Celsius Holdings delivered second-quarter 2026 sales of $817.93 million, up from $739.26 million a year earlier, but the result fell short of the $870 million analyst consensus. Net income dropped to $55.29 million and earnings per share came in at 36 cents, missing the expected 43 cents, as revenue from the core Celsius brand declined 11% while newly acquired labels Alani Nu and Rockstar contributed growth. The stock fell 18% after the announcement. Days later, Russ Savage, who sold Rockstar Energy to PepsiCo in 2020 for over $4 billion, revealed he had accumulated more than 12 million Celsius shares representing about 4.7% of the company. Savage publicly called for the removal of the CEO, chief operating officer, brand manager, and marketing manager, claiming he had offered strategic advice for over a year that was largely ignored. He has volunteered to take the CEO role himself to implement cost and marketing changes he believes are necessary.

Why the stock moved

The sharp sell-off followed earnings that missed on both the top and bottom lines, signaling weaker execution than investors expected. Management attributed the shortfall to a product rationalization program and a deliberate pause in innovation during the integration of recent acquisitions, but the market interpreted those explanations as evidence of operational challenges. The subsequent activist disclosure by Russ Savage added pressure, framing the quarter as a symptom of leadership and strategy failures. While activist campaigns can sometimes lift shares by promising operational fixes, Savage's entry came after the stock had already sold off, and his criticism of management's handling of shelf space and cost structure reinforced doubts about near-term performance. Celsius also completed $100.4 million in share buybacks during the quarter, part of a $166.42 million total under its 2025 program, which some investors may view as capital allocation at odds with the need to invest in brand momentum and integration.

Bigger picture

Celsius operates in the competitive energy drink category where shelf space and brand velocity are critical. The company has built a multi-brand portfolio through acquisitions of Alani Nu and Rockstar, supported by distribution agreements with PepsiCo. However, the core Celsius label's 11% revenue decline in the quarter highlights the risk that innovation pauses and retailer rationalization can quickly erode market share in a crowded field. Savage's activist push puts a spotlight on whether the current management team can effectively integrate new brands, control costs, and stabilize the flagship label's performance. His own track record of building and selling Rockstar lends credibility to his critique, but activist interventions do not guarantee immediate operational turnarounds. The company still commands one in every five energy drink sales in the United States, indicating a strong market position, yet sustaining that share will require both execution and strategic clarity as larger players and emerging brands compete for retailer support and consumer attention.

What investors watch

Investors will monitor whether Celsius management responds to Savage's demands with concrete changes to leadership, cost structure, or marketing strategy, and whether the board engages with the activist or defends the current team. Near-term quarterly results will show if the core Celsius brand can stabilize revenue and whether Alani Nu and Rockstar continue to contribute offsetting growth. Margin trends and integration costs from the recent acquisitions will signal how effectively the company is managing its expanded portfolio. Any shifts in PepsiCo distribution arrangements or retail shelf space allocation could materially affect sales momentum. Finally, capital allocation decisions, including the pace and scale of share buybacks versus reinvestment in brand building and innovation, will reflect management's priorities and confidence in the business outlook.
