Why are Celsius shares rising sharply today?

Celsius shares rose 11.1% during mid-day trading, rebounding strongly from their 52-week lows, after Russ Savage, founder of Rockstar Energy, told CNBC that he has built a stake of around 12 million shares—representing about 4.7% of the company—calling for the removal of the current CEO, John Fieldly, and suggesting himself as a candidate to lead the company. Savage also said that Celsius suffers from multiple layers of management and a lack of sufficient accountability, warning that the company risks losing vital shelf space to competitors if leadership mistakes are not corrected quickly.

The activist disclosure came just one day after the shares collapsed following a far-from-expected Q2 2026 earnings report. Celsius posted adjusted earnings per share of $0.36 versus analysts’ expectations of $0.43, while revenue came in at $817.90 million, significantly below the estimated $886 million—despite representing an 11% year-over-year increase. Revenue for the company’s main Celsius brand fell by roughly 11.7% year-over-year, attributed to an inventory rebalancing and streamlining of inventory holding units (#SpaceXMarketCapTops$1.613TPassingMeta #USSolarStocksRisePremarket #SKHynixToInvest19.1TWonInM17Plant #BrentClimbs3.8%To$82.49 #$TRUMP
