A fresh Form 4 filing shows Damon DeSantis, a director at Celsius Holdings, Inc. (CELH), purchased 16,000 shares of the sports and energy drink maker on the open market on September 15, 2026. The shares were bought at $27.95 apiece, for a total outlay of $447,200. Following the purchase, DeSantis directly holds 2,728,187 shares of the company.
This was not an isolated move. The filing is part of a broader cluster of insider buying activity at Celsius Holdings over a 48-hour window. Between September 14 and September 15, 2026, SEC disclosures show two separate open-market purchases at the company, together totaling $1,000,200. Multiple insiders putting personal capital into the stock within such a tight timeframe is the kind of pattern that tends to draw attention from filing trackers, and it is why whoisbuyingnow.com has flagged this activity under our ‘cluster buy’ classification.
Why Clustered Buying Gets Attention
A single insider purchase can reflect any number of personal factors and does not, on its own, say much about a company’s prospects. But when several insiders buy on the open market within a short window, it becomes a more distinct signal. Academic research on insider trading disclosures has found that clustered buying activity — multiple insiders purchasing shares around the same time — has historically been associated with periods of stronger relative stock performance compared with isolated single-insider transactions. That research describes a statistical pattern observed across many companies over time, not a prediction about any specific stock, and it should not be read as guidance for what happens next at Celsius Holdings.
What the Filing Shows
The DeSantis transaction itself was a straightforward open-market buy, meaning the director used personal funds to acquire the shares at prevailing market prices rather than receiving them through options, grants, or other compensation-related mechanisms. That distinction matters to filing watchers because open-market purchases are generally viewed as a clearer expression of an insider putting their own money on the line, compared with transactions tied to equity compensation vesting schedules.
Celsius Holdings has drawn periodic attention from insider-trading trackers given its position in the competitive energy drink category. This latest cluster of purchases, spanning two transactions and just over $1 million in combined value, adds a new data point to the company’s insider trading history. As always with these disclosures, the filing reflects a snapshot of activity as reported to the SEC, and readers can review the underlying documents for full transaction details.
