Rubrik, Inc. insider Kiran Kumar Choudary reported a series of open-market sales of Rubrik Class A common stock on July 15, 2026, reducing his reported position by a total of 23,400 shares. The transactions were reported on a Form 4 filed July 16 and were coded as sales, with the filing noting that they were executed under a Rule 10b5-1 trading plan adopted on April 15, 2026. The sales were completed in four price blocks. Choudary sold 15,600 shares at a weighted average price of $80.15 per share, followed by 4,800 shares at a weighted average price of $80.94, 1,200 shares at a weighted average price of $82.27, and 1,800 shares at a weighted average price of $83.37. In aggregate, the reported sales generated approximately $1.89 million in gross proceeds before expenses. The filing indicates that the weighted average prices reflect multiple trades within specified ranges rather than single executions. The 15,600-share block was sold at prices ranging from $79.61 to $80.60 per share. The 4,800-share block was sold at prices from $80.64 to $81.61. The 1,200-share block was sold from $81.70 to $82.60, and the 1,800-share block was sold from $83.00 to $83.64. Choudary undertook to provide detailed per-price share information upon request to Rubrik, its security holders, or SEC staff. Based on the reported sequence of holdings, Choudary’s Rubrik Class A common stock ownership declined from 1,012,073 shares before the reported sales to approximately 988,673 shares after the final transaction. Because the trades were made under a prearranged Rule 10b5-1 plan, the filing presents them as planned insider sales rather than discretionary trades initiated on the transaction date.
