Choudary Kiran Kumar, Chief Financial Officer of Rubrik (RBRK), has filed 90 Form 4 transactions, all in that single company. The pattern is one-sided. His total sell value is $24,878,699.78, with zero open-market purchases and zero acquisitions. Every recent trade is a sale, an option exercise, or a tax withholding, with no buys in the latest batch.
The most recent cluster came on September 17, 2026, with four open-market sales totaling $623,150.36. That followed a heavier day on September 15, when Kumar sold shares in six separate transactions worth $404,185.78, exercised options with no cash value, and had $1,402,299 in shares withheld to cover taxes. Earlier in the same month, on August 24, he sold $983,188 across three trades after another zero-value option exercise. July 15 showed the same rhythm: six sales totaling $1,038,034, paired with an option exercise.
The sales are routine for an executive holding equity compensation. The option exercises (code M) and conversions (code C) carry no dollar value, meaning they are mechanical. The tax withholdings (code F) are automatic. What remains is a steady stream of open-market sales, spread across multiple dates, with individual values ranging from roughly $20,000 to $522,845. There is no purchase activity anywhere in the record, and the recent direction is uniformly toward reducing his position.
