His total sell value is $23,851,363.64, and his total buy value is zero. He has not made an open-market purchase in the recent period, and his recent activity shows 15 sales with no buys.
The recent trades cluster on specific dates, and each date pairs option exercises (code M) and conversions (code C) with open-market sales (code S). On August 24, 2026, Kumar sold shares worth $29,979, $522,845, and $430,364. On July 15, 2026, he sold in eight separate transactions, ranging from $34,060 to $1,250,340, with a combined value of roughly $2.2 million. On April 7, 2026, he sold $47,799, $273,260, $515,100, and $197,574. The sales follow option exercises, which are mechanical, and the sales themselves are the discretionary part of the transaction.
The only non-sale event in the recent window is a June 16, 2026, tax withholding (code F) of $976,711.05, which is automatic, and an April 14, 2026, grant (code A) with no cash value. Kumar has not acquired shares through open-market purchases at any point in the filing history. The direction is consistent: he sells after exercising options, and the dollar values are substantial, with the largest single sale at $1.25 million.
