Rubrik (RBRK) Chief Revenue Officer Brian K. McCarthy filed a Form 4 disclosing the sale of 12,500 Class A shares on 01-Aug-2025 under a pre-arranged Rule 10b5-1 trading plan adopted 27-Jun-2024. Transaction prices ranged from $83.97–$89.88, with weighted-average prices reported in six separate blocks ($84.65, $85.56, $86.74, $87.68, $88.84, $89.88).
Post-sale, McCarthy still beneficially owns 418,552 shares, implying he disposed of roughly 3% of his prior 431,052-share position. No derivative transactions were reported. Because the sales were planned and represent a small fraction of his holdings, the filing is generally viewed as routine and is unlikely to signal a change in the company’s fundamental outlook.

The filing shows routine, pre-planned diversification rather than a major change in ownership. No new awards were granted, and there is no indication of unusual insider activity beyond the small net reduction in shares.
