Rubrik (RBRK) CFO Kiran Kumar Sells Shares

What Happened

• Kiran Kumar, Chief Financial Officer of Rubrik, reported the sale of 10,000 shares in open‑market transactions on August 24, 2026, generating total proceeds of approximately $983,188 (3 tranches: 4,400; 5,300; 300 shares).
• The sales were executed at weighted‑average prices of $97.81, $98.65 and $99.93, respectively. The Form 4 also shows conversions/exercises of derivative securities reported at $0.00 per share (i.e., option exercise/conversion events rather than cash purchases).
• These sales are generally a selling event (not a purchase) and were carried out under a prearranged trading plan (see footnote).

Context

• The filing shows exercise/conversion of derivative securities at $0.00 per share, which typically indicates option exercise or conversion events rather than a cash purchase. Some or all of the exercised/converted shares were then sold in the open market (a common cashless or near‑cashless outcome).
• The sales were completed under a 10b5‑1 plan (prearranged trading plan), which is a routine method executives use to sell shares without active timing decisions. This is factual reporting, not an indication of management’s future expectations.
