Rhea-AI Filing Summary
Rubrik, Inc. director John Wendell Thompson reported a mix of share sales, option exercises, and equity grants in Rubrik stock. On June 1, 2026, he and a related trust sold a combined 13,500 shares of Class A Common Stock in open-market transactions at weighted-average prices generally in the low-to-mid $80s per share, under a pre-arranged Rule 10b5-1 trading plan adopted on October 6, 2025.

Separately, on June 3, 2026, Thompson received a grant of 3,709 restricted stock units, which will vest in four equal quarterly installments from September 15, 2026 through June 15, 2027, subject to continued service.

Insights
Planned sales, option exercises, and new RSUs look like routine portfolio and compensation activity.
Director John Wendell Thompson reported open-market sales of 13,500 Rubrik Class A shares, alongside exercises and conversions covering 33,000 shares. A footnote states the sales were executed under a Rule 10b5-1 trading plan adopted on October 6, 2025, indicating they were pre-scheduled rather than opportunistic.
He also exercised stock options at an exercise price of $4.38 and converted Class B Common Stock, while a derivative position tied to 815,338 underlying Class A shares remains indirectly held. This suggests the transactions represent partial monetization rather than an exit. The grant of 3,709 RSUs, vesting quarterly from September 15, 2026 to June 15, 2027, is standard director compensation structure.
The combination of continued large indirect holdings and ongoing equity awards points to routine governance and compensation practices. The net-sell of 13,500 shares appears modest relative to the remaining position, so the overall signal from this Form 4 is neutral for long-term investors.

Rule 10b5-1 trading plan financial
"This sale reported on this Form 4 was effected pursuant to a Rule 10b5-1 trading plan, adopted October 6, 2025."
A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.
restricted stock units ("RSUs") financial
"Represents the grant of restricted stock units ("RSUs") that will vest over a one-year period, in four (4) successive equal quarterly installments..."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
weighted average price financial
"The reported price in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging..."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
Class B Common Stock financial
"Each share of Class B Common Stock held by the Reporting Person will automatically convert into one share of Class A Common Stock..."
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
co-trustee financial
"The shares are held of record by John and Sandra Thompson Trust, for which the Reporting Person serves as a co-trustee and shares voting and dispositive power..."
