Kiran Kumar Choudary, Chief Financial Officer of Rubrik, Inc., executed 8 separate sales totaling 28,000 shares for $2,288,374.00 on 2026-07-15 via a pre-arranged 10b5-1 trading plan adopted 2026-04-15 — making this a scheduled, non-discretionary transaction rather than a discretionary trade. The CFO retained 984,073 shares post-transaction, representing a -2.8% reduction from prior holdings. His prior trades at this ticker show 90-day post-sale returns of +15.8%, +19.4%, +21.4%, +17.0%, and +5.9%, indicating his recent sales have been followed by stock appreciation. Rubrik's fundamentals remain mixed: Q1 revenue reached $387,068,000.00 with annual growth of +48.5%, but the company posted a net loss of $-41,853,000.00 in the quarter and remains unprofitable on a full-year basis.

CTO Arvind Nithrakashyap sells 38,460 shares of RBRK for $3,332,421.48 via scheduled 10b5-1 plan (July 6-8)

Arvind Nithrakashyap, Chief Technology Officer of Rubrik, Inc., executed 16 separate sales totaling 38,460 shares for $3,332,421.48 across July 6-8, 2026, reducing his non-derivative holdings from 342,071 to 303,611 shares (-11.2%). This transaction was conducted under a pre-arranged 10b5-1 trading plan adopted on 2025-10-15, meaning it was scheduled rather than discretionary. The sales occurred at prices ranging from $83.37 to $89.28 (blended average $86.65), while the current stock price stands at $84.40, and the stock has risen +17.7% over the past 30 days and +82.8% over 90 days. Notably, the insider maintains substantial derivative holdings across three ownership vehicles totaling derivative securities that reflect an ongoing stake in the company beyond the common shares sold.

Director Thompson sold 13,500 shares of RBRK for $1.1M via 10b5-1 plan on 2026-07-01, reducing non-derivative holdings by 61.8%.

John Wendell Thompson, Director, executed 6 separate sales totaling 13,500 shares for $1,116,038.00 under a pre-arranged 10b5-1 trading plan adopted on 2025-10-06, reducing his non-derivative holdings from 21,862 shares to 8,362 shares at a blended average price of $82.67. This scheduled transaction occurs as the stock trades at $82.01, down 17.8% from its 52-week high of $99.75, though up 59.4% over the 90-day window. Rubrik remains unprofitable with net income of $-63,829,000.00 on revenue of $350,166,000.00 in the latest quarter, though the company posted 48.5% annual revenue growth. Because this sale is part of a pre-arranged 10b5-1 plan, it reflects automatic execution rather than discretionary timing; Thompson retains 199,948 shares in derivative holdings across stock options and Class B common stock, maintaining a meaningful stake in the company.

Thompson (RBRK Director) sells 13,500 shares for $1,141,288.63 via scheduled 10b5-1 plan adopted 2025-10-06

John Wendell Thompson executed 11 separate sales totaling 13,500 shares for $1,141,288.63 on 2026-06-01 at prices ranging from $79.77 to $86.07, reducing his non-derivative holdings by 61.8% from 21.9K to 8.4K shares. This transaction is part of a pre-arranged 10b5-1 trading plan adopted on 2025-10-06, making it scheduled rather than discretionary. Thompson retains significant derivative holdings totaling 210,948 shares across stock options and Class B common stock, so his overall economic position remains substantial. The sale occurs against a backdrop where RBRK traded at a current price of $79.46, down 22.8% from its 52-week high of $103.00, while the company generated $350.2M in quarterly revenue but posted a net loss of $-63.8M most recently and remained unprofitable over its full fiscal year.

CTO Arvind Nithrakashyap sold 225,087 shares for $18.9M across 3 days via pre-arranged 10b5-1 plan

Arvind Nithrakashyap, Chief Technology Officer, executed 17 separate sales totaling 225,087 shares (225.1K shares) for $18,873,676.52 ($18.9M) on 2026-06-01 through 2026-06-03 under a pre-arranged 10b5-1 trading plan adopted on 2025-10-15. This represents a 41.7% reduction in his non-derivative holdings, bringing them from 539,135 shares to 314,048 shares, though substantial derivative holdings of 30,438,396 Class B shares remain across three ownership vehicles. The transaction is scheduled rather than discretionary; the blended average price of $83.85 compares to the current price of $79.46, reflecting the stock's recent surge of +37.2% over 30 days and +42.2% over 90 days. At the RBRK ticker level, his five prior sales have shown mixed forward timing outcomes, ranging from -31.7% to +70.8% over 90 days post-trade. Notably, the company reported a net loss of $63.8M in its latest quarter despite +48.5% annual revenue growth, indicating continued unprofitability despite topline expansion.

CFO Choudary Kiran Kumar sold 20,000 shares at $51.69 avg; stock down 9.7% in 30d, 48.2% from 52-week high.

Rubrik's CFO executed 4 separate sales on 2026-04-07 totaling 20,000 shares for $1,033,733.00, reducing holdings by 3.5% to 549.9K shares post-transaction. The timing context is notable: the stock has declined 9.7% over the past 30 days and 28.0% over 90 days, currently trading 48.2% below its 52-week high of $99.74. At the same ticker, the CFO's prior 5 trades were all sells (2026-01-16 through 2026-03-24), with 30-day returns ranging from -20.3% to -6.2% on the measurable ones—a pattern suggesting consistent selling during a period of sustained downward price movement. However, this filing involves a derivative conversion (Table II), so the reported 549.9K shares post-transaction does not represent the insider's total position; deep analysis of the derivative holdings table when populated will be necessary to assess the full economic exposure. The company remains unprofitable (net income of $-63.8M in the most recent period) despite strong revenue growth of 48.5% annually.

Director Mark D McLaughlin bought 10,638 shares of RBRK at $47.21 for $502.2K, tripling holdings to 13.6K shares amid stock down 51.3% from 52-week high.

Director Mark D McLaughlin purchased 10,638 shares at $47.21, a discretionary open-market buy that increased his holdings by 354.5% to 13,639 shares post-transaction. The purchase occurred at a price 51.3% below the 52-week high of $99.74, following a 36.5% decline over the prior 90 days. However, his cross-ticker track record shows 2 prior buys with an average 90-day return of -11.8% and a 0.00% win rate, suggesting his prior buy-on-weakness trades have not preceded recoveries. The company is unprofitable with net income of $-63,829,000.00 despite 48.5% annual revenue growth, creating a tension between growth and near-term profitability that adds complexity to interpreting the purchase motive.

CTO Nithrakashyap Arvind sold 28,967 shares of RBRK at $48.20 on 2026-03-24; stock down 52.3% from 52-week high and unprofitable on $350.2M revenue.

Nithrakashyap Arvind, Chief Technology Officer, sold 28,967 shares at $48.20, reducing his holdings from 377,635 shares to 348,668 shares (a -7.7% reduction). The timing is notable: RBRK has declined 39.5% over the past 90 days and is currently 52.3% below its 52-week high of $99.74, while the insider's prior four sales at this ticker were well-timed at the 90-day mark, suggesting a pattern of selling before declines. However, the company's fundamentals show persistent unprofitability with a net loss of $-63,829,000 on annual revenue growth of +48.5%, indicating the stock weakness reflects underlying operational challenges rather than temporary softness. The sale represents a discrete reduction in a concentrated position by a key technical executive during a period of significant drawdown, warranting monitoring of whether this reflects internal confidence levels or positions the insider ahead of further pressure.

CFO Choudary sold 122.6K shares of RBRK at $48.20; stock down -52.3% from 52-week high and -39.5% in 90 days.

Choudary Kiran Kumar, the CFO, sold 122,613 shares on 2026-03-24 at $48.20, reducing his holdings by 17.8% from 687,514 to 564,901 shares. The sale occurs amid sharp downward momentum: RBRK is down 39.5% over the prior 90 days and -52.3% from its 52-week high of $99.74. His prior five trades at RBRK, all conducted in January and February 2026, have also all declined in the 30-day window (ranging from -6.2% to -21.0%), while the company operates unprofitably (net income of $-63.8M despite 48.5% annual revenue growth). This filing involves a derivative conversion transaction; the full scope of his remaining stake may exceed the 564.9K shares shown in Table I.

CFO Choudary Kiran Kumar sells 20,000 shares (20.0K) for $1.1M under pre-arranged 10b5-1 plan at Rubrik (RBRK)

The sales occurred at prices ranging from $52.55 to $54.39 per share with a blended average of $54.17. Because this transaction is part of a pre-arranged scheduled trading plan rather than a discretionary decision, it reflects commitment to an earlier-established program rather than a timing judgment at current market conditions. The CFO retains 475.0K shares post-transaction, representing a 4.0% reduction of prior holdings.
