Exercise cost: 7,500 shares @ $14.69 = $110,175. Sales (gross proceeds): 5,400 shares @ $69.94 = $377,688; 1,600 shares @ $70.73 = $113,161; 500 shares @ $71.62 = $35,811. Total gross proceeds from sales ≈ $526,660. Net proceeds before taxes/fees ≈ $416,485 (sales minus exercise cost).

Key Details

Transaction date: June 18, 2026; Form 4 filed June 23, 2026 (filed after the typical 2-business-day window).
Exercise: 7,500 shares acquired via option exercise (transaction code M). Footnote F5: the optioned shares were fully vested and exercisable.
Dispositions: 7,500 shares sold in multiple open-market trades (codes S). Weighted-average prices reported; per-footnotes:

Filing notes: Trades were executed under a Rule 10b5-1 trading plan adopted March 19, 2026 (F1).
The filing also shows a 7,500-share derivative disposition at $0.00; the form does not further explain that line.

Context

This was effectively a cashless exercise: Rahul exercised options and sold all the shares the same day. Such transactions are commonly used to cover exercise costs and tax withholding; the filing shows the exercise cost and gross sale proceeds but does not itemize any withholdings.
The presence of a 10b5-1 plan indicates these sales were prearranged under an automatic trading plan rather than ad hoc market timing.
