Key Details

• Transaction date: September 4, 2026; Form filed September 9, 2026 (filed late relative to the typical 2-business-day Form 4 deadline).
• Sales: 5,212 shares @ $212.21 (weighted avg.; range $211.54–$212.51 per footnote) and 413 shares @ $212.85 (weighted avg.; range $212.60–$213.04 per footnote). Total sales proceeds ≈ $1,193,921.
• Derivative actions: exercised options (code M) to acquire 5,625 shares at $7.96 each (total cost $44,756; footnote F5: option fully vested), and conversion(s) of Class B into Class A common stock reported (code C, $0 entries; see F1).
• Sales method: Shares sold pursuant to a 10b5-1 plan dated June 4, 2026 (footnote F2).
• Shares owned after transaction: not provided in the excerpt of the filing.

Context

• This was effectively a routine sale: Richardson exercised/consolidated derivative holdings and sold the resulting shares under a pre-established 10b5-1 plan. The exercise cost ($7.96/share) was minimal relative to the market sale price (~$212/share), producing substantial gross proceeds.
• Conversions reported at $0 reflect non-cash conversions of Class B to Class A common stock (see footnote F1), not additional cash purchases.
• Filing timeliness: the Form 4 was filed several days after the trade date (reported filed 9/9 for 9/4 transactions), which may be considered late under standard Form 4 timing rules.
