Key Details

• Transaction date: February 18, 2026 (Form 4 filed 2026-02-19; timely).
• Primary reported acquisition: 21,600 shares acquired via exercise at $11.17/share = $241,272.
• Additional report lines at $0.00 reflect conversion of Class B common stock into Class A common stock (per footnotes), not a market sale.
• Ownership after transaction (per filing footnote): 28,431 shares held across trusts (1,246 + 1,246 + 25,939), which includes 882 shares contributed to the WB Trust on 1/27/2026.
• Vesting/status: Shares/rights reported as fully vested (Footnote 5).

Context

• This filing reports an acquisition (exercise/conversion) rather than an open-market purchase or sale. The exercise at $11.17/share required cash consideration ($241,272). Entries showing disposals at $0.00 are tied to the conversion of Class B to Class A and reflect corporate conversion mechanics, not a cash sale to a third party.
• No 10b5-1 plan, tax-withholding sale, or late filing was indicated in the filing.
