Prince Matthew 4

What Happened
Matthew Prince (reported as a 10% owner) converted Class B shares into Class A common stock and sold a large block of the resulting shares from March 16–18, 2026. Across those three days he sold 143,534 shares in open-market transactions for total proceeds of approximately $30,555,700 (prices reported as weighted averages for multiple trades). The filing shows conversions of 29,473, 52,384 and 52,384 shares (Class B → Class A) and then the sales; the activity was reported as sales (not purchases).

Key Details

• Transaction dates: March 16–18, 2026. Filing date: March 18, 2026.
• Sales: 143,534 shares sold for ~$30.56M total. Reported trade prices (weighted averages) roughly ranged from about $207.5 to $226 (see footnotes for detailed ranges and per-trade breakdowns).
• Conversions: 134,241 shares were converted from Class B to Class A (one-for-one conversion per filing). Some derivative-conversion lines report $0 consideration consistent with a conversion, not a cash sale.
• Net change: after conversions and sales the transaction set shows a net reduction of 9,293 shares (134,241 converted in vs. 143,534 sold out). The filing does not state a single consolidated "shares owned after" number in the materials provided here.
• Notable footnotes: sales were effected pursuant to a Rule 10b5-1 trading plan (footnote F3). Several holdings are shown as held in trusts for which Prince serves as trustee or investment advisor (multiple trust footnotes). Prices reported are weighted averages across multiple trades (many footnotes F4–F31).
• Timeliness: filing covers trades dated Mar 16–18 and was filed Mar 18, 2026; the form’s remarks note this is the first of two Form 4s reporting these transactions.

Context

• These transactions are conversions of convertible Class B shares and subsequent open-market sales. Conversions are non‑cash movements that convert voting Class B shares into tradable Class A shares; many insiders then sell shares under planned programs.
• The sales were executed under a pre-established 10b5-1 plan, which typically indicates pre‑arranged, rule‑compliant selling rather than opportunistic trading. As a 10% owner (and long‑time founder/CEO in public filings), Prince’s trades are significant in size but follow a pre-set plan.
• Retail investors should view large, planned sales under 10b5-1 as routine liquidity management; they are factual disclosures of selling activity and do not, by themselves, prove a change in company outlook.
