Bosworth Andrew 4

What Happened

• Andrew Bosworth, Chief Technology Officer at Meta Platforms (META), had 16,388 RSUs convert to Class A shares on May 15, 2026. To cover tax withholding, 8,127 shares were withheld (valued at $618.43 each, ~$5.03M). On May 18, he sold 7,847 shares in open-market transactions under a Rule 10b5-1 plan, generating about $4.77M. Combined value shown on the filing is roughly $9.8M.
• These transactions reflect RSU settlement and subsequent sales (routine monetization), not an outside-market purchase.

Key Details

• Transaction dates: RSU conversion/settlement on 2026-05-15; open-market sales on 2026-05-18. Filing date: 2026-05-19 (timely).
• Prices/proceeds: Tax-withheld shares valued at $618.43 (8,127 shares → $5,025,981); market sales of 7,847 shares at weighted-average prices ≈ $604.51–$611.83 per share → ~$4,769,641. Some sale line items report weighted-average price ranges in footnotes.
• Net shares from this vesting: 16,388 vested − 8,127 withheld − 7,847 sold = 414 shares remaining from this vesting event (the filing does not state total beneficial ownership after the transactions).
• Notable footnotes: F2 = shares withheld to satisfy tax withholding (not a market sale); F3 = open-market sales effected under a Rule 10b5-1 trading plan; other footnotes provide RSU vesting schedule and weighted-average price ranges for grouped sales.
• Transaction codes: M = exercise/conversion of derivative (RSU settlement), F = tax withholding/net settlement, S = open-market sale.

Context

• This was a net settlement of RSUs (conversion to shares with issuer withholding to meet tax obligations) followed by planned sales under a pre-established 10b5-1 plan — a common, routine way insiders monetize vested equity. Such transactions are administrative and don’t necessarily signal a change in the insider’s view of the company.
