Key Details

• Transaction dates: April 21, 2026; Form 4 filed April 23, 2026 (filed within the typical 2-business-day window).
• Transaction codes: M = exercise/conversion of derivative (conversion of RSUs/PSUs to ADSs); A = grant/award.
• Prices and value: All entries show $0 (typical for vesting awards that convert to ADSs rather than open-market purchases).
• Net effect: 2,259 ADSs were reported as acquired/issued and 2,028 ADSs were reported as surrendered/converted/disposed, netting +231 ADSs issued to Engstrom.
• Shares owned after transaction: Not specified in the provided summary.
• Footnotes: Vesting relates to RSUs and PSUs granted in 2023 and 2025; each RSU/PSU converts to one Class A ADS on a one-for-one basis.

Context

• These filings reflect award vesting and derivative conversions (not an open-market purchase or sale). The disposals shown as derivative transactions are commonly used to satisfy tax withholding or settlement obligations when restricted stock/PSUs vest; the Form 4 shows those as $0 transactions. This is routine compensation-related activity and does not by itself indicate a buy or sell signal.
