Rattray Sandy C. 4

What Happened

• Sandy C. Rattray, a director of MSCI Inc., was issued 388 shares as an award (code A) on May 1, 2026. Simultaneously, 32 shares were disposed (code F) when MSCI reacquired them to satisfy tax withholding obligations. The filing reports $0.00 per-share price for both entries (typical for RSU vesting conversions).

Key Details

• Transaction dates: May 1, 2026 (reported in Form 4 filed May 5, 2026).
• Actions: 388 shares acquired (award/grant, A); 32 shares reacquired/withheld for taxes (F).
• Reported prices: $0.00 per share (reflects conversion/award mechanics, not an open-market trade).
• Net shares credited from this event: 388 issued less 32 withheld = 356 net shares (based on reported counts).
• Footnotes: F1 notes MSCI reacquired shares to satisfy withholding for the vesting/conversion of 385 RSUs originally granted May 1, 2025; F2 indicates some restricted stock units vest on May 1, 2027.
• Shares owned after transaction: not disclosed in the filing.
• Timeliness: Form 4 was filed May 5, 2026 — within the standard two-business-day reporting window for a May 1 transaction (not marked late).

Context

• This was an RSU vesting/award event, not an open-market purchase or sale by the insider. The F-code transaction is a routine company withholding of shares to cover tax obligations (a cashless withholding), not a sale to a third party. Such award vestings are common and typically reflect scheduled compensation rather than a signal of buy/sell intent.
