Wiechmann Andrew C. 4

What Happened
Andrew C. Wiechmann, Chief Financial Officer of MSCI Inc. (MSCI), received a grant of 1,825 restricted stock units (RSUs) on January 30, 2026. The RSUs were awarded at a $0 acquisition price (typical for equity compensation) and are expected to vest and convert to shares on the third anniversary of the grant date. Per the filing footnote, the final number of shares issued at vesting will range from 100% to 130% of the target RSUs depending on achievement of a 2026 fiscal-year performance metric.

Context
RSU grants are a form of compensation and retention incentive; they are not an immediate cash purchase or sale and do not imply immediate market activity. Because these units vest in the future and are performance-adjusted, they represent potential future equity rather than an immediate change in insider holdings available for sale.
