Key Details

• Grant: 2,864 restricted shares on 2026-09-15 @ $275.09 (F2 — restricted stock under CME Omnibus Stock Plan; vests in four equal annual installments, subject to continued service). Total value ≈ $787,858.

Context

• The primary event is an equity award (restricted stock grant). Such awards are compensation, not an open-market purchase; they become valuable as they vest.
• The disposals were share surrenders to satisfy tax withholding, a routine administrative step (not an open-market sale that signals a view on the stock).
• Footnotes clarify the grant’s vesting schedule (F2) and that surrendered shares were used for tax withholding (F3). The May trust transfer (F1) changes how ownership is held but is exempt from Section 16 reporting rules.
