What Happened
Mark W. Begor, CEO and a director of Equifax Inc. (EFX), exercised 37,791 option-derived shares on July 24, 2026 at $112.46 per share (total exercise cost ~$4,249,976) and sold the same 37,791 shares in multiple open-market blocks that day for aggregate proceeds of ~$6,506,255 (weighted-average sale price ≈ $172.16). The transactions indicate an exercise followed by immediate sales (i.e., a cashless or simultaneous disposition).

• Sales: 37,791 shares sold across multiple blocks (coded S = open-market sale) for total proceeds ~$6,506,255. Per-block weighted average price ranges are provided in the filing (see footnotes); overall weighted-average ≈ $172.16/sh.

• Notable footnotes: sales were effected under a Rule 10b5-1 plan adopted 10/28/2025 (F1); multiple footnotes list the per-block price ranges (F3–F10); option vesting referenced (vested in three equal annual increments beginning 5/4/2019, F11); F2 describes components included in reported ownership (dividend equivalents and 226 ESPP shares).

Context

• This was an exercise of previously granted options followed by sales of the exercised shares—commonly a cashless exercise/sale pattern. The sales were executed under a pre-established 10b5-1 plan, which typically sets trade details in advance to avoid concerns about trading on material nonpublic information.
• For retail investors, purchases by insiders tend to be more directly informative about conviction; sales (especially those following option exercises or governed by 10b5-1 plans) can be routine (taxes, diversification) and do not necessarily indicate a change in sentiment.
• Transaction codes: M = option exercise/conversion; S = open-market sale.
