Ernest Scott Santi’s SEC Form 4 filings reveal a pronounced sell-side bias concentrated almost entirely in Illinois Tool Works (ITW), with a secondary, passive accumulation pattern in W.W. Grainger (GWW). Over 54 reported transactions across the two industrial names, Santi has executed zero open-market purchases and roughly $136.5 million in total sales, all of which occurred in ITW. The most recent selling cluster came on February 4, 2026, when he disposed of ITW shares across six separate transactions totaling approximately $48.7 million, following an option exercise valued at $24.1 million the same day. A similar pattern emerged on February 20, 2025, with three sales worth roughly $19.4 million paired with an $12.0 million option exercise, and again on February 4, 2025, with a single $1.15 million sale.
The recurring February sales suggest a systematic, calendar-driven liquidation of vested equity rather than opportunistic market timing, with the option exercises (code M) mechanically feeding the corresponding open-market sales (code S). Outside these concentrated dispositions, Santi’s activity is dominated by compensation-related grants (code A) and tax withholding (code F). He received recurring ITW awards—most recently $479,713 on May 8, 2026, and $34,999 on February 6, 2026—alongside smaller quarterly GWW grants ranging from roughly $21,000 to $26,000. A single $1.27 million tax-withholding event on ITW shares in February 2026 further underscores the automatic nature of much of his non-sale activity.
The overall footprint is unambiguous: Santi is a net seller of ITW stock, with his only discretionary transactions being large, periodic sales that align with option vesting schedules. His GWW holdings, by contrast, show no sales at all—only recurring grants and a zero-value award in April 2026—indicating a passive accumulation stance in that name. With no purchases in either company, the data paints a picture of an executive monetizing ITW equity compensation while letting GWW awards build without interference.
