Trimback Thomas F 4

What Happened
Thomas F. Trimback, Chief Accounting Officer of Bentley Systems (BSY), had 3,652 performance-based restricted stock units vest on 2026-01-23, resulting in the acquisition of 3,652 shares at an attributable value of $38.84 per share (total $141,844). At the same time, 1,234 shares were withheld by the issuer to cover tax withholding obligations at the same per-share value (value withheld $47,929). The primary event is an award/vesting of RSUs (acquisition); the withholding is a disposition to satisfy taxes.

Context
This was a standard vesting of performance-based restricted stock units, not an open-market purchase or sale. The tax withholding is common and represents the company retaining shares to satisfy withholding obligations (a cashless withholding), not necessarily a market sale by the insider. Such awards reflect compensation vesting rather than an explicit buy/sell signal—interpret accordingly.
