McIntyre Pamela 4

What Happened
Pamela McIntyre, Chief Accounting Officer of OneStream, disposed of a total of 3,047 shares in mid-March 2026. On March 10, 2026, 1,032 shares were withheld by the company to satisfy tax withholding related to the net settlement of restricted stock units (RSUs) (value $24,458 at $23.70/share). On March 11, 2026, she sold 2,015 shares in an open-market sale at $23.68/share for proceeds of $47,715. The withheld shares are not a sale by the reporting person; the open-market sale was executed under a pre-arranged 10b5-1 trading plan.

Context
Tax withholding of RSUs (cashless/net settlement) is a common administrative step and does not signal an active decision to sell by the insider. The open-market sale was executed under a 10b5-1 plan, which is a pre-established trading arrangement that allows insiders to trade on a set schedule and is generally considered routine. Sales by executives are common and do not by themselves indicate a change in company outlook.
