OneStream (OS) Director Michael Burkland Sells Shares in Merger

What Happened
Michael Burkland, a OneStream director, had multiple holdings (stock, RSUs, units and options) cancelled and converted to cash as part of the merger closing on April 1, 2026. The Form 4 reports dispositions of 7,130 shares and three derivative-based dispositions totaling 705,314 units/awards (50,000; 169,257; 486,057) — 712,444 total securities. Under the merger terms, RSUs and common units were cashed out at a Per Share Price of $24.00, implying approximately $17.1 million in cash for those items; option treatment was cash based on the excess of the $24 price over the option exercise price, so proceeds for options may differ.

Context
These were not open-market sales but merger-related cash settlements: outstanding director RSUs and certain units were accelerated and paid out at the merger price, and options were cashed out per the agreement. Such filings reflect corporate transaction logistics rather than a director trading on the open market, and do not by themselves indicate the director’s market view.
