Insights

Form 4 shows equity awards cashed out at $24 in a going-private merger.

The filing indicates that OneStream, Inc. completed a merger in which all reported Class A Common Stock and stock options held by Chief Accounting Officer Pamela McIntyre were canceled and converted into cash-based rights. Transaction code D reflects dispositions to the issuer, not open-market sales.

Footnotes specify that each common share became entitled to $24.00 in cash, while vested options receive cash equal to shares times the excess of $24.00 over their exercise price. Unvested options and RSUs convert into contingent cash awards with existing vesting terms. Overall, this is a structural change tied to the merger rather than a discretionary trade, so the signal is neutral for insider sentiment.

Agreement and Plan of Merger financial
"Pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated January 6, 2026..."
An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.

restricted stock units ("RSUs") financial
"Represents an equal number of restricted stock units ("RSUs"). At the Effective Time, each unvested RSU award was cancelled..."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
