Insights

Executive equity is cashed out in an all-cash merger, not sold on the market.

The transactions show Scott Leshinski, president of OneStream, Inc., disposing of stock options and Class A shares back to the issuer as part of a cash merger. Code D and the description “disposition to issuer” indicate no open‑market buying or selling.

The footnotes explain an Agreement and Plan of Merger where each common share becomes a right to receive $24.00 in cash, and both vested and unvested options and RSUs convert into cash based on that price. This represents a change in ownership structure rather than a discretionary trade.

Because all visible derivative positions and shares in this filing go to zero after the merger’s Effective Time, the Form 4 mainly clarifies how the executive’s equity was treated in the acquisition, rather than signaling a view on future performance.

Agreement and Plan of Merger regulatory
"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.

FAQ

What did OneStream (OS) president Scott Leshinski report on this Form 4?

He reported issuer-related disposals of stock options and Class A common shares. These positions were cancelled and converted into cash rights under a merger agreement, leaving no remaining holdings from the reported awards after the Effective Time of the transaction.

Was there an open-market sale of OneStream (OS) shares in this filing?

No. The filing uses transaction code D, described as a “disposition to issuer.” The equity was cancelled and exchanged for cash in connection with a merger, rather than sold on the open market to third-party investors through regular trading on an exchange.

What cash consideration did OneStream (OS) shareholders receive in the merger?

Each share of OneStream Class A Common Stock was cancelled and converted into the right to receive $24.00 per share in cash, less applicable withholding taxes. This per-share cash price also underpins the cash treatment of options and restricted stock units described in the footnotes.

How were OneStream (OS) stock options held by the president treated in the merger?

At the Effective Time, each vested option was cancelled for cash equal to shares times the excess of $24.00 over the exercise price. Each unvested option became a contingent cash award using the same formula, with original vesting terms continuing after the merger transaction.

What happened to OneStream (OS) restricted stock units in this transaction?

Each unvested RSU award was cancelled and replaced with a contingent cash right. The cash amount equals the product of the $24.00 per-share price and the RSU share count, less taxes, while the original vesting conditions continue to govern when that cash can ultimately be received.

What corporate transaction drove these Form 4 disposals at OneStream (OS)?

The disposals stem from an Agreement and Plan of Merger involving OneStream, its subsidiary, and entities referred to as Parent and merger subsidiaries. Through the First and Second Mergers, OneStream became a subsidiary of Parent, triggering the cash conversion of shares, options, and RSUs.
