Insights

Securities Analyst

TL;DR: Director Michael Corbo's equity converted to cash at $23.00 per share due to a merger that took the company private.

The Form 4 documents a corporate change where Ferrero International S.A. completed a merger causing WK Kellogg Co common shares to be cancelled and converted into a cash payment of $23.00 per share at the Effective Time. The reporting person disposed of 24,354 common shares and had deferred and phantom equity (6,510.37 DSUs and 1,239.99 phantom units) converted into cash rights tied to the same per-share price. The filing is routine for Section 16 reporting following a corporate acquisition and provides clear, quantifiable settlement terms for equity holders.

Corporate Governance Expert

TL;DR: The merger resulted in cancellation of public shares and cash-out of equity awards, removing open-market holdings for the reporting director.

This Form 4 confirms that at the Effective Time the issuer became a wholly owned indirect subsidiary of the buyer and all outstanding common stock was converted into a fixed cash payment of $23.00 per share. Deferred Stock Units and Phantom Stock previously outstanding were likewise converted into cash rights payable under the award terms and Section 409A. The filing is consistent with standard post-merger insider reporting and documents that the reporting director no longer holds publicly traded common shares following the transaction.
