Insights

M&A Specialist

TL;DR Completed acquisition: Ferrero closed the merger and cashed out public shares at $23.00 each.

The filing documents a standard acquisition-close disclosure: Ferrero International S.A. completed its acquisition through a merger on September 26, 2025, and per the Merger Agreement each outstanding share (subject to limited exclusions) was cancelled and converted into $23.00 cash. The W.K. Kellogg Foundation Trust disposed of 13,505,159 shares and reports zero remaining beneficial ownership. This is a material corporate control change that effects ownership, liquidity, and the public float by converting equity into cash consideration.

Corporate Governance Expert

TL;DR Trustees disclosed a full cash-out of trust holdings following the merger; beneficiaries receive $23.00 per share.

The Form 4 reflects trustee action consistent with the Merger Agreement: the Trust’s large block of shares was cancelled for cash consideration, and the reporting signatures indicate the corporate trustee executed under power of attorney. The filing confirms the Trust no longer holds beneficially owned common stock after the transaction, a governance and stewardship outcome that transfers control to the acquirer and resolves potential conflicts tied to a large institutional holder.
