The offer was structured as a generous cash-and-stock package designed to win over shareholders:

• €9.4 billion in cash, representing €5.05 per share .
• 0.77 shares of a new UMG entity for each existing share held.

The total consideration was valued by Pershing Square at an estimated €30.40 per share, which translated to a roughly 78% premium over UMG’s unaffected share price before the bid became public .

To fund the cash portion, Pershing Square laid out a multi-source capital plan: roughly €2.5 billion from its own funds, approximately €5.4 billion in new investment-grade debt, and about €1.5 billion from the sale of UMG’s Spotify stake, with a portion of that earmarked for UMG’s artists .

A central feature of the proposal was relisting UMG’s stock. The plan envisioned moving the company’s primary listing from the Euronext Amsterdam to the New York Stock Exchange, a shift Ackman argued would unlock value by attracting a broader U.S. investor base .

The May Rejection: "Significantly Undervalues UMG"

UMG’s board of directors took roughly seven weeks to deliberate, formally rejecting the proposal on May 29, 2026. The decision was unanimous .

The board’s official statement, issued after a review assisted by outside financial and legal advisors, was blunt. It called the offer "not in the best interests of UMG, its shareholders, artists, songwriters, employees and other stakeholders," and concluded that the proposal fundamentally "significantly undervalues UMG and its future prospects" .

For a board to reject a 78% premium, the conviction around future value creation had to be exceptionally strong. The statement pointed to a consensus among shareholders backing the board’s decision .

The Immediate Exit: Selling 80.6 Million Shares

Pershing Square’s response was swift. On June 3, 2026, reports confirmed the fund was moving to sell its entire remaining stake in UMG. The sale involved approximately 80.6 million shares and was structured as an overnight placing to institutional investors .

Initial reports at the time pegged the expected gross proceeds at roughly $1.6 billion, though the exact final price per share and total haul were still being finalized in those early reports . No immediate confirmation surfaced of a simultaneous share buyback by UMG as part of this specific exit.

The sell-off completely unwound Pershing Square’s position, closing the book on a major holding that had been the firm’s largest position for years .

The Five-Year UMG Investment, by the Numbers

Pershing Square’s relationship with UMG began as a long-term conviction play, building a stake before the company’s public debut.

• Original Entry (2021): The firm acquired roughly 10% of UMG from the French media conglomerate Vivendi leading up to the company’s September 2021 listing. The transaction was priced at a premium based on an enterprise value of €35 billion for 100% of the company .
• Gradual Trimming: Over the years, Pershing Square steadily reduced its holdings. In January 2025, it distributed approximately 2.6% of UMG stock to its own limited partners . By March 2025, Pershing Square sold an additional 2.7% stake—about 50 million shares at €26.60 per share—raising more than $1.4 billion .
• Peak Position: After the early 2025 distributions, Pershing Square still reported owning 7.6% of UMG . At its height, UMG had constituted around 27% of the firm's portfolio .

Although a profitable investment overall, a precise headline figure for Pershing Square’s total gross profit or IRR across the full five-year period has not been reported. Entering at a €35 billion enterprise valuation and selling down at richer premiums clearly generated strong returns, but the exact aggregate gain remains undisclosed. The final overnight sale of its remaining shares effectively drew a line under a five-year venture that ultimately fell short of its full-takeover aspirations.
