Mubadala's repeated large-scale selling (28.8M shares in Q1 2026, now 22M more) signals a deliberate reduction of its stake. Traders should monitor for actual execution of this 144 notice and watch for further filings. The overhang from a $2B potential block trade could pressure GFS shares near-term, especially given the stock's 50% analyst bullish rating (not overwhelmingly positive). Consider hedging or reducing exposure until the selling cadence becomes clear.

Executive Summary
Mubadala Investment Co. PJSC, the controlling shareholder of GlobalFoundries, filed a Form 144 on May 26, 2026, indicating intent to sell 22,000,000 ordinary shares (worth approximately $1.98B at the filing date). This represents about 4% of shares outstanding (based on the 378M shares held by the seller). The filing follows a prior sale of 28.8M shares in March 2026 and an underwriter option exercise in April 2026, signaling ongoing monetization by the majority owner.
Key Facts
- Mubadala Investment Co. PJSC (controlling shareholder) filed Form 144 to sell 22,000,000 ordinary shares of GFS.
- Proposed sale value is approximately $1.98 billion based on the filing date.
- The seller directly holds 378,273,074 shares, so the proposed sale represents ~5.8% of their position.

Financial Impact
Up to $1.98 billion in potential selling pressure from the controlling shareholder, representing ~4.6% of GFS's $47.7B market cap.
Risk Factors
- Actual sale of 22M shares could create significant downward price pressure.
- Mubadala may continue to sell additional shares in future tranches, extending the overhang.
- The large block may be executed via an underwritten secondary offering, which could be priced at a discount.
- Insider selling by the controlling shareholder may signal reduced long-term commitment or a view that current valuation is full.
