• GlobalFoundries is not participating in the share sale and won’t collect any funds from the transaction
• Underwriters received a 30-day greenshoe option to purchase an additional 3 million shares

• The share buyback operates under a $500 million authorization granted by the board in February 2026

Shares of GlobalFoundries (GFS) tumbled 5.45% following the announcement that Mubadala Technology Investment Company, its primary stakeholder, completed a secondary offering of 20 million shares at $42.00 apiece on March 11, 2026.

GLOBALFOUNDRIES Inc., GFS

The $42.00 offering price represented a markdown from the prevailing market price of $44.09 when the deal was priced. Nevertheless, GFS shares remain elevated by approximately 39% over the preceding six-month period, despite Tuesday’s selloff.

Mubadala Technology Investment Company operates as a fully owned entity under the Abu Dhabi-based Mubadala Investment Company PJSC. As GlobalFoundries’ dominant shareholder, Mubadala stands as the exclusive selling party in this stock transaction.

The semiconductor manufacturer is staying on the sidelines of this offering. GlobalFoundries will not capture any proceeds from the share sale.

The deal structure provides underwriters with a 30-day greenshoe provision allowing them to acquire up to 3 million additional shares at the same offering price, minus underwriting discounts. This option represents a 15% increase over the base offering of 20 million shares.

$300M Buyback Running Alongside the Offering

To mitigate the dilutive effects of the offering, GlobalFoundries committed to acquiring $300 million of its own shares directly from the underwriting syndicate. The company’s repurchase price will match the underwriters’ purchase price in the secondary sale.

The share repurchase program will draw entirely from GlobalFoundries’ existing cash holdings. This buyback operates within a broader $500 million share repurchase program that received board approval during February 2026.

The secondary offering is scheduled to finalize on March 13, 2026. While the buyback’s completion depends on the offering closing, the offering itself proceeds independently of the buyback’s completion.

J.P. Morgan and Morgan Stanley serve as joint book-running managers for the transaction. BofA Securities, Citigroup, and Goldman Sachs round out the syndicate as active book-runners.
