GlobalFoundries Net Worth / Company Profitability
GlobalFoundries reported full-year 2024 revenue of $6.75 billion, down approximately 9% from $7.39 billion in fiscal 2023. The company posted a GAAP net loss of $262 million in 2024, compared to net income of $1.018 billion in 2023, largely due to a $935 million impairment charge on legacy production assets at its Malta, New York facility. On a non-IFRS basis, the company remained profitable with adjusted net income of $870 million. As of February 2026, GlobalFoundries’ market capitalization stands at approximately $25 billion, with shares trading around $46 on Nasdaq.

| Market Capitalization | ~$25 billion | ▲ Stable |
| Adjusted Free Cash Flow | $1.107 billion | ▲ Positive |
Note: The FY 2024 net loss was primarily driven by a one-time $935 million impairment charge on long-lived assets at the Malta, NY facility related to legacy production capacity. Excluding this non-cash charge, the company remained profitable on an adjusted basis. Under Caulfield’s leadership, GlobalFoundries achieved sustainable profitability and generated over $1 billion in adjusted free cash flow in 2024.
