GlobalFoundries Inc. (NASDAQ: GFS) reported an insider sale on April 15, 2026, when Chief Business Officer Michael James Hogan sold 1,800 ordinary shares at $48.31 apiece, for a total of $86,958, according to a Form 4 filing with the Securities and Exchange Commission.
The filing shows that the sale reduced Hogan's direct stake to 18,995 shares. The same day he also made a separate gift of 150 shares.
Market context in the filing notes the company's stock subsequently rose to $54.14 and is trading near a listed 52-week high of $51.01, with shares up nearly 59% over the past year. An InvestingPro analysis cited in the filing characterizes the stock as appearing overvalued at current levels and points to more detailed findings in the platform's Pro Research Report.
The Form 4 includes disclosures about a lock-up agreement tied to an offering conducted by the issuer's majority shareholder. The reporting person remains subject to that lock-up, which expires on May 10, 2026. The filing states the sale and the gift were permissible under an exemption in the lock-up agreement and that both transactions were effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person prior to the offering.
The insider transaction comes as GlobalFoundries has pursued legal action against Tower Semiconductor Ltd. in two U.S. venues - the U.S. International Trade Commission and the United States District Court for the Western District of Texas - alleging patent infringement. The complaint asserts Tower is utilizing GlobalFoundries' patented manufacturing process technologies without authorization and references 11 U.S. patents.
Separately, GlobalFoundries' largest shareholder, Mubadala Technology Investment Company, priced a secondary offering of 20 million ordinary shares at $42.00 per share. The offering was sold by Mubadala, not by GlobalFoundries, and the company will receive no proceeds from the transaction. The filing states the offering drew demand approximately four times the size of the $840 million sale.
In another corporate development noted in the filings, USA Rare Earth appointed Dr. Thomas Caulfield, the Executive Chairman of GlobalFoundries, to its Board of Directors. Dr. Caulfield previously served as President and Chief Executive Officer of GlobalFoundries and led the company through its initial public offering in 2021.
These disclosures combine insider trading activity with concurrent corporate events - litigation, a large secondary share placement by the majority shareholder, and a director appointment - that are recorded in public filings and related notes referenced in the Form 4.
