Insights

Corporate Governance Analyst

Mubadala group discloses concentrated shared ownership of GLOBALFOUNDRIES.

The Schedule 13G/A Amendment identifies 423,042,773 shares tied to Mubadala-related reporting persons and cites the issuer's statement that 549,072,416 Ordinary Shares were outstanding as of March 13, 2026. This establishes the group's >50% position via shared voting/dispositive power.

Key dependencies include the issuer's prospectus supplement cited for the outstanding share count and the post-March 31, 2026 disposal of 1,469,017 shares by Mubadala Technology Investment Company, which slightly alters raw counts; subsequent filings will show any further movement.

Securities Counsel

Disclosure aligns with Rule 13d-1 reporting for passive/beneficial ownership aggregation.

The joint filing and Exhibit 1 (Agreement of Joint Filing) document the reporting group and allocate shared voting and dispositive powers. The cover-page comments reference a prospectus supplement filed under Rule 424(b)(7) as the source of the 549,072,416 outstanding shares figure.

Filing notes a post-period disposition of 1,469,017 shares; legal watchers should confirm whether further amendments are required if additional movements occur.

Schedule 13G/A regulatory

"Amendment No. 2 to Schedule 13G/A"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
