Kuwait Investment Authority reports a passive 4.1% stake in Mirion.

Kuwait Investment Authority (KIA) discloses beneficial ownership of 10,171,591 Mirion Class A shares, equal to 4.10% of the class as of January 19, 2026. KIA reports sole voting and dispositive power over all these shares and no shared authority, so decisions over this block rest entirely with KIA.

The stake’s percentage is calculated using 247,821,635 Class A shares outstanding as of October 22, 2025. KIA’s position has edged up in absolute terms from 10,000,000 shares at December 31, 2022 to 10,171,591 shares at December 31, 2024, though the filing emphasizes current levels rather than the path of accumulation.

KIA explicitly certifies that the holdings were not acquired and are not held for the purpose of changing or influencing control of Mirion, characterizing this as a passive investment. From a governance and valuation perspective, this looks like routine institutional ownership disclosure rather than a thesis-changing event.
