Rege Sheila reported acquisition or exercise transactions in this Form 4 filing.

Mirion Technologies, Inc. approved a special one-time grant of performance-vesting stock options to Founder, Chairman and CEO Thomas Logan. He received a target of 2,500,000 performance stock options with a seven-year term, split into two tranches measured over three- and four-year periods.
Vesting depends on both his continued service and the Company’s total shareholder return relative to the Russell 2000 (excluding financial services and insurance). Payout ranges from 0% to 150% of target, with threshold performance at the 60th percentile and a one-year holding period after vesting. Mirion expects non-cash charges from this award to be reflected in its next earnings guidance.
