Mirant Corporation
A maker of radiation detection, measurement, and monitoring tools, Mirion Technologies equips nuclear power plants, defense labs, and cancer centers worldwide. Its products and services, like dosimetry monitoring and quality-assurance software, protect workers, patients, and facilities from invisible radiation. Formed in 2005 by stitching together several decades-old radiation-safety brands, the company kept growing through acquisitions. Fun fact: it redesigned detection devices for first responders after learning standard lab buttons were too small to press while wearing emergency gloves.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over all recorded history: -11.42M shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
