Lumexa Imaging Holdings, Inc.
A provider of outpatient diagnostic imaging, Lumexa Imaging runs a network of hundreds of MRI, CT, PET, X-ray, ultrasound, and mammography centers across a dozen states. It was born in 2018 as US Radiology Specialists, a partnership between the physician-owned Charlotte Radiology practice and private equity firm Welsh, Carson, Anderson & Stowe, and it rebranded as Lumexa in July 2025. The name blends "Lum-" for illumination and "-exa" for exceptional scale.

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: +65.0K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
