Radnet, Inc.
A U.S. outpatient diagnostic imaging company, RadNet operates roughly four hundred multi-modality centers across nine states, where patients get MRIs, CT scans, PET scans, and mammograms. Founded in 1981 by six Los Angeles doctors (including current CEO Howard Berger), it began by billing for radiology groups before opening its first imaging center across from Cedars-Sinai. Its name blends "radiology" and "network," and its DeepHealth arm builds AI tools for reading scans, born from a 2020 acquisition of a Cambridge mammography-AI startup.

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 the last year: -236.6K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
