MDXG in this quarter's filings
Concentration check: the largest reported position, Essex Woodlands Management, Inc. with 28,195,249 shares, is 24.2% of all shares reported for MDXG this quarter. The five largest reporting managers together account for 53.7% of the reported total, so the headline total is dominated by a handful of large managers.
Reported quarter-over-quarter change: the reporting-manager count fell by 11 versus the quarter ended 2026-03-31, and reported shares moved +3.31% (+3,740,992 shares). That is a comparison of two filing snapshots, not a record of trades on any single day.
Shares-outstanding cross-check: reported 13F shares equal 78.7% of the issuer share count used at the publication gate (148,119,083 shares, issuer period ended 2026-06-30). The gate publishes a ticker only when that relationship is plausible; lending chains can push reported totals above a simple ownership share, which is why the figure is a sanity check and not an ownership percentage.
