Shareholders
5
Five shareholders are currently on record for ATRION CORPORATION, reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Kayne Anderson Rudnick Investment Management LLC, holding 15.8% — the largest recorded stake — followed by Neuberger Berman Group, LLC at 14.4%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Director of ATRION CORPORATION currently on record is FRANKS GUY; five officers are currently on record for ATRION CORPORATION, filed with Texas Secretary of State — SOSDirect.
The register reports 11 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at ATRION CORPORATION sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
ATRION CORPORATION sits 1 level below its ultimate parent, Nordson Corporation, registered in United States. 4 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to Nordson Corporation is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by ATRION CORPORATION's own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 4 subsidiaries span United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
