ATRI · Instruments & Medical Devices · NASDAQ · in our data December 14, 1972 to August 20, 2024 (51.7 years)

Our price history begins on December 14, 1972, and Atrion Corp was already trading then; how long before that, our data does not say. At its peak, on April 9, 2019, the market valued it at $1.7 billion. It left the market when it was bought or merged, last trading at $459.92, -46.8% from its split-adjusted high. Holders got whatever the deal paid, which is not in our price data.

Share prices are adjusted for splits and other share changes, so the high and the last price compare like for like; the peak market value is as it was on the day. The return covers the trading days in our data only: it does not include what holders received, or lost, after the last trade (a merger payout, a bankruptcy), and it does not reach back before 1972.
