| About Mirion Technologies Inc |
| Mirion Technologies, Inc. is a global provider of radiation detection and monitoring solutions for the medical, nuclear, defense, and research sectors. The company has two main segments: Medical and Technologies. The Medical segment offers products and services for radiation therapy and personal dosimetry, including solutions for calibrating treatment machines and monitoring staff radiation exposure. The Technologies segment focuses on defense and nuclear energy, providing reactor safety systems and radiological measurement tools. This comprehensive range of offerings positions Mirion as a vital player in ensuring safety and accuracy across critical industries. We show 20 historical shares outstanding datapoints in our MIR shares outstanding history coverage, used to compute MIR market cap on those dates. Understanding the changing numbers of shares outstanding, the changing share price, and the resulting changing MIR market cap history over the course of time is important for investors interested in comparing MIR's market cap history versus its peers. Many "beginner" or "novice" investors will look at one stock trading at a price of $10 per share and another trading at a price of $20 per share and think the latter company is worth twice as much. Of course, that is a completely meaningless comparison without also knowing how many shares outstanding there are for each of the two companies, and then calculating their respective market caps. Comparing the share price of MIR versus a peer is one thing; comparing MIR market cap versus a peer is a completely different story. Furthermore, via fluctuation both in per-share price and in the number of shares outstanding (via issuance of new shares over time, the repurchase of existing shares), the market cap for a company like MIR can fluctuate over the course of history. With this page we aim to empower investors researching MIR by allowing them to research the MIR market cap history. |
