Why Does MIR Stock Spark Debate?
With its technology protecting workers in over 130 countries and equipment used in 80% of cancer centers worldwide, Mirion Technologies (NYSE: MIR) provides radiation detection, measurement, and monitoring solutions for medical, nuclear energy, defense, and scientific research applications.
Two Things to Like:
1. Skyrocketing Revenue Shows Strong Momentum
Examining a company’s long-term performance can provide clues about its quality. Even a bad business can shine for one or two quarters, but a top-tier one grows for years. Luckily, Mirion’s sales grew at an impressive 9.9% compounded annual growth rate over the last four years. Its growth surpassed the average business services company and shows its offerings resonate with customers. 
2. Increasing Free Cash Flow Margin Juices Financials
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
As you can see below, Mirion’s margin expanded by 4.4 percentage points over the last five years. The company’s improvement shows it’s heading in the right direction, and we can see it became a less capital-intensive business because its free cash flow profitability rose while its operating profitability fell. Mirion’s free cash flow margin for the trailing 12 months was 9.7%.
One Reason to be Careful:
Previous Growth Initiatives Haven’t Paid Off Yet
Growth gives us insight into a company’s long-term potential, but how capital-efficient was that growth? Enter ROIC, a metric showing how much operating profit a company generates relative to the money it has raised (debt and equity).
Although Mirion has shown solid business quality lately, it struggled to grow profitably in the past. Its five-year average ROIC was negative 0.5%, meaning management lost money while trying to expand the business.
Final Judgment
Mirion’s merits more than compensate for its flaws, and with its shares topping the market in recent months, the stock trades at 28× forward EV-to-EBITDA (or $21.57 per share). Is now a good time to buy? See for yourself in our full research report, it’s free.
