Is Mirion a Smart Investment After 115% Rally and Recent Industry Partnerships in 2025?

Simply Wall St

If you have been following Mirion Technologies, chances are you have noticed just how attention-grabbing its recent stock moves have been. Investors watching from the sidelines can’t help but wonder if now is the right time to get in, take some profits, or simply watch what happens next. Over the last year, Mirion has more than doubled, boasting a 115.0% gain. If you zoom out further, the stock is up an eye-watering 218.1% over three years. Even the past year-to-date has seen a stellar 40.4% jump, hinting at renewed optimism in the radiation measurement and safety sector, possibly fueled by ongoing shifts in the global energy landscape and heightened focus on nuclear safety.

Of course, not all short-term movements have been upward. The last week saw a slight pullback with Mirion giving up 2.8%, which may reflect traders catching their breath after such strong momentum. The 30-day picture, though, is still firmly positive with a 15.9% increase, suggesting long-term bulls are holding strong despite some jittery sessions.

What about Mirion’s value right now? Our standard valuation checks score the company at zero out of six, meaning it isn’t flagging as undervalued by any of the main criteria we track. But as anyone who’s spent time in the markets knows, numbers and ratios only tell part of the story. Let’s dig a little deeper into the valuation methods behind that score. Then, we’ll consider an even better way to gauge what Mirion is really worth.

Mirion Technologies scores just 0/6 on our valuation checks. See what other red flags we found in the full valuation breakdown.

Approach 1: Mirion Technologies Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) model estimates a company’s value by projecting its future free cash flows and discounting them back to today’s dollars. This method attempts to capture the present value of potential profits that Mirion Technologies could generate over the long term.

For Mirion Technologies, the most recent reported Free Cash Flow stands at $82.0 Million. Analyst estimates expect this number to climb sharply, reaching approximately $148.95 Million by the end of 2026. Although analysts provide forecasts for the first five years, the model extends these projections and anticipates Free Cash Flow could reach about $347.7 Million by 2035 based on continued growth.

When running these projections through the DCF model using the 2 Stage Free Cash Flow to Equity approach, the estimated intrinsic value for Mirion Technologies comes out to $20.72 per share. However, compared to the latest share price, this figure implies the stock is currently trading 14.7% above its calculated fair value. In other words, Mirion appears moderately overvalued according to this method.

Result: OVERVALUED

Approach 2: Mirion Technologies Price vs Sales

The Price-to-Sales (P/S) ratio is often a preferred valuation tool for companies like Mirion Technologies, especially when earnings are volatile or in the early stages of ramping up. This multiple lets investors assess how much they are paying for each dollar of sales, which can be useful for profitable businesses in fast-evolving industries.

Growth expectations and risk both influence what a "normal" P/S ratio should be. High growth companies often command a premium multiple, while riskier or slower-growing firms trade at a discount. When we look at Mirion's current P/S of 5.61x, it is notably higher than both its peer average of 3.24x and the broader electronic industry average of 2.48x. On face value, this could suggest Mirion is priced at a premium versus competitors.

However, Simply Wall St's “Fair Ratio” refines this comparison by factoring in Mirion's unique growth prospects, profit margins, industry conditions, and even market cap and specific risks. This custom benchmark sets Mirion’s fair P/S at 3.09x, providing a more accurate yardstick than a straight comparison to peers or industry averages. Since Mirion’s current P/S ratio is materially above this Fair Ratio, the valuation suggests the stock is trading at a premium that does not quite line up with its underlying fundamentals.

Result: OVERVALUED
