Mirion Technologies (MIR) has drawn fresh attention after reporting second quarter 2026 results and reaffirming full year revenue growth guidance of about 22% to 24%, supported by foreign exchange and acquisition related tailwinds.

Despite reaffirmed guidance and solid top line progress, Mirion Technologies’ recent share price performance has been weak, with the stock down 29.54% on a year to date basis while the 3 year total shareholder return is 122.68%. This suggests earlier optimism has cooled even though long term holders still sit on sizeable gains.

Bulls see Mirion Technologies as a growing radiation safety specialist that the market has punished too harshly after its earnings update. Bears point to modest net income and past misses. Which side does today’s valuation really support?

Most Popular Narrative: 39.8% Undervalued

The most followed narrative values Mirion Technologies at $27.90 per share compared with the last close of $16.79, which frames the current debate over how much growth is already priced in.

Continued rollout of new digital platforms, such as the Vital and Apex-Guard software, along with the Certrec acquisition, positions Mirion to capture premium pricing, expand its software mix, and unlock operating leverage. This combination potentially supports stronger margins and more durable earnings as a larger share of revenue comes from higher value recurring and compliance based solutions.

Curious what has to happen for that $27.90 fair value to hold up? The narrative leans heavily on faster earnings growth, rising margins, and a richer software and services mix. The exact forecasts behind that story may surprise you.

Result: Fair Value of $27.90 (UNDERVALUED)

However, investors still need to watch for slower nuclear project activity or tougher integration of acquisitions, which could pressure Mirion Technologies’ growth narrative and earnings expectations.
