The insider sale comes after a choppy stretch for Mirion, with a 30 day share price return of minus 12.36% but a strong year to date share price return of 47.87% and robust multi year total shareholder returns. This suggests that longer term momentum remains intact.

With shares still trading at a roughly 24% discount to analyst targets but with little apparent margin to some intrinsic value estimates, investors now face a key question: is Mirion a mispriced growth story, or is the market already baking in its next leg higher?
