Mirion Technologies (MIR) Raised Revenue Outlook, Is The Stock Still Cheap?

Most Popular Narrative: 22% Undervalued
Mirion Technologies is priced at $18.37 while the most followed narrative anchors fair value at $23.55, which points to a sizeable gap that analysts are tying to nuclear demand, software mix and margin rebuilding.
The accelerating global shift toward expanded nuclear power generation, coupled with rising capital budgets for modernization, life extensions, and increased capacity of the existing reactor fleet, is described as a driver of sustained double-digit organic revenue growth and an expanding higher-margin installed base business for Mirion in coming years. Commentators also highlight strong momentum in advanced nuclear projects, including utility-scale new builds and rapid activity in the small modular reactor (SMR) market, which has materially broadened Mirion's pipeline of large, multi-year opportunities and created potential for significant step-changes in future order intake, backlog, and top-line revenue.
See why 8 investors see Mirion Technologies as 22% undervalued.
Result: Fair Value of $23.55 (UNDERVALUED)
