Mirion Technologies (MIR): Valuation Insights Following S&P Index Additions and Rising Investor Attention

If you have been following Mirion Technologies (NYSE:MIR), you may have noticed a recent flurry of headlines. Mirion has been added to several major S&P indices in quick succession, including the S&P 1000, S&P 600, S&P Composite 1500, and the S&P 600 Information Technology sector. For many investors, these moves are more than just technical reshuffling; they often translate directly into increased buying by index funds and heightened attention from the broader market.

Mirion’s entry into these indices comes after a year of steady upward momentum. Over the last twelve months, shares have soared by 129%, with most of that gain accelerating in recent months. Short-term performance has been strong as well, suggesting that investor sentiment is building, potentially thanks to both broader tech-sector trends and interest triggered by these index additions. With annual revenue and net income growth both moving higher, the fundamental side is also showing improvement, though those numbers are coming off a lower base.

So, the question now is whether the recent rally leaves more room to run. Does Mirion’s valuation still offer upside, or are market expectations already reflecting the company’s future prospects?

Most Popular Narrative: 0.5% Undervalued

According to the most widely followed narrative, Mirion Technologies is currently considered slightly undervalued, trading just below fair value when factoring in discount rates and expected profit expansion over the next three years.

"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 likely to drive sustained double-digit organic revenue growth and expand Mirion's higher-margin installed base business in coming years. Strong momentum in advanced nuclear projects, including utility-scale new builds and rapid activity in the small modular reactor (SMR) market, has materially broadened Mirion's pipeline of large, multi-year opportunities. This creates potential for significant step-changes in future order intake, backlog, and top-line revenue."
