Why Mirion Technologies Stock Is Back In Focus After A New Partnership

Mirion Technologies (MIR) is back on investor radar after Perma-Fix Environmental Services announced a partnership with the company under the Small Business Administration’s Mentor Protégé Program focused on U.S. nuclear cleanup projects.

The collaboration targets advanced waste characterization, radiological measurement, processing, and disposal support tied to Department of Energy cleanup work. For Mirion Technologies stock, the key question is how this relationship could influence long term project visibility and revenue mix within its Nuclear & Safety segment.

The partnership headlines arrive as Mirion Technologies trades at US$15.89, with a 1 day share price return of 1.86% and a 7 day share price return of 5.44%. This contrasts with a year to date share price decline of 33.32%, while the 3 year total shareholder return of 104.77% highlights how long term holders have still seen strong gains even as recent momentum has softened.

Bulls point to Mirion Technologies’ growing nuclear cleanup exposure and recent partnership buzz. Bears highlight the share price slide since the start of the year. Which side does the current valuation evidence support next?

Most Popular Narrative: 35.9% Undervalued

The most followed narrative on Mirion Technologies suggests a fair value of $24.80 per share, which sits well above the recent close at $15.89. That gap rests on a specific earnings and margin roadmap that analysts believe the business can reach over the next few years.

Continued rollout of new digital platforms, such as the Vital and Apex-Guard software, along with the strategic Certrec acquisition (bringing SaaS-based, AI-enabled compliance tools), positions Mirion to capture premium pricing, drive software mix expansion, and unlock operating leverage, benefitting margins and long-term earnings potential.

Curious what it would take for Mirion Technologies to support that higher fair value? The narrative leans on faster earnings growth, richer margins, and a future profit multiple that is usually reserved for higher growth stocks. The full story ties those assumptions together into one valuation path.

Result: Fair Value of $24.80 (UNDERVALUED)

However, Mirion Technologies still faces concentration in nuclear markets and potential acquisition integration issues that could challenge the earnings and valuation path behind that 35.9% undervalued view.

Another View: Mirion Technologies Looks Expensive On Sales

The first narrative framed Mirion Technologies as 35.9% undervalued based on analyst earnings and fair value work. A simpler check using the P/S ratio points in the opposite direction. Mirion trades on 3.8x sales, above the US Electronic industry at 3x, peers at 2.5x, and a fair ratio of 3.1x. That premium implies less margin for error if growth or margins fall short of expectations, so how comfortable are you paying up on this metric?
