Why Mirion Technologies (MIR) Stock Is Down Today

Investivoq PriceTracker

Mirion Technologies (MIR) is down 6.7% today. Here is some analysis on what might have caused this price movement.

Analysis: The drop does not appear to be tied to a fresh company-specific negative announcement on November 11, 2026. This could be because investors are still digesting a mixed late-October update: Mirion posted strong revenue and order growth and lifted its sales outlook, but it also trimmed parts of its profitability and adjusted EPS outlook, which can pressure shares after a rally.

Details:

In its third-quarter update, Mirion said organic revenue rose 6.5% and orders excluding acquisitions jumped 62%, helped by a 105% increase in nuclear power-related orders.

The company raised its 2026 revenue growth outlook to about 24% to 25% and increased organic revenue growth guidance to about 7% to 8%.

At the same time, Mirion lowered its adjusted EBITDA margin outlook to about 24.7% to 25.2% from 25.0% to 26.0%, and narrowed adjusted EPS guidance to about $0.50 to $0.54 from $0.48 to $0.55.

Management said at its November 10 conference appearance that demand tied to the installed nuclear base is accelerating and could support years of upgrade activity, so today’s weakness may reflect profit-taking or near-term positioning rather than a newly disclosed operating problem.
