Meridian Small Cap Growth Fund stated the following regarding Mirion Technologies, Inc. (NYSE:MIR) in its second quarter 2025 investor letter:

"Mirion Technologies, Inc. (NYSE:MIR), a global leader in ionizing radiation measurement and detection, provides critical technologies for the nuclear power and medical sectors. Mirion’s revenues are largely recurring or replacement in nature and supported by strong secular trends, providing valuable transparency and predictability. The stock rebounded in the quarter following its sharp January sell-off tied to DeepSeek-related volatility—an event we viewed as unwarranted given Mirion’s recurring revenue model and supporting tailwinds. The stock gained further ground following progress in its Westinghouse partnership, which would add to its installed base, and amid discussions of potential new nuclear power facilities in the U.S. and Europe. We trimmed our position during the period as the share price appreciated."
