Dear Fellow Stockholders:

We are pleased to invite you to join us for Mirion’s 2025 Annual Stockholders' Meeting. The meeting is scheduled to take place virtually on Thursday, May 15, 2025 at 10:00 a.m. (Eastern Time), via live webcast at www.virtualshareholdermeeting.com/MIR2025.

Mirion delivered historic performance in 2024. For example, we reported record 2024 revenue of $860.8 million, or 7.5% better than 2023. Margins also expanded in 2024, showcasing the strong operating leverage of our business.

We also took significant steps to improve our capital structure. During the year, we redeemed all outstanding warrants, vested all founders’ shares, and repriced existing debt. We entered 2025 with a much simpler and cleaner capital structure.

We unveiled updated long-term targets at our December 2024 Investor Day to help investors quantify the momentum building in our business. The updated targets are driven by our strong exposure to favorable super trends underway in Nuclear Power and Cancer Care.

Commercial nuclear power represented approximately 37% of Mirion's 2024 revenue and is undergoing a global renaissance. While there are many factors supporting nuclear market growth, so-called hyperscalers have commanded the most attention, as they look to secure baseload, carbon-free electrical generating capacity to meet the growing demand from data centers and artificial intelligence. Mirion serves the entire nuclear life cycle, from construction to decommissioning, and offers a full suite of hardware, software and services solutions.

Cancer care represented approximately 26% of Mirion's 2024 revenue. This market is also characterized by attractive fundamentals - driven by aging developed-country demographics and emerging market needs. In addition, there is a revolution underway in the use of therapeutic radioisotopes.

2025 is shaping up to be another transformative year. Mirion is a "category of one" as the only pure play in the detection, measurement, and analysis of ionizing radiation. As a result, we are well-positioned to support the exciting evolution of nuclear power and cancer care markets. We provide the mission critical, compulsory solutions our customers need to operate in highly-regulated industries with high cost of failure.

On behalf of our employees and Board of Directors, we thank you for your support of Mirion. We encourage you to cast your vote on the items up for vote at our 2025 Annual Stockholders’ Meeting, which are laid out in the accompanying proxy statement along with voting instructions.

Respectfully,

Thomas D. Logan
