**Dear Fellow Stockholders:**

We are pleased to invite you to join us for Mirion's 2026 Annual Stockholders' Meeting. The meeting is scheduled to take place virtually on Wednesday, May 13, 2026 at 10:00 a.m. (Eastern Time), via live webcast at www.virtualshareholdermeeting.com/MIR2026.

Momentum continues to build broadly across the nuclear power and cancer care end-markets. In the nuclear power market, power availability is becoming increasingly critical to support data center and artificial intelligence infrastructure. Similarly, in cancer care, structural factors such as an aging global population and elevating standards of care in developing markets are driving increased demand for cancer care.

In 2025 we booked a record $1+ billion of orders. This reflects a 26% increase compared to 2024, driven by both the tailwinds in our key vertical markets and our augmented capabilities. Notably, 2025 organic revenue from both our Nuclear Power and Nuclear Medicine end-markets grew double-digits.

2025 also reflected progress on our stated goal to increase our nuclear power exposure. In July, we acquired Certrec, and in December we closed on the acquisition of Paragon Energy Solutions. Both acquisitions enhance our nuclear power exposure and provide opportunities across the lifespan of both large-scale nuclear reactors and the emerging class of advanced and small modular reactors. Pro-forma commercial nuclear power revenue is now approximately 47% of Mirion revenue, up significantly from 37% prior to these acquisitions.

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 2026 Annual Stockholders' Meeting, which are laid out in the accompanying proxy statement along with voting instructions.

Respectfully,

Holders of our common stock as of the close of business on March 16, 2026, the record date, may vote at the Annual Meeting. As of the record date, there were 244,394,562 shares of our Class A common stock and 5,864,555 shares of our Class B common stock outstanding. Each share of Class A and Class B common stock is entitled to one vote. Holders of our Class A common stock and Class B common stock will vote as a single class on all matters described in this proxy statement. References to our common stock shall be deemed to refer to our Class A and Class B common stock, collectively.

**What is the difference between holding shares as a stockholder of record and as a beneficial owner?**

If your shares are registered directly in your name with our transfer agent, Continental Stock Transfer & Trust Company, you are considered the stockholder of record with respect to those shares, and the Notice of Internet Availability of Proxy Materials (the "Notice") was sent directly to you by us.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the "beneficial owner" of shares held in street name. The Notice and, upon your request, the proxy materials were forwarded to you by your broker, bank or other nominee who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your bank, broker or other nominee on how to vote your shares by following their instructions for voting.

 Questions and Answers

If you are a beneficial owner of shares held in street name, you should have received from your bank, broker or other nominee instructions on how to vote or instruct the broker to vote your shares, which are generally contained in a "voting instruction form" sent by the broker, bank or other nominee. Please follow their instructions carefully. Beneficial owners generally may vote:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Via the Internet before the Annual Meeting.*** You may vote by proxy via the Internet at www.proxyvote.com up until 11:59 p.m Eastern Time Tuesday, May 12, 2026. Follow the directions on the voting instruction form provided to you by your broker, bank or other nominee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• By Telephone.*** You may vote by proxy by calling 1-800-690-6903 up until 11:59 p.m Eastern Time Tuesday, May 12, 2026. Have the voting instruction form provided to you by your broker, bank or other nominee in hand when you call and follow the directions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• By Mail.*** You may vote by proxy by filling out the voting instruction form and returning it in the envelope provided to you by your broker, bank or other nominee to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***• Via the Internet during the Annual Meeting.*** In order to vote during the Annual Meeting you must go to www.virtualshareholdermeeting.com/MIR2026 and enter the 16-digit control number found in the proxy materials. If you decide to attend the Annual Meeting, you will be able to vote using the link above, even if you have previously voted by Internet, Telephone or Mail.

If you received more than one Notice of Internet Availability of Proxy Materials or proxy card, then you hold shares of Mirion common stock in more than one account. You should vote via the Internet, by telephone, by mail or in person for all shares held in each of your accounts.

**If I submit a proxy, how will it be voted?**

When proxies are properly signed, dated and returned, the shares represented by the proxies will be voted in accordance with the instructions of the stockholder. If no specific instructions are given, you give authority to Thomas D. Logan or Emmanuelle Lee to vote the shares in accordance with the recommendations of our Board as described above. If any director nominee is not able to serve, proxies will be voted in favor of the other nominee and may be voted for a substitute nominee, unless our Board chooses to reduce the number of directors serving on our Board. If any matters not described in this Proxy Statement are properly presented at the Annual Meeting, then the proxy holders will use their own judgment to determine how to vote the shares. If the Annual Meeting is adjourned, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy.

**Can I change my vote or revoke my proxy?**

Yes. If you are a stockholder of record, you can change your vote or revoke your proxy before it is exercised by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Written notice to our Corporate Secretary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Timely delivery of a valid, later-dated proxy or a later-dated vote by telephone or on the Internet; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Voting in person at the Annual Meeting.

If you are a beneficial owner of shares held in street name, you should follow the instructions of your bank, broker or other nominee to change or revoke your voting instructions. You may also vote in person at the Annual Meeting if you obtain a legal proxy as described above.

**How can I attend a virtual annual meeting?**

The Annual Meeting will be held on Wednesday, May 13, 2026 at 10:00 a.m., Eastern Time via live webcast.

Only stockholders of record and beneficial owners of shares of Mirion common stock as of the close of business on the record date, March 16, 2026, or holders of valid proxies for such shares may participate in the Annual Meeting, including voting and asking questions during the Annual Meeting. You can attend the Annual Meeting and vote your shares in person online during the Annual Meeting via live webcast by visiting www.virtualshareholdermeeting.com/MIR2026. You will need the 16-digit control number that is printed on your proxy card to enter the Annual Meeting. If you are a beneficial owner and do not have your 16-digit control number, contact your banker, broker or other nominee. Please note that you will not be able to physically attend the Annual Meeting in person but may attend the Annual Meeting online.

 Questions and Answers

**Will I be able to ask questions at the Annual Meeting?**

We are committed to ensuring that stockholders will be afforded the same rights and opportunities to participate as they would at an in-person meeting. Our directors and members of our management team will join the Annual Meeting and be available for questions, and we are committed to answering all relevant questions we receive during the meeting. Stockholders may submit questions during the meeting through the virtual meeting platform at www.virtualshareholdermeeting.com/MIR2026 and enter the 16-digit control number found in their proxy materials. We will address questions after the voting is completed and the meeting is adjourned in order to minimize the potential impact of technical glitches on the proposals being voted upon. We will answer as many questions during the meeting as time permits, but if there are any questions that cannot be addressed due to time constraints or for any other reason, we will post answers to such questions on our website following the meeting, when permissible. If we receive substantially similar questions, we may group them together and provide a single response to avoid repetition. Only questions that are relevant to the purpose of the Annual Meeting or our business will be answered.

**What constitutes a quorum at the Annual Meeting?**

The presence, in person or by proxy, of the holders of a majority in voting power of the outstanding shares of our common stock generally entitled to vote at the Annual Meeting will constitute a quorum for the transaction of business, except that when specified business is to be voted on a class or series of securities voting as a separate class or series, the holders of a majority in voting power of the outstanding securities of such class or series shall constitute a quorum of such class or series. You will be considered part of the quorum if you return a signed and dated proxy card, if you vote by telephone or Internet, or if you attend the Annual Meeting.

Abstentions and withhold votes are counted as "shares present" at the Annual Meeting for purposes of determining whether a quorum exists. Proxies submitted by banks, brokers or other holders of record holding shares for you as a beneficial owner that do not indicate a vote for some of or all the proposals because that holder does not have voting authority and has not received voting instructions from you (so-called "broker non-votes") are also considered "shares present" for purposes of determining whether a quorum exists. If you are a beneficial owner, these holders are permitted to vote your shares on the ratification of the appointment of our independent registered public accounting firm, even if they do not receive voting instructions from you.

**What is the voting requirement to approve each of the proposals?**

Provided that there is a quorum, the voting requirements are as follows:

---

| | |
|:---|:---|
| **Proposal** | **Vote Required** |
| 1. Election of Directors | Plurality of votes present and entitled to vote on the election of directors |
| 2. Ratification of appointment of independent registered public accounting firm | Majority of votes cast |
| 3. The Say-on-Pay Proposal | Majority of votes cast |

---

A "plurality," with regard to the election of directors, means that the nominees who receive the most "For" votes cast by the holders of shares either present at the Annual Meeting or represented by proxy will be elected to our Board.

A "majority of votes cast," with regard to each of Proposals No. 2 and No. 3 means that, to be approved, a majority of the votes cast on the proposal must be voted "For" the proposal.

None of the proposals is conditioned upon the approval of any other proposal.

2026 PROXY STATEMENT 6

 Questions and Answers

**What is the impact of abstentions, withhold votes and broker non-votes?**

Abstentions, withhold votes and broker non-votes are considered "shares present" for the purpose of determining whether a quorum exists, but will not be considered votes properly cast at the Annual Meeting. Under the rules of the New York Stock Exchange (the "NYSE") without voting instructions from beneficial owners, brokers will have discretion to vote on the ratification of the appointment of the independent registered public accounting firm but not on any of the other proposals at the Annual Meeting. Therefore, in order for your voice to be heard, it is important that you vote.

**Who pays for the cost of this proxy solicitation?**

We will pay all the costs of preparing, mailing and soliciting the proxies. We will ask brokers, banks, voting trustees and other nominees and fiduciaries to forward the proxy materials to the beneficial owners of our common stock and to obtain the authority to execute proxies. We will reimburse them for their reasonable expenses upon request. In addition to mailing proxy materials, our directors, officers and employees may solicit proxies in person, by telephone or otherwise. These individuals will not be specially compensated.

**Where can I find the voting results of the Annual Meeting?**

We will announce preliminary voting results at the Annual Meeting. We also will disclose voting results on a Current Report on Form 8-K that we will file with the United States Securities and Exchange Commission (the "SEC"), within four business days after the Annual Meeting.

**Why did I receive a Notice of Internet Availability of Proxy Materials rather than a full set of proxy materials?**

In accordance with the SEC rules, we have elected to furnish our proxy materials, including this Proxy Statement and the Annual Report, primarily via the Internet rather than by mailing the materials to stockholders. The Notice of Internet Availability of Proxy Materials provides instructions on how to access our proxy materials on the Internet, how to vote, and how to request printed copies of the proxy materials. Stockholders may request to receive future proxy materials in printed form by following the instructions contained in the Notice of Internet Availability of Proxy Materials. We encourage stockholders to take advantage of the proxy materials on the Internet to reduce the costs and environmental impact of our Annual Meeting.

**How can I obtain Mirion's Annual Report on Form 10-K and other financial information?**

Stockholders can access our Annual Report on Form 10-K for the year ended December 31, 2025, and other financial information, on our website at ir.mirion.com under the caption "SEC Filings." Information on or accessible through our website is not incorporated by reference in this Proxy Statement. Alternatively, stockholders can request without charge a paper copy of the Annual Report (excluding exhibits) by writing to: Mirion Technologies, Inc., 1218 Menlo Drive, Atlanta, GA 30318, Attention: Corporate Secretary.

**I share an address with another stockholder. Why did we receive only one set of Proxy Materials?**

We may satisfy SEC rules regarding delivery of our proxy materials, including our proxy statement, or delivery of the Notice of Internet Availability of proxy materials by delivering a single copy of these documents to an address shared by two or more stockholders. This process is known as householding. To the extent we have done so, we have delivered only one set of the proxy materials or one Notice of Internet Availability of Proxy Materials, as applicable, to stockholders who share an address with another stockholder, unless contrary instructions were received prior to the mailing date. We undertake to promptly deliver, upon written or oral request, a separate copy of our proxy statement, our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 and/or our Notice of Internet Availability of Proxy Materials, as requested, to a stockholder at a shared address to which a single copy of these documents was delivered. To make such a request, please follow the instructions on our Notice of Internet Availability of Proxy Materials.

If your shares are held by a brokerage firm or bank and you prefer to receive separate copies of our proxy statement, our annual report including our Form 10-K for the fiscal year ended December 31, 2025 and/or our Notice of Internet Availability of Proxy Materials, either now or in the future, please contact your brokerage firm or bank. If your brokerage firm or bank is unable or unwilling to assist you, please contact our Investor Relations department at ir@mirion.com. Stockholders sharing an address who are receiving multiple copies of the proxy materials and/or our Notice of Internet Availability of Proxy Materials may request to receive a single copy of the proxy materials and/or our Notice of Internet Availability of Proxy Materials, either now or in the future, by contacting our Investor Relations department at ir@mirion.com.

Proposals should be sent to our Corporate Secretary at 1218 Menlo Drive, Atlanta, GA 30318. We also encourage you to submit any such proposals via email to ir@mirion.com.

**When are other proposals and stockholder nominations for the 2027 Annual Meeting due?**

With respect to proposals and nominations not to be included in our Proxy Statement pursuant to Rule 14a-8 of the Exchange Act, our Amended and Restated Bylaws (our "Bylaws") provide that stockholders who wish to nominate a director or propose other business to be brought before the stockholders at an annual meeting of stockholders must notify our Secretary by a written notice, which notice must be received at our principal executive offices not less than 120 days nor more than 150 days prior to the first anniversary date of the immediately preceding year's annual meeting of stockholders.

 Corporate Governance

![026-Mirion-Proxy_pg_18.jpg](mir-20260401_g9.jpg)

**Corporate Governance**

**Board of Directors Leadership Structure**

Our business and affairs are organized under the direction of the Board. Our Board recognizes that our success over the long term requires a robust and balanced governance framework. In addition, because our Chairman is not independent, our Board of Directors adopted Corporate Governance Guidelines that provide for a position of Lead Independent Director. Currently, Thomas D. Logan is the Chairman of our Board and our CEO and Kenneth C. Bockhorst is our Lead Independent Director.

The primary responsibilities of the Board of Directors are to provide oversight, strategic guidance, counseling and direction to management. The Board of Directors meets on a regular scheduled basis and also as required. Our Board holds separate executive session meetings for independent directors without management present at the end of regularly scheduled Board meetings.

We believe this leadership structure is best for our company and our stockholders at this time, that there is good communication between management and our non-employee directors, and that our non-employee directors are able to carry out their oversight responsibilities effectively. The relatively small size of our Board and the relationship between management and non-employee directors put each director in a position to influence agendas, flow of information, and other matters.

**Board Refreshment and Succession Planning**

Our Board has delegated to our Nominating and Corporate Governance Committee the responsibility to recommend nominees for election as directors at the annual meeting of stockholders and to fill any vacancy on our Board in accordance with its charter and our Corporate Governance Guidelines. To ensure it selects candidates who will contribute to Board effectiveness and the continued fulfillment of our purpose, our Nominating and Corporate Governance Committee actively plans for Board succession and refreshment throughout the year. In doing so, the Committee considers the Company's long-term strategy and business model, including skills and experience needed to oversee our growth priorities, capital allocation and M&A strategy, operating performance, and risk profile in highly regulated end markets. The Nominating and

2026 PROXY STATEMENT 11

------

 Corporate Governance

Corporate Governance Committee also considers the results of our annual Board self-assessment and evaluates the Board's composition and each director's skill set to determine how directors' and candidates' capabilities, skills and experiences are complementary and aligned with the long-term needs of our Board.

**Board Qualifications**

Our Nominating and Corporate Governance Committee selects individuals for nomination to our Board based on multiple criteria, with a focus on the mix of qualifications, expertise and experiences needed to oversee the Company's long-term strategy and value creation. In evaluating board composition, the Committee considers, among other things, leadership experience and judgment; finance and capital allocation; technology and cybersecurity; and sector-and market-specific experience in our end markets, including nuclear power and medical technologies, as well as experience in regulated environments and global operations, The Committee seeks directors whose skills and perspectives are complementary so that, taken together, the Board has the breadth and depth of experience to provide effective oversight of strategy, risk management, and management execution. Nominees for director must:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Possess fundamental qualities of intelligence, honesty, perceptiveness, good judgment, maturity, high ethics and standards, integrity, fairness and responsibility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have a genuine interest in Mirion and recognition that as a member of our Board, each director is accountable to all of our stockholders, not to any particular interest group.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have a background that demonstrates an understanding of business and financial affairs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have no conflict of interest or legal impediment that would interfere with the duty of loyalty owed to Mirion and our stockholders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have the ability and be willing to spend the time required to function effectively as a director.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Be compatible and able to work well with other directors and executives in a team effort with a view to a long-term relationship with Mirion as a director.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Have independent opinions and be willing to state them in a constructive manner.

Our Corporate Governance Guidelines accordingly reflect that the Nominating and Corporate Governance Committee considers an individual's qualities, performance and professional responsibilities, as well as the overall composition of the Board including, but not limited to, diversity of experience, skill set, background and other attributes, in light of the Company's long-term strategy and business model, and the challenges and needs of the Board at that time. As a majority of our Board must consist of individuals who are independent, a nominee's ability to meet the independence criteria established by the NYSE is also a factor in the nominee selection process.

For a better understanding of the qualifications of each of our directors, we encourage you to read their biographies set forth in this proxy statement.

**Director Nomination Process**

The Nominating and Corporate Governance Committee is responsible for identifying and evaluating candidates for board service and recommending nominees to the full board. Potential candidates may be identified from a variety of sources, including recommendations from current directors and senior management, as well as through the use of professional search firms and other external resources, as the Committee deems appropriate, to help broaden the pool of qualified candidates and to assist in identifying and/or assessing individuals with skills and experiences aligned with the Company's long-term strategy. The Committee will also consider candidates for director recommended by stockholders so long as the recommendations comply with the requirements of our Amended and Restated Certificate of Incorporation, our Bylaws and applicable laws, rules and regulations, including those promulgated by the SEC. When evaluating candidates the Nominating

2026 PROXY STATEMENT 12

 Corporate Governance

and Corporate Governance Committee considers the criteria described above under "Corporate Governance - Board Qualifications".

**Stockholders Recommendation and Nomination of Directors**

Stockholders wishing to recommend a candidate for nomination should submit the name of the candidate to our Corporate Secretary at our principal executive offices, together with biographical information and background material sufficient for the Nominating and Corporate Governance Committee to evaluate the recommended candidate based on its selection criteria described under "<u>[Corporate Governance — Board Qualifications](#iae13da6fe8044c5a8225aacc6fa1e8d5_43)</u>," and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date the recommendation is made. Assuming that appropriate biographical and background material has been provided on a timely basis, the Nominating and Corporate Governance Committee will apply the same criteria, and follow substantially the same process, in considering each qualifying stockholder recommendation as it does in considering other candidates.

**Profile of our Board**

Our Board is comprised of directors who bring a broad range of backgrounds, qualifications, skills, and experiences that collectively support effective oversight, strategic guidance and long-term value creation. This skills based approach and diversity of perspectives contributes to a well-rounded Board that we believe is uniquely positioned to help drive innovation, enhance our understanding of our stakeholders priorities and generally contribute to better informed and effective decision-making. Embracing differences and welcoming everyone are core values embedded in our culture and fundamental to our business and operations. We believe that a Board reflecting diverse business and professional experiences, skills, talents, expertise, educational backgrounds and other attributes strengthens overall Board effectiveness and performance, enhances dialogue, and supports long-term stockholder value and improved governance outcomes.

Our Board currently consists of eight highly qualified and actively engaged members. Except for our Chief Executive Officer, all directors meet the independence standards of the NYSE listing standards. Consistent with our Corporate Governance Guidelines, the Board regularly evaluates its composition to ensure an appropriate balance of fresh perspectives and relevant industry and subject matter expertise. Given the complexity of our business we believe effective oversight requires directors with deep knowledge of our industry, operational challenges, and strategic priorities. The breadth of our directors' experiences enables valuable insight into, and robust oversight of, our senior management team.

**Corporate Governance Framework**

We are proud of our commitment to sound corporate governance and high ethical standards, and we believe that this commitment has contributed to our success in building long-term value for our stockholders and other stakeholders by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Strengthening Board and management accountability and effectiveness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Promoting alignment with the long-term interests of our stockholders and other stakeholders; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Helping to maintain our stockholders' and other stakeholders' trust in our Company.

Our corporate governance framework includes our corporate governance documents and practices, it provides the structure that enables our Board to provide effective oversight and counsel for the Company.

**Governance Documents**

We believe that good corporate governance is important to ensure that Mirion is managed for the long-term benefit of our stockholders. Our Nominating and Corporate Governance Committee will periodically review and

Corporate Governance Framework

reassess our Corporate Governance Guidelines and overall governance structure. Complete copies of our current Board committee charters and our Corporate Governance Guidelines and our Code of Business Conduct and Ethics are available on our investor relations website, at ir.mirion.com/corporate-governance/governance-documents. We will post any amendments on the same website. Information on, or accessible through, our website is not incorporated by reference in this Proxy Statement.

**Code of Ethics and Business Conduct**

We have adopted a Code of Ethics and Business Conduct that applies to all of our employees, officers, and directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. We also maintain separate versions of our Code of Ethics and Business Conduct that apply to our channel partners and suppliers. The full text of our Company Code of Ethics and Business Conduct is available on the investor relations page on our website at ir.mirion.com/corporate-governance/governance-documents. The supplier version of our Code of Conduct is available on the legal page of our website at mirion.com/legal. We will post any amendments to the different versions of our Code of Ethics and Business Conduct at the same website locations. Information on, or accessible through, our website is not incorporated by reference in this Proxy Statement.

**Prohibition on Hedging and Stock Pledging**

Hedging or monetization transactions can be accomplished through a number of possible mechanisms, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. Hedging transactions may permit a director, officer or employee to continue to own our securities obtained through employee benefit plans or otherwise, but without the full risks and rewards of ownership. When that occurs, the director, officer or employee may no longer have the same objectives as our other stockholders. Therefore, directors, officers and employees are prohibited by our Insider Trading Policy from engaging in any such transactions.

In addition, pledged securities may be sold by the pledgee without the pledgor's consent under certain conditions. For example, securities held in a margin account may be sold by a broker without the customer's consent if the customer fails to meet a margin call. Because such a sale may occur at a time when an employee or a director has material inside information or is otherwise not permitted to trade in Company securities, the Company prohibits employees, officers and directors from pledging Company securities in any circumstance, including by purchasing Company securities on margin or holding Company securities in a margin account. As of the record date, there are no outstanding pledges by any Company officers or directors.

**Stockholder Communication and Outreach**

We value the views of our stockholders and believe that building positive relationships with our stockholders is critical to our long-term success. It allows us to convey our strategy for long-term value creation and sustainable financial performance. It also helps us to understand what is top-of-mind for our stockholders. We engage with stockholders through phone calls, attendance at investor conferences, presentations, and individual meetings both in-person or virtual. Following our December 2024 Investor Day, held at the New York Stock Exchange, we experienced increased investor interest throughout 2025. Our management team met with representatives from many of our top institutional shareholders and engaged with stockholders on topics as varied as our business strategy, financial performance, market tailwinds from nuclear power and cancer care, investment in research and development, executive compensation, governance and sustainability matters. We routinely report to the Board on the substance and nature of these stockholder discussions.

We also provide additional avenues for our stockholders and other investor constituencies to communicate with us. Written communications may be submitted to ir@mirion.com, or by writing to Mirion Technologies, Inc., 1218 Menlo Drive, Atlanta, GA 30318 Attention: Investor Relations.

Corporate Governance Framework

**Corporate Responsibility**

Our culture and core values are central to how we operate and grow as a company. As part of our culture, we recognize the importance of corporate responsibility to our employees, customers and stockholders. With the support and oversight of our Board, we seek to manage material sustainability-related risks and opportunities and to operate a business model that is positioned to create long-term value in our highly regulated nuclear and medical end markets.

Our Nominating and Corporate Governance Committee, working together with our Compensation and Audit Committees, is responsible for overseeing the Company's governance matters. Internally, members of our senior leadership team provide tactical day-to-day management, with sponsorship and oversight from our Chief Financial Officer. Additional subject matter experts from areas such as investor relations, finance, government affairs, R&D, product management, legal and compliance are engaged on a regular basis to provide their insight and expertise to relevant topic areas.

*Corporate Sustainability* 

Our mission is to harness our unrivaled knowledge of ionizing radiation for the greater good of humanity. Mirion is committed to being a responsible steward of the environment and to managing environmental risks and opportunities relevant to our operations and the markets we serve. We understand that environmental management is important to our stakeholders (employees, customers, stockholders) and we care about the environmental impact we have on the communities in which we operate. In addition, we recognize the importance of the management of natural resources. Protection of the natural environment is part of our goal to conduct our business in a safe and responsible manner, and we strive to improve our own environmental performance through the carefully managed use of natural resources and compliance with all applicable environmental laws and regulations. Our engineers are helping to modernize nuclear power for a cleaner world by transitioning legacy systems to digital platforms and laying the groundwork for artificial intelligence and predictive intelligence to help elevate nuclear plant safety and reliability.

Underlying our mission is our core belief that nuclear technologies will play a critical role in the transition to meeting rising electricity demand and providing innovative healthcare solutions. Our Nuclear & Safety products and services protect people, property and the environment from the potentially harmful effects of ionizing radiation, specifically when utilized in electric energy production. Our Medical products, including software, and services find applications in nuclear medicine, radiation therapy and imaging diagnostics. They support and enhance life-saving medical procedures for patients and protect the healthcare providers who administer them.

Looking inward, we are committed to creating positive change through sustainable and responsible operations. All Company sites strive for safety, quality, delivery, and cost targets from the organizational level to the product level. Four of our largest production sites maintain ISO 14001 Environmental Management Systems. Environmental impact is currently monitored at the facility level, and we are planning to start monitoring and collecting energy consumption data at each of our facilities to identify areas of improvement and implement energy-saving initiatives.

*Human Capital, Supply Chain and Human Rights*

We are committed to our employees and aim to be an employer of choice in all industries in which we operate. We seek to attract, engage, develop and retain talented employees who are aligned with and passionate about our mission and our values (Integrity, Commitment, Accountability, Respect and Exploration).

We seek to continuously improve our inclusive and ethical culture by supporting a diversity of backgrounds, experiences and perspectives in our workforce and promoting an engaging workplace that encourages participation and inclusion of all employees. We organize regular employee engagement surveys to collect feedback, better understand and improve employees' experiences and identify opportunities to strengthen our culture.

2026 PROXY STATEMENT 24

Corporate Governance Framework

We are always looking inward to ensure a supportive environment for all of our employees and provide locally competitive compensation and benefits and promote growth and development opportunities. Our compensation programs, practices and policies reflect our commitment to reward short- and long-term performance. The professional development of our employees is critical to our Company success and we provide employees with a wide range of development opportunities, including but not limited to a Mentorship Program, product and sales training, as well as compliance training including on the topics of cybersecurity, artificial intelligence, and workplace safety. We have a well established Volunteer Time Off Program globally as well as a Parental Leave Policy for U.S. employees, and we also publish global mental health resources for all employees.

As a company that manufactures devices to keep others safe, we place great focus on the safety of our own employees. Safety is a key consideration in our manufacturing processes. All facilities are expected to comply with local safety laws and regulations and maintain comprehensive safety programs, including corrective action processes and emergency response plans. Employees undergo regular health and safety training to ensure compliance with, and communication of, safety policies and procedures.

We are committed to respecting, protecting, and promoting human rights and freedoms within our own operations and supply chain. We maintain a Human Rights Policy that outlines our human rights expectations for our operations worldwide. All employees, agents and other Company representatives are expected to comply with all human rights standards, laws and regulations of every country in which Mirion operates. Our policy statement further defines our expectations around prohibition of harassment, freedom of association, health and safety, and freedom of engagement.

We launched a Supplier Code of Conduct to flow through to our vendors our expectation that they operate in a socially and environmentally friendly manner, in compliance with our own Code of Ethics and Business Conduct and Human Rights Policy. Our Supplier Code of Conduct was built upon our pre-existing Statement on Modern Slavery and Human Trafficking targeting slavery, forced labor, child labor and other forms of human trafficking and human rights violations. It added prohibitions against unfair wages or unsafe working conditions and other unethical business practices, including with regard to the environment, and offers a channel for supplier workers or other interested parties to report concerns or violations directly to us.

*Corporate Governance and Ethics*

We are committed to sound and ethical governance practices that benefit all of our constituencies, including our stockholders, employees, customers and other business partners. Our Board has adopted Corporate Governance Guidelines that provide an effective framework for Board oversight. Our Nominating and Corporate Governance Committee regularly assesses the corporate governance regulatory landscape, including policy developments of proxy advisory firms, to identify emerging best practices that could benefit our Company if implemented, thereby enhancing the creation of long term stockholder value.

As a result of such work, the Nominating and Corporate Governance Committee has recommended, and the Board has approved, the following corporate governance and ethics related improvements since the Company became public:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adopting a Stock Ownership Policy (See "<u>[Other Compensation Governance Practices - Stock Ownership Policy](#iae13da6fe8044c5a8225aacc6fa1e8d5_184)</u>");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adopting a Clawback policy (See "<u>[Other Compensation Governance Practices - Clawback Policy](#iae13da6fe8044c5a8225aacc6fa1e8d5_184)</u>")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Appointing a Lead Independent Director;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Adopting and publishing a Supplier Code of Conduct to flow through to our vendors the tenets of our Company Code of Ethics and Business Conduct and augment our prior Statement on Modern Slavery and Human Trafficking;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amending the Charter of the Nominating and Corporate Governance Committee to give such committee oversight of Corporate Sustainability matters (See "<u>[Board Oversight of Corporate Sustainability Matters](#iae13da6fe8044c5a8225aacc6fa1e8d5_106)</u>"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amending the Charter of the Audit Committee to give such committee oversight of cybersecurity risk (See "<u>[Board Oversight of Cybersecurity Risk Management](#iae13da6fe8044c5a8225aacc6fa1e8d5_109)</u>").

Specifically, in addition to the above Governance developments disclosed in our last proxy statement, in 2025 our Nominating and Corporate Governance Committee has recommended, and the Board has approved, the following corporate governance and ethics related improvements to enhance our commitment to sound governance practices:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amending the Charter of the Audit Committee to give such committee oversight of the enterprise risk management ("ERM") framework and governance process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amending the Corporate Governance Guidelines to address policy developments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amended the Nominating & Corporate Governance Committee charter to address policy developments and give the committee oversight over government affairs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amended the Compensation Committee charter to memorialize the committee's responsibilities to include review of Say-on-Pay voting and oversight of policies and strategies related to talent, human capital management, employee engagement, retention and culture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amended the Code of Ethics and Business Conduct to add sections on artificial intelligence, cybersecurity and ethics ambassadors and updated sections on political contributions, discrimination and harassment and conflicts of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amending the Corporation's Insider Trading Policy to update list of preapproved transactions and require audit committee and board approval for amendments to the policy; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Amending the Public Disclosure Policy to clarify material non public information and require audit committee and board approval for amendments to the policy.

**Role of Board in Risk Oversight**

The Board provides oversight of the Company's ERM framework and processes management uses to identify, monitor, and manage business and material risks. Management is responsible for the day-to-day risk management and for maintaining an ERM program that includes (i) risk identification and assessment, (ii) assignment of ownership and accountability, (iii) mitigation planning and execution, and (iv) escalation and reporting to the Board and its committees. The Board and its committees receive regular updates regarding the Company's principal risks and related mitigation activities.

The Audit Committee assists the Board in the overseeing risk management, including the integrity of financial reporting, compliance, legal and regulatory matters, internal controls , and the governance of the ERM program. Through its regular meetings with management, including the finance, legal and compliance, internal audit, ERM and information technology functions, the Audit Committee reviews and discusses all significant areas of our business and summarizes for our Board all areas of risk and the appropriate mitigating factors. In addition, our Board receives periodic detailed operating performance reviews from management. In connection with these responsibilities, in addition to receiving relevant management reporting, the independent directors have regular opportunities to meet in executive session without management present. The Board and its committees may also engage independent outside advisors, as appropriate, to provide additional expertise and support effective oversight. The Board's risk oversight approach is integrated with its oversight of strategy. As the Company's strategy evolves and as the external environment shifts, the Board expects management to reassess the Company's risk profile, update mitigation plans and controls, and refine the cadence and content of reporting to ensure the Board continues to receive timely, decision-useful information.

**Lead Independent Director**

Our independent directors have appointed Kenneth Bockhorst as Lead Independent Director. The Lead Independent Director position includes the following responsibilities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lead the executive sessions of the independent directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Serve as a liaison between the Chairman of the Board and CEO, and the independent directors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Review and approve the agendas for the regular meetings of the Board, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Preside at all meetings of the Board where the Chair is absent.

The Lead Director may be removed or replaced at any time with or without cause by a majority vote of the independent directors then in office.

Interested parties who wish to contact the Lead Independent Director may write to: Lead Independent Director of the Mirion Technologies Board of Directors, Mirion Technologies, Inc., 1218 Menlo Drive, Atlanta, GA 30318 Attention: Corporate Secretary. The Corporate Secretary will promptly relay to the Lead Independent Director all communications that she determines require prompt attention and will regularly provide our Board with a summary of all substantive communications.

**Director Independence**

NYSE rules generally require that independent directors must comprise a majority of a listed company's board of directors. Our Board has undertaken a review of the independence of each director. Based on information provided by each director concerning their background, employment and affiliations, our Board has determined that Kenneth C. Bockhorst, Robert A. Cascella, Steven W. Etzel, Lawrence D. Kingsley, John W. Kuo, Jody A. Markopoulos and Sheila Rege, representing seven (7) of our eight (8) directors, are "independent" as that term is defined under the applicable rules and regulations of the SEC and the listing requirements and rules of the NYSE. In making this determination, our Board considered the current and prior relationships that each non-employee director has with Mirion and all other facts and circumstances that our Board deemed relevant in determining their independence, including the beneficial ownership of our common stock by each non-employee director and the transactions involving them described under "<u>[Certain Relationships and Related Party Transactions](#iae13da6fe8044c5a8225aacc6fa1e8d5_229)</u>." Our independent directors hold executive session meetings at which only independent directors are present at each regularly scheduled meeting of the Board.

**Related Party Transaction Policy**

Our Audit Committee has the primary responsibility for reviewing and approving or ratifying transactions with related parties. Our Audit Committee has adopted a formal Related Party Transaction Policy, pursuant to which the Audit Committee reviews all transactions which in which the Company or any of its subsidiaries, was, is, or will be a participant, the amount of which exceeds $120,000 and in which any related party had, has or will have a direct or indirect material interest. The Audit Committee must approve or ratify any covered related party transaction for it to be consummated or continue.

The Audit Committee reviews these related party transactions as they arise and are reported to the Audit Committee. The Audit Committee also reviews materials prepared by our Board and our executive officers to determine whether any related party transactions have occurred that have not been reported. In reviewing any related party transaction, the Audit Committee is to consider all relevant facts and circumstances, including the aggregate dollar value of the transaction, the related party's relationship to us and interest in the transaction, and the benefits to us of the transaction. The Audit Committee determines, in its discretion, whether the proposed transaction is in the best interests of Mirion and our stockholders.

**Compensation Committee Interlocks and Insider Participation**

Robert A. Cascella, Steven W. Etzel, Lawrence D. Kingsley, John W. Kuo and Sheila Rege served as members of the Compensation Committee during 2025. None of such persons is or was formerly an officer or an employee of Mirion. None of our executive officers currently serves, or has served during the last year, as a member of the Board of Directors or Compensation Committee of any entity that has one or more executive officers serving as a member of our Board.

**Delinquent Section 16(a) Reports** 

Section 16(a) of the Exchange Act requires the Company's directors and executive officers, and persons who own more than 10% of the Company's common stock, to file with the SEC certain reports of beneficial ownership of the Company's common stock. Based solely on a review of information furnished to us, the Company believes that its directors, officers and more than 10% shareholders complied with all applicable Section 16(a) filing requirements during the year ended December 31, 2025, except for an inadvertent late Form 4 filing for Mr. Bockhorst disclosing shares donated to a charitable organization.

**Board Leadership Structure**

The Board believes one of its most important responsibilities is to determine the appropriate leadership structure for the Board at a given time that best enables it to provide effective, independent oversight of management and support long-term value creation for the Company and our stakeholders.

Accordingly, the Board does not have a predetermined policy as to whether or not the roles of the Board Chair and CEO should be combined or separate. Instead, the Board takes a flexible approach, enabling it to adapt its leadership structure to best meet the needs of the Board, the Company and its stockholders and other stakeholders as characteristics and circumstances change.

Each year the Board reviews the Board's leadership structure, including whether the roles of Board Chair and CEO should be combined or separate and what leadership structure is appropriate given the specific characteristics and circumstances of the Company at that time.

In 2024, the Nominating and Corporate Governance Committee, as part of conducting its annual assessment, determined that combining the roles of Board Chair and CEO is best to serve the current needs of the Board, the Company, our stockholders and other stakeholders and will continue to effectively allocate responsibility and oversight between management and the Board. The Board elected Mr. Logan as Chairman of the Board in February 2025.

**Annual Board Assessment**

Our Board believes that a rigorous annual review of its performance is essential to ensuring its effectiveness.

To that end, each year, the Nominating and Corporate Governance Committee determines the format and approach for, and conducts, an annual Board self-assessment. This self-assessment involves evaluating the performance of the Board, its Committees, the Chairman of the Board, the Committee chairs and each director and helps identify ways to enhance their effectiveness.

2026 PROXY STATEMENT 31

------

Corporate Governance Framework

The annual self-assessment process uses questionnaires with each director to solicit candid feedback and gather suggestions for improvement. The process also provides opportunities for each director to reflect on their own performance, as well as the performance of the other directors. Results from the annual self-assessment are presented to the Board for discussion and action.

**Board Oversight of Company Strategy**

Management annually presents the Company's long-term business and financial strategic plan to the Board for review, discussion and approval. The plan identifies and assesses the strengths, weaknesses, opportunities and threats to the continuing creation of enduring growth and long-term stakeholder value, and management's presentation to the Board includes overviews of the business and market trends, historical financial performance, assessments of opportunities for long-term growth and margin expansion and projected long-term financial performance. The Board acts as a strategic partner in this process, offering insight and additional perspectives and challenging management's plan as it deems appropriate.

In addition to this annual corporate strategy review, the Board is involved in strategy planning and risk oversight throughout the year:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Management regularly presents information to the Board regarding the Company's various business segments, their markets and strategic priorities, as well as trends expected to pose significant risks or strategic opportunities for the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board annually reviews and approves our key financial and other objectives and budget.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Management regularly presents its capital allocation and deployment plans to the management Finance Committee and the Board for review and discussion, and the Board (or the appropriate Committee) approves specific significant actions and transactions, to ensure that we deploy our capital to create long-term value for our stockholders and other stakeholders, including through capital and operating expenditures or strategic acquisitions that support future innovation or growth, as well as share repurchases that return cash to our stockholders.

**Board Oversight of Corporate Responsibility Matters**

The Board has overall oversight of Corporate Responsibility Matters. The Board has delegated risk oversight of policies and operational controls of environmental, social and corporate governance matters, including resources management and human capital management to the Nominating and Corporate Governance Committee, working in coordination with the Audit Committee and the Compensation Committee.

Corporate Governance Framework

**Board Oversight of Cybersecurity Risk Management**

The Board has overall oversight responsibility for our risk management, and delegates its oversight of risk assessment and management guidelines to the Audit Committee. The Audit Committee reviews and makes recommendations to management or the Board on matters relating to cybersecurity. Management provides quarterly updates to the Audit Committee and an annual update to the Board. These discussions may include updates on threat focus, roadmaps covering planned improvements, status updates on key improvements efforts, overview information on any recent incidents or significant vulnerabilities (if any), and the status of key information security initiatives.

Our Cybersecurity program is led by our Chief Information Officer and Chief Information Security Officer who provide the updates to the Audit Committee and the Board. In addition, the Chair of the Audit Committee, Steven Etzel, and one member of the Audit Committee, Sheila Rege, and the chair of the Nominating and Corporate Governance Committee, John Kuo, have all earned the CERT Certificate in Cyber-Risk Oversight Program from the National Association of Corporate Directors, demonstrating an advanced understanding of the role of the Board in cybersecurity oversight.

**Communications with Directors**

Interested parties may communicate with our Board, our Lead Independent Director, or with any individual director by writing to our Board or to the particular director and mailing the correspondence to: Mirion Technologies, Inc., 1218 Menlo Drive, Atlanta, GA 30318, Attention: Corporate Secretary. The Corporate Secretary will promptly relay to the addressee all communications that she determines require prompt attention and will regularly provide our Board with a summary of all substantive communications.

Director Compensation

**Director Compensation**

Pursuant to our director compensation program (the "Director Compensation Program"), non-employee directors are eligible to receive the following cash compensation, paid quarterly in arrears, for their service as members of the Board and certain sub-committees thereof:

---

| | |
|:---|:---|
| **Position** | **Annual Cash Retainer** |
| Board Service | $76500 |
| plus (as applicable): |  |
| Lead Independent Director | $30000 |
| Audit Committee Chair | $20000 |
| Compensation Committee Chair | $15000 |
| Nominating/Governance Committee Chair | $12500 |

---

The foregoing cash retainer fees are pro-rated for partial quarters of Board service. In lieu of cash, non-employee directors may elect to receive full payment of their retainers in shares of our Class A common stock on a quarterly basis, issued quarterly in arrears on the last day of each calendar quarter. The number of shares of our Class A common stock issuable pursuant to any such election is determined by dividing the quarterly cash retainer fee by the fair market value of our common stock on the trading day immediately prior to the date the cash retainer would otherwise be paid. Payment of retainers in a combination of cash and stock is not permitted.

In addition, non-employee directors receive grants of equity awards under our 2021 Omnibus Incentive Plan (the "Incentive Plan"). Each year, the Board or Compensation Committee provides each non-employee director who will continue to serve on the Board with a grant of restricted stock units ("RSUs") with an approximate grant date fair market value of $140,000. Such grants are ordinarily approved at the time of the annual stockholder meeting. These annual equity awards vest quarterly, and will be fully vested on the earlier to occur of (i) the first anniversary of the grant date and (ii) the date of the annual stockholder meeting following the grant date, subject to the non-employee director's continued service on the Board through each such vesting date. A non-employee director who is elected or appointed to the Board at any time other than at the annual stockholder meeting will, at the time of such election or appointment, receive an award of RSUs with a grant date fair market value equal to the product of $140,000 multiplied by a fraction (i) the numerator of which is equal to the number of days between the date of the director's initial election or appointment to the Board and the date which is the first anniversary of the date of the most recent annual stockholder meeting occurring before the new non-employee director is elected or appointed to the Board, and (ii) the denominator of which is 365. Such awards also vest quarterly and ordinarily will be fully vested on the earlier to occur of (i) the first anniversary of the date of the most recent annual stockholder meeting and (ii) the date of the annual stockholder meeting following the grant date, subject to the non-employee director's continued service on the Board through each such vesting date.

The Director Compensation Program also provides that the Company will reimburse non-employee directors for their ordinary, necessary and reasonable out-of-pocket travel expenses to cover in-person attendance at, and participation in, Board meetings, in accordance with the Company's applicable expense reimbursement policies and procedures as in effect from time to time. We also reimburse non-employee directors up to $10,000 each fiscal year for fees and expenses associated with qualified director education programs in accordance with our Director Continuing Education Policy Statement.

Proposal No. 2 - Ratification of Appointment of Independent Registered Public Accounting Firm

**Audit Fees**. Audit fees consist of fees billed or expected to be billed for professional services rendered for the audit of our year-end financial statements and services that are normally provided by Deloitte in connection with statutory and regulatory filings. The above amounts include interim procedures and audit fees, as well as attendance at Audit Committee meetings.

Audit-Related Fees. Audit-related services consist of fees billed for assurance and related services that are reasonably related to performance of the audit or review of our financial statements and are not reported under "Audit Fees." These services include attest services that are not required by statute or regulation and consultations concerning financial accounting and reporting standards.

Tax Fees. Tax fees consist of fees billed for tax planning and tax advisory services.

The Audit Committee of our Board of Directors has appointed Deloitte as our independent registered public accounting firm since the consummation of the Business Combination in 2021. Deloitte has served as our auditors prior to the Business Combination since 2015.

We are asking our stockholders to ratify the selection of Deloitte as our independent registered public accounting firm. Although ratification is not required by our Bylaws or otherwise, we are submitting the selection of Deloitte to our stockholders for ratification as a matter of good corporate practice and because we value our stockholders' views on our independent registered public accounting firm. In the event that our stockholders fail to ratify the selection, the Audit Committee will review its future selection of independent auditors. Even if our stockholders ratify the selection, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the Audit Committee believes that such a change would be in the best interest of Mirion and our stockholders.

Representatives of Deloitte are expected to attend the Annual Meeting, will have an opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate questions.

**Pre-Approval Policy**

Our Audit Committee was formed upon the consummation of our Business Combination. As a result, the Audit Committee did not pre-approve all of the foregoing services, although any services rendered prior to the formation of our Audit Committee were approved by our Board of Directors. Since the formation of our Audit Committee, and on a going-forward basis, the Audit Committee has and will pre-approve all auditing services and permitted non-audit services to be performed for us by our auditors, including the fees and terms thereof (subject to the de minimis exceptions for non-audit services described in the Exchange Act which are approved by the Audit Committee prior to the completion of the audit).

**VOTE REQUIRED**

The affirmative vote of the holders of a majority of the votes cast at the meeting on this proposal, with shares of our Class A common stock and Class B common stock voting together as a single class, shall be required to approve this proposal. Abstentions and broker non-votes, if any, will have no effect on the outcome of the vote on this Proposal.

**The Board recommends a vote "FOR" the ratification of the appointment of Deloitte & Touche, LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026.**

Audit Committee Report

**Audit Committee Report**

With respect to Mirion's financial reporting process, the management of Mirion is responsible for establishing and maintaining internal controls and preparing Mirion's consolidated financial statements. Mirion's independent registered public accounting firm, Deloitte & Touche, LLP ("Deloitte"), is responsible for auditing these financial statements. It is the responsibility of the Audit Committee to oversee these activities. The Audit Committee does not itself prepare financial statements or perform audits, and its members are not auditors or certifiers of Mirion's financial statements. We have relied, without independent verification, on management's representation that the financial statements have been prepared with integrity and objectivity and in conformity with US GAAP and on the representations of Deloitte included in its audit of Mirion's consolidated financial statements.

We have reviewed and discussed the audited consolidated financial statements for the fiscal year ended December 31, 2025 with Mirion's management and with Deloitte, including the results of the independent registered public accounting firm's audit of Mirion's financial statements. We have also discussed with Deloitte all matters required to be discussed by the Standards of the Public Company Accounting Oversight Board ("PCAOB") for communication with Audit Committees, under which Deloitte must provide us with additional information regarding the scope and results of its audit of Mirion's consolidated financial statements.

We have also received and reviewed the written disclosures and the letter from Deloitte required by applicable requirements of the PCAOB regarding Deloitte's communications with the Audit Committee concerning independence, and have discussed with Deloitte its independence from Mirion, as well as any relationships that may impact Deloitte's objectivity and independence, including whether the provision of non-audit services by Deloitte during fiscal year 2025 was compatible with the auditor's independence.

Based on our review of the matters noted above and our discussions with Mirion's management and independent registered public accountants, we recommended to the Board of Directors that the audited consolidated financial statements be included in Mirion's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, for filing with the Securities and Exchange Commission.

**Our Executive Compensation Program**

Our executive compensation program is designed to attract, motivate and retain high quality executives needed to fulfill our mission. Our goal is to support business priorities deemed essential by our Board, as well as satisfy the accepted governance standards of impartial external stakeholders. In furtherance of our compensation philosophy and objectives, our program framework includes a mix of three key compensation elements: (i) base salary, (ii) short-term cash incentive awards, and (iii) long-term equity incentive awards, the value of which, for each NEO, is within a competitive range for a similar position of our peer group and market survey compensation data (as described more fully below). We have not adopted any formal policies or guidelines for allocating compensation between fixed and variable compensation, cash and equity incentive awards, or short-term and long-term compensation. Our mix of compensation elements is designed to reward recent results and motivate long-term performance consistent with our philosophy through a combination of short-term cash and long-term equity incentive awards. To incentivize long term performance and align the interests of our NEOs

Executive Compensation Summary

with stockholders, our compensation elements include a significant performance-based component, with variable, at-risk pay constituting a meaningful portion of overall compensation (in 2025, 88% for our CEO and approximately 71% for our other NEOs), as illustrated below.

**Target Total Direct Compensation Summary**

The target total direct compensation for each of our NEOs reflects their substantial contributions to our exceptional performance. The Compensation Committee determined 2025 compensation for our NEOs considering financial and non-financial goals geared toward sustaining our long-term growth and delivering stockholder value, resulting in Revenue of $925.4 million in 2025 (7.5% higher than 2024), net income of $29.8 million (compared to a net loss of ($36.6) million in 2024) and Adjusted EBITDA of $227.9 million (11.9% higher than 2024).<sup>(1)</sup> In making these determinations, the Compensation Committee gives primary consideration to each NEO's impact on our results in the context of our business model and their scope of responsibility, in addition to other relevant factors (such as prior experience and sustained high performance) and data on prevailing market compensation levels.

The following table provides an overview of target total direct compensation for our NEOs for fiscal year 2025, including a breakdown of each of the three key elements.

Compensation Philosophy and Practices

![026-Mirion-Proxy_pg_54.jpg](mir-20260401_g31.jpg)

**Compensation Philosophy and Practices**

**Compensation Philosophy and Objectives** 

We have developed our total compensation package for executives based on our overarching philosophy of paying for demonstrable performance that is needed to fulfill our mission. Our goal is to attract, motivate and retain high quality executives to support the business priorities deemed essential by our Board, as well as to align the interests of our executives with those of our impartial external stakeholders. Consistent with our philosophy, we have designed compensation packages that are (i) competitive with market practice, (ii) reward both organizational and individual performance by providing a significant portion of our NEOs' cash compensation in the form of "at-risk" incentive compensation tied to key performance goals, and (iii) closely align the interests of our NEOs with those of our stockholders by providing the majority of our NEOs' compensation in equity (a 80% blended rate across all NEOs), including performance-based equity.

Our executive compensation program framework includes a mix of three key compensation elements: (i) base salary, (ii) short-term cash incentive awards, and (iii) long-term equity incentive awards. In determining the amount of each compensation element awarded to our NEOs, our Compensation Committee or Board, as applicable, looks at each NEO's overall compensation package, as well as the amount of each compensation element for the NEO relative to both internal and external pay to determine whether such amounts and the overall mix of elements for the NEO's role further the principles and objectives of our executive compensation program.

The Compensation Committee also annually reviews and analyzes market trends and adjusts the design and operation of our executive compensation program from time to time as it deems necessary and appropriate. In structuring and adjusting the executive compensation program, the Compensation Committee places no formal weighting on any one factor. As we continue to mature as a public company, the Compensation Committee will continue to review and evaluate our executive compensation program to ensure it aligns with our compensation philosophy and objectives.

Compensation Philosophy and Practices

**Executive Compensation Best Practices**

In executing our compensation program and determining executive compensation, we are guided by the following corporate governance best practices designed to protect the interests of our stockholders.

| | |
|:---|:---|
| **What We Do** | **What We Don't Do** |
| ☒ ***Pay-for-Performance Philosophy.*** We align pay and performance by awarding a substantial portion of the compensation paid to our executives in the form of variable, "at-risk" performance-based compensation linked to the achievement of rigorous performance goals.<br>☒ ***Balanced Short-Term and Long-Term Compensation.*** We grant compensation that discourages short-term risk taking at the expense of long-term results.<br>☒ ***Maintain an Independent Compensation Committee and Independent Compensation Committee Advisor.*** Our Compensation Committee is comprised solely of independent directors and engages its own independent consultant.<br>☒ ***Stock Ownership Policy.*** All NEOs are subject to significant stock ownership requirements. Refer to the Stock Ownership Policy section under **Other Compensation Governance Practices.**<br>☒ ***Clawback.*** The Board requires reimbursement to the Company of any performance-based award in the event of certain accounting restatements due to the material noncompliance of the Company with any financial reporting requirement under the securities laws. Our clawback policy is described in more detail under "Other Compensation Governance Practices Clawback Policy" below. | ☒ ***No Excise Tax "Gross-Ups".*** We do not provide any "gross-ups" for excise taxes that our employees might owe as a result of the application of Sections 280G or 4999 of the Internal Revenue Code.<br>☒ ***No "Single-Trigger" Change in Control Arrangements.*** We do not provide for "single-trigger" acceleration of compensation or benefits solely upon a change in control.<br>☒ ***No Excessive Perks.*** We do not provide any excessive perquisites to our NEOs.<br>☒ ***Do Not Permit Hedging or Pledging.*** We prohibit directors and employees, including our NEOs, from hedging and pledging our securities. |

**Executive Compensation Process**

*Role of the Compensation Committee and Management*

The Company's executive compensation program has been administered by our Compensation Committee, which is comprised entirely of independent directors. Our Compensation Committee is responsible for establishing, implementing, monitoring and evaluating our executive compensation program. The Compensation Committee reviews and approves the compensation of our NEOs, other than the compensation of our CEO, for which the Compensation Committee makes recommendations to our Board for the Board's approval. The Compensation Committee's responsibilities and authority are described fully in the Compensation Committee's charter, which is available on our website at ir.mirion.com (under the tab "Governance—Governance Documents"). Information on or accessible through our website is not incorporated by reference in this Proxy Statement. Other than the delegation of authority to the CEO to grant a limited number of equity awards to non-executive officer employees, the Compensation Committee has not delegated any of its authorities to other persons or committees.

The Compensation Committee also consults with members of our management team, including our CEO when making compensation decisions. While the Compensation Committee considers our CEO's recommendations, the Compensation Committee ultimately uses its own business judgment and experience in approving, or making recommendations to the Board where applicable, regarding individual compensation elements and the amount of each element for our NEOs. Our CEO is recused from all determinations regarding his own compensation.

2026 PROXY STATEMENT 51

------

Compensation Philosophy and Practices

The compensation of our NEOs is reviewed at least annually by our Compensation Committee. Our Compensation Committee evaluates and determines any recommended compensation adjustments or awards to our NEOs or, if applicable, make recommendations to the Board for final determination.

*Role of Compensation Consultant*

From 2021 through April 2025, the Compensation Committee had engaged WTW to be its compensation consultant and it assisted on matters relating to our executive compensation program pursuant to its authority under the Compensation Committee charter. A representative of WTW attended meetings of the Compensation Committee as requested. WTW reported directly to the Compensation Committee. In April 2025, the Compensation Committee engaged Compensia as its independent compensation consultant to assist the Compensation Committee in its annual review of the Company's executive compensation practices for continuing appropriateness and reasonableness and to make recommendations regarding executive office compensation levels and structures. Similar to WTW, a representative of Compensia attends meetings to the Compensation Committee as requested and Compensia reports directly to the Compensation Committee.

The Compensation Committee has evaluated both WTW and Compensia's independence by considering the six factors set forth in Rule 10C-1(b)(4)(i) through the (vi) of the Exchange Act. After review of information provided by each of the members of the Compensation Committee as well as information provided by each of WTW and Compensia, the Compensation Committee determined that there were no conflicts of interest raised by the work of either WTW or Compensia with the Compensation Committee. The Compensation Committee is directly responsible for the appointment, compensation and oversight of the work of any such advisor and has sole authority to approve all such advisors' fees and other retention terms. WTW was paid aggregate fees of approximately $45,173 in 2025 for advice to the Compensation Committee with respect to executive officer and director compensation. WTW separately provided insurance risk and brokering services to the Company in 2025, and was paid aggregate fees for that work of approximately $763,253, inclusive of $469,500 in M&A related Representations and Warranties Insurance. The Compensation Committee does not consider that separate insurance-related work, and fees, to present a conflict with respect to WTW's role in advising on executive officer and director compensation. The decision to engage WTW for the insurance risk and brokering services was made by members of Mirion management and did not require approval of the Board or the Compensation Committee.

Compensia has no other business relationship with the Company and receives no payments from the Company other than fees for services to the Compensation Committee.

*Peer Group* 

The Compensation Committee, with the assistance of WTW, developed and approved the following compensation peer group in August 2024 for setting 2025 CEO and CFO compensation. In developing the peer group, the Compensation Committee considered a variety of factors, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Primary and related industries: The peer group reflects companies operating in electronic equipment, machinery and heath care equipment industries reflective of our technologies and medical business segments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Company size: The peer group reflects companies approximately 0.25x smaller than and up to approximately 4x larger than us, based on revenue. The Compensation Committee also reviews market capitalization and employee count as secondary reference points.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Geography: The peer group only reflects companies headquartered in the U.S.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ownership Structure: The peer group only reflects stand-alone corporate entities.

The Compensation Committee reviews our compensation peer group at least annually and makes adjustments to its composition as necessary or appropriate, taking into account changes in both our business and the businesses of the companies in the compensation peer group.

In evaluating the pay competitiveness of 2025 NEO compensation, the Compensation Committee also considered general industry data from WTW's 2024 General Industry Executive Survey as well as peer proxy data for the CEO and CFO. Market data is only one element that the Compensation Committee uses to make pay decisions; multiple factors are considered in determining the target total compensation opportunity, in addition to market data, including our compensation philosophy, the executive's role and responsibility, the executive's past performance, internal equity, the executive's expected contributions and the executive's experience in the role.

**Say-on-Pay and Stockholder Engagement** 

In setting NEO compensation, we pay careful attention to any feedback we receive from our stockholders about our executive compensation program, including, the results of stockholder advisory votes on say-on-pay proposals presented at our annual meetings of stockholders. Although the results of the say-on-pay vote are advisory and not binding on the Company, the Board and the Compensation Committee considers this vote outcome when making compensation decisions for our NEOs.

At the 2025 annual meeting of stockholders, approximately 94% of votes cast (excluding abstentions and broker non-votes) were cast in favor of the compensation of our NEOs. Given the strong support reflected by the results of the 2025 say-on-pay proposal, the Compensation Committee maintained our general philosophy on executive compensation for 2026.

We continue to value input from stockholders concerning our executive compensation program and will continue to consider any such feedback when making design adjustments.

Analysis of 2025 Compensation

**Analysis of 2025 Compensation**

**Core Compensation Elements**

The 2025 executive compensation program primarily consisted of the following core compensation elements: base salary, short-term (annual) incentive compensation, and long-term equity incentive compensation in the form of restricted stock units ("RSUs") and performance stock units ("PSUs"). Each element is intended to reward and motivate executives in different ways consistent with our overall compensation philosophy. Each of these compensation elements for our NEOs for fiscal year 2025 is discussed in detail below, including a description of the particular element and how it fits into our overall executive compensation philosophy and objectives.

**Base Salary**

The base salary payable to each NEO is intended to provide a fixed component of compensation reflecting the executive's skill set, experience, role, and responsibilities. We believe that a competitive base salary is a necessary element of our executive compensation program and is critical in attracting and retaining executive talent. Base salaries for our NEOs are intended to be competitive with salaries received by other individuals in similar positions at the companies with which we compete for talent, as well as equitable internally across our executive team.

Base salaries for our NEOs were established initially through negotiations at the time each individual was hired. Subsequent adjustments to base salaries were based on such individual's performance and promotion, as well as positioning relative to market data, our own analysis of compensation practices at peer companies, internal pay equity considerations, and contractual terms. In making decisions regarding salary adjustments, our Board (for the CEO) or Compensation Committee also draw upon the experience that members of our Compensation Committee or Board, as applicable, have within our industry. We do not assign a specific weight to any single factor in making decisions regarding base salary adjustments. If appropriate, base salaries are adjusted on an annual basis.

Based on the foregoing, the Compensation Committee and Board, as applicable, approved the following base salary increases for our NEOs effective April 1, 2025.

**Short-Term Incentive Compensation**

On February 25, 2025, the Compensation Committee adopted and approved the terms of the Company's executive short-term incentive compensation program (the "STIP") for fiscal year 2025, which provides eligibility

2026 PROXY STATEMENT 55

Analysis of 2025 Compensation

for annual cash incentive awards to certain executives of the Company (including each of the Company's NEOs). Payments under the STIP are based on the achievement of predetermined corporate performance goals approved by the Board that are important objectives for our business and are designed to drive our growth as a company and long-term shareholder value. For fiscal year 2025, Messrs. Logan and Schopfer's and Mses. Lee and Ulrich's Corporate performance goals under the STIP were based 100% on the Enterprise metrics set forth below and as Group President of the Nuclear & Safety Group, 70% of Mr. Eloy's performance goals were based on the Nuclear & Safety Group metrics and 30% of Mr. Eloy's performance goals were based on the Enterprise metrics, both set forth below.

Actual payouts under the STIP may also be adjusted by an individual performance adjustment modifier. The individual performance adjustment modifier is intended to incentivize our executives by permitting the Compensation Committee, or the Board as applicable, to reward exceptional performance and penalize poor performance. The individual performance modifier, if applied, has a cap of 30%.

The Compensation Committee did not make any discretionary individual performance adjustments for our NEO's 2025 performance and therefore did not apply any individual performance adjustment modifiers to the 2025 STIP payments for the NEOs.

The specific targets relating to the performance goals were set in connection with the establishment of the Company's annual operating budget for the 2025 fiscal year. In connection with its review and approval of the STIP, our Compensation Committee reviewed the target incentive opportunities of our NEOs, taking into consideration several factors, including a competitive market analysis performed by WTW, our Company's overall financial and operational results for the prior fiscal year, the performance of the individual executive officer, the executive officer's potential to contribute to our long-term strategic goals, role and scope of responsibilities within our Company, individual experience and skills, the Compensation Committee's sense of competitive market practices for annual incentives and the recommendations of our CEO (for NEOs other than himself). Based on the foregoing, the Compensation Committee approved the target incentive opportunities (expressed as a percentage of 2025 base salary) for our NEOs for fiscal year 2025 set forth in the table below, which were unchanged from the 2024 target incentive opportunities. Messrs. Schopfer and Eloy, and Mses. Lee and Ulrich each have a maximum bonus payout percentage of 200% of their applicable target incentive opportunities, based on respective performance goal achievement only, whereas Mr. Logan has a maximum bonus payout percentage of 200% of his base salary (and not his target incentive opportunity), based on corporate performance goal achievement only.

**Long-Term Equity Incentive Compensation**

We believe that providing long-term incentive compensation in the form of equity awards is a critical element of our executive compensation program as it reinforces our pay-for-performance culture and aligns employees' interests and contributions with the long-term interests of the Company's stockholders. In addition, our Compensation Committee and Board believe that offering meaningful equity ownership in the Company is helpful in retaining our NEOs and other key employees.

2026 PROXY STATEMENT 57

Analysis of 2025 Compensation

In March 2025, the grants made to Messrs. Logan, Schopfer and Eloy pursuant to the Company's Omnibus Incentive Plan (the "Incentive Plan") were 100% PSUs whereas the grants to our other NEOs were 40% RSUs and 60% PSUs. Because the value of RSUs and PSUs is based on the price of our Class A common stock when the RSUs and PSUs vest, we believe RSUs and PSUs provide meaningful incentives to motivate NEOs to increase the value of our stock over time. In addition, the Compensation Committee believes PSUs continue to drive important business objectives that, in turn, drive long-term stockholder value. In determining the number of RSUs and PSUs to be granted, as well as the allocation between RSUs and PSUs, our Compensation Committee considered several factors, including a competitive market analysis performed by WTW, the performance of the individual executive officer, the executive officer's potential to contribute to our long-term strategic goals, role and scope of responsibilities within our Company, individual experience and skills, the Compensation Committee's sense of competitive market practices for annual long-term incentive compensation and the recommendations of our CEO (for NEOs other than himself), resulting to a shift to 100% PSUs for Messrs. Logan, Schopfer and Eloy. The RSUs and PSUs granted to our NEOs in 2025 were as follows:

*RSUs*

The RSUs vest in three equal annual installments beginning on the first anniversary of the vesting effective date, subject to the NEO's continued employment through each vesting date. In offering RSUs, our Compensation Committee aimed to attract and retain executive talent while aligning the interests of our executives with those of our shareholders.

*PSUs*

The PSUs granted in 2025 (the "2025 PSUs") are eligible to vest following the end of a three-year performance period from January 1, 2025 through December 31, 2027, subject to the Compensation Committee's certification of the Company's achievement of specified performance goals related to adjusted EBITDA (weighted 50%) and management adjusted free cash flow (weighted 50%) as described in more detail below, which may be modified by 25% upward or downward based on the Company's relative total shareholder return during the performance period ("Relative TSR"), and subject further to the applicable NEO's PSU agreement terms. In order for the PSUs to vest, the applicable NEO must be continuously employed through the date of the Compensation Committee's certification. The number of shares that may be earned are capped at 250% of target with the number based on our performance against these metrics, which are key measures of our long-term performance, as well as the change in the price of Class A common stock. In offering PSUs, our Compensation Committee considered several factors, including the executive officer's potential to contribute to our long-term strategic goals and the performance metrics that have the most significant impact on our long-term goals. Accordingly, the Compensation Committee determined that it was in the best interests of the Company to grant to the most senior executives of the Company only PSUs (and not RSUs) because of the influence that these individuals have on the Company's ability to achieve these key performance metrics.

*Adjusted EBITDA Metrics*

50% of the total 2025 PSU award earned by our NEOs will be based on the Company's achievement of certain adjusted EBITDA metrics, ending calendar year 2027. The adjusted EBITDA metrics are as follows:

Analysis of 2025 Compensation

| | | |
|:---|:---|:---|
| | **Performance Metric ($M)** | **Payout (% of Target Number of PSUs)** |
| Minimum | $267 | 50% |
| Target | $292 | 100% |
| Maximum | $317 | 200% |

---

Adjusted EBITDA is similarly defined as for the STIP. The payout based on the adjusted EBITDA metrics will be linearly interpolated. In no event will the NEOs be eligible to receive more than 200% payout for the adjusted EBITDA performance goal.

After careful consideration, the Committee determined that the limited use of overlapping performance conditions across our STIP and LTIP is appropriate, well-calibrated and consistent with our pay-for-performance philosophy. The Committee selected Adjusted EBITDA and other overlapping metrics because they represent core indicators of the Company's operating performance and are directly linked to the execution of our strategic plan. The Committee believes that reinforcing these priorities across multiple incentive vehicles promotes sustained management focus on disciplined growth, profitability and operational execution. The Committee structured each incentive program to ensure that the use of overlapping metrics does not result in duplicative compensation for the same performance outcomes. While certain metrics may be common across the STIP and LTIP, each program applies district performance periods, payout curves, leverage and maximum payout limitations. Annual incentive awards emphasize near-term execution and are subject to annual performance thresholds and caps, while long-term incentive awards are measured over multi-year performance periods and are further aligned with stockholder interests through equity based delivery, vesting requirements, and long-term value considerations.

The Committee also assessed the rigor of performance goals used in each program independently. Performance targets are established annually based on the Company's operating plan and long-term outlook and achievement of threshold, target and maximum performance levels requires progressively stronger financial results. The Committee believes this calibration ensures that the payouts under each program appropriately reflect the level of performance achieved and mitigates the risk of excessive compensation outcomes.

In designing the program the Committee concluded that the selective overlap of performance metrics, differentiated design features and appropriate targets supports transparency, reinforces accountability and strengthens alignment between executive compensation and stockholder value creation. Accordingly the Committee believes that the Company's incentive structure appropriately balances short-term and long-term performance objectives and avoids undue duplication of pay opportunities.

*Management Adjusted Free Cash Flow Metrics*

The other 50% of the total 2025 PSU award earned by our NEOs will be based on the Company's achievement of certain management adjusted free cash flow metrics, cumulative for the three-year performance period. The management adjusted free cash flow metrics are as follows:

---

| | | |
|:---|:---|:---|
| | **Performance Metric ($M)** | **Payout (% of Target Number of PSUs)** |
| Minimum | $545 | 50% |
| Target | $595 | 100% |
| Maximum | $645 | 200% |

---

Management adjusted free cash flow is defined as adjusted EBITDA plus the cash impact from net working capital and capital expenditures. The payout based on the management adjusted free cash flow metrics will be

2026 PROXY STATEMENT 59

------

Analysis of 2025 Compensation

linearly interpolated. In no event will the NEOs be eligible to receive more than 200% payout for the management adjusted free cash flow performance goal.

*Total Shareholder Return Metrics*

Once initial payout in respect to the 2025 PSUs is determined based on adjusted EBITDA and management adjusted free cash flow achievement, the initial payout may be modified based on the Company's Relative TSR achievement, measured against the Russell 2000 Industrials Index, to determine final payout. The Russell 2000 Industrials index was chosen as the comparator group for measuring Relative TSR because it is relevant to the current industrial focus of the Company. The following targets were set with respect to the Relative TSR performance goal:

---

| | | |
|:---|:---|:---|
| | **Percentile Rank** | **Modifier Range** |
| Minimum | <30th | -25% |
| Target | 55th  | 0% |
| Maximum | ≥80% | 25% |

*2025 Vesting events:*

*2022 PSUs*

The Company granted PSUs on April 1, 2022, with a 3-year performance period commencing April 1, 2022 and ending March 31, 2025 (the "2022 PSUs"). The 2022 PSUs vest based on the Company's achievement of certain performance goals relating to relative TSR and organic revenue growth, weighted equally at 50%, and the applicable NEO's continued employment through the end of the performance period and the date the Compensation Committee certifies achievement of the performance goals. The relative TSR goal was achieved at 182.40% and the organic revenue growth goal was achieved at 200%, resulting in overall payout of 2022 PSUs equal to 191.20% of target. The 2022 PSUs vested in May 2025.

**Other Elements of Compensation**

**Retirement Plans**

We maintain a 401(k) retirement savings plan for our employees in the United States, who satisfy certain eligibility requirements. The 401(k) plan provides eligible U.S. employees with an opportunity to save for retirement on a tax advantaged basis. Participants include Messrs. Logan and Schopfer and Mses. Lee and Ulrich. Messrs. Logan and Schopfer and Mesdames Lee and Ulrich are eligible to participate in the 401(k) plan on the same terms as other full-time employees, including with respect to matching contributions, which, during 2025, was equal to 100% of a participating employee's contribution up to the first 2% of the employees' eligible compensation and 50% of the employees' contribution up to the next 4% of the employee's eligible compensation. Mr. Eloy participates in France's mandatory social security and supplementary pension scheme

2026 PROXY STATEMENT 60

Analysis of 2025 Compensation

on the same terms as other French full-time employees of the French Subsidiary, as more specifically described in "<u>[Employee Benefits and Perquisites](#i1a66a65e36fc472ab7aca46b1f1b58af_5494)</u>" below.

**Nonqualified Deferred Compensation Plan**

We maintain an unfunded, nonqualified deferred compensation plan (the "Deferred Compensation Plan"), in which Mr. Logan and Mses. Lee and Ulrich, have historically participated. Each year, eligible employees, which includes our U.S. executive officers, including our U.S. NEOs, can elect to defer up to 100% of their base salary, bonus, commissions and/or short-term incentive compensation, as applicable, under the Deferred Compensation Plan. We do not make any matching, discretionary or other similar contributions to the Deferred Compensation Plan on behalf of participants.

Participants may elect to receive compensation they have deferred upon certain qualifying distribution events (e.g., separation from service, death, disability or at a specified date) at which time account balances are distributed in cash either in a lump sum or annual installments as elected by the participant. If no election is made, account balances are distributed in a lump sum. Annual installments can be for up to five years if the qualifying distribution event is a specified date or 15 years if the qualifying distribution event is due to a separation from service. Account balances are distributed in a single lump sum to the participant's beneficiary upon the participant's death or disability. Participants may also elect to receive in a single lump sum, in the event of a separation from service within two years of a change in control of the Company, the entire vested portion of their account balance that was otherwise reserved for payment in installments following a separation from service or at a specified date.

Account balances under the Deferred Compensation Plan are credited with a deemed investment return (or credited with a deemed investment loss), determined as if the account was invested in one or more of approximately 20 investment funds made available by the administrator. Participants elect the investment fund(s) in which accounts will be deemed invested. Participants may change their investment elections on a daily basis. The investment vehicle is determined by the administrator if the participant fails to make an investment election.

**Employee Benefits and Perquisites**

All of our full-time employees in the United States, including Messrs. Logan and Schopfer and Mses. Lee and Ulrich, are eligible to participate in health and welfare plans, including medical, dental and vision benefits, medical and dependent care flexible spending accounts, short-term and long-term disability insurance and life insurance.

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. However, we have provided certain perquisites to our NEOs in situations where we believe it is appropriate to assist an individual in the performance of their duties, to make him or her more efficient and effective, and to provide a competitive compensation package for recruitment and retention purposes. Mr. Eloy is entitled to certain French-related benefits due to his employment in France.

In fiscal year 2025, all of the NEOs in the United States were entitled to (i) company-paid premiums for long-term care insurance in the United States, (ii) reimbursement for the costs of an annual physical examination, and (iii) financial planning services.

Pursuant to the terms of Mr. Logan's employment agreement, in fiscal year 2025 we also reimbursed Mr. Logan for certain automobile expenses.

Pursuant to the terms of Mr. Eloy's employment agreement, we provided Mr. Eloy with a Company-leased automobile for business and personal use including the cost of maintenance, tolls and gas. We also made contributions to France's mandatory social security and supplementary pension scheme (managed by AGIRC/ARRCO) for Mr. Eloy in accordance with French law and the applicable local bargaining agreement applicable to all employees of Mirion Technologies (MGPI) SAS, a French subsidiary of the Company and Mr. Eloy's French employer (the "French Subsidiary"). In addition, we made contributions on behalf of Mr. Eloy to the Garantie Sociale du Chef d'enterprise (GSC) for purposes of providing unemployment benefits to Mr. Eloy in the event of involuntary termination. Such contributions are intended to replace French-provided unemployment benefits, which are unavailable to Mr. Eloy due to his officer position with the French Subsidiary.

**Employment and Severance Arrangements**

*Logan Employment Agreement*

On August 15, 2006, the Company entered into an employment agreement with Mr. Logan, which was subsequently amended and restated and most recently amended on December 27, 2021 (as amended, the "Logan Employment Agreement"), providing for his employment as Chief Executive Officer of the Company. The Logan Employment Agreement provides that Mr. Logan was entitled to an annual base salary of $700,000 and was eligible for an annual incentive bonus targeted at one hundred percent (100%) of annual base salary with the potential to receive up to one hundred and fifty percent (150%) of annual base salary, based on the Company's achievement of certain performance metrics as determined by the Compensation Committee. Effective as of April 1, 2025, Mr. Logan's annual base salary was $825,000 and his annual incentive bonus was 120% of his annual base salary. In December 2021, Mr. Logan was also eligible to receive a one-time retention/bridge equity incentive grant having a target total grant date value equal to $6,000,000 (2/3 of which was in the form of time-vesting restricted stock units (the "RSUs") and 1/3 of which was in the form of performance-vesting restricted stock units (the "PSUs")). In addition, for each calendar year occurring during Mr. Logan's employment term, Mr. Logan will be eligible to receive an annual long-term equity incentive grant having a target total grant date value equal to $2,700,000, in a mix of RSUs and PSUs, as determined by the Compensation Committee in its discretion. Furthermore Mr. Logan is entitled to reimbursement for reasonable and necessary business expenses, which includes, but is not limited to, (i) reimbursement for first class air travel expenses, (ii) the cost of an annual local executive physical examination up to $10,000, and (iii) the costs of annual financial planning services, up to $5,000 per year.

2026 PROXY STATEMENT 66

Analysis of 2025 Compensation

*Executive Severance Plan*

Our compensation committee has adopted an Executive Severance Plan, or the Severance Plan, which applies to certain employees but not any of our executive officers with whom we have entered into an employment agreement. Ms. Ulrich is currently the only NEO who participates in the Severance Plan. In February 2025, the Compensation Committee approved certain amendments to Ms. Ulrich's Executive Severance Plan Participation Agreement. Specifically, her participation was amended to (i) increase the severance multiplier to 1.0x her then current base salary (increased from 0.5x, as described above) and (ii) increase the payment of, or reimbursement for the cost of, her COBRA premium payments for a period ending on the earlier of twelve (12) months or the date on which she becomes eligible for health coverage from a subsequent employer. The Severance Plan provides that upon a participant's termination by the Company for any reason other than due to death, disability or "cause" or Ms. Ulrich's resignation for "good reason", as each is defined in the Severance Plan (the "Qualifying Termination"), in each case either within or outside of the change in control period (i.e., the period of 12 months after a "change in control," as defined in the Severance Plan), the participant will be entitled to receive, subject to the execution and delivery of an effective and irrevocable release of claims in favor of the Company and continued compliance with all applicable restrictive covenants, (i) twelve (12) months of the participant's then-current base salary, payable in substantially equal installments over twelve (12) months in accordance with the Company's payroll practices, (ii) an amount equal to the participant's prorated annual bonus for the bonus performance period during which the participant's employment terminates, payable in substantially equal installments over twelve (12) months in accordance with the Company's payroll practices, (iii) payment of, or reimbursement for the cost of, the participant's COBRA premium payments (for the participant and the participant's dependents) (less the portion of any such premiums that the participant would have been required to pay for the participant and the participant's dependents had the participant continued to be employed) for a period ending on the earlier of twelve (12) months or the date on which the participant becomes eligible for health coverage from a subsequent employer, and (iv) any earned but unpaid bonus in respect of the most-recent bonus performance period ending prior to the termination date, payable when the bonus would have normally been paid (or upon the release effective date, if later). In addition, (a) upon a Qualifying Termination outside of the change in control period, a participant shall be entitled to six (6) months of accelerated vesting with respect to the participant's equity awards as if the participant had remained employed for the six (6) month period immediately following the termination date and (b) upon a Qualifying Termination within the change in control period, the participant shall be entitled to (x) an amount equal to 50% of the participant's target annual bonus and (y) following the assumption of the participant's equity awards in connection with the change in control, full accelerated vesting of such equity awards, with any equity awards that vest based on performance to be vested at target level.

In the event the severance and other benefits provided in the Severance Plan or otherwise payable to Ms. Ulrich under any other plan or arrangement (i) constitute "parachute payments" within the meaning of Section 280G of the Code (the "280G Payments"), and (ii) otherwise would be subject to the excise tax imposed by Section 4999 of the Code (the "Excise Tax"), then the 280G Payments will be either (a) delivered in full or (b) delivered as to such lesser extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing amounts, taking into account the applicable federal, state and local income taxes and the excise tax imposed by Section 4999 of the Code, results in the receipt by Ms. Ulrich on an after-tax basis, of the greatest amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under Section 4999 of the Code.

*Equity Award Agreements*

In addition to the severance benefits in the applicable employment agreements and Severance Plan, the RSU and PSU award agreements for our NEOs also contain certain provisions for acceleration of the vesting. For a fulsome description of what the equity award agreements provide for under certain termination of employment, see Potential Payments upon Termination or Change in Control on page 78.

**Other Compensation Governance Practices**

Stock Ownership Policy

The Compensation Committee believes that purchasing and holding shares of our common stock creates an incentive to manage the Company prudently and established minimum stock ownership requirements for our directors, NEOs and certain other employees in a Stock Ownership Policy adopted in November 2021 and last amended on February 25, 2025.

| (2) Annual cash retainer does not include additional payments for committee Chair or Lead Director roles. | (2) Annual cash retainer does not include additional payments for committee Chair or Lead Director roles. |

---

The value of the stock ownership requirement is based on the applicable individual's then current cash retainer or salary and the value of the stock holdings is based on the average closing price of a share of the Company's stock for the previous calendar year. Shares owned outright, unvested restricted stock, RSUs and shares or share equivalent units underlying deferred fees paid to non-employee directors are included in the calculation of share ownership.

Participants have five years to achieve these requirements and must retain all of their net shares received as a result of the vesting, payment or distribution of any RSUs, PSUs or other equity awards, excluding any shares sold or withheld to pay any applicable taxes, until this requirement is met.

All participants are currently in compliance with the Stock Ownership Policy.

Clawback Policy

The Company's Clawback Policy, first adopted in 2021, is designed to comply with Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Action of 2010, Section 10D of the Securities Exchange Act of 1934, as amended, and the listing standards of The New York Stock Exchange (the "NYSE"). It provides that in the event the Company is required to prepare an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under securities laws, the Board will require reimbursement to the Company of any performance-based award made to any executive officer and other covered executives of the Company where: (i) the payment was predicated upon achieving certain financial results that were subsequently the subject of either a "Big R" or "Little r" restatement of Company financial statements filed with the SEC; and (ii) a lower payment would have been made to such executive officers and other covered executives based upon the restated financial results. In each such instance, the Company will reasonably promptly recover from the executive officers and other covered executives the amount in excess of what would have been awarded based on the corrected performance measures for the Applicable Recovery Period defined as the three (3) completed fiscal years immediately preceding the date of the restatement.

Analysis of 2025 Compensation

Policy for the Granting of Equity-Based Awards

In November 2023, the Company adopted a Policy for the Granting of Equity-Based Awards, describing its processes for the granting of shares of common stock or derivatives thereof, including RSUs, PSUs and/or other equity-based awards. The Policy for the Granting of Equity-Based Awards provides that grants of equity-based awards made in conjunction with the hiring of a new employee or the promotion of an existing employee will be made on a regular monthly basis on the first day of each month, to ensure that equity awards cannot be timed to take advantage of material nonpublic information. Grants of equity-based awards to existing employees (other than in connection with a promotion) will be made, if at all, on an annual basis and considered and approved by the Compensation Committee at a meeting to be held in February of each year or shortly thereafter. Our Compensation Committee carefully reviews any potential material nonpublic information before granting equity awards. We do not time our equity award grants either to take advantage of a depressed stock price, or an anticipated increase in stock price, and we have limited the amount of discretion that can be exercised in connection with the timing of equity award grants. We also do not time the release of material nonpublic information based on equity award grant dates. The Policy for the Granting of Equity-Based Awards further provides that all equity-based awards must be priced on their respective grant date.

The Company did not grant awards of stock options, stock appreciation rights or similar option-like instruments during fiscal 2025.

Risk Assessment in Compensation Programs

We believe our compensation programs encourage and reward prudent business judgment without encouraging undue risk. The Compensation Committee reviews our compensation programs for features that might encourage inappropriate risk-taking. We believe our compensation policies and practices do not create risks that are reasonably likely to have a material adverse effect on us. In addition, our independent compensation consultant has conducted a third party high-level assessment of potential compensation risk and has concluded the same.

**Tax and Accounting Considerations**

Deductibility of Executive Compensation

Section 162(m) of the Internal Revenue Code (Section 162(m)) generally imposes a $1 million cap on the federal income tax deduction for compensation paid to our "covered employees" (which includes our NEOs and certain former executive officers) during any fiscal year. While the Compensation Committee acknowledges the deductibility of awards as a factor in determining executive compensation, the Compensation Committee looks at other factors in making its decisions, and, in the exercise of its business judgment and in accordance with its compensation philosophy, the Compensation Committee retains the flexibility to award compensation even if the compensation is not deductible by us for tax purposes, and to modify compensation that was initially intended to be tax deductible if it determines such modifications are consistent with our business needs.

Accounting for Stock-Based Compensation

The Compensation Committee takes accounting considerations into account in designing compensation plans and arrangements for our NEOs and other employees. We follow ASC Topic 718 for our stock-based compensation awards which requires us to measure the compensation expense for all share-based payment awards based on the grant date "fair value" of these awards.

Taxation of "Parachute" Payments

Sections 280G and 4999 of the Code provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of the Company that exceeds certain prescribed limits, and that the Company (or a successor) may forfeit a deduction on the amounts subject to this additional

2026 PROXY STATEMENT 69

tax. We do not provide any executive officer, including any NEO, with a "gross-up" or other reimbursement payment for any tax liability that the executive officer might owe as a result of the application of Sections 280G or 4999 of the Code.

Section 409A of the Internal Revenue Code

Section 409A of the Code imposes additional significant taxes in the event that an executive officer, director or service provider receives "deferred compensation" that does not satisfy the requirements of Section 409A of the Code. We structure all our nonqualified deferred compensation plans, severance arrangements, bonus arrangements and equity awards in a manner to either avoid the application of Section 409A or, to the extent doing so is not possible, to comply with the applicable requirements of Section 409A of the Code.

In addition, the amount reported also includes a portion of the retention bonus paid to Mr. Schopfer on October 7, 2022 (the "Schopfer Retention Bonus") that is not required to be repaid by Mr. Schopfer upon such termination of employment.

(2) Cash severance upon termination without Cause or for Good Reason in connection with a change in control includes (i) 200% of the sum of base salary and target bonus (100% of the sum of base salary and target bonus in the case of Mr. Schopfer and Mses. Lee and Ulrich), and (ii) a pro-rata portion of the annual incentive bonus for the fiscal year in which the termination occurs. In addition, the amount reported for Mr. Schopfer also includes the amount of the Schopfer Retention Bonus that is not required to be repaid by Mr. Schopfer upon such termination of employment.

(3) Cash severance upon death or disability includes a pro-rata portion of the annual incentive bonus for the fiscal year in which the termination occurs. For Mr. Schopfer, the amount reported also includes the amount of the Schopfer Retention Bonus that is not required to be repaid by Mr. Schopfer upon such termination of employment.

(4) Acceleration of vesting of equity was calculated based on the market value of the shares underlying each of the outstanding equity awards, based on the closing price of our Class A common stock on the New York Stock Exchange on the last trading day of fiscal year 2025, December 31, 2025, which was $23.42.

**Pay Versus Performance**

As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation and the financial performance of our Company. The disclosure included in this section is prescribed by SEC rules and does not necessarily align with how the Company or the Compensation Committee view the link between the Company's performance and its NEOs pay. For additional information on our compensation programs and philosophy and how we design our compensation programs to align pay with performance, see the section titled "<u>[Compensation Discussion and Analysis](#iae13da6fe8044c5a8225aacc6fa1e8d5_142)</u>".

The table below presents information on the compensation of our chief executive officer (principal executive officer or "PEO") and our other NEOs in comparison to certain performance metrics for the covered fiscal years. Net Income (Loss) is not a metric that the Compensation Committee uses when setting executive compensation, but is required by Item 402(v) of Regulation S-K to be used as a performance metric in this disclosure. The use of the term "compensation actually paid" ("CAP") is required by the SEC's rules. Neither CAP nor the total amount reported in the Summary Compensation Table reflect the amount of compensation actually paid, earned or received during the applicable year. Per SEC rules, CAP was calculated by adjusting the Summary Compensation Table Total values for the applicable year as described in the footnotes to the table. Note, the CAP values for fiscal periods July 1, 2021 – December 31, 2021 through January 1, 2024 – December 31, 2024 for both our chief executive officer and other NEOs as reported in the table below are driven by the issuance of profits interests awards made by the Sponsor in connection with the Business Combination which vest dependent upon the achievement of specified share price conditions. The profits interests awards achieved their respective stock price conditions and subsequently vested on November 12, 2024 and December 17, 2024.

For a reconciliation of Adjusted EBITDA to net income (loss), please see the reconciliation below under "Tabular List of Performance Measures." Adjusted EBITDA used for our compensation programs differs from reported adjusted EBITDA due to adjustments to remove impacts of current year acquisitions and setting foreign exchange impacts at the targeted exchange rates. |

*Description of the Relationship Between Compensation Actually Paid and Performance Metrics*

The Company's Compensation Committee reviews a variety of Company-wide and individual factors to link executive compensation actually paid with Company and executive performance, not all of which are presented in the Pay versus Performance table above. To promote strong pay-for-performance orientation when setting executive pay levels, the Compensation Committee considers the Company's absolute and relative TSR, short- and long-term business outlook, including net income and Adjusted EBITDA, and the broader market environment. Moreover, the Company calculates compensation to the PEO and other NEOs on a basis different than the amount reported in the Summary Compensation Table and CAP presented in the Pay Versus Performance table, as calculated in accordance with Item 402(v) of Regulation S-K, is not considered by the Board and the Compensation Committee in evaluating or determining executive compensation.

Executive Compensation Tabular Disclosures

In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between compensation actually paid and the financial performance metrics presented in the Pay Versus Performance table. We note, however, that since the five reported periods vary in length, CAP and Company performance may not be immediately comparable on a period-by-period basis. That said, we believe the Pay Versus Performance table shows the alignment between CAP to the NEOs and the Company's performance, consistent with our compensation philosophy as described in our CD&A. Specifically, CAP for the Company's PEO decreased from $53,333,639 in Fiscal Year 2024 to $10,926,024 in the most recently completed fiscal period disclosed, and also decreased for the Company's average non-PEO NEO from $4,457,847 to $2,104,174 over the same comparable fiscal periods. Despite the decrease in CAP, which is largely attributed to the vesting of profits interests awards in 2024, the Company TSR increased from the last fiscal period disclosed to the most recently completed fiscal period. Further, Adjusted EBITDA, the primary measure used by the Committee to link pay and performance, increased from $203,600,000 in Fiscal Year 2024 to $227,900,000 in the most recently completed fiscal period. Finally, our net income increased from a loss of ($36,600,000) in Fiscal Year 2024 to a gain of $29,800,000 in the most recently completed fiscal period.

***Tabular List of Performance Measures***

On October 20, 2021 (the "Closing" or the "Closing Date"), Mirion Technologies (Topco), Ltd. ("Mirion TopCo") consummated its business combination (the "Business Combination") with GS Acquisition Holdings Corp II ("GSAH"). On the Closing Date, GSAH was renamed Mirion Technologies, Inc. As a result of the Business Combination, Mirion's financial statement presentation distinguishes Mirion TopCo as the "Predecessor" for periods prior to the closing of the Business Combination and Mirion Technologies, Inc. as the "Successor" for periods after the Closing. As a result of the application of the acquisition method of accounting for the Successor, the financial statements for the periods following the Closing are presented on a full step-up basis as a result of the Business Combination, and are therefore not comparable to the financial statements of the Predecessor that are not presented on the same full step-up basis due to the Business Combination.

As required by the SEC rules, the Company has determined the following as its most important measures used to link compensation actually paid to our NEOs to company performance for fiscal year 2025, which are the only financial performance measures used to link compensation actually paid to company performance for fiscal year 2025.

| Adjusted EBITDA |
| Adjusted Free Cash Flow |

We use financial measures for performance-based compensation purposes, including Adjusted EBITDA and Adjusted Free Cash Flow and Adjusted Organic Revenue, that are not measures of financial performance under GAAP, in particular as compensation targets and for the performance measures described above herein. We believe that non-GAAP financial information, when taken collectively, may be helpful to management and investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business.

Adjusted EBITDA is defined as GAAP net income before interest expense, income tax expense, depreciation and amortization adjusted to remove the impact of foreign currency gains and losses, amortization of acquired intangible assets, the impact of purchase accounting on the recognition of deferred revenue, changes in the fair value of warrants, certain non-operating expenses (impairment related to a business held for sale and an equity investment, incremental one-time costs related to the Business Combination, incremental one-time costs associated with becoming a public company, mergers and acquisition expenses, restructuring costs, costs to achieve information technology system integration and efficiency, and costs to achieve integration and operational synergies), stock-based compensation expense, debt extinguishment, goodwill impairment, and the income tax impacts of these adjustments. Adjusted EBITDA used for our compensation programs differs from reported adjusted EBITDA due to adjustments to remove impacts of current year acquisitions and setting foreign exchange impacts at the targeted exchange rates. A reconciliation of Adjusted EBITDA to the most comparable GAAP measure is set forth in the tables that follow.

Relative TSR is defined as the Total Shareholder Return for Mirion during the relevant performance period measured as a comparative percentile to all companies in the Russell 2000 Industrials index. Total Shareholder Return is the share price appreciation of any particular company's publicly traded common stock plus dividends accrued, as measured during the applicable performance period.

See the "<u>[Compensation Discussion and Analysis](#iae13da6fe8044c5a8225aacc6fa1e8d5_142)</u>" above and published in the Company's historical proxy statements for additional detail on executive compensation actions. Note, the compensation value ultimately realized by the Company's executive officers remains subject to significant variation over time (e.g., forfeiture of unvested awards prior to vesting, variation in stock price prior to award monetization).

(1) Includes the "Company's Omnibus Incentive Plan".

(2) Represents 3,903,859 shares of Class A common stock subject to RSUs and PSUs outstanding as of December 31, 2025. RSUs and PSUs do not have an exercise price. The number of securities to be issued with respect to the settlement of PSUs reflect the maximum number of shares under best-case achievement of the underlying performance metrics.

(3) As of December 31, 2025, an aggregate of 38,221,906 shares of Class A common stock were available for issuance under the Incentive Plan assuming maximum number of shares issued for outstanding PSUs. The number of shares of Class A common stock reserved for issuance under the Incentive Plan will automatically increase on the first day of each fiscal year through and including January 1, 2031 by the lesser of (i) 3% of the total number of outstanding shares of Class A common stock on the last day of the immediately preceding fiscal year, (ii) 9,976,164 shares of the Class A common stock and (iii) such number of shares of Class A common stock as determined by the compensation committee of our board of directors. If an award expires or is cancelled or forfeited, or is otherwise settled without the issuance of shares, the shares covered by the award will again be available for issuance under the Incentive Plan. Shares tendered or withheld to pay or satisfy the exercise price of a stock option or SAR or to pay taxes in respect of any stock option or SAR, will again be available for issuance under the Incentive Plan. Shares underlying replacement awards (i.e., awards granted as replacements for awards granted by a company that we acquire or with which we combine) will not reduce the number of shares available for issuance under the Incentive Plan.

Certain Relationships and Related Party Transactions

**Ratio of Annual Compensation for the CEO to our Median Employee**

As required in Item 402(u) of Regulation S-K, we have estimated the ratio of the 2025 annual total compensation of our CEO to the annual total compensation of our median employee was 97 to 1, calculated as follows:

For fiscal year 2025, the CEO's total annual compensation was $7,035,470.

The median of annual total compensation for all employees was $72,676.

The CEO's total annual compensation was approximately 97 times that of our median employee.

As a global organization, approximately 50% of our almost 2,900 employees were located outside of the United States as of December 31, 2025. The countries with our largest number of employees are the United States, France, and Germany. Consistent with our executive compensation program, our global compensation program is designed to be competitive in terms of both the position and the geographic location in which an employee is located. We identified our median employee based on base salary of all our global employees as of December 31, 2024. We chose this as our consistently applied compensation measure because we believed it was representative of employee compensation at the Company. In identifying the median employee, we converted compensation amounts paid in foreign currencies based on the exchange rate on December 31, 2024, provided by Yahoo Finance and annualized the compensation of individuals who joined our Company during 2024. We did not make any cost-of-living adjustments. The median employee was employed in the United States and serves as a Functional Manager. We calculated the median employee's compensation under the Summary Compensation Table rules and compared that to the annual total compensation of our CEO, as disclosed in the Summary Compensation Table. As permitted by Item 402(u) of Regulation S-K, we used the same median employee for 2025 as we did for 2024, but updated the median employee's compensation as described in the prior sentence.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with SEC rules based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may utilize different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios.

Proposal No. 3 - Advisory Vote to Approve Compensation of Named Executive Officers

![wide-header-box.jpg](mir-20260401_g7.jpg)

**Proposal No. 3**

**Non-Binding Advisory Vote to Approve Compensation of Named Executive Officers**

In accordance with the requirements of Section 14A of the Exchange Act and Exchange Act Rule 14a-21(a), we are including in this proxy statement a separate resolution to approve, in a non-binding, stockholder advisory vote, the compensation paid to our named executive officers as disclosed in "<u>[Executive Compensation](#iae13da6fe8044c5a8225aacc6fa1e8d5_172)</u>" above. This vote is a non-binding, stockholder advisory vote on executive compensation (or "say-on-pay vote").

The Board believes that our executive compensation programs align the interests of stockholders and executive officers by emphasizing variable, at-risk compensation through a combination of long-term equity incentives and annual cash incentives. We encourage you to read the disclosure under "<u>[Compensation Discussion and Analysis](#iae13da6fe8044c5a8225aacc6fa1e8d5_142)</u>" to learn more about our executive compensation programs and policies.

While the results of the say-on-pay vote are non-binding and advisory in nature, our Board and Compensation Committee intend to consider the results of this vote in making future compensation decisions.

Our Board currently intends to conduct advisory votes on executive compensation every year and our next advisory say-on-pay vote will take place at our 2026 Annual Meeting.
