PROXY STATEMENT

While CMS and Consumers are established, operated and regulated as separate legal entities, CMS and Consumers have the same individuals serving as members on each Board of Directors and each Board Committee and have adopted coordinated Director and executive compensation arrangements and plans as well as auditing relationships. Although in certain contexts in this Proxy Statement the terms “we” and “our” refer to each of CMS and Consumers and satisfy their respective disclosure obligations, this Combined Proxy Statement is separately filed by CMS and Consumers. Information in this Combined Proxy Statement relating to each individual registrant is filed by such registrant on its own behalf. Unless specifically noted, singular references to “Board,” “Committee,” “Corporation” and “Annual Meeting” refer to both CMS and Consumers.

Website references throughout this Proxy Statement are provided for convenience only, and the content on the referenced websites is not incorporated by reference into this Proxy Statement.

OUR PURPOSE

Our purpose is to provide safe, reliable, affordable, clean, and equitable energy in service of our customers. In support of this purpose, we couple digital transformation with the “CE Way,” a lean operating model designed to improve safety, quality, cost, delivery, and employee morale.

We measure our progress toward our purpose by considering our impact on the “triple bottom line” of people, planet, and prosperity; this consideration takes into account not only the economic value that we create for customers and investors, but also our responsibility to social and environmental goals. The triple bottom line balances the interests of employees, customers, suppliers, regulators, creditors, Michigan’s residents, the investment community, and other stakeholders, and it reflects the broader societal impacts of our activities. See our sustainability website for more information at cmsenergy.com/sustainability/default.aspx.

Impact on "Triple Bottom Line" Highlights

•100% Clean Energy Goal - Consumers electric business by 2040

•Net Zero Methane Emissions Goal from Consumers natural gas delivery system by 2030

•Sustainability Report

•Biodiversity Report

•Employees paid fairly and competitively

•Safety Policy

•Business Employee Resource Groups

•91% of our Directors are Independent - 100% on Audit, Compensation, Finance and Governance Committees

•Annual election of all Directors

•Simple majority voting provisions

•Majority voting standard for uncontested Director elections

•Annual Advisory Say-on-Pay Vote

•Policy prohibiting Directors and Officers from pledging or hedging our stock

•Proxy access bylaws

•Annual Board and Committee self-evaluations

•Individual Director peer evaluations

•Chairman of Board is independent and separate from the CEO


CMS ENERGY 2026 PROXY STATEMENT			3

PROPOSAL 1:

ELECT THE DIRECTOR NOMINEES, NAMED IN THIS PROXY STATEMENT, TO THE BOARD OF DIRECTORS

There are 11 nominees for election as Directors of CMS and Consumers, to hold office until the next annual meeting of shareholders and until their successors are elected and qualified. The Board believes that the nominees will be available to serve, but in the event any nominee is unable to do so, the proxies will be voted for a substitute nominee designated by the Board or the number of Directors constituting the full Board will be reduced accordingly.

All of the nominees are currently serving as Directors. All 11 nominees have accepted their nomination and agree to serve if elected. Richard Keyes and Diane Leopold were appointed to the Board in February 2026, and are standing for election for the first time at the 2026 Annual Meeting.

The following table highlights the key experience, skills and qualifications for each nominee. The skills and qualifications that are marked below are reviewed by the Governance, Sustainability and Public Responsibility Committee (“Governance Committee”) and the Board when making nomination decisions and reviewing Board succession planning. The fact that a particular skill or qualification is not designated does not mean nominees do not also possess the specific experience or qualification. The table below illustrates how the Board is well-positioned to provide direction and oversight with respect to our overall performance, strategic direction and significant corporate policies.

CMS ENERGY 2026 PROXY STATEMENT			10

CORPORATE GOVERNANCE

Governance Guidelines and Materials

The Board and management continually review and monitor governance trends and best practices. The Board has adopted Amended and Restated Corporate Governance Principles (“Principles”) that reflect corporate and Board practices as well as relevant Securities and Exchange Commission (“SEC”) rules and the New York Stock Exchange (“NYSE”) listing standards. The Governance Committee is responsible for overseeing and reviewing our Principles at least annually and recommending any proposed changes to the Board for approval. The Principles are intended to serve as a flexible framework within which the Board and its Committees operate. Except for the Executive Committee, the Board has adopted charters for each of the standing Committees that detail their purposes, duties and authority, composition, meetings and resources as well as other aspects of Committee activities (“Charters”), which are further described under Board and Committee Information below. Each Committee reviews its Charter annually and recommends changes to the Governance Committee for review and recommendation to the Board for approval.

The current version of our Principles, Amended and Restated Articles of Incorporation, Amended and Restated Bylaws (“Bylaws”), Charters, Employee and Director Codes of Conduct (“Codes”) and other corporate governance materials are available at cmsenergy.com/corporate-governance/our-view-on-governance/default.aspx.

Board of Directors

The Board provides direction and oversight with respect to our overall performance, strategic direction and significant corporate policies. The Board oversees major initiatives, advises on key financial and business objectives and monitors progress with respect to these matters. Directors are kept informed of our business by management via discussions, presentations and reports on a regular basis, including operating and financial reports made at Board and Committee meetings. The Board has full and direct access to all members of management and may hire consultants and advisors as it deems necessary.

Board Leadership Structure

As stated in our Principles, the Board has determined that for the present time, it is in the best interests of the Corporation and shareholders to keep the offices of CEO and Chairman separate to enhance oversight responsibilities. The Board believes that this leadership structure promotes independent and effective oversight of management on key issues relating to long-range business plans, long-range strategic issues and risks. Additionally, to further promote independent and effective oversight of management, the Board has chosen to appoint a Presiding Director despite the fact that our Principles only require one when the Chairman is not considered independent under NYSE listing standards. The Presiding Director provides the independent Directors with a key means for collaboration and communication. Under our Bylaws, the Presiding Director will: (1) convene and chair meetings of the independent Directors in executive session no less than once each year; (2) preside at meetings of the Board at which the Chairman of the Board is not present, including executive sessions of the independent Directors; (3) solicit independent Directors for advice on agenda items for meetings of the Board; (4) serve as a liaison between the Chairman of the Board, the President and the independent Directors; and (5) perform such other duties as may be assigned by the Board from time to time. Russell, the current Chairman, is not a member of management, but served as President and CEO of CMS and Consumers until July 2016. As of July 2019, he qualified as independent under NYSE listing standards; however, at this time, we still believe it is a best practice to have a Presiding Director and on May 2, 2025, Wright was again elected as Presiding Director, having served in that role since May 2024.

Risk Oversight

The Board's risk oversight process includes regular reports from senior management on areas of material operational, legal, regulatory, financial, strategic, compliance, environmental, liability, safety, information technology, physical security, cybersecurity and reputational risk. The Board receives an annual risk management review in addition to the risk oversight functions performed by the various Committees of the Board. These include: (1) a review by the Audit Committee of the risks associated with operating and financial activities, including a security review, which could impact its financial and other disclosure reporting, as well as a review of policies on risk assessment, controls and accounting risk exposure; (2) the Audit Committee's review and approval of risk management policies; (3) a review by the Compensation and Human Resources Committee (“Compensation Committee”) of the potential risks associated with the Corporation's executive compensation policies and practices; (4) the Compensation Committee's review of management's assessment of the likelihood that the incentive compensation plans will have a material adverse impact; (5) the Finance Committee's review of risks related to corporate finance; and (6) the Governance Committee's review of risks related to governance, public responsibility and sustainability.

Cybersecurity Oversight

The Board is responsible for overseeing the Corporation's cybersecurity risk. Cybersecurity risks are included in the risk reports to the Audit Committee discussed above. These risks are managed through a robust security program that includes people, processes, technology and governance structures. Security is an integrated organization accountable for both cyber and physical security led by the Vice President, IT and Security and Chief Information Officer. Our processes include a review of all security-related projects prior to implementation. A dedicated team monitors our environment and regularly shares threat


CMS ENERGY 2026 PROXY STATEMENT			11

information with peers, and state and federal partners. We also conduct regular drills, exercises, vulnerability assessments and penetration tests to assess the security of our systems. Additional areas of focus include risk management, data privacy and compliance. We have a strong security culture through annual training, which includes courses on a variety of security-related topics. We also conduct monthly phishing tests through our “Don't Take the Bait” program, which asks employees to report suspicious emails that demonstrate common phishing tactics in real-world scenarios. When employees click on a test-phishing email, they are provided with information on cybersecurity best practices. We monitor our “Don't Take the Bait” statistics every month and communicate this data with employees to further emphasize their important role in cybersecurity.

Senior management meets with the Board or Audit Committee at least twice annually to provide updates on and discuss cybersecurity. Such updates include a review of the companies' cybersecurity strategy, a scan of the threat landscape, and recent performance. Additionally, cybersecurity risks are included in the Audit Committee's risk oversight functions, which focus on operating and financial activities that could impact the companies' financial and other disclosure reporting. The Audit Committee's oversight involves reviewing and approving policies on risk assessment, controls, and accounting risk exposure. The Audit Committee also reviews internal audit reports regarding cybersecurity processes, and receives updates that focus on CMS Energy's and Consumers' cybersecurity program, mitigation of cybersecurity risks, and assessments by third-party experts. Given the importance of cybersecurity, in 2015 we elected Directors Soto and Butler, who have extensive subject matter expertise among other qualifications. See Item 1C. Cybersecurity in our Annual Report on Form 10-K for the year ended December 31, 2025 for more information related to our cybersecurity program.

Political Contribution Oversight

The Board oversees our political engagement policies, programs and practices. The Governance Committee is also responsible for advising and assisting the Board with respect to our political engagement. Our policies, including the governance and decision-making process for corporate political contributions, as well as biannual contribution reports, are described in detail at cmsenergy.com/corporate-governance/Political-Engagement/default.aspx. We believe Board oversight of our political activity along with the Board’s alignment with our current disclosure standards provide the necessary accountability to ensure that political activities are conducted in the best interest of customers, shareholders and other stakeholders. Through Board oversight, we have maintained a rigorous compliance process to ensure that our political activities are lawful, properly disclosed and align with our Codes.

Public Responsibility and Sustainability Oversight

We integrate multiple levels of sustainability oversight into our daily operations and use several governance and risk management tools when addressing governance, environmental, public responsibility and sustainability matters. These include oversight by the Board, an enterprise risk management program and robust strategic and business planning processes. The Board oversees our public responsibility and sustainability practices. The Governance Committee is also responsible for advising and assisting the Board with respect to our public responsibility, including stakeholder outreach, stewardship and corporate social responsibility and sustainability matters. We are committed to corporate social responsibility through our business, culture, environment and our communities – past, present and future. This aligns with our purpose, which is to provide safe, reliable, affordable, clean, and equitable energy in service of our customers. We measure our progress toward this purpose by considering our impact on the “triple bottom line” of people, planet and prosperity; this consideration takes into account not only the economic value that we create, but also our progress on our social and environmental goals.

The planet element of the triple bottom line represents our commitment to help protect the environment, which extends beyond complying with the various state and federal laws and regulations. We provide extensive public reporting and are forthcoming in disclosures about our environmental stewardship and long-term strategy. We address issues related to climate change in SEC, Environmental Protection Agency and other regulatory agency filings, and by voluntarily reporting our climate risk strategy and related data. We have published Sustainability Reports, a Climate Change, Risk, Vulnerability and Resiliency Report, and a Methane Reduction Plan. Consumers' 2021 Integrated Resource Plan, approved by the Michigan Public Service Commission, included plans to stop using coal as a fuel source for owned generation in 2025, but the retirement of our last coal plant is still subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy.

We intend to create a cleaner, more sustainable energy future by taking a leadership position in reducing air emissions and water usage, saving landfill space and boosting the amount of renewable energy supplied to customers. We update and enhance disclosures relating to our sustainability efforts and climate-related risks and opportunities. These disclosures and updates can be found on our website at cmsenergy.com/sustainability/default.aspx.

As part of our overall corporate governance, we have an ongoing outreach program to develop and maintain communication with our investors. We value these discussions and the Board considers pertinent investor feedback. In addition, management regularly participates in investor and industry conferences throughout the year to discuss performance and sustainability topics and share its perspective on business and industry developments. Shareholders may also contact the Board with any inquiry or issue, by the methods described below, and the Board will respond as appropriate.

Board Communication Process

Interested parties, including shareholders, employees or third parties can communicate with the Board, any Committee, the independent Directors as a group or an individual Director, including the Chairman or Presiding Director, by sending written communications to the Corporate Secretary, at the Corporation's principal business office, One Energy Plaza, Jackson, Michigan 49201. Envelopes should be clearly marked “Board Communication” or “Director Communication.”

The Corporate Secretary will review and forward, as appropriate, such correspondence in order to facilitate communications with the Board or its Committees, the independent Directors or individual members.

Any shareholder, employee or third party who wishes to submit a compliance concern to the Board or applicable Committees, including complaints regarding accounting, internal accounting controls or auditing matters to the Audit Committee, may do so by any of the following means:



Send correspondence or materials addressed to the appropriate party c/o the Chief Compliance Officer, CMS Energy Corporation or Consumers Energy Company, One Energy Plaza, Jackson, Michigan 49201	Send an email or other electronic communication via the external website https://cms.speakfullynow.com, addressed to the appropriate party	Call the CMS and Consumers Compliance Hotlines at either 1-517-788-6260 (an internally monitored line) or 1-888-440-8464 (monitored by an external vendor)

Identification of Director Candidates

The Governance Committee is responsible for Board succession planning, which includes identifying and evaluating Director candidates to serve on the Board consistent with the criteria approved by the Board, and recommending a slate of Director candidates for election at the Annual Meeting. The following diagram illustrates the steps in identifying Director candidates:

2026 Proxy - Directors Candidate Graphic- Canva.jpg

The Governance Committee will consider shareholder-recommended Director nominees in accordance with the requirements of our Bylaws. The information that must be included and the procedures that must be followed by a shareholder wishing to recommend a Director candidate for the Board's consideration are the same as would be required under our Bylaws if the shareholder wished to nominate that candidate directly. The Governance Committee will consider Director candidates recommended by shareholders on the same basis that the Governance Committee evaluates other nominees for Director.

CMS Bylaws also permit a shareholder, or a group of up to 20 shareholders, who have owned, continuously for at least three years, at least three percent of the outstanding shares of CMS common stock to submit Director nominees (not greater than two or 20% of the Board) for inclusion in its proxy statement if the shareholder(s) and the nominee(s) satisfy the requirements in the CMS Bylaws.

A Director nomination that is not submitted for inclusion in the proxy statement but instead is sought to be presented directly at the Annual Meeting must comply with the advance notice provisions in our Bylaws.

Any recommendation or nomination submitted by a shareholder regarding a Director candidate must be submitted within the time frame provided in our Bylaws for Director nominations and must include (a) a statement from the proposed nominee that he or she has consented to the submission of the recommendation or nomination and (b) such other information about the proposed nominee(s) and/or nominating shareholder(s) as is required by our Bylaws.

Written notice must be sent to the Corporate Secretary, One Energy Plaza, Jackson, Michigan 49201. You may access our Bylaws at cmsenergy.com/corporate-governance/our-view-on-governance/default.aspx.

Director Candidate Qualifications

Director candidates are sought whose particular background, experiences and qualities meet the needs of the Board. The Board values high standards of integrity, business ethics and sound judgment, which add value, perspective and expertise to the Board's deliberations. The Governance Committee assesses, on a regular basis, the qualifications needed by the Board in light of the Board's current composition and recommends changes to the Board when appropriate and determines from time-to-time other criteria for selection and retention of Board members. As stated in our Principles, we aim for the Board to represent a broad spectrum of diverse business, political, academic, demographic and social interests. The Governance Committee takes a wide range of factors into account in evaluating the suitability of Director candidates, including experience in business, leadership, regulated utility, sustainability and environment, risk management, customer experience, safety, governance, accounting, finance, legal, information technology, lean practices and compensation and human resources, which brings a diversity of thought, perspective, approach and opinion to the Board. The Governance Committee does not have a single method for identifying Director candidates but will consider candidates suggested by a wide range of sources.

In 2025, the Governance Committee retained a search firm (Heidrick & Struggles) to assist in the identification and assessment of potential Director candidates, which identified Keyes and Leopold as candidates for the Board.

Board Refreshment

The Board believes that a mix of tenure adds value, perspective and expertise to the Board's deliberations, with longer-tenured Directors bringing a deep understanding of the Corporation and shorter-tenured Directors bringing a fresh perspective. Since 2020, the Board has added four new Directors. Director term limits, included in our Principles, state that Directors (other than the CEO) first elected after January 2017 may not serve on the Board for more than 15 years and Committee chairs (other than the Executive Committee) may not serve in such role for more than five years.


CMS ENERGY 2026 PROXY STATEMENT			14

Director Independence

Directors Butler, Izzo, Keyes, Leopold, Russell, Shank, Soto, Sznewajs, Tanski, Wright are and former Director Kurt Darrow was deemed “independent” as determined by the Board, in accordance with the NYSE listing standards, applicable rules and regulations of the SEC, our more stringent Independence Standards, as set forth in our Principles, and taking into consideration all business relationships between the Corporation and its subsidiaries and each non-employee Director.

The following relationships were identified and deemed immaterial to such Directors' independence:

•charitable contributions made to organizations of which certain of the Directors are affiliated;

•purchases and sales of services, commodities, materials or equipment, to and from entities, during the ordinary course of business, with which certain of the Directors are affiliated and all such transactions were significantly below one percent of the consolidated gross revenues of the counterparty to the transaction; and

•retail electricity or natural gas purchases from Consumers at rates or charges fixed in conformity with law or governmental authority.

In addition, the Board has affirmatively determined that each member of the Audit Committee and Compensation Committee is independent under NYSE listing standards and the additional independence standards applicable to such committee service.

The Independence Standards, adopted by the Board as part of our Principles, can be found at cmsenergy.com/corporate-governance/our-view-on-governance/default.aspx.

Director Service on Other Public Company Boards

The Board recognizes that service on other public company boards provides valuable governance and leadership experience that benefits the Corporation. The Board also believes, however, that it is critical that Directors dedicate sufficient time to their service on the Corporation's Board. In view thereof, our Principles state that before joining another public company board, the Director must notify the Chairman, the chair of the Governance Committee and the Corporate Secretary. Furthermore, our Principles state that a non-employee Director may not serve on more than four other public company boards and the CEO may not serve on more than two other public company boards. All of our Directors meet these guidelines. In evaluating Director candidates, the Governance Committee also takes into account their time commitments, including things such as their principal occupation and service on other public or private boards. The Board has specifically determined that the ability of our Directors to serve on our Board and committees is not impaired by their service on other boards. Additionally, the Board has specifically determined that the ability of our Audit Committee members to serve on our Audit Committee is not impaired by service on other audit committees.

CMS Majority Voting Standard

Under the CMS Articles of Incorporation, CMS Bylaws and our Principles, any Director nominee who receives less than a majority of the votes cast by the CMS shareholders at a regular election shall promptly tender his or her resignation. For this purpose, a majority of the votes cast means that the number of shares voted “for” a Director must exceed 50% of the votes cast with respect to that Director, not counting abstentions. Upon receipt of such a tendered resignation, the CMS Governance Committee shall consider and recommend to the CMS Board whether or not to accept the resignation. The CMS Board will act on the CMS Governance Committee's recommendation and will cause CMS to publicly disclose the CMS Board's decision whether to accept or decline such Director's resignation offer (and the reasons for rejecting the resignation offer, if appropriate) within 90 days following certification of our shareholder vote. The Director who tenders his or her resignation pursuant to the standard will not be involved in either the CMS Governance Committee's recommendation or the CMS Board's decision to accept or decline the resignation. Due to complications that arise in the event of a contested election of Directors, this standard would not apply in that context, and instead a plurality vote standard would control any contested Director elections.

Director Education

At the Corporation's expense, Board members are expected to attend at least one continuing education program annually, sponsored by a recognized utility industry, corporate governance organization or an internal Director education program. The internal program includes corporate and industry information disseminated through orientation programs, presentations, business training modules and reports and operational site visits. This bespoke internal education program allows us to tailor programs to enhance our Board's ability to provide appropriate oversight. We offered one internal education program in 2025 - Industry Evolution in Safety, which was attended by all Directors.

Board, Committee and Director Evaluations

The Board is committed to continuous self-improvement, and Board and Committee evaluations are an important tool for promoting effectiveness. The Board conducts a performance evaluation annually and, at least once every three years, engages a third party to conduct individual Director peer evaluations.

Board and Committee evaluations are conducted for the Board and each standing Committee. Each Director participates in the process as illustrated below.


CMS ENERGY 2026 PROXY STATEMENT			15

Board, Committee and Director Eval Graphic.jpg

Our evaluation methodology also includes interviews of Directors and members of our executive leadership team who regularly interact with the Board and the Committees by an independent third-party facilitator to be conducted at least once every three years in order to solicit candid and actionable feedback. The robust multi-layered approach to our Board and Committee evaluation process is illustrated below.

Board, Committee and Director Eval Graphic 2.jpg


CMS ENERGY 2026 PROXY STATEMENT			16

The questionnaire assesses, among other items, Board: 1) effectiveness, including but not limited to, operations, oversight and future challenges; 2) processes; and 3) composition. Directors may choose to provide their feedback anonymously.

Director peer evaluations provide Directors an opportunity to evaluate each other and identify opportunities for their own growth and development. Peer evaluations and development follow-ups are facilitated by an independent third party and include confidential, open-ended, one-on-one interviews with each Director. The Board has conducted these periodic peer evaluations since 2008. The latest Director peer evaluation cycle began in 2024.

Board and Committee Information

The CMS and Consumers Board each met eight times during 2025. Our Principles state the expectation that each Director will attend all scheduled Board and Committee meetings of which he or she is a member, as well as the Corporation's annual meeting of shareholders. All Directors serving during 2025 attended more than 75% of the Board and assigned Committee meetings and all then-serving Board members attended the 2025 annual meeting of shareholders.

The Board has five standing Committees including an Audit Committee, a Compensation Committee, a Finance Committee, a Governance Committee and an Executive Committee. The members and the responsibilities of the standing Committees of the Boards are listed below.

Each Committee is composed entirely of “independent” Directors, as that term is defined by the NYSE listing standards and our Principles described above. Committees may also invite members of management or others to attend their meetings as they determine appropriate. Rochow routinely attends Committee meetings.

On a regularly-scheduled basis, the non-employee Directors meet in executive session (that is, with no employee Directors present) and may invite such members of management to attend as they determine appropriate. At least once each year, the independent Directors meet in executive session in conformance with the NYSE listing standards. In 2025, the CMS independent Directors met four times and the Consumers independent Directors met four times. In 2025, Chairman Russell presided over the executive sessions of independent Directors.

Codes of Ethics

We have adopted an employee code of ethics, titled “Code of Conduct and Guide to Ethical Business Behavior” (“Employees' Code”) that applies to the CEO, Chief Financial Officer (“CFO”) and Chief Accounting Officer (“CAO”), as well as all other officers and employees of CMS and Consumers. CMS and Consumers have also adopted a Director code of ethics titled “Board of Directors Code of Conduct and Guide to Ethical Business Behavior” (“Directors' Code”) that applies to the members of the Board. The Governance Committee annually reviews the Codes and recommends changes to the Board, as appropriate. The Employees' Code is administered by the Chief Compliance Officer, who reports directly to the Audit Committee. The Audit Committee oversees compliance with the Codes. Any alleged violation of the Directors' Code will be investigated by disinterested members of the Audit Committee, or if none, by disinterested members of the Board. The Governance Committee would recommend appropriate action to the Board in the event a determination is made that a Director violated the Directors' Code. The Codes and any waivers of, or amendments or exceptions to, a provision of the Employees' Code that applies to the CEO, CFO, CAO or persons performing similar functions and any waivers of, or exceptions to, a provision of our Directors' Code will be disclosed on our website at cmsenergy.com/corporate-governance/compliance-and-ethics/default.aspx.

Compensation Risk

Management annually undertakes a comprehensive review of the compensation policies and practices throughout the organization in order to assess the risks presented by such policies and practices. In 2025, the Compensation Committee engaged our independent compensation consultant to conduct a compensation risk review and assess the potential risks associated with executive compensation. This review included three perspectives:

•Plan design and administration risk,

•Say on Pay/proxy advisor/reputation risk, and

•Talent risk.

The compensation consultant assessed multiple individual key risk indicators which included items such as base salaries, incentives, performance goals, stock ownership requirements, CEO pay compared to other NEOs and retention elements. These risk indicators were all reviewed on a scale of low, medium and high risk. The compensation consultant found there were no areas of high risk and reviewed its analysis with the Compensation Committee. Through this process, it was determined that our compensation policies and practices are not reasonably likely to have a material adverse effect on CMS or Consumers.

No Illegal Insider Trading, Pledging or Hedging

Our Policy Prohibiting Illegal Insider Trading and Codes, among other things, prohibit CMS’ and Consumers’ Directors and officers from engaging in illegal insider trading as well as pledging or purchasing the Company securities on margin, “trading” of our securities or selling “short” our securities or buying or selling puts or calls or hedges relating to our securities, including compensatory awards of equity securities or our securities otherwise held, directly or indirectly, by those persons. For purposes of this policy and the Codes, “trading” means a combination or pattern of substantial or continuous buying and selling of securities with the primary objective of realizing short-term gains. Selling “short” is a technique in which investors bet on a stock price falling by selling securities they do not own with the understanding that they will buy them back, hopefully at a lower price. A copy of our Policy Prohibiting Illegal Insider Trading was filed as Exhibit 19.1 to our annual report on Form 10-K for the year ended December 31, 2024.

Related Party Transactions

CMS, Consumers or their subsidiaries may occasionally enter into transactions with Related Parties. “Related Parties” include Directors or executive officers, beneficial owners of more than 5% of our common stock, family members of such persons, and entities in which such persons have a direct or indirect material interest. As set forth in our Codes, we consider a related party transaction to have occurred when a Related Party enters into a transaction in which we are participating, the transaction amount is more than $10,000 and the Related Party has or will have a direct or indirect material interest (“Related Party Transaction”). Any Related Party Transaction must be reported to us.

In accordance with our Codes and the Audit Committee Charter, Related Party Transactions must be pre-approved by the Audit Committee. In drawing its conclusion on any approval request, the Audit Committee considers the following factors:

•whether the transaction involves the provision of goods or services that are available from unaffiliated third parties;

•whether the terms of the proposed transaction are at least as favorable as those that might be achieved with an unaffiliated third party;

•the size of the transaction and the amount of consideration payable to a Related Party;

•the nature of the interest of the applicable Related Party; and

•whether the transaction may involve an actual or apparent conflict of interest, or embarrassment or potential embarrassment when disclosed.


CMS ENERGY 2026 PROXY STATEMENT			19

The policies and procedures relating to the Audit Committee's approval of Related Party Transactions are found in the Codes, which are available at cmsenergy.com/corporate-governance/compliance-and-ethics/default.aspx, and do not apply to management contracts or compensation plans as approved under separate policies.

Angela Thompkins, a sister to Tonya Berry, an executive officer, is employed by the Corporation in a non-executive officer position and received compensation approved by the Compensation Committee in accordance with its compensation practices described in our Compensation Discussion and Analysis. Leslie Youngdahl, a sister, and Clay McAndrews, a brother-in-law to Lauren Snyder, an executive officer, are employed by the Corporation in non-officer positions and received compensation in accordance with compensation practices outlined in our internal employee handbook.

Management Succession Planning

The Board engages in an active succession planning process. The Board selects a CEO and then consults with the CEO concerning the selection of a senior management team and plans for their succession. The management succession plan also includes provisions for the CEO. The Compensation Committee advises the Board on succession planning, including policies and principles for executive officer selection. CEO evaluations are conducted annually.

Narrative to 2025 Directors' Compensation Table

Non-employee Director compensation is benchmarked annually. Non-employee Directors receive an annual retainer fee and restricted stock award for service on the CMS and Consumers Boards and additional annual retainer fees for certain Committee positions. Rochow, the only employee Director, does not receive Director compensation. Directors are reimbursed for expenses incurred in attending Board or Committee meetings and other company business.

The following table describes the annual cash retainer fee and other fees received for Director service in 2024 and 2025. The cash fees for the 1) chair of the Audit Committee 2) remaining members of the Audit Committee and 3) presiding director were all increased in 2025 to align the Director compensation program with market practice. The 2026 Director compensation program will not change as compared to the 2025 Director compensation program. Annual retainer fees are paid based on the number of months served on the Board in each respective capacity.


Year	Annual Cash Retainer	Chairman of the Board	Presiding Director	Chair of the Audit Committee	Other Members of the Audit Committee	Chair of the Compensation Committee	Chairs of the Finance and Governance Committees
2024	$115,000	$175,000	$30,000	$22,500	$5,000	$20,000	$20,000
2025	$115,000	$175,000	$35,000	$25,000	$10,000	$20,000	$20,000

In May 2025, non-employee Directors were awarded a number of shares of restricted stock with a fair market value at the time of award of $175,000. These shares of restricted stock are 100% tenure-based and vest 100% at the next annual meeting date. Under our Performance Incentive Stock Plan in effect at the time of grant, non-employee Directors may defer receipt of their annual equity awards until a deferral date selected by the Director. If a deferral election is made by the Director, the equity awards subject to the deferral election will be granted as restricted stock units rather than restricted stock awards. Directors Butler, Izzo, Shank, Soto, and Sznewajs elected to defer their 2025 equity grants.

Stock ownership guidelines have been adopted by the Board that further align the interests of the Directors with our shareholders. Non-employee Directors are required to hold CMS common stock equivalent in value to five times their annual cash retainer by the end of the fifth calendar year of becoming a Director. In the event a Director has not met the stock ownership guidelines in the prescribed time frame, in lieu of the Director receiving his or her monthly cash retainer, the retainer will be used to purchase shares of CMS common stock until such time as the guideline has been met. All Directors currently comply with this stock ownership requirement or are currently expected to comply by the end of their fifth calendar year of becoming a Director.

Pursuant to the Directors' Deferred Compensation Plan (“DCP”), a non-employee Director may, at any time prior to the calendar year in which cash retainer fees are to be earned, irrevocably elect to defer payment, through written notice to the Corporation, all or a portion of any of the cash retainer fees that would otherwise be paid to the Director. Deferred amounts will be distributed in a lump sum or in annual installments in cash, as specified in the Director's initial election. Fidelity Investments, an independent record keeper, administers the DCP. The participant decides how contributions are invested among a broad array of mutual funds selected and provided by the record keeper. Funds equal to the amounts deferred are transferred to Fidelity Investments. Our payment obligations to the Directors remain an unsecured contractual right to a payment. Directors Butler, Izzo, Shank, Soto, and Tanski elected to defer receipt of their 2025 fees under the DCP.

Best Practices

We annually review all elements of the Corporation's executive compensation program and, in addition to designing a program to comply with required rules, we adopt current best practices when deemed appropriate for our business and shareholders. As a result,

We have …

•a majority of pay in variable elements;

•a majority of variable pay in long-term incentive ("LTI") awards;

•a majority of LTI delivered in performance-based restricted stock;

•all LTI denominated and settled in equity;

•LTI payouts capped at target if three-year absolute total shareholder return performance is not positive;


CMS ENERGY 2026 PROXY STATEMENT			24

•a balance of absolute and relative metrics used in annual incentives and LTI;

•stock ownership guidelines for NEOs, which exclude stock options and unvested performance-based restricted stock awards when determining compliance;

•change-in-control agreements that require a double-trigger for the accelerated vesting of equity awards;

•a policy that prohibits hedging and pledging of the Corporation’s securities by officers;

•annual reviews of risk within our incentive programs;

•annual reviews of our Compensation Peer Group and Performance Peer Group; and

•regular briefings from the Compensation Committee's independent compensation consultant regarding key trends and legislative and regulatory updates.

We do not have …

•excessive perquisites - no planes, cars, clubs or financial planning, with an annual physical examination being the principal perquisite provided to our executives in 2025;

•dividends paid on unvested performance-based restricted stock awards - in lieu of dividends, recipients receive additional shares of restricted stock that are contingent on the same performance measures and forfeiture conditions applicable to the underlying restricted stock;

•employment agreements - our executive agreements are limited to separation and change-in-control agreements, with base salary and annual incentive separation amounts not exceeding three times the NEO's base salary and annual incentive amount, with an average of two times; and

•tax gross-ups - none of our separation or change-in-control agreements contain tax gross-ups.

Shareholder's Advisory Vote to Approve Executive Compensation

As part of the Compensation Committee's on-going review of executive compensation, we considered the affirmative 2025 CMS shareholder advisory vote to approve executive compensation as described in last year's Proxy Statement and determined that the current philosophy, objectives and compensation elements continue to be appropriate. The CMS advisory vote to approve executive compensation, as described in the 2025 CMS Proxy Statement, resulted in a high level of shareholder support with approximately 93% of votes cast in favor of the proposal. We considered this strong shareholder approval in continuing to employ the same performance-oriented program design during 2025. As such, the Compensation Committee did not make any changes to our executive compensation programs in response to the 2025 CMS shareholder vote. Despite the high level of shareholder support, we continue to monitor best practices and emerging trends and engage with our large institutional holders regarding compensation elements. The remainder of this Compensation Discussion and Analysis offers a detailed explanation of the 2025 NEO compensation program.

Objectives of Our Executive Compensation Program

The Compensation Committee is responsible for approving the compensation program for the NEOs. The Compensation Committee acts pursuant to its Charter that is annually reviewed by the Board and is available on our website.

The NEO compensation program is organized around four principles:

•Align With Increasing Shareholder and Customer Value;

•Enable Us to Compete for and Secure Top Executive Talent;

•Reward Measurable Results; and

•Be Fair and Competitive.

Align With Increasing Shareholder and Customer Value

We believe that a substantial portion of total compensation should be delivered in the form of at-risk equity in order to further align the interests of the NEOs with the interests of our shareholders and customers. Equity compensation granted in 2025 to our NEOs was provided through the Performance Incentive Stock Plan (“Stock Plan”). In 2025, awards were subject to the achievement of three-year relative TSR performance and three-year relative LTI EPS growth goals, each weighted equally, over a three-year performance period from January 1, 2025 to December 31, 2027.

Assuming target performance, the following charts illustrate the pay mix for the CEO and the average pay mix for the other NEOs as of December 31, 2025.


CMS ENERGY 2026 PROXY STATEMENT			25

Program Design

We have designed our executive compensation elements to be balanced and simple, placing emphasis on consistent, sustainable and superior absolute and relative performance. The following elements deliver our executive total direct compensation: base salary, annual incentive and long-term incentive.

BASE SALARY. Base salary is targeted to approximate the median of our Compensation Peer Group which is made up of companies of similar business profile and size, with adjustments to reflect individual performance and internal considerations.

ANNUAL INCENTIVE. 2025 annual incentive awards are based on the achievement of Annual Incentive EPS (70% of annual incentive) and Annual Incentive Utility (30% of annual incentive) goals. For more information, see The Elements of Our Executive Compensation Program, Cash Compensation and Plan Performance Factor below.

We pay an annual incentive only if the results meet or exceed the threshold performance levels approved by the Compensation Committee by the end of January of each year. In 2025, Annual Incentive EPS was used to determine the financial annual incentive payout while Annual Incentive Utility, a measure of our operational success on metrics relating to people, planet, and prosperity, was used to determine the operational annual incentive payout. The Compensation Committee viewed success on these metrics as the building blocks for growing the value of the Corporation and as good indicators of how well we are executing our customer-focused strategy. We place more weight on Annual Incentive EPS to reflect the Corporation's and shareholders' focus on EPS growth and to align our performance objectives and incentive allocation with our Compensation Peer Group practices and our utility-focused strategy. The 2025 Annual Incentive Utility goals are the same operating metrics under the Consumers' Annual Employee Incentive Compensation Plan (“Consumers Incentive Plan”). The Compensation Committee included the Annual Incentive Utility metric in the 2025 annual incentive plan because the Compensation Committee believes that this alignment with operational performance and the broader utility employee population is an important aspect of our program design.

The six operating goals under the Annual Incentive Utility metric are focused on people, planet and prosperity to further emphasize our commitment to our strategy and represent sustainability items considered material to our strategy. See The Elements of Our Executive Compensation Program below for additional details on the operational targets.

LONG-TERM INCENTIVE. The LTI program consists of performance-based restricted stock (75% of total target LTI) and tenure-based restricted stock (25% of total target LTI).

The 2025 performance-based portion is eligible to vest after three years dependent upon our TSR performance and LTI EPS growth (each weighted equally) relative to the Performance Peer Group. The 2025 LTI program is distinct from the annual incentive plan in that it focuses on relative multi-year performance rather than absolute one-year performance. The tenure-based portion vests on the third anniversary of the award date.


CMS ENERGY 2026 PROXY STATEMENT			26

Our 2025 LTI program is based on relative TSR performance and relative LTI EPS growth because the Compensation Committee believes that these measures offer a head-to-head comparison of how well our management team performed compared to other management teams in our industry and further motivate management to increase shareholder and customer value through stock price and earnings growth.

We tie a portion of equity compensation to vesting based on continued employment. The tenure-based restricted stock helps build executive share ownership and alignment with shareholders while serving as an additional retention mechanism that is not subject to the year-to-year fluctuations of any performance measurement, although the value is subject to the performance of our stock price.

In 2025, the performance-based restricted stock awards granted in 2023 completed the three-year performance period, with the post-performance period tenure-based vesting satisfied in early 2025. The 2023 performance-based restricted stock awards vested based upon the relative TSR and LTI EPS growth performance during the performance period (January 1, 2023 to December 31, 2025). Our TSR for the three-year performance period (January 1, 2023 to December 31, 2025) was 22% while the median TSR for our Performance Peer Group was 21%, placing CMS, by comparison, in the 52nd percentile. Our LTI EPS growth for the three-year performance period (January 1, 2023 to December 31, 2025) relative to the Performance Peer Group is not expected to be known until after March 26, 2026.

Enable Us to Compete for and Secure Top Executive Talent

Shareholders and customers are best served when we can attract, retain and motivate talented executives. We create a compensation package for NEOs that delivers total compensation generally targeted to approximate the 50th percentile of the market. The Compensation Peer Group consists of publicly traded utility companies deemed comparable in business focus and size to CMS with which we might compete for executive talent. The Compensation Committee also reviews size-adjusted public utility sector and general industry data, where comparable positions are identifiable.

Annually, the Compensation Committee engages a consultant to provide advice and information regarding compensation practices of the Compensation Peer Group as well as additional information from published surveys of compensation practices in the public utility sector and general industry.

During the Compensation Committee's review of the CEO's and other officers' compensation levels, the Compensation Committee considered the advice and information received from Pay Governance LLC (“Pay Governance”), the Compensation Committee's independent compensation consultant; however, the Compensation Committee was ultimately responsible for determining the form and amount of executive compensation. During the time that Pay Governance has been engaged as the compensation consultant, Pay Governance has not performed any services on behalf of management or otherwise been considered to have a conflict of interest regarding CMS or Consumers. The Compensation Committee must direct and approve any work Pay Governance may undertake on behalf of management.

Reward Measurable Results

Base salary is reviewed annually and may be adjusted based on a variety of factors, including each NEO's overall performance (both individual and functional) and tenure. The CEO recommends annual base salary adjustments, annual incentive targets and annual restricted stock awards for all officers, other than the CEO. When making adjustments, the Compensation Committee considers the CEO's recommendations, along with Compensation Peer Group data, internal equity, tenure and other market data from surveys provided by the independent compensation consultant. CEO base salary is determined solely by the Compensation Committee based on, among other factors, Compensation Peer Group data, other market data and overall Corporation and CEO performance.

Annual incentives, the other form of cash compensation, provide for award opportunities to each NEO under the Annual Incentive Plan. The Annual Incentive Plan pays incentives on the basis of performance during a one-year performance period. Performance objectives under the Annual Incentive Plan are finalized at the start of each year through an iterative process. Management, including executive officers, develops preliminary recommendations for the Compensation Committee's review and approval. For 2025, the Annual Incentive Plan targeted awards varied from 65% to 125% of each NEO's base salary, but payouts could range from zero to 200% of that target level depending on performance against specific corporate performance goals.

For 2025, 75% of the equity compensation granted to the NEOs was performance-based, designed to reward measurable results. Vesting of such awards is subject to the achievement of relative TSR performance and relative LTI EPS growth goals, weighted equally, over a three-year performance period of January 1, 2025 to December 31, 2027.

The table below illustrates the manner in which: (a) the overall mix of target total direct compensation was allocated between variable at-risk and fixed elements for each NEO; (b) variable at-risk compensation was allocated between annual and long-term incentives; and (c) target total direct compensation was allocated between cash and equity. Variable at-risk pay is generated from shareholder funds and is not included in the rates of Consumers' electric and gas customers.

Be Fair and Competitive

We strive to create a compensation program that is fair and competitive, both internally and externally. This is accomplished by evaluating each NEO's individual performance and by comparing the NEOs' compensation to:

•officers of the Compensation Peer Group (as well as other market data as described above) as a means to measure external competitiveness; and

•other senior employees of CMS as a means to assess internal fairness.

USE OF TALLY SHEETS. At least annually, the Compensation Committee reviews tally sheets for each of the NEOs. These tally sheets reflect all components of compensation, including base salary, annual incentives and LTI compensation, retirement benefits, deferred compensation benefits, death benefits and benefits or payments that would be payable in connection with a termination of employment or change-in-control. Tally sheets are provided to the Compensation Committee to show how various compensation and benefit amounts are interrelated and how a change in one component of compensation impacts other components and to enable the Compensation Committee to quantify amounts payable upon various termination scenarios.

The overall purpose of these tally sheets is to consolidate all elements of actual and potential future compensation of the NEOs, as well as information about wealth accumulation. Using tally sheets, an analysis can be made of both the individual elements of compensation (including the compensation mix) and the aggregate total amount of actual and projected compensation. Tally sheet information is used in various aspects of the analysis and compensation decision-making process, including consideration of our management team's internal pay equity.

Competitive Data

The Compensation Peer Group data, where available by position, serve as the primary reference point for pay comparisons of utility-specific roles. Broader survey data and published proxy data are also provided by the compensation consultant as a point of reference for utility specific roles and comparisons of general industry roles (primarily for staff positions). Where available by position, Pay Governance also gathers compensation data from Willis Towers Watson's Energy Services Executive Database (which includes participating investor-owned utilities) and Willis Towers Watson's General Industry Executive


CMS ENERGY 2026 PROXY STATEMENT			28

Database (which includes more than 500 participating companies), which it size-adjusts based on CMS' revenues to provide additional market context to the Compensation Peer Group. In selecting members of the Compensation Peer Group, financial and operational characteristics are considered by the Compensation Committee. The criteria for selection of the Compensation Peer Group for 2025 included comparable revenue (with 2024 revenues ranging from approximately .34x to 2.09x CMS), relevant industry characteristics, business mix (revenue mix between regulated and non-regulated operations) and availability of compensation and financial performance data.

The 2025 Compensation Peer Group is composed of the companies set forth below. The 2025 Compensation Peer Group is unchanged from the Compensation Peer Group used to evaluate 2024 compensation decisions, with the exception of the addition of Evergy, Inc. The addition of Evergy, Inc. aligns with the financial and business criteria outlined above. Adding Evergy, Inc. to the 2025 Compensation Peer Group increased the sample size of the peer group to 19 and better positioned CMS closer to the median of the peer group in regards to revenue and market cap.

The Compensation Committee recognizes that there is a difference between the companies against which we compete for executive talent (“Compensation Peer Group”) and the companies against which we compete for capital (“Performance Peer Group”) and, therefore, uses different peer groups for these two different purposes. For this reason, the Compensation Committee approved the use of the Compensation Peer Group shown above for evaluating 2025 NEO compensation decisions and a larger peer group, the Performance Peer Group shown below, for measuring relative TSR performance and EPS growth. The Compensation Committee’s rationale for using two peer groups is to provide appropriate comparative companies relative to the different attributes being evaluated for compensation and relative performance purposes. In addition, the larger Performance Peer Group considered by the Compensation Committee was intended to provide for better gradation of resulting performance position than the Compensation Peer Group could have, given its size.

For awards made in 2025, the Performance Peer Group was composed of the publicly traded utilities included in the S&P 500 and S&P Midcap 400 indexes. If a Performance Peer Group company is no longer trading as of the LTI vesting date, it is excluded from the LTI performance calculation. As of the 2025 LTI grant dates, the Performance Peer Group consisted of the following companies:

The Elements of Our Executive Compensation Program

This section describes the various elements of our compensation program for NEOs, together with a discussion of various matters relating to those items, including why we chose to include the items in the compensation program.

Cash Compensation

Cash compensation is paid in the form of base salary and annual incentive. Our 2025 compensation program for NEOs was designed so that the percentage of target cash compensation for the NEOs is comparable to the median of the Compensation Peer Group. That strategy resulted in cash-based compensation (as a percentage of target total direct


CMS ENERGY 2026 PROXY STATEMENT			29

compensation) representing approximately 30% for the CEO and 42% to 55% for the other NEOs. The components making up the cash portion of total direct compensation are described in more detail below.

BASE SALARY. Base salary is included in the NEO's annual compensation package because we believe it is appropriate that some portion of NEO compensation be provided in a form that is fixed and liquid. Base salary is also universally offered by the Compensation Peer Group. Each January, the Compensation Committee determines the base salary for each then-serving NEO. In addition, base salaries may be adjusted during the year to reflect changes in job responsibilities or promotions. Changes in base salary year-over-year are dependent on a comparison to market data, past performance and expected future contributions of each individual. The annual increases in base salaries for NEOs between 2024 and 2025 were as follows:


	2024 Base Salary (1)	2025 Base Salary (1)	Percentage Increase (2)
Garrick J. Rochow	$1,250,000	$1,275,000	2.0%
Rejji P. Hayes	$810,000	$885,000	9.3%
Tonya L. Berry	$420,000	$635,000	51.2% (3)
Shaun M. Johnson	$620,000	$700,000	12.9% (3)
Brandon J. Hofmeister	$545,000	$600,000	10.1% (4)
LeeRoy Wells Jr.	$575,000	$585,000	1.7%

(1)Represents annual base salary level, in effect on December 31st of each year.

(2)Annual increases are generally due to annual merit increases and market adjustments. When making merit increases and market adjustments for 2025, the Compensation Committee considered internal pay equity, tenure, market data from the Compensation Committee's independent compensation consultant and individual performance.

(3)This increase in base salary was approved in connection with Berry's promotion to the position of Executive Vice President and COO and Johnson's promotion to the position of Executive Vice President, Business Transformation, Chief Legal & Administrative Officer, effective as of July 1, 2025, and reflected market adjustments to bring each NEO closer to the market median for their new role.

(4)This base salary increase for Hofmeister was due to an annual merit increase and market adjustments to bring Hofmeister closer to the market median, effective January 1, 2025.

ANNUAL INCENTIVE. We use performance-based cash incentives as an element of compensation because they enable us to provide an incentive to the NEOs to accomplish specific performance priorities for CMS and provide additional cash compensation only if performance goals approved by the Compensation Committee are achieved. Generally, the threshold, target and maximum performance goals are set so that the difficulty in achieving a payout is consistent from year to year. For 2025, the Annual Incentive Plan was based on our success in achieving established earnings per share and utility operating goals described further below. The earnings per share performance goals are set at levels reflecting our budgeted performance and targeted growth and are based on historical and forecasted financial performance and analysis of peer performance goal guidelines.

The operational utility measures are set based on the strategic priorities to serve our customers and stakeholders. The target goals for each measure are set to provide a balance between areas where significant improvement is needed and where continuous improvement is required to provide safe, reliable and affordable service while strategically positioning us for sustainable operation. Operational targets are approved annually by the Compensation Committee in November for the following performance year.

The Annual Incentive Plan allows the Compensation Committee to exercise discretion to reduce or eliminate payouts and to increase payouts, up to 20%, when deemed warranted by the Compensation Committee.

Incentive payout ranges under the Annual Incentive Plan were approved in January 2025 by the Compensation Committee. In determining the payout ranges of incentives, the following factors were considered:

•the threshold, target and maximum incentive levels and incentives paid in recent years;

•the relative importance, in any given year, of each performance goal established pursuant to the Annual Incentive Plan; and

•the advice of the compensation consultant as to compensation practices at other companies in the Compensation Peer Group and within the utility industry.

Payments under the Annual Incentive Plan EPS goal can range, on the basis of performance, from 17.5% (threshold) to 200% (maximum) of the target incentive or may not occur if threshold criteria are not satisfied. Payments under the Annual Incentive Utility goal can range, on the basis of performance from 0.8% (threshold) to 175% (maximum).


CMS ENERGY 2026 PROXY STATEMENT			30

ANNUAL AWARD FORMULA. Annual awards for each eligible officer are based upon a Target Award Percentage of the officer's base salary for the performance year and are calculated and made as follows:

Individual Award = Base Salary X Target Award Percentage X Plan Performance Factor.

The Target Award Percentages for officers are determined annually by the Compensation Committee as discussed above. Target Award Percentages of base salary for NEOs in 2025 remained unchanged from the Target Award Percentages of base salary for NEOs in 2024, unless otherwise noted below. Target Award Percentages for 2025 were as follows:


Garrick J. Rochow			125%
Rejji P. Hayes			80%
Tonya L. Berry (1)			75%
Shaun M. Johnson (2)			80%
Brandon J. Hofmeister			65%
LeeRoy Wells Jr.			75%

(1) Target Award Percentage increased from 55% in 2024 to 75% in 2025, in connection with Berry's promotion to the position of Executive Vice President and COO, effective July 1, 2025.

(2) Target Award Percentage increased from 75% in 2024 to 80% in 2025, in connection with Johnson's promotion to the position of Executive Vice President, Business Transformation, Chief Legal & Administrative Officer, effective as of July 1, 2025.

PLAN PERFORMANCE FACTOR. We refer to Annual Incentive EPS and Annual Incentive Utility performance under the Annual Incentive Plan as the “Plan Performance Factor.”

For 2025, Annual Incentive EPS performance constituted 70% of the Plan Performance Factor and Annual Incentive Utility performance constituted the remaining 30% of the Plan Performance Factor. The Compensation Committee believes that the allocation between financial earnings per share and utility operational performance aligns our performance objectives with the Compensation Peer Group and our utility-focused strategy. The Annual Incentive EPS and Annual Incentive Utility metrics are deemed by the Compensation Committee to be key measures of CMS' financial and operational success and are used to measure and assess performance.

Under the Annual Incentive Plan, Annual Incentive EPS (CMS Adjusted (non-GAAP) EPS) is determined in accordance with GAAP, adjusted to exclude the following, if applicable:

•gains or losses on asset sales which have been excluded from adjusted EPS or are greater than or equal to 2% of adjusted EPS;

•changes in accounting principles resulting from new or revised accounting standards not included in the budget;

•large restructuring and severance expenses greater than $5 million or equal to $0.01 of EPS;

•3rd party costs related to the business optimization initiative, and SAP S/4 Implementation project (greater or equal to $0.01 of EPS);

•legal and settlement costs or gains related to previously sold assets;

•regulatory recovery for prior year changes;

•changes in federal and state tax law (including legacy and Inflation Reduction Act); and

•unrealized gains or losses, recognized in net income, from mark-to-market adjustments related to NorthStar Clean Energy's interest expense.

These adjustments relate to unusual events affecting CMS or its financial statements and were not deemed reflective of our day-to-day operational results.

Plan Performance Results

The following is the payout table for the Annual Incentive EPS goal for 2025.


	Payout Range	Target (1)	Actual (GAAP) Results	Annual Incentive Results	Payout Achievement (%)

Total Payout						129%

Equity Compensation

We have generally followed a practice of granting all equity awards to our officers on a single date each year. We do not have any program, plan or practice to time annual equity awards to our executives in coordination with the release of material non-public information. In 2025 and consistent with prior years, annual equity awards were made to the NEOs in January and are planned to be made in January on an on-going basis. This enables the Compensation Committee to review total compensation holistically at one time and adjust the levels of various compensation elements and compensation mix deemed as necessary for each individual.

STOCK PLAN. As previously indicated, we provide a substantial portion of NEO compensation in the form of equity awards because we believe that such awards serve to align the interests of NEOs with our shareholders and customers. Equity awards to the NEOs are made pursuant to our Stock Plan. The Stock Plan permits awards in the form of stock options, stock appreciation rights, restricted stock, restricted stock units, phantom shares and performance units. The minimum vesting period under the Stock Plan is 36 months for restricted stock, stock options and stock appreciation rights, subject to earlier vesting for a qualifying termination of employment. No dividends are paid on unvested performance-based stock awards. In lieu of dividends, recipients receive additional shares of restricted stock that vest based on the same performance measures and vesting conditions applicable to the underlying restricted stock.

AWARD OF PERFORMANCE-BASED RESTRICTED STOCK. At the present time, we believe that performance-based restricted stock (also known as performance shares) is an effective form of equity compensation because of the alignment it is intended to create with shareholders. After the vesting, there is no holding period requirement as long as specific stock


CMS ENERGY 2026 PROXY STATEMENT			32

ownership guidelines have been met by the NEO; see Corporate Governance as it Relates to Executive Compensation, Stock Ownership Guidelines, below. The Stock Plan also contains a clawback provision; see Corporate Governance as it Relates to Executive Compensation, Clawback Provisions, below.

Three-quarters of the restricted stock awards are performance-based and one-quarter is tenure-based in order to link a significant portion of each NEO's compensation to the long-term performance of the Corporation. The performance criteria for the performance-based restricted stock awards are a comparison of relative TSR performance and EPS growth relative to the Performance Peer Group, each weighted equally, utilizing the following performance schedule:

Achievement Level

Peer Group

Award Level

Minimum

30th Percentile

50%

Target

Median

100%

70th Percentile

150%

Maximum

90th Percentile

200%

The 20-day stock price averages preceding and including the award date and preceding and including the three-year anniversary of the award date are used to determine the relative TSR performance. The EPS growth is determined over the three-year performance period beginning with the start of the fiscal year of the grant and ending at the close of the third fiscal year. The 2025 tenure-based awards vest if the NEO remains employed by the Corporation on the three-year anniversary of the date of the award, subject to prorated vesting upon an earlier retirement or termination due to disability. Shares are sold at the time of vesting to cover tax withholdings.

PLAN PERFORMANCE FACTOR. Under the LTI, CMS Adjusted (non-GAAP) Earnings Per Share (“LTI EPS”) is determined in accordance with GAAP, adjusted to exclude the following, if applicable:

•gains or losses on asset sales which have been excluded from adjusted EPS or are greater than or equal to 2% of adjusted EPS;

•changes in accounting principles resulting from new or revised accounting standards not included in the budget;

•large restructuring and severance expenses greater than $5 million or equal to $0.01 of EPS;

•3rd party costs related to the business optimization initiative, and SAP S/4 Implementation project (greater or equal to $0.01 of EPS);

•legal and settlement costs or gains related to previously sold assets;

•regulatory recovery for prior year changes;

•changes in federal and state tax law (including legacy and Inflation Reduction Act); and

•unrealized gains or losses, recognized in net income, from mark-to-market adjustments related to NorthStar Clean Energy Company's interest expense.

CAP ON PAYOUT. If absolute TSR performance or LTI EPS growth is negative for the three-year performance period, the total payout for the three-year performance period cannot exceed 100% of the target award based on relative TSR performance or LTI EPS growth as compared to the Performance Peer Group.

RELATIVE TO PERFORMANCE RESULTS. In 2025, the performance-based restricted stock awards granted in 2022 completed the three-year performance period (January 2022 to December 2024) and service requirements. The 2022 performance-based restricted stock awards vested based upon our relative TSR and LTI EPS growth performance. Our TSR for the three-year performance period was 15% while the median TSR for our Performance Peer Group was 13%, placing CMS, by comparison, at the 52nd percentile. Our LTI EPS growth for the three-year performance period was 26% while the median EPS growth for our Performance Peer Group was 13%, placing CMS, by comparison, at the 79th percentile. This resulted in performance-based restricted stock awards vesting at 105.3% for TSR and 173.4% for LTI EPS growth.

In 2026, the performance-based restricted stock awards granted in 2023 completed the three-year performance period (January 2023 to December 2025) and service requirements. The 2023 performance-based restricted stock awards vested based upon our relative TSR and EPS growth performance. Our TSR for the three-year performance period was 22% while the median TSR for our Performance Peer Group was 21%, placing CMS, by comparison, in the 52nd percentile, resulting in a vesting level of 105.8% of target. Our EPS growth for the three-year performance period was 24%. Our EPS growth for the three-year performance period (January 1, 2023 to December 31, 2025) relative to the Performance Peer Group is not expected to be known until after March 26, 2026.

In determining the amount of equity compensation that is provided to each NEO in a given year, we consider factors such as retention and incentive practices, the relative percentages of cash and equity paid by the Compensation Peer Group and other market data. Based on these factors, the CEO recommends to the Compensation Committee restricted stock awards


CMS ENERGY 2026 PROXY STATEMENT			33

for the NEOs, other than the CEO. The Compensation Committee reviews and approves or modifies the equity grants to the other NEOs. CEO restricted stock awards are determined by the Compensation Committee based principally on overall CEO performance and Compensation Peer Group data.

OPTION GRANTING PRACTICES. There have been no stock option grants since August 2003 and there are no outstanding options. The Compensation Committee periodically considers the use of stock options as part of the current compensation package for officers but has determined not to include stock options for LTI at this time. If a stock option were to be granted, the Stock Plan prohibits:

•re-pricing of stock options by reducing the exercise price;

•buy-backs; and

•cancellation of previously granted stock options and subsequent re-grant at a lower exercise price than the canceled stock option.

Perquisites

As part of our competitive compensation plan, the NEOs are eligible for limited perquisites provided by or paid for by us, which include an annual executive physical examination, security and technology services and relocation expenses. .

The annual physical examinations for all NEOs are at a facility of our choosing and at our expense. The Compensation Committee believes that it is an effective method of protecting the NEOs and us from preventable health-related disruptions. Perquisites provided to the NEOs are reviewed on a regular basis.

Post-Termination Compensation

SEVERANCE AND CHANGE-IN-CONTROL BENEFITS. All active NEOs are eligible to receive severance payments and other benefits if the officer's employment terminates for a qualifying event or circumstance as well as change-in-control benefits upon a qualifying event or circumstance after there has been a change-in-control of CMS. For additional information regarding severance and change-in-control benefits, including a definition of key terms and a quantification of benefits that would have been received by the NEOs had a qualifying termination or change-in-control occurred on December 31, 2025, see Potential Payments upon Termination or Change-in-Control, below.

We believe that these severance and change-in-control arrangements are an important part of our executive compensation program and will help to secure the continued employment and dedication of the NEOs, notwithstanding any concern they may have regarding their own continued employment, prior to or following a change-in-control. These agreements are useful for recruitment and retention as nearly all members of the Compensation Peer Group have comparable terms and conditions in place for their senior employees.

Deferred Compensation Plans

We have two deferred compensation plans that allow certain employees, including the NEOs, to defer receipt of base salary and/or incentive payments: Deferred Salary Savings Plan (“DSSP”) and the Annual Incentive Plan. The Annual Incentive Plan allows for deferral of up to 100% of the annual incentive award. CMS does not match incentive amounts that are deferred pursuant to the Annual Incentive Plan. Participants have only an unsecured contractual commitment from us to pay the amounts due under both the DSSP and the Annual Incentive Plan. For additional information regarding the DSSP, see DSSP, under Narrative to 2025 Nonqualified Deferred Compensation Table, below.

We offer these plans to be competitive with market practice and to permit highly taxed employees to defer the obligation, at their discretion, to pay taxes on certain elements of compensation that they are entitled to receive. The provisions of the DSSP and the Annual Incentive Plan permit them to do this while also receiving investment returns on deferred amounts. We believe these benefits are useful as retention and recruitment tools as many of the Compensation Peer Group companies provide similar plans to their senior employees.

Tax Qualified Retirement Plans

The Corporation sponsors tax-qualified retirement savings plans that cover a broad group of employees.

Cash Balance Plan

An interim Cash Balance Plan was in effect for salaried employees hired between July 1, 2003 and August 31, 2005. The Cash Balance Plan is a funded, tax-qualified, noncontributory defined-benefit plan. Benefits under the Cash Balance Plan are based on employees' earnings and placed in a notional account that grows at a prescribed interest rate and is payable from the general assets of the pension fund. Rochow is a participant in the Cash Balance Plan. All employees in the Cash Balance Plan are now participants in the Defined Company Contribution Plan.

Defined Company Contribution Plan

Salaried employees, including NEOs, hired after June 30, 2003 (including anyone previously eligible for the Cash Balance Plan), are eligible to participate in the Defined Company Contribution Plan (“DCCP”), a tax-qualified, noncontributory, defined contribution plan. We provide a contribution ranging from 5% to 7% of regular compensation based on tenure to the DCCP on behalf of the employee. All of the NEOs are covered under the DCCP. For additional information regarding the DCCP, see DCCP, under Narrative to 2025 All Other Compensation Table, below.


CMS ENERGY 2026 PROXY STATEMENT			34

Defined Contribution Supplemental Executive Retirement Plan

The Corporation maintains a supplemental executive retirement plan that allows certain employees, including eligible NEOs, to receive benefits in excess of the benefits that would be payable under the DCCP. The Defined Contribution Supplemental Executive Retirement Plan (“DC SERP”) is a nonqualified tax deferred defined contribution plan established for employees, including NEOs, not eligible to participate in the Corporation's Defined Benefit SERP due to the employee's hire or promotion date. Each of the NEOs participate in the DC SERP. For additional information, see DC SERP, under Narrative to 2025 Nonqualified Deferred Compensation Table, below.

We believe that our retirement plans, including the DC SERP, are a useful part of the NEO compensation program and assist in the retention of our senior executives since benefits increase for each year that these executives remain employed by us and continue their work on behalf of our shareholders and customers. The DC SERP is designed to provide a predictable retirement income, while the equity plan is performance-based and variable and is designed to align the interests of NEOs with our shareholders and customers. Further, we believe both long-term focused plans are consistent with typical market practice and supportive of the philosophy to provide a competitive NEO compensation program.

Employees’ Savings Plans

Under the Employees’ Savings Plan for Consumers and affiliated companies, a tax-qualified defined contribution retirement savings plan (“Savings Plan”), participating employees, including NEOs, may contribute a percentage of their regular earnings into their Savings Plan accounts. For additional information, see Savings Plan, under Narrative to 2025 All Other Compensation Table, below. We maintain the Savings Plan for our employees, including the NEOs, because we wish to encourage our employees to save some percentage of their cash compensation for their eventual retirement. The Savings Plan permits employees to make such savings in a manner that is relatively tax-efficient.

Corporate Governance as it Relates to Executive Compensation

Stock Ownership Guidelines

We have established stock ownership guidelines for our officers. These guidelines require our officers to establish and maintain or maintain an equity stake in CMS and thereby more closely link their interests with those of our shareholders. These stock ownership guidelines provide that, within five years of becoming an officer or receiving a promotion to a higher ownership requirement, each officer must own shares of CMS common stock with a value of one to six times base salary, depending on his or her position. Shares of performance-based restricted stock and stock options are not counted toward stock ownership guidelines. All of our NEOs were in compliance with these guidelines as of December 31, 2025.

The following table illustrates the required NEO stock ownership guidelines for our NEOs:


Garrick J. Rochow			6X base salary
Rejji P. Hayes			3X base salary
Tonya L. Berry			3X base salary
Shaun M. Johnson			3X base salary
Brandon J. Hofmeister			2X base salary
LeeRoy Wells Jr.			2X base salary

Failure of an officer to comply with the guidelines will result in the following:

•all future restricted stock awards will have sale restrictions until compliance is achieved;

•if after three years, an officer is not actively making progress toward the guidelines, 50% of any annual incentive may be paid in shares of restricted stock at the discretion of the Compensation Committee;

•after the compliance deadline, officers will not be authorized to sell shares of CMS common stock if such a sale would cause them to drop below the ownership guidelines; and

•after the compliance deadline, a portion or all of any annual incentive will be paid in shares of restricted stock as necessary to bring the officer into compliance with the ownership guidelines.

Succession Planning and Management Development

The Compensation Committee oversees and regularly evaluates leadership succession planning practices and results. The Compensation Committee regularly reports to the Board on succession planning and advises on policies and principles for executive officer selection.


CMS ENERGY 2026 PROXY STATEMENT			35

Management's Role

Management works closely with the Compensation Committee in the executive compensation process. Except with respect to the CEO, management's responsibilities include:

•recommending performance measures and metrics that are formulated based on our corporate strategy and priorities;

•reporting executive performance evaluations;

•recommending base salary levels and other compensation, including equity awards; and

•recommending appointment of executives.

The CEO's compensation is determined solely by the Compensation Committee, which bases its decisions on performance and market studies along with participation and recommendations from its independent outside consultant.

Clawback Provisions

The Corporation maintains a clawback policy to comply with SEC and NYSE listing rules (the "Dodd-Frank Clawback Policy"). Under the Dodd-Frank Clawback Policy, the Corporation is required in certain situations to recoup incentive compensation paid or payable to certain current or former executive officers of the Corporation, including the NEOs, in the event of an accounting restatement due to the Corporation’s material noncompliance with any financial reporting requirement under the securities laws. Prior to the Dodd-Frank Clawback Policy, certain compensation and benefit plans included "clawback" provisions, which may apply in circumstances not covered by the Dodd-Frank Clawback Policy. These compensation and benefit plans continue to provide the Compensation Committee with the discretion to require the forfeiture and return of past benefits or awards if there is a restatement of financial results. The Compensation Committee may also, at its discretion, require a return of a benefit or award in the event of a mistake or accounting error in the calculation of such benefit or award.

(1)The amounts reported in this column include amounts deferred by the NEOs.

(2)The amounts represent the aggregate grant date fair value of the awards, which, with respect to those awards with a performance component, is based upon the probable outcome of the performance conditions, determined pursuant to ASC 718 and take into account the expected CMS common stock dividend yield associated with the 2023, 2024 and 2025 awards. See Note 12, Stock-based Compensation, to the Consolidated Financial Statements included in CMS' and Consumers' Annual Report on Form 10-K for the year ended December 31, 2025, for a discussion of the relevant assumptions used in calculating the aggregate grant date fair value pursuant to ASC 718. The TSR vesting condition related to the performance-based restricted stock awards is considered a market condition and not a performance condition under ASC 718. Accordingly, there is no grant date fair value below or in excess of the amounts reflected in the table above that could be calculated and disclosed based on achievement of market conditions. The EPS growth vesting condition is a performance condition under ASC 718.

The 2025 grant date fair value for the EPS growth performance-based restricted stock, based on the probable achievement of the performance goals at the time of grant, was $2,550,024 for Rochow; $787,515 for Hayes; $300,018 for Berry; $461,282 for Johnson; $344,968 for Hofmeister and $408,719 for Wells Jr.

The grant date fair value for the EPS growth performance-based restricted stock, assuming the maximum achievement of the performance goals, would have been $5,100,048 for Rochow; $1,575,030 for Hayes; $600,037 for Berry; $922,563 for Johnson; $689,936 for Hofmeister and $817,438 for Wells Jr.

(3)The amounts reported in this column for 2025 consist of cash incentive awards earned in 2025 under our Annual Incentive Plan.

(4)This column does not reflect compensation paid to the NEO but instead represents the aggregate annual increase, as of December 31, 2023, December 31, 2024 and December 31, 2025, in actuarial values of each of the participating NEO's benefits under the Cash Balance Plan. The actuarial values are calculated pursuant to Financial Accounting Standards Board Accounting Codification Topic 715, Compensation — Retirement Benefits (ASC 715), and take into account discount rates and implementation of the current 2021 mortality table. See Note 11, Retirement Benefits, to the Consolidated Financial Statements included in CMS' and Consumers' Annual Report on

Narrative to 2025 Summary Compensation Table

Employment Agreements

During 2025, none of the NEOs were employed pursuant to a traditional employment agreement with CMS or Consumers. Each NEO has entered into a Change-in-Control Agreement and an Officer Separation Agreement. Please see Potential Payments Upon Termination or Change-in-Control, below, for a description of such agreements.

Restricted Stock Awards

Please see Compensation Discussion and Analysis, The Elements of Our Executive Compensation Program, Equity Compensation, above for a description of the Stock Plan, pursuant to which restricted stock is awarded.

Cash Incentives

In 2025, the Compensation Committee established potential cash incentives for each of the NEOs under the 2025 Annual Incentive Plan. The amount of the potential incentive was tied to satisfaction of Annual Incentive EPS and Annual Incentive Utility targets approved by the Compensation Committee. The 2025 Annual Incentive Plan incentives were earned by the NEOs at 129% of target and are reported as “Non-Equity Incentive Plan Compensation” in the 2025 Summary Compensation Table. Please see Compensation Discussion and Analysis, The Elements of Our Executive Compensation Program, Cash Compensation, above for a description of the Annual Incentive Plan.

Salary and Incentive in Proportion to Total Compensation as Defined by the 2025 Summary Compensation Table

For 2025, the NEOs received between 32% and 55% of their total direct compensation in the form of base salary and target cash incentive awards under our Annual Incentive Plan. As noted above, we believe that a substantial portion of each NEO's compensation should be in the form of equity awards. We believe that our current compensation program gives the NEOs substantial alignment with shareholders, while also permitting us to provide incentive to the NEO to pursue specific annual and long-term performance goals. Please see Compensation Discussion and Analysis, Objectives of Our Executive Compensation Program, above for a description of the objectives of our compensation program and overall compensation philosophy.

Narrative to 2025 All Other Compensation Table

DCCP

Salaried employees, including NEOs, hired after June 30, 2003 are eligible to participate in the DCCP. Under the DCCP, CMS provides a contribution based on regular compensation tiered for tenure as follows: 0-5 years equals 5% (unless hired before January 1, 2016, 6%); 6-11 years equals 6% and 12 plus years equals 7%, up to the Internal Revenue Code of 1986, as amended ("IRC") compensation limit ($350,000 for 2025), to the DCCP on behalf of the employee which vests immediately and is payable upon termination of employment. Each of the NEOs participate in the DCCP and Rochow, Hayes, Berry, Johnson, Hofmeister and Wells Jr. receive contributions under the DCCP equal to 7%, 6%, 6%, 6%, 7% and 7%, respectively, of regular compensation.

Savings Plan

Under the Savings Plan for Consumers and affiliated companies, participating employees may contribute a percentage of their regular earnings into their Savings Plan accounts. NEOs, because they are considered highly compensated, may only contribute up to 20%, subject to the IRC annual dollar limit. In addition, under the Savings Plan, an amount equal to 100% of the first 6% of employees’ regular earnings contributions are matched by the Corporation. The matching contribution is allocated among the participant employees' investment choices. Amounts held in Savings Plan accounts may not be withdrawn prior to the employee’s termination of employment, or such earlier time as the employee reaches the age of 59½, subject to certain exceptions set forth in the IRC regulations.

(1)These amounts consist of cash awards under our Annual Incentive Plan. For each NEO, the payment was 129% of target and is reported as Non-Equity Incentive Plan Compensation in the 2025 Summary Compensation Table. These cash awards were granted and earned in 2025, with the payouts approved by the Compensation Committee in late January 2026 and the awards paid in February 2026.

(2)These awards consist of the performance-based restricted stock awarded under our Stock Plan. Seventy-five percent (75%) of the 2025 annual restricted stock awards were performance-based and vest 100% three years after the original award date, contingent on a comparison of TSR performance and EPS growth to the Performance Peer Group during the January 1, 2025 to December 31, 2027 performance period.

(3)These awards consist of the remaining 25% of the 2025 annual restricted stock awards awarded under our Stock Plan that vest based upon tenure only on the three-year anniversary of the award date.

(4)The amounts in column (j) are based upon the aggregate grant date fair value of the awards reported in columns (g) and (i) as determined pursuant to ASC 718, based upon probable outcome of the performance-based vesting conditions. See Note 12, Stock-based Compensation, to the Consolidated Financial Statements included in CMS' and Consumers' Annual Report on Form 10-K for the year ended December 31, 2025, for a discussion of the relevant assumptions used in calculating these amounts pursuant to ASC 718.

(1)Included in column (f) are the 2023 performance-based restricted stock awards, which vested based on a comparison of TSR to the Performance Peer Group over January 1, 2023 through December 31, 2025 performance period and recipient's continued service through January 26, 2026. Because the performance period concluded as of December 31, 2025, these awards are reported in column (f) as they remained subject to post-performance period tenure-based vesting requirements as of December 31, 2025. The number of shares reflects the actual shares earned based on the payout percentage achieved of 105.8%.

(2)Included in column (f) are the 2023 performance-based restricted stock awards, which vest based on a comparison of EPS growth to the Performance Peer Group over the January 1, 2022 through December 31, 2025 performance period and the recipient's continued service through March 26, 2026. Because the performance period concluded as of December 31, 2025, these awards are reported in column (f) as they remained subject to post-performance period tenure-based vesting requirements as of December 31, 2025. The Compensation Committee will not be able to determine performance until after March 26, 2026. For purposes of this table, we have included the awards based on 150% of the target level awarded.

(3)Outstanding shares of restricted stock (based upon the combination of tenure-based awards (column (f)) are reflected at the original share amounts awarded (other than as noted in footnotes (1) and (2) to these tables) and performance-based awards (column (h)) are reflected at the 50% percentage level for 2025 TSR shares and 2024 TSR shares, and at the 200% percentage level for 2025 EPS shares and at the 100% percentage level for 2024 EPS shares awarded under the Stock Plan).

For performance-based restricted stock awards, in lieu of dividends, recipients receive additional performance-based shares of restricted stock that will vest/forfeit based on CMS' performance and are included above.

(4)Calculated based upon the year-end closing price of CMS common stock of $69.93 per share.

(5)Per SEC regulations, the shares and dollars disclosed in the above table in columns (h) and (i), are based upon the threshold performance, unless prior year performance exceeds threshold, then it is based upon the next higher performance level in excess of prior year performance. Please see Compensation Discussion and Analysis, The Elements of Our Executive Compensation Program, Equity Compensation, above for a description of the Stock Plan.

(6)The performance vesting period for each performance-based grant is as follows:

2023: 1/1/2023 – 12/31/2025

2024: 1/1/2024 – 12/31/2026

2025: 1/1/2025 – 12/31/2027

CMS ENERGY 2026 PROXY STATEMENT			46

Narrative to 2025 Defined Benefit Table

Cash Balance Plan

The Cash Balance Plan is a funded, tax-qualified, noncontributory defined benefit plan. Benefits under the Cash Balance Plan are based on the employee's earnings. It is not an individual account but is a benefit payable from the general assets of the pension fund. Rochow is the only NEO with a benefit in the Cash Balance Plan.

The Cash Balance Plan credits an amount equal to 5% of base pay received from the year the participant began earning credits through any pay period before September 1, 2005 to a notional account. The credits were allocated on December 31 each year. The credits do not apply to incentive compensation amounts. The Cash Balance notional account is also increased annually with an interest credit based on the 30-year constant maturity treasury bond.

If employment ends under the Cash Balance Plan, participants may elect to receive their benefit at the time the employment terminates, or they may elect to defer benefits to a later date, but not later than age 70 ½. Participants have the following payment elections: (1) a monthly payment for life; (2) a monthly payment for life with a 50% or 75% payment to a spouse or other individual upon death; or (3) a single sum equal to account balance. Once payment begins under the Cash Balance Plan, no changes can be made to an election. If the choice was to defer receipt of benefits, interest credits will continue to be applied.

Effective September 1, 2005, the Cash Balance Plan was closed to new participants and any existing participants were eligible for the DCCP.

Narrative to 2025 Nonqualified Deferred Compensation Table

DSSP

An employee who has base salary (excluding any bonus, incentive or other premium pay) before deductions for taxes and other withholdings in excess of the IRC compensation limit is eligible and may elect to participate in the DSSP. The DSSP is an unfunded (for the purposes of ERISA) non-qualified tax deferred defined contribution plan. The DSSP is funded by CMS with trusts. However, participants have only an unsecured contractual commitment from the Corporation to pay the amounts due under the DSSP and any funds are considered general assets of the Corporation and are subject to claims of creditors.

A participant in the DSSP may elect in the prior year to defer 0% or 6% of his or her base salary that exceeds the IRC compensation limit and the Corporation will match 100% of the first 6% of the deferral, which is the same matching rate as the Savings Plan (equivalent to 6%). In addition, a DSSP eligible participant may elect an additional deferral of up to 50% of the participant's base salary for the calendar year. This additional deferral is not eligible for a Corporation match. The combined maximum total of the DSSP deferral amount and a 6% Savings Plan deferral is 62% of base salary. At the time a participant elects a deferral, a distribution election is also made for this class year deferral. Each class year deferral is payable either at a certain date five or more years in the future or upon separation from service with the Corporation either as a series of payments over two to 15 years or in a lump sum. The participant decides how Corporation contributions are invested among a broad array of mutual funds selected by us and provided by the record keeper.

Earnings in the DSSP are based on the change in market value of the mutual funds selected by the participant. All NEOs are eligible for the DSSP.

DC SERP

Pursuant to the DC SERP, employees with a title of executive director or above (and certain other employees) who are not participants in the Defined Benefit Supplemental Executive Retirement Plan are eligible to participate in the DC SERP. Under the DC SERP, the Corporation provides contributions in an amount ranging between 5% and 15% (depending on position and hire/promotion date) of each employee's regular earnings up to the IRC annual compensation limit, employee regular earnings in excess of the IRC annual compensation limit, and awards earned under the Annual Incentive Plan. Funds equal to the DC SERP are transferred to a mutual fund family at the time we contribute. Earnings or losses are based on the rate of return of the mutual funds selected by the participant. Although the DC SERP is funded by the Corporation, participants have an unsecured contractual commitment from us to pay the amounts due under this plan. Rochow, Berry, Johnson, Hofmeister and Wells Jr. each receive contributions under the DC SERP equal to 10% of regular earnings (above and below the IRC annual compensation limit) and 10% of awards earned under the Annual Incentive Plan, while Hayes receives contributions under the DC SERP equal to 10% of regular earnings below the IRC annual compensation limit, 15% of regular earnings above the IRC annual compensation limit, and 15% of his award under the Annual Incentive Plan. Contributions earned before 2019 are fully vested. For 2019 and beyond, contributions will become vested once the eligible NEO reaches age 55 with five years of participation in the Plan (with certain exceptions for death, disability or mandatory retirement).

Potential Payments upon Termination or Change-in-Control

As noted above under Compensation Discussion and Analysis, Post-Termination Compensation, Severance and Change-in-Control Benefits, our executives are eligible to receive separation and change-in-control benefits upon a qualifying termination of employment. These benefits are provided through two separate types of agreements:

•Officer Separation Agreements (“OS Agreements”) and

•Change-in-Control Agreements (“CIC Agreements”).

We have entered into OS Agreements and CIC Agreements with each of the NEOs. The OS Agreements provide for payments and other benefits if the officer is terminated under circumstances specified in the OS Agreement unrelated to a change-in-control (as defined in the CIC Agreements). The CIC Agreements provide for payments and other benefits only if the NEO is terminated under the circumstances specified in the CIC Agreements within two years following a change-in-control.

OS AGREEMENTS. The OS Agreements provide for payments of certain benefits, as described in the table below, upon circumstances of termination of the employment of the NEO. Central to an understanding of the rights of each NEO is an understanding of the definition of “Cause.” For purposes of these agreements, we have Cause to terminate the NEO if the NEO has engaged in any of a list of specified activities, including willful and continued failure to perform duties consistent with the scope and nature of his or her position, committing an act materially detrimental to the financial condition and/or goodwill of CMS or its subsidiaries, or is subject to a specified criminal legal action for activities relating to an act of fraud, embezzlement, theft or other act constituting a felony involving moral turpitude.

If the Corporation does not have Cause and terminates a NEO who has an OS Agreement for any reason, the NEO receives the benefits described in the table below.

These agreements require, as a precondition to the receipt of these payments, that the NEO sign a standard form of release in which he or she waives all claims that he or she might have against the Corporation and certain associated individuals and entities. These agreements also include non-disparagement and confidentiality provisions that would apply for an unlimited


CMS ENERGY 2026 PROXY STATEMENT			48

period of time following the NEO's termination of employment. Payments under these agreements are payable in a lump sum.

Under the OS Agreements, tenure-based restricted stock awards will vest on a pro-rata basis based upon the service provided prior to the termination date while performance-based restricted stock awards will vest at the end of the performance period on a pro-rata basis based on service provided during the performance period up to the termination date and actual performance of the Corporation.

Benefits for the NEOs under the OS Agreements are based on their executive career level (i.e., Senior Vice President, Executive Vice President, etc.).

CIC AGREEMENTS AND PROVISIONS. The CIC Agreements contain provisions that provide for payments in the event of a change-in-control. The change-in-control provisions (“CIC Provisions”) function in a manner similar to the severance provisions in the OS Agreements, except that NEOs become entitled to benefits under the CIC Provisions only in the event of a double trigger consisting of a change-in-control and qualifying termination of employment during the two-year period following the change-in-control. As part of the CIC Provisions, a portion of the severance payments to a terminated NEO is consideration for the NEO entering into a “non-compete” agreement.

A change-in-control of CMS is defined in the CIC Agreements to mean:

•the consummation of certain types of transactions, including mergers and the sale of all, or substantially all, of our assets;

•the acquisition by any person or entity of the beneficial ownership of securities representing 25% or 30% (depending upon the particular agreement) or more of the combined voting power of our then outstanding voting securities;

•a change in the composition of the Board such that individuals who at the effective date of the agreement constituted the Board and any new Directors elected or nominated by at least 2/3 of the Directors who were either Directors at the effective date of the agreement or were so elected or nominated, cease for any reason to constitute a majority of the Board; or

•the liquidation or distribution of all or substantially all of our assets.

The definitions of Cause and Good Reason are central to an understanding of the NEO's rights under the CIC Provisions. Under the CIC Provisions, “Cause” has the same meaning as set forth in the OS Agreements discussed above.

The NEO is said to have Good Reason to terminate his or her employment under the CIC Provisions if the assignment to the NEO of duties is materially inconsistent with his or her position (including status, offices, titles and reporting requirements), authority or responsibilities as in effect immediately prior to the change-in-control; the Corporation takes any action which results in a material diminution of the NEO's position, authority, duties or responsibilities as constituted immediately prior to the change-in-control (excluding an isolated, insubstantial and inadvertent action which is remedied by the Corporation promptly after receipt of notice thereof given by the NEO); there is a material reduction in the NEO's base salary, incentive opportunity, Stock Plan award level, benefits or status; or under other circumstances specified in the definition, including the relocation of the NEO's principal job location or office to more than 35 miles from its location at the time of entry into the CIC Agreement. Payments under the CIC provisions are payable in a lump sum.

The benefits to be provided to the NEOs in each of those situations are described in the table below, which assumes that the termination had taken place on December 31, 2025, the last business day of our most recent fiscal year.

The CIC Agreements with each NEO do not contain tax gross-up provisions with respect to IRC Section 280G and Section 4999 excise taxes. The CIC Agreements contain a “best net benefit” provision which provides that the Corporation's payments to the NEO can be reduced to the extent that no portion of the reduced payments shall be subject to the excise tax, but only if the NEO's net after-tax benefit is greater than his or her net after-tax benefit would have been if such reduction were not made and the NEO paid the excise tax.

Restricted stock under the CIC Agreements includes double-trigger vesting provisions (meaning, both a change-in-control and a qualifying termination of employment must occur in order for the equity to vest). Under the CIC Agreements, all performance-based restricted-stock awards will vest on a pro-rata basis based upon the service provided prior to the change-in-control date with any performance-based restrictions vesting at target level.

NEOs cannot receive benefits under both the CIC Agreements and OS Agreements.

RETIREMENT/DISABILITY/DEATH. Upon death, 100% of the restricted stock vests with any performance-based restricted stock vesting at target levels. Upon retirement or disability, tenure-based restricted stock awards will vest on a pro-rata basis based upon the service provided prior to retirement or disability while performance-based restricted stock awards vest at the end of the performance period on a pro-rata basis based on service provided during the performance period prior to the retirement or disability and actual performance of the Corporation during the performance period. In the case of retirement or disability, the Compensation Committee has the discretion, in exceptional circumstances, to waive the forfeiture of restricted stock awarded.

(1)Median employee occupies a union welding position in Michigan that requires a high level of background knowledge and qualifications in multiple technical areas.

For purposes of this disclosure, we utilized the same median employees that we identified for fiscal year 2024, as we believe that there have been no changes in our employee population or employee compensation arrangements that we believe would result in significant changes to this disclosure. In determining the median employee for each of CMS and Consumers in 2024, our calculation included employees as of October 31, 2024, as follows:

CMS, including Consumers

(1)Temporary employees include interns. There were no seasonal employees that were active as of October 31, 2024.

All employees are U.S.-based with the majority of our employee population in Michigan. Total compensation for purposes of determining the median employee is illustrated below by pay element. We identified each of CMS' and Consumers' median employees using these compensation measures, which were consistently applied to all employees.

The pay elements that were included in the annual total compensation to identify the median employee were:

•salary for all full-time and part-time permanent employees, based on salary level in effect as of October 31, 2024 and hours worked during the year;

•salary received in fiscal year 2024 for seasonal or temporary employees as of October 31, 2024;

•annual incentive target values for performance year 2024;

•grant date value of stock awards granted in fiscal year 2024;

•relocation, housing and/or auto allowance paid in fiscal year 2024; and

•reimbursement for Corporation-paid executive physical during fiscal year 2024.


CMS ENERGY 2026 PROXY STATEMENT			51

Once the annual total compensation was calculated for each employee using the above measures, the annual total compensation of all employees was ranked except for the President and CEO from lowest to highest, and the median employee was identified.

The median employee's compensation for fiscal year 2025 was calculated in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K as prescribed for inclusion in the 2025 Summary Compensation Table included in this Proxy Statement. With respect to the annual total compensation of the President and CEO, the amount reported in the “Total” column of our 2025 Summary Compensation Table included in this Proxy Statement was used.

Pay versus Performance

It is the philosophy of CMS and Consumers to provide executive compensation tied to performance. Pursuant to Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, the Pay Versus Performance Table (set forth below) is required to include “Compensation Actually Paid,” as calculated per SEC disclosure rules, to the Corporation's principal executive officer (“PEO”) and the Corporation's non-PEO NEOs, as noted below. “Compensation Actually Paid” represents a SEC required calculation of compensation that differs significantly from the Summary Compensation Table calculation of compensation, the NEO's realized or earned compensation, as well as from the way in which the Compensation Committee views annual compensation decisions, as discussed in the Compensation Discussion and Analysis. The amounts in the table below are calculated in accordance with SEC rules and do not represent amounts actually earned or realized by NEOs, including with respect to restricted stock awards which remain subject to forfeiture if the vesting conditions are not satisfied.

(5)The TSR Peer Group is the same peer group utilized in CMS' and Consumers' Annual Report on Form 10-K for the year ended December 31, 2025 and consists of utilities listed in the Standard & Poor's 400 Utilities Index, an independently prepared index that consists of companies in the utilities industry.

(6)As noted in the Compensation Discussion and Analysis, for 2025, the Compensation Committee determined that adjusted EPS continues to be viewed as a core driver of CMS’ performance and stockholder value creation and, accordingly, was utilized as a component for both the Annual Incentive Plan awards and LTI Awards. Adjusted EPS is a non-GAAP financial measure that represents EPS adjusted to exclude gains or losses on asset sales which have been excluded from adjusted EPS or are greater than or equal to 2% of adjusted EPS; changes in accounting principles resulting from new or revised accounting standards not included in the budget; large restructuring and severance expenses greater than $5 million or equal to $0.01 of EPS; 3rd party costs related to the business optimization initiative, and SAP S/4 Implementation project (greater or equal to $0.01 of EPS); legal and settlement costs or gains related to previously sold assets; regulatory recovery for prior year changes; changes in federal and state tax law (including legacy and Inflation Reduction Act); and unrealized gains or losses, recognized in net income, from mark-to-market adjustments related to NorthStar Clean Energy’s interest expense.

Relationship Between Pay and Performance

We believe the compensation actually paid, as calculated in accordance with SEC disclosure rules, in each of the years reported above and over the five-year cumulative period are reflective of the Compensation Committee's emphasis on “pay-for-performance” as the compensation actually paid fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our Annual Incentive Plan and long-term incentive program, including our adjusted EPS performance.

TSR: CMS versus Peer Group

As shown below, based on a 2020 investment, CMS' five-year cumulative TSR for the period of 2021-2025, for the utilities included within the S&P 500 and S&P 400 midcap indices.

Compensation Actually Paid Versus TSR

The following chart illustrates the relationship of CMS' five-year TSR to the compensation actually paid to the PEO, and the average for the other NEOs.


CMS ENERGY 2026 PROXY STATEMENT			54

Compensation Actually Paid Versus Net Income

Because a significant percentage of compensation is delivered in the form of equity awards with vesting tied to TSR, EPS growth and continued service, our executive compensation program is less impacted by fluctuations in net income. The following chart illustrates the relationship between net income and the compensation actually paid to the PEO and the average for the other NEOs.

Compensation Actually Paid Versus Adjusted EPS

As discussed above, adjusted EPS is viewed as a core driver of CMS' performance and stockholder valuation creation and, accordingly, was used as a component in both the Annual Incentive and LTI awards. Because the compensation actually paid, as calculated per SEC disclosure rules, is most greatly impacted by stock price fluctuations, the impact of year-over-year fluctuations in adjusted EPS performance has less of an impact on compensation actually paid as compared to stock price performance.

Performance Measures Used to Link Performance and Compensation Actually Paid to the NEOs

The following is a list of financial performance measures, which in the Corporation's assessment represent the most important financial performance measures used by the Corporation to link compensation actually paid to the NEOs for 2025. Please see the Compensation Discussion and Analysis for further information regarding how each of these measures is calculated and how they are used in the Corporation's executive compensation program, including the calculation of GAAP EPS to adjusted EPS for purposes of the Annual Incentive Plan awards and the LTI program. Our 2025 executive compensation program utilized financial metrics and supplemented those metrics in the Annual Incentive Plan with additional metrics tied to our operational performance, with goals relating to employee safety, culture, customer experience, electric reliability, waste elimination from cost reductions and methane emission reductions.

•Adjusted EPS (Annual Incentive)

•Relative EPS growth (LTI program)

•Relative TSR (LTI program)

PROPOSAL 2:

APPROVE, ON AN ADVISORY BASIS, EXECUTIVE COMPENSATION

Pursuant to Section 14A of the Exchange Act, we are conducting an advisory (non-binding) vote to approve our compensation programs for our NEOs as disclosed in this Proxy Statement in accordance with SEC rules. The Compensation Committee did not make any changes to our executive compensation program since the last shareholder vote, which strongly favored the program (approximately 93% and 100% of each of CMS and Consumers votes cast, respectively, were affirmative).

As described in detail under Compensation Discussion and Analysis in this Proxy Statement, the Corporation's NEO compensation program is organized around four principles: (1) align with increasing shareholder and customer value; (2) enable the Corporation to compete for and secure top executive talent; (3) reward measurable results; and (4) be fair and competitive.

We have designed our executive compensation elements based on balance and simplicity to place emphasis on consistent, sustainable and superior absolute and relative performance.

•Base salary is targeted to approximate the median of a Compensation Peer Group, which is made up of companies of similar business profile and size, with adjustments to reflect individual performance and internal considerations.

•Annual incentive awards are based on the achievement of annual goals.

•A majority of our LTI program is delivered through performance-based restricted stock with tenure-based restricted stock representing a minority of LTI at 25%. The performance-based portion is eligible to vest after three years dependent upon our TSR performance and LTI EPS growth, each weighted equally, relative to the Corporation's Performance Peer Group, while the tenure-based portion vests on the third anniversary of the award date.

We annually review all elements of the Corporation's executive compensation program and, in addition to designing a program to comply with required rules, we adopt current best practices where deemed appropriate for our business and shareholders. As a result, we have:

•a majority of pay in variable elements;

•a majority of variable pay in LTI awards;

•a majority of LTI delivered in performance-based restricted stock;

•all LTI denominated and settled in equity;

•LTI payouts capped at target if three-year absolute total shareholder return performance is not positive;

•a balance of absolute and relative metrics used in annual incentives and LTI;

•stock ownership guidelines for NEOs, which exclude stock options and unvested performance-based restricted stock awards when determining compliance;

•change-in-control agreements that require a double-trigger for the accelerated vesting of equity awards;

•a policy that prohibits hedging and pledging of the Corporation's securities by officers;

•annual reviews of risk within our incentive programs;

•annual reviews of our Compensation Peer Group and Performance Peer Group;

•regular briefings from the Compensation Committee's independent compensation consultant regarding key trends and legislative and regulatory updates;

•no excessive perquisites; no planes, cars, clubs, or financial planning with an annual physical examination being the principal perquisite provided to our executives in 2025;

•no dividends paid on unvested performance-based restricted stock awards; in lieu of dividends, recipients receive additional shares of restricted stock that are contingent on the same performance measures and forfeiture conditions applicable to the underlying restricted stock;

•no employment agreements - our executive agreements are limited to separation and change-in-control agreements with base salary and annual incentive separation amounts not exceeding three times the NEO's base salary and annual incentive amount, with an average of two times; and

•no tax gross-ups - none of our separation or change-in-control agreements contain tax gross-ups.

Shareholders are encouraged to read the Compensation Discussion and Analysis, the accompanying compensation tables and the related narrative disclosure.

This proposal gives our shareholders the opportunity to express their views on the overall compensation of the NEOs and the compensation philosophy, policies and practices disclosed in this Proxy Statement. For the reasons discussed above, we are


CMS ENERGY 2026 PROXY STATEMENT			57

asking our shareholders to indicate their support for the NEO compensation by voting FOR the following resolution at the Annual Meeting:

RESOLVED: That the compensation paid to the named executive officers, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and the related narrative disclosure, is APPROVED.

This vote is an advisory vote only, and therefore it will not bind CMS or Consumers, the Board or the Compensation Committee. The vote results will not create or imply any change to fiduciary duties or create or imply any additional fiduciary duties for CMS or Consumers or the Board. However, we value the opinions that our shareholders express in their votes and will consider the outcome of the vote when making future executive compensation decisions as they deem appropriate.

Consistent with the direction of the CMS and Consumers shareholders at the 2025 Annual Meeting of Shareholders, the advisory vote on NEO compensation for CMS and Consumers is held on an annual basis.


The CMS and Consumers Boards recommend that shareholders vote to approve the non-binding advisory proposal to approve the compensation of the named executive officers as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and the related narrative disclosure.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee, comprised solely of independent Directors, assists the Board of Directors in its oversight of the 1) integrity of financial statements; 2) performance of the internal audit function and independent auditors; 3) independent auditor's qualifications and independence; and 4) compliance with applicable legal and regulatory requirements. The Audit Committee has a written charter that complies with New York Stock Exchange requirements. Management has the primary responsibility for the preparation, presentation and accuracy of the consolidated financial statements and the financial reporting process, including the systems of internal controls.

The Audit Committee reviewed and discussed with management the audited consolidated financial statements set forth in CMS' and Consumers' 2025 Annual Report to Shareholders and Form 10-K for the year ended December 31, 2025. The Audit Committee also discussed with PricewaterhouseCoopers LLP (“PwC”), who are responsible for performing an independent audit of CMS' and Consumers' financial statements and expressing an opinion on the conformity of those audited consolidated financial statements with United States generally accepted accounting principles, the matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and SEC rules.

The Audit Committee has received a report on the quality control procedures of PwC. The Audit Committee has also discussed with management, the internal auditors and PwC the quality and adequacy of CMS' and Consumers' internal controls, with particular focus on compliance with Section 404 of the Sarbanes-Oxley Act of 2002. The Audit Committee reviewed with the internal auditors and PwC their audit plans and audit scope.

The Audit Committee is responsible for the appointment, termination, compensation and oversight of the work of the independent auditor. PwC has served as CMS' and Consumers' independent registered public accountants since 2007. In order to assure continuing auditor independence, the Audit Committee periodically considers whether there should be a regular rotation of the independent registered public accounting firm. In conjunction with the mandated rotation of the lead engagement partner, the Audit Committee and its Chair are directly involved in the selection of PwC's lead engagement partner. The Audit Committee has received from PwC the written communications required by applicable requirements of the PCAOB regarding PwC's communications with the Audit Committee concerning independence and have discussed with PwC their independence from CMS and Consumers. The Audit Committee has discussed with PwC the compatibility of non-audit services with the auditor's independence and has satisfied themselves as to PwC's independence.

In reliance on the review and discussions referred to above, the Audit Committee recommended to the Boards that the audited consolidated financial statements be included in CMS' and Consumers' Annual Report on Form 10-K for the fiscal year ended December 31, 2025, for filing with the SEC.

FEES PAID TO THE INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM

PwC was the principal independent registered public accounting firm for CMS and Consumers for the years 2025 and 2024. The following table sets forth the aggregate fees, including expenses, for professional services, billed and audit fees expected to be billed by PwC to CMS (consolidated total including Consumers and its subsidiaries) and Consumers (including its subsidiaries), for each of the last two fiscal years.


	CMS				Consumers
	2025		2024		2025		2024
Audit Fees	$	6,157,373	$	5,523,000	$	5,150,656	$	4,906,386
Audit-related	312,500		200,000		312,500		—
Tax Fees	—		—		—		—
All Other Fees	12,000		2,000		12,000		2,000
Total Fees	$	6,481,873	$	5,725,000	$	5,475,156	$	4,908,386

Audit fees include fees associated with the annual audit, the reviews of our quarterly reports on Form 10-Q, comfort letters, required statutory audits, fees related to the audit of our internal controls over financial reporting as required by the Sarbanes-Oxley Act of 2002 and other attest services. Audit-related fees include fees associated with assistance related to accounting systems and controls. There were no tax services provided during 2025 or 2024. All other fees consist of costs for benchmarking services, research tools and other minor expenses.

The Audit Committee has adopted a policy that requires pre-approval for all audit, audit-related, tax and other services performed by the independent registered public accounting firm. The policy provides for pre-approval by the Audit Committee of specifically defined audit and non-audit services. Unless the specific service has been previously pre-approved with respect to that year, the Audit Committee must approve the permitted service before the independent registered public accounting firm is engaged to perform it. The Audit Committee has delegated to the Chair of the Audit Committee authority to approve permitted services, provided that the Chair reports any decisions to the Audit Committee at its next scheduled meeting. All of the services performed by the principal independent registered public accounting firm were approved in accordance with the policy in 2025.


CMS ENERGY 2026 PROXY STATEMENT			60

PROPOSAL 3:

RATIFY THE APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee's selection of the independent auditor will be submitted to our shareholders for their ratification at the Annual Meeting of Shareholders. If a majority of shares voted do not ratify the Audit Committee's selection, the Audit Committee will consider our shareholder views when considering selection of a different independent auditor or the continued retention of the existing auditor for that year.

The Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the independent registered public accounting firm (taking into account the vote on shareholder ratification). The Audit Committee has selected PwC, independent registered public accounting firm, to audit the consolidated financial statements for the year 2026. PwC has served as our independent registered public accountants since 2007. The Audit Committee is responsible for the audit fee negotiations associated with the retention of PwC. In order to assure continuing auditor independence, the Audit Committee periodically considers whether there should be a regular rotation of the independent registered public accounting firm. In conjunction with the mandated rotation of the lead engagement partner, the Audit Committee and its Chair are directly involved in the selection of PwC's lead engagement partner. The members of the Audit Committee and the Board believe that the continued retention of PwC as independent registered public accounting firm is in the best interests of the Corporation and its shareholders. A representative of PwC will be present at the Annual Meeting and will have an opportunity to make a statement and respond to appropriate questions.


The CMS and Consumers Boards and their Audit Committees recommend a vote to ratify the appointment of the independent registered public accounting firm for 2026.

PROPOSAL 4:

APPROVE AN AMENDMENT TO THE CMS RESTATED ARTICLES OF INCORPORATION INCREASING THE NUMBER OF AUTHORIZED SHARES OF CMS COMMON STOCK FROM 350 MILLION SHARES TO 700 MILLION SHARES

The CMS Board has unanimously approved and recommends that shareholders approve an amendment to our Restated Articles of Incorporation to increase the number of authorized shares of CMS Common Stock, par value $.01 per share ("Common Stock"), from 350 million shares to 700 million shares. The authorized number of shares of our preferred stock, par value $.01 per share, will remain at 10 million. Therefore, as a result of the proposed amendment, our total authorized capital stock will increase from 360 million shares to 710 million shares. Specifically, the CMS Board recommends that the first paragraph of Article III of the Corporation's Restated Articles of Incorporation should be amended to read as follows:


The total number of shares of all classes of stock which the Corporation shall have authority to issue is 710,000,000, of which 10,000,000 shares, par value $.01 per share, are of a class designated Preferred Stock (“Preferred Stock”), and 700,000,000 shares, par value $.01 per share, are of a class designated Common Stock (“Common Stock”).

As of March 10, 2026, of the 350 million shares of CMS Common Stock authorized for issuance:

•approximately 308 million shares were outstanding;

•approximately 27 million shares were reserved for issuance upon conversion of our outstanding convertible securities;

•approximately 5 million shares were reserved for issuance under our employee benefit and shareholder stock purchase plans; and

•approximately 8 million shares were reserved for issuance under our equity distribution agreement.

Accordingly, there are approximately 2 million authorized shares of CMS Common Stock available for future issuances of any type. The CMS Board believes that it is prudent to approve the proposed increase in authorized Common Stock in order to provide the flexibility necessary to issue additional shares of CMS Common Stock as needed for general corporate purposes. In particular, the proposed increase is requested to make available sufficient shares for possible future stock splits, stock dividends, employee benefit and shareholder stock purchase plans issuances, equity and equity-linked financings, acquisitions and other general corporate purposes.

We do not currently have any specific transaction or plan that requires an increase in the number of authorized shares of CMS Common Stock. Authorized but unissued shares of CMS Common Stock may be issued at such time, for such purposes, and for such consideration as the CMS Board may determine without the requirement of further action by shareholders, except as required by applicable corporate law, stock exchange policies or our Restated Articles of Incorporation.

We have not proposed the increase in the authorized number of shares of CMS Common Stock with the intention of using the additional shares for anti-takeover purposes, although an issuance of additional shares could, in certain circumstances, make an attempt to acquire control of CMS more difficult. We are not at this time aware of any such attempts and we are not proposing this increase in response to any third-party effort to acquire control of CMS.

The adoption of the proposed amendment to the CMS Restated Articles of Incorporation to increase the number of authorized shares of CMS Common Stock from 350 million shares to 700 million requires a majority vote of the outstanding shares of CMS Common Stock. Thereafter, it will become effective upon filing a Certificate of Amendment with the Secretary of State of the State of Michigan, which we would make promptly after the Annual Meeting.


The CMS Board unanimously recommends that CMS shareholders vote to approve the Proposed Amendment to increase the number of authorized shares of CMS Common Stock.


CMS ENERGY 2026 PROXY STATEMENT			62

PROPOSAL 5:

APPROVE AN AMENDMENT TO THE CMS RESTATED ARTICLES OF INCORPORATION TO ALLOW SHAREHOLDERS TO CALL A SPECIAL MEETING

Currently, the CMS Restated Articles of Incorporation (“CMS Articles”) state that special meetings of the shareholders may be called only by the Board or the Chairman of the Board. This ensures that the interests of all shareholders are fully protected, particularly minority shareholders. However, the CMS Board has been mindful of the ongoing corporate governance developments and debates regarding the ability of shareholders to call a special meeting and has examined this issue, including the results of last year’s shareholder vote on a non-binding proposal to provide the right for shareholders to call a special meeting at a 10% ownership threshold. The CMS Board, taking into account the recommendation of the Governance Committee, considered the advantages and disadvantages of allowing shareholders to call a special meeting. The CMS Board also considered that, even with the ability of shareholders to call a special meeting, CMS has appropriate safeguards in its governance structure to protect the interests of all shareholders. After balancing these considerations, the CMS Board has determined that it is in the best interests of CMS and its shareholders to amend the CMS Articles to allow shareholders to call a special meeting.

Consequently, the CMS Board recommends that Article V of the CMS Articles be amended to allow shareholders of 10% of the outstanding shares entitled to vote thereon to call a special meeting (“Proposed Amendment”). The text of the Proposed Amendment of Article V, marked to show the changes from the current Article V is as follows:

ARTICLE V


Special meetings of the shareholders may be called only by the Board of Directors, or by the Chairman of the Board, or shareholders entitled to cast at least 10% of the outstanding shares entitled to vote thereon. The procedure to be followed by shareholders in calling a special meeting and the methodology for determining the percentage of votes entitled to be cast by the shareholders seeking to call a special meeting (including without limitation any minimum holding periods or other limitations or conditions) shall be as set forth in the bylaws of the Corporation.

The Proposed Amendment to allow shareholders to call a special meeting will be approved if a majority of the outstanding shares entitled to vote as of the Record Date are voted in favor of the Proposed Amendment. Thereafter, it will become effective upon filing a Certificate of Amendment with the Secretary of State of the State of Michigan, which we would make promptly after the Annual Meeting. If the Proposed Amendment is approved by our shareholders, the CMS Board intends to approve corresponding amendments to our Bylaws. The proposed special meeting Bylaw amendments are contemplated to include customary procedural requirements.


The CMS Board recommends that CMS shareholders vote to approve the Proposed Amendment to allow shareholders to call a special meeting in the CMS Articles of Incorporation.

VOTE ON A SHAREHOLDER PROPOSAL – SHAREHOLDER RIGHT TO ACT BY WRITTEN CONSENT

To Be Voted On By CMS Shareholders Only

This shareholder proposal has been submitted by John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278 (the beneficial owner of not less than 80 shares of CMS common stock.) The proponent has requested we include the proposal and supporting statement in this proxy statement, and, if properly presented, the proposal will be voted on at the Annual Meeting. This proposal and supporting statement are quoted verbatim below, and CMS is not responsible for any inaccuracies contained in them.

The CMS Board has recommended a vote against this proposal. The CMS response is set forth immediately following the proposal.

Shareholder Right to Act by Written Consent

Shareholders request that the board of directors take the necessary steps to permit written consent by the shareholders entitled to cast the minimum number of votes that would be necessary to authorize an action at a meeting at which all shareholders entitled to vote thereon were present and voting (without any discrimination or restriction based on length of stock ownership). This includes shareholder ability to initiate any appropriate topic for written consent.

Shareholders acting by written consent and calling for a special shareholder meeting are 2 means that shareholders of a company can use to put forth a proposal on a timely basis without waiting for the annual shareholder meeting.

Acting by written consent is hardly ever used by shareholders but the main point of having a right to act by written consent is that it gives shareholders greater standing to engage effectively with management when CMS Energy is underperforming.

Now could be a good time for this proposal due to the long-term underperformance of CMS stock. CMS stock was at $69 in 2020 and at only $72 in late 2025 despite a robust stock market. If CMS directors and management know that CMS shareholders can act by written consent they will have a greater incentive to perform.

Challenging news reports regarding CMS emerged in 2025 and it would be easy for shareholders to find similar news reports for 2026.

CMS faces ongoing risks related to the significant expenditures required for the closure of solid waste disposal facilities for coal ash, as well as tightening environmental regulations on carbon emissions.

The company's non-utility segment saw a negative earnings per share (EPS) variance of $0.42 (adjusted, for the first nine months of 2025) due primarily to a planned outage at the Dearborn Industrial Generation facility and increased parent financing costs.

Despite overall positive trends in the broader industry, CMS Energy's stock performance in the 3-months leading up to November 2025 lagged behind industry growth (1.7% increase compared to the industry's 8% growth).

CMS ENERGY 2026 PROXY STATEMENT			64

CMS Board of Directors’ Recommendation Against the Shareholder Proposal and Statement of Opposition

After careful consideration, the CMS Board has concluded that this proposal is not in the best interests of CMS and its shareholders. The CMS Board recommends a vote AGAINST this proposal for the following reasons:

1.CMS has a strong corporate governance framework that promotes CMS Board accountability and protects the interests of all shareholders.

2.CMS has a strong history of long-term performance.

3.Shareholder action by written consent has the potential for misuse.

4.Shareholders should vote on matters at a meeting where all shareholders can participate.

5.CMS has multiple channels for shareholder engagement and communication with the CMS Board to raise matters between annual meetings.

6.Shareholder action by written consent is duplicative of shareholders’ right to call special meetings, but without important protections and advantages afforded by the shareholder meeting process. At the Annual Meeting, shareholders are being asked to approve an amendment to the CMS Amended and Restated Articles of Incorporation to provide shareholders with the right to call special meetings (see Proposal 5).

CMS has a strong corporate governance framework that promotes CMS Board accountability and protects the interests of all shareholders.

The CMS Board and management continually review and monitor governance trends and best practices. The CMS Board believes that CMS’ existing corporate governance framework is in line with best practices and promotes Director accountability while protecting the interests of all shareholders.

As further described in this Proxy Statement, CMS’ corporate governance practices include:

•91% of our Directors are independent

•100% independent Directors on Audit, Compensation, Finance and Governance Committees

•Annual election of all Directors

•Simple majority voting provisions in our Amended and Restated Articles of Incorporation and Bylaws

•Majority voting standard for uncontested Director elections

•Annual advisory say-on-pay

•Independent Directors meet regularly in executive sessions

•Strong Board and management succession planning process

•Robust stock ownership guidelines for Directors and executive officers

•Policy prohibiting Directors and officers from pledging or hedging our stock

•Proxy access bylaws

•Proactive shareholder engagement

•Annual Board and Committee Self-evaluations

•Individual Director peer evaluation

•Chairman of the Board is independent and separate from the CEO

•Amending our Amended and Restated Articles of Incorporation to provide shareholders the right to call special meetings (subject to shareholder approval at the Annual Meeting)

Taken together, these practices provide shareholders with meaningful rights and effective oversight mechanisms without the risks associated with shareholder action by written consent.

CMS has a strong history of long-term performance.

Contrary to the assertions in the proponent’s supporting statement, CMS has delivered consistent long-term performance. CMS has increased its dividend for 20 consecutive years, reflecting a sustained commitment and execution of CMS’ strategy. In addition, CMS has reported strong financial results for 23 consecutive years, demonstrating resilience across economic and industry cycles.


CMS ENERGY 2026 PROXY STATEMENT			65

Shareholder action by written consent has the potential for misuse.

The written consent process does not guarantee that all shareholders are informed of the proposed action or can meaningfully participate in the decisions to the same extent as in a shareholder meeting. The proposal does not impose any ownership requirements on the shareholders soliciting written consent and, as a result, could be initiated by a single shareholder holding a very small number of shares which could require CMS to dedicate a significant amount of time and corporate resources to this single shareholder at the expense of the broader shareholder base. In contrast, CMS’s proposed special meeting right requires a 10% ownership threshold for shareholders seeking to initiate the special meeting process, protecting all shareholders by requiring a meaningful ownership of CMS stock before requiring CMS to initiate the process.

Written consent rights of the type proposed may also encourage accumulation of short-term share ownership by a small group of investors (including those who accumulate a short-term voting position through borrowed shares) to advance a special agenda that may not align with the long-term best interests of CMS and its shareholders. The CMS Board believes that disallowing action by written consent protects CMS against waste of corporate resources and disruption associated with convening any unnecessary costs.

Shareholders should vote on matters at a meeting where all shareholders can participate.

The CMS Board believes that a shareholder meeting (whether an annual meeting or a special meeting) better serves shareholders’ interests than action by written consent as it is an inherently more structured and transparent process and helps to ensure the accuracy and completeness of information presented to all shareholders for their consideration. The CMS Board believes that every shareholder’s vote is important and deserves consideration. Any action taken by written consent could prevent all shareholders from having an opportunity to deliberate, and to consider arguments for and against any action, including CMS’ position. During a meeting, shareholders have the ability to ask questions and may change their vote.

In addition, a shareholder seeking action by written consent may attempt to solicit the fewest possible shareholders to take action, rather than seeking input from all shareholders, and may rely on consents obtained from some shareholders before other shareholders have had the ability to evaluate a proposal and vote. As a result, some shareholders may not even be aware of the proposed action until after the written consent process.

All communications regarding proposed actions to be taken at a meeting of shareholders are governed by SEC rules that require fair and timely disclosure. Accordingly, complete and accountable information about any proposed shareholder action is broadly distributed in advance of the meeting through proxy statement materials.

Permitting shareholder action by written consent could also lead to confusion and disruption, with potentially multiple, and even conflicting, written consent solicitations by different shareholder groups at the same time.

CMS has multiple channels for shareholder engagement and communication with the CMS Board to raise matters between annual meetings.

As part of its overall corporate governance framework, CMS has an ongoing outreach program to develop and maintain communication with its investors. We value these discussions and the CMS Board considers relevant investor feedback. In addition, management regularly participates in investor and industry conferences throughout the year to discuss performance and sustainability matters and to share its perspective on business and industry developments. As further described in this Proxy Statement, shareholders may also contact the CMS Board, any committee, the independent Directors as a group or an individual Director, including the Chairman or Presiding Director, with any inquiry or issue. Additionally, once Proxy Materials are distributed, shareholders may submit questions on the voting website prior to the Annual Meeting and during the Annual Meeting. Through all of these channels, CMS receives shareholder input, provides additional information, and addresses questions regarding corporate strategy, executive compensation programs, corporate governance, and other topics of interest to shareholders.

Shareholder action by written consent is duplicative of shareholders’ right to call special meetings, but without important protections and advantages afforded by the shareholder meeting process.

A right to act by written consent is one way for shareholders to take action between shareholder meetings, but it is duplicative of the right to call a special meeting and inferior to the shareholder meeting process, as described above. The CMS Board has recommended shareholders vote for Proposal 5, which is an amendment to the CMS Amended and Restated Articles of Incorporation to allow shareholders of 10% of CMS common stock to call a special shareholder meeting. The proposed 10% stock ownership threshold is lower than the most common threshold amount of S&P 500 companies that provide the right for shareholders to call a special meeting, providing a meaningful and orderly pathway for minority shareholders to bring important matters to the attention of all shareholders through the special meeting process.

Conclusion

In summary, the CMS Board has determined that the adoption of the shareholder right to act by written consent requested by the shareholder proposal is not in the best interests of CMS and its shareholders at this time. The CMS Board believes that CMS’ existing corporate governance promotes accountability, protects shareholder interests and provides shareholders with


CMS ENERGY 2026 PROXY STATEMENT			66

meaningful ways to raise their concerns, such that implementing this proposal is unnecessary and unwarranted. Furthermore, the CMS Board believes that the shareholder right to act by written consent as requested in the proposal is potentially costly, wasteful, unnecessary and an imprudent use of CMS’ time and resources.


The CMS Board recommends a vote AGAINST the shareholder proposal: shareholder right to act by written consent.

(1)Abstentions, withhold votes and broker discretionary votes are counted toward establishing a quorum.

(2)Holders of Consumers' preferred and common stock are entitled to one vote for each share and shareholders have cumulative voting rights for the election of Directors. Please see "Who is entitled to vote?" below.

(3)This is considered to be a routine matter and, therefore, if you hold your shares in street name and do not provide voting instructions to the broker, bank or other nominee that holds your shares, the nominee has discretionary authority to vote on this Proposal. This is not the case for any of the other Proposals since they are considered to be "non-routine" matters and a "broker non-vote" will occur as to such matters if your shares are otherwise voted on another proposal presented at the Annual Meeting.

We are not aware of any other matters to be presented at the Annual Meeting. However, if any other matters (including matters incident to the conduct of the meeting) are properly presented at the meeting, it is intended that the holders of the proxies will vote in their discretion.

Why did I receive a Notice of Availability of Proxy Materials?

To reduce the environmental impact of our Annual Meeting, we are providing the Proxy Materials over the Internet. As a result, we are sending many of our shareholders a Notice of Availability instead of a paper copy of the Proxy Materials. All


CMS ENERGY 2026 PROXY STATEMENT			69

shareholders receiving the Notice of Availability may access the Proxy Materials over the Internet and request a paper copy by mail. Instructions on how to access the Proxy Materials, vote online and request a paper copy can be found in the Notice of Availability. The Notice of Availability also contains instructions on how to request delivery of Proxy Materials in paper form or electronically on an ongoing basis.

How can I access the Proxy Materials electronically or sign up for electronic delivery?

All shareholders can view, search and print the Proxy Materials at cmsenergy.com/investor-relations/corporate-overview/default.aspx.

If you are a shareholder of record and you received printed Proxy Materials, you may elect to receive future Proxy Materials electronically. To do so you must enroll online at proxyvote.com. If you consent to receive Proxy Materials electronically, you will receive an e-mail notification when they become available. Your enrollment will be effective until revoked.

This electronic option allows you to:

•gain faster access to Proxy Materials;

•reduce the amount of mail you receive; and

•help reduce the costs of our Annual Meeting.

If your shares are held in street name you should contact your brokerage firm, bank or other nominee and inquire about their electronic delivery options.

Who is entitled to vote?

Shareholders as of the close of business on the record date, March 10, 2026, are entitled to vote at the Annual Meetings. As of the record date, CMS’ outstanding securities entitled to vote consisted of 307,996,751 shares of CMS common stock. Each share is entitled to one vote on each matter presented at the CMS Annual Meeting.

As of the record date, Consumers' outstanding securities entitled to vote consisted of 84,108,789 shares of common stock held by CMS and 373,148 shares of preferred stock held by the public. Holders of Consumers’ preferred and common stock are entitled to one vote for each share and shareholders have cumulative voting rights for the election of Directors. That is, holders of preferred and common shares are entitled to cast as many votes as equal the number of shares held multiplied by the number of Directors to be elected, and they may cast all of such votes for a single nominee or distribute them among any two or more nominees as they choose.

A list of CMS and Consumers shareholders entitled to vote at the Annual Meeting will be available during the Annual Meeting for examination by any shareholder at virtualshareholdermeeting.com/CMS2026 and virtualshareholdermeeting.com/CMSPB2026. Your confidential vote is received and tabulated by an independent inspector of election. Your vote will not be disclosed except as required by law or in other limited circumstances.

What is the difference between a shareholder of record and a “street name” holder?

If your shares are registered directly in your name, you are considered a shareholder of record for those shares.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of the shares and your shares are said to be held in “street name.”

How do I vote?

You can ensure that your shares are voted at the Annual Meeting by submitting your vote by Internet (the instructions are found on your proxy card, voting instruction form or Notice of Availability). If you received your Proxy Materials by mail, you can also vote by telephone or complete and return your proxy card or voting instruction form by mail. Even if you vote by one of these methods, you can still attend and electronically vote at the Annual Meeting.

If your shares are held in street name, you must vote your shares in the manner prescribed by your brokerage firm, bank or other nominee. Your brokerage firm, bank or other nominee should provide a voting instruction form for you to use in directing it how to vote your shares.

What if I do not indicate my voting preference on my proxy?

If your shares are voted by proxy, the shares will be voted as you instruct. If you sign and properly submit your proxy, but do not give any specific voting instructions, your shares will be voted as the Board recommends. Your shares will also be voted as recommended by the Board, in its discretion, on any other business that is properly presented for a vote at the Annual Meeting.

Can I change my vote after I have voted or can I revoke my proxy?

Yes. If you are a shareholder of record, you can change your vote or revoke your proxy at any time prior to the Annual Meeting by:

•providing another signed proxy that is dated later than the vote you want to change;


CMS ENERGY 2026 PROXY STATEMENT			70

•voting by telephone or Internet and recording a different vote; or

•attending and electronically voting at the Annual Meeting.

How many shares must be present to hold the Annual Meeting?

To constitute a quorum and transact business, shareholders of a majority of the outstanding shares entitled to vote must be present in person or by proxy at each of the Annual Meetings.

What does it mean if I get more than one set of Proxy Materials?

You may receive multiple copies of Proxy Materials if your shares are registered differently (i.e., trust, joint, name spelling variation, etc.) and/or if they are in more than one account (i.e., brokerage firm, bank, transfer agent, etc.). If you wish to consolidate accounts, please contact Equiniti Trust Company at 1-855-598-2714. Please vote all of the proxies that you receive and consider consolidating accounts.

If your household receives multiple copies of the Proxy Materials or Notice of Availability, you may authorize us to discontinue duplicate mailings in the future by electing the option when you vote, see “What is “householding” and how does it affect me?” below for additional householding information.

If your shares are held in street name and you are receiving multiple sets of the Proxy Materials and wish to consolidate accounts, please contact your brokerage firm, bank or other nominee.

What is “householding” and how does it affect me?

We have adopted a procedure called “householding” which has been approved by the SEC. Householding is intended to reduce the volume of duplicate information received by a household and the cost of preparing and mailing duplicate information. Under this procedure, we are permitted to mail only one Notice of Availability or one set of Proxy Materials to multiple shareholders who share an address and who have consented to or have received prior notice of our intent to do so, so long as we have not received contrary instructions from one or more such shareholders. Consent for householding will remain in effect until revoked.

To resume the mailing of individual copies of future Proxy Materials or Notice of Availability and revoke your consent to householding, submit a written request to Broadridge Householding Dept., 51 Mercedes Way, Edgewood, New York 11717, or make a request by telephone to 1-866-540-7095. If you participate in householding and wish to receive separate Proxy Materials or Notices of Availability, we will promptly mail a copy if you notify us by making a written request to our Shareowner Services Department at One Energy Plaza, Jackson, Michigan 49201, or making a request by telephone to 1-517-788-1576.

If your shares are held in street name, you can request information about householding by contacting your brokerage firm, bank or other nominee.

Who conducts the proxy solicitation and how much will it cost?

We are requesting your proxy for the Annual Meeting and will pay the costs of requesting shareholder proxies. Proxies may be solicited by Directors, officers and other employees, personally or by telephone, Internet or mail, none of whom will receive compensation for their solicitation efforts. We have arranged for D.F. King to solicit proxies for a fee of $16,000, plus expenses and disbursements. We will pay all proxy solicitation costs. We may also reimburse brokerage firms, dealers, banks, voting trustees or other record holders for their reasonable expenses for forwarding Proxy Materials to beneficial owners of CMS and Consumers stock.

How can I attend the Virtual Annual Meeting?

Our Annual Meeting will be a virtual meeting. There will be no physical meeting location; the meeting will be conducted via webcast. The virtual meeting increases attendance by providing Annual Meeting access to all of our shareholders, regardless of where they live. Additionally, in-line with CE Way and our use of Lean strategies, the virtual meeting format eliminates waste and reduces costs associated with hosting an in-person meeting. The virtual meeting also provides opportunities to reduce carbon emissions related to travel for in-person meetings.

Any shareholder as of March 10, 2026 may participate in the Annual Meeting by logging in at virtualshareholdermeeting.com/CMS2026 for CMS shareholders and virtualshareholdermeeting.com/CMSPB2026 for Consumers shareholders. You must enter the control number found on your proxy card, voting instruction form or the Notice of Availability you previously received. If you misplaced your control number, or are not a shareholder, you may access the Annual Meeting by logging in as a guest, but you will not be able to vote, ask questions or inspect the list of shareholders.

We encourage you to log in to the Annual Meeting website and access the webcast early, beginning approximately 15 minutes before the Annual Meeting start time. If you experience technical difficulties, please contact the technical support telephone number on the Annual Meeting log-in page.

Shareholders may vote and submit proxies in advance of the Annual Meeting by one of the methods described in the Proxy Materials for the Annual Meeting or electronically vote during the Annual Meeting by following the instructions available on


CMS ENERGY 2026 PROXY STATEMENT			71

the applicable meeting website during the Annual Meeting. During the meeting, shareholder attendees will be able to inspect the list of shareholders.

How can I ask a question before or during the Annual Meeting?

Shareholders can ask questions prior to the meeting by visiting proxyvote.com. This allows all shareholders the opportunity to ask questions, regardless of whether they can attend the meeting and allows us to provide thoughtful responses to each question asked. Additionally, during the Annual Meeting, shareholder attendees will be able to submit questions. Responses to all appropriate questions will be posted on our website as soon as practicable after questions are received, addressed by Rochow during the Annual Meeting, and/or posted on our website no later than a week after the Annual Meeting.
