CMS Energy

CMS Energy was formed as a corporation in Michigan in 1987 and is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including Consumers, an electric and gas utility, and NorthStar Clean Energy, primarily a domestic independent power producer and marketer. Consumers’ customer base consists of a mix of primarily residential, commercial, and diversified industrial customers. NorthStar Clean Energy, through its subsidiaries and equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production.

CMS Energy manages its businesses by the nature of services each provides, and operates principally in three business segments: electric utility; gas utility; and NorthStar Clean Energy, its non‑utility operations and investments. Consumers’ consolidated operations account for the substantial majority of CMS Energy’s total assets, income, and operating revenue. CMS Energy’s consolidated operating revenue was $8.5 billion in 2025, and $7.5 billion in 2024 and 2023.

For further information about operating revenue, income, and assets and liabilities attributable to all of CMS Energy’s business segments and operations, see Item 8. Financial Statements and Supplementary Data—CMS Energy Consolidated Financial Statements and Notes to the Consolidated Financial Statements.

Business Segments

Consumers Electric Utility

Electric Utility Operations: Consumers’ electric utility operations, which include the generation, purchase, distribution, and sale of electricity, generated operating revenue of $5.6 billion in 2025, $5.1 billion in 2024, and $4.7 billion in 2023. Consumers’ electric utility customer base consists of a mix of primarily residential, commercial, and diversified industrial customers in Michigan’s Lower Peninsula.

Presented in the following illustration is Consumers’ 2025 electric utility operating revenue of $5.6 billion by customer class:

Consumers’ electric utility operations are not dependent on a single customer, or even a few customers, and the loss of any one or even a few of Consumers’ largest customers is not reasonably likely to have a material adverse effect on Consumers’ financial condition.

In 2025, Consumers’ electric deliveries were 37 billion kWh, which included ROA deliveries of 3 billion kWh, resulting in net bundled sales of 34 billion kWh. In 2024, Consumers’ electric deliveries were 37 billion kWh, which included ROA deliveries of 4 billion kWh, resulting in net bundled sales of 33 billion kWh.

Consumers’ electric utility operations are seasonal. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment.

Presented in the following illustration are Consumers’ monthly weather-normalized electric deliveries (deliveries adjusted to reflect normal weather conditions) to its customers, including ROA deliveries, during 2025 and 2024:

Consumers’ 2025 summer peak demand was 8,500 MW, which included ROA demand of 552 MW. For the 2024‑2025 winter season, Consumers’ peak demand was 5,755 MW, which included ROA demand of 449 MW. As required by MISO reserve margin requirements, Consumers owns or controls, through long‑term PPAs, short-term capacity purchases, and auction capacity purchases, all of the capacity required to supply its projected firm peak load and necessary reserve margin for summer 2026.

Electric Utility Properties: Consumers owns and operates electric generation and distribution facilities. For details about Consumers’ electric generation facilities, see the Electric Utility Generation and Supply Mix section that follows this Electric Utility Properties section. Consumers’ distribution system consists of:

• 263 miles of high-voltage distribution overhead lines operating at 138 kV
• 4 miles of high-voltage distribution underground lines operating at 138 kV
• 4,619 miles of high-voltage distribution overhead lines operating at 46 kV and 69 kV
• 18 miles of high-voltage distribution underground lines operating at 46 kV
• 82,854 miles of electric distribution overhead lines
• 10,027 miles of underground distribution lines
• 1,102 substations with an aggregate transformer capacity of 29 million kVA

Consumers is interconnected to the interstate high-voltage electric transmission system owned by METC and operated by MISO. Consumers is also interconnected to neighboring utilities and to other transmission systems.

Electric Utility Generation and Supply Mix: Consumers’ Electric Supply Plan, its long-term strategy for delivering safe, reliable, affordable, clean, and equitable energy to its customers, is outlined in its integrated resource plan and incorporates Consumers’ Renewable Energy Plan. The Electric Supply Plan is Consumers’ blueprint for compliance with Michigan’s 2023 Energy Law and for advancing sustainability objectives.

To meet these objectives, Consumers is executing a multi-faceted strategy. This strategy involves taking steps to end the use of coal, including the retirement of the D.E. Karn coal-fueled generating units, totaling 515 MW of nameplate capacity, in 2023 and obtaining MPSC approval to retire J.H. Campbell, totaling 1,407 MW of nameplate capacity. The retirement of J.H. Campbell is subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy. For a more detailed discussion of the emergency orders, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties—J.H. Campbell Emergency Orders and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

To continue providing controllable sources of electricity to customers, Consumers purchased the Covert Generating Station, representing 1,200 MW of nameplate capacity, in 2023 and has solicited additional capacity from controllable sources of electricity to customers.

Consumers’ updates to its Renewable Energy Plan include up to 9,000 MW of both purchased and owned solar energy resources and up to 4,000 MW of wind energy resources. Coupled with updates to its integrated resource plan, these actions position Consumers to achieve 60‑percent renewable energy by 2035 and 100‑percent clean energy by 2040. For further information on Consumers’ progress towards reducing carbon emissions and towards meeting the requirements of the 2023 Energy Law, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview and Outlook—Consumers Electric Utility Outlook and Uncertainties.

Presented in the following table are details about Consumers’ 2025 electric generation and supply mix:

1With the exception of wind and solar generation, the amount represents generation capacity during the summer months (planning year 2025 capacity as reported to MISO and limited by interconnection service limits). For wind and solar generation, the amount represents installed capacity.

2Consumers planned to retire these generating units in May 2025. However, the retirement of J.H. Campbell is subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy. Under those emergency orders, Consumers has continued to operate these units for the benefit of MISO’s North and Central regions. Of the 7,320 GWh generated by these units during 2025, Consumers supplied 3,608 GWh of electricity to MISO in order to comply with the emergency orders. For a more detailed discussion of the emergency orders, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties—J.H. Campbell Emergency Orders and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

2Represents purchases under long-term PPAs, including capacity purchases.

3Reflects net delivered energy from storage operations, after accounting for charging losses.

4Represents the net amount of generation offered to and purchased from the MISO energy market.

During 2025, 41 percent of Consumers’ electric supply was generated by its natural gas‑fueled generating units, which burned 105 Bcf of natural gas and produced a combined total of 14,661 GWh of electricity.

In order to obtain the gas it needs for electric generation fuel, Consumers’ electric utility purchases gas from the market near the time of consumption, at prices that allow it to compete in the electric wholesale market. For the Covert Generating Station and Jackson and Zeeland plants, Consumers utilizes an agent that owns firm transportation rights to each plant to purchase gas from the market and transport the gas to the facilities. For units 3 & 4 of D.E. Karn, Consumers holds gas transportation contracts to transport to the plant gas that Consumers or an agent purchase from the market.

During 2025, Consumers acquired 32 percent of its electric supply through long-term PPAs and the MISO energy market. Consumers offers its generation into the MISO energy market on a day-ahead and real‑time basis and bids for power in the market to serve the demand of its customers. Consumers supplements its generation capability with purchases from the MISO energy market.

At December 31, 2025, Consumers had future commitments to purchase capacity and energy under long‑term PPAs with various generating plants. These contracts require monthly capacity payments based on the plants’ availability or deliverability. The payments for 2026 through 2060 are estimated to total $17.0 billion and, for each of the next five years, range from $0.9 billion to $1.0 billion annually. These amounts may vary depending on plant availability and fuel costs. For further information about

Consumers’ future capacity and energy purchase obligations, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources and Liquidity—Other Material Cash Requirements and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments—Contractual Commitments.

During 2025, 20 percent of Consumers’ electric supply was generated by its coal-fueled generating units, which burned 4 million tons of coal and produced a combined total of 7,320 GWh of electricity. Consumers planned to exit coal generation in 2025 but the retirement of J.H. Campbell is subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy. Of the 7,320 GWh generated by these units during 2025, Consumers supplied 3,608 GWh of electricity to MISO in order to comply with the emergency orders. For a more detailed discussion of the emergency orders, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties—J.H. Campbell Emergency Orders and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

In order to obtain the coal it needs, Consumers has historically entered into physical coal supply contracts, leased a fleet of railcars, and secured transportation contracts with various companies to provide rail services for delivery of purchased coal to Consumers’ generating facilities. Following the emergency orders, Consumers was able to utilize relationships with existing suppliers in order to procure additional supply and maintain railcar leases and transportation contracts past the planned shutdown date of May 2025. At December 31, 2025, Consumers had future commitments to purchase and deliver coal for the remainder of the then-current emergency order, with options to extend these agreements if needed.

Electric Utility Competition: Consumers’ electric utility business is subject to actual and potential competition from many sources, in both the wholesale and retail markets, as well as in electric generation, electric delivery, and retail services.

Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at 10 percent of Consumers’ sales, with certain exceptions. At December 31, 2025, electric deliveries under the ROA program were at the 10‑percent limit. Fewer than 300 of Consumers’ electric customers purchased electric generation service under the ROA program. For additional information, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties.

Consumers also faces competition or potential competition associated with data center expansion and industrial customer relocation outside of Consumers’ service territory for economic reasons; municipalities owning or operating competing electric delivery systems; and customer self-generation. Consumers addresses this competition in various ways, including:

• aggressively controlling operating, maintenance, power supply, and fuel costs and passing savings on to customers
• providing renewable energy options and energy waste reduction programs
• providing competitive rate-design options, particularly for large energy-intensive customers
• offering tariff-based incentives that support economic development
• monitoring activity in adjacent geographical areas

Consumers Gas Utility

Gas Utility Operations: Consumers’ gas utility operations, which include the purchase, transmission, storage, distribution, and sale of natural gas, generated operating revenue of $2.5 billion in 2025, $2.1 billion in 2024, and $2.4 billion in 2023. Consumers’ gas utility customer base consists of a mix of primarily residential, commercial, and diversified industrial customers in Michigan’s Lower Peninsula.

Presented in the following illustration is Consumers’ 2025 gas utility operating revenue of $2.5 billion by customer class:

Consumers’ gas utility operations are not dependent on a single customer, or even a few customers, and the loss of any one or even a few of Consumers’ largest customers is not reasonably likely to have a material adverse effect on Consumers’ financial condition.

In 2025, deliveries of natural gas through Consumers’ pipeline and distribution network, including off‑system transportation deliveries, totaled 396 Bcf, which included GCC deliveries of 31 Bcf. In 2024, deliveries of natural gas through Consumers’ pipeline and distribution network, including off-system transportation deliveries, totaled 362 Bcf, which included GCC deliveries of 27 Bcf. Consumers’ gas utility operations are seasonal. The consumption of natural gas increases in the winter, due primarily to colder temperatures and the resulting use of natural gas as heating fuel. Consumers injects natural gas into storage during the summer months for use during the winter months. During 2025, 46 percent of the natural gas supplied to all customers during the winter months was supplied from storage.

Presented in the following illustration are Consumers’ monthly weather-normalized natural gas deliveries (deliveries adjusted to reflect normal weather conditions) to its customers, including GCC deliveries, during 2025 and 2024:

Gas Utility Properties: Consumers’ gas transmission, storage, and distribution system consists of:

• 2,337 miles of transmission lines
• 14 gas storage fields with a total storage capacity of 300 Bcf and a working gas volume of 153 Bcf
• 28,433 miles of distribution mains
• 8 compressor stations with a total of 147,393 installed and available horsepower

Under its Methane Reduction Plan, Consumers has set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent from 2012 baseline levels by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will likely be offset through clean fuel alternatives or nature-based carbon removal pathways.

Consumers has also set a goal to reduce customer greenhouse gas emissions by 25 percent by 2035. Consumers’ Natural Gas Delivery Plan, a rolling ten‑year investment plan to deliver safe, reliable, clean, and affordable natural gas to customers, outlines ways in which Consumers can make early progress toward these goals in a cost-effective manner, including energy waste reduction, carbon offsets, and renewable natural gas supply.

Consumers has already initiated work in these key areas by continuing to expand its energy waste reduction targets and by offering gas customers the ability to offset their carbon footprint associated with natural gas use by purchasing renewable natural gas and/or carbon credits associated with Michigan forest preservation. Consumers has renewable natural gas facilities under construction scheduled for commercial operation in 2026 and is monitoring regulatory developments and market conditions closely as part of its ongoing evaluation of the projects. For further information on Consumers’ progress towards its net-zero methane emissions goal, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.

Gas Utility Supply: In 2025, Consumers purchased 86 percent of the gas it delivered to its full-service sales customers. The remaining 14 percent was purchased from authorized GCC suppliers and delivered by Consumers to customers in the GCC program. Presented in the following illustration are the supply arrangements for the gas Consumers delivered to GCC and GCR customers during 2025:

Firm city-gate and firm gas transportation contracts are those that define a fixed amount, price, and delivery time frame. Consumers’ firm gas transportation contracts are with Panhandle Eastern Pipe Line Company and Trunkline Gas Company, LLC, each a non‑affiliated company. Under these contracts, Consumers purchases and transports gas to Michigan for ultimate delivery to its customers. Consumers’ firm gas transportation contracts expire on various dates through 2028 with planned contract volumes providing 34 percent of Consumers’ total forecasted gas supply requirements for 2026. Consumers purchases the balance of its required gas supply under firm city-gate contracts and through authorized suppliers under the GCC program.

Gas Utility Competition: Competition exists in various aspects of Consumers’ gas utility business. Competition comes from GCC and transportation programs; system bypass by new and existing customers; and from alternative fuels and energy sources, such as propane, oil, and electricity.

NorthStar Clean Energy—Non-utility Operations and Investments

NorthStar Clean Energy, through various subsidiaries and certain equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production. NorthStar Clean Energy’s operating revenue was $408 million in 2025, $316 million in 2024, and $297 million in 2023.

Energy Resource Management: CMS ERM purchases and sells energy commodities in support of NorthStar Clean Energy’s generating facilities with a focus on optimizing the independent power production portfolio. In 2025, CMS ERM marketed 2 Bcf of natural gas and 7,625 GWh of electricity. Electricity marketed by CMS ERM was generated by independent power production of NorthStar Clean

Energy and by unrelated third parties. CMS ERM’s operating revenue was $331 million in 2025, $247 million in 2024, and $233 million in 2023.

NorthStar Clean Energy Competition: NorthStar Clean Energy competes with other energy developers, energy retailers, and independent power producers. The needs of this market are driven by current electric demand and available generation, as well as projections of future electric demand and available generation.

CMS Energy and Consumers Regulation

CMS Energy, Consumers, and their subsidiaries are subject to regulation by various federal, state, and local governmental agencies, including those described in the following sections. Rate proceedings and other regulatory actions may affect operations and financial results. If CMS Energy, Consumers, or their subsidiaries failed to comply with applicable laws and regulations, they could become subject to fines, penalties, or disallowed costs, or be required to implement additional compliance, cleanup, or remediation programs, the cost of which could be material. For more information on the potential impacts of government regulation and rate proceedings affecting CMS Energy, Consumers, and their subsidiaries, see Item 1A. Risk Factors, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook, and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

FERC and NERC

CMS Energy and its affiliates and subsidiaries are subject to regulation by FERC in a number of areas. FERC regulates certain aspects of Consumers’ electric business, including, but not limited to, compliance with FERC accounting rules, wholesale electric and transmission rates, operation of licensed hydroelectric generating plants, corporate mergers and the sale and purchase of certain assets, issuance of securities, and conduct among affiliates. FERC also regulates the tariff rules and procedures administered by MISO and other independent system operators/regional transmission organizations, including rules governing wholesale electric markets and interconnection of new generating facilities to the transmission system. FERC, in connection with NERC and with regional reliability organizations, also regulates generation and transmission owners and operators, load-serving entities, and others with regard to reliability of the bulk power system.

FERC also regulates limited aspects of Consumers’ gas business, principally compliance with FERC capacity release rules, shipping rules, the prohibition of certain buy/sell transactions, and the price-reporting rule.

FERC also regulates holding company matters, interlocking directorates, and other issues affecting CMS Energy. In addition, similar to FERC’s regulation of Consumers’ electric and gas businesses, FERC has jurisdiction over several independent power plants, PURPA-qualifying facilities, and exempt wholesale generators in which NorthStar Clean Energy has ownership interests, as well as over NorthStar Clean Energy itself, CMS ERM, CMS Gas Transmission, and DIG.

MPSC

Consumers is subject to the jurisdiction of the MPSC, which regulates public utilities in Michigan with respect to retail utility rates, accounting, utility services, certain facilities, certain asset transfers, corporate mergers, and other matters.

The Michigan Attorney General, ABATE, the MPSC Staff, residential customer advocacy groups, environmental organizations, and certain other parties typically participate in MPSC proceedings concerning Consumers. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC and FERC orders.

Other Regulation

The U.S. Secretary of Energy regulates imports and exports of natural gas and has delegated various aspects of this jurisdiction to FERC and the DOE’s Office of Fossil Fuels. Additionally, the U.S. Secretary of Energy has the authority to issue emergency orders for power plants under section 202(c) of the Federal Power Act. This provision allows the U.S. Secretary of Energy to temporarily alter the operation of the electricity system during emergencies.

The U.S. Department of Transportation’s Office of Pipeline Safety regulates the safety and security of gas pipelines through the Natural Gas Pipeline Safety Act of 1968 and subsequent laws.

The Transportation Security Administration, an agency of the U.S. Department of Homeland Security, regulates certain activities related to the safety and security of natural gas pipelines.

Energy Legislation

In 2023, Michigan enacted the 2023 Energy Law, which among other things:

• increased the renewable energy standard from 15 percent to 50 percent by 2030 and 60 percent by 2035; renewable energy generated anywhere within MISO can be applied to meeting this standard, with certain limitations
• established a clean energy standard of 80 percent by 2035 and 100 percent by 2040; low- or zero‑carbon emitting resources, such as nuclear generation and natural gas generation coupled with carbon capture, qualify as clean energy sources under this standard
• authorized the MPSC to grant extensions of the clean energy or renewable energy standards deadlines if compliance is not practically feasible, would be excessively costly to customers, or would cause reliability issues
• increased the energy waste reduction requirement for electric utilities to achieve annual reductions in customers’ electricity use from the present 1‑percent reduction requirement to 1.5 percent beginning in 2026; beyond this requirement, the law set a goal of a 2‑percent reduction and required that such goal be incorporated in an electric utility’s integrated resource plan modeling scenarios
• increased the energy waste reduction requirement for gas utilities to achieve annual reductions in customers’ gas use from the present 0.75‑percent reduction requirement to 0.875 percent beginning in 2026
• enhanced existing incentives for energy efficiency programs and returns earned on new clean or renewable PPAs
• created a new energy storage standard, requiring electric utilities to file plans by 2029 to help achieve a statewide target of 2,500 MW
• expanded the statutory cap on distributed generation resources to 10 percent of the electric utility’s five‑year average peak load
• expanded the MPSC’s scope of considerations in integrated resource plans to include affordability, greenhouse gas emissions, environmental justice considerations, the effects on human health, and other environmental concerns
• provided the MPSC siting authority over large renewable energy projects

Consumers’ updates to its Renewable Energy Plan, which were approved by the MPSC in September 2025, and planned updates to its integrated resource plan in 2026 will serve as a blueprint to meeting the requirements of the 2023 Energy Law by focusing on increasing the generation of renewable energy, deploying energy storage, helping customers use less energy, and offering demand response programs to reduce demand during critical peak times.

CMS Energy and Consumers Environmental Strategy and Compliance

CMS Energy and Consumers are committed to protecting the environment; this commitment extends beyond compliance with applicable laws and regulations. Consumers’ Electric Supply Plan, its long-term strategy for delivering safe, reliable, affordable, clean, and equitable energy to its customers, is outlined in its integrated resource plan and incorporates Consumers’ Renewable Energy Plan. The Electric Supply Plan is Consumers’ blueprint for compliance with Michigan’s 2023 Energy Law and for advancing sustainability objectives. This plan positions Consumers to achieve 60‑percent renewable energy by 2035 and 100‑percent clean energy by 2040.

Under its Methane Reduction Plan, Consumers has set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent from 2012 baseline levels by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will likely be offset through clean fuel alternatives or nature-based carbon removal pathways. For additional information on Consumers’ Methane Reduction Plan, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Gas Utility Outlook and Uncertainties—Gas Environmental Outlook.

Consumers has also set a goal to reduce customer greenhouse gas emissions by 25 percent by 2035. Consumers expects to meet this goal through carbon offset measures, renewable natural gas, energy efficiency and demand response programs, and the adoption of cost-effective emerging technologies once proven and commercially available.

CMS Energy’s and Consumers’ commitment to protecting the environment extends to advancing the principles of environmental justice in current and future operations. These principles center on protecting communities impacted by the companies’ operations, especially those communities that are most vulnerable and may have suffered disparate impacts of environmental harm.

Advancing environmental justice comes in a variety of forms. For example, Consumers has conducted an environmental justice analysis to help understand the environmental impacts of its clean energy transformation. Similarly, Consumers is using an environmental justice screening tool provided by the State of Michigan in the planning of improvements to the electric and gas distribution system, including prioritizing investments in more vulnerable communities.

A core tenet of environmental justice is inviting the input of the stakeholders in the local communities where CMS Energy and Consumers operate and invest. The companies are committed to maintaining a transparent dialogue when developing projects, whether in new or existing areas of operation.

CMS Energy, Consumers, and their subsidiaries are subject to various federal, state, and local environmental regulations for solid waste management, air and water quality, and other matters. Consumers expects to recover costs to comply with environmental regulations in customer rates but cannot guarantee this result. For additional information concerning environmental matters, see Item 1A. Risk Factors, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of

Operations—Outlook, and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments.

CMS Energy has recorded a $48 million liability for its subsidiaries’ obligations associated with Bay Harbor and Consumers has recorded a $59 million liability for its obligations at a number of former MGP sites. For additional information, see Item 1A. Risk Factors and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments.

Costs related to the construction, operation, corrective action, and closure of solid waste disposal facilities for coal ash are significant. Consumers’ coal ash disposal areas are regulated under Michigan’s solid waste rules and by the EPA’s rules regulating CCRs. To address some of the requirements of these rules, Consumers has converted all of its fly ash handling systems to dry conveyance systems. In addition, Consumers’ ash facilities have programs designed to protect the environment and are subject to quarterly EGLE inspections. Consumers’ estimate of capital and cost of removal expenditures to comply with regulations relating to ash disposal is $241 million from 2026 through 2030. Consumers’ future costs to comply with solid waste disposal regulations may vary depending on future legislation, litigation, executive orders, treaties, or rulemaking. These costs may further increase if additional emergency orders necessitate continued operation of the J.H. Campbell plant beyond current expectations. Consumers intends to request recovery of any incremental costs through its ongoing cases before FERC. For additional information, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

For further information concerning estimated capital expenditures related to environmental matters, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook—Consumers Electric Utility Outlook and Uncertainties—Electric Environmental Outlook.

Insurance

CMS Energy and its subsidiaries, including Consumers, maintain insurance coverage generally similar to comparable companies in the same lines of business. The insurance policies are subject to terms, conditions, limitations, and exclusions that might not fully compensate CMS Energy or Consumers for all losses. A portion of each loss is generally assumed by CMS Energy or Consumers in the form of deductibles and self-insured retentions that, in some cases, are substantial. As CMS Energy or Consumers renews its policies, it is possible that some of the present insurance coverage may not be renewed or obtainable on commercially reasonable terms due to restrictive insurance markets.

Human Capital

CMS Energy and Consumers employ a highly trained and skilled workforce comprised of union and non‑union employees. Presented in the following table are the number of employees of CMS Energy and Consumers:

At December 31, 2025, unions represented 44 percent of CMS Energy’s employees and 45 percent of Consumers’ employees. The UWUA represents Consumers’ and NorthStar Clean Energy’s operating, maintenance, construction employees and Consumers’ customer contact center employees. The USW represents Consumers’ Zeeland plant employees. Consumers’ union agreements expire in 2030 and the majority of NorthStar Clean Energy’s represented employees have an agreement that expires in 2029.

The safety of co-workers, customers, and the general public is a priority of CMS Energy and Consumers. Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture. These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions. On an annual basis, CMS Energy and Consumers set various safety goals tied to the OSHA recordable incident rate and to high-risk injuries. The companies’ OSHA recordable incident rate was 2.34 in 2025 and 1.71 in 2024. High-risk injuries encompass all recordable and non-recordable incidents with the potential for serious injury or fatality. In 2025, the companies recorded nine high-risk injuries, achieving their goal of less than 12 high-risk injuries. Beginning in 2026, the companies will utilize the serious injury incidence rate to measure and set safety goals. The target serious injury incidence rate for 2026 is 0.037, which, if achieved, would place Consumers within the second quartile of its EEI peer group.

Within the utility industry, there is strong competition for rare, high-demand talent, including those related to electric line work, renewable energy generation, technology, and data analytics. In order to address this competition and to be able to meet their human capital needs, CMS Energy and Consumers provide compensation and benefits that are competitive with industry peers. Furthermore, CMS Energy and Consumers have developed a comprehensive talent strategy, the People Strategy, to attract, develop, and retain highly skilled co-workers. The strategy focuses on three areas, which are summarized below. The first two areas listed below focus on creating an environment that attracts and retains top talent and ensuring that all co-workers can thrive and contribute to the companies’ mission and purpose.

• Cultivating a Purpose-driven Culture: This goal aims to ensure all co-workers understand how their work contributes to CMS Energy’s and Consumers’ key strategic goals.
• Creating a Breakthrough Employee Experience: A breakthrough employee experience is one that instills pride and ownership in one’s work. To measure progress toward a breakthrough employee experience, CMS Energy and Consumers assess engagement, empowerment, and

diversity, equity, and inclusion efforts using the companies’ culture index. For the year ended December 31, 2025, the companies attained scores of:

• 75‑percent positive sentiment for engagement, up 3 percentage points from 2024
• 65‑percent positive sentiment for empowerment, no change from 2024
• 75‑percent positive sentiment for diversity, equity, and inclusion, up 2 percentage points from 2024

CMS Energy and Consumers aim to continuously improve these scores every year.

• Building Skill Sets at Scale: With an overarching goal of ensuring co-workers have the right skills to succeed, CMS Energy and Consumers measure progress in this area through achievement of workforce planning and hiring milestones and through a first-time skill attainment index to evaluate the effectiveness of training. CMS Energy and Consumers develop skill sets in co‑workers through a variety of means, including union apprenticeship programs and yearly trainings for newly required skills.

This talent strategy allows CMS Energy and Consumers to shape co-workers’ experience and enable leaders to coach and develop co‑workers, source talent, and anticipate and adjust to changing skill sets in the business environment.

Diversity, Equity, and Inclusion

As a part of their People Strategy, CMS Energy and Consumers employ a broad and holistic diversity, equity, and inclusion strategy focused on embracing differences and creating a sense of belonging for all co-workers. The strategy is aimed at integrating principles of equity and inclusion into every process and co‑worker experience. To measure their success, CMS Energy and Consumers utilize select questions in the annual engagement survey to create a diversity, equity, and inclusion index. For the year ended December 31, 2025, the diversity, equity, and inclusion index score was 75 percent.

CMS Energy and Consumers are committed to building an inclusive workplace that embraces the diverse makeup of the communities that they serve. The following table presents the composition of CMS Energy’s and Consumers’ workforce:

35

Co‑workers are also empowered to engage in business employee resource groups and events that encourage candid conversations around diversity, equity, and inclusion. These activities enhance personal growth, build stronger connections among co-workers, and contribute to a more inclusive workplace. There are eight business employee resource groups available to all co‑workers; these groups are:

• Women in Energy, working toward an inclusive place for all women in the fields they have chosen, from front line to management
• the Minority Advisory Panel, promoting a culture of diversity and inclusion among all racial and ethnic minorities through education, leadership, development, and networking
• the Veterans Advisory Panel, supporting former and active military personnel and assisting in recruiting and retaining veterans through career development
• Genergy, a multigenerational group designed to bridge the gap of learning, networking, and mentoring across the generations of the workforce
• the Pride Alliance of CMS Energy, promoting an inclusive environment that is safe, supportive, and respectful for lesbian, gay, bi-sexual, and transgender persons and allies
• Capable, aimed at removing barriers and creating pathways to meaningful work for co-workers of all abilities
• Interfaith, a space for co‑workers of all backgrounds to gather and celebrate their unique beliefs, creating an environment of understanding and respect for all faiths, religions, and spiritual beliefs, including those with no faith affiliation
• People and Planet Partners, empowering co-workers to drive social benefits for customers and communities and advance environmental improvements, reduce the companies’ environmental footprint, and support the companies’ planet goals

CMS Energy and Consumers are exposed to a variety of factors, often beyond their control, that are difficult to predict and that involve uncertainties that may materially adversely affect CMS Energy’s or Consumers’ business, liquidity, financial condition, or results of operations. Additional risks and uncertainties not presently known or that management believes to be immaterial may also adversely affect CMS Energy or Consumers. The risk factors described in the following sections, as well as the other information included in this report and in other documents filed with the SEC, should be considered carefully before making an investment in securities of CMS Energy or Consumers. Risk factors of Consumers are also risk factors of CMS Energy.

Investment/Financial Risks

CMS Energy depends on dividends from its subsidiaries to meet its debt service obligations.

Due to its holding company structure, CMS Energy depends on dividends from its subsidiaries to meet its debt service and other payment obligations. If sufficient dividends were not paid to CMS Energy by its subsidiaries, CMS Energy might not be able to generate the funds necessary to fulfill its payment obligations.

Consumers’ ability to pay dividends or acquire its own stock from CMS Energy is limited by restrictions contained in Consumers’ preferred stock provisions and potentially by other legal restrictions, such as certain terms in its articles of incorporation and FERC requirements.

CMS Energy has indebtedness that could limit its financial flexibility and its ability to meet its debt service obligations.

The level of CMS Energy’s present and future indebtedness could have several important effects on its future operations, including, among others, that:

• a significant portion of CMS Energy’s cash flow from operations could be dedicated to the payment of principal and interest on its indebtedness and would not be available for other purposes
• covenants contained in CMS Energy’s existing debt arrangements, which require it to meet certain financial tests, could affect its flexibility in planning for, and reacting to, changes in its business
• CMS Energy’s ability to obtain additional financing for working capital, capital expenditures, acquisitions, and general corporate and other purposes could become limited
• CMS Energy could be placed at a competitive disadvantage to its competitors that are less leveraged
• CMS Energy’s vulnerability to adverse economic and industry conditions could increase
• CMS Energy’s future credit ratings could fluctuate

CMS Energy’s ability to meet its debt service obligations and to reduce its total indebtedness will depend on its future performance, which will be subject to general economic conditions, industry cycles, changes in laws or regulatory decisions, and financial, business, and other factors affecting its operations, many of which are beyond its control. CMS Energy cannot make assurances that its businesses will continue to generate sufficient cash flow from operations to service its indebtedness, which could require CMS Energy to sell assets or obtain additional financing.

CMS Energy and Consumers have financing needs and could be unable to obtain bank financing or access the capital markets.

CMS Energy and Consumers rely on the capital markets, as well as on bank syndications, to meet their financial commitments and short-term liquidity needs not otherwise funded internally.

Disruptions in the capital and credit markets, or the inability to obtain required regulatory authorization for issuances of securities including debt, including as may be required from FERC, could adversely affect CMS Energy’s and Consumers’ access to liquidity needed for their businesses. Any liquidity disruption could require CMS Energy and Consumers to take measures to conserve cash including, but not limited to, deferring capital expenditures, changing commodity purchasing strategies to avoid collateral-posting requirements, and reducing or eliminating future share repurchases, dividend payments, or other discretionary uses of cash.

Entering into new financings is subject in part to capital market receptivity to utility industry securities in general and to CMS Energy’s and Consumers’ securities in particular. CMS Energy and Consumers continue to explore financing opportunities to supplement their respective financial strategies. These potential opportunities include refinancing and/or issuing new debt, issuing CMS Energy preferred stock and/or common equity, or entering into commercial paper, bank financing, and leasing arrangements. CMS Energy and Consumers cannot guarantee the capital markets’ acceptance of their securities. CMS Energy and Consumers may also, from time to time, repurchase (either in open market transactions or through privately negotiated transactions), redeem, or otherwise retire outstanding debt. Such activities, if any, will depend on prevailing market conditions, contractual restrictions, and other factors. The amounts involved may or may not be material.

Certain of CMS Energy’s and Consumers’ securities and those of their affiliates are rated by various credit rating agencies. A reduction or withdrawal of one or more of its credit ratings could have a material adverse impact on CMS Energy’s or Consumers’ ability to access capital on acceptable terms and maintain commodity lines of credit, could increase their cost of borrowing, and could cause CMS Energy or Consumers to reduce capital expenditures. If either or both were unable to maintain commodity lines of credit, CMS Energy or Consumers might have to post collateral or make prepayments to certain suppliers under existing contracts. Further, since Consumers provides dividends to CMS Energy, any adverse developments affecting Consumers that result in a lowering of its credit ratings could have an adverse effect on CMS Energy’s credit ratings.

Market performance and other changes could decrease the value of employee benefit plan assets, which then could require substantial funding.

The performance of various markets affects the value of assets that are held in trust to satisfy future obligations under CMS Energy’s and Consumers’ pension and postretirement benefit plans. CMS Energy and Consumers have significant obligations under these plans and hold significant assets in these trusts. These assets are subject to market fluctuations and will yield uncertain returns, which could fall below CMS Energy’s and Consumers’ forecasted return rates. A decline in the market value of the assets or a change in the level of interest rates used to measure the required minimum funding levels could significantly increase the funding requirements of these obligations. Also, changes in demographics, including an increased number of retirements or changes in life expectancy assumptions, could significantly increase the funding requirements of the obligations related to the pension and postretirement benefit plans.

Industry/Regulatory Risks

Changes to ROA could have a material adverse effect on CMS Energy’s and Consumers’ businesses.

Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at 10 percent of Consumers’ sales, with certain exceptions. The proportion of Consumers’ electric deliveries under the ROA program and on the ROA waiting list is over 10 percent. Consumers’ rates are regulated by the MPSC, while alternative electric suppliers charge market-based rates, putting competitive pressure on Consumers’ electric supply. Groups are advocating for an ROA-like community solar program that allows third parties to sell directly to customers and offer them a regulated bill credit. If the amount of ROA sales increased, this new ROA‑like community solar program were allowed, or electric generation service in Michigan were further deregulated, it could have a material adverse effect on CMS Energy and Consumers.

FERC issued an advance notice of proposed rulemaking in response to the Secretary of the DOE’s direction to FERC to consider the advance notice of proposed rulemaking as a means to standardize and expedite interconnection procedures and agreements for large electric loads. If FERC asserts jurisdiction over the distribution components of large-load customers’ interconnections to the transmission system, or allows large-load customers to directly purchase electricity from wholesale markets, it could have a material adverse effect on CMS Energy and Consumers.

The creation of utilities by municipalities in Consumers’ service territory, or the impairment of Consumers’ franchise rights to serve customers in municipalities, could have a material adverse effect on CMS Energy’s and Consumers’ businesses.

Michigan law allows Consumers’ electric and natural gas utility businesses to serve customers pursuant to franchises granted by municipalities. Michigan law also allows municipalities to create, own, and operate utilities. If one or more municipalities in Consumers’ service territory created a new or supplemental utility, or impaired the franchise under which Consumers serves customers in the municipality, it could have a material adverse effect on CMS Energy and Consumers.

Distributed energy resources could have a material adverse effect on CMS Energy’s and Consumers’ businesses.

Michigan law allows customers to use distributed energy resources for their electric energy needs. These distributed energy resources are connected to Consumers’ electric grid. The 2023 Energy Law increases the cap on Consumers’ distributed generation program to 10 percent of utilities’ peak loads. It also specifies an inflow and outflow rate method that must be implemented by the MPSC. FERC policy allows many customer-owned behind-the-meter and grid-connected distributed energy resources to participate in and receive revenue from wholesale electricity markets, as governed by evolving wholesale market rules subject to FERC oversight. Increased customer use of distributed energy resources could result in a reduction of Consumers’ electric sales. Third parties’ operations of distributed energy resources could also potentially have a negative impact on the stability of the grid. An increase in customers’ use of distributed energy resources, and the rate structure for distributed energy resources customers’ use of Consumers’ system and Consumers’ purchases of their excess generation, could have a material adverse effect on CMS Energy and Consumers.

CMS Energy and Consumers are subject to rate regulation, which could have a material adverse effect on financial results.

CMS Energy and Consumers are subject to rate regulation. Consumers’ electric and gas retail rates are set by the MPSC and cannot be changed without regulatory authorization. If rate regulators fail to provide adequate rate relief, it could have a material adverse effect on Consumers or Consumers’ plans for making significant capital investments. Additionally, increasing rates could result in additional regulatory scrutiny, regulatory or legislative actions, and increased competitive or political pressures, all of which could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations.

Orders of the MPSC could limit recovery of costs of providing service. These orders could also result in adverse regulatory treatment of other matters. For example, MPSC orders could prevent or curtail Consumers from shutting off non‑paying customers, could prevent or limit the implementation of an electric or gas revenue mechanism, or could penalize Consumers for not meeting service and reliability standards. Regulators could face competitive or political pressures to avoid or limit rate increases for a number of reasons, including affordability concerns, economic downturn, reliability and economic justice concerns, or decreased customer base, among others.

FERC authorizes certain subsidiaries of CMS Energy, including Consumers, to sell wholesale electricity at market-based rates and to provide certain other wholesale electric services at rates and terms subject to FERC approval. Failure of these subsidiaries to maintain this FERC authority could have a material adverse effect on CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Electric transmission and natural gas pipeline rates paid by Consumers and other CMS Energy subsidiaries are also set by FERC, as are the tariff terms governing the participation of Consumers and other CMS Energy subsidiaries in FERC-regulated wholesale electricity markets operated by regional transmission organizations and independent system operators such as MISO and PJM. At least one CMS Energy subsidiary participates in the wholesale electricity markets operated by ERCOT, over which FERC has limited control.

Consumers also faces regulatory uncertainty resulting from the U.S. Secretary of Energy’s emergency orders issued under the Federal Power Act and associated DOE regulations, which direct continued operation of the J.H. Campbell, as well as similar prior or future executive actions, including the January 2025 and April 2025 executive orders related to energy supply and reliability. The Federal Power Act, DOE regulations, and U.S. Secretary of Energy emergency orders all provide for cost recovery associated with continued operations, but there is not currently a FERC-approved MISO Tariff for recovery of compliance costs associated with the continued operation of J.H. Campbell, and continued operation of J.H. Campbell is not contemplated in Consumers’ current MPSC rates or rate filings at the MPSC. Consumers is pursuing cost recovery at FERC but cannot predict the outcome of those efforts or the impact of other executive actions.

The various risks associated with the MPSC and FERC regulation of CMS Energy’s and Consumers’ businesses, which include the risk of adverse decisions in any number of rate or regulatory proceedings before either agency, as well as judicial proceedings challenging any agency decisions, could have a material adverse effect on CMS Energy and Consumers. Changes to the tariffs or business practice manuals of certain wholesale market operators such as MISO, PJM, or ERCOT, or corresponding impacts such as interconnection delays for new electric generation or storage projects, could also have a material adverse effect on CMS Energy and Consumers.

Utility regulation, state or federal legislation, regulation, and compliance could have a material adverse effect on CMS Energy’s and Consumers’ businesses.

CMS Energy and certain of its subsidiaries, including Consumers, are subject to, or affected by, extensive utility regulation and state and federal legislation and regulation, including through application of policies and rules of numerous state and federal agencies and governmental entities. If it were determined that CMS Energy or Consumers failed to comply with applicable laws and regulations or with applicable tariff provisions, they could become subject to fines, penalties, refund or disgorgement orders, or disallowed costs, or be required to implement additional compliance, cleanup, or remediation programs, the cost of which could be material. CMS Energy and Consumers cannot predict the impact of new laws, rules, regulations, tariffs, principles, orders, or practices by federal or state agencies or wholesale electricity market operators, or challenges or changes to present laws, rules, regulations, tariffs, principles, orders, or practices and the interpretation of any adoption or change. Furthermore, any state or federal legislation, regulation, order, or other action concerning CMS Energy’s or Consumers’ operations could also have a material adverse effect.

FERC, through NERC and its delegated regional entities, oversees reliability of certain portions of the electric grid. CMS Energy and Consumers cannot predict the impact of the DOE or FERC orders or actions of NERC and its regional entities on electric system reliability. Additionally, natural gas pipeline infrastructure has recently been under scrutiny following disruptions related to extreme weather and cyber incidents. Additional regulation in this area could adversely affect Consumers’ gas operations.

CMS Energy and Consumers have announced ambitious plans to reduce their impact on climate change and increase the reliability of their electric distribution system. Achieving these plans depends on numerous factors, many of which are outside of their control.

Consumers has announced a long-term strategy for delivering clean, reliable, resilient, and affordable energy, and other subsidiaries of CMS Energy have plans to develop and operate clean energy assets. The MPSC, FERC, other regulatory authorities, or other third parties may prohibit, delay, or impair some or all of CMS Energy’s and Consumers’ planned acquisitions or development of owned or purchased electric generation and storage capacity. Consumers’ planned electric generation capacity, including renewable generation or storage projects, may be adversely impacted by interconnection delays at MISO or in the footprints of other regional transmission organizations, and/or by interconnection costs. CMS Energy and Consumers and its contractors may be unable to acquire, site, construct timely, and/or permit generation and storage capacity, including some or all of the generation and storage capacity proposed in Consumers’ plan. CMS Energy and Consumers’ ability to implement their plans may be affected by environmental regulations, global supply chain disruptions, import tariffs, and changes in the cost, availability, and supply of generation and storage capacity. While CMS Energy and Consumers continue to advocate for advances in commercially available technologies required to reduce or eliminate greenhouse gases on a cost-effective basis at scale, such advances are largely outside of CMS Energy’s and Consumers’ control. Advancements in technology related to items such as battery storage, carbon capture/storage, and electric vehicles may not become commercially available or economically feasible as projected. Customer programs such as energy efficiency and demand response may not realize the projected levels of customer participation.

Consumers has also announced its electric Reliability Roadmap. The Reliability Roadmap includes larger investments in grid hardening, distribution capacity, and automation to deliver better than median reliability to customers given increasingly severe weather and customer adoption of new technologies. The MPSC or other third parties may prohibit, delay, or impair the Reliability Roadmap and some or all of the associated capital investments. Consumers’ ability to implement its plan may be affected by global supply chain disruptions and/or workforce availability.

Consumers has also announced its Natural Gas Delivery Plan, a rolling ten‑year investment plan to deliver safe, reliable, clean, and affordable natural gas to customers. This plan includes accelerated infrastructure replacements, innovative leak detection technology, and process changes to reduce or eliminate methane emissions. The MPSC, FERC, U.S. Department of Transportation, other regulatory authorities, or other third parties may prohibit, delay, or impair the Natural Gas Delivery Plan and some or all of the associated capital investments. Consumers’ ability to implement its plan may be affected by environmental regulations, global supply chain disruptions, import tariffs, and changes in the cost, availability, and supply of natural gas or the ability to deliver natural gas to customers. Advancements in technology related to items such as renewable natural gas may not become commercially available or economically feasible as projected in Consumers’ plan.

CMS Energy and Consumers could suffer financial loss, reputational damage, litigation, or other negative repercussions if they are unable to achieve their ambitious plans.

Changes in taxation as well as the inherent difficulty in quantifying potential tax effects of business decisions could negatively impact CMS Energy and Consumers.

CMS Energy and Consumers are required to make judgments regarding the potential tax effects of various financial transactions and results of operations in order to estimate their obligations to taxing authorities. The tax obligations include income taxes, real estate taxes, sales and use taxes, employment-related taxes, and ongoing issues related to these tax matters. The judgments include determining reserves for potential adverse outcomes regarding tax positions that have been taken and may be subject to challenge by the IRS and/or other taxing authorities. Unfavorable settlements of any of the issues related to these reserves or other tax matters at CMS Energy or Consumers could have a material adverse effect. Additionally, changes in federal, state, or local tax rates or other changes in tax laws could have adverse impacts. In July 2025, President Trump signed the OBBBA into law. CMS Energy and Consumers evaluated the provisions of the OBBBA and concluded that the legislation is not expected to have a material impact on their respective financial statements. This conclusion is subject to change as additional guidance or interpretations become available.

CMS Energy and its subsidiaries, including Consumers, must comply with the Dodd-Frank Act and its related regulations.

The Dodd-Frank Act provides for regulation by the Commodity Futures Trading Commission of certain commodity-related contracts. Although CMS Energy, Consumers, and certain subsidiaries of NorthStar Clean Energy qualify for an end-user exception from mandatory clearing of commodity-related swaps, these regulations could affect the ability of these entities to participate in these markets and could add additional regulatory oversight over their contracting activities.

CMS Energy and Consumers could incur substantial costs to comply with environmental requirements.

CMS Energy and Consumers are subject to costly and stringent environmental regulations that may require additional significant capital expenditures for CCR disposal and storage, emission reductions, and PCB remediation. In addition, regulatory action on PFAS at the state and/or federal level could cause CMS Energy and Consumers to further test and remediate some sites if PFAS is present at certain levels. Present and reasonably anticipated state and federal environmental statutes and regulations will continue to have a material effect on CMS Energy and Consumers.

CMS Energy and Consumers have interests in fossil-fuel-fired power plants, other types of power plants, and natural gas systems that emit greenhouse gases. Federal, state, and local environmental laws, regulations and orders, as well as international accords and treaties, could require CMS Energy and Consumers to install additional equipment for emission controls, undertake heat-rate improvement projects, purchase carbon emissions allowances, curtail or extend operations, invest in generating capacity with fewer carbon dioxide emissions, or take other significant steps to manage or lower the emission of greenhouse gases. Similarly, Consumers could be restricted from constructing natural gas infrastructure due to potential environmental regulations, which could require more costly alternatives.

The following risks related to climate change, emissions, and environmental regulations could also have a material adverse impact on CMS Energy and Consumers:

• a change in policy/regulation, regulators’ implementation of policy/regulation or litigation originated by third parties against CMS Energy or Consumers due to CMS Energy’s or Consumers’ greenhouse gas or other emissions or CCR disposal and storage
• impairment of CMS Energy’s or Consumers’ reputation due to their greenhouse gas or other emissions and public perception of their response to potential environmental regulations, rules, orders, and legislation
• weather that may affect customer demand, company operations, or company infrastructure, including catastrophic weather-related damage and extreme temperatures; natural disasters such as severe storms, floods, and droughts; fires; or smoke
• implementation of state or federal environmental justice requirements

Consumers expects to collect fully from its customers, through the ratemaking process, expenditures incurred to comply with environmental regulations, but cannot guarantee this outcome. There is not currently a FERC-approved MISO Tariff for recovery of compliance costs associated with the continued operation of J.H. Campbell, and continued operation of J.H. Campbell is not contemplated in Consumers’ current MPSC rates or rate filings at the MPSC. Consumers is pursuing cost recovery at FERC but cannot predict the outcome of those efforts or the impact of other executive actions. If Consumers were unable to recover these expenditures from customers in rates, CMS Energy or Consumers could be required to seek significant additional financing to fund these expenditures.

For additional information regarding compliance with environmental regulations, see Item 1. Business—CMS Energy and Consumers Environmental Strategy and Compliance and Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Outlook.

CMS Energy’s and Consumers’ businesses could be affected adversely by any delay in meeting environmental requirements.

A delay or failure by CMS Energy or Consumers to obtain or maintain any necessary environmental permits or approvals to satisfy any applicable environmental regulatory requirements or install emission or pollution control equipment could:

• prevent the construction of new facilities
• prevent the continued operation of and sale of energy from existing facilities
• modify the way in which a facility is operated
• prevent the suspension of operations at existing facilities
• prevent the modification of existing facilities
• result in significant additional costs, including fines or penalties

CMS Energy and Consumers expect to incur additional substantial costs related to environmental remediation of former sites.

Consumers expects to incur additional substantial costs related to the remediation of its former MGP sites and other response activity costs at a number of other former sites, including, but not limited to, sites of retired coal-fueled electric generating units and sites containing coal ash and related materials, under NREPA, RCRA, CERCLA and related state and federal regulations. Consumers believes these costs should be recoverable in rates but cannot guarantee that outcome.

Business/Operations Risks

There are risks associated with Consumers’ substantial capital investment program planned for the next five years.

Consumers’ planned investments include the construction or acquisition of electric generation, electric and gas infrastructure, conversions and expansions, environmental controls, electric grid automation technologies, and other electric and gas investments to upgrade delivery systems, as well as decommissioning of older facilities. The success of these capital investments depends on or could be affected by a variety of factors that include, but are not limited to:

• effective pre-acquisition evaluation of asset values, future operating costs, potential environmental and other liabilities, and other factors beyond Consumers’ control
• effective cost and schedule management of new capital projects
• availability of qualified construction personnel, both internal and contracted
• effective and timely contractor performance
• changes in commodity and other prices, applicable tariffs, and/or material and equipment availability
• governmental actions
• interconnection uncertainty, delays, and costs for electric generation projects
• operational performance
• changes in environmental, legislative, and regulatory requirements
• regulatory cost recovery
• inflation of labor rates and material and equipment prices
• supply chain disruptions and increased lead times
• barriers to accessing key materials for renewable projects (solar, battery, and other key equipment) created by geopolitical relations

It is possible that adverse events associated with these factors could have a material adverse effect on Consumers.

CMS Energy and Consumers could be affected adversely by legacy litigation and retained liabilities.

The agreements that CMS Energy and Consumers enter into for the sale of assets can include provisions whereby they are required to:

• retain specified preexisting liabilities, such as for taxes, pensions, or environmental conditions
• indemnify the buyers against specified risks, including the inaccuracy of representations and warranties that CMS Energy and Consumers make
• make payments to the buyers depending on the outcome of post-closing adjustments, litigation, audits, or other reviews, including claims resulting from attempts by foreign or domestic governments to assess taxes on past operations or transactions

Many of these contingent liabilities can remain open for extended periods of time after the sales are closed. Depending on the extent to which the buyers might ultimately seek to enforce their rights under these contractual provisions, and the resolution of any disputes concerning them, there could be a material adverse effect on CMS Energy’s or Consumers’ liquidity, financial condition, and results of operations.

Consumers is exposed to risks related to general economic conditions in its service territories.

Consumers’ electric and gas utility businesses are affected by the economic conditions impacting the customers they serve. If the Michigan economy becomes sluggish or declines, Consumers could experience reduced demand for electricity or natural gas that could result in decreased earnings and cash flow. In addition, economic conditions in Consumers’ service territory affect its collections of accounts receivable and levels of lost or stolen gas.

Consumers is exposed to changes in customer usage that could impact financial results.

Technology advances, government incentives and subsidies, and regulatory decisions could increase the cost effectiveness of customer-owned methods of producing electricity and managing energy use resulting in reduced load, cross subsidization, and increased costs.

Customers could also reduce their consumption of electricity and natural gas through energy waste reduction programs. Similarly, customers could also reduce their consumption of natural gas through alternative technologies or fuels or through electrification.

CMS Energy’s and Consumers’ energy sales and operations are affected by seasonal factors and varying weather conditions from year to year.

CMS Energy’s and Consumers’ utility operations are seasonal. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment, while peak demand for natural gas occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel. Accordingly, CMS Energy’s and Consumers’ overall results may fluctuate substantially on a seasonal basis. Mild temperatures during the summer cooling season and winter heating season as well as the impact of extreme weather events on Consumers’ system could have a material adverse effect.

Demand for electricity associated with data center expansion could have a material effect on CMS Energy and Consumers.

Consumers’ utility operations are affected by new customers and load growth. Rapid expansion of data centers associated with increasing demand for cloud services, artificial intelligence, and other applications could lead to an unprecedented increase in demand for electric power in MISO and in Consumers’ service territory. Data center electric demand could require a rapid and significant increase in generation capacity and grid infrastructure in the MISO footprint as well as in Consumers’ service territory, which could have a material effect on CMS Energy and Consumers.

Alternatively, this rapid expansion of data centers and resulting increase in demand for electric power in MISO and in Consumers’ service territory may not develop as anticipated. Efforts to attract data center developers could be unsuccessful as other utilities and regions compete for these projects, which may limit future load growth. In addition, local zoning, permitting, land‑use constraints, and other external factors outside Consumers’ control could impede data center development. If these challenges arise and cannot be effectively mitigated, the anticipated benefits of data center load growth may not materialize. Further, even when data center customers enter into contracts to purchase utility service, there is a risk they may not fulfill their contractual or tariff obligations.

CMS Energy and Consumers are subject to information security risks, risks of unauthorized access to their systems, and technology failures.

In the regular course of business, CMS Energy and Consumers handle a range of sensitive confidential security and customer information. In addition, CMS Energy and Consumers operate in a highly regulated industry that requires the continued operation of sophisticated information and control technology systems and network infrastructure. Despite implementation of security measures, technology systems, including disaster recovery and backup systems, are vulnerable to failure, cyber attacks, unauthorized access, and being disabled. These events could impact the reliability of electric generation and electric and gas delivery and also subject CMS Energy and Consumers to financial harm. Cyber attacks, which include the use of malware, ransomware, computer viruses, and other means for disruption or unauthorized access against companies, including CMS Energy and Consumers, are increasing in frequency, scope, and potential impact. While CMS Energy and Consumers have not been subject to cyber incidents that have had a material impact on their operations to date, their security measures in place may be insufficient to prevent a major cyber incident in the future. If technology systems, including disaster recovery and backup systems, were to fail or be breached, CMS Energy and Consumers might not be able to fulfill critical business functions, and sensitive confidential and proprietary data could be compromised. In addition, because CMS Energy’s and Consumers’ generation, transmission, and distribution systems are part of an interconnected system, a disruption caused by a cyber incident at another utility, electric generator, system operator, or commodity supplier could also adversely affect CMS Energy or Consumers.

A variety of technological tools and systems, including both company-owned IT and technological services provided by outside parties, support critical functions. The failure of these technologies, including backup systems, or the inability of CMS Energy and Consumers to have these technologies supported, updated, expanded, or integrated into other technologies, could hinder their business operations.

CMS Energy’s and Consumers’ businesses have liability risks.

Assets, equipment, and personnel of CMS Energy and Consumers, including electric and gas delivery systems, power plants, gas infrastructure including storage facilities, wind energy or solar equipment, energy products, energy storage assets, vehicle fleets and equipment, other assets, or employees and contractors, could be involved in incidents, failures, or accidents that result in injury, loss of life, or property loss and damage to customers, employees, or the public. Although CMS Energy and Consumers have insurance coverage for many potential incidents (subject to deductibles, limitations, and self‑insurance amounts that could be material), depending upon the nature or severity of any incident, failure, or accident, CMS Energy or Consumers could suffer financial loss, reputational damage, and negative repercussions from regulatory agencies or other public authorities, even where there is no legal liability.

CMS Energy and Consumers are subject to risks that are beyond their control, including but not limited to natural disasters, civil unrest, terrorist attacks and related acts of war, cyber incidents, vandalism, and other catastrophic events.

Natural disasters, severe weather, extreme temperatures, wildfires, fires, smoke, flooding, wars, terrorist acts, civil unrest, vandalism, theft, cyber incidents, government shutdowns, pandemics, and other catastrophic events could result in severe damage to CMS Energy’s and Consumers’ assets beyond what could be recovered through insurance policies (which are subject to deductibles, limitations, and self‑insurance amounts that could be material), could require CMS Energy and Consumers to incur significant upfront costs, and could severely disrupt operations, resulting in loss of service to customers. There is also a risk that regulators could, after the fact, conclude that Consumers’ preparedness or response to such an event was inadequate and take adverse actions as a result.

Energy risk management strategies might not be effective in managing fuel and electricity pricing risks, which could result in unanticipated liabilities to CMS Energy and Consumers or increased volatility in their earnings.

CMS Energy and Consumers are exposed to changes in market prices for commodities including, but not limited to, natural gas, coal, electric capacity, electric energy, emission allowances, gasoline, diesel fuel, and RECs. CMS Energy and Consumers manage commodity price risk using established policies and procedures, and they may use various contracts to manage this risk, including swaps, options, futures, and forward contracts. No assurance can be made that these strategies will be successful in managing CMS Energy’s and Consumers’ risk or that they will not result in net liabilities to CMS Energy or Consumers as a result of future volatility.

A substantial portion of Consumers’ operating expenses for its electric generating plants and vehicle fleet consists of the costs of obtaining commodities. The contracts associated with Consumers’ fuel for electric generation and purchased power are executed in conjunction with the PSCR mechanism, which is designed to allow Consumers to recover prudently incurred costs associated with its positions in these commodities. If the MPSC determined that any of these contracts or related contracting policies were imprudent, recovery of these costs could be disallowed.

Natural gas prices in particular have been historically volatile. Consumers routinely enters into contracts for natural gas to mitigate exposure to the risks of demand, market effects of weather, and changes in commodity prices associated with the gas distribution business. These contracts are executed in conjunction with the GCR mechanism, which is designed to allow Consumers to recover prudently incurred costs associated with its natural gas positions. If the MPSC determined that any of these contracts or related contracting policies were imprudent, recovery of these costs could be disallowed.

CMS Energy and Consumers do not always hedge any or all of the exposure of their operations from commodity price volatility. Furthermore, the ability to hedge exposure to commodity price volatility depends on liquid commodity markets. As a result, to the extent the commodity markets are illiquid, CMS Energy and Consumers might not be able to execute their risk management strategies, which could result in larger unhedged positions than preferred at a given time. To the extent that unhedged positions exist, fluctuating commodity prices could have a negative effect on CMS Energy and Consumers. Changes in laws that limit CMS Energy’s and Consumers’ ability to hedge could also have a negative effect on CMS Energy and Consumers.

CMS Energy and Consumers might not be able to obtain an adequate supply of natural gas or coal, which could limit their ability to operate electric generation facilities or serve Consumers’ natural gas customers.

CMS Energy and Consumers have contracts in place for the supply and transportation of the natural gas, coal, and other fuel sources they require for their electric generating capacity. Consumers also has interstate transportation and supply agreements in place to facilitate delivery of natural gas to its customers. Apart from the contractual and monetary remedies available to CMS Energy and Consumers in the event of a counterparty’s failure to perform under any of these contracts, there can be no assurances that the counterparties to these contracts will fulfill their obligations to provide natural gas or coal to CMS Energy or Consumers. The counterparties under the agreements could experience financial or operational problems that inhibit their ability to fulfill their obligations to CMS Energy or Consumers. In addition, counterparties under these contracts might not be required to supply natural gas or coal to CMS Energy or Consumers under certain circumstances, such as in the event of a natural disaster or severe weather.

If Consumers were unable to obtain its supply requirements, it could be required to purchase natural gas or coal at higher prices, implement its natural gas curtailment program filed with the MPSC, or purchase replacement power at higher prices.

Unplanned outages or maintenance could be costly for CMS Energy or Consumers.

Unforeseen outages or maintenance of the electric and gas delivery systems, power plants, gas infrastructure including storage facilities and compression stations, wind energy or solar equipment, energy storage assets, and energy products owned in whole or in part by CMS Energy or Consumers may be required for many reasons. When unplanned outages occur, CMS Energy and Consumers will not only incur unexpected maintenance expenses, but may also have to make spot market purchases of electric and gas commodities that may exceed CMS Energy’s or Consumers’ expected cost of generation or gas supply, be forced to curtail services, or retire a given asset if the cost or timing of the maintenance is not reasonable and prudent. Unplanned generator outages could reduce the capacity credit CMS Energy or Consumers receives from MISO and could cause CMS Energy or Consumers to incur additional capacity costs in future years.

General Risk Factors

CMS Energy and Consumers are exposed to counterparty risk.

Adverse economic conditions or financial difficulties experienced by counterparties with whom CMS Energy and Consumers do business could impair the ability of these counterparties to pay for CMS Energy’s and Consumers’ services and/or fulfill their contractual obligations, including performance and payment of damages. CMS Energy and Consumers depend on these counterparties to remit payments and perform contracted services in a timely and adequate fashion. In addition, any delay or default in payment or performance, including inadequate performance, of contractual obligations (such as contractual obligations by third parties to purchase utility services, perform work, supply equipment, provide services, and meet related specifications or requirements), could have a material adverse effect on CMS Energy and Consumers.

Volatility and disruptions in capital and credit markets could have a negative impact on CMS Energy’s and Consumers’ lenders, vendors, contractors, suppliers, customers, and other counterparties, causing them to fail to meet their obligations.

CMS Energy and Consumers are exposed to significant reputational risks.

CMS Energy and Consumers could suffer negative impacts to their reputations as a result of operational incidents, accidents, actual or perceived violations of corporate policies or regulatory violations, inappropriate use of social media, or other events. Reputational damage could have a material adverse effect and could result in negative customer perception and increased regulatory oversight.

A work interruption or other union actions could adversely affect CMS Energy and Consumers.

At December 31, 2025, unions represent 45 percent of Consumers’ employees and 22 percent of NorthStar Clean Energy’s employees. Consumers’ union agreements expire in 2030 and the majority of NorthStar Clean Energy’s represented employees have an agreement that expires in 2029. If these employees were to engage in a strike, work stoppage, or other slowdown, CMS Energy or Consumers could experience a significant disruption in its operations and higher ongoing labor costs.

Failure to attract and retain an appropriately qualified workforce could adversely impact CMS Energy’s and Consumers’ results of operations.

In some areas, competition for skilled employees is high and if CMS Energy and Consumers were unable to match skill sets to future needs, they could encounter operating challenges and increased costs. These challenges could include a lack of resources, loss of knowledge, and delays in skill development. Additionally, higher costs could result from the use of contractors to replace employees, loss of productivity, and safety incidents. Failing to train replacement employees adequately and to transfer internal knowledge and expertise could adversely affect CMS Energy’s and Consumers’ ability to manage and operate their businesses.

Enterprise Risk Management: CMS Energy and Consumers manage security risks, including cybersecurity risks, through a robust enterprise risk management program that includes people, processes, technology, and governance structures. The enterprise risk management program identifies risks that may significantly impact the business and informs the companies’ risk-mitigation strategies. The enterprise risk management program is reviewed with the Board at least annually.

Cybersecurity Program: CMS Energy’s and Consumers’ security function, led by the Vice President of IT and Security and CIO, is accountable for cyber and physical security and is subject to various state, federal, and industry cybersecurity, physical security, and privacy regulations. Their cybersecurity program is responsible for assessing, identifying, and managing risks from cybersecurity threats using industry frameworks, as well as best practices developed by government and industry partners. All employees and contractors are required to complete annual trainings on a variety of security-related topics. Additionally, the companies continuously upgrade technological investments designed to prevent, detect, and respond to attacks. The companies’ electric, natural gas, and corporate systems each follow standards, controls, and requirements designed to maintain compliance with applicable regulations and standards, such as MPSC, NERC critical infrastructure protection, and payment card industry regulations. Technology projects and third-party service providers are reviewed for adherence to cybersecurity requirements.

CMS Energy’s and Consumers’ cybersecurity program focuses on finding and remediating vulnerabilities in their systems. The companies use third-party firms for penetration testing, audits, and assessments, and conduct technical exercises to practice their response to simulated events as well as tabletop exercises to test that response using their incident command system, including leadership decisions. The companies also have a dedicated, proactive function focused fully on monitoring CMS Energy’s and Consumers’ systems and responding when cybersecurity attacks occur. This includes regular information sharing with industry partners, peer utilities, and state and federal partners. The companies’ incident response plan outlines the individuals responsible, the methods employed, and the timeline for notifying state and federal governmental agencies. The companies retain a third-party cybersecurity firm to assist with potentially significant cybersecurity incidents and have invested in cybersecurity insurance to offset costs incurred from any such cybersecurity incidents. To manage cybersecurity risks associated with the companies’ use of third-party service providers, the companies incorporate security requirements into contracts, when deemed applicable, and pursue third-party security certifications for vendors with a higher risk profile.

CMS Energy and Consumers have experienced no material cybersecurity incidents; however, future cybersecurity incidents could materially affect their business strategy, results of operations, or financial condition. For additional details regarding these and other uncertainties, see Item 1A. Risk Factors.

Management’s Role: The Vice President of IT and Security and CIO has over 25 years of IT and security experience and, to enhance governance, reports to the Executive Vice President of Business Transformation and Chief Legal and Administrative Officer. The Vice President of IT and Security and CIO is responsible for informing the CEO and other members of senior management, as necessary, about cybersecurity incidents, covering prevention, detection, mitigation, and remediation efforts as they are detected by the cybersecurity team. Cybersecurity incidents are managed using the companies’ standard process for critical events. In the event of such cybersecurity incidents, the Vice President of IT and Security and CIO communicates and collaborates with the officers of the companies and subject matter experts to address business continuity, contingency, and recovery plans. Senior management will notify the Board, including the Audit Committee, of any significant cybersecurity incidents.

Board Oversight: As part of the Board’s risk oversight process, 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. Of note, two members of the Board have extensive industry experience in cybersecurity and are on CMS Energy’s and Consumers’ Audit Committee.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations is a combined report of CMS Energy and Consumers.

Executive Overview

CMS Energy is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including Consumers, an electric and gas utility, and NorthStar Clean Energy, primarily a domestic independent power producer and marketer. Consumers’ electric utility operations include the generation, purchase, distribution, and sale of electricity, and Consumers’ gas utility operations include the purchase, transmission, storage, distribution, and sale of natural gas. Consumers’ customer base consists of a mix of primarily residential, commercial, and diversified industrial customers. NorthStar Clean Energy, through its subsidiaries and equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production.

CMS Energy and Consumers manage their businesses by the nature of services each provides. CMS Energy operates principally in three business segments: electric utility; gas utility; and NorthStar Clean Energy, its non‑utility operations and investments. Consumers operates principally in two business segments: electric utility and gas utility. CMS Energy’s and Consumers’ businesses are affected primarily by:

• regulation and regulatory matters
• state and federal legislation
• economic conditions
• load growth
• weather
• energy commodity prices
• interest rates
• their securities’ credit ratings

The Triple Bottom Line

CMS Energy’s and Consumers’ purpose is to provide safe, reliable, affordable, clean, and equitable energy in service of their customers. In support of this purpose, CMS Energy and Consumers couple digital transformation with the “CE Way,” a lean operating system designed to improve safety, quality, cost, delivery, and employee morale.

CMS Energy and Consumers measure their progress toward the purpose by considering their impact on the “triple bottom line” of people, planet, and prosperity; this consideration takes into account not only the economic value that CMS Energy and Consumers create for customers and investors, but also their 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 CMS Energy’s and Consumers’ activities.

CMS Energy’s Sustainability Report, which is available to the public, describes CMS Energy’s and Consumers’ progress toward world class performance measured in the areas of people, planet, and prosperity.

People: The people element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to their employees, their customers, the residents of local communities in which they do business, and other stakeholders.

The safety of co-workers, customers, and the general public is a priority of CMS Energy and Consumers. Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture. These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions.

CMS Energy and Consumers also place a high priority on customer value and on providing reliable, affordable, and equitable energy in service of their customers. Consumers’ customer-driven investment program is aimed at improving safety and increasing electric and gas reliability.

In the electric rate case it filed with the MPSC in June 2025, Consumers updated its Reliability Roadmap, a five‑year strategy to improve Consumers’ electric distribution system and the reliability of the grid. The plan proposes spending through 2029 for projects designed to reduce the number and duration of power outages to customers through investment in infrastructure upgrades, vegetation management, and grid modernization. Consumers has requested rate recovery of the investments needed to achieve the Reliability Roadmap’s key objectives in its electric rate cases.

Central to Consumers’ commitment to its customers are the initiatives it has undertaken to keep electricity and natural gas affordable, including:

• replacement of coal-fueled generation and PPAs with a cost-efficient and reliable mix of renewable energy, less-costly dispatchable generation sources, and energy waste reduction and demand response programs
• targeted infrastructure investment to reduce maintenance costs and improve reliability and safety
• supply chain optimization
• economic development to increase sales and reduce overall rates
• information and control system efficiencies
• employee and retiree health care cost sharing
• tax planning
• cost-effective financing
• workforce productivity enhancements

While inflationary pressures and tariffs could impact supply chain availability and pricing, CMS Energy and Consumers are taking steps to help mitigate the impact on their ability to provide safe, reliable, affordable, clean, and equitable energy in service of their customers.

Planet: The planet element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to protect the environment. This commitment extends beyond compliance with various state and federal environmental, health, and safety laws and regulations. Management considers climate change and other environmental risks in strategy development, business planning, and enterprise risk management processes.

CMS Energy and Consumers continue to focus on opportunities to protect the environment and reduce their carbon footprint from owned generation. CMS Energy, including Consumers, has decreased its combined percentage of electric supply (self-generated and purchased) from coal by 24 percentage points since 2015. Additionally, as a result of actions already taken through 2025, preliminary data indicates Consumers has:

• reduced carbon dioxide emissions from owned generation by nearly 30 percent since 2005
• reduced methane emissions by more than 40 percent since 2012
• reduced the volume of water used to generate electricity by nearly 60 percent since 2012
• reduced landfill waste disposal by more than 2 million tons since 1992
• enhanced, restored, or protected more than 13,500 acres of land since 2017
• reduced sulfur dioxide and particulate matter emissions by more than 90 percent since 2005
• reduced NOx emissions by more than 85 percent since 2005
• reduced mercury emissions by more than 90 percent since 2007

Presented in the following illustration are Consumers’ reductions in these emissions:

In 2023, Michigan enacted the 2023 Energy Law, which among other things:

• increased the renewable energy standard from 15 percent to 50 percent by 2030 and 60 percent by 2035; renewable energy generated anywhere within MISO can be applied to meeting this standard, with certain limitations
• established a clean energy standard of 80 percent by 2035 and 100 percent by 2040; low- or zero‑carbon emitting resources, such as nuclear generation and natural gas generation coupled with carbon capture, qualify as clean energy sources under this standard
• enhanced existing incentives for energy efficiency programs and returns earned on new clean or renewable PPAs
• created a new energy storage standard, requiring electric utilities to file plans by 2029 to help achieve a statewide target of 2,500 MW
• expanded the statutory cap on distributed generation resources to 10 percent of the electric utility’s five‑year average peak load

Consumers’ Electric Supply Plan, its long-term strategy for delivering safe, reliable, affordable, clean, and equitable energy to its customers, is outlined in its integrated resource plan and incorporates Consumers’ Renewable Energy Plan. The Electric Supply Plan is Consumers’ blueprint for compliance with Michigan’s 2023 Energy Law and for advancing sustainability objectives.

To meet these objectives, Consumers is executing a multi-faceted strategy. This strategy involves taking steps to end the use of coal, including the retirement of the D.E. Karn coal-fueled generating units, totaling 515 MW of nameplate capacity, in 2023 and obtaining MPSC approval to retire J.H. Campbell, totaling 1,407 MW of nameplate capacity. The retirement of J.H. Campbell is subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy. For a more detailed discussion of the emergency orders, see Consumers Electric Utility Outlook and Uncertainties—J.H. Campbell Emergency Orders and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

To continue providing controllable sources of electricity to customers, Consumers purchased the Covert Generating Station, representing 1,200 MW of nameplate capacity, in 2023 and has solicited additional capacity from controllable sources of electricity to customers.

Consumers’ updates to its Renewable Energy Plan include up to 9,000 MW of both purchased and owned solar energy resources and up to 4,000 MW of wind energy resources. Coupled with updates to its integrated resource plan, these actions position Consumers to achieve 60‑percent renewable energy by 2035 and 100‑percent clean energy by 2040, and will also contribute to Consumers’ achievement of the emissions reductions goals discussed below.

Under its Methane Reduction Plan, Consumers has set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent from 2012 baseline levels by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will likely be offset through clean fuel alternatives or nature-based carbon removal pathways. To date, Consumers has reduced methane emissions by more than 40 percent.

Consumers has also set a goal to reduce customer greenhouse gas emissions by 25 percent by 2035. Consumers expects to meet this goal through carbon offset measures, renewable natural gas, energy efficiency and demand response programs, and the adoption of cost-effective emerging technologies once proven and commercially available.

Additionally, to advance its environmental stewardship in Michigan and to minimize the impact of future regulations, Consumers set the following goals for the five‑year period 2023 through 2027:

• to enhance, restore, or protect 6,500 acres of land through 2027; Consumers surpassed this goal during the three‑year period 2023 through 2025 and enhanced, restored, or protected 6,700 acres of land
• to reduce water usage by 1.7 billion gallons through 2027; Consumers had reduced water usage by more than 1.9 billion gallons towards this goal
• to annually divert a minimum of 90 percent of waste from landfills (through waste reduction, recycling, and reuse); during 2025, Consumers’ rate of waste diverted from landfills was 93 percent

CMS Energy and Consumers are monitoring numerous legislative, policy, executive, and regulatory initiatives, including those related to regulation and reporting of greenhouse gases, and related litigation. While CMS Energy and Consumers cannot predict the outcome of these matters, which could affect them materially, they intend to continue to move forward with a triple-bottom-line approach that focuses on people, planet, and prosperity.

Prosperity: The prosperity element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to meeting their financial objectives and providing economic development opportunities and benefits in the communities in which they do business. CMS Energy’s and Consumers’ financial strength allows them to maintain solid investment-grade credit ratings and thereby reduce funding costs for the benefit of customers and investors, to attract and retain talent, and to reinvest in the communities they serve.

In 2025, CMS Energy’s net income available to common stockholders was $1.1 billion, and diluted EPS were $3.53. This compares with net income available to common stockholders of $993 million and diluted EPS of $3.33 in 2024. In 2025, higher gas and electric sales, due primarily to favorable weather, and electric and gas rate increases were offset partially by increased depreciation and property taxes, reflecting higher capital spending, and higher interest charges. A more detailed discussion of the factors affecting CMS Energy’s and Consumers’ performance can be found in the Results of Operations section that follows this Executive Overview.

Over the next five years, Consumers expects weather-normalized electric deliveries to increase compared to 2025. This outlook reflects strong growth in electric demand, offset partially by the effects of energy waste reduction programs. Weather-normalized gas deliveries are expected to remain stable relative to 2025, reflecting modest growth in gas demand, offset by the effects of energy waste reduction programs.

Performance: Impacting the Triple Bottom Line

CMS Energy and Consumers remain committed to delivering safe, reliable, affordable, clean, and equitable energy in service of their customers and positively impacting the triple bottom line of people, planet, and prosperity. During 2025, CMS Energy and Consumers:

• connected over 140,000 customers with $60 million in energy-bill assistance and helped make over $100 million in statewide aid available for 2026, reinforcing Consumers’ commitment to affordability
• began operations at Muskegon Solar Energy Center, a 1,900‑acre project generating 250 MW of clean energy to power 40,000 homes and businesses, supporting Michigan’s energy needs and advancing the company’s long‑term clean energy strategy
• reached an agreement with a new data center expected to add more than 1 GW of incremental load growth in our service territory, supporting long-term sales growth and delivering economic benefits for Michigan
• expanded the use of drone technology enabling faster, safer inspections of 400 miles of hard-to-reach power lines and infrastructure resulting in reduced average outage time per customer and improved storm recovery capabilities
• announced the launch of “Green Giving,” a program enabling the general public to contribute to renewable energy while offering financial benefits to low-income customers, along with a new Residential Renewable Energy Program, which allows customers of all income levels to subscribe and match their energy usage with renewable energy sources, supporting clean energy initiatives
• moved forward with an aggressive plan to enhance grid reliability for nearly 2 million homes and businesses by clearing trees along 8,000 miles of power lines and creating a modern, stronger, and more resilient power grid through infrastructure upgrades and technology investments
• deployed eight state-of-the-art vehicles that survey the company’s nearly 30,000‑mile gas distribution system to find methane emissions, enhancing safety and reliability for Consumers’ natural gas customers
• experienced success with the underground power line pilot program in early 2025, with pilot areas seeing 100‑percent reduction in storm-related outages and improved customer satisfaction

CMS Energy and Consumers will continue to utilize the CE Way to enable them to achieve world class performance and positively impact the triple bottom line. Consumers’ investment plan and the regulatory environment in which it operates also drive its ability to impact the triple bottom line.

Investment Plan: Over the next five years, Consumers expects to make significant expenditures on infrastructure upgrades, replacements, and clean generation. While it has a large number of potential investment opportunities that would add customer value, Consumers has prioritized its spending based on the criteria of enhancing public safety, increasing reliability, maintaining affordability for its customers, and advancing its environmental stewardship. Consumers’ investment program, which is subject to approval through general rate case and other MPSC proceedings, is expected to result in annual rate-base growth of more than 8 percent. This rate-base growth, together with cost-control measures, should allow Consumers to maintain affordable customer prices.

Presented in the following illustration are Consumers’ planned capital expenditures through 2030 of $24.1 billion:

Of this amount, Consumers plans to spend $8.8 billion on electric generation, which includes solar, wind, and natural gas-fueled generation, as well as energy storage. Consumers also expects to spend $15.3 billion over the next five years primarily to maintain and upgrade its electric distribution systems and gas infrastructure in order to enhance safety and reliability, improve customer satisfaction, reduce energy waste on those systems, and facilitate its clean energy transformation. Electric distribution and other projects comprise $8.6 billion primarily to strengthen circuits and substations, replace poles, and interconnect clean energy resources. The gas infrastructure projects comprise $6.7 billion to sustain deliverability, enhance pipeline integrity and safety, and reduce methane emissions.

Regulation: Regulatory matters are a key aspect of Consumers’ business, particularly rate cases and regulatory proceedings before the MPSC, which permit recovery of new investments while helping to ensure that customer rates are fair and affordable. Important regulatory events and developments not already discussed are summarized below.

2024 Electric Rate Case: In March 2025, the MPSC issued an order authorizing an annual rate increase of $176 million, which is inclusive of a $22 million surcharge for the recovery of distribution investments made in 2023 that exceeded the rate amounts authorized in accordance with previous electric rate orders. The approved rate increase is based on a 9.90‑percent authorized return on equity. The new rates became effective in April 2025

2025 Electric Rate Case: In June 2025, Consumers filed an application with the MPSC seeking a rate increase of $460 million, made up of two components. First, Consumers requested a $436 million annual rate increase, based on a 10.25‑percent authorized return on equity for the projected 12‑month period ending April 30, 2027. The filing requested authority to recover costs related to new infrastructure investment primarily in distribution system reliability. Second, Consumers requested approval of a $24 million surcharge for the recovery of distribution investments made during the 12 months ended February 28, 2025 that exceeded the rate amounts authorized in accordance with previous electric rate orders. In October 2025, Consumers revised its requested increase to $447 million, which includes the $24 million surcharge to recover deferred distribution investments. The MPSC must issue a final order in this case before or in April 2026.

2024 Gas Rate Case: In September 2025, the MPSC issued an order authorizing an annual rate increase of $157.5 million, based on a 9.80‑percent authorized return on equity. The new rates became effective in November 2025.

2025 Gas Rate Case: In December 2025, Consumers filed an application with the MPSC seeking an annual rate increase of $240 million based on a 10.25‑percent authorized return on equity for the projected 12‑month period ending October 31, 2027. The MPSC must issue a final order in this case before or in October 2026.

Looking Forward

CMS Energy and Consumers will continue to consider the impact on the triple bottom line of people, planet, and prosperity in their daily operations as well as in their long-term strategic decisions. Consumers will continue to seek fair and timely regulatory treatment that will support its customer-driven investment plan, while pursuing cost-control measures that will allow it to maintain sustainable customer base rates. The CE Way is an important means of realizing CMS Energy’s and Consumers’ purpose of providing safe, reliable, affordable, clean, and equitable energy in service of their customers.

Capital Resources and Liquidity

CMS Energy and Consumers expect to have sufficient liquidity to fund their present and future commitments. CMS Energy uses dividends and tax-sharing payments from its subsidiaries and external financing and capital transactions to invest in its utility and non‑utility businesses, retire debt, pay dividends, and fund its other obligations. The ability of CMS Energy’s subsidiaries, including Consumers, to pay dividends to CMS Energy depends upon each subsidiary’s revenues, earnings, cash needs, and other factors. In addition, Consumers’ ability to pay dividends is restricted by certain terms included in its articles of incorporation and potentially by FERC requirements and provisions under the Federal Power Act and the Natural Gas Act. For additional details on Consumers’ dividend restrictions, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 5, Financings and Capitalization—Dividend Restrictions. During the year ended December 31, 2025, Consumers paid $898 million in dividends on its common stock to CMS Energy.

Consumers uses cash flows generated from operations, external financing transactions, and the monetization of tax credits, along with stockholder contributions from CMS Energy, to fund capital expenditures, retire debt, pay dividends, and fund its other obligations. Consumers also uses these sources of funding to contribute to its employee benefit plans.

Financing and Capital Resources: CMS Energy and Consumers rely on the capital markets to fund their robust capital plan. Barring any sustained market dislocations or disruptions, CMS Energy and Consumers expect to continue to have ready access to the financial and capital markets and will continue to explore possibilities to take advantage of market opportunities as they arise with respect to future funding needs. If access to these markets were to diminish or otherwise become restricted, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending.

In 2023, CMS Energy entered into an equity offering program under which it may sell shares of its common stock having an aggregate sales price of up to $1 billion in privately negotiated transactions, in “at the market” offerings, or through forward sales transactions. During the year ended December 31, 2025, CMS Energy settled forward sale contracts issued under this program, resulting in net proceeds of $497 million. Following these settlements, CMS Energy has $8 million in outstanding forward contracts under the program, maturing November 30, 2026.

CMS Energy, NorthStar Clean Energy, and Consumers use revolving credit facilities for general working capital purposes and to issue letters of credit. At December 31, 2025, CMS Energy had $715 million of its revolving credit facility available, NorthStar Clean Energy had $5 million available under its revolving credit facility, and Consumers had $1.4 billion available under its revolving credit facilities.

An additional source of liquidity is Consumers’ commercial paper program, which allows Consumers to issue, in one or more placements, up to $500 million in aggregate principal amount of commercial paper notes with maturities of up to 365 days at market interest rates. These issuances are supported by Consumers’ revolving credit facilities. While the amount of outstanding commercial paper does not reduce the available capacity of the revolving credit facilities, Consumers does not intend to issue commercial paper in an amount exceeding the available capacity of the facilities. At December 31, 2025, there were no commercial paper notes outstanding under this program.

For additional details about these programs and facilities, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 5, Financings and Capitalization.

Certain of CMS Energy’s, NorthStar Clean Energy’s, and Consumers’ credit agreements contain covenants that require each entity to maintain certain financial ratios, as defined therein. At December 31, 2025, no default had occurred with respect to any of the financial covenants contained in these credit agreements. Each of the entities was in compliance with the covenants contained in their respective credit agreements as of December 31, 2025, as presented in the following table:

1Applies to CMS Energy’s revolving credit agreement and letter of credit reimbursement agreement.

2Applies to NorthStar Clean Energy’s revolving credit agreement.

3The aggregate book value of the pledged equity interests under the revolving credit agreement was at least two‑times the aggregate commitment under the revolving credit agreement at December 31, 2025.

4Applies to Consumers’ revolving credit agreements and certain letter of credit reimbursement agreements.

Material Cash Requirements: Based on the present investment plan, during 2026, CMS Energy, including Consumers, projects capital expenditures of $4.4 billion and Consumers projects capital expenditures of $4.1 billion. CMS Energy’s 2026 contractual commitments comprise $2.4 billion of purchase obligations and $1.8 billion of principal and interest payments on long-term debt. Consumers’ 2026 contractual commitments comprise $2.1 billion of purchase obligations and $1.1 billion of principal and interest payments on long-term debt.

Components of CMS Energy’s and Consumers’ cash management plan include controlling operating expenses and capital expenditures and evaluating market conditions for financing and refinancing opportunities. CMS Energy’s and Consumers’ present level of cash and expected cash flows from operating activities, together with access to sources of liquidity, are anticipated to be sufficient to fund contractual obligations and other material cash requirements for 2026 and beyond.

Capital Expenditures: Over the next five years, CMS Energy and Consumers expect to make substantial capital investments. The companies may revise their forecast of capital expenditures periodically due to a number of factors, including environmental regulations, MPSC approval or disapproval, business opportunities, market volatility, economic trends, and the ability to access capital. Presented in the following table are CMS Energy’s and Consumers’ estimated capital expenditures, including lease commitments, for 2026 through 2030:

In Billions

Other Material Cash Requirements: Presented in the following table are CMS Energy’s and Consumers’ material cash obligations from known contractual and other legal obligations:

Purchase obligations arise from long-term contracts for the purchase of commodities and related services, primarily long-term PPAs, and construction and service agreements. For more information on CMS Energy’s and Consumers’ purchase obligations, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments—Contractual Commitments.

CMS Energy, Consumers, and certain of their subsidiaries enter into various arrangements in the normal course of business to facilitate commercial transactions with third parties. These arrangements include indemnities, surety bonds, letters of credit, and financial and performance guarantees. For additional details on indemnity and guarantee arrangements, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments—Guarantees. For additional details on letters of credit and CMS Energy’s forward sales contracts, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 5, Financings and Capitalization.

Outlook

Several business trends and uncertainties may affect CMS Energy’s and Consumers’ financial condition and results of operations. These trends and uncertainties could have a material impact on CMS Energy’s and Consumers’ consolidated income, cash flows, or financial position.

During 2025, the federal government took numerous executive actions related to tariffs and trade, alleviating regulatory burdens, and environmental regulations and enforcement, among other areas of potential impact. Many of these actions require further implementation by federal agencies and departments, and some of these actions will likely be subject to further judicial review. CMS Energy and Consumers continue to monitor these executive actions and will continue taking steps to deliver consistently on the triple bottom line.

For additional details regarding these and other uncertainties, see Forward-looking Statements and Information; Item 1A. Risk Factors; and Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters and Note 4, Contingencies and Commitments.

Consumers Electric Utility Outlook and Uncertainties

Energy Supply: Consumers’ Electric Supply Plan, its long-term strategy for delivering safe, reliable, affordable, clean, and equitable energy to its customers, is outlined in its integrated resource plan and incorporates Consumers’ Renewable Energy Plan. The Electric Supply Plan is Consumers’ blueprint for compliance with Michigan’s 2023 Energy Law and for advancing sustainability objectives.

Among other things, the 2023 Energy Law:

• increased the renewable energy standard from 15 percent to 50 percent by 2030 and 60 percent by 2035
• established a clean energy standard of 80 percent by 2035 and 100 percent by 2040; low- or zero‑carbon emitting resources, such as nuclear generation and natural gas generation coupled with carbon capture, qualify as clean energy sources under this standard
• created a new energy storage standard, requiring electric utilities to file plans by 2029 to help achieve a statewide target of 2,500 MW; the MPSC Staff has indicated that Consumers’ share of this target is 817 MW

Consumers’ integrated resource planning process provides a clear path toward these goals. Updates to its integrated resource plan will be filed in 2026 to reinforce and expand that pathway, while recent updates to the Renewable Energy Plan—approved by the MPSC in September 2025—position Consumers to achieve 60‑percent renewable energy by 2035 and 100‑percent clean energy by 2040.

To meet these objectives, Consumers is executing a multi-faceted strategy:

• Ending the use of coal—In 2023, Consumers retired the D.E. Karn coal-fueled generating units, totaling 515 MW of nameplate capacity, and as authorized by the MPSC, issued securitization bonds to finance the recovery of and return on those units. Additionally, Consumers obtained MPSC approval to retire J.H. Campbell in May 2025, totaling 1,407 MW of nameplate capacity, and to recover its remaining book value plus a 9.0‑percent return on equity through regulatory asset treatment upon its retirement. As discussed further below, the retirement of J.H. Campbell is subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy.
• Resource adequacy and reliability—To maintain reliability during the transition, Consumers purchased the Covert Generating Station, representing 1,200 MW of nameplate capacity, in 2023. Additionally, in September 2025, Consumers entered into a new 10‑year PPA with the MCV Partnership for the purchase of up to 1,240 MW of capacity and associated energy from the MCV Facility, effective June 1, 2030.
• Energy storage investments—Consumers has contracted to purchase 850 MW of capacity from battery storage facilities to be located in Michigan’s Lower Peninsula and with expected commercial operation dates through 2028.
• Renewable expansion—Recent Renewable Energy Plan updates include up to 4,000 MW of wind energy resources and up to 9,000 MW of both purchased and owned solar energy resources, of which 1,060 MW will support Consumers’ voluntary green pricing program.

Presented in the following illustration is the aggregate renewable capacity that Consumers expects to add to its portfolio through PPAs and owned generation under its integrated resource plan, voluntary green pricing program, and Renewable Energy Plan updates:

The company earns a return equal to its pre-tax weighted-average cost of capital on permanent capital structure for payments under new clean, renewable, or energy storage PPAs with non-affiliated entities.

Consumers will continue to competitively bid new capacity and energy resources, ensuring a balanced portfolio of intermittent renewables and dispatchable clean resources. Any resulting contracts are subject to MPSC approval. Through these integrated plans, Consumers is advancing Michigan’s clean energy transition while maintaining system reliability, affordability, and regulatory compliance.

J.H. Campbell Emergency Orders: In May 2025, before the planned closure of J.H. Campbell, the U.S. Secretary of Energy issued an emergency order under section 202(c) of the Federal Power Act requiring J.H. Campbell to continue operating for 90 days, through August 20, 2025. Subsequently, the

U.S. Secretary of Energy issued two additional emergency orders for 90 days each, ultimately requiring continued operation of J.H. Campbell through February 17, 2026. These orders stated that continued operation of J.H. Campbell was required to meet an energy emergency across MISO’s North and Central regions. Consistent with the Federal Power Act and DOE regulations, the orders authorize Consumers to obtain cost recovery at FERC.

As directed, Consumers has continued to make J.H. Campbell available in the MISO market and, in June 2025, filed a complaint at FERC seeking a modification of the MISO Tariff to establish a mechanism for recovery and allocation of the cost to comply with this order. In August 2025, FERC granted Consumers’ complaint and ordered MISO to revise its tariff accordingly. MISO submitted a compliance filing with FERC in September 2025, and FERC approval of the compliance filing remains pending. For additional discussion of this FERC proceeding and Consumers’ request for recovery, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

Following the May 2025 emergency order, several third-party stakeholders, including the Michigan Attorney General, the Organization of MISO States, and a group of environmental and public interest groups, asked the U.S. Secretary of Energy to reconsider the May 2025 emergency order. In July 2025, after the U.S. Secretary of Energy took no action on those requests, several parties filed petitions for review of the May 2025 emergency order in federal court. The requests for rehearing were subsequently denied, and similar challenges to the August and November 2025 orders are underway. The U.S. Secretary of Energy may issue more orders to require the continued operation of J.H. Campbell. While the timing and content of future orders and the outcome of third-party legal challenges are not yet known, Consumers is committed to pursuing cost recovery as provided for under applicable laws, orders, and proceedings.

Electric Customer Deliveries and Revenue: Consumers’ electric customer deliveries are seasonal and largely dependent on Michigan’s economy. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment. In addition, Consumers’ electric rates, which follow a seasonal rate design, are higher in the summer months than in the remaining months of the year. Each year in June, electric residential customers transition to a summer peak time-of-use rate that allows them to take advantage of lower-cost energy during off-peak times during the summer months. Thus, customers can reduce their electric bills by shifting their consumption from on‑peak to off‑peak times.

Over the next five years, Consumers expects weather-normalized electric deliveries to increase compared to 2025. This outlook reflects strong growth in electric demand, offset partially by the effects of energy waste reduction programs. Actual delivery levels will depend on:

• energy conservation measures and results of energy waste reduction programs
• weather fluctuations
• Michigan’s economic conditions, including data center expansion; utilization, expansion, or contraction of large commercial and industrial facilities; economic development; population trends; electric vehicle adoption; and housing activity

Electric ROA: Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at 10 percent of Consumers’ sales, with certain exceptions. At December 31, 2025, electric deliveries under the ROA program were at the 10‑percent limit. Fewer than 300 of Consumers’ electric customers purchased electric generation service under the ROA program.

In 2016, Michigan law established a path to ensure that forward capacity is secured for all electric customers in Michigan, including customers served by alternative electric suppliers under ROA. The law also authorized the MPSC to ensure that alternative electric suppliers have procured enough capacity to cover their anticipated capacity requirements for the four‑year forward period. In 2017, the MPSC issued an order establishing a state reliability mechanism for Consumers. Under this mechanism, if an alternative electric supplier does not demonstrate that it has procured its capacity requirements for the four‑year forward period, its customers will pay a set charge to the utility for capacity that is not provided by the alternative electric supplier.

During 2017, the MPSC issued orders finding that it has statutory authority to determine and implement a local clearing requirement, which requires all electric suppliers to demonstrate that a portion of the capacity used to serve customers is located in the MISO footprint in Michigan’s Lower Peninsula. In 2020, the Michigan Supreme Court affirmed the MPSC’s statutory authority to implement a local clearing requirement on individual electric providers.

In 2020, ABATE and another intervenor filed a complaint against the MPSC in the U.S. District Court for the Eastern District of Michigan challenging the constitutionality of a local clearing requirement. The complaint requested the federal court to issue a permanent injunction prohibiting the MPSC from implementing a local clearing requirement on individual electric providers. In 2023, the U.S. District Court for the Eastern District of Michigan dismissed the complaint. ABATE and the other intervenor filed a claim of appeal of the Eastern District Court’s decision with the U.S. Court of Appeals for the Sixth Circuit.

In January 2025, the Sixth Circuit Court of Appeals issued an opinion finding that the MPSC’s imposition of a local clearing requirement on individual electric suppliers would discriminate against interstate commerce. The Court of Appeals remanded to the District Court for a determination of whether the local clearing requirement discriminated against interstate commerce and whether the MPSC’s regulation survives a strict scrutiny standard, which depends on a determination of whether the local clearing requirement is the only means of achieving the state’s goal of securing reliable energy supply. In January 2025, Consumers filed a petition for rehearing and en banc review with the Sixth Circuit Court of Appeals, requesting the Court to reconsider and reverse the panel’s opinion. In February 2025, the Sixth Circuit Court of Appeals issued an order denying Consumers’ petition for rehearing and en banc review. The case has therefore been remanded to the District Court for the Eastern District of Michigan for consideration of whether the MPSC’s local clearing requirement meets the strict scrutiny standard pursuant to the Court of Appeals’ decision. The remanded proceeding has begun at the Eastern District Court; there is no deadline for decision.

Sale of Hydroelectric Facilities: In September 2025, Consumers signed an agreement to sell its 13 river hydroelectric dams, which are located throughout Michigan, to a non-affiliated company. Additionally, Consumers signed an agreement to purchase power generated by the facilities for 30 years, at a price that reflects the counterparty’s acceptance of the risks and rewards of ownership of the facilities, including FERC licensing obligations. The agreements are contingent upon MPSC and FERC approval, for which Consumers filed in October 2025. Timing of the regulatory review process is uncertain and could extend 12 to 18 months or longer. In Consumers’ most recent electric rate case, the MPSC approved deferred accounting treatment for costs of owning and operating the hydroelectric dams pending and until completion of the transaction. At December 31, 2025, the net book value of the hydroelectric facilities was immaterial.

To ensure necessary staffing at the hydroelectric facilities through the anticipated sale, Consumers has provided current employees at the facilities with a retention incentive program. Subsequently, to ensure continued safe operation of the facilities after the sale, the buyer will offer employment to the current hydroelectric employees for a period of at least a year. The retention incentive benefits are contingent upon MPSC and FERC approval of the sale transaction.

Electric Rate Matters: Rate matters are critical to Consumers’ electric utility business. For additional details on rate matters, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters and Note 4, Contingencies and Commitments.

MPSC Distribution System Audit: In 2022, the MPSC ordered the state’s two largest electric utilities, including Consumers, to report on their compliance with regulations and past MPSC orders governing the utilities’ response to outages and downed lines. Consumers responded to the MPSC’s order as directed.

Additionally, as directed by the MPSC, the MPSC Staff engaged a third‑party auditor to review all equipment and operations of the two utilities’ distribution systems. In September 2024, the MPSC Staff released the third-party auditor’s final report on its audit of Consumers’ distribution system. The report included several recommendations to improve Consumers’ distribution system and associated processes and procedures. Consumers filed a response to the audit report in November 2024. In June 2025, the MPSC issued an order adopting the audit’s findings and recommendations. Consumers is committed to working with the MPSC to continue improving electric reliability and safety in Michigan.

Performance-based Financial Incentives/Disincentives Mechanism: In February 2025, the MPSC issued an order establishing a mechanism through which the state’s largest electric utilities, including Consumers, could realize up to $10 million each in incentives or penalties annually for meeting or failing to meet reliability benchmarks, beginning in 2026. As directed, Consumers filed proposed company-specific baseline metrics for the performance mechanism in April 2025; the MPSC approved Consumers’ proposed metrics in December 2025.

2025 Electric Rate Case: In June 2025, Consumers filed an application with the MPSC seeking a rate increase of $460 million, made up of two components. First, Consumers requested a $436 million annual rate increase, based on a 10.25‑percent authorized return on equity for the projected 12‑month period ending April 30, 2027. The filing requested authority to recover costs related to new infrastructure investment primarily in distribution system reliability. Second, Consumers requested approval of a $24 million surcharge for the recovery of distribution investments made during the 12 months ended February 28, 2025 that exceeded the rate amounts authorized in accordance with previous electric rate orders.

In October 2025, Consumers revised its requested increase to $447 million. Presented in the following table are the components of the revised requested increase in revenue:

In Millions

The MPSC must issue a final order in this case before or in April 2026.

Large-load Tariff: In November 2025, the MPSC approved changes to Consumers’ standard large‑customer tariff to govern service for new large electricity users such as data centers. Consumers sought these changes to protect existing customers. The changes apply to customers with a minimum service threshold of 100 MW and require a minimum 15‑year contract (beyond the construction period), an 80‑percent minimum demand billing obligation, upfront fees, and strong collateral and exit‑fee protections to ensure these large customers fully cover their own costs of service and do not shift risk or costs to existing customers. Each large-load contract must receive MPSC approval before taking effect. The MPSC also directed Consumers to present multiple cost‑allocation and rate-design options before its next rate case to ensure that large-load customers pay their fair share of system costs going forward.

Depreciation Rate Case: In December 2025, Consumers filed a depreciation case related to its electric and common utility property. In this case, Consumers requested to increase depreciation expense, and its recovery of that expense of $34 million annually based on December 31, 2024 balances.

Retention Incentive Program: The retirement of J.H. Campbell is subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy. As a result, Consumers has implemented retention measures to ensure appropriate staffing levels and expects to incur up to $4 million during each 90‑day emergency order period. Consumers will seek recovery of these retention costs from FERC, consistent with rate recovery sought for other costs of complying with the emergency orders. For additional details on this program, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 20, Exit Activities and Asset Sales. For additional details on the emergency orders, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

Electric Environmental Outlook: Consumers’ electric operations are subject to various federal, state, and local environmental laws and regulations. Consumers estimates that it will incur capital expenditures of $245 million from 2026 through 2030 to continue to comply with RCRA, the Clean Air Act, and numerous other environmental regulations. Consumers expects to recover these costs in customer rates, but cannot guarantee this result. Multiple environmental laws and regulations are subject to litigation. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters.

Air Quality: Multiple air quality regulations apply, or may apply, to Consumers’ electric utility.

MATS, emission standards for electric generating units published by the EPA based on Section 112 of the Clean Air Act, continue to apply to Consumers. In June 2025, the EPA issued a proposed rule to repeal changes made to the MATS rule in 2024. The company has complied, and continues to comply, with the MATS regulation and both the 2024 and proposed 2025 versions of MATS have minimal impacts on Consumers’ electric generating units. Consumers does not expect MATS to materially impact its environmental strategy.

CSAPR requires Michigan and many other states to improve air quality by reducing power plant emissions that, according to EPA modeling, contribute to ground-level ozone in other downwind states. Consumers complies with this regulation and expects it to have minimal financial and operational impact in the near and/or long term.

In 2015, the EPA lowered the NAAQS for ozone and made it more difficult to construct or modify power plants and other emission sources in areas of the country that do not meet the ozone standard. As of 2023, three counties in western Michigan have been designated as not meeting the ozone standard. Based on recent data, the EPA reclassified these counties from “moderate” to “serious” nonattainment. Additionally, a December 2025 court decision vacated the EPA’s 2023 redesignation of a seven‑county area in southeast Michigan from moderate ozone nonattainment to attainment. None of Consumers’ fossil-fuel-fired generating units are located in these areas. Consumers will continue to monitor the impact of the recent court decision on the seven-county area in southeast Michigan, including resulting agency actions, but does not anticipate it will have any impact on Consumers’ generating assets.

In March 2024, the EPA published a lower fine particulate matter NAAQS, which could result in newly designated nonattainment areas in Michigan starting in 2026. In 2025, EGLE proposed nonattainment areas for Kalamazoo and Wayne counties, with a decision by the EPA expected in 2026. Consumers does not have any fossil-fuel-fired generating assets in these counties and therefore does not expect this rule to have significant impacts on its existing generating assets or its clean energy strategy. Consumers will continue to monitor NAAQS rulemakings and litigation to evaluate potential impacts to its generating assets.

In January 2026, the EPA published a final rule amending new source performance standards for new, modified, and reconstructed stationary combustion turbines to lower emission limits for NOx. This final rule requires new large simple-cycle turbine units with higher capacity factors to install control equipment for NOx emissions. Consumers is evaluating this rule to determine its impact.

Consumers continues to evaluate these rules in conjunction with other EPA and EGLE rulemakings, litigation, executive orders, treaties, and congressional actions. This evaluation could result in:

• a change in Consumers’ fuel mix
• changes in the types of generating units Consumers may purchase or build in the future
• changes in how certain units are operated, including the installation of additional emission control equipment
• the retirement, mothballing, extended operation, or repowering with an alternative fuel of some of Consumers’ generating units
• changes in Consumers’ environmental compliance costs
• the purchase or sale of emission allowances

Greenhouse Gases: There have been numerous legislative, executive, and regulatory initiatives at the state, regional, national, and international levels that involve the potential regulation and reporting of greenhouse gases. Consumers continues to monitor and comment on these initiatives, as appropriate.

In September 2025, the EPA proposed a rule to reconsider the Greenhouse Gas Reporting Program by eliminating the reporting obligations from numerous emission sources, including Consumers’ electric generation sites and distribution equipment. Reporting of carbon dioxide to the EPA, however, will continue for sources subject to the Clean Air Act Acid Rain Program, which includes Consumers’ fossil-fuel-fired electric generation. This change could result in inconsistent approaches in voluntary greenhouse gas accounting for industrial sources.

In April 2024, the EPA finalized its rule under Section 111 of the Clean Air Act to address greenhouse gas emissions from new combustion turbine electric generating units and existing coal-, gas-, and oil‑fueled steam electric generating units. These rules do not address existing combustion turbine electric generating units. In June 2025, the EPA issued a proposed rule containing two different pathways to rescind these requirements. Consumers does not expect these proposed changes will have a significant impact on its existing gas- and oil-fueled steam electric generating assets. Consumers will continue to follow the EPA rules that address greenhouse gas emissions and will continue to evaluate potential impacts to its operations.

Increased frequency or intensity of severe or extreme weather events, including those due to climate change, could materially impact Consumers’ facilities, energy sales, and results of operations. Consumers is unable to predict these events; however, Consumers evaluates the potential physical impacts of climate change on its operations, including increased frequency or intensity of storm activity; increased precipitation; increased temperature; and changes in lake and river levels. Consumers released a report addressing the physical risks of climate change on its infrastructure in 2022. Consumers is taking steps to mitigate these risks as appropriate.

While Consumers cannot predict the outcome of changes in U.S. policy or of other legislative, executive, or regulatory initiatives involving the potential regulation or reporting of greenhouse gases, it intends to move forward with its compliance with Michigan’s clean energy requirements, its own sustainability goals, and its emphasis on reliable and resilient electric supply. Litigation, international treaties, executive orders, federal laws and regulations (including regulations by the EPA), and state laws and regulations, if enacted or ratified, could ultimately impact Consumers. Consumers may be required to:

• replace equipment
• install additional emission control equipment
• purchase emission allowances or credits (including potential greenhouse gas offset credits)
• curtail operations or modify existing facility retirement schedules
• arrange for alternative sources of supply
• purchase or build facilities that generate fewer emissions
• mothball, sell, or retire facilities that generate certain emissions
• pursue energy efficiency or demand response measures more swiftly
• take other steps to manage, sequester, or lower the emission of greenhouse gases

Although associated capital or operating costs relating to greenhouse gas regulation or legislation could be material and cost recovery cannot be assured, Consumers expects to recover these costs in rates consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.

CCRs: In 2015, the EPA published a rule regulating CCRs under RCRA. This rule adopts minimum standards for the disposal of non‑hazardous CCRs in CCR landfills and surface impoundments and criteria for the beneficial use of CCRs. The rule also sets out conditions under which some CCR units would be forced to cease receiving CCRs and related process water and to initiate closure. Due to continued litigation, many aspects of the rule have been remanded to the EPA, resulting in more proposed and final rules.

In May 2024, the EPA finalized a rule regulating legacy CCR surface impoundments and CCR management units in response to litigation that exempted inactive impoundments at inactive facilities from the 2015 CCR rule. The new rule adopts minimum standards for impoundments at electric generating facilities that became inactive before the 2015 CCR rule’s effective date. During 2024, owners and operators were required to assess whether an inactive facility contains a legacy surface impoundment and then, for identified locations, proceed with the compliance schedule.

Additionally, the EPA established groundwater monitoring, corrective action, closure, and post-closure care requirements for CCR surface impoundments and landfills closed prior to the effective date of the 2015 CCR rule, but that do not meet the closure technical and performance standards of the May 2024 rule. These include inactive CCR landfills that were previously exempted from regulation but that are now considered CCR management units. Owners are required to conduct an evaluation at active facilities or any inactive facilities with at least one legacy impoundment to identify CCR management units and determine an appropriate course of action (closure, groundwater treatment, etc.) for each identified unit according to established compliance milestone schedules. In February 2026, the EPA issued a final rule extending the compliance milestone schedule for CCR management units. This extension does not have a material impact on Consumers’ compliance strategy.

Separately, Congress passed legislation in 2016 allowing participating states to develop permitting programs for CCRs under RCRA Subtitle D. The EPA was granted authority to review these permitting programs to determine if permits issued under the proposed program would be as protective as the federal rule. Once approved, permits issued from an authorized state would serve as the basis for compliance, replacing the requirement to self-certify each aspect of the 2015 CCR rule.

Consumers, with agreement from EGLE, completed the work necessary to initiate closure by excavating CCRs or placing a final cover over each of its relevant CCR units prior to the closure initiation deadline set forth in the 2015 CCR rule. Consumers has historically been authorized to recover in electric rates costs related to coal ash disposal sites that supported power generation. Consumers completed an assessment of inactive facilities as required by the 2024 CCR rule, and did not identify any legacy impoundments. Consumers is continuing evaluations related to CCR management units and 2024 CCR rule impacts on the state permit program.

Water: Multiple water-related regulations apply, or may apply, to Consumers.

The EPA regulates cooling water intake systems of existing electric generating plants under Section 316(b) of the Clean Water Act. The rules seek to reduce alleged harmful impacts on aquatic organisms, such as fish. In 2018, Consumers submitted to EGLE studies and recommended plans to comply with Section 316(b) for its coal-fueled units but has not yet received final approval.

The EPA also regulates the discharge of wastewater through its effluent limitation guidelines for steam electric generating plants. Consumers has submitted the appropriate notices of planned participation in compliance with this rule. Consumers has also submitted timely NPDES permit applications and will be working with EGLE to incorporate applicable provisions during the permit renewal process.

Many of Consumers’ facilities maintain NPDES permits, which are vital to the facilities’ operations. Consumers applies for renewal of these permits every five years. Failure of EGLE to renew any NPDES permit, a successful appeal against a permit, a change in the interpretation or scope of NPDES permitting, or onerous terms contained in a permit could have a significant detrimental effect on the operations of a facility.

Protected Wildlife: Multiple regulations apply, or may apply, to Consumers relating to protected species and habitats.

Statutes like the federal Endangered Species Act, the Migratory Bird Treaty Act, and the Bald and Golden Eagle Protection Act of 1940 and changes to permitting may impact operations at Consumers’ facilities. In February 2024, the U.S. Fish and Wildlife Service published a final rule providing for bald eagle general permits for qualifying wind farms and electric distribution systems. Consumers has received, or is pursuing, bald eagle general permits for all its wind farms. While any resulting permitting and monitoring fees and/or restrictions on operations could impact Consumers’ existing and future operations, Consumers does not expect any material changes to its environmental strategy or Electric Supply Plan as a result of this rule.

Additionally, Consumers regularly monitors proposed changes to the listing status of several species within its operational area. A change in species listed under the Endangered Species Act, or under Michigan’s equivalent law, may impact Consumers’ costs to mitigate its impact on protected species and habitats at certain existing facilities as well as siting choices for new facilities.

Other Matters: Other electric environmental matters could have a material impact on Consumers’ outlook. For additional details on other electric environmental matters, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments—Consumers Electric Utility Contingencies—Electric Environmental Matters.

Consumers Gas Utility Outlook and Uncertainties

Gas Deliveries: Consumers’ gas customer deliveries are seasonal. The peak demand for natural gas occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel.

Over the next five years, Consumers expects weather-normalized gas deliveries to remain stable relative to 2025. This outlook reflects modest growth in gas demand, offset by the effects of energy waste reduction programs. Actual delivery levels will depend on:

• weather fluctuations
• use by power producers
• availability and development of renewable energy sources
• gas price changes
• Michigan’s economic conditions, including population trends and housing activity
• the price or demand of competing energy sources or fuels
• energy efficiency and conservation impacts

Gas Rate Matters: Rate matters are critical to Consumers’ gas utility business. For additional details on rate matters, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters and Note 4, Contingencies and Commitments.

2025 Gas Rate Case: In December 2025, Consumers filed an application with the MPSC seeking an annual rate increase of $240 million based on a 10.25‑percent authorized return on equity for the projected 12‑month period ending October 31, 2027.

Presented in the following table are the components of the requested increase in revenue:

In Millions

The MPSC must issue a final order in this case before or in October 2026.

Gas Pipeline and Storage Integrity and Safety: Consumers’ gas operations are governed by federal and state pipeline safety rules, and there are robust processes and procedures in place to maintain compliance with these regulations. The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration has published various rules that revise federal safety standards for gas transmission pipelines and underground storage facilities. Consumers has implemented measures to achieve compliance with the revised rules. There are also proposed rules expanding requirements for gas safety, although these rules are subject to reconsideration by the current administration. Under the proposed rules, Consumers will incur increased capital and increased operating and maintenance costs to install and remediate pipelines and to expand inspections, maintenance, and monitoring of existing pipelines and storage facilities.

Although associated capital or operating and maintenance costs relating to these regulations could be material and cost recovery cannot be assured, Consumers expects to recover such costs in rates consistent with the recovery of other reasonable costs of complying with laws and regulations.

Gas Environmental Outlook: Consumers expects to incur response activity costs at a number of sites, including 23 former MGP sites. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments—Consumers Gas Utility Contingencies.

Consumers’ gas operations are subject to various federal, state, and local environmental laws and regulations. Multiple environmental laws and regulations are subject to litigation. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters.

Air Quality: Multiple air quality regulations apply, or may apply, to Consumers’ gas utility.

In 2015, the EPA lowered the NAAQS for ozone and made it more difficult to construct or modify natural gas compressor stations and other emission sources in areas of the country that do not meet the ozone standard. As of 2023, three counties in western Michigan have been designated as not meeting the ozone standard. Based on recent data, the EPA reclassified these counties from “moderate” to “serious” nonattainment, which has more stringent requirements. One of Consumers’ compressor stations is in a serious ozone nonattainment area. Consequently, Consumers has initiated plans to retrofit equipment at this compressor station to lower NOx emissions.

Additionally, a December 2025 court decision vacated the EPA’s 2023 redesignation of the seven‑county area in southeast Michigan from moderate ozone nonattainment to attainment. Four of Consumers’ compressor stations are located in these counties, with one station having assets that may be impacted by the redesignation change. Consumers will continue to monitor the recent court decision’s impact on the seven-county area in southeast Michigan, including resulting agency actions, and the potential impacts to compressor station assets.

Consumers will continue to monitor NAAQS rulemakings and litigation, and evaluate potential impacts to its compressor stations and other applicable natural gas storage and delivery assets.

In March 2024, the EPA published a lower fine particulate matter NAAQS, which could result in newly designated nonattainment areas in Michigan starting in 2026. In 2025, EGLE proposed nonattainment areas for Kalamazoo and Wayne counties, with a decision by the EPA expected in 2026. Consumers has one compressor station located in Wayne County and will continue to monitor NAAQS rulemakings and litigation to evaluate potential impacts to the natural gas compressor station assets.

Greenhouse Gases: Some interest exists at the various levels of government in regulating greenhouse gases or their sources. Future regulations, if adopted, may involve requirements to reduce methane emissions from Consumers’ gas utility operations and carbon dioxide emissions from customer use of natural gas. Consumers will continue to monitor such potential rules for impacts.

In September 2025, the EPA proposed a rule to reconsider the Greenhouse Gas Reporting Program by removing the natural gas distribution segment from the reporting obligations under the petroleum and natural gas source category, and proposed to delay the reporting obligations until 2034 for the remaining sources in this category. If this proposal is finalized as proposed, it could result in inconsistent approaches in voluntary greenhouse gas accounting for industrial sources.

Consumers is making voluntary efforts to reduce its gas utility’s methane emissions. Under its Methane Reduction Plan, Consumers has set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent from 2012 baseline levels by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will likely be offset through clean fuel alternatives or nature-based carbon removal pathways. To date, Consumers has reduced methane emissions by more than 40 percent.

Consumers has also set a goal to reduce customer greenhouse gas emissions by 25 percent by 2035. Consumers’ Natural Gas Delivery Plan, a rolling ten‑year investment plan to deliver safe, reliable, clean, and affordable natural gas to customers, outlines ways in which Consumers can make early progress toward these goals in a cost-effective manner, including energy waste reduction, carbon offsets, and renewable natural gas supply.

Consumers has already initiated work in these key areas by continuing to expand its energy waste reduction targets and by offering gas customers the ability to offset their carbon footprint associated with natural gas use by purchasing renewable natural gas and/or carbon credits associated with Michigan forest preservation. Consumers has renewable natural gas facilities under construction scheduled for commercial operation in 2026 and is monitoring regulatory developments and market conditions closely as part of its ongoing evaluation of the projects. As part of this evaluation, two early‑phase renewable natural gas development projects have been paused indefinitely, and Consumers recognized an impairment charge of $15 million related to these projects in 2025. Consumers is evaluating and monitoring newer technologies to determine their role in achieving Consumers’ interim and long-term net-zero goals, including biofuels, geothermal, synthetic methane, carbon capture sequestration systems, and other innovative technologies.

NorthStar Clean Energy Outlook and Uncertainties

CMS Energy’s primary focus with respect to its NorthStar Clean Energy businesses is to maximize the value of generating assets representing 1,665 MW of capacity, and to pursue opportunities for the development of renewable generation projects, including leveraging strategic partnerships and available tax incentives.

In December 2025, NorthStar Clean Energy sold a Class A membership interest in BG Solar Holdings to a tax equity investor. BG Solar Holdings is the holding company of a 200-MW solar generation project being constructed in Branch County, Michigan. All of the project’s nameplate capacity has been committed under a 15‑year renewable energy purchase agreement. The tax equity investor contributed $15 million and recognized a deemed contribution of $35 million associated with BG Solar Holdings’ sale of investment tax credits related to a portion of the project placed into service for tax purposes in 2025. The tax equity investor will contribute additional amounts upon commercial operation of the project in 2026.

NorthStar Clean Energy retained a Class B membership interest in BG Solar Holdings. Earnings, tax attributes, and cash flows generated by BG Solar Holdings will be allocated among and distributed to the membership classes in accordance with the ratios specified in the associated limited liability company operating agreement; these ratios change over time and are not representative of the ownership interest percentages of each membership class. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 19, Variable Interest Entities.

Trends, uncertainties, and other matters related to NorthStar Clean Energy that could have a material impact on CMS Energy’s consolidated income, cash flows, or financial position include:

• investment in and financial benefits received from renewable energy and energy storage projects, including changes to tax and trade policy
• delays or difficulties in financing, constructing, and developing projects, including those arising from the performance of contractors, suppliers, or other counterparties
• changes in energy, capacity, and other commodity prices
• severe weather events and climate change associated with increasing levels of greenhouse gases
• changes in various environmental laws, regulations, principles, or practices, or in their interpretation
• indemnity obligations assumed in connection with ownership interests in facilities that involve tax equity financing
• representations, warranties, and indemnities provided in connection with sales of assets
• delays or difficulties in obtaining environmental permits

For additional details regarding NorthStar Clean Energy’s uncertainties, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments—Guarantees.

NorthStar Clean Energy Environmental Outlook: NorthStar Clean Energy’s operations are subject to various federal, state, and local environmental laws and regulations. Multiple environmental laws and regulations are subject to litigation. NorthStar Clean Energy’s primary environmental compliance focus includes, but is not limited to, the following matters.

CSAPR requires Michigan and many other states to improve air quality by reducing power plant emissions that, according to EPA modeling, contribute to ground-level ozone in other downwind states. NorthStar Clean Energy complies with this regulation and expects it to have minimal financial and operational impact in the near and/or long term.

In March 2024, the EPA published a lower fine particulate matter NAAQS, which could result in newly designated nonattainment areas in Michigan starting in 2026. In 2025, EGLE proposed nonattainment areas for Kalamazoo and Wayne counties, with a decision by the EPA expected in 2026. NorthStar Clean Energy has two fossil-fuel-fired generating units in these counties and therefore will continue to monitor NAAQS rulemaking and litigation to evaluate potential impacts to its generating assets.

In January 2026, the EPA published a final rule amending new source performance standards for new, modified, and reconstructed stationary combustion turbines to lower emission limits for NOx. This final rule requires new large simple-cycle turbine units with higher capacity factors to install control equipment for NOx emissions. NorthStar Clean Energy will monitor this rulemaking.

A December 2025 court decision vacated the EPA’s 2023 redesignation of the seven‑county area in southeast Michigan from moderate ozone nonattainment to attainment. NorthStar Clean Energy has one electric generating station located within this area. NorthStar Clean Energy will continue to monitor the recent court decision’s impact on the seven-county area in southeast Michigan, including resulting agency actions, and the potential impacts to compressor station assets.

For additional details regarding the ozone NAAQS, see Consumers Electric Utility Outlook and Uncertainties—Electric Environmental Outlook.

In September 2025, the EPA proposed a rule to reconsider the Greenhouse Gas Reporting Program by eliminating the reporting obligations from numerous emission sources. Reporting of carbon dioxide to the

EPA, however, will continue for sources subject to the Clean Air Act Acid Rain Program. This change could result in inconsistent approaches in voluntary greenhouse gas accounting for industrial sources.

In April 2024, the EPA finalized its rule under Section 111 of the Clean Air Act to address greenhouse gas emissions from new combustion turbine electric generating units and existing coal-, gas-, and oil‑fueled steam electric generating units. These rules do not address existing combustion turbine electric generating units. In June 2025, the EPA issued a proposed rule containing two different pathways to rescind these requirements. Neither pathway impacts NorthStar Clean Energy’s existing facilities. NorthStar Clean Energy will continue to follow the EPA rules that address greenhouse gas emissions and will continue to evaluate potential impacts to its operations.

Many of NorthStar Clean Energy’s facilities maintain NPDES permits, which are vital to the facilities’ operations. NorthStar Clean Energy applies for renewal of these permits every five years. Failure of EGLE to renew any NPDES permit, a successful appeal against a permit, a change in the interpretation or scope of NPDES permitting, or onerous terms contained in a permit could have a significant detrimental effect on the operations of a facility.

Other Outlook and Uncertainties

Tax Legislation: CMS Energy and Consumers are subject to changing tax laws. In July 2025, President Trump signed into law the OBBBA. The legislation allows for the immediate expensing of domestic research and development costs and includes changes to clean energy tax credits enacted by the Inflation Reduction Act of 2022. While the OBBBA restores, and makes permanent, the 100‑percent bonus depreciation deduction, it also retains a provision that allows utilities to take a full deduction of interest expense in lieu of 100‑percent bonus depreciation. CMS Energy and Consumers evaluated the provisions of the OBBBA and concluded that the legislation is not expected to have a material impact on their respective financial statements. This conclusion is subject to change as additional guidance or interpretations become available.

Litigation: CMS Energy, Consumers, and certain of their subsidiaries are named as parties in various litigation matters, as well as in administrative proceedings before various courts and governmental agencies, arising in the ordinary course of business. For additional details regarding certain legal matters, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters and Note 4, Contingencies and Commitments.

Critical Accounting Estimates

The following information is important to understand CMS Energy’s and Consumers’ results of operations and financial condition. For additional accounting policies, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 1, Significant Accounting Policies.

In the preparation of CMS Energy’s and Consumers’ consolidated financial statements, estimates and assumptions are used that may affect reported amounts and disclosures. CMS Energy and Consumers use accounting estimates for asset valuations, unbilled revenue, depreciation, amortization, financial and derivative instruments, employee benefits, stock-based compensation, the effects of regulation, indemnities, contingencies, and AROs. Actual results may differ from estimated results due to changes in the regulatory environment, regulatory decisions, lawsuits, competition, and other factors. CMS Energy and Consumers consider all relevant factors in making these assessments.

Accounting for the Effects of Industry Regulation: Because Consumers has regulated operations, it uses regulatory accounting to recognize the effects of the regulators’ decisions on its financial statements. Consumers continually assesses whether future recovery of its regulatory assets is probable by considering communications and experience with its regulators and changes in the regulatory environment. If Consumers determined that recovery of a regulatory asset were not probable, Consumers would be required to write off the asset and immediately recognize the expense in earnings. For additional information, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

Contingencies: CMS Energy and Consumers make judgments regarding the future outcome of various matters that give rise to contingent liabilities. For such matters, they record liabilities when they are considered probable and reasonably estimable, based on all available information. In particular, CMS Energy and Consumers are participating in various environmental remediation projects for which they have recorded liabilities. The recorded amounts represent estimates that may take into account such considerations as the number of sites, the anticipated scope, cost, and timing of remediation work, the available technology, applicable regulations, and the requirements of governmental authorities. For remediation projects in which the timing of estimated expenditures is considered reliably determinable, CMS Energy and Consumers record the liability at its net present value, using a discount rate equal to the interest rate on monetary assets that are essentially risk-free and have maturities comparable to that of the environmental liability. The amount recorded for any contingency may differ from actual costs incurred when the contingency is resolved. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 4, Contingencies and Commitments.

Income Taxes: The amount of income taxes paid by CMS Energy is subject to ongoing audits by federal, state, and foreign tax authorities, which can result in proposed assessments. An estimate of the potential outcome of any uncertain tax issue is highly judgmental. CMS Energy believes adequate reserves have been provided for these exposures; however, future results may include favorable or unfavorable adjustments to the estimated tax liabilities in the period the assessments are made or resolved or when statutes of limitation on potential assessments expire. Additionally, CMS Energy’s judgment as to the ability to recover its deferred tax assets may change. CMS Energy believes the valuation allowances related to its deferred tax assets are adequate, but future results may include favorable or unfavorable adjustments. As a result, CMS Energy’s effective tax rate may fluctuate significantly over time. For additional details, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 13, Income Taxes.

Pension and OPEB: CMS Energy and Consumers provide retirement pension benefits to certain employees under non‑contributory DB Pension Plans, and they provide postretirement health and life benefits to qualifying retired employees under an OPEB Plan.

CMS Energy and Consumers record liabilities for pension and OPEB on their consolidated balance sheets at the present value of the future obligations, net of any plan assets. The calculation of the liabilities and associated expenses requires the expertise of actuaries, and requires many assumptions, including:

• life expectancies
• discount rates
• expected long-term rate of return on plan assets
• rate of compensation increases
• expected health care costs

A change in these assumptions could change significantly CMS Energy’s and Consumers’ recorded liabilities and associated expenses.

Presented in the following table are estimates of credits and cash contributions through 2028 for the DB Pension Plans and OPEB Plan. Actual future costs, credits, and contributions will depend on future investment performance, discount rates, and various factors related to the participants of the DB Pension Plans and OPEB Plan. CMS Energy and Consumers will, at a minimum, contribute to the plans as needed to comply with federal funding requirements.

In Millions

1Consumers’ pension and OPEB costs are recoverable through its general ratemaking process.

Lowering the expected long-term rate of return on the assets of the DB Pension Plans by 25 basis points would increase estimated pension cost for 2026 by $8 million for both CMS Energy and Consumers. Lowering the PBO discount rates by 25 basis points would decrease estimated pension cost for 2026 by $1 million for both CMS Energy and Consumers. Pension and OPEB costs above or below the amounts used to set existing rates will be deferred as a regulatory asset or liability in accordance with Consumers’ postretirement benefits expense deferral mechanism; for more information, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 3, Regulatory Matters.

Pension and OPEB plan assets are accounted for and disclosed at fair value. Fair value measurements incorporate assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. Development of these assumptions may require judgment.

For additional details on postretirement benefits, including the fair value measurements for the assets of the DB Pension Plans and OPEB Plan, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 11, Retirement Benefits.

Unbilled Revenues: Consumers’ customers are billed monthly in cycles having billing dates that do not generally coincide with the end of a calendar month. This results in customers having received electricity or natural gas that they have not been billed for as of the month-end. Consumers estimates its unbilled revenues by applying an average billed rate to total unbilled deliveries for each customer class. Consumers records unbilled revenues as accounts receivable and accrued revenue on its consolidated balance sheet. For additional information on unbilled revenues, see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 15, Revenue.

New Accounting Standards

For details regarding new accounting standards issued but not yet effective, See Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 2, New Accounting Standards.

CMS Energy and Consumers are exposed to market risks including, but not limited to, changes in interest rates, commodity prices, and investment security prices. They may enter into various risk management contracts to mitigate exposure to these risks, including swaps, options, futures, and forward contracts. CMS Energy and Consumers enter into these contracts using established policies and procedures, under the direction of an executive oversight committee consisting of certain officers and a risk committee consisting of those and other officers and business managers.

The following risk sensitivity illustrates the potential loss in fair value, cash flows, or future earnings from financial instruments, assuming a hypothetical adverse change in market rates or prices of 10 percent. Potential losses could exceed the amounts shown in the sensitivity analyses if changes in market rates or prices were to exceed 10 percent.

Long-term Debt: CMS Energy and Consumers are exposed to interest-rate risk resulting from issuing fixed-rate and variable-rate debt instruments. CMS Energy and Consumers use a combination of these instruments, and may also enter into interest-rate swap agreements, in order to manage this risk and to achieve a reasonable cost of capital.

Presented in the following table is a sensitivity analysis of interest-rate risk on CMS Energy’s and Consumers’ debt instruments (assuming an adverse change in market interest rates of 10 percent):

In Millions

The fair value losses in the above table could be realized only if CMS Energy and Consumers transferred all of their fixed-rate financing to other creditors. The annual earnings exposure related to variable-rate financing was immaterial for both CMS Energy and Consumers at December 31, 2025 and 2024, assuming an adverse change in market interest rates of 10 percent. For additional details on financial instruments see Item 8. Financial Statements and Supplementary Data—Notes to the Consolidated Financial Statements—Note 7, Financial Instruments.

CMS Energy

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures: Under the supervision and with the participation of management, including its CEO and CFO, CMS Energy conducted an evaluation of its disclosure controls and procedures (as such term is defined in Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act). Based on such evaluation, CMS Energy’s CEO and CFO have concluded that its disclosure controls and procedures were effective as of December 31, 2025.

Management’s Annual Report on Internal Control Over Financial Reporting: CMS Energy’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Exchange Act Rules 13a‑15(f) and 15d‑15(f). CMS Energy’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP and includes policies and procedures that:

• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of CMS Energy
• provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of CMS Energy are being made only in accordance with authorizations of management and directors of CMS Energy
• provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of CMS Energy’s assets that could have a material effect on its financial statements

Management, including its CEO and CFO, does not expect that its internal controls will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. In addition, any evaluation of the effectiveness of controls is subject to risks that those internal controls may become inadequate in future periods because of changes in business conditions, or that the degree of compliance with the policies or procedures deteriorates.

Under the supervision and with the participation of management, including its CEO and CFO, CMS Energy conducted an evaluation of the effectiveness of its internal control over financial reporting as of December 31, 2025. In making this evaluation, management used the criteria set forth in the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on such evaluation, CMS Energy’s management concluded that its internal control over financial reporting was effective as of December 31, 2025. The effectiveness of CMS Energy’s internal control over financial reporting as of December 31, 2025 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their report which appears under Item 8. Financial Statements and Supplementary Data.

Changes in Internal Control Over Financial Reporting: There have not been any changes in CMS Energy’s internal control over financial reporting during the last fiscal quarter that have materially affected, or are reasonably likely to affect materially, its internal control over financial reporting.

Consumers

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures: Under the supervision and with the participation of management, including its CEO and CFO, Consumers conducted an evaluation of its disclosure controls and procedures (as such term is defined in Rules 13a‑15(e) and 15d‑15(e) under the Exchange Act).
