CMS Energy and Consumers—The Triple Bottom Line

For information regarding CMS Energy's and Consumers' purpose and impact on the "triple bottom line" of people, planet, and prosperity, see Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview.

**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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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

![265](cms-20251231_g4.jpg)

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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

![1076](cms-20251231_g5.jpg)

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 263 miles of high-voltage distribution overhead lines operating at 138 kV

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 4 miles of high-voltage distribution underground lines operating at 138 kV

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 4,619 miles of high-voltage distribution overhead lines operating at 46 kV and 69 kV

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 18 miles of high-voltage distribution underground lines operating at 46 kV

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 82,854 miles of electric distribution overhead lines

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 10,027 miles of underground distribution lines

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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.

<sup>1</sup>Represents Consumers' share of net pumped-storage generation. During 2025, the pumped-storage facility consumed 1,351 GWh of electricity to pump water during off-peak hours for storage in order to generate 991 GWh of electricity later during peak-demand hours.

<sup>2</sup>Represents purchases under long-term PPAs, including capacity purchases.

<sup>3</sup>Reflects net delivered energy from storage operations, after accounting for charging losses.

<sup>4</sup>Represents 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• aggressively controlling operating, maintenance, power supply, and fuel costs and passing savings on to customers

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• providing renewable energy options and energy waste reduction programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• providing competitive rate-design options, particularly for large energy-intensive customers

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• offering tariff-based incentives that support economic development

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

![251](cms-20251231_g6.jpg)

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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

![1420](cms-20251231_g7.jpg)

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 2,337 miles of transmission lines

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 14 gas storage fields with a total storage capacity of 300 Bcf and a working gas volume of 153 Bcf

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 28,433 miles of distribution mains

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

![2183](cms-20251231_g8.jpg)

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 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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhanced existing incentives for energy efficiency programs and returns earned on new clean or renewable PPAs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• created a new energy storage standard, requiring electric utilities to file plans by 2029 to help achieve a statewide target of 2,500 MW

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expanded the statutory cap on distributed generation resources to 10 percent of the electric utility's five-year average peak load

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provided the MPSC siting authority over large renewable energy projects

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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.

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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 75-percent positive sentiment for engagement, up 3 percentage points from 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 65-percent positive sentiment for empowerment, no change from 2024

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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:

---

| | | |
|:---|:---|:---|
| December 31, 2025 | CMS Energy, including<br>Consumers | Consumers |
| Percent female employees | 26% | 26% |
| Percent racially or ethnically diverse employees | 13 | 13 |

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Women in Energy, working toward an inclusive place for all women in the fields they have chosen, from front line to management

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Minority Advisory Panel, promoting a culture of diversity and inclusion among all racial and ethnic minorities through education, leadership, development, and networking

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Veterans Advisory Panel, supporting former and active military personnel and assisting in recruiting and retaining veterans through career development

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Genergy, a multigenerational group designed to bridge the gap of learning, networking, and mentoring across the generations of the workforce

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Capable, aimed at removing barriers and creating pathways to meaningful work for co-workers of all abilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

**Item 1A.&nbsp;&nbsp;&nbsp;&nbsp;Risk Factors**

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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• CMS Energy's ability to obtain additional financing for working capital, capital expenditures, acquisitions, and general corporate and other purposes could become limited

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• CMS Energy could be placed at a competitive disadvantage to its competitors that are less leveraged

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• CMS Energy's vulnerability to adverse economic and industry conditions could increase

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prevent the construction of new facilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prevent the continued operation of and sale of energy from existing facilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• modify the way in which a facility is operated

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prevent the suspension of operations at existing facilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prevent the modification of existing facilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effective pre-acquisition evaluation of asset values, future operating costs, potential environmental and other liabilities, and other factors beyond Consumers' control

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effective cost and schedule management of new capital projects

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• availability of qualified construction personnel, both internal and contracted

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effective and timely contractor performance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in commodity and other prices, applicable tariffs, and/or material and equipment availability

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• governmental actions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interconnection uncertainty, delays, and costs for electric generation projects

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operational performance

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in environmental, legislative, and regulatory requirements

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory cost recovery

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inflation of labor rates and material and equipment prices

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• supply chain disruptions and increased lead times

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• retain specified preexisting liabilities, such as for taxes, pensions, or environmental conditions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• indemnify the buyers against specified risks, including the inaccuracy of representations and warranties that CMS Energy and Consumers make

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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.

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

**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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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.

**Item 1B.&nbsp;&nbsp;&nbsp;&nbsp;Unresolved Staff Comments**

None.

**Item 1C.&nbsp;&nbsp;&nbsp;&nbsp;Cybersecurity**

**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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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.

**Item 7.&nbsp;&nbsp;&nbsp;&nbsp;Management's Discussion and Analysis of Financial Condition and Results of Operations**

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulation and regulatory matters

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• state and federal legislation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• economic conditions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• load growth

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• weather

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• energy commodity prices

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interest rates

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

![Strategy on a Page.jpg](cms-20251231_g10.jpg)

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• targeted infrastructure investment to reduce maintenance costs and improve reliability and safety

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• supply chain optimization

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• economic development to increase sales and reduce overall rates

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• information and control system efficiencies

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• employee and retiree health care cost sharing

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax planning

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cost-effective financing

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced carbon dioxide emissions from owned generation by nearly 30 percent since 2005

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced methane emissions by more than 40 percent since 2012

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced the volume of water used to generate electricity by nearly 60 percent since 2012

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced landfill waste disposal by more than 2 million tons since 1992

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhanced, restored, or protected more than 13,500 acres of land since 2017

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced sulfur dioxide and particulate matter emissions by more than 90 percent since 2005

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced NOx emissions by more than 85 percent since 2005

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced mercury emissions by more than 90 percent since 2007

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

![549755819672](cms-20251231_g11.jpg)

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enhanced existing incentives for energy efficiency programs and returns earned on new clean or renewable PPAs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• created a new energy storage standard, requiring electric utilities to file plans by 2029 to help achieve a statewide target of 2,500 MW

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

![862](cms-20251231_g12.jpg)

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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

*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:

**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

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increased the renewable energy standard from 15 percent to 50 percent by 2030 and 60 percent by 2035

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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:

![7112](cms-20251231_g13.jpg)

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>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• energy conservation measures and results of energy waste reduction programs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• weather fluctuations

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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* | *In Millions* |
| Projected 12-Month Period Ending April 30 | 2027 |
| Investment in rate base | $192 |
| Operating and maintenance costs | 157 |
| Cost of capital | 67 |
| Sales and other revenue | 7 |
| Subtotal | $423 |
| Surcharge | 24 |
| Total | $447 |

---

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

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

*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'

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a change in Consumers' fuel mix

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the types of generating units Consumers may purchase or build in the future

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in how certain units are operated, including the installation of additional emission control equipment

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the retirement, mothballing, extended operation, or repowering with an alternative fuel of some of Consumers' generating units

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in Consumers' environmental compliance costs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• replace equipment

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• install additional emission control equipment

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchase emission allowances or credits (including potential greenhouse gas offset credits)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• curtail operations or modify existing facility retirement schedules

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• arrange for alternative sources of supply

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchase or build facilities that generate fewer emissions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• mothball, sell, or retire facilities that generate certain emissions

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pursue energy efficiency or demand response measures more swiftly

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• weather fluctuations

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• use by power producers

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• availability and development of renewable energy sources

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• gas price changes

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Michigan's economic conditions, including population trends and housing activity

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the price or demand of competing energy sources or fuels

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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* | *In Millions* |
| Projected 12-Month Period Ending October 31 | 2027 |
| Investment in rate base | $108 |
| Operating and maintenance costs | 65 |
| Cost of capital | 66 |
| Sales/gross margin | 1 |
| Total | $240 |

---

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.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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.

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• investment in and financial benefits received from renewable energy and energy storage projects, including changes to tax and trade policy

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delays or difficulties in financing, constructing, and developing projects, including those arising from the performance of contractors, suppliers, or other counterparties

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in energy, capacity, and other commodity prices

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• severe weather events and climate change associated with increasing levels of greenhouse gases

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in various environmental laws, regulations, principles, or practices, or in their interpretation

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• indemnity obligations assumed in connection with ownership interests in facilities that involve tax equity financing

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• representations, warranties, and indemnities provided in connection with sales of assets

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• life expectancies

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• discount rates

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expected long-term rate of return on plan assets

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• rate of compensation increases

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

<sup>1</sup>Consumers' 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.

**Item 7A.&nbsp;&nbsp;&nbsp;&nbsp;Quantitative and Qualitative Disclosures About Market Risk**

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* | *In Millions* | *In Millions* |
| December 31 | 2025 | 2024 |
| *Fixed-rate financing—potential loss in fair value* |  |  |
| &nbsp;&nbsp;CMS Energy, including Consumers | $792 | $717 |
| &nbsp;&nbsp;Consumers | 535 | 543 |

---

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 Corporation

Consumers Energy Company

**Notes to the Consolidated Financial Statements**

**1:&nbsp;&nbsp;&nbsp;&nbsp;Significant Accounting Policies**

**Principles of Consolidation:** CMS Energy and Consumers prepare their consolidated financial statements in conformity with GAAP. CMS Energy's consolidated financial statements comprise CMS Energy, Consumers, NorthStar Clean Energy, and all other entities in which CMS Energy has a controlling financial interest or is the primary beneficiary. Consumers' consolidated financial statements comprise Consumers and all other entities in which it has a controlling financial interest. CMS Energy uses the equity method of accounting for investments in companies and partnerships that are not consolidated, where they have significant influence over operations and financial policies but are not the primary beneficiary. CMS Energy and Consumers eliminate intercompany transactions and balances.

**Use of Estimates:** CMS Energy and Consumers are required to make estimates using assumptions that may affect reported amounts and disclosures. Actual results could differ from those estimates.

**Cash and Cash Equivalents and Restricted Cash and Cash Equivalents:** Cash and cash equivalents include short-term, highly liquid investments with original maturities of three months or less. Restricted cash and cash equivalents are held primarily for the repayment of securitization bonds and funds held in escrow. These amounts are classified as current assets since they relate to payments that could or will occur within one year.

**Contingencies:** CMS Energy and Consumers record estimated loss contingencies on their consolidated financial statements when it is probable that a loss has been incurred and when the amount of loss can be reasonably estimated. For environmental 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. Unless regulatory accounting applies, CMS Energy and Consumers expense legal fees as incurred; fees incurred but not yet billed are accrued based on estimates of work performed.

**Debt Issuance Costs, Discounts, Premiums, and Refinancing Costs:** Upon the issuance of long-term debt, CMS Energy and Consumers defer issuance costs, discounts, and premiums and amortize those amounts over the terms of the associated debt. Debt issuance costs are presented as a direct deduction from the carrying amount of long-term debt on the balance sheet. Upon the refinancing of long-term debt, Consumers, as a regulated entity, defers any remaining unamortized issuance costs, discounts, and premiums associated with the refinanced debt and amortizes those amounts over the term of the newly issued debt. For the non-regulated portions of CMS Energy's business, any remaining unamortized issuance costs, discounts, and premiums associated with extinguished debt are charged to earnings.

**Derivative Instruments:** In order to support ongoing operations, CMS Energy and Consumers may enter into contracts for the future purchase and sale of various commodities, such as electricity, natural gas, and coal. These forward contracts are generally long-term in nature and result in physical delivery of the

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

commodity at a contracted price. Most of these contracts are not subject to derivative accounting for one or more of the following reasons:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• they do not have a notional amount (that is, a number of units specified in a derivative instrument, such as MWh of electricity or Bcf of natural gas)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• they qualify for the normal purchases and sales exception

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• they cannot be net settled due in part to the absence of an active market for the commodity

Consumers also uses FTRs to manage price risk related to electricity transmission congestion. An FTR is a financial instrument that entitles its holder to receive compensation or requires its holder to remit payment for congestion-related transmission charges. Consumers accounts for FTRs as derivatives and changes in the fair value of FTRs are deferred as regulatory assets or liabilities. For details regarding CMS Energy's and Consumers' derivative instruments recorded at fair value, see Note 6, Fair Value Measurements.

**Electricity Market Transactions:** Wholesale electricity market operators require the submission of hourly day-ahead and real-time bids and offers for energy at locations across each region. CMS Energy and Consumers account for such transactions on a net hourly basis in each of the real-time and day-ahead markets, netted across all locations in the energy market. CMS Energy and Consumers record net hourly purchases in purchased and interchange power and net hourly sales in operating revenue on their consolidated statements of income. They record net billing adjustments upon receipt of settlement statements, record accruals for future net purchases and sales adjustments based on historical experience, and reconcile accruals to actual expenses and sales upon receipt of settlement statements.

**EPS:** CMS Energy calculates basic and diluted EPS using the weighted-average number of shares of common stock and dilutive potential common stock outstanding during the period. Potential common stock, for purposes of determining diluted EPS, includes the effects of nonvested stock awards, forward equity sales, and convertible securities. CMS Energy computes the effect on potential common stock using the treasury stock method. Potentially dilutive common shares issuable upon conversion of the convertible senior notes are determined using the if-converted method for calculating diluted EPS. Diluted EPS excludes the impact of antidilutive securities, which are those securities resulting in an increase in EPS or a decrease in loss per share. For EPS computations, see Note 14, Earnings Per Share—CMS Energy.

**Impairment of Long-lived Assets and Equity Method Investments:** CMS Energy and Consumers perform tests of impairment if certain triggering events occur that indicate the carrying amount of an asset may not be recoverable or that there has been a decline in value that may be other than temporary.

CMS Energy and Consumers evaluate long-lived assets held in use for impairment by calculating the undiscounted future cash flows expected to result from the use of the asset and its eventual disposition. If the undiscounted future cash flows are less than the carrying amount, CMS Energy and Consumers recognize an impairment loss equal to the amount by which the carrying amount exceeds the fair value. CMS Energy and Consumers estimate the fair value of the asset using quoted market prices, market prices of similar assets, or discounted future cash flow analyses.

CMS Energy also assesses equity method investments for impairment whenever there has been a decline in value that is other than temporary. This assessment requires CMS Energy to determine the fair value of the equity method investment. CMS Energy determines fair value using valuation methodologies, including discounted cash flows, and assesses the ability of the investee to sustain an earnings capacity that justifies the carrying amount of the investment. CMS Energy records an impairment if the fair value is less than the carrying amount and the decline in value is considered to be other than temporary.

**Investment Tax Credits:** CMS Energy and its subsidiaries use the flow-through method of accounting for investment tax credits. Under the flow-through method, the credit is recognized as a reduction to income tax expense when the related plant, property, and equipment is placed into service. For its regulated utility assets, Consumers amortizes its investment tax credits over the life of the related property in accordance with regulatory treatment.

**Inventory:** CMS Energy and Consumers use the weighted-average cost method for valuing working gas, recoverable base gas in underground storage facilities, and materials and supplies inventory. CMS Energy and Consumers also use this method for valuing coal inventory, and they classify these amounts as generating plant fuel stock on their consolidated balance sheets.

CMS Energy and Consumers account for RECs and other environmental credits as inventory and use the weighted-average cost method to remove amounts from inventory. RECs and other environmental credits are used to satisfy compliance obligations related to the generation of power and in support of sustainability commitments. CMS Energy and Consumers classify these amounts within other assets on their consolidated balance sheets.

CMS Energy and Consumers evaluate inventory for impairment as required to ensure that its carrying value does not exceed the lower of cost or net realizable value.

**Property Taxes:** Property taxes are based on the taxable value of CMS Energy's and Consumers' real and personal property assessed by local taxing authorities. CMS Energy and Consumers record property tax expense over the fiscal year of the taxing authority for which the taxes are levied. The deferred property tax balance represents the amount of CMS Energy's and Consumers' accrued property tax that will be recognized over future governmental fiscal periods.

**2:&nbsp;&nbsp;&nbsp;&nbsp;New Accounting Standards**

Implementation of New Accounting Standards

*ASU 2023-09, Incomes Taxes (Topic 740): Improvements to Income Tax Disclosures:* This standard, which was effective on January 1, 2025 for CMS Energy and Consumers, requires expanded annual disclosures of the income taxes, including a more detailed reconciliation of the effective tax rate and disaggregated information on federal and state income taxes. The standard also requires disclosure of significant reconciling items and qualitative information about state and local jurisdictions contributing to income tax expense. The adoption of the new standard did not impact CMS Energy's or Consumers' liquidity, financial condition, or results of operations. The expanded disclosures required by this standard are included in Note 13, Income Taxes.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

New Accounting Standards Not Yet Effective

*ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses:* This standard requires public companies to provide disaggregated information about certain expense categories presented on the income statement. The guidance calls for annual and interim disclosures that separate specified components, such as employee compensation, depreciation, and amortization, within relevant expense line items in the notes to the financial statements. The standard is effective for annual reporting periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. CMS Energy and Consumers will adopt the guidance upon the effective date. The standard will not have an impact on CMS Energy's or Consumers' consolidated net income, cash flows, or financial position.

*ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software:* This standard updates guidance for capitalizing costs related to internal-use software development. The amendments remove references to the previous "project stage" model and clarify the threshold for when capitalization should begin, focusing on whether completion of the project is probable. The amendments are effective for annual and interim reporting periods beginning after December 15, 2027. The guidance may be applied on a prospective, retrospective, or modified transition basis. Early adoption is permitted. CMS Energy and Consumers are currently evaluating the new standard.

**3:&nbsp;&nbsp;&nbsp;&nbsp;Regulatory Matters**

Regulatory matters are critical to Consumers. 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, such as Consumers' rate cases and PSCR and GCR processes. Intervenors also participate in certain FERC matters, including FERC's regulation of certain wholesale rates that affect Consumers' power supply costs. 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. Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC and FERC orders or other actions, could negatively affect CMS Energy's and Consumers' liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings.

Regulatory Assets and Liabilities

Consumers is subject to the actions of the MPSC and FERC and therefore prepares its consolidated financial statements in accordance with the provisions of regulatory accounting. A utility must apply regulatory accounting when its rates are designed to recover specific costs of providing regulated services. Under regulatory accounting, Consumers records regulatory assets or liabilities for certain transactions that would have been treated as expense or revenue by non-regulated businesses.

<sup>1</sup>These regulatory assets have arisen from an alternative-revenue program and are not associated with incurred costs or capital investments. Therefore, the MPSC has provided for recovery without a return.

<sup>2</sup>This regulatory asset is included in rate base, thereby providing a return.

<sup>3</sup>The MPSC has provided a specific return on these regulatory assets.

<sup>4</sup>These regulatory assets represent incurred costs for which the MPSC has provided recovery without a return on investment.

Regulatory Assets

**Energy Waste Reduction Plan Incentive:** The energy waste reduction incentive mechanism provides a financial incentive if the energy savings of Consumers' customers exceed annual targets established by the MPSC. Consumers accounts for this program as an alternative-revenue program that meets the criteria for recognizing revenue related to the incentive as soon as energy savings exceed the annual targets established by the MPSC.

In January 2026, the MPSC approved a settlement agreement authorizing Consumers to collect $64 million during 2026 as an incentive for exceeding its statutory savings targets in 2024. Consumers recognized incentive revenue under this program of $64 million in 2024.

Consumers also exceeded its statutory savings targets in 2025, achieved certain other goals, and will request the MPSC's approval to collect $64 million in the energy waste reduction reconciliation to be filed in May 2026. Consumers recognized incentive revenue under this program of $64 million in 2025.

**Retention Incentive Program:** To ensure necessary staffing at the D.E. Karn and J.H. Campbell coal-fueled generating units through their retirement, Consumers established retention incentive programs. The MPSC has approved deferred accounting treatment for the retention and severance costs incurred under these programs and has allowed for recovery over three years. These MPSC-approved retention plans concluded in November 2025. For additional details regarding retention incentive programs, see Note 20, Exit Activities and Asset Sales.

**2022 PSCR Underrecovery:** As a result of rising fuel prices during 2022, Consumers' power supply costs for 2022 were significantly higher than those projected in its 2022 PSCR plan. At the end of 2022, Consumers had recorded $401 million of under-recovered power supply costs. In 2023, the MPSC authorized Consumers to recover the 2022 underrecovery amount over three years, providing immediate relief to electric customers.

**Costs of Coal-fueled Electric Generating Units to be Retired:** In 2022, the MPSC approved Consumers' plans to retire the J.H. Campbell coal-fueled generating units in 2025. The MPSC authorized regulatory asset treatment for Consumers to recover the remaining book value of the units upon their retirement, as well as a 9.0-percent return on equity, through 2040, the units' original retirement date. Accordingly, in 2022, Consumers removed from total plant, property, and equipment an amount of $1.3 billion, representing the projected remaining book value of the electric generating units upon their retirement, and recorded it as a non-current regulatory asset on its consolidated balance sheets.

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. Such orders authorize Consumers to obtain cost recovery at FERC; thus, Consumers has deferred the costs of complying with these orders as a regulatory asset.

**Postretirement Benefits:** As part of the ratemaking process, the MPSC allows Consumers to recover the costs of postretirement benefits. Accordingly, Consumers defers the net impact of actuarial losses and gains, prior service costs and credits, and settlements associated with postretirement benefits as a regulatory asset or liability. The asset or liability will decrease as the deferred items are amortized and recognized as components of net periodic benefit cost. For details about the amortization periods, see Note 11, Retirement Benefits.

**Securitized Costs:** The MPSC has issued securitization financing orders authorizing Consumers to issue securitization bonds in order to finance the recovery of the remaining book value of three smaller natural gas-fueled electric generating units that Consumers retired in 2015, seven smaller coal-fueled electric generating units that Consumers retired in 2016, and the D.E. Karn coal-fueled electric generating units that Consumers retired in 2023. Consumers has removed from plant, property, and equipment and recorded as a regulatory asset the book value of these units. Consumers is amortizing the regulatory asset over the life of the related securitization bonds, which it issued through subsidiaries in 2014 and 2023. For additional details regarding the securitization bonds, see Note 5, Financings and Capitalization—Securitization Bonds.

**ARO:** The recovery of the underlying asset investments and related removal and monitoring costs of recorded AROs is approved by the MPSC in depreciation rate cases. Consumers records a regulatory asset and a regulatory liability for timing differences between the recognition of AROs for financial reporting purposes and the recovery of these costs from customers. The recovery period approximates the useful life of the assets to be removed.

**Decommissioning Costs:** In Consumers' electric depreciation and general rate cases, the MPSC has authorized Consumers to remove from depreciation rates the costs of decommissioning the D.E. Karn coal-fueled electric generating units, and instead defer those costs as a regulatory asset to be recovered through 2031. Additionally, ash disposal costs related to Consumers' retired coal-fueled generating units may be deferred as a regulatory asset and collected over a ten-year period. In its 2022 order approving Consumers' integrated resource plan, the MPSC authorized similar treatment for the decommissioning and ash disposal costs associated with the J.H. Campbell coal-fueled generating units that were planned for retirement in 2025.

**Unamortized Loss on Reacquired Debt:** Under regulatory accounting, any unamortized discount, premium, or expense related to debt redeemed with the proceeds of new debt is deferred and amortized over the life of the new debt.

**MGP Sites:** Consumers is incurring environmental remediation and other response activity costs at 23 former MGP facilities. The MPSC allows Consumers to recover from its natural gas customers over a ten-year period the costs incurred to remediate the MGP sites. For additional information, see Note 4, Contingencies and Commitments—Consumers Gas Utility Contingencies.

**Ludington Overhaul Contract Dispute:** The MPSC has authorized Consumers to defer as a regulatory asset costs associated with correcting incomplete, nonconforming, and defective work performed by TAES during a major overhaul and upgrade of Ludington. Consumers will defer such costs while post-verdict proceedings and any appeals in the litigation with TAES and Toshiba continue; such costs will be offset, in part or in whole, by future litigation proceeds received from TAES or Toshiba. Consumers has also deferred replacement power costs due to outages resulting from correcting this work. Consumers will have the opportunity to seek appropriate recovery and ratemaking treatment for amounts recorded as a regulatory asset following resolution of the litigation. During 2025, cash expenditures associated with the Ludington overhaul contract dispute were $30 million. For additional details on the contract dispute, see Note 4, Contingencies and Commitments—Consumers Electric Utility Contingencies.

**Service Restoration Cost Deferral:** As a result of catastrophic storms in Consumers' electric service territory, Consumers incurred significant service restoration costs during March and April 2025. In April 2025, Consumers filed with the MPSC an ex parte application requesting approval to defer, as a regulatory asset, operating and maintenance expenses associated with the storms. In June 2025, the MPSC approved the application, authorizing the deferral of these expenses for accounting purposes. Recovery of this regulatory asset will be requested in a future case.

**Energy Waste Reduction Plan:** Michigan law requires electric and gas utilities to implement programs that reduce energy consumption through energy efficiency and demand-side energy conservation. Utilities may recover the cost of achieving specified reductions in customers' electricity and gas use through surcharges. The amount of spending incurred in excess of surcharges collected is recorded as a regulatory asset and amortized as surcharges are collected from customers over the plan period. The amount of surcharges collected in excess of spending incurred is recorded as a regulatory liability and amortized as costs are incurred.

**Postretirement Benefits Expense Deferral Mechanism:** In Consumers' general rate cases, the MPSC approved a mechanism allowing Consumers to defer for future recovery or refund pension and OPEB expenses above or below the amounts used to set existing rates. Amounts deferred will be collected from or refunded to customers over ten years.

**Renewable Energy Plan:** Under Michigan law, renewable energy standards specify how much electricity must come from renewable sources and which technologies, such as wind, solar, and certain biomass, qualify. Utilities may recover compliance costs, including renewable power purchases (and related financial mechanisms), depreciation, property taxes, interest, and other operating and maintenance expenses for company-owned renewable assets, along with a return on those assets. The MPSC allows Consumers to transfer and collect a portion of these costs through its PSCR process. Incremental costs may be collected through surcharges. If spending exceeds amounts collected, the difference is recorded as a regulatory asset and amortized as recovered from customers; this excludes amounts related to return on equity. If collections exceed spending, the excess is recorded as a regulatory liability and amortized as future costs are incurred for operating renewable facilities and purchasing RECs under renewable energy agreements.

Regulatory Liabilities

**Income Taxes, Net:** Consumers records regulatory assets and liabilities to reflect the difference between deferred income taxes recognized for financial reporting purposes and amounts previously reflected in Consumers' rates. This net balance will decrease over the remaining life of the related temporary differences and flow through income tax expense. The majority of the net regulatory liability recorded related to income taxes is associated with plant assets that are subject to normalization, which is governed by the Internal Revenue Code, and will be returned to customers over the remaining book life of the related plant assets. For additional details on deferred income taxes, see Note 13, Income Taxes.

**ASP Gain:** In April 2024, Consumers sold its unregulated ASP business to a non-affiliated company, resulting in a $110 million gain. In July 2024, the MPSC approved the utilization of $27.5 million, or one-fourth, of the gain on the sale as an offset to the revenue deficiency in lieu of additional rate relief during the 12-month period beginning October 1, 2024, with the remaining three-fourths of the gain, or $82.5 million, to be credited to customers as a bill credit over a three-year period beginning October 1, 2024.

**Cost of Removal:** The MPSC allows Consumers to collect amounts from customers to fund future asset removal activities. This regulatory liability is reduced as costs are incurred to remove the assets at the end of their useful lives.

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

**Green Giving Program:** In conjunction with Consumers' voluntary green pricing program, the MPSC has directed Consumers to use surplus program funds to support renewable-energy participation by low-income customers.

**Renewable Energy Grant:** In 2013, Consumers received a $69 million renewable energy grant for Lake Winds<sup>®</sup> Energy Park, which began operations in 2012. This grant reduces Consumers' cost of complying with Michigan's renewable portfolio standard and, accordingly, reduces the overall renewable energy surcharge to be collected from customers. The regulatory liability recorded for the grant will be amortized over the life of Lake Winds<sup>®</sup> Energy Park. Consumers presents the amortization as a reduction to maintenance and other operating expenses on its consolidated statements of income.

Consumers Electric Utility

**2024 Electric Rate Case:** In May 2024, Consumers filed an application with the MPSC seeking a rate increase of $325 million, made up of two components. First, Consumers requested a $303 million annual rate increase, based on a 10.25-percent authorized return on equity for the projected 12-month period ending February 28, 2026. The filing requested authority to recover costs related to new infrastructure investment primarily in distribution system reliability and cleaner energy resources. Second, Consumers requested approval of a $22 million surcharge for the recovery of distribution investments made in 2023 that exceeded the rates authorized in accordance with previous electric rate orders.

In October 2024, Consumers revised its requested increase to $277 million, primarily to reflect the removal of projected capital investments associated with certain solar facilities that Consumers incorporated into its amended Renewable Energy Plan.

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

**J.H. Campbell Emergency Order:** 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 that would enable Consumers to recover the costs of complying with the emergency orders. Consumers' complaint sought a mechanism in the MISO Tariff that would allow allocation of those compliance costs across the MISO North and Central regions, consistent with the nature of the energy emergency declared in the U.S. Secretary of Energy orders. 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.

In January 2026, Consumers filed a request at FERC seeking recovery of the net financial impact of complying with the May 2025 emergency order, which was $42 million after applying MISO revenues of $78 million. This filing encompasses recovery sought by the joint owners of J.H. Campbell.

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

For the second emergency order period through December 31, 2025, the net financial impact of compliance was $93 million after applying MISO revenues of $77 million. Consumers will seek recovery of these compliance costs at a later date, consistent with rate recovery sought for the May 2025 emergency order. The ultimate financial impact remains subject to the outcome of the FERC proceeding and any future guidance or interpretation.

Consumers Gas Utility

**2024 Gas Rate Case:** In December 2024, Consumers filed an application with the MPSC seeking an annual rate increase of $248 million based on a 10.25-percent authorized return on equity for the projected 12-month period ending October 31, 2026. In July 2025, Consumers revised its requested increase to $217 million. 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.

PSCR and GCR

The PSCR and GCR ratemaking processes are designed to allow Consumers to recover all of its power supply and purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its PSCR and GCR billing charges monthly, subject to ceiling factor limitations, in order to minimize the underrecovery or overrecovery amount in the annual reconciliations. Underrecoveries represent power supply and purchased natural gas costs that will be recovered from customers; overrecoveries represent previously collected revenues that will be refunded to customers.

Presented in the following table are the liabilities for PSCR and GCR underrecoveries and overrecoveries reflected on Consumers' consolidated balance sheets:

---

**4:&nbsp;&nbsp;&nbsp;&nbsp;Contingencies and Commitments**

CMS Energy and Consumers are involved in various matters that give rise to contingent liabilities. Depending on the specific issues, the resolution of these contingencies could negatively affect CMS Energy's and Consumers' liquidity, financial condition, and results of operations. In their disclosures of these matters, CMS Energy and Consumers provide an estimate of the possible loss or range of loss when such an estimate can be made. Disclosures stating that CMS Energy or Consumers cannot predict the outcome of a matter indicate that they are unable to estimate a possible loss or range of loss for the matter.

CMS Energy Contingencies

CMS Land retained environmental remediation obligations for the collection and treatment of leachate at Bay Harbor after selling its interests in the development in 2002. Leachate is produced when water enters into cement kiln dust piles left over from former cement plant operations at the site. In 2012, CMS Land and EGLE finalized an agreement establishing the final remedies and the future water quality criteria at the site. CMS Land completed all construction necessary to implement the remedies required by the agreement and will continue to maintain and operate a system to discharge treated leachate into Little Traverse Bay under an NPDES permit, which was valid through 2025. CMS Land submitted a renewal request in March 2025, and will continue to operate under the existing permit until a renewal is issued.

At December 31, 2025, CMS Energy had a recorded liability of $48 million for its remaining obligations for environmental remediation. CMS Energy calculated this liability based on discounted projected costs, using a discount rate of 4.34 percent and an inflation rate of 1 percent on annual operating and maintenance costs. The undiscounted amount of the remaining obligation is $62 million. CMS Energy expects to pay the following amounts for long-term leachate disposal and operating and maintenance costs in each of the next five years:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| *In Millions* | *In Millions* | *In Millions* | *In Millions* | *In Millions* | *In Millions* |
|  | 2026 | 2027 | 2028 | 2029 | 2030 |
| Long-term leachate disposal and operating and maintenance costs | $4 | $4 | $4 | $4 | $4 |

---

CMS Energy's estimate of response activity costs and the timing of expenditures could change if there are changes in circumstances or assumptions used in calculating the liability. Although a liability for its present estimate of remaining response activity costs has been recorded, CMS Energy cannot predict the ultimate financial impact or outcome of this matter.

Consumers Electric Utility Contingencies

**Electric Environmental Matters:** Consumers' operations are subject to environmental laws and regulations. Historically, Consumers has generally been able to recover, in customer rates, the costs to operate its facilities in compliance with these laws and regulations.

*Cleanup and Solid Waste:* Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA. Consumers believes that these costs should be recoverable in rates, but cannot guarantee that outcome. Consumers estimates its liability for NREPA sites for which it can estimate a range of loss to be between $2 million and $3 million. At December 31, 2025, Consumers had a recorded liability of $2 million, the minimum amount in the range of its estimated probable NREPA liability, as no amount in the range was considered a better estimate than any other amount.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

Consumers is a potentially responsible party at a number of contaminated sites administered under CERCLA. CERCLA liability is joint and several. In 2010, Consumers received official notification from the EPA that identified Consumers as a potentially responsible party for cleanup of PCBs at the Kalamazoo River CERCLA site. The notification claimed that the EPA had reason to believe that Consumers disposed of PCBs and arranged for the disposal and treatment of PCB-containing materials at portions of the site. In 2011, Consumers received a follow-up letter from the EPA requesting that Consumers agree to participate in a removal action plan along with several other companies for an area of lower Portage Creek, which is connected to the Kalamazoo River. All parties asked to participate in the removal action plan, including Consumers, declined to accept liability. Until further information is received from the EPA, Consumers is unable to estimate a range of potential liability for cleanup of the river.

Based on its experience, Consumers estimates its share of the total liability for known CERCLA sites to be between $3 million and $8 million. Various factors, including the number and creditworthiness of potentially responsible parties involved with each site, affect Consumers' share of the total liability. At December 31, 2025, Consumers had a recorded liability of $3 million for its share of the total liability at these sites, the minimum amount in the range of its estimated probable CERCLA liability, as no amount in the range was considered a better estimate than any other amount.

The timing of payments related to Consumers' remediation and other response activities at its CERCLA and NREPA sites is uncertain. Consumers periodically reviews these cost estimates. A change in the underlying assumptions, such as an increase in the number of sites, different remediation techniques, the nature and extent of contamination, and legal and regulatory requirements, could affect its estimates of NREPA and CERCLA liability.

**Ludington Overhaul Contract Dispute:** Consumers and DTE Electric, co-owners of Ludington, entered into a 2010 engineering, procurement, and construction agreement with Toshiba International, under which Toshiba International contracted to perform a major overhaul and upgrade of Ludington. Toshiba International later assigned the contract and all of its obligations to TAES. TAES' work under the contract was incomplete, defective, and non-conforming. Consumers and DTE Electric repeatedly documented TAES' failure to perform under the contract and demanded that TAES provide a comprehensive plan to resolve those matters, including adherence to its warranty commitments and other contractual obligations. Consumers and DTE Electric engaged in extensive efforts to resolve these issues with TAES, including a formal demand to TAES' parent, Toshiba, under a parent guaranty it provided. TAES did not provide a comprehensive plan or otherwise meet its performance obligations. As a result of TAES' defaults, Consumers and DTE Electric terminated the contract.

In order to enforce their rights under the contract and parent guaranty, and to pursue appropriate damages, Consumers and DTE Electric filed a complaint against TAES and Toshiba in the U.S. District Court for the Eastern District of Michigan in 2022. TAES and Toshiba filed a motion to dismiss the complaint, along with an answer and counterclaims seeking approximately $15 million in damages related to payments allegedly owed under the parties' contract. The court denied the motion to dismiss filed by TAES and Toshiba.

The case against TAES went to trial before a jury and, in December 2025, the jury rendered a verdict in Consumers' and DTE Electric's favor. The jury found that TAES breached the parties' contract and awarded damages of $383 million. The parties separately stipulated to $11 million in additional liquidated damages for late performance by TAES. These amounts are subject to pre- and post-judgment interest. In addition, the jury rejected TAES' counterclaim, determining that Consumers and DTE Electric did not breach the contract. The parent guaranty provided by Toshiba allows Consumers and DTE Electric to recover legal costs in addition to damages. The parties are still engaged in post-verdict proceedings at the District Court and the jury verdict may be appealed; these processes could take two years or more to

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

conclude with finality. The jury verdict was a favorable outcome for Consumers but an unfavorable outcome in these additional proceedings could have a material adverse effect on CMS Energy's and Consumers' financial condition, results of operations, or liquidity. Consumers and DTE Electric must still also resolve their claim against Toshiba under the parent guaranty, which is still pending but which was bifurcated by the Court from the claims against TAES.

Previously, Toshiba announced that TBJH became the majority shareholder and new parent company of Toshiba through a common stock purchase. TBJH is a subsidiary of a Japanese private equity firm. Consumers and DTE Electric do not believe that this affects their rights under the parent guaranty provided by Toshiba.

With MPSC approval, Consumers and DTE Electric were authorized to defer as a regulatory asset the costs associated with repairing or replacing the defective work performed by TAES while the litigation with TAES and Toshiba remains pending. Consumers currently estimates that its share of repair, replacement, and other damages resulting from TAES' defective work is approximately $350 million, which is expected to be offset in part or entirely by future litigation proceeds received from TAES or Toshiba. Consumers and DTE Electric will have the opportunity to seek appropriate recovery and ratemaking treatment for amounts recorded as a regulatory asset following resolution of the litigation, including any amounts not recovered from TAES or Toshiba. Consumers cannot predict the financial impact or outcome of such proceedings.

Consumers Gas Utility Contingencies

Consumers expects to incur remediation and other response activity costs at a number of sites under NREPA. These sites include 23 former MGP facilities. Consumers operated the facilities on these sites for some part of their operating lives. For some of these sites, Consumers has no present ownership interest or may own only a portion of the original site.

At December 31, 2025, Consumers had a recorded liability of $59 million for its remaining obligations for these sites. Consumers expects to pay the following amounts for remediation and other response activity costs in each of the next five years:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| *In Millions* | *In Millions* | *In Millions* | *In Millions* | *In Millions* | *In Millions* |
|  | 2026 | 2027 | 2028 | 2029 | 2030 |
| Remediation and other response activity costs | $3 | $8 | $25 | $11 | $3 |

---

Consumers periodically reviews these cost estimates. Any significant change in the underlying assumptions, such as an increase in the number of sites, changes in remediation techniques, or legal and regulatory requirements, could affect Consumers' estimates of annual response activity costs and the MGP liability.

Pursuant to orders issued by the MPSC, Consumers defers its MGP-related remediation costs and recovers them from its customers over a ten-year period. At December 31, 2025, Consumers had a regulatory asset of $82 million related to the MGP sites.

<sup>1</sup>These obligations arose from the sale of membership interests in Aviator Wind, BG Solar Holdings, Newport Solar Holdings, and NWO Holdco to tax equity investors. NorthStar Clean Energy provided certain indemnity obligations that protect the tax equity investors against losses incurred as a result of breaches of representations and warranties under the associated limited liability company agreements. These obligations are generally capped at an amount equal to the tax equity investor's capital contributions plus a specified return, less any distributions and tax benefits it receives, in connection with its membership interest. For any indemnity obligations related to Aviator Wind, NorthStar Clean Energy would recover 49 percent of any amounts paid to the tax equity investor from the other owner of Aviator Wind Equity Holdings. Additionally, Aviator Wind holds insurance coverage that would partially protect against losses incurred as a result of certain failures to qualify for production tax credits. For further details on NorthStar Clean Energy's ownership interest in these entities, see Note 19, Variable Interest Entities.

<sup>2</sup>These obligations arose from stock and asset sale agreements under which CMS Energy or a subsidiary of CMS Energy indemnified the purchaser for losses resulting from various matters, including claims related to taxes. The maximum obligation amount is mostly related to an Equatorial Guinea tax claim.

<sup>3</sup>This obligation comprises a guarantee provided by Consumers to the DOE in connection with a settlement agreement regarding damages resulting from the department's failure to accept spent nuclear fuel from nuclear power plants formerly owned by Consumers.

Additionally, in the normal course of business, CMS Energy, Consumers, and certain other subsidiaries of CMS Energy have entered into various agreements containing tax and other indemnity provisions for which they are unable to estimate the maximum potential obligation. CMS Energy and Consumers consider the likelihood that they would be required to perform or incur substantial losses related to these indemnities and those disclosed in the table to be remote.

Other Contingencies

In addition to the matters disclosed in this Note and Note 3, Regulatory Matters, there are certain other lawsuits and administrative proceedings before various courts and governmental agencies, as well as unasserted claims that may result in such proceedings, arising in the ordinary course of business to which CMS Energy, Consumers, and certain other subsidiaries of CMS Energy are parties. These other lawsuits, proceedings, and unasserted claims may involve personal injury, property damage, contracts, environmental matters, federal and state taxes, rates, licensing, employment, and other matters. Certain of these matters, while potentially substantial, are covered by insurance and the insurer or insurers are involved in the relevant proceedings. Further, CMS Energy and Consumers occasionally self-report

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

certain regulatory non-compliance matters that may or may not eventually result in administrative proceedings. CMS Energy and Consumers believe that the outcome of any one of these proceedings and potential claims will not have a material negative effect on their consolidated results of operations, financial condition, or liquidity.

Contractual Commitments

**Purchase 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. Related-party PPAs are between Consumers and certain affiliates of NorthStar Clean Energy. Presented in the following table are CMS Energy's and Consumers' contractual purchase obligations at December 31, 2025 for each of the periods shown:

*MCV PPA:* Consumers has a PPA with the MCV Partnership giving Consumers the right to purchase up to 1,240 MW of capacity and energy produced by the MCV Facility through May 2030. The MCV PPA provides for:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a capacity charge of $10.14 per MWh of available capacity through March 2025 and $5.00 per MWh of available capacity from March 2025 through the termination date of the PPA

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a fixed energy charge of $6.30 per MWh for on-peak hours and $6.00 for off-peak hours

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a variable energy charge based on the MCV Partnership's cost of production for energy delivered to Consumers

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a $5 million annual contribution by the MCV Partnership to a renewable resources program through March 2025

Capacity and energy charges under the MCV PPA were $360 million in 2025, $358 million in 2024, and $340 million in 2023.

In September 2025, Consumers entered into a new ten-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. Under the terms of the new agreement, Consumers will pay a monthly capacity charge of $5.00 per MWh of available capacity. Energy payments include a fixed component designed to recover non-fuel operating costs and a variable component based on the MCV Partnership's cost of production for

**Short-term Borrowings:** Under Consumers' commercial paper program, Consumers may issue, in one or more placements, investment-grade commercial paper notes with maturities of up to 365 days at market interest rates. These issuances are supported by Consumers' revolving credit facilities and may have an aggregate principal amount outstanding of up to $500 million. 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.

In December 2025, Consumers renewed a short-term credit agreement with CMS Energy, permitting Consumers to borrow up to $500 million at an interest rate of the prior month's average one-month Term SOFR minus 0.100 percent. At December 31, 2025, outstanding borrowings under the agreement were $340 million bearing interest at 3.859 percent, recorded as current notes payable – related parties on Consumers' consolidated balance sheets.

**NorthStar Clean Energy's Supplier Financing Program:** Under a supplier financing program, NorthStar Clean Energy agrees to pay a bank that is acting as its payment agent the stated amount of confirmed invoices from participating suppliers on the original maturity dates of the invoices. The bank is required to pay the supplier invoices that have been confirmed as valid under the program in full within 135 days of the invoice date. NorthStar Clean Energy does not provide collateral or a guarantee to the bank in support of its payment obligations under the agreement, nor does it pay a fee for the service. NorthStar Clean Energy or the bank may terminate the supplier financing program agreement upon 30 days prior written notice to the other party. Obligations under this program are accounted for in accounts payable on CMS Energy's consolidated balance sheets.

Presented in the following table is the activity under NorthStar Clean Energy's supplier financing program during the year ended December 31, 2025

**Dividend Restrictions:** At December 31, 2025, payment of dividends by CMS Energy on its common stock was limited to $8.9 billion under provisions of the Michigan Business Corporation Act of 1972.

Under the provisions of its articles of incorporation, at December 31, 2025, Consumers had $2.5 billion of unrestricted retained earnings available to pay dividends on its common stock to CMS Energy. Provisions of the Federal Power Act and the Natural Gas Act appear to restrict dividends payable by Consumers to the amount of Consumers' retained earnings. Several decisions from FERC suggest that, under a variety of circumstances, dividends from Consumers on its common stock would not be limited to amounts in Consumers' retained earnings. Any decision by Consumers to pay dividends on its common stock in excess of retained earnings would be based on specific facts and circumstances and would be subject to a formal regulatory filing process.

During the year ended December 31, 2025, Consumers paid $898 million in dividends on its common stock to CMS Energy.

**Capitalization:** The authorized capital stock of CMS Energy consists of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 350 million shares of CMS Energy Common Stock, par value $0.01 per share

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 10 million shares of CMS Energy Preferred Stock, par value $0.01 per share

**Issuance of Common Stock:** 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.

Under the forward sales transactions, CMS Energy may either settle physically by issuing shares of its common stock at the then-applicable forward sale price specified by the agreement or settle net by delivering or receiving cash or shares. CMS Energy may settle the contracts at any time through their maturity dates, and presently intends to physically settle the contracts by delivering shares of its common stock.

As of December 31, 2024, CMS Energy had 0.4 million shares contracted under forward sale agreements at a weighted average initial forward price of $69.43 per share. During the year ended December 31, 2025, CMS Energy entered into forward sale agreements for approximately 6.7 million shares at a weighted average initial forward price of $71.08 per share. During the same period, CMS Energy settled forward sale contracts under this program by issuing approximately 7.0 million shares at a weighted average price of $71.16 per share, resulting in net proceeds of $497 million. Following these transactions, outstanding forward contracts under the program have an aggregate sales price of $8 million, maturing November 30, 2026.

The initial forward price in the forward equity sale contracts includes a deduction for commissions and will be adjusted on a daily basis over the term based on an interest rate factor and decreased on certain dates by certain predetermined amounts to reflect expected dividend payments. No amounts are recorded on CMS Energy's consolidated balance sheets until settlements of the forward equity sale contracts occur. If CMS Energy had elected to net share settle or net cash settle the contracts as of December 31, 2025, it would not have been required to deliver shares or pay cash.

**Preferred Stock:** CMS Energy's Series C preferred stock is traded on the New York Stock Exchange under the symbol CMS PRC. Depositary shares represent a 1/1000th interest in a share of its Series C preferred stock. The Series C preferred stock has no maturity or mandatory redemption date and is not redeemable at the option of the holders. CMS Energy may, at its option, redeem the Series C preferred stock, in whole or in part, at any time on or after July 15, 2026. The Series C preferred stock ranks senior to CMS Energy's common stock with respect to dividend rights and distribution rights upon liquidation. Presented in the following table are details of CMS Energy's Series C preferred stock at December 31, 2025 and 2024:

**6:&nbsp;&nbsp;&nbsp;&nbsp;Fair Value Measurements**

Accounting standards define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. When measuring fair value, CMS Energy and Consumers are required to incorporate all assumptions that market participants would use in pricing an asset or liability, including assumptions about risk. A fair value hierarchy prioritizes inputs used to measure fair value according to their observability in the market. The three levels of the fair value hierarchy are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 inputs are observable, market-based inputs, other than Level 1 prices. Level 2 inputs may include quoted prices for similar assets or liabilities in active markets, quoted prices in inactive markets, and inputs derived from or corroborated by observable market data.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 inputs are unobservable inputs that reflect CMS Energy's or Consumers' own assumptions about how market participants would value their assets and liabilities.

CMS Energy and Consumers classify fair value measurements within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement in its entirety.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Presented in the following table are CMS Energy's and Consumers' assets and liabilities recorded at fair value on a recurring basis:

| &nbsp;&nbsp;&nbsp;Derivative instruments | 3 |  |  |  |
| Total liabilities | $39 | $34 | $27 | $25 |

---

<sup>1</sup>All assets and liabilities were classified as Level 1 with the exception of derivative contracts, which were classified as Level 2 and 3.

**Cash Equivalents:** Cash equivalents and restricted cash equivalents consist of money market funds with daily liquidity.

**Nonqualified Deferred Compensation Plan Assets and Liabilities:** The nonqualified deferred compensation plan assets consist of mutual funds, which are bought and sold only at the discretion of plan participants. The assets are valued using the daily quoted net asset values. CMS Energy and Consumers value their nonqualified deferred compensation plan liabilities based on the fair values of the plan assets, as they reflect the amount owed to the plan participants in accordance with their investment elections. CMS Energy and Consumers report the assets in other non-current assets and the liabilities in other non-current liabilities on their consolidated balance sheets.

**Derivative Instruments:** CMS Energy and Consumers value their derivative instruments using either a market approach that incorporates information from market transactions, or an income approach that discounts future expected cash flows to a present value amount. CMS Energy's and Consumers' derivatives are classified as Level 2 and 3.

The derivatives classified as Level 2 are interest rate swaps at NorthStar Clean Energy, which are valued using market-based inputs.

In February 2025, a subsidiary of NorthStar Clean Energy entered into floating-to-fixed interest rate swaps to reduce the impact of interest rate fluctuations associated with interest payments on certain future long-term variable-rate debt. The interest rate swaps economically hedge the future variability of interest payments on debt with a notional amount of $109 million. Gains or losses on these swaps are reported in other expense on CMS Energy's consolidated statements of income. The amount recorded in other expense was $3 million for the year ended December 31, 2025. The fair value of these swaps recorded in

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

other non-current liabilities on CMS Energy's consolidated balance sheets totaled $3 million at December 31, 2025.

The majority of derivatives classified as Level 3 are FTRs held by Consumers. Due to the lack of quoted pricing information, Consumers determines the fair value of its FTRs based on Consumers' average historical settlements. Consumers reports derivatives associated with FTRs in other current assets on its consolidated balance sheets.There was no material activity within the Level 3 category of derivatives during the periods presented.

**7:&nbsp;&nbsp;&nbsp;&nbsp;Financial Instruments**

Presented in the following table are the carrying amounts and fair values, by level within the fair value hierarchy, of CMS Energy's and Consumers' financial instruments that are not recorded at fair value. The table excludes cash, cash equivalents, short-term financial instruments, and trade accounts receivable and payable whose carrying amounts approximate their fair values. For information about assets and liabilities recorded at fair value and for additional details regarding the fair value hierarchy, see Note 6, Fair Value Measurements.

Consumers' intangible asset retirements were $64 million for the year ended December 31, 2025 and $153 million for the year ended December 31, 2024.

<sup>2</sup>Leasehold improvements are amortized over the life of the lease, which may change whenever the lease is renewed or extended.

**Capitalization:** CMS Energy and Consumers record plant, property, and equipment at original cost when placed into service. The cost includes labor, material, applicable taxes, overhead such as pension and other benefits, and AFUDC, if applicable. Consumers' plant, property, and equipment is generally recoverable through its general ratemaking process.

With the exception of utility property for which the remaining book value has been securitized, mothballed utility property stays in rate base and continues to be depreciated at the same rate as before the mothball period. When utility property is retired or otherwise disposed of in the ordinary course of business, Consumers records the original cost to accumulated depreciation, along with associated cost of removal, net of salvage. CMS Energy and Consumers recognize gains or losses on the retirement or disposal of non-regulated assets in income. Consumers records cost of removal collected from customers, but not spent, as a regulatory liability.

*Software:* CMS Energy and Consumers capitalize the costs to purchase and develop internal-use computer software. These costs are expensed evenly over the estimated useful life of the internal-use computer software. If computer software is integral to computer hardware, then its cost is capitalized and depreciated with the hardware.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

*AFUDC:* Consumers capitalizes AFUDC on regulated major construction projects. AFUDC represents the estimated cost of debt and authorized return-on-equity funds used to finance construction additions. Consumers records the offsetting credit as a reduction of interest for the amount representing the borrowed funds component and as other income for the equity funds component on the consolidated statements of income. When construction is completed and the property is placed in service, Consumers depreciates and recovers the capitalized AFUDC from customers over the life of the related asset. Presented in the following table are Consumers' average AFUDC capitalization rates:

Consumers is required to provide only its share of financing for the jointly owned utility facilities.

Consumers plans to retire J.H. Campbell and, in 2022, removed an amount representing the projected remaining book value of the electric generating units upon their retirement from total plant, property, and equipment and recorded it as a regulatory asset on its consolidated balance sheets. The retirement of J.H. Campbell is subject to temporary extensions under emergency orders issued by the U.S. Secretary of Energy. For additional details, see Note 3, Regulatory Matters.

Consumers and DTE Electric engaged in litigation with TAES and Toshiba related to TAES' incomplete, defective, and nonconforming work during a major overhaul and upgrade of Ludington. For additional details on this dispute, see Note 4, Contingencies and Commitments—Ludington Overhaul Contract Dispute.

**9:&nbsp;&nbsp;&nbsp;&nbsp;Leases**

Lessee

CMS Energy and Consumers lease various assets from third parties, including coal-carrying railcars, real estate, service vehicles, and gas pipeline capacity. In addition, CMS Energy and Consumers account for several of their PPAs as leases.

CMS Energy and Consumers do not record right-of-use assets or lease liabilities on their consolidated balance sheets for rentals with lease terms of 12 months or less, most of which are for the lease of real estate and service vehicles. Lease expense for these rentals is recognized on a straight-line basis over the lease term.

CMS Energy and Consumers include future payments for all renewal options, fair market value extensions, and buyout provisions reasonably certain of exercise in their measurement of lease right-of-use assets and lease liabilities. In addition, certain leases for service vehicles contain end-of-lease adjustment clauses based on proceeds received from the sale or disposition of the vehicles. CMS Energy and Consumers also include executory costs in the measurement of their right-of-use assets and lease liabilities, except for maintenance costs related to their coal-carrying railcar leases.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

Most of Consumers' PPAs contain provisions at the end of the initial contract terms to renew the agreements annually under mutually agreed-upon terms at the time of renewal. Energy and capacity payments that vary depending on quantities delivered are recognized as variable lease costs when incurred. Consumers accounts for a PPA with one of CMS Energy's equity method subsidiaries as a finance lease.

Lessor

CMS Energy and Consumers are the lessor under power sales and natural gas delivery agreements that are accounted for as leases.

CMS Energy has power sales agreements that are accounted for as operating leases. In addition to fixed payments, these agreements have variable payments based on energy delivered. For the year ended December 31, 2025, lease revenue from these power sales agreements was $149 million, which included variable lease payments of $105 million. For the year ended December 31, 2024, lease revenue from these power sales agreements was $105 million, which included variable lease payments of $61 million. These non-cancelable operating leases expire in 2026; remaining minimum rental payments amount to $18 million.

Consumers has a natural gas transportation agreement with a subsidiary of CMS Energy that extends through 2038, related to a pipeline owned by Consumers. This agreement is accounted for as a direct finance lease and will automatically extend annually unless terminated by either party. The effects of the lease are eliminated on CMS Energy's consolidated financial statements.

Minimum rental payments to be received under Consumers' direct financing lease are $1 million for each of the next five years and $6 million for the years thereafter. The lease receivable was $5 million as of December 31, 2025, which does not include unearned income of $5 million.

**10:&nbsp;&nbsp;&nbsp;&nbsp;Asset Retirement Obligations**

CMS Energy and Consumers record the fair value of the cost to remove assets at the end of their useful lives, if there is a legal obligation to remove them. If a reasonable estimate of fair value cannot be made in the period in which the ARO is incurred, such as for assets with indeterminate lives, the liability is recognized when a reasonable estimate of fair value can be made. CMS Energy and Consumers have not recorded liabilities associated with the closure of their hydroelectric facilities and certain gas wells that have an indeterminate life or for assets that have immaterial cumulative disposal costs, such as substation batteries.

CMS Energy and Consumers calculate the fair value of ARO liabilities using an expected present-value technique that reflects assumptions about costs and inflation, and uses a credit-adjusted risk-free rate to discount the expected cash flows. CMS Energy's ARO liabilities are primarily at Consumers.

Presented below are the categories of assets that CMS Energy and Consumers have legal obligations to remove at the end of their useful lives and for which they have an ARO liability recorded:

---

| | |
|:---|:---|
| ARO Description | Long-lived Assets |
| Closure of coal ash disposal areas | Generating plants coal ash areas |
| Gas distribution cut, purge, and cap | Gas distribution mains and services |
| Asbestos abatement | Electric and gas utility plant |
| Closure of renewable generation assets | Wind and solar generation facilities |
| Capping and partial filling of water intake line | Generating plant water intake line |
| Gas wells plug and abandon | Gas transmission and storage |

---

In May 2024, the EPA finalized a rule regulating CCR impoundments at electric generating facilities that became inactive prior to the effective date of a rule published in 2015 regulating CCRs under RCRA. 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.

In response to the new rule, Consumers has been performing its review of legacy impoundments and of other aspects of the 2024 rule in accordance with the timelines prescribed by the rule, including the requirement to determine and report the presence of any CCR management units to the EPA by February 2027. Consumers has been recording incremental AROs for legacy impoundments and CCR management units when a reasonable estimate of the fair value of the associated costs can be made, and the ultimate amount of any resulting ARO could be material. 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. Consumers has historically been authorized to recover in electric rates costs related to coal ash disposal sites.

<sup>1&nbsp;&nbsp;&nbsp;&nbsp;</sup>The increase in the AROs associated with coal ash disposal areas was primarily the result of incremental remedies required by EGLE for certain ash disposal ponds and incremental AROs recorded in response to reviews of legacy CCR impoundments.

<sup>2</sup>&nbsp;&nbsp;&nbsp;&nbsp;The increase in AROs associated with water intake lines, which were previously immaterial, was primarily the result of changes in the expected scope of required capping following the finalization of decommissioning plans with the local jurisdiction.

**11:&nbsp;&nbsp;&nbsp;&nbsp;Retirement Benefits**

**Benefit Plans:** CMS Energy and Consumers provide pension, OPEB, and other retirement benefits to eligible employees under a number of different plans. These plans include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• non-contributory, qualified DB Pension Plans (closed to new non-union participants as of July 1, 2003 and closed to new union participants as of September 1, 2005)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a non-contributory, qualified DCCP for employees hired on or after July 1, 2003

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• benefits to certain management employees under a non-contributory, nonqualified DB SERP (closed to new participants as of March 31, 2006)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a non-contributory, nonqualified DC SERP for certain management employees hired or promoted on or after April 1, 2006

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a contributory, qualified defined contribution 401(k) plan

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• health care and life insurance benefits under an OPEB Plan

*DB Pension Plans:* Participants in the pension plans include present and former employees of CMS Energy and Consumers, including certain present and former affiliates and subsidiaries. Pension plan trust assets are not distinguishable by company. Effective December 31, 2017, CMS Energy's and Consumers' then-existing pension plan was amended to include only retired and former employees already covered; this amended plan is referred to as DB Pension Plan B. Also effective December 31, 2017, active employees were moved to a newly created pension plan, referred to as DB Pension Plan A, whose benefits mirror those provided under DB Pension Plan B. Maintaining separate plans for the two groups allows CMS Energy and Consumers to employ a more targeted investment strategy and provides additional opportunities to mitigate risk and volatility.

*DCCP:* CMS Energy and Consumers provide an employer contribution to the DCCP 401(k) plan for employees hired on or after July 1, 2003. The contribution ranges from 5 percent to 10 percent of base pay, depending on years of service and employee class. Employees are not required to contribute in order to receive the plan's employer contribution. DCCP expense for CMS Energy, including Consumers, was $57 million for the year ended December 31, 2025, $53 million for the year ended December 31, 2024, and $51 million for the year ended December 31, 2023. DCCP expense for Consumers was $55 million for the year ended December 31, 2025, $52 million for the year ended December 31, 2024, and $50 million for the year ended December 31, 2023.

*DB SERP:* The DB SERP is a nonqualified plan as defined by the Internal Revenue Code. DB SERP benefits are paid from a rabbi trust. The trust assets are not considered plan assets under ASC 715. DB SERP rabbi trust earnings are taxable. Presented in the following table are the fair values of trust assets and ABO for CMS Energy's and Consumers' DB SERP:

---

| | | |
|:---|:---|:---|
| *In Millions* | *In Millions* | *In Millions* |
| Years Ended December 31 | 2025 | 2024 |
| **CMS Energy, including Consumers** |  |  |

| ABO | 104 | 105 |
| **Consumers** |  |  |
| Trust assets | $92 | $95 |
| ABO | 76 | 76 |

---

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

Neither CMS Energy nor Consumers made any contributions to the DB SERP in 2025 or 2024.

*DC SERP:* On April 1, 2006, CMS Energy and Consumers implemented a DC SERP and froze further new participation in the DB SERP. The DC SERP provides participants benefits ranging from 5 percent to 15 percent of total compensation. The DC SERP requires a minimum of five years of participation before vesting. CMS Energy's and Consumers' contributions to the plan, if any, are placed in a grantor trust. For CMS Energy and Consumers, trust assets were $18 million at December 31, 2025 and $17 million at December 31, 2024. DC SERP assets are included in other non-current assets on CMS Energy's and Consumers' consolidated balance sheets. CMS Energy's and Consumers' DC SERP expense was $1 million for the years ended December 31, 2025, 2024, and 2023.

*401(k) Plan:* The 401(k) plan employer match equals 4 to 6 percent of employee eligible contributions based on an employee's wages and class. The total 401(k) plan cost for CMS Energy, including Consumers, was $46 million for the year ended December 31, 2025, and $41 million for the years ended December 31, 2024 and 2023. The total 401(k) plan cost for Consumers was $44 million for the year ended December 31, 2025, $39 million for the year ended December 31, 2024, and $40 million for the year ended December 31, 2023.

*Health-related OPEB Plan:* Participants in the health-related OPEB Plan include regular full-time employees covered by the employee health care plan on the day before retirement from either CMS Energy or Consumers at age 55 or older with at least ten full years of applicable continuous service and hired before January 1, 2007 for non-union participants and hired before September 1, 2010 for union participants. Regular full-time employees who qualify for disability retirement under the DB Pension Plans or are disabled and covered by the DCCP and who have 15 years of applicable continuous service may also participate in the health-related OPEB Plan if hired before January 1, 2007 for non-union participants and hired before September 1, 2010 for union participants. Retiree health care costs were based on the assumption that costs would increase 8.00 percent in 2026 and 8.50 percent in 2025 for those under 65 and would increase 9.75 percent in 2026 and 10.25 percent in 2025 for those over 65. The rate of increase was assumed to decline to 4.75 percent by 2034 and thereafter for all retirees.

<sup>1</sup>The mortality assumption for benefit obligations and net periodic benefit cost was based on the Pri-2012 Mortality Table, with improvement scale MP-2021.

<sup>2</sup>The discount rate reflects the rate at which benefits could be effectively settled and is equal to the equivalent single rate resulting from a yield-curve analysis. This analysis incorporated the projected benefit payments specific to CMS Energy's and Consumers' DB Pension Plans and OPEB Plan and the yields on high-quality corporate bonds rated Aa or better.

<sup>3</sup>CMS Energy and Consumers have elected to use a full-yield-curve approach in the estimation of service cost and interest cost; this approach applies individual spot rates along the yield curve to future projected benefit payments based on the time of payment.

<sup>4</sup>The last active participant in the DB SERP retired in 2023. Thus, the determination of the associated net periodic benefit cost no longer assumes a service cost discount rate nor a rate of compensation increase.

<sup>5</sup>CMS Energy and Consumers determined the long-term rate of return using historical market returns, the present and expected future economic environment, the capital market principles of risk and return, and the expert opinions of individuals and firms with financial market knowledge. CMS Energy and Consumers considered the asset allocation of the portfolio in forecasting the future expected total return of the portfolio. The goal was to determine a long-term rate of return that could be incorporated into the planning

of future cash flow requirements in conjunction with the change in the liability. Annually, CMS Energy and Consumers review for reasonableness and appropriateness the forecasted returns for various classes of assets used to construct an expected return model. CMS Energy's and Consumers' expected long-term rate of return on the assets of the DB Pension Plans was 7.30 percent in 2025. The actual return on the assets of the DB Pension Plans was 12.7 percent in 2025, 3.6 percent in 2024, and 12.6 percent in 2023.

**Costs:** Presented in the following table are the costs (credits) and other changes in plan assets and benefit obligations incurred in CMS Energy's and Consumers' retirement benefit plans:

In Consumers' electric and gas rate cases, the MPSC approved a mechanism allowing Consumers to defer for future recovery or refund pension and OPEB expenses above or below the amounts used to set existing rates. Amounts deferred will be collected from or refunded to customers over ten years. At December 31, 2025, CMS Energy, including Consumers, had deferred $3 million of pension costs and $6 million of OPEB credits under this mechanism related to 2025 expense. At December 31, 2024, CMS Energy, including Consumers, had deferred $15 million of pension credits and $11 million of OPEB credits under this mechanism related to 2024 expense. At December 31, 2023, CMS Energy, including Consumers, had deferred $11 million of pension credits and $23 million of OPEB costs under this mechanism related to 2023 expense.

CMS Energy and Consumers amortize net gains and losses in excess of 10 percent of the greater of the PBO or the MRV over the average remaining service period for DB Pension Plan A and the OPEB Plan and over the average remaining life expectancy of participants for DB Pension Plan B. For DB Pension Plan A, the estimated period of amortization of gains and losses was seven years for the year ended December 31, 2025, and eight years for the years ended December 31, 2024 and 2023. For DB Pension Plan B, the estimated period of amortization of gains and losses was 17 years for the years ended

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

December 31, 2025, 2024, and 2023. For the OPEB Plan, the estimated amortization period was nine years for the years ended December 31, 2025, 2024, and 2023.

Prior service cost (credit) amortization is established in the year in which the prior service cost (credit) first occurred, and is based on the same amortization period for all future years until the prior service cost (credit) is fully amortized. CMS Energy and Consumers had new prior service costs for OPEB in 2024. The estimated period of amortization of these new prior service costs is seven years.

CMS Energy and Consumers determine the MRV for the assets of the DB Pension Plans as the fair value of plan assets on the measurement date, adjusted by the gains or losses that will not be admitted into the MRV until future years. CMS Energy and Consumers reflect each year's gain or loss in the MRV in equal amounts over a five-year period beginning on the date the original amount was determined. CMS Energy and Consumers determine the MRV for OPEB Plan assets as the fair value of assets on the measurement date.

*Cash and Short-term Investments:* Cash and short-term investments consist of money market funds with daily liquidity.

*U.S. Government and Agencies Securities:* U.S. government and agencies securities consist of U.S. Treasury notes and other debt securities backed by the U.S. government and related agencies. These securities are valued based on quoted market prices.

*Corporate Debt:* Corporate debt investments consist of investment grade bonds of U.S. issuers from diverse industries. These securities are valued based on quoted market prices, when available, or yields available on comparable securities of issuers with similar credit ratings.

*State and Municipal Bonds:* State and municipal bonds are valued using a matrix-pricing model that incorporates Level 2 market-based information. The fair value of the bonds is derived from various observable inputs, including benchmark yields, reported securities trades, broker/dealer quotes, bond ratings, and general information on market movements for investment grade state and municipal securities normally considered by market participants when pricing such debt securities.

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

*Foreign Bonds:* Foreign corporate and government debt securities are valued based on quoted market prices, when available, or on yields available on comparable securities of issuers with similar credit ratings.

*Common Stocks:* Common stocks in the OPEB Plan consist of equity securities that are actively managed and tracked to the S&P 500 Index and MSCI All Country World ex-US. These securities are valued at their quoted closing prices.

*Mutual Funds:* Mutual funds represent shares in registered investment companies that are priced based on the daily quoted net asset values that are publicly available and are the basis for transactions to buy or sell shares in the funds.

*Pooled Funds:* Pooled funds include both common and collective trust funds as well as special funds that contain only employee benefit plan assets from two or more unrelated benefit plans. These funds primarily consist of U.S. and foreign equity securities, but also include U.S. and foreign fixed-income securities and multi-asset investments. Since these investments are valued at their net asset value as a practical expedient, they are not classified in the fair value hierarchy.

*Asset Allocations:* Presented in the following table are the investment components of the assets of CMS Energy's DB Pension Plans and OPEB Plan as of December 31, 2025:

---

| | | |
|:---|:---|:---|
| | DB Pension Plans | OPEB Plan |
| Fixed-income securities | 39.2% | 37.6% |
| Equity securities | 38.7 | 42.4 |
| Real asset investments | 9.3 | 8.8 |
| Return-seeking fixed income | 7.1 | 5.6 |
| Liquid alternative investments | 4.3 | 3.7 |
| Cash and cash equivalents | 1.4 | 1.9 |
|  | 100.0% | 100.0% |

---

CMS Energy's target 2025 asset allocation for the assets of the DB Pension Plans was 40-percent fixed income, 38-percent equity, 11-percent real assets, 7-percent return-seeking fixed income, and 4-percent liquid alternatives.

CMS Energy established union and non-union VEBA trusts to fund future retiree health and life insurance benefits known as OPEB. These trusts are funded through the ratemaking process for Consumers and through direct contributions from the non-utility subsidiaries. CMS Energy's target 2025 asset allocation for OPEB trusts was 40-percent fixed income, 38-percent equity, 11-percent real assets, 7-percent return-seeking fixed income, and 4-percent liquid alternatives.

The goal of these target allocations was to maximize the long-term return on plan assets, while maintaining a prudent level of risk. The level of acceptable risk is a function of the liabilities of the plans. Equity investments are diversified mostly across the S&P 500 Index, with lesser allocations to the S&P MidCap and SmallCap Indexes and Foreign Equity Funds. Fixed-income investments are diversified across investment grade instruments of government and corporate issuers, as well as high-yield and global bond funds. Return-seeking fixed-income investments are diversified exposure to high-yield bonds, emerging market debt, and bank loans. Real asset investments are diversified across core real estate and real estate investment trusts. Liquid alternatives are investments in private funds comprised of different and independent hedge funds with various investment strategies. CMS Energy uses annual liability measurements, quarterly portfolio reviews, and periodic asset/liability studies to evaluate the need for adjustments to the portfolio allocations.

**Contributions:** Contributions comprise required amounts and discretionary contributions. Neither CMS Energy nor Consumers made any contributions in 2025 or 2024, or plans to contribute to the DB Pension Plans or OPEB Plan in 2026. Actual future 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.

**Benefit Payments:** Presented in the following table are the expected benefit payments for each of the next five years and the five-year period thereafter:

**12:&nbsp;&nbsp;&nbsp;&nbsp;Stock-based Compensation**

CMS Energy and Consumers provide a PISP to officers, employees, and non-employee directors based on their contributions to the successful management of the company. The PISP has a ten-year term, expiring in May 2030.

In 2025, all awards were in the form of restricted stock or restricted stock units. The PISP also allows for unrestricted common stock, stock options, stock appreciation rights, phantom shares, performance units, and incentive options, none of which was granted in 2025, 2024, or 2023.

Shares awarded or subject to stock options, phantom shares, or performance units may not exceed 6.5 million shares from June 2020 through May 2030. CMS Energy and Consumers may issue awards of up to 3,965,601 shares of common stock under the PISP as of December 31, 2025. Shares for which payment or exercise is in cash, as well as shares that expire, terminate, or are canceled or forfeited, may be awarded or granted again under the PISP.

All awards under the PISP vest fully upon death. Upon a change of control of CMS Energy or termination under an officer separation agreement, the awards will vest in accordance with specific officer agreements. If stated in the award, for restricted stock recipients who terminate employment due to retirement or disability, a pro-rata portion of the award will vest upon termination, with any market-based award also contingent upon the outcome of the market condition and any performance-based award contingent upon the outcome of the performance condition. The pro-rata portion is equal to the portion of the service period served between the award grant date and the employee's termination date. The remaining portion of the awards will be forfeited. All awards for directors vest fully upon retirement. Restricted shares may be forfeited if employment terminates for any other reason or if the minimum service requirements are not met, as described in the award document.

**Restricted Stock Awards:** Restricted stock awards for employees under the PISP are in the form of performance-based, market-based, and time-lapse restricted stock. Award recipients receive shares of CMS Energy common stock that have dividend and voting rights. The dividends on time-lapse restricted stock are paid in cash or in CMS Energy common stock. The dividends on performance-based and market-based restricted stock are paid in restricted shares equal to the value of the dividends. These additional restricted shares are subject to the same vesting conditions as the underlying restricted stock shares.

Performance-based restricted stock vesting is contingent on meeting at least a 36-month service requirement and a performance condition. The performance condition is based on an adjusted measure of CMS Energy's EPS growth relative to a peer group over a three-year period. The awards granted in 2025, 2024, and 2023 require a 38-month service period. Market-based restricted stock vesting is generally contingent on meeting a three-year service requirement and a market condition. The market condition is based on a comparison of CMS Energy's total shareholder return with the median total shareholder return of a peer group over the same three-year period. Depending on the outcome of the performance condition or the market condition, a recipient may earn a total award ranging from zero to 200 percent of the initial grant. Time-lapse restricted stock generally vests after a service period of three years.

**Restricted Stock Units:** In 2025, 2024, and 2023, CMS Energy and Consumers granted restricted stock units to certain non-employee directors who elected to defer their restricted stock awards. The restricted stock units generally vest after a service period of one year or, if earlier, at the next annual meeting. The restricted stock units will be distributed to the recipients as shares in accordance with the directors' deferral agreements. Restricted stock units do not have voting rights, but do have dividend rights. In lieu of cash dividend payments, the dividends on restricted stock units are paid in additional units equal to the value of the dividends. These additional restricted stock units are subject to the same vesting and

distribution conditions as the underlying restricted stock units. No restricted stock units were forfeited during 2025.

Presented in the following tables is the activity for restricted stock and restricted stock units under the PISP:

CMS Energy and Consumers charge the fair value of the restricted stock awards to expense over the required service period and charge the fair value of the restricted stock units to expense immediately. For performance-based awards, CMS Energy and Consumers estimate the number of shares expected to vest at the end of the performance period based on the probable achievement of the performance objective. Performance-based and market-based restricted stock awards have graded vesting features for retirement-eligible employees, and CMS Energy and Consumers recognize expense for those awards on a graded vesting schedule over the required service period. Expense for performance-based and market-based restricted stock awards for non-retirement-eligible employees and time-lapse awards is recognized on a straight-line basis over the required service period.

The fair value of performance-based and time-lapse restricted stock and restricted stock units is based on the price of CMS Energy's common stock on the grant date. The fair value of market-based restricted stock awards is calculated on the grant date using a Monte Carlo simulation. CMS Energy and Consumers

base expected volatilities on the historical volatility of the price of CMS Energy common stock. The risk-free rate for valuation of the market-based restricted stock awards was based on the three-year U.S. Treasury yield at the award grant date.

Presented in the following table are the most significant assumptions used to estimate the fair value of the market-based restricted stock awards:

At December 31, 2025, $28 million of total unrecognized compensation cost was related to restricted stock for CMS Energy, including Consumers, and $26 million of total unrecognized compensation cost was related to restricted stock for Consumers. CMS Energy and Consumers expect to recognize this cost over a weighted-average period of two years.

**13:&nbsp;&nbsp;&nbsp;&nbsp;Income Taxes**

CMS Energy and its subsidiaries file a consolidated U.S. federal income tax return as well as a Michigan Corporate Income Tax return for the unitary business group and various other state unitary group combined income tax returns. Income taxes are allocated based on each company's separate taxable income in accordance with the CMS Energy tax sharing agreement.

<sup>1</sup>In June 2025, state deferred tax balances were increased by $12 million to reflect a change in Illinois tax policy that establishes nexus for Consumers. The policy change is effective for tax years beginning January 1, 2026. During 2023, CMS Energy initiated a plan to divest immaterial business activities in a non-Michigan jurisdiction and will no longer have a taxable presence within that jurisdiction. As a result of these actions, CMS Energy reversed a $13 million non-Michigan reserve, all of which was recognized at Consumers.

<sup>2</sup>During 2024, Consumers recognized a $16 million tax benefit resulting from the expiration of the statute of limitations associated with audit points for the 2018 and 2019 tax years.

**State Income Tax Claim:** In February 2025, CMS Energy received an adverse ruling from the Michigan Tax Tribunal in regards to the methodology of state apportionment for Consumers' electricity sales to MISO. In March 2025, CMS Energy filed an appeal with the Michigan Court of Appeals and a hearing was held in February 2026. CMS Energy and Consumers have evaluated and concluded their uncertain tax positions associated with this matter to be sufficient as of December 31, 2025. While CMS Energy and Consumers expect the appeal to prevail, if it were to fail, the companies would be required to revise the estimated value of their state deferred tax liabilities, which could result in a material impact to their results of operations.

**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

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

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.

**Renewable Energy Tax Credits:** Under the Inflation Reduction Act of 2022, renewable energy tax credits produced after 2022 are eligible to be transferred to third parties. These sales are accounted for under ASC 740 with the discount from the sale of the tax credits included as a component of income tax expense. Renewable energy tax credits that have been generated and sold are presented as accounts receivable on CMS Energy's and Consumers' consolidated balance sheets until proceeds from the sale are received. Proceeds from the sale of tax credits are presented as operating activities on their consolidated statements of cash flows, consistent with the presentation of cash taxes paid.

During 2025, CMS Energy sold renewable energy tax credits generated in 2025 and received proceeds of $36 million, all of which was recognized at Consumers. CMS Energy also received proceeds of $13 million during 2025 from the 2024 sale of renewable energy tax credits, all of which was recognized at Consumers. CMS Energy will receive an additional $32 million in 2026 from the renewable energy tax credits generated and sold in 2025, of which $10 million will be recognized at Consumers.

| Total tax attributes | $18 |  |

---

<sup>1</sup>General business credits comprise research and development tax credits and renewable energy tax credits that are not expected to be transferred to third parties.

CMS Energy has provided a valuation allowance of $2 million for state and local tax loss carryforwards. CMS Energy and Consumers expect to utilize fully their tax loss and credit carryforwards for which no valuation allowance has been provided. It is reasonably possible that further adjustments will be made to the valuation allowances within one year.

---

If recognized, all of these uncertain tax benefits would affect CMS Energy's and Consumers' annual effective tax rates in future years. One uncertain tax benefit relates to the methodology of state apportionment for Consumers' electricity sales to MISO. CMS Energy has filed an appeal on an adverse ruling received from the Michigan Tax Tribunal on this methodology and a hearing was held in February 2026.

CMS Energy and Consumers recognize accrued interest and penalties, where applicable, as part of income tax expense. CMS Energy, including Consumers, recognized immaterial interest and penalties for each of the years ended December 31, 2025, 2024, and 2023.

The amount of income taxes paid is subject to ongoing audits by federal, state, local, and foreign tax authorities, which can result in proposed assessments. CMS Energy's federal income tax returns for 2022 and subsequent years remain subject to examination by the IRS. CMS Energy's Michigan Corporate Income Tax returns for 2013 through 2016 and 2021 and subsequent years remain subject to examination by the State of Michigan. CMS Energy's and Consumers' estimate of the potential outcome for any uncertain tax issue is highly judgmental. CMS Energy and Consumers believe that their accrued tax liabilities at December 31, 2025 were adequate for all years.

**14:&nbsp;&nbsp;&nbsp;&nbsp;Earnings Per Share—CMS Energy**

Nonvested Stock Awards

CMS Energy's nonvested stock awards are composed of participating and non-participating securities. The participating securities accrue cash dividends when common stockholders receive dividends. Since the recipient is not required to return the dividends to CMS Energy if the recipient forfeits the award, the nonvested stock awards are considered participating securities. As such, the participating nonvested stock awards were included in the computation of basic EPS. The non-participating securities accrue stock dividends that vest concurrently with the stock award. If the recipient forfeits the award, the stock dividends accrued on the non-participating securities are also forfeited. Accordingly, the non-participating awards and stock dividends were included in the computation of diluted EPS, but not in the computation of basic EPS.

Forward Equity Sale Contracts

CMS Energy has entered into forward equity sale contracts. These forward equity sale contracts are non-participating securities. While the forward sale price in the forward equity sale contract is decreased on certain dates by certain predetermined amounts to reflect expected dividend payments, these price adjustments were set upon inception of the agreement and the forward contract does not give the owner the right to participate in undistributed earnings. Accordingly, the forward equity sale contracts were included in the computation of diluted EPS, but not in the computation of basic EPS.

The potentially dilutive impact from these forward equity sale contracts is reflected in diluted EPS using the treasury stock method. There will be a dilutive effect on EPS when the average market price of common stock shares is above the applicable adjusted forward sale price. Additionally, any physical settlement or net share settlement of the agreements would dilute EPS. For further details on the forward equity sale contracts, see Note 5, Financings and Capitalization.

Convertible Securities

CMS Energy has issued convertible senior notes. Potentially dilutive common shares issuable upon conversion of the convertible senior notes are determined using the if-converted method for calculating diluted EPS. Upon conversion, the convertible senior notes are required to be paid in cash with only amounts exceeding the principal permitted to be settled in shares. Accordingly, the convertible senior notes were included in the computation of diluted EPS, but not in the computation of basic EPS. The impact to diluted EPS was de minimis.

Electric and Gas Utilities

**Consumers Utility Revenue:** Consumers recognizes revenue primarily from the sale of electric and gas utility services at tariff-based rates regulated by the MPSC. Consumers' customer base consists of a mix of residential, commercial, and diversified industrial customers. Consumers' tariff-based sales performance obligations are described below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Consumers has performance obligations for the service of standing ready to deliver electricity or natural gas to customers, and it satisfies these performance obligations over time. Consumers recognizes revenue at a fixed rate as it provides these services. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by the MPSC through the rate-making process and represent the stand-alone selling price of Consumers' service to stand ready to deliver.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Consumers has performance obligations for the service of delivering the commodity of electricity or natural gas to customers, and it satisfies these performance obligations upon delivery. Consumers recognizes revenue at a price per unit of electricity or natural gas delivered, based on the tariffs established by the MPSC. These arrangements generally do not have fixed terms and remain in effect as long as the customer consumes the utility service. The rates are set by the MPSC through the rate-making process and represent the stand-alone selling price of a bundled product comprising the commodity, electricity or natural gas, and the service of delivering such commodity.

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

In some instances, Consumers has specific fixed-term contracts with large commercial and industrial customers to provide electricity or gas at certain tariff rates or to provide gas transportation services at contracted rates. The amount of electricity and gas to be delivered under these contracts and the associated future revenue to be received are generally dependent on the customers' needs. Accordingly, Consumers recognizes revenues at the tariff or contracted rate as electricity or gas is delivered to the customer. Consumers also has other miscellaneous contracts with customers related to pole and other property rentals and utility contract work. Generally, these contracts are short term or evergreen in nature.

**Accounts Receivable and Unbilled Revenues:** Accounts receivable comprise trade receivables and unbilled receivables. CMS Energy and Consumers record their accounts receivable at cost less an allowance for uncollectible accounts. The allowance is increased for uncollectible accounts expense and decreased for account write-offs net of recoveries. CMS Energy and Consumers establish the allowance based on historical losses, management's assessment of existing economic conditions, customer payment trends, and reasonable and supported forecast information. CMS Energy and Consumers assess late payment fees on trade receivables based on contractual past-due terms established with customers. Accounts are written off when deemed uncollectible, which is generally when they become six months past due.

CMS Energy and Consumers recorded uncollectible accounts expense of $40 million for the year ended December 31, 2025, $33 million for the year ended December 31, 2024, and $34 million for the year ended December 31, 2023.

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. Unbilled revenues, which are recorded as accounts receivable and accrued revenue on CMS Energy's and Consumers' consolidated balance sheets, were $659 million at December 31, 2025 and $584 million at December 31, 2024.

**Alternative**-**revenue Programs:** Consumers accounts for its energy waste reduction incentive mechanism, financial compensation mechanism, and demand response incentive mechanism as alternative-revenue programs.

Consumers recognizes revenue related to the energy waste reduction incentive as soon as energy savings exceed the annual targets established by the MPSC. Revenue related to the financial compensation mechanism is recognized as payments are made on MPSC-approved PPAs. Under a demand response incentive mechanism, Consumers earns a financial incentive when it meets demand response targets set by the MPSC. Consumers recognizes revenue related to this program once demand response incentive objectives are complete, the incentive amount is calculable, and the incentive revenue will be collected within a 24-month period. For additional information on these mechanisms, see Note 3, Regulatory Matters.

Consumers does not reclassify revenue from its alternative-revenue program to revenue from contracts with customers at the time the amounts are collected from customers.

**17:&nbsp;&nbsp;&nbsp;&nbsp;Reportable Segments**

Reportable segments consist of business units defined by the products and services they offer. CMS Energy's and Consumers' chief operating decision-maker is the CEO. The chief operating decision-maker evaluates segment performance and profitability using net income available to CMS Energy's common stockholders. This metric provides a clear, consistent basis for analyzing the financial results of each segment and supports decision-making regarding the allocation of resources.

Resource allocation to CMS Energy's and Consumers' segments begins with the annual budgeting process, which establishes initial funding and resource levels for each segment. The budget incorporates key financial and operational inputs, including anticipated revenues, expenses, and capital requirements, aligning with CMS Energy's and Consumers' strategic objectives and regulatory obligations. The chief operating decision-maker reviews budget-to-actual variances on a monthly basis and makes interim decisions to reallocate resources among segments as needed, ensuring a timely and effective response to changing conditions. For the electric utility and gas utility segments, the chief operating decision-maker uses this assessment to determine whether the segments are achieving their regulatory authorized return on equity.

Accounting policies for CMS Energy's and Consumers' segments are as described in Note 1, Significant Accounting Policies. The consolidated financial statements reflect the assets, liabilities, revenues, and expenses of the individual segments when appropriate. Accounts are allocated among the segments when common accounts are attributable to more than one segment. The allocations are based on certain measures of business activities, such as revenue, labor dollars, customers, other operating and maintenance expense, construction expense, leased property, taxes, or functional surveys. For example, customer receivables are allocated based on revenue, and pension provisions are allocated based on labor dollars.

Inter-segment sales and transfers are accounted for at current market prices and are eliminated in consolidated net income available to common stockholders by segment. Inter-segment sales and transfers were immaterial for all periods presented.

**18:&nbsp;&nbsp;&nbsp;&nbsp;Related-party Transactions—Consumers**

Consumers enters into a number of transactions with related parties in the normal course of business. These transactions include but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases of electricity from affiliates of NorthStar Clean Energy

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• payments to and from CMS Energy related to parent company overhead costs

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• payments of principal and interest when due to CMS Energy related to borrowings under certain credit agreements and CMS Energy's repurchase of Consumers' first mortgage bonds

Transactions involving power supply purchases from certain affiliates of NorthStar Clean Energy are based on state law and competitive bidding. The payment of parent company overhead costs is based on the use of accepted industry allocation methodologies. These payments are for costs that occur in the normal course of business. Purchases of power and capacity from affiliates of NorthStar Clean Energy totaled $94 million in 2025, $71 million in 2024, and $75 million in 2023.

Amounts payable to related parties for purchased power and other services were $19 million at December 31, 2025 and $20 million at December 31, 2024. Accounts receivable from related parties were $13 million at December 31, 2025 and $15 million at December 31, 2024.

CMS Energy has a demand note payable to the DB SERP rabbi trust. The demand note bears interest at an annual rate of 4.10 percent and has a maturity date of 2028. The portion of the demand note attributable to Consumers was recorded as a note receivable – related party on Consumers' consolidated balance sheets at December 31, 2025 and 2024. For more information about Consumers' note receivable – related party, see Note 7, Financial Instruments.

Consumers has a natural gas transportation agreement with a subsidiary of CMS Energy that extends through 2038, related to a pipeline owned by Consumers. For additional details about the agreement, see Note 9, Leases.

CMS Energy has repurchased certain of Consumers' first mortgage bonds. Interest payable to related parties was $9 million at December 31, 2025 and $7 million at December 31, 2024. For more information about these repurchases, see Note 5, Financings and Capitalization—CMS Energy's Purchase of Consumers' First Mortgage Bonds.

In December 2025, Consumers renewed a short-term credit agreement with CMS Energy, permitting Consumers to borrow up to $500 million. For additional details about the agreement, see Note 5, Financings and Capitalization—Short-term Borrowings.

**19:&nbsp;&nbsp;&nbsp;&nbsp;Variable Interest Entities**

**Consolidated VIEs:** In March 2025, NorthStar Clean Energy sold a 50-percent interest in NWO Wind Equity Holdings for net proceeds of $36 million. NWO Wind Equity Holdings holds the Class B membership interest in NWO Holdco, the holding company of a 100-MW wind project located in Paulding County, Ohio. Additionally in March 2025, NorthStar Clean Energy sold a 50-percent interest in Delta Solar Equity Holdings for net proceeds of $8 million. Delta Solar Equity Holdings is the holding company of a 24-MW solar project located in Delta Township, Michigan.

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 consolidates these and other entities that it does not wholly own, but for which it manages and controls the entities' operating activities. NorthStar Clean Energy is the primary beneficiary of these entities because it has the power to direct the activities that most significantly impact the economic performance of the companies, as well as the obligation to absorb losses or the right to receive benefits from the companies. Presented in the following table is information about the VIEs NorthStar Clean Energy consolidates:

---

| | | |
|:---|:---|:---|
| Consolidated VIE | NorthStar Clean Energy's ownership interest | Description of VIE |
| Aviator Wind Equity Holdings | 51-percent ownership interest<sup>1</sup> | &nbsp;&nbsp;&nbsp;Holds a Class B membership interest in Aviator Wind |
| Aviator Wind | Class B membership interest<sup>2</sup> | &nbsp;&nbsp;&nbsp;Holding company of a 525-MW wind generation project in Coke County, Texas |
| BG Solar Holdings | Class B membership interest<sup>2</sup> | &nbsp;&nbsp;&nbsp;Holding company of a 200-MW solar generation project in Branch County, Michigan |
| Delta Solar Equity Holdings | 50-percent ownership interest<sup>1</sup> | &nbsp;&nbsp;&nbsp;Holding company of a 24-MW solar generation project in Delta Township, Michigan |
| Newport Solar Holdings | Class B membership interest<sup>2</sup> | Holding company of a 180-MW solar generation project in Jackson County, Arkansas |
| NWO Wind Equity Holdings | 50-percent ownership interest<sup>1</sup> | Holds a Class B membership interest in NWO Holdco |
| NWO Holdco | Class B membership interest<sup>2</sup> | &nbsp;&nbsp;&nbsp;Holding company of a 100-MW wind generation project in Paulding County, Ohio |

---

<sup>1</sup>The remaining ownership interest is presented as noncontrolling interest on CMS Energy's consolidated balance sheets.

<sup>2</sup>The Class A membership interest in the entity is held by a tax equity investor and is presented as noncontrolling interest on CMS Energy's consolidated balance sheets. Under the associated limited liability company agreement, the tax equity investor is guaranteed preferred returns from the entity.

Earnings, tax attributes, and cash flows generated by the entities in which NorthStar Clean Energy holds a Class B membership are allocated among and distributed to the membership classes in accordance with

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

the ratios specified in the associated limited liability company agreements; these ratios change over time and are not representative of the ownership interest percentages of each membership class. Since these entities' income and cash flows are not distributed among their investors based on ownership interest percentages, NorthStar Clean Energy allocates the entities' income (loss) among the investors by applying the hypothetical liquidation at book value method. This method calculates each investor's earnings based on a hypothetical liquidation of the entities at the net book value of underlying assets as of the balance sheet date. The liquidation tax gain (loss) is allocated to each investor's capital account, resulting in income (loss) equal to the period change in the investor's capital account balance.

Presented in the following table are the carrying values of the VIEs' assets and liabilities included on CMS Energy's consolidated balance sheets:

---

| &nbsp;&nbsp;&nbsp;Other non-current liabilities | 3 |  |
| Total liabilities | $292 | $64 |

---

<sup>1</sup>Assets may be used only to meet VIEs' obligations and commitments.

NorthStar Clean Energy is obligated under certain indemnities that protect the tax equity investors against losses incurred as a result of breaches of representations and warranties under the associated limited liability company agreements. For additional details on these indemnity obligations, see Note 4, Contingencies and Commitments—Guarantees.

Consumers' wholly-owned subsidiaries, Consumers 2014 Securitization Funding and Consumers 2023 Securitization Funding, are VIEs designed to collateralize Consumers' securitization bonds. These entities are considered VIEs primarily because their equity capitalization is insufficient to support their operations. Consumers is the primary beneficiary of and consolidates these VIEs, as it has the power to direct the activities that most significantly impact the economic performance of the companies, as well as the obligation to absorb losses or the right to receive benefits from the companies. The VIEs' primary assets and liabilities comprise non-current regulatory assets and long-term debt. For more information on

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

these assets and liabilities, see Note 3, Regulatory Matters—Securitized Costs and Note 5, Financings and Capitalization—Securitization Bonds

**Non-consolidated VIEs:** NorthStar Clean Energy has variable interests in T.E.S. Filer City, Grayling, Genesee, and Craven. While NorthStar Clean Energy owns 50 percent of each partnership, it is not the primary beneficiary of any of these partnerships because decision making is shared among unrelated parties, and no one party has the ability to direct the activities that most significantly impact the entities' economic performance, such as operations and maintenance, plant dispatch, and fuel strategy. The partners must agree on all major decisions for each of the partnerships.

Presented in the following table is information about these partnerships, which are accounted for using the equity method:

---

| | | |
|:---|:---|:---|
| Name | Nature of the Entity | Nature of NorthStar Clean Energy's Involvement |
| T.E.S. Filer City | Coal-fueled power generator | Long-term PPA between partnership and Consumers |
| T.E.S. Filer City | Coal-fueled power generator | Employee assignment agreement |
| T.E.S. Filer City | Coal-fueled power generator |  |
| Grayling | Wood waste-fueled power generator | Long-term PPA between partnership and Consumers |
| Grayling | Wood waste-fueled power generator | Reduced dispatch agreement with Consumers<sup>1</sup> |
| Grayling | Wood waste-fueled power generator | Operating and management contract |
| Grayling | Wood waste-fueled power generator |  |
| Genesee | Wood waste-fueled power generator | Long-term PPA between partnership and Consumers |
| Genesee | Wood waste-fueled power generator | Reduced dispatch agreement with Consumers<sup>1</sup> |
| Genesee | Wood waste-fueled power generator | Operating and management contract |
| Genesee | Wood waste-fueled power generator |  |
| Craven | Wood waste-fueled power generator | Operating and management contract |
| Craven | Wood waste-fueled power generator |  |

---

<sup>1</sup>Reduced dispatch agreements allow the facilities to be dispatched based on the market price of power compared with the cost of production of the plants. This results in fuel cost savings that each partnership shares with Consumers' customers.

The creditors of these partnerships do not have recourse to the general credit of CMS Energy, NorthStar Clean Energy, or Consumers. NorthStar Clean Energy's maximum risk exposure to these partnerships is generally limited to its investment in the partnerships, which is included in investments on CMS Energy's consolidated balance sheets in the amount of $54 million at December 31, 2025 and $64 million at December 31, 2024.

**20:&nbsp;&nbsp;&nbsp;&nbsp;Exit Activities and Asset Sales**

**J.H. Campbell Retirement:** Under its integrated resource plan, Consumers had planned to retire J.H. Campbell in 2025. In order to ensure necessary staffing at J.H. Campbell through the planned retirement, Consumers implemented a retention incentive program. Consumers made final payments under this retention plan in November 2025. The aggregate cost of this program was $48 million, which has been deferred as a regulatory asset. The MPSC has approved recovery of these retention costs over three years.

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 information on the emergency orders associated with J.H. Campbell, see Note 3, Regulatory Matters.

Presented in the following table is a reconciliation of the retention benefit liability recorded in other current liabilities on Consumers' consolidated balance sheets:

---

| | | |
|:---|:---|:---|
| *In Millions* | *In Millions* | *In Millions* |
| Year Ended December 31 | 2025 | 2024 |
| Retention benefit liability at beginning of period | $14 | $16 |
| Costs deferred as a regulatory asset | 7 | 8 |
| Costs paid or settled | (19) | (10) |
| Retention benefit liability at the end of the period | $2 | $14 |

---

**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.

**Report of Independent Registered Public Accounting Firm**

To the Board of Directors and Stockholders of CMS Energy Corporation

***Opinions on the Financial Statements and Internal Control over Financial Reporting***

We have audited the accompanying consolidated balance sheets of CMS Energy Corporation and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of income, of comprehensive income, of changes in equity and of cash flows for each of the three years in the period ended December 31, 2025, including the related notes and financial statement schedules listed in the index appearing under Item 15 (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the COSO.

***Basis for Opinions***

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

***Definition and Limitations of Internal Control over Financial Reporting***

A company'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 generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

***Critical Audit Matters***

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

*Accounting for the Effects of New Regulatory Matters*

As described in Note 3 to the consolidated financial statements, the Company is a utility and must apply regulatory accounting when its rates are designed to recover specific costs of providing regulated services. Under regulatory accounting, the Company records regulatory assets or liabilities for certain transactions that would have been treated as expense or revenue by a non-regulated business. As of December 31, 2025 the Company has recognized a total of $3,459 million of regulatory assets, $4,176 million of regulatory liabilities, $38 million of accrued revenues, and $28 million of accrued rate refunds. As described by management, there are multiple participants to rate case proceedings who often challenge various aspects of those proceedings, including the prudence of the Company's policies and practices. These participants often seek cost disallowances and other relief and have appealed significant decisions reached by the regulators. The recovery of regulatory assets and the settlement of regulatory liabilities are contingent upon the outcomes of rate cases and regulatory proceedings. The principal considerations for our determination that performing procedures relating to accounting for the effects of new regulatory matters is a critical audit matter are (i) the high degree of auditor judgment and subjectivity applied to evaluate management's assessment of the potential outcomes and related accounting impacts associated with pending rate case proceedings; (ii) in some cases, the significant audit effort necessary to assess contrary evidence from various parties involved in rate case proceedings; and (iii) the significant audit effort necessary to evaluate audit evidence related to the recovery of regulatory assets and the settlement of regulatory liabilities. Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to

------

<u>[**Table of Contents**](#ifde718d165614e8c9bb0a5066b000edc_34)</u>

management's assessment of regulatory proceedings, including the probability of recovering incurred costs and the related accounting and disclosure impacts. These procedures also included, among others, (i) evaluating the Company's correspondence with regulators; (ii) evaluating the reasonableness of management's assessment regarding whether recovery of regulatory assets and settlement of regulatory liabilities is probable; (iii) evaluating the sufficiency of the disclosures in the consolidated financial statements; and (iv) testing, on a sample basis, the regulatory assets and liabilities, including those subject to pending rate cases and regulatory proceedings, based on (a) provisions and formulas outlined in rate orders; (b) other regulatory correspondence; and (c) application of relevant regulatory precedents.

**Item 9.&nbsp;&nbsp;&nbsp;&nbsp;Changes in and Disagreements with Accountants on Accounting and Financial Disclosure**

None.

**Item 9A.&nbsp;&nbsp;&nbsp;&nbsp;Controls and Procedures**

**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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of CMS Energy

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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

**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). Based on such evaluation, Consumers' CEO and CFO have concluded that its disclosure controls and procedures were effective as of December 31, 2025.

**Notes to the Condensed Financial Statements**

**1:&nbsp;&nbsp;&nbsp;&nbsp;Basis of Presentation**

CMS Energy's condensed financial statements have been prepared on a parent-only basis. In accordance with Rule 12-04 of Regulation S-X, these parent-only financial statements do not include all of the information and notes required by GAAP for annual financial statements, and therefore these parent-only financial statements and other information included should be read in conjunction with CMS Energy's audited consolidated financial statements contained within Item 8. Financial Statements and Supplementary Data.

**2:&nbsp;&nbsp;&nbsp;&nbsp;Guarantees**

CMS Energy has issued guarantees with a maximum potential obligation of $1.3 billion on behalf of some of its wholly owned subsidiaries and related parties. CMS Energy's maximum potential obligation consists primarily of potential payments:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to third parties under certain commodity purchase and sales agreements entered into by CMS ERM and other subsidiaries of NorthStar Clean Energy

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to tax equity investors that hold membership interests in certain VIEs held by NorthStar Clean Energy

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to EGLE on behalf of CMS Land and CMS Capital, for environmental remediation obligations at Bay Harbor

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to the DOE on behalf of Consumers, in connection with Consumers' 2011 settlement agreement with the DOE regarding damages resulting from the department's failure to accept spent nuclear fuel from nuclear power plants formerly owned by Consumers

The expiration dates of these guarantees vary, depending upon contractual provisions or upon the statute of limitations under the relevant governing law.

CONSUMERS ENERGY COMPANY

FIRST MORTGAGE BOND 2025-2 COLLATERAL SERIES (INTEREST BEARING)

This bond is one of the bonds of a series designated as First Mortgage Bonds, 2025-2 Collateral Series (Interest Bearing) (sometimes herein referred to as the "<u>2025-2 Collateral Bonds</u>") issued under and in accordance with and secured by an Indenture dated as of September 1, 1945, given by the Company (or its predecessor, Consumers Power Company, a Maine corporation) to City Bank Farmers Trust Company (The Bank of New York Mellon, successor) (hereinafter sometimes referred to as the "<u>Trustee</u>"), together with indentures supplemental thereto, heretofore or hereafter executed, to which indenture and indentures supplemental thereto (hereinafter referred to collectively as the "<u>Indenture</u>") reference is hereby made for a description of the property mortgaged and pledged, the nature and extent of the security and the rights, duties and immunities thereunder of the Trustee and the rights of the holders of said bonds and of the

------

Trustee and of the Company in respect of such security, and the limitations on such rights. By the terms of the Indenture, the bonds to be secured thereby are issuable in series which may vary as to date, amount, date of maturity, rate of interest and in other respects as provided in the Indenture.

The 2025-2 Collateral Bonds are to be issued and delivered to the Agent in order to evidence and secure the obligation of the Company under the Agreement to make payments to the Banks under the Agreement and to provide the Banks the benefit of the lien of the Indenture with respect to the 2025-2 Collateral Bonds.

The obligation of the Company to make payments with respect to the principal of 2025-2 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due principal of the Reimbursement Obligations included in the Obligations shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the Reimbursement Obligations means that if any payment is made on the principal of the Reimbursement Obligations, a corresponding payment obligation with respect to the principal of the 2025-2 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the Reimbursement Obligations discharges the outstanding obligation with respect to such Reimbursement Obligations. No such payment of principal shall reduce the principal amount of the 2025-2 Collateral Bonds.

The obligation of the Company to make payments with respect to the interest on 2025-2 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due interest and/or fees under the Agreement shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the interest and/or fees under the Agreement means that if any payment is made on the interest and/or fees under the Agreement, a corresponding payment obligation with respect to the interest on the 2025-2 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the interest and/or fees under the Agreement discharges the outstanding obligation under the Agreement with respect to such interest and/or fees.

The Trustee may at any time and all times conclusively assume that the obligation of the Company to make payments with respect to the principal of and interest on this bond, so far as such payments at the time have become due, has been fully satisfied and discharged unless and until the Trustee shall have received a written notice from the Agent stating (i) that timely payment of principal and interest on the 2025-2 Collateral Bonds has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the Agent in connection with the Obligations pursuant to the Agreement, and (iii) the amount of the arrearage.

If an Event of Default (as defined in the Agreement) with respect to the payment of the principal of the Reimbursement Obligations shall have occurred, it shall be deemed to be a default for purposes of Section 11.01 of the Indenture in the payment of the principal of the 2025-2 Collateral Bonds equal to the amount of such unpaid principal (but in no event in excess of the principal amount of the 2025-2 Collateral Bonds). If an Event of Default (as defined in the Agreement) with respect to the payment of interest on the Reimbursement Obligations or any

------

fees shall have occurred, it shall be deemed to be a default for purposes of Section 11.01 of the Indenture in the payment of the interest on the 2025-2 Collateral Bonds equal to the amount of such unpaid interest or fees.

This bond is not redeemable except upon written demand of the Agent following the occurrence of an Event of Default under the Agreement and the acceleration of the Obligations, as provided in Section 9.2 of the Agreement. This bond is not redeemable by the operation of the improvement fund or the maintenance and replacement provisions of the Indenture or with the proceeds of released property or in any other manner except as set forth above.

In case of certain defaults as specified in the Indenture, the principal of this bond may be declared or may become due and payable on the conditions, at the time, in the manner and with the effect provided in the Indenture. The holders of certain specified percentages of the bonds at the time outstanding, including in certain cases specified percentages of bonds of particular series, may in certain cases, to the extent and as provided in the Indenture, waive certain defaults thereunder and the consequences of such defaults.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than seventy-five per centum in principal amount of the bonds (exclusive of bonds disqualified by reason of the Company's interest therein) at the time outstanding, including, if more than one series of bonds shall be at the time outstanding, not less than sixty per centum in principal amount of each series affected, to effect, by an indenture supplemental to the Indenture, modifications or alterations of the Indenture and of the rights and obligations of the Company and the rights of the holders of the bonds and coupons; provided, however, that no such modification or alteration shall be made without the written approval or consent of the holder hereof which will (a) extend the maturity of this bond or reduce the rate or extend the time of payment of interest hereon or reduce the amount of the principal hereof, or (b) permit the creation of any lien, not otherwise permitted, prior to or on a parity with the lien of the Indenture, or (c) reduce the percentage of the principal amount of the bonds the holders of which are required to approve any such supplemental indenture.

The Company reserves the right, without any consent, vote or other action by holders of the 2025-2 Collateral Bonds or any other series created after the Sixty-eighth Supplemental Indenture, to amend the Indenture to reduce the percentage of the principal amount of bonds the holders of which are required to approve any supplemental indenture (other than any supplemental indenture which is subject to the proviso contained in the immediately preceding sentence) (a) from not less than seventy-five per centum (including sixty per centum of each series affected) to not less than a majority in principal amount of the bonds at the time outstanding or (b) in case fewer than all series are affected, not less than a majority in principal amount of the bonds of all affected series, voting together.

No recourse shall be had for the payment of the principal of or interest on this bond, or for any claim based hereon, or otherwise in respect hereof or of the Indenture, to or against any incorporator, stockholder, director or officer, past, present or future, as such, of the Company, or of any predecessor or successor company, either directly or through the Company, or such predecessor or successor company, or otherwise, under any constitution or statute or rule of law, or by the enforcement of any assessment or penalty, or otherwise, all such liability of

------

incorporators, stockholders, directors and officers, as such, being waived and released by the holder and owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Indenture.

This bond shall be exchangeable for other registered bonds of the same series, in the manner and upon the conditions prescribed in the Indenture, upon the surrender of such bonds at the Investor Services Department of the Company, as transfer agent. However, notwithstanding the provisions of Section 2.05 of the Indenture, no charge shall be made upon any registration of transfer or exchange of bonds of said series other than for any tax or taxes or other governmental charge required to be paid by the Company.

The Agent shall surrender this bond to the Trustee when all of the principal of and interest on the Reimbursement Obligations arising under the Agreement, and all of the fees payable pursuant to the Agreement with respect to the Obligations, shall have been duly paid, and the Agreement (including, without limitation, all Commitments thereunder) shall have been terminated.

[END OF FORM OF REGISTERED BOND

OF THE 2025-2 COLLATERAL BONDS]

AND WHEREAS all acts and things necessary to make the 2025-2 Collateral Bonds (the "<u>Collateral Bonds</u>"), when duly executed by the Company and authenticated by the Trustee or its agent and issued as prescribed in the Indenture, as heretofore supplemented and amended, and this Supplemental Indenture, the valid, binding and legal obligations of the Company, and to constitute the Indenture, as supplemented and amended as aforesaid, as well as by this Supplemental Indenture, a valid, binding and legal instrument for the security thereof, have been done and performed, and the creation, execution and delivery of this Supplemental Indenture and the creation, execution and issuance of bonds subject to the terms hereof and of the Indenture, as so supplemented and amended, have in all respects been duly authorized;

NOW, THEREFORE, in consideration of the premises, of the acceptance and purchase by the holders thereof of the bonds issued and to be issued under the Indenture, as supplemented and amended as above set forth, duly paid by the Trustee to the Company, and of other good and valuable considerations, the receipt whereof is hereby acknowledged, and for the purpose of securing the due and punctual payment of the principal of and premium, if any, and interest on all bonds now outstanding under the Indenture and the $100,000,000 principal amount of the Collateral Bonds and all other bonds which shall be issued under the Indenture, as supplemented and amended from time to time, and for the purpose of securing the faithful performance and observance of all covenants and conditions therein, and in any indenture supplemental thereto, set forth, the Company has given, granted, bargained, sold, released, transferred, assigned, hypothecated, pledged, mortgaged, confirmed, set over, warranted, alienated and conveyed and by these presents does give, grant, bargain, sell, release, transfer, assign, hypothecate, pledge, mortgage, confirm, set over, warrant, alienate and convey unto The Bank of New York Mellon, as Trustee, as provided in the Indenture, and its successor or successors in the trust thereby and hereby created and to its or their assigns forever, all the right, title and interest of the Company in and to all the property, described in Section 11 hereof, together (subject to the provisions of

------

Article X of the Indenture) with the tolls, rents, revenues, issues, earnings, income, products and profits thereof, excepting, however, the property, interests and rights specifically excepted from the lien of the Indenture as set forth in the Indenture;

TOGETHER WITH all and singular the tenements, hereditaments and appurtenances belonging or in any wise appertaining to the premises, property, franchises and rights, or any thereof, referred to in the foregoing granting clause, with the reversion and reversions, remainder and remainders and (subject to the provisions of Article X of the Indenture) the tolls, rents, revenues, issues, earnings, income, products and profits thereof, and all the estate, right, title and interest and claim whatsoever, at law as well as in equity, which the Company now has or may hereafter acquire in and to the aforesaid premises, property, franchises and rights and every part and parcel thereof;

SUBJECT, HOWEVER, with respect to such premises, property, franchises and rights, to excepted encumbrances as said term is defined in Section 1.02 of the Indenture, and subject also to all defects and limitations of title and to all encumbrances existing at the time of acquisition.

TO HAVE AND TO HOLD all said premises, property, franchises and rights hereby conveyed, assigned, pledged or mortgaged, or intended so to be, unto the Trustee, its successor or successors in trust and their assigns forever;

BUT IN TRUST, NEVERTHELESS, with power of sale for the equal and proportionate benefit and security of the holders of all bonds now or hereafter authenticated and delivered under and secured by the Indenture and interest coupons appurtenant thereto, pursuant to the provisions of the Indenture and of any supplemental indenture, and for the enforcement of the payment of said bonds and coupons when payable and the performance of and compliance with the covenants and conditions of the Indenture and of any supplemental indenture, without any preference, distinction or priority as to lien or otherwise of any bond or bonds over others by reason of the difference in time of the actual authentication, delivery, issue, sale or negotiation thereof or for any other reason whatsoever, except as otherwise expressly provided in the Indenture; and so that each and every bond now or hereafter authenticated and delivered thereunder shall have the same lien, and so that the principal of and premium, if any, and interest on every such bond shall, subject to the terms thereof, be equally and proportionately secured, as if it had been made, executed, authenticated, delivered, sold and negotiated simultaneously with the execution and delivery thereof;

AND IT IS EXPRESSLY DECLARED by the Company that all bonds authenticated and delivered under and secured by the Indenture, as supplemented and amended as above set forth, are to be issued, authenticated and delivered, and all said premises, property, franchises and rights hereby and by the Indenture and indentures supplemental thereto conveyed, assigned, pledged or mortgaged, or intended so to be, are to be dealt with and disposed of under, upon and subject to the terms, conditions, stipulations, covenants, agreements, trusts, uses and purposes expressed in the Indenture, as supplemented and amended as above set forth, and the parties hereto mutually agree as follows:

SECTION 1. There is hereby created a series of bonds (the "<u>2025-2 Collateral Bonds" or the "Collateral Bonds</u>") designated as hereinabove provided, which shall also bear the descriptive

------

title "First Mortgage Bond", and the forms thereof shall be substantially as hereinbefore set forth (collectively, the "<u>Sample Bond</u>"). The 2025-2 Collateral Bonds shall be issued in the aggregate principal amount of $100,000,000, shall mature on the Termination Date (as such term is defined in the Agreement) and shall be issued only as registered bonds without coupons in denominations of $1,000 and any multiple thereof. The serial numbers of the Collateral Bonds shall be such as may be approved by any officer of the Company, the execution thereof by any such officer either manually or by facsimile signature to be conclusive evidence of such approval. The Collateral Bonds are to be issued to and registered in the name of the Agent under the Agreement (as such terms are defined in the Sample Bond) to evidence and secure any and all Obligations (as such term is defined in the Agreement) of the Company under the Agreement.

The 2025-2 Collateral Bonds shall bear interest as set forth in the Sample Bond. The principal of and the interest on said bonds shall be payable as set forth in the Sample Bond.

The obligation of the Company to make payments with respect to the principal of 2025-2 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due principal of the Reimbursement Obligations included in the Obligations shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the Reimbursement Obligations means that if any payment is made on the principal of the Reimbursement Obligations, a corresponding payment obligation with respect to the principal of the 2025-2 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the Reimbursement Obligations discharges the outstanding obligation with respect to such Reimbursement Obligations. No such payment of principal shall reduce the principal amount of the 2025-2 Collateral Bonds.

The obligation of the Company to make payments with respect to interest on 2025-2 Collateral Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the then due interest and/or fees under the Agreement shall have been fully or partially paid. Satisfaction of any obligation to the extent that payment is made with respect to the interest and/or fees under the Agreement means that if any payment is made on the interest and/or fees under the Agreement, a corresponding payment obligation with respect to the interest on the 2025-2 Collateral Bonds shall be deemed discharged in the same amount as the payment with respect to the interest and/or fees under the Agreement discharges the outstanding obligation under the Agreement with respect to such interest and/or fees.

The Trustee may at any time and all times conclusively assume that the obligation of the Company to make payments with respect to the principal of and interest on the Collateral Bonds, so far as such payments at the time have become due, has been fully satisfied and discharged unless and until the Trustee shall have received a written notice from the Agent stating (i) that timely payment of principal and interest on the 2025-2 Collateral Bonds has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the Agent pursuant to the Agreement, and (iii) the amount of the arrearage.

The Collateral Bonds shall be exchangeable for other registered bonds of the same series, in the manner and upon the conditions prescribed in the Indenture, upon the surrender of such

------

bonds at the Investor Services Department of the Company, as transfer agent. However, notwithstanding the provisions of Section 2.05 of the Indenture, no charge shall be made upon any registration of transfer or exchange of bonds of said series other than for any tax or taxes or other governmental charge required to be paid by the Company.

SECTION 2. The Collateral Bonds are not redeemable by the operation of the maintenance and replacement provisions of this Indenture or with the proceeds of released property.

SECTION 3. Upon the occurrence of an Event of Default under the Agreement and the acceleration of the Obligations, the Collateral Bonds shall be redeemable in whole upon receipt by the Trustee of a written demand from the Agent stating that there has occurred under the Agreement both an Event of Default and a declaration of acceleration of the Obligations and demanding redemption of the Collateral Bonds (including a description of the amount of principal, interest and fees which comprise such Obligations). The Company waives any right it may have to prior notice of such redemption under the Indenture. Upon surrender of the Collateral Bonds by the Agent to the Trustee, the Collateral Bonds shall be redeemed at a redemption price equal to the aggregate amount of the Obligations subject to the receipt by the Trustee of the redemption price from the Company.

SECTION 4. The Company reserves the right, without any consent, vote or other action by the holder of the Collateral Bonds or of any subsequent series of bonds issued under the Indenture, to make such amendments to the Indenture, as supplemented, as shall be necessary in order to amend Section 17.02 to read as follows:

SECTION 17.02. With the consent of the holders of not less than a majority in principal amount of the bonds at the time outstanding or their attorneys-in-fact duly authorized, or, if fewer than all series are affected, not less than a majority in principal amount of the bonds at the time outstanding of each series the rights of the holders of which are affected, voting together, the Company, when authorized by a resolution, and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental indenture or modifying the rights and obligations of the Company and the rights of the holders of any of the bonds and coupons; provided, however, that no such supplemental indenture shall (1) extend the maturity of any of the bonds or reduce the rate or extend the time of payment of interest thereon, or reduce the amount of the principal thereof, or reduce any premium payable on the redemption thereof, without the consent of the holder of each bond so affected, or (2) permit the creation of any lien, not otherwise permitted, prior to or on a parity with the lien of this Indenture, without the consent of the holders of all the bonds then outstanding, or (3) reduce the aforesaid percentage of the principal amount of bonds the holders of which are required to approve any such supplemental indenture, without the consent of the holders of all the bonds then outstanding. For the purposes of this

------

Section, bonds shall be deemed to be affected by a supplemental indenture if such supplemental indenture adversely affects or diminishes the rights of holders thereof against the Company or against its property. The Trustee may in its discretion determine whether or not, in accordance with the foregoing, bonds of any particular series would be affected by any supplemental indenture and any such determination shall be conclusive upon the holders of bonds of such series and all other series. Subject to the provisions of Sections 16.02 and 16.03 hereof, the Trustee shall not be liable for any determination made in good faith in connection herewith.

Upon the written request of the Company, accompanied by a resolution authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of bondholders as aforesaid (the instrument or instruments evidencing such consent to be dated within one year of such request), the Trustee shall join with the Company in the execution of such supplemental indenture unless such supplemental indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture.

It shall not be necessary for the consent of the bondholders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such consent shall approve the substance thereof.

The Company and the Trustee, if they so elect, and either before or after such consent has been obtained, may require the holder of any bond consenting to the execution of any such supplemental indenture to submit his bond to the Trustee or to ask such bank, banker or trust company as may be designated by the Trustee for the purpose, for the notation thereon of the fact that the holder of such bond has consented to the execution of such supplemental indenture, and in such case such notation, in form satisfactory to the Trustee, shall be made upon all bonds so submitted, and such bonds bearing such notation shall forthwith be returned to the persons entitled thereto.

Prior to the execution by the Company and the Trustee of any supplemental indenture pursuant to the provisions of this Section, the Company shall publish a notice, setting forth in general terms the substance of such supplemental indenture, at least once in one daily newspaper of general circulation in each city in which the principal of any of the bonds shall be payable, or, if all bonds outstanding shall be registered bonds without coupons or coupon bonds registered as to principal, such notice shall be sufficiently given if mailed, first class, postage prepaid, and registered if the Company so elects, to each registered holder of bonds at the last address of such holder appearing on

------

the registry books, such publication or mailing, as the case may be, to be made not less than thirty days prior to such execution. Any failure of the Company to give such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture.

SECTION 5. As supplemented and amended as above set forth, the Indenture is in all respects ratified and confirmed, and the Indenture and all indentures supplemental thereto shall be read, taken and construed as one and the same instrument.

SECTION 6. Nothing contained in this Supplemental Indenture shall, or shall be construed to, confer upon any person other than a holder of bonds issued under the Indenture, as supplemented and amended as above set forth, the Company, the Trustee and the Agent, for the benefit of the Banks (as such term is defined in the Agreement), any right or interest to avail himself of any benefit under any provision of the Indenture, as so supplemented and amended.

SECTION 7. The Trustee assumes no responsibility for or in respect of the validity or sufficiency of this Supplemental Indenture or of the Indenture as hereby supplemented or the due execution hereof by the Company or for or in respect of the recitals and statements contained herein (other than those contained in the tenth and eleventh recitals hereof), all of which recitals and statements are made solely by the Company.

The Trustee shall have the right to accept and act upon instructions, including funds transfer instructions ("Instructions") given pursuant to this Supplemental Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing officers with the authority to provide such Instructions ("Authorized Officers") and containing specimen signatures of such Authorized Officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee Instructions using Electronic Means and the Trustee in its reasonable discretion elects to act upon such Instructions, the Trustee's understanding of such Instructions shall be deemed controlling in the absence of negligence or willful misconduct. The Company understands and agrees that the Trustee cannot determine the identity of the actual sender of such Instructions and that the Trustee shall conclusively presume that directions that purport to have been sent by an Authorized Officer listed on the incumbency certificate provided to the Trustee have been sent by such Authorized Officer. The Company shall be responsible for ensuring that only Authorized Officers transmit such Instructions to the Trustee and that the Company and all Authorized Officers are solely responsible to safeguard the use and confidentiality of applicable user and authorization codes, passwords and/or authentication keys upon receipt by the Company. In the absence of negligence or willful misconduct, the Trustee shall not be liable for any losses, costs or expenses arising directly or indirectly from the Trustee's reliance upon and compliance with such Instructions notwithstanding such directions conflict or are inconsistent with a subsequent written instruction. The Company agrees: (i) to assume all risks arising out of the use of Electronic Means to submit Instructions to the Trustee, including without limitation the risk of the Trustee acting on unauthorized Instructions, and the risk of interception and misuse by third parties; (ii) that it is fully informed of the protections and risks associated with the various methods of transmitting Instructions to the Trustee and that there may be more secure methods of transmitting Instructions than the method(s) selected by the Company; (iii) that the security

------

procedures (if any) to be followed in connection with its transmission of Instructions provide to it a commercially reasonable degree of protection in light of its particular needs and circumstances; and (iv) to notify the Trustee immediately upon learning of any compromise or unauthorized use of the security procedures.

"Electronic Means" shall mean the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the Trustee as available for use in connection with its services hereunder.

SECTION 8. This Supplemental Indenture may be simultaneously executed in several counterparts and all such counterparts executed and delivered, each as an original, shall constitute but one and the same instrument.

SECTION 9. In the event the date of any notice required or permitted hereunder shall not be a Business Day, then (notwithstanding any other provision of the Indenture or of any supplemental indenture thereto) such notice need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the date fixed for such notice. "Business Day" means, with respect to this Section 9, any day, other than a Saturday or Sunday, on which banks generally are open in New York, New York for the conduct of substantially all of their commercial lending activities and on which interbank wire transfers can be made on the Fedwire system.

SECTION 10. This Supplemental Indenture and the Collateral Bonds shall be governed by and deemed to be a contract under, and construed in accordance with, the laws of the State of Michigan, and for all purposes shall be construed in accordance with the laws of such state, except as may otherwise be required by mandatory provisions of law.
