Retention Incentive Program: Under its Clean Energy Plan, Consumers will retire the The retirement of J.H. Campbell coal-fueled generating units in 2025. In order is subject to ensure necessary staffing at J.H. Campbell through retirement, temporary extensions under emergency orders issued by the U.S. Secretary of Energy. As a result, Consumers has implemented a retention incentive program. The aggregate cost of the J.H. Campbell program through 2025 is estimated measures to be less than $50 million; Consumers ensure appropriate staffing levels and expects to recognize $5 incur up to $4 million during each 90‑day emergency order period. Consumers will seek recovery of these retention benefit costs in 2025. The MPSC has approved deferred accounting treatment from FERC, consistent with rate recovery sought for these costs; these expenses are deferred as a regulatory asset. other costs of complying with the emergency orders.

Consumers has announced a long-term strategy for delivering clean, reliable, resilient, and affordable energy, including a plan to end the use of coal in owned generation in 2025, and other subsidiaries of CMS Energy have plans to develop and operate clean energy assets. The MPSC, FERC, other regulatory authorities, or other third parties may prohibit, delay, or impair some or all of CMS Energy’s and Consumers’ planned acquisitions or development of owned or purchased electric generation and storage capacity. Consumers’ planned electric generation capacity, including renewable generation or storage projects, may be adversely impacted by interconnection delays at MISO or in the footprints of other regional transmission organizations, and/or by interconnection costs. CMS Energy and Consumers and its contractors may be unable to acquire, site, construct timely, and/or permit generation and storage capacity, including some or all of the generation and storage capacity proposed in Consumers’ plan. CMS Energy and Consumers’ ability to implement their plans may be affected by environmental regulations, global supply chain disruptions, import tariffs, and changes in the cost, availability, and supply of generation and storage capacity. While CMS Energy and Consumers continue to advocate for advances in commercially available technologies required to reduce or eliminate greenhouse gases on a cost-effective basis at scale, such advances are largely outside of CMS Energy’s and Consumers’ control. Advancements in technology related to items such as battery storage, carbon capture/storage, and electric vehicles may not become commercially available or economically feasible as projected. Customer programs such as energy efficiency and demand response may not realize the projected levels of customer participation.

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. As a co-owner of Ludington, Consumers would be liable for 51 percent of any such damages, if liability and damages were proven. The court denied the motion to dismiss filed by TAES and Toshiba. The parties are engaged in ongoing litigation, including discovery, pursuant to a court-ordered schedule. Consumers believes the counterclaims filed by TAES and Toshiba are without merit, but cannot predict the financial impact or outcome of this matter. An unfavorable outcome could have a material adverse effect on CMS Energy’s and Consumers’ financial condition, results of operations, or liquidity.

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. Cash and cash equivalents may also be restricted to pay other contractual obligations such as leasing of coal railcars. These amounts are classified as current assets since they relate to payments that could or will occur within one year.

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.

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.

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.

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.
