CMS Energy: Showing Its Work While the Market Grades the Election

A reaffirmed 6–8% plan, a $27B IRP, and a NorthStar cleanup—yet the stock is 12% off its spring peak as Michigan politics and rate-case math dominate.

A reaffirmation is not a victory lap

CMS Energy came into this print with the tape already skeptical: the shares were down 6.5% over 90 days and 12.4% below their June peak. The call did not offer a raise; it offered repetition. Management reaffirmed 2026 guidance of $3.83–$3.90, 2027 guidance of $4.08–$4.17, and the long-term 6–8% adjusted EPS growth target “toward the high end, which we framed up as 7% or better” — Garrick J. Rochow, President and Chief Executive Officer · 2026-10-27. In a market that has rewarded utility growth stories, a reaffirmation into a drawdown is its own signal. The new language was political, not financial. Garrick Rochow leaned on 23 years of delivery, but the freshest keyword in the transcript was common ground—specifically, common ground on affordability. He paired that with moderate income customers and multiyear rate plans, a framing that was not a top theme in the prior calls. That is a response to Michigan's election and the affordability debate, not a new EPS driver.

NorthStar: the cleanup is real, but not a surprise

The NorthStar restructuring was announced last quarter; this quarter provided progress. “As of today, we have more than 35% of the assets have signed agreements or closed” — Garrick J. Rochow, President and Chief Executive Officer · 2026-10-27, and management still expects the restructuring to be complete by year-end. CMS retains Dearborn Industrial Generation, several small gas peakers, and four commercial solar projects, while reducing more than $500 million of parent funding within the current five-year plan. The strategic payoff is a cleaner story: nearly 100% regulated utility earnings after 2027. But this is not a fresh catalyst. On the Q2 call, Rochow was explicit that the repositioning came with “no rebase. That's what you should see in there.” — Garrick Rochow, President and Chief Executive Officer · 2026-07-28 The market has had a quarter to digest it. Q3 simply reduced execution risk around a known event; it did not change the growth algorithm.

The IRP and FCM: the part management says is underestimated

The more interesting disclosure sits in the integrated resource plan filed in September. CMS outlined 15.8 GW of clean energy resources, 4.1 GW of battery storage, 1.4 GW of new simple-cycle gas, and roughly $27 billion of capital investment opportunity. It also disclosed a 680 MW clean energy PPA and, crucially, the financial compensation mechanism: $125 million beginning in 2031, growing to $195 million by 2040 on a 50% ownership assumption. Rochow put an unusual amount of weight on this—and on his mother's math-teacher instruction to show your work:

The short answer is we do not see the FCM going away. ... I think it is 1 of the things that is most underestimated by investors, that ability to grow FCM over time.
Garrick J. Rochow, President and Chief Executive Officer · 2026-10-27

That is a legitimate differentiator. The Resource Plan gives CMS a capital-light way to earn on power purchase agreements, and management says more than 70% of the 2031 FCM contracts are already signed or online. But the phrase 'do not see the FCM going away' also reveals the risk: the Michigan Public Service Commission has been discussing the mechanism, and the CEO is defending it. He called the debate 'refinement,' particularly around fully depreciated assets, not elimination. Investors should treat that as a regulatory headline risk rather than a base-case earnings cut.

Data centers: big option, deliberately outside the plan

The demand story remains the same: 745 MW of new contracts signed, 450 MW energized, and a large data center agreement progressing through zoning in multiple Michigan locations. But the capital plan still does not include it. CFO Srikanth Maddipati was clear: “our current plan does not really contemplate having a data center in it” — Srikanth Maddipati, Executive Vice President and Chief Financial Officer · 2026-10-27. The large load agreement is real optionality, not a 2027 earnings event. This is a familiar cadence. On the Q1 call, management said “the data centers are not in the plan” — Garrick Rochow, President and Chief Executive Officer · 2026-02-05. On Q2, the CFO noted “the capital plan that we have today doesn't reflect that load growth” — Srikanth Maddipati, Executive Vice President and Chief Financial Officer · 2026-07-28. The rule of thumb remains 1 GW of load for $2–$5 billion of capex. The large data center could eventually push rate base and sales growth above the current 2–3% load forecast, but the ramp is back-half-of-plan, and zoning is still a gating item. After the election, management expects more movement; until then, it is a call option the market has heard about for several quarters.

Rate-case math and the balance sheet

The near-term swing factor is regulation, not data centers. The gas rate case produced a constructive order: $139 million, a 9.8% ROE, and a 50% equity ratio. The electric case is the bigger one. CMS filed a revised $443 million request at a 10.25% ROE and 51.75% equity ratio; staff recommended $265 million, a 9.85% ROE, and 50% equity. A proposed final decision is expected in late January, with a final order by early April. The equity ratio matters because Moody's has the utility on negative outlook. Management acknowledged the agency will focus on rate recovery and the equity ratio in the electric case. That is the balance-sheet tension beneath the 6–8% story. Interest coverage is just 1.3x, down from 4.1x at its 2019 peak, while long-term debt has reached $18.2B. Capex continues to step up—$967M in the latest quarter—and operating margin has compressed to 14.4%. At roughly 23.4x earnings, CMS is not priced as broken, but it is not cheap enough to ignore the rate case. One small but telling detail: CMS trimmed its quarterly deck, removing the rate-base and data-center funnel slides that analysts have come to expect. When pressed, Rochow said, “There should be nothing you should read into this.” — Garrick J. Rochow, President and Chief Executive Officer · 2026-10-27 Maybe. But in a quarter where the stock is in a drawdown and the growth story depends on disclosures that were removed, the burden of proof shifts to the April order and the post-election regulatory calendar. CMS is still a high-quality regulated utility with a visible plan, a real FCM kicker, and a cleaner NorthStar story. But this report was a defense, not an offensive. The pieces are in place for 7%+ growth if Michigan regulation holds and the large-load option converts; the tape is saying 'show me' until it does.
