CMS Energy Corporation (CMS) FY2025 Earnings Quality Report

Grade: F — Major Red Flags

Framework: Schilit *Financial Shenanigans* + Beneish M-Score + forensic accounting principles

Data: SEC EDGAR 10-K (Filed 2026-02-10) + Yahoo Finance

Auditor: PricewaterhouseCoopers LLP — Clean opinion (1 critical audit matter: accounting for effects of new regulatory matters)

One-line verdict: CMS Energy, the parent of Consumers Energy serving 6.8 million Michigan residents, recorded 5 red flags — but the A3 fail (revenue-CFFO divergence) is the only genuinely concerning signal in an otherwise solid utility. Revenue grew 13.6% to $8.5B while CFFO declined 5.7%, creating a revenue-cash divergence that warrants investigation. The other four fails are structural: negative FCF, minimal cash, and negative post-acquisition FCF. CMS also faces a unique Michigan regulatory situation: coal plant retirement was mandated but then temporarily reversed by U.S. Secretary of Energy emergency orders. PwC flagged $3.5B in regulatory assets and $4.2B in regulatory liabilities as the critical audit matter.

Business: Michigan's Primary Utility

CMS Energy is the parent holding company of Consumers Energy, a wholly-owned subsidiary that serves Michigan. From the 10-K, Consumers Energy operates both electric and natural gas distribution businesses.

CMS also has a non-utility subsidiary, NorthStar Clean Energy. From the 10-K: "CMS Energy is the parent holding company of several subsidiaries, including Consumers and NorthStar Clean Energy. None of CMS Energy, NorthStar Clean Energy, nor any of CMS Energy's other subsidiaries (other than Consumers) has any obligation in respect of Consumers' debt securities or preferred stock."

Employee Base

From the 10-K: At December 31, 2025, CMS Energy had 8,350 employees, with unions representing 44% of employees.

J.H. Campbell Coal Plant Emergency Orders

A striking disclosure in the 10-K: 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. From the 10-K: "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."

This is an unusual regulatory intervention — the federal government effectively forced CMS to continue operating a plant it had planned to retire, potentially adding operational costs that may or may not be fully recoverable through rates.

Revenue and Income

Revenue surged 13.6% but gross margin compressed from 42.7% to 41.5%. This margin compression while revenue grows is worth monitoring — it could reflect higher fuel costs from the emergency coal generation or pass-through commodity costs that inflate revenue without proportional margin improvement.

Cash Flow: Revenue-CFFO Divergence

The A3 fail is the genuine signal here: revenue grew 13.6% but CFFO declined 5.7%. The CFFO/NI ratio of 2.09 is still healthy (profits are backed by cash), but the divergence between revenue growth and cash flow decline suggests working capital absorption. Possible drivers include:

Financing Activities (from 10-K)

From the 10-K, CMS Energy's cash from financing activities was $2,240M in FY2025, up from $614M in FY2024. Key drivers: "Higher debt issuances $1,647 million" partially offset by "Higher debt retirements ($198 million)." CMS issued $1.6B+ in new debt in FY2025, reflecting the heavy CapEx funding needs.

The 18-Point Screening

Revenue Quality

A2 and A3 together form a concerning pattern. Rising DSO (+5 days), AR outpacing revenue, and declining CFFO while revenue grows strongly — this combination in a regulated utility could signal customer payment stress from higher rates, regulatory lag in cost recovery, or working capital inefficiency.

Expense Quality

B2 note: CapEx growing at twice the rate of revenue (27.1% vs 13.6%) is aggressive even by utility standards. This may reflect the clean energy transition, grid modernization, or infrastructure required by Michigan's 2023 Energy Law.

Cash Flow Quality

Balance Sheet

D1: Zero goodwill is notable — CMS has grown organically rather than through acquisitions. This is the cleanest goodwill position in this batch.

Acquisition & Manipulation

PwC Critical Audit Matter: New Regulatory Matters

From PwC's report: "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."

PwC noted the challenge: "there are multiple participants to rate case proceedings who often challenge various aspects of a rate case filing." The $7.6B in combined regulatory assets and liabilities (relative to CMS's total assets) is substantial and depends entirely on future regulatory outcomes.

Key Risks

1. Coal plant emergency orders. The forced continuation of coal generation at J.H. Campbell creates operational complexity and cost uncertainty. If these costs are not fully recoverable through rates, CMS faces earnings compression.

2. Michigan 2023 Energy Law. Michigan's aggressive clean energy legislation (Public Acts 229-235 of 2023) mandates significant investment in renewable generation and grid modernization.

3. Municipal competition threat. From the 10-K: "Michigan law allows municipalities to create, own, and operate utilities. If one or more municipalities in Consumers' service territory created a new or supplemental utility, or impaired the franchise under which Consumers serves customers in the municipality, it could have a material adverse effect on CMS Energy and Consumers."

4. Revenue-CFFO divergence. The 13.6% revenue growth paired with -5.7% CFFO decline needs monitoring in future quarters to determine if this is a timing issue or a structural cash conversion problem.

Altman Z-Score and F-Score

Summary

Grade: F — mostly structural, with one genuine revenue quality concern.

Four of CMS's five fails are structural utility features (negative FCF, low cash, post-acquisition FCF, AR trend). The genuine concern is the A3 fail: revenue growing 13.6% while CFFO declined 5.7%. This revenue-cash divergence, combined with CapEx growing at 27.1% and DSO rising 5 days, suggests CMS is investing aggressively (likely driven by Michigan's 2023 Energy Law mandates and grid modernization) while cash generation has not yet caught up. The zero-goodwill balance sheet and F-Score fraud probability of 0.17% provide reassurance that there is no manipulation — this is a timing/investment cycle issue to monitor.
