Utilities: One C-Grade, Nineteen Failures

The utilities sector is broken. Nineteen F-grades, a -9.7% median margin, and 582x average debt-to-FCF ratio tell the full story.

Aureus Research·Apr 13, 2026

When we last looked at utilities, the sector was already struggling. The numbers have gotten worse.

Twenty companies analyzed. One C-grade. Nineteen F-grades. Median FCF margin of -9.7%. Average debt-to-FCF ratio of 582x. This isn't a sector with a few problem children. This is systemic failure.

The One Company That Works

NextEra Energy (NEE) stands alone with an 11.7% FCF margin and a C-grade. It's not a great grade, but in a sector where the median company burns cash, it's the only one clearing the 8% threshold for a utilities A-grade.

NEE is improving. The trend is moving in the right direction. The company generates positive free cash flow while most of its peers are running capital expenditure programs that consume every dollar of operating cash and then some.

The gap between NEE and the rest of the sector is staggering. The second-best FCF margin belongs to Public Service Enterprise Group (PEG) at 0.2%. That's not a typo. Zero point two percent. PEG earns an F-grade and is technically improving, but barely generating any cash relative to revenue.

The Bottom Is Deep

Xcel Energy (XEL) posts a -46.5% FCF margin. Sempra (SRE) and Dominion Energy (D) both sit at -44.1%. These aren't companies having a bad quarter. These are structural cash incinerators.

The business model is clear: utilities spend heavily on infrastructure, regulated rates provide steady revenue, and debt finances the gap between operating cash and capital expenditure. The problem shows up when capex stays elevated year after year and FCF never recovers.

XEL and SRE are both declining. The trends are getting worse, not better. D is technically improving, but improving from -44.1% doesn't mean much when the destination is still deeply negative.

The Debt Problem

The average debt-to-FCF ratio of 582x is not a useful number because many companies generate negative FCF. When your denominator is negative or near zero, the ratio explodes. But the directional message is clear: utilities carry enormous debt loads relative to the cash they produce.

Our grading system penalizes debt-to-FCF ratios above 7x. Most utilities would trigger the maximum penalty if they generated positive FCF at all. The sector's capital intensity makes leverage inevitable, but the current balance between debt and cash generation is broken.

Eight Improving, Eleven Declining

Eight companies show improving trends. Eleven are declining. One is stable. The improving names include some of the worst performers: Dominion Energy, CenterPoint Energy (CNP), and American Electric Power (AEP) are all improving while still posting double-digit negative margins.

Improving from terrible to slightly less terrible isn't a bullish signal. It's a sign that the previous quarter was even worse.

The declining names include Duke Energy (DUK), DTE Energy (DTE), and Southern Company (SO). These are large, established utilities with regulated revenue streams. The trend direction suggests capital expenditure isn't slowing and free cash flow isn't recovering.

What the Sector Model Breaks Down To

Utilities exist to provide essential services with regulated returns. The regulatory framework is supposed to ensure stable, predictable cash flows. In theory, high debt is manageable because revenue is protected.

In practice, the sector is burning through cash to maintain and upgrade infrastructure. Rate increases take time to secure and implement. Capital expenditure can't wait. The gap shows up as negative FCF.

For most companies, negative FCF for a quarter or two signals trouble. For utilities, it's the normal state. The sector has trained investors to focus on earnings and dividends instead of cash. Earnings include non-cash items. Dividends can be funded with debt.

Free cash flow doesn't lie. The sector is spending more than it generates.

The Investment Question

Utilities pay dividends. Many investors buy them for income and stability. The Aureus grading system doesn't care about dividends. It cares about whether a company generates cash.

Nineteen F-grades say the sector isn't generating cash. The debt-to-FCF ratios say the sector is funding operations and dividends with leverage. The trend breakdown says more companies are getting worse than better.

NEE is the only name worth considering based on fundamentals. Even there, an 11.7% margin and a C-grade don't scream opportunity. They scream "least bad option in a broken sector."

The Sector's Path Forward

Utilities need one of three things to improve: lower capital expenditure, higher rate approvals, or significantly improved operational efficiency. None of those are fast. Capex is driven by infrastructure needs and regulatory requirements. Rate increases require regulatory approval and public acceptance. Efficiency gains take time and investment.

The sector isn't going to collapse. The services are essential. The regulatory framework provides a floor. But essential services and regulatory protection don't automatically translate to strong cash generation.

Investors looking for FCF health should look elsewhere. The utilities sector earns its F-grades.
