CoreWeave's interest bill of $846 million is four times its operating profit, even as revenue jumps 168%

CoreWeave reported third-quarter revenue of $3.661 billion on Tuesday, up 168% from $1.365 billion a year earlier, and raised its full-year guidance. CNBC reported that consensus was $3.55 billion in revenue. The stock closed at $48.73 and was trading at $49.60, up 1.8%, at 4:51 PM ET, according to Nasdaq.com. Those are the headline numbers, and they are good. The ones below them are the reason the stock has been under pressure.

The number behind the number

In the earnings release filed with the SEC, the income statement reads like this:

Operating income rose almost fourfold, which is the business working. But net interest expense rose by about 173%, a little faster than revenue, and it is 4.1 times operating income ($846 million divided by $207 million). Interest took 23.1% of revenue this quarter and 22.7% a year ago. Growth has not yet made the debt lighter relative to sales. It has kept pace with it.

The adjusted figures tell a similar story. Adjusted operating margin was 10%, down from 16% a year earlier, even though management called reaching double digits "a quarter ahead of plan." Adjusted EBITDA, which ignores depreciation and interest, was $2.256 billion, a 62% margin. The gap between that figure and the $207 million of operating income is depreciation on the data centers, and the gap between operating income and the net loss is interest.

The debt behind the interest

The balance sheet in the same release shows total debt (recourse and non-recourse, current and long-term) of $46.9 billion at September 30, against $21.4 billion at December 31, 2025. That is an increase of about 119% in nine months. Of it, $10.6 billion falls due within a year, compared with $4.1 billion of cash and $1.4 billion of restricted cash classed as current.

The company's own guidance says the bill grows: interest expense for the fourth quarter is expected at $1.05 billion to $1.15 billion, 24% to 36% above this quarter's $846 million. Using the nine-month revenue of $8.314 billion and the raised full-year range of $13.0 billion to $13.3 billion, the implied fourth-quarter revenue is $4.69 billion to $4.99 billion, so interest would run at roughly 21% to 24.5% of sales. That is our arithmetic from the company's figures, not a company forecast.

What management is leaning on

The release points to three sources of funding: financing backed by customer contracts, operating cash flow, and "approximately $9 billion in customer prepayments and deposits expected in the next three months alone." Revenue backlog was about $132.5 billion. Nine-month operating cash flow was $5.64 billion, while cash spent on property and equipment was $23.56 billion over the same period.

The company also set up its first at-the-market equity program, for up to 35 million Class A shares, and raised about $4.2 billion in convertible notes during the quarter. At Tuesday's closing price, 35 million shares would be worth roughly $1.7 billion, which gives a sense of the scale of that program (illustrative; the company has not said how much it will use). It raised the low end of 2026 capital spending guidance to $37 billion to $39 billion, from $35 billion to $39 billion, saying it expects to deliver infrastructure to customers sooner than planned.

Why the market cares about rates here

CNBC reported that the stock has lost more than 40% of its value in the past month as investors rotated away from AI infrastructure, that rising interest rates have pushed lenders out of the market, and that some CoreWeave bond yields recently topped 16%. We covered that credit stress earlier: see CoreWeave's bond yields at 14.8% and its credit default swaps. With the 10-year Treasury yield near 5% after Tuesday's hot inflation report, every dollar CoreWeave refinances costs more than the one it replaces.

The quarter answers one question: demand is real, with revenue up 168% and a larger backlog. It leaves another open, and it is the one the credit market is asking. Operating income of $207 million has to keep growing faster than a debt pile that more than doubled this year. Next quarter's interest line, and what the company pays on new borrowing, will show whether it does. Neocloud peer Nebius reports Thursday, per CNBC.
