Nebius's $5.75B Convertible Blitz: The Price of Building an AI Empire at Breakneck Speed

Nebius reports 454% revenue growth and $236M EBITDA profit, yet shares fall 28% on $5.75B convertible debt and dilution concerns.

There is a peculiar tension at the heart of Nebius's current market story. The company's second-quarter results read like something out of a hypergrowth fairytale, yet its share price has spent the past month moving in the opposite direction. That disconnect — between an operation firing on all cylinders and a balance sheet that has investors reaching for the antacids — is the real narrative of late summer 2026.

The Growth Machine Keeps Humming

Strip away the market noise and the fundamentals are genuinely striking. Revenue for Q2 surged 454% year-over-year to $582.3 million, while adjusted EBITDA swung from a $21 million loss to a $236.2 million profit. The annualized run-rate now sits at $3 billion, a 598% jump. Perhaps most tellingly, customers are paying upfront — more than $9 billion in prepayments is expected for 2026, covering an estimated 50% to 60% of planned capital expenditure.

The demand picture extends beyond the income statement. Nebius has raised its contracted power capacity target to 5 gigawatts by year-end, with auction prices for capacity climbing 15%. Four cloud deals, each averaging over $1 billion in volume, underscore just how desperate the market is for AI compute. When capacity sells out immediately and clients hand over cash in advance, that is evidence of real demand, not promotional storytelling.

The Capital Structure Question

Yet the market is fixated on something else entirely. Since the private convertible bond placement closed last Sunday, the stock has fallen 4.6%. The decline stretches to 19.8% since shareholders greenlit the AI-factory expansion roughly two weeks ago, and a steeper 28.1% since the Q2 earnings release three weeks back.

The convertible itself is a beast: $5.75 billion in total, split between $3.45 billion at 0.50% due 2030 and $2.3 billion at 4.50% due 2034. For a company of Nebius's size, that is an enormous debt load. Compounding the dilution concern, Nebius swapped $800 million of older convertibles — $400 million each from the 2029 and 2031 series — for approximately 15.8 million new Class A shares.

The arithmetic is straightforward: more debt, more potential dilution, and existing shareholders get a smaller slice of a pie that is growing quickly, but not yet quickly enough to offset the sting.

A Board Armed to the Teeth

The capital-raising push was no accident of timing. At the annual general meeting on August 25, shareholders handed management a remarkably broad mandate. Beyond the routine re-election of board and supervisory board members and the appointment of auditors, the board received authorization to issue new Class A shares, exclude subscription rights, buy back up to 20% of outstanding shares, and cancel roughly 2.2 million Class C shares held in treasury.

Securing the right to both massively dilute and massively repurchase in a single stroke is a signal of intent: management wants maximum flexibility, whatever the market throws at it. The sequencing — the AGM just days before the largest financing round in the company's history — suggests a board that planned its toolkit carefully.

Wall Street's Split Personality

Analysts cannot seem to agree on how to read the situation. Goldman Sachs raised its price target from $286 to $328 at the end of August, reaffirming a buy rating — a clear signal that at least part of the Street prioritizes operational momentum over dilution anxiety. Citigroup followed suit on August 25, bumping its target from $278 to $324 with a buy recommendation.

But the bull case has a vocal counterweight. Passage Research initiated coverage in early August with a sell rating and a $95 price target, implying roughly 49% downside from current levels. The firm's thesis runs directly against the official growth narrative: the worry that GPU capacity constraints will ease, creating an oversupply that could throttle future growth.

Where the Stock Stands Now

The recent price action reflects a market caught between these competing visions. Yesterday's 3.1% decline to €172.24 came amid a broader tech selloff — the Nasdaq Composite fell more than 1% — and high-multiple AI names bore the brunt. With annualized volatility at 164%, Nebius amplifies whatever the sector throws at it.

The stock now sits about 34% below its 52-week high of €261.00, yet remains far above the year's low of €53.50. Year-to-date, it is still up 134%. That spread tells the story of a name that has tripled over the past twelve months but is now wrestling with the consequences of its own ambition.

Whether the market ultimately rewards or punishes this flexibility will not be decided at a shareholder meeting. The answer lies in the next quarterly numbers — and whether the growth engine can keep outpacing the weight of the debt it now carries.
