The Convertible Hangover and the Goldman Cure: Nebius's Two-Week Whiplash
Published on 08/26/2026 at 03:20 | Redaktion boerse-global.de
For a company whose shares have tripled in a year, the past fortnight has felt less like a victory lap and more like a stress test. Nebius closed a $5.75 billion convertible bond sale on Monday, saw its stock shed roughly a quarter of its value in six trading days, and then watched Goldman Sachs ride to the rescue with a fresh price target. The whiplash is the story.
Goldman's Alexander Duval lifted his target from $286 to $328 — the highest on Wall Street — while reaffirming a buy rating. The stock responded with a 5.2 percent jump to €190.28. It was the latest in a string of bullish analyst calls, following DA Davidson's August 18 hike from $175 to $250.
The Financing That Spooked the Market
The convertible offering, first announced August 19 at $4.5 billion, was upsized to $5.75 billion before closing this week. It breaks down into two tranches: $3.45 billion at 0.50 percent interest maturing in 2030, and $2.3 billion at 4.50 percent maturing in 2034, plus a $750 million option exercise. Nebius also swapped $800 million of older bonds into 15.8 million Class A shares. Net proceeds came to $4.94 billion, earmarked largely for data center expansion.
The market's initial reaction was understandable: total debt now approaches roughly $12 billion against quarterly revenue of $582.3 million. BCA Research has warned explicitly against "neoclouds" like Nebius and CoreWeave, citing heavy leverage and potentially thin margins, and recommends Big Tech over infrastructure players.
But the bear case misses a crucial counterweight. Customer prepayments exceeding $9 billion are expected to cover 50 to 60 percent of construction costs in 2026, according to Wolfe Research. The backlog stands at $37.5 billion, underpinned by a Meta contract worth up to $27 billion and Microsoft commitments of up to $17.4 billion. This is not speculative financing — it is capacity being pre-sold before it exists.
Should investors sell immediately? Or is it worth buying Nebius?
The Operational Picture
The second-quarter numbers, released roughly two weeks before the convertible drama, told a growth story that the share price has since obscured. Revenue surged 454 percent to $582.3 million, beating the consensus estimate of $572.75 million. The AI cloud business grew 514 percent to $574.9 million, and adjusted EBITDA swung from a year-ago loss to a profit of $236.2 million — a 50 percent margin.
Annual recurring revenue jumped 598 percent to $3.0 billion. Management reaffirmed its full-year revenue guidance of $3.0 to $3.4 billion and raised its contracted power capacity target for end-2026 from four to over five gigawatts.
On the technology front, Nebius claims to be the first cloud provider to integrate Nvidia's new Groq 3 LPX chip into its "Token Factory," with a benchmark of 3,400 tokens per second. Nvidia touts up to 35 times higher inference efficiency per megawatt versus Blackwell — a figure not yet independently verified, but one that bolsters Nebius's positioning as a first-mover.
Execution Milestones
Two operational developments this month helped steady the narrative. On August 18, the Vineland Planning Board approved Phase 2 of the AI data center under construction in southern New Jersey. The 600,000-square-foot expansion is seen as critical to reducing execution risk on the $17.4 billion Microsoft cloud contract.
Five days earlier, Nebius struck a deal with Vantage Data Centers to install Nvidia-powered AI infrastructure at the CWL1 campus in Newport, Wales — the first commercial capacity commitment in the South Wales AI Growth Zone.
The Valuation Tightrope
Despite the recent recovery, the stock still trades about 27 percent below its 52-week high of €261.00 from June 22. From the 52-week low of €53.50 last September, the shares have more than tripled. Year-to-date, the gain stands at 159 percent; over twelve months, 212 percent.
The annualized 30-day volatility of 177 percent captures the tension: growth euphoria on one side, dilution and capital-need anxiety on the other. At roughly €51 billion in market capitalization, Nebius remains one of the most closely watched bets in the AI infrastructure space.
The current price of around €188.70 sits just under 3 percent below the 50-day average and roughly 28 percent below the peak — evidence that the market is still digesting the financing round even as the long-term trajectory remains intact. Investors here are buying a wager on the inference era of artificial intelligence, with all the upside and all the fragility that entails.
