NBIS Q3 Earnings: Explosive Growth and Raised Guidance

Nebius Group reported a jaw-dropping 355% year-over-year revenue surge in Q3 2025, driven by surging demand for its AI and cloud infrastructure services. More impressively, management didn’t just celebrate—they raised their long-term Annual Recurring Revenue (ARR) and capacity guidance significantly, signaling strong confidence in future demand .

Unlike peers bogged down by supply chain bottlenecks or capital constraints, Nebius is scaling efficiently. Operating margins are expanding, and the company maintains a relatively lean debt profile—a rarity in the capital-intensive AI infrastructure space.

NBIS vs. CoreWeave: A Tale of Two Balance Sheets

When compared directly to CoreWeave (NASDAQ: CRWV), NBIS stock stands out for its financial prudence. CoreWeave, while also reporting strong top-line growth, faces mounting challenges: margin compression, heavy debt, and recent cuts to both guidance and capital expenditure plans .

In contrast, Nebius combines aggressive growth with a path to profitability. As one Seeking Alpha analyst noted, “NBIS’s financial health, growth trajectory, and margin improvements position it as the stronger investment” in the AI infrastructure race .

The Meta AI Deal: Catalyst or Distraction?

Market reaction to Nebius’s earnings was initially negative, with the stock falling despite strong fundamentals. Some analysts point to investor disappointment that a recently announced partnership with Meta—while strategically significant—wasn’t enough to offset near-term volatility or signal an immediate revenue inflection .

However, experts argue this deal is more about long-term positioning than short-term gains. Partnering with a tech giant like Meta validates Nebius’s technical capabilities and could open doors to other hyperscalers. It’s a building block, not a quick fix.

Key Risks Investors Shouldn’t Ignore

That said, investing in NBIS stock isn’t without risk. As The Motley Fool cautions, one “big thing to watch” is the company’s ability to consistently execute on its ambitious expansion plans .

Capital intensity: Building AI data centers requires massive upfront investment.
Competition: Giants like Amazon, Microsoft, and NVIDIA-backed players dominate the ecosystem.
Geopolitical exposure: Nebius has significant operations in Europe and emerging markets, which carry regulatory and currency risks.

Investors should monitor quarterly capital deployment and client diversification closely.

Analyst Outlook and Valuation Potential

Despite the post-earnings dip, sentiment among analysts remains bullish. One detailed valuation model suggests 75% upside potential for NBIS stock over the next two years, driven by ARR growth and margin expansion .

Where CoreWeave is labeled a “Hold” due to its leverage and execution risks, Nebius earns a clear “Buy” recommendation from several independent research firms. Its combination of growth, discipline, and strategic partnerships makes it a rare balanced player in a sector often dominated by hype over fundamentals.

Conclusion: A High-Growth AI Play with Substance

While the market may have overreacted to short-term noise, the fundamentals behind NBIS stock remain compelling. With explosive revenue growth, a lean balance sheet, and a strategic foothold in the AI infrastructure boom, Nebius Group is positioning itself not just as a participant—but as a potential leader—in the next wave of cloud and AI computing. For investors with a multi-year horizon, the current volatility may represent a buying opportunity in a high-conviction AI stock.
