Nebius Group is a pure-play AI-infrastructure (Neocloud) company, completing its transformation in 2024 after divesting its Russian assets from Yandex for ~$5.4B; it is headquartered in Amsterdam. Built on a self-developed full stack (the Aether cloud platform, the Token Factory inference platform, and owned data centers), it is a SemiAnalysis Gold Tier, Tier-1 Neocloud provider, leveraging a Finland PUE of 1.1 as an efficiency benchmark and a 20-25% TCO advantage. FY2025 revenue was $529.8M (+479% YoY), with a combined ~$46B backlog from Meta and Microsoft and a $2B strategic investment from NVIDIA; it also holds assets including Toloka, TripleTen, Avride, and a 28% stake in ClickHouse.
Current core thesis
A pure AI-infrastructure play: revenue up 25x in three years, ARR up 5x in 12 months to $1.25B, a ~$46B Meta+Microsoft backlog providing extreme revenue visibility, plus NVIDIA's $2B strategic investment and a full-stack TCO advantage. But ~92% customer concentration, an ISS governance score of 10/10, the CEO's 52% voting power, extreme 2026 capex of $16-20B, and ongoing dilution make it high-risk. At a TTM P/S of 87x, the valuation depends on executing revenue from $530M to ~$10B within two years. H1 2026 is the key verification window; the strategy is staged, small probing positions — accumulate on a pullback to $95-120 or ahead of catalysts, hard stop $75.
Forward catalysts
The first major verification catalyst: consensus revenue $378.8M (+585% YoY). Watch gross margin holding 68%+, the AI Cloud EBITDA-margin trend, and continued operating cash flow.
The Microsoft-dedicated site; the first 50MW is expected online in H1 2026, directly determining the Microsoft tranche-unlock cadence and capacity-expansion execution.
Advancing toward the 800MW-1GW target with accelerating revenue recognition; first integration of NVIDIA Vera Rubin in H2 2026.
A verification point for new-capacity availability and the ability to sign new customers.
Meta's $12B firm-commitment capacity on the Vera Rubin platform delivers from early 2027, driving the 2027E $9.5-11B revenue path.
