Overview
- The regulatory filing Wednesday showed Situational Awareness accumulated a 5.6% position in Nebius, amounting to about 12.41 million Class A shares valued at roughly $2.86 billion using the reported closing price.
- The stake disclosure sent NBIS up roughly 11–12% in after‑hours and premarket trading as investors treated the passive purchase as an institutional endorsement.
- Nebius reported a blowout quarter that underpins market interest, with roughly $399 million in revenue (about a 684% year‑over‑year increase) and positive adjusted EBITDA.
- Management is executing an aggressive buildout that included $2.47 billion of Q1 investments and a $20–$25 billion capex target for 2026, while industry GPU shortages and power/site permitting remain operational constraints.
- Valuation and governance risks persist because the stock trades at an elevated P/E around 68x and insiders sold about $123.8 million of shares in the past three months, so investors should watch GPU supply, delivery on large contracts with Meta and Microsoft, and progress on power and permitting.
