NBIS Eyes Positive EBITDA in H2 2025: What Could Drive Growth?

Nebius Group N.V. (NBIS), an AI infrastructure provider, reported a 385% year-over-year revenue surge to $55.3 million in Q1 2025, projecting full-year revenues between $500 million and $700 million. The company anticipates a return to positive adjusted EBITDA in H2 2025, though it will remain negative for the full year, reflecting its aggressive growth strategy and an increased 2025 capital expenditure plan of $2 billion. NBIS is expanding its global AI cloud infrastructure and offerings, navigating a highly competitive landscape with significant capital investments from rivals like CoreWeave and Microsoft, who are also pouring billions into AI infrastructure despite varying profitability and leverage profiles.

Analysis

Nebius Group N.V. (NBIS) is in a phase of hyper-growth, evidenced by a 385% year-over-year revenue surge to $55.3 million in the first quarter of 2025 and an aggressive full-year revenue forecast of $500-$700 million. This expansion is fueled by an increased capital expenditure plan of $2 billion for 2025 and strategic initiatives including global data center expansion and the integration of advanced technologies like NVIDIA's GB200 Superchip. However, this growth comes at a significant near-term cost, as the company projects negative adjusted EBITDA for the full year 2025, despite anticipating a return to positive adjusted EBITDA in the second half. This highlights a capital-intensive strategy focused on capturing market share in the competitive AI infrastructure space. The competitive landscape is fierce, with CoreWeave reporting even faster revenue growth (420% YoY) and superior profitability (62% adjusted EBITDA margin), but at the cost of high leverage with $8.7 billion in debt. Meanwhile, established titan Microsoft, while highly profitable with a 45.7% operating margin, also signals margin pressure from its own substantial capital investments. Despite NBIS's strong stock performance, gaining 85.4% year-to-date, its valuation on a price/book basis remains below the industry average at 3.83X, and a Zacks Rank of #4 (Sell) suggests underlying investor concerns about its path to sustainable profitability amidst intense, capital-heavy competition.

Key Decisions for Investors

• Investors should closely monitor NBIS's execution on its $2 billion capital expenditure plan, specifically tracking its ability to meet the H2 2025 positive adjusted EBITDA target as a key proof point for its investment thesis.
• Given the intense capital race, consider the relative risk profile of NBIS against highly leveraged competitors like CoreWeave and the margin-pressured scale of Microsoft, assessing if NBIS's strategy can achieve competitive scale without compromising its balance sheet.
• The disparity between the stock's 85.4% year-to-date rally and its cautionary Zacks #4 (Sell) rating warrants a deeper investigation into the specific risks flagged by analysts, particularly concerning the timeline for achieving sustained profitability.
• Evaluate the company's progress toward its medium-term EBIT margin goal of 20-30% and look for qualitative data on customer retention, as these will be critical indicators of its long-term viability beyond the current high-growth, high-spend phase.
