AI Analysis

AI-generated, general educational analysis — not personal investment advice.

As a value investor, I start with what is proven, and Energy Vault is still a promise. It sells utility-scale storage systems—B-Vault batteries, G-Vault gravity, H-Vault hydrogen/hybrid—plus software. The revenue history is erratic: fiscal 2023 revenue was $341.5M, fiscal 2024 fell to $46.2M, and fiscal 2025 rose to $203.7M. Losses have been persistent: net income was -$98.4M in fiscal 2023, -$135.8M in fiscal 2024, and -$103.6M in fiscal 2025, with diluted EPS of -$0.69, -$0.91, and -$0.65 respectively. In fiscal Q1 2026, the quarter ended 2026-03-31, revenue was $21.9M and net loss was $32.5M; in fiscal Q2 2026, ended 2026-06-30, revenue was $17.4M and net loss was $29.7M. So the business is not yet self-funding.

In plain English: Energy Vault makes large energy storage systems for power grids, using batteries, gravity, hydrogen, and software. The business is not strong yet: it has lost money for years and burned cash, although revenue jumped in fiscal 2025. At the $3.11 close on 2026-10-13, the price looks expensive compared with its assets and losses.
