Bought a new stock today: $NRGV.
An under-the-radar energy storage name I’ve just started researching.
At a simple level, Energy Vault stores electricity when there is excess supply and releases it when demand increases. This is critical because renewable energy sources like solar and wind are intermittent, and storage is what makes them usable at scale.
What makes this more interesting is the company’s shift toward owning and operating energy assets, which introduces recurring revenue instead of one-off project income.
Historically, Energy Vault generated lumpy, project-based revenue. It is now transitioning toward more predictable cash flows through its “Asset Vault” strategy, where it builds, owns, and operates storage assets rather than just delivering them.
Revenue reached about $203M in 2025, up over 340% year-over-year, and the company delivered its first positive EBITDA quarter in Q4.
The key driver behind that inflection is the backlog, which has expanded to roughly $1.3B, up over 300% year-over-year.
A major catalyst is its partnership with Crusoe Energy Systems. Energy Vault is now building power infrastructure for AI data centers. These deployments are expected to generate 10–20x higher EBITDA per MW compared to traditional storage projects.
AI data centers are increasingly power constrained. If Energy Vault can successfully serve that demand, it shifts into a higher-value infrastructure player directly exposed to AI-driven energy demand.
On top of that, the company is working on next-generation storage through sodium-ion battery partnerships, which could reduce costs and lower supply chain risk over time.
The balance sheet has also strengthened, with cash above $100M, providing runway to execute on this transition.
Putting it together, the bull case is straightforward.
This is a company that has already proven it can scale revenue, is turning profitable, and has a large and growing backlog. At the same time, it is moving into higher-value markets like AI infrastructure, where the economics are significantly more attractive.
The key risk remains execution. The company needs to convert backlog into cash flow and scale its asset ownership model without funding stress.
If that works, it shifts from a small speculative energy stock to an infrastructure platform exposed to two large structural trends: renewable energy buildout and AI-driven power demand.
Not financial advice. I’ve just started researching and this is my first purchase.
Market cap: $770M
Thanks to @Robin54573990 for bringing this ticker to my attention.
