Energy Vault Reports Third Quarter 2025 Financial Results
WESTLAKE VILLAGE, Calif.--( BUSINESS WIRE)--Energy Vault Holdings, Inc. (NYSE: NRGV) (“Energy Vault” or “the Company”), a leader in sustainable, grid-scale energy storage solutions, announced financial results for the third quarter ended September 30, 2025.
“Following a strong operational quarter, we made major progress on our ‘build-own-operate’ Asset Vault strategy, targeting 1.5 gigawatts of storage capacity within the inaugural fund, including the acquisition of an attractive 150 megawatt project in Texas and the closing of a $300 million non-dilutive preferred equity investment from Orion Infrastructure Capital (OIC),” said Robert Piconi, Chairman of the Board and CEO of Energy Vault. “Our commercial team also unlocked new regional markets and super high growth new market segments, including agreements with EU Green Energy and Crusoe, the AI Factory Company. Importantly, we also increased our cash balance by completing a $50 million non-dilutive financing facility that is incremental to the OIC funding. We are reaffirming full-year 2025 guidance for all key metrics, including our forecast to continue to grow our cash balance sequentially in 2025 projecting $75-$100 million in cash at the end of the year, which, together with our strong $920 million backlog, positions us well for continued growth in 2026 and beyond.”

Non-GAAP measures
Energy Vault has provided a reconciliation of net loss to adjusted EBITDA, with net loss being the most directly comparable GAAP measure, for the historical periods in this press release. Energy Vault has also provided a reconciliation of reported S&M, R&D and G&A expenses to adjusted S&M expenses, adjusted R&D expenses, and adjusted G&A expenses, respectively, and a reconciliation of reported operating expenses to adjusted operating expenses for the historical periods in this press release. A reconciliation of projected non-GAAP measures for the full-year 2024 has not been provided because certain information necessary to calculate such measures on a GAAP basis is not available without unreasonable efforts or dependent on the timing of future events outside of our control. Therefore, because of the uncertainty and variability of the nature of the amount of future adjustments, which could be significant, the Company is unable to provide a reconciliation for these forward-looking non-GAAP measures without unreasonable effort.
Developed pipeline represents uncontracted potential revenue from third-party projects where potential prospective customers have either awarded the Company a project or shortlisted the Company for consideration. It also includes potential tolling revenue from projects where the Company is in advanced negotiations to build, own, and operate energy storage systems. Developed pipeline is an internal management metric that we construct using information from our global sales team and is monitored by management to understand the potential anticipated growth of our Company and to estimate potential future revenue. Developed pipeline is influenced by the prevailing foreign exchange rates and equipment prices and may vary from period to period if these inputs change.
Backlog represents contracted but unrecognized revenue from third-party projects and services yet to be completed, unrecognized revenue or other income from IP licensing agreements, and unrecognized revenue from tolling arrangements for projects operated by Energy Vault or affiliates. Backlog includes any potential future variable payments from tolling and offtake arrangements that the Company believes is probable of being realized. Probable future variable payments are forecasted by an independent third-party firm using simulation software that factors in current and projected energy market dynamics, historical and forecasted volatility, and location specific data. The Company considers the low-end simulation results to be probable. Potential future IP royalties are not included in backlog. Backlog is a common measurement used in our industry. Our methodology for determining backlog may not, however, be comparable to the methodologies used by others.

Non-GAAP Financial Measures
To complement our condensed consolidated statements of operations, we use non-GAAP financial measures of adjusted selling and marketing (“S&M”) expenses, adjusted research and development (“R&D”) expenses, adjusted general and administrative (“G&A”) expenses, adjusted operating expenses, adjusted net loss, and adjusted EBITDA. Management believes that these non-GAAP financial measures complement our GAAP amounts and such measures are useful to securities analysts and investors to evaluate our ongoing results of operations when considered alongside our GAAP measures. The presentation of these non-GAAP measures is not meant to be considered in isolation or as an alternative to other measures of financial performance calculated in accordance with GAAP. These non-GAAP measures and their reconciliation to GAAP financial measures are shown below.

We present adjusted EBITDA, which is net loss excluding adjustments that are outlined in the quantitative reconciliation provided above, as a supplemental measure of our performance and because we believe this measure is frequently used by securities analysts, investors, and other interested parties in the evaluation of companies in our industry. The items excluded from adjusted EBITDA are excluded in order to better reflect our continuing operations.
In evaluating adjusted EBITDA, one should be aware that in the future we may incur expenses similar to the adjustments noted above. Our presentation of adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these types of adjustments. Adjusted EBITDA is not a measurement of our financial performance under GAAP and should not be considered as an alternative to net loss, operating loss, or any other performance measures derived in accordance with GAAP or as an alternative to cash flow from operating activities as a measure of our liquidity.
Our adjusted EBITDA measure has limitations as an analytical tool, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are:
Because of these limitations, adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to use to meet our obligations. You should compensate for these limitations by relying primarily on our GAAP results and using adjusted EBITDA only supplementally.
