WESTLAKE VILLAGE, Calif., May 12th, 2025 – 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 first quarter ended March 31, 2025.

“We made good progress in the quarter across a series growth drivers including first battery project construction in Australia, a 10-year license of our innovative B-Vault battery hardware and software architecture to support local manufacturing in India given the growing market demand, and having our first wholly owned energy storage asset operating in the market in Texas,” said Robert Piconi, Chairman and CEO of Energy Vault. “Our geographic customer diversity and existing owned storage assets under operation and commissioning in Texas and California has helped to offset a very volatile U.S. market environment for new battery projects given recent China-US tariff disputes. Importantly, as expected, Q1 also saw the first project financing close and thus a 57% increase in total cash for the quarter with another roughly $45-50 million upcoming as we begin to return cash back on the balance sheet, including already executed contracts for monetization of our investment tax credits.”

•Contract revenue backlog reached $648 million, 49% higher year-to-date, and is largely shielded from U.S. tariff risks due to a strong Australian presence, license agreements and enhanced asset ownership, representing nearly 90% of the backlog today.

•Q1 2025 revenue, at $8.5 million, rose 10% year-over-year and was driven chiefly by Australian battery storage projects plus a high-margin licensing deal in India.

•Q1 2025 GAAP gross margin climbed to 57.1% from 26.7% a year ago, driven mainly by the favorable revenue mix stemming from the India license agreement.

•Q1 2025 cash finished at $47.2 million (including restricted cash), up approximately $17 million compared to $30.1 million at year-end 2024, reflecting proceeds from the Calistoga Resiliency Center (CRC) project financing.

•Q1 2025 GAAP operating expenses of $25.8 million and adjusted operating expenses of $16.2 million decreased by 3% and 4%, respectively, year-over-year reflecting disciplined cost-side management.

•Q1 2025 Net loss remained flat at ($21.1) million year-over-year

•Q1 2025 Adjusted EBITDA improved 22% to ($11.3) million from ($14.5) million year-over-year, aided by additional high-margin license revenue and reduced operating costs.

•Q1 2025 Adjusted Net loss improved 10% to ($11.7) million from ($13.0) million year-over-year.

•Energy Vault signs a 10-year, 30+ GWh license and royalty agreement with India’s SPML Infra to manufacture and deploy the B‑Vault battery energy storage technology platform.

•8.5 MW / 293 MWh Calistoga Resiliency Center (CRC) remains on track for commercial operation in June following the $28 million project financing with Eagle Point Capital announced previously.

•57 MW / 114 MWh Cross Trails project mechanically complete ahead of schedule and has begun revenue generation during the commissioning phase associated with the 10-year Gridmatic offtake agreement.

•Active projects continue to expand in Australia, including more than 2.6 GWh of projects in various stages of construction or development.

•Leveraging our global supply chain and manufacturing partnerships to reduce tariff impacts on U.S. customers.

•Near-term targets include reducing most recently reported quarterly adjusted operating expenses by 15-25% to a quarterly run rate of $12-14 million as compared to $16.2 million in Q1 2025 while continuing to invest in profitable engagements as Australia’s market demonstrates robust growth potential.

•The 57 MW / 114 MWh Cross Trails project financing is expected to close during Q2 2025, yielding approximately $20 million in gross proceeds (with an additional $12 million anticipated for the transfer/sale of the ITC under the IRA).

•Transfer and sale of three ITCs with a reputable buyer expected to generate proceeds in September in excess of $40 million (of which roughly $13 million of which are included in the CRC project financing structure and the $12 million associated with Cross Trails).

•Encouraging news today on China/U.S. Tariff pause; pending final positive resolution and timing, no change to current guidance, with potential revenue upside on accelerated U.S. battery deliveries in 2025.

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 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.

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:

•it does not reflect our cash expenditures, future requirements for capital expenditures, or contractual commitments;

•it does not reflect changes in, or cash requirements for, our working capital needs;

•it does not reflect stock-based compensation, which is an ongoing expense;

•although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and our adjusted EBITDA measure does not reflect any cash requirements for such replacements;

•it is not adjusted for all non-cash income or expense items that are reflected in our consolidated statements of cash flows;

•it does not reflect the impact of earnings or charges resulting from matters we consider not to be indicative of our ongoing operations;

•it does not reflect limitations on or costs related to transferring earnings from our subsidiaries to us; and

•other companies in our industry may calculate this measure differently than we do, limiting its usefulness as a comparative measure.

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.
