WESTLAKE VILLAGE, Calif.--(BUSINESS WIRE)--March 17, 2026--
Energy Vault Holdings, Inc. (NYSE: NRGV) ("Energy Vault" or "the Company"), a leader in sustainable, grid-scale energy storage solutions, today announced financial results for the fourth quarter and year ended December 31, 2025.
"2025 marked a pivotal year of focused execution by our employees of our strategy and to our customers, in what started as one of the most volatile and challenging years that we faced as a company. Through a strong second half revenue ramp and project execution resulting in positive adjusted EBITDA in Q4, we significantly strengthened our balance sheet to support our Asset Vault and AI Digital Infrastructure growth initiatives while continuing to aggressively acquire 'megawatts' of projects within those sectors now totaling 540 MW from just 65 MW one year ago," said Robert Piconi, Chairman of the Board and CEO of Energy Vault. "During the year we advanced our Asset Vault strategy with new projects entering construction and operation, expanded our long-duration storage footprint in Australia and entered the rapidly growing AI infrastructure market through strategic partnerships with Crusoe and Peak Energy. We also secured rights to 500 acres of powered land in the US Southwest and are in discussions with leading neo-cloud providers and hyperscalers to deliver turnkey AI digital infrastructure. These milestones reinforce our strategy to deliver, own and operate mission-critical energy infrastructure supporting renewable generation, grid resiliency and the accelerating energy demands of AI computing."
"While we more than tripled our total cash balance to over $100 million and now guiding FY 2026 to $150 to $200 million, we also strengthened our financial foundation through several strategic financing initiatives, including the previously announced $300 million preferred equity fund supporting Asset Vault projects and the recently announced $150 million convertible notes offering, which enhances our liquidity and financial flexibility to accelerate our entry into the AI digital infrastructure sector. Together, these efforts position Energy Vault to scale recurring, highly profitable infrastructure revenues and deliver predictable and long-term value creation for shareholders."
Fourth Quarter and Full Year 2025 Financial Highlights
-- Contract revenue backlog as of December 31, 2025, grew significantly to
$1.3 billion, up 3x versus the prior year and up 42% sequentially versus
September 30, 2025. The backlog increase reflects strong growth in long
term energy storage service agreements for Asset Vault "own and operate"
projects in Australia and the U.S.
-- Q4 2025 revenue of $153.3 million was up significantly from $33.5
million in the prior-year period, driven by project execution in
Australia and the U.S. and initial contributions from Asset Vault
projects, including Calistoga and Cross Trails.
-- 2025 revenue of $203.7 million improved over 340% versus $46.2 million
the prior year (within the original 2025 revenue guidance range), driven
by increased battery energy storage project deliveries in Australia and
the U.S. and the commencement of operations from the initial own and
operate Asset Vault projects.
-- Q4 2025 GAAP gross profit of $31.6 million improved significantly from
$2.6 million in the prior year period driven by volume, project cost
reduction and stronger overall unit economics; Q4 2025 GAAP gross margin
was 20.6% versus 7.8% in the prior year period.
-- 2025 GAAP gross profit of $48.0 million improved nearly 8x versus the
prior year, driven by increased revenue, more efficient project execution
at reduced cost per unit and favorable business mix, resulting in 2025
gross margin of 23.6%, up over 10 percentage points versus 13.4% in the
prior year.
-- Q4 2025 GAAP Net Loss of $20.7 million improved by $41.1 million from a
loss of $61.8 million in the prior year period.
-- 2025 GAAP Net Loss of $103.6 million improved by $32.2 million from a
loss of $135.8 million the prior year.
-- Q4 2025 Adjusted EBITDA turned positive to $9.8 million, up from a loss
of $13.4 million in the prior year period, driven by higher revenue,
stronger unit economics and gross profit.
-- 2025 Adjusted EBITDA improved to a loss of $21.2 million, from a loss
of $58.0 million in the prior year, driven by higher revenue, stronger
gross margins from lower cost per unit project execution and lower
operating expenses.
-- Q4 2025 Adjusted Net Income also turned positive to $3.7 million versus
a loss of $25.0 million in the prior year period.
-- 2025 Adjusted Net Income improved to a loss of $42.1 million from a
loss of $65.4 million the prior year.
-- Total cash (including restricted cash) as of December 31, 2025, was
$103.4 million, up over 3x versus the prior year and up 67% sequentially
from Q3 2025, and above the previously issued guidance range.
-- In February 2026, Energy Vault completed a $150 million 5.250% Senior
Convertible Notes offering due 2031 (gross, upsized from $125 million),
with a portion of the proceeds used to implement a capped call (for an
implied conversion price of $8.12/share) and repayment of $45 million in
existing higher-cost principal debt.
Operating and Other Recent Highlights
-- In February 2026, entered into a strategic framework with Crusoe for
the phased deployment of Crusoe Spark modular data centers at Energy
Vault's technology center in Snyder, Texas. The initial program is
scalable up to 25 MW of total load to be operated inside Crusoe's
proprietary Spark modular AI factory product, with planned deployments
expected in 2026.
-- In February 2026, Energy Vault's Australian development partner, Bridge
Energy, was awarded a 14-year Long-Term Energy Service Agreement (LTESA)
by AusEnergy Services for the EBOR Battery Energy Storage System project
in New South Wales, Australia. The 100 MW / 870 MWh project is expected
to provide eight hours of dispatchable capacity and is expected to
commence operations in 2028, subject to obtaining necessary contractual
and regulatory approvals. Energy Vault holds an exclusive option to
acquire and construct the project, which will utilize its proprietary
B-VAULT technology and EMS, and will be owned and operated under the
Company's Asset Vault platform.
-- In February 2026, announced a definitive supply agreement with Peak
Energy, securing 1.5 gigawatt-hours of Peak Energy's U.S. manufactured
sodium-ion battery systems and secured exclusive regional channel rights
for Peak Energy's technology in the APAC region.
-- Closed $300 million preferred equity agreement with OIC for the launch
of new Own & Operate business called 'Asset Vault'; expected to
contribute $100-150 million in recurring Adjusted EBITDA by year-end
2029. Fund 1 now targets more than 1.5 GW of high-quality storage
projects across high-growth markets in the U.S., Australia, and Europe.
-- Completed acquisition of the 150 MW / 300 MWh SOSA Battery Energy
Storage System $(BESS)$ Project in Texas, marking the fourth project in the
Asset Vault portfolio.
-- Placed 8.5 MW / 293 MWh Calistoga Resiliency Center and 57 MW / 114 MWh
Cross Trails in service, collectively expected to contribute annualized
Adjusted EBITDA of $10 million.
-- Announced agreement with EU Green Energy to deploy up to 1.8 GWh of
BESS over the next four years, with a 400 MWh project in Albania, subject
to final legislative approval.
-- Demonstrated sustainability leadership once again, earning a 2025
Corporate Sustainability Assessment score of 74/100 from S&P Global
Sustainable and placing us in the 98th percentile of the Machinery and
Electrical Equipment industry.
-- Total megawatts now contracted, in operation and under construction
grew from 65 MW to 540 MW in the last 12 months across Asset Vault and
new AI Digital Infrastructure portfolio, and are expected to yield $150
million in annualized EBITDA, as projects come online over the next 18-36
months.
Business Outlook
-- Estimating full year 2026 revenue of $225-300 million (for 30% growth
year-over-year at the midpoint), reflecting the timing of U.S. battery
deliveries, third-party project timelines and full-year revenue from
operating assets within Asset Vault and initial contribution from modular
data center/AI infrastructure projects.
-- Expecting to complete project financing for the 150 MW / 300 MWh SOSA
project during 2Q 2026 and the 125 MW / 1 GWh Stoney Creek project in 2H
2026. Estimating $75-100 million in full year 2026 internal project
integration work related to the Asset Vault 'Own & Operate' portfolio,
which is expected to yield a 15% cash margin along with the
capitalization of associated labor. This contribution will not appear in
either consolidated GAAP Revenue or Gross Margin given the consolidation
of majority owned projects, but is expected to generate positive cash
flow in excess of Energy Vault's equity investment.
-- Estimating full year 2026 gross margin of 15-25% (versus 23.6% reported
for full year 2025).
-- Targeting $150-200 million in total cash at the end of 2026, including
net proceeds associated with our recently issued convertible notes,
project level financing and self-performed integration work associated
with Asset Vault projects under construction (namely the 150 MW SOSA
project in the U.S. and 12 5MW Stoney Creek project in Australia),
approximately $40 million in net ITC proceeds, customer receivables and
other growth initiatives.
-- Within Asset Vault, and including the recently awarded 100 MW / 870 MWh
EBOR project where the company maintains the exclusive option to acquire
(representing the fifth project under Asset Vault), we now has a line of
sight to approximately $60 million in recurring Adjusted EBITDA,
accelerating to $100-150 million in recurring Adjusted EBITDA by year end
2029.

Non-GAAP measures
Energy Vault has provided a reconciliation of net loss to adjusted EBITDA and adjusted Net Income, with GAAP Net Income 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 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.
Adjusted EBITDA is presented on a consolidated basis. Because our reconciliation starts with net loss attributable to Energy Vault Holdings, Inc., we add back net loss attributable to non-controlling interests to arrive at consolidated Adjusted EBITDA. Non-controlling interest allocations may be significantly impacted by the hypothetical liquidation at book value method to allocate Asset Vault's income (loss) between the Company and the redeemable non-controlling interest.
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.
