WESTLAKE VILLAGE, Calif. / Nov 12, 2024 / 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, 2024.

“We made good progress in the quarter building our contracted revenue backlog by 33% while at the same time increasing our longer-term development pipeline of storage infrastructure projects in the U.S. and Australia with long-term offtake agreements,” said Robert Piconi, Chairman and CEO of Energy Vault. “With the first and largest green hydrogen storage microgrid project with PG&E in Calistoga, CA nearing completion, and the recently announced 10-year offtake agreement in place for the Cross Trails BESS project in Snyder, Texas, we are taking large steps in delivering innovative storage solutions while executing our strategy to build, own and operate storage assets that we believe will create accretive, predictable and highly profitable cash flow streams over the long term. The Energy Vault Team is building strong momentum in new product innovations and global pipeline development as we close 2024.”

Financial Highlights

• Current revenue backlog of $350 million (increased 33% quarter-over-quarter), reflects the addition of a 100MW / 200MWh BESS project with Jupiter, and signed offtake agreement with Gridmatic for the 57MW / 114MWh Cross Trails BESS project as part of our ‘Build, Own and Operate Strategy’
• Current developed pipeline of shortlisted and awarded projects improved 11% quarter-over-quarter to 10.8 GWh, remaining stable at $2.7 billion, adjusted for prevailing market prices and foreign exchange rates
• With construction of BESS projects in Texas and Nevada now complete, the Company reported software and services-related revenue of $1.2 million in the third quarter.
• Third quarter 2024 GAAP gross margin of 40.3% and gross profit of $0.5 million, driven by higher margin software and service revenue
• Operating expense improved to $27.6 million in Q3 2024; Adjusted operating expense of $15.2 million, improved 13% year-over-year and 7% quarter-over-quarter following the organizational realignment in first half of 2024
• GAAP net loss of $(26.6) million during the quarter reflecting the lower quarterly revenue recognition, partially offset by lower operating expenses versus prior quarter and prior year.
• Adjusted EBITDA improved $0.7 million or 5% quarter-over-quarter to $(14.7) million from $(15.4) million despite minimal revenue recognition due to lower cash operating expenses following the organizational realignment in first half of 2024
• Total cash and cash equivalents of $77.7 million and no debt on the balance sheet as of September 30, 2024. The company reported $48.3 million in use of cash from investing activities, mainly construction in progress on owned projects year-to date, which we expect to be offset with project financing and monetization of IRA-related tax credits over the next two quarters
• Initial contribution from new BESS projects with Jupiter in Texas and ACEN in Australia to near-term revenue and gross profit
• Strong pipeline of storage asset ownership opportunities and infrastructure projects in the U.S. and Australia totaling 30GWh+, expected to deliver long-term project EBITDA margins of 70-80%
• Energy Vault expects full-year 2024 guidance for Revenue, Gross Margin, Adjusted EBITDA and year-end cash to be within the mid to low end of the previously provided guidance ranges. The latest outlook reflects the timing of equipment deliveries and associated revenue recognition in the fourth quarter of 2024, as well as timing of cash receipts for project financing and returns of working capital. As part of the Company’s ‘Build, Own & Operate Strategy’ announced earlier this year, management expects to retain ownership of approximately $100 million in storage assets rather than generate revenue through the sale of those projects in 2024, as previously guided.

Operating and Other Highlights

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 unavailable 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 reflects uncontracted, potential revenue, from projects in which potential prospective customers have either awarded a project to the Company, or have put the Company on a shortlist to be awarded a project.

Backlog reflects contracted but unrecognized revenue from projects and services yet to be completed, unrecognized revenue or other income from intellectual property licensing agreements, and unrecognized revenue from tolling arrangements

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, 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.

Effective September 30, 2024, the Company has included provision (benefit) for credit losses as a non-GAAP adjustment because management does not consider this item in assessing our ongoing performance. Prior periods have been adjusted to include provision (benefit) for credit losses as a non-GAAP adjustment.

The following table provides a reconciliation from GAAP S&M expenses to non-GAAP adjusted S&M expenses (amounts in thousands):

The following table provides a reconciliation from GAAP R&D expenses to non-GAAP adjusted R&D expenses (amounts in thousands):

The following table provides a reconciliation from GAAP G&A expenses to non-GAAP adjusted G&A expenses (amounts in thousands):

The following table provides a reconciliation from GAAP operating expenses to non-GAAP operating expenses (amounts in thousands):

The following table provides a reconciliation from net loss to non-GAAP adjusted EBITDA, with net loss being the most directly comparable GAAP measure (amounts in thousands):

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 adjusted EBITDA measure excludes the financial impact of items management does not consider in assessing our ongoing operating performance, and thereby facilitates review of our operating performance on a period-to-period basis.

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 condensed 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.
