LUGANO, Switzerland & WESTLAKE VILLAGE, Calif. / May 09, 2023 / 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 first quarter ended March 31, 2023.

Robert Piconi, Chairman and CEO of Energy Vault, stated, “Following robust quarterly revenues of over $100 million in the fourth quarter of 2022, we had a strong commercial start to the year with impressive near term funnel growth dynamics and project awards of ~$1 billion while continuing our customer focus in executing on ~1 GWh of US battery projects on track for COD in the second half of 2023. We continue to make strong progress on our diverse range of projects, including the first deployment of the Company’s EVx gravity energy storage system (GESS) in China. During my recent trip to Rudong and Beijing in April, I had the opportunity to visit the site and witness the progress being made. We expect mechanical completion in Q2 2023 as previously anticipated and commencement of commissioning activities immediately afterwards.”

Mr. Piconi continued, “Looking ahead, we are laser focused on profitable and timely execution on our project portfolio to meet or exceed all customer requirements. I continue to be impressed with our team’s passion to serve our customers well. This is creating strong current customer references while also enabling additional project discussions to support our existing customer growth plans. This is underpinned by our technology-agnostic software platform and experienced team that can uniquely design solutions across short, long and ultra-long duration energy storage as the recent multi-day green hydrogen hybrid storage solution for PG&E demonstrates. Finally, we are optimistic about the magnitude of potential financial benefits from the Inflation Reduction Act (IRA) and the positive impact they can have to our existing forecast, in particular with our owned projects and what we have announced today with our investment into domestic US content battery supply chains. Overall, there are numerous tailwinds that reinforce my enthusiasm for our current position and our ability to drive long-term shareholder value.”

First Quarter 2023 and Recent Business Highlights:

• Energy Vault and PG&E receive CPUC approval for Calistoga microgrid project: The California Public Utilities Commission (CPUC) has approved the request from Pacific Gas and Electric Company (PG&E), a subsidiary of PG&E Corporation (NYSE: PCG), for Energy Vault to deploy and operate a utility-scale battery plus green hydrogen long-duration energy storage system (BH-ESS). We expect the hybrid system to be capable of powering approximately 2,000 electricity customers within PG&E’s Calistoga microgrid for up to 96 hours (700 MWh of carbon-free energy) during a planned outage. This long-duration energy storage system is the “first-of-its-kind” and integrates a short duration battery system (for grid forming and black start capabilities) with a long duration liquid hydrogen-powered fuel cell system. The system is managed and dispatched by Energy Vault’s technology-agnostic Energy Management Software (EMS) to optimize performance and safety while minimizing operational cost. Further, the project is supported by a 10.5-year tolling agreement.
• Executed a strategic investment in Kore Power, a US manufacturer of batteries cells and modules, to build supply continuity on a prioritized basis for domestic US content supply chains for Energy Vault’s US customers, supporting our short duration battery energy storage solutions on a preferred economic basis. In parallel with Energy Vault’s investment, we also executed a comprehensive battery supply agreement. This agreement will significantly benefit our domestic customers as envisioned with their IRA project eligibility. In Q4 2022, Energy Vault participated in the initial tranche as an undisclosed investor alongside Siemens Financial Services, Quanta Services, Honeywell Ventures and others. In Q1 2023 we made our second and final strategic investment.
• Expanded previously announced Jupiter Power partnership to supply domestic US content of electrochemical battery modules from 2.4 GWh to 10 GWh, further strengthening the relationship with Jupiter to ensure supply chain priority on a 2-5 year planning horizon of project development while maximizing the financial benefits from the current IRA legislation.
• On track for commercial deployment of all three of the battery energy storage systems (BESS) within customer stated COD dates: Our initial project with Wellhead Electric (275 MWh) is expected to be completed in Q3 2023. Subsequently, Jupiter Power (220 MWh) and NV Energy (440 MWh) projects are anticipated to be installed before the end of the year.

2023 Outlook:

Energy Vault is reiterating its previously announced 2023 financial outlook, including:

• Energy Vault expects total revenue to be in the range of $325 million to $425 million, which reflects growth of approximately 2x to 3x over 2022.
• Gross margin in the 10-15% range.
• Adjusted EBITDA for the full-year 2023 is expected to be in the range of $(50) million to $(70) million.

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. A reconciliation of projected non-GAAP measures for the full-year 2023 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.

Non-GAAP Financial Measure

We use adjusted EBITDA to complement our condensed consolidated statements of operations. Management believes that this non-GAAP financial measure complements our GAAP net loss and such measure is useful to investors. The presentation of this non-GAAP measure is not meant to be considered in isolation or as an alternative to net loss as an indicator of our performance.

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 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 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.
