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 fourth quarter and full-year ended December 31, 2022.

Robert Piconi, Chairman and CEO of Energy Vault, stated, “Our strong execution in Q4 ahead of plan capped off a highly transformative year for Energy Vault in 2022 as we concluded our first year as a public company and executed a differentiated solutions-focused approach to win large contracts and begin deployment with top utilities and global independent power producers. I was most impressed with the resiliency and customer focus of our people, and specifically the velocity of our technology development which supported key commercial wins with market leading public utilities and IPPs. This clearly demonstrated the market validation of our strategy and highlights our unique capability to deliver short, long and ultra-long duration storage solutions.”

Mr. Piconi concluded, “Looking ahead to 2023, we are well positioned and poised to take advantage of the industry growth tailwinds for energy storage globally, and specific growth and economic accelerators in the U.S. market driven by the passage of the IRA. Compounding this positive impact specific to Energy Vault is our portfolio of proprietary storage solutions that can uniquely take advantage of incentives related to US domestic content and integration and manufacturing that we can monetize with ITC and/or Advanced Manufacturing Credit with our gravity and hybrid green hydrogen storage solutions. As the Treasury department releases actual rule mechanics, we will be ensuring we maximize the benefits of this legislation which would represent upsides to our current 2023 outlook. Beyond the IRA in the USA, we are beginning to see other regions of the world potentially implement similar legislation to maintain their regional competitiveness.”

2023 Outlook:

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

Robert Piconi, Chairman and CEO of Energy Vault, stated, “As we guide on expected 2023 financial performance, relative to revenue, the range of $325 to $425 million reflects adjustments to our prior forecast due in part to the accelerated revenue recognized earlier than planned in Q4 2022 but was primarily due to the shift in the contracting strategy on ~ 1GWh of projects where Energy Vault remains the integrator of choice while the customer is procuring the battery modules directly. While this results in lower revenue, it will enable us to expand the total number of projects with customers and realize higher percentage gross margins on these projects in line with our focus on double-digit unit economics and reducing supply chain, execution risk and working capital exposure. Finally, given the magnitude of the second half 2023 revenue recognition ramp where Energy Vault is concurrently turning over three of its initial energy storage projects while planning for multiple new projects starts, we have taken a more measured approach to allow for any potential customer-driven delays in Q4 in particular.

Underpinning the specific items noted above, we have built in a level of conservatism on the low end of the range as we plan for an uncertain macro environment and any unforeseen supply chain, labor and geopolitical issues outside of our control. We will continue to focus on large projects where we uniquely add value in hardware and software design and thus can achieve higher levels of profitability – in some instances, this will include allowing customers to self-source low-margin or pass through equipment while we focus on value-added services that may result in lower total revenue but higher gross margins. Third, we will continue to prudently focus on managing our operating expenses. While revenue will be growing from two to three times 2022 levels, we are holding our operating expense flat from our Q4 2022 annualized run rate. Lastly, investors can expect an aggressive quarterly 2023 revenue ramp starting from low double-digit revenues in Q1 to high double-digit revenue in Q2 and into triple digit revenue in the second half of the year.

We have a clear line of sight to achievability of this revenue range due to our contracted revenue already under execution with planned commercial operation dates in the second half of 2023. We are also looking at further upside from pending gravity licenses, additional territory expansions, and incremental projects leading to potential for second half 2023 revenue recognition.”

Jan Kees van Gaalen, CFO of Energy Vault, stated, “I am thrilled to be part of supporting Energy Vault’s execution and profitability priorities during this exciting growth phase as the company scales its global presence.”

Fourth Quarter 2022 and Recent Business Highlights:

• Global Gravity technology expansion through royalty and licensing agreements in Europe and the Middle East: The initial 10-year terms enable the exclusive use of the licensed technology including the EVx and related software as well as additional construction and technology support. The agreements include a recurring revenue stream related to the deployment and operation of the EVx system in the territory.
• PG&E teams with Energy Vault to build and operate one of the largest green hydrogen long-duration energy storage system in the U.S.: we expect the hybrid system to be capable of powering approximately 2,000 electric 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 one of 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 with construction anticipated to begin in Q4 2023 and commercial operation expected by the end of Q2 2024.
• NV Energy and Energy Vault partner for 440 MWh energy storage system in Nevada: Energy Vault to work with Nevada’s largest public electric utility to deploy a 220MW/440MWh battery energy storage solution (BESS). The BESS, one of the largest in Nevada, is expected to start construction in Q2 2023 with commercial operation expected by the end of 2023.
• Awarded a 250 MW/500 MWh grid-connected battery storage agreement in Victoria, Australia: Meadow Creek Solar pty Ltd., a developer of the Meadow Creek Solar Farm has awarded Energy Vault a 250 MW/500 MWh BESS project to support its 330 MW solar project. Under the notice of the award, Energy Vault has begun the advanced grid studies and modeling with technical advisor DNV, as required by the Australian Energy Market Operator (AEMO) for interconnected power systems in Australia's eastern and south-eastern seaboard, which will be located 2 hours north of Melbourne, Australia. The battery energy storage solution, being co-located with the solar PV, is expected to provide the flexibility of charge and discharge, essential to shoring up renewable energy supply across the network as Australia adopts the Australian Energy Market Operator's Integrated System Plan. The project is expected to be completed in 2024.
• Announced Theresa Fariello has joined the Board of Directors: Ms. Fariello has served as Senior Vice President of Government Affairs & Global Public Policy for United Airlines (Nasdaq: UAL) since 2017. In this role, she leads United Airlines’ federal, state, local, and international government engagement, including environmental affairs. Throughout her career, Ms. Fariello has been recognized for her success and leadership in government, including being named to Washingtonian Magazine’s list of Most Powerful Women.

Non- GAAP measures

Energy Vault has provided a reconciliation of Adjusted EBITDA to net loss, the most directly comparable GAAP measures, for the historical period in the appendix hereto. A reconciliation of projected non-GAAP measures for the full-year 2022 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 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 GAAP net loss as an indicator of our performance.

The following table provides a reconciliation from non-GAAP adjusted EBITDA to GAAP net loss, 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.
