ESS Tech, Inc. Announces First Quarter 2024 Financial Results
Q1 Revenue of $2.7 Million
Partnered with Sapele Power to Supply LDES in Africa
Completed Testing of First Energy Center for Portland General Electric
Ordered Second Power Module Automation Line with 40% Greater Production Capacity
Exited Q1 with Cash and Short-Term Investments over $89 million; Expected to Carry ESS Well Into H1’25

WILSONVILLE, Ore. – May 7, 2024 – ESS Tech, Inc. (“ESS,” “ESS, Inc.” or the “Company”) (NYSE: GWH), a leading manufacturer of long-duration energy storage systems for commercial and utility-scale applications, today announced financial results for its first quarter ended March 31, 2024.
“I’m pleased with the team’s execution in the first quarter, where we again made tremendous progress across a broad number of fronts and achieved $2.7 million in revenue, a seven-fold increase over last year. Not only has our customer-facing team demonstrated marked success in commissioning products across a number of varied operating environments, but our sales team continues to win new deals and expand our footprint into new geographic markets with customers like Sapele Power, a leading African energy generation company. Momentum is growing behind our Energy Center™ (EC) product. We have completed all of our performance, safety and regulatory tests for our first EC and are operating the unit right now. We expect to start building and shipping our second unit early in Q3 and, given the significant energy density and cost per KWh advantages over our Energy Warehouse, we remain confident that our EC will be a key driver of long-term profitable expansion,” said Eric Dresselhuys, CEO of ESS. “Given the success of our first power module automation line, which has enabled us to increase capacity and consistency with dramatically lowered input costs, we’ve ordered our second power module automation line so that it becomes operational as we begin to ramp up shipments. With 40% more production capacity at half of the installed cost on a per MWh basis, our second line will greatly add to our momentum in lowering our production cost while enabling scale. With prudent cash management and efficient capacity expansion, our team continues to position the company for sustained growth and profitability as we scale the business and ramp up shipments later this year."
Recent Business Highlights
•EC products received the highest level of IEEE 693 rating, a widely-accepted seismic rating for energy infrastructure, making ESS the first non-lithium, grid-scale LDES provider to receive such a rating.
•Named as one of Fast Company’s 2024 Most Innovative Companies in the energy category.
•Named as a finalist for the Reuters 2024 Global Energy Transition Awards in “The Technologies of Change - Accelerating Decarbonization” category, which recognizes revolutionary technology in the energy sector.
•In addition to IEEE seismic certification, completed of all of the more than 90 tests to validate operations, safety and performance of our first Energy Center™. ESS will start building our second EC in the beginning of Q3, which will be deployed next to the first EC, both for Portland General Electric. We expect to start building and shipping our first commercial ECs in the second half of 2024 for delivery to Tampa Electric and the Sacramento Municipal Utility District, or SMUD.


•Ordered a second power module automation line, with the capability of producing more than 600 MWh per year, 40% more than the first automation line, which translates into substantially lower capex dollars per MWh of production capacity investment. This second line is expected to be operational in the 1H of 2025.
•Installed an Energy Warehouse™ system at Burbank Water and Power, their first utility-scale battery storage project. This EW is paired with an on-site solar array where ESS technology will demonstrate the critical role of LDES in a fully renewable grid.
•Completed commissioning of an Energy Warehouse™ (EW) system at Schiphol Airport in Amsterdam, the second largest airport in mainland Europe, which will be used to help advance Schiphol Airport’s sustainability strategy. The EW system will be used to recharge Electric Ground Power Units (E-GPU), which are intended to replace the diesel ground power units currently used to supply electrical power to aircraft when parked at the airport.

Use of Non-GAAP Financial Measures
In this press release and the accompanying earnings call, the Company includes Non-GAAP Operating Expenses and Adjusted EBITDA, which are non-GAAP performance measures that the Company uses to supplement its results presented in accordance with U.S. GAAP. As required by the rules of the Securities and Exchange Commission (“SEC”), the Company has provided herein a reconciliation of the non-GAAP financial measures contained in this press release and the accompanying earnings call to the most directly comparable measures under GAAP.

By providing these non-GAAP measures, the Company’s management intends to provide investors with a meaningful, consistent comparison of the Company’s profitability for the periods presented.

The Company defines and calculates Non-GAAP Operating Expenses as GAAP Operating Expenses adjusted for stock-based compensation and other special items determined by management as they are not indicative of business


operations. The Company defines and calculates Adjusted EBITDA as net loss before interest, other non-operating expense or income, (benefit) provision for income taxes, and depreciation and amortization, and further adjusted for stock-based compensation and other special items determined by management, including, but not limited to, fair value adjustments for certain financial liabilities associated with debt and equity transactions as they are not indicative of business operations.
