Long-duration energy storage and gravity infrastructure pioneer Energy Vault Holdings, Inc. announced its financial and operational results for the third quarter ended September 30, 2026, on Tuesday, November 10, 2026. The corporate filing revealed that commercial contracted and option project backlog expanded to $2.3 billion, representing an impressive 147 percent year-over-year increase compared to $930 million recorded in the prior-year period. Energy Vault reaffirmed its full-year 2026 revenue guidance while issuing preliminary revenue projections for fiscal year 2027 exceeding $600 million.
Q3 revenue of $13.1 million and 2027 targets
Global utility-scale demand for multi-hour energy shifting drove substantial commercial expansion across grid-scale energy portfolios. Project execution advanced. Energy Vault's $2.3 billion backlog comprises roughly $800 million in Build and Transfer engineering contracts alongside $1.5 billion in recurring Build, Own & Operate assets. Third-quarter recognized revenue totaled $13.1 million, aligning with delivery timelines. Concurrently, adjusted gross margin reached 81.1 percent, supported by the formal collection of $4.3 million in retroactive equipment tariff refunds.
Speaking during Tuesday afternoon's investor conference call, Energy Vault Chief Executive Officer Robert Piconi detailed operational achievements. The executive stated: "Expanding our commercial backlog to $2.3 billion, reflecting 147 percent annual growth, confirms the escalating global demand for our hybrid energy storage architectures. The robust execution of our engineering teams provides revenue visibility spanning multiple fiscal years. We remain focused on commissioning utility-scale deployments on schedule throughout the fourth quarter."
Supported by project construction schedules, executive leadership reaffirmed that full-year 2026 consolidated revenue will achieve the upper half of its previously raised $290 million to $310 million guidance band. Full-year gross margins are expected to average between 20 percent and 22 percent. Furthermore, management introduced preliminary financial targets for fiscal year 2027, projecting gross revenues between $600 million and $700 million alongside adjusted EBITDA of $40 million to $50 million.
Analysts react to backlog and cash outlook
Wall Street equity analysts covering energy transition technologies reacted favorably to the backlog expansion. In an equity research brief distributed to institutional investors, a clean technology research director observed: "In an increasingly competitive energy storage landscape, Energy Vault has successfully diversified beyond mechanical gravity systems into integrated battery software architectures. Massive forward backlog figures validate commercial traction across major utility accounts."
The company projects year-end cash balances to remain between $170 million and $200 million, supporting ongoing project capitalization across North America and Australia.
In addition, electrical transmission engineers and grid reliability researchers observed that multi-hour storage infrastructure serves as an indispensable stabilizing asset for regional balancing authorities. By absorbing excess renewable power during midday peak generation and reinjecting electricity during evening peak intervals, hybrid storage configurations effectively resolve transmission bottleneck challenges across modern decarbonized electrical grids.
Grid reliability and institutional collaboration outlook
