AI brief of an SEC Form 8-K · Energy Vault Holdings, Inc. (NRGV)

Energy Vault raises 2026 revenue guidance to $270-310 million; Q2 revenue up 104%

Positive Impact 4 of 5 guidance Written later

Energy Vault reported second-quarter 2026 revenue of $17.4 million, up 104% from a year earlier, and a GAAP net loss of $29.7 million, narrower than the $34.9 million loss in the prior-year quarter. The company raised its full-year 2026 revenue guidance to $270-310 million from $225-300 million and narrowed its GAAP gross margin guidance to 20-25% from 15-25%, which points to a stronger outlook for shareholders, though the company still reports losses and its adjusted EBITDA loss widened.

Key points

  • Q2 2026 revenue was $17.4 million, up from $8.5 million in Q2 2025, and GAAP gross margin was 31.0% versus 29.6%.
  • GAAP net loss was $29.7 million, or $(0.17) per share, compared with $34.9 million, or $(0.22) per share, a year earlier; adjusted EBITDA loss was $17.0 million versus $13.6 million.
  • Backlog reached about $2 billion as of August 10, 2026, up about 107% year over year, including a 1.25 GW contract expected to generate $500-600 million of revenue in the second half of 2026 and 2027.
  • Cash and cash equivalents, including restricted cash, were $148 million as of June 30, 2026; the company targets $160-200 million in total cash at year-end 2026.
