Energy Vault Holdings, Inc. (NRGV) continued its upward trajectory with an 8.73% pre-market soar on Tuesday, following a robust 10.99% gain in Monday's trading session. The company's stock is experiencing significant momentum despite reporting mixed third-quarter results, as investors focus on its reaffirmed full-year guidance and recent strategic developments.

Although Energy Vault's Q3 2025 revenue of $33.32 million fell short of analyst expectations, the figure represents a remarkable 27-fold increase year-over-year. The company also showed improvements in other areas, with its adjusted EBITDA loss narrowing by 59% to $6.0 million. Importantly, Energy Vault reaffirmed its full-year 2025 guidance, estimating revenue between $200-250 million and a gross margin of 14-16%, which appears to be bolstering investor confidence.

The continued stock surge is further supported by Energy Vault's recent strategic moves, including the closure of a $300 million preferred equity agreement for its Asset Vault business. This development, along with the company's target of $75-100 million in total cash by the end of 2025, suggests a strengthening financial position and improved growth prospects. As the market digests these positive factors, Energy Vault's stock continues to attract investor interest, driving the pre-market rally.
