Energy Vault Holdings, Inc. (NRGV), a provider of energy storage solutions, saw its stock price soar 8.73% in pre-market trading on Tuesday. This surge follows a robust 10.99% gain during Monday's trading session, as investors continue to react positively to the company's recent earnings report and strategic developments.

Despite reporting third-quarter revenue that fell short of analyst expectations, Energy Vault has managed to maintain investor confidence. The company's Q3 2025 revenue came in at $33.32 million, missing the consensus estimate of $49 million but still representing a remarkable 27-fold increase year-over-year. Importantly, Energy Vault reaffirmed its full-year 2025 guidance, projecting revenue between $200-250 million and a gross margin of 14-16%. This optimistic outlook, combined with a narrowing adjusted EBITDA loss, seems to be outweighing concerns about the Q3 revenue miss.

Adding to the positive sentiment, Energy Vault recently closed a $300 million preferred equity agreement for its Asset Vault business, potentially strengthening its financial position and growth prospects. The company also aims to have $75-100 million in total cash by the end of 2025, further solidifying its financial standing. These strategic moves, along with the company's strong year-over-year growth and maintained guidance, appear to be driving the continued stock price surge in pre-market trading, as investors focus on Energy Vault's long-term potential in the growing energy storage market.
