Exclusive $300M Investment Ignites Energy Vault’s Bullish Momentum
Energy Vault’s 23.5% surge stems from its exclusivity agreement for a $300M preferred equity investment to launch Asset Vault, a fully consolidated subsidiary. This non-dilutive funding accelerates the deployment of 1.5GW of energy storage projects across the U.S., Australia, and Europe, with clear monetization via long-term contracts and ITC incentives. The deal also aligns shareholder interests through equity participation milestones and projects $100M+ in recurring EBITDA within 3-4 years. CEO Robert Piconi emphasized the strategic use of capital to leverage Energy Vault’s EPC capabilities, enhancing margins and liquidity for the parent company.

Backtest Energy Vault Stock Performance
The 24% intraday surge in NRGV resulted in mixed short-to-medium-term performance. While the 3-day win rate was 46.76%, indicating a majority of days with positive returns in the initial period, the 10-day and 30-day win rates were lower at 47.45% and 48.84%, respectively. This suggests that while NRGV showed promise in the immediate aftermath of the surge, its performance cooled off over longer time frames. The maximum return during the backtest period was 0.41%, which occurred on day 5, indicating that the best performance was relatively modest and not sustained.
