Energy Vault Prices $140 Million Convertible Senior Notes Offering

NRGV
February 12, 2026

Energy Vault Holdings, Inc. priced a $140 million aggregate principal amount of 5.250% convertible senior notes due 2031, an upsized offering from the originally announced $125 million. The private placement was completed to qualified institutional buyers and includes an option for initial purchasers to buy an additional $20 million within 13 days, with settlement expected on February 17, 2026.

The company will use the proceeds to fund capped‑call transactions, redeem $35‑45 million of existing convertible debentures, and support general corporate purposes. The capped‑call mechanism is designed to limit potential dilution if the notes are converted, while the redemption reduces the company’s existing debt burden and improves its balance‑sheet profile.

Energy Vault’s financials remain challenging. Trailing‑twelve‑month revenue stands at $83.84 million, unchanged over the past three years, and the company reports negative operating and net margins of –139.85% and –172.61%, respectively. An Altman Z‑Score of –1.77 places the company in the distress zone, underscoring the need for liquidity and debt‑management measures such as this offering.

Investors reacted negatively to the announcement, citing concerns that the convertible notes could increase share dilution and that the company’s weak financial position may limit its ability to generate sustainable earnings in the near term.

Management emphasized that the proceeds will strengthen the balance sheet and support ongoing projects, including the construction of the SOSA Energy Center in Texas and a long‑term energy‑service agreement for the Ebor project in Australia. The company remains cautious about achieving profitability, noting that full‑year 2025 adjusted EBITDA is still expected to be negative despite projected revenue growth to $200‑205 million and improving gross margins.

The financing provides a buffer while Energy Vault works toward profitability. Preliminary 2025 estimates show revenue growth and margin improvement, but the company’s financial challenges and the potential dilution from the convertible notes remain key considerations for stakeholders.
