Energy Vault Holdings expanded its recent convertible financing as initial purchasers exercised their option to buy an additional $10.0 million of 5.250% Convertible Senior Notes due 2031, bringing total notes issued to $150.0 million. These notes were sold in a private transaction exempt from Securities Act registration, and neither the notes nor the underlying common stock are registered for resale.
To hedge potential dilution from the extra notes, the company entered into additional capped call transactions covering the shares initially underlying the option notes. The capped calls are designed to reduce dilution or offset cash paid above principal on conversion, with a cap price initially set at $8.12 per share, a 100% premium to the $4.06 share price on February 11, 2026. The company also used part of the initial notes’ net proceeds to redeem $45.0 million of senior unsecured convertible debentures held by YA II PN, Ltd., simplifying its debt structure.

Energy Vault Holdings, Inc. completed a private offering of $140.0 million aggregate principal amount of 5.250% Convertible Senior Notes due 2031, which are unsecured and mature on March 1, 2031 unless earlier converted, redeemed, or repurchased.
The Notes pay 5.250% interest semiannually and are initially convertible at 193.1807 shares of common stock per $1,000 principal, implying an initial conversion price of about $5.1765 per share, a 27.5% premium to the $4.06 share price on February 11, 2026. The company can settle conversions in cash, stock, or both and may redeem the Notes for cash on or after March 5, 2029 if stock-price and liquidity conditions are met.
In connection with the pricing, the company entered into capped call transactions that cover the shares initially underlying the Notes, designed to reduce potential dilution or offset cash payments above principal, with an initial cap price of $8.12 per share, a 100% premium to the February 11, 2026 share price.
Energy Vault Holdings is raising capital through a private offering of $140.0 million aggregate principal amount of 5.250% convertible senior notes due 2031, sold to qualified institutional buyers. The offering was increased from a previously planned $125.0 million, and initial purchasers have an option for an additional $20.0 million of notes.
The notes mature on March 1, 2031, pay 5.250% interest semiannually, and are initially convertible at 193.1807 shares per $1,000 of notes, equal to a conversion price of about $5.18 per share, a 27.5% premium to the $4.06 stock price on February 11, 2026. Energy Vault expects net proceeds of about $135.5 million, or $154.8 million if the option is fully exercised.
The company plans to use the proceeds to pay for capped call transactions, redeem $35.0 million to $45.0 million of existing senior unsecured convertible debentures issued to YA II PN, Ltd., and for general corporate purposes, including potential additional debt repayment and funding growth initiatives. Capped call transactions, initially capped at $8.12 per share, are intended to reduce potential dilution or higher cash payments if the stock trades above the conversion price, though dilution can still occur above the cap.
