Rhea-AI Filing Summary

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.

Insights

Energy Vault raises $140M via 5.25% converts, refinancing some debt and adding capped calls.

Energy Vault is issuing $140.0 million of 5.250% convertible senior notes due 2031, upsized from $125.0 million, with an option for another $20.0 million. The estimated net proceeds of $135.5 million (or $154.8 million with the option) add long-dated capital at a fixed coupon.

The initial conversion price of about $5.18 per share, a 27.5% premium to the $4.06 stock price on February 11, 2026, implies potential future equity issuance if the stock trades above that level. Planned redemption of $35.0 million to $45.0 million of existing convertible debentures to YA II PN, Ltd. partially refinances the capital structure.

Capped call transactions, initially capped at $8.12 per share (a 100% premium to $4.06), are designed to mitigate dilution or excess cash outlay upon conversion up to the cap. Above the cap price, the company notes that dilution or unhedged cash obligations could still occur, so the ultimate impact depends on future share prices and conversion behavior.

Energy Vault Announces Upsize and Pricing of $140 Million Convertible Senior Notes Offering

 

WESTLAKE VILLAGE, Calif., February 11, 2026 - Energy Vault Holdings, Inc. (NYSE: NRGV) (“Energy Vault”), a leader in sustainable, grid-scale energy storage solutions, today announced the pricing of $140.0 million aggregate principal amount of 5.250% convertible senior notes due 2031 (the “Notes”) in a private placement to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”). The offering was upsized from the previously announced offering size of $125.0 million aggregate principal amount of Notes. Energy Vault also granted the initial purchasers of the Notes an option to purchase, for settlement within a 13-day period, beginning on, and including, the date on which the Notes are first issued, up to an additional $20.0 million aggregate principal amount of the Notes. The sale of the Notes to the initial purchasers is expected to settle on February 17, 2026, subject to customary closing conditions, and Energy Vault estimates that it will receive approximately $135.5 million in net proceeds (or $154.8 million if the initial purchasers exercise their option to purchase additional Notes in full) before deducting fees and estimated expenses payable by Energy Vault.

 

The Notes

 

The Notes will bear interest at a rate of 5.250% per year. Interest will be payable semiannually in arrears on March 1 and September 1 of each year, beginning on September 1, 2026. The Notes will mature on March 1, 2031, unless earlier converted, redeemed or repurchased in accordance with their terms. Energy Vault may not redeem the Notes prior to March 5, 2029. Energy Vault may redeem for cash all or part of the Notes, at its option, on or after March 5, 2029, if the last reported sale price of the Company’s common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which Energy Vault provides notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. Following certain corporate events that occur prior to the maturity date or if the Company delivers a notice of redemption with respect to all or a part of the Notes, the Company will, in certain circumstances, increase the conversion rate for noteholders who elect to convert their Notes in connection with such corporate event or notice of redemption.

 

The initial conversion rate for the Notes is 193.1807 shares of the Company’s common stock per $1,000 principal amount of the Notes (which is equivalent to an initial conversion price of approximately $5.18 per share of the Company’s common stock). The initial conversion price represents a premium of approximately 27.5% over the last reported sale price of the Company’s common stock on the New York Stock Exchange of $4.06 per share on February 11, 2026. Upon conversion, the Notes will be settled in cash, shares of the Company’s common stock or a combination thereof, at the Company’s election.

 

 

 

 

The Company expects to use the net proceeds from the offering to fund the cost of entering into capped call transactions described below, redeem $35.0 million to $45.0 million in aggregate principal amount of the senior unsecured convertible debentures issued to YA II PN, Ltd., and the remainder for general corporate purposes, which may include, among other things, the repayment of additional indebtedness and funding growth initiatives. If the initial purchasers exercise their option to purchase additional Notes, the Company expects to use the net proceeds from the sale of the additional Notes to enter into additional capped call transactions with the option counterparties and the remainder for general corporate purposes.

 

Capped Call Transactions

 

In connection with the pricing of the Notes, Energy Vault entered into privately negotiated capped call transactions with certain of the initial purchasers or their affiliates and another financial institution (the “option counterparties”). The capped call transactions will cover, subject to customary adjustments, the number of shares of Energy Vault’s common stock initially underlying the Notes. If the initial purchasers exercise their option to purchase additional Notes, then Energy Vault expects to enter into additional capped call transactions with the option counterparties, and will use a portion of the additional net proceeds to fund the cost of such additional capped call transactions (and the remainder for the same purposes as described above).

 

The cap price of the capped call transactions will initially be $8.12 per share, which represents a premium of 100% over the last reported sale price of the Company’s common stock on the New York Stock Exchange of $4.06 per share on February 11, 2026, and is subject to certain adjustments under the terms of the capped call transactions.

 

The capped call transactions are expected generally to reduce a potential dilution to Energy Vault’s common stock upon any conversion of the Notes and/or offset any cash payments Energy Vault is required to make in excess of the principal amount of converted Notes, as the case may be, in the event that the market price per share of our common stock, as measured under the terms of the capped call transactions, is greater than the strike price of the capped call transactions, which initially corresponds to the conversion price of the notes and is subject to customary anti-dilution adjustments. If, however, the market price per share of Energy Vault’s common stock, as measured under the terms of the capped call transactions, exceeds the cap price of the capped call transactions, there would nevertheless be dilution and/or there would not be an offset of such potential cash payments, in each case, to the extent that such market price exceeds the cap price of the capped call transactions.

 

In connection with establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates expect to enter into various derivative transactions with respect to Energy Vault’s common stock and/or purchase shares of Energy Vault’s common stock concurrently with or shortly after the pricing of the Notes. This activity could increase (or reduce the size of any decrease in) the market price of Energy Vault’s common stock or the Notes at that time.

 

In addition, the option counterparties and/or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with respect to Energy Vault’s common stock and/or purchasing or selling Energy Vault’s common stock or other securities of Energy Vault in secondary market transactions following the pricing of the Notes and prior to the maturity of the Notes (and are likely to do so (x) during the 60 trading day period beginning on the 61st scheduled trading day prior to the maturity date of the Notes or (y) to the extent Energy Vault exercises the relevant termination election under the capped call transactions, following any repurchase, redemption or conversion of the Notes). This activity could also cause or avoid an increase or a decrease in the market price of Energy Vault’s common stock or the Notes, which could affect the ability of noteholders to convert the Notes and, to the extent the activity occurs during any observation period related to a conversion of Notes, it could affect the number of shares of common stock, if any, and value of the consideration that noteholders will receive upon conversion of the Notes.
