Item 1.01 Entry into a Material Definitive Agreement.

Amendment to AR Convertible Debentures Securities Purchase Agreement

As previously disclosed, on May 18, 2026, Energy Vault Holdings, Inc. (the “Company”) entered into a Securities Purchase Agreement (the “Purchase Agreement”) with YA II PN, Ltd. (the “Investor”), pursuant to which the Company agreed to issue and sell senior secured convertible debentures in multiple tranches with an aggregate principal amount of up to $75.0 million and an initial tranche of $42.0 million funded at closing (the “Tranche 1 AR Convertible Debenture”). The size and availability of the facility is determined and supported by the Company’s current contracted backlog and third-party commercial activity.

Due to a material increase in the Company’s commercial backlog since the previously issued Quarterly Report for the quarter ended March 31, 2026 (please see Item 7.01 to this Current Report on Form 8-K for additional information), on June 29, 2026, the Company and the Investor entered into the first amendment to the Purchase Agreement (the “First Amendment”), pursuant to which the Company agreed to issue and sell an additional $38.0 million of senior secured convertible debentures to the Investor at a purchase price equal to 95% of such additional principal amount. In connection with the foregoing, the Company amended and restated the Tranche 1 AR Convertible Debenture (as amended and restated, the “Amended and Restated AR Convertible Debenture”) to give effect to the increased aggregate principal amount of $80.0 million.

The Amended and Restated AR Convertible Debenture continues to bear interest at a rate of 7.50% per annum, increased the monthly installment amounts correspondingly and extended the maturity date from May 17, 2027 to July 1, 2027. The Amended and Restated AR Convertible Debenture is convertible into shares of the Company’s common stock at a conversion price equal to 97% of the lowest daily volume-weighted average price of the common stock during the four consecutive trading days immediately preceding the applicable conversion date, subject to a floor price of $1.19 per share. The Amended and Restated AR Convertible Debenture also provides that the $4.22 million in principal amount plus all accrued and unpaid interest in respect of such amount of the December 29, 2026 installment may be converted by the Investor in accordance with the conditions set forth in the Amended and Restated AR Convertible Debenture. The Company may not issue shares of common stock upon conversion to the extent such issuance would exceed 19.99% of the Company’s outstanding common stock as of closing, unless stockholder approval to exceed such cap is obtained in accordance with the rules and regulations of the NYSE (the “Exchange Cap”). Pursuant to the Exchange Cap, the Amended and Restated AR Convertible Debenture is convertible for a maximum of 33,251,333 shares of common stock. The additional tranche was funded at closing on June 29, 2026. Net proceeds are expected to be approximately $34.6 million after deductions for an original issue discount of 5% and a structuring fee of $1.25 million. The Company and Investor also mutually agreed to increase the aggregate principal amount issuable under the Purchase Agreement to $150.0 million.

The foregoing descriptions of the First Amendment and the form of Amended and Restated AR Convertible Debenture are qualified in their entirety by reference to the full text of the First Amendment and the form of Amended and Restated AR Convertible Debenture, which are attached as Exhibit 10.1 and Exhibit 4.1, respectively, to this Current Report on Form 8-K and incorporated herein by reference.

Consent, Waiver and Amendment to CRC Note Purchase Agreement

As previously disclosed, on April 4, 2025, Calistoga Resiliency Center, LLC (“CRC”), a wholly-owned subsidiary of the Company, entered into a Note Purchase Agreement, as amended by Amendment No. 1 thereto, dated as of August 4, 2025 (the “CRC Note Purchase Agreement”), with Eagle Point Credit Management, LLC, pursuant to which CRC issued $27.8 million in aggregate principal amount of senior secured notes (the “CRC Senior Notes”). Capitalized terms used herein and not otherwise defined have the meanings ascribed to them in the CRC Note Purchase Agreement.

On June 26, 2026, CRC, the holders party thereto, and Wilmington Trust, National Association, as collateral agent, entered into the Consent, Waiver and Amendment No. 2 to the CRC Note Purchase Agreement (the “CRC Amendment”). Pursuant to the CRC Amendment, the holders (i) consented to a voluntary prepayment of the CRC Senior Notes in an aggregate principal amount of approximately $5.0 million, (ii) waived the make-whole amount and related certificate delivery requirements otherwise applicable to such prepayment, (iii) consented to the release, withdrawal and transfer of excess reserve amounts for application to such prepayment and (iv) deferred the testing date for the Debt Service Coverage Ratio covenant to November 30, 2026.

The foregoing description of the CRC Amendment is qualified in its entirety by reference to the full text of the CRC Amendment, which is attached as Exhibit 10.2 to this Current Report on Form 8-K and incorporated herein by reference.

Consent and Waiver to Cross Trails Credit Agreement

As previously disclosed, on July 23, 2025, Cross Trails Energy Storage Project, LLC (the “Cross Trails”), a subsidiary of the Company, entered into a credit agreement (the “Cross Trails Credit Agreement”) with Wilmington Trust, National Association, as administrative agent and collateral agent, and each of the lenders party thereto. Capitalized terms used herein and not otherwise defined have the meanings ascribed to them in the Cross Trails Credit Agreement.

On June 29, 2026, Cross Trails entered into the Consent and Waiver to the Cross Trails Credit Agreement (the “Cross Trails Consent”) with Wilmington Trust, National Association, as administrative agent and collateral agent, and the lenders party thereto. Pursuant to the Cross Trails Consent, the lenders (i) consented to certain modifications to the methodology for calculating the debt service coverage ratios under the Cross Trails Credit Agreement for each fiscal quarter beginning on March 31, 2026 and ending on December 31, 2027, (ii) reduced the minimum Historical Debt Service Coverage Ratio and the minimum Pro Forma Debt Service Coverage Ratio, and (iii) waived any default under the Cross Trails Credit Agreement arising from Cross Trails’ failure to comply with the debt service coverage ratio requirements for the fiscal quarters ending on March 31, 2026 and June 30, 2026.

The foregoing description of the Cross Trails Consent is qualified in its entirety by reference to the full text of the Cross Trails Consent, which is attached as Exhibit 10.3 to this Current Report on Form 8-K and incorporated herein by reference.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information contained in Item 1.01 with respect to the Amended and Restated AR Convertible Debenture, the CRC Amendment and the Cross Trails Consent is incorporated herein by reference.

Item 3.02 Unregistered Sales of Equity Securities.

The disclosure set forth above in Item 1.01 relating to the issuance of any shares to be issued in connection with a conversion of some or all of the Amended and Restated AR Convertible Debenture and relating to the issuance of the Amended and Restated AR Convertible Debenture, is incorporated by reference herein in its entirety.

The issuance of the Amended and Restated AR Convertible Debenture pursuant to the First Amendment was made in reliance upon the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933. This Current Report on Form 8-K shall not constitute an offer to sell or the solicitation of any offer to buy the securities discussed herein, nor shall there be any offer, solicitation, or sale of the securities in any state in which such offer, solicitation, or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

Item 7.01 Regulation FD Disclosure.

The Company’s sales backlog increased materially from $1.3 billion as of March 31, 2026. See the Company’s Quarterly Report for the quarter ended March 31, 2026 filed with the Securities and Exchange Commission on May 19, 2026 for the definition and additional information regarding determination of the Company’s backlog.

The Company cannot guarantee that its bookings will result in actual revenue in the originally anticipated period, or at all. The Company’s customers may experience project delays or cancel orders as a result of external market factors and economic or other factors beyond our control. Many of the Company’s projects require government approvals, third-party financing, and other contingencies, many of which are beyond its control. If the Company’s bookings fail to result in revenue as anticipated or in a timely manner, the Company could experience a reduction in revenue, profitability, and liquidity. See “Risk Factors - Our total backlog, bookings, and developed pipeline may not be indicative of our future revenue, which could have a material impact on our business, financial condition, and results of operations” in the Company’s Annual Report for the year ended December 31, 2025 filed with the Securities and Exchange Commission on March 18, 2026.

FOR VALUE RECEIVED, ENERGY VAULT HOLDINGS, INC., an entity organized under the laws of Delaware (the “Company”), hereby promises to pay to YA II PN, LTD., or its registered assigns (the “Holder”) the amount set out above as Outstanding Principal Amount (or such lesser amount as reduced pursuant to the terms hereof pursuant to repayment, redemption, conversion or otherwise, the “Principal”), in each case when due, and to pay interest (“Interest”) on any outstanding Principal at the Interest Rate (as defined below) from and including the date set out above as the Original Issuance Date (in respect of the Original Principal Amount) (the “Original Issuance Date”) to the date set out above as the Issuance Date (the “Issuance Date”) and from and including the Issuance Date (in respect of the Outstanding Principal Amount) until such amounts become due and payable, whether upon the Maturity Date or acceleration, conversion, redemption or otherwise (in each case in accordance with the terms hereof) and Interest on any outstanding Principal at the Default Rate (if applicable) as set forth herein. The Original Issuance Date is the date of the first issuance of the AR Convertible Debenture, and the Issuance Date is the date of the first issuance of the Amended and Restated AR Convertible Debenture (as amended, amended and restated, extended, supplemented or otherwise modified in writing from time to time, this “Debenture”) regardless of the number of transfers and regardless of the number of instruments, which may be issued to evidence such

Debenture. This Debenture was issued pursuant to the Securities Purchase Agreement between the Company and the Buyers listed on the Schedule of Buyers attached thereto, dated as of May 18, 2026, as amended on June 29, 2026 (as it may be further amended from time to time, the “Securities Purchase Agreement”). Certain capitalized terms used herein are defined in Section (14).

(1)GENERAL TERMS

(a)Maturity Date. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest, and any other amounts outstanding pursuant to the terms of this Debenture. The “Maturity Date” shall be July 1, 2027. Other than as specifically permitted by this Debenture, the Company may not prepay or redeem any portion of the outstanding Principal and accrued and unpaid Interest.

(b)Interest Rate and Payment of Interest. Interest shall accrue on the outstanding Principal balance hereof at an annual rate equal to 7.50% (the “Interest Rate”), which Interest Rate shall increase to an annual rate of 18.00% (the “Default Rate”) upon the occurrence of an Event of Default (for so long as such event remains uncured). Interest shall be calculated based on a three hundred sixty-five (365)-day year and the actual number of days elapsed, to the extent permitted by applicable law.

(2)REDEMPTIONS.

(a)(i) Monthly Cash Redemptions. The Company shall, at its own option, (A) redeem in cash each Installment Amount (as defined in Section (14)) set forth on the Redemption Schedule (as defined in Section (14)) (a “Company Redemption”) on each applicable Redemption Date (as defined in Section (14)), subject to the provisions of this Section (2)(a)(i) and Section (2)(b) below, (B) provided the Equity Conditions are satisfied, allow such Installment Amount to be converted by the Holder in accordance with Section (4)(b), or (C) provided the Equity Conditions are satisfied, elect a combination of a Company Redemption and a conversion described in clause (B) above. On or prior to each Redemption Date, the Company shall deliver written notice in the form attached hereto as Exhibit II(a)(i) (each, an “Company Redemption Notice”) to the Holder which Company Redemption Notice shall either: (i) state that the Company elects to redeem, in whole or in part, the applicable Installment Amount in cash pursuant to a Company Redemption, and/or (ii) confirm that all or the applicable portion of the applicable Installment Amount may be converted by the Holder in whole, or in part, pursuant Section (4)(b) any time after the applicable Redemption Date.

If the Company does not timely deliver a Company Redemption Notice on or prior to the Redemption Date in accordance with this Section (2)(a)(i), then, provided the Equity Conditions are satisfied, the Company shall be deemed to have delivered a Company Redemption Notice confirming that the applicable Installment Amount may be converted by the Holder in accordance with Section (4)(b). For the avoidance of doubt, upon the delivery, or deemed delivery, of a Company Redemption Notice allowing such Installment Amount to be converted by the Holder, the Company’s obligation to redeem such Installment Amount pursuant to this Section (2)(a) shall be satisfied on the applicable Redemption Date and Interest on the related Principal amount shall cease to accrue as of the date that the Holder exercises its right to convert such Installment Amount in accordance with Section (4)(b).

2

Without limiting the foregoing or any other obligation hereunder of the Company, the Company acknowledges and agrees that the Company shall be deemed to have delivered a Company Redemption Notice, without regard to the Equity Conditions requirement, confirming that $4,220,000 in Principal amount, plus all accrued and unpaid interest in respect of such amount, of the December 29, 2026 Installment Amount (the “Investor Elected Mandatory Conversion Amount”) may be converted by the Holder in accordance with Section (4)(b).

Notwithstanding the foregoing, in the event that as of any Redemption Date there is an Event of Default or an Amortization Event in effect which has not been cured, then, in respect of such Redemption Date, (i) the Company shall be required to redeem in cash through a Company Redemption, and (ii) the applicable Installment Amount shall be the greater of the Installment Amount set forth on the Redemption Schedule or the Amortization Installment Amount.

Any Optional Redemptions made by the Company pursuant to this Debenture on or before any Redemption Date shall have the effect of adjusting the Redemption Schedule by reducing the Installment Amount of future payments coming due in reverse chronological order (i.e. starting with the latest payments first).

(ii)Mandatory Redemptions. The Company shall redeem in cash each Mandatory Redemption Amount (as defined in Section (14)) on each Redemption Date, subject to the provisions of this Section (2)(a)(ii) and Section (2)(b) below. On or prior to each Redemption Date with respect to a Mandatory Redemption Event, the Company shall deliver written notice in the form attached hereto as Exhibit II(a)(ii) (each, an “Mandatory Redemption Notice”) to the Holder which Mandatory Redemption Notice shall confirm the Mandatory Redemption Amount for a Mandatory Redemption Event that has occurred. Any such waivers of any particular Mandatory Redemption Amount shall not waive or be deemed a course of conduct to waive any additional or future Mandatory Redemption Amounts that arise under this Section 2(a)(ii).

If the Company does not timely deliver a Mandatory Redemption Notice on or prior to the applicable Redemption Date in accordance with this Section (2)(a)(ii), then an Event of Default shall automatically and immediately occur hereunder. Any redemption pursuant to this Section (2)(a)(ii) may, at the Company’s discretion, be pursuant to a Mandatory Redemption Notice given prior to the completion or occurrence of a Mandatory Redemption Event, and such redemption or notice may, at the Holder’s discretion, be subject to the completion or occurrence of the related Mandatory Redemption Event or other transaction or event, as the case may be.

Any Mandatory Redemption Amounts shall be paid in cash under this Debenture and the Other Debentures pro rata as provided herein and therein.

Any Mandatory Redemption Amounts actually paid in cash on or before any Redemption Date shall have the effect of adjusting the Redemption Schedule by reducing the Installment Amount of future payments coming due in reverse chronological order (i.e., starting with the latest payments first).

3

Notwithstanding anything to the contrary herein, a Mandatory Redemption Amount shall not include the Investor Elected Mandatory Conversion Amount unless otherwise agreed in writing by the Holder.

(b)Company Redemption; Mandatory Redemption. If (i) the Company elects or is required to make a Company Redemption in cash in accordance with Section (2)(a)(i), then the amount to be paid shall be the sum of the applicable Installment Amount (or Amortization Installment Amount, if applicable) or (ii) the Company is required to pay any Mandatory Redemption Amount in cash in accordance with Section 2(a)(ii), then the amount to be paid in cash shall be the sum of the Mandatory Redemption Amount (in either such case of clause (b)(i) above or (b)(ii) above, collectively referred to herein as the “Redemption Amount”). The Redemption Amount shall be paid by the Company on or before such Redemption Date, by wire transfer of immediately available funds.

(c)Company Additional Optional Redemption. The Company at its option shall have the right, but not the obligation, to redeem early a portion or all amounts outstanding under this Debenture as described in this Section (each such option, an “Optional Redemption”); provided, that the Company provides the Holder with written notice (each, an “Optional Redemption Notice”) of its desire to exercise an Optional Redemption, which Optional Redemption Notice shall be delivered to the Holder after the close of regular trading hours on a Trading Day. Each Optional Redemption Notice shall be irrevocable and shall specify the outstanding balance of the Debenture to be redeemed and the applicable Optional Redemption Amount. Notwithstanding anything to the contrary herein, an Optional Redemption Amount shall not include the Investor Elected Mandatory Conversion Amount unless otherwise agreed in writing by the Holder.

(i)Change of Control Transaction Optional Redemption. The Company at its option shall have the right, but not the obligation, to redeem early all, but not less than all, amounts outstanding under this Debenture if a Change of Control Transaction occurs (a “Change of Control Transaction Optional Redemption”). The “Optional Redemption Amount” in respect of a Change of Control Transaction Optional Redemption shall be an amount equal to (a) the outstanding Principal balance being redeemed by the Company plus (b) all accrued and unpaid interest hereunder as of the date of such redemption.

(iii)    After receipt of an Optional Redemption Notice, the Holder shall have seven (7) Trading Days (beginning with the Trading Day immediately following the date the Optional Redemption Notice is delivered to the Holder in accordance with the terms of this Section (2)(c)) to elect to convert the Principal amount, and accrued and unpaid Interest, subject to the Optional Redemption. On the eighth (8th) Trading Day following the delivery of the applicable Optional Redemption Notice, the Company shall deliver to the Holder the Optional Redemption Amount with respect to the Principal amount redeemed to the extent not converted or otherwise repaid after giving effect to the conversions or other payments made during such seven (7) Trading Day period.

(d)Additional Redemptions. Without limiting the foregoing, the Company affirms and confirms its obligations to repay principal under this Debenture in cash or, at the election of the Buyer, convert amounts required to be paid by conversion into Common Shares as set forth in Section (4)(s)(v) of the Securities Purchase Agreement. Any failure to take the steps required under such Section (4)(s)(v) shall give rise to an Event of Default hereunder

(e)Payments Generally.

4

(i)Payment Dates. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day.

(ii)Principal Payments. Each payment of Principal (whether paid in cash or by conversion into Common Shares) under this Debenture shall be accompanied by all accrued and unpaid Interest thereon (which shall be paid in the same manner as such Principal payment).

(3)EVENTS OF DEFAULT.

(a)An “Event of Default”, wherever used herein, means any one of the following events (whatever the reason and whether it shall be voluntary or involuntary or effected by operation of law or pursuant to any judgment, decree or order of any court, or any order, rule or regulation of any administrative or governmental body, in each case of competent jurisdiction) shall have occurred:

No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon.

(4)CONVERSION OF DEBENTURE. This Debenture shall be convertible into shares of Common Stock, on the terms and conditions set forth in this Section (4).

(a)Conversion Right. Subject to the limitations of Section (4)(d), at such time or times on or after the Original Issuance Date as provided herein, the Holder shall be entitled to convert any portion or such portion of the outstanding and unpaid Conversion Amount (as defined below) that may be subject to conversion by the Investor as provided herein into fully paid and nonassessable shares of Common Stock in accordance with Section (3)(b) or Section (4)(b), at the applicable Conversion Price (as defined below). The number of shares of Common Stock issuable upon conversion of any Conversion Amount pursuant to this Section (4)(a) shall be determined by dividing (x) such Conversion Amount by (y) the applicable Conversion Price. The Company shall not issue any fraction of a share of Common Stock upon any conversion. All calculations under this Section (4) shall be rounded to the nearest $0.0001. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Stock upon conversion of any Conversion Amount.

(i)“Conversion Amount” means the portion of the Principal, Interest, or other amounts outstanding under this Debenture to be converted or otherwise with respect to which this determination is being made.

(ii)“Conversion Price” means, as of any Conversion Date (as defined below) or other date of determination with respect to a conversion pursuant to the terms of this Debenture, 97% of the lowest daily VWAP for the Common Stock during the four (4) consecutive Trading Days immediately preceding the Conversion Date (the “Market Price”), but which Market Price shall not be lower than the Floor Price. The Conversion Price shall be adjusted from time to time pursuant to the other terms and conditions of this Debenture.

(b)Market Price Conversions. For (i) any Installment Amount (or other additional amounts as may be agreed by the Company) subject to a Company Redemption Notice confirming that the applicable Installment Amount (or other additional amounts as may be agreed by the Company) or (ii) the portion of the December 29, 2026 Installment Amount that may be converted by the Holder in the amount of the Investor Elected Mandatory Conversion Amount (or other additional amounts as may be agreed by the Company), in either such case of sub-clauses (b)(i) and (b)(ii) herein, for which the Holder may elect to convert, at any time and from time to time after such applicable Redemption Date, the Holder may convert a Conversion Amount up to the applicable Installment Amount (or other additional amounts as may be agreed

8

by the Company, or any portion thereof) at the Conversion Price by serving a Conversion Notice on the Company in accordance with Section (4)(c).

(c)Mechanics of Conversion.

(i)Optional Conversion. To convert any Conversion Amount into shares of Common Stock on any date (a “Conversion Date”), the Holder shall (A) transmit by email (or otherwise deliver), for receipt on or prior to 11:59 p.m., New York time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit III (the “Conversion Notice”) to the Company and (B) if required by Section (4)(c)(iii), surrender this Debenture to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Debenture in the case of its loss, theft or destruction). On or before the first (1st) Trading Day following the date of receipt of a Conversion Notice (the “Share Delivery Date”), the Company shall (X) if legends are not required to be placed on certificates or the book-entry position of the Shares of Common Stock and provided that the Transfer Agent is participating in the Depository Trust Company’s (“DTC”) Fast Automated Securities Transfer Program, instruct such transfer agent to credit such aggregate number of Shares of Common Stock to which the Holder shall be entitled to the Holder’s or its designee’s balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate or book-entry position, registered in the name of the Holder or its designee, for the number of Shares of Common Stock to which the Holder shall be entitled which certificates shall bear restrictive legends unless not required pursuant to rules and regulations of the Commission. If this Debenture is physically surrendered for conversion and the outstanding Principal of this Debenture is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Debenture and at its own expense, issue and deliver to the holder a new Debenture representing the outstanding Principal not converted. The Person or Persons entitled to receive the Shares of Common Stock issuable upon a conversion of this Debenture shall be treated for all purposes as the record holder or holders of such Shares of Common Stock upon the receipt by the Company of a Conversion Notice.

(ii)Company’s Failure to Timely Convert. If the Company shall fail, for any reason or for no reason, on or prior to the applicable Share Delivery Date (or, if such failure occurs through no fault of the Company, on or prior to the second (2nd) Trading Day following the Share Delivery Date) to issue and deliver a certificate to the Holder or credit the Holder’s balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon such Holder’s conversion of any Conversion Amount (a “Conversion Failure”), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company (a “Buy-In”), then the Company shall, within three (3) Business Days after the Holder’s request and in the Holder’s discretion, either (i) pay cash to the Holder in an amount equal to the Holder’s total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point the Company’s obligation to deliver such certificate (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Stock to which the Holder is entitled with respect to such Conversion Notice and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of Common Stock, multiplied by (B) the Closing Price on the Conversion Date.

9

(iii)Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Debenture in accordance with the terms hereof, the Holder shall not be required to physically surrender this Debenture to the Company unless (A) the full Conversion Amount represented by this Debenture is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Debenture upon physical surrender of this Debenture. The Holder and the Company shall maintain records showing the Principal and Interest converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Debenture upon any conversion.

(d)Limitations on Conversions.

(i)Beneficial Ownership. The Holder shall not have the right to convert any portion of this Debenture to the extent that after giving effect to such conversion the Holder, together with any Affiliate thereof, would beneficially own (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to such conversion (the “Beneficial Ownership Cap”). Since the Holder will not be obligated to report to the Company the number of shares of Common Stock it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of the Beneficial Ownership Cap, the Holder shall have the authority and obligation to determine whether the Beneficial Ownership Cap will limit any particular conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the Principal amount of this Debenture is convertible shall be the responsibility and obligation of the Holder. If the Holder has delivered a Conversion Notice for a Principal amount of this Debenture that, without regard to any other shares that the Holder or its Affiliates may beneficially own, would result in the issuance in excess of the Beneficial Ownership Cap, the Company shall notify the Holder of this fact and shall honor the conversion for the maximum Principal amount permitted to be converted on such Conversion Date in accordance with Section (4)(a) and, any Principal amount tendered for conversion in excess of the permitted amount hereunder shall remain outstanding under this Debenture. The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than sixty-five (65) days prior notice to the Company. Other Holders shall be unaffected by any such waiver.

(ii)Principal Market Limitation. Notwithstanding anything in this Debenture to the contrary, the Company shall not issue any Shares of Common Stock upon conversion of this Debenture, or otherwise, if the issuance of such Shares of Common Stock, together with any Shares of Common Stock issued in connection with any other related transactions that may be considered part of the same series of transactions, would exceed the aggregate number Shares of Common Stock that the Company may issue in a transaction in compliance with the Company’s obligations under the rules or regulations of the Principal Market and shall be referred to as the “Exchange Cap,” except that such limitation shall not apply if the Company’s stockholders have approved such issuances on such terms in excess of the Exchange Cap in accordance with the rules and regulations of Principal Market.

(e)Other Provisions.

(i)All calculations under this Section (4) shall be rounded to the nearest $0.0001 or whole share.

(ii)So long as this Debenture or any Other Debentures remain outstanding, the Company shall have reserved from its duly authorized share capital, and shall

10

have instructed the Transfer Agent to irrevocably reserve, the maximum number of Shares of Common Stock issuable upon conversion of this Debenture and the Other Debentures (assuming for purposes hereof that (x) this Debenture and such Other Debentures are convertible at the Floor Price as of the date of determination, and (y) any such conversion shall not take into account any limitations on the conversion of the Debenture or Other Debentures set forth herein or therein (the “Required Reserve Amount”)), provided that at no time shall the number of Shares of Common Stock reserved pursuant to this Section (4)(e)(ii) be reduced other than pursuant to the conversion of this Debenture and the Other Debentures in accordance with their terms, and/or cancellation, or reverse stock split. If at any time while this Debenture or any Other Debentures remain outstanding, the Company does not have a sufficient number of authorized and unreserved Shares of Common Stock to satisfy the obligation to reserve for the issuance the Required Reserve Amount, the Company will promptly take all corporate action necessary to propose to a meeting of its stockholders an increase of its authorized share capital necessary to meet the Company’s obligations pursuant to this Debenture, and cause its board of directors to recommend to the stockholders that they approve such proposal.

(iii)Nothing herein shall limit a Holder’s right to pursue actual damages or declare an Event of Default pursuant to Section (3) herein for the Company’s failure to deliver certificates representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief, in each case without the need to post a bond or provide other security. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

(iv)Legal Opinions. The Company is obligated to use commercially reasonable efforts to cause its legal counsel to deliver legal opinions to the Company’s transfer agent in connection with any legend removal upon the expiration of any holding period or other requirement for which the Underlying Shares may bear legends restricting the transfer thereof (i) following any sale of such Underlying Shares pursuant to Rule 144, (ii) if such Underlying Shares are eligible for sale and about to be sold under Rule 144, or (iii) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC); provided, however, that such Holder has delivered such reasonably requested representations to such transfer agent, the Company and the Company’s legal counsel in connection with the request for such opinion. To the extent a legal opinion is not provided (either timely or at all), then, in addition to being an Event of Default hereunder, the Company agrees to reimburse the Holder for all reasonable costs incurred by the Holder in connection with any legal opinions paid for by the Holder in connection with the sale or transfer of the Underlying Shares of Common Stock. The Holder shall notify the Company of any such costs and expenses it incurs that are referred to in this section from time to time and all amounts owed hereunder shall be paid by the Company with reasonable promptness.

(5)Adjustments to Conversion Price

(a)Adjustment of Conversion Price upon Subdivision or Combination of Common Stock. If the Company, at any time while this Debenture is outstanding, shall (a) pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Stock or any other equity or equity equivalent securities payable in shares of Common Stock, (b) subdivide outstanding shares of Common Stock into a larger number of shares, (c) combine (including by way of reverse stock split) outstanding shares of Common Stock into a smaller number of shares, or (d) issue by reclassification of shares of the Common Stock any shares of capital stock of the Company, then the Floor Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of

11

Common Stock outstanding after such event. Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(b)[Reserved].

(c)Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities or other assets with respect to or in exchange for shares of Common Stock that is not a Change of Control Transaction (a “Corporate Event”), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Debenture, at the Company’s option, (i) in addition to the shares of Common Stock receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such shares of Common Stock had such shares of Common Stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Debenture) or (ii) in lieu of the shares of Common Stock otherwise receivable upon such conversion, such securities or other assets received by the holders of shares of Common Stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Debenture initially been issued with conversion rights for the form of such consideration (as opposed to shares of Common Stock) at a conversion rate for such consideration commensurate with the Conversion Price. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Holder. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Debenture.

(d)Notice of Adjustments to Conversion Price. Whenever the Conversion Price is adjusted pursuant to Section (5) hereof, the Company shall promptly provide the Holder with a written notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(e)Mergers or Consolidations; Etc. In case of any (1) merger or consolidation of the Company with or into another Person, or (2) sale by the Company of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, in one or a series of related transactions, a Holder shall have the right to (A) convert the aggregate amount of this Debenture then outstanding into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Stock following such merger, consolidation or sale, and such Holder shall be entitled upon such event or series of related events to receive such amount of securities, cash and property as the shares of Common Stock into which such aggregate Principal amount of this Debenture could have been converted immediately prior to such merger, consolidation or sales would have been entitled. The terms of any such merger, sale or consolidation shall include such terms so as to continue to give the Holder the right to receive the securities, cash and property set forth in this Section upon any conversion or redemption following such event. This provision shall similarly apply to successive such events.

(6)REISSUANCE OF THIS DEBENTURE.

(a)Register. The Company shall maintain at its principal executive offices or with the Transfer Agent (or at such other office or agency of the Company as it may designate by notice to each holder of this Debenture ), a register for this Debenture in which the Company shall record the name and address of the Person in whose name this Debenture has been issued

12

(including the name and address of each transferee), the principal amount (and stated interest) of this Debenture held by such Person. The Company shall maintain the register in a manner that complies with the “registered form” requirements in Section 5f.103-1(c) of the United States Treasury Regulations.

(b)Transfer. Holder shall not transfer this Debenture other than to its Affiliates. If this Debenture is to be transferred, the Holder shall surrender this Debenture to the Company, whereupon the Company will forthwith issue and deliver to the Holder a new Debenture (in accordance with Section (6)(e)), registered in the name of the registered transferee or assignee, representing the outstanding Principal being transferred by the Holder (along with any accrued and unpaid Interest thereof) and, if less than the entire outstanding Principal is being transferred, a new Debenture (in accordance with Section (6)(e)) to the Holder representing the outstanding Principal not being transferred. The Holder and any assignee, by acceptance of this Debenture, acknowledge and agree that, by reason of the provisions of Section (4)(c)(iii) following conversion or redemption of any portion of this Debenture, the outstanding Principal represented by this Debenture may be less than the Principal stated on the face of this Debenture.

(c)Lost, Stolen or Mutilated Debenture. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Debenture, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and substance and, in the case of mutilation, upon surrender and cancellation of this Debenture, the Company shall execute and deliver to the Holder a new Debenture (in accordance with Section (6)(e)) representing the outstanding Principal.

(d)Debenture Exchangeable for Different Denominations. This Debenture is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Debenture or Debentures (in accordance with Section (6)(e)) representing in the aggregate the outstanding Principal of this Debenture, and each such new Debenture will represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender.

(e)Issuance of New Debentures. Whenever the Company is required to issue a new Debenture pursuant to the terms of this Debenture, such new Debenture (i) shall be of like tenor with this Debenture, (ii) shall represent, as indicated on the face of such new Debenture, the Principal remaining outstanding (or in the case of a new Debenture being issued pursuant to Section (6)(a) or Section (6)(d), the Principal designated by the Holder which, when added to the Principal represented by the other new Debentures issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Debenture immediately prior to such issuance of new Debentures), (iii) shall have an issuance date, as indicated on the face of such new Debenture, which is the same as the Original Issuance Date of this Debenture, (iv) shall have the same rights and conditions as this Debenture, and (v) shall represent accrued and unpaid Interest from and including the Original Issuance Date to the Issuance Date in respect of the Original Principal Amount and from and including the Issuance Date in respect of the Outstanding Principal Amount.

(7)Any notices, consents, waivers or other communications required or permitted to be given under the terms hereof must be in writing by letter or electronic mail (“e-mail”) and will be deemed to have been delivered (i) upon receipt, when delivered personally, (ii) one (1) Business Day after deposit with an overnight courier service with next day delivery specified, as applicable or (iii) receipt, when sent by e-mail, and, in each case of the foregoing clauses (i), (ii) and (iii), properly addressed to the party to receive the same.

(10)CHOICE OF LAW; VENUE; WAIVER OF JURY TRIAL

(a)Governing Law. This Debenture and the rights and obligations of the Parties hereunder shall, in all respects, be governed by, and construed in accordance with, the laws (excluding the principles of conflict of laws) of the State of New York (the “Governing Jurisdiction”) (including Section 5-1401 and Section 5-1402 of the General Obligations Law of the State of New York), including all matters of construction, validity and performance.

(b)Jurisdiction; Venue; Service.

(i)The Company and the Holder each hereby irrevocably consent to the non-exclusive personal jurisdiction of the state courts of the Governing Jurisdiction and, if a basis for federal jurisdiction exists, the non-exclusive personal jurisdiction of any United States District Court for the Governing Jurisdiction.

(ii)The Company and the Holder each agrees that venue shall be proper in any court of the Governing Jurisdiction or, if a basis for federal jurisdiction exists, in any United States District Court in the Governing Jurisdiction. The Company waives any right to object to the maintenance of any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, in any of the state or federal courts of the Governing Jurisdiction on the basis of improper venue or inconvenience of forum.

(iii)Any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or tort or otherwise, brought by the Company against the Holder arising out of or based upon this Debenture or any matter relating to this Debenture, or any other Transaction Document, or any contemplated transaction, shall be brought in a court only in the Governing Jurisdiction. The Company shall not file any counterclaim against the Holder in any suit, claim, action, litigation or proceeding brought by the Holder against the Company in a jurisdiction outside of the Governing Jurisdiction unless under the rules of the court in which the Holder brought such suit, claim, action, litigation or proceeding the counterclaim is mandatory, and not permissive, and would be considered waived unless filed as a counterclaim in the suit, claim, action, litigation or proceeding instituted by the Holder against the Company. The Company agrees that any forum outside the Governing Jurisdiction is an inconvenient forum and that any suit, claim, action, litigation or proceeding brought by the Company against the Holder in any court outside the Governing Jurisdiction should be dismissed or transferred to a court located in the Governing Jurisdiction. Furthermore, the Company irrevocably and unconditionally agrees that it will not bring or commence any suit, claim, action, litigation or proceeding of any kind or description, whether in law or equity, whether in contract or in tort or otherwise, against the Holder arising out of or based upon this Debenture or any matter relating to this Debenture, or any other Transaction Document, or any contemplated transaction, in any forum other than the courts of the State of New York sitting in New York County, and the United States District Court of the Southern District of New York, and any appellate court from any thereof, and each of the parties hereto irrevocably and unconditionally submits to the jurisdiction of such courts and agrees that all claims in respect of any such suit, claim, action, litigation or proceeding may be heard and determined in such New York State Court or, to the fullest extent permitted by applicable law, in such federal court. The Company and the Holder agree that a final judgment in any such suit, claim, action, litigation or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law.

(iv)The Company and the Holder irrevocably consent to the service of process out of any of the aforementioned courts in any such suit, claim, action, litigation or proceeding by e-mail or the mailing of copies thereof by registered or certified mail postage

15

prepaid, to it at the e-mail address or physical address, as applicable, provided for notices in this Debenture, such service to become effective thirty (30) days after the date of e-mail or mailing, as applicable.

(v)Nothing herein shall affect the right of the Holder to serve process in any other manner permitted by law or to commence legal proceedings or to otherwise proceed against the Company or any other Person in the Governing Jurisdiction or in any other jurisdiction.

(c)WAIVER OF JURY TRIAL. THE PARTIES MUTUALLY WAIVE ALL RIGHT TO TRIAL BY JURY OF ALL CLAIMS OF ANY KIND ARISING OUT OF OR BASED UPON THIS DEBENTURE OR ANY MATTER RELATING TO THIS DEBENTURE, OR ANY OTHER TRANSACTION DOCUMENT, OR ANY CONTEMPLATED TRANSACTION. THE PARTIES ACKNOWLEDGE THAT THIS IS A WAIVER OF A LEGAL RIGHT AND THAT THE PARTIES EACH MAKE THIS WAIVER VOLUNTARILY AND KNOWINGLY AFTER CONSULTATION WITH COUNSEL OF THEIR RESPECTIVE CHOICE. THE PARTIES AGREE THAT ALL SUCH CLAIMS SHALL BE TRIED BEFORE A JUDGE OF A COURT HAVING JURISDICTION, WITHOUT A JURY.

(11)TAX MATTERS.

(a)On or prior to the Original Issuance Date (and from time to time thereafter upon the reasonable request of the Company), the Holder shall provide the Company with a duly completed and executed Internal Revenue Service Form W-9 or appropriate W-8 (and, if applicable, a certificate establishing that such Holder satisfies the portfolio interest exemption).

(e)all liabilities and obligations of the Company under the SPA and the Company and the other Guarantors and Grantors under the other Transaction Documents are valid and enforceable and are not impaired or limited by the execution or effectiveness of this Amendment or the other Transaction Documents. No financing statement or other public notice with respect to all or any part of the Collateral is on file or of record in any public office, except filings evidencing Permitted Liens.

7.Reference to SPA and Transaction Documents; No Waiver.

(a)References. Upon the effectiveness of this Amendment, each reference in the SPA to “this Agreement,” “hereunder,” “hereof,” “herein” or words of like import shall mean and be a reference to the SPA, as amended hereby. The term “Transaction Documents” as

8

defined in Section 3(b) of the SPA shall include (in addition to the Transaction Documents described in the SPA) this Amendment and any other agreements, instruments or other documents executed in connection herewith.

(b)No Waiver. The Buyer’s failure, at any time or times hereafter, to require strict performance by the Company of any provision or term of the SPA, this Amendment, or the other Transaction Documents shall not waive, affect or diminish any right of the Buyer hereafter to demand strict compliance and performance herewith or therewith. Any suspension or waiver by the Buyer of a breach of this Amendment or any Event of Default under the SPA shall not, except as expressly set forth in a writing signed by the Buyer, suspend, waive or affect any breach of this Amendment or any Event of Default under the SPA, whether the same is prior or subsequent thereto and whether of the same or of a different kind or character. None of the undertakings, agreements, warranties, covenants, and representations of the Company contained in this Amendment, shall be deemed to have been suspended or waived by the Buyer unless such suspension or waiver is (i) in writing and signed by the Buyer and (ii) delivered to the Company. In no event shall the Buyer’s execution and delivery of this Amendment establish a course of dealing among the Buyer, the Company, or any other obligor, or in any other way obligate the Buyer to hereafter provide any consents, amendments, or waivers with respect to the SPA or other Transaction Documents. The terms and provisions of this Amendment shall be limited precisely as written and shall not be deemed (x) to be a consent to any waiver, amendment or modification of any other term or condition of the SPA or of any of the Transaction Documents (except as expressly provided herein); or (y) to prejudice any right or remedy which the Buyer may now have under or in connection with the SPA or any of the Transaction Documents. Neither this Amendment nor any uncertainty or ambiguity herein shall be construed or resolved against the Buyer, whether under any rule of construction or otherwise.

(c)Full Force and Effect. Except as expressly provided herein, the SPA and all other Transaction Documents shall remain in full force and effect against the Company and are hereby ratified and confirmed by the Company. This Amendment shall not be construed as a waiver or amendment of any other provision of the SPA or for any purpose except as expressly set forth herein. Notwithstanding the foregoing, in the event of a conflict between the provisions of this Amendment and the SPA, the terms of this Amendment shall supersede such provisions and shall control.

8.Severability; Amendments. Whenever possible, each provision of this Amendment shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Amendment shall be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions of this Amendment. The parties hereto have participated jointly in the negotiation and drafting of this

9

Amendment. In the event an ambiguity or question of intent or interpretation arises, this Amendment shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this Amendment. This Amendment may be amended or modified only by mutual agreement of the parties evidenced in writing and signed by the party to be charged therewith.

9.Incorporation by Reference. Sections 9(a) (Governing Law), 9(b) (Jurisdiction; Venue; Service), 9(c) (Waiver of Jury Trial), 9(d) (Counterparts), 9(e) (Headings; Gender), 9(f) (Entire Agreement, Amendments), 9(g) (Notices), 9(h) (Successors and Assigns), 9(j) (No Strict Construction) of the SPA are incorporated herein, mutatis mutandis, as if fully set forth herein with references to this “Agreement” to be understood to refer to the SPA, as amended by this Amendment.

Waiver, Consent and Amendment No. 1 to Credit Agreement

This WAIVER, CONSENT AND AMENDMENT NO. 1 TO CREDIT AGREEMENT, dated as of June 29, 2026 (this “Agreement”), is by and between CROSS TRAILS ENERGY STORAGE PROJECT, LLC, a Delaware limited liability company (the “Borrower”) and the Lenders party hereto constituting the Majority Lenders (the “Majority Lenders”).

R e c i t a l s

A.WHEREAS, the Borrower, the Agents and the Lenders are parties to that certain Credit Agreement, dated as of July 23, 2025 (as amended, restated, amended and restated, supplemented or otherwise modified from time to time pursuant to the terms hereof, the “Credit Agreement”), pursuant to which the Lenders have made certain credit available to and on behalf of the Borrower.

B.WHEREAS, pursuant to Section 6.17 of the Credit Agreement, the Borrower is required to maintain (i) a Historical Debt Service Coverage Ratio of at least 1.10:1.00 and (ii) a Pro Forma Debt Service Coverage Ratio of at least 1.10:1.00, in each case, measured as of the end of each fiscal quarter.

C.WHEREAS, pursuant to Section 7.01(b)(i) of the Credit Agreement, the failure by the Borrower to comply with Section 6.17 of the Credit Agreement constitutes an Event of Default;

D.WHEREAS, at the end of the fiscal quarter ended on March 31, 2026, the Borrower was unable to maintain the required Historical Debt Service Coverage Ratio and Pro Forma Debt Service Coverage Ratio, and (ii) as of the fiscal quarter ending June 30, 2026, without giving effect to the equity contribution specified below, the Borrower would be unable to maintain the required Historical Debt Service Coverage Ratio and Pro Forma Debt Service Coverage Ratio (the “Specified Default”);

E.WHEREAS, the Borrower now requests that the Lenders waive any Default or Event of Default arising in connection with or as a result of the Specified Default (the “Requested Waiver”) and permit the Borrower (i) to receive certain cash equity contributions in an aggregate amount of $[***] from the Sponsor which will allow the Borrower to comply with the Debt Service Coverage Ratio for the fiscal quarters ending March 31, 2026 and June 30, 2026 (the “Historical Cure Amounts”) and an historical revenue credit in respect of insurance proceeds reasonably expected to be received by the Borrower during the first fiscal quarter of 2026 in an amount of $[***] (the “Historical Revenue Credit”) and (ii) to apply the Historical Cure Amounts and the Historical Revenue Credit to cure the Specified Default as further set forth below.

F.WHEREAS, the Borrower and the Lenders desire to amend the Credit Agreement to provide for an equity cure right for the Borrower; and

G.WHEREAS, pursuant to Section 9.03 of the Credit Agreement, the consent of the Majority Lenders is required for any amendments or modifications of the Credit Agreement;

H.NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

Section 1.Defined Terms. Each capitalized term which is defined in the Credit Agreement, but which is not defined in this Agreement, shall have the meaning ascribed to such term in the Credit Agreement. Unless otherwise indicated, all section, exhibit and schedule references in this Agreement refer to sections, exhibits or schedules of the Credit Agreement.

Section 2.Consents and Waiver.

As of the Effective Date, subject to the conditions precedent set forth in Section 5 and in reliance upon the representations, warranties and covenants of the Borrower contained in this Agreement, the undersigned Lenders hereby (a) grant the Requested Waiver and (b) consent to the Borrower’s application of the Historical Cure Amounts and Historical Revenue Credit within ten (10) Business Days after the Effective Date hereof to cure the Specified Default.

Section 3.Amendment.

3.1As of the Effective Date, subject to the conditions precedent set forth in Section 5 and in reliance upon the representations, warranties and covenants of the Borrower contained in this Agreement, the undersigned Lenders hereby consent to add the following new Section 7.06 to the Credit Agreement:

(a)“7.06    Cure Right.

(b)Notwithstanding anything to the contrary contained in Section 7.01, a failure of the Borrower to comply with the requirements of the financial covenants set forth in Section 6.17 (each, a “Financial Covenant”) shall not constitute an Event of Default hereunder if at any time on or prior to the tenth (10th) Business Day after the date on which the financial statements of the Borrower referred to in Sections 5.01(a) or 5.01(b) are required to be delivered with respect to the applicable fiscal quarter (the last day of such period being the “Anticipated Cure Deadline”), the Borrower shall have received cash contributions from the Pledgor or any direct or indirect owner of the Pledgor (the “Cure Right”), the proceeds of which shall not exceed the amount necessary to cure the Financial Covenant breach and shall be applied in accordance with the Accounts Agreement to increase Net Cash Flow and ensure compliance with any such Financial Covenant.

(c)Upon receipt by the Borrower of the cash proceeds pursuant to the exercise of the Cure Right (the “Cure Amount”), such Financial Covenant shall be recalculated, giving effect to a pro forma increase in the Net Cash Flow for such fiscal quarter and the applicable subsequent periods that include such fiscal quarter in an amount equal to such Cure Amount; provided that (i) such pro forma increase shall be made solely for the purpose of determining the existence of a Default or Event of Default under such Financial Covenant with respect to any applicable period that includes such fiscal quarter and not for any other purposes under any Loan Document, (ii) there shall be no reduction in Indebtedness in connection with any Cure Amount contributed in order to comply with such Financial Covenant and no Cure Amount will reduce Indebtedness in the calculations of such Financial Covenant for such fiscal quarter or any subsequent fiscal quarter and (iii) the Cure Amount shall not be taken into account when assessing whether the Borrower has satisfied the Distribution Conditions.

(d)If, after the exercise of any Cure Right and the recalculations pursuant to clause (b) of this Section, the Borrower shall be in compliance with the requirements of such Financial Covenant as of the end of such fiscal quarter, the Borrower shall be deemed to have been in compliance with such Financial Covenant as of the relevant date

Page 2

of determination with the same effect as if there had been no failure to comply with such Financial Covenant on such date, and the applicable Default or Event of Default shall be deemed to have never occurred.

(e)The Borrower shall have the right to exercise the Cure Right four (4) times during the term of this Agreement and once in consecutive fiscal quarter periods; provided that the cure of the Specified Default effected through the application of the Historical Cure Amounts and the Historical Revenue Credit as set forth in the Waiver, Consent and Amendment No 1 to the Credit Agreement, dated as of June 29, 2026, shall not count toward, and shall be in addition to, such four (4) permitted exercises of the Cure Right. The Borrower shall not be allowed to use the Cure Right for the fiscal quarter ending September 30, 2026.

(f)Upon receipt by the Administrative Agent of written notice, on or prior to the Anticipated Cure Deadline, that the Borrower intends to exercise the Cure Right in respect of any failure to comply with a Financial Covenant, neither the Administrative Agent nor the Lenders shall be permitted to accelerate all or any portion of the Loans, charge interest at the Default Rate or exercise remedies against the Collateral or any other rights and remedies under any of the Loan Documents that are available during the continuance of an Event of Default on the basis of a failure to comply with the requirements of such Financial Covenant, unless and until such failure is not cured pursuant to the exercise of the Cure Right on or prior to the Anticipated Cure Deadline; provided, that nothing contained herein shall prevent or prohibit the Administrative Agent and the Lenders from exercising any and all rights as a result of any other Event of Default.”

Section 4.Limited Effect.

The consents and waiver set forth in Section 2 of this Agreement and the amendment set forth in Section 3 of this Agreement shall be effective only in the specific instances described herein and nothing herein shall be construed to limit or bar any rights or remedies of the Secured Parties. For the avoidance of doubt and without limiting the generality of the foregoing, the parties agree that, other than as expressly contemplated in this Agreement, no change, amendment, waiver or consent with respect to the terms and provisions of any of the Loan Documents is intended or contemplated hereby (which terms and provisions remain unchanged and in full force and effect other than as expressly set forth herein).

6.2Neither the execution or delivery of this Agreement by the Borrower, nor the performance by the Borrower of this Agreement and the Credit Agreement or compliance with

Page 3

the terms and provisions thereof and the other transactions contemplated therein, will (a) contravene, result in any breach of, or constitute a default under, or result in the creation of any Lien (other than the creation of any Liens pursuant to the Loan Documents) in respect of any Property of the Borrower under, any indenture, mortgage, deed of trust, loan, purchase or credit agreement, lease, limited liability company agreement, or any other agreement or instrument to which the Borrower is bound or by which the Borrower or any of its properties may be bound or affected, (b) conflict with or result in a breach of any of the terms, conditions, or provisions of any order, judgment, decree, or ruling of any court, arbitrator, or Governmental Authority applicable to the Borrower, or (c) violate any provision of any statute or other rule or regulation of any Governmental Authority applicable to the Borrower.

In the event such model does not support the current debt sizing under the original underwriting debt service coverage ratio thresholds ([***]) the parties may agree to enter into an agreement whereby the amount of the Borrower’s Indebtedness will be resized to take into account such updated model.

Section 8.Miscellaneous.

8.1Counterparts. This Agreement may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed shall be deemed to be an original and all of which taken together shall constitute one and the same agreement.
