(Dollars in thousands):	Maturity Date	Interest Rate			March 31, 2024		December 31, 2023
Convertible Note	July 25, 2024		*18	%	$	6,216	$	8,474

* Default interest was waived on March 10, 2023, and no further interest applied on the Convertible Note for the remainder of the year.

On October 25, 2021, pursuant to a Securities Purchase Agreement (the “October SPA”), the Company issued to certain accredited investors (the “Noteholders”) (i) secured convertible notes in an aggregate principal amount of $16.3 million for an aggregate purchase price of $15 million (collectively, the “October Secured Notes”), which were, subject to certain conditions, convertible at any time by the investors, into an aggregate of 1,776,073 shares of the Company’s common stock, at a price per share of $9.18 and (ii) Class A, Class B and Class C common stock purchase warrants (collectively, the “October Warrants”) to purchase up to an aggregate of 1,776,073 shares of common stock, at an initial exercise price of $12.50, $15 and $18 per share, respectively. The October Warrants are legally detachable and can be separately exercised immediately for five years upon issuance, subject to applicable Nasdaq rules.

The October Secured Notes, subject to an original issue discount of 8%, had a maturity date (the “Maturity Date”) of October 25, 2022, which was extended to April 25, 2023 pursuant to the Addendum Amendment (as defined below), upon which date the October Secured Notes shall be payable in full. Commencing on the Maturity Date and also five (5) days after the occurrence of any Event of Default (as defined in the October Secured Notes), interest on the October Secured Notes will accrue at an interest rate equal to the lesser of 18% per annum or the maximum rate permitted under applicable law. If any Event of Default or a Fundamental Transaction (as defined in the October Secured Notes) or a Change of Control (as defined in the October Secured Notes) occurs, the outstanding principal amount of the October Secured Notes, liquidated damages and other amounts owing in respect thereof through the date of acceleration, will become, at the Noteholder’s election, immediately due and payable in cash at the Mandatory Default Amount (as defined in the October Secured Notes). Under the original terms, the October Secured Notes could not be prepaid, redeemed or mandatorily converted without the consent of the Noteholders. The obligations of the Company pursuant to the October Secured Notes are (i) secured to the extent and as provided in the Security Agreement, dated as of October 25, 2021, by and among the Company, MTI Instruments (a former subsidiary of SHI in which was sold in April 2022), and SCI, Soluna MC, LLC and Soluna SW, LLC (both of which are wholly owned subsidiaries of SCI, and together with MTI Instruments and SCI, the “Subsidiary Guarantors”), and Collateral Services LLC (the “Collateral Agent”), as collateral agent for the Noteholders; and (ii) guaranteed, jointly and severally, by the Subsidiary Guarantors pursuant to each Subsidiary Guaranty, dated as of October 25, 2021, by and among each Subsidiary Guarantor and the Noteholders signatory to the October SPA, subject to subsequent modifications pursuant to the Addendum, the Addendum Amendment and the NYDIG Transactions.

On July 19, 2022 and on September 13, 2022, the Company entered into an Addendum and Addendum Amendment in which adjusted the terms such as maturity date, conversion prices, and the issuance of new warrants to the Noteholders. Pursuant to the Addendum and Addendum Amendment, the Company evaluated whether the new addendums qualified as debt modification or debt extinguishment, and based on ASC 470, Debt, the Company determined the Addendum and Addendum Amendment to fall under Debt Extinguishment and the Company would be required to fair value the new debt, and in turn write off the existing debt on the books.

Following the debt extinguishment on July 19, 2022 as noted further above, the Convertible Notes will be accounted for under the fair value method on a recurring basis upon issuance (e.g., upon execution of the Addendum) per guidance within ASC 480, and at each subsequent reporting period, with changes in fair value reported in earnings. Although the Notes are not being accounted for under 825-10, the substance of the debt is considered to be the same and is therefore considered outside the scope of ASC 470-60. As such, the Company performed a fair value analysis of the Convertible Notes. For the year-ended December 31, 2023 and quarter-ended March 31, 2024, the Company had Monte Carlo simulations run-out for the expected conversion dates of the Convertible Notes using risk free rates, annual volatility, daily trading volumes, likely conversion profiles, and other assumptions based on principal and accrued interest as of the period ends. The Company determined the fair value of the Convertible Notes uses certain Level 3 inputs.

For the three months ended March 31, 2023, the Company had approximately $1.4 million of note conversions with the Noteholders, therefore reducing the outstanding principal balance to approximately $11.6 million as of March 31, 2023. The Company also performed a fair value assessment whereas the value of the convertible notes was determined to be approximately $10.4 million, resulting in a revaluation gain noted for the three months ended March 31, 2023 between the fair value of the notes as of December 31, 2022, less conversions, to fair value as of March 31, 2023. For the three months ended March 31, 2024, the Company had approximately $1.0 million of conversions with the Noteholders, therefore reducing the outstanding principal balance to approximately $7.7 million as of March 31, 2024. The Company also performed a fair value assessment on February 28, 2024 (date of the Fourth Amendment noted below) for which the fair value was determined to be approximately $7.5 million, and March 31, 2024 the fair value was determined to be approximately $6.2 million.

The following table represents the significant and subjective fair value assumptions used for Convertible Notes during the three months ended March 31, 2024:

	Three months ended March 31, 2024
Stock price	$	2.88 – 3.43
Conversion price	$	3.78
Volatility		97.5 – 115	%
Risk-free interest rate		5.31- 5.46	%

The events of default stated in the Notice of Acceleration and Repossession defined below with NYDIG Financing constituted a cross-default under the terms of secured convertible notes issued to the Noteholders. In addition to such cross-default, the failure of the Company pursuant to the Addendum dated as of July 19, 2022, to escrow an aggregate amount of $950,000 for the benefit of the Noteholders by December 21, 2022, constituted an event of default under the Notes. Due to the default, the Company accrued interest at a rate of 18% which amounted to $617 thousand as of March 10, 2023. On March 10, 2023, the Company entered into a Second Addendum Amendment with the Noteholders, in which the Company paid the accumulated default accrued interest of $617 thousand through the Company’s restricted escrow accounts and contemporaneously with the payment, the Noteholders waived all existing events of default arising under the convertible notes.

On May 11, 2023, the Company entered into a Second Amendment Agreement (the “Second Amendment”) with the holders of its October Secured Notes to extend the maturity date of the October Secured Notes to July 25, 2024. In connection with the Second Amendment, the Company paid an extension fee of $250,000 and increased the principal amount of the outstanding October Secured Notes by 14%. The Company also issued 240,000 new Class A warrants exercisable at $12.50 and 80,000 new Class B warrants exercisable at $20.00.

Subject to the Equity Conditions (as defined below), upon each trigger set forth below, the Company is allowed, once per trigger, require the Note holders to convert up to 20% percent of the outstanding amount of the October Secured Notes as:

(i)	the Company’s Common Stock trades for 10 consecutive days at or above $12.50 per share and at least 40,000 shares trade on each day.
(ii)	the Company’s Common Stock trades for 10 consecutive days at or above $17.50 per share and at least 40,000 shares trade on each day.
(iii)	the Company’s Common Stock trades for 10 consecutive days at or above $22.50 per share and at least 40,000 shares trade on each day.

The Equity Condition is met if all of the following conditions have been satisfied: (i) the shares of Common Stock issuable upon the conversion are either registered under the Securities Act of 1933 or resellable under Rule 144 thereunder without any volume restrictions, (ii) the number of shares issuable to each Note holder are below 4.99% of the outstanding shares, (iii) at least 20 trading days has elapsed since the previous mandatory conversion, (iv) the Company is current in all the SEC filings, and (v) the Company has obtained all required approvals from NASDAQ, or any successor trading market, to list the Common Stock to be issued upon such conversion.

On November 20, 2023, the Company and the Noteholders entered into a Third Amendment Agreement to amend the Notes, the October SPA and related agreements (collectively, the “Transaction Documents”). The aim is to facilitate future financings by the Company that may include funds for prepayment of the Notes by permitting the Company to force conversion of up to $1.5 million of the Notes under certain circumstances, reduce the prepayment penalty in return for reducing the conversion price of the $4.7 million of the Notes and reducing the exercise price of 150,000 of the Warrants to $0.01.

As provided in the original terms of the Notes, in the event the Company prepays the amounts owed under Notes, the Company must pay an additional 20% prepayment penalty. Under the new Transaction Documents, in the event the prepayment occurs between February 15, 2024 and July 24, 2024, prepayment penalty is reduced to 10%.

In addition, under the new Transaction Documents, the Company has the right to force the conversion of up to $1.5 million of face value of the Notes in whole or in part at any time up to the maturity date of the Notes, provided that at the time of such conversion the share price on the trading market on which the Company’s shares is then listed exceeds $5.00 and a minimum volume of 50,000 traded each trading day for the five trading days immediately prior to such forced conversion.

As consideration for the reduction in the prepayment penalty and the new forced conversion right, the Company agreed that an aggregate $4.7 million of the Notes had the conversion price reduced to $3.78 per share and 150,000 of the Warrants had the exercise price reduced to $0.01 (the “Repriced Warrants”), provided that prior to February 1, 2024, for each $31.33 in Notes converted by a Noteholder, such Noteholder may exercise one Repriced Warrant and that on February 1, 2024, all Repriced Warrants became immediately exercisable.

On February 28, 2024 the Company and the Purchasers entered into a Fourth Amendment Agreement to amend the Notes, SPA and related agreements to facilitate future financings by the Company by amending the Transaction Documents as follows:

The Company shall be permitted to undertake at-the-market transactions in the future provided:

● No Event of Default shall have occurred and be continuing under the Notes; and

● The market price of the shares of common stock shall be at least the At-the-Market (“ATM”) Floor Price. ATM Floor Price means $10 per share initially, which is reduced to $8 per share six months after the ATM is effective and $6 per share 12 months after the after the effective date of the ATM.

In addition, the Company will be permitted to unilaterally extend the maturity date of the Notes for two 3-Month extensions if prior to the then in effect maturity date the Company gives notice to the Purchasers and increases the principal amount of the Notes on the date of each such extension by two percent (2%) the principal amount of the Notes outstanding on the date of this Agreement per each extension.

In consideration of the foregoing, the Company:

● Reduced the conversion price of the Notes to $3.78 per share;

● The Purchasers received an aggregate of 850,000 three year warrants exercisable at $0.01 per share;

● An aggregate of 320,005 warrants held by the Purchasers had the exercise price reduced to $3.78 per share (the “$3.78 Warrants”); and

● An aggregate of 478,951 warrants held by the Purchasers had the exercise price reduced to $6.00 per share (the “$6.00 Repriced Warrants”). For every one $6.00 Repriced Warrant exercised by a Purchaser, such Purchaser shall receive 1.36 new five-year warrants with an exercise price of $0.01, 1.6 new five-year warrants with an exercise price of $4.20, and 1.6 new five-year warrants with an exercise price of $5.70.

The effect of the additional penny warrants, $3.78 warrants, and the $6.00 repriced warrants including additional warrants if exercised with the Noteholders, created a loss on debt extinguishment of approximately $5.8 million due to the fair value associated as of February 28, 2024. Such amounts were recorded as a loss on debt extinguishment and affected the Company’s warrant liability and additional paid in capital balance account. Due to the requirement of the shareholder approval associated with the Fourth Amendment, the warrants associated will be treated as a liability and be revalued each quarter.

Pursuant to additional agreements with holders of another 51,618 outstanding warrants, similar adjustments with those warrants, resulted in a total adjustment to 530,569 warrants. As the 51,618 warrants were not with the Noteholders, the treatment of $6.00 repriced warrants was recorded as a deemed dividend and adjusted the Company’s earnings per share calculation noted in Footnote 9. The fair value associated with the 51,618 warrants with non-Noteholders totaled approximately $386 thousand.

Because the foregoing will result in the issuance of more than 20% of the Company’s outstanding shares, it is subject to stockholder approval at the Company’s annual meeting of shareholders, to be held not later than May 30, 2024. Until such shareholder approval is obtained, the Company may not prepay any amount of the Notes which would reduce the aggregate principal amount thereof below $5 million.

On March 5, 2024, one of the Noteholders exercised 50 thousand warrants at the $6.00 repriced warrant value. As such, the Company issued 68 thousand $0.01 warrants, 80 thousand $4.20 warrants, and 80 thousand $5.70 warrants.

The following table represents the significant fair value assumptions used for warrants issued or repriced during the three months ended March 31, 2024:

	Three months ended March 31, 2024
Stock price	$	2.88- 4.07
Exercise price	$	0.01- 20.00
Expected term in years		3.00 – 8.77
Expected dividend yield		0.00	%
Volatility		127.50 – 137.50	%
Risk-free interest rate		4.28- 4.44	%

With the Fourth Amendment on February 28, 2024, a fair value was established at approximately $7.5 million. The Fourth Amendment caused a loss on extinguishment of debt of approximately $5.3 million which included a gain on revaluation of the debt of $436 thousand and warrant valuation of new $0.01 warrants, repriced $3.78 warrants and repriced $6.00 warrants with potential new $0.01, $4.20 and $5.70 additional warrants included if the $6.00 repriced warrants were exercised. This resulted in a $5.8 million loss on extinguishment of debt.

As of December 31, 2023, the fair value of the convertible debt was approximately $8.5 million outstanding which included adjustments to the value due to debt extinguishments and revaluations of multiple amendments throughout the fiscal year, as well as approximately $6.0 million in note conversions of the debt. The Company had approximately an $8.7 million principal balance outstanding for the convertible debt as of December 31, 2023. As of March 31, 2024, the fair value of the debt was approximately $6.2 million which included $1.0 million of conversions from January 1, 2024 through March 31, 2024, as well as a gain on debt for extinguishment with the Fourth Amendment on February 28, 2024 and the quarter valuation on March 31, creating a total gain on debt extinguishment and revaluation of approximately $1.3 million. In addition, a warrant revaluation was done at March 31, 2024, which created a gain on revaluation associated with the warrant liability of approximately $1.5 million.

* Due to event of default- the entire NYDIG Financing became current, see note below.

On December 30, 2021, Soluna MC Borrowing 2021-1 LLC (the “Borrower”), an indirect wholly owned subsidiary of the Company entered into a Master Equipment Finance Agreement (the “Master Agreement”) with NYDIG ABL LLC (“NYDIG”) as lender, servicer and collateral agent (the “NYDIG facility”). The Master Agreement outlined the framework for a financing up to approximately $14.4 million in aggregate equipment financing. Subsequently, the parties negotiated the specific terms of each equipment financing transaction as well as the terms upon which the Noteholders would consent to the transactions contemplated by the Master Agreement.

On January 14, 2022, the Borrower effected an initial drawdown under the Master Agreement in the aggregate principal amount of approximately $4.6 million that bore interest at 14% and was to be repaid over 24 months. On January 26, 2022, the Borrower had a subsequent drawdown of $9.8 million. As part of the transactions contemplated under the Master Agreement, (i) the Company’s indirect wholly owned subsidiary, Soluna MC LLC, formerly EcoChain Block LLC (“Guarantor”), which is the owner of 100% of the equity interests of Borrower, executed a Guaranty Agreement in favor of NYDIG, as lender, dated as of December 30, 2021 (the “Guaranty Agreement”), (ii) Borrower has granted a lien on, and security interest in, all of its assets to NYDIG, as collateral agent, (iii) Guarantor entered into an equipment financing arrangement on assets purchased with the borrowed funds, (iv) Borrower would borrow from NYDIG the loans as forth in certain loan schedules (the “Specified Loans”), and (v) Borrower had executed a Digital Asset Account Control Agreement (the “ACA Wallet Agreement”) with NYDIG, as collateral agent and secured party, and NYDIG Trust Company LLC, as custodian, dated as of December 30, 2021, as well as such other agreements related to the foregoing as mutually agreed (collectively, the “NYDIG Transactions”).

In connection with the NYDIG Transactions, on January 13, 2022, the Company entered into a Consent and Waiver Agreement, dated as of January 13, 2022 (the “Consent”), with the Noteholders, in connection with the October SPA, pursuant to which the Noteholders agreed to waive any lien on, and security interest in, certain assets, provided various contingencies are fulfilled, and each Noteholder who acquired October Secured Notes having a principal amount of not less than $3,000,000 agreed to waive its rights under Section 4.17 of the October SPA to participate in Subsequent Financings (as defined in the October SPA) with respect to the NYDIG Transactions and any additional loans under the MEFA that only finance the purchase of equipment from NYDIG, in order to consent to the NYDIG Transactions. Pursuant to the Consent, the Noteholders also waived the current requirement of the October SPA and the other transaction documents (collectively, the “SPA Documents”) that the Borrower become an Additional Debtor (as defined in the Security Agreement) and execute an Additional Debtor Joinder (as defined in the Security Agreement) for so long as the Specified Loans were outstanding, and NYDIG would not have entered into a subordination or intercreditor agreement with respect to the Guaranty. Further, pursuant to the Consent, the Noteholders waived the right to accelerate the Maturity Date of the October Secured Notes and the right to charge a default rate of interest on such Notes, in each case, with respect to certain changes in names of, and jurisdiction of incorporation, of the Debtors (as defined in the SPA Documents), which waiver would not waive any other Event of Default (as defined in any of the SPA Documents), known or unknown, as of the date of Consent.

Promptly after the date of the Consent, the Company issued warrants to purchase up to 3,400 shares of common stock to the Noteholder holding the largest outstanding principal amount of October Secured Notes as of the date of the Consent. Such warrants were substantially in form similar to the other warrants held by the Noteholders. Such warrants were exercisable for three years from the date of the Consent at an exercise price of $237.50 per share. On December 5, 2022, the exercise price of the warrants was reduced to an exercise price of $19.00 per share, effective with the closing of the Securities Purchase Agreement Offering on December 5, 2022.

The Company, through the Borrower, was required to make average monthly principal and interest payments to NYDIG of approximately $730 thousand on initial drawdown in aggregate principal amount of approximately $4.6 million bearing interest at 14%, and a subsequent drawdown of $9.8 million.

On December 20, 2022, the Borrower received a Notice of Acceleration and Repossession (the “NYDIG Notice”) from NYDIG with respect to the Master Agreement, by and between Borrower and NYDIG. The obligations of Borrower under the Master Agreement and reflected in the NYDIG Notice are ring-fenced to Borrower and its direct parent company, Soluna MC LLC. The Company is not a party to any guaranty, collateral agreement or other support agreement with or for the benefit of NYDIG.

The NYDIG Notice states that (a) Borrower failed to observe or perform certain covenants, conditions or agreements contained in the Master Agreement and such failure continued unremedied for a period of ten days after Borrower’s knowledge of such breach, which resulted in an event of default under the Master Agreement, and (b) Borrower defaulted under the guaranty, collateral agreement, or other support agreement, which resulted in an event of default under the Master Agreement. In addition, the NYDIG Notice states that Borrower failed to pay certain payments of principal and interest under the Master Agreement when due, which failure also constituted an event of default under the Master Agreement. As a result of the foregoing events of default, and pursuant to the Master Agreement, NYDIG (x) declared the principal amount of all loans due and owing under the Master Agreement and all accompanying Loan Documents (as defined in the Master Agreement) to be due and immediately payable, (y) imposed a default rate of interest on any outstanding principal amount of each loan (together with all then unpaid interest accruing thereon) and all other obligations under the Master Agreement and the Loan Documents, and (z) demanded the return of all equipment subject to the Master Agreement and the Loan Documents. As such, the principal balance of $10.5 million became due immediately and the Borrower was to bear interest, at a rate per annum equal to 2.0% plus the rate per annum otherwise applicable to such obligations set forth in the Master Agreement. Also, as the Company was not able to obtain a waiver, the outstanding deferred financing costs were written off. As of December 31, 2022, the Borrower had incurred accrued interest and penalty of approximately $274 thousand. On February 23, 2023, NYDIG proceeded to foreclose on all of the collateral securing the MEFA, and repossessed the collateralized assets that totaled approximately $3.4 million, in which approximately $560 thousand was first used to pay off accrued interest and penalty to date. On September 5, 2023, NYDIG provided a letter finalizing the accounting for the repossessed collateralized assets totaling proceeds of approximately $3.4 million. This included legal and other expenses associated with the sale of the assets net a modest gain on the estimated net book value of the assets totaling $251 thousand that was expensed as a loss on disposition of assets for the year ended December 31, 2023. On December 7, 2023, NYDIG filed its Motion for Summary Judgment seeking entry of a judgment against Soluna in the approximate amount of $10.3 million for principal and interest and penalties. On January 12, 2024, Soluna filed its objection to NYDIG’s motion for summary judgment on the grounds that NYDIG failed to explain what collateral of which loan was sold and how the sale proceeds were allocated to each loan. A summary judgment motion was performed on February 13, 2024, and was agreed upon by both NYDIG and the Borrower, that the total outstanding loan principal balance would be approximately $9.2 million, in which a penalty fee was applied of approximately $1.0 million to the repossessed collateralized assets, and outstanding interest and penalty balance would be approximately $936 thousand as of December 31, 2023. The Company applied the per diem interest rate agreed upon with the summary judgement for the three months ended March 31, 2024 and recorded interest expense of approximately $363 thousand and has an outstanding interest and penalty accrual of approximately $1.2 million recorded within “Accrued Liabilities” as of March 31, 2024. See Note 10 for further information in relation to the NYDIG litigation matter.

On May 9, 2023, DVCC and Navitas West Texas Investments SPV, LLC entered into a 2-year Loan Agreement (“Term Loan”) for $2,050,000. The unpaid principal balance of the Term Loan shall bear interest at per annum rate equal to 15%. Beginning on the last Business Day of the month in which the In-Service Date occurs (date Dorothy 1B is put into full operation following the planned ramp-up period), and continuing on the last Business Day of each month thereafter until the repayment of all Term Loan debt principal and accrued interest occurs, DVCC shall make debt service payments on the Term Loan through a cash sweep with the Site-level Free Cash Flow (total revenue of DVCC minus power costs and site level costs listed in Loan and Security agreement), otherwise to be distributed to Soluna Holdings, Inc., the ultimate parent entity of DVCC (the “SLNH Cash”) being applied as a permanent repayment of the Loan in an amount equal to the greater of: (i) the sum of (A) the amount of accrued and unpaid interest that has not yet been added to the principal balance of the Term Loan, if any, plus (B) an amount equal to 1/24th of the then outstanding principal balance of the Term Loan; provided that the aggregate amount payable pursuant to this clause (i) shall not exceed SLNH Cash times 0.60; or (ii) SLNH Cash times 0.33.

Any and all monthly debt service amounts so paid to Lender shall be applied first to accrued and unpaid interest that has not yet been added to the principal balance of the Term Loan, if any, and then to repayment of the then outstanding principal balance of the Term Loan. On the Term Loan Maturity Date (May 9, 2025), all remaining principal and accrued and unpaid interest that has not yet been added to the principal balance of the Term Loan, if any, shall become immediately due and owing in full and shall be paid by wire transfer in immediately available funds. As of March 31, 2024 and December 31, 2023, approximately $1.1 million and $1.7 million is included in current portion of debt as the Company’s expectation is that principal and capitalized interest payments will be made to pay off the Term Loan within one year after quarter or year-end. The Company has paid approximately $616 thousand in principal for the three months ended March 31, 2024 and $547 thousand in principal and capitalized interest payments for the year ended December 31, 2023. Interest expense related to the Navitas Term Loan for the three months ended March 31, 2024 was approximately $63 thousand.

Line of Credit

On September 15, 2021, the Company entered into a $1.0 million unsecured line of credit with KeyBank National Association (“KeyBank”), that will, among other things, allow the Company to request loans and to use the proceeds of such loans for working capital and other general corporate purposes (the “KeyBank facility”). The line of credit bears interest at a rate of Prime + 0.75% per annum. Accrued interest is due monthly and principal is due in full following KeyBank’s demand. As of January 1, 2023, the Company had drawn on the line of credit and approximately $350 thousand of the amount drawn under the line of credit remained outstanding. As of December 31, 2023, the remaining $350 thousand had been paid down. The Company does not have any remaining balance outstanding as of December 31, 2023 and March 31, 2024. The Company does not plan to draw down on the line of credit in the foreseeable future. In addition, future drawdowns require pre-approval by KeyBank.
