Rhea-AI Filing Summary

Soluna Holdings, through its subsidiary Soluna Digital, acquired all membership interests in the Dorothy 1A wind-powered bitcoin data center project in Silverton, Texas. It paid $6.0 million at closing and owes an additional $10.5 million by July 1, 2026.

To help fund the deal, the company entered into a financing with YA II PN, LTD. for an unsecured Promissory Note of up to $12,000,000, maturing on May 15, 2027 at a 5% interest rate, rising to 18% on default. The note requires monthly payments of $1.2 million plus a 5% principal premium and must be partially redeemed if the company completes certain larger financings.

In a related private placement, Soluna issued a warrant to the lender to purchase up to 2,400,000 common shares at $1.06 per share, exercisable immediately for 12 months, subject to a beneficial ownership cap initially set at 4.99%, adjustable up to 9.99%.

Insights

Soluna adds project ownership using structured debt and warrant financing.

Soluna now fully owns the Dorothy 1A wind-powered data center by buying an additional 85.4% Class B interest for staged cash payments totaling $16.5 million. Control over a dedicated hosting campus can simplify operations but also concentrates exposure to this single asset.

The unsecured Promissory Note of up to $12,000,000 adds leverage with a relatively low 5% base rate but a steep 18% default rate and required $1.2 million monthly amortization plus premiums. A forced partial redemption tied to future financings above $20 million may influence how Soluna structures additional capital raises.

The 2,400,000-share warrant at $1.06 with a short 12‑month term introduces potential equity issuance but includes a 4.99%–9.99% beneficial ownership cap and cashless exercise mechanics if no registration is available. Actual dilution will depend on future share price and the lender’s exercise decisions.

Membership Interests Purchase Agreement financial
"entered into a Membership Interests Purchase Agreement (the “MIPA”), with Soluna SLC"
Promissory Note financial
"issued to the Lender a Promissory Note (the “Note”) payable to the Lender"
A promissory note is a written IOU in which one party promises to pay a specific sum, often with interest, to another party by a set date or on demand. Investors care because it functions like a loan: it creates a legal claim on future cash flows, carries credit and timing risk, and can affect valuation or liquidity—think of it as a formal, tradable promise to be repaid that can be assessed like any other debt investment.
Amortization Payments financial
"required to make monthly payments (“Amortization Payments”) of $1.2 million per month"
Regular payments that combine principal and interest to gradually reduce a loan or other debt over a set period, similar to how a mortgage payment chips away at what you owe until the balance is zero. For investors, these payments affect a company’s cash flow and interest costs, changing how much free cash is available for dividends, reinvestment, or growth and influencing credit risk and valuation.
Event of Default financial
"increase to a rate per annum of 18% upon the occurrence of an Event of Default"
An event of default is a specific breach of a loan or bond agreement—such as missed payments or breaking agreed rules—that gives lenders the legal right to act, for example by demanding immediate repayment, seizing collateral, or accelerating other obligations. For investors, it’s a red flag because it can sharply reduce a company’s ability to operate or raise money, like a car lender repossessing a vehicle after missed payments, and often leads to falling share or bond prices.
cashless exercise financial
"then the Warrant may also be exercised, in whole or in part, at such time by means of a cashless exercise"
A cashless exercise is a way for an option holder to convert stock options into actual shares without paying the purchase price in cash; instead they immediately give up a portion of the newly issued shares to cover the cost and any withholding taxes. Investors care because this process increases the number of shares available and can slightly dilute existing holdings, while also signaling how insiders or employees are realizing compensation without needing cash — similar to paying for a purchase by handing over part of what you just bought.
beneficially own in excess of 4.99% financial
"The Lender does not have the right to exercise any portion of the Warrant if the Lender, together with its affiliates, would beneficially own in excess of 4.99%"

Item 1.01. Entry into a Material Definitive Agreement.

 

Membership Interests Purchase Agreement

 

On April 15, 2026, Soluna Digital Inc. (the “Purchaser”), a wholly owned subsidiary of Soluna Holdings, Inc. (the “Company”), entered into a Membership Interests Purchase Agreement (the “MIPA”), with Soluna SLC Fund I Projects Holdco LLC (the “Seller”) and Soluna DVSL JVCo, LLC, a Delaware limited liability company (the “Dorothy 1A Project Company”), pursuant to which the Purchaser acquired 85.4% of the issued and outstanding Class B Membership Interests in the Dorothy 1A Project Company from the Seller. The Dorothy 1A Project Company owns a wind-powered data center campus in Silverton, Texas focused on bitcoin hosting. The MIPA contains customary representations and warranties of the Seller and the Purchaser.

 

The closing of the acquisition (the “Closing”) occurred simultaneously with the execution of the MIPA on April 15, 2026. At the Closing, the Purchaser paid $6.0 million to the Seller and an additional $10.5 million payment is due to the Seller no later than July 1, 2026. Upon the Closing, the Purchaser owns 100% of the issued and outstanding membership interests of the Dorothy 1A Project Company.

 

Securities Purchase Agreement and Promissory Note

 

In connection with the MIPA, on April 15, 2026, the Company entered into a Securities Purchase Agreement (the “SPA”) with YA II PN, LTD. (the “Lender”), pursuant to which the Company issued to the Lender a Promissory Note (the “Note”) payable to the Lender, providing for an unsecured loan in the aggregate principal amount of up to $12,000,000 (the “Principal Amount”). The outstanding Principal Amount will mature on May 15, 2027 (the “Maturity Date”) and bears interest at a rate per annum of 5%, based on a 365-day year, which interest rate shall increase to a rate per annum of 18% upon the occurrence of an Event of Default (as defined in the Note) for so long as such event remains uncured. Under the Note, the Company is required to make monthly payments (“Amortization Payments”) of $1.2 million per month, beginning sixty (60) days after closing until the Note is repaid in full. Each Amortization Payment shall include a 5% premium of the principal amount of such payment.

 

The Company may, upon at least one Business Day’s prior written notice to the Lender, prepay the outstanding Principal Amount and an additional 5% of such Principal Amount (solely in respect of a redemption in full), and any accrued and unpaid interest, at any time prior to the Maturity Date. If the Company consummates a financing transaction, or series of financing transactions within a thirty (30) day period, with aggregate gross proceeds in excess of $20 million (excluding any (i) transaction with the Lender or its affiliates, (ii) sales under the At the Market Offering Agreement entered into between the Company and H.C. Wainwright & Co., LLC on April 29, 2025, (iii) issuance under the Standby Equity Purchase Agreement entered into between the Company and the Lender on August 12, 2024 or the Standby Equity Purchase Agreement entered into between the Company and the Lender on March 24, 2026, or (iv) exercises of options, warrants, or convertible securities outstanding as of April 15, 2026), then, unless waived by the Lender, the Company shall be required to redeem the Note in an amount equal to (a) 20% of the outstanding Principal Amount and (b) all accrued and unpaid interest on the Note.

 

The Note includes customary representations, warranties and covenants and sets forth certain events of default after which the outstanding Principal Amount may be declared immediately due and payable and sets forth certain types of bankruptcy or insolvency events of default involving the Company after which the outstanding Principal Amount becomes automatically due and payable.

 

Guaranty

 

Pursuant to the SPA, Soluna Wind Holding, Inc., a wholly owned subsidiary of the Company (the “Guarantor”), entered into a Guaranty, dated April 15, 2026 (the “Guaranty”). Pursuant to the terms of the Guaranty, the Guarantor agreed to guarantee the complete performance and fulfillment of the Company’s obligations under the SPA and the Note.

 

 
 

 

Private Placement

 

Pursuant to the SPA, the Company issued to the Lender in a private placement (the “Private Placement”) a common warrant (the “Warrant”) to purchase up to 2,400,000 shares of common stock of the Company, par value $0.001 per share (the “Common Stock”).

 

The Warrant issued to the Lender in the Private Placement was issued and sold without registration under the Securities Act of 1933, as amended (the “Securities Act”), or state securities laws in reliance on the exemptions provided by Section 4(a)(2) of the Securities Act promulgated thereunder and in reliance on similar exemptions under applicable state laws.

 

The Warrant has an exercise price of $1.06 per share of Common Stock, is exercisable upon issuance and expires on the twelve-month anniversary of its date of issuance. The Warrant is exercisable, at the option of the Lender, in whole or in part by delivering to the Company a duly executed exercise notice and, at any time a registration statement registering the resale or other disposition of the shares of Common Stock underlying the Warrant under the Securities Act is effective and available for such shares, or an exemption from registration under the Securities Act is available for such shares, by payment in full in immediately available funds for the number of shares of Common Stock purchased upon such exercise. If at the time of exercise more than six months after the issuance date there is no effective registration statement registering, or the prospectus contained therein is not available for the resale or other disposition of the shares of Common Stock underlying the Warrant, then the Warrant may also be exercised, in whole or in part, at such time by means of a cashless exercise, in which case the Lender would receive upon such exercise the net number of shares of Common Stock determined according to the formula set forth in the Warrant.

 

The Lender does not have the right to exercise any portion of the Warrant if the Lender, together with its affiliates, would beneficially own in excess of 4.99% of the number of shares of Common Stock outstanding immediately after giving effect to such exercise. The Lender may increase or decrease the beneficial ownership limitation up to 9.99%, provided, however, that any increase in the beneficial ownership limitation shall not be effective until 61 days following notice of such change to the Company.
