The company had previously been notified that it was out of compliance and had until November 4, 2025 to cure the deficiency. A press release dated October 6, 2025, announcing that compliance was regained on October 2, 2025, is included as an exhibit to this report.

The filing lists security ownership for directors and officers: all current directors and executive officers (9 persons) hold 6,447,886 shares, or 10.1% of the outstanding stock. Individual holdings shown include Michael Toporek: 1,221,700 shares (1.9%). Institutional ownership disclosed includes Generate Strategic Credit Master Fund I-B, L.P.: 3,345,829 shares (5.0%).

Soluna Holdings, Inc. reported that its subsidiaries Soluna MC Borrowing LLC 2021-1 and Soluna MC LLC entered into a Settlement Agreement with NYDIG ABL LLC on September 29, 2025. This agreement fully settles and resolves a previously agreed judgment under which the Soluna parties were jointly and severally liable for $9,182,646.13 plus interest related to NYDIG equipment finance loans. In return for making settlement payments, NYDIG agreed to release Soluna and its affiliates from all claims relating to the loans, although the full judgment can be revived if Soluna misses required payments or other defaults occur.

Soluna Holdings, Inc. (SLNH) disclosed management and security-holder details in this S-3 filing. The company stated that following Mr. Tunison's resignation, director David C. Michaels was appointed interim Chief Financial Officer and Treasurer effective August 21, 2025. The filing identifies Generate Strategic Credit Master Fund I-B, L.P. as the record holder of certain Warrants and describes related entities that may be deemed to share beneficial ownership of those Warrants. The number of shares issuable on exercise is not presently known and exercise is subject to a 9.99% beneficial ownership limitation, which prevents the holder from exercising Warrants that would cause ownership above that cap. The document also lists certain related SEC filings and exhibits and provides a fee breakdown showing $20,000 legal fees, $5,000 accounting fees, $2,000 miscellaneous, and a total indicated of $28,013.53. Signatures include the CEO John Belizaire and interim CFO David C. Michaels.
Soluna Holdings, Inc. filed a prospectus supplement for an at-the-market offering of its common stock with an aggregate offering price of up to $87,650,000. The offering is being made under an existing At the Market Offering Agreement dated April 29, 2025 with H.C. Wainwright & Co., LLC, using a previously filed Form S-3 shelf registration and related ATM prospectus.
The company states that this new supplement must be read together with its prior ATM prospectus documents. Soluna has already sold 13,680,483 shares of common stock for aggregate gross proceeds of approximately $12.3 million under the same Sales Agreement. A legal opinion from Brownstein Hyatt Farber Schreck, LLP regarding the validity of the shares is included as an exhibit.
The company is updating its at-the-market common stock offering of up to $87,650,000 under its existing S-3 shelf. The supplement reports that, as of September 23, 2025, its public float was $98.5 million, based on 47,036,233 shares held by non-affiliates at a price of $2.10 per share, so it is no longer subject to the Form S-3 General Instruction I.B.6 sales limitations for this program.
At a reference price of $2.10 per share, fully using the $87,650,000 capacity would mean issuing about 41.7 million shares, but as of September 22, 2025 the company had approximately 4.3 million shares of common stock authorized and available for future issuance, which constrains how many shares can currently be sold under the Sales Agreement.
Generate Strategic Credit Master Fund I-B, L.P. and three affiliated entities jointly filed a Schedule 13G reporting shared beneficial ownership of 3,345,829 shares of Soluna Holdings, Inc. common stock, representing 9.99% of the class on a post-exercise basis. The shares are issuable upon exercise of warrants held by Generate Master Fund; a beneficial ownership limitation of 9.99% caps additional issuance and excludes 654,171 shares from this filing. The reporting group is organized in Delaware and states the filing is not an admission of beneficial ownership under Sections 13(d)/(g).
Soluna Holdings, Inc. entered into a new senior secured Credit and Guaranty Agreement providing term loan commitments of up to $35.5 million, split among Tranche A-1, Tranche A-3, and Tranche B, and allowing up to an additional $64.5 million in future project-level loans. The company’s subsidiaries initially borrowed $12,623,591 to fund its Dorothy 1A, Dorothy 2, and Kati data center projects, with loans maturing no later than September 12, 2030.
Loans bear interest at Term SOFR plus 10.0% or ABR plus 9.0%, with a SOFR floor of 3.50% and a 1.00% commitment fee on undrawn Tranche B and additional tranches. The facility is secured by first-priority liens on substantially all borrower and guarantor assets and includes financial covenants requiring a minimum trailing debt service coverage ratio of 1.60:1.00 and a minimum forward contracted ratio of 1.20:1.00.
In a related private placement, Soluna issued a pre-funded warrant to buy up to 2,000,000 common shares at an exercise price of $0.0001 per share and a common warrant to buy up to 2,000,000 common shares at $1.18 per share, each with a five-year term and a 9.99% beneficial ownership cap. The company also granted registration rights for the warrant shares and gave an affiliate of the lender a non-voting board observer right while commitments remain outstanding.
