Soluna Holdings filed an 8-K to share a January 2026 business update and attach a detailed press release. The company is advancing several renewable-powered computing projects and expanding from Bitcoin-focused hosting into AI and high‑performance computing.
At Project Kati 1 (83 MW under construction), Soluna obtained ERCOT energization approval and began power commissioning for the 24 MW K1A Galaxy Phase 1, targeting completion in February, with additional 12 MW phases aiming to start commissioning in March and April. A new partnership will pilot Cormint’s proprietary container design at K1B, with equipment delivery expected in Q2.
For Project Kati 2, Soluna announced a joint venture with Metrobloks and is engineering a 350 MW Tier 3 AI campus across seven buildings, supported by over 500 acres of additional land. The company launched an RFP to 10 construction management firms and is negotiating with three potential single‑tenants to pre‑lease the full campus. Other updates include a 20 MW fleet upgrade underway at Project Dorothy 1A, winter‑storm‑driven curtailment at certain Bitcoin sites, advancing PPAs and land acquisition in its pipeline, and the planned appointment of Michael Picchi as Chief Financial Officer effective April 1, 2026.
Soluna Holdings, Inc. received a large shareholder disclosure from investor Robert L. Bugbee, who reported beneficial ownership of 9,168,000 shares of common stock, representing 9.3% of the class as of February 6, 2026.
Bugbee reports sole voting and sole dispositive power over all 9,168,000 shares, with no shared voting or dispositive authority. He also certifies that the shares were not acquired to change or influence control of Soluna Holdings and that he is not part of any group with respect to this investment.
Soluna Holdings, Inc. reported that it has received ERCOT approval to begin initial energizing and phased commissioning of its Project Kati 1 data center campus in South Texas. Project Kati 1 is an 83 MW wind-powered Bitcoin mining facility that is expected to increase Soluna’s total capacity by more than 67%.
The project is split into Kati 1A at 48 MW, targeted to be fully ramped by early Q2, and Kati 1B at 35 MW, expected to be completed by the end of Q3 and reaching overall completion in Q4. Kati 1B includes a 12 MW deployment with Cormint using eight modular data center units.
Soluna estimates anticipated annual revenue of $17.3–$19.6 million from Project Kati 1 and projects hashrate capacity of 3.5 EH/s, using wind power from the Las Majadas project to support large-scale Bitcoin mining and other intensive computing workloads.
Soluna Holdings, Inc. entered into an Equipment Supply Agreement with Cormint Data Systems, a Texas-based data center infrastructure firm. The agreement supports a planned 12 MW deployment at Soluna’s Project Kati 1 site in Willacy County, Texas. Cormint has previously designed, delivered, and operated more than 130 MW of data center infrastructure, indicating substantial experience in large-scale deployments. The company disclosed this arrangement via a press release furnished under Regulation FD, which is attached as an exhibit and not treated as filed for liability purposes.
Soluna Holdings, Inc. reported a planned leadership transition in its finance organization. The company will accept interim CFO and Treasurer David Michaels’ resignation once a new CFO is in place, noting his decision was not due to any disagreement over operations, policies, or practices.
On January 19, 2026, Soluna appointed Michael Picchi as CFO and Treasurer, effective April 1, 2026. He will join on March 9, 2026 as Head of Finance. His offer provides a $375,000 annual base salary, a target annual bonus equal to 50% of base salary, and a contemplated grant of 1,281,850 RSUs subject to time-based vesting. If terminated without cause or if he resigns for good reason, he is eligible for six months of base salary, certain earned bonuses, partial RSU vesting, and up to six months of COBRA premium support, subject to a release of claims.
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. reported that it has scheduled the groundbreaking of Project Kati, described as the company’s largest facility to date.
The company communicated this milestone through a press release dated September 11, 2025, which is furnished as an exhibit under a Regulation FD disclosure and is not treated as filed for liability purposes under federal securities laws.
