Soluna Holdings, Inc. 8-K Filings

Soluna Holdings, Inc. (SLNH) disclosed that ERCOT has conditionally classified the 100 MW Project Dorothy campus as Base Load in Batch Zero, preserving its studied interconnection capacity and exempting it from further reliability evaluation or megawatt allocation within that study. This follows a prior conditional Base Load position for the full 166 MW at Project Kati, bringing the conditionally classified Base Load capacity across both Texas campuses to 266 MW. Soluna has also submitted a 50 MW load interconnection request for additional capacity at the Dorothy site, which is being studied directly by the transmission and distribution provider. Project Dorothy is a 100 MW wind-powered campus in Briscoe County, Texas, built behind the meter at the 150 MW Briscoe Wind Farm, and Dorothy 1 and 2 account for 98 MW of energized capacity. Soluna reports total operating capacity of approximately 206 MW and a development pipeline of about 6.3 GW, while participating in ERCOT’s ongoing verification process for the conditional classifications.

Soluna Holdings, Inc. (SLNH) reported that Chief Executive Officer John Belizaire will participate in the H.C. Wainwright 28th Annual Global Investment Conference under a Regulation FD communication. The company furnished a press release as Exhibit 99.1 describing his appearance on a panel about digital infrastructure for AI and Bitcoin.

The conference will be held in New York from September 14–16, 2026, and Belizaire is scheduled to join a panel titled “Powering The AI Boom & Bitcoin Network: The Digital Infrastructure Companies Leading the Charge” on September 14, 2026 at 2:00 PM ET. The information furnished is not deemed filed under the Exchange Act.

Soluna Holdings, Inc. (SLNH) reports two key milestones at its Project Kati campus in Willacy County, Texas. The company energized the final 14 MW at Project Kati 1, completing the 83 MW first-phase site, and now has total operating capacity of about 206 MW.

ERCOT has conditionally classified the full 166 MW Kati campus as Base Load in its Batch Zero interconnection process, covering both Kati 1 and the planned Kati 2 AI expansion. Soluna also highlights a development pipeline of about 6.3 GW, including more than 650 MW of AI and high-performance computing capacity in development at Kati 2 and Project Dorothy 3.

Soluna Holdings, Inc. (SLNH) reported that one of its subsidiaries entered into a co-mining agreement with Dory Creek, LLC, a wholly owned subsidiary of Bitdeer Technologies Group. Under this agreement, Bitdeer will deploy about 28 MW of Bitcoin mining equipment, representing roughly 1.93 EH/s of hash rate, at Soluna’s wind-powered Project Kati 1 data center in South Texas. Deployment is expected to begin in September 2026 and ramp in batches. Project Kati 1 is described as an 83 MW site, contributing to Soluna’s total of 192 MW of operating data center capacity and a development pipeline of 6.3 GW across projects in various stages.

Soluna Holdings, Inc. (SLNH) announced that it has closed the purchase of 397 acres in Briscoe County, Texas. The site will host Project Dorothy 3, a planned renewable-first AI computing campus with potential capacity of up to 300 MW.

The newly acquired land sits adjacent to Soluna’s existing Projects Dorothy 1 and 2 and to the 150 MW Briscoe Wind Farm, which the company acquired in April. The wind farm’s substation is directly across from the property, positioning Dorothy 3 for direct, behind-the-meter access to power that Soluna owns.

Soluna states that the 397 acres exceeds the 300 acres originally identified for the campus, giving room to add data halls if additional generation or storage becomes available. Project Dorothy 3 is part of a development pipeline of approximately 6.3 GW, and Soluna currently operates about 192 MW of energized capacity.

Soluna Holdings, Inc., a developer of green data centers for Bitcoin mining and AI, reported strong top-line growth but continued losses for the quarter ended June 30, 2026. Q2 2026 revenue was $15,060 thousand, a 145% year-over-year increase, driven mainly by data hosting and new wind energy generation revenue. This marked the company’s fifth consecutive quarter of sequential revenue growth.

Despite the revenue expansion, profitability remained negative. Soluna recorded an operating loss of $16,943 thousand and a net loss attributable to Soluna of $20,709 thousand in Q2, with significant general and administrative expenses and interest costs. EBITDA and Adjusted EBITDA were also negative, though Adjusted EBITDA improved relative to EBITDA after adding back non-cash items such as stock-based compensation.

Operationally, management highlighted a development pipeline of approximately 6.3 gigawatts, including the Dorothy 3 campus at 300 megawatts and 583 megawatts of additional AI-focused sites. Soluna completed vertical integration at its flagship Dorothy 1 project and formed a Kati 2 AI joint venture with Metrobloks. On the balance sheet, cash was $113,364 thousand and total assets were $293,514 thousand as of June 30, 2026, supported by substantial equity and debt financing activity.

Soluna Holdings, Inc. has formally eliminated its Series B Convertible Preferred Stock from its capital structure. Earlier in 2026, all 62,500 issued and outstanding Series B preferred shares were converted into 6,510,416 shares of common stock, and accrued dividends of $2.1 million were paid at full conversion.

On June 23, 2026, the company filed a Withdrawal of Designation in Nevada, terminating the Series B preferred designation. The filing became effective immediately, removed the prior Certificate of Designation from the Articles of Incorporation, and confirms that no Series B preferred shares remain outstanding.

Soluna Holdings, Inc. filed an amended current report to add detailed financial information for its acquisition of Briscoe Wind Farm, LLC and related pro forma results. The company acquired 100% of Briscoe for total cash consideration of approximately $55.9 million, including settlement of pre-existing obligations.

Briscoe operates a 150 MW wind project in Texas and generated 2025 revenue of $8,950,927 but recorded a net loss of $14,773,838. As part of the transaction, Soluna amended its credit agreement to create a $12.5 million Tranche C loan and issued a pre-funded warrant for 700,000 shares plus common warrants for up to 2,000,000 additional shares.

The unaudited pro forma condensed combined statements treat the acquisition as if it occurred on January 1, 2025. On this basis, combined 2025 revenue would have been $35,081,000 and net loss attributable to Soluna $54,129,000, or $1.82 per basic and diluted share on 29,748,848 weighted-average shares.

Soluna Holdings entered a joint venture with a Metrobloks-managed affiliate to develop Project Kati 2, a multi-phase data center campus in Willacy County, Texas. Soluna’s subsidiary manages the venture, holds the Class A interests, and contributed the Phase I property, a Phase II purchase agreement, and about $3.5 million of operating expenses.

Subject to closing the land purchase, Soluna committed roughly $19.0 million to acquire the Phase II property and up to $2.0 million for additional operating costs. After its capital is repaid, plus a 14% IRR and $100,000 per Gross PPA MW of Kati 2, future distributions will be split 50/50 with the Metrobloks member.

A related business update highlights steady operations at Kati 1, completed repairs and hosting deployments at Project Dorothy, progress on AI/HPC projects Kati 2, Dorothy 3, and Grace, and continued integration of the 150 MW Briscoe Wind Farm asset.

Soluna Holdings, Inc. completed the acquisition of the remaining 49% equity interest in Project Dorothy 1B for approximately $8.8 million, giving it 100% ownership of the proprietary bitcoin mining project in Silverton, Texas. The deal, executed through subsidiary Soluna Digital, Inc. on May 19, 2026, follows the earlier $53 million purchase of the Briscoe Wind Farm and the $16.5 million acquisition of Project Dorothy 1A.

With Briscoe supplying 150 megawatts of renewable power and full equity control of both D1A and D1B, Soluna now owns the entire 50 MW Project Dorothy 1 campus. The company highlights that this unencumbered ownership is a prerequisite for converting the campus to AI and high‑performance computing workloads and for marketing its next-phase AI development, Dorothy 3. Soluna also notes a development pipeline exceeding 4.3 gigawatts, including more than 1 gigawatt in development, construction, and operations.

Soluna Holdings reported strong Q1 2026 revenue growth but significantly higher losses. Total revenue rose to $9.4M, up 58% year-over-year, driven mainly by data hosting revenue of $6.7M, while cryptocurrency mining revenue declined to $2.2M.

The company posted a net loss of $17.9M versus $7.4M a year earlier, as total general and administrative expenses more than doubled to $18.5M, including $10.2M of stock-based compensation. Adjusted EBITDA remained negative at $(2.1)M, slightly worse than $(1.6)M in Q1 2025.

Soluna ended March 31, 2026 with total assets of $190.4M, cash of $68.6M and restricted cash of $17.4M. Management highlighted ongoing growth projects, including Kati 1, Kati 2 AI expansion, and the Dorothy sites, as key drivers for future computing and hosting capacity.

Soluna Holdings, Inc. provided an April 2026 business update on its Bitcoin mining and AI-focused data center projects. The company reported continued progress at its Texas sites, including Project Dorothy and Project Kati, which combine hosting services with proprietary Bitcoin prop-mining.

At Project Dorothy 1B, Soluna is consolidating prop mining after signing a hosting agreement with Saz Mining, planning 6 modular data centers (MDCs) for hosting and 16 MDCs for prop mining. Project Kati 1’s K1A Galaxy 48 MW segment operated steadily in April, while construction of the 35 MW K1B phase reached mechanical completion and began power commissioning.

Project Kati 2 and Project Dorothy 3, each targeting 300+ MW for AI and high-performance computing hosting, advanced design, interconnection, land, and tax processes. Customer activity included a 3 MW Bitcoin mining operation with Sazmining at Dorothy 1B and a fourth expansion with Blockware Solutions, taking that relationship above 17 MW of total capacity.

Soluna Holdings, Inc. reports that it has regained compliance with Nasdaq’s minimum bid price requirement for continued listing on the Nasdaq Capital Market. The company’s shares maintained a closing bid price of at least $1.00 per share from April 14, 2026, through April 29, 2026, leading Nasdaq to close the matter on April 30, 2026. Soluna states it is now in full compliance with all Nasdaq continued listing requirements, and its common stock continues to trade under the ticker SLNH.

Soluna Holdings, Inc. filed a current report describing a new partnership with Sazmining, a Bitcoin Mining as a Service provider. Sazmining will launch its second U.S. mining operation with an initial 3 MW deployment at Soluna’s Project Dorothy 1B facility in West Texas.

Project Dorothy is powered by the 150 MW Briscoe Wind Farm, which Soluna recently acquired as part of its vertical integration strategy combining renewable power and computing infrastructure. Soluna also highlights a planned third phase at the Dorothy campus that it expects could provide up to 300 MW of compute capacity for AI workloads.

Soluna Holdings, Inc. furnished an update on its partnership with Blockware, highlighting a new 3.3 MW capacity agreement at its Project Dorothy 1B data center in West Texas. This is Blockware’s first deployment at Dorothy 1B and its fourth expansion with Soluna overall.

With this addition, Blockware’s total deployed capacity across Soluna sites now exceeds 17 MW. Project Dorothy 1B is a 25 MW facility co-located with and powered by the Briscoe Wind Farm, which Soluna recently acquired in a $53 million transaction to support vertically integrated, renewable-powered computing for Bitcoin mining and AI workloads.

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%.

Soluna Holdings has acquired Spring Lane Capital’s equity interest in Project Dorothy 1A for $16.5 million, giving it 100% ownership of the data center project in Silverton, Texas. The move follows Soluna’s earlier $53 million purchase of the Briscoe Wind Farm, which provides 150 megawatts of owned renewable power.

By fully consolidating Dorothy 1A and Briscoe, Soluna aims to create a vertically integrated AI-focused campus, converting existing infrastructure from primarily Bitcoin mining to AI workloads as Dorothy 3 development advances. The company financed part of the deal with a $12 million unsecured promissory note maturing on May 15, 2027, and continues to pursue full ownership of the broader Dorothy campus while advancing a development pipeline exceeding 4.3 gigawatts across multiple sites.

Soluna Holdings, Inc. received a Nasdaq notice that its common stock has closed below $1.00 for 30 consecutive business days, violating the exchange’s minimum bid price requirement for the Nasdaq Capital Market.

The company has 180 calendar days, until October 7, 2026, to regain compliance by maintaining a closing bid of at least $1.00 for ten consecutive business days. The notice does not immediately affect trading, but failure to regain compliance could ultimately lead to delisting, although Soluna could seek an additional 180-day period or appeal a delisting determination.

Soluna Holdings, Inc. provides a March 2026 business update highlighting record 2025 growth, a development pipeline above 4.3 GW, a total of $142 million raised, and the launch of AI infrastructure initiatives.

The company reports strong Bitcoin hosting operations at its Project Dorothy sites, substantial completion and commissioning of the 48 MW Kati 1A Galaxy facility, and continued construction of the 35 MW Kati 1B site. It is advancing Project Kati 2 and Project Grace for AI and high-performance computing, including site design, power options, and long-lead equipment procurement. The update also notes broader pipeline progress across multiple U.S. power markets and the appointment of KPMG LLP as new independent auditor for the fiscal year ended December 31, 2026.

Soluna Holdings, Inc. entered into a Membership Interest Purchase Agreement under which a subsidiary acquired 100% of Briscoe Wind Farm, LLC, owner of a roughly 149.85 MW wind project in Texas, for an aggregate closing payment of about $53,000,000. The acquisition closed simultaneously with signing on April 1, 2026, and the sellers’ existing credit facility and subordinated notes were fully repaid.

The company also amended its senior secured Credit and Guaranty Agreement, adding a new Tranche C borrower and establishing $12,500,000 of Tranche C loan commitments to finance the Briscoe project. Tranche A and B loans carry SOFR margins of 10.0% per annum and Tranche C carries an 8.0% margin, each with an ABR option at slightly lower margins and a SOFR floor of 3.50%.

In connection with the amendment, Soluna privately issued a pre-funded warrant for up to 700,000 common shares at an exercise price of $0.0001, plus common warrants for up to 1,350,000 shares at $0.68 and 650,000 shares at $0.75. The company agreed under an amended and restated registration rights agreement to register the resale or other disposition of these warrants and the underlying shares, subject to specified filing and effectiveness timelines.

Soluna Holdings, Inc. has closed the acquisition of the 150 MW Briscoe Wind Farm in West Texas for a total purchase price of $53.0 million, funded with cash and debt. The deal is expected to be immediately accretive, with projected Year-One Adjusted EBITDA of $6 million to $11 million and annualized revenue of $20.0 million to $24.4 million.

By acquiring the wind farm that powers Project Dorothy, Soluna achieves full vertical integration, owning the power, land, and compute for its green data center campus. This positions the company to advance Dorothy 3, a planned renewable-powered AI campus on 300 new acres with potential capacity of up to 300 MW+.

The company highlights a broader development pipeline exceeding 4.3 GW, including the recently energized 83 MW Project Kati 1 and the planned 300+ MW Project Kati 2 AI campus in partnership with Metrobloks, reinforcing its focus on renewable-powered high-performance computing and generative AI workloads.

Soluna Holdings, Inc. changed its external auditor. On March 29, 2026, the company dismissed UHY LLP as its independent registered public accounting firm and the Audit Committee approved this decision, effective the same day.

UHY’s audit reports on the financial statements for the fiscal years ended December 31, 2025 and 2024 contained no adverse opinions, disclaimers, or qualifications, and there were no disagreements or reportable events with UHY during that period. The Audit Committee also approved the appointment of KPMG LLP as the new independent registered public accounting firm for the fiscal year ending December 31, 2026.

Soluna Holdings reported full-year 2025 results showing heavy investment-led growth alongside continued losses. Revenue was $29.7 million, down 21.8% from $38.0 million in 2024 as Bitcoin “hashprice” fell 30.8% and coins mined dropped from 274 to 113.2. Net loss was $57.0 million, slightly better than the $58.3 million loss in 2024, while Adjusted EBITDA swung to -$13.2 million from +$0.9 million.

The company raised about $142 million in 2025 and lifted total cash and restricted cash to $88.8 million, a 750% increase, supporting project build-out. Property, plant and equipment grew 58% to $74.8 million as Soluna completed the 48MW Dorothy 2 site, advanced the 83MW Kati 1 facility, and began planning the Kati 2 AI and high‑performance computing campus. Its long-term power pipeline expanded to over 4.3 GW, positioning the business for AI and data hosting growth despite near-term Bitcoin-driven margin pressure.

Soluna Holdings released a February 2026 operational update covering Bitcoin mining performance and data center project milestones. Hosted hashrate averaged 3,883 PH/s and self-mining hashrate 760 PH/s, producing 9.5 BTC for the month.

At Project Dorothy, customer deployments and a 6 MW Blockware expansion brought the 50 MW campus back to full capacity. At Project Kati 1, the first 24 MW phase of K1A Galaxy reached substantial completion and steady-state operations, with the next 24 MW scheduled ahead of prior timing in March.

The company is advancing its AI and high‑performance computing strategy through Project Kati 2 and Project Grace, refining procurement for an initial 100 MW of critical IT capacity and engaging prospects interested in 350 MW, while progressing power and land agreements across its broader development pipeline.

Soluna Holdings filed a current report describing an expansion of its partnership with Blockware at the Dorothy 1 data center site in west Texas. The companies are adding an additional 6 megawatts of capacity, marking the third expansion of this relationship.

Deployment of the new capacity began in January and is expected to be completed by the end of February. Soluna highlights that repeat expansions with Blockware support its renewable-powered, behind-the-meter computing model focused on Bitcoin mining, AI, and other intensive workloads.

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. 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.
