Soluna Holdings, a renewable-powered data center operator spanning Bitcoin mining and developing AI infrastructure, reported rapid revenue growth in the second quarter alongside weaker consolidated profitability.
The company reported $15.1 million of revenue for the three months ended June 30, up 145% from $6.2 million a year earlier. A new presentation of pass-through electricity costs added $4.4 million to both revenue and cost of revenue, with no effect on gross profit, operating loss or net loss. Excluding that change, revenue still grew 73%.
Project Kati 1 completed 48 MW of construction and recorded its first positive site gross profit of $82,000. Project Dorothy 1A generated $2.9 million of revenue and $795,000 of gross profit.
Consolidated gross profit nevertheless fell 60% from the first quarter to $766,000. Soluna attributed the pressure mainly to $1.5 million of maintenance costs at the recently acquired Briscoe Wind Farm, ramp costs at Kati 1, and depreciation that began before the sites delivered their full revenue contribution.
The consolidated GAAP net loss widened to $22.6 million from $17.9 million in the first quarter and $7.8 million a year earlier. The Bitcoin miner's quarterly filing also recorded a $4.2 million loss on debt extinguishment.
Soluna financed a mix of operating needs, acquisitions, and development through substantial equity issuance. Outstanding common shares rose from 102.5 million on Dec. 31, 2025, to 225.8 million on June 30, an increase of 120%.
During the first half, the company sold 74.2 million shares through its at-the-market program, generating net proceeds of $113.5 million, and issued an additional 10.2 million shares under a standby equity purchase agreement, generating net proceeds of $18.9 million.
First-half cash uses included $11.6 million of operating cash burn, $65.1 million of investing outflow, including $51.4 million net for Briscoe, and $25.3 million for interests in Dorothy 1A and 1B.
Soluna sold 18.8 million additional ATM shares for about $23.6 million, lifting the outstanding count to 244.6 million as of Aug. 10, 139% above the year-end level.
The capacity behind Soluna’s AI pivot remains far smaller than its headline pipeline. As of Aug. 1, the company said the pipeline totaled about 6.3 GW, but only about 192 MW, or roughly 3%, was operating across three fully energized sites.
Another 14 MW was under construction at Kati 1, while 1.6 GW was in planning and development and 4.5 GW was in assessment with power partners.
Kati 2 illustrates the gap between development plans and active infrastructure. The joint venture with Metrobloks calls for 100 MW of critical IT capacity in its first phase and another 250 MW in a second phase, but neither phase was included in operating capacity.
For now, Soluna’s measurable base is 192 MW operating, with more than 6 GW still in construction, planning, development, or assessment, and a share count that reached 244.6 million.
