John Belizaire, CEO of Soluna Holdings, said, “We are delighted to announce the successful completion of Project Dorothy 1B, marking a significant milestone for Project Dorothy. The project is now fully operational, and we are witnessing the tangible impact of its earnings potential.”

Belizaire went further on to say, “Our dedicated team has demonstrated exceptional execution across our four strategic focus areas, as outlined in our shareholder letter: the energizing of Project Dorothy, Cash Flow and Expense Management, Expanding our Flagship, and Growing our Pipeline. The business transition initiated in Q2 is yielding positive results, evident in our latest financials.

Finance and Operational Highlights:

Substantial cash balance - The unrestricted cash balance as of September 30, 2023, was $5.6 million compared to $1.1 million as of December 31, 2022. This is driven by new project-level investments, operational execution, and expense management measures implemented in the first half of the year.

EBITDA Milestone - The Company achieved a positive Adjusted EBITDA for the first time since second quarter 2022.

Revenue Ramp - Revenue in the third quarter increased by 176% to $5.8 million compared to $2.1 million in the second quarter of 2023. The revenue increase is driven by the continued ramp in the Project Dorothy sites, including hosting and proprietary mining.

Project Dorothy 1A and 1B fully operational as of October 31 2023 - Installed hashrate of 1.76 EH/s in Project Dorothy 1A/1B fully and it is fully operational. This brings the Company’s total installed hashrate to 2.6 EH/s. Project Dorothy consumed over 4,000 MWh of curtailed energy through the end of October solidifying the effectiveness of Soluna’s innovative solution to monetizing curtailed energy.

Ancillary services revenue - The Company completed its pre-registration for Ancillary Services with ERCOT, bringing it closer to diversifying its revenue by having Project Dorothy serve as a grid resource.

As of the end of the third quarter of 2023, Soluna deployed over 23,600 bitcoin miners (between hosting and prop mining) across all sites. And, the Company operated at an average hashrate of 2.4 EH/s across all sites as Project Dorothy became fully energized by late summer.

AI initiative - The Company launched a new initiative focused on a new data center purpose-built for AI training workloads. The new design, code-named “Helix”, will be part of Project Dorothy 2; due to start in the first quarter of 2024. The Company also formed a new Advisory Board to accelerate the Company’s AI initiatives and tapped Daniel Golding, a former head of advanced engineering and data center innovation at Google.
