Key Company Metrics:

Previously, operational and project updates provided insights into partial-month progress. Going forward, the company will release monthly updates recapping activities from the previous months only.
Metrics for all sites are as of December 31, 2023.
The data in the site charts throughout the release reflect a consistent calculation of power consumption using month-over-month versus a year-to-date calculation, which is now standard for all business updates from the Company going forward. Edits have also been made to improve clarity.
All power consumption metrics are cumulative, year-to-date, totals.
Curtailed Energy is energy produced by the wind farm and consumed by Soluna's Project Dorothy which the grid either could not absorb or was not economically valuable.
Average Power Cost is a long-term contracted average. It does not represent a month-to-month average.
Average Hashrate decreased at Project Dorothy due to increased curtailments resulting from the cold weather in December and January.
Project Sophie's Average Hashrate decreased as the Company began rolling in its new 8.8 MW customer.
Project Dorothy Average Hashrate was also affected by a wind farm substation outage in late December.
