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.

*Note: Long-term contracted average. Does not represent a month-to-month average.
