Stronghold’s Differentiated Business Model 3 The value of vertical integration 1 Own and Operate Power Generation Assets ➢ Maximizes efficiency and reduces costs ➢ Provides downside protection and ability to sell to grid (improving grid stability) ➢ Currently similar or better economics selling power to grid than mining BTC 2 Own, Develop, and Operate Datacenters ➢ Helps reduce costs (capex & opex) ➢ Minimizes supply-chain risk and counterparty risk ➢ Improves operational control 3 Own and Operate Bitcoin Miners ➢ Stronghold is a reliable partner to manufacturers and other suppliers of miners

Recap of Recent Deleveraging Transactions: What We Did ➢ Strategically approached NYDIG to restructure equipment financing in July given decline in collateral value ➢ Eliminated ~$67.4mm of outstanding principal in exchange for returning NYDIG-financed miners (~2.5 EH/s of YE 2022E hash rate capacity) ➢ Financing was non-recourse to Stronghold, which enabled the proactive restructuring 7Note: the above descriptions of the Transactions are qualified in their entirety by the Company’s Current Report on Form 8-k filed August 16, 2022, including the exhibits thereto Announced restructuring of all material financing agreements on August 16th NYDIG Restructuring ➢ Received binding commitment letter to restructure financing, subject to closing of NYDIG restructuring ➢ Replacing existing equipment financing with a 36-month secured note at SOFR+10% ▪ More than 2x the weighted-average term of existing financing ➢ $20mm additional commitment to purchase miners WhiteHawk Restructuring ➢ Amended documents to allow for complete equitization of principal, at our option ➢ Principal amount reduced by $11.25mm in exchange for reducing strike price on ~6.3mm warrants from $2.50/share to $0.01/share ➢ Remaining $22.5mm of principal amount outstanding can be repaid with common stock or cash over next few quarters Convertible Notes Restructuring

Recap of Recent Deleveraging Transactions: Why We Did It Shift value from debt to equity ➢ Eliminating ~$67mm of debt in exchange for assets with estimated market value of ~$40-50mm ▪ Effectively transferring ~$17-27mm of value to shareholders Enhance capital structure ➢ ~$79mm reduction in principal amount outstanding (>$100mm reduction with convertible notes equitized) ▪ By end of Q1 2023, expect debt outstanding to be ~66% lower than pre-restructuring ➢ Our strategy has not changed; we plan to achieve the same hash rate, just with significantly less debt Dramatically improve liquidity profile ➢ Cash principal and interest payments reduced by ~$113mm through YE 2023 8 Transactions will improve capitalization, liquidity position, and long-term shareholder value

Path to Generate Improved Shareholder Value 9 1. Revenue range for miners based on a Bitcoin price range of $17,500 to $22,500 and a 225 EH/s network hash rate 2. Average of around-the-clock forward prices for the Penelec and PPL PJM zones, per Priority Power as of 9/9/22 Take advantage of historically high grid prices and opportunistically fill mining capacity ➢ Vertical integration provides opportunity to sell power into historically tight power market ➢ Combination of high power prices and low BTC prices means we would likely be directing power to the grid through the winter anyway ➢ Strategy unchanged in medium- and long-term ➢ Bitcoin mining remains our core business ▪ ~227 BTC mined in August ➢ Will opportunistically purchase miners in depressed equipment market ▪ Facilitated by improved liquidity position ▪ Will be very disciplined – no rush to replace miners given attractive grid prices ➢ Own at least 4 EH/s of finished, energized datacenter slots ▪ Plan to start filling capacity immediately and complete by 1H 2023 ▪ MinerVa recently agreed to supply additional 500 Bitmain S19j Pros and 680 Bitmain T19s in place of MinerVa miners (1-for-1 hash rate swap) under 2021 miner purchase agreement Sell to Grid in Near-term Fill Mining Capacity in Coming Quarters $40 $80 $120 $160 Oct-22 Nov-22 Dec-22 Jan-23 Feb-23 Forward Grid Prices Average Forward Grid Price Grid Prices and Mining Revenue ($/MWh) Bitmain S19j Pro 1 MicroBT M30S 1 2
