Company Description
Stronghold Digital Mining, Inc. (NASDAQ: SDIG) is described in its public communications as a vertically integrated Bitcoin mining company with an emphasis on environmentally beneficial operations. According to multiple company press releases, Stronghold houses its Bitcoin miners at its wholly owned and operated Scrubgrass and Panther Creek plants in Pennsylvania. These plants are characterized as low-cost, environmentally beneficial coal refuse power generation facilities that support the company’s digital asset mining activities.
Stronghold appears in news releases as a crypto asset mining company focused on Bitcoin. The company’s operations combine power generation and Bitcoin mining at the same locations, which it refers to as a vertically integrated model. In these communications, Stronghold notes that its Scrubgrass and Panther Creek plants are coal refuse power generation facilities in Pennsylvania and that its business is highly dependent on the economics of Bitcoin mining and the broader crypto asset industry.
Business focus and operations
In its own descriptions, Stronghold presents itself as a Bitcoin-focused miner. It reports that it generates revenue from cryptocurrency operations and from the sale of energy produced at its plants. The company’s public updates frequently refer to Bitcoin mined during specific periods and to additional revenue from energy sales, expressed as Bitcoin-equivalent production based on the average price of Bitcoin in those periods.
Stronghold’s press releases also describe a hybrid business model that depends on both Bitcoin mining and participation in regional power markets. The company highlights that its Scrubgrass and Panther Creek plants are coal refuse power generation facilities, and it references the use of these plants to support Bitcoin mining operations and, in some cases, to sell energy into the grid.
Environmental and regulatory context as presented by the company
In a transaction announcement involving Bitfarms Ltd., Stronghold is described as a vertically integrated crypto asset mining company focused on mining Bitcoin and on environmental remediation and reclamation services. That announcement states that Stronghold owns the Scrubgrass and Panther Creek power plants in Pennsylvania and notes that these plants are recognized by Pennsylvania as a Tier 2 Alternative Energy Source for their environmental benefits. The same disclosure states that, in coordination with the Pennsylvania Department of Environmental Protection, these facilities remove mining waste and convert it into power through a specialized process.
Stronghold’s own press releases also reference a coal refuse reclamation and energy tax credit program in Pennsylvania and discuss legislative changes that increase the value and caps of this tax credit. The company states that this program is effective through 2036 and that it expects the increased credit to contribute incremental net income, linking its coal refuse power generation activities to state-level environmental and energy policy.
Sites, power and data center potential
Stronghold’s disclosures describe its Scrubgrass and Panther Creek sites as large land positions in Pennsylvania with power infrastructure. In the Bitfarms transaction announcement, Stronghold is said to own over 750 acres of land with options on over 1,100 additional acres, along with the Scrubgrass and Panther Creek merchant power plants. In its own second quarter 2024 results release, Stronghold notes that the Scrubgrass site is 636 acres and that it has secured an option to purchase additional land adjacent to the Panther Creek site. The company states that it has submitted preliminary load studies to local utilities to import additional megawatts of power at both sites and that it views these locations as having potential for data center expansion.
Stronghold has also engaged an external advisor, Appleby Strategy Group LLC, to evaluate additional potential uses for the Scrubgrass and Panther Creek sites. According to Stronghold, initial assessments from this advisor emphasize access to land, electricity, fiber and water as traits that may make the sites attractive for large-scale data center development. The company also references guidance from PJM Interconnection LLC regarding co-located load and notes that it believes its data center loads qualify as PJM “In Network” load, which it associates with potential participation in demand response programs.
Merger agreement with Bitfarms
Stronghold has entered into an Agreement and Plan of Merger with Bitfarms Ltd. Under this agreement, Bitfarms will acquire Stronghold in a stock-for-stock merger transaction, subject to regulatory approvals and other customary closing conditions. A later press release states that Stronghold stockholders have overwhelmingly approved the pending merger between Stronghold and Bitfarms. In that release, Stronghold reports that approximately 99.6% of votes cast at a special meeting approved the merger proposal, representing a majority of the issued and outstanding shares entitled to vote. The company indicates that it expects the closing of the merger to occur after remaining conditions are satisfied or waived.
The Bitfarms transaction announcement describes Stronghold’s contribution to the combined company in terms of hashrate, power capacity and access to the PJM grid. It notes that Stronghold has a hashrate of 4.0 exahash per second and 165 megawatts of nameplate generated power capacity as of a stated date, with additional PJM import capacity and potential expansion. These figures are presented in the context of Bitfarms’ plans for its overall energy portfolio and Bitcoin mining capacity.
Strategic review and site expansion initiatives
Before entering into the merger agreement, Stronghold reported that it was conducting a formal strategic review process with the assistance of outside financial and legal advisors. The company stated that it had received numerous bids for all or parts of the company and that it was considering alternatives such as the sale of all or parts of the company, other strategic transactions involving some or all of its assets, and strategic financing. Stronghold emphasized that there was no fixed timetable for this process and that there could be no assurance that any transaction would be completed.
As part of this strategic review, Stronghold has described efforts to expand and enhance its existing sites. It has submitted preliminary load studies to import additional power at Panther Creek and Scrubgrass and has obtained an option on additional land near Panther Creek. The company indicates that it is evaluating these opportunities in light of potential data center development and possible participation in PJM demand response programs, while also considering its existing capacity commitments in PJM auctions.
Bitcoin mining and energy revenue disclosures
Stronghold’s periodic updates provide detail on its Bitcoin mining activity and related energy revenue. For example, the company has disclosed the number of Bitcoin mined in specific months and quarters, the amount of energy revenue generated (sometimes expressed as Bitcoin-equivalent based on average Bitcoin prices), and the resulting total Bitcoin-equivalent production. It has also discussed the impact of the Bitcoin halving event on its production and referenced metrics such as hash price as a preferred measure of Bitcoin mining economics.
These disclosures underscore Stronghold’s focus on Bitcoin mining as a core activity, while also highlighting the role of its coal refuse power generation facilities in providing energy for mining and, in some cases, for sale into power markets. The company’s risk factor discussions in its press releases emphasize dependence on Bitcoin prices, the crypto asset industry, regulatory developments and its ability to operate its coal refuse power generation facilities and to access tax credits related to coal refuse cleanup.
Carbon capture and environmental initiatives as described by the company
Stronghold has reported on a carbon capture initiative associated with its Scrubgrass plant. It has disclosed test results indicating carbonation of ash by a certain percentage of starting weight and has stated that it is pursuing accreditation with the Puro registry. The company frames this initiative as a potential source of revenue and as part of its broader environmental activities linked to coal refuse reclamation and power generation.
In the Bitfarms transaction announcement, Stronghold’s facilities are described as having reclaimed thousands of acres of toxic waste and as reducing environmental impacts from historical mining activities. The same announcement refers to Stronghold’s carbon capture projects as having the potential to capture significant amounts of carbon dioxide annually, and it characterizes these projects as among large potential carbon capture efforts, based on the information provided there.
Corporate developments and leadership changes
Stronghold has also disclosed corporate developments such as a chief financial officer transition. In a press release, the company announced that its chief financial officer would resign after the filing of a quarterly report and that he would step down from the board of directors at that time. Stronghold stated that the resignation was not due to any disagreement on matters relating to operations, policies or practices and that it intended to retain the departing executive as a consultant for a transition period.
Company status and trading symbol
Stronghold Digital Mining, Inc. is identified in its press releases as a company whose Class A common stock trades on Nasdaq under the symbol SDIG. The merger-related disclosures indicate that, following completion of the merger with Bitfarms, Stronghold stockholders are expected to receive Bitfarms shares in exchange for their Stronghold shares.
