Item 1.01 Entry into a Material Definitive Agreement.
On June 30, 2021, Stronghold Digital Mining Equipment, LLC (“Equipment”), a wholly owned subsidiary of Stronghold Digital Mining, Inc. (the “Company”), entered into an equipment financing agreement (the “WhiteHawk Financing Agreement”) with WhiteHawk Finance LLC (“WhiteHawk”) whereby WhiteHawk originally agreed to lend to Equipment an aggregate amount not to exceed $40.0 million to finance the purchase of certain Bitcoin miners and related equipment. The WhiteHawk Financing Agreement originally contained terms requiring that the 15,000 miners being purchased pursuant to a purchase agreement (the “MinerVa Purchase Agreement”) with MinerVa Semiconductor Corp. (“MinerVa”) be delivered on or before December 31, 2021. Failure to deliver the miners by the deadline contained in the WhiteHawk Financing Agreement would result in an Event of Default which could only be cured by a waiver from WhiteHawk. Such Event of Default would give WhiteHawk the right to accelerate all amounts then outstanding under the WhiteHawk Financing Agreement. MinerVa did not deliver all of the miners under the MinerVa Purchase Agreement by the December 31, 2021 deadline. The Company has received over 1,000 of the miners to date, and MinerVa has advised the Company to expect delivery of the remaining miners under the agreement to arrive by the end of March 2022. On December 31, 2021, Equipment and WhiteHawk amended the WhiteHawk Financing Agreement (the “WhiteHawk Amendment”) to extend the Final Minerva Delivery Date from December 31, 2021 to April 30, 2022. Failure to deliver the miners by April 30, 2022 will result in an Event of Default under the WhiteHawk Financing Agreement and WhiteHawk having the right to accelerate all amounts then outstanding under the WhiteHawk Financing Agreement. Pursuant to the WhiteHawk Amendment, Equipment paid an Amendment Fee in the amount of $250,000 to WhiteHawk. All capitalized words used but not defined herein have the meanings assigned in the WhiteHawk Amendment.

The foregoing description is qualified in its entirety by reference to the full text of the WhiteHawk Financing Agreement, which is filed as Exhibit 10.17 to the Company’s Registration Statement filed in connection with its initial public offering (File No. 333-258188) and incorporated into this Item 1.01 by reference, and the WhiteHawk Amendment, which is attached as Exhibit 10.1 to this Current Report on Form 8-K (this “Form 8-K”) and incorporated into this Item 1.01 by reference.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The information included under Item 1.01 of this Form 8-K is incorporated by reference into this Item 2.03 of this Form 8-K.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On November 17, 2021, the Board of Directors (the “Board”) of the Company appointed Matthew J. Smith to the Board, and no determinations regarding any committee assignments were made at that time. On January 3, 2022, the Board appointed Mr. Smith to the Compensation Committee and the Audit Committee of the Board, effective immediately. The Board determined that Mr. Smith satisfied the additional independence requirements of the Nasdaq Stock Market and the Securities and Exchange Commission applicable to members of the Compensation Committee and Audit Committee.






Additionally, the Board also modified the composition of other Board committees as follows, all effective as of January 3, 2022:

Audit Committee: Matthew J. Smith (chair), Thomas J. Pacchia and Sarah P. James

Compensation Committee: Matthew J. Smith (chair), Thomas J. Pacchia and Thomas R. Trowbridge, IV

Nominating and Corporate Governance Committee: Sarah P. James (chair) and Thomas R. Trowbridge, IV

Item 7.01 Regulation FD Disclosure

On January 6, 2022, the Company issued a press release announcing the WhiteHawk Amendment and other events and milestones related to the Company’s mining activity. A copy of the press release is furnished herewith as Exhibit 99.1 and incorporated herein by reference.

The information in this Item 7.01 of this Form 8-K, including Exhibit 99.1, is being “furnished” pursuant to General Instruction B.2 of Form 8-K and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth in such filing.

Item 8.01 Other Events

General Business Update

On January 6, 2022, the Company announced that it has exceeded 1.3 exahash per second (“EH/s”) of total hash rate capacity with over 14,000 miners received to date, over 8,700 of which were received in the last five weeks. The Company previously reported total hash rate capacity of approximately 185 petahash per second (“PH/s”) from approximately 3,000 miners as of September 30, 2021 and approximately 470 PH/s from nearly 6,000 miners as of November 29, 2021. Additionally, the Company has commenced mining Bitcoin at the Panther Creek power plant, the 80-megawatt reclamation and power generation facility that the Company acquired on November 2, 2021 (the “Panther Creek Plant”), and the Company continues to scale the operation at the Panther Creek Plant. The Company expects the Scrubgrass power plant located in Nesquehoning, Pennsylvania and the Panther Creek Plant to support Bitcoin miners with total hash rate capacity exceeding 4 EH/s by the end of the second quarter of 2022.
