Item 1.01 – Entry into a Material Definitive Agreement.

On November 7, 2025, Greenidge Generation LLC (“Greenidge”), a wholly-owned subsidiary of Greenidge Generation Holdings Inc. (the “Company”), entered into a Stipulation of Settlement (the “Stipulation”) with the New York State Department of Environmental Conservation (the “Department”), which provides a pathway to resolve ongoing administrative and judicial proceedings concerning renewal of Greenidge’s Title V Air Permit for its power generation facility in Dresden, New York (the “Facility”) consistent with New York’s Climate Leadership and Community Protection Act.

Pursuant to the terms of the Stipulation, Greenidge submitted to the Department an application (the “Application”), supplementing the Title V Air Permit renewal application previously submitted by Greenidge to the Department on March 5, 2021 (the “2021 Permit Renewal Application”), to modify and renew its existing Title V Air Permit to incorporate new greenhouse gas (“GHG”) emissions limits and related monitoring and reporting requirements set forth in Schedule 1 of the Stipulation.

Pursuant to the terms of the Stipulation, the Department agreed to process the Application pursuant to the New York State Uniform Procedures Act and 6 NYCRR Part 621, and issue a draft Title V permit modification and renewal (the “Draft Title V Permit”) that includes substantially the same conditions as the 2021 Permit Renewal Application and the GHG limits and reporting obligations agreed upon in the Stipulation. The Draft Title V Permit will be subject to a public notice and comment period in addition to a 45-day review period by the U.S. Environmental Protection Agency.

Upon completion of the administrative process and withdrawal of Greenidge’s pending appeal before the New York State Supreme Court Appellate Division, Fourth Department, the Department shall issue a final Title V Air Permit consistent with the GHG emission limits set forth in Schedule 1 of the Stipulation. The GHG emissions limits established in Schedule 1 of the Stipulation are as follows (measured in tons of CO₂e per year, on a 12-month rolling average): (i) 475,683.48 in Permit Year 1; (ii) 475,683.48 in Permit Year 2; (iii) 428,115.13 in Permit Year 3; (iv) 380,426.78 in Permit Year 4; and (v) 358,071.27 in Permit Year 5.

The Stipulation provides that, during Permit Years 3 and 4, to the extent that the Facility is dispatched to provide power to the grid above the number of megawatts (MW) it provided to the grid at the time of the Department’s June 2022 denial of the 2021 Permit Renewal Application, the emissions associated with the increased MWs shall not count toward the emissions limits in Permit Years 3 and 4; provided, however, that the Facility’s emissions in Permit Years 3 and 4 shall not exceed the actual emissions limit for the immediately preceding Permit Year, as applicable.

The Stipulation further provides that, following Permit Year 5 (provided that the Facility operates under the final Title V Air Permit), the Facility’s GHG emissions may not exceed 358,071.27 tons of CO₂e per year unless expressly authorized by the Department in the form of a subsequent permit modification.

Greenidge’s existing Title V Air Permit remains valid pursuant to Section 401(2) of the New York State Administrative Procedure Act throughout the administrative process set forth in the Stipulation.

The foregoing description of the Stipulation does not purport to be complete and is qualified in its entirety by reference to the full text of the Stipulation, including Schedule 1 thereto, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated in its entirety herein by reference.
