**Item 1.01 – Entry into a Material Definitive Agreement.**<br>

On November 26, 2025, 300 Jones Road LLC, a wholly owned subsidiary of Greenidge Generation Holdings Inc. (collectively with each of its affiliates, the "Company"), entered into a Purchase and Sale Agreement and Joint Escrow Instructions (as amended, the "Purchase Agreement") with 300 Jones Road Associates LLC (the "Purchaser"), an affiliate of Lightstone Parent LLC (the "Guarantor") and LightHouse Data Centers LLC, pursuant to which the Company has agreed to sell to the Purchaser two parcels of land totaling approximately 152 acres located in Spartanburg, South Carolina (the "Property") and to assign to the Purchaser the Company's rights to 60 megawatts ("MW") of electrical service (the "Initial Load"), which is expected to be made available to the Property in September 2026 (the "Transaction"), for the following consideration: (i) $18.0 million in cash (subject to upward adjustment for certain expenses incurred by the Company in connection with its design, development and construction of a 60 MW substation to be located on the Property) (as so adjusted, the "Initial Purchase Price") payable by the Purchaser to the Company on the Closing Date (as defined below); and (ii) the Company's right to receive future cash payments from the Purchaser, not to exceed an additional $18.0 million in the aggregate, conditioned upon the availability of additional electrical capacity to the Property in excess of the Initial Load prior to December 31, 2030 (such payments, the "Success Payments").

Pursuant to the terms of the Purchase Agreement, any Success Payments will be made by the Purchaser to the Company no later than three months after any such additional energization in excess of the Initial Load at a rate of $180,000 per MW. As security for the Purchaser's obligations to make any Success Payments owed to the Company, the Guarantor delivered to the Company an irrevocable guarantee pursuant to a Joinder executed concurrently with the Purchase Agreement.

The Transaction is expected to close on the later of (i) December 11, 2025 and (ii) the date that is two business days following the delivery of certain executed documentation from the local utility provider required to effectuate the assignment of the Initial Load to the Purchaser (such later date, the "Closing Date"). To secure the Purchaser's performance obligations under the Purchase Agreement, the Purchaser has deposited into escrow a non-refundable deposit of $1.5 million, which will be applied to the Initial Purchase Price at closing.

Each of the Company and the Purchaser has made customary representations and warranties in the Purchase Agreement, and the Company has agreed to customary covenants regarding the operation of the Property. The consummation of the Transaction is subject to customary closing conditions, including, without limitation: (i) delivery of customary closing deliverables (including special warranty deed, general assignments, authority certificates, tax affidavits and closing statements); (ii) payment of the Initial Purchase Price (inclusive of the $1.5 million escrow deposit); (iii) the title company's irrevocable commitment to issue an owner's title policy for the Initial Purchase Price, subject to certain permitted exceptions; and (iv) delivery of the executed documentation from the local utility provider necessary to effectuate the assignment of the Initial Load to the Purchaser.

The foregoing description of the Purchase Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement, 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.

![](purchasandsaleagreementa002.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;instructions executed by the parties pursuant to the provisions of Section 1.5 hereof. All interest accruing on such sums shall become a part of the Deposit and shall be distributed as amounts of the Deposit in accordance with the terms of this Agreement. The Deposit shall be non-refundable to Purchaser except as expressly set forth in this Agreement. 1.5 Delivery to Title Company. Upon mutual execution of this Agreement, the parties hereto shall deposit an executed copy of this Agreement with Title Company, and this Agreement shall (along with such supplementary instructions not inconsistent herewith as either party hereto may deliver to Title Company) serve as escrow instructions to Title Company for the consummation of the purchase and sale contemplated hereby. Seller and Purchaser agree to execute such additional escrow instructions as Title Company may reasonably require and which are not inconsistent with the provisions hereof and which do not impose additional obligations other than de minimis obligations; provided, however, that in the event of any conflict between the provisions of this Agreement and any supplementary escrow instructions, the terms of this Agreement shall control. 1.6 Independent Consideration. The parties mutually acknowledge and agree that in the event of any termination of this Agreement for any reason, Seller shall be entitled to retain a portion of the Deposit, in the amount of One Hundred Dollars ($100) (the "Independent Consideration"), which amount has been bargained for as consideration for Seller's execution of this Agreement. The Independent Consideration is non-refundable in all events. Any provision herein that entitles Purchaser to a return of the Deposit upon termination or cancellation of this Agreement shall be construed to provide for a return of the entire portion of the Deposit less the Independent Consideration. 1.7 Pre-Closing Substation Work. Notwithstanding anything to the contrary contained herein, the Purchase Price shall be subject to an upward adjustment to reflect (A) an increase in an amount equal to $85,729.21 in respect of pre-Effective Date work and (B) the documented expenses actually incurred and paid for by Seller and its affiliates from and after Effective Date and prior to the Closing (the "Closing Period") for improvements, repairs, upgrades, and other work performed on the 60 MW substation (the "Substation") to be located on the Property pursuant to one or more contracts to be entered into by Seller following the Effective Date that have been approved by Purchaser, such approval not to be unreasonably withheld, conditioned or delayed (collectively, the "Pre-Closing Substation Work Contracts" and each, a "Pre-Closing Substation Work Contract", and such work to be performed thereunder, the "Pre-Closing Substation Work"), provided such Pre-Closing Substation Work is approved in writing by Purchaser, with such consent not to be unreasonably withheld, conditioned, or delayed and, provided, further, in no event shall the upward adjustment pursuant to the foregoing clause (B) exceed ONE MILLION FIVE HUNDRED THOUSAND DOLLARS ($1,500,000), unless mutually agreed to in writing by Seller and Purchaser in their respective sole and absolute discretion. The adjustment amount pursuant to the foregoing clause (B) shall be equal to the actual costs incurred and paid for by Seller during the Closing Period, as evidenced by receipts, invoices, contractor bills, permits, or other reasonable documentation provided to Purchaser. Purchaser may only withhold consent if the proposed Pre-Closing Substation Work is demonstrably unnecessary or not beneficial to the operation, maintenance, or value of the Substation, as supported by written evidence from a mutually agreed upon and qualified third-party engineer or industry expert. The adjusted Purchase Price shall be reflected in the final settlement statement at Closing. The Parties

------

![](purchasandsaleagreementa003.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;acknowledge and agree that, prior to the Effective Date, Seller has provided Purchaser with a detailed description of the proposed Pre-Closing Substation Work, including estimated costs, that will occur after the Effective Date, which description is attached hereto as Exhibit F and which has been approved by Purchaser. Seller acknowledges and agrees that Seller shall not be entitled to reimbursement for any Pre-Closing Substation Work in the event Closing does not occur. ARTICLE II PURCHASER'S DUE DILIGENCE 2.1 Physical Inspection of the Property. (a) Right of Entry. During the period commencing on the Effective Date and until Closing or the termination of this Agreement, Purchaser, through its employees, agents and consultants (collectively, "Agents"), shall be entitled to enter the Property at reasonable times and upon reasonable notice to Seller, to conduct, at Purchaser's sole cost and expense, an inspection of the Property including, without limitation, an inspection of the condition of title to the Property pursuant to Section 2.3 below, and a review and investigation of the effect of any zoning, maps, permits, reports, engineering data, landscape plans, improvement plans, business and development prospects for the Property, the feasibility of developing the Property in accordance with Purchaser's intended use of the Property, regulations, ordinances and laws affecting the Property, and such other matters as Purchaser deems relevant (collectively, the "Investigations"). If the Purchaser desires to do any invasive testing at the Property, Purchaser shall submit a work plan outlining the scope of the work to be performed and obtain Seller's prior written consent to conduct such invasive testing, which consent may be withheld by Seller in its sole discretion. Purchaser shall permit Seller or its representative to be present to observe any testing or other inspection or due diligence review performed on or at the Property. If any inspection or test performed by Purchaser or its authorized agents and contractors disturbs the Property, Purchaser will restore the Property to the same condition as existed immediately prior to any such inspection or test. Notwithstanding anything to the contrary contained herein, prior to the Closing, Purchaser shall not contact any governmental authority or Duke Energy without first obtaining the prior written consent of Seller, which consent will not be unreasonably withheld, and Seller, at Seller's election, shall be entitled to have a representative participate in any telephone or other contact made by Purchaser to a governmental authority or Duke Energy, as the case may be, and present at any meeting by Purchaser with a governmental authority or Duke Energy, as the case may be, it being agreed that, notwithstanding anything herein, neither Purchaser nor any affiliate thereof shall be liable to Seller or any affiliate thereof for any communications made to Duke Energy by or on behalf of Purchaser so long as Purchaser is not in breach of this sentence. (b) Notwithstanding any such Investigation, or anything to the contrary herein contained, Purchaser's obligations hereunder shall not be limited or otherwise affected as a result of any fact, circumstance or other matter of any kind discovered following the date hereof in connection with any such Investigations, access or otherwise. Without limiting the generality of the foregoing: (i) Purchaser agrees that it shall not have any so-called "due diligence period" and that it shall have no right to terminate this Agreement or obtain a reduction of the Purchase Price as a result of any such fact, circumstance or other matter so discovered (including, without limitation, relating to the physical condition of the Property, the operations of the Property or

------

![](purchasandsaleagreementa004.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;otherwise) unless the same otherwise constitutes a default or breach hereunder and (ii) Purchaser shall have no right to terminate this Agreement or obtain a return of the Deposit except as otherwise expressly provided in this Agreement. Nothing contained in the foregoing provisions of this Section 2.1(b) shall limit Purchaser's rights to terminate this Agreement as otherwise expressly set forth herein. (c) Insurance. All Investigations shall be conducted at Purchaser's sole cost and expense and in accordance with all requirements of applicable law. Purchaser agrees that, in making any physical or environmental inspections of the Property, Purchaser and all of Purchaser's Agents entering onto the Property shall carry not less than $2,000,000 combined, single limit, general liability insurance policy of insurance insuring all activity and conduct of Purchaser and its Agents while exercising such right of access and naming Seller as an additional insured. Purchaser will provide Seller with an ACORD (or its equivalent) certificate evidencing such coverage prior to entry on the Property. (d) Purchaser agrees to keep the Property free and clear of any liens filed against the Property and to protect, indemnify, defend and hold Seller and its partners, agents, officers, contractors and employees harmless from and against any and all actual out of pocket: claim for liabilities, losses, costs, expenses (including reasonable attorneys' fees), damages, liens or injuries arising out of or resulting from the inspection of, or entry on, the Property by Purchaser or its agents, but excluding special, consequential, and punitive damages; provided that Purchaser shall not be liable for the discovery of any matter at the Property nor shall Purchaser be liable to the extent of any gross negligence or willful misconduct of Seller or its affiliates. Such obligation to indemnify and hold harmless Seller shall survive any termination of this Agreement for one (1) year. 2.2 Seller's Property Documents. Prior to the Effective Date, Seller has delivered to Purchaser copies of the following documents and materials to the extent within Seller's possession or control (collectively, "Seller's Control") that relate to the Property: (i) the latest real and personal property tax bills and value renditions from all taxing authorities; (ii) any environmental reports; (iii) any written notices, reports, citations, orders, decisions, correspondence, or memoranda from any governmental authority (including, but not limited to, copies of any zoning letters) and applications to any governmental authority; (iv) copies of any service agreements and contracts relating to the upkeep, repair, maintenance or operation of the Property; (v) all permits issued by any governmental authority relating to the operation of the Property and any agreements with any governmental agency or authority; and (vi) Seller's current title insurance policy and existing surveys of the Property (collectively, the "Property Documents"). All of the Property Documents are provided simply as an accommodation to Purchaser, and Seller makes no representations or warranties as to their accuracy; provided, however, the foregoing shall not limit any of Seller's representation and warranties set forth in Section 4.1 below. Purchaser understands that some of the foregoing documents were provided by others to Seller and were not prepared by or verified by Seller for accuracy. Seller shall continue to deliver to Purchaser other similar documents and materials requested by Purchaser in writing that are in Seller's Control; provided that Seller is not obligated to provide any documents or other materials that are Seller's internal memoranda, privileged, confidential or proprietary.

![](purchasandsaleagreementa005.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.3 Approval of Title. (a) Prior to the Effective Date, (i) Seller delivered a copy of the Existing Survey and the Subdivision Plat, and a draft of the Survey Update (as defined below) to Purchaser and (ii) Purchaser ordered a current title commitment for the Property (the "Title Commitment"). As used herein, "Existing Survey" means that certain ALTA/NSPS Land Title Survey dated October 13, 2020, prepared by P.P. Pirkle, Jr., PLS, as Pirkle & Associates Surveying, Inc. network project no. 202002534-002 BLK, and "Subdivision Plat" means that certain Boundary & Re- Combination Survey for 300 Jones Road, LLC prepared by Branyon Land Surveying, Inc. dated September 26, 2023, updated November 2, 2023 and recorded in the Register of Deeds Officer for Spartanburg County on November 8, 2023 in Plat Book 184 at Page 427-427. (b) Prior to the Effective Date, the Title Company has delivered the Title Commitment to Purchaser, a copy of which has been provided to Seller. Purchaser shall have until 5:00 p.m. (Eastern time) on December 3, 2025 (the "Title Approval Date") to (1) review and approve title to the Property (including, but not limited to, the Title Commitment, the exceptions disclosed therein, the Existing Survey, the Subdivision Plat and the Survey Update (defined below)) and (2) obtain from Escrow Holder a proforma title policy for a 2006 ALTA Owner's Policy of Title Insurance (the "Proforma"), in the amount of the Purchase Price, showing the Property vested in Purchaser and subject only to (i) non-delinquent real property taxes and assessments, (ii) local, state and federal laws, ordinances or governmental regulations, including but not limited to, building and zoning laws, ordinances and regulations, now or hereafter in effect relating to the Property (but excluding any violations thereof existing on the Closing Date), and (iii) matters deemed approved by Purchaser pursuant to the last sentence of this Section 2.3(b) (collectively, the "Permitted Exceptions"), together with "extended coverage" and such endorsements thereto as Purchaser shall reasonably require (collectively, the "Title Policy"). Prior to the Effective Date, Seller, at Seller's sole cost and expense, has ordered an update to the Existing Survey (the "Survey Update"), a draft of which has been provided to Purchaser prior to the Effective Date. Seller agrees that in the event Purchaser does not receive the completed Survey Update by December 1, 2025 or in the event Purchaser disapproves title to the Property (such disapproval to be based on reasonable objections specified in writing to Seller with respect to matters that materially impair the Property's development, value or use for datacenter operations and that were not depicted on the Existing Survey) or does not timely receive the Proforma (in a form reasonably acceptable to Purchaser), in either case Purchaser shall have the right to terminate this Agreement by giving written notice thereof to Seller (the "Title Termination Notice") prior to the Title Approval Date. If Purchaser gives the Title Termination Notice on or before the Title Approval Date, this Agreement shall terminate and the entire Deposit plus all accrued interest thereon shall be immediately returned to Purchaser. If Purchaser does not give the Title Termination Notice on or before the Title Approval Date, Purchaser shall be deemed to have waived its right to terminate this Agreement pursuant to this Section 2.3(b), and all title exceptions disclosed on the proforma Title Policy approved by Purchaser on or before the Title Approval Date (the "Approved Proforma") shall be deemed approved by Purchaser. Purchaser shall deliver a copy of the Approved Proforma to Seller promptly after Purchaser's receipt thereof. (c) Notwithstanding anything in this Agreement to the contrary, Seller shall, at its sole cost, on or prior to the Closing, cause to be eliminated from title to the Property, (i) any and all monetary liens and encumbrances (other than liens for non-delinquent real estate taxes and

------

![](purchasandsaleagreementa006.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;assessments, and supplemental taxes and assessments), (ii) mechanic's and materialmen's liens, notices of mechanic's and materialmen's liens, and (iii) any and all judgment liens against the Seller, in each case that are in a liquidated amount and can be satisfied solely by the payment of money (collectively, the "Mandatory Cure Items"), such that the Title Policy will be issued to Purchaser with no exception for Mandatory Cure Items. Seller shall promptly deliver and provide any existing documentation and information required by the Title Company in connection with the Title Company's issuance of mechanic's lien coverage (whether by endorsement or otherwise) under the Title Policy. 2.4 AS-IS. Purchaser agrees that it is buying the property "AS IS" with no representations or warranties whatsoever made by Seller as to the condition of the Property, its intended use or any other matter relating to the Property, except as specifically stated in Section 4.1 of this Agreement. AT CLOSING, PURCHASER SHALL BE DEEMED TO HAVE RELEASED SELLER AND ANY AND ALL SELLER RELATED PARTIES (WITHOUT ANY FURTHER ACTION OF SELLER OR ANY SELLER RELATED PARTIES) FROM ANY AND ALL CLAIMS, LOSSES, DAMAGES, LIABILITIES, COSTS AND EXPENSES WHICH PURCHASER OR ANY PARTY RELATED TO OR AFFILIATED WITH PURCHASER HAS OR MAY HAVE ARISING FROM OR RELATED TO ANY MATTER OR THING RELATED TO THE PROPERTY OR THE PHYSICAL CONDITION OF THE PROPERTY, ANY CONSTRUCTION DEFECTS AND ANY ERRORS OR OMISSIONS IN THE DESIGN OR CONSTRUCTION OF THE PROPERTY AND PURCHASER WILL NOT LOOK TO ANY OF THE SELLER RELATED PARTIES IN CONNECTION WITH THE FOREGOING FOR ANY REDRESS OR RELIEF. THIS RELEASE AT CLOSING INCLUDES CLAIMS OF WHICH PURCHASER IS PRESENTLY UNAWARE OR WHICH PURCHASER DOES NOT PRESENTLY SUSPECT TO EXIST WHICH, IF KNOWN BY PURCHASER, WOULD MATERIALLY AFFECT PURCHASER'S RELEASE TO SELLER. THIS RELEASE WILL BE GIVEN FULL FORCE AND EFFECT ACCORDING TO EACH OF ITS EXPRESS TERMS AND PROVISIONS, INCLUDING THOSE RELATING TO UNKNOWN AND UNSUSPECTED CLAIMS, DAMAGES AND CAUSES OF ACTION. PURCHASER ACKNOWLEDGES THAT THE PURCHASE PRICE (AS HEREINAFTER DEFINED) REFLECTS THE "AS-IS" NATURE OF THIS SALE AND ANY FAULTS, LIABILITIES, DEFECTS OR OTHER ADVERSE MATTERS THAT MAY BE ASSOCIATED WITH THE PROPERTY. PURCHASER HAS FULLY REVIEWED THE DISCLAIMERS AND WAIVERS SET FORTH IN THIS AGREEMENT WITH ITS COUNSEL AND UNDERSTANDS THE SIGNIFICANCE AND EFFECT THEREOF. AS USED HEREIN, "SELLER RELATED PARTY" MEANS ANY OF EACH SELLER'S FORMER, CURRENT AND FUTURE AFFILIATES, AND EACH OF THEIR RESPECTIVE FORMER, CURRENT AND FUTURE DIRECT OR INDIRECT DIRECTORS, OFFICERS, PRINCIPALS, GENERAL OR LIMITED PARTNERS, EMPLOYEES, STOCKHOLDERS, OTHER EQUITY HOLDERS, MEMBERS, MANAGERS, AGENTS, SUCCESSORS, ASSIGNEES, AFFILIATES, CONTROLLING PERSONS OR REPRESENTATIVES. NOTWITHSTANDING THE FOREGOING, THE TERMS OF THIS PARAGRAPH SHALL NOT APPLY TO (A) SPECIFIC CLAIMS MADE PURSUANT TO ANY OTHER PROVISION OF THIS AGREEMENT, INCLUDING WITHOUT LIMITATION, IN RESPECT OF BREACH OF REPRESENTATIONS OR WARRANTIES, (B) ANY CLAIMS ARISING OUT OF GROSS NEGLIGENCE, FRAUD, WILLFUL

![](purchasandsaleagreementa007.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;MISCONDUCT, OR ILLEGAL ACTS OF SELLER OR OF ANY SELLER RELATED PARTY, AND (C) TORT CLAIMS RELATED TO THE PERIOD PRIOR TO CLOSING. THE TERMS AND PROVISIONS OF THIS SECTION 2.4 SHALL SURVIVE THE CLOSING. ARTICLE III CLOSING 3.1 Time and Place. The parties shall conduct an escrow closing (the "Closing") on the later to occur of (i) December 11, 2025 or (ii) the date that is two (2) business days after Seller shall have received the Fully Executed First Amendment (as defined in Section 3.6(f) below) and the Fully Executed Letter Agreement Assignment (as defined in Section 3.6(h) below), unless mutually agreed to a later date in writing by the parties (such later date pursuant to preceding clause (i) and clause (ii), the "Closing Date"), but in no event shall the Closing Date be later than December 19, 2025 (the "Outside Closing Date"), unless this Agreement has terminated pursuant to Section 2.3(b) above or Purchaser and Seller have agreed in writing in their respective sole and absolute discretion to conduct the Closing prior to such date. If the Closing does not occur on the Closing Date or by 5:00 pm Eastern time on the Outside Closing Date, the Title Company shall, unless it is notified by both Seller and Purchaser in writing to the contrary within five (5) business days after the Closing Date, return to the depositor thereof items other than the Deposit (which will remain in escrow pending the earlier of (x) receipt of a written direction notice signed by both Purchaser and Seller or (y) the delivery to the Escrow Holder of a judgment of a court of competent jurisdiction directing disposition of the Deposit (except that if such judgment has been stayed pending appeal, then Escrow Holder shall retain the Deposit pending the final resolution of such appeal); provided that nothing herein shall prevent the Escrow Holder from depositing the Deposit with a court of competent jurisdiction in accordance with court procedure to the extent a litigation in respect of this Agreement has been filed at such court) which were deposited thereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;successor or assign) shall have actually delivered and shall actually be making available electrical capacity to the Property in excess of sixty (60) MW (each such event, an "Additional Energization" and the date on which such event occurs, an "Additional Energization Date"), Purchaser or its successor or assign ("Obligee") shall pay Seller the sum of ONE HUNDRED AND EIGHTY THOUSAND DOLLARS ($180,000) per MW of electrical capacity in excess of sixty (60) MW (each such payment, a "Success Payment," and collectively, the "Success Payments") in cash by wire transfer of immediately available federal funds to a bank account designated by Seller. Seller acknowledges and agrees that Seller shall only be entitled to a Success Payment if (and only if) the Post-Closing Power Condition and the applicable Additional Energization(s) occur during the Ramp-up Period. The Success Payments paid to the Seller in the aggregate shall not exceed EIGHTEEN MILLION DOLLARS ($18,000,000) (the "Success Payment Cap"). If Seller is entitled to a Success Payment during the Ramp-Up Period, Purchaser shall deliver such Success Payment to Seller within three (3) months of the corresponding Additional Energization Date. For example, if Duke Energy delivered (i) an additional 30 MW of electrical capacity (for a total of 90 MW of electrical capacity) in an Additional Energization on January 1, 2028, and (ii) an additional 70 MW of electrical capacity (for a total of 160 MW of electrical capacity) in an Additional Energization on January 1, 2030, then Purchaser would pay Seller (x) a Success Payment of $5,400,000 on or before April 1, 2028 for the 30 MW Additional Energization, and (y) a Success Payment of $12,600,000 on or before April 1, 2030 for the 70 MW Additional Energization, for a total Success Payment of $18,000,000. As security for the Obligee's obligation to make Success Payments for Additional Energizations during the Ramp-Up Period, Purchaser shall cause Lightstone Parent LLC, a Delaware limited liability company, which is an affiliate of Purchaser ("Joinder Party"), to execute the Joinder attached hereto. The provisions of this Section 8.21 shall survive the Closing, shall run with the land, and be binding on Purchaser's successors and assigns. [SIGNATURES ON FOLLOWING PAGE]
