Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, have conducted an

evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e)

and 15d-15(e) under the Exchange Act) as of March 31, 2026.

Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of March 31,

2026, our disclosure controls and procedures were not effective due to the material weakness in internal control over financial

reporting described below.

As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025, we identified a material

weakness in our internal control over financial reporting.

As of March 31, 2026, this material weakness has not been remediated.

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable

assurance of achieving the desired control objectives.

Our management recognizes that any control system, no matter how well

designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurances that its objectives

Similarly, an evaluation of controls cannot provide absolute assurances that misstatements due to error or fraud will not

occur or that all control issues and instances of fraud, if any, have not been detected.

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, have conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of June 30, 2026.

Based on that evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of June 30, 2026, our disclosure controls and procedures were not effective due to the material weakness in internal control over financial reporting described below.

As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2025, we identified a material weakness in our internal control over financial reporting.

Our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving the desired control objectives.

Our management recognizes that any control system, no matter how well designed and operated, is based upon certain judgments and assumptions and cannot provide absolute assurances that its objectives will be met.

Similarly, an evaluation of controls cannot provide absolute assurances that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have not been detected.

Material Weakness in Internal Control over Financial Reporting

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there

is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected

on a timely basis.

The material weakness previously identified and which remains unremediated as of March 31, 2026 is as follows:

We did not effectively operate controls to account for intended demolition of building and infrastructure assets, including

evaluation of impairment, related to the conversion of facilities from digital asset mining operations to HPC colocation infrastructure

due to insufficient complement of trained personnel.

This material weakness resulted in material misstatements to property, plant and equipment on the consolidated balance sheet

and impairment of property, plant and equipment on the consolidated statement of operations, which were corrected prior to the

issuance of the consolidated financial statements as of and for the year ended December 31, 2025, however, resulted in the restatement

of previously issued annual and interim financial statements.

The control deficiency described above created a reasonable possibility

that a material misstatement of the consolidated financial statements will not be prevented or detected on a timely basis, we concluded

the deficiency represents a material weakness in our internal control over financial reporting and our internal control over financial

reporting was determined to be not effective as of December 31, 2025 and continues to be not effective as of March 31, 2026.

Remediation Plan for the Material Weakness

With the oversight of senior management and the Audit Committee, we have developed a remediation plan to address the

material weakness.

With the oversight of senior management and the Audit Committee, we have developed a remediation plan to address the material weakness.

The plan includes the elements described below, which we are in various stages of implementing.

• Implementing additional training for accounting personnel on the evaluation of novel transactions related to property,

plant and equipment.

During the three months ended March 31, 2026, we conducted training for accounting personnel

on the identification of novel and non-routine transactions.

• Implementing additional levels of management review and oversight, including consultation with external technical

accounting resources as necessary, over significant accounting conclusions related to property, plant and equipment,

including those involving the application of accounting guidance to novel or non-routine transactions.

During the three

months ended March 31, 2026, we implemented a quarterly management review process for property, plant and

equipment and established an accounting policy review committee.

We believe our remediation plan will be sufficient to remediate the material weakness.

However, the material weakness will not

be considered remediated until management completes the design and implementation of the actions described above and the controls

operate for a sufficient period of time, and management has concluded, through testing, that these controls are effective.

As we test our

internal controls over financial reporting, we may determine that additional measures or modifications to the remediation plan are

necessary or appropriate.

• Implementing additional training for accounting personnel on the evaluation of novel transactions related to property, plant and equipment.

During the six months ended June 30, 2026, we conducted training for accounting personnel on the identification of novel and non-routine transactions and completed an assessment of the scope of property, plant and equipment transactions subject to enhanced review procedures during the period.

• Implementing additional levels of management review and oversight, including consultation with external technical accounting resources as necessary, over significant accounting conclusions related to property, plant and equipment, including those involving the application of accounting guidance to novel or non-routine transactions.

During the six months ended June 30, 2026, we implemented a quarterly management review process for property, plant and equipment and established an accounting policy review committee.

During the first and second quarter of 2026, the accounting policy review committee met and completed review of the Company’s application of accounting guidance to non-routine transactions and accounting policies and concluded that no policy changes were required.

We believe our remediation plan will be sufficient to remediate the material weakness upon the completion of the annual assessment of internal control over financial reporting as of December 31, 2026.

However, the material weakness will not be considered remediated until management completes the design and implementation of the actions described above and the controls operate for a sufficient period of time, and management has concluded, through testing, that these controls are effective.

As we test our internal controls over financial reporting, we may determine that additional measures or modifications to the remediation plan are necessary or appropriate.
