Comparison to Industry Standards

• The material weakness reported by Marcum is a concern, as it indicates a deficiency in the company's internal controls over financial reporting.
• Companies like Marathon Digital Holdings and Riot Platforms, also in the Bitcoin mining space, are expected to maintain robust internal controls due to the complex nature of digital asset accounting.

Stakeholder Impact

• Shareholders should be aware of the change in auditors and the disclosed material weakness in internal control.
• The company's management will need to work with CBIZ to ensure a smooth transition and address the identified material weakness.
