Stratum Holdings Corp.

During the years ended December 31, 2024 and 2023, we engaged Marcum LLP as our independent registered accounting firm. For the years ended December 31, 2024 and 2023, we incurred fees, as discussed below:

In the above table, “audit fees” are fees billed for services provided related to the audit of our annual financial statements, quarterly reviews of our interim financial statements, and services normally provided by the independent accountant in connection with regulatory filings or engagements for those fiscal periods. “Audit-related fees” are fees not included in audit fees that are billed by the independent accountant for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements. These audit-related fees also consist of the review of our registration statements filed with the SEC and related services normally provided in connection with regulatory filings or engagements. “Tax Fees” are fees primarily for tax compliance in connection with filing US income tax returns. “All other fees” are fees billed by the independent accountant for products and services not included in the foregoing categories.

Audit Committee Pre-Approval Policies

The charter of our Audit Committee provides that the duties and responsibilities of our Audit Committee include the pre-approval of all audit and non-audit services permitted by law or applicable SEC regulations (including fee and terms of engagement) to be performed by our external auditor.

All of the services provided above under the caption “Audit-Related Fees” were approved by our Board of Directors or by our Audit Committee pursuant to our Audit Committee’s pre-approval policies.
