 We are a public accounting
firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect
to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange
Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.
Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free
of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit
of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control
over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control
over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures
included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included
evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation
of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from
the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that:
(1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective,
or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the financial statements,
taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit
matter or on the accounts or disclosures to which it relates.

Accounting for and fair value of the Induced Warrant Exercise

As discussed in Notes 2 and 10 to the financial statements, in October
2024, the Company recorded a deemed dividend of $7.8 million for the issuance of warrants to purchase shares of Company common stock (New
Warrants) in exchange for the exercise of certain existing warrants (the Induced Warrant Exercise), which was included in the net loss
attributable to Class A
