REPORT
OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To
the Stockholders and Board of Directors
Sonnet
BioTherapeutics Holdings, Inc. and Hyperliquid Strategies, Inc.:
Opinion
on the Consolidated Financial Statements
We
have audited the accompanying consolidated balance sheets of Sonnet BioTherapeutics Holdings, Inc. and subsidiaries (the Company) as
of September 30, 2025 and 2024, the related consolidated statements of operations, stockholders’ equity (deficit), and cash flows
for the years then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated
financial statements present fairly, in all material respects, the financial position of the Company as of September 30, 2025 and 2024,
and the results of its operations and its cash flows for the years then ended, in conformity with U.S. generally accepted accounting
principles.
Going
Concern
The
accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed
in Note 1 to the consolidated financial statements, the Company has incurred recurring losses and negative cash flows from operations
since inception that will require substantial additional financing to continue to fund its research and development activities that raise
substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described
in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.
Basis
for Opinion
These
consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion
on these consolidated financial statements based on our audits. 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 consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated 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 consolidated 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.
Accrued
research and development expense
As
discussed in Notes 2 and 3 to the consolidated financial statements, research and development costs are expensed as incurred, which include
amounts due to third parties for research, development, and manufacturing services. At the end of each reporting period, the Company
compares the payments made to third-party service providers to the estimated progress towards completion of the related project, based
on the measure of progress as defined in the contract. Factors the Company considers in preparing the estimates include costs incurred
by the service provider, milestones achieved, and other criteria related to the efforts of its service providers. Depending on the timing
of payments to the third-party service providers and the progress the Company estimates has been made as a result of the services provided,
the Company will record a prepaid expense or accrued liability related to these costs. As of September 30, 2025, the Company reported
accrued research and development expenses of $0.6 million.
We
identified the evaluation of certain accrued research and development expenses for third-party service providers as a critical audit
matter. Evaluating the estimated progress toward completion of research and development projects, including the factors described above,
required especially subjective auditor judgment.
The
following are the primary procedures we performed to address this critical audit matter. To evaluate the Company’s estimate of
costs incurred as of September 30, 2025, for a selection of accrued research and development expenses, we (1) examined the provisions
in the contracts, invoices and communications received from third party service providers related to the project status; (2) sent confirmations
to the third-party service providers; and (3) inquired of the individuals who are responsible for monitoring and tracking the status
of research and development activities.
