Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Cardiff Lexington Corporation (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of operations, stockholders’ (deficit) equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Continuation as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in the notes to the consolidated financial statements, the Company has experienced recurring losses from operations and negative cash flows from operations 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 the notes. 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 the Company’s 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 critical audit matters 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 separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Estimates of Variable Consideration Related to Healthcare Revenue

Description of the Matter

As described in the notes to the consolidated financial statements, the Company recognizes revenue, net that includes estimates of variable consideration. For the year ended December 31, 2025, the Company recorded healthcare revenue, net of $11.5 million. The components of variable consideration include (a) settlement discounts relative to gross billings for procedures performed, and (b) price concessions to generate settlements and cash inflows. These estimates take into consideration established billing rates (gross charges); historical collection rates, including established charges per procedure with guidance from the annually updated Current Procedural Terminology (“CPT”) guidelines that designates relative value units and a suggested range of charges for each procedure which is then assigned a CPT code, modifiers recognized by each insurance carrier for services, less deductible, co-pay, and contractual adjustments, as well as current settlement realization rates with payors based on discussions with doctors and attorneys and the third-party medical billing company vendor.

Auditing management's estimates for variable consideration required subjective auditor judgment and evaluation of the reasonableness of significant assumptions used in developing the estimates as detailed above, as well as the inputs and related calculations related to current contracts.

How We Addressed the Matter in Our Audit

We obtained an understanding and evaluated the design of internal controls over the Company's calculations to estimate variable consideration, including management's assessment of the assumptions and data underlying the reserve calculation.

Our substantive audit procedures included, among others, (i) testing management’s process for developing the estimates of variable consideration, (ii) testing the completeness and accuracy of underlying data used in the method on a sample basis, and (iii) evaluating the reasonableness of management’s significant assumption related to the period of historical experience. Evaluating the reasonableness of the assumption related to the period of historical experience involved considering the historical relationships of revenue recognized and subsequently collected, and whether this assumption was consistent with evidence obtained in other areas of the audit. Further, we evaluated the appropriateness of classification and disclosure of the Company’s reserves for variable consideration in the consolidated financial statements.
