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

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk.

Definition and Limitations of Internal Control Over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

To the Stockholders and the Board of Directors of Medifast, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Medifast, Inc. (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations, comprehensive income, changes in stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated February 17, 2026, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with 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. 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) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the 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 separate opinions on the critical audit matter or on the accounts or disclosures to which they relate.

Income Taxes

As described in Notes 2 and 11 of the financial statements, the Company operates in multiple markets in the U.S. using an e‑commerce platform and a direct selling network of OPTAVIA coaches. Management prepared the Company’s provision for income taxes using significant judgment when interpreting the provisions of federal, state and local tax regulations. Significant judgment is placed on both the assessment of whether it is more likely than not that some or all the Company's deferred tax assets will be realized and whether the amount of benefit recorded would more likely than not be sustained upon examination. As disclosed in Note 11 of the financial statements, the Company recorded a valuation allowance of $12.1 million during the year ended December 31, 2025 and as of December 31, 2025, the Company had $5.6 million of gross unrecognized tax benefits.

We identified the evaluation of the Company’s provision for income taxes as a critical audit matter due to the significant judgments made by management when assessing the complex provisions of the tax laws and regulations. Auditing the matter required significant auditor judgment and increased audit effort, including use of our tax specialists, in evaluating the recorded results of management’s tax positions and their assessment of the sustainability of these tax positions.

Our audit procedures related to the Company’s provision for income taxes included the following, among others:

•We obtained an understanding of the relevant controls related to the determination of current and deferred taxes and tested such controls for design and operating effectiveness, including controls related to the interpretation and application of tax laws.

•We evaluated the reasonableness of management's estimates in regard to the ability to realize deferred tax assets by testing management's assessment of the ability to generate sufficient taxable income and the timing of future reversals of temporary differences.

•We utilized personnel with specialized knowledge and skill in income taxes and accounting for income taxes:

◦to assist in the evaluation of management's assessment of positive and negative evidence and their conclusion that it is more likely than not that the Company will not realize the benefit of its deferred tax assets.

◦to assist in evaluating the application and sustainability of federal regulations and state and local tax positions.

•We tested the accuracy and completeness of the data and inputs used to calculate the effective federal and state tax rates, current provision calculations and deferred tax assets and liabilities.
