B. Riley Financial, Inc. (the “Company”) is providing this disclosure to explain the facts and circumstances, as well as Marcum LLP’s (“Marcum”) and the Audit Committee’s conclusions, concerning Marcum’s objectivity and impartiality with respect to the completion of the AS 41015: Reviews of Interim Financial Information for the periods ended June 30, 2024 and September 30, 2024 and the fiscal year ended December 31, 2024 integrated audit of the Company.

On November 1, 2024, CBIZ, Inc. (“CBIZ”) completed the acquisition of substantially all of the non-attest business assets of Marcum and CBIZ CPAs P.C. purchased substantially all of Marcum’s attest business assets (the “Transaction”).

Prior to the Transaction close, Marcum informed the Company that it would not be independent with respect to the completion of interim reviews and annual integrated audit for the fiscal year ended December 31, 2024 as a result of certain non-attest services that were performed by CBIZ (bookkeeping and management functions) during the period under audit for affiliates of the Company upon closing of the proposed Transaction. The affiliated entities were managed by an unrelated third party, which retained CBIZ for these services.

For the following reasons, the Audit Committee of the Board of Directors of the Company and Marcum have each concluded, and are of the view that a reasonable investor with knowledge of all relevant facts and circumstances would conclude, that the provision of these services did not impair Marcum’s objectivity and impartiality with respect to Marcum’s review of interim financial information and the integrated audit of the Company’s financial statements and internal controls over financial reporting:

1. CBIZ performed the non-attest services (bookkeeping and management functions), which ceased prior to the Transaction close.

2. The non-attest services performed by CBIZ were routine or mechanical in nature, did not involve making management decisions and did not have a material impact on the consolidated financial statements of the Company. The fees earned by CBIZ were insignificant to both CBIZ and the Company.

3. The Marcum audit engagement team had no interaction with the CBIZ non-attest services team in the conduct of their audit and reviews. No personnel from CBIZ who worked on the non-attest service will be part of the audit team or have any involvement in the audit.

4. Effective October 25, 2024, the Company’s majority owned subsidiary bebe stores, inc. sold its interest in two of the affiliated entities to a joint venture with third parties and no longer has an ownership interest. See the accompanying financial statements Note 21 – Subsequent Events for further discussion on this transaction. On October 25, 2024, the Company also entered into a secured financing transaction with a joint venture between third parties for the other affiliated entities which resulted in the deconsolidation of these entities with the Company retaining an insignificant residual ownership interest. See the accompanying financial statements Note 21 – Subsequent Events for further discussion on this transaction.
