Professional Diversity Network Inc. recently announced a change in its certifying accountant following the resignation of its independent registered public accounting firm, Sassetti LLC. The resignation, effective July 24, 2025, was due to scheduling conflicts and resource constraints, rather than any issues related to the Company's audit. The Board of the Company did not influence this decision. During the two most recent fiscal years and the interim period prior to the engagement of a new firm, there were no disagreements or reportable events between the Company and Sassetti concerning accounting principles, financial statement disclosure, or auditing procedures.
