Professional Diversity Network Announces 1-for-30 Reverse Stock Split

CHICAGO, September 10, 2026 - Professional Diversity Network, Inc. (NASDAQ: IPDN) (the "Company") today announced that it will effect a 1-for-30 reverse stock split of its outstanding common stock.

The reverse stock split is expected to become effective at 5:30 p.m. Eastern Time on September 11, 2026, and the Company's common stock is expected to begin trading on a split-adjusted basis on the Nasdaq Capital Market at the opening of trading on September 14, 2026.

The Company's common stock will continue to trade under the ticker symbol "IPDN" and will trade under a new CUSIP number following the effectiveness of the reverse stock split.

At the effective time, every 30 shares of the Company's issued and outstanding common stock will automatically be consolidated into one share of common stock. The reverse stock split will not change the total number of shares of capital stock that the Company is authorized to issue.

No fractional shares will be issued in connection with the reverse stock split. Any fractional share resulting from the reverse stock split will be rounded up to the nearest whole share. Based on the 19,974,323 shares of common stock issued and outstanding as of September 9, 2026, approximately 665,811 shares of common stock are expected to be issued and outstanding immediately following the reverse stock split, subject to adjustment as a result of the rounding of fractional shares.

The reverse stock split will apply uniformly to all holders of the Company's common stock and will not alter any stockholder's percentage ownership interest in the Company, except for immaterial adjustments that may result from the treatment of fractional shares.

The Company's transfer agent, Transhare Corporation, will act as the exchange agent in connection with the reverse stock split. Stockholders holding shares electronically in book-entry form or through a bank, broker or other nominee will have their shares adjusted automatically to reflect the reverse stock split, subject to the treatment of fractional shares described above.
