Exhibit 3.1

CERTIFICATE OF AMENDMENT TO

THE AMENDED AND RESTATED CERTIFICATE OF INCORPORATION OF

Professional Diversity Network, Inc.

Professional Diversity Network, Inc., a corporation organized and existing under and by virtue of the General Corporation Law of the State of Delaware (the “Company”), does hereby certify as follows:

1. The name of the Company is Professional Diversity Network, Inc., and the Company was originally incorporated pursuant to the General Corporation Law on ‎January 31, 2012.

2. The Amended and Restated Certificate of Incorporation of the Company (the “Certificate of Incorporation”) is hereby amended as follows:

Article IV of the Certificate of Incorporation is hereby deleted in its ‎entirety and replaced with the following:‎

4. Stock

4.1 Classes of Stock. The Corporation is authorized to issue two classes of stock to be designated, respectively, common stock (“Common Stock”) and preferred stock (“Preferred Stock”). The total number of shares of all classes of stock that the Corporation is authorized to issue is 46,000,000.

4.2 Common Stock. The total number of shares of Common Stock that the Corporation shall have authority to issue is 45,000,000 shares, $0.01 par value per share. The number of authorized shares of Common Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the affirmative vote of the holders of a majority of the total voting power of the outstanding shares of capital stock of the Corporation entitled to vote, irrespective of the provisions of Section 242(b)(2) of the General Corporation Law or any corresponding provision hereinafter enacted.

Effective as of 12:01 am on January 5, 2023 (the “Effective Time”), each two (2) shares of Common Stock issued and outstanding immediately prior to the Effective Time shall be combined and changed into one (1) validly issued, fully paid, and non-assessable share of Common Stock without any further action by the Corporation or any holder thereof, subject to the treatment of fractional share interests as described below (the “Reverse Stock Split”). No certificates representing fractional shares of Common Stock shall be issued in connection with the Reverse Stock Split. Stockholders who otherwise would be entitled to receive fractional shares of Common Stock because they hold a number of shares not evenly divisible by the Reverse Stock Split ratio will instead be entitled to receive a cash payment in lieu of such fractional shares. The cash ‎payment to be paid will be in an amount equal to the relevant percentage of the amount received per share upon ‎the sale in one or more open market transactions of the aggregate of all such fractional shares.‎ Each certificate that immediately prior to the Effective Time represented shares of Common Stock (“Old Certificates”), shall thereafter represent that number of shares of Common Stock into which the shares of Common Stock represented by the Old Certificate shall have been combined.

4.3 Preferred Stock. The total number of shares of Preferred Stock that the Corporation shall have authority to issue is 1,000,000 shares, $0.01 par value per share. The Preferred Stock may be issued from time to time in one or more series. The Board of Directors is hereby authorized, within the limitations and restrictions stated in the Corporation’s Certificate of Incorporation, as amended as restated (the “Charter”), to provide for the issue of all or any of the shares of Preferred Stock in one or more series, and to fix the number of shares and to determine or alter for each such series, such voting powers, full or limited, or no voting powers, and such designations, preferences and relative, participating, optional, or other rights and such qualifications, limitations, or restrictions thereof, as shall be stated and expressed in the resolution or resolutions adopted by the Board of Directors providing for the issue of such shares and as may be permitted by the General Corporation Law. The Board of Directors is also authorized to increase or decrease the number of shares of any series of Preferred Stock subsequent to the issue of shares of that series, but not below the number of shares of such series then outstanding. In case the number of shares of any series shall be so decreased, the shares constituting such decrease shall resume the status of which they had prior to the adoption of the resolution originally fixing the number of shares of such series.

3. This Amendment of the Certificate of Incorporation herein certified has been duly adopted and written consent has been given in accordance with the provisions of Sections 228 and 242 of the General Corporation Law of the State of Delaware.

IN WITNESS WHEREOF, the Company has caused this Certificate of Amendment to be signed as of January 3, 2023.
