Professional Diversity Network, Inc.

Current report

We have been notified by Nasdaq of our failure to comply with certain continued listing requirements and, if we are unable to regain or maintain compliance with all applicable continued listing requirements and standards of Nasdaq, our common stock could be delisted from the Nasdaq Capital Market.

Current report

Our common stock, par value $0.0001 per share (“Common Stock”) is currently listed on The Nasdaq Stock Market LLC (“Nasdaq”). In order to maintain that listing, we must satisfy minimum financial and other continued listing requirements and standards, including those regarding director independence and independent committee requirements, minimum stockholders’ equity, minimum share price, and certain corporate governance requirements.

Current report

On June 5, 2026, we received a written notification from Nasdaq notifying us that we were not in compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market, as set forth under Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”), because the closing bid price of our shares of Common Stock was below $1.00 per share for the previous thirty (30) consecutive business days. We were granted 180 calendar days, or until December 2, 2026, to regain compliance with the Minimum Bid Price Requirement. In the event we do not regain compliance with the Minimum Bid Price Requirement by December 2, 2026, we may be eligible for an additional 180-calendar day grace period. To qualify, we will be required to meet the continued listing requirement for market value of publicly held shares and all other listing standards for Nasdaq, with the exception of the Minimum Bid Price Requirement, and will need to provide written notice to Nasdaq of our intent to regain compliance with such requirement during such second compliance period. If we do not regain compliance within the allotted compliance period(s), including any extensions that may be granted, Nasdaq will provide notice that our Common Stock will be subject to delisting from Nasdaq. At that time, we may appeal Nasdaq’s determination to a hearings panel.

Current report

The Company intends to continuously monitor the closing bid price for its Common Stock, and is in the process of considering various measures to resolve the deficiency and regain compliance with the Minimum Bid Price Requirement. On July 13, 2026, the Company held a Special Meeting of Stockholders at which the Company’s stockholders approved an amendment to the Company’s amended and restated certificate of incorporation (the “Certificate of Incorporation”) to effect a reverse stock split of the Company’s outstanding shares of Common Stock at a ratio ranging from one‑for‑two (1‑for‑2) to one‑for‑two thousand (1‑for‑2000), with the exact ratio to be determined by the Company’s Board of Directors in its sole discretion. The Board may effect the reverse stock split at any time within one year following stockholder approval. However, there can be no assurance that we will be able to regain or maintain compliance with the Minimum Bid Price Requirement or any other Nasdaq listing standards, that Nasdaq will grant the Company any extension of time to regain compliance with the Minimum Bid Price Requirement or any other Nasdaq listing requirements, or that any such appeal to the Nasdaq hearings panel will be successful, as applicable. If we are unable to maintain compliance with these Nasdaq requirements, our Common Stock will be delisted from Nasdaq.

Current report

In addition, on July 22, 2026, the SEC approved a Nasdaq rule change requiring the immediate suspension and delisting of any listed company whose market value of listed securities (“MVLS”) falls below $5 million for 30 consecutive business days, subject to limited review by a Nasdaq Hearings Panel. Under the approved rule, a timely request for a hearing will not stay the suspension of trading, and our securities would generally trade on the over-the-counter market during any appeal process. The Nasdaq Hearings Panel may grant a limited exception period (not to exceed 180 days) to demonstrate compliance with initial listing requirements, but there can be no assurance that such relief would be granted.

Current report

Our ability to maintain compliance with the $5 million MVLS requirement depends on a number of factors, including the market price of our Common Stock and the number of our issued and outstanding shares. The market price of our Common Stock may be volatile and could decline for reasons beyond our control, including:

Current report

● general market conditions or downturns in the broader equity markets;

Current report

● sector-specific or industry-wide volatility;

Current report

● changes in interest rates or macroeconomic conditions;

Current report

● geopolitical events;

Current report

● actual or perceived short selling activity or other trading dynamics;

Current report

● reduced liquidity or limited public float; and

Current report

● investor perceptions regarding our business, prospects, or financial condition.

Current report

If our MVLS were to fall below $5 million for 30 consecutive business days, Nasdaq would issue a staff delisting determination and immediately suspend trading of our Common Stock on Nasdaq. Any suspension or delisting of our Common Stock from Nasdaq could materially and adversely affect our business, financial condition, results of operations, and the value of our Common Stock.

Current report

In the event that our Common Stock is delisted from Nasdaq, as a result of our failure to comply with the Minimum Bid Price Requirement, or due to our failure to continue to comply with any other requirement for continued listing on Nasdaq, and is not eligible for listing on another exchange, trading in the shares of our Common Stock could be conducted in the over-the-counter market or on an electronic bulletin board established for unlisted securities such as the Pink Sheets or the OTC Bulletin Board. In such event, it could become more difficult to dispose of, or obtain accurate price quotations for, our Common Stock, and it would likely be more difficult to obtain coverage by securities analysts and the news media, which could cause the price of our Common Stock to decline further. Also, it may be difficult for us to raise additional capital if we are not listed on a national exchange.

Current report

In the event that our Common Stock is delisted from Nasdaq, U.S. broker-dealers may be discouraged from effecting transactions in shares of our Common Stock because they may be considered penny stocks and thus be subject to the penny stock rules.

Current report

The U.S. Securities and Exchange Commission (the “SEC”) has adopted a number of rules to regulate “penny stock” that restricts transactions involving stock which is deemed to be penny stock. Such rules include Rules 3a51-1, 15g-1, 15g-2, 15g-3, 15g-4, 15g-5, 15g-6, 15g-7, and 15g-9 under the Exchange Act. These rules may have the effect of reducing the liquidity of penny stocks. “Penny stocks” generally are equity securities with a price of less than $5.00 per share (other than securities registered on certain national securities exchanges or quoted on Nasdaq if current price and volume information with respect to transactions in such securities is provided by the exchange or system). Our shares of Common Stock have in the past constituted, and may again in the future constitute, “penny stock” within the meaning of the rules. The additional sales practice and disclosure requirements imposed upon U.S. broker-dealers may discourage such broker-dealers from effecting transactions in shares of our Common Stock, which could severely limit the market liquidity of such shares of Common Stock and impede their sale in the secondary market.

Current report

Future sales or issuances of our Common Stock, including shares issuable upon exercise of the warrants issued in our August 2026 public offering, may result in substantial dilution and could adversely affect the market price of our Common Stock.

Current report

On August 13, 2026, we completed a best-efforts public offering in which we sold 1,620,000 units at a public offering price of $0.28 per unit and 5,524,000 pre-funded units at a public offering price of $0.2799 per pre-funded unit. Each unit consisted of one share of our Common Stock and one common stock purchase warrant, and each pre-funded unit consisted of one pre-funded common stock purchase warrant and one common stock purchase warrant. We received gross proceeds of approximately $2.0 million before deducting placement agent fees and other offering expenses.

Current report

The offering resulted in the issuance of 1,620,000 shares of Common Stock and warrants to purchase an aggregate of up to 12,668,000 additional shares of Common Stock, consisting of pre-funded warrants to purchase up to 5,524,000 shares and Common Stock purchase warrants to purchase up to 7,144,000 shares. The exercise of these warrants would increase the number of shares of our Common Stock outstanding and dilute the ownership interests and voting power of our existing stockholders.

Current report

The issuance of a substantial number of shares upon exercise of these warrants, or the perception that such issuances may occur, could adversely affect the market price of our Common Stock. The outstanding warrants may also create an overhang on the market for our Common Stock and may make it more difficult for us to raise additional capital on favorable terms. Warrant holders may exercise their warrants at times when we could otherwise obtain more favorable terms in a new equity financing, and the availability of shares for issuance upon exercise may discourage potential investors from purchasing our Common Stock.

Current report

We may need to raise additional capital to support our operations and strategic initiatives. We may do so through additional issuances of Common Stock, preferred stock, convertible securities, warrants or other equity-linked securities. Any such future issuance could result in additional and potentially substantial dilution to our existing stockholders, may include rights or preferences senior to those of our Common Stock, and could further adversely affect the market price of our Common Stock.
