On August 15, 2025, Soligenix, Inc. (the "Company") received notice (the "Notice") from The Nasdaq Stock Market LLC ("Nasdaq") advising the Company that it is not in compliance with the minimum stockholders' equity requirement for continued listing on The Nasdaq Capital Market. Nasdaq Listing Rule 5550(b)(1) requires companies listed on The Nasdaq Capital Market to maintain stockholders' equity of at least $2,500,000 (the "Stockholders' Equity Requirement"). In the Company's Quarterly Report on Form 10-Q for the quarter ended June 30, 2025, the Company reported stockholders' equity of $1,828,951, which is below the Stockholders' Equity Requirement for continued listing. This amount does not reflect sales activity under the Company's At-The-Market ("ATM") facility on July 1, 2025, which generated total gross proceeds of approximately $1,439,300. Additionally, as of the date of this report, the Company does not meet either of the alternative Nasdaq continued listing standards under the Nasdaq Listing Rules, market value of listed securities of at least $35 million, or net income of $500,000 from continuing operations in the most recently completed fiscal year, or in two of the three most recently completed fiscal years.

The Notice has no immediate effect on the listing of the Company's common stock and the Company's common stock continues to trade on The Nasdaq Capital Market under the symbol "SNGX," subject to the Company's compliance with the other continued listing requirements.

Pursuant to the Notice, Nasdaq has given the Company 45 calendar days, or until September 29, 2025, to submit to Nasdaq a plan to regain compliance. If the Company's plan is accepted, Nasdaq may grant an extension of up to 180 calendar days from the date of the Notice to evidence compliance.

The Company is currently evaluating various courses of action to regain compliance and plans to timely submit its plan to Nasdaq to regain compliance with the Stockholders' Equity Requirement. There can be no assurance that the Company's plan will be accepted or that if it is, the Company will be able to regain compliance. If the Company's plan to regain compliance is not accepted, or if it is and the Company does not regain compliance within 180 days from the date of Nasdaq's letter, or if the Company fails to satisfy another Nasdaq requirement for continued listing, Nasdaq could provide notice that the Company's common stock will become subject to delisting. In such event, Nasdaq rules would permit the Company to appeal the decision to reject the Company's proposed compliance plan or any delisting determination to a Nasdaq Hearings Panel. The hearing request would stay any suspension or delisting action pending the conclusion of the hearing process and the expiration of any additional extension period granted by the panel following the hearing.
