Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

(a)

On December 19, 2025, Dyadic International, Inc. (the “Company”) received a deficiency notice (the “Notice”) from the Nasdaq Listing Qualifications staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that for the last 30 consecutive business days the Company’s securities have not maintained the minimum bid price of at least $1 per share required by the continued listing requirements of Nasdaq Listing Rule 5550(a)(2). The Notice has no immediate effect on the listing of the Company’s common stock on the Nasdaq Capital Market. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has 180 calendar days, or until June 17, 2026 (the “Compliance Date”), to regain compliance with the minimum bid price requirement by having the Company’s bid price close at $1 per share or more for a minimum of 10 consecutive business days before the Compliance Date (subject to the Staff’s discretion to extend this period under Nasdaq Listing Rule 5810(c)(3)(H)). If the Company does not regain compliance by the Compliance Date, the Company may be eligible for an additional 180-day period to regain compliance, provided that on the Compliance Date the Company meets the applicable market value of publicly held shares requirement for continued listing and all other applicable standards for initial listing on the Nasdaq Capital Market (except the bid price requirement) based on the Company’s most recent public filings and market information and provides Nasdaq with written notice of its intent to cure this deficiency. However, if it appears to the Staff that the Company will not be able to cure the deficiency, or if the Company is otherwise not eligible for the second compliance period, and the Company does not regain compliance by the Compliance Date, the Staff will provide written notification that the Company’s common stock is subject to delisting. At that time, the Company may appeal the delisting determination to a hearings panel pursuant to the procedures set forth in the applicable Nasdaq listing rules. However, there can be no assurance that, if the Company receives a delisting notice and appeals the delisting determination by Nasdaq to the panel, such appeal would be successful.

The Company intends to actively monitor the bid price of its common stock between now and the Compliance Date and, as appropriate, plans to evaluate available options to resolve the deficiency and regain compliance with the minimum bid price requirement.
