Notice

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

(a)

On

March 27, 2026, Dyadic International, Inc. (the “Company” or “Dyadic”) 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 it is out of compliance with the technical minimum requirements for continued listing under Nasdaq Listing Rule 5550(b)

(the “Continued Listing Requirement”). The Continued Listing Requirement requires the Company to maintain at least one of

the following: $2.5 million in stockholders’ equity; $35 million in market value of listed securities; or $500,000 of net income

from continuing operations. The Notice has no immediate effect on the listing of the Company’s common stock on the Nasdaq Capital

Market. In accordance with Nasdaq rules, the Company has 45 calendar days, or until May 11, 2026, to submit a plan to regain compliance

with any of the three minimum requirements under the Continued Listing Requirement. If the plan is accepted, the Company may be eligible

for a cure period of up to 180 days from March 27, 2026 (September 23, 2026) to regain compliance. If the plan is not accepted, the Company

may appeal the determination to a hearings panel pursuant to the procedures set forth in the applicable Nasdaq listing rules. There can

be no assurance that, if the Company decides to appeal the determination by Nasdaq to the panel, such appeal would be successful.

The

Company intends to actively monitor its compliance with the Continued Listing Requirement an ongoing basis and, as appropriate, plans

to evaluate available options to resolve the deficiency and regain compliance (likely through the $2.5 million in stockholders’

equity requirement).

As

previously disclosed, the Company also remains out of compliance with the minimum bid price of $1.00 required by the continued listing

requirements of Nasdaq Listing Rule 5550(a)(2), and has until June 17, 2026 to regain compliance with such requirement. The Continued

Listing Requirement deficiency discussed in the Notice is a separate and unrelated deficiency, and either deficiency, if not cured by

the applicable deadline, could be a basis for the delisting of the Company’s common stock.

Harbor Regarding Forward-Looking Statements

current report on Form 8-K contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended,

and Section 21E of the Securities Exchange Act of 1934, as amended, including those regarding Dyadic International’s expectations,

trial and interest in our protein production platforms, our research projects and third-party collaborations, as well as the availability

of necessary funding. Forward-looking statements generally can be identified by use of the words “expect,” “should,”

intend,” anticipate,” “will,” “project,” “may,” “might,” “potential,”

(v) the results of nonclinical studies and clinical trials; (vi) our capital needs; (vii) changes in global economic and financial

conditions; (viii) our reliance on information technology; (ix) our dependence on third parties; (x) government regulations

standards of the Nasdaq. For a more complete description of the risks that could cause our actual results to differ from our current

expectations, please see the section entitled “Risk Factors” in Dyadic’s annual reports on Form 10-K and quarterly

reports on Form 10-Q filed with the Securities and Exchange Commission (the “SEC”), as such factors may be updated from time

to time in Dyadic’s periodic filings with the SEC, which are accessible on the SEC’s website and at www.dyadic.com. All forward-looking

statements speak only as of the date made, and except as required by applicable law, Dyadic assumes no obligation to publicly update

any such forward-looking statements for any reason after the date of this press release to conform these statements to actual results

or to changes in our expectations.
