Industry Context

This filing reflects a routine executive compensation event, common across publicly traded companies, where Restricted Stock Units (RSUs) vest and stock options are granted as part of an annual incentive program. Such compensation structures are designed to align executive interests with long-term shareholder value creation and retain key talent within the biotechnology or enzyme technology sector, where Dyadic International operates.

Comparison to Industry Standards

• The use of RSUs and stock options as components of executive compensation is a standard practice across various industries, including biotechnology and specialty chemicals, aligning with typical incentive structures seen in companies like Novozymes or Codexis.
• The vesting schedule for stock options, typically over several years and contingent on continued service, is a common mechanism to promote long-term executive retention and performance, comparable to practices at peer companies.
• The grant of RSUs in lieu of a cash bonus for performance is also a recognized method to conserve cash while still rewarding executives and increasing their equity stake, a strategy often employed by growth-oriented companies.

Stakeholder Impact

• Shareholders: Increased alignment of the Chief Financial Officer's interests with shareholders due to higher equity ownership.
• Employees: The compensation structure reflects standard practices for key employees, potentially influencing morale and retention.

Next Steps

• The stock options granted on January 2, 2026, will begin to vest in four equal installments starting on January 2, 2027, subject to the CFO's continued service to the Issuer.
