TCNT controls the company via its majority interest in Ainos Inc., a Cayman Islands corporation (“Ainos KY”) and its direct ownership in the Company. Ainos KY is a shareholder of the Company and holds majority control of the voting power of the Company through certain previously disclosed voting agreements.

On October 15, 2025, the Company and TCNT entered into the fourth addendum to the Product Development Agreement (the “Fourth Addendum Agreement”) to amend the fee for the exclusive use of patents of $50,000 per month (plus 5% sales tax) for a two-year period starting from October 16, 2025, instead of one year starting from October 16, 2024.
