Ainos (NASDAQ: AIMD) holder TCNT shifts voting control over 13.62% stake

Rhea-AI Filing Summary

Taiwan Carbon Nano Technology Corporation (TCNT) updated its ownership and voting arrangements in Ainos, Inc. TCNT now beneficially owns 989,925 shares of Ainos common stock, representing 13.62% of the outstanding shares, after recent sales including 46,000 shares sold on January 28, 2026.

The filing explains that TCNT originally received Ainos shares in August 2024 under a license agreement, in exchange for granting an exclusive, irrevocable, and perpetual license to certain gas sensor and medical device patents. Ainos later implemented a one‑for‑five reverse stock split and TCNT has been gradually selling shares.

On January 1, 2026, TCNT entered into a voting agreement with Ainos Inc., a Cayman Islands corporation, covering the Ainos shares held by TCNT. Under this agreement, TCNT agreed to vote all of its Ainos voting stock as determined by Ainos KY in its sole discretion, effectively transferring voting control while retaining economic ownership.

Insights

Corporate governance and ownership structure analyst

Voting control over a 13.62% stake shifts under a new agreement.

TCNT now reports beneficial ownership of 989,925 Ainos shares, stated as 13.62% of the common stock. These shares stem from a patent license deal where Ainos issued stock in exchange for exclusive rights to gas sensor and medical device patents.

The filing notes that TCNT has been selling shares over time, including 46,000 shares on January 28, 2026. Despite these sales, TCNT still directly holds 989,925 shares, so the economic stake remains significant relative to the company’s disclosed outstanding share base.

A key change is governance-related: as of January 1, 2026, TCNT agreed via a voting agreement to vote all its Ainos stock as directed by Ainos KY, in Ainos KY’s sole discretion. This concentrates voting power for a sizeable block without transferring economic ownership, which may affect how shareholder decisions are influenced until the agreement’s first anniversary and any automatic one‑year extensions.
