Insights

Equity ownership & governance analyst

Ainos clarifies a 6.76% stake and broad voting control via agreements.

The amendment shows Ainos Inc. (Cayman) beneficially owns 491,263 common shares, or 6.76% of Ainos, Inc., calculated against a detailed share count that includes prior issuances, stock awards, ATM sales, and shares issued to ScentAI Inc.

Importantly, Ainos holds sole voting power over 3,536,073 shares through direct holdings and two voting agreements with insiders and ASE Test, Inc. These arrangements give it significant influence over shareholder votes without full economic ownership of all such shares.

The filing notes a sale of 46,000 shares by Taiwan Carbon Nano Technology Corporation, which remain covered by the 2026 Voting Agreement. The investor states an investment purpose but may consider future proposals or transactions, so later governance or transaction updates would likely appear in subsequent filings.
