What Happened

• Director Chiang Yao-Chung purchased 2,000 shares of Ainos, Inc. (AIMD) in an open-market transaction on May 27, 2026, at $2.00 per share, for a total cost of $4,000. This was a straightforward purchase (investors often view purchases as more informative than routine sales).

Key Details

• Transaction date and price: May 27, 2026 — 2,000 shares @ $2.00/share (total $4,000).
• Transaction type/code: Open market purchase (P).
• Shares owned after transaction: The filing does not state an updated total; it notes the Reporting Person directly owns 90,880 shares as previously disclosed (in addition to any indirectly held shares).
• Footnotes: F1 — confirms the Reporting Person directly owns 90,880 shares as previously disclosed.
• Filing timeliness: The Form 4 was filed May 29, 2026 for the May 27 transaction (filed within the normal 2-business-day window).

Context

• This was a cash open-market purchase, not an option exercise, gift, or withholding. The amount ($4,000) is relatively small, so while it is a buy signal, it’s modest in dollar terms. As a director, Chiang’s trades are reported under Section 16; the filing shows ownership disclosure but does not indicate 10% beneficial ownership.
