open-market sale financial

"Transaction action is labeled as an open-market sale of Common Stock."

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.

Common Stock financial

"Each reported transaction involves Ainos, Inc. Common Stock."

Common stock represents ownership shares in a company, giving investors a stake in its success and a say in important decisions through voting rights. It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth. For investors, holding common stock means sharing in the company’s profits and risks.

income tax obligations financial

"A footnote states shares were sold to cover income tax obligations."

transaction code "S" financial

"Each trade carries transaction code "S" for a sale."
