open-market sale financial

"transaction_action: "open-market sale" for both Common Shares transactions"

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.

weighted average sale price financial

"The sale price reported above represents the weighted average sale price for the reported transaction."

Common Shares financial

"The Common Shares sold by the Reporting Person and reported herein were sold at a range of between $77.745 and $78.50 per share."

Common shares are the basic units of ownership in a company that give holders a claim on profits and a right to vote on key matters, like electing the board. Think of them as membership cards in a club: they let you share in successes and losses, but in a bankruptcy or liquidation they are paid after creditors and preferred shareholders, so their value can swing more and matters for assessing risk and potential return.
