Equity Shares financial

"The Subordinate Voting Shares, Restricted Voting Shares, and/or Limited Voting Shares of Glass House Brands Inc. ("GHBI") (collectively, the "Equity Shares")."

Equity shares are units of ownership in a company that give the holder a claim on a portion of its assets and profits, like owning a slice of a business. They matter to investors because their value can rise or fall with the company’s performance and market sentiment, may provide periodic income through dividends, and often carry voting rights that influence how the business is run.

weighted average sale price financial

"Represents the Equity Shares sold at a weighted average sale price of $10.08 per share."

open-market sale financial

"transaction_action": "open-market sale""

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.
