10b5-1 plan date June 13, 2025 Plan governing the reported stock sales
Rule 10b5-1 plan financial
"Shares sold pursuant to a 10b5-1 plan dated June 13, 2025."
A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.
weighted-average sales price financial
"Price reported is a weighted-average sales price. The shares were sold at prices ranging..."
Class B Common Stock financial
"Each share of Class B Common Stock is convertible at any time at the option of the Reporting Person..."
A class B common stock is one of multiple types of a company’s ordinary shares that carries specific rights—often different voting power or dividend priority—compared with other classes. For investors it matters because those differences affect how much influence you have over company decisions, the income you might receive, and how freely the shares trade; think of it like owning a car with different keys: some keys let you start the engine and open the trunk, others only unlock the door.
derivative conversion financial
"transaction_action": "derivative conversion""
revocable trust financial
"Shares are held by the Alexis Le-Quoc Revocable Trust."
A revocable trust is a legal arrangement where the person who creates it keeps control and can change or cancel the trust at any time, while naming who will manage and receive the assets later. Think of it like a flexible folder for your investments and property that can be relabeled or reworked as circumstances change; it matters to investors because it determines how ownership is recorded, how easily assets transfer on incapacity or death, and whether holdings bypass public probate proceedings.
