5 terms

10b5-1 plan regulatory

"Shares sold pursuant to a 10b5-1 plan dated December 15, 2025."

A 10b5-1 plan is a pre-arranged strategy that allows company insiders to buy or sell their shares at predetermined times and prices, even while they are aware of confidential information. It acts like a scheduled appointment for trading, helping ensure transactions happen transparently and legally, which can reassure investors that trades are not based on insider knowledge.

Class B Common Stock financial

"Each share of Class B Common Stock is convertible into one share of Class A."

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.

weighted-average sales price financial

"Price reported is a weighted-average sales price for shares sold in multiple trades."

Stock Option (Right to Buy) financial

"Derivative security described as a Stock Option (Right to Buy) with an exercise price and expiration."
