Rule 10b5-1 trading plan regulatory

"The sales reported ... were effected pursuant to a Rule 10b5-1 trading plan adopted on June 2, 2025."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

weighted average sale price financial

"The reported price in Column 4 is a weighted average sale price."

open market or private transaction financial

"Transaction code S is described as a sale in open market or private transaction."

Class A Common Stock financial

"Security title for the reported transactions is Class A Common Stock."

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
