Class A Common Stock financial

"241 shares of Class A Common Stock on September 4, 2026 at $1.03"

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.

indirect ownership financial

"He indirectly holds 136,151 shares through The Landesberg Living Trust"

Rule 10b5-1 trading plan regulatory

"No Rule 10b5-1 trading plan is reported for this transaction"

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.

co-trustees other

"for which he and his spouse serve as co-trustees"
