Rule 10b5-1 trading plan regulatory
"pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person"
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 price financial
"The price reported is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
Class A Common Stock financial
"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.
limited liability company financial
"controls a limited liability company that is a member of 346 Long LLC"
A limited liability company (LLC) is a business structure that separates the owners’ personal assets from the company’s debts and legal obligations, like a protective shield that keeps personal savings and property distinct from business risk. For investors, that protection reduces personal financial exposure and often brings flexible rules for profit sharing and taxes, but it can also affect how easily interests are bought or sold and how decisions are made.
