Transaction code P Indicates open-market or private <b>purchase</b> of non-derivative securities
Class A Common Stock financial
"purchased a total of shares of <b>Class A common stock</b> in open-market"
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.
weighted average purchase price financial
"executed in multiple trades ranging from $1.16 to $1.30; the price reported reflects the <b>weighted average purchase price</b>"
The weighted average purchase price is the average cost per share you paid across multiple buys, calculated so larger purchases count more than smaller ones. Imagine buying apples at different prices: the overall price you effectively paid depends on how many apples you bought at each price. Investors use it to measure true cost basis, calculate gains or losses, decide when to sell, and manage taxes and portfolio performance.
Revocable Trust financial
"Represents shares purchased by The Eric S. Grossberg <b>Revocable Trust</b>, for which Mr. Grossberg serves as Trustee"
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.
LLC Interests financial
"in addition to the <b>LLC Interests</b> and associated shares of Class C common stock held by Just Rocks, Inc."
Rule 10b5-1 regulatory
"These purchases are not marked as made under a <b>Rule 10b5-1</b> trading plan"
Rule 10b5-1 is a regulation that allows company insiders to buy or sell their shares at predetermined times, even if they have access to non-public information. It acts like setting a schedule in advance for transactions, helping prevent accusations of unfair trading. This rule provides a way for insiders to plan trades transparently, giving investors confidence that these transactions are not based on hidden information.
