selling stockholders financial

"resale by the selling stockholders listed in the Prospectus"

Selling stockholders are existing owners of a company's shares who are offering some or all of their holdings for sale, often as part of a public offering or secondary transaction. For investors this matters because such sales increase the number of shares available to buy, can signal how confident current owners are about future prospects, and may put short-term pressure on the stock price similar to more tickets being released for a popular event.

Warrants financial

"shares of Common Stock underlying warrants (“Warrants”)"

Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.

Broker Non-Vote financial

"Broker Non-Vote | 71,479,395"

A broker non-vote happens when a brokerage firm holds shares in street name for a client but does not cast a ballot on a particular shareholder item because the broker lacks discretionary authority to vote that matter. Think of it like a person who owns a ticket but the ticket-holder refuses to vote on some issues; the share counts for ownership but not for that vote, which can affect whether proposals reach the required number of votes or a quorum.

record date regulatory

"record date for shareholders entitled to notice of, and to vote at, the Annual Meeting"

The record date is the specific day when a company determines which shareholders are eligible to receive a dividend or participate in an upcoming vote. It’s like a cutoff date; if you own the stock on that day, you get the benefits or voting rights. This date matters because it decides who qualifies for certain company benefits.

independent registered public accounting firm regulatory

"Frazier & Deeter, LLC as the Company’s independent registered public accounting firm"

An independent registered public accounting firm is an outside accounting company officially registered with the government regulator to examine and report on a public company's financial records and controls. Investors treat its reports like an impartial inspector’s certificate — they add credibility to financial statements, help spot errors or misleading claims, and reduce the risk that shareholders are relying on unchecked or biased numbers.
