3 terms

Private Warrants financial

"up to 75,000 Private Warrants originally issued in a private placement"

A private warrant is a contract sold directly to selected investors that gives the holder the right to buy a company’s stock at a fixed price in the future. Think of it as a coupon for shares that isn’t offered on public markets: it can provide the company with future cash if exercised but can also dilute existing shareholders by increasing the number of outstanding shares, so investors watch exercise price, expiration and transfer restrictions closely.

Selling Securityholders regulatory

"offer and sale from time to time by the selling securityholders named in the Prospectus"

Selling securityholders are existing owners of a company's stocks or other tradable claims who are offering some or all of their holdings for sale in a public offering or secondary transaction. Investors watch these sellers because large or insider sales can increase the number of shares available, put downward pressure on price, and signal insiders’ views about future prospects—much like many people selling tickets at once can change the market for an event.

Registration Rights regulatory

"registrable pursuant to that certain Amended and Restated Registration Rights Agreement"

Registration rights are contractual promises that let investors require a company to file paperwork with securities regulators so those investors can sell their shares to the public. They matter because they create a path to liquidity and an exit plan—without them, investors may be stuck holding shares for a long time. Think of them like a reserved ticket that guarantees access to a public marketplace when the holder is ready to sell.
