Common Stock Purchase Warrant financial
"Security acquired was a Common Stock Purchase Warrant for 687,285 underlying shares."
A common stock purchase warrant is a tradable certificate that gives its holder the right to buy a company’s common shares at a fixed price for a set period. Think of it as a coupon that lets you buy stock later at today’s agreed price; it can amplify gains if the share price rises but also can increase the total number of shares outstanding, which may reduce existing owners’ percentage of the company. Investors watch warrants because they offer leveraged upside and can affect future share value and ownership.
Initial Exercise Date financial
"Exercisable beginning on the later of six months after issuance or the Authorized Share Increase Date (the Initial Exercise Date)."
Authorized Share Increase Date financial
"Authorized Share Increase Date means the date an amendment increasing authorized common shares is filed and accepted."
certificate of incorporation regulatory
"An amendment to the issuer's certificate of incorporation must increase authorized shares for full warrant exercise."
A certificate of incorporation is an official government document that creates a corporation and records key facts such as its legal name, basic governance structure, and stock authorization—think of it as a company's birth certificate plus its basic rulebook. Investors care because it establishes the company’s legal existence, limits owners’ personal liability, and sets the framework for issuing shares and enforcing shareholder rights, which affects ownership, control and the company’s ability to raise capital.
