Rights Offering financial
"issued by the issuer as part of a rights offering that closed on July 21, 2026"
A rights offering is a way for a company to raise additional money by giving existing shareholders the opportunity to buy more shares at a discounted price before they are offered to the public. It’s similar to a special sale where current owners get the first chance to buy extra items at a lower cost, allowing them to increase their investment if they choose. This process matters to investors because it can affect the value of their holdings and their ability to buy new shares at favorable terms.
subscription right financial
"Represents the conversion of a subscription right issued by the issuer"
A subscription right is a short‑term entitlement given to existing shareholders that lets them buy additional shares at a set price before the shares are offered to the public. Like a limited-time coupon to buy more of a product, it matters to investors because exercising the right can prevent ownership from being diluted and may offer a discounted chance to increase holdings, while selling the right can provide immediate cash if they don’t want more shares.
warrant financial
"0.4388 of a warrant exercisable to acquire a share of common stock"
A warrant is a time-limited financial contract that gives its holder the right to buy a company's shares at a set price before a specified date, like a coupon that lets you purchase stock at a fixed discount for a limited time. It matters to investors because warrants offer leveraged exposure to a stock’s upside and can dilute existing shareholders if exercised, so they affect potential gains and the company’s outstanding share count.
exercise price financial
"a warrant exercisable to acquire a share of common stock at an exercise price of $5.48 per share"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
