Subscription Rights financial
"Represents the conversion of a subscription right issued by the Issuer as part of a rights offering"
Subscription rights are short-term privileges given to existing shareholders to buy additional new shares before the general public, typically at a set price and in proportion to their current holdings. Think of it as getting a coupon for first dibs on extra slices of a pizza so your share of the pie doesn’t shrink; exercising them can be a cheaper way to maintain your ownership and voting power, while ignoring them can reduce your stake and potential future earnings.
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.
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
"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.
redeemed financial
"Warrants became exercisable immediately after the Rights Offering closed and expire 10 years later, unless exercised or redeemed earlier"
