Warrants financial
"holders of its outstanding warrants, each exercisable for one share"
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.
Expiration Date financial
"will expire on September 16, 2026, at 5:00 p.m., New York City time (the “Expiration Date”)"
The expiration date is the deadline after which a financial contract, such as an option or a futures agreement, is no longer valid or can be exercised. It matters to investors because it determines the timeframe during which they can take action or benefit from the contract, similar to how a coupon or a food item has a limited period of usefulness. Once the expiration date passes, the contract loses its value or ability to be used.
Warrant Agreement financial
"in accordance with the Warrant Agreement, dated as of October 27, 2020"
A warrant agreement is the legal document that lays out the rules for stock warrants — special certificates that let their holder buy company shares at a set price within a certain time. It explains how and when warrants can be exercised, transferred, changed, or canceled, and what happens to them if the company raises money or is sold; investors care because these terms affect potential future ownership, dilution of shares, and the real value of the warrants.
Section 802.01D regulatory
"halted by the New York Stock Exchange on September 1, 2026 pursuant to Section 802.01D"
New York Stock Exchange Listed Company Manual regulatory
"pursuant to Section 802.01D of the NYSE Listed Company Manual"
A listed company manual is the rulebook a stock exchange uses to set the standards and requirements companies must meet to join and remain on the exchange. Think of it as a membership handbook that covers what companies must disclose, how they should govern themselves, and what practices they must follow; for investors this matters because it creates baseline transparency and accountability, helping assess risk and trustworthiness and protecting the value of their holdings.
