Key Terms

warrants, private placement, Series A Rights, Series B Rights

4 terms

warrants financial

"the warrants issued in its April 2021 private placement expired in accordance"

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.

View in glossary

private placement financial

"the warrants issued in its April 2021 private placement expired in accordance"

A private placement is a sale of securities directly to a selected group of investors, typically institutions or accredited investors, instead of through a public offering. It lets a company raise money faster and with fewer regulatory steps; for existing shareholders it matters because the newly issued shares, often sold at a discount, increase the share count and can dilute their ownership.

Series A Rights financial

"The Company’s common stock, Series A Rights, and Series B Rights continue to trade"

Series A rights are the specific protections and privileges attached to the first round of preferred shares sold to early investors, such as priority on company payouts, special voting influence, and the ability to keep their ownership percentage in later financing rounds. Think of them like a VIP ticket that gives holders safer exit priority and stronger say in company decisions, which matters to investors because those rights reduce risk and preserve value.

Series B Rights financial

"The Company’s common stock, Series A Rights, and Series B Rights continue to trade"

Series B rights are the specific protections and privileges attached to shares sold in a company’s Series B financing round, such as priority for getting paid before common shareholders, guaranteed dividend or payout terms, anti-dilution protections, and sometimes board seats or voting powers. Investors care because these rights determine how much money and influence Series B holders will get compared with others—like having a reserved place in line and a bigger slice of the pie if the company is sold or goes public.
