equity interests financial

"Equity interests in the Issuer were purchased pre-IPO."

Equity interests are an ownership stake in a company—usually represented by shares or membership units—that give the holder a claim on the business’s profits, assets and sometimes voting power. Think of it as owning one or more slices of a company’s pie: the bigger your slice, the larger your share of dividends, capital gains and influence, and the more you are affected by dilution or company losses. Investors use equity interests to measure value, control and potential returns.

Common Stock financial

It is the most common type of stock traded on markets and can provide income through dividends, as well as potential for value growth.
