Key Terms

4 terms

Pre-Funded Warrants financial

"Reflects Pre-Funded Warrants issued as payment of interest pursuant to a Convertible Note"

Pre-funded warrants are financial instruments that give investors the right to purchase a company's stock at a set price, but with most or all of the purchase price paid upfront. They function like a coupon or gift card for stock, allowing investors to buy shares later at a fixed price, which can be beneficial if they want to avoid future price increases. This makes them important for investors seeking flexibility and certainty in their investment plans.

Convertible Note financial

"payment of interest pursuant to a Convertible Note of the Issuer dated May 25, 2025"

A convertible note is a type of loan that a company gets from investors, which can later be turned into company shares instead of being paid back in cash. It matters because it helps startups raise money quickly without setting a fixed value for the company right away, making it easier to grow and attract investors.

beneficial owner financial

"RSLGH is the direct beneficial owner of the Convertible Note and the Pre-Funded Warrants"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

ten percent owner regulatory

"RSLGH, LLC and Green Thumb Industries Inc. are each listed as a ten percent owner"
