Key Terms

4 terms

nasdaq listing rule 5635(c)(4) regulatory

"as an inducement material to Dr. Aggarwal becoming an employee of Cardiff Oncology in accordance with Nasdaq Listing Rule 5635(c)(4)."

NASDAQ Listing Rule 5635(c)(4) is a rule that requires a company to get approval from its shareholders before selling a large amount of its shares, usually over 20%. This helps protect investors by making sure the company doesn't flood the market with new shares without their say, which could lower the stock's value.

non-qualified stock options financial

"approved the grant of non-qualified stock options to purchase 400,000 shares of Cardiff Oncology common stock"

Non-qualified stock options are a type of employee benefit that gives individuals the right to buy company shares at a set price, usually lower than the market value, within a certain period. Unlike other options that may have special tax advantages, these options are taxed as income when exercised, which can affect how much money the employee or investor ultimately gains. They are important because they can influence company compensation strategies and impact the financial outcomes for employees and investors.

exercise price financial

"has an exercise price of $1.72 per share, the closing price on the grant date."

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.

equity incentive plan financial

"outside of the Cardiff Oncology 2021 Omnibus Equity Incentive Plan."

An equity incentive plan is a program that gives employees, executives or directors the right to receive company stock or options to buy stock as part of their pay. Think of it as offering slices of future company profit to motivate people to boost long‑term performance; for investors it matters because it can align employee goals with shareholder value but also increases the number of shares outstanding, which can dilute existing ownership.
