4 terms

non-qualified stock options financial

"the company granted non-qualified stock options to purchase 50,050 shares"

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.

inducement stock incentive plan financial

"under Xilio Therapeutics’ 2022 Inducement Stock Incentive Plan"

An inducement stock incentive plan is a program that gives newly hired employees or executives shares or stock-based awards as a reward for joining a company and to encourage them to stay and perform. For investors, it matters because these grants can dilute existing shareholders, increase reported compensation costs, and signal how a company is investing in talent—similar to a signing bonus mixed with a stake in the business.

exercise price financial

"The stock options have an exercise price of $0.5283 per share"

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.

nasdaq listing rule 5635(c)(4) regulatory

"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.
