cashless basis financial
"paid the exercise price on a cashless basis, resulting in the Issuer withholding"
An agreement executed on a cashless basis lets a holder convert or exercise a security (like options, warrants, or conversion rights) without paying money upfront; instead the holder receives a smaller number of shares equal in value to what the cash would have purchased. Think of trading a coupon for fewer slices of a cake rather than handing over cash for the full slice. For investors, it affects how much ownership and dilution occur and avoids immediate cash outlays.
stock option financial
"The Reporting Person exercised a stock option to purchase 63,788 shares"
A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
