nasdaq listing rule 5635(c)(4) regulatory

"granted inducement to a new non-executive employee under the terms of the 2022 Employment Inducement Award Plan. The equity award was approved on March 12, 2026, 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.

exercise price financial

"The option carries a ten-year term and an exercise price per share equal to $5.66, which was the closing price"

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.

vesting financial

"and vests over 4 years, with 25% of the shares underlying the options vesting on the first anniversary"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
