5 terms

restricted stock unit ("RSU") financial

"Represents a restricted stock unit ("RSU") grant pursuant to the Issuer's non-employee director compensation policy"

non-employee director compensation policy financial

"RSU grant pursuant to the Issuer's non-employee director compensation policy (the "Policy")"

reverse stock split financial

"Effective October 17, 2025, the Issuer effected a 1-for-20 reverse stock split"

A reverse stock split reduces a company's number of outstanding shares while raising the price per share proportionally, so the total value of each investor's holding is unchanged; a 1-for-10 split turns 100 shares worth $1 each into 10 shares worth $10 each. Companies often do this to regain compliance with an exchange's minimum price rule or to attract investors who avoid very low-priced stocks.

stock option grant financial

"Represents a stock option grant pursuant to the Policy"

exercise price financial

"conversion_or_exercise_price": "5.7100""

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.
