reverse stock split financial
"On May 30, 2025, the Issuer effected a 1-for-20 reverse stock split of its common stock."
A reverse stock split is when a company reduces the number of its shares outstanding, making each share more valuable. For example, if you own 100 shares worth $1 each, a 1-for-10 reverse split would turn your 100 shares into 10 shares worth $10 each. Companies often do this to boost their stock price and appear more stable to investors.
Option (right to buy) financial
"Option (right to buy) transaction covering 9,250.0000 derivative shares."
exercise price financial
"conversion_or_exercise_price: 13.2200 per share on the granted options."
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.
grant, award, or other acquisition financial
"transaction_code_description: Grant, award, or other acquisition."
vesting financial
"The option shares shall vest on the earlier of the next annual meeting or the first anniversary of June 10, 2026."
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.
