Restricted stock units financial
"Restricted stock units that (1) vest in full on the earlier of the first anniversary"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
reverse stock split financial
"the Issuer effected a 1-for-15 reverse stock split (the "Reverse Stock Split")"
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.
