"These shares are issuable on vesting of restricted stock units granted under the Company's 2012 Equity Incentive Plan"
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.
