Performance stock units financial
"Performance stock units ("PSUs") convert into common stock on a one-for-one basis."
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.
restricted stock units financial
"Includes (i) 15,625 unvested restricted stock units ("RSUs") of the 83,333 RSUs granted..."
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.
Rule 10b5-1 plan financial
"Transaction effected pursuant to a Rule 10b5-1 plan adopted by the Reporting Person..."
A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.
Employee Stock Purchase Plan financial
"2,650 shares acquired under the Liquidia Corporation 2020 Employee Stock Purchase Plan."
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
vest ratably on a quarterly basis financial
"the remaining PSUs shall vest ratably on a quarterly basis over three years thereafter."
