Key Terms

3 terms

restricted stock financial

"shares or units of restricted stock"

Shares granted to an individual that carry limits on transfer or sale until certain conditions are met, such as staying with the company for a set time or hitting performance targets. Think of them as a locked gift that gradually opens; for investors they matter because they affect how many shares may enter the market later, signal management incentives and potential dilution, and reveal confidence in future company performance.

PSUs financial

"shares of Common Stock underlying PSUs"

PSUs are company shares promised to employees or executives that only become actual stock if the business hits specific performance targets over a set period. For investors, PSUs matter because they link pay to measurable outcomes — similar to a conditional bonus that converts into ownership — which can influence management decisions, dilution of shares, and signals about confidence in future results.

Employee Stock Purchase Plan financial

"shares of Common Stock purchased under the Issuer's 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.
