Restricted Stock Unit financial

"Each Restricted Stock Unit represents a contingent right to receive one share"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

Performance Shares financial

"Performance Shares vest in an amount ranging from 0-200% to the extent such Performance Shares are earned"

Performance shares are a type of company stock given to executives or employees that only become theirs if the company meets specific goals, like hitting certain profits or growth targets. They motivate leaders to work toward the company’s success, because their additional shares depend on achieving these results.

EBITDA margin financial

"Performance Shares are earned based on NWPX's total EBITDA margin over the measurement period"

EBITDA margin is the share of each dollar of sales that a company keeps as operating cash profit before interest, taxes, and accounting for equipment wear and long-term investments. Think of it like the cash a store has left from every sale after paying day-to-day running costs but before paying rent, loan interest or replacing old machinery. Investors use it to compare core profitability and operational efficiency across companies by removing financing and accounting differences.
