Rule 10b5-1(c) plan financial

"Adoption date of referenced 10b5-1(c) plan is: 05/05/2026"

Restricted Stock Units financial

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

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.

Performance Shares financial

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

weighted average sale price financial

"The price reported reflects the weighted average sale price."

EBITDA margin financial

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