performance-based restricted stock units financial

"Represents shares of Common Stock received upon the vesting of a portion of the performance-based restricted stock units ("PSUs")..."

Performance-based restricted stock units are a type of employee equity award that converts into company shares only if predefined financial or operational targets are met over a set period. Think of it like a bonus check that becomes stock only when specific goals are hit; it ties pay to results, aligning managers’ incentives with shareholders. Investors care because these awards affect future share count, executive incentives, and signal how management’s success will be measured and rewarded.

PSUs financial

"Each PSU represents the contingent right to receive one share of Common Stock of the Issuer."

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.

long-term incentive bonus plan financial

"awarded to the Reporting Person on March 24, 2023 under the Issuer's long-term incentive bonus plan and 2016 Equity Incentive Plan..."

2016 Equity Incentive Plan financial

"under the Issuer's long-term incentive bonus plan and 2016 Equity Incentive Plan, which vested based on the Issuer's satisfaction..."

Restricted Stock Units financial

"vesting of PSUs and certain Restricted Stock Units previously granted to the Reporting Person."

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.

tax withholding obligations financial

"shares of Common Stock withheld by the Issuer to satisfy tax withholding obligations for the Reporting Person..."
