restricted stock units ("RSUs") financial

"Reflects restricted stock units ("RSUs") granted to the reporting person under the ProFrac Holding Corp. 2022 Long Term Incentive Plan."

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

grant date fair value financial

"The RSUs were granted with a total grant date fair value of $150,000, as approved by the Compensation Committee"

The grant date fair value is the estimated dollar worth of a stock-based award (such as stock options or restricted shares) at the exact moment it is given to an employee or contractor. Investors care because companies use that value to record compensation expenses and to show how much potential ownership and earnings dilution those awards could create—think of it as the price tag placed on a gift card when it is handed over so the company can report the cost now.
