Key Terms

3 terms

restricted common stock financial

"This amount includes 14,667 shares of restricted common stock subject to vesting"

Restricted common stock is company shares that carry limits on selling or transferring for a set period or until certain conditions are met, like time-based vesting or regulatory clearance. Think of them as shares in a locked box that gradually open; they can become freely tradable later but initially reduce the number of shares available on the market. Investors watch restricted stock because its eventual release can change a company’s share supply, affect stock price, and influence control and dilution.

weighted average sale price financial

"Reflects the weighted average sale price. The highest price at which shares were sold"

long term incentive plan financial

"under the Issuer's Riley Exploration Permian, Inc. Second Amended and Restated 2021 Long Term Incentive Plan"

A long term incentive plan is a company program that awards executives and key employees bonuses—often in stock, options, or cash—only if the business meets multi-year performance goals. It links management pay to company results—like tying a coach’s bonus to a team’s multi-season record—so investors monitor it for how leaders are motivated, potential share dilution, and signals about the company’s long-term priorities.
