restricted stock units ("RSUs") financial

"Reflects restricted stock units ("RSUs") granted under the Magnolia Oil & Gas Corporation 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.

Long Term Incentive Plan financial

"RSUs granted under the Magnolia Oil & Gas Corporation Long Term Incentive Plan (the "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.

vest financial

"The RSUs will vest on the earlier of (a) the day preceding the next annual meeting"

A vest is the process by which an employee earns the right to receive certain benefits or ownership interests, such as stock or retirement funds, over time. It’s similar to earning a reward gradually, ensuring that the benefit becomes fully yours only after a set period or meeting specific conditions. This makes it important for investors because it determines when they can actually claim or use those benefits.

annual meeting of stockholders financial

"the day preceding the next annual meeting of stockholders of the Company at which directors are elected"
