2019 Omnibus Incentive Plan financial

"granted to the reporting person pursuant to the Issuer's 2019 Omnibus Incentive Plan"

annualized return on equity financial

"earned upon the Issuer's achievement of a specified annualized return on equity"

Annualized return on equity measures how much profit a company generates each year for every dollar investors have left in the business after liabilities are subtracted. Think of shareholder equity as seeds you plant and annualized ROE as the yearly harvest rate—higher values mean the company is generally better at turning investor money into profit, and annualizing lets investors compare performance on a common yearly basis.

vest financial

"have vested on June 30, 2026 but have not yet been issued"

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.

notionally divided financial

"after which, such earned shares are notionally divided into a number"
