4 terms

restricted stock units ("RSUs") financial

"Grant of restricted stock units ("RSUs") pursuant to the Ingevity Corporation 2025 Omnibus 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.

Omnibus Incentive Plan financial

"pursuant to the Ingevity Corporation 2025 Omnibus Incentive Plan, which will vest in three equal installments"

An omnibus incentive plan is a single, flexible program a company uses to give employees and executives different types of pay tied to performance — for example stock options, restricted shares, cash bonuses and other awards — all governed by one set of rules. It matters to investors because it determines how many new shares may be created, how leaders are motivated and how much the company will spend on compensation over time; think of it as a master toolbox that affects both costs and the total share supply.

Employee Stock Purchase Plan financial

"purchased pursuant to the Amended and Restated 2017 Ingevity Corporation Employee Stock Purchase Plan, as amended ("ESPP")"

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.

vesting financial

"which will vest in three equal installments on May 1, 2027, 2028, and 2029"

Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
