Rhea-AI Filing Summary

Atmus Filtration Technologies reported that SVP and Chief Supply Chain Officer Kevin N. Carpenter received an equity award in the form of 28,509 shares of common stock. These are restricted stock units granted at no cash cost to him as part of Atmus' long-term incentive programs.

The award includes RSUs under the 2022 Omnibus Incentive Plan tied to the annual long-term incentive compensation program, which will vest in three equal tranches beginning on March 1, 2027, and a separate one-time long-term incentive award vesting in three equal tranches beginning on May 18, 2027. Each vested RSU will convert into one share of Atmus common stock, so Carpenter will own the shares only as they vest over time.

restricted stock units ("RSUs") financial

"Represents restricted stock units ("RSUs") granted under the Atmus Filtration Technologies Inc."

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.
