restricted stock units financial

"Represents restricted stock units awarded under the Maravai LifeSciences Holdings, Inc. 2020 Omnibus Incentive Plan"

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

2020 Omnibus Incentive Plan financial

"awarded under the Maravai LifeSciences Holdings, Inc. 2020 Omnibus Incentive Plan on May 26, 2026"

pecuniary interest financial

"The Reporting Person disclaims any pecuniary interest in the securities"

beneficial owner financial

"this report shall not be deemed an admission that the Reporting Person is the beneficial owner of the securities"

A beneficial owner is the person who ultimately owns or controls a financial asset or property, even if their name isn't directly on official documents. Think of it like someone who secretly holds the keys to a safe deposit box—others may appear to have access, but the true owner is the one who benefits from what's inside. Identifying beneficial owners helps ensure transparency and prevent illegal activities like money laundering or fraud.

GTCR-affiliated entity financial

"holds these securities of the Issuer for the benefit of a GTCR-affiliated entity"
