restricted AB Holding Units financial

"granted 4,397 restricted AB Holding Units to the Reporting Person"

Independent Director financial

"each Independent Director recused himself or herself from approving this grant"

An independent director is a member of a company's board of directors who is not involved in the company's day-to-day operations and has no significant relationships with the company that could influence their judgment. Their role is to provide unbiased oversight and ensure the company is managed in the best interests of all shareholders. This helps build trust and confidence among investors by promoting transparency and accountability.

vesting financial

"The AB Holding Units will vest and be delivered in equal 33.33% increments"

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.

closing price financial

"Closing price of an AB Holding Unit (NYSE: AB) on the grant date"
