restricted stock units (RSUs) financial

"Represents the award of restricted stock units (RSUs) under the Casella Waste Systems, Inc. Amended and Restated 2016 Incentive Plan."

Restricted stock units (RSUs) are a type of company promise to give employees shares of stock in the future, usually after certain conditions like working for a set time. They are like a gift promised today that you receive later, which can become valuable if the company's stock price goes up. RSUs matter because they are a way companies reward employees and can be a significant part of compensation.

Amended and Restated 2016 Incentive Plan financial

"Represents the award of restricted stock units (RSUs) under the Casella Waste Systems, Inc. Amended and Restated 2016 Incentive Plan."

Class A Common Stock financial

"Each RSU represents a contingent right to receive one share of Casella's Class A Common Stock."

Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
