Restricted Stock Unit financial

"Each RSU represents a contingent right to receive one share of Ameresco, Inc. Class A Common Stock"

A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.

non-employee director compensation plan financial

"Annual grant pursuant to Ameresco, Inc.'s non-employee director compensation plan."

Class A Common Stock financial

"Each RSU represents a contingent right to receive one share of Ameresco, Inc. 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.
