Restricted Stock Units financial

"Each restricted stock unit ("RSU") is granted under the Sphere Entertainment Co. 2020 Stock Plan for Non-Employee Directors"

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 Stock Plan for Non-Employee Directors financial

"granted under the Sphere Entertainment Co. 2020 Stock Plan for Non-Employee Directors, as amended"

Class A Common Stock financial

"represents a right to receive one share of Class A Common Stock or the cash equivalent thereof"

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.

separation from service financial

"will be settled in stock or in cash on the first business day 90 days after a separation from service"

beneficial ownership financial

"Ms. Dolan-Sweeney disclaims beneficial ownership of these securities beneficially owned or deemed to be beneficially owned by Mr. Sweeney"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.
