"Class A Common Stock held in a 401(k) unitized stock fund."

Stock Appreciation Rights financial

"307,707 shares of Class A Common Stock issued as Stock Appreciation Rights."

Stock appreciation rights (SARs) are a form of employee compensation that give the holder the right to receive the increase in a company's stock price over a set baseline, paid in cash or shares, without having to buy the stock. For investors, SARs matter because they can create future cash outflows or share dilution and signal how a company rewards and motivates executives — similar to giving a bonus tied directly to how well the company’s stock performs.

Employee Stock Purchase Plan financial

"Class A Common Stock held in an Employee Stock Purchase Plan."

An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
