"Represents Common Shares vested on September 1, 2026 in accordance with the issuer's Employee Restricted Stock Awards Rules."

Employee Stock Purchase Plan financial

"Common Shares purchased and held under the issuer's Employee Stock Purchase Plan ("ESPP")."

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.

Long-Term Incentive Bonus Plan financial

"Represents Common Shares purchased by a trust with cash received under the issuer's Long-Term Incentive ("LTI") Bonus Plan, over which the filer has obtained investment control."

investment control financial

"purchased by a trust with cash received under the issuer's Long-Term Incentive ("LTI") Bonus Plan, over which the filer has obtained investment control."
