Employee Stock Purchase Plan financial

"Common Shares purchased by the administrator of the issuer's Employee Stock Purchase Plan ("ESPP") on behalf of the filer"

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.

ESPP trust financial

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

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"

open-market purchase financial

"transaction_action": "open-market purchase""

An open-market purchase is when an investor or a company buys shares on a public stock exchange at the going market price, rather than through a private deal. It matters to investors because these purchases change how many shares are available, can push the stock price up or signal confidence from large buyers, and often affect per-share metrics like earnings—think of it like someone buying lots of apples off a grocery shelf, reducing supply and potentially raising the price.
