equity retainer award financial

"Represents the reporting person's annual 2026 equity retainer award."

dividend reinvestment financial

"Includes 50.047 shares acquired pursuant to dividend reinvestment and not previously reported"

Dividend reinvestment is when the money earned from a company's profit sharing, called dividends, is automatically used to buy more shares of that company instead of being received as cash. This process helps investors grow their holdings over time without extra effort, much like using earned interest to buy more of a savings account. It encourages long-term investment growth by continuously increasing the amount of shares owned.

Rule 16a-11 regulatory

"not previously reported pursuant to Rule 16a-11."
