reinvested dividends financial

"shares acquired during the first and second quarters of 2026 through reinvested dividends"

Reinvested dividends are payouts a shareholder receives from a company that are automatically used to buy additional shares instead of being taken as cash. For investors this acts like planting dividends back into the portfolio so each future payout can come from a slightly larger holding, helping returns compound over time and showing the difference between income you spend today and total growth of your investment.

par value financial

"Common Stock, $.01 Par Value"

Par value is the fixed amount printed on a bond or stock that represents its original value when issued. It’s like the face value of a coin or bill—what the issuer promises to pay back or the starting price of a stock—though it often doesn’t change with market prices. It matters because it helps determine certain financial details, like how much the company will pay back at maturity.

open-market or private transaction financial
