"based on our total stockholder return during the performance periods"

Total stockholder return is the percentage gain or loss an investor would have experienced over a period from both changes in a stock’s price and any cash payouts such as dividends, assuming those payouts are reinvested in the stock. It matters because it shows the complete financial outcome of owning a share — like measuring both a house’s change in sale value and the rent you collected — and lets investors fairly compare performance across companies and time.
