"settled in shares of ONE Gas common stock at the distribution date described in the Plan."

The distribution date is the day a company, fund, or trust actually pays out cash or other assets to its shareholders or unitholders. Think of it as the payday when owners receive dividends, interest, or capital gains distributions; it matters to investors because it determines when you get the money, can affect the security’s price that day, and has tax and cash-flow consequences.
