The reason is that the per-share value is best for people who already own or follow the stock. For example, Twitter employees can quickly ballpark the dollar value of their shares with the $26 number. It's also easier for tracking movement (e.g., $20 last week, $26 this week). It's the same reason that all ticker prices are in per-share value rather than market cap. $XOM at $93.22 means less to me personally than "Exxon Mobil is worth $400 billion," but the per-share value is probably most relevant to people with business interest in Exxon.
