  • Another payments-technology company, Global Payments, added 1% premarket after it said its profit rose for the second quarter, driven by revenue growth in the merchant-solutions business.
  • Smoother sailing ahead? Carnival added 1.5% premarket after the cruise operator said over the weekend that its Princess Cruises had completed its first voyage following an extended pause in operations.
