Sales and earnings results exceeded our previously communicated guidance ranges and strong free cash flow allowed us to reduce our net debt leverage ratio to 2.5x,” said Anders Gustafsson, CEO of Zebra Technologies. “Given the strength of our results, we are raising our full-year outlook for sales growth and free cash flow. We continue to deliver digital innovation that enables our customers to compete effectively in today’s on-demand economy.”
