Samsung and Corning published first-quarter 2019 earnings this week, and again posted good results in the telecom vertical. Samsung’s mobile infrastructure revenue were up 54% from the same quarter a year ago to $1.14 billion, due to early 5G rollouts in Korea. Corning’s optical fiber sales to carriers were up 15% year over year to $776 million, due to Verizon purchases, mobile densification projects and the acquisition of 3M’s small fiber business.
Both companies are solidly optimistic about future growth. Corning says the performance of its optical communications divisions “continues to be outstanding,” and expects $5 billion in annual sales next year.
