"We enter the second half of the year with a healthy pipeline and continued momentum across both new customers and our existing installed base," Chief Executive Ronen Samuel said.

For the current quarter, Kornit guided for revenue of $55 million to $60 million. Analysts were looking for $55.2 million.
