"Strong demand for IPG's high-power lasers for materials processing applications, particularly in Asia and the U.S., drove a 22% year-over-year sales increase during the second quarter," said Dr. Valentin Gapontsev, IPG Photonics' Chief Executive Officer. "Gross margins of 53.5% were within our target range and net income increased 11%. The strong revenue growth during the quarter further demonstrates the increasing adoption rate of fiber laser technologies for various applications. Excluding foreign exchange rate gains, operating income grew by 12.6%. While this was lower than the growth in revenue, it reflects our investment in operating expenses to support IPG's future growth."
