Management Comments

"IPG delivered record quarterly results, driven by rapid growth in our core products, applications, and geographies," said Dr. Valentin Gapontsev, IPG Photonics' Chief Executive Officer. "As the market leader in fiber lasers, we are benefiting from accelerating adoption of fiber lasers over conventional lasers and non-laser cutting and welding equipment. Second quarter revenue and net income were both at record levels, highlighting the strength of our business model."

Second quarter revenue of $369.4 million increased 46% year over year, and earnings per diluted share ("EPS") of $1.91 increased 53% year over year. Materials processing sales increased 48% year-over-year in the second quarter and accounted for approximately 96% of total sales driven by strength in cutting and welding applications. Sales to other markets were up 19% year-over-year driven by strong sales in telecom. High-power laser sales increased 57% year over year from rapid growth in cutting and welding applications while sales of QCW lasers increased 82% year over year driven by growth in consumer electronics production and percussion hole drilling. While all main geographies other than Japan experienced increases, sales growth in China was particularly strong, almost doubling, and represented half of total revenue in the second quarter.

During the second quarter, IPG generated $82.3 million in cash from operations and used $21.8 million to finance capital expenditures. IPG ended the quarter with $930.4 million in cash and cash equivalents and short-term investments, representing an increase of $99.8 million from December 31, 2016.

Business Outlook and Financial Guidance

"Demand for our core products, particularly high-power, kilowatt-scale fiber lasers, has never been stronger. Our leadership position within this fast-growing market drove record order activity in the quarter, resulting in a book-to-bill ratio above one. Based on these trends and the strength of our current backlog, we believe we are in excellent position to deliver another strong quarter in three months," said Dr. Gapontsev.

IPG Photonics expects revenue in the range of $350 million to $375 million for the third quarter of 2017. The Company anticipates earnings per diluted share in the range of $1.70 to $1.90 based on 54,471,000 diluted common shares, which includes 53,380,000 basic common shares outstanding and 1,091,000 potentially dilutive options at June 30, 2017.

Dr. Gapontsev added, "Year-to-date bookings have exceeded our expectations, pointing to strong revenue growth in 2017. Based on first half outperformance and current backlog, we are now targeting approximately 32% to 34% revenue growth for the full year. Our fourth quarter performance will be driven by order activity through the end of the third quarter and during the fourth quarter, for which our visibility is low. Given the magnitude of outperformance during the first half of the year, we believe it is prudent to assume a lower growth rate in the fourth quarter due to more challenging comparisons and an expected slowdown in spending related to typical seasonality in China and the consumer electronics investment cycle. Should this

anticipated spending slowdown fail to materialize at a level consistent with historic trends, this could result in upside to our full year guidance range."

As discussed in more detail in the "Safe Harbor" passage of this news release, actual results may differ from this guidance due to various factors including, but not limited to, product demand, order cancellations and delays, competition and general economic conditions. This guidance is based upon current market conditions and expectations, and is subject to the risks outlined in the Company's reports with the SEC, and assumes exchange rates relative to the U.S. Dollar of Euro 0.88, Russian Ruble 59, Japanese Yen 112 and Chinese Yuan 6.77, respectively.
