IPG PHOTONICS REPORTS 37 PERCENT REVENUE GROWTH FOR SECOND QUARTER 2007

Leader in Fiber Laser Technology Increases Operating Income by 35 Percent
and Net Income by 33 Percent

OXFORD, Mass. — August 7, 2007— IPG Photonics Corporation (Nasdaq: IPGP), the global leader in high-performance fiber lasers and amplifiers for diverse applications, today reported that revenues for the second quarter of 2007 increased by 37% to $44.0 million, up from $32.2 million for the second quarter of 2006. For the first six months of 2007, revenues increased 32% to $85.7 million from $64.9 million in the first six months of 2006. Results were driven primarily by continued strong sales of the Company’s fiber lasers used for materials processing applications, which increased by 47% over the second quarter of 2006 to $33.9 million.

Operating income increased 35% to $10.1 million for the second quarter of 2007, up from $7.5 million for the same period in 2006. Net income for the second quarter of 2007 increased 33% to $6.4 million from $4.8 million, and earnings per diluted share increased 17% to $0.14 from $0.12. Operating expenses for the second quarter of 2007 increased by $4.4 million to $10.2 million, or 23% of revenue, compared with 18% in 2006, as a result of the growth in the Company’s scale and expenses associated with being a public company.

For the first six months of 2007, operating income increased 41% to $21.2 million, up from $15.0 million for the same period in 2006. Net income increased 67% to $13.0 million from $7.8 million, and earnings per diluted share increased 53% to $0.29 from $0.19.

Please refer to the exhibit to this press release for a reconciliation of adjusted net income and adjusted earnings per share to net income and earnings per share, respectively, for 2006.

Cash and cash equivalents were $46.7 million on June 30, 2007, compared to $75.7 million on December 31, 2006, mainly as a result of the repayment of $18.2 million of term debt and capital expenditures of $17.8 million.

Comments on the Second Quarter

“IPG continued to displace conventional laser technologies in a growing number of applications and industries,” said Dr. Valentin Gapontsev, IPG Photonics’ Chief Executive Officer. “Once again, our operating model delivered improved quarterly financial results. Second quarter growth continued to be driven by increased sales of our high-power fiber lasers in the materials processing market. Our pulsed lasers used for marking applications and our line of low-powered lasers used in medical systems also experienced strong sales gains.”

“IPG reported good sales growth in China this quarter after we opened our new sales and service center in April,” continued Dr. Gapontsev. “Operationally, we continued to build our infrastructure to strengthen our position as the only vertically integrated manufacturer of fiber lasers. Our state-of-the-art, 30,000 square foot semiconductor plant in Massachusetts is now complete and houses the first of several high volume multi-wafer molecular beam epitaxy reactors. We also fully commissioned our new specialty optical fiber plant in Germany, which increases our fiber production capacity and provides us with a new generation of higher performance fibers.”

Business Outlook

“We are pleased that the marketplace has recognized and responded to the superiority of our fiber laser products. We plan to capitalize on this demand,” concluded Dr. Gapontsev.

For the third quarter of 2007, IPG Photonics expects revenues in the range of $44 million to $49 million. The Company anticipates earnings per diluted share in the range of $0.14 to $0.18 based on 45,631,000 common shares, which includes 42,974,000 basic common shares outstanding and 2,657,000 potentially dilutive options at June 30, 2007.

Use of Non-GAAP Financial Measures

In addition to financial measures prepared in accordance with generally accepted accounting principles (GAAP), this press release contains non-GAAP financial measures of adjusted net income and adjusted earnings per share for 2006, in each case excluding the impact of the fair value adjustment to the series B warrants and preferred stock accretion. The Company believes that the inclusion of these non-GAAP financial measures in this press release helps investors to gain a meaningful understanding of growth in the Company’s core operating results and future prospects, and can also help investors who wish to make comparisons between IPG Photonics and other companies. IPG Photonics management uses these non-GAAP measures, in addition to GAAP financial measures, as the basis for measuring its core operating performance and comparing such performance to that of prior periods and to the performance of the Company’s competitors. These measures also are used by management in its financial and operating decision-making.

The non-GAAP financial measures included in this press release are not meant to be considered superior to or a substitute for results of operations prepared in accordance with GAAP. In addition, the non-GAAP financial measures included in this press release may be different from, and therefore may not be comparable to, similar measures used by other companies. Although non-GAAP financial measures used in this release exclude the accounting treatment of the fair value adjustment to the series B warrants and preferred stock accretion, these non-GAAP measures should not be relied upon independently, as they do not reflect the impact that these items have on the Company’s operating results. Reconciliations of the non-GAAP financial measures used in this press release to the most directly comparable GAAP financial measures are set forth in the exhibit to this press release.
