Revenue increased by 28% to $41.8 million for the first quarter of 2007 from $32.7 million for the first quarter of 2006 primarily driven by sales to materials processing applications, which increased by 53% to $33.2 million.

For the first quarter of 2007 as compared to the same period in 2006, operating income increased 48% to $11.1 million from $7.5 million, net income increased 113% to $6.6 million from $3.1 million, and earnings per diluted share increased 114% to $0.15 from $0.07. Operating expenses increased by $3.3 million to $8.3 million or 20% of revenue as a result of the growth in revenues and expenses associated with being a public company.

There were no adjustments to net income and earnings per share in the first quarter of 2007. For the first quarter of 2006, adjusted net income was $4.9 million and adjusted earnings per diluted share were $0.13. Adjusted net income and adjusted earnings per share for the first quarter of 2006 are non-GAAP measures that exclude a $1.9 million charge related to the change in the fair value of the Company’s series B warrants and $0.5 million in accretion related to preferred stock. 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 $49.1 million at March 31, 2007, a decrease of $26.5 million from December 31, 2006 mainly as a result of the repayment of $18.2 million of term debt and capital expenditures of $7.3 million.

Comments on the First Quarter

“IPG has continued to solidly execute on its business plan in the first quarter of 2007 as we reported another quarter of strong top- and bottom-line performance,” said Dr. Valentin Gapontsev, IPG Photonics’ Chief

IPGP Q1 Results/2

Executive Officer. “Our first-quarter growth was driven by increased sales of fiber lasers into the materials processing market, particularly our high-power kilowatt lasers in automotive cutting and welding, as well as our pulsed lasers for marking applications,” continued Dr. Gapontsev.

“Leverage in our operating model drove substantially improved financial results, particularly a 48% increase in operating income,” stated Dr. Gapontsev. “We continue to make important progress on our growth strategy, including displacing existing laser technologies as our fiber laser products gain traction with a growing number of customers.”

Outlook

For the second quarter of 2007, IPG Photonics expects revenues in the range of $42 million to $45 million. The Company anticipates earnings per diluted share in the range of $0.14 to $0.17 based on 45,602,000 common shares, which includes 42,909,000 basic common shares outstanding and 2,693,000 potentially dilutive options.

“We remain enthusiastic about our prospects for strong performance throughout 2007. We are executing well on our strategy and demand for our products remains robust,” concluded Dr. Gapontsev.

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.
