"We are extremely pleased to have achieved this landmark revenue level in the quarter that marks our tenth anniversary as a public company. Our approximately 25% year-over-year increase in fourth-quarter revenue was primarily driven by the continued strong performance of materials processing. Geographically, we saw our strongest growth in Asia and Europe. In terms of products, growth was primarily driven by high-power fiber lasers, QCW lasers, pulsed lasers and amplifiers used in telecommunications applications. We look forward to providing our full fourth-quarter results, an update on our strategic progress and guidance for the first quarter of 2017 on our regular fourth-quarter conference call on February 14."</font></div><div><a name="sC9ABD39FBCC15EBA678DB35CDEEAA086"></a></div><div style="line-height:120%;padding-top:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-weight:bold;">Conference Call Reminder</font></div><div style="line-height:120%;padding-top:6px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company will hold a conference call to review its financial results and business highlights as well as revenue and earnings per share guidance for the first quarter of 2017 on Tuesday, February 14, 2017 at 10:00 a.m. ET.
