SAN JOSE, CA – November 1, 2012 –NeoPhotonics Corporation (NYSE: NPTN), a leading designer and manufacturer of photonic integrated circuit, or PIC, based modules and subsystems for bandwidth-intensive, high speed communications networks, today announced financial results for its third quarter ended September 30, 2012.

“We are very pleased with our performance in the third quarter delivering 54% year-over-year revenue growth, and returning to profitability ahead of our initial projection schedule made at the time of the Santur acquisition,” said Tim Jenks, Chairman, President and CEO of NeoPhotonics. “We experienced growth from several Western customers, notably in Coherent and other high speed products, where we have a breadth of design wins that propelled us to another record quarter.”

Highlights for the Third Quarter of 2012

• Revenue was $66.2 million, up $3.1 million, or 5%, from the prior quarter & up $23.3 million, or 54%, from the third quarter 2011

• Gross margin was 31.2%, up from 24.8% in the prior quarter & 28.1% in the third quarter 2011

• Non-GAAP gross margin was 32.9%, up from 26.5% in the prior quarter & 27.8% in the third quarter 2011

• Income from continuing operations was $0.7 million, up $4.4 million from the prior quarter’s loss of $3.7 million and up from a loss of $4.2 million in the third quarter 2011

• Non-GAAP income from continuing operations was $2.7 million, up $4.4 million from the prior quarter’s loss of $1.7 million and up from a loss of $3.2 million in the third quarter 2011

• Non-GAAP diluted income per share from continuing operations was $0.08, up from a loss of $0.06 in the prior quarter & a loss of $0.13 in the third quarter 2011

• Adjusted EBITDA was $6.4 million, up from $1.8 million in the prior quarter & an adjusted EBITDA loss of $0.5 million in the third quarter 2011

Total cash, cash equivalents and short-term investments was $105.9 million at the end of the third quarter 2012, down from $107.1 million in the prior quarter. The slight decrease in cash was primarily due to scheduled debt repayment and capital expenditures that were substantially offset by strong collections in the quarter.

A reconciliation of GAAP financial measures to Non-GAAP financial measures is attached to this press release. See “Use of Non-GAAP Financial Information” below for a description of these Non-GAAP financial measures.

Outlook for the Quarter Ending December 31, 2012 and Full Year 2013

The company’s current expectations for the fourth quarter 2012 are:

• Revenue in the range of $58 million to $62 million, primarily reflecting seasonality in the business

• Non-GAAP gross margin in the range of 29% to 31%, primarily depending on product mix and the impact of pricing negotiations that take place in the quarter

• Diluted loss per share from continuing operations in the range of $0.06 to $0.13, and on a Non-GAAP basis in the range of break-even to plus or minus $0.05 per share.

The Non-GAAP outlook excludes the expected amortization of intangibles and other assets of approximately $1.7 million and the anticipated impact of stock-based compensation of approximately $1.4 million, of which $1.1 million is estimated to relate to cost of goods sold.

The company’s current expectations for the full year of 2013 are for revenue growth in the range of 8% to 10% over 2012, and with that level of growth, profitability on an annual basis.

included under GAAP, including stock-based compensation expense, amortization of purchased intangible assets, amortization of acquisition-related fixed asset set-up, acquisition-related costs, restructuring charges, fair value adjustment to contingent consideration, and the related tax effects of Non-GAAP adjustments. In computing adjusted EBITDA, the company also excludes interest income and expense, provision for income taxes and depreciation expense.

Management uses these Non-GAAP financial measures to evaluate the operating performance of the business and aid in the period-to-period comparability.

The company’s Non-GAAP financial measures are not measurements of financial performance under GAAP, and should not be considered as alternatives to the financial measures derived in accordance with GAAP. The company does not consider these Non-GAAP financial measures to be a substitute for, or superior to, the information provided by GAAP financial results.
