Revenues in the third quarter of fiscal 2009 include $1.9 million recognized upon collection of cash from shipments made to Nortel Networks and a related contract manufacturer in the second quarter of fiscal 2009. An aggregate of $5.4 million in revenue related to shipments to these customers (including the $1.9 million recognized in this quarter), had been deferred from recognition as revenues in the second quarter of fiscal 2009 as payment was not deemed to be collectable at the time of shipment.

Gross margin for the third quarter of fiscal 2009 was 23 percent, compared to gross margin of 17 percent in the second quarter of fiscal 2009, and gross margin of 22 percent in the third quarter of fiscal 2008. Excluding the $1.9 million positive impact from the recognition of revenues on prior quarter shipments described above, gross margin for the third quarter of fiscal 2009 was 20 percent.

Net loss in the third quarter of fiscal 2009 was $13.3 million, or a net loss of $0.13 per share, compared with a net loss of $6.5 million, or a net loss of $0.06 per share, in the second quarter of fiscal 2009 and a net loss of $5.4 million, or a net loss of $0.05 per share, in the third quarter of fiscal 2008. The third quarter fiscal 2009 net loss includes $4.0 million from a non-cash charge for impairment of intangible assets and $3.7 million of expense for legal settlement and related costs. The second quarter fiscal 2009 net loss included a non-cash gain of $9.9 million from the translation to United States dollars of foreign currency denominated balances on the balance sheets of certain foreign subsidiaries and a non-cash charge of $7.9 million from an impairment of goodwill.

Cash, cash equivalents, short-term investments and restricted cash at March 28, 2009 were $38.3 million compared to $44.7 million at December 27, 2008.

Third Quarter Fiscal 2009 Non-GAAP Results

Adjusted EBITDA for the third quarter of fiscal 2009 was negative $0.7 million, compared to negative $3.3 million in the second quarter of fiscal 2009, and negative $1.1 million in the third quarter of fiscal 2008. Adjusted EBITDA for the third quarter of fiscal 2009 included a $1.9 million positive impact from the recognition of revenues on prior quarter shipments described above.

Non-GAAP gross margin was 24 percent in the third quarter of fiscal 2009, compared to 19 percent in the second quarter of fiscal 2009 and 23 percent in the third quarter of fiscal 2008. Non-GAAP gross margin in third quarter of fiscal 2009 excludes $0.3 million of stock based compensation. Excluding the $1.9 million positive impact from the recognition of revenues on prior quarter shipments described above, non-GAAP gross margin in the third quarter of fiscal 2009 would have been 21 percent.

Non-GAAP net loss for the third quarter of fiscal 2009 was $4.4 million, or non-GAAP net loss of $0.04 per share. This compares with a non-GAAP net income of $3.3 million or non-GAAP net income of $0.03 per share, in the second quarter of fiscal 2009 and a non-GAAP net loss of $3.4 million, or non-GAAP net loss of $0.03 per share, in the third quarter of fiscal 2008.

A reconciliation table of non-GAAP measures to the most comparable GAAP measures is included in the financial tables section of this release and further discussion of these measures is also included later in this release.

Non-cash stock-based compensation expense for the third quarter of fiscal 2009, second quarter of fiscal 2009 and third quarter of fiscal 2008 was $1.1 million, $1.0 million and $1.2 million, respectively.

“Despite the lower third quarter revenues that were driven by the economic downturn, we held our adjusted EBITDA close to break even,” said Alain Couder, president and CEO of Oclaro, Inc. “We continued to execute throughout our business as we positioned ourselves towards achieving our goal of profitability. Moving forward, we expect the merger with Avanex Corporation, which closed today, to further accelerate our progress towards profitability. Under our new corporate name, “Oclaro,” our combined companies are well positioned to leverage our complementary product portfolios, operational synergies and strong balance sheet to accelerate our progress to our long-term financial model.”

Non-GAAP Financial Measures

To provide investors with the opportunity to use the same financial metrics as management to evaluate the Company’s performance, the Company provides certain supplemental non-GAAP financial measures, including: 1) non-GAAP net income/loss excluding non-cash stock and option-based compensation, charges such as impairment and restructuring, income taxes, and expenses or income from certain legal actions, settlements and related costs outside the ordinary course of business; 2) a measure of Adjusted EBITDA, that also excludes these charges, plus, among others, the impact of net interest income/expense, depreciation and amortization, impairment of short-term investments and net foreign currency translation gain/loss; 3) non-GAAP operating loss that excludes amortization of intangible assets, non-cash stock and option-based compensation, charges such as impairment and restructuring, and expenses or income from certain legal actions, settlements and related costs outside the normal course of business; and 4) non-GAAP gross margin that excludes Non-GAAP gross margin rate is calculated as gross margin rate as determined in accordance with GAAP (gross profit as a percentage of revenues) excluding non-cash compensation related to stock and options; and certain other significant non-recurring one-time charges and credits specifically identified in the non-GAAP reconciliation schedules set forth below. These are made available to investors to allow them the opportunity to use the same financial metrics as management to evaluate the Company’s performance. Oclaro also believes these non-GAAP measures enhance the comparability and transparency of results for the periods reported. These measures should be considered in addition to results prepared in accordance with accounting principles generally accepted in the United States (“GAAP”), but should not be considered a substitute for, or superior to, GAAP results.

Non-GAAP Net Income/Loss

Non-GAAP net income/loss is calculated as net income/loss excluding the impact of restructuring and severance costs, non-cash compensation related to stock and options granted to employees and directors, income taxes, impairment charges and certain other one-time charges and credits specifically identified in the non-GAAP reconciliation schedules set forth below. The Company evaluates its performance using, among other things, non-GAAP net income/loss in evaluating the Company’s historical and prospective operating financial performance, as well as its operating performance relative to its competitors. Specifically, management uses this non-GAAP measure to further understand the Company’s “core operating performance.” The Company believes its “core operating performance” represents the Company’s on-going performance in the ordinary course of its operations. Accordingly, management excludes from “core operating performance” those items, such as impairment charges, income taxes, restructuring and severance programs and costs relating to specific major projects which are non-recurring, expenses or income from certain legal actions, settlements and related costs, as well as non-cash compensation related to stock and options. Management does not believe these items are reflective of the Company’s ongoing operations and accordingly excludes those items from non-GAAP net income/loss.

The Company believes that providing non-GAAP net income/loss to its investors, in addition to corresponding income statement measures, provides investors the benefit of viewing the Company’s performance using the same financial metrics that the management team uses in making many key decisions and understanding how the core business and its results of operations may look in the future. The Company further believes that providing this information allows the Company’s investors greater transparency and a better understanding of the Company’s core financial performance. Additionally, non-GAAP net income/loss has historically been presented by the Company as a complement to net loss, thus increasing the consistency and comparability of the Company’s earnings releases. The non-GAAP adjustments, and the basis for excluding them, are discussed further below.

Non-GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States. Non-GAAP net income/loss should not be considered in isolation from or as a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from non-GAAP net income/loss used by other companies. The GAAP measure most directly comparable to non-GAAP net income/loss is net income/loss. A reconciliation of non-GAAP net income/loss to GAAP net income/loss is set forth in the schedules below.

Adjusted EBITDA

Adjusted EBITDA is calculated as net income/loss excluding the impact of taxes, net interest income/expense, depreciation and amortization, net foreign currency translation gains/losses, as well as restructuring and severance, impairment, non-cash compensation related to stock and options, expenses or income from certain legal actions, settlements and related costs outside our normal course of business and certain other one-time charges and credits specifically identified in the non-GAAP reconciliation schedules set forth below. The Company uses Adjusted EBITDA in evaluating the Company’s historical and prospective cash usage, as well as its cash usage relative to its competitors. Specifically, management uses this non-GAAP measure to further understand and analyze the cash used in/generated from the Company’s core operations. The Company believes that by excluding these non-cash and non-recurring charges, more accurate expectations of its future cash needs can be assessed in addition to providing a better understanding of the actual cash used in or generated from core operations for the periods presented.

Management does not believe the excluded items are reflective of the Company’s ongoing operations and accordingly excludes those items from Adjusted EBITDA. The Company believes that providing Adjusted EBITDA to its investors, in addition to corresponding GAAP cash flow measures, provides investors the benefit of viewing the Company’s performance using the same financial metrics that the management team uses in making many key decisions that impact the Company’s cash position and understanding how the cash position may look in the future. The Company further believes that providing this information allows the Company’s investors greater transparency and a better understanding of the Company’s core cash position.

Non-GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles (GAAP) in the United States. Adjusted EBITDA should not be considered in isolation from or as a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from non-GAAP measures used by other companies. The GAAP measure most directly comparable to Adjusted EBITDA is net income/loss. A reconciliation of Adjusted EBITDA to GAAP net income/loss is set forth in the financial schedules section below.

Non-GAAP Gross Margin Rate

Non-GAAP gross margin rate is calculated as gross margin rate as determined in accordance with GAAP (gross profit as a percentage of revenues) excluding non-cash compensation related to stock and options; and certain other significant non-recurring one-time charges and credits specifically identified in the non-GAAP reconciliation schedules set forth below.

The Company evaluates its performance using non-GAAP gross margin rate to assess the Company’s historical and prospective operating financial performance, as well as its operating performance relative to its competitors. Specifically, management uses this non-GAAP measure to further understand the Company’s “core operating performance.” The Company believes its “core operating performance” represents the Company’s on-going performance in the ordinary course of its operations. Accordingly, management excludes from “core operating

performance” those items such as non-cash compensation related to stock and options; and certain other significant non-recurring one-time charges and credits specifically identified. Management does not believe these items are reflective of the Company’s ongoing operations and accordingly excludes those items from non-GAAP gross margin rate.

The Company further believes that providing this information allows the Company’s investors greater transparency and a better understanding of the Company’s core financial performance. The non-GAAP adjustments, and the basis for excluding them, are discussed further below.

Non-GAAP gross margin rate should not be considered in isolation from or as a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from non-GAAP gross margin rate used by other companies. The GAAP measure most directly comparable to non-GAAP gross margin rate is gross margin rate. A reconciliation of non-GAAP gross margin rate to GAAP gross margin rate is set forth in the schedules below.

Non-GAAP Operating Loss

Non-GAAP operating loss is calculated as operating loss as determined in accordance with GAAP excluding the impact of amortization of intangible assets, restructuring and severance costs, non-cash compensation related to stock and options granted to employees and directors, impairment charges, and certain other one-time charges and credits specifically identified in the non-GAAP reconciliation schedules set forth below. The Company evaluates its performance using, among other things, non-GAAP operating loss in evaluating the Company’s historical and prospective operating financial performance, as well as its operating performance relative to its competitors.

Furthermore, similar non-GAAP measures to those referenced above have historically been presented by the Company as a complement to its GAAP presentation. The non-GAAP adjustments, and the basis for excluding them, are discussed further below.

Stock-Based Compensation

The Company incurs certain non-cash expenses, which are included in its GAAP statement of operations, for stock-based compensation in accordance with the requirements of SFAS No. 123R, Share-Based Payment. The Company excludes this item, for the purposes of calculating non-GAAP net income (loss), Adjusted EBITDA, non-GAAP gross margin rate and non-GAAP operating loss when it evaluates the continuing core operational performance of the Company. The Company believes that these amounts do not reflect expected future operating expenses nor does the Company believe that they provide a meaningful evaluation of current versus past core operational performance.

Restructuring and Severance Activities

The Company has incurred expenses, which are included in its GAAP statement of operations, primarily due to the write-down of certain property and equipment that has been identified for disposal, workforce related charges such as severance, benefits and employee relocation costs related to formal restructuring plans, termination costs and building costs for facilities not required for ongoing operations, and costs related to the relocation of certain facilities and equipment from buildings which the Company has disposed of or plans to dispose of. The Company excludes these items, for the purposes of calculating non-GAAP net income/loss, Adjusted EBITDA and non-GAAP operating loss, when it evaluates the continuing operational performance of the Company. The Company does not believe that these items reflect expected future operating expenses nor does it believe that they provide a meaningful evaluation of current versus past core operational performance.

Certain Legal Actions, Settlement and Related Costs

In the second and third quarters of fiscal 2009, the Company recorded expenses of $0.3 million and $3.7 million, respectively, related to the settlement of outstanding litigation with JDS Uniphase Corporation on April 10, 2009. Of these amounts, $3.0 million is paid or payable to JDS Uniphase and $1.0 million relates to legal costs incurred by the Company related to this litigation. In the first quarter of fiscal 2009, the Company recorded a gain of $0.2 million, net of costs incurred, related to the settlement of a legal action against a third party in connection with land sold by the Company in 2006, net of insurance recoveries, both of which are included in its GAAP statement of operations. The Company excludes these items for the purposes of calculating non-GAAP net income/loss, Adjusted EBITDA and non-GAAP operating loss when it evaluates the continuing performance of the Company. The Company does not believe that these items reflect expected future expenses nor does it believe they provide a meaningful evaluation of current versus past core operational performance.

Amortization of Intangible Assets

In connection with the purchase accounting for its acquisition of numerous companies and businesses Company recorded intangible assets which are being amortized to operating expenses over their useful lives. The Company excludes the amortization of intangible assets for the purposes of calculating non-GAAP operating loss and Adjusted EBITDA when it evaluates the continuing core operational performance of the Company. The Company believes that these items do not reflect expected future operating expenses nor does the Company believe that they provide a meaningful evaluation of current versus past core operational performance.

Foreign Currency Translation Gains/Losses

The Company records gains and losses related to the translation of intercompany balances denominated in currencies other than the functional currencies of the Company’s local legal entities, the translation of certain other ending balance sheet accounts denominated in currencies other than the functional currencies of the Company’s local legal entities, and contracts entered into to mitigate the exposure to these translation gains and losses. The Company excludes this item, for the purposes of calculating Adjusted EBITDA, when it evaluates the cash usage and prospective cash usage of the Company. Management does not believe this excluded item is reflective of its ongoing operations.

Goodwill and Intangibles Impairment

As part of the Company’s preparation of its financial statements for the second quarter of fiscal 2009, the Company determined that the value of its goodwill was impaired. During the second fiscal quarter, there was a decline in the revenue forecasts for the optical components industry, with a corresponding reduction in the Company’s market capitalization and revenue projections. These were some of the factors that triggered the impairment of goodwill. Based on the results of a preliminary evaluation, the Company recorded a non-cash impairment charge of $7.9 million in the second quarter of fiscal 2009. During the third quarter of fiscal 2009, the Company completed its full evaluation of the impairment analysis for goodwill, which indicated that the goodwill of $7.9 million was fully impaired. The impairment will not result in any current or future cash expenditures.

During the third quarter of fiscal 2009, in conjunction with the full evaluation of goodwill impairment, the Company also evaluated the fair value of certain intangible assets. Based on this testing, the Company recorded a non-cash impairment charge of $4.0 million in its third quarter statement of operations to recognize impairment of certain intangible assets.

The Company excludes these items for the purposes of calculating non-GAAP net income/loss, Adjusted EBITDA and non-GAAP operating loss when it evaluates the continuing performance of the Company. The Company does not believe that these items reflect expected future expenses nor does it believe they provide a meaningful evaluation of current versus past core operational performance.

Non-GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States of America. Non-GAAP measures should not be considered in isolation from or as a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from non-GAAP measures used by other companies. The GAAP measure most directly comparable to non-GAAP net income/loss is net income/loss. The GAAP measure most directly comparable to Adjusted EBITDA is net income/loss. The GAAP measure most directly comparable to non-GAAP gross margin rate is gross margin rate. The GAAP measure most directly comparable to non-GAAP operating loss is operating loss. A reconciliation of each of these non-GAAP financial measures to GAAP information is set forth below.
