·GAAP Gross margin of 41.0%; Non-GAAP Gross margin of 45.8%

·GAAP EPS of $(0.05); Non-GAAP EPS of $0.15

Milpitas, California, October 30, 2012 JDSU (NASDAQ: JDSU, and TSX: JDU) today reported results for its fiscal 2013 first quarter ended September 29, 2012.

GAAP net revenue for the quarter was $420.9 million and net loss was $(11.6) million, or $(0.05) per share.  Prior quarter net revenue was $434.0 million, with a net loss of $(22.2) million, or $(0.10) per share. Net revenue for the fiscal 2012 first quarter was $415.8 million, with a net loss of $(5.8) million, or $(0.03) per share.

Non-GAAP net revenue for the quarter was $420.9 million and net income was $35.0 million or $0.15 per share.  Prior quarter non-GAAP net revenue was $434.0 million, with a net income of $35.4 million, or $0.15 per share. Non-GAAP net revenue for the fiscal 2012 first quarter was $416.1 million, with a net income of $41.2 million or $0.18 per share.

“Our solid fiscal Q1 results reflect JDSU’s ability to deliver to its commitments even during periods of economic uncertainty,” said Tom Waechter, JDSU’s President and Chief Executive Officer.

“Communications service providers continue to spend cautiously due to macro-economic and geo-political concerns.  Because of this uncertain climate, we are not projecting the calendar year-end budget release that frequently occurs in the Telecom industry.  Looking forward, we are encouraged by the relentless broadband demand that remains a powerful driver for JDSU’s core business.  Our ability to differentiate through product innovation, evolve our variable cost model, and maintain a robust balance sheet means that we are well positioned to capitalize on future growth opportunities as the gap closes between demand and actual spending by our core network customers.”

Forward-Looking Statements

This press release contains, and the discussions in our subsequent conference call will contain, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements include: (i) any anticipation or guidance as to future financial performance, including future revenue, gross margin, operating expense, operating margin, cash flow and other financial metrics, and the impact and duration of

certain market conditions; and (ii) the Company’s beliefs regarding the purpose, usefulness and efficacy of non-GAAP results and the measures and items the Company includes in the same, as well as any benefits to investors the Company believes its non-GAAP measures provide.  These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected. In particular, the Company’s ability to predict future financial performance continues to be difficult due to, among other things:  (a) continuing general limited visibility across many of our product lines, as well as the migration to vendor managed inventory programs; (b) quarter-over-quarter product mix fluctuations, which can materially impact profitability measures due to the broad gross margin range across our portfolio; (c) consolidation of our customer base, which, in the shorter term limits demand visibility, and in the longer term, could reduce our business potential; (d) continued decline of average selling prices across our businesses; (e)  notable seasonality and a significant level of in-quarter book-and-ship business, particularly in Communications Test and Measurement business; (f)  various product and manufacturing transfers, site consolidations and product discontinuances in which we are currently engaged, that have caused and may cause short term disruptions; (g) the ability of our suppliers and contract manufacturers to meet production and delivery requirements to our forecasted demand; and (h) inherent uncertainty related to global markets and the effect of such markets on demand for our products.

For more information on these and other risks affecting the Company’s business, please refer to the “Risk Factors” section included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2012 filed with the Securities and Exchange Commission.

Use of Non-GAAP (Adjusted) Financial Measures

The Company provides non-GAAP net revenue, non-GAAP net income (loss), non-GAAP net income (loss) per share, EBITDA and adjusted EBITDA financial measures as supplemental information regarding the Company’s operational performance.  The Company uses the measures disclosed in this release to evaluate the Company’s historical and prospective financial performance, as well as its performance relative to its competitors.  Specifically, management uses these items to further its own understanding of the Company’s core operating performance, which the Company believes represents its performance in the ordinary, ongoing and customary course of its operations.  Accordingly, management excludes from core operating performance items such as those relating to amortization of acquisition-related intangibles, stock-based compensation, restructuring and certain investing expenses and non-cash activities that management believes are not reflective of such ordinary, ongoing and customary course activities.

The Company believes providing this additional information to its investors allows investors to see Company results through the eyes of management.  The Company further believes that providing this information allows Company investors to both better understand the Company’s financial performance and, importantly, to evaluate the efficacy of the methodology and information used by management to evaluate and measure such performance.

The non-GAAP adjustments described in this release have historically been excluded by the Company from its non-GAAP financial measures. The non-GAAP adjustments, and the basis for excluding them, are outlined below.

Revenue from acquisition-related deferred revenue: The Company excludes the fair value adjustment to acquisition-related deferred revenue when calculating non-GAAP revenue.  The Company believes non-GAAP revenue provides useful information for investors as they review for underlying trends in the business and facilitates the investors’ comparisons of the Company’s revenue performance to prior and future periods and to the Company’s peers.

Cost of sales, costs of research and development and costs of selling, general and administrative: The Company GAAP presentation of gross margin and operating expenses may include (i) additional depreciation from changes in estimated useful life and the write-down of certain property and equipment that has been identified for disposal but remained in use until the date of disposal, (ii) workforce related charges such as severance, retention bonuses and employee relocation costs related to formal restructuring plan, (iii) costs for facilities not required for ongoing operations, and costs related to the relocation of certain equipment from these facilities and/or contract manufacturer facilities, (iv) stock-based compensation, and (v) other non-recurring charges comprising mainly of, one-time acquisition, integration, litigation and other costs and contingencies unrelated to current and future operations. The Company excludes these items in calculating non-GAAP gross margin, non-GAAP operating income, non-GAAP net income (loss), non-GAAP net income (loss) per share, EBITDA and adjusted EBITDA.  The Company believes excluding these items enables investors to evaluate more clearly and consistently the Company’s core operational performance.

Amortization of intangibles from acquisitions: The Company includes amortization expense related to intangibles from acquisitions in its GAAP presentation of cost of sales and operating expense. The Company excludes these significant non-cash items in calculating non-GAAP gross margin, non-GAAP operating income, non-GAAP net income (loss), non-GAAP net income (loss) per share, EBITDA and adjusted EBITDA because it believes doing so provides investors a clearer and more consistent view of the Company’s core operating performance in terms of cost of sales and operating expenses.

Other income (loss), net and non-cash interest expense: The Company incurred a loss in connection with repurchasing certain of its 1% Senior Convertible Notes which was recorded in interest and other (income), net in compliance with the authoritative guidance. The Company also incurred non-cash interest expense accounted for under the authoritative guidance on convertible debt instruments, which requires the Company to separately account for the liability (debt) and equity (conversion option) components of such instruments. The Company eliminates these items in calculating non-GAAP net income (loss), non-GAAP net income (loss) per share, EBITDA and adjusted EBITDA, because it believes that in so doing, it can provide investors a clearer and more consistent view of the Company’s core operating performance.

Gain or loss on sale of available for-sale investments: The Company has sold investments or adjusted the value of investments from time to time based on market conditions, and includes the impact of these activities in its GAAP presentation of net income (loss) and net income (loss) per share.  The Company’s core business does not include making financial investments in third parties, and such investments do not constitute a material portion of the Company’s assets.  Moreover, the amount and timing of gains and losses and adjustments to the value of investments are unpredictable. Consequently, the Company excludes these items in calculating non-GAAP net income (loss), non-GAAP net income (loss) per share, EBITDA and adjusted EBITDA because it believes gains or losses on these sales and adjustments to the value of investments are not related to the Company’s ongoing core business and operating performance.

Discontinued operations: The Company has adjusted its current and historical Consolidated Statements of Operations and segment financials to reflect the October 2012 sale of its holographic security business. This business’ adjusted results are reflected as discontinued operations for the periods reported in the Company’s GAAP consolidated statement of operations. The Company excluded the results of discontinued operations in calculating non-GAAP net income (loss), non-GAAP net income (loss) per share, EBITDA and adjusted EBITDA for all periods reported.  The Company believes excluding these items enables investors to evaluate more clearly and consistently the Company’s core operational performance.

Interest, taxes, depreciation, amortization and other adjustments:  The Company’s EBITDA calculation excludes interest, taxes, depreciation and amortization, and other items that are not part of its core operating performance described above.  Management believes adjusted EBITDA is a good indicator of the Company’s core operational cash flow.

Non-GAAP financial measures are not in accordance with, or an alternative for, generally accepted accounting principles in the United States.  The GAAP measure most directly comparable to non-GAAP net income (loss) is net income (loss). The GAAP measure most directly comparable to non-GAAP net income (loss) per share is net income (loss) per share.  The Company believes these GAAP measures alone are not indicative of its core operating expenses and performance.

The following tables reconcile GAAP measures to non-GAAP measures:
