JDS UNIPHASE REPORTS FIRST QUARTER RESULTS

San Jose, California, October 23, 2003 - JDS Uniphase Corporation (NASDAQ: JDSU and TSX: JDU) today reported results for its first quarter of fiscal year 2004 ended September 30, 2003.

Net revenue for the first quarter was $147.4 million, compared to net revenue of $160.6 million for the quarter ended June 30, 2003 and net revenue of $193 million for the quarter ended September 30, 2002.

The Company reported a reduced net loss of $28.1 million, or $0.02 per share, for the quarter ended September 30, 2003, as compared to a net loss of $61.6 million, or $0.04 per share, for the quarter ended June 30, 2003, and a net loss of $520.5 million, or $0.37 per share, for the quarter ended September 30, 2002.

On a non-GAAP basis, the Company reported a reduced net loss of $13.5 million, or $0.01 per share, for the quarter ended September 30, 2003, as compared to a net loss of $22.3 million, or $0.02 per share for the quarter ended June 30, 2003, and a net loss of $62.4 million, or $0.04 per share, for the quarter ended September 30, 2002. Non-GAAP results exclude the following: restructuring and other charges associated with the Global Realignment Program; the cumulative effect of an accounting change; amortization of purchased intangibles; reductions of long-lived assets; stock-based compensation charges; gains and losses on sale of subsidiaries' assets; and gains and losses on investments.

On a non-GAAP EBITDA basis (non-GAAP loss from operations excluding depreciation), the Company's net loss was $18.7 million for the quarter ended September 30, 2003, down from $24.7 million for the quarter ended June 30, 2003, and $55.7 million for the quarter ended September 30, 2002.

"The leadership transition has progressed smoothly, and progress on reducing losses has been steady, driven by our imperative to be well poised for a stabilizing market," said Kevin Kennedy, CEO. "Throughout this transition and beyond we are making deliberate choices intended to ensure the success of JDS Uniphase as a leader in the industry with a customer-driven focus on operational excellence and profitability."

Use of Non-GAAP Financial Measures

The Company provides non-GAAP financial measures to supplement its consolidated financial statements presented in accordance with GAAP. These non-GAAP financial measures are intended to supplement the user's overall understanding of the Company's current financial performance and its prospects for the future. Specifically, the Company believes the non-GAAP results provide useful information to both management and investors by identifying certain expenses, gains and losses that, when excluded from the GAAP results, may provide additional understanding of the Company's core operating results or business performance. However, these non-GAAP financial measures are not intended to supercede or replace the Company's GAAP results. A detailed reconciliation of the GAAP results to the non-GAAP results is provided in the "Non-GAAP Condensed Consolidated Statements of Operations" and "Additional Non-GAAP Selected Financial Information" schedules below.

Financial Overview - First Quarter Ended September 30, 2003

Global Realignment Program

The Company is continuing its restructuring activities under the Global Realignment Program in response to business conditions. The Company reported the following progress and expectations in connection with the Global Realignment Program:

Business Outlook

The Company anticipates revenue for the second quarter of fiscal 2004 will be in the range of $140 to $150 million. The Company expects non-GAAP gross margin will be in the range of 19% to 21% of total revenue, with a non-GAAP net loss of $0.02 to $0.03 per share. The Company expects to complete cost reductions under which the Company would breakeven, on a non-GAAP EBITDA basis, at a revenue threshold of $200 million in the second quarter of fiscal 2004, and at a revenue threshold of $170 million in the fourth quarter of fiscal 2004. Please note that these breakeven levels are indicative of expected improvements to the cost structure and are not intended as revenue projections. The Company is expressly not providing revenue guidance beyond the current quarter. Please further note that the outlook excludes items which will be required by GAAP, such as restructuring and other charges associated with the Global Realignment Program, amortization of purchased intangibles, reductions of goodwill and other long-lived assets, stock-based compensation expense, and gains and losses on investments. We are unable to provide comparable guidance prepared in accordance with GAAP because the likelihood and amount of these items are uncertain at this time.

Conference Call

The Company will discuss these results and other related matters at 1:30 p.m. Pacific Time on October 23, 2003 in a live webcast, which will also be archived for replay on the Company's website at www.jdsu.com under Investor Relations / Investor Presentations and on the Investor Relations Welcome Page. This press release is being filed as a Current Report on Form 8-K with the Securities and Exchange Commission, and will be available at www.sec.gov shortly after it becomes public.
