fiscal quarter, amounting to essentially 100% of third quarter net revenues. Quarterly growth was driven by demand for InSpeed^TM embedded switching solutions, which contributed over 10% of third quarter net revenue. HBA revenues grew from a year ago and declined modestly sequentially in the seasonally soft third quarter. Emulex continued to expand its international business in the third quarter, as sales to Europe and the Pac Rim reached record levels and collectively contributed nearly half of total revenue.

Non-GAAP net income expanded 12% from the comparable year-ago results to $20.9 million, or $0.25 per diluted share. GAAP net income, including charges associated with the Vixel acquisition, amounted to $14.6 million, or $0.17 per diluted share, compared to a net loss of $248,000, or $0.00 per diluted share, for the comparable period last year. A reconciliation between GAAP and non-GAAP results is included in the accompanying financial data.

Paul Folino, Emulex Chairman and CEO, stated, “This quarter showcased the success of the Vixel acquisition and validated our strategy to expand our addressable market through diversification into new growth storage markets, notably embedded storage switching. Revenue from switch products that we acquired with the purchase of Vixel outpaced expectations and drove the third quarter’s sequential and year-to-year growth.” Folino continued, “We are extremely pleased with the successful integration of the Vixel acquisition, which delivered accretive results to non-GAAP earnings in our first full quarter of combined operations.”

With respect to its balance sheet, during the third quarter, the over-allotment option for Emulex’s December convertible note offering was exercised, resulting in the issuance of another $67.5 million in aggregate principal amount of convertible subordinated notes due 2023 with a 0.25% coupon and priced at a 60% conversion premium convertible at $43.20 per share. Additionally, during the third quarter, the Company repurchased $12.3 million in face value of its 1.75% convertible subordinated notes. Emulex exited the third quarter of fiscal 2004 with cash, cash equivalents, restricted cash and investments balances of $630 million.

Business Outlook

Emulex is providing guidance for its fourth fiscal quarter ending June 2004 as follows. Although actual results may vary depending on a variety of factors, many of which are outside Emulex’s control, Emulex is budgeting for year-over-year revenue growth in the 22% to 26% range, and sequential revenue growth of 1% to 4%, with revenue for the quarter in a range of $100 to $103 million and non-GAAP

earnings per share of up to 25 cents. On a GAAP basis, Emulex expects diluted EPS of approximately $0.18 per share, reflecting approximately $0.07 per share in expected GAAP charges arising primarily from amortization of intangibles and deferred stock-based compensation.

Note Regarding Non-GAAP Financial Information. The non-GAAP financial information included in this press release is not prepared in accordance with GAAP as it excludes benefits related to an inventory charge, gains or losses on the repurchase of convertible subordinated notes and litigation settlements, as well as charges relating to the amortization of stock-based compensation and in-process research and development charges. The projected non-GAAP financial information also excludes any acquisition-related charges associated with the acquisitions of Giganet, Vixel and the technology assets of Trebia Networks. Management believes that the presentation of Non-GAAP information may provide useful information to investors because Emulex has historically provided this information and understands that some investors consider it useful in evaluating Emulex’s core business. Management also uses this non-GAAP information, along with the GAAP information, in evaluating Emulex’s business for these purposes. The non-GAAP results should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from non-GAAP or other pro forma measures used by other companies.

“Safe Harbor” Statement under the Private Securities Litigation Reform Act of 1995: With the exception of historical information, the statements set forth above, including, without limitation, those contained in the discussion of “Business Outlook” above, contain forward-looking statements that involve risk and uncertainties. We expressly disclaim any obligation or undertaking to release publicly any updates or changes to these forward-looking statements that may be made to reflect any future events or circumstances. The company wishes to caution readers that a number of important factors could cause actual results to differ materially from those in the forward-looking statements. These factors include risks related to the recent acquisition of Vixel and the fact that the economy generally, and the technology and storage segments specifically, have been in a state of uncertainty making it difficult to determine if past experience is a good guide to the future and making it impossible to determine if markets will grow or shrink in the short term. The Company’s results have been significantly impacted by a widespread slowdown in technology investment that has also pressured the storage networking market that is the mainstay of the Company’s business. A continued downturn in information technology spending could adversely affect the Company’s revenues and results of operations. As a result of this uncertainty, the Company is unable to predict with any accuracy what future results might be. Other factors affecting these forward-looking statements include, but are not limited to, the following: slower than expected growth of the storage networking market or the failure of the Company’s OEM customers to successfully incorporate the Company’s products into their systems; the Company’s dependence on a limited number of customers and the effects of the loss of, or decrease or delays in orders by, any such customers, or the failure of such customers to make payments; the emergence of new or stronger competitors as a result of consolidation movements in the market; the timing and market acceptance of the Company’s or the Company’s OEM customers’ new or enhanced products; the variability in the level of the Company’s backlog and the variable booking patterns of the Company’s customers; the effects of terrorist activities and resulting political or economic instability; the highly competitive nature of the markets for the Company’s products as well as pricing pressures that may result from such competitive conditions; the Company’s ability and the ability of the Company’s OEM customers to keep pace with the rapid technological changes in the Company’s industry and gain market acceptance for new products and technologies; the effect of rapid migration of customers towards newer product platforms; possible transitions from board level to application specific computer chip solutions for selected applications; a shift in unit product mix from high-end to midrange products; a decrease in the average unit selling prices or an increase in the manufactured cost of the Company’s products; delays in product development; the Company’s reliance on third-party suppliers and subcontractors for components and assembly; any inadequacy of the Company’s intellectual property protection or the potential for third-party claims of infringement; the Company’s ability to attract and retain key technical personnel; the Company’s dependence on foreign sales; and the effect of acquisitions, changes in tax rates or changes in accounting standards. These and other factors which could cause actual results to differ materially from those in the forward-looking statements are discussed in the company’s filings with the Securities and Exchange Commission, including its recent filings on Forms 8-K, 10-K and 10-Q, under the caption “Risk Factors.”

This news release refers to various products and companies by their trade names. In most, if not all, cases these designations are claimed as trademarks or registered trademarks by their respective companies.

¹ Excess and obsolete inventory charge. Starting in late September 2001, some of Emulex’s major customers made announcements that general economic conditions, exacerbated by the increase in economic uncertainty in the aftermath of the terrorist events of September 11, 2001, were having a negative impact on their financial results. The announcements made, and forecasts received, indicated deteriorating demand for the Company’s one gigabit per second (Gbps) products as these customers were expected to migrate to two Gbps products for future purchases. In order to provide meaningful comparisons of operating results, any subsequent consumption of previously impaired products is excluded.

² Gain/loss on repurchase of convertible subordinated notes. In the three months ended March 28, 2003, Emulex repurchased $12.3 million in face value of its convertible subordinated notes, resulting in a pre-tax loss of $0.2 million. In the three months ended December 28, 2003, Emulex repurchased $85.4 million in face value of its 1.75% convertible subordinated notes, resulting in a pre-tax loss of $1.8 million. In the three months ended September 28, 2003, Emulex repurchased $93.9 million in face value of its convertible subordinated notes at a 7% discount, resulting in a pre-tax gain of $4.7 million. In the three months ended September 29, 2002, Emulex repurchased $136 million in face value of its convertible subordinated notes at a 24% discount, resulting in a pre-tax gain of $28.7 million.
