Financial Results

     Second quarter revenues, essentially all of which were comprised of Fibre Channel products, rose 25% sequentially from the first fiscal quarter to $91.7 million. Second quarter non-GAAP net income declined by 9% from the comparable year-ago results, but nearly doubled sequentially to $18.9 million, or $0.21 per diluted share, reflecting margin improvement achieved on sequentially flat operating expenses coupled with higher than originally expected sequential revenue growth. Second quarter GAAP net income, including charges associated with previous acquisitions, was sequentially flat but nearly tripled from a year ago to $14.2 million, or $0.16 per diluted share. A reconciliation between GAAP and non-GAAP results is included in the accompanying financial data.

     Paul Folino, Emulex Chairman and CEO, stated, “The 25% sequential growth in customer demand for Emulex solutions was twice the original guidance level, as orders surged across our customer base and both InSpeed and LightPulse product families. Our mix of switching product revenue to HBAs remained relatively unchanged from the first quarter, reflecting solid sequential gains across both HBA and switching product lines. As we exited the December quarter, channel inventories dropped sequentially, indicating that once again actual point-of-sale channel demand for Emulex HBAs had outpaced recorded revenue.” Emulex’s InSpeed storage switching solutions continued to gain momentum in the market as the company expanded its installed base to 4 million ports, complementing its installed base of 1.8 million Emulex HBAs.

     Folino continued, “As part of our ongoing growth and diversification strategy, we plan to expand our engineering, sales and marketing investment in upcoming quarters as we introduce new Emulex Fibre Channel connectivity solutions for the blade server and volume server markets, enter new multi-protocol storage markets, and launch support for newly acquired OEM customers.” Recently, Emulex introduced its first HBA designed for the IBM eServer BladeCenter, the market’s leading blade server system, which will commence commercial shipment in the current quarter. Folino concluded, “To fuel growth, Emulex is launching more new products this fiscal year than ever before, including a complete line of 4 gigabit per second Fibre Channel I/O and switching products which are rapidly gaining a first-to-market leadership position among our OEMs. Soon, these will be complemented by jointly developed multi-protocol ASICs arising from our strategic relationship with Intel that will offer OEMs an unprecedented, universal serial storage solution spanning Fibre Channel, Serial Attached SCSI and Serial ATA protocols. With interest in 4 gigabit and multi-protocol

technologies accelerating, Emulex is committed to maximizing the new market opportunities ahead of us.”

Business Outlook

     Although actual results may vary depending on a variety of factors, many of which are outside Emulex’s control, Emulex is providing guidance for its third fiscal quarter ending March 2005. Emulex is budgeting for third quarter revenue in a range of $91-93 million, gross margins at 63%, and non-GAAP earnings per share of $0.18-$0.20. On a GAAP basis, Emulex expects diluted third quarter EPS of $0.13-$0.15 per share, reflecting approximately $0.05 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 subsequent benefits related to an inventory charge, impairment charges, gains or losses on the repurchase of convertible subordinated notes and litigation settlements, as well as charges relating to the amortization of deferred 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. 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, natural disasters 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, lowest cost product platforms; possible transitions from board level to application specific computer chip solutions for selected applications; a shift in unit product mix from higher-end to lower-end 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; the effect of acquisitions; impairment charges; and changes in tax rates or changes in accounting standards, including changes in the accounting treatment of employee stock options and contingent convertible debt. 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 these previously impaired products is excluded.

⁽²⁾Impairment of goodwill. During the first quarter of fiscal 2005, the Company changed estimates and discovered errors related to the deferred tax assets of Vixel Corporation (acquired in November 2004). As a result, the Company recorded a $1.8 million impairment of goodwill in the first quarter of fiscal 2005. Had these items been recorded in fiscal 2004, the Company’s net loss would have been $1.8 million higher, or $534.1 million, instead of $532.3 million. The Company does not believe that this $1.8 million impairment of goodwill is material to fiscal 2004 or 2005 operations.

⁽³⁾Net loss (gain) on repurchase of convertible subordinated notes. In the three months ended September 26, 2004, Emulex repurchased $153.0 million in face value of its 0.25% convertible subordinated notes at a discount, resulting in a pre-tax gain of $13.1 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. Additionally, in the three months ended September 28, 2003, Emulex repurchased $93.9 million in face value of its 1.75% convertible subordinated notes at a discount, resulting in a pre-tax gain of $4.7 million.
