Brocade Reports Second Quarter Fiscal Year 2007 Results

Revenues Reported of $345.3 Million

SAN JOSE, Calif. — May 31, 2007— Brocade® (Nasdaq: BRCD), the leader in networked storage solutions that help enterprises connect and manage their information, today reported financial results for its second quarter of fiscal year 2007 (Q2 07), which ended April 28, 2007. Revenues for Q2 07 were $345.3 million. Revenues for Q2 07 increased 54% from $224.2 million reported in the first quarter of fiscal year 2007 (Q1 07) and increased 89% from $182.7 million reported in the second quarter of fiscal year 2006 (Q2 06). Q2 07 results include products and services acquired through the McDATA transaction which closed on January 29, 2007.

Commenting on the Company’s second quarter results, CEO Michael Klayko said, “The fundamentals of our business remain strong and I am extremely pleased with our execution this quarter. We will continue to execute on our strategy of growth and diversification and we remain committed to delivering exceptional results.”

Reporting on a GAAP basis, net income for Q2 07 was $0.8 million, or $0.00 per share basic and diluted. This reflects a decrease in GAAP net income of 98% from $33.3 million, or $0.12 per share basic and diluted in Q1 07, and a decrease of 94% from GAAP net income of $13.5 million, or $0.05 per share basic and diluted in Q2 06. The decrease quarter to quarter reflects the impact of non-cash amortization of purchased intangibles and related income tax adjustments from the McDATA acquisition.

Non-GAAP net income for Q2 07 was $46.6 million or $0.12 per share basic and $0.11 per share diluted. This reflects a decrease of 6% from non-GAAP net income of $49.4 million, or $0.18 per share basic and $0.17 per share diluted in Q1 07, and an increase of 77% from non-GAAP net income of $26.4 million, or $0.10 per share basic and diluted in Q2 06. Non-GAAP financial measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. A detailed reconciliation between GAAP and non-GAAP information is contained in the tables included herein.

·	In Q2 07, as a percent of total, service revenue exceeded 10% for the first time.

In Q2 07, as a percent of total, OEM revenues were 85% and Channel/Direct were 15%. This compares to 92% and 8%, respectively in Q1 07 and 93% and 7%, respectively, in Q2 06. Three OEM customers, EMC, HP, and IBM, each accounted for 10% or more of total revenues and together represented approximately 67% of total revenues. The same three customers each accounted for 10% or more of total revenues and together represented approximately 72% in Q1 07 and 70% in Q2 06 of total revenues.

·	In Q2 07, as a percent of total, domestic revenue was 65% and international was 35%. This compares to 59% and 41%, respectively in Q1 07 and 63% and 37%, respectively, in Q2 06.

·	Q2 07 port growth was 63% from Q1 07, reflecting the addition of McDATA product offerings. This brings the Company’s total installed base to approximately 13.2 million installed SAN ports.

·	Q2 07 sequential Average Selling Price (ASP) declines were again in the low single digits.

·	Q2 07 non-GAAP operating margin was 16.8%, compared to non-GAAP operating margin of 26.1% in Q1 07 and non-GAAP operating margin of 16.6% in Q2 06.

·	As of April 28, 2007, the Company had 2,440 employees, compared with 1,532 employees as of January 27, 2007 and 1,316 employees as of April 29, 2006. The increase in employees reflects the acquisition of McDATA Corporation, which closed during Q2 07.

·	Q2 07 results include a full quarter of McDATA results. Prior periods do not include McDATA results.

In Q2 07, the Company executed exceptionally well on its McDATA integration plan.

Finally, on a non-GAAP basis, the Company achieved its target operating margin model of 15-20%.

Non-GAAP Financial Measures

This press release and the related conference call contain non-GAAP financial measures. In evaluating the Company’s performance, management uses certain non-GAAP financial measures to supplement consolidated financial statements prepared under GAAP.

Management believes that the non-GAAP net income measure used in this press release allows management to gain a better understanding of the Company’s comparative operating performance from period-to-period and to its competitors’ operating results. Management also believes these non-GAAP measures help indicate the Company baseline performance before gains, losses or charges that are considered by management to be outside on-going operating results. Accordingly, management uses these non-GAAP measures for planning and forecasting of future periods and in making decisions regarding operations performance and the allocation of resources. Management believes these non-GAAP earnings measures, when read in conjunction with the Company’s GAAP financials, provide useful information to investors by offering:

PAGE 4 OF 11

BROCADE REPORTS SECOND QUARTER FISCAL 2007 FINANCIAL RESULTS

PAGE 5

·	the ability to make more meaningful period-to-period comparisons of the Company’s on-going operating results;

·	the ability to better identify trends in the Company’s underlying business and perform related trend analysis;

·	a better understanding of how management plans and measures the Company’s underlying business; and

·	an easier way to compare the Company’s most recent results of operations against investor and analyst financial models.

Management excludes certain gains or losses and benefits or costs in determining non-GAAP net income that are the result of infrequent events, or arise outside the ordinary course of our continuing operations. Management believes that it is appropriate to evaluate the Company’s operating performance by excluding those items that are not indicative of ongoing operating results or limit comparability. Such items include: (i) acquisition and integration costs, (ii) facilities lease losses and (iii) legal fees associated with indemnification obligations to former employees and other related costs.

Management also excludes the following non-cash charges in determining non-GAAP net income: (i) stock-based compensation and (ii) amortization of purchased intangible assets. Because of varying available valuation methodologies, subjective assumptions and the variety of award types, management believes that the exclusion of stock-based compensation allows for more accurate comparisons of our operating results to our peer companies. Further, management believes that excluding stock-based compensation expense allows for a more accurate comparison of our financial results to previous periods during which our equity-based awards were not required to be reflected on our income statement. Management believes that the expense associated with the amortization of acquisition-related intangible assets is appropriate to be excluded because a significant portion of the purchase price for acquisitions may be allocated to intangible assets that have short lives and exclusion of the amortization expense allows comparisons of operating results that are consistent over time for both the Company’s newly acquired and long-held businesses.

Finally, management believes that it is appropriate to exclude the tax effects of the items noted above in order to present a more meaningful measure on non-GAAP net income.

Limitations. These non-GAAP measures have limitations, however, because they do not include all items of income and expense that impact the Company. Management compensates for these limitations by also considering the Company’s GAAP results. The non-GAAP financial measures the Company uses are not prepared in accordance with, and should not be considered an alternative to, measurements required by GAAP, such as operating income, net income and income per share, and should not be considered measures of the Company’s liquidity. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the most directly comparable GAAP measures. In addition, these non-GAAP financial measures may not be comparable to similar measures reported by other companies.
