Brocade Reports Fiscal Q1 2013 Results

Achieves Record Revenue and Expanding Margins in First Quarter

SAN JOSE, Calif., February 14, 2013 — Brocade^® (NASDAQ: BRCD) today reported financial results for its first fiscal quarter ended January 26, 2013. Brocade reported record first quarter revenue of $588.7 million, representing an increase of 5% year-over-year and 2% quarter-over-quarter. The company reported a GAAP loss per share of $(0.05), down from a profit of $0.12 per diluted share in Q1 2012. The Q1 2013 net loss was principally due to a non-cash tax charge, which reduced the company's deferred tax assets as a result of a recent change in the California tax code. On a comparative basis, non-GAAP diluted EPS was $0.21, up from $0.20 in Q1 2012.

“Brocade achieved record revenue in Q1 based on strong performances in both our storage and IP networking businesses,” said Lloyd Carney, CEO of Brocade. “As the new CEO, it is my top priority to ensure that the company continues to execute well in our core businesses to drive growth and shareholder value. Looking forward, I see new opportunities emerging in the networking industry due to disruptive IT market trends that are challenging the capabilities of today's networks. It is clear that customers are looking for new technologies and approaches in networking to meet these challenges. I am excited and honored to navigate the company forward, delivering on these customer requirements in a way that drives top-line revenue through both innovation and operational efficiency.”

Summary of Q1 2013 results:

• Storage Area Networking (SAN) business revenue, including products and services, was a record $416.9 million, up 3% year-over-year and up 6% sequentially. SAN product revenue increased 3% year-over-year and increased 7% sequentially, led by higher switch and director product sales, in a seasonally strong quarter for the company. Brocade's industry-leading Gen 5 (16 Gbps) Fibre Channel products represented approximately 42% of director and switch revenue in the quarter.

• IP Networking business revenue, including products and services, was $171.8 million, up 11% year-over-year and down 7% quarter-over-quarter. The year-over-year growth was driven by solid performances across all three IP Networking product groups and led by Ethernet switch revenue, which was up 18% year-over-year. Routing revenue was up 5% year-over-year and other IP Networking revenue was up 25% year-over-year driven by higher sales of the Brocade ADX^® Series of application delivery products. The sequential decline in IP Networking revenue was principally due to lower Ethernet switch sales into the U.S. federal government, which is typical in the company's first fiscal quarter.

• GAAP gross margin was 63.5% and non-GAAP gross margin was 66.0% in Q1 2013, compared to 61.5% and 64.8% in Q1 2012, respectively. The year-over-year improvement in gross margin was due in part to higher overall revenue and a more favorable Ethernet product mix. The sequential improvement in gross margin was due in part to higher overall revenue, with a more favorable revenue mix to SAN products, and lower manufacturing overhead spending.

• GAAP operating margin was 15.8% and non-GAAP operating margin was 23.5% in Q1 2013, compared to 12.4% and 21.5% in Q1 2012, respectively. The year-over-year improvement in operating margin was due to higher revenue, expanded gross margin, and lower operating expenses as a percentage of revenue in Q1 2013. Operating margin improved quarter-over-quarter due to higher revenue and improved gross margin.

• Operating cash flow was $59.5 million in Q1 2013. During the quarter, the company completed its acquisition of Vyatta, Inc. and refinanced $300.0 million of senior secured notes, extending the maturity date of the notes from 2018 to 2023 and reducing the annual cash interest rate from 6.625% to 4.625%.

• GAAP loss per share was $(0.05) in Q1 2013, and non-GAAP diluted EPS of $0.21 was up 7% year-over-year. The GAAP loss per share included a non-cash tax charge of $78.2 million, or $(0.17) per share, due to the passage of Proposition 39 by the voters of California and the related reduction in the company's deferred tax assets, which was previously disclosed in November 2012. The company also took a one-time charge of $15.3 million, or $(0.02) per share after tax impact, related to the unamortized original issuance costs and call premium on the 2018 notes that were refinanced during the quarter.

• Average diluted shares outstanding for Q1 2013 were 466.3 million shares, down slightly year-over-year. The company repurchased 8.7 million shares ($47.5 million) during Q1 2013.

Brocade management will host a conference call to discuss fiscal first quarter results and fiscal second quarter outlook today at 2:00 p.m. PT (5:00 p.m. ET).

Non-GAAP Financial Measures

This press release contains non-GAAP financial measures. In evaluating Brocade's performance, management uses certain non-GAAP financial measures to supplement consolidated financial statements prepared under GAAP.

Management believes that non-GAAP financial measures used in this press release allow management to gain a better understanding of Brocade's comparative operating performance both from period to period, and to its competitors' operating results. Management also believes these non-GAAP financial measures help indicate Brocade's baseline performance before gains, losses or charges that are considered by management to be outside ongoing operating results. Accordingly, management uses these non-GAAP financial 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 financial measures, when read in conjunction with Brocade's GAAP financials, provide useful information to investors by offering:

• the ability to make more meaningful period-to-period comparisons of Brocade's ongoing operating results;

• the ability to make more meaningful comparisons of Brocade's operating performance against industry and competitor companies;

• the ability to better identify trends in Brocade's underlying business and to perform related trend analysis;

• a better understanding of how management plans and measures Brocade's underlying business; and

• an easier way to compare Brocade'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 Brocade's continuing operations. Management believes that it is appropriate to evaluate Brocade's operating performance by excluding those items that are not indicative of ongoing operating results or limit comparability. Such items include: (i) provision or benefit from certain pre-acquisition litigation (ii) legal fees associated with certain pre-acquisition litigation, (iii) legal fees associated with indemnification obligations and other related costs, net, (iv) acquisition and integration costs, (v) loss on sale of property, (vi) interest expense related to the adoption of new standards relating to convertible debt instruments, (vii) original issue discount and debt issuance costs of debt related to lenders that did not participate in refinancing as well as debt call premium cost, (viii) loss on sale of a subsidiary, and (ix) specific non-cash and non-recurring tax benefits or detriments.

Management also excludes the following non-cash charges in determining non-GAAP net income (i) stock-based compensation expense 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. 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 Brocade'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 of non-GAAP net income.

Limitations These non-GAAP financial 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 Brocade's GAAP results. The non-GAAP financial measures that Brocade 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 net income per share, and should not be considered measurements of Brocade'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 measurements reported by other companies.
