Extreme Networks Reports Second Quarter Fiscal Year 2019 Financial Results

SAN JOSE, Calif., January 29, 2019 -- Extreme Networks, Inc. (“Extreme”) (Nasdaq: EXTR) today released financial results for its fiscal second quarter ended December 31, 2018.

Fiscal Second Quarter Results:  

“We are pleased to report revenue above the high-end of our guidance range and demonstrate sequential growth. Our results were driven by cross-selling and the adoption of our Smart OmniEdge, Automated Campus, and Agile Data Center solutions pillars that make up our end to end software-driven solutions across geographies and industry verticals.  We also saw a modest increase in demand during the quarter as a result of our November 1^st price increase. Separately, we reaffirmed our commitment to accretive use of our cash by completing $15 million worth of our share repurchase program during the quarter,” stated Ed Meyercord, President and CEO of Extreme Networks.

Executive Vice President and CFO Rémi Thomas added, “We are reaffirming our outlook for FY19 to exceed $1 billion in revenue. Following the strong cash flow resulting from exceptional linearity during the quarter and some forward buying that drove outperformance of our second quarter results, we expect our revenue and gross margin for the third quarter to be comparable to our second quarter results. We continue to target improving our net cash position throughout the fiscal year and are in a solid position for growth and continued long-term gross margin improvement.”

Meyercord concluded, “Looking ahead, our strong roadmap and improved execution, combined with the digital transformation initiatives we are undertaking internally, will enable us to drive productivity and operational efficiencies in the second half of our fiscal year. We look forward to an in-depth review of our vision, strategy and operating initiatives at our Investor Day conference on February 13, 2019.”

Non-GAAP Financial Measures:

Extreme provides all financial information required in accordance with generally accepted accounting principles (“GAAP”). The Company is providing with this press release non-GAAP gross margins, non-GAAP operating margins, non-GAAP operating expenses, non-GAAP net income and non-GAAP earnings per share. In preparing non-GAAP information, the Company has excluded, where applicable, the impact of share-based compensation, acquisition and integration costs, acquired inventory adjustments, amortization of acquired intangibles, restructuring charges, gain on sale of equity investment and income tax.  The Company believes that excluding these items provides both management and investors with additional insight into its current operations, the trends affecting the Company, the Company's marketplace performance, and the Company's ability to generate cash from operations. Please note the Company's non-GAAP measures may be different than those used by other companies. The additional non-GAAP financial information the Company presents should be considered in conjunction with, and not as a substitute for, the Company's GAAP financial information.  

The Company has provided a non-GAAP reconciliation of the results for the periods presented in this release, which are adjusted to exclude certain items as indicated.  These measures should only be used to evaluate the Company's results of operations in conjunction with the corresponding GAAP measures for comparable financial information and understanding of the Company's ongoing performance as a business. Extreme Networks uses both GAAP and non-GAAP measures to evaluate and manage its operations.

Forward Looking Statements:

Statements in this release, including those concerning the Company’s business outlook, future financial and operating results, acquired technologies and operations, future price increases, changes to our supply chain, the introduction of new products, the impact of tariffs on our products, including the relocation of certain manufacturing activities outside of China in the future, the success of our digital transformation initiatives, and overall future prospects are forward-looking statements within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements speak only as of the date of this release. Actual results or events could differ materially from those anticipated in those forward-looking statements as a result of certain factors, including: our failure

to achieve targeted revenues and forecasted demand from end customers; a highly competitive business environment for network switching equipment; our effectiveness in controlling expenses; the possibility that we might experience delays in the development or introduction of new technology and products; customer response to our new technology and products; risks related to pending or future litigation; and a dependency on third parties for certain components and for the manufacturing of our products.  

More information about potential factors that could affect the Company's business and financial results are described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Risk Factors" included in the Company’s Quarterly Report on Form 10-Q for the three months ended September 30, 2018 and Annual Report on Form 10-K for the year ended June 30, 2018 and other documents of the Company on file with the Securities and Exchange Commission (available at www.sec.gov).  Except as required under the U.S. federal securities laws and the rules and regulations of the U.S. Securities and Exchange Commission, Extreme Networks disclaims any obligation to update any forward-looking statements after the date of this release, whether as a result of new information, future events, developments, changes in assumptions or otherwise.

Non-GAAP Measures of Financial Performance

To supplement the Company's consolidated financial statements presented in accordance with generally accepted accounting principles, ("GAAP"), Extreme Networks uses non-GAAP measures of certain components of financial performance.  These non-GAAP measures include non-GAAP net income, non-GAAP earnings per diluted share, non-GAAP gross margin, non-GAAP operating expenses and free cash flow.

Reconciliation to the nearest GAAP measure of all historical non-GAAP measures included in this press release can be found in the tables included with this press release.  In this press release, Extreme Networks also presents its target for non-GAAP expenses, which is expenses less share-based compensation expense, acquisition and integration costs, acquired inventory adjustments, restructuring charges, amortization of acquired intangibles, gain on sale of equity investment and income tax.

Non-GAAP measures presented in this press release are not in accordance with or alternative measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies.  In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles.  Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Extreme Networks' results of operations as determined in accordance with GAAP.  These non-GAAP measures should only be used to evaluate Extreme Networks' results of operations in conjunction with the corresponding GAAP measures.

Extreme believes these non-GAAP measures when shown in conjunction with the corresponding GAAP measures to enhance investors' and management's overall understanding of the Company's current financial performance and the Company's prospects for the future, including cash flows available to pursue opportunities to enhance shareholder value.  In addition, because Extreme Networks has historically reported certain non-GAAP results to investors, the Company believes the inclusion of non-GAAP measures provides consistency in the Company's financial reporting.

For its internal planning process, and as discussed further below, Extreme's management uses financial statements that do not include share-based compensation expense, acquisition and integration costs, acquired inventory adjustment, amortization of intangibles, restructuring charges, gain on sale of equity investment and income tax.  Extreme’s management also uses non-GAAP measures, in addition to the corresponding GAAP measures, in reviewing the Company's financial results.

As described above, Extreme excludes the following items from one or more of its non-GAAP measures when applicable.

Share-based compensation. This expense consists of expenses for stock options, restricted stock and employee stock purchases through its ESPP.  Extreme Networks excludes share-based compensation expenses from its non-GAAP measures primarily because they are non-cash expenses that the Company does not believe are reflective of ongoing cash requirement related to operating results. Extreme Networks expects to incur share-based compensation expenses in future periods.

Acquisition and integration costs. Acquisition and integration costs consist of legal and professional fees related to the acquisition of a) Campus Fabric business, b) Data Center business and c) the bargain

purchase gain for the capital financing business; Extreme Networks excludes these expenses since they result from an event that is outside the ordinary course of continuing operations.

Acquired inventory adjustments.   Purchase accounting adjustments relating to the mark up of acquired inventory to fair value less disposal costs.

Amortization of acquired intangibles.  Amortization of acquired intangibles includes the monthly amortization expense of acquired intangible assets such as developed technology, customer relationships, trademarks and order backlog.  The amortization of the developed technology intangible is recorded in product cost of goods sold, while the amortization for the other intangibles are recorded in operating expenses.  Extreme Networks excludes these non-cash expenses since they result from an intangible asset and for which the period expense does not impact the operations of the business and are non-cash in nature.

Restructuring expenses. Restructuring expenses primarily consist of severance costs for employees which have no benefit to continuing operations and accrued lease costs pertaining to the estimated future obligations for non-cancelable lease payments related to excess facilities. Extreme Networks excludes restructuring expenses since they result from events that often occur outside of the ordinary course of continuing operations.

Gain on sale of equity investment.  The gain on the sale of an equity investment refers to a third party acquisition that acquired a business entity in which the Company had an equity investment.

Income tax.   Income tax adjustments relate to the tax impact of reducing the US tax rate applied to deferred tax items pursuant to the recently enacted US tax legislation, the tax benefit resulting from the impairment of a lease acquired from Avaya in Canada and the impact of our Australian valuation allowance.

In addition to the non-GAAP measures discussed above, Extreme uses free cash flow as a measure of operating performance.  Free cash flow represents operating cash flows less net purchase of property and equipment on a GAAP basis.  Extreme considers free cash flows to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business after the purchases of property and equipment, which can then be used to, among other things, invest in Extreme’s business, make strategic acquisitions, and strengthen the balance sheet.  A limitation of the utility of free cash flows as a measure of financial performance is that it does not represent the total increase or decrease in the Company's cash balance for the period.
