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:

• Revenue $252.7 million, up 9% year-over-year and up 5% quarter-over-quarter.

• GAAP gross margin 55.9% compared to 55.8%, in Q2 last year.

• Non-GAAP gross margin 58.2% compared to 59.4%, in Q2 last year.  

• GAAP operating margin 1.9% compared to (13.5)%, in Q2 last year.

• Non-GAAP operating margin 8.0%, compared to 8.8%, in Q2 last year.

• Free Cash Flow* $23.6 million before share buyback and $8.6 million after share buyback.

“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.”

Recent Key Highlights:

• University of Central Arkansas required a strong, secure network infrastructure to fully support plans for its Arkansas Coding Academy and to achieve their goal of being a “Technology First

University”. The university selected Extreme Automated Campus™ solutions, including Extreme Fabric Connect™ and Extreme Cloud Appliance, to implement a complete networking solution for their campus of 124 buildings, spread across 356 acres, populated by 11,350 students and 16 NCAA Division I varsity teams. Extreme management, control and analytics software have streamlined network management for the UCA IT team, eliminating strain and the potential for errors.

• The City of Memphis (Tennessee), the 22nd largest US city by land area and with over 8,000 city employees, selected Extreme’s switching, management and analytics technology, part of its Automated Campus™ solution, as well as Extreme Professional Services, to power its new Smart City infrastructure. Initial deployments will enable AI-powered IP camera implementations at 27 community centers to provide real-time anomaly detection and will eventually extend to other parts of the community, including police, fire and highway departments as the city continues its digital transformation. The City valued Extreme’s Fabric Connect™ technology, which allows for network segmentation for secure user and device access.

• University of Pittsburgh Athletics Department, part of the ACC Conference, deployed Extreme’s Smart OmniEdge™ solutions to provide wireless connectivity in its 12,000-seat arena that hosts men's and women's basketball and volleyball, along with concerts and other events.

For its third quarter of fiscal 2019, ending March 31, 2019, the Company is targeting revenue in a range of $247.0 million to $257.0 million.  GAAP gross margin is targeted between 55.2% and 57.3% and non-GAAP gross margin is targeted between 57.5% and 59.5%. Operating expenses are targeted to be between $139.7 million and $143.0 million on a GAAP basis and $129.9 million to $133.2 million on a non-GAAP basis.

Extreme Networks, Inc.

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.
