Sonus Networks Releases Third Quarter 2017 Financial Results

WESTFORD, Mass., Oct. 30, 2017 /PRNewswire/ -- Sonus Networks, Inc. (Nasdaq: SONS), a global leader in secure and intelligent cloud communications, today announced results for Sonus and GENBAND for the third quarter ended September 30, 2017.

"Sonus' third quarter results were highlighted by 14.8% year-over-year revenue growth and non-GAAP gross margin of 75.6%. We are very pleased on delivering major milestones for the large competitive displacement for a North American Tier 1 carrier. These achievements demonstrate our evolution to software solutions and the result of many years of investment in network virtualization," said Raymond Dolan, president and chief executive officer.

Mr. Dolan continued, "We have completed extensive Sonus and GENBAND integration planning with significant first day integration execution underway and remain committed to attaining the $40 million to $50 million of annual cost savings anticipated when we announced our plans this past May. As a combined company, our product offerings are even more strategic to customers, and our scale will allow us to invest even more in key areas as both service providers and enterprises migrate to fully-virtualized, cloud architectures."

    1) Projections are post close from 10/30/2017 to 12/31/2017 for GENBAND.

    2) Flat from FY'16 revenue for Sonus of $252.6M.

    3) Revenue does not include impact of purchase accounting reductions, which are expected to be completed in Q4'17.

    4) Share count increased from prior projections due to ~51M shares issued on 10/30/2017 related to the Sonus/GENBAND merger.

We are unable to provide a reconciliation of the forward-looking non-GAAP measures presented above to the most directly comparable GAAP measures without unreasonable efforts due to our inability at this time to estimate the amount and timing of charges (including acquisition-related, restructuring, merger integration and stock-based compensation expenses) to be incurred during the remainder of the year as a result of the Sonus/GENBAND merger, which was completed on October 27, 2017. We are also unable at this time to estimate the impact of purchase accounting reductions affecting GENBAND revenues.

Discussion of Non-GAAP Financial Measures
Sonus management uses several different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of the business, making operating decisions, planning and forecasting future periods, and determining payments under compensation programs. Our annual financial plan is prepared both on a GAAP and non-GAAP basis, and the non-GAAP annual financial plan is approved by our board of directors. Continuous budgeting and forecasting for revenue and expenses are conducted on a non-GAAP basis (in addition to GAAP) and actual results on a non-GAAP basis are assessed against the annual financial plan. We consider the use of non-GAAP financial measures helpful in assessing the core performance of our continuing operations and liquidity, and when planning and forecasting future periods. By continuing operations, we mean the ongoing results of the business excluding certain expenses and credits, including, but not limited to: stock-based compensation, amortization of intangible assets, merger integration costs, settlement expense, acquisition-related expense, restructuring and certain gains included in other income (expense). While our management uses non-GAAP financial measures as a tool to enhance their understanding of certain aspects of our financial performance, our management does not consider these measures to be a substitute for, or superior to, GAAP measures. In addition, our presentations of these measures may not be comparable to similarly titled measures used by other companies. These non-GAAP financial measures should not be considered alternatives for, or in isolation from, the financial information prepared and presented in accordance with GAAP.

Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to Sonus' financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future.

Stock-based compensation is different from other forms of compensation, as it is a non-cash expense. For example, a cash salary generally has a fixed and unvarying cash cost. In contrast, the expense associated with an equity-based award is generally unrelated to the amount of cash ultimately received by the employee, and the cost to us is based on a stock-based compensation valuation methodology and underlying assumptions that may vary over time. We believe that excluding non-cash stock-based compensation expense from our operating results facilitates the comparison of our financial statements to our historical operating results and to other companies in our industry.

We exclude the amortization of acquired intangible assets from non-GAAP expense and income measures. These amortization amounts are inconsistent in frequency and amount and are significantly impacted by the timing and size of acquisitions. Although we exclude amortization of acquired intangible assets from our non-GAAP expenses, we believe that it is important for investors to understand that intangible assets contribute to revenue generation. We believe that excluding the non-cash amortization of intangible assets facilitates the comparison of our financial results to our historical operating results and to other companies in our industry as if the acquired intangible assets had been developed internally rather than acquired.

We consider certain merger integration costs to be unpredictable and dependent a significant number of factors that may be outside of our control. We do not consider these merger integration costs to be related to the continuing operations of the combined business or the Company. In addition, the size, complexity and/or volume of an acquisition, which often drives the magnitude of merger integration costs, may not be indicative of such future costs. We believe that excluding merger integration costs facilitates the comparison of our financial results to our historical operating results and to other companies in our industry.

In September 2017, we recorded $1.6 million of expense related to potential fines in connection with the ongoing SEC investigation. In June 2016, we recorded $0.6 million of patent litigation settlement costs. This amount is included as a component of General and administrative expense; however, we believe that such patent litigation settlement costs are not part of our core business or ongoing operations. Accordingly, we believe that excluding this patent litigation settlement expense facilitates the comparison of our financial results to our historical operating results and to other companies in our industry.

We consider certain acquisition-related costs to be unpredictable and dependent on a significant number of factors that may be outside of our control. We do not consider these acquisition-related costs to be related to the continuing operations of the acquired business or the Company. In addition, the size, complexity and/or volume of an acquisition, which often drives the magnitude of acquisition-related costs, may not be indicative of such future costs. We believe that excluding acquisition-related costs facilitates the comparison of our financial results to our historical operating results and to other companies in our industry.

We have recorded restructuring expense to streamline operations and reduce operating costs by closing and consolidating certain facilities and reducing our worldwide workforce. We review our restructuring accruals regularly and record adjustments (both expense and credits) to these estimates as required. We believe that excluding restructuring expense and credits facilitates the comparison of our financial results to our historical operating results and to other companies in our industry, as there are no future revenue streams or other benefits associated with these costs.

In May 2017, we sold a block of IP addresses that we had acquired in connection with our acquisition of Network Equipment Technologies, Inc. ("NET") and recognized a gain, net of commission and fees, of $0.6 million. In July 2016, we sold the NET domain name to a third party and recognized a gain, net of commission and fees, of $0.8 million. These amounts are included as components of Other income, net, in the respective periods. We believe that such gains are not part of our core business or ongoing operations. Accordingly, we believe that excluding the other income arising from these sales facilitates the comparison of our financial results to our historical results and to other companies in our industry.

We believe that providing non-GAAP information to investors, in addition to the GAAP presentation, will allow investors to view the financial results in the way management views the operating results. We further believe that providing this information helps investors to better understand our financial performance and evaluate the efficacy of the methodology and information used by our management to evaluate and measure such performance.
