Management Comment

“Our profitable third quarter was led by a healthy rebound in our Internet-of-Things revenue on top of our seasonally strong Smart TV business, strong gross margin performance, and lower operating expenses,” said Thinh Tran, President and CEO of Sigma Designs, Inc. “We remain encouraged by our outlook for the Internet-of-Things business, which should continue to grow as consumer adoption of Z-Wave enabled products improves. For the long-term, we expect to capitalize on the multitude of new opportunities across our business to drive revenue, and combine this execution with cost reductions, in order to deliver stronger earnings.”

Use of Non-GAAP Financial Information 

In addition to reporting financial results in accordance with generally accepted accounting principles (“GAAP”), Sigma reports non-GAAP net income (loss), as Sigma believes that evaluating its ongoing operating results may be difficult if limited to reviewing only GAAP financial measures. Accordingly, non-GAAP financial measures  exclude amortization of acquired intangibles, stock-based compensation, one-time legal fee expenses, net gain on sale of and impairment of privately-held investments, impairment of purchased IP, mask sets and design tools used in production, the reversal of previously accrued rebates and the one-time gain from the gain on sale of development project. The tax amounts included in Sigma’s non-GAAP results approximate its operating cash tax expense, similar to the liability reported on Sigma’s tax returns. In the GAAP to non-GAAP reconciliation at the end of this press release, we have disclosed the impact of these income tax adjustments in our calculation of our non-GAAP financial results.

Legislative and regulatory requirements encourage the use of and emphasis on GAAP financial metrics and require companies to explain why non-GAAP financial metrics are relevant to management and investors. Sigma believes that its non-GAAP measures provide useful information to management and investors regarding financial and business trends relating to its financial condition and results of operations. Sigma also believes the non-GAAP measures provide useful supplemental information for investors to evaluate its operating results in the same manner as the research analysts that follow Sigma, all of whom present non-GAAP projections in their published reports. As such, the non-GAAP measures provided by Sigma facilitate a more direct comparison of its performance with the financial projections published by the analysts as well as its competitors, many of whom report financial results on a non-GAAP basis. The economic substance behind its decision to use such non-GAAP measures is that such measures approximate its controllable operating performance more closely than the most directly comparable GAAP financial measures. For example, Sigma’s management has no control over certain variables that have a major influence in the determination of stock-based compensation such as the volatility of its stock price and changing interest rates. Sigma believes that all of these excluded expenses may not accurately reflect the underlying performance of its continuing operations for the period in which they are incurred, even though some of these excluded items may be incurred and reflected in Sigma’s GAAP financial results in the foreseeable future. Sigma believes that the inclusion of these non-GAAP financial measures provides consistency and comparability with past reports and provides a better understanding of the overall performance of the business and its ability to perform in subsequent periods.

Non-GAAP financial measures are not a substitute for financial information prepared in accordance with GAAP.  Non-GAAP financial measures should not be considered in isolation, but should be considered together with the most directly comparable GAAP financial measures and the reconciliation of the non-GAAP financial measures to the most directly comparable GAPP financials measures.  The Company presents such non-GAAP financial measures to provide investors with an additional tool to evaluate our operating results in a manner that focuses on what management believes to be its core, ongoing business operations.  

Investors should note that the non-GAAP financial measures used by the Company may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as those of other companies.  Investors should, therefore, exercise caution when comparing non-GAAP financial measures used by us to similarly titled non-GAAP financial measures of other companies. Sigma intends to calculate the various non-GAAP financial measures in future periods consistent with how they were calculated for the periods presented within this press release.
