Management Comment

“Consistent with the guidance we provided in our last earnings call, we are reporting $51.5 million in revenue for the fourth quarter,” said Thinh Tran, President and CEO of Sigma Designs, Inc. “While our Smart TV Platforms showed the expected seasonal decline, we are confident that its underlying strength and design wins will drive our revenue growth in fiscal 2017. We also continue to build momentum in IoT Devices with our Z-Wave family, which showed some sequential growth in the fourth quarter.

“We are also pleased with our financial results for all of fiscal 2016. Our revenue grew more than 20% for the year, reaching a total of $227.3 million, with SmartTV and IoT Devices being the largest growth contributors. Supported by a blended non-GAAP gross margin of 51.4% for the year, our non-GAAP net income grew this year, reaching a total of $13.2 million, or 36 cents per diluted share. As we enter fiscal 2017, I am confident that we will see another year of revenue growth and profitability driven by our strong and differentiated products serving both established and new customers.”

Use of Non-GAAP Financial Information

In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, Sigma reports non-GAAP net income (loss), which excludes amortization of acquired intangibles, stock-based compensation, one-time legal fee expenses, settlement expenses, net gain on sale of and impairment of privately-held investments, restructuring charges, 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. Our management does not itself, nor does it suggest that investors should, consider such non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. However, we have presented 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 our core, ongoing business operations.
