Management Comment

“We had a solid first quarter with revenue increasing for the fourth straight quarter. In addition, we increased our non-GAAP profitability for the third quarter in a row,” said Thinh Tran, president and CEO of Sigma Designs, Inc. “Our higher revenue resulted primarily from a combination of increased customer volumes for both our Smart TV chipsets and IoT Devices. We are committed to sustaining this positive momentum.”

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, facility exit legal 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 and the reversal of previously accrued rebates. 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. 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.

The material limitation associated with the use of the non-GAAP financial measures is that the non-GAAP measures may not reflect the full economic impact of Sigma’s activities. Sigma’s non-GAAP net income (loss) is not prepared in accordance with GAAP, is not an alternative to GAAP financial information, and may be calculated differently than non-GAAP financial information disclosed by other companies. Accordingly, investors are cautioned not to place undue reliance on non-GAAP information.
