• Gross margin under U.S. generally accepted accounting principles (GAAP) for the fourth quarter of fiscal 2019 was 60.0%, compared with 64.3% for the same period in fiscal 2018. For the fiscal year ending January 31, 2019, GAAP gross margin was 60.7%, compared with 63.6% for the fiscal year ending January 31, 2018.

• GAAP net loss for the fourth quarter of fiscal 2019 was $4.5 million, or loss per diluted ordinary share of $0.14, compared with GAAP net income of $1.3 million, or earnings per diluted ordinary share of $0.04, for the same period in fiscal 2018. GAAP net loss for the fiscal year ending January 31, 2019 was $30.4 million, or loss per diluted ordinary share of $0.93. This compares with GAAP net income of $18.9 million, or earnings per diluted ordinary share of $0.55, for the fiscal year ending January 31, 2018.

Financial results on anon-GAAP basis for the fourth quarter of fiscal 2019 are as follows:

• Gross margin on anon-GAAP basis for the fourth quarter of fiscal 2019 was 60.6%, compared with 64.7% for the same period in fiscal 2018. For the fiscal year ending January 31, 2019,non-GAAP gross margin was 61.2%, compared with 64.0% for the fiscal year ending January 31, 2018.

• Non-GAAP net income for the fourth quarter of fiscal 2019 was $4.5 million, or earnings per diluted ordinary share of $0.14. This compares with adjustednon-GAAP net income of $16.4 million, or earnings per diluted ordinary share of $0.47, for the same period in fiscal 2018.Non-GAAP net income for the fiscal year ending January 31, 2019 was $24.5 million, or earnings per diluted ordinary share of $0.73. This compares with adjustednon-GAAP net income of $80.3 million, or earnings per diluted ordinary share of $2.32, for the fiscal year ending January 31, 2018.

Based on information available as of today, Ambarella is offering the following guidance for the first quarter of fiscal year 2020, ending April 30, 2019:

• Revenue is expected to be $47.0 million plus or minus 3%

• Gross margin on anon-GAAP basis is expected to be between 59.0% and 60.0%

• Non-GAAP operating expenses are expected to be between $30.5 million and $32.5 million

Ambarella reports gross margin, net income (loss) and earnings (losses) per share in accordance with GAAP and, additionally, on anon-GAAP basis.Non-GAAP financial information excludes the impact of stock-based compensation adjusted for the associated tax impact, which includes the effect of any benefits or shortfalls recognized.Non-GAAP financial information also excludes the impact of the release of a valuation allowance on certain deferred tax assets. Thenon-GAAP net income for fiscal year 2019 includes a change in the allocation of stock-based compensation across the company’s tax jurisdictions to improve alignment of thenon-GAAP tax rate to the GAAP tax rate. Accordingly,non-GAAP net income andnon-GAAP earnings per share for the fourth quarter and fiscal year 2018 ending January 31, 2018 have been adjusted for the change innon-GAAP income tax effect and presented consistent with the fiscal year 2019 presentation. The prior yearnon-GAAP tax rate for the fourth quarter ending January 31, 2018 was reduced from 5.9% to 2.0% resulting innon-GAAP earnings per diluted ordinary share increasing from $0.45 to $0.47. Thenon-GAAP tax rate for the fiscal year ending January 31, 2018 was reduced from 13.5% to 2.8% resulting in thenon-GAAP earnings per diluted ordinary share increasing from $2.06 to $2.32. A reconciliation of the GAAP tonon-GAAP gross margin, net income (loss) and earnings (losses) per share numbers for the periods presented, as well as a description of the items excluded from thenon-GAAP calculations, is included in the financial statements portion of this press release.

Total cash, cash equivalents and marketable securities on hand at the end of the fourth quarter of fiscal 2019 was $358.9 million, compared with $434.6 million at the end of the same quarter a year ago.

“Strategically, fiscal 2019 was one of the most important years in Ambarella’s 15 year history as the company continued to execute on its transformation from a pure video processing company to a computer vision company,” said Fermi Wang, President and CEO. “Wetaped-out and sampled three 10nm computer visionsystem-on-a-chip devices and commenced mass production of one of the devices, all in the fiscal year. Despite the decline in our consumer electronics business, and the geopolitical and macroeconomic headwinds, we have and will continue to focus our investment on computer vision. While it is early in the computer vision adoption cycle, we are excited about expanding our portfolio and having more customers enter mass production.

Non-GAAP Financial Measures

The company has provided in this releasenon-GAAP financial information, includingnon-GAAP gross margin, net income, and earnings per share, as a supplement to the consolidated financial statements, which are prepared in accordance with generally accepted accounting principles (“GAAP”). Management uses thesenon-GAAP financial measures internally in analyzing the company’s financial results to assess operational performance and liquidity. The company believes that both management and investors benefit from referring to thesenon-GAAP financial measures in assessing its performance and when planning, forecasting and analyzing future periods. Further, the company believes thesenon-GAAP financial measures are useful to investors because they allow for greater transparency with respect to key financial metrics that the company uses in making operating decisions and because the company believes that investors and analysts use them to help assess the health of its business and for comparison to other companies.Non-GAAP results are presented for supplemental informational purposes only for understanding the company’s operating results. Thenon-GAAP information should not be considered a substitute for financial information presented in accordance with GAAP, and may be different fromnon-GAAP measures used by other companies.

With respect to its financial results for the fourth quarter of fiscal year 2019, the company has provided below reconciliations of itsnon-GAAP financial measures to its most directly comparable GAAP financial measures. With respect to the company’s expectations for the first quarter of fiscal year 2020, a reconciliation ofnon-GAAP gross margin andnon-GAAP operating expenses guidance to the closest corresponding GAAP measure is not available without unreasonable efforts on a forward-looking basis due to the high variability and low visibility with respect to the charges excluded from thesenon-GAAP measures. We expect the variability of the above charges to have a significant, and potentially unpredictable, impact on our future GAAP financial results.
