August 29, 2019 — Santa Clara, Calif. — Ambarella, Inc. (NASDAQ: AMBA), a leading developer of low-power and high-resolution human and computer vision solutions, today announced financial results for its second quarter of fiscal year 2020 ended July 31, 2019.

Financial results on a non-GAAP basis for the second quarter of fiscal 2020 are as follows:

Based on information available as of today, Ambarella is offering the following guidance for the third quarter of fiscal year 2020, ending October 31, 2019:

Ambarella reports gross margin, net income (loss) and earnings (losses) per share in accordance with GAAP and, additionally, on a non-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. A reconciliation of the GAAP to non-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 the non-GAAP calculations, is included in the financial statements portion of this press release.

Total cash, cash equivalents and marketable debt securities on hand at the end of the second fiscal quarter of 2020 was $375.8 million, compared with $366.2 million in the prior quarter and $376.0 million at the end of the same quarter a year ago.

“Our confidence in our fiscal year 2020 outlook has increased, despite the geopolitical uncertainty,” said Fermi Wang, President and CEO. “Most importantly, we continue to demonstrate strong progress on our strategy to transform from a pure video processing company to an artificial intelligence (“AI”) video company. During the second quarter, we commenced mass production CV system-on-a-chip (“SoC”) shipments into the automotive market and CV25 became our second CV SoC to generate mass production revenue. We continue to have strong confidence in the three waves of CV revenue we have previously described.”

Stock Repurchase

In the second quarter of fiscal year 2020, the company did not repurchase shares under a $50.0 million repurchase program through June 30, 2020.

Non-GAAP Financial Measures

The company has provided in this release non-GAAP financial information including non-GAAP gross margin, net income, and earnings per share, as a supplement to the condensed consolidated financial statements, which are prepared in accordance with generally accepted accounting principles (“GAAP”). Management uses these non-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 these non-GAAP financial measures in assessing its performance and when planning, forecasting and analyzing future periods. Further, the company believes these non-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. The non-GAAP information should not be considered a substitute for financial information presented in accordance with GAAP, and may be different from non-GAAP measures used by other companies.

With respect to its financial results for the second quarter of fiscal year 2020, the company has provided below reconciliations of its non-GAAP financial measures to its most directly comparable GAAP financial measures. With respect to the company’s expectations for the third quarter of fiscal year 2020, a reconciliation of non-GAAP gross margin and non-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 these non-GAAP measures. We expect the variability of the above charges to have a significant, and potentially unpredictable, impact on our future GAAP financial results.
