Forward-Looking Statements

This presentation contains forward-looking statements that are subject to many risks and uncertainties. All statements made in this presentation other than statements of historical facts are forward-looking statements, including, without limitation, statements regarding Ambarella's strategy, future operations, financial targets, future revenues, projected costs, prospects, plans and objectives for future operations, future product introductions, future rate of our revenue growth, the size of markets addressed by the company's solutions and the growth rate of those markets, technology trends, our ability to address market and customer demands and to timely develop new or enhanced solutions to meet those demands, our ability to achieve design wins, and our ability to retain and expand our customer and partner relationships.

In some cases, you can identify forward-looking statements by terms such as "may," "will," "should," "could," "would," "expects," "plans," "anticipates," "believes," "estimates," "projects," "predicts," "potential," or the negative of those terms, and similar expressions and comparable terminology intended to identify forward-looking statements. We have based forward-looking statements largely on our estimates of our financial results and our current expectations and projections about future events, markets and financial trends that we believe may affect our financial condition, results of operations, business strategy, short term and long-term business operations and objectives, and financial needs as of the date of this presentation. Although these forward-looking statements are based upon information available at the time the statements are made and reflect management's good faith beliefs, forward-looking statements inherently involve known and unknown risks, uncertainties and other factors that may cause actual results, performance or achievements to differ materially from anticipated future results. Important factors that could cause actual results to differ materially from expectations are disclosed in Ambarella's annual reports on Form 10-K and quarterly reports and Form 10-Q filed with the Securities and Exchange Commission (the "SEC"), particularly in the sections titled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations." You should not place undue reliance on forward-looking statements, which speak only as of the date on which they are made. We do not undertake to update or revise any forward-looking statements after they are made, whether as a result of new information, future events, or otherwise, except as required by applicable law. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this presentation may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward- looking statements.

Before you invest, you should read the annual and quarterly reports and other documents Ambarella has filed with the SEC for more complete information about the company and its ordinary shares. Additional information will also be set forth in Ambarella's future quarterly and annual reports and other filings made with the SEC from time to time. You may access these documents for free by visiting EDGAR on the SEC web site at www.sec.gov.

Ambarella Overview

Ambarella is an artificial intelligence ("AI") vision silicon company

• Ambarella developed over a 4 year period an AI processor architecture specifically optimized for video edge-endpoint applications. The integration of this deep neural network AI processor with the company's state-of-the-art video processor yields a highly optimized computer vision ("CV") system-on-a-chip ("SoC").
• Cumulative investment into CV technology ~$480 million targeting automotive, security camera and other robotic applications.
• CV revenue 10%+ of FY2021 revenue and estimated to be at least 25% of FY2022 revenue. Three "waves" of CV revenue anticipated; professional security cameras (CY2020), smart home security cameras (CY2021) and automotive camera systems (CY2022-23).

Founded 2004, IPO (NASDAQ: AMBA) 2012

• Focused on video applications, always with the premise that video is a special type of data requiring an optimized chip architecture.
• Initially targeted human viewing applications with low-power and high-resolution SoCs for the consumer and security camera markets.
• New CV SoCs enable machines to visually perceive and make decisions, enabling higher levels of automation in multiple industries.

Strong and liquid balance sheet

• $441 million cash and marketable securities and no debt exiting Q4 FY2021 (January 31, 2021).
• Returned $176 million to shareholders via stock repurchases in the last 4 years.

Ambarella Addresses the Edge Endpoints of the IoT Market

• The IoT endpoint market, the foundation of the pyramid, requires a fundamentally different SoC architecture versus the server- based network edge and datacenter layers

• Ambarella is focused on IoT endpoints where low power, highly efficient processing, low latency and improved privacy and security are critical

• IoT endpoint market is a high volume and diverse market
