EXHIBIT A (Requirements for trading plans)

INTRODUCTION

Ambarella, Inc. (together with any subsidiaries, collectively the “Company”) has adopted this Insider Trading Policy (the “Policy”) to help you comply with the federal and state securities laws and regulations that govern trading in securities and to help the Company minimize its own legal and reputational risk.

It is your responsibility to understand and follow this Policy. Insider trading is illegal and a violation of this Policy. In addition to your own liability for insider trading, the Company, as well as individual directors, officers and other supervisory personnel, could face liability. Even the appearance of insider trading can lead to government investigations or lawsuits that are time-consuming, expensive and can lead to criminal and civil liability, including damages and fines, imprisonment and bars on serving as an officer or director of a public company, not to mention irreparable damage to both your and the Company’s reputation.

Compliance Officer

Please direct any questions, requests or reports as to any of the matters discussed in this Policy to the Company’s General Counsel (the “Compliance Officer”). The Compliance Officer is generally responsible for the administration of this Policy. The Compliance Officer may select others to assist with the execution of his or her duties.

Reporting violations

It is your responsibility to help enforce this Policy. You should be alert to possible violations and promptly report violations or suspected violations of this Policy to the Compliance Officer, or, if the Compliance Officer is implicated in your report, then you should report it in accordance with the Company’s Whistleblower Policy.

Personal responsibility

The ultimate responsibility for complying with this Policy and applicable laws and regulations rests with you. You should use your best judgment at all times and consult with your legal and financial advisors, as needed. We advise you to seek assistance if you have any questions at all. The rules relating to insider trading can be complex, and a violation of insider trading laws can carry severe consequences.

Breach and disciplinary effects

The provisions of this Policy are binding on the employees of Ambarella, Inc. and its worldwide subsidiaries and are considered an addition to any applicable disciplinary code.

PERSONS AND TRANSACTIONS COVERED BY THIS POLICY

Persons covered by this Policy

This Policy applies to all directors, officers, employees, consultants, contractors and advisors of the Company. References in this Policy to “you” (as well as general references to directors, officers, employees, consultants, contractors and advisors of the Company) should also be understood to include members of your immediate family, persons with whom you share a household, persons that are your economic dependents and any other individuals or entities whose transactions in securities you influence, direct or control (including, for example, a venture or other investment fund, if you influence, direct or control transactions by the fund). You are responsible for making sure that these other individuals and entities comply with this Policy.

Types of transactions covered by this Policy

Except as discussed in the section entitled “Limited Exceptions”, this Policy applies to all transactions involving the securities of the Company or the securities of other companies as to which you possess material nonpublic information obtained in the course of your service with the Company. This Policy therefore applies to purchases, sales, loans and other transfers of common stock, options, warrants, preferred stock, debt securities (such as debentures, bonds and notes) and other securities, and any offer to engage in the foregoing transactions. This Policy also applies to any arrangements that affect economic exposure to changes in the prices of these securities and any offer to engage in such transactions. These arrangements may include, among other things, transactions in derivative securities (such as exchange‑traded put or call options, swaps, caps and collars), hedging and pledging transactions, short sales and certain decisions with respect to participation in benefit plans. This Policy further applies to any disposition in the form of a gift of any securities of the Company and any distribution to holders of interests in an entity if the entity is subject to this Policy. You should note that there are no exceptions from insider trading laws or this Policy based on the size of the transaction.

Responsibilities regarding the nonpublic information of other companies

Material nonpublic information about another company that you learn through your service with the Company is subject to the same restrictions around disclosure and trading and you cannot use that information to trade securities. Any such action will be deemed a violation of this Policy. .

Applicability of this Policy after your departure

You are expected to comply with this Policy until such time as you are no longer affiliated with the Company and you no longer possess any material nonpublic information subject to this Policy. In addition, if you are subject to a trading blackout under this Policy at the time you cease to be affiliated with the Company, you are expected to abide by the applicable trading restrictions until at least the end of the relevant blackout period.

No exceptions based on personal circumstances

There may be instances where you suffer financial harm or other hardship or are otherwise required to forego a planned transaction because of the restrictions imposed by this Policy. Personal financial emergency or other personal circumstances are not mitigating factors under securities laws and will not excuse a failure to comply with this Policy.

MATERIAL NONPUBLIC INFORMATION

“Material” information

Information should be regarded as material if there is a substantial likelihood that a reasonable investor would consider it important in deciding whether to buy, hold or sell securities or would view the information as significantly altering the total mix of information in the marketplace about the issuer of the security. In general, any information that could reasonably be expected to affect the market price of a security is likely to be material. Either positive or negative information may be material.

It is not possible to define all categories of “material” information. However, some examples of information that would often be regarded as material include, but are not limited to:

If you have any questions as to whether information should be considered “material”, you should consult with the Compliance Officer. In general, it is advisable to resolve any close questions as to the materiality of any information by assuming that the information is material.

“Nonpublic” information

Information is considered nonpublic if the information is not generally known or made available to the public. Even if information is widely known throughout the Company, it may still be nonpublic. As a general rule, information should be considered nonpublic until at least two full trading days have elapsed after the information is broadly distributed to the public in a press release, a public filing with the Securities and Exchange Commission (the “SEC”), a pre-announced public webcast or another broad, non-exclusionary form of public communication. However, depending upon the form of the announcement and the nature of the information, it is possible that information may not be fully absorbed by the marketplace until a later time. Any questions as to whether information is nonpublic should be directed to the Compliance Officer.

The term “trading day” means a day on which national stock exchanges and the National Association of Securities Dealers, Inc. Automated Quotation System are open for trading. A “full” trading day has elapsed when, after the public disclosure, trading in the relevant security has opened and then closed.

POLICIES REGARDING MATERIAL NONPUBLIC INFORMATION

Confidentiality of nonpublic information

The unauthorized use or disclosure of nonpublic information relating to the Company or other companies is prohibited. All nonpublic information you acquire in the course of your service with the Company may only be used for legitimate Company business purposes. In addition, nonpublic information of others should be handled in accordance with the terms of any relevant nondisclosure agreements and other obligations that the Company has with them, and the use of any such nonpublic information should be limited to the purpose for which it was disclosed.

You must use all reasonable efforts to safeguard nonpublic information in the Company’s possession. You may not disclose nonpublic information about the Company or any other company, unless required by law, or unless (i) disclosure is required for legitimate Company business purposes, (ii) you are authorized to disclose the information and (iii) appropriate steps have been taken to prevent misuse of that information (including entering an appropriate nondisclosure agreement that restricts the disclosure and use of the information, if applicable). This restriction also applies to internal communications within the Company and to communications with agents of the Company. In cases where disclosing nonpublic information to third parties is required, you should coordinate with the Legal Department.

No trading on material nonpublic information

Except as discussed in the section entitled “Limited Exceptions”, you may not, directly or indirectly through others, engage, or offer to engage, in any transaction involving the Company’s securities while aware of material nonpublic information relating to the Company. It is not an excuse that you did not “use” the information in your transaction.

Similarly, you may not engage, or offer to engage, in transactions involving the securities of any other company if you are aware of material nonpublic information about that company (except to the extent the transactions are analogous to those presented in the section entitled “Limited Exceptions”). For example, you may be involved in a proposed transaction involving a prospective business relationship or transaction with another company. If information about that transaction constitutes material nonpublic information for that other company, you would be prohibited from engaging in transactions involving the securities of that other company (as well as transactions involving Company securities, if that information is material to the Company). It is important to note that “materiality” is different for different companies. Information that is not material to the Company may be material to another company.

No disclosing material nonpublic information

You may not disclose material nonpublic information concerning the Company or any other company to friends, family members or any other person or entity not authorized to receive such information, except directly to the SEC in compliance with the Company’s Whistleblower Policy. In addition, you may not make recommendations or express opinions on the basis of material nonpublic information as to trading in the securities of companies to which such information relates. In particular, you may not participate, in any manner other than passive observation, in any message board or social media platform messaging relating to the Company’s securities. You are prohibited from engaging in these actions whether or not you derive any profit or personal benefit from doing so.

Obligation to disclose material nonpublic information to the Company

You may not enter into any transaction, including those discussed in the section entitled “Limited Exceptions”, unless you have disclosed any material nonpublic information that you become aware of in the course of your service with the Company, and that senior management is not aware of, to the Compliance Officer. If you are a member of senior management, the information must be disclosed to the Chief Executive Officer, and if you are the Chief Executive Officer or a director, you must disclose the information to the board of directors, before any transaction is permissible.

Responding to outside inquiries for information

In the event you receive an inquiry from someone outside of the Company, such as a stock analyst, for information, you should refer the inquiry to the Chief Financial Officer. The Company is required under Regulation FD (Fair Disclosure) of the U.S. federal securities laws to avoid the selective disclosure of material nonpublic information. In general, the regulation provides that when a public company discloses material nonpublic information, it must provide broad, non-exclusionary access to the information. Violations of this regulation can subject the company to SEC enforcement actions, which may result in injunctions and severe monetary penalties. The Company has established procedures for releasing material information in a manner that is designed to achieve broad public dissemination of the information immediately upon its release in compliance with applicable law. Please consult the Company’s External Communications Policy for more details.

TRADING BLACKOUT PERIODS

To limit the likelihood of trading at times when there is a significant risk of insider trading exposure, the Company has instituted quarterly trading blackout periods and may institute special trading blackout periods from time to time. In addition, to comply with applicable legal requirements, the Company may also institute blackout periods that prevent directors and officers from trading in Company securities at a time when employees are prevented from trading Company securities in the Company’s 401(k) plan.

It is important to note that whether or not you are subject to blackout periods, you remain subject to the prohibitions on trading on the basis of material nonpublic information and any other applicable restrictions in this Policy.

Quarterly blackout periods

Except as discussed in the section entitled “Limited Exceptions”, all directors and executive officers, and those other employees, consultants, contractors and advisors identified by the Company must refrain from conducting transactions involving the Company’s securities during quarterly blackout periods. Even if you are not specifically identified as being subject to quarterly blackout periods, you should exercise caution when engaging in transactions during quarterly blackout periods because of the heightened risk of insider trading exposure.

Quarterly blackout periods begin at the end of the day on the fifteenth day of the third month of each fiscal quarter and end at the start of the third full trading day following the date of public disclosure of the financial results for that fiscal quarter. This period is a particularly sensitive time for transactions involving the Company’s securities from the perspective of compliance with applicable securities laws due to the fact that, during this period, individuals may often possess or have access to material nonpublic information relevant to the expected financial results for the quarter.

Individuals subject to quarterly blackout periods will be informed by the Compliance Officer that they are listed on the covered persons list maintained by the Compliance Officer (the “Covered Persons List”). From time to time, the Company may identify other persons who should be subject to quarterly blackout periods, and the Compliance Officer may update and revise the Covered Persons List as appropriate. To the extent applicable to you, quarterly blackout periods also cover your immediate family members, persons with whom you share a household, persons who are your economic dependents and any entity whose transactions in securities you influence, direct or control.

Special blackout periods

From time to time, the Company may also prohibit directors, officers, employees, consultants, contractors and advisors from engaging in transactions involving the Company’s securities when, in the judgment of the Compliance Officer, a trading blackout is warranted. The Company will generally impose special blackout periods when there are material developments known to the Company that have not yet been disclosed to the public. For example, the Company may impose a special blackout period in anticipation of announcing interim earnings guidance or a significant transaction or business development. However, special blackout periods may be declared for any reason.

The Company will notify in writing or via email those persons subject a special blackout period. Each person who has been so identified and notified by the Company may not engage, or offer

to engage, in any transaction involving the Company’s securities until instructed otherwise by the Compliance Officer, and should not disclose to others the fact of such suspension of trading. To the extent applicable to you, special blackout periods also cover your immediate family members, persons with whom you share a household, persons who are your economic dependents and any entity whose transactions in securities you influence, direct or control.

Regulation BTR blackouts

Directors and executive officers may also be subject to trading blackouts pursuant to Regulation Blackout Trading Restriction, or Regulation BTR, under U.S. federal securities laws. In general, Regulation BTR prohibits any director or executive officer from engaging in certain transactions involving Company securities during periods when 401(k) plan participants are prevented from purchasing, selling or otherwise acquiring or transferring an interest in certain securities held in individual account plans. Any profits realized from a transaction that violates Regulation BTR are recoverable by the Company, regardless of the intentions of the director or officer effecting the transaction. In addition, individuals who engage in such transactions are subject to sanction by the SEC as well as potential criminal liability.

The Company will notify directors and officers if they are subject to a blackout trading restriction under Regulation BTR. Failure to comply with an applicable trading blackout in accordance with Regulation BTR is a violation of law and this Policy.

No “safe harbors”

There are no unconditional “safe harbors” for trades made at particular times, and all persons subject to this Policy should exercise good judgment at all times. Even when a quarterly blackout period is not in effect, you may be prohibited from engaging in transactions involving the Company’s securities because you possess material nonpublic information, are subject to a special blackout period or are otherwise restricted under this Policy.

PRE-CLEARANCE OF TRADES

Except as discussed in the section entitled “Limited Exceptions”, directors and executive officers should refrain from engaging in any transaction involving the Company’s securities without first obtaining pre‑clearance of the transaction from the Compliance Officer. In addition, the Company has determined that certain other employees and agents of the Company that may have regular or special access to material nonpublic information should refrain from engaging in any transaction involving the Company’s securities without first obtaining pre‑clearance of the transaction from the Compliance Officer. Accordingly, the Company’s directors and officers and any other persons identified on the Covered Persons List as being subject to pre-clearance requirements must obtain pre-clearance prior to trading the Company’s securities. The pre-clearance request must be made on the form provided by the Compliance Officer. The Compliance Officer may not engage in a transaction involving the Company’s securities unless the Chief Financial Officer has pre‑cleared the transaction. All trades must be executed within four business days of any pre-clearance. From time to time, the Company may identify other persons who should be subject to the pre‑clearance requirements set forth above, and the Compliance Officer may update and revise the Covered Persons List as appropriate.

These pre-clearance procedures are intended to decrease insider trading risks associated with transactions by individuals with regular or special access to material nonpublic information. In addition, requiring pre‑clearance of transactions by directors and officers facilitates compliance with Rule 144 resale restrictions under the Securities Act, the liability and reporting provisions of Section 16 under the Exchange Act and Regulation BTR. Pre-clearance of a trade, however, is not a defense to a claim of insider trading and does not excuse you from otherwise complying with insider trading laws or this Policy.

Even after pre-clearance, a person may not trade the Company’s securities if they become subject to a blackout period or aware of material nonpublic information prior to the trade being executed.

The Compliance Officer is under no obligation to approve a transaction submitted for pre‑clearance, and may determine not to permit the transaction.

ADDITIONAL RESTRICTIONS AND GUIDANCE

This section addresses certain types of transactions that may expose you and the Company to significant risks. You may not engage in any of the following types of transactions other than as noted below, regardless of whether you have material nonpublic information. You should understand that, even though a transaction may not be expressly prohibited by this section, you are responsible for ensuring that the transaction otherwise complies with other provisions in this Policy that may apply to the transaction, such as the general prohibition against insider trading as well as pre-clearance procedures and blackout periods, to the extent applicable.

Short sales

Short sales (i.e., the sale of a security that must be borrowed to make delivery) and “selling short against the box” (i.e., a sale with a delayed delivery) with respect to Company securities are prohibited under this Policy.

Derivative securities and hedging transactions

If you are required to comply with the blackout periods or pre-clearance requirements under this Policy (i.e., if you are listed on the Covered Persons List), you are prohibited from engaging in transactions in publicly-traded options, such as puts and calls, and other derivative securities with respect to the Company’s securities. Stock options, stock appreciation rights and other securities issued pursuant to Company benefit plans or other compensatory arrangements with the Company are not subject to this prohibition. You are also prohibited from purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds), or otherwise engage in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of Company securities.

Using Company securities as collateral for loans

If you are required to comply with the blackout periods or pre-clearance requirements under this Policy (i.e., if you are listed on the Covered Persons List), you may not pledge Company securities as collateral for loans or as part of any other pledging transaction.

Holding Company securities in margin accounts

If you are required to comply with the blackout periods or pre-clearance requirements under this Policy (i.e., if you are listed on the Covered Persons List), you may not hold Company securities in margin accounts.

Placing open orders with brokers

Except in accordance with an approved trading plan (as discussed below), you should exercise caution when placing open orders, such as limit orders or stop orders, with brokers, particularly where the order is likely to remain outstanding for an extended period of time. Open orders may result in the execution of a trade at a time when you are aware of material nonpublic information or otherwise are not permitted to trade in Company securities, which may result in inadvertent insider trading violations, Section 16 and Reg. BTR violations (for officers and directors), violations of this Policy and unfavorable publicity for you and the Company. If you are subject to blackout periods or pre-clearance requirements, you should so inform any broker with whom you place any open order at the time it is placed.

LIMITED EXCEPTIONS

The following are certain limited exceptions to the quarterly and special blackout period restrictions and pre-clearance requirements imposed by the Company under this Policy. Please be aware that even if a transaction is subject to an exception to this Policy, you will need to separately assess whether the transaction complies with applicable law. For example, even if a transaction is indicated as exempt from this Policy, you may need to comply with the “short-swing” trading restrictions under Section 16 of the Exchange Act, to the extent applicable. You are responsible for complying with applicable law at all times.

Transactions pursuant to a trading plan that complies with SEC rules

The trading restrictions under this policy do not apply to transactions made pursuant to a valid 10b5-1 trading plan approved by the Company. The Company permits its directors, officers and employees to adopt written 10b5-1 trading plans in order to mitigate the risk of trading on material nonpublic information. These plans allow for individuals to enter into a prearranged trading plan as long as the plan is not established or modified during a blackout period or when the individual is otherwise in possession of material nonpublic information. To be approved by the Company and qualify for the exception to this Policy, any 10b5-1 trading plan adopted by a director, officer or employee must be submitted to the Compliance Officer for approval and comply with the requirements set forth in the Requirements for Trading Plans attached as Exhibit A. If the Compliance Officer is the requester, then the Company’s Chief Financial Officer, or their delegate, must approve the written 10b5-1 trading plan.

Receipt and vesting of stock options, restricted stock units, restricted stock and stock appreciation rights

The trading restrictions under this Policy do not apply to the receipt or vesting of stock options, restricted stock units, restricted stock or stock appreciation rights or other equity compensation awards from the Company.

Exercise of stock options for cash

The trading restrictions under this Policy do not apply to the exercise of stock options where the purchase price of such stock options is paid in cash and there is no other associated market activity.

Net share withholding or sell-to-cover transactions

The trading restrictions under this Policy do not apply to net share withholding with respect to equity awards where shares are withheld by the Company in order to satisfy tax withholding requirements, (x) as required by either the Company’s board of directors (or a committee thereof) or the award agreement governing such equity award or (y) as you elect, if permitted by the Company, so long as the election is irrevocable and made in writing at a time when a trading blackout is not in place and you are not in possession of material nonpublic information. Likewise, the trading restriction under this policy do not apply to sell to cover transactions where shares are sold on your behalf upon vesting of equity awards and sold in order to satisfy tax withholding requirements, (x) as required by either the Company’s board of directors (or a committee thereof) or the award agreement governing such equity award or (y) as you elect, if permitted by the Company, so long as the election is irrevocable and made in writing at a time when a trading blackout is not in place and you are not in possession of material nonpublic information; however,

this exception does not apply to any other market sale for the purposes of paying required withholding.

Purchases from the employee stock purchase plan

The trading restrictions in this Policy do not apply to elections with respect to participation in the Company’s employee stock purchase plan or to purchases of securities under the plan. However, the trading restrictions do apply to any subsequent sales of any such securities.

Certain 401(k) plan transactions

The trading restrictions in this Policy do not apply to purchases of Company stock in the 401(k) plan resulting from periodic contributions to the plan based on your payroll contribution election. The trading restrictions do apply, however, to elections you make under the 401(k) plan to (i) increase or decrease the amount of your contributions under the 401(k) plan if such increase or decrease will increase or decrease the amount of your contributions that will be allocated to a Company stock fund, (ii) increase or decrease the percentage of your contributions that will be allocated to a Company stock fund, (iii) move balances into or out of a Company stock fund, (iv) borrow money against your 401(k) plan account if the loan will result in liquidation of some or all of your Company stock fund balance, and (v) pre‑pay a plan loan if the pre‑payment will result in the allocation of loan proceeds to a Company stock fund.

Stock splits, stock dividends and similar transactions

The trading restrictions under this Policy do not apply to a change in the number of securities held as a result of a stock split or stock dividend applying equally to all securities of a class, or similar transactions.

Laws of descent and distribution; changes in form of beneficial interest

The trading restrictions under this Policy do not apply to transfers by will or the laws of descent and distribution and, provided that prior written notice is provided to the Compliance Officer, distributions or transfers (such as certain tax planning or estate planning transfers) that effect only a change in the form of beneficial interest without changing your pecuniary interest in the Company’s securities.

Other exceptions

Any other exception from this Policy must be approved by the Compliance Officer, in consultation with the Board of Directors or an independent committee of the Board of Directors.

COMPLIANCE WITH SECTION 16 OF THE SECURITIES EXCHANGE ACT

All of the Company’s officers and directors and certain other individuals are required to comply with Section 16 of the Securities and Exchange Act of 1934 and related rules and regulations which set forth reporting obligations, limitations on “short swing” transactions, which are certain matching purchases and sales of the Company’s securities within a six-month period, and limitations on short sales.

To ensure transactions subject to Section 16 requirements are reported on time, each person subject to these requirements must provide the Company with detailed information (for example, trade date, number of shares, exact price, etc.) about his or her transactions involving the Company’s securities.

The Company is available to assist in filing Section 16 reports, but the obligation to comply with Section 16 is personal. If you have any questions, you should check with the Compliance Officer.

ADDITIONAL INFORMATION

Protected Activity Not Prohibited

Nothing in this Policy, or any related guidelines or other documents or information provided in connection with this Policy, shall in any way limit or prohibit you from engaging in any of the protected activities set forth in the Company’s Whistleblower Policy, as amended from time to time.

Amendments

We are committed to continuously reviewing and updating our policies and procedures. The Company therefore reserves the right to amend, alter or terminate this Policy at any time and for any reason, subject to applicable law. Unless otherwise permitted by this Policy, any amendments must be approved by the Board of Directors of the Company. A current copy of the Company’s policies regarding insider trading may be obtained by contacting the Compliance Officer.

* * *

Nothing in this Insider Trading Policy creates or implies an employment contract or term of employment. Employment at the Company is employment at-will. Employment at-will may be terminated with or without cause and with or without notice at any time by the employee or the Company. Nothing in this Insider Trading Policy shall limit the right to terminate employment at-will. No employee of the Company has any authority to enter into any agreement for employment for a specified period of time or to make any agreement or representation contrary to the Company’s policy of employment at-will. Only the Chief Executive Officer of the Company has the authority to make any such agreement, which must be in writing.

The policies in this Insider Trading Policy do not constitute a complete list of Company policies or a complete list of the types of conduct that can result in discipline, up to and including discharge.
