Message Introduction Clients Our People Society Message from the Group CEO Working with pride and integrity Kentaro Okuda President and Group CEO Nomura’s management vision is to achieve sustainable growth by helping resolve social issues. We believe that the sustainable development of society as a whole will help enhance our corporate value. Our business is built on the trust of our clients and all stakeholders. The trust our clients place in each employee represents trust placed in the overall group. Therefore, if one person does something that undermines the trust of our clients, the entire group loses trust. The Code of Conduct serves as our guide for ethical decision-making and proper conduct as we work to build trust. If you are ever unsure of what to do, always consider whether your decision or action is something you could proudly share with your family and close friends. It is important that we think about how we can contribute to the organization and the people in our team, and be proactive. A critical part of this is speaking up when something is not right, and creating an environment that supports people who speak up. I believe that a diverse organization is crucial to such an environment. As a member of Nomura Group, we have a responsibility to do more than just comply with rules and regulations. Let us all work together to build a firm where our people conduct themselves with integrity at all times and take pride in everything they do. 03 CODE of CONDUCT 2022 04 NOMURA

CONDUCT for CLIENTS 15 CODE of CONDUCT 2022 Message Introduction Clients Our people Society We always place our clients at the heart of everything we do. To continue to be the most trusted partner for our clients, we collaborate with our team members and provide high quality service. CONDUCT for CLIENTS 01 Pursue the best interests of our clients 17 02 Continually enhance our expertise and capabilities 19 03 Leverage our collective strength 21 04 Be the most trusted partner for our clients 23 05 uphold the highest standards of compliance 25 06 Handle information properly 27 16 NOMURA

CONDUCT for CLIENTS Pursue the best interests of our clients We serve clients with respect, and understand their needs and interests We provide thorough explanation considering the client’s understanding and experience We strive to provide proposals that exceed client expectations Whether or not you have opportunities to directly serve our clients, always keep in mind how our businesses can affect them Acting in the best interests of our clients means providing the optimal financial solution to meet our clients’ needs while also observing the Code of Conduct. Best interests does not necessarily mean maximizing economic interests, but rather developing and providing products and services from the client’s perspective. Furthermore, pursuing the best interests of the client also means to advise when you think something they asked you is not in their best interests. 01 To pursue the best interests of our clients: What does the best interests of our clients actually mean? We strive to meet our clients’ expectations by understanding their needs and proposing suitable products and services. CODE of CONDUCT 2022 17 18 Message Introduction Clients Our People Society

CONDUCT for CLIENTS Continually enhance our expertise and 02 capabilities We stay on top of the latest trends in financial and capital markets around the world We enhance our ability to identify risks our clients are exposed to We build our knowledge of both financial and other fields There have been many cases where unexpected events have resulted in severe losses. These include events that you thought would never occur because they hadn’t occurred in the past, or those that very rarely occur. It is important to recognize that some risks can be easily identified, while others are rare but can cause significant loss once they become apparent. To serve our clients with expertise: “Unknown” risk We enhance our expertise and capabilities to put forward the best proposals to our clients. We properly assess the risks our clients are exposed to and take appropriate actions in a timely manner. CODE of CONDUCT 2022 19 20 Message Introduction Clients Our People Society

CONDUCT for CLIENTS Leverage 03 our collective strength We understand the functions and roles of each division and department We stay up to date on the wide range of businesses and services we offer We proactively collaborate across various functions To leverage our collective strength: We provide optimal solutions to our clients by making full use of our collective strength. We work together across countries and regions to deliver our competitive edge. Nomura Group has various functions. If you face client needs which you haven’t faced before, you should make full use of our diverse resources, such as consulting with your colleagues, your manager or contact relevant departments in the firm to meet their needs. You should also try to take an interest in the activities of other departments and develop internal networks. Leverage our collective strength CODE of CONDUCT 2022 21 22 Message Introduction Clients Our People Society

CONDUCT for CLIENTS Be the most trusted 04 partner for our clients We will propose products and services appropriate for each client We will provide information in accordance with the client’s investment experience We will improve the quality of our operations and avoid causing inconvenience to our clients due to errors in administrative procedures We will keep our clients informed and remain direct and prompt even in difficult communications We will let clients know our concerns if something they propose will not be beneficial for them Just because it is not against the law does not mean we can do anything that our clients request. Activities that undermine market integrity, and behavior that deviates from social norms are ultimately not beneficial for our clients. You should not be driven by immediate profits and should ask yourself if your actions will help build long-term relationships of trust with clients. Then, you should go back to “Nomura Five YES” and check if what you are about to do is appropriate. To continue to be the most trusted partner for our clients: What does “for the client” mean? We will always place our clients at the heart of everything we do, deal with them with integrity, and build long-term relationships of trust. CODE of CONDUCT 2022 23 24 Message Introduction Clients Our People Society

CONDUCT for CLIENTS Uphold the highest 05 standards of compliance The following are examples of acts that are strictly prohibited Clients may make wrong investment decisions if we fail to properly explain the nature and risks of financial products and services. Violation of the Duty of Explanation As a global investment bank, we act as an intermediary between the markets and our clients. We manage potential conflicts of interest appropriately to ensure our clients’ interests are not adversely affected. Conflict of Interest We work to protect our clients’ interests at all times. We act with integrity towards all our clients. If proper client verification is not carried out prior to a transaction and fraudulent activities occur, we will be unable to prevent proceeds of financial crime from entering into capital markets and terrorism funding. Money Laundering If we fail to prevent transactions with criminal organizations or their members, this can result in financing their illegal activities. Organized Crime Such conduct undermines the development of a sound economy. This will enable organized crime and allow terrorists to expand their sources of funding. We must maintain robust controls to prevent these activities. If someone enters into a transaction using material non-public information (“MNPI”) not known to others, that person will have an unfair advantage over other investors. We are committed to protecting market integrity. The use of MNPI for the benefit of a specific investor is unfair. Insider Trading If transactions intended to artificially change or peg prices are executed, investor decisions will be adversely affected and this will impede the fair operation of the markets. Market Manipulation Such conduct undermines market integrity and will lead to a loss of investor trust in the market. Given our role as a gatekeeper for capital markets, we do not tolerate such activities and work to prevent them. We must also act in accordance with principles of fair dealing and good faith. We strictly comply with applicable laws and regulations. In addition, we work with the highest level of compliance awareness to protect our clients and ensure market integrity. CODE of CONDUCT 2022 25 26 Message Introduction Clients Our People Society

CONDUCT for CLIENTS Handle information properly We strictly manage entrusted client information and only use it in accordance with our client’s understanding.

We properly manage internal information to protect the credibility of Nomura Group. 06 Details regarding Nomura’s business operations and other company information must not be shared with outside parties, including former employees. If you receive requests for client information from outside parties, promptly report to your manager. If you are contacted by the media, do not respond based on your own judgment. Promptly contact your regional Corporate Communications Department and follow their instructions. Handling of Nomura Group information I believe it will benefit our clients if we promptly communicate information that is to their advantage. If it’s not prohibited by law such as insider information, there’s no issue, right? Q We must always consider market integrity and fairness.

CONDUCT for OUR PEOPLE What kind of risks are there and what actions are required? These are the major risks that require action. Managing risks inherent to our business Appropriate management is required on risks such as “market risk” which is the possibility of incurring losses from market volatility affecting interest rates, currency rates and stock, and “credit risk”, which is the possibility of the firm incurring default losses due to failure of a counterparty (borrower) to honor its contractual obligations, such as derivative investment and financing transactions. Unavoidable risks Among “operational risks”, risks that cannot be completely prevented in business operations, such as human error, and risks caused by external factors, such as natural disasters and third party failures, are included. Efforts to minimize these risks is crucial. Prohibited risks Among operational risks, risks that violate laws and regulations, and adversely affect market fairness, soundness and client protection are included. Efforts are required to eliminate these risks. Q A We understand we are accountable, have ownership in risk management and will be proactive in mind and action without leaving things to others In order to maintain trust from all of our stakeholders, we will not only comply with the rules and regulations concerning risk management but also take appropriate actions with integrity, based on understandings of the purpose and background of the rules, and with the highest expertise and ethical standards required of financial institutions We acknowledge we may underestimate risks or take wrong actions.
