Overview

Nomura Securities Co., Ltd. is the principal securities operating company of Nomura Group and a wholly owned subsidiary of Nomura Holdings, Inc. Its activities span Japanese retail investing, institutional securities, global markets, investment banking, merchant banking and asset management. The company is headquartered in Tokyo and operates internationally through the Nomura brand and regionally incorporated affiliates, including Nomura Securities International in the United States and Nomura International in Europe, the Middle East and Africa. The business traces its origins to the financial activities of Tokushichi Nomura and to the securities department of Osaka Nomura Bank. Nomura Securities was formally established in Osaka on December 25, 1925. It initially concentrated on bonds and related securities activities, but expanded as Japan's capital markets developed. A research capability and financial publishing operation helped the firm distribute market information and build a nationwide securities franchise. The company received authorization to trade equities in 1938 and became publicly listed in 1961, before later becoming part of a holding-company structure. Nomura developed an international presence well before the modern globalization of Japanese finance. It opened a New York office in 1927, joined the New York Stock Exchange in 1981 and became a member of the London Stock Exchange in 1986. These steps supported its growth in international brokerage, underwriting and capital-markets services. In 2001, Nomura Holdings adopted a holding-company structure. The existing group was reorganized around Nomura Holdings, while a newly established wholly owned subsidiary retained the Nomura Securities name and took over the securities and financing operations. The firm accelerated its international expansion in the 2000s. It acquired Instinet in 2007, adding brokerage and trading-technology capabilities. During the 2008 financial crisis, Nomura acquired significant parts of Lehman Brothers' operations in Asia-Pacific and its investment-banking and equities businesses in Europe and the Middle East. The transactions gave Nomura additional client relationships, personnel and infrastructure outside Japan, although integrating and making those operations profitable remained a long-term management challenge. Nomura also acquired Tricorn Partners in 2009 to strengthen investment banking and was designated a primary dealer by the Federal Reserve Bank of New York that year. Nomura's Japanese retail business remains an important part of its identity, providing brokerage, investment products, advisory services and financial planning to individual clients. Its institutional and wholesale businesses provide equity and fixed-income trading, research, underwriting, private placements, corporate finance, leveraged finance and other capital-markets services. The firm's global network has included major regional centers in Tokyo, Hong Kong, London and New York, with additional offices across Asia-Pacific, the Americas and EMEA. Nomura Securities is distinct from Nomura Holdings, the listed parent company. Nomura Holdings coordinates the broader group and reports consolidated financial results, while Nomura Securities operates the group's core securities business. Because the subject is a corporate operating subsidiary rather than a separately listed public company, it has no standalone stock ticker. Public information about current executives, detailed financial results and operating structure is generally reported through Nomura Holdings and official regional entities.

History

Nomura Securities traces its origin to the securities business founded by Tokushichi Nomura II in Osaka in 1925. The company emerged from the Nomura group's financial activities and developed as Japan's securities markets expanded. Its early business centered on brokerage and securities distribution, but over time it broadened into underwriting, research, institutional services, and investment banking. During the postwar development of Japan's economy, Nomura became one of the country's largest securities firms. Its domestic network connected individual investors and Japanese companies with the capital markets, while its research and institutional businesses supported professional investors. The firm also developed international offices to serve Japanese clients overseas and to participate in global markets. A significant corporate reorganization occurred in 2001, when Nomura adopted a holding-company structure. Nomura Securities became the principal operating securities company within the reorganized Nomura Group, while Nomura Holdings became the listed parent. This separation allowed the group to manage securities, asset-management, and related businesses within a broader financial-services framework. The 2008 global financial crisis produced the most consequential international expansion in the firm's modern history. Following Lehman Brothers' bankruptcy, Nomura acquired selected Lehman operations in Asia-Pacific, Europe, and the Middle East. These transactions gave Nomura additional employees, clients, research coverage, trading capabilities, and investment-banking infrastructure outside Japan. They also exposed the group to the challenges of integrating businesses acquired across different jurisdictions and managing a larger global cost base. In subsequent years, Nomura continued to operate through domestic retail and wealth-management activities, Japanese and international wholesale businesses, and group capabilities in asset management and related financial services. The firm has periodically adjusted its international strategy, expenses, business mix, and risk controls in response to market conditions. Its Japanese securities franchise remains the foundation of the brand, while its international operations provide cross-border research, advisory, underwriting, sales, trading, and institutional coverage. Nomura Securities is not itself the listed parent. Its corporate position is that of a core subsidiary within Nomura Holdings, Inc., whose group structure provides the governance and capital framework for Nomura's global financial businesses. The brand continues to operate as an active full-service securities firm serving retail, corporate, institutional, and public-sector clients.
