Described by his peers as a “talented and proven leader,” Kwaku Ntoso is a highly respected, seasoned professional with over 15 years of experience in the financial services industry. As an executive director at Mizuho Securities in New York, Kwaku’s current focus and expertise is in the power and utilities space. He also has experience covering other industries including energy, healthcare, international trade, and municipal finance. His vast array of specialties includes managing client relationships, originating deals, executing transactions, leading diverse teams, and providing companies with strategic solutions.

Kwaku’s primary client responsibilities include advising power and utilities companies on business strategy, financing plans, raising capital, and acquisition finance. There are a variety of sub-sectors that make up the power and utilities space, including regulated utilities, diversified utilities, renewable solar and wind companies, and generation-only independent power producers.


As part of his work within the power and utilities industry, Kwaku has helped companies finance over $3 billion in solar and wind projects both domestically and internationally. His efforts have helped decrease the carbon footprint in the United States, Canada, and Japan, in addition to achieving financial gains for both the companies and banks involved in the business deals.

Supported by a global platform, team members work to customize solutions to meet the diverse needs of clients. Bank services include corporate and investment banking, capital markets, and project finance, among others.  


In 2015, Mizuho acquired the ~$36.5 billion Royal Bank of Scotland (RBS) North American loan portfolio. The acquisition further accelerated the growth strategy Mizuho has pursued post-financial crisis and the expansion into different product areas. As a large global bank, Mizuho currently holds over $2 trillion in assets.


Prior to joining Mizuho in 2011, Kwaku was an associate in the power and utilities group at UBS Investment Bank from 2008 – 2011.

Kwaku has always enjoyed assisting others throughout his career and is specifically keen on recruiting more talent into the financial services and power and utilities industries. Kwaku explains, “I have always loved helping people. The financial services industry is one of the most powerful and dynamic spaces to influence change through capital allocation. Furthermore, the stability and necessity of the power and utilities industry as well as the advancement of renewable technology and the impact it has on the environment is why I enjoy working in this field. I look forward to continuing my career in this space for years to come.”


Outside of his career, Kwaku enjoys investing, mentoring, volunteering, travel, fitness, and reading. Most of all, he enjoys spending time with his 5 year old daughter, Belle-Janvier.
