Nasdaq OMX, the second-largest equity market operator in the United States, is combining two technology units that provide advisory services to exchanges and research on company shareholders.
The company said it would merge its market technology and corporate solutions divisions.
Anna Ewing, the executive vice-president of global technology solutions, will lead the new business.
The company named Bradley Peterson global chief information officer. He will assume his position on February 6.
Peterson, who held the position at Charles Schwab, will report to Ewing, who previously held the title.
Nasdaq, trying to expand its business beyond securities transactions, said the reorganisation would help integrate units it was buying from Thomson Reuters that provide investor and public relations products.
