Institutional Shareholder Services

ISS STOXX, the combined entity formed from Institutional Shareholder Services and Deutsche Börse's index business, spans proxy voting, sustainability data, indices, and corporate advisory. Its client base includes the world's leading institutional investors and corporate issuers. The firm operates out of headquarters in Rockville, Maryland, with over 30 offices worldwide. Its stewardship arm, ISS STOXX Governance, produces roughly 45,000 proxy analyses annually and supports 480 custom voting policies (all metrics as of December 31, 2025). The sustainability unit feeds research into 2.8 million data points. ISS STOXX Indices includes the STOXX and DAX families, which are used by ETF issuers, derivatives providers, and structured-product markets. ISS-Corporate advises companies on governance, compensation, and sustainability reporting. ISS Market Intelligence provides data and analytics to financial services firms. Geographic coverage spans the Americas, Europe, and Asia-Pacific. The firm employs 790 research professionals globally and reports 99.5% index data accuracy within STOXX and DAX. In April 2026, ISS STOXX announced planned AI-enabled solutions aimed at enhancing its analytics and voting recommendations (per the firm, April 2026). The organization is part of Deutsche Börse Group, which provides public ownership and regulatory infrastructure. ISS STOXX integrates an index business and a governance-advisory platform under one roof, which is unusual among proxy-advisory firms. This vertical structure allows it to supply both the benchmarks and the stewardship tools that institutional investors rely on — making the firm a dual-sided participant in capital markets infrastructure rather than a pure research provider.
