Emerging players

• Manifest: Independent proxy voting and governance advisory firm serving institutional investors as a third-party alternative. Competes in the same proxy advisory category with a focus on customizable voting policies, similar to Glass Lewis's Client Custom Policies offering.
• EOS at Federated Hermes: In-house stewardship and engagement service within Federated Hermes that engages portfolio companies on ESG and governance issues. Represents the buy-side build option that institutional clients could pursue instead of outsourcing to Glass Lewis, particularly relevant given JPMorgan's Proxy IQ precedent.

Broad incumbents

• MSCI ESG Research: Large incumbent ESG ratings and research provider serving institutional investors with sustainability data and analytics. Comparable to Glass Lewis's ESG Profile Data and Climate Intelligence offerings at the investment-research layer, though MSCI operates at much greater scale across a broader product portfolio.
• LSEG (Refinitiv) ESG: London Stock Exchange Group's data and analytics arm (incorporating Refinitiv) offers extensive ESG and governance datasets for institutional investors. Competes with Glass Lewis in the governance data layer and increasingly in climate transition analytics.
• S&P Global Sustainable1: S&P Global's sustainability data and analytics arm offering ESG scores, climate analytics, and governance datasets to institutional investors. Adjacent to Glass Lewis's Climate Intelligence and corporate governance data products, competing for similar institutional ESG research budgets.
• Sustainalytics: Major ESG and corporate governance research provider owned by Morningstar. Direct overlap with Glass Lewis's ESG Profile Data and governance research products for institutional investors, particularly on sustainability ratings and risk analytics.
• Broadridge Financial Solutions: Large incumbent provider of investor communications, proxy processing, and shareholder meeting infrastructure. Competes with Glass Lewis in the broader proxy value chain — particularly around vote processing, N-PX reporting, and share recall — though Broadridge's focus is infrastructure rather than advisory recommendations.

Direct peers

• Georgeson: Proxy solicitation and investor communications firm that overlaps with Glass Lewis's shareholder communications and contested situations business. Comparable B2B client base of corporate issuers and institutional investors, with adjacent service offerings in proxy contests and M&A situations.
• Egan-Jones Proxy Services: Independent proxy advisor offering voting recommendations and governance research to institutional investors. Direct competitor in proxy advice, often positioned as a third alternative to the ISS/Glass Lewis duopoly with overlapping client base.
• Institutional Shareholder Services (ISS): ISS is the other half of the U.S. proxy advisory duopoly, providing the same core service of governance research and proxy voting recommendations to institutional investors. Together the two firms control an estimated 90–97% of the U.S. proxy advisory market, making them direct one-for-one competitors on every major institutional account.
