Global proxy advisory firm Glass Lewis is set to overhaul the way it delivers shareholder voting research and recommendations, moving away from a single standardized model toward a more customized, investor-driven approach. The decision reflects deepening divisions among investors across regions particularly between the U.S. and Europe on issues such as ESG, diversity, and corporate accountability.

A Shift from Uniformity to Personalization

For decades, proxy advisors like Glass Lewis and ISS have shaped how institutional investors vote on key corporate issues, offering uniform recommendations based on internal “house” policies. But as investor values and regional regulations diverge, that model is becoming obsolete. Glass Lewis announced that it will no longer provide singular proxy voting advice. Instead, beginning in 2027, clients will be able to access multiple perspectives that reflect distinct investment philosophies and stewardship priorities ranging from management-aligned viewpoints to governance-focused or sustainability-oriented frameworks.

“As institutional investors take increasingly different approaches to voting preferences, the traditional one-size-fits-all model of proxy advice no longer meets the needs of a diverse client base,” said Bob Mann, CEO of Glass Lewis. “Investors want guidance that mirrors their own strategies, values, and stewardship goals.”

Political Pressure and Global Polarization

The company’s move also comes amid mounting political scrutiny in the U.S., where several Republican-led states have accused proxy advisors of promoting ESG agendas that allegedly conflict with fiduciary duties. In recent weeks, Texas Attorney General Ken Paxton launched an investigation into both Glass Lewis and its competitor Institutional Shareholder Services (ISS), claiming that their ESG-related recommendations may have “misled investors.” Glass Lewis cited these “diverging investor priorities” as a key reason for its overhaul, noting that approaches to corporate governance, climate risk, and diversity have begun to split sharply between American and European investors. The company said that while many European institutions continue to prioritize ESG integration and climate accountability, a growing segment of U.S. asset managers are retreating from sustainability-linked engagement amid political backlash and legal risks.

Technology Enables Tailored Voting Strategies

Glass Lewis’ shift also leverages new AI and data-driven technologies that make it possible to personalize proxy research at scale. Instead of relying on a universal recommendation, investors will be able to design their own voting frameworks, using the firm’s technology to reflect specific fiduciary mandates, portfolio goals, or stakeholder expectations. The advisory firm said it will help clients “move beyond standard policies” and guide them in developing bespoke stewardship models that mirror their unique investment outlooks. This evolution marks one of the most significant structural changes in the proxy advisory industry since its inception potentially redefining how institutional stewardship operates in a fragmented global landscape.

Implications for the Proxy Voting Industry

The proxy voting ecosystem, long dominated by a handful of advisory firms, has faced growing criticism from both regulators and corporations. In the U.S., regulators and conservative lawmakers have accused firms like Glass Lewis and ISS of holding outsized influence on shareholder decisions, particularly around climate and social resolutions. In Europe, however, investors and regulators have pushed for greater integration of sustainability metrics into voting decisions. The EU’s Sustainable Finance Disclosure Regulation (SFDR) and corporate sustainability reporting frameworks have reinforced expectations that institutional investors align votes with long-term ESG commitments. By moving to a multi-perspective model, Glass Lewis may be attempting to bridge these contrasting regional demands offering flexibility to U.S. investors while maintaining credibility with ESG-aligned European clients.

A Redefinition of Fiduciary Duty

At the heart of this transformation lies a broader question: what does fiduciary duty mean in a world where environmental and social factors are politically contested? Glass Lewis’ new framework signals that the answer may now depend on where investors operate and what their stakeholders expect. As Mann emphasized, the future of proxy advice will be pluralistic, not prescriptive.

“Investors no longer want a universal viewpoint, they want frameworks that reflect their own stewardship priorities,” Mann said.

With implementation planned over the next two years, Glass Lewis’ model may set a new industry precedent, reshaping how the world’s largest investors navigate the widening fault line between ESG advocacy and fiduciary conservatism.
