Glass Lewis and Clarity AI Merge to Connect Governance and Sustainability Data
Glass Lewis and Clarity AI have completed a strategic merger that brings together two established providers of governance, investment stewardship, and sustainability intelligence tools.
The transaction closed on September 23, 2026, according to the companies, with financial terms remaining undisclosed. Glass Lewis and Clarity AI will initially continue operating under their existing names and brands, while the combined company prepares a new branding strategy expected to be introduced in 2027.
The combination reflects growing demand among institutional investors for investment, sustainability and governance information to be connected across a single workflow rather than handled through separate platforms and datasets.
Glass Lewis specializes in corporate governance research, proxy voting and investment stewardship, while Clarity AI provides technology and sustainability data designed to support areas including portfolio construction, sustainability analysis, risk management and regulatory reporting. Bringing those capabilities together could give investors greater continuity between decisions made before an investment and the stewardship activities that follow.
Connecting Investment Analysis and Stewardship
The companies said the combined platform will cover activities ranging from portfolio construction and monitoring to research, corporate engagement, voting, and reporting.
This is particularly relevant for institutional investors managing large portfolios. Sustainability information, proxy voting recommendations, governance assessments, and portfolio data are frequently sourced from different providers. That can create differences in methodologies, company identifiers, reporting formats, and underlying datasets.
The merger is intended to reduce some of that fragmentation by connecting Clarity AI's sustainability datasets and artificial intelligence capabilities with Glass Lewis' governance research and voting infrastructure.
According to the companies, existing products will continue to be supported while integration takes place gradually. A central objective will be to combine Clarity AI's data capabilities with Glass Lewis' governance expertise while maintaining transparency and auditability in investment analytics.
The companies have also emphasized that Glass Lewis' research and voting services will continue to operate with the governance and controls required for independent proxy advisory activities.
That distinction could be important as investors increasingly integrate environmental and social information into stewardship decisions while still expecting proxy research and voting recommendations to follow established processes.
Complementary Geographic Positions
The deal also combines different geographic strengths.
Glass Lewis has a significant presence in the United States and provides governance and proxy voting services to more than 1,300 investment managers and pension funds globally. Founded in 2003 and headquartered in San Francisco, the company has offices across the United States, Europe, the United Kingdom, Asia and Australia.
Clarity AI, founded in 2017, has built a particularly strong presence in Europe, where sustainability disclosure requirements and responsible investment regulations have driven demand for increasingly detailed environmental, social and governance data.
The combined organization will have more than 900 employees across approximately 20 offices worldwide, according to ESG Dive. It also plans to establish a global center of excellence for sustainability, data and artificial intelligence innovation in Madrid.
Europe is expected to remain an important focus for the business. The companies said the merger should allow them to provide European institutional investors with broader sustainability capabilities, additional local expertise and products designed around changing regulatory and stewardship requirements.
Sustainability Data Becomes part of a Wider Investment Infrastructure
The merger also illustrates a broader change in the sustainability technology market.
Sustainability data was once frequently treated as a separate research category. It is increasingly being incorporated directly into investment analysis, regulatory reporting, risk management and ownership decisions.
Clarity AI, for example, provides data covering public and private companies, investment funds and sovereign entities. Its tools help financial institutions turn environmental and other non-financial information into data they can use for investment and compliance processes.
Glass Lewis operates at a different stage of the investment cycle. Investors primarily use its research and technology when exercising ownership rights, including evaluating corporate governance practices and voting at shareholder meetings.
Connecting the two could allow portfolio-level sustainability assessments to feed more directly into engagement or voting workflows, although the practical impact will depend on how deeply the companies integrate their datasets, platforms and methodologies.
AI Takes a Larger Role in Sustainability Analysis
Artificial intelligence is another significant component of the transaction.
Clarity AI has built its platform around technology that processes large volumes of sustainability and extra-financial information. The company combines automated analysis with research methodologies and specialist oversight, with an emphasis on traceability and transparency in the underlying data.
Under the combined business, AI could increasingly be used to organize corporate disclosures, identify relevant sustainability information and connect investment data with stewardship activities.
For institutional investors, the potential advantage is not simply greater access to data. The more significant issue is whether technology can reduce the work required to reconcile information from different sources while maintaining enough transparency for investors to understand how conclusions were generated.
This becomes particularly important when sustainability information is used for regulated disclosures or influences voting and engagement decisions.
What the Merger Means for Institutional Investors
For asset managers, pension funds and other institutional investors, the transaction points toward further consolidation of sustainability, governance and investment technology.
Rather than maintaining separate systems for ESG analysis, governance research, engagement management, proxy voting and reporting, investors are increasingly being offered platforms intended to connect several of these activities.
A more integrated approach could reduce duplicated data collection and help investment teams maintain consistent information across portfolio management, stewardship and disclosure processes.
However, integration will also place greater importance on issues including methodology transparency, data quality and governance. As platforms cover a wider part of the investment process, users will need to understand where information originates, how AI systems process it and whether analytical and voting functions remain appropriately separated where required.
Glass Lewis and Clarity AI have said their products will be integrated in phases rather than immediately replaced. This means the practical implications for clients are likely to become clearer as the combined company begins introducing shared products and its new brand structure in 2027.
For the sustainability data industry more broadly, the deal highlights how ESG information is becoming increasingly connected with mainstream investment infrastructure rather than operating as a standalone category.
