MSCI Acquires First Street to Expand Physical Climate Risk Analytics

MSCI has announced the acquisition of First Street, a leading provider of physics-based climate risk data and analytics covering every property in the world, for a cash payment of $120 million at closing with the potential for additional payments if revenue thresholds are achieved in the first two years following closing. The acquisition integrates First Street's multi-hazard models and property-level climate risk data into MSCI's existing climate and geospatial solutions, enabling quantified assessments of financially relevant physical climate risk at any geographic coordinate and across more than two billion structures worldwide. First Street's own research shows that companies have become more than 6.5 times as likely to issue profit warnings following extreme weather events over the past two decades, providing a direct commercial rationale for embedding physical climate risk analytics into investment and risk management workflows.

 

First Street's Technology and the Climate Risk Financial Modelling Category

 

First Street provides multi-hazard models that incorporate climate signals and are validated against observed events to assess current and future physical risk exposure, asset damage and business interruption, with proprietary data on building characteristics, infrastructure dependencies and site-level adaptation translating physical hazards into measurable financial impact estimates. Matthew Eby, Founder and Chief Executive Officer of First Street, said the company was built on the conviction that every financial decision should account for a changing climate and that First Street built the Climate Risk Financial Modelling category to turn that conviction into reality, describing the MSCI acquisition as putting property-level science in front of the world's leading investors, lenders and insurers. The interactive platform delivers insights through visualisations and on-demand customisable analytics for individual properties, companies and portfolios within a unified AI-enabled workflow, providing the operational interface needed for daily integration into investment and risk management processes rather than periodic reporting exercises.

Richard Mattison, Head of Sustainability and Climate at MSCI, said the financial consequences of where assets are located have come into sharp focus due to geopolitical turmoil, supply chain disruption and the growing impact of climate hazards, and that investors, lenders and insurers are increasingly looking for more in-depth and actionable analysis of physical risk held in the footprint of company operations and investments. He said the integration of First Street data into MSCI's geospatial capabilities will enable clients to better understand their changing risk exposures and translate that directly into financial decision-making, framing the acquisition as a direct response to client demand for physically grounded, location-based climate risk intelligence embedded in investment workflows. The transaction is expected to close in the third quarter of 2026 subject to regulatory approvals, with First Street's financial results to be reported within MSCI's Sustainability and Climate segment following completion.

Regulatory Demand and Institutional Client Requirements

 

The acquisition directly addresses growing regulatory requirements for physical climate risk assessment across the financial sector, with European central banks already using MSCI data to identify climate risks across loan books and the EBA's newly finalised Pillar 3 ESG disclosure framework requiring banks to disclose exposures subject to physical risk by geographic location and hazard type. The TNFD framework's nature and climate-related financial disclosures guidance and TCFD-aligned regulatory requirements across major jurisdictions are progressively mandating that banks, insurers and asset managers demonstrate they have assessed and managed the physical climate risks embedded in their portfolios, creating structural institutional demand for the kind of property-level, financially quantified risk data that First Street provides. Asset location is becoming a critical factor in evaluating investment risk and opportunity as extreme weather events increase in frequency and severity, making the ability to analyse location-based risks a key competitive differentiator for financial institutions managing large and geographically diverse asset portfolios.

The integration of First Street's physics-based climate models with MSCI's existing climate scenario analysis, transition finance and ESG data capabilities creates a more complete physical and transition risk platform than either company offers independently, enabling clients to assess both the transition risk of high-carbon assets and the physical risk of climate-exposed assets within a single analytical framework. For banks and insurers conducting regulatory stress tests under frameworks like the EBA's new 2027 climate stress test module, which requires assessment of both transition and physical risk scenarios, a unified platform with credible models for both risk categories provides significant operational efficiency advantages over maintaining separate systems for each risk dimension.

 

Competitive Positioning in Climate Risk Analytics

 

The First Street acquisition extends MSCI's leadership in climate investment tools and research, building on decades of expertise in geospatial intelligence, climate scenario analysis and transition finance to add property-level physical risk quantification that has previously been a gap relative to specialist physical climate risk data providers. The two billion structure global coverage of First Street's database provides an unprecedented geographic scope for property-level physical climate risk assessment, enabling MSCI clients to assess physical risk exposure across global real estate portfolios, infrastructure assets and corporate operating locations with consistent methodology and data quality. This global coverage is commercially important for institutional investors and multinational companies that need to assess physical climate risk across geographically diverse portfolios spanning multiple climate zones, hazard types and national regulatory contexts.

The acquisition positions MSCI to compete more directly with specialist physical climate risk providers including Jupiter Intelligence, Moody's Analytics and Swiss Re in a market where demand for financially quantified, property-level climate risk data is growing rapidly as regulatory requirements and investor sophistication advance simultaneously. The combination of MSCI's existing institutional client relationships, index and portfolio analytics infrastructure and ESG data capabilities with First Street's physics-based modelling and property-level database creates a competitive offering that is difficult for either standalone ESG data providers or specialist physical risk firms to match without their own comparable combination of capabilities.

Outlook for Physical Climate Risk in Financial Decision-Making

 

The MSCI and First Street combination reflects the accelerating mainstreaming of physical climate risk analytics from a specialist sustainability function into a core component of investment analysis, credit risk assessment and insurance underwriting, driven by the increasing financial materiality of climate hazard events and the expanding regulatory requirements for climate risk disclosure and stress testing. Whether MSCI can successfully integrate First Street's models and data into its existing platform infrastructure and client workflows while maintaining the scientific credibility and model validation standards that institutional clients require will determine how quickly the acquisition delivers commercial value and competitive differentiation. The transaction's revenue threshold structure, providing additional payments if certain targets are achieved in the first two years, aligns incentives toward rapid client adoption and revenue generation rather than extended integration timelines.

Sustained growth in institutional demand for property-level physical climate risk analytics, driven by regulatory requirements, extreme weather event frequency increases and growing fiduciary recognition of climate risk as a material investment consideration, creates structurally favourable conditions for the combined MSCI and First Street platform to capture significant market share in a category that is transitioning from early adoption to mainstream institutional practice.
