The acquisition aims to enhance MSCI’s climate risk assessment tools with property-level analytics for global structures.
MSCI has agreed to acquire First Street, a climate risk data provider, for $120m in cash, with additional payments tied to revenue performance. The upfront sum will be paid at closing, expected in Q3 2026, pending regulatory approval.
First Street’s models offer multi-hazard risk assessments and property-level analytics, validated against real-world climate events. These capabilities will integrate into MSCI’s existing geospatial and climate tools, expanding coverage to over two billion structures worldwide.
The deal consolidates First Street’s financials into MSCI’s Sustainability and Climate segment, aligning with client demand for physical climate risk insights in financial decision-making.
