The acquisition aims to bolster MSCI's physical climate risk data capabilities, which are critical for financial institutions and investors seeking to mitigate risks associated with natural disasters exacerbated by climate change.

MSCI has been expanding its offerings in environmental, social and governance (ESG) metrics and sustainability reporting. The integration of First Street’s advanced analytics will enhance MSCI's existing ESG solutions, providing clients with more comprehensive data to inform investment decisions.

First Street’s technology platform evaluates physical climate risks such as flooding, heatwaves, hurricanes, droughts, wildfires, extreme cold, sea-level rise and storm surge. These factors are increasingly relevant for financial institutions assessing the resilience of their portfolios against environmental threats.

The deal includes earnouts contingent upon performance milestones to ensure alignment between First Street’s goals and MSCI's long-term strategy.
