American Corporates Tout Adaptation Playbooks in Q3

In the US, extreme weather shocks often peak between July and end-September. This is hurricane season — but it’s also when other dangerous convective storms strike, unleashing torrential rains and howling winds across large parts of North America.

In some ways, Q3 2025 lived up to this reputation. The country watched aghast as deadly floods, charged by relentless rains, swept through Texas in July. Later on, Hurricane Erin — though it never made landfall — brought violent waves and flooding to the Eastern Seaboard. And has become all too routine, the season birthed myriad dangerous wildfires, scorching vast tracts of land in California, Arizona, and other parts of the American West.

However, for America’s largest corporations the impacts of these extreme weather events were muted, according to earnings call transcripts of S&P 500 companies. This may come as little surprise to sharp-eyed corporate analysts. After all, as terrifying as the recent calamities were, they merely brushed against the fabric of corporate America — rather than tearing through it. 

The US experience aligns with worldwide trends. Recent data from Gallagher Re suggests that Q3 2025 saw the lowest climate- and weather-related catastrophe losses this century. While this makes for a welcome respite from the travails of earlier this year, corporate executives did not let up on pushing forward adaptation plans and sounding off on the dangers of extreme weather to their operations.
