Impact verdict

Low impact. The only plausible insurance pathway is third-party premises-liability claims against building owners or operators for cooling-tower or water-system maintenance failures β€” a narrow, geographically constrained exposure well below specialty market materiality. There is no evidence of mass casualty, insured property damage, aggregation risk across insured commercial portfolios, or any cyber, political, or terrorism indicator.
