Financial Highlights for the Three Months Ended September 30, 2026

•Net income attributable to Chubb was $2.84 billion compared with $2.80 billion in the prior year period, reflecting higher net investment income and higher mark-to-market gains on private equity investments included in other income, partially offset by a decline in P&C underwriting income driven by higher catastrophe losses.

•Total pre-tax catastrophe losses were $705 million, compared with $285 million in the prior year.

•Consolidated net premiums written were $15.1 billion, up 1.9 percent.

•P&C net premiums written increased 1.9 percent, with consumer insurance up 6.2 percent and commercial insurance up 0.4 percent. Consumer insurance growth reflects strong new business and retention, including positive rate and exposure increases. Commercial lines net growth was unfavorably impacted from North America large account property including E&S and financial lines underwriting related exposure changes including additional reinsurance.

•Life Insurance segment net premiums written increased 1.4 percent, as growth in international life from both traditional regular premium products and savings-oriented single premium business was offset by the impact of a one-time large transaction in New Zealand for $126 million in the third quarter of 2025. International life insurance deposits collected increased $341 million, up 68.7 percent. Additionally, net premiums written in our Chubb Benefits business increased $37 million, up 11.7 percent, primarily driven by worksite business.

•Pre-tax net investment income was $1.8 billion, compared with $1.6 billion in the prior year period, primarily due to higher average invested assets and higher interest rates.

•Operating cash flow was $6.1 billion.
