Financial Highlights for the Three Months Ended June 30, 2026

•Net income attributable to Chubb was $2.9 billion compared with $3.0 billion in the prior year period, reflecting growth in both P&C underwriting income and Life segment income, and higher net investment income, offset by lower mark-to-market gains on private equity investments.

•Consolidated net premiums written were $14.71 billion, up 3.6 percent.

•P&C net premiums written increased 3.0 percent, with consumer insurance up 8.7 percent and commercial insurance up 0.8 percent. Consumer insurance growth reflects strong new business and retention, including positive rate and exposure increases. Commercial lines growth was unfavorably impacted by underwriting actions in large account and E&S property, which reduced growth by 4.5 percentage points.

•Life Insurance segment net premiums written increased 7.5 percent, due to growth in international life of 6.2 percent reflecting growth in traditional regular premium products of 12.4 percent, offset by lower savings-oriented single premium business. International life insurance deposits collected increased $197 million, up 38.3 percent.

Additionally, our Chubb Benefits business grew 14.0 percent, primarily driven by worksite business.

•Pre-tax net investment income was $1.76 billion, compared with $1.6 billion in the prior year period, primarily due to higher average invested assets.
