Chubb Limited
CB
May 22, 2026
Chubb Limited is the world's largest publicly traded P&C insurer by net premiums written ($54.8B FY2025), formed from ACE Limited's $28.3B acquisition of original Chubb Corporation in 2016. Domiciled in Zurich, Switzerland. CEO Evan Greenberg (since 2016 merger; age 67). Combined ratio sustained at 85-88% — best-in-class for global P&C. $169B investment portfolio generating $5.5B FY2025 investment income; growing to $8-10B over 3-5 years as bonds reprice. Three earnings streams: underwriting profit (~$6-7B pre-tax), investment income (growing), and modest fee revenue. Berkshire holds ~6% stake.
▲ Bull Case
- ◆Investment income reaches $9B+ by FY2028: $169B portfolio repricing from 2.5-3% to 5-6% yields; full cycle effect adds $3B+ pre-tax annually; structural EPS step-up of $6-11/share over 3-5 years
- ◆Multiple re-rates from 10.4x to 14x as premier franchise recognition: Premium underwriter + Berkshire endorsement + investment income tailwind drives re-rating; bull case 14x FY2028E = $504 (+77%)
- ◆Berkshire eventually acquires Chubb (low probability, embedded optionality): 3-7 year horizon; would deliver 20-25% premium
▼ Bear Case
- ◆Major CAT event (>$5B Chubb loss): Combined ratio temporarily >95%; EPS hit $10-15/share; sentiment compression
- ◆Greenberg retirement announcement triggers multi-year discount: Successor 'prove-it' period; multiple compresses from 1.3x P/BV to 1.0-1.2x
- ◆P&C cycle softens; combined ratio drifts to 90-92%: Underwriting profit compresses; ROE drops to 12-13%
“Whether Chubb's premier underwriter status deserves a premium multiple (bull) or whether the cycle and succession risk justify current 10.4x (bear). Investment income repricing is widely acknowledged but its magnitude is underestimated.”
- ◆Q2 2026 earnings (Jul 2026): Investment income run-rate; combined ratio
- ◆Hurricane season (Jun-Nov 2026): Cat exposure realization
- ◆Investment yield disclosure (Quarterly): Portfolio repricing pace
- ◆Greenberg succession news (Ongoing): Any retirement signal
- ◆Berkshire 13F (Quarterly): Stake position changes
- ◆Major CAT event (MEDIUM probability, HIGH impact): bear materializes
- ◆Greenberg retirement (LOW-MEDIUM probability, HIGH impact): multiple compresses
- ◆P&C cycle softens (LOW-MEDIUM probability, MEDIUM-HIGH impact): combined ratio drift
- ◆Investment yields decline (LOW probability, MEDIUM impact): repricing thesis weakens
- ◆Berkshire sells (LOW probability, LOW-MEDIUM impact): sentiment
