Chubb Limited

CB

FAVORABLE

May 22, 2026

Research Conclusion

BUY at ~$285. Chubb is the world's largest publicly traded P&C insurer by NPW ($54.8B FY2025), with combined ratio of 85-87% (vs. industry 95%) demonstrating underwriting discipline under CEO Evan Greenberg. Berkshire owns ~6% (~$7.4B position). At 10.4x FY2026E core EPS, the market gives an orphan multiple despite premier franchise economics. The $169B investment portfolio is repricing from 2.5-3% legacy yields to 5-6% current reinvestment — a structural earnings step-up. PWFV ~$385-398 (+35-40%). Bear case (-2%) is essentially flat — exceptional asymmetry.

Company Overview & Moat Assessment

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%
Primary Debate on Wall Street

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.

  • P&C cycle softens (LOW-MEDIUM probability, MEDIUM-HIGH impact): combined ratio drift
  • Investment yields decline (LOW probability, MEDIUM impact): repricing thesis weakens
