Chubb Limited (CB) 2025 Earnings Quality Report

Grade: A — Strong Financial Health

Framework: Insurance-specific analysis (combined ratio, loss ratio, underwriting income, reserve adequacy, investment income) + Schilit principles

Data: SEC EDGAR 10-K (Filed 2026-02-27, FY ended December 31, 2025) + Yahoo Finance

Auditor: PricewaterhouseCoopers LLP — Unqualified opinion (1 Critical Audit Matter)

One-line verdict: Chubb is the world's largest publicly traded P&C insurance company — $54.8B in net premiums written, $10.3B in net income, and a P&C combined ratio of 85.7% that improved for the third consecutive year. The screening engine assigns Grade A with zero fails, one watch item (goodwill at 40% of equity), and seven N/A checks. Cash flow quality is excellent (CFFO/NI = 1.24). Total assets of $272B and shareholders' equity of $74B provide a fortress balance sheet for an insurer. The Beneish M-Score and Altman Z-Score are not applicable to insurance companies. This is one of the cleanest financial statements in the insurance sector.

The World's Largest P&C Insurer

Per the 10-K:

Net income grew 11.2% to $10.3B on revenue growth of 6.5%. Net premiums written grew 6.6% (7.0% on a constant-dollar basis). Net investment income surged 9% to $6.5B, driven by higher reinvestment yields — the filing shows a yield on average invested assets of 4.5% with a market yield on fixed maturities of 5.0%.

The filing states: "Chubb was incorporated in 1985" and "we had total assets of $272 billion and total shareholders' equity of $74 billion (excluding noncontrolling interests)."

Underwriting Performance: Best-in-Class

Per the filing:

A P&C combined ratio of 85.7% means Chubb earns 14.3 cents of underwriting profit on every dollar of premium — before investment income. The current accident year combined ratio excluding catastrophe losses improved to 81.9%, the best in the three-year period shown.

Per the filing: "The P&C combined ratio and the P&C CAY combined ratio excluding catastrophe losses decreased in 2025, reflecting lower losses, partially offset by an increase in the policy acquisition cost ratio."

Prior period development was 2.5% favorable — meaning reserves established in prior years proved more than adequate, releasing into current-year earnings. This is a sign of conservative reserving.

Investment Portfolio

Per the filing:

Invested assets grew to $144B, generating $6.5B in investment income. The market yield on fixed maturities (5.0%) exceeds the portfolio yield (4.5%), meaning as older, lower-yielding bonds mature and are reinvested, investment income will continue to rise. This "embedded yield improvement" is a multi-year tailwind.

Segments

Chubb operates through five segments:

Per the filing, "In 2025, consolidated net premiums earned (NPE) was $53.0 billion."

The 18-Point Screening

Revenue Quality

All revenue quality checks pass. AR growing slower than revenue is a healthy signal.

Expense Quality

Cash Flow Quality

Cash flow quality is excellent. CFFO exceeds net income by 24%, and the accruals ratio is negative — meaning cash generation exceeds reported earnings. Cash covers debt 2.5x.

Balance Sheet

D1 — Goodwill at 40% of equity reflects past acquisitions, most notably the 2016 Chubb/ACE merger. At 40%, this is below the 50% fail threshold but warrants monitoring. Goodwill is stable (+1% YoY), suggesting no new acquisition-driven risk.

Acquisition Risk & Manipulation

Key Risks from the 10-K

1. Catastrophe Losses

Catastrophe losses consumed 6.3% of the combined ratio in 2025, up from 5.5% in 2024 and 4.5% in 2023. The filing warns about "losses arising out of natural or man-made catastrophes." Climate change is increasing the frequency and severity of insured events, putting upward pressure on loss ratios over time.

2. Loss Reserve Uncertainty

The filing's critical audit matter focuses on loss reserves. Per the filing: the company must assess "the potential losses associated with the risks that we insure and reinsure" and "establish reserves for unpaid losses and loss expenses, which are estimates of future payments of reported and unreported claims." If actual claims exceed reserves, financial results would be adversely affected. The 2.5% favorable prior period development provides a current-year cushion, but reserves are inherently uncertain, especially for long-tail casualty lines.

3. Huatai Group (China)

Chubb has a significant investment in Huatai Group, a Chinese insurance and financial services conglomerate. Geopolitical tensions between the U.S. and China create regulatory and political risk for this investment. The filing discloses Huatai Group's asset management activities, including competition for AUM in China.

4. Regulatory and Legal Risk

As a global insurer operating in numerous jurisdictions, Chubb faces complex regulatory requirements. The filing warns about "asbestos-related latent injuries" and other long-tail liabilities.

Summary

Grade: A. Strong financial health. The world's largest P&C insurer with an improving combined ratio, excellent cash flow quality, and a fortress balance sheet.

Chubb's FY2025 is textbook insurance quality: P&C combined ratio of 85.7% (improving), net income of $10.3B (+11%), CFFO/NI of 1.24, cash covering debt 2.5x, and stable goodwill at 40% of equity. PricewaterhouseCoopers issued an unqualified opinion.

Zero red flags. One watch item (goodwill). The CAY combined ratio excluding catastrophes of 81.9% is best-in-class underwriting performance.

The risks are embedded in the insurance business model itself: catastrophe exposure, reserve estimation uncertainty, and long-tail liability. These are the inherent risks of being an insurer, not signs of financial manipulation or weakness.
