AIG’s turnaround now faces a weather test

01 Running thesis

Turnaround proof, with a caveat

AIG’s latest quarter gave investors a clear sign that the underwriting reset is working. In insurance, underwriting profit means the company collected more in premiums than it paid in claims and related costs. In Q1 2026, General Insurance underwriting income rose to $774 million, and the combined ratio improved by 8.5 points to 87.3%. A combined ratio below 100% means underwriting is profitable.

The bull case is simple. AIG is pricing risk better, cutting weak business, and using its capital base in a more focused way. The company also raised its quarterly dividend by 11% to $0.50 per share and repurchased about 7 million shares for roughly $0.5 billion in Q1 2026. The CEO transition from Peter Zaffino to Eric Andersen is complete, and Andersen has said he will keep the current strategy.

The bear case is also clear. Q1 had a quiet catastrophe backdrop, with catastrophe losses down to $180 million from $525 million a year earlier. That helped the numbers a lot. AIG still has long-tail casualty risk, where claims can show up years after policies are written. The next test is not whether AIG can look good in a calm quarter, but whether it can stay disciplined when loss activity returns to normal.

There are new growth pieces to watch. AIG has invested in Convex and Onex, acquired renewal rights for about $2 billion of Everest retail commercial P&C premiums, and formed partnerships with Blackstone, Amwins, and CVC. These moves could add fee income and better returns, but the company still needs to prove the expected profit and timing.

May 2026Q1 2026 confirmed the underwriting turnaround, with the General Insurance combined ratio improving to 87.3%. The CEO handoff to Eric Andersen is complete, which reduces a key uncertainty.
May 2026The Q1 2026 10-Q showed $774 million of underwriting income, helped by lower catastrophe losses and better prior year reserve development. AIG also repurchased about 7 million shares for roughly $0.5 billion.
Feb 2026The 2025 10-K showed a full-year combined ratio of 90.1% and $2.3 billion of underwriting income. It also added a clear AI risk disclosure.
Feb 2026Q4 2025 results showed a combined ratio of 88.8% and continued capital returns. Management also highlighted Syndicate 2479 with Blackstone and Amwins, plus the CVC partnership.
Nov 2025AIG announced investments in Convex and Onex, plus renewal rights for about $2 billion of Everest commercial P&C premiums. These deals add growth, but also raise execution risk.
Nov 2025The Q3 2025 10-Q supported the capital return case, with $5.3 billion of share repurchases in the first nine months of 2025. Lower catastrophe losses also helped underwriting results.
Aug 2025Management said casualty growth was deliberate and pointed to strong submissions in casualty lines. It also guided toward the high end of the 2025 buyback range.
Aug 2025The Q2 2025 10-Q showed $4.0 billion of share repurchases in the first half of 2025. The accident year combined ratio rose slightly, so underlying margin quality remained a watch item.
02 Business model

Premiums, float, and partner capital

AIG makes money by underwriting insurance risks and investing the premiums it holds before claims are paid. That pool of premiums is called float. If AIG prices policies well, it can earn underwriting profit and investment income at the same time.

The core business is commercial property and casualty insurance. AIG covers risks like property damage, business interruption, liability, cyber, directors and officers claims, aviation, marine, and political risk. These are complex policies, so scale, claims history, and underwriting skill matter.

The model is moving beyond pure organic growth. AIG has a 35% equity stake and a quota share agreement with Convex Group, a 9.9% equity stake in Onex, and renewal rights for about $2 billion of Everest retail commercial P&C gross premiums written. It also has capital-light partnerships, including Syndicate 2479 with Blackstone and Amwins, plus a private equity secondaries platform with CVC.

This can improve returns if AIG picks the right risks and partners. It can also break if acquired renewal rights are underpriced, if partner economics disappoint, or if casualty claims from old policy years develop worse than expected.

03 Product portfolio

What AIG sells

Steady

Property and short-tail insurance

This covers commercial property damage and business interruption. It can be profitable when priced well, but storms and other large events can make results swing.

Growth engine

Casualty insurance

This includes general liability, workers’ compensation, and excess casualty. It is a major growth area, but claims can take years to settle, which raises reserve risk.

Steady

Financial lines

AIG sells D&O, M&A, cyber, and professional liability coverage. These lines depend on careful pricing because legal costs and claim severity can change fast.

Cash cow

Global specialty

This includes marine, aviation, political risk, and trade credit insurance. AIG’s global network helps here because many customers need coverage across borders.

Steady

Global accident and health

This includes group personal accident and business travel insurance. It gives AIG personal insurance exposure without relying only on home and auto.

Option

Personal lines and high-net-worth coverage

AIG offers personal auto, homeowners, and coverage for high-net-worth customers through Private Client Select. This business can be hit hard by catastrophe losses.

Option

Everest renewal rights portfolio

AIG acquired renewal rights for about $2 billion of Everest retail commercial P&C gross premiums written. The portfolio is weighted toward casualty, property, and financial lines.

04 Business segments

Q1 profit mix

North America Commercial42%growing fast
International Commercial36%modest
Global Personal22%growing fast

The segment mix uses Q1 2026 underwriting income from General Insurance: $327 million in North America Commercial, $278 million in International Commercial, and $169 million in Global Personal. This is a profit mix, not a premium mix, so it can move a lot when catastrophe losses change.

05 Risk factors

What could go wrong

Catastrophe losses snap back

High impact · Medium odds

AIG’s Q1 2026 result was helped by a calm catastrophe quarter. Catastrophe losses were $180 million, down from $525 million in Q1 2025. If storms, wildfires, or other large events return to a normal or worse level, the combined ratio could rise fast.

We watchWatch quarterly catastrophe losses and the General Insurance combined ratio.

Long-tail casualty claims worsen

High impact · Medium odds

Casualty policies can produce claims years after the policy is written. If courts, medical costs, or settlement values rise faster than AIG priced for, reserves may need to increase. That would hurt earnings and weaken the turnaround story.

We watchWatch prior year reserve development, especially in casualty lines.

Everest renewal rights underdeliver

Medium impact · Medium odds

AIG acquired renewal rights for about $2 billion of Everest retail commercial P&C gross premiums written. The deal can add scale, but AIG still has to renew, re-underwrite, and price the book well. Poor retention or weak pricing would reduce the expected benefit.

We watchWatch management comments on retention, expected combined ratio, and profitability of the Everest portfolio.

Partner deals miss return targets

Medium impact · Medium odds

AIG is adding growth through Convex, Onex, Syndicate 2479 with Blackstone and Amwins, and the CVC platform. These can be capital-light sources of earnings, but the economics are still not fully visible to outside investors. If fee income or ROE contribution is delayed, the market may view the strategy as less valuable.

We watchWatch for specific fee income, EPS, and ROE targets tied to Convex, Syndicate 2479, and CVC.

New leadership changes execution

Medium impact · Low odds

Eric Andersen has taken over as CEO and has backed the current plan. That lowers transition risk, but execution still matters. A small change in risk appetite, capital return pace, or expense control could change how investors value AIG.

We watchWatch CEO comments on underwriting targets, buybacks, dividends, and strategic investments.

AI tools create operational risk

Medium impact · Low odds

AIG uses AI in parts of underwriting and claims, including AIG Assist. This may improve speed and consistency, but it also adds legal, security, model, and regulatory risks. The company has disclosed that generative AI use may create business and reputation challenges.

We watchWatch disclosures on AI controls, underwriting errors, cybersecurity issues, and regulator feedback.
06 Quick answers

In one breath

What does AIG do?

AIG sells property and casualty insurance around the world. Its main focus is commercial insurance, where it covers risks like property damage, liability, cyber, aviation, marine, and financial claims.

Why did AIG’s Q1 2026 results look strong?

AIG’s General Insurance combined ratio improved to 87.3%, which means underwriting was profitable. A big reason was lower catastrophe losses, which fell to $180 million from $525 million a year earlier.

Is AIG mainly a dividend and buyback story?

Capital returns are a major part of the story. AIG raised its quarterly dividend by 11% to $0.50 per share and repurchased about $0.5 billion of stock in Q1 2026. The story is also shifting toward selected growth deals and partnerships.

What is the biggest risk for AIG investors?

The biggest watch item is whether the underwriting improvement holds when catastrophe activity and casualty claims are less favorable. If the combined ratio rises back toward weaker levels, the turnaround case would be less convincing.
