AIG’s Q1 2026 results showed strong underwriting momentum, with adjusted EPS up 80% and General Insurance premiums rising 18% in constant dollars. The stock looks fairly valued for now, balancing improving capital returns against property pricing pressure and catastrophe risk.
AIG is a Hold for moderate-risk investors with a medium-term horizon. The investment case rests on stronger underwriting, improving capital returns, and a forward earnings profile that is more attractive than the headline revenue growth rate. In Q1 2026, adjusted after-tax income per diluted share reached $2.11, up 80.0% year over year, while General Insurance net premiums written increased 18.0% on a constant-dollar basis.
The central strength is execution. General Insurance produced an 87.3% calendar-year combined ratio, underwriting income rose to $774M, and core operating ROE reached 12.2%. AIG also returned $760M to shareholders in the quarter and raised its quarterly dividend 11.0% to $0.50. The counterweight is valuation discipline: the shares carry a trailing P/E of 14.0x and a forward P/E of 9.8x, but the company still faces property pricing pressure, catastrophe exposure, and a leadership transition scheduled for June 1, 2026.
American International Group(AIG) is a New York-based global insurance company founded in 1919. It employs approximately 22,100 people and operates in Financial Services through the Insurance sector, with a focus on diversified property and casualty coverage. AIG serves commercial, institutional, and individual customers across more than 200 countries and jurisdictions.
The current AIG is more focused than the conglomerate investors knew before its divestitures. Its operating structure centers on North America Commercial, International Commercial, and Global Personal. The company earns from premiums, underwriting income, investment income, and capital deployment through dividends and share repurchases. The 2025 annual data show $26.8B of revenue, $3.1B of net income, and $3.3B of operating cash flow.
Management is also in the middle of a planned succession. Eric Andersen joined as president and CEO-elect and is scheduled to become CEO on June 1, 2026, while Peter Zaffino is moving into the executive chairman role. Andersen reaffirmed AIG's Investor Day objectives, including operating EPS compound annual growth above 20.0% through 2027 and core operating ROE of 10.0% to 13.0% through 2027.
General Insurance is the economic center of AIG. Q1 2026 net premiums written were $5.6B, up 24.0% on a reported basis and 18.0% in constant dollars. Gross premiums written were $10.0B, up 11.0%, while net premiums earned increased 5.0% to $6.1B. The segment generated $1.6B of adjusted pretax income, up 67.0% year over year.
North America Commercial produced $1.6B of net premiums written, up 37.0% year over year, and $327M of underwriting income. Its 85.5% combined ratio remained excellent, although the adjusted accident-year ratio increased 120 basis points as AIG reduced selected property lines and earned in more casualty business. Retail Excess Casualty pricing increased 14.0%, and Lexington Casualty pricing increased 8.0%, supporting the segment's liability exposure.
International Commercial generated $2.5B of net premiums written, up 21.0% reported and 12.0% in constant dollars. Underwriting income increased 16.0% to $278M, and the combined ratio improved to 87.3%. The segment has delivered 12 consecutive quarters with a combined ratio below 90.0%, a useful marker of consistency in a business where one bad year can erase several good ones.
Global Personal Insurance is the clearest turnaround inside the portfolio. Net premiums written increased 11.0%, its expense ratio declined 410 basis points, and its adjusted accident-year combined ratio improved 570 basis points to 89.9%. The calendar-year combined ratio was 89.4%, compared with 107.9% in the prior-year quarter. That improvement gives AIG a more profitable platform from which to pursue selective growth.

The closest thing to a flagship AIG product is its global commercial risk platform. It combines property, business interruption, general liability, environmental liability, commercial auto, workers' compensation, excess casualty, professional liability, marine, energy, aviation, political risk, trade credit, and structured programs. That breadth matters most for large corporate and multinational customers that need several policies coordinated across jurisdictions.
Commercial property remains a major product area, but its economics are mixed. AIG's global property portfolio carries approximately $6.5B of gross premiums written, with International Property representing about 40.0%. International Property posted calendar-year combined ratios in the low 70s across 2024 and 2025, while North American Retail Property also produced combined ratios in the 70s during those years.
The pressure point is U.S. large-account property. North America Property pricing decreased 11.0% in Q1 2026, and new business in Lexington's large-account shared and layered portfolio declined 19.0% year over year. AIG is responding by reducing capacity in accounts that no longer meet its risk-adjusted return requirements. That is a better product strategy than defending volume for its own sake.
AIG's competitive advantage is built on global scale, underwriting expertise, distribution, claims capabilities, and financial capacity. The company is adding technology to that foundation rather than treating artificial intelligence as a replacement for underwriting judgment. In 2025, AIG launched Underwriting by AIG Assist and expanded the program across eight lines of business.
The reported results give the AI strategy more substance than a slide full of fashionable nouns. AIG is working with Palantir and Anthropic on multi-agent underwriting systems built on Palantir's Foundry platform. The planned agents are designed to handle submission ingestion, data extraction, risk evaluation, pricing benchmarks, and collaboration while keeping human oversight in the workflow.
The advantage will be economic only if better data and faster decisions improve underwriting results or reduce expenses. Q1 2026 provides an early operating signal: the overall General Insurance expense ratio improved 120 basis points to 29.3%, and the adjusted accident-year combined ratio improved to 86.6%. The company has not attributed that entire improvement to AI, but the technology is being deployed in the exact workflows where efficiency and risk selection matter.
AIG's operating chain runs from clients and brokers through underwriting, reinsurance, claims, and investment management. Broker relationships are a critical distribution asset: Global Commercial retention was 88.0% in Q1 2026, with North America Commercial retention at 88.0% and International Commercial retention at 89.0%. Global Commercial new business totaled $1.6B, including Everest renewals, up 42.0% year over year.
Reinsurance is a central operating lever. AIG reported favorable terms and pricing during the January 1 renewal cycle, including the Everest portfolio. Management also emphasized maintaining a consistently low net retention for natural catastrophes, which reduces volatility and allows AIG to redeploy capital toward lines with better risk-adjusted returns.
Claims and reserves also supported the quarter. Catastrophe losses were approximately $180M, down from $525M in the prior-year quarter, and prior-year development was $132M favorable. The favorable reserve development was driven primarily by U.S. Property and Financial Lines. These items helped underwriting income more than triple year over year, although catastrophe results naturally fluctuate from quarter to quarter.
AIG operates inside a large and expanding property and casualty market. The global P&C market is estimated at $3.0T in 2026 and $4.1T by 2031, representing a 6.8% compound annual growth rate. The commercial insurance market is estimated at $1.6T in 2026 and $2.1T by 2031, representing a 5.9% compound annual growth rate.
The most attractive pockets are often more specialized than basic property coverage. Cyber, marine, inland, and surety lines are projected to grow at a 5.5% compound annual rate through 2031. AIG's exposure to marine, energy, political risk, trade credit, aviation, and complex liability gives it a route into those markets, while its global footprint supports multinational programs.
Technology is becoming a second market layered on top of insurance. Global insurance IT spending is forecast at $256B for 2025, while the insurance platform market is projected to reach $207.5B by 2030. AIG's AIG Assist rollout connects directly to that trend, but the investment case still depends on measurable underwriting and expense gains rather than technology adoption alone.

AIG serves three broad customer groups: commercial enterprises, institutional organizations, and individuals. Its commercial customers include large corporations, multinational businesses, middle-market companies, and specialized industries that require coverage for property, liability, employees, trade, energy, marine, and political risks. Its personal products include auto, homeowners, supplemental health, travel, device protection, and high-net-worth coverage.
Large enterprises held 67.1% of commercial insurance premiums in 2025, reflecting the value of tailored, multi-line programs. AIG's 88.0% Global Commercial retention rate indicates that customers and brokers continued to renew despite competitive pricing conditions. The $1.6B of new business also shows that the platform is gaining accounts rather than relying only on renewals.
Customer economics vary by line. Retail Excess Casualty pricing increased 14.0%, while North America Property pricing declined 11.0%. This spread shows why AIG's broad portfolio matters: it can emphasize liability and specialty opportunities while reducing exposure to property layers that no longer offer adequate returns.
AIG competes with Chubb(CB), Travelers(TRV), Zurich, AXA XL, Allianz, CNA, Liberty Mutual, QBE, Tokio Marine, and Berkshire Hathaway(BRK.B) in overlapping commercial and specialty lines. The competitive contest centers on pricing, financial strength, claims performance, broker relationships, capacity, and the ability to underwrite complex risks.
AIG's operating metrics show meaningful progress relative to its own recent history. In 2025, the company reported $2.3B of underwriting income and a 90.1% calendar-year combined ratio. In Q1 2026, underwriting income increased to $774M and the combined ratio improved to 87.3%. Those figures move AIG closer to the performance profile expected from a scaled commercial carrier.
The remaining distinction is consistency. Chubb and Zurich are widely used benchmarks for commercial P&C execution, while AIG is still demonstrating that its transformation can persist through softer pricing and catastrophe volatility. AIG's 12 consecutive quarters below a 90.0% International Commercial combined ratio and its improved Global Personal results provide evidence in favor of the transition.
The Middle East conflict and shifting trade policies are affecting the risk environment AIG underwrites. Management reported increased demand for property and energy, trade credit, and political risk insurance as customers navigate greater uncertainty. AIG said the direct impact on its business was not material based on Q1 observations, while its teams monitored accumulation risk, adjusted underwriting guidelines, and stress-tested the investment portfolio.
Natural catastrophe exposure remains a structural earnings risk. Q1 2026 included $180M of catastrophe losses, led by winter storms, even as the overall combined ratio improved sharply. The 2025 annual report also identifies climate-related disaster frequency and severity, inflation, reserve adequacy, regulatory change, and investment portfolio volatility as important risk factors.
Casualty inflation is another pressure point. Industry data identifies large verdicts, defense costs, and litigation severity as drivers of social inflation, while AIG's own Q1 pricing data show a favorable 14.0% increase in retail Excess Casualty pricing. That pricing support is valuable, but it must continue to exceed claims-cost inflation to protect margins.
AIG returned $760M to shareholders in Q1 2026 while lifting its quarterly dividend 11.0% to $0.50, signaling solid capital flexibility alongside ongoing underwriting discipline.

Get Full Access →AIG has moved from restructuring toward operating execution. Q1 2026 delivered $2.11 of adjusted EPS, $774M of underwriting income, an 87.3% combined ratio, 12.2% core operating ROE, and $760M of shareholder returns. Those are concrete improvements, not merely a better corporate narrative.
The medium-term opportunity is clear: analysts estimate EPS of $7.99 in 2026 and $8.86 in 2027, while management targets more than 20.0% operating EPS compound annual growth through 2027. The risk is equally clear: property pricing is softening, catastrophe losses can reverse quarterly gains, and AIG must prove that its leadership transition and AI investments improve results over multiple periods.
For a moderate-risk portfolio, AIG belongs in the Hold category at the $88.55 fair value estimate. The company has earned the benefit of the doubt through better underwriting and disciplined capital management, but the next leg of appreciation requires those gains to become a durable operating pattern.
