By Elena Vasquez, Senior Financial Editor at NorthStar Market Insights: American International Group stands as a cornerstone in global insurance, navigating complex risks with disciplined underwriting and strategic capital allocation.

Core Business Model and 2025 Performance Highlights

AIG operates as a leading global insurance organization, providing property casualty insurance, life and retirement services, and other financial products across more than 80 countries. Its business model emphasizes diversified revenue streams, with a core focus on commercial, specialty, and personal insurance lines, supported by robust reinsurance strategies.

In 2025, underwriting income rose 22% year-over-year to $2.3 billion, reflecting improved pricing discipline and favorable market conditions. The full-year combined ratio stood at 90.1%, with an accident year combined ratio of 88.3%, indicating strong loss control and profitability.

Net premiums written reached $23.7 billion, up 2% on a comparable basis, while net income totaled $3.1 billion or $5.43 per diluted share, reversing a prior-year loss of $2.17 per share. Adjusted after-tax income per diluted share hit $7.09, a 43% increase, placing AIG in the 98th percentile for operating EPS compound annual growth rate among S&P 500 companies over five years.

These results stem from the successful execution of the AIG Next initiative, which delivered over $500 million in run-rate savings through modernization and expense discipline. Core operating return on equity reached 11.1%, surpassing the company's 10%+ target for the first time in over a decade.

Capital Management and Shareholder Returns

AIG's capital allocation strategy remains a key strength, with $6.8 billion returned to shareholders in 2025 through $5.8 billion in share repurchases and $1.0 billion in dividends. This included a 12.5% increase in quarterly dividends starting in Q2 2025, signaling confidence in ongoing cash generation.

Since November 2021, the company has realized nearly $20 billion from its Corebridge Financial holdings via share sales, dividends, and fees, reducing ownership to 10.1% by year-end 2025. This divestiture program has bolstered parent liquidity to $9.3 billion and supported a low 18% debt-to-capital ratio, providing ample flexibility.

Shareholders' equity stood at approximately $41 billion as of December 31, 2025, underpinned by prudent risk management and consistent returns. AIG's global workforce of more than 22,000 colleagues supports these efforts across diverse markets.

In February 2026, AIG acquired a 35% equity stake in Convex, a specialty insurer, and a 9.9% ownership in its majority owner, enhancing its specialty insurance capabilities without straining the balance sheet.

Leadership Transition and Governance Framework

The 2026 proxy statement outlines a planned CEO transition from Peter Zaffino to Eric Andersen on or after June 1, 2026, with Zaffino assuming the role of Executive Chair. This orderly succession follows years of turnaround efforts and aims to ensure continuity.

AIG's board features extensive refreshment, with an average nominee tenure of four years and a framework emphasizing independence, including a strong Lead Independent Director, proxy access, majority voting, and limits on outside board service. The board oversees critical areas like AI, cybersecurity, risk, and human capital.

Shareholder engagement has reached holders representing about three-quarters of shares, fostering transparency. The proxy seeks approval for ten directors, advisory say-on-pay, and ratification of PricewaterhouseCoopers as auditor for 2026, with the annual meeting set virtually for May 13, 2026.

This governance structure positions AIG to address emerging challenges, such as technological disruptions and regulatory shifts, while maintaining accountability to investors.

Competitive Position in the Insurance Sector

AIG holds a prominent position in the global insurance market, particularly in commercial and specialty lines where scale and expertise provide differentiation. Its diversified portfolio mitigates exposure to any single risk class, from multinational corporations to high-net-worth individuals.

Sector drivers include rising demand for cyber insurance, climate-related coverage, and parametric products amid increasing natural catastrophes and digital risks. AIG's combined ratio performance outperforms many peers, reflecting superior underwriting discipline.

Modernization under AIG Next has streamlined operations, reducing the expense ratio and enabling competitive pricing. The Convex investment bolsters specialty offerings, targeting high-margin opportunities in a fragmented market.

Compared to rivals, AIG's capital returns and low leverage stand out, appealing to income-focused investors seeking stability in a cyclical industry.

Relevance for North American Investors

For North American investors, AIG offers exposure to a blue-chip insurer with significant U.S. operations, including personal lines growth and commercial expertise. Its NYSE listing and USD trading provide straightforward access, with dividends appealing to yield seekers.

The 11.1% core ROE and consistent capital returns align with preferences for reliable performers amid economic uncertainty. Institutional interest persists, as seen in ETF holdings increases.

AIG's focus on North America, combined with global diversification, hedges against regional downturns. Investors benefit from its scale in reinsurance and specialty markets, critical for U.S. businesses facing evolving risks.

What matters now is the post-2025 momentum, with leadership continuity ensuring execution on growth initiatives. This setup supports long-term compounding for patient holders.

Risks and Key Factors to Watch

Insurance stocks like AIG face cyclical risks from catastrophe losses, interest rate fluctuations, and investment portfolio volatility. While 2025 ratios were strong, adverse weather or claims inflation could pressure margins.

Regulatory scrutiny in the U.S. and abroad, particularly on solvency and climate disclosures, remains a watchpoint. The CEO transition, though planned, carries execution risks during market stress.

Competition from insurtechs and peers intensifies, requiring ongoing innovation. Investors should monitor catastrophe losses, combined ratio trends, and capital return pace post-Corebridge divestitures.

North American investors should watch Q1 2026 earnings for Convex integration updates, dividend sustainability, and AI oversight progress. Broader sector dynamics, like rate cycles and economic growth, will influence near-term performance.
