Summary

American International Group is a top-3 global commercial and specialty insurer undergoing a structural earnings re-rating following the 2022 spin-off of Corebridge Financial, which transformed AIG from a sprawling financial conglomerate into a focused general insurance platform with an $80 billion investment portfolio and 89% North America commercial retention. The key structural insight is that AIG's EPS growth is a compound function of both earnings improvement and aggressive share count reduction — management is committing $3.5–5 billion annually in buybacks against a market cap of roughly $43 billion, implying 8–10% annual share retirement. At current pricing, the market is valuing AIG at approximately 14x trailing earnings while assigning no meaningful premium to a buyback yield that, at $4 billion annually, represents nearly 10% of market cap. This is a capital return story masquerading as a growth story, and the market has not yet priced either leg correctly. Financially, FY2024 was a transition year distorted by $1.4 billion in net losses tied to restructuring charges, deconsolidation impacts, and legacy costs — underlying underwriting quality was improving throughout. FY2025 marked the inflection: revenue of $20.1 billion, net income of $3.1 billion, and EPS of $5.43 on a materially smaller share count. The combined ratio reached 91.3% in general insurance, the expense ratio fell to 31.1% from 32.0% the prior year, and general insurance net premiums written totalled approximately $17.4 billion. Retention rates of 89% in North America commercial and 87% internationally confirm that AIG's portfolio quality improvements have not come at the cost of volume — a critical underwriting discipline test that the company has passed. Applying a 14x P/E multiple — in line with large-cap diversified commercial insurers at steady-state but below the 16–18x commanded by best-in-class peers such as Chubb — to our FY2026 EPS estimate of $9.85 yields a 12-month price target of $138, representing 79% upside from the current $77.02. The 14x multiple is conservative given the buyback-driven EPS acceleration: by FY2029 we forecast EPS of $27.05, implying the stock at current prices trades at under 3x four-year-forward earnings. As expense ratio improvement materialises, Everest portfolio conversion completes, and buybacks compound, we expect the multiple to re-rate toward 14–15x on a sustainably higher earnings base.

Thesis

1. **The Corebridge separation created a cleaner, higher-return insurance business the market has not yet re-rated** AIG's transformation from a sprawling financial conglomerate — with life insurance, retirement, and general insurance all under one roof — into a pure-play commercial and specialty insurer is structurally complete but not yet priced. The Corebridge IPO and subsequent secondary offerings removed a low-return, capital-intensive life and retirement business that chronically suppressed group ROE. What remains is a general insurance franchise with an $80 billion investment portfolio generating substantial net investment income, a global distribution network across 50+ countries, and improving underwriting margins. The strategic clarity post-separation is already translating into operational discipline. Expense ratio improvement from 32.0% in FY2024 to 31.1% in FY2025 is not yet fully reflecting the elimination of parent expense allocations from Corebridge that will cease entirely in the 2026 run-rate. Management has guided to below 30% expense ratio by 2027, and our forecasts project 28.5% in FY2026 and sub-28% by FY2027 — a 300+ basis point structural improvement from the pre-separation baseline. For context, each 100 basis points of expense ratio improvement on $17+ billion of net premiums written is worth approximately $170 million of pre-tax underwriting income annually. The full improvement arc represents nearly $700 million of incremental annual earnings power, none of which is in the current share price. 2. **Everest portfolio conversion is a near-term, high-visibility premium growth catalyst** AIG's acquisition of renewal rights to Everest's approximately $1.8 billion retail insurance portfolio — ultimately closed at a reduced purchase price of approximately $270 million versus the initial $300 million, reflecting improved deal terms — is a structurally attractive premium growth mechanism. Unlike organic new business development, renewal rights acquisitions allow AIG to underwrite a known book of business at existing pricing levels, with the ability to apply its own terms and discipline at renewal. The 75% retention rate achieved on the first $180 million of gross premiums written converted in January 2026 validates the portfolio quality thesis. Management has guided that the Everest conversion will drive a 10 basis point combined ratio benefit over the conversion period, and the full $1.8 billion portfolio at 75%+ retention represents approximately $1.35 billion of incremental net premiums written. Layered onto a base of $17.4 billion in FY2025 NPW, this single transaction accounts for roughly 8 percentage points of the guided low-to-mid-teens NPW growth in FY2026. Critically, the economics are front-loaded: the $270 million purchase price is already sunk, the distribution relationships are inherited, and loss experience on a mature book is more predictable than new business. This is premium volume with significantly below-average acquisition cost per dollar of NPW. As of the February 2026 earnings call, management characterised the year as "already off to a very strong start," which combined with the known conversion schedule provides unusually high visibility into FY2026 revenue. We forecast $30.4 billion in total revenue in FY2026, net income of $4.6 billion, and EPS of $9.85 — the EPS step-change from $5.43 in FY2025 reflects both earnings growth and the compounding effect of share count reduction. 3. **Buyback arithmetic is the central EPS driver and the market is systematically underweighting it** AIG's $3.5–5 billion annual buyback commitment against a current market capitalisation of approximately $43 billion represents a buyback yield of 8–12% per annum. At the midpoint of $4.25 billion and a share price of $77, this implies retirement of roughly 55 million shares per year from an estimated diluted count of approximately 470 million entering FY2026. Share count reduction of 8–10% per year mechanically amplifies EPS growth by the same percentage above and beyond net income growth. The arithmetic is compelling: our forecast net income grows from $3.1 billion in FY2025 to $6.2 billion in FY2029, a doubling over four years. But EPS grows from $5.43 to $27.05 over the same period — a nearly five-fold increase — because the denominator is shrinking aggressively each year. By FY2029, we estimate the diluted share count will have fallen to approximately 230 million, less than half the current level. This is not financial engineering in a pejorative sense; it is rational capital allocation by a company that generates $3.5–4.0 billion in free cash flow annually and cannot deploy that capital more value-creatively than retiring its own shares at 8x earnings. The market appears to be valuing AIG on a trailing or current-year P/E basis without capitalising the forward share count trajectory. A static P/E multiple applied to a rapidly shrinking share count is a systematic mispricing of the time value of that capital return. Investors who hold for three to four years will own a materially larger percentage of a materially higher earnings base at a de minimis additional cost. 4. **Underwriting quality improvements are structural, not cyclical, and are approaching peer benchmarks** AIG's combined ratio improvement trajectory — from the high-90s during the portfolio remediation era to 91.3% in FY2025 general insurance — reflects genuine underlying improvement in portfolio composition, not merely a favourable catastrophe year. North America commercial retention of 89% in admitted lines and 87% internationally indicates that pricing discipline has not caused adverse selection or volume leakage, which historically has been the canary in the coal mine for insurers that improve margins by shedding customers. The loss ratio improvement reflects several structural changes: the exit of underperforming lines during the Peter Zaffino-led remediation, shift toward higher-quality commercial and specialty risks, tightened reinsurance structures with defended attachment points, and improved claims handling. Management's stated philosophy — "once you give it up, you don't get it back" on attachment point discipline — reflects an institutionalised risk culture that is qualitatively different from the pre-2017 AIG. Commercial lines pricing remains firm across property, casualty, and financial lines in North America, providing a tailwind to the loss ratio that does not require market share gains. International commercial benefits from similar pricing dynamics in marine, specialty, and casualty lines. Our forecast assumes the combined ratio continues to grind toward 90% by FY2027–2028, which would represent best-in-class performance comparable to Chubb or Travelers — a peer group that trades at 16–18x earnings versus AIG's current 14x. 5. **Valuation gap versus peers is wide, and the catalysts for closure are scheduled, not speculative** At $77.02 and FY2026 EPS of $9.85, AIG trades at 7.8x forward earnings. Chubb trades at approximately 14x, Travelers at 13x, Hartford Financial at 12x, and W.R. Berkley at 15x. The valuation discount reflects residual scepticism about AIG's execution credibility, historical reserve volatility, and the complexity of the post-Corebridge transition. These are legitimate concerns, but they are backwards-looking. The catalysts for multiple re-rating are not speculative — they are already underway and have scheduled milestones. Everest conversion is progressing quarter by quarter with disclosed retention metrics. Expense ratio improvement has management guidance with a specific year target (sub-30% by 2027). Share count reduction is mechanically executing through existing buyback authorisations. FY2025 results demonstrated that the underlying earnings power is real: $3.1 billion of net income on a $17.4 billion NPW base is a 17.8% net margin, above the level at which any rational peer comparison would justify a sub-8x multiple. Our price target of $138 for FY2026 applies 14x to $9.85 EPS — a multiple that does not require AIG to be valued as a best-in-class insurer, only as a competent large-cap diversified insurer. The path to $200+ by FY2028 at the same multiple requires only that management executes on publicly stated guidance, which FY2025 results have already partially validated.

Risks

1. **Reserve development and legacy liability exposure** AIG carries legacy long-tail liabilities across casualty, financial lines, and international segments that could produce adverse reserve development if loss trends — particularly in social inflation-sensitive lines such as directors and officers, general liability, and excess casualty — deteriorate beyond current actuarial assumptions. The company underwent significant reserve strengthening actions between 2017 and 2022; however, long-tail casualty lines have multi-year development periods and FY2025 favourable development does not immunise against future deterioration. A $500 million adverse reserve development event — plausible in a scenario of elevated US litigation costs or a systemic casualty trend emergence — would reduce FY2026 net income by approximately 11% and compress EPS by a similar magnitude. Reserve adequacy is not directly observable by external analysts and represents the most consequential information asymmetry risk in insurance investing. 2. **Catastrophe severity could overwhelm reinsurance structures** AIG maintains attachment point discipline in its reinsurance programme, but the company retains meaningful net catastrophe exposure in North America property, international property, and global personal lines. A severe hurricane season, California wildfire event above historical norms, or international catastrophe aggregate could produce losses materially above management's modelled probable maximum loss. FY2024 included elevated catastrophe losses; FY2025 saw more normalised experience. A repeat of an above-average catastrophe year in FY2026 — which is already benefiting from Everest conversion growth in property lines — could compress the combined ratio by 3–5 points, reducing net income by $500 million to $850 million depending on event severity and reinsurance recovery timing. 3. **Everest portfolio conversion retention deteriorating below 75%** The Everest portfolio conversion is sized at approximately $1.8 billion of gross premiums written, and our FY2026 revenue and EPS forecasts assume continued strong retention in the 70–80% range through the conversion period. If broker relationships do not transfer as expected, if Everest aggressively re-quotes the renewing business, or if pricing on the converted book does not meet AIG's underwriting standards, actual retained premium could fall materially short of projections. A scenario in which retention falls to 50% would reduce incremental NPW contribution by approximately $450 million versus our base case, compressing FY2026 NPW growth from mid-teens toward high-single-digits and reducing net income by an estimated $45–90 million depending on the underwriting margin on converted business. 4. **Reinsurance cost inflation reducing underwriting margins** AIG is a significant buyer of catastrophe and per-risk reinsurance, and the global reinsurance market remains in a firming cycle following elevated losses in 2021–2023. While AIG has held firm on attachment points — which partially insulates it from frequency losses — severity events could prompt reinsurers to reprice or restrict capacity at renewal. A 10% increase in reinsurance premiums ceded on an estimated $3–4 billion ceded premium base would represent $300–400 million of additional cost annually, directly reducing underwriting income. Management's stance that attachment point discipline is non-negotiable is strategically sound but means AIG cannot easily substitute cheaper reinsurance if the market hardens at the severity layer. 5. **Capital return pace constrained by rating agency or regulatory capital requirements** Our EPS forecasts are materially dependent on $3.5–5 billion of annual share buybacks sustaining for four consecutive years. This requires AIG to maintain robust regulatory capital ratios across its domestic and international insurance subsidiaries, satisfy AM Best and S&P rating agency capital models, and generate sufficient holding company liquidity through subsidiary dividends. If catastrophe losses, reserve development, or investment portfolio stress (particularly in the $80 billion fixed income portfolio in a rising rate or credit spread widening scenario) reduce subsidiary dividend capacity, the holding company buyback pace could be curtailed without public announcement until it is already embedded in a quarterly result. Net debt is forecast to increase from $1.6 billion in FY2026 to $7.6 billion by FY2029, partially funding buybacks through leverage — this trajectory increases financial risk and constrains future capital flexibility. 6. **Investment portfolio mark-to-market and credit risk** AIG's $80 billion investment portfolio is predominantly fixed income and generates substantial net investment income that underpins profitability. A sustained rise in credit spreads, a recession-driven increase in corporate default rates, or a structural shift in the interest rate environment could produce both mark-to-market losses affecting book value and a deterioration in investment income. The portfolio also has some exposure to alternatives and private credit, which carry valuation uncertainty in stress scenarios. While investment losses do not necessarily impair operating earnings in the short term under insurance accounting, significant unrealised losses reduce tangible book value per share — a metric that rating agencies, regulators, and institutional investors use to assess insurer solvency — and could constrain the buyback programme at precisely the moment when the share price would make buybacks most value-accretive.
