AIG triples underwriting income

Insurance earnings can look dull until one number jumps off the page. For AIG this week, that number was underwriting income — the profit from actually writing insurance before investment gains muddy the picture. In the first quarter of 2026, AIG’s General Insurance unit posted $774 million of underwriting income, up 219% from $243 million a year earlier. That is the cleanest sign yet that the company’s multiyear cleanup is turning into a margin story, not just a restructuring story. ### What does “underwriting income” actually mean? It is the core insurance business stripped to basics. An insurer collects premiums, pays claims, and covers operating costs. If premiums are priced well enough, the company makes an underwriting profit. If not, it can still look fine for a while because collecting risk and charging enough for it. ### Why was AIG’s quarter so much better? Three things moved at once. Catastrophe losses were lower. Current accident-year underwriting got better. And AIG booked higher favorable prior-year development — basically, old claims reserves turned out to be more than enough. That mix pushed General Insurance underwriting income to $774 million and helped adjusted pretax income rise 65% to about $1.5 billion. ### Why is the combined ratio the real tell? Because it shows whether the insurance engine is running efficiently. A combined ratio under 100% means the insurer is making money on underwriting. AIG’s General Insurance combined ratio improved to 87.3% from 95.8% a year earlier — an 850-basis-point swing shows the current book itself is healthier. ### Did AIG grow, or just get stricter? Both. Net premiums written in General Insurance rose 24% year over year on a reported basis, or 18% in constant currency, to $5.6 billion. Gross premiums written topped $10 billion, up 11%, with Global Commercial up 21% in constant currency and Global Personal up 11%. So this was not a quarter where AIG shrank its way to prettier margins. It grew and got more profitable at the same time. ### Why is that hard in insurance? Because pricing usually gets weaker when competition heats up. Commercial insurance has been moving into a softer market in several lines, which means carriers have to fight harder to keep business. The easy trap is to hold volume by accepting worse terms. AIG is arguing its quarter stands out. ### Is there anything less impressive under the hood? Yes — not every line moved in the same direction, and some of the jump came from lower catastrophe losses and favorable reserve development, which can bounce around quarter to quarter. Net investment income also fell 36% year over year to $712 million, which you would automatically annualize. ### What is AIG trying to prove now? That the post-breakup, post-portfolio-pruning AIG can be a consistently high-quality property-and-casualty insurer. The company already cleared $2 billion of annual underwriting income in 2025 for the
