Big Short' investor Steve Eisman backs AIG as analyst calls insurer 'really, really cheap

Steve Eisman, the investor known from "The Big Short", has disclosed that he owns shares in American International Group. His comments came during a podcast discussion with Cantor Fitzgerald analyst Ryan Tunis, who rates AIG as "really, really cheap". Tunis upgraded AIG to Overweight in July with a price target of $92, later trimmed to $90. This implies approximately 18% upside from the stock's recent $76.21 close, near its book value of $77.39 per share. The analyst highlighted AIG's restructuring efforts and improved underwriting operations. The insurer reported $686 million in second-quarter underwriting income, up 10% year-on-year. However, Tunis cautioned that the commercial insurance market is softening after seven years of strong pricing power. He noted that AIG's heavy exposure to large corporate accounts could face pressure as competitors chase business on price.

AIG launches parametric cyber cover for US cloud outage risks with Parametrix

American International Group has launched a parametric cloud outage cyber insurance product for US clients, developed with Parametrix. The solution covers business interruption risks from third-party cloud and software service provider outages. Claims are based on predefined outage triggers and external monitoring data, designed to accelerate the claims process. The product targets US businesses heavily reliant on cloud infrastructure and software platforms. AIG, a US insurance company with a market capitalisation of approximately $39.8 billion, aims to compete for larger cyber and professional liability programmes where cloud downtime recovery is crucial. The launch aligns with the company's focus on digitalisation and specialised products. Investors should monitor upcoming quarterly disclosures for cyber or parametric premium volumes and client uptake commentary to assess the product's market traction.

AIG Q2 revenue misses forecasts at $7.11B despite profit beat

AIG reported second-quarter revenue of $7.11 billion, missing analyst estimates of $7.27 billion despite 3.9% year-on-year growth. However, the insurance giant's non-GAAP earnings per share of $2 beat expectations by 3.7%. The revenue shortfall stemmed from deliberate contraction in North American property portfolios as management prioritised risk-adjusted returns amid increasing market competition. CEO Eric Andersen highlighted strong performance in accident and health products and high net worth personal lines. AIG is deploying artificial intelligence platforms to improve underwriting and claims processing whilst targeting expense ratio reductions below 30% by 2027. The company announced an acquisition of Everest Insurance's Colombia operations to expand in Latin American markets. Management maintains focus on balancing growth with profitability through disciplined underwriting and selective portfolio expansion.

AIG shares slip 9% YTD despite generating $3.2B net income, trading 10.9% below fair value

American International Group (AIG) shares currently trade at $77.05, down 9% year to date despite rising 3% over the past month. The stock has delivered a 50.4% total shareholder return over three years. The most popular valuation narrative suggests AIG is 10.9% undervalued, with a fair value of $86.45. This assessment relies on the company's digitalisation and artificial intelligence initiatives across underwriting and claims, which could enhance operational efficiency and margins. AIG generated $26.7 billion in revenue and $3.2 billion in net income. However, the stock trades at 12.9 times earnings, above both the US insurance industry average of 11.3 times and its own fair ratio of 12.7 times. Key risks include climate exposure and claims inflation potentially pressuring margins.
