About Assured Guaranty Ltd

Assured Guaranty Ltd. (NYSE: AGO) is a leading financial guaranty insurer with a U.S.-focused franchise and an international footprint. Although the parent company is based in Hamilton, Bermuda, the group operates through subsidiaries that serve public finance and structured finance markets in the United States and abroad. Its core business is credit protection: the company insures scheduled principal and interest payments on bonds and other obligations, helping municipalities, infrastructure issuers, utilities, and structured-finance borrowers access the capital markets on more favorable terms. ([assuredguaranty.com](https://assuredguaranty.com/investor-information/by-company/assured-guaranty-ltd?utm_source=openai)) The company has a long operating history in the financial guaranty space and notes in its 2024 annual report that it entered its 40th year in business. Over time, Assured Guaranty evolved into one of the most recognized names in bond insurance, supported by conservative risk selection, a large insured portfolio, and a capital-management framework designed to preserve underwriting discipline while returning excess capital to shareholders. Its organizational structure includes insurance subsidiaries, a Bermuda-based reinsurance platform, and an asset-management component linked to Sound Point.

The company insures municipal general obligations, tax-backed debt, transportation and utility credits, infrastructure financings, housing-related bonds, and selected structured transactions such as subscription finance and pooled corporate business. Management highlighted in second-quarter 2025 results that U.S. municipal penetration remained strong, while the company also continued to write infrastructure business in the U.K. and European Union.

In its fourth-quarter and full-year 2025 earnings release, the company stated that it led the U.S. municipal bond insurance market in 2025 with 58.5% of new-issue insured par sold, and it also posted a sizable secondary-market presence. That leadership matters because it reinforces brand value, supports recurring fee and investment income, and creates operating leverage when municipal issuance volumes improve.

In 2025, Assured Guaranty reported strong quarterly results, rising book value per share and active share repurchases, while also maintaining a quarterly dividend. At year-end 2025, it reported approximately $1.0 billion of alternative investments, including CLO equity tranches and other specialty funds, which adds income potential but also introduces some mark-to-market volatility. In January 2026, the company expanded beyond its traditional guaranty model by acquiring Warwick Company (UK) Limited, the indirect owner of Assured Life Reinsurance Ltd., signaling a strategic entry into life and annuity reinsurance.
