AM Best Affirms Credit Ratings of Grupo Aserta S.A.P.I. de C.V. and Its Main Subsidiaries

MEXICO CITY--(BUSINESS WIRE)--AM Best has affirmed the Long-Term Issuer Credit Rating (Long-Term ICR) of “bbb” (Good) and the Mexico’s National Scale Rating (NSR) of “aa.MX” (Superior) of Grupo Aserta S.A.P.I. de C.V. (GA). Concurrently, AM Best has affirmed the Financial Strength Rating of A (Excellent), the Long-Term ICR of “a” (Excellent) and the NSR of “aaa.MX” (Exceptional) of Aseguradora Insurgentes, S.A. de C.V. (AISA), and its sister company, Aseguradora Aserta, S.A. de C.V. (Aserta), which are the main subsidiaries of GA. The outlook of these Credit Ratings (ratings) is stable. All companies are domiciled in Mexico City, Mexico.

These ratings reflect AISA and Aserta’s consolidated balance sheet strength, which AM Best assesses at the strongest level, as well as their strong operating performance, neutral business profile and appropriate enterprise risk management (ERM).

The stable outlooks reflect AM Best’s expectation that GA’s balance sheet strength assessment will remain at the strongest range while ongoing strategic initiatives help further diversify revenues and net income.

In January 2017, AISA and Aserta were authorized to operate as insurance entities under a surety insurance (seguro de caución) license, and changed their names from Afianzadora Insurgentes, S.A. de C.V. and Afianzadora Aserta, S.A. de C.V., respectively. In July 2018, the companies received approval to underwrite surety, surety insurance and credit insurance. As of December 2024, most of the business volume corresponding to surety insurance was issued primarily through Aserta’s Americas office.

The ratings also reflect the group’s leading position in Mexico’s surety market, historically good consolidated operating performance throughout the market cycle and its seasoned management team. In addition, the ratings recognize the companies’ affiliation as larger members of GA.

The group’s positive rating factors are driven by its surety companies’ solid surplus positions and sound underwriting practices, in conjunction with reinsurance programs placed among highly rated reinsurance counterparties. In addition, the geographic expansion through Aserta’s Spain branch has been an important driver of profitability and growth. For the future, AM Best will monitor the impact of the separation of Controladora Aserta Europa SL from the group. GA has invested in innovative initiatives that have differentiated it from competitors and added value for its clients.

As of September 2025, Mexico’s surety market continues to show hardening conditions amid overall signs of growth, specifically in infrastructure projects. The companies have reported positive bottom-line results for the past 10 years, with a stable return on gross written premium across different business cycles and adequate profitability metrics in comparison with other Mexico surety writers. At the same time, GA has taken measures to counter potentially adverse market conditions and diversified its revenue further by increasing its international presence and by taking advantage of new surety insurance opportunities. Going forward, the company expects to continue expanding into America as global business through its registration in other territories leveraging its innovative products and distribution channels. AM Best expects AISA and Aserta to maintain their strong market share and meet expansion targets while maintaining supportive risk-adjusted capitalization levels, as measured by Best’s Capital Adequacy Ratio (BCAR).

GA is well-protected by its reinsurance program and its contingency reserves. The company’s appropriate ERM framework has allowed it to manage exposures effectively and make efficient use of its capital to improve its solvency. Negative rating actions could result from adverse scenarios in the surety market that translate to material deterioration of the company’s operating performance to levels that AM Best considers non-supportive of the current ratings.

Although unlikely in the short term, positive rating actions could take place for GA’s subsidiaries if the companies continue to strengthen their capital base and financial strength while successfully implementing a geographic diversification strategy.
