AM Best Affirms Credit Ratings of Seguros El Potos?, S.A.

BY Business Wire | CORPORATE | 03:29 PM EDT

MEXICO CITY--(BUSINESS WIRE)-- AM Best has affirmed the Financial Strength Rating of A- (Excellent), the Long-Term Issuer Credit Rating of ?a-? (Excellent) and the Mexico National Scale Rating of ?aaa.MX? (Exceptional) of Seguros El Potos?, S.A. (El Potos?) (San Luis Potosi, Mexico). The outlook of these Credit Ratings (ratings) is stable.

The ratings reflect El Potos??s balance sheet strength, which AM Best assesses as very strong, as well as its adequate operating performance, neutral business profile and appropriate enterprise risk management (ERM).

El Potos? is a Mexico-based insurer underwriting property/casualty, life, and accident and sickness insurance. Founded in 1946, the company began operations in the fire insurance segment and expanded into automobile insurance in 1971. Over time, it has diversified into multiple lines of business. The company is majority-owned subsidiary of Seguros Atlas, S.A. (Atlas) and operates in a competitive market, with a market share of less than 1% based on gross written premiums (GWP) in 2025.

El Potos??s balance sheet strength is underpinned by its risk-adjusted capitalization, which is at the very strong level, as measured by Best?s Capital Adequacy Ratio (BCAR). The company?s capital base has historically benefited from its reinvestment of profits.

In 2025, earnings declined by 9% year-over-year, primarily driven by higher claims costs associated with the new value-added tax treatment in Mexico, which increased the cost of claims, particularly in the motor line, coupled with a slight increase in operating expenses. Additionally, El Potos??s investment performance has experienced some pressure due to declining interest rates, as the company?s portfolio is concentrated in Mexican fixed-income securities; however, it continues to help the company deliver positive bottom-line results. Despite these pressures, the very strong balance sheet strength assessment reflects AM Best?s view of the company?s prudent capital management, while supporting growth and maintaining divided payments.

El Potosi?s operating performance is assessed as adequate, supported by solid business generation, reflected in a 30% year-over-year increase in GWP and stable expense management. However, underwriting results remain under pressure, as evidenced by a combined ratio above 100%. Nonetheless, overall profitability continues to be supported by solid investment income and underwriting actions aimed at improving profitability quality and margins. Looking ahead, AM Best expects El Potosi to restore operating efficiency gradually, supported by prudent growth and sound portfolio management.

AM Best assesses El Potos??s business profile as neutral, primarily due to its significant reliance on the automobile line, which accounts for 54% of the total portfolio. Premiums are concentrated in Mexico; however, the company benefits from diversification across different states and maintains a mixed distribution channel strategy, which partially mitigates concentration risks.

El Potosi?s risk management framework follows a structured process centered on risk monitoring and is well integrated into its operations. The company adheres to ERM practices established by its holding company. Additionally, El Potosi maintains a comprehensive reinsurance program placed with highly rated counterparties. AM Best assesses the company?s ERM as appropriate.

Negative rating actions could occur if capital adequacy fails to keep pace with business growth, leading to a weakening in its balance sheet strength. Negative rating actions could also arise by a sustained deterioration in operating performance, particularly if underlying profitability weakens. Positive rating actions could occur if El Potos??s operating performance strengthens on a sustained basis, driven by stronger underwriting performance.

In general the bond market is volatile, and fixed income securities carry interest rate risk. (As interest rates rise, bond prices usually fall, and vice versa. This effect is usually more pronounced for longer-term securities.) Fixed income securities also carry inflation risk and credit and default risks for both issuers and counterparties. Unlike individual bonds, most bond funds do not have a maturity date, so avoiding losses caused by price volatility by holding them until maturity is not possible.

Lower-quality debt securities generally offer higher yields, but also involve greater risk of default or price changes due to potential changes in the credit quality of the issuer. Any fixed income security sold or redeemed prior to maturity may be subject to loss.
