Mercury Insurance is modernizing its Texas commercial auto segment by shifting toward a highly segmented, data-driven pricing model. While the company identified a technical need for an 8.2% increase, they have opted for a more moderate 4.5% overall rate adjustment.

This change takes effect for new business on May 27, 2026, and for renewals on August 15, 2026, impacting 5,161 policyholders and approximately $61.6 million in written premium.

The update replaces legacy manuals with a structured, factor-based rating framework where premiums are calculated using a layered approach. This model incorporates operational data such as years in business and territory, behavioral metrics like driver scores and prior loss experience, and a significant emphasis on telematics participation and vehicle safety features.

By keeping the rate hike at nearly half of the indicated need, Mercury is leveraging granular data to remain competitive in the Texas market while improving loss ratios through precise risk segmentation.

Ultimately, while most Texas business owners will see moderate premium increases, those with strong safety scores and high telematics adoption are likely to find the most favorable pricing under this modernized framework.
