Mosaic’s specialty casualty business provides tailored solutions for third-party liability exposures that require deeper technical analysis, specialist judgment, and meaningful capacity. Spanning excess casualty and energy, our expertise addresses risks ranging from bodily injury and property damage to complex operational and industry-specific exposures, often across multiple jurisdictions.

We combine detailed exposure analysis with a clear understanding of how losses can develop over time. Across energy, transportation, construction, industrial manufacturing, hospitality, and utilities, our underwriters work closely with brokers and insureds to navigate complex risks and structure responsive solutions. Disciplined underwriting, proactive claims engagement, and long-term partnerships underpin our approach.
