WR Berkley (WRB) primarily sells its insurance products and services to other companies.

Due to the nature of the insurance industry, WR Berkley, like other insurance carriers, does not publicly disclose the names of its specific policyholders or "major customer companies." Insurance companies typically serve a vast and diverse base of clients across numerous industries, and specific customer relationships are considered proprietary and confidential information. Therefore, it is not possible to list specific names of customer companies.

Instead, WR Berkley's customer base can be characterized by the broad categories of businesses and industries it serves through its various underwriting units, which include:

• Small to Medium-sized Businesses (SMBs) and Large Enterprises: Companies across a wide array of industries, such as manufacturing, retail, professional services (e.g., legal, accounting, architectural), healthcare providers, construction companies, real estate firms, technology companies, and transportation and logistics businesses. WRB provides various commercial coverages including property, general liability, workers' compensation, commercial auto, and umbrella liability.
• Specialty and Niche Market Businesses: Companies operating in specific industries or facing unique risks that require specialized underwriting expertise. This often includes businesses in sectors like marine and aviation, energy, entertainment, financial institutions, and those requiring specific professional liability segments (e.g., directors and officers liability, errors and omissions).
• Businesses Requiring Excess and Surplus Lines Coverage: Companies with unusual, emerging, or high-hazard risks that are typically not covered by standard insurance markets. These can range from complex construction projects and unique manufacturing operations to new technological risks and challenging liability exposures.

The recent launch of Berkley Edge, a new business focused on professional liability and casualty insurance for small to mid-sized businesses and hard-to-place risks, further solidifies its commitment to expanding offerings in underserved segments of the E&S market.
2. Disciplined Underwriting and Rate Increases, particularly in Casualty Lines: The company consistently prioritizes disciplined rate-taking and selective underwriting. Management has indicated ongoing opportunities for adequate rate adjustments in casualty lines, driven by social and economic inflation. W. R. Berkley reported average rate increases, excluding workers' compensation, of approximately 7.6% in Q3 2025, 7.6% in Q2 2025, and 8.3% in Q1 2025.
3. Growth in Net Investment Income: W. R. Berkley anticipates continued growth in net investment income, supported by strong operating cash flows and favorable new money rates. The company's current reinvestment rates are consistently exceeding its average book yield, and its invested assets have expanded due to record operating cash flow, positioning it for further investment income growth. Net investment income increased by 9.4% in Q3 2025, 1.9% in Q2 2025, and 12.6% in Q1 2025.
4. Targeted Product and Geographic Expansion: Future growth will also be driven by selective product and geographic expansions, coupled with underwriting innovation and strategic capital deployment. The company is expanding its affluent personal lines by offering bespoke underwriting and ancillary services. W. R. Berkley is also focusing on targeted verticals such as construction, life sciences, cyber, marine, energy, and environmental lines with tailored products.
