Markel strengthens Malaysia platform with dedicated Casualty underwriting capability, appointing Senior Underwriter Tan Weng Fatt

Kuala Lumpur, 9 July, 2026 — Markel Insurance, the insurance operations within Markel Group Inc. (NYSE: MKL), today welcomed Tan Weng Fatt to the business as Senior Underwriter - Casualty, Malaysia, with immediate effect.

Based in Kuala Lumpur, Tan will lead Markel's Casualty offering, driving local underwriting execution, strengthening relationships with brokers and cedants and supporting the development of a diversified and disciplined portfolio. He will also oversee the Marine Energy Liability offering, collaborating closely with the team led by Alicia Leong, Head of Marine and Energy Liabilities, Singapore, as well as regional and global underwriting teams in London.

Tan brings 16 years of insurance and reinsurance experience, with deep expertise in liability underwriting and a strong track record across casualty insurance for the oil and gas, manufacturing and construction industries. He joins from Berjaya Sompo Insurance Berhad, where he was Head of Liability, Commercial Underwriting. Prior to this, he held senior casualty underwriting roles at Chubb Insurance Malaysia Berhad and Liberty Specialty Markets Singapore Pte Ltd, Labuan Branch, where he was responsible for casualty business across Malaysia and wider regional portfolios.

This investment forms part of Markel's longer-term strategy to create a more balanced and diversified portfolio in Malaysia, complementing its existing capabilities across Marine, Energy, Professional and Financial Risks and Cyber. It also reflects Markel's broader Asia Pacific strategy to invest in talent, empower local underwriting decision-making and expand core specialty lines in markets where the business sees sustainable long-term opportunity.

Jasminder Kaur, Country Head, Markel Malaysia, said: “Weng Fatt's appointment represents an important step in the continued evolution of our Malaysian platform. As we build out our specialty capabilities, establishing dedicated Casualty underwriting on the ground, with Marine Energy Liability alongside it, is a natural progression for the business.

“Malaysia is an increasingly important market in Asia Pacific and this investment reflects both the opportunity we see and our commitment to building a disciplined, long-term presence. Weng Fatt brings valuable technical expertise, market insight and strong broker relationships and we are excited about the role he will play in shaping this next phase of growth.”

Sucheng Chang, Managing Director – Asia Pacific, said: “Malaysia is a priority growth market for Markel in Asia Pacific and Weng Fatt’s appointment is a clear signal of our commitment.

“Malaysia's energy sector, infrastructure pipeline and expanding industrial base are driving real demand for sophisticated Casualty and Marine Energy Liability solutions. By backing senior local talent and building these capabilities on the ground, we can underwrite these risks with the discipline, technical depth and proximity our brokers and clients have come to expect from us.”
