The transition will connect local clients to the full Marsh portfolio, enabling a transversal approach across risk, reinsurance, capital, people, investments, and management consulting.

Marsh operates publicly on the New York Stock Exchange, serves 130 countries, employs over 90,000 professionals, and generates annual revenue above $24 billion.

The alignment is designed to strengthen scale and analytical capabilities to meet global market challenges, with leadership highlighting the value of specialized data across health, benefits, pensions, and remuneration.

All business lines will be consolidated under a single corporate identity, with Mercer focusing on investment strategy, work organization, and managing benefits, health, and corporate pensions.

Mercer will operate under the Marsh brand starting September 1, 2026, marking the completion of the integration announced in October 2025.

Marsh’s global footprint spans risk and insurance, reinsurance and capital solutions, people and investments, and management consulting.

In Portugal, the transition tightens the integration between human resources consulting and other Marsh competencies to deliver integrated solutions for demanding corporate structures.
