For the first time in the Merco survey's history, a single company topped the list in all three categories.

This triple honour underscoring Inditex’s hard work is also reflected in the report’s list of Spain’s corporate executives, with Inditex founder Amancio Ortega and current chairman Pablo Isla ranked No. 1 and No. 4, respectively.

The Merco report, whose results were analysed by consulting firm KPMG to verify their independence, assesses several benchmarks, including earnings, the quality of each company's goods or services, in-house reputation, ethics, international scope and innovation.

To gauge each of these areas, Merco polled more than 12,000 people, including 1,503 executives, approximately 750 experts in business administration and nearly 9,000 workers.
