Original research on Spanish corporate structure, computed over the official BORME registry publications: 3.2 million companies and 9.6 million filings since 2009. Every study publishes its methodology and its figures so they can be checked and cited.
Who sits on more than one board among Spain's 35 largest listed companies, and which companies a shared director links together.
205,077 capital operations show that governance change is registered in the same filing as the capital operation, and almost nowhere else.
Every study is computed over BORME, the official gazette of the Spanish commercial registry, processed from 2009 onwards. These are not official statistics nor registry certificates: they are independent analyses produced through automated processes and may contain errors or omissions. Each study states the date of its data and the methodological choices that affect its figures.
