Compañía Española de Petróleos, S.A.U. (CEPSA) is seeking financing. Mubadala Investment Company pushes ahead with an initial public offering for CEPSA, in what could be the largest such deal in a decade. CEPSA could announce the IPO as early as next week, pending final approval from the emirate’s rulers, the people said. CEPSA could raise about €3 billion ($3.5 billion) from selling a portion of its shares, people familiar with the plans said previously. Representatives for Mubadala and CEPSA declined to comment.
