Tim Perry was previously Co-Head of Credit Suisse's Oil and Gas Group in the Americas region. He joined Credit Suisse in 1999 and has led the bank's Exploration and Production (E&P) franchise, where the bank achieved a #1 position in 2015. Throughout the course of his 25-year career in investment banking, Perry has provided capital raising and strategic advice to numerous leading private and public companies in the Oil and Gas sector. He will continue to be based in Houston.

Jim Amine, CEO of Investment Banking and Capital Markets, said: "Our Oil and Gas business has consistently been one of our leading franchises. Tim has played a critical role in strengthening the bank's leadership position in the E&P sector and I have great confidence that Osmar and Tim will continue to build on this success and drive this important business forward."

Credit Suisse has been the leading bank in equity issuance in the E&P industry in the United States, having participated in 45 E&P follow-on offerings since January 2015, 38 of them in a lead-left capacity. The bank also led Extraction Oil & Gas's Initial Public Offering (IPO), the first IPO in the E&P industry since October 2014. In addition, Credit Suisse has advised on some of the Oil and Gas sector's most transformational M&A transactions in recent years, including Cameron's sale to Schlumberger, Range Resources acquisition of Memorial Resources Development, and Enbridge's acquisition of Spectra.
