Houston energy dealmaker Stephen Trauber has been tapped as chairman and global head of the energy and clean technology business at publicly traded investment bank Moelis & Co.

In 2010, The Wall Street Journal called Trauber “one of the best-connected energy bankers in Houston.”

Trauber comes to New York City-based Moelis from Citi, where he recently retired as vice chairman and global co-head of natural resources and clean energy transition. Before that, he was vice chairman and global head of energy at UBS Investment Bank, where he worked with Ken Moelis, who’s now chairman and CEO of Moelis.

“The global energy ecosystem is undergoing major consolidation and change,” Trauber says in a Moelis news release. “I look forward to actively participating in its strategic evolution and working with so many of our clients that are evaluating how best to create value during this period of transformation.”

In conjunction with Trauber’s hiring, Guggenheim Securities executives Muhammad Laghari and Alexander Burpee are joining Moelis as managing directors in Houston. They’ll work with upstream and midstream oil and gas clients. Laghari and Burpee previously were colleagues of Trauber at Citi.

During his career, Trauber has advised on more than $700 billion in energy deals, including mergers, acquisitions, and IPOs. Among the industry heavyweights involved in those deals were BP, Halliburton, Kinder Morgan, Nabors, Occidental Petroleum, Schlumberger, Shell, and Weatherford International.

“Steve is a recognized leader in the industry who has played a key role in many of the energy sector’s landmark transactions,” says Navid Mahmoodzadegan, co-founder and co-president of Moelis.

Three years ago, Trauber made waves when Spring-based ExxonMobil

rejected his pitch “to commit to a target for net-zero emissions even after shareholders staged a revolt over the company’s climate policy,” Bloomberg reported at the time.

Last year, Trauber joined the board of directors of Houston-based NEXT Renewable Fuels, the board of directors of Houston-based ASEAN Energy, and the M&A and transactions advisory board of London-based professional services giant Aon.

The three new hires at Moelis follow the September 2023 launch of its Clean Technology Group. Arash Nazhad of Houston is co-leader of the group.
