Andrew CalderKirkland & Ellis LLP

Led from Houston by Anthony Speier and Andrew Calder, and also benefiting from a significant number of oil and gas focused transactional lawyers operating out of the firm’s nascent Dallas office, the ‘very responsive and knowledgeable’ team at Kirkland & Ellis LLP continues its upward trajectory in the sector, with clients benefiting not only from the firm’s longstanding M&A and finance expertise but also considerable sector knowledge. Although it is active across the value chain, the team is perhaps best-known for its upstream offering and has been involved in a significant amount of the recent  consolidation in the space, including its recent work for petroleum and natural gas exploration and production company Newfield Exploration on its $7.7bn merger with Encana Corporation. The firm is also able to leverage its longstanding private equity ties with heavy-hitters including KKR and the Carlyle Group which have seized on the relatively recent downturn in the sector to purchase assets at a discount with a view to realizing significant value through divestments in the years to come. ‘Knowledgeable, responsive and business-oriented’ partner David Castro has a flourishing reputation for M&A and capital works in the sector on behalf of public companies and private equity firms and is a key member of the team that also includes Sean WheelerWilliam Benitez and ‘seasoned professional Lindsey Jaquillard. All practitioners named are based out of Houston.

Andrew CalderKirkland & Ellis LLP

Combining market-leading private equity, capital markets, project finance and restructuring practice area strength with a heightened focus on mandates within the energy sector (precipitated by the opening of the firm’s office in Houston in 2014), Kirkland & Ellis LLP has successfully positioned itself as one of the leaders within the conventional power space. On the M&A front, the team is best-known for its work on behalf of private equity sponsors and infrastructure funds on buy and sell-side mandates throughout the value chain, including as it relates to the power and transmission, infrastructure and utilities sectors. The ‘excellent’ Houston-based partner Andrew Calder excels in handling corporate transactional and corporate governance mandates within the conventional power space. Calder heads up a team that also includes Rhett Van Syoc – whose wide-ranging energy and natural resources corporate practice includes a significant amount of private equity-driven domestic and international M&A within the power generation space. On the finance side, the ‘fantastic‘ Washington DC-based partner Rohit Chaudhry regularly advises lenders on power-related project development and acquisition finance mandates.
