Simpson Thacher & Bartlett LLP

Simpson Thacher & Bartlett LLP reinforces its eminent reputation as a go-to for leading global investment firms operating within the energy space, advising the likes of BlackRock, Blackstone, EQT and KKR on the purchase and sale of stakes in both conventional and renewable energy developers and producers. Alongside this work, the team has been active on the acquisition financing of wind and solar portfolios, capital markets work, and commercial agreements. Acting out of Houston and New York respectively, Breen Haire and Eli Hunt front the energy and infrastructure practice and take an active role guiding private equity funds and strategics through their M&A deals. Houston’s David Lieberman is sought out for his financing expertise, often counseling capital investors through debt instrument purchases as well as regularly overseeing acquisition financing mandates, while New York-based Brian Chisling’s practice spans M&A, joint ventures, financing and regulatory advice. Also based in New York, Martha Kammoun’s previous industry experience is an extra selling point for clients and is well-regarded for her work on energy transition and impact investments. Katy Lukaszewski and Gabriel Silva joined the practice in late 2023 from Sidley Austin LLP and Vinson & Elkins LLP respectively to add further traditional and renewable energy, as well as digital infrastructure expertise.
