Shearman & Sterling LLP fields 'an elite team, confidently led by David Higbee', which 'sees around corners that other outfits just can't seem to'. New York's Jessica Delbaum 'is very proactive in her approach' and Ben Gris - who recently joined from the FTC - 'has a unique first-hand merger litigation experience and knows the regulators inside out'. The team advised LyondellBasell on its acquisition of high-performance material supplier A. Shulman, and assisted Glatfelter - led by Delbaum - with its acquisition of Georgie-Pacific's European nonwoven business. Also notable is of counsel Wayne Collins, who splits his time between New York and Washington DC, and is 'the rare kind of lawyer who is at home with regulators, CEOs, economists and can communicate on every level'. Gris and Higbee are based in Washington DC.
