Homburger and Lenz&Staehelin in Alpiq arbitration proceeding

Alpiq and Bouygues Construction initiated arbitration proceedings against each other in 2019 to resolve their disputes regarding the post-closing purchase price adjustment and alleged breaches of representations and warranties, with a total amount in dispute of approximately CHF 320 m. The matter was placed before a Swiss arbitral tribunal constituted under the Swiss Rules of International Arbitration comprising Prof. Sébastien Besson (Chairperson), Dr. Roberto Dallafior and Dr. Urs Weber-Stecher. It involved the analysis of complex accounting and valuation issues. On December 22, 2020, Alpiq announced that the parties had reached a settlement under which Alpiq agreed to refund CHF 54.5 m to Bouygues Construction.
