ASC Law Office continues to stand out for its regulatory command of Turkey’s hydroelectric, thermal, wind, solar and natural gas sectors, advising on complex, multi-layered mandates that require navigation of dense regulatory frameworks. The team is increasingly active on the financing side, recently steering major syndicated loan facilities, IPO preparations and large-scale debt restructurings for energy companies. At the helm, Okan Beygo and Levent Yetkil bring significant project finance capability, with Yetkil offering particular experience in EPC-related issues, while Fulya Sert Topçu remains a central figure on the firm’s most significant financing transactions.
