We are delighted to share that ABNR had the privilege of advising OSL Group Limited (“OSL”), one of Asia’s leading digital financial asset platforms listed on the Hong Kong Stock Exchange, on its successful acquisition of KoinSayang.

The transaction was co-led by Partners Chandrawati Dewi and Monic Devina, supported by Senior Associate Meitiara Bakrie, and Associates Ruth Mendrofa, Marshel Miyata, Gladyne Mesepy, Atika Fajrina, Ershad Murtadho, Edmund Khovey, Alda Eunique, and Ksatria Abimanyu.
