Shearman & Sterling is advising China’s mobile social network platform Momo Inc on its deal to be taken private from the NASDAQ.

Momo, a chat app that helps users find friends based on locations and exchange messages, pictures and videos, received a buyout offer from its CEO Yan Tang in June, joining a string of Chinese tech companies that have delisted from the U.S. exchanges in recent months.

Tang and the buyout consortium already own about 47 percent of the company, with an aggregate voting power of about 84 percent. The offer values the company at $3.6 billion.

A Shearman & Sterling team led by Hong Kong partner Stephanie Tang is advising Momo on the deal. Conyers Dill & Pearman is representing the company on Cayman Islands law.

Momo announced in July that it formed a special committee to review the previously announced non-binding going private proposal.
