AVAST Software s.r.o. has hired Rothschild to prepare for a share sale, four sources familiar with the matter told Reuters. CVC Capital Partners could seek an initial public offering for Avast in the first half of 2018, if market conditions allow, two of the sources said. CVC hired Rothschild, the sources said, adding Rothschild will carry out the preliminary work for the deal which includes the selection of global coordinators and book runners. CVC and Rothschild declined to comment.
