Warner Music said its stock would start trading Wednesday at $25 per share and raise more than $1.9 billion in its hotly awaited IPO. The recording company increased the size of the deal to 77 million shares from the 70 million it had announced initially. Access Industries, a group of investors headed by billionaire Len Blavatnik, which acquired Warner Music for $3.3 billion in 2011, will retain its majority stake. The company will trade on the NASDAQ as WMG. It had set a price range of $23 to $26 for its shares. vog/dw/jh
