SoftBank's Yahoo Japan, one of Japan's top internet firms, confirmed it is in talks to merge with Line, a $27 billion union that would bring the messaging app operator under the SoftBank umbrella in a major tech shake-up.
Yahoo Japan, which last month changed its name to Z Holdings, said on Thursday discussions were underway with Line but nothing had been decided. SoftBank, which owns almost half of Z Holdings, also acknowledged the talks.
Shares in Z Holdings, which had a stock market value of about $17 billion at Wednesday's close, jumped 16% in Thursday trading.
Shares in Line, which is valued at about $10 billion, were untraded with a glut of buy orders.
Sources told Reuters the previous day a deal was likely by month-end and could see SoftBank and Line's parent Naver form a 50/50 venture that would control Z Holdings, which would in turn operate Line and Yahoo.
Line said in a statement it was true it is considering ways to improve its corporate value but nothing had been decided.
A deal would bring together the operators of two of Japan's biggest QR code payment apps as the country belatedly shifts to cashless payments. SoftBank's PayPay recently hit 19 million users through aggressive marketing, while Line Pay can tap the 82 million Japanese users of the Line app.
Line, which last year sold a majority stake in its mobile unit to SoftBank, has reported three consecutive quarters of operating losses as the company tries to jump-start growth.
Z Holdings made a move in September to take control of fashion e-tailer Zozo in a $3.7 billion deal, as it bulks up against rivals such as Amazon.com.
Deal making by SoftBank, controlled by tech conglomerate SoftBank Group, comes despite the weak performance of the technology bets of its parent, which recorded an $8.9 billion operating loss in the second quarter.
The group's first quarterly loss in 14 years followed a collapse in the value of its investment in office-sharing firm WeWork as investors have turned skeptical about the path to profitability at cash-burning startups.
