The rumours have been confirmed - Hewlett-Packard is in talks to buy the information technology provider Electronic Data Systems or EDS.
The Wall Street Journal reported that the two companies were close to a deal and suggested that EDS may be priced between $12bn (£6.1bn) and $13bn.
The deal has now been confirmed but not the price tag.
However, the news has had an immediate impact on EDS' shares, which rose 27.9% on the day of the announcement.
HP said in a statement: "HP today confirmed that it is engaged in advanced discussions with Electronic Data Systems Corporation regarding a possible business combination involving the two companies".
Analysts are proposing that the deal is part of a bid by HP to become a big IT service provider.
Chad Hersh from Novarica told the Beeb: "HP has been trying to promote themselves as a major services organization over the past few years".
"This will certainly help them with that."
