EMC has extended its US$1.8bn ($2.23 bn) all-cash offer for deduplication storage firm Data Domain until 10 July as lawsuits continue to muddy the waters.
The offer was originally meant to expire this Monday, 29 June, but EMC has bought more time, hoping the US Federal Trade Commission rules in its favour.
In a bidding acquisition war that brings back memories of HCL Infosystems' and Infosys Technologies' battle for Axon, EMC is competing with rival storage vendor NetApp for the acquisition of Data Domain.
But this war is messier. After EMC topped NetApp's offer of US$1.5bn by 20 per cent at the beginning of this month, it was trumped by a counteroffer from NetApp of US$1.9bn.
Data Domain rejected the EMC offer on 15 June, arguing it preferred NetApp's bid.
NetApp holds a 20 per cent stake in the company, compared to EMC's 0.5 per cent
Still EMC has insisted its offer, which works out at US$30 per share, is superior based on stock valuations, and has asked the Federal Trade Commission to examine the bid.
In a Friday statement, EMC chairman and chief executive, Joe Tucci, said: "We continue to anticipate a routine review by the FTC resulting in a timely regulatory approval."
"We look forward to the execution of the definitive agreement and closing of the transaction with EMC."
EMC is supported by legal firm Levi & Korsinsky, which has filed a class action suit against the directors of Data Domain, asserting that its acceptance of the NetApp bid was not in the best interest of shareholders.
The law firm argued NetApp had offered positions on its board to Data Domain executives.
In a particular, there are rumours that Data Domain chief executive Frank Slootman could be the next chief executive of NetApp.
If this is true it raises questions as to whether the sales process conducted by the board was fair and open.
Additionally, the Detroit Police and Fire Retirement System filed a separate lawsuit, arguing that Data Domain's board of directors had given NetApp an improper bidding advantage.
Data Domain is such a prize because of its success in the field of eliminating data duplication, which is becoming a major storage problem.
As backups are made more frequently, the amount of largely useless duplicated data grows.
