Opera Software delayed the release of its quarterly results, amid speculation that the company may be an acquisition target.

Reports last week indicated that Chinese internet company Qihoo 360 may be looking at Opera, as a way to expand its presence beyond its home market.

TechCrunch also mooted that AOL may be interested in Opera, due to the Norwegian company’s recent moves into mobile advertising.

For its part, Opera said last year that it is reviewing its options, warning that 2015 revenue – initially scheduled to be announced today – was tracking below its expectations.

While this was initially due to be completed before the end of the year, the company subsequently said that it is “expected to conclude by the time Opera reports full-year 2015 results” – now.

In the meantime, the company has reorganised its operations in a way that will “entail a more appropriate group structure with regard to management, operations and strategic flexibility”, stating that its board “considers it to be important and beneficial for the further development of Opera to create a group structure allowing the business areas to be developed separately”.

However, it also said that this has “no direct connection with the ongoing strategic review process, other than that it gives additional flexibility with respect to future structural solution”.

Opera said its business comprises primarily of three activities: consumer, including its browser, performance and privacy apps; TV software; and mobile advertising.
