BlackBerry’s share price rose dramatically after rumours of a takeover by Samsung surfaced, before just as quickly plunging back down to earth when denied by both companies.

The reports initially appeared in Reuters, who reported that Samsung had made an offer of up to $7.5 billion, or between $13.35 and $15.49 per share.

The Ontario-based smartphone company saw its stock price close at $12.59 yesterday, a rise of about 30%.

Reuters stood by the story as both BlackBerry and later, Samsung, issued statements of denial.

"Blackberry is aware of certain press reports published today with respect to a possible offer by Samsung to purchase BlackBerry," said a Blackberry statement to press.

"BlackBerry has not engaged in discussions with Samsung with respect to any possible offer to purchase BlackBerry. BlackBerry’s policy is not to comment on rumours or speculation, and accordingly it does not intend to comment further."

If an approach was made, there are several reasons why Samsung might be interested.

"The value of BlackBerry today is in solutions they could potentially deliver to enterprises. There is an opportunity within the enterprise market for Android devices; Samsung might be able to enhance their Android enterprise proposition," comments Roberta Cozza, Research Director at Gartner.

"Another potential value may be in patents. Another possible asset is that BlackBerry’s platform also has a positioning within the automotive industry, which could help Samsung getting into the Internet of Things and connected cars."
