Samsung allegedly offered an initial price in the range of $13.35 to $15.49 per BlackBerry share during the talks, Reuters said.
However, both Samsung and Blackberry denied the report in separate statements, with the Korean company describing the rumor as "groundless."
The Canadian company, for its part, said that it "has not engaged in discussions with Samsung with respect to any possible offer to purchase BlackBerry," according to the British daily The Telegraph.
"I don’t have any offers on my desk. If people would like to talk, I mean, talk is not an offer," Chen told Bloomberg at the time.
Last month, he said that he remains optimistic about his company’s future.
"We achieved a key milestone in our eight-quarter plan with positive cash flow. We also attained another important milestone in the release of our new enterprise software products and devices," Chen said.
Meanwhile, BlackBerry’s stock price jumped almost 30% to $12.60 immediately following news about Samsung’s alleged proposal.
Once one of the world's dominant smartphone manufacturers, Blackberry’s market share has slumped significantly in recent years amid tough competition from Samsung and Apple.
