Facebook’s stalled attempt to buy Twitter, it seems, hasn’t dampened its appetite for acquisitions.

Peter Thiel, one of the social networking company’s largest investors and a director on its board, told BusinessWeek that Facebook is still on the lookout of deals.

“We’re still focusing on growing as much as possible,” he told the publication.

As for the failed Twitter deal, Mr. Thiel told BusinessWeek that talks to buy the microblogging service fell apart due to disagreements over over price and structure.

“It became pretty clear it wasn’t going to happen,” Mr. Thiel, who runs hedge fund Clarium Capital, told the magazine. “The deal would have to be done with Facebook stock. And then you have to figure out how much the stock is worth.”

Last fall, reports surfaced that Facebook offered Twitter 3.33 percent of its stock, which it had determined was worth $500 million, based on a $15 billion valuation for Facebook that was set when Microsoft invested in the company a year ago.

But, BusinessWeek said, Twitter balked at the Facebook valuation, knowing that Facebook was letting employees sell stock on the secondary market at company valuations ranging from $2 billion to $4 billion.

“We said it’s not worth it,” a person close to Twitter with knowledge of the negotiations told BusinessWeek. “Don’t treat us like children.”

In December, however, Twitter chief executive and co-founder Evan Williams, didn’t rule out that a deal could be rekindled some time in the future.

“We explored it, as we should. We took it seriously,” Mr. Williams at the time. “It definitely made sense – the strategy we talked about with them – but it wasn’t the right time.”
