Salesforce.com Inc's chief executive, Marc Benioff, said he has ruled out bidding for Twitter Inc, a decision that appeased Salesforce's investors on Friday and raised questions about Twitter's future.

"In this case we've walked away. It wasn't the right fit for us," Benioff told the Financial Times in an interview, saying there were many reasons the fit was not right, including price and the culture of the company.

Salesforce.com Inc's (CRM.N) Chief Executive Marc Benioff said on Friday he had ruled out bidding for Twitter Inc (TWTR.N), a decision that appeased Salesforce's investors but raised questions about Twitter's future.

Salesforce, which is focused on cloud-based sales and marketing software, was the latest potential suitor to walk away from Twitter and appeared to bring the current round of acquisition talks to an end, sources familiar with the situation said.

That leaves the company and CEO Jack Dorsey to chart an independent course in the face of stagnant user growth, heavy losses and mounting competition from the likes of Instagram and Snapchat.

"In this case we've walked away. It wasn't the right fit for us," Benioff told the Financial Times in an interview, saying there were many reasons the fit was not right, including price and the culture of the company.

A spokeswoman for Salesforce confirmed the comments and said the company had nothing further to add. Twitter declined to comment.

Twitter's shares fell 5.7 per cent to US$16.77, while those of Salesforce rose 6.5 per cent to US$75.23.

A potential acquisition of Twitter had weighed on Salesforce's stock since news broke on Sept. 23 that it was vying for Twitter.

Twitter had planned to wrap up any sale discussions by the time it reports earnings at the end of October, and other companies that had expressed some interest in a deal - including Google (GOOG.O) and Walt Disney Co (DIS.N) - have also taken a pass, sources told Reuters earlier this week.

“It means they have to go it alone, at least for now,” said Jan Dawson, chief analyst with Jackdaw Research.

GROWTH STALLS

As an independent company, Twitter may need to address its unusual leadership situation, analysts said.

Dorsey also serves as CEO of digital payments company Square Inc (SQ.N) and has split his time between the two companies since he returned as Twitter's permanent CEO about a year ago.

Investors are likely to pressure the company to appoint a “full-time” chief executive, said SunTrust Robinson Humphrey analyst Robert Peck.

"The most common question we receive from investors is given the struggling turnaround, doesn't the company need a full-time CEO?" Peck said.

Dorsey sent a memo to employees earlier this month calling the company "the people's news network," and rallying them to "deliver a better Twitter faster."

Twitter enjoyed a period of explosive growth in both users and revenues after its founding a decade ago, but growth has stalled over the past several years.

Both Facebook Inc's (FB.O) Instagram and Snapchat.now boast more users than Twitter by most measures, even though they are much newer, and advertisers have begun to migrate their ad dollars accordingly.

The company missed Wall Street's sales expectations in both the first and second quarters of 2016, according to Thomson Reuters StarMine, and has yet to produce a net profit in 11 quarters as a public company. It will report third quarter results Oct. 27, which SunTrust analyst Peck said he expects to be weak with monthly active users flat or down.

To be sure, Twitter has become a focal point in the U.S. presidential election. Many stories have unfolded on its service and comments made by the candidates have made big news themselves. No media company has a mobile product with as much reach as Twitter, BTIG analyst Rich Greenfield said.

Twitter has recently signed deals with a number of media companies and sports organizations to stream major events such as the presidential debates and Thursday Night National Football League games.

A potential acquisition of Twitter had weighed on Salesforce's stock since news broke on Sept. 23 that it was vying for Twitter.

Salesforce, which is focused on cloud-based sales and marketing software, would be the latest bidder to walk away from Twitter, which has had been exploring a potential sale to a handful of buyers, Reuters previously reported. Google  and Walt Disney Co had initially explored interest in an acquisition but walked away in recent weeks, sources told Reuters earlier this week.

Since its founding a decade ago, Twitter has struggled to generate revenue growth and profit, despite having some 313 million average monthly active users and a growing presence as a source of news.

Bob O'Donnell, chief analyst with market research firm TECHnalysis, said Twitter is in a "challenging position." If it doesn't find a buyer, it needs to change the way it does business, he said.
