Facebook's Quarterly Profit Slips as Costs Soar
Facebook Chief Operating Officer Sheryl Sandberg said in an interview the huge increase in expenses was for "growth we need now and in the future."
"We're investing in the next set of services and what will be future investments like Messenger, WhatsApp and Oculus," she added.
Macquarie Research analyst Ben Schachter said Facebook's costs and spending met expectations. "We think the company has a lot of opportunities ahead of it so we want to see them investing quite heavily in those investments," he said.
