The world’s biggest social media company, headed by CEO Mark Zuckerberg, kept costs in check in the third quarter, with total expenses of $23.2 billion and capital expenditure of $9.2 billion. It projected a slightly improved expense picture for the year as well, narrowing its total expense forecast to $96 billion to $98 billion.

In its press release, however, it warned of “a significant acceleration in infrastructure expense growth next year as we recognize higher growth in depreciation and operating expenses of our expanded infrastructure fleet.”
