FCF: $126M -- TwitterIR (@TwitterIR) April 26, 2017 The company's " daily active user" count rose 14% from the prior-year period, it said, while " monthly active usage" rose by 9 million, to 328 million. That was better than Street consensus for a net-add of 4 million, and total of 321 million. Daily active usage increased 14% Y/Y, the 4th consecutive quarter of accelerating growth. #TWTR -- TwitterIR (@TwitterIR) April 26, 2017 Twitter said it was the fourth quarter in a row "of accelerating growth" in daily usage, and called the MAU growth " strong." "We believe our audience growth has been driven by a combination of: organic growth (reflecting some seasonal strength), product improvements (including better relevance in the timeline and notifications), and marketing." Twitter's advertising revenue declined by 11%, it said, to $474 million, while "data licensing" revenue was up 17% at $74 million. The part of that total that is "owned and operated" by Twitter itself declined 11%, to $415 million. Said Twitter, " After a challenging start to the quarter, the growth trajectory for O&O improved and we saw more stable revenue trends beginning in mid-February." Twitter's Ebitda, on an adjusted basis, declined 6% to $170 million, but was "our highest adjusted EBITDA margin to date, despite the year-over-year decline in revenue," the company said, at 31% of revenue. It was also much higher than the $98 million the Street had been modeling. For the current quarter, the company sees Ebitda, on an adjusted basis, of $95 million to $115 million. For the full year, it expects its expenses, on a non-GAAP basis, to be in a range of flat to down 5% with the prior-year period. The company said "continues to expect revenue growth to meaningfully lag audience growth" this year.
