Pinterest Inc. shares fell about 10% in after-hours trading on Thursday after the image-sharing platform reported second-quarter earnings that beat revenue expectations but missed on profit. Revenue for the quarter ended 30 June rose 17% from a year earlier to $998.2 million, topping the $974.8 million consensus. Adjusted earnings per share came in at $0.33, short of the $0.35 analysts expected. Net income increased to $38.8 million from $8.9 million a year ago, while adjusted EBITDA climbed 39% to $250.8 million, expanding the margin to 25%. Free cash flow nearly doubled to $197 million. Monthly active users grew 11% to a record 578 million, with the company saying Generation Z now accounts for more than half of its audience. Geographic results were led by Europe, where revenue jumped 34%. Looking ahead, Pinterest forecast third-quarter revenue of $1.03 billion to $1.05 billion and adjusted EBITDA of $282 million to $302 million, both above Wall Street projections. Chief Executive Officer Bill Ready said the firm is entering the next phase of its business transformation on “a strong foundation of user and revenue growth,” noting a modest foreign-exchange tailwind in the outlook.
