Pandora is down almost 8% in after-hours trading after mildly disappointing Q2 results.
Pandora lost 12 cents per share, excluding certain items, slightly better than analyst estimates of a 14 cents-per-share loss. But the music streaming company only generated $343 million in revenue, missing analyst estimates of $351.3 million.
Pandora also lowered its revenue guidance for Q3, expecting revenue between $360 million and $370 million, below the $378 million expected by analysts.
