Monthly active users continued their slow decline, dropping to 71.4 million from 76 million in Q2 2017, according to earnings released late Tuesday afternoon. But the company was able to do more with less. Revenue grew 12 percent to $384.8 million. Ad RPM, or revenue per thousand impressions, grew 24 percent to $66.15 from $53.34 a year earlier. And subscription revenue jumped 25 percent to $68.9 million. Similar Q1 metrics sent Pandora’s share price soaring in May as well; quarterly revenue grew 12 percent, while ad RPM grew 9 percent.
