Pandora Media Inc forecast current quarter adjusted profit below analysts' estimates as it plans to plow money back into the business. The company's shares fell about 6 percent in extended trading.

Analysts on average were expecting an 8 cents per share in profit on revenue of $234.6 million, according to Thomson Reuters I/B/E/S.
Pandora Chief Financial Officer Mike Herring said in an interview that adjusted profit forecast was because the company plans to "reinvest aggressively."
Pandora faces stiff competition from Spotify, Apple Inc's Beats online streaming service, Google Inc and Amazon.com Inc in the fast-growing music streaming business as downloads decline.
"There is no shortage of well-funded aggressive smart competitors in the space," Herring said. "That said, there has been for years and we have continued to grow market share."
