UPDATE 2-Drug distributor AmerisourceBergen cuts revenue growth forecast

(Adds forecast, details and analysts' comments)

Aug 3 (Reuters) - AmerisourceBergen Corp cut its revenue growth forecast for fiscal 2017, adding to the woes of the drug distribution industry as it continues to struggle with drug pricing.

The pharmaceutical supply chain, including pharmacy benefit managers and drug distributors, has been under pressure due to intense scrutiny over soaring drug prices.

McKesson Corp last week posted a lower-than-expected quarterly profit, hurt by a slowdown in branded drug price inflation, while Cardinal Health on Wednesday forecast fiscal year 2018 profit well below analysts' estimates.

Leerink analysts said the results this quarter were slightly disappointing, though not entirely unexpected, given Cardinal Health and McKesson's recent reports and called the slight reduction in forecast "disappointing".

AmerisourceBergen shares were down 3 percent in light premarket trading.

The drug distributor said it now expects revenue growth of about 5 percent for the fiscal year. It had previously forecast revenue growth of 5.5 percent to 6.5 percent.

The company, however, maintained its forecast for branded drug price increases and fall in generic drug prices.

AmerisourceBergen said operating income in its pharmaceutical distribution unit fell 8.7 percent, hurt by "lower price appreciation".

Baird analysts said the results were not overly surprising, but noted that the tone and outlook were more comforting than AmerisourceBergen's rivals.

Revenue rose 5 percent to $38.71 billion in the third quarter ended June 30.

Excluding items, the company earned $1.43 per share, beating analysts' average estimate of $1.37, according to Thomson Reuters I/B/E/S.

Analysts attributed the profit beat mainly to a lower tax rate.

However, net income fell to $50.4 million, or 23 cents per share, in the quarter, from $349.2 million, or $1.55 per share, a year earlier.

Operating expenses rose to $909.5 million from $579.2 million.
