(BMY) - Get Report

reported a sharply lower profit in the third quarter as generic competition continued to eat away at drug sales and the company ratcheted up spending on research and development of new drugs.

Net income slid 16.3% to $ 758 million, or 38 cents a share, vs. $906 million, or 47 cents a share, in the year-ago period. Excluding items, the company earned 44 cents a share. Revenue increased 1% to $5.42 billion.

The Thomson First Call consensus forecast was $771.4 million, or 39 cents a share, on revenue of $5.3 billion.

Generic-drug competition continues to erode revenue, while up-and-coming products aren't coming up fast enough or strong enough.

'We are making good progress executing against our strategy and transforming our portfolio to build or strengthen our leadership position in 10 disease areas, " the company said in a statement. "As part of this strategy, we continue to increase investment in research and development, and expect that investment to grow in the 12% range for the year. Nevertheless, as we have discussed previously, our earnings will continue to be pressured through our portfolio transition to the end of 2006 as a result of exclusivity losses of higher margin products, as well as higher investments in R&D and key product support."

Worldwide pharmaceutical sales were flat at $3.8 billion, while U.S. sales decreased 2% to $2.1 billion. In particular, global sales of Paraplatin slid 28% to $177 million.
