Teva Pharmaceutical Industries Ltd. (TEVA) swung to a fourth-quarter profit as sales jumped, buoyed by a 25% rise in sales of multiple sclerosis drug Copaxone and its 2008 acquisition of Barr Pharmaceuticals.

The Israeli generic drug maker dominates the consolidating generic-drug industry as the branded pharmaceutical sector is under pressure from looming patent expirations in coming years. Teva recently projected revenue will more than double to $31 billion in 2015, and backed its 2010 outlook Tuesday, warning that foreign-exchange volatility could have an impact on revenue.

J.P. Morgan analyst Chris Schott noted that Teva's fourth-quarter results were in line with expectations, but he is encouraged by Teva's sales trends heading into an "exceptionally strong" year.

American depositary shares of Teva recently traded down 32 cents to $58.54.

During a conference call Tuesday, Chief Executive Shlomo Yanai said the fourth-quarter results demonstrate the company's business balance amid a troubled world economy, volatile market conditions, and foreign exchange effects.

Teva projects 2010 earnings of $4.40 to $4.60 a share, excluding items, on revenue of about $16 billion, but warned that foreign-exchange volatility may continue.

In the fourth quarter ended Dec. 31, exchange rate differences contributed $98 million to sales, while hurting sales by $572 million for the total year.

Teva's wide geographical presence provides a "natural hedge" to that currency exposure and minimizes the impact on the company's earnings.

Wall Street currently expects 2010 earnings of $4.54 a share, excluding items, on revenue of $16 billion.

during the call, Chief Financial Officer Eyal Desheh said there would be "significant variance" between the first quarter and the rest of the year citing the timing of new generic launches, regular seasonality and an increased benefit from competitor supply disruptions as the year progresses.

For the fourth quarter, Teva's earnings were $379 million, or 42 cents a share, compared to a loss of $694 million, or 88 cents a share, a year ago. The year-ago results were weighed down by items related to the $7.46 billion Barr deal.

Excluding items, earnings were 94 cents a share in the latest quarter, just shy of a Wall Street projection of 95 cents, according to Thomson Reuters.

Sales rose 33% to $3.8 billion, about in line with analyst expectations, from $2.85 billion, with the integration of Barr boosting sales in all regions, particularly in the U.S., Russia, Poland, Germany and Croatia.

Global sales of Copaxone rose 25% to $747 million; in the U.S., sales increased 33% to $509 million.

The company said it plans to submit for U.S. regulatory approval of a lower-volume formulation of Copaxone, which may reduce injection pain and site reaction, by the end of March.

Fourth-quarter pharmaceutical sales in North America increased 35% to $2.32 billion, accounting for 61% of all pharmaceutical sales. Teva said it benefited from generic launches including Takeda Pharmaceutical Co. Ltd.'s (4502.TO) Prevacid, Sanofi-Aventis SA's (SNY, SAN.FR) Allegra-D 12 Hour and the re-launch of AstraZeneca Plc's (AZN, AZN.LN) Pulmicort Respules.

In Europe, pharmaceutical sales rose 30% to $925 million, while international pharmaceutical sales rose 35% to $553 million.

As of Feb. 5, Teva had 216 product applications awaiting Food and Drug Administration approval, covering annual U.S. branded sales of over $113 billion.

Of the 140 patent challenges included in that figure, Teva believes it is the first to file--providing 180-day market exclusivity--on 89 applications with annual U.S. branded sales exceeding $55 billion.

Teva also boosted its quarterly dividend by 16.7% to 0.7 shekel, or about 18.7 U.S. cents.

The company has been making acquisitions in recent years and is still looking for targets as it seeks to become less dependant on Copaxone and the concentration of sales in North America. It has said it plans about $5 billion of smaller acquisitions, mostly outside the U.S., through 2015.

Teva is still in the running to acquire Ratiopharm International, the generic drugs company being sold by Germany's Merckle family, after the second round of bidding, a person familiar with the matter told Dow Jones Newswires earlier this month. It is competing with U.S. pharmaceuticals company Pfizer Inc. (PFE), Swedish private equity firm EQT Corp. (EQT) and Iceland's Actavis Group (ACT-IC), the person said.

Although he declined to comment on Teva's interest in Ratiopharm, Yanai said Tuesday that Europe is key to its future growth for the next five years.
