Between 1,000 and 1,500 jobs are expected to be lost at Teva Pharmaceutical Industries as part of the company’s cost-cutting measures.

Reports from Israel claim the majority of the layoffs will be made in the US and Europe and mainly focused in Teva’s recently acquired Cephalon’s generic business.

The reports say that Teva is hoping to raise $500 million in synergies from its takeover with job losses expected to raise the majority of its target.

Teva has already said it is planning to cut sales, marketing and administrative expenses by $300 million, R&D by between $120 million and $150 million, and production costs by $50 million to $80 million. R&D savings would be achieved by cutting duplicate operations, the company said.

Teva has a history of job losses following takeovers of generic companies. In 2008 it bought US generic specialist Barr and reduced its workforce by 10%, reports say.

A reduction of 1,000 jobs at Cephalon would represent a loss of 27% roles before the takeover. But one company where job losses will be made, the reports say, is at Mepha, the Swiss generics manufacturer Cephalon bought last year. The company had 620 jobs prior to the acquisition.

Merck saw revenues increase by 3.8% to €2.5 billion and net profit rise 7.5% to €227 million in the third quarter after solid performances by its pharmaceuticals and Millipore divisions.

Revenues at Merck Serono increased 5.4% to €1.4bn after increased global sales of Rebif and Erbitux (pictured) whilst its Millipore division saw revenue reach €588 million compared to €559 million the same period a year ago.

Karl-Ludwig Kley, Chairman of the Executive Board of Merck KGaA, says the results leave the Group “well positioned as we head into the end of the year”.

Its Executive Board now forecasts annual Group revenues between €10-10.2 billion and the debt resulting from the 2010 acquisition of Millipore to decrease at an “excellent pace”.

Administration expenses were down 2.7% to €124 million with other operating expenses and income also declining slightly by 1.3%. R&D costs increased to €371 million in Q3 due to a combination of late-stage clinical trials and the strong Swiss franc.

Earnings before interest and tax were also down 8.4% with underlying core operating result – which excludes Merck Serono and Millipore – decreasing by 21.5% of revenues as a result of the weakening of the Performance Materials division, the Group claimed.

Generic organic revenue growth in Merck Serono increased nearly 9% after its multiple sclerosis treatment Rebif recorded global sales of €426 million and the cancer treatment Erbitux earned € 218 million, primarily as a result of growth in emerging markets.

“The Merck Group produced solid third-quarter revenue growth in a difficult environment, driven mainly by good performances from the Merck Serono and Merck Millipore divisions,” said Karl-Ludwig Kley. “We are making progress in driving our change agenda forward and we will provide important updates on this endeavour in the first half of 2012.”
