Former Teva Pharmaceuticals President and CEO Jeremy Levin denied the company's statement on Wednesday that he had resigned only hours after it was released. Levin told Israeli Channel 10 TV: "I did not resign. I did not choose to leave the company." He declined to comment further.
Teva's chairman Phillip Frost also told Channel 10: "It just got to the point where the slight differences couldn't be resolved. We thought it was better to part ways."
Levin's ousting follows a public uproar over a contentious restructuring plan set to cut thousands of jobs worldwide.
In an earlier statement announcing the resignation, Frost said the board and management were committed to "the planned acceleration of the company's cost reduction program."
Israeli media reported that Levin's downfall culminated months of tension between him and Frost. Those tensions intensified after the company said this month it would reduce its global workforce by about 10 percent -- or 5,000 employees -- as part of a restructuring plan.
The company has struggled in recent quarters with declining sales for both generic and brand-name drugs. The restructuring aims to slim the drug maker's business and make it more efficient.
Channel 2 news reported this week that Levin and Frost fought over how to implement the restructuring. The planned layoffs set off an uproar and sense of betrayal in Israel, which has boosted Teva with years of grants, subsidies and tax breaks. Its success on the global stage has earned it the nickname "Israel's company." Some 800 Israeli employees are set to be laid off.
Under heavy public pressure, Levin agreed to meet with government officials and the Histadrut labor union, vowing to re-evaluate the company's plan. Levin reportedly was intent on carrying out the layoffs gradually, whereas Frost and the board wanted them done immediately.
A letter obtained by Channel 2 said to be from the company's management and sent to the board spelled out the squabble.
"We acknowledge the commitments of members of the board to stockholders. Despite that, we urge the board to reconsider its interference in daily business, which in our opinion has become common in recent months, and prevents the management from managing Teva in an efficient way," the letter said.
In midday trading Wednesday on the Nasdaq stock market, the company's shares were down 7.2% to $38.08 apiece.
Levin is a former senior executive at U.S. drug maker Bristol-Myers Squibb, becoming CEO in 2012. Teva's board named Chief Financial Officer Eyal Desheh as an interim replacement and formed a committee to start headhunting for a permanent successor.
Finance Minister Yair Lapid met Wednesday with Desheh, who promised to uphold prior agreements made between Levin and Lapid regarding Israeli layoffs.
Analysts said Levin's departure reflects a leadership crisis at the company.
"Teva, like most organizations, suffers from a surplus of management and a shortage of leadership, and that is a root problem endangering the future of the pharmaceutical giant," commentator Boaz Tamir wrote on the website of The Marker, an Israeli financial newspaper.
