Mallinckrodt Announces Base Price Dispute with DHS; Shares drop nearly 25%

According to an article in the Wall Street Journal on May 21, 2019, Mallinckrodt filed a lawsuit against the Department of Health and Human Services after the Centers for Medicare and Medicaid Services had determined Mallinckrodt would have to pay additional money to states due to a change in the base date average manufacturer price for its injected drug, Acthar.

Mallincrkodt estimated it may have to provide as much as $600 million in retroactive rebates if the lawsuit was not successful, according to the article.

A Bloomberg article also noted that Berenberg analyst Patrick Trucchio slashed his price target in half to $5, stating:

“’The timing of this disclosure is potentially problematic’as the company doesn’t seem to have warned investors of this risk despite its disagreement with the government dating back to 2016, Trucchio said in a note to clients.”

On this news, share price fell nearly 25% to close at $9.87 on May 21, 2019.

Stock Plummets on News that Mallinckrodt Unit Is Accused of Bribery to Drive Drug Sales

Prior to that, on May 1, 2019, the Wall Street Journal published an article entitled, “Government to File Complaint After Mallinckrodt Unit Is Accused of Bribery to Drive Drug Sales.” The article reported that Questcor, which Mallinckrodt acquired in 2014, “defrauded government health-care plans by illegally marketing H.P. Acthar Gel.”

The article further states that whistleblowers alleged that the company paid doctors kickbacks through bribes, consulting agreements and speaking fees if they prescribed Acthar.

On this news, Mallinckrodt’s share price fell by more than 16%.
