Omeros Corporation (OMER) Accuses Short Seller of Manipulation

Omeros' Response to Short Seller Accusations Sends Shares Up

Omeros Corporation (NASDAQ:OMER) shares tumbled nearly 9% yesterday, following a bearish report issued by Art Doyle research, a group that identifies as having a short position in Omeros’ stock.

“As we will show you in this report, Omeros tried to do subcutaneous delivery in their Phase 1 for OMS721. But at the end they magically added IV. And haven’t looked back since. IV all the way baby. So they will tell you that they have a competitive product but like most everything that seems to come out of their mouth, it isn’t true. Omeros doesn’t have subcutaneous in Phase 2 and they never will. What are they hiding about their Phase I data,” Art Doyle said.

“We went to Mexico. We went to Madrid. We actually have the Omeros phase 2 data that they say is so great for OMS721. Newsflash: It isn’t great! We will show it to you since Omeros won’t. The CEO can try to sue us, but we aren’t your old CFO who called you out on a whistleblower case. You know, the one Omeros paid almost $4 million to settle,” the research group continued.

In response, Omero stated that the report is replete with falsehoods, misleading statements and incorrect analyses and conclusions. “Art Doyle” states that it stands to profit in the event that Omeros’ share price declines. The report is actionable and the company is pursuing legal remedies. Omeros intends to hold all responsible parties accountable.

Shares of Omeros are up nearly 6% to $21.64 in pre-market trading Thursday. OMER has a 1-year high of $27.09 and a 1-year low of $7.20. The stock’s 50-day moving average is $18.33 and its 200-day moving average is $13.73.
