12 Takeover Rumors Targeted by Short Sellers

8. Gerresheimer AG (OTC:GRRMY)

Short Percentage of Float: 11.23%

Gerresheimer AG (OTC:GRRMY) is one of the takeover rumors targeted by short sellers.

On April 17, 2026, Reuters reported that Gerresheimer had rejected a takeover bid from U.S. packaging company Silgan, citing three sources familiar with the matter. Reuters said the two companies were no longer in talks and added that Silgan’s earlier non-binding approach had valued Gerresheimer at €41 per share, more than double the company’s then-current share price.

Reuters also reported that Gerresheimer wanted to focus on resolving its accounting problems and selling its U.S. subsidiary, Centor, before pursuing any deal. That detail mattered because it suggested the company was stepping back from a bid despite the large premium implied by Silgan’s approach.

The market reaction then shifted as investors absorbed the report. Investing.com, citing Reuters, said Gerresheimer shares were up about 1.7% in European trading by 09:28 GMT after initially falling more than 5%, showing that the stock regained ground even after news that the bid had been rejected.

Gerresheimer AG (OTC:GRRMY) is a German manufacturer of pharmaceutical, biotech, and medical packaging and delivery systems.
