Gotham City Research has once again questioned the Spanish pharma group Grifols' ties with a company called Scranton Enterprises.
Gotham via its website has posed a series of incendiary questions, following on from its negative analysis last month.
Earlier in the session Grifols shares were down 7% but recovered some of their poise to close out a turbulent day down just 0.5%.
The drugs group's company secretary has been quoted as offering this rebuttal: “Grifols once again categorically refutes Gotham’s malicious, false and misleading insinuations that has the sole objective of destabilising Grifols and causing doubts amongst institutional investors.”
Proactive has reached out to Grifols for a comment.
