According to the Zhito Finance APP, after several media reported that the Canadian asset management company brookfield asset management (BAM.US) has abandoned its plan to privatize grifols (GRFS.US), the stock price of this plasma therapy company fell over 18% in pre-market trading on Wednesday.

According to media citing a spokesperson for the grifols family, disagreements over the company valuation led to this decision. It is reported that the family agreed in September to cooperate with brookfield to privatize grifols.

The spokesperson stated: "brookfield has withdrawn its acquisition proposal because there are differences in pricing between the two parties. The company’s value is much higher (than brookfield's quote). We will stand our ground."

Last week, the grifols board of directors rejected the initial quote from brookfield, which valued the Spanish company at 6.45 billion euros (6.8 billion dollars). Spokespersons for grifols and brookfield refused to comment on the latest developments.

Meanwhile, reports surfaced that the billionaire grifols family indicated they would not support a new proposal from a third party to privatize the company. A spokesperson stated: "The family will not support another privatization deal."

"We are very pleased to receive letters from existing shareholders who tell us that the company's value is higher, and we will continue to work to further enhance the company's value."
