** SOBI said it would make a tender offer for $9.10 per CTI
share, a premium of 89% over Tuesday's closing price of $4.82

SOBI's haematology franchise, the purchase premium is
significant, though within peer multiples in the rare disease
space

transaction may initially be perceived negatively
** The planned deal is fully funded through debt financing,
up to half of which is expected to be refinanced through a
rights issue

STOXX 600 .STOXX index
