Goldman Sachs and the other advisers of Infineon Technologies had to fight tooth and nail for the €33m ($28m) they made on the embattled German semiconductor manufacturer's €1.5bn share sale, but on Friday morning they could finally lay claim to it.

After a turbulent run from Infineon stock, the sale was eventually 3.75 times oversubscribed at €24.88, and priced just above that at €25. That represented a 3.8% discount to Thursday's closing price of €26.
