July 10 : Global investment banks and brokerages leading SK Hynix's mega share sale earned nearly $260 million in fees, a boost for the industry which took in a relatively modest $500 million from SpaceX's record share sale last month.The fees equate to about 0.97 per cent of the total amount raised, SK Hynix's filings showed, meaning bankers earned more as a percentage of deal size than those who worked on SpaceX's initial public offering.SpaceX bankers earned 0.67 per cent or $500 million of the $75 billion in an IPO which eclipsed the previous record set by Saudi Aramco in 2019, as well as SK Hynix's U.S. listing this week.Citigroup earned over $70 million from the SK Hynix sale, which was 20 per cent more than other banks on the deal, said a person with direct knowledge of the matter,
