Hon Hai Precision Industry Co, better known by its parent company name Foxconn, posted record quarterly profits in the final quarter of last year, citing increased production and improved efficiency of iPhones and iPads, as reported by Bloomberg.

Net income rose 5.6 percent to $1.2 billion, ahead of analyst expectations, but may face more challenging times ahead …

Bloomberg speculated that Foxconn’s increased profitability while Apple’s margins fell may suggest that the supplier has been able to negotiate higher prices for components and assembly.
