Ostensibly, they've sold it back years ago.
But that just means they don't need to officially own it anymore: Alex Mandl, Gemalto's current chairman, is among others a former board member of intQtel, which presents its mission on its web page as:
We identify, adapt, and deliver innovative technology solutions to support the missions of the Central Intelligence Agency and broader U.S. Intelligence Community.
So the news that nobody wants spread is: nobody cares about how much the NSA stole from Gemalto: whatever Gemalto has and NSA wants, the NSA is most likely to get by simply asking NSA affiliates installed at every interesting node in Gemalto's hierarchy.
Incidentally, it's rather easy to find sources about this in French (Gemplus used to be a French company, before the fusion with Axalto which was forced by intQtel and TPG), but surprisingly hard to find in English.
