Detailed performance indicators such as profit are not supplied in Experian owner GUS's results. Neither did GUS comment on when it will act on its pledge to sell off Experian.
However, GUS revealed that Experian's non-US turnover grew by 22%, of which 15% came from acquisitions. QAS, bought for £106m in October last year, accounted for most of that amount and is winning "significant contracts" with the public sector.
Email marketing was strong both outside and inside the US. Inside the US it saw strong organic sales growth, along with database management and automotive marketing clients.
Overall US sales, including its credit division, increased by 33%, and 20% excluding the contribution from acquisitions.
John Peace, GUS chief executive, said Experian's growth was "exceptionally strong", pointing in particular to the jump in sales in the North American division.
The proportion of turnover accounted for by the US is around 55%.
