In an interim management statement released today, Pearson reported that digital subscriptions stand at "almost 387,000", a 24 per cent increase on 2012. In its nine-month statement last year the figure stood at 313,000.
At a conference earlier this month, Mary Beth Christie, online product management director at Financial Times, said 24 per cent of of digital subscriptions are made from mobile devices.
She also told the conference that the number of digital subscribers of the FT is 100,000 higher than print subscribers.
Today's statement reports that across both platforms, the news outlet has recorded its "highest circulation in its 125-year history", with a reported figure of 629,000.
This represents a 5 per cent rise on 2012, the statement adds. However "advertising remains weak and short-term".
2013 has been a busy year on the digital side for the Financial Times. In April it released its redesigned web app, followed by the arrival of fastFT in May, which offers readers a real-time feed of "market-moving news".
In September the FT announced its new vice president of communities, and earlier this month editor Lionel Barber shared more details with staff about how the news organisation will continue in its efforts to become a digital-first operation.
This also included details about a "significant reshaping of the newspaper".
"Our plan is to launch a single edition, global print product in the first half of 2014," Barber said at the time. "The new FT will be redesigned and updated to reflect modern tastes and reading habits".
