A strong performance from HarperCollins and the acquisition of Harlequin has boosted parent company News Corp's quarterly results.
Revenue for publisher's worldwide operation for the second quarter of the financial year, covering the three months to December 31st 2014, increased 20% from $391m (£256m) to $469m (£307m), according to results released by New Corp.
EBITDA was also up, growing from $68m (£44.5m) to $77m (£50.4m). The results do not break out the performance of HarperCollins UK.
News Corp stated that HarperCollins' boost was "driven by the inclusion of the results of Harlequin Enterprises Limited and strong performances in children's and general books resulting from higher backlist sales during the holiday season, which largely offset the lower revenues from the Divergent series."
E-book revenues also grew by 14% compared with the same period the previous year, again driven by Harlequin, with digital sales now representing 17% of consumer revenues at HarperCollins. However, overall adjusted revenues were flat, with adjusted segment EBITDA decreasing 4% compared to the previous year.
News Corp chief executive Robert Thomson said: "Our digital personality has evolved quickly", highlighting "healthy e-book sales at HarperCollins". He added: "The vision we outlined for the company is becoming a reality, and while we have much work ahead, the foundations we have laid over the past 18 months put us in a strong position for enduring success and increases shareholder value."
