It emerged in June that Guardian News & Media made operating losses of £38.3 million ($80.3 million), widening from £37.8 million a year earlier.
The group announced a "digital first" strategy and drew up a plan to save £25 million by 2016.
Andrew Miller, GMG chief executive, said the group could run out of cash in three years if there was not an overhaul. It emerged this month that the group was considering closing its £80 million printing plant.
The group bought ContentNext in 2008 for an undisclosed fee.
It said the acquisition of the group set up by journalist Rafat Ali in 2002 was to target "significant expansion" in the United States.
