The group reported adjusted earnings before interest, taxes, depreciation and amortisation (EBITDA), at 670.6 million euros ($684.1 million) for the six months ended June 30.
Net profit jumped 275% to 793.4 million euros, driven by the sale of Telenet's telecommunications tower business.
Telenet confirmed its full-year outlook and expects a stronger second half both in terms of revenue and adjusted EBITDA.
