Both business customer and consumer operations contributed to this revenue growth, on the back of customer growth and a positive trend in business with MVNOs in the Netherlands. The GD Towers unit also recorded a year-on-year increase in revenue, driven by volume-based growth at DFMG. EBITDA AL, adjusted EBITDA AL EBITDA AL increased from EUR 220 million in the prior-year period to EUR 249 million. This growth was mainly attributable to the earnings contributed by Tele2 Netherlands and the aforementioned positive effects on revenue. Efficient cost management also contributed to the growth in EBITDA AL. EBITDA AL of the GD Towers unit is increasing steadily thanks to growing volumes. In addition to the positive effects from the acquisition of Tele2 Netherlands, EBITDA AL of T-Mobile Netherlands was impacted by the transfer of the EBITDA AL contribution of the Dutch cell tower business to GD Towers. Furthermore, earnings from operations increased on the back of revenue growth and efficiency enhancement measures. For the same reasons, adjusted EBITDA AL increased from EUR 225 million to EUR 255 million. The decline in the EBITDA AL margin is attributable to the integration of Tele2 Netherlands. EBIT Due to the consolidation of Tele2 Netherlands at T-Mobile Netherlands and the associated increase in depreciation, amortization and impairment losses, as well as one-time effects resulting from the integration, EBIT decreased by EUR 22 million compared with the first quarter of 2018 to EUR 126 million. GD Towers’ high investments in new cell sites also increased depreciation, amortization and impairment losses. Whereas previously expenses had been recognized in connection with operating leases, the right-of-use assets recognized in this context since the application of accounting standard IFRS 16 as of January 1, 2019 result in particular in higher depreciation charges. Cash capex Cash capex increased by EUR 1 million compared with the prior-year period, primarily due to the additional investments for the integration of Tele2 Netherlands.
