As announced at the December 2018 Capital Markets Day, we aim to deliver sustainable profitable growth over the 2018-2021 period, targeting a healthy Operating Free Cash Flow CAGR(a) of 6.5 to 8.0% over the next three years (excluding the recognition of football broadcasting rights and mobile spectrum licenses, and excluding the impact of IFRS 16 on our accrued capital expenditures).
On the back of our Q1 2019 results, we reaffirm our 2019 financial objectives as presented on February 14, 2019 and as summarized in the table below. As a reminder, both our top line and Adjusted EBITDA performance in 2019 will be impacted by (i) the loss of the MEDIALAAN MVNO contract with a more pronounced impact on our financial performance as of Q2 2019, (ii) continued regulatory headwinds, which we expect to abate as of next year, (iii) the full achievement of BASE-related synergies by end-2018 and (iv) higher commercial costs to reignite growth in 2020 and 2021.
For the full year 2019, we continue to expect a revenue decrease of around 2.5% year-on-year on a rebased basis. Against the backdrop of a declining top line and the achievement of substantially all MVNO-related synergies as part of the BASE acquisition in 2018, we anticipate our Adjusted EBITDA(b) to contract between 1 and 2% year-on-year in 2019 on a rebased basis. Excluding the lower contribution from our MVNO business, both our anticipated revenue and Adjusted EBITDA performance in 2019 would have been broadly stable on a rebased basis.
As mentioned before, 2018 represented the peak in our investment cycle given the continued upgrade of both our fixed and mobile infrastructure. Given the substantially lower capital intensity in 2019, we target robust Operating Free Cash Flow(a) growth of 16-18%(c) year-on-year in 2019. For 2019, we anticipate Adjusted Free Cash Flow(d) between €380.0 and €400.0 million. Our 2019 Adjusted Free Cash Flow performance will be impacted by (i) a substantially lower contribution from our vendor financing platform as we aim to stabilize our platform relative to a €93.7 million net positive contribution in 2018, (ii) a negative working capital impact from the reduced capital intensity, (iii) higher cash taxes given our higher pre-tax profitability and (v) higher cash interest expenses relative to 2018 as a result of higher debt balances in connection with last year's extraordinary dividend and as 2018 was impacted by the phasing of our cash interest and derivative payments.
1 Our rebased FY 2018 revenue, Adjusted EBITDA and Operating Free Cash Flow slightly changed as compared to February 14, 2019 due to a further analysis of the acquired Nextel business as of May 31, 2018 from €2,556.4 million, €1,368.4 million and €712.6 million, respectively.
