Bombardier has released its 2019 business unit guidance and confirmed that it remains on track to achieve its 2020 financial objectives. The 2019 guidance reflects the anticipated closing of the sale of both Business Aircraft's flight and technical training activities and the Q Series aircraft program as of September 30, 2019.
For 2019, Bombardier is targeting revenues of US$18 billion or more, representing a year-over-year increase of approximately 10% over 2018 guidance. This growth is expected to be driven by: the entry-into-service of the Global 7500 aircraft, which is sold out through 2021; execution on Bombardier's strong US$34-billion rail backlog, which covers more than 80% of Transportation's targeted 2019 and 2020 revenues; and an increased focus on aftermarket services across the portfolio. Aftermarket revenues are estimated to grow from approximately US$3.5 billion in 2018 to approximately US$4.0 billion in 2020 as the Company continues to optimize its aftermarket and services operations, leveraging its large installed base which includes over 100,000 rail cars, more than 4,700 business jets and approximately 1,250 regional jets.
Profitability is anticipated to grow faster than the top line, and is expected to be driven by solid conversion on revenue growth and the strategic reshaping of Commercial Aircraft. EBITDA before special items is targeted to grow by approximately 30% over 2018 guidance to a range of US$1.65 billion to US$1.80 billion, while EBIT before special items is targeted to increase by approximately 20% over 2018 guidance to a range of US$1.15 billion to US$1.25 billion.
From a free cash flow perspective, 2019 is expected to mark the transition from a heavy investment cycle to a strong growth and cash generation cycle. Sustainable capital expenditures are projected to decrease to approximately US$800 million or less on an annualized basis, which represents a decrease of approximately 50% from the previous five-year average.
On a normalized basis, before one-time items, Bombardier estimates free cash flow in a range of US$250 million to US$500 million for 2019. One-time items that are expected to impact free cash flow in 2019 include; a US$250-million charge for the previously announced restructuring; and a working capital contingency of US$250 million largely associated with the intense ramp-up of the Global 7500 program. Free cash flow including these one-time items is targeted to be breakeven plus or minus US$250 million, resulting in an estimated cash on hand exceeding US$3.0 billion by year end.
Along with announcing its 2019 business unit guidance, Bombardier reaffirmed its 2020 objectives of revenues in excess of US$20 billion, EBITDA before special items over US$2.25 billion, EBIT before special items over US$1.6 billion and free cash flow between US$750 million and US$1 billion. In addition to generating strong cash flow from operations, Bombardier anticipates ending 2020 with strong liquidity, including more than US$3.5 billion of cash on hand and a significantly improved leverage ratio.
