EBITDA, decreased severance, acquisition and other costs, and lower other expense due to lower year-over-yearnon-cash media asset impairment charges. This was partly offset by increased depreciation and amortization expense and higher finance costs. For full-year 2019, net earnings increased 9.4% to $3,253 million while net earnings attributable to common shareholders were $3,040 million, or $3.37 per share, up 9.2% and 8.7% respectively. The adoption of IFRS 16 did not have a significant impact on net earnings.
Adjusted net earnings in Q4 were $794 million, or $0.88 per common share, compared to $794 million, or $0.89 per common share, in Q4 2018. The decrease in adjusted net earnings per share (adjusted EPS) was attributable to the factors discussed above as well as a higher average number of common shares outstanding compared to the previous year. For full-year 2019, adjusted net earnings were $3,153 million compared to $3,151 million in 2018, and adjusted EPS was down 0.3% to $3.50.
Adjusted EBITDA in Q4 grew 4.8% to $2,508 million, driven by increases of 7.4% in wireless, 1.5% in wireline and 16.5% in media. BCE’s consolidated adjusted EBITDA margin(2) increased 1.2 percentage points to 39.7% due to the high flow-through of service revenue growth, increasing broadband Internet scale and ongoing cost discipline as reflected in a 0.3% reduction in total operating costs. Consistent with our guidance target range of 5% to 7% growth for the year, adjusted EBITDA increased 6.0% to $10,106 million in 2019, while BCE’s consolidated EBITDA margin expanded to 42.2% from 40.6% in 2018. Adjusted EBITDA was impacted positively by IFRS 16 as most operating lease expenses are now recorded as depreciation and interest expense rather than operating costs within adjusted EBITDA.
BCE invested $1,153 million in new capital in Q4, compared to $974 million the year before. This timing related year-over-year increase brought total capital expenditures for 2019 to $3,988 million, up slightly from $3,971 million in 2018, and represented a capital intensity(5) ratio (capital expenditures as a percentage of total revenue) of 16.6%, compared to 16.9% the year before. Capital spending in 2019 focused on further expansion of Bell’s combined FTTP and Wireless Home Internet footprints to approximately 760,000 additional locations; the connection of fibre Internet and TV services to more homes and businesses; ongoing wireless network investment, including the deployment of small cells to increase LTE Advanced(LTE-A) coverage, speed and quality, and to expand fibre backhaul in preparation for the launch of 5G service; as well as spending on digital media platforms.
BCE cash flows from operating activities in Q4 were $2,091 million, up 16.9% over last year. The increase was due mainly to adjusted EBITDA growth, lower interest paid and no voluntary contribution made to post-employment benefit plans at the end of 2019 compared to $240 million in 2018, partly offset by higher income taxes paid. Free cash flow decreased 12.5% in Q4 to $894 million, from $1,022 million the year before, due to increased capital expenditures, partly offset by higher cash flows from operating activities excluding acquisition and other costs paid and voluntary pension contributions. For full-year 2019, BCE cash flows from operating activities totalled $7,958 million, up 7.8% compared to 2018, while free cash flow grew in line with our guidance growth target of 7% to 12%, increasing 7.0% to $3,818 million.
In Q4, BCE reported 123,582 net new wireless customers (121,599 postpaid and 1,983 prepaid); 35,639 net new retail Internet customers; 22,039 net new IPTV customers; a net loss of 21,618 retail satellite TV customers; and a net loss of 58,110 retail residential NAS lines.(5)
BCE wireless and retail Internet, TV and residential NAS connections totalled 18,983,510 at the end of 2019, up 1.3% over 2018. The total includes 9,957,962 wireless customers(4), up 3.6%
