Pascal Desroches
Senior Executive Vice President, Chief Financial Officer at AT&T
Thank you, John, and good morning, everyone. As John shared, we've maintained our momentum across both 5G and fiber. Let's start by reviewing our fourth quarter financial summary on Slide 7. Revenues were up 2.2% for the quarter and 1.4% for the full year, largely driven by wireless service revenue, broadband revenues and Mexico. This was partly offset by a decline in business wireline. Adjusted EBITDA was up 3.2% for the quarter and 4.7% for the full year as growth in mobility, consumer wireline and Mexico were partly offset by a decline in business wireline.
In the fourth quarter, adjusted EPS was $0.54, down 11.5% for the quarter due to a $0.10 impact from higher non-cash pension costs, lower capitalized interest, lower equity income from DIRECTV and a higher effective tax rate. For the full year, adjusted EPS from continuing operations was $2.41 in line with our previously stated expectations of the low 2.40s range. Free cash flow for the quarter was $6.4 billion, including about $900 million in DIRECTV distributions. For the full year, we came in above our already recently raised guidance with $16.8 billion in free cash flow. This is an improvement of $2.6 billion year-over-year or up 19%. We achieved this free cash flow growth even with about $1 billion of higher cash taxes and about $750 million of lower cash distributions from DIRECTV. Additionally, and as previously mentioned, we reduced vendor financing obligations by $3.3 billion last year.
Cash from operating activities came in at $11.4 billion for the quarter, up $1 billion year-over-year. For the quarter, capital expenditures were $4.6 billion with capital investments of $5.6 billion. Full year capital investment was $23.6 billion as we continued to invest in 5G and fiber at historic levels. We also continue to strengthen our balance sheet. Last year, we lowered net debt by about $3.3 billion, which was also burdened by $1.7 billion increase year-over-year for changes in FX rates related to foreign debt. We additionally completed an $8 billion pension liability transfer through the purchase of insurance annuities last spring, and we've done all this despite overcoming meaningful declines in the legacy wireline part of our business.
Now let's look at our mobility segment operating results on Slide 8. Our mobility business continues to deliver strong results growing both revenues and EBITDA for the sixth consecutive year. We are pleased with our 526,000 postpaid phone net adds for the quarter, particularly given some of the rich promotion by our peers. This success demonstrates that the general health of the wireless industry and the consistency of our go-to-market strategy which continues to resonate with high value customers. Revenues were up more than 4% for the quarter and 2.7% for the year.
Service revenues also continue to improve, thanks to steady and profitable subscriber growth. In the quarter, service revenues rose about 4% while they were up 4.4% for the full year. Mobility EBITDA for the quarter was up about $450 million or 5.6%, driven by growth in service revenues. For the full year, mobility EBITDA grew 7.4% and we continue to see margin expansion year-over-year. Mobility postpaid phone ARPU was $56.23, up 1.4% year-over-year. ARPU growth continues to be largely driven by our targeted pricing actions and from customers trading up to higher priced unlimited plans.
Postpaid phone churn of 0.84% for the quarter remained historically low. Our continued low churn levels clearly demonstrate customers prefer the value proposition they are getting from AT&T. In prepaid, our phone churn was less than 3% with Cricket phone churn substantially lower. We remain encouraged by the overall health of the wireless industry and are confident that our mobility business will deliver again as we expect to continue to growing customers, service revenues and EBITDA to healthy clip in 2024.
Now let's move to consumer and business wireline results, which are on Slide 9. Let's start with consumer wireline. As John mentioned, the financial and operational performance of our fiber business is exceeding our initial expectation. Wherever we have fiber, we continue to win. In the fourth quarter, we added 273,000 fiber customers even in a seasonally slow fourth quarter and lower year-over-year household moves. This accentuates the resiliency of fiber and the superior experience it provides customers. Broadband revenues grew more than 8% year-over-year due to fiber revenue growth.
Fiber ARPU was $68.50, up $0.29 sequentially with intake ARPU now at more than $70. Consumer wireline EBITDA grew more than 10% for the quarter and more than 8% for the full year due to growth in fiber revenues and the more efficient cost profile of fiber. And while fiber remains our focus and lead product, we've also been encouraged by the initial introduction of AT&T Internet Air, our targeted fixed wireless access service. We had 93,000 AT&T Internet Air subscribers at the end of the year and now offer this service in parts of 35 locations.
Turning to business wireline. EBITDA was down about 19% in the quarter. This was impacted by about $100 million of items, primarily discrete intellectual property transaction revenues we had in the fourth quarter of 2022 that did not repeat in the fourth quarter of 2023. As I will discuss in a moment, we expect trends in business wireline EBITDA to improve on a full year basis in 2024. In the fourth quarter, our business solutions wireless service revenues grew nearly 6%. This is an area where we continue to grow faster than our nearest peer. FirstNet also continues to be a growth vector for us with wireless connections growing by about 260,000 sequentially.
Now let's move to Slide 10 for our 2024 financial guidance. Here are our expectations for the year. First, we expect to again grow mobility subscribers against a healthy, but normalized industry growth. We also anticipate continued benefits from a larger subscriber base and modest growth in postpaid phone ARPUs. This should result in wireless service revenue growth in the 3% range for the full year. For broadband, we expect revenue increases of 7% plus for the full year. This growth reflects continued fiber subscriber growth and higher ARPUs from the mix shift to fiber. Overall, we expect to continue to grow consolidated revenues next year.
As we think about the EBITDA trends in 2024, we expect to grow mobility EBITDA in the mid single-digit as our disciplined approach helps us to grow valuable subscribers. In business wireline, we expect EBITDA to be down about 10% plus or minus. We expect legacy business wireline declines to be partially offset by incremental cost savings and increased fiber and fixed wireless revenues. Additionally, our guidance reflects the impact of the expected deconsolidation of our cybersecurity services business.
In consumer wireline, we expect to grow EBITDA in the mid single-digit range, thanks to continued growth in fiber revenues and to a lesser degree growth in fixed wireless subscribers. This will be partly offset by an expected continued decline in legacy copper revenues. Finally, similar to last year, we expect to benefit from ongoing corporate cost reductions again this year. These factors combined deliver consolidated adjusted EBITDA growth in the 3% range for the full year.
Moving to EPS. Here's what to think about when you do your calculations. Our full year guidance reflects non-cash headwinds of about $0.24, which include the following: $0.17 higher depreciation; approximately half is from accelerated depreciation on Nokia assets impacted by our Open RAN transformation and we expect this impact to continue through 2026. The other half is incremental depreciation from our elevated 5G and fiber builds, headwinds of approximately $0.07 associated with higher non-cash pension and postretirement benefit costs largely driven by declines in prior service credit amortization. As a reminder, prior service credit are the result of amendments made in prior years to our postretirement benefit plan that reduced benefits.
Under GAAP, the impact of these amendments is recorded as a credit and equity and amortized into income over the expected service period of plan participants. In 2023, prior service credit amortization was $2.6 billion, which is a positive contribution to other income. In 2024, we expect prior service credit amortization to be $2 billion or a decline of about $600 million. Next year, we expect a more moderate decline in prior service credit amortization, continuing to decrease in the subsequent years as prior year plan changes become fully amortized.
We have provided the projected future annual amortization by year in the footnotes of our supplemental financial trends document on our Investor Relations website. Importantly, we have continued to lower our pension obligation, including our transfer of certain pension assets and liabilities to Athene last year and we don't expect any material required contributions to our pension plans for the balance of this decade. In addition to these non-cash items, the guidance also includes $0.08 of other headwinds. These include $0.05 impact from lower spectrum related interest capitalization as we near completion of our initial C-band spectrum deployment in 2024.
We don't expect capitalized interest to be a significant headwind beyond 2024 and a $0.03 impact from lower adjusted equity income from DIRECTV, which we expect to be about $2.6 billion versus $2.9 billion in 2023. Lastly, we expect an effective tax rate in 2024 consistent with the 2023 rate. Given these assumptions, adjusted EPS for 2024 is expected to be in the $2.15 to $2.25 range. Normalizing for these four items, our 2024 guides would imply adjusted EPS growth consistent with our expected growth in adjusted EBITDA. We expect to be in a position to begin to grow adjusted EPS again in 2025.
Turning to free cash flow. Here's what to consider for 2024. First, we expect adjusted EBITDA growth in the 3% range. We also expect cash taxes to be up about $1.5 billion based on current tax law. As we look out to 2025, we would anticipate cash taxes to increase around $1 billion over 2024. Cash distributions from DIRECTV in 2023 were $3.7 billion, down about $750 million compared to the prior year. Looking forward, we expect DIRECTV cash distributions to decline at a similar rate in 2024 and thereafter. I'd also like to point out that DIRECTV's debt levels have not changed materially since the end of 2021 and its debt is non-recourse to AT&T.
Another impact to free cash flow is lower capital investment. We expect 2024 capital investment levels in the $21 billion to $22 billion range. It's also important to note that the mix shift of our capital investment continues to move in a favorable direction as vendor financing obligations decline and project capital spend increases. Accordingly, we plan to continue to pay down short-term vendor and direct supplier financings this year as we shape an even more sustainable and ratable quarterly free cash flow cadence.
Remember, our capital investments consist of payments from prior year capital spend plus current year spend. This year, there will be less payments of prior year obligations than we saw in 2023 due to significant reductions in vendor financing. However, in the year, we do expect higher spend on capital projects. When you combine all these factors, we expect to deliver free cash flow in the $17 billion to $18 billion range this year. This is greater than 2 times our current annual common dividend and more than enough to cover other commitments.
As we discussed in recent quarters, we continue to make progress on improving the ratability of our free cash flow. Last year, our free cash flow was about 70% back-end loaded to the second half. We expect that to be closer to 60% this year. Accordingly, we expect first quarter free cash flows of at least $2.5 billion. Overall, the combination of increased free cash flow and fewer one-time items will enable us to continue our deleveraging progress in 2024 and remain on track to achieve our target range of 2.5 times net debt to adjusted EBITDA in the first half of 2025.
Amir, that's our presentation. We're now ready for the Q&A.
