Pascal Desroches
Senior Executive Vice President and Chief Financial Officer at AT&T
Thank you, John, and good morning, everyone, and let's start by reviewing our first quarter financial summary on Slide 7.
In the first quarter, revenues were down slightly as a decline in low margin mobility equipment revenues and business wireline revenues offset growth in high margin wireless service revenues and fiber revenues.
Adjusted EBITDA was up 4.3% for the quarter, as growth in mobility, consumer wireline in Mexico were partially offset by continued decline in business wireline. For the full year, we still expect adjusted EBITDA growth in the 3% range.
Adjusted EPS was $0.55 compared to $0.60 in the year ago quarter. In the quarter there were about $0.11 of aggregated EPS headwinds from four items we discussed last quarter. These include higher depreciation, higher non-cash postretirement benefit costs, lower capitalized interest, and lower equity income from DIRECTV. For the full year, our expectations remain for adjusted EPS of $2.15 to $2.25.
First quarter free cash flow of $3.1 billion was up more than $2 billion compared to last year. The important takeaway is that improved conversion of EBITDA to free cash flow has allowed us to pay down short-term supplier obligations. The paydown of this facility should allow us to continue to drive more ratable quarterly free cash flow.
Cash from operating activities came in at $7.5 billion versus $6.7 billion last year. As a reminder, the first quarter is typically the high watermark for device payments, and we expect payments to get progressively lower throughout the year.
Capital investment for the quarter was $4.6 billion, down about $1.8 billion compared to the prior year. Capital expenditures were $3.8 billion, compared to $4.3 billion in the prior year.
Now let's look at our mobility operating results on Slide 8. The wireless industry remains healthy, and our mobility business continues to deliver strong results, driven by our consistent go to market strategy and solid execution. For the quarter, we reported 349,000 postpaid phone net adds. We grew service revenue by 3.3%, which included the impact of customer credits. This was offset by lower equipment revenues with postpaid upgrade rate of 3%, which was down from 3.7% last year.
We continue to expect wireless service revenue growth in the 3% range for the full year. Mobility EBITDA grew 7%, or about $600 million year-over-year, which exceeded service revenue growth on a dollar basis. This demonstrates we're significantly improving operating leverage and highlights the efficiency of our consistent go to market strategy, which has enabled us to take costs out of the business. We now expect our mobility EBITDA to grow in the higher end of the mid-single digit range this year, driven by better-than-expected performance with business wireless customers and continued disciplined cost management.
Our postpaid phone ARPU was $55.57. This was up nearly 1% year-over-year, largely driven by higher ARPU and legacy plans. For the year, we continue to expect modest postpaid phone ARPU growth.
Now let's move to consumer wireline results on Slide 9. Our growth in consumer wireline was led once again by our fiber subscriber growth, which has consistently yielded strong returns. In the quarter, we had 252,000 AT&T fiber net adds, which is in line with the outlook we provided. This is the 17th consecutive quarter with AT&T fiber net adds above 200,000. We now have fiber penetration of 40% with several markets well above that level.
Broadband revenues grew 7.7% including strong fiber revenue growth of 19.5%. For the full year, we continue to expect broadband revenue growth of 7% plus, Fiber ARPU of $68.61 was up more than 4% year-over-year with intake ARPU remaining above $70.
Consumer wireline EBITDA grew 14.6% due to growth in broadband revenues and ongoing cost transformation. We now expect consumer wireline EBITDA to grow in the mid to high single digit range this year, driven by continued strong fiber revenue growth and disciplined cost management, partially offset by continued legacy copper declines.
As our customer base continues to migrate to fiber from legacy services, our broadband support cost [Phonetic] are decreasing thanks to fiber's more efficient operating model, greater reliability and higher quality service. And while fiber remains our focus and lead product, we continue to be encouraged by the early performance of AT&T Internet air, our targeted fixed wireless service, which is available in parts of 95 locations. We now have more than 200,000 AT&T Internet air consumer subscribers, having added 110,000 in the quarter. Ultimately, we couldn't be more excited about the future of consumer wireline with AT&T fiber well positioned to lead our growth and AT&T Internet air, helping us provide quality broadband service to customers, where we don't offer fiber.
Now, let's cover business wireline on Slide 10. Business wireline EBITDA was down 16.5% due to faster than anticipated rate of decline for our legacy voice services. At the start of the year, we shared that we expected business wireline EBITDA trends to improve on a full year basis. However, due to faster than expected decline of legacy voice services, we now expect full year business wireline EBITDA declines in the mid teens range versus our prior outlook of a decline of 10%, plus or minus.
As John mentioned, we're advancing several cost saving and productivity initiatives. This should benefit results in the second half of the year when we also have more favorable year-over-year comparison. As we transition this business, we believe our 5G and fiber expansion presents plenty of growth opportunities. We're already seeing this in some of the parts of our broader business solution results today. A great example is FirstNet, where wireless connections grew about 320,000 sequentially. We're also pleased with early demand for AT&T Internet air for business, which we expect to benefit results in the second half of the year.
Now let's move to Slide 11 for an update on our capital allocation strategy. Our approach to capital allocation remains deliberate. We're successfully balancing long-term network investment to fuel sustainable subscriber and service revenue growth, paying down debt and returning value to shareholders. We remain on track for full year capital investments in the $21 billion to $22 billion range versus approximately $24 billion in 2023. While our overall capital investment will be lower in 2024 compared to recent years, we continue to invest in key growth areas, given the compelling returns on these investments.
In mobility, we are focused on modernizing our network through our Open RAN initiative and with fiber, we remain on track to pass 30 million plus consumer and business locations by the end of 2025. As we've stated before the better-than-expected returns, we're seeing on our fiber investment potentially expands the opportunity to go beyond our initial target by roughly 10 million to 15 million additional locations. This also assumes similar build [Phonetic] parameters and a regulatory environment that remains attractive to building infrastructure.
It's important to note that as we continue to build out our network this year, we expect to have lower vendor financing payments, while increasing the total investment we make directly into our networks, as we continue to invest in fiber expansion and wireless network transformation. In other words, we expect our total capital investment and capital intensity to decline this year even, as we boost investments in our network.
We also remain laser focused on deleveraging. Over the last four quarters, we reduced the debt by about $6 billion. At the end of March, net debt to adjusted EBITDA was 2.9 times, and we're making steady progress on achieving our target in the 2.5 times range in the first half of 2025.
As I mentioned last quarter, we expect to address near-term maturities with cash on hand, and this quarter, we repaid $4.7 billion of long-term debt maturities. Looking forward, our debt maturities are very manageable, and we are in a great position with more than 95% of our long-term debt fixed with an average rate of 4.2%.
In addition to paying down debt, we reduced vendor and direct supplier financing obligations by about $2.3 billion during the quarter. This was partially offset by $400 million in additional proceeds on our securitization facility. These efforts highlight the quality of the free cash flow we're delivering.
DIRECTV distributions in the quarter were $500 million compared to $1.3 billion in the first quarter of 2023. For the year, and thereafter, we continue to exact DIRECTV cash distributions to decline at a similar rate to 2023 or by about 20% annually.
With $3.1 billion in first quarter free cash flow, we've dramatically improved our free cash flow ratability just as we committed, we would last year. Looking forward, we still anticipate generating approximately 40% of our total 2024 free cash flow in the first half of the year and continue to expect full year free cash flow of $17 billion to $18 billion range.
To close, I'm really pleased with our team's overall performance in the quarter. Despite managing through legacy declines, our strength in mobility and consumer wireline has us on pace to deliver on our full year consolidated financial guidance.
Brett, that's our presentation. We're now ready for the Q&A.
