Senior Executive Vice President, Chief Financial Officer at AT&T
Thank you, John, and good morning, everyone. As you know, we typically provide a brief review of our subscriber trends at this point in our prepared remarks. But today, I'd like to zoom out and connect the dots on the progress we've made so far on our multiyear journey to reposition our core operations. Our goal has been to take advantage of the expected increase demand for wireless and broadband connectivity by adding customers the right way, with a focus on long-term value. We recognize that in order to do that, we had to increase our investments in the business to enhance our customer value proposition and make more memorable and lasting connections with our customers. We understood that these investments would have a short-term impact on wireless ARPU and profits, but over time, would build durable customer relationships and deliver attractive returns.
Over the last few quarters, you've started to see the full picture and the results of these efforts. In Mobility, our largest business unit, we're growing subscribers and taking share. We also continue to see very healthy ARPU. This translates to growth in wireless service revenues and EBITDA, while improving margins. We've grown both revenues and EBITDA year-over-year for four consecutive quarters, and this past quarter was the best first quarter for Mobility EBITDA in the company's history.
In Consumer Wireline, we've invested to increase our fiber footprint to provide customers with best-in-class access technology. Over the course of the past three years, we added about 6 million fiber locations that we can now serve. By doing this, we successfully transformed a business that was in secular decline into a growth business, with fiber growth outpacing legacy wireline declines. The consistency of our results across 5G and fiber provides us with confidence that our go-to-market approach is both sustainable and delivers attractive returns. These results are the outcome of the hard work our teams have done and show the value in what we've been working towards the last three years, and now it's about continuing to deliver quality growth with attractive returns. So again, we're clearly growing the right way and focused on the long term.
Now, let's turn to our first quarter financial summary on slide six. Consolidated revenues were up 1.4% in the first quarter, largely driven by wireless service revenues and to a lesser extent, Mexico and Consumer Wireline. This was partially offset by an expected decline in Business Wireline as well as lower mobility equipment revenues. Adjusted EBITDA was up 3.9% for the quarter as growth in Mobility, Mexico and Consumer Wireline were partially offset by an expected decline in Business Wireline.
Adjusted EPS was $0.60 compared to $0.63 in the year ago quarter. In the quarter, there were about $0.06 of aggregated EPS headwinds from higher pension, lower DIRECTV equity income and higher effective tax rate. This was partially offset by strong growth in Mobility. Cash from operating activities came in at $6.7 billion versus $7.6 billion last year. This was largely due to the timing of working capital, which includes lower securitizations. As a reminder, the first quarter is typically the high watermark for device payments, and we expect payments to progressively get lower as we make our way through the balance of the year.
Capital investments were $6.4 billion as we continue to make historically high levels of investments in 5G and fiber. Free cash flow for the quarter was $1 billion. This was consistent with our expectations and accounts for several seasonal and anticipated working capital impacts. We remain confident in our full year outlook for free cash flow of $16 billion or better. This expectation is largely due to the timing of capital investments, device payments, incentive compensation, which all peaked in the first quarter.
Now, let's look at our Mobility operating results on slide seven. Before we get started, we disclosed in early March that we modified our business unit reporting and no longer record prior service credits to our individual business units. Prior period business unit results have been recast for this change. There is no impact to consolidated the operating income, as price, service, credit continue to be recorded in other income.
Looking at our Mobility results. Revenues were up 2.5% and service revenues were up 5.2% driven by subscriber growth and higher ARPU. Mobility EBITDA was up $621 million or 8% for the quarter, driven by growth in subscribers, service revenue and the assets of 3G network shutdown costs versus the first quarter of 2022. Mobility postpaid phone ARPU was $55.05 up $1.05 or nearly 2% year-over-year. ARPU growth remains largely driven by higher ARPU on legacy plans from last year's pricing actions, a continued mix shift to higher-value rate plans and a continued improvement in consumer international rolling trends.
Postpaid phone churn remains low at 0.81% for the quarter. We believe our team's ongoing success can be largely attributed to the consistent investment we've made to build a fast and reliable 5G network and the actions we've taken to ensure our customers feel valued and appreciated. In prepaid, we had 40,000 phone net additions. Our total prepaid churn was below 3%, primarily driven by loyalty from Cricket customers who stayed with us as a result of our value and reliability. Overall, I'm really pleased that the team achieved solid subscriber growth even against a moderation in industry demand.
I'd like to also quickly acknowledge the strong results posted by our team in Mexico. We're very pleased with the performance of our Mexico wireless operations, which boosted strong revenue and steady profit growth, thanks to improved operational execution and scale.
Now let's move to Consumer and Business Wireline results, which are on slide eight. Let's start with Consumer wireline where our growth was led by our investment in fiber, which is consistently yielding strong returns. We added 272,000 fiber customers in the quarter. This speaks to the quality of the service we're providing and the continued demand for the best Internet technology available today. With our fiber subscribers now outnumbering our non-fiber subscribers, the increasing mix shift from legacy products to fiber continues to drive strong broadband results.
Broadband revenues grew by more than 7% year-over-year, including accelerated year-over-year fiber revenue growth of more than 30%. Fiber ARPU was $65.92, up more than $1 sequentially, with ARPU for new fiber customers at about $70. Customers are increasingly choosing to take advantage of the benefits offered by faster speed tiers, which is also supporting ARPU growth.
Consumer Wireline EBITDA grew 3.2% for the quarter due to growth in fiber revenues and transformation savings, partially offset by higher storm costs on the West Coast, which hurt growth by about 250 basis points in the quarter. Overall, we could not be more confident in the future of our Consumer Wireline business, with fiber well positioned to lead our growth in the decade ahead.
Turning to Business Wireline. EBITDA was down $230 million year-over-year, which was in line with our expectations. This was partially driven by about $50 million in year-over-year comparability factors, including favorable compensation adjustments in the first quarter of last year. Our rationalization process in Business Wireline also continues as we remain focused on the opportunities that 5G and fiber expansion create, particularly in the small and midsized business category.
Our Business Solutions wireless service revenues grew nearly 7% despite a moderation in industry growth as we continue to grow faster than our peers. One driver of this growth continues to be FirstNet, where wireless connections grew by about 300,000 sequentially, about 40% of which are postpaid phones. Ultimately, we're making progress on transforming our Business Wireline operations. And when we normalize out for one-time comparison items in the quarter, we still see the same underlying trends and continue to expect full year results aligned to what we guided in January.
Now to wrap up my comments. I'll restate that we embedded expectations for a comparatively slower macro backdrop in our full year outlook and therefore, remain on track to deliver on our full year guidance. We will continue to monitor the economy closely. And if we find ourselves operating in a more challenging macro environment than we anticipated, there are levers to pull. Ultimately, we feel like we have found the right formula to deliver sustainable results with profitable 5G and fiber subscriber gains. We've demonstrated this by growing consolidated EBITDA, improving ARPUs and growing broadband and wireless service revenues, with consistently low postpaid phone churn, and we are confident that this formula will continue to work.
Amir, that's our presentation. We're now ready for the Q&A.
