Chris Stansbury
Executive Vice President and Chief Financial Officer at Lumen Technologies
Thanks Kate, and good afternoon, everyone. Kate spoke about our progress and how we are disrupting an industry ripe for change as Lumen transforms into the leading digital enterprise solutions provider. She also spoke of our success in reaching agreement on an amended TSA with a broadened group of creditors to extend our debt maturities.
On our Q2 earnings call, we said we viewed the formation of the creditor group as an opportunity to address a large part of the capital structure in a very efficient way, and the amended agreement we announced in January accomplishes that. The amended TSA has support from a broadened group of creditors. And when finalized, will address approximately $9 billion of outstanding indebtedness, including more than 77% of debt maturing through 2027.
The TSA transactions will extend debt maturities to primarily 2029 and beyond, provide $1.325 billion of new money and provide access to a new approximately $1 billion revolver. This agreement and the broad support for it speaks to the confidence our banks and creditors have in our plan and provides Lumen ample runway to execute on our business turnaround. In short, our capital structure is no longer a limiting factor in our transformation. We expect to complete the transactions contemplated by the TSA in the first quarter subject to the satisfaction of limited remaining closing conditions.
Before covering our fourth quarter results, I'd like to take a moment to discuss some changes to our 2024 financial reporting to enhance comparability with prior periods and better align with how we manage the business. First, we are updating our business sales channel reporting by breaking out a new international and other channel, including CDN. Secondly, given the sale of substantially all of our CDN contracts during the fourth quarter of '23, we are updating our business product category reporting to move CDN from harvest to other within the international and other channel. And finally, with the sale of our EMEA business and select CDN contracts completed in the fourth quarter of '23, we have updated our financial trending schedules to provide the historical contributions of these sales as well as the associated commercial agreement impacts. Keep in mind, when these impacts are excluded from results, our sequential and year-over-year growth rates are substantially better than the reported rates.
I'll now discuss the financial summary of our fourth quarter. Our fourth quarter total reported revenue declined 7.4% year-over-year to $3.517 billion. Approximately 39% of the decline was due to the impact of divestitures, commercial agreements and CDN. Adjusted EBITDA was $1.099 billion in the fourth quarter with a 31.2% margin. Free cash flow was $50 million in the fourth quarter. In 2023, we delivered on our expectations for both adjusted EBITDA and free cash flow.
Next, I'll review our detailed revenue results for the quarter on a year-over-year basis. Within our North America Enterprise channels, which is our business segment excluding wholesale and international and other, revenue declined 0.1%. This quarter, we had a Public Sector benefit in our other product group. As a reminder, our other category tends to fluctuate quarter-to-quarter given the nature of these revenue streams. Overall, North America business declined 3.5%. We again significantly outperformed our two largest historical competitors in the fourth quarter.
While results can vary in any given quarter, we expect this trend of divergence between performance at Lumen and the legacy business wireline providers to continue to widen over time as we expand our digital service offerings. Large enterprise revenue declined 3.6% in the fourth quarter. Large enterprise revenue was impacted by lower other product revenue and also the timing of large infrastructure revenue benefiting the year ago quarter. Our year-over-year growth rate within Grow moderated. We expect continued variability in trends as we drive toward overall stabilization.
Now moving on to mid-markets. Revenue declined 6% year-over-year. Mid-markets is a very important channel for us and one where we had lost considerable share prior to our focus and investment in this important area. We are leaning into this channel with products and buying tools to make ordering and provisioning more frictionless. As Kate mentioned, we're seeing improved leading indicators and are taking share in both IP and SASE products. This is a channel that we expect will be extremely interested in our NaaS offering given the flexibility and the ease of provisioning it provides.
Public Sector revenue grew 14.8% year-over-year. Trends improved, driven primarily by continued strength in Grow revenue, moderating declines in Nurture and higher other revenue as mentioned earlier. Over the past 12 to 18 months, investors have asked us when we will start to see the benefits of the big contracts signed with the USDA, the U.S. Postal Service, the Department of Defense and other Public Sector wins. As our results demonstrate, we are seeing revenue strength in part due to those and other deals ramping as we work diligently to deploy these mission critical services. Given our visibility to sales bookings and the longer install cycles related to the complexity of the solutions we're deploying within Public Sector, we have high confidence that we'll be the first sales channel to return to sustainable growth.
Wholesale revenue declined 11.2% year-over-year. The majority of wholesale represents the balance of trade with other carriers as we negotiate with each other on buy-side and sell-side arrangements. The historical industry behavior between carriers has been to leverage pricing and rate changes to drive results instead of delivering incremental value to customers. In our opinion, these actions are often to the detriment of the industry's customers and is also generally unhealthy for the industry, while also creating volatility in our and others results.
Within wholesale, approximately 39% of our revenue comes from Harvest products, which declined 15.9% year-over-year in the fourth quarter and contributed to a majority of the 11.2% decline. Our Harvest product revenue will likely continue to decline over time and is an area we will continue to manage for cash. International and other revenue declined 43.5% year-over-year, driven by the divestiture of our EMEA business and the sale of select CDN contracts in the fourth quarter of '23.
Moving to our business product lifecycle reporting, I'll reference results based on our North America Enterprise channels which represent our core strategic categories. Grow products revenue increased 5.7%, driven by strength in IP across all enterprise channels; cloud services and infrastructure product growth, particularly within co-location and dark fiber. Grow represented approximately 40% of our North America Enterprise revenue and for our total business segment carried an approximate 80% direct margin this quarter.
Within Nurture and Harvest, we continue to expect headwinds in these categories as we take proactive steps to migrate customers to newer technologies. These actions improve our customers experience and provide an uplift in customer lifetime value for Lumen. As Kate mentioned, we continue to see positive leading indicators that our initiatives are working and it will take some time to be reflected in our results.
Nurture products revenue declined 9.7% year-over-year. Pressure within VPN and Ethernet services drove the decline. Nurture represents about 30% of our North America Enterprise revenue and for our total business segment carried an approximate 69% direct margin this quarter. Harvest products revenue declined 10.4% year-over-year. Harvest continues to be negatively impacted by declines in TDM-based voice and other legacy services.
Now I want to take a minute to discuss Harvest in more detail. We have a very tactical approach to our Harvest portfolio, which contains a mixture of customers that are on-net as well as off-net. These off-net customer contracts carry a much different margin profile and in some cases are margin dilutive. We utilize re-rates to manage the margin, and in some cases, this can result in non-regrettable churn. In other cases, we will seek to migrate customers to our newer Grow technologies. Another set of customers within Harvest are quite profitable and their needs can be met with existing services.
Our data-driven approach drives our product migration and pricing strategies for each of these customers, enabling us to optimize our return profile. Harvest represented less than 17% of our North America Enterprise revenue in the fourth quarter, an improvement of approximately 200 basis points year-over-year. For our total business segment, it carrying approximate 81% direct margin this quarter. Other products revenue grew 31.7%. As I mentioned earlier, Public Sector showed particular strength in this product set.
Now moving on to mass markets. Revenue declined 8.3% year-over-year. Our mass markets fiber broadband revenue grew 11.5% and represented approximately a third of mass markets broadband revenue. Also, note that our exposure to legacy voice and other services revenue continues to improve with an approximate 200 basis point reduction year-over-year. During the quarter, fiber broadband enabled location adds were 126,000, bringing our total to approximately 3.7 million as of December 31.
As Kate mentioned, we intend to maintain the same 500,000 build pace this year. And during the fourth quarter, we added 20,000 Quantum Fiber customers and this brings our total to 916,000. Fiber ARPU was flat sequentially and increased on a year-over-year basis to approximately $61 in the fourth quarter. At the end of the quarter, our penetration of legacy copper broadband was approximately 10% and our Quantum Fiber penetration stood at approximately 25%. Our 12-month frozen penetration of our 2022 enablement cohort was 18% at December 31, while our 24-month frozen penetration of our 2021 enablement cohort was 25%.
Turning to adjusted EBITDA. For the fourth quarter of 2023, adjusted EBITDA was $1.099 billion compared to $1.393 billion in the year ago quarter. The fourth quarter of this year included a net headwind of $13 million related to the divested EMEA business, a net benefit of $3 million from divestiture-related post-closing commercial agreements and a net headwind of $16 million from the sale of select CDN contracts. These items represent approximately 9% of the year-over-year decline. Special items impacting adjusted EBITDA this quarter totaled $211 million. Our fourth quarter 2023 adjusted EBITDA margin was 31.2%. Capital expenditures for the fourth quarter of 2023 were $821 million and the company generated free cash flow of $50 million in the fourth quarter.
Moving to our financial outlook. For the full year 2024, we expect adjusted EBITDA to be in the range of $4.1 billion to $4.3 billion. Our EBITDA guidance includes an expected 2% to 5% organic decline, a significant and roughly 600 basis point improvement from the organic decline included in our 2023 outlook as our transformation initiatives take hold.
Moving to capital spending and our other outlook metrics. For the full year 2024, we expect total capital expenditures in the range of $2.7 billion to $2.9 billion. We expect to generate free cash flow in the range of $100 million to $300 million for the full year of 2024 and this includes an approximate $700 million tax refund received during the first quarter of this year. We expect free cash flow to be impacted by higher interest expense related to our new TSA agreement. And based on our initial analysis, we've included an incremental $125 million to $225 million of cash interest in 2024 versus 2023. We do not have any required or planned discretionary pension fund contributions in 2024.
In terms of special items for 2024, we continued to expect dedicated third-party costs to support transition services for the divestitures. The reimbursement for these services will be in other income with no material net impact to our cash flows. In addition, in the first quarter of 2024, we expect to recognize meaningful charges related to the negotiation and execution of our TSA agreement.
Before we move to Q&A, just a couple of housekeeping items. First, please remember that the first quarter typically has seasonally higher expenses related to the timing of bonus payments and other prepaid expenses. Additionally, while we are happy to discuss the recent TSA announcement in further detail, our focus is now on our business and the financial results as we move forward. Accordingly, we would prefer to be oriented to questions around the business.
With that, I'll turn over to Mike.
