Chris Stansbury
Executive Vice President, Chief Financial Officer at Lumen Technologies
Thank you, Kate, and good afternoon, everyone. Kate spoke about our progress in transforming and disrupting telecom and playing to win. She also spoke of our success in reaching an agreement with a 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 both fund our future as well as address our challenging maturities profile. The agreement we announced today meets both of those objectives and will allow us to continue our transformation journey and the disruption of telecom.
Before covering our third quarter results, I would like to take a few minutes to discuss several items which will impact our financial trends going forward. As Kate mentioned, we closed the CDN sale earlier this month, and we expect to close the sale of our EMEA business tomorrow, November 1.
The CDN sale will not have a material impact on our financials. We estimate that these CDN contracts contributed roughly $20 million in revenue and $10 million in adjusted EBITDA to our third quarter 2023 results. Keep in mind that these CDN contracts were part of our Harvest portfolio, and have received little capital investment in recent years. The valuation, while not disclosed, reflects the declining nature of the revenue of these contracts. We plan to wind down the remaining CDN contracts in 2024. For the pending divestiture of our EMEA business, our 2023 outlook assumed a full fourth-quarter contribution of approximately $140 million in revenue, $50 million in adjusted EBITDA, and $30 million in capex. Separately, we are expecting a tax refund of approximately $900 million previously not included within the financial outlook. Approximately $200 million of the refund will be applied to pay 2023 estimated taxes, and we are expecting a cash refund of approximately $700 million in the first quarter of next year.
While we expect to receive a near-term cash benefit, this is in part due to an accelerated use of our NOLs. Some of the benefits will reverse over the next few years. There are counterbalancing impacts related to the CDN contracts and the pending EMEA transaction that make us comfortable keeping our full year 2023 free cash flow guidance of $0 to $200 million.
As Kate mentioned, the macro environment and the overhang of our creditor discussions has resulted in revenue headwinds, which will pressure our results over the next few quarters. With the creditor agreement reached today and continued execution against our plan, we expect to see sustained improving revenue trends in mid 2024.
In addition, we expect the cost actions that Kate mentioned earlier to help address near-term pressures on adjusted EBITDA. Additionally, we've been clear that in the wake of transactions over the last year and a half, our organization needs to be more nimble and continue to work through transaction-related dyssynergies.
I'll now discuss in more detail the financial summary of our third quarter. As I've done throughout this year, I'll reference our financial performance primarily on a sequential basis for better comparability as the year-ago period included the impacts of our divested LATAM and ILEC 20-state businesses.
Keep in mind, when the impacts of divestitures and commercial agreements are excluded from results, our year-over-year growth rates are substantially better than the reported rates.
Our third-quarter total revenue declined 0.5% on a sequential basis to $3.641 billion. Adjusted EBITDA was $1.049 billion in the third quarter with a 28.8% margin. Free cash flow was $43 million in the third quarter.
Next, I'll review detailed revenue results for the quarter. On a year-over-year basis, reported revenue was down 17.1% with the impact of divestitures and commercial agreements representing approximately 73% of the reported decline. Within our two key segments, business revenue declined 0.1% sequentially to $2.894 billion, and Mass Markets revenue declined 2.2% sequentially to $747 million.
Within our Enterprise channels, which is our business segment excluding wholesale, revenue grew 1.1% sequentially. Be aware that much of this strength is driven by growth in other products, which tend to fluctuate quarter to quarter. However, excluding other products and the impact of divested businesses, our subtotal of grow, nurture, and harvest revenue declined at the slowest rate we've seen in years. That said, we continue to expect near-term variability in the revenue trends.
Our exposure to declining harvest revenue is now less than 18% of Enterprise channel revenue and was down approximately 70 basis points sequentially. Large Enterprise revenue grew 0.3% sequentially in the third quarter. Large Enterprise revenue trends improved compared to the second quarter year over year when excluding the impact of divested businesses driven primarily by continued strong trends in the Grow products segment due to demand for IP, dark fiber, and colocation and moderating declines in Nurture and Harvest.
Now, moving on to public sector. Revenue grew 7.2% sequentially. Excluding the impact of our divested businesses, public sector trends improved year over year primarily due to higher other revenue, which includes nonrecurring equipment and IT solutions, improvement in Grow revenue, and moderating declines in Nurture and Harvest products during the third quarter. Mid-market revenue declined 1.8% sequentially. Excluding the impacts of our divested businesses, third-quarter revenue trends worsened year over year. Strength in Grow products were driven primarily by IP, UC&C, and enterprise broadband, which is more than offset by lower VPN revenue within Nurture.
Wholesale revenue declined 3.4% sequentially. We expect our wholesale channel will likely continue to decline over time as it is an area we manage for cash. Now, moving on to business product life cycle reporting. Grow products revenue declined 1.1% sequentially.
Excluding the impacts of our divested businesses, this quarter's results showed moderating year-over-year growth. While results can vary in any given quarter, we expect sustained strength in this area as we execute on our turnaround.
Grow continues to represent approximately 39% of our Business segment and carried an approximate 82% direct margin this quarter. Within Nurture and Harvest, we expect -- we continue to expect headwinds in these categories as we take proactive steps to migrate customers to newer technologies.
This improves our customers' experience and provides an uplift in the lifetime value of those customers 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 product revenue declined 0.5% sequentially due to continued pressure in VPN and Ethernet services. Nurture represents about 30% of our business segment and carried an approximate 69% direct margin this quarter.
Harvest products revenue declined 3.8% sequentially. Recall that Harvest is an important part of our business as it generates cash to fuel our growth initiatives. Harvest represents approximately 24% of our business segment and carried an approximate 80% direct margin this quarter. Other products revenue grew 23.7% sequentially. Our other product revenue tends to experience fluctuations due to the variable nature of these products.
Now, moving on to Mass Markets, revenue declined 2.2% sequentially. Our Mass Markets fiber broadband revenue grew 3.2% sequentially and represented approximately 32% of Mass Markets broadband revenue. Also note that our exposure to legacy voice and other service revenue continues to improve with a nearly 20-basis-point reduction sequentially.
During the quarter, total fiber broadband enablements were 141,000, bringing the total fiber-enabled locations to approximately 3.5 million as of September 30. During the third quarter, we added 19,000 Quantum Fiber customers. Fiber ARPU was flat sequentially and increased on a year-over-year basis to approximately $61 in the third quarter.
At the end of the quarter, our penetration of legacy copper broadband dropped below 11% and our Quantum Fiber penetration stood at approximately 25%. The agreements with our creditor groups have given us runway to execute against our turnaround plan but those agreements will result in interest expense increasing sooner than our forecast had anticipated. This leads to a choice of higher enablements or higher returns for the Mass Market business, and we are choosing higher returns. We will continue to build at a pace similar to what we're doing this year, but we'll increase our focus on driving penetration and ARPU, and growth.
As I've said many times, our best use of incremental investment is in our Business segment where we see faster and better returns.
Turning to adjusted EBITDA for the third quarter of 2023, adjusted EBITDA was $1.049 billion compared to $1.688 billion in the year-ago quarter. The third quarter of last year included $332 million related to the divested businesses, and the third quarter of this year included a negative impact of $40 million from divestiture-related commercial agreements. These items represent approximately 58% of the year-over-year decline.
Special items impacting adjusted EBITDA this quarter totaled $33 million. Our third quarter 2023 adjusted EBITDA margin excluding special items was 28.8% as we lean into growth and optimization efforts. Capital expenditures for the third quarter of 2023 were $843 million.
In the third quarter of 2023, the company generated free cash flow of $43 million. Now, moving on to our outlook. Our financial outlook for 2023, we are reiterating all guidance metrics. We'll provide our outlook for 2024 when we report our fourth-quarter results in early February.
With that, we're ready for your questions.
