Chris Stansbury
Executive Vice President and Chief Financial Officer at Lumen Technologies
Thanks, Kate. And good afternoon, everyone. As Kate described, this is a year of rapid change at Lumen. We are aggressively upgrading systems, processes and our culture as we seek to modernize Lumen to win in the marketplace and return Lumen to growth. While it's early in our journey, we are pleased with the improvements we're starting to see. A specific call-out is the significant improvement we're seeing in our Mass Markets execution, where our Quantum reassessment period allowed us to adjust our plan, and as we move forward, is proving to have been an excellent decision. As Kate said, we're back and running fast.
Before moving on to our first-quarter results, I'd like to discuss a few actions we've taken to strengthen our balance sheet to position our company to return to growth. In mid March, we announced an exchange offer for Lumen's senior notes. This deleveraging action was a win-win. During Q1, we reduced our principal debt balance by $620 million and Lumen's senior note holders that participated in the exchange received a higher coupon, as well as secured debt and a level three silo. In the first-quarter exchange transactions, we issued $915 million of level three secured bonds and Lumen's annual interest expense remains relatively unchanged. This exchange, combined with the expected proceeds from the EMEA transaction, will allow us to focus on executing against our two-year turnaround plan, which we expect will return Lumen to growth. We will continue to pursue additional opportunities to enhance our capital structure to support our long-term plan, which we expect will provide strong returns for our stakeholders.
With that, I'll discuss the financial summary of our first-quarter.
This quarter, we have expanded our reporting to include Grow, Nurture, Harvest and other by business channel. This structure includes a subtotal with Grow, Nurture and Harvest, giving visibility to our primary focus within the business channel results, excluding other. As a reminder, the other category revenue includes equipment and IT solutions, which tend to experience fluctuations due to the variable nature of these products.
Additionally, beginning this quarter and to better align with recent updates to the SEC's Reg G Compliance and Disclosure Interpretations, we will no longer report revenue, adjusted EBITDA, adjusted EBITDA margin or capex on a modified basis, which excludes the impacts of our divested businesses, as well as CAF II within historical periods. Instead, we will provide supplemental information on these discrete impacts as footnotes where applicable in our earnings presentation and a separate page in our financial training schedule. Accordingly, on this call, I will reference our financial performance primarily on a sequential basis for better comparability and to provide color on the impact of CAF II, the divestitures and commercial agreements had on select year-over-year results. It's important to note that excluding the impacts we have provided, our year-over-year growth rates are substantially better than the reported rates and are showing improvement in key areas.
Our first-quarter total revenue declined 1.6% on a sequential basis to $3.738 billion. Adjusted EBITDA was $1.251 billion in the first-quarter with a 33.5% margin. Free cash flow was negative $75 million in the first-quarter, including $90 million of taxes paid related towards two divestitures in 2022. We now expect total transaction-related taxes of around $1 billion, with the majority of the balance being paid in the second-quarter of this year from cash-on-hand. We reduced net-debt by $582 million during the first-quarter.
Next, I'll review our detailed revenue results for the quarter. Reported revenue was down 20.1% with the impact of CAF II, the divestitures and commercial agreements representing approximately 80% of the reported decline. Within our two key segments, business revenue declined 1.6% sequentially to $2.956 billion. Mass Markets revenue also declined 1.6% sequentially to $782 million. Business revenue declined 13.1% on a year-over-year basis, with the impact of the divestitures and commercial agreements representing approximately three quarters of the reported decline. Mass Markets revenue declined 38.7% on a year-over-year basis, with the impact of CAF II and the divestiture impact representing approximately 86% of the reported decline.
Within our enterprise channels, which is our business segment excluding wholesale, revenue declined 1.4% sequentially. Our exposure to legacy voice revenue continues to improve and is now approximately 11% of enterprise channel revenue and is down approximately 50 basis-points sequentially. Large enterprise revenue declined 1.9% sequentially in the first-quarter. Large enterprise revenue trends improved year-over-year when excluding the impact of divested businesses, driven primarily by IP and co-location.
Public sector revenue declined 0.2% sequentially, excluding the impacts of our divested businesses. Public sector improved significantly from the year-over-year decline last quarter on the same basis. As you know, we've had major wins in this channel over the last two years and those wins are ramping-up in revenue. You may have also seen our recent US Defense Information Systems, $223 million contract win for providing modern hybrid cloud, voice and conferencing services. Our partnership with the public sector is strong and we appreciate the confidence these entities have in Lumen and our significant capabilities to deliver these mission-critical solutions.
Mid-market revenue declined 1.3% sequentially, excluding the impacts of our divested businesses, there was a similar level of year-over-year decline compared to last quarter. Strength in IP and UC&C was offset by declines in other product categories. Wholesale revenue declined 2.2% sequentially. This is a channel that will continue to decline over-time and one we manage for cash.
Moving to our business product life-cycle reporting, Grow products revenue grew 3.4%, sequentially. Importantly, if we exclude the impacts of our divested businesses, this quarter's results showed significant improvement in year-over-year growth at close to double the quarterly sequential growth rate. While this level of improvement may not be linear as we move forward, we expect continued strength in this area as we execute on our overall pivot to growth. The Grow category now represents approximately 38% of our business segment and carried an approximate 83% direct margin this quarter. For added color, Grow products represented 58% of our enterprise sales in the first-quarter, an improvement from 4Q '22. Getting the Grow product category to grow faster is a key focus of our strategy and we're pleased with these early results.
Nurture Products revenue declined 3.1% sequentially, driven by VPN and Ethernet. We will likely face headwinds within both the Nurture and Harvest product categories as we actively work to maintain customer relationships and maximize customer lifetime value by migrating customers to newer technology solutions, Nurture now represents about 31% of our business segment and carried an approximately -- approximate 65% direct margin this quarter.
Harvest Products revenue declined 4.9% sequentially. As with Nurture, we will see headwinds in this category as we pivot customers to newer technologies with a significant focus on voice migration. Our Harvest team continues to manage these products both by extending the life of some products, while also managing customers back to Grow products. Recall that Harvest is an important part of our business and generates cash to fuel our growth initiatives. Harvest now represents approximately 25% of our business segment and carried an approximate 78% direct margin this quarter. Other products revenue declined 9.4% sequentially. As I mentioned earlier, our Other Products revenue tends to experience fluctuations due to the variable nature of these products.
Moving on to Mass Markets, revenue declined 1.6% sequentially. Our Mass Markets' Fiber Broadband revenue grew 2.7% sequentially and represented approximately 29% of Mass Markets broadband revenue. Also note that our exposure to legacy voice and other services revenue continues to improve with a nearly 60 basis-point reduction sequentially. During the quarter, total fiber broadband enablements were approximately 120,000, bringing the total fiber enabled locations to approximately 3.3 million as of March 31. We had a strong ramp in fiber enablements during the quarter. And as Keith mentioned, we are confident in our ability to meet or exceed our 500,000 new enabled locations target for 2023. We expect to continue ramping this build pace in 2024 and look forward to sharing a longer-term view at our Investor Day on June 5.
In the first-quarter, we added 24,000 Quantum Fiber customers. This brings our total Quantum Fiber subscribers to 856,000. As Keith noted, we are ramping quickly with enablement and subscriber momentum building. Our installs of fiber broadband customers exceeded our copper installs, a trend that we expect to continue to widen going-forward. Fiber ARPU was approximately $60 in the first-quarter and we see ARPU expansion opportunities with the adoption of in-home WiFi solutions, up-tiering enterprise-grade security solutions, and our recently launched multi-gig offerings, delivering up to eight-gig symmetric services. The plant we are building is capable of further cost-effective multi-gig speed enhancements going-forward. As of March 31, our penetration of legacy copper broadband was less than 12%, highlighting the significant share-taking opportunity as we accelerate the Quantum Fiber build. Our Quantum Fiber penetration stood at approximately 26%. And as we expand our footprint, we expect penetration to fall as we increase our addressable market at a higher-rate than the new customers are added.
Many investors have asked about competing Fiber activity. What we're typically seeing is activity on the distant fringes of our core growth markets. Our six core metros are hard markets to build-out, zoning and permitting hurdles, as well as the underground network infrastructure in these markets, which carries a higher build cost per location, may make other regions more appealing to competitors. While we took a small risk with our Quantum re-evaluation phase, we do not see any meaningful change in competitive activity during that short window. As our enablement and subscriber results this quarter demonstrate, we are now focused on accelerating our deployment of fiber enabled locations and adding subscribers. Our Quantum Fiber 2020 vintage frozen penetration is now above 30% and we will provide an update next quarter with our 18 month penetration rate of the 2021 vintage. Our Quantum Fiber NPS score is now greater than positive 60, an indication of the quality, value and superior service that Quantum Fiber delivers. Quantum Fiber is an all-digital, multi-gig capable prepaid product that features simple pricing with no contract, helping reduce call-center volumes and supporting our very strong NPS scores. We continue to experience no discernible change in customer payment patterns.
Turning to adjusted EBITDA. For the first-quarter of 2023, adjusted EBITDA was $1.251 billion, compared to $1.966 billion in the year-ago quarter. The first-quarter of last year included $415 million related to the divested businesses and $59 million for CAF II. And the first-quarter of this year included a negative impact of $48 million from divestiture-related commercial agreements. These items represent roughly three-quarters of the year-over-year decline. As we discussed in our fourth-quarter 2022 earnings call, EBITDA will be pressured from a year-over-year perspective, based on higher inflationary impacts, dissynergies from divested businesses, investments in growth and optimization initiatives and the impact of customer migrations as we focus on improving our customer experience with newer technologies and enhancing customer lifetime value. We incorporated these impacts into our annual guidance and are not changing those assumptions. Special items impacting adjusted EBITDA this quarter totaled $114 million. Our first-quarter 2023 adjusted EBITDA margin, excluding special items, was 33.5%.
Capital expenditures for the first-quarter of 2023 were $640 million. In the first-quarter of 2023, the company generated free cash flow of negative $75 million. As previously noted, this includes $90 million of taxes paid related to our two divestitures that closed last year. Our reported net debt was $18.876 billion.
Moving on to our 2023 financial outlook. As a result of the debt exchange offer I discussed earlier, we now expect cash income taxes to be in the range of $300 million to $400 million for the full year 2023. We anticipate offsetting this increase through our cost optimization efforts.
In closing, our team remains focused on executing on our growth initiatives to drive long-term profitable revenue growth. We look forward to sharing more about our strategy and our path to growth with you at our investor day on June 5.
With that, we're ready for your questions.
