Thank you, Chuck, and good morning, everyone. Before getting started on the overview of our financial results, I wanted to thank Chuck and the Board for giving me the opportunity to become CommScope's Chief Financial Officer. I'm very excited by the prospect of working with the entire management team as we continue our efforts to transform the business.
My primary responsibility since joining CommScope a year ago has been to lead the transformation office and the CommScope NEXT initiative. From this perspective, it has become clear to me that CommScope has tremendous potential to create shareholder value.
As we now move into the full implementation phase of CommScope NEXT, a key component of my role as CFO and a critical requirement for success will be ensuring that we have tight linkage between the financial oversight function and the goals of CommScope NEXT. Clear and transparent financial management processes, combined with effective tools for tracking progress and driving accountability, will also be critical performance drivers going forward.
I'm now turning to Slide 3 for an overview of our consolidated results. During the third quarter, regarding the consolidated business, net sales decreased 3% to $2.11 billion. Orders for the quarter were $2.34 billion, yielding a book-to-bill ratio of 1.1x.
Adjusted EBITDA of $259 million decreased 24%, and adjusted EBITDA margin was 12.3%. Adjusted EBITDA included a $12.7 million charge for bad debt expense related to one customer in the Home Network segment. Adjusted earnings per share was $0.29 per share and decreased 43% from the prior year period.
Shifting focus to our core CommScope businesses, net sales increased 6% in the quarter to $1.69 billion. Core adjusted EBITDA declined 12% from prior year to $275 million, while adjusted EBITDA as a percentage of sales was 16.2%. I'd remind you that the third quarter of last year benefited from a significant Broadband Networks software license sale of approximately $25 million. Normalizing for this item, year-over-year net sales would have increased 8%, and adjusted EBITDA would have declined more modestly at around 4%.
Orders for the core business were again very solid, yielding a core book-to-bill ratio of over 1.1x. Our core business backlog remains strong at more than $2.2 billion and is up 61% year-to-date. As Chuck mentioned, despite solid growth in the quarter, the entire company continues to be impacted by significant challenges related to the global supply chain environment. It should be noted that on a year-to-date basis, despite a difficult cost and component availability environment, core CommScope net sales were ahead of prior year by 11% and adjusted EBITDA by 10%.
Turning to Slide 4 for an overview of the supply chain situation. CommScope is feeling the impacts of the challenging global supply chain environment. We are a technology company that is very dependent on the supply of key electronic components as well as a manufacturer of products with high content of various commodity and freight inputs. As a result, component shortages in commodity and freight inflation are having significant revenue and cost impacts across all our business segments.
Component shortages and, in particular, semiconductors, had a meaningful impact on our ability to deliver on the strong customer demand we continue to see during the third quarter. On a full year basis, if we had a normal supply of electronic components with no shortages or delays, our order flow would have been able to support approximately $600 million of incremental revenue to what we now expect to ship for 2021. Of this amount, approximately $260 million is related to our core business and the remainder of approximately $340 million is attributable to Home Networks.
As Chuck mentioned earlier, in addition to component shortages, we continue to experience significant inflationary headwinds that we're actively working to mitigate. These impacts have been most severe in the areas of key input commodities such as copper, steel, aluminum, resin, electronic components and freight costs. While we have been dealing with input price inflation since the beginning of the year, these impacts accelerated during the third quarter. The net impact of input costs and freight inflation on the third quarter adjusted EBITDA in our core business was approximately $70 million.
Although these inflationary increases may end up being transitory, the negative impact they are having on our business requires that we take significant mitigating actions now. We have already started to increase prices to offset some of these impacts, and we will be implementing additional price actions across all our businesses throughout the balance of 2021 and into 2022. We will also continue additional cost and operational measures to supplement our pricing actions. Our goal will be to fully offset our input and freight cost increases.
However, given the size of our backlog as well as the terms of our sales contracts, we are not targeting a full recovery of these impacts until the end of 2022. This implies that we will continue to feel the impact of supply chain disruptions on our financial results into 2022 with a gradual recovery of profitability throughout the year.
To further highlight the impact that inflation is having on our business, we can provide the following data. While we expect core revenue to grow mid-single-digit percent year-over-year in the fourth quarter, due to continuing supply chain pressures, we are expecting the fourth quarter of 2021 to be roughly $50 million to $60 million lower than the third quarter on an adjusted EBITDA basis for the core business.
Turning to Slide 5 for an overview of our segment highlights and beginning with the Broadband Networks segment. Net sales of $780 million declined 4%, primarily driven by North America and Asia Pacific regions. While we continue to see growth in our Network, Cabling and Connectivity business, this was offset by declines in Access Technologies and Converged Network Solutions.
Adjusted EBITDA of $158 million declined 22%, primarily driven by lower sales volumes and rising input costs. We also faced a difficult compare in the third quarter due to a large high-margin software license sale that did not repeat. Despite supply constraints and commodity cost inflation, on a year-to-date basis, Broadband revenues and adjusted EBITDA were up 14% and 18%, respectively.
Overall demand in the business continues to be solid with our backlog for Broadband Networks over 50% more than the prior year. This continued growth -- demand growth and backlog build is particularly apparent in our Network Cabling and Connectivity business. This business unit continues to benefit from a variety of fiber expansion projects by cable operators and telcos as well as government broadband stimulus. We expect this growth to continue as operators push fiber deeper into networks and as the release of RDOF funds accelerates.
As Chuck noted, during the third quarter, we continue to see a strong trend of cable operator investment in existing networks as well as continuation of the gradual trend of adopting distributed access network models. We expect the investment cycle in existing networks to have a long tail, and we are equally well positioned to serve those operators making the transition to network architects.
Finally, we expect to benefit from continued investment by operators into driving fiber deeper into networks as well as an accelerating pace of greenfield fiber network builds.
Turning to Venue and Campus Networks on Slide 6. Net sales of $555 million increased 8% with strength across all regions. Segment growth was driven by our business connectivity infrastructure business unit, which supplies indoor copper and fiber cabling for enterprises and data center customers. This growth was partially offset during the quarter by net sales declines at RUCKUS and in our DAS and Small Cell business unit.
Adjusted EBITDA of $56 million is modestly due to a combination of volume increase and early progress on pricing initiatives, offset by input cost inflation. Backlog versus prior year period increased by over $430 million or 159%. And since the beginning of the year, backlog has increased by 148%. Without supply constraints, we would have shipped approximately $65 million of additional products in the quarter.
Our business connectivity infrastructure unit drove the overall segment growth for the quarter. Within the business unit, we continue to see a post-COVID recovery of commercial real estate and infrastructure project activity that is supporting new spending on indoor copper and fiber cabling. These product lines also benefited from continued government stimulus spending for education and health care-related connectivity projects.
We were also able to make solid progress during the quarter with various pricing initiatives designed to recover commodity impacts on our cabling product lines. In addition to the above, demand for indoor fiber products from data center customers remains robust with strong momentum in expansion and upgrade-related spending by multi-tenant enterprise and hyperscale data centers.
In our distributed antenna systems business, 4G- and 5G-related venue upgrades remain a key driver of incremental sales. During the quarter, as has been the case throughout 2021, we saw a steady progression of smaller upgrade projects related to hospitals, airports and entertainment venues as opposed to large-scale stadium deployments that we executed during 2020.
And our OneCell business unit continues to scale up, driven by several more 4G sites going on air. We're also expanding our 5G engagements with customers as we look to deploy solutions for both public and private networks.
Finally, the technology evolution to WiFi 6 and 6E and government stimulus spending are driving very strong demand and backlog growth in our RUCKUS business. We are also seeing a recovery in the hospitality vertical as a pickup in both business and tourist travel is driving hotel operators to upgrade their networks.
RUCKUS also benefited during the third quarter from healthy demand from multi-dwelling unit and educational verticals. Despite these encouraging demand trends, RUCKUS sales were materially impacted during the third quarter by semiconductor shortages that limit our ability to ship WiFi access points and campus switches to customers at a rate that matched our order inflow.
Turning to Outdoor Wireless Networks on Slide 7. Net sales of $356 million increased significantly, up 31% from prior year, driven primarily by North America. From a business unit perspective, we saw the greatest revenue benefit from our diverse portfolio of macro cell tower infrastructure solutions.
Segment adjusted EBITDA of $61 million increased 13% over prior year and was primarily driven by higher volumes, partially offset by input cost inflation and freight increases. Outdoor Wireless performance during the third quarter was largely driven by continued ramping of telco operator investment spending to upgrade macro cell sites for 5G service.
As operators focus on macro cell site preparation, we are seeing healthy global demand for a wide variety of Outdoor Wireless products. Our Outdoor Wireless segment's backlog remained strong, which is a trend we have seen for much of 2021. We believe that this backlog is very solid with some visibility into 2022.
During the third quarter, we saw a continued demand from telco operators for our suite of base station antennas, but also for cell site infrastructure solutions such as HELIAX cabling, structural steel, cabinets and power management solutions. As heavier and more power intensive equipment is added to the macro site, wind loads, power regulation and operating costs become more important considerations and should continue to benefit CommScope's broad, everything but the radio portfolio of products for macro cell sites.
We also continue to be encouraged by operator interest in our active/passive hybrid antenna collaboration with Nokia and its potential to simplify 5G deployments. And we expect to have more news to share about this exciting technology evolution in the coming months.
Stepping outside of North America, during the quarter, we made strong progress in several international markets, securing a base station antenna win at a major European operator and making new headway as a potential important player in Japan's 5G network infrastructure.
Turning to Slide 8 for our Home Networks segment. Net sales of $415 million declined 28% year-over-year and in all regions, except for Asia Pacific. From a business unit perspective, sales declined in both video and broadband gateway product lines.
Adjusted EBITDA of negative $16 million declined $46 million from the prior year, which include the impact of bad debt expense. The profitability decline was driven most significantly by lower volumes and higher input costs. Home Networks products rely heavily on semiconductor chips, and our inability to source chips in the required quantity continues to materially impact the ability of Home Networks to deliver products to serve the demand we are seeing.
Home's profitability was also negatively impacted by rising component input and freight costs, in addition to expedite fees. On the positive side, Home Networks continues to build strong and high-quality backlog, and our visibility for orders now extends well into 2022. Selling price increases have been announced and are being implemented to offset the inflationary costs.
As an update on the Home Networks spin-off, we are continuing to make progress on separating the business from core CommScope and expect to execute the spin-off as planned during the second quarter of 2022.
Now turning to our cash flow overview on Slide 9. For the third quarter, cash flow from operations generated $67 million, and adjusted free cash flow was $64 million. For the quarter, we saw nearly $110 million of inventory increases, however, this was roughly offset by other working capital changes. Given the supply chain issues that we have discussed today, we expect our levels of inventory to remain elevated until supply disruptions improve. This is due primarily to extended transit times of our inputs and finished goods and the need to hold higher inventories of certain components to offset supply volatility.
Considering the above as well as lower EBITDA, driven by supply constraints and input cost inflation, we now expect full year cash flow generation to remain softer than originally expected. This situation should gradually improve as we realize the effects of our initiatives to offset inflation. In the meantime, we will continue to prudently manage cash and working capital.
Turning to Slide 10 for an overview of our liquidity and capital structure. During the third quarter, we continue to take steps to proactively manage and derisk our balance sheet. We successfully refinanced $1.25 billion of secured notes due in 2024 with a new 8-year tranche of secured notes due in 2029. This refinancing pushed out a large tranche of debt and extended our next debt maturity to 2025. It also reduced our interest rate on this tranche of debt by 75 basis points and lowered annual interest expense by over $9 million.
During the third quarter, our cash and liquidity once again remained strong. We ended the quarter with over $411 million in cash and no outstanding draws under our ABL. The company's total available liquidity was nearly $1.1 billion. We made no significant net debt repayments during the quarter beyond the required $8 million of term loan amortization.
The company ended the quarter with net leverage of 7.1x, an increase from 6.6x at the end of the second quarter. We remain committed to our longer-term goal of significantly reducing leverage and expect to provide insight into our path and timetable toward this goal as we refine our CommScope NEXT strategy around cost efficiency and growth.
I will now turn the call back to Chuck.
