Thanks Mike. Good afternoon, everyone, and thanks for joining us today. I'm excited to provide an update on the significant progress we're making on Lumen's business transformation. A year ago, I shared that 2023 was a reset year for this company with new mission and vision, a new executive team, and a newly redesigned culture. And importantly, we aspired to restore confidence in Lumen, not only with improved financial results, but with execution excellence that delivers on our commitments. We outlined big, multiyear strategic priorities, including strengthening our balance sheet, executing our key programs to turn the core business around by 2025 and igniting new growth by delivering disruptive innovations that help our customers solve their next-gen networking needs. And now, I'm pleased to report that we both delivered on our 2023 EBITDA and free cash flow guidance, and we made material progress on our strategic priorities. I'll start with the balance sheet. As we announced in late January, we entered into an agreement with a significant number of our creditors that clears the path for our turnaround. The deal extends most of our debt maturities to 2029 and beyond, injects $1.325 billion of net new financing into the business and gives us access to a new approximately $1 billion revolving credit facility to support our operations. It's a strong indication of the confidence of our bondholders and the broader debt markets that they have in our strategy, and it allows us to focus our energy on executing our business transformation. All right, so how is the pivoted growth going? While we have a lot of work left to do, we're seeing progress, as evidenced by our North American business performance compared to other industry competitors. While two large legacy telco companies saw Q4 revenue declines in their business wireline segment of roughly 8% to 10% year-over-year. Lumen's business Q4 revenue decline was only 3.5% year-over-year. Breaking away from the others for the second straight quarter. We believe our positive peer group performance is due both to our strategy and our turnaround execution. Simply put, Lumen stands alone in how we think about the industry. In today's digital economy, technology environments are complex and multi-layered. Whether it's hybrid or multi-cloud or edge compute or emerging technologies like GenAI, businesses need fiber networks with digital services that deliver blazing fast speeds, ultra-low latency, massive capacity for growing data workloads and proximity to widely distributed users. All in a secure environment. While our competitors harvest their business wireline segments for cash, Lumen is building a fully digital platform to deliver important new capabilities to these customers. And importantly, we're tailoring our go-to-market approach to get them there. So let's dig a little deeper into that go-to-market execution progress. I'll start with our commercial excellence efforts in the business segment, which is all about driving better sales execution, securing our base of customers and creating a world-class digital customer experience. In 2023, we tailored our go-to-market approach to each customer segment. This focus is allowing us to meet customers where they are and provide unique and tailored paths to our modern communication infrastructure. And not surprisingly, it's driving better sales execution. This year, with a North America enterprise, we added over 3,000 customers and increased new logo sales by 13% sequentially in Q4. Specifically, our public sector segment grew double-digits quarter-over-quarter and year-over-year in Q4, powering our strong revenue performance. Year-over-year, we sold 29% more growth products to existing public sector customers in Q4 and we increased seller productivity by 18% for the full year. With this momentum, we expect this segment to be the first to bend the revenue curve back to growth, and we think bid market segment will follow suit. Since establishing the dedicated go-to-market team for bid markets last June, tenured direct sales productivity increased 26% while we simultaneously grew the sales force by 15%. Importantly, we exited 2023 by outperforming market growth rates and taking share in both SASE and IP. In our Large Enterprise segment, we're winning business with sophisticated digitally native companies like Uber, who recently chose Lumen's 400-gig wave service to ensure that they can scale and accelerate their company's growth with greater agility. Okay, let's turn to securing the base. This is all about installs, disconnects, renewals, migrations and usage. This program is the most challenging part of executing Lumen's turnaround for sure. The good news is, we're making progress in mid-markets and large enterprise, shown by our sequential results for the second half. Installations were up 13%, migrations were up 4%, renewals were up 50%, and in Q4, usage was up 3%, helping us end the year strong. Now that said, we're just not satisfied, and we'll be focusing on improving performance here in this part of our turnaround using data and analytics in AI to help determine the right action for each unique customer at the right time. The third piece of commercial excellence is all about customer experience. The Lumen operations and IT teams did a fantastic job building the digital CX foundation in 2023, redesigning our processes from order to cash, starting to implement new state-of-the-art systems and infusing GenAI into our service delivery and assurance. And while we're still in the initial stages, we're seeing signs of impact. And for example, in our North American business pilot, we were able to reduce order processing time by 70% for Dedicated Internet Access, or DIA, one of our highest volume products. And across all products for Large Enterprise and Public Sector customers, we're already seeing a 17-point year-over-year improvement in net promoter scores based on our process improvement work. Time to talk about innovation, innovating for growth. As we announced last month, Dr. Satish Lakshmanan, joined Lumen as our Chief Product Officer. Satish comes to us from AWS and brings a highly valuable combination of cloud, artificial intelligence and product development experience that will be an important part of fueling our innovation engine. And just this morning, we announced that Dave Ward is joining Lumen as our Chief Technology Officer. Dave has a long history of successful executive leadership, having served as CTO for Cisco Systems and most recently as the CEO of PacketFabric, a Network-as-a-Service provider. Talented visionaries like Satish and Dave are joining because they see the potential for Lumen to innovate, disrupt the industry and create major value for customers, and therefore major value for investors. And I'm delighted to report that we are well on our way. In 2023, Lumen co-created with customers and launched several new digital services that take advantage of our world-class fiber network. Our vision is to empower enterprises to leverage the Lumen digital platform as we are calling it, enabling customers to digitally consume our secured network services. This innovative platform will help customers build AI-powered applications across on-prem, colo and cloud environments seamlessly, while also simplifying network on-boarding and management to save costs. In the latter half of this year, we'll share new reporting for Lumen Digital to allow you to better understand our growth trajectory. Let me highlight a few important capabilities in the Lumen digital platform. First is Network-as-a-Service or NaaS. We continue to enrich our NaaS offering with more capability, and just last week we announced the availability of two new NaaS solutions with private connections. As a recent customer, Element Materials remarked, Lumen's NaaS solution was not just timely, but transformative, it highlighted the untapped potential of such innovative network solutions. Another Lumen digital breakthrough capability is ExaSwitch, our high-capacity optical switching platform originally conceived for direct inter-cloud peering. It's performing extremely well in the market and as Microsoft shared, they highly value the ExaSwitch platform for the fast and scalable interconnections that it provides and they're eager and excited to expand ExaSwitch to new metros in 2024. Lumen sees ExaSwitch as the soon to be must have solution for any corporation needing simplified, low latency, high-capacity direct cloud connectivity. Finally, Lumen Security. You may have read in the Washington Post that the Department of Justice announced it had disrupted the Volt Typhoon botnet used by a major Chinese government-backed effort to hack the US critical infrastructure. I'm incredibly proud of our Black Lotus Labs team for identifying this threat and being credited by the DOJ for helping to keep the United States safe. Soon you'll see Black Lotus Labs powering the Lumen digital platform with some highly valuable security services. Now, the initial capabilities in the platform give Lumen access to around $40 billion in net new available market. And to be clear, we're just getting started. We're bullish on the impact that Lumen Digital will have on helping pivot our company to growth. Finally, let's cover mass markets. We're executing our strategy to deploy capital where we see the greatest opportunities with the goal of continuing to evolve our business across a portfolio of markets, investing wisely and driving fiber market penetration. Some quick notes to share about 2023 in mass markets. We delivered our commitment to grow our fiber network by more than 500,000 locations and intend to maintain that similar robust rate in 2024. While we weren't happy with our net adds performance in 2023 all up, our sales and marketing engine is now gaining momentum as we close the year strongly with record-high December sales, and we continue to see this pace hold through January. Quantum Fiber is the best multi-gig product in the market and to maintain that status, we know that constant innovation is a priority. That's why we made sure we were the first company in the industry to achieve WiFi 7 certification. And finally, Quantum Fiber customers continue to be delighted as shown by our Q4 net promoter score of plus 64, improving both quarter-over-quarter and year-over-year customer satisfaction. One last exciting note. I've talked about rebuilding this company from the people up and how important culture change is to supporting our transformation. In just the fourth quarter alone, we won four different culture awards, most notably US News & World Report named Lumen Technologies one of the 2024 Best Telecom Companies to Work For. Our culture is helping us attract new talent as well as supporting our current Lumen workforce through a pretty intense time for this company. To sum it up, 2023, we made great progress pivoting Lumen for growth. We believe our strategy is the right one and we're executing well. So our plan is to hold steady on that strategy through 2024. We'll continue to strengthen our balance sheet. We'll drive commercial excellence to return the business to growth by 2025, and we'll co-create innovative new capabilities that delight customers and give Lumen access to net new profit pools. And we'll do all of that while keeping you apprised of our progress, being transparent about our wins and our struggles, and delivering on our commitments every step of the way. And with that, I'll turn the call over to Chris.
