As a result, ATN today is a stronger, more resilient company. We concluded a solid 2023, with a strong fourth quarter, executing on our First-to-Fiber and Glass and Steel investment strategy. Our continued conversion of customers to our high-speed networks and focus on margin improvement contributed to subscriber growth, higher revenue and margin expansion. In fact, both the quarter and the year, we achieved single-digit revenue growth and double-digit expansion of adjusted EBITDA. Justin will expand more on our financial results shortly, but first, I'd like to start with four key points that frame our 2023 performance and the opportunities ahead for ATN. First, in 2023, we executed several important strategic milestones that are key to our success going forward.

We advanced our First-to-Fiber and Glass and Steel investment strategy by adding fiber-rich digital infrastructure in the markets we serve. In May, we announced our long-term agreement with Verizon. We have made strong progress towards our multiyear effort to transition our large carrier customers from legacy wholesale roaming services to carrier managed services that provide ATN with greater revenue stability. We completed the integration of Sacred Wind, a core addition to our operations, and expanded our business and retail broadband operations domestically. In 2023, we also completed initiatives to right size operations to better support the business into the future. These actions are now complete in the U.S. and essentially completed internationally.

All in all, we have enhanced our capabilities to better serve our customers and provide high-quality, reliable products and services for the coming years. As a result of these combined efforts, ATN is operating from a strong and scalable foundation as we enter 2024. Second, our First-to-Fiber and Glass and Steel infrastructure investments are yielding results across key operational metrics. Expanding high-speed network reach and capabilities provides a solid foundation for delivering strong recurring revenues, durable free cash flow and shareholder value over the long-term. Since launching our strategy at the start of 2022, we've increased high-speed broadband subscribers by 39%, nearly doubled broadband homes passed by high-speed data services, and expanded our fiber network reach by nearly 50%.

Third, our performance validates ATN's strong market position. As we have said before, we play directly into what is unquestionably one of the world's most durable secular growth environments, the need to be connected anytime and everywhere. Our network's reliability, consistency and efficiency as improved customer satisfaction as exemplified by strong subscriber growth and low churn. Our deeply embedded relationships with local communities, customers, enterprises, governments and carriers continue to position ATN with an essential competitive advantage. And fourth, as we look to 2024 and beyond, we're committed to managing our balance sheet to maximize cash flow expansion and to realize the full benefits of our investments in the years ahead.

While we plan to continue to invest in our network expansion this year, we will move down the other side of our 3-year investment bell curve. As we dial back internally funded capital spending, we continue to leverage our upgraded network footprint and available grant funding to augment network expansions and continue to grow our subscriber base and recurring revenue. Additionally, we will continue to advance margin improvement initiatives to manage run rate operating costs. All-in-all, these actions position ATN to reap the full benefits of our network investment in the years ahead, including accelerated cash flow generation and subscriber and revenue growth at higher incremental margins. Let's turn to operational wins. Providing high-speed connectivity to more customers and as many remote and underserved reasons as possible is core to our mission and strategy.

In Q4, we continue to make great progress on this front in both the U.S. and international markets. We exited 2023 with 20% more high-speed broadband subscribers and 33% more broadband home passed by high-speed data services compared to the prior year. We also have had great success scaling our fiber footprint. Fiber has many advantages. It's more energy efficient, requires less maintenance and provide superior customer experience. As we replace and decommission legacy copper networks with fiber networks, we are positioning ATN to deliver higher margin revenue over time. We exited 2023 with 11,650 fiber route miles, an 11% year-over-year increase, and increased our fiber homes passed footprint by 32%. Now taking a closer look at operational highlights by segment.

Starting with our International segment, which represents about half of ATN's revenue and includes operations in Bermuda and Caribbean, where we operate in fast-growing markets like Cayman Islands and Guyana. Across this segment, we continue to see rapid uptake of high-speed broadband, with high-speed data subscriber growth of 20% year-over-year. Additionally, we have seen strong mobile subscriber growth, which grew 8% in 2023 behind investments in network core upgrade, densification and 5G rollouts. We remain optimistic about the growth and free cash flow expansion opportunities across our international markets as we continue to benefit from networking and operating investments, attractive market tailwinds and our unique value proposition.

Our U.S. segment, which serves rural communities in the West and Southwest as well as urban and rural areas of Alaska accounts for the other half of ATN's revenue. In Q4, we achieved several key operational milestones in the U.S. as we advanced our domestic strategy to increase broadband homes passed by high-speed data and pivot away from our legacy wireless wholesale roaming business by meeting our carrier customers' evolving business needs. We expanded our middle and last mile fiber networks, advanced the capacity and reach of our next-generation fixed wireless network, enabling 7% year-over-year growth on recurring business data revenue. In the U.S., we continue to pursue grant funding to augment our fiber and fixed wireless high-speed network expansion in rural areas, including parts of Alaska, Arizona, Nevada and New Mexico.

In Q4, we were recipients of nearly $4 million in Federal brands, bringing total awarded grants to us and our partners to $91.2 million in 2023. Also in Q4, we renewed our agreement with the Alternative Connect America Model Program, or ACAM, locking in the continuation of the subsidy funding to serve locations into Mexico in the amount of $118 million over the next 15 years. As it relates to grants and external funding, I want to clarify a few key points. First, one of our core competencies at ATN is our deep understanding of the mechanics of grants and third-party funding. We have a long track record of using discretion to ensure that grants we participate in are economically viable. Second, the network builds funded by these and future grants are expected to extend over the next several years.

As a result, these funds will support our continued network expansion and customer revenue growth even as the pace of our self-funded capital decreases as planned. And third, ATN is well positioned to compete for the $4.2 billion of B [ph] telecom infrastructure funding allocated to the six states that we operate in. We are actively working in jurisdictions on the opportunities that align with our business strategy. In conclusion, our strategy to expand high-speed network reach capabilities, while managing costs through margin improvement initiatives, positions ATN to reap the benefits of our investment for years to come. Looking ahead to 2024, it's all about continued execution of our plan. Our priorities remain to continue growing high-speed data network subscriber base and expanding our fiber footprint through targeted internal funded investments, albeit at a slower pace as we come down the backside of our 3-year investment bell curve, to pursue economically viable grants to augment these internal investments, to advance margin improvement initiatives, and to manage our balance sheet to maximize cash flow and increase shareholder value.

And with that, I'll hand the call back to you, Justin.

Justin Benincasa: Great. Thank you, Brad. ATN's strong fourth quarter and full year performance reflects our team's hard work executing against our 3-year strategic investment plan. In 2023, we achieved consistent top line growth and even stronger adjusted EBITDA growth, well in line with our guidance for the year. Turning to the P&L highlights. In Q4, total company revenue of $199 million grew 4% before construction revenue compared with the same period in 2022. Higher fixed revenue was driven by growth in rural broadband revenue and high-speed data subscribers. The quarter also benefited from $3.1 million of non-recurring revenue associated with engineering services we provided on a fiber deployment. For the full year, revenue totaled $762.2 million.

This represents a 6% increase over the prior year, excluding construction revenue from both periods, reflecting the momentum of our strategic network investments. Operating income in the fourth quarter was $3.3 million versus $4.7 million in Q4 of 2022. The year-over-year decrease was due to a $6.6 million restructuring charge related to our ongoing efforts to better align our cost structure to the future needs of the business, and a $1.3 million net loss on the disposition of assets and changes in contingent considerations. Full year operating income for 2023 increased to $13.2 million, which was negatively impacted by restructuring charges of $11.2 million. This compares to operating income of $7.9 million in the prior year. Adjusted EBITDA growth was exceptionally strong for both the fourth quarter and the full year, increasing 13% to $51 million for the quarter, and 10% to $189.5 million for the full year.

This performance was fueled by strength across both segments as we benefited from higher revenue and our ongoing margin expansion initiatives. Net loss in Q4 was $5.8 million, or a loss of $0.46 per share, compared with prior year's net loss of $1.4 million, or a loss of $0.18 per share. The quarter was affected by the restructuring charge and a year-over-year increase in interest expense of $4.7 million. For the full year, the net loss was $14.5 million, or $1.25 per share, which included the restructuring charge of $11.2 million and higher interest expense year-over-year. This compares to a full year 2022 net loss of $5.6 million or $0.67 per share. Looking now at the segment performance. The International segment delivered revenue growth of 5% in the quarter and 4% for the full year.

As Brad mentioned, we saw strong high-speed data subscriber growth that drove increased fixed broadband revenues. Mobile revenues in the segment were flat in the quarter as strong subscriber growth for the segment was offset by a lower ARPU in some of our bigger prepaid markets. Adjusted EBITDA for the International segment increased 6% for the quarter and 4% for the full year. In our Domestic segment, total Q4 revenue grew 3%, driven by the growth in fixed revenue and engineering services, as I previously noted. On a full year basis, Domestic revenue increased by 6% as we benefited from strong fixed revenue growth related to greater enterprise and emergency connectivity fund revenue in Alaska as well as the Sacred Wind acquisition. Carrier revenues were flat, both for the quarter and the year.

As Brad mentioned, moving into 2024, we will have transitioned the bulk of the carrier service revenue from the legacy wholesale roaming revenue to offering a suite of infrastructure and network services to our large carrier customers in the U.S. Adjusted EBITDA for the Domestic segment was very strong, up 20% for the quarter, well outpacing our revenue growth, and up 17% for the year as we benefited from margin expansion efforts that we have been -- that have been in focus throughout the year. Moving on to the balance sheet and cash flow highlights. We exited the year with a net debt-to-adjusted EBITDA ratio of 2.4 times on total debt outstanding of $517 million. Net cash provided by operating activities was $113 million for the year, up from $103 million in the prior year period as the funding of working capital improved in 2023.

Maintaining the strength of our balance sheet remains a top priority for ATN, and we expect to continue expanding cash flow as we leverage the benefit of our investments made in our networks over the past few years. Turning now to capital expenditures. In line with our 3-year strategic investment plan for the full year 2023, we invested nearly $200 million, expanding both the reach and quality of our networks in all our markets. Of the nearly $200 million invested, CapEx funded through operations was $163.3 million, and $32.9 million was funded through reimbursable government programs. These investments have upgraded the capabilities of our networks, and enabled our teams to greatly expand the reach of our fiber facilities that ATN can leverage for years to come.

As provided in our guidance, our CapEx spending through operations is expected to decrease substantially in 2024 and continue to move lower into 2025. We expect to augment this more normalized CapEx spending levels with government subsidy grant programs and funding. Returning capital to shareholders remains a capital allocation priority. In 2023, ATN returned $15 million to shareholders through our share repurchase program, and we paid out an additional $13.2 million in dividends. In December, we announced the Board of Directors' decision to increase the quarterly dividend 14% year-over-year to $0.24 per share, and the expansion of our share repurchase program, allowing the company to repurchase up to an additional $25 million of common shares.

Turning now to our full year 2024 outlook. For the full year, we expect total company revenues in the range of $750 million to $770 million, excluding construction revenue. As a reminder, a $27 million annual COVID-related government contract is scheduled to expire at the end of the first quarter in our U.S. segment, which will affect year-over-year revenue growth comparisons beginning in Q2. We expect other revenue growth to offset that reduction as we move through the year. We continue to expect adjusted EBITDA for the full year within our previously provided preliminary guidance range of $200 million to $208 million. As we move through 2024 and begin to expand cash flow, we expect to exit the year with a net debt ratio of between 2.25 to 2.4 times.

As I mentioned previously, maintaining healthy debt levels is a top priority for ATN, and our goal remains to continue bringing leverage closer to 2 times over the medium term. Turning now to our capital expenditure guidance. After reviewing our 2024 projects and the status of grant funding we are eligible for, we have lowered our capital expenditure outlook by $10 million to a new range of $110 million to $120 million. As a result of the investments we've made, ATN is in an excellent position to expand cash flow and fuel profitable growth in the years to come. Finally, as announced at the end of last year, this will be my last earnings call as CFO before I retire. Reflecting on my past 18 years with ATN, I'm proud of the organization that we've built and the incredible progress this entire company has made together over the years.

I truly value my partnership with Michael over the past 18 years and the great team of financial executives and our assistant, Kathy, who supported us both for much of that time. I'd also like to express my gratitude to the opportunity to connect with many of you, our shareholders and analysts that cover ATN. I truly appreciate the support you provided me over the years. Having worked closely with Brad for several years, I have the utmost confidence that he is the right leader for ATN at this stage in our transformation. Additionally, in my time with Carlos, I can assure you he is a seasonal leader, with strong industry knowledge, financial and operational experience and a collaborative approach to business. I have the full confidence that Brad and Carlos will seamlessly lead ATN through the completion of a 3-year strategy and set a compelling vision for ATN's next phase of growth.

Before opening up to questions, I'd like to just turn the call over to Carlos, who has a few words to say.

Carlos Dalioli: Thanks, Justin. Hello, everyone. It is an honor to be here today. ATN is a solid company that has been investing in the foundation for the continuing creation of shareholder value. Since joining ATN in January, I've been impressed with the thoroughness of ATN's finance team, the strength and experience of the leadership team and the clarity of the organization's mission and strategy. I am grateful for the quality time that I have spent with Justin. I look forward to building on the disciplined financial foundation he has established to continue to generate value for our investors and stakeholders for years to come. I look forward to meeting with many of you in the months ahead. And with that, I turn the call back over to Brad.

Brad Martin: Thanks, Justin and Carlos. We are very excited for ATN's future. Through our First-to-Fiber and Glass and Steel investment strategies, and ongoing focus on margin improvement, we are laying the foundation for durable long-term growth in the years ahead. The ATN value proposition continues to resonate with customers around the globe. Our teams remain energized, execute on our promise to help rural and underbuilds communities advance their quality of life through reliable, high-quality digital connectivity. With that, operator, we'd like to open up for questions.
