Thank you, George. Welcome, everyone, and thank you for joining our fourth quarter 2024 earnings call. We executed a strong quarter to finish 2024, delivering on our financial targets and setting up continued attractive earnings growth in 2025. Our goal every year is to deliver earnings growth well ahead of revenue growth driven by technology-enabled productivity gains and a scalable cost base, all while generating strong free cash flow investing in our future growth. And that's exactly what we did in 2024. This was a record year for adjusted EBITDA and revenue for the company. Adjusted EBITDA exceeded the midpoint of our original guidance range, up 26% year over year. 2024 highlights our powerful financial model with impressive growth on the bottom line as we drove adoption of our software solution and automated our processes. Adjusted EBITDA margin expansion was over 300 basis points, reaching 20%. Investments in our software and services are delivering top-line growth. As we continue to win new customers and importantly maintain very high customer retention. 2024 was a record year GMN customer retention at an impressive 99%. We also reached important milestones, strengthening our balance sheet, accelerating free cash flow, investing in growth, and returning cash to shareholders. We more than tripled free cash flow in 2024, ending well above our original guidance for the year. We have lowered our leverage ratio below two times and we continue to lower our interest costs with a repricing completed after the fourth quarter closed. Our increasing flexibility with capital allocation allowed us to make our first share repurchase in a private transaction in the third quarter followed by a $300 million buyback authorization. I'm pleased to say we are starting off 2025 with good momentum to achieve another year of double-digit earnings growth. And our strategy and investments provide us with a long runway to continue this level of attractive growth. And I really want to take a moment here to thank all of our colleagues across Amex GPT for their exceptional commitment to serving our customers and the strong results that they have delivered. In 2024, we continued to execute on our strategy and deliver outstanding financial results. The momentum is evident in our financial metrics. Starting with transaction growth, full-year 2024 transaction volumes were up 5%, driven by increased demand for business travel and share gains. TGB increased 8% driven by transaction growth plus increases in average ticket price and hotel rates. Revenues increased 6% to reach $2.42 billion, driven by solid growth in transactions and TTB in addition to demand for our product and our professional services. Our focus on cost control and operating leverage drove strong adjusted EBITDA margin expansion with an increase of 310 basis points for the full year. This all translates into impressive adjusted EBITDA growth of 39% for the fourth quarter, ending the year, with $478 million, an increase of 26%. Drilling down into full-year transaction trends in more detail. As a reminder here, for organizational purposes, we divide our customer base into two general categories. Global multinational and small and medium enterprises. We generally use expected annual TTV to divide customers into these two categories although this measure can vary by country and by customer need. And we do not have products or services that are offered solely to one size of customer. You can see, growth was stronger this year with global multinational customers. An 8% increase compared to 2% for SME customers. SME transaction growth has been muted but stable for several quarters. Reflecting tightened spending controls driven by higher prices, and lower macroeconomic growth. This is a trend that we can clearly see with SME businesses beyond travel. Air transaction growth was 4% in 2024, including 4% for domestic, 3% for regional and international. Factoring in higher ticket prices, our total TTV growth for air was 8%. Growth in hotel transactions was 6%. This reflects our efforts to increase hotel bookings by strengthening our content and providing customers with more hotel value and choice. And finally, on a regional basis, transaction growth was up 5% in the Americas, 2% in EMEA, and 12% in APAC. Now let's turn to the commercial highlights. By offering customers more value and more choice, we continue to win new business and gain share. The total estimated value of our new wins signed during 2024 is $2.8 billion. This is down slightly versus the trailing twelve-month number that we shared last quarter. As we did see some global multinational prospects delay decisions into 2025, the majority of our new wins continue to come from SME customers. And new SME wins increased to $2.2 billion for the trailing twelve months. SME also remains our biggest growth opportunity with $950 billion of total travel spend and 70% of that currently unmanaged. 25% of our SME wins in 2024 were previously unmanaged customers. Reflecting increased demand, for the savings, service, and control a managed travel program with MHTBT. We are also off to a good start in Q1, and the overall sales pipeline remains strong. Customer retention was an impressive 97% of TTB, for 2024, and 99% for global multinational. Our commercial success is underpinned by the value of the GBT marketplace. For customers and suppliers. Delivering the most comprehensive content and the most competitive prices for customers and the most valuable distribution platform for suppliers. And we continue to enable NDC content at scale with our airline partners. We recently announced an enhanced agreement to expand the availability of ND fares with Lufthansa. We are now working with more than 20 airlines in our NDC program with NDC content available to more than 15,000 customers. And we have processed almost one million NDC tickets. Our development capacity of NDC now allows us to deploy a new airline, or a new country connection every two weeks. We continue to be recognized as a leader in software solutions and for making business travel more sustainable. Amex GPT Agency was recognized as a leader with 19 badges in the G2 2024 awards. And we recently launched emissions-based carbon pricing to enable companies to influence travel decisions, and to generate investment funds for low-carbon solutions like sustainable aviation fuel. We are embracing AI and automation. To improve the customer experience and improve productivity. In 2024, we have continued to invest in our proprietary AI architecture a secure privately hosted platform to scale AI initiatives with the appropriate data privacy and governance. We launched new generative AI use cases in finance, product engineering, and servicing, including large language model, chat functionality for Amex QBT Agencia in 18 countries. Before I hand it off to Karen, I want to comment on the status of the CWT acquisition. We have now cleared a significant milestone towards approval of the transaction with the UK's competition and markets authority having now provisionally concluded it has not identified any competition concerns with GBT's proposed acquisition of CWT. The CMA's final decision is required to be made by March the ninth. Although we are disappointed, by the US Department of Justice's decision to challenge the merger, the CMA's findings reinforce the company's belief that the DOJ's lawsuit is fundamentally flawed. And we expect to prove that in court if required. As we've previously stated, if approved, this transaction will accelerate the investment and innovation in business travel. It will create more choice and more value for customers and suppliers. And more opportunities for CWT employees. In the meantime, we remain laser-focused on executing our strategy and delivering another year of strong results in 2025. And now I'll hand it off to Karen to discuss our results in more detail.
