Good morning, and thank you for joining our call. I'm going to start with some high-level thoughts on my first year as CEO, and I'll provide some comments about our 2023 performance. I'll finish by reiterating my confidence in our ability to take advantage of strong market opportunities in 2024 and beyond. As then as usual, I'll hand it over to Scott, and he'll discuss financial results in more detail and our outlook for 2024 and we'll open the line for questions after that. As you probably know, I've been the CEO first on an interim basis, and then since June of last year, on a longer-term basis. And during that time, I've made it a point to personally visit as many customers, partners and fellow ACI team members as possible. In that year, I've met in person more than 70% of our employees and all of our top 10 customers in more than 15 countries across five continents. And following those visits, I'm even more convinced that ACI is a company with world-class solutions, talented employees and a customer base unmatched in the industry. Our market position, combined with the substantial opportunities for expansion and growth in industry with a near continual change puts us in a position to accelerate our growth and help customers achieve and exceed their strategic objectives. More on the future in a moment. I'm going to start with 2023. We had a solid performance. We exited the year strong, and that has set us up to accelerate our growth this year. We delivered results in line with or above our expectations and with the guidance we provided to you this time last year. We saw strength in our Biller segment with revenue growth of 9% and EBITDA growth of 32% in 2023. We went live with the first two of several phases of the implementation of a large new Biller customer that we signed in 2022. More phases of that program go live in 2024, and they're on track. We also signed a large new utility customer that is on track to go live and begin ramping in the middle of 2024, and we continue to make incremental progress with our interchange improvement program. Our banking segment saw a notable strength in cross-sales of our anti-fraud and real-time payment solutions, and those saw a revenue growth of 35% and 24%, respectively, in 2023. Our anti-fraud solution utilizes artificial intelligence and proprietary access to ACI generated big data to truly lead in the category. So we continue to be excited about our opportunities in real-time payments. To illustrate our continued success in this area around the world, we signed up three new central infrastructures in the quarter including, El Banco de la Republica de Colombia, and the Nepal Clearing House. We're now supporting nine central infrastructures globally along with more than 25 national and regional real-time payment schemes. And lastly, in our Merchant segment, though we had a bit of a slow start to 2023, we exited the year with a strong Q4 rate of growth, and we expect growth to accelerate in 2024. We remain excited about leveraging our best-in-class payments expertise to help our clients offer the optimal payment choices to their consumers while providing a safe, secure payment processing environment. Our proprietary AI-driven fraud management tools are helping to protect our billers and merchants from fraudulent transactions. Perhaps most importantly, our sales pipeline is strong and growing. And we expect to see particularly strong demand in our banking segment. As I mentioned on our last call, the maturation of real-time payments around the world is driving an intense analysis of payments technology infrastructures by banks everywhere. When these institutions think about which firms to work with, to address this critical need, ACI is virtually always on the list and near the top. Because of our history, market presence and proven expertise, we are a usual suspect. The fact that many of the largest financial institutions in the world already rely on our proven software means we're the only choice for a lower risk, high reliability modernization. ACI's reliability and scalability are unquestioned, and we are seeing significant demand for our solutions, including our payments hub across the globe. Speaking of our payments hub, we're engineering it to support on-premise cloud and SaaS delivery models making us a great choice for large and mid-tier financial institutions alike. Mid-tier or super regional sized customers in the past that often did not have the established infrastructure to take advantage of ACI's highly reliable and scalable software, our newer solutions, cloud enablement and SaaS offerings have made this possible. You'll hear more about this at Analyst Day, but I want to reiterate, this is a net new opportunity for us. It substantially increases the size of our historic addressable market. And it presents an opportunity to bolster our already accelerating growth rate. Our Biller segment, which saw a significant turnaround in 2023, will see further growth in 2024 and as we get a full year benefit of customer go-lives we saw in 2023 as well as the go-lives of additional large customers sold during last year. This revenue growth, combined with continued success in our interchange improvement program, will continue to deliver margin improvement. In our Merchant segment, our investments are paying off. We saw Q4 deliver the strongest rate of quarterly growth of the year, and we expect that momentum to carry into 2024. In fact, we signed a significant new customer in the fuel store segment in the first week of the year, a great way to start. Overall, I'm pleased with where we are as a company. We have a strong balance sheet, we have leverage below our long-term target, and we're accelerating our top line as we've long promised. We're managing our expenses well. We have a strong team. We have a strategy in place that positions us well to accelerate growth in 2024 and beyond. I'm also happy to announce that today, we've appointed two new members to our already strong Board of Directors. Katrinka McCallum, who spent many years at SaaS software company, Red Hat, most recently as Vice President of Customer and Product Experience, and Juan Benitez, the former President of GoFundMe and General Manager of Braintree, which is now part of PayPal. Katrinka and Juan will provide great support as we expand our SaaS businesses and drive accelerated productivity through more use of Generative AI, large learning models and machine learning, things both of them have overseen before. Before I turn it over to Scott, I want to remind you of our upcoming Analyst Day. As John mentioned, we're hosting an event in New York City on March 12. We invite you to attend in person or online as we discuss our business segments and exciting global opportunities. With that, I'm going to turn it over to Scott to discuss financials and guidance. Scott?
