Thank you, Melanie. Good morning, everyone, and thank you for joining us on the call today. Graphic Packaging is off to a great start 2023. We continue to advance our proven strategy centered around running a different race as we build our leadership in fiber-based consumer packaging. Our strategy is focused on driving growth by executing differentiated strategic capital investments and enhancing long-term partnerships with customers, while expanding consumer packaging expertise and innovation capabilities. During the first quarter, strong execution by our global team enabled us to deliver on the strategy, create value for customers and shareholders while positioning the business for the future. Let's start with this quarters key highlights on slide three. Amid a challenging macroeconomic backdrop, we drove continued net organic sales growth and margin expansion during the first quarter. This performance is a testament to the resiliency of our business model, as well as the strong and growing consumer demand for renewable recyclable fiber-based packaging. As part of our differentiated strategy, we continue investing to capitalize on this clear consumer preference by building new capabilities and driving innovation. As we will discuss in further detail, our recycled paperboard investment in Kalamazoo is exceeding expectations and we are making progress to build upon our distinctive competitive advantage with new mill in Waco, Texas. Importantly, we're not the only ones investing in response to the consumer preference for more sustainable packaging. Leading brands and manufacturers recognize this consumer trend and the solution, our new capabilities and innovations can provide. We are pleased to announce today that Chick-fil-A, is going to mark better this month with our new highly insulated double wall fiber-based cups as a potential long-term solution for their beverage program. This is the latest example of the significant opportunity for us within the food service space. Given our strong start to the year and confidence in the path ahead, we are raising our full year EBITDA guidance by $100 million to $1.9 billion at the midpoint of the range and updating other guidance metrics as a result. In 2019, we established our original Vision 2025 goals. With the increase outlook for 2023 we are providing today we are on-track to achieve those original targets two years early and have a clear path to meet the enhanced Vision 2025 financial goals we announced in February of 2022 at our Investor Day in New York. Slide four captures our key financial metrics for the first quarter. Sales increased 9% over $2.4 billion driven primarily by positive pricing and organic sales growth. Adjusted EBITDA of $484 million grew at a faster pace and sales as our margin expanded by 430 basis points to 20%. This represents a new high for adjusted EBITDA margin and provides further confidence in achieving our Vision 2025 financial goals. Taken together our strong sales and EBITDA performance lead to adjusted earnings per share of $0.77, an increase of 60% versus the prior year quarter. As we deliver on our near term financial goals, we are continuing to invest in new capabilities to build on the strong performance in the future. Most notably, we are making considerable progress on our CRB platform optimization, which is detailed on slide five. Our new K2 machine in Kalamazoo results in Graphic Packaging operating the world's lowest production cost, highest quality coated recycled paperboard mill. The largest capital investment we've made to date K2 came to life in early 2022 as we successfully ramped production on the machine. Now that we are fully ramped, the capability of K2 is exceeding our expectations in several ways. First is quality. We are now capable of producing a new innovative higher quality CRB grade that meaningfully expands opportunities for the substrate and our network overall. I will elaborate more on this exciting development in a moment. Second is yield. We now expect K2 to deliver 550,000 tons of annual production compared to the 500,000 tons we previously announced. And finally, financial benefits. We had previously announced the investment would drive approximately $130 million of incremental annual EBITDA improvement over three years. I'm pleased to report that we now expect to reach that target in only two years of full year ahead of schedule. The outstanding execution of the K2 ramp is a testament to the great work and dedication of our Kalamazoo team. Additionally, the success of the investment provides us with the expertise and confidence to continue to strategically invest to redefine the fiber-based consumer packaging landscape, as we are doing in Waco. We announced the Waco investment less than three months ago and we have already made meaningful progress excavating the site, ordering equipment, completing the foundation and recruiting key employees. We remain on-track to meet our previously communicated timeline, including the startup of the machine in the first quarter of 2026. Taken together, these investments helped us meet the increased demand for CRB at an unmatched cost compared to our competitors. The investments in Kalamazoo, in Waco will allow us to optimize our network further by closing higher cost mills, while still expanding capacity strategically over time. Due to the better than expected production from K2, we have decided to close our CRB mill in Tama, Iowa during the second quarter, earlier than we had previously anticipated. Among our recycled paperboard mills, Tama has the smallest capacity and the highest cash production costs per ton. As closure advances our strategy to simplify our paperboard network well strategically expanding capacity and lowering cost. Factoring in both Waco and plan mill closures, our optimized mill network will net proximately 5% more capacity than we currently have today with flexibility to adjust capacity in line with demand. As I mentioned a moment ago, our CRB investments don't simply deliver cost and production advantages, they enable us to make an entirely new grade the highest quality coated recycled paperboard available. By utilizing K2 state-of-the-art technology, we can produce the new grade of recycled paperboard with enhanced appearance and performance characteristics as well as superior economics. The improved quality expands the breadth of our opportunities for CRB-based packaging to new consumer end markets that have historically only been served by virgin substrates, such as FBB or SBS or other materials. Slide six illustrates a few examples of where we expect CRB to play over time. In short we expect to see CRB and more products and consumer experiences. We're in the early innings and are currently conducting trials of our higher quality CRB grades. We look forward to sharing more on these opportunities in the coming year as part of our ongoing innovation story. The adoption of CRB for certain packaging applications historically require a virgin fiber will enable continued substrate optimization across our mill network. This is important as it frees up virgin capacity in our other mills to capture growing global demand without the need for additional capital investments. Our CRB investments in paperboard great innovation are clear examples of what I mean by running a different race. We are creating opportunities for ourselves and for our customers to deploy fiber-based consumer packaging options in places where that simply hasn't been possible in the past. This is a key factor in driving not only the depth of our customer relationships, but also our growth and performance. Slide seven is a great example of innovation at our virgin substrates and the enormous opportunity to replace packaging created from non-renewable resources not as widely recycled as fiber-based packaging. Illustrated on this slide is our proprietary highly insulated double-wall fiber-based cup solution developed as an outstanding alternative to the foam cup. Our new cup boasts a number of features that set it apart from others available at quick-service restaurants providing consumers a dual cup solution that sweats less, is more durable and has enhanced insulation properties, delivering added appeal to consumers are the improved sustainability features. The result is a better beverage experience for the consumer. Chick-fil-A, is the largest quick-service chicken restaurant chain in the United States and an existing Graphic Packaging customer. Today, we are announcing an expansion of that relationship with the launch of our proprietary cup innovation in Chick-fil-A, locations from California to Maryland. Stage one of that launch is focused on approximately 10% of the customer's restaurant footprint. Over time, our innovation can be a potential long-term solution for Chick-fil-A beverage program, including the ability to work in both cold and hot beverages. Driving innovation with industry leaders like Chick-fil-A is a great example how leading brands are investing to transition toward more sustainable packaging solutions and how we are partnering with them to effectively manage that transition. While progress has been made to transition away from foam and plastic, Americans still use roughly 45 billion of these cups each year. Consumers are calling for change and environment less ways. Our customers are looking for us to help. We believe our new insulated cup innovation has tremendous potential to win and what we estimate is a $2 billion addressable foam and plastic cup market in the U.S. To put that in different terms, our $2 billion addressable market opportunity equates to roughly 600,000 tons of SBS paperboard demand. We are uniquely positioned to service this demand by leveraging our integrated platform as our customers meet to call from consumers. Our CRB mill project underway in Waco, with its enhanced cleaning of separation system will provide increased cup recycling capabilities. We look forward to partnering with QSR customers like Chick-fil-A and enhanced cup recycling programs and support on move to a more circular economy. And with that, I'll turn the call over to Steve to provide more detail on the quarters financials.
