Thank you, Mark. Good morning, everyone, and thank you for joining our call today. Graphic Packaging is a global leader in sustainable consumer packaging. In the first quarter, our business faced considerable pressure, has already stretched consumers pulled back further, promotional activity by our customers did not drive meaningful volume improvement, and we experienced significant input cost inflation. While these challenges won't be resolved overnight, neither are they long-term in nature. We have taken actions to offset higher costs and continue to generate innovation sales growth that is helping us grow faster than the end markets we serve. Despite near-term challenges, we remain well-positioned to generate substantial cash flow in the quarters and years ahead. In the first quarter, Graphic Packaging sales were $2.1 billion, adjusted EBITDA was $365 million, and margins were 17.2%, and adjusted EPS was $0.51. Those results were significantly below our expectations, driven mainly by weaker volumes in the Americas business and broad-based input cost inflation. Turning to slide 3, our Waco recycled paperboard investment is on track for startup. Hiring is effectively complete, and I have been extremely pleased with the quality of the team we've been able to assemble. Training is well underway, and as you may remember, the Waco machine is nearly identical to our K2 machine in Kalamazoo, so we have experienced operators training our new team members on essentially the same equipment they will be running a few months from now. After ensuring an appropriate level of paperboard inventory for the transition, we announced that our Middletown, Ohio recycled paperboard manufacturing facility will close on June 1st. Middletown was built in 1909 and has served our company well. We announced our intention to close Middletown some time ago so the transition was not a surprise to the affected employees. We are working with the team there to provide outplacement assistance and other services. I want to personally thank the Middletown team for their dedication and commitment to excellence. With a period of major investment and competitive advantage coming to a close, we expect to generate substantial excess cash over the next several years. Yesterday, our board approved a new $1.5 billion share repurchase authorization. As we transition from our Vision 2025 to Vision 2030, our capital allocation priorities shift primarily to reinvestment and to returning capital to stock and debt holders. This new repurchase authorization reflects the board's commitment to our Vision 2030 priorities and their confidence in the strength of Graphic Packaging's team and business model. Volumes across consumer staples remain uneven and below our expectations. A stretched consumer has seen no significant relief from price inflation and consumer confidence has declined significantly in the U.S. and in the other markets we serve. Our volumes in the Americas, which were down about 1%, were disappointing, yet still broadly outperformed the CPG and QSR markets we serve. In our international business, where volumes turned positive in the second quarter of 2024, we continue to see growth, but we also see signs that consumers in international markets are beginning to pull back in their response to higher prices and greater economic uncertainty. The combination of slightly positive overall volumes and modest price pressure left our reported revenue essentially flat, excluding the effect of May 1, 2024 Augusta divestiture. The modest price pressure mostly reflects the impact of third-party price recognition made in the middle of 2024 and some mixed shifts. On April 15, we announced a $40 price increase on all of our recycled and unbleached paperboard grades effective May 15. We have a very good record of offsetting labor benefit and other costs through efficiency and net performance gains, and we did that again in the quarter. But when we experience meaningful input cost inflation, like we did in the first quarter, we will pass those costs through to our customers. Turning to the five major markets we serve; food and health and beauty saw some modest improvement versus last quarter. Foodservice and household products were relatively flat, and beverage was down against a strong comparison last year, despite higher promotional activity and soft drinks. With food prices still high, we have seen the consumer search for value expand. Shoppers across most income brackets are now making different choices in response to relatively high food and household product prices, and that appears to be particularly benefiting our mass retail, superstore, and discount grocer customers. I am sure you've read the same reports that we have of consumers shopping in more stores buying fewer items in each one as they seek out the best value. Where consumers shop doesn't have a big impact on us, but our customers are seeing real volume declines in total goods purchased, and that certainly does affect us directly. We continue to broadly outperform North American CPG and QSR markets, largely as a result of our innovation sales growth, which came in at $44 million for the quarter. That growth came across a wide range of product categories, with several new contributions in strength packaging, coffee, snacks, and cleaning products. Meanwhile, our paperboard canister continues to expand into new products and new markets, and we see a good tailwind in Europe in beverage multi-pack demand, thanks to regulatory requirements that are phasing in over the next few years. I am often asked if consumers are pulling away from innovation and sustainability initiatives to save money in this uncertain environment. In the first quarter, we did see a few customers slow down their roll-ups, but most launches remained on schedule. We tend to have about six to nine months of visibility in terms of new product development, and I feel very good about reaching our innovation sales growth target of at least 2% in 2025. Turning to slide 4, the breadth and depth of our consumer staples packaging portfolio is the foundation of our strength. We are in every aisle of the supermarket, our major packaging supplier to the quick service restaurants, and expect to grow our presence substantially over time across household products and health and beauty. We can't change the macroenvironment, but our ability to move with the consumer is a key source of top line consistency over time. Turning to slide 5, let's look at sales by market. Overall, first quarter sales were basically flat year-over-year. Food represents approximately 38% of our packaging sales, and we saw some overall improvement, but results by product category remained very uneven. Promotional activity was not materially different from the fourth quarter, and appears to have again driven more brand and mix change than overall category volume growth. Cereal volumes improved modestly with gains by branded products, more than offsetting weaker private label results, mostly as a result of promotional activity. Dry pasta and dry prepared foods like mac and cheese showed incremental strength, while some frozen prepared food categories lost ground. Frozen complete meals, for example, continue to lag as consumers balance cost against convenience. Bars, as a snack and meal replacement, continue to gain, supported by trends including higher protein diets, GLP-1, returning to the office, convenience and portion control. Coffee and tea again showed solid gains, thanks in part to our already own product innovation, but also from a shift in coffee consumption to the home and office and away from coffee shops. Tariffs could have a material impact on European coffee producers, given the higher proportion of European coffee that is exported to the U.S. Beverage, which represents about 25% of our overall packaging sales, saw its first decline after two years of strong performance. While beer consumption trends continue to slow, we did see some positive impact from promotion and soft drinks in the quarter, as well as gains by alternative beverage, including energy and nutritional drinks. And in that alternative category, we saw notable gains by private label producers, continuing on the trend that we have seen in soft drinks. Foodservice represents 21% of our packaging sales. Year-over-year results were relatively unchanged, with basically flat performance in the Americas and a pickup in our smaller international business. While we saw higher promotional activity by quick service restaurants, traffic remained relatively flat, even as a shift towards value menus and limited time offerings became more pronounced. We saw growth in foodservice demand from supermarkets and U.S. convenience stores, where investments in freshly prepared foods and bakery items have shown some success, taking volume from the QSR channel. Muscle products represent approximately 12% of our packaging sales and saw uneven results, with modest weakness in the Americas, offset by pockets of significant improvement internationally. Laundry detergent pods, where our child-resistant paperboard solution is replacing plastic and plastic film from major European brands, continues to be solid growth opportunity for us. Pet food remains strong, while tissues weakness continued. And finally, health and beauty, a small but promising part of our overall packaging sales, saw mixed results in international, but better results in the Americas. In international, we saw incremental weakness in everyday skin care and other wellness products as consumers tightened their belts, but we saw a modest gain in the Americas. Health care was about flat in both markets. If you'll turn with me to slide 6, we present typical seasonal patterns on the left and our actual and expected experience on the right. While normal quarterly seasonality was evident in most categories, food was modestly weaker than normal. As we noted in our February earnings call, January started out slow in large part to unusually cold weather that led to fewer trips to the grocery store. As the quarter progressed, our customers continued to see relatively weak volumes without the normal February dip and the March rebound. And as you've read elsewhere, the search for value is not just focused on lower income brackets. Consumers across the income spectrum and increasingly across our international business are searching for better value and many are cutting back for the can. Meanwhile, as I noted earlier, promotional activity by our CPG and QSR customers has not translated into meaningful volume improvement or higher foot traffic. Private label and mass retail continues to gain in that environment. Cost inflation, which looked relatively benign early in the quarter, picked up considerably across most our inputs other than fiber. As we look to the second quarter, input cost inflation remains significant and at the consumer level some categories, particularly the food, are experiencing renewed retail level price increases. When we spoke last quarter, we said we weren't banking on a consumer recovery. As we look to the 2025 outlook, a 2% volume decline is now our base case. That is a very challenging backdrop for our CPG and QSR customers and we continue to work with them to deliver the best packaging solutions for their strategies. Another trend I'm often asked about is private label and if growing private label has implications for innovation growth and for our margins. The reality is that private label has been a significant part of our innovation sales growth and particularly with some of our highest value innovations like Oreo and Paper Seal. Retailers want their own brands to stand out on the shelf and are just as committed to plaster production as most CPGs. Our experience has been that our margin with private label customers is not materially different from our branded customer margins. Slide 7 seven highlights our five packaging innovation platforms and notes the scale of the opportunity we see in each one. My confidence in the size and scope of the opportunity in each of these areas continues to rise. Each new commercial success, Paper Seal for prepared food for example, not only adds to our sales but also adds to our insights and our confidence and our ability to expand in new markets and we are doing just that. Turning to slide 8, EnviroClip Beam is our proprietary solution for PET bottle multipacks. Developed in the United States, it is now rolling out with our first customer in the UK, a rapidly growing independent beverage producer. EnviroClip Beam is an outstanding low-impact alternative to plastic ring carriers and shrink wrap that offer exceptional product stability, superior marketing value and is plastic and glue-free making it fully recyclable. Turning to slide 9, our vision for Graphic Packaging is clear. After a half decade of transformational investment capabilities, innovation and competitive advantage, our focus turns to innovation and execution. We have built our company culture around safety, engagement and delivering for our customers. Our commitment to improving the environmental footprint of consumer packaging is at the center of our mission. Pulling those three things together, innovation, culture and commitment to sustainability is how we generate best-in-class results for customers and for all our stakeholders. Now let me turn it over to Steve for a review of the company's financials and operations. Steve?
