Thank you, Elissa. Good morning, everyone, and thank you for all of you for participating in Packaging Corporation of America's Third Quarter 2025 Earnings Release Conference Call. Again, I'm Mark Kowlzan, Chairman and CEO of PCA. And with me on the call today is Thomas Hassfurther, President; and Kent Pflederer, our Chief Financial Officer. I'll begin the call, as usual, with an overview of our third quarter results, and then I'll turn the call over to Tom and Kent, who will provide further details. And then after that, I'll wrap things up, and we'd be glad to take any questions. Yesterday, we reported third quarter net income of $227 million or $2.51 per share. Excluding the special items, third quarter 2025 net income was $247 million or $2.73 per share compared to the third quarter of 2024 net income of $239 million or $2.65 per share. Third quarter net sales were $2.3 billion in 2025 and $2.2 billion in 2024. Total company EBITDA for the third quarter, excluding special items, was $503 million in 2025 and $461 million in 2024. The third quarter net income included special items expense of $0.22 per share. The $0.22 were costs related to the acquisition of the Greif Containerboard business, including step-up of the acquired inventory, integration-related expenses and transaction expenses. Details of the special items for both the third quarter of 2025 and 2024 were included in the schedules that accompanied our earnings press release. We completed the acquisition of the Greif Containerboard business on September 2. Our results included 1 month of the acquired operations from Greif, which impacted earnings per share by $0.11 after special items. These include depreciation and amortization after preliminary purchase accounting and additional interest on new borrowing to finance the acquisition. Excluding the special items and the impact of the acquisition, our earnings increased by $0.19 per share compared to the third quarter of 2024. This increase was driven primarily by higher prices and mix in the Packaging segment for $0.73, lower fiber costs of $0.16, higher prices and mix in the Paper segment, $0.02 and a lower maintenance outage expense of $0.01. Partially offsetting the improvements were higher operating costs, $0.33; lower production and sales volume in the Packaging segment, $0.16; higher depreciation expense, $0.07; higher freight expense, $0.07; higher fixed and other expenses of $0.07 and higher interest expense, excluding the Greif acquisition debt of $0.02 and lower production volume in the Paper segment for $0.01. Because of the uncertainties of the Greif closing date, our third quarter guidance did not forecast any impact from the acquisition. Excluding special items and acquisition impact, the results were $0.04 above the third quarter guidance of $2.80 per share, primarily due to favorable price and mix in the Packaging segment and lower freight costs. Looking at our Packaging business and including the acquired business, EBITDA, excluding special items in the third quarter of 2025 of $492 million with sales of $2.1 billion resulted in a margin of 23.1% versus last year's EBITDA of $446 million and sales of $2 billion or a 22.2% margin. Corrugated volume was largely on plan and continued to reflect the cautious ordering patterns we've seen most of the year. We ran to demand during the quarter and produced 38,000 fewer tons of containerboard than the third quarter of 2024 and 59,000 more tons of containerboard than the second quarter of 2025. Our containerboard inventory in the legacy system increased by 15,000 tons during the quarter in preparation for the fourth quarter DeRidder outage. From the operational standpoint, we ran very well the entire quarter and with strong performance in terms of cost and production efficiency across the entire mill and corrugated system, which is a testament once again to the successful investments across our business. We continue to look every day at opportunities to take out cost and optimize production capabilities with the support of our considerable in-house technical and capital execution expertise. The acquired mills produced 47,000 tons during the month. Having closed the acquisition on September 2, we used the initial month of ownership to our advantage. While our activities impacted the September results, they will improve long-term productivity and efficiency. Massillon had a scheduled annual outage -- maintenance outage, which we extended to 5 weeks and completed earlier in October. We did a comprehensive refurbishment of the mill, including reliability improvements on the paper machines, the OCC plant and the power plant. All mill infrastructure and unit operations were cleaned and inspected. We took the 2 paper machines at the larger Riverville facility down for 5 days a piece to implement the first phase of our reliability improvements. We'll have additional work to do to implement our efforts and expect to have achieved the first phase by the end of the fourth quarter. We're already seeing the benefits of improved performance and quality with both mills running at higher performance. We'll continue to manage and invest in these facilities to achieve operating performance in line with the legacy PCA system. I'll now turn it over to Tom, who'll provide more details on the containerboard sales and corrugated business.
