Thank you, Carol, and good morning, everyone. Before I begin, I would also like to recognize and remember those affected by the crash of United Parcel Service, Inc. flight 2976. I would like to thank our team at Worldport for their steadfast commitment to the community, their teammates, and our customers. Now let's move to our performance. This morning, I will cover four areas, starting with our fourth quarter results, then I will review our full year 2025 results, including cash and shareholder returns. Next, I will discuss the Amazon Glide Down and our network reconfiguration and cost-out efforts. Lastly, I will close with our financial outlook for 2026. Moving to our results, starting with our consolidated performance, in the fourth quarter, revenue was $24.5 billion, and operating profit was $2.9 billion. Consolidated operating margin was 11.8%, and diluted earnings per share were $2.38. As noted in our earnings press release and financials, in the fourth quarter, we took a $137 million after-tax charge to write off our MD-11 fleet. During the fourth quarter, we proactively grounded our fleet of MD-11 aircraft and leveraged the flexibility of our integrated network to seamlessly operate through peak season. Specifically, we repositioned some aircraft from other parts of the world to the U.S., increased the amount of volume we moved on the ground, and leased additional aircraft to meet capacity demand. With the learnings from operating during peak season, we made the decision to accelerate the retirement of our MD-11 fleet, which was completed in the fourth quarter. Over the next fifteen months, we expect to take delivery of 18 new Boeing 767 aircraft, with 15 expected to deliver this year. As new aircraft join our fleet, we will step down the leased aircraft and associated expense. We believe these actions are consistent with building a more efficient global network positioned for growth, flexibility, and profitability. Now moving to our segment performance. U.S. Domestic demonstrated strong performance in the fourth quarter, driven by the combination of revenue quality and great execution. We delivered a very efficient peak, which is a testament to the transformational effects from the additional automation and network reconfiguration we made throughout the year. Importantly, we continue to take care of our customers during their busiest time of the year and provided industry-leading service during peak for the eighth consecutive year. For the quarter, total U.S. average daily volume was down 2.4 million pieces or 10.8%. More than half of the decline is from the glide down of Amazon volume and our deliberate actions to remove lower-yielding e-commerce volume from our network. Total air average daily volume was down 11.9%, driven by the glide down of Amazon. Ground average daily volume was down 10.6% compared to 2024. Within ground, Groundsaver ADV declined 27.7%, mainly due to our revenue quality actions. Moving to customer mix, SMB average daily volume was flat to last year. However, in the fourth quarter, SMBs made up 31.2% of total U.S. volume, an increase of 340 basis points compared to last year. This is the highest fourth quarter SMB penetration in our history. B2B average daily volume finished down 5.2% in the fourth quarter compared to last year, but returns were a bright spot and increased 1.6% year over year. B2B represented 37.5% of our U.S. volume, which was a 220 basis point improvement versus 2024 and was the highest fourth quarter B2B penetration we've seen in six years. B2C average daily volume was down 13.8% compared to 2024. The product and customer mix improvement we saw in the fourth quarter demonstrate the progress we are making as we shift our U.S. mix to more premium volume with a focus on revenue quality. Moving to revenue, for the fourth quarter, U.S. Domestic generated revenue of $16.8 billion. This was a decrease of 3.2% year over year against an ADV decline of 10.8%, with strong revenue per piece growth largely offsetting the lower volume. In the fourth quarter, revenue per piece increased 8.3% year over year, which was the strongest fourth quarter revenue per piece growth rate we've seen in four years. Breaking down the components of the 8.3% revenue per piece improvement, base rates and package characteristics increased the revenue per piece growth rate by 340 basis points. Customer and product mix improvement increased the revenue per piece growth rate by 320 basis points. The remaining 170 basis point increase was from fuel. Turning to cost, in the fourth quarter, total expense in U.S. Domestic was down 3.3%. The decline in total expense was primarily driven by our efforts to remove hours and operational positions to align with volume. Cost per piece increased 8.9% year over year, primarily due to costs associated with the insourcing of Groundsaver, as well as additional costs to secure air capacity after we grounded our MD-11 fleet. Even in the face of unexpected challenges, the U.S. segment delivered $1.7 billion in operating profit, and operating margin was 10.2%, a 10 basis point improvement compared to last year. Moving to our International segment, we continue to adjust the network to support our customers through evolving trade policies and delivered strong top-line growth driven by revenue quality efforts in all regions. In the fourth quarter, total international average daily volume declined 4.7%, 3.5% compared to last year. International domestic ADV decreased, led by a decline in Europe that was partially offset by growth in Canada. On the export side, average daily volume in the fourth quarter decreased 5.8% versus last year, led by declines on U.S. destination lanes resulting from the change in the de minimis exemption. U.S. imports in total were down 24.4% year over year, led by an ADV decline from Canada and Mexico of 30.5%, and the China to U.S. lane was lower by 20.9% compared to last year. Turning to revenue, in the fourth quarter, we generated revenue of $5 billion, up 2.5% from last year, despite the decline in volume. Operating profit in the International segment was $908 million, down $154 million year over year, with more than half of the decline related to trade policy changes, which resulted in a shift away from more profitable U.S. import lanes. As a result, international operating margin in the fourth quarter was 18%. Looking at Supply Chain Solutions, in the fourth quarter, revenue was $2.7 billion, lower than last year by $388 million. Looking at the key drivers, within Air and Ocean Forwarding, demand softness resulted in lower market rates, which drove a decline in revenue year over year. Logistics revenue was down year over year, driven by a decline in mail innovation. This was partially offset by revenue growth in Healthcare Logistics. United Parcel Service, Inc. Digital, which includes Roadie and Happy Returns, grew revenue 27% compared to 2024. In the fourth quarter, Supply Chain Solutions generated operating profit of $276 million, and operating margin was 10.3%, up 100 basis points compared to last year. Now let's move to our full year 2025 results. For the full year 2025, on a consolidated basis, revenue was $88.7 billion, operating profit was $8.7 billion, and operating margin was 9.8%. We generated $8.5 billion in cash from operations and continued to follow our capital allocation priorities. We invested $3.7 billion in CapEx and spent $2 billion on acquisitions. We distributed $5.4 billion in dividends. Lastly, we completed $1 billion in share repurchases. In the segments for the full year, U.S. Domestic operating profit was $4.6 billion, and operating margin was 7.7%. The International segment generated $2.9 billion in operating profit, and operating margin was 15.8%. Supply Chain Solutions delivered operating profit of $1.1 billion, and operating margin was 10.6%. Now let me provide an update on our Amazon Glide Down, cost-out, and network reconfiguration efforts in 2025. We are pleased with the progress we've made after four quarters of a six-quarter glide down, and we remain on track to achieve our targeted volume reductions. As Carol mentioned, we delivered $3.5 billion in savings from our network reconfiguration and efficiency reimagined initiatives. The savings came from three buckets. Starting with variable costs, in line with the declines in volume, we removed 26.9 million labor hours in 2025. Looking at semi-variable costs, which reflect operational positions, we finished down 48,000 positions, including 15,000 fewer seasonal positions compared to 2024. Moving to our fixed cost bucket, we completed the closure of 195 operations, including closing 93 buildings. We saw savings from our efficiency reimagined initiatives continue to accelerate in the fourth quarter. As we've discussed, offsetting some of these savings was the incremental costs associated with insourcing Groundsaver, which we expect to moderate in 2026. This brings us to 2026 and the last two quarters of our six-quarter glide down of Amazon volume. In total, for the full year, we intend to glide down another million pieces per day of Amazon volume. Along with this reduction in volume, we will continue to reconfigure our U.S. network and take out variable, semi-variable, and fixed costs. Looking at the variable costs associated with the Amazon volume decline, in 2026, we plan to reduce total operational hours by approximately 25 million hours. In terms of semi-variable costs, we expect to reduce operational positions by up to 30,000. This will be accomplished through attrition, and we expect to offer a second voluntary separation program for full-time drivers. In the fixed cost bucket, we have identified 24 buildings for closure in the first half of the year, and we are evaluating additional buildings to be closed later in the year. Plus, we plan to further deploy automation across the network. Pulling it all together, we are targeting $3 billion in savings related to the Amazon glide down. Moving to our 2026 financial outlook, for the full year 2026, on a consolidated basis, we expect revenue to be approximately $89.7 billion. Operating margin is expected to be approximately 9.6%, and diluted earnings per share are expected to be about flat to 2025. As a reminder, 2025 EPS included a $0.30 benefit from a sale-leaseback transaction. Lastly, our guidance for 2026 does not reflect any significant changes to the current tariff landscape. Now let me add color on the segment. Looking at U.S. Domestic, we are going through significant structural changes, and 2026 marks the inflection point of our strategy. Full year 2026 revenue is expected to be approximately flat year over year. We expect ADV to be down mid-single digits year over year due to our actions with Amazon, which will be offset by a strong revenue per piece growth rate in the mid-single digits. Full year operating margin is expected to be flat to 2025. Looking at the shape of the year, revenue and our cost structure in the back half of the year will be meaningfully different than in the beginning of the year. In the first half of the year, we expect a decline in revenue compared to 2025, driven by volume decline. Looking at 2026, we expect to generate an operating margin in the mid-single digits. This is due to short-term transition expenses related to Groundsaver, the timing of removing Amazon-related costs, including the execution of a voluntary driver separation program, and additional expense associated with the aircraft leases related to the retirement of our MD-11 fleet. In the second half of the year, we expect high single-digit operating profit growth, reflecting the completion of our strategic actions. We will still be comping year-over-year declines from Amazon, but we expect enterprise and SMB revenue growth. First half cost pressures are expected to be behind us, and we will be running a more agile U.S. network. The USPS will be delivering some of our Groundsaver product, and our driver staffing will align with our new delivery volume level. Our results in the second half of the year will be more indicative of our go-forward financial algorithm, with an emphasis on both top-line growth and operating margin expansion. Moving to the International segment, we expect the dynamic environment we experienced in 2025 will continue in 2026, primarily due to the tariff and de minimis policy changes that will continue to drive changes in trade lane mix. With that in mind, we anticipate revenue growth to be in the low single digits year over year, driven by a solid increase in revenue per piece. Operating margin in the International segment is expected to be in the mid-teens. Looking at the first quarter, we expect revenue to be approximately flat with a year-over-year decline in operating profit due to changes in trade lanes and tough comps from the front-running of tariff and de minimis changes in 2025. In Supply Chain Solutions, for the full year 2026, we expect revenue to be up high single digits, which includes revenue from our Andalar acquisition. Operating margin in SES is expected to be in the low double digits. For modeling purposes, in total below the line, expect approximately $760 million in expense, which includes pension income of approximately $250 million, and we expect the tax rate for the full year to be approximately 23%. Now let's turn to our expectation for cash and the balance sheet. We expect free cash flow to be approximately $6.5 billion, including our annual pension contribution of $1.3 billion, but before we factor in the financial impact of a voluntary driver separation program. Capital expenditures are expected to be about $3 billion. We are planning to pay out around $5.4 billion in dividends in 2026, subject to Board approval. To close, I would like to echo Carol's comments and express how proud I am of our teams for executing the strategy while continuing to take care of our customers. Our efforts today are setting our business up for future margin expansion and greater operational agility. We are focused on growing in the best parts of the market to deliver long-term value for our shareholders. With that, operator, please open the lines for questions.
