Thank you, Sue. Now on to a quick review of each of the businesses. As seen on Page 24, our Performance Chemicals business finds itself in a challenging spot that it hasn't experienced in a few years, as we've seen some residential preservative volume move away from Koppers after many consecutive years of market share gains. To compound matters, after a solid start to the year, demand seemed to lose steam as the quarter progressed, partly due to a colder winter throughout the country and partly we believe the broader economic uncertainty stifling individuals' decisions to spend discretionary dollars on outdoor projects. Now nothing in the external data gets us really excited that spending on home projects will turn around soon. The continued backdrop of economic uncertainty driven by tariff activity and the direct and unintended consequences remain a concern that could continue to weigh on near-term demand, and we're hearing mixed messages from our customer base in regards to their optimism for volume improvement this year. And we've enacted several tariff mitigation actions that have reduced the overall exposure from our cross border transactions across all our business segments. As a result, at this point, we feel the situation is manageable, but as we know, it remains fluid. On the cost front, we've paired back spending quite a bit and realigned cost to better fit a smaller top-line in the near future and will continue to be aggressive in order to combat any potential market slowdown. Moving on to our Utility and Industrial Products business shown on Page 25. Demand in the early part of this year has been similar to 2024 levels, which was a softer year compared to '23. While the second quarter isn't expected to look a whole lot than the first, we continue to hear that, volume is expected to pick up in the back half of the year. Like our PC business, I do have some worries that persistently high interest rates and fiscal policy uncertainties could dampen enthusiasm in the industry to move forward with projects. That however does not change my long-term view on this business, as various demand drivers remain in place to support a bullish outlook. We're starting to see greater interest from the customer base in our new geographic markets and we continue to invest resources to build out our sales team and distribution network to support our expected growth in those underrepresented areas. As I mentioned earlier, the sites acquired from Brown Wood a little over a year ago play a key role in accessing some of these markets and they're performing solidly. On a final note, our Australian coal business had its best Q1 since 2021 and we're anticipating another year of steady profitability. Our railroad products and services, business is summarized on Page 26. While volumes in Q1 weren't quite where we expected them to be, the combination of small contractual price increases and lower operating costs led to our best profit metrics in the crosstie part of our business since 2016. Now if our sales reach the 8% improvement we plan for coming into this year, then 2025 should represent one of our strongest years ever for the rail business. Presently, we have no major capital need for this business and our inventory is at a good level, which means, it should be back to generating significant free cash flow. We've been able to avoid tariff impact for this business thus far, but we do worry about the tariff effect on some of our sawmill suppliers who rely heavily on hardwood exports to China, which have dried up. Our shift away from the disposal part of our crosstie recovery model was already generating positive benefits and we expect greater consistency in our financial performance from that piece of RPS as a result. Overall, our maintenance -- weight business was a solid contributor to the RPS results in Q1 and as of now are on pace for their best year since 2016. Next on to the CMC business which is summarized on Page 27. Like last year's fourth quarter, the first quarter for CMC represented significant improvement over the prior year performance. That improvement came despite a lower sales figure with some due to the ramp down of our phthalic anhydride production and the other half due to lower product pricing. As in all our businesses, we remain focused on driving down costs to support better operating performance. Our exit of the phthalic anhydride business in the U.S. supports that concept through reducing the complexity of our operations, which will improve our cost structure as well as the safety and environmental footprint of our Stickney plant. We recently ceased production of phthalic slightly ahead of our May target date and are working through the next steps of our closure. We've recently extended our raw material supply in Australia and are looking to do the same in North America and Europe. While there is much [Technical Difficulty] overall health. And it's times like these that we've experienced in the past couple of years, which many times lead to that happening. So, it's something we will definitely be keeping our eyes on. Moving on to our outlook for 2025. As shown on Slide 29, we expect consolidated sales to reach $2 billion to $2.2 billion in 2025 compared with $2.1 billion in 2024. With lower volumes in PC and lower volumes in pricing in CMC partially offset by higher volumes and some pricing improvement in RPS and RUPS, I'm sorry, being the most likely outcome. On Slide 30, we're maintaining our adjusted EBITDA forecast of $280 million compared with $262 million in 2024. In line with the sales changes reflected on the previous page, we expect to see significant year-over-year improvement in RUPS, which we've already begun to realize in Q1, while PC will take a hit in profitability in line with its reduced sales volumes. Despite the lower top-line from CMC, we expect to see its profitability improve due to lower raw material costs and lower operating costs, and the Q1 results from this year are already reflective of that. As mentioned on our previous call, our entire organization underwent a comprehensive performance assessment to determine how high our potential performance could be, and the initial output of that assessment uncovered quite a bit of opportunity. We're now in the process of prioritizing and developing the detailed plans for how we turn these opportunities into results. And I expect that we'll have more shares as the year progresses and the impact that could have on the remainder of this year and future years. Slide 31 shows our 2025 adjusted earnings per share bridge and the improvement we expect in 2025, driven by higher operating earnings and lower interest expense. Accordingly, we're continuing to expect $4.75 per share in 2025 compared with $4.11 in 2024. On Slide 32, we're projecting net capital spending of $65 million in 2025 compared with $74 million in 2024. And based upon the run rate we saw in Q1, we're moving comfortably towards meeting that target or even coming in a little less. Now, the final point I will make before moving to Q&A is that, despite the extreme uncertainty that exists in the markets right now, we are fighting our way through it, and we'll come out the other side in an even stronger position due to the measures we've already taken as well as others that are near-term actionable. With no major capital expenditures looming and a portfolio of opportunities to act upon at our disposal, we find ourselves in a position to generate significant free cash flow over the next few years, which will be put to good use delevering the balance sheet and returning capital to shareholders. Now, I would like to open it up to any questions.
