Thanks, Brad. Before I dive into each of the businesses, I would like to provide our perspective on the recent Supreme Court ruling, which vacated tariffs under IEEPA. Prior to the ruling, we were estimating a tariff impact on our business of around $5 million-$6 million in 2026. Removing the IEEPA tariff and replacing it with a worldwide tariff of 10% essentially reshuffles the deck and leaves us in a slightly better position. Of course, these are only in place for 150 days, the administration has promised to use this time to put more permanent tariffs in place, it remains to be seen how it will impact our business. Perhaps a greater concern are potential tariffs under Section 232, which has an ongoing investigation into refined copper imports. We do not import copper for our products, as we use domestically sourced scrap copper, for unhedged copper requirements, any tariff on refined copper will increase the market price of this key raw material for our PC business. The uncertainty of tariffs continues. The numbers seem to change from day to day. While I am providing our most current view, that can obviously change quickly. For now, I am going to review the market outlook for each of our businesses, starting with Performance Chemicals on page 20. Let me lead with the good news. We are projecting a top-line increase of approximately 11% in 2026, driven entirely by market share expansion in both our residential and industrial product lines. A large component of our Catalyst initiatives for PC centered around converting commercial opportunities that we knew were in play coming into 2026 as new business. We realized success on a number of accounts, refocusing our attention on serving the customer, while also demonstrating the value of our R&D and tech service capabilities to convert a portion of business to new technology. In addition, our PC team continues to be focused on commercializing the next generation of reduced copper wood preservatives and in-demand fire retardants. Moving to the external market data, we interpret market sentiment as neutral to slightly positive for 2026, with our internal models reflecting overall flat market demand. Existing home sales in 2025 were flat compared to 2024, and while a fourth quarter upswing gave some hope of stronger existing home sales activity in 2026, January's numbers were disappointing as they registered an 8% month-over-month decline, getting the year off to a tough start. The average mortgage rates fluctuated between 6.2%-6.3% in the fourth quarter, down from earlier in the year. The rates are currently at about 6%, and expected to moderate slightly in the near term, although that is not expected to have a meaningful impact on the housing market. The leading indicator of remodeling activity, or LIRA, is forecasting year-over-year growth in home renovation and repair spending of 2.9% in early 2026, and eventually easing to 1.6% growth by the fourth quarter. Building product sentiment remains neutral, with cautious optimism in select commercial and infrastructure segments. Listening to our customer base, it seems the disappointment of 2025 is still fresh in their minds, and so they are reluctant to build in any significant rebound until they can get clearer signals. This has our model for 2026 baking in flat organic volumes for residential products, with a modest low to mid-single-digit volume increase expected for our industrial product segment, driven by growth in utility pole demand. On the cost side of the equation, excluding copper, we are expecting a mix of increases and decreases in our raw materials to mostly balance out and have little impact. Copper prices have continued their steady rise over the past year and currently are 25% higher than average prices for 2025. Because of our hedging strategy, we are mostly insulated from the increase at current price levels, assuming scrap copper pricing continues to behave as it historically has. The price separation between the LME and COMEX indices that we discussed last year has not been an issue recently, but changes in the tariff environment could see this return. In the meantime, we continue to work to manage this risk. If the copper markets do not abate as we enter into contract discussions later in 2026, current prices would represent a $50 million pricing pass-through necessary to account for the increased copper costs. The Catalyst benefits for Performance Chemicals targeted in 2026 are mostly commercially driven and are already secured, where PC results ultimately end up in 2026 will depend more on the direction of base demand compared to our flat outlook and the uncertain cost environment driven by tariffs. Moving on to our utility and industrial products business, shown on page 21. Market sentiment remains bullish, mainly due to increasing electrical demand related to build out of AI infrastructure. In addition, it is anticipated that crypto mining, EV development, and new manufacturing will contribute to increased electrical demand over the next five years. Utilities are being pressured to limit price increases resulting from higher demand, and data centers owned and operated by large tech companies are expected to be required to share the resulting cost burden with consumers. Now, we entered 2025 with a clear objective to grow our business outside of our traditional regional markets in the U.S., and we were able to do that, growing our non-traditional markets by 17% on the top line while keeping our core regional markets flat, which resulted in an overall 6% sales increase. We are targeting an even greater top-line performance in 2026, driven once again by growth in targeted regions, added sales from the pole procurement acquisition made in late 2025, and a modest organic market improvement after lower than expected growth last year. In 2025, we made investments in our distribution assets, fiber supply, technology platform, and sales team, including adding new sales leadership at the beginning of 2026 that we believe position us as a formidable competitor on new accounts. As to the acquisition I referenced, in December, we acquired a small business specializing in the procurement of Douglas fir fiber, which is traditionally used for transmission poles. This is important for solidifying opportunities to grow our sales base by adding to the opportunities we have historically been shut out from, due to not having that wood species in our portfolio. It represents our next step in building out our portfolio in a measured way. To quell any worries that we would spend significant amounts of capital in the hopes of future business, this transaction represents a lower cost, lower risk approach to securing a new critical supply chain. This will open doors in existing markets while also providing a platform to potentially build from as we think further about the Western markets. While sales showed modest gains in 2025, we took a step back on our cost management in UIP last year. That makes this business ripe for the planning and execution discipline that Catalyst fosters. Opportunity abounds on the cost front in UIP. We will be going after it hard in 2026. Of the improvement targeted for UIP in 2026, over three quarters of it is cost related. Part of the cost improvements relate to a consolidation of production resulting from the recent idling of our plant in Vance, Alabama, mentioned earlier. That production has moved to our nearby facility in Kennedy, Alabama, which will realize the benefits of improved cost absorption. Vance will remain in our network, but not operate as we continue to monitor our long-term manufacturing requirements in this important growth market. The market outlook for our railroad products and services business is summarized on page 22. Railroad industry consolidation continues to impact market trends and the pressure to improve operating performance, resulting in reduced capital spending by our customers. As mentioned on prior calls, for the second straight year, our railroad customer base reduced their forecasted tie requirements communicated to us heading into the calendar year, as they pulled back on their tie programs. Thankfully, this past year, we were able to balance out the lower than anticipated volumes with some aggressive cost actions, improving our profitability in this business to a level not seen in a decade. As we approach customer discussions for 2026, two Class I customers indicated an additional pullback in volume for this year, which would have a significant impact on our RPS profitability without some counteraction. We believe we have been able to primarily offset that impact in 2026 by agreeing to provide price relief while receiving a larger contractual commitment from one customer, as well as an extension of our current agreement. We are also mitigating the impact of lower volume from a second customer by idling production capacity and consolidating operations across our remaining treating network, as mentioned earlier. There is a lot going on with the Class I customer base, but the main point for our shareholders is that we are in the most competitive position to capitalize on a Class I market dealing with a lot of uncertainty right now. While the pie may be smaller, our piece of it is expected to grow to volumes that we have not seen since 2017. The commercial crosstie market remains very competitive, but we continue to make inroads there, and as of the end of January, have the highest backlog that we have had in the past five years. As for operations, we have realized much of the low-hanging fruit over the past 18 months and are looking to maintain the gains we have made heading into 2026. Much of the benefit has been derived by doing more with less. In 2025, we had 1% more in crosstie sales than 2024, with 38 or 7% fewer people than where we ended 2024. In the crosstie portion of our business, we are down by 105 people, or 16%, compared to our peak employment level at April 2024. The idling of the plant that I mentioned will result in another net 76 employee reduction, which will serve to offset anticipated price reductions. Sawmills are experiencing the impact of the industry pullback, resulting in sharply reduced production and widespread mill closures. It remains to be seen what long-term impact this could have on hardwood availability and pricing, but in the near term, it is a buyer's market. Catalyst benefits included in our 2026 projections primarily relate to plant consolidation, material waste reduction, and commercial and operations improvements. The outlook for our CMC business is summarized on page 23. Overall, the CMC market remains in turmoil, as evidenced by sharply reduced financial performance realized in Q4. Structural improvements made in 2025 by closing our phthalic anhydride plant, along with successfully executing on several Catalyst initiatives, are projected in the near term to be offset by higher net global coal tar costs, reduced throughput as a result of a key raw material supplier exiting the market, and pricing pressure brought on by trying to maintain business in a troubled market. On the plus side, we do have a strong base of raw material supply locked down for several years in each of our geographic markets, which assures us a certain level of throughput. Also, as mentioned during my RPS commentary, I believe we are positioned to grow our share of the crosstie market, which will provide a strong baseload of creosote demand. The strong connection of our U.S. and European logistics network also keeps us on par with our major competitor. It also provides an advantage against other European competitors, more reliant on less attractive export markets to supplement their domestic customer base. We think we will see some capacity rationalization in Europe at some point as it gets tougher to withstand the current market headwinds. The loss of tar supply in the U.S. from a supplier that is closing their coking operations presents a challenge to U.S. operations. It presents an opportunity for our European operations to increase their share of the market as they have ample raw material availability. Catalyst benefits targeted for CMC in 2026 cover all aspects of the business, from production to logistics, procurement, and sales. Our greatest opportunity for improvement remains in CMMC, I have confidence that we will see it realized over the next three years. As shown on slide 24, we are about a full year into our Catalyst transformation and executing successfully on many initiatives. The $46 million of benefits that we realized in 2025 more than offset the $40 million something impact of lower sales on our PC business, and almost got us back to our 2024 adjusted EBITDA level. As we have continued to evaluate Catalyst opportunities, we have been able to increase our pipeline from what we previously communicated, and now believe we can generate up to $75 million of benefits in the 2026 through 2028 time frame, compared to the $40 million that we had expected back in November. The main driver for the increase is due to the optimization of our manufacturing network, and we were also able to add to each of the other targeted functional areas. Of the $75 million estimated over the next three years, we have targeted between $20 million and $40 million as achievable in 2026. Like 2025, we are experiencing headwinds that are preventing the full impact of the benefits from being reflected in EBITDA, although adjusted EPS and operating and free cash flow should both increase significantly. I will reiterate what I said back in November. When I look at our full potential, I see an organization that should be able to deliver 15%+ margins on a consistent basis, an organization that should be able to drive earnings improvement of greater than 10% on average over the next three years. An organization that should be able to reduce leverage to the low end of our stated range, below two and a half times, driven by significantly greater free cash flow generation. What we have targeted to be $300 million or more over the next three years. Our path to get there is the continued evolution of our portfolio that would make PC and RUPS a larger share of our top and bottom line as we focus on our more structurally sound businesses that have opportunity for growth and have proven to consistently generate higher margins with lower capital requirements. You are seeing that playing out in our 2026 projections, which I will move on to now. As shown on slide 26, our consolidated sales guidance of $1.9 billion-$2 billion in 2026 compares with $1.88 billion in 2025, with PC and RUPS making up 80% of our top line, the highest percent of total sales in company history, and closing in on our 85% of sales target. On slide 27, we are forecasting adjusted EBITDA of $250 million-$270 million in 2026, compared with $257 million in 2025. The biggest risk to achieving the midpoint include realizing the lower end of our Catalyst capture rate and seeing further end market softness. Additional risks are higher costs, driven by tariffs or other factors, and extended operational disruptions. Our biggest opportunities of exceeding the midpoint are if we meet the higher end of our Catalyst capture rate and see end markets strengthen. Slide 28 shows our adjusted earnings per share bridge, reflecting a range of $4.20 to $5.00 per share in 2026, compared with $4.07 in 2025. At the midpoint, the contribution from operations, interest savings, lower depreciation and amortization, and benefits from a lower share count are partly offset by higher taxes from higher net earnings. While we do not provide quarterly earnings guidance, it is worth noting that our first quarter this year will be the weakest of the four. This is due to the greater than normal effect of the severe winter weather that has impacted our operations and shipping schedules. In addition, there are several Catalyst initiatives that are in earlier stages and will not pick up momentum until the second and third quarters. On slide 29, as I have been signaling for the past several quarters, we are expecting to see a sizable jump in both operating cash flow and free cash flow this year. As a result, this will provide the most cash we have had for debt paydown since 2020, when we received the cash proceeds for selling our KJCC business. Not only would operating cash flow and free cash flow represent new highs at these projected levels, but more importantly, 2026 will represent an inflection point for our step change in cash generation, as we expect these new higher levels to become the norm. At our current market cap, this equates to a better than 15% free cash flow yield. This places Koppers Holdings Inc. at the top end of whatever industry you want to compare us to and provide several attractive options for how we deploy our excess cash. This also implies about a 50% opportunity in our share price just to bring it back to the current 10% yield level based on 2025 free cash flow. The foundation we have built over the previous five years has set us up to create significant shareholder value over the next several years. I am confident we will deliver. We still maintain leading shares in niche markets that utilize our essential products with low capital requirements in the near term and rising cash flows to deploy towards further reducing our share count and our debt. I would like to open it up to questions.
