Thanks, Steve, and thank you to everyone joining our call today. Let's start with a few first quarter highlights on Slide 3. Looking across the global macro environment, economic uncertainty continues to dominate the narrative. Against this backdrop, everyone here at Olin continues to focus on the path we laid out during our Investor Day, while closely managing the factors within our control and advancing our value creation strategy. As a result, we're increasing our cost reduction target to $50 million to $70 million related to productivity and structural cost improvements for full year 2025. During the first quarter, our Chlor Alkali products and Vinyls business exceeded expectations as several planned and unplanned industry outages reduced first quarter chlorine and caustic soda supply. In response, we delayed the planned first quarter outage at our Chlor Alkali facility in Freeport, Texas, to meet customer needs and we're pleased to help many customers during the tight market conditions. This is in line with our value-first commercial approach and as we've consistently said, Olin is ready to raise operating rates to meet demand at fair values. We view this as a positive true point for our Chlor Alkali loaded spring that will be more apparent as we emerge from this extended trough environment. During the first quarter, we also saw stable ECU values continue with positive pricing trends into the second quarter. In our Winchester division, domestic and international military ammunition volume continues to grow while commercial sales continue to be weak as retailers destock, coupled with lower consumer sales. Also during the first quarter, Olin took advantage of historically narrow spreads and successfully refinanced our nearest debt tranche through a bond issue and bank refinancing. This pushed our nearest debt tower out to 2029 and positions us very well to weather the uncertain environment we see today. As we manage through this challenging economic environment, we're taking important steps to advance our strategy and strengthen our business. Slide 4 reviews several of our recent actions. Our optimize and grow the core strategy introduced during our December Investor Day outlines our path forward and we took several steps to advance that strategy in the first quarter, continuing our commitment to a value-first commercial approach, accelerating structural cost reductions and maintaining our disciplined capital allocation framework, all while not losing focus on the high-value growth opportunities laid out in December. As an example, we made solid progress to implement our Winchester growth strategy. I'm pleased to report that Winchester has been awarded a three-year contract extension to continue operating the Lake City GOCO2 Ammunition facility through 2030. Additionally, we closed the acquisition of AMMO Inc.'s Ammunition assets. We've also been focused on enhancing our organizational accountability. We've aligned each employee's incentives with our corporate goals and strengthened our equity plans to increase engagement and retention. Also, we consolidated our chemicals commercial talent to our Houston office to facilitate greater cross collaboration and teamwork. And finally, we established Clayton, Missouri as our Winchester headquarters. Now let's turn to Slide 5 to review our Chlor Alkali Products and Vinyls results. First quarter CAPV EBITDA was up slightly with increased chlorine and caustic volumes as we continue to focus on value and push for price gains on each side of the ECU. We expect caustic to remain the stronger side of the ECU and see positive pricing trends going into the second quarter. As mentioned earlier, we delayed the start of our planned Freeport, Texas turnaround to opportunistically capture spot demand created by planned and unplanned industry outages. During the first quarter, we reengaged with several chlorine customers seeking interim supply. The turnaround delay is reflected in our updated expense data on Slide 17. This delay will result in $33 million higher sequential turnaround expense. Despite this headwind, we still expect to deliver sequentially similar Chlor Alkali adjusted EBITDA in the second quarter. As we continue to navigate this unusually long trough, Olin's ECU values and volumes have proven remarkably resilient across the past six quarters as we implement our disciplined value-first commercial approach. PVC was another highlight in the quarter as we delivered our first shipments of Olin PVC during March, marking a key milestone for our PVC business development. In addition to our entry into the PVC market, we're adding value to every ton of EDC we toll with ChemOne. As we discussed at our December Investor Day, we're exploring potential long term PVC strategic opportunities, including long term commercial arrangements, available production technologies, and the evaluation of joint venture partners. With respect to current tariffs, we do not expect the direct impact on CAPV to be significant. Olin's export sales, mainly caustic soda and EDC, are generally sold to low tariff countries. One potential positive effect may be to tighten U.S. caustic supply as tariffs challenge the economics of Asian imports to the U.S. West Coast and European imports to the U.S. East Coast. Now let's turn to Slide 6 for a brief look at our Epoxy results. First quarter Epoxy sales improved sequentially, reflecting an increase in both resin prices and volumes. However, the margin benefits of improved pricing were more than offset by higher costs. Last month, the U.S. Commerce Department issued their final Epoxy antidumping decision. Olin was encouraged that the antidumping duty percentages for selected countries were raised beyond the preliminary determination. However, we remain concerned that the Commerce Department lowered the duty percentages for certain countries, in particular South Korea. The European Union announced their provisional Epoxy resin antidumping duties during the first quarter and expects to conclude the investigation by issuing definitive measures during the third quarter 2025. Today, South Korea, the largest importer of Epoxy resins to the European Union, unfortunately remains exempt. Bulk Epoxy resins subject to antidumping duties represent less than 25% of our overall Epoxy division sales. Current antidumping duties provide minimal upside value. We will continue to advocate for fair trade practices here and in Europe, pursuing every available avenue. Looking ahead, building and construction, automotive and consumer electronics demand remain weak in the U.S. and Europe. We are seeing mild seasonal demand improvement, but nothing we would consider as demand recovery. Second quarter Epoxy results will include a planned Stade, Germany, turnaround estimated to present a $10 million sequential headwind. As a result, Epoxy earnings are expected to remain negative. Slide 7 provides an update on our Winchester business. Winchester domestic and international military sales continue to grow as anticipated. Military project spending accelerated through the first quarter and is expected to continue gaining momentum throughout 2025. Commercial ammunition demand continues to be weak. We're seeing mid single-digit pullback across sporting goods, hunting and gun sales. However, commercial ammunition sales have declined more than the sporting goods category. Ammunition retailers are destocking in parallel with consumers. You may recall that ammunition retailers built very high inventories during the first half of last year in advance of expected propellant shortages and the Presidential election. Lower out-the-door retail sales have made destocking a lengthier process, which will likely stretch into the second half of 2025. Winchester costs for metals are rising due to tariffs and tight supply. Propellants also continue to present a cost headwind. Although, Winchester buys most metals locally, we still realize tariff-related price inflation on the domestic price of steel, aluminum, and copper. At the same time, tariffs may also provide a tailwind for Winchester as ammunition imports will now carry at least a 10% penalty. And in order to reduce U.S. trade imbalances, country-level tariff negotiations are promoting the increase of defense-related U.S. exports, including small-caliber ammunition. Now turning to Slide 8, this past month, we were pleased to close on the acquisition of AMMO Inc.'s manufacturing assets. Winchester's timing for the purchase of this state-of-the-art ammunition production facility was ideal. We were able to acquire a modern plant with a skilled workforce at a highly-attractive adjusted purchase price of $56 million. We've begun integrating this new plant to optimize production across our assets in order to begin realizing our target synergies and extending our scale benefits to this new production site. As detailed during our December Investor Day, Winchester is an iconic brand and an excellent platform for growth. In addition to being immediately accretive, the showcase expertise we acquired will support a new area of growth for Winchester. The value-creation potential of our Winchester platform is significant and this acquisition absolutely exceeds our investment hurdles at less than approximately 1.5 times adjusted EBITDA, including synergies. Let me now turn the call over to Todd Slater to walk us through some financial highlights.
