Thank you, Nick, and good morning, everyone. We finished 2025 with quarterly adjusted earnings that was towards the high end of our expectations. Full year revenues for 2025 were $2.2 billion, led by 4% growth at Clean Earth, which was achieved through a mix of price increases and volume growth. This growth was offset by lower revenues at both Harsco Environmental and Rail due mainly to lower volumes as well as divestitures in the case of HE. Adjusted EBITDA for the year totaled $275 million. Clean Earth again realized record earnings and margins in 2025. For Harsco Environmental, market challenges persisted throughout the year, but we're pleased its performance improved as the year progressed. Our HE team executed well operationally and successfully renewed a larger-than-normal volume of contracts during the year. Looking forward, we're hopeful that underlying steel demand and production will improve for our customers, particularly in Europe, where trade protections are pending and expected to be implemented later this year. Any benefits from these trade actions in Europe are not considered in our guidance for 2026 at this point, and I'll share more on that shortly. At Rail, standard equipment demand remains weak and its ETO contracts continue to weigh on its earnings and cash flow. Despite sluggish demand, Rail's base business remained profitable in 2025 and its cash flow did improve. For the year, Rail's ETOs contributed an EBITDA loss of approximately $20 million and these contracts consumed roughly $40 million of cash during the year. We are pleased with the results of the actions the team has taken to improve efficiencies in the supply chain and manufacturing operations. We are continuing to take aggressive actions at Rail to manage ETO risk and address the challenging demand situation, including a recent additional restructuring to rightsize the business. We'll come back to the path forward for Rail in a bit, and you can find the full year financial summary in the appendix within our presentation. Now let me turn to our fourth quarter performance details, starting on Slide 4. In the fourth quarter, total revenues were $556 million, and adjusted EBITDA was $70 million. Both revenue and adjusted earnings were unchanged compared with the 2024 quarter with year-over-year growth for Harsco Environmental and Clean Earth, offset by Rail. Overall, our earnings performance was towards the higher end of our expectations with the primary driver being Harsco Environmental, which achieved its highest quarterly adjusted EBITDA for the year. HE benefited from better cost performance during the quarter and tax recoveries in Brazil, which were not anticipated. It also benefited from some price and various other adjustments at year-end. Meanwhile, Rail benefited from additional machine shipments in the quarter versus our earlier expectations. I'd note that corporate costs were higher than expected as a result of compensation expense linked to our share performance and other incentives. Our adjusted diluted loss per share was $0.17 for the quarter, excluding the impact of unusual items. These unusual items totaled $57 million pretax and included the following: $15 million of costs directly related to the sale of Clean Earth and the spin-off of New Enviri. It also includes $7 million to accelerate the vesting of certain stock compensation to mitigate the tax impact of the company, which can also be considered as deal related and it includes $24 million of additional estimated costs to complete our ETO projects with SBB and Deutsche Bahn, which we will discuss further. Lastly, our adjusted free cash flow for the quarter was $6 million and for the full year, we ended at negative $15 million. This outcome was better than our latest guidance and reflects improved collections in the fourth quarter. For the year, Harsco Environmental and Clean Earth generated more than $160 million of free cash flow. This total, however, was offset by an interest burden of more than $100 million and Rail's negative cash flow of more than $50 million, both of which are expected to improve as part of New Enviri. A schedule detailing our free cash flow by business is included in our press release. Please turn to Slide 5 and our Harsco Environmental segment. Segment revenues totaled $257 million, an increase of 7% compared with the prior year quarter and adjusted EBITDA totaled $48 million, which translates to a margin of nearly 19%. The year-over-year earnings increase can be attributed to a number of factors, including higher service levels, improvement actions at certain underperforming sites and FX as well as tax recoveries in Brazil. These positives were partially offset by lower product contributions which can mainly be attributed to our ALTEK business. HE's results in Q4 were supported by a modest increase in steel production at our customer sites with growth most prominent in India, the Middle East and North America. Steel output in Europe or our largest market, however, remained very weak in the quarter. And while customer steel output overall did improve somewhat in the second half of the year, we continue to see significant room for upside. If implemented, we expect the trade measures contemplated in Europe mentioned earlier to support its steel industry with benefits for Harsco Environmental possible during the back half of 2026. Proposed changes were recently approved by the EU trade Committee and are now before the full parliament. Our steel customers in Europe expect these policy changes to become effective at the beginning of July this year. Now please turn to Slide 6 to discuss Clean Earth. For the quarter, revenues totaled $244 million, and adjusted EBITDA reached $38 million. Hazardous waste revenues grew approximately 3% through a mix of price and volume. And this increase was partially offset by a lower volume as a result of project-related work completed in the prior year quarter and mix changes in soil dredge materials. CE's adjusted EBITDA margin was just under 16% for the quarter. which includes the impact of higher incentive compensation. Now please turn to Slide 7 and our Rail business. Rail revenues totaled $56 million and its adjusted EBITDA loss was $4 million in the fourth quarter. Compared with the prior year quarter, lower volume across all business lines as well as a weaker business mix led to the decline in adjusted earnings. As we have commented in prior quarters, we have been seeing weakness in the North American market, resulting in contracting volumes. Our Rail team has done a nice job during 2025 to drive completion of several smaller ETO projects, improve our manufacturing processes and have also addressed the weaker demand by taking restructuring actions throughout the year to resize our capacity accordingly. Now let me provide a brief status update on Rail's large European ETOs. Russell will provide some perspective later as well. On the Network Rail contract, we continue to work towards some important project milestones while we continue discussions with our customer to improve the financial terms of the contract. Delivery and on-site testing of the first machine is planned for the summer, soon after which we expect to finalize our revised contract negotiations. For SBB, most of the first group of vehicles, which includes 48 wagons have been delivered and accepted by the customer. The remainder are expected to be accepted by the customer by end of Q3. Homologation for the second vehicle type, which will total 11 machines has started, and we expect to complete delivery of these machines by mid-2027. For Deutsche Bahn, the first 3 vehicles are scheduled to be completed and undergo homologation in the coming quarters under the existing contract. Now let me turn to our outlook on Slide 8. As Nick mentioned earlier, we're targeting a midyear closing for the sale of CE as well as the spin-off of New Enviri. Post the close date, we will likely be providing certain transition services to Veolia for some months, and 2026 accordingly will be a mixed year of Enviri and New Enviri. Therefore, today, we're only providing guidance for Harsco Environmental and Rail, the 2 businesses that will exist within New Enviri. This outlook doesn't contemplate any major improvements in economic or business fundamentals including within the European steel industry as a result of trade protections and in the case of Rail, our expectation is that demand will soften this year relative to 2025 with overall volumes reaching historic lows. While our outlook does consider the cost-out actions and improvements implemented in recent months within both Rail and HE, the benefit of these actions won't reach a full run rate until the second half of the year. Furthermore, our outlook does not incorporate any benefits from other projects underway within the company that Russell will speak to shortly. For Harsco Environmental, adjusted EBITDA is expected to be within a range of $170 million to $180 million. This range reflects that volume from new site startups a modest improvement in customer steel output and cost-out initiatives will be offset by [ cost ] and certain items not repeating in 2026. For Rail, we expect an EBITDA loss of between $26 million and $19 million. This outlook reflects lower demand for standard equipment and contract services as well as lower capacity utilization at our main plant, which will be partially offset by the restructuring actions I mentioned earlier. These expectations translate to pro forma EBITDA for the year of approximately $140 million for New Enviri. This figure is $5 million higher than what we presented in November when we disclosed the Clean Earth sale and reflects pro forma corporate post significant rightsizing of our corporate team and costs. The specific changes contemplated at corporate have been already announced internally and will be fully implemented after the close of the Clean Earth transaction and the completion of transition services. For free cash flow, we anticipate cash generation to be modest for New Enviri in 2026. I'd remind you that our free cash flow is typically negative in Q1 as a result mainly of our bond interest payments. For the year, HE and Rail cash flows are projected to improve compared with 2025, but we expect Rail ETOs to remain negative in 2026 under the existing contracts. Let me conclude on Slide 9 with our first quarter guidance. Here, I'll simplify and note that segment performance for these 2 businesses is projected to be lower year-over-year as well as lower compared to the just completed fourth quarter. These changes reflect lower volumes of demand, low volumes or demand for both businesses as well as contract exits for HE. This guidance also reflects that certain Q4 items such as the Brazil tax credits won't be repeated in the first quarter. Now over to Russell.
