Thank you, Nick, and good morning, everyone. We had a solid finish to 2024 in the fourth quarter, which was broadly in line with our expectations. Full-year revenues for 2024 were $2.3 billion. Adjusted EBITDA reached $319 million, which was up 4% year on year as reported or up 11% on an organic basis. This was our highest adjusted EBITDA in ten years. From a segment standpoint, HE performed well while facing challenging market conditions. Clean Earth drove our growth by again delivering record earnings and margins. As Nick said, Clean Earth's EBITDA in 2024 was more than double its earnings in 2021, our first full year of ownership. We are very pleased with the execution at Clean Earth and the returns now being generated on our initial investment. Enviri's free cash flow for the year was a negative $34 million. This was a result of cash usage for our large engineer-to-order projects in the rail business as well as delayed collections in our base rail business with certain shipments being pushed out into 2025. HE and Clean Earth together generated free cash flow of more than $190 million in 2024, an improvement over 2023. Our covenant net leverage ratio at the end of 2024 was 4.07 times, an improvement from the beginning of the year. Now let me turn to our fourth-quarter performance details starting on slide five. Similar to quarter three, we faced some headwinds in Q4 within our Harsco Environmental and Rail businesses as a result of market conditions, customer shipment delays, and supply chain pressures. However, our operating teams performed very well, and I am pleased that we delivered adjusted EBITDA within our guidance range for the quarter. We saw positive momentum in the quarter. Clean Earth delivered over 25% EBITDA growth and record Q4 margins. Rail showed strong quarter-on-quarter improvement in both EBITDA and free cash flow. And importantly, these positive trends in Rail are expected to continue in 2025. Difficult conditions within the global steel market. So net-net, a positive quarter for the company. In the fourth quarter, revenues totaled $559 million, which was little changed from the prior year quarter after adjusting for the impact of FX translation and business divestitures. Adjusted EBITDA was $70 million, which is 5% higher year over year on a similar organic basis. Again, reflecting the strong improvement and growth at Clean Earth. Relative to guidance, Clean Earth and Harsco Environmental performed in line with our expectations. In HE, incremental FX and volume pressures were offset by better cost performance. Clean Earth's performance was steady and strong in Q4, while Rail results were modestly below our target due to shipment delays in North America, which will be realized in 2025, as well as cost adjustments on a few small projects, which will also be completed in 2025. Our adjusted diluted loss per share was four cents for the quarter. This figure excludes the impact of special items totaling $90 million. This is a significant amount of such charges and reflects the fact that we are actively and aggressively working to address certain issues, including some legacy matters. In the fourth quarter, this included roughly half a dozen items in Harsco Environmental and Rail, with about $40 million of the $90 million representing asset impairments or write-downs that are non-cash in nature. In HE, these items include exit costs following a site closure in the UK, an asset impairment for an underperforming US site where improvement initiatives are underway, and anticipated costs to address an environmental matter in the Middle East. In Rail, the charges include further adjustments and a goodwill impairment charge. Q4 was an unusual quarter as we work through these issues, and we understand the importance of minimizing the impact of special items in the future. Lastly, on this slide, adjusted free cash flow for the quarter was $8 million, reflecting a $42 million improvement versus the third quarter of 2024, driven by working capital improvements in Rail, which we had expected. Our fourth-quarter cash flow also benefited from the timing of interest and lower pension payments. Clean Earth and HE generated over $40 million of free cash flow in Q4 combined. Rail's free cash flow in the quarter netted out to nil, with positive cash generation from the base business offset by usage from its large ATO contracts, which continue to weigh on overall cash generation as we have discussed previously. I will come back to Rail and our outlook in a bit. Finally, as you may recall, we extended our revolver and accounts receivable facilities in Q3 of 2024. Earlier this month, we amended our credit agreement to provide additional cushion under our covenants and strengthen our financial flexibility. We also increased the size of our accounts receivable facility by $10 million. Overall, I am pleased with our capital structure. While our next debt maturity is not until 2027, we expect to continue to be proactive and opportunistic in addressing future maturities. Please turn to slide six and our Harsco Environmental segment. Segment revenues totaled $240 million. Adjusting for an FX impact of $14 million and a divestiture impact of $26 million, the organic decline in revenues was 4%. This change reflects lower service levels as a result of weaker steel production as well as site exits, which relate to the site closures we discussed in October. Adjusted EBITDA for the quarter totaled $41 million compared with $56 million in the prior year quarter. Operating rates or production rates at our customer sites are very low in Q4. For customers that provide this information, mill utilization was below 73% in the quarter. And relative to the prior year quarter, steel production was weakest in Europe, North America, and the Middle East. The fourth quarter is traditionally a soft period for the steel industry as well, and there is some positive steel price momentum in the marketplace today. And while it is too early to call this a trend, higher steel prices often lead to increased production and mill service activity. As Nick mentioned, HE's operating leverage to higher production levels remains significant, positioning us well to benefit when markets recover. Next, please turn to slide seven to discuss Clean Earth. For the quarter, revenues totaled $241 million, and adjusted EBITDA reached $36 million, up 26% year on year. The increase in revenues is attributable to price initiatives, and the growth in EBITDA reflects higher prices as well as cost efficiencies. The Clean Earth team continues to realize benefits from its efforts to drive down costs within its major spending categories, the largest of which include transportation and disposal. Clean Earth also generated over $30 million of free cash flow in the quarter, and its free cash flow for the year exceeded $100 million for the second consecutive year. Overall, these very strong results for Clean Earth reflect positively on the leadership in the business, who many of you met at our Investor Day, and the high level of execution throughout the Clean Earth organization. Now please turn to slide eight in our Rail business. Rail revenues totaled $77 million, and its adjusted EBITDA was $2 million in the fourth quarter. The increase in revenues is the result of higher equipment and technology volumes offset by lower aftermarket sales. The year-on-year EBITDA change can be attributed to lower aftermarket sales as well as a less favorable business mix, including the contracting services work performed in each quarter. Relative to the third quarter of 2024, Rail's adjusted earnings improved, as did its free cash flow, which I mentioned earlier. We continue to strengthen the Rail team while also making progress in addressing Rail's supply chain and operational challenges. Our operations team is driving several improvement projects, which will be completed during 2025 and will progressively improve our ability to deliver expectations and increase the throughput and capacity of the operation. We are investing in the new IT ERP system for Rail, which we also expect to drive operating improvements by providing better visibility and control for our team. Making progress on our large engineer-to-order contracts is also a top priority for the company. Additional forward losses of $13 million under these contracts were recorded in Q4 as we continue to make progress in manufacturing the equipment for our customers. We also continue to work with these customers to clarify future schedules and to limit our financial exposure. We will provide you an update on these efforts when appropriate. In an effort to provide more clarity on Rail's underlying performance, we have included slide nine in the deck detailing the revenue, EBITDA, and free cash flow split for its ETOs and base business in 2024. Let me make a few observations. Demand for Rail's standard equipment and services remained strong. Base business profits are significant, and margins are steady, with a healthy conversion to cash. Our largest ETOs are reported at zero gross margin given our forward loss provisions, but we have overheads that support these projects. And lastly, we have been consuming cash through working capital for our ETO projects as we build the related equipment in advance of delivery to our customers. Now specifically, Rail's adjusted EBITDA in 2024 totaled $9 million, including a loss of $20 million on its ETOs and a positive contribution of $30 million from its base business. And Rail consumed $62 million of cash in the year. The ETOs consumed approximately $79 million of cash, while the base business generated a positive $17 million. Overall, Rail's base business is a valuable part of our portfolio. And as we have discussed before, the ETOs are for now a headwind to the business and company for that matter. We hope this additional detail is helpful, and importantly, the impact of Rail's ETO contracts is set to improve in the future, as certain contracts end and others mature starting in 2025. Now let me turn to our 2025 outlook on slide ten. Enviri's full-year adjusted EBITDA is expected to be within a range of $305 to $325 million, which represents 5% organic growth. Revenues are expected to increase less than that on a similar basis. And note that the revenue headwind from divestitures and FX is roughly $100 million year on year. Importantly, our EBITDA change reflects a continued shift in our business mix among our two largest segments, which have very different valuation considerations. For the year, Clean Earth's EBITDA is projected to grow double digits, and this growth will be offset by HE on a reported basis, including FX and divestiture impacts. Free cash flow is anticipated to increase to between $30 million and $50 million. This reflects considerable improvement in 2025, with the increase largely due to Rail and pension. A $40 million improvement in Rail's free cash flow is expected as some small ETO projects conclude and we are paid by our customers. The Rail cash flow improvement in 2025 is also driven by an improved base business with lower inventory and higher collections. The other large change for 2025 is that our cash pension contributions will decrease by approximately $20 million. For the three large ETO projects, we expect to start delivering a significant portion of the equipment to our customers in 2026, at which point we expect cash flows on these three projects to start improving. Capital spending of $130 to $140 million is planned for the year, with less spending in HE and higher year-on-year spending at Clean Earth to drive its growth. Our per-share guidance for adjusted earnings ranges from a loss of one cent to a loss of twenty-five cents. This range considers that our interest expense will decline modestly, and various other assumptions are included in our press release. Now let's turn to our segment guidance on slide eleven. Harsco Environmental's profitability is expected to be lower year on year. The negative impact of a stronger US dollar and divestitures is nearly $20 million. Operating improvements and new contracts will offset a weaker service mix and contract exits. We have not assumed much improvement in underlying steel production at our customer sites. For Clean Earth, revenues are anticipated to grow mid-single digits, with this increase slightly more weighted to volume over price. Clean Earth's EBITDA will grow at a low double-digit rate, with its margin approaching 17%. And I would note that it had a bad debt benefit in 2024 that will not recur in 2025. Net-net, we again expect a strong contribution from its revenue lift in 2025. Rail's adjusted EBITDA is projected to increase approximately 50% at the midpoint, with the improvement driven by price, volume, and efficiency initiatives. And lastly, corporate costs are expected to be approximately $38 million in 2025, with the increase largely due to non-cash equity compensation. Let me conclude on slide twelve with our first-quarter guidance. Q1 adjusted EBITDA is expected to range from $57 million to $62 million. Clean Earth's results are expected to be above the prior year quarter, while HE and Rail are expected to be lower year on year. For HE, the change reflects the impact of divestitures, site closures, and exits. We do have new contracts in 2025, but these positive impacts will not offset the exits until the second half of the year. For Rail, the change reflects the lumpiness of the business, particularly in Q1 each year. We have anticipated a weaker business mix this year. Lastly, on Q1, we expect free cash flow will be negative as a result of business seasonality as well as the timing of interest and incentive compensation payments. Thank you. And I will now hand the call back to the operator for Q&A.
