With that said, I'd now like to turn the call over to Vince Arnone. Vince, please go ahead. Thank you, Devin. Good morning, and I'd like to thank everyone for joining us on the call today. Given that we last spoke not that long ago in connection with our year-end results, I'll keep my commentary brief today. Although we've begun the year more slowly than anticipated in our APC and FUEL CHEM business segments, we expect that our performance for these businesses will show steady improvement as we move through 2024. In addition, we are very encouraged by the progress we are making at our dissolved gas infusion, or DGI business initiative, and we ended the quarter in a very strong financial position with cash, cash equivalents, and investments of over $32 million and no long-term debt. Now, let's discuss our results for the Q1 in more detail. As a general statement, our results reflected the impact of customer-driven delays in the execution of existing contracts in our APC business segment, while our performance in FUEL CHEM was impacted detrimentally by historic warm weather across the US that affected unit dispatch and by unscheduled plant outages. For the APC segment, I remain pleased with our ongoing execution of existing projects and our team's current business development activities, which continue to reflect an increased focus on global emissions protocols across a variety of fuel sources. In 2023, we benefited from the continued adoption of our ULTRA, SCR, SNCR, and FGC emissions control solutions at natural gas and coal-fired units in the US, Europe, South Africa, and the Pacific Rim, and I expect this to continue into 2024 and beyond. Independent of the potential impact of favorable regulatory outcomes, which I will discuss shortly, we are well positioned to take advantage of current industrial market trends, which include plant capacity expansion across several industries, the incentivized use of small turbines to replace traditional, less clean power generation, the development of the biocarbon industry, the continued emphasis on decarbonization on a global basis, and the focus on using our ULTRA systems as the safe source of ammonia for SCRs at hospitals and universities across the US We are providing proposals to customers for both near and longer-term needs, regardless of regulatory drivers, and we are currently watching the progress of $5 million to 10 million in APC contract opportunities that could close in our favor before the end of the second quarter or shortly thereafter. Now, on the regulatory front, we continue to monitor progress related to the adoption of the US EPA's Cross-State Air Pollution Control regulation to meet the Good Neighbor requirements of the Clean Air Act, which we believe can be a potential catalyst for APC growth in 2024 and for the remainder of this decade, as utility and industrial customers explore ways to further reduce NOx emissions. Over the past several months, we have received and responded to multiple requests for budgetary proposals as customers prepare to address the upcoming compliance requirements as part of their capital budget planning for this year and beyond. As discussed on previous calls, the rule currently obligates 23 states to reduce emissions of nitrogen oxides from power plants and certain industrial facilities to limit their impact on downwind states. The ultimate timing of the effectiveness of the rule is uncertain, because several upwind affected states and sources have challenged the efficacy of EPA's proposed regulation in multiple courts, and stays of the effectiveness of the rule have been issued for many upwind states. In February of this year, oral arguments were presented to the Supreme Court by both sides, and we are closely monitoring the potential impact of the Supreme Court's ruling on whether to stay the rule for all states when it is issued later this year. In addition to the Good Neighbor Rule, we are also watching the progress of EPA's rule for large municipal waste combustor units, which is independent of the Good Neighbor Rule. This rule reduces the nitrogen oxide emissions requirements for large municipal waste combustor units. Fuel Tech has had a long history of assisting this industry in meeting its compliance requirements, and we have had discussions with customers in this segment to support them in their compliance planning. The municipal waste combustor rule is currently in a public comment period, with compliance deadlines expected sometime in the next three years. Lastly, within the past two weeks, EPA has issued new stringent greenhouse gas emission standards that require 90% reductions for most new gas-fired plants and existing coal units by 2032. This same proposed rule tightens the Mercury and Air Toxics Standards requirements by 2028, wastewater discharge limits for coal-fired power plants by 2029, and ash handling and disposal from coal-fired power plants over the next several years. This combined rule comes at a time when there are projections of potential shortfalls in power generation over the next five to seven years in certain geographic regions in this country, due to data center power demands and increases in computing power requirements resulting from the adoption of artificial intelligence. And we are in the process of evaluating the potential impact of these rules across our technologies in the power generation market. Now for the Fuel Chem segment. Revenues declined from the prior year Q1, due to a decrease in operational demand from our client base, resulting from warm weather across the US and, to a lesser extent, unscheduled plant outages and closures compared to the same period in 2023. As mentioned on our last conference call, we have been pursuing multiple additional Fuel Chem development opportunities, which could provide incremental revenue contribution in the H2 of 2024 for both coal and biomass-fired boilers. I'm very pleased to say that we have received an order for our Fuel Chem demonstration at a new coal-fired power generation site in the Western US The demonstration is expected to commence later this month, and if it becomes a commercial account, is expected to generate annualized revenue of approximately $1.5 million to 2 million at historic Fuel Chem, Fuel Chem gross margins. In addition to this domestic opportunity, we are in discussions with one additional coal-fired power generation facility regarding a demonstration later this year, also in the Western US, and we are also pursuing an opportunity to address the concerns of a biomass-fired boiler operator. With respect to international Fuel Chem opportunities, we remain in discussions with our partner in Mexico to expand the provision of our chemical technology in that country. We expect that the nation's upcoming presidential election in June will provide us with additional clarity on the likelihood of this opportunity, as the favored candidate is an environmental engineer by background and could take a favorable position on the implementation of environmental policy. We will provide more color on this opportunity on our next conference call. As we move into the H2 of 2024, we expect Fuel Chem revenue to improve due to the increased power demand and associated unit dispatch that comes during the summer months, and to contributions from the new coal-fired unit demonstration that will commence later this month. With our DGI initiative, our momentum continues. Last month, we executed an agreement to commence and complete a demonstration of DGI at a municipal wastewater site. In this instance, our DGI solution will be used to reduce hydrogen sulfide in the wastewater via oxygenation to reduce corrosion inside the wastewater lines. This application will demonstrate DGI's capability to extend the life cycle of aging infrastructure and eliminate the need for costly maintenance activities. Following the successful demonstration of our technology at a US shrimp farming facility last year...... We are in discussions with the owners of that same facility to incorporate DGI into their commercial scale planned stacked raceway system. The client is expecting to have their aquaculture system functional by the end of the year, and we are in the process of providing a proposal for a DGI system that will meet the precise needs of this aquaculture environment. Additionally, for aquaculture, we are in discussions with a potential new aquaculture client in the US that is considering incorporating DGI into a greenfield fish hatchery site in the western states. There are many other target markets of interest for DGI, including pulp and paper, food and beverage, chemical, petrochemical, and horticulture, and we look forward to addressing these markets prospectively. On the marketing front, we have been increasing our efforts to communicate the benefits of DGI to targeted end markets and customers, and we will be present at additional conferences later this year. Based on our effective backlog today, the business development activities we are pursuing, and our previously noted expectations for FUEL CHEM, we expect that total revenues for 2024 will exceed the total revenues recognized in 2023 of $27.1 million, and we will provide further guidance as we move throughout 2024. This base case outlook excludes any material contributions from DGI, as we are still in the early stages of commercialization. Any significant contributions to APC from the above-referenced EPA regulations and the impact of material business development activities for FUEL CHEM. In closing, I want to thank the Fuel Tech team for their continued contributions to our business. It is their hard work, passion, and dedication that drive our ability to be successful as a company. Additionally, I thank our shareholders for their continued support. We continue to expect that 2024 will be an important year in the growth and development and evolution of Fuel Tech, and we look forward to keeping you apprised of our progress. Now, I'd like to turn the call over to Ellen. Thank you, Vince, and good morning, everyone. For the quarter, consolidated revenues declined to $5 million from $7.3 million in last year's Q1, reflecting declines in both the APC and FUEL CHEM segments from the prior year period. APC segment revenue decreased to $2.3 million from $3.6 million in the Q1 of 2023, primarily related to customer-related delays and project execution. FUEL CHEM segment revenue declined to $2.6 million from $3.7 million in the Q1 of 2023, due to a decline in electrical generation demand and unscheduled plant outages. Consolidated gross margins for the Q1 were 41% of revenues, an increase from 38% in the Q1 of 2023, reflecting an increase in APC segment gross margin to 38% of segment revenues from 27% in the prior year period, due in large part to the mix of projects and services executed during the quarter. FUEL CHEM segment gross margin declined to 43% from 49% in the Q1 of 2023, as a direct result of lower segment revenue. We expect FUEL CHEM segment margins to return to historical levels as we continue throughout the year. Consolidated APC segment backlog on March 31st was $6.2 million, down from a backlog of $7.5 million at 31 December 2023. Backlog at 31 March 2024, included $1.8 million of domestically delivered project backlog and $4.4 million of foreign delivered project backlog, compared to $2.6 million of domestically delivered project backlog and $4.9 million of foreign delivered project backlog at December 31. We expect that $6 million of current consolidated backlog for the APC segment will be recognized in the next twelve months. SG&A expenses increased slightly to $3.3 million from $3.2 million in Q1 of 2023, reflecting higher employee-related expenditures. Given the decline in revenue, SG&A, as a percentage of revenue in the 2024 Q1, increased to 68% from 45% in the same prior year period. Research and development expenses for the Q1 rose to $376,000 from $218,000 in the same period a year ago, mainly reflecting our ongoing investment in the development of new technologies to expand our product offerings into the water and wastewater treatment markets, and more specifically, our DGI systems. Our operating loss was $1.7 million, compared to a loss of $658,000 in last year's Q1, reflecting a reduction in overall revenue, a shift in margin contribution from product mix, and slightly higher operating expenses for the quarter. We continue to take advantage of the favorable interest rate environment, and as of March 31st, have invested more than $30 million in held-to-maturity debt securities and money market funds. This generated $311,000 of interest income in the Q1, compared to $339,000 in the prior year period. Our net income for the quarter was $281,000, or $0.01 per share, compared to a net loss of $414,000, or a loss of $0.01 per share in the same period one year ago. Net income for the Q1 of 2024 included an extraordinary other income amount of $1.7 million, related to the recording of income associated with the expected receipt of the Employee Retention Credit during the quarter, as compared to an other expense of $90,000 in last year's Q1. For those of you not familiar with the employee retention credit, the CARES Act, established by the US government, was enacted to provide certain relief as a result of the COVID-19 pandemic. This tax relief, along with other stimulus measures, allowed for employers to claim a refundable tax credit against the employer's share of Social Security tax for qualifying periods in 2020 and 2021, subject to certain criteria. Under the provision of the CARES Act, the company was eligible for a refundable employee retention credit, which was claimed in Q1 of 2024. Adjusted EBITDA loss was $1.5 million, compared to an adjusted EBITDA loss of $569,000 in the same period last year. Lastly, moving to the balance sheet, our financial condition remains very strong. As of March 31, we had cash and cash equivalents of $11.4 million and short- and long-term investments totaling $20.7 million. Working capital was $27.7 million, or $0.90 per share. Stockholders' equity was $44 million, or $1.43 per share, and the company continues to have no outstanding debt. To reiterate Vince's earlier comments, we remain confident in our ability to fuel our growth initiatives, pursue new product and market opportunities, and maintain our strong financial position, which we view as an important competitive advantage, given ongoing macroeconomic uncertainties. We have a pipeline of significant growth opportunities across business segments that position us for positive growth in 2024. I'll now turn the call back over to Vince. Thanks very much, Ellen. I would like now to turn the call back to Operator for questions. Thank you. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. Our first question is from Amit Dayal with H.C. Wainwright. Please proceed. Thank you. Good morning, everyone. Good morning, Amit. Hey, hey, good morning. So with respect to, you know, I know weather-related issues, et cetera, you know, caused a little bit of weakness in 1Q, but overall, have you been adding new customers? It looks like in the FUEL CHEM segment, you may have added new customers. Just, Vince, maybe if you could give us some color on, you know, how that part of the business is holding up in terms of new customer additions, et cetera. Right. I would say, in terms of adding new customers, this year is really, in terms of those types of opportunities, we're seeing more of them this year than we have in a little while, which is great for us to see at this point in time. As I mentioned, as part of my script, we just signed an order for a demonstration that will literally be starting in about two weeks time. So we're encouraged about that opportunity. It's a large coal-fired unit in the Western US. We're in discussions with a second coal-fired unit, similar geographic location, coal-fired, as I said, and also a large unit, and that possibly could start sometime in Q3. And then on top of that, we, we've had some discussions with some owners of biomass-fired boiler units as well, that also could be new business opportunities. So I would say this year is really the first year in a while that we're seeing a larger scale of new business opportunity. We have not seen that in the past couple of years. So it's a new outlook for us. It's driven by pressures for those remaining coal-fired utilities to reduce their cost structure. It's driven by the need for some units to be available to run as support power for certain regions of the country and other drivers as well. So I'm very pleased that we're seeing the Fuel Chem opportunities come in our direction. They are very solid gross margin-generating business opportunities, and I would love to be able to see total revenue from Fuel Chem kick back up to it was four or five years ago. I'm not saying it's going to get there, but and any addition that we can bring on board right now, particularly in a coal-fired unit, is a nice benefit for us. So long answer to your question. I appreciate that, Vince. You also mentioned, you know, sort of the increase in electricity demand stemming from AI and data needs, et cetera, that is underway at a macro level. Yes. You have a balance sheet. You know, I know your immediate products may not directly cater to those opportunities, but are you thinking about, you know, any, acquisition opportunities that brings you closer to those types of opportunities going forward? Nothing that we're looking at right now, Amit. When we talk about some of those macroeconomic trends, it ultimately is supporting some of the, call it, lengthening of the life of the utilization of a lot of the coal-fired units. That in its own right is going to hopefully mean additional business for Fuel Tech in our current technology suite. So we're looking at that macroeconomic trend in a favorable light as we sit here today. But we aren't necessarily pursuing any acquisitions that would, you know, provide us the ability to address other needs, if you will, that are driven by additional power demand, whether it be AI or data centers and the like. Those trends are generally favorable for Fuel Tech, as are the trends in support of some additional environmental regulation. Understood. Thank you. Just last one for me. On the DGI side, it looks like you potentially could convert the pilot, right, shrimp farm into a customer. Like, how big should we think, you know, these order sizes can be when you deploy, you know, sort of a full system or a full-scale offering for these types of customers? To answer your question, yes, we are hopeful that we're able to go ahead and convert that demonstration, which was indeed successful, to a commercial sale. We're looking at putting the configuration together for a DGI system that will meet the needs of a commercial scale system for this shrimp farm owner, if you will. Right now, I probably see this as a capital sale, and I'm just going to give you a ballpark in terms of what this system would be offered at, and I'd say $500,000 to 1 million in terms of a capital sale of a DGI system, just to give you a ballpark range. Okay. And when these are deployed, Vince, do they also... Do you attach sort of maintenance type of, contracts or, you know, additional revenues? Yeah. To the extent we're able to build in support, after-market contracts, we will. I still think we have a little bit to learn relative to the deployment of these systems at sites and the ongoing necessary maintenance that's going to be required. We're not expecting that it's going to be extensive at customer sites once it's up and running. But to the extent that we can provide ongoing support on a quarterly basis or whatever is needed via contracts that support that activity, we'll definitely look to do so. Okay. So that's all I have, Vince. Thank you so much. Okay, Amit, thank you so much. As a reminder, it is star one on your telephone keypad if you would like to ask a question. Our next question is from Marc Silk, with Silk Investment Advisors. Please proceed. Hi, Vince. Thanks for taking my questions. Hi, Mark. No problem. How are you? I'm doing fine, thank you. On the APC delays, is that really basically because of the court issues, or this is just a regular delay? I would say more regular delays. Yeah, not necessarily related to court issues. Because with the business that we were expecting to pull into 2024, we really didn't factor in anything that was going to be regulatory-driven. That would be what I would call incremental business opportunity for us, and we'll know more about that a little bit later on this year. So I would call the delays just normal delays in both project execution and in coming to contract with certain potential customers. Okay. That's encouraging. And then, in your guidance, you're basically not putting in there any positive court rulings, correct? So that could be- That is correct. Surprisingly upside? Okay. Correct. Great. On the FUEL CHEM, that's actually exciting that it's coming to life a little bit. You know, you laid out really the reasons, but another one I want to know is, is it because also there's not many other competitors anymore, but just because it's not a growing industry? Actually, for this particular technology application market, there really aren't any competitors for what we do specifically with FUEL CHEM. But it requires a specific customer need for us to be utilized and our program is not inexpensive. But if we offer a client the ability to keep their units running during high-demand times, and by perhaps using a lesser quality coal or a difficult-to-burn coal, they recover the cost of our program very, very quickly. So no one else does what we do with this technology, but the very specific need isn't necessarily out there at all coal-fired units. Okay, that's great. And then, the... I'm intrigued by this municipal wastewater site. Can you talk more of this? Like, what are they looking for? What are you bringing to the table? That's the first question, and then we'll go from there. Yeah. So the site we're looking to demonstrate at is, it's again, it's a municipal plant. And in certain stages of the treatment process, there are areas whereby the wastewater becomes less than oxygenated, or it has less oxygen than it needs to go ahead and maintain what I would call good quality water. And when in this part of the application, when it doesn't have the oxygen it needs, it actually creates hydrogen sulfide, and over time, hydrogen sulfide is going to erode the insides of those lines. So the application we're working on is specifically attempting to keep these feed lines, as part of the wastewater treatment plant, oxygenated at specific levels whereby they don't create any detrimental effects to that piping system. ... So how do they find you, by the way? How do these guys find us? That's a good question. Actually, these folks were a contact of Bill Decker. Bill is the gentleman we hired last year to help us support the development of DGI. So these folks that we're working with are well-established in the water and wastewater treatment industry, and hopefully, they will turn out to be a good partner of Fuel Tech prospectively. So the interesting thing is, you know, with municipalities versus private industry, it's not a competitive, let's say, competition, right? So are you able to kind of work with them and say, "Listen, we want other municipalities to watch this," so it's more of an open trial, just 'cause it's gonna benefit really any water, I mean, so any municipality in the country? Yeah, we're really taking this step by step, right? But what we need is a first success, and once we have the first success, then we'll be able to work with that documented, science-based, data-driven result. And then we can expand on that documentation, if you will, with other municipalities. So I think we need to take the first step here and ensure we have a successful demonstration, and then we move forward from there. Okay. And then I know last call, someone was asking about insider buying. So, hopefully, it sounds like, you, you're getting your ducks lined up, so hopefully we see some more insider buying. And, good luck going forward. Okay, Mark. Thank you very much. We have reached the end of our question-and-answer session. I would like to turn the call back over to Mr. Arnone for closing comments. Thank you, operator. I'd like to thank everyone that joined the call today. I'd like to thank the entirety of the Fuel Tech team for their support on Fuel Tech's activities, and as usual, thank all of our stakeholders, shareholders for their continued support of Fuel Tech. Everyone, have a great day, and we'll talk to you again soon. Thank you. Thank you. This will conclude today's conference. You may disconnect your lines at this time, and thank you for your participation.
