Thank you, Devin. Good morning, and I'd like to thank everyone for joining us on the call today. On our March conference call, we expressed encouragement with our near-term outlook for business development opportunities. I'm pleased to report that our first quarter contract booking activity met our expectations, with $5.6 million in bookings announced to date, and we had the best first quarter performance for our FUEL CHEM business segment in more than ten years. We believe that 2025 will be a year of growth for our company. Revenues for the first quarter of 2025 rose 29% from the prior year period, primarily driven by the aforementioned robust performance from our FUEL CHEM business segment. For the quarter versus the prior year, we expanded our gross margins, narrowed our operating loss and significantly increased our APC project backlog to the highest level in three years. Further, we maintained a strong financial position with cash, cash equivalents and investments of approximately $31 million at quarter end and no long-term debt. On an overall basis, we are encouraged by the global landscape of business development activities that we are seeing, driven by continued expansion in manufacturing in many sectors and by the growing demand for power generation as a whole, which is being driven by several reasons, most notably the advancement of artificial intelligence. Fuel Tech's portfolio of emissions control solutions has proven to be an integral part of infrastructure buildouts in the US and around the world. Regardless of fuel source, our technologies are used to reduce harmful gases, including nitrogen oxides and sulfur trioxide as well as particulate emissions from combustion sources while enhancing operating efficiencies and allowing industrial and utility customers to remain compliant with state, federal and country-specific regulations. Investment in water quality and water infrastructure is also growing, and we believe that our Dissolved Gas Infusion technology offers a compelling solution for municipal and industrial end markets. We have a product demonstration that will commence later this month and are in discussions with customers representing multiple end markets that can benefit from our water technology. Now let's talk about our results for the quarter. Our FUEL CHEM business segment began 2025 with the best first quarter performance that we have seen in ten years, with revenues rising 92% compared to last year's first quarter. This was the result of the return to full operation of our base accounts and the incremental contribution from the new commercial account that we added in the second quarter of 2024. We continue to pursue additional FUEL CHEM opportunities, both domestically and internationally and we currently expect that a new demonstration of our TIFI Targeted In-Furnace Injection technology is likely to commence late in the third quarter of this year at a coal-fired unit in the Midwest. 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. Based on conversations with our partners in Mexico, it is still our understanding that the newly elected government is targeting the implementation of environmental policy aimed at the reduction of pollutants that cause climate change. As Mexico plans to use the heavy fuel oil generated from their oil refining operations as fuel for power generation for the near term future, we are hopeful that our FUEL CHEM program will be an integral part of President Sheinbaum's plan. Now let's turn to our APC business segment. APC revenues declined from last year's first quarter due primarily to the timing of project execution. However, we have been encouraged by the cadence of new contract awards and are currently addressing the best portfolio of APC business opportunities that we have seen in several years, both domestically and internationally. We generated $5.6 million in APC orders during the first quarter, which drove a 66% increase in our backlog at March 31st, 2025, from December 31st, 2024. We are continuing to pursue additional new awards, driven by industrial expansion globally and by state-specific regulatory requirements in the US and we are also following incremental opportunities for the municipal solid waste or MSW market that have a good probability of coming our way later this year. As of today, we currently expect to close an additional $3 million to $5 million in new contract awards by the end of the current second quarter. As mentioned previously, the artificial intelligence boom has generated increasing demand for datacenters. This growth will require a significant increase in energy over the next several years. To address the necessary emissions control requirements of these facilities, we are utilizing our SCR and ULTRA technologies to participate in larger domestic contract opportunities. We are working with multiple parties involved in the development of datacenters and have submitted budgetary bids in pursuit of opportunities in this market. Regarding the regulatory front, as we mentioned on our conference call in March, we are not expecting any specific tailwinds that would come from the implementation of new regulations as the new administration is not likely to implement regulations that we're working through the process of approval and finalization when the new term commenced. It is important to note that the opportunities that we are following today are not contingent on the implementation of any new regulations. We are continuing to monitor progress of the EPA's rule for the large municipal waste combustor units, which is independent of the Good Neighbor Rule. This rule reduces the nitrogen oxide emissions requirements for large MWC units. Fuel Tech has had a long history of assisting this industry in meeting its compliance requirements and we've had discussions with customers in this segment to support their compliance planning. The final rule has been delayed by EPA until December of 2025 with compliance deadlines expected three years from the date of issue. That being said, there are some specific states that are currently requiring lower NOx emissions that are consistent with the proposed MWC rule and we are actively pursuing those opportunities today. For DGI, we have deployed our equipment to the site of a fish hatchery in the Western US and our demonstration, which is expected to last nine to 12 months, will commence before the end of this month. This demonstration will have defined test protocols to evaluate the benefits of the DGI technology, resulting from the supply of consistent and precise levels of dissolved oxygen and the raising of game fish in a controlled environment. In addition to this demonstration, discussions are progressing with a municipal wastewater treatment facility in the Southeastern United States and we are pursuing other end markets of interest for DGI, including pulp and paper, food and beverage, chemical and petrochemical, and horticulture. We continue to receive inquiries regarding DGI from potential customers in multiple end markets and are hopeful that we can generate our first commercial revenues in 2025. Additionally, we have recently executed sales representative agreements with two companies that will focus their efforts on helping us to bring DGI into end markets and we expect to add additional representatives imminently. Based on our effective backlog, recent contract awards, the APC business development activities that we are pursuing, and our previously noted expectations for FUEL CHEM, we are maintaining our revenue guidance for 2025. We continue to expect that total revenues for 2025 will approximate $30 million, with both business segments exceeding their performance in 2024. This base case outlook excludes any material revenue contributions from DGI, any significant contributions to APC from new regulations or from large datacenter contract awards, and any impact from new material business development activities for FUEL CHEM. In closing, we are very encouraged by the recent developments at APC, the continued growth potential from our FUEL CHEM segment, and the opportunities we are pursuing at DGI. I want to express my thanks to the Fuel Tech team for their continued efforts in support of our strategic goals, and I want to thank our shareholders for their continuing interest in and support of our company. I also want to let everyone know that we will be presenting at the upcoming Sidoti Micro-Cap Virtual Conference, which is being held on May 21st and 22nd. I invite everyone to listen to our presentation. We will notify everyone of our specific presentation day and time via press release within these next couple of business days. Now, I'd like to turn the call over to Ellen for her comments on our financial results. Ellen, please go ahead.

Thank you, Vince, and good morning, everyone. For the quarter, consolidated revenues rose 29% to $6.4 million from $5 million in last year's first quarter, reflecting significant growth in our FUEL CHEM segment revenue, partially offset by a decrease in APC segment revenue compared to the prior year period. FUEL CHEM segment revenue increased by 92% to $5.1 million from $2.6 million in the prior year period and comprised nearly 80% of total revenues for the quarter. This was driven by customer accounts returning to service as a result of outage completions, increased dispatch and sustained contributions from the new coal-fired account added in 2024. Conversely, APC segment revenue declined to $1.3 million from $2.3 million in last year's first quarter, primarily related to timing of project execution on existing contracts. Consolidated gross margin for the first quarter rose to 46% of revenues from 41% in last year's first quarter. This improvement reflected the higher proportion of FUEL CHEM segment revenue during the quarter, which returned to historical margins of 50% from 43% in Q1 of 2024, partially offset by a decline in APC margins to 33% of segment revenues from 38% in the prior year period. The decline in APC gross margin was driven by changes in product and project mix. As a reminder, the APC segment contains revenues from capital projects and ancillary revenues for items such as post contractual parts and services. Ancillary point-in-time revenues maintain a higher margin profile and will offset fluctuating project revenue margins, which are recognized over time based on project completion. The duration of APC project completion typically ranges from 8 to 24 months with engineering and production costs dependent on design approval and delivery schedules, which directly impact timing of revenue recognition. As expected, APC backlog improved significantly in early 2025 due to the success of business development activities. Consolidated APC segment backlog on March 31st, 2025, was $10.3 million, up from a backlog of $6.2 million at December 31st, 2024. Backlog at March 31st, 2025 included $3.6 million of domestically delivered project backlog and $6.7 million of foreign delivered project backlog compared to $1.9 million of domestic delivered project backlog and $4.3 million of foreign delivered project backlog at December 31st. We expect that approximately $6.9 million of current consolidated backlog will be recognized in the next 12 months. SG&A expenses were flat at $3.3 million for the first quarters of 2025 and 2024. As a percentage of revenue, SG&A expenses declined to 52% in Q1 of 2025 from 67% in Q1 of 2024, reflecting the increase in revenue. For 2025, we expect SG&A expenses to increase modestly from the prior year. Research and development expenses for the first quarter increased to $570,000 from $376,000 in last year's first quarter due in large part to our continuing investment in water and wastewater treatment technologies, specifically our DGI systems. Our investment in DGI will continue throughout 2025 along with expenditures to support our growth initiatives. Our operating loss was $952,000 compared to an operating loss of $1.7 million in last year's first quarter, reflecting the increase in consolidated revenue and improved gross profit. We continue to take advantage of the favorable interest rate environment and as of March 31st, 2025 had invested a large portion of our $30 million in held-to-maturity debt securities and money market funds. This generated $279,000 of interest income in Q1 of 2025. Our net loss for the quarter was $739,000 or $0.02 per share compared to net income of $281,000 or $0.01 per share in the same period one year ago. The difference in net income from the prior year was mainly due to a one-time other income amount of $1.7 million in last year's first quarter associated with the receipt of the ERC, the employee retention credit under the CARES Act. Excluding this one-time other item, net loss for Q1 2024 was $1.4 million or $0.05 per share. Adjusted EBITDA loss narrowed to $735,000 compared to an adjusted EBITDA loss of $1.5 million in the same period a year ago. Lastly, moving to the balance sheet. Our financial condition remains very strong. As of March 31st, 2025, we had cash and cash equivalents of $11.8 million and short and long-term investments of $19.3 million for a total of $31.2 million. Shares outstanding at quarter end were approximately 30.8 million, resulting in cash per share of $1.01. Working capital was $24.9 million or $0.81 per share. Stockholders' equity was $41.4 million or $1.35 per share and the company continues to have no outstanding debt. We remain greatly confident in our ability to maintain a strong financial position and to fund our short and long-term growth initiatives. Now I'll turn the call back over to Vince.

Thanks very much, Ellen. Operator, let's please go ahead and open up the line for questions.

Thank you. Our first question comes from Amit Dayal with H.C. Wainwright. Please proceed with your question.

Thank you. Good morning, everyone.

Good morning, Amit.

It looks like the business is in a pretty strong position relative to last year. Any color to think about the current political environment and it doesn't look like it's slowing down things for you too much. Just any update on how you are positioned to deal with some of these uncertainties in the market right now with respect to all sorts of these regulations that are potentially being implemented?

Yes. At this point in time, Amit, I think I would say we're not completely sheltered, obviously, from what's going on in the marketplace today in general. But I will say that what's happening with the new administration at this point in time is not deterring us from capturing opportunities that we would normally look to capture historically, right? We did not have any preconceived ideas that there were going to be new regulations put in place environmentally that would give us a boost. That would have been our expectation perhaps last year. That's not the case today. But the general business expansion and some of the needs that are driving the growth of power generation, they are definitely market drivers for our businesses. So, from that perspective, we find ourselves in a pretty good position as we hear today. Now, one more comment I'll make is that we have been seeing over these past two to three years, because of the requirement for increased power generation, we've seen some extension of the life of coal-fired units. And that could continue to bode well for us because I think we're going to see more extensions of the life of coal-fired units given just a general demand for very reliable power that we have in this country and other parts of the world. So on an overall basis, there are probably some puts and takes, but I'm pleased with where we sit today, and I'm not seeing any decrement in business activity with some of the uncertainties in the marketplace, at least as of today.

Understood. Thank you for that. And then with respect to the datacenter opportunity, any names you can share, who you may be partnering with to make inroads with this developing market. The reason I'm asking is if there are names that the Street is sort of aware of that are already active. Just trying to get a sense of if you get designed into any of these deployments and does that help you scale the opportunity faster?

Yes. So to your first question, I really can't name a specific name, but what I'll tell you is that we're working with OEM suppliers of gas turbines and engines. We're also working in support of datacenters that are being built out by some of the largest tech companies in the marketplace. So without saying specific names, we are working with that group of entities, if you will. And then secondarily, what we have been doing is, as we've been watching this evolve, is looking to come up with specific designs for specific power generating turbines or engines that we would indeed look to scale, because in most cases, the sites that we're looking at are going to be multiples of units and not just one-off units for a gas turbine or engine. It may be five, it may be ten, it may be twenty, it may be more. And so to the extent that we can get close to finalizing those designs and be ready to go once we have the opportunity coming our way, that just bodes well for Fuel Tech and enables us to work in a proactive way with our supply chain as well.

Understood. How big is that pipeline? Any color on is it still early to maybe give any numbers? But just curious how big that opportunity is for you right now?

Yes. The numbers can get pretty large, Amit. I mean, if you're talking a multiple of 20 units and if you're to call it the one unit cost could be in the $1 million to $2 million range, you can do the math from there. So the opportunities can get to start to become pretty large in nature, which is why we are excited. And again, we're very, very hopeful that we'll see one or more of these contract awards hopefully come our way as we move towards the remainder of 2025. There's a lot of activity and there's a lot of parties involved as well. So we're trying to well position ourselves with those folks that we think are going to be solid, reliable players in those markets.

Understood. Just last one from me with respect to the Mexico opportunity. Is there any particular catalyst or some kind of funding that needs to become available for that opportunity for you to potentially begin receiving orders, etc.?

Yes. What really needs to happen, Amit, is the Mexican government needs to allow funds to be spent on systems like ours to go ahead and start remediation of some of their pollution issues. It's become really serious around some of their major cities. You see it in the news quite often down there. And we're just hoping at some point in time and again, given the platform that was run on by the President, we are hoping that their environmental needs will become a little more top of mind not too far into the future here.

Understood. Thank you, Vince. That's all I had.

You're welcome. Thank you.

Thank you. Our next question comes from Marc Silk with Silk Investment Advisors. Please go ahead with your question.

Hey, Vince. Thanks for taking my questions.

My pleasure, Mark. How are you?

I'm doing well. Thanks.

Good.

So the datacenter opportunity, obviously, with this administration, there's no urgency for them to do things environmentally friendly. But the conversations you have, are they thinking beyond this administration and that's kind of why you feel it's an opportunity?

Yes. So what we're seeing with some of the datacenter opportunities that we are looking to address is, in some cases, the power generation is primary power. In some cases, it's backup power. If it's primary power, it's undercurrent environmental regulations, those units are going to require pollution control technology as baseload generation. If it's backup power, it gets to be a little bit more specific in nature in terms of the expectation for how long or how many hours a year those backup units will be asked to run. So in some cases, backup power may not require pollution control technologies. In other cases, it will. So again, as I said as part of my script, the opportunities that we're looking at today aren't necessarily driven by any new regulations, but they're also making the assumption that what's in place today as EPA regulations stay in place and it's not going to be removed completely.

Okay. And then switching gears to the DGI. So you're hiring other entities to help you sell this. Can you kind of give us a little color on that and what they've kind of laid out for you as far as their potential and promises?

Yes. So it was always our expectation when we look to address additional market channels for DGI that we would need some expertise in order to obtain access to those channels. And as Fuel Tech, historically, we have worked with manufacturing representatives for both our APC business and for our FUEL CHEM business as well. So for water, we are actually doing the same thing. We needed to come to a point whereby we were able to speak with confidence with some of these companies. So they felt as though they were representing a technology and investing their time and effort in looking to put a good technology into end markets. So it's taken us a while to get to that point. But as I mentioned in my script, we signed up two already. That just happened recently. And they're for different end markets and geographies. But we're likely to look to put in place several more as well, again, to help us get product into end markets.

And then last question. You recently went to a show for the DGI. Can you give us any color on what people are saying about your product and its potential for growth in that area?

Yes. So we went to the Aquaculture America show, and it was extremely well received. We obtained multiple leads for opportunities again in the aquaculture marketplace. There's one specific lead that we issued a proposal for here within this past week and a half. So the technology was well received. We were perceived as being innovative for that particular end marketplace and we need to find those folks that are willing to take a chance at working with a new innovation for meeting that market application's need for oxygenation. But the DGI was very well received.

Great. Good start to the year and continued success.

Thank you very much, Mark. I appreciate it.

Thank you. Our next question comes from the line of William Bremer with Vanquish Capital Partners. Please proceed with your question.

Good morning, Vince.

Hey, good morning, Bill. How are you?

Good, good. Thank you. Outside of coal, can you give us an update on your exposure to possibly natural gas developments?

From what perspective when you say natural gas developments?

Given the build-out and the supply of gas for electrical generation needs via datacenters, etc. Outside of the datacenter market and the facilities, where do we have content?

Yes. Today, we would find opportunities for natural gas-based systems with manufacturing expansion, projects that we've been doing for certain end markets and industries that end up using natural gas as their choice of fuel. But that would be the primary other avenue that we'd be focusing on for utilization of natural gas.

Right. I knew we had exposure there. Just for the update.

And we do have just one more comment to make. We do have some exposure for natural gas applications for utility units as well, not necessarily for this country, but for other countries as it relates to some of our technologies.

Right. Thank you for the refresher on that.

You're welcome.

And given the datacenter opportunities, and I know this is a difficult question to answer, but can you provide a range that if we're successful, what's the low end? What's the, I mean, we're talking multiple millions here per datacenter content. Isn't that correct?

That is correct. As I just mentioned regarding one of the other questions, we're looking at on a per-unit basis, it could be $1 million to $2 million per unit. And again, we're talking multiples of units at a site. So, yes, the numbers get very large.

All right. And the fact that your fabs lift, I'm assuming that's an advantage to you in terms of the production and the timing to get the systems there. I'm hoping that you're making that known to your potential entities when you're bidding for these.

Yes. As part of our discussions with the companies that we're working with, we have a heavy focus on how we manage the supply chain as part of the execution process, how we manage the risk for some of the other market forces that are in place today, whether it be tariff-oriented or otherwise, and how do we control those risks as we look to work through a project execution cycle, particularly something that could be of a larger magnitude. So those are discussions that we are having and we're prepared to have with others.

Okay. Now onto DGI. Looking forward to some consummation here for sure, and this is just a comment. I would welcome hearing Bill Decker who's heading this program alongside yourself maybe on a future call just to give us more of a granular update on what he's seeing and the technology. I think it would be a beneficial sharing of information to all the shareholders.

Okay. Point noted, Bill. Thank you very much.

And finally, we're trading below cash per share. At what point given your visibility and confidence do you realize, and the Board seems to feel that a stock buyback at this level is probably the best return of capital for the shareholders as well as the company?

We actually just recently had a discussion at our most recent Board Meeting here earlier this month. It's something that we talk about on a recurring basis. As we sit here today, Bill, we believe we have enough potential positive momentum to be a driver for the stock price that, that would be the better outcome than using our precious cash balance at this point in time to enable the same thing. That's our thought process today, not necessarily saying that it would stay that way in the future, but that is our thought process today.

Okay. Thank you very much.

Thank you, Bill.

Thank you. Ladies and gentlemen, there are no further questions at this time. I'll turn the floor back to Mr. Arnone for any final comments.

Thank you, operator. Thanks, everyone for joining today. Thanks for your patience with my speaking voice. I have a little bit of a cold this morning. If you have the opportunity to listen to the Sidoti Micro-Cap Virtual Conference, please join us for my presentation. You're welcome. And then just want to thank, again, the Fuel Tech team for all of their support and all of the hard work they do day in, day out in support of our company. And again, thanks to our shareholder base as well. We're doing everything that we can to look to deliver favorable shareholder value. Thanks, everyone, and have a good day.

Thank you. Ladies and gentlemen, this concludes today's conference call. You may disconnect your lines at this time. Thank you for your participation.
