Speaker #4: Thank you, Devin. Good morning, and I'd like to thank everyone for joining us on the call today. 2025 was a year of multiple achievements for Fuel Tech.

Vince Arnone: Thank you, Devin. Good morning, I'd like to thank everyone for joining us on the call today. 2025 was a year of multiple achievements for Fuel Tech, marked by an expanded opportunity sets in our Air Pollution Control business segment, driven largely by anticipated growth in data center development and construction. A resurgence in revenue for our FUEL CHEM operations, where revenues for the year exceeded our expectations and reached their highest levels since 2018, and tangible progress at our Dissolved Gas Infusion business. We maintained a strong financial position with cash equivalents, and investments of nearly $32 million at year-end and no debt. Our FUEL CHEM segment ended an already strong year on a high note.

Speaker #4: We maintained a strong financial position with cash, cash equivalents, and investments of nearly $32 million at year-end, and no debt. Our Fuel Chem segment ended an already strong year on a high note.

Speaker #4: Across the country, the useful life of coal-fired units is being extended to satisfy growing energy demand, and many of these units were dispatched at levels that haven't been realized in several years.

Vince Arnone: Across the country, the useful life of coal-fired units is being extended to satisfy growing energy demand, and many of these units were dispatched at levels that haven't been realized in several years. Our results for the FUEL CHEM segment benefited from this phenomenon, in particular for our legacy units.

Speaker #4: Our results for the Fuel Chem segment benefited from this phenomenon, in particular for our legacy units. In addition, 2025 results were favorably impacted by the full-year performance of a U.S. commercial unit that we added late in 2024, and from a new U.S. customer that is currently operating with us under a six-month, commercially priced demonstration program that commenced in early November of 2025.

Vince Arnone: 2025 results were favorably impacted by the full year performance of a US commercial unit that we added late in 2024, and from a new US customer that is currently operating with us under a six-month commercially priced demonstration program that commenced in early November of 2025. As we have discussed previously, the annual revenue potential from this commercial opportunity, should it convert from a demonstration, is expected to be approximately two and a half to $3 million based on the customer running the program full-time, with the revenue expected to generate historic FUEL CHEM gross margins. I want to share a bit of additional color regarding our FUEL CHEM de-demonstration program.

Speaker #4: As we have discussed previously, the annual revenue potential from this commercial opportunity should have converted from a demonstration is expected to be approximately $2.5 to $3 million, based on the customer running the program full-time, with the revenue expected to generate historic fuel chem gross margins.

Vince Arnone: with the revenue expected to generate historic FUEL CHEM gross margins. I want to share a bit of additional color regarding our FUEL CHEM de-demonstration program.

Speaker #4: I want to share a bit of additional color regarding our fuel chem demonstration program. This customer was interested in our program as a means to improve boiler availability and reliability.

Vince Arnone: This customer was interested in our program as a means to improve boiler availability and reliability, and to reduce maintenance downtime for offline boiler cleaning, in particular, during periods of high power generation demand. This customer utilizes a source of coal that is high in sodium content and is prone to extensive slagging and fouling. To date, the customer has realized a material reduction in downtime and maintenance costs due to a reduction in offline cleaning, which bodes well for a successful demonstration. Revenues generated by our APC segment rose in Q4, declined annually, reflecting customer-driven delays and project award timing. We secured $8.8 million of APC awards during 2025 from new and existing customers in the US, Europe, and Southeast Asia. Our near-term sales pipeline of APC contracts, exclusive of data center opportunities, is between $3 million and $5 million.

Our near-term sales pipeline of APC contracts, exclusive of data center opportunities, is between $3 million and $5 million.

Speaker #4: Revenues generated by our APC segment rose in the fourth quarter, but declined annually, reflecting customer-driven delays and project award timing. We secured $8.8 million of APC awards during 2025, from new and existing customers in the US, Europe, and Southeast Asia.

Speaker #4: Our near-term sales pipeline of APC contracts, exclusive of data center opportunities, is between $3 million and $5 million. While we had hoped to close on these opportunities by year-end, discussions remain active and we expect to close before the end of the current second quarter.

Vince Arnone: While we had hoped to close on these opportunities by year-end, discussions remain active. We expect to close before the end of the current Q2. Even with these delays, we ended the year with a consolidated APC segment backlog of $7 million, up from $6.2 million at the end of 2024. As we announced Q1, we expanded our APC portfolio through a small strategic acquisition of complementary intellectual property and customer-related assets from Wahlco Inc, a well-established environmental equipment and services company with several hundred project installations worldwide. As we continue to integrate Wahlco's operations, we have been encouraged by the pace of project inquiries from their client base and others, including a number of near-term needs.

Speaker #4: Even with these delays, we ended the year with a consolidated APC segment backlog of $7 million, up from $6.2 million at the end of 2024.

Speaker #4: As we announced last quarter, we expanded our APC portfolio through a small strategic acquisition of intellectual property and customer-related assets from Walco, Inc., a well-established environmental equipment and services company with several hundred project installations worldwide.

Vince Arnone: As we continue to integrate Wahlco's operations, we have been encouraged by the pace of project inquiries from their client base and others, including a number of near-term needs.

Speaker #4: As we continue to integrate Walco's operations, we have encouraged by the pace of project inquiries from their client base and others including a number of near-term needs.

Vince Arnone: The value proposition for us in acquiring Wahlco was in securing these high-value assets at a modest price, strengthening our technology portfolio, and attracting a broader base of potential customers. This proposition seems to be playing out thus far. With respect to the data center opportunity, these facilities will potentially require emissions control solutions to mitigate their environmental footprint, comply with federal, state, and local regulations, and align with corporate sustainability mandates. Our sales pipeline for these opportunities remains strong and approximates $75 to $100 million for projects integrating our SCR technology with power generation sources. Please note that the value of the pollution control scope of supply represents a very small fraction of the estimated total AI infrastructure spend. I want to provide a little more information about our data center opportunity.

Speaker #4: Our sales pipeline for these opportunities remains strong and approximates $75 million to $100 million per project integrating our SCR technology with power generation sources. Please note that the value of the pollution control scope of supply represents a very small fraction of the estimated total AI infrastructure spend.

Speaker #4: I want to provide a little more information about our data center opportunity. First, I think that we have been clear that any material near-term growth for our company will likely derive from our success in addressing this opportunity.

Vince Arnone: First, I think that we have been clear that any material near-term growth for our company will likely derive from our success in addressing this opportunity. As such, we have been and continue to devote substantial internal and external resources to position Fuel Tech with data center developers and turbine and engine providers to deliver NOx reduction technologies as part of a data center's power generation platform. One point that I want to highlight is that Fuel Tech is a subcontractor in the data center ecosystem. In all instances, we are a subcontractor to the data center integrator or to the turbine or engine OEM. This relationship limits our knowledge of the development of the data center opportunity, its funding, its phase of approval, and its timing.

Speaker #4: This relationship limits our knowledge of the development of the data center opportunity, its funding, its phase of approval, and its timing. Our role remains the support and education of our direct customer regarding the design and delivery of a pollution control system that can best fit the application.

Vince Arnone: Our role remains the support and education of our direct customer regarding the design and delivery of a pollution control system that can best fit the application. It does not dilute the opportunity landscape or temper our enthusiasm in any way. It does make providing specific insights with respect to the timing of awards more challenging. This is what we can currently share about the opportunity. At present, we are in various stages of participation in project opportunities with more than 10 different data center integrators and turbine and engine OEMs, including some of the largest companies in the industry. All of these inquiries are for pollution control systems, primarily SCR, in support of the development of on-site power generation.

Speaker #4: This does not dilute the opportunity landscape or temper our enthusiasm in any way. But it does make providing specific insights with respect to the timing of awards more challenging.

Speaker #4: This is what we can currently share about the opportunity. At present, we are in various stages of participation in project opportunities with more than 10 different data center integrators and turbine and engine OEMs.

Speaker #4: Including some of the largest companies in the industry. All of these inquiries are for pollution control systems, primarily SCR, in support of the development of onsite power generation.

Vince Arnone: All of these inquiries are for pollution control systems, primarily SCR, in support of the development of on-site power generation.

Vince Arnone: The size of these projects run the gamut from as little as 2 to 5 units per project to as many as 30 to 40 NOx reduction units, with pricing predominantly in the range of $1 million to $2.5 million per unit. Regarding timing, the earliest we expect any of these inquiries to convert to a commercial award based on our conversations with the various parties involved is Q2 2026, as the schedule requirements for at least 2 of the projects would necessitate the receipt of an award by then. The remainder of the inquiries will develop further as we move throughout the year. To the best of our knowledge, with just 1 exemption, none of the inquiries that we are currently involved with have been awarded.

Speaker #4: The size of these projects run the gamut, from as little as two to five units per project, to as many as 30 to 40 NOx reduction units with pricing predominantly in the range of $1 million to $2.5 million, per unit.

Vince Arnone: To the best of our knowledge, with just 1 exemption, none of the inquiries that we are currently involved with have been awarded.

Vince Arnone: More specifically, we are still very much in the running to capture our share of these opportunities, and we remain optimistic about our prospects for 2026. On the regulatory front, we have seen that the current administration is currently pursuing both the rollback of specific regulations that had been put in place previously and the implementation of new regulations that are less restrictive than those currently in place. Regarding the rollback of regulations, EPA announced the rescission of rules related to the reduction of greenhouse gases. Regulation of these emissions started in 2009 with the EPA Endangerment Finding based on a 2007 Supreme Court ruling. EPA has also announced the repeal of the 2024 Mercury and Air Toxics Standards for coal-fired units.

Speaker #4: More specifically, we are still very much in the running for opportunities, and we remain optimistic about our prospects for 2026. On the regulatory front, we have seen that the current administration is pursuing both the rollback of specific regulations that had been put in place previously, and the implementation of new regulations that are less restrictive than those currently in place.

Speaker #4: Regarding the rollback of regulations, EPA announced the rescission of rules related to the reduction of greenhouse gases. Regulation of these emissions started in 2009 with the EPA endangerment finding based on a 2007 Supreme Court ruling.

Vince Arnone: Regulation of these emissions started in 2009 with the EPA Endangerment Finding based on a 2007 Supreme Court ruling. EPA has also announced the repeal of the 2024 Mercury and Air Toxics Standards for coal-fired units.

Speaker #4: EPA has also announced the repeal of the 2024 Mercury and Air Toxic Standards for coal-fired units. It is important to note that both of these proposed rollbacks do not loosen the nitrogen oxide emissions reduction requirements for any sources, and could potentially extend the life of some coal and natural gas-fired units that may not have to reduce their emissions profile.

Vince Arnone: It is important to note that both of these proposed rollbacks do not loosen the nitrogen oxide emissions reduction requirements for any sources and could potentially extend the life of some coal and natural gas-fired units that may not have to reduce their emissions profile. We will take the opportunity where applicable, to offer retrofit and maintenance solutions to accommodate the extensions of useful life. Now regarding the implementation of new rules. Earlier this year, EPA issued New Source Performance Standards, also known as NSPS, for new gas turbines, which were published in the Federal Register on 15 January. The NSPS was required for EPA consent decree with Sierra Club and the Environmental Defense Fund, were in response to the proposed rules that were issued in November 2024.

Speaker #4: We will take the opportunity where applicable to offer retrofit and maintenance solutions to accommodate the extensions of useful life. Now, regarding the implementation of new rules, earlier this year, EPA issued new source performance standards also known as NSPS for new gas turbines which were published in the Federal Register on January 15th.

Vince Arnone: for new gas turbines, which were published in the Federal Register on 15 January. The NSPS was required for EPA consent decree with Sierra Club and the Environmental Defense Fund, were in response to the proposed rules that were issued in November 2024.

Speaker #4: The NSPS was required for EPA consent decree with Sierra Club and the Environmental Defense Fund, and were in response to the proposed rules that were issued in November 2024.

Vince Arnone: A new category of gas turbines was created called temporary power turbines, and is applicable to units below 85 MW installed to run for 24 months or less. These units will be required to achieve NOx levels of 25 PPM, which in some cases may not require SCR for all turbines. Turbines greater than 5 MW with high operating capacity will need to meet 15 PPM of NOx, which will likely require SCR, and turbines greater than 85 MW will need to get to 5 PPM NOx, which will require SCR in almost all cases. What is the impact of the new regulation?

Speaker #4: A new category of gas turbines was created, called temporary power turbines, and it's applicable to units below 85 megawatts installed to run for 24 months or less.

Speaker #4: These units will be required to achieve NOx levels of 25 ppm, which in some cases may not require SCR for all turbines. Turbines greater than 5 megawatts with high operating capacity will need to meet 15 ppm of NOx, which will likely require SCR, and turbines greater than 85 megawatts will need to get to 5 ppm NOx, which will require SCR in almost all cases.

Speaker #4: So what is the impact of the new regulation? First of all, several organizations, including the Clean Air Task Force, Sierra Club, the Environmental Defense Fund, have filed a petition for reconsideration with the EPA.

Vince Arnone: First of all, several organizations, including the Clean Air Task Force, Sierra Club, the Environmental Defense Fund, have filed a petition for reconsideration with the EPA. The hard deadline to file a formal lawsuit challenging these amendments in the US Court of Appeals for the DC Circuit is 16 March of this year. It is certain that lawsuits will be filed. Second, with this rule in place, power generation developers will need to decide how best to proceed with their pollution control solutions for their new sources of power generation. Based on this, the discussions that we have had with our potential client base, we are not aware of this new regulation having a significant negative impact on decision-making regarding the implementation of pollution controls. It is important to note that state-specific permitting requirements can vary from the new federal regulation.

Speaker #4: And the hard deadline to file a formal lawsuit challenging these amendments in the US Court of Appeals for the DC Circuit is March 16th of this year.

Speaker #4: It is certain that lawsuits will be filed. And second, with this rule in place, power generation developers will need to decide how best to proceed with their pollution control solutions for their new sources of power generation.

Vince Arnone: Based on this, the discussions that we have had with our potential client base, we are not aware of this new regulation having a significant negative impact on decision-making regarding the implementation of pollution controls. It is important to note that state-specific permitting requirements can vary from the new federal regulation.

Speaker #4: Based on the discussions that we have had with our potential client base, we are not aware of this new regulation having a significant negative impact on decision-making regarding the implementation of pollution controls.

Speaker #4: It is important to note that state-specific permitting requirements can vary from the new federal regulation. And it's also important to note that, outside of the NSPS requirements, the use of multiple gas turbines working together can classify them as a major source for NOx.

Vince Arnone: It's also important to note that outside of the NSPS requirements, the use of multiple gas turbines working together classify them as a major source for NOx. Major sources are governed by other regulations and are often required to meet more stringent NOx emissions, which would require SCR. We continue to pursue additional new awards driven by industrial expansion globally and by state-specific regulatory requirements in the US, and we are continuing to monitor the progress of the EPA's rule for large municipal waste combustion units. This rule reduces the nitrogen oxide emissions requirements for up to 150 large MWC units across the country. 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 their compliance planning.

Speaker #4: Major sources are governed by other regulations and are often required to meet more stringent NOx emissions, which would require SCR. We continue to pursue additional new awards driven by industrial expansion globally, and by state-specific regulatory requirements in the U.S.

Speaker #4: 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 their compliance planning.

Vince Arnone: The final rule is currently in the White House Office of Management and Budget and is expected to take effect before the end of March, with NOx emission levels likely requiring advanced SNCR technology to meet compliance deadlines three years from the date of issue. Moving over to DGI. We are continuing the extended demonstration of the technology at a fish hatchery in the Western US, which remains on track to conclude in the Q2 of this year. The system is performing well, meeting customer expectations for the precise delivery of concentrated dissolved oxygen and generating positive results in terms of reduced operational costs and improved fish growth.

Vince Arnone: The system is performing well, meeting customer expectations for the precise delivery of concentrated dissolved oxygen and generating positive results in terms of reduced operational costs and improved fish growth.

Vince Arnone: A second trial that commenced at a municipal wastewater site in the Southeast US was successfully completed in January 2024 and converted to a 6-month rental contract that is expected to run through the beginning of Q3 2024. Our DGI system is delivering the designated volume of oxygen, and the client reports that odor-related complaints in the area surrounding the plant have been dramatically reduced. We are currently in discussions with multiple other end markets of interest for DGI, including pulp and paper, food and beverage, chemical, petrochemical, and horticulture. We have been supported in these efforts with the addition of representative firms with end market expertise. As we look ahead to 2026, we are optimistic about our potential financial outlook.

Speaker #4: A second trial that commenced at a municipal wastewater site in the Southeast US was successfully completed in January of this year, and converted to a six-month rental contract that is expected to run through the beginning of the third quarter of this year.

Speaker #4: And we have been supported in these efforts with the addition of representative firms with end market expertise. As we look ahead to 2026, we are optimistic about our potential financial outlook.

Vince Arnone: Our FUEL CHEM business is expected to continue to perform well, driven by the performance of our base accounts and by the expectation that we will convert another demonstration account to commercial operation. Our APC business development activities, including our standard opportunities, those associated with respect to the Wahlco acquisition, and potential tailwinds from data center opportunities, are at the highest level that we have experienced in several years. Regarding DGI, based on progress at our demonstrations, it is expected that we will have our first commercial contract in 2026.

Speaker #4: Our fuel chem business is expected to continue to perform well, driven by the performance of our base accounts and by the expectation that we will convert another demonstration account to commercial operation.

Consolidated growth margin for Q4 rose to 45% of revenues from 42% in last year's Q4, with APC and FUEL CHEM each producing higher margins for Q4.

Speaker #2: Consolidated gross margin for the fourth quarter rose to 45% of revenues from $42% in last year's fourth quarter with APC and fuel chem each producing higher margins for the quarter.

Ellen Albrecht: FUEL CHEM growth margin increased to 46% from 45% in Q4 2024 due to the increase in the revenue base. APC growth margin expanded significantly to 42% in Q4 compared to 36% in the prior year period as a result of project and product mix. Consolidated APC segment backlog on 31 December 2025 was $7 million, up from backlog of $6.2 million on 31 December 2024. Backlog at the end of 2025 included $3.4 million of domestically delivered project backlog and $3.6 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 the end of 2024.

Speaker #2: Consolidated APC segment backlog on December 31st, 2025, was $7 million up from backlog of $6.2 million on December 31st, 2024. Backlog at the end of 2025 included $3.4 million of domestically delivered project backlog and $3.6 million of foreign delivered project backlog.

Ellen Albrecht: compared to $1.9 million of domestic delivered project backlog and $4.3 million of foreign delivered project backlog at the end of 2024.

Speaker #2: Compared to $1.9 million of domestic delivered project backlog and $4.3 million of foreign delivered project backlog at the end of 2024. We expect that approximately $6 million of current consolidated backlog will be recognized in the next 12 months.

Ellen Albrecht: We expect that approximately $6 million of current consolidated backlog will be recognized in the next 12 months. SG&A expenses were $4.2 million in Q4 compared to $3.9 million in the prior year period. As a percentage of revenue, SG&A expenses declined to 57% from 75%, reflecting higher consolidated revenue in the current period, offset by the timing of certain of certain expenditures. Research and development expenses for Q4 rose to $504,000 from $405,000 in the same period a year ago, mainly attributed to our commercialization efforts for our DGI technology. Our operating loss narrowed to $1.4 million compared to a loss of $2.1 million in last year's Q4, reflecting higher revenue and margin contributions from our operating segment.

Speaker #2: SG&A expenses were $4.2 million in the fourth quarter compared to $3.9 million in the prior year period. As a percentage of revenue, SG&A expenses declined to $57% from $75%, reflecting higher consolidated revenue in the current period.

Speaker #2: Our operating loss narrowed to $1.4 million compared to a loss of $2.1 million in last year's fourth quarter reflecting higher revenue and margin contributions from our operating segment.

Ellen Albrecht: We continue to take advantage of the favorable interest rate environment and, as of 31 December 2025, have invested a majority of our $31.9 million in held-to-maturity debt securities and money market funds. This generated $288,000 of interest income in Q4 and $1.4 million of interest income for 2025. Moving to the results for full year 2025, consolidated revenue rose 6% to $26.7 million, in line with our most recent guidance provided in November. The increase in full year revenue was driven by a 28% rise in FUEL CHEM segment revenue to $17.8 million, exceeding our guidance for the year. This increase in revenue was partially offset by a decrease in APC segment revenue.

Ellen Albrecht: Consolidated growth margin for 2025 rose to 46% from 42% in 2024, with higher margins for both the FUEL CHEM and APC operating segments. SG&A expenses for 2025 modestly increased to $14.1 million from $13.8 million in 2024 within the guidance range we provided at this time last year. The increase was mainly attributed to employee-related expenditures. As a percentage of revenue, SG&A decreased to 53% from 55%, reflecting higher consolidated revenue. For 2026, we expect SG&A expenses to increase modestly from those in 2025. Research and development expenses for the year were $2 million for 2025, compared to $1.6 million in 2024.

Speaker #2: Research and development expenses for the year were $2 million for 2025 compared to $1.6 million in 2024 as we move closer to fully commercializing our DGI segment technologies.

Ellen Albrecht: As we move closer to fully commercializing our DGI segment technologies. In addition, we also continue to invest efforts related to our legacy technologies as necessary. Operating loss narrowed to $3.7 million for 2025, compared to a loss of $4.7 million in 2024, reflecting higher segment revenues and relatively flat total costs and expenses. Net loss for 2025 was $2.3 million or $0.08 per diluted share, compared to a net loss of $1.9 million or $0.06 per diluted share in 2024. Adjusted EBITDA loss was $2.7 million in 2025, compared to an adjusted EBITDA loss of $2.2 million in 2024. Lastly, moving to the balance sheet. Our financial condition remains very strong.

Speaker #3: Our first question comes from Samir Joshi, with HC Wainwright. Please proceed with your question.

Sameer Joshi: Hey, hey, good morning, Vince, Ellen. Thanks for taking my call.

Speaker #4: Yeah. Hey, good morning, Vince, Ellen. Thanks for taking my call.

Vince Arnone: Good morning, Sameer. Good morning.

Sameer Joshi: Good morning. First, the data center opportunity should be significant for the company. You mentioned you're reliant on these integrators or OEMs for getting the final order. My question is, are you already designed in with these participants, or is there further sort of competition once those guys get the orders from data centers?

Speaker #1: Good morning, Samir. Good morning.

Speaker #4: Good morning. So first, the data center opportunity should be significant for the company. You mentioned you're reliant on these integrators or OEMs for getting the final order.

Speaker #4: My question is, are you already designed in with these participants, or is there further sort of competition once those guys get the orders from data centers?

Vince Arnone: I can't say that we were specifically designed in for these operators at this point in time, Sameer. What we're doing is we would obviously, we would like to be at the point whereby we are designed in with an integrator or operator that's looking to build several sites. Right now, at the beginning phase with some of these operators, what we're doing is establishing ourselves as a potential trusted partner to be able to do the design pollution control system for them. A lot of the parties that are coming to us aren't necessarily very familiar with pollution control requirements. We are definitely playing an education role as we work with some of these parties at this point in time.

Speaker #1: I can't say that we're specifically designed in for these operators. At this point in time, Samir, what we're doing is we would obviously we would like to be at the point whereby we are designed in with an integrator or operator that's looking to build several sites.

Speaker #1: But right now, at the beginning phase with some of these operators, what we're doing is establishing ourselves as a potential trusted partner to be able to do the design pollution control system for them.

Speaker #1: A lot of the parties that are coming to us aren't necessarily not necessarily very familiar with pollution control requirements. So we are definitely playing an education role as we work with some of these parties at this point in time.

Vince Arnone: We are definitely playing an education role as we work with some of these parties at this point in time.

Vince Arnone: We are hoping that the upfront time that I mentioned that we are investing with these opportunities is going to pay off a little bit longer term as these projects actually do come through their evolution and are ultimately awarded. That's where we stand today. The situation, I would say, is slightly different, across the different parties that we are dealing with.

Speaker #1: But we are hoping that the upfront time that I mentioned, that we are investing with these opportunities, is going to pay off a little bit longer term as these projects actually do come through their evolution and are ultimately awarded.

Speaker #1: So that's where we stand today. And the situation, I would say, is slightly different across the different parties that we are dealing with.

Sameer Joshi: Got it. Understood. I do not want to conflate this, but the requirements for the less than 85 megawatt plants and short-term working less than 24 months, does that in any way affect or impact these data center opportunities? I just don't want to conflate those, is there any relation?

Speaker #4: Got it. Understood. And I do not want to conflate this, but the requirements for the less-than-85-megawatt plants and short-term working less than 24 months—does that in any way affect or impact these data center opportunities?

Speaker #4: I just—I just don't want to conflate those, but is there any relation?

Vince Arnone: Right. Ultimately, on a long-term basis, that should not have an impact, Sameer, because most of the projects that we read about, most of the projects that we're having discussions about are intended to be long-term power generation solutions for that particular data center, right? It would only be in the instance whereby a potential operator or integrator needed to meet perhaps a very specific start-up date, and they had the ability to have some power generation equipment up and running for a short period of time. To meet that start-up date, again, perhaps, right?

Speaker #1: Right. Ultimately, on a long-term basis, that should not have an impact, Samir. Because most of the projects that we read about, most of the projects that we're having discussions about, are intended to be long-term power generation solutions for that particular data center, right?

Speaker #1: It would only be in the instance whereby a potential operator or integrator needed to meet, perhaps, a very specific startup date, and they had the ability to have some power generation equipment up and running for a short period of time to meet that startup date.

Sameer Joshi: Mm-hmm.

Vince Arnone: Again, from our perspective, the people and party that we are dealing with, they're looking at long-term power generation solutions that are indeed not temporary in nature because they're looking to support that data center long-term, not just for less than 24 months.

Speaker #1: Again, perhaps, right? But again, from our perspective, the people and party that we are dealing with, they're looking at long-term power generation solutions that are indeed not temporary in nature because they're looking to support that data center long-term, not just for less than 24 months.

Sameer Joshi: to sort of a regulatory environment with the EPA declaring carbon dioxide not a pollutant, and you talked about the Mercury and Air Toxics Standards action. And it indirectly helping you because it does not require NOx reductions. And so existing plants may have extended life because of the other reductions in requirement or loosening of requirement. Are you already seeing any increased activity as a result of this, where some of the plants that may be on the way to shut down are now saying that, "Hey, we can work, we can continue to function," and reaching out to you?

Speaker #4: Got it. Sticking to sort of the regulatory environment with the EPA, declaring carbon dioxide not a pollutant, and you talked about the mercury toxins action, and it indirectly helping you because it does not require NOx reductions.

Speaker #4: And so existing plants may have extended reductions, in requirement, or loosening of requirement. Are you already seeing any increased activity as a result of this where some of the plants that may be on the way to shut down are now saying that, "Hey, we can work we can continue to function and reaching out to you"?

Vince Arnone: At this point in time, Sameer, it's a little bit too early to assess the impact of those relatively recent rollbacks. We just wanted to point out very specifically that those rollbacks do not impact Fuel Tech's opportunity to capture prospective awards that are specifically related to nitrogen oxide reduction opportunities. We just want to ensure that there isn't confusion related to those rollbacks, which are not going to impact Fuel Tech business opportunities. Longer term, those rollbacks, they could indeed have the impact of it possibly extending the useful lives of some facilities.

Speaker #1: Yeah. At this point in time, Samir, it's a little bit too early to assess the impact. Of those relatively recent rollbacks, we just wanted to point out very specifically that those rollbacks do not impact fuel tech's opportunity to capture prospective awards that are specifically related to nitrogen oxide reduction opportunities.

Speaker #1: So we just want to ensure that there isn't confusion related to those rollbacks, which are not going to impact fuel tech business opportunities. Longer term, those rollbacks, they could indeed have the impact of possibly extending the useful lives of some facilities.

Sameer Joshi: Got it. Thanks for that.

Vince Arnone: You're welcome.

Sameer Joshi: Moving to FUEL CHEM. It's nice to see the six-month sort of trial order, and likely, because they are seeing the results, are likely to convert. Are there more such potential customers that you have in the pipeline or are at least talking to in terms of getting? Because each additional customer could bring $2+ million or almost $4+ million in orders, annual recurring revenues.

Speaker #1: You're welcome.

Speaker #4: And then moving to fuel chem it's nice to see the six-month sort of trial order and likely because they are seeing the results, likely to convert.

Speaker #4: Are there more such potential customers that you have in the pipeline or at least talking to in terms of getting because each additional customer could bring two-plus million or almost four-plus million in orders annual recurring revenues?

Vince Arnone: At this point in time, and yes, we're very optimistic about converting this demonstration to a commercial contract. Hopefully, that will bode well for us here in 2026. Incrementally, as I've said on prior conference calls, the coal-fired base-loaded unit, just call it phenomena, it isn't as robust as it used to be a decade or 15 years ago, with so many coal-fired plants being shut down. We are looking for these pockets of opportunity whereby we can on an incremental basis, add these one-off opportunities for us, okay?

Speaker #1: I just know at this point in time, and yes, we're very optimistic about converting this demonstration to a commercial contract. Hopefully, that will bode well for us here in 2026.

Speaker #1: But incrementally, as I've said on prior conference calls, the coal-fired base-loaded units—just call it phenomena—it isn't as robust as it used to be a decade or 15 years ago.

Speaker #1: With so many coal-fired plants being shut down, we are looking for these pockets of opportunity whereby we can, on an incremental basis, add these one-off opportunities for us, okay?

Vince Arnone: We need to be a little bit careful about saying that each incremental unit is going to be between $2 million and $3 million per opportunity in revenue, because it does vary by unit size and the specific runtime of that unit. I just wanted to qualify that.

Speaker #1: And we need to be a little bit careful about saying that each incremental unit is going to be between $2 million and $3 million per opportunity in revenue.

Speaker #1: Because it does vary by unit size and the specific runtime of that unit. So I just wanted to qualify that. So to specifically answer your question, we don't have anything what I would call specifically that we're looking for imminent demonstration, but we are looking at some other opportunities that could be for us and perhaps with the same body of plants that we're doing business with today.

Sameer Joshi: Yeah.

Vince Arnone: To specifically answer your question, we don't have anything or what I would call specifically that we're looking for imminent demonstration. We are looking at some other opportunities that could be for us and perhaps with the same body of plants that we're doing business with today to add another unit or two at plant sites. There is opportunity there. Again, as I've said previously, we haven't looked at FUEL CHEM® as being what I would call a material growth opportunity for the past several years. What we're seeing here in the recent term, we're very pleased with. We finished 2025 at just under $18 million revenue, which if you had asked me that question 5 years ago, I would have said it wouldn't have been possible.

Speaker #1: To add another unit or two at plant sites. So there is opportunity there, but again, as I've said previously, we haven't looked at fuel chem as being what I would call a material growth opportunity for the past several years.

Speaker #1: What we're seeing here in the recent term, we're very, very pleased with. We finished 2025 at just under 18 million in revenue, which if you had asked me that question five years ago, I would have said it wouldn't have been possible.

Vince Arnone: We finished 2025 at just under $18 million revenue, which if you had asked me that question 5 years ago, I would have said it wouldn't have been possible.

Vince Arnone: We're very pleased with where we are. There is some, I'll call it moderate upside opportunity, but it is moderate.

Speaker #1: So we're very pleased with where we are. And there is some I'll call it moderate upside opportunity. But it's moderate.

Sameer Joshi: Right. Right. Just, I'm guessing this outlook for 2026, where FUEL CHEM is expected to be at same levels as 2025, does not include this incremental opportunity that may convert into like a full from trial to full-time.

Speaker #4: Right. Great. And just—I'm guessing this outlook for 2026, where Fuel Chem is expected to be at the same levels as 2025, does not include this incremental opportunity that may convert from trial to full-time.

Vince Arnone: Yeah. We're looking at it right now very, very conservatively, Sameer, without knowing exactly what the outcome is going to be as we sit here today. We'll have more information to share in early May when we have our Q1 conference call.

Speaker #1: Yeah. We're looking at it right now very conservatively. Samir, without knowing exactly what the outcome is going to be as we sit here today, we'll have more information to share in early May when we have our first quarter conference call.

Sameer Joshi: Yes. That's fair. Just squeezing in one last one on DGI. It seems this fishery that, sorry, municipal wastewater, it seems to be working well, as well as the fishery seems to be working well. Should we expect revenues from DGI during 2026? On the outlook, you didn't mention any of that.

Speaker #4: Yes. And that's fair. And just squeezing in one last one on DGI. It seems this fishery that sorry, municipal wastewater is it seems to be working well as well as the fishery seems to be working well.

Speaker #4: Should we expect revenues from DGI during 2026 because on the outlook, you didn't mention any of that?

Vince Arnone: Right. We are going to recognize a small dollar value of revenue from the rental of the system at the municipality. That's only $10,000 per month. As we look at the remainder of the year, we are hoping to have a system sale between now and the end of 2026 of one of our DGI units. It's not going to be material to our overall results, but what is important regarding that activity is it sets a platform for us to be able to further and go ahead and discuss a success story specifically with the end markets that we're looking to chase. We haven't had the opportunity to do that yet.

Speaker #1: Right. So we are going to recognize a small dollar value of revenue from the rental of the system at the municipality. That's only $10,000 per month.

Speaker #1: As we look at the remainder of the year, we are hoping to have a system sale between now and the end of 2026 of one of our DGI units.

Speaker #1: It's not going to be material to our overall results. But what is important regarding that activity is it sets a platform for us to be able to further and go ahead and discuss a success story, specifically with the end markets that we're looking to chase.

Vince Arnone: That moment is extremely critical for us as we look to further, develop, and commercialize DGI.

Speaker #1: And we haven't had the opportunity to do that yet. So that moment is extremely critical for us as we look to further develop and commercialize DGI.

Sameer Joshi: Understood. Thanks, Vince, for taking my questions. Congrats on a strong year, and good luck.

Speaker #4: Understood. Thanks, Vincent, getting my questions. Congrats on a strong year and good luck.

Vince Arnone: Thanks, Amir.

Speaker #1: Thanks, Samir.

Devin Sullivan: As a reminder, if you'd like to ask a question, please press star one on your telephone keypad. One moment, please, while we poll for questions. Our next question comes from Adam Waldo with Lismore Partners. Your line is now live.

Speaker #3: As a reminder, if you'd like to ask a question, please press star one on your telephone keypad. One moment, please, while we poll for questions.

Speaker #3: Our next question comes from Adam Waldo with Lismore Partners. Your line is now live.

Adam Waldo: Good day, Vince. I hope you can hear me okay.

Vince Arnone: Yes, we can, Adam. Thank you.

Speaker #5: Good day, Vince. I hope you can hear me okay.

Adam Waldo: Very high-level question. Your stock trades at $1.20, $1.25 a share. You have about $1 a share in cash on your balance sheet. You have reasonable prospect of being cash flow positive in 2026, and you articulate a sizable new business pipeline in the data center area. I would argue that with your stock trading where it is, the market doesn't believe you're gonna close any of that pipeline. You're very optimistic that you can over the balance of 2026, and you were optimistic in the second half of 2025 as well. The timing of these projects is very hard to predict. What gives you so much confidence and optimism that you're gonna close, you know, a sizable number of data center projects over the next 12 to 18 months?

Speaker #1: Yes, we can, Adam. Thank you.

Speaker #5: So, very high-level question. Your stock trades at $1.20, $1.25 a share. You have about $1.00 a share in cash on your balance sheet. You have reasonable prospect of being cash flow positive in 2026.

Speaker #5: And you articulate a sizable new business pipeline in the data center area. I would argue that with your stock trading where it is, the market doesn't believe you're going to close any of that pipeline.

Speaker #5: You're very optimistic that you can. Over the balance of 2026, and you were optimistic in the second half of 2025 as well. The timing of these projects is very hard to predict.

Adam Waldo: What gives you so much confidence and optimism that you're gonna close, you know, a sizable number of data center projects over the next 12 to 18 months?

Speaker #5: What gives you so much confidence and optimism that you're going to close a sizable number of data center projects over the next 12 to 18 months?

Vince Arnone: Adam, thanks very much for the question. Yeah, you're correct. I mean, we're in a position whereby, yes, we're trading just a little bit above cash value today. We, as a company, have not been able to go ahead and bring to the table any material award as of yet as it relates to the data center opportunity. In response to your question, my level of confidence lies in a couple of areas. First of all, as we've seen this opportunity develop and literally over the past 9 to 12 months, because it is still a, what I would call a new opportunity, and it's one that we don't believe as Fuel Tech is a short-term opportunity.

Speaker #1: Adam, thanks very much for the question. You're correct. I mean, we're in a position whereby, yes, we're trading just a little bit above cash value.

Speaker #1: Today. We as a company have not been able to go ahead and bring to the table any material award as of yet as it relates to the data center opportunity.

Speaker #1: So in response to your question, my level of confidence lies in a couple of areas. First of all, as we've seen this opportunity develop and literally over the past 9 to 12 months because it's it is still a what I would call a new opportunity.

Speaker #1: And it's one that we don't believe as fuel tech is a short-term opportunity. It's one that's going to develop over the next 5 to 10 years.

Vince Arnone: It's one that's going to develop over the next 5 to 10 years. What we have seen over this past 9 to 12 months is more and more players, if you will, players defined as data center integrators, parties that have access to power generation equipment in the form of turbines or engines and just then the OEMs of those turbines or engines themselves. There have been more inquiries come our way literally over this past 3 months than we saw come our way or over the initial 6 to 9 months relative to parties seeking to take advantage of the opportunity to provide power generation solution to the data centers that are going to be built out. Okay?

Speaker #1: But what we have seen over this past 9 to 12 months is more and more players if you will, players defined as data center integrators, parties that have access to power generation equipment in the form of turbines or engines and just then the OEMs of those turbines or engines themselves there have been more inquiries come our way literally over this past three months than we saw come our way or over the initial 6 to 9 months.
