Richard MacPherson: Thank you, operator, and good afternoon, everyone. Welcome to our Q4 and full year 2025 financial results conference call. I want to start with a few milestones that reshaped the company's trajectory over the past several months. In February 2026, we completed our uplisting to the NYSE American with a concurrent public offering, raising a gross amount of proceeds of approximately $16.6 million, including the partial exercise of the underwriter's overallotment option. That capital raise, combined with a senior exchange listing, materially strengthened our balance sheet and broadened our investor base at a critical time in Birchtech's growth. Now on the legal front, the U.S. District Court for the District of Delaware entered our patent infringement judgment in December 2025, which increased our judgment amount to approximately $78 million, up from the original $57 million unanimous jury verdict.

Speaker #2: Thank you, operator. And good afternoon, everyone. Welcome to our fourth quarter and full year 2025 financial results conference call. I want to start with a few milestones that reshaped the company's trajectory over the past several months.

Speaker #2: In February of 2026, we completed our uplisting to the New York American Stock Exchange with a concurrent public offering raising a gross amount of proceeds of approximately $16.6 million.

Speaker #2: Including the partial exercise of the underwriters' overall allotment option. That capital raise, combined with a senior exchange listing, materially strengthened our balance sheet and broadened our investor base at a critical time in Birchtech's growth.

Speaker #2: Now, on the legal front, the US District Court for the District of Delaware entered our patent infringement judgment in December of 2025, which increased our judgment amount to approximately $78 million.

Speaker #2: Up from the original $57 million unanimous jury verdict. Post-judgment interest will continue to accrue until this judgment is paid. Although defendants have filed an appeal, they have not posted a bond.

Richard MacPherson: Post-judgment interest will continue to accrue until this judgment is paid. Although defendants have filed an appeal, they have not posted a bond. Therefore, we have initiated collection proceedings and are pursuing enforcement of our judgment now. Since launching our IP enforcement strategy in 2019, approximately $37 million in license fees and settlements have been received, and we expect to convert other prior infringers into long-term commercial partners. Now turning to operations. Our business delivered Q4 revenues of $3.8 million, with a 31% gross margin driven by our expanding base of licensed utilities and growing product supply relationships. The US coal market has stabilized, and recent federal support for continued coal plant operation reinforces demand for proven emissions control solutions like our patented SEA platform. We believe this creates a longer operational runway for our core air quality business.

Speaker #2: Therefore, we have initiated collection proceedings, are pursuing enforcement of our judgment now. Since launching our IP enforcement strategy in 2019, approximately $37 million in license fees and settlements have been received.

Speaker #2: We expect to convert other prior infringers into long-term commercial partners. Now, turning to operations, our business delivered fourth-quarter revenues of $3.8 million, with a 31% gross margin driven by our expanding base of licensed utilities and growing product supply relationships.

Speaker #2: The US coal market has stabilized, and recent federal support for continued coal plant operation reinforces demand for proven emissions control solutions like our patented SEA platform.

Speaker #2: We believe this creates a longer operational runway for our core air quality business. Now, let me go deeper now into our air business. The SEA platform continues to anchor the company, and this quarter's results reflect the durability of that franchise.

Richard MacPherson: Now, let me go deeper into our air business. The SEA platform continues to anchor the company, and this quarter's results reflect the durability of that franchise. What has changed is the nature of the revenue. As existing supply contracts expire for those utilities now under Birchtech's license agreements, we will actively work toward gaining their recurring product supply as utilities embed our sorbent formulations into the processes and directly benefit from our operational expertise and know-how. Q4 air revenues totaled over $3 million, close to $4 million, and mostly derived from product supply. Importantly, we expect to see a change in how utilities engage with us, with our goal being that licenses that began as enforcement targets can transition to purchasing activated carbon directly. We expect the pipeline of supply conversions to continue to grow as power demand increases in the coming years.

Speaker #2: What has changed is the nature of the revenue, as existing supply contracts expire for those utilities now under Birchtech's license agreements we will actively work toward gaining their reoccurring product supply as utilities embed our sorbent formulations into the processes and directly benefit from our operational expertise and know-how.

Speaker #2: Fourth-quarter air revenues totaled over $3 million, close to $4 million, and were mostly derived from product supply. Importantly, we expect to see a change in how utilities engage with us, with our goal being that licenses that began as enforcement targets can transition to purchasing activated carbon directly.

Speaker #2: And we expect the pipeline of supply conversions to continue to grow as power demand increases in the coming years. That transition from legal resolution to commercial partnership was our core objective in our business-first approach patent enforcement efforts that began over six years ago.

Richard MacPherson: That transition from legal resolution to commercial partnership was our core objective in our business-first approach patent enforcement efforts that began over six years ago. Now, over the past year, we've signed several new license agreements, bringing us closer to a critical mass of licensed coal-fired utilities. Each agreement not only validates the uniqueness of our SEA process but extends revenue visibility through multi-year procurement cycles. As licensees incorporate our sorbent formulations into their ongoing operations, we expect activated carbon sales to become an increasingly significant portion of our revenue, a shift that should drive meaningful year-over-year growth. As I noted earlier, our $78 million final judgment represents the culmination of years of patent enforcement. The defendants have appealed, but we are confident in the strength of our ruling and the thorough judicial review behind it. Collection efforts, as I mentioned, are actively underway.

Speaker #2: Now, over the past year, we've signed several new license agreements bringing us closer to a critical mass of licensed coal-fired utilities. Each agreement not only validates the uniqueness of our SEA process, but extends revenue visibility through multi-year procurement cycles.

Speaker #2: As licensees and corporate are sorbent formulations into their ongoing operations, we expect activated carbon sales to become an increasingly significant portion of our revenue—a shift that should drive meaningful year-over-year growth.

Speaker #2: As I noted earlier, our $78 million final judgment represents the culmination of years of patent enforcement. The defendants have appealed, but we are confident in the strength of our ruling and the thorough judicial review behind it.

Speaker #2: Collection efforts, as I mentioned, are actively underway. Now, related to our air business, US coal power generation is holding steady within a diversified energy mix that values grid reliability as well as domestic fuel supply.

Richard MacPherson: Now, related to our business, US coal power generation is holding steady within a diversified energy mix that values grid reliability as well as domestic fuel supply. Federal policy continues to support the operational longevity of coal-fired plants, which in turn sustains demand for mercury emissions control. Our SEA technology remains the most effective solution globally recognized, and that positions us as an essential partner for utilities committed to running cleaner baseload power. With US mercury emissions the lowest in the world relative to coal power generation, we're pleased to play a significant role in America's clean coal and will continue to do so as long as coal power is produced. For 2026, the air division's roadmap centers on three objectives. Continue converting unlicensed users to our technology into licensees and long-term supply customers while protecting our patents.

Speaker #2: Federal policy continues to support the operational longevity of coal-fired plants, which in turn sustains demand for mercury emissions control. Our SEA technology remains the most effective solution, globally recognized, and that positions us as an essential partner for utilities committed to running cleaner base-load power.

Speaker #2: With U.S. mercury emissions the lowest in the world relative to coal power generation, we're pleased to play a significant role in America's clean coal, and will continue to do so as long as coal power is produced.

Speaker #2: For 2026, the Air Division's roadmap centers on three objectives: continue converting unlicensed users of our technology into licensees and long-term supply customers, while protecting our patents.

Richard MacPherson: Second, grow recurring activated carbon sales to our expanding base of licensed utilities. Thirdly, channel the cash flow from this mature high-margin segment into our scaling of our water purification business. Now, taken together, the air division is a self-funded growth engine generating the cash and credibility that allow us to invest aggressively in water while continuing to deliver for shareholders. Now let me turn to water, where the story shifted meaningfully since last year. We moved from laboratory validation to real commercial activity, booking our first revenues, signing our first strategic partnership, and launching new products. The commercialization of our water treatment solutions began with approximately $0.9 million in purchase orders from a large Mid-Atlantic power utility for filtration system media replacement at two locations, removing contaminants from wastewater using our proprietary sorbent media.

Speaker #2: Second, grow reoccurring activated carbon sales to our expanding base of licensed utilities. And thirdly, channel the cash flow from this mature high-margin segment into our scaling of our water purification business.

Speaker #2: Now, taken together, the Air division is a self-funded growth engine, generating the cash and credibility that allow us to invest aggressively in Water, while continuing to deliver for shareholders.

Speaker #2: So now let me turn to water. Where the story shifted meaningfully since last year. We moved from laboratory validation to real commercial activity. Booking our first revenues, signing our first strategic partnership, and launching new products.

Speaker #2: The commercialization of our water treatment solutions began with approximately $0.9 million in purchase orders from a large Mid-Atlantic power utility for filtration system media replacement at two locations: removing contaminants from wastewater using our proprietary sorbent media.

Richard MacPherson: That engagement validated our technology in a real utility environment and gave us a reference account to build from. We then expanded our reach through a collaboration with Civil & Environmental Consultants, a national engineering firm with over 30 offices and 1,600 team members. Under this arrangement, we provide rapid small-scale column testing through our analytical design center in Grand Forks, North Dakota, giving CEC's hundreds of water utility clients nationwide access to our testing and analysis capabilities. This effectively creates a pipeline of future system design and media supply opportunities without Birchtech having to build a direct sales force from scratch. For those less familiar, our RSSCT replicates full-scale filter performance in a compressed time frame, enabling utilities to evaluate carbon media options and PFAS removal strategies quickly and cost-effectively.

Speaker #2: That engagement validated our technology in a real utility environment and gave us a reference account to build from. We then expanded our reach through a collaboration with civil and environmental consultants, a national engineering firm with over 30 offices and 1,600 team members.

Speaker #2: Under this arrangement, we provide rapid, small-scale column testing through our analytical design center in Grand Forks, North Dakota. Giving CECs hundreds of water utility clients nationwide access to our testing and analysis capabilities.

Speaker #2: This effectiveness creates a pipeline of future system design and media supply opportunities without Birchtech having to build a direct sales force from scratch. For those less familiar, our SSCT replicates full-scale filter performance in a compressed timeframe, enabling utilities to evaluate carbon media options and PFAS removal strategies quickly and cost-effectively.

Richard MacPherson: Our center is one of the few independent RSSCT labs in the country with the capacity to serve the national market at this level. Beyond those two anchors, we hit several additional milestones. In January 2026, we demonstrated that thermally rejuvenated granular activated carbon performs comparably to virgin carbon for PFAS removal. It was a breakthrough for our carbon rejuvenation program that could dramatically lower lifecycle costs for utilities. This week, we just announced our SEA-IX nuclear-grade ion exchange resin product line, targeted at an approximate $220 million addressable market, spanning nuclear power, coal-fired utilities, and municipal water treatment. BirchTech's water platform covers a broad range of media supply, filtration services, our design centers, our RSSCT testing and analysis, along with carbon rejuvenation. Now ion exchange resins. We have a comprehensive offering that didn't exist twelve months ago.

Speaker #2: Birchtech's water platform covers a broad range of media supply filtration services. Our design centers are SSCT testing and analysis, along with carbon rejuvenation, and now ion exchange resins.

Speaker #2: So we have a comprehensive offering that didn't exist 12 months ago. Our approach to the market is completely different than our competitors. We work closely with and through engineering firms such as CEC and others alongside utilities to fully integrate the procurement of appropriate equipment, media, and other end-sale reserves.

Richard MacPherson: Our approach to the market is completely different than our competitors. We work closely with and through engineering firms such as CEC and others, alongside utilities to fully integrate the procurement of appropriate equipment, media, and other ancillary services. This collaborative approach to the market will ensure water utilities with an affordable, highly effective clean water solution and will secure Birchtech's strong market position as we continue to build customers and strategic relationships. Now, speaking of our design centers that launched our position into the water treatment market with our data-first approach, we are now generating a growing pipeline of lab scale engagements with water utilities and engineering firms.

Speaker #2: This collaborative approach to the market will ensure water utilities with an affordable, highly effective clean water solution, and will secure Birchtech's strong market position as we continue to build customers and strategic relationships.

Speaker #2: Now, speaking of our design centers that launched our position into the water treatment market with our data-first approach, we are now generating a growing pipeline of lab-scale engagements with water utilities and engineering firms.

Richard MacPherson: We are currently participating in a grant-funded research project with a leading national engineering firm, evaluating strategies for managing PFAS-contaminated drinking water waste, where Birchtech is leading advanced bench and pilot scale testing of thermal GAC reactivation using our proprietary rotary kiln system that we established in Pennsylvania. Other key projects include our role in the initial phase of a multi-phase project, where we are collaborating with another major national engineering firm and a large utility focused on carbon reactivation to identify the most appropriate media solutions for the removal of multiple contaminants. Our expertise in activated carbons provides our competitive edge and our ability to support both the engineering firm and the large water utility.

Speaker #2: Our expertise in activated carbons provides our competitive edge and our ability to support both the engineering firm and the large water utility. And additionally, we're conducting water quality analysis spent carbon evaluations and RSSCT testing for numerous other utilities to optimize media selection reactivation protocols and overall treatment performance for PFAS and other contaminants.

Richard MacPherson: Additionally, we're conducting water quality analysis, spent carbon evaluations, and RSSCT testing for numerous other utilities to optimize media selection, reactivation protocols, and overall treatment performance for PFAS and other contaminants. Each of these engagements is building relationships that have the potential to convert into long-term thermal reactivation partnerships or feed directly into our water treatment services pipeline. This data-first approach ensures that these utilities and engineering firms gain highly accurate and more effective media recommendations and receive full benefit from our unique industry expertise. We look forward to this area of our business becoming a key market differentiator and growth driver. The next chapter is about conversion and scale, turning these early engagements into recurring service and product revenue, progressing the development of our first GAC rejuvenation facility, and expanding our water treatment solution offerings.

Speaker #2: Turning these early engagements into reoccurring service and product revenue progressing the development of our first GAC rejuvenation facility and expanding our water treatment solution offerings.

Richard MacPherson: Regulatory pressure around PFAS is only intensifying, and utilities are actively seeking affordable solutions. Birchtech is now in position to meet that demand with a full suite of water purification technologies that complement our established air business and open a second significant revenue stream for the company. With that, I'd now like to turn the call over to Fiona Fitzmaurice, our Chief Financial Officer, to walk through some key financial details from Q4 2025. Fiona?

Speaker #2: Regulatory pressure around PFAS is only intensifying, and utilities are actively seeking affordable solutions. Birchtech is now in position to meet that demand with a full suite of water purification technologies that complement our established air business and open a second significant revenue stream for the company.

Speaker #2: With that, I'd now like to turn the call over to Fiona Fitzmorris, our Chief Financial Officer, to walk through some key financial details from the fourth quarter of 2025.

Fiona Fitzmaurice: Thank you, Rick. I will constrain my section to a concise review of the financial results for Q4. For a full breakdown of our financial results, please view our regulatory filings. Revenues totaled $3.8 million in Q4 as compared to $5.6 million in the same year ago quarter. Product revenues increased 19.8% to $3.6 million, as compared to $3 million in the same year ago quarter. The change in revenues was primarily due to a one-time $2.5 million licensing payment from a large Southwest utility in Q4 2024. Gross profit totaled $1.2 million or 31% of total revenues in Q4 2025, as compared to $3.3 million or 60% of total revenues in the same year ago quarter.

Speaker #2: Fiona? Thank you, Rick. I will constrain my section to a concise review of the financial results for the fourth quarter. For a full breakdown of our financial results, please view our regulatory filings.

Speaker #2: Revenues totaled $3.8 million in the fourth quarter, as compared to $5.6 million in the same year-ago quarter. Product revenues increased 19.8% to $3.6 million, as compared to $3 million in the same year-ago quarter.

Speaker #2: The change in revenues was primarily due to a one-time $2.5 million licensing payment from a large Southwest utility in Q4, 2024. Gross profit totaled $1.2 million or $31% of total revenues in the fourth quarter of 2025 as compared to $3.3 million or 60% of total revenues in the same year-ago quarter.

Fiona Fitzmaurice: The change in gross profit was a result of the one-time license fee recognized in Q4 of 2024. This change was partially offset by an increase in product revenue during the Q4 of 2025 compared to the Q4 of 2024. The decrease in gross profit as a percentage of revenues was a result of the one-time license revenue generated in the Q4 of 2024 having higher margin. SG&A expenses decreased 42% to $2 million in the Q4 of 2025, as compared to $3.4 million in the same year ago quarter. The decrease in expenses was primarily due to lower legal fees in connection with patent litigation. R&D expenses totaled $0.5 million in the Q4 of 2025 compared to nil in the same year ago quarter.

Speaker #2: The change in gross profit was a result of the one-time license fee recognized in Q4 2024. This change was partially offset by an increase in product revenue during the fourth quarter of 2025 compared to the fourth quarter of 2024.

Speaker #2: The decrease in gross profit as a percentage of revenues was due to revenue generated in the fourth quarter of 2024 having higher margin. SG&A expenses decreased 42% to $2 million in the fourth quarter of 2025, as compared to $3.4 million in the same year-ago quarter.

Speaker #2: The decrease in expenses was primarily due to lower legal fees in connection with patent litigation. R&D expenses totaled $0.5 million in the fourth quarter of 2025, compared to nil in the same year-ago quarter.

Fiona Fitzmaurice: R&D expenses relate to research conducted to develop water treatment products utilizing new sorbent technologies. Net loss for Q4 2025 totaled $0.6 million, or $0.03 per basic and diluted share, as compared to $1.3 million or $0.07 per basic and diluted share. Adjusted EBITDA, a non-GAAP measure, totaled -$1.1 million in Q4 2025, compared to -$0.5 million in Q4 2024. Cash as of December 31, 2025 totaled $2.2 million, with no debt, as compared to $3.5 million with no debt as of December 31, 2024. Subsequent to the quarter end, the company completed a $16.6 million capital raise concurrent with its uplisting to the NYSE American in February 2026, significantly strengthening our balance sheet.

Speaker #2: R&D expenses relate to research conducted to develop water treatment products utilizing use-orbance technologies. Net loss for the fourth quarter of 2025 totaled $0.6 million, or $0.03 per basic undiluted share, as compared to $1.3 million, or $0.07 per basic undiluted share.

Speaker #2: Adjusted EBITDA, a non-GAAP measure, totaled -$1.1 million in the fourth quarter of 2025, compared to -$0.5 million in the fourth quarter of 2024. Cash as of December 31, 2025, totaled $2.2 million with no debt, as compared to $3.5 million with no debt as of December 31, 2024.

Speaker #2: Subsequent to the quarter end, the company completed a $16.6 million capital raise concurrent with its uplisting to the New York Stock Exchange American in February 2026, significantly strengthening our balance sheet.

Fiona Fitzmaurice: I'd also like to briefly discuss the classification of our profit share liability in the amount of $7.9 million as a current liability on our balance sheet. This is a non-recourse liability that will not be repaid from cash on hand and is only to be paid from litigation proceeds, including the proceeds of our $78 million final judgment in our patent infringement case. Interest on the judgment amount continues to accrue during this appeal period. Under GAAP accounting rules, the profit share liability is classified as a current liability as the company expects the proceeds from this judgment are likely to be received and the profit share from those proceeds repaid within the next 12 months.

Speaker #2: I'd also like to briefly discuss the classification of our profit share liability in the amount of $7.9 million as a current liability on our balance sheet.

Speaker #2: This is a non-recourse liability that will not be repaid from cash on hand and is only to be paid from litigation proceeds, including the proceeds of our $78 million final judgment in our patent infringement case.

Speaker #2: Interest on the judgment amount continues to accrue during this appeal period. Under GAAP accounting rules, the profit share liability is classified as a current liability, as the company expects the proceeds from this judgment are likely to be received and the profit share from those proceeds repaid within the next 12 months.

Fiona Fitzmaurice: Ironically, the positive news of us believing receipt of these funds is likely within the next 12 months causes the profit share to be classified as a current liability, while at the same time not allowing us to reflect in our current financial statements the expected revenue from the judgment. This completes my prepared comments. Now, before we begin our question and answer session, I'd like to turn the call back to Rick for some closing remarks. Rick.

Speaker #2: So, ironically, the positive news of us believing receipt of these funds is likely within the next 12 months causes the profit share to be classified as a current liability, while at the same time, not allowing us to reflect in our current financial statements the expected revenue from the judgment.

Speaker #2: This completes my prepared comments. Now, before we begin our question-and-answer session, I'd like to turn the call back to Rick for some closing remarks.

Richard MacPherson: Thank you, Fiona. Folks, to sum up, 2025 was the year Birchtech proved out its next chapter. We have since fortified our balance sheet with a $16.6 million raise in new capital, earned a senior exchange listing on the NYSE American, secured a $78 million judgment validating our IP, and turned our water business from a development stage initiative into a revenue-generating platform with real customers and real orders. The execution plan for 2026 is focused. Collect on our judgment, expand our roster of licensed utilities into recurring supply customers, and obtain offtake agreements to support our first carbon rejuvenation facility. We entered the year from a position of strength, well-capitalized, listed on a senior exchange, and operating two complementary business lines that reinforce each other.

Speaker #2: Rick?

Speaker #3: Thank you, Fiona. So folks, to sum up, 2025 was the year Birchtech proved on its next chapter. We have since fortified our balance sheet with a $16.6 million raise in new capital, earned a senior exchange listing on the New York Stock Exchange, secured a $78 million judgment validating our IP, and turned our water business from a development-stage initiative into a revenue-generating platform with real customers and real orders.

Speaker #4: Good afternoon, Rick, and congratulations on all the progress.

Richard MacPherson: Thank you, Rob.

Rob Brown: Two questions on the air business product revenue. Could you give a sense of what the sort of run rate is on that business as you see it and maybe how it ramps throughout 2026 with the customers that you've licensed to this point?

Speaker #3: Thank you, Rob.

Speaker #4: The question’s on the Air business product revenue. Could you give us a sense of what the sort of run rate is on that business as you see it, and maybe how it ramps throughout ’26 with the customers that you’ve licensed to this point?

Richard MacPherson: Sure. On the product supply side, we had an increase, as you can see, in the last quarter of 2025. I expect to see increases as we go through 2026. The only unknown on that is when the actual contracts that are held by the companies that we just licensed will come up for renewal. As they come up for renewal, we're in a preferred position to vie for that business through RFPs. I'll be advising the industry as we go along, but I do expect to see growth in that side of the business. I just at this point can't put a number on it, but I will expect to be able to do so in the coming month or two.

Speaker #3: Sure. So on the product supply side, we had an increase, as you can see, in the last quarter of 2025. I expect to see increases as we go through 2026.

Speaker #3: The only unknown on that is when the actual contracts that are held by the companies that we just licensed will come up for renewal.

Speaker #3: As they come up for renewal, we're in a preferred position to vie for that business through RFPs. So I'll be advising the industry as we go along, but I do expect to see growth in that side of the business.

Speaker #3: I just, at this point, don't—I can't put a number on it, but I will expect to be able to do so in the coming month or two. I do figure that we will be in excess of $20 million on the air side for 2026.

Richard MacPherson: I do figure that we will be in excess of $20 million on the air side for 2026.

Rob Brown: Okay, great. On the remaining customers, I guess that or utilities, I should say, that are, you know, potentially infringing or are infringing, how many are left to settle that you haven't either gone to trial on or settled with yet? What's sort of the remaining amount of potential there?

Speaker #4: Okay, great. And then, on the remaining customers—I guess, utilities, I should say—that are potentially infringing or are infringing, how many are left to settle with that you haven't either gone to trial on or settled with yet?

Speaker #4: What's sort of the remaining amount of potential there?

Richard MacPherson: Sure. There, Rob, there are a couple of very large defendants in the ITC case that have significant product supply potential. We are now, you know, as you know, working through that case. I would expect that we can get to some decision with those in H1 2026. But they have a significant amount of opportunity should we be able to convert them to clients, rather than have them remain as defendants. You know, they, as far as the specific number, I would expect that the outstanding infringers at this point hold somewhere in the $10 million a year range of supply side business, should we secure it.

Speaker #3: Sure. So, Rob, there are a couple of very large defendants in the Iowa case that have significant product supply potential, and we are now, as you know, working through the case.

Speaker #3: I would expect that we can get to some decision with those in the first half of 2026. But they have a significant amount of opportunity should we be able to convert them to clients, rather than have them remain as defendants.

Speaker #3: So as far as a specific number, I would expect that the outstanding infringers at this point hold somewhere in the $10 million a year range of supply-side business should we secure it.

Rob Brown: Okay, great. Just maybe moving to the water side business. Good progress there. Maybe just a sense of the pipeline of the rejuvenation customers, and maybe can you walk through how that pipeline develops and what are the sort of steps that it goes through to turn into offtake agreements?

Speaker #4: Okay, great. Great. And then just maybe moving to the water side—good progress there. Maybe just a sense of the pipeline of the rejuvenation customers, and maybe can you walk through how that pipeline develops and what are the steps that it goes through to turn into offtake agreements?

Richard MacPherson: Yeah. Where we are right now is working through the collaborations with engineering firms. We've been doing a lot of testing and analytical work and with their clients. Also we've been in discussions with a number of different end users, water utilities that would be interested in us either building a rejuvenation center for them on-site or in a regional location nearby where we would be able to provide our rejuvenation services to them. We're still in the negotiation side of that. We have yet to sign any actual offtake agreements. We're in some great discussions right now and continuing to move forward to present that option to a number of different new utilities as well.

Speaker #3: Yeah, so where we are right now is working through the collaborations with engineering firms. We've been doing a lot of testing and analytical work.

Speaker #3: With their clients and also, we've been in discussions with a number of different end users, water utilities that would be interested in us either building a rejuvenation center for them on-site or in a regional location nearby, where we would be able to provide our rejuvenation services to them.

Speaker #3: We're still in the negotiation side of that. We have yet to sign any actual offtake agreements, but we're in some great discussions right now and continuing to move forward to present that option to a number of different new utilities as well.

Richard MacPherson: What's significant is we've basically become you know, the tip of the spear for a lot of these engineering firms with regards to the analytical work that's necessary to be able to go back to their clients and provide some real tight assessment as to what their situation is and what can be done to get ahead of the PFAS problem. We're a very firm part of the solution of the process. We think that will lead to longer term work for us, not just the analytical work. What we're shooting for, of course, is to have the offtake agreements signed where we can do a collaborative effort of building out the regional facilities that we feel they're going to need.

Speaker #3: What's significant is we basically become the tip of the spear for a lot of these engineering firms with regards to the analytical work that's necessary to be able to go back to their clients and provide some real tight assessment as to what their situation is, and what can be done to get ahead of the PFAS problem.

Speaker #3: So, we are a very firm part of the solution, of the process, and we think that that will lead to longer-term work for us, not just the analytical work. What we're shooting for, of course, is to have the offtake agreements signed, where we can do a collaborative effort of building out the regional facilities that we feel they're going to need.

Richard MacPherson: The offtake agreements are the next step, to answer your question, in the rejuvenation side of our business. Now that we've proved that we can do it and we're doing the analytical work on a one-on-one basis, the next step will be to get the offtake agreements in place that will allow us to move forward with the construction of these facilities.

Speaker #3: So the offtake agreements are the next step, to answer your question on the rejuvenation side of our business. Now that we've proved that we can do it and we're doing the analytical work on a one-on-one basis, the next step will be to get the offtake agreements in place that will allow us to move forward with the construction of these facilities.

Rob Brown: Okay. The last question's on the new ion exchange product line. You gave some color on the market opportunity. Is that market sort of the similar customer base, or would this be a utility customer base? Just maybe help me understand the customer base that you're going after there.

Speaker #4: Okay, and then the last question's on the new iron exchange product line. You gave some color on the market opportunity. Is that market sort of the similar customer base, or would this be a utility kind of customer base? Or just maybe help me understand the customer base that you're going after there?

Richard MacPherson: Yeah, actually it's a totally different market. We're very excited about it. We've had great results with this new product that we've helped to bring to market. It is a, you know, multi-hundred million dollars opportunity. We're focused on the power plant side of it at this point. We expect to be able to expand as well. You know, we've yet to talk about the water treatment services side of our business. I think that will show a substantial growth this year, in real revenues, adding to that first $1 million plus of business that we've booked to date. I really think that, and we're now looking to hire specialists to represent us in the field, on that particular product line.

Speaker #3: Yeah, actually, it's a totally different market. We're very excited about it. We've had great results with this new product that we've helped to bring to market.

Speaker #3: And it is a multi-hundred-million-dollar opportunity. We're focused on the power plant side of it at this point, but we expect to be able to expand as well.

Speaker #3: And we've yet to talk about the water treatment services side of our business. And I think that will show substantial growth this year in real revenues, adding to that first million-plus of business that we've booked to date.

Speaker #3: So, I really think that—and we're now looking to hire specialists to represent us in the field on that particular product line. But I've also been looking at adding others to our team to move our general water treatment materials into the market.

Richard MacPherson: I've also been looking at and adding others to our team to move our general water treatment materials into the market. I really think that that's one of our faster growing aspects in 2026 in terms of adding real revenue to the company.

Speaker #3: So, I really think that that's one of our faster-growing aspects in 2026, in terms of adding real revenue to the company.

Rob Brown: Okay, great. Thank you. I'll turn it over.

Speaker #4: Okay, great. Thank you. I'll turn it over.

Richard MacPherson: Thank you.
