Greetings, and welcome to the Fuel Tech, Inc. Fourth Quarter and Full Year 2023 Financial Results Call. [Operator Instructions]. As a reminder, this conference is being recorded. I would now like to turn the conference over to your host, Devin Sullivan, Managing Director ofthe Equity Group. Thank you. You may begin.
Thank you, Melissa. Good morning, everyone, and thank you for joining us today for Fuel Tech's 2023 Fourth Quarter and Full Year Financial Results Conference Call.

Thank you, Devin. Good morning, and I'd like to thank everyone for joining us on the call today. We were pleased with our business progress along several fronts in 2023. Total revenue of $27.1 million was within our previous guidance range and represented our highest annual revenue level since 2019. Our APC business segment performed well, reflecting more than $8.3 million of new project awards during the year, and we ended the year with a backlog of $7.5 million at December 31, 2023. Further, we were pleased to announce the additional $2.1 million in new contract awards yesterday. We completed a successful trial of our dissolved gas infusion technology in an aquaculture setting, and we believe that we are well positioned to commercialize DGI in 2024. And lastly, we continue to maintain a conservative cost profile with SG&A expenses up modestly from 2022 levels and ended the year in a strong financial position with $33.4 million in cash and investments and no long-term debt. We are most heartened by the progress we have made in our DGI business initiative in 2023. Last month, we announced the publication of a white paper that details the benefits of deploying DGI for oxygen injection at a shrimp farm in the United States. As a reminder, our DGI technology involves the efficient transfer of high concentrations of gas into a body of water through a patent saturator and a patent-pending injection array to drive chemical or biological reactions such as for wastewater treatment, odor control and PH adjustment or for process improvements in industrial applications or in this case, aquaculture. Specifically, the use of DGI at this location increased shrimp production compared to traditional aeration methods and contributed to likely health improvements. Demand for shrimp is increasing globally and inland shrimp farming is an important source to help meet the growing demand in a safe and sustainable manner while reducing overfishing of the marine environment and lowering the overall carbon footprint by reducing transportation costs. By deploying DGI, producers now have an opportunity to improve stock health and yields while achieving more efficient operations immediately adjacent to their customer locations. At present, we are utilizing DGI to deploy oxygen into bodies of water. However, we believe that DGI can be applicable for other guesses as well, such as CO2 and ozone. DGI's benefits include the precise control of dissolved oxygen levels for all process applications and ability to extend plant capacity without major capital expansion or capital outlay, order reduction and minimal bubble formation for extended residence time. We believe that DGI can be applied across several end markets, including pulp and paper, food and beverage, chemical and petrochemical, water and wastewater treatment, horticulture and aquaculture. As a follow-up to the publication of our DGI white paper, we presented our technology and favorable findings from our aquaculture demonstration at the Aquaculture America 2024 Conference last month. This annual conference provides members and participants with the opportunity to stay current with technical advancements and inspect the latest in products and services in the aquaculture industry. In recent months, in part driven by the interest generated after publishing and presenting our demonstration results, we have received a notable increase in inquiries regarding our DGI technology from potential customers in multiple end markets, including municipal odor control, pH control for municipal and industrial applications, agricultural applications and additional aquaculture applications. We are currently in negotiations with potential customers regarding on-site demonstrations of DGI, and we are targeting to sign our first commercial contract for DGI in 2024.Lastly, to further expedite the introduction of DGI into end markets, we have recently hired a former water and wastewater treatment executive on a consulting basis. This individual is well experienced in the application of dissolved gas technologies, and we look forward to his contributions over these next several months. Let's now please spend a few minutes discussing our FUEL CHEM and APC business segments. As we had expected, revenues for our FUEL CHEM segment declined from 2022 levels due to the effects of warmer weather across the U.S., which impacted overall demand and related unit dispatch. However, segment gross margin was essentially unchanged for the year and remain at historical levels. Our base FUEL CHEM unit count remains intact as we enter 2024. And for the first time in a few years, I'm very pleased to say that we are currently pursuing multiple additional FUEL CHEM development opportunities, which could provide incremental revenue contribution in 2024 and beyond. These opportunities are for both coal and biomass-fired boilers. For 2024, excluding any material incremental revenue from new business development activities, we would expect that FUEL CHEM revenue would remain at parity with 2023.With respect to international opportunities for the FUEL CHEM segment, we continue to follow the opportunity to expand the provision of our chemical technology in Mexico via our partner in that country to address the emissions created by the burning of high sulfur fuel oil, which is being undertaken without the necessary environmental remediation and at the expense of the health of surrounding communities. In 2023, we executed a 2-year extension to the program that we currently have in place at 1 facility. With the upcoming presidential election in Mexico in June of this year, we believe that political pressure is building in favor of our implementation of our FUEL CHEM program at additional facilities in this country. Our partner is currently in discussions with the state-owned utility CFE regarding the application of our technology at several units. Now turning over to our APC segment. We benefited in 2023 from the continued adoption of our Ultra SCR, SNCR and FTC emissions control solutions at natural gas and coal-fired units in the U.S., Europe, South Africa and Pacific Rim. Independence of the potential impact of favorable regulatory outcomes, which I will discuss here shortly, will remain well positioned to take advantage of current industrial end market trends, which include plant capacity expansion across several industries, the incentivized use of small turbines to replace traditional less clean power generation, the development of the biocarbon industry, the continued emphasis on decarbonization on a global basis and the focus on using our ULTRA system as a safe source of ammonia for SCRs at hospitals and universities across the U.S. On the regulatory front, we continue to monitor progress related to the adoption of the U.S. EPA's Cross-State Air Pollution control rule to meet the good neighbor requirements of the Clean Air Act, which we believe can be a potential catalyst for APC growth in 2024 and for the remainder of this decade as utility and industrial customers explore ways to further reduce NOx emissions. We have, in fact, received and responded to several requests for budgetary proposals as customers prepare to address the upcoming compliance requirements as part of their capital budgeting requirements for 2024 and beyond. As discussed on previous calls, the rule currently obligates 23 states to reduce emissions of nitrogen oxides from power plants and certain industrial facilities to limit their impact on downward states. The ultimate timing of the effectiveness of the rule is uncertain because several up win effective states and sources have challenged the efficacy of EPA's proposed regulation in multiple cohorts and stays of the effectiveness of the rule have been issued for many upwind states. Last month, oral arguments were presented to the Supreme Court by both parties, and we will closely monitor the potential impact of the Supreme Court's ruling on whether to save the rule for all states when it is issued later this year. In addition to the good Neighbor rule, we are also watching the progress of EPA's rule for large municipal waste combustors, which is independent of the good Neighbor rule. This rule reduces the nitrogen oxide emissions requirements for large municipal waste combustor units. Fuel Tech has had a long history of assisting this industry in meeting their compliance requirements, and we have had discussions with customers in this segment to support them in their compliance planning. The municipal waste combustor rule is currently in a public comment period with compliance deadlines expected sometime in the next 3 years. Based on our effective backlog at year-end, the business development activities we are pursuing and our previously noted expectations for FUEL CHEM, we expect that total revenues for 2024 will exceed the total revenues recognized in 2023 of $27.1 million, and we will provide further guidance as we move throughout 2024. This base case outlook excludes any material contributions from DGI as we are still in the early stages of commercialization, any significant contributions to APC from the above referenced EPA regulations and the impact of material business development activities for FUEL CHEM. Now in closing, I want to take -- to thank the Fuel Tech team for their contributions to the improvement of our business in 2023. It is their continued hard work, passion and dedication that drive our ability to be successful. Additionally, I thank our shareholders for their continued support. We expect that 2024 will be an important year in the growth and evolution of Fuel Tech, and we look forward to keeping everyone apprised of our progress. With that said, I would now like to turn the call over to Ellen to talk about our financial statements. Ellen, please go ahead.
Thank you, Vince, and good morning, everyone. The primary takeaways from 2023 were improved total revenue, margin maintenance, a continuing focus on cost containment within the larger framework of building out our DGI business and a remarkably resilient balance sheet that allowed us to enter 2024 in a strong and secure financial position. We accomplished all of this while navigating some industry headwinds in our 2 primary business segments. I'll start off today by reviewing our fourth quarter results. For the quarter, consolidated revenues declined to $6.3 million from $7 million in last year's fourth quarter, reflecting declines in both the APC and FUEL CHEM segment from the prior year period. APC segment revenue marginally decreased to $2.8 million from $2.9 million due primarily to the timing of execution on projects and services during the quarter. The Fuel CHEM segment revenue declined from $4.1 million to $3.6 million, mainly due to an expected decrease in dispatch electrical generation demand from the very high levels experienced in 2022 and changes in product and fuel usage. Consolidated gross margins for 2023 fourth quarter was 51% of revenue, a significant increase from 43% in the fourth quarter of 2022, reflecting increased APC segment gross margin of 55%, up from 35% in the same quarter a year ago. This higher gross margin for APC can be attributed to a change in projects and product mix. Fuel CHEM segment gross margin remained essentially unchanged at 48%, consistent with historical performance. Consolidated APC segment backlog on December 31, 2023, was $7.5 million, up from a backlog of $5.6 million at September 30, 2023, and down slightly from backlog of $8.2 million at December 31, 2022. Backlog on December 31, 2023, included $2.6 million of domestically delivered project backlog and $4.9 million of foreign delivered project backlog as compared to the $3.7 million of domestic project backlog and the $4.5 million of international project backlog at December 31, 2022. We expect that $7.4 million of the current consolidated backlog will be recognized in the next 12 months. SG&A expenses increased to $3.7 million from $3.1 million in last year's fourth quarter, reflecting the timing of employee and employee-related expenses. As a percentage of revenue, SG&A in the 2023 fourth quarter increased to 58% from 44% in the 2022 fourth quarter. Research and development expenses for the fourth quarter rose to $367,000 from $179,000 in the same period a year ago, mainly attributed to continued investments in water treatment technology and more specifically, our DGI technology. Our operating loss was $801,000 compared to $250,000 in last year's fourth quarter, reflecting a reduction in overall revenue, a shift in margin contribution from product mix and higher operating expenses for the quarter. We continue to take advantage of the favorable interest rate environment. And as of December 31, 2023, have invested more than $30 million in held-to-maturity debt securities and money market funds. This generated $322,000 of interest income in the fourth quarter and $1.3 million of interest income for 2023, up from just $200,000 in 2022. Our net loss for the quarter was $539,000 or $0.02 per share compared to a net loss of $402,000 or $0.01 per share in the same period 1 year ago. Adjusted EBITDA loss was $646,000 compared to an adjusted EBITDA loss of $263,000 in the same period last year. Moving to results for the full year 2023. Consolidated revenue rose to $27.1 million from $26.9 million in 2022, reflecting a 27% increase in our APC segment revenue, offset by a 17% decline in the FUEL CHEM segment. As previously mentioned, the increase in APC segment revenue is attributed to the timing of project execution and new orders and a 50% increase in our ancillary product line revenues. The FUEL CHEM segment revenue decreased for the year was driven by decreased unit dispatch demand and unforeseen plant outages experienced in the second quarter of 2023. Consolidated gross margin remained flat at 43% compared to last year, reflecting an increase in the APC segment gross margin, offset by a slight decrease in the FUEL CHEM gross margin. APC segment gross margin was primarily -- the growth was primarily due to product and project mix. SG&A expenses for 2023 increased by 4% to $12.8 million from $12.3 million in 2022, which fell within the low end of the forecasted range. We continue to prioritize our strategic investments and resources to support current and upcoming business initiatives while maintaining prudent cost control. For 2024, we expect SG&A expenses to range between $13 million and $13.5 million. Research and development expenses were $1.5 million for 2023 compared to $895,000 in 2022. As Vince discussed, our investment in commercializing our DGI technology is a primary focus for the company. Strategic expenditures in this area will continue throughout 2024. Operating loss was $2.7 million for the 2023 compared to a loss of $1.5 million in 2022, reflecting the change in mix of segment revenue and higher operating expenses. Net loss for 2022 was $1.5 million or $0.05 per diluted share compared to a net loss of $1.4 million or $0.05 per share in 2022. Adjusted EBITDA loss was $2 million in 2023 compared to an adjusted EBITDA loss of $909,000 in 2022. We generated nearly $700,000 in cash from operations in 2023 as compared to a use of cash of $4.1 million in 2022. Lastly, moving to the balance sheet. Our financial condition remains strong. As of December 31, 2022, we had cash and cash equivalents of $17.6 million and short and long-term investments totaling $15.8 million. In 2023, our largest use of cash was the incremental investment of $6 million in debt securities to drive a sustainable long-term financial profile. Working capital was $32.6 million or $1.08 per share. Stockholders' equity was $43.7 million or $1.44 per share, and the company continues to have no outstanding debt. We remain confident in our ability to fuel our growth initiatives, pursue new products and market opportunities and maintain our strong financial position, which we view as important as an important competitive advantage. To reiterate Vince's earlier comments, we are pleased with our results and remain optimistic about our opportunities in 2024 and beyond. I'll now turn the call back over to Vince.
Ellen, thank you very much. Operator, I think it's time to open the line for calls now.
[Operator Instructions]. Our first question comes from the line of Amit Dayal with H.C. Wainwright.
So it looks like DGI is going to be a big focus for you this year. My one question is how are these potential customers finding out about DGI. Can you just give us a sense of what you guys are doing in terms of just getting in front of this audience.
Right. So we -- over this past 6 months, we've definitely enhanced our marketing efforts. And as I just noted, our presentation at Aquaculture America was actually our first presentation at a water and wastewater treatment conference, and we received some very favorable impact from the result of that body of work. So my comment would be we are increasing our exposure to end markets. We really needed to have something to go ahead and put out there publicly that we can support as part of our market reach out and the successful demonstration that we did have in the aquaculture application, affords the opportunity to start to go a little bit more public with DGI and its capabilities. And so my expectation is that is going to continue. We are going to have more of a, call it, a public phase for DGI, but it also needs to continue to be supported by specific favorable actions from end results of that technology, if you will. So we are going to do additional demonstrations. We are going to do white papers on those additional demonstrations and put those results out publicly as well. So again, a high-level answer. We are going to be out there more publicly with DGI in 2024 and beyond.
Understood. And then the OpEx guidance you provided for the year, does that all include some of the marketing and sort of business development efforts? Or will that potentially be a little bit more additional costs to your normal sort of operating activities.
Yes. Right now, the range that Ellen provided $13 to $13.5 million does include a nice uptick in additional spending related to DGI marketing efforts. As we've discussed our investment in DGI with this past handful of years, we've been very measured in how we've been investing as we see the opportunity to invest based on successes, we'll go ahead and enhance that investment in those activities. So right now, I would tell you that the range Ellen gave does include a nice increase in expenditures for DGI marketing efforts. If we feel as though we need to do more prospectively, we'll share that with you on future calls.
Understood. Maybe just last one on the APC and FUEL CHEM businesses. should we expect the second half to be stronger for those segments or sort of evenly spread throughout the year? Just on the press release and some of your commentary. Maybe the second half looks like it could be more heavier in terms of revenue versus first half of the year?
As a general statement, I would say, yes, that is correct. Based upon the way we see things right now, we would expect a stronger second half than first half of the year.
Our next question comes from the line of William Bremer with Vanquish Capital Partners.
I want to specifically target your -- the Air Pollution Control segment, the APC segment. Regarding our product offering, how would you rate that?
I think our product offering for these technologies is best-in-class. For what we put out into the marketplace for SNCR and SCR technologies and Ultra as well, they're best-in-class. We -- and actually, for Ultra, there is no competitive product in the marketplace today domestically.
And I completely agree with you. I mean, us, I've been with in having a material stake in this company for north of 7 years. My concern is on the sales front and the bookings, Your senior VP of sales has been with you over 25 years. I mean, 25 years is an enormous amount of time. You voiced about the regulatory front and the EPA and the good Neighbors Act that be a major catalyst for us going forward. At what point does the Board have to make a change here to start bringing in some confident individuals to ramp up the sales, utilize the balance sheet and hire some executive VPs to go after the submissions opportunity that's in front of us.
So to specifically address your question, Fuel Tech as a company has a lot of longer tenured employees. I'm at 24 years myself. And so I would put myself in the category as a lot of well-experienced folks with Fuel Tech that I believe are still doing a pretty darn good job, okay? So specifically on the APC side of the equation, as you note, what's potentially out there related to regulatory opportunities, I'll tell you right now that there is no one that is better positioned to capitalize on those opportunities should the regulatory requirements be officially put in place in a way that drives business because I can tell you right now, I've seen that the proposals and work that we've put out to the utility customer base in this country that supports the work that we would be doing if we had a firm regulation in place. So I have every confidence in the world, Bill, and you and I have discussed this previously, with the team that we have in place, and I am Chairman of the Board, so I'll speak on behalf of the Board as well. We're confident in the team that we have in place to be able to capture these future opportunities that are potentially out there for us. If that wasn't the case, Bill, we'd be making dramatic changes. As simple as that. Simple as that.
I hope you're right. I haven't seen a book to burn ratio over 1.5 in years in this segment.
I don't disagree with you there. The end markets, particularly on the utility segment, have been a little shallow over these past several years. Fortunately, we've been supported by industrial market activity, which in the absence of anything that happens regulatorily, that base business level is still going to be there for us prospectively. It's the upside that we're talking about, and I think we're very well positioned to capture the upside.
My second question, other than yourself stepping in pretty much every year consistently, and I appreciate that as well as my fellow shareholders. I have not seen any Form 4 open market purchases from anyone else on the board for years or your CFO, your division heads, et cetera. If the company is making a change and we're selling below a tangible book, as you articulated, and we are flush with cash, okay? When is the management team going to step forward here and align themselves with current shareholders?
It's a good point, Bill, as you stated. I've been out there buying, there's been at least one other high-level officer of the company that has been out there buying over these past few years. We only have 3 reportable employees that we form for as we sit here today. So there is some other activity that the public world does not see relative to purchases. All I can say is that it's difficult for me to go ahead and mandate that, whether it be the Board or the leadership team difficult to mandate that they take their personal situations and further invest in Fuel Tech. The Board and the employees of this team are already well vested in Fuel Tech. I can definitely make that statement, honestly, and clearly. I think you'll see some additional purchases from the leadership team and our Board in the future. I just can't tell you when. But I can tell you, from my perspective, I have been a supporter and I will continue to be a supporter from that perspective.
I truly do. I would welcome to see some additional sales hires. I think that would be a good use of capital versus a dividend or share repurchase agreement. I think we need to drive top line sales restructuring has been performed about less few years, and now it's time to grow the top line. So I would echo and my fellow shareholders, and I would hope the Board and yourself decide to start hiring some additional sales personnel and the ones that aren't producing have to go at this point.
Understood, Bill. I appreciate your commentary as always, and I can tell you that we review every one of this company on an annual basis relative to performance. But as I said, I am very confident that we are well positioned to take advantage of opportunities that are going to come our way.
Our next question comes from the line of Jim McIlree with Dawson James.
I just wanted to make sure I heard your comment correctly regarding the APC revenue this year. That assumes no impact from a potential favorable good neighbor ruling. Is that correct?
That is correct.
And so -- and I know there's a lot of different end cases on the ruling. But can you kind of bracket what you think that might do for APC over a couple year time period? How big of an impact do you think it might have over a couple of years?
Jimmy, it's quite favorable. We went through approximately 9, 10 years ago, a scenario whereby the effectiveness of regulation had a very favorable impact on the company as well. But what I can say is this, we have $50 million plus in budgetary quotes out to utilities in this country to help to assist them with compliance. The numbers, it's greater than that. And it's -- everything can't be done at once, obviously. So this would be implemented over a, I'll say, a 3- to 5-year time horizon approximately, but it's a magnitude over the APC revenue that we've generated over these past 3 to 4 years. It's a material impact on our company. As I said, it's something that we've dealt with historically. We would love to be able to address those needs again.
Understood. That's helpful. And then my second question is on the -- you talked about the initial DGI contract this year. Can you be a little bit more specific on timing, first half, second half? And just how big can these contracts be these initial contracts? Are we talking sub $1 million? Or are we talking greater than $1 million.
Right. So on your first question, I would look at second half of the year from a timing perspective. And then on your second question, I'd probably expect the first system sales that we'll see that they're going to be sub 1 million and a lot larger than $1 million. Our smaller systems are anywhere on the $100,000, $200,000 range, assuming it would be a capital sale. Some of the larger scale systems are indeed going to potentially exceed $1 million completely depends on the magnitude of the process environment that we're looking to treat. But when I look at something commercially happening this year, I think we're probably seeing something more on the smaller side than on the larger side.
Our next question comes from the line of Marc Silk with Silk Investment Advisors.
So let's go and stay stick with the -- good Neighbor rule. This -- you said you've received a bunch of requests, et cetera. Are these mostly from downwind states or up wind or it's a mix?
I would say predominantly up wind, but some downwind. Primarily upwind folks, again, looking at their potential range of outcome given what way the regulatory rule falls.
Correct. Yes. And then so like on the $50 million plus of, let's just say, potential there, I know it could be a lot more. Is that like a 50-50 mix?
I'd say it's -- it would be more in favor of UpWind.
[Indiscernible] point. Okay. And then the -- on the DGI, you talked about multiple end markets. You mentioned a bunch of things like municipalities, et cetera. Let's say money was an object that you had an unlimited budget, unlimited cash. Where would you aggressively be putting money based on what you've seen up to now? Or is it too early to kind of say this is more of a hypothetical just so we can kind of see where maybe the biggest growth can come from over the next few years.
Right. I -- to be honest, I would say that it's premature for me to say where we would invest the majority of that capital, assuming we had end pockets, if you will. It's premature to say. We're looking for what I would call near-term opportunities for success of the technology to form building blocks for whatever comes prospectively from that. We need to build the success building blocks. The demonstration we did last year was one of those. We need more of those end markets to prove out the viability of the technology. And then once we have a little bit more of that information, we can then better assess where our investment dollars are going to be better spent relative to approaching one end market over another.
And as far as municipalities, what are some of the areas they are looking at? I know you mentioned it earlier, but I can't read my notes here.
One of the ones we're looking at here near term is actually an odor control application for a municipal water lift station. That's a huge problem for them, but there's other applications for municipalities that we'll be able to address as well. This one for odor control is an immediate requirement for us.
Our next question comes from the line of Pete Enderlin with MAZ Partners.
I just have a couple of questions. You've mentioned a lot of different opportunities for the DGI technology. One that you didn't mention, and I don't know if it's actually valid or not, and that is related to 3M. Last June, 3M agreed to pay $10.3 billion over 13 years for the remediation of forever chemicals and drinking water. That's a lot of money, obviously. And so the question is, will or could DGI play a role in that process? I mean I'm sure that there's some filtration and other stuff going on to remove those chemicals, but would DGI enhance that process? And is that a valid opportunity?
As we look at it right now, Pete, DGI would not have a direct impact on PFAS PFO forever chemicals. It's -- to your point, it's a very, very, very widely watched area today on a global basis. And the EPA is coming out with regulatory requirements and guidance that I don't think anyone can achieve at this point in time because no one has all the answers. It's something we're going to watch closely. Again, to your point, to see if DGI can help enhance certain whether it be chemical-related processes or otherwise that could address the forever chemical issue. But as of today, it's not something where we're relying on that end market is something that we're focusing on right now. But it is something that we'll watch.
And then one for Ellen. The SG&A expense in the fourth quarter was $3.7 million versus $3.1 million. And the press release says to the timing of employee and employee-related expenses. Can you just elaborate on that a little bit? Was there anything sort of nonrecurring in there? Because obviously, if you annualize $3.7 million, it's a lot more than your projected level for this year.
Correct. There were some employee and employee-related expenses that last year were spread out over the last 6 months of the year. And in 2023, just happened to all hit in Q4.
Okay. So it's nothing specifically identifiable as nonrecurring, just basically as it says, the timing.
Correct. It's just timing.
Ladies and gentlemen, there are no other questions at this time. I'll turn the floor back to Mr. Arnone for any final comments.
Thank you, operator. Once again, I'd like to thank everyone who participated in the call today. I'd like to thank all of our shareholders. And of course, the entirety of the Fuel Tech employee team. As both Ellen and I noted, 2024 is indeed a critical and pivotal year for Fuel Tech. And as we move throughout the year, we are excited, and we look forward to having further discussions with everyone at later points in time this year. Thanks to everyone, and have a great day.
Thank you. This concludes today's conference. You may disconnect your lines at this time. Thank you for your participation.
