Following an improved year of financial performance in 2022, we started off the new year on very solid ground. Both the APC and FUEL CHEM business segments reported higher revenues, which resulted in a 32% increase in consolidated revenue from the prior year to $7.3 million. We maintained a conservative cost profile, narrowed our losses, ended the quarter with total cash and investments of nearly $34 million, with no long-term debt. Our backlog was $7.6 million, down slightly from $8.2 million at year-end, including the $5.2 million of new 2023 orders announced in February. We continue to pursue a global sales pipeline of $50 million-$75 million, consisting of a variety of projects and end markets. To that end, during the quarter, there was a promising development with respect to new U.S. government emissions control legislation that we have been discussing with you for quite some time. We believe that this ruling can provide a long-term uplift for our APC product line, and I'll discuss this development shortly. Bill Decker, our recently appointed Vice President of Water and Wastewater Treatment Technologies, has been very active in getting up to speed on the business, leveraging his industry network and helping to drive this segment towards commercialization. To that end, we expect to commence our first on-site demonstration using our small-scale Dissolved Gas Infusion system at an aquaculture setting in the United States late in the second quarter or early in the third. The deployment is scheduled to last approximately three months, with the objective of improving the productivity and efficiency of the customer's operation through the use of optimized high levels of dissolved oxygen. In addition to this opportunity, we are also pursuing additional demo opportunities across various end markets, preparing end-market-specific marketing materials, and continuing the development of our engineering design standards for DGI delivery systems of different capabilities. Our FUEL CHEM business segment had a strong Q1, with revenue increasing to $3.7 million from $3.3 million in the same period last year. An overall increase in energy demand year-on-year positively impacted coal-fired dispatch in regional areas where we have our programs installed. We continue to develop new marketing strategies to reach key decision makers at all domestic coal-fired utilities to reintroduce our FUEL CHEM program benefits, including lowering the cost of dispatch by offering fuel flexibility, extending facility life, and improving overall facility profitability, and structuring a program that is active only when the unit owner wants to capitalize on high energy demand and related high unit capacity factor opportunities. With respect to international opportunities for the FUEL CHEM segment, we are continuing 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. We recently executed a one-year extension to the program that we currently have in place at one facility. We do believe that political pressure is building in favor of the 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. As we look out to 2023, we currently expect that FUEL CHEM revenues will decline modestly from 2022 levels, due primarily to a reduction in program utilization levels at our primary accounts from the high levels experienced in 2022, and to the elimination of one account due to plant closure. For the APC segment, revenue rose to $3.6 million from $2.2 million in last year's Q1, due largely to the timing of project bookings and project execution against our backlog. During the quarter, we either commenced or continued emissions control projects that included our SCR, SNCR, and ULTRA technologies. Based on our Q1 performance, the effective backlog that we have in place today, and the visibility that we have into potential new orders, we are confident that our APC revenues for 2023 will well exceed 2022 APC revenues of $10.6 million. A potential source of new business for the APC segment for 2023 and years beyond was further clarified in March of this year, when the US EPA issued a rule finalizing requirements that obligate 23 states to reduce emissions of nitrogen oxides from power plants and certain industrial facilities. This updates the Cross-State Air Pollution Rule while meeting the Good Neighbor requirements of the Clean Air Act. These CSAPR revisions could impact utility industrial resources requiring additional NOx control starting as early as 2023 for utility units and 2026 for industrial units. We believe that this new legislation could drive new orders over the next several years for our selective catalytic reduction systems for higher reductions of NOx, selective non-catalytic, catalytic reduction systems or SNCR technology for units that require incremental NOx control, and for our ULTRA systems, which provide a safe reagent for SCR installations. Although it is difficult to quantify the impact at this time, I can definitively say that we are having more meaningful and directed conversations with potential customers since the ruling was passed in March. Given the respective outlooks for both the APC and FUEL CHEM segments, we continue to expect that total revenues for 2023 will improve to between $27 million and $32 million, up from $26.9 million in 2022. This base case outlook excludes any material contributions from DGI, as we are still in the early stages of commercialization and any significant contributions to APC from the recent EPA ruling in March. In closing, I want to again thank the Fuel Tech team for their continued hard work and dedication as we work each day diligently to satisfy our customers' requirements and plan for the development and expansion of our water technology initiative. I also want to thank our shareholders and other stakeholders for their continued support as we strive to grow our business as a global supplier of technologies for clean air and pure water. With that said, I'd like to turn the discussion over to Ellen. Ellen, please go ahead. Thank you, Vince. Good morning, everyone. For the quarter, consolidated revenues rose 31.7% to $7.3 million from $5.5 million in last year's Q1, with both our primary business segments recognizing higher revenues. APC segment revenue increased to $3.6 million from $2.2 million in last year's Q1, reflecting the execution of orders reflected in our year-end backlog and bookings received during Q1 of 2023. FUEL CHEM product line revenue rose to $3.7 million from $3.3 million, due primarily to improved dispatch levels for power generation facilities that use our program. Consolidated gross margin for 2023 Q1 dropped slightly to 38.5% of revenues from 41.4% of revenues in last year's Q1. This decline can be attributed to lower APC segment growth margins, which were 27.1% in Q1 of 2023 as compared to 35.2% in Q1 of 2022. The reduction is being driven by project and product mix. FUEL CHEM margins remain strong, improving to 49.4% from 45.5% in the prior year Q1 due to increased top-line performance. Consolidated APC segment backlog at March 31, 2023 was $7.6 million, down from $8.2 million at December 31, 2022. Backlog at quarter end included $6.1 million of domestic delivered project backlog and $1.5 million of foreign delivered project backlog, as compared to $6.3 million of domestic project backlog and $1.9 million of international project backlog as of December 31, 2022. We expect that $7.3 million of the current consolidated backlog will be recognized in the next 12 months. SG&A expenses rose slightly to $3.2 million from $3.1 million in last year's Q1. However, as a percentage of revenue, SG&A in the 2023 Q1 declined to 45% from 55% in 2022 Q1, reflecting significantly higher consolidated revenue. For the full year 2023, we expect SG&A expenses to range between $13 million and $14 million as we invest in resources to support current business initiatives and in the development of our DGI technology operations. Research and development expenses for Q1 were steady at approximately $220,000, primarily attributable to timing of execution on current project initiatives. As Vince indicated, we are preparing to participate in our first on-site demonstration using our small-scale Dissolved Gas Infusion system and are pursuing several other opportunities and will adjust R&D spending as needed for the commercialization and development of our DGI technology. Our operating loss declined to $658,000 from $984,000 in last year's Q1, primarily driven by higher total revenues and a relatively stable year-on-year expense profile. As we discussed last quarter, we continue to take advantage of the favorable interest rate environment and as of March 31, 2023, have invested approximately $30 million and held to maturity debt securities and money market funds. This generated $339,000 of interest income in Q1, compared to virtually no return in the same period last year. We estimate that interest income for 2023, barring any unusual cash deployments to grow the business, will be approximately $1.2 million. Our net loss for the quarter narrowed to $414,000 or $0.01 per share, compared to a net loss of nearly $1 million or $0.03 per share in the same period one year ago. Adjusted EBITDA loss was $569,000, compared to an adjusted EBITDA loss of $868,000 in the same period last year. Our financial position is amongst the strongest in our history. As of March 31st, we had cash and cash equivalents of $15.7 million and short and long-term investments totaling $18.1 million. Working capital was $30.2 million or $1 per share. Stockholders' equity was $44.6 million or $1.47 per share, and the company had no debt. Cash provided by operating activities at March 31st was $1 million, driven primarily by the timing of AR collections, compared to cash used in operating activities of $1.7 million at March 31st, 2022. I share Vince's optimism about our future and look forward to keeping you all apprised of our progress and developments. Ellen, thank you very much. Operator, I would now like to go ahead and open the line for questions. Thank you. We will now be conducting a Q&A session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. Your first question comes from Sameer Joshi with H.C. Wainwright. Please go ahead. Thanks. Good morning, Vince, Ellen. Really nice results. Congrats on the performance. Thank you, Sameer. The first question is just in terms of APC backlog as well as the pipeline that you see in front of you. Do you have an estimation of what kind of gross margins you would expect from it, given that the current quarter gross margins were lower year-over-year? Yeah, I would still expect, even though we did have a little bit of a lower gross margin, particularly on the APC segment in Q1, I still expect APC segment gross margins to be between 30% and 35% on a full year basis. That would be our target for that business segment. Now very often, Oh, go ahead, Sameer, please. Yeah, yeah. No, I was just going to ask, like was there something extraordinary or one time in the current quarter, or rather 1Q 2023, costs of goods sold or something? Actually, no. What we do experience from project to project is that certain technologies are prone to realize a different gross margin levels, if you will. Then as we execute out in those projects from quarter to quarter, we will have a mixed impact on the APC gross margin depending on what technologies are actually being executed during that quarterly period of time. Nothing exceptional going on. Just during Q1, we had execution on APC projects that just happened to have slightly lower gross margins. Simple as that. Got it. Got it. Got it. The, just digging a little bit deeper. I think you said new orders were $5.2 million during the quarter and the backlog decreased by around $600,000. I think most of the orders that you received in the quarter, or at least, there was a conversion of orders during the quarter. Just wanted to see if these orders were short-term, quick turnaround or was this something that was already in the backlog that was converted? Right. The projects that we actually announced, the $5.2 million that we announced during Q1, it did include some projects that were technically booked before the end of 2022. We typically look to aggregate before we announce. The $5.2 million did include some projects that were booked prior to the end of 2022. Relative to the timing of execution on backlog as Ellen noted, I think of the backlog that we have out there today, the great majority is going to be basically executed upon within this next 12-month period of time. Obviously we will be looking to rebuild backlog as we move throughout 2023. Good. Thanks for that. On the FUEL CHEM side, I guess I know the answer, but will you clarify how the revenue was higher quarter-over-quarter, year-over-year, even though one of the facilities was not included anymore? Right. From year to year, what we find is that our customers will take their outages or they'll take downtime, due to demand reasons, at various points in time. From year- to- year, that will indeed vary. The performance we did have in Q1 of 2023 was a little bit of a surprise to us in terms of the magnitude of revenues that we did derive. As it relates to comparison to 2022, higher demand, higher uptime on our base units, and on our largest units. Okay. Okay. The outlook, I think you mentioned it will FUEL CHEM will be slightly lower year-over-year because of that one unit, not in the picture anymore. That is correct. On an overall basis in 2022, we had extraordinary uptime and demand for our program on the units that we were actually running on for 22. We're just not necessarily expecting that to recur for the full year of 23. It could, but that would be an extraordinarily optimistic outlook. Understood. Okay. A clarification on the outlook for the SG&A. I think Ellen said $13 million-$14 million. Just wanted to confirm that this is a GAAP outlook or is it just a non-GAAP without stock-based comp and other stuff? It's GAAP. It is a GAAP outlook. It is a GAAP outlook. Yes. Okay. On the DGI front, how much cost do you expect to incur in the Q2 and Q3 timeframe for this demo or on-site demo? I would probably say in the range of $100,000, Sameer. Approximately. Okay. Yes. Okay. It's not significant. How do you have any level of confidence or visibility in terms of, you guys are really looking for it, and, if it works, they will actually place orders for this unit? What is the comfort level there? I'd say that we're extremely confident that we're going to have DGI perform very well for this particular customer's application. I think we have a high level of confidence. Great. Great. Good job on investing and getting interest. I think that's such a good line. Also congrats on a positive cash flow quarter. That's all from me. Thanks, and good luck. Sameer, thank you very much. Once again, if you would like to ask a question, please press star one on your telephone keypad. Okay, there are no further questions at this time. I would like to turn the floor over to Vincent for closing remarks. Thank you very much. As I had noted, we are pleased with our start to 2023, with a good Q1 of performance for us. Our objective obviously is to generate operating profit as a company as a whole, and we are moving positively in that direction. I want to again, thank the Fuel Tech team and thank all of our shareholders and stakeholders for their support of our company. Thanks to everyone, and have a great day. This concludes today's teleconference. You may disconnect your lines at this time, and thank you for your participation.
