For decades, the company has served utility and industrial customers globally with its Air Pollution Control (APC) and FUEL CHEM technologies, addressing critical needs like reducing harmful nitrogen oxides (NOx), particulate matter, and improving boiler efficiency. This history of innovation and problem-solving has positioned Fuel Tech as a player in the environmental technology landscape, albeit one operating within a competitive field alongside larger, more diversified entities. The company's strategic journey has involved adapting to evolving market demands and regulatory environments. A notable shift included the planned suspension of its China APC business, initiated in 2019, to streamline operations and focus resources on more promising global opportunities. More recently, Fuel Tech has embarked on a strategic expansion into the water treatment market with its Dissolved Gas Infusion (DGI) technology, seeking to leverage its engineering expertise in a new, growing sector. This blend of refining its core offerings while exploring adjacent markets defines Fuel Tech's current strategic posture. Fuel Tech's competitive positioning is shaped by its specialized technological offerings and operational model. In the APC space, it competes with larger players like Babcock & Wilcox (TICKER:BW), CECO Environmental (TICKER:CECO), Donaldson Company (TICKER:DCI), and Honeywell (TICKER:HON). While these competitors often boast greater scale, broader portfolios, and superior profitability metrics (e.g., HON's TTM gross margin of 38% and net margin of 15% significantly outpace FTEK's TTM gross margin of 43.14% and net loss), Fuel Tech differentiates itself through proprietary, cost-effective solutions. Its ULTRA technology, for instance, converts urea to ammonia on-site, offering a safer and potentially lower operating cost alternative for SCR systems compared to traditional ammonia handling, providing a tangible benefit for price-sensitive customers. Similarly, its Targeted In-Furnace Injection (TIFI) technology within the FUEL CHEM segment addresses specific boiler issues like slagging and fouling, a niche where management notes there are few direct competitors. This focus on specific, performance-driven technologies allows Fuel Tech to carve out market share, estimated at 5-10% in its core areas, by offering solutions that can provide quantifiable operational or cost advantages, such as improved fuel efficiency or reduced downtime. The company's operational model, which includes leveraging computational fluid dynamics modeling, supports its ability to provide tailored solutions. While larger competitors like HON benefit from integrated automation platforms and extensive R&D budgets, Fuel Tech's strength lies in its application-specific expertise and the ability to deliver targeted outcomes. However, this smaller scale can also be a vulnerability, potentially leading to higher customer acquisition costs or slower technological development cycles compared to the industry giants. The company's strategy of pursuing opportunities driven by state-specific regulations or industrial expansion, rather than solely relying on broad federal mandates, allows it to capture business even amidst regulatory uncertainty, positioning it differently than competitors heavily reliant on large-scale environmental compliance cycles. ## Performance Reflecting Strategic Momentum Fuel Tech's first quarter 2025 financial results provide a snapshot of the company's current trajectory, highlighting both the impact of recent strategic initiatives and ongoing market dynamics. Total revenues for Q1 2025 increased 29% to $6.38 million compared to $4.96 million in the prior year period. This growth was primarily fueled by an exceptional performance in the FUEL CHEM segment, where revenues surged 92% year-over-year to $5.08 million. This significant increase was attributed by management to a combination of factors, including the return to full operational demand from the client base following outages and increased dispatch rates, as well as the sustained contribution from a new commercial account added in the second half of 2024. The FUEL CHEM segment's gross margin also saw a healthy expansion, reaching 50% in Q1 2025, up from 43% in Q1 2024, reflecting the benefits of increased volume against relatively flat administrative expenses. Conversely, the Air Pollution Control (APC) segment experienced a revenue decline in Q1 2025, falling 44% to $1.30 million from $2.32 million in Q1 2024. This decrease was primarily related to the timing of project execution on existing contracts and customer-driven delays, a recurring challenge in the capital project-oriented APC business. Despite the revenue dip, the APC segment's gross margin remained solid at 33%, though down from 38% in the prior year, influenced by changes in product and project mix. The impact of these project delays, however, is reflected positively in the company's backlog. Consolidated APC backlog at March 31, 2025, stood at $10.3 million, a substantial 66% increase from $6.2 million at December 31, 2024, and the highest level reported in three years. This backlog includes both domestic ($3.6 million) and foreign ($6.7 million) projects, with approximately $6.9 million expected to be recognized over the next 12 months, providing a degree of revenue visibility for the coming year.

On a consolidated basis, the improved gross margin performance (46% in Q1 2025 vs. 41% in Q1 2024) helped to narrow the operating loss to $952,000 in Q1 2025, a significant improvement from the $1.69 million operating loss in Q1 2024. Selling, general, and administrative (SG&A) expenses remained relatively flat year-over-year at approximately $3.34 million, but decreased as a percentage of revenue due to the top-line growth. Research and development (R&D) expenses increased to $570,000, reflecting the company's continued investment in new technologies, particularly the DGI system. The reported net loss of $739,000 in Q1 2025 contrasts with net income of $281,000 in Q1 2024, a difference primarily attributable to the absence of a one-time $1.7 million Employee Retention Credit recorded as other income in the prior year period. Excluding this extraordinary item, the underlying operational performance showed improvement.

## Outlook and Strategic Pursuits Looking ahead, Fuel Tech's management is optimistic about 2025, projecting it to be a year of growth. The company is maintaining its revenue guidance, expecting total revenues to approximate $30 million, with both the APC and FUEL CHEM segments anticipated to exceed their 2024 performance. This base case outlook is grounded in the current backlog, expected near-term APC contract conversions ($3 million to $5 million by the end of Q2 2025), and the continued strength and new account contributions in the FUEL CHEM business. Beyond this base case, several strategic initiatives represent potential upside. In the APC segment, Fuel Tech is actively pursuing opportunities related to the expansion of power generation for data centers. Leveraging its SCR and ULTRA technologies, the company is working with OEM suppliers and large tech companies, submitting budgetary bids for larger domestic contract opportunities. The significant projected investment in data center infrastructure and the associated demand for reliable, compliant power generation present a material market driver for Fuel Tech's core emissions control solutions. The company is also making tangible progress in the commercialization of its DGI water treatment technology. A key demonstration at a fish hatchery in the Western U.S. is set to commence before the end of May 2025, expected to last nine to twelve months with defined test protocols to evaluate the benefits of precise dissolved oxygen delivery in aquaculture. Discussions are also progressing for DGI demonstrations with a municipal wastewater treatment facility and potentially a large food processor, highlighting the technology's versatility across different industrial and municipal applications. Fuel Tech is hopeful that these efforts will translate into its first commercial DGI revenues in 2025 and is building out its sales channels by executing sales representative agreements. While material DGI revenue is not included in the 2025 guidance, successful demonstrations and initial commercial wins could provide future growth catalysts. In the FUEL CHEM segment, the company continues to pursue additional opportunities, including a potential new demonstration at a coal-fired unit in the Midwest expected late in Q3 2025. Internationally, discussions continue with the partner in Mexico, where the newly elected government's focus on environmental policy could potentially unlock opportunities for Fuel Tech's chemical technology program, particularly given Mexico's plans to use heavy fuel oil for power generation. Despite the positive momentum and strategic pursuits, risks remain. Customer-driven project delays, as seen in the Q1 APC results, can impact revenue timing. Regulatory uncertainty, particularly regarding the finalization and implementation of rules like the EPA's Good Neighbor Rule (currently stayed and remanded) and the delayed municipal waste combustor rule, could affect the timing and scope of future compliance-driven opportunities. Potential impacts from tariffs on materials like steel and aluminum could also affect costs, although the company aims to pass these through to customers. Competition from larger, financially stronger players with extensive R&D capabilities and broader market reach continues to be a factor. ## Conclusion Fuel Tech's first quarter 2025 results and recent developments paint a picture of a company leveraging its core technological strengths while actively pursuing new avenues for growth. The significant surge in APC backlog, coupled with the strong performance and new account contributions in the FUEL CHEM segment, provides a solid foundation for the company's 2025 revenue guidance and signals potential for improved financial performance compared to the prior year. The strategic focus on emerging markets like datacenter power generation and the dedicated efforts to commercialize the DGI water treatment technology represent compelling potential upside drivers beyond the current forecast. While challenges such as project timing and regulatory uncertainty persist, Fuel Tech's strong balance sheet and focused investment in differentiated technologies position it to capitalize on opportunities in environmental and process optimization markets. The company's ability to convert its growing pipeline of opportunities, particularly in the APC segment and the nascent DGI business, will be critical to realizing its growth potential and driving long-term shareholder value in a competitive landscape.
