## Overview

Fuel Tech, Inc. develops proprietary technologies that help power and industrial plants reduce air emissions, optimize combustion, and treat water. Its core offerings center on NOx reduction, air pollution control, and the FUEL CHEM program, which is used to control slagging, fouling, corrosion, and sulfur-related issues in boilers and furnaces.

## Products & services

• NOxOUT® and Advanced SNCR systems
• ASCR® and SCR reagent supply systems (ULTRA®, U2A, UDI™)
• Electrostatic Precipitator (ESP) and Flue Gas Conditioning (FGC)
• FUEL CHEM / TIFI® Targeted In-Furnace Injection™
• Water treatment and advanced engineering services

- **Air Pollution Control (APC)** (33%) — NOx reduction, particulate control, flue gas conditioning and related emissions-control systems for boilers and industrial units.
- **FUEL CHEM** (67%) — Chemical and modeling-based boiler treatment programs that reduce slagging, fouling, corrosion and SO3-related operating issues.

- NOxOUT® and Advanced SNCR systems for nitrogen oxide reduction
- ASCR® systems and SCR reagent supply technologies
- ESP particulate control and flue gas conditioning solutions
- FUEL CHEM / TIFI® for slagging, fouling and SO3 control
- Water treatment technologies and engineering services

## Customers

Fuel Tech sells mainly to utility and industrial power-generation customers that need to comply with emissions rules or improve boiler reliability and efficiency. Its FUEL CHEM business also serves coal-, oil-, biomass- and waste-to-energy-fired facilities, including plants in pulp and paper, university and district heating markets. Customer concentration is high, with a small number of accounts contributing a large share of revenue.

- **Utility power generation** (primary) — Buys APC and FUEL CHEM solutions to meet emissions rules and improve plant uptime and efficiency.
- **Industrial combustion facilities** (primary) — Buys boiler optimization and pollution-control technologies to reduce operating disruptions and environmental impact.
- **Coal-fired plants** (primary) — Uses FUEL CHEM and APC products to manage slagging, fouling, SO3 and NOx issues in coal units.
- **Oil-, biomass- and waste-to-energy plants** (secondary) — Uses targeted chemical and emissions-control programs to improve combustion performance and emissions compliance.
- **Pulp and paper, university and district heating markets** (secondary) — Buys specialized combustion-treatment programs for smaller-scale boilers and furnaces.

- Utility power plants buying emissions-control and boiler optimization systems
- Industrial boilers and furnaces needing reliability and efficiency gains
- Coal, oil, biomass and waste-to-energy operators using FUEL CHEM programs
- Customers facing NOx, SO3, slagging and fouling compliance/operating issues
- A small number of large accounts drive a disproportionate share of revenue

## Geography

Fuel Tech is headquartered in Warrenville, Illinois and operates as a U.S.-domiciled company with a small European employee base. Its technologies are installed worldwide, with APC backlog split between U.S. domestic and international projects, and FUEL CHEM programs deployed across North America, Europe and the Pacific Rim. The business remains exposed to coal-heavy power markets such as the U.S., China, India and Mexico, where emissions and fuel-quality issues support demand.

- **United States** (0%) — No country-level revenue split was disclosed in the provided excerpts.

- Headquartered in Warrenville, Illinois, United States
- Most employees are in North America, with a small presence in Europe
- APC backlog includes both U.S. domestic and international projects
- FUEL CHEM installations span North America, Europe and the Pacific Rim
- Demand is tied to coal and fossil-fuel power markets in the U.S., China and India

## Strategy

Management is focused on preserving liquidity, reducing expenses and restructuring operations while supporting the base APC and FUEL CHEM businesses. Growth depends on converting backlog, winning new FUEL CHEM customers, and extending the life of fossil-fuel-fired assets that still need emissions and boiler-performance solutions.

- **Liquidity preservation and cost reduction** (short-term) — Recent losses and revenue volatility require a leaner operating structure to fund the business.
- **Grow FUEL CHEM customer base** (medium-term) — The segment has shown stronger demand and can offset weakness in APC project timing.
- **Defend and monetize proprietary technology** (long-term) — Patents and specialized know-how are central to differentiation against chemical and engineering competitors.

- Protect liquidity and working capital through expense control
- Support the core APC and FUEL CHEM businesses with limited capex
- Win new FUEL CHEM customers and expand non-coal applications
- Convert backlog despite project timing and award delays
- Leverage proprietary patents and installed base to defend pricing

## Risks

Fuel Tech is exposed to customer concentration, project timing risk and the structural decline of coal-fired generation over time. Its results also depend on regulatory demand for emissions control, the pace of energy transition, and the ability to protect proprietary technologies against competitors and cyber threats.

- **Customer concentration** [high] — Five customers represented about 58% of 2025 revenue, so a single loss can materially affect results.
- **Project timing and backlog conversion** [medium] — APC revenue is driven by contract execution timing and award delays, creating quarter-to-quarter volatility.
- **Energy transition / coal decline** [high] — A large part of demand depends on continued fossil-fuel use, especially coal-fired generation.
- **Technology and patent protection** [medium] — The business relies on proprietary processes and patents to defend differentiation and pricing.
- **Cybersecurity** [medium] — A cyber incident could disrupt systems, damage reputation and trigger remediation or legal costs.

- High customer concentration can cause sharp revenue swings if one account is lost
- APC revenue depends on project timing and contract awards
- Coal decline and renewable growth can reduce long-term demand
- Competition from specialty chemical suppliers pressures FUEL CHEM pricing
- Cybersecurity and supplier dependence can disrupt operations and customer trust

## Accounting

Revenue can be volatile because APC projects depend on contract execution timing, while FUEL CHEM revenue is tied to customer outages, dispatch levels and commercial program adoption. Investors should also watch goodwill impairment judgments, because the FUEL CHEM reporting unit is tested using discounted cash flow assumptions that are sensitive to revenue growth, margins and market conditions.

- **Revenue recognition timing** — Quarterly and annual revenue volatility
- **Goodwill impairment** — Potential non-cash impairment charges
- **Long-lived asset impairment** — Non-cash charges and lower asset values
- **Estimation of fair value** — Reported asset values and impairment conclusions

- APC project timing can shift revenue between quarters and years
- FUEL CHEM revenue depends on outage completions and dispatch activity
- Customer concentration increases the impact of any delayed or canceled order
- Goodwill impairment hinges on DCF assumptions for the FUEL CHEM unit
- Patents and long-lived assets require ongoing impairment monitoring
