FUEL TECH REPORTS 2020 THIRD QUARTER FINANCIAL RESULTS

WARRENVILLE, Ill. - November 10, 2020 - Fuel Tech, Inc. (NASDAQ: FTEK), a technology company providing advanced engineering solutions for the optimization of combustion systems, emissions control and water treatment in utility and industrial applications, today reported financial results for the third quarter ended September 30, 2020 ("Q3 2020").

"Although we have experienced some deferred decision-making on the part of some customers due in part to uncertainty created by the effect of COVID-19 pandemic, I am very proud of how our team has continued to navigate these challenging times. As a result of their efforts, we are seeing encouraging signs across our enterprise," said Vincent J. Arnone, President and CEO. "Within our Air Pollution Control (APC) business segment, we remain intensely focused on providing custom-engineered solutions that fulfill the unique needs of each of our customers, and expect the final decisions to be made on multiple projects by the end of the year which, if Fuel Tech's bids are selected, would increase backlog for 2021 and beyond by $10 to $15 million."

"Our FUEL CHEM® segment results reflected contributions from the installation of our TIFI® Targeted In-Furnace Injection technology on three new domestic coal-fired units for a repeat customer in the Northeast, as well as a return to normalized run rates across our fleet following a period of slower unit activity in Q2 2020 due to the COVID-19 pandemic. The commercial programs represented by these three new units will generate revenue when the units are dispatched to generate power in their respective geographic areas. If these units are operational and utilizing the technology on a continual basis throughout the year, we would expect to see revenues of $500,000-$750,000 per unit. Longer term, we continue to build on our progress with our partner in Mexico to employ our FUEL CHEM solutions to help mitigate harmful emissions from burning high sulfur fuel oil. Our partner continues to engage with local officials in Mexico to advance this solution and we are continuing to support its efforts in this regard."

Mr. Arnone concluded, "We have collected and repatriated in excess of $1 million in cash as of September 30, 2020 following the closure of our underperforming China operation ("Beijing Fuel Tech"), and expect to continue these collections throughout 2020. We ended the quarter with $11.8 million in cash and cash equivalents."

DGI™ Dissolved Gas Infusion

The Company is pursuing three new opportunities to demonstrate its dissolved gas infusion technology, one to a new customer in the pulp and paper business located in the Pacific Northwest and the remaining two for municipal wastewater treatment applications in conjunction with our partner Kadance Corporation. As previously reported, an on-site demonstration of Fuel Tech's DGI technology at a pulp and paper facility in the Midwest planned for early in Q2 2020 has been delayed due to the impact of COVID-19. The Company is encouraged to see the increase in interest in this technology application and looks forward to providing additional information regarding the progress of these demonstrations in the future. In addition, in Q3 2020 the Company signed a new license agreement related to the DGI technology with Kadance which purchased the assets of our prior licensor of the technology. Kadance is focused primarily on serving the municipal wastewater treatment market and also offers the ability to deliver biological treatment solutions. Under the terms of the new agreement, among other things, Fuel Tech has been provided expanded access to markets outside of municipal wastewater treatment and has the right to independently manufacture DGI systems.

Q3 2020 Consolidated Results Overview

Consolidated revenues increased 26.4% to $8.2 million from $6.5 million in Q3 2019, reflecting higher revenue in both the APC and FUEL CHEM segments.

As previously announced, Fuel Tech reached a settlement with its insurance carrier ("the settlement") that resulted in the Company receiving $2.6 million in proceeds related to an outstanding claim that was previously reported in 2019. The proceeds of the settlement were received in Q4 2020, however, in Q3 2020 the Company recorded a receivable for the proceeds that reduced cost of sales at the APC business by a like amount.

Gross margin for Q3 2020 was 72.4% of revenues compared to 44.8% of revenues in Q3 2019, primarily reflecting the impact of the settlement on APC costs of sales. Excluding the settlement, consolidated gross margin for Q3 2020 was 40.7%.

SG&A expenses declined by 16.7% to $3.2 million from $3.8 million in Q3 2019, reflecting lower administrative and professional services costs.

Net income from continuing operations was $2.4 million, or $0.10 per share, compared to net loss from continuing operations of $(1.3) million, or $(0.05) per share, primarily due to the impact of the aforementioned settlement in Q3 2020.

Capital projects backlog at September 30, 2020 was $6.4 million, $6.0 million of which was domestic. Backlog at December 31, 2019 was $9.7 million, of which $8.6 million was domestic.

APC segment revenues improved to $2.9 million from $1.8 million in Q3 2019, primarily the result of project timing, and the decrease in new APC orders announced during 2019 and continuing through the first nine months of 2020. APC gross margin was $3.2 million, or 110% of revenue, reflecting the above referenced settlement, compared to gross margin of $0.6 million, or 34.1%, in Q3 2019. Excluding the settlement, APC gross margin for Q3 2020 was 20.8%.

FUEL CHEM segment revenues rose to $5.3 million from to $4.6 million in Q3 2019, primarily reflecting installations of three new units during Q3 2020. Segment gross margin was 51.7% in Q3 2020 and 49.0% in Q3 2019.

Adjusted EBITDA was $2.7 million in Q3 2020 compared to an Adjusted EBITDA loss of $(0.8) million in Q3 2019.
