WARRENVILLE, Ill. – May 5, 2020 – Fuel Tech, Inc. (NASDAQ: FTEK) (or “the Company”), a technology company providing advanced engineering solutions for the optimization of combustion systems, emissions control and water treatment in utility and industrial applications, today announced that it would adjourn its annual meeting of stockholders (“annual meeting”) to June 16, 2020 at 10:00 a.m. (Warrenville, Illinois time) at the Company’s corporate headquarters in Warrenville, Illinois. The annual meeting was originally scheduled for May 20, 2020, but in light of current public health concerns related to COVID-19 and related public health measures, the Company considers it prudent to delay the annual meeting. Stockholders should not travel to the Company’s offices on the original date.

At the annual meeting on June 16, the Company expects that in-person attendance will be possible consistent with social distancing requirements. In order to facilitate stockholder participation, the Company will host a conference call for those wishing to listen in. Interested parties may call into the annual meeting by using the dial-in information shown below. However, the Company expects that the meeting will be briefer than normal and be limited to the items to be voted on at the annual meeting. The Company does not intend to have management make a presentation. Stockholders of record on March 23, 2020, the original record date, may continue to vote in person or by proxy until June 16, 2020. Consistent with guidance by the State of Delaware and the U.S. Securities and Exchange Commission, the Company will not be mailing additional proxy materials with respect to the new annual meeting.

Additional information regarding the annual meeting including the proposals to be voted on can be found in the Company’s proxy statement on Schedule 14A, which was filed with the Securities and Exchange Commission on March 25, 2020. A copy may be obtained free of charge at www.sec.gov

The Company continues to monitor current public health measures and if it considers it prudent, the Company may further adjourn the annual meeting to a different time or place. If so, the Company will issue a further press release announcing any such additional changes.
