Midwest Energy Emissions Corp. and Vistra Announce Fleetwide License

and Supply Agreement

CORSICANA, TX and IRVING, TX, August 4, 2020 – Midwest Energy Emissions Corp. (OTCQB: MEEC) ("ME₂C") and Vistra Corp. (“Vistra”) (NYSE: VST) today announced the signing of a multi-year, fleetwide license and supply agreement to provide Vistra a non-exclusive license to certain ME₂C patents for use in connection with Vistra’s coal-fired power plants, and to facilitate the parties’ ongoing business relationship. Such patents licensed to Vistra relate to ME₂C’s two-part Sorbent Enhancement Additive (SEA^®) process for mercury removal from coal-fired power plants. 

As a result of the agreement being announced today, ME₂C has agreed to dismiss all claims brought against Vistra in the patent litigation initiated by ME₂C, and Vistra has agreed to withdraw from petitions for Inter Partes Review which had been filed with the United States Patent and Trademark Office pertaining to such patents.  These proceedings will continue with respect to the other parties involved.

Richard MacPherson, President and CEO of ME₂C, stated “We are pleased to have reached this business arrangement with Vistra, a longstanding customer who we believe has achieved significant value from both our patented products and services for many years. With the agreement being announced today, we are confident in retaining Vistra’s current business and look forward to working with them to enhance their performance at other plants within their fleet. We believe this agreement validates the efficacy of our patented approach to mercury capture.”

Vistra Chief Fossil Officer, Barry Boswell, said, “We are happy to have resolved this matter with ME₂C.  Our companies have been doing business together for over a decade, and we look forward to the prospect of continuing that relationship.”
