PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), a TSX30® and a Deloitte Technology Fast 50™ high-tech company (hereinafter referred to as the “Company” or “PyroGenesis”), that designs, develops, manufactures and commercializes advanced plasma processes and sustainable solutions which are geared to reduce greenhouse gases (GHG), is pleased to announce today that, further to its press releases dated September 21, 2022 and November 2, 2022, all of the findings and recommendations made by a leading global aerospace company (the “Client”), as part of their on-site audit of PyroGenesis' NexGen™ metal powder production facility have been successfully completed and accepted.

Now that the Client has approved and accepted PyroGenesis’ NexGen™ manufacturing process, the next and final step is to provide sample titanium metal powder from the newly approved NexGen™ manufacturing process. The plasma atomized metal powder produced from PyroGenesis' proprietary state-of-the-art process (NexGen™) will be used for verification and confirmation of their chemical and mechanical properties.

“The Client is a very discerning aerospace company with some of the most stringent and demanding standards. As such, we are very proud to have gained their confidence and to be moving forward to the final phase,” said Mr. Massimo Dattilo, VP PyroGenesis Additive. “We have methodically completed all steps in the client’s on-site quality audit, leaving only the verification of the chemical and mechanical properties of PyroGenesis’ plasma atomized metal powders as the last step. We believe the difficult part is now behind us, and we are looking forward to the prospect of becoming a fully-fledged approved supplier of titanium powder to one of the largest potential clients in North America. Once an approved supplier, PyroGenesis Additive could also supply their service centers.”

Having already passed this rigorous qualification process, management is of the opinion that future qualification audits from potential clients will now be completed in a significantly shorter time frame. PyroGenesis Additive is currently addressing an influx of opportunities from the past year and continues to expand its team in anticipation of meeting this demand.
