PyroGenesis Announces Successful Completion of Additive Manufacturing NexGen™ Powder Test Runs; Commercial Powder Production Begins

MONTREAL, May 12, 2021 (GLOBE NEWSWIRE) -- PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), a high-tech company, (hereinafter referred to as the “Company” or “PyroGenesis”), that designs, develops, manufactures and commercializes plasma atomized metal powder, environmentally friendly plasma waste-to-energy systems and clean plasma torch products, is pleased to announce that, further to its press release dated April 19^th, 2021, powder test runs for batch to batch consistency using its cutting edge Additive Manufacturing (“AM”) NexGen™ powder production line has been completed successfully, and ahead of schedule. The Company is now producing AM metal powders for clients.

“We are happy to announce this significant milestone, almost two months ahead of the schedule announced on April 19^th. The strategic decision previously made to delay powder production to incorporate several revolutionary improvements into the existing production line (increased production rate, lower CAPEX, lower OPEX, narrower particle size distribution) means that PyroGenesis is entering the AM powder market with a production line which management believes is the low-cost producer in its class. Management also believes that the NexGen™ powder production line will also enable PyroGenesis to uniquely process materials which, until today, did not seem economically feasible,” said Mr. P. Peter Pascali, CEO and Chair of PyroGenesis. “It is very exciting to know that we are now going to be delivering powders to very discerning and distinguished clients. However, I want to caution readers not to be expecting hundreds of tons of powder orders next week. As everything we do “…slow is smooth and smooth is fast…”, it is a strategy that we have perfected. It has worked well for us up to now, and we see no reason to change it.”

“We are where we want to be,” said Mr. Massimo Dattilo, Vice President of PyroGenesis Additive. “The next step is to complete the qualification processes and secure large long-term contracts, thereby providing PyroGenesis with recurring revenues for years to come. This will obviously take time, but we are there now. With the advantages of the NexGen™ powder production line, we believe it is only a matter of time given the major top tier aerospace companies and OEMs are already awaiting powders from this new state-of-the-art production line.”
