PyroGenesis’ CEO Comments on Recent SEDI Filings

MONTREAL, Dec. 10, 2018 (GLOBE NEWSWIRE) — PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX-V: PYR) (OTCQB: PYRNF), a TSX Venture 50® high-tech company, (the “Company”, the “Corporation” or “PyroGenesis”) a Company that designs, develops, manufactures and commercializes plasma atomized metal powder, plasma waste-to-energy systems and plasma torch products today responds to investor inquiries regarding recent insider reports filed on the System for Electronic Disclosure by Insiders (“SEDI”).

SEDI is Canada’s on-line, browser-based service for the filing and viewing of insider reports as required by various provincial securities rules and regulations.

Last Friday, insider reports were filed on SEDI reflecting the sale of 80,500 common shares by the Chairman of PyroGenesis’ Board. This amounts to less than 0.7% of all outstanding shares and was done outside of any black-out period for the sale of shares.

“These shares were sold by our Chairman for purely personal requirements and had nothing to do with his confidence in, or the state of, the Company. Nor does it reflect any change, or impending change, in his status with the Company. We are happy and proud to have Mr. Curleigh as the Chairman of our Board,” said P. Peter Pascali, CEO of PyroGenesis Canada Inc. “We normally do not comment on such filings but given the unusual number of investor inquiries with respect to these filings, and considering our recent press releases, we thought it prudent to provide some additional context. On that note, and with respect to the insight provided in our recent press releases, I can confirm that what was disclosed in those press releases is truer now than when it was written.”

“Regretfully, the option to have other Board members purchase these shares was not a possibility at this time, otherwise we would have,” added Mr. Pascali.

Of note, three other board members bought shares recently. An entity related to Mr. Pascali bought 3,448,276 common shares for $2MM  which was at a significant premium (>30%) to the market price at the time of purchase. Two other Board members exercised options with the intent to hold. No shares were sold to cover the exercise of these options.
