Dear Sorrenson,

Please find in bold underlined the replies to your queries after your questions in italics in the text below.

"Your Q3 financials state HPQ purchased $ 3.6 million worth of IP from Pyrogenesis in Q3. No announcement of any form was made by either party.   Can you advise the investors what specific  IP was purchased? "I do not believe it is QRR or NSIR as they have been paid for previously."

The answer was on page 7 of the Q3 MDA:

"As part of its IP portfolio strategy to protect the PUREVAP™ QRR technologies, HPQ acquired from PyroGenesis in September 2022, a new intellectual property regarding a “Low Carbon Emission Process for the production of Silicon”.

"When will the investors receive an official press release with disclosure of the specific details of this substantial  purchase including the terms."

We have divulged what was minimally required to do at this time, as per potential future press release, I cannot comment.

Regards

Bernard Tourillon CEO
