PyroGenesis Comments on Recent Online Post

MONTREAL, Oct. 12, 2025 (GLOBE NEWSWIRE) -- PyroGenesis Inc. (“PyroGenesis” or “the Company”) (TSX: PYR) (OTCQX: PYRGF) (FRA: 8PY1), the leader in innovating for ultra-high temperature processes and engineering, and a technology provider to heavy industry & defense, provides the following comment in regard to a recent online post from a current member of the Company’s board of directors.

On Saturday October 11, 2025, it came to the Company’s attention that an online post from a current member of the PyroGenesis board of directors had been made on the night of Friday October 10, outside of market hours. This post contained information regarding the Company’s recently announced non-brokered private placement (the “private placement”). A portion of this information should not have been posted and is incorrect. Upon recognizing the error, the post was quickly deleted. PyroGenesis asks that any versions of this since-deleted post be disregarded and not disseminated further.

More specifically, the post contained details about the private placement that had been previously released, however it also contained a sentence that “… (the Company’s ongoing private placement) has been oversubscribed bringing in between $7.5-$8.0 million to the company…”.

While the Company had previously announced, on October 1, 2025, its intention to conduct this non-brokered private placement, with a potential funding of approximately $5 million, the private placement is currently ongoing, and neither a statement of oversubscription, nor a suggestion that the private placement is complete, can be formally, nor accurately, stated at this time.

As a matter of clarification, the Company can state that, at the time of this press release, the private placement is not officially oversubscribed. We can further confirm that the first tranche of the first unit group of the private placement, is expected to be completed during the upcoming week.

PyroGenesis is committed to timely disclosure and takes corporate governance seriously. The board of directors has reviewed this situation in full, and corrective action has been taken.
