HPQ ANNOUNCES SECOND AND FINAL CLOSING OF PRIVATE PLACEMENT

HPQ Silicon Inc. closed yesterday the non-brokered private placement financing first announced on May 29, 2025.

In addition to the 3,158,000 units announced on June 19, 2025, the company announces the closing of an additional 1,886,331 units at a price of 18 cents per unit for gross proceeds of $339,539.58, bringing the total amount raised at $907,979.58 and the total number of units issued at 5,044,331.

Each unit is composed of one common share and one common share purchase warrant of the company. Each warrant will entitle the holder thereof to purchase one common share of the capital stock of the company at an exercise price of 25 cents for a period of 48 months from the date of closing of the placement. Each share issued pursuant to the placement will have a mandatory four-month-and-one-day holding period from the date of closing of the placement. The placement is subject to the approval of the TSX Venture Exchange and other regulatory authorities.

"Closing this financing of more than $900,000 at a nearly 9-per-cent premium, despite less-than-ideal market conditions, is a strong validation of the market's confidence in HPQ's value proposition," said Bernard Tourillon, president and chief executive officer of HPQ Silicon. "While modest in size, this financing lays a solid foundation for HPQ to capitalize on the larger opportunities we are actively pursuing."

In connection with the placement, CI Investment Services Inc. of Toronto, Ont., received a cash commission equal to $5,219.97, and the company issued to it 29,000 broker warrants. Each broker warrant will entitle the broker to acquire one common share of the company at a price of 25 cents per share for a period of 48 months following the closing date of the placement and is subject to the mandatory four-month-and-one-day holding period from the date of closing of the placement as the warrants of the placement.
