VANCOUVER, BC, Aug. 24, 2023 /CNW/ - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce that it has filed its second quarter 2023 unaudited financial statements and management's discussion and analysis on SEDAR for the six months ended June 30, 2023. These documents are also available on the Company's website at www.northstarcleantech.com.

Mr. Aidan Mills, President & CEO and Director of Northstar, stated, "Our recent progress was punctuated by the execution of a term sheet for $8.75 million in debt with BDC in mid-June and shortly thereafter, we entered into a definitive credit agreement on similar terms in early July 2023. Securing attractive project debt was a key part of our strategy to fully fund the development and construction of the planned Empower Calgary Facility."

"In July, we secured a US$10.0 million strategic investment from TAMKO, one of America's largest independent shingle manufacturers. By closing Phase 1 of this strategic investment of approximately C$8.5 million in preferred shares, in conjunction with ERA and BDC, we have now fully funded the construction and development of the Empower Calgary Facility. To bring on a strategic equity investor, in a particularly challenging capital markets environment, marks a major milestone for the Company."

"In summary, we have delivered four major milestones for the Empower Calgary Facility in 2023: (i) a major multi-national off-take partner to purchase 100% of our highest value product for a minimum of 5 years at market based pricing, (ii) up to $7.1 million in non-repayable government grants from ERA, (iii) $8.75 million in long-term project debt from BDC on attractive terms, and (iv) US$10 million in a strategic equity investment from a major shingle manufacturer. Despite challenging market conditions, we have delivered for shareholders and are proud of our accomplishments."
