NORTHSTAR REPORTS 2025 YEAR END FINANCIAL AND OPERATING RESULTS

CALGARY, AB, April 29, 2026 /PRNewswire/ - Northstar Clean Technologies Inc. (TSXV: ROOF) (OTCQB: ROOOF) ("Northstar" or the "Company") is pleased to announce its financial and operating results for the three- and twelve-month period ended December 31, 2025. Selected financial and operational information is set out below and should be read in conjunction with the Company's December 31, 2025 financial statements and the related management's discussion and analysis, which are available for review at www.sedarplus.ca or the Company's website at www.northstarcleantech.com. 

"We view 2025 as a significant transitional year for Northstar, as we constructed and commissioned our first commercial facility, Empower Calgary," said Aidan Mills, President & CEO of Northstar. "This included the first production of liquid asphalt from post-consumer and manufactured waste shingles, achieving our first throughput milestone of 80 tpd, and the first sale of liquid asphalt to McAsphalt, an important step toward regular revenue generation. As expected of a first-of-its-kind commercial facility, this transition wasn't without challenges, but the strength of the team and underlying technology allowed us to meet these head on, and these learnings are directly informing our path toward stable, long-term production."
