Northstar Clean's patents buy time, not money

Northstar Clean Technologies is well patented for a company of its size. The Calgary reprocessor of old asphalt shingles (TSXV: ROOF; OTCQB: ROOOF) holds American grants from 2022 and 2024 and Canadian grants from 2024 and 2025, and last September it was awarded a further American patent for the step that recovers limestone from shingles, protection running to 2045. Management calls the company a "clear first mover" in an industry whose raw material mostly ends up in landfill. The patents are the least uncertain thing about it. Everything else is the test of whether a plant-based business can make money.

The raw material glut is real. Americans strip roughly 13m tonnes of asphalt shingles off roofs every year, and almost all of it goes to landfill; Canada adds around 1.5m more, by the company's count. Northstar's four-stage "BEST" process grinds discarded shingles apart and sells the parts — liquid asphalt, aggregate, fibre and, now, limestone. The circular-economy pitch is that one roof becomes the binder in the next road or the filler in the next roof, at a fraction of the virgin-material carbon cost. The reality that tests the pitch is an industrial ramp.

Northstar's first commercial plant, near Calgary, has capacity for 80,000 tonnes a year on two shifts. It has spent 2026 learning the difference between capacity and output. After reaching 80 tonnes a day in late 2025, then tripping over three bottlenecks, the plant briefly ran above 120 tonnes a day in June. Management expects fully ramped production of about 150 tonnes a day, the company's "Milestone 4", in the third quarter, after a debottlenecking upgrade planned for this autumn.

The accounts expose the distance travelled. In the first quarter of 2026 Northstar booked revenue of C$208,458 — against a forecast near C$1.8m, a miss of almost 90%. For all of 2025 it lost C$14.75m on revenue of barely C$600,000, and it ended the year with C$457,000 of cash, down from C$10.2m a year earlier. The market's patience is priced in: the shares change hands at about C$0.19. The equity is worth roughly C$30m, about half its 52-week high of C$0.38.

What the patents cannot settle is who captures the value the process creates. That is decided by the company's relationships. Every litre of liquid asphalt produced at the Calgary plant is committed, under an offtake agreement, to McAsphalt, a subsidiary of the French roads group Colas. The first sale was made in December 2025. Northstar's strategic investor, TAMKO, an American shingle maker, put US$10m into the company in 2023, can appoint a director, and holds the right to buy most of the asphalt from Northstar's first four American plants. The first is planned for Baltimore, fifty miles from TAMKO's own shingle factory in Maryland. The manufacturers therefore sit on both sides of the trade — a rival, IKO, feeds Northstar scrap under a five-year deal — which means the market is genuine but the pricing may not be entirely Northstar's to set.

Scale must then be funded. The US$10m of convertible debentures that closed in March and April carry an 8% coupon and a conversion price of US$0.20. The next two plants, in Hamilton and Baltimore, already carry claims of their own: a royalty investor takes a minimum 13.2% of their revenue once its debenture converts, on top of a C$8.75m senior loan from Canada's Business Development Bank and more than C$7m of Alberta grants for the first facility. Northstar's stated ambition is 23 plants by 2030, each to be built with prior claims attached and with the cash-raising treadmill running.

None of this dooms the model. TAMKO and McAsphalt are not charities; a manufacturer does not take roughly a fifth of an investee's equity and the output of four future plants unless it expects the process to work, and the patents, in force to 2042 and beyond, buy time. But the order of achievements is telling. The technology has been patented, the process protected and the output sold — and the company still turns in quarterly revenue of six figures against an eight-figure annual loss. The question that decides the shares is not whether the chemistry works at 80 tonnes a day. It is whether one plant, running at 150 tonnes a day and financed by a tower of convertible claims, can earn a margin that pays for its own growth. No patent can answer that.
