Vancouver, BC – Northstar Clean Technologies Inc. (TSXV: ROOF ,OTCQB: ROOOF) (“Northstar” or the “Company”) is pleased to announce that today it has filed its first quarter 2022 financial statements and management’s discussion and analysis (“MD&A”) on SEDAR for the 3 months ended March 31, 2022. These documents are also available on the Company’s website at www.northstarcleantech.com. The Company has scheduled a virtual investor webcast to discuss these financial results and to provide a business update to the investment community on Tuesday, May 31, 2022 at 5:30 am PST / 8:30 am EST. Details are provided below.  Mr. Aidan Mills, President & CEO of Northstar, commented, “The first quarter was a pivotal one for Northstar as it demonstrated that the company has the potential to deliver the steps needed for an ESG business to succeed: 1) a technology that works; 2) the ability to scale up that technology; and 3) a clear commercialization strategy.”  “The achievement of steady state production and the delivery of specification product at the Empower Pilot Facility in Delta B.C. clearly demonstrates step 1. These products have undergone rigorous testing by several potential customers across the Company’s target market sectors, and we continue to believe that liquid asphalt produced by Northstar is suitable in paving, shingle manufacturing and roofing system (“flat roof”) manufacturing. In parallel with the customer testing, we have added in-house and independent third-party testing to our capabilities,” Mr. Mills stated. “Stringent quality control procedures are now in place for softening point, penetration, and flash point specifications which are a key customer requirement and now an integral part of our steady state production processes. Both steady state production and customer feedback has enabled us to identify areas of plant improvement – both for the Empower Pilot Facility in Delta B.C. and to be incorporated into the next detailed design phase for the Calgary scale-up facility (“Empower Calgary Facility”).”  “The selection of Calgary as our first scale-up location, combined with our announcement of the successful completion of the front-end engineering design (“FEED”) for our Empower Calgary Facility means we are on a clear pathway to step 2. The FEED design outlined a total capital cost estimate of $11.75 million for the Calgary Empower Facility, which includes $9.75 million in direct and indirect costs, plus an additional $2.0 million contingency. The recently announced life-cycle analysis, based on the FEED design, seeks to demonstrate that the Empower Calgary Facility that has a 60% lower carbon emissions footprint versus the base case of sending shingles to landfill and replacing the asphalt content with virgin production,” continued Mr. Mills.  “Lastly, our announced project economics includes $7.6 million in estimated annual revenue per facility(1), $4.9 million in estimated annual gross profit per facility(1), and $4.0 million in potential annual EBITDA per facility(1)(2). Additionally, we believe there is clear achievable targets identified for asphalt pricing, which recently eclipsed $1,000 per tonne, sustainability or ‘green’ premium, operational performance, carbon credit revenue, tipping fee revenue, and operating assumptions. This detailed analysis of the economics for our facilities, combined with the strong potential customer feedback from their detailed asphalt testing programs hopes to show that step 3 is achievable.”   “In summary, we have a highly cost-effective, low carbon production asset running a technology capable of producing high quality products in demand by material customers and delivering strong economic performance. 2022 is shaping up to be an exciting year for our Company,” concluded Mr. Mills.  Based on these results, the Company believes that its technology works, which is shown through the steady state production at the Empower Pilot Facility, it is commercially viable and environmentally impactful.   Q1 2022 Highlights

Significant Events Subsequent to the Quarter Ended March 31, 2022

• April 2022 – Announced project economics for the Calgary Empower Facility based on the FEED design and detailed internal management-prepared financial analysis of the planned facility. Highlights include $7.6 million in estimated annual revenue per facility(1), $4.9 million in estimated annual gross profit per facility(1), and $4.0 million in potential annual EBITDA per facility(1)(2). Identified achievable targets for asphalt pricing, which recently eclipsed $1,000 per tonne, sustainability or ‘green’ premium, operational performance, carbon credit revenue, tipping fee revenue, and operating assumptions. 
• May 2022 – Announced life cycle analysis for the Calgary Empower Facility demonstrating a 60% reduction in carbon dioxide equivalent emissions versus the base case of landfill and replacement with virgin production, based on the FEED design and detailed internal management-prepared financial analysis of the planned facility.

1. Based on anticipated first full operational year. 
2. Earnings before interest, taxes, depreciation and amortization (“EBITDA”) is a Non-GAAP financial measure and refers to earnings determined in accordance with IFRS, before depreciation and amortization, interest expense (finance costs) and income tax expense. EBITDA should not be construed as alternatives to net income/loss determined in accordance with International Financial Reporting Standards (“IFRS”). EBITDA does not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. The Company believes that EBITDA is a meaningful financial metric as it measures cash generated from operations which the Company can use to fund working capital requirements, service future interest and principal debt repayments and fund future growth initiatives.
