The Company has scheduled a virtual investor webcast to discuss these financial results and to provide a business update to the investment community on Thursday, April 28, 2022 at 2:00 pm PST / 5:00 pm EST. Details are provided below.

Mr. Aidan Mills, President & CEO of Northstar, commented, "In 2021, the Northstar team did an excellent job of laying the groundwork for Northstar's future. 2021 was the most progressive and successful year for our Company to date. Our $12.24 million financing completed in July 2021 funded the development of our Empower Pilot Facility in Delta, British Columbia and supported the development of our planned Calgary Empower Facility in Calgary, Alberta. We are now in steady state production at our Empower Pilot Facility and progressing towards commercial production. We also recently completed our independent front-end engineering design ("FEED") for our planned Calgary Empower Facility. The completion of the FEED design was a significant milestone for us and validated our cost estimates allowing us to move forward with even more confidence as we begin work on our Calgary Empower Facility."

Mr. Mills continues, "Putting all of this together, we are confident that Northstar will play a pivotal role in the circular economy and that we are well positioned to capitalize on the triple bottom line:  people, planet and profit. These past six months have been defined by an independent third-party validation of our business, confirmation that we are producing specification product with our technology, and establishing the foundation to build a low carbon, circular economy business across North America. The independent life cycle assessment validated strong carbon dioxide emission savings of 60%, cementing our view that the reprocessing of asphalt shingles is significantly greener than the landfill alternative. 2022 is shaping up to be an exciting year for our Company."

Q4 2021 Highlights

• October 2021 - Northstar announced the successful completion of commissioning runs at its Empower Pilot Facility and completed an assessment of Request for Proposal ("RFP") submissions.
• November 2021 - Selected BBA Engineering Ltd. ("BBA") as consulting engineering firm to conduct the FEED study producing the detailed engineering design of a modular facility to be deployed across expansion facilities.
• November 2021 – Completed an independent life cycle assessment for the Empower Pilot Facility, confirming that the facility has the capacity to reduce carbon dioxide equivalent ("CO₂e") emissions of liquid asphalt production by 60%.
• December 2021 - Appointed Ms. Rosemary Pritchard as Chief Financial Officer and lead for the Company's human resources and information technology.

Notes:

(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.
