Item 1A. Risk Factors Trilogy and its future business, operations and financial condition are subject to various risks and uncertainties due to the nature of its business and the present stage of exploration of its mineral properties. Certain of these risks and uncertainties are under the heading “Risk Factors” under Trilogy’s Annual Report on Form 10-K which is available on SEDAR+ at www.sedarplus.ca and EDGAR at www.sec.gov and on our website at www.trilogymetals.com. ​ ​ ​ ​ ​ ​ Trilogy Metals Inc. For the Quarter Ended February 28, 2026 24 ​ Table of contents With the exception of the addition of the below, there have been no material changes to the risk factors set forth in Trilogy’s Annual Report on Form 10-K. ​ Increases in energy prices and inflationary pressures could materially increase our capital and operating costs and adversely affect the economic viability of our projects. ​ Global energy markets have experienced significant volatility, including increases in oil and fuel prices associated with geopolitical developments involving Iran and disruptions to shipping through the Strait of Hormuz. Prolonged disruptions in global energy supply or transportation routes may lead to sustained increases in oil and other energy prices. ​ Energy costs are a significant component of the cost of developing and operating mining projects. Sustained increases in the price of oil, fuel, power and other energy inputs may increase the cost of construction, transportation, equipment operation and the production and delivery of consumables used in mining operations. Higher energy prices may also contribute to broader inflationary pressures affecting the costs of labor, materials, equipment, reagents, contractors and other services required for the development and operation of our projects. ​ Estimated capital costs, operating costs, production levels and economic returns for our projects are based on assumptions regarding, among other things, input costs, energy prices, supply chains and inflation. If energy prices remain elevated or inflation persists, actual costs may be significantly higher than our current estimates. Higher costs or increased uncertainty regarding future costs could adversely affect project development decisions, reduce projected economic returns, require additional financing or result in delays in development or construction. Any of these factors could materially and adversely affect our business, financial condition, results of operations and the economic viability of our projects. ​ Item 2. Unregistered Sales of Equity Securities and Use of Proceeds None.
