We will achieve this through building a diversified portfolio of scale over high quality assets that drives low volatility earnings growth and shareholder returns. The mining sector has an essential role to play in the energy transition, with commodities such as copper, nickel and cobalt - key materials for manufacturing batteries and electric vehicles. Copper also plays a critical role in our electricity grids. All these commodities are mined and there are not enough mines in operation today to supply the volume required to achieve the energy transition.Our strategy is to acquire royalties and streams over low-cost operations and projects with strong management teams, in well-established mining jurisdictions. Our portfolio has been reweighted to provide material exposure to this commodity basket and we have successfully transitioned from a coal orientated royalty business in 2014 to one that by end of 2026 will be materially coal free and comprised of over 90% exposure to commodities that support a sustainable future. The fundamental demand outlook for these commodities over the next decade is very strong, which should significantly increase the value of our royalty portfolio.Ecora's shares are listed on the London and Toronto Stock Exchanges (ECOR) and trade on the OTCQX Best Market (OTCQX: ECRAF).Cautionary statement on forward-looking statements and related informationCertain statements in this announcement, other than statements of historical fact, are forward-looking statements based on certain assumptions and reflect the Group's expectations and views of future events.
