Ero Copper (ERO) is rated Buy with a $50 target, reflecting a 42% upside as copper production is set to rise by a third by 2028. ERO trades at a 5.74x forward EV/EBITDA, below its historical and sector averages, despite capex nearing completion and leverage dropping to 0.8x. Caraíba's production growth hinges on timely shaft completion; delays would push the investment case out a year and undermine the valuation.
