Rio Tinto reported its smallest full-year underlying earnings in five years on Wednesday that also came in below expectations, as lower prices for iron ore outweighed growth in its copper and aluminium businesses.

Underlying earnings totaled $10.87 billion, down 7.6% year over year. Analysts expected underlying earnings of $11 billion

Rio followed rival BHP in releasing results, and dividends, hit by lower iron ore prices. RIo chief executive Jakob Stausholm presented the results from Washington where he is discussing aluminium tarrifs. Main takeaway: Weak iron ore prices and higher costs hit the result, and dividends are the lowest in eight years.
