Key metrics from Caterpillar’s earnings report

Caterpillar’s net earnings were $1.23 per share, compared to $1.54 per share last year. The company’s net earnings include costs related to restructuring.

Caterpillar reported record sales and profits in its Energy & Transportation segment and increases in both metrics in its Construction Industries segment. Falling prices for commodities, especially copper, iron ore and coal, dragged the company’s Resources Industries results lower in the quarter, resulting in Caterpillar missing its fourth quarter profit guidance.

Management expects sales for this year to be approximately $50 billion, which is significantly lower than the FactSet consensus estimate of $54.83 billion. They project profits of this year to be approximately $4.60 per share. Excluding restructuring costs, they’re expecting earnings of about $4.75 per share.

Earlier this month, Jim Chanos disclosed his bearish stance on Caterpillar, announcing that he was shorting the company’s stock.
