Illinois-based ADM reported net earnings of $533 million, or 81 cents per share, up from $223 million, or 34 cents a share, a year earlier.

Adjusted earnings rose to 77 cents per share from 46 cents. Analysts on average had expected 73 cents, according to Thomson Reuters I/B/E/S.

Revenue was $21.5 billion, down from $22.5 billion a year earlier.
