Compass Minerals International Inc. reported record earnings in its second quarter, despite lower revenue compared with the same period last year.

In a release after the market closed on Tuesday, the Overland Park-based company (NYSE: CMP) reported earnings of $14.1 million, or 42 cents a share, for the quarter that ended June 30. This compares with earnings of $1.6 million, or 5 cents a share, last year.

Revenue for the quarter was $159.5 million, down 1.5 percent from $162 million last year, due in part to decreased specialty fertilizer sales volume.
