However, after adjustments that included the value of recently acquired Rockwood Holdings’ inventory, Albemarle turned a profit of $95.1 million, or 84 cents per share, compared to $86.8 million, or $1.10 per share, a year ago.

Stock analysts surveyed by Zacks Investment Research had forecast earnings of 82 cents per share.

Albemarle reported net sales of $931.5 million in the second quarter, compared to $604.7 million a year earlier. The increase was driven primarily by Rockwood.
