Plastic Products

Second quarter revenue increased 13% to $130 million compared to $116 million in the prior year’s quarter, with growth driven by higher volume and favorable product mix, the benefit from the pass through of higher resin costs in customer selling prices and favorable foreign exchange translation.

Segment adjusted EBITDA for the 2011 quarter increased 3% to $11.2 million compared to $10.9 million in the prior year’s second quarter due to the higher volume, partially offset by product mix and the impact of higher resin costs, increasing costs of sales. Increased resin costs were not yet reflected in higher customer selling prices; Plastics adjusts customer selling prices based on underling resin costs on a delayed basis.

Balance Sheet and Capital Expenditures

The Company had cash and equivalents as of March 31, 2011 of $208 million and total debt outstanding was $676 million. Capital expenditures in the second quarter were $24 million. Griffon continues to expect capital spending in 2011 will approximate $60 - $70 million.
