Greif, Inc. Revises Fiscal 2012 Guidance

DELAWARE, Ohio (Aug. 15, 2012) – Greif, Inc. (NYSE:GEF, GEF.B) today announced revised guidance for fiscal 2012, which ends on Oct. 31, 2012. EBITDA (earnings before interest, taxes, depreciation and amortization) is expected to be $445 million - $465 million compared with the company’s previous guidance of $500 million - $525 million. This decrease is primarily due to lower than expected volumes.

Third quarter 2012 volumes for the company’s rigid industrial packaging and flexible products businesses were below expectations primarily due to softer than anticipated market conditions. While there are some signs of market firming in Europe, it is occurring at a slower pace than the company expected earlier this year, and it appears that rigid packaging markets in other regions of the world are now being impacted. In addition, the geographic mix of earnings will result in a higher book tax rate for third quarter 2012 than the company had previously anticipated.

The economic conditions noted above are expected to also impact fourth quarter 2012 results and have been included in this revised fiscal 2012 guidance.

Management believes that the company will continue to generate sufficient operating cash flow to support quarterly cash dividends consistent with past practice and reinvestment in the business.

The company plans to report its third quarter 2012 financial results on Aug. 29, 2012, following the market close. A conference call is planned for Aug. 30, 2012, at 10:00 a.m. Eastern Time to discuss those results.
