Sep 10, 2012. /Lesprom Network/. Sonoco announced revised base earnings guidance for the 3Q ending September 30, 2012. The Company expects 3Q 2012 base earnings per diluted share to be $.51 to $.53, compared with previously announced guidance of $.62 to $.66 per diluted share. The Company reported base earnings of $.66 per diluted share in the 3Q 2011. Base earnings and base earnings per diluted share are non-GAAP financial measures adjusted to remove restructuring charges, asset impairment charges and other items, if any, the exclusion of which the Company believes improves comparability and analysis of the underlying financial performance of the business. The revision of 3Q estimates is primarily due to operating problems experienced at several of the Company's North American uncoated recycled paperboard mills which have led to unscheduled downtime and related excess costs. In addition, the Company is experiencing lower than anticipated volumes in many of its consumer and industrial packaging businesses. As a result, Sonoco has removed its base earnings estimates for full-year 2012 and plans to provide updated guidance for the 4Q and 2012 when it releases 3Q results before the market opens on October 18, 2012. Sonoco's 3Q is not yet completed and as a result the financial estimates provided in this release are subject to change based on actual results through the end of the third quarter, the closing of Sonoco's books and determination of actual financial results. Sonoco will host its regular quarterly conference call on Thursday, October 18, 2012, at 11 a.m. ET, to review its 3Q 2012 financial results. Sonoco is a global provider of a variety of consumer packaging, industrial products, protective packaging and packaging supply chain services.
