Jan 25, 2012. /Lesprom Network/. RockTenn reported that its 1Q net income to shareholders increased to $76.7 million from $50.3 million last year. Earnings per share was $1.06 compared to $1.27 prior year. Net sales of $2,267.7 million for the 1Q of fiscal 2012 increased $1,506.6 million over the 1Q of fiscal 2011, primarily as a result of the May 27, 2011, Smurfit-Stone acquisition, as the company said in a press release received by Lesprom Network. Segment income, adjusted to eliminate $0.4 million of pre-tax acquisition inventory step-up, was $193.5 million, up 74.8% over the prior year quarter, primarily as a result of the Smurfit-Stone acquisition. RockTenn’s restructuring and other costs and operating losses and transition costs due to plant closures, net of related noncontrolling interest were $0.12 per diluted share after-tax, for the first quarter of fiscal 2012. These costs consisted primarily of $3.6 million of pre-tax facility closure charges primarily related to former Smurfit-Stone corrugated container plants, $7.3 million of pre-tax integration and acquisition costs that primarily consisted of professional services and other employee costs and $1.6 million of pre-tax operating losses and transition costs in connection with consolidating converting facilities. RockTenn Chairman and CEO James A. Rubright stated, “Our adjusted earnings of $1.18 per share reflect continued earnings accretion from the Smurfit-Stone acquisition, which we estimate at $.15 for the quarter and $1.03 for the seven months since we completed the acquisition. Our earnings were lower than the prior quarter due to the combination of normal seasonal volume and mix trends, major maintenance outage expenses and very competitive export containerboard markets and domestic box markets.” RockTenn is one of North America's leading integrated manufacturers of corrugated and consumer packaging and recycling solutions.
