Second Quarter Highlights

Second Quarter Review

Commenting on the Company’s second quarter results, Chairman and Chief Executive Officer Harris E. DeLoach, Jr. said, “Second quarter base earnings were essentially flat with last year, as our industrial and consumer businesses showed mixed results that were weaker than expected. Overall, volume growth was modest, and productivity improvements, while positive, were off our historical pace.

“Our industrial-focused businesses showed slightly improved operating profits, although business segment results were mixed. For instance, operating profits in our Tubes and Cores/Paper segment were essentially unchanged year over year for the second quarter. Productivity improvements, lower pension expenses and cost reductions in the segment were offset by a negative price/cost relationship stemming from higher recovered paper, energy, freight and other costs relative to the prior year due to the timing of contract resets. Volume was flat in the segment, and earnings were also negatively affected by the mix of business. All Other Sonoco, which consists primarily of industrial-related businesses, showed a 20 percent improvement in operating profits due primarily to productivity improvements.

“On the consumer side, operating profits from our Consumer Packaging segment declined 17 percent as a slight volume improvement and lower pension expenses were more than offset by a negative price/cost relationship, including the impact of higher energy and freight costs, and increased labor expenses. This setback was nearly offset by significantly improved results from our Packaging Services segment which benefitted from higher volume, particularly in our contract packaging operations.”

Second quarter GAAP net income attributable to Sonoco was $53.4 million, or $.52 per diluted share, in 2011, compared with $59.0 million, or $.58 per diluted share, in 2010. Base earnings were $60.8 million, or $.60 per diluted share, in the second quarter, compared with $60.6 million, or $.59 per diluted share, in 2010. 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.

Excluded from base earnings in the 2011 second quarter were $7.4 million, or $.08 per diluted share, in after-tax restructuring and other charges, largely attributable to the disposition of the Company’s Brazilian plastics operations and the announced closing of the Winnipeg, Manitoba, Canada, flexible packaging operation. After-tax restructuring charges of $1.6 million, or $.01 per diluted share, were excluded from base earnings in the 2010 quarter. Additional information about base earnings and base earnings per share, along with reconciliations to the most closely applicable GAAP financial measures, is provided later in this release.

Net sales for the second quarter were $1.13 billion, compared with $1.01 billion in the same period in 2010. This 12 percent increase was due to higher selling prices, acquisitions, favorable foreign currency translation and, to a lesser extent, improved volume, most notably in the Packaging Services segment. The impact of higher selling prices was realized primarily in the Tubes and Cores/Paper segment, principally driven by higher recovered paper prices.

The Company’s gross profit margin in the second quarter of 2011 was 16.9 percent of sales, compared with 19.1 percent in the same period in 2010. The decline was primarily due to a negative shift in the mix of business, a negative price/cost relationship, and higher labor and other costs. The Company’s selling and administrative costs were essentially unchanged year over year, but because of higher sales the ratio to sales declined to 8.8 percent, compared with 9.9 percent in the same period last year.

Cash generated from operations in the second quarter was $45.9 million, compared with $41.6 million generated in the same period in 2010. Capital expenditures and cash dividends were $41.9 million and $28.9 million, respectively, during the second quarter, compared with $30.5 million and $28.2 million, respectively, during the second quarter of 2010. Debt repayments totaled $31.6 million, and a total of $10.4 million was spent during the quarter to acquire a tubes and cores business in New Zealand and a rigid paper container business in the United Kingdom.

Year-to-date Results

For the first six months of 2011, net sales increased 15 percent to $2.25 billion, compared with $1.95 billion in the first half of 2010. Net income attributable to Sonoco for the first six months of 2011 was $110.8 million ($1.08 per diluted share), compared with $107.5 million ($1.05 per diluted share) in the same period in 2010. Earnings for the first half of 2011 were negatively impacted by after-tax restructuring and other charges of $8.5 million ($.09 per diluted share), compared with $4.1 million ($.04 per diluted share) in the same period in 2010.

Base earnings for the first half of 2011 were $119.3 million ($1.17 per diluted share), compared with $111.6 million ($1.09 per diluted share) in the same period in 2010. This 7 percent year-over-year improvement in base earnings was a result of productivity gains, higher Companywide volumes, primarily a result of six additional accounting days in the Company’s first quarter, and lower pension costs. These positive factors were partially offset by a negative mix of business and higher raw material, energy, freight and other costs. Gross profit as a percent of sales was 17.2 percent, compared with 18.9 percent in the first half of 2010.

For the first six months of 2011, cash generated from operations was $32.1 million, compared with $115.4 million in the same period in 2010. The year-over-year reduction in operating cash flow is due primarily to an $85 million contribution to the Company’s U.S. pension plan in the first quarter. Capital expenditures and cash dividends were $80.2 million and $57.0 million, respectively, for the first half of 2011, compared with $59.0 million and $55.2 million, respectively, in the same period in 2010. The Company also used $46.3 million in the first quarter of 2011 to repurchase common stock on the open market; there were no open-market repurchases in the second quarter or in the first half of 2010.

At the end of the second quarter of 2011, total debt was $736 million, an increase from $621 million at the end of 2010. The aforementioned pension contribution and share repurchases were primarily responsible for the increase. The Company’s debt-to-total-capital ratio was 31.5 percent, compared with 29.2 percent at the end of 2010. Cash and cash equivalents at the end of the second quarter totaled $134 million, compared with $158 million at year-end 2010.

Third Quarter and Full-Year 2011 Outlook

Sonoco expects third quarter 2011 base earnings to be in the range of $.64 to $.68 per diluted share. Base earnings in the third quarter of 2010 were a record $.65 per diluted share. For the full-year 2011, base earnings are projected to be in the range of $2.46 to $2.54 per diluted share. The Company had previously provided full-year guidance of $2.52 to $2.60 per diluted share. The Company’s 2011 earnings guidance reflects an expected effective tax rate of approximately 32 percent.

The Company’s base earnings guidance assumes sales demand will remain near the levels experienced during the past several quarters, adjusted for seasonality. Although the Company believes the assumptions reflected in the range of guidance are reasonable, given the volatility of recovered paper and other material prices, as well as uncertainty regarding the pace of any continued improvement in the economy, actual results could vary substantially.

Commenting on the Company’s outlook, DeLoach said, “Lingering unemployment, along with higher grocery and energy prices, have clearly impacted domestic consumer spending during the first half of 2011, which may have impacted volume and mix in certain of our consumer and industrial markets. While this consumer spending trend could continue into the second half, we hope to offset any attrition with new product sales, productivity improvements and cost controls. Our Packaging Services segment has shown improved results in the first half. However, we remain cautious going into the second half due to the previously announced loss of business in contract packaging. In addition, raw material inflation, particularly for recovered paper, may generate some headwind against our Tubes and Cores/Paper segment during the third quarter. Yet overall, we expect improved results in most of our consumer and industrial businesses in the second half, which should lead to record results for Sonoco in 2011.”

Segment Review

Segment operating results do not include restructuring and asset impairment charges, acquisition expenses, interest income and expense, income taxes or certain other items, if any, the exclusion of which the Company believes improves comparability and analysis.

Consumer Packaging

Sonoco’s Consumer Packaging segment includes the following products and services: round and shaped rigid containers and trays (both composite and plastic); printed flexible packaging; metal and peelable membrane ends and closures; and global brand artwork management.

Second quarter 2011 sales for the segment were $451 million, compared with $392 million in the same period in 2010. Segment operating profit was $35.0 million in the second quarter, compared with $42.1 million last year.

Sales increased by 15 percent during the second quarter due to last year’s acquisition of Associated Packaging Technologies, Inc., a leading thermoformed tray manufacturer for the frozen food industry, higher selling prices and favorable currency translation. Volume growth in flexible packaging and rigid plastic containers was partially offset by declines in rigid paper containers and closures. Operating profits declined 17 percent from the previous year’s results due to a negative price/cost relationship, a change in the mix of business and higher labor costs.

Tubes and Cores/Paper

The Tubes and Cores/Paper segment includes the following products: high-performance paper and composite paperboard tubes and cores; fiber-based construction tubes and forms; recycled paperboard, linerboard, corrugating medium, recovered paper and other recycled materials.

Second quarter 2011 sales for the segment were $456 million, compared with $416 million in the same period in 2010. Segment operating profit was $37.3 million, compared with $36.9 million in 2010.

The 10 percent increase in segment sales was due to higher selling prices and favorable currency translation. The year-over-year increase in selling prices was primarily a result of higher old corrugated containers pricing, which had a favorable impact on prices received for recovered paper, paperboard, and tubes and cores, and resulted in a flat price/cost relationship.

Operating profit for the segment was essentially unchanged compared to the prior year period. Productivity improvements, lower pension expense and cost reductions were offset by a negative price/cost relationship relative to the prior year, partially due to the timing of contract resets, and a change in the mix of business.

Packaging Services

The Packaging Services segment includes the following products and services: designing, manufacturing, assembling, packing and distributing temporary, semipermanent and permanent point-of-purchase displays; and supply chain management services, including contract packing, fulfillment and scalable service centers.

Second quarter 2011 sales for this segment were $124 million, compared with $114 million in the same period in 2010. Segment operating profit was $8.2 million, compared with $3.6 million in 2010.

The quarter’s 9 percent sales improvement was driven by improved volume in contract packaging and point-of -purchase displays and favorable currency translation. Operating profit for the segment more than doubled due to improved volume.

All Other Sonoco

All Other Sonoco includes businesses that are not aggregated in a reportable segment, and includes the following products: wooden, metal and composite wire and cable reels and spools; molded and extruded plastics; custom-designed protective packaging; and paper amenities, such as coasters and glass covers.

Second quarter 2011 sales in All Other Sonoco were $97 million, compared with $88 million in the same period in 2010. Operating profit for the quarter was $12.3 million, compared with $10.3 million in 2010.

Sales in All Other Sonoco increased 10 percent due to volume gains in molded plastics and reels and spools, higher selling prices and sales from a small acquisition. Operating profit in All Other Sonoco increased 20 percent primarily as a result of productivity gains.

Corporate

Net interest expense for the second quarter of 2011 decreased slightly to $8.2 million, compared with $8.6 million during the same period in 2010. The effective tax rate for the second quarter of 2011 was 32.1 percent, compared with 31.6 percent for the same period in 2010. The effective tax rate on base earnings was 31.9 percent and 31.8 percent in the second quarters of 2011 and 2010, respectively. The effective tax rate on base earnings for the current quarter is higher than the same period last year, primarily as a result of a larger proportion of earnings taxed at higher U.S. rates.

Definition and Reconciliation of Non-GAAP Financial Measures

The Company’s results determined in accordance with U.S. generally accepted accounting principles (GAAP) are referred to as “as reported” results. Some of the information presented in this press release reflects the Company’s “as reported” results adjusted to exclude amounts related to restructuring initiatives, asset impairment charges, environmental charges, acquisition costs, losses from the early extinguishment of debt, and certain other items, if any, the exclusion of which management believes improves comparability and analysis of the underlying financial performance of the business. These adjustments result in the non-GAAP financial measures referred to in this press release as “Base Earnings” and “Base Earnings per Diluted Share.”

These non-GAAP measures are not in accordance with, or an alternative for, generally accepted accounting principles and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Sonoco continues to provide all information required by GAAP, but it believes that evaluating its ongoing operating results may not be as useful if an investor or other user is limited to reviewing only GAAP financial measures. Sonoco uses these non-GAAP financial measures for internal planning and forecasting purposes, to evaluate its ongoing operations, and to evaluate the ultimate performance of each business unit against budget all the way up through the evaluation of the Chief Executive Officer’s performance by the Board of Directors. In addition, these same non-GAAP measures are used in determining incentive compensation for the entire management team and in providing earnings guidance to the investing community.

Sonoco management does not, nor does it suggest that investors should, consider these non-GAAP financial measures in isolation from, or as a substitute for, financial information prepared in accordance with GAAP. Sonoco presents these non-GAAP financial measures to provide users information to evaluate Sonoco’s operating results in a manner similar to how management evaluates business performance. Material limitations associated with the use of such measures are that they do not reflect all period costs included in operating expenses and may not reflect financial results that are comparable to financial results of other companies that present similar costs differently. Furthermore, the calculations of these non-GAAP measures are based on subjective determinations of management regarding the nature and classification of events and circumstances that the investor may find material and view differently. To compensate for these limitations, management believes that it is useful in understanding and analyzing the results of the business to review both GAAP information, which includes all of the items impacting financial results, and the non-GAAP measures that exclude certain elements, as described above. Whenever Sonoco uses a non-GAAP financial measure, it provides a reconciliation of the non-GAAP financial measure to the most closely applicable GAAP financial measure. Whenever reviewing a non-GAAP financial measure, investors are encouraged to fully review and consider the related reconciliation as detailed below.
