Third Quarter Highlights

Third Quarter Review

Commenting on the Company’s third quarter results, Chairman and Chief Executive Officer Harris E. DeLoach, Jr. said, “Despite slowing global economic conditions, our third quarter base earnings were essentially flat with last year and up 10 percent from the second quarter of 2011. Compared to the prior year third quarter, volume declined slightly, particularly in our more economic-sensitive industrial businesses, and we continued to see a negative mix in many of our businesses. Even though we faced raw material, energy and freight cost headwinds, the price/cost relationship for the quarter was only slightly negative. We were helped by productivity improvements, although not up to our historic levels, and lower selling and administrative costs.

“Our Consumer Packaging segment’s operating profits were 35 percent higher, when compared to the second quarter and slightly better than last year’s third quarter. Improved productivity, volume gains and cost reduction efforts offset a negative price/cost relationship. In our Packaging Services segment, results were up year over year; however, results were down sequentially from the second quarter as improved point-of-purchase display volume and fulfillment activities could not offset previously announced lost contract packaging business.

“Our industrial-focused businesses had mixed results, as our Tubes and Cores/Paper segment’s third quarter operating profits were down 10 percent year over year and 9 percent sequentially. Results for the quarter were impacted by lower global volume for tubes and cores along with an unfavorable mix of business. These negative factors were partially offset by productivity improvements. All Other Sonoco, which primarily includes industrial-related businesses, showed a 6 percent improvement in operating profits year over year and a 7 percent improvement sequentially, due primarily to productivity.”

Sonoco Reports 2011 Third Quarter Results – page 2

Third quarter GAAP net income attributable to Sonoco was $77.2 million, or $.76 per diluted share, in 2011, compared with $59.0 million, or $.57 per diluted share, in 2010. Base earnings were $67.1 million, or $.66 per diluted share, in the third quarter of 2011, compared with $67.1 million, or $.65 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.

Items excluded from base earnings in the 2011 third quarter include: a net $18.8 million, or $.18 per share, reduction in tax expense resulting from valuation allowance adjustments on deferred tax assets; restructuring expenses of $7.2 million, after tax, or $.07 per share, primarily due to the closures of a tubes and cores plant and a plastics facility; and acquisition-related costs of $1.5 million, after tax, or $.01 per share. Excluded from base earnings in the third quarter of 2010 were impairment and restructuring charges of $6.9 million, after tax, or $.07 per share, primarily related to impairment charges in the Company’s Flexible Packaging unit, and $1.1 million, after tax, or $.01 per share, in acquisition-related costs.

Net sales for the third quarter were $1.12 billion, compared with $1.05 billion in the same period in 2010. This 7 percent increase was due to higher selling prices and favorable foreign currency translation, partially offset by a negative mix of business. The impact of higher selling prices was realized primarily in the Tubes and Cores/Paper and Consumer Packaging segments, principally driven by higher recovered paper and resin prices.

The Company’s gross profit margin in the third quarter of 2011 was 16.6 percent of sales, compared with 19.0 percent in the same period in 2010. The decline was primarily due to lower volume, a negative shift in the mix of business and higher labor and other costs. The Company’s selling and administrative costs declined 12 percent year over year, primarily due to lower management incentive and pension costs, a gain from life insurance proceeds, cost controls and the net impact of foreign exchange.

Cash generated from operations in the third quarter was $100 million, compared with $145 million generated in the same period in 2010. Capital expenditures and cash dividends were $44 million and $29 million, respectively, during the third quarter, compared with $42 million and $28 million, respectively, during the third quarter of 2010.

Year-To-Date Results

For the nine-month period ending October 2, 2011, net sales increased 12 percent to $3.37 billion, compared with $3.0 billion in the same period of 2010. Net income attributable to Sonoco for the first nine months of 2011 was $188 million ($1.84 per diluted share), compared with $166.5 million ($1.63 per diluted share) in the same period in 2010. Earnings for the nine-month period of 2011 include a net positive impact of $1.5 million, after tax, or $.02 per diluted share, due to the previously mentioned net favorable deferred tax asset adjustments more than offsetting restructuring and acquisition costs. This is compared with a negative impact of $12.1 million, after tax, or $.12 per diluted share, for restructuring and other charges in the same period in 2010.

Year-to-date base earnings were $186.5 million ($1.82 per diluted share), compared with $178.6 million ($1.75 per diluted share) in the same period in 2010. This 4 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 17.0 percent for the nine-month period, compared with 18.9 percent in 2010.

For the first nine months of 2011, cash generated from operations was $132 million, compared with $261 million in the same period in 2010. Higher pension and postretirement plan contributions account for approximately $105 million of the year-over-year decrease, including an $85 million contribution to the Company’s U.S. pension plan made in the first quarter of 2011. Capital expenditures and cash dividends were $124 million and $86 million, respectively, for the nine months of 2011, compared with $101 million and $83 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, while there were no open-market share repurchases in the first nine months of 2010. The Company spent a total of $10.9 million on acquisitions in the first nine months of 2011, compared with $134.3 million spent in 2010.

At the end of the third quarter of 2011, total debt was $735 million, an increase from $621 million at the end of 2010. The aforementioned pension contributions and share repurchases were primarily responsible for the increase. The Company’s debt-to-total-capital ratio was 32.2 percent, compared with 29.2 percent at the end of 2010. Cash and cash equivalents at the end of the third quarter totaled $146 million, compared with $158 million at year-end 2010.

Fourth Quarter and Full-Year 2011 Outlook

Sonoco expects fourth quarter 2011 base earnings to be in the range of $.59 to $.63 per diluted share. Base earnings in the fourth quarter of 2010 were $.59 per diluted share. For the full-year 2011, base earnings are projected to be in the range of $2.41 to $2.45 per diluted share. The Company had previously provided full-year guidance of $2.46 to $2.54 per diluted share. The Company’s earnings guidance for the fourth quarter reflects six fewer days than last year’s final quarter and an expected effective tax rate of approximately 32.3 percent.

The Company’s base earnings guidance assumes sales demand will remain near current levels, 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 global economy, actual results could vary substantially.

Commenting on the Company’s outlook, DeLoach said, “We have become more cautious about global economic conditions and the direction of consumer spending. For that reason, we are moving guidance to reflect the gradual slowing that we are seeing in our served markets, particularly in our industrial markets. In response, the Company is continuing to place restrictions on spending and taking proactive measures to further reduce costs.

“A key focus in the fourth quarter will be closing the recently announced $550 million acquisition of Tegrant Corporation. Closing on the transaction is expected to occur in mid-November and the impact on 2011 base earnings is not expected to be significant. We expect to incur non-base transaction costs of approximately $6 million, excluding financing costs, which will be expensed after closing. A joint integration team has been identified and will begin working after the closing to quickly bring our businesses together and realize identified synergies.”

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.

Third quarter 2011 sales for the segment were $466 million, compared with $437 million in the same period in 2010 and $451 million in the second quarter of 2011. Segment operating profit was $47.2 million in the third quarter, compared with $46.3 million last year and $35 million in the second quarter.

Sales increased by 7 percent during the third quarter over the prior year period, due to higher selling prices, and to a lesser extent, volume growth in flexible packaging and rigid plastic containers and favorable currency translation. Operating profits improved 2 percent from the previous year’s results, due to volume growth, productivity improvements and lower pension, and selling and administrative expenses. These positive factors were offset by a negative price/cost relationship and a change in the mix of business.

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.

Third quarter 2011 sales for the segment were $453 million, compared with $412 million in the same period in 2010 and $456 million in the second quarter of 2011. Segment operating profit was $33.9 million, compared with $37.8 million in 2010 and $37.3 million in the second quarter.

The 10 percent year-over-year increase in third quarter segment sales was due to higher selling prices and favorable currency translation. The 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.

Operating profit for the segment declined 10 percent, compared with the prior-year period and was down 9 percent from the second quarter. A decline in global volume, a negative mix of business, wage inflation and a slightly negative price/cost relationship more than offset productivity improvements and lower pension, and selling and administrative expenses.

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.

Third quarter 2011 sales for this segment were $111 million, compared with $112 million in the same period in 2010 and $124 million in the second quarter of 2011. Segment operating profit was $4.2 million, compared with $1.9 million in 2010 and $8.2 million in the second quarter.

Improvement in point-of-purchase display volume and fulfillment activities and favorable currency translation in the third quarter were offset by the previously disclosed loss of a contract packaging customer. Operating profit for the segment more than doubled due to operating cost improvements and lower selling and administrative expenses.

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.

Third quarter 2011 sales in All Other Sonoco were $94 million, compared with $91 million in the same period in 2010 and $97 million in the second quarter of 2011. Operating profit for the current quarter was $13.2 million, compared with $12.5 million in 2010 and $12.3 million in the second quarter.

Sales in All Other Sonoco increased 4 percent in the third quarter, year over year, due to higher selling prices, volume gains in molded plastics and reels and spools, and favorable currency translation, partially offset by lower volume in protective packaging. Operating profits in All Other Sonoco increased 6 percent, primarily as a result of productivity gains, positive price/cost, and lower selling and administrative costs, which more than offset a negative impact from volume and mix.

Corporate

Net interest expense for the third quarter of 2011 decreased slightly to $8.3 million, compared with $8.4 million during the same period in 2010. The effective tax rate for the third quarter of 2011 was 3.1 percent, compared with 27.6 percent for the same period in 2010, reflecting the net benefit of the deferred tax asset adjustments referred to above. The effective tax rate on base earnings was 29.1 percent and 29.6 percent in the third quarters of 2011 and 2010, respectively.

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” or “GAAP” results. Some of the information presented in this press release reflects the Company’s “as reported” or “GAAP” 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.
