FOR IMMEDIATE RELEASE

BEMIS COMPANY REPORTS 2011 FIRST QUARTER RESULTS

NEENAH, WISCONSIN, April 28, 2011 — Bemis Company, Inc. (NYSE-BMS) today reported its 2011 first quarter results:

Highlights of the first quarter 2011:

·                  First quarter net sales increased to a record $1.3 billion.

·                  Flexible packaging segment operating profit was negatively impacted by higher raw material costs in advance of selling price adjustments.

·                  Diluted earnings for the first quarter was $0.47 per share as compared to management’s first quarter 2011 guidance of $0.50 to $0.55 per share.

·                  Bemis’ quarterly dividend increased by 4.3 percent, from $0.23 per share to $0.24 per share.

·                  Repurchases of Bemis common stock during the quarter totaled 1.7 million shares.

·                  Management established earnings guidance for the second quarter of 2011 at $0.48 to $0.54 per share, and total year 2011 earnings guidance was reduced to $2.15 to $2.30 per share to reflect the expected impact of raw material cost changes on the first half of the year.

“Increasing raw material costs have created a challenging environment for our flexible packaging business,” said Henry Theisen, Bemis Company’s President and Chief Executive Officer.  “I am pleased to report that we are growing sales volumes in our targeted product categories, and we are on track with our plan to optimize our manufacturing platforms by concentrating the production of certain products in the most profitable location for such processes.  Unfortunately, raw material cost increases for specialty resins were more dramatic than we had anticipated.  In addition, the price adjustment formulas in the customer agreements that we acquired with the Food Americas business delay selling price increases beyond our normal policy timeframes.  This decreased margins during the first quarter and reduced our profit expectations for the second quarter.  By the third quarter of 2011, we expect operating profit to begin to improve as most selling prices should be adjusted to reflect the impact of the raw material cost increases earlier in the year.”

CONSOLIDATED RESULTS

Total Bemis net sales were $1.3 billion for the first quarter of 2011, a 30 percent increase from $1.0 billion for the same period of 2010.  The March 1, 2010 acquisition of Alcan Packaging Food Americas business increased first quarter net sales by an estimated 19 percent.  The remaining sales growth included a 2 percent increase from currency effects.

Diluted earnings per share for the first quarter of 2011 were $0.47 compared to diluted earnings from continuing operations of $0.27 per share reported in the same quarter of 2010.  Excluding the effect of acquisition-related charges and pre-acquisition financing impacts, as detailed in the attached schedule, “Reconciliation of Non-GAAP Data,” diluted earnings per share from continuing operations, as adjusted, would have been $0.48 for the first quarter of 2010.  Performance for the first quarter of 2011 was negatively impacted by increases in the cost of specialty resin raw materials which began during the fourth quarter of 2010 and are expected to continue through the second quarter of 2011.

FLEXIBLE PACKAGING BUSINESS SEGMENT

Bemis’ flexible packaging business segment reported net sales of $1.2 billion.  This represents a 34 percent increase compared to net sales of $881.4 million for the first quarter of 2010.  Bemis estimates that the acquisition of the Food Americas business on March 1, 2010 resulted in an increase in net sales of approximately 22 percent during the quarter.  Currency effects increased net sales by 3 percent.  The remaining sales growth reflects higher selling prices coupled with increased unit sales volume and improved sales mix.  Segment operating profit for the first quarter of 2011 was $116.3 million, or 9.9 percent of net sales,

compared to $93.9 million, or 10.7 percent of net sales, for the same period of 2010.  During the first quarter of 2010, adjustments related to the March 2010 Food Americas acquisition negatively impacted results.  Segment operating profit, as adjusted, for the first quarter would have been $105.9 million, or 12.0 percent of net sales, in 2010.  (See attached schedule: “Reconciliation of Non-GAAP Data.”)  The effect of currency translation increased operating profit in the first quarter of 2011 by $2.0 million compared to the same quarter of 2010.  Dramatic raw material cost increases that began during the fourth quarter of 2010 have negatively impacted operating profit for the first quarter of 2011.

Commenting on the flexible packaging segment results, Theisen said, “This quarter we experienced encouraging sales growth from new business and improved sales mix, while raw material cost increases reduced operating profit in advance of selling price adjustments.  Healthy unit volume growth in value-added packaging for markets such as meat and cheese, dry foods, and specialty food products is building momentum for improved sales mix in 2011.  At the same time, many of our customers are expressing caution about future order volumes.  Food price inflation has caused retail consumer prices to increase, which may result in lower consumer demand for some packaged food products.  As a result, a higher percentage of our unit sales growth is expected to come from new business in the first half of 2011.  In Europe, unit volumes have stabilized but competition remains strong in this environment of higher raw material costs.  Our Brazilian operations continue to perform well, but volume growth has slowed as the strong Brazilian currency has reduced export demand for our customers’ products.

“Both specialty and commodity raw material costs have been increasing steadily since the fourth quarter of 2010.  Recently, more dramatic raw material cost increases have occurred, magnifying the importance of the speed at which selling prices can be adjusted.  As we noted last quarter, the price adjustment formulas in our customer agreements allow for selling price adjustments on a fixed time schedule.  The customer agreements we inherited in the 2010 Food Americas acquisition generally included longer selling price adjustment timeframes which, when combined with typical Bemis customer agreements, have increased our average selling price adjustment period.  We expect this to delay our ability to adjust for some of the recent, dramatic cost increases until the third quarter of this year.”

PRESSURE SENSITIVE MATERIALS BUSINESS SEGMENT

Net sales from the pressure sensitive materials business segment for the first quarter of 2011 were $145.0 million, a 3.3 percent increase compared to $140.3 million in the first quarter of 2010.  For the first quarter of 2011, the benefits of higher selling prices in line with raw material cost increases and prudent cost management led to operating profit of $9.9 million, or 6.8 percent of net sales, compared to operating profit for first quarter of 2010 of $6.6 million, or 4.7 percent of net sales.  Currency effects were insignificant to net sales and operating profit for the quarter.

OTHER OPERATING (INCOME) EXPENSE, NET

For the first quarter of 2011, other operating income and expense included $5.5 million of fiscal incentive income, an increase of $1.8 million compared to $3.7 million for the first quarter of 2010.  Fiscal incentives are associated with net sales and manufacturing activities in certain South American operations and are included in flexible packaging segment operating profit.  Other operating income and expense for the first quarter of 2010 also included $12.7 million of professional fees associated with the acquisition of the Food Americas business.

OTHER NON-OPERATING (INCOME) EXPENSE, NET

For the first quarter of 2011, other non-operating income and expense included net foreign exchange losses of $2.0 million compared to net foreign exchange gains in the first quarter of 2010 of $2.5 million, primarily reflecting the net impact of currency fluctuations on financing arrangements for the foreign operations acquired in the 2010 Food Americas acquisition.

CAPITAL STRUCTURE AND CASH FLOW

Net debt to total capitalization was 41 percent at March 31, 2011, compared to 39 percent at December 31, 2010.  Total debt as of March 31, 2011 was $1.4 billion, an increase of $134 million from the balance of $1.3 billion at December 31, 2010.  Higher cost raw materials increased inventory levels and higher selling prices increased accounts receivable during the first quarter.  The increase in outstanding debt reflects the use of cash to support these higher levels of working capital, as well as open market purchases of 1.7 million shares of Bemis common stock.  The remaining share repurchase authorization as of March 31, 2011 was 7.9 million shares.

2011 EARNINGS OUTLOOK

Commenting on the outlook for the rest of the year, Theisen said, “While we anticipated increasing raw material costs during the first half of 2011, recent political events and supply shortages have increased the speed and magnitude of specialty resin cost increases.  As a result, flexible packaging operating profits during the second quarter of 2011 are expected to be more negatively impacted than we originally anticipated.  Operating results for the second half of the year are expected to improve as most selling prices will have been adjusted to reflect these raw material cost increases, and we expect to benefit from production efficiencies resulting from optimization initiatives.”

Management expects adjusted diluted earnings per share for the second quarter of 2011 to be in the range of $0.48 to $0.54.  In light of the anticipated results for the first half of 2011 and the assumption that raw material costs will stabilize and not decrease during this year, management expects adjusted diluted earnings per share for the full year 2011 to be in the range of $2.15 to $2.30 per share.  Capital expenditures are expected to be approximately $150 million for the full year 2011.
