Aptargroup Achieves Record Fourth Quarter Results and Completes Strongest Year Ever

CRYSTAL LAKE, Ill.--(BUSINESS WIRE)--February 10, 2011--Aptargroup, Inc. (NYSE:ATR) today reported record fourth quarter and annual sales and earnings per share.

Fourth Quarter 2010 Summary

• Results surpassed last year’s record levels
• Sales, driven by growth across each segment, up 11% before currency effects
• Higher custom tooling sales contributed 3% to the top line
• Demand increased from the fragrance/cosmetic, food/beverage, and pharma markets
• Demand for dispensing closures from the personal care market decreased
• Reported diluted earnings per share increased 13% to record $.59

FOURTH QUARTER RESULTS

For the quarter ended December 31, 2010, reported sales increased 7% to $530.8 million from $495.6 million a year ago despite the negative effects of changes in currency rates.

Commenting on the quarter, Peter Pfeiffer, President and CEO, said, “We were up against a difficult comparison to our record fourth quarter of 2009 results but we surpassed those results on the strength of our broad product portfolio and the diversity of markets we serve. Our Beauty & Home segment posted strong sales in the quarter particularly due to increased demand from the fragrance/cosmetic market. Our Pharma segment sales also improved year over year mainly driven by increased custom tooling sales and improved demand for metered valves. Our Closures segment sales were positively impacted by strong demand from the food/beverage market as well as higher custom tooling sales and resin price adjustments. These positive effects were partially offset by weaker demand for dispensing closures from the personal care market."

Pfeiffer continued, “Improved sales and profits in our Beauty & Home and Pharma segments drove our record fourth quarter earnings. We continued to capitalize on improved productivity resulting from strong demand and our cost containment efforts. Closures segment income declined from the prior year primarily due to the decreased demand from the personal care market and operational challenges caused by a high level of new project activity. Consolidated operating income rose to $61.2 million, up 8% over the prior year level of $56.9 million (which included approximately $1.8 million of consolidation/severance expenses). Reported diluted earnings per share increased 13% to a record $.59 per share, compared to $.52 per share in the prior year. Prior year earnings per share included the negative effect of $.02 per share from charges related to our consolidation/severance program.”

ANNUAL RESULTS

Pfeiffer stated, “This proved to be an exceptional year for our company especially after following one of the most challenging years in our history. Throughout 2009, we took steps to reduce costs without jeopardizing key capacity and we were well positioned coming into 2010 to meet the recovery in demand, particularly from our Beauty & Home and Closures customers. Also, our Pharma segment posted another solid year of consistent growth, leading the nasal and pulmonary delivery device industry. We achieved record consolidated sales and profits by remaining focused on our customers’ needs, investing in research and development, implementing new technologies, and allowing for growth while closely monitoring our cost structure. We accomplished all of this even as we undertook a strategic step to further align our businesses with the markets we serve.”

Year-to-date sales increased 13% to $2.1 billion from $1.8 billion a year ago. Changes in exchange rates negatively affected the sales growth by approximately 1%. Operating income increased to a record $268 million, up 35% from $198.4 million a year ago (which included approximately $7.6 million of consolidation/severance expenses). Reported diluted earnings per share increased 39% to a record $2.48 per share compared to $1.79 per share a year ago. Prior year earnings per share included a negative effect of $.07 per share from charges related to the Company’s consolidation/severance program.

Aptargroup spent approximately $86 million to repurchase approximately 2 million shares of common stock in 2010, leaving approximately 1.7 million shares authorized for repurchase at the end of the year. Also during the year, a total of $44.5 million was paid to stockholders in the form of dividends, or $.66 per share. This reflects the 20% increase in the quarterly dividend approved by the Board in July of 2010.

OUTLOOK

Pfeiffer commented, “We are confident that our strategically aligned businesses will continue to grow in 2011. While we experienced exceptional growth in 2010, we anticipate that generally our segments will reflect more normalized growth rates going forward. Though several challenges lie ahead, including rising input costs and our ability to pass through such increases in a timely manner, we have faced similar challenges in the past. Our financial condition is as strong as it has ever been, and we remain committed to investing in new technologies and new products. Our strategy is to continue to probe deeper into our markets to tap underserved sectors, to get even closer to our customers and help them grow their brands, and to better understand the needs of end consumers in order to provide them with the world’s most innovative dispensing solutions. As we look to the first quarter of 2011, we expect diluted earnings per share to be in the range of $.60 to $.65 per share compared to $.56 per share reported last year.”
