STEPAN REPORTS RECORD QUARTERLY EARNINGS

EARNINGS, EXCLUDING DEFERRED COMPENSATION, UP 30 PERCENT

NORTHFIELD, Illinois, April 24, 2012 -- Stepan Company (NYSE: SCL) today reported record first quarter earnings for the period ended March 31, 2012.

• Net income rose 19 percent to $22.3 million compared to $18.8 million a year ago.
• Net income, excluding deferred compensation expense, rose 30 percent to $23.6 million compared to $18.2 million a year ago.
• Net sales increased 10 percent to $465.3 million on volume growth of 4 percent. Higher selling prices attributable to commodity raw material inflation also contributed to the increase.

The increase in sales was primarily due to higher selling prices and sales volume.

• Surfactant sales volume rose 4 percent. North America and Europe each recorded a 3 percent increase in volume, while Latin American volume rose 6 percent. Volume growth in Brazil accounted for a majority of the Latin American increase. Improved volume of functional surfactants used in agricultural, oilfield and biodiesel led the growth in North American volume. Sales of Consumer Products led the volume growth in Europe and Latin America.
• Polymer sales volume grew by 7 percent. Sales volume of polyol, used primarily in rigid foam insulation, grew by 9 percent due to higher demand for insulation in replacement roofing and new demand in metal panel insulation and adhesive applications.
• Specialty Products net sales rose by 89 percent for the quarter as a result of increased sales, attributable to the Company’s 2011 acquisition of the Lipid Nutrition product lines.

Gross profit increased by 24 percent to a record $76.8 million for the quarter.

• Surfactant gross profit grew by 14 percent to $54.0 million. Higher sales volume, improved product mix and the continuing recovery of higher raw material costs in selling prices all contributed to the improvement. North America, Europe and Latin America all posted improved earnings.
• Polymer gross profit grew by 57 percent to $17.4 million. The growth was led by increased demand for polyol in Europe (volume rose 12 percent) and North America (volume rose 7 percent). Selling price increases to recover higher raw material costs contributed to the improvement.
• Specialty Products gross profit rose 57 percent to $6.3 million. The improvement was largely attributable to the Lipid Nutrition product lines acquired in June of 2011.

The $9.5 million, or 30 percent, increase in operating expenses includes:

The remaining increase of $2.7 million relates to headcount additions to support global growth initiatives coupled with routine wage increase.

The effective tax rate was 31.7 percent for the first quarter of 2012 compared to 30.7 percent for the first quarter of 2011. The increase was primarily attributable to lower projected tax credits available in the United States, as Congress has not yet reenacted the research and development credit.

The balance sheet remains strong and will facilitate our strategy to invest in growth opportunities. Capital expenditures during the quarter were $21.3 million.

Our strong first quarter results reaffirm our strategy for growth from both global expansion and higher value added products. All three segments delivered record first quarter profits. Our Surfactant business experienced continued growth in higher value functional surfactants used in agricultural and oilfield products. Our expansion efforts in Brazil delivered solid earnings growth. The Singapore methyl ester plant is just coming on line and should begin shipping product during the second quarter.

The Polymer segment delivered a record first quarter on continued growth of its polyol product used in rigid foam insulation. Our polyol plant expansion in Germany is operational. This new capacity will meet anticipated sales growth for the region. Our PA/Polyol plant will complete its triennial maintenance shutdown in North America in the second quarter.

The Lipid Nutrition business acquired last year contributed to a record quarter for our Specialty Products business. We look forward to further synergies with our historic business.

“We have an opportunity to build on our solid start and deliver significant earnings growth in 2012 as we continue to pursue long term initiatives that deliver value for our shareholders”, said F. Quinn Stepan, Jr., President and Chief Executive Officer.

The full effect of the deferred compensation plan on quarterly net income was $1.3 million of expense versus $0.5 million of income last year. The accounting for the deferred compensation plan results in operating income when the price of Stepan Company common stock or mutual funds held in the plan fall and expense when they rise. The Company also recognizes the change in value of mutual funds as investment income or loss. The quarter end market prices of Stepan Company common stock are as follows:

The deferred compensation income statement impact is summarized below:

The Company believes that certain non-GAAP measures, when presented in conjunction with comparable GAAP (Generally Accepted Accounting Principles) measures, are useful because that information is an appropriate measure for evaluating the Company’s operating performance. Internally, the Company uses this non-GAAP information as an indicator of business performance, and evaluates management’s effectiveness with specific reference to these indicators. These measures should be considered in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

The Company’s foreign subsidiaries transact business and report financial results in their respective local currencies. As a result, foreign subsidiary income statements are translated into U.S. dollars at average foreign exchange rates appropriate for the reporting period. Because foreign exchange rates fluctuate against the U.S. dollar over time, foreign currency translation affects period-to-period comparisons of financial statement items (i.e. because foreign exchange rates fluctuate, similar period-to-period local currency results for a foreign subsidiary may translate into different U.S. dollar results). For the quarter ending March 31, 2012, the U.S. dollar strengthened against most of the foreign currencies in the locations where the Company does business, when compared to the exchange rates for the quarter ending March 31, 2011. Consequently, reported net sales, expense and income amounts for the quarter ending March 31, 2012, were lower than they would have been had the foreign currency exchange rates remained constant with the rates for the same periods of 2011. Below is a table that presents the impact that foreign currency translation had on the changes in consolidated net sales and various income line items for the first quarter:
