Exhibit 99.1

NORTHFIELD, Illinois, July 22, 2015 -- Stepan Company (NYSE: SCL) today reported:

Stepan Reports Higher Second Quarter and First Half Results

and Announces Dividend

Second Quarter Highlights

First Half Highlights

“Our second quarter operating results benefited from earnings momentum in Surfactants and Polymers, partially offset by a decline in Specialty Products,“ said F. Quinn Stepan, Jr., President and Chief Executive Officer. “Actions taken in 2014 to improve product mix, reduce costs, and improve efficiency contributed to income growth despite the negative impacts of a strong U.S. dollar.”  

“While we are pleased with our year over year improvement during the first half, our focus remains on delivering meaningful growth during the remainder of this year and beyond.  During the quarter, we made significant progress on a number of key strategic initiatives. Our long-term supply agreement with The Sun Products Corporation,

announced on July 9, 2015, will significantly improve our North American capacity utilization.  The purchase of a sulfonation plant in Bahia, Brazil provides us with additional capacity to serve the growing consumer and functional markets throughout Brazil.  We expect continued earnings growth from Polymers, new investments in Latin America and improved operations globally.”

Financial Summary

Summary of Second Quarter Adjusted Net Income Items

Adjusted net income excludes non-operational deferred compensation income and/or expense as well as certain other significant and infrequent or non-recurring items.

Percentage Change in Net Sales

The decrease in quarterly net sales was primarily due to the negative impact of foreign currency translations resulting from the strengthening U.S. dollar and lower selling prices attributable to lower raw material costs.  These decreases were partially offset by volume growth in both the Surfactant and Polymer segments.

Segment Results

Segment Net Sales

Segment Operating Income

Total segment operating income increased $8.0 million or 19% versus the prior year quarter.  Total segment operating income is up $25.6 million or 34% year to date.

Corporate Expenses

Income Taxes

The effective tax rate was 30% for the first half of 2015 compared to 27% for the first half of 2014.  The increase was driven by changes in the geographical mix of income and an unfavorable non-recurring tax charge related to a foreign income tax audit recorded in the second quarter of 2015.

Selected Balance Sheet Information

The Company’s net debt level decreased $8 million for the quarter while the Net Debt ratio dropped from 26% to 24%.

On July 13, 2015, the Company announced that it had completed a $100 million offering of 3.95% Senior Notes due in 2027.  The debt proceeds will be used to fund typical capital expenditures, pay off existing higher cost debt according to normal payoff schedules, and fund investments that support the Company’s strategic initiatives.

($ in millions)

The Company had capital expenditures of $26 million during the quarter and has spent $54 million for the first half of 2015.  This compares to $19 million and $39 million, respectively, in the prior year.  

Outlook

“After six months, we remain on track to re-establish earnings momentum for the full year,” said F. Quinn Stepan, Jr., President and Chief Executive Officer.  

“In the second half, Surfactant earnings should benefit from new commodity laundry volumes in North and Latin America, continued diversification of our business in Europe as well as contributions from improved operations and our efficiency program.  We expect continued Polymer income growth in 2015 driven by higher polyol volumes used in rigid insulation and metal panels.  Our construction projects to add polyol capacity in China and Poland are progressing and both should start production in 2016.”

Reconciliation of Non-GAAP Net Income and Earnings Per Diluted Share

* All amounts in this Table are presented after-tax

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, neither a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

Deferred Compensation Plan

The full effect of the deferred compensation plan on quarterly pretax income was $6.4 million of expense versus $6.0 million of income in the prior year quarter.  The year to date impact was $7.4 million of expense versus $6.4 million of income in the prior 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:

Table IV

Effects of Foreign Currency Translation

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).  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 three and six month periods ending June 30, 2015:
