Exhibit 99.1

Stepan Reports Record Quarterly Earnings

Northfield, Illinois, April 25, 2017 -- Stepan Company (NYSE: SCL) today reported:

First Quarter Highlights

• Reported net income was a record $31.9 million, or $1.37 per diluted share versus $27.9 million, or $1.22 per diluted share, in the prior year.  Adjusted net income* was a record $31.7 million, or $1.36 per diluted share versus $29.7 million, or $1.30 per diluted share, in the prior year.  

• Surfactant operating income was a record $38.2 million versus $37.2 million in the prior year.  This increase was primarily attributable to lower manufacturing costs, mostly resulting from previous actions taken to close plants in Canada and Brazil. Surfactant sales volume was down 7% from the prior year.

• Polymer operating income was $21.4 million versus $22.2 million in the prior year.  This decrease was mostly attributable to higher costs associated with the new production facility in China and higher raw material costs. Polymer sales volume was up 8% versus prior year.

• Specialty Product operating income was $1.3 million versus $2.3 million in the prior year.  This decrease was primarily attributable to order timing differences within our pharmaceutical and flavor business.  

* Adjusted net income is a non-GAAP measure which excludes deferred compensation income/ expense as well as other significant and infrequent/non-recurring items. See Table II for reconciliations of non-GAAP adjusted net income and adjusted earnings per share.

“The Company had a good start to the year and delivered record quarterly results,” said F. Quinn Stepan, Jr., Chairman, President and Chief Executive Officer. “The quarter benefited from structurally lower manufacturing costs, enhanced internal efficiencies and higher Polymer volumes.”

Summary of First Quarter Adjusted Net Income Items

Adjusted net income excludes deferred compensation income/expense, which is a non-operational item, and other significant and infrequent or non-recurring items.

• Deferred Compensation:  The current year quarter includes $0.8 million of after-tax income versus $1.8 million of after-tax expense in the prior year.

• Business Restructuring:  The current year quarter includes $0.6 million of after-tax expense attributable to decommissioning costs related to the Canadian plant closure announced in 2016.

Percentage Change in Net Sales

The 5% increase in quarterly net sales was primarily due to higher selling prices, which were attributable to the pass-through of higher raw material costs.  These higher selling prices were partially offset by a 4% decline in sales volume and the negative impact of foreign currency translation.

Polymers	$	21,399	$	22,197		(4	)%
Specialty Products	$	1,275	$	2,333		(45	)%

Total segment operating income decreased $0.9 million or 1% versus the prior year.  

• Surfactant net sales were $322.6 million, a 4% increase versus prior year.  Selling prices were up 12% primarily due to the pass-through of higher raw material costs.  Sales volume was down 7% mostly due to lower North American and European consumer product and agricultural volumes.  The translation impact of a stronger U.S. dollar decreased net sales by 1%. Surfactant operating income increased $1.0 million versus the prior year, primarily driven by lower manufacturing costs that were mostly attributable to the plant closures in Canada and Brazil.  

• Polymer net sales were $126.6 million in the first quarter, an 11% increase versus prior year.  Sales volume increased 8% in the quarter primarily due to continued growth in polyols used in rigid foam insulation and insulated metal panels.  Increased selling prices partially offset higher raw material costs. Polymer operating income decreased $0.8 million versus the prior year.  This decrease was attributable to higher costs associated with the Company’s new production facility in China and slightly lower unit margins, partially offset by higher global Rigid Polyol sales volume.   

• Specialty Products net sales were $19.1 million, $3.0 million lower than prior year.  Operating income decreased $1.1 million versus the prior year.    The quarterly decline reflects a combination of lower volume and lower margins.  A significant portion of the lower volume is due to the timing of orders in our pharmaceutical and flavor businesses.

Corporate Expenses

	Three Months Ended March 31
($ in thousands)	2017		2016		% Change
Total  -  Corporate Expenses	$	14,852	$	17,168		(13	)%

Business Restructuring Expense	$	786	$	-		-
Adjusted Corporate Expense	$	13,690	$	14,448		(5	)%

* See Table III for a discussion of deferred compensation plan accounting.

• Corporate expenses, excluding deferred compensation and business restructuring expense, decreased $0.8 million, or 5%, for the quarter.  This decrease was mostly attributable to environmental remediation expense recognized in the first quarter of 2016 that did not recur in 2017.  

Income Taxes

The Company’s effective tax rate was 28% for the first quarter of 2017 versus 31% for the first quarter of 2016.  The decrease was primarily attributable to higher excess tax benefits derived from stock based compensation awards exercised or distributed in the first quarter of 2017 versus 2016.  The lower tax rate was also driven by an unfavorable tax settlement related to a foreign income tax audit recorded in the first quarter of 2016 that did not recur in 2017.

Selected Balance Sheet Information

The Company’s net debt level increased $27.6 million versus prior year-end and the net debt ratio increased from 13% to 15%.  The $27.9 million decrase in cash was primarily attributable to higher working capital requirements, which are typical for the Company in the first quarter.

Inventories		189.8			173.7

	$	313.5		$	278.8

Capital spending was $20.4 million versus $19.3 million in the prior year quarter. For the full year, the Company expects capital spending to be between $100 million and $120 million.

Outlook

“After a record first quarter, we remain optimistic about the balance of the year.  We believe that benefits from our enhanced internal efficiencies, continued growth in our core polymer markets and our product and end-market diversification efforts should positively impact 2017.  Conversely, higher raw material costs may pressure margins.  Overall, we believe earnings for the year should grow,” said F. Quinn Stepan, Jr., Chairman, President and Chief Executive Officer.

The Company believes that certain non-GAAP measures, when presented in conjunction with comparable GAAP (Generally Accepted Accounting Principles) measures, are useful for evaluating the Company’s operating performance and provide better clarity on significant non-operational items.  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.

Table III

Deferred Compensation Plan

The full effect of the deferred compensation plan on quarterly pre-tax income was $1.3 million of income versus $2.9 million of expense in the prior year.  The accounting for the deferred compensation plan results in operating income when the prices of Stepan Company common stock or mutual fund shares held in the plan fall and expense when they rise.  The Company also recognizes the change in value of mutual fund shares as investment income or loss.  The quarter end market prices of Stepan Company common stock are as follows:

	2017		2016
	3/31		12/31		9/30		6/30		3/31
Stepan Company	$	78.81	$	81.48	$	72.66	$	59.53	$	55.29

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 month period ending March 31, 2017 as compared to 2016:

($ in millions)	Three Months Ended March 31				Increase (Decrease)			(Decrease) Due to Foreign Currency Translation
