ANNUAL REPORT ON FORM 10-K

December 31, 2023

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

Certain statements in this Annual Report on Form 10-K, other than purely historical information, are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). These statements include statements about Stepan Company’s and its subsidiaries’ (the Company) plans, objectives, strategies, financial performance and outlook, trends, the amount and timing of future cash distributions, prospects or future events and involve known and unknown risks that are difficult to predict. As a result, the Company’s actual financial results, performance, achievements or prospects may differ materially from those expressed or implied by these forward-looking statements. In some cases, forward-looking statements can be identified by the use of words such as “may,” “could,” “expect,” “intend,” “plan,” “seek,” “anticipate,” “believe,” “estimate,” “guidance,” “predict,” “potential,” “continue,” “likely,” “will,” “would,” “should,” “illustrative” and variations of these terms and similar expressions, or the negative of these terms or similar expressions. Such forward-looking statements are necessarily based upon estimates and assumptions that, while considered reasonable by the Company and its management based on their knowledge and understanding of the business and industry, are inherently uncertain. These statements are not guarantees of future performance, and stockholders should not place undue reliance on forward-looking statements. There are a number of risks, uncertainties and other important factors, many of which are beyond the Company’s control, that could cause the Company’s actual results to differ materially from the forward-looking statements contained in this Annual Report on Form 10-K. Such risks, uncertainties and other important factors, include, among others, the risks, uncertainties and factors set forth under “Part I-Item IA. Risk Factors” and “Part II-Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the risks and uncertainties related to the following:

•

accidents, unplanned production shutdowns or disruptions in any of the Company’s manufacturing facilities;

•

reduced demand for Company products due to customer product reformulations or new technologies;

•

the Company’s inability to successfully develop or introduce new products;

•

compliance with environmental, health and safety, product registration and anti-corruption laws;

•

the Company’s ability to make acquisitions of suitable candidates and successfully integrate acquisitions;

•

global competition and the Company’s ability to successfully compete;

•

volatility of raw material, natural gas and electricity costs as well as any disruption in their supply;

•

disruptions in transportation or significant changes in transportation costs;

•

downturns in certain industries and general economic downturns;

•

international business risks, including fluctuations in currency exchange rates, legal restrictions and taxes;

•

unfavorable resolution of litigation against the Company;

•

the Company’s ability to keep and protect its intellectual property rights;

•

potentially adverse tax consequences due to the international scope of the Company’s operations;

•

downgrades to the Company’s credit ratings or disruptions to the Company’s ability to access well-functioning capital markets;

•

conflicts, military actions, terrorist attacks and general instability, particularly in certain energy-producing nations, along with increased security regulations;

•

cost overruns, delays and miscalculations in capacity needs with respect to the Company’s expansion or other capital projects;

•

interruption of, damage to or compromise of the Company’s IT systems and failure to maintain the integrity of customer, colleague or Company data;

•

the Company’s ability to retain its executive management and other key personnel;

•

the Company’s ability to operate within the limitations of debt covenants; and

•

the other factors set forth under “Risk Factors.”

These factors are not necessarily all of the important factors that could cause the Company’s actual financial results, performance, achievements or prospects to differ materially from those expressed in or implied by any of the Company’s forward-looking statements. Other unknown or unpredictable factors could also impact the Company’s results. All forward-looking statements attributable to the Company or persons acting on the Company’s behalf are expressly qualified in their entirety by the cautionary statements set forth above. Forward-looking statements speak only as of the date they are made, and the Company does not undertake or assume any obligation to update publicly any of these forward-looking statements to reflect actual results, new information or future events, changes in assumptions or changes in other factors affecting forward-looking statements, except to the extent required by applicable laws. If the Company updates one or more forward-looking statements, no inference should be drawn that the Company will make additional updates with respect to those or other forward-looking statements.
