CONFIDENTIAL SEPARATION AGREEMENT AND RELEASE OF CLAIMS

This CONFIDENTIAL SEPARATION AGREEMENT AND RELEASE OF CLAIMS (this “Agreement”) is made, as of the Effective Date (as defined herein), by and between Xxxxx X. Xxxxxxx (“Executive”) and Stepan Company (the “Company”). Executive and the Company are referred to herein individually as a “Party” and collectively as the “Parties.”

WHEREAS, Executive’s employment with the Company will end as provided in this Agreement;

WHEREAS, the Parties desire to enter into this Agreement to memorialize the Parties’ rights and obligations with respect to Executive’s transition out of and separation from the Company.

NOW, THEREFORE, the Parties agree as follows:

1.Separation Date. Executive’s employment with the Company shall end on November 1, 2024 (the “Separation Date”). As of the Separation Date, Executive shall no longer be an employee of (or hold any other positions with) the Company and its affiliates. Executive agrees not to hold Executive out as a partner, member, director, officer or employee of, or as otherwise affiliated with, the Company or any of its affiliates (including on social media) after the Separation Date. Executive agrees to execute such documents promptly as may be requested by the Company to evidence Executive’s separation from employment, including but not limited to a written resignation from the Company’s Board of Directors. Regardless of whether Executive signs this Agreement, Executive will receive a lump sum payment of all then outstanding final compensation earned through the Separation Date in accordance with applicable law, minus applicable federal, state and local tax withholdings, for services performed for the Company through and including the Separation Date. Executive acknowledges and agrees that Executive shall submit any business expenses in accordance with Company policy within fifteen (15) days of the Separation Date, which shall be reimbursed in accordance with Company policy and regular payroll practices. Except as specifically set forth in this Agreement or as required under applicable law, and except as to any vested benefits under the Grandfathered vacation program, Company’s Retirement Plan for Salaried Employees, 401(k) plan, Employee Stock Ownership Plan II, Management Incentive Plan Deferral Program, and Performance Award Deferred Compensation Plan, Executive’s right to, and participation in, all benefit plans of the Company shall terminate as of the Separation Date in accordance with the specific terms of each plan. To the extent Executive has any vested assets under the Company’s 401(k) plan and Employee Stock Ownership Plan II, the status and treatment of any such assets shall be governed by the applicable terms of such plan. To the extent awarded, Executive will be eligible for an allocation of the Company’s 2024 profit sharing pursuant to the terms of the Employee Stock Ownership Plan II. Executive acknowledges and agrees that, with Executive’s execution and effectuation of this Agreement, Executive is waiving for all purposes, any Claim for additional employment-related compensation of any kind except as specifically set forth herein.

2.Severance Pay. Provided that Executive (a) executes and returns this Agreement within twenty-one (21) calendar days after the Separation Date and (b) complies with this Agreement at all times, then Executive shall be entitled to severance pay in the amount of Two Million Eight Hundred Twenty Thousand Dollars ($2,820,000) (the “Severance Payment”), less all required or authorized taxes, withholdings, and deductions. The Company shall pay the Severance Payment in equal installments over an eighteen (18) month period on the Company’s regularly established payroll dates beginning on the second regular payroll date following the Effective Date, except as required by Section 409A as set forth in Paragraph 17 of this Agreement. Additionally, Executive will be offered 9 months of outplacement services through Xxxxxx’x retained vendor Challenger, Gray & Christmas to assist in Executive’s job search process through Challenger’s C-Suite Program (the contact is Xxxx Xxxxxxxxxx of Challenger, Gray & Christmas (000) 000-0000) (collectively, the “Severance Benefits.”).

3.Health Insurance & COBRA. Effective as of the Separation Date, as required by the continuation coverage provisions of Section 4980B of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Executive will be offered the opportunity to elect continuation coverage under the group medical plan(s) of the Company (“COBRA coverage”). Executive will be provided with a COBRA subsidy of the employer portion of Executive’s health, dental and/or vision benefits under COBRA, paid directly to the provider for a period of eighteen (18) months (“COBRA Subsidy”); provided, however, that the Company shall cease paying the COBRA Subsidy if the Executive becomes employed and has access to coverage under the medical plans of his new employer before the end of the eighteen (18) month period. Executive will be responsible for timely applying for COBRA benefits and timely remitting Executive’s portion of such benefits to the provider.

4.Equity Awards. The unvested portions of Executive’s outstanding equity awards under the 2011 Incentive Compensation Plan, as amended, or the 2022 Equity Incentive Compensation Plan that are scheduled to vest on the next occurring anniversary of such awards’ grant dates will vest as of the Effective Date of this Agreement; provided that Executive’s outstanding performance share awards will vest on a pro-rata basis (or in full with respect to the 2022 awards) through and using the next occurring calendar year-end for the pro-rata calculation and payment of any amounts with respect to Executive’s outstanding performance share awards will be made following the completion of the applicable performance period and only to the extent that the applicable performance conditions are met. Consistent with the retirement treatment for eligible participants under the award terms, Executive’s vested options and stock appreciation rights awards will remain outstanding until the respective expiration dates for such awards unless exercised earlier. Except as expressly set forth herein, Executive’s equity awards remain subject to the terms of the award agreements in all respects, including, but not limited to, the specific settlement dates, as applicable, as set forth in each of the award agreements; taking into account the fact that Executive will be considered a “specified employee” for purposes of Section 409A of the Code.

5.Beneficiary of Payments and Benefits Granted by this Agreement. In the event of Executive’s death prior to receipt of all payments and benefits granted under this Agreement, any such payments and benefits not distributed shall be assigned and distributed to Executive’s wife on the same terms.

The Released Parties agree not to sue Executive in connection with any matters set forth in this Paragraph 6 that arose prior to Company’s execution of this Agreement; provided, in connection with such matters Executive acted in good faith and in a manner the Executive reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the Executive’s conduct was unlawful.

14.Confidentiality, Restrictive Covenants, and Defend Trade Secrets Act.

(a)Executive will not use, disclose or divulge, furnish or make accessible to anyone, directly or indirectly, any Protected Information at any time. “Protected Information” means any and all non-public, trade secret, confidential and/or proprietary information of the Company and its affiliates; provided, however, that Protected Information shall not include: (i) information that becomes generally known to the public without violation of this Agreement or any other confidentiality obligation, and (ii) information that is disclosed to Executive by another party who is under no obligation of secrecy and has a bona fide right to disclose the information.

(f)Nothing in this Agreement shall prohibit or restrict Executive or Executive’s attorneys from: (i) making any disclosure of relevant and necessary information or documents in any action, investigation, or proceeding relating to this Agreement, or as required by law or legal process, including with respect to possible violations of law; (ii) participating, cooperating, or testifying in any action, investigation, or proceeding with, or providing information to, any governmental agency or legislative body, any self-regulatory organization, and/or pursuant to the Xxxxxxxx-Xxxxx Act; (iii) accepting any U.S. Securities and Exchange Commission awards; (iv) initiating communications with, or responding to any inquiry from, any regulatory or supervisory authority regarding any good faith concerns about possible violations of law or regulation; or (iv) without prior notice to the Company, providing information (including documents) to governmental authorities or agencies regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities or agencies regarding possible legal violations (for purpose of clarification, Executive is not prohibited from providing information (including documents) voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Securities Exchange Act of 1934, as amended). Pursuant to 18 U.S.C. § 1833(b), Executive will not be held criminally or civilly liable under any Federal or state trade secret law for the disclosure of a trade secret of the Company or its subsidiaries or affiliates that (A) is made (x) in confidence to a Federal, state, or local

8

government official, either directly or indirectly, or to Executive’s attorney and (y) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If Executive files a lawsuit for retaliation by the Company for reporting a suspected violation of law, Executive may disclose the trade secret to Executive’s attorney and use the trade secret information in the court proceeding, if Executive files any document containing the trade secret under seal, and does not disclose the trade secret, except pursuant to court order. Nothing in this Agreement is intended to conflict with 18 U.S.C. § 1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section.

(g)Nothing in this Agreement shall prevent Executive from discussing or disclosing information about unlawful acts in the workplace, such as harassment or discrimination or any other conduct Executive has reason to believe is unlawful.

15.No Admission of Wrongdoing. Executive and Company agree that neither this Agreement, nor the furnishing of the consideration for this Agreement, shall be deemed or construed at any time to be an admission by Executive or any Released Party of any improper or unlawful conduct.

16.Confidentiality of Agreement. Executive agrees that this Agreement is confidential and that confidentiality is mutually beneficial to the Parties. Executive agrees not to disclose any information regarding the terms of this Agreement, except to Executive’s immediate family and any tax, legal or other counsel Executive has consulted regarding the meaning or effect hereof or as required by law, and Executive will instruct each of the foregoing not to disclose the same to anyone. The Company may disclose the terms and conditions of this Agreement and the circumstances of Executive’s separation of employment if required for business purposes, including securities law requirements, and to effectuate this Agreement to its respective officers, employees, board of directors, stockholders, insurers, attorneys, accountants, state and federal tax authorities and those of its affiliates, or as may otherwise be required by law. Nothing in this Section is intended to restrict the Parties’ truthful cooperation with any governmental investigation or inquiry.

17.Section 409A. It is the intention of the Parties that payments or benefits payable under this Agreement comply with or be exempt from Code Section 409A, and not be subject to the additional tax imposed pursuant to Code Section 409A. To the extent such potential payments or benefits could become subject to Section 409A, the Parties shall cooperate to amend this Agreement with the goal of giving Executive the economic benefits described herein in a manner that does not result in such tax being imposed. A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits that constitute “nonqualified deferred compensation” within the meaning of Code Section 409A upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Code Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” For purposes of Code Section 409A, Executive’s right to receive any installment payments pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment under this Agreement specifies a payment period with reference to a number of days

9

(e.g., “payment shall be made within thirty (30) days following the date of termination”), the actual date of payment within the specified period shall be within the sole discretion of the Company. Notwithstanding anything to the contrary in this Agreement, if Executive is deemed on the Separation Date to be a "specified employee" within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered “nonqualified deferred compensation” under Code Section 409A payable on account of a "separation from service," such payment or benefit shall not be made or provided until the date which is the earlier of (A) the expiration of the six (6)-month period measured from the date of such "separation from service" of Executive, and (B) the date of Executive’s death, in each case to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this section (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to Executive in a lump sum, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

18.Tax Consequences. The Company makes no representations or warranties with respect to the tax consequences of the payments provided to Executive or made on Executive’s behalf under the terms of this Agreement. Executive agrees and understands that Executive is responsible for payment, if any, of local, state and/or federal taxes on the payments made hereunder by the Company and any penalties or assessments thereon. Executive further agrees to indemnify and hold the Company harmless from any claims, demands, deficiencies, penalties, interest, assessments, executions, judgments or recoveries by any government agency against the Company for any amounts claimed due on account of: (a) Executive’s failure to pay or the Company’s failure to withhold, or Executive’s delayed payment of, federal or state taxes; or (b) damages sustained by the Company by reason of any such claims, including attorneys’ fees and costs.

19.Savings Clause. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable, this Agreement shall be enforceable as closely as possible to its original intent, which is to provide the Released Parties with a full release of all legally releasable claims through the date upon which Executive signs this Agreement and to provide a release of Executive as provided for herein.

20.Governing Law. This Agreement shall be governed by and construed in accordance with the laws of Illinois, without regard to the application of any choice-of-law rules that would result in the application of another state’s laws.

21.No Jury Trial.

(a)In exchange for good and valuable consideration set forth in this Agreement, and except as expressly set forth below, the parties mutually agree that any dispute, claim or difference arising under or relating to this Agreement; arising under any federal, state, or local statute, regulation, law, ordinance, or the common law (including but not limited to any law prohibiting

10

discrimination); arising in connection with Executive's employment or the termination thereof; and/or involving Executive and any of the Released Parties shall be submitted to a federal or state court located in Cook County, Chicago, Illinois. The parties agree that prior to the service of process, if required, the parties shall negotiate in good faith for a period of thirty (30) days in an effort to resolve any dispute privately, amicably and confidentially. Except to the extent expressly set forth below, the parties understand, agree, and consent to trial by a court of competent jurisdiction and Executive and the Company hereby each expressly waive the right to trial by jury of any claims arising out of this Agreement.

(b)Further, to the fullest extent permitted by law, and except as provided below, Executive understands and agrees that all claims must be brought in Executive’s individual capacity and not as a plaintiff, representative, or class member in any purported class, collective, or representative proceeding and accordingly, there is no right or authority for any dispute to be heard or arbitrated on a collective action basis, on a class action basis, or on bases involving claims or disputes brought in a representative or private attorneys general capacity on behalf of the general public, on behalf of other employees (or any of them) or on behalf of other persons alleged to be similarly situated.

(c)The parties agree that a party may bring an action in court to obtain a temporary restraining order, injunction, or other equitable relief available in response to any violation or threatened violation of the restrictive covenants set forth in herein.

(d)Notwithstanding the “Savings Clause” Section, in the event any provision in this Section is in conflict with a mandatory provision of applicable law, the conflicting provision shall be automatically severed and the remainder of the Agreement construed to incorporate the mandatory provision. In the event of such automatic severance and modification with respect to a particular provision, the remainder of this Agreement shall not be affected and shall be enforced.

22.Each Party the Drafter. This Agreement, and the provisions contained in it, shall not be construed or interpreted for, or against, any party to this Agreement because that party drafted or caused that party’s legal representatives to draft any of its provisions.

23.Assignment; Third-Party Beneficiaries. This Agreement is personal to Executive and may not be assigned by Executive. This Agreement is binding on, and will inure to the benefit of, the Released Parties. The Released Parties are expressly intended to be third-party beneficiaries of the releases set forth in the “Release” Section, and it may be enforced by each of them.
