Separation and Transition Agreement dated September 16, 2024 by and between the Company and Ms. Curtis

THIS SEPARATION AND TRANSITION AGREEMENT (the “Agreement”) is made and entered into as of September 16, 2024 by and between Granite Construction Incorporated (the “Company”) and Elizabeth L. Curtis (“Executive”).

WHEREAS, Executive has served as Executive Vice President and Chief Financial Officer of the Company;

WHEREAS, Executive has resigned from such positions, effective as of September 16, 2024 (the “Transition Date”), and will provide certain transition services to the Company through March 31, 2025 (the “Separation Date”), at which time Executive will retire from employment with the Company (the “Separation”); and

WHEREAS, in connection with the Separation, the Company and Executive desire to enter into this Agreement in order to set forth the respective rights and obligations of the parties.

NOW, THEREFORE, in consideration of the mutual promises, covenants and agreements set forth in this Agreement, the sufficiency of which the parties acknowledge, it is agreed as follows:

1.Transition. Effective as of the Transition Date, Executive ceased to serve as Executive Vice President and Chief Financial Officer of the Company and terminated her participation in the Granite Construction Company Executive Retention and Severance Plan III. During the period commencing as of the Transition Date and continuing until the Separation Date (the “Transition Period”), Executive will remain a full-time employee of the Company and serve as Senior Financial Advisor for the Company, which, for the avoidance of doubt, is not an officer position. As Senior Financial Advisor of the Company, Executive will assist the Company with the transition of principal financial officer duties and responsibilities to the new Chief Financial Officer of the Company and will perform such other duties as may reasonably be requested by the Board of Directors or other senior management of the Company from time to time. During the Transition Period, Executive will be subject to the Company’s policies as may be in effect from time to time. Effective as of the Separation Date, Executive’s employment with the Company and her service as Senior Financial Advisor will automatically terminate.

2.Transition Period Compensation.

    During the Transition Period, the Company shall pay to Executive an annual base salary at the rate in effect immediately prior to the Transition Date in accordance with the Company’s normal payroll schedule. In addition, Executive will remain eligible for employee benefits made generally available to executives of the Company.

4.Accrued Obligations. As soon as practicable following the Separation Date, the Company shall (a) pay to Executive any accrued but unpaid salary or wages for services rendered through the Separation Date (including payment for any accrued but unused vacation as of the Separation Date); and (b) provide reimbursement to Executive for any business expenses that she submits to the Company in accordance with its expense reimbursement policy. In addition, Executive shall be entitled to vested

benefits under the applicable employee benefit plans maintained by the Company in accordance with the terms and conditions of such plans.

5.Release of Claims.

(a)In exchange for the separation payments and other benefits described in Section 3, and in consideration of the further agreements and promises set forth herein, Executive agrees unconditionally and forever to release and discharge the Company, including, without limitation, the Company’s current and former officers, directors, members, managers, employees, representatives, attorneys and agents, as well as all of their predecessors, parents, subsidiaries, affiliates, successors in interest and assigns (collectively, the “Releasees”) from any and all claims, actions, causes of action, demands, rights, or damages of any kind or nature which Executive may now have, or ever have, whether known or unknown, including any claims, causes of action or demands of any nature arising out of or in any way relating to Executive’s employment with, or termination from employment with the Company on or before the date Executive signs this Agreement.

(b)This release specifically includes any and all claims relating to or arising from Executive’s employment with the Company, the terms and conditions of that employment, and the termination of that employment relationship, without limitation: any and all claims for fraud; breach of contract; breach of implied covenant of good faith and fair dealing; inducement of breach; interference with contract; wrongful or unlawful discharge or demotion; violation of public policy; assault and battery; invasion of privacy; intentional or negligent infliction of emotional distress; intentional or negligent misrepresentation; conspiracy; failure to pay wages, benefits, vacation pay, severance pay, attorneys’ fees, or other compensation of any sort; wrongful termination; retaliation; wrongful demotion; discrimination or harassment on any basis protected by federal, state or local law including, but not limited to race, color, sex, gender identity, national origin, ancestry, religion, disability, handicap, medical condition, marital status, and sexual orientation; any claim under Title VII of the Civil Rights Act of 1964, the Civil Rights Acts of 1866, 1870 and 1991, the Family and Medical Leave Act, the Age Discrimination in Employment (“ADEA”), the Older Worker Benefit Protection Act, the Americans with Disabilities Act, the Employee Retirement Income Security Act, the Genetic Information Nondiscrimination Act, Section 1981 of Title 42 of the United States Code, the Rehabilitation Act of 1973, the Equal Pay Act, the Worker Adjustment and Retraining Notification Act, the Uniform Services Employment and Reemployment Rights Act, the California Fair Employment and Housing Act, the California Government Code, the California Labor Code, the California Business and Professions Code, the California Military and Veterans Code, the California Family Rights Act, the Unruh Civil Rights Act, the California Victims of Domestic Violence Employment Leave Act, the California Industrial Welfare Commission Wage Orders, the California Equal Pay Act, the California Worker Adjustment and Retraining Notification Act, the California Constitution, the Texas Labor Code, including, without limitation, Chapter 21 of the Texas Labor Code, also referred to as the Texas Commission on Human Rights Act (including, without limitation, the Texas Discriminatory Use of Genetic Information law), the Texas Payday Law, the Texas Minimum Wage Act, the Texas Anti-Retaliation Act, and the Texas Constitution; and all other federal, state, or local statutes, ordinances and laws; violation of any safety and health laws, statutes or regulations; or any other wrongful conduct, based upon events occurring prior to the date of execution of this release (“Released Claims”). The Released Claims, however, shall not include any claims for vested benefits under the applicable employee benefit plans maintained by the Company in accordance with the terms and conditions of such plans, or any claims for indemnification (including advancement of expenses) arising under any written indemnification agreement between the Company and Executive or pursuant to the Company’s bylaws or pursuant to applicable law.

(c)Executive further understands, acknowledges, and agrees to waive Executive’s rights under any other statute or regulation, state or federal, that provides that a general release does not extend to claims that Executive does not know or suspect to exist in Executive’s favor at the time of executing this Agreement and Release, which if known to Executive must have materially affected Executive’s settlement with the Company. Without limiting the foregoing, Executive further acknowledges that Executive is aware of and familiar with the provisions of California Civil Code Section 1542, which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS THAT THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.

Being aware of this section, Executive hereby expressly waives and relinquishes, with respect to all of the Released Claims, all rights and benefits Executive may have under this statute as well as any under other statutes or common law principles of similar effect.

(d)The parties intend this release by Executive to be a full and comprehensive general release waiving and releasing all claims, demands, and causes of action, known or unknown, to the fullest extent permitted by law except as otherwise expressly provided herein. Nothing in this Agreement is intended to nor shall it be interpreted to release any claim which, by law, may not be released. This Agreement is not intended to and does not affect any rights or claims Executive may have arising after the date this Agreement is executed by Executive. Further, this Agreement shall not limit or prohibit either party’s ability to bring a claim to enforce this Agreement nor shall it waive or limit Executive’s right to indemnification (including with respect to any right to receive advancement of expenses and to be held harmless) pursuant to any applicable directors and officers liability insurance coverage, any written indemnification agreement between the Company and Executive or pursuant to the Company’s bylaws or pursuant to applicable law.

6.Additional Representations and Warranties.

(a)Executive represents that Executive has no pending complaints or charges against the Releasees, or any of them, with any state or federal court, or any local, state or federal agency, division, or department based on any event(s) occurring prior to the date Executive signs this Agreement. Executive further represents that Executive will not in the future file, participate in, encourage, instigate or assist in the prosecution of any claim, complaints, charges or in any lawsuit by any party in any state or federal court against the Releasees, or any of them, unless such aid or assistance is ordered by a court or government agency or sought by compulsory legal process, claiming that the Releasees, or any of them, have violated any local, state or federal laws, statutes, ordinances or regulations based upon events occurring prior to the execution of this Agreement. This prohibition applies only in situations where Executive may legally waive the ability to bring or participate in a legal action against her former employer as a matter of law. Nothing in this Agreement shall be construed as prohibiting Executive from making a future claim with the Equal Employment Opportunity Commission or any similar state agency; provided, however, that should Executive pursue such an administrative action against the Releasees, or any of them, to the maximum extent allowed by law, Executive agrees and acknowledges that Executive

will not seek, nor shall Executive be entitled to recover, any monetary damages from any such proceeding.

(b)The Company represents that neither the Company nor any of its parent, subsidiary or affiliated companies has any pending complaints or charges filed by any of them, or on behalf of any of them, against Executive with any state or federal court, or any local, state or federal agency, division, or department based on any act, omission or event(s) occurring prior to the date the Company signs this Agreement.

7.No Admission of Liability. By entering into this Agreement, neither the Company nor Executive suggests or admits to any liability to one another or that they violated any law or any duty or obligation to one another, or that they committed any wrongdoing whatsoever.

8.Review and Revocation Periods. Executive has twenty-one (21) calendar days to review and sign this Agreement and is advised to consult with an attorney of her choice before signing this Agreement, which includes a release of claims under the ADEA. Executive understands that she may use as much of this 21-day period as she wishes prior to signing. Executive may expressly and voluntarily waive any part or all of the 21-day review period by signing and returning this Agreement prior to the expiration of the review period. Executive may revoke her acceptance of this release for seven (7) calendar days after signing this Agreement (the “Revocation Period”). The revocation must be in writing and delivered to the Company in care of its signatory to this Agreement. If Executive does not revoke this Agreement within the Revocation Period by notice to such person, it shall be fully enforceable without any further action by either party. This Agreement does not become effective until the day after the Revocation Period has expired (such date being the “Effective Date”). In addition, Executive shall execute the Separation Certificate attached hereto as Exhibit A no earlier than one day after the Separation Date and no later than 10 days after the Separation Date. The Company agrees to send to the Executive’s personal email address the Separation Certificate for Executive to execute via DocuSign on the day after the Separation Date.

9.Blue Penciling. If, at any time after the date of the execution of this Agreement, any provision of this Agreement shall be held by any court of competent jurisdiction to be illegal, void or unenforceable, such provision shall be of no force and effect. However, the illegality or unenforceability of such provision shall have no effect upon, and shall not impair the enforceability of, any other provision of this Agreement; provided, however, that if the General Release contained in this Agreement is deemed void or unenforceable, Executive agrees to promptly execute a valid general release and waiver in favor of the Releasees.

10.Sole and Exclusive Benefits. This Agreement provides for the sole and exclusive benefits for which Executive is eligible as a result of her separation of service with the Company, except as otherwise required by law, and Executive shall not be eligible for any contractual benefits under any other agreement or arrangement providing for benefits upon a separation from service, including, but not limited to, any payments any severance plan, policy or program of the Company.
