Exhibit 10.3

March 11, 2026

Miles Brittain

Dear Miles:

As we discussed, you have notified NWPX Infrastructure, Inc. (the “Company”) that you wish to retire, and the Company has accepted your resignation from your full-time role of Executive Vice President, effective April 3, 2026. Provided below are details your transition from full-time employment to part-time status, subject to your agreement to certain terms and conditions.

This Confidential Retirement Agreement (the “Agreement”) sets forth an amicable arrangement for the termination of your full-time employment by providing you with Continued Employment, pay and benefits in exchange for, among other things, a release of claims. This Agreement is not an acknowledgement of wrongdoing by you or the Company. If you enter into this Agreement, you agree that you are doing so voluntarily.

1.    End of Full-Time Employment. Your full-time employment with the Company will end on April 3, 2026.

2.    Performance Share Units. In accordance with the terms of the Performance Share Unit Agreement, your shares that vest on March 31, 2026 shall vest on that date. Any shares that are unvested at the time your full-time employment ends will be forfeited, as discussed below.

3.    Return of Company Property. With the exception of your company provided cell phone and laptop computer which will remain in your possession, on your last day of full-time employment or immediately thereafter, you must return any and all Company property in your possession or control, including but not limited to any Company credit cards, keys, card keys, employee badges, documents (including all financial and accounting documents), manuals, customer and product lists and information, equipment, supplies, strategic planning information, and human resources information, as well as any other property belonging to the Company or any Company-owned or affiliated company.

4.    Continued Employment. You will remain a Company employee in a part-time capacity from April 6, 2026 until April 15, 2029 (the “Continued Employment Period”). During that time, your title will be Consultant. In this role, you will be expected to be reasonably available to the Company to provide consulting services, as requested, in areas of your expertise including but not limited to operations, capital project deployment, business analysis, the steel market, metallurgical and quality matters, and the evaluation and analysis of potential merger and acquisition targets. The amount of time needed to perform these services may vary during the Continued Employment Period at the Company’s discretion, but it is expected to be no more than eighty (80) hours per month. The Company expects that most if not all of this work can be performed remotely, though you agree to be available to come into the office as reasonably requested from time to time by the Company during the Continued Employment Period.

5.    Pay and Benefits During Continued Employment Period. The Company shall pay you $175,000 per year, less applicable deductions and withholdings, to be paid in equal installments in accordance with the Company’s regular payroll cycles. You will be eligible for the same benefits, including 401(k) plan participation and health insurance, generally made available to Company employees but you will not be eligible for any incentive compensation programs.

The Continued Employment Period and the pay and benefits provided in this Agreement are in lieu of all other forms of severance or other compensation payments under any Company policy, plan, practice or agreement (excluding vested retirement benefits). They are unique and exclusive to you and are available to you only if you execute and do not revoke this Agreement. They constitute additional benefits and compensation to which you would not otherwise be entitled. By accepting this Agreement, you hereby waive any other benefits and compensation that may be provided under any other agreement or the Company’s (or any of its subsidiaries or affiliates’) policies, plans or practices (excluding vested retirement benefits). You specifically acknowledge that in exchange for the Continued Employment Period and the pay and benefits provided in this Agreement, you waive any rights to receive any Performance Share Units (“PSUs”) - pursuant to the Performance Share Unit Agreements (the “PSU Agreements”) you entered into with the Company as of March 28, 2024 and March 27, 2025 – during the Continued Employment Period. This specific waiver is made pursuant to Section 1.15 of the PSU Agreements.

6.    Treatment of Restricted Stock Units. The Company will honor the original terms of the Restricted Stock Unit (“RSU”) agreements during your Continued Employment Period as follows:

7.    Termination. Employee’s employment and this Agreement may be terminated: (i) by Employer with or without Cause (as defined below); (ii) by Employer due to Employee’s death or Disability (as defined below); or (iii) by Employee.

7.1    Termination by Employer for Cause. Employer shall have the right, at its option, to immediately terminate Employee’s employment and this Agreement for Cause.

(i)“Cause” means any of the following, as reasonably determined by Employer:

a)    any material breach of this Agreement by Employee;

b)    Employee’s refusal or repeated failure to perform, or gross negligence (defined as extreme indifference to or reckless disregard for Employee’s obligations, duties, loyalties, or responsibilities to Employer) in performing, those assigned job responsibilities which are reasonably consistent with the duties of Employee’s position, as directed by the VP/GM, or his designee, including any deliberate or grossly negligent disregard of the written rules or policies of Employer;

c)    Employee’s engagement in any dishonesty, excluding unintentional or minor acts or omissions, with respect to Employer (including without limitation acceptance of any bribes or kickbacks or other acts of self-dealing), fraud, embezzlement, theft, misappropriation of funds or other assets of Employer, or an undisclosed conflict of interest that can reasonably be expected to have a material adverse effect on the affairs of Employer or, in Employer’s discretion, would tend to impugn Employee’s reputation or the reputation of Employer;

d)    Employee’s commission of an intentional act, or intentional failure to act, that is materially detrimental to the reputation, character or standing of Employer, constitutes disloyalty, dishonesty or intentional breach of fiduciary duty to Employer, or that otherwise materially jeopardizes or compromises Employer’s business relationships or performance or, in Employer’s discretion, impugns Employee’s reputation or the reputation of Employer; or

e)    the unauthorized disclosure by Employee of any Confidential Information or trade secret of Employer.

For the avoidance of doubt, unless accompanied by conduct falling under one of the categories set forth in this Section 7.1(i), “Cause” does not include: (1) differences of opinion with respect to strategy or implementation of business plans, (2) the success or lack of success of any such strategy or implementation, or (3) any failure to achieve any performance targets, whether relating to Employee, Employer, or otherwise.

(ii)     Notwithstanding the foregoing, the conduct described in Sections 7.1(i)(a) and (b) shall not constitute Cause unless: (A) Employer has delivered to Employee written notice identifying the conduct deemed to qualify as Cause; and (B) Employee fails to take sufficient remedial action to cure the conduct, as reasonably determined by Employer, within thirty (30) days after delivery of the notice.

7.2    Termination Due to Employee’s Death or Disability. Employee’s employment will automatically terminate upon Employee’s death. Employer’s decision to terminate because of Disability shall be based on its good faith determination that Employee is unable, as a result of physical or mental illness, to perform the essential functions of his position, despite reasonable accommodation, for an aggregate of ninety (90) days during any twelve (12)-month period (“Disability”). Employer’s determination of Disability will consider any reasonable accommodation that Employer may provide without undue hardship and any other considerations required by law. For the avoidance of doubt, a termination due to Employee’s death or Disability shall not be considered a Termination by Employer without Cause for purposes of Severance, as set forth in Section 8.2.

7.3    Termination by Employer Without Cause. Employer may terminate Employee’s employment and this Agreement without Cause by delivering at least thirty (30) days prior written notice stating the Termination Date. During the period between the delivery of the notice of termination and the Termination Date (“Notice Period”), Employee’s employment shall continue, and Employee shall continue to perform his duties and cooperate in the orderly transition of his duties. Employer may, at its option, pay Employee’s then-current Base Salary for the Notice Period and excuse him from any further duties during the Notice Period.

7.4    Resignation by Employee Without Cause. Employee may resign his employment without cause and terminate this Agreement by giving Employer at least thirty (30) days’ prior written notice of the Termination Date. Employer may, at its option, pay Employee’s then-current Base Salary for the Notice Period and excuse him from any further duties during such period.

8.           Payments upon Termination.

8.1    Accrued Salary and Vested Benefits. Regardless of the reason for termination, Employer will pay Employee all earned Base Salary under Section 5 through the Termination Date in a timely manner as required by law, and any unreimbursed business expenses no later than sixty (60) days after the Termination Date, and Employee will also be entitled to receive any vested benefits, consistent with any applicable plan or agreement (“Accrued Salary and Vested Benefits”). Accrued Salary and Vested Benefits shall expressly exclude, and Employee will have no rights to any unvested benefits, unearned Base Salary, or any other compensation or payments after the Termination Date except as stated in this Section 8.

8.2    Severance Pay for Termination by Employer Without Cause.

(i)    Employee shall be eligible for severance pay (“Severance”), contingent upon Employee’s timely execution and non-revocation of a release agreement in a form mutually acceptable to Employer and Employee (“Release”) and substantially similar to the release attached as Exhibit A, if Employer terminates Employee’s employment during the Continued Employment Period without Cause pursuant to Section 7.3. Severance shall be in a gross amount equivalent to the unpaid Base Salary the Employee would have received during the remainder of the Continued Employment Period.

(ii)    If Employee is eligible for Severance, Employer shall pay the Severance as follows, provided that the following preconditions (“Preconditions”) have been met: (a) Employee has executed the Release following the Termination Date (but in no event later than the time period specified in the Release for its execution); and (b) such Release is in full force and effect, taking into account the revocation period applicable to the Release. Employer shall pay the Severance in a lump sum on the payroll immediately following the Employee’s termination. In addition, Company health insurance benefits shall continue without interruption, with the Company paying for the Employee’s COBRA premiums for the remainder of the Continued Employment Period. For the avoidance of doubt, failure by Employee to timely execute the Release in accordance with this Section 8.2 shall result in forfeiture of the Severance.

9.    Release of Claims. In consideration for the Continued Employment Period and the pay and benefits provided in this Agreement, you and your heirs, executors, representatives, agents, insurers, administrators, successors and assigns fully waive, release and discharge the Company, including, without limitation, all of the Company’s related corporations, affiliates, parents, subsidiaries, joint ventures, and current and former directors, officers, employees, agents, attorneys, insurers, shareholders, representatives and assigns (the “Released Parties”), from any and all liability, damages, claims or causes of action, direct or indirect, known or unknown, relating in any way to your employment with the Company or the termination of that employment. You acknowledge and understand that by entering into this Agreement, you are waiving and releasing any legal claims you may have relating to your employment at the Company and the termination of that employment.

This release and the ADEA release in Section 10 do not waive any rights you may have, if any, in vested retirement benefits with the Company or for unemployment compensation benefits with a state agency. The releases also do not prevent you from pursuing a claim that the Company has violated the terms of this Agreement. Your releases also do not prevent you from filing a claim for discrimination, or participating in an investigation, with the Equal Employment Opportunity Commission, the National Labor Relations Board or any applicable state labor agency, but you agree not to accept any monetary damages or other compensation for any claim.

10.    Specific Release of ADEA Claims. In further consideration of the Separation Pay and Separation Benefits provided to you in this Agreement, you hereby irrevocably and unconditionally fully and forever waive, release and discharge the Released Parties from any and all claims, whether known or unknown, from the beginning of time to the date of your execution of this Agreement, arising under the Age Discrimination in Employment Act (“ADEA”), as amended, and its implementing regulations, including the Older Workers’ Benefit Protection Act.

You agree that you will take all steps reasonably necessary to ensure that those parties to whom disclosure is permitted will maintain the confidentiality of this Agreement and that you will be personally liable if they violate the confidentiality of this Agreement. In no manner will this obligation prevent you from responding to any government agency, court order or subpoena with truthful and accurate information.

15.    Confidentiality Obligations. You acknowledge that you have a duty as a former employee of the Company to keep confidential all proprietary or confidential information obtained by you during the course of your employment with the Company. During the course of your employment, you have had access to and have used substantial amounts of Company confidential and proprietary information, including but not limited to proprietary processes and procedures; financial and accounting information; strategic planning information; human resources information; Company policies, procedures and objectives; Company operating information; and customer and supplier information (“Confidential Information”).

You agree to immediately notify the Company in writing upon receipt of such a summons, subpoena or other request for any Confidential Information. You understand that your disclosure of Confidential Information to anyone may subject you and any other user of that information to legal and equitable claims by the Company.

You agree that you will not in any way disparage or harm the name or reputation of the Company, any Company-owned business or any Company affiliate, including any such entities’ past or present officers, directors, employees, agents or attorneys, in either their personal or official capacities. In no manner will this obligation prevent you from responding to any government agency, court order or subpoena with truthful and accurate information. This obligation also does not prevent you from disclosing or discussing conduct that constitutes unlawful discrimination, harassment, retaliation, a wage and hour violation, or sexual assault, or any other conduct that you are entitled to disclose pursuant to applicable federal, state, or local law.
