Item 5.02. Departure of Directors or Principal Officers; Election of Directors; Appointment of Principal Officers; Compensatory Arrangements of Certain Officers.

(e) On May 20, 2026, the Compensation Committee of the Board of Directors of Tutor Perini Corporation (the “Company”) unanimously approved the Tutor Perini Corporation Deferred Compensation Plan (the “Plan”). The Plan is intended to be an unfunded arrangement for eligible employees who are part of a select group of management or highly compensated employees of the Company and its subsidiaries within the meaning of ERISA and is intended to comply with the requirements of Section 409A of the Internal Revenue Code of 1986, as amended.

Under the Plan, eligible employees designated by the Company, including the Company’s named executive officers, may participate in the Plan to defer receipt of their cash compensation, including a percentage of their salaries, annual and long-term incentive bonuses, cash-settled restricted stock units and cash-settled performance stock units.

Elective deferrals of cash compensation are credited to a bookkeeping account established in the name of the participant. A participant is always 100% vested in their elective cash deferrals and any earnings thereon. The Company may make discretionary contributions to the Plan for selected participants and may subject such contributions to a vesting schedule.

Participant accounts will be credited with an investment return determined as if each account were invested in various investment alternatives made available by the Plan administrator and elected by the participant. The Company may set aside assets to fund its obligations under the Plan in a limited (“rabbi”) trust, subject to the claims of the Company’s creditors in the event of the Company’s bankruptcy or insolvency.

Participants may elect to receive distributions of their accounts: (i) while still in the service of the Company, in either a lump sum or in two to five annual installments, in each case beginning no earlier than two years after such amounts were earned; (ii) upon a separation from service prior to reaching retirement eligibility (which is age 60 with at least seven years of cumulative service), in a lump sum paid no earlier than six months after separation from service; or (iii) upon a separation from service on or after reaching retirement eligibility, in either a lump sum or in two to 10 annual installments, in each case beginning no earlier than six months after separation from service. In addition, a participant’s account balance will be distributed within 30 days following the participant’s death, without regard to any participant election. A participant may also request a distribution from the Plan due to an unforeseeable emergency, subject to the approval of the Plan administrator.

The foregoing summary of the Plan does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Plan, which will be filed as an exhibit to the Company’s Quarterly Report on Form 10-Q for the quarter ending June 30, 2026, and is incorporated herein by this reference.
