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

On June 29, 2026, Zachary C. Parker notified DLH Holdings Corp. (the “Company”) of his decision to resign as President and Chief Executive Officer of the Company effective June 30, 2026. Mr. Parker will continue to serve on the Company’s board of directors (the “Board”) as a non-employee director and beginning July 1, 2026, will receive compensation for service on the Board in accordance with the Company’s policy for compensation for its non-employee directors.

Further, on June 29, 2026, the Board appointed Kathryn M. JohnBull, the Company’s Chief Financial Officer and Treasurer, to the position of President and Chief Executive Officer of the Company, effective July 1, 2026. The Board also appointed Ms. JohnBull as a director of the Company effective on July 1, 2026. In connection with her appointment as the Company’s President and Chief Executive Officer, Ms. JohnBull’s last day as the Company’s Chief Financial Officer and Treasurer was June 30, 2026.

In connection with Ms. JohnBull’s transition into her new role, the Company also announced the appointment of Steven V. Oroho, Jr. as Chief Financial Officer and Treasurer of the Company, effective July 1, 2026. Prior to his appointment as Chief Financial Officer, Mr. Oroho served as the Company’s Senior Vice President, Finance and Accounting.

The Company expects to enter into a separation agreement with Mr. Parker, the terms of which will be reported as soon as practicable in a subsequent Current Report on Form 8-K. Among other matters, it is anticipated that the separation agreement will provide that the Company will enter into an advisory agreement and a separate consulting agreement with Mr. Parker pursuant to which he will initially provide transition and support services to the Company until the end of its 2026 fiscal year in order to support a smooth and efficient transition to the Company’s new leadership team. In addition, it is expected that under the separate consulting agreement, commencing with the Company’s 2027 fiscal year, Mr. Parker will provide consulting services to the Company’s management team on various operational and strategic matters, including business development initiatives, and other assignments as requested by the Chairman of the Board or the chief executive officer.

Summary of JohnBull Employment Agreement

In connection with her appointment as the Company’s President and Chief Executive Officer, on June 30, 2026, the Company entered into a new employment agreement with Ms. JohnBull (the “Employment Agreement”). Under the terms of her Employment Agreement, Ms. JohnBull will receive a base salary at the rate of $600,000 per year and an incentive bonus target, which is based upon achievement of Company profitability, revenue, and other operational goals, of 100% of her base salary. In addition, the Company also approved the grant to Ms. JohnBull of restricted stock units with a grant date value of 75% of her initial base salary. Such restricted stock units were granted under the Company's 2025 Equity Incentive Plan, as amended (the "2025 Plan") and will vest on the third anniversary of the grant date, provided she continues to serve as an employee of the Company until such time.

Under this Employment Agreement, in the event of the termination of Ms. JohnBull’s employment by us without “cause” or by her for “good reason”, as such terms are defined in the Employment Agreement, she would be entitled to: (a) a severance payment equal to two times her base salary; (b) continued participation in our health and welfare plans for up to 18 months; (c) a pro rata bonus, and (d) all accrued but unpaid compensation. The new Employment Agreement also provides that in the event of the termination of her employment with the Company in certain circumstances, including a termination by the Company without cause or by her for good reason, each unexpired option presently outstanding and held by her, shall immediately vest and be exercisable in full and the exercise period during which she may exercise all such options shall be extended to the duration of their original term; and that any other equity incentive awards held by her shall be governed by the terms of the applicable award agreements and the 2025 Plan, except that unvested restricted stock units granted under the new Employment Agreement will provide for accelerated vesting in such circumstances. If her Employment Agreement is terminated because of death or disability, Ms. JohnBull or her beneficiary, as the case may be, will be paid her accrued compensation, a pro rata bonus for the year of termination, and in the case of disability, a severance payment of one year of base salary.

Further, under her Employment Agreement, if within 180 days of a “change in control” (as defined in the new Employment Agreement) either Ms. JohnBull’s employment is terminated without cause, or she terminates her employment for good reason, the Company shall pay and/or provide to her substantially the same compensation and benefits as if her termination was without cause or for good reason, including the accelerated vesting of the restricted stock units granted under the Employment Agreement. Such benefits remain subject to limitation to avoid the imposition of the excise tax imposed by Section 4999 of the Internal Revenue Code of 1986, as amended (the “Code”) if such payments would constitute an “excess parachute payment” as defined in Section 280G of the Code. Pursuant to the employment agreement, Ms. JohnBull remains subject to customary confidentiality, non-solicitation of employees and non-competition obligations that survive the termination of such agreement.

The foregoing summary of Ms. JohnBull’s Employment Agreement with the Company does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Employment Agreement, which is filed as Exhibit 10.1 hereto and incorporated into this report by reference.

Summary of Oroho Employment Arrangements

In connection with the Company’s appointment of Mr. Oroho as its Chief Financial Officer and Treasurer, on June 30, 2026, the Company entered into an at-will employment offer letter (the “Employment Letter”) and a Change in Control, Severance and Covenant Agreement (the “Severance Agreement”) with Mr. Oroho, pursuant to which he will serve as the Chief Financial Officer and Treasurer of the Company.

Under the Employment Letter, the Company agreed to pay Mr. Oroho an annual base salary at the rate of $340,000 per year. In addition, he will be eligible to receive an incentive bonus of up to 70% of his annual base salary. In addition, the Company also approved the grant to Mr. Oroho of restricted stock units with a grant date value of $200,000. Such restricted stock units were granted under the 2025 Plan and will vest on the third anniversary of the grant date, provided he continues to serve as an employee of the Company until such time.

Under the Severance Agreement, the Company agreed to provide Mr. Oroho with certain post-termination payments and benefits if his employment is terminated by us without “cause” or by him for “good reason”, as those terms are defined in the Severance Agreement. These termination payments and benefits include the following: (a) a severance payment of 12 months of base salary; (b) continued participation in our health and welfare plans for a period not to exceed 12 months from the termination date; (c) a pro rata bonus; and (d) all compensation accrued but not paid as of the termination date. Further, the Severance Agreement provides that if his employment is terminated in connection with a change in control, subject to the limitation to avoid the imposition of the excise tax imposed under the Internal Revenue Code, he would be eligible to receive a payment of base salary for a period of twelve months in addition to any accrued compensation, a pro rata bonus, and the continuation benefits. The Severance Agreement also provides that in the event of the termination of his employment with the Company other than for cause, any option awards held by him as of the date of such termination, to the extent vested, shall remain exercisable in accordance with the Company’s equity compensation plans and that any other equity incentive awards held by him shall be governed by the terms of the applicable award agreements and the 2025 Plan; except that unvested restricted stock units granted under the Employment Letter will provide for accelerated vesting in such circumstances. In addition, Mr. Oroho is subject to customary confidentiality, non-solicitation, and non-competition obligations that survive the termination of his employment.

The foregoing summaries of Mr. Oroho’s Employment Letter and Severance Agreement with the Company do not purport to be complete and are subject to, and qualified in its entirety by, the full text of such agreements, which are filed as Exhibit 10.2 and Exhibit 10.3 hereto, respectively, and incorporated into this report by reference.
