November 6, 2026

The Board of Trustees

Harris Associates Investment Trust

111 S. Wacker Drive, Suite 4600

Chicago, IL 60606

Ladies and Gentlemen:

This letter agreement is entered into between Harris Associates L.P. (the “Adviser”), and Harris Associates Investment Trust (the “Trust”) on behalf of Oakmark Bond Fund, a series of the Trust (the “Fund”). In the interest of limiting the expenses of the following class of the Fund referred to below (the “Fund Class”), we agree as follows:

Commencing November 6, 2026, the Adviser agrees through January 27, 2028 to reimburse the Fund Class to the extent, but only to the extent, that the annualized expenses of the Fund Class (excluding taxes, interest, all commissions and other normal charges incident to the purchase and sale of portfolio securities, and extraordinary charges such as litigation costs, but including fees paid to the Adviser), as a percentage of the average net assets of the Fund Class (the “Expense Ratio”), exceed the percentage set forth opposite the Fund Class below (each an “Expense Cap”):

Fund

ETF Share

Class

Oakmark Bond Fund

0.31

The amount of the expense reimbursement by the Adviser to the Fund Class (or any recoupment by the Fund Class to the Adviser) shall be computed on an annual, fiscal year basis, but accrued and paid monthly.

The Trust agrees that the Adviser shall be entitled to recoup from assets attributable to the Fund Class amounts reimbursed to the Fund Class, except to the extent that the Fund Class already has paid such recoupment to the Adviser or such recoupment would cause the Expense Ratio of the Fund Class for that fiscal year to exceed the Fund Class’ Expense Cap or to exceed any lower limit in effect at the time of recoupment. Any such repayment must be made within three years after the year in which the reimbursement occurred.

This letter agreement shall remain in effect until January 27, 2028. During the period covered by this letter agreement, the Expense Cap set forth herein for the Fund Class may only be modified by mutual agreement of the parties that, with respect to the Trust, includes a majority vote of the “non-interested” Trustees of the Trust. This letter agreement shall be binding upon any successors and assigns of the Adviser and supersedes any prior agreement with respect to the subject matter hereof as of November 6, 2026.
