AMENDED AND RESTATED FEE WAIVER AGREEMENT

AMENDED AND RESTATED FEE WAIVER AGREEMENT made as of the 16^th day of December, 2025, between Dimensional Investment Group Inc., a Maryland corporation (the “Fund”), on behalf of certain portfolios of the Fund, as listed on Schedule A of this Agreement (each a “Portfolio,” and together, the “Portfolios”), and Dimensional Fund Advisors LP, a Delaware limited partnership (“DFA”) (formerly Dimensional Fund Advisors Inc.), amending and restating certain waiver agreements previously entered into by the Fund and DFA.

WHEREAS, DFA has entered into Management Agreements with the Fund, pursuant to which DFA provides various services to the Portfolios, and for which DFA is compensated based on the average net assets of such Portfolios; and

WHEREAS, the Fund and DFA have determined that it is appropriate and in the best interests of each Portfolio and its shareholders to limit the expenses of the Institutional Class shares of those Portfolios of the Fund listed on Schedule A of this Agreement;

NOW, THEREFORE, the parties hereto agree as follows:

Fee Waiver by DFA. DFA agrees to reduce all or a portion of its management fee for each Portfolio’s Institutional Class shares listed on Schedule A, such fee waiver as detailed on Schedule A of this Agreement, to the extent necessary to limit the annualized expenses of each Portfolio’s Institutional Class shares to the rate reflected in Schedule A of this Agreement (“Annualized Expense Ratio”).

Duty to Reimburse DFA. If, at any time, the annualized expenses of a Portfolio’s Institutional Class shares are less than the Annualized Expense Ratio listed on Schedule A of this Agreement, the Fund, on behalf of a Portfolio’s Institutional Class shares, shall reimburse DFA for any fees previously waived and/or expenses previously assumed to the extent that the amount of such reimbursement does not cause the Annualized Expense Ratio of a Portfolio’s Institutional Class shares to exceed the limit on Schedule A of this Agreement. There shall be no obligation of the Fund, on behalf of a Portfolio, to reimburse DFA for waived fees or expenses that were assumed by DFA more than thirty-six months prior to the date of any such reimbursement.

Assignment. No assignment of this Agreement shall be made by DFA without the prior consent of the Fund.

Duration and Termination. This Agreement shall begin on February 28, 2026, and shall continue in effect until February 28, 2027 for each Portfolio’s Institutional Class shares and shall continue in effect from year to year thereafter, unless and until the Fund or DFA notifies the other party to the Agreement, at least thirty days prior to the end of the one-year period for each Portfolio’s Institutional Class shares, of its intention to terminate the Agreement for the class. This Agreement shall automatically terminate, with respect to a Portfolio’s Institutional Class shares, upon the termination of the Management Agreement between DFA and the Fund, on behalf of such Portfolio’s Institutional Class shares.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first-above written.
