INDEPENDENT AUDITOR’S REPORT

Participants and Trustees
Ingram Micro 401(k) Investment Savings Plan

We have audited the accompanying statements of net assets available for plan benefits and the related statements of changes in net assets available for plan benefits of the Ingram Micro 401(k) Investment Savings Plan (the Plan), as of and for the years ended December 31, 2003 and 2002. These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan and the changes in net assets available for plan benefits as of and for the years ended December 31, 2003 and 2002, in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets held for investment purposes is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements for the year ended December 31, 2003, and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

NOTE 1 — DESCRIPTION OF PLAN

The following description of the Ingram Micro 401(k) Investment Savings Plan (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

General - The Plan is a defined contribution plan covering substantially all of the United States employees of Ingram Micro Inc., (the Company) who have completed three months of eligibility service. The Plan is designed to comply with Section 401(a) of the Internal Revenue Code as a defined contribution plan and its incorporated Trust is intended to qualify as a tax-exempt trust under Section 501(a) of the Internal Revenue Code. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974. The Plan is administered by the Company and advised by the Benefits Administrative Committee appointed by the Company’s Board of Directors. The assets of the Plan are held and invested by Putnam Fiduciary Trust Company (Putnam), acting as trustee, custodian and recordkeeper.

Contributions - Contributions are made to the Plan by means of a salary deferral agreement under which the participant is entitled to defer pre-tax and after-tax compensation up to the lesser of 15 percent of their eligible compensation or a fixed amount determined annually by the Internal Revenue Service. The Company matches from 50 percent to 100 percent of participant contributions up to the first 5% of eligible compensation depending upon the years of service. The Benefits Administrative Committee may change the Company’s matching contribution in future years. For the years ended December 31, 2003 and 2002, the Company made matching contributions of $3,978,487 and $4,636,355, respectively.

Participant Accounts - Each participant account is credited with the participant’s contribution and an allocation of (a) the Company’s matching contribution and (b) Plan net earnings which include an allocation of certain administrative expenses. Allocations of matching contributions are based on participant contributions, as defined. Allocations of Plan earnings and administrative expenses, when applicable, are based on participant account balances. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested interest in their account balance. Benefit payments allocated to accounts of participants who have elected to withdraw from the Plan, but have not yet been paid amounted to $95,378 at December 31, 2003, and $242,648 at December 31, 2002.

NOTE 1 — DESCRIPTION OF PLAN (Continued)

Participant Loans - Participants may borrow 50 percent of their vested account balance up to $50,000 at prime plus 1 percent with payment of principal and interest made through payroll deductions. A general loan will have a term of five years or less, and up to 15 years will be allowed for a home loan. The loans are secured by the balance in the participant’s account. Participant loans are stated at the unpaid principal value, which are estimated to approximate fair value.

Eligibility - Employees other than those that are employed under a collective bargaining agreement, leased, expatriate employees covered by a nonqualified plan provided such expatriate employees have no United States income source, or employed on a temporary basis are eligible to enter the Plan following the completion of the third month of employment with the Company.

Vesting - Participants are vested on their contributions plus earnings, immediately. Vesting in the Company’s matching contribution is based on years of service. A year of vesting service is defined as any period in which a participant completes 365 days of service. The following schedule describes the vesting percentages for participants.

Payment of Benefits - Upon termination of service before the normal retirement age of 65, a participant with benefits of over $5,000 may elect to defer distribution until normal retirement age or receive a lump sum payment equal to the vested share of the participant’s account.

Upon termination of service at the normal retirement age of 65, a participant may elect to receive a lump sum payment equal to the vested value of his or her account. Benefits may also be accessed in the event of disability or death.

NOTE 1 — DESCRIPTION OF PLAN (Continued)

Payment of Benefits (Continued) - The Plan allows participants to make early withdrawals for certain financial hardships. The Plan also allows in-service withdrawals by participants after they reach age 59-1/2. Participants’ age 59-1/2 taking in-service withdrawals will be required to pay all applicable taxes on the withdrawals but will not be subject to penalty taxes for early withdrawals.

Forfeitures - Forfeitures of unvested Plan assets are used to reduce the Company’s contributions and costs of administering the Plan. Total forfeitures that will be used to reduce future employer contributions at December 31, 2003 are $153,997. Employer contributions were reduced by forfeited nonvested accounts totaling $140,970 and $216,322 for the years ended December 31, 2003 and 2002, respectively.

NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting - The financial statements of the Plan are prepared under the accrual basis of accounting. Administrative and other expenses are recorded as incurred. Benefits are reported when paid.

Basis of Presentation - The financial statements have been prepared in compliance with the Department of Labor Rules and Regulations for reporting and disclosure under ERISA.

Use of Estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of net assets available for benefits at the date of the financial statements and the reported amounts of additions to net assets and deductions from net assets during the reporting period. Actual results could differ from those estimates.

Valuation of Investments - Investments are included in the accompanying financial statements at fair value as determined by quoted market prices. Interest is recorded on the accrual basis and is included in the investment’s value. Purchases and sales of securities are recorded on a trade date basis. Dividends are on the ex-dividend date.

NOTE 4 — EMPLOYER STOCK

Participants may not invest more than 50 percent of their contributions into the Ingram Micro Stock Fund and are not permitted to transfer funds from the Plan’s other investment options into the Ingram Micro Stock Fund. Participants may, however, transfer funds out of the Ingram Micro Stock Fund into any of the Plan’s other funds. At December 31, 2003 and 2002, investments in Ingram Micro stock comprised approximately 9 percent of total net assets available for benefits.

NOTE 5 — PARTY-IN-INTEREST

Certain Plan investments are managed by Putnam. Putnam is the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. Fees paid by the Plan for the investment management services amounted to $23,357 and $25,593 for the years ended December 31, 2003 and 2002, respectively.

NOTE 6 — PLAN TERMINATION

Although the Company has not expressed any intent to do so, it has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, the net assets of the Plan will be allocated as prescribed by ERISA and its related regulations, so that each participant receives 100 percent of his or her account balance as of the date of the termination.

NOTE 7 — TAX STATUS

The trust established under the Plan to hold the Plan’s assets is designed to qualify pursuant to Section 501(a) of the Internal Revenue Code, and, accordingly, the trust’s net investment income is exempt from income taxes. The Plan has received a favorable determination letter of its tax-exempt status from the Internal Revenue Service by a letter dated November 12, 1998. Although the Plan has been amended since receiving the determination letter, the Plan Administrator and the Plan’s tax counsel believe that the Plan is designed and is currently being operated in compliance with the applicable requirements of the Internal Revenue Code.
