5 REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS To the Administrative Committee of the Integrated Electrical Services, Inc. 401(k) Retirement Savings Plan: We have audited the accompanying statements of net assets available for benefits of the Integrated Electrical Services, Inc. 401(k) Retirement Savings Plan (the Plan) as of December 31, 2000 and 1999, and the related statement of changes in net assets available for benefits for the year ended December 31, 2000. These financial statements and the supplemental schedules referred to below are the responsibility of the Administrative Committee. Our responsibility is to express an opinion on these financial statements and supplemental schedules based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States. 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 the Administrative Committee, 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 as of December 31, 2000 and 1999, and the changes in net assets available for benefits for the year ended December 31, 2000, in conformity with accounting principles generally accepted in the United States. Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedules of assets (held at end of year) as of December 31, 2000, and nonexempt transactions for the year ended December 31, 2000, are presented for purposes of additional analysis and are not a required part of the basic financial statements but are 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. The supplemental schedules have been subjected to the auditing procedures applied in the audits of the basic financial statements and, in our opinion, are fairly stated in all material respects in relation to the basic financial statements taken as a whole.

8 INTEGRATED ELECTRICAL SERVICES, INC. 401(K) RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS 1. DESCRIPTION OF THE PLAN: The following description of the Integrated Electrical Services, Inc. 401(k) Retirement Savings Plan (the Plan) is provided for general information purposes only. Participants should refer to the Plan document for more complete information about the Plan's provisions. General The Plan is a defined contribution plan established by Integrated Electrical Services, Inc. (the Company), on January 1, 1999. The Plan was established under the provisions of Section 401(a) of the Internal Revenue Code of 1986, as amended (the Code), which includes a qualified deferred arrangement as described in Section 401(k) of the Code, for the benefit of eligible employees of the Company. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974, as amended (ERISA). The Company, as Plan administrator, established an administrative committee (the Administrative Committee). The Administrative Committee is responsible for the general administration of the Plan. The Administrative Committee is given all powers necessary to enable it to carry out its duties including, but not limited to, the power to interpret the Plan. Trustee American Industries Trust Company (the Trustee), a subsidiary of Hand Benefits & Trust, Inc., is the trustee of the Plan. Trustee fees and administrative costs, excluding participant loan fees, incurred during 2000 were paid either by the Plan or through unallocated forfeitures within the Plan unless the Company elected to pay such expenses on behalf of the Plan. Participant loan fees were paid by the participants requesting the loan. Eligibility All employees, excluding members of a collective bargaining unit, nonresident aliens, leased employees and employees of an affiliate of the Company that has not adopted the Plan, are eligible to participate in the Plan on January 1, April 1, July 1 or October 1 immediately following the later of the date on which he or she completes six months of service or attains age 21. Rollovers Participants may contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. -5-

9 INTEGRATED ELECTRICAL SERVICES, INC. 401(K) RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (Continued) Contributions Eligible employees may contribute, on a pretax basis, an amount up to 20 percent of their compensation, as defined. The Company will make matching contributions based on a percentage, if any, as determined each Plan year by the Company. During 2000, the Company made matching contributions equal to 25 percent of the first 6 percent of each participant's contribution. The Plan allows the Company to make a "true-up" matching contribution at its sole discretion at the end of a Plan year for eligible participants in an amount which, when aggregated with the Company contributions made during the year, will produce aggregate matching contributions equal to the percentage established by the Company. Participant Accounts Each participant's account is credited with the participant's contributions, the Company's matching contributions and the participant's share of earnings, losses and any appreciation or depreciation of the funds invested. The benefit to which a participant is entitled is the benefit that can be provided from the participant's account. Loans Participants may borrow from their before-tax contribution accounts a minimum of $1,000 to a maximum equal to the lesser of (a) $50,000 minus any outstanding loan balance(s) in the last 12 months or (b) 50 percent of their vested account balances. No more than one loan is allowed per account at any given time. Interest rates are established by the Administrative Committee. Loans must be repaid within five years. Principal and interest are repaid through after-tax payroll deductions. Investment Options The Plan allows for participant transactions on any January 1, April 1, July 1 and October 1 with respect to (a) the transfer of funds from one investment alternative to another, (b) changes in the contribution level and (c) changes in the investment of new contributions. Participants may cease their deferrals at the beginning of any payroll period with proper notice. The Plan provides for contributions to be invested by the Trustee among the Company's common stock, five mutual funds and five common/collective trust funds in accordance with participant investment elections and the provisions of the trust agreement. The Trustee utilizes a short-term investment account to invest assets of the Plan pending investment into the directed funds. Vesting Participants are 100 percent vested in their contributions, rollover contributions and earnings thereon. Participants vest in their Company matching contributions, and earnings thereon, as follows: Vested Completed Years of Service Percentage -------------------------- ---------- Less than 3 0% 3 or more 100 -6-

10 INTEGRATED ELECTRICAL SERVICES, INC. 401(K) RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (Continued) Forfeitures Forfeitures result from termination of employment before full vesting has occurred. Forfeitures are first used to pay the Plan's ordinary and necessary administrative expenses. Remaining forfeitures are used to reduce the Company matching contributions. Withdrawals Once age 59-1/2 is attained, a participant may withdraw some or all of the vested amounts in his or her account. If the participant is younger than 59-1/2, he or she may withdraw some or all of the vested amounts in his or her account, excluding earnings thereon, only in the event of financial hardship. Upon retirement, termination of employment, death or permanent disability, participants or their beneficiaries may choose among monthly installments, a life annuity, a joint and 50 percent or 100 percent survivor annuity, a life annuity with a guaranteed payment period of five, 10, 15 or 20 years or a lump sum equal to the vested value of their accounts. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Basis of Accounting The Trustee provides statements, prepared on a cash basis of accounting, to the Company. Adjustments have been made to convert the statements to an accrual basis for reporting purposes. Withdrawals are recorded when paid. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to use estimates and assumptions that affect the accompanying financial statements and disclosures. Actual results could differ from those estimates. Investment Valuation and Gains (Losses) on Investments Investments are reported at market value. Mutual funds and the Company's common stock are valued based upon quoted market prices. The common/collective trust funds are valued at fair value based upon the market value of the underlying assets. The American Industries Composite Employee Benefit Trust - Short-Term Income Fund (the Short-Term Income Fund) is a fully benefit-responsive common/collective trust fund investing in short-term debt instruments, including guaranteed investment contracts. The investments of the Short-Term Income Fund are stated at amortized cost which approximates fair value. Participant loans are valued at cost, which approximates fair value. Realized gains (losses) on the sale of investments and unrealized appreciation (depreciation) in the market value of investments are shown as net appreciation (depreciation) in market value of investments in the statement of changes in net assets available for benefits. Purchase and sales of securities are recorded on a trade-date basis. Dividends are recorded on the ex-dividend date. -7-

INVESTMENTS: The following table presents investments that represent 5 percent or more of the Plan's net assets for December 31, 2000 and 1999: 2000- American Growth Fund of America $ 18,504,237 American Industries Composite Employee Benefit Trust- Benefit Trust Equity Index 500 Fund 11,881,014 Short-Term Income Fund 7,735,998 SMART Aggressive Fund 4,827,056 SMART Moderate Fund 5,444,258 Investment Company of America 5,258,071 Janus Worldwide Fund 14,296,146 MFS Capital Opportunities Fund 11,306,399 1999- American Growth Fund of America 9,939,496 American Industries Composite Employee Benefit Trust- Benefit Trust Equity Index 500 Fund 9,172,467 Short-Term Income Fund 4,896,189 SMART Aggressive Fund 3,214,384 SMART Moderate Fund 3,781,500 Fidelity Advisor Equity Income Fund 3,446,056 Janus Worldwide Fund 9,207,173 MFS Capital Opportunities Fund 6,554,785 During 2000, the Plan's investments (including gains and losses on investments bought and sold, as well as held during the year) depreciated in value as follows: Common/collective trust funds $ (1,100,885) Mutual funds (8,662,194) Common stock (868,759) -------------- $ (10,631,838) 4. TRANSFERS FROM OTHER PLANS: During 2000, account balances of employees of various acquired companies who had participated in plans sponsored by the acquired companies were transferred to the Plan. Transfers from the acquired companies' plans totaled $21,613,046. 5. RISKS AND UNCERTANTIES: The Plan provides for various investments in common/collective funds, mutual funds and the Company's common stock. Investment securities, in general, are exposed to various risks, such as interest rate, credit and overall market volatility risks. Due to the level of risk associated with certain investment securities, it is reasonably possible that changes in the values of investment securities will occur in the near term. -8-

12 INTEGRATED ELECTRICAL SERVICES, INC. 401(K) RETIREMENT SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS (Continued) 6. TAX STATUS: The Plan has not received a determination from the Internal Revenue Service stating that the Plan is designed in accordance with the applicable sections of the Code. However, the Administrative Committee believes that the Plan is currently designed and being operated in compliance with the applicable requirements of the Code and that the Plan was qualified and the related trust was tax-exempt as of December 31, 2000 and 1999. 7. PRIORITIES UPON TERMINATION: Under the terms of the Plan, the Company has the right at any time to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants would become fully vested in the balance of their accounts. The Trustee would then commence distribution as directed by the Administrative Committee. 8. RELATED-PARTY TRANSACTIONS: Certain Plan investments are units of common/collective trust funds managed and distributed by American Industries Trust Company. American Industries Trust Company is the Trustee for the Plan; therefore, these transactions qualify as party-in-interest transactions. In addition, the Plan provides for investment in Company common stock and participant loans, which also qualify as party-in-interest transactions. 9. NONEXEMPT TRANSACTIONS: As reported on Schedule II, certain Plan contributions were not remitted to the trust within the time frame specified by the Department of Labor's Regulation 29 CFR 2510.3-102, thus constituting nonexempt transactions between the Plan and the Company for the year ended December 31, 2000. -9-
