12 BRITT RICE ELECTRIC, INC. AND BRITT RICE COMPANY NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 1998 1. Summary of Significant Accounting Policies The following is a summary of certain significant accounting policies followed in the preparation of these financial statements. The policies conform to generally accepted accounting principles and have been consistently applied. Basis for Recording Income Profits on long term contracts are recorded on the basis of the company's estimates of the percentage of completion of individual contracts, commencing when progress reaches a point where experience is sufficient to estimate final results with reasonable accuracy. That portion of the total contract price is accrued which is allocable, on the basis of the company's estimates of the percentage of completion, to contract expenditures incurred and work performed. As these long term contracts extend over one or more years revisions in cost and profit estimates during the course of the work are reflected in the accounting period in which the facts which require the revision become known. Profits on short term contracts are recorded on the substantial completion of each contract. At the time a loss on a contract becomes known, the entire amount of the estimated ultimate loss on both short term and long term contract is recorded. Property and Equipment Property and equipment is recorded at cost and depreciated over their estimated useful lives using the accelerated methods of depreciation for both financial reporting purposes and for federal income tax purposes. Upon sale or retirement, the cost and related accumulated depreciation are eliminated from the respective accounts and the resulting gain or loss is included in current income. Repairs and maintenance charges which do not increase the useful lives of the assets are charged to income as incurred. 2. Notes Payable The following is a summary of note payable at December 31, 1998:

Federal Income Tax The stockholders of Britt Rice Electric, Inc. have elected under Section 1372 (a) of the Internal Revenue Code to be taxed as a small business corporation. This election permits the undistributed taxable income of a "small business corporation" to be taxed to the stockholders rather than the corporation. Therefore, Britt Rice Electric Inc. does not owe any federal income tax at December 31, 1998. Britt Rice Company is a proprietorship and Britt Rice includes the income of the company with his other income and expense on his federal income tax return form 1040. The federal income tax for the company has been paid and all additional federal income tax is recorded on Britt Rice's personal financial statement. The following is a reconciliation of income for financial statement and taxable income for the year ended December 31, 1998. FINANCIAL TAX ---------- ---------- Income before federal income tax $2,941,323 $2,941,323 Depreciation -- -- Meals and entertainment - 50% non-deductible 11,342 11,342 ---------- ---------- Taxable Income $2,952,665 $2,952,665 ========== ==========

15 ITEM 7. (B) PRO FORMA FINANCIAL INFORMATION INTEGRATED ELECTRICAL SERVICES, INC. UNAUDITED PRO FORMA FINANCIAL STATEMENTS BASIS OF PRESENTATION The unaudited pro forma balance sheet reflects the acquisition by Integrated Electrical Services, Inc. ("IES"), of BRE as if it had occurred on September 30, 1999. The unaudited pro forma statements of operations for the year ended September 30, 1998, presents the statement of operations data to give effect to the 78 electrical and cabling contracting and maintenance companies and related entities (including the 16 companies acquired concurrent with IES' initial public offering) acquired through September 30, 1999 (the "Previously Closed Acquisitions"), BRE and the related pro forma adjustments as if they had occurred on October 1, 1997. The unaudited pro forma statement of operations for the year ended September 30, 1999, presents the statement of operations data to give effect to the Previously Closed Acquisitions, BRE and the related pro forma adjustments as if they had occurred on October 1, 1998. IES has analyzed the savings that it expects to realize from reductions in salaries, bonuses and certain benefits to the owners. To the extent the owners of the Acquisitions have contractually agreed to changes in salary, bonuses, benefits and lease payments, these changes have been reflected in the unaudited pro forma combined statement of operations. Certain pro forma adjustments are based on preliminary estimates, available information and certain assumptions that Company management deems appropriate and may be revised as additional information becomes available. The pro forma financial data do not purport to represent what IES's combined financial position or results of operations would actually have been if such transactions in fact had occurred on these dates and are not necessarily representative of IES's combined financial position or results of operations for any future period. Since the acquired entities were not under common control or management prior to their acquisitions by IES, historical combined results may not be comparable to, or indicative of, future performance. The unaudited pro forma combined financial statements should be read in conjunction with the historical consolidated financial statements and notes thereto included in the company's Annual Report for the year ended September 30, 1998 filed on Form 10-K. See also "Risk Factors" included elsewhere therein.
