EXHIBIT 99.4 UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS The following unaudited pro forma condensed combined financial statements give effect to the proposed acquisition by Benchmark of all the outstanding capital stock of AVEX and Holdings, the related borrowings under a credit facility (the Facility) and borrowings under a capital markets transaction completed by Benchmark on August 13, 1999 (Notes). The AVEX acquisition is subject to customary conditions including approval from various governmental agencies. The AVEX acquisition will be accounted for under the purchase method of accounting. The assets acquired and liabilities assumed will be recorded at their fair values. The unaudited pro forma condensed combined financial statements are based on the historical financial statements of Benchmark and AVEX and the estimates and assumptions set forth below and in the notes to the unaudited pro forma condensed combined financial statements. The unaudited pro forma condensed balance sheet as of June 30, 1999 is presented as if the AVEX acquisition had occurred on that date. The unaudited pro forma condensed combined statements of operations for the year ended December 31, 1998, and the six month period ended June 30, 1999, assume that the AVEX acquisition occurred at the beginning of the earliest period presented. The unaudited pro forma condensed combined financial statements should be read in conjunction with the historical financial statements of Benchmark and AVEX. The unaudited pro forma condensed combined financial statements do not purport to represent what Benchmark's financial position or results of operations would actually have been if the AVEX acquisition had been consummated on the indicated dates, nor are they necessarily indicative of Benchmark's financial position or results of operations for any future period. The results of operations for the six months ended June 30, 1999, are not necessarily indicative of the results to be expected for the entire year or any other interim period. The pro forma adjustments are based on preliminary assumptions and estimates made by Benchmark management. The information necessary to account for the AVEX acquisition in accordance with generally accepted accounting principles is incomplete at this time. Accordingly, the unaudited pro forma condensed combined financial statements assume that the recorded amounts of AVEX's assets and liabilities approximate their fair values. The actual allocation of the consideration paid for AVEX may differ from that reflected in the unaudited pro forma condensed combined financial statements after a more extensive review of the fair values of the assets acquired and liabilities assumed has been completed. Accordingly, the allocation of the purchase price and the resultant amortization of the excess purchase price, which are based on preliminary estimates, may differ from the final purchase price allocation and amortization periods. THE AVEX ACQUISITION The Stock Purchase Agreement provides that Benchmark will acquire AVEX for a total purchase price of $255 million in cash and one million shares of Benchmark Common Stock. In addition, the final purchase price is subject to an adjustment for working capital changes, of which an estimate is reflected in the pro forma adjustments. Financing for the AVEX acquisition is expected to be provided through the Facility and the Notes. AVEX incurred a net loss of $9.7 million during the first six months of 1999 and $84.2 million during 1998. AVEX has taken a number of actions intended to reduce its fixed and other costs and reverse this trend, including the closure of two facilities in areas having relatively high labor costs and the redeployment of the capital assets used in those facilities to plants in areas having lower labor costs, resulting in improved manufacturing utilization; the rationalization of its sales organization and the elimination of approximately 916 employee and contractor positions; and the redefinition of AVEX's customer strategy to focus on fewer, more strategic accounts, with a reduction in the total number of customers. 1 As a result of some of the foregoing actions, AVEX recorded charges to operations in 1998 totaling $33.4 million, including restructuring charges of $15.7 million and the write down of various assets of $17.7 million. Approximately $7.4 million of the restructuring charge relates to the severance and related cost associated with the elimination of approximately 916 contractor and employee positions. AVEX also closed its San Jose, California manufacturing facility and discontinued a design center. As a result, the restructuring charge also included a $6.0 million write down to fair value of certain equipment and leasehold improvements, $2.0 million related to the write off of certain prepaid assets. The write down of various assets totaling $17.7 million, which included adjustments to inventory, accounts receivable and other assets, is included in cost of sales and selling, general and administrative expenses. In the preparation of the unaudited pro forma condensed combined financial statements, the $7.8 million of charges related to the closing of the San Jose, California facility have been excluded as a pro forma adjustment. These charges relate to a facility not a part of AVEX at the time Benchmark expects to close the AVEX acquisition. The remaining charges of $25.6 million have been included in the Unaudited Pro Forma Condensed Combined Financial Statements. The Unaudited Pro Forma Condensed Combined Financial Statements reflect savings that will be realized from the elimination of certain redundant executive headquarter costs and the termination of intercompany services previously provided by the Seller to AVEX under an intercompany agreement, offset by the costs Benchmark will incur to replace the services provided by Seller. No adjustments have been made to reflect other identified actions that could result in potential cost savings but which cannot be quantified at this time. 2 BENCHMARK ELECTRONICS, INC.

The calculation of excess purchase price to be allocated is based on the following assumptions and calculation (in thousands): Total consideration..................... $ 292,362 Transaction costs....................... 3,100 ---------- Total purchase price.................... 295,462 AVEX net book deficit at June 30, 1999.................................. 73,129 AVEX cash and cash equivalents not acquired.............................. 11,552 AVEX due to parent not assumed.......... (228,818) AVEX notes payable not assumed.......... (29,599) ---------- Excess purchase price to be allocated... $ 121,726 ========== 6 (c) To eliminate the historical costs related to (i) certain redundant executive headquarter costs (ii) the termination of intercompany services previously provided by the Seller to AVEX under an intercompany arrangement that included fees based on the estimated utilization of Seller's resources; (iii) AVEX's domestic defined benefit pension plan, which plan and the obligations thereunder are not being continued by Benchmark; offset by (iv) the costs that Benchmark will incur to replace the Seller's intercompany services arrangement. A summary of such adjustments follows (in thousands): FOR THE PERIOD ENDED -------------------------- DECEMBER 31, JUNE 30, 1998 1999 ------------ -------- Redundant executive headquarter costs......................... $ (455) $ (228) Historical intercompany service fee........................... (4,400) (1,800) Historical cost of pension plan not continued................. (1,100) (791) Benchmark replacement of intercompany services arrangement................... 1,000 500 ------------ -------- Total.................... $ (4,955) $ (2,319) ============ ======== (d) To record amortization of excess purchase price to be allocated over an estimated useful life of 15 years. (e) To eliminate the 1998 write down of certain assets related to AVEX's San Jose, California facility which are not being acquired by Benchmark, as described above. In 1999, to eliminate a reduction to the aforementioned write down included in AVEX's historical financial statements. (f) To reduce interest income related to cash balances utilized in funding a portion of the AVEX acquisition. (g) To eliminate intercompany interest expense with the Seller and interest on AVEX notes payable not assumed under the Stock Purchase Agreement. (h) To record amortization of debt issuance costs over the life of the applicable debt instruments. (i) To record interest expense at 7.75%, 7.75%, 8.25% and 6.0% on the amounts outstanding under the Revolving Credit Facility, Term Loan A, Term Loan B and the Notes, respectively, based on current interest rates. A change in the interest rate of 1/8 of a percent would result in a change in annual interest expense related to the amounts outstanding under the Revolving Credit Facility, Term Loan A, and Term Loan B of approximately $183,000. (j) To record income tax adjustments related to the above pro forma adjustments. (k) To adjust AVEX historical income tax expense or benefit as if AVEX was included in the consolidated federal income tax return of Benchmark. In the historical combined financial statements of AVEX, federal income taxes were provided as if AVEX filed a separate income tax return. (l) The following information reconciles the number of shares used to compute historical and pro forma earnings (loss) per common share (in thousands): FOR THE PERIOD ENDED ---------------------------------------- DECEMBER 31, JUNE 30, 1998 1999 ------------------ ------------------ BASIC DILUTED BASIC DILUTED ------ -------- ------ -------- Benchmark historical................. 11,594 12,098 12,209 13,256 Common shares to be issued in AVEX acquisition........................ 1,000 1,000 1,000 1,000 Elimination of Benchmark stock options -- antidilutive on a pro forma basis in 1998....... -- (504) -- -- ------ -------- ------ -------- 12,594 12,594 13,209 14,256 ====== ======== ====== ======== For both 1998 and 1999, the effect of the if-converted method for the Notes is antidilutive and 2.5 million of potential common shares have not been considered in computing diluted earnings per common share. 7
