FOR IMMEDIATE RELEASE

BENCHMARK ELECTRONICS REPORTS RECORD SALES
AND RECORD EARNINGS FOR FOURTH QUARTER 2004

ANGLETON, TX, FEBRUARY 8, 2005 – Benchmark Electronics, Inc., (NYSE: BHE) a leading contract manufacturing provider, announced sales revenue of $524 million for the quarter ended December 31, 2004, compared to $487 million for the same quarter last year.  Fourth quarter net income was $20.2 million, or $0.47 per diluted share. In the comparable period last year, net income was $13.4 million, or $0.32 per diluted share. In the fourth quarter of 2003, excluding a special item of $2.8 million ($1.9 million net of tax) in restructuring charges, the Company had net income before special items of $15.3 million, or $0.36 cents per diluted share.

Sales revenue for the year ended December 31, 2004 was $2.0 billion, an 8.8% increase from $1.8 billion of revenue in the previous year.  Net income for the year ended December 31, 2004 was $71.0 million, compared to $55.4 million for the prior year.  Diluted earnings per share was $1.67 for the year ended December 31, 2004, compared to $1.39 per share in the prior year. For the year ended December 31, 2003, excluding two special items, an $8.1 million ($5.4 million net of tax) contract settlement gain and $2.8 million ($1.9 million net of tax) in restructuring charges, the Company had net income before special items of $51.9 million, or $1.31 per diluted share.

“2004 was another good year for Benchmark,” commented Cary T. Fu, President and CEO of Benchmark Electronics, Inc.  “We again exceeded every major goal that we set last February.  We enhanced our customer base, reduced customer concentration, expanded our low cost manufacturing capacities, realigned our resources, increased our technical capabilities and delivered solid financial performance.  Additionally, our 2004 new program bookings provide good momentum for a strong 2005.”

Fourth Quarter 2004 Financial Highlights

•Operating margin for the fourth quarter was 4.6%.

•Return on invested capital of 14.0%.

•Cash balance at December 31, 2004 of $367 million.

•No debt outstanding as of December 31, 2004.

•Accounts receivable were $251 million at December 31, 2004; calculated days sales outstanding were 43 days.

•Inventories decreased by $33 million to $257 million; inventory turns were 7.5 times.

•During the fourth quarter our tax rate was reduced by approximately 2% on a full year basis.  This favorable result was primarily related to the dissolution of an inactive foreign owned subsidiary.

First Quarter and Full Year 2005 Guidance

•Revenue in the first quarter of 2005 is expected to be between $510 million and $530 million.

•Earnings per share for the first quarter of 2005 are expected to be $0.40 to $0.44 per diluted share.

•For the 2005 fiscal year the Company anticipates revenue and earnings growth in the range of 10 – 15%.

Non-GAAP Financial Measures

This press release includes financial measures for earnings and earnings per share for 2003 that exclude certain items and therefore are not in accordance with generally accepted accounting principles (GAAP). A detailed reconciliation between the GAAP results and results excluding special items (non-GAAP) is included at the end of this press release. By disclosing this non-GAAP information, management intends to provide investors with additional information to further analyze the company’s performance and underlying trends.  Benchmark’s results for the fourth quarter of 2003 include the impact of closing our Scotland facility during the fourth quarter of 2003.  In addition, our results for the year ended December 31, 2003 also include the impact of a non-cash gain related to the settlement and release of various claims arising out of customer manufacturing agreements. We are providing information in this earnings release which adds back the one-time costs associated with the closing of our Scotland facility to net income and subtracts the one-time non-cash gain from net income. This allows investors to more readily compare the 2003 fourth-quarter and year-end results with the earnings in accordance with generally accepted accounting principles (GAAP) reported in 2004.

Non-GAAP information is not necessarily comparable to other companies. Non-GAAP information should not be viewed as a substitute for, or superior to, net income or other data prepared in accordance with GAAP as measures of our profitability or liquidity. Users of this

financial information should consider the types of events and transactions for which adjustments have been made.
