FOR IMMEDIATE RELEASE

BENCHMARK ELECTRONICS REVISES THIRD

QUARTER 2007 GUIDANCE DUE TO SLOWER THAN ANTICIPATED

PRODUCT AND PROGRAM TRANSITIONS AND SOFTER DEMAND

ANGLETON, TX, OCTOBER 4, 2007 – Benchmark Electronics, Inc. (NYSE: BHE), a leading contract manufacturing provider, revised its guidance for the third quarter of 2007 due to slower than anticipated product and program transitions, as well as softer than projected marketplace demand.

Based on preliminary information, sales for the third quarter of 2007 are expected to be between $670 million and $680 million. During the quarter, we continued to see strong new program bookings and exceeded our anticipated levels of operating cash flows. Our position in the industry continues to be strong despite the current market condition. Diluted earnings per share for the third quarter, including a $6 million tax benefit, are expected to be between $0.29 and $0.35 on a GAAP basis.

Looking forward, we anticipate new bookings and new program ramps to provide measurable sequential growth for the fourth quarter.

These results are preliminary and therefore subject to the Company’s completion of its third quarter closing and review procedures. At this time, the Company is finalizing its financial results for the third quarter of 2007 and will report those results on October 25, 2007. A conference call hosted by Benchmark management will be held on October 25, 2007 at 10:00 am (Central time) to discuss the financial results of the Company and its current outlook. This call will be broadcast via the Internet and may be accessed by logging on to our website at www.bench.com.
