FOR IMMEDIATE RELEASE

BENCHMARK ELECTRONICS REPORTS SECOND QUARTER 2018 RESULTS

·          Quarterly revenue of $661 million

·          Quarterly operating margin of 2.2% (2.7% non-GAAP)

·          Quarterly EPS of $0.23 ($0.30 non-GAAP)

SCOTTSDALE, AZ, July 24, 2018 – Benchmark Electronics, Inc. (NYSE: BHE) today announced financial results for the second quarter ended June 30, 2018.

⁽¹⁾ Prior period amounts have been adjusted to reflect the adoption of ASC 606 on a retrospective basis.

⁽²⁾ Includes $40 million ($0.82 per share) for the three months ended March 31, 2018 of foreign withholding taxes and state tax expense related to repatriation of foreign cash to US parent company.

On January 1, 2018, we adopted new accounting guidance, FASB ASC Topic 606 “Revenue from Contracts with Customers” (ASC 606), relating to revenue recognition.  We adopted ASC 606 using the full retrospective transition method.  Accordingly, we have adjusted prior period information to be consistent with ASC 606.  The adoption of ASC 606 did not materially impact our overall financial position.

A reconciliation of GAAP and non-GAAP results is included below.

“On balance, we met our commitments for the second quarter.  Bookings grew to $177 million and were above our target mix; revenue was up 7% year-over-year; and cash cycle days of 69 were at the lower end of our target range.  During the quarter, we navigated through a number of medical transitions and made meaningful progress in addressing program ramp challenges.  While our operating margin profile was lower than expected from higher computing revenue, results were in line with our expectations,” said Paul Tufano, Benchmark’s President and CEO.

“Over the past 90 days, we have completed our ASR program and year-to-date have repurchased $78 million worth of stock, which puts us on track to exceed our $100 million target for the year.  We also refinanced and expanded our credit facilities to a combined total of $650 million, which will be accretive to earnings on an annual basis.”

“Our guidance for the third quarter of 2018 reflects our continuing improvement in operational execution and revenue expansion, but is tempered by softness in the semi-cap market.”

Capital Allocation Highlights

·          Accelerated Share Repurchase (ASR) Program completed on July 18 reducing common shares outstanding by 1.7 million shares.

·          Completed expansion of credit facilities to $650 million from $430 million on July 20.

·          Extended maturity date of credit facilities to July 2023.
