        This Proxy Statement is being furnished in connection with the solicitation of proxies by the Board of Directors ("the Board") of Benchmark Electronics, Inc. ("the Company") for use at the 2006 Annual Meeting of Shareholders of the Company to be held on Wednesday, May 10, 2006, beginning at 10:00 a.m. (local time), and any adjournment thereof ("the Meeting") for the purposes set forth in this Proxy Statement and the accompanying Notice. It is anticipated that this Proxy Statement, the Notice and the enclosed form of proxy will be sent to shareholders on or about April 13, 2006.

Proxies

        Proxies in the enclosed form that are properly executed and received by the Company before or at the Meeting and which are not revoked will be voted in accordance with the directions set forth therein. If no direction is made, a proxy that is properly signed and received by the Company and which is not revoked will be voted FOR the election of all nominees for director named herein to serve on the Board until the 2007 annual meeting of shareholders and until their successors are duly elected and qualified, FOR the proposal to approve the amendment to the Company's Restated Articles of Incorporation to increase the number of authorized common shares to 145 million, and FOR the ratification of the appointment of KPMG LLP as the independent registered public accounting firm of the Company for the year ending December 31, 2006. If any other matter, not known or determined at the time of the solicitation of proxies, properly comes before the Meeting, the proxies will be voted in accordance with the discretion of the person or persons voting the proxies. The proxy also confers on the persons named therein discretionary authority to vote with respect to any matters presented at the Meeting for which advance notice was not received by the Company prior to January 31, 2006. Proxies may be revoked by written notice received by the Secretary of the Company at any time before they are voted by delivering to the Secretary of the Company a signed notice of revocation, or a later dated signed proxy, or by attending the Meeting and voting in person by ballot.

Voting Securities

        Shareholders of record at the close of business on March 31, 2006 are entitled to notice of and to vote at the Meeting.

Each Common Share is entitled to one vote on all matters that may properly come before the Meeting.

1


Quorum and Other Matters

        The presence at the Meeting, in person or by proxy, of the holders of a majority of the outstanding Common Shares is necessary to constitute a quorum. Common Shares represented by a properly completed, signed and returned proxy will be counted as present at the Meeting for purposes of determining a quorum, without regard to whether the proxy is marked as casting a vote or abstaining. Common Shares held by nominees which are voted on at least one matter coming before the Meeting will also be counted as present for purposes of determining a quorum, even if the beneficial owner's discretion has been withheld (a "non-vote") for voting on some or all other matters.

        The affirmative vote of a majority of the outstanding Common Shares is required to authorize the proposed amendment to the Company's Amended and Restated Articles of Incorporation to increase the number of authorized Common Shares. All other matters specified in the notice of the Meeting require the approval of the affirmative vote of a majority of the outstanding Common Shares entitled to vote and present, in person or represented by proxy, at the Meeting. An abstention, a broker non-vote or a withholding of authority to vote with respect to the election of directors or the ratification of the appointment of the Company's independent registered public accountants will have the effect of a vote against the proposal.

        An Inspector of Election appointed by the Company will tabulate votes at the Meeting.

        The Board is not aware of any matters that are expected to come before the Meeting other than those referred to in this Proxy Statement. If any other matter properly comes before the Meeting, the proxies will be voted in accordance with the discretion of the person or persons voting the proxies.

Election Procedures; Term

        The directors will be elected by the affirmative vote of the holders of a majority of the outstanding Common Shares present in person or represented by proxy at the Meeting. Unless the authority to vote for the election of directors is withheld as to any or all of the nominees, all Common Shares represented by proxy will be voted for the election of the nominees. If the authority to vote for the election of directors is withheld as to any but not all of the nominees, all Common Shares represented by any such proxy will be voted for the election of the nominees as to whom such authority is not withheld. If a nominee becomes unavailable to serve as a director for any reason before the election, the shares represented by proxy will be voted for such other person, if any, as may be designated by the Board. The Board, however, has no reason to believe that any nominee will be unavailable to serve as a director.

        Any vacancy on the Board occurring after the election may be filled (1) by election at any annual or special meeting of the shareholders called for that purpose, or (2) by a majority of the remaining directors though less than a quorum of the Board, provided that the remaining directors may not fill more than two such director vacancies during the period between any two successive annual meetings of shareholders. A director elected to fill a vacancy will be elected for the unexpired portion of the term of his or her predecessor in office.

        All directors will be elected to serve until the 2007 annual meeting of shareholders and until their successors are duly elected and qualified.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF EACH OF THE NOMINEES TO THE BOARD OF DIRECTORS.

Corporate Governance

        The Company has been built on a culture where integrity is the first and most important value, and this value has long been a part of the Company's corporate identity. We support the initiatives by the United States Congress, the SEC and the NYSE to restore investor confidence and to ensure the credibility and transparency of financial reporting.

        The Company's practices generally reflect corporate governance initiatives that are compliant with existing standards of the NYSE and the corporate governance requirements of the Sarbanes-Oxley Act of 2002, including:

5


        The Board will continue to enhance the Company's governance practices as new ideas and best practices emerge. You can access our current committee charters for our Audit Committee, Compensation Committee and Nominating/Governance Committee, as well as our Code of Conduct applicable to all of the Company's employees, officers and directors, and our Corporate Governance Guidelines, on our website at www.bench.com under "Investor—Governance," or you may obtain print copies of these materials by writing to the Corporate Secretary at Benchmark Electronics, Inc., 3000 Technology Drive, Angleton, Texas 77515, phone 979-849-6550.

        Shareholders and other interested parties may send communications to the Board of Directors, the non-employee directors as a group or individual directors, in each case in care of Benchmark Electronics, Inc., 3000 Technology Drive, Angleton, Texas 77515.

Operation of Board of Directors

        The Board has responsibility for establishing broad corporate policies and reviewing our overall performance rather than day-to-day operations. The Board's primary responsibility is to oversee the management of the Company and, in so doing, serve the best interests of the Company and its shareholders. The Board selects, evaluates and provides for the succession of executive officers and, subject to shareholder election, directors. It reviews and approves corporate objectives and strategies, and evaluates significant policies and proposed major commitments of corporate resources. It participates in decisions that have a potential major economic impact on the Company. Management keeps the directors informed of Company activity through regular written reports and presentations at Board and committee meetings.

        The directors are elected annually by the shareholders and hold office until their successors are elected and qualified. The Amended and Restated Bylaws of the Company provide for a Board of Directors consisting of not less than five, nor more than nine, members, as set from time to time by resolution of the Board of Directors. The Board presently consists of eight members. Following eighteen years as a member of our Board, John C. Custer, has decided to not stand for reelection to the Board. Mr. Custer has been a director of the Company since 1988, and has served in several capacities, including Chairman of the Board from 1991 to 2001. The decision that he would not be a nominee for reelection was not because of any disagreement with the Company or any matter related to the Company's operations, policies or practices. The Board is interviewing candidates to replace

6


Mr. Custer as an independent director, but there is no assurance that he will be replaced. If all of the nominees for election as director are elected at the Meeting, there will be seven directors.

        The NYSE rules require that the Company have a majority of independent directors. The rules provide that no director will qualify as "independent" unless the Board affirmatively determines that the director has no material relationship with the Company and its subsidiaries, either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company. Accordingly, as of the date of this Proxy Statement, the Board has determined that the following nominees are "independent": John W. Cox, Peter G. Dorflinger, Laura W. Lang and Bernee D.L. Strom. The Board has determined that each independent director or nominee had no relationship with the Company other than as a director, shareholder or management, and that none of the express disqualifications contained in the NYSE rules applied to any of them. If the Board identifies a suitable indepenent replacement for Mr. Custer, it intends to increase the size of the Board back to eight and to fill the vacancy created thereby with such individual.

        The Board held seven meetings and took action by written consent one time during 2005. Each of the directors attended at least 75% of such meetings during the period in which he or she was director. Messrs. Nigbor, Fu and Barton are also employees of the Company. They do not participate in any meeting at which their compensation is evaluated. All members of all committees are non-employee directors. In addition to committee meetings, the non-employee directors regularly meet outside the presence of the employee-directors. These executive sessions are currently held either before, after or otherwise in conjunction with the Board's regularly scheduled meetings. Additional executive sessions can be scheduled at the request of the non-employee directors. The director who presides over the executive sessions is chosen by independent directors at the executive session.

        The Board has an Audit Committee, a Compensation Committee and a Nominating/ Governance Committee. Each committee has a charter that has been approved by the Board. Each committee must review the appropriateness of its charter at least annually. Each member of each committee meets the independence requirements of the NYSE.

        The Audit Committee, consisting of Messrs. Cox, Custer and Dorflinger, met nine times during 2005 and each member attended at least 75% of the meetings during the period in which he was a member of such committee. Mr. Cox qualifies as an "audit committee financial expert" under the rules of the SEC. An "audit committee financial expert" is defined as a person who has the following attributes: (i) an understanding of generally accepted accounting principles and financial statements; (ii) the ability to assess the general application of such principles in connection with the accounting for estimates, accruals and reserves; (iii) experience preparing, auditing, analyzing or evaluating financial statements that present a breadth and level of complexity of accounting issues that are generally comparable to the breadth and complexity of issues that can reasonably be expected to be raised by the registrant's financial statements, or experience actively supervising one or more persons engaged in such activities; (iv) an understanding of internal controls and procedures for financial reporting; and (v) an understanding of audit committee functions. The Board, in its business judgment, has determined that Messrs. Cox, Custer and Dorflinger are "independent," as required by applicable listing standards of the NYSE governing the qualifications of the members of audit committees, including the requirements of the Securities Exchange Act of 1934. The function of the Audit Committee is to assist the Board in fulfilling its responsibility to oversee (i) management's conduct of the Company's financial reporting process (including management's development and maintenance of systems of internal accounting and financial controls), (ii) the integrity of the Company's financial statements, (iii) the Company's compliance with legal and regulatory requirements and ethical standards, (iv) the qualifications and independence of the Company's outside auditors and (v) the performance of the Company's internal audit function and the outside auditors; and to prepare the audit committee report required by the rules of the SEC to be included in the Company's annual proxy

7


statement. Additional information regarding the functions performed by the committee is set forth below in the "Report of the Audit Committee."

        The Compensation Committee, consisting of Mr. Dorflinger, Ms. Lang and Ms. Strom, met seven times during 2005 and each member attended at least 75% of the meetings during the period in which he or she was a member of such committee. The functions of the Compensation Committee are to (i) oversee the administration of the compensation plans, in particular the incentive compensation and equity-based plans, of the Company (and, to the extent appropriate, the subsidiaries of the Company), (ii) discharge the Board's responsibilities relating to the compensation of the Company's executives, (iii) review and make recommendations on director compensation and (iv) prepare the annual report on executive compensation required by the rules and regulations of the SEC to be included in the Company's annual proxy statement. Additional information regarding the functions performed by the committee is set forth below in the "Report of the Compensation Committee."

        The Nominating/Governance Committee, consisting of Messrs. Cox and Custer and Ms. Strom, met six times during 2005 and each member attended all of the meetings during the period in which he or she was a member of such committee. The functions of the Nominating/Governance Committee are to (i) identify individuals qualified to become Board members and recommend such individuals to the Board for nomination for election to the Board, (ii) make recommendations to the Board concerning committee appointments, (iii) develop, recommend and annually review corporate governance guidelines for the Company and (iv) oversee corporate governance matters and coordinate an annual evaluation of the Board.

        To be considered by the Nominating/Governance Committee, a director nominee should have experience as a board member or senior executive of a public company or nationally recognized private company. In addition to these minimum requirements, the Nominating/Governance Committee will also evaluate whether the nominee's skills are complementary to the existing Board members' skills, and the Board's needs for operational, management, financial, international, technological or other expertise. The Nominating/Governance Committee typically utilizes a search firm to identify and screen the candidates, do reference checks, prepare a biography for each candidate for the Nominating/Governance Committee to review and coordinate interviews. The Nominating/Governance Committee, the Chairman of the Board and executive officers interview candidates that meet the criteria, and the Nominating/Governance Committee selects nominees who best suit the Board's needs. The Nominating/Governance Committee will consider for nomination to the Board candidates suggested by the shareholders, provided that such recommendations are submitted and received by us at our principal executive offices at 3000 Technology Drive, Angleton, Texas 77515, with an appropriate biographical summary, in accordance with the requirements described below under "Date of Submission of Shareholder Proposals."

        All members of the Board attended the Annual Meeting of Shareholders in 2005. The Board does not have a formal written policy requiring members to attend the Shareholders' Meeting, although all members have traditionally attended.

Audit Committee Report to Shareholders

        The Audit Committee of the Board is responsible for providing independent, objective oversight of the Company's accounting functions and internal controls. The Audit Committee currently is composed of three non-employee directors, Messrs. Cox, Custer and Dorflinger, each of whom is an "independent director" under the rules of the NYSE governing the qualifications of the members of audit committees. Mr. Cox qualifies as an "audit committee financial expert" under the rules of the SEC. The Audit Committee operates under a written charter, attached to this proxy statement as Appendix A, previously approved by the Board. The Audit Committee met nine times during 2005 and each member attended at least 75% of the meetings during the period in which he was a member of

8


such committee. The meetings were designed to facilitate and encourage communication between members of the Audit Committee and management as well as private communication between the members of the Audit Committee and our internal auditors, and our independent registered public accounting firm, KPMG LLP.

        Management is responsible for the Company's internal controls and financial reporting process. The independent accountants are responsible for performing an independent audit of the Company's consolidated financial statements in accordance with generally accepted auditing standards and issuing a report thereon. The Audit Committee's responsibility is to monitor and oversee these processes.

        In connection with these responsibilities, the Audit Committee met with management and KPMG LLP to review and discuss the December 31, 2005 audited financial statements and matters related to Section 404 of the Sarbanes-Oxley Act of 2002. The Audit Committee also discussed with the independent accountants the matters required by Statement on Auditing Standards No. 61, Communication with Audit Committee. The Audit Committee also received written disclosures and the letter from the independent accountants required by Independence Standards Board Standard No. 1, Independence Discussions with Audit Committees, and the Audit Committee discussed with the independent accountants that firm's independence.

        Based upon the Audit Committee's review of the audited consolidated financial statements, discussions with management and the independent accountants, and the Audit Committee's review of the representations of management and discussions with the independent accountants as set forth above, the Audit Committee recommended that the Board include the audited consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2005, filed with the SEC on March 13, 2006.

        The following table presents fees for professional services provided by KPMG LLP for 2005 and 2004, all of which were pre-approved by the audit committee.

Audit Committee Pre-Approval Policy

        The Audit Committee has adopted a specific policy for pre-approval of services to be provided by the Company's independent registered public accounting firm. Under the policy, in addition to the annual audit engagement terms and fees, the Audit Committee pre-approves specific types of audit, audit-related, tax and non-audit services to be performed by the independent registered public accounting firm throughout the year, as well as fee ranges for each specific service, based on the Audit Committee's determination that the provision of the services would not be likely to impair the accounting firm's independence. Unless a type of service to be provided by the independent registered public accountant has received general pre-approval, it will require specific pre-approval by the Audit Committee. Any proposed services exceeding pre-approved cost levels will require specific pre-approval by the Audit Committee. The pre-approval is effective for 12 months from the date of pre-approval, unless the Audit Committee specifically approves the provision of such services for a different period. The policy permits the Audit Committee to delegate pre-approval authority to one or more of its members to ensure prompt handling of unexpected matters, with such delegated pre-approvals to be reported to the Audit Committee at its next meeting. The policy also contains a list of prohibited non-audit services and requires that the independent registered public accounting firm ensure that all audit and non-audit services provided to the Company have been pre-approved by the Audit Committee.

        The Audit Committee of the Company's Board has considered whether the services provided by KPMG LLP as they related to other non-audit services are compatible with maintaining the accounting firm's independence. The Audit Committee has determined that provision of those services is compatible with maintaining the independence of KPMG LLP as the Company's registered public accounting firm.

PROPOSAL 2

AMENDMENT TO THE COMPANY'S
RESTATED ARTICLES OF INCORPORATION TO INCREASE
THE NUMBER OF AUTHORIZED COMMON SHARES

        The Board is seeking shareholder approval to amend Article Four of the Company's Amended and Restated Articles of Incorporation (the "Articles of Incorporation") to increase the number of authorized Common Shares of the Company from 85 million to 145 million shares. This proposal has been unanimously approved by the Board, subject to approval by the shareholders of the Company. If the proposed amendment is authorized, the text of Section 4.1 of Article Four of the Articles of Incorporation would be amended to read as follows:

Reasons for the Proposed Amendment

        During 2003, the Company issued 2,992,000 Common Shares upon the conversion of its 6% Convertible Subordinated Notes. In March 2006, the Board declared a three-for-two stock split in the form of a stock dividend. Shareholders of record at the close of business March 27, 2006 will receive one additional share for every two shares owned. The additional shares will be distributed on April 3, 2006. As of March 31, 2006, giving pro forma effect to the three-for-two stock split as if it had occurred on March 31, 2006, there were 64,111,543 Common Shares issued and outstanding, 111,339 treasury shares and 12,208,918 shares reserved for issuance upon exercise of outstanding or available options, leaving 8,568,200 shares unrestricted and available for issuance by the Company from time to time. Other than as described above, the Company has no present plans, arrangements or understandings to issue any additional Common Shares.

        The proposed increase in the authorized Common Shares has been recommended by the Board to ensure that an adequate supply of authorized and unissued shares is available for general corporate needs, such as employee benefit plans, the conversion of other securities (such as Preferred Stock) that may be issued by the Company, future stock splits, stock dividends and other distributions to shareholders, raising additional capital, financing arrangements, and acquisitions by the Company if favorable opportunities become available. Each officer and director has been granted, and may be granted, options under the Company's employee benefit plan or non-employee director stock option plan. Increasing the number of authorized shares would allow the Company to consider increasing the number of options to purchase common shares issued to the officers and directors of the Company under such plans.

Possible Effects of the Proposed Amendment

        If approved by the shareholders, the additional authorized Common Shares would be available for issuance at the discretion of the Board without further shareholder approval (subject to applicable rules of the NYSE), without the delay and expense incident to holding a special meeting of shareholders to consider any specific issuance. However, the rules of the NYSE generally require shareholder approval in the following situations: (i) with respect to a stock option or purchase plan, or any other arrangement, pursuant to which officers or directors may acquire stock (subject to certain exceptions); (ii) prior to the issuance of Common Shares, or of securities convertible into or exercisable for Common Shares, to (a) a director, officer of substantial security holder of the Company (a "Related Party"), (b) a subsidiary, affiliate or other closely-related person of a Related Party, or (c) any company or entity in which a Related Party has a substantial direct or indirect interest; (iii) prior to the issuance of Common Shares, or of securities convertible into or exercisable for Common Shares (except for a

11


public offering of Common Shares for cash) that would result in an increase in the number of shares or voting power of the outstanding shares by 20% or more; or (iv) prior to an issuance that will result in the change of control of the issuer.

        Current holders of Common Shares have no preemptive rights, which means that current shareholders do not have a prior right to purchase any new issue of capital stock of the Company in order to maintain their proportionate ownership thereof. The effects of the authorization of additional Common Shares may also include dilution of the voting power of currently outstanding shares and reduction of the portion of dividends and of liquidation proceeds payable to the holders of currently outstanding Common Shares.

        In addition, the Board could use the authorized but unissued Common Shares to create impediments to a takeover or a change of control of the Company. Under certain circumstances, such shares could be used to create voting impediments or to frustrate persons seeking to effect a takeover or otherwise gain control of the Company. For example, the Company might seek to frustrate a takeover attempt by making a private sale of a large block of shares to a third party who was opposed to such an attempt. The increase in authorized shares might also be considered as having the effect of discouraging an attempt by a third party to acquire control of the Company, through the acquisition of a substantial number of shares, since the issuance of any shares could be used to dilute the ownership of the Company's voting shares held by such third party. Accordingly, an effect of the increase in the number of authorized Common Shares may be to deter a future takeover attempt. However, this proposal is not made in response to any effort of which the Company is aware to accumulate its Common Shares or to obtain control of the Company nor does the Company intend to use the additional Common Shares to oppose a hostile takeover attempt or to delay or prevent changes in control of management.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSAL TO APPROVE THE AMENDMENT TO THE COMPANY'S RESTATED ARTICLES OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED COMMON SHARES TO 145 MILLION SHARES.


PROPOSAL 3

RATIFICATION OF APPOINTMENT OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

        The Board has appointed KPMG LLP as the independent public accounting firm of the Company for the year ending December 31, 2006. The shareholders will be asked to ratify the appointment of KPMG LLP at the Meeting. The ratification of such appointment will require the affirmative vote of the holders of a majority of the outstanding Common Shares entitled to vote and present, in person or represented by proxy, at the Meeting. Representatives of KPMG LLP will be present at the Meeting, will be given an opportunity to make a statement (if they desire to do so) and will be available to respond to appropriate questions.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE PROPOSAL TO RATIFY THE APPOINTMENT OF THE INDEPENDENT PUBLIC ACCOUNTING FIRM.

Compensation of Directors

        Employee directors have never received any additional compensation for serving on the Board above the compensation they received for serving as officers of the Company, as described under "Executive Compensation and Other Matters."

        The following table shows non-employee director compensation as determined by the Board upon the recommendation of the Compensation Committee.

Annual Board Retainer(1)   $ 60,000
Annual Committee Chair Retainer(1)   $ 5,000
Payment per Board meeting attended   $ 1,000
Payment per Committee meetings attended   $ 1,000

(2)
Maximum annual stock option grant under the 2002 Plan as adjusted for stock splits.

        The Company also reimburses its non-employee directors for their reasonable travel expenses in attending such meetings.

        In December 1994, the Board adopted the Benchmark Electronics, Inc. 1994 Stock Option Plan for Non-Employee Directors (the "1994 Plan") for the benefit of members of the Board who are not

14


employees of the Company or its Affiliates (as defined in the 1994 Plan). The purpose of the 1994 Plan was to encourage ownership of the Company's Common Shares by eligible non-employee directors of the Company, to provide increased incentive for such directors to render services and to exert maximum effort for the business success of the Company and to further strengthen the identification of directors with the shareholders of the Company. The 1994 Plan terminated in December 2004. The 1994 Plan was replaced in 2002 by the Benchmark Electronics, Inc. 2002 Stock Option Plan for Non-Employee Directors (the "2002 Plan"), and no additional grants may be made under the 1994 Plan. The Company has outstanding options with respect to 56,775 Common Shares under the 1994 Plan.

        After giving effect to the Company's stock split in 2003, the 2002 Plan provides for the granting of a stock option to purchase up to 10,500 Common Shares upon the occurrence of the non-employee director's election or reelection to the Board. After giving effect to the Company's stock split in 2003, the maximum number of Common Shares for which options may be granted under the 2002 Plan is 450,000. No awards may be granted under the 2002 Plan after the expiration of ten years from February 26, 2002, the date of its adoption by the Board. The 2002 Plan remains in effect as to awards made prior to the expiration of ten years until such awards have been satisfied or have expired. All awards under the 2002 Plan are fully vested upon the date of grant. The exercise price per common share of options granted under the 2002 Plan will be the fair market value of a Common Share on the date such option is granted.

        Upon their election as directors in May 2005, each of Messrs. Cox, Custer and Dorflinger and Ms. Strom received a grant under the 2002 Plan of an option to purchase 10,000 Common Shares, and upon her election as a new director Ms. Lang received a grant to purchase 10,500 Common Shares, at an exercise price of $28.30 per share, which was the market price of the Common Shares on the date of the grant. The Company has outstanding options with respect to 134,000 Common Shares under the 2002 Plan.

        Within the later of (i) three years after joining the Board or (ii) August 13, 2006, directors are expected to own common shares of the Company having a value equal to three times the non-employee director's annual board retainer.

Board Compensation Committee Report on Executive Compensation

        The Company's executive compensation program is administered by the Compensation Committee, a committee of the Board composed of non-employee directors listed below this report. The Compensation Committee is responsible for recommending to the full Board the compensation of the Chief Executive Officer of the Company, determining the compensation of the other executive officers of the Company, and administering the Company's employee benefit plans. None of the members of the Compensation Committee has any interlocking or other relationships with the Company that would call into question their independence as Compensation Committee members. The Compensation Committee operates under a written charter previously approved by the Board.

        Compensation Policies and Programs.    The Compensation Committee believes that the goals of the executive compensation program should be to align executive compensation with the Company's long-term business objectives and performance and to enable the Company to attract, retain and reward executive officers who contribute to the long-term success of the Company. The Compensation Committee believes that the best way to achieve these goals is by aligning the financial interests of the Company's executive officers closely to the interests of the Company's shareholders through a combination of annual cash incentives and stock-based incentive compensation, while providing the executive officers with base salary compensation at levels that are competitive with, but which do not exceed, prevailing standards. The compensation of the Company's executive officers is reviewed and

15


approved annually by the Compensation Committee. The Company's executive compensation program is based on three elements, each of which is determined in part by corporate performance:

        Corporate performance is evaluated by reviewing the extent to which strategic and business plan goals are met, including the relationship between the Company's net income and sales. The Compensation Committee believes that total executive compensation opportunities are competitive and at the median with those offered by employers in the peer group of companies with which the Company compares its performance in the Performance Graph following this report, but with less emphasis on base salary compensation than such other employers.

        Cash Base Salary.    The Company has employment agreements with Messrs. Nigbor, Fu and Barton and Ms. Delly. The agreements provide for annual base salaries, subject to adjustment for subsequent twelve-month periods as determined by the Compensation Committee, based on its review of base salaries provided to executive officers of other employers in the Company's industry and certain corporate performance factors such as the Company's net income and sales and historical salary progression. The employment agreements with Messrs. Fu and Barton and Ms. Delly expire December 1, 2008 and automatically renew thereafter for successive one-year terms (each such renewal term, a "Renewal Term"), unless either party gives to the other written notice of termination no fewer than ninety days prior to the expiration of any such Renewal Term. The employment agreement with Mr. Nigbor expires January 1, 2009 and automatically renews thereafter for successive one-year terms, unless either party gives to the other written notice of termination no fewer than ninety days prior to the expiration of any such Renewal Term. Messrs. Nigbor and Barton's current annual base salary under their employment agreements is $250,000 through August 1, 2006. Mr. Fu's current annual base salary through August 1, 2006 is $590,000. Ms. Delly's current annual base salary is $410,000 through August 1, 2006. The employment agreements also provide for payment of severance. If employment is terminated by the Company without cause prior to the end of the then current Renewal Term, severance will be paid for a period of one year beginning on the date of termination.

        Cash Bonus.    The Company has incentive bonus plans for the benefit of its employees, including executive officers. The total amount of cash bonus awards to be made under these incentive bonus plans for any period depends primarily on the Company's earnings before income tax for that period.

        For any plan period, the earnings before income tax must meet or exceed, or in combination with other factors satisfy, levels targeted by the Company in its business plan, as established at the beginning of each fiscal year, for any bonus awards to be made. The Compensation Committee has the authority to determine the total amount of bonus awards, if any, to be made to the Company's corporate employees for any plan year based on its evaluation of the Company's financial condition and results of operations, the Company's business and prospects, and such other criteria as it may determine to be relevant or appropriate. The Compensation Committee has the authority to determine the specific amounts of bonus awards to be made to the Company's executive officers and other key employees based on its evaluation of each such employee's position, performance, service and such other criteria as it may determine to be relevant or appropriate.

        In 2005, the Company's sales, net income and return on invested capital exceeded the levels targeted by the Company in its 2005 business plan. The Compensation Committee elected to award bonuses of $500,850 to Mr. Nigbor, $642,007 to Mr. Fu, $267,355 to Ms. Delly and $140,625 to Mr. Barton.

        Stock Purchase Plan.    In April 1999, the Company adopted the Benchmark Electronics, Inc. Employee Stock Purchase Plan (the "Purchase Plan"). Under the Purchase Plan, employees meeting

16


specific employment qualifications are eligible to participate and can purchase shares semi-annually through payroll deductions at the lower of 85% of the fair market value of the Common Shares at the commencement or end of the offering period. The Purchase Plan permits eligible employees to purchase Common Shares through payroll deductions for up to the lesser of 17% of qualified compensation or $25,000. The executive officers, including the Chief Executive Officer, are eligible to participate in the Purchase Plan on the same basis as all other employees. On November 30, 2005, the Board of the Company approved the termination of the Purchase Plan as of December 31, 2005.

        Stock Awards Plan.    The Compensation Committee believes that stock options and other methods of equity-based incentive compensation are of increasing importance in attracting and retaining employees and executives and are critical in motivating the long-term creation of shareholder value because methods of equity-based incentive compensation focus executive attention on share price as the primary measure of performance. In 2000, the Company adopted, and its shareholders approved, the Benchmark Electronics, Inc. 2000 Stock Awards Plan (the "2000 Plan") for the benefit of its officers and employees, its affiliates, and consultants to the Company and its affiliates (the "Eligible Participants"). The 2000 Plan replaced the 1990 Stock Option Plan that expired in May 2000. The 2000 Plan is administered by the Compensation Committee. The purpose of the 2000 Plan is to encourage ownership of Common Shares by the Eligible Participants to provide increased incentive for such Eligible Participants to render services and to exert maximum effort for the business success of the Company and to strengthen identification of such Eligible Participants with the shareholders for the purpose of maximizing shareholder value. The 2000 Plan utilizes vesting periods to encourage its executive officers and eligible employees to continue in the employ of the Company. The Compensation Committee subjectively determines the number of shares to be covered by options granted to its employees and executive officers, including the Chief Executive Officer. Stock option grants to the Company's Chief Executive Officer and other executive officers are not made automatically each year and are not considered to be a part of normal annual compensation. The amount and terms of options already held by an executive officer generally are not significant factors in the Compensation Committee's determination of whether and how many options should be granted to the executive officer.

        Stock option grants provide an incentive that focuses the executives' attention on managing the Company from the perspective of an owner with an equity stake in the business. Accordingly, these stock options are tied to the future performance of the Company's Common Shares and provide value to the recipient only when the price of the Company's Common Shares increase above the option grant price.

        IRS Limits on Deductibility of Compensation.    An income tax deduction under Section 162(m) of the Internal Revenue Code will generally be available for annual compensation in excess of $1 million paid to the executive officers only if that compensation is "performance-based" and complies with certain other tax law requirements. Although the Compensation Committee considers deductibility issues when approving executive compensation elements, we believe that the other compensation objectives, such as attracting, retaining and providing incentives to qualified managers, are important and may supersede the goal of maintaining deductibility. Consequently, the Compensation Committee may make compensation decisions without regard to deductibility when it is in the best interests of the Company and its shareholders to do so.

BENCHMARK ELECTRONICS, INC.
PROXY STATEMENT

APPENDIX A

Charter of the Audit Committee of the Board of Directors

Mission Statement

        The primary purpose of the Audit Committee (the "Committee") of the Board of Directors (the "Board") of Benchmark Electronics, Inc. (the "Company") is:

        (A)  to assist the Board in fulfilling its responsibility to oversee (i) management's conduct of the Company's financial reporting process (including management's development and maintenance of systems of internal accounting and financial controls), (ii) the integrity of the Company's financial statements, (iii) the Company's compliance with legal and regulatory requirements and ethical standards, (iv) the qualifications and independence of the Company's outside auditors and (v) the performance of the Company's internal audit function and the outside auditors; and

        (B)  to prepare the audit committee report required by the rules of the Securities and Exchange Commission (the "SEC") to be included in the Company's annual proxy statement.

Membership

        The Committee shall consist of at least three directors, the exact number to be determined from time to time by the Board.

        The Committee's composition shall meet the independence and expertise requirements for audit committees imposed by the listing standards of the New York Stock Exchange (the "NYSE"), Section 10A(m)(3) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") and any applicable rules or regulations of the SEC, in each case as in effect from time to time. The Board shall endeavor to have at least one member of the Committee be a financial expert as defined by the SEC.

        The members of the Committee shall be appointed by a majority vote of the Board from among its members based on the recommendations of the Nominating/Governance Committee and shall serve until such member's successor is duly appointed and qualified or until such member's resignation or removal by a majority vote of the Board.

        No member of the Committee may serve simultaneously on the audit committees of more than two other public companies, unless the Board determines that such simultaneous service would not impair such director's ability to serve effectively on the Committee and such determination is disclosed in the Company's annual proxy statement.

Authority and Responsibilities

        The Committee's function is not to replace the Company's management, internal auditors and outside auditors, but rather one of oversight. It is the responsibility of the Company's management to prepare the Company's financial statements and to develop and maintain adequate systems of internal accounting and financial controls, and it is the internal and outside auditors' responsibility to review, and when appropriate, audit or attest to these financial statements and internal controls. The Committee recognizes that the financial management and the internal and outside auditors have more knowledge and information about the Company than do Committee members. Consequently, in carrying out its oversight responsibilities, the Committee cannot provide any expert or special assurance as to the Company's financial statements or internal controls or any professional certification as to the outside auditors' work.

A-1


        In carrying out its oversight responsibilities, the Committee shall undertake the following activities and have the following authority (in addition to any others that the Board may from time to time delegate to the Committee):

A-2

A-3


A-4


Structure and Operations

        The Committee shall designate one member of the Committee to act as its chairperson. The Committee shall meet in person or telephonically at least quarterly at such times and places determined by the Committee chairperson, with further meetings to occur, or actions to be taken by unanimous written consent, when deemed necessary or desirable by the Committee or its chairperson. The chairperson, with input from the other members of the Committee and, where appropriate, members of management and outside advisors, shall set the agendas for Committee meetings.

        The Committee may request that any directors, officers or other employees of the Company, or any other persons whose advice and counsel are sought by the Committee, attend any meeting of the Committee to provide such pertinent information as the Committee requests. The Committee may exclude from its meetings any persons it deems appropriate.

        The Committee may form and delegate authority to subcommittees. In particular, the Committee may delegate to one or more of its members the authority to pre-approve audit and/or non-audit services, provided that the decisions of any member(s) to whom pre-approval authority is delegated shall be presented to the Committee at the next Committee meeting.

        The Committee shall maintain minutes or other records of its meetings and shall give regular reports to the Board on these meetings and such other matters as required by this Charter or as the Board shall from to time specify.

        Except as expressly provided in this Charter, the Company's by-laws or the Company's Corporate Governance Guidelines, or as required by law, regulation or NYSE listing standards, the Committee shall set its own rules of procedure.

Compensation

        No member of the Committee may receive, directly or indirectly, any compensation from the Company other than (i) fees paid to directors for service on the Board (including customary perquisites and other benefits that all directors receive), (ii) additional fees paid to directors for service on a committee of the Board (including the Committee) or as the chairperson of any committee and (iii) a pension or other deferred compensation for prior service that is not contingent on future service on the Board. In addition, payments in connection with ordinary course commercial business relationships determined by the Board to be immaterial and received from the Company to an entity with which a director has a relationship will not preclude such director from serving as a member.
