20162017 ANNUAL MEETING OF STOCKHOLDERS

September 16, 201615, 2017

PROXY STATEMENT

GENERAL

This Proxy Statement and the accompanying proxy are furnished to stockholders of SigmaTron International, Inc. (the “Company”) in connection with the solicitation of proxies by the Company’s Board of Directors for use at the 20162017 Annual Meeting of Stockholders (sometimes referred to herein as the “Meeting”) to be held at SigmaTron International, Inc., located at 2201 Landmeier Road, Elk Grove Village, Illinois, 60007, at 10:00 a.m. local time, on Friday, September 16, 2016,15, 2017, for the purposes set forth in the accompanying Notice of Meeting. This Proxy Statement, the form of proxy included herewith and the Company’s Annual Report to Stockholders for the fiscal year ended April 30, 20162017 are being mailed to stockholders on or about August 12, 2016.11, 2017.

Stockholders of record at the close of business on July 29, 201628, 2017 are entitled to notice of and to vote at the Meeting. On such date there were outstanding 4,183,9554,195,813 shares of common stock, par value $.01 per share. The presence, in person or by proxy, of the holders of a majority of the shares of common stock outstanding and entitled to vote at the Meeting is necessary to constitute a quorum. In deciding all questions, each holder of common stock shall be entitled to one vote, in person or by proxy, for each share held on the record date.

If you are a stockholder of record (that is, if you hold your shares in certificate form or if your shares are registered in your name on the books of the Company’s transfer agent, American Stock Transfer and Trust Company, as of the close of business on July 29, 2016)28, 2017), and attend the Meeting, you may deliver your completed proxy card in person. However, if you hold your shares in “street name” (not registered in your name): (a) you must return your voting instructions to your broker or nominee so that the holder of record can be instructed how to vote those shares; or (b) if you wish to attend the Meeting and vote in person, you must obtain and bring to the Meeting a proxy signed by the record holder giving you the right to vote the shares in order to be able to vote at the Meeting. (You maynot use the voting instruction form provided by your broker or nominee to vote in person at the Meeting.) For directions to the meeting, please contact the Company at 847-956-8000.

Votes cast by proxy or in person at the Meeting will be tabulated by the election inspector appointed for the Meeting and will determine whether or not a quorum is present. The election inspector will treat abstentions as shares that are present and entitled to vote but as not voted for purposes of determining the approval of any matter submitted to the stockholders for a vote. Abstentions will have the same effect as negative votes on (i) the proposal to ratify the selection of the auditor, (ii) the proposal related to approve the advisory voteapproval on the compensation of the Company’s Named Executive Officers, and (iii) the proposal related to approve the advisory voteapproval regarding the recommendation to select a three year frequency of future advisory votes on executive compensation. If a broker indicates on the proxy that it does not have discretionary authority as to certain shares to vote on a particular matter, or chooses not to exercise its authority (“Broker Non-Votes”), those shares will not be considered as present and entitled to vote with respect to that matter, unless it is a routine matter. Under NASDAQ rules, ratification of the appointment of the Company’s independent auditors is a routine matter, while the election of directors and the advisory votes on executive compensation and the frequency of that rate are nonroutine matters.

Properly executed proxies will be voted in the manner directed by the stockholders. If no direction is indicated, such proxies will be voted (i) FOR the election of each nominee named under the caption “Election of two Class IIIII Directors” as set forth therein as a Director of the Company, (ii) FOR the ratification of the selection of BDO USA, LLP as the Company’s registered public accountants, (iii) FOR the advisory vote on the approval of the compensation of the Company’s Named Executive Officers and (iv) FOR a three-year frequency of advisory votes on executive compensation. If a quorum is present at the Meeting, Directors will be elected by

1

a plurality of the votes cast. The ratification of the selection of auditors and the non-binding, advisory vote on the proposal related to the vote on the compensation of the Company’s Named Executive Officers requires an affirmative vote by

1

holders of a majority of the shares present at the Meeting in person or by proxy and entitled to vote. The non-binding, advisory recommendation of the shareholdersstockholders for the frequency of holding future advisory votes on executive compensation will be that choice which receives a plurality of the votes cast. All other matters submitted for stockholder approval at the Meeting will be decided by the affirmative vote of a majority of the shares present, in person or by proxy, at the Meeting and entitled to vote on the subject matter. Any proxy may be revoked by the stockholder at any time prior to the voting thereof by notice in writing to the Secretary of the Company, either prior to the Meeting (at the above address) or at the Meeting if the stockholder attends in person. A later dated proxy will revoke a prior dated proxy.

All expenses incurred in the solicitation of proxies will be borne by the Company. In addition to the use of the mail, proxies may be solicited on behalf of the Company by Directors, Officers and Employees of the Company by telephone, e-mail or telecopy. The Company will reimburse brokers and others holding common stock as nominees for their expenses in sending proxy material to the beneficial owners of such common stock and obtaining their proxies.

Important Notice Regarding the Availability of Proxy Materials for the Stockholders Meeting to be held on September 16, 2016.15, 2017.

The Proxy Statement is available at http://www.sigmatronintl.com

As of the date of this Proxy Statement, the Board of Directors knows of no other business which will be presented for consideration at the Meeting. If other proper matters are presented at the Meeting, however, it is the intention of the proxy holders named in the enclosed form of proxy to take such actions as shall be in accordance with their best judgment.

The information contained in this Proxy Statement relating to the occupations and security holdings of Directors and Officers of the Company and their transactions with the Company is based upon information received from each individual as of July 29, 2016.28, 2017.

2. PROPOSAL TO RATIFY SELECTION OF INDEPENDENT

REGISTERED PUBLIC ACCOUNTANTS

The Board of Directors will recommend at the Annual Meeting that the stockholders ratify the appointment of the firm of BDO USA, LLP to audit the accounts of the Company for the current fiscal year. Representatives of that firm are expected to be present at the Meeting, have the opportunity to make a statement, if they desire to do so, and be available to respond to appropriate questions. BDO USA, LLP was recommended by the Audit Committee and the Board of Directors as the independent registered public accountants for the fiscal year 2017.2018.

In connection with the audits for the years ended April 30, 20162017 and 2015,2016, the Company has had no disagreements with BDO USA, LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements if not resolved to the satisfaction of BDO USA, LLP would have caused it to make reference thereto in its report on the consolidated financial statements for 20162017 and 2015.2016.

The ratification of the selection of auditors requires an affirmative vote by holders of a majority of the shares present at the Meeting in person or by proxy and entitled to vote. Broker Non-Votes, while considered present at a meeting and included in the determination of whether a quorum exists, are not considered entitled to vote. Thus, Broker Non-Votes will have no effect on this proposal. Abstentions will have the same effect as negative votes.

The Board of Directors recommends that you vote in favor of ratification of the selection of BDO USA, LLP as the Company’s registered public accountants for the fiscal year ending April 30, 2017.2018.

AUDIT FEES AND AUDIT RELATED FEES

FISCAL YEARS 20162017 AND 20152016 AUDIT FIRM FEE SUMMARY

CORPORATE GOVERNANCE

Our Board of Directors determined that each of Messrs. Horek, Mantia, Plante, Rieck and Vyas are independent under the rules of Nasdaq. As a result, our Board of Directors currently has a majority of independent Directors under the rules of Nasdaq. Our Board of Directors has determined that our independent Directors shall have regularly scheduled meetings at which only the independent Directors are present. Generally, the independent Directors meet separately at each regularly scheduled Board meeting.

Director Committees; Board Meetings

In accordance with the requirements of the Exchange Act and rules promulgated thereunder, the Board of Directors has established an Audit Committee, a Compensation Committee and a Nominating Committee. The Audit Committee Charter, Compensation Committee Charter and the Nominating Committee Charter are available on the Company’s website atwww.sigmatronintl.com. The Company believes that the composition of these committees meets the criteria for independence under, and the functioning of these committees complies with, the applicable requirements of the current listing standards of Nasdaq and the SEC’s rules and regulations promulgated under the Sarbanes-Oxley Act of 2002 as set forth below.

The functions of the Audit Committee are to: (1) select and evaluate the performance of the independent accountants; (2) review the audits of the financial statements of the Company and the scope of the audit; (3) review with the independent accountants the corporate accounting and financial reporting practices and policies and recommend to whom reports should be submitted within the Company; (4) review with the independent accountants their final report; (5) review with the internal and independent accountants overall accounting and financial controls; and (6) be available to the independent accountants and management for consultation purposes. The Audit Committee is currently comprised of three members: Messrs. Rieck (Chairman), Horek and Plante. The Board of Directors has determined that each of the members of the Audit Committee is independent under the rules of the SEC and Nasdaq. Mr. Rieck has been determined to be an Audit Committee financial expert as defined in Item 407 of Regulation S-K promulgated under the Exchange Act. The Board of Directors has adopted a written charter for the Audit Committee and is available on the Company’s website atwww.sigmatronintl.com. The report of the Audit Committee to the Stockholders is included in this Proxy Statement under the heading “Report of the Audit Committee.”

The functions of the Compensation Committee are to review and recommend to the Board of Directors annual salaries and bonuses for all Executive Officers of the Company, to review and recommend to the Board of Directors compensation for the Directors, to review and recommend to the Board of Directors the terms and conditions of all employee benefit plans or changes thereto and to administer the Company’s stock option plans. While the Chief Executive Officer of the Company may make recommendations regarding such salaries, compensation and terms and conditions of employment, the Compensation Committee reviews any such recommendations independently and is responsible for making final recommendations to the full Board of Directors. Messrs. Mantia (Chairman), Plante, and Vyas are members of the Compensation Committee. The Board of Directors has determined that each of the members of the Compensation Committee is independent under the listing standards of Nasdaq. The Compensation Committee has authority to select and hire outside consultants and shall have full access to the Human Resources Department or other Company employees to assist in the evaluation of executive officer compensation and may approve the fees and other retention terms of any consultants hired by the Compensation Committee. The Compensation Committee may also obtain advice and assistance from legal, accounting or other advisors selected by the Compensation Committee. The Board of Directors has adopted a written charter for the Compensation Committee and is available on the Company’s website atwww.sigmatronintl.com.

The functions of the Nominating Committee are to: (1) review and recommend to the Board of Directors the size and composition of the Board of Directors and a slate of nominees for each election of members to the Board of Directors; (2) review and recommend changes to the number, classification and term of Directors; (3) identify and recommend to the Board of Directors candidates to fill appointments to Board committees; (4) develop, assess and make recommendations to the Board of Directors concerning appropriate corporate governance policies; (5) identify and recommend to the Board of Directors candidates to fill a vacancy in the offices of President and Chief Executive Officer; and (6) review nominations by stockholders with regard to the nomination process and to establish the procedures by which stockholder candidates will be considered. The members of the Nominating Committee are Messrs. Vyas (Chairman), Horek and Rieck. The Board of Directors has determined that each of the members of the Nominating Committee is independent under the Nasdaq Stock Market, Inc. listing standards.

The Nominating Committee begins the process of identifying Director candidates by evaluating the current composition of the Board, the Company’s operating requirements, and the long-term interests of the Company’s

11

stockholders. The Nominating Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. In the case of incumbent Directors whose terms of office are set to expire, the Nominating Committee reviews such Directors’ overall service during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such Directors’ independence. The Nominating Committee meets to discuss and consider each candidate’s qualifications and then selects those it considers to be appropriate nominees by majority vote for recommendation to the Board. To date, the Nominating Committee has not paid a fee to any third party to assist in the process of identifying or evaluating Director candidates.

In evaluating and determining whether to recommend a person as a candidate for election as a Director, the Nominating Committee’s criteria reflects the requirements of the Nasdaq rules with respect to independence as well as the following factors: the needs of the Company with respect to the particular talents and experience of its Directors; personal and professional integrity of the candidate; the level of education and/or business experience of the candidate; broad-based business acumen of the candidate; the candidate’s level of understanding of the Company’s business and the electronic manufacturing services industry; the candidate’s abilities for strategic thinking and willingness to share ideas; and the Board of Directors’ need for diversity of experiences, expertise and background. The Nominating Committee will use these criteria to evaluate all potential nominees.

The Company does not have a diversity policy with respect to its Directors. However, in considering whether to recommend any Director nominee, including candidates recommended by stockholders, the Nominating Committee will consider the factors above, including the candidate’s diversity of experiences, expertise, ethnicity, gender and background. The Nominating Committee does not assign specific weights to particular criteria, and no particular criterion is necessarily applicable to all prospective nominees. The Company believes that the backgrounds and qualifications of the Directors, considered as a group, should provide a significant mix of experience, knowledge and abilities that will allow the Board of Directors to fulfill its responsibilities.

The Nominating Committee will consider proposed nominees whose names are submitted to it by stockholders. The Nominating Committee has not adopted a formal process for that purpose because it believes that the Nominating Committee’s process for considering stockholder nominees has been and remains adequate. Historically, stockholders have not proposed any nominees. The Nominating Committee intends to review periodically whether a formal process should be adopted, including whether all stockholder nominations comply with the notice provisions of the Company’s by-laws which generally require that such notice be received by the Secretary of the Company not less than 60 days and not more than 90 days prior to a regularly scheduled Annual Meeting of Stockholders, or within 10 days after receipt of notice of an Annual Meeting of Stockholders if the date of such meeting has not been publicly disclosed within 70 days prior to the meeting date.

Board Meetings

The Board of Directors held 2114 meetings either in person or by telephone conference during the fiscal year ended April 30, 2016.2017. The Compensation Committee held 5 meetings in person or by telephone conference and the Audit Committee held 910 meetings in person or by telephone conference during the fiscal year 2016.2017. The Nominating Committee held 1 meeting during the fiscal year 2016.2017. All Directors attended at least 75% of the meetings of the Board and each of the committees of which they were members. In fact, all Directors attended at least 90% of the meetings of the Board and each of the committees of which they were members. The Company has a policy of encouraging all Directors to attend in person the Annual Meeting of Stockholders. All Directors attended the Company’s 20152016 Annual Meeting of Stockholders.

Board Leadership Structure and Role in Risk Oversight

The Company believes that the service of Gary R. Fairhead as both Chairman of the Board and Chief Executive Officer is in the best interest of the Company and its stockholders. Mr. Fairhead possesses detailed and

12

in-depth knowledge of the opportunities and challenges facing the Company, and is thus best positioned to develop agendas that ensure that the Board’s time and attention are focused on the most critical matters. The Board believes his role as Chairman of the Board and Chief Executive Officer promotes consistent leadership, engenders accountability, and enhances the Company’s ability to communicate its message and strategy clearly and consistently to its stockholders, employees, and customers. The Company believes the Board’s administration of its risk oversight function to date has had a positive effect on the Board’s leadership structure.

Consistent with the Company’s corporate governance guidelines and because Mr. Fairhead is the Chairman of the Board as well as Chief Executive Officer, the Board has designated one of its members to serve as a Lead Independent Director (“Lead Independent Director”). Dilip S. Vyas was appointed Lead Independent Director by all the Directors in September, 2011, and he continues to serve as Lead Independent Director. Mr. Vyas’ responsibilities include the following roles:

The Company believes that it maintains strong corporate governance processes intended to ensure that its independent Directors will continue to effectively monitor management and provide leadership on key issues such as strategy, risk and integrity. The Board has primary responsibility for the oversight of risks to the Company and has assigned to its committees the oversight of risks applicable to their particular area. Each committee of the Board is comprised solely of independent Directors. Consequently, independent Directors oversee such critical matters as the integrity of financial statements; the compensation of Executive Officers, including the Chief Executive Officer; financial commitments for capital projects; the selection and evaluation of Directors and Executive Officers; and the development and implementation of corporate governance programs. Each Board committee and the independent Directors as a group routinely have independent sessions without management present.

Management, the Company’s Corporate Counsel, and the Board of Directors discuss risks, both during and outside of Board meetings. These discussions identify Company risks which are prioritized and assigned to the appropriate Board committee or the full Board for oversight. Internal control and financial risks are overseen by the Audit Committee; compensation risks are overseen by the Compensation Committee; Chief Executive Officer succession planning is overseen by the Nominating Committee and reviewed by the independent Directors; compliance risks are typically referred to the full Board; and matters arising under the Company’s Code of Conduct or Code of Ethics for Senior Financial Management are handled by Corporate Counsel. Management regularly reports on each risk to the relevant committee or the Board, and material risks identified by a relevant committee are then presented to the full Board. The Company’s risk management program as a whole is reviewed annually at a meeting of the Board. Additional review or reporting on Company risks is conducted as needed or as requested by the Board or Committee. Coordination of management’s review of these risks is performed by the Company’s Corporate Counsel.

Stockholder Communications with the Board of Directors

Stockholders can contact the Board of Directors or any of the individual Directors by contacting: Henry J. Underwood, Corporate Counsel, Howard & Howard Attorneys PLLC, by regular mail at 200 South Michigan Avenue, Suite 1100, Chicago, IL 60604. Inquiries will be reviewed, sorted and summarized by the Corporate Counsel before they will be forwarded to the Board of Directors or to an individual Director.

EXECUTIVE COMPENSATION

The Employee Plan:

On July 9, 2015,June 2, 2016, the Board of Directors adopted the SigmaTron International, Inc. Employee Bonus Plan for Fiscal Year 20162017 (“Employee Plan”) applicable to all U.S. payroll non-union employees of the Company (“Employee Participants”), all full-time employees of the Company with a corporate position of vice president or higher (“Officers”) and all employees designated by the Company as an executive officer pursuant to the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (“Executive Officers”).

The stated purpose of the Employee Plan is to align stockholder, employee and officer objectives, to motivate employees of the Company and to increase shareholderstockholder value. The Employee Plan is administered and interpreted by the Board and, in its entirety, is subject to amendment, suspension or termination by the Board.

Pursuant to the Employee Plan, a Bonus Pool, calculated as a percentage of Pre-Tax Income (as defined in the Employee Plan) pursuant to the scale set forth in the Employee Plan, was created. The Company’s Chief Executive Officer submitted to the Compensation Committee a recommendation (i) of target objectives for each Executive Officer and (ii) for a specified percentage or dollar allocation of the Bonus Pool for each Executive Officer and Officer, individually, and all of the Employee Participants, in the aggregate. The Compensation Committee reviewed such submissions for recommendation to the Board. Awards to Executive Officers under the Employee Plan were based, in part, on the Executive Officer achieving the Executive Officer’s specified target objectives and, in any event, were subject to the sole discretion of the Board. Awards to Employee Participants under the Employee Plan were contingent upon the Company being in compliance with all of the Company’s covenants under its primary credit facility (currently with Wells Fargo Bank, N.A.), or having obtained a waiver thereof, at the end of the Company’s 20162017 fiscal year.

At the end of fiscal year 2016,2017, the Company awarded bonuses pursuant to the Employee Plan discussed above. Bonuses earned in fiscal year 20162017 and paid to Named Executive Officers in fiscal year 20172018 are listed in the Summary Compensation Table on the following page.

SUMMARY COMPENSATION TABLE

The individuals listed in the following table are referred to as our “Named Executive Officers” throughout this proxy statement. The following table sets forth a summary of all compensation paid by the Company for its fiscal years ended April 30, 20162017 and 20152016 to the Company’s Named Executive Officers:

(4) Includes match and contributions to the Company’s 401(k) plan made by the Company.

Employment Contracts, Termination of Employment and Change of Control Agreements

The Company adopted an Amended and Restated Change-in-Control Severance Payment Plan on March 11, 2014 (the “CIC Plan”), which covers Named Executive Officers and certain other Officers of the Company (each a “CIC Participant”). Under the terms of the CIC Plan, each CIC Participant is entitled to the payment of severance pay in the event such CIC Participant’sParticipant��s employment with the Company is involuntarily terminated within twenty-four months of a change of control of the Company. The amount of severance pay to which a CIC Participant may be entitled under the CIC Plan is a function of the CIC Participant’s average income paid by the Company to such CIC Participant for five calendar years ending immediately prior to the Change-in-Control.

In general, for purposes of the CIC Plan, a change of control will be deemed to have occurred when (a) the acquisition by an entity, person or group of beneficial ownership, as that term is defined in Rule 13d-3 under the Securities Exchange Act of 1934, of more than 20% in the aggregate of the outstanding capital stock of the Company entitled to vote for the election of directors, (b) as a result of, or in connection with, any cash tender or exchange offer, merger or other business combination, sale of assets or contested election, or any combination of the foregoing transactions, the persons who are directors of the Company before the transaction shall cease to constitute a majority of the board or the board of directors of any successor to the Company, (c) the Company becomes a party to a merger, consolidation or share exchange in which either (i) the Company will not be the surviving company or (ii) the Company will be the surviving company and any outstanding shares of common

15

stock of the Company will be converted into shares of any other company (other than a reincorporation or the

15

establishment of a holding company involving no change of ownership of the Company) or other securities or cash or other property (excluding payments made solely for fractional shares), (d) more than 50% of the assets and business of the Company are sold, transferred or assigned to, or otherwise acquired by, any other unrelated entity or entities, or (e) all or substantially all of the assets and business of a CIC Participant’s operation are sold, transferred or assigned to, or otherwise acquired by, any other unrelated entity or entities (“Change-in-Control”). In general, a CIC Participant’s employment will be deemed to have been involuntarily terminated under the CIC Plan in the event of such employee’s termination by the Company for a reason other than (w) for cause (as defined in the Plan), (x) death, (y) disability, or (z) that employee’s voluntary retirement or resignation except on account of the reasons set forth in the CIC Plan (which in general would result in a constructive discharge).

The CIC Plan provides for automatic reduction of the amounts to be paid out under the CIC Plan in the event such amounts would constitute “parachute payments” under the Internal Revenue Code. Disputes concerning the CIC Plan and benefits under the CIC Plan are subject to arbitration.

Potential Severance Payments upon Change-In-Control

The following table describes approximate potential severance payments under the CIC Plan to which the Named Executive Officers would be entitled upon Change-In-Control of the Company, assuming that the Change-In-Control of the Company occurred on April 30, 20162017 and all participants actually participated in the severance payment. The actual amount of payments can only be determined at the time of a Change-In-Control and will vary from the estimated amounts in the table below.

OUTSTANDING EQUITY AWARDS AT FISCAL YEAR END TABLE

The following table sets forth certain information with respect to each Named Executive Officer of the Company concerning any unexercised options held as of the end of fiscal year 2016.2017.

DEFINED CONTRIBUTION PLAN

The Company has established a tax-qualified defined contribution 401(k) retirement plan for U.S. employees, which includes Officers. The 401(k) Plan provides for Company matching of employee contributions up to $300 per employee per year and the Company has historically made a plan contribution of 1% of an employee’s compensation.

On February 1, 2014, the Company implemented the 2013 Employee Stock Purchase Plan (“ESPP”) which was approved by the stockholders at the Company’s 2013 Annual Meeting of Stockholders. Under the ESPP, all

16

eligible employees may purchase shares of the Company’s common stock at three-month intervals at 85% of the

16

lower of the fair market value of the Company’s common stock on the first day or the last day of the offering period (calculated in the manner provided in the ESPP). Eligible participating employees purchase such stock using payroll deductions, which may not be less than 1% nor exceed 15% of their total cash compensation per year.

The plan imposes certain limitations upon an employee’s right to acquire common stock, including the following: (i) termination of employment for any reason immediately terminates the employee’s participation in the plan, (ii) no employee may be granted rights to purchase more than $25,000 worth of common stock for any calendar year that such rights are at any time outstanding, and (iii) the maximum number of shares of common stock purchasable in total by all participants in the ESPP on any purchase date is limited to 500,000 shares. The number of shares of common stock reserved for issuance under the plan automatically increases on the first day of the Company’s fiscal year by 25,000 shares. During fiscal year 2016, 9,6702017, 1,658 shares were issued under the ESPP and the Company recorded $13,728$3,559 in compensation expense. The ESPP was terminated on August 15, 2016.

On September 20, 2013, the Company implemented the 2013 Non-Employee Director Restricted Stock Plan (“Director Plan”), approved by the stockholders at the 2013 Annual Meeting of the Stockholders. The purpose of the Director Plan is to promote the success and interest of the Company and to enhance the stock ownership of the Directors by providing a method whereby non-employee Directors may receive a portion of their annual compensation in restricted shares of the common stock of the Company. Pursuant to the Director Plan, non-

17

employeenon-employee Directors may be paid a portion of the annual compensation in an award of shares of restricted Common Stock of the Company (“Award”).

17

The Director Plan is administered by the Compensation Committee which has the power to determine the terms and provision of each Award. An aggregate of 50,000 shares of Common Stock of the Company were reserved for Awards under the Director Plan. Generally, stock awarded under the Director Plan does not vest until the six-month anniversary of the date of the Award and all shares of awarded restricted stock may not be sold, transferred or otherwise disposed of until they become vested, although the right to receive dividends with respect to the shares and to vote the shares occur upon grant. The Compensation Committee may amend, alter or terminate the Director Plan, subject to stockholder approval, if required.

3.    ADVISORY VOTE ON APPROVAL OF EXECUTIVE COMPENSATION

(“SAY-ON-PAY PROPOSAL”)

Pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”) and Section 14A of the Exchange Act, the Company is seeking stockholder approval, on an advisory, non-binding basis, for the compensation of the Company’s Named Executive Officers (“Say-on-Pay Proposal”). This Say-on-Pay Proposal gives stockholders the opportunity to express their views on the Company’s compensation of its Named Executive Officers disclosed in the executive compensation tables and Executive Compensation Section of this proxy statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Named Executive Officers. The timing of future votes will be determined by the Board, but will occur no less frequently than every three years.

The Company’s compensation programs for Executive Officers are designed to attract, motivate and retain talented executives who are critical to the success of the Company. The Compensation Committee reviews and recommends to the Board of Directors compensation paid or awarded to the Company’s Executive Officers. The Company is requesting its stockholders to indicate their support for compensation of its Named Executive Officers by approving the following resolution:

“RESOLVED, that the stockholders of SigmaTron International, Inc. approve the compensation of the Company’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K, in the executive compensation tables and related narrative discussion set forth in the Company’s 20162017 Proxy Statement.”

Assuming that a quorum is present, the non-binding, advisory resolution requires an affirmative vote by holders of a majority of the shares present at the Meeting in person or by proxy and entitled to vote on the matter.

Because your vote is advisory, it will not be binding upon the Board of Directors and may not be construed as overruling a decision or creating or implying any change to the fiduciary duties of the Board of Directors. However, the Board of Directors values the opinions of the Company’s stockholders and will consider the outcome of the vote when reviewing and recommending future executive compensation arrangements.

The Board of Directors unanimously recommends that you vote “For” the resolution approving the Company’s compensation for its Named Executive Officers.

4.    ADVISORY VOTE ON THE FREQUENCY OF HOLDING AN ADVISORY

VOTE ON THE SAY-ON-PAY PROPOSAL

Pursuant to the Dodd-Frank Act and Section 14A of the Exchange Act, the Company is seeking stockholder recommendation, on an advisory, non-binding basis, regarding the frequency of holding stockholder advisory votes on the Say-on-Pay Proposal. In particular, the stockholders are asked to vote on whether a Say-on-Pay Proposal advisory vote should occur every year, every two years, or every three years or to abstain. The Board will seek this vote in future years no less frequently than once every six calendar years.

Currently,As a result of the Company holdsadvisory vote of the stockholders at the 2016 Annual Stockholders Meeting, the Board of Directors decided to hold at this year’s Annual Stockholders Meeting an advisory vote on the compensation of the Company’s Named Executive Officers every three years.Officers. The Board of Directors believes that an advisory vote every three years on the Say-on-

18

PaySay-on-Pay Proposal would be most appropriate for the Company. This would give Company’s

18

stockholders sufficient opportunity to react to emerging trends in executive compensation. In addition, a triennial vote would provide the Compensation Committee and Board of Directors the time to thoughtfully evaluate stockholder reactions and implement any necessary changes to the executive compensation program and compensation decisions. The Company is requesting its stockholders to provide an advisory vote on the following resolution:

“RESOLVED, that the stockholders of SigmaTron International, Inc. advise the Company to include a non-binding, advisory vote on the compensation of the Company’s Named Executive Officers pursuant to Section 14A of the Securities Exchange Act of 1934, as amended, every:

Assuming that a quorum is present, the non-binding, advisory recommendation of the shareholdersstockholders for the frequency of holding future advisory votes on executive compensation will be that choice which receives a plurality of the votes cast.

Because your vote is advisory, it will not be binding on the Board of Directors and may not be construed as overruling a decision by or creating or implying any change to the fiduciary duties of the Board of Directors. However, the Compensation Committee and the Board of Directors value stockholder opinions and will consider the voting results when determining the frequency of future advisory votes on executive compensation.

The Board of Directors unanimously recommends that stockholders select “three years” on the proposal recommending the frequency of advisory votes on executive compensation.
