20182019 ANNUAL MEETING OF STOCKHOLDERS

September 21, 201813, 2019

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 20182019 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 21, 2018,13, 2019, 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, 2018,2019, are being mailed to stockholders on or about August 17, 2018.16, 2019.

Stockholders of record at the close of business on July 27, 2018,26, 2019, are entitled to notice of and to vote at the Meeting. On such date, there were outstanding 4,230,0084,242,508 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 27, 2018)26, 2019), 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 on their behalf. (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 at847-956-8000.

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) proposal related to the SigmaTron International, Inc. 2019 Employee Stock Option Plan, (iii) the proposal related to the advisory approval on the compensation of the Company’s Named Executive Officers, and (iii)(iv) the proposal related to the advisory approval regarding the recommendation to select a 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 (“BrokerNon-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 proxiesproxy cards 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 threetwo Class III 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 adoption of the 2019 Employee Stock Option Plan, (iv) FOR the advisory vote on the approval of the compensation of the Company’s Named Executive Officers and (iv)(v) FOR a three-year frequency of advisory votes on executive compensation. If a

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 2019.2020.

In connection with the audits for the years ended April 30, 20182019 and 2017,2018, 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 20182019 and 2017.2018.

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. BrokerNon-Votes, while considered present at a meeting and included in the determination of whether a quorum exists, are not considered entitled to vote. Thus, BrokerNon-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, 2019.2020.

3.    PROPOSAL TO APPROVE THE 2019 EMPLOYEE STOCK OPTION PLAN

On May 30, 2019, the Board of Directors of the Company adopted, subject to stockholder approval, the SigmaTron International, Inc. 2019 Employee Stock Option Plan (the “2019 Employee Plan”). The purpose of the 2019 Employee Plan is to permit the Company and its subsidiaries to attract and retain as employees individuals of initiative and ability and to provide additional employee incentives to existing employees.

On July 26, 2019, the last reported sale price of the Company’s Common Stock on the NasdaqSmall-Cap Market, on which the Company’s stock is listed, was $4.95 per share.

Summary of 2019 Employee Plan

The 2019 Employee Plan will be construed, interpreted and administered by the Compensation Committee (“the Committee”). The Committee has the discretion to determine the individuals to whom options are granted, the number of shares subject to the options, the exercise price of the options (but in no event less than the minimum required in order to comply with applicable law), the period over which the options become exercisable, the term of the options (including the period after termination of employment during which an option may be exercised) and certain other provisions related to the options. Individuals who are selected to receive options will sign an option agreement with the Company setting forth the terms and restrictions applicable to their options.

Under the 2019 Employee Plan, the Committee may grant options for an aggregate maximum of 150,000 shares of the Company’s Common Stock to employees of the Company and its subsidiaries, including the Company’s executive officers. The number of shares available for the grant of options under the Plan and the number of shares included in each outstanding option are subject to adjustment upon recapitalizations, stock splits or other similar events that cause changes in the Company’s Common Stock. The Company must retain sufficient authorized but unissued shares of Common Stock to assure itself of its ability to perform its obligations under the 2019 Employee Plan. Shares of Common Stock underlying options that expire unexercised will be available for future option grants under the Plan.

The 2019 Employee Plan provides for the grant of incentive stock options (“Incentive Options”) within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), andnon-statutory stock options that do not qualify as Incentive Options.

The option exercise price per share for each option granted under the 2019 Employee Plan shall be not less than the closing price of the Common Stock on the NasdaqSmall-Cap Market on the trading day immediately preceding the date of grant. An option may be exercised by the payment of the exercise price (i) in cash or by check, (ii) through the exchange of shares of Common Stock already owned by the optionee having a fair market value equal to the exercise price, (iii) through a broker-assisted “cashless” exercise transaction, through a broker selected by the employee without assistance of the Company in arranging such transaction, or (iv) by any other payment means approved by the Committee.

The maximum term of any options granted under the 2019 Employee Plan is ten years. Subject to that limitation, the Committee has discretion to decide the period over which options may be vested and exercised. In addition, unvested options will terminate immediately upon termination of employment, disability or death. All outstanding options granted under the 2019 Employee Plan shall immediately become exercisable in full upon a Corporate Transaction (as defined in the Plan and generally covering a sale of the Company) provided that the Corporate Transaction closes. Any options not exercised within that period expire.

An optionee may exercise aNon-Statutory Option that has vested if the optionee has been employed by the Company continuously since the date the option was granted. If an optionee’s employment is terminated for cause (as defined in the 2019 Employee Plan), the optionee has three months (or the remainder of the original term of the exercise period, whichever is shorter) to exercise anyNon-Statutory Options vested as of the date of termination; all unvestedNon-Statutory Options expire. If an optionee’s employment is terminated for a reason other than for cause, including voluntary termination, death or disability, all unvestedNon-Statutory Options expire while all vestedNon-Statutory Options may be exercised for the remainder of their terms. The same

11

provisions apply to Incentive Options except that an optionee whose employment is terminated must exercise vested Incentive Options within three months after the date of termination or the expiration of the original exercise period, whichever is shorter.

Except as otherwise provided in the applicable option agreement, all options granted under the 2019 Employee Plan shall not be transferable unless (a) the transfer is (i) by will or the laws of descent and distribution, (ii) pursuant to a qualified domestic relations order, (iii) to a Permitted Transferee, (as defined in the 2019 Employee Plan), or (iv) to a trust or other entity controlled by the optionee or a Family Member (as defined in the 2019 Employee Plan; generally family members or trusts or other entities controlled by the optionee or a family member); (b) the transfer is a gift; and (c) the option continues to be subject to the same terms as before the transfer.

The Committee is authorized to condition the grant of options upon the receipt of the agreement by the optionee not to compete with the Company during the term of employment and for such period thereafter and containing such other terms as are determined by the Committee.

No options have been granted under the 2019 Employee Plan.

Income Tax Consequences

Generally, for federal income tax purposes,Non-Statutory Options will not result in any taxable income to the optionee at the time of grant. The optionee will realize ordinary income, however, at the time of the exercise of the option, in an amount measured by the excess of the fair market value of the optioned shares at the time of exercise over the option exercise price, regardless of whether the exercise price is paid in cash or shares.

Where ordinary income is recognized in connection with the exercise of an option, the Company will be entitled to a deduction in the amount of ordinary income so recognized, provided, among other things, that the Company complies with applicable tax withholding requirements.

No income is recognized for federal income tax purposes when an Incentive Option is exercised and no deduction is available to the Company. Incentive Options will be taxed asNon-Statutory Options if shares of Common Stock purchased upon exercise of the Incentive Option are sold within one year after the exercise or two years after the date the Incentive Option is granted.

The Board of Directors recommends that the stockholders vote FOR the adoption of the 2019 Employee Plan.

The adoption of the 2019 Employee Plan 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. BrokerNon-Votes, while considered present at a meeting and included in the determination of whether a quorum exists, are not entitled to vote. Thus, BrokerNon-Votes will have no effect. Abstentions will have the same effect as negative votes. The 2019 Employee Stock Option Plan is included in this Proxy Statement under the heading Appendix A.

CORPORATE GOVERNANCE

Our Board of Directors determined that each of Messrs. Horek, Mantia, Plante, Rieck and Vyas are independent under the rules of Nasdaq. Accordingly, 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 to 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 RegulationS-K promulgated under the Exchange Act. The Board of Directors has adopted a written charter for the Audit Committee, which was revised and restated on May 22, 2018,30, 2019, and is available on the Company’s website atwww.sigmatronintl.com. The reportCharter of the Audit Committee to the Stockholders is included in this Proxy Statement under the heading Appendix A.B.

The functions of the Compensation Committee are: (1) to review and recommend to the Board of Directors annual salaries and bonuses for all Executive Officers of the Company; (2) to review and recommend to the Board of Directors compensation for the Directors; (3) to review and recommend to the Board of Directors the terms and conditions of all employee benefit plans or changes thereto; and (4) 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

1113

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,Board; the Company’s operating requirements, and the long-term interests of the Company’s 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 all 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’sby-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 1812 meetings either in person or by telephone conference during the fiscal year ended April 30, 2018.2019. The Compensation Committee held 45 meetings in person or by telephone conference and the Audit Committee held 911 meetings in person or by telephone conference during the fiscal year 2018.2019. The Nominating Committee held 1 meeting during the fiscal year 2018.2019. All Directors attended at least 75% of the

12

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 20172018 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 andin-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.

Underwood, Corporate Counsel, Howard & Howard Attorneys PLLC, by regular mail at 200 South Michigan Avenue, Suite 1100, Chicago, IL 60604.

EXECUTIVE COMPENSATION

The Employee Plan:

On April 21, 2017,July 12, 2018, the Board of Directors adopted the SigmaTron International, Inc. Employee Bonus Plan for Fiscal Year 20182019 (“Employee Plan”) applicable to all U.S. payrollnon-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 stockholder 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 ofPre-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 or having obtained a waiver thereof, at the end of the Company’s 20182019 fiscal year.

At the end of fiscal year 2018,2019, the Company awarded no bonuses pursuant to the Employee Plan discussed above.

On May 22, 2018, the Compensation Committee recommended to the Board of Directors that the Company reserve a special bonus pool of $352,516 available for grant to employees at the time salaries and bonuses for the 12 months commencing July 1, 2018 are reviewed. Subsequently, the Board of Directors adopted the Compensation Committee’s recommendation but delayed any grants from the special bonus pool until after the Annual Stockholders Meeting to be held on September 21, 2018.

The following table sets forth a summary of all compensation paid by the Company for its fiscal years ended April 30, 20182019 and 20172018 to the Company’s Named Executive Officers:

Employment Contracts, Termination of Employment and Change of Control Agreements

The Company adopted an Amended and RestatedChange-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’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 theChange-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 Rule13d-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 stock of the Company will be converted into shares of any other company (other than a reincorporation or the

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 uponChange-In-Control

The following table describes approximate potential severance payments under the CIC Plan to which the Named Executive Officers would be entitled uponChange-In-Control of the Company, assuming that theChange-In-Control of the Company occurred on April 30, 20182019 and all participants actually participated in the severance payment. The actual amount of payments can only be determined at the time of aChange-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 2018.2019.

EQUITY AWARDS GRANTED IN FISCAL YEAR 2019

DEFINED CONTRIBUTION PLAN

The Company has established atax-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 eligible employees were entitled to purchase shares of the Company’s common stock at three-month intervals at

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 RegulationS-K, in the executive compensation tables and related narrative discussion set forth in the Company’s 20182019 Proxy Statement.”

Assuming that a quorum is present, thenon-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.

5.    ADVISORY VOTE ON THE FREQUENCY OF HOLDING AN ADVISORY

VOTE ON THESAY-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 theSay-on-Pay Proposal. In particular, the stockholders are asked to vote on whether aSay-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.

As a result of the advisory vote of the stockholders at the 2017 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. The Board of Directors believes that an advisory vote every three years on theSay-on-Pay Proposal would be most appropriate for the Company. This would give Company’s 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 anon-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:

Subject to the conditions of, and within the limitations prescribed in, Paragraph 12, the Committee may cancel, modify, extend or renew outstanding Options, provided, however, that no such action shall reduce the Option Price to an amount less than the Fair Market Value of Shares subject to the Option on the date of grant and provided further that no such action shall cause any feature for the deferral of compensation as such term is defined under Treas.

All Options shall meet the requirements of this Paragraph 6, provided, however, that only ISO’s are subject to Subparagraphs 6(b) and 6(f)(i) and only NSO’s are subject to Subparagraphs 6(d) and 6(f)(ii).

(ii) Subject to Subparagraphs 6(b)(i) and 6(c), ISOs granted under the Plan shall continue in effect for the period fixed by the Committee, except than no ISO shall be exercisable after the expiration of ten (10) years from the date it is granted.

(iii) The Option Price per Share shall be determined by the Committee at the time of grant. Subject to Subparagraph 6(b)(i), the Option Price shall not be less than 100 percent of the Fair Market Value of the Shares subject to the ISO on the date the Option is granted.

(iv) No ISO shall be granted on or after the tenth anniversary of the Effective Date of the Plan.

(v) No ISO shall provide any person with a right to purchase Shares to the extent that such right first becomes exercisable during a prescribed calendar year and the sum of (A) the Fair Market Value (determined as of the date of grant) of the Shares subject to such ISO which first become available for purchase during such calendar year plus (B) the Fair Market Value (determined as of the date of grant) of all Shares subject to ISOs previously granted to such person under all plans of the Company first become available for purchase during such calendar year exceeds $100,000. If the Code is amended to provide for a different limitation from that set forth in this Subparagraph, such different limitation shall be deemed incorporated herein effective as of the effective date of such amendment and with respect to such Options as required or permitted by such amendment to the Code.

(vi) Without written notice to the Committee, an Optionee may not dispose of Shares acquired pursuant to the exercise of an ISO until after the later of (A) the second anniversary of the date on which the ISO was granted, or (B) the first anniversary of the date on which the Shares were acquired. An Optionee shall make appropriate arrangements with the Company for any taxes which the Company is obligated to collect in connection with any disposition of Shares acquired pursuant to the exercise of an ISO, including any federal, state or local withholding taxes.

(vii) Should Section 422 of the Code be amended during the term of the Plan, the Committee may modify the Plan consistently with such amendment.

(viii) An ISO granted under this Plan is not transferable by the Optionee except by will or the laws of descent and distribution and, during the lifetime of the Optionee, an ISO is exercisable only by the Optionee.

(c) Exercise of Options. Except as provided in Subparagraph 6(f), no Option granted under the Plan to an employee may be exercised unless at the time of such exercise the Optionee is employed by the Company and shall have been so employed continuously since the date such Option was granted. Absence on leave or on account of illness or disability under rules established by the Committee shall not, however, be deemed an interruption of employment for this purpose. Except as provided in this Subparagraph and Subparagraphs 6(f), 7 and 8, Options granted under the Plan may be exercised from time to time over the period stated in each Option in such amounts and at such times as shall be prescribed by the Committee, provided that Options shall not be exercised for fractional shares, and the election to exercise an Option shall be made in accordance with applicable federal and state laws and regulations. Unless otherwise determined by the Committee, if the Optionee does not exercise an Option in any one year with respect to the full number of Shares to which the Optionee is entitled in that year, the Optionee’s rights shall be cumulative and the Optionee may purchase those Shares in any subsequent year during the term of the Option. No Option shall be exercisable after the expiration of ten (10) years from the date it is granted.

27

(d) Transferability. The Committee shall retain the authority and discretion to permit an NSO to be transferable as long as such transfers are made only to a Permitted Transferee; provided that (i) such transfer is a bona fide gift and accordingly, the Optionee receives no value for the transfer, as provided in the instructions to SEC FormS-8, (ii) that the NSOs transferred continue to be subject to the same terms and conditions that were applicable to the NSOs immediately prior to the transfer, and (iii) that the NSOs may not be otherwise or subsequently sold, pledged, assigned or transferred in any manner except by will or the laws of descent or distribution or pursuant to a domestic relations order. In the event of the Optionee’s death, the NSO may be exercised only by a person who acquired the right to exercise it by reason of the death of the Optionee. Neither the Optionee, any Permitted Transferee, nor any person who acquires the right to exercise the NSO by reason of the death of the Optionee will be deemed to be a holder of any Shares subject to the NSO unless and until certificates for those Shares are issued to such person. A Permitted Transferee may not subsequently transfer an NSO. The designation of a beneficiary shall not constitute a transfer.

(e) Vesting. Options granted under the Plan shall vest according to such schedule as the Committee may prescribe at the time of grant, which may include full and immediate vesting.

(f) Termination of Employment or Death.

(i) With respect to ISOs:

(A) If the employment of an employee is terminated for any reason other than Disability or death, any then outstanding Options held by such employee to the extent vested at termination of employment shall be exercisable, in accordance with the provisions of the Option agreement, by such employee at any time prior to the expiration date of such Option or within three (3) months after the date of termination of employment, whichever is the shorter period.

(B) Unless the Committee determines otherwise, if the employee’s employment is terminated because of a Disability, any then outstanding Options held by such employee to the extent vested at termination of employment shall be exercisable, in accordance with the provisions of the Option Agreement, by such employee at any time prior to the expiration date of such Option or within one year after the date of termination of employment, whichever is the shorter period.

(C) If the employee dies while employed by the Company, any then outstanding Options held by such employee to the extent vested on the date of death shall be exercisable, in accordance with the provisions of the Option Agreement, by the duly appointed representative of the employee’s estate at any time prior to the expiration date of such Option or within one year after the date of death, whichever is the shorter period.

(D) If a termination under Subparagraph 6(f)(i)(B) or (C) occurs, any unvested portion of the Option held by the employee shall become vested, provided that the aggregate value of Shares with respect to which any ISO first becomes exercisable in the calendar year of the termination of employment does not exceed $100,000. If the value of Shares which become fully vested under an ISO exceed $100,000, such excess shall be treated as stock subject to an NSO. For purposes of the $100,000 limitation, the Fair Market Value of the Shares on the date the ISO was granted shall be used in determining the value of the Shares. If the Code is amended to provide for a limitation different from the one set forth in this Paragraph, such different limitation shall be deemed incorporated herein effective as of the effective date of such amendment and with respect to such Options as required or permitted by such amendment to the Code.

(ii) With respect to NSOs:

(A) If the employment of an Optionee is terminated For Cause, then the unvested portion of any then outstanding Options held by such Optionee shall be immediately canceled and the unexercised vested portion of any then outstanding Options held by such Optionee shall be exercisable (to the extent then exercisable in accordance with the provisions of the Option Agreement), by the Optionee or Permitted Transferee at any time prior to the expiration date or within three months after the date of termination of employment, whichever is the shorter period.

(B) If the employment of an Optionee is terminated by the Company, but such termination is not For Cause, then the unvested portion of any then outstanding Options held by such Optionee shall be

28

immediately canceled and the vested portion of any then outstanding Options held by such Optionee shall continue in effect after the Optionee’s termination of employment under the terms of the Option Agreement. This Subparagraph shall also apply to an Optionee who voluntarily terminates employment with the Company.

(C) If the employment of Optionee is terminated because of the death or Disability, then the unvested portion of any then outstanding Options held by such Optionee shall be immediately vested and the unexercised vested portion of any then outstanding Options held by such Optionee at the time of death or Disability shall be exercisable in full (including the portion which, but for this provision, would not be exercisable), by the Optionee, the Permitted Transferee or if the Optionee is deceased, by the person or persons entitled to do so under the will of the Optionee, or if the Optionee shall fail to make testamentary disposition of the Option or shall die intestate, by the legal representative of the Optionee, at any time prior to the expiration date of such Option.

(iii) For all Options issued hereunder, to the extent that the Option of any deceased Optionee or any Optionee whose employment terminates is not exercised within the applicable period, all further rights to purchase Shares pursuant to such Option shall cease and terminate.

(g) Purchase of Shares. Unless the Committee determines otherwise, Shares may be acquired pursuant to an Option granted under the Plan only upon receipt by the Company of notice in writing from the Optionee of the Optionee’s intention to exercise, specifying the number of Options the Optionee desires to exercise and the date on which the Optionee desires to complete the transaction, and such other documentation as may be required by the Company. Unless the Committee determines otherwise, on or before the date specified for completion of the purchase of Shares pursuant to an Option, the Optionee must have paid the Company the full purchase price of such Shares in cash or by check, or, with the consent of the Committee, in whole or in part, by a cashless exercise as described below. The Optionee may tender Shares only if the Optionee has not acquired any Shares (including the Shares being tendered), other than in an acquisition exempt from Section 16(b) of the 1934 Act and rules and regulations promulgated thereunder, for a period of at least six months prior to the tender. The value of the Shares provided in payment of the Option Price shall be deemed to be the Fair Market Value of the Shares on the date of exercise of the Option. No Shares shall be issued until full payment therefor has been made. No Shares shall be delivered pursuant to the exercise of any Option, in whole or in part, until the Shares are qualified for delivery under such securities laws and regulations as may be deemed by the Committee to be applicable thereto, and such Shares are listed on each securities exchange on which Shares may then be listed. If the Company is required to withhold on account of any present or future tax imposed as a result of an exercise, the Committee shall have the sole discretion to determine whether such withholding shall be satisfied by a cash payment from Optionee or by withholding Shares having a Fair Market Value equal to the amount of the required withholding. (The value of shares shall be determined using the Fair Market Value of the Shares on the date the amount of withholding is determined.) However, no such withholding of Shares shall occur until the Company has been subject to the requirements of Section 13(a) of the 1934 Act for at least one year prior to the exercise of the Option, and the Company regularly releases its quarterly and annual summary statements of sales and earnings for publication. An exercise may, if permitted under applicable law, include a cashless exercise if the Options are tendered to a securities broker selected by an Optionee, and pursuant to an arrangement between the Optionee and such broker, the Options are exchanged for the number of Shares the Fair Market Value of which is equal to the aggregate difference between the Option Price and the Fair Market Value of the Options so tendered.

7.Changes in Capital Structure. If any change is made in the Shares subject to the Plan or subject to the Options granted under the Plan (through reorganization, merger, consolidation, plan of exchange, recapitalization, reclassification, stock split, combination of shares or dividend payable in Shares or otherwise), adjustments as it deems appropriate shall be made by the Committee in the number and kind of Shares available for awards under the Plan, provided that this Paragraph 7 shall not apply with respect to transactions referred to in Paragraph 8. In addition, the Committee shall make such adjustments as it deems appropriate in the number and kind of Shares as to which outstanding Options, or portions thereof then unexercised, shall be exercisable and/or the Option price, to the end that the Optionee’s proportionate interest is maintained as before the occurrence of such event. The Committee may also require that any securities issued in respect of or in exchange

29

for Shares issued hereunder that are subject to restrictions be subject to similar restrictions. Notwithstanding the foregoing, the Committee shall have no obligation to effect any adjustment that would or might result in the issuance of fractional shares, and any fractional shares resulting from any adjustment may be disregarded or provided for in any manner determined by the Committee. Any such adjustments made by the Committee shall be conclusive. Any such adjustments shall be made in such a manner so as to avoid application of Code Section 409A to any affected Option(s) or the Plan.

8. Special Acceleration in Certain Events.

(a) Notwithstanding any other provisions of the Plan, upon the occurrence of a Corporate Transaction, all Options shall vest and become fully exercisable as to all of the Shares subject to the Options as of the date thirty (30) days prior to the date of the Corporate Transaction. The exercise or vesting of any Option and any Shares acquired upon the exercise thereof that was permissible solely by reason of this Paragraph 8 shall be conditioned upon the consummation of the Corporate Transaction. Any Options that are not exercised as of the date of the Corporate Transaction shall terminate and cease to be outstanding effective as of the date of the Corporate Transaction.

(b) Other than upon the occurrence of a Corporate Transaction, the Committee shall have the authority at any time or from time to time to accelerate the vesting of any individual Option and to permit any Option not theretofore exercisable to become immediately exercisable.

(c) Accelerated vesting under this Paragraph shall be limited to the maximum number of additional Shares such that the acquisition or disposition of such Shares which vest in connection with a Corporate Transaction shall not result in an excess parachute payment to an Optionee (as defined in Section 280G of the Code), unless the Committee authorizes accelerated vesting in excess of such maximum amount. The Company may collect from an Optionee any additional income or excise taxes which the Company may incur as a result of such authorization or a violation of this provision

9.Corporate Mergers, Acquisitions, Etc.The Committee may also grant Options under the Plan having terms, conditions and provisions that vary from those specified in the Plan, provided that any such awards are granted in substitution for, or in connection with the assumption of, existing Options, issued by another corporation and assumed or otherwise agreed to be provided for by the Company pursuant to or by reason of a transaction involving a corporate merger, consolidation, plan of exchange, acquisition of property or stock, separation, reorganization or liquidation to which the Company is a party.

10.Administration with Respect to Insiders.With respect to the participation of Insiders in the Plan, at any time that any class of equity security of the Company is registered pursuant to Section 12 of the 1934 Act, the Plan shall be administered in compliance with the requirements, if any, of Rule16b-3.

11.Indemnification.In addition to such other rights of indemnification as they may have as members of the Board of Directors or officers or employees of the Company, any director, officer or employee of the Company to whom authority to act for the Board or the Company is delegated shall be indemnified by the Company against all reasonable expenses, including attorneys’ fees, actually and necessarily incurred in connection with the defense of any action, suit or proceeding, or in connection with any appeal thereof, to which they or any of them may be a party by reason of any action taken or failure to act under or in connection with the Plan, or any right granted hereunder, and against all amounts paid by them in settlement thereof (provided such settlement is approved by independent legal counsel selected by the Company) or paid by them in satisfaction of a judgment in any such action, suit or proceeding, except in relation to matters as to which it shall be adjudged in such action, suit or proceeding that such person is liable for gross negligence, bad faith or intentional misconduct in duties; provided, however, that within sixty (60) days after the institution of such action, suit or proceeding, such person shall offer to the Company, in writing, the opportunity at the Company’s own expense to handle and defend same.

12.Amendment or Termination of Plan.The Board of Directors at any time, and from time to time, may amend or terminate the Plan in such respects as it shall deem advisable because of changes in the law while the Plan is in effect or for any other reason, provided, however, that no such amendment shall reduce the Option

30

Price to an amount less than the Fair Market Value of Shares subject to the Option on the date of grant. Except as provided in Paragraphs 6(f), 7 and 8, however, no change in an award already granted shall be made without the written consent of the holder of such award (unless such termination or amendment is required to enable an Option designated as an ISO to qualify as an Incentive Stock Option or is necessary to comply with any applicable law, regulation or rule), and no amendment or termination shall be made which without the approval of the stockholders of the Company would cause the Plan to no longer comply with Rule16b-3 under the 1934 Act, Sections 162(m) or 422 of the Code or any other regulatory requirements. Notwithstanding the immediately foregoing, no amendment of the Plan which increases the aggregate number of Shares available under the Plan except to reflect events described in Paragraph 7 hereof, changes the class of employees eligible to participate in the Plan, extends the term of the Plan, or reduces the minimum permissible exercise price of an Option under the Plan that is approved by the Board of Directors shall be effective unless, within 12 months of the date of adoption of such amendment, the amendment is approved by the stockholders of the Company.

13.Approvals. The obligations of the Company under the Plan are subject to the approval of state and federal authorities or agencies with jurisdiction in the matter. The Company will use its best efforts to take steps required by state or federal law or applicable regulations, including rules and regulations of the Securities and Exchange Commission and any stock exchange or trading system on which the Company’s shares may then be listed or admitted for trading, in connection with grants under the Plan. The foregoing notwithstanding, the Company shall not be obligated to issue or deliver Options or Shares under the Plan if such issuance or delivery would violate applicable state or federal securities law, or any other state or federal law or regulation.

14.Employment Rights.Nothing in the Plan or any award pursuant to the Plan shall confer upon any employee any right to be continued in the employment of the Company or shall interfere in any way with the right of the Company to terminate an employee’s employment at any time, for any reason, with or without cause, or to increase or decrease an employee’s compensation or benefits or to alter the terms of employment.

15.Rights as a Stockholder.The recipient of any award under the Plan shall have no rights as a stockholder with respect to any Shares until the date of issue to the recipient of a stock certificate for such Shares. Except as otherwise expressly provided in the Plan, no adjustment shall be made for dividends or other rights for which the record date is prior to the date such stock certificate is issued.

16.Governing Law. All questions arising with respect to the provisions of the Plan shall be determined by application of the laws of the state of Illinois except to the extent that Illinois laws are preempted by any federal statute, regulation, judgment or court order, including but not limited to, the Code.

17. Miscellaneous.

(a) Nothing contained in the Plan shall prevent the Board of Directors from adopting other or additional compensation arrangements, subject to stockholder approval if such approval is required; and such arrangements may be either generally applicable or applicable only in specific cases.

(b) The Committee shall condition any grant of any Option under the Plan upon the recipient’s execution and delivery to the Company of an agreement not to compete with the Company during the recipient’s employment with the Company and for such period thereafter as shall be determined by the Committee. Such covenant against competition shall be in a form satisfactory to the Committee.

(c) If any Option under this Plan is considered deferred compensation, as such term is defined under Section 409A of the Code (“Deferred Compensation”), the Committee reserves the right to unilaterally amend the Plan or an Option Agreement to the extent the Committee determines that such amendment is necessary to comply with Section 409A of the Code or to qualify for an exemption from Section 409A of the Code. A Participant’s acceptance of any award under the Plan constitutes acknowledgement and consent to such rights of the Committee, without further consideration or action. Any discretionary authority retained by the Committee pursuant to the terms of this Plan or an Option Agreement shall not be applicable to an award which is determined to constitute Deferred Compensation, if such discretionary authority would contravene Section 409A of the Code, including, by way of example and not limitation, discretion authority, the exercise of which would constitute an acceleration of payment or the change in the form or timing of payment of Deferred Compensation.

31

IN WITNESS WHEREOF, this Plan is executed this 13th day of September, 2019, to be effective as of the Effective Date.
