SigmaTron International, Inc.

at

$3.02 per share, net in cash, without interest and less any required tax withholding

by

Transom Axis MergerSub, Inc.

a wholly owned subsidiary

of

Transom Axis AcquireCo, LLC

Transom Axis MergerSub, Inc., a Delaware corporation (“Merger Sub”), and a wholly owned subsidiary of Transom Axis AcquireCo, LLC, a Delaware limited liability company (“Parent”), is offering to purchase all of the issued and outstanding shares of common stock, par value $0.01 per share (the “Shares”), of SigmaTron International, Inc., a Delaware corporation (“SigmaTron”), at a purchase price of $3.02 per Share (the “Offer Price”), net to the stockholder in cash, without interest and less any required tax withholding, upon the terms and subject to the conditions set forth in the Offer to Purchase and in the related Letter of Transmittal (which, together with the Offer to Purchase, as each may be amended or supplemented from time to time, collectively constitute the “Offer”).

Tendering stockholders who are holders of record of their Shares and who tender directly to Equiniti Trust Company, LLC, the depositary and paying agent for the Offer (the “Depositary”), will not be obligated to pay brokerage fees or commissions or, except as otherwise provided in Instruction 6 of the Letter of Transmittal, stock transfer taxes with respect to the purchase of Shares by Merger Sub pursuant to the Offer. Stockholders who hold their Shares through a broker, dealer, commercial bank, trust company or other nominee should consult such broker, dealer, commercial bank, trust company or other nominee as to whether it charges any service fees or commissions.

The Offer is being made pursuant to an Agreement and Plan of Merger, dated May 20, 2025 (as it may be amended from time to time, the “ Merger Agreement”), by and among SigmaTron, Parent and Merger Sub, pursuant to which, after consummation of the Offer and subject to the satisfaction or waiver of certain conditions, Merger Sub will merge with and into SigmaTron pursuant to Section 251(h) of the General Corporation Law of the State of Delaware, as amended (the “DGCL”), upon the terms and subject to the conditions set forth in the Merger Agreement, with SigmaTron continuing as the surviving corporation (the “Surviving Corporation”) and becoming a wholly owned subsidiary of Parent (the “Merger”). At the effective time of the Merger (the “Effective Time”), each Share issued and outstanding immediately prior to the Effective Time (other than (i) Shares owned by SigmaTron (as treasury stock or otherwise) immediately prior to the Effective Time, (ii) Shares directly owned by Parent or Merger Sub, and any Share that is owned by any wholly owned subsidiary of Parent (other than Merger Sub), in each case, immediately prior to the Effective Time, or (iii) Shares issued and outstanding immediately prior to the Effective Time and that are held by holders of such Shares who have not tendered their Shares and are entitled to and have properly exercised appraisal rights with respect thereto in accordance with, and who have complied with, Section 262 of the DGCL with respect to any such Shares held by any such holder (the “Dissenting Shares”), will be converted into the right to receive an amount in cash equal to the Offer Price, without interest, less any required tax withholding, from Merger Sub.

The Offer and the Merger are not subject to any financing condition. The obligation of Merger Sub to accept for payment and pay for Shares validly tendered (and not properly withdrawn) pursuant to the Offer is subject to the satisfaction of the conditions set forth in Section 15 of the Offer to Purchase (collectively, the “Offer Conditions”), including the Minimum Condition.

 The “Minimum Condition” means that there have been validly tendered in accordance with the terms of the Offer and “received” (as defined in Section 251(h)(6)(f) of the DGCL) and not validly withdrawn, a number of Shares that represents (and will represent immediately following the consummation of the Offer) at least a majority of the aggregate voting power of all Shares then outstanding.

The term “Expiration Date” means one minute past 11:59 P.M., Eastern Time, on July 24, 2025, unless the expiration of the Offer is extended to a subsequent date in accordance with the terms of the Merger Agreement, in which case the term “Expiration Date” means such subsequent time on such subsequent date. A subsequent offering period for the Offer is not contemplated.

The Board of Directors of SigmaTron (the “SigmaTron Board”) unanimously (i) determined that it is in the best interests of SigmaTron and its stockholders, and declared it advisable, for SigmaTron to enter into the Merger Agreement, (ii) approved the execution, delivery and performance of the Merger Agreement and the consummation of the transactions contemplated by the Merger Agreement, including the Offer and the Merger, (iii) resolved that the Merger shall be effected under Section 251(h) of the DGCL, and (iv) resolved to recommend that the stockholders of SigmaTron tender their Shares to Merger Sub pursuant to the Offer, all upon the terms and subject to the conditions set forth in the Merger Agreement.

Descriptions of the reasons for the SigmaTron Board’s recommendation and approval of the Offer are set forth in SigmaTron’s Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”), which is being mailed to SigmaTron stockholders together with the Offer materials (including the Offer to Purchase and the related Letter of Transmittal). Stockholders should carefully read the information set forth in the Schedule 14D-9, including the information set forth in Item 4 thereof under the sub-headings “Recommendation of the Board”, “Background of the Offer and the Merger” and “Reasons for the Recommendation.”

The Merger Agreement contains provisions that govern the circumstances under which Merger Sub is required or permitted to extend the Offer and under which Parent is required to cause Merger Sub to extend the Offer. Specifically, the Merger Agreement provides that: (i) Merger Sub shall extend the Offer for any period required by any rule, regulation, interpretation or position of the U.S. Securities and Exchange Commission (the “SEC”) or the staff thereof applicable to the Offer, the document governing the Offer or any period otherwise required by the rules and regulations of Nasdaq or applicable law (including in order to comply with Rule 14e-1(b) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) in respect of the Offer Price); (ii) if, as of the then-scheduled Expiration Date, any of the Offer Conditions (other than the Minimum Condition and any such conditions that by their nature are to be satisfied at the Expiration Date (provided, that such other Offer Conditions would be capable of being satisfied or validly waived were the Expiration Date to occur at such time)) is not satisfied (unless such other Offer Condition is waivable by Merger Sub or Parent and has been validly waived), Merger Sub shall extend the Offer and the Expiration Date for additional periods of up to ten (10) Business Days (calculated as set forth in Rule 14d-1(g)(3) under the Exchange Act) per extension; (iii) if, as of the then-scheduled Expiration Date, each of the Offer Conditions (other than the Minimum Condition, and other than any other Offer Conditions that by their nature are to be satisfied at the Expiration Date (provided, that such other Offer Conditions would be capable of being satisfied or validly waived were the Expiration Date to occur at such time)) has been satisfied or waived (to the extent waivable by Merger Sub or Parent and has been validly waived) and the Minimum Condition has not been satisfied, then Merger Sub may, and, at the request in writing of SigmaTron, Merger Sub shall, extend the Offer and the Expiration Date for additional periods of up to ten (10) Business Days (calculated as set forth in Rule 14d-1(g)(3) under the Exchange Act) per extension; provided, however, that in no event shall Merger Sub be required to extend the Offer and the Expiration Date pursuant to this third bullet for more than thirty (30) Business Days in the aggregate, and (iv) if, as of the then-scheduled Expiration Date, the Minimum Condition is satisfied but one or more of the other Offer Conditions (other than any such conditions that by their nature are to be satisfied at the Expiration Date (provided, that such other Offer Conditions would be capable of being satisfied or validly waived were the Expiration Date to occur at such time)) is not satisfied (unless such other Offer Condition is waivable by Merger Sub or Parent and has been validly waived), Merger Sub may, and Parent may cause Merger Sub to, extend the Offer.

If the Minimum Condition is satisfied and Merger Sub accepts Shares for payment pursuant to the Offer, Merger Sub will hold a sufficient number of Shares to consummate the Merger under Section 251(h) of the DGCL without submitting the adoption of the Merger Agreement to a vote of the SigmaTron stockholders. Following the consummation of the Offer and subject to the satisfaction of the remaining conditions set forth in the Merger Agreement, Parent, Merger Sub and SigmaTron will take all necessary and appropriate action to effect the Merger as soon as practicable without a meeting of SigmaTron stockholders in accordance with Section 251(h) of the DGCL.

Merger Sub expressly reserves the right to waive, at any time and to the extent permitted by applicable law, in whole or in part, any Offer Condition or modify the terms of the Offer in any manner not inconsistent with the Merger Agreement, except that SigmaTron’s prior written approval is required for Merger Sub to, and for Parent to permit Merger Sub to: (i) amend, modify or waive the Minimum Condition or certain other conditions set forth in the Merger Agreement ; (ii) amend, modify or supplement any of the Offer Conditions in a manner that adversely affects any holder of Shares in its capacity as such; (iii) decrease the Offer Price (other than an adjustment made pursuant to Section 1.1(g) of the Merger Agreement); (iv) change the form of consideration payable in the Offer; (v) decrease the maximum number of Shares sought to be purchased in the Offer; (vi) impose additional conditions to the Offer other than the Offer Conditions; (vii) withdraw or terminate the Offer or extend or otherwise change the Expiration Date; or (viii) provide any “subsequent offering period” (or any extension thereof) within the meaning of Rule 14d-11 promulgated under the Exchange Act.

Any extension, delay, termination or amendment of the Offer will be followed as promptly as practicable by a public announcement thereof, and such announcement in the case of an extension will be made no later than 9:00 a.m., Eastern Time, on the business day after the previously scheduled Expiration Date. Without limiting the manner in which Merger Sub may choose to make any public announcement, Merger Sub intends to make announcements regarding the Offer by issuing a press release and making any appropriate filing with the SEC.

Merger Sub is not providing for guaranteed delivery procedures. Therefore, SigmaTron stockholders must allow sufficient time for the necessary tender procedures to be completed during normal business hours of The Depository Trust Company (“DTC”), which end earlier than the Expiration Date. Normal business hours of DTC are between 8:00 a.m. and 5:00 p.m., Eastern Time, Monday through Friday, other than holidays. SigmaTron stockholders must tender their Shares in accordance with the procedures set forth in the Offer to Purchase and the related Letter of Transmittal prior to the Expiration Date. Tenders received by the Depositary after the Expiration Date will be disregarded and of no effect.

For purposes of the Offer, Merger Sub will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered to Merger Sub and not properly withdrawn as, if and when Merger Sub gives oral or written notice to the Depositary of Merger Sub’s acceptance for payment of such Shares pursuant to the Offer. Upon the terms and subject to the conditions of the Offer, payment for Shares accepted for payment pursuant to the Offer will be made by deposit of the purchase price for such Shares with the Depositary, which will act as agent for tendering stockholders for the purpose of receiving payments from Merger Sub and transmitting such payments to tendering stockholders whose Shares have been accepted for payment. If Merger Sub extends the Offer, is delayed in its acceptance of Shares for payment or is unable to accept Shares for payment pursuant to the Offer for any reason, then, without prejudice to Merger Sub’s rights under the Offer and the Merger Agreement, the Depositary may retain tendered Shares on Merger Sub’s behalf, and such Shares may not be withdrawn except to the extent that tendering stockholders are entitled to withdrawal rights as described in Section 4 of the Offer to Purchase. However, Merger Sub’s ability to delay the payment for Shares that it has accepted for payment is limited by Rule 14e-1(c) under the Exchange Act, which requires Merger Sub to pay the consideration offered or return the securities deposited by or on behalf of stockholders promptly after the termination or withdrawal of the Offer. Under no circumstances will Merger Sub pay interest on the Offer Price for Shares accepted for payment in the Offer, including by reason of any extension of the Offer or any delay in making such payment.

In all cases, Merger Sub will pay for Shares validly tendered and accepted for payment pursuant to the Offer only after timely receipt by the Depositary of (i) the certificates evidencing such Shares (the “Share Certificates”) or confirmation of a book-entry transfer of such Shares into the Depositary’s account at DTC (such a confirmation, a “Book-Entry Confirmation”) pursuant to the procedures set forth in Section 3 of the Offer to Purchase, (ii) the Letter of Transmittal, properly completed and duly executed, with any required signature guarantees (or, in the case of a book-entry transfer or a tender through DTC’s Automated Tender Offer Program, an Agent’s Message (as defined in the Offer to Purchase) in lieu of the Letter of Transmittal) and (iii) any other documents required by the Letter of Transmittal or the Depositary, in each case prior to the Expiration Date. Accordingly, tendering stockholders may be paid at different times depending upon when the Share Certificates and Letter of Transmittal, or Book-Entry Confirmations and Agent’s Message, in each case, with respect to Shares that are actually received by the Depositary.

Shares tendered pursuant to the Offer may be withdrawn at any time prior to the Expiration Date. Thereafter, tenders are irrevocable, except that if Merger Sub has not accepted your Shares for payment within 60 days of commencement of the Offer, you may withdraw them at any time after August 25, 2025, the 60th day after commencement of the Offer, until Merger Sub accepts your Shares for payment.

For a withdrawal of Shares to be effective, the Depositary must timely receive a written notice of withdrawal at one of its addresses set forth on the back cover of the Offer to Purchase. Any notice of withdrawal must specify the name of the person who tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the names in which the Share Certificates are registered, if different from the person who tendered such Shares. The signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution (as defined in the Offer to Purchase), unless such Shares have been tendered for the account of an Eligible Institution. If Shares have been tendered pursuant to the procedures for book-entry transfer as set forth in Section 3 of the Offer to Purchase, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Shares. If Share Certificates representing the Shares to be withdrawn have been delivered or otherwise identified to the Depositary, then, prior to the physical release of such Share Certificates, the name of the holder(s) of record and the serial numbers shown on such Share Certificates must also be furnished to the Depositary.

Withdrawals of tenders of Shares may not be rescinded and any Shares properly withdrawn will be deemed not validly tendered for purposes of the Offer. Withdrawn Shares may, however, be retendered by following one of the procedures for tendering Shares described in Section 3 of the Offer to Purchase at any time prior to the Expiration Date.

All questions as to the validity, form, eligibility (including time of receipt) and acceptance for payment of any tender of Shares will be determined by Merger Sub in its sole discretion, which determination will be final and binding on all parties, subject to the rights of holders of Shares to challenge such determination with respect to their Shares in a court of competent jurisdiction and any subsequent judgment of any such court. Merger Sub reserves the absolute right to reject any and all tenders determined by the Merger Sub not to be in proper form or the acceptance for payment of which may, in Merger Sub’s opinion, be unlawful. Merger Sub also reserves the absolute right to waive any defect or irregularity in the tender of any Shares of any particular stockholder, whether or not similar defects or irregularities are waived in the case of other stockholders. No tender of Shares will be deemed to have been validly made until all defects and irregularities have been cured or waived to Merger Sub’s satisfaction. None of Merger Sub, Parent or any of their respective affiliates or assigns, the Depositary, D.F. King & Co., Inc. (the “Information Agent”) or any other person will be under any duty to give any notification of any defects or irregularities in tenders or incur any liability for failure to give any such notification. Subject to the terms of the Merger Agreement and the rights of holders of Shares to challenge any interpretation with respect to their Shares in a court of competent jurisdiction and any subsequent judgment of any such court, Merger Sub’s interpretation of the terms and conditions of the Offer (including the Letter of Transmittal and the instructions thereto) will be final and binding.

The information required to be disclosed by paragraph (d)(1) of Rule 14d-6 of the General Rules and Regulations under the Exchange Act is contained in the Offer to Purchase and is incorporated herein by reference.
