SUMMARY TERM SHEET
     This summary and the remainder of this Transaction Statement on Schedule 13E-3 include information describing the “going private” merger involving Suntron Corporation and SUNN Acquisition Corporation, how it affects you, what your rights are with respect to the merger as a stockholder of Suntron Corporation, and the position of the people listed on the cover of the Schedule 13E-3 above the caption “Name of Persons Filing Statement,” who are referred to herein as the “Filing Persons,” on the fairness of the merger to you.
Purpose of the Merger (Page 2).
     SUNN Acquisition Corporation, a Delaware corporation (“SUNN Acquisition”), owns approximately 90.1% of the outstanding shares of Suntron Corporation (“Suntron”) common stock. SUNN Acquisition intends to merge with and into Suntron as a means of acquiring all of the other shares of Suntron common stock and to provide a source of liquidity to holders of those shares. Suntron will be the surviving entity of the merger, with the result that it will be 100% owned by SUNN Acquisition’s common stockholders.
Principal Terms of the Merger.
     The Merger (Pages 1 and 23). SUNN Acquisition is a recently formed company created by several of Suntron’s common stockholders. These stockholders contributed all of the shares of Suntron common stock that they owned to SUNN Acquisition in exchange for shares of common stock of SUNN Acquisition. As a result of this contribution, SUNN Acquisition owns approximately 90.1% of Suntron’s outstanding shares. As soon as practicable, SUNN Acquisition will merge with and into Suntron in a “short form” merger under Section 253 of the Delaware General Corporation Law (the “DGCL”). SUNN Acquisition does not intend to enter into a merger agreement with Suntron or to seek the approval of the directors of Suntron for the merger. Stockholders of Suntron will not be entitled to vote their shares with respect to the merger.
     Merger Price (Page 1). Upon the effectiveness of the merger, each share of Suntron stock not owned by any of the Filing Persons will automatically be converted into the right to receive $1.15 in cash, without interest.
     Suntron Shares Outstanding; Ownership by SUNN Acquisition (Pages 1 and 5-6). As of October 3, 2007, a total of 27,618,639 shares of Suntron common stock were outstanding. In addition, as of October 3, 2007, 2,176,458 options to purchase shares of Suntron common stock were outstanding. However, 1,945,826 of these options are exercisable at a price in excess of $1.15 per share. In connection with the merger, (a) all options to purchase shares of Suntron common stock outstanding at an exercise price of $1.15 per share or greater will be cancelled and the option holders will receive no consideration therefor; and (b) all options to purchase shares of Suntron common stock outstanding at an exercise price of less than $1.15 per share will be cancelled and the holders of such options will receive a cash payment amount equal to the number of shares of Suntron common stock subject to these options multiplied by the difference between (i) $1.15 and (ii) the exercise price of such options, which cash payment amount (after reducing such amount by applicable tax withholdings) shall be paid to such option holders. As of October 3, 2007, SUNN Acquisition owned a total of 24,892,751 shares of Suntron common stock, or approximately 90.1% of the outstanding shares of Suntron common stock.
     Payment for Shares (Page 23). SUNN Acquisition will pay you for your shares of Suntron common stock promptly after the effective date of the merger. Instructions for surrendering your stock certificates will be set forth in a Notice of Merger and Appraisal Rights and a Letter of Transmittal, which will be mailed to stockholders of record of Suntron within 10 calendar days following the date the merger becomes effective and should be read carefully. Please do not submit your stock certificates before you have received these documents. Sending us your stock certificates with a properly signed Letter of Transmittal will waive your appraisal rights described below. See Item 4 “Terms of the Transaction” beginning on Page 23 of this Schedule 13E-3.

     Source and Amount of Funds (Page 29). The total amount of funds expected to be required by SUNN Acquisition to pay the merger price for Suntron common stock in the merger, and to pay related fees and expenses, is estimated to be approximately $3.4 million, assuming no outstanding options to acquire Suntron common stock are exercised prior to the merger. SUNN Acquisition intends to borrow the funds necessary to pay the merger price and all related fee and expenses from Thayer Equity Investors IV, L.P., an affiliate of SUNN Acquisition and a Filing Person, and U.S. Bank National Association. The completion of the merger is subject to the completion of the financing on terms that are acceptable to the Filing Persons and the consent of Suntron’s lenders.
The Filing Persons’ Position on the Fairness of the Merger (Page 7).
     The Filing Persons have concluded that the merger is both substantively and procedurally fair to the unaffiliated stockholders of Suntron, based primarily on the following factors:
    The market for Suntron’s shares of common stock has been highly illiquid with average daily trading volume of 7,259 shares during the three-month period ended October 2, 2007. Though the closing price for Suntron common stock on October 2, 2007 was $1.21, the opportunity for a significant number of shares of Suntron common stock to be sold in the market in the foreseeable future, without substantially reducing the market price, is remote.
 
    The merger will enable the unaffiliated stockholders of Suntron to realize cash for their shares, which would otherwise be difficult given the illiquidity of the market for shares of Suntron common stock.
 
    Suntron will no longer be subject to the costly reporting and other disclosure requirements of the Securities Exchange Act of 1934, including those instituted under the Sarbanes-Oxley Act of 2002. Furthermore, Suntron will avoid the significant additional costs of complying with Section 404 of Sarbanes-Oxley, which would otherwise begin to be incurred in late 2007 and which would negatively impact Suntron’s future financial results.
 
    The unaffiliated stockholders of Suntron are entitled to exercise appraisal rights and demand “fair value” for their shares as determined by the Delaware Court of Chancery, which may be determined to be more or less than the cash amount offered in the merger. See “Special Factors—Purposes, Alternatives, Reasons, and Effects of the Merger” and Item 4 “Terms of the Transaction” beginning on Pages 2 and 23, respectively, of this Schedule 13E-3.
     See “Special Factors—Fairness of the Merger—Position of the Filing Persons as to the Fairness of the Merger,” beginning on Page 7 of this Schedule 13E-3.
Consequences of the Merger (Page 5).
     Completion of the merger will have the following consequences:
    Suntron will be a privately held corporation, with the stockholders of SUNN Acquisition owning 100% of the equity interest in Suntron and its business.
 
    Only the stockholders of SUNN Acquisition will have the opportunity to participate in the future earnings and growth, if any, of Suntron. Similarly, only the stockholders of SUNN Acquisition will face the risk of losses generated by Suntron’s operations or the decline in value of Suntron after the merger.
 
    The shares of Suntron common stock will no longer be publicly traded. In addition, Suntron will no longer be subject to the reporting and other disclosure requirements of

-ii-


Table of Contents

      the Securities Exchange Act of 1934, including requirements to file annual and other periodic reports or to provide the type of going private disclosure contained in this Schedule 13E-3.
 
    Subject to the exercise of statutory appraisal rights, each of your shares will be converted into the right to receive $1.15 per share in cash, without interest.
Appraisal Rights (Page 24).
     You have a statutory right to dissent from the merger and demand payment of the fair value of your Suntron shares as determined in a judicial appraisal proceeding in accordance with Section 262 of the DGCL, plus interest, if any, from the date of the merger. This value may be more or less than the $1.15 per share in cash consideration offered in the merger. In order to qualify for these rights, you must make a written demand for appraisal within 20 days after the date of mailing of the Notice of Merger and Appraisal Rights and otherwise comply with the procedures for exercising appraisal rights set forth in the DGCL. The statutory right of dissent is set out in Section 262 of the DGCL and is complicated. A copy of Section 262 is attached as Exhibit (f) hereto. Any failure to comply with its terms will result in an irrevocable loss of such right. Stockholders seeking to exercise their statutory right of dissent are encouraged to seek advice from legal counsel. See Item 4(d) “Terms of the Transaction—Appraisal Rights” beginning on Page 24 of this Schedule 13E-3.
Where You Can Find More Information (Page 21).
     More information regarding Suntron is available from its public filings with the Securities and Exchange Commission. See Item 2 “Subject Company Information” and Item 3 “Identity and Background of Filing Persons” beginning on Pages 21 and 22, respectively, of this Schedule 13E-3.

INTRODUCTION
     This Transaction Statement on Schedule 13E-3 (the “Schedule 13E-3”) is being filed by SUNN Acquisition Corporation, a Delaware corporation (“SUNN Acquisition”), Thayer-Blum Funding III, L.L.C., a Delaware limited liability company and majority stockholder of SUNN Acquisition (“Thayer-Blum”), Thayer | Hidden Creek Partners, L.L.C., a Delaware limited liability company (“Thayer | Hidden Creek Partners”), TC Equity Partners IV, L.L.C., a Delaware limited liability company (“TC Equity Partners”), Thayer | Hidden Creek Management, L.P., a Delaware limited partnership (“Thayer | Hidden Creek Management”), TC Co-Investors IV, L.L.C., a Delaware limited liability company (“TC Co-Investors”), Thayer Equity Investors IV, L.P., a Delaware limited partnership (“Thayer Equity”), TC Manufacturing Holdings, L.L.C., a Delaware limited liability company (“TC Manufacturing”), and TC KCo, L.L.C., a Delaware limited liability company (“TC KCo,” and together with Thayer | Hidden Creek Partners, TC Equity Partners, Thayer | Hidden Creek Management, TC Co-Investors, Thayer Equity, and TC Manufacturing, the “Thayer Entities”), pursuant to Section 13(e) of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13e-3 thereunder. The Thayer Entities, together with SUNN Acquisition and Thayer-Blum, are referred to in this Schedule 13E-3 as the “Filing Persons.” This Schedule 13E-3 is being filed in connection with a short-form merger (the “Merger”) of SUNN Acquisition with and into Suntron Corporation, a Delaware corporation (“Suntron”), pursuant to Section 253 of the Delaware General Corporation Law (the “DGCL”). The effective date (the “Effective Date”) of the Merger is expected to be December 7, 2007 or as soon thereafter as possible.
     As of October 3, 2007, there were issued and outstanding 27,618,639 shares of common stock, $0.01 par value per share (the “Shares”), of Suntron. As of October 3, 2007, SUNN Acquisition held a total of 24,892,751 Shares, or approximately 90.1% of the total Shares outstanding. On the Effective Date, SUNN Acquisition intends to acquire the Shares that SUNN Acquisition does not then own through the Merger.
     Upon the consummation of the Merger, each outstanding Share will be cancelled and each outstanding Share (other than Shares held by SUNN Acquisition and stockholders of Suntron who properly exercise statutory appraisal rights under the DGCL) will be automatically converted into the right to receive $1.15 per Share in cash (the “Merger Price”), without interest, upon surrender of the certificate for such Share to Computershare Trust Company, Inc. (the “Paying Agent”). The Paying Agent’s address and telephone number are: 350 Indiana Street, Suite 800, Golden, Colorado 80401, Attn: Sean Mclimans, (303) 262-0789.
     Instructions with regard to the surrender of stock certificates, together with a description of statutory appraisal rights, will be set forth in a Notice of Merger and Appraisal Rights and a Letter of Transmittal, which documents will be mailed to stockholders of record of Suntron within 10 calendar days following the Effective Date and should be read carefully.
     Under the DGCL, no action is required by the Board of Directors or the stockholders of Suntron, other than SUNN Acquisition, for the Merger to become effective. Suntron will be the surviving corporation in the Merger. As a result of the Merger, the stockholders of SUNN Acquisition (the “SUNN Acquisition Stockholders”) will be the only stockholders of Suntron.
     As of October 3, 2007, options to purchase a total of 2,176,458 Shares (the “Options”) were outstanding. The exercise prices of the outstanding Options range from $0.01 to $52.52. In connection with the Merger, (a) all Options outstanding at an exercise price of $1.15 per share or greater will be cancelled and the option holders will receive no consideration therefor; and (b) all Options outstanding at an exercise price of less than $1.15 per share will be cancelled and the holders of such Options will receive a cash payment amount equal to the number of shares of Suntron common stock subject to these options multiplied by the difference between (i) $1.15 and (ii) the exercise price of such options, which cash payment amount (after reducing the amount for applicable tax withholdings) shall be paid to such option holders.

SPECIAL FACTORS
PURPOSE, ALTERNATIVES, REASONS, AND EFFECTS OF THE MERGER
Purposes
     On October 3, 2007, the Board of Directors of SUNN Acquisition authorized the management of SUNN Acquisition to proceed with a proposal to merge SUNN Acquisition with and into Suntron. The purpose of the Merger is for the SUNN Acquisition Stockholders to acquire the minority public interest in Suntron and to provide Suntron’s stockholders other than SUNN Acquisition (the “Unaffiliated Stockholders”) with $1.15 in cash, without interest, for each of their Shares. Following the Merger, the SUNN Acquisition Stockholders will hold 100% ownership of Suntron. SUNN Acquisition believes that the extremely limited trading volume in the Shares makes ownership of the Shares unattractive to the Unaffiliated Stockholders because the Shares are not readily saleable in the public market. SUNN Acquisition also believes that, given Suntron’s very small public float (estimated to be approximately $3.3 million as of October 2, 2007), the costs of maintaining Suntron’s status as a public company are not justified.
Background
     Thayer-Blum acquired its shares of Suntron common stock in 2002. Since that time, Thayer-Blum has monitored the performance of Suntron and considered and assessed its investment in Suntron from time to time. In connection with its assessments of its Suntron investment, Thayer-Blum has considered potential strategic transactions, business combinations, and other alternatives to maximize the value of its investment. However, Thayer-Blum determined to retain its investment in Suntron, a business combination transaction was not pursued and Thayer-Blum continued to monitor the performance of Suntron.
     During 2005, one of Suntron’s competitors approached representatives of Blum Capital Partners, L.P. (“Blum Capital Partners”), a member of Thayer-Blum, to express their interest in possibly acquiring 100% of Suntron’s stock. Suntron’s board of directors formed a committee to pursue discussions with the competitor. While preliminary discussions were held, these discussions were discontinued as no formal offer was forthcoming and none of Suntron, Thayer-Blum, Blum Capital Partners or any other member of Thayer-Blum has received an offer regarding this possible acquisition or any other third party acquisition.
     During the fall of 2006, during the course of its regular review of its Suntron investment, Thayer Equity and Thayer-Blum discussed the status of its investment in Suntron, the company’s efforts to achieve profitability, and possible alternatives with respect to its investment, including a going private transaction. However, none of these discussions resulted in a decision by Thayer Equity or Thayer-Blum to pursue a going private transaction at such time.
     Late in the summer of 2007, Thayer Equity and Thayer-Blum again discussed the status of its investment in Suntron, the company’s continued lack of profitability, and the upcoming SOX 404 compliance deadline. Thayer Equity and Thayer-Blum continued to discuss possible alternatives either to improve Suntron’s financial performance to justify incurring the expenses of SOX 404 compliance or to eliminate the burden and cost of public company reporting, including SOX 404 compliance, on Suntron as a way to improve Suntron’s financial performance. Thayer Equity and Thayer-Blum discussed various alternatives, including staying public, a going private transaction and a third party acquisition. Because Thayer-Blum desired to retain its investment in Suntron, Thayer-Blum did not pursue a third party acquisition. With respect to a going private transaction, the filing persons discussed the various principal terms of such a transaction, the likely response of the Unaffiliated Stockholders and management of the Company to a going private transaction, the availability of financing for the proposed transaction, the ability to structure the proposed transaction as a short-form merger, and the timetable for completing the transaction.
     After numerous discussions and negotiations among Thayer Equity, Thayer-Blum and the other SUNN Acquisition Stockholders, on October 3, 2007, the SUNN Acquisition Stockholders agreed to the terms of and entered into the Contribution Agreement and filed this Schedule 13E-3 with the Securities and Exchange Commission. On the same day, Thayer-Blum and its members filed Amendment No. 1 to its Schedule 13D with the Securities and Exchange Commission.
Alternatives
     The Filing Persons believe that effecting the transaction by way of a short-form merger with SUNN Acquisition under Section 253 of the DGCL is the quickest and most cost effective way for the SUNN Acquisition Stockholders to acquire the outstanding public minority equity interest in Suntron. The Filing Persons considered and rejected the alternative of a long-form merger because of the cost and delay of obtaining the approvals of Suntron’s Board of Directors and of the Unaffiliated Stockholders of Suntron. The Filing Persons also rejected the alternative of a tender offer as it entailed additional costs and a subsequent short-form merger would likely still be required.
Reasons
     In determining whether to acquire the outstanding public minority equity interest in Suntron and to effect the Merger, the Filing Persons considered the following factors to be the principal benefits of taking Suntron private:
    the decrease in costs associated with being a public company (for example, as a privately held entity, Suntron would no longer be required to file quarterly, annual, or other periodic reports with the Commission, publish and distribute to its stockholders annual reports and proxy statements, comply with the Sarbanes-Oxley Act of 2002 (“SOX”), or begin to comply with Section 404 of SOX (“SOX 404”) as of December 31, 2007), which the Filing Persons anticipate should result in (a) savings of approximately $687,000 per year in costs related to being a public company (excluding SOX 404 compliance costs), and (b) avoidance of approximately $2,800,000 in initial SOX 404 implementation costs in 2008, and ongoing additional costs of approximately $625,000 per year thereafter, to comply with SOX 404;
 
    the elimination of additional burdens on management associated with public reporting and other tasks resulting from Suntron’s public company status, including, for example, the dedication of time by and resources of Suntron’s management and Board of Directors to stockholder inquiries and investor and public relations;
 
    the greater flexibility that Suntron’s management would have to focus on long-term business goals, as opposed to quarterly earnings, as a non-reporting company; and

2


Table of Contents

    the fact that the public market offers very little liquidity for investors, as average daily trading volume of Suntron’s Shares during the three-month period ended October 2, 2007 was only 7,259 Shares, and the fact that if Suntron fails to meet the listing requirement of the Nasdaq SmallCap Market to maintain a minimum bid price of $1.00 per Share (from August 7, 2007 through August 16, 2007, Suntron had eight straight days in which its minimum bid price closed at less than $1.00 per Share; however, as of October 2, 2007 Suntron’s per Share price was $1.21), investors may have no public market in which to efficiently sell their Shares.
     Most of the requirements of SOX are now effective and applicable to Suntron, and Suntron has implemented procedures intended to comply with those currently applicable requirements. However, one very substantial requirement of SOX, SOX 404, will first be applicable to Suntron for the year ending December 31, 2007. In general terms, compliance with SOX 404 will soon require the following:
    Suntron will be required to document and test its internal control procedures; and
 
    Suntron’s management will be required to assess and issue a report concerning Suntron’s internal control over financial reporting.
Additionally, Suntron’s independent registered public accounting firm will be required to attest to and report on the effectiveness of Suntron’s internal control over financing reporting for the year ending December 31, 2008 and beyond.
     These requirements, particularly with respect to SOX 404, are expected to result in immediate and significant increased expenses, including the investment of management time to implement the requirements in 2007, increased legal and consulting fees, and the increased annual charges from Suntron’s public accounting firm. The rules governing the standards that must be met for management to assess Suntron’s internal control over financial reporting are new and complex, and require significant documentation, testing, and possible remediation to meet the detailed standards under the rules. These increased expenses will negatively impact Suntron’s financial results in 2007 and beyond if Suntron remains a public company.
     The Filing Persons also considered the advantages and disadvantages of certain alternatives to acquiring the minority stockholder interest in Suntron, including leaving Suntron as a majority-owned, public subsidiary. In the view of the Filing Persons, the principal advantage of leaving Suntron as a majority-owned, public subsidiary would be the potential investment liquidity of owning securities of a public company and the possibility for use of Suntron’s securities to raise capital or make acquisitions. However, Suntron has not taken advantage of these benefits, and the Filing Persons do not expect Suntron to do so in the foreseeable future. The Filing Persons also noted that companies of similar size and public float to Suntron do not typically receive the necessary attention from stock analysts and the investment community to create substantial liquidity.
     The Filing Persons also considered a variety of risks and other potentially negative factors for the Unaffiliated Stockholders and the Filing Persons concerning the Merger, including the fact that:
    following the Merger, if Suntron’s financial condition improves, the Unaffiliated Stockholders will not participate in any future earnings of or benefit from any increases in Suntron’s value, and only the Filing Persons would benefit by an increase in the value of Suntron;
 
    for U.S. federal income tax purposes generally, the cash payments made to the Unaffiliated Stockholders pursuant to the Merger will be taxable to the Unaffiliated Stockholders;
 
    the Unaffiliated Stockholders have not been represented in discussions about the Merger, either by the Board of Directors of Suntron (which, by statute, is not involved in the short-

3


Table of Contents

      form merger process) or an independent committee representing the interests of the Unaffiliated Stockholders;
 
    if Suntron continues as a going concern in the future, the Filing Persons and Suntron will be the sole beneficiaries of the cost savings that result from going private; and
 
    the Filing Persons did not engage any third parties to perform any financial analysis of, or prepare any reports, opinions, or appraisals concerning the Merger or value of the Shares.
     The Filing Persons determined that if they had suspended Suntron’s filing and other obligations under the Exchange Act, Suntron would have achieved cost savings in excess of $500,000 for each of the past two fiscal years with respect to the public reporting requirements. For the twelve months ended July 1, 2007, Suntron incurred approximately $687,000 for expenses that the Filing Persons believe could have been eliminated if Suntron had been a privately held company. These costs include director and officer liability insurance premiums of approximately $180,000, compensation to employees of approximately $180,000, independent auditor fees of approximately $95,000, legal fees of approximately $79,000, and transfer agent, printing, and other costs related to being a public company of approximately $153,000. Such estimated cost savings weighed in favor of effecting the Merger.
     In addition, the Filing Persons estimate the costs of compliance with SOX 404 to be as follows:
                 
    Initial     Ongoing Annual  
    Implementation Costs     Expense  
New compliance personnel
  $ 350,000     $ 300,000  
Implementation consultants
    2,400,000        
Independent auditor attestation
    50,000       325,000  
 
           
Total
  $ 2,800,000     $ 625,000  
 
           
     The principal disadvantage of leaving Suntron as a majority-owned, public subsidiary considered by the Filing Persons is the inability to achieve the significant cost-saving benefits discussed above. The Filing Persons believe that Suntron management has reduced corporate overhead as much as possible, and that the costs associated with being a public reporting company represent a significant portion of Suntron’s total overhead. The Filing Persons believe these costs will only continue to increase. In sum, the Filings Persons concluded that the advantages of leaving Suntron as a majority-owned, public subsidiary were significantly outweighed by the disadvantages of doing so, and accordingly that alternative was rejected.
     The Filing Persons also considered the low volume of trading in the Shares and considered the fact that the Merger would result in immediate, enhanced liquidity for the Unaffiliated Stockholders. In addition, the Filing Persons considered the downward trends in the price of the Shares during the past 12 months. While the reported sale prices and reported bid and asked prices of the Shares at times have been in excess of the Merger Price over the past year, the Filing Persons believe that the market for the Shares is so illiquid that all Unaffiliated Stockholders would not be able to sell their shares within a short period of time at or above the currently reported Merger Price. The Merger offers all Unaffiliated Stockholders the opportunity to sell their shares for one price at the same time, without the payment of any brokerage fee or commission, and thereby benefits the Unaffiliated Stockholders.
     The Filing Persons have determined to effect the Merger at this time (i.e., on or about December 7, 2007) because they wish to immediately realize the benefits of taking Suntron private, as discussed above. In particular, the Filing Persons desire that Suntron avoid the significant costs of

complying with SOX 404, which Suntron will otherwise have to comply with as of December 31, 2007. Suntron’s management has undertaken a series of restructuring activities since 2005 to reduce operating expenses to achieve profitability. However, based on Suntron’s financial results in 2007, the Filing Persons do not believe Suntron will be profitable in 2008 if it remains a public company and incurs the additional costs associated with SOX 404 compliance. Suntron’s stock price was not a significant factor in the timing of the Filing Persons’ decision to propose the Merger.
     This Rule 13e-3 transaction is structured as a short-form merger under Section 253 of the DGCL. This form of merger allows the Unaffiliated Stockholders to receive cash for their Shares quickly and allows Suntron to become a privately held company without any action by the Board of Directors of Suntron or the Unaffiliated Stockholders.
Effects
     General. Upon completion of the Merger, the SUNN Acquisition Stockholders will have complete control over the conduct of Suntron’s business and will have a 100% interest in the net assets, net book value, and net earnings of Suntron. In addition, upon completion of the Merger, only the SUNN Acquisition Stockholders will receive the benefit of the right to participate in any future increases in the value of Suntron and will bear the risk of any losses incurred in the operation of Suntron and any decrease in the value of Suntron. The SUNN Acquisition Stockholders will indirectly realize all of the benefit in the estimated savings of approximately $687,000 per year in costs related to being a public company (excluding SOX 404 compliance costs) and the avoidance of approximately $2,800,000 in initial SOX 404 implementation costs in 2008, and ongoing SOX 404 compliance costs of approximately $625,000 per year thereafter. The beneficial ownership of the SUNN Acquisition Stockholders in Suntron immediately prior to the Merger amounts to approximately 90.1% in the aggregate. Upon completion of the Merger, their interest in Suntron’s book value (approximately $42.3 million as of September 30, 2007) and net loss (approximately $(1.8) million for the nine months ended September 30, 2007), will increase from approximately 90.1% to 100% of those amounts.
     Stockholders. Upon completion of the Merger, the Unaffiliated Stockholders will no longer have any interest in, and will not be stockholders of, Suntron and therefore will not participate in Suntron’s future earnings and potential growth and will no longer bear the risk of any decreases in the value of Suntron. In addition, the Unaffiliated Stockholders will not share in any distribution of proceeds after any sales of businesses of Suntron, whether contemplated at the time of the Merger or thereafter. See Item 6(c) “Purposes of the Transaction and Plans or Proposals—Plans,” beginning on Page 29 of this Schedule 13E-3. All of the Unaffiliated Stockholders’ other incidents of stock ownership, such as the right to vote on certain corporate decisions, to elect directors, to receive distributions upon the liquidation of Suntron, and to receive appraisal rights upon certain mergers or consolidations of Suntron (unless such appraisal rights are perfected in connection with the Merger) will be extinguished upon completion of the Merger. Instead, the Unaffiliated Stockholders will have liquidity, in the form of the Merger Price, in place of an ongoing equity interest in Suntron, in the form of the Shares. However, the Unaffiliated Stockholders will be required to surrender their Shares involuntarily in exchange for the Merger Price and will not have the right to liquidate the Shares at a time and for a price of their choosing. In summary, if the Merger is completed, the Unaffiliated Stockholders will have no ongoing rights as stockholders of Suntron (other than statutory appraisal rights in the case of Unaffiliated Stockholders who are entitled to and perfect such rights under Delaware law).
     The Shares. Once the Merger is consummated, public trading of the Shares will cease. The Filing Persons intend to deregister the Shares under the Exchange Act. As a result, Suntron will no longer be required to file annual, quarterly, and other periodic reports with the Commission under Section 13(a) of the Exchange Act, will no longer be subject to the proxy rules under Section 14 of the Exchange Act, and will no longer be required to comply with SOX 404. In addition, the principal stockholder of Suntron will no longer be subject to reporting its ownership of Shares under Section 13 of the Exchange Act or to the requirement under Section 16 of the Exchange Act to disgorge to Suntron certain profits from the purchase and sale of Shares.
     The Options. As of October 3, 2007, Suntron had outstanding Options to purchase 2,176,458 Shares. Such Options have exercise prices that range from $0.01 to $52.52. In connection with the Merger, (a) all Options outstanding at an exercise price of $1.15 per share or greater will be cancelled and the option holders will receive no consideration therefor; and (b) all Options outstanding at an

5

exercise price of less than $1.15 per share will be cancelled and the holders of such Options will receive a cash payment amount equal to the number of shares of Suntron common stock subject to these options multiplied by the difference between (i) $1.15 and (ii) the exercise price of such options, which cash payment amount (after reducing such amount by applicable tax withholdings) shall be paid to such option holders.
U.S. FEDERAL INCOME TAX CONSIDERATIONS
     The following is a summary of the material U.S. federal income tax consequences of the Merger to the Unaffiliated Stockholders. The Merger will not have any material tax consequences to the Filing Persons. The discussion does not cover all aspects of U.S. federal income taxation that may be relevant to particular investors and does not address state, local, foreign, or other tax laws. In particular, this summary does not discuss all of the tax considerations that may be relevant to certain taxpayers subject to special treatment under the U.S. federal income tax laws (such as financial institutions, insurance companies, investors liable for the alternative minimum tax, individual retirement accounts and other tax-deferred accounts, tax-exempt organizations, dealers in securities or currencies, investors whose functional currency is not the U.S. dollar, or investors other than a United States Holder).
     For purposes of this summary, the term “United States Holder” means a beneficial owner of Shares that, for United States federal income tax purposes, is
    an individual who is a citizen or resident of the United States;
 
    a corporation or other entity taxable as a corporation that is created or organized in or under the laws of the United States or any state (including the District of Columbia);
 
    an estate the income of which is subject to United States federal income tax regardless of its source; or
 
    a trust, in general, if a court within the United States is able to exercise primary supervision over the administration of the trust, and one or more United States persons (within the meaning of the Internal Revenue Code) have the authority to control all substantial decisions of the trust.
     This summary is based on the tax laws of the United States, including the Internal Revenue Code of 1986, as amended, its legislative history, existing and proposed regulations thereunder, published rulings, and court decisions all as currently in effect and all subject to change at any time, possibly with retroactive effect.
     ALL BENEFICIAL OWNERS OF SHARES SHOULD CONSULT THEIR TAX ADVISER AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL, FOREIGN, AND OTHER TAX LAWS AND POSSIBLE CHANGES IN TAX LAW.
     The receipt of cash by a stockholder, pursuant to the Merger or pursuant to the stockholder’s statutory appraisal rights, will be a taxable transaction for U.S. federal income tax purposes and may also be taxable for state and local income tax purposes as well. A stockholder will generally recognize capital gain or loss for federal income tax purposes equal to the difference, if any, between the amount of cash the stockholder receives in the Merger and the stockholder’s adjusted tax basis in the Shares. A stockholder’s basis in a Share will generally be the cost at which it was purchased. Capital gain or loss will be long-term capital gain or loss if the stockholder had held the Shares for more than one year.
     The cash payments made to stockholders pursuant to the Merger will be reported to the Internal Revenue Service and to the stockholder as may be required under applicable regulations. Backup withholding may apply to these payments if the stockholder fails to provide an accurate taxpayer identification number or certification of exempt status or fails to report all interest and dividends required

to be shown on its U.S. federal income tax returns. Certain stockholders (including, among others, corporations) are not subject to backup withholding. Stockholders should consult their tax advisers as to their qualification for exemption from backup withholding and the procedure for obtaining an exemption.
FAIRNESS OF THE MERGER
Position of the Filing Persons as to the Fairness of the Merger
     Because each of the Filing Persons are the beneficial owners of a majority of the Shares, such Filing Persons are “affiliates” of Suntron within the meaning of Rule 13e-3 under the Exchange Act. Accordingly, each of the Filing Persons is expressing its belief as to the substantive and procedural fairness of the Merger to the Unaffiliated Stockholders.
     Each of the Filing Persons has determined that the Merger is both substantively and procedurally fair to the Unaffiliated Stockholders (and that at least fair value is being paid for the Shares). This belief is based on the following factors:
•      Financial Analysis. In considering the fairness of the Merger from a financial point of view to the Unaffiliated Stockholders, the Filing Persons reviewed and adopted an analysis of the ranges of potential values of the Shares that result from the application of generally accepted valuation methodologies. This financial analysis, including the selection of valuation methodologies, was prepared by the Filing Persons. The financial analyses undertaken by the Filing Persons included the following:
Analyses based on Public Comparables:
  (i)   multiples of earnings before interest, taxes, depreciation, and amortization (“EBITDA”) (including calendar year 2006 (“CY 2006A”) EBITDA, 12 months ended July 1, 2007 (“LTM”) EBITDA, and estimated calendar year 2007 (“CY 2007E”) EBITDA);
 
  (ii)   multiples of revenue (including CY 2006A revenue, LTM revenue, and CY 2007E revenue);
 
  (iii)   multiples of net tangible assets (defined as total current assets less cash and equivalents and short-term investments less total current liabilities (net of current portions of debt) plus net property, plant and equipment); and
 
  (iv)   multiples of net book value (defined as total assets minus total liabilities).
Analyses based on Precedent Transactions:
  (v)   multiples of LTM EBITDA, multiples of LTM revenue, and premiums/discounts paid on the target’s average closing stock price for the 30 trading day period prior to announcement in precedent transactions in which the target’s business has been deemed by the Filing Persons to be similar to Suntron’s business.
     For items (i) through (iv), the Filing Persons calculated the appropriate multiples by analyzing the financial data of companies engaged in businesses which the Filing Persons, as confirmed by Suntron management, judged to be analogous to Suntron’s business (the “Comparables”). When considering appropriate multiples for items (i) through (iv), it is important to note that most Comparables are in significantly better financial health than Suntron. Specifically, the Comparables are mostly profitable, while Suntron generated negative EBITDA for the CY 2006A and the LTM period. For this reason, analysis based on EBITDA would not provide meaningful results. Therefore, for items (i), (ii) and (v), it was necessary for the Filing Persons to adjust Suntron’s historical EBITDA upwards, per data provided by Suntron management, to a positive number, by eliminating certain non-recurring expenses, that could

then be used to perform market multiple analyses. While Suntron management forecasts positive CY 2007E EBITDA, the Filing Persons elected to adjust estimated CY 2007E EBITDA upwards for items (i) and (iv), per estimates provided by Suntron management, to maintain consistent analyses with the CY 2006A and LTM periods.
     The table below sets forth the upward adjustments to EBITDA for certain non-recurring costs made by the Filing Persons in calculating Suntron’s adjusted EBITDA for CY 2006A, LTM, and CY 2007E.

(a)   Per equity research reports.
     EBITDA multiple analysis is useful as a valuation technique because, unlike earnings multiple analysis, it makes it easier to compare the operating performance of companies in a similar industry where one company is highly leveraged and the other is not. EBITDA can be considered an estimation of a company’s ability to generate cash from operations. EBITDA multiples are calculated by dividing a company’s enterprise value, which is the value of a company’s equity, plus debt, plus minority interest, minus cash, by the Company’s EBITDA. Enterprise value is an indicator of how the market attributes value to a firm as a whole ongoing entity. The Filing Persons have calculated the value of a company’s equity as the product of the company’s stock price multiplied by the fully diluted number of shares outstanding, which is calculated using the treasury stock method. As indicated, the Comparables’ enterprise values are an average of 8.3x CY 2006A EBITDA, 8.6x LTM EBITDA, and 8.0x CY 2007E EBITDA. CY 2007E EBITDA was only available for a subset of the Comparables. EBITDA estimates for the Comparables were obtained individually from equity research reports. To calculate the price per Share based on EBITDA multiples for CY 2006A, LTM, and CY 2007E, the Filing Persons divided the implied equity value of Suntron (as calculated using the EBITDA multiples) by the number of fully diluted

shares outstanding for the period ended July 1, 2007 at each individual valuation (calculated using the treasury stock method).

(a)   Per equity research reports.
     Revenue multiples are calculated by dividing a company’s enterprise value by its revenue. As indicated, the Comparables’ have an average enterprise value of 0.44x CY 2006A Revenue, 0.41x LTM Revenue, and 0.35x CY 2007E Revenue. CY 2007E Revenue was only available for a subset of the Comparables. Revenue estimates for the Comparables were obtained individually from equity research reports. Based on an analysis of the Comparables, there is a close correlation between a company’s revenue multiple and its EBITDA margin. In general, companies with higher EBITDA margins will have higher revenue multiples, as EBITDA is a more true indication of a company’s ability to generate cash from revenue. If Suntron’s EBITDA margin for the three aforementioned analysis periods was or is estimated to be close to the average respective EBITDA margins of the Comparables, 0.44x CY 2006A Revenue, 0.41x LTM Revenue, and 0.35x CY 2007E Revenue would be adequate multiples to use when determining equity value. However, because Suntron’s EBITDA margin for each respective analysis period was or is expected to be significantly below that of the Comparables’ on average, the Filing Persons adjusted the multiple down from the average to a multiple more appropriate for Suntron based

on its lower EBITDA margins. To calculate the appropriate multiple, the Filing Persons determined the relationship between the Comparables’ revenue multiple and their EBITDA margins using linear regression. Otherwise, to have used a strict average of revenue multiples under these circumstances would have overstated Suntron’s actual value. Described in a different way and using the example of CY 2006A, a 0.44x multiple of CY 2006A Revenue implies that a company generates a CY 2006A EBITDA margin of 4.7%. Suntron generated a negative EBITDA margin during CY 2006A (significantly less than 4.7%) and, therefore, the Filing Persons deemed it inappropriate to use a 0.44x revenue multiple to value Suntron’s equity based on CY 2006A Revenue.
     To derive the value of Suntron’s equity using the multiple of revenue method, the Filing Persons considered Suntron’s EBITDA margin when determining the appropriate multiple of revenue to use. By plotting the Comparables’ multiples of revenue as a function of EBITDA margin, the Filing Persons determined that the relationship between the two variables can be expressed by an equation, derived by linear regression (which is a technique in which a straight line is fitted to a set of data points to measure the effect of a single independent variable) as set out in the chart graphics below:
(FLOW CHART)
     To calculate the implied price per Share based on multiples of CY 2006A Revenue, LTM Revenue, and CY 2007E Revenue, the Filing Persons divided the implied equity value of Suntron (as calculated using the revenue multiples) by the number of fully diluted shares outstanding for the period ended July 1, 2007 at each individual valuation (calculated using the treasury stock method).
     Using the calculations for Suntron’s Adjusted EBITDA and assumptions for revenue multiples in the linear regressions above, the Filing Persons calculated the per Share value of Suntron based on revenue multiple analysis as follows:

Net Tangible Assets Multiple Valuation. To calculate the equity value of Suntron based on a net tangible assets multiple valuation method, the Filing Persons compared Suntron’s net tangible assets as of July 1, 2007 to that of the Comparables at the end of each of their latest respective accounting periods. Based on discussions with Suntron management, the Filing Persons reviewed the financial information of the following Comparables:

     Net tangible asset multiples are calculated by dividing a company’s enterprise value by its net tangible assets. As indicated, the Comparables’ have an average enterprise value of 2.03x net tangible assets. Based on an analysis of the Comparables, there is a correlation between a company’s net tangible asset multiple and its EBITDA margin. In general, companies with higher EBITDA margins will have higher net tangible asset multiples, as EBITDA is an indication of a company’s ability to generate cash from net tangible assets. Ideally the Filing Persons would have analyzed the correlation between net tangible assets and EBITA (earnings before interest, taxes, and amortization) as the level of depreciation is dictated by the level of property, plant, and equipment. However, since even on an adjusted basis, Suntron generated negative EBITA during the LTM period ended July 1, 2007, the Filing Persons deemed this analysis inconclusive and instead chose to use EBITDA as the closest proxy for EBITA. If Suntron’s LTM EBITDA as a percentage of net tangible assets as of July 1, 2007 was close to the average of the Comparables, 2.03x would be an adequate net tangible asset multiple to use when determining equity value. However, because Suntron’s LTM EBITDA as a percentage of net tangible assets was negative and, therefore, significantly below that of the Comparables’ on average, the Filing Persons adjusted the multiple down from the average to a multiple more appropriate for Suntron based on its lower LTM EBITDA as a percentage of net tangible assets. To calculate the appropriate multiple, the Filing Persons determined the relationship between the Comparables’ net tangible assets multiple and their LTM EBITDA as a percentage of net tangible assets using linear regression. Otherwise, to have used a strict average of net tangible assets multiples under these circumstances would have overstated Suntron’s actual value. Described in a different way, a 2.03x multiple of net tangible assets implies that a company’s LTM EBITDA as a percentage of net tangible assets is 21.0%. Suntron’s LTM EBITDA as a percentage of net tangible assets was far less than 21.0%, and, therefore, the Filing Persons deemed it inappropriate to use a 2.03x net tangible assets multiple to value Suntron’s equity based on net tangible assets as of July 1, 2007.
     By plotting the Comparables’ multiples of net tangible assets as a function of LTM EBITDA as a percentage of net tangible assets, the Filing Persons determined that the relationship between the two variables can be expressed by an equation, derived by linear regression as set out in the chart graphic below:

Net Book Value Multiple Valuation. The Filing Persons calculated the per Share value of the Company using an analysis of the Comparables’ net book value. The book value multiple is derived by dividing book value into equity value. The book value multiple is a measure of how efficiently a company uses the stockholders’ equity to generate income. Generally, companies that trade at a high multiple to book value generate earnings more efficiently than those that trade at a low multiple to book value. Based on discussions with Suntron management, the Filing Persons reviewed the financial information of the following Comparables:

     Net book value per share is calculated by dividing a company’s net book value by the number of fully diluted shares outstanding (using the treasury stock method). Net book value multiples are then calculated by dividing a company’s current share price by its net book value per share. As indicated, the average of the Comparables’ price divided by net book value per share is 1.38x. Based on an analysis of the Comparables, there is a correlation between a company’s net book value multiple and its LTM EBITDA as a percentage of net book value. In general, companies with higher LTM EBITDA as a percentage of net book value will have higher net book value multiples, as EBITDA is an indication of a company’s ability to generate cash from net book value. Ideally the Filing Persons would have analyzed the correlation between net book value and net income in terms of return on equity (“ROE”), which is derived by dividing net book value into net income. However, since even on an adjusted basis, Suntron generated negative net income during the LTM period ended July 1, 2007, the Filing Persons deemed this analysis inconclusive and instead chose to use EBITDA as a measure of earnings. If Suntron’s LTM EBITDA as a percentage of net book value as of July 1, 2007 was close to the average of the Comparables, 1.38x would be an adequate net book value multiple to use when determining equity value. However, because Suntron’s LTM EBITDA as a percentage of net book value was negative and, therefore, significantly below that of the Comparables’ on average, the Filing Persons adjusted the multiple down from the average to a multiple more appropriate for Suntron based on its lower LTM EBITDA as a percentage of net book value.

     Since the Filing Persons, in part based on discussions with Suntron management, believe that the acquisition of Solectron Corp. by Flextronics International Ltd. is the most recent and pertinent of the precedent transactions, the Filing Persons elected to consider and display a separate analysis and implied valuation based on this transaction.
     To calculate implied price per Share based on an LTM Adjusted EBITDA multiple, the Filing Persons divided the implied equity value of Suntron (as calculated using the LTM EBITDA multiples) by the number of fully diluted shares outstanding for the period ended July 1, 2007 at each individual valuation (calculated using the treasury stock method).
     Using the calculations for Suntron’s LTM Adjusted EBITDA and the average multiple for LTM EBITDA above of 12.3x, as well as the 8.8x multiple for the Solectron Corp./Flextronics International Ltd. transaction, the Filing Persons calculated the per Share value of Suntron based on LTM EBITDA multiple analysis, as it relates to selected precedent transactions, as follows:

     As a result, the analysis based upon multiples of LTM EBITDA indicated values of approximately negative $0.11 and negative $0.38 per Share.
     As indicated, the implied enterprise values in the precedent transactions average 1.40x target LTM Revenue. Based on an analysis of the precedent transactions, there is a close correlation between a target’s revenue multiple and its EBITDA margin. In general, companies with higher EBITDA margins will have higher revenue multiples, as EBITDA is an indication of a company’s ability to generate cash from revenues. If Suntron’s LTM Adjusted EBITDA margin was close to the average LTM EBITDA margin of the targets, 1.40x LTM Revenue would be an adequate multiple to use when determining equity value. However, because Suntron’s LTM Adjusted EBITDA margin was significantly below that of the targets in the selected precedent transactions on average, the Filing Persons adjusted the multiple down from the average to a multiple more appropriate for Suntron based on its lower LTM Adjusted EBITDA margin. To calculate the appropriate multiple based on the precedent transactions, the Filing Persons determined the relationship between revenue multiple and LTM EBITDA margins using linear regression. Otherwise, to have used a strict average of revenue multiples under these circumstances would have overstated Suntron’s actual value. Described in a different way, a 1.40x multiple of LTM Revenue implies that a company generates an LTM EBITDA margin of 11.5%. Suntron’s LTM Adjusted EBITDA margin was significantly below 11.5%, and, therefore, the Filing Persons deemed it inappropriate to use a 1.40x revenue multiple to value Suntron’s equity based on LTM Revenue.
     To derive the value of Suntron’s equity using the multiple of revenue method, the Filing Persons considered Suntron’s EBITDA margin when determining the appropriate multiple of revenue to use. By plotting the multiples of revenue as a function of EBITDA margin for the indicated precedent transactions, the Filing Persons determined that the relationship between the two variables can be expressed by an equation, derived by linear regression as set out in the chart graphic below:

     To calculate implied price per Share based on an LTM Revenue multiple, the Filing Persons divided the implied equity value of Suntron (as calculated using the LTM Revenue multiples) by the number of fully diluted shares outstanding for the period ended July 1, 2007 at each individual valuation (calculated using the treasury stock method).

     Using the calculations for Suntron’s LTM Adjusted EBITDA, the LTM Revenue multiple for the Solectron Corp./Flextronics International Ltd. transaction, and assumptions for an LTM Revenue multiple in the linear regression above, the Filing Persons calculated the per Share value of Suntron based on revenue multiple analysis, as it relates to precedent transactions, as follows:

     The Filing Persons allowed for variances in assumptions by paying a 43.6% premium to the mean value per Share of $0.80 as calculated. Including this premium, the Filing Persons arrived at a value of $1.15 per Share.
     The market price and relative lack of liquidity for the Shares, and the liquidity that will be realized by the Unaffiliated Stockholders from the Merger. The Filing Persons believe that the liquidity that would result from the Merger would be beneficial to the Unaffiliated Stockholders of Suntron because the Filing Persons’ ownership of approximately 90.1% of the outstanding Shares (1) results in an extremely small public float that limits the amount of trading in the Shares and (2) decreases the likelihood that a proposal to acquire the Shares by an independent entity could succeed without the consent of the Filing Persons. The Merger will provide consideration to the Unaffiliated Stockholders entirely in cash.
     Earnings multiple valuation. The Filing Persons elected not to use this method of valuation as Suntron has generated negative net income, even on an adjusted basis, for the CY 2006A and LTM periods. Although Suntron has forecasted positive adjusted net income for CY 2007E, the adjusted net income has been deemed by the Filing Persons to be so low that the analysis would prove inconclusive.
     Liquidation value analysis; going concern value analysis. The Filing Persons did not consider the Merger Price as compared to any implied liquidation value because it was not contemplated that Suntron be liquidated, whether or not the Merger was completed. Moreover, liquidation value analysis does not take into account any value that may be attributed to a company’s ability to attract new business. The liquidation value analysis was not performed because the Filing Persons believed such an analysis would yield an amount that is less than Suntron’s value as a going concern, because it does not appropriately take into account the value attributable to the company’s intangible assets, including its goodwill and customer base. A substantial amount of Suntron’s inventory is unique to a particular customer’s order, and there are limited alternative uses or markets for this inventory beyond the products Suntron manufactures for its customers. Accordingly, the Filing Persons believe that under a liquidation value analysis this inventory would have significantly less value than if Suntron were assumed to be purchased as a going concern with its customer relationships remaining intact. While the Filing Persons do not believe there is a single method of determining going concern value, the Filing Persons believe that the financial analysis they performed in their totality are reflective of Suntron’s going concern value.
     Discounted cash flow analysis. The Filing Persons did not consider using discounted cash flow analysis to calculate the equity value of the company because Suntron management has not prepared long-term projections necessary to perform such an analysis.
     Lack of third party offers. Thayer-Blum did not intend to sell their controlling interest in Suntron and, consequently, did not seek a third party buyer for Suntron. Given Thayer-Blum’s desire to retain its investments in Suntron, it is unlikely that finding a third party buyer for Suntron was a realistic option for the Unaffiliated Stockholders. The Filing Persons considered the absence of a third party buyer as a realistic alternative to support the fairness of the Merger to the Unaffiliated Stockholders, because the proposed Merger was the only likely source of prompt liquidity for the Shares available to all of the Unaffiliated Stockholders. The Filing Persons believe that efforts to “shop” Suntron would entail substantial investments of time and resources and detract from management’s focus on Suntron’s business. Furthermore, the Filing Persons believe such actions would disrupt and discourage Suntron’s employees and jeopardize relationships with Suntron’s customers and suppliers.
•     Procedural fairness. The Filing Persons believe that the Merger is procedurally fair to the Unaffiliated Stockholders. In making such determination the Filing Persons considered the following factors:
•     Approval of security holders. Because the Merger is being effected as a short-form merger pursuant to Section 253 of the DGCL, the Merger does not require approval by Suntron’s stockholders.
•     Approval of the board of directors of Suntron. Because the Merger is being effected as a short-form merger pursuant to Section 253 of the DGCL, the Merger does not require approval by Suntron’s Board of Directors.
•     Unaffiliated representative. No representative was engaged to act on behalf of the Unaffiliated Stockholders.
     Notwithstanding the foregoing factors, the Filing Persons believe that the Merger is procedurally fair to the Unaffiliated Stockholders because the Unaffiliated Stockholders will be entitled to exercise appraisal rights to have determined and to receive a court-determined fair value for their Shares under Section 262 of the DGCL (see Item 4(d), “Terms of the Transaction - Appraisal Rights”) and because the Filing Persons are providing advance notice of the Merger. Furthermore, the Filing Persons believe that they have disclosed fully the relevant information to permit the Unaffiliated Stockholders to determine whether to accept the Merger Price or to seek appraisal for their Shares. Additionally, the Merger is intended to comply with Section 253 of the DGCL, which prescribes procedures for “short-form” mergers.

Table of Contents

     The Filing Persons have considered all of the foregoing factors and related analyses prepared by the Filing Persons as a whole to support their belief that the Merger is substantively and procedurally fair to the Unaffiliated Stockholders.
     In addition to the foregoing factors and analyses that support the Filing Persons’ belief that the Merger is procedurally and substantively fair to the Unaffiliated Stockholders, the Filing Persons have considered the following five factors:
    No future participation in the prospects of Suntron. Following the consummation of the Merger, the Unaffiliated Stockholders will cease to participate in the future earnings or growth, if any, of Suntron, or benefit from an increase, if any, in the value of their holdings in Suntron.
 
    Conflicts of interest. The interests of the Filing Persons in determining the Merger Price are adverse to the interests of the Unaffiliated Stockholders and the fact that certain officers and directors of Suntron may have actual or potential conflicts of interest in connection with the Merger as disclosed herein.
 
    No opportunity for Suntron’s Board of Directors or the Unaffiliated Stockholders to vote on the Merger. Because the Merger is being effected pursuant to a short-form merger under Section 253 of the DGCL and consequently does not require approval by Suntron’s Board of Directors or Suntron’s stockholders (other than the Filing Persons), neither Suntron’s Board of Directors nor the Unaffiliated Stockholders will have the opportunity to vote on the Merger.
 
    No special committee representing the Unaffiliated Stockholders’ interests. Suntron’s Board of Directors did not establish a special committee consisting of non-management, independent directors for the purpose of representing solely the interests of the Unaffiliated Stockholders and retaining independent advisers to assist with the evaluation of strategic alternatives, including the Merger.
 
    No fairness opinion. The Filing Persons did not engage any third parties to perform any financial analyses of, or prepare any reports, opinions, or appraisals concerning the Merger or value of the Shares.
     After having given these additional five factors due consideration, the Filing Persons have concluded that none of these factors, alone or in the aggregate, is significant enough to outweigh the factors and analyses that the Filing Persons have considered to support their belief that the Merger is substantively and procedurally fair to the Unaffiliated Stockholders.
     In view of the number and wide variety of factors considered in connection with making a determination as to the fairness of the Merger to the Unaffiliated Stockholders, and the complexity of these matters, the Filing Persons did not find it practicable to, nor did they attempt to, quantify, rank, or otherwise assign relative weights to the specific factors they considered. Moreover, the Filing Persons have not undertaken to make any specific determination or assign any particular weight to any single factor, but have conducted an overall analysis of the factors described above.
     The Filing Persons have not considered any factors, other than as stated above, regarding the fairness of the Merger to the Unaffiliated Stockholders, as it is their view that the factors they considered provided a reasonable basis to form their belief.
     Specifically, in forming their belief as to the fairness of the Merger to the Unaffiliated Stockholders, the Filing Persons did not consider the purchase prices paid by them for past purchases of Shares because Suntron’s financial condition has materially changed since such purchases were made.

19


Table of Contents

     In addition, although the Filing Persons considered current and historical market prices for the Shares, the Filing Persons gave greater weight to other factors. The Filing Persons believe that historical market prices do not reflect Suntron’s current financial condition, which has changed over the last several years. The Filing Persons believe that market prices for the Shares immediately prior to the public announcement of the Merger are not indicative of the fair value of the Shares. The trading volumes at that time were extremely low, and the Filing Persons believe that most stockholders would not have been able to sell their Shares at those prices due to the general lack of liquidity for the Shares, whereas the Merger would provide liquidity for all the Unaffiliated Stockholders. The Filing Persons believe that any trades at that time did not reflect the measure of the fair or intrinsic value of the Shares because of such low trading activity, but instead indicate that the low volume of interest and trading in the Shares results in an inefficient market for the Shares. Additionally, the Filing Persons believe that the market prices are not an accurate indicator because Suntron’s Shares are only sporadically traded with an average daily trading volume of 7,259 Shares for the three-month period ended October 2, 2007. Consequently, the Filing Persons believe that the sale by any stockholder of Suntron of any significant number of Shares would likely result in a correspondingly significant reduction in the market price of the Shares.
REPORTS, OPINIONS, APPRAISALS, AND NEGOTIATIONS
     The Filing Persons have not engaged any third parties to perform any financial analysis of, or prepare any reports, opinions, or appraisals concerning the Merger or value of the Shares and, accordingly, the Filing Persons have not received any report, opinion, or appraisal from an outside party relating to the fairness of the Merger Price being offered to the Unaffiliated Stockholders or the fairness of the Merger to the Filing Persons or to the Unaffiliated Stockholders.

    each share of SUNN Acquisition’s capital stock issued and outstanding immediately prior to the Effective Date will be converted into one validly issued, fully paid, and nonassessable share of common stock of Suntron as the surviving corporation of the Merger. As a result of the Merger, the SUNN Acquisition Stockholders will own all of the outstanding equity interests in Suntron.
     Under the DGCL, because SUNN Acquisition will hold at least 90% of the outstanding Shares prior to the Merger, SUNN Acquisition will have the power to effect the Merger without a vote of Suntron’s Board of Directors or the Unaffiliated Stockholders. SUNN Acquisition intends to take all necessary and appropriate action to cause the Merger to become effective on the Effective Date, without a meeting or consent of Suntron’s Board of Directors or the Unaffiliated Stockholders. The Merger Price payable to the Unaffiliated Stockholders is $1.15 per Share in cash, without interest. The reasons for the Merger are set out in “Special Factors—Purposes, Alternatives, Reasons, and Effects of the Merger—Reasons.”
     Upon completion of the Merger, in order to receive the cash Merger Price of $1.15 per Share, without interest, each stockholder or a duly authorized representative must (1) deliver a Letter of Transmittal, appropriately completed and executed, to the Paying Agent at 350 Indiana Street, Suite 800, Golden, Colorado 80401, Attn: Sean Mclimans, and (2) surrender such Shares by delivering the stock certificate or certificates that, prior to the Merger, had evidenced such Shares to the Paying Agent, as set forth in a Notice of Merger and Appraisal Rights and Letter of Transmittal, which will be mailed to stockholders of record within 10 calendar days of the Effective Date. Stockholders are encouraged to read the Notice of Merger and Appraisal Rights and Letter of Transmittal carefully when received. Delivery of an executed Letter of Transmittal shall constitute a waiver of statutory appraisal rights.
     The Merger will be accounted for as a reorganization of entities under the common control of Thayer-Blum.

     For federal income tax purposes generally, the receipt of the cash consideration by holders of the Shares pursuant to the Merger will be a taxable sale of the holders’ Shares. See “Special Factors—Purposes, Alternatives, Reasons, and Effects of the Merger—Effects—Certain Federal Income Tax Consequences of the Merger.”
     (c) Different Terms. Stockholders of Suntron will be treated as described in Item 4(a) “Terms of the Transaction—Material Terms.”
     (d) Appraisal Rights. Under the DGCL, record holders of Shares who follow the procedures set forth in Section 262 will be entitled to have their Shares appraised by the Court of Chancery of the State of Delaware and to receive payment of the fair value of the Shares, together with interest, if any, as determined by such court. The fair value as determined by the Delaware court is exclusive of any element of value arising from the accomplishment or expectation of the Merger. The following is a summary of certain of the provisions of Section 262 of the DGCL and is qualified in its entirety by reference to the full text of Section 262, a copy of which is attached hereto as Exhibit (f).
     Notice of the Effective Date and the availability of appraisal rights under Section 262 (the “Merger Notice”) will be mailed to record holders of the Shares by Suntron, as the surviving corporation in the Merger, within 10 calendar days after the Effective Date and should be carefully reviewed by the Unaffiliated Stockholders. Any Unaffiliated Stockholder entitled to appraisal rights will have the right, within 20 days after the date of mailing of the Merger Notice, to demand in writing from Suntron an appraisal of his or her Shares. Such demand will be sufficient if it reasonably informs Suntron of the identity of the stockholder and that the stockholder intends to demand an appraisal of the fair value of his or her Shares. Failure to make such a timely demand would foreclose a stockholder’s right to appraisal.
     Only a holder of record of Shares is entitled to assert appraisal rights for the Shares registered in that holder’s name. A demand for appraisal should be executed by or on behalf of the holder of record fully and correctly, as the holder’s name appears on the stock certificates. Holders of Shares who hold their shares in brokerage accounts or other nominee forms and wish to exercise appraisal rights should consult with their brokers to determine the appropriate procedures for the making of a demand for appraisal by such nominee. All written demands for appraisal of Shares should be sent or delivered to Thomas B. Sabol, at Suntron’s offices at 2401 West Grandview Road, Phoenix, Arizona 85023.
     If the Shares are owned of record in a fiduciary capacity, such as by a trustee, guardian, or custodian, execution of the demand should be made in that capacity, and if the Shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all joint owners. An authorized agent, including one or more joint owners, may execute a demand for appraisal on behalf of a holder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, the agent is agent for such owner or owners.
     A record holder such as a broker holding Shares as nominee for several beneficial owners may exercise appraisal rights with respect to the Shares held for one or more beneficial owners while not exercising such rights with respect to the Shares held for other beneficial owners; in such case, the written demand should set forth the number of Shares as to which appraisal is sought and where no number of Shares is expressly mentioned the demand will be presumed to cover all Shares held in the name of the record owner.
     Within 120 calendar days after the Effective Date, Suntron, or any stockholder entitled to appraisal rights under Section 262 and who has complied with the foregoing procedures, may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery demanding a determination of the fair value of the Shares of all such stockholders. Suntron is not under any obligation, and has no present intention, to file a petition with respect to the appraisal of the fair value of the Shares. Accordingly, it is the obligation of the stockholders to initiate all necessary action to perfect their appraisal rights within the time frame prescribed in Section 262. If a stockholder files a petition, a copy of such petition must be served on Suntron.

24


Table of Contents

     Within 120 calendar days after the Effective Date, any stockholder of record who has complied with the requirements for exercise of appraisal rights, assuming that appraisal rights are available, will be entitled, upon written request, to receive from Suntron a statement setting forth the aggregate number of Shares with respect to which demands for appraisal have been received and the aggregate number of holders of such Shares. Such statement must be mailed within 10 calendar days after a written request therefor has been received by Suntron or within 10 calendar days after the expiration of the period for the delivery of demands for appraisal, whichever is later.
     If a petition for an appraisal is timely filed and a copy is served upon Suntron, Suntron will then be obligated within 20 days to file with the Delaware Register in Chancery a duly verified list containing the names and addresses of all stockholders who have demanded an appraisal of their Shares and with whom agreements as to the value of such Shares have not been reached. After notice to those stockholders as required by the Court, the Delaware Court of Chancery is empowered to conduct a hearing on the petition to determine those stockholders who have complied with Section 262 and who have become entitled to appraisal rights. After a hearing on such petition, the Delaware Court of Chancery will determine the stockholders entitled to appraisal rights and will appraise the fair value of the Shares, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with interest, if any, to be paid upon the amount determined to be the fair value. Holders considering seeking appraisal should be aware that the fair value of their Shares as determined under Section 262 could be more than, the same as, or less than the amount per Share that they would otherwise receive if they did not seek appraisal of their Shares. The Delaware Supreme Court has stated that “proof of value by any techniques or methods that are generally considered acceptable in the financial community and otherwise admissible in court” should be considered in the appraisal proceedings. In addition, Delaware courts have decided that the statutory appraisal remedy, depending on factual circumstances, may or may not be a dissenter’s exclusive remedy. The Court will also determine the amount of interest, if any, to be paid upon the amounts to be received by persons whose Shares have been appraised. The costs of the action may be determined by the Court and taxed upon the parties as the Court deems equitable. The Court may also order that all or a portion of the expenses incurred by any holder of Shares in connection with an appraisal, including, without limitation, reasonable attorneys’ fees and the fees and expenses of experts used in the appraisal proceeding, be charged pro rata against the value of all the Shares entitled to appraisal.
     The Court may require stockholders who have demanded an appraisal and who hold Shares represented by certificates to submit their certificates to the Court for notation thereon of the pendency of the appraisal proceedings. If any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.
     Any stockholder who has duly demanded an appraisal in compliance with Section 262 will not, after the Effective Date, be entitled to vote the Shares subject to such demand for any purpose or be entitled to the payment of dividends or other distributions on those Shares (except dividends or other distributions payable to holders of record of Shares as of a date prior to the Effective Date).
     If any stockholder who demands appraisal of Shares under Section 262 fails to perfect, or effectively withdraws or loses, the right to appraisal, as provided in the DGCL, the Shares of such holder will be converted into the right to receive the Merger Price per Share, without interest. A stockholder will fail to perfect, or effectively lose, the right to appraisal if no petition is filed within 120 calendar days after the Effective Date. A stockholder may withdraw a demand for appraisal by delivering to Suntron a written withdrawal of the demand for appraisal and acceptance of the Merger Price, except that any such attempt to withdraw made more than 60 calendar days after the Effective Date will require the written approval of Suntron. Once a petition for appraisal has been filed, such appraisal proceeding may not be dismissed as to any stockholder without the approval of the Court.
     For federal income tax purposes, stockholders who receive cash for their Shares upon exercise of their statutory right of dissent will realize taxable gain or loss. See “Special Factors—Purposes, Alternatives, Reasons, and Effects of the Merger—Effects—Certain Federal Income Tax Consequences of the Merger.”

     (e) Provisions for Unaffiliated Security Holders. None of the Filing Persons intend to grant the Unaffiliated Stockholders special access to Suntron’s records in connection with the Merger.

Item 5. Past Contacts, Transactions, Negotiations and Agreements
     (a) Transactions.
     Thayer-Blum Management and Consulting Agreement
     In 2002, Suntron entered into a management and consulting agreement with Thayer-Blum (the “Consulting Agreement”). The services provided under the Consulting Agreement consist of management fees related to corporate development activities and consulting services for strategic and operational issues. Pursuant to the Consulting Agreement, Suntron pays a fixed management and consulting fee of $750,000 per year to affiliates of Thayer-Blum.
     In addition, Suntron has agreed to pay Thayer-Blum additional incentive compensation with respect to (1) each acquisition of a business operation by Suntron introduced or negotiated by Thayer-Blum or any of its affiliates, (2) each disposition of a business operation by Suntron negotiated by Thayer-Blum or any of its affiliates, or (3) each public equity financing consummated by Suntron and negotiated by Thayer-Blum or any of its affiliates.
     SUNN Acquisition has entered into a management and consulting agreement with Thayer-Blum on substantially the same terms as the Consulting Agreement, which will become effective upon the closing of the Merger and will supersede the Consulting Agreement.
     Participation Agreement
     On August 19, 2005, Suntron’s former lenders agreed to amend the credit agreement with Suntron to permit Thayer Equity, an affiliate of Thayer-Blum, to enter into a participation agreement with Suntron’s lenders. Under the participation agreement, Thayer Equity made a $5.0 million cash payment to the lenders, and the lenders agreed to pay interest to Thayer Equity at the same rate that the lenders charged Suntron under the credit agreement. Effective on January 31, 2006, the participation agreement was amended, and Thayer Equity provide another $5.0 million cash payment to Suntron’s lenders on the same terms.
     On March 30, 2006, Suntron terminated this credit agreement and entered into new debt financing agreements. As a result, the participation agreement between Thayer Equity and the lenders was terminated.
     Note Purchase Agreement
     On March 30, 2006, Suntron issued a $10.0 million subordinated note (the “Second Lien Note”) to Thayer Equity. The Second Lien Note is collateralized by a second priority interest in substantially all of the collateral under Suntron’s credit agreement with U.S. Bank National Association (the “US Bank Credit

26


Table of Contents

Agreement”). The Second Lien Note is subordinated in right of payment to the obligations under the US Bank Credit Agreement and has a maturity date that is 45 days after the maturity date of the US Bank Credit Agreement. The Second Lien Note bears interest at an annual rate of 16.0%, payable quarterly in kind (or payable in cash with written approval from US Bank). Suntron has the option to prepay the Second Lien Note with a redemption penalty up to 3.0% of the then outstanding principal balance. If the Second Lien Note is paid on the maturity date, a fee equal to 2.0% of the then outstanding principal balance is due.
     In connection with the Merger, SUNN Acquisition intends to borrow the funds necessary to pay the Merger Price and all related expenses and fees from Thayer Equity and U.S. Bank National Association. The funding to be provided by Thayer Equity is expected to be on terms substantially the same as the terms of the Second Lien Note. Completion of the Merger is subject to completion of the financing and the consent of Suntron’s lenders.
     Maintenance Agreement
     In connection with the US Bank Credit Agreement, Thayer Equity entered into a maintenance agreement (the “Maintenance Agreement”) with US Bank that requires Thayer Equity to make up to an additional $5.0 million of subordinated loans to Suntron if the fixed charge coverage ratio falls below a prescribed level. Loans pursuant to this Maintenance Agreement would have similar terms as the Second Lien Note; however, the interest rate on such additional loans cannot exceed 18.0%.
     Contribution Agreement
     The Contribution Agreement by and among SUNN Acquisition and the SUNN Acquisition Stockholders (as hereinafter defined) is described below in Section (e) of this Item 5.
     References to and descriptions of the Consulting Agreement, the Second Lien Note, and the Maintenance Agreement as set forth herein are qualified in their entirety by reference to the copies of the Consulting Agreement, the Second Lien Note, and the Maintenance Agreement.

     (b) Significant Corporate Events.

     (c) Negotiations or Contacts. During 2005, one of Suntron’s competitors approached representatives of Blum Capital Partners, L.P. (“Blum Capital Partners”) to express their interest in possibly acquiring 100% of Suntron’s stock. Suntron’s board of directors formed a committee to pursue discussions with the competitor. While preliminary discussions were held, these discussions were discontinued as no formal offer was forthcoming and none of Suntron, Thayer-Blum, Blum Capital Partners or any other member of Thayer-Blum has received a firm offer regarding this possible acquisition or any third party acquisition. Other than as described in this Schedule 13E-3, there have been no other negotiations or material contacts that occurred during the past two years concerning the matters referred to in paragraph (b) of this Item 5 between (i) any affiliates of Suntron or (ii) Suntron or any of its affiliates and any person not affiliated with Suntron who would have a direct interest in such matters.
     (e) Agreements Involving the Subject Company’s Securities.

     Contribution Agreement
     A Contribution Agreement, dated October 3, 2007 (the “Contribution Agreement”), was entered into by and among Thayer-Blum, Circuit Test Intl Grit LP, Allen S Braswell Jr LP, Braswell Gifting Trust, Allee L Braswell & Allen S Braswell Jr Jt Ten, Allen S.

This Contribution Agreement governs the ownership structure of and contribution of Shares to SUNN Acquisition. It also provides that the SUNN Acquisition Stockholders will execute and deliver a Stockholder’s Agreement after completion of the Merger that will govern the rights of the SUNN Acquisition Stockholders, including customary corporate governance provisions, restrictions on the transfer of shares, tag-along and drag-along rights, and registration rights. This Contribution Agreement is incorporated by reference to Exhibit 99.2 of Schedule 13D filed by the Filing Persons and certain other persons on October 3, 2007.
     In connection with the Contribution Agreement, the members of Thayer-Blum (the “TBF Members”) have entered into a Letter Agreement that governs the relationship of the TBF Members after the completion of the Merger. The Letter Agreement provides that subsequent to the Merger, the TBF Members will take all necessary action to dissolve Thayer-Blum and distribute the shares of Suntron (as the surviving corporation to the Merger) held by Thayer-Blum to the TBF Members in proportion to their ownership of Thayer-Blum. In addition, the Letter Agreement provides that concurrently with the dissolution of Thayer-Blum, the TBF Members and the other SUNN Acquisition Stockholders will enter into a Stockholders’ Agreement that will govern the rights of the TBF Members and the other SUNN Acquisition Stockholders, including customary corporate governance provisions, restrictions on the transfer of shares, tag-along and drag-along rights, and registration rights. The Letter Agreement also provides that all fees and expenses incurred in connection with the transactions described therein shall be reimbursed by Suntron following the Merger.
     Registration Rights Agreement
     Pursuant to the Registration Rights Agreement between Suntron and Thayer-Blum (the “Rights Agreement”), Thayer-Blum has the right to require Suntron to register Thayer-Blum’s resale of shares of Suntron common stock under the Securities Act. Thayer-Blum, or a permitted transferee, must request that the registration include at least 375,000 shares of Suntron common stock. If Suntron proposes to register an offering of its securities under the Securities Act, either for its own account or the account of others, Thayer-Blum will be entitled to notice of such registration and to include its shares in such registration, and no minimum amount must be included in such case. The underwriters for any such registration will have the right to limit the number of such shares included in such registration, subject to certain conditions.
     Thayer-Blum may transfer its rights under the Rights Agreement to its members. Thayer-Blum may also transfer Suntron common stock, and the related rights under the Rights Agreement, to any person in a transaction exempt from the registration requirement of the Securities Act. Generally, Suntron is required to pay all costs and expenses in connection with its obligations under the Rights Agreement. The Rights Agreement will terminate on the earlier of (1) March 30, 2010 and (2) such time as all Suntron shares received by Thayer-Blum have been sold pursuant to an effective registration statement under the Securities Act. In addition, pursuant to the Contribution Agreement and the Letter Agreement described in this Item 5(e), the Rights Agreement shall terminate upon the execution of the Stockholders’ Agreement described therein.

The Filing Persons intend to continue to evaluate the business and operations of Suntron with a view to maximizing Suntron’s potential, and it will take such actions as it deems appropriate under the circumstances and market conditions then existing.

For additional information see Item 4 “Terms of the Transaction” and “Special Factors—Purposes, Alternatives, Reasons, and Effects of the Merger—Effects.”
     The Filing Persons do not currently have any commitment or agreement and are not currently negotiating for the sale of any of Suntron’s businesses. Additionally, the Filing Persons do not currently contemplate any material change in the composition of Suntron’s current management, except that the Filing Persons may appoint a new Board of Directors for Suntron, a majority of the members of which will be representatives of the Filing Persons.
     Except as otherwise described in this Schedule 13E-3, Suntron has not, and the Filing Persons have not, as of the date of this Schedule 13E-3, approved any specific plans or proposals for:
    any extraordinary corporate transaction involving Suntron after the completion of the Merger;
    any sale or transfer of a material amount of assets currently held by Suntron after the completion of the Merger;

     (a) Securities Ownership. On the Effective Date, immediately prior to the Merger, SUNN Acquisition is expected to be the owner of 24,892,751 Shares, representing approximately 90.1% of the outstanding Shares. Because Thayer-Blum and its affiliates hold an approximately 98.75% equity interest in SUNN Acquisition, Thayer-Blum may also be deemed to be the beneficial owner of these Shares. Details regarding the ownership of Shares by the persons named on Schedule I to this Schedule 13E-3 are set out thereon.

(a)   Earnings (loss) before interest, taxes, depreciation, and amortization (“EBITDA”) is presented because the Filing Persons believe it is an indicator of a company’s ability to incur and service debt and to fund capital expenditures. An EBITDA-based calculation is also used by Suntron’s lenders in determining compliance with certain financial covenants.
 
(b)   The primary measure of operating performance is net income (loss). EBITDA should not be construed as an alternative to net income (loss), determined in accordance with U.S. generally accepted accounting principles, or GAAP, as an indicator of operating performance, as a measure of liquidity or as an alternative to cash flows from operating activities determined in accordance with GAAP. The presentation of these additional financial performance indicators can be beneficial to investors since they provide an additional perspective from which to evaluate a company. However, in evaluating alternative measures of operating performance, it is important to understand that there are no standards for these calculations. Accordingly, the lack of standards can result in subjective determinations about which items may be excluded from the calculations, as well as the potential for inconsistencies between different companies that have similarly titled alternative measures. For example, as discussed in greater detail under Management’s Discussion and Analysis of Financial Condition and Results of Operations of Suntron’s Form 10-K for its year ended December 31, 2006, the calculation of EBITDA in its credit agreement with US Bank is different than the calculation of EBITDA shown above.
 
(c)   Total invested capital represents total debt plus total stockholders’ equity.
          Recent Financial Performance. Suntron’s unaudited, consolidated financial statements for the nine-month period ended September 30, 2007 indicated that Suntron had net sales of $181.9 million, operating income of $0.3 million, and a net loss of $1.8 million, compared to net sales of $251.5 million, operating loss of $1.4 million, and a net loss of $6.2 million for the nine-month period ended October 1, 2006. Suntron’s total stockholders’ equity was $42.3 million as of September 30, 2007, compared to total stockholders’ equity of $43.6 million as of December 31, 2006.
Item 14. Persons/Assets, Retained, Employed, Compensated or Used
     (a) Solicitations or Recommendations. There are no persons or classes of persons who are directly or indirectly employed, retained, or to be compensated to make solicitations or recommendations in connection with the Merger.
