Common stock

The selling stockholder named in this prospectus supplement is offering 12,000,000 shares of our common stock, par value $0.001 per share. We will not receive any proceeds from the sale of our common stock by the selling stockholder.

Our common stock is listed on the NASDAQ Global Select Market, or the NASDAQ, under the symbol “TTMI.” The last reported sale price of our common stock on NASDAQ on November 11, 2016, was $14.49 per share.

Risk factors

Investing in our common stock involves risks. Before making an investment in our common stock, you should carefully consider, among other factors, the risks described below and elsewhere in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein. Please see “Statement regarding forward-looking statements” on page S-15 of this prospectus supplement. Please also see the risks described in the documents incorporated by reference in this prospectus supplement and the accompanying prospectus, including those identified under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 28, 2015, and in our Quarterly Report on Form 10-Q for the quarterly period ended September 26, 2016. The risks described in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein are not the only ones we face. Additional risks not presently known or that we currently deem immaterial could also materially adversely affect our business, financial condition, results of operations and prospects. Our business, financial condition and results of operations could be materially adversely affected by the materialization of any of these risks. The trading price of our common stock could decline due to the materialization of any of these risks, and you may lose all or part of your investment.

Risks relating to this offering and our common stock

The market price of our common stock may decline after the offering.

The price per share of common stock sold in this offering may be more or less than the market price of our common stock on the date the offering is consummated. If the purchase price is greater than the market price at the time of sale, purchasers may experience an immediate decline in the market value of the common stock purchased in this offering. If the actual purchase price is less than the market price for the shares of common stock, some purchasers in the offering may be inclined to immediately sell shares of common stock to attempt to realize a profit. Any such sales, depending on the volume and timing, could cause the price of our common stock to decline. Additionally, because stock prices generally fluctuate over time, there is no assurance that purchasers of our common stock in the offering will be able to sell shares after the offering at a price that is equal to or greater than the actual purchase price. Purchasers should consider these possibilities in determining whether to purchase shares in the offering and the timing of any sales of shares of common stock.

Our stock price could be extremely volatile, and, as a result, you may not be able to resell your shares at or above the price you paid for them.

Since the beginning of our last fiscal year, the price of our common stock, as reported by the NASDAQ, has ranged from a low of $4.67 on February 5, 2016 to a high of $14.69 on November 7, 2016. In addition, in recent years the stock market in general has been highly volatile. As a result, the market price and trading volume of our common stock is likely to be similarly volatile, and investors in our common stock may experience a decrease, which could be substantial, in the value of their stock, including decreases unrelated to our results of operations or prospects, and could lose part or all of their investment. The price of our common stock could be subject to wide fluctuations in response to a number of factors, including those described elsewhere in this prospectus supplement and the accompanying prospectus and others such as:

S-11

Table of Contents

In the past, securities class action litigation has often been initiated against companies following periods of volatility in their stock price. This type of litigation could result in substantial costs and divert our management’s attention and resources, and could also require us to make substantial payments to satisfy judgments or to settle litigation.

Because we do not expect to pay any cash dividends for the foreseeable future, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.

We have not declared or paid any dividends since 2000 and do not anticipate paying any cash dividends on our common stock in the foreseeable future. Any payment of cash dividends will be at the discretion of our board of directors and will depend on our financial condition, anticipated cash needs, capital requirements, legal requirements, earnings and other factors. Our ability to pay dividends is restricted by the terms of our debt agreements and might be restricted by the terms of any indebtedness that we incur in the future. Consequently, you should not rely on dividends in order to receive a return on your investment. See “Dividend policy.”

Provisions of our corporate governance documents and Delaware Law could make an acquisition of our Company more difficult and may prevent attempts by our stockholders to replace or remove our current management, even if beneficial to our stockholders.

Our certificate of incorporation and bylaws and the Delaware General Corporation Law, or the DGCL, contain provisions that could make it more difficult for a third party to acquire us, even if doing so might be beneficial to our stockholders. These provisions include:

S-12

Table of Contents

In addition, Section 203 of the DGCL may affect the ability of an “interested stockholder” to engage in certain business combinations, for a period of three years following the time that the stockholder becomes an “interested stockholder.”

Because our board of directors is responsible for appointing the members of our management team, these provisions could in turn affect any attempt to replace current members of our management team. As a result, you may lose your ability to sell your stock for a price in excess of the prevailing market price due to these protective measures, and efforts by stockholders to change the direction or management of the Company may be unsuccessful. See “Description of capital stock” in the accompanying prospectus.

A significant portion of our total outstanding shares are restricted from immediate resale but may be sold into the market in the near future. This could cause the market price of our common stock to drop significantly, even if our business is doing well.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock. In connection with this offering, we and the selling stockholder will enter into 90-day lock-up agreements with the underwriters. After the lock-up period, these shares will, however, be freely transferrable pursuant to Rule 144 under the Securities Act, except for shares held by our “affiliates,” who are subject to additional conditions under Rule 144. We have also filed a Form S-8 under the Securities Act to register shares of common stock that we may issue under our equity compensation plans. In addition, the selling stockholder has demand registration rights that could require us in the future to file registration statements in order to sell their common stock. Such sales could be significant. Once we register these shares, they can be freely sold in the public market upon issuance, subject to the lock-up agreements described in the “Underwriting” section of this prospectus supplement. As restrictions on resale end, the market price of our stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them.

Future sales of our common stock or other securities may dilute the value and adversely affect the market price of our common stock.

In the future, we may issue additional equity securities, through public or private offerings, in order to raise additional capital. Pursuant to our certificate of incorporation, our board of directors has the authority, without action by stockholders, to designate and issue preferred stock in one or more series. Our board of directors may also designate the rights, preferences and privileges of each series of preferred stock, any or all of which may be superior to the rights of the common stock. Any such issuance would reduce your influence over matters on which our stockholders vote, would dilute the percentage of ownership interest of existing stockholders and may dilute the per share book value of the common stock. In addition, option holders may exercise their options at a time when we would otherwise be able to obtain additional equity capital on more favorable terms. Any issuances of preferred stock would likely result in your interest being subject to the prior rights of holders of that preferred stock. The market price of our common stock could decline as a result of this offering as well as sales of shares of our common stock made after this offering or the perception that such sales could occur.

Our ability to use net operating loss carryforwards to offset future taxable income for U.S. federal income tax purposes is subject to limitation, and future transfers of shares could cause us to experience an “ownership change” that could further limit our ability to utilize our net operating losses.

Under U.S. federal income tax law, a corporation’s ability to utilize its net operating losses, or NOLs, to offset future taxable income may be significantly limited if it experiences an “ownership change” as defined in

S-13

Table of Contents

Section 382 of the Internal Revenue Code of 1986, as amended, which we refer to as the Code. In general, an ownership change will occur if there is a cumulative change in a corporation’s ownership by “5-percent shareholders” that exceeds 50 percentage points over a rolling three-year period. A corporation that experiences an ownership change will generally be subject to an annual limitation on its pre-ownership change NOLs equal to the value of the corporation immediately before the ownership change, multiplied by the long-term tax-exempt rate (subject to certain adjustments). The annual limitation for a taxable year generally is increased by the amount of any “recognized built-in gains” for such year and the amount of any unused annual limitation in a prior year. As a result of our acquisition of Viasystems, the NOLs acquired were subject to this limitation. If we experience a change in ownership, our NOLs could be further limited.

Use of proceeds

The selling stockholder will receive all of the net proceeds from this offering. We will not receive any of the proceeds from the sale of shares of common stock offered by the selling stockholder. We will, however, bear certain costs associated with the sale of shares by the selling stockholder, other than any underwriting compensation and any costs the selling stockholder has agreed to bear pursuant to the underwriting agreement and the relevant registration rights agreement.

Dividend policy

We have not declared or paid any dividends since 2000 and do not anticipate paying any cash dividends in the foreseeable future. The declaration, amount and payment of any future dividends on shares of our common stock will be at the sole discretion of our board of directors, which may take into account general economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual (including our credit agreements), legal, tax and regulatory restrictions, the implications of the payment of dividends by us to our stockholders or our subsidiaries to us, and any other factors that our board of directors may deem relevant.

Selling stockholder

The percentages of shares owned prior to this offering are based on the 100,393,160 shares of our common stock outstanding as of November 2, 2016. The information regarding shares beneficially owned after this offering assumes the sale of all shares offered by the selling stockholder and that the selling stockholder does not acquire any additional shares. For more information regarding our relationship with the selling stockholder, refer to our most recent Annual Report on Form 10-K and other filings with the SEC that are incorporated by reference into this prospectus supplement.

The amounts and percentage of common stock beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of securities. Under the rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares “voting power,” which includes the power to vote or to direct the voting of such security, or “investment power,” which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Under these rules, more than one person may be deemed a beneficial owner of the same securities and a person may be deemed a beneficial owner of securities as to which he or she has no economic interest. The number of shares of common stock outstanding used in calculating the percentage for each listed person includes the shares of common stock underlying options or warrants held by such person that are exercisable within 60 days after November 2, 2016, but excludes shares of common stock underlying options or warrants held by any other person. The underwriters of this offering have an option to purchase up to 1,800,000 additional shares of common stock from the selling stockholder.

The selling stockholder has not had any material relationship with us or any of our affiliates within the past three years other than as a result of the ownership of our securities, and none of the persons who have control over the selling stockholder has had a material relationship with us or any of our affiliates within the past three years except for Mr. Tang Chung Yen, Tom, who currently serves as a director of the Company and has been a director since April 2010, and as otherwise described in the table below.

Material United States federal income tax

considerations for non-U.S. holders

The following is a general discussion of material U.S. federal income tax considerations with respect to the ownership and disposition of our common stock applicable to a Non-U.S. Holder (as defined below) that purchases such shares in this offering. This summary applies only to a Non-U.S. Holder that holds our common stock as a capital asset (i.e., generally as an investment) within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended, or the Code.

For purposes of this summary, a “Non-U.S. Holder” means a beneficial owner of our common stock (other than an entity treated as a partnership for U.S. federal income tax purposes) that is not, for U.S. federal income tax purposes, any of the following:

This summary is based upon the provisions of the Code, the U.S. Treasury regulations promulgated under the Code and administrative and judicial interpretations of the Code, all as of the date of this prospectus supplement. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those summarized below. We cannot assure you that a change in law, possibly with retroactive application, will not alter significantly the tax considerations that we describe in this prospectus supplement. We have not sought and do not plan to seek any ruling from the U.S. Internal Revenue Service, or the IRS, with respect to statements made and the conclusions reached in the following discussion, and we cannot assure you that the IRS or a court will agree with our statements and conclusions.

This discussion does not address all aspects of U.S. federal income taxation or any aspects of alternative minimum, estate, state, local or non-U.S. taxation. In addition, it does not address any aspects of the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010. It also does not consider any specific facts or circumstances that may apply to particular Non-U.S. Holders that may be subject to special treatment under the U.S. federal income tax laws, including, but not limited to, controlled foreign corporations; expatriates and former long-term residents of the United States; passive foreign investment companies; companies that accumulate earnings to avoid U.S. federal income tax; foreign tax-exempt organizations; “expatriated entities”; companies subject to the “stapled stock” rules; former U.S. citizens or residents and persons who hold or receive the shares of common stock as compensation; and investors in pass-through entities. Non-U.S. Holders should consult their tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them.

If a partnership or any other entity or arrangement taxed as a partnership for U.S. federal income tax purposes is a beneficial owner of our common stock, the treatment of a partner in the partnership will generally depend upon the status of the equity owner of such partnership and the activities of the partnership. Accordingly, partnerships (and entities and arrangements taxed as partnerships) that hold our common stock and partners in such partnerships (or other entities or arrangements taxed as partnerships) are urged to consult their tax advisors regarding the U.S. federal income tax consequences to them of acquiring, owning or disposing of our common stock.

PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE U.S. FEDERAL INCOME TAX CONSEQUENCES TO THEM OF ACQUIRING, OWNING AND DISPOSING OF SHARES OF OUR COMMON STOCK, AS WELL AS THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX CONSIDERATIONS OF ACQUIRING, OWNING AND DISPOSING OF SHARES OF COMMON STOCK.

Dividends

Distributions with respect to our stock (other than certain pro rata distributions of our stock) will be treated as dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Subject to the FATCA discussion below, dividends paid to you generally will be subject to U.S. federal withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty, unless the dividends are effectively connected with a trade or business carried on by the Non-U.S. Holder within the United States (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base maintained by the Non-U.S. Holder).

Dividends that are effectively connected with the conduct of a trade or business by you within the United States (and, where a tax treaty applies, are generally attributable to a U.S. permanent establishment or fixed base) are not subject to the U.S. withholding tax, but instead are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate rates. Certain certification and disclosure requirements including delivery of a properly executed IRS Form W-8ECI (or other applicable form) must be satisfied for effectively connected income to be exempt from withholding. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

If the amount of a distribution exceeds our current and accumulated earnings and profits, such excess first will be treated as a tax-free return of capital to the extent of your adjusted tax basis in our shares, and thereafter will be treated as capital gain that is taxed to you as described below under the heading “—Gain on sale or other disposition of our common stock.” Your adjusted tax basis is generally the purchase price of such shares, reduced by the amount of any such tax-free returns of capital.

If you wish to claim the benefit of an applicable treaty rate to avoid or reduce withholding of U.S. federal income tax and avoid backup withholding, as discussed below, for dividends, then you must (a) provide the withholding agent with a properly completed IRS Form W-8BEN or W-8 BEN-E (or other applicable form) and certify under penalties of perjury that you are not a U.S. person and are eligible for treaty benefits or (b) if our common stock is held through certain foreign intermediaries, satisfy the relevant certification requirements of applicable U.S. Treasury regulations. Special certification and other requirements apply to certain Non-U.S. Holders that act as intermediaries (including partnerships). If you are eligible for a reduced rate of U.S. federal withholding tax under an income tax treaty, you may obtain a refund or credit of any excess amounts withheld by filing an appropriate claim for refund with the IRS. You are encouraged to consult your own tax advisor regarding your possible entitlement to benefits under an income tax treaty.

Gain on sale or other disposition of our common stock

Subject to the backup withholding and FATCA discussion below, you generally will not be subject to U.S. federal income tax or withholding with respect to gain realized on the sale or other taxable disposition of our common stock, unless:

S-22

Table of Contents

If you are an individual described in the first bullet point above, you will be subject to tax on the net gain derived from the sale or other disposition in the same manner as if you were a United States person as defined under the Code. In addition, if you are a foreign corporation described in the first bullet point above, you will be subject to tax on your gain under regular graduated U.S. federal income tax rates and, in addition, may be subject to the branch profits tax equal to 30% of your effectively connected earnings and profits, subject to certain adjustments, or at such lower rate as may be specified by an applicable income tax treaty.

If you are an individual described in the second bullet point above, you will be subject to a flat 30% tax (or such lower rate as may be specified by an applicable income tax treaty between the United States and such Non-U.S. Holder’s country of residence) on the net gain derived from the sale, which may be offset by certain U.S. source capital losses, if any (even though you are not considered a resident of the United States), provided that you have timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, generally, we will be a USRPHC if the fair market value of our United States real property interests equals or exceeds 50% of the sum of the fair market values of our worldwide (domestic and foreign) real property interests and other assets used or held for use in a trade or business, all as determined under applicable U.S. Treasury regulations. We believe that we are not currently and do not expect to become a USRPHC. However, because the determination of whether we are a USRPHC depends on the fair market value of our United States real property interests relative to the fair market value of our other business assets, there can be no assurance that we will not become a USRPHC in the future. Even if we become a USRPHC, however, as long as our common stock is regularly traded on an established securities market, such common stock will be treated as a United States real property interest only if the Non-U.S. Holder actually or constructively held more than five percent of our common stock at any time during the shorter of the five-year period preceding the disposition or the Non-U.S. Holder’s holding period for our common stock. You should be aware that no assurance can be given that our shares will be regularly traded when a Non-U.S. Holder sells its shares of our common stock.

Information reporting and backup withholding tax

The applicable reporting agent must annually report to the IRS and to each Non-U.S. Holder any dividend income that is subject to U.S. federal withholding tax, or that is exempt from such withholding tax pursuant to an income tax treaty. Under tax treaties or other agreements, the IRS may make this information available to the tax authorities in the country in which you are resident.

In addition, you may be subject to additional information reporting requirements and backup withholding tax (currently at a rate of 28%) with respect to distributions paid on, and the proceeds of disposition of, shares of our common stock, unless, generally, you certify under penalties of perjury (usually on IRS Form W-8BEN or W-8 BEN-E) that you are not a United States person as defined under the Code or you otherwise establish an exemption. Additional rules relating to information reporting requirements and backup withholding tax with respect to payments of the proceeds from the disposition of shares of our common stock are as follows:

S-23

Table of Contents

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding tax rules may be allowed as a refund or a credit against your U.S. federal income tax liability, provided the required information is timely furnished by you to the IRS. Non-U.S. Holders should consult their tax advisors on the application of information reporting and backup withholding to them (including upon their disposition of our common stock).

Additional withholding considerations

Pursuant to legislation commonly known as the Foreign Account Tax Compliance Act, or FATCA, foreign financial institutions (which include most foreign hedge funds, private equity funds, mutual funds, securitization vehicles and other investment vehicles) and certain other foreign entities must comply with information reporting rules with respect to their U.S. account holders and investors or pay a withholding tax on U.S. source payments made to them (whether received as a beneficial owner or as an intermediary for another party). More specifically, a foreign financial institution or other foreign entity that does not comply with the FATCA reporting requirements will generally be subject to a 30% withholding tax with respect to any “withholdable payments”. For this purpose, withholdable payments include generally U.S. source payments otherwise subject to nonresident withholding tax (e.g., U.S. source dividends) and also include the entire gross proceeds from the sale of any equity or debt instruments of U.S. issuers. The FATCA withholding tax applies even if the payment would otherwise not be subject to U.S. nonresident withholding tax (e.g., capital gain). U.S. Treasury regulations and IRS guidance defer this withholding obligation for gross proceeds from dispositions of U.S. common stock until after December 31, 2018.

Potential investors are urged to consult with their own tax advisors regarding the effect, if any, of the FATCA provisions to them based on their particular circumstances.

Underwriting

The selling stockholder is offering the shares of common stock described in this prospectus through a number of underwriters. J.P. Morgan Securities LLC is acting as sole book-running manager of the offering. We and the selling stockholder have entered into an underwriting agreement with the underwriters. Subject to the terms and conditions of the underwriting agreement, the selling stockholder has agreed to sell to the underwriters, and each underwriter has severally agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus, the number of shares of common stock listed next to its name in the following table:

The underwriters are committed to purchase all the shares of common stock offered by the selling stockholder if they purchase any shares. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

The underwriters propose to offer the common stock directly to the public at the public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $0.276 per share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $0.092 per share from the public offering price. After the public offering of the shares, the offering price and other selling terms may be changed by the underwriters.

The underwriters have an option to buy up to 1,800,000 additional shares of common stock from the selling stockholder. The underwriters have 30 days from the date of this prospectus to exercise this option. If any shares are purchased with this option, the underwriters will purchase shares in approximately the same proportion as shown in the table above. If any additional shares of common stock are purchased, the underwriters will offer the additional shares on the same terms as those on which the shares are being offered.

The underwriting fee is equal to the public offering price per share of common stock less the amount paid by the underwriters to the selling stockholder per share of common stock. The underwriting fee is $0.48875 per share. The following table shows the per share and total underwriting discounts and commissions to be paid to the underwriters by the selling stockholder assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

We estimate that the expenses of this offering payable by us, including registration, filing and listing fees, printing fees and legal and accounting expenses, but excluding the underwriting discounts and commissions,

will be approximately $535,000. We have agreed to reimburse the underwriters for certain expenses in connection with this offering in an amount not exceeding $20,000.

A prospectus in electronic format may be made available on the web sites maintained by one or more underwriters, or selling group members, if any, participating in the offering. The underwriters may agree to allocate a number of shares to underwriters and selling group members for sale to their online brokerage account holders. Internet distributions will be allocated by the representative to underwriters and selling group members that may make Internet distributions on the same basis as other allocations.

We have agreed that we will not (i) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise transfer or dispose of, directly or indirectly, or file with the SEC a registration statement under the Securities Act relating to, any shares of our common stock or securities convertible into or exchangeable or exercisable for any shares of our common stock, subject to certain exceptions, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing, or (ii) enter into any swap or other arrangement that transfers all or a portion of the economic consequences associated with the ownership of any shares of common stock or any such other securities (regardless of whether any of these transactions are to be settled by the delivery of shares of common stock or such other securities, in cash or otherwise), in each case without the prior written consent of J.P. Morgan Securities LLC for a period of 90 days after the date of this prospectus.

The selling stockholder has entered into a lock-up agreement with the underwriters prior to the commencement of this offering pursuant to which it, with limited exceptions, for a period of 90 days after the date of this prospectus, may not, without the prior written consent of J.P. Morgan Securities LLC, (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock or any securities convertible into or exercisable or exchangeable for our common stock (including, without limitation, common stock or such other securities which may be deemed to be beneficially owned by such directors, executive officers, managers and members in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the common stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common stock or such other securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any shares of our common stock or any security convertible into or exercisable or exchangeable for our common stock.

We and the selling stockholder have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

Our common stock is listed on the NASDAQ Global Select Market under the symbol “TTMI”.

In connection with this offering, the underwriters may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of the common stock, which involves the sale by the underwriters of a greater number of shares of common stock than they are required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriters’ over-allotment option referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriters may close out any covered short position either by exercising their option to purchase additional shares, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriters will consider, among other things, the price of shares available for purchase in

S-26

Table of Contents

the open market compared to the price at which the underwriters may purchase shares through the option to purchase additional shares. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriters create a naked short position, they will purchase shares in the open market to cover the position.

The underwriters have advised us that, pursuant to Regulation M, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock, including the imposition of penalty bids. This means that if the representative of the underwriters purchases common stock in the open market in stabilizing transactions or to cover short sales, the representative can require the underwriters that sold those shares as part of this offering to repay the underwriting discount received by them.

These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriters commence these activities, they may discontinue them at any time. The underwriters may carry out these transactions on the NASDAQ, in the over-the-counter market or otherwise.

In addition, in connection with this offering certain of the underwriters (and selling group members) may engage in passive market making transactions in our common stock on the NASDAQ prior to the pricing and completion of this offering. Passive market making consists of displaying bids on the NASDAQ no higher than the bid prices of independent market makers and making purchases at prices no higher than these independent bids and effected in response to order flow. Net purchases by a passive market maker on each day are generally limited to a specified percentage of the passive market maker’s average daily trading volume in the common stock during a specified period and must be discontinued when such limit is reached. Passive market making may cause the price of our common stock to be higher than the price that otherwise would exist in the open market in the absence of these transactions. If passive market making is commenced, it may be discontinued at any time.

Other than in the United States, no action has been taken by us or the underwriters that would permit a public offering of the securities offered by this prospectus in any jurisdiction where action for that purpose is required. The securities offered by this prospectus may not be offered or sold, directly or indirectly, nor may this prospectus or any other offering material or advertisements in connection with the offer and sale of any such securities be distributed or published in any jurisdiction, except under circumstances that will result in compliance with the applicable rules and regulations of that jurisdiction.

In the case of any shares of common stock being offered to a financial intermediary as that term is used in Article 3(2) of the Prospectus Directive, each such financial intermediary will be deemed to have represented, acknowledged and agreed that the shares of common stock acquired by it in the offer have not been acquired on a non-discretionary basis on behalf of, nor have they been acquired with a view to their offer or resale to, persons in circumstances which may give rise to an offer of any shares of common stock to the public other than their offer or resale in a Relevant Member State to qualified investors as so defined or in circumstances in which the prior consent of the representative has been obtained to each such proposed offer or resale.

For the purposes of this provision, the expression an “offer of shares to the public” in relation to any shares of common stock in any Relevant Member State means the communication in any form and by means of sufficient information on the terms of the offer and the shares of common stock to be offered so as to enable an investor to decide to purchase shares of common stock, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, the expression “Prospectus Directive” means Directive 2003/71/EC (as amended, including by Directive 2010/73/EU), and includes any relevant implementing measure in the Relevant Member State.

Any person in the United Kingdom that is not a relevant person should not act or rely on the information included in this document or use it as basis for taking any action. In the United Kingdom, any investment or investment activity that this document relates to may be made or taken exclusively by relevant persons.

The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

Pursuant to section 3A.3 of National Instrument 33-105 Underwriting Conflicts (NI 33-105), the underwriters are not required to comply with the disclosure requirements of NI 33-105 regarding underwriter conflicts of interest in connection with this offering.

STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, any prospectus supplement, any related free writing prospectus, and the documents incorporated by reference herein and therein may contain forward-looking statements regarding future events or our future financial and operational performance, within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Exchange Act. Forward-looking statements include statements regarding markets for our products; trends in net sales, gross profits and estimated expense levels; liquidity and anticipated cash needs and availability; and any statement that contains the words “anticipate,” “believe,” “plan,” “forecast,” “foresee,” “estimate,” “project,” “expect,” “seek,” “target,” “intend,” “goal” and other similar expressions.

The forward-looking statements included in this prospectus, any prospectus supplement, any related free writing prospectus and the documents incorporated by reference herein and therein reflect our current expectations and beliefs, and we do not undertake publicly to update or revise these statements, even if experience or future changes make it clear that any projected results expressed in this prospectus, any prospectus supplement, any related free writing prospectus and the documents incorporated by reference herein and therein will not be realized. In addition, the inclusion of any statement in this prospectus, any prospectus supplement, any related free writing prospectus and the documents incorporated by reference herein and therein does not constitute an admission by us that the events or circumstances described in such statement are material. Furthermore, we wish to caution and advise readers that these statements are based on assumptions that may not materialize and may involve risks and uncertainties, many of which are beyond our control that could cause actual events or performance to differ materially from those contained or implied in these forward-looking statements.

Among the factors that could cause actual results to differ materially are the factors discussed under “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 28, 2015 and each subsequently filed Quarterly Report on Form 10-Q. We also will include or incorporate by reference in each prospectus supplement important factors that we believe could cause actual results or events to differ materially from the forward-looking statements that we make. Should one or more known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could differ materially from past results and those anticipated, estimated, projected, or implied by these forward-looking statements. You should consider these factors and the other cautionary statements made in this prospectus, any prospectus supplement, any related free writing prospectus or the documents we incorporate by reference herein or therein as being applicable to all related forward-looking statements wherever they appear in this prospectus, any prospectus supplement, any related free writing prospectus or the documents incorporated by reference. While we may elect to update forward-looking statements wherever they appear in this prospectus, any prospectus supplement, any related free writing prospectus or the documents incorporated by reference, we do not assume, and specifically disclaim, any obligation to do so, whether as a result of new information, future events, or otherwise, except as required by law. Because of these uncertainties, you should not place undue reliance on these forward-looking statements.

DESCRIPTION OF COMMON STOCK

This section describes the general terms of our common stock. A prospectus supplement may provide information that is different from this prospectus. If the information in the prospectus supplement with respect to our common stock being offered differs from this prospectus, you should rely on the information in the prospectus supplement. A copy of our certificate of incorporation, as amended, has been incorporated by reference from our filings with the SEC as an exhibit to the registration statement of which this prospectus forms a part. Our common stock and the rights of the holders of our common stock are subject to the applicable provisions of the Delaware General Corporation Law, to which we refer as Delaware law, our certificate of incorporation, as amended, our fourth amended and restated bylaws, as amended, and the rights of the holders of our preferred stock, if any, as well as some of the terms of our credit agreement and any other outstanding indebtedness.

As of November 2, 2016, under our certificate of incorporation, as amended, we had the authority to issue 300,000,000 shares of common stock, par value $0.001 per share. As of November 2, 2016, 100,393,160 shares of our common stock were outstanding and were held of record by approximately 297 stockholders.

The following description of our common stock, and any description of our common stock in a prospectus supplement may not be complete and is subject to, and qualified in its entirety by reference to, Delaware law and the actual terms and provisions contained in our certificate of incorporation, as amended, and fourth amended and restated bylaws, as amended, each as amended from time to time.

Voting Rights

Each outstanding share of our common stock is entitled to one vote per share of record on all matters submitted to a vote of stockholders and to vote together as a single class for the election of directors and in respect of other corporate matters. At a meeting of stockholders at which a quorum is present, for all matters other than the election of directors, all questions shall be decided by the vote of the holders of a majority of the outstanding shares of stock entitled to vote thereon present in person or by proxy at the meeting, unless the matter is one upon which a different vote is required by express provision of law or our certificate of incorporation, as amended, or fourth amended and restated bylaws, as amended. Directors will be elected by a plurality of the votes of the shares present at a meeting. Holders of shares of common stock do not have cumulative voting rights with respect to the election of directors or any other matter.

Dividends

Holders of our common stock are entitled to receive dividends or other distributions when, as, and if declared by our board of directors. The right of our board of directors to declare dividends, however, is subject to any rights of the holders of other classes of our capital stock, any indebtedness outstanding from time to time, and the availability of sufficient funds under Delaware law to pay dividends.

Preemptive Rights

The holders of our common stock do not have preemptive rights to purchase or subscribe for any of our capital stock or other securities.

Redemption

The shares of our common stock are not subject to redemption by operation of a sinking fund or otherwise.

Liquidation Rights

In the event of any liquidation, dissolution, or winding up of our company, after the payment or provisions for payment of all debts and liabilities of the corporation and all preferential amounts to which the holders of our

Table of Contents

preferred stock are entitled with respect to the distribution of assets in liquidation, the holders of shares of our common stock are entitled to receive any of our assets available for distribution to our stockholders ratably in proportion to the number of shares held by them.

DESCRIPTION OF PREFERRED STOCK

This section describes the general terms of our preferred stock to which any prospectus supplement may relate. A prospectus supplement will describe the terms relating to any preferred stock to be offered by us in greater detail and may provide information that is different from terms described in this prospectus. If the information in the prospectus supplement with respect to the particular preferred stock being offered differs from this prospectus, you should rely on the information in the prospectus supplement. A copy of our certificate of incorporation, as amended, has been incorporated by reference from our filings with the SEC as an exhibit to the registration statement. A certificate of designation or amendment to our certificate of incorporation, as amended, will specify the terms of the preferred stock being offered, and will be filed or incorporated by reference as an exhibit to the registration statement before the preferred stock is issued. The following description of our preferred stock, and any description of the preferred stock in a prospectus supplement, may not be complete and is subject to, and qualified in its entirety by reference to, Delaware law and the actual terms and provisions contained in our certificate of incorporation, as amended, and fourth amended and restated bylaws, as amended, each as amended from time to time.

As of November 2, 2016, under our certificate of incorporation, as amended, we had the authority to issue 15,000,000 shares of preferred stock, par value $0.001 per share, which are issuable in series on terms to be determined by our board of directors. Accordingly, our board of directors is authorized, without action by the stockholders, to issue preferred stock from time to time with such dividend, liquidation, conversion, voting, and other rights and restrictions as it may determine. All shares of any one series of our preferred stock will be identical, except that shares of any one series issued at different times may differ as to the dates from which dividends may be cumulative. All series shall rank equally and shall provide for other terms as described in the applicable prospectus supplement. As of November 2, 2016, there were no outstanding shares of our preferred stock.

Unless provided in a prospectus supplement, the shares of our preferred stock to be issued will have no preemptive rights. Any prospectus supplement offering our preferred stock will furnish the following information with respect to the preferred stock offered by that prospectus supplement:

Table of Contents

If our board of directors decides to issue any preferred stock, it may discourage or make more difficult a merger, tender offer, business combination, or proxy contest, assumption of control by a holder of a large block of our securities, or the removal of incumbent management, even if these events were favorable to the interests of stockholders. Our board of directors, without stockholder approval, may issue preferred stock with voting and conversion rights and dividend and liquidation preferences that may adversely affect the holders of our other equity or debt securities.

DESCRIPTION OF DEBT SECURITIES

The debt securities will constitute either senior or subordinated debt of TTM Technologies, Inc. The debt securities that are sold may be exchangeable for and/or convertible into common stock or any of the other securities that may be sold under this prospectus. The debt securities will be issued under one or more separate indentures between us and a designated trustee. We will include in a prospectus supplement the specific terms of each series of senior or subordinated debt securities being offered, including the terms, if any, on which a series of senior or subordinated debt securities may be convertible into or exchangeable for other securities. In addition the material terms of any indenture, which will govern the rights of the holders of our senior or subordinated debt securities will be set forth in the applicable prospectus supplement.

DESCRIPTION OF WARRANTS

We may issue, either separately or together with other securities, warrants for the purchase of any of the other types of securities that we may sell under this prospectus.

The warrants will be issued under warrant agreements to be entered into between us and a bank or trust company, as warrant agent, all to be set forth in the applicable prospectus supplement relating to any or all warrants in respect of which this prospectus is being delivered. Copies of the form of agreement for each warrant, which we refer to collectively as “warrant agreements,” including the forms of certificates representing the warrants, which we refer to collectively as “warrant certificates,” and reflecting the provisions to be included in such agreements that will be entered into with respect to the particular offerings of each type of warrant, will be filed with the SEC and incorporated by reference as exhibits to the registration statement of which this prospectus forms a part.

The following description sets forth certain general terms and provisions of the warrants to which any prospectus supplement may relate. The particular terms of the warrants to which any prospectus supplement may relate and the extent, if any, to which the general provisions may apply to the warrants so offered will be described in the applicable prospectus supplement. To the extent that any particular terms of the warrants, warrant agreements or warrant certificates described in a prospectus supplement differ from any of the terms described below, then the terms described below will be deemed to have been superseded by that prospectus supplement. We encourage you to read the applicable warrant agreement and certificate for additional information before you purchase any of our warrants.

General

The prospectus supplement will describe the terms of the warrants in respect of which this prospectus is being delivered, as well as the related warrant agreement and warrant certificates, including the following, where applicable:

Table of Contents

The description in the prospectus supplement will not necessarily be complete and will be qualified in its entirety by reference to the warrant agreement and warrant certificate relating to the warrants being offered.

Exercise of Warrants

Each warrant will entitle the holder to purchase for cash that principal amount of, or number of, securities, as the case may be, at the exercise price set forth in, or to be determined as set forth in, the applicable prospectus supplement relating to the warrants. Upon receipt of payment and the warrant certificate properly completed and duly executed, we will, as soon as practicable, issue the securities purchasable upon exercise of the warrant.

No Rights of Security Holder Prior to Exercise

Before the exercise of their warrants, holders of warrants will not have any of the rights of holders of the securities purchasable upon the exercise of the warrants, and will not be entitled to:

DESCRIPTION OF UNITS

We may, from time to time, issue units composed of one or more of the other securities that may be offered under this prospectus, in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately at any time, or at any time before a specified date.

Any applicable prospectus supplement may describe, among other things:

17

Table of Contents

FORMS OF SECURITIES

Each debt security, warrant and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Certificated securities will be issued in definitive form and global securities will be issued in registered form. Definitive securities name you or your nominee as the owner of the security, and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Global securities name a depositary or its nominee as the owner of the debt securities, warrants or units represented by these global securities. The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Registered Global Securities

We may issue the registered debt securities, warrants and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement. We understand that under existing industry practices, if we request any

18

Table of Contents

action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement, guaranteed trust preferred security or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, premium, if any, and interest payments on debt securities, and any payments to holders with respect to warrants, guaranteed trust preferred securities or units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of TTM Technologies, Inc., the trustees, the warrant agents, the unit agents or any other agent of TTM Technologies, Inc., agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

SELLING SECURITYHOLDERS

Selling securityholders to be named in a prospectus supplement may, from time to time, offer and sell some or all of our securities held by them pursuant to this prospectus and the applicable prospectus supplement. Such selling securityholders may sell our securities held by them to or through underwriters, dealers or agents or directly to purchasers or as otherwise set forth in the applicable prospectus supplement. See “Plan of Distribution.” Such selling securityholders may also sell, transfer or otherwise dispose of some or all of our securities held by them in transactions exempt from the registration requirements of the Securities Act.

We will provide you with a prospectus supplement, which will, among other things, set forth the name of each selling securityholder and the number of our securities beneficially owned by such selling securityholders that are covered by such prospectus supplement.

PLAN OF DISTRIBUTION

We and/or any selling securityholder may sell the securities described in this prospectus from time to time in one or more of the following ways:

The prospectus supplement with respect to the offered securities will describe the terms of the offering, including the following:

Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time. In addition, to the extent this prospectus is used by any selling securityholder to resell common stock or other securities, information with respect to the selling securityholder will be contained in a prospectus supplement to this prospectus, in a post-effective amendment or in filings we make with the SEC under the Exchange Act that are incorporated by reference.

We and/or any selling securityholder may distribute the securities from time to time in one or more of the following ways:

Unless otherwise indicated in the applicable prospectus supplement, if we or any selling securityholder use underwriters for a sale of securities, the underwriters will acquire the securities for their own account and may be resold as described above. The obligations of the underwriters to purchase the securities will be subject to the conditions set forth in the applicable underwriting agreement. Unless otherwise indicated in a prospectus supplement, the underwriters will be obligated to purchase all the securities of the series offered if they purchase

21

Table of Contents

any of the securities of that series. Underwriters and agents may be customers of, engage in transactions with, or perform services for TTM Technologies, Inc. and its affiliates in the ordinary course of business. We or any selling securityholder will describe in the prospectus supplement naming the underwriter the nature of any such relationship. We or any selling securityholder may designate agents who agree to use their reasonable efforts to solicit purchases for the period of their appointment or to sell securities on a continuing basis. We or any selling securityholder may also sell securities directly to one or more purchasers without using underwriters or agents.

Underwriters, dealers, or agents may receive compensation in the form of discounts, concessions, or commissions from us or any selling securityholder or from purchasers of the securities as their agents in connection with the sale of the securities. These underwriters, dealers, or agents may be considered to be underwriters under the Securities Act. As a result, discounts, commissions, or profits on resale received by underwriters, dealers, or agents may be treated as underwriting discounts and commissions. Each prospectus supplement will identify any underwriter, dealer, or agent and describe any compensation received by them from us or any selling securityholder.

Unless otherwise specified in the applicable prospectus supplement, each class or series of securities will be a new issue with no established trading market, other than our common stock, which is listed on the NASDAQ Global Select Market. We may elect to list any other class or series of securities on any exchange, but we are not obligated to do so. It is possible that one or more underwriters may make a market in a class or series of securities, but the underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to the liquidity of the trading market for any of the securities.

Underwriters, dealers, and agents may be entitled under agreements entered into with us or any selling securityholder to indemnification against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments they may be required to make in respect of these liabilities thereof. Underwriters, dealers, and agents and their affiliates may be customers of, may engage in transactions with, or perform services for us in the ordinary course of business for which they receive compensation.
