We obtained the market and competitive position data contained or incorporated by reference in this prospectus supplement and the accompanying prospectus from our own research, surveys or studies conducted by third parties and industry or general publications. Industry publications and surveys generally state that they have obtained information from sources believed to be reliable, but do not guarantee the accuracy and completeness of such information. While we believe that each of these studies and publications is reliable, neither we nor the underwriters have independently verified such data and neither we nor the underwriters make any representation as to the accuracy of such information. Similarly, we believe our internal research is reliable, but it has not been verified by any independent sources and the underwriters do not make any representation as to its accuracy.

Except for historical information, certain matters contained or incorporated by reference in this prospectus supplement and the accompanying prospectus are, or may be deemed to be, forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. The words "will," "may," "designed to," "believe," "should," "anticipate," "plan," "expect," "intend," "estimate" and similar expressions identify forward-looking statements, which speak only as of the date they were made. Because these forward-looking statements are subject to risks and uncertainties, actual results could differ materially from the expectations expressed in the forward-looking statements. Important factors that could cause actual results to differ materially from the expectations reflected in the forward-looking statements include the risks identified under the section captioned "Risk Factors" in this prospectus supplement and those described in Item 1A, "Risk Factors" and Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2019 10-K, as updated by quarterly and other reports and documents we file with the SEC after the date of this prospectus supplement and that are incorporated by reference in this prospectus supplement. In addition, new risks emerge from time to time and it is not possible for management to predict all such risk factors or to assess the impact of such risk factors on our business. Given these risks and uncertainties, the reader should not place undue reliance on these forward-looking statements. We claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 for our forward-looking statements. We disclaim any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise, except as required by law.

Recent Developments

On May 30, 2019, we commenced a cash tender offer (the "Tender Offer") pursuant to which we are offering to purchase any and all of our $500 million aggregate outstanding principal amount of 4.625% notes due 2020 (the "2020 Notes"), on the terms and subject to the conditions described in the offer to purchase and the related letter of transmittal and notice of guaranteed delivery. The Tender Offer will expire at 5:00 p.m., New York City time, on June 5, 2019, unless extended or terminated earlier by us, and is subject to certain conditions, including the condition that we have successfully completed the offering of the notes offered hereby, on terms satisfactory to us in our sole discretion, and have received net proceeds from the offering in an amount sufficient to fund (i) the purchase of all

2020 Notes accepted in the Tender Offer and (ii) the redemption, at the make-whole redemption price calculated in accordance with the terms of the indenture governing the 2020 Notes, of any 2020 Notes remaining outstanding after the Tender Offer (the "2020 Notes Redemption"), including the payment of all premiums, accrued interest and costs and expenses in connection with the Tender Offer and the 2020 Notes Redemption. This offering is not conditioned on the completion of the Tender Offer.

We are permitted, among other things, to amend, extend, terminate or withdraw the Tender Offer, and there can be no assurance that we will consummate the Tender Offer. There can be no assurance as to the principal amount of 2020 Notes that will be tendered or accepted for purchase pursuant to the Tender Offer.

To the extent any of the outstanding 2020 Notes are not tendered and accepted in the Tender Offer, we currently expect that we will exercise our right to complete the 2020 Notes Redemption.

We intend to use a substantial portion of the net proceeds from this offering to complete the Tender Offer and the 2020 Notes Redemption, including the payment of all premiums, accrued interest and costs and expenses related to the foregoing, and to use the remaining net proceeds for general corporate purposes, which may include the prepayment of other outstanding debt. See "Use of Proceeds" and "Capitalization."

This prospectus supplement is not an offer to purchase or a solicitation of an offer to sell the 2020 Notes and does not constitute a redemption notice for the 2020 Notes. The Tender Offer is being made only by and pursuant to the terms of a separate offer to purchase.

(1): During fiscal year 2019, we took targeted actions to optimize our portfolio, most notably within our Consumer Technologies Group business segment. We completed the wind down of our NIKE operations in Mexico in the third quarter of fiscal year 2019 and recognized charges of $66 million for the fiscal year ended March 31, 2019, primarily for non-cash asset impairments. In total, we recognized restructuring charges of approximately $113 million during the fiscal year ended March 31, 2019. In addition to the charges related to the NIKE operations in Mexico, we executed targeted head-count reductions at existing operating and design sites and corporate functions and exited certain immaterial businesses. Of these total charges, approximately $99 million was recognized as a component of cost of sales during the fiscal year ended March 31, 2019.

During fiscal year 2018, we initiated targeted restructuring activities, focused on optimizing our cost structure in lower growth areas and, more importantly, streamlining certain corporate and segment functions. The objective of the plan is to make our company a faster, more responsive and agile company, better positioned to react to marketplace opportunities. We recognized $79 million of pre-tax cash charges, predominantly related to employee severance costs and $12 million of pre-tax non-cash charges for asset impairment and other exit charges. We classified $67 million of these charges as a component of cost of sales and $24 million as a component of selling, general and administrative expenses during fiscal year 2018.

During fiscal year 2017, we initiated a restructuring plan to accelerate our ability to support more Sketch-to-Scale® efforts across our company and reposition away from historical legacy programs and structures through rationalizing our current footprint at existing sites, including certain corporate selling, general and administrative functions. We recognized $49 million of pre-tax restructuring charges predominantly for employee termination costs. We classified $39 million of these charges as a component of cost of sales and $10 million as a component of selling, general and administrative expenses during fiscal year 2017.

(2)

During the last half of fiscal year 2019, we reassessed our strategy with respect to our entire investment portfolio. As a result, we recognized an aggregate net charge related to investment impairments and dispositions of approximately $193 million for the year ended March 31, 2019. The aggregate charge was primarily driven by write-downs of our investment positions in a non-core cost method investment and Elementum SCM (Cayman) Ltd ("Elementum") that were recognized in the third and fourth quarter of fiscal 2019, respectively. We also incurred other investment impairments that were individually immaterial as a result of our strategy shift and due to market valuation changes. Offsetting these charges was an $87 million non-cash gain from the deconsolidation of Bright Machines (formally known as AutoLab AI). Refer to note 2 to the consolidated financial statements in Item 8, "Financial Statements and Supplementary Data" in our 2019 10-K for details on the investment impairments and the deconsolidation of Bright Machines.

Fiscal year 2018 includes a $152 million gain from the deconsolidation of our subsidiary, Elementum and a $39 million gain from the sale of Wink Labs Inc. See note 6 and note 2 to the consolidated financial statements in Item 8, "Financial Statements and Supplementary Data" in our Annual Report for the fiscal year ended March 31, 2018 for details of the deconsolidation of Elementum and the disposition of Wink Labs Inc., respectively. We also recorded $22 million related to the impairment of certain non-core investments during fiscal year 2018. No other components of other charges and income, net incurred during fiscal year 2018 were material.

Fiscal year 2017 includes a $7 million loss attributable to a non-strategic facility sold during the second quarter of fiscal year 2017. No other components of other charges and income, net incurred during fiscal year 2017 were material.

Working capital is defined as current assets, less current liabilities.

Investing in the notes involves risk. In deciding whether to invest in the notes, you should carefully consider the risks described below and the risks described in Part I, "Item 1A. Risk Factors" in our 2019 10-K, which risks are incorporated by reference in this prospectus supplement and the accompanying prospectus, in addition to the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. Our business, results of operations and financial condition may be materially adversely affected and the value of the notes could decline due to any of the risks described below or described in Part I, "Item 1A. Risk Factors" in our 2019 10-K. In addition, we may face risks that are not described below or in Part I, "Item 1A. Risk Factors" in our 2019 10-K, or incorporated by reference in this prospectus supplement and the accompanying prospectus because we are either not presently aware of them or we currently believe that they are not material. Such risks may be harmful to our business and the value or liquidity of the notes and result in the loss of all or part of your investment in the notes.

The notes will be structurally subordinated to the indebtedness and other liabilities of our subsidiaries, including any guarantees or preferred stock of our subsidiaries.

The notes will not be guaranteed by any of our subsidiaries and will therefore be structurally subordinated to any indebtedness and other liabilities of our subsidiaries. As of March 31, 2019, the total liabilities of our subsidiaries, excluding intercompany debt but including trade payables, were approximately $7.7 billion. Our subsidiaries are separate and distinct legal entities, and have no obligation to pay any amounts due on the notes or to provide us with funds for our payment obligations. Our right to receive any assets of any of our subsidiaries, as an equity holder of that subsidiary, upon its liquidation or reorganization, and the consequent right of the holders of the notes to participate in those assets, will be structurally subordinated to the claims of that subsidiary's creditors, including trade creditors, except to the extent that we are recognized as a creditor of that subsidiary, in which case our claims would still be effectively subordinated to any mortgage or other liens on the assets of that subsidiary and would be subordinated to any preferred stock or indebtedness of that subsidiary senior to that held by us.

In addition, our term loan due November 2021, our term loan due June 2022, our term loan due April 2024, our revolving credit facility, our 2020 Notes, our 5.000% Notes due February 2023 and our 4.750% Notes due June 2025, which are not currently guaranteed by our subsidiaries, contain contingent future guarantee provisions whereby certain of our subsidiaries may become guarantors of our obligations thereunder. The notes will not have the benefit of any such contingent future guarantee provisions. As a result, if any such guarantee is executed by one or more of our subsidiaries, holders of the notes would not receive the benefit of that guarantee and would therefore be structurally subordinated to any indebtedness that receives the benefit of that guarantee to the extent of the assets of the subsidiaries providing that guarantee.

The notes will be unsecured and will be effectively subordinated to all of our secured obligations to the extent of the value of the collateral securing such obligations.

As of March 31, 2019, we had no secured indebtedness, other than capital leases. Although we currently do not have any material amount of secured indebtedness outstanding, we may incur additional secured indebtedness in the future. Holders of any of our future secured indebtedness will have claims that are prior to your claims as holders of the notes to the extent of the value of the assets securing such indebtedness, subject to certain rights accorded under the indenture for the notes to become secured pari passu with other secured indebtedness. In the event of any distribution or payment of our assets in any foreclosure, dissolution, winding-up, liquidation, reorganization or other bankruptcy

proceeding, holders of our secured indebtedness will have prior claim to our assets that constitute their collateral. Holders of the notes will participate ratably with all holders of our other unsecured indebtedness that is deemed to be of the same class as the notes. In that event, because the notes will not be secured by any of our assets (except under the limited rights to be secured pari passu referred to above), it is possible that our remaining assets may not be sufficient to satisfy your claims in full after our secured claims are repaid.

We conduct substantially all of our operations through our subsidiaries and depend on cash flow from our subsidiaries to meet our obligations. Your right to receive payments on the notes could be adversely affected if any of our subsidiaries becomes unable to distribute cash to us.

Because substantially all of our operations are conducted through our subsidiaries, our cash flow and ability to service debt, including the notes, will depend in part upon the earnings of our subsidiaries and the distribution of those earnings to, or under loans or other payments of funds by our subsidiaries to, us. Provisions of law, such as those requiring that dividends be paid only from surplus, could limit the ability of our subsidiaries to make payments or other distributions to us. Furthermore, these subsidiaries could in certain circumstances agree to contractual restrictions on their ability to make distributions.

As of March 31, 2019, over half of our cash and cash equivalents were held by foreign subsidiaries outside of Singapore. Local government regulations may restrict our ability to move cash balances to meet cash needs under certain circumstances. Although substantially all of the amounts held outside of Singapore could be repatriated, under current laws, a significant amount could be subject to income tax withholdings. Repatriation could result in an additional income tax payment; however, our intent is to permanently reinvest our foreign earnings considered indefinitely reinvested outside of Singapore (approximately $1.6 billion as of March 31, 2019) and our current plans do not demonstrate a need to repatriate them to fund our operations in jurisdictions outside of where they are held. Where local restrictions prevent an efficient intercompany transfer of funds, our intent is that cash balances would remain outside of Singapore and we would meet our liquidity needs through ongoing cash flows, external borrowings, or both.

Servicing our debt will require a significant amount of cash. Our ability to generate sufficient cash depends on numerous factors beyond our control, and we may be unable to generate sufficient cash flow to service our debt obligations, including making payments on the notes.

As of March 31, 2019, after giving pro forma effect to this offering and the application of the net proceeds from this offering, we would have had $ billion of total indebtedness, including the notes, substantially all of which was unsecured. Our ability to make payments on and to refinance our existing and future indebtedness, including the notes, will depend on our current and future ability to generate cash from our operations. Our ability to generate cash from our operations is subject to economic and financial conditions in our industry, the global economy and legislative, regulatory and other factors that are beyond our control. We cannot assure you that our business will generate sufficient cash flow from operations, or that future borrowings will be available to us under our revolving credit facility or otherwise, in an amount sufficient to fund our liquidity needs, including the payment of principal and interest on the notes.

A substantial decrease in our operating cash flow or a substantial increase in our expenses could make it difficult for us to meet debt service requirements and could require us to modify our operations, including by selling assets, reducing our capital expenditures, refinancing all or a portion of our existing debt or obtaining additional financing. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations. Our ability to restructure or refinance our debt will depend on the condition of the capital markets and our financial condition at

such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations.

The provisions contained in the agreements relating to our indebtedness, including our term loan due November 2021, our term loan due June 2022, our term loan due April 2024, our revolving credit facility, the indenture governing our 2020 Notes and our 5.000% Notes due February 2023 and the indenture governing our 4.750% Notes due June 2025, do not completely prohibit us from incurring additional indebtedness, and the amount of indebtedness that we could incur could be substantial. Our loan agreements contain customary restrictions, subject to a number of exceptions and limitations, on our and our subsidiaries' ability to incur certain debt, enter into sale-leaseback transactions, and incur liens. The loan agreements also require that we maintain a maximum ratio of total indebtedness to EBITDA (earnings before interest expense, taxes, depreciation and amortization), and a minimum interest coverage ratio, which may be suspended in certain circumstances. The indentures governing our existing notes contain covenants, which are subject to a number of significant limitations and exceptions, that restrict our and our subsidiaries' ability to create liens, enter into sale-leaseback transactions, or create, incur, issue, assume or guarantee any funded debt. The indenture governing the notes offered hereby will not prohibit us or our subsidiaries from incurring indebtedness, and permits us to incur secured indebtedness subject to the restrictions set forth therein. Accordingly, we or our subsidiaries could incur significant additional indebtedness in the future, especially if our other indebtedness matures or is repaid prior to its maturity. If we incur additional unsecured senior indebtedness, the holders of that debt will be entitled to share ratably with the holders of the notes in any proceeds distributed in connection with any bankruptcy, liquidation, reorganization or similar proceedings. This may have the effect of reducing the amount of proceeds paid to holders of the notes. If we incur additional indebtedness, the related risks that we now face could intensify. As of March 31, 2019, we had no borrowings outstanding under our revolving credit facility and had borrowing availability of $1.75 billion under that facility.

If we default on our obligations to pay our other indebtedness, we may not be able to make payments on the notes.

Any default under the agreements governing our other indebtedness could result in us being unable to make payments of principal, premium, if any, or interest on the notes and could substantially decrease the market value of the notes. If we are unable to generate sufficient cash flow and are otherwise unable to obtain funds necessary to meet required payments of principal, premium, if any, or interest on our other indebtedness, or if we otherwise fail to comply with the various covenants in the instruments governing our other indebtedness, we could be in default under the terms of the agreements governing such indebtedness. In the event of such default, the holders of such indebtedness could elect to declare all the funds borrowed thereunder to be due and payable, together with accrued and unpaid interest. Any such default or acceleration could also give the holders of any of our other indebtedness the right to accelerate such indebtedness, which would exacerbate the risks described above.

The negative covenants in the indenture that governs the notes may have a limited effect.

The indenture governing the notes offered hereby will contain limited covenants, including those restricting our ability and certain of our subsidiaries' ability to create certain liens and enter into certain sale and leaseback transactions. The limitation on liens and limitation on sale and leaseback transactions covenants contain exceptions that will allow us and our subsidiaries to incur liens with respect to material assets and additional subsidiary debt and enter into sale and leaseback transactions.

See "Description of Notes—Certain Covenants." In light of these exceptions, holders of the notes may be structurally or contractually subordinated to new lenders.

The notes will constitute a new issue of securities with no established trading market, and we do not intend to apply for listing of the notes on any securities exchange or automated quotation system. Accordingly, there can be no assurance as to the development or liquidity of any market for the notes. The underwriters have advised us that they currently intend to make a market in the notes, but they are not obligated to do so, and any market making with respect to the notes may be discontinued at any time without notice. Accordingly, there can be no assurance regarding any future development of a trading market for the notes or the ability of holders of the notes to sell their notes at all or the price at which such holders may be able to sell their notes. If a trading market were to develop, the notes may trade at prices that are higher or lower than their initial offering price, depending on many factors, including prevailing interest rates, our operating results and financial condition, the time to maturity and the outstanding principal amount of the notes, the then-current ratings assigned to the notes and the market for similar securities.

We may not be able to repurchase the notes upon a change of control repurchase event.

As described under "Description of Notes—Repurchase of Notes Upon a Change of Control Repurchase Event" in this prospectus supplement, upon the occurrence of a change of control repurchase event we will be required to offer to repurchase all outstanding notes at a price equal to 101% of the principal amount of the notes, together with accrued and unpaid interest to the date of repurchase. In addition, upon the occurrence of a change of control repurchase event, we also would be required to offer to repurchase our outstanding 2020 Notes, our outstanding 5.000% Notes due February 2023 and our outstanding 4.750% Notes due June 2025. We may not have sufficient funds at the time of the change of control repurchase event to make the required repurchase of these notes or have the ability to arrange necessary financing on acceptable terms, or at all.

A change of control giving rise to a change of control repurchase event will also be an event of default under the agreements relating to our term loan due November 2021, our term loan due June 2022, our term loan due April 2024, and our revolving credit facility and may be an event of default under our future debt instruments. This event will permit the lenders under these debt agreements to accelerate the indebtedness outstanding thereunder. If we are required to repurchase the notes pursuant to a change of control repurchase event and repay certain amounts outstanding under these debt agreements if such indebtedness is accelerated, we are likely to require third-party financing. We cannot be sure that we would be able to obtain third-party financing on acceptable terms, or at all.

A downgrade, suspension or withdrawal of the rating assigned by a rating agency to our debt securities could cause the liquidity or market value of the notes to decline significantly and increase our cost of borrowing.

Our credit ratings are an assessment by rating agencies of our ability to pay our debts when due. In general, rating agencies base their ratings on many quantitative and qualitative factors, including, but not limited to, capital adequacy, liquidity, asset quality, business mix and quality of earnings, and, as a result, we may not be able to maintain our current credit ratings.

Credit rating agencies continually review their ratings for the companies that they follow, including us. Borrowing under our credit facilities, as well as the future incurrence of additional secured or additional unsecured indebtedness, may cause the rating agencies to reassess the ratings assigned to our debt securities. Any such action may lead to a downgrade of any rating assigned to the notes or in the assignment of a rating for the notes that is lower than might otherwise be the case. Real or anticipated

changes in our credit ratings could cause the liquidity or market value of the notes to decline significantly and could increase our corporate borrowing costs.

There can be no assurance that the ratings assigned to the notes will remain for any given period of time or that these ratings will not be lowered or withdrawn entirely by a rating agency if, in that rating agency's judgment, future circumstances relating to the basis of the rating, such as adverse changes in our company, so warrant. Credit ratings are not a recommendation to buy, sell or hold any security, and may be revised or withdrawn at any time by the issuing organization in its sole discretion. Neither we nor any underwriter undertakes any obligation to maintain the ratings or to advise holders of the notes of any changes in ratings. Each agency's rating should be evaluated independently of any other agency's rating.

We have the right to redeem some or all of the notes prior to maturity. We may redeem the notes at times when prevailing interest rates may be relatively low. Accordingly, you may not be able to reinvest the redemption in a comparable security at an effective interest rate as high as that of the notes.

An increase in market interest rates could result in a decrease in the market value of the notes.

In general, as market interest rates rise, debt securities bearing interest at fixed rates of interest such as the notes generally decline in market value. Consequently, if you purchase notes in this offering and market interest rates increase, the market values of those notes may decline. We cannot predict the future level of market interest rates.

We expect to receive net proceeds from this offering of approximately $ after deducting the underwriting discount and estimated offering expenses payable by us. We intend to use a substantial portion of the net proceeds from this offering to complete the Tender Offer and the 2020 Notes Redemption, including the payment of all premiums, accrued interest and costs and expenses related to the foregoing, and to use the remaining net proceeds for general corporate purposes, which may include the prepayment of other outstanding debt. See "Summary—Recent Developments." As of March 31, 2019, there was outstanding $500 million aggregate principal amount of 2020 Notes. The interest rate on our 2020 Notes is 4.625% per annum and these notes mature on February 15, 2020.

Certain underwriters or their affiliates hold a portion of our 2020 Notes. To the extent that any of the underwriters or their respective affiliates tender the 2020 Notes held by them and have them accepted for purchase in the Tender Offer or hold 2020 Notes that are redeemed in the 2020 Notes Redemption, they may receive a portion of the net proceeds of this offering. In addition, the representatives of the several underwriters of this offering and/or their respective affiliates are acting as the dealer managers in the Tender Offer and may receive fees in connection therewith. See "Underwriting."

The following table sets forth our cash and cash equivalents, short-term debt and current portion of long-term debt and consolidated capitalization as of March 31, 2019:

You should read this table in conjunction with the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section and the accompanying financial statements and related notes contained in the 2019 10-K, which is incorporated by reference into this prospectus supplement.

The % notes due 20 (the "notes") will constitute a series of debt securities that will be issued under an indenture, to be dated as of , 2019 (the "base indenture"), as supplemented by a supplemental indenture to be dated as of the date of initial issuance of the notes (the base indenture, as so supplemented, the "indenture") between Flex and U.S. Bank National Association, as trustee (the "trustee"). The following summary of provisions of the indenture and the notes does not purport to be complete and is subject to, and qualified in its entirety by reference to, all of the provisions of the indenture, including definitions therein of certain terms and provisions made a part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act"). This summary may not contain all information that you may find useful. You should read the indenture and the notes, copies of which are available from Flex upon request. References to "Flex," "we," "us" and "our" in this section of this prospectus supplement are only to Flex Ltd. and not to any of its subsidiaries.

Interest on each note will be paid to the person in whose name that note is registered at the close of business on or , as the case may be, immediately preceding the relevant interest payment date. Interest on the notes will be computed on the basis of a 360-day year comprised of twelve 30-day months.

If any interest or other payment date of a note falls on a day that is not a business day, the required payment of principal, premium, if any, or interest will be due on the next succeeding business day as if made on the date that the payment was due, and, unless Flex defaults on such payment, no interest will accrue on that payment for the period from and after that interest or other payment date, as the case may be, to the date of that payment on the next succeeding business day. The term "business day" means, with respect to the notes, any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law, regulation or executive order to close in The City of New York or in a place of payment.

The notes will be subject to defeasance as described under "—Discharge, Defeasance and Covenant Defeasance" below.

Flex may, subject to compliance with applicable law, at any time purchase notes in the open market or otherwise.

The notes will rank equally with all of our existing and future senior and unsecured indebtedness (as defined below). As of March 31, 2019, after giving pro forma effect to this offering and the application of the net proceeds from this offering, Flex would have had $ billion of total indebtedness, including the notes, substantially all of which was unsecured.

A substantial portion of our operations are conducted through our subsidiaries. Our existing and future subsidiaries will not be required to guarantee the notes. Claims of creditors of our subsidiaries, including trade creditors, and creditors holding debt and guarantees issued by our subsidiaries, and claims of preferred stockholders (if any) of our subsidiaries generally will have priority with respect to the assets and earnings of our subsidiaries over the claims of creditors of Flex, including holders of the notes. As of March 31, 2019, the total liabilities of our subsidiaries, excluding intercompany debt but including trade payables, were approximately $7.7 billion.

The indenture does not limit the amount of indebtedness that we or our subsidiaries may incur.

The indenture will provide that any amounts paid, or caused to be paid, by us or our assignee, or any of our successors, under the indenture will be paid without deduction or withholding for any and all present and future taxes, levies, imposts or other governmental charges ("taxes") whatsoever imposed, assessed, levied or collected by or on behalf of Singapore, including any political subdivision or taxing authority thereof, or the jurisdiction of incorporation or residence of any of our assignees or any of our successors, or any subsidiary, branch, division or other entity through which we may from time to time direct any payments of principal, premium, if any, and interest on the notes or any political subdivision or taxing authority thereof (an "other jurisdiction"). If deduction or withholding of any taxes shall at any time be required by Singapore or any other jurisdiction, we, our assignee or any relevant successor will, subject to timely compliance by the holders or beneficial owners of the relevant notes with any relevant administrative requirements, pay or cause to be paid such additional amounts ("additional amounts") in respect of principal of, premium, if any, or interest, as may be necessary in order that the net amounts paid to the holders of the notes outstanding on the date of the required payment or the trustee under the indenture, as the case may be, pursuant to the indenture, after the deduction or withholding, shall equal the respective amounts that the holder would have received if the taxes had not been withheld or deducted.

However, no additional amounts shall be paid to any holder or beneficial owner for or on account of any of the following:

All references herein to payments of principal of, premium, if any, and interest on the notes shall be deemed to include any additional amounts that may become payable in respect of the notes.

Flex may redeem the notes at its option at any time, either in whole or in part. Flex will, however, pay the interest installment due on any interest payment date that occurs on or before a redemption date to each holder of the notes to be redeemed as of the close of business on the record date immediately preceding that interest payment date.

If Flex elects to redeem the notes, either in whole or in part, prior to , 20 (the date that is months prior to the stated maturity date of the notes) (the "par call date"), it will pay a redemption price equal to the greater of the following amounts, plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date:

If Flex elects to redeem the notes, either in whole or in part, on or after the par call date, it will pay a redemption price equal to 100% of the aggregate principal amount of the notes to be redeemed, plus, in each case, accrued and unpaid interest thereon to, but not including, the redemption date.

In determining the present values of the remaining scheduled payments, Flex will discount such payments to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) using a discount rate equal to the treasury rate plus % ( basis points).

"comparable treasury issue" means the United States Treasury security selected by an independent investment banker as having an actual or interpolated maturity comparable to the remaining term of the notes called for redemption (assuming such notes matured on the par call date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a maturity most nearly equal to the par call date.

"comparable treasury price" means, with respect to any redemption date, (1) the arithmetic average of the reference treasury dealer quotations for such redemption date after excluding the highest and lowest reference treasury dealer quotations, or (2) if Flex obtains fewer than four reference treasury dealer quotations, the arithmetic average of all reference treasury dealer quotations for such redemption date.

"independent investment banker" means an independent investment banking institution of national standing that is a primary U.S. Government securities dealer in New York City appointed by Flex.

"reference treasury dealer" means any four primary U.S. Government securities dealers in New York City selected by Flex.

"reference treasury dealer quotations" means, with respect to each reference treasury dealer and any redemption date, the arithmetic average of the bid and asked prices for the comparable treasury issue (expressed in each case as a percentage of its principal amount) quoted in writing by such reference treasury dealer as of 3:30 p.m., New York City time, on the third business day preceding such redemption date.

"remaining scheduled payments" means, with respect to any note to be redeemed, the remaining scheduled payments of the principal of and premium, if any, and interest thereon that would be due after the related redemption date but for such redemption if the notes matured on the par call date; provided, however, that, if such redemption date is not an interest payment date with respect to such note, the amount of the next scheduled interest payment thereon will be reduced by the amount of interest accrued thereon to such redemption date.

"treasury rate" means, with respect to any redemption date, the rate per annum equal to the semi-annual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the comparable treasury issue. In determining this rate, Flex will assume a price for the comparable treasury issue (expressed as a percentage of its principal amount) equal to the comparable treasury price for such redemption date.

Notice of any redemption will be sent at least 30 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed. If less than all of the notes are to be redeemed, the trustee will select the notes or portions thereof in authorized denominations to be redeemed by lot, pro rata or by any other method customarily authorized by the clearing systems (subject to DTC procedures). The trustee shall promptly notify Flex of the notes or portions thereof selected for redemption and, in the case of any partial redemption, the principal amount thereof to be

redeemed; provided, however, that the principal amount of the notes so selected by the trustee for such partial redemption shall not exceed the principal amount of the notes which Flex has elected to redeem.

Unless Flex defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes, or portions thereof, called for redemption.

We may, at our option, redeem the notes in whole at any time at a redemption price equal to 100% of the principal amount thereof plus accrued and unpaid interest, if any, to the date fixed for redemption (the "tax redemption price") if a change in tax law occurs.

A "change in tax law" is any change in or any amendment to the laws, including any applicable double taxation treaty or convention (or regulation or ruling promulgated thereunder), of Singapore, or any other jurisdiction, as defined under "—Payment of Additional Amounts," or of any political subdivision or taxing authority thereof, affecting taxation, or any change in the application or interpretation or official position regarding the application of such laws, double taxation treaty or convention:

If a change of control repurchase event (as defined below) occurs, unless Flex has exercised its right to redeem the notes as described above, Flex will be required to make an offer to each holder of notes to repurchase all or any part (in minimum denominations of $2,000 and in integral multiples of $1,000 in excess thereof, provided that no note in an unauthorized denomination may remain outstanding after such repurchase) of that holder's notes at a repurchase price in cash equal to 101% of the aggregate principal amount of the notes repurchased plus any accrued and unpaid interest on the notes repurchased to, but not including, the date of repurchase. Within 30 days following any change of control repurchase event or, at the option of Flex, prior to any change of control (as defined below), but after the public announcement of the change of control, Flex will send a notice to each holder, with a copy to the trustee, describing the transaction or transactions that constitute or may constitute the change of control repurchase event and offering to repurchase the notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is sent. The notice shall, if mailed prior to the date of consummation of the change of control, state that the offer to repurchase is conditioned on a change of control repurchase event occurring on or prior to the payment date specified in the notice.

Flex will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a change of control repurchase event. To the extent that the provisions of any securities laws or regulations conflict with the change of control repurchase event provisions of the notes, Flex will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the change of control repurchase event provisions of the notes by virtue of compliance with such securities laws or regulations.

On the repurchase date following a change of control repurchase event, Flex will, to the extent lawful:

The paying agent will disburse to each holder of notes properly tendered the repurchase price for the notes, and Flex shall execute, and the trustee will authenticate and deliver (or cause to be transferred by book-entry) to each holder, a new note equal in principal amount to any unpurchased portion of any notes surrendered.

Flex will not be required to make an offer to repurchase the notes upon a change of control repurchase event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by Flex and such third-party repurchases all notes properly tendered and not withdrawn under its offer.

The change of control repurchase event feature of the notes may in certain circumstances make more difficult or discourage a sale or takeover of Flex and, thus, the removal of incumbent management. The change of control repurchase event feature is a result of negotiations between Flex and the underwriters.

Flex has no present intention to engage in a transaction involving a change of control, although it is possible that Flex could decide to do so in the future. Subject to the limitations discussed below, Flex could, in the future, enter into certain transactions, including acquisitions, refinancings or other recapitalizations, that would not constitute a change of control under the indenture, but that could increase the amount of indebtedness outstanding at such time or otherwise affect the capital structure of Flex or credit ratings of the notes. Restrictions on the ability of Flex and certain of its subsidiaries to incur liens, enter into sale and leaseback transactions and consolidate, merge or sell assets are contained in the covenants as described under "—Certain Covenants—Limitation on Liens," "—Certain Covenants—Limitation on Sale and Leaseback Transactions," and "—Certain Covenants—Merger, Consolidation or Sale of Assets." Except for the limitations contained in such covenants and the covenant relating to repurchases upon the occurrence of a change of control repurchase event, the indenture does not contain any covenants or provisions that may afford holders of the notes protection in the event of a decline in the credit quality of Flex or a highly leveraged or similar transaction involving Flex.

Flex may not have sufficient funds to repurchase all the notes upon a change of control repurchase event. In addition, even if it has sufficient funds, Flex may be prohibited from repurchasing the notes under the terms of other agreements relating to Flex's indebtedness at the time (although Flex currently does not have any agreements precluding such repurchase of the notes).

Flex may from time to time, without notice to, or the consent of, the holders of the notes, increase the principal amount of the notes by issuing additional notes having the same terms and conditions as, and ranking equally and ratably with, the notes in all respects (except for the issue date, the issue price and, if applicable, the initial interest accrual date of such additional notes and the first interest payment date following the issue date of such additional notes). Except as described under "—Modifications and Waivers," the notes and any additional notes will, in each case, be consolidated and form a single series, and will have the same terms as to ranking, redemption, repurchase, waivers, amendments or otherwise, and will vote together as one class on all matters. If any additional notes are not fungible with the notes offered hereby for U.S. federal income tax purposes, they will have one or more separate CUSIP numbers.

Except as set forth below, neither Flex nor any of its subsidiaries will be restricted by the indenture from:

In addition, Flex will not be required to maintain any financial ratios or specified levels of net worth or liquidity or to repurchase or redeem or otherwise modify the terms of any of the notes upon a change of control or other events involving Flex or any of its subsidiaries which may adversely affect the creditworthiness of the notes, except to the limited extent provided under "—Repurchase of Notes Upon a Change of Control Repurchase Event." Among other things, the indenture will not contain covenants designed to afford holders of the notes any protections in the event of a highly leveraged or other transaction involving Flex that may adversely affect holders of the notes, except to the limited extent provided below and under "—Repurchase of Notes Upon a Change of Control Repurchase Event."

Flex will not, and will not permit any restricted subsidiary (as defined below) to create, incur or assume any lien (as defined below) on any property (including shares of capital stock or indebtedness) or assets, whether now owned or hereafter acquired, to secure indebtedness (including guarantees, as defined below) of Flex, any restricted subsidiary, or any other person, including, without limitation, indebtedness under the Credit Facilities, without in any such case effectively providing concurrently with the creation, incurrence or assumption of such lien with respect to such indebtedness that the notes (together with, if Flex so determines, any other indebtedness of Flex or such restricted subsidiary then existing or thereafter created which is not subordinate to the notes) will be secured by any such lien equally and ratably with (or prior to) such secured indebtedness, so long as such secured indebtedness is so secured. In the case of the Credit Facilities, such obligation shall arise concurrently with the grant of any lien thereunder, whether or not any indebtedness will be outstanding under the Credit Facilities at such time. Any lien created for the benefit of the holders of the notes pursuant to this paragraph shall provide by its terms that such lien shall be automatically and unconditionally released and discharged upon the release and discharge of the lien that gave rise to the obligation to secure the notes.

Except in the case of any lien granted under the Credit Facilities, the foregoing restriction will not, however, apply to the following:

Except in the case of any lien granted under the Credit Facilities (as to which no exceptions to the restrictions on liens and the obligation to equally and ratably secure the notes apply), the restriction on liens on property or assets of Flex or any restricted subsidiary contained above will also not apply to the creation, incurrence or assumption by Flex or any restricted subsidiary of a lien which would otherwise be subject to the foregoing restrictions if the aggregate principal amount of all indebtedness secured by liens on property or assets of Flex and of any restricted subsidiary then outstanding (not including any such indebtedness secured by liens permitted to be incurred pursuant to paragraphs (i) through (xxiii) above) plus attributable debt (as defined below) of Flex and its restricted subsidiaries in respect of sale and leaseback transactions, as defined in "—Limitation on Sale and Leaseback Transactions" below, that would otherwise be subject to the restrictions described below under "—Limitation on Sale and Leaseback Transactions" (not including any such sale and leaseback transaction permitted under paragraph (i) in "—Limitation on Sale and Leaseback Transactions" below in reliance on an exception set forth in paragraphs (i) through (xxiii) of this "Limitations on Liens" covenant) does not at the time such indebtedness is incurred exceed an amount equal to 15% of consolidated net tangible assets (as defined below).

For the purposes of determining compliance with this covenant, in the event that a lien meets the criteria of more than one of the types of liens described above, Flex, in its sole discretion, will classify, and may reclassify, such lien and only be required to include the amount and type of such lien in one of the paragraphs (i) through (xxiii) above or the immediately preceding paragraph, and a lien may be divided and classified and reclassified into more than one of the types of liens described above.

For the purposes of the "Limitation on Liens" covenant described above, the creation of a lien to secure a guaranty or to secure indebtedness which existed prior to the creation of such lien, will be deemed to involve indebtedness in an amount equal to the lesser of (x) the fair market value (as determined in good faith by Flex) of the asset subject to such lien and (y) the principal amount guaranteed or secured by such lien, but the amount of indebtedness secured by liens will be computed without cumulating the underlying indebtedness with any guarantee thereof or lien securing the same.

Flex will not, and will not permit any restricted subsidiary to, enter into any arrangement after the date of the original issuance of the notes with any bank, insurance company or other lender or investor (other than Flex or another restricted subsidiary) providing for the leasing by Flex or any such restricted subsidiary for a period of more than three years (other than pursuant to so-called synthetic lease or tax retention operating lease transactions) of any property or assets which (x) at the time of such lease have been or are to be owned by Flex or a restricted subsidiary for more than 180 days and (y) have been or are to be sold or transferred by Flex or such restricted subsidiary to such lender or investor or to any person to whom funds have been or are to be advanced by such lender or investor on the security of such property or assets (a "sale and leaseback transaction"), unless either:

The indenture provides that Flex may not (i) consolidate, merge, combine or amalgamate with or into any other person or convey, transfer or lease its property and assets as an entirety or substantially as an entirety to any other person, or (ii) permit any other person to consolidate, merge, combine or amalgamate with or into Flex, unless:

Restrictions Upon Reincorporating, Merging or Consolidating into a Subject Country

The indenture provides that we may not consolidate or merge with or into, whether or not we are the surviving corporation, or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of our properties or assets in one or more related transactions (a "subject transaction") to another corporation, person or entity unless it satisfies specified conditions. If the surviving or resulting transferee, lessee or successor person (the "successor corporation") in a subject transaction is incorporated in any jurisdiction other than the country of Singapore and the United States of America, or any state thereof or the District of Columbia (any such jurisdiction, a "subject country"), then we must satisfy the conditions specified in the clauses below as promptly as practicable, but no later than 60 days following the date of the subject transaction:

In the event of any subject transaction in which the successor corporation is organized and existing under the laws of a subject country, we will indemnify and hold harmless the holder of each note from and against any and all present and future taxes, levies, imposts, charges and withholdings, including, without limitation, estate, inheritance, capital gains and other similar taxes, and any and all present and future registration, stamp, issue, documentary or other similar taxes, duties, fees or charges, imposed, assessed, levied or collected by or for the account of any jurisdiction or political subdivision or taxing or other governmental agency or authority thereof or therein on or in respect of the notes, the indenture or any other agreement relating to calculations to be performed with respect to the notes or any amount paid or payable under any of the foregoing which, in any such case, would not have been imposed had the subject transaction not occurred.

A substantial portion of our assets is located outside the U.S. and, as described above under "Merger, Consolidation or Sale of Assets" we are permitted to merge into, consolidate with or transfer all or substantially all of our properties and assets to a person domiciled outside the U.S. (although we have no present intention of doing so), subject to the conditions described under such heading. Any judgment obtained in the U.S. against us or any successor person, including judgments with respect to payments on the notes, may not be collectible in the U.S. In addition, there is some doubt as to the enforceability in other countries, in original actions or in actions for enforcement of judgments of U.S. courts, of civil liabilities based solely on the federal securities laws of the U.S., and awards for punitive damages in actions brought in the U.S. or elsewhere may not be enforceable in certain jurisdictions.

At any time that Flex is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, so long as any debt securities (including the notes) issued under the base indenture are outstanding, Flex will furnish to the trustee and make available on its website copies of such annual and quarterly reports and such information, documents and other reports as are required under Sections 13 and 15(d) of the Exchange Act and applicable to a U.S. corporation (and not a foreign private issuer) subject to such provisions, within 15 days after the filing with the SEC of such information, documents and reports under such provisions. Documents filed by us with the SEC via the EDGAR system (or any successor thereto) will be deemed to be filed with the trustee at the time such documents are filed via such system, though the trustee shall have no obligation to determine whether such filings have been made.

Each of the following is an "event of default" under the indenture with respect to the notes:

The indenture provides that the trustee may withhold notice to the holders of the notes of the occurrence of a default with respect to the notes (except a default in payment of principal, premium, if any, or interest, if any) if the trustee considers it in the interest of the holders to do so.

The indenture provides that if an event of default with respect to the notes of the type described in clause (vi) with respect to Flex (but not any of its significant subsidiaries) shall have occurred and be continuing, then the principal of, accrued and unpaid interest on and any additional amounts payable in respect of the notes will become immediately due and payable. The indenture provides that if any other event of default with respect to the notes shall have occurred and be continuing, then, either the trustee or the holders of at least 25% in principal amount of the notes then outstanding may declare the principal amount of all the notes and any accrued and unpaid interest to be due and payable immediately, but upon certain conditions such declaration and its consequences may be rescinded by the holders of a majority in principal amount of the notes.

The trustee is under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders of the notes unless such holders have offered the trustee security or indemnity satisfactory to the trustee. Subject to the foregoing, holders of a majority in aggregate principal amount of the debt securities then outstanding under the base indenture affected (including the affected notes), voting together as a single class, shall have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the base indenture or exercising any trust or power conferred on the trustee with respect to such debt securities. The indenture requires the annual filing with the trustee of a certificate by Flex as to whether or not it is in default under the terms of the indenture. Flex is also required to deliver to the trustee, within five calendar days after becoming aware thereof, written notice of any event of default in respect of any series of notes or any event which after notice or lapse of time or both would constitute an event of default, its status and what actions Flex intends to take in connection therewith.

Notwithstanding any other provision of the indenture, the right of any holder of any note to receive payment of the principal of and premium, if any, and interest, if any, on the notes on or after the respective due dates therefor (as provided for in the notes) and to bring suit for enforcement of any such payment, on or after such respective dates shall not be impaired without the consent of such holder.

"attributable debt" means, as to any particular lease under which any person is at the time of determination liable for a term of more than 12 months, at any date as of which the amount thereof is to be determined, the total net amount of rent required to be paid by such person under such lease during the remaining term thereof (excluding any subsequent renewal or other extension options held by the lessee), discounted from the respective due dates thereof to such date at the interest rate inherent in such lease (such rate to be determined by any two of the following: the Chief Executive Officer, the President, the Chief Financial Officer, any Vice President, the Treasurer, Assistant Treasurer and the Controller of Flex), compounded annually. The net amount of rent required to be

paid under any such lease for any such period should be the aggregate amount of the rent payable by the lessee with respect to such period after excluding amounts required to be paid on account of maintenance and repairs, services, insurance, taxes, assessments, water rates and similar charges and contingent rents (such as those based on sales). In the case of any lease which is terminable by the lessee upon the payment of a penalty, such net amount of rent should include the lesser of (i) the total discounted net amount of rent required to be paid from the later of the first date upon which such lease may be so terminated or the date of the determination of such amount of rent, as the case may be, and (ii) the amount of such penalty (in which event no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated).

"capital stock" means (i) with respect to any person organized as a corporation, any and all shares, interests, rights to purchase, warrants, options, participations or other equivalents of or interest in (however designated) corporate stock, and (ii) with respect to any person that is not organized as a corporation, the partnership, membership or other equity interests or participations in such person.

This "change of control" definition includes a disposition of all or substantially all of the property and assets of Flex and its subsidiaries taken as a whole to any person. Although there is a limited body of case law interpreting the phrase "substantially all," there is no precise established definition of the phrase under applicable law. Accordingly, in certain circumstances there may be a degree of uncertainty as to whether a particular transaction would involve a disposition of "all or substantially all" of the property or assets of a person. As a result, it may be unclear as to whether a change of control has occurred and whether a holder of the notes may require Flex to make an offer to repurchase the notes as described above.

"change of control repurchase event" means the occurrence of both a change of control and a ratings event.

"consolidated net tangible assets" means the total of all assets reflected on the most recent consolidated balance sheet of Flex and its consolidated subsidiaries filed by Flex pursuant to "—SEC Reports," prepared in accordance with generally accepted accounting principles, at their net book values (after deducting related depreciation, depletion, amortization and all other valuation reserves which, in accordance with such principles, should be set aside in connection with the business conducted), but excluding goodwill, unamortized debt discount and all other like intangible assets, all as determined in accordance with such principles, less the aggregate of the current liabilities of Flex and its consolidated subsidiaries reflected on such balance sheet, all as determined in accordance with such principles. For purposes of this definition, "current liabilities" include all indebtedness for money borrowed, incurred, issued, assumed or guaranteed by Flex and its consolidated subsidiaries, and other payables and accruals, in each case payable on demand or due within one year of the date of determination of consolidated net tangible assets, but shall exclude any portion of long-term debt maturing within one year of the date of such determination (which excluded amount includes, for the avoidance of doubt, the portion of such debt maturing during the last year thereof notwithstanding that such debt may then be characterized as short-term debt), all as reflected on such consolidated balance sheet of Flex and its consolidated subsidiaries, prepared in accordance with generally accepted accounting principles.

"consolidated subsidiary" means, at any date, any subsidiary or other entity, the accounts of which would be consolidated with those of Flex in its consolidated financial statements if such statements were prepared as of such date.

"continuing directors" means, as of any date of determination, any member of the board of directors of Flex who (1) was a member of such board of directors on the date of the issuance of the notes; or (2) was nominated for election or elected to such board of directors with the approval of a majority of the continuing directors who were members of such board of directors at the time of such nomination or election.

"Credit Facilities" means, collectively, the Revolving/Term Loan A Facility and the Term Loan B Facility, and any amendment, extension, renewal, increase, decrease, substitution or replacement (other than the notes) of such facilities or any such substitution or replacement, provided however, that the term "Credit Facilities" shall not include any facility which substitutes or replaces the Term Loan B Facility, or any substitutions or replacements thereof.

"currency agreement" means any currency exchange contract, foreign exchange contract, currency swap agreement, cross-currency rate swap agreement, currency options agreement or other similar agreement or arrangement.

"funded debt" means indebtedness created, assumed or guaranteed by a person for money borrowed which matures by its terms, or is renewable by the borrower to a date, more than a year after the date of original creation, assumption or guarantee.

"generally accepted accounting principles" or "U.S. GAAP" means generally accepted accounting principles which were in effect and adopted by Flex during its fiscal year ended March 31, 2019. At any time after the issue date, Flex may elect to apply International Financial Reporting Standards as issued by the International Account Standards Board ("IFRS") in lieu of U.S. GAAP and, upon any such election, references herein to U.S. GAAP or generally accepted accounting principles shall thereafter be construed to mean IFRS on the date of such election; provided that any such election, once made, shall be irrevocable; provided, further, that any calculation or determination in the indenture that requires the application of U.S. GAAP for periods that include fiscal quarters ended prior to Flex's election to apply IFRS shall remain as previously calculated or determined in accordance with U.S. GAAP.

"guarantee" means any obligation, contingent or otherwise, of any person directly or indirectly guaranteeing any indebtedness of any other person and, without limiting the generality of the foregoing, any obligation, direct or indirect, contingent or otherwise, of such person (i) to purchase or pay (or advance or supply funds for the purchase or payment of) such indebtedness of such other person (whether arising by virtue of partnership arrangements, or by agreements to keep well, to purchase assets, goods, securities or services (unless such purchase arrangements are on arm's-length terms and are entered into in the ordinary course of business), to take-or-pay, or to maintain financial statement conditions or otherwise) or (ii) entered into for purposes of assuring in any other manner the obligee of such indebtedness of the payment thereof or to protect such obligee against loss in respect thereof (in whole or in part); provided that the term "guarantee" shall not include endorsements for collection or deposit in the ordinary course of business. The term "guarantee" used as a verb has a corresponding meaning.

"indebtedness" means (a) any liability of Flex or any of its subsidiaries (1) for borrowed money, or under any reimbursement obligation relating to a drawn upon letter of credit or bank guaranty, or (2) evidenced by a bond, note, debenture or similar instrument (other than liabilities for the deferred purchase price of property evidenced by a bond, note, debenture or similar instrument to the extent (i) such liability has a regularly-scheduled maturity date that is less than one year, and (ii) solely for purposes of paragraph (iv) under "Events of Default" above, the non-payment of such liability is subject to a good faith dispute, including by virtue of a bona fide right of set-off), or (3) for payment obligations arising under any conditional sale or other title retention arrangement, purchase money obligation or deferred purchase price arrangement (excluding any purchase price adjustments, earn-out or similar arrangements) made in connection with the acquisition of any businesses, properties or assets of any kind (other than payment obligations consisting of accounts payable for property or the deferred purchase price of property to the extent (i) such payment obligation has a regularly-scheduled maturity date that is less than one year, and (ii) solely for purposes of paragraph (iv) under "Events of Default" above, the non-payment of such payment obligation is subject to a good faith dispute, including by virtue of a bona fide right of set-off), or (4) consisting of the discounted rental stream properly classified in accordance with generally accepted accounting principles on the balance sheet of Flex or any of its subsidiaries, as lessee, as a capitalized lease obligation, or (5) under currency agreements and interest rate agreements (but only the net liability thereunder, if any), to the extent not otherwise included in this definition (other than any currency agreements or interest rate agreements entered into in connection with a bona fide hedging operation that provides offsetting benefits to Flex or any of its subsidiaries); (b) any liability of others of a type described in the preceding clause (a) to the extent that Flex or any of its subsidiaries has guaranteed or is otherwise legally obligated in respect thereof; and (c) any amendment, supplement, modification, deferral, renewal, extension or refunding of any liability of the types referred to in clauses (a) and (b) above. "Indebtedness" shall not be construed to include (x) trade payables or credit on open account to trade creditors incurred in the ordinary course of business (including vendor finance programs), (y) obligations under supply or consignment contracts in the ordinary course of business or forward sales agreements for inventory, or (z) any liability arising from a permitted receivables transaction. Accrual of interest, accretion or amortization of original issue discount will not be deemed to be an incurrence of indebtedness for any purpose hereunder.

"interest rate agreement" means, for any person, any interest rate swap agreement, interest rate cap agreement, interest rate collar agreement or other similar agreement or arrangement.

"investment grade" means a rating of Baa3 or better by Moody's (or its equivalent under any successor rating categories of Moody's); a rating of BBB- or better by S&P (or its equivalent under any successor rating categories of S&P); and the equivalent investment grade credit rating from any additional rating agency or rating agencies selected by Flex.

"lien" means, with respect to any asset, any pledge, mortgage, charge, encumbrance or security interest in respect of such asset; provided that any transaction (including, without limitation, any sale of accounts receivable) which is treated as a sale of assets under U.S. GAAP shall be so treated and any asset which is so sold shall not be deemed subject to a lien. Pursuant to the indenture, a contractual grant of a right of set-off (which may include a security interest granted in the same collateral) or a contractual lien on property in transit to or in the possession of the lienor, does not create a lien in the absence of an agreement to maintain a balance or deliver property against which such right may be exercised.

"permitted receivables transaction" means any transaction or series of transactions entered into by Flex or any of its restricted subsidiaries in order to monetize or otherwise finance receivables, leases, receivables assets or other financial assets (including, without limitation, financing contracts) or other transactions evidenced by receivables purchase agreements, receivables sales agreement, factoring agreements and other similar agreements pursuant to which receivables are sold at a discount (in each case whether now existing or arising in the future), and which may include a grant of a security interest in any such receivables, leases, receivables assets or other financial assets (whether now existing or arising in the future) of Flex or any of its restricted subsidiaries, and any assets related thereto, including all collateral securing such receivables, leases, receivables assets or other financial assets, all contracts and all guarantees or other obligations in respect thereof, proceeds thereof and other assets that are customarily transferred, or in respect of which security interests are customarily granted, in connection with asset securitization transactions or factoring transactions involving receivables, leases, receivables assets or other financial assets or other transactions evidenced by receivables purchase agreements, receivables sales agreement, factoring agreements and other similar agreements pursuant to which receivables are sold at a discount.

"person" means any individual, corporation, partnership, joint venture, limited liability company, joint-stock company, trust, unincorporated organization or government or any agency or political subdivision thereof.

"rating agency" means (1) each of Moody's and S&P; and (2) if Moody's or S&P ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of the control of Flex, a "nationally recognized statistical rating organization" within the meaning of Section 3(a)(62) under the Exchange Act, selected by Flex (as certified by a resolution of the board of directors of Flex) as a replacement agency for Moody's or S&P, as the case may be.

"ratings event" means that the notes cease to be rated by both rating agencies as investment grade on any day within 60 days after the earlier of, (i) the occurrence of a change of control or (ii) public notice of the occurrence of a change of control or the intention by Flex to effect a change of control (which period shall be extended so long as the rating of the notes is under publicly announced consideration for a possible downgrade by any of the rating agencies) (the "trigger period"). If either rating agency is not providing a rating of the notes on any day during the trigger period for any reason, the rating of such rating agency shall be deemed to have ceased to be rated investment grade during the trigger period.

"receivables assets" means accounts receivable, indebtedness and other obligations owed to or owned by Flex or any restricted subsidiary (whether now existing or arising or acquired in the future) arising in the ordinary course of business from the sale of goods or services (including any indebtedness or other obligation constituting an account, chattel paper, instrument or general intangible), together with all related security, collateral, collections, contracts, contract rights, guarantees or other obligations in respect thereof, all proceeds and supporting obligations and all other related assets which are of the type customarily transferred in connection with a sale, factoring, financing or securitization transaction involving accounts receivable.

"restricted subsidiary" means, at any time, each and every subsidiary at least 80% (by number of votes) of the voting equity of which is legally and beneficially owned by Flex or its wholly owned restricted subsidiaries at such time.

"Revolving/Term Loan A Facility" means the Credit Agreement, dated as of June 30, 2017, by and among Flex and certain of its subsidiaries as borrowers, Bank of America, N.A., as Administrative Agent and Swing Line Lender, and the other Lenders party thereto, as amended from time to time.

"S&P" means Standard & Poor's Financial Services LLC, a subsidiary of McGraw-Hill Financial Inc., and its successors.

"significant subsidiary" means any significant subsidiary as defined in Rule 1-02(w) of Regulation S-X promulgated by the SEC.

"subsidiary of Flex" means any corporation, association or other business entity of which at the time of determination Flex or one or more Flex subsidiaries owns or controls more than 50% of the shares of voting equity.

"surety obligations" means any bonds, including bid bonds, advance bonds, or performance bonds, letters of credits, warranties, and similar arrangements between Flex or any of its restricted subsidiaries and one or more surety providers, for the benefit of Flex's or any restricted subsidiary's suppliers, vendors, insurers, or customers including, in each case, any related notes, guarantees, collateral documents, instruments and agreements executed in connection therewith, in each case as amended, modified, renewed, refunded, replaced, restated or refinanced from time to time, and in each case exclusive of obligations for the payment of borrowed money.

"Term Loan B Facility" means the Term Loan Agreement, dated as of November 30, 2016, among Flex, as Borrower, Bank of Tokyo-Mitsubishi UFJ, LTD., as Administrative Agent, and the other Lenders party thereto, as amended on July 25, 2017 and as further amended from time to time.

"voting equity" means stock or equivalent equity interest that ordinarily has voting power for the election of directors, managers or trustees, whether at all times or only so long as no senior class of stock has such voting power by reason of any contingency.

"voting stock" of any specified person as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

"wholly owned restricted subsidiary" means, at any time, any restricted subsidiary, 100% of all of the equity interests (except directors' qualifying shares) and voting interests of which are owned by Flex and/or any one or more of Flex's other wholly owned restricted subsidiaries at such time.

Upon the direction of Flex, the indenture shall cease to be of further effect (subject to the survival of certain provisions thereof, including Flex's obligation to pay additional amounts and certain rights of the trustee) when (i) either (a) all of the outstanding notes have been delivered to the trustee for cancellation (subject to certain exceptions) or (b) all of the notes have become due and payable or will become due and payable at their stated maturity within one year or are to be called for redemption within one year and Flex has irrevocably deposited with the trustee, in trust, funds in U.S. dollars, in an amount sufficient to pay the entire indebtedness on the notes in respect of principal (and premium, if any) and interest to the date of such deposit (if the notes have become due and payable) or to the maturity or redemption of the notes, as the case may be, (ii) Flex has paid or deposited funds for the payment of all other sums payable under the indenture with respect to the notes and (iii) certain other conditions are met. Flex will remain obligated, following such deposit, to pay additional amounts to the extent that the amount thereof exceeds the amount deposited in respect of such additional amounts as aforesaid.

The indenture provides that Flex may elect either to defease and be discharged from (i) any and all obligations with respect to the notes (except for, among other things, the obligation to pay additional amounts, if any, upon the occurrence of certain events of taxation, assessment or governmental charge with respect to payments on the notes to the extent that the amount thereof exceeds the amount deposited in respect of such additional amounts as provided below, the obligations to register the transfer or exchange of the notes, to replace temporary or mutilated, destroyed, lost or stolen notes, and to maintain an office or agency in respect of the notes, and the obligation to pay the trustee's fees and expenses and indemnify the trustee) ("defeasance") or (ii) certain restrictive covenants, if any, in the indenture, and any omission to comply with such obligations shall not constitute a default or an event of default ("covenant defeasance"), in either case upon the irrevocable deposit with the trustee, in trust for such purpose, of an amount, in U.S. dollars, and/or government obligations, as defined below, which through the payment of principal and interest in accordance with their terms will provide money, in an amount sufficient to pay the principal of and any premium and any interest on (and, to the extent that (x) the notes provide for the payment of additional amounts and (y) the amount of any such additional amounts is at the time of deposit reasonably determinable by Flex (in the exercise of its sole discretion), any such additional amounts with respect to) the notes, and any mandatory payments thereon, on the scheduled due dates therefor or, the applicable redemption date, as the case may be.

Such a trust may only be established if, among other things, (i) the applicable defeasance or covenant defeasance does not result in a breach or violation of, or constitute a default under, the indenture or any other material agreement or instrument to which Flex is a party or by which it is bound, (ii) no event of default or event which with notice or lapse of time or both would become an event of default shall have occurred and be continuing on the date of establishment of such a trust and, with respect to defeasance only, at any time during the period ending on the 123rd day after such date and (iii) Flex has delivered to the trustee an opinion of counsel (as specified in the indenture) to the effect that the beneficial owners of the notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred, and such opinion of counsel, in the case of defeasance, must refer to and be based upon a letter ruling of the Internal Revenue Service received by Flex, a Revenue Ruling published by the Internal Revenue Service or a change in applicable U.S. federal income tax law occurring after the date of the indenture.

"government obligations" means notes which are (i) direct obligations of the U.S. where the payment or payments thereunder are supported by the full faith and credit of the U.S. or (ii) obligations of a person controlled or supervised by and acting as an agency or instrumentality of the U.S. where the timely payment or payments thereunder are unconditionally guaranteed as a full faith and credit obligation by the U.S., and which, in the case of (i) or (ii), are not callable or redeemable at the option of the issuer or issuers thereof and shall also include a depository receipt issued by a bank or trust company as custodian with respect to any such government obligation or a specific payment of interest on or principal of or other amount with respect to any such government obligation held by such custodian for the account of the holder of a depository receipt, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depository receipt from any amount received by the custodian in respect of the government obligation or the specific payment of interest on or principal of or other amount with respect to the government obligation evidenced by such depository receipt.

The indenture contains provisions permitting Flex and the trustee thereunder, with the consent of the holders of at least a majority in principal amount of the debt securities outstanding under the base

indenture affected (including the notes), voting together as a single class, to modify or amend any of the provisions of the indenture and the notes, provided that no such modification or amendment shall, without the consent of the holder of each outstanding note issued under the indenture so affected, among other things:

The indenture also contains provisions permitting Flex and the trustee, without the consent of the holders of the notes (or any other debt security outstanding under the base indenture), to modify or amend the indenture in order, among other things:

The holders of a majority in aggregate principal amount of the debt securities outstanding under the base indenture affected (including the notes), voting together as a single class, may, on behalf of all holders of such debt securities, waive any past default under the indenture with respect to the notes (or other debt securities) and its consequences, except a default in the payment of the principal of, or premium, if any, or interest, if any, on, or any additional amounts with respect to the notes (or other series of debt securities) or in respect of a covenant or provision which cannot be modified or amended without the consent of each holder of outstanding notes (or other debt securities).

The notes will be issued in registered form, without interest coupons, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, in the form of both global notes and certificated notes, as further provided below.

The trustee is not required (i) to issue, register the transfer of or exchange any note for a period of 15 days before the selection of notes pursuant to a notice of redemption or offer to purchase of notes to be redeemed or purchased pursuant to an offer to purchase the notes, (ii) to register the transfer of or exchange any note so selected for redemption or purchase in whole or in part, except, in the case of a partial redemption or purchase, that portion of the note not being redeemed or purchased, or (iii) if a redemption or a purchase pursuant to an offer to purchase the notes is to occur after a regular record date but on or before the corresponding interest payment date, to register the transfer or exchange of any note on or after the regular record date and before the date of redemption or purchase.

No service charge will be imposed in connection with any transfer or exchange of any note, but Flex may in general require payment of a sum sufficient to cover any transfer tax or similar governmental charge payable in connection therewith.

Global notes will be deposited with a custodian for DTC, and registered in the name of a nominee of DTC. Beneficial interests in the global notes will be shown on records maintained by DTC and its direct and indirect participants. So long as DTC or its nominee is the registered owner or holder of a global note, DTC or such nominee will be considered the sole owner or holder of the notes represented by such global note for all purposes under the indenture and the notes. No owner of a beneficial interest in a global note will be able to transfer such interest except in accordance with DTC's applicable procedures and the applicable procedures of its direct and indirect participants.

Flex will apply to DTC for acceptance of the global notes in its book-entry settlement system. Investors may hold their beneficial interests in the global notes directly through DTC if they are participants in DTC, or indirectly through organizations which are participants in DTC.

Payments of principal and interest under each global note will be made to DTC or its nominee as the registered owner of such global note. Flex expects that the nominee, upon receipt of any such payment, will immediately credit DTC participants' accounts with payments proportional to their respective beneficial interests in the principal amount of the relevant global note as shown on the records of DTC. Flex also expects that payments by DTC participants to owners of beneficial interests will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. Such payments will be the responsibility of such participants, and none of Flex, the trustee, the custodian or any paying agent or registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial interests in any global note or for maintaining or reviewing any records relating to such beneficial interests.

Unless and until they are exchanged, in whole or in part, for notes in certificated form in accordance with the terms of the notes, the notes may not be transferred except (1) as a whole by DTC to a nominee of DTC or (2) by a nominee of DTC to DTC or another nominee of DTC or (3) by DTC or any such nominee to a successor of DTC or a nominee of such successor.

Flex will issue notes to you or your nominees, in fully certificated registered form, rather than to DTC or its nominees, only if:

The indenture will require that payments in respect of the notes represented by the global notes be made by wire transfer of immediately available funds to the accounts specified by holders of the global notes. With respect to notes in certificated form, Flex will make all payments by wire transfer of immediately available funds to the accounts specified by the holders thereof or, if no such account is specified at least 15 days prior to the applicable date for such payment, by mailing a check to the applicable holder's registered address as set forth in the note register.

The notes represented by the global notes are expected to be eligible to trade in DTC's Same-Day Funds Settlement System, and any permitted secondary market trading activity in such notes will, therefore, be required by DTC to be settled in immediately available funds. Flex expects that secondary trading in any certificated notes will also be settled in immediately available funds.

U.S. Bank National Association is the trustee under the indenture and has also been appointed by Flex to act as registrar, transfer agent and paying agent for the notes.

This summary is of a general nature and is included in this prospectus supplement solely for informational purposes. It is not intended to be, nor should it be construed as being, legal or tax advice. No representation regarding the consequences to any particular purchaser of the notes is made. Prospective purchasers should consult their own tax advisers regarding their particular circumstances and the effects of state, local or foreign, including Singapore, tax laws to which they may be subject.

The following discussion is a general summary of certain United States federal income tax consequences of owning and disposing of the notes that may be relevant to holders of the notes purchased in this offering at the issue price, which we assume will be the price indicated on the cover of this prospectus supplement. This discussion is not a complete analysis or description of all of the possible tax consequences of such transactions and does not address all tax considerations that might be relevant to particular holders in light of their personal circumstances or to persons that are subject to special tax rules, including, but not limited to: dealers in securities or currencies, traders in securities that elect to use a mark-to-market method of accounting for their securities holdings, banks, financial institutions, insurance companies, tax-exempt organizations, partnerships or other pass-through entities (or persons that hold the notes through partnerships or other pass-through entities), persons subject to alternative minimum tax, individual retirement and other deferred accounts, persons that own the notes as part of a hedge, a straddle, conversion, constructive sale or other integrated transaction for tax purposes, persons required for U.S. federal income tax purposes to conform the timing of income accruals with respect to the notes to their financial statements under section 451 of the Code, holders whose functional currency for U.S. federal income tax purposes is not the U.S. dollar, or U.S. expatriates.

As used herein, the term "U.S. holder" means a beneficial owner of a note, who is, for U.S. federal income tax purposes: (1) an individual citizen or resident of the United States, (2) a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (3) an estate the income of which is subject to U.S. federal income tax regardless of its source, or (4) a trust (A) if a court within the United States is able to exercise primary supervision over its administration and one or more U.S. persons have authority to control all substantial decisions of the trust, or (B) that has a valid election in effect under applicable Treasury Regulations to be treated as a U.S. person for U.S. federal income tax purposes (for purposes of this discussion, "U.S. holders"). As used herein, the term "Non-U.S. holder" is any holder that is not a U.S. holder. If an entity taxable as a partnership (or other "pass-through" entity) for U.S. federal income tax purposes holds the notes, the U.S. federal income tax treatment of a partner (or other owner) will depend on the status of the partner (or other owner) and the activities of the entity. Such partner (or other owner) is encouraged to consult its own tax advisors regarding the ownership and disposition of the notes.

This discussion is directed solely at holders that hold their notes as capital assets and who acquire notes in this offering at the initial offering price. This discussion is based on the provisions of the United States Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations, published rulings and court decisions, all as currently in effect. These laws are subject to change, possibly on a retroactive basis. Any of the authorities on which this discussion is based could be changed in a material and adverse manner at any time, and any such change could be applied on a retroactive or prospective basis, which could affect the U.S. federal income tax considerations described in this section. This discussion does not address the potential effects, whether adverse or beneficial, of any proposed legislation that, if enacted, could be applied on a retroactive or prospective basis. This section does not discuss any tax consequences arising under the U.S. federal estate and gift tax laws or the laws of any state, local or other taxing jurisdiction.

THE SUMMARY OF U.S. FEDERAL INCOME TAX CONSEQUENCES SET OUT BELOW IS FOR GENERAL INFORMATION ONLY. ALL PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR TAX ADVISERS AS TO THE PARTICULAR TAX CONSEQUENCES TO THEM OF OWNING AND DISPOSING OF THE NOTES, INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL, NON-U.S. AND OTHER TAX LAWS AND POSSIBLE CHANGES IN TAX LAW.

The gross amount of interest and any additional amounts paid on the notes generally will be includable in the gross income of a U.S. holder as ordinary interest income in accordance with such holder's method of accounting. Interest and any additional amounts generally will constitute income from sources outside the United States. It is expected and this disclosure assumes that the notes will be issued without original issue discount for U.S. federal income tax purposes. Subject to generally applicable limitations, a U.S. holder may elect to claim either a deduction or foreign tax credit in computing its U.S. federal income tax liability for withholding taxes, if any, withheld from interest paid with respect to the notes. Prospective purchasers should consult their tax advisers concerning the applicability of the foreign tax credit and source of income rules to income attributable to the notes.

There are circumstances in which we might be permitted or required to accelerate payments on the notes, including pursuant to an offer to repurchase notes, and circumstances in which we might be required to pay amounts in excess of stated interest or principal on the notes, for instance, as described in "Description of Notes—Repurchase of Notes Upon a Change of Control Repurchase Event." We intend to take the position that the possibility of such acceleration and additional payments will not cause the notes to be treated as contingent payment debt instruments for U.S. federal income tax purposes. Our position is not binding on the Internal Revenue Service ("IRS"). The IRS may take a contrary position to this position and may treat the notes as contingent payment debt instruments under the applicable Treasury Regulations, which could affect the timing and character of income, gain or loss from holding or disposing of the notes. If the IRS were to successfully assert a contrary position, a U.S. holder may be required to accrue income on its notes in excess of stated interest, and to treat as ordinary income rather than capital gain any income realized on the taxable disposition of a note before the resolution of the contingencies. The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments for U.S. federal income tax purposes. U.S. holders should consult their independent tax advisors concerning this position.

Upon the sale, exchange, or other taxable disposition of a note, a U.S. holder will recognize taxable gain or loss equal to the difference, if any, between the amount realized on such disposition (except to the extent any amount realized is attributable to accrued but unpaid stated interest, which will be taxable as interest income to the extent not previously included in income) and the U.S. holder's tax basis in the note. A U.S. holder's initial tax basis in a note will equal the amount such holder paid for the note. A U.S. holder's adjusted basis in a note generally will be its cost decreased by any payment on the note other than payments of stated interest. Generally, such gain or loss will be treated as long-term capital gain or loss if the note has been held for more than one year at the time of the disposition of the note. Net long-term capital gains of non-corporate U.S. holders, including individuals, currently are eligible for reduced rates of taxation. The deductibility of capital losses is subject to limitations.

Certain individuals, estates and trusts whose income exceeds certain thresholds will be required to pay a 3.8% tax on "net investment income" including, among other things, interest and net gain from disposition of property (other than property held in a trade or business). U.S. holders are encouraged to consult with their own tax advisors regarding the effect, if any, of this tax on their ownership and disposition of the notes.

Individuals may be required to report their holding of certain foreign financial assets, including debt of foreign entities and accounts maintained in a foreign financial institution, if the aggregate value of all of these assets exceeds U.S. $50,000 or other applicable thresholds. The notes are expected to constitute foreign financial assets subject to these requirements unless the notes are held in an account at a domestic financial institution. U.S. holders should consult their tax advisors regarding the application of this reporting requirement.

Non-U.S. holders will generally not be subject to U.S. federal income tax on payments of interest and additional amounts with respect to the notes, unless such interest and additional amounts are effectively connected to such holder's U.S. trade or business (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment maintained by such non-U.S. holder) and certain other conditions are met. A Non-U.S. holder will generally not be subject to U.S. federal income tax on any gain realized on the sale, exchange or disposition of a note unless (i) the gain is effectively connected with such holder's trade or business in the U.S. (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment maintained by such non-U.S. holder), or (ii) if the holder is an individual, such holder is present in the United States for 183 days or more in the taxable year of the sale, exchange or disposition and certain other conditions are met.

Payments with respect to the notes (for example, principal, interest and proceeds from the sale of the notes) may be subject to information reporting to the IRS and U.S. backup withholding. Generally, information reporting and backup withholding will apply to payments on the notes to noncorporate beneficial owners of the notes made by mail or wire transfer to an address in the United States or made by a paying agent, broker or other intermediary in the United States. Certain holders (including corporations) are not subject to backup withholding. U.S. holders will generally be subject to information reporting and backup withholding if such holder is not otherwise exempt and any of the following conditions exist: (1) such holder fails to furnish its taxpayer identification number, or TIN, which, for an individual, is ordinarily his or her social security number; (2) the IRS notifies the payor that such holder furnished an incorrect TIN; (3) the payor is notified by the IRS that such holder is subject to backup withholding because the holder has previously failed to properly report payments of interest or dividends; or (4) such holder fails to certify, under penalties of perjury, that it has furnished a correct TIN and that the IRS has not notified such holder that it is subject to backup withholding. Non-U.S. holders may be subject to information reporting and backup withholding unless they comply with applicable certification procedures to establish that they are not U.S. persons.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a U.S. holder will be allowed as a credit against such holder's U.S. federal income tax liability and may entitle such holder to a refund, provided that the required information is timely furnished to the IRS.

The Foreign Account Tax Compliance Act, or FATCA, imposes a withholding tax on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on payments of interest on, or (subject to the proposed regulations discussed below) gross proceeds from the sale or other disposition of, a note paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any "substantial United States owners" (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain "specified United States persons" or "United States-owned foreign entities" (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and other IRS guidance, withholding under FATCA generally applies to payments of interest on a note regardless of when such payments are made. These rules were set to apply to gross proceeds from certain types of property as of January 1, 2019 but the IRS and U.S. Treasury have released proposed regulations providing that these rules will not apply to any gross proceeds. The proposed regulations may presently be relied on. If we determine withholding is appropriate with respect to the notes, we will withhold tax at the applicable statutory rate, and we will not pay any additional amounts in respect of such withholding.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in the notes.

The following summary addresses only the income tax laws of the Republic of Singapore in force and effect as of the date hereof and is intended as a general guide only. The statements below are general in nature and are based on certain aspects of current tax laws in Singapore in force as at the date of this prospectus supplement and are subject to any changes in such laws, or the interpretation of those laws, occurring after such date, which changes could be made on a retroactive basis. Neither these statements nor any other statements in this prospectus supplement are intended or are to be regarded as advice on the tax position of any holder of the notes or of any person acquiring, selling or otherwise dealing with the notes or on any tax implications arising from the acquisition, sale or other dealings in respect of the notes. The statements made herein do not purport to be a comprehensive or exhaustive description of all the tax considerations that may be relevant to a decision to subscribe for, purchase, own or dispose of the notes and do not purport to deal with the tax consequences applicable to all categories of investors, some of which (such as dealers in securities) may be subject to special rules. Prospective holders of the notes are advised to consult their own tax advisors as to the Singapore or other tax consequences of the acquisition, ownership of or disposal of the notes, including, in particular, the effect of any foreign, state or local tax laws to which they are subject. It is emphasized that none of us, the joint book-running managers and any other persons involved with the offering of the notes accepts responsibility for any tax effects or liabilities resulting from the subscription for, purchase, holding or disposal of the notes.

Subject to the provisions of any applicable tax treaty (there is currently no tax treaty between Singapore and the United States), non-resident taxpayers, namely individuals not residing in, or corporations not managed and controlled in Singapore, which derive income under Section 12(6) of the Income Tax Act, Chapter 134 of Singapore ("ITA") (which includes interest, commissions, fees or other payments in connection with any loan or indebtedness) ("interest") from Singapore, are subject to a withholding tax on that income at a rate of 15%, subject to some exceptions. Interest payments made by us under the notes will not be subject to withholding tax in Singapore if:

We intend to make interest payments through our Bermuda branch. Accordingly, such interest payments under the notes will not be subject to withholding tax in Singapore, as long as such interest payments are not borne, directly or indirectly, by a Singapore Person and are not deductible against income derived from Singapore and the proceeds of the notes are not brought into or used in Singapore.

Singapore does not impose tax on capital gains (i.e., gains which are considered to be capital in nature) but imposes tax on income. Hence, any gains considered to be in the nature of capital made from the sale or disposal of the notes will not be taxable in Singapore. However, any gains from such sale or disposal of the notes which are gains from any trade, business, profession or vocation carried on by that person, if accruing in or derived from Singapore, may be taxable as such gains are considered revenue in nature.

In addition, holders of the notes who apply, or who are required to apply, the Singapore Financial Reporting Standard 39—Financial Instruments: Recognition and Measurement ("FRS 39"), Financial Reporting Standard 109—Financial Instruments ("FRS 109") or Singapore Financial Reporting Standard (International) 9 ("SFRS(I) 9") (as the case may be) for the purposes of Singapore income tax may be required to recognize gains or losses (not being gains or losses in the nature of capital) in accordance with the provisions of FRS 39, FRS 109 or SFRS(I) 9 (as the case may be) (as modified by the applicable provisions of Singapore income tax law) even though no sale or disposal of the notes is made. Please see the section below on "Adoption of FRS 39, FRS 109 or SFRS(I) 9 for Singapore Income Tax Purposes."

Section 34A of the ITA provides for the tax treatment for financial instruments in accordance with FRS 39 (subject to certain exceptions and "opt-out" provisions) to taxpayers who are required to comply with FRS 39 for financial reporting purposes. The Inland Revenue Authority of Singapore ("IRAS") has also issued a circular entitled "Income Tax Implications Arising from the Adoption of FRS 39—Financial Instruments: Recognition & Measurement."

FRS 109 or SFRS(I) 9 (as the case may be) is mandatorily effective for annual periods beginning on or after 1 January 2018, replacing FRS 39. Section 34AA of the ITA requires taxpayers who comply or who are required to comply with FRS 109 or SFRS(I) 9 for financial reporting purposes to calculate

their profit, loss or expense for Singapore income tax purposes in respect of financial instruments in accordance with FRS 109 or SFRS(I) 9 (as the case may be), subject to certain exceptions. The IRAS has also issued a circular entitled "Income Tax: Income Tax Treatment Arising from Adoption of FRS 109—Financial Instruments."

Holders of the notes who may be subject to the tax treatment under Sections 34A or 34AA of the ITA should consult their own accounting and tax advisers regarding the Singapore income tax consequences of their acquisition, holding or disposal of the notes.

We intend to make interest payments through our Bermuda branch. There is no income or other tax in Bermuda imposed by withholding or otherwise on any payment to be made to or by us pursuant to this offering.

This offering will not be subject to ad valorem stamp duty in Bermuda, and no registration, documentary, recording, transfer or other similar tax, fee or charge is payable in Bermuda in connection with the execution, delivery, filing, registration or performance pursuant to this offering.

Subject to the terms and conditions contained in an underwriting agreement, dated the date of this prospectus supplement between us and the underwriters named below, for whom J.P. Morgan Securities LLC, Citigroup Global Markets Inc. and BNP Paribas Securities Corp. are acting as representatives, we have agreed to sell to each of the underwriters, and each underwriter has agreed, severally and not jointly, to purchase from us, the principal amount of notes set forth opposite its name below.

The underwriters are offering the notes subject to their acceptance of the notes from us and subject to prior sale. The underwriting agreement provides that the obligations of the underwriters to pay for and accept delivery of the notes offered by this prospectus supplement are subject to certain conditions. The underwriters are obligated to take and pay for all of the notes offered by this prospectus supplement if any such notes are taken.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. In addition, the underwriters propose initially to offer the notes to certain dealers at a price that represents a concession not in excess of % of the principal amount of the notes. The underwriters may allow, and any such dealer may reallow, a concession not in excess of % of the principal amount of the notes to certain other dealers. After the initial offering of the notes, the underwriters may from time to time vary the offering prices and other selling terms. The underwriters may offer and sell notes through certain of their affiliates.

The following table shows the underwriting discount that we will pay to the underwriters in connection with the offering of the notes:

Expenses associated with this offering to be paid by us, other than the underwriting discount, are estimated to be approximately $ million.

We have also agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.

The notes are a new issue of securities, and there is currently no established trading market for the notes. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so. The underwriters may discontinue any market making in the notes at any time in their sole discretion. Accordingly, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices you receive when you sell will be favorable.

We expect to deliver the notes against payment therefor on or about the date specified in the last paragraph of the cover page of this prospectus supplement, which will be the fifth business day

following the date of the pricing of the notes. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes prior to the second business day preceding the settlement date will be required, by virtue of the fact that the notes initially will settle in T+5, to specify alternative settlement arrangements to prevent a failed settlement.

In connection with this offering of the notes, the underwriters may engage in overallotments, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the aggregate principal amount of notes offered pursuant to this prospectus supplement, which creates a syndicate short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the market prices of the notes to be higher than they would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

From time to time in the ordinary course of their respective businesses, the underwriters and their respective affiliates have engaged in and may in the future engage in commercial banking, derivatives and/or financial advisory, investment banking and other commercial transactions and services with us and our affiliates for which they have received or will receive customary fees and commissions. For example, affiliates of certain of the underwriters are lenders or agents under certain of our term loans and our revolving credit facility.

In addition, from time to time, certain of the underwriters or their respective affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and for persons or entities who have relationships with us, and may do so in the future. The underwriters or their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments. In addition, certain underwriters or their affiliates hold a portion of our 2020 Notes. To the extent that any of the underwriters or their respective affiliates tender the 2020 Notes held by them and have them accepted for purchase in the Tender Offer or hold 2020 Notes that are redeemed in the 2020 Notes Redemption, they may receive a portion of the net proceeds of this offering. Further, the representatives and/or their respective affiliates are acting as the dealer managers in the Tender Offer and may receive fees in connection therewith.

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area ("EEA"). For these purposes, a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU (as amended, "MiFID II"); or (ii) a customer within the meaning of Directive 2002/92/EC (as amended, the "Insurance Mediation Directive"), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Directive 2003/71/EC (as amended, the "Prospectus Directive"). Consequently, no key information document required by Regulation (EU) No 1286/2014 (as amended, the "PRIIPs Regulation") for offering or selling the notes

or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation. This prospectus supplement has been prepared on the basis that any offer of notes in any Member State of the EEA will be made pursuant to an exemption under the Prospectus Directive from the requirement to publish a prospectus for offers of the notes. Neither this prospectus supplement nor the accompanying prospectus is a prospectus for the purposes of the Prospectus Directive.

The notes may be sold only to purchasers purchasing, or deemed to be purchasing, as principal that are accredited investors, as defined in National Instrument 45-106 Prospectus Exemptions or subsection 73.3(1) of the Securities Act (Ontario), and are permitted clients, as defined in National Instrument 31-103 Registration Requirements, Exemptions and Ongoing Registrant Obligations. Any resale of the notes must be made in accordance with an exemption from, or in a transaction not subject to, the prospectus requirements of applicable securities laws.

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement or the accompanying prospectus (including any amendment thereto) contains a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser's province or territory. 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.

Each underwriter (i) has not offered or sold and will not offer or sell in Hong Kong, by means of any document, any notes other than (a) to "professional investors" as defined in the Securities and Futures Ordinance (Cap. 571) of Hong Kong (the "SFO") and any rules made under that Ordinance; or (b) in other circumstances which do not result in the document being a "prospectus" as defined in the Companies (Winding Up and Miscellaneous Provisions) Ordinance (Cap. 32) of Hong Kong or which do not constitute an offer to the public within the meaning of that Ordinance; and (ii) has not issued or had in its possession for the purposes of issue, and will not issue or have in its possession for the purposes of issue, whether in Hong Kong or elsewhere, any advertisement, invitation or document relating to the notes, which is directed at, or the contents of which are likely to be accessed or read by,

the public of Hong Kong (except if permitted to do so under the securities laws of Hong Kong) other than with respect to the notes which are or are intended to be disposed of only to persons outside Hong Kong or only to "professional investors" as defined in the SFO and any rules made under that Ordinance.

The notes have not been and will not be registered pursuant to Article 4, Paragraph 1 of the Financial Instruments and Exchange Act. Accordingly, none of the notes nor any interest therein may be offered or sold, directly or indirectly, in Japan or to, or for the benefit of, any "resident" of Japan (which term as used herein means any person resident in Japan, including any corporation or other entity organized under the laws of Japan), or to others for re-offering or resale, directly or indirectly, in Japan or to or for the benefit of a resident of Japan, except pursuant to an exemption from the registration requirements of, and otherwise in compliance with, the Financial Instruments and Exchange Act and any other applicable laws, regulations and ministerial guidelines of Japan in effect at the relevant time.

Neither this prospectus supplement nor the accompanying prospectus has been, and neither will be, registered as a prospectus with the Monetary Authority of Singapore.

Except for historical information, certain matters contained or incorporated by reference in this prospectus and any accompanying prospectus supplement are, or may be deemed to be forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. The words "will," "may," "designed to," "believe," "should," "anticipate," "plan," "expect," "intend," "estimate" and similar expressions identify forward-looking statements, which speak only as of the date they were made. Because these forward-looking statements are subject to risks and uncertainties, actual results could differ materially from the expectations expressed in the forward-looking statements. Important factors that could cause actual results to differ materially from the expectations reflected in the forward-looking statements include the risks identified in any accompanying prospectus supplement and those described in Item 1A, "Risk Factors" and Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" in our 2017 10-K, as updated by our First Quarter 2018 10-Q, Second Quarter 2018 10-Q and Third Quarter 2018 10-Q and by annual, quarterly and other reports and documents we file with the SEC after the date of this prospectus and that are incorporated by reference herein or in the applicable prospectus supplement. In addition, new risks emerge from time to time and it is not possible for management to predict all such risk factors or to assess the impact of such risk factors on our business. Given these risks and uncertainties, the reader should not place undue reliance on these forward-looking statements. We claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 for our forward-looking statements. We disclaim any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise, except as required by law.

Although we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law, you are advised to consult any additional disclosures we make in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K filed with the SEC. See "Where You Can Find More Information."

ENFORCEMENT OF CIVIL LIABILITIES UNDER UNITED STATES FEDERAL SECURITIES LAWS

We are incorporated in Singapore under the Companies Act, Chapter 50 of Singapore (the "Singapore Companies Act"). Some of our officers and directors reside outside the United States and a substantial portion of our assets are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon us or to enforce against us in United States courts judgments obtained in such courts predicated upon the civil liability provisions of the federal securities laws of the United States. Judgments of United States courts based upon the civil liability provisions of the federal securities laws of the United States are not directly enforceable in Singapore courts and there can be no assurance as to whether Singapore courts will enter judgments in original actions brought in Singapore courts based solely upon the civil liability provisions of the federal securities laws of the United States.

There is uncertainty as to whether judgments of courts in the United States based upon the civil liability provisions of the federal securities laws of the United States would be recognized or enforceable in Singapore courts, and there is doubt as to whether Singapore courts would enter judgments in original actions brought in Singapore courts based solely upon the civil liability provisions of the federal securities laws of the United States. A final and conclusive judgment in the federal or state courts of the United States under which a fixed sum of money is payable, other than a sum payable in respect of taxes, fines, penalties or similar charges, may be subject to enforcement proceedings as a debt in the courts of Singapore under the common law doctrine of obligation. In addition, Singapore courts would not recognize or enforce judgments against us, our directors and officers to the extent that the judgment is punitive or penal. It is uncertain as to whether a judgment of

the courts of the United States under the civil liability provisions of the federal securities law of the United States would be determined by the Singapore courts to be or not be punitive or penal in nature. Such a determination has yet to be made by any Singapore court. The Singapore courts also may not recognize or enforce a foreign judgment if the foreign judgment is inconsistent with a prior local judgment, contravenes public policy, or amounts to the direct or indirect enforcement of a foreign penal, revenue or other public law.

Our business is subject to uncertainties and risks. You should carefully consider and evaluate all of the information included and incorporated by reference in this prospectus, including the risk factors incorporated by reference from, and discussed in Part I, "Item 1A. Risk Factors" in our 2017 10-K, as updated by our First Quarter 2018 10-Q, Second Quarter 2018 10-Q and Third Quarter 2018 10-Q and other filings we make with the SEC. It is possible that our business, financial condition, liquidity or results of operations could be materially adversely affected by any of these risks. The applicable prospectus supplement for any securities we may offer and any applicable free writing prospectus may contain a discussion of additional risks applicable to an investment in us and the particular type of securities we are offering under that prospectus supplement. The risks described in our filings with the SEC, the applicable prospectus supplement or any applicable free writing prospectus are not the only risks facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be not material also may materially and adversely affect our business, financial condition and/or operating results.

Unless otherwise indicated in the applicable prospectus supplement and/or free writing prospectus, we will use the net proceeds from the sale of our securities offered by this prospectus for general corporate and working capital purposes. Pending these uses, we may invest the net proceeds temporarily. If we decide to use the net proceeds from a particular offering of securities for a specific purpose, we will describe that purpose in the applicable prospectus supplement and/or free writing prospectus.

We will not receive any proceeds from sales of securities offered by any selling securityholders under this prospectus.

For purposes of calculating the ratio of earnings to fixed charges, earnings is the amount resulting from (1) adding (a) pretax income from continuing operations, before adjustment for income or loss from equity investees, (b) fixed charges, (c) amortization of capitalized interest and (d) distributed income of equity investees and (2) subtracting interest capitalized. For purposes of calculating the ratio of earnings to fixed charges, fixed charges is the sum of (x) interest expensed and capitalized, (y) amortized premiums, discounts and capitalized expenses related to indebtedness and (z) an estimate of interest within rental expense. Our ratio of earnings to fixed charges was as follows for the respective periods indicated:

The following description of our ordinary shares, together with the additional information we include in any applicable prospectus supplement, summarizes the material terms and provisions of the ordinary shares that we may offer from time to time pursuant to this prospectus. While the terms we have summarized below will apply generally to any future ordinary shares that we and certain securityholders may offer, we will describe the particular terms of any offering in more detail in the applicable prospectus supplement. The following description of our ordinary shares and provisions of our Constitution are summaries and are qualified in its entirety by reference to applicable Singapore law and our Constitution, a copy of which has been filed as Exhibit 3.01 to our Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2016 filed with the SEC on October 31, 2016. A copy of our Constitution is also available for inspection at our registered office in Singapore.

References to "Flex," "we," "us" and "our" in this "Description of Ordinary Shares" are only to Flex Ltd. and not to any of its subsidiaries.

Our share capital consists of ordinary shares, with no par value per ordinary share. There is no authorized share capital under Singapore law. There is a provision in our Constitution to enable us to issue shares with preferred, deferred or other special rights or such restrictions whether in regard to dividend, voting, return of capital or otherwise as our directors may determine, subject to the provisions of the Singapore Companies Act and every other act for the time being in force concerning companies and affecting our company (collectively, the "Statutes") and our Constitution and without prejudice to any special right previously conferred on the holders of any existing shares or class of shares. All ordinary shares presently issued are fully paid and existing shareholders are not subject to any calls on ordinary shares. All ordinary shares are in registered form. We cannot, except in the circumstances permitted by the Singapore Companies Act, grant any financial assistance for the acquisition or proposed acquisition of our own ordinary shares.

Under applicable Singapore law and our Constitution, new shares may be issued only with the prior approval from our shareholders in a general meeting. General approval may be sought from our shareholders in a general meeting for the issue of shares. Approval, if granted, will lapse at the earlier to occur of:

Subject to this approval, the provisions of the Statutes and our Constitution, the directors may allot and issue new shares to such persons on such terms and conditions and with the rights and privileges annexed thereto as such general meeting resolving upon the creation thereof shall direct and if no direction be given as the directors shall determine.

Only persons who are registered in our Register of Members are recognized under Singapore law as shareholders of our company with legal standing to institute shareholder actions against us or otherwise seek to enforce their rights as shareholders. We may close the Register of Members at any

time and for one or more periods, but the register may not be closed for an aggregate of more than thirty days in any calendar year.

Subject to applicable securities laws in relevant jurisdictions and our Constitution, our ordinary shares are freely transferable. The directors may in their absolute discretion decline to register any transfer of shares on which we have a lien and, in the case of shares not fully paid up, may refuse to register a transfer to a transferee of whom they do not approve, provided, however, that as required by the Singapore Companies Act the directors shall, within 30 days beginning with the day on which the application for a transfer of shares was made, serve a notice in writing to the applicant stating the facts which are considered to justify the refusal. Shares may be transferred by a duly signed instrument of transfer in the usual common form or in any other form which the directors may approve. The directors may decline to register any instrument of transfer unless, among other things, it is presented for registration together with a certificate of payment of stamp duty (if any), the share certificate(s) to which the transfer relates and such other evidence as they may reasonably require to show the right of the transferor to make the transfer. We will replace lost or destroyed certificates for shares upon notice to us and upon, among other things, the applicant furnishing evidence and indemnity as the directors may require and the payment of all applicable fees.

Under article 94 of our Constitution, at each annual general meeting, one-third of the directors, or, if their number is not a multiple of three, then the number nearest to but not more than one-third of the directors, are required to retire from office by rotation. Under article 95 of our Constitution, the directors required to retire in each year are those who have been in office longest since their last re-election or appointment. As between persons who became or were last re-elected directors on the same day, those required to retire are (unless they otherwise agree among themselves) determined by lot. Retiring directors are eligible for re-election. Under article 90 of our Constitution, any director holding office as a Chief Executive Officer (or an equivalent position) shall not, unless our board of directors determines otherwise, be subject to retirement by rotation or be taken into account in determining the number of directors to retire by rotation. Under article 100 of our Constitution, any director appointed by our board of directors either to fill a casual vacancy or as an additional director is eligible for re-election at the next annual general meeting, but shall not be taken into account in determining the number of directors required to retire by rotation at that annual general meeting.

We are required to hold an annual general meeting each year and not more than 15 months after the holding of the last preceding annual general meeting. Under our Constitution, any general meeting other than the annual general meeting is called an "extraordinary general meeting". The directors may convene an extraordinary general meeting whenever they think fit, and they must also do so upon the written request of shareholders representing not less than one-tenth of the paid-up shares as at the date of the deposit of the written request (disregarding paid-up shares held as treasury shares) carries the right of voting at general meetings. In addition, two or more shareholders holding not less than one-tenth of our total number of issued shares (excluding treasury shares) may call a meeting of our shareholders.

Unless otherwise required by law or by our Constitution, voting at general meetings is by ordinary resolution, requiring the affirmative vote of a simple majority of the total votes attached to all the fully paid-up shares which are represented at the meeting (of which at least fourteen days' written notice is given) and voting on such resolution in person or by proxy. An ordinary resolution suffices, for example, for appointments of directors. A special resolution, requiring an affirmative vote of a majority

of not less than three-fourths of the total votes attached to all the fully paid-up shares which are represented at the meeting (of which not less than 21 days' written notice specifying the intention to propose the resolution as a special resolution has been duly given) and voting on such resolution in person or by proxy, is necessary for certain matters under Singapore law, such as an alteration of our Constitution.

Voting at any meeting of shareholders is by a show of hands unless a poll is duly demanded before or on the declaration of the result of the show of hands. If voting is by a show of hands, every shareholder who is entitled to vote and who is present in person or by proxy or attorney or, in the case of a corporation, by a representative at the meeting has one vote. On a poll, every shareholder who is present in person or by proxy or by attorney or, in the case of a corporation, by a representative, has one vote for every share of which such shareholder holds or represents. A poll may be demanded by any of:

At a general meeting, our shareholders may declare dividends, but no dividend will be payable in excess of the amount recommended by the directors. The directors may also declare an interim dividend. No dividend may be paid except out of our profits. Except as otherwise may be provided in special rights as to dividends specified in the terms of issue of any shares (no such shares currently being in issue), all dividends are paid pro rata among the shareholders. To date, we have not declared any cash dividends on our ordinary shares and have no current plans to pay cash dividends in the foreseeable future.

In a general meeting, our shareholders may, upon the recommendation of the directors, by ordinary resolution:

The directors may also issue to shareholders rights to take up additional shares, in proportion to their shareholdings. These rights are subject to any conditions attached to the issue and the regulations of any stock exchange on which the ordinary shares are listed.

The acquisition of our ordinary shares is regulated by the SFA and the Singapore Code on Take-overs and Mergers.

such person is required to extend a mandatory take-over offer for the remaining voting shares of the company. The Securities Industry Council is empowered to waive compliance with this requirement. Subject to certain exceptions, a mandatory take-over offer made must be in cash or be accompanied by a cash alternative at not less than the highest price paid by the offeror or any party acting in concert with such person for voting rights of the offeree company during the offer period and within six months prior to its commencement.

On a winding-up or other return of capital, subject to any special rights attaching to any other class of shares, holders of ordinary shares will be entitled to participate in any surplus assets in proportion to their shareholdings.

As permitted by the laws of Singapore, our Constitution provides that, subject to the Statutes, our directors and officers will be indemnified by our company against all costs, charges, losses, expenses and liabilities incurred or to be incurred by him or her in the execution and discharge of his or her duties (including, without limitation, where he or she serves at the request of the registrant as a director, officer, employee or agent of another corporation, partnership, joint venture or other enterprise) or in relation thereto. Except as permitted under the Singapore Companies Act, directors and officers may not be indemnified by our company against any liability which by law would otherwise attach to them relating to any negligence, default, breach of duty or breach of trust of which they may be guilty in relation to our company.

There are no limitations imposed by the laws of Singapore or by our Constitution on the right of non-resident shareholders to hold or vote ordinary shares.

We are incorporated under the laws of Singapore. The following discussion summarizes material differences between the rights of holders of our ordinary shares and the rights of holders of the common stock of a typical corporation incorporated under the laws of the state of Delaware which result from differences in governing documents and the laws of Singapore and Delaware. For purposes of this section, we have summarized the Singapore Companies Act as in effect as of the date hereof.

This discussion does not purport to be a complete or comprehensive statement of the rights of holders of our ordinary shares under applicable law in Singapore and our Constitution or the rights of holders of the common stock of a typical corporation under applicable Delaware law and a typical certificate of incorporation and bylaws.

References to "Flex," "we," "us" and "our" in this "Comparison of Shareholder Rights" are only to Flex Ltd. and not to any of its subsidiaries.

Delaware		Singapore—Flex Ltd.

Board of Directors
A typical certificate of incorporation and bylaws would provide that the number of directors on the board of directors will be fixed from time to time by a vote of the majority of the authorized directors. Under Delaware law, a board of directors can be divided into classes and cumulative voting in the election of directors is only permitted if expressly authorized in a corporation's certificate of incorporation.		The constitution of companies will typically state the minimum and maximum number of directors as well as provide that the number of directors may be increased or reduced by shareholders via ordinary resolution passed at a general meeting, provided that the number of directors following such increase or reduction is within the maximum and minimum number of directors provided in our Constitution and the Singapore Companies Act, respectively. Our Constitution provides that the number of directors shall not be less than two nor, unless otherwise determined by our company in a general meeting, more than eleven. Under the Singapore Companies Act, the minimum number of directors shall be at least one director who is ordinarily resident in Singapore.

Singapore—Flex Ltd.

Limitation on Personal Liability of Directors

A typical certificate of incorporation provides for the elimination of personal monetary liability of directors for breach of fiduciary duties as directors to the fullest extent permissible under the laws of Delaware, except for liability (i) for any breach of a director's loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the Delaware General Corporation Law (relating to the liability of directors for unlawful payment of a dividend or an unlawful stock purchase or redemption) or (iv) for any transaction from which the director derived an improper personal benefit. A typical certificate of incorporation would also provide that if the Delaware General Corporation Law is amended so as to allow further elimination of, or limitations on, director liability, then the liability of directors will be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law as so amended.

Under the Singapore Companies Act, any provision that purports to exempt a director or officer of a company or by which a company directly or indirectly provides an indemnity for a director or officer of the company against any liability attaching to him or her in connection with any negligence, default, breach of duty or breach of trust in relation to the company continues to be void except that, in addition to purchasing and maintaining for any director and officer insurance against any liability attaching to such director or officer in connection with any negligence, default, breach of duty or breach of trust in relation to the company, a company may indemnify such director or officer against any liability incurred by the director or officer to a person other than the company, except when the indemnity is against:

•

any liability of the director or officer to pay (i) a fine in criminal proceedings, or (ii) a penalty sum payable to a regulatory authority for noncompliance with any requirement of a regulatory nature; or

•

any liability incurred by the director or officer (i) in defending criminal proceedings in which he or she is convicted, (ii) in defending civil proceedings brought by the company or a related company (i.e. the holding company, subsidiary or subsidiary of a common holding company) in which judgment is given against such director or officer; or (iii) in connection with an application under Section 76A(13) or Section 391 of the Singapore Companies Act in which the court refuses to grant him or her relief.

Interested Shareholders
Section 203 of the Delaware General Corporation Law generally prohibits a Delaware corporation from engaging in specified corporate transactions (such as mergers, stock and asset sales, and loans) with an "interested stockholder" for three years following the time that the stockholder becomes an interested stockholder. Subject to specified exceptions, an "interested stockholder" is a person or group that owns 15% or more of the corporation's outstanding voting stock (including any rights to acquire stock pursuant to an option, warrant, agreement, arrangement or understanding, or upon the exercise of conversion or exchange rights, and stock with respect to which the person has voting rights only), or is an affiliate or associate of the corporation and was the owner of 15% or more of the voting stock at any time within the previous three years. A Delaware corporation may elect to "opt out" of, and not be governed by, Section 203 through a provision in either its original certificate of incorporation, or an amendment to its original certificate or bylaws that was approved by majority stockholder vote.		There are no comparable provisions in Singapore with respect to public companies which are not listed on the Singapore Exchange Securities Trading Limited.
Removal of Directors
A typical certificate of incorporation and bylaws provide that, subject to the rights of holders of any preferred stock, directors may be removed at any time by the affirmative vote of the holders of at least a majority, or in some instances a supermajority, of the voting power of all of the then outstanding shares entitled to vote generally in the election of directors, voting together as a single class. A certificate of incorporation could also provide that such a right is only exercisable when a director is being removed for cause (removal of a director only for cause is the default rule in the case of a classified board).		According to the Singapore Companies Act, directors of a Singapore public company may be removed before expiration of their term of office with or without cause by ordinary resolution (i.e., a resolution which is passed by a simple majority of those shareholders present and voting in person or by proxy). Notice of the intention to move such a resolution has to be given to the company not less than 28 days before the meeting at which it is moved. Where any director removed in this manner was appointed to represent the interests of any particular class of shareholders or debenture holders, the resolution to remove such director will not take effect until such director's successor has been appointed.

Delaware		Singapore—Flex Ltd.

Filling Vacancies on the Board of Directors
A typical certificate of incorporation and bylaws provide that, subject to the rights of the holders of any preferred stock, any vacancy, whether arising through death, resignation, retirement, disqualification, removal, an increase in the number of directors or any other reason, may be filled by a majority vote of the remaining directors, even if such directors remaining in office constitute less than a quorum, or by the sole remaining director. Any newly elected director usually holds office for the remainder of the full term expiring at the annual meeting of stockholders at which the term of the class of directors to which the newly elected director has been elected expires.		The constitution of a Singapore public company typically provides that the directors have the power to appoint any person to be a director, either to fill a vacancy or as an addition to the existing directors, provided that the total number of directors will not at any time exceed the maximum number fixed in the constitution. Any newly elected director shall hold office until the next following annual general meeting, where such director will then be eligible for re-election. Our Constitution provides that the directors may appoint any person to be a director as an additional director or to fill a vacancy. Any person so appointed will only hold office until the next annual general meeting, and will then be eligible for re-election by ordinary resolution.
Amendment of Governing Documents
Amendment of Certification of Incorporation and Bylaws Under the Delaware General Corporation Law, amendments to a corporation's certificate of incorporation require the approval of stockholders holding a majority of the outstanding shares entitled to vote on the amendment. If a class vote on the amendment is required by the Delaware General Corporation Law, a majority of the outstanding stock of the class is required, unless a greater proportion is specified in the certificate of incorporation or by other provisions of the Delaware General Corporation Law. Under the Delaware General Corporation Law, the board of directors may amend bylaws if so authorized in the certificate of incorporation. The stockholders of a Delaware corporation also have the power to amend bylaws.		Alteration to Constitution Our Constitution may be altered by special resolution (i.e., a resolution passed by majority of not less than three-fourths of the shares entitled to vote, present in person or by proxy at a meeting). The board of directors has no right to amend the constitution.

Meetings of Shareholders
Annual and Special Meetings Typical bylaws provide that annual meetings of stockholders are to be held on a date and at a time fixed by the board of directors. Under the Delaware General Corporation Law, a special meeting of stockholders may be called by the board of directors or by any other person authorized to do so in the certificate of incorporation or the bylaws. Quorum Requirements Under the Delaware General Corporation Law, a corporation's certificate of incorporation or bylaws can specify the number of shares which constitute the quorum required to conduct business at a meeting, provided that in no event shall a quorum consist of less than one-third of the shares entitled to vote at a meeting.		Annual General Meetings All companies are required to hold an annual general meeting once every calendar year. The first annual general meeting must be held within 18 months of the company's incorporation and subsequently, not more than 15 months may elapse between annual general meetings. Extraordinary General Meetings Any general meeting other than the annual general meeting is called an "extraordinary general meeting". Two or more shareholders holding not less than 10% of the total number of issued shares (excluding treasury shares) may call an extraordinary general meeting. Notwithstanding anything in the constitution, the directors are required to convene a general meeting if required to do so by requisition (i.e., written notice to directors requiring that a meeting be called) by shareholder(s) holding not less than 10% of the paid-up shares of the company carrying voting rights. Our Constitution provides that the directors may, whenever they think fit, convene an extraordinary general meeting. Quorum Requirements Our Constitution provides that the quorum at any general meeting shall be holders holding in aggregate not less than 33¹/3% of the total number of issued and fully paid shares in the capital of our company for the time being, present in person or by proxy.

Indemnification of Officers, Directors and Employees
Under the Delaware General Corporation Law, subject to specified limitations in the case of derivative suits brought by a corporation's stockholders in its name, a corporation may indemnify any person who is made a party to any third-party action, suit or proceeding on account of being a director, officer, employee or agent of the corporation (or was serving at the request of the corporation in such capacity for another corporation, partnership, joint venture, trust or other enterprise) against expenses, including attorneys' fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by him or her in connection with the action, suit or proceeding through, among other things, a majority vote of a quorum consisting of directors who were not parties to the suit or proceeding, if the person:		As permitted by the laws of Singapore, our Constitution provides that, subject to the Statutes, our directors and officers will be indemnified by our company against all costs, charges, losses, expenses and liabilities incurred or to be incurred by him or her in the execution and discharge of his or her duties (including, without limitation, where he or she serves at the request of the registrant as a director, officer, employee or agent of another corporation, partnership, joint venture or other enterprise) or in relation thereto. Except as permitted under the Singapore Companies Act, directors and officers may not be indemnified by our company against any liability which by law would otherwise attach to them relating to any negligence, default, breach of duty or breach of trust of which they may be guilty in relation to our company.
• acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation or, in some circumstances, at least not opposed to its best interests; and • in a criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.
Delaware corporate law permits indemnification by a corporation under similar circumstances for expenses (including attorneys' fees) actually and reasonably incurred by such persons in connection with the defense or settlement of a derivative action or suit, except that no indemnification may be made in respect of any claim, issue or matter as to which the person is adjudged to be liable to the corporation unless the Delaware Court of Chancery or the court in which the action or suit was brought determines upon application that the person is fairly and reasonably entitled to indemnity for the expenses which the court deems to be proper.

Delaware		Singapore—Flex Ltd.

To the extent a director, officer, employee or agent is successful in the defense of such an action, suit or proceeding, the corporation is required by Delaware corporate law to indemnify such person for reasonable expenses incurred thereby. Expenses (including attorneys' fees) incurred by such persons in defending any action, suit or proceeding may be paid in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of that person to repay the amount if it is ultimately determined that that person is not entitled to be so indemnified.
Shareholder Approval of Business Combinations
Generally, under the Delaware General Corporation Law, completion of a merger, consolidation, or the sale, lease or exchange of substantially all of a corporation's assets or dissolution requires approval by the board of directors and by a majority (unless the certificate of incorporation requires a higher percentage) of outstanding stock of the corporation entitled to vote. The Delaware General Corporation Law also requires a special vote of stockholders in connection with a business combination with an "interested stockholder" as defined in section 203 of the Delaware General Corporation Law. See "—Interested Shareholders" above.		The Singapore Companies Act mandates that specified corporate actions require approval by the shareholders in a general meeting, notably: • notwithstanding anything in the company's constitution, directors are not permitted to carry into effect any proposals for disposing of the whole or substantially the whole of the company's undertaking or property unless those proposals have been approved by shareholders in a general meeting; • subject to the constitution of each amalgamating company, an amalgamation proposal must be approved by the shareholders of each amalgamating company via special resolution at a general meeting; and • notwithstanding anything in the company's constitution, the directors may not, without the prior approval of shareholders, issue shares, including shares being issued in connection with corporate actions.
Shareholder Action Without a Meeting
Under the Delaware General Corporation Law, unless otherwise provided in a corporation's certificate of incorporation, any action that may be taken at a meeting of stockholders may be taken without a meeting, without prior notice and without a vote if the holders of outstanding stock, having not less than the minimum number of votes that would be necessary to authorize such action, consent in writing. It is not uncommon for a corporation's certificate of incorporation to prohibit such action.		There are no equivalent provisions in respect of public companies which are not listed in Singapore. As a result, shareholder action by written consent is not permitted.

Delaware		Singapore—Flex Ltd.

Shareholder Suits
Under the Delaware General Corporation Law, a stockholder may bring a derivative action on behalf of the corporation to enforce the rights of the corporation. An individual also may commence a class action suit on behalf of himself or herself and other similarly situated stockholders where the requirements for maintaining a class action under the Delaware General Corporation Law have been met. A person may institute and maintain such a suit only if such person was a stockholder at the time of the transaction which is the subject of the suit or his or her shares thereafter devolved upon him or her by operation of law. Additionally, under Delaware case law, the plaintiff generally must be a stockholder not only at the time of the transaction which is the subject of the suit, but also through the duration of the derivative suit. The Delaware General Corporation Law also requires that the derivative plaintiff make a demand on the directors of the corporation to assert the corporate claim before the suit may be prosecuted by the derivative plaintiff, unless such demand would be futile.		Standing Only registered shareholders of our company reflected in our shareholder register are recognized under Singapore law as shareholders of our company. As a result, only registered shareholders have legal standing to institute shareholder actions against us or otherwise seek to enforce their rights as shareholders. Holders of book-entry interests in our shares will be required to exchange their book-entry interests for certificated shares and to be registered as shareholders in our shareholder register in order to institute or enforce any legal proceedings or claims against us, our directors or our executive officers relating to shareholder rights. A holder of book-entry interests may become a registered shareholder of our company by exchanging its interest in our shares for certificated shares and being registered in our shareholder register. Derivative Actions The Singapore Companies Act has a provision which provides a mechanism enabling shareholders to apply to the court for leave to bring a derivative action on behalf of the company. Derivative actions are also allowed as a common law action. Applications are generally made by shareholders of the company or individual directors, but courts are given the discretion to allow such persons as they deem proper to apply (e.g., beneficial owner of shares) in the appropriate circumstances.
		It should be noted that this provision of the Singapore Companies Act is primarily used by minority shareholders to bring an action in the name and on behalf of the company or intervene in an action to which the company is a party for the purpose of prosecuting, defending or discontinuing the action on behalf of the company. Prior to commencing a derivative action, the court will need to be satisfied that, the applicant has given 14 days' notice to the directors of the company of its intention to apply to the court for leave to bring an action or arbitration if the directors of the company do not bring, diligently prosecute or defend or discontinue the

Delaware		Singapore—Flex Ltd.

		action or arbitration, the applicant is acting in good faith, and it appears to be prima facie in the interests of the company that the action or arbitration be brought, prosecuted, defended or discontinued. Class Actions The concept of class action suits, which allows individual shareholders to bring an action seeking to represent the class or classes of shareholders, does not exist in Singapore. However, it is possible as a matter of procedure for a number of shareholders to lead an action and establish liability on behalf of themselves and other shareholders who join in or who are made parties to the action. These shareholders are commonly known as "lead plaintiffs."
Distributions and Dividends; Repurchases and Redemptions
The Delaware General Corporation Law permits a corporation to declare and pay dividends out of statutory surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and/or for the preceding fiscal year as long as the amount of capital of the corporation following the declaration and payment of the dividend is not less than the aggregate amount of the capital represented by the issued and outstanding stock of all classes having a preference upon the distribution of assets. Under the Delaware General Corporation Law, any corporation may purchase or redeem its own shares, except that generally it may not purchase or redeem these shares if the capital of the corporation is impaired at the time or would become impaired as a result of the redemption. A corporation may, however, purchase or redeem out of capital shares that are entitled upon any distribution of its assets to a preference over another class or series of its shares if the shares are to be retired and the capital reduced.		The Singapore Companies Act provides that no dividends can be paid to shareholders except out of profits. The Singapore Companies Act does not provide a definition on when profits are deemed to be available for the purpose of paying dividends and this is accordingly governed by case law. Our Constitution provides that no dividend shall be payable except out of the profits of our company, or in excess of the amount recommended by our directors. Acquisition of a Company's Own Shares The Singapore Companies Act generally prohibits a company from acquiring its own shares subject to certain exceptions. Any contract or transaction by which a company acquires or transfers its own shares in contravention of the said prohibition is void. However, provided that it is expressly permitted to do so by its constitution and subject to the special conditions of each permitted acquisition contained in the Singapore Companies Act, a company may: • make an off-market purchase of its own shares in accordance with an equal access scheme authorized in advance at a general meeting;

Delaware

Singapore—Flex Ltd.

•

make a selective off-market purchase of its own shares in accordance with an agreement authorized in advance at a general meeting by a special resolution where persons whose shares are to be acquired and their associated persons have abstained from voting; and

•

make an acquisition of its own shares under a contingent purchase contract which has been authorized in advance at a general meeting by a special resolution,

provided that the total number of ordinary shares that may be acquired by a company in a relevant period may not exceed 20% of the total number of ordinary shares in that class as of the date of the resolution to acquire the shares, whichever is higher. Where, however, a company has reduced its share capital by a special resolution or a Singapore court made an order to such effect, the total number of ordinary shares in any class shall be taken to be the total number of ordinary shares in that class as altered by the special resolution or the order of the court. Payment must be made out of the company's distributable profits or capital, provided that the company is solvent.

A company may also purchase its own shares by an order of a Singapore court.

Our Constitution provides that subject to the Singapore Companies Act, our company may purchase or otherwise acquire its issued shares on such terms and in such manner as our company may from time to time think fit. If required by the Singapore Companies Act, any share that is so purchased or acquired by our company shall, unless held in treasury in accordance with the Singapore Companies Act, be deemed to be cancelled immediately on purchase or acquisition by our company.

Delaware		Singapore—Flex Ltd.

		Redemption of preference shares A company may redeem redeemable preference shares, provided that preference shares shall not be redeemed out of capital unless all the directors make a solvency statement in relation to such redemption in accordance with the Singapore Companies Act. In addition, certain filings are also required to be made to the Registrar of Companies in connection with such redemption of redeemable preference shares.
		Financial Assistance for the Acquisition of Shares A public company may not give financial assistance to any person whether directly or indirectly for the purpose of: • the acquisition or proposed acquisition of shares in the company or units of such shares; or • the acquisition or proposed acquisition of shares in its holding company or ultimate holding company or units of such shares,
		subject to certain exceptions. Financial assistance may take the form of a loan, the giving of a guarantee, the provision of security, the release of an obligation, the release of a debt or otherwise. However, it should be noted that a company may provide financial assistance for the acquisition of its shares or shares in its holding company or ultimate holding company if (i) the giving of the financial assistance does not materially prejudice the interests of the company or its shareholders or the company's ability to pay its creditors, and the board of directors approves the giving of the financial assistance in accordance with the provisions of the Singapore Companies Act; or (ii) it complies with the requirements (including but not limited to approval of the shareholders by special resolution) set out in the Singapore Companies Act. Our Constitution provides that, except as is otherwise expressly permitted by the Singapore Companies Act, our company shall not give any financial assistance for the purpose of, or in connection with, the acquisition or proposed acquisition of shares or units of shares in our company or our holding company.

Delaware		Singapore—Flex Ltd.

Transactions with Officers or Directors
Under the Delaware General Corporation Law, some contracts or transactions in which one or more of a corporation's directors has an interest are not void or voidable because of such interest provided that some conditions, such as obtaining the required approval and fulfilling the requirements of good faith and full disclosure, are met. Under the Delaware General Corporation Law, either (a) the stockholders or the board of directors must approve in good faith any such contract or transaction after full disclosure of the material facts or (b) the contract or transaction must have been "fair" as to the corporation at the time it was approved. If board approval is sought, the contract or transaction must be approved in good faith by a majority of disinterested directors after full disclosure of material facts, even though less than a majority of a quorum.		Under the Singapore Companies Act, directors and chief executive officer are not prohibited from dealing with the company, but where they have an interest in a transaction with the company, that interest must be disclosed to the board of directors. In particular, every director and chief executive officer who is in any way, whether directly or indirectly, interested in a transaction or proposed transaction with the company must, as soon practicable after the relevant facts have come to such director's or chief executive officer's knowledge, declare the nature of such director's or chief executive officer's interest at a board of directors' meeting or by sending a written notice to the company containing details on the nature, character and extent of his interest in the transaction or proposed transaction with the company.
		There is however no requirement for disclosure where the interest of the director or chief executive officer consists only of being a member or creditor of a corporation which is interested in the transaction or proposed transaction with the company if the interest may properly be regarded as immaterial. Where the transaction or proposed transaction relates to any loan to the company, a director or chief executive officer shall not be deemed to be interested in the transaction or proposed transaction by reason only that the director or chief executive officer, as applicable, has guaranteed the repayment of such loan, unless the constitution provides otherwise. Every director and chief executive officer who holds any office or possesses any property which directly or indirectly might create duty or interests in conflict with their duties or interests as director or chief executive officer, as applicable, is required to declare at a meeting of directors the fact and the nature, character and extent of the conflict or send a written notice to the company setting out the fact and the nature, character and extent of the conflict.

Delaware		Singapore—Flex Ltd.

		The Singapore Companies Act extends the scope of this statutory duty of a director and chief executive officer to disclose any interests by pronouncing that an interest of a member of a director's or chief executive officer's family (including spouse, son, adopted son, step-son, daughter, adopted daughter and step-daughter) will be treated as an interest of the director or chief executive officer, as applicable. Further, where the transaction or proposed transaction is to be made with or for the benefit of a related company, a director or chief executive officer shall not be deemed to be interested in the transaction or proposed transaction by reason only that such director or chief executive officer, as applicable, is also a director or chief executive officer, as applicable, of that company, unless the constitution provides otherwise. Subject to specified exceptions, the Singapore Companies Act prohibits a Singapore company from making a loan or quasi-loan to its directors or to directors of a related corporation, or giving a guarantee or security in connection with such a loan or quasi-loan. Companies are also prohibited from making loans to its directors' spouse or children (whether adopted or natural or step-children), or giving a guarantee or security in connection with such a loan or entering into a credit transaction by the company as creditor for the benefit of any director or director of a related corporation.
Dissenters' Rights
Under the Delaware General Corporation Law, a stockholder of a corporation participating in some types of major corporate transactions may, under varying circumstances, be entitled to appraisal rights pursuant to which the stockholder may receive cash in the amount of the fair market value of his or her shares in lieu of the consideration he or she would otherwise receive in the transaction.		There are no equivalent provisions in Singapore under the Singapore Companies Act.

Delaware		Singapore—Flex Ltd.

Cumulative Voting
Under the Delaware General Corporation Law, a corporation may adopt in its bylaws that its directors shall be elected by cumulative voting. When directors are elected by cumulative voting, a stockholder has the number of votes equal to the number of shares held by such stockholder times the number of directors nominated for election. The stockholder may cast all of such votes for one director or among the directors in any proportion.		There is no equivalent provision in respect of companies incorporated in Singapore.
Anti-Takeover Measures
Under the Delaware General Corporation Law, the certificate of incorporation of a corporation may give the board the right to issue new classes of preferred stock with voting, conversion, dividend distribution, and other rights to be determined by the board at the time of issuance, which could prevent a takeover attempt and thereby preclude shareholders from realizing a potential premium over the market value of their shares. In addition, Delaware law does not prohibit a corporation from adopting a stockholder rights plan, or "poison pill," which could prevent a takeover attempt and also preclude shareholders from realizing a potential premium over the market value of their shares.		The constitution of a Singapore public company typically provides that the company may allot and issue new shares of a different class with preferential, deferred, qualified or other special rights as its board of directors may determine with the prior approval of the company's shareholders in a general meeting. Our Constitution provides that, subject to the Singapore Companies Act and our Constitution, no shares may be issued by our directors without the prior approval of our company in a general meeting but subject thereto and to the provisions of our Constitution, our directors may allot and issue shares or grant options over or otherwise dispose of the same to such persons on such terms and conditions and for such consideration (if any) and at such time as our company in a general meeting may approve. Singapore law does not generally prohibit a corporation from adopting "poison pill" arrangements which could prevent a takeover attempt and also preclude shareholders from realizing a potential premium over the market value of their shares. However, under the Singapore Code on Take-overs and Mergers, if, in the course of an offer, or even before the date of the announcement of the offer, the board of the offeree company has reason to believe that a bona fide offer is imminent, the board must not, except pursuant to a contract entered into earlier, take any action, without the approval of shareholders at a general meeting, on the affairs of the offeree company that could effectively result in any bona fide offer being frustrated or the shareholders being denied an opportunity to decide on its merits. Such actions include but are not limited to the issue of shares.
		See "Description of Ordinary Shares—Takeovers" in this prospectus for a description of the Singapore Code on Take-overs and Mergers.

Flex Ltd. may issue debt securities at any time and from time to time, in one or more series, under an indenture between Flex Ltd. and U.S. Bank National Association, as trustee. Any debt securities that Flex Ltd. may issue may be senior or subordinated debt of Flex Ltd. and may be convertible into and/or exchangeable for ordinary shares or may be non-convertible. We will describe the specific terms of each series of debt securities we offer in a supplement to this prospectus. If any specific terms of the debt securities described in a prospectus supplement differ from any of the terms described in this prospectus, then the terms described in the applicable prospectus supplement will supersede the terms described in this prospectus. The terms of the debt securities will include those set forth in the indenture and the applicable supplemental indenture, if any, and those made a part of the indenture or any applicable supplemental indenture by the Trust Indenture Act of 1939, as amended. You should read the applicable prospectus supplement and the provisions of the indenture and the applicable supplemental indenture, if any, in their entirety before investing in the debt securities.

We and/or the selling securityholders, if applicable, may sell the securities in one or more of the following ways (or in any combination) from time to time:

The prospectus supplement will state the terms of the offering of the securities, including:

Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If we and/or the selling securityholders, if applicable, use underwriters in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

We and/or the selling securityholders, if applicable, may sell the securities through agents from time to time. The prospectus supplement will name any agent involved in the offer or sale of the securities and any commissions we pay to them. Generally, any agent will be acting on a best-efforts basis for the period of its appointment.

We and/or the selling securityholders, if applicable, may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and

delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Underwriters and agents may be entitled under agreements entered into with us and/or the selling securityholders, if applicable, to indemnification by us against certain civil liabilities, including liabilities under the Securities Act or to contribution with respect to payments which the underwriters or agents may be required to make. Underwriters and agents may be customers of, engage in transactions with, or perform services for us and its affiliates in the ordinary course of business.

Each series of securities issued pursuant to this prospectus other than our ordinary shares, which are listed on The Nasdaq Global Select Market, will be a new issue of securities and will have no established trading market. Any underwriters to whom securities are sold for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. The securities, other than our ordinary shares, may or may not be listed on a national securities exchange.

In order to facilitate the offering of the securities, any underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the securities or any other securities the prices of which may be used to determine payments on such securities. Specifically, any underwriters may overallot in connection with the offering, creating a short position for their own accounts. In addition, to cover overallotments or to stabilize the price of the securities or of any such other securities, the underwriters may bid for, and purchase, the securities or any such other securities in the open market. Finally, in any offering of the securities through a syndicate of underwriters, the underwriting syndicate may reclaim selling concessions allowed to an underwriter or a dealer for distributing the securities in the offering if the syndicate repurchases previously distributed securities in transactions to cover syndicate short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the securities above independent market levels. Any such underwriters are not required to engage in these activities and may end any of these activities at any time.

Information about selling securityholders, if any, will be set forth in a prospectus supplement, in an amendment to the registration statement of which this prospectus is a part or in filings we make with the SEC under the Exchange Act that are incorporated by reference.

Certain legal matters relating to the issuance and sale of the securities with respect to Singapore law will be passed upon for us by Allen & Gledhill LLP. Certain legal matters relating to the issuance and sale of the securities with respect to U.S. law will be passed upon for us by Curtis, Mallet-Prevost, Colt & Mosle LLP, New York, New York. Certain legal matters with respect to the validity of the securities offered pursuant to this prospectus and any prospectus supplement will be passed upon for any underwriters or agents by counsel named in the applicable prospectus supplement.

The consolidated financial statements as of March 31, 2017 and 2016, and for each of the three years in the period ended March 31, 2017, incorporated in this prospectus by reference from the Company's Annual Report on Form 10-K for the year ended March 31, 2017, and the effectiveness of the Company's internal control over financial reporting have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports, which are incorporated by reference herein. Such consolidated financial statements have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.

With respect to the unaudited interim financial information for the periods ended June 30, 2017 and July 1, 2016, September 29, 2017 and September 30, 2016 and December 31, 2017 and December 31, 2016, which is incorporated herein by reference, Deloitte & Touche LLP, an independent registered public accounting firm, have applied limited procedures in accordance with the standards of the Public Company Accounting Oversight Board (United States) for a review of such information. However, as stated in their reports included in the Company's Quarterly Report on Form 10-Q for the quarterly periods ended June 30, 2017, September 29, 2017 and December 31, 2017 and incorporated by reference herein, they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Deloitte & Touche LLP are not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their reports on the unaudited interim financial information because those reports are not "reports" or a "part" of the registration statement prepared or certified by an accountant within the meaning of Sections 7 and 11 of the Securities Act.
