PROSPECTUS SUPPLEMENT (Subject to Completion)

Dated January 29, 2024

7,625,000 Shares

TD SYNNEX Corporation

Common Stock

This prospectus supplement relates to the resale of up to an aggregate of 7,625,000 shares of common stock of TD SYNNEX Corporation, a Delaware corporation, by certain entities managed by affiliates of Apollo Global Management, Inc. (the “Selling Stockholders”). Pursuant to Rule 429 under the Securities Act of 1933, as amended, the prospectus dated October 10, 2023, as supplemented by this prospectus supplement, is a combined prospectus relating to (a) up to 35,199,549 shares of our common stock previously registered for resale by the Selling Stockholders pursuant to the registration statement on Form S-3 filed on September 2, 2021 (File No. 333-259270) and (b) up to 9,762,063 shares of our common stock registered for resale by other selling stockholders pursuant to the registration statement on Form S-3 filed on October 10, 2023 (File No. 333-274915). We are not selling any shares of our common stock under this prospectus and we will not receive any of the proceeds from the sale of shares by the Selling Stockholders. Our common stock is listed on The New York Stock Exchange (the “NYSE”) under the symbol “SNX.” On January 26, 2024, the last reported sale price for our common stock on the NYSE was $105.28 per share.

We intend to purchase from the underwriters 1,375,000 shares of our common stock offered in this offering, at a price per share equal to the price per share to be paid by the underwriters to the Selling Stockholders, as part of our existing stock repurchase program, so long as the total amount of shares we purchase from the underwriters do not exceed $160.0 million (the “Concurrent Share Repurchase”). Assuming a repurchase price of $105.28 per share, the last reported sale price per share of our common stock on the NYSE on January 26, 2024, we would purchase 1,375,000 shares of our common stock from the underwriters in the Concurrent Share Repurchase. See “Concurrent Share Repurchase,” beginning on page S-9 of this prospectus supplement.

Our business and an investment in our common stock involve significant risks. These risks are described under the caption “Risk Factors” beginning on page S-6 of this prospectus supplement, as well as those contained in the accompanying prospectus and in the documents incorporated by reference herein.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

The underwriters may exercise their option to purchase up to an additional 1,143,750 shares from the Selling Stockholders at the price set forth above for 30 days after the date of this prospectus supplement. References to “underwriters” in this prospectus supplement refer to the underwriters named in the “Underwriting (Conflict of Interest)” section of this prospectus supplement.

The underwriters expect to deliver the shares against payment in New York, New York on or approximately     , 2024.

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS SUPPLEMENT

This document is part of a registration statement that was filed with the Securities and Exchange Commission, or the SEC, using a “shelf” registration process and consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this offering and also supplements and updates information contained in the accompanying prospectus and the documents incorporated by reference into this prospectus supplement and the accompanying prospectus. The second part is the accompanying prospectus, which provides more general information, some of which may not apply to this offering. This prospectus supplement may add, update, or change information contained in the accompanying prospectus. Generally, when we refer to this prospectus, we are referring to both parts of this document combined.

RISK FACTORS

Investing in our common stock involves a high degree of risk. Before making an investment decision, you should carefully consider the risks described below and in our most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, as well as any amendments thereto reflected in subsequent filings, each of which are incorporated by reference in this prospectus supplement and the accompanying prospectus, and all of the other information in this prospectus supplement and the accompanying prospectus, including our financial statements and related notes incorporated by reference in this prospectus supplement and the accompanying prospectus. If any of these risks is realized, our business, financial condition, results of operations and prospects could be materially and adversely affected. In that event, the trading price of our common stock could decline, and you could lose part or all of your investment. Additional risks and uncertainties that are not yet identified or that we think are immaterial may also materially harm our business, operating results and financial condition and could result in a complete loss of your investment.

Sales or the availability for sale of a substantial number of shares of our common stock in the public market could cause our stock price to be volatile or fall.

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could abruptly depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. As of January 17, 2024, we had approximately 89,094,097 shares of our common stock outstanding, 26,153,049 of which is held by the Selling Stockholders. We, the Selling Stockholders and all of our executive officers and directors have agreed that, for a period of 30 days after the date of this prospectus, we and they will not, without the prior written consent of Goldman Sachs & Co. LLC, dispose of any shares of our common stock or any securities convertible into or exchangeable for our common stock, subject to certain exceptions and excluding any shares to be sold in this offering. See “Underwriting (Conflict of Interest).” Following the expiration of the applicable lock-up period, all of the issued and outstanding shares of our common stock will be eligible for future sale, subject to applicable volume, manner of sale, holding periods, and other limitations of Rule 144. The underwriters may, in their sole discretion, release all or any portion of the shares subject to lock-up agreements at any time and for any reason. In addition, the Selling Stockholders have certain registration rights that require us to register the sale of common stock held by them, including in connection with underwritten offerings.

The availability for sale of a large number of shares of our common stock in the public market upon expiration of the lock-up agreements, or the early release of any lock-up agreements, could increase the potential for stock price volatility or cause the price of our common stock to decline. Even if we put strategies in place to attempt to address potential or actual volatility, the effectiveness of such strategies is uncertain.

In addition, certain of the Selling Stockholders have pledged a significant number of the shares of common stock held by them pursuant to margin loan agreements, and any foreclosure upon those shares could result in sales of a substantial number of shares of our common stock in the public market, which could substantially decrease the market price of our common stock.

Our bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our bylaws provide that the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) is the exclusive forum for (i) any derivative action or proceeding brought on behalf of the corporation, (ii) any action asserting a claim of breach of fiduciary duty owed by any current or former director, officer, other employee or agent of the corporation to the corporation or the corporation’s stockholders, including a claim alleging the aiding and abetting of such a breach of fiduciary duty, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General

S-6

Corporation Law or the bylaws or the certificate of incorporation or (iv) any action asserting a claim governed by the internal affairs doctrine or asserting an “internal corporate claim”. This choice of forum provision may limit a stockholder’s ability to bring a claim in a different judicial forum that such stockholder views as more favorable for such disputes which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provisions contained in our bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

CAUTIONARY NOTE CONCERNING FORWARD-LOOKING STATEMENTS

Forward-looking statements included in this prospectus or information and other documents incorporated by reference herein are based on various facts and derived utilizing numerous important assumptions and are subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Forward-looking statements include the information concerning our future financial performance, business strategy, projected plans and objectives, as well as projections of macroeconomic and industry trends, which are inherently unreliable due to the multiple factors that impact economic trends, and any such variations may be material. Statements preceded by, followed by or that otherwise include terms such as “believes,” “expects,” “anticipates,” “intends,” “projects,” “estimates,” “plans,” and similar or the negative of such expressions or future or conditional verbs such as “will,” “should,” “would,” “may” and “could” are generally forward looking in nature and not historical facts. You should not place undue reliance on these forward-looking statements. We discuss in greater detail in, and in the documents incorporated by reference into, this prospectus supplement and the accompanying prospectus, many of these risks, uncertainties, and assumptions, including under the heading “Risk Factors.” Additional cautionary statements or discussions of risks, uncertainties and assumptions that could cause our actual results to differ materially from those described in the forward-looking statements include, but are not limited to, those discussed in the section entitled “Risk Factors” beginning on page 4 of the prospectus, and under Part I, Item 1A, Risk Factors, of our Annual Report on Form 10-K for the period ended November 30, 2023 incorporated by reference in this prospectus.

Any forward-looking statement made by us in this prospectus supplement, the accompanying prospectus, or any of the documents incorporated by reference in this prospectus supplement and the accompanying prospectus speaks only as of the date on which it was made. Except as required by law, we expressly disclaim any obligation or undertaking to release publicly any updates or revisions to any forward- looking statements contained herein to reflect any change in our expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based. You should, however, review additional disclosures we make in our Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K filed with the SEC.

You should read this prospectus supplement, the accompanying prospectus, and the documents that we incorporated by reference in this prospectus supplement and the accompanying prospectus completely and with the understanding that our actual future results, levels of activity and performance as well as other events and circumstances may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

CONCURRENT SHARE REPURCHASE

We intend to purchase from the underwriters 1,375,000 shares of our common stock offered in this offering, at a price per share equal to the price per share to be paid by the underwriters, to the Selling Stockholders as part of our existing stock repurchase program, so long as the total amount of shares we purchase from the underwriters does not exceed $160.0 million. Assuming a repurchase price of $105.28 per share, the last reported sale price per share of our common stock on the NYSE on January 26, 2024, we would purchase 1,375,000 shares of our common stock from the underwriters in the Concurrent Share Repurchase. The terms and conditions of the Concurrent Share Repurchase were reviewed and approved by the audit committee of our board of directors, comprised of independent and disinterested directors. The Concurrent Share Repurchase will be made under our existing share repurchase program authorized by our board of directors in January 2023 and will reduce the remaining amount available for purchase. The Concurrent Share Repurchase will be funded from our existing cash on hand. The underwriters will not receive any compensation for the shares being repurchased by us.

S-9

USE OF PROCEEDS

All of the shares of common stock being offered hereby are being sold by the Selling Stockholders identified in this prospectus supplement. We will not receive any proceeds from the sale of the shares of common stock by the Selling Stockholders. The Selling Stockholders will receive all of the net proceeds from this offering. We have agreed to pay all expenses relating to registering the shares of common stock. See “Selling Stockholders.”

S-10

SELLING STOCKHOLDERS

The following table sets forth information regarding the beneficial ownership of our shares of common stock as of January 26, 2024, before and after giving effect to this offering by the Selling Stockholders (including the Concurrent Share Repurchase).

The amounts and percentages of shares beneficially owned are reported on the basis of rules and regulations of the SEC governing the determination of beneficial ownership of securities. Under rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest. The address for the beneficial owner is set forth in the footnote to the table.

Percentage computations are based on 89,340,655 shares of our common stock outstanding as of November 30, 2023 before giving effect to the Concurrent Share Repurchase, and 87,965,655 shares of our common stock outstanding after giving effect to the repurchase of 1,375,000 shares in the Concurrent Share Repurchase (assuming a repurchase price of $105.28 per share, the last reported sale price per share of our common stock on the NYSE on January 26, 2024).

S-11

Material Relationships with Selling Stockholders

Apollo

Apollo Global Management, Inc. (“Apollo” and, together with its affiliates (including the Selling Stockholders), the “Apollo Entities”) is an affiliate of the Company. Without giving effect to this offering or to the Concurrent Share Repurchase, as of November 30, 2023, the Apollo Entities beneficially owned approximately 29.3% of outstanding shares of our common stock, and, after giving effect to this offering and the Concurrent Share Repurchase, the Apollo Entities will beneficially own approximately 21.1% of outstanding shares of our common stock (or approximately 19.8% of outstanding shares of our common stock if the underwriters’ option to purchase additional shares is exercised in full).

The Apollo Entities acquired these shares from us in connection with our acquisition of Tiger Parent, the indirect parent entity of Tech Data. Such shares of common stock were sold and issued by us to the Apollo Entities pursuant to the terms and subject to the conditions of the Merger Agreement. Additionally, in connection with the completion of the Mergers, we entered into an Investor Rights Agreement (the “Investor Rights Agreement”) with Tiger Parent Holdings, L.P., an affiliate of Apollo. Pursuant to the Investor Rights Agreement, the Apollo Entities have the right to nominate (i) up to four directors if the Apollo Entities own 30% or more of the outstanding shares of our common stock, (ii) up to three directors if the Apollo Entities own between 20% and 30% of the outstanding shares of our common stock, (iii) up to two directors, if the Apollo Entities own between 10% and 20% of the outstanding shares of our common stock or (iv) up to one director, if the Apollo Entities own between 5% and 10% of the outstanding shares of our common stock (such directors nominated by the Apollo Entities, the “Apollo Directors”). The current Apollo Directors are Robert Kalsow-Ramos, Nayaki Nayyar, Matthew Nord, and Merline Saintil. The Investor Rights Agreement also provides that, of the remaining directors who are not Apollo Directors, one director shall be the then-serving Chief Executive Officer of the Company, currently Richard Hume, and the other directors will be nominated in accordance with the provisions of our bylaws and Certificate of Incorporation. The Apollo Directors must fulfill their pro rata portion of any diversity requirements pursuant to law, stock exchange rules, or other regulatory requirements based on the percentage of our board of directors consisting of Apollo Directors.

Under the Investor Rights Agreement, we have waived the corporate opportunity doctrine to the extent permitted under the Delaware General Corporation Law with respect to the Apollo Directors and Apollo Entities, so long as such person is not an employee of the Company or our subsidiaries (the “Covered Persons”). Specifically, we agreed that the Covered Persons do not have a duty to refrain from: (i) investing in or conducting any business of any kind, (ii) doing business with our or any of our affiliates’ clients, customers, vendors or lessors, or (iii) making any investments in any kind of property in which we may make investments. Further, we agreed, among other things, subject to any express agreement otherwise that may from time to time be in effect, that if a Covered Person acquires knowledge of a potential transaction which may constitute a corporate opportunity for both (a) the Covered Person outside of his or her capacity as a member of our board of directors and (b) the Company, then the Covered Person shall not have any duty to offer or communicate information regarding such corporate opportunity to us, and we renounced any interest or expectancy in any potential transaction or matter of

S-12

which the Covered Person acquires knowledge, except for any corporate opportunity which is expressly offered to a Covered Person in writing solely in his or her capacity as a member of our board of directors, or as expressly agreed otherwise.

In addition, we granted the Apollo Entities certain registration rights pursuant to the Investor Rights Agreement. Subject to several exceptions, including our right to defer a demand registration, underwritten shelf registration or non-underwritten shelf registration under certain circumstances, the Apollo Entities have the right to require us to register the sale of the shares of common stock held by them on Form S-3, subject to offering size and other restrictions. The Apollo Entities also have the right to request marketed and non-marketed underwritten offerings using a shelf registration statement.

If we propose to file certain types of registration statements under the Securities Act with respect to an offering of shares of common stock (including for sale by us or at the request of any holder of registration rights), then we will be required to offer the Apollo Entities the opportunity to register any number of shares of common stock that they request, on the terms and conditions set forth in the Investor Rights Agreement (customarily known as “piggyback rights”).

The registration rights granted under the Investor Rights Agreement are subject to customary restrictions including, if a registration is underwritten, any limitations on the number of shares to be included in the underwritten offering as reasonably advised by the managing underwriters.

All expenses of registration under the Investor Rights Agreement, including the legal fees of counsel chosen by the Apollo Entities, but excluding all applicable underwriting fees, discounts and similar charges, will be paid by us.

Any sales in the public market of any shares of common stock registrable pursuant to the registration rights granted under the Investor Rights Agreement could depress the market price of our shares of common stock. See “Risk Factors—Sales or the availability for sale of a substantial number of shares of our common stock in the public market could cause our stock price to be volatile or fall.”

The Investor Rights Agreement also contains customary indemnification and contribution provisions.

This offering is being made pursuant to the registration rights granted under the Investor Rights Agreement. Our director Robert Kalsow-Ramos is a Partner, Private Equity at Apollo and our director Matthew Nord is a Partner and Co-Head of Private Equity at Apollo.

For more information on these relationships, please refer to the 2023 Annual Report, which is incorporated herein by reference.

We intend to purchase from the underwriters 1,375,000 shares of our common stock offered in this offering, at a price per share equal to the price per share to be paid by the underwriters to the Selling Stockholders, as part of our existing stock repurchase program, so long as the total amount of shares we purchase from the underwriters does not exceed $160.0 million. Assuming a repurchase price of $105.28 per share, the last reported sale price per share of our common stock on the NYSE on January 26, 2024, we would purchase 1,375,000 shares of our common stock from the underwriters in the Concurrent Share Repurchase. See “Concurrent Share Repurchase.”

S-13

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES TO NON-U.S. HOLDERS

The following is a general discussion of the material U.S. federal income tax considerations applicable to non-U.S. holders (as defined herein) with respect to their ownership and disposition of shares of our common stock sold pursuant to this offering. This discussion does not address all aspects of U.S. federal income tax considerations relating thereto. This discussion also does not address the tax considerations arising under the laws of any non-U.S., state, or local jurisdiction, nor under U.S. federal gift and estate tax laws, except to the limited extent provided below. For the purposes of this discussion, a non-U.S. holder means a beneficial owner of our common stock (other than a partnership or an entity or arrangement treated as a partnership for U.S. federal income tax purposes) that is not, for U.S. federal income tax purposes:

This discussion is based on current provisions of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), existing U.S. Treasury Regulations promulgated thereunder, published administrative pronouncements and rulings of the U.S. Internal Revenue Service (“IRS”), and judicial decisions, all as in effect as of the date of this prospectus supplement. These authorities are subject to change and to differing interpretation, possibly with retroactive effect. Any change or differing interpretation could alter the tax consequences to non-U.S. holders described in this prospectus supplement and the accompanying prospectus.

We assume in this discussion that a non-U.S. holder holds shares of our common stock as a capital asset within the meaning of Section 1221 of the Code (generally, for investment). This discussion does not address all aspects of U.S. federal income taxation that may be relevant to a particular non-U.S. holder in light of that non-U.S. holder’s individual circumstances, nor does it address any estate or gift tax consequences, except to the limited extent provided below, or any aspects of U.S. state, local or non-U.S. taxes. This discussion also does not consider any specific facts or circumstances that may apply to a non-U.S. holder and does not address the special tax rules applicable to particular non-U.S. holders, such as holders that own, or are deemed to own, more than 5% of our capital stock (except to the extent specifically set forth below), corporations that accumulate earnings to avoid U.S. federal income tax, tax-exempt organizations, banks, financial institutions, insurance companies, brokers, dealers or traders in securities, commodities or currencies, tax-qualified retirement plans, accrual method taxpayers subject to special tax accounting rules under Section 451(b) of the Code, holders subject to the alternative minimum tax or the Medicare contribution tax, holders holding our common stock as part of a hedge, straddle or other risk reduction strategy, conversion transaction or other integrated investment, holders deemed to sell our common stock under the constructive sale provisions of the Code, controlled foreign corporations, passive foreign investment companies and certain former U.S. citizens or long-term residents.

In addition, this discussion does not address the tax treatment of partnerships (or entities or arrangements that are treated as partnerships for U.S. federal income tax purposes) or persons that hold their common stock through such partnerships. If a partnership, including any entity or arrangement treated as a partnership for U.S. federal income tax purposes, holds shares of our common stock, the U.S. federal income tax treatment of a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. Such partners and partnerships should consult their own tax advisors regarding the tax consequences of the purchase, ownership, and disposition of our common stock.

S-14

There can be no assurance that a court or the IRS will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, an IRS ruling with respect to the U.S. federal income tax consequences to a non-U.S. holder of the purchase, ownership or disposition of our common stock.

Distributions on Our Common Stock

Distributions, if any, on our common stock generally will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds our current and accumulated earnings and profits, the excess will be treated as a tax-free return of the non-U.S. holder’s investment, up to such holder’s adjusted tax basis in the common stock. Any remaining excess will be treated as capital gain from the sale or exchange of such common stock, subject to the tax treatment described below in “Gain on Sale, Exchange, or Other Disposition of Our Common Stock.” Any such distribution will also be subject to the tax treatment described below under the heading “FATCA Withholding.”

Dividends paid to a non-U.S. holder will generally be subject to withholding of U.S. federal income tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

Dividends that are treated as effectively connected with a trade or business conducted by a non-U.S. holder within the United States and, if an applicable income tax treaty so provides, that are attributable to a permanent establishment or a fixed base maintained by the non-U.S. holder within the United States, are generally exempt from the 30% withholding tax if the non-U.S. holder satisfies applicable certification and disclosure requirements. However, such U.S. effectively connected income, net of specified deductions and credits, is taxed at the same graduated U.S. federal income tax rates applicable to U.S. persons (as defined in the Code). Any U.S. effectively connected income received by a non-U.S. holder that is a corporation may also, under certain circumstances, be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty between the United States and such holder’s country of residence.

To claim a reduction or exemption from withholding, a non-U.S. holder of our common stock generally will be required to provide (a) a properly executed IRS Form W-8BEN or W-8BEN-E (or successor form) and satisfy applicable certification and other requirements to claim the benefit of an applicable income tax treaty between the United States and such holder’s country of residence or (b) a properly executed IRS Form W-8ECI stating that the dividends are not subject to withholding because they are effectively connected with such non-U.S. holder’s conduct of a trade or business within the United States. Non-U.S. holders are urged to consult their tax advisors regarding their entitlement to benefits under a relevant income tax treaty.

A non-U.S. holder that is eligible for a reduced rate of U.S. withholding tax under an income tax treaty may obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS.

Gain on Sale, Exchange, or Other Disposition of Our Common Stock

Subject to the discussion below regarding backup withholding and FATCA, in general, a non-U.S. holder will not be subject to any U.S. federal income tax on any gain realized upon such holder’s sale, exchange or other disposition of shares of our common stock unless:

S-15

U.S. Federal Estate Tax

The estates of nonresident alien individuals generally are subject to U.S. federal estate tax on property with a U.S. situs. Because we are a U.S. corporation, our common stock will be U.S. situs property and therefore will be included in the taxable estate of a nonresident alien decedent, unless an applicable estate tax treaty between the United States and the decedent’s country of residence provides otherwise. Investors are urged to consult their own tax advisors regarding the U.S. federal estate tax consequences of the ownership or disposition of our common stock.

Information Reporting and Backup Withholding

We generally must report annually to the IRS and to each non-U.S. holder the gross amount of distributions on our common stock paid to such holder, whether or not such distribution is a dividend for U.S. federal income tax purposes, and the tax withheld, if any, with respect to such distributions. Non-U.S. holders will have to comply with specific certification procedures to establish that the holder is not a U.S. person (as defined in the Code) in order to avoid backup withholding at the applicable rate with respect to dividends on our common stock. A non-U.S. holder generally will not be subject to U.S. backup withholding with respect to payments of dividends on our common stock if it certifies its non-U.S. status by providing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI (or successor form), or otherwise establishes an exemption; provided we do not have actual knowledge or reason to know such non-U.S. holder is a U.S. person, as defined in the Code. Dividends paid to non-U.S. holders subject to the U.S. withholding tax, as described above in “Distributions on Our Common Stock,” generally will be exempt from U.S. backup withholding.

S-16

Information reporting and backup withholding will generally apply to the proceeds of a disposition of our common stock by a non-U.S. holder effected by or through the U.S. office of any broker, U.S. or foreign, unless the holder certifies its status as a non-U.S. holder and satisfies certain other requirements, or otherwise establishes an exemption. Generally, information reporting and backup withholding will not apply to a payment of disposition proceeds to a non-U.S. holder where the transaction is effected outside the United States through a non-U.S. office of a broker. However, information reporting but not backup withholding will apply in a manner similar to dispositions effected through a U.S. office of a broker, if a non-U.S. holder sells our common stock through a non-U.S. office of a broker that is:

Non-U.S. holders should consult their own tax advisors regarding the application of the information reporting and backup withholding rules to them.

Copies of information returns may be made available to the tax authorities of the country in which the non-U.S. holder resides or is incorporated under the provisions of a specific treaty or agreement.

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

FATCA Withholding

The Code, U.S. Treasury Regulations and other applicable guidance, commonly referred to as “FATCA,” generally impose a U.S. federal withholding tax of 30% on dividends on stock in a U.S. corporation paid to (i) a “foreign financial institution” (as specifically defined for this purpose), unless such institution enters into an agreement with the U.S. government to, among other things, withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity and debt holders of such institution, as well as certain account holders that are foreign entities with U.S. owners) or otherwise qualifies for an exemption from these rules and (ii) a “non-financial foreign entity” (as defined in the Code), unless such entity provides the withholding agent with either a certification that it does not have any substantial direct or indirect U.S. owners or provides information regarding substantial direct and indirect U.S. owners of the entity, or otherwise qualifies for an exemption from these rules. U.S. Treasury Regulations proposed in December 2018 (and upon which taxpayers and withholding agents are entitled to rely) eliminate possible FATCA withholding on the gross proceeds from any sale or other disposition of shares of stock of a U.S. corporation, previously scheduled to apply beginning January 1, 2019. Under certain circumstances, a non-U.S. holder might be eligible for refunds or credits of such taxes. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this paragraph.

EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE PARTICULAR U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAWS.

UNDERWRITING (CONFLICT OF INTEREST)

We, the Selling Stockholders and the underwriters named below have entered into an underwriting agreement with respect to the shares being offered. Subject to certain conditions, each underwriter has severally agreed to purchase the number of shares indicated in the following table, which includes the shares subject to the Concurrent Share Repurchase, see “Concurrent Share Repurchase.” Goldman Sachs & Co. LLC, BofA Securities, Inc. and RBC Capital Markets, LLC are the representatives of the underwriters.

The underwriters are committed to take and pay for all of the shares being offered, if any are taken, other than the shares covered by the option described below unless and until this option is exercised.

The underwriters have an option to buy up to an additional 1,143,750 shares from the Selling Stockholders to cover sales by the underwriters in the initial offering of the shares or in the open market of a greater number of shares than the total number set forth in the table above. They may exercise that option for 30 days from the date of this prospectus supplement. If any shares are purchased pursuant to this option, the underwriters will severally purchase shares in approximately the same proportion as set forth in the table above.

We intend to purchase from the underwriters 1,375,000 shares of our common stock offered in this offering, at a price per share equal to the price per share to be paid by the underwriters to the Selling Stockholders, as part of our existing stock repurchase program, so long as the total amount of shares we purchase from the underwriters does not exceed $160.0 million. Assuming a repurchase price of $105.28 per share, the last reported sale price per share of our common stock on the NYSE on January 26, 2024, we would purchase 1,375,000 shares of our common stock from the underwriters in the Concurrent Share Repurchase. See “Concurrent Share Repurchase.”

The following table shows the per share and total underwriting discount and commissions to be paid to the underwriters by the Selling Stockholders. The underwriters will not receive any underwriting discount for the shares being repurchased by us pursuant to the Concurrent Share Repurchase. Such amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase 1,143,750 additional shares.

The shares that are not subject to the Concurrent Share Repurchase sold by the underwriters to the public will initially be offered at the public offering price set forth on the cover of this prospectus supplement. Any shares sold by the underwriters to securities dealers may be sold at a discount of up to $     per share from the public offering price. After the initial offering of the shares, the representatives may change the offering price and the other selling terms. The offering of the shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

We, the Selling Stockholders and all of our executive officers and directors have agreed with the underwriters, subject to certain exceptions, not to dispose of or hedge any of their common stock or securities

S-18

convertible into or exchangeable for shares of common stock during the period from the date of this prospectus supplement continuing through the date 30 days after the date of this prospectus supplement, except with the prior written consent of Goldman Sachs & Co. LLC.

The lock-up agreement applicable to us is subject to certain specified exceptions, including: (i) any issuance of common stock, options to purchase shares of common stock, restricted stock units and any other equity incentive compensation issued pursuant to employee benefit plans, qualified stock option plans or other employee compensation plans described in this prospectus supplement; (ii) common stock issued upon exercise of outstanding options, warrants or rights, whether or not issued under one of those plans, and common stock issued upon the exercise of options or the settlement of restricted stock units granted under such plans or under equity plans or similar plans of companies acquired by us in effect on the date of acquisition; and (iii) any issuance of common stock upon the conversion or exchange of convertible or exchangeable securities outstanding as of the date of this prospectus supplement.

The lock-up agreements applicable to the Selling Stockholders and all of our directors and executive officers are subject to specified exceptions, including: (i) bona fide gifts; (ii) transfers to any trust for the direct or indirect benefit of the lock-up party or the immediate family of the lock-up party; (iii) transfers by will or intestacy; (iv) transfers to a partnership, limited liability company or other entity in which the lock-up party and the immediate family of the lock-up party are the legal and beneficial owner of all the outstanding equity securities or similar interests; (v) transfers by operation of law, such as pursuant to a qualified domestic order or in connection with a divorce settlement; (vi) open market transactions after the completion of this offering or transfers to the underwriters in this offering; (vii) (A) the exercise of stock options solely with cash granted pursuant to equity incentive plans described in this prospectus supplement, and the receipt by the lock-up party from us of shares of common stock upon such exercise; (B) transfers to us upon the “net” or “cashless” exercise of stock options or other equity awards granted pursuant to equity incentive plans; (C) transfers for the primary purpose of satisfying any tax or other governmental withholding obligation with respect to any award of equity-based compensation granted pursuant to our equity incentive plans described in this prospectus supplement; or (D) forfeitures to us to satisfy tax withholding requirements of the lock-up party or us upon the vesting, during the restricted period, of equity-based awards granted under equity incentive plans or pursuant to other stock purchase arrangements, in each cased described in this prospectus supplement; (viii) a bona fide third-party tender offer, merger, consolidation or other similar transaction made to all holders of our capital stock; (ix) transfers to us in connection with the repurchase by us of shares of common stock or other securities pursuant to a repurchase right arising upon the termination of a lock-up party’s employment with us; (x) (A) the establishment of a trading plan pursuant to Rule 10b5-1 of the Exchange Act; or (B) transfers pursuant to an existing 10b5-1 trading plan, provided that no such transfers shall be made prior to the closing date of this offering; (xi) if the lock-up party is a corporation, partnership, limited liability company or other business entity, (A) distributions to limited and general partners, members, stockholders or holders of similar interests or (B) transfers to affiliates (as defined in Rule 405 of the Securities Act); (xii) the pledge of shares of common stock as collateral or security pursuant to the Margin Loan Agreements dated as of March 3, 2022 among entities affiliated with Apollo, the lenders party thereto and Barclays Bank plc, and any refinancing or other modification of such margin loan financing or any transfer upon foreclosure or thereafter upon such shares; or (xiii) transfers to the lock-up party’s employer or any affiliate of the lock-up party’s employer as compensation in his or her capacity as a member of our board of directors; provided that, in the case of any transfer or distribution pursuant to (i) through (v), (vii), (xi) and (xiii), the transferee or distributee agrees in writing to be bound by the lock-up restrictions.

Shares of our common stock are listed on the NYSE under the symbol “SNX.”

In connection with this offering, the underwriters may purchase and sell shares of common stock in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of shares than they are required to purchase in this offering, and a short position represents the amount of such sales that have not been

S-19

covered by subsequent purchases. A “covered short position” is a short position that is not greater than the amount of additional shares for which the underwriters’ option described above may be exercised. The underwriters may cover any covered short position by either exercising their option to purchase additional shares or purchasing shares in the open market. In determining the source of shares to cover the covered short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase additional shares pursuant to the option described above. “Naked” short sales are any short sales that create a short position greater than the amount of additional shares for which the option described above may be exercised. The underwriters must cover any such naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the common stock in the open market after pricing that could adversely affect investors who purchase in this offering. Stabilizing transactions consist of various bids for or purchases of common stock made by the underwriters in the open market prior to the completion of this offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representative has repurchased shares sold by or for the account of such underwriter in stabilizing or short covering transactions.

Purchases to cover a short position and stabilizing transactions, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of our stock, and together with the imposition of the penalty bid, may stabilize, maintain or otherwise affect the market price of our common stock. As a result, the price of our common stock may be higher than the price that otherwise might exist in the open market. The underwriters are not required to engage in these activities and may end any of these activities at any time. These transactions may be effected on the NYSE, in the over-the-counter market or otherwise.

Conflict of Interest

Apollo Global Securities, LLC (“AGS”) has a “conflict of interest” within the meaning of FINRA Rule 5121 in this offering because AGS is affiliated with the Selling Stockholders, who are in turn one of our affiliates, and because the net proceeds of this offering will be received by the Selling Stockholders. Accordingly, this offering will be conducted in accordance with the requirements of Financial Industry Regulation Authority (“FINRA”) Rule 5121 regarding a FINRA member firm’s participation in a public offering of securities of an affiliate. Pursuant to that rule, the appointment of a “qualified independent underwriter” is not required in connection with this offering. In accordance with FINRA Rule 5121, neither AGS nor any other affiliated underwriter, agent or dealer of may sell the securities to any account over which it exercises discretionary authority without the specific written approval of the account holder.

S-20

The underwriters and 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.

PROSPECTUS

TD SYNNEX Corporation

Common Stock

This prospectus relates to the offer and resale from time to time by the selling stockholders of TD SYNNEX Corporation listed on page 7 of up to an aggregate of 44,961,612 shares of our common stock, par value $0.001 per share, consisting of up to: (a) 35,199,549 shares of our common stock previously registered for resale by certain entities managed by affiliates of Apollo Global Management, Inc. (the “Apollo Selling Stockholders”) pursuant to the prior registration statement on Form S-3 filed and which became effective automatically on September 2, 2021 (File No. 333-259270) and (b) 9,762,063 shares of our common stock registered for resale by certain entities affiliated with MiTAC Holdings Corporation (the “MiTAC Selling Stockholders” and, together with the Apollo Selling Stockholders, the “Initial Selling Stockholders”) pursuant to this registration statement on Form S-3 of which this prospectus forms a part, as well as the pledgees, donees, transferees, assignees, successors, designees and others who later come to hold any of the Initial Selling Stockholders’ interest in our common stock other than through a public sale (collectively with the Initial Selling Stockholders, the “Selling Stockholders”). The Apollo Selling Stockholders acquired their shares from us in connection with our acquisition of Tiger Parent (AP) Corporation (“Tiger Parent”), the indirect parent entity of Tech Data Corporation, a Florida corporation (“Tech Data”). Such shares of common stock were sold and issued by us to the Apollo Selling Stockholders pursuant to the terms and subject to the conditions of the Agreement and Plan of Merger (the “Merger Agreement”), dated as of March 22, 2021, by and among TD SYNNEX Corporation, a Delaware corporation (“TD SYNNEX,” “we,” “us” or “our”), Spire Sub I, Inc., a Delaware corporation and a wholly-owned subsidiary of SYNNEX (“Merger Sub I”), Spire Sub II, LLC, a Delaware limited liability company and a direct wholly owned subsidiary of SYNNEX (“Merger Sub II”), and Tiger Parent, and the related agreements. In 1992, MiTAC International Corporation (“MiTAC International”), through its wholly owned subsidiary, Silver Star Development, Ltd., acquired a controlling interest in us and, prior to the completion of our initial public offering, had increased its beneficial ownership interest in us to approximately 98%. In September 2013, MiTAC Holdings Corporation (“MiTAC Holdings”) was established through a stock swap from MiTAC International, which is now a wholly owned subsidiary of MiTAC Holdings.

We are not selling any shares of our common stock under this prospectus and we will not receive any of the proceeds from the sale of shares by the Selling Stockholders. Our registration of the shares of our common stock covered by this prospectus does not mean the Selling Stockholders will offer or sell any of the shares of our common stock. The Selling Stockholders may sell the shares of common stock described in this prospectus through a number of different ways and at varying prices, including through public or private transactions at market prices prevailing at the time of sale or at negotiated prices. We provide more information about how the Selling Stockholders may sell their shares of common stock in the section of this prospectus entitled “Plan of Distribution.”

Our common stock is listed on The New York Stock Exchange under the symbol “SNX.” On October 9, 2023, the last reported sale price for our common stock on The New York Stock Exchange was $98.69 per share.

Investing in our common stock involves a high degree of risk. Before investing, you should carefully consider the matters described under the caption “Risk Factors” beginning on page 4.

ABOUT THIS PROSPECTUS

This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission (the “SEC”) as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), utilizing a “shelf” registration process. Under this process, the Selling Stockholders may sell shares of common stock from time to time in one or more offerings through any means described in the section entitled “Plan of Distribution.” Any applicable prospectus supplement may add, update, or change information contained in this prospectus.

You should read this prospectus together with any applicable prospectus supplement, as well as additional information described under the heading “Where You Can Find More Information.” You should rely only on the information contained or incorporated by reference in this prospectus, any accompanying prospectus supplement and any applicable “free writing prospectus.” We have not authorized, and the Selling Stockholders have not authorized, anyone else to provide you with different or additional information. No offer of shares of common stock is being made in any jurisdiction where the offer or sale is not permitted.

You should not assume that the information in this prospectus, any accompanying prospectus supplement, or any document incorporated by reference herein or therein is accurate as of any date other than their respective dates. Our business, financial condition, results of operations, and prospects may have changed since those dates. You should carefully read the entire prospectus, as well as the documents incorporated by reference in the prospectus, any applicable prospectus supplement and any applicable “free writing prospectus” before making an investment decision.

References in this prospectus to the terms “the Company,” “TD SYNNEX,” “SYNNEX,” “we,” “our” and “us” or other similar terms mean TD SYNNEX Corporation and its wholly owned subsidiaries, unless we state otherwise, or the context indicates otherwise.

Throughout this prospectus, when we refer to the shares of our common stock being registered on behalf of the Selling Stockholders, we are referring to all shares of common stock reported to us as held by such stockholders as of October 9, 2023. We agreed to file this prospectus pursuant to an Investor’s Rights Agreement with the Apollo Selling Stockholders dated September 1, 2021 (incorporated by reference to Exhibit 10.1 to the Company’s Current Report on Form 8-K filed with the SEC on September 2, 2021) and a Letter Agreement with the MiTAC Selling Stockholders dated September 3, 2021 (the “MiTAC Letter Agreement”) (incorporated by reference to Exhibit 4.12 to our Annual Report on Form 10-K for the year ended November 30, 2021). Additional information with respect to the Selling Stockholders is contained in this prospectus under the heading “Selling Stockholders.”

When we refer to the Selling Stockholders in this prospectus, we are referring to the entities named in this prospectus as the Initial Selling Stockholders and, as applicable, any donees, pledgees, transferees or other successors-in-interest selling shares of common stock or interests in shares of common stock received after the date of this prospectus from the Initial Selling Stockholders as a gift, pledge, partnership distribution, redemption, repurchase or cancellation, or other non-sale related transfer.

RISK FACTORS

Investing in our securities involves risk. Prior to making a decision about investing in our securities, you should carefully consider the specific factors discussed below and under the heading “Risk Factors” contained in our most recent Annual Report on Form 10-K and most recent Quarterly Reports on Form 10-Q and any other filings we make with the SEC from time to time that are incorporated herein by reference, as well as the “Risk Factors” contained in any prospectus supplement, together with all of the other information contained or incorporated by reference in this prospectus or any prospectus supplement. See “Where You Can Find More Information” in this prospectus. The risks and uncertainties we have described therein and below are not the only risks that we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations. In that case, the trading price of our common stock could decline.

Sales or the availability for sale of a substantial number of shares of our common stock in the public market could cause our stock price to be volatile or fall.

Sales of a substantial number of shares of our common stock in the public market or the perception that these sales might occur could abruptly depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. As of August 31, 2023, we had approximately 92,737,234 shares of our common stock outstanding, 38.0% of which is held by the Apollo Selling Stockholders and 10.5% of which is held by the MiTAC Selling Stockholders. The Selling Stockholders may choose to sell some or all or none of their shares of common stock. The sale or the availability for sale of a large number of shares of our common stock in the public market from time to time could increase the potential for stock price volatility or cause the price of our common stock to decline. Even if we put strategies in place to attempt to address potential or actual volatility, the effectiveness of such strategies is uncertain. In addition, the Selling Stockholders have certain registration rights that require us to register the sale of common stock held by them, including in connection with underwritten offerings. Further, certain of the Selling Stockholders have pledged a significant number of the shares of common stock held by them pursuant to margin loan agreements, and any foreclosure upon those shares could result in sales of a substantial number of shares of our common stock in the public market, which could substantially decrease the market price of our common stock.

Our bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our bylaws provide that the Court of Chancery of the State of Delaware (or, if the Court of Chancery does not have jurisdiction, the federal district court for the District of Delaware) is the exclusive forum for (i) any derivative action or proceeding brought on behalf of the corporation, (ii) any action asserting a claim of breach of fiduciary duty owed by any current or former director, officer, other employee or agent of the corporation to the corporation or the corporation’s stockholders, including a claim alleging the aiding and abetting of such a breach of fiduciary duty, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or the bylaws or the certificate of incorporation or (iv) any action asserting a claim governed by the internal affairs doctrine or asserting an “internal corporate claim”. This choice of forum provision may limit a stockholder’s ability to bring a claim in a different judicial forum that such stockholder views as more favorable for such disputes which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively, if a court were to find the choice of forum provisions contained in our bylaws to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

FORWARD-LOOKING STATEMENTS

Forward-looking statements included in this prospectus, any prospectus supplement, information incorporated by reference herein or therein and any related free-writing prospectus are based on various facts and derived utilizing numerous important assumptions are subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Forward-looking statements include the information concerning our future financial performance, business strategy, projected plans and objectives, as well as projections of macroeconomic and industry trends, which are inherently unreliable due to the multiple factors that impact economic trends, and any such variations may be material. Statements preceded by, followed by or that otherwise include the words “believes,” “expects,” “anticipates,” “intends,” “projects,” “estimates,” “plans,” and similar expressions or future or conditional verbs such as “will,” “should,” “would,” “may” and “could” are generally forward looking in nature and not historical facts. Factors that could cause our actual results to differ materially from those described in the forward-looking statements include, but are not limited to, those discussed in the section entitled “Risk Factors” contained herein and in any Annual Report on Form 10-K and any Quarterly Report on Form 10-Q incorporated by reference in this prospectus and in the section of any related prospectus supplement entitled “Risk Factors.

Except as required by law, we undertake no obligation to update any forward-looking statements in order to reflect any event or circumstance that may arise after the date of this prospectus. However, readers should carefully review the reports and documents we file or furnish from time to time with the SEC, particularly our annual reports on Form 10-K, quarterly reports on Form 10-Q and current reports on Form 8-K. For information about how to obtain a copy of these reports or other documents that we file with the SEC, see “Where You Can Find More Information” in this prospectus.

USE OF PROCEEDS

We will not receive any proceeds from the sale or other disposition by the Selling Stockholders of the shares of our common stock covered hereby, or interests therein. The Selling Stockholders will pay all applicable underwriting fees, discounts and similar charges (pro rata based on the securities sold). The Selling Stockholders shall be entitled to a single counsel at our expense to be selected by the Selling Stockholders.

SELLING STOCKHOLDERS

We are registering for resale an aggregate of up to 44,961,612 shares of our common stock that may be sold by the Initial Selling Stockholders set forth herein, as well as the pledgees, donees, transferees, assignees, successors, designees and others who later come to hold any of the Initial Selling Stockholders’ interest in our common stock other than through a public sale (collectively with the Initial Selling Stockholders, the “Selling Stockholders”). Such shares were sold and issued by us to: (a) the former sole stockholder of Tiger Parent pursuant to the terms of the Merger Agreement and the related agreements, and (b) the MiTAC Selling Stockholders, in each case under an exemption from registration under Section 4(a)(2) of the Securities Act. In January 2023, an aggregate of 5,175,000 shares of common stock were sold by the Apollo Selling Stockholders pursuant to the Prior Registration Statement.

Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to our common stock. Under rules of the SEC, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

The Selling Stockholders may sell some, all, or none of their shares of common stock offered by this prospectus from time to time. Other than the Merger Agreement and the agreements contemplated thereby or described below, we currently have no agreements, arrangements or understandings with the Selling Stockholders regarding the sale of any of the shares of common stock being offered hereunder. Other than the rights provided to the Apollo Selling Stockholders pursuant to that certain Investor’s Rights Agreement dated September 1, 2021 (filed as Exhibit 10.1 to our Current Report on Form 8-K filed with the SEC on September 2, 2021), and the MiTAC Letter Agreement, dated as of September 3, 2021, by and between SYNNEX Corporation, Silver Star Developments Ltd. And Peer Developments Ltd. (filed as Exhibit 4.12 to our Annual Report on Form 10-K for the year ended November 30, 2021) and as otherwise described herein, none of the Selling Stockholders have, and within the past three years have had, any position, office or other material relationship with us or any of our affiliates.

Selling Stockholder information for any additional Selling Stockholders, if any, will be set forth by prospectus supplement to the extent required prior to the time of any offer or sale of such Selling Stockholders’ shares pursuant to this prospectus. Any prospectus supplement may add, update, substitute, or change the information contained in this prospectus, including the identity of the Selling Stockholders and the number of shares registered on their behalf. Any of the Selling Stockholders may sell or otherwise transfer all, some or none of such shares in this offering. See “Plan of Distribution.”

The proceeds of the shares offered by Tiger Holdings will be distributed to certain members of management of the Company. Such members of management had been members of management of Tech Data Corporation and had exchanged their profits interests of Tiger Holdings on August 26, 2021 for the right to receive shares of the Company.

MATERIAL RELATIONSHIPS WITH SELLING STOCKHOLDERS

Apollo

Apollo Global Management, Inc. (“Apollo” and, together with its affiliates (including the Selling Stockholders), the “Apollo Entities”) is an affiliate of the Company. Without giving effect to any resale of shares of common stock pursuant to this prospectus, the Apollo Entities beneficially owned approximately 38.0% of outstanding shares of our common stock.

The Apollo Entities acquired these shares from us in connection with our acquisition of Tiger Parent, the indirect parent entity of Tech Data. Such shares of common stock were sold and issued by us to the Apollo Entities pursuant to the terms and subject to the conditions of the Merger Agreement. Additionally, in connection with the completion of the Mergers, we entered into an Investor Rights Agreement (the “Investor Rights Agreement”) with Tiger Holdings, an affiliate of Apollo. Pursuant to the Investor Rights Agreement, the Apollo Entities have the right to nominate (i) up to four directors if the Apollo Entities own 30% or more of the outstanding shares of our common stock, (ii) up to three directors if the Apollo Entities own between 20% and 30% of the outstanding shares of our common stock, (iii) up to two directors, if the Apollo Entities own between 10% and 20% of the outstanding shares of our common stock or (iv) up to one director, if the Apollo Entities own between 5% and 10% of the outstanding shares of our common stock (such directors nominated by the Apollo Entities, the “Apollo Directors”). The current Apollo Directors are Robert Kalsow-Ramos, Nayaki Nayyar, Matthew Nord, and Merline Saintil. The Investor Rights Agreement also provides that, of the remaining directors who are not Apollo Directors, one director shall be the then-serving Chief Executive Officer of the Company, currently Richard Hume, and the other directors will be nominated in accordance with the provisions of our bylaws and Certificate of Incorporation. The Apollo Directors must fulfill their pro rata portion of any diversity requirements pursuant to law, stock exchange rules, or other regulatory requirements based on the percentage of our board of directors consisting of Apollo Directors.

Under the Investor Rights Agreement, we have waived the corporate opportunity doctrine to the extent permitted under the Delaware General Corporation Law with respect to the Apollo Directors and Apollo Entities, so long as such person is not an employee of the Company or our subsidiaries (the “Covered Persons”). Specifically, we agreed that the Covered Persons do not have a duty to refrain from: (i) investing in or conducting any business of any kind, (ii) doing business with our or any of our affiliates’ clients, customers, vendors or lessors, or (iii) making any investments in any kind of property in which we may make investments. Further, we agreed, among other things, subject to any express agreement otherwise that may from time to time be in effect, that if a Covered Person acquires knowledge of a potential transaction which may constitute a corporate opportunity for both (a) the Covered Person outside of his or her capacity as a member of our board of directors and (b) the Company, then the Covered Person shall not have any duty to offer or communicate information regarding such corporate opportunity to us, and we renounced any interest or expectancy in any potential transaction or matter of which the Covered Person acquires knowledge, except for any corporate opportunity which is expressly offered to a Covered Person in writing solely in his or her capacity as a member of our board of directors, or as expressly agreed otherwise.

In addition, we granted the Apollo Entities certain registration rights pursuant to the Investor Rights Agreement. Subject to several exceptions, including our right to defer a demand registration, underwritten shelf registration or non-underwritten shelf registration under certain circumstances, the Apollo Entities have the right to require us to register the sale of the shares of common stock held by them on Form S-3, subject to offering size and other restrictions. The Apollo Entities also have the right to request marketed and non-marketed underwritten offerings using a shelf registration statement. If we propose to file certain types of registration statements under the Securities Act with respect to an offering of shares of common stock (including for sale by us or at the request of any holder of registration rights), then we will be required to offer the Apollo Entities the opportunity to register any number of shares of common stock that they request, on the terms and conditions set forth in the Investor Rights Agreement (customarily known as “piggyback rights”). The registration rights granted under the

10

Investor Rights Agreement are subject to customary restrictions including, if a registration is underwritten, any limitations on the number of shares to be included in the underwritten offering as reasonably advised by the managing underwriter or underwriters. All expenses of registration under the Investor Rights Agreement, including the legal fees of counsel chosen by the Apollo Entities, but excluding all applicable underwriting fees, discounts and similar charges, will be paid by us. The Investor Rights Agreement also contains customary indemnification and contribution provisions. Any sales in the public market of any shares of common stock registrable pursuant to the registration rights granted under the Investor Rights Agreement could depress the market price of our shares of common stock. See “Risk Factors—Sales or the availability for sale of a substantial number of shares of our common stock in the public market could cause our stock price to be volatile or fall.”

Our director Robert Kalsow-Ramos is a Partner, Private Equity at Apollo and our director Matthew Nord is a Partner and Co-Head of Private Equity at Apollo.

MiTAC Holdings Corporation

We have a business relationship with MiTAC International Corporation (“MiTAC International”), a publicly-traded company in Taiwan that began in 1992 when it became our primary investor through its affiliates. In September 2013, MiTAC Holdings Corporation (“MiTAC Holdings”) was established through a stock swap from MiTAC International and became a publicly traded company on the Taiwan Stock Exchange. MiTAC International is now a wholly owned subsidiary of MiTAC Holdings. As of August 31, 2023, MiTAC Holdings and its affiliates beneficially owned approximately 10.5% of our common stock. Matthew Miau, our Chair Emeritus of the Board and a director, is the Chairman of MiTAC Holdings and a director or officer of MiTAC Holdings’ affiliates.

Until July 31, 2010, we worked with MiTAC Holdings on OEM outsourcing and jointly marketed MiTAC Holdings’ design and electronic manufacturing services and our contract assembly capabilities. On July 31, 2010, MiTAC Holdings purchased certain assets related to the contract assembly business including inventory and customer contracts, primarily related to customers then being jointly serviced by MiTAC Holdings and us. We made payments of $0.4 million and $0.2 million to MiTAC Holdings and its affiliates for reimbursement of rent and overhead costs for facilities used by us during fiscal years ended November 30, 2022 and 2021, respectively.

We purchased inventories and services from MiTAC Holdings and its affiliates totaling $257.7 million, $199.7 and $211.9 million during fiscal years 2022, 2021 and 2020, respectively. Our sales to MiTAC Holdings, and its affiliates during fiscal years 2022, 2021 and 2020 totaled $1.3 million, $0.6 million and $0.8 million, respectively. Most of the purchases and sales in 2022, 2021 and 2020 were pursuant to the agreements mentioned under the heading “Agreements with MiTAC Holdings and Affiliates” below.

Our business relationship with MiTAC Holdings and its affiliates has been informal and is not governed by long-term commitments or arrangements with respect to pricing terms, revenue or capacity commitments. We negotiate pricing and other material terms on a case-by-case basis with MiTAC Holdings and its affiliates. We have adopted a policy requiring that material transactions with MiTAC Holdings or its related parties be approved by the Audit Committee, which is composed solely of independent directors. In addition, Matthew Miau’s compensation is approved by the Nominating and Corporate Governance Committee and will be approved by the Compensation Committee going forward, which are also composed solely of independent directors. While the ownership structure of MiTAC Holdings and its affiliates is complex, it has not had a material adverse effect on our business in the past, and we do not expect it to do so in the future.

Agreements with MiTAC Holdings and Affiliates

We have entered into several additional agreements with affiliates of MiTAC Holdings. These agreements do not constitute contracts or obligations by any party to purchase products or services from the other parties, nor do they restrict our ability to conduct our business. Accordingly, we do not believe that the termination of any of

11

these agreements would have a material adverse effect on our business. Pursuant to these agreements, the terms for contracted services or purchased products are individually negotiated and, if agreed upon by the parties, such terms are included in a purchase order. In the fiscal years ended November 30, 2022, 2021 and 2020, we paid an aggregate of approximately $257.7 million, $199.7 million and $211.9 million to MiTAC Holdings and its affiliates, most of which was paid pursuant to certain distribution and supply agreements.

Letter Agreement. In connection with the Mergers and the Investor Rights Agreement, we entered into a letter agreement (the “Letter Agreement”) with Silver Star Developments Ltd., Peer Developments Ltd., and any of their affiliates that becomes an owner of TD SYNNEX common stock (the “MiTAC Stockholders”). Under the Letter Agreement, we have agreed that, in the event we file a registration statement with respect to an underwritten offering or a shelf registration statement, whether on our own account or otherwise, or we receive an underwritten shelf take-down notice, then the MiTAC Stockholders shall be given notice thereof, and shall be entitled to include in such filings the shares of TD SYNNEX common stock held by them, subject to certain underwriter cutbacks.

For more information on these relationships, please refer to the 2022 Annual Report, which is incorporated herein by reference.

PLAN OF DISTRIBUTION

The Selling Stockholders may, from time to time in one or more transactions on The New York Stock Exchange or any other organized market where our shares of common stock may be traded, sell any or all of their shares of our common stock offered hereby through underwriters, dealers or agents, directly to one or more purchasers or through a combination of any such methods of sale. The Selling Stockholders may distribute the shares of our common stock offered hereby from time to time in one or more transactions:

The Selling Stockholders may use any one or more of the following methods when selling the shares offered hereby:

In addition, any shares covered by this prospectus that qualify for resale pursuant to Rule 144 under the Securities Act may be sold under Rule 144 rather than under this prospectus.

If the Selling Stockholders effect such transactions by selling shares of common stock offered hereby to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the Selling Stockholders or commissions from purchasers of the shares of common stock offered hereby for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). The Selling Stockholders reserve the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from sales of our common stock by the Selling Stockholders.

13

The Selling Stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of common stock offered hereby and owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell such shares of common stock from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act, amending, if necessary, the list of Selling Stockholders to include the pledgee, transferee or other successors in interest as Selling Stockholders under this prospectus. The Selling Stockholders also may transfer and donate the shares of common stock offered hereby in other circumstances, in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In addition, a Selling Stockholder that is an entity may elect to make a pro rata in-kind distribution of securities to its members, partners or stockholders or purchase or redeem interests held in such entity by its members, partners or stockholders in exchange for securities, in each case pursuant to the registration statement of which this prospectus is a part by delivering a prospectus with a plan of distribution. Such members, partners or stockholders (unless our affiliate) would thereby receive freely tradeable securities pursuant to the distribution through a registration statement. To the extent a distributee is an affiliate of ours (or to the extent otherwise required by law), we may file a prospectus supplement in order to permit the distributees to use the prospectus to resell the securities acquired in the distribution.

In connection with the sale of our common stock or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The Selling Stockholders may also sell shares of our common stock short and deliver these securities to close out the short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that participate in the distribution of the shares of common stock covered by this prospectus may be deemed to be “underwriters” within the meaning of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling Stockholders who are deemed to be “underwriters” within the meaning of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act. To the extent required, the shares of our common stock to be sold, the names of the Selling Stockholders, the respective purchase prices and public offering prices, the names of any agents or dealers, and any applicable discounts, commissions, concessions or other compensation with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus. Underwriters and their controlling persons, dealers and agents may be entitled, under agreements entered into with us and the Selling Stockholders, to indemnification against and contribution toward specific civil liabilities, including liabilities under the Securities Act.

We have agreed to indemnify the Selling Stockholders against certain liabilities, including liabilities under the Securities Act, relating to the registration of the shares offered by this prospectus.

Under the securities laws of some states, the shares of common stock offered hereby may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the shares of common stock offered hereby may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

There can be no assurance that the Selling Stockholders will sell any or all of the shares of common stock registered pursuant to the registration statement of which this prospectus forms a part.

14

The Selling Stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act, and the rules and regulations thereunder, including, without limitation, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of common stock offered hereby by the Selling Stockholders and any other participating person. Regulation M may also restrict the ability of any person engaged in the distribution of the shares of common stock offered hereby to engage in market-making activities with respect to the shares of common stock offered hereby. All of the foregoing may affect the marketability of the shares of common stock offered hereby and the ability of any person or entity to engage in market-making activities with respect to the shares of common stock offered hereby.

Once sold under the registration statement, of which this prospectus forms a part, the shares of common stock offered hereby will be freely tradable in the hands of persons other than our affiliates.
