LPL Financial Holdings Inc.

LPL Holdings, Inc. (the “Issuer”) is offering $     aggregate principal amount of    % Senior Notes due 20  (the “20  Notes”) and $    aggregate principal amount of %    Senior Notes due 20  (the “20  Notes”). We refer to the 20  Notes and the 20  Notes collectively as the “Notes.”

The 20  Notes will bear interest at the rate of     % per year. The 20  Notes will mature on     , 20  . The 20  Notes will bear interest at the rate of    % per year. The 20  Notes will mature on     , 20  . The Issuer will pay interest on the Notes semi-annually in cash in arrears on and of each year, beginning on    and    ending on the applicable maturity date.

We intend to use the net proceeds from this offering of our Notes for general corporate purposes, including to repay outstanding borrowings under our Revolving Credit Facility (as defined herein) and to finance the acquisition (the “Atria Acquisition”) of Atria Wealth Solutions, Inc. (“Atria”). See “Use of Proceeds.”

On February 13, 2024, LPL Financial Holdings Inc., the Issuer’s parent company (the “Guarantor”), announced that the Issuer had entered into a definitive purchase agreement (the “Atria Agreement”) to acquire Atria. This offering is not conditioned upon the completion of the Atria Acquisition. However, if (i) the consummation of the Atria Acquisition does not occur prior to March 7, 2025, (ii) we notify the trustee and the holders of the 20  Notes that we will not pursue the consummation of the Atria Acquisition or (iii) the Atria Agreement has been terminated without the consummation of the Atria Acquisition, the 20 Notes will be subject to a special mandatory redemption upon the terms and at the redemption price set forth in this prospectus supplement under “Description of Notes—Special Mandatory Redemption.” The 20  Notes will not be subject to any special mandatory redemption if the Atria Acquisition is not completed.

We may redeem the Notes, in whole or in part, at any time or from time to time, prior to their maturity at the applicable redemption price described under “Description of Notes—Optional Redemption,” plus any accrued and unpaid interest thereon to, but excluding, the redemption date for the Notes.

The Notes will be fully and unconditionally guaranteed on a senior unsecured basis by the Guarantor (the “guarantee”). The Notes will be senior unsecured obligations of the Issuer that rank equally in right of payment with all of the Issuer’s other unsecured and unsubordinated indebtedness and that rank senior in right of payment to all of the Issuer’s future subordinated debt. The Notes will be effectively subordinated to the Issuer’s existing and future secured obligations (including obligations under the Senior Secured Credit Facilities (as defined herein)) to the extent of the value of the collateral securing such obligations and will be structurally subordinated to all of the existing and future liabilities of the Issuer’s subsidiaries. The guarantee will be a senior unsecured obligation of the Guarantor that ranks equally in right of payment with all of the Guarantor’s existing and future senior unsecured obligations that are not expressly subordinated to the guarantee. The guarantee will be effectively subordinated to the Guarantor’s future secured obligations to the extent of the value of the collateral securing such obligations and will be structurally subordinated to all of the existing and future liabilities of the Guarantor’s subsidiaries. The guarantee will be senior in right of payment to all of the Guarantor’s future subordinated debt.

Investing in the Notes involves significant risks. See “Risk Factors” beginning on page S-15 of this prospectus supplement and on page 2 in the accompanying prospectus.

We do not intend to apply for listing of the Notes on any securities exchange. Currently, there are no public markets for the Notes.

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

The underwriters expect to deliver the Notes in book-entry form only through the facilities of The Depository Trust Company for the account of its direct and indirect participants, including Euroclear Bank SA/NV and Clearstream Banking S.A., on or about     , 2024, which is the fifth business day following the date of this prospectus supplement (such settlement being referred to as “T+5”). Purchasers of the Notes should note that trading of the Notes may be affected by this settlement date. See “Underwriting (Conflicts of Interest).”

Before purchasing any Notes, you should carefully read both this prospectus supplement and the accompanying prospectus, together with the additional information incorporated by reference in this prospectus supplement.

You should rely only on the information contained in this prospectus supplement, the accompanying prospectus, the documents incorporated by reference and any written communication from us or the underwriters specifying the final terms of this offering. We have not, and the underwriters have not, authorized anyone to provide you with information that is different. This prospectus supplement and the accompanying prospectus may only be used where it is legal to sell these securities. The information in this prospectus supplement and the accompanying prospectus may only be accurate as of their respective dates and the information in the incorporated documents is only accurate as of their respective dates. Our business, financial condition, results of operations and prospects may have changed since the date of such information.

The distribution of this prospectus supplement and the accompanying prospectus and the offering of the Notes in certain jurisdictions may be restricted by law. Persons into whose possession this prospectus supplement and the accompanying prospectus come should inform themselves about, and observe, any such restrictions. This prospectus supplement and the accompanying prospectus do not constitute, and may not be used in connection with, an offer or solicitation by anyone in any jurisdiction in which such offer or solicitation is not authorized or in which the person making such offer or solicitation is not qualified to do so or to any person to whom it is unlawful to make such offer or solicitation.

Except as otherwise indicated or as context otherwise requires, references in this prospectus supplement to “LPL,” “we,” “us,” “our,” and the “Company” mean LPL Financial Holdings Inc.

NON-GAAP FINANCIAL MEASURES

This prospectus supplement presents certain “non-GAAP measures” as a supplement to LPLFH’s consolidated results presented in accordance with generally accepted accounting principles (“GAAP”), such as Gross Profit, Credit Agreement EBITDA and Core G&A. Non-GAAP measures have limitations as analytical tools. They are not presentations made in accordance with GAAP, are not measures of financial condition or liquidity, and should not be considered as an alternative to profit or loss for the period determined in accordance with GAAP or operating cash flows determined in accordance with GAAP. Non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider such performance measures in isolation from, or as a substitute analysis for, our results of operations as determined in accordance with GAAP. Definitions and reconciliations of certain non-GAAP measures to the most directly comparable GAAP measures are provided in “Summary—Summary Consolidated Financial and Other Data.”

RISK FACTORS

An investment in the Notes involves a high degree of risk. In addition to the other information in this prospectus supplement and the accompanying prospectus, prospective investors should carefully consider the following risks together with the other information contained and incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment in the Notes. The risks described below are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect our business and operations. If any of the following risks actually occur, our business, financial condition, operating results or growth prospects could be materially adversely affected, which, in turn, could adversely affect our ability to pay interest or principal on the Notes. In such a case, you may lose all or part of your original investment. We cannot assure you that any of the events discussed in the risk factors below will not occur. Along with the risks and uncertainties described below, you should carefully consider the risks and uncertainties described in the sections entitled “Forward- Looking Statements” in this prospectus supplement and in Item 1A under the heading “Risk Factors” in our 2023 Annual Report, which is incorporated by reference in this prospectus supplement.

Risks Related to our Indebtedness and the Notes

Our substantial debt could limit our ability to fund operations, expose us to interest rate volatility, limit our ability to raise additional capital and have a material adverse effect on our ability to fulfill our obligations under the Notes and on our business and prospects generally.

We have a substantial amount of debt and have significant debt service obligations. As of March 31, 2024, on an as adjusted basis after giving effect to the amount of borrowings we intend to repay under the Revolving Credit Facility with a portion of the proceeds from this offering, additional borrowings and prepayments under the Existing Revolving Credit Facility after March 31, 2024 and the expected increase in the available capacity under the Revolving Credit Facility to $2,250.0 million, the Issuer’s aggregate outstanding debt would have been $    and the Issuer would have had $    of available capacity under the Revolving Credit Facility and the Issuer’s subsidiaries would have had $1,200.0 million or more available under LPL Financial’s five lines of credit and revolving credit facility, in each case, subject to compliance with certain conditions. Two of LPL Financial’s lines of credit have unspecified limits, both of which are primarily dependent on our ability to provide sufficient collateral, and three lines of credit and revolving credit facility have a total limit of $1,200.0 million. There can be no assurance that the increase in the available capacity under the Revolving Credit Facility will occur. This offering is not contingent on the completion of any such transaction.

Our substantial debt, combined with our other financial obligations and contractual commitments, could have important consequences to you, including the following:

S-15

While the documents governing certain of our other outstanding senior indebtedness may require the Issuer to repay or repurchase such outstanding senior indebtedness upon the occurrence of a change of control, the Indenture does not require the Issuer to repurchase the Notes upon the occurrence of a change of control.

The documents governing our other outstanding senior indebtedness other than the indenture governing our 6.750% Senior Notes due 2028 (the “2028 Notes”) provide that, if a change of control occurs, the Issuer may be required, as applicable, to repay such indebtedness or to give holders of such notes an opportunity to sell their notes to the Issuer at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest. The Indenture does not require the Issuer to repurchase the Notes upon the occurrence of a change of control.

In addition, upon the occurrence of a change of control, our level of debt may prevent us from raising the funds necessary to repay outstanding borrowings under our Senior Secured Credit Facilities pursuant to the Credit Agreement or to repurchase all of the notes tendered to us pursuant to the indentures governing our other senior debt securities, which may result in a default or an event of default under the respective agreement and may consequently result in a default or an event of default under the Indenture pursuant to the cross-default provision contained therein.

We, including our subsidiaries, will have the ability to incur substantial additional debt, which may intensify the risks associated with our existing debt, including our ability to service our existing and future indebtedness, including the Notes.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. Although the Senior Secured Credit Facilities contain restrictions on the incurrence of additional indebtedness, these restrictions may change and are subject to a number of significant qualifications and exceptions and, under certain circumstances, the amount of indebtedness that could be incurred in compliance with these restrictions could be substantial. As of March 31, 2024, on an as adjusted basis after giving effect to the amount of borrowings we intend to repay under the Revolving Credit Facility with a portion of the proceeds from this offering, additional borrowings and prepayments under the Existing Revolving Credit Facility after March 31, 2024 and the expected increase in the available capacity under the Revolving Credit Facility to $2,250.0 million, the Issuer would have had $    of available capacity under the Revolving Credit Facility and the Issuer’s subsidiaries would have had $1,200.0 million or more available under LPL Financial’s five lines of credit and revolving credit facility, in each case, subject to compliance with certain conditions. Two of LPL Financial’s lines of credit have unspecified limits, both of which are primarily dependent on our ability to provide sufficient collateral, and three lines of credit and revolving credit facility have a total limit of $1,200.0 million. Under the Credit Agreement, the Issuer has the right to request additional commitments for new term loans, new revolving credit commitments and increases to then-existing term loans and revolving credit commitments in an aggregate principal amount not to exceed (i) the greater of $500.0 million and 100% of our

S-16

Consolidated EBITDA (as defined in the Credit Agreement) and (ii) the amount of additional commitments such that the senior secured net leverage ratio shall be no greater than 4.0 to 1.0 after giving effect to such commitments (assuming any such new or increased revolving commitments are fully borrowed). The Issuer may also incur additional debt from time to time, subject to the restrictions contained in our Senior Secured Credit Facilities. If we incur additional debt above the levels in effect upon the closing of the offering, the risks associated with our substantial existing debt, including our ability to service our debt, could intensify.

We may not be able to generate sufficient cash to service all of our indebtedness, including the Notes, and may be forced to take other actions to satisfy our obligations under our indebtedness, which may not be successful.

Our ability to make scheduled payments on or to refinance our debt obligations depends on our financial condition and operating performance, which is subject to prevailing economic and competitive conditions and to certain financial, business and other factors beyond our control. We may not be able to maintain a level of cash flows from operating activities sufficient to permit us to pay the principal, premium, if any, and interest on our indebtedness, including the Notes.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance our indebtedness, including the Notes. The 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 terms of existing or future debt instruments and the Indenture may restrict us from adopting some of these alternatives. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness. In the absence of such operating results and resources, we could face substantial liquidity problems and might be required to dispose of material assets or operations to meet our debt service and other obligations. Our Senior Secured Credit Facilities and the indentures governing our other senior debt securities restrict our ability to dispose of assets and use the proceeds from the disposition. We may not be able to consummate those dispositions or to obtain the proceeds that we could realize from them, and these proceeds may not be adequate to meet any debt service obligations then due. These alternative measures may not be successful and may not permit us to meet our scheduled debt service obligations.

Each of the Issuer and the Guarantor is a holding company and relies on dividends, distributions and other payments, advances and transfers of funds from its subsidiaries to meet its debt service and other obligations.

Neither the Issuer nor the Guarantor has direct operations and each of the Issuer and the Guarantor derives all of its cash flow from its subsidiaries. Because each of the Issuer and the Guarantor conducts its operations through subsidiaries, such entity depends on its subsidiaries for dividends and other payments or distributions to meet any existing or future debt service and other obligations. Our subsidiaries will not have any obligation to pay amounts due on the Notes or to make funds available for that purpose. Each subsidiary is a distinct legal entity, and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. The deterioration of the earnings from, or other available assets of, the Issuer’s and the Guarantor’s respective subsidiaries for any reason could limit or impair their ability to pay dividends or other distributions to the Issuer or the Guarantor. In addition, our broker-dealer subsidiaries are members of FINRA, and FINRA regulations restrict dividends in excess of 10% of a member firm’s excess net capital without FINRA’s prior approval. Compliance with this regulation may impede our ability to receive dividends from our broker-dealer subsidiaries.

The Notes will be structurally subordinated to all of the existing and future liabilities of the Issuer’s subsidiaries, and the guarantee will be structurally subordinated to all of the existing and future liabilities of the Guarantor’s subsidiaries.

The Issuer’s and the Guarantor’s right to receive any assets of any of their respective subsidiaries upon their bankruptcy, liquidation or reorganization, and therefore the right of the holders of the Notes to participate in

S-17

those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors. As of March 31, 2024, the Issuer’s subsidiaries had liabilities of $3,829.7 million (excluding intercompany liabilities). Even if the Issuer or the Guarantor were a creditor of any of their respective subsidiaries, its right as a creditor would be subordinate to any security interest in the assets of such subsidiaries and any indebtedness of such subsidiaries senior to that held by it.

Additionally, all obligations under the Senior Secured Credit Facilities, as well as certain hedging and cash management arrangements, are jointly and severally, fully and unconditionally, guaranteed on a senior secured basis by each of the Guarantor and certain of the Issuer’s direct and indirect domestic subsidiaries. Further, our other senior debt securities other than the 2028 Notes and the Notes would be required to be guaranteed by two of the Issuer’s subsidiaries, LPL Capital Partners, Inc. and LPLIA, in the event that the relevant series of notes ceases to have an investment grade rating (as defined in the applicable indenture) by either Moody’s or S&P (each as defined in the applicable indenture).

As of March 31, 2024, LPL Capital Partners, Inc. and LPLIA had:

We have made only limited covenants in the Indenture governing the Notes, and these limited covenants may not protect your investment.

The Indenture governing the Notes does not:

Furthermore, the Indenture for the Notes does not require us to repurchase the Notes upon the occurrence of a change of control. We could engage in many types of transactions, such as acquisitions, refinancings or recapitalizations, that could substantially affect our capital structure and the value of the Notes. For these reasons, you should not consider the covenants in the Indenture or the repurchase features of the Notes as a significant factor in evaluating whether to invest in the Notes.

The Notes are unsecured obligations, and our assets may be insufficient to pay amounts due on the Notes. The right of holders of the Notes to receive payments on the Notes is effectively subordinated to the rights of lenders who have a security interest in our assets, to the extent of the value of those assets.

The Notes and the guarantee are unsecured obligations that will effectively be subordinated in right of payment to all of the Issuer’s secured debt to the extent of the value of the collateral securing such debt. Debt

S-18

outstanding under the Senior Secured Credit Facilities is secured by perfected first priority pledges of and security interests in substantially all of the assets of the Issuer and each of its wholly-owned material restricted domestic subsidiaries that guarantees the Issuer’s obligations under the Credit Agreement, including all present and future shares of capital stock of the Issuer and certain subsidiary guarantors and the present and future shares of capital stock of each of their respective material restricted domestic subsidiaries and 65% of all capital stock of each of their material restricted first-tier foreign subsidiaries, except as prohibited by law and subject to other exceptions.

As of March 31, 2024, on an as adjusted basis after giving effect to the amount of borrowings we intend to repay under the Revolving Credit Facility with a portion of the proceeds from this offering, additional borrowings and prepayments under the Existing Revolving Credit Facility after March 31, 2024 and the expected increase in the available capacity under the Revolving Credit Facility to $2,250.0 million, the Issuer would have had $    of senior secured debt under the Senior Secured Credit Facilities and $    of available capacity under the Revolving Credit Facility and the Issuer’s subsidiaries would have had $1,200.0 million or more available under LPL Financial’s five lines of credit and revolving credit facility, in each case, subject to compliance with certain conditions. Under the Credit Agreement, we have the right to request additional commitments for new term loans, new revolving credit commitments and increases to then-existing term loans and revolving credit commitments, all of which may be effectively senior to the Notes to the extent of the value of the assets securing that debt. In addition, we may incur additional secured debt. There can be no assurance that the increase in the available capacity under the Revolving Credit Facility will occur. This offering is not contingent on the completion of any such transaction.

Because the Notes and the guarantee are unsecured obligations, the right of repayment of holders of the Notes may be compromised if any of the following events were to occur:

If any of these events were to occur, the secured lenders could foreclose on the pledged stock of the Issuer’s subsidiaries and on the Issuer’s and its subsidiaries’ assets in which they have been granted a security interest, in each case to your exclusion, even if at that time an event of default exists under the Indenture. As a result, upon the occurrence of any of these events, there may not be sufficient funds to pay amounts due on the Notes and the guarantee.

The Credit Agreement contains covenants which impose significant operational and financial restrictions on us, and the failure to comply with these covenants would result in an event of default under the Credit Agreement.

The Credit Agreement imposes, and the terms of any future debt may impose, on us operating and other restrictions. These restrictions affect, and in many respects limit or prohibit, among other things, the Issuer’s ability to:

S-19

Certain covenants set forth in the indentures governing our other senior debt securities are currently suspended; however, these covenants would be automatically reinstated if the relevant series of notes ceases to have an investment grade rating by either Moody’s or S&P. Such covenants do not apply to the 2028 Notes.

The terms of the Revolving Credit Facility in the Credit Agreement also require us to achieve and maintain compliance with specified financial ratios. The restrictions contained in the Credit Agreement could:

A breach of any of these restrictive covenants or our inability to comply with the required financial ratios would result in a default under some or all of the debt agreements. During the occurrence and continuance of a default, lenders under our Senior Secured Credit Facilities may elect to declare all outstanding borrowings, together with accrued interest and other fees, to be immediately due and payable, which may result in an event of default under the Indenture and the indentures governing our other senior debt securities. The lenders also have the right in these circumstances to terminate any commitments they have to provide further borrowings. Additionally, our Credit Agreement contains a cross-default provision, which generally causes a default or event of default under the Credit Agreement upon a qualifying default or event of default under any other debt instrument and each of the Indenture and the indentures governing our other senior debt securities contains a cross-acceleration provision. If we are unable to repay outstanding borrowings when due, the lenders under our Senior Secured Credit Facilities also have the right to proceed against the collateral granted to them to secure the debt. If lenders under the Senior Secured Credit Facilities accelerate the debt thereunder, then the obligations under the Notes and our other senior debt securities may be accelerated. We cannot provide assurance that, if the indebtedness under our Senior Secured Credit Facilities, the Notes and our other senior debt securities were to be accelerated, our assets would be sufficient to repay in full that indebtedness and our other indebtedness. If not cured or waived, such acceleration could have a material adverse effect on our business and our prospects.

Your ability to transfer the Notes may be limited by the absence of active trading markets, and there is no assurance that any active trading market will exist for the Notes.

Each series of the Notes are a new issue of securities for which there is no established market. We do not intend to apply for the Notes of any series to be listed on any securities exchange or to arrange for their quotation on any automated dealer quotation system. We have been informed by certain of the underwriters that they intend to make a market in the Notes of each series after we complete this offering. However, those underwriters are not obligated to make a market in the Notes of any series and they may cease their market-making activities at any time without notice. As a result, we cannot assure you that active trading markets will develop for the Notes, and if developed, that they will be maintained. The liquidity of trading markets, if any, for the Notes, and the market prices quoted for the Notes, may experience similar disruptions and any such disruptions may adversely affect

S-20

the prices at which you may sell your Notes. In addition, subsequent to their initial issuances, the Notes may trade at discounts from their initial offering prices, depending upon prevailing interest rates, the market for similar notes, our financial and operating performance, and other factors.

Any decline in the ratings of our corporate credit or the ratings of the Notes could adversely affect the value of the Notes or impact our ability to access capital.

Any decline in the ratings of our corporate credit or the Notes or any indications from the rating agencies that their ratings on our corporate credit or the Notes are under surveillance or review with possible negative implications could adversely affect the value of the Notes and you may not be able to resell your Notes without a substantial discount. In addition, any decline in the ratings of our corporate credit or the Notes could increase our cost of financing and limit our ability to refinance maturing liabilities or access the capital markets to meet liquidity needs. Credit ratings are not recommendations to purchase, hold or sell the Notes.

Redemption of the Notes prior to their maturity may adversely affect your return on the Notes.

We have the right to redeem some or all of the Notes prior to maturity, as described under “Description of Notes—Optional Redemption.” 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 proceeds in a comparable security at an effective interest rate as high as that of the Notes redeemed.

In the event of a special mandatory redemption, holders of the 20  Notes may not obtain their expected return on such Notes.

If we redeem the 20 Notes pursuant to the special mandatory redemption provisions, holders of those notes may not obtain their expected return on such Notes and may not be able to reinvest the proceeds from such special mandatory redemption in an investment that results in a comparable return. In addition, as a result of the special mandatory redemption provisions of the 20 Notes, the trading prices of such Notes may not reflect the financial results of our business or macroeconomic factors. Holders of the 20  Notes will have no rights under the special mandatory redemption provisions as long as the Atria Acquisition closes, nor will they have any rights to require us to repurchase their 20  Notes if, between the closing of this offering and the closing of the Atria Acquisition, we experience any changes (including any material changes) in our business or financial condition, or if the terms of the Atria Agreement change, including in material respects.

We may be unable to redeem any or all of the 20  Notes in the event of the special mandatory redemption.

The closing of this offering is not conditioned upon, and is expected to be consummated before, the consummation of the Atria Acquisition, which is expected to occur in the second half of 2024, subject to receipt of regulatory approval and other closing conditions. The Atria Acquisition may not be consummated within the time frame specified under “Description of Notes–Special Mandatory Redemption” or at all. If a Special Mandatory Redemption Trigger has occurred, we must redeem all of the 20  Notes at a redemption price equal to 101% of the aggregate principal amount of such Notes, plus accrued and unpaid interest to, but excluding the date of the special mandatory redemption. We are not obligated to place the net proceeds from the sale of the 20  Notes in escrow prior to the consummation of the Atria Acquisition or to provide a security interest in those proceeds, and the indenture governing the 20  Notes imposes no restrictions on our use of these proceeds during that time. Accordingly, we may need to fund the special mandatory redemption using proceeds that we have voluntarily retained and from other sources of liquidity. In the event of a special mandatory redemption, we may not have sufficient funds to purchase any or all of the 20  Notes, which would constitute an event of default under the Indenture, which could result in defaults under certain of our other existing or future debt agreements and have material adverse consequences for us and the holders of the Notes.

S-21

If the Atria Acquisition does not close, the 20  Notes will not be subject to any special mandatory redemption.

If the Atria Acquisition is not completed, the 20  Notes will not be subject to any special mandatory redemption and will remain outstanding. Any failure to close the Atria Acquisition, as well as any resulting adverse effects on our business and financial results, could have a material adverse impact on the trading market for, or trading value of, the 20  Notes.

USE OF PROCEEDS

The net proceeds from this offering are expected to be approximately $    , after deduction of the underwriters’ discount and estimated expenses payable by us in connection with the transactions described herein.

We intend to use the net proceeds from this offering of Notes for general corporate purposes, including to repay outstanding borrowings under our Revolving Credit Facility and to finance the Atria Acquisition.

As of March 31, 2024, the Issuer had outstanding borrowings of $401.0 million under the Existing Revolving Credit Facility and, as of the date of this prospectus supplement, the Issuer had outstanding borrowings of $334.0 million under the Existing Revolving Credit Facility. Borrowings under the Existing Revolving Credit Facility bear interest, at the borrower’s election, at a rate per annum ranging from either (a) 112.5 to 187.5 basis points over the Secured Overnight Financing Rate for an interest period of one, three or six months plus 10 basis points or (b) 12.5 to 87.5 basis points over the alternate base rate (the greatest of (i) the NYFRB Rate plus 1/2 of 1%, (ii) the Prime Rate and (iii) the Adjusted Term SOFR Rate for a one month Interest Period plus 1%, each as defined in the Credit Agreement) depending on the Debt Ratings (as defined in the Credit Agreement). The Existing Revolving Credit Facility is scheduled to mature in March 2026, and the Revolving Credit Facility is expected to mature in May 2029. There can be no assurance that the increase in the available capacity under, or the extension of the maturity of, the Revolving Credit Facility will occur. This offering is not contingent on the completion of any such transaction.

Certain of the underwriters or their affiliates are lenders under the Existing Revolving Credit Facility and, as a result of the intended use of net proceeds from this offering to repay outstanding borrowings under our Existing Revolving Credit Facility, certain of the underwriters or their affiliates may receive a portion of the net proceeds of this offering. See “Underwriting (Conflicts of Interest)—Conflicts of Interest.”

DESCRIPTION OF NOTES

The Issuer will issue the 20 Notes and the 20 Notes under supplemental indentures to be dated as of the closing date of the offering (collectively, the “supplemental indenture”) among LPL Holdings, Inc., as issuer, LPL Financial Holdings Inc., as guarantor, and U.S. Bank Trust Company, National Association, as trustee (the “trustee”), supplementing the indenture with the trustee dated as of November 17, 2023 (the “base indenture”). We refer to the base indenture, as supplemented by the supplemental indenture, as the “indenture.” The terms of the Notes include those expressly set forth in the indenture and those made a part of the indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

The following summary of the terms of the Notes and the indenture does not purport to be complete and is subject, and qualified in its entirety by reference, to the detailed provisions of the Notes and the indenture, including the definitions of certain terms used in the indenture. You may request a copy of the indenture from us as described under “Where You Can Find More Information” in the accompanying prospectus. Those documents, and not this description, define your legal rights as a holder of the Notes. The following description supplements, and supersedes to the extent it is inconsistent with, the statements under “Description of the Debt Securities and Guarantees” in the accompanying prospectus.

For purposes of this description, the terms the “Issuer” “we,” “us” and “our” refer only to LPL Holdings, Inc. and not to any of its subsidiaries, unless we specify otherwise. References to the “Guarantor” in this description refer to LPL Financial Holdings Inc., not including its subsidiaries. The Issuer is a direct subsidiary of the Guarantor and is an intermediate holding company of the Guarantor’s business.

General

The 20  Notes will be issued in an initial principal amount of $    million and will mature on  , 20 . The 20  Notes will be issued in an initial principal amount of $    million and will mature on  , 20 . We may, without the consent of holders of the Notes, increase the principal amount of the Notes of any series by issuing additional senior debt securities of such series in the future on the same terms and conditions, except for any difference in the issue price and interest accrued prior to the issue date of the additional senior debt securities of such series, and with the same CUSIP number as the Notes of such series offered hereby, provided that the additional senior debt securities of such series constitute part of the same issue as the Notes of the applicable series offered hereby for U.S. federal income tax purposes. The Notes of a series offered by this prospectus supplement and any additional senior debt securities of such series would rank equally and ratably and would be treated as a single series of debt securities for all purposes under the indenture.

The Notes of each series will be issued only in fully registered, book-entry form, in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, except under the limited circumstances described below under “—Certificated Securities”.

The indenture does not contain any provisions that would necessarily protect holders of the Notes if the Issuer or the Guarantor become involved in a highly leveraged transaction, change of control, reorganization, merger or other similar transaction that adversely affects the Issuer, the Guarantor or the holders of the Notes. A sinking fund will not be provided for the Notes.

Guarantee

The Guarantor will fully and unconditionally guarantee on a senior unsecured basis the due and punctual payment of the principal of, premium, if any, and interest on the Notes, and all other amounts due under the indenture, when and as the same shall become due and payable, whether at maturity, by acceleration, upon redemption or otherwise (the “guarantee”). The guarantee provides that in the event of a default in payment on a Note, the holder of the Note may institute legal proceedings directly against the Guarantor to enforce the guarantee without first proceeding against the Issuer.

S-25

Optional Redemption

Prior to    the applicable Par Call Date (as defined below), the Issuer may redeem the 20  Notes or the 20  Notes at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the applicable Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points in the case of the 20  Notes and    basis points in the case of the 20  Notes less (b) interest accrued to, but excluding, the redemption date, and

(2) 100% of the principal amount of the Notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after the applicable Par Call Date, the Issuer may redeem the 20  Notes or the 20  Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

“Par Call Date” means (i) with respect to the 20  Notes, at any time on or after   (  month(s) prior to the maturity date of the 20  Notes) and (ii) with respect to the 20  Notes, at any time on or after    (  month(s) prior to the maturity date of the 20  Notes).

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Issuer in accordance with the following two paragraphs.

The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the applicable Par Call Date, on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to the applicable Par Call Date. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date, and one with a maturity date following the applicable Par Call Date,

S-26

the Issuer shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Issuer’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any optional redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of the 20  Notes or the 20  Notes to be redeemed, as applicable.

In the case of a partial redemption, selection of the 20  Notes or the 20  Notes, as applicable, for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any 20  Note or 20  Note is to be redeemed in part only, the notice of redemption that relates to such Note will state the portion of the principal amount of the 20  Note or 20  Note to be redeemed. A new 20  Note or 20  Note, as applicable, in a principal amount equal to the unredeemed portion of the 20  Note or 20  Note, as applicable, will be issued in the name of the holder of the 20  Note or 20  Note, as applicable, upon surrender for cancellation of the original 20  Note or 20  Note, as applicable. For so long as the 20  Notes or 20  Notes, as applicable, are held by DTC (or another depositary), the redemption of the 20  Notes or 20  Notes, as applicable, shall be done in accordance with the policies and procedures of the depositary.

Unless the Issuer defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the 20  Notes, 20  Notes or portions thereof, as applicable, called for redemption.

In addition, the Issuer, the Guarantor and their respective affiliates may purchase the 20  Notes and 20  Notes from the holders thereof from time to time, either in the open market or in private transactions. Any of the 20  Notes and 20  Notes purchased by the Issuer, the Guarantor or any of their respective affiliates may, at the purchaser’s discretion, be held, resold or canceled.

Special Mandatory Redemption

If (i) the consummation of the Atria Acquisition (as defined below) does not occur on or before March 7, 2025, (ii) the Issuer notifies the trustee and the holders of the 20  Notes that the Issuer will not pursue the consummation of the Atria Acquisition or (iii) the Atria Agreement (as defined below) has been terminated without consummation of the Atria Acquisition (each of (i), (ii) and (iii), a “Special Mandatory Redemption Trigger”), we will be required to redeem the 20 Notes then outstanding (such redemption, the “Special Mandatory Redemption”) at a redemption price equal to 101% of the principal amount of the 20 Notes plus accrued and unpaid interest, if any, to but excluding the Special Mandatory Redemption Date (the “Special Mandatory Redemption Price”).

In the event that we become obligated to redeem the 20  Notes pursuant to the Special Mandatory Redemption, we will promptly, and in any event not more than ten business days after the date on which a Special Mandatory Redemption Trigger occurred, deliver notice to the trustee and the holders of the 20 Notes of the Special Mandatory Redemption and the date upon which the 20 Notes will be redeemed (the “Special

S-27

Mandatory Redemption Date”, which date shall be within ten business days following the date of such notice, unless some longer minimum period may be required by DTC (or any successor depositary), in which case the Special Mandatory Redemption Date will be the first business day following the end of such longer minimum period), together with a notice of Special Mandatory Redemption for the trustee to deliver to each registered holder of the 20 Notes. The trustee will then reasonably promptly mail or electronically deliver (or otherwise transmit in accordance with the depositary’s procedures) such notice of Special Mandatory Redemption to each registered holder of the 20  Notes. Unless the Issuer defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the 20  Notes.

Failure to make the Special Mandatory Redemption, if required in accordance with the terms described above, will constitute an event of default with respect to the 20  Notes.

Upon the consummation of the Atria Acquisition, the foregoing provisions regarding Special Mandatory Redemption will cease to apply. For the purposes of the foregoing, the Atria Acquisition will be deemed consummated if the closing under the Atria Agreement occurs, including after giving effect to any amendments or modifications to the Atria Agreement or waivers thereunder.

For purposes of the 20  Notes:

“Atria Acquisition” means the acquisition by the Issuer of Atria Wealth Solutions, Inc. pursuant to the Atria Agreement.

“Atria Agreement” means the Stock Purchase Agreement dated as of February 12, 2024 by and among Atria Wealth Solutions, Inc., Atria Wealth Solutions Holdings, LLC and the Issuer.

The 20  Notes will not be subject to the special mandatory redemption provisions described above.

Interest

Interest on the 20  Notes will accrue at the rate of   % per year from and including     , 2024 or the most recent interest payment date to which interest has been paid or provided for, and will be payable semi- annually in cash in arrears on     and    of each year, commencing on     , 2024. Interest will be paid to those persons who were holders of record of the 20  Notes on the immediately preceding and      . Interest on the 20  Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Interest on the 20  Notes will accrue at the rate of  % per year from and including    , 2024 or the most recent interest payment date to which interest has been paid or provided for, and will be payable semi- annually in cash in arrears on     and     of each year, commencing on    , 2024. Interest will be paid to those persons who were holders of record of the 20  Notes on the immediately preceding and    . Interest on the 20  Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

If any interest payment date or stated maturity date is not a business day, the payment otherwise required to be made on such date will be made on the next business day without any additional payment as a result of such delay. The term “business day” means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in the City of New York, New York are authorized or obligated by law or executive order to close or be closed. All payments will be made in U.S. dollars.

Priority

The Notes will be senior unsecured obligations of the Issuer that rank equally in right of payment with all of the Issuer’s other unsecured and unsubordinated indebtedness and that rank senior in right of payment to all of

S-28

the Issuer’s future subordinated debt. The Notes will be effectively subordinated to the Issuer’s existing and future secured obligations (including obligations under the Senior Secured Credit Facilities) to the extent of the value of the collateral securing such obligations and will be structurally subordinated to all of the existing and future liabilities of the Issuer’s subsidiaries. As of March 31, 2024, the Issuer’s subsidiaries had liabilities of $3,829.7 million (excluding intercompany liabilities).

As described under “—Guarantee,” the Notes will be fully and unconditionally guaranteed on a senior unsecured basis by the Guarantor. The guarantee will be a senior unsecured obligation of the Guarantor that ranks equally in right of payment with all of the Guarantor’s existing and future senior unsecured obligations that are not expressly subordinated to the guarantee. The guarantee will be effectively subordinated to the Guarantor’s future secured obligations to the extent of the value of the collateral securing such obligations and will be structurally subordinated to all of the existing and future liabilities of the Guarantor’s subsidiaries. The guarantee will be senior in right of payment to all of the Guarantor’s future subordinated debt.

Neither the Issuer nor the Guarantor has direct operations and each of the Issuer and the Guarantor derives all of its cash flow from its subsidiaries. Because each of the Issuer and the Guarantor conducts its operations through subsidiaries, such entity depends on its subsidiaries for dividends and other payments or distributions to meet any existing or future debt service and other obligations. Our subsidiaries will not have any obligation to pay amounts due on the Notes or to make funds available for that purpose. Each subsidiary is a distinct legal entity and, under certain circumstances, legal and contractual restrictions may limit our ability to obtain cash from our subsidiaries. The deterioration of the earnings from, or other available assets of, the Issuer’s and the Guarantor’s respective subsidiaries for any reason could limit or impair their ability to pay dividends or other distributions to the Issuer or the Guarantor. In addition, our broker-dealer subsidiaries are members of FINRA, and FINRA regulations restrict dividends in excess of 10% of a member firm’s excess net capital without FINRA’s prior approval. Compliance with this regulation may impede our ability to receive dividends from our broker-dealer subsidiaries.

The indenture does not limit the amount of additional indebtedness, including senior or secured indebtedness, which the Issuer or the Guarantor can create, incur, assume or guarantee, nor does the indenture limit the amount of indebtedness or other liabilities that our subsidiaries can create (other than the restrictions described in “—Limitation on Liens” below), incur, assume or guarantee. See “Risk Factors—Risks Related to our Indebtedness and the Notes”.

As of March 31, 2024, on an as adjusted basis after giving effect to the amount of borrowings we intend to repay under our Existing Revolving Credit Facility with a portion of the proceeds from this offering, additional borrowings and prepayments under the Existing Revolving Credit Facility after March 31, 2024 and the expected increase in the available capacity under the Revolving Credit Facility to $2,250.0 million, the Issuer’s aggregate outstanding debt would have been $    and the Issuer would have had $    of available capacity under the Revolving Credit Facility and the Issuer’s subsidiaries would have had $1,200.0 million or more available under LPL Financial’s five lines of credit and revolving credit facility, in each case, subject to compliance with certain conditions. Two of LPL Financial’s lines of credit have unspecified limits, both of which are primarily dependent on our ability to provide sufficient collateral, and three lines of credit and revolving credit facility have a total limit of $1,200.0 million. As of March 31, 2024, the Guarantor had no indebtedness other than its guarantees of indebtedness of the Issuer.

Maturity

The 20  Notes will mature on   , 20 , and the 20  Notes will mature on     , 20 .

Covenants

Limitation on Liens

Neither the Issuer nor the Guarantor will, and neither of them will permit any of their respective subsidiaries to, create, assume, incur or guarantee any indebtedness for borrowed money secured by a pledge, lien or other

S-29

encumbrance, except for Permitted Liens, on the voting securities of any Principal Subsidiary unless the Issuer or the Guarantor, as applicable, causes the Notes (and if the Issuer or the Guarantor, as applicable, so elects, any other indebtedness ranking on a parity with the Notes) to be secured equally and ratably with (or, at the option of the Issuer or the Guarantor, as applicable, prior to) any indebtedness for borrowed money secured thereby for so long as such indebtedness for borrowed money is so secured. For purposes of the Notes:

“Credit Agreement” means the Amended and Restated Credit Agreement, dated as of March 10, 2017, among the Issuer, the Guarantor, JPMorgan Chase Bank, N.A., as administrative agent and collateral agent, and the lenders and the other parties party thereto from time to time (as amended, amended and restated, extended, supplemented, refinanced, replaced or otherwise modified from time to time with borrowings or commitments from lenders under one or more credit agreements).

“Permitted Liens” means (1) liens for taxes or assessment or governmental charges or levies (a) that are not then due and delinquent or (b) the validity of which is being contested in good faith; (2) judgment liens arising from any litigation or legal proceedings which are currently being contested in good faith by appropriate proceedings; (3) deposits to secure (or in lieu of) surety, stay, appeal or customs bonds; (4) liens imposed by law, such as carriers’, warehousemen’s and mechanics’ liens and other similar liens arising in the ordinary course of business which secure payment of obligations not more than 60 days past due or which are being contested in good faith by appropriate proceedings and for which adequate reserves shall have been set aside on its books in accordance with GAAP; (5) liens arising out of pledges or deposits under worker’s compensation laws, unemployment insurance, old age pensions, or other social security or retirement benefits, or similar legislation; (6) any liens existing on the issue date (other than liens securing the Credit Agreement); (7) liens securing indebtedness for borrowed money under the Credit Agreement in an aggregate amount not to exceed $3,275,000,000; (8) any extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part, of any liens referred to in the foregoing clauses (3), (4), (5) and (6), provided that the principal amount of indebtedness for borrowed money secured thereby and not otherwise authorized as a Permitted Lien shall not exceed the principal of indebtedness for borrowed money, plus any premium or fee payable in connection with any such extension, renewal or replacement, so secured at the time of such extension, renewal or replacement; and (9) liens securing cash management and treasury services arising in the ordinary course of business.

“Principal Subsidiary” means any subsidiary of the Issuer or the Guarantor the total assets of which as set forth in the most recent statement of financial condition of such subsidiary equal more than 10% of the consolidated total assets of the Issuer or the Guarantor, as applicable, and their respective subsidiaries as determined from the most recent consolidated statement of financial condition of the Issuer or the Guarantor, as applicable, and their respective subsidiaries.

Notwithstanding the limitations on liens described, and without limiting the Issuer’s, the Guarantor’s or any of their respective subsidiaries’ ability to issue, incur, create, assume or guarantee indebtedness secured by Permitted Liens, the Issuer, the Guarantor and their respective subsidiaries will be permitted to incur indebtedness for borrowed money secured by a lien, without regard to the restrictions described in “—Limitations on Liens,” if at the time the indebtedness for borrowed money is incurred and after giving effect to such indebtedness for borrowed money and to the retirement of indebtedness which is concurrently being retired, the aggregate principal amount of all indebtedness for borrowed money secured by liens that are restricted by, and not otherwise permitted by, the provisions described under “—Limitation on Liens,” does not exceed 10% of the consolidated total assets of the Guarantor and its subsidiaries, as determined according to GAAP.

Additional Covenants

S-30

Merger, Consolidation and Sale of Assets

The indenture provides that the Issuer may not consolidate with or merge with or into, or convey, transfer or lease all or substantially all of its properties and assets to, another Person (in a transaction in which the Issuer is not the surviving entity) unless (1) the resulting, surviving or transferee Person is an entity organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and such Person expressly assumes by supplemental indenture all of the Issuer’s obligations under the Notes and the indenture; and (2) immediately after giving effect to such transaction, no event of default has occurred and is continuing under the indenture.

S-31

For purposes of the Notes:

“Person” means any individual, corporation, partnership, limited liability company, business trust, association, joint-stock company, joint venture, trust, incorporated or unincorporated organization or government or any agency or political subdivision thereof.

Events of Default, Notice and Waiver

The following are events of default under the indenture for the Notes of any series:

If an event of default with respect to Notes of any series, other than an event of default referred to in clause (7) above, occurs and is continuing, then and in every such case the trustee or the holders of not less than 25% in principal amount of the outstanding Notes of that series may declare the principal amount of all of the Notes of that series to be due and payable immediately, by a notice in writing to the Issuer (and to the trustee if given by holders of the Notes of that series), and upon any such declaration such principal amount (or specified amount)

S-32

shall become immediately due and payable. If an event of default specified in clause (7) above occurs, the principal amount of all of the outstanding Notes of that series shall be immediately due and payable without any declaration or other act on the part of the trustee or any holder of any Note of that series.

At any time after a declaration of acceleration with respect to the Notes of any series has been made and before a judgment or decree for payment of the money due has been obtained by the trustee as provided in the indenture, the holders of a majority in principal amount of the outstanding Notes of that series, by written notice to the Issuer and the trustee, may rescind and annul such declaration and its consequences if:

Except as provided in the indenture, the holders of not less than a majority in principal amount of the outstanding Notes of any series may on behalf of the holders of all the Notes of such series waive any past default under the indenture with respect to the Notes of such series and its consequences, except a default:

which default in the case of the foregoing clauses (1) and (2) may only be waived with the consent of the holder of each outstanding Note of such series affected thereby.

The Issuer will deliver to the trustee, within 120 days after the end of each fiscal year of the Issuer, an officer’s certificate stating whether or not, to the knowledge of the signing officer, the Issuer or the Guarantor was in default in the performance and observance of any of the terms, provisions and conditions applicable to the Issuer or the Guarantor during such fiscal year and, if the Issuer or the Guarantor was in default, specifying all such defaults and the nature and status thereof of which he or she may have knowledge. If any default or event of default under clauses (3) through (6) under “—Events of Default” has occurred and is continuing, within 30 business days after its becoming aware of such occurrence, the Issuer will deliver to the trustee an officer’s certificate specifying such event and what action the Issuer is taking or proposes to take with respect thereto.

Within 60 days after the trustee has actual knowledge of an occurrence of any default under the indenture with respect to the Notes of any series, the trustee must mail to each registered holder of the Notes of such series a notice of such default. However, except in the case of a default in the payment of the principal of (or premium, if any) or interest on any Note of such series, the trustee need not mail the notice if it in good faith determines that the withholding of such notice is in the interest of the holders of the Notes of such series.

Limitation on Suits

The indenture limits the right of holders of the Notes of any series to institute legal proceedings. No holder of the Notes of any series will have any right to institute any proceeding, judicial or otherwise, with respect to the indenture, or for the appointment of a receiver or trustee, or for any other remedy under the indenture, unless:

S-33

Subject to the indenture, applicable law and the trustee’s rights to indemnification, the holders of a majority in principal amount of the outstanding Notes of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the Notes of such series.

Legal Defeasance and Covenant Defeasance

The Issuer and the Guarantor may at any time elect to have all of their obligations discharged with respect to the outstanding Notes of any series and the guarantee of the outstanding Notes of such series on the date the certain conditions are satisfied (“legal defeasance”), except for the rights of holders of outstanding Notes of such series to receive payments in respect of the principal of (and premium, if any) and interest on the Notes of such series when such payments are due from the trust referred to below, and except for certain other obligations of the Issuer, certain other rights of the trustee under the indenture and the provision of the indenture relating to legal defeasance and covenant defeasance (as defined below).

In addition, the Issuer and the Guarantor may at any time elect to have their obligations released with respect to certain covenants and thereafter any omission to comply with those covenants will not constitute a default or event of default with respect to the Notes of a series (“covenant defeasance”). In the event covenant defeasance occurs, certain events will no longer constitute an event of default with respect to the Notes of such series.

In order to exercise either legal defeasance or covenant defeasance, the Issuer must irrevocably deposit with the trustee for the benefit of the holders of the Notes of the applicable series money or specified U.S. government obligations in amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay and discharge (i) the principal of (and premium, if any) and each installment of principal of (and premium, if any) and interest on the outstanding Notes of such series on the stated maturity of such principal or installment of principal or interest and (ii) any mandatory sinking fund payments or analogous payments applicable to the outstanding Notes of such series on the date on which such payments are due and payable in accordance with the terms of the indenture. In addition, the Issuer must deliver to the trustee certain opinions of counsel and an officer’s certificate in connection with such defeasance, and the Issuer may not exercise such defeasance (i) if an event of default with respect to the Notes of such series has occurred and is continuing on the date of such deposit (other than an event of default resulting from borrowing of funds to be applied to such deposit, the grant of any lien securing such borrowing and the consummation of other transactions in connection therewith), (ii) if such defeasance would cause the trustee for Notes of such series to have a conflicting interest for purposes of the Trust Indenture Act with respect to any securities of the Issuer or (iii) if such defeasance would result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Issuer or the Guarantor is a party or by which it is bound (other than an event of default resulting from borrowing of funds to be applied to such deposit, the grant of any lien securing such borrowing and the consummation of other transactions in connection therewith).

Satisfaction and Discharge

Upon the request of the Issuer, the indenture will cease to be of further effect with respect to the Notes of any series and the guarantee of Notes of such series (except as to any surviving rights of registration of transfer

S-34

or exchange of the Notes of such series and replacement of lost, stolen or mutilated Notes of such series provided for in the indenture), and the trustee, on the demand of and at the expense of the Issuer, will execute instruments acknowledging satisfaction and discharge of the indenture with respect to the Notes of such series, when:

and the Issuer, in the case of clauses (i), (ii) or (iii) above, has deposited or caused to be deposited with the trustee as trust funds in trust for the purpose of establishing an amount sufficient to pay and discharge the entire indebtedness on the Notes of such series delivered to the trustee for cancellation, for principal and interest to the date of such deposit (in the case of Notes of such series that have become due and payable) or to the stated maturity or redemption date, as the case may be,

At any time when no Notes of any series are outstanding, the indenture shall, upon request of the Issuer, cease to be of further effect and the trustee, at the expense of the Issuer, must execute instruments of satisfaction and discharge of the indenture.

Notwithstanding the satisfaction and discharge of the indenture, the obligations of the Issuer to the trustee under the section of the indenture relating to compensation and reimbursement of the trustee and, if the Issuer has deposited money with the trustee to pay and discharge the entire indebtedness on the Notes, the obligations of the trustee under the indenture relating to deposited money held in trust and money for Notes payments held in trust shall survive.

Modifications and Amendments

With the consent of the holders of not less than a majority in principal amount of the outstanding Notes of each series so affected by such supplemental indenture, by the action of such holders delivered to the Issuer and the trustee, the Issuer, any Guarantor affected thereby and the trustee (at the direction of the Issuer) may enter into an indenture or supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture or of the Notes of such series or of modifying in any manner the rights of the holders of the Notes of such series under the indenture. However, without the consent of the holder of each outstanding Note directly and adversely affected by a supplemental indenture, such supplemental indenture may not (with respect to any outstanding Notes held by a non-consenting holder):

S-35

Without the consent of or notice to any holders of the Notes or any other party hereto, the Issuer, the Guarantor and the trustee (at the direction of the Issuer) at any time and from time to time, may enter into one or more supplemental indentures for any of the following purposes:

S-36

Trustee

The trustee for the Notes is U.S. Bank Trust Company, National Association. We have appointed the trustee as the paying agent, and registrar with regard to the Notes. The indenture permits the trustee to deal with the Issuer, the Guarantor and any of their respective affiliates with the same rights the trustee would have if it were not trustee. However, under the Trust Indenture Act, if the trustee acquires any conflicting interest and there exists a default with respect to the Notes, the trustee must eliminate the conflict or resign. The trustee and its affiliates have in the past provided or may from time to time in the future provide banking and other services to us in the ordinary course of their business.

The holders of a majority in aggregate principal amount of the Notes of any series then outstanding have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, subject to certain exceptions. If an event of default occurs and is continuing, the trustee must exercise its rights and powers under the indenture and use the same degree of care and skill as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. The indenture does not obligate the trustee to exercise any of its rights or powers at the request or demand of the holders, unless the holders have offered to the trustee security and/or indemnity that is satisfactory to the trustee against the costs, expenses and liabilities which might be incurred by the trustee in compliance with such request or direction.

Denominations, Interest, Registration and Transfer

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 global securities. We will not impose a service

S-37

charge in connection with any transfer or exchange of any Note. See “—Global Notes; Book-Entry Form” for a description of transfer restrictions that apply to the Notes.

Global Notes; Book-Entry Form

Global notes will be deposited with the trustee as custodian for The Depository Trust Company (“DTC”) and registered in the name of DTC or a nominee of DTC.

Beneficial interests in a global note may be held directly through DTC if the holder is a participant in DTC or indirectly through organizations that are participants in DTC.

Except in the limited circumstances described below and in “—Certificated Securities,” holders of Notes will not be entitled to receive Notes in certificated form. Unless and until it is exchanged in whole or in part for certificated securities, each global note may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC.

We will apply to DTC for acceptance of the global securities in its book-entry settlement system. The custodian and DTC will electronically record the principal amount of Notes represented by global securities held within DTC. Beneficial interests in the global securities will be shown on records maintained by DTC and its direct and indirect participants, including Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), and Clearstream Banking, société anonyme (“Clearstream”). Investors may elect to hold interests in the global notes through either DTC in the U.S. or Clearstream or Euroclear in Europe if they are participants of such systems, or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of DTC. 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. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. These limitations and requirements may impair the ability to transfer or pledge beneficial interests in a global note.

Payments of principal, premium, if any, and interest under each global note will be made to DTC or its nominee as the registered owner of such global note. We expect that DTC or its 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. We also expect 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 us, 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.

DTC has advised us that it is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered under the Exchange Act. DTC was created to hold the securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, which eliminates the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers (including the

S-38

underwriters), banks, trust companies, clearing corporations and certain other organizations, some of whom (and/ or their representatives) own the depository. Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The ownership interest and transfer of ownership interests of each beneficial owner or purchaser of each security held by or on behalf of DTC are recorded on the records of the direct and indirect participants.

Clearstream advises that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book- entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides to Clearstream Participants, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a registered bank in Luxembourg, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector (Commission de Surveillance du Secteur Financier). Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant, either directly or indirectly.

Distributions with respect to interests in the Notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures.

Euroclear advises that it was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

Securities clearance accounts and cash accounts with the Euroclear Operator are governed by the Terms and Conditions Governing Use of Euroclear and the related Operating Procedures of Euroclear, and applicable Belgian law (collectively, the “Terms and Conditions”). The Terms and Conditions govern transfers of securities and cash within Euroclear, withdrawals of securities and cash from Euroclear, and receipts of payments with respect to securities in Euroclear. All securities in Euroclear are held on a fungible basis without attribution of specific certificates to specific securities clearance accounts. The Euroclear Operator acts under the Terms and Conditions only on behalf of Euroclear Participants, and has no records of or relationship with persons holding through Euroclear Participants.

Distributions with respect to the Notes held beneficially through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the Terms and Conditions.

The information in this section concerning DTC, DTC’s book-entry system, Clearstream and Euroclear has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

Neither we nor the trustee will be liable or responsible for DTC, Euroclear or Clearstream.

S-39

Certificated Securities

The trustee will exchange beneficial interests in a global note for one or more certificated securities registered in the name of the owner of the beneficial interest, as identified by DTC, only if:

Settlement and Payment

We will make payments in respect of Notes represented by global securities by wire transfer of immediately available funds to DTC or its nominee as registered owner of the global securities.

We expect the Notes will trade in DTC’s Same-Day Funds Settlement System, and DTC will require all permitted secondary market trading activity in the Notes to be settled in immediately available funds. We expect that secondary trading in any certificated securities will also be settled in immediately available funds.

Transfers between participants in DTC will be effected in the ordinary way in accordance with DTC rules and will be settled in same-day funds.

Although DTC has agreed to the above procedures to facilitate transfers of interests in the global securities among DTC participants, DTC is under no obligation to perform or to continue those procedures, and those procedures may be discontinued at any time. None of us, the underwriters or the trustee will have any responsibility for the performance by DTC or its direct or indirect participants of their respective obligations under the rules and procedures governing their operations.

Governing Law

The indenture and the Notes will be governed by and construed in accordance with the laws of the State of New York.

S-40

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain U.S. federal income tax consequences applicable to the ownership and disposition of the Notes issued in this offering but does not purport to be a complete analysis of all potential U.S. federal income tax consequences. This summary is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations promulgated thereunder, Internal Revenue Service (“IRS”) rulings and judicial decisions, each as in effect or in existence as of the date of this prospectus supplement. All of these are subject to change or different interpretations, possibly with retroactive effect, which may result in U.S. federal income tax consequences different from those summarized below. No ruling has been requested from the IRS regarding the considerations discussed in this summary, and there is no assurance that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax considerations discussed below.

This summary does not address all aspects of U.S. federal income taxation that may be relevant to particular investors in the Notes in light of their specific circumstances or to investors that may be subject to special rules under U.S. federal income tax law, including:

This summary also does not discuss alternative minimum tax consequences or the tax consequences arising under any state, local or non-U.S. law, or any U.S. federal tax consequences other than U.S. federal income tax consequences (such as estate or gift tax consequences or the 3.8% Medicare tax on certain investment income).

This discussion is limited to investors who purchase Notes for cash in this offering. Moreover, this discussion is limited to investors who purchase and hold Notes as “capital assets” within the meaning of Section 1221 of the Code.

S-41

For purposes of this summary, “U.S. Holder” means the beneficial owner of a Note that is, or that for U.S. federal income tax purposes is treated as:

For purposes of this summary, the term “Non-U.S. Holder” means any beneficial owner of a Note that is, for U.S. federal income tax purposes, an individual, a corporation, a trust or an estate that is not a U.S. Holder.

If any entity or arrangement treated as a partnership for U.S. federal income tax purposes holds the Notes, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. If you are a partnership or a partner in a partnership, you should consult your own tax advisor as to the tax consequences of the partnership’s purchase, ownership and disposition of the Notes.

THE FOLLOWING DISCUSSION IS INTENDED FOR INFORMATIONAL PURPOSES ONLY AND IS NOT A SUBSTITUTE FOR CAREFUL TAX PLANNING AND ADVICE. PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH REGARD TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX CONSEQUENCES DESCRIBED BELOW TO THEIR PARTICULAR SITUATIONS, AS WELL AS THE APPLICATION OF ANY STATE, LOCAL, NON-U.S. OR OTHER U.S. FEDERAL TAX LAWS, INCLUDING GIFT AND ESTATE TAX LAWS AND THE MEDICARE TAX ON INVESTMENT INCOME.

Effect of Certain Additional Payments

In certain circumstances, we may pay amounts in excess of the stated interest or principal on the Notes or to make payments in advance of their scheduled times (e.g., as described under “Description of Notes—Optional Redemption” and, with respect to the 20 Notes, as described under “Description of Notes—Special Mandatory Redemption”). Except as otherwise provided, we do not intend to take such potential payments into account in determining the yield to maturity of the Notes because of, among other things, the likelihood of such payments. This position is based in part on assumptions, as of the date of issuance of the Notes, (1) regarding the likelihood that such payments will have to be paid or that we will elect to pay such amounts and/or (2) relating to the expected yield to maturity of the Notes. Our position is binding on a holder subject to U.S. federal income taxation unless such investor discloses its contrary position in the manner required by applicable U.S. Treasury regulations. Our position is not, however, binding on the IRS, and, if the IRS were to successfully challenge this position, an investor might be required to accrue ordinary interest income on the Notes in an amount greater than, and with timing different from the timing described herein, with respect to the stated interest and to treat as ordinary interest income (rather than capital gain) any gain realized on a taxable disposition of a Note.

The remainder of this discussion assumes that the Notes will not be treated as contingent payment debt instruments. Prospective investors should consult their own tax advisors regarding the tax considerations relating to contingent payment debt instruments.

S-42

Taxation of U.S. Holders

Stated Interest

Stated interest on a Note generally will be taxable to a U.S. Holder as ordinary interest income at the time such amounts are accrued or received, in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.

Possible effect of certain alterations to the Notes or transactions including reorganizations, mergers and consolidations

The Issuer may make certain alterations to the Notes or engage in certain transactions, including without limitation reorganizations, mergers and consolidations as described above under “Description of Notes.” Depending on the circumstances, a change in the obligor of the Notes as a result of such alteration or transaction could result in a deemed taxable exchange to a U.S. Holder and the modified Note could be treated as newly issued at that time, potentially resulting in the recognition of taxable gain or loss. The Issuer may be required to report certain information regarding such transaction that may be relevant to U.S. Holders including by (1) filing Form 8937 with the IRS and providing copies to certain of its Holders or (2) posting such information on its website.

Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of a Note

A U.S. Holder generally will recognize gain or loss upon a sale, exchange, retirement, redemption or other taxable disposition of a Note, equal to the difference, if any, between:

A U.S. Holder’s adjusted tax basis in a Note will generally equal the cost of the Note to such U.S. Holder, reduced (but not below zero) by any prior principal payments on such Note.

Any such gain or loss generally will be capital gain or loss and generally will be long-term capital gain or loss if the Note has been held for more than one year by the U.S. Holder at the time of the disposition. Under current law, long-term capital gains of non-corporate U.S. Holders, including individuals, may be taxed at preferential rates. The ability of a U.S. Holder to offset capital losses against ordinary income is subject to limitations.

Information Reporting and Backup Withholding

Information reporting requirements generally will apply with respect to payments of stated interest and the proceeds from a sale or other taxable disposition (including a retirement or redemption) of the Notes, unless a U.S. Holder is an exempt recipient. In addition, backup withholding may apply to such payments and proceeds if a U.S. Holder fails to properly establish an exemption (generally, by providing an IRS Form W-9 certifying such exemption). All individuals are subject to these requirements. In general, corporations are exempt from these requirements; provided that their exemptions are properly established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be credited against a U.S. Holder’s U.S. federal income tax liability (or refunded); provided that the required information is timely provided to the IRS. U.S. Holders should consult their own tax advisors regarding the application of backup withholding in their particular situation, the availability of an exemption from backup withholding and the procedure for obtaining such an exemption, if available.

S-43

Taxation of Non-U.S. Holders

The rules governing the U.S. federal income taxation of Non-U.S. Holders are complex. Non-U.S. Holders should consult their own tax advisors to determine the effect of U.S. federal, state, local and non-U.S. income tax laws, as well as treaties, with regard to an investment in the Notes, including any reporting requirements.

Interest

Subject to the discussion below regarding backup withholding and FATCA (as defined below), no U.S. federal income or withholding tax generally will be required with respect to the payment of interest on the Notes that qualifies as portfolio interest. Interest on a Note owned by a Non-U.S. Holder will qualify as portfolio interest if (1) such interest is not effectively connected with the conduct of a U.S. trade or business by such Non-U.S. Holder, (2) such Non-U.S. Holder does not actually or constructively own stock processing 10% or more of the total combined voting power of all classes of our stock entitled to vote within the meaning of the Code and applicable U.S. Treasury regulations, (3) such Non-U.S. Holder is not a controlled foreign corporation that is related to us actually or constructively (within the meaning of the Code and applicable U.S. Treasury regulations), (4) such Non-U.S. Holder is not a bank whose receipt of interest on the Notes is described in Section 881(c)(3)(A) of the Code, and (5) the applicable certification requirements (including a certification that such Non-U.S. Holder is not a U.S. person) are satisfied (generally by providing a properly completed IRS Form W-8BEN or IRS Form W-8BEN-E (or successor form or other applicable form)).

If a Non-U.S. Holder cannot satisfy the requirements described above, payments of interest will be subject to a 30% U.S. federal withholding tax unless, under current procedures, the Non-U.S. Holder delivers (i) a properly completed IRS Form W-8ECI (or successor form) stating that interest paid on its Notes is not subject to withholding tax because it is effectively connected to its conduct of a trade or business in the United States (in which case such interest will be subject to tax as discussed below) or (ii) a properly completed IRS Form W-8BEN or W-8BEN-E (or successor form) claiming an exemption from or reduction in withholding tax under an applicable income tax treaty.

Interest that is effectively connected with the conduct of a U.S. trade or business of a Non-U.S. Holder generally will not be subject to withholding tax, but will be taxable on a net basis as if the Non-U.S. Holder were a U.S. Holder (unless an applicable income tax treaty provides otherwise). Moreover, a Non-U.S. Holder that is a corporation may be subject to an additional 30% branch profits tax (or a lower applicable treaty rate) on such Non-U.S. Holder’s effectively connected earnings and profits, subject to adjustments.

Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of a Note

Subject to the discussion below regarding backup withholding and FATCA, a Non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax on any gain realized on the sale, exchange, retirement, redemption or other disposition of a Note (except to the extent proceeds are attributable to accrued but unpaid stated interest, in which case the above rules regarding interest would apply), unless (1) such gain is effectively connected with the conduct by the Non-U.S. Holder of a trade or business in the United States, in which case (unless an applicable income tax treaty provides otherwise) the Non-U.S. Holder generally will be taxed in the same manner discussed above with respect to effectively connected interest income (and, in the case of a Non-U.S. Holder that is a corporation, may also be subject to the branch profits tax); or (2) in the case of a Non-U.S. Holder that is an individual, the holder is present in the United States for 183 days or more in the taxable year of the disposition and certain other conditions are met, in which case the Non-U.S. Holder will be subject to a flat 30% U.S. federal income tax on the amount by which capital gains allocable to U.S. sources (including gains from a taxable disposition of the note) exceed certain capital losses allocable to U.S. sources (except as otherwise provided by an applicable income tax treaty).

S-44

Possible effect of certain alterations to the Notes or transactions including reorganizations, mergers and consolidations

As described in more detail under “Taxation of U.S. Holders—Possible effect of certain alterations to the Notes or transactions including reorganizations, mergers and consolidations,” the Issuer may make certain alterations to the Notes or engage in certain transactions that could result in deemed taxable exchange of the Notes.

Information Reporting and Backup Withholding

Generally, we must report to the IRS and to a Non-U.S. Holder the amount of interest paid to the Non-U.S. Holder and the amount of tax, if any, withheld with respect to those payments. Under the provisions of an applicable income tax treaty or agreement, copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which the Non-U.S. Holder resides.

In general, a Non-U.S. Holder will not be subject to backup withholding with respect to payments of interest on the Notes; provided that the Non-U.S. Holder has provided certification that such holder is a Non-U.S. Holder (generally by providing a properly completed applicable IRS Form W-8).

Information reporting and, depending on the circumstances, backup withholding, will generally apply to the proceeds of a sale or other disposition (including a retirement or redemption) of the Notes within the United States or conducted through certain U.S.-related financial intermediaries, unless the Non-U.S. Holder certifies to the payor under penalties of perjury that such holder is not a U.S. person or otherwise establishes an exemption. Under current law, the backup withholding rate is 24%.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be credited against a Non-U.S. Holder’s U.S. federal income tax liability, if any (or refunded); provided that the required information is timely provided to the IRS. Non-U.S. Holders should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situation, the availability of an exemption from backup withholding and the procedure for obtaining such an exemption, if available.

FATCA

Pursuant to Sections 1471 through 1474 of the Code (commonly referred to as “FATCA”), U.S. Treasury regulations thereunder, and administrative guidance, a 30% U.S. federal withholding tax will apply to payments of interest on the Notes paid to (i) a foreign financial institution (whether such foreign financial institution is the beneficial owner or an intermediary) unless such institution enters into an agreement with the U.S. government to collect and report to the U.S. government, on an annual basis, information with respect to its U.S. accountholders and meets certain other specified requirements (or, in certain circumstances, complies with similar reporting requirements of the non-U.S. government in the jurisdiction in which it is organized or located under an intergovernmental agreement between such non-U.S. government and the U.S. government) or (ii) a non-financial foreign entity (whether such non-financial foreign entity is the beneficial owner or an intermediary) unless such entity certifies that it does not have any “substantial United States owners” or provides certain information regarding the entity’s “substantial United States owners” and such entity meets certain other specified requirements. FATCA generally will apply to all such payments without regard to whether the beneficial owner of the payment is a U.S. person or would otherwise be entitled to an exemption from imposition of the U.S. federal withholding tax discussed above under “Taxation of Non-U.S. Holders” pursuant to an applicable tax treaty with the United States or pursuant to U.S. domestic law. Prospective investors should consult their own tax advisors regarding the possible implications of FATCA and whether it may be relevant to such investor’s acquisition, ownership and disposition of the Notes.

S-45

CERTAIN ERISA CONSIDERATIONS

The following is a summary of certain considerations associated with the purchase, holding, and disposition of the Notes by (i) any employee benefit plan (as defined in Section 3(3) of ERISA) that is subject to Title I of ERISA, (ii) any plan (as defined in Section 4975(e)(1) of the Code), to which Section 4975 of the Code applies, or (iii) any entity the underlying assets of which are considered to include “plan assets” of any plans described in subsections (i) or (ii) (as determined pursuant to U.S. Department of Labor regulations at 29 CFR 2510.3-101, as modified by Section 3(42) of ERISA) (collectively, the plans and entities described in subsections (i) through (iii) above are referred to herein as “Plans”). Plans that are governmental plans (as defined in Section 3(32) of ERISA), certain church plans (as defined in Section 3(33) of ERISA) or other employee benefit plans or arrangements not subject to Title I of ERISA or Section 4975 of the Code (“Other Plan Investors”) may not be subject to the fiduciary responsibility or prohibited transaction provisions of ERISA or the Code but may be subject to similar restrictions under Similar Laws.

General Fiduciary Matters

ERISA and Section 4975 of the Code impose certain duties on persons who are fiduciaries of a Plan and prohibit certain transactions involving the assets of a Plan and its fiduciaries or other interested parties. Under ERISA and Section 4975 of the Code, any person who exercises any discretionary authority or control over the administration of a Plan or the management or disposition of the assets of such a Plan, or who renders investment advice for a fee or other compensation to such a Plan, is generally considered to be a fiduciary of the Plan.

Section 404(a)(1) of ERISA sets forth a general standard of behavior and restrictions for fiduciaries of Plans subject to Title I of ERISA. It requires that a fiduciary discharge its duties with respect to such a Plan (i) solely in the interest of the participants and beneficiaries of such Plan, (ii) for the exclusive purpose of providing benefits to participants and their beneficiaries and defraying reasonable expenses of administering the Plan, (iii) in accordance with a prudent-man rule (that is “with the care, skill, prudence and diligence under the circumstances then prevailing that a prudent man acting in a like capacity and familiar with such matters would use in the conduct of an enterprise of a like character and with like aims”), (iv) by diversifying the investments of the Plan so as to minimize the risk of large losses, unless under the circumstances it is clearly prudent not to do so, and (v) in accordance with the documents governing the Plan insofar as they are consistent with ERISA.

In considering an investment in the Notes with the assets of any such Plan, a fiduciary should give appropriate consideration to, among other things, whether the acquisition and holding of the Notes is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, Section 4975 of the Code or any Similar Laws relating to the fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA and Section 4975 of the Code, the role that the investment plays in the Plan’s portfolio, taking into consideration whether the investment is designed reasonably to further the Plan’s purposes, an examination of the risk and return factors, the portfolio’s composition with regard to diversification, the liquidity and current return of the total portfolio relative to the anticipated cash flow needs of the Plan, and the projected return of the total portfolio relative to the Plan’s funding objectives. Similar duties and restrictions may apply to fiduciaries of Other Plan Investors. Fiduciaries of Other Plan Investors subject to Similar Laws should consider their fiduciary duties under such Similar Laws in determining whether to invest in the Notes offered hereby.

Prohibited Transaction Issues

Section 406 of ERISA and Section 4975 of the Code prohibit Plans from engaging in specified transactions involving assets of a Plan with persons or entities who are “parties in interest” within the meaning of Section 3(14) of ERISA or “disqualified persons” within the meaning of Section 4975 of the Code, unless a statutory or administrative exemption is applicable to the transaction. “Parties in interest” or “disqualified persons” could include, without limitation, us, the underwriters, the agents or any of their respective affiliates.

S-46

“Prohibited transactions” may include, without limitation, (1) a direct or indirect extension of credit to a party in interest or to a disqualified person, (2) the sale or exchange of any property (such as the Notes) between a Plan and a party in interest or a disqualified person, or (3) the transfer to, or use by or for the benefit of, a party in interest or a disqualified person, of any plan assets. The acquisition and/or holding of the Notes by a Plan with respect to which we, any of our affiliates, the trustee or any of its respective affiliates or any underwriter is or becomes considered a party in interest or a disqualified person may constitute or result in a direct or indirect prohibited transaction under Section 406 of ERISA and/or Section 4975 of the Code, unless the Notes are acquired and are held in accordance with an applicable statutory, class or individual prohibited transaction exemption. Relevant class exemptions may include, without limitation, PTCE 84-14 (respecting transactions determined by independent qualified professional asset managers), PTCE 90-1 (respecting transactions involving insurance company pooled separate accounts), PTCE 91-38 (respecting transactions involving bank collective investment funds), PTCE 95-60 (respecting transactions involving life insurance company general accounts) and PTCE 96-23 (respecting transactions determined by in-house asset managers). In addition, the statutory exemption under Section 408(b)(17) of ERISA and Section 4975(d)(20) of the Code provides relief from the prohibited transaction provisions of ERISA and Section 4975 of the Code for certain transactions between a Plan and a person that is a party in interest or disqualified person; provided that such person is a party in interest or disqualified person solely by reason of providing services to the Plan or a relationship to such a service provider, and neither such person nor any of its affiliates (directly or indirectly) has or exercises any discretionary authority or control or renders any investment advice with respect to the assets of the Plan involved in the transaction; provided further that the Plan pays no more than and receives no less than adequate consideration in connection with the transaction. There can be no assurance that all of the conditions of any such exemptions will be satisfied, and prospective acquirers of the Notes should consult with their legal advisors regarding the applicability of any such exemptions. Furthermore, note that these exemptions may be subject to change from time to time, including, for example, PTCE 84-14, with respect to which the U.S. Department of Labor has recently published a final amendment.

A party in interest or disqualified person who engages in a non-exempt prohibited transaction (including, without limitation, the lending of money or the extension of credit by the Plan) may be subject to excise taxes and other penalties and liabilities under ERISA and the Code. For example, a Plan holding a Note would be viewed by the U.S. Department of Labor as a continuing extension of credit by the Plan to the Company. In addition, a fiduciary of a Plan that engages in such a non-exempt prohibited transaction may be subject to penalties and liabilities under ERISA and the Code, including an obligation to correct the transaction. Each original or subsequent purchaser or transferee of a Note that is or may become a Plan is responsible for determining the extent, if any, to which the purchase and holding of a Note will constitute a prohibited transaction under ERISA or Section 4975 of the Code.

Because of the foregoing, the Notes should not be purchased or held by any person investing “plan assets” of any Plan unless such purchase, holding and, if applicable, disposition will not constitute a non-exempt prohibited transaction under ERISA or the Code or a violation of any applicable Similar Laws.

Representation

The foregoing discussion is general in nature and is not intended to be all-inclusive. Further, no assurance can be given that future legislation, administrative rulings, court decisions or regulatory action will not modify the conclusions set forth in this discussion. Any such changes may be retroactive and thereby apply to transactions entered into prior to the date of their enactment or release. Due to the complexity of these rules and the penalties that may be imposed upon persons involved in non-exempt prohibited transactions, it is particularly important that Plan fiduciaries, or other persons considering acquiring the Notes (and holding the Notes) on behalf of, or with the assets of, any Plan, consult with their counsel, prior to any such acquisition, regarding the potential applicability of ERISA, Section 4975 of the Code and any Similar Laws to such investment and whether an exemption would be applicable to the acquisition and holding of the Notes.

S-47

Nothing herein shall be construed as a representation that an investment in the Notes would meet any or all of the relevant legal requirements with respect to investments by, or is appropriate for, a Plan. Purchasers of the Notes have the exclusive responsibility for ensuring that their acquisition, holding, and disposition of the Notes complies with their fiduciary duties set forth in ERISA, the Code and any applicable Similar Laws and does not violate the prohibited transaction rules of ERISA or the Code or provisions under any applicable Similar Laws. No representation is made that the sale of any Notes to a Plan meets the fiduciary requirements for investments by Plans generally or any particular Plan or that such an investment is appropriate for Plans generally. Neither we nor any of the parties described in this prospectus supplement, or their affiliates, are providing investment advice to any Plan, through this prospectus supplement or otherwise, in connection with the sale of the Notes.

Each person acquiring a Note will be deemed to have represented and agreed that either (i) it is not a Plan or an Other Plan Investor and no assets of a Plan or an Other Plan Investor have been used to acquire the Notes or (ii) (A) its acquisition, holding and disposition of the Notes or interests in the Notes will not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA or Section 4975 of the Code (or, in the case of an Other Plan Investor, a violation of any Similar Laws), (B) none of the Issuer, the underwriters or any of their respective affiliates have undertaken or will undertake to provide impartial investment advice, or has given or will give advice in a fiduciary capacity in connection with the Notes and the transactions contemplated with respect to the Notes and (C) the decision to purchase the Notes has been made by a duly authorized fiduciary who is independent of the issuer, the underwriters and their respective affiliates.

UNDERWRITING (CONFLICTS OF INTEREST)

J.P. Morgan Securities LLC, Citigroup Global Markets Inc., Citizens JMP Securities, LLC, Truist Securities, Inc. and U.S. Bancorp Investments, Inc. are acting as joint book-running managers of this offering and as representatives of the underwriters named below. Subject to the terms and conditions contained in an underwriting agreement dated the date of this prospectus supplement, among the Issuer, the Guarantor and the representatives of the underwriters, each underwriter named below, with respect to the sale of the applicable series of Notes, has severally, and not jointly, agreed to purchase, and the Issuer has agreed to sell to that underwriter, the principal amount of Notes set forth opposite the underwriter’s name.

The underwriting agreement provides that the underwriters are obligated to purchase all the Notes, if any are purchased.

The underwriters are offering the Notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the Notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and customary legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to investors and to reject orders in whole or in part.

The following table shows the per note and total underwriting discount to be paid to the underwriters by us in connection with this offering:

The Notes sold by the underwriters to the public will initially be offered at the applicable public offering price listed on the cover page of this prospectus supplement. Any 20  Notes sold by the underwriters to dealers may be sold at such price less a concession not in excess of  % of the principal amount of the 20  Notes. The underwriters may allow, and dealers may re-allow, a concession not in excess of  % of the principal amount of the 20  Notes, to other dealers. Any 20  Notes sold by the underwriters to dealers may be sold at such price less a concession not in excess of  % of the principal amount of the 20  Notes. The underwriters may allow, and dealers may re-allow, a concession not in excess of  % of the principal amount of the 20  Notes, to other dealers. After the initial offering, the public offering price, concession or any other term of this offering may be changed.

We estimate that the total expenses of this offering, including printing fees and legal and accounting expenses, but excluding registration and filing fees and the underwriting discounts will be approximately $   .

We have also agreed to indemnify and hold harmless the several underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”), or to contribute to payments the underwriters may be required to make in respect of those liabilities.

S-49

During the period from the date hereof through and including the closing date of this offering, the Issuer and the Guarantor have agreed to not, without the prior written consent of the representatives of the underwriters, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Issuer or the Guarantor and having a tenor of more than one year.

New Issue of Notes

The 20  Notes and the 20  Notes are new issues of securities with no established trading markets. We do not intend to apply for the Notes of any series to be listed on any national securities exchange or to arrange for their quotation on any automated dealer quotation system. We cannot assure you that the prices at which the Notes of any series will sell in the market after this offering will not be lower than the initial offering price or that an active trading market for the Notes of any series will develop and continue after this offering. Certain of the underwriters have advised us that they currently intend to make a market in the Notes of each series. However, they are not obligated to do so, and they may discontinue any market making activities with respect to the Notes of any series at any time without notice. In addition, market making activity will be subject to the limits imposed by the Securities Act and the Exchange Act. Accordingly, we cannot assure you as to the liquidity of, or the trading market for, the Notes of any series.

Price Stabilization and Short Positions

In connection with this offering, the underwriters may purchase and sell Notes in the open market. These transactions may include over-allotment, stabilizing transactions and covering transactions. Over-allotment involves sales in excess of the principal amount of the Notes the underwriters are obligated to purchase, which creates a short position for the underwriter. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Covering transactions involve purchases of the Notes in the open market after the distribution has been completed in order to cover short positions. These transactions may be effected in the over-the-counter market or otherwise.

These activities may stabilize, maintain or otherwise affect the market price of the Notes of any series. As a result, the price of the Notes of any series may be higher than the price that otherwise might exist in the open market. Neither the underwriters nor we make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Notes of any series. In addition, there is no obligation on the part of the underwriters to engage in such transactions and neither the underwriters nor we make any representation that any underwriter will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Initial Settlement

We expect to deliver the Notes against payment for the Notes 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 (this settlement cycle being referred to as “T+5”). Pursuant to Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on any date prior to two business days before delivery will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Notes should consult their own advisors.

Other Relationships

The underwriters and certain of their affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, lending, financing and brokerage

S-50

activities. The underwriters and certain of their affiliates have, from time to time, performed, and may in the future perform, various commercial and investment banking and financial advisory services for LPLFH, the Issuer and their respective affiliates, for which they received or may in the future receive customary fees and expenses.

In the ordinary course of their various business activities, the underwriters and certain of their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers, and such investment and securities activities may involve securities and/or instruments of LPLFH or its affiliates. If the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain of the underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, the underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities or the securities of our affiliates, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and certain of their affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the trustee under the Indenture governing the Notes.

Conflicts of Interest

Certain of the underwriters or their affiliates are lenders under our Existing Revolving Credit Facility and, as a result of the intended use of net proceeds from this offering to repay outstanding borrowings under our Existing Revolving Credit Facility, such underwriters or their affiliates may receive at least 5% of the net proceeds of this offering. The receipt of at least 5% of the net proceeds of this offering by any underwriter or its affiliates would be considered a ‘‘conflict of interest’’ under FINRA Rule 5121. As such, this offering is being conducted in accordance with the applicable requirements of Rule 5121. Rule 5121 requires prominent disclosure of the nature of the conflict of interest in the prospectus supplement for the public offering. Pursuant to Rule 5121(a)(1)(C), the appointment of a qualified independent underwriter is not necessary in connection with this offering as the securities offered are investment grade rated.

DESCRIPTION OF COMMON STOCK

References to the “Company,” “us,” “we” or “our” in this section mean LPL Financial Holdings Inc. and do not include the subsidiaries of LPL Financial Holdings Inc.

The following summary of the terms of our common stock does not purport to be complete. You should refer to our Amended and Restated Certificate of Incorporation (our “Certificate”) and our Sixth Amended and Restated Bylaws (our “Bylaws”), both of which are on file with the SEC as exhibits to previous filings. The summary below is also qualified by provisions of applicable law.

General

Under our Certificate, we have authority to issue up to 600,000,000 shares of common stock, par value $0.001 per share. Our common stock is registered under Section 12 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is listed on the Nasdaq Global Select Market under the symbol “LPLA”. As of September 18, 2023 we had 75,684,213 shares of common stock outstanding, held by 905 record holders.

Holders of our common stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. Our Bylaws provide that a nominee for director will be elected if the number of votes properly cast “for” such nominee’s election exceeds the number of votes properly cast “against” such nominee’s election; however, if the number of persons properly nominated for election to our board of directors (the “Board of Directors”) exceeds the number of directors to be elected, the directors will be elected by the plurality of the votes properly cast. Holders of common stock are entitled to receive proportionately any dividends as may be declared by our Board of Directors, subject to any preferential dividend rights of any series of preferred stock that is outstanding at the time of the dividend.

In the event of our liquidation or dissolution, the holders of common stock are entitled to receive proportionately our net assets available for distribution to stockholders after payment of all debts and other liabilities and subject to the prior rights of any outstanding preferred stock.

All shares of common stock will, when issued, be duly authorized, fully paid and nonassessable. The rights, preferences and privileges of holders of common stock are subject to the rights of the holders of shares of any series of preferred stock that the Company may designate and issue in the future.

Anti-takeover Effects of the Delaware General Corporation Law and our Certificate of Incorporation and Bylaws

Our Certificate and our Bylaws contain certain provisions that may discourage, delay or prevent a change in our management or control over us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with the Board of Directors, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, they may also discourage acquisitions that some stockholders may favor.

Action by Written Consent

The Delaware General Corporation Law (“DGCL”) provides that, unless otherwise stated in a corporation’s certificate of incorporation, the stockholders may act by written consent without a meeting. Our Certificate provides that any action required or permitted to be taken by our stockholders may only be taken at a duly called annual or special meeting of stockholders, and not by written consent without a meeting.

7

Special Meeting of Stockholders

Our Certificate and Bylaws provide that, subject to any special rights of the holders of any series of preferred stock and to the requirements of applicable law, special meetings of our stockholders can only be called by (a) our chairman or vice chairman of the Board of Directors, (b) our president or (c) a majority of the Board of Directors through a special resolution.

Advance Notice Requirements for Stockholder Proposals

Our Bylaws set forth advance notice procedures for stockholder proposals to be brought before an annual meeting of the stockholders, including the nomination of directors. Stockholders at an annual meeting may only consider the proposals specified in the notice of meeting, brought before the meeting by or at the direction of the Board of Directors or brought by a stockholder of record who is entitled to vote at the meeting and who has delivered a timely written notice in proper form (in accordance with both our Bylaws and applicable law) to our secretary of the stockholder’s intention to bring such business before the meeting. These provisions could have the effect of precluding the conduct of certain business at a meeting if the proper procedures are not followed or delaying until the next stockholder meeting stockholder actions that are favored by the holders of a majority of our outstanding voting securities.

Proxy Access

Our Bylaws provide that a stockholder (or a group of up to 20 stockholders) who has held at least 3% of our common stock for three years or more may nominate a specified number of directors and have those nominees included in our proxy materials, provided that the stockholder and nominees satisfy the requirements specified in our Bylaws. The maximum number of stockholder nominees permitted under these provisions is the greater of two or 20% of the number of directors in office. Any stockholder who intends to use these procedures to nominate a candidate for election to the Board of Directors for inclusion in our proxy statement must satisfy the requirements specified in our Bylaws.

Requirements for Removal and Interim Election of Directors

Subject to the special rights of the holders of any series of preferred stock to elect directors, holders of at least two-thirds of the shares entitled to vote at an election of the directors must approve the removal of directors. Vacancies and newly-created directorships will be filled only by a vote of a majority of the directors then in office, even though less than a quorum, and not by the stockholders. In addition, the Certificate provides that any vacancy created by the removal of a director by the stockholders shall only be filled by, in addition to any other vote otherwise required by law, the affirmative vote of a majority of the outstanding shares of common stock. Our Bylaws allow the presiding officer at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed.

These provisions may have the effect of deferring, delaying or discouraging hostile takeovers, or changes in control or management of our company.

Amendment to Certificate of Incorporation and Bylaws

The DGCL provides generally that the affirmative vote of a majority of the outstanding stock entitled to vote on amendments to a corporation’s certificate of incorporation or bylaws is required to approve such amendment, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our Bylaws may be amended or repealed by a majority vote of our Board of Directors or, in addition to any other vote otherwise required by law, the affirmative vote of at least two-thirds of the voting power of our outstanding shares of common stock. Additionally, the affirmative vote of at least two-thirds of the voting power of the outstanding shares of common stock is required to alter, amend or repeal, or to adopt any provision inconsistent with, the “Board of Directors,” “No Action by Written Consent,” “Special Meetings of Stockholders,” “Amendments to the Amended and Restated Certificate of Incorporation and Bylaws” and

8

“Business Combinations” provisions described in our Certificate. These provisions may have the effect of deferring, delaying or discouraging the removal of any anti-takeover defenses provided for in our Certificate and our Bylaws.

Exclusive Jurisdiction of Certain Actions

Our Certificate requires, to the fullest extent permitted by law, that derivative actions brought in the name of the Company, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery of the State of Delaware. Although we believe this provision benefits the Company by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against our directors and officers.

Authorized but Unissued Shares

The authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing standards of the Nasdaq Global Select Market. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans. The existence of authorized but unissued common stock and preferred stock could make more difficult, or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Business Combinations

We have elected to not be subject to Section 203 of the DGCL, which regulates business combinations with “interested stockholders.”

Transfer Agent and Registrar

The transfer agent and registrar for our common stock is Computershare Inc.

PLAN OF DISTRIBUTION

We may sell securities in any of the ways described below or in any combination:

The distribution of the securities by us may be effected from time to time in one or more transactions:

Each prospectus supplement will describe the method of distribution of the securities and any applicable restrictions.

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

Only the agents or underwriters named in each prospectus supplement are agents or underwriters in connection with the securities being offered thereby.

We may authorize underwriters, dealers or other persons acting as our agents to solicit offers by certain institutions to purchase securities from us pursuant to delayed delivery contracts providing for payment and delivery on the date stated in each applicable prospectus supplement. Each contract will be for an amount not less than, and the aggregate amount of securities sold pursuant to such contracts shall not be less nor more than, the respective amounts stated in each applicable prospectus supplement. Institutions with whom the contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but shall in all cases be subject to our approval. Delayed delivery contracts will be subject only to those conditions set forth in each applicable prospectus supplement, and each prospectus supplement will set forth any commissions we pay for solicitation of these contracts.

Agents, underwriters and other third parties described above may be entitled to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution from us with respect to payments which the agents, underwriters or third parties may be required to make in respect thereof. Agents, underwriters and such other third parties may be customers of, engage in transactions with or perform services for us in the ordinary course of business. We may also use underwriters or such other third parties with whom we have a material relationship. We will describe the nature of any such relationship in the applicable prospectus supplement.

Certain underwriters may use this prospectus and any accompanying prospectus supplement for offers and sales related to market-making transactions in the securities. These underwriters may act as principal or agent

10

in these transactions, and the sales will be made at prices related to prevailing market prices at the time of sale. Any underwriters involved in the sale of the securities may qualify as “underwriters” within the meaning of Section 2(a)(11) of the Securities Act. In addition, the underwriters’ commissions, discounts or concessions may qualify as underwriters’ compensation under the Securities Act and the rules of the Financial Industry Regulatory Authority.

Our common stock is listed on the Nasdaq Global Select Market. Underwriters may make a market in our common stock, but will not be obligated to do so and may discontinue any market making at any time without notice. We can make no assurance as to the development, maintenance or liquidity of any trading market for the securities.

Certain persons participating in an offering may engage in overallotment, stabilizing transactions, short covering transactions and penalty bids in accordance with rules and regulations under the Exchange Act. Overallotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short covering transactions involve purchases of the securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a dealer when the securities originally sold by the dealer are purchased in a covering transaction to cover short positions. Those activities may cause the price of the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time.
