KLA Corporation

 % Senior Notes due 20   

4.950% Senior Notes due 2052

We will issue   % Senior Notes due 20  (the “20  notes”) and 4.950% Senior Notes due 2052 (the “2052 notes” and, together with the 20    notes, the “notes”) in this offering.

The 2052 notes offered hereby will constitute a further issuance of our 4.950% Senior Notes due 2052, of which $1,200,000,000 aggregate principal amount was issued on June 23, 2022 (the “existing 2052 notes”). The 2052 notes will form a single series with, and have the same terms, other than the initial offering price, the issue date and the initial interest payment date, as the existing 2052 notes. Upon settlement, the 2052 notes will have the same CUSIP/ISIN number and will trade interchangeably with the existing 2052 notes. The offering price of the 2052 notes will include accrued interest from, and including, January 15, 2024 to, but excluding, the issue date of the 2052 notes, which must be paid by the purchasers of the 2052 notes. Immediately after giving effect to the issuance of the 2052 notes offered hereby, we will have $     aggregate principal amount of 4.950% Senior Notes due 2052 outstanding.

Interest on the 20     notes will accrue at the rate of  % per annum and interest on the 2052 notes will accrue at the rate of 4.950% per annum. We will pay interest on the 20   notes semi-annually on    and     of each year. We will pay interest on the 2052 notes semi-annually on January 15 and July 15 of each year. Interest will accrue on the 20   notes from    , 2024, and the first interest payment date will be    , 2024. Interest will accrue on the 2052 notes from, and including, January 15, 2024, and the first interest payment date will be July 15, 2024. The 20  notes will mature on    , 20  and the 2052 notes will mature on July 15, 2052. We may redeem some or all of the notes at any time at the applicable redemption prices. We will be required to make an offer to purchase the notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest to the date of repurchase, upon the occurrence of a Change of Control Triggering Event (as defined herein). See the section of this prospectus supplement entitled “Description of Notes—Redemption—Optional redemption” and “Description of Notes—Repurchase upon change of control triggering event” for more information.

The notes will be our unsecured senior obligations and will rank equally in right of payment with all of our unsecured and unsubordinated indebtedness. The notes will not be guaranteed by any of our subsidiaries. The notes will be effectively subordinated to any of our future secured indebtedness and structurally subordinated in right of payment to all indebtedness and other liabilities of our subsidiaries.

Investing in the notes involves risks that are described in the “Risk Factors ” section beginning on page S-6 of this prospectus supplement. See the “Risk Factors” section in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023 and Quarterly Reports on Form 10-Q for the quarters ended September 30, 2023 and December 31, 2023, which are incorporated by reference herein, for a discussion of certain risks that should be considered in connection with an investment in the notes.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement, the accompanying prospectus and documents that are incorporated by reference into this prospectus supplement and the accompanying prospectus contain certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”) and Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact may be forward-looking statements. You can identify these and other forward-looking statements by the use of words such as “may,” “will,” “could,” “would,” “should,” “expects,” “plans,” “anticipates,” “relies,” “believes,” “estimates,” “predicts,” “intends,” “potential,” “continues,” “thinks,” “seeks” or the negative of such terms, or other comparable terminology. Forward-looking statements also include the assumptions underlying or relating to any of the foregoing statements. These forward-looking statements are based on current information and expectations, and involve a number of risks and uncertainties. We claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 for all forward-looking statements.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as the future impacts of the COVID-19 pandemic; forecasts of the future results of our operations, including profitability; orders for our products and capital equipment generally; sales of semiconductors; the investments by our customers in advanced technologies and new materials; growth of revenue in the semiconductor industry, the semiconductor capital equipment industry and our business; technological trends in the semiconductor industry; future developments or trends in the global capital and financial markets; our future product offerings and product features; the success and market acceptance of new products; timing of shipment of order backlog; our future product shipments and product and service revenues; our future gross margins; our future research and development (“R&D”) expenses and selling, general and administrative expenses; international sales and operations; our ability to maintain or improve our existing competitive position; success of our product offerings; creation and funding of programs for R&D; results of our investment in leading edge technologies; the effects of hedging transactions; the effect of the sale of trade receivables and promissory notes from customers; the effect of future compliance with laws and regulations; our future effective income tax rate; our recognition of tax benefits; the effects of any audits or litigation; future payments of dividends to our stockholders; the completion of any acquisitions of third parties, or the technology or assets thereof; benefits received from any acquisitions and development of acquired technologies; sufficiency of our existing cash balance, investments, cash generated from operations and the unfunded portion of our Revolving Credit Facility (as defined herein) to meet our operating and working capital requirements, including debt service and payment thereof; future dividends, and stock repurchases; our compliance with the financial covenants under the Credit Agreement (as defined herein) for our Revolving Credit Facility; the adoption of new accounting pronouncements; our repayment of our outstanding indebtedness; and our environmental, social and governance (“ESG”) related targets, goals and commitments.

Actual results may differ significantly from those projected in such statements due to various factors, including, but not limited to: our vulnerability to a weakening in the condition of the financial markets and the global economy; risks related to our international operations; evolving Bureau of Industry and Security of the U.S. Department of Commerce rules and regulations and their impact on our ability to sell products to and provide services to certain customers in People’s Republic of China; costly intellectual property disputes that could result in our inability to sell or use the challenged technology; risks related to the legal, regulatory and tax environments in which we conduct our business; increasing attention to ESG matters and the resulting costs, risks and impact on our business; unexpected delays, difficulties and expenses in executing against our environmental, climate, diversity and inclusion or other ESG targets, goals and commitments; our ability to attract, retain and motivate key personnel; our vulnerability to disruptions and delays at our third party service providers; cybersecurity threats, cyber incidents affecting our and our business partners’ systems and networks; our inability to access critical information in a timely manner due to system failures; our ability to identify suitable acquisition targets and successfully integrate and manage acquired businesses; climate change, earthquake, flood or other natural catastrophic events, public health crises such as the COVID-19 pandemic or

S-iv

terrorism and the adverse impact on our business operations; the war between Israel and Hamas, and the significant military activity in that region; lack of insurance for losses and interruptions caused by terrorists and acts of war, and our self-insurance of certain risks including earthquake risk; risks related to fluctuations in foreign currency exchange rates; risks related to fluctuations in interest rates and the market values of our portfolio investments; risks related to tax and regulatory compliance audits; any change in taxation rules or practices and our effective tax rate; compliance costs with federal securities laws, rules, regulations, NASDAQ requirements, and evolving accounting standards and practices; ongoing changes in the technology industry, and the semiconductor industry in particular, including future growth rates, pricing trends in end-markets, or changes in customer capital spending patterns; our vulnerability to a highly concentrated customer base; the cyclicality of the industries in which we operate; our ability to timely develop new technologies and products that successfully address changes in the industry; our ability to maintain our technology advantage and protect proprietary rights; our ability to compete in the industry; availability and cost of the materials and parts used in the production of our products; our ability to operate our business in accordance with our business plan; risks related to our debt and leveraged capital structure; we may not be able to declare cash dividends at all or in any particular amount; liability to our customers under indemnification provisions if our products fail to operate properly or contain defects or our customers are sued by third parties due to our products; our government funding for R&D is subject to audit, and potential termination or penalties; we may incur significant restructuring charges or other asset impairment charges or inventory write offs; and we are subject to risks related to receivables factoring arrangements and compliance risk of certain settlement agreements with the government.

We also refer you to those factors discussed in “Risk Factors” included in documents that we file from time to time with the SEC, including KLA’s Annual Report on Form 10-K for the fiscal year ended June 30, 2023 and Quarterly Reports on Form 10-Q for the quarters ended September 30, 2023 and December 31, 2023, which are incorporated by reference herein.

We have no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or risks, except to the extent required by applicable securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements. New information, future events or risks could cause the forward-looking events we discuss in this prospectus supplement and the accompanying prospectus not to occur. You should not place undue reliance on these forward-looking statements, which reflect our expectations only as of the date of this prospectus supplement and the accompanying prospectus or as of the date of the documents incorporated by reference herein, as applicable.

RISK FACTORS

Any investment in the notes involves a high degree of risk. You should carefully consider the risks described below and all of the information included or incorporated by reference in this prospectus supplement and accompanying prospectus before deciding whether to purchase the notes. The risks and uncertainties described below are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations. If any of the events or circumstances described in the following risk factors actually occur, our business, financial condition and results of operations would suffer. In that event, the price of the notes could decline, and you may lose all or part of your investment. The risks discussed below and in the documents incorporated by reference also include forward-looking statements, and our actual results may differ substantially from those discussed in these forward-looking statements. See “Special Note Regarding Forward-Looking Statements.”

Risks relating to the notes

The notes are structurally subordinated to any future indebtedness and to the other liabilities of our subsidiaries.

The notes are our obligations exclusively and not of any of our subsidiaries. A significant portion of our operations is conducted through our subsidiaries. Our subsidiaries are separate legal entities that have no obligation to pay any amounts due under the notes or to make any funds available therefor, whether by dividends, loans or other payments. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors, including trade creditors, and holders of preferred stock, if any, of our subsidiaries will have priority with respect to the assets of such subsidiaries over our claims (and, therefore, the claims of our creditors, including holders of the notes), and our subsidiaries may enter into future borrowing arrangements that limit their ability to transfer funds to us. Consequently, the notes will be structurally subordinated to all liabilities, including trade payables, of any of our subsidiaries and any subsidiaries that we may in the future acquire or establish. All borrowings under our Credit Agreement, dated as of June 8, 2022 (the “Credit Agreement”), which provides for a $1.5 billion five-year unsecured revolving credit facility, are guaranteed on an unsecured basis by certain of our material domestic subsidiaries. As of December 31, 2023, our subsidiaries had approximately $1.88 billion of liabilities (including trade payables but excluding intercompany obligations and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP). In addition, the indenture governing the notes permits our subsidiaries to incur additional secured indebtedness, and does not contain any limitation on the amount of unsecured indebtedness or other liabilities, such as trade payables, that may be incurred by our subsidiaries.

The notes will be subject to the prior claims of any future secured creditors.

The notes are unsecured obligations, ranking effectively junior to any secured indebtedness we may incur. As of December 31, 2023, we did not have any outstanding secured indebtedness, although the indenture governing the notes does not limit the amount of additional unsecured debt that we and our subsidiaries may incur and permits us to incur secured debt under specified circumstances. If we incur secured debt, our assets securing any such indebtedness will be subject to prior claims by our secured creditors. In the event of our bankruptcy, insolvency, liquidation, reorganization, dissolution or other winding up, or upon any acceleration of the notes, our assets that secure debt will be available to pay obligations on the notes only after all debt secured by those assets has been repaid in full. Holders of the notes will participate in any remaining assets ratably with all of our other unsecured and unsubordinated creditors, including trade creditors. If there are not sufficient assets remaining to pay all these creditors, then all or a portion of the notes then outstanding would remain unpaid.

The terms of our Credit Agreement restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.

Our Credit Agreement contains restrictive covenants that impose operating and financial restrictions on us

S-7

and may limit our ability to engage in acts that may be in our long-term best interest, including restrictions on our and our subsidiaries’ ability to:

The Credit Agreement contains certain customary representations and warranties, affirmative covenants and events of default.

In addition, the restrictive covenants in the Credit Agreement require us to maintain specified financial ratios and satisfy other financial condition tests. Our ability to meet those financial ratios and tests may be affected by events beyond our control, and we may be unable to meet them. You should read the discussion under the heading “Description of Other Indebtedness” for further information about these covenants.

A breach of the covenants or restrictions under the Credit Agreement could result in an event of default thereunder. Such a default may allow the lenders thereunder to accelerate the loans and may result in the acceleration of any other debt which has a cross-acceleration or cross-default provision that applies to the Credit Agreement. In addition, an event of default under the Credit Agreement would permit the lenders to terminate all commitments to extend further credit under the Credit Agreement. In the event our lenders or other debt holders accelerate the repayment of any borrowings that may be outstanding, we and our subsidiaries may not have sufficient assets or liquidity to repay that indebtedness.

The negative covenants in the indenture that governs the notes provide limited protection to holders of the notes.

The indenture governing the notes contains covenants limiting our ability and our subsidiaries’ ability to create certain liens, enter into certain sale and lease-back transactions, and consolidate or merge with, or convey, transfer or lease all or substantially all our assets to, another person. The limitation on liens and limitation on sale and lease-back covenants contain exceptions that will allow us and our subsidiaries to incur liens with respect to material assets. See “Description of Notes—Certain covenants.” In light of these exceptions, holders of the notes may be structurally or effectively subordinated to new lenders.

Despite our increased consolidated debt levels, we and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our debt instruments, some of which may be secured debt. We will not be restricted under the terms of the indenture governing the notes from incurring additional unsecured debt or taking a number of other actions that are not limited by the terms of the indenture governing the notes that could have the effect of diminishing our ability to make payments on the notes when due.

Dividends and repurchases of our common stock under our stock repurchase program will reduce funds available for repayment of the notes.

We have historically paid quarterly dividends and intend to continue to do so subject to capital availability and periodic determinations by our Board of Directors. On September 2, 2023, our Board of Directors authorized a share repurchase program which permits us to repurchase up to an aggregate of $2.0 billion of shares of our common stock. This share repurchase program is in addition to the $6.0 billion share repurchase program

S-8

announced in June 2022, which as of December 31, 2023 had approximately $3.02 billion of repurchase authority remaining. We expect to continue these repurchases in the future using cash, including proceeds from this offering, or other of our assets. The amount of our future repurchases may be significant, and the indenture governing the notes does not limit our ability to conduct future repurchases in any way. Similarly, the indenture governing the notes does not limit our ability to pay dividends. Any future dividends or repurchases by us would reduce the cash and stockholders’ equity that is available to repay the notes.

The provisions of the notes will not necessarily protect you in the event of certain highly leveraged transactions.

Upon the occurrence of a Change of Control Triggering Event (as defined under “Description of Notes—Repurchase upon change of control triggering event”), you will have the right to require us to repurchase the notes. However, the Change of Control Triggering Event provisions will not afford you protection in the event of certain highly leveraged transactions that may adversely affect you. For example, any leveraged recapitalization, refinancing, restructuring or acquisition initiated by us will generally not constitute a Change of Control (as defined herein) that would potentially lead to a Change of Control Triggering Event. As a result, we could enter into any such transaction even though the transaction could increase the total amount of our outstanding indebtedness, adversely affect our capital structure or credit ratings or otherwise adversely affect the holders of the notes. These transactions may not involve a change in voting power or beneficial ownership or result in a downgrade in the ratings of the notes, or, even if they do, may not necessarily constitute a Change of Control Triggering Event that affords you the protections described in this prospectus supplement. If any such transaction were to occur, the value of your notes could decline.

You may not be entitled to require us to repurchase your notes in certain circumstances involving our Board of Directors, including in connection with a proxy contest, where our Board of Directors does not endorse a dissident slate of directors, but approves such directors as Continuing Directors (as defined herein) for purposes of the indenture governing the notes. This may result in a change in the composition of the Board of Directors that, but for such subsequent approval, would have otherwise constituted a Change of Control that would potentially lead to a Change of Control Triggering Event, in which case you will not have the right to require us to repurchase all or a portion of your notes.

We may not be able to repurchase all of the notes upon a Change of Control Triggering Event, which would result in a default under the notes.

We will be required to offer to repurchase the notes upon the occurrence of a Change of Control Triggering Event as provided in the indenture governing the notes. However, we may not have sufficient funds to repurchase the notes in cash at that time. In addition, our ability to repurchase the notes for cash may be limited by law or the terms of other agreements relating to our indebtedness outstanding at the time, which agreements may provide that a Change of Control Triggering Event constitutes an event of default or prepayment under such indebtedness. Our failure to make such a repurchase would result in a default under the notes and our Revolving Credit Facility, and may constitute an event of default under our future debt instruments.

Redemption 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—Redemption—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 amount received upon a redemption in a comparable security at an effective interest rate as high as that of the notes.

Our substantial leverage could have a significant effect on our operations and on our ability to secure additional financing when needed.

After giving effect to the issuance of the notes offered hereby, our total indebtedness for borrowed money as of December 31, 2023 would have been approximately $5.95 billion. Our ability to repay or refinance our

S-9

indebtedness or to secure additional capital resources to fund our business will depend upon, among other things, our operating performance. Such future operating results may be affected by general economic, competitive, business and other factors beyond our control. Although we believe that our future cash flow from operating activities, together with available financing arrangements, will be sufficient to fund our operating, strategic growth, capital expenditure and debt service requirements, if we fail to meet our financial obligations or if supplemental financing is not available to us on satisfactory terms when needed, our business could be harmed.

We will be required to dedicate a substantial portion of our cash flow to the payment of principal and interest on our indebtedness, which could reduce the amount of discretionary funds available for our other operational needs and growth objectives.

We may also be more vulnerable in the event of a deterioration of our business or changes in the semiconductor industry or the economy in general, because of our increased need for cash flow.

In the event of a default, we may be forced to pursue one or more alternative strategies, such as restructuring or refinancing our indebtedness, selling assets, reducing or delaying capital expenditures or seeking additional equity capital. There can be no assurances that any of these strategies could be effectuated on satisfactory terms, if at all, or that sufficient funds could be obtained to make the requisite debt service payments.

Changes in our credit ratings may adversely affect the value of the notes.

Any ratings of the notes are limited in scope and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. An explanation of the significance of such rating may be obtained from such rating agency. There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s judgment, circumstances so warrant. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the market value of the notes and increase our corporate borrowing costs.

There may not be an active trading market for the notes.

There is no existing market for any series of the notes, and we do not intend to apply for listing of the notes on any securities exchange or any automated quotation system. Accordingly, there can be no assurance that a trading market for the notes will ever develop or will be maintained. Further, there can be no assurance as to the liquidity of any market that may develop for the notes, your ability to sell your notes or the price at which you will be able to sell your notes. Future trading prices of the notes will depend on many factors, including, but not limited to, prevailing interest rates, our financial condition and results of operations, prospects for companies in our industry generally, the then-current ratings assigned to the notes and the market for similar securities. Any trading market that develops for any series of the notes would be affected by many factors independent of and in addition to the foregoing, including:

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

In general, as market interest rates rise, notes bearing interest at a fixed rate generally decline in value. Consequently, if you purchase the notes and market interest rates increase, the market value of your notes may decline. We cannot predict the future level of market interest rates.

Risks related to our business

We operate in a rapidly changing economic and technological environment that presents numerous risks, many of which are driven by factors that we cannot control or predict. The risk factors set forth in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023 and Quarterly Reports on Form 10-Q for the quarters ended September 30, 2023 and December 31, 2023, which are incorporated by reference into this prospectus supplement and the accompanying prospectus, highlight some of these risks. You should read our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q, including the sections entitled “Risk Factors.”

S-11

USE OF PROCEEDS

We estimate that we will receive net proceeds from the offering of the notes of approximately $  billion after deducting underwriting discounts, other estimated offering expenses payable by us in connection with the offering of the notes and accrued interest paid by purchasers of the 2052 notes. See “Underwriting.” We intend to use the net proceeds from this offering for general corporate purposes, including the repayment of outstanding indebtedness at or prior to maturity, and to repurchase shares of our common stock pursuant to our previously announced share repurchase programs.

We may temporarily invest funds that are not immediately needed for these purposes in short-term investments, including cash, cash equivalents or marketable securities or used to reduce outstanding short-term borrowings.

CAPITALIZATION

DESCRIPTION OF NOTES

General

For purposes of this section, references to “KLA,” “we,” “us” and “our” are references to KLA Corporation only and not to any of its subsidiaries. We will issue the  % Senior Notes due 20     (the “20     notes”) and the 4.950% Senior Notes due 2052 (the “2052 notes” and, together with the 20  notes, the “notes”) as separate series of debt securities under an indenture dated as of June 23, 2022 (the “Indenture”) between us and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), and (i) in the case of the 20  notes, an officer’s certificate, to be dated as of     , 2024, and (ii) in the case of the 2052 notes, an officer’s certificate, dated as of June 23, 2022 (the date of issuance for the existing 2052 notes (as defined herein)). The term “Indenture,” as used herein, includes any Officer’s Certificate (as defined in the Indenture) or supplemental indenture establishing the form and terms of the Securities (as defined in the Indenture) pursuant to the Indenture. Pursuant to the Indenture, on June 23, 2022 we issued $1,200,000,000 aggregate principal amount of 4.950% Senior Notes due 2052 (the “existing 2052 notes”). The 2052 notes will be issued as additional notes of the same series as the existing 2052 notes under the Indenture. Each series of the notes will be issued as a separate series of debt securities under the Indenture, in the case of the 2052 notes, together with the existing 2052 notes, and will be treated as such for all purposes under the Indenture, including, without limitation, waivers, amendments and redemptions.

The following is a summary of the material provisions of the Indenture. It does not include all of the provisions of the Indenture. We urge you to read the Indenture because it defines your rights. The terms of the notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”). A copy of the Indenture may be obtained from us. You can find definitions of certain capitalized terms used in this description under “—Certain definitions.”

We will issue the notes of each series in fully registered form in denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Trustee will initially act as Paying Agent and Registrar for the notes. The notes may be presented for registration of transfer and exchange at the offices of the Registrar. We may change any Paying Agent and Registrar without notice to holders of the notes (the “Holders”). We will pay principal (and premium, if any) on notes in global form at the Trustee’s corporate office, which, initially, will be the corporate trust operations office of the Trustee located at One California Street, Suite 1000, San Francisco, California 94111, Attention: D. Jason (KLA Corporation Administrator). Interest on certificated notes will be paid by wire transfer of immediately available funds to the account specified by the Holder thereof to the paying agent or, if no such account is specified, by mailing a check to such Holder’s registered address. The transferor of any note shall provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including, without limitation, any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

Principal, maturity and interest

We will issue $     in aggregate principal amount of the 20     notes in this offering. We will issue $     in aggregate principal amount of the 2052 notes in this offering, which will constitute a further issuance of the existing 2052 notes, of which $1,200,000,000 aggregate principal amount was issued on June 23, 2022. The 2052 notes will form a single series with the existing 2052 notes under the Indenture and will have the same terms, other than the initial offering price, the issue date and the initial interest payment date, as the existing 2052 notes. Immediately upon settlement, the 2052 notes will have the same CUSIP/ISIN number and will trade interchangeably with the existing 2052 notes. Upon completion of this offering, an aggregate principal amount of $     of 4.950% Senior Notes due 2052 will be outstanding. The 20     notes will mature on     , 20     and the 2052 notes will mature on July 15, 2052. Interest on the 20   notes will accrue at the rate of  % per annum and interest on the 2052 notes will accrue at the rate of 4.950% per annum. Interest on each series of the notes will be payable semi-annually in arrears on, in the case of the 20   notes,

S-14

     and      of each year, commencing on     , 2024, and, in the case of the 2052 notes, January 15 and July 15 of each year, commencing on July 15, 2024, to the persons who are registered Holders of the relevant series of the notes at the close of business on, in the case of the 20   notes,      and     , and, in the case of the 2052 notes, January 1 and July 1, whether or not a Business Day, immediately preceding the applicable interest payment date.

Interest on the 20   notes will accrue from the most recent date to which interest has been paid or, if no interest has been paid, from and including the issue date. Interest on the 2052 notes will accrue from and including January 15, 2024, and, thereafter, from and including the most recent date to which interest has been paid. The offering price of the 2052 notes will include accrued interest from, and including, January 15, 2024, to, but excluding, the issue date of the 2052 notes, totaling $     in the aggregate for all 2052 notes offered hereby, which must be paid by the purchasers of the 2052 notes. If any interest payment date, redemption date, repurchase date or maturity date falls on a day which is not a Business Day, payment of interest, principal and premium, if any, with respect to such notes will be made on the next Business Day with the same force and effect as if made on the due date, and no interest on such payment will accrue from and after such due date. Interest for each series of notes will be computed on the basis of a 360-day year composed of twelve 30-day months.

We may from time to time without notice to, or the consent of, any Holder, create and issue additional series of notes under the Indenture. To the extent we do so, the separate series of notes will not vote together as a single series on any matters. We may also from time to time without notice to, or the consent of, any Holder, create and issue additional notes of any series offered hereby under the Indenture equal in rank to the notes of such series in all respects (or in all respects except for the issue date, issue price, the payment of interest accruing prior to the issue date of such additional notes, or the first payment of interest following the issue date of such additional notes) so that the additional notes may be consolidated and form a single series with the notes of such series, and have the same terms as to status, redemption and otherwise as the notes of such series; provided that, if any such additional notes are not fungible with the notes of the relevant series initially offered hereby for U.S. federal income tax purposes, such additional notes will have one or more separate CUSIP numbers.

The notes will not be guaranteed by any of our subsidiaries. The notes will not be entitled to the benefit of any mandatory sinking fund.

We will pay interest (including post-petition interest in any proceeding under any bankruptcy law) on overdue payments of the principal, purchase price and redemption price of the notes of any applicable series from time to time on demand at the rate then borne by the notes of that series; and will pay interest (including post-petition interest in any proceeding under any bankruptcy law) on overdue installments of interest, if any (without regard to any applicable grace periods), on the notes of that series from time to time on demand at the same rate to the extent lawful.

Ranking

The notes will be our unsecured senior obligations and will:

As of December 31, 2023, we had $5.95 billion of indebtedness for borrowed money, none of which was secured indebtedness, and our subsidiaries had approximately $1.88 billion of liabilities (including trade payables

S-15

but excluding intercompany obligations and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with U.S. generally accepted accounting principles (“GAAP”)) to which the notes would have been structurally subordinated.

Redemption

Optional redemption

Prior to the applicable Par Call Date (as defined below), we may redeem notes of any series at our 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 on such series of notes discounted to the redemption date (assuming such series of 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 (as defined below) plus (i)  basis points in the case of the 20     notes or (ii) 25 basis points in the case of the 2052 notes, in each case, less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the notes of such series to be redeemed,

plus, in either case, accrued and unpaid interest on the respective series of notes to be redeemed to, but not including, the applicable redemption date.

On or after the applicable Par Call Date, we may redeem the applicable series of notes at our option, 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 not including, the redemption date.

Our actions and determinations in determining the applicable redemption price shall be conclusive and binding for all purposes, absent manifest error.

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

Selection and notice of redemption

In the event that we choose to redeem less than all of a series of notes, selection of the notes for redemption will be made by the Trustee on a pro rata basis, by lot or by such method as the Trustee shall deem fair and appropriate and, in the case of global notes, in accordance with the applicable procedures of the Depositary (as defined below).

No notes of a principal amount of $2,000 or less shall be redeemed in part. Notice of any 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 notes to be redeemed. If any note is to be redeemed in part only, the notice of redemption that relates to such note shall state the portion of the principal amount thereof to be redeemed. A new note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon surrender for cancellation of the original note or in the case of a global note the new principal amount will be reflected on the schedule to the global note. On and after the redemption date, interest will cease to accrue on notes of each series or portions thereof called for redemption as long as we have deposited with the Paying Agent funds in satisfaction of the applicable redemption price. For so long as the notes are held by DTC (or another Depositary), the redemption of the notes of any series shall be done in accordance with the policies and procedures of the Depositary.

Repurchase upon change of control triggering event

If a Change of Control Triggering Event (as defined below) occurs with respect to a series of notes, unless we have exercised our right to redeem the notes of such series as described above, we will be required to make an offer

S-16

to repurchase all or, at the Holder’s option, any part (equal to $2,000 or any integral multiple of $1,000 in excess thereof), of each Holder’s notes of that series pursuant to the offer described below (the “Change of Control Offer”) on the terms set forth in the notes. In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of notes repurchased plus accrued and unpaid interest, if any, on the notes repurchased, to, but not including, the date of purchase (the “Change of Control Payment”).

Within 30 days following any Change of Control Triggering Event with respect to a series of notes, we will be required to give notice to Holders of notes of that series, with a copy to the Trustee, describing the transaction or transactions that constitute the Change of Control Triggering Event and offering to repurchase the notes on the date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is given (the “Change of Control Payment Date”), pursuant to the procedures required by the notes and described in such notice. We must comply with the requirements of applicable securities laws and regulations in connection with the repurchase of the notes as a result of a Change of Control Triggering Event.

On the Change of Control Payment Date, we will be required, to the extent lawful, to:

The Paying Agent will be required to promptly give, to each Holder who properly tendered notes, the purchase price for such notes, and the Trustee will be required to promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any; provided that each new note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

We will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all notes properly tendered and not withdrawn under its offer. In the event that such third party terminates or otherwise fails to complete its offer, we will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event.

We will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the notes as a result of a Change of Control Triggering Event. To the extent that the provision of any such securities laws or regulations conflicts with the Change of Control Offer provisions of the notes, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the notes by virtue of any such conflict. For purposes of the repurchase provisions of the notes, the following terms will be applicable:

“Change of Control” means the occurrence of any one of the following: (1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger, amalgamation, arrangement or consolidation), in one or a series of related transactions, of all or substantially all of our properties or assets and those of our subsidiaries, taken as a whole, to one or more persons, other than to us or one of our subsidiaries; (2) the first day on which a majority of the members of our board of directors is not composed of Continuing Directors (as defined below); (3) the consummation of any transaction including, without limitation, any merger, amalgamation, arrangement or consolidation the result of which is that any person becomes the beneficial owner, directly or indirectly, of more than 50% of our Voting Stock; (4) we consolidate with, or merge with or into, any

S-17

person, or any person consolidates with, or merges with or into, us, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of us or of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of our Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person immediately after giving effect to such transaction; or (5) the adoption of a plan relating to our liquidation or dissolution. For the purposes of this definition, “person” and “beneficial owner” have the meanings used in Section 13(d) of the Exchange Act.

“Change of Control Triggering Event,” with respect to a series of notes, means the notes of that series cease to be rated Investment Grade by at least two of the three Rating Agencies on any date during the period (the “Trigger Period”) commencing on the date of the first public notice of the occurrence of a Change of Control or our intention to effect a Change of Control and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following consummation of a Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change). Unless at least two of the three Rating Agencies are providing a rating for the notes of a series at the commencement of any Trigger Period, the notes of that series will be deemed to have ceased to be rated Investment Grade by at least two of the three Rating Agencies during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Continuing Directors” means, as of any date of determination, any member of our Board of Directors who (1) was a member of our Board of Directors on the Issue Date; or (2) was nominated for election, elected or appointed to our Board of Directors with the approval of a majority of the Continuing Directors who were members of our Board of Directors at the time of such nomination, election or appointment (either by a specific vote or by approval by such directors of our proxy statement in which such member was named as a nominee for election as a director).

“Depositary” means, with respect to the notes, a clearing agency registered under the Exchange Act that is designated to act as depositary for such notes in accordance with the terms of the Indenture.

“Fitch” means Fitch Ratings, Inc., and its successors.

“Investment Grade” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s, BBB- (or the equivalent) by S&P or BBB- (or the equivalent) by Fitch, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by us.

“Moody’s” means Moody’s Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors.

“Rating Agencies” means (a) each of Moody’s, S&P and Fitch to the extent Fitch makes its rating available; and (b) if any of the Rating Agencies ceases to rate the notes or fails to make a rating of the notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” as such term is defined in Section 3(a)(62) of the Exchange Act that is selected by us (as certified by a resolution of our Board of Directors) as a replacement for Moody’s, S&P or Fitch, or some or all of them, as the case may be.

“S&P” means Standard & Poor’s Global Ratings, a division of S&P Global Inc., and its successors.

“Voting Stock” of any specified person as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the Board of Directors of such person.

Holders may not be entitled to require us to purchase their notes in certain circumstances involving our Board of Directors, including in connection with a proxy contest, where our Board of Directors does not endorse a dissident slate of directors, but approves such directors as Continuing Directors for purposes of the Indenture. This may result in a change in the composition of the Board of Directors that, but for such subsequent approval, would have otherwise constituted a Change of Control, in which case you will not have the right to require us to repurchase all or a portion of your notes.

S-18

Certain covenants

The Indenture will contain, among others, the following covenants:

Limitation on liens

We will not (nor will we permit any of our Domestic Subsidiaries to) issue, incur, create, assume or guarantee any Indebtedness secured by a Lien upon any Principal Property or upon any of the Capital Stock or Indebtedness of any of our Subsidiaries (whether such Principal Property, or Capital Stock or Indebtedness is now existing or owed or hereafter created or acquired) without in any such case effectively providing, concurrently with the issuance, incurrence, creation, assumption or guaranty of any such secured Indebtedness, or the grant of such Lien, that the notes of each series then outstanding (together with, if we shall so determine, any other Indebtedness of or guarantee by us or such Subsidiary ranking equally with the notes) shall be secured equally and ratably with (or, at our option, prior to) such secured Indebtedness. The foregoing restriction, however, will not apply to any of the following:

Limitation on sale and lease-back transactions

We will not, nor will we permit any of our Subsidiaries to, enter into any Sale and Lease-Back Transaction with respect to any Principal Property, other than any such Sale and Lease-Back Transaction involving a lease for a term of not more than three years or any such Sale and Lease-Back Transaction between us and one of our Subsidiaries or between our Subsidiaries, unless: (a) we or such Subsidiary, as applicable, would be entitled to incur Indebtedness secured by a Lien on the Principal Property involved in such Sale and Lease-Back Transaction in an amount at least equal to the Attributable Debt with respect to such Sale and Lease-Back

S-19

Transaction, without equally and ratably securing the notes of each series then outstanding, pursuant to the covenant described above under the caption “— Limitation on liens”; or (b) the proceeds of such Sale and Lease-Back Transaction are at least equal to the fair market value of the affected Principal Property (as determined in good faith by our Board of Directors) and we apply an amount equal to the net proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale and Lease-Back Transaction to any (or a combination) of (i) the prepayment or retirement of the notes, (ii) the prepayment or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by payment at maturity) of other Indebtedness of us or of one of our Subsidiaries (other than Indebtedness that is subordinated to the notes or Indebtedness owed to us or one of our Subsidiaries) that matures more than 12 months after its creation or (iii) the purchase, construction, development, expansion or improvement of other comparable property.

Limitation on mergers and other transactions

We may not merge or consolidate with any other person or persons (whether or not affiliated with us), and we may not sell, convey, transfer, lease or otherwise dispose of all or substantially all of our property or assets to any other person or persons (whether or not affiliated with us), unless the following conditions are satisfied:

(1) either (a) the transaction is a merger or consolidation, and we are the surviving entity; or (b) the successor person (or the person which acquires by sale, conveyance, transfer or lease all or substantially all of our property or assets) is a corporation organized under the laws of the United States, any state thereof or the District of Columbia and expressly assumes, by a supplemental indenture satisfactory to the Trustee, all of our obligations under the notes and the Indenture;

(2) immediately after giving effect to the transaction and treating our obligations in connection with or as a result of such transaction as having been incurred as of the time of such transaction, no Default or Event of Default shall have occurred and be continuing under the Indenture; and

(3) an officer’s certificate and opinion of counsel is delivered to the Trustee to the effect that such transaction, and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, complies with this “—Limitation on mergers and other transactions” and that all conditions precedent under the Indenture relating to such transaction have been complied with.

In the case of any such consolidation, merger, sale, transfer or other conveyance, but not a lease, in a transaction in which there is a successor entity, the successor entity will succeed to, and be substituted for, us under the Indenture and, subject to the terms of the Indenture, we will be released from the obligation to pay principal and interest on the notes and all obligations under the Indenture.

Reports to holders

The Indenture provides that any document or report that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act will be filed with the Trustee within 30 days after such document or report is required to be filed with the SEC. Documents filed by us with the SEC via the EDGAR system (or any successor thereto) will be deemed to be filed with the Trustee as of the time such documents are filed via EDGAR, it being understood that the Trustee shall not be responsible for determining whether such filings have been made. Delivery of the information, documents and other reports described above to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including our compliance with any of the covenants under the Indenture (as to which the Trustee is entitled to conclusively rely on an officer’s certificate).

S-20

Events of default

The following events will be defined in the Indenture as “Events of Default” with respect to the notes of a series:

(1) the failure to pay interest on any note of such series when the same becomes due and payable and the default continues for a period of 30 days;

(2) the failure to pay the principal (or premium, if any) of any note of such series, when such principal becomes due and payable, at maturity, upon acceleration, upon redemption or otherwise (including the failure to make a payment to purchase notes of such series tendered pursuant to a Change of Control Offer);

(3) a default in the performance, or breach, of our obligations under the “—Certain covenants—Limitation on mergers and other transactions” covenant described above;

(4) a Default in the observance or performance of any other covenant or agreement contained in the Indenture which Default continues for a period of 60 days after we receive written notice specifying the Default (and demanding that such Default be remedied) from the Trustee or the Holders of at least 25% of the outstanding principal amount of the notes of such series;

(5) (a) a failure to make any payment at the stated maturity on any of our Indebtedness (other than Indebtedness owing to any of our Subsidiaries) outstanding in an amount in excess of $100.0 million or its foreign currency equivalent at the time and continuance of this failure to pay after any applicable grace period or (b) a Default on any of our Indebtedness (other than Indebtedness owing to any of our Subsidiaries), which Default results in the acceleration of such Indebtedness in an amount in excess of $100.0 million or its foreign currency equivalent at the time without such Indebtedness having been discharged or the acceleration having been cured, waived, rescinded or annulled, in the case of clause (a) or (b) above; provided, however, that, if any failure, default or acceleration referred to in clauses 5(a) or (b) ceases or is cured, waived, rescinded or annulled, then the Event of Default under the Indenture will be deemed cured; or

(6) certain events of bankruptcy or insolvency affecting us or any of our Significant Subsidiaries.

If an Event of Default (other than an Event of Default with respect to us specified in clause (6) above) shall occur and be continuing with respect to any series of notes, the Trustee or the Holders of at least 25% of the principal amount of such series of notes may declare the principal of, premium, if any, and accrued interest on all notes of such series to be due and payable by notice in writing to us and the Trustee specifying the respective Event of Default and that it is a “notice of acceleration,” and the same shall become immediately due and payable.

Notwithstanding the foregoing, if an Event of Default specified in clause (6) with respect to us (but not any of our Significant Subsidiaries) above occurs and is continuing, then all unpaid principal of and premium, if any, and accrued and unpaid interest on all notes shall automatically become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holder.

The Indenture will provide that, at any time after a declaration of acceleration with respect to a series of notes as described in the preceding paragraph, the Holders of a majority in principal amount of such series of notes (including additional notes of such series, if any) may rescind and cancel such declaration and its consequences if:

(1) the rescission would not conflict with any judgment or decree;

(2) all existing Events of Default with respect to such series of notes have been cured or waived except nonpayment of principal or interest that has become due solely because of the acceleration;

S-21

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid;

(4) we have paid the Trustee its compensation and reimbursed the Trustee for its expenses, disbursements and advances; and

(5) in the event of the cure or waiver of an Event of Default of the type described in clause (6) of the description above of Events of Default, the Trustee shall have received an officer’s certificate and an opinion of counsel that such Event of Default has been cured or waived.

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereto.

The Holders of a majority in principal amount of the notes of a series (including additional notes of such series, if any) may waive any existing Default or Event of Default under the Indenture, and its consequences, except a default in the payment of the principal of or interest on any notes of such series, as applicable.

The Holders may not enforce the Indenture or the notes of a series except as provided in the Indenture and under the TIA. Subject to the provisions of the Indenture relating to the duties of the Trustee, the Trustee is under no obligation to exercise any of its rights or powers under the Indenture at the request, order or direction of any of the Holders, unless such Holders have offered to the Trustee security or indemnity reasonably satisfactory to it. Subject to all provisions of the Indenture and applicable law, the Holders of a majority in aggregate principal amount of a series of notes then outstanding 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, subject to the Trustee receiving security or indemnity reasonably satisfactory to it. Nothing herein shall impair the right of a Holder to institute suit for the enforcement of any payment on or with respect to the notes.

We will be required to provide an officer’s certificate to the Trustee promptly upon obtaining knowledge of any Default or Event of Default (provided that we shall provide an officer’s certificate annually as to whether or not such officer knows of any Default or Event of Default) that has occurred and, if applicable, the officer’s certificate shall describe such Default or Event of Default and the status thereof.

No personal liability of directors, officers, employees, incorporator and stockholders

No past, present or future director, officer, employee, incorporator, agent, stockholder or affiliate of us or any of our Subsidiaries, as such, shall have any liability for any obligations of us or any of our Subsidiaries under the notes or the Indenture or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder of notes by accepting a note waives and releases all such liability. This waiver and release are part of the consideration for issuance of the notes.

Legal defeasance and covenant defeasance

We may, at our option and at any time, elect to have our obligations discharged with respect to the outstanding notes of a series (“Legal Defeasance”). Such Legal Defeasance means that we shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding notes of a series, except for:

(1) the rights of Holders to receive payments in respect of the principal of, premium, if any, and interest on the notes of such series when such payments are due;

(2) our obligations with respect to the notes of such series concerning issuing temporary notes, registration of notes, mutilated, destroyed, lost or stolen notes and the maintenance of an office or agency for payments;

S-22

(3) the rights, powers, trusts, duties and immunities of the Trustee and our obligations in connection therewith; and

(4) the Legal Defeasance provisions of the Indenture.

In addition, we may, at our option and at any time, elect to have our obligations released with respect to certain covenants that are described in the Indenture, including those described under “—Certain covenants—Limitation on liens,” “—Certain covenants—Limitation on sale and lease-back transactions” and “—Repurchase upon change of control triggering event” (“Covenant Defeasance”), and thereafter any omission to comply with such obligations shall not constitute a Default or Event of Default with respect to the notes of a series. In the event Covenant Defeasance occurs, certain events (not including non-payment, bankruptcy, receivership, reorganization and insolvency events) described under “—Events of default” will no longer constitute an Event of Default with respect to the notes of the applicable series.

In order to exercise either Legal Defeasance or Covenant Defeasance with respect to the notes of a series:

(1) we must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders cash in U.S. dollars, non-callable U.S. government obligations or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and interest on the notes of such series on the stated date for payment thereof or on the applicable redemption date, as the case may be;

(2) in the case of Legal Defeasance, we must deliver to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that:

(a) we have received from, or there has been published by, the Internal Revenue Service a ruling; or

(b) since the date of the Indenture, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon such opinion of counsel shall confirm that, the beneficial owners of the applicable series of notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred;

(3) in the case of Covenant Defeasance, we must deliver to the Trustee an opinion of counsel in the United States reasonably acceptable to the Trustee confirming that the beneficial owners of the applicable series of notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred;

(4) no Default or Event of Default shall have occurred and be continuing with respect to such series of notes on the date of such deposit (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings);

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Indenture with respect to such series of notes (other than a Default or an Event of Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings) or any other material agreement or instrument to which we or any of our Subsidiaries is a party or by which we or any of our Subsidiaries is bound;

(6) we must deliver to the Trustee an officer’s certificate and an opinion of counsel, each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance with respect to such series of notes have been complied with;

S-23

(7) we must deliver to the Trustee an opinion of counsel to the effect that assuming no intervening bankruptcy of us between the date of deposit and the 91st day following the date of deposit and that no Holder is an insider of us, after the 91st day following the date of deposit, the trust funds will not be subject to the effect of any applicable bankruptcy, insolvency, reorganization or similar laws affecting creditors’ rights generally; and

(8) certain other customary conditions precedent are satisfied.

Satisfaction and discharge

The Indenture will be discharged and will cease to be of further effect (except as to surviving rights or registration of transfer or exchange of the notes, as expressly provided for in the Indenture) as to all outstanding notes of a series, when:

(1) either:

(a) all notes of that series theretofore authenticated and delivered (except destroyed, lost, or stolen notes and which have been replaced or paid and notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by us and thereafter repaid to us or discharged from such trust) have been delivered to the Trustee for cancellation; or

(b) all notes of that series not theretofore delivered to the Trustee for cancellation (1) have become due and payable, (2) will become due and payable within one year, or (3) are to be called for redemption within one year, under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of us, and we have irrevocably deposited or caused to be deposited with the Trustee funds in an amount sufficient to pay and discharge the entire Indebtedness on the notes of that series not theretofore delivered to the Trustee for cancellation, for principal of, premium, if any, and interest on the notes of that series to the date of deposit together with irrevocable instructions from us directing the Trustee to apply such funds to the payment thereof at the stated maturity or redemption, as the case may be;

(2) we have paid all other sums payable under the Indenture by us; and

(3) we have delivered to the Trustee an officer’s certificate and an opinion of counsel stating that all conditions precedent under the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

Modification of the Indenture

From time to time, we and the Trustee, without the consent of the Holders, may amend the Indenture and the notes of a series for certain specified purposes, including:

(1) to cure any ambiguity, defect or inconsistency;

(2) to provide for uncertificated notes of that series in addition to or in place of certificated notes;

(3) to comply with the provisions described under “—Certain covenants—Limitation on mergers and other transactions”;

(4) to comply with the requirements of the SEC in order to effect or maintain the qualification of the Indenture under the TIA;

(5) to evidence and provide for the acceptance of appointment by a successor Trustee;

S-24

(6) to conform the text of the Indenture or the notes of that series to any corresponding provision of this “Description of Notes”;

(7) to establish the form or terms of notes of any series as permitted by the terms of the Indenture;

(8) to provide for the assumption by a successor corporation, partnership, trust or limited liability company of our obligations under the Indenture, in each case in compliance with the provisions thereof; or

(9) to make any change that would provide any additional rights or benefits to the Holders of the notes of a series (including to secure the notes of that series, add guarantees with respect thereto, to add to our covenants for the benefit of the Holders of that series or to surrender any right or power conferred upon us under the Indenture) or that does not adversely affect the legal rights hereunder of any Holder of the notes in any material respect.

In formulating its opinion on such matters, the Trustee will be entitled to rely on such evidence as it deems appropriate, including, without limitation, solely on an opinion of counsel or an officer’s certificate or both. Other modifications and amendments of the Indenture may be made with the consent of the Holders of a majority in principal amount of the then outstanding notes of each series affected (including additional notes, if any), except that, without the consent of each Holder affected thereby, no amendment may:

(1) reduce the principal amount of notes whose Holders must consent to an amendment;

(2) reduce the rate of, change or have the effect of changing the time for payment of interest, including defaulted interest, on any notes;

(3) reduce the principal of, change or have the effect of changing the fixed maturity of any notes, change the date on which any notes may be subject to redemption or repurchase or reduce the redemption price or repurchase price therefor;

(4) make any notes payable in currency other than that stated in the notes or change the place of payment of the notes from that stated in the notes or in the Indenture;

(5) make any change in provisions of the Indenture protecting the right of each Holder to receive payment of principal of and interest on such note on or after the due date thereof or to bring suit to enforce such payment, or permitting Holders of a majority in principal amount of notes (including additional notes of that series, if any) to waive Defaults or Events of Default;

(6) make any change in these amendment and waiver provisions; or

(7) make any change to or modify the ranking of the notes of a series that would adversely affect the Holders of that series.

Governing law

The Indenture will provide that it and the notes will be governed by, and construed in accordance with, the laws of the State of New York.

The Trustee

The Indenture will provide that, except during the continuance of an Event of Default, the Trustee will perform only such duties as are specifically set forth in the Indenture. During the existence of an Event of Default, the Trustee will exercise such rights and powers vested in it by the Indenture, and use the same degree of care and skill in its exercise as a prudent person would exercise or use under the circumstances in the conduct of its own affairs.

S-25

The Indenture and the provisions of the TIA contain certain limitations on the rights of the Trustee, should it become a creditor of us, to obtain payments of claims in certain cases or to realize on certain property received in respect of any such claim as security or otherwise. Subject to the TIA, the Trustee will be permitted to engage in other transactions; provided that, if the Trustee acquires any conflicting interest as described in the TIA, it must eliminate such conflict or resign.

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

The Treasury Rate shall be determined by us 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 applicable 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, we shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the applicable 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 applicable redemption date.

If on the third Business Day preceding the applicable redemption date H.15 TCM is no longer published, we 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, as applicable. 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, we 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, we 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.

Book-entry settlement

We will issue the notes of each series in the form of one or more permanent global notes in definitive, fully registered, book-entry form. The global notes will be deposited with or on behalf of DTC and registered in the name of Cede & Co., as nominee of DTC, or will remain in the custody of the Trustee in accordance with arrangements between DTC and the Trustee.

S-28

If you wish to hold notes through the DTC system, you must either be a direct participant in DTC or hold through a direct participant in DTC. Direct participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations that have accounts with DTC. For those holders of notes outside the United States, Euroclear and Clearstream (both described below) participate in DTC through their New York depositaries. Indirect participants are securities brokers and dealers, banks and trust companies that do not have an account with DTC, but that clear through or maintain a custodial relationship with a direct participant. Thus, indirect participants have access to the DTC system through direct participants or through other indirect participants that have access through direct participants.

DTC may grant proxies or authorize its participants (or persons holding beneficial interests in the global notes through these participants) to exercise any rights of a holder or take any other actions that a holder is entitled to take under the Indenture or the notes. The ability of Euroclear or Clearstream to take actions as a holder of the notes under the Indenture will be limited by the ability of their respective depositaries to carry out such actions for them through DTC. Euroclear and Clearstream will take such actions only in accordance with their respective rules and procedures.

The information in this section concerning DTC, Euroclear and Clearstream and their book-entry systems has been obtained from sources we believe to be reliable, but we make no representation or warranty with respect to this information. DTC, Euroclear and Clearstream are under no obligation to perform or continue to perform the procedures described below, and they may modify or discontinue them at any time. We and the Trustee will not be responsible for DTC’s, Euroclear’s or Clearstream’s performance of their obligations under their rules and procedures, or for the performance by direct or indirect participants of their obligations under the rules and procedures of the clearance systems.

Transfers within DTC, Euroclear and Clearstream will be in accordance with the usual rules and operating procedures of the relevant system. Cross-market transfers between investors who hold or who will hold any notes through DTC and investors who hold or will hold any notes through Euroclear or Clearstream will be effected in DTC through the respective depositaries of Euroclear and Clearstream.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the Indenture and under the notes. Except as provided below, owners of beneficial interests in a global note will not be entitled to have notes represented by that global note registered in their names, will not receive or be entitled to receive physical delivery of certificated notes and will not be considered the owners or holders thereof under the Indenture or under the notes for any purpose, including with respect to the giving of any direction, instruction or approval to the Trustee. Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a direct or indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of notes of the applicable series under the Indenture or a global note representing the notes of that series.

Neither we nor the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of the notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the notes.

Payments on the notes represented by global notes will be made to DTC or its nominee, as the case may be, as the registered owner thereof. We expect that DTC or its nominee, upon receipt of any payment on the notes represented by a global note, will credit participants’ accounts with payments in amounts proportionate to their respective beneficial interests in the global note as shown in the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in global notes held through such participants will be governed by standing instructions and customary practice as is now the case with notes held for the accounts of customers registered in the names of nominees for such customers. The participants will be responsible for those payments.

S-29

The laws of some states require certain purchasers of notes to take physical delivery of the notes in definitive form. These laws may impair your ability to transfer beneficial interests in global notes to such purchasers. DTC can act only on behalf of its direct participants, who in turn act on behalf of indirect participants and certain banks. Thus, your ability to pledge a beneficial interest in a global note to persons that do not participate in the DTC system, and to take other actions, may be limited because you will not possess a physical certificate that represents your interest.

The Depository Trust Company

DTC has advised us as follows:

Transfers between participants in DTC will be effected in accordance with DTC’s procedures, and will be settled in same-day funds. Transfers between participants in Euroclear and Clearstream will be effected in accordance with their respective rules and operating procedures. Subject to compliance with the transfer restrictions applicable to the notes described herein, cross-market transfers between the participants in DTC, on the one hand, and Euroclear and Clearstream participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream, as the case may be, by its respective depositary; however, such cross-market transactions will require delivery of instructions to Euroclear or Clearstream, as the case may be, by the counterparty in such system in accordance with the rules and procedures and within the established deadlines (Brussels time) of such system. Euroclear or Clearstream, as the case may be, will, if the transaction meets its settlement requirements, deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global note in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear participants and Clearstream participants may not deliver instructions directly to the depositories for Euroclear or Clearstream.

Certificated notes

We will issue certificated notes of a series to each person that DTC identifies as the beneficial owner of the notes of that series represented by a global note upon surrender by DTC of each such global note only if:

S-30

Neither we nor the Trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the related notes. We and the Trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the notes to be issued. In connection with any proposed exchange of a certificated note for a global note, we or DTC shall be required to provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including, without limitation, any cost basis reporting obligations under Internal Revenue Code Section 6045. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

S-31

DESCRIPTION OF OTHER INDEBTEDNESS

The following descriptions are summaries of the material terms of certain indebtedness. They may not contain all the information that may be important to you. The following summaries are qualified in their entirety by reference to the relevant agreements, which are incorporated by reference herein.

Existing Notes

In November 2014, we issued $1.25 billion aggregate principal amount of our 4.650% Senior Notes due 2024 (the “Existing 2024 Notes”) and $250.0 million aggregate principal amount of our 5.650% Senior Notes due 2034 (the “Existing 2034 Notes”). In March 2019, we issued $800.0 million aggregate principal amount of our 4.100% Senior Notes due 2029 (the “Existing 2029 Notes”) and $400.0 million aggregate principal amount of our 5.000% Senior Notes due 2049 (the “Existing 2049 Notes”). In February 2020, we issued $750.0 million aggregate principal amount of our 3.300% Senior Notes due 2050 (the “Existing 2050 Notes”). In June 2022, we issued $1.0 billion aggregate principal amount of our 4.650% Senior Notes due 2032 (the “Existing 2032 Notes”), $1.2 billion aggregate principal amount of our 4.950% Senior Notes due 2052 (the “Existing 2052 Notes”) and $800.0 million aggregate principal amount of our 5.250% Senior Notes due 2062 (the “Existing 2062 Notes” and, together with the Existing 2024 Notes, the Existing 2034 Notes, the Existing 2029 Notes, the Existing 2049 Notes, the Existing 2050 Notes, the Existing 2032 Notes and the Existing 2052 Notes, the “Existing Notes”). In July 2022, we used a portion of the net proceeds of the Existing 2032 Notes, the Existing 2052 Notes and the Existing 2062 Notes to complete a tender offer for $500.0 million aggregate principal amount of the Existing 2024 Notes, including associated redemption premiums, accrued interest and other fees and expenses.

As of December 31, 2023, there was $5.95 billion in aggregate principal amount of Existing Notes outstanding.

Interest on the Existing 2024 Notes and the Existing 2034 Notes is payable semi-annually on May 1 and November 1 of each year, interest on the Existing 2029 Notes and the Existing 2049 Notes is payable semi-annually on March 15 and September 15 of each year, interest on the Existing 2050 Notes is payable semi-annually on March 1 and September 1 of each year and interest on the Existing 2032 Notes, the Existing 2052 Notes and the Existing 2062 Notes is payable semi-annually on January 15 and July 15 of each year. The Existing 2024 Notes, the Existing 2034 Notes, the Existing 2029 Notes, the Existing 2049 Notes and the Existing 2050 Notes were issued pursuant to that certain indenture dated as of November 6, 2014 (the “2014 Indenture”) between us and Wells Fargo Bank, National Association, as trustee. The Existing 2032 Notes, the Existing 2052 Notes and the Existing 2062 Notes were issued pursuant to the Indenture. Each of the 2014 Indenture and the Indenture includes covenants that limit our and certain of our subsidiaries’ ability to grant liens on specified properties or the capital stock or indebtedness of certain of our subsidiaries and enter into sale and leaseback transactions with respect to specified properties, subject to significant exceptions. As of December 31, 2023, we were in compliance with all of our covenants under each of the 2014 Indenture and the Indenture.

In certain circumstances involving a change of control followed by a downgrade of the rating of a series of Existing Notes by at least two of Moody’s, S&P and Fitch, unless we have exercised our right to redeem the Existing Notes of such series, we will be required to make an offer to repurchase all or, at the holder’s option, any part, of each holder’s Existing Notes of that series at a purchase price payable in cash equal to 101% of the aggregate principal amount of Existing Notes repurchased plus accrued and unpaid interest, if any, on the Existing Notes repurchased, up to, but not including, the date of repurchase

Credit Agreement

In June 2022, we entered into the Credit Agreement providing for a $1.5 billion five-year unsecured revolving credit facility (the “Revolving Credit Facility”). Amounts outstanding under the Credit Agreement will

S-32

be guaranteed on an unsecured basis by certain of our material domestic subsidiaries. As of December 31, 2023, we had no outstanding borrowings under the Revolving Credit Facility.

We may borrow, repay and reborrow funds under the Revolving Credit Facility until its maturity on June 8, 2027 (the “Revolving Facility Maturity Date”), at which time such Revolving Credit Facility will terminate, and all outstanding loans under such facility, together with all accrued and unpaid interest, must be repaid. We may prepay the Revolving Credit Facility at any time without a prepayment penalty.

Borrowings under the Revolving Credit Facility will bear interest, at our option, at either: (i) the Alternative Base Rate (“ABR”) plus a spread, which ranges from 0 bps to 25 bps, or (ii) the Term Secured Overnight Financing Rate, plus an adjustment increase of 10 bps (“Adjusted Term SOFR”), plus a spread, which ranges from 75 bps to 125 bps. The spreads under ABR and Adjusted Term SOFR are subject to adjustment in conjunction with credit rating downgrades or upgrades, which include certain ESG related goals and metrics. We are also obligated to pay an annual commitment fee on the daily undrawn balance of the Revolving Credit Facility, which ranges from 4.5 bps to 12.5 bps, subject to an adjustment in conjunction with changes to our credit rating. As of December 31, 2023, we elected to pay interest on the borrowed amount under the Revolving Credit Facility at Adjusted Term SOFR plus a spread of 85 bps, and the applicable commitment fee on the daily undrawn balance of the Revolving Credit Facility was 6 bps.

We are required to maintain the maximum leverage ratio as described in the Credit Agreement, on a quarterly basis of 3.50 to 1.00, covering the trailing four consecutive fiscal quarters for each fiscal quarter, which can be increased to 4.00 to 1.00 for a period of time in connection with a material acquisition or a series of material acquisitions. As of December 31, 2023, our maximum allowed leverage ratio was 3.50 to 1.00.

The Credit Agreement contains restrictive covenants that impose operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interest, including restrictions on our and our subsidiaries’ ability to (i) incur or issue subsidiary debt or preferred equity; (ii) create liens; (iii) enter into sale and leaseback transactions; (iv) enter into fundamental changes (including mergers, consolidations, transfers of all or substantially all assets and changes in nature of business conducted); and (v) create or permit certain restrictive agreements.

The Credit Agreement contains certain customary representations and warranties, affirmative covenants and events of default.

We were in compliance with all covenants under the Credit Agreement as of December 31, 2023.

S-33

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of the material U.S. federal income tax consequences of the purchase, ownership and disposition of the notes issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or foreign tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a holder of the notes. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership and disposition of the notes.

This discussion is limited to holders who hold the notes as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). In addition, this discussion is limited to persons purchasing the 20  notes for cash at original issue and at their original “issue price” within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial amount of the notes is sold to the public for cash) and persons purchasing the 2052 notes for cash in this offering and at the price set forth on the cover page of this prospectus supplement. This discussion does not address all U.S. federal income tax consequences relevant to a holder’s particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to holders subject to special rules, including, without limitation:

If an entity treated as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, partnerships holding the notes and the partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE

S-34

APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES ARISING UNDER OTHER U.S. FEDERAL TAX LAWS (INCLUDING ESTATE AND GIFT TAX LAWS), UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE TAX TREATY.

Tax consequences applicable to U.S. Holders

Definition of a U.S. Holder

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

Pre-issuance accrued interest on the 2052 notes

A portion of the price paid for the 2052 notes will be allocable to interest that “accrued” prior to the date the 2052 notes are purchased (“pre-issuance accrued interest”). We intend to take the position that, on the first payment date for the 2052 notes, a portion of the stated interest received in an amount equal to the pre-issuance accrued interest will be treated as a return of the pre-issuance accrued interest and not as a payment of interest on the 2052 notes. Amounts treated as a return of pre-issuance accrued interest should not be taxable when received and should be excluded from the holder’s adjusted tax basis in the applicable 2052 note.

Amortizable bond premium on the 2052 notes

If a U.S. Holder purchases a 2052 note for an amount (not including any amount paid for pre-issuance accrued interest) that is greater than the principal amount of the 2052 note, the U.S. Holder will be considered to have purchased the 2052 note with bond premium. The U.S. Holder generally may elect to amortize any bond premium under the constant yield method. A U.S. Holder that elects to amortize bond premium must generally use any amortizable bond premium allocable to an accrual period to offset stated interest required to be included in income with respect to the 2052 notes in such accrual period and reduce its tax basis in the 2052 notes by the amount of the premium amortized in any year. An election to amortize bond premium applies to all taxable debt obligations then owned and thereafter acquired by such U.S. Holder and such election may be revoked only with the consent of the IRS. If a U.S. Holder does not make such election, any bond premium will be included in such U.S. Holder’s tax basis in the 2052 note for purposes of computing the amount of gain or loss recognized on the taxable disposition of the note.

Market discount on the 2052 notes

If a U.S. Holder purchases a 2052 note at a price that is lower than the 2052 note’s principal amount by 0.25% or more of the principal amount, multiplied by the number of remaining whole years to maturity, the 2052 note will be considered to bear “market discount” in the U.S. Holder’s hands. In this case, any gain that the U.S. Holder realizes on the disposition of the 2052 note generally will be treated as ordinary interest income to the extent of the market discount that accrued on the 2052 note during the U.S. Holder’s holding period. In addition,

S-35

the U.S. Holder could be required to defer the deduction of a portion of the interest paid on any indebtedness that the U.S. Holder incurred or maintained to purchase or carry the 2052 note. In general, market discount will be treated as accruing ratably over the term of the 2052 note, or, at the U.S. Holder’s election, under a constant yield method.

A U.S. Holder may elect to include market discount in gross income currently as it accrues (on either a ratable or constant yield basis), in lieu of treating a portion of any gain realized on a sale of the 2052 note as ordinary income. If a U.S. Holder elects to include market discount on a current basis, the interest deduction deferral rule described above will not apply. If a U.S. Holder does make such an election, it will apply to all market discount debt instruments that the U.S. Holder acquires on or after the first day of the first taxable year to which the election applies. The election may not be revoked without the consent of the IRS.

Payments of interest

Subject to the discussion of “—Pre-issuance accrued interest on the 2052 notes” and “—Amortizable bond premium on the 2052 notes” above in the case of the 2052 notes, interest on a note generally will be taxable to a U.S. Holder as ordinary income at the time such interest is received or accrued, in accordance with such U.S. Holder’s method of tax accounting for U.S. federal income tax purposes. It is expected, and this discussion assumes, that the notes will be issued without original issue discount for U.S. federal income tax purposes.

Sale or other taxable disposition

A U.S. Holder will recognize gain or loss on the sale, exchange, redemption, retirement or other taxable disposition of a note. The amount of such gain or loss will generally equal the difference between the amount received for the note in cash or other property valued at fair market value (less amounts attributable to any accrued but unpaid interest, which, unless it represents pre-issuance accrued interest with respect to a 2052 note, will be taxable as interest to the extent not previously included in income) and the U.S. Holder’s adjusted tax basis in the note. A U.S. Holder’s adjusted tax basis in a note generally will be equal to the amount the U.S. Holder paid for the note and, in the case of a 2052 note, excluding any amount attributable to pre-issuance accrued interest with respect to the 2052 note (as described above under “—Pre-issuance accrued interest on the 2052 notes”), increased by any amounts the U.S. Holder is required to include in income with respect to the 2052 note under the rules governing market discount and decreased by the amount of amortized bond premium, if any, with respect to the 2052 note. Except as discussed above with respect to market discount, any gain or loss will be capital gain or loss, and will be long-term capital gain or loss if the U.S. Holder has held the note for more than one year at the time of sale or other taxable disposition. Otherwise, such gain or loss will be short-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. Holders, including individuals, generally will be taxable at a reduced rate. The deductibility of capital losses is subject to limitations.

Information reporting and backup withholding

A U.S. Holder may be subject to information reporting and backup withholding when such holder receives payments on a note or receives proceeds from the sale or other taxable disposition of a note (including a redemption or retirement of a note). Certain U.S. Holders are exempt from backup withholding, including corporations and certain tax-exempt organizations. A U.S. Holder will be subject to backup withholding if such holder is not otherwise exempt and:

S-36

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisors regarding their qualification for an exemption from backup withholding and the procedures for obtaining such an exemption.

Tax consequences applicable to Non-U.S. Holders

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is a beneficial owner of a note that is neither a U.S. Holder nor an entity treated as a partnership for U.S. federal income tax purposes.

Payments of interest

Interest paid on a note to a Non-U.S. Holder that is not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States generally will not be subject to U.S. federal income tax, or withholding tax of 30% (or such lower rate specified by an applicable income tax treaty), provided that:

If a Non-U.S. Holder does not satisfy the requirements above, such Non-U.S. Holder may be entitled to a reduction in or an exemption from withholding on such interest as a result of an applicable tax treaty. To claim such entitlement, the Non-U.S. Holder must provide the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) claiming a reduction in or exemption from withholding tax under the benefit of an income tax treaty between the United States and the country in which the Non-U.S. Holder resides or is established.

If interest paid to a Non-U.S. Holder is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such interest is attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that interest paid on a note is not subject to withholding tax because it is effectively connected with the conduct by the Non-U.S. Holder of a trade or business within the United States.

S-37

Any such effectively connected interest generally will be subject to U.S. federal income tax at the regular rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected interest, as adjusted for certain items.

The certifications described above must be provided to the applicable withholding agent prior to the payment of interest and must be updated periodically. Non-U.S. Holders that do not timely provide the applicable withholding agent with the required certification, but that qualify for a reduced rate under an applicable income tax treaty, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

With respect to the 2052 notes, because the applicable withholding agent may not know the portion of the first interest payment that is treated as a return of pre-issuance accrued interest, for purposes of these withholding rules the applicable withholding agent may treat the entire payment as interest. Non-U.S. Holders of the 2052 notes should consult their tax advisors regarding the possibility of claiming a refund with respect to any withholding imposed on the portion of the first interest payment made on the 2052 notes treated as a return of pre-issuance accrued interest.

Sale or other taxable disposition

A Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale, exchange, redemption, retirement or other taxable disposition of a note (such amount excludes any amount allocable to accrued and unpaid interest, which generally will be treated as interest and may be subject to the rules discussed above in “—Tax consequences applicable to Non-U.S. Holders—Payments of interest”) unless:

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates. A Non-U.S. Holder that is a foreign corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

Gain described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty), which may be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

Non-U.S. Holders should consult their tax advisors regarding any applicable income tax treaties that may provide for different rules.

Information reporting and backup withholding

Payments of interest generally will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder certifies its non-U.S. status as described above under “—Tax consequences applicable to Non-U.S. Holders—Payments of interest.” However, information returns are required to be filed with the IRS in connection with any interest paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition,

S-38

proceeds of the sale or other taxable disposition of a note (including a retirement or redemption of the note) within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the statement described above and does not have actual knowledge or reason to know that such holder is a United States person or the holder otherwise establishes an exemption. Proceeds of a disposition of a note paid outside the United States and conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional withholding tax on payments made to foreign accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on payments of interest on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, a note paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in clause (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of interest on a note. While withholding under FATCA would have applied also to payments of gross proceeds from the sale or other disposition of a note on or after January 1, 2019, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued. With respect to the 2052 notes, because the applicable withholding agent may not know the portion of the first interest payment that is treated as a return of pre-issuance accrued interest, for purposes of these withholding rules, the applicable withholding agent may treat the entire payment as interest.

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

UNDERWRITING

Citigroup Global Markets Inc., BofA Securities, Inc. and J.P. Morgan Securities LLC are representatives of each of the underwriters named below. Subject to the terms and conditions set forth in the underwriting agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters has agreed, severally and not jointly, to purchase from us, the principal amount of notes set forth opposite its name below.

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all of the notes to be sold under the underwriting agreement if any of these notes are purchased. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or, under certain circumstances, the underwriting agreement may be terminated.

We have agreed to indemnify the underwriters and their controlling persons against certain liabilities in connection with this offering, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

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 and to other conditions specified in the underwriting agreement. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

Discounts

The representatives have advised us that the underwriters propose initially to offer the notes of each series to the public at the public offering price for such series set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of  % of the principal amount of the 20  notes and  % of the principal amount of the 2052 notes. The underwriters may allow, and dealers may re-allow, a concession not in excess of  % of the principal amount of the 20     notes and  % of the principal amount of the 2052 notes to other dealers. After the initial offering, the public offering price, concession or any other term of the offering with respect to one or more series of notes may be changed.

The following table shows the underwriting discount that we will pay to the underwriters for each series of notes.

S-40

The expenses of the offering payable by us, not including the underwriting discounts set forth in the table above, are estimated at $     million. The underwriters have agreed to reimburse us for certain of our expenses in connection with the offering of the notes.

New issue of 20   notes; further issuance of 2052 notes

The 20   notes is a new issue of securities with no established trading market. The 2052 notes will be issued as additional notes of the same series as the existing 2052 notes. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that certain of the underwriters currently make a market in the existing 2052 notes and that they presently intend to make a market in each series of notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes or that an active public market for the notes will develop. If an active public trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

Short positions

In connection with the offering, the underwriters may purchase and sell the notes in the open market. These transactions may include short sales and purchases on the open market to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater principal amount of notes than they are required to purchase in the offering. The underwriters must close out any short position by purchasing notes in the open market. A short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the notes in the open market after pricing that could adversely affect investors who purchase in the offering.

Similar to other purchase transactions, the underwriters’ purchases to cover the syndicate short sales may have the effect of raising or maintaining the market price of the notes or preventing or retarding a decline in the market price of the notes. As a result, the price of the notes may be higher than the price that might otherwise exist in the open market.

Neither we nor any of the underwriters 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. In addition, neither we nor any of the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other relationships

The underwriters and affiliates are full-service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their affiliates have provided, and may in the future provide, a variety of these services to us and to persons and entities with relationships with us, for which they received or will receive customary fees and expenses. JPMorgan Chase Bank, N.A., an affiliate of J.P. Morgan Securities LLC, is the administrative agent under the Credit Agreement. In addition, certain of the underwriters or their affiliates are lenders under the Credit Agreement.

In addition, in the ordinary course of their business activities, the underwriters and 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. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates.

S-41

Certain of the underwriters or their affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such 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, 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 their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

TABLE OF CONTENTS

ABOUT THIS PROSPECTUS

This prospectus is part of an “automatic shelf” registration statement that we filed with the U.S. Securities and Exchange Commission, or the SEC, as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended (the “Securities Act”), using a “shelf” registration process. By using a shelf registration statement, we may sell securities from time to time and in one or more offerings as described in this prospectus. Each time that we offer and sell securities, we will provide a prospectus supplement to this prospectus that contains specific information about the securities being offered and sold and the specific terms of that offering. We may also authorize one or more free writing prospectuses to be provided to you that may contain material information relating to these offerings. The prospectus supplement or free writing prospectus may also add, update or change information contained in this prospectus with respect to that offering. If there is any inconsistency between the information in this prospectus and the applicable prospectus supplement or free writing prospectus, you should rely on the prospectus supplement or free writing prospectus, as applicable. Before purchasing any securities, you should carefully read both this prospectus and the applicable prospectus supplement (and any applicable free writing prospectuses), together with the additional information described under the heading “Where You Can Find More Information; Incorporation by Reference.”

We have not authorized anyone to provide you with any information or to make any representations other than those contained in this prospectus, any applicable prospectus supplement or any free writing prospectuses prepared by or on behalf of us or to which we have referred you. We take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you.

You should assume that the information appearing in this prospectus and the applicable prospectus supplement to this prospectus is accurate only as of the date on its respective cover, that the information appearing in any applicable free writing prospectus is accurate only as of the date of that free writing prospectus, and that any information incorporated by reference is accurate only as of the date of the document incorporated by reference, unless we indicate otherwise. Our business, financial condition, results of operations and prospects may have changed since those dates. This prospectus incorporates by reference, and any prospectus supplement or free writing prospectus may contain and incorporate by reference, market data and industry statistics and forecasts that are based on independent industry publications and other publicly available information. Although we believe these sources are reliable, we do not guarantee the accuracy or completeness of this information and we have not independently verified this information.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and documents that are incorporated by reference into this prospectus contain certain forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act and the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact may be forward-looking statements. You can identify these and other forward-looking statements by the use of words such as “may,” “will,” “could,” “would,” “should,” “expects,” “plans,” “anticipates,” “relies,” “believes,” “estimates,” “predicts,” “intends,” “potential,” “continues,” “thinks,” “seeks” or the negative of such terms, or other comparable terminology. Forward-looking statements also include the assumptions underlying or relating to any of the foregoing statements. These forward-looking statements are based on current information and expectations, and involve a number of risks and uncertainties. We claim the protection of the safe harbor for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 for all forward-looking statements.

Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as the future impacts of the COVID-19 pandemic; forecasts of the future results of our operations, including profitability; orders for our products and capital equipment generally; sales of semiconductors; the investments by our customers in advanced technologies and new materials; growth of revenue in the semiconductor industry, the semiconductor capital equipment industry and our business; technological trends in the semiconductor industry; future developments or trends in the global capital and financial markets; our future product offerings and product features; the success and market acceptance of new products; timing of shipment of order backlog; our future product shipments and product and service revenues; our future gross margins; our future research and development (“R&D”) expenses and selling, general and administrative expenses; international sales and operations; our ability to maintain or improve our existing competitive position; success of our product offerings; creation and funding of programs for R&D; results of our investment in leading edge technologies; the effects of hedging transactions; the effect of the sale of trade receivables and promissory notes from customers; our future effective income tax rate; our recognition of tax benefits; the effects of any audits or litigation; future payments of dividends to our stockholders; the completion of any acquisitions of third parties, or the technology or assets thereof; benefits received from any acquisitions and development of acquired technologies; sufficiency of our existing cash balance, investments, cash generated from operations and the unfunded portion of our revolving credit facility to meet our operating and working capital requirements, including debt service and payment thereof; future dividends, and stock repurchases; our compliance with the financial covenants under the credit agreement for our revolving credit facility; the adoption of new accounting pronouncements; and our repayment of our outstanding indebtedness.

Actual results may differ materially from those projected in such statements due to various factors, including but not limited to: the impact of the COVID-19 pandemic on the global economy and on our business, financial condition and results of operations, including the supply chain constraints we are experiencing as a result of the pandemic; economic, political and social conditions in the countries in which we, our customers and our suppliers operate, including global trade policies; disruption to our manufacturing facilities or other operations, or the operations of our customers, due to natural catastrophic events, health epidemics, acts of war such as Russia’s invasion of Ukraine or terrorism; ongoing changes in the technology industry, and the semiconductor industry in particular, including future growth rates, pricing trends in end-markets, or changes in customer capital spending patterns; our ability to timely develop new technologies and products that successfully anticipate or address changes in the semiconductor industry; our ability to maintain our technology advantage and protect our proprietary rights; our ability to compete with new products introduced by our competitors; our ability to attract, onboard and retain key personnel; cybersecurity threats, cyber incidents affecting us and our customers, suppliers and other service providers’ systems and networks and our and their ability to access critical information systems for daily business operations; liability to our customers under indemnification provisions if our products fail to operate properly or contain defects or our customers are sued by third parties due to our products; exposure to a highly concentrated customer base; availability and cost of the wide range of materials used in the production of our products; our ability to operate our business in accordance with our business plan;

legal, regulatory and tax environments in which we perform our operations and conduct our business and our ability to comply with relevant laws and regulations; our ability to pay interest and repay the principal of our current indebtedness is dependent upon our ability to manage our business operations, our credit rating and the ongoing interest rate environment, among other factors; instability in the global credit and financial markets; our exposure to currency exchange rate fluctuations, or declining economic conditions in those countries where we conduct our business; changes in our effective tax rate resulting from changes in the tax rates imposed by jurisdictions where our profits are determined to be earned and taxed, expiration of tax holidays in certain jurisdictions, resolution of issues arising from tax audits with various authorities or changes in tax laws or the interpretation of such tax laws; and our ability to identify suitable acquisition targets and successfully integrate and manage acquired businesses.

We also refer you to those factors discussed in “Risk Factors” included in documents that we file from time to time with the SEC, including KLA’s Annual Report on Form 10-K for the fiscal year ended June 30, 2021 and Quarterly Reports on Form 10-Q for the quarters ended September 30, 2021, December 31, 2021 and March 31, 2022, which are incorporated by reference herein.

We have no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or risks, except to the extent required by applicable securities laws. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements. New information, future events or risks could cause the forward-looking events we discuss in this prospectus not to occur. You should not place undue reliance on these forward-looking statements, which reflect our expectations only as of the date of this prospectus or as of the date of the documents incorporated by reference herein, as applicable.

THE COMPANY

KLA Corporation and its majority-owned subsidiaries (“KLA” and also referred to as “we,” “our,” “us,” or similar references) is a global leader in process control and a supplier of process-enabling solutions for a broad range of industries, including semiconductors, printed circuit boards (“PCB”) and displays. We provide solutions for manufacturing and testing wafers and reticles, integrated circuits (“IC” or “chip”), packaging, light-emitting diodes, power devices, compound semiconductor devices, microelectromechanical systems (“MEMS”), data storage, PCBs, flat and flexible panel displays, and general materials research, as well as providing contracted and comprehensive installation and maintenance services across our installed base.

On February 20, 2019, we completed the acquisition of Orbotech, Ltd., a global supplier of yield-enhancing and process-enabling solutions for the manufacture of electronics products, in order to target growth opportunities in new and expanding end markets. We transformed our organizational structure into four reportable segments: Semiconductor Process Control; Specialty Semiconductor Process; PCB, Display and Component Inspection; and Other.

Within the Semiconductor Process Control segment, our comprehensive portfolio of inspection, metrology and data analytics products, and related services, help integrated circuit manufacturers achieve target yield throughout the entire semiconductor fabrication process, from research and development to final volume production. Our portfolio of differentiated products and services are designed to provide comprehensive solutions to help customers accelerate development and production ramp cycles, achieve higher and more stable semiconductor die yields and improve their overall profitability.

In the Specialty Semiconductor Process segment, we develop and sell advanced vacuum deposition and etching process tools, which are used by a broad range of specialty semiconductor customers, including manufacturers of MEMS, radio frequency communication semiconductors, and power semiconductors for automotive and industrial applications.

In the PCB, Display and Component Inspection segment, we enable electronic device manufacturers to inspect, test and measure PCBs, flat panel displays and ICs to verify their quality, deposit a pattern of desired electronic circuitry on the relevant substrate and perform three-dimensional shaping of metalized circuits on multiple surfaces.

KLA’s suite of advanced products, coupled with its unique yield management software and services, allow us to deliver the solutions our semiconductor, PCB and display customers need to achieve their productivity goals by significantly reducing their risks and costs and improving their overall profitability and return on investment.

We were formed as KLA-Tencor in April 1997 through the merger of KLA Instruments Corporation and Tencor Instruments, two long-time leaders in the semiconductor capital equipment industry that began operations in 1975 and 1976, respectively. We filed our certificate of incorporation with the Secretary of State of Delaware on July 9, 1975.

Our principal executive offices are located at One Technology Drive, Milpitas, California 95035, and our telephone number is (408) 875-3000.
