SUMMARY

The following summary highlights information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus. It does not contain all of the information that you should consider before investing in the notes. You should carefully read this entire prospectus supplement, as well as the accompanying prospectus and the documents incorporated by reference in this prospectus supplement and the accompanying prospectus and any applicable free writing prospectus prior to making your investment decision.

The Company

Workday is a leading provider of enterprise cloud applications for finance and human resources, helping customers adapt and thrive in a changing world. Workday provides more than 9,500 organizations with software-as-a-service solutions deployed in over 175 countries to help solve some of today’s most complex business challenges, including supporting and empowering their workforce, managing their finances and spend in an ever-changing environment, and planning for the unexpected.

Our purpose is to inspire a brighter work day for all. We strive to make the world of work and business better, and hope to empower customers to do the same through an innovative suite of solutions adopted by thousands of organizations around the world and across industries — from medium-sized businesses to more than 50% of the Fortune 500. Workday serves over 4,100 core Workday Financial Management and Human Capital Management (“HCM”) customers and our customers represent 25% of the Global 2000.

Central to our purpose is a set of core values — with our employees as number one — followed by customer service, innovation, integrity, fun, and profitability. We believe that having happy employees leads to happy customers, and we are committed to helping our customers drive their digital transformations in this increasingly dynamic business environment.

Workday’s suite of enterprise cloud applications addresses the evolving needs of the chief financial officer (“CFO”), chief human resources officer (“CHRO”), and chief information officer (“CIO”) across various industries. Workday applications for Financial Management, Spend Management, HCM, Planning, and Analytics and Benchmarking can also be extended to other applications and environments through the Workday Cloud Platform. Workday addresses a large market which we believe is expanding due to market growth and new product expansion. As of 2021, the global market for our human capital management software applications and financial management software applications totaled $38 billion and $67 billion, respectively, growing from a global market of $39 billion in 2011 as we innovated on our solutions and opened up new markets through strategic acquisitions. As Workday’s penetration is less than 10% and 5% in the global markets for human capital and financial management software applications, respectively, we believe Workday has an opportunity for growth as we continue to expand our presence and build on our relationships with existing customers.

We sell our subscription contracts and related services globally, primarily through our direct sales organization, which consists of field sales and field sales support personnel. The Workday Field Sales team is aligned by geography, industry, and/or prospect size. We generate customer leads, accelerate sales opportunities, and build brand awareness through our marketing programs and strategic relationships. Our marketing programs target senior business leaders, including CFOs, CHROs, and CIOs.

As a core part of our sales and marketing strategy, we have developed a global ecosystem of partners to both broaden and complement our application offerings and to provide services that are outside of our area of focus. These relationships include software and technology partners, consulting and deployment service providers, business process outsourcing partners, and software partners of Workday Ventures, our strategic investment arm, who all help enable Workday to address the challenges our customers face while focusing on executing against our strategy.

Workday’s business model also employs a “land and expand” sales strategy that focuses on efficiently acquiring new customers and growing our relationships with existing customers over time. Due to their established market presence, some of our applications have a high rate of purchase. The adoption rate of our other solutions are less mature but growing and have a large potential opportunity to expand. Our increased focus on cross-selling solutions to capture opportunity in our existing customer base has resulted in

S-6

an increase in the share of new annual contract bookings related to existing customers from approximately 20% in 2019 to approximately 40% in 2021.

As organizations adapt to changing conditions, we believe the need for an intuitive, scalable, and secure platform that ties finance, people, suppliers, and plans together in one version of truth is more important than ever. Workday provides organizations with a unified system that can help them plan, execute, analyze, and extend to other applications and environments, thereby helping them continuously adapt how they manage their business and operations. To support this, Workday delivers weekly product updates in addition to major feature releases twice a year. Through this model, Workday customers are able to stay current as one Workday community all on the same version of software that features a unified data and security model and rich user experience. We also offer professional services, both directly and through our Workday Services Partners, to help customers deploy our solutions and continually adopt new capabilities.

We were incorporated in March 2005 in Nevada, and in June 2012, we reincorporated in Delaware. Our principal executive offices are located at 6110 Stoneridge Mall Road, Pleasanton, California 94588, and our telephone number is (877) WORKDAY.

Ranking

The notes will be our senior unsecured obligations and will rank equally with all of our existing and future unsecured and unsubordinated indebtedness from time to time outstanding.

As of January 31, 2022, we had approximately $1.8 billion of outstanding indebtedness for borrowed money and approximately $6.0 billion of total liabilities on a consolidated basis, none of which was secured indebtedness. Of this amount, our subsidiaries had approximately $1.2 billion of liabilities (including trade payables and deferred revenue but excluding intercompany liabilities and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with generally accepted accounting principles) to which the notes would have been structurally subordinated.

Optional Redemption

Prior to their respective Par Call Dates (as defined in “Description of Notes — Optional Redemption”), we may redeem the notes of such 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:

•

(a) the sum of the present values of the remaining scheduled payments of principal and interest on such notes discounted to the redemption date (assuming that such 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 in “Description of Notes — Optional Redemption”) plus       basis points with respect to the 20   notes,       basis points with respect to the 20   notes and        basis points with respect to the 20   notes, in each case, less (b) interest accrued to the date of redemption; and

•

100% of the principal amount of such notes to be redeemed,

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

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

Purchase Upon Change of Control Triggering Event

If a Change of Control Triggering Event (as defined below in “Description of Notes — Purchase Upon Change of Control Triggering Event”) occurs with respect to a series of notes, unless we have exercised our right to redeem such notes as described above, we will be required to make an offer to each holder of such notes to purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder’s applicable notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that after giving effect to the purchase, any notes that remain outstanding shall have a minimum denomination of $2,000 and integral multiples of $1,000 above that amount. See “Description of Notes — Purchase Upon Change of Control Triggering Event” for more information.

Certain Covenants

The indenture governing the notes contains covenants limiting our ability and the ability of our restricted subsidiaries (as defined therein) to create certain liens and enter into certain sale leaseback transactions.

Trading

The notes do not have an established trading market. We do not intend to apply for listing of the notes on any securities exchange. The underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so and may discontinue market-making at any time without notice. See “Underwriting (Conflicts of Interest)” in this prospectus supplement for

S-9

more information about possible market-making by the underwriters.

Trustee, Registrar and Paying Agent

U.S. Bank Trust Company, National Association.

Form and Denomination

The notes of each series will be issued in the form of one or more fully registered global notes without interest coupons which will be deposited with, or on behalf of, The Depository Trust Company (“DTC”), New York, New York, and registered in the name of Cede & Co., as nominee of DTC, for the accounts of participants in DTC. Unless and until exchanged, in whole or in part, for notes in definitive registered form, a global note may not be transferred except in the limited circumstances described under “Description of Notes — Book-Entry; Delivery and Form; Global Note,” notes in certificated form will not be issued or exchanged for interests in global securities.

Governing Law

New York.

Further Issuances

We may, without the consent of the holders, increase the principal amount of each series of notes by issuing additional notes in the future on the same terms and conditions as the outstanding notes of such series, except for any differences in the issue date, the issue price, the payment of interest accrued prior to the issue date of the additional notes and the first payment of interest following the issue date of such additional notes; provided that if the additional notes are not fungible with the applicable series of notes offered hereby for U.S. federal income tax purposes, such additional notes will have one or more separate CUSIP numbers. Under the indenture, the notes and any additional notes that we may issue will be treated as a single series with the outstanding notes of such series for all purposes under the indenture (except as set forth in the immediately preceding sentence), including for purposes of determining whether the required percentage of the holders of record has given approval or consent to an amendment or waiver or joined in directing the trustee to take certain actions on behalf of all holders.

Sinking Fund

None.

Use of Proceeds

We estimate that the net proceeds from this offering will be approximately $      billion, after deducting the underwriting discount and estimated offering expenses payable by us. We intend to use the net proceeds to us from the sale of the securities offered hereby for general corporate purposes, which includes repaying an aggregate principal amount of $693.8 million outstanding under our existing senior unsecured term loan facility, and which may include repaying the $1.15 billion outstanding principal amount of our 0.25% Convertible Senior Notes due 2022. See “Use of Proceeds.”

S-10

Conflicts of Interest

We plan to use a portion of the net proceeds from this offering to repay outstanding borrowings under our Term Loan. Bank of America, N.A., Morgan Stanley Bank, N.A. and Wells Fargo Bank, National Association are each lenders under our Term Loan and are each affiliates of BofA Securities, Inc., Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC, respectively. In addition, certain of the underwriters or their affiliates may own our 0.25% Convertible Senior Notes due 2022 that we may purchase, redeem or repay with a portion of the net proceeds of this offering. In the event that any of these underwriters, together with their respective affiliates, receives at least 5% of the net proceeds of this offering, such underwriters will be deemed to have a “conflict of interest” within the meaning of FINRA Rule 5121. However, in accordance with FINRA Rule 5121, no “qualified independent underwriter” is required because the notes are investment grade-rated by one or more nationally recognized statistical rating agencies. See “Underwriting (Conflicts of Interest) — Conflicts of Interest.”

Risk Factors

Investing in our securities involves significant risks. See “Risk Factors,” beginning on page S-13, as well as the other information included in or incorporated by reference in this prospectus supplement and the accompanying prospectus, for a discussion of risks you should carefully consider before investing in our securities.

RISK FACTORS

Investing in the notes involves risks. Before making a decision to invest in the notes, you should carefully consider the risks related to the notes set forth below, as well as the risk factors related to our business and operations described in Part I, Item 1A of our most recent Annual Report on Form 10-K under the heading “Risk Factors” which are incorporated by reference in this prospectus supplement and the accompanying prospectus. See “Where You Can Find More Information” in this prospectus supplement and the accompanying prospectus.

Risks Related to the Notes

An active trading market for the notes may not develop.

There is currently no public market for the notes, and we do not currently plan to list the notes on any national securities exchange. In addition, the liquidity of any trading market in a series of notes, and the market price quoted for such notes, may be adversely affected by changes in the overall market for these notes, prevailing interest rates, ratings assigned to the notes, time remaining to the maturity of the notes, outstanding amount of the notes, the market for similar securities, prospects for other companies in our industry and changes in our consolidated financial condition, results of operations or prospects. In particular, an increase in prevailing interest rates will generally result in a decrease in the market price of the notes. A liquid trading market in the notes may not develop, which could decrease the amounts you would otherwise receive upon a sale or disposition of the notes.

The notes are our unsecured obligations and not obligations of our subsidiaries and will be structurally subordinated to the claims of our subsidiaries’ creditors. Structural subordination increases the risk that we will be unable to meet our obligations on the notes when they mature.

The notes are exclusively our obligations and are not obligations of our subsidiaries. While substantially all of our revenue-generating activity is conducted by us, to the extent in the future we conduct a substantial portion of our operations through, or a substantial portion of our assets are held by, our subsidiaries, our cash flow and ability to service our debt, including the notes, could depend upon the earnings of our subsidiaries and the distribution to us of earnings, loans or other payments by our subsidiaries.

Our subsidiaries are separate and distinct legal entities. Our subsidiaries will not guarantee the notes and are under no obligation to pay any amounts due on the notes or to provide us with funds for our payment obligations, whether by dividends, distributions, loans or other payments. Payments to us by our subsidiaries will also be contingent upon such subsidiaries’ earnings and business considerations and may be subject to legal and contractual restrictions. As of January 31, 2022, we had approximately $1.8 billion of outstanding indebtedness for borrowed money and approximately $6.0 billion of total liabilities on a consolidated basis. Of this amount, our subsidiaries had approximately $1.2 billion of liabilities (including trade payables and deferred revenue but excluding intercompany liabilities and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with generally accepted accounting principles) to which the notes will be structurally subordinated.

Our right to receive any assets of any of our subsidiaries upon their liquidation or reorganization, and therefore the right of the holders of the notes to participate in those assets, will be structurally subordinated to the claims of that subsidiary’s creditors, including its senior and subordinated debt holders and bank and trade creditors. In addition, even if we were a creditor of any of our subsidiaries, our rights as a creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us.

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 that we may incur. Accordingly, the notes will be effectively subordinated if we have, or will obtain secured borrowings to the extent of the value of the assets securing such indebtedness. The indenture governing the notes does not limit the amount of additional debt that we or our subsidiaries may incur, only restricts us, and our restricted subsidiaries, to incur secured debt with respect to principal properties (as defined in “Description of Notes — Certain Covenants”) and provides a number of exceptions to that restriction, and

S-13

permits our unrestricted subsidiaries to incur secured debt without restriction. 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 other indebtedness will be available to pay obligations on the notes only after all other such debt secured by those assets has been repaid in full. Any remaining assets will be available to you ratably with all of our other unsecured and unsubordinated creditors, including trade creditors. If there are not sufficient assets remaining to pay all of these creditors, then all or a portion of the notes then outstanding would remain unpaid.

We have substantial indebtedness which may adversely affect our financial condition and operating results.

In September 2017, we completed an offering of $1.15 billion of our 0.25% Convertible Senior Notes due 2022. As a result of this offering, we incurred $1.15 billion principal amount of indebtedness, which we may be required to pay at maturity in 2022, or upon the occurrence of a fundamental change (as defined in the Indenture by and between us and Wells Fargo Bank, National Association, as Trustee. In addition, in April 2020, we entered into a credit agreement (“Credit Agreement”) that provided for a term loan in an aggregate original principal amount of $750 million (“Term Loan”) and a revolving credit facility in an aggregate principal amount of $750 million (“Revolving Credit Facility”). As of January 31, 2022 the Term Loan had a carrying value of $692.4 million and there were no outstanding borrowings under the Revolving Credit Facility.

We may incur substantial additional debt in the future, some of which may be secured debt. There can be no assurance that we will be able to repay this indebtedness when due, or that we will be able to refinance this indebtedness on acceptable terms or at all. Our ability to pay cash upon conversion or repurchase of the 0.25% Convertible Senior Notes due 2022 may be limited by law, regulatory authority, or agreements governing our future indebtedness and is dependent on our future performance, which is subject to economic, financial, competitive, and other factors beyond our control. Any future debt may also contain limitations on our ability to pay cash upon a conversion request or repurchase upon a fundamental change.

In addition, our indebtedness could, among other things:

•

make it difficult for us to pay other obligations, including the notes;

•

make it difficult to obtain favorable terms for any necessary future financing for working capital, capital expenditures, debt service requirements, or other purposes;

•

adversely affect our liquidity and result in a material adverse effect on our financial position upon repayment of the indebtedness;

•

require us to dedicate a substantial portion of our cash flow from operations to service and repay the indebtedness, reducing the amount of cash flow available for other purposes;

•

limit our flexibility in planning for and reacting to changes in our business; and

•

negatively impact our credit rating, which could limit our ability to obtain additional financing in the future and adversely affect our business.

Our Credit Agreement also imposes restrictions on us and requires us to maintain compliance with specified covenants, including a specific leverage ratio. Our ability to comply with these covenants may be affected by events beyond our control. If we breach any of the covenants and do not obtain a waiver from the lenders, then, subject to applicable cure periods, any outstanding indebtedness may be declared immediately due and payable. Any required repayment of our debt under the Credit Agreement as a result of a fundamental change or other acceleration would lower our current cash on hand such that we would not have those funds available for use in our business.

The indenture governing the notes contains only very limited negative covenants. The limitation on liens and sale/​leaseback covenants do not apply to all our subsidiaries and contain exceptions that would allow us and our subsidiaries to grant liens or security interests with respect to their assets, rendering the holders of the notes effectively, structurally or contractually subordinated to new lenders. The indenture governing the notes does not contain any financial covenants.

The indenture governing the notes contains only very limited negative covenants. The limitation on liens and limitation on sale/leaseback covenants apply to us and to our restricted subsidiaries with respect

S-14

to principal properties of ours or such subsidiaries. As a result, these covenants do not cover the majority of our consolidated assets and our unrestricted subsidiaries will not be restricted under the indenture from granting liens or security interests with respect to all or any of their assets without having to provide similar liens or security to the holders of the notes, or from entering into sale/leaseback transactions. Exceptions within the limitation on liens covenant would allow us and our restricted subsidiaries to borrow substantial additional amounts, and to grant liens or security interests in connection with those borrowings. The indenture governing the notes does not contain any financial covenants.

Increased leverage may harm our financial condition and results of operations.

On an as adjusted basis after giving effect to this offering, as of January 31, 2022, we would have had approximately $      of total long-term indebtedness (including the notes offered hereby and the 0.25% Convertible Senior Notes due 2022), all of which would have been unsecured and unsubordinated.

We and our subsidiaries may incur additional indebtedness in the future and the notes do not restrict the future incurrence of indebtedness. Any increase in our level of indebtedness will have several important effects on our future operations, including, without limitation:

•

we and/or our subsidiaries will have additional cash requirements in order to support the payment of interest on our outstanding indebtedness;

•

increases in our outstanding indebtedness and leverage will increase our vulnerability to adverse changes in general economic and industry conditions, as well as to competitive pressure; and

•

our ability to obtain additional financing for working capital, capital expenditures, general corporate and other purposes may be limited. Our ability to make payments of principal and interest on our indebtedness depends upon our future performance, which will be subject to general economic conditions, industry cycles and financial, business and other factors affecting our consolidated operations, many of which are beyond our control.

If we are unable to generate sufficient cash flow from operations in the future to service our debt, we may be required, among other things, to:

•

seek additional financing in the debt or equity markets;

•

refinance or restructure all or a portion of our indebtedness, including the notes;

•

sell selected assets;

•

reduce or delay planned capital expenditures; or

•

reduce or delay planned operating and investment expenditures.

Such measures might not be sufficient to enable us to service our debt. In addition, any such financing, refinancing or sale of assets might not be available on economically favorable terms, or at all.

The terms of the notes will not protect you in the event of highly leveraged transactions or a change of control.

The terms of the notes will not afford you protection in the event of certain highly leveraged transactions or a change of control that may adversely affect you unless such change of control also constitutes 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 rating or otherwise adversely affect the holders of the notes. If any such transaction were to occur, the value of your notes could decline.

We may not be able to purchase 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 purchase the notes of each series upon the occurrence of a Change of Control Triggering Event with respect to such notes as provided in the indenture governing the notes. However, we may not have sufficient funds to purchase the notes in cash at such time. In addition, our ability to purchase the notes for cash may be limited by law or the terms of other agreements relating to our

S-15

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 other indebtedness and we may not have sufficient funds to repay such other indebtedness. Our failure to make such a purchase would result in a default under your notes and may cause the acceleration of our other debt.

You may not be able to determine when a Change of Control Triggering Event has occurred.

The definition of change of control, which is a condition precedent to a Change of Control Triggering Event, includes a phrase relating to the sale, lease or transfer of “all or substantially all” of our assets. There is no precisely established definition of the phrase “substantially all” under applicable law. Accordingly, your ability to require us to repurchase your notes as a result of a sale, lease or transfer of less than all of our assets to another individual, group or entity may be uncertain.

Credit ratings of the notes may change and affect the market price and marketability of the notes.

Credit ratings 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 is 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. It is also possible that such ratings may be lowered in connection with future events. Holders of notes will have no recourse against us or any other parties in the event of a change in or suspension or withdrawal of such ratings. Any lowering, suspension or withdrawal of such ratings may have an adverse effect on the market price or marketability of the notes. In addition, any decline in the ratings of the notes may make it more difficult for us to raise capital on acceptable terms.

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 decline in value. Consequently, if you purchase the Notes, and the market interest rates subsequently increase, the market value of your Notes may decline. We cannot predict the future level of market interest rates.

Redemption prior to maturity may adversely affect your return on the notes.

Since the notes are redeemable at our option, we may choose to redeem your notes at times when prevailing interest rates are relatively low. As a result, you generally will not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on your notes being redeemed.

S-16

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $     billion, after deducting the underwriting discount and estimated offering expenses payable by us. We intend to use the net proceeds to us from the sale of the securities offered hereby for general corporate purposes, which includes repaying an aggregate principal amount of $693.8 million outstanding under our existing senior unsecured term loan facility, and which may include repaying the $1.15 billion outstanding principal amount of our 0.25% Convertible Senior Notes due 2022. As of January 31, 2022, and 2021, the Term Loan had a carrying value of $692.4 million and $729.4 million, respectively, and there were no outstanding borrowings under the Revolving Credit Facility. The interest rate on the Term Loan was 1.30% and 1.38% as of January 31, 2022, and 2021, respectively. General corporate purposes may also include additions to working capital, financing of capital expenditures, share repurchases, and future acquisitions and strategic investment opportunities. Pending other uses, we intend to invest the net proceeds to us in investment-grade, interest-bearing securities such as money market funds, certificates of deposit, corporate debt, direct or guaranteed obligations of the U.S. government, term deposits, or hold as cash.

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 use funds to reduce outstanding short-term borrowings.

We plan to use a portion of the net proceeds from this offering to repay outstanding borrowings under our Term Loan. Bank of America, N.A., Morgan Stanley Bank, N.A. and Wells Fargo Bank, National Association are each lenders under our Term Loan and are each affiliates of BofA Securities, Inc., Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC, respectively. In addition, certain of the underwriters or their affiliates may own our 0.25% Convertible Senior Notes due 2022 that we may purchase, redeem or repay with a portion of the net proceeds of this offering. In the event that any of these underwriters, together with their respective affiliates, receives at least 5% of the net proceeds of this offering, such underwriters will be deemed to have a “conflict of interest” within the meaning of FINRA Rule 5121. However, in accordance with FINRA Rule 5121, no “qualified independent underwriter” is required because the notes are investment grade-rated by one or more nationally recognized statistical rating agencies. See “Underwriting (Conflicts of Interest) — Conflicts of Interest.”

In addition to our Term Loan, we have a senior unsecured revolving credit facility that currently provides for up to $750 million of revolving credit loans, matures on April 2, 2025, and provides that we may request an increase in aggregate revolving commitments of up to $250 million at any time prior to April 2, 2025. As of January 31, 2022, there were no outstanding borrowings under the revolving credit facility. Following this offering, we intend to replace this revolving credit facility with a new $1.0 billion revolving credit facility that will mature in 2027, and have executed a commitment letter with Bank of America, National Association, an affiliate of BofA Securities, Inc., one of the underwriters of this offering, for this new facility. The other lenders for this new facility may include affiliates of certain underwriters of this offering.

DESCRIPTION OF NOTES

The summary herein of certain provisions of the indenture referred to below does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the notes and the indenture. The following description of the particular terms of the notes supplements, and to the extent inconsistent therewith, replaces the description of the general terms and provisions of the debt securities set forth under “Description of Securities” beginning on page 2 of the accompanying prospectus. In this section, references to “Workday,” “us,” “we,” or “our” refer only to Workday, Inc. and not to any of its subsidiaries.

General

The    % notes due 20   (the “20   notes”), the    % notes due 20   (the “20   notes”) and the    % notes due 20   (the “20   notes” and, collectively with the 20   notes and the 20   notes, the “notes”) will each constitute a separate series of securities and will be issued only in book-entry form, in minimum denominations of $2,000 and multiples of $1,000 in excess thereof thereafter.

The notes will be issued under an indenture and an officer’s certificate setting forth the specific terms of the notes to be entered into concurrently with the initial issuance of the notes, by and between Workday and U.S. Bank Trust Company, National Association, as trustee, as may be supplemented from time to time. U.S. Bank Trust Company, National Association will initially be the trustee for any and all securities issued under the indenture, as amended, including the notes, and is referred to herein as the “trustee.” Workday will be the sole obligor on the notes.

Ranking

The indenture will not limit the ability of Workday to incur additional unsecured indebtedness. The notes will be the unsecured and unsubordinated obligations of Workday and will rank pari passu with its other unsecured and unsubordinated indebtedness. The notes will be structurally subordinated to all indebtedness and liabilities (including trade payables and preferred stock obligations) of Workday’s subsidiaries and will be effectively subordinated to its secured indebtedness, if any, and that of its subsidiaries, if any.

As of January 31, 2022, Workday had approximately $1.8 billion of outstanding indebtedness for borrowed money and approximately $6.0 billion of total liabilities on a consolidated basis, none of which was secured indebtedness. Of this amount, Workday’s subsidiaries had approximately $1.2 billion of liabilities (including trade payables and deferred revenue but excluding intercompany liabilities and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with generally accepted accounting principles) to which the notes would have been structurally subordinated.

Interest and Maturity

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

The 20   notes will bear interest at a rate of    % per annum, the 20   notes will bear interest at a rate of    % per annum and the 20   notes will bear interest at a rate of    % per annum Interest on the notes will be payable semi-annually in arrears on        and       , commencing on       , 2022 to the persons in whose names the notes are registered at the close of business on the preceding      or       , as the case may be, whether or not a business day. Interest on the notes will be paid to, but excluding, the relevant interest payment date. Interest on the notes will be calculated on the basis of a 360-day year comprised of twelve 30-day months. If any interest payment date or the maturity date falls on a day that is not a business day the required payment will be made on the next succeeding business day and no interest on such payment will accrue in respect of the delay.

Issuance of Additional Notes

Workday may, without the consent of the holders, increase the principal amount of each series of notes by issuing additional notes in the future on the same terms and conditions as the outstanding notes of such series, except for any differences in the issue date, the issue price, the payment of interest accrued prior to

S-19

the issue date of the additional notes and the first payment of interest following the issue date of such additional notes; provided that if the additional notes are not fungible with the applicable series of notes offered hereby for U.S. federal income tax purposes, such additional notes will have one or more separate CUSIP numbers. Under the indenture, the notes and any additional notes that Workday may issue will be treated as a single series with the outstanding notes of such series for all purposes under the indenture (except as set forth in the immediately preceding sentence), including for purposes of determining whether the required percentage of the holders of record has given approval or consent to an amendment or waiver or joined in directing the trustee to take certain actions on behalf of all holders.

Workday also may, without the consent of the holders, issue other series of debt securities under the indenture in the future on terms and conditions different from the series of notes offered hereby.

Optional Redemption

Prior to their respective Par Call Dates (as defined below), Workday may redeem the notes of such series at its option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1)

(a) the sum of the present values of the remaining scheduled payments of principal and interest on such notes to be redeemed discounted to the redemption date (assuming that such 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   basis points with respect to the 20   notes,           basis points with respect to the 20   notes and           basis points with respect to the 20   notes, in each case, less (b) interest accrued to the date of redemption; and

(2)

100% of the principal amount of such notes to be redeemed,

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

On or after the applicable Par Call Date, Workday may redeem the applicable series of notes at its 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 excluding, the redemption date.

“Par Call Date” means, with respect to the 20   notes,      , 20   (   month(s) prior to the maturity date of such notes), with respect to the 20   notes,      , 20   (      month(s) prior to the maturity date of such notes) and, with respect to the 20   notes,      , 20   (      month(s) prior to the maturity date of such notes).

“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 the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) — H.15” ​(or any successor designation or publication) (“H.15”) under the caption “U.S. government securities — Treasury constant maturities — Nominal” ​(or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the applicable Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields — one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life — and shall interpolate to the 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,

S-20

the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 or any successor designation or publication is no longer published, the Company 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, the Company shall select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

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

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.

In the case of a partial redemption, selection of the notes for redemption will be made pro rata, by lot or by such other method as the trustee in its sole discretion deems appropriate and fair in accordance with the depositary’s procedures and any applicable stock exchange’s procedures. No such note of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. Except in the case of global notes, a new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. In the case of global notes, so long as the notes are held by The Depository Trust Company (“DTC”), Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”), and Clearstream Banking, société anonyme (“Clearstream”) (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the applicable depositary.

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

Purchase 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 such notes as described above, we will be required to make an offer to each holder of such notes to purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that holder’s applicable notes at a purchase price in cash equal to 101% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that after giving effect to the purchase, any notes that remain outstanding shall have a minimum denomination of $2,000 and integral multiples of $1,000 above that amount.

Within 30 days following the date upon which the Change of Control Triggering Event has occurred or, at our option, prior to any Change of Control (as defined below), but after the public announcement of

S-21

the transaction that constitutes or may constitute the Change of Control, except to the extent that we have exercised our right to redeem the applicable notes as described under “— Optional Redemption,” we will mail or send a notice in accordance with the applicable procedures of the depositary (a “Change of Control Offer”) to each holder of notes subject to such offer with a copy to the trustee describing the transaction or transactions that constitute or may constitute a Change of Control Triggering Event and offering to purchase such notes on the date specified in the notice, which date will be no earlier than 30 days nor later than 60 days from the date such notice is mailed or sent (other than as may be required by law) (such date, the “Change of Control Payment Date”). The notice will, if mailed or sent prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date specified in the notice. The Change of Control Payment Date must be a business day.

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

•

accept for payment all notes or portions of the notes properly tendered pursuant to the Change of Control Offer;

•

deposit with the paying agent prior to 10:00 a.m. New York City time an amount equal to the change of control payment in respect of all notes or portions of notes properly tendered pursuant to the Change of Control Offer; and

•

deliver or cause to be delivered to the trustee the notes properly accepted together with an officer’s certificate stating the aggregate principal amount of notes or portions of notes being purchased.

The trustee will promptly mail, or cause the paying agent to promptly deliver, to each holder of notes so tendered the payment for such notes, and the trustee will promptly authenticate and deliver (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered, if any.

Except as described above with respect to a Change of Control Triggering Event, the indenture will not contain provisions that permit the holders to require us to purchase or redeem the notes in the event of a takeover, recapitalization or similar transaction.

We will comply, to the extent applicable, with the requirements of Rule 14(e)-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws or regulations in connection with the purchase of notes pursuant to a Change of Control Triggering Event. To the extent that the provisions of any securities laws or regulations conflict with the terms described in the notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations by virtue thereof; rather, we will be deemed to comply with our obligation to repurchase notes upon a Change of Control Triggering Event in accordance with the indenture, modified as necessary by us in good faith to permit compliance with such law or regulation.

Holders of notes electing to have notes purchased pursuant to a Change of Control Offer will be required to surrender their notes, with the form entitled “Purchase Exercise Notice Upon a Change of Control Triggering Event” on the reverse of the note completed, to the paying agent at the address specified in the notice, or transfer their notes to the paying agent by book-entry transfer pursuant to the applicable procedures of The Depository Trust Company, prior to the close of business on the third business day prior to the Change of Control Payment Date.

We will not be required to make a Change of Control Offer 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 hereunder and such third-party purchases all notes properly tendered and not withdrawn under its offer in accordance with such requirements.

In addition, we will not purchase any notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the indenture, other than a default in the payment of the change of control payment upon a Change of Control Triggering Event.

If holders of not less than 95% in aggregate principal amount of outstanding notes of such series validly tender and do not withdraw such notes in a Change of Control Offer and we, or any third party

S-22

making a Change of Control Offer in lieu of us, as described above, purchases all of the notes of such series validly tendered and not withdrawn by such holders, we will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all notes of such series that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption (subject to the right of holders of record on a record date to receive interest on the relevant interest payment date).

The definition of Change of Control includes a phrase relating to the sale, lease, transfer, conveyance or other disposition of “all or substantially all” of our assets and the assets of our subsidiaries taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise established definition of the phrase under applicable law. Accordingly, the ability of a holder of notes to require us to purchase its notes as a result of a sale, lease, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries taken as a whole to another person may be uncertain.

For purposes of the Change of Control Offer provisions of the notes, the following definitions are 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 or consolidation), in one or a series of related transactions, of all or substantially all of our assets and the assets of our subsidiaries taken as a whole to any “person” ​(as that term is used in Section 13(d)(3) of the Exchange Act) other than to us or one of our subsidiaries;

(2)

the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any “person” ​(as that term is used in Section 13(d)(3) of the Exchange Act) other than us or our subsidiaries, becomes the “beneficial owner” ​(as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of our outstanding Voting Stock, measured by voting power rather than number of shares; provided, however, that a person shall not be deemed the beneficial owner of, or to own beneficially, any securities tendered pursuant to a tender or exchange offer made by or on behalf of such person or any of such person’s affiliates (as defined in the indenture) until such tendered securities are accepted for purchase or exchange thereunder;

(3)

we consolidate with, or merge with or into, any person, or any person consolidates with, or merges with or into, us, in any such event pursuant to a transaction in which any of our outstanding Voting Stock or the outstanding Voting Stock 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, or any direct or indirect parent of the surviving person, immediately after giving effect to such transaction; or

(4)

the adoption of a plan by our board of directors relating to our liquidation or dissolution.

Notwithstanding the foregoing, a transaction will not be considered to be a Change of Control if (1) we become a direct or indirect wholly owned subsidiary of a holding company and (2) immediately following that transaction, (a) the direct or indirect holders of the Voting Stock of the holding company are substantially the same as the holders of our Voting Stock in substantially the same proportions immediately prior to that transaction or (b) no person or group is the beneficial owner, directly or indirectly, of more than a majority of the total voting power of the Voting Stock of the holding company.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Ratings Event.

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

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category of Moody’s); a rating of BBB- or better by S&P (or its equivalent under any

S-23

successor rating category of S&P); and a rating of BBB- or better by Fitch (or its equivalent under any successor rating category of Fitch) and the equivalent investment grade rating from any replacement Rating Agency or Agencies appointed by us.

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

“Rating Agency” means each of Moody’s and S&P; provided, that if, after the date of the initial issuance of the notes, Fitch rates the notes of a series and makes such rating publicly available, Rating Agency shall mean each of Moody’s, S&P and Fitch; provided, that if any of Moody’s or S&P ceases to rate the notes of a series or fails to continue to make a rating of such notes publicly available, we will appoint a replacement for such Rating Agency that is a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act.

“Ratings Event” means, with respect to a series of notes, that such notes are rated below Investment Grade by at least two of the three Rating Agencies (if the notes at such time are rated by three Rating Agencies) or by both Rating Agencies (if the notes at such time are rated by two Rating Agencies), on any day during the period (the “Trigger Period”) commencing on the date 60 days prior to the first public announcement by us of any Change of Control (or pending Change of Control) and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended for so long as the rating of such notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies); provided, however, that a Ratings Event otherwise arising by virtue of a particular reduction in rating will not be deemed to have occurred in respect of a particular Change of Control (and thus will not be deemed a Ratings Event for purposes of the definition of Change of Control Repurchase Event) unless each of the Rating Agencies announces or publicly confirms or informs the trustee in writing at Workday’s or its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control has occurred at the time of the ratings event).

“S&P” means S&P 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.

we would be entitled to incur Indebtedness secured by a mortgage on the Principal Property to be leased in an amount equal to the Attributable Liens with respect to such sale and lease-back transaction without equally and ratably securing the notes pursuant to the first paragraph of “— Limitation on Liens” above; or

(5)

we apply an amount equal to the fair value of the Principal Property sold to the purchase of Property or to the retirement of our long-term Indebtedness that is pari passu with the notes (including the notes) within 365 days of the effective date of any such sale and lease-back transaction. In lieu of applying such amount to such retirement, we may deliver debt securities that rank pari passu with notes (including the notes) to the trustee under the indenture therefor for cancellation, such debt securities to be credited at the cost thereof to us.

Notwithstanding the foregoing, we and/or our Restricted Subsidiaries may enter into any sale and lease-back transaction which would otherwise be subject to the foregoing restrictions if after giving effect thereto and at the time of determination, Aggregate Debt does not exceed the greater of (a) 15% of our Consolidated Net Tangible Assets calculated as of the date of creation or incurrence of the Lien and (b) $1.0 billion.

S-25

No Sinking Fund

The notes will not be entitled to any sinking fund.

Book-Entry; Delivery and Form; Global Note

The notes of each series will be issued in the form of one or more fully registered global notes without interest coupons which will be deposited with, or on behalf of, DTC, New York, New York, and registered in the name of Cede & Co., as nominee of DTC, for the accounts of participants in DTC. Unless and until exchanged, in whole or in part, for notes in definitive registered form, a global note may not be transferred except as a whole (i) by the depositary for such global note to a nominee of such depositary, (ii) by a nominee of such depositary to such depositary or another nominee of such depositary or (iii) by such depositary or any such nominee to a successor of such depositary or a nominee of such successor.

Ownership of beneficial interests in a registered global note will be limited to persons, called participants, that have accounts with the depositary (currently DTC) or persons that may hold interests through participants in DTC. Investors may hold their interests in a global note directly through Euroclear and Clearstream, if they are participants in such systems, or indirectly through organizations that are participants in such systems. Euroclear and Clearstream will hold interests in a global note on behalf of their participants through their respective depositaries, which in turn will hold such interests in the global note in customers’ securities accounts in the depositaries’ names on the books of DTC.

S-29

Upon transfer of a definitive note, the definitive note will be exchanged for an interest in a global note, and the transferee will be required to hold its interest through a participant in DTC, Euroclear or Clearstream, as applicable.

Upon the issuance of a registered global note, the depositary will credit, on its book-entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the notes beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the notes will designate the accounts to be credited. Ownership of beneficial interests in a registered global note will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants.

So long as the depositary, or its nominee, is the registered owner of a registered global note, that depositary or its nominee, as the case may be, will be considered the sole owner or holder of the notes represented by the registered global note for all purposes under the indenture. Except as described below, owners of beneficial interests in a registered global note will not be entitled to have the notes represented by the registered global note registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered the owners or holders of the notes under the indenture. Accordingly, each person owning a beneficial interest in a registered global note must rely on the procedures of the depositary for that registered global note and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the indenture. The laws of some states may require that some purchasers of notes take physical delivery of these notes in definitive form. Such laws may impair the ability to transfer beneficial interests in a global note.

To facilitate subsequent transfers, all notes deposited by participants with DTC will be registered in the name of DTC’s nominee, Cede & Co. The deposit of the notes with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC will have no knowledge of the actual beneficial owners of the notes. DTC’s records reflect only the identity of the direct participants to whose accounts such notes are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.

Workday will make payments due on the notes to Cede & Co., as nominee of DTC, in immediately available funds. DTC’s practice upon receipt of any payment of principal, premium, interest or other distribution of underlying securities or other property to holders on that registered global note, is to immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global note as shown on the records of the depositary. Payments by participants to owners of beneficial interests in a registered global note held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of those participants. Payment to Cede & Co. is the responsibility of Workday. Disbursement of such payments to direct participants is the responsibility of Cede & Co. Disbursement of such payments to the beneficial owners is the responsibility of direct and indirect participants. None of Workday, the underwriters of this offering, the trustee or any other agent of ours or any agent of the trustee will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global note or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

Transfers between participants in Euroclear and Clearstream will be effected in the ordinary way in accordance with their respective rules and operating procedures. If a holder requires physical delivery of a definitive note for any reason, including to sell notes to persons in jurisdictions that require such delivery of such notes or to pledge such notes, such holder must transfer its interest in the relevant global note in accordance with the normal procedures of DTC and the procedures set forth in the indenture.

Cross-market transfers between DTC, on the one hand, and directly or indirectly through Euroclear or Clearstream participants, on the other, will be effected by DTC in accordance with DTC 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

S-30

counterparty in such system in accordance with its rules and procedures and within its established deadlines (Brussels time). 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 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.

Because of the time zone differences, the securities account of a Euroclear or Clearstream participant purchasing an interest in the global note from a DTC participant will be credited during the securities settlement processing day (which must be a business day for Euroclear or Clearstream, as the case may be) immediately following the DTC settlement date, and such credit of any transaction’s interests in the global note settled during such processing day will be reported to the relevant Euroclear or Clearstream participant on such day. Cash received in Euroclear or Clearstream as a result of sales of interests in a global note by or through a Euroclear or Clearstream participant to a DTC participant will be received with value on the DTC settlement date, but will be available in the relevant Euroclear or Clearstream cash account only as of the business day following settlement in DTC.

Workday expects that DTC will take any action permitted to be taken by a holder of notes only at the direction of one or more participants to whose account the DTC interests in a global note are credited and only in respect of such portion of the aggregate principal amount of the notes as to which such participant or participants has or have given such direction. However, if there is an event of default under the notes, DTC will exchange each global note for definitive notes, which it will distribute to its participants.

Although Workday expects that DTC, Euroclear and Clearstream will agree to the foregoing procedures in order to facilitate transfers of interests in each global note among participants of DTC, Euroclear and Clearstream, DTC, Euroclear and Clearstream are under no obligation to perform or continue to perform such procedures, and such procedures may be discontinued at any time. None of Workday, the underwriters of this offering, the trustee or any other agent of ours or any agent of the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream or their participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

If the depositary for any of the notes represented by a registered global note is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Exchange Act, and a successor depositary registered as a clearing agency under the Exchange Act is not appointed by Workday within 90 days, Workday will issue notes in definitive form in exchange for the registered global note that had been held by the depositary. Any notes issued in definitive form in exchange for a registered global note will be registered in the name or names that the depositary gives to the trustee or other relevant agent. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global note that had been held by the depositary. In addition, Workday may at any time determine that the notes shall no longer be represented by a global note and will issue notes in definitive form in exchange for such global note pursuant to the procedure described above. In connection with any proposed exchange involving a note in definitive form, or any exchange of a note in definitive form for a global note or vice versa, there shall 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.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC was created to hold securities of its participants and to facilitate the clearance and settlement of securities transactions, such as transfers and pledges, among its participants in such securities through electronic computerized book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom own DTC. Access to DTC’s book-entry system

S-31

is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the SEC.

Euroclear and Clearstream hold securities for participating organizations. They also facilitate the clearance and settlement of securities transactions between their respective participants through electronic bookentry changes in the accounts of such participants. Euroclear and Clearstream provide various services to their participants, including the safekeeping, administration, clearance, settlement, lending and borrowing of internationally traded securities. Euroclear and Clearstream interface with domestic securities markets. Euroclear and Clearstream participants are financial institutions such as underwriters, securities brokers and dealers, banks, trust companies and certain other organizations.

Indirect access to Euroclear or Clearstream is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Euroclear or Clearstream participant, either directly or indirectly.

The information in this section concerning DTC and DTC’s book-entry system, as well as information regarding Euroclear and Clearstream, has been obtained from sources that Workday believes to be reliable, but Workday takes no responsibility for its accuracy or completeness. Workday assumes no responsibility for the performance by DTC, Euroclear, Clearstream or their respective participants of their respective obligations, including obligations that they have under the rules and procedures that govern their operations.

Notices

Notices to holders of certificated notes will be made by first class mail, postage prepaid, to the addresses that appear on the security register of the notes. Any notices required to be given to the holders while the notes are global notes will be given only to DTC and shall be sufficiently given if given to DTC (or its designee) pursuant to the standing instructions from DTC or its designee, including by electronic mail in accordance with its applicable procedures.

Concerning Our Relationship with the Trustee

The trustee assumes no responsibility for the accuracy or completeness of the information concerning us or our affiliates or any other party contained in this document or the related documents or for any failure by us or any other party to disclose events that may have occurred and may affect the significance or accuracy of such information. The trustee shall not be responsible for determining whether any Change of Control has occurred and whether any Change of Control Offer with respect to the notes is required. The trustee shall not be responsible for monitoring our rating status, making any request upon any Rating Agency, or determining whether any Ratings Event with respect to the notes has occurred.

S-32

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of material U.S. federal income tax considerations generally applicable to the purchase, ownership, and disposition of the notes. This summary is based on the Internal Revenue Code of 1986, as amended (the “Code”), U.S. Treasury regulations, judicial decisions and administrative rulings, and other applicable authorities, all as in effect as of the date hereof and all of which are subject to change or differing interpretations, possibly with retroactive effect. This summary does not address all aspects of U.S. federal income taxes and does not deal with all tax consequences that may be relevant to holders in light of their personal circumstances or particular situations, such as:

•

dealers in securities, banks, financial institutions, regulated investment companies, real estate investment trusts, cooperatives, tax-exempt entities, insurance companies, taxpayers subject to special tax accounting rules, or traders in securities that elect to use a mark-to-market method of accounting for their securities;

•

persons holding notes as a part of an integrated or conversion transaction or a straddle;

•

persons deemed to sell the notes under the constructive sale provisions of the Code;

•

tax consequences to U.S. holders (as defined below) whose “functional currency” is not the U.S. dollar;

•

“controlled foreign corporations,” “passive foreign investment companies,” corporations that accumulate earnings to avoid federal income tax or certain former citizens or long-term residents of the United States; or

•

taxpayers that are, or hold their notes through, partnerships or other pass-through entities.

In addition, this discussion does not address the considerations of the alternative minimum tax, the Medicare contribution tax on net investment income, the requirement under Section 451(b) of the Code for certain taxpayers to conform the timing of income accruals for U.S. federal income tax purposes to their financial statements, gift or estate tax or any state, local or non-U.S. tax considerations or any tax considerations other than U.S. federal income tax considerations. This summary deals only with persons who hold the notes as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment) by a beneficial owner who purchased the notes on original issuance at their”issue price” within the meaning of Section 1273 of the Code (i.e., the first price at which a substantial portion of the notes is sold to persons other than bond houses, brokers, or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers). No assurance can be given that the U.S. Internal Revenue Service (“IRS”) would not assert, or that a court would not sustain, a position contrary to any of those set forth below. We have not sought and will not seek any ruling from the IRS with respect to the statements made and the conclusions reached in the following summary. Holders are urged to consult their tax advisors as to the particular U.S. federal tax considerations applicable to them of the purchase, ownership, and disposition of notes, as well as the effects of state, local and non-U.S. tax laws.

For purposes of this summary, a “non-U.S. holder” means any beneficial owner of a note (other than a partnership or other pass-through entity for U.S. federal income tax purposes) that is not a “U.S. holder.” A “U.S. holder” means a beneficial owner of a note (as determined for U.S. federal income tax purposes) that, for U.S. federal income tax purposes, is, or is treated as, (i) a citizen or individual resident of the U.S., (ii) a corporation created or organized in the United States or under the laws of the United States or any state thereof, or the District of Columbia, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) a trust if (A) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (B) the trust has a valid election in effect under applicable Treasury regulations to be treated as a U.S. person.

If a partnership (including any entity or arrangement treated as a partnership or other pass-through entity for U.S. federal income tax purposes) is a beneficial owner of a note, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of such partnership. Partners and partnerships should consult their tax advisors as to the particular U.S. federal income tax considerations applicable to them.

S-33

Upon the occurrence of a “Change of Control Triggering Event,” as described above under “Description of notes — Purchase Upon Change of Control Triggering Event,” we may be obligated to offer to purchase the notes of any series for a purchase price equal to 101% of the principal amount of the notes of such series, plus accrued and unpaid interest (if any). We intend to take the position that, under the applicable Treasury regulations, the notes of each series should not be treated as contingent payment debt instruments due to this obligation. Under the applicable Treasury regulations, a contingency will not cause a debt instrument to be treated as a contingent payment debt instrument if such contingency is remote or incidental. We believe that the likelihood that the notes of any series will be repurchased upon a Change of Control Triggering Event is remote. Our position is binding on you unless you disclose your contrary position in the manner required by the applicable Treasury regulations. The IRS, however, may take a position contrary to our position, which could affect the timing and character of your taxable income with respect to the notes for U.S. federal income tax purposes. You are urged to consult your tax advisors regarding the potential application to the notes of the contingent payment debt instrument rules. This discussion assumes that the notes will not be considered contingent payment debt instruments for U.S. federal income tax purposes.

Investors considering the purchase of notes are urged to consult their tax advisors with respect to the application of the U.S. federal income tax laws to their particular situations as well as any tax consequences arising under the U.S. federal estate or gift tax rules or under the laws of any state, local or foreign jurisdictions or under any applicable tax treaty.

U.S. holders

Payments of interest

We expect, and this summary assumes, that the notes will be issued with less than de minimis original issue discount, if any (as determined under the Code). In such case, interest on a note will generally be treated as ordinary income at the time it is paid or accrued in accordance with the U.S. holder’s regular method of accounting for U.S. federal income tax purposes.

Sale, exchange, redemption, retirement or other taxable disposition of the notes

A U.S. holder will generally recognize gain or loss upon a sale, exchange, redemption, retirement or other taxable disposition of a note, equal to the difference, if any, between (i) the sum of the cash plus the fair market value of any other property received upon such disposition (excluding any amount attributable to accrued but unpaid interest, which will be treated as described above under “ — Payments of interest”) and (ii) such U.S. holder’s adjusted tax basis in the note. A U.S. holder’s adjusted tax basis in a note will generally be equal to the amount that the U.S. holder paid for the note. If, at the time of the sale, exchange, redemption, retirement or other taxable disposition of the note, a U.S. holder held the note for more than one year, such gain or loss will be long-term capital gain or loss. Long-term capital gains recognized by certain non-corporate U.S. holders, including individuals, will generally be subject to a reduced rate of U.S. federal income tax. A U.S. holder’s ability to deduct capital losses may be limited.

Backup withholding and information reporting

In general, a U.S. holder will be subject to U.S. federal backup withholding at the applicable rate (currently 24%) with respect to payments of interest on the notes and the proceeds of a sale, exchange, redemption, retirement or other taxable disposition of the notes, unless the U.S. holder (i) is an “exempt recipient” ​(such as a corporation or tax-exempt organization) and, when required, provides appropriate documentation to that effect, or (ii) provides its taxpayer identification number to the applicable withholding agent and certifies, under penalty of perjury, that it is not subject to backup withholding on an IRS Form W-9 (Request for Taxpayer Identification Number and Certification) or an applicable successor form and otherwise complies with the applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. holder may be allowed as a credit against such U.S. holder’s U.S. federal income tax liability, if any, and may entitle such U.S. holder to a refund, provided the required information is furnished to the IRS in a timely manner. In addition, payments on the notes made to, and the proceeds of a sale, exchange, redemption, retirement or

S-34

other taxable disposition by, a U.S. holder will generally be subject to information reporting, unless such U.S. holder is an exempt recipient and appropriately establishes that exemption.

Non-U.S. holders

Payments of interest

Subject to the discussions below under “— Information reporting and backup withholding” and “—​Foreign Account Tax Compliance Act,” payments of interest on the notes made to a non-U.S. holder will generally not be subject to U.S. federal withholding tax, provided that:

•

the non-U.S. holder does not actually or constructively own 10% or more of the total combined voting power of all classes of stock of the Company entitled to vote within the meaning of the Code;

•

the non-U.S. holder is not a controlled foreign corporation that is related to the Company (actively or constructively) within the meaning of the Code;

•

the non-U.S. holder is not a bank whose receipt of interest on the Notes is described in Section 881(c)(3)(A) of the Code; and

•

the non-U.S. holder provides its name and address on an IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable form) and certifies, under penalties of perjury, that it is not a U.S. person, or (ii) the non-U.S. holder holds the notes through certain foreign intermediaries or certain foreign partnerships, and the non-U.S. holder and the foreign intermediaries or foreign partnerships satisfy the certification requirements of applicable Treasury regulations.

A non-U.S. holder that does not meet the above criteria will be subject to U.S. federal withholding tax at a flat rate of 30%, unless the withholding tax rate is reduced or eliminated by an applicable income tax treaty, and such non-U.S. holder is a qualified resident of the treaty country and such non-U.S. holder provides the paying agent with a properly completed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable form). A non-U.S. holder will also be exempt from withholding tax if the interest received is effectively connected with the conduct of a U.S. trade or business (and if a tax treaty applies, is attributable to a permanent establishment within the United States) and such non-U.S. holder provides the paying agent with a properly completed IRS Form W-8ECI.

If interest on the notes is effectively connected with the conduct of a United States trade or business of the non-U.S. holder (and if required by an applicable income tax treaty, such interest is attributable to a permanent establishment within the United States), the non-U.S. holder will generally be subject to U.S. federal income tax on the receipt or accrual of such interest on a net income basis in the same manner as if the non-U.S. holder were a U.S. holder. In addition, if such non-U.S. holder is a foreign corporation, it may be subject to an additional branch profits tax equal to 30% (or lower applicable treaty rate) of its effectively connected earnings and profits for the taxable year, subject to adjustments. Non-U.S. holders whose interest income is effectively connected with the conduct of a United States trade or business are urged to consult their tax advisors concerning the U.S. federal income tax consequences to them of the purchase, ownership, and disposition of the notes as well as the application of state, local and non-U.S. income and other tax laws.

Sale, exchange, redemption, retirement or other taxable disposition of the notes

Subject to the discussions below under “— Information reporting and backup withholding” and “— Foreign Account Tax Compliance Act,” a non-U.S. holder will generally not be subject to U.S. federal income taxation with respect to gain realized on the sale, exchange, redemption, retirement or other disposition of a note, unless:

(1)

the gain is effectively connected with the conduct of a United States trade or business (and, in the case of certain tax treaties, the gain is attributable to a permanent establishment within the United States), in which case such gain will be taxed on a net income basis in the same manner as interest that is effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States as described above; or

S-35

(2)

in the case of an individual, such individual is present in the United States for 183 days or more during the taxable year in which such gain is realized and certain other conditions are met, in which case the non-U.S. holder will be subject to a tax, currently at a rate of 30% (or, if applicable, a lower treaty rate), on the excess, if any, of such gain plus all other U.S. source capital gains recognized by such holder during the same taxable year over the non-U.S. holder’s U.S.-source capital losses recognized during such taxable year.

Information reporting and backup withholding

The amount of interest paid to a non-U.S. holder, and the amount of any tax withheld with respect to such interest, must be reported annually to the IRS and the non-U.S. holder. Copies of the information returns reporting the amount of such interest and the amount of any tax withheld may also be made available to the tax authorities in the country in which the non-U.S. holder resides under the provisions of an applicable tax treaty.

In general, a non-U.S. holder will not be subject to backup withholding with respect to payments of interest on a note provided that the payor does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. person and the certification requirements described in the last bullet point under “— Payments of interest” have been met.

In addition, a non-U.S. holder will generally be subject to information reporting and possibly backup withholding with respect to the proceeds of the sale or other disposition (including a redemption or retirement) of a note within the U.S. or conducted through certain U.S.-related financial intermediaries, unless (i) the certification requirements above have been met and the payor does not have actual knowledge or reason to know that the non-U.S. holder is a U.S. person, as defined under the Code, or (ii) the non-U.S. holder otherwise establishes an exemption.

Backup withholding is not an additional tax. A non-U.S. holder generally will be entitled to credit any amounts withheld under the backup withholding rules against its U.S. federal income tax liability provided that the required information is furnished to the IRS in a timely manner.

Foreign Account Tax Compliance Act

Under Sections 1471 through 1474 of the Code and the Treasury regulations promulgated thereunder, or FATCA, a 30% U.S. federal withholding tax may apply to certain “withholdable payments,” in each case paid to (i) a “foreign financial institution” ​(as specifically defined in the Code) (whether such foreign financial institution is a beneficial owner or an intermediary) that does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) its compliance (or deemed compliance) with FATCA (which may alternatively be in the form of compliance with an intergovernmental agreement with the United States) in a manner that avoids withholding, or (ii) a “non-financial foreign entity” ​(as specifically defined in the Code) (whether such non-financial foreign entity is a beneficial owner or an intermediary) which does not provide sufficient documentation, typically on IRS Form W-8BEN-E, evidencing either (x) an exemption from FATCA, or (y) adequate information regarding certain substantial United States beneficial owners of such entity (if any). Non-U.S. entities located in jurisdictions that have entered into an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

FATCA withholding generally will apply to interest paid on our notes. The Treasury Secretary has issued proposed regulations providing that the withholding provisions under FATCA do not apply with respect to payment of gross proceeds from a sale or other disposition of our notes, which proposed regulations may be relied upon by taxpayers until final regulations are issued. Prospective investors should consult their tax advisors regarding the possible implications of FATCA on their investment in the notes.

UNDERWRITING (CONFLICTS OF INTEREST)

BofA Securities, Inc., Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC are acting as representatives of the underwriters named below. Subject to the terms and conditions stated in the underwriting agreement dated the date of this prospectus supplement, each underwriter named below will severally agree to purchase, and we will agree to sell to that underwriter, the principal amount of the notes set forth opposite the underwriter’s name.

Underwriter	Principal amount of notes to be Purchased
BofA Securities, Inc.	​	$
Morgan Stanley & Co. LLC	​	​	​
Wells Fargo Securities, LLC	​	​	​
Total	​	$	​

The underwriting agreement will provide that the obligations of the underwriters to purchase the notes included in this offering are subject to approval of legal matters by counsel and to other conditions. Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed, severally and not jointly, to purchase all the notes if they purchase any of the notes. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part. If an underwriter defaults, the underwriting agreement provides that the purchase commitments of the nondefaulting underwriters may be increased or the underwriting agreement may be terminated.

The underwriters propose to offer the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and some of the notes to dealers at the public offering price less a concession not to exceed     % of the principal amount of the notes. The underwriters may allow, and any such dealer may reallow, a concession not to exceed     % of the principal amount of the notes. After the initial offering of the notes to the public, the representatives may change the public offering price and other selling terms.

The following table shows the underwriting discount that we will pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the notes):

​	Paid By Us
Per note	​	​	%
% Notes due 20	​	​	​
% Notes due 20	​	​	​
% Notes due 20	​	​	​
Total	​	$

We estimate that our total expenses for this offering will be approximately $     million, excluding underwriting discount.

We will agree with the underwriters, subject to certain exceptions, not to, except with the prior written consent of BofA Securities, Inc., Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by us during the period from the date of this prospectus supplement continuing through the day following the settlement date of the notes.

In connection with the offering, the underwriters may purchase and sell the notes in the open market. Purchases and sales in the open market may include short sales, purchases to cover short positions and stabilizing purchases.

•

Short sales involve secondary market sales by the underwriters of a greater number of the notes than they are required to purchase in this offering.

S-37

•

Covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions.

•

Stabilizing transactions involve bids to purchase the notes so long as the stabilizing bids do not exceed a specified maximum. Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the notes.

Purchases to cover short positions and stabilizing purchases, as well as other purchases by the underwriters for their own accounts, may have the effect of preventing or retarding a decline in the market price of the notes. They may also cause the price of the notes to be higher than the price that would otherwise exist in the open market in the absence of these transactions. The underwriters may conduct these transactions in the over-the-counter market or otherwise. If the underwriters commence any of these transactions, they may discontinue them at any time.

Conflicts of Interest

We plan to use a portion of the net proceeds from this offering to repay outstanding borrowings under our Term Loan. Bank of America, N.A., Morgan Stanley Bank, N.A. and Wells Fargo Bank, National Association are each lenders under our Term Loan and are each affiliates of BofA Securities, Inc., Morgan Stanley & Co. LLC and Wells Fargo Securities, LLC, respectively. In addition, certain of the underwriters or their affiliates may own our 0.25% Convertible Senior Notes due 2022 that we may purchase, redeem or repay with a portion of the net proceeds of this offering. In the event that any of these underwriters, together with their respective affiliates, receives at least 5% of the net proceeds of this offering, such underwriters will be deemed to have a “conflict of interest” within the meaning of FINRA Rule 5121. However, in accordance with FINRA Rule 5121, no “qualified independent underwriter” is required because the notes are investment grade-rated by one or more nationally recognized statistical rating agencies.

Other Relationships

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. The underwriters and their respective affiliates have in the past performed commercial banking, investment banking and advisory services for us from time to time for which they have received customary fees and reimbursement of expenses and may, from time to time, engage in transactions with and perform services for us in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses. For example, Bank of America, N.A., an affiliate of BofA Securities, Inc., Morgan Stanley Bank, N.A., an affiliate of Morgan Stanley & Co. LLC, and Wells Fargo Bank, National Association, an affiliate of Wells Fargo Securities, LLC, are lenders under our credit facility. Additionally, we have executed a commitment letter with Bank of America, National Association, an affiliate of BofA Securities, Inc., one of the underwriters of this offering, to replace our existing revolving credit facility with a new $1.0 billion revolving credit facility that will mature in 2027. The other lenders for this new facility may include affiliates of certain underwriters of this offering.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative instruments) and financial instruments (which may include bank loans and/or credit default swaps) for their own account and for the accounts of their customers. Such investment and securities activities may involve our securities and instruments. If any of the underwriters or their affiliates has a lending relationship with us, certain of those underwriters or their affiliates 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

S-38

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.

We will agree to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriters may be required to make because of any of those liabilities.

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

Securities legislation in certain provinces or territories of Canada may provide a purchaser with remedies for rescission or damages if this prospectus supplement and the accompanying prospectus (including any amendment thereto) contain a misrepresentation, provided that the remedies for rescission or damages are exercised by the purchaser within the time limit prescribed by the securities legislation of the purchaser’s province or territory. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser’s province or territory for particulars of these rights or consult with a legal advisor.

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

Prohibition of Sales to EEA Retail Investors

The notes are not intended to be offered, sold, or otherwise made available to and should not be offered, sold, or otherwise made available to any retail investor in the European Economic Area (the “EEA”).

Consequently no key information document required by Regulation (EU) No 1286/2014 (as amended, the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law by virtue of the EUWA (the “UK PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail

investors in the UK has been prepared, and therefore, offering or selling the notes or otherwise making them available to any retail investor in the UK may be unlawful under the UK PRIIPs Regulation.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus and any prospectus supplement, including the documents incorporated by reference herein and therein, contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained in or incorporated by reference in this prospectus and any prospectus supplement other than statements of historical fact, including statements regarding our future operating results and financial position, our business strategy and plans, and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “seek,” “plan,” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, operating results, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including those described in the “Risk Factors” section incorporated by reference herein. Moreover, we operate in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this prospectus and any prospectus supplement may not occur and actual results could differ materially and adversely from those anticipated or implied by the forward-looking statements.

You should not rely upon forward-looking statements as predictions of future events. The events and circumstances reflected in the forward-looking statements may not be achieved or occur. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee future results, levels of activities, performance, or achievements. Although we undertake no obligation to revise or update any forward-looking statements, whether as a result of new information, future events or otherwise, you are advised to review any additional disclosures we make in the documents we subsequently file with the SEC that are incorporated by reference in this prospectus and any prospectus supplement. See “Where You Can Find Additional Information.”

Additionally, we may use a portion of the net proceeds to us for acquisitions of or investments in complementary businesses, technologies, or other assets. We may also use the net proceeds to refinance or to repay outstanding indebtedness if so specified in the applicable prospectus supplement. Pending other uses, we intend to invest the net proceeds to us in investment-grade, interest-bearing securities such as money market funds, certificates of deposit, or direct or guaranteed obligations of the U.S. government, or hold as cash. We cannot predict whether the net proceeds invested will yield a favorable return. Our management will have broad discretion in the application of the net proceeds we receive from the sale of the securities offered hereby, and investors will be relying on the judgment of our management regarding the application of the net proceeds.
