The Western Union Company is offering $ aggregate principal amount of 4.750% Notes due 2029 (the “notes”). Interest on the notes will be set at a per annum rate equal to 4.750%.

The notes offered hereby constitute a further issuance of our 4.750% notes due 2029, of which $450,000,000 aggregate principal amount was issued on March 9, 2026 (the “existing notes”). The notes offered hereby will form a single series with, and have the same terms as, the existing notes (other than the initial offering price and the issue date).

Our Company

The Western Union Company is a leader in cross-border, cross-currency money movement, payments and digital financial services, empowering consumers, businesses, financial institutions and governments with fast, reliable and convenient ways to send money and make payments around the world. Our goal is to offer accessible financial services that help people and communities prosper. The Western Union brand is globally recognized and represents speed, reliability, trust and convenience. As of December 31, 2025, our global network included agent locations in more than 200 countries and territories and many Western Union branded websites. Each location in our agent network is capable of facilitating a consumer’s use of one or more of our services, with the significant majority offering a Western Union branded service.

Our business consists of the following segments:

•

Consumer Money Transfer – Our Consumer Money Transfer segment facilitates money transfers, which are primarily sent from our retail agent and Company-operated locations worldwide or through websites and mobile devices. Our money transfer service is provided through one interconnected global network. This service is available for international cross-border transfers and, in certain countries, intra-country transfers.

•

Consumer Services – Our Consumer Services segment includes our bill payment services, money order services, travel money services, check acceptance services, media network, prepaid cards, lending partnerships and digital wallets.

We believe that brand strength, reach of our global network, convenience, reliability and value have been important to our business. As we continue to seek to meet the needs of our customers for fast, reliable and convenient global money movement and payment services while focusing on regulatory compliance, we are also working to go beyond these services by providing consumers and our business clients with access to an expanding portfolio of financial services and to increase the ways our services can be accessed, including through the launch of our digital wallet in certain countries.

Our business strategy centers on leveraging our global retail network and growing digital platforms to provide cross-border money movement and related financial services to customers worldwide, while increasingly operating as a digital-first company. Building on our traditional strength in consumer remittances, we are focused on expanding higher-growth digital channels alongside our physical agent locations to create a two-sided global financial services network. In November 2025, we announced our “Beyond” strategy, in which we intend to

S-1

serve customers by broadening our consumer services offerings and modernizing our payments infrastructure. This strategy emphasizes technology-led innovation, including expansion of digital wallets, consumer financial services, and a digital asset network supported by a U.S. dollar-denominated stablecoin initiative.

Our principal executive offices are located at 7001 East Belleview Avenue, Denver, Colorado 80237, and our telephone number is (866) 405-5012.

Recent Developments

On August 10, 2025, The Western Union Company entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Western Union Company, International Money Express, Inc. (“Intermex”), and Ivey Merger Sub, Inc., a wholly owned subsidiary of The Western Union Company. Pursuant to the Merger Agreement, on the terms and subject to the conditions set forth therein, Ivey Merger Sub, Inc. will merge with and into Intermex (the “Merger”), with Intermex continuing as the surviving corporation in the Merger and becoming a wholly owned subsidiary of The Western Union Company (the “Intermex Acquisition”). Intermex is a leading omnichannel money transfer provider, focused primarily on the United States to Latin America and the Caribbean corridors, through a network of agent retail locations, Intermex-operated stores, its mobile app and websites.

The Western Union Company will purchase the entire share capital of Intermex for approximately $500 million in cash. The Intermex Acquisition is expected to close in the second quarter of 2026, subject to the satisfaction of customary closing conditions, including receipt of remaining regulatory approvals. We cannot assure you that the Intermex Acquisition will be completed on the terms or timeline anticipated, or at all. See “Risk Factors—Risks Relating to the Intermex Acquisition.”

The completion of this offering is not contingent on the consummation of the Intermex Acquisition, nor is the consummation of the Intermex Acquisition contingent on this offering. This offering is not conditioned upon, and will be consummated before the closing of the Intermex Acquisition.

Risk Factors

Investing in the notes involves risks. See “Risk Factors” beginning on page S-6 of this prospectus supplement, page 5 of the accompanying prospectus and page 17 of our Annual Report on Form 10-K for the year ended December 31, 2025 filed with the SEC for a discussion of certain of the risks you should consider before investing in the notes.

Denominations

Form

We will issue the notes in the form of one or more fully registered global notes registered in the name of the nominee of DTC.

Clearstream and Euroclear, as operator of the Euroclear System, will hold interests on behalf of their participants through their respective U.S. depositaries, which in turn will hold such interests in accounts as participants of DTC. Except in the limited circumstances described in this prospectus supplement, owners of beneficial interests in the notes will not be entitled to have notes registered in their names, will not receive or be entitled to receive notes in definitive form and will not be considered holders of notes under the indenture.

Qualified Reopening

For U.S. federal income tax purposes, we intend to treat the new notes offered hereby as being issued in a “qualified reopening” of the existing notes. Debt instruments issued in a qualified reopening are treated as part of the same issue as the original debt instruments for U.S. federal income tax purposes. Under such treatment, the notes offered hereby will have the same issue date and issue price as the existing notes. Similarly, because the existing notes were not issued with original issue discount (“OID”) for U.S. federal income tax

S-4

purposes, the new notes offered hereby should not be treated as having been issued with OID. See “Material U.S. Federal Income Tax-Considerations—Qualified Reopening and Pre-Acquisition Accrued Interest.”

Additional Notes

The indenture governing the notes does not, and the notes will not, limit the aggregate principal amount of notes or other debt securities or other debt that we or our subsidiaries may issue. We may issue from time to time other series of debt securities, but such series will be separate from the notes. In addition, we may issue additional notes of the same series as the notes without the consent of, or notice to, the holders of the outstanding notes.

Listing

The notes will not be listed on any securities exchange or included in any automated quotation system.

Trustee, Paying Agent and Registrar

U.S. Bank Trust Company, National Association.

Governing Law

RISK FACTORS

An investment in the notes is subject to various risks. These risks should be considered carefully with the information provided elsewhere and incorporated by reference in this prospectus supplement and the accompanying prospectus before deciding to invest in the notes, including the risk factors incorporated by reference herein from our Annual Report on Form 10-K for the year ended December 31, 2025, as updated by the annual, quarterly and other reports and documents that we file with the SEC after the date of this prospectus supplement and that are incorporated by reference herein or in the accompanying prospectus. In addition, please read the information included or incorporated by reference under “Forward-Looking Statements” in this prospectus supplement for a description of additional uncertainties associated with our business, results of operations and financial condition and the forward-looking statements included or incorporated by reference in this prospectus supplement and the accompanying prospectus.

Risks Relating to the Intermex Acquisition

The pending Intermex Acquisition may not be completed on the anticipated timeline or terms, and, even if completed, we may not be able to realize the anticipated benefits.

Consummation of the Intermex Acquisition is conditioned on, among other things, the receipt of certain consents and other approvals under the competition laws of various jurisdictions. Neither we nor Intermex can provide assurance that the conditions to completing the Intermex Acquisition will be satisfied or waived and, accordingly, that the Intermex Acquisition will be completed on the terms or timeline that the parties anticipate, or at all. If any condition to the Intermex Acquisition is not satisfied, it could delay or prevent the Intermex Acquisition from occurring, which could negatively impact our business, financial condition, results of operations and growth prospects.

The Intermex Acquisition involves the combination of two companies that currently operate as independent companies. While we and Intermex will continue to operate independently until the completion of the Intermex Acquisition, the success of the Intermex Acquisition will depend, in part, on our ability to realize the anticipated benefits from successfully combining our and Intermex’s businesses after closing. We plan on devoting substantial management attention and resources to integrating our and Intermex’s business practices so that we can fully realize the anticipated benefits of the Intermex Acquisition, which may divert attention from our own operations and the pursuit of other opportunities that could have been beneficial for us. The business and assets acquired may not be successful or continue to grow at the same rate as when operated independently or may require greater resources and investments than originally anticipated. The Intermex Acquisition could also result in the assumption of unknown or contingent liabilities, and, because Intermex operates in the same sector that we do, the Intermex Acquisition could also exacerbate a number of risks that currently apply to us. The occurrence of any of these events individually or in combination could materially and adversely affect our business, financial condition, results of operations and growth prospects.

Risks Relating to the Notes

We are a holding company that conducts all of our business through our subsidiaries. The debt and other liabilities of our subsidiaries will be effectively senior to the notes.

We conduct all of our business through our subsidiaries. Our cash flow and, consequently, our ability to pay interest and to service our debt, including the notes, are dependent upon the cash flow of our subsidiaries and the payment of funds to us by those subsidiaries in the form of loans, dividends or otherwise. Our subsidiaries are separate and distinct legal entities and will have no obligation, contingent or otherwise, to pay any amounts due on the notes or to make cash available for that purpose. In addition, many of our operating subsidiaries are highly regulated and may be subject to restrictions on their ability to pay dividends to us. These subsidiaries may use the earnings they generate, as well as their existing assets, to fulfill any existing or future direct debt service requirements.

S-6

The notes will be The Western Union Company’s senior unsecured obligations and will rank equally in right of payment with all of its existing and future senior unsecured obligations. The notes will be effectively junior to all existing and future indebtedness and other liabilities of our subsidiaries, which means that creditors of our subsidiaries will be paid from their assets before holders of the notes would have any claims to those assets. As of March 31, 2026, our subsidiaries had outstanding approximately $115 million of total indebtedness, including letters of credit and bank guarantees but excluding intercompany indebtedness, and may incur additional debt in the future. See “Description of the Notes—General—Ranking.”

There are no covenants in the indenture governing the notes relating to our ability to incur future indebtedness or pay dividends, and there are limited restrictions on our ability to engage in other activities, which could adversely affect our ability to pay our obligations under the notes.

The indenture governing the notes does not contain any financial covenants. The indenture permits us and, with respect to the notes, our subsidiaries, to incur additional debt, including, subject to certain requirements, secured debt. Because the notes are unsecured, in the event of any liquidation, dissolution, reorganization, bankruptcy or other similar proceeding regarding us, whether voluntary or involuntary, the holders of any of our secured debt will be entitled to receive payment to the extent of the assets securing that debt before we can make any payment with respect to the notes. If any of the foregoing events occurs, we cannot assure you that we will have sufficient assets to pay amounts due on our debt and the notes. As a result, you may receive less than you are entitled to receive or recover nothing if any liquidation, dissolution, reorganization, bankruptcy or other similar proceeding occurs.

The indenture does not limit our or our subsidiaries’ ability to issue or repurchase securities, pay dividends or engage in transactions with affiliates. Our ability to use our funds for numerous purposes may limit the funds available to pay our obligations under the notes.

There may not be public markets for the notes.

The notes constitute a new issue of securities with no established trading markets. The notes offered hereby will be a further issuance of, and will form a single series with, the existing notes. Any market that has developed for the existing notes may not be maintained. We do not intend to list the notes on any securities exchange or to include the notes in any automated quotation system. Accordingly, no markets for the notes may develop, and any markets that develop may not last. If the notes are traded, they may trade at a discount from their offering price, depending on prevailing interest rates, the market for similar securities, our performance and other factors. To the extent that active trading markets do not develop, you may not be able to resell your notes at their fair market value or at all.

The market prices of the notes may be volatile.

The market prices of the notes will depend on many factors, including, but not limited to, the following:

•

ratings on our debt securities assigned by rating agencies;

•

the time remaining until maturity of the notes;

•

the prevailing interest rates being paid by other companies similar to us;

•

our results of operations, financial condition and prospects; and

•

the condition of the financial markets.

The condition of the financial markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future, which could have an adverse effect on the market prices of the notes.

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

Unless we exercise our right to redeem the notes, we will be required to make an offer to repurchase the notes at a price equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to the date of

S-7

repurchase upon a “Change of Control Triggering Event.” A “Change of Control Triggering Event” will occur when (i) there is a “Change of Control” involving us and (ii) among other things, within a specified period in relation to the “Change of Control,” the notes are downgraded from an investment grade rating to below an investment grade rating by the following rating agencies or their successors or replacements: Moody’s and S&P. If we experience a “Change of Control Triggering Event,” there can be no assurance that we would have sufficient financial resources available to satisfy our obligations to repurchase the notes. Our failure to repurchase the notes as required would result in a default under the notes, which could have material adverse consequences for us and the holders of the notes. See “Description of the Notes—Change of Control.”

A holder may not be able to determine when a Change of Control Triggering Event has occurred and may not be able to require us to purchase its notes as a result of a change in the composition of the directors on our board of directors.

The definition of Change of Control includes a phrase relating to the direct or indirect sale, transfer, conveyance or other disposition, in one or a series of related transactions, of our assets and the assets of our subsidiaries substantially as an entirety or as an entirety, taken as a whole. Although there is a limited body of case law interpreting this phrase, there is no precise established definition of such phrase under applicable law.

Accordingly, the ability of a holder of the notes to require us to repurchase that holder’s notes as a result of the sale, transfer, conveyance or other disposition of less than all of our assets and the assets of our subsidiaries substantially as an entirety or as an entirety, taken as a whole, to one or more persons may be uncertain.

In addition, in interpreting a definition of “continuing directors,” a Delaware Chancery Court decision found that a board of directors may approve, for purposes of such definition, a slate of stockholder-nominated directors without endorsing them, or while simultaneously recommending and endorsing its own slate instead, as long as the approval is granted in good faith and in accordance with the board’s fiduciary duties. Accordingly, a holder may not be able to require us to repurchase the notes as a result of a change in the composition of the directors on our board of directors unless a court were to find that such approval was not granted in good faith or violated the board’s fiduciary duties. The Delaware Chancery Court also observed that certain provisions in indentures, such as continuing director provisions, could function to entrench an incumbent board of directors and would raise enforcement concerns if adopted in violation of a board’s fiduciary duties. If such a provision were found unenforceable, a holder would not be able to require us to repurchase its notes upon a Change of Control resulting from a change in the composition of our board of directors.

Our business, financial condition and results of operations could be harmed by adverse rating actions by credit rating agencies.

If our credit ratings are downgraded, or if they are placed under review or continue to have a negative outlook, our business, financial condition and results of operations could be adversely affected and perceptions of our financial strength could be damaged, which could adversely affect our relationships with our agents, particularly those agents that are financial institutions or post offices. In addition, an adverse credit rating by a rating agency, such as a downgrade or negative outlook, could result in regulators imposing additional capital and other requirements on us, including imposing restrictions on the ability of our regulated subsidiaries to pay dividends. Also, a significant downgrade could increase our costs of borrowing money, adversely affecting our business, financial condition and results of operations.

We may redeem the notes at our option and redemption may adversely affect your return on the notes.

We may redeem the notes at our option, in whole or in part, at any time and from time to time, at the respective prices specified in this prospectus supplement under “Description of the Notes—Optional Redemption.” If we redeem the notes at times when prevailing interest rates are relatively low, you may not be able to reinvest the redemption proceeds in a comparable security at an effective rate of interest as high as those of the notes.

USE OF PROCEEDS

Borrowings under the Term Loan Facility bear interest at a rate based on (i) a Secured Overnight Financing Rate adjusted for a 0.10% credit spread adjustment or (ii) the Adjusted Base Rate (as defined in the Term Loan Facility), plus an applicable margin. The interest rate of the Term Loan Facility was 5.0% as of March 31, 2026. The Term Loan Facility terminates on December 13, 2027.

We may issue unsecured commercial paper notes in an amount not to exceed $1.62 billion outstanding at any time, reduced to the extent of borrowings outstanding on our revolving credit facility. The commercial paper notes may have maturities of up to 397 days from date of issuance. The Company’s commercial paper borrowings as of March 31, 2026 had a weighted-average annual interest rate of approximately 4.0% and a weighted-average term of approximately 4 days.

DESCRIPTION OF THE NOTES

This prospectus supplement contains a description of the material terms of the notes but does not purport to be complete. This description of the notes supplements and, to the extent inconsistent therewith, replaces, the section entitled “Description of Debt Securities” included in the accompanying prospectus. You should read the accompanying prospectus and this prospectus supplement together for a more complete description of the indenture and the notes. Capitalized terms used in this “Description of the Notes” have the meanings specified in the indenture and are generally summarized in this section or under “Description of Debt Securities—Certain Definitions” in the accompanying prospectus. References to “we,” “us” and “our” in this “Description of the Notes” refer only to The Western Union Company and not any of its subsidiaries.

General

Principal, Maturity and Interest

We will issue the notes under a base indenture, dated as of November 17, 2006, between us and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee (the “Base Trustee”), as supplemented by supplemental indentures, dated as of September 6, 2007 and May 3, 2019, between us and the Base Trustee, and as further supplemented by a supplemental indenture, dated as of March 9, 2026, by and among us, U.S. Bank Trust Company, National Association, as series trustee (the “Trustee”), and the Base Trustee. We refer to the base indenture, as supplemented by the supplemental indentures, as the “indenture.”

The notes will be issued in book-entry form only in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The notes will mature on June 15, 2029. If the maturity date of the notes is not a Business Day then the principal amount of such notes plus accrued and unpaid interest thereon shall be paid on the next succeeding Business Day with the same effect as if payment were made on the maturity date, and no interest shall accrue for the maturity date, or thereafter.

The notes will bear interest at a rate of 4.750% per annum. The interest payment to be made on December 15, 2026 will include accrued and unpaid interest from and including March 9, 2026 to, but excluding the issue date of the notes, totaling approximately $ (assuming the issue date is , 2026). Such accrued interest must be paid by the purchasers of the notes offered hereby. Interest on the notes will accrue from March 9, 2026 or from the most recent date on which interest has been paid or provided for, payable semi-annually in arrears to holders of record at the close of business on June 1 or December 1 (whether or not a Business Day) immediately preceding the interest payment date on June 15 and December 15 of each year, beginning December 15, 2026. If any interest payment date for the notes falls on a day that is not a Business Day, then payment for the notes will be made on the next succeeding Business Day, without additional interest and with the same effect as if it were made on the originally scheduled date. Interest on the notes will be computed on the basis of a 360-day year of twelve 30-day months.

S-12

Interest Rate Adjustment

The interest rate payable on the notes will be subject to adjustments from time to time if Moody’s (or, if applicable, any Substitute Rating Agency (as defined below)) or S&P (or, if applicable, any Substitute Rating Agency), downgrades (or subsequently upgrades) the debt rating assigned to the notes, as set forth below.

If the rating from Moody’s or S&P (or, in either case if applicable, any Substitute Rating Agency) with respect to the notes (each, an “Applicable Rating Agency,” and collectively, the “Applicable Rating Agencies”) is decreased to a rating set forth in the immediately following table with respect to that Applicable Rating Agency, the per annum interest rate on the notes will increase from that set forth on the cover page of this prospectus supplement by the percentage set forth opposite that rating:


	Applicable Rating Agency
Rating Level	Moody’s*	S&P*	Percentage
1	Ba1	BB+		0.25	%
2	Ba2	BB		0.50	%
3	Ba3	BB-		0.75	%
4	B1 or below	B+ or below		1.00	%

*	Including the equivalent ratings of any Substitute Rating Agency

If at any time the interest rate on the notes has been adjusted upward as a result of a decrease in a rating by an Applicable Rating Agency and that Applicable Rating Agency subsequently increases its rating with respect to the notes to any of the threshold ratings set forth above, the per annum interest rate on such notes will be decreased such that the per annum interest rate equals the interest rate set forth on the cover page of this prospectus supplement plus the percentage set forth opposite the rating in effect immediately following the increase in the applicable table above; provided that if Moody’s or any Substitute Rating Agency subsequently increases its rating of the notes to “Baa3” (or its equivalent if with respect to any Substitute Rating Agency) or higher and S&P or any Substitute Rating Agency subsequently increases its rating of the notes to “BBB-” (or its equivalent if with respect to any Substitute Rating Agency) or higher, the interest rate on the notes will be decreased to the per annum interest rate of the notes set forth on the cover page of this prospectus supplement.

No adjustment in the interest rate of the notes shall be made solely as a result of an Applicable Rating Agency ceasing to provide a rating. If at any time less than two Applicable Rating Agencies provide a rating of the notes, we will use our commercially reasonable efforts to obtain a rating of the notes from another nationally recognized statistical rating organization, to the extent one exists, and if another nationally recognized statistical rating organization rates the notes (such organization, as certified by a resolution of our board of directors, a “Substitute Rating Agency”), for purposes of determining any increase or decrease in the per annum interest rate on the notes pursuant to the table above (a) such Substitute Rating Agency will be substituted for the last Applicable Rating Agency to provide a rating of the notes but which has since ceased to provide such rating, (b) the relative ratings scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by us and, for purposes of determining the applicable ratings included in the table above with respect to such Substitute Rating Agency, such ratings shall be deemed to be the equivalent ratings used by Moody’s and S&P in such table and (c) the per annum interest rate on the notes will increase or decrease, as the case may be, such that the interest rate equals the interest rate set forth on the cover page of the prospectus supplement plus the appropriate percentage, if any, set forth opposite the rating from such Substitute Rating Agency in the table above (taking into account the provisions of clause (b) above). For so long as (i) only one Applicable Rating Agency provides a rating of the notes, any increase or decrease in the interest rate of the notes necessitated by a reduction or increase in the rating by that Applicable Rating Agency shall be twice the applicable percentage set forth in the table above and (ii) no Applicable Rating Agency provides a rating of the notes, the interest rate on the notes will increase to, or remain at, as the case may be, 2.00% above the interest rate of the notes set forth on the cover page of this prospectus supplement.

S-13

Each adjustment required by any decrease or increase in a rating set forth above, whether occasioned by the action of Moody’s, S&P or any Substitute Rating Agency, shall be made independent of (and in addition to) any and all other adjustments. In no event shall (1) the per annum interest rate on the notes be reduced below the interest rate set forth on the cover page of this prospectus supplement or (2) the per annum interest rate on the notes exceed a rate that is 2.00% above the interest rate of the notes set forth on the cover page of this prospectus supplement.

Any interest rate increase or decrease described above on the notes will take effect from the first interest payment date following the date on which a rating change occurs that requires an adjustment in the interest rate of the notes. If Moody’s or S&P (or any Substitute Rating Agency) changes its rating of the notes more than once prior to any particular interest payment date, the last change by such agency prior to such interest payment date will control for purposes of any interest rate increase or decrease with respect to the notes described above relating to such Applicable Rating Agency’s action.

The interest rate on the notes will permanently cease to be subject to any adjustment described above (notwithstanding any subsequent decrease in the ratings by any Applicable Rating Agency) if the notes become rated “A3” (or its equivalent) or higher by Moody’s (or any Substitute Rating Agency) and “A-” (or its equivalent) or higher by S&P (or any Substitute Rating Agency), or one of those ratings if only rated by one Applicable Rating Agency, in each case with a stable or positive outlook.

Ranking

The notes will be our senior unsecured obligations and rank equally in right of payment with our other existing and future senior unsecured obligations.

We conduct all of our operations through our subsidiaries. Our rights and the rights of our creditors, including the holders of the notes, to participate in the distribution of assets of any of our subsidiaries upon the liquidation or reorganization of that subsidiary or otherwise will be subject to the prior claims of the subsidiary’s creditors, except to the extent that we may be a creditor with recognized claims against the subsidiary. However, the notes will be obligations exclusively of The Western Union Company and will not be guaranteed by any of our subsidiaries. As a result, the notes will be effectively junior to all existing and future indebtedness and other obligations of our subsidiaries, which means that creditors of our subsidiaries will be paid from their assets before holders of the notes would have any claims to those assets. As of March 31, 2026, our subsidiaries had outstanding approximately $115 million of total indebtedness, including letters of credit and bank guarantees but excluding intercompany indebtedness.

The indenture does not limit the amount of debt securities or any other debt (whether secured or unsecured or whether subordinated or unsubordinated) which we or, with respect to the notes, our subsidiaries may incur. However, the indenture provides that neither we nor any of our Restricted Subsidiaries (as defined under “Description of Debt Securities—Certain Definitions” in the accompanying prospectus) may subject certain of our property or assets to certain encumbrances unless the notes are secured equally and ratably with or prior to that other secured Indebtedness. Certain other covenants are applicable to the notes as described in the accompanying prospectus. See “Description of Debt Securities—Certain Covenants” in the accompanying prospectus.

No Sinking Fund

The notes will not be entitled to any sinking fund.

S-14

Issuance of Additional Notes

In addition to the notes, we may issue from time to time other series of debt securities under the indenture consisting of debentures, notes or other evidences of indebtedness that are separate from and independent of the notes. The indenture does not limit the amount of debt securities or any other debt (whether secured or unsecured or whether subordinated or unsubordinated) which we or our subsidiaries may incur.

We may from time to time, without the consent of, or notice to, the holders of the notes, reopen the series of debt securities of which the notes are a part and issue additional notes having the same ranking and the same interest rate, maturity and other terms as the notes, except for the public offering price and the issue date and, if applicable, the initial interest accrual date and the initial interest payment date. Any such additional notes having similar terms, together with the notes, will constitute a single series of debt securities under the indenture. If, however, any such additional notes are not fungible with the notes for U.S. federal income tax purposes, the additional notes will have a separate CUSIP number. No such additional notes may be issued if an Event of Default has occurred and is continuing with respect to the series of debt securities of which such notes are a part. Unless the context otherwise requires, for all purposes of the indenture and this “Description of the Notes,” references to the notes include any additional notes of the same series actually issued.

Payment and Paying Agents

We will maintain in the place of payment for the notes an office or agency where the notes may be presented or surrendered for payment or for registration of transfer or exchange and where holders may serve us with notices and demands in respect of the notes and the indenture.

We will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If we fail to maintain any required office or agency or fail to furnish the Trustee with the address of such office or agency, presentations, surrenders, notices and demands may be made or served at the corporate trust office of the Trustee. We have appointed the Trustee as our agent to receive all presentations, surrenders, notices and demands with respect to the notes.

Optional Redemption

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

plus, in either case, unpaid interest accrued thereon to, but not including, the redemption date.

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

S-15

The Treasury Rate shall be determined by The Western Union 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) (“H.15 TCM”). In determining the Treasury Rate, The Western Union 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 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, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third business day preceding the redemption date H.15 TCM is no longer published, The Western Union 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 Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, The Western Union Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, The Western Union 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 Western Union Company’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. The Trustee shall not be responsible or liable for determining, confirming or verifying the redemption price.

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 the 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 deems appropriate and fair. No notes 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. A new note of the same series 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. For so long as the notes are held by DTC (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the applicable depositary.

S-16

Unless The Western Union 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.

Change of Control

If a Change of Control Triggering Event occurs with respect to the notes, unless we have exercised our right to redeem the notes as described above, we will be required to make an offer (a “Change of Control Offer”) to each holder to repurchase all or any part (equal to $2,000 and integral multiples of $1,000 in excess thereof) of that holder’s notes on the terms set forth in such notes. In a Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of notes repurchased, plus accrued and unpaid interest, if any, on the notes repurchased to, but not including, the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at our option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed (or sent electronically in accordance with applicable DTC procedures) to holders of the notes, with a copy to the Trustee, describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the notes on the date specified in the notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is mailed or sent (a “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 Triggering Event occurring on or prior to the Change of Control Payment Date.

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

•

accept for payment all notes or portions of notes properly tendered pursuant to the Change of Control Offer and not withdrawn;

•

deposit with the paying agent an amount equal to the Change of Control Payment in respect of all notes or portions of notes properly tendered and not withdrawn; and

•

deliver or cause to be delivered to the Trustee the notes properly accepted together with an officers’ certificate stating the aggregate principal amount of notes or portions of notes being repurchased.

We will not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and the third party purchases all notes properly tendered and not withdrawn under its offer. In addition, we will not repurchase 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.

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

If holders of not less than 90% in aggregate principal amount of the outstanding notes properly tender and do not withdraw such notes in a Change of Control Offer (or an offer made by a third party as described above) and we, or any third-party making an offer in lieu of us, as described above, purchase all of the notes properly tendered and not withdrawn by such holders, we or the third party making such offer will have the right, upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or offer by such third party described above, to redeem all notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment.

S-17

If a Change of Control Offer is made, there can be no assurance that we will have available funds sufficient to make the Change of Control Payment for all of the notes that may be tendered for repurchase.

For purposes of the Change of Control Offer provisions of the notes, the following terms will be applicable:

“Change of Control” means the occurrence of any 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 more series of related transactions, of our assets and the assets of our subsidiaries substantially as an entirety or as an entirety, taken as a whole, to any person, other than our company 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 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 or other voting stock into which our voting stock is reclassified, consolidated, exchanged or changed in such transaction, measured by voting power rather than number of shares; (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 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 outstanding voting stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; (4) the first day on which a majority of the members of our board of directors are not continuing directors; or (5) the adoption of a plan relating to our liquidation or dissolution. Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control under clause (2) or (3) above if (i) we become a direct or indirect wholly owned subsidiary of a holding company and (ii)(A) the direct or indirect holders of the voting stock of such holding company immediately following that transaction are substantially the same as the holders of our voting stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the voting stock of such holding company. The term “person,” as used in this definition, has the meaning given thereto in Section 13(d)(3) of the Exchange Act.

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

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

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

“Moody’s” means Moody’s Investors Service, Inc., and its successors.

“Rating Agencies” means (1) each of Moody’s and S&P; and (2) if any or both of Moody’s or S&P ceases to rate the notes or fails to make a rating of the notes publicly available, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) under the Exchange Act selected by us (as certified by a resolution of our board of directors) as a replacement agency for Moody’s or S&P, or both of them, as the case may be.

S-18

“Rating Event” means the rating on the notes is lowered by all of the Rating Agencies from an Investment Grade Rating to below an Investment Grade Rating, in any case on any day during the period (which period will be extended so long as the rating of the notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies) commencing upon the first public notice by us of the occurrence of a Change of Control or our intention to effect a Change of Control and ending 60 days following the consummation of the Change of Control; provided, however, that a Rating 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 Rating Event for purposes of the definition of Change of Control Triggering Event) if any of the Rating Agencies does not announce or publicly confirm or inform us that the reduction in ratings 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 been consummated at the time of the Rating Event).

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

“voting stock” means, with respect to any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date, 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.

Our obligation to purchase the notes following a Change of Control Triggering Event is subject to the provisions described in the section titled “Discharge, Legal Defeasance and Covenant Defeasance” in this prospectus supplement.

Discharge, Legal Defeasance and Covenant Defeasance

We may be discharged from all of our obligations with respect to the outstanding notes, be discharged from our obligations with respect to the notes (except as otherwise specified in the indenture) or be released from our obligation to comply with the provisions of the indenture with respect to the notes as described under “Description of Debt Securities—Discharge, Legal Defeasance and Covenant Defeasance” in the accompanying prospectus.

The Trustee Under the Indenture

We maintain ordinary banking relationships and, from time to time, obtain credit facilities and lines of credit with a number of banks, including the Trustee, U.S. Bank Trust Company, National Association. The Trustee assumes no responsibility or liability for the accuracy or completeness of the information concerning us or our affiliates or any other party contained in this prospectus supplement or the accompanying prospectus 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. Neither the Trustee (in any of its capacities) nor any paying agent shall be responsible or liable for monitoring our rating status, making any request upon any Rating Agency, or determining whether any Change of Control Triggering Event has occurred. The transferor of any note shall provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code (as defined under “Material U.S. Federal Income Tax Considerations” below). The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information. In connection with any proposed exchange of a certificated note for a global note, we or DTC shall be required to provide or cause to be provided to the Trustee all information necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code. The Trustee may rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

S-19

Governing Law

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

Other Terms of the Notes

With respect to the notes, the term “Financing Lease” means any lease of property, real or personal, the obligations of the lessee in respect of which are required in accordance with GAAP as it exists on , 2026 to be accounted for as a finance lease as defined within Accounting Standards Codification 842, Leases.

Book-Entry, Delivery and Form

Global Notes

We will issue the notes in the form of one or more global notes in definitive, fully registered, book-entry form. The global notes will be deposited with or on behalf of DTC and registered in the name of Cede & Co. (as nominee of DTC), or such other name as may be requested by an authorized representative of DTC.

DTC, Clearstream and Euroclear

Beneficial interests in the global notes will be represented through book-entry accounts of financial institutions acting on behalf of beneficial owners as direct and indirect participants in DTC. Investors may hold interests in the global notes through either DTC (in the United States), or Clearstream or Euroclear (in Europe) either directly if they are participants in such systems or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their U.S. depositaries, which in turn will hold such interests in customers’ securities accounts in the U.S. depositaries’ names on the books of DTC.

DTC has advised us as follows:

•

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 under Section 17A of the Exchange Act.

•

DTC holds securities that its participants deposit with DTC and facilitates the post-trade settlement among participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

•

Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and other organizations.

•

DTC is owned by a number of its direct participants.

•

Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

•

The rules applicable to DTC and its direct and indirect participants are on file with the SEC.

Clearstream is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between its customers through electronic book-entry changes in accounts of its customers, thereby eliminating the need for physical movement of certificates. Clearstream provides to its customers, among other things, services for

S-20

safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector and the Central Bank of Luxembourg. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and other organizations and may include the underwriter. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream customer either directly or indirectly.

The Euroclear System was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV (the “Euroclear Operator”). Euroclear participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriter. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly.

The Euroclear Operator is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking and Finance Commission. As the operator of a securities settlement system, the Euroclear Operator is also overseen by the National Bank of Belgium.

We have provided the descriptions of the operations and procedures of DTC, Clearstream and Euroclear in this prospectus supplement solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of us, the underwriter or the Trustee (in any of its capacities) takes any responsibility for these operations or procedures, and you are urged to contact DTC, Clearstream and Euroclear or their participants directly to discuss these matters.

We expect that under procedures established by DTC:

•

upon deposit of the global notes with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by the underwriter with portions of the principal amounts of the global notes; and

•

ownership of the notes will be shown on, and the transfer of ownership thereof will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.

The laws of some jurisdictions may require that purchasers of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer interests in the notes represented by a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in notes represented by a global note to pledge or transfer those interests to persons or entities that do not participate in DTC’s system, or otherwise to take actions in respect of such interest, may be affected by the lack of a physical definitive security in respect of such interest.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee will be considered the sole owner or holder of the notes represented by that global note for all purposes under the indenture and under the notes. DTC has no knowledge of the actual beneficial owners of the notes; DTC’s

S-21

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

Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the notes of a series are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each direct participant in such series to be redeemed.

In any case where a vote may be required with respect to the notes, neither DTC nor its nominee will consent or vote with respect to such notes. Under its usual procedures DTC mails an omnibus proxy to Western Union as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts interests in the notes are credited on the record date (identified in the listing attached to the omnibus proxy).

Neither we nor the Trustee (in any of its capacities) will have any responsibility or liability for any aspect of the records relating to or payments made on account of notes by DTC, Clearstream or Euroclear, or for maintaining, supervising or reviewing any records of those organizations relating to the notes.

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

Distributions on the notes held beneficially through Clearstream will be credited to cash accounts of its customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

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

S-22

Distributions on the notes held beneficially through Euroclear will be credited to the cash accounts of its participants in accordance with the Terms and Conditions, to the extent received by the U.S. depositary for Euroclear.

In any case where we have made a tender offer for the purchase of any notes, a beneficial owner must give notice through a participant to a tender agent to elect to have its notes purchased or tendered. The beneficial owner must deliver notes by causing the direct participants to transfer the participant’s interest in the notes, on DTC’s records, to a tender agent. The requirement for physical delivery of notes in connection with an optional tender or a mandatory purchase is satisfied when the ownership rights in the notes are transferred by direct participants on DTC’s records and followed by a book-entry credit of tendered notes to the tender agent’s DTC account.

Clearance and Settlement Procedures

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules and will be settled in immediately available funds. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, as applicable, and will be settled using the procedures applicable to conventional EuroBonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving the notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream customers and Euroclear participants may not deliver instructions directly to their U.S. depositaries.

Because of time-zone differences, credits of the notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in the notes settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of the notes by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures to facilitate transfers of the notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

The information in this section regarding DTC, Clearstream and Euroclear and their book-entry systems has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy of that information.

S-23

Certificated Notes

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

•

DTC notifies us that it is no longer willing or able to act as a depositary for such global note or ceases to be a clearing agency registered under the Exchange Act and we have not appointed a successor depositary within 90 days of that notice or becoming aware that DTC is no longer so registered;

•

an Event of Default has occurred and is continuing, and DTC requests the issuance of certificated notes; or

•

we determine not to have the notes represented by a global note.

Neither we nor the Trustee (in any of its capacities) will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the notes. We and the Trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee for all purposes, including with respect to the registration and delivery, and the respective principal amounts, of the certificated notes to be issued.

S-24

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a discussion of the material U.S. federal income tax consequences of the ownership and disposition of the notes to beneficial owners of the notes. This discussion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), the U.S. Treasury regulations promulgated thereunder, administrative pronouncements and judicial decisions, all as of the date hereof and all of which are subject to change, possibly on a retroactive basis.

This discussion applies only to beneficial owners that acquire the notes in connection with their initial issuance at their initial offering price and hold the notes as “capital assets” within the meaning of section 1221 of the Code. This discussion does not address all aspects of U.S. federal income taxation that might be important to particular investors in light of their individual circumstances or the U.S. federal income tax consequences applicable to special classes of taxpayers, such as banks and other financial institutions, insurance companies, real estate investment trusts, regulated investment companies, tax-exempt organizations, partnerships (or entities properly classified as partnerships for U.S. federal income tax purposes) or other pass-through entities, dealers in securities, traders in securities that elect to use a mark-to-market method of accounting, persons liable for U.S. federal alternative minimum tax, U.S. Holders (as defined below) whose functional currency is not the U.S. Dollar, former citizens or residents of the United States, persons holding the notes as part of a hedging or conversion transaction or a straddle, persons required to conform the timing of the income accruals with respect to the notes to that on their applicable financial statements and persons holding the 2026 Notes. The discussion does not address any federal estate or gift, foreign, state, local or non-income tax consequences of the ownership or disposition of the notes to beneficial owners of the notes.

As used in this prospectus supplement, the term “U.S. Holder” means a beneficial owner of a note that is for U.S. federal income tax purposes:

•

a citizen or individual resident of the United States;

•

a corporation (or other entity properly classified as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States, any state within the United States, or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust, if (i) a U.S. court is able to exercise primary supervision over the trust’s administration and one or more “United States persons” (as defined in the Code) have the authority to control all substantial decisions of the trust, or (ii) in the case of a trust that was treated as a domestic trust under the laws in effect before 1997, a valid election is in place under applicable U.S. Treasury regulations to treat such trust as a domestic trust.

The term “Non-U.S. Holder” means any beneficial owner of a note that is not a U.S. Holder and is not a partnership or other entity properly classified as a partnership for U.S. federal income tax purposes. For the purposes of this prospectus supplement, U.S. Holders and Non-U.S. Holders are referred to collectively as “Holders.”

If a partnership or other entity properly classified as a partnership for U.S. federal income tax purposes is a beneficial owner of a note, the tax treatment of a partner will generally depend upon the status of the partner and the activities of the entity. Such entities and partners in such entities should consult their own tax advisors about the U.S. federal income and other tax consequences of the ownership and disposition of a note.

Holders should consult their own tax advisors regarding the application of the U.S. federal income tax laws to their particular situations and the consequences under federal estate or gift tax laws, as well as foreign, state or local laws and tax treaties, and the possible effects of changes in tax laws.

Qualified Reopening

S-25

the same issue as the original debt instruments for U.S. federal income tax purposes. Under such treatment, the notes offered hereby will have the same issue date and issue price as the existing notes. Similarly, because the existing notes were not issued with OID for U.S. federal income tax purposes, the new notes offered hereby should not be treated as having been issued with OID. The remainder of this discussion assumes that the notes offered hereby will be treated as issued in a qualified reopening as described above.

Pre-Acquisition Accrued Interest

A portion of the price paid for the new notes offered hereby is attributable to the amount of interest accrued from March 9, 2026 (“pre-acquisition accrued interest”). To the extent a portion of a U.S. Holder’s purchase price is allocable to pre-acquisition accrued interest, a portion of the first stated interest payment equal to the amount of such pre-acquisition accrued interest may be treated as a nontaxable return of such pre-acquisition accrued interest to the U.S. Holder. If so, the amount treated as a return of pre-acquisition accrued interest will reduce a U.S. Holder’s adjusted tax basis in such new notes offered hereby by a corresponding amount. Any pre-acquisition accrued interest paid to a Non-U.S. Holder, however, may be subject to withholding of U.S. federal income tax if the requirements described below under “U.S. Federal Income Taxation of Non-U.S. Holders—Payments of Interest” or “U.S. Federal Income Taxation of Non-U.S. Holders—Foreign Account Tax Compliance” are not met.

U.S. Federal Income Taxation of U.S. Holders

Payments of Interest

Interest on notes beneficially owned by a U.S. Holder generally will be taxable as ordinary interest income at the time payments are accrued or are received in accordance with the U.S. Holder’s regular method of accounting for U.S. federal income tax purposes.

Effect of Certain Contingencies and Options

In certain circumstances, we may be obligated to pay a change of control premium on the notes (as described above under “Description of the Notes—Change of Control”). This obligation may implicate the provisions of U.S. Treasury regulations relating to “contingent payment debt instruments.” We intend to take the position that the contingency that such payment will be made is “remote” or “incidental” (within the meaning of applicable U.S. Treasury regulations) and therefore that the notes are not subject to the rules governing contingent payment debt instruments. Although not entirely clear, under our position any change of control premium likely will be taxable to a U.S. Holder as capital gain rather than ordinary income when received or accrued, according to such U.S. Holder’s method of accounting for U.S. federal income tax purposes.

In addition, in certain circumstances, if the debt ratings on the notes change, we may be obligated to pay additional interest on the notes (as described above under “Description of the Notes—General—Interest Rate Adjustment”). This obligation may also implicate the provisions of U.S. Treasury regulations relating to “contingent payment debt instruments.” We believe (and intend to take the position) that the contingency that such additional interest will be paid is “remote” or “incidental” (within the meaning of applicable U.S. Treasury regulations) and therefore will not cause the notes to be subject to the rules governing contingent payment debt instruments.

If our position were found to be incorrect and the notes were determined to be contingent payment debt instruments, a U.S. Holder would, among other things, be required to accrue interest income at a “comparable yield,” which likely would be higher than the stated interest rate on the notes, and would cause any gain from the sale or other disposition of a note to be treated as ordinary interest income, rather than capital gain. This discussion assumes that the notes will not be subject to the rules governing “contingent payment debt instruments.”

S-26

Sale, Exchange or Redemption of the Notes

Upon the sale, exchange, redemption or other taxable disposition of a note, a U.S. Holder generally will recognize gain or loss equal to the difference, if any, between (i) the amount realized upon the sale, exchange, redemption or other taxable disposition, other than amounts attributable to accrued and unpaid interest (which will be taxed as ordinary interest income to the extent such interest has not been previously included in income), and (ii) the U.S. Holder’s adjusted tax basis in the note. The amount realized by a U.S. Holder is the sum of cash plus the fair market value of all other property received on such sale, exchange, redemption or other taxable disposition. A U.S. Holder’s adjusted tax basis in a note generally will be equal to the amount paid by such U.S. Holder for the note.

Subject to the discussion above under “—Effect of Certain Contingencies and Options,” the gain or loss a U.S. Holder recognizes on the sale, exchange, redemption or other taxable disposition of a note generally will be capital gain or loss. Such gain or loss generally will be long-term capital gain or loss if a U.S. Holder has held the note for more than 12 consecutive months. For non-corporate U.S. Holders, long-term capital gains are currently taxed at a lower rate than ordinary income. The deductibility of capital losses is subject to limitations. A U.S. Holder should consult its own tax advisor regarding the deductibility of capital losses in its particular circumstances.

Tax on Net Investment Income

A 3.8% tax will be imposed on a portion or all of the net investment income of certain individuals with a modified adjusted gross income of over $200,000 ($250,000 in the case of joint filers) and on the undistributed net investment income of certain estates and trusts. For these purposes, “net investment income” generally will include interest (including interest paid with respect to a note), dividends, annuities, royalties, rents, net gain attributable to the disposition of property not held in a trade or business (including net gain from the sale, exchange, redemption or other taxable disposition of a note) and certain other income, but will be reduced by any deductions properly allocable to such income or net gain. U.S. Holders should consult their own tax advisors regarding the implications of the net investment income tax in their particular circumstances.

Backup Withholding and Information Reporting

In general, a U.S. Holder that is not an “exempt recipient” will be subject to U.S. federal backup withholding at the applicable rate with respect to payments on its notes and the proceeds of a sale, exchange, redemption or other taxable disposition of its notes, unless the U.S. Holder provides its taxpayer identification number to the paying agent and certifies, under penalties of perjury, that it is not subject to backup withholding on an Internal Revenue Service (the “IRS”) Form W-9 (Request for Taxpayer Identification Number and Certification) or a suitable substitute 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 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 notes made to, and the proceeds of a sale or other taxable disposition by, a U.S. Holder that is not an exempt recipient generally will be subject to information reporting requirements.

U.S. Federal Income Taxation of Non-U.S. Holders

Payments of Interest

Subject to the discussion below under “—Backup Withholding and Information Reporting” and “—Foreign Account Tax Compliance,” a Non-U.S. Holder generally will not be subject to U.S. federal withholding tax on interest paid on its notes so long as:

•

the Non-U.S. Holder does not, actually or constructively, own 10% or more of the total combined voting power of all of our stock entitled to vote;

S-27

•

the Non-U.S. Holder is not a “controlled foreign corporation” that is related to us, actually or by attribution, through stock ownership; and

•

either (i) the Non-U.S. Holder certifies under penalties of perjury on IRS Form W-8BEN (Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals)) or Form W-8BEN-E (Certificate of Status of Beneficial Owner for United States Tax Withholding and Reporting (Entities)) or a suitable substitute form that it is not a United States person (as defined in the Code), and provides its name, address, and U.S. taxpayer identification number, if any, or (ii) a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and holds the notes on behalf of the Non-U.S. Holder certifies under penalties of perjury that the certification referred to in clause (i) has been received from the Non-U.S. Holder, and furnishes a copy thereof

Except as described below under “—Effectively Connected Income,” a Non-U.S. Holder that does not qualify for exemption from withholding as described above generally will be subject to withholding of U.S. federal income tax at a rate of 30% on payments of interest on the notes. A Non-U.S. Holder may be entitled to the benefits of an income tax treaty under which interest on the notes is subject to a reduced rate of U.S. withholding tax or is exempt from U.S. withholding tax, in which case the Non-U.S. Holder will be required to furnish a properly completed and executed IRS Form W-8BEN or Form W-8BEN-E claiming the reduction or exemption and comply with any other applicable procedures.

Special rules regarding exemption from, or reduced rates of, U.S. withholding tax may apply in the case of notes held by partnerships or certain types of trusts. Partnerships and trusts that are prospective purchasers should consult their tax advisors regarding special rules that may be applicable in their particular circumstances.

Sale, Exchange or Redemption of the Notes

Generally, gain recognized by a Non-U.S. Holder on the sale, exchange, redemption or other taxable disposition of a note will not be subject to U.S. federal income or withholding tax, unless:

•

the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if a treaty applies, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States); or

•

the Non-U.S. Holder is an individual who is present in the United States for 183 days or more during the taxable year, and certain other conditions are met.

Effectively Connected Income

If interest, gain or other income recognized by a Non-U.S. Holder on a note is “effectively connected” with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if a treaty applies, is attributable to a permanent establishment or fixed base maintained by the Non-U.S. Holder in the United States), the Non-U.S. Holder will not be subject to the withholding tax discussed above, although the Non-U.S. Holder will be required to provide a properly completed and executed IRS Form W-8ECI (Certificate of Foreign Person’s Claim That Income Is Effectively Connected With the Conduct of a Trade or Business in the United States) to avoid the withholding. Although it will not be subject to the withholding tax, the Non-U.S. Holder generally will be subject to U.S. federal income tax on such interest, gain or other income as if it were a United States person (as defined in the Code). In addition to such U.S. federal income tax, if the Non-U.S. Holder is a corporation, it may be subject to an additional 30% (or such lower rate as may be provided for under an applicable treaty) branch profits tax.

Backup Withholding and Information Reporting

The amount of interest on a note that is paid to a Non-U.S. Holder and the tax, if any, withheld with respect to such interest must be reported annually to the IRS. These reporting requirements apply regardless of whether

S-28

U.S. withholding tax on such payments was reduced or eliminated by any applicable tax treaty or otherwise. Copies of the information returns reporting those payments and the amounts withheld may also be made available to the tax authorities in the country where a Non-U.S. Holder is a resident under the provisions of an applicable income tax treaty or agreement.

Under some circumstances, U.S. Treasury regulations require backup withholding and additional information reporting on payments of interest and other “reportable payments.” Such backup withholding and additional information reporting will not apply to payments on the notes made to a Non-U.S. Holder if the certification described above under “—Payments of Interest” or “—Effectively Connected Income” is received from the Non-U.S. Holder.

Backup withholding and information reporting generally will not apply to payments of proceeds from the sale or other disposition of a note made to a Non-U.S. Holder by or through the foreign office of a broker. However, information reporting requirements, and possibly backup withholding, will apply if such broker is, for U.S. federal income tax purposes, a United States person (as defined in the Code) or has certain other enumerated connections with the United States, unless such broker has documentary evidence in its records that the Non-U.S. Holder is not a United States person (as defined in the Code) and certain other conditions are met, or the Non-U.S. Holder otherwise establishes an exemption. Payments of proceeds from the sale or other disposition of a note made to a Non-U.S. Holder by or through the U.S. office of a broker are subject to information reporting and backup withholding at the applicable rate unless the Non-U.S. Holder certifies, under penalties of perjury, that it is not a United States person (as defined in the Code) and satisfies certain other conditions or otherwise establishes an exemption. The certification procedures described above with respect to interest in the preceding paragraph will avoid backup withholding on payments of proceeds from the sale or other disposition of a note. Backup withholding is not an additional tax. A Non-U.S. Holder may obtain a refund or credit against its U.S. federal income tax liability of any amounts withheld under the backup withholding rules, provided the required information is furnished to the IRS in a timely manner.

Non-U.S. Holders should consult their tax advisors regarding the application of information reporting and backup withholding in their particular situations, the availability of an exemption therefrom, and the procedures for obtaining such an exemption, if available.

Foreign Account Tax Compliance

The Foreign Account Tax Compliance Act and related IRS guidance (“FATCA”) impose a 30% U.S. withholding tax on certain payments which currently include interest payments on the notes made to certain non-United States entities that fail to take required steps to provide information regarding their “United States accounts” or their direct or indirect “substantial United States owners,” as applicable, or to make a required certification that they have no such accounts or owners. Withholding may also apply to payments of proceeds of sales or redemptions of the notes, although under proposed regulations (the preamble to which specifies that taxpayers are permitted to rely on them pending finalization) no withholding will apply on payments of gross proceeds. We will not be obligated to make any “gross up” or additional payments in respect of amounts withheld on the notes if we determine that we must so withhold in order to comply with FATCA (including the application of an applicable intergovernmental agreement). Prospective investors should consult their own tax advisors regarding FATCA and whether it may be relevant to their ownership and disposition of the notes.

The U.S. federal income tax discussion set forth above is included for general information only and may not be applicable depending upon a Holder’s particular situation. Prospective purchasers of notes should consult their own tax advisors with respect to the tax consequences to them of the ownership and disposition of the notes, including the tax consequences under state, local, estate, foreign and other tax laws and tax treaties and the possible effects of changes in U.S. or other tax laws.

UNDERWRITING

Wells Fargo Securities, LLC (the “underwriter”) is the book-running manager of the offering. Subject to the terms and conditions of an underwriting agreement between us and the underwriter, the underwriter has agreed to purchase from us, and we have agreed to sell to the underwriter, the principal amount of notes listed opposite its name below:


Underwriter		Principal Amount of Notes
Wells Fargo Securities, LLC		$

Total		$

The underwriting agreement provides that the obligations of the underwriter to purchase the notes offered hereby are subject to certain conditions and that the underwriter will purchase all of the notes offered by this prospectus supplement if any of the notes are purchased.

We have been advised by the underwriter that the underwriter proposes to offer the notes directly to the public at the public offering price set forth on the cover page of this prospectus supplement and may offer notes to certain dealers at such price less a concession not in excess of % of the principal amount of the notes. The underwriter may allow, and such dealers may reallow, a concession not in excess of % of the principal amount of the notes to certain other dealers. After the initial public offering, the underwriter may change the offering price and other selling terms.

We estimate that our total expenses of this offering to be paid by us, excluding the underwriting discount will be $ .

We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments the underwriter may be required to make in respect of any of these liabilities.

The notes are a new issue of securities with no established trading markets. The notes will not be listed on any securities exchange or quoted on any automated dealer quotation system. The underwriter may make markets in the notes after completion of the offering, but will not be obligated to do so and may discontinue any market-making activities at any time without notice. No assurance can be given as to the liquidity of the trading markets for the notes or that active trading markets for the notes will develop. If active trading markets for the notes do not develop, the market price and liquidity of the notes may be adversely affected.

In connection with the offering of the notes, the underwriter may engage in transactions that stabilize, maintain or otherwise affect the price of the notes. Specifically, the underwriter may overallot in connection with the offering, creating a short position. In addition, the underwriter may bid for, and purchase, the notes in the open market to cover short positions or to stabilize the price of the notes. Any of these activities may stabilize or maintain the market price of the notes above independent market levels, but no representation is made hereby that the underwriter will engage in any of those transactions or of the magnitude of any effect that the transactions described above may have on the market price of the notes. The underwriter will not be required to engage in these activities, and if they engage in these activities, they may end any of these activities at any time without notice.

We expect to deliver the notes against payment on or about , 2026, which is the business day following the date of this prospectus supplement (such settlement being referred to as “T+ ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes more than one business day before the settlement date will be required, by virtue of the fact that the notes

S-30

initially settle in T+ , to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes more than one business day before the settlement date should consult their advisors.

Other Relationships

The underwriter and its affiliates have from time to time provided, and may provide in the future, investment banking, commercial banking and other financial services to us and our affiliates, for which they have received and may continue to receive customary fees and commissions. Affiliates of the underwriter in this offering are also lenders under our term and revolving credit facilities. We believe that the fees and commissions paid in respect of participation in the credit facilities were customary for borrowers with a credit profile similar to ours, for a similar-size financing and for borrowers in our industry.

The underwriter and its affiliates have engaged in, and may in the future engage in, investment banking and other commercial dealings in the ordinary course of business with us or our affiliates. They have received, or may in the future receive, customary fees and commissions for these transactions.

In addition, in the ordinary course of their business activities, the underwriter and its affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If the underwriter or its affiliates have a lending relationship with us, the underwriter or its affiliates routinely hedge, and the underwriter may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, the underwriter and its 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 underwriter and its affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

Selling Restrictions

European Economic Area

The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area (“EEA”). For these purposes, (a) the expression “retail investor” means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended (“MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97, as amended, where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in Regulation (EU) 2017/1129, as amended (the “EU Prospectus Regulation”); and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes. Consequently, no key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

This prospectus supplement and the accompanying prospectus have been prepared on the basis that any offer of the notes in any Member State of the EEA (each, a “Relevant State”) will be made pursuant to an exemption under the EU Prospectus Regulation from the requirement to produce a prospectus for offers of notes.

S-31

Accordingly, any person making or intending to make any offer in that Relevant State of the notes which are the subject of the offering contemplated by this prospectus supplement and the accompanying prospectus may only do so in circumstances in which no obligation arises for us or the underwriter to produce a prospectus pursuant to Article 3 of the EU Prospectus Regulation in relation to such offer. Neither we nor the underwriter have authorized, nor do we or they authorize, the making of any offer of notes in circumstances in which an obligation arises for us or the underwriter to publish a prospectus for such offer.

Consequently, no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law in the United Kingdom (the “U.K. PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the U.K. PRIIPs Regulation.

Such solicitation shall be subject to the condition that qualified institutional investors (as defined under the FIEA, “QIIs”) who desire to acquire the notes shall be made aware that they shall not transfer the notes to anyone other than other QIIs.

ABOUT THIS PROSPECTUS

This prospectus is part of an automatic shelf registration statement that we filed with the Securities and Exchange Commission, or “SEC,” as a “well-known seasoned issuer” as defined in Rule 405 under the Securities Act of 1933, as amended, or the “Securities Act.” Under the automatic shelf process, we may, over time, sell the debt securities described in this prospectus or in any applicable prospectus supplement in one or more offerings. The exhibits to our registration statement contain the full text of certain agreements and other important documents we have summarized in this prospectus. Since these summaries may not contain all the information that you may find important in deciding whether to purchase the debt securities we offer, you should review the full text of these documents. The registration statement and the exhibits can be obtained from the SEC as indicated under the heading “Where You Can Find More Information.”

This prospectus only provides you with a general description of the debt securities we may offer. Each time we sell debt securities, we will provide a prospectus supplement that contains specific information about the terms of those debt securities. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement, together with the documents incorporated and deemed to be incorporated by reference in this prospectus and the additional information described below under the heading “Where You Can Find More Information.”

When we refer to “Western Union,” the “company,” “we,” “us” or “our” in this prospectus we mean The Western Union Company and its consolidated subsidiaries, unless the context requires otherwise.

Our principal executive offices are located at 7001 East Belleview Avenue, Denver, Colorado 80237. Our main telephone number is (866) 405-5012.

WHERE YOU CAN FIND MORE INFORMATION

We file annual, quarterly and current reports, proxy statements and other information with the SEC. The SEC allows us to “incorporate by reference” into this prospectus the information we file with the SEC, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to be part of this prospectus, and information that we file later with the SEC will automatically update and supersede this information.

USE OF PROCEEDS

Unless otherwise specified in a prospectus supplement accompanying this prospectus, the net proceeds from the sale of debt securities to which this prospectus relates will be used for general corporate purposes. General corporate purposes may include, among other uses, repayment of debt, repurchases of stock, acquisitions, additions to working capital, capital expenditures and investments in our subsidiaries. Net proceeds may be invested prior to use.

DESCRIPTION OF DEBT SECURITIES

We will issue the debt securities in one or more series. Debt securities will be issued under the indenture dated as of November 17, 2006, as supplemented by the supplemental indenture dated as of September 6, 2007 and the supplemental indenture dated as of May 3, 2019, between us and Computershare Trust Company, N.A., as successor to Wells Fargo Bank, National Association, as trustee, or any other indenture which we identify in a prospectus supplement (we refer to the November 17, 2006 indenture or any such other indenture, in each case as supplemented from time to time, as the “indenture”). We have summarized below the material provisions of the indenture. However, because this summary is not complete, it is subject to and is qualified in its entirety by reference to the indenture. The trustee assumes no responsibility and will have no liability for the accuracy, correctness, adequacy, or completeness of the information concerning us or our affiliates or any other party contained in this prospectus 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, accuracy, correctness, adequacy or completeness of such information. The trustee is entitled to those certain rights, powers, privileges, protections, indemnities, limitations of liability, and immunities as more fully set forth in the indenture. In this “Description of Debt Securities,” “we,” “us,” “our” and similar words refer to The Western Union Company and not any of its Subsidiaries (as defined below under “—Certain Definitions”).

General

The debt securities will be our unsecured obligations and rank on a parity with our other unsecured and unsubordinated indebtedness.

We conduct our operations through our Subsidiaries. Our rights and the rights of our creditors, including the holders of the debt securities, to participate in the distribution of assets of any of our Subsidiaries upon the liquidation or reorganization of that Subsidiary or otherwise, will be subject to the prior claims of the Subsidiary’s creditors, except to the extent that we may be a creditor with recognized claims against the Subsidiary or such Subsidiary guarantees the debt securities. As a result, the debt securities will be effectively subordinated to existing and future liabilities of our Subsidiaries.

We may issue the debt securities in one or more series, as authorized from time to time by our board of directors, any committee of our board of directors or any duly authorized officer. The indenture does not limit our ability to incur additional indebtedness, nor does it afford holders of the debt securities protection in the event of a highly leveraged or similar transaction involving our company. However, the indenture provides that neither we nor any Restricted Subsidiary may subject certain of our property or assets to any mortgage or other encumbrance unless the debt securities are secured equally and ratably with or prior to that other secured indebtedness. See “—Certain Covenants” below. Reference is made to the applicable prospectus supplement for information with respect to any additions to, or modifications or deletions of, the events of default or covenants described below.

We will describe in a supplement to this prospectus the particular terms of any debt securities being offered, any modifications of or additions to the general terms of the debt securities and any U.S. Federal income tax considerations that may be applicable in the case of offered debt securities. Accordingly, you should read both the prospectus supplement relating to the particular debt securities being offered and the general description of debt securities set forth in this prospectus before investing.

The applicable prospectus supplement will describe specific terms relating to the series of debt securities being offered. These terms will include some or all of the following:

•

the title of the series of debt securities;

•

the aggregate principal amount and authorized denominations (if other than $1,000 and integral multiples of $1,000);

•

the initial public offering price;

•

the original issue and stated maturity date or dates;

•

the interest rate or rates (which may be fixed or floating), if any, the method by which the rate or rates will be determined and the interest payment and regular record dates;

•

the manner and place of payment of principal and interest, if any;

•

if other than U.S. dollars, the currency or currencies in which payment of the initial public offering price and/or principal and interest, if any, may be made;

•

whether (and if so, when and at what price) we may be obligated to repurchase the debt securities;

•

whether (and if so, when and at what price) the debt securities can be redeemed by us or the holder;

•

under what circumstances, if any, we will pay additional amounts on the debt securities to non-U.S. holders in respect of taxes;

•

whether the debt securities will be issued in registered or bearer form (with or without coupons) and, if issued in the form of one or more global securities, the depositary for such securities;

•

where the debt securities can be exchanged or transferred;

•

whether the debt securities may be issued as original issue discount securities, and if so, the amount of discount and the portion of the principal amount payable upon declaration of acceleration of the maturity thereof;

•

whether (and if so, when and at what rate) the debt securities will be convertible into shares of our common stock;

•

whether there will be a sinking fund;

•

provisions, if any, for the defeasance of the debt securities;

•

any addition to, or modification or deletion of, any events of default or covenants contained in the indenture relating to the debt securities; and

•

any other terms of the series.

If we issue original issue discount securities, we will also describe in the applicable prospectus supplement the U.S. Federal income tax consequences and other special considerations applicable to those securities.

We are not required to issue all of the debt securities of a series at the same time, and debt securities of the same series may vary as to interest rate, maturity and other provisions. Unless otherwise provided, the aggregate principal amount of a series may be increased and additional debt securities of such series may be issued.

Denominations, Exchange, Registration and Transfer

Unless otherwise specified in the applicable prospectus supplement, the debt securities of any series will be issued only as registered securities, in global or certificated form and in denominations of $1,000 and any integral multiple thereof, and will be payable only in U.S. dollars. Unless otherwise indicated in the applicable prospectus supplement, any debt securities we issue in bearer form will have coupons attached.

Registered debt securities of any series will be exchangeable for other registered debt securities of the same series in the same aggregate principal amount and having the same stated maturity date and other terms and conditions. If so provided in the applicable prospectus supplement, to the extent permitted by law, debt securities of any series issued in bearer form which by their terms are registrable as to principal and interest may be exchanged,

at the option of the holders, for registered debt securities of the same series in the same aggregate principal amount and having the same stated maturity date and other terms and conditions, upon surrender of those

securities at the corporate trust office of the trustee or at any other office or agency designated by us for the purpose of making any such exchanges. Except in certain limited circumstances, debt securities issued in bearer form with coupons surrendered for exchange must be surrendered with all unmatured coupons and any matured coupons in default attached thereto.

Upon surrender for registration of transfer of any registered debt security of any series at the office or agency maintained for that purpose, we will execute, and the trustee will authenticate and deliver, in the name of the designated transferee, one or more new registered debt securities of the same series in the same aggregate principal amount of authorized denominations and having the same stated maturity date and other terms and conditions. We may not impose any service charge, other than any required tax or other governmental charge, on the transfer or exchange of debt securities.

We are not required (i) to issue, register the transfer of or exchange debt securities of any series during the period from the opening of business 15 days before the day a notice of redemption relating to debt securities of that series selected for redemption is sent to the close of business on the day that notice is sent, or (ii) to register the transfer of or exchange any debt security so selected for redemption, except for the unredeemed portion of any debt security being redeemed in part.

Payment and Paying Agents

We will maintain in each place of payment for those debt securities an office or agency where the debt securities may be presented or surrendered for payment or for registration of transfer or exchange and where holders may serve us with notices and demands in respect of the debt securities and the indenture.

We will give prompt written notice to the trustee of the location, and any change in the location, of such office or agency. If we fail to maintain any required office or agency or fail to furnish the trustee with the address of such office or agency, presentations, surrenders, notices and demands may be made or served at the corporate trust office of the trustee. We have appointed the trustee as our agent to receive all presentations, surrenders, notices and demands with respect to the applicable series of debt securities.

Certain Covenants

Unless otherwise specified in the applicable prospectus supplement, the following covenants apply to the debt securities:

Limitation on Mortgages and Liens. Neither we nor any of our Restricted Subsidiaries may create or assume, except in favor of us or one of our wholly owned Subsidiaries, any Lien upon any Principal Facility (as defined below under “—Certain Definitions”) without equally and ratably securing any debt securities then outstanding. However, this limitation does not apply to certain permitted Liens as described in the indenture, including:

•

purchase money mortgages entered into within specified time limits, and Liens extending, renewing or refunding those purchase money mortgages;

•

Liens on acquired property existing at the time of the acquisition;

•

certain tax, materialmen’s, mechanics’ and judgment Liens, Liens arising by operation of law and other similar Liens;

•

Liens in connection with certain government contracts;

•

certain Liens in favor of any state or local government or governmental agency in connection with certain tax-exempt financings;

•

Liens in connection with workers’ compensation, unemployment insurance, other social security benefits or other insurance related obligations and Liens on the proceeds of the foregoing;

•

deposits to secure the performance of bids, certain trade contracts, leases, statutory obligations, surety and appeal bonds, performance bonds, judgment and like bonds and similar bonds and other obligations of like nature incurred in the ordinary course of business;

•

zoning restrictions, easements, rights-of-way and similar encumbrances incurred in the ordinary course of business and minor irregularities of title, which do not materially interfere with the ordinary conduct of our business or our Subsidiaries taken as a whole;

•

Liens on Purchased Receivables and related assets granted in connection with one or more Purchased Receivables Financing;

•

Liens to secure the cost of construction or improvement of any property entered into within specified time limits; and

•

Liens not otherwise permitted if the sum of the indebtedness secured by those Liens plus the aggregate sales price of property involved in sale and leaseback transactions referred to in the first bullet point under “—Limitation on Sale and Leaseback Transactions” below, does not exceed the greater of $300 million or 15% of our Consolidated Net Worth (as defined below under “—Certain Definitions”).

Limitation on Sale and Leaseback Transactions. Neither we nor any of our Subsidiaries may sell any Principal Facility owned on the date of the indenture with the intention of taking back a lease of that facility for a period of more than 36 months other than certain computer hardware leases, unless:

•

the sum of the aggregate sale price of property involved in sale and leaseback transactions not otherwise permitted plus the aggregate amount of indebtedness secured by Liens referred to in the last bullet point above under “—Limitation on Mortgages and Liens” does not exceed the greater of $300 million or 15% of our Consolidated Net Worth;

•

the sale and leaseback transaction is entered into between us and one or more of our Subsidiaries or between our Subsidiaries; or

•

the net proceeds of the sale or the fair market value of the Principal Facility, whichever is greater (which may be conclusively determined by our board of directors, any authorized committee thereof or any of our duly authorized officers), are applied within 120 days to the optional retirement of debt securities then outstanding or to the optional retirement of our other Funded Debt (as defined below under “—Certain Definitions”) ranking on a parity with the debt securities; provided, that the amount required to be applied to the retirement of outstanding debt securities or our Funded Debt pursuant to this bullet point shall be reduced by the principal amount of any debt securities or of our Funded Debt voluntarily retired by us within 120 days after such sale, whether or not any such retirement of the debt securities or Funded Debt shall be specified as being made pursuant to this bullet point.

Covenant to File Reports. We will file with the trustee, within 15 days after we have filed with the SEC, copies of the annual reports and of the information, documents, and other reports which we have so filed with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act.

Merger or Consolidation

We may not consolidate with or merge into any other entity or sell, lease, convey, assign, transfer or otherwise dispose of our properties and assets substantially as an entirety or as an entirety to any person, unless:

•

we are the survivor formed by or resulting from such consolidation or merger;

•

the surviving or successor entity is a domestic entity and expressly assumes, by supplemental indenture, all of our obligations under the indenture;

•

immediately after completion of the transaction, no Event of Default, and no event which, after notice or lapse of time, or both, would become an Event of Default, has occurred and is continuing;

•

if, as a result of the transaction, our properties or assets would become subject to a Lien covered by the provisions described above under “—Certain Covenants—Limitation on Mortgages and Liens,” and none of the exceptions therein apply, we or the surviving or successor entity takes such steps as are necessary to effectively secure all debt securities equally and ratably with (or prior to) all indebtedness secured by such Lien; and

•

we deliver to the trustee an officers’ certificate and an opinion of counsel each stating that the transaction and any supplemental indenture comply with the indenture provisions and that all conditions precedent in the indenture relating to such transaction have been complied with.

For purposes of this covenant, the sale, lease, conveyance, assignment, transfer, or other disposition of the properties and assets substantially as an entirety or as an entirety of one or more of our Subsidiaries, which properties and assets, if held by us instead of such Subsidiary or Subsidiaries, would constitute our properties and assets substantially as an entirety or as an entirety on a consolidated basis, shall be deemed to be the transfer of our properties and assets substantially as an entirety or as an entirety.

Events of Default

“Event of Default” means, with respect to a series of debt securities, any of the following events:

•

failure to pay interest on the debt securities of such series, which failure continues for a period of 30 days after payment is due;

•

failure to make any principal or premium payment on the debt securities of such series when due;

•

failure to perform or comply with any other covenant or warranty in the indenture with respect to the debt securities of such series for a period of 90 days after notice to us of such failure by (i) the trustee or (ii) the holders of at least 25% in principal amount of the outstanding debt securities of such series;

•

default under any Indebtedness of us or our Restricted Subsidiaries in an aggregate principal amount of $100 million or more and which default (i) constitutes a failure to make any scheduled principal or interest payment when due after giving effect to any applicable grace period or (ii) accelerates the payment of such debt and such acceleration is not rescinded or annulled, or such debt is not discharged, within 15 days after notice to us of such default by (i) the trustee or (ii) the holders of at least 25% in principal amount of the outstanding debt securities of such series;

•

the entry against us or our Restricted Subsidiaries of one or more final judgments, decrees or orders by a court for the payment of money aggregating in excess of $100 million, which judgment, decree or order is not paid, discharged or stayed for any period of 45 consecutive days or, in the case of a foreign judgment not being sought in the United States, 60 consecutive days, after the amount thereof is due; provided, however, that such amount is calculated after deducting certain insurance coverage;

•

certain events of bankruptcy, insolvency or reorganization of our company; and

•

any other event of default provided with respect to debt securities of such series pursuant to the indenture.

In general, the trustee is required to give notice of a default actually known to a responsible officer of the trustee with respect to a series of debt securities to the holders of debt securities of such series within 90 days after it occurs and a responsible officer of the trustee has received actual knowledge of such default. However, the trustee may withhold notice of any default (except a default in payment of principal or interest on any debt security of such series) if the trustee determines it is in the interest of the holders of debt securities of such series to do so.

Our failure to comply with Section 314(a) of the Trust Indenture Act of 1939, as amended (relating to the filing of reports, information and other documents with the SEC), shall not constitute a Default or an Event of Default with respect to any series of debt securities.

If there is a continuing Event of Default with respect to a series of debt securities, then the trustee or the holders of at least 25% in principal amount of the debt securities of such series may require us to repay the principal amount on the debt securities of such series immediately. Upon payment of the principal or other specified amount, our obligations in respect of the payment of principal of the debt securities of such series will terminate.

Subject to the provisions of the indenture relating to the rights, protections, and duties of the trustee, in the case of a continuing Event of Default with respect to a series of debt securities, the trustee may refuse to exercise any of its rights or powers under the indenture with respect to such series of debt securities at the request, order or direction of any of the holders of debt securities of such series unless it first receives reasonable indemnity and/or security against the costs, expenses and liabilities which might be incurred by it in compliance with such request, order or direction. Subject to this limitation, the holders of a majority in principal amount of the outstanding debt securities of the affected series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee under the indenture with respect to such series of debt securities or exercising any trust or power conferred on the trustee with respect to the debt securities of such series.

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

•

we have paid or deposited with the trustee a sum sufficient to pay (i) all overdue installments of interest or other payments with respect to coupons on all the debt securities of such series, (ii) the principal of, premium, if any, and interest on any debt securities of such series which have become due otherwise than by such declaration of acceleration, (iii) to the extent that such payment is lawful, interest on overdue installments of interest or other payments with respect to coupons on each debt security of such series at a rate established for such series, and (iv) all sums paid or advanced by the trustee and the reasonable compensation, expenses, disbursements and advances of the trustee, its agents and counsel; and

•

all events of default with respect to the debt securities of such series, other than the nonpayment of principal which has become due solely by such declaration of acceleration, have been cured or waived as provided in the indenture.

No such rescission and annulment will affect any subsequent default or impair any right consequent thereon.

We are required to provide the trustee with an officers’ certificate each fiscal year stating whether or not we have complied with all conditions and covenants under the indenture.

Modification or Waiver

We and the trustee may, at any time and from time to time, amend the indenture without the consent of the holders of outstanding debt securities for any of the following purposes:

•

to effect the assumption of our obligations under the indenture by a successor corporation;

•

to impose additional covenants and events of default for the benefit of the holders of any series of debt securities;

•

to add or change any of the provisions of the indenture relating to the issuance or exchange of debt securities of any series in registered form, but only if such action does not adversely affect the interests of the holders of outstanding debt securities of such series or related coupons in any material respect;

•

to change or eliminate any of the provisions of the indenture, but only if the change or elimination becomes effective when there is no outstanding debt security of any series or related coupon which is entitled to the benefit of such provision and as to which such modification would apply;

•

to secure the debt securities;

•

to supplement any of the provisions of the indenture to permit or facilitate the defeasance and discharge of any series of debt securities, but only if such action does not adversely affect the interests of the holders of outstanding debt securities of any series or related coupons in any material respect;

•

to establish the form or terms of the debt securities and coupons, if any, of any series as permitted by the indenture;

•

to evidence and provide for the acceptance of appointment by a successor trustee and to add to or change any of the provisions of the indenture to facilitate the administration of the trusts by more than one trustee; and

•

to correct any mistakes or defects in the indenture, but only if such action does not adversely affect the interests of the holders of outstanding debt securities of any series or related coupons in any material respect or to otherwise amend the indenture in any respect that does not adversely affect the holders of outstanding debt securities.

In addition, we and the trustee may modify the indenture and the debt securities of any series with the consent of the holders of not less than a majority in principal amount of each series of outstanding debt securities affected by such modification to add, change or eliminate any provision of, or to modify the rights of holders of debt securities of such series under, the indenture. But we may not take any of the following actions without the consent of each holder of outstanding debt securities affected thereby:

•

change the stated maturity of the principal of, or any installment of interest on, the debt securities of any series or related coupon, reduce the principal amount thereof, the interest thereon or any premium payable upon redemption thereof, or change the currency or currencies in which the principal, premium or interest is denominated or payable;

•

reduce the amount of, or impair the right to institute suit for the enforcement of, any payment on the debt securities of any series following maturity thereof;

•

reduce the percentage in principal amount of outstanding debt securities of any series required for consent to any waiver of defaults or compliance with certain provisions of the indenture; or

•

modify any provision of the indenture relating to modifications and waivers of defaults and covenants, except to increase any such percentage or to provide that certain other provisions cannot be modified or waived without the consent of each holder of outstanding debt securities affected thereby.

A modification with respect to one or more particular series of debt securities and related coupons, if any, will not affect the rights under the indenture of the holders of debt securities of any other series and related coupons, if any.

The holders of a majority in principal amount of the outstanding debt securities of all series affected may, on behalf of the holders of all debt securities of such series, waive any past default under the indenture with respect to the debt securities of such series, except a default (i) in the payment of principal of, premium, if any, or interest on such series or (ii) in respect of a covenant or provision which, as described above, cannot be modified or amended without the consent of each holder of debt securities of such series. Upon any such waiver, the

default will cease to exist with respect to the debt securities of such series and any Event of Default arising therefrom will be deemed to have been cured for every purpose of the debt securities of such series under the indenture, but the waiver will not extend to any subsequent or other default or impair any right consequent thereon. We may elect in any particular instance not to comply with certain covenants set forth in the indenture or the debt securities of any series (except as otherwise provided in the covenants described above under “—Certain Covenants”) if, before the time for such compliance, the holders of at least a majority in principal amount of the outstanding debt securities of such series either waive compliance in that instance or generally waive compliance with those provisions, but the waiver may not extend to or affect any term, provision or condition except to the extent expressly so waived, and, until the waiver becomes effective, our obligations and the duties of the trustee in respect of any such provision will remain in full force and effect.

Discharge, Legal Defeasance and Covenant Defeasance

We may be discharged from all of our obligations with respect to the outstanding debt securities of any series (except as otherwise provided in the indenture) when:

•

either (i) all the debt securities of such series and related coupons, if any, have been delivered to the trustee for cancellation, or (ii) all the debt securities of such series and related coupons, if any, not delivered to the trustee for cancellation:

•

have become due and payable;

•

will become due and payable at their stated maturity within one year; or

•

are to be called for redemption within one year under arrangements satisfactory to the trustee for the giving of notice by the trustee; and we, in the case of clause (ii), have irrevocably deposited or caused to be deposited with the trustee, in trust, an amount in U.S. dollars sufficient for payment of all principal of, premium, if any, and interest on those debt securities when due or to the date of deposit, as the case may be; provided, however, in the event a petition for relief under any applicable federal or state bankruptcy, insolvency or other similar law is filed with respect to our company within 91 days after the deposit and the trustee is required to return the deposited money to us, our obligations under the indenture with respect to those debt securities will not be deemed terminated or discharged;

•

we have paid or caused to be paid all other sums payable by us under the indenture;

•

we have delivered to the trustee an officers’ certificate and an opinion of counsel each stating that all conditions precedent relating to the satisfaction and discharge of the indenture with respect to such series of debt securities have been complied with; and

•

we have delivered to the trustee an opinion of counsel of recognized standing in respect of U.S. federal income tax matters or a ruling of the Internal Revenue Service to the effect that holders of debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit and discharge.

We may elect (i) to be discharged from our obligations with respect to the outstanding debt securities of any series (except as otherwise specified in the indenture) or (ii) to be released from our obligation to comply with the provisions of the indenture described above under “—Certain Covenants” and under “—Merger or Consolidation” with respect to the outstanding debt securities of any series (and, if so specified, any other obligation or restrictive covenant added for the benefit of the holders of such series of debt securities), in either case, if we satisfy each of the following conditions:

•

we deposit or cause to be deposited irrevocably with the trustee, in trust, specifically pledged as security for, and dedicated solely to, the benefit of the holders of debt securities of such series money or the equivalent in U.S. government securities, or any combination thereof, sufficient, in the opinion

of a nationally recognized firm of independent public accountants expressed in a written certification delivered to the trustee, for payment of all principal of, premium, if any, and interest on the outstanding debt securities of such series when due;

•

such deposit does not cause the trustee with respect to the debt securities of such series to have a conflicting interest with respect to the debt securities of such series;

•

such deposit will not result in a breach or violation of, or constitute a default under, the indenture or any other agreement or instrument to which we are a party or by which we are bound;

•

on the date of such deposit, there is no continuing Event of Default with respect to the debt securities of such series or event (including such deposit) which, with notice or lapse of time or both, would become an Event of Default with respect to the debt securities of such series and, with respect to the option under clause (i) above only, no Event of Default with respect to such series under the provisions of the indenture relating to certain events of bankruptcy or insolvency or event which, with notice or lapse of time or both, would become an Event of Default with respect to such series under such bankruptcy or insolvency provisions shall have occurred and be continuing on the 91st day after such date; and

•

we deliver to the trustee an opinion of counsel of recognized standing in respect of U.S. federal income tax matters or a ruling of the Internal Revenue Service to the effect that the holders of debt securities of such series will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such deposit, defeasance or discharge.

Notwithstanding the foregoing, if we exercise our option under clause (ii) above and an Event of Default with respect to such series of debt securities under the provisions of the indenture relating to certain events of bankruptcy or insolvency or event which, with notice or lapse of time or both, would become an Event of Default with respect to such series of debt securities under such bankruptcy or insolvency provisions shall have occurred and be continuing on the 91st day after the date of such deposit, our obligation to comply with the provisions of the indenture described above under “—Certain Covenants” and under “—Merger or Consolidation” with respect to those debt securities will be reinstated.

These terms will include the conversion price, the conversion period, provisions as to whether conversion will be at our option or the option of the holder, events requiring an adjustment of the conversion price and provisions affecting conversion in the event of the redemption of the debt securities.

PLAN OF DISTRIBUTION

We may sell debt securities offered by this prospectus in and/or outside the United States:

•

through underwriters or dealers;

•

through agents; or

•

directly to purchasers.

We will describe in a prospectus supplement the particular terms of any offering of debt securities, including the following:

•

the names of any underwriters or agents;

•

the proceeds we will receive from the sale;

•

any discounts and other items constituting underwriters’ or agents’ compensation;

•

any discounts or concessions allowed or reallowed or paid to dealers; and

•

any securities exchanges on which the applicable debt securities may be listed.

If we use underwriters in the sale, such underwriters will acquire the debt securities for their own account. The underwriters may resell the debt securities in one or more transactions, at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to prevailing market prices or at negotiated prices.

The debt securities may be offered to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. The obligations of the underwriters to purchase the debt securities will be subject to certain conditions. The underwriters will be obligated to purchase all the debt securities of the series offered if any of the debt securities are purchased.

We may sell debt securities through agents or dealers designated by us. Any agent or dealer involved in the offer or sale of the debt securities for which this prospectus is delivered will be named, and any commissions payable by us to that agent or dealer will be set forth, in the prospectus supplement. Unless indicated in the prospectus supplement, the agents will agree to use their reasonable efforts to solicit purchases for the period of their appointment and any dealer will purchase debt securities from us as principal and may resell those debt securities at varying prices to be determined by the dealer.

We also may sell debt securities directly. In this case, no underwriters or agents would be involved.

Underwriters, dealers and agents that participate in the distribution of the debt securities may be underwriters as defined in the Securities Act, and any discounts or commissions received by them from us and any profit on the resale of the debt securities by them may be treated as underwriting discounts and commissions under the Securities Act.

We may have agreements with the underwriters, dealers and agents to indemnify them against certain civil liabilities, including liabilities under the Securities Act or to contribute with respect to payments which the underwriters, dealers or agents may be required to make.

Underwriters, dealers and agents may engage in transactions with, or perform services for, us or our subsidiaries in the ordinary course of their businesses.

In order to facilitate the offering of the debt securities, any underwriters or agents, as the case may be, involved in the offering of such securities may engage in transactions that stabilize, maintain or otherwise affect

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

We may solicit offers to purchase debt securities directly from, and we may sell debt securities directly to, institutional investors or others. The terms of any of those sales, including the terms of any bidding or auction process, if utilized, will be described in the applicable prospectus supplement.

Some or all of the debt securities may be new issues of securities with no established trading market. We cannot and will not give any assurances as to the liquidity of the trading market for any of our securities.

LEGAL MATTERS

The validity of the debt securities and certain other matters will be passed upon for us by Sidley Austin LLP, Chicago, Illinois.

EXPERTS

The consolidated financial statements of The Western Union Company appearing in The Western Union Company’s Annual Report (Form 10-K) for the year ended December 31, 2024, and the effectiveness of The Western Union Company’s internal control over financial reporting as of December 31, 2024 have been audited by Ernst & Young LLP, independent registered public accounting firm, as set forth in their reports thereon, included therein, and incorporated herein by reference. Such consolidated financial statements are incorporated herein by reference in reliance upon such reports given on the authority of such firm as experts in accounting and auditing.

With respect to the unaudited condensed consolidated interim financial information of The Western Union Company for the three-month periods ended March 31, 2025 and 2024 and the three-month and six-month periods ended June 30, 2025 and 2024, incorporated by reference in this prospectus, Ernst & Young LLP reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate reports dated April 23, 2025 and July 28, 2025, included in The Western Union Company’s Quarterly Reports on Form 10-Q for the quarters ended March 31, 2025 and June 30, 2025, respectively, and incorporated by reference herein, state that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their reports on such information should be restricted in light of the limited nature of the review procedures applied. Ernst & Young LLP is not subject to the liability provisions of Section 11 of the Securities Act for their report on the unaudited interim financial information because that report is not a “report” or a “part” of the registration statement prepared or certified by Ernst & Young LLP within the meaning of Sections 7 and 11 of the Securities Act.
