**FORWARD-LOOKING STATEMENTS AND CAUTIONARY FACTORS**

We have included or may include statements in this prospectus supplement and the accompanying prospectus (including documents incorporated by reference) that constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended ("Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended ("Exchange Act"). Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, goals, strategies, assumptions or future events or performance may be forward-looking statements. Also, forward-looking statements may be identified by reference to a future period or periods or by the use of forward-looking terminology such as "anticipates," "believes," "could," "estimates," "expects," "forecasts," "goals," "guidance," "intends," "may," "objectives," "plans," "possible," "potential," "projects," "seeks," "should," "targets," "will" or similar terms or variations of these terms.

**We caution you that any forward-looking statements are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to differ materially from the future results, performance or achievements we have anticipated in the forward-looking statements.**

In addition to the assumptions and other factors referred to specifically in connection with those statements, factors that could cause our actual results, performance or achievements to differ materially from those contemplated in the forward-looking statements include factors we have described under the captions "Cautionary Statement Regarding Forward-Looking Information" and "Risk Factors" in [our Annual Report on Form 10-K for the year ended December 31, 2024](https://www.sec.gov/ix?doc=/Archives/edgar/data/107833/000010781525000107/wps-20241231.htm), and under the caption "Factors Affecting Results, Liquidity, and Capital Resources" in the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section of our [Annual Report on Form 10-K for the year ended December 31, 2024](https://www.sec.gov/ix?doc=/Archives/edgar/data/107833/000010781525000107/wps-20241231.htm), or under similar captions in the other documents we have incorporated by reference. Any forward-looking statement speaks only as of the date on which that statement is made, and, except as required by applicable law, we do not undertake any obligation to update any forward-looking statement to reflect events or circumstances, including unanticipated events, after the date on which that statement is made.

**USE OF PROCEEDS**

We estimate the net proceeds to us from the offering to be approximately $ million, after deducting the underwriting discounts and estimated offering expenses payable by us. We intend to use the net proceeds from the offering to repay short-term debt and for other general corporate purposes. At December 29, 2025, our outstanding short-term debt of $164.5 million had a weighted average interest rate of 3.92% and an average life of less than 30 days.

Pending disposition, we may temporarily invest the net proceeds of the offering not required immediately for the intended purposes in U.S. governmental securities and other high quality U.S. securities.

**CERTAIN TERMS OF THE NOTES**

The following description of the particular terms of the Notes supplements and, to the extent inconsistent therewith, replaces the description of the general terms and provisions of the Notes set forth in the accompanying prospectus under "Description of the Senior Debt Securities."

We will issue the Notes under a Trust Indenture dated as of December 1, 1998 between us and U.S. Bank Trust Company, National Association (successor to Firstar Bank Milwaukee, N.A., National Association), as trustee, as supplemented and amended by any supplemental indentures, which we refer to collectively in this prospectus supplement as the "senior indenture." The Notes will be our direct unsecured general obligations. As of September 30, 2025, the aggregate principal amount of debt securities outstanding under the senior indenture was approximately $2.3 billion.

**General**

The Notes will be unsecured and unsubordinated and will rank equally with all of our other unsecured and unsubordinated indebtedness and other obligations from time to time outstanding. As of September 30, 2025, we had approximately $2.3 billion aggregate principal amount of unsecured long-term debt securities and commercial paper outstanding.

Interest on the Notes will accrue at the rate of % per year. Interest will accrue from January , 2026, or from the most recent interest payment date to which interest has been paid or provided for. Interest is payable semi-annually in arrears to holders of record at the close of business on the or (whether or not such day is a business day) immediately preceding the interest payment date. Interest payment dates will be and of each year beginning on , 2026. If any interest payment date, redemption date or the maturity date should fall on a day that is not a business day, any payment of interest or principal will be made on the next succeeding business day and no additional interest will accrue as a result of such delayed payment. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Notes will mature on , 20 .

The Notes will be issued only in registered form in denominations of $1,000 and multiples thereof.

**Redemption at Our Option**

Prior to , 20 (the date that is month(s) prior to the maturity date, which is referred to in this prospectus supplement as the "Par Call Date"), we may redeem the Notes at our option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus basis points less (b) interest accrued to, but not including, the date of redemption; and

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

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

On or after the Par Call Date, we may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest thereon to, but not including, the redemption date.

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

The Treasury Rate shall be determined by us after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted each business day 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, we 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, we shall calculate the Treasury Rate based on the rate per annum equal to the semiannual 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, we 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, we shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semiannual 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.

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

We will send notice at least 10 days, but not more than 45 days, before the redemption date to each holder of Notes to be redeemed.

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

Unless we have deposited with the Trustee, at the time of sending of any notice of redemption, an amount in cash sufficient to redeem all of the Notes called for redemption, the notice will state that it is subject to the receipt of the redemption moneys by the Trustee before the redemption date, and the notice will be of no effect unless the moneys are so received, before that date.

The Notes have no sinking fund provisions.

**Covenants**

The senior indenture contains covenants that, among other things, limit our ability to incur certain additional liens or engage in certain sale-leaseback transactions. These covenants are subject to termination upon defeasance and to certain significant exceptions described under "Description of the Senior Debt Securities – Limitation on Liens" and "– Limitations on Sale and Lease-Back Transactions" in the accompanying prospectus. Future series of securities issued under the senior indenture may or may not have different covenants.

The senior indenture provides that, in addition to the Notes being offered hereby, other senior debt securities may be issued from time to time, in one or more series, under the senior indenture, without limitation as to aggregate principal amount. In addition, there is no requirement under the senior indenture that future issues of our debt securities be issued under the senior indenture.

**Other**

The Notes will be subject to defeasance under the conditions described in the accompanying prospectus.

We may from time to time without notice to, or the consent of, the holders of the Notes, issue additional notes under the senior indenture having the same terms in all respects, except for the issue date, the public offering price and, if applicable, the initial interest payment date. Any such additional notes will be consolidated with and form a single series with the Notes for all purposes, including, without limitation, waivers, amendments, redemptions and offers to purchase. In the event we issue additional notes of the same series, we will prepare a new offering memorandum or prospectus.

The senior indenture and the Notes will be governed by, and construed under, the laws of the State of Wisconsin.

**Book-Entry Only Issuance—The Depository Trust Company**

The Depository Trust Company ("DTC"), New York, NY, will act as the securities depository for the Notes. The Notes will be issued only as fully-registered securities registered in the name of Cede & Co. (DTC's partnership nominee) or such other name as may be requested by an authorized representative of DTC. We will issue one or more fully-registered global note certificates, representing in the aggregate the total principal amount of the Notes, and will deposit each such certificate with the Trustee on behalf of DTC.

DTC, the world's largest securities depository, is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues and money market instruments from over 100 countries that DTC's participants ("Direct Participants") deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants' accounts. This eliminates 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 certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. 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 ("Indirect Participants"). The DTC Rules applicable to its Participants are on file with the SEC. More information about DTC can be found at www.dtcc.com. The contents of such website do not constitute part of this prospectus supplement or the accompanying prospectus.

Purchases of the Notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the Notes on DTC's records. The ownership interest of each actual purchaser of each Note ("Beneficial Owner") is in turn to be recorded on the Direct and Indirect Participants' records. Beneficial Owners will not receive written confirmation from DTC of their purchases. Beneficial Owners, however, are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the Direct or Indirect Participants through which the Beneficial Owners purchased Notes. Transfers of ownership interests in the Notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the Notes, except in the event that use of the book-entry system for the Notes is discontinued.

To facilitate subsequent transfers, all Notes deposited by Direct Participants with DTC are registered in the name of DTC's partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of the Notes with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any changes in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Notes. DTC's records reflect only the identity of the Direct Participants to whose accounts such Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

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 the Notes are being redeemed, DTC's practice is to determine by lot the amount of the interest of each Direct Participant in such Notes to be redeemed.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the Notes unless authorized by a Direct Participant in accordance with DTC's procedures. Under its usual procedures, DTC mails an Omnibus Proxy to us 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 the Notes are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Payments on the Notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC's practice is to credit Direct Participants' accounts upon DTC's receipt of funds and corresponding detail information from us or the Trustee on the relevant payment date in accordance with their respective holdings shown on DTC's records. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers registered in "street name," and will be the responsibility of such Participant and not of DTC or Wisconsin Public Service, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of Wisconsin Public Service, disbursement of such payments to Direct Participants is the responsibility of DTC, and disbursement of such payments to the Beneficial Owners is the responsibility of Direct and Indirect Participants.

Except as provided herein, a Beneficial Owner of a global Note will not be entitled to receive physical delivery of a Note. Accordingly, each Beneficial Owner must rely on the procedures of DTC to exercise any rights under the Notes. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global Note.

DTC may discontinue providing its services as securities depository with respect to the Notes at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor securities depository is not obtained, Note certificates will be required to be printed and delivered to the holders of record. Additionally, we may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository) with respect to the Notes. We understand, however, that under current industry practices, DTC would notify its Direct and Indirect Participants of our decision, but will only withdraw beneficial interests from a global Note at the request of each Direct or Indirect Participant. In that event, certificates for the Notes will be printed and delivered to the applicable Direct or Indirect Participant.

The information in this section concerning DTC and DTC's book-entry system has been obtained from sources that we believe to be reliable, but neither we nor any underwriter takes any responsibility for the accuracy thereof. Neither we nor any underwriter has any responsibility for the performance by DTC or its Direct or Indirect Participants of their respective obligations as described herein or under the rules and procedures governing their respective operations.

**Underwriting (Conflicts of Interest)**

Subject to the terms and conditions contained in an underwriting agreement dated the date of this prospectus supplement, the underwriters named below, for whom MUFG Securities Americas Inc., PNC Capital Markets LLC and Scotia Capital (USA) Inc. are acting as representatives, have severally agreed to purchase, and we have agreed to sell to them, severally, the principal amount of Notes indicated in the following table:

---

| | |
|:---|:---|
| <br>**Underwriter** | **Principal Amount**<br>**of Notes** |
| MUFG Securities Americas Inc. | $— |
| PNC Capital Markets LLC |  |
| Scotia Capital (USA) Inc. |  |
| Cabrera Capital Markets LLC |  |
| &nbsp;&nbsp;&nbsp;Total | $— |

---

The underwriters are offering the Notes subject to their acceptance of the Notes from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the Notes offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the Notes offered by this prospectus supplement if any are taken.

Notes sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover page of this prospectus supplement. Any Notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to % of the principal amount of the Notes. Any such securities dealers may resell any Notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price of up to % of the principal amount of the Notes. After the initial public offering of the Notes, the offering price and other selling terms may from time to time be varied by the representatives. The offering of the Notes by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

The following table shows the underwriting discounts that we are to pay to the underwriters in connection with this offering (expressed as a percentage of the principal amount of the Notes).

Per Note%

In order to facilitate the offering of the Notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Notes. Specifically, the underwriters may over-allot in connection with the offering, creating a short position in the Notes for their own account. In addition, to cover over-allotments or to stabilize the price of the Notes, the underwriters may bid for, and purchase, Notes on the open market. Short sales involve the sale by the underwriters of a greater number of Notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the Notes while the offering is in progress. Finally, the underwriters may reclaim selling concessions allowed to an underwriter or a dealer for distributing the Notes in the offering, if the underwriters repurchase previously distributed Notes 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 Notes above independent market levels. The underwriters are not required to engage in these activities and may end any of these activities at any time. These transactions may be effected in the over-the-counter market or otherwise.

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

The Notes are a new issue of debt securities with no established trading market. We have been advised by the underwriters that they intend to make a market in the Notes, but they are not obligated to do so and may discontinue market making at any time without notice. We cannot assure you as to the liquidity of the trading market for the Notes.

We estimate that our total expenses for this offering, not including the underwriting discount, will be approximately $1.0 million.

We expect to deliver the Notes against payment for the Notes on or about the date specified in the last paragraph on the cover page of this prospectus supplement, which will be the business day following the date of the pricing of the Notes (this settlement cycle being referred to as "T+ "). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in one business day, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Notes on the date of pricing or the next succeeding business day(s) will be required, by virtue of the fact that the Notes initially will settle in T+ , to specify alternate settlement arrangements to prevent a failed settlement. Purchasers of Notes who wish to trade Notes on the date of pricing or the next succeeding business day(s) should consult their own advisors.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, hedging, financing and brokerage activities. In the ordinary course of their respective businesses, certain of the underwriters and their affiliates have provided, currently provide, and may in the future provide, investment banking, commercial banking, advisory and other services for us and our affiliates, for which they received and will receive customary fees and expenses. Affiliates of each of the book running managers are lenders under our existing $450 million revolving credit facility.

In the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments, including serving as counterparties to certain derivative hedging arrangements, 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 investment and securities activities may involve securities and instruments of Wisconsin Public Service and its affiliates. Certain of the underwriters or their respective affiliates that have a lending relationship with us routinely hedge, and certain other of those underwriters or their respective affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the Notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the Notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

We have agreed to indemnify the several underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments that the underwriters may be required to make because of any of those liabilities.

Associated Investment Services, Inc., a Financial Industry Regulatory Authority, Inc. ("FINRA") member and an indirect, wholly owned subsidiary of Associated Banc-Corp, is being paid a referral fee by Cabrera Capital Markets LLC.

**Conflicts of Interest**

Certain of the underwriters or their affiliates may hold a portion of the short-term debt that we intend to repay using the net proceeds of the Notes. In such event, it is possible that one or more of the underwriters or their affiliates could receive at least 5% of the net proceeds of the offering, and in that case such underwriter would be deemed to have a conflict of interest under FINRA Rule 5121 (Public Offerings of Securities with Conflicts of Interest). In the event of any such conflict of interest, such underwriter would be required to conduct the distribution of the Notes in accordance with FINRA Rule 5121. If FINRA Rule 5121 is applicable, such underwriter would not be permitted to confirm a sale to an account over which it exercises discretionary authority without first receiving specific written approval from the account holder.

**Legal Matters**

Various legal matters in connection with the Notes will be passed upon (a) for us by Troutman Pepper Locke LLP, Atlanta, Georgia, and (b) for the underwriters by Hunton Andrews Kurth LLP, New York, New York. Joshua M. Erickson, Vice President and Deputy General Counsel, WEC Business Services LLC, will pass upon the validity of the Notes, as well as certain other legal matters, on our behalf. Mr. Erickson is the beneficial owner of less than 0.01% of WEC Energy Group's common stock.

**ABOUT THIS PROSPECTUS**

In this prospectus, "we," "us," "our" and "Wisconsin Public Service" refer to Wisconsin Public Service Corporation, unless the context indicates otherwise.

This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission ("SEC") utilizing a "shelf" registration process. Under this shelf process, we may offer to the public the senior debt securities described in this prospectus in one or more offerings.

This prospectus provides you with only a general description of the senior debt securities we may offer. Each time we offer senior debt securities, we will provide a prospectus supplement to this prospectus that will contain specific information about the particular senior debt securities and terms of that offering. In the prospectus supplement, we will describe the specific designation, aggregate principal amount, purchase price, maturity, rate and time of payment of interest, and the redemption terms and other terms of any senior debt securities that we issue and sell.

The prospectus supplement will also describe the proceeds and uses of proceeds from the senior debt securities, together with the names and compensation of the underwriters, if any, through whom the senior debt securities are being issued and sold, and other important considerations for investors. The prospectus supplement may also add to, update or change information contained in this prospectus.

If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the information in the prospectus supplement. Please carefully read this prospectus and the applicable prospectus supplement, in addition to the information contained in the documents we refer you to under the heading "WHERE YOU CAN FIND MORE INFORMATION."

**RISK FACTORS**

Investing in the senior debt securities of Wisconsin Public Service Corporation involves risk.

Before making an investment decision, you should carefully consider these risks as well as other information contained or incorporated by reference in this prospectus.

**FORWARD-LOOKING STATEMENTS AND CAUTIONARY FACTORS**

We have included or may include statements in this prospectus or in any prospectus supplement (including documents incorporated by reference) that constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended ("Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended ("Exchange Act"). Any statements that express, or involve discussions as to, expectations, beliefs, plans, objectives, goals, strategies, assumptions or future events or performance may be forward-looking statements. Also, forward-looking statements may be identified by reference to a future period or periods or by the use of forward-looking terminology such as "anticipates," "believes," "could," "estimates," "expects," "forecasts," "goals," "guidance," "intends," "may," "objectives," "plans," "possible," "potential," "projects," "seeks," "should," "targets," "will," or similar terms or variations of these terms.

**We caution you that any forward-looking statements are not guarantees of future performance and involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to differ materially from the future results, performance or achievements we have anticipated in the forward-looking statements.**

In addition to the assumptions and other factors referred to specifically in connection with those statements, factors that could cause our actual results, performance or achievements to differ materially from those contemplated in the forward-looking statements include factors we have described under the captions "Cautionary Statement Regarding Forward-Looking Information" and "Risk Factors" in our [Annual Report on Form 10-K for the year ended December 31, 2023](https://www.sec.gov/ix?doc=/Archives/edgar/data/107833/000010781524000099/wps-20231231.htm), and under the caption "Factors Affecting Results, Liquidity, and Capital Resources" in the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section of our [Annual Report on Form 10-K for the year ended December 31, 2023](https://www.sec.gov/ix?doc=/Archives/edgar/data/107833/000010781524000099/wps-20231231.htm), or under similar captions in the other documents we have incorporated by reference. Any forward-looking statement speaks only as of the date on which that statement is made, and, except as required by applicable law, we do not undertake any obligation to update any forward-looking statement to reflect events or circumstances, including unanticipated events, after the date on which that statement is made.

**WISCONSIN PUBLIC SERVICE CORPORATION**

Wisconsin Public Service, an indirect wholly-owned subsidiary of WEC Energy Group, Inc. ("WEC Energy Group"), was incorporated in the state of Wisconsin in 1883. Our principal executive offices are located at 2830 South Ashland Avenue, P.O. Box 19001, Green Bay, Wisconsin 54307-9001, and our telephone number is (800) 450-7260.

We are an electric and natural gas utility and derive revenues primarily from the distribution and sale of electricity and natural gas to retail customers in Wisconsin. We also provide wholesale electric service to numerous utilities and cooperatives for resale. We conduct our business primarily through our utility reportable segment.

**USE OF PROCEEDS**

Except as otherwise described in the applicable prospectus supplement, we intend to use the net proceeds from the sale of our senior debt securities (a) to fund, or repay short-term debt incurred to fund, our continuing construction program to provide services to new and existing utility customers in our service area and to improve and modernize our facilities, (b) to repay and/or refinance debt, (c) for investments, and/or (d) for other general corporate purposes. Pending disposition, we may temporarily invest any proceeds of the offering not required immediately for the intended purposes in U.S. governmental securities and other high quality U.S. securities. We expect to borrow money or sell securities from time to time, but we cannot predict the precise amounts or timing of doing so. For current information, please refer to our current filings with the SEC. See "WHERE YOU CAN FIND MORE INFORMATION."

**DESCRIPTION OF THE SENIOR DEBT SECURITIES**

We may issue from time to time, in one or more series, senior debt securities under a Trust Indenture dated as of December 1, 1998 between us and U.S. Bank Trust Company, National Association (successor to Firstar Bank Milwaukee, N.A., National Association), as supplemented and amended by any supplemental indentures, which we refer to collectively in this prospectus as the "indenture." In this prospectus, we refer to U.S. Bank Trust Company, National Association and any successor trustee under the indenture as the "senior trustee." At March 31, 2024, the aggregate principal amount of senior debt securities outstanding under the indenture was $2.0 billion.

We have summarized selected provisions of the indenture and the senior debt securities that we may offer hereby. Copies of the indenture and a form of supplemental indenture are filed, or incorporated by reference, as exhibits to the registration statement of which this prospectus is a part or other filings incorporated by reference in this prospectus. The supplemental indenture for each series of senior debt securities issued and outstanding also has been or will be filed, or incorporated by reference, as an exhibit to the registration statement or other filings incorporated by reference in this prospectus. You should read the indenture and the applicable supplemental indenture for other provisions that may be important to you. The particular terms of any senior debt securities we offer will be described in the related prospectus supplement, along with any applicable modifications of or additions to the general terms of the senior debt securities described below and in the indenture. For a description of the terms of any series of senior debt securities, you should also review both the prospectus supplement relating to that series and the description of the senior debt securities set forth in this prospectus before making an investment decision.

**General**

The indenture does not contain any debt covenants or provisions that would afford holders of the senior debt securities protection in the event of a highly leveraged transaction.

There is no requirement under the indenture that future issues of our debt securities be issued under the indenture. Subject to certain restrictions, which are described in "Restrictions" below, we will be free to employ other indentures or documentation, containing provisions different from those included in the indenture, in connection with future issues of our debt securities.

Please refer to the prospectus supplement relating to any senior debt securities being offered, which we refer to collectively in this prospectus as the "offered senior debt securities," for specific terms respecting the offered senior debt securities, including among other terms the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the title of the offered senior debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any limit on the aggregate principal amount of the offered senior debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the date or dates on which the offered senior debt securities will mature;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the rate or rates per year (which may be fixed or variable) at which the offered senior debt securities will bear interest or the
method by which the rate or rates will be determined;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the date from which interest will accrue or the method by which that date will be determined;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the dates on which interest will be payable and the regular record dates for the interest payment dates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the dates, if any, on which, and the price or prices at which, we will redeem any offered senior debt securities, pursuant to any
mandatory redemption or sinking fund provisions, and other detailed terms and provisions of any mandatory redemption or sinking funds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the date, if any, after which, and the price or prices at which, we may, or may be required to, redeem any offered senior debt securities,
at our option or the option of the holder, pursuant to any optional redemption provisions, and other detailed terms and provisions of
any optional redemption; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any other terms of any offered senior debt securities (which terms shall not be inconsistent with the indenture).

The following activities relating to the senior debt securities will occur at the office of the senior trustee in St. Paul, Minnesota:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· payment of principal and interest; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· exchange, transfer and registration of certificated senior debt securities.

At the option of the senior trustee, we may pay interest to the registered holder by check or by electronic funds transfer.

The offered senior debt securities will be represented either by global securities registered in the name of a depositary, or its nominee, or by certificates in certificated form issued to the registered holders of the offered senior debt securities as set forth in the applicable prospectus supplement.

**Definitions**

For purposes of the descriptions of the senior debt securities, certain defined terms have the following meanings:

"Capitalization" means the total of all the following items appearing on, or included in, our consolidated balance sheet: (i) liabilities for indebtedness maturing more than 12 months from the date of determination; and (ii) common stock, preferred stock, Hybrid Preferred Securities (as defined in the indenture), premium on capital stock, capital surplus, capital in excess of par value, and retained earnings (however the foregoing may be designated), less, to the extent not otherwise deducted, the cost of shares of our capital stock held in treasury. Subject to the foregoing, Capitalization shall be determined in accordance with generally accepted accounting principles and practices applicable to the type of business in which we are engaged and that are approved by our regularly retained independent accountants, and may be determined as of a date not more than 60 days before the happening of the event for which the determination is being made.

"Debt" means any outstanding debt for money borrowed evidenced by notes, debentures, bonds or other securities or guarantees of any debt for money borrowed.

"Net Tangible Assets" means the amount shown as total assets on our consolidated balance sheet, less the following: (i) intangible assets including, but without limitation, such items as goodwill, trademarks, trade names, patents, and unamortized debt discount and expense and (ii) appropriate adjustments, if any, on account of minority interests. Net Tangible Assets shall be determined in accordance with generally accepted accounting principles and practices applicable to the type of business in which we are engaged and that are approved by our regularly retained independent accountants, and may be determined as of a date not more than 60 days before the happening of the event for which the determination is being made.

"Operating Property" means (i) any interest in real property that we own and (ii) any asset that we own that is depreciable in accordance with generally accepted accounting principles, excluding, in either case, any of our interests as lessee under any lease (except for a lease that results from a Sale and Lease-Back Transaction) which has been or would be capitalized on the books of the lessee in accordance with generally accepted accounting principles.

"Sale and Lease-Back Transaction" means any arrangement with any person providing for the leasing to us of any Operating Property (except for leases for a term, including any renewals, of not more than 48 months), which Operating Property has been or is to be sold or transferred by us to that person. However, a Sale and Lease-Back Transaction shall not include any arrangement first entered into before the date of the indenture or any transaction in which we sell Operating Property to, and subsequently purchase energy or services from, an entity if the transaction was ordered or authorized by, or was entered into pursuant to any plan or program of industry restructuring ordered or authorized by, any regulatory authority with jurisdiction over us or our operations.

"Value" means, with respect to a Sale and Lease-Back Transaction, as of any particular time, the amount equal to the greater of (i) our net proceeds from the sale or transfer of the property leased pursuant to the Sale and Lease-Back Transaction or (ii) the net book value of the property, as determined by us in accordance with generally accepted accounting principles at the time of entering into the Sale and Lease-Back Transaction, in either case multiplied by a fraction, the numerator of which will be equal to the number of full years of the term of the lease that is part of the Sale and Lease-Back Transaction remaining at the time of determination and the denominator of which will be equal to the number of full years of that term, without regard, in any case, to any renewal or extension options contained in the lease.

**Restrictions**

The indenture provides that we may not consolidate with, merge with or into any other corporation (whether or not we are the surviving corporation), or sell, assign, transfer or lease all or substantially all of our properties and assets as an entirety or substantially as an entirety to any person or group of affiliated persons, in one transaction or a series of related transactions, unless: (1) either we will be the continuing person or the person (if other than us) formed by the consolidation or with which or into which we are merged or the person (or group of affiliated persons) to which we sell, assign, transfer or lease all or substantially all our properties and assets is a corporation (or constitute corporations) and that corporation expressly assumes all our obligations under the senior debt securities and the indenture by an indenture supplemental to the indenture, executed and delivered to the senior trustee in form satisfactory to the senior trustee; (2) immediately before and after giving effect to the transaction or series of transactions, no event of default, and no default, with respect to the senior debt securities shall have occurred and be continuing; and (3) we shall have delivered to the senior trustee an officer's certificate and an opinion of counsel, each stating that the consolidation, merger or transfer and the supplemental indenture complies with the indenture.

**Limitation on Liens**

The indenture provides that, so long as any senior debt securities are outstanding, we may not issue, assume, guarantee or permit to exist any Debt that is secured by any mortgage, security interest, pledge or lien, which we refer to collectively in this prospectus as "liens," of or upon any of our Operating Property, whether owned at the date of the indenture or acquired after that date, without in any such case effectively securing the senior debt securities (together with, if we shall so determine, any of our other indebtedness ranking equally with the senior debt securities) equally and ratably with such Debt (but only so long as such Debt is so secured).

That restriction will not apply to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· liens on any Operating Property existing at the time of its acquisition (which liens may also extend to subsequent repairs, alterations
and improvements to the Operating Property);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· liens on Operating Property of a corporation existing at the time the corporation is merged into, or consolidated with, or the corporation
disposes of its properties (or those of a division) as or substantially as an entirety to, us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· liens on Operating Property to secure the cost of acquisition, construction, development or substantial repair, alteration or improvement
of the Operating Property or to secure indebtedness incurred to provide funds for any of those purposes or for reimbursement of funds
previously expended for any of those purposes, provided those liens are created or assumed contemporaneously with, or within 18 months
after, the acquisition or the completion of construction, development or substantial repair, alteration or improvement of the Operating
Property;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· liens in favor of any state or any department, agency or instrumentality or political subdivision of any state, or for the benefit
of holders of securities issued by any of those entities (or providers of credit enhancement with respect to those securities), to secure
any Debt (including, without limitation, any of our obligations with respect to industrial development, pollution control or similar revenue
bonds) incurred for the purpose of financing all or any part of the purchase price or the cost of constructing, developing or substantially
repairing, altering or improving our Operating Property; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any liens referred
to in the foregoing exceptions, provided, however, that the principal amount of Debt secured by the liens and not otherwise authorized
by the foregoing exceptions, will not exceed the principal amount of Debt, plus any premium or fee payable in connection with any such
extension, renewal or replacement, so secured at the time of such extension, renewal or replacement.

In addition, the restriction on liens described in this section will not apply to our issuance, assumption or guarantee of Debt secured by any liens that would otherwise be subject to that restriction up to an aggregate amount which, together with all of our other secured Debt (not including secured Debt permitted under any of the exceptions described above) and the Value of Sale and Lease-Back Transactions existing at that time (other than Sale and Lease-Back Transactions the proceeds of which have been applied to the retirement of certain indebtedness, Sale and Lease-Back Transactions in which the property involved would have been permitted to be subjected to any liens under any of the foregoing exceptions and Sale and Lease-Back Transactions that are permitted by the first sentence of "Limitations on Sale and Lease-Back Transactions" below), does not exceed the greater of 10% of the Net Tangible Assets or 10% of Capitalization.

**Limitations on Sale and Lease-Back Transactions**

The indenture provides that so long as the senior debt securities are outstanding, we may not enter into or permit to exist any Sale and Lease-Back Transaction with respect to any Operating Property (except for transactions involving leases for a term, including renewals, of not more than 48 months), if the purchaser's commitment is obtained more than 18 months after the later of the completion of the acquisition, construction or development of the Operating Property or the placing in operation of the Operating Property or of the Operating Property as constructed or developed or substantially repaired, altered or improved. This restriction will not apply if (a) we would be entitled under any of the exceptions described in the second paragraph under "Limitation on Liens" above to issue, assume, guarantee or permit to exist Debt secured by any liens on the Operating Property without equally and ratably securing the senior debt securities, (b) after giving effect to the Sale and Lease-Back Transaction, we could incur pursuant to the provisions described in the third paragraph under "Limitation on Liens," at least $1.00 of additional Debt secured by liens (other than liens permitted by clause (a)) or (c) we apply within 180 days an amount equal to, in the case of a sale or transfer for cash, the net proceeds (not exceeding the net book value), and, otherwise, an amount equal to the fair value (as determined by our Board of Directors) of the Operating Property so leased to the retirement of our senior debt securities or other Debt ranking senior to or equally with, the senior debt securities, subject to reduction for senior debt securities and such Debt retired during such 180-day period otherwise than pursuant to mandatory sinking fund or prepayment provisions and payments at stated maturity.

**Events of Default and Notice of Default**

The following events of default under the indenture apply to the senior debt securities of any series:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· failure to pay interest on any senior debt security when due and if such failure continues for 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· failure to pay the principal of (or premium, if any, on) any senior debt security when due and payable at maturity, upon redemption
or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· failure to observe or perform any other covenant, warranty or agreement contained in the senior debt securities of that series or
in the indenture (other than a covenant, agreement or warranty included in the indenture solely for the benefit of senior debt securities
other than that series) and such failure continued for 60 days, following receipt of notice of the default from the senior trustee or
holders of at least 25% in aggregate principal amount of the outstanding senior debt securities of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· certain events of bankruptcy, insolvency or reorganization relating to us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· any other event of default with respect to the senior debt securities of a series specified in the prospectus supplement relating
to that series or in the supplemental indenture under which that series of senior debt securities is issued.

The senior trustee shall, within 30 days after the occurrence of any default or event of default with respect to senior debt securities of any series, give the holders of senior debt securities of that series notice of all uncured defaults or events of default known to it (the term default includes any event which after notice or passage of time or both would be an event of default); *provided, however*, that, except in the case of an event of default or a default in payment on any senior debt securities of any series, the senior trustee will be protected in withholding the notice if and so long as the board of directors, the executive committee of the board of directors or responsible officers of the senior trustee in good faith determine that the withholding of the notice is in the interest of the holders of senior debt securities of that series.

If an event of default with respect to senior debt securities of any series (other than due to events of bankruptcy, insolvency or reorganization) occurs and is continuing, the senior trustee or the holders of at least 25% in aggregate principal amount of the outstanding senior debt securities of that series, by notice in writing to us (and to the senior trustee if given by the holders of at least 25% in aggregate principal amount of the senior debt securities of that series) may declare the unpaid principal of and accrued interest to the date of acceleration on all the outstanding senior debt securities of that series to be due and payable immediately and, upon any such declaration, the senior debt securities of that series shall become immediately due and payable.

If an event of default occurs due to bankruptcy, insolvency or reorganization, all unpaid principal of and accrued interest on the outstanding senior debt securities of any series will become immediately due and payable without any declaration or other act on the part of the senior trustee or any holder of any senior debt security of that series.

The holders of not less than a majority of the principal amount of the outstanding senior debt securities of any series may rescind a declaration of acceleration and its consequences with respect to the senior debt securities of that series if (1) all existing events of default, other than the nonpayment of principal of and interest on the senior debt securities of that series that have become due solely by such declaration of acceleration, have been cured or waived; (2) to the extent lawful, interest on overdue interest and on overdue principal that has become due otherwise than by reason of such acceleration has been paid; (3) the rescission would not conflict with any judgment or decree of a court of competent jurisdiction; and (4) all amounts due to the senior trustee under the indenture have been paid. The indenture requires us to file periodic statements with the senior trustee regarding our compliance with certain of the covenants of the indenture and to specify any event of default or defaults with respect to senior debt securities, in performing such covenants, of which the signers of the statements may have knowledge.

**Modification of the Indenture; Waiver**

We and the senior trustee without the consent of any holders may modify the indenture with respect to certain matters, including (i) to cure any ambiguity, defect or inconsistency or to correct or supplement any provision which may be inconsistent with any other provision of the indenture and (ii) to make any change that does not materially adversely affect the interests of any holder of senior debt securities of any series. In addition, we and the senior trustee may modify certain of our rights and obligations and the rights of holders of the senior debt securities with the written consent of the holders of at least a majority in aggregate principal amount of the outstanding senior debt securities of each series affected by the modifications. None of the following modifications, however, will be effective against any holder of any outstanding senior debt securities of any series affected by the modifications without that holder's consent:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· extension of the maturity or reduction of the principal amount of any senior debt securities of the affected series, reduction in
the interest rate or extension of the time for payment of interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· change in the redemption provisions in a manner adverse to any holder of senior debt securities of the affected series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· other modification in the terms of payment of the principal of, or interest on, the senior debt securities of the affected series;
or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· reduction of the percentage required for waivers of defaults or events of default under the indenture or for modification of the indenture.

The holders of not less than a majority in aggregate principal amount of the outstanding senior debt securities of any series may, on behalf of the holders of all senior debt securities of that series, waive any event of default or default under the indenture with respect to that series, except an event of default in the payment of the principal of, or premium, if any, or any interest on, any senior debt security of that series or in respect of a provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding senior debt security of the affected series.

**Defeasance**

We may terminate our substantive obligations under the senior debt securities of any series (except for our obligations to pay the principal of (and premium, if any, on) and the interest on the senior debt securities of that series) by (i) depositing with the senior trustee, under the terms of an irrevocable trust agreement, money or U.S. government obligations sufficient to pay all remaining indebtedness on the senior debt securities of that series, (ii) delivering to the senior trustee either an opinion of counsel or a ruling directed to the senior trustee from the Internal Revenue Service to the effect that the holders of the senior debt securities of that series will not recognize income, gain or loss for federal income tax purposes as a result of the deposit and termination of obligations, and (iii) complying with certain other requirements set forth in the indenture.

**Concerning the Senior Trustee**

Unless otherwise indicated in a prospectus supplement, U.S. Bank Trust Company, National Association (as successor to Firstar Bank, Milwaukee, N.A., National Association) will act as senior trustee and registrar for senior debt securities issued under the indenture, and the senior trustee will also act as transfer agent and paying agent with respect to the senior debt securities. The senior trustee may be removed (i) by the holders of a majority in principal amount outstanding of the series of senior debt securities; and/or (ii) by us in certain circumstances, as more fully described in the indenture. If the senior trustee resigns or is removed or if a vacancy exists in the office of senior trustee for any reason, the indenture provides that we must promptly appoint a successor senior trustee. The senior trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for us or our affiliates, and may otherwise deal with us or our affiliates, as if it were not the senior trustee. The senior trustee also provides services for us and some of our affiliates, including WEC Energy Group, as a depository of funds, registrar, member of bank groups providing back-up credit facilities to us and our affiliates, trustee under other indentures and similar services.
