HomeMy WebLinkAboutA001 - Council Action Form dated August 11, 2026ITEM #:13 DATE:08-11-26 DEPT:FIN SUBJECT:SALE OF GENERAL OBLIGATION CORPORATE PURPOSE BONDS, SERIES 2026C, AND AUTHORIZING PRELIMINARY OFFICIAL STATEMENT COUNCIL ACTION FORM BACKGROUND: The FY 2026/27 Budget includes General Obligation (G.O.) Bond-funded capital improvement projects totaling $45,614,351. In addition, the City intends to borrow $589,725 to reimburse itself for eligible development costs incurred in FY 2025/26 for the Fire Station #2 Relocation Project. Together, these amounts result in total anticipated borrowing of $46,204,076. The proposed bond issuance is currently structured with a par amount of $44,320,000 and an estimated bond premium of $1,884,076, providing total proceeds of $46,204,076. While the City’s annual G.O. Bond issuance traditionally finances projects such as street improvements, shared-use paths, airport improvements, and parks and recreation projects, this year ’s issuance is significantly larger due to the inclusion of the Fire Station #2 Relocation Project and construction of the Resource Recovery and Recycling Campus (R3C). Authorization for the projects included in the issuance is summarized below: Annual Capital Improvements Program (CIP) – On March 24, 2026, as part of the City’s budgeting process, the City Council authorized G.O. Bond funding to support street and traffic improvements, as well as airside and entryway improvements at the James Herman Banning Ames Municipal Airport in an amount not to exceed $17,375,000. Fire Station #2 Relocation – On November 4, 2025, voters approved a public referendum authorizing up to $10,500,000 in G.O. Bond funding to relocate Fire Station #2 from Welch Avenue to a new site along State Avenue. Resource Recovery and Recycling Campus (R3C) – On May 26, 2026, the City Council authorized $24,000,000 in borrowing for construction of the R3C campus. The original financing plan contemplated the issuance of short-term bond anticipation notes. However, the lowest-cost financing proposal received exceeded the anticipated interest rate. Staff, therefore, recommended incorporating the required borrowing into the City’s annual G.O. Bond issuance. To proceed with the bond issuance, the City Council must approve the Preliminary Official Statement, which provides financial and other required disclosures to prospective investors and is on file in the City Clerk’s Office. The Council must also establish the bond sale date, recommended for August 25, 2026, and authorize the use of electronic bidding. Electronic 1 bidding is permitted under Iowa law and provides for a secure and competitive bond sale process. The projects and costs to be financed through the issuance are summarized below: Asphalt Street Pavement Improvements $2,340,000 Arterial Street Pavement Improvements 1,260,000 CyRide Route Pavement Improvements 3,800,000 Concrete Pavement Improvements 3,300,000 Seal Coat Street Pavement Improvements 900,000 Collector Street Pavement Improvements 2,800,000 Freel Drive Paving 975,000 Intelligent Transportation System 178,756 Airport Airside Improvements 623,250 Airport Entryway Improvements 140,000 Total CIP $16,317,006 FY 2025/26 Fire Station #2 Relocation $589,725 FY 2026/27 Fire Station #2 Relocation 6,680,955 Total Fire Station #2 Relocation $7,270,680 R3C Construction (abated by Resource Recovery)$22,000,000 Total Project Funding $45,587,686 Cost of Issuance and Rounding 616,390 Total Proceeds $46,204,076 As noted above, the $46,204,076 in total proceeds is currently estimated to consist of $44,320,000 in par value and $1,884,076 in bond premium. A bond premium occurs when investors pay more than the face value of the bonds because the interest rate paid on the bonds is higher than the market rate at the time of sale. The final amounts of par value and premium will be determined when bids are received on August 25, 2026, however, the combined amount is expected to provide the $46,204,076 necessary to fund the projects and issuance costs identified above. Finally, the required public hearings have already been completed, and the proposed issuance complies with the City’s debt management policy and applicable statutory requirements governing municipal debt. 2 ALTERNATIVES: 1. Adopt a resolution approving the Preliminary Official Statement for General Obligation Corporate Purpose Bonds, Series 2026C, setting the date of sale for August 25, 2026, and authorize electronic bidding for the sale. 2. Refer the Official Statement back to City staff for modifications. CITY MANAGER'S RECOMMENDED ACTION: Issuance of these bonds is necessary to provide funding for the City’s approved Capital Improvements Plan, the Fire Station #2 Relocation Project, and construction of the Resource Recovery and Recycling Campus (R3C).Therefore, it is the recommendation of the City Manager that the City Council adopt Alternative No. 1, as stated above.

In the event a Purchaser fails to honor its accepted bid proposal, any deposit will be retained by the City. FORM OF BIDS AND AWARD All bids shall be unconditional for the entire issue of Bonds for a price not less than $43,876,800, plus accrued interest, and shall specify the rate or rates of interest in conformity to the limitations as set forth in the “BIDDING PARAMETERS” section herein. Bids must be submitted on or in substantial compliance with the “OFFICIAL BID FORM” provided by the City. The Bonds will be awarded to the bidder offering the lowest interest rate to be determined on a true interest cost (the “TIC”) basis assuming compliance with the “ESTABLISHMENT OF ISSUE PRICE” herein, and “GOOD FAITH DEPOSIT” herein. The TIC shall be determined by the present value method, i.e., by ascertaining the semiannual rate, compounded semiannually, necessary to discount to present value as of the dated date of the Bonds, the amount payable on each interest payment date and on each stated maturity date or earlier mandatory redemption, so that the aggregate of such amounts will equal the aggregate purchase price offered therefore. The TIC shall be stated in terms of an annual percentage rate and shall be that rate of interest which is twice the semiannual rate so ascertained (also known as the Canadian Method). The TIC shall be as determined by the Municipal Advisor based on the “TERMS OF OFFERING” and all amendments, and on the bids as submitted. The Municipal Advisor’s computation of the TIC of each bid shall be controlling. In the event of tie bids for the lowest TIC, the Bonds will be awarded by lot. The City will reserve the right to: (i) waive non-substantive informalities of any bid or of matters relating to the receipt of bids and award of the Bonds, (ii) reject all bids without cause, and (iii) reject any bid which the City determines to have failed to comply with the terms herein. BIDDING PARAMETERS Each bidder’s proposal must conform to the following limitations: 1. Each annual maturity must bear a single rate of interest from the dated date of the Bonds to the date of maturity. 2. Rates of interest bid must be in multiples of one-eighth or one-twentieth of one percent. 3. The initial price to the public for each maturity must be 98% or greater. 10 iii RECEIPT OF BIDS Forms of Bids: Bids must be submitted on or in substantial compliance with the “TERMS OF OFFERING” and “OFFICIAL BID FORM” provided by the City or through PARITY® competitive bidding system (the “Internet Bid System”). The City shall not be responsible for malfunction or mistake made by any person, or as a result of the use of an electronic bid or the means used to deliver or complete a bid. The use of such facilities or means is at the sole risk of the prospective bidder who shall be bound by the terms of the bid as received. No bid will be accepted after the time specified in the “OFFICIAL BID FORM”. The time as maintained by the Internet Bid System shall constitute the official time with respect to all bids submitted. A bid may be withdrawn before the bid deadline using the same method used to submit the bid. If more than one bid is received from a bidder, the last bid received shall be considered. Sealed Bidding: Sealed bids may be submitted and will be received at the office of the City’s Treasurer, City Hall, 515 Clark Avenue, Ames, Iowa 50010. Electronic Internet Bidding: Electronic internet bids will be received at the office of the City’s Municipal Advisor, PFM Financial Advisors LLC, Des Moines, Iowa, and at the office of the City’s Treasurer. Electronic internet bids must be submitted through the Internet Bid System. Information about the Internet Bid System may be obtained by calling 212-849-5021. Each bidder shall be solely responsible for making necessary arrangements to access the Internet Bid System for purposes of submitting its electronic internet bid in a timely manner and in compliance with the requirements of the “TERMS OF OFFERING” and “OFFICIAL BID FORM”. The City is permitting bidders to use the services of the Internet Bid System solely as a communication mechanism to conduct the electronic internet bidding and the Internet Bid System is not an agent of the City. Provisions of the “TERMS OF OFFERING” and “OFFICIAL BID FORM” shall control in the event of conflict with information provided by the Internet Bid System. BOOK-ENTRY-ONLY ISSUANCE The Bonds will be issued by means of a book-entry-only system with no physical distribution of bond certificates made to the public. The Bonds will be issued in fully registered form and one bond certificate, representing the aggregate principal amount of the Bonds maturing in each year, will be registered in the name of Cede & Co. as nominee of The Depository Trust Company (“DTC”), New York, New York, which will act as securities depository of the Bonds. Individual purchases of the Bonds may be made in the principal amount of $5,000 or any multiple thereof of a single maturity through book entries made on the books and records of DTC and its participants. Principal and interest are payable by the Registrar to DTC or its nominee as registered owner of the Bonds. Transfer of principal and interest payments to participants of DTC will be the responsibility of DTC; transfer of principal and interest payments to beneficial owners by participants will be the responsibility of such participants and other nominees of beneficial owners. The Purchaser, as a condition of delivery of the Bonds, will be required to deposit the bond certificates with DTC. MUNICIPAL BOND INSURANCE AT PURCHASER’S OPTION If the Bonds qualify for issuance of any policy of municipal bond insurance or commitment therefore at the option of the bidder, the purchase of any such insurance policy or the issuance of any such commitment shall be at the sole option and expense of the Purchaser. Any increased costs of issuance of the Bonds resulting from such purchase of insurance shall be paid by the Purchaser, except that, if the City has requested and received a rating on the Bonds from a rating agency, the City will pay that initial rating fee. Any other rating agency fees shall be the responsibility of the Purchaser. Failure of the municipal bond insurer to issue the policy after the Bonds have been awarded to the Purchaser shall not constitute cause for failure or refusal by the Purchaser to accept delivery on the Bonds. The City reserves the right in its sole discretion to accept or deny changes to the financing documents requested by the insurer selected by the Purchaser. 11 iv DELIVERY The Bonds will be delivered to the Purchaser through DTC in New York, New York, against full payment in immediately available cash or federal funds. The Bonds are expected to be delivered within forty-five days after the sale. Should delivery be delayed beyond sixty days from the date of sale for any reason except failure of performance by the Purchaser, the Purchaser may withdraw their bid and thereafter their interest in and liability for the Bonds will cease. When the Bonds are ready for delivery, the City will give the Purchaser five working days’ notice of the delivery date and the City will expect payment in full on that date; otherwise reserving the right at its option to determine that the Purchaser failed to comply with the offer of purchase. ESTABLISHMENT OF ISSUE PRICE In order to establish the issue price of the Bonds for federal income tax purposes, the City requires bidders to agree to the following, and by submitting a bid, each bidder agrees to the following. If a bid is submitted by a potential underwriter, the bidder confirms that (i) the underwriters have offered or reasonably expect to offer the Bonds to the public on or before the date of the award at the offering price (the “initial offering price”) for each maturity as set forth in the bid and (ii) the bidder, if it is the winning bidder, shall require any agreement among underwriters, selling group agreement, retail distribution agreement or other agreement relating to the initial sale of the Bonds to the public to which it is a party to include provisions requiring compliance by all parties to such agreements with the provisions contained herein. For purposes hereof, Bonds with a separate CUSIP number constitute a separate “maturity,” and the public does not include underwriters of the Bonds (including members of a selling group or retail distribution group) or persons related to underwriters of the Bonds. If, however, a bid is submitted for the bidder’s own account in a capacity other than as an underwriter of the Bonds, and the bidder has no current intention to sell, reoffer, or otherwise dispose of the Bonds, the bidder shall notify the City to that effect at the time it submits its bid and shall provide a certificate to that effect in place of the certificate otherwise required below. If the winning bidder intends to act as an underwriter, the City shall advise the winning bidder at or prior to the time of award whether (i) the competitive sale rule or (ii) the “hold-the-offering price” rule applies. If the City advises the Purchaser that the requirements for a competitive sale have been satisfied and that the competitive sale rule applies, the Purchaser will be required to deliver to the City at or prior to closing a certification, substantially in the form attached hereto as EXHIBIT 1-A, as to the reasonably expected initial offering price as of the award date. If the City advises the Purchaser that the requirements for a competitive sale have not been satisfied and that the hold-the- offering price rule applies, the Purchaser shall (1) upon the request of the City confirm that the underwriters did not offer or sell any maturity of the Bonds to any person at a price higher than the initial offering price of that maturity during the period starting on the award date and ending on the earlier of (a) the close of the fifth business day after the sale date or (b) the date on which the underwriters have sold at least 10% of that maturity to the public at or below the initial offering price; and (2) at or prior to closing, deliver to the City a certification substantially in the form attached hereto as EXHIBIT 1-B, together with a copy of the pricing wire. Any action to be taken or documentation to be received by the City pursuant hereto may be taken or received on behalf of the City by Municipal Advisor. Bidders should prepare their bids on the assumption that the Bonds will be subject to the “hold-the-offering-price” rule. Any bid submitted pursuant to the “TERMS OF OFFERING” and “OFFICIAL BID FORM” shall be considered a firm offer for the purchase of the Bonds, and bids submitted will not be subject to cancellation or withdrawal. 12 v OFFICIAL STATEMENT The City has authorized the preparation of a Preliminary Official Statement containing pertinent information relative to the Bonds. The Preliminary Official Statement will be further supplemented by offering prices, interest rates, selling compensation, aggregate principal amount, principal amount per maturity, anticipated delivery date and underwriter, together with any other information required by law or deemed appropriate by the City, shall constitute a final Official Statement of the City with respect to the Bonds, as that term is defined in Rule 15c2-12 promulgated by the Securities and Exchange Commission under the Securities Exchange Act of 1934, as amended (the “Rule”). By awarding the Bonds to any underwriter or underwriting syndicate submitting an “OFFICIAL BID FORM” therefore, the City agrees that no more than seven (7) business days after the date of such award, it shall provide without cost to the senior managing underwriter of the syndicate to which the Bonds are awarded up to 25 copies of the final Official Statement to permit each “Participating Underwriter” (as that term is defined in the Rule) to comply with the provisions of the Rule. The City shall treat the senior managing underwriter of the syndicate to which the Bonds are awarded as its designated agent for purposes of distributing copies of the final Official Statement to the Participating Underwriter. Any underwriter executing and delivering an “OFFICIAL BID FORM” with respect to the Bonds, agrees thereby, if its bid is accepted by the City, (i) it shall accept such designation, and (ii) it shall enter into a contractual relationship with all Participating Underwriters of the Bonds for purposes of assuring the receipt by each such Participating Underwriter of the final Official Statement. ELECTRONIC EXECUTED DOCUMENTS Purchaser consents to the receipt of electronic transcripts and acknowledges the City’s intended use of electronically executed documents. Chapter 554D of the Iowa Code establishes electronic signatures have the full weight and legal authority as manual signatures. CONTINUING DISCLOSURE The City will covenant in a Continuing Disclosure Certificate for the benefit of the Owners and Beneficial Owners of the Bonds to provide annually certain financial information and operating data relating to the City (the “Annual Report”), and to provide notices of the occurrence of certain enumerated events. The Annual Report is to be filed by the City not later than June 30 after the close of each fiscal year, commencing with the close of the fiscal year ending June 30, 2026, with the Municipal Securities Rulemaking Board, at its internet repository named “Electronic Municipal Market Access” (“EMMA”). The notices of events, if any, are also to be filed with EMMA. See “APPENDIX D – FORM OF CONTINUING DISCLOSURE CERTIFICATE”. The specific nature of the information to be contained in the Annual Report or the notices of events, and the manner in which such materials are to be filed, are summarized in “APPENDIX D – FORM OF CONTINUING DISCLOSURE CERTIFICATE”. These covenants have been made in order to assist the Purchaser in complying with section (b)(5) of the Rule. During the previous five years, the City has not failed to comply, in all material respects, with any previous undertakings it has entered into with respect to the Rule. Regarding the Mary Greeley Medical Center (the “Medical Center”), the Annual Financial Information and Operating Data Report for the Fiscal Year ending June 30, 2021 was not timely filed. Breach of the undertakings will not constitute a default or an “Event of Default” under the Bonds or the resolution for the Bonds. A broker or dealer is to consider a known breach of the undertakings, however, before recommending the purchase or sale of the Bonds in the secondary market. Thus, a failure on the part of the City to observe the undertakings may adversely affect the transferability and liquidity of the Bonds and their market price. CUSIP NUMBERS It is anticipated that Committee on Uniform Security Identification Procedures (“CUSIP”) numbers will be printed on the Bonds and the Purchaser must agree in the bid proposal to pay the cost thereof. In no event will the City, Bond Counsel, Disclosure Counsel or Municipal Advisor be responsible for the review or express any opinion that the CUSIP numbers are correct. Incorrect CUSIP numbers on said Bonds shall not be cause for the Purchaser to refuse to accept delivery of said Bonds.

Inquiries may be made to the City’s Municipal Advisor, PFM Financial Advisors LLC (the “Municipal Advisor”), 801 Grand Avenue, Suite 3300, Des Moines, Iowa, 50309, telephone 515-724-5734. Information may also be obtained from Mr. Roger Wisecup, City Treasurer, City of Ames, 515 Clark Avenue, Ames, Iowa, 50010, telephone 515-239-5119. AUTHORITY AND PURPOSE The Bonds are being issued pursuant to Chapters 384 and 76 of the Code of Iowa, 2025, as amended (collectively, the “Act”), and a resolution expected to be adopted by the City Council of the City on August 25, 2026 (the “Resolution”). The Bonds are being issued for the purpose of paying the cost, to that extent, of (a) undertaking improvements to the municipal right of way, including the construction of street, storm water drainage, sidewalk, sanitary sewer system and water utility system improvements; (b) acquiring and installing street lighting, signage, signalization and traffic control systems and improvements; (c) undertaking surfacing improvements at the municipal airport; (d) constructing furnishing, equipping a new municipal fire station as a replacement for existing Fire Station #2; (e) constructing and equipping a transfer station for the City’s solid waste disposal system; and (f) paying certain costs of issuance related to the Bonds.

INTEREST ON THE BONDS Interest on the Bonds will be payable on June 1, 2027 and semiannually on the 1st day of December and June thereafter. Principal and interest shall be paid to the registered holder of a bond as shown on the records of ownership maintained by the Registrar as of the 15th day of the month preceding the interest payment date (the “Record Date”). Interest will be computed on the basis of a 360-day year of twelve 30-day months and will be rounded pursuant to rules of the Municipal Securities Rulemaking Board. 25 2 REDEMPTION Optional Redemption. Bonds due after June 1, 2034 will be subject to call prior to maturity in whole, or from time to time in part, in any order of maturity and within a maturity by lot on said date or on any date thereafter at the option of the City, upon terms of par plus accrued interest to date of call. Mandatory Sinking Fund Redemption. The Bonds identified below are subject to mandatory redemption (by lot, as selected by the Registrar) on June 1 in each of the years set forth below at a redemption price of 100% of the principal amount thereof to be redeemed, plus accrued interest thereon to the redemption date in the following principal amounts: Term Bond Maturing June 1, 20__ Date Amount June 1, 20__ $________ June 1, 20__ (maturity) $________ Selection of Bonds for Redemption. Bonds subject to redemption (other than mandatory sinking fund redemptions) will be selected in such order of maturity as the Issuer may direct. If less than all of the Bonds of any like maturity are to be redeemed, the particular part of those Bonds to be redeemed shall be selected by the Registrar by lot. Notice of Redemption. Notice of such redemption as aforesaid identifying the Bond or Bonds (or portion thereof) to be redeemed shall be sent by electronic means or mailed by certified mail to the registered owners thereof at the addresses shown on the City’s registration books not less than thirty (30) days prior to such redemption date. Any notice of redemption may contain a statement that the redemption is conditioned upon the receipt by the Registrar of funds on or before the date fixed for redemption sufficient to pay the redemption price of the Bonds so called for redemption, and that if funds are not available, such redemption shall be cancelled by written notice to the owners of the Bonds called for redemption in the same manner as the original redemption notice was sent, provided that such notice of cancellation is to be made at least five days prior to the date fixed for redemption. PAYMENT OF AND SECURITY FOR THE BONDS Pursuant to the Resolution and the Act, the Bonds and the interest thereon are general obligations of the City, and all taxable property within the corporate boundaries of the City is subject to the levy of taxes to pay the principal of and interest on the Bonds without constitutional or statutory limitation as to rate or amount. Section 76.2 of the Code of Iowa, 2025, as amended (the “Iowa Code”), provides that when an Iowa political subdivision issues general obligation bonds, the governing authority of such political subdivision shall, by resolution adopted before issuing the bonds, provide for the assessment of an annual levy upon all the taxable property in the political subdivision sufficient to pay the interest and principal of the bonds. A certified copy of such resolution shall be filed with the County Auditor in which the City is located, giving rise to a duty of the County Auditor to annually enter this levy for collection from the taxable property within the boundaries of the City, until funds are realized to pay the bonds in full. For the purpose of providing for the levy and collection of a direct annual tax sufficient to pay the principal of and interest on the Bonds as the same become due, the Resolution provides for the levy of a tax sufficient for that purpose on all the taxable property in the City in each of the years while the Bonds are outstanding. The City shall file a certified copy of the Resolution with the County Auditor, pursuant to which the County Auditor is instructed to enter for collection and assess the tax authorized. When annually entering such taxes for collection, the County Auditor shall include the same as a part of the tax levy for Debt Service Fund purposes of the City and when collected, the proceeds of the taxes shall be converted into the Debt Service Fund of the City and set aside therein as a special account to be used solely and only for the payment of the principal of and interest on the Bonds and for no other purpose whatsoever. 26 3 Pursuant to the provisions of Section 76.4 of the Iowa Code, each year while the Bonds remain outstanding and unpaid, any funds of the City which may lawfully be applied for such purpose, may be appropriated, budgeted and, if received, used for the payment of the principal of and interest on the Bonds as the same become due, and if so appropriated, the taxes for any given fiscal year as provided for in the Resolution, shall be reduced by the amount of such alternate funds as have been appropriated for said purpose and evidenced in the City’s budget. BOOK-ENTRY-ONLY ISSUANCE The information contained in the following paragraphs of this subsection “BOOK-ENTRY-ONLY ISSUANCE” has been extracted from a schedule prepared by Depository Trust Company (“DTC”) entitled “SAMPLE OFFERING DOCUMENT LANGUAGE DESCRIBING BOOK-ENTRY-ONLY ISSUANCE”. The information in this section concerning DTC and DTC’s book-entry-only system has been obtained from sources that the City believes to be reliable, but the City takes no responsibility for the accuracy thereof. The Depository Trust Company (“DTC”), New York, NY, will act as securities depository for the securities (the “Securities”). The Securities will be issued 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. One fully- registered Security certificate will be issued for each issue of the Securities, each in the aggregate principal amount of such issue, and will be deposited with DTC. If, however, the aggregate principal amount of any issue exceeds $500 million, one certificate will be issued with respect to each $500 million of principal amount, and an additional certificate will be issued with respect to any remaining principal amount of such issue. 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 Securities Exchange Act of 1934. 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 (the “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-only 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 (the “Indirect Participants”). DTC has S&P Global Ratings: AA+. The DTC Rules applicable to its Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com. Purchases of Securities under the DTC system must be made by or through Direct Participants, which will receive a credit for the Securities on DTC’s records. The ownership interest of each actual purchaser of each Security (the “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 purchase. Beneficial Owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct or Indirect Participant through which the Beneficial Owner entered into the transaction. Transfers of ownership interests in the Securities 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 Securities, except in the event that use of the book-entry-only system for the Securities is discontinued. To facilitate subsequent transfers, all Securities 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 27 4 DTC. The deposit of Securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not affect any change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Securities; DTC’s records reflect only the identity of the Direct Participants to whose accounts such Securities 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. Beneficial Owners of Securities may wish to take certain steps to augment the transmission to them of notices of significant events with respect to the Securities, such as redemptions, tenders, defaults, and proposed amendments to the Security documents. For example, Beneficial Owners of Securities may wish to ascertain that the nominee holding the Securities for their benefit has agreed to obtain and transmit notices to Beneficial Owners. In the alternative, Beneficial Owners may wish to provide their names and addresses to the registrar and request that copies of notices be provided directly to them. Redemption notices shall be sent to DTC. If less than all of the Securities within an issue are being redeemed, DTC’s practice is to determine by lot the amount of the interest of each Direct Participant in such issue to be redeemed. Neither DTC nor Cede & Co., nor any other DTC nominee, will consent or vote with respect to Securities unless authorized by a Direct Participant in accordance with DTC’s MMI Procedures. Under its usual procedures, DTC mails an Omnibus Proxy to the City 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 Securities are credited on the record date identified in a listing attached to the Omnibus Proxy. Redemption proceeds, distributions, and dividend payments on the Securities 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 the City or Agent, on payable 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 accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such Participant and not of DTC, Agent, or the City, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds, distributions, and dividend payments to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is the responsibility of the City or Agent, disbursement of such payments to Direct Participants will be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners will be the responsibility of Direct and Indirect Participants. A Beneficial Owner shall give notice to elect to have its Securities purchased or tendered, through its Participant, to Remarketing Agent, and shall effect delivery of such Securities by causing the Direct Participant to transfer the Participant’s interest in the Securities, on DTC’s records, to Remarketing Agent. The requirement for physical delivery of Securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the Securities are transferred by Direct Participants on DTC’s records and followed by a book-entry-only credit of tendered Securities to Remarketing Agent’s DTC account. DTC may discontinue providing its services as depository with respect to the Securities at any time by giving reasonable notice to the City or Agent. Under such circumstances, in the event that a successor depository is not obtained, Security certificates are required to be printed and delivered. The City may decide to discontinue use of the system of book-entry-only transfers through DTC (or a successor securities depository). In that event, Security certificates will be printed and delivered to DTC. The information in this section concerning DTC and DTC’s book-entry-only system has been obtained from sources that the City believes to be reliable, but the City takes no responsibility for the accuracy thereof. 28 5 FUTURE FINANCING The City does not anticipate issuing any additional general obligation debt within 90 days of the issuance of the Bonds. However, the City does anticipate issuing approximately $50,805,000 of Electric Revenue Bonds in fall 2026 to be repaid solely and only from the net revenues of the electric enterprise fund. The anticipated fall 2026 electric revenue issuance is part of a larger, $190,000,000, project; however, the next financing is not expected to occur for another 18 months. LITIGATION The City encounters litigation occasionally, as a course of business; however, no litigation currently exists that is not believed to be covered by current insurance carriers and the City is not aware of any threatened or pending litigation affecting the validity of the Bonds or the City’s ability to meet its financial obligations. DEBT PAYMENT HISTORY The City knows of no instance in which it has defaulted in the payment of principal and interest on its debt. LEGAL MATTERS Legal matters incident to the authorization, issuance and sale of the Bonds and with regard to the tax-exempt status of the interest thereon (see “TAX EXEMPTION AND RELATED TAX MATTERS” herein) are subject to the approving legal opinion of Dorsey & Whitney LLP, Des Moines, Iowa, Bond Counsel, a form of which is attached hereto as APPENDIX B to this Preliminary Official Statement. Signed copies of the opinion, dated and premised on law in effect as of the date of original delivery of the Bonds, will be delivered to the purchaser at the time of such original delivery. The Bonds are offered subject to prior sale and to the approval of legality of the Bonds by Bond Counsel. Dorsey & Whitney LLP is also serving as Disclosure Counsel to the Issuer in connection with issuance of the Bonds. The legal opinion to be delivered will express the professional judgment of Bond Counsel, and by rendering a legal opinion, Bond Counsel does not become an insurer or guarantor of the result indicated by that expression of professional judgment of the transaction or the future performance of the parties to the transaction.” TAX EXEMPTION AND RELATED TAX MATTERS Federal Income Tax Exemption: The opinion of Bond Counsel will state that under present laws and rulings, interest on the Bonds is excluded from gross income for federal income tax purposes and is not an item of tax preference for purposes of the federal alternative minimum tax imposed on noncorporate taxpayers under the Internal Revenue of 1986 Code (the “Code”). The opinion set forth in the preceding sentence will be subject to the condition that the Issuer comply with all requirements of the Code that must be satisfied subsequent to the issuance of the Bonds in order that interest thereon be, or continue to be, excluded from gross income for federal income tax purposes. Failure to comply with certain of such requirements may cause the inclusion of interest on the Bonds in gross income for federal income tax purposes to be retroactive to the date of issuance of the Bonds. In the resolution authorizing the issuance of the Bonds, the Issuer will covenant to comply with all such requirements. There may be certain other federal tax consequences to the ownership of the Bonds by certain taxpayers, including without limitation, corporations subject to the branch profits tax, financial institutions, certain insurance companies, certain S corporations, individual recipients of Social Security and Railroad Retirement benefits, taxpayers who may be deemed to have incurred (or continued) indebtedness to purchase or carry tax-exempt obligations, and corporations that may be subject to the alternative minimum tax. Bond Counsel will express no opinion with respect to other federal tax consequences to owners of the Bonds. Prospective purchasers of the Bonds should consult with their tax advisors as to such matters. 29 6 Ownership of the Bonds may result in other state and local tax consequences to certain taxpayers. Bond Counsel expresses no opinion regarding any such collateral consequences arising with respect to the Bonds. Prospective purchasers of the Bonds should consult their tax advisors regarding the applicability of any such state and local taxes. Proposed Changes in Federal and State Tax Law: From time to time, there are Presidential proposals, proposals of various federal committees, and legislative proposals in the Congress and in the states that, if enacted, could alter or amend the federal and state tax matters referred to herein or adversely affect the marketability or market value of the Bonds or otherwise prevent holders of the Bonds from realizing the full benefit of the tax exemption of interest on the Bonds. Further, such proposals may impact the marketability or market value of the Bonds simply by being proposed. No prediction is made whether such provisions will be enacted as proposed or concerning other future legislation affecting the tax treatment of interest on the Bonds. In addition, regulatory actions are from time to time announced or proposed and litigation is threatened or commenced which, if implemented or concluded in a particular manner, could adversely affect the market value, marketability or tax exempt status of the Bonds. It cannot be predicted whether any such regulatory action will be implemented, how any particular litigation or judicial action will be resolved, or whether the Bonds would be impacted thereby. Purchasers of the Bonds should consult their tax advisors regarding any pending or proposed legislation, regulatory initiatives or litigation. The opinions expressed by Bond Counsel are based upon existing legislation and regulations as interpreted by relevant judicial and regulatory authorities as of the date of issuance and delivery of the Bonds, and Bond Counsel has expressed no opinion as of any date subsequent thereto or with respect to any proposed or pending legislation, regulatory initiatives or litigation. Original Issue Discount: The Bonds maturing in the years ________________ (collectively, the “Discount Bonds”) are being sold at a discount from the principal amount payable on such Discount Bonds at maturity. The difference between the price at which a substantial amount of the Discount Bonds of a given maturity is first sold to the public (the “Issue Price”) and the principal amount payable at maturity constitutes “original issue discount” under the Code. The amount of original issue discount that accrues to a holder of a Discount Bond under Section 1288 (“Section 1288”) of the Code is excluded from federal gross income to the same extent that stated interest on such Discount Bond would be so excluded. The amount of the original issue discount that accrues with respect to a Discount Bond under Section 1288 is added to the owner’s federal tax basis in determining gain or loss upon disposition of such Discount Bond (whether by sale, exchange, redemption or payment at maturity). Interest in the form of original issue discount accrues under Section 1288 pursuant to a constant yield method that reflects semiannual compounding on dates that are determined by reference to the maturity date of the Discount Bond. The amount of original issue discount that accrues for any particular semiannual accrual period generally is equal to the excess of (1) the product of (a) one-half of the yield on such Discount Bonds (adjusted as necessary for an initial short period) and (b) the adjusted issue price of such Discount Bonds, over (2) the amount of stated interest actually payable. For purposes of the preceding sentence, the adjusted issue price is determined by adding to the Issue Price for such Discount Bonds the original issue discount that is treated as having accrued during all prior semiannual accrual periods. If a Discount Bond is sold or otherwise disposed of between semiannual compounding dates, then the original issue discount that would have accrued for that semiannual accrual period for federal income tax purposes is allocated ratably to the days in such accrual period. An owner of a Discount Bond who disposes of such Discount Bond prior to maturity should consult owner’s tax advisor as to the amount of original issue discount accrued over the period held and the amount of taxable gain or loss upon the sale or other disposition of such Discount Bond prior to maturity. Owners who purchase Discount Bonds in the initial public offering but at a price different than the Issue Price should consult their own tax advisors with respect to the tax consequences of the ownership of Discount Bonds. The Code contains provisions relating to the accrual of original issue discount in the case of subsequent purchasers of bonds such as Discount Bonds. Owners who do not purchase Discount Bonds in the initial offering should consult their own tax advisors with respect to the tax consequences of the ownership of the Discount Bonds. 30 7 Original issue discount that accrues in each year to an owner of a Discount Bond may result in collateral federal income tax consequences to certain taxpayers. No opinion is expressed as to state and local income tax treatment of original issue discount. All owners of Discount Bonds should consult their own tax advisors with respect to the federal, state, local and foreign tax consequences associated with the purchase, ownership, redemption, sale or other disposition of Discount Bonds. Original Issue Premium: The Bonds maturing in the years _____________ are being issued at a premium to the principal amount payable at maturity. Except in the case of dealers, which are subject to special rules, Bondholders who acquire the Bonds at a premium must, from time to time, reduce their federal tax bases for the Bonds for purposes of determining gain or loss on the sale or payment of such Bonds. Premium generally is amortized for federal income tax purposes on the basis of a bondholder’s constant yield to maturity or to certain call dates with semiannual compounding. Bondholders who acquire any Bonds at a premium might recognize taxable gain upon sale of the Bonds, even if such Bonds are sold for an amount equal to or less than their original cost. Amortized premium is not deductible for federal income tax purposes. Bondholders who acquire any Bonds at a premium should consult their tax advisors concerning the calculation of bond premium and the timing and rate of premium amortization, as well as the state and local tax consequences of owning and selling the Bonds acquired at a premium. BONDHOLDER’S RISKS An investment in the Bonds involves an element of risk. In order to identify risk factors and make an informed investment decision, potential investors should be thoroughly familiar with this entire Preliminary Official Statement (including the appendices hereto) in order to make a judgment as to whether the Bonds are an appropriate investment. Tax Levy Procedures: The Bonds are general obligations of the City, payable from and secured by a continuing ad- valorem tax levied against all of the taxable property within the boundaries of the City. As part of the budgetary process of the City, each fiscal year the City will have an obligation to request a debt service levy to be applied against all of the taxable property within the boundaries of the City. A failure on the part of the City to make a timely levy request, or a levy request by the City that is inaccurate or is insufficient to make full payments of the debt service on the Bonds for a particular fiscal year, may cause Bondholders to experience delay in the receipt of distributions of principal of and/or interest on the Bonds. Changes in Property Taxation: From time to time the Iowa General Assembly has altered the method of property taxation and could do so again. Any alteration in property taxation structure could affect property tax revenues available to pay the Bonds. Historically, the Iowa General Assembly has applied changes in property taxation structure on a prospective basis; however, there is no assurance that future changes in property taxation structure by the Iowa General Assembly will not be retroactive. It is impossible to predict the outcome of future property tax changes by the Iowa General Assembly or their potential negative impact, if any, on the Bonds and the security for the Bonds. Matters Relating to Enforceability of Agreements: Bondholders shall have and possess all the rights of action and remedies afforded by the common law, the Constitution and statutes of the State of Iowa and of the United States of America for the enforcement of payment of the Bonds, including, but not limited to, the right to a proceeding in law or in equity by suit, action or mandamus to enforce and compel performance of the duties required by Iowa law and the Resolution. The practical realization of any rights upon any default will depend upon the exercise of various remedies specified in the Resolution or the Loan Agreement. The remedies available to the Bondholders upon an event of default under the Resolution or the Loan Agreement, in certain respects, may require judicial action, which is often subject to discretion and delay. Under existing law, including specifically the federal bankruptcy code, certain of the remedies specified in the Loan Agreement or the Resolution may not be readily available or may be limited. A court may decide not to order the specific performance of the covenants contained in these documents. The legal opinions to be delivered concurrently with the delivery of the Bonds will be qualified as to the enforceability of the various legal instruments by limitations 31 8 imposed by general principles of equity and public policy and by bankruptcy, reorganization, insolvency or other similar laws affecting the rights of creditors generally. No representation is made, and no assurance is given, that the enforcement of any remedies will result in sufficient funds to pay all amounts due under the Resolution or the Loan Agreement, including principal of and interest on the Bonds. Secondary Market: There can be no guarantee there will be a secondary market for the Bonds or, if a secondary market exists, that such Bonds can be sold for any particular price. Occasionally, because of general market conditions or because of adverse history of economic prospects connected with a particular issue, secondary marketing practices in connection with a particular note or bond issue are suspended or terminated. Additionally, prices of bond or note issues for which a market is being made will depend upon then prevailing circumstances. Such prices could be substantially different from the original purchase price of the Bonds. EACH PROSPECTIVE PURCHASER IS RESPONSIBLE FOR ASSESSING THE MERITS AND RISKS OF AN INVESTMENT IN THE BONDS AND MUST BE ABLE TO BEAR THE ECONOMIC RISK OF SUCH INVESTMENT. THE SECONDARY MARKET FOR THE BONDS, IF ANY, COULD BE LIMITED. Rating Loss: Moody’s Investors Service (“Moody’s”) has assigned a rating of ‘___’ to the Bonds. Generally, a rating agency bases its rating on the information and materials furnished to it and on investigations, studies and assumptions of its own. There is no assurance the rating will continue for any given period of time, or that such rating will not be revised, suspended or withdrawn, if, in the judgment of Moody’s, circumstances so warrant. A revision, suspension or withdrawal of a rating may have an adverse effect on the market price of the Bonds. Bankruptcy and Insolvency: The rights and remedies provided in the Resolution for the Bonds may be limited by and are subject to the provisions of federal bankruptcy laws, to other laws or equitable principles that may affect the enforcement of creditor’s rights, to the exercise of judicial discretion in appropriate cases and to limitations in legal remedies against exercise of judicial discretion in appropriate cases and to limitations on legal remedies against municipal corporations in the State of Iowa. The various opinions of counsel to be delivered with respect to the Bonds, the Loan Agreement and the Resolution for the Bonds, including the opinion of Bond Counsel, will be similarly qualified. If the City were to file a petition under chapter nine of the federal bankruptcy code, the owners of the Bonds could be prohibited from taking any steps to enforce their rights under the Resolution for the Bonds. In the event the City fails to comply with its covenants under the Resolution for the Bonds or fails to make payments on the Bonds, there can be no assurance of the availability of remedies adequate to protect the interests of the holders of the Bonds. Under sections 76.16 and 76.16A of the Iowa Code, a city, county, or other political subdivision may become a debtor under Chapter 9 of the Federal bankruptcy code, if it is rendered insolvent, as defined in 11 U.S.C. §101(32)(c), as a result of a debt involuntarily incurred. As used therein, “debt” means an obligation to pay money, other than pursuant to a valid and binding collective bargaining agreement or previously authorized bond issue, as to which the governing body of the city, county, or other political subdivision has made a specific finding set forth in a duly adopted resolution of each of the following: (1) all or a portion of such obligation will not be paid from available insurance proceeds and must be paid from an increase in general tax levy; (2) such increase in the general tax levy will result in a severe, adverse impact on the ability of the city, county, or political subdivision to exercise the powers granted to it under applicable law, including without limitation providing necessary services and promoting economic development; (3) as a result of such obligation, the city, county, or other political subdivision is unable to pay its debts as they become due; and (4) the debt is not an obligation to pay money to a city, county, entity organized pursuant to chapter 28E of the Iowa Code, or other political subdivision. Forward-Looking Statements: This Preliminary Official Statement contains statements relating to future results that are “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995. When used in this Preliminary Official Statement, the words “anticipated,” “plan,” “expect,” “projected,” “estimate,” “budget,” “pro forma,” “forecast,” “intend,” and similar expressions identify forward-looking statements. Any forward-looking statement is subject to uncertainty. Accordingly, such statements are subject to risks that could cause actual results to differ, possibly materially, from those contemplated in such forward-looking statements. Inevitably, some assumptions used to develop 32 9 forward-looking statements will not be realized or unanticipated events and circumstances may occur. Therefore, investors should be aware that there are likely to be differences between forward-looking statements and the actual results. These differences could be material and could impact the availability of funds of the City to pay debt service when due on the Bonds. Cybersecurity: The City, like many other public and private entities, relies on a large and complex technology environment to conduct its operations. As such, it may face multiple cybersecurity threats including but not limited to, hacking, viruses, malware and other attacks on computer or other sensitive digital systems and networks. There can be no assurances that any security and operational control measures implemented by the Issuer will be completely successful to guard against and prevent cyber threats and attacks. Failure to properly maintain functionality, control, security, and integrity of the City’s information systems could impact business operations and systems, and the costs of remedying any such damage could be significant. The City maintains cybersecurity insurance coverage. The City cannot predict whether this coverage would be sufficient in the event of a cyber-incident. Tax Matters and Loss of Tax Exemption: As discussed under the heading “TAX EXEMPTION AND RELATED TAX MATTERS” herein, the interest on the Bonds could become includable in gross income for purposes of federal income taxation retroactive to the date of delivery of the Bonds, as a result of acts or omissions of the City in violation of its covenants in the Resolution. Should such an event of taxability occur, the Bonds would not be subject to a special redemption and would remain outstanding until maturity or until redeemed under the redemption provisions contained in the Bonds, and there is no provision for an adjustment of the interest rate on the Bonds. It is possible that actions of the City after the closing of the Bonds will alter the tax exempt status of the Bonds, and, in the extreme, remove the tax-exempt status from the Bonds. In that instance, the Bonds are not subject to mandatory prepayment, and the interest rate on the Bonds does not increase or otherwise reset. A determination of taxability on the Bonds, after closing of the Bonds, could materially adversely affect the value and marketability of the Bonds. Risk of Audit: The Internal Revenue Service has an ongoing program to audit tax-exempt obligations to determine the legitimacy of the tax status of such obligations. No assurance can be given as to whether the Internal Revenue Service will commence an audit of the Bonds. Public awareness of any audit could adversely affect the market value and liquidity of the Bonds during the pendency of the audit, regardless of the ultimate outcome of the audit. DTC-Beneficial Owners: Beneficial Owners of the Bonds may experience some delay in the receipt of distributions of principal of and interest on the Bonds since such distributions will be forwarded by the Paying Agent to DTC and DTC will credit such distributions to the accounts of the Participants which will thereafter credit them to the accounts of the Beneficial Owner either directly or indirectly through indirect Participants. Neither the City nor the Paying Agent will have any responsibility or obligation to assure that any such notice or payment is forwarded by DTC to any Participants or by any Participant to any Beneficial Owner. In addition, since transactions in the Bonds can be effected only through DTC Participants, indirect participants and certain banks, the ability of a Beneficial Owner to pledge the Bonds to persons or entities that do not participate in the DTC system, or otherwise to take actions in respect of such Bonds, may be limited due to lack of a physical certificate. Beneficial Owners will be permitted to exercise the rights of registered Owners only indirectly through DTC and the Participants. See “BOOK-ENTRY-ONLY ISSUANCE” herein. Proposed Federal Tax Legislation: From time to time, Presidential proposals, federal legislative committee proposals or legislative proposals are made that would, if enacted, alter or amend one or more of the federal tax matters described herein in certain respects or would adversely affect the market value of the Bonds. It cannot be predicted whether or in what forms any of such proposals that may be introduced, may be enacted and there can be no assurance that such proposals will not apply to the Bonds. See “TAX EXEMPTION AND RELATED TAX MATTERS” herein. Pension and Other Post-Employment Benefits (“OPEB”) Information: The City contributes to the Iowa Public Employees’ Retirement System (“IPERS”), which is a state-wide multiple-employer cost-sharing defined benefit pension 33 10 plan administered by the State of Iowa. IPERS provides retirement and death benefits which are established by State statute to plan members and beneficiaries. All full-time employees of the Issuer not covered by MFPRSI (defined herein) are required to participate in IPERS. IPERS plan members are required to contribute a percentage of their annual salary, in addition to the Issuer being required to make monthly contributions to IPERS. Contribution amounts are set by State statute. The IPERS Actuarial Valuation Report as of June 30, 2025 indicates the funded ratio of IPERS was 92.17%, and the unfunded actuarial liability was $3.841 billion. The Annual Comprehensive Financial Report for its Fiscal Year ended June 30, 2025 (the “IPERS ACFR”) identifies the IPERS net pension liability/(asset) at June 30, 2025, at approximately $2.323 billion (market value), while its net pension liability/(asset) at June 30, 2024 was approximately $3.641 billion (market value). The IPERS ACFR is available on the IPERS website, or by contacting IPERS at 7401 Register Drive, Des Moines, IA 50321. See “APPENDIX C – JUNE 30, 2025 ANNUAL COMPREHENSIVE FINANCIAL REPORT” for additional information on IPERS. However, the information presented in such financial reports or on such websites is not incorporated into this Preliminary Official Statement by any references. Bond Counsel, Disclosure Counsel, the Municipal Advisor, the Underwriter and the City undertake no responsibility for and make no representations as to the accuracy or completeness of the information available from the IPERS discussed above or included on the IPERS website, including, but not limited to, updates of such information on the State Auditor’s website or links to other internet sites accessed through the IPERS website. In the Fiscal Year ended June 30, 2025, the City’s IPERS contribution totaled approximately $12,000,767. The City is current in its obligations to IPERS. At June 30, 2025, the City reported a liability of $13,258,124 for its proportionate share of the net pension liability. While the City’s contributions to IPERS are controlled by state law, there can be no assurance the City will not be required by changes in State law to increase its contribution requirement in the future, which may have the effect of negatively impacting the finances of the City. See “EMPLOYEES AND PENSIONS” included in APPENDIX A to this Preliminary Official Statement, and “JUNE 30, 2025 ANNUAL COMPREHENSIVE FINANCIAL REPORT” included in APPENDIX C to this Preliminary Official Statement for additional information on pension and liabilities of the City. The City contributes to Municipal Fire and Police Retirement System of Iowa (“MFPRSI”), which is a multiple-employer cost-sharing defined benefit pension plan for fire fighters and police officers, administered under Chapter 411 of the Code of Iowa. MFPRSI plan members are required to contribute a percentage of their annual salary, in addition to the City being required to make annual contributions to MFPRSI. Contribution amounts are set by State statute. The MFPRSI Actuarial Valuation Report indicates that as of July 1, 2025, the date of the most recent actuarial valuation for MFPRSI, the funded ratio of MFPRSI was 85.42%, and the unfunded actuarial liability was $603.8 million. The MFPRSI Financial Statements for its Fiscal Year ended June 30, 2025 (the “MFPRSI Report”) identifies the MFPRSI Net Pension Liability at June 30, 2025, at approximately $645.6 million (market value), while its net pension liability at June 30, 2024 was approximately $660.8 million (market value). The MFPRSI Report is available on the MFPRSI website. See “EMPLOYEES AND PENSIONS” included in APPENDIX A to this Preliminary Official Statement, and “JUNE 30, 2025 ANNUAL COMPREHENSIVE FINANCIAL REPORT” included in APPENDIX C to this Preliminary Official Statement for additional information on MFPRSI. In the Fiscal Year ended June 30, 2025, the City’s MFPRSI contribution totaled approximately $2,225,933. The City is current in its obligations to MFPRSI. At June 30, 2025, the City reported a liability of $16,454,725 for its proportionate share of the net pension liability. While the City’s contributions to MFPRSI are controlled by state law, there can be no assurance the City will not be required by changes in State law to increase its contribution requirement in the future, which may have the effect of negatively impacting the finances of the City. See “EMPLOYEES AND PENSIONS” included in APPENDIX A to this Preliminary Official Statement, and “JUNE 30, 2025 ANNUAL COMPREHENSIVE FINANCIAL REPORT” included in APPENDIX C to this Preliminary Official Statement for additional information on pension and liabilities of the City. 34 11 Bond Counsel, Disclosure Counsel, the Municipal Advisor, the Underwriter and the City undertake no responsibility for and make no representations as to the accuracy or completeness of the information available from the MFPRSI discussed above or included on the MFPRSI website, including, but not limited to, updates of such information on the State Auditor’s website or links to other Internet sites accessed through the MFPRSI website. The City provides health and dental care benefits for retirees and their beneficiaries through a single-employer, defined benefit plan. No assets are accumulated in a trust that meets the criteria in paragraph 4 of GASB Statement No. 75. The City has the authority to establish and amend benefit provisions of the plan. Participants must be age 55 or older, have been employed by the City for the preceding four years, and be enrolled in a sponsored insurance plan at the time of retirement. Retirees under age 65 pay the same premium for the medical, prescription drug, and dental benefits as active employees, which results in an implicit rate subsidy and an OPEB liability. The contribution requirements of the City are established and may be amended by the City. Plan members are currently not required to contribute. The City funds on a pay-as-you-go basis. At June 30, 2024, 601 active employees and 20 inactive employees or beneficiaries were covered by the City's benefit terms. The City's total OPEB liability of $4,945,916 was measured as of June 30, 2025 and was determined by an actuarial valuation as June 30, 2024. For additional information, see “OTHER POST-EMPLOYMENT BENEFITS” included in APPENDIX A to this Preliminary Official Statement, and “JUNE 30, 2025 ANNUAL COMPREHENSIVE FINANCIAL REPORT” included in APPENDIX C to this Preliminary Official Statement. Summary: The foregoing is intended only as a summary of certain risk factors attendant to an investment in the Bonds. In order for potential investors to identify risk factors and make an informed investment decision, potential investors should become thoroughly familiar with this entire Preliminary Official Statement and the appendices hereto. RATING The Bonds have been rated ‘___’ by Moody’s. Currently, Moody’s rates the City’s outstanding General Obligation long- term debt ‘Aa1’. The existing rating on long-term debt reflects only the view of the rating agency and any explanation of the significance of such rating may only be obtained from Moody’s. The ratings described above are not recommendations to buy, sell or hold the Bonds. There is no assurance that any such rating will continue for any period of time or that it will not be revised downward or withdrawn entirely if, in the judgment of Moody’s, circumstances so warrant. Therefore, after the date hereof, investors should not assume that the ratings are still in effect. A downward revision or withdrawal of either rating is likely to have an adverse effect on the market price and marketability of the Bonds. The City has not assumed any responsibility either to notify the owners of the Bonds of any proposed change in or withdrawal of any rating subsequent to the date of this Preliminary Official Statement, except in connection with the reporting of events as provided in the Continuing Disclosure Certificate, or to contest any revision or withdrawal. MUNICIPAL ADVISOR The City has retained PFM Financial Advisors LLC, Des Moines, Iowa as Municipal Advisor in connection with the preparation of the issuance of the Bonds. In preparing the Preliminary Official Statement, the Municipal Advisor has relied on government officials and other sources to provide accurate information for disclosure purposes. The Municipal Advisor is not obligated to undertake, and has not undertaken, an independent verification of the accuracy, completeness or fairness of the information contained in this Preliminary Official Statement. PFM Financial Advisors LLC is an independent advisory firm and is not engaged in the business of underwriting, trading or distributing municipal securities or other public securities. UNDERWRITING The Bonds are being purchased, subject to certain conditions, by __________________ (the “Underwriter”). The Underwriter has agreed, subject to certain conditions, to purchase all, but not less than all, of the Bonds at an aggregate purchase price of $_________ (reflecting the par amount of the Bonds with original issue premium of $_________ and an underwriter’s discount of $_________). The Underwriter may offer and sell the Bonds to certain dealers (including dealers depositing the Bonds into unit investment trusts, certain of which may be sponsored or managed by the Underwriter) at prices lower than the initial 35 12 public offering prices stated on the cover page. The initial public offering prices of the Bonds may be changed, from time to time, by the Underwriter. The Underwriter intends to engage in secondary market trading of the Bonds subject to applicable securities laws. The Underwriter is not obligated, however, to repurchase any of the Bonds at the request of the holder thereof. CONTINUING DISCLOSURE The City will covenant in a Continuing Disclosure Certificate for the benefit of the owners and beneficial owners of the Bonds to provide annually certain financial information and operating data relating to the City (the “Annual Report”), and to provide notices of the occurrence of certain enumerated events. The Annual Report is to be filed by the City no later than June 30 after the close of each fiscal year, commencing with the fiscal year ending June 30, 2026, with the Municipal Securities Rulemaking Board, at its internet repository named “Electronic Municipal Market Access” (“EMMA”). The notices of events, if any, are also to be filed with EMMA. See “FORM OF CONTINUING DISCLOSURE CERTIFICATE” included in APPENDIX D to this Preliminary Official Statement The specific nature of the information to be contained in the Annual Report or the notices of events, and the manner in which such materials are to be filed, are summarized in the “FORM OF CONTINUING DISCLOSURE CERTIFICATE.” These covenants have been made in order to assist the Underwriter in complying with SEC Rule 15c2-12(b)(5) (the “Rule”). During the previous five years, the City has not failed to comply, in all material respects, with any previous undertakings it has entered into with respect to the Rule. Regarding the Mary Greeley Medical Center (the “Medical Center”), the Annual Financial Information and Operating Data Report for the Fiscal Year ending June 30, 2021 was not timely filed. Breach of the undertakings will not constitute a default or an “Event of Default” under the Bonds or the Resolution. A broker or dealer is to consider a known breach of the undertakings, however, before recommending the purchase or sale of the Bonds in the secondary market. Thus, a failure on the part of the City to observe the undertakings may adversely affect the transferability and liquidity of the Bonds and their market price. FINANCIAL STATEMENTS The City’s “JUNE 30, 2025 ANNUAL COMPREHENSIVE FINANCIAL REPORT”, as prepared by City management and audited by a certified public accountant, is reproduced as APPENDIX C. The City’s certified public accountant has not consented to distribution of the audited financial statements and has not been engaged to perform, and has not performed, any procedures on the financial statements after June 30, 2025, and also has not performed any procedures relating to this Official Statement. Further information regarding financial performance and copies of the City’s prior Annual Comprehensive Financial Report may be obtained from PFM Financial Advisors LLC. MISCELLANEOUS Brief descriptions or summaries of the Issuer, the Bonds, the Resolution and other documents, agreements and statutes are included in this Official Statement. The summaries or references herein to the Bonds, the Resolution and other documents, agreements and statutes referred to herein, and the description of the Bonds included herein, do not purport to be comprehensive or definitive, and such summaries, references and descriptions are qualified in their entireties by reference to such documents, and the description herein of the Bonds is qualified in its entirety by reference to the form thereof and the information with respect thereto included in the aforesaid documents.

CITY OF AMES, IOWA Roger Wisecup, City Treasurer 37 APPENDIX A GENERAL INFORMATION ABOUT THE CITY OF AMES, IOWA The $44,320,000* GENERAL OBLIGATION CORPORATE PURPOSE BONDS, SERIES 2026C (the “Bonds”) are general obligations of the City of Ames, Iowa (the “City”) for which the City will pledge its power to levy direct ad valorem taxes against all taxable property within the City without limitation as to rate or amount to the repayment of the Bonds. * Preliminary, subject to change. 38 A-1 CITY PROPERTY VALUATIONS IOWA PROPERTY VALUATIONS In compliance with Section 441.21 of the Code of Iowa, the State Director of Revenue annually directs the county auditors to apply prescribed statutory percentages to the assessments of certain categories of real property. The 2025 final Actual Values were adjusted by the Story County Auditor. The reduced values, determined after the application of rollback percentages, are the taxable values subject to tax levy. For assessment year 2025 (applicable to fiscal year 2026-27), the taxable value rollback rate is 44.5345% of actual value for residential property; 59.4401% of actual value for agricultural property and 100.0000% of the actual value of utility property. The residential taxable rollback rate of 44.5345% would apply to the value of each property unit of commercial, industrial and railroad property that exceeds zero dollars ($0), but does not exceed one hundred fifty thousand dollars ($150,000) with a taxable value rollback rate of 90.0000% to the value that exceeds one hundred fifty thousand dollars ($150,000). No adjustment was ordered for utility property because its assessed value did not increase enough to qualify for reduction. Utility property is limited to an 8% annual growth. The Legislature’s intent has been to limit the growth of statewide taxable valuations for the specific classes of property to 3% annually. Political subdivisions whose taxable values are thus reduced or are unusually low in growth are allowed to appeal the valuations to the State Appeal Board, in order to continue to fund present services. See “PROPERTY TAX LEGISLATION” herein for a discussion on recent legislative revisions to the administration of certain property taxes in Iowa.

LARGER TAXPAYERS Set forth in the following table are the persons or entities which represent larger taxpayers within the boundaries of the City, as provided by the Story County Auditor’s office. No independent investigation has been made of and no representation is made herein as to the financial condition of any of the taxpayers listed below or that such taxpayers will continue to maintain their status as major taxpayers in the City. With the exception of the electric and natural gas provider noted below (which is subject to an excise tax in accordance with Iowa Code chapter 437A), the City’s mill levy is uniformly applicable to all of the properties included in the table, and thus taxes expected to be received by the City from such taxpayers will be in proportion to the assessed valuations of the properties. The total tax bill for each of the properties is dependent upon the mill levies of the other taxing entities which overlap the properties.

If delinquent taxes are not paid, the property may be offered at the regular tax sale on the third Monday of June following the delinquency date. Purchasers at the tax sale must pay an amount equal to the taxes, special assessments, interest and penalties due on the property and funds so received are applied to taxes. A property owner may redeem from the regular tax sale but, failing redemption within three years, the tax sale purchaser is entitled to a deed, which in general conveys the title free and clear of all liens except future tax installments. 1) Source: The City’s Annual Comprehensive Financial Report for the Fiscal Year ended June 30, 2025. 2) Source: The City’s Adoption of Budget and Certification of City Taxes Form 85-811 for Fiscal Years 2025-26 and 2026-27. 44 A-7 TAX RATES FY 2021-22 $/$1,000 FY 2022-23 $/$1,000 FY 2023-24 $/$1,000 FY 2024-25 $/$1,000 FY 2025-26 $/$1,000 Story County 4.95627 4.50207 4.50196 4.41532 4.03184 Story County Hospital 0.87250 0.93350 0.93090 0.93090 0.99500 County Ag.

To control the growth of property taxes, the ACGFL is subject to potential limitation or reduction by constraining growth each year depending on if certain growth triggers are met or exceeded during the prior year. The levy limitation is only applicable Fiscal Year 2024-25 through Fiscal Year 2027-28. Beginning in Fiscal Year 2028-29, the levy limitation ceases and the City will go to a $8.10 ACGFL maximum. Certain levies like debt service, pensions, employee benefits and capital improvement reserve fund are not included in the new ACGFL limitation. The City’s recent property valuation growth has often exceeded the new legislative caps. Assuming the City exceeds the legislative caps in the future, the City’s general fund levies will lag its relative valuation growth. For Fiscal Year 2025-26, the City’s non TIF tax valuation growth was 2.60% causing no change to the City’s property tax revenue from the ACGFL. For Fiscal Year 2026-27, the City’s non TIF tax valuation growth was 5.86% causing the City’s property tax revenue from the ACGFL to be reduced by 2% of its revenues. The City’s Budget for Fiscal Year 2026-27 accommodated this mitigation of tax revenue relative to its non-TIF tax valuation growth. Debt service levies are not limited, rather the City is only subject to the aggregate constitutional debt limits. On May 18, 2026, the Governor signed into law Iowa Senate File 2472 (“SF 2472”), which enacts comprehensive reforms to Iowa's property tax system. SF 2472, among other things: (i) imposes growth-based caps limiting annual increases in property tax levy rates, generally restricting levy growth to 102% of the prior year's certified property tax dollars exclusive of New Valuation; (ii) restricts unassigned general fund reserves of certain local governments to 35% of budgeted general fund expenditures; (iii) prohibits the issuance of bonds or other indebtedness payable from ad valorem property taxes to fund general governmental operations; (iv) limits new urban renewal revenue division ordinances to a 23-year duration and imposes a 60% cap on tax increment captures from existing unlimited-duration urban renewal areas after 20 years; and (v) restructures the homestead credit program, replacing the existing credit with a new exemption of 10% of taxable value per eligible homestead (minimum $5,500, maximum $20,000, indexed for inflation). SF 2472 takes effect in part immediately upon enactment, with the majority of provisions applicable to fiscal years beginning on or after July 1, 2027.
