The District’s Finance Department prepared this report. The District is responsible for the accuracy of the data and the completeness and fairness of the presentation of the financial statements and other information presented herein. We believe the presentation is accurate in all material respects and includes all disclosures necessary to enable the reader to gain a reasonable understanding of the District’s financial activities. In the ACFR, the District’s financial activities are measured on a single enterprise fund basis where all funds of the District and its sub-districts are consolidated. The District’s ACFR includes an Introductory Section, a Financial Section, and a Statistical Section. The Introductory Section includes this transmittal letter, an organization chart as of June 30, 2023, which lists the District’s Board of Trustees, Rate Commission Chair, members of the Civil Service Commission, and management staff and the Government Finance Officers Association’s Certificate of Achievement For Excellence In Financial Reporting presented to the District for its Annual Comprehensive Financial Report for the fiscal year ended June 30, 2022. The Financial Section includes the independent auditors’ report, management’s discussion and analysis, the District’s basic financial statements and required supplementary information. The Statistical Section includes financial, economic, and demographic information, generally presented on a multi-year basis. The ACFR includes all funds of the District. The operations of these funds, as reflected in the financial statements, are under the control of the District’s governing body. The District has determined there were no other agencies or entities that met the established criteria for inclusion in the reporting entity. Separate from the District’s enterprise financial statements, the District’s fiduciary component unit’s financial statements for The Metropolitan St. Louis Sewer District Employees’ Pension Plan are also included in the ACFR. Metropolitan St. Louis Sewer District 2350 Market Street St. Louis, MO 63103-2555 314-768-6200 www.msdprojectclear.org The Board of Trustees The Metropolitan St. Louis Sewer District ii Organization MSD was created in 1954 to provide a metropolitan-wide sewer system to serve the City of St. Louis and most of the more heavily populated areas of St. Louis County. Before MSD’s creation, the City of St. Louis, various municipalities, and private sewer companies provided sewer service that primarily included only collecting and transporting sewage from small geographic areas to nearby rivers and streams with little or no treatment. Most of the municipalities or private sewer companies serving the area did not have the jurisdictional authority or financial resources needed to eliminate health hazards from untreated sewage. When the District began operations, it took over the publicly owned wastewater and stormwater drainage facilities within its jurisdiction and began the construction of an extensive system of collector and interceptor sewers and treatment facilities. In 1977, voters approved the District’s annexation of a 270 square mile area of the lower Missouri River and lower Meramec River watersheds. The District purchased the Fee Trunk Sewer Company and the Missouri Bottoms Sewer Company in 1978. MSD has since acquired other investor-owned or municipally operated systems. The District’s service area now encompasses 520 square miles including all 66 square miles of the City of St. Louis and 454 square miles of St. Louis County. The current population served by the District is approximately 1.3 million representing approximately 429,600 accounts. MSD is organized pursuant to Article VI, Section 30 of the Missouri State Constitution that empowers the people of St. Louis County and the City of St. Louis “to establish a metropolitan district for functional administration of services common to the area.” MSD is the only district established pursuant to that section of the Missouri State Constitution. The Charter of MSD (“Plan”), approved by voters in 1954 and amended in 2000, 2012 and 2021, established the District. The Plan describes the District as “a body corporate, a municipal corporation, and a political subdivision of the state.” As a political subdivision of the state, MSD is comparable to a county or city, such as St. Louis County or the City of St. Louis. The Plan established the governing body of the District as a six-member Board of Trustees (“Board”) with three members appointed by the Mayor of St. Louis and three members appointed by the St. Louis County Executive. Each Trustee shall be appointed for a term of four years. No Trustee shall serve more than two full consecutive terms plus any portion of an unexpired term; provided, however, that each Trustee shall serve until his/her successor shall be appointed and qualified. No more than two trustees appointed from the City or County shall be a member of the same political party. The Board of Trustees The Metropolitan St. Louis Sewer District iii Unlike a corporation’s board of directors that is responsible solely to the stockholders who choose to invest in the corporation, MSD’s Board members are trustees of public property and public funds. They are responsible to all citizens within the District. According to the Plan, the Board enacts District ordinances, determines policies, and appoints the Executive Director, the Secretary-Treasurer, and the Internal Auditor. The Executive Director appoints all other District officials. Among its duties, the Board makes all appropriations, approves contracts for improvements, and engages an accounting firm to perform the annual independent audit of the District. The Plan prescribes other duties of the Board and grants numerous broad powers, subject to federal and state laws, to the District and the Board of Trustees. Among other things, the Plan outlines the following requirements or provisions:  Requires that MSD operate with a balanced budget;  Details how MSD can tax property and requires an annual public hearing on all taxes levied by the District;  Details how MSD can establish user charges;  Requires MSD to establish civil service rules and regulations governed by a Civil Service Commission;  Provides how the original boundaries of the District may be extended to include any area in St. Louis County; and  Requires MSD to approve all plans and designs for proposed construction, alteration, or reconstruction of sewer or drainage facilities within the District’s boundaries. The District is also governed by the Missouri State Constitution and various federal and state laws that, among other requirements, mandate the following:  MSD must hold permits for all sanitary discharges. These permits require a minimum of secondary treatment;  MSD must provide wastewater treatment in an area-wide manner to qualify for federal and state grants;  MSD must operate, maintain, and replace facilities to provide proper wastewater treatment or be subject to penalties and fines; and  MSD must set user charge rates in compliance with the Federal Clean Water Act. These rates must be submitted to the Missouri Department of Natural Resources to receive future construction grants and to avoid the possibility of refunding past grants. During fiscal 2023 the primary source of funding for the operation and maintenance of MSD’s wastewater system was a user charge averaging $724.32 per year or $60.36 per month for a single-family residence. The District’s charges for residential wastewater The Board of Trustees The Metropolitan St. Louis Sewer District iv service are tied to the amount of measured water usage during a winter quarter. For residential properties without water meters, the charges are based on housing attributes (such as the number of rooms, baths, and toilets) that correlate to water usage. That methodology is the same billing methodology used by the City of St. Louis Water Division for their non-metered properties. Multi-family residential and non-residential rates are proportionate to the single-family charge and are based on water consumption and the strength of the discharge. During fiscal year 2023, the District’s revenue streams, particularly volume-based wastewater charges related to commercial customers, surpassed fiscal year 2021 which was impacted by COVID 19. Fiscal year 2023 volume- based billing units measured in ccf’s (one hundred cubic feet of water) were approximately 4.9% more than the ccf’s billed at the end of the District’s fiscal year 2021. In fiscal year 2023, volume-based billing units were 3.8% higher than fiscal year 2022 levels. During fiscal 2023 the District’s stormwater system was funded through property taxes of 1.7¢ per one hundred dollars assessed valuation for stormwater regulatory activities and 9.0¢ per one hundred dollars assessed valuation for operations and maintenance of the District’s stormwater utility. The District also performs limited capital improvements with the revenues generated by the 9.0¢ tax. Prior to fiscal year 2017, the operation and maintenance of the District’s stormwater system was funded by a combination of property taxes and a flat fee billing of 24¢ per month for residential and commercial properties and 18¢ per month per unit for multi- unit properties. On April 5, 2016, over 62% of voters in MSD’s service area approved Proposition S which placed all MSD customers under the same property tax rates to fund stormwater services. The flat fee billings were eliminated. MSD also receives some federal, state, and local grants to help defray the cost of constructing sewage treatment and drainage facilities and improvements. The District also charges fees for plan review, permits, construction inspection of new system development, and special discharges. The District charges a uniform connection fee in all service areas. The District, itself, may issue general obligation bonds and revenue bonds to finance the cost of improvements and extensions to the sewer system. The District also may issue, on behalf of each of its subdistricts, general obligation bonds, revenue bonds, or special assessment bonds. Major Initiatives Affecting the Financial Resources of the District There were once hundreds of points in MSD’s service area where a combination of stormwater and wastewater discharged into local waterways from the wastewater sewer system during moderate to heavy rainstorms. These sewer overflow points act as relief valves when too much stormwater enters the wastewater system, and without them, our The Board of Trustees The Metropolitan St. Louis Sewer District v community could experience thousands of basement backups and/or extensive street flooding. Even with these overflow points, basement backups can easily number in the dozens or hundreds during particularly heavy rains. Depending on where sewer overflows are located within MSD’s system, they are classified as combined sewer overflows or constructed separate sewer overflows. Many of these overflows are a legacy of the way our wastewater systems were first built. Though most overflows predate the District’s creation in 1954, they are still MSD’s responsibility and efforts to address the problem must continue. Sewer overflows have been a significant focus of MSD’s work for many years. From 1992 to 2012, MSD spent approximately $2.7 billion to eliminate over 380 overflows. Today, our work to address sewer overflows and improve water quality continues through a Consent Decree that stems from a lawsuit filed against MSD by the State of Missouri and the United States Environmental Protection Agency (“EPA”) in June 2007. The State of Missouri and the EPA were later joined in the lawsuit by the Missouri Coalition for the Environment. After lengthy mediation, the EPA announced a settlement agreement in August 2011. On April 27, 2012, the United States District Court for The Eastern District of Missouri entered a Consent Decree, thus concluding the litigation. The Consent Decree calls for more than $7 billion in upgrades to the existing wastewater sewer system (in 2023 dollars). Also known as MSD Project Clear, this work was originally scheduled to take place over 23 years and addresses our community’s wastewater collection and treatment capabilities on a system-wide basis. However, on June 22, 2018, a United States District judge approved an amendment to the Consent Decree that extends the schedule from 23 years to 28 years. The motivation behind the amendment are regulatory changes that compel MSD to accelerate certain projects that do not fall within the scope of the Consent Decree. The time extension will allow MSD to address new regulatory requirements, while minimizing the financial burden on customers. The work is a mammoth undertaking that will benefit St. Louisans – and our environment – for generations to come. MSD is just over 10 years into the project, a massive effort to upgrade the region’s aging wastewater system by separating areas with combined wastewater and stormwater pipes that lead to discharges of sewage into the Mississippi River and its tributaries. In the 11 years since the project commenced, MSD has accomplished the following:  Removed 85% (123 of 149) of constructed sanitary sewer overflows, where excess wastewater flows are discharged when the system is over capacity.  Spent $50.5 million out of a pledged $100 million on a Green Infrastructure Program, which has resulted in the removal of 53 million gallons of combined sewer overflow. The Board of Trustees The Metropolitan St. Louis Sewer District vi  Continued construction of Jefferson Barracks and Lower Meramec tunnels; continued planning of River Des Peres Tributaries CSO tunnel and final engineering of the Lower and Middle Des Peres storage tunnel.  Completed 247 system improvements, including the Maline Creek Tunnel, Deer Creek Tunnel, Gravois Creek Storage Tanks, and DC-02/DC-03 sanitary relief project.  Started construction on the Lower Meramec Wastewater Treatment Plant expansion phase I.  Continued planning of nutrient removal.  Negotiated amendment to 208 (Section 208 of the Clean Water Act) plan to save customers approximately $200 million. In fiscal year 2022, MSD proposed a modification to the Upper River Des Peres Storage Tunnel and River Des Peres Tributaries Storage Tunnel to replace them with a single storage tunnel (Upper River Des Peres and River Des Peres Tributaries Storage Tunnel) to lessen traffic and reduce construction impacts in the Richmond Heights area. This community is already disproportionately affected by heavy traffic and pollution exposure. The revision also reduced the need for purchasing residential properties and easement acquisition, as well as allowed for easier access in and out of construction areas. The new single tunnel is anticipated to be fully operational by December 31, 2037. The modification to the Upper River Des Peres and River Des Peres Tributaries Storage Tunnel represents good engineering practice. The single tunnel limits the impact on nearby communities, further improves the environmental benefit, and allows MSD to maintain an acceptable financial burden for its ratepayers. The U.S. Environmental Protection Agency must approve the proposed modification. The Sewer District will continue their management activities. Operations The Executive Director and his staff administer the operation and maintenance of the District’s collection and treatment systems. The District’s wastewater, stormwater, and combined sewer collection system includes approximately 9,400 miles of pipe and channel and will grow larger over the long term due to new development. Some years may see a reduction in total miles of pipe. This is due to the replacement of inefficiently placed pipe with shorter, more direct lines of pipe. The District’s responsibilities for stormwater drainage range from cleaning and maintaining street inlets to operating and maintaining the floodwall pump stations along the Mississippi River. MSD currently operates seven wastewater treatment facilities. These facilities treated an average flow of 291.2 million gallons per day (“MGD”) in fiscal 2023 compared to 289.5 MGD in fiscal 2022. Fiscal year 2023 flows were consistent with fiscal year 2022 levels. The design capacity and average flow, by watershed, in MGD was as follows in fiscal The Board of Trustees The Metropolitan St. Louis Sewer District vii 2023: MAJOR WATERSHED LEVEL OF TREATMENT NUMBER OF FACILITIES DESIGN CAPACITY (MGD) AVERAGE FLOW FISCAL 2023 (MGD) Mississippi River Secondary Two 472.00 218.50 Missouri River Secondary Two 78.00 45.30 Meramec River Secondary Three 42.75 27.40 Total Seven 592.75 291.20 In addition to construction initiated by the District to protect the public’s health and property from raw sewage and flooding, the District also provides various engineering- related design review and inspection services for the construction of wastewater and stormwater sewers by individuals, businesses, and municipalities in the community. Economic Conditions In The St. Louis Metropolitan Area As a rule, the District’s major revenue sources do not fluctuate with the local and national economy as much as local governments that depend on sales or income taxes for their major sources of revenue. The combined unemployment rate for the City of St. Louis and St. Louis County was 3.4 percent in June 2023 and lower than the national unemployment rate of 3.6 percent for the same time period. The June 2023 unemployment rate of 3.4 percent is higher than the June 2022 rate of 2.5 percent. MSD has its own internal barometers for measuring economic development within the District. These are listed below for fiscal 2023 and 2022: 2023 2022 Sewer Plan Reviews: Number of Plans Approved 439 446 Number of Miles of Sewers 39 52 Sewer Construction Permits: Number of Permits Issued 2,506 2,125 Number of Miles of Sewers 19 18 Customer Connections: Number of Connection Permits Issued 2,506 1,919 Connection Fee Revenue (in millions) $1.3 $1.3 Value of Sewers Dedicated to MSD by Developers (in millions) $8.5 $13.3 Over the years, the St. Louis economy has undergone a transformation from reliance on traditional manufacturing industries to those industries based on advanced technology The Board of Trustees The Metropolitan St. Louis Sewer District viii and services. The St. Louis area is a center for health care, biotechnology, banking, finance, transportation, tourism, and education and has a strong and diverse manufacturing economy. The area has an abundance of energy, water, and sewerage facilities and can sustain future economic growth. Financial Information Proprietary Operations. The current financial condition of MSD remains stable. The District realized a net operating income of $152.6 million in fiscal 2023 compared to a restated net operating income of $160.4 million in the prior year. Fiscal year 2022 operating expenses were restated due to the implementation of GASB 96 which resulted in a decrease in operating expenses of $0.8 million. Operating revenues increased by $13.5 million from fiscal 2022 due to growth in sewer service charges but this increase was offset by an increase in operating expense of $21.3 million. The increase in operating expenses was driven by a $14.4 million increase in general and administrative expenses which consisted of a $4.2 decrease of the FY 2022 reported amount due to the aforementioned restatement and a $13.1 million increase in Governmental Accounting Standards Board (GASB) Statement No. 68 related pension. Operating expenses were also impacted by an increase in water backup claims of $5.7 million. A more in-depth analysis of the District’s financial position and the magnitude of the capital improvement and replacement program (“CIRP”) is provided in the Management’s Discussion and Analysis section that appears later in this report. Budgetary Controls. The District’s Plan requires MSD to submit a proposed budget to the Board by March 15th each year. After Board review, a final budget is approved in June. The District’s Plan also requires MSD to maintain budgetary controls and to adopt a balanced budget. The objective of these budgetary controls is to ensure compliance with legal provisions embodied in the appropriation process approved by the Board. The annual appropriated budget includes activities of the District’s operating and debt service funds. The Board adopts ordinances to appropriate funds for capital improvement expenditures at the time of the contract award and acceptance of any grant offers. Budgetary control is by Division and major expenditure category within the General Fund, each Debt Service Fund, and each capital improvement contract. The District utilizes an encumbrance accounting system in conjunction with internal variance and projection analysis to maintain budgetary control. Certain encumbrances carry over from one year to the next as approved by the Board during the budget process. Monthly and year-end financial reports are prepared in accordance with United States generally accepted accounting principles for Enterprise Funds. Adjustments are made to the accounting records, where necessary, to reflect the full accrual method of accounting. Under the full accrual method of accounting, revenues are recognized when earned and expenses are recorded as liabilities when incurred. Encumbrances and unearned capital The Board of Trustees The Metropolitan St. Louis Sewer District ix and operating grants are eliminated under the full accrual method of accounting. These amounts are disclosed as commitments in the notes to financial statements. Cash Management. In compliance with its Plan, the District invests temporarily idle funds in cash, cash equivalents and investments such as collateralized certificates of deposit, collateralized repurchase agreements, obligations of any agency of the United States, and United States Treasury instruments. The District utilizes competitive bidding for investment purchases and monitors market conditions daily. Risk Management. In-house staff and consultants jointly conduct risk management activities. MSD maintains third-party commercial insurance coverage for various risks while self-insuring for other risks and liabilities at levels customary for similar enterprises. The District maintains a replacement cost property and casualty primary insurance policy with a limit of $1.0 billion per occurrence on certain facilities and equipment. The District maintains three excess liability insurance policies relating to facilities and equipment that each have $5.0 million per occurrence/aggregate limits. The District assumes the risk of loss (including payment of water backup claims to its customers) on most of its underground pumping facilities and collection system. MSD is one of the few sewer districts in the country known to provide water backup claim coverage to its customers. To minimize exposure to loss, the District inspects its facilities regularly and performs preventative maintenance on them. The District is self-insured for workers’ compensation and funds those costs through annual appropriations from the District’s general insurance fund. The District maintains reinsurance for workers’ compensation liabilities in excess of specified limits up to the statutory limit. Risk control activities include using a third-party claims administrator, maintaining a computerized claim tracking system, and annually reevaluating workers’ compensation cost. The District also has programs designed to promote safety in the workplace and employee wellness. The District provides group medical coverage for its employees and offers dependent medical coverage on a contributory basis through a self-insured plan. Effective February 1, 2014, the District maintained stop loss coverage for specific claims exceeding $175,000 per year and for total annual claims greater than 125 percent of the annual claims estimate. The District provides its employees with contributory group dental insurance coverage and non-contributory life insurance and contributory optional life insurance coverage. The District also contributes $125 every fiscal year, up to a maximum of $500, to a vision care program for employees. Effective July 1, 2013, spouses were eligible to use the benefits; effective July 1, 2016, dependent children up to age 26 were eligible to use the benefits; however, the amount could not exceed the maximum amount of $500. The District reevaluates insurance coverage and providers annually by reevaluating medical insurance claims and health benefit costs. The Board of Trustees The Metropolitan St. Louis Sewer District x For most construction projects, insurance is obtained by the individual contractor and included in the contract price. Internal Controls. District Management is responsible for designing, establishing, and maintaining an internal control system that protects District assets from loss, theft, or misuse and ensures that adequate accounting data is compiled to prepare financial statements in conformity with United States generally accepted accounting principles. Internal control systems are designed to provide reasonable, but not absolute, assurance that these objectives are met. The concept of reasonable assurance recognizes that the cost of a control should not exceed the benefits likely to be derived and that the evaluation of costs and benefits requires estimates and judgments by management. The District’s internal control system is subject to periodic evaluation by Management, the Board and the District’s independent accountants. Other Information Audit Requirements. The District’s Plan requires an annual audit by independent certified public accountants. The District’s ACFR includes a report on the District’s financial statements by the accounting firm of CliftonLarsonAllen LLP. Besides meeting the requirements set forth in the Plan, the annual audit is also designed to meet the requirements of the 2013 Uniform Administrative Requirements, Cost Principles, and Audit Requirements for Federal Awards (“Uniform Guidance”) that was issued by the Office of Management and Budget (“OMB”). A Single Audit Report will be issued for the year ended June 30, 2023. The financial statements of The Metropolitan St. Louis Sewer District Employees’ Pension Plan, The Metropolitan St. Louis Sewer District Deferred Compensation Plan and Trust and The Metropolitan St. Louis Sewer District Defined Contribution Plan are also audited annually. These audit reports were issued for the periods ending December 31, 2022, and 2021 and are available to interested parties upon request. Awards. The Government Finance Officers Association of the United States and Canada (“GFOA”) awarded a Certificate of Achievement for Excellence in Financial Reporting to MSD for its ACFR for the fiscal year ended June 30, 2022. The Certificate of Achievement is a prestigious national award that recognizes conformance with the highest standards for preparation of state and local government financial reports. To be awarded the Certificate of Achievement, a government unit must publish an easily readable and efficiently organized ACFR, the contents of which conform to program standards. The ACFR must satisfy both U.S. generally accepted accounting principles and applicable legal requirements. A Certificate of Achievement is valid for one year only. The District has received a Certificate of Achievement for the last thirty-five consecutive The Board of Trustees The Metropolitan St. Louis Sewer District xi years. We believe the current ACFR continues to conform to the GFOA’s high standards, as reflected in the Certificate of Achievement program requirements, and are submitting it again this year for consideration. The District also received the GFOA’s Distinguished Budget Presentation award for its fiscal 2023 annual budget. The District has received this award for thirty-six consecutive years. We believe the fiscal year 2024 budget presentation continues to meet the GFOA’s high standards and have submitted it for consideration. The District also received the GFOA’s Award for Outstanding Achievement in Popular Annual Financial Reporting (“PAFR”) for its fiscal year 2022 PAFR. We have received this award for every year since the publication of our first PAFR for fiscal year 2012 and intend to submit the fiscal year 2023 PAFR for consideration. Marion M.

LOUIS SEWER DISTRICT SERVICE AREAS 1 INDEPENDENT AUDITORS’ REPORT Board of Trustees The Metropolitan St. Louis Sewer District St. Louis, Missouri Report on the Audit of the Financial Statements Opinions We have audited the accompanying financial statements of the business-type activities and the fiduciary activities of The Metropolitan St. Louis Sewer District (the District), as of and for the years ended June 30, 2023 and 2022 (except for the fiduciary activities, which is as of and for the years ended December 31, 2022 and 2021), and the related notes to the financial statements, which collectively comprise the District’s basic financial statements as listed in the table of contents. In our opinion, the financial statements referred to above present fairly, in all material respects, the respective financial position of the business-type activities and the fiduciary activities of The Metropolitan St. Louis Sewer District, as of June 30, 2023 and 2022 (except for the fiduciary activities, which is as of and for the years ended December 31, 2022 and 2021), and the respective changes in financial position, and, where applicable, cash flows thereof for the years then ended in accordance with accounting principles generally accepted in the United States of America. Basis for Opinions We conducted our audits in accordance with auditing standards generally accepted in the United States of America (GAAS) and the standards applicable to financial audits contained in Government Auditing Standards, issued by the Comptroller General of the United States. Our responsibilities under those standards are further described in the Auditors’ Responsibilities for the Audit of the Financial Statements section of our report. We are required to be independent of the District and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements relating to our audit. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinions. Emphasis of Matter As disclosed in Note 1, the District implemented the provisions of Governmental Accounting Standards Board Statement No. 96 – Subscription-Based Information Technology Arrangements. The Standard establishes that a subscription-based information technology arrangement results in a right-to-use subscription asset and a corresponding subscription liability. Our opinions are not modified with respect to this matter. Responsibilities of Management for the Financial Statements Management is responsible for the preparation and fair presentation of the financial statements in accordance with accounting principles generally accepted in the United States of America, and for the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error. CLA (CliftonLarsonAllen LLP) is an independent network member of CLA Global. See CLAglobal.com/disclaimer.  CliftonLarsonAllen LLP  CLAconnect.com  Board of Trustees The Metropolitan St. Louis Sewer District 2 In preparing the financial statements, management is required to evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about the District’s ability to continue as a going concern for twelve months beyond the financial statement date, including any currently known information that may raise substantial doubt shortly thereafter. Auditors’ Responsibilities for the Audit of the Financial Statements Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinions. Reasonable assurance is a high level of assurance but is not absolute assurance and therefore is not a guarantee that an audit conducted in accordance with GAAS and Government Auditing Standards will always detect a material misstatement when it exists. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control. Misstatements are considered material if there is a substantial likelihood that, individually or in the aggregate, they would influence the judgment made by a reasonable user based on the financial statements. In performing an audit in accordance with GAAS and Government Auditing Standards, we: Exercise professional judgment and maintain professional skepticism throughout the audit. Identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, and design and perform audit procedures responsive to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the District’s internal control. Accordingly, no such opinion is expressed. Evaluate the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluate the overall presentation of the financial statements. Conclude whether, in our judgment, there are conditions or events, considered in the aggregate, that raise substantial doubt about the District’s ability to continue as a going concern for a reasonable period of time. We are required to communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit, significant audit findings, and certain internal control related matters that we identified during the audit. Board of Trustees The Metropolitan St. Louis Sewer District 3 Required Supplementary Information Accounting principles generally accepted in the United States of America require that the management’s discussion and analysis, schedule of changes in net pension liability and related ratios for the employees’ pension plan, schedule of employer contributions to employees’ pension plan and schedule of changes in total OPEB liability be presented to supplement the basic financial statements. Such information is the responsibility of management and, although not a part of the basic financial statements, is required by the Governmental Accounting Standards Board who considers it to be an essential part of financial reporting for placing the basic financial statements in an appropriate operational, economic, or historical context. We have applied certain limited procedures to the required supplementary information in accordance with GAAS, which consisted of inquiries of management about the methods of preparing the information and comparing the information for consistency with management’s responses to our inquiries, the basic financial statements, and other knowledge we obtained during our audit of the basic financial statements. We do not express an opinion or provide any assurance on the information because the limited procedures do not provide us with sufficient evidence to express an opinion or provide any assurance. Other Information Management is responsible for the other information included in the annual report. The other information comprises the introductory and statistical sections but does not include the basic financial statements and our auditors’ report thereon. Our opinions on the basic financial statements do not cover the other information, and we do not express an opinion or any form of assurance thereon. In connection with our audit of the basic financial statements, our responsibility is to read the other information and consider whether a material inconsistency exists between the other information and the basic financial statements, or the other information otherwise appears to be materially misstated. If, based on the work performed, we conclude that an uncorrected material misstatement of the other information exists, we are required to describe it in our report. Other Reporting Required by Government Auditing Standards In accordance with Government Auditing Standards, we have also issued our report dated December 4, 2023, on our consideration of The Metropolitan St. Louis Sewer District’s internal control over financial reporting and on our tests of its compliance with certain provisions of laws, regulations, contracts, and grant agreements and other matters. The purpose of that report is solely to describe the scope of our testing of internal control over financial reporting and compliance and the results of that testing, and not to provide an opinion on the effectiveness of The Metropolitan St. Louis Sewer District’s internal control over financial reporting or on compliance. That report is an integral part of an audit performed in accordance with Government Auditing Standards in considering Metropolitan St. Louis Sewer District’s internal control over financial reporting and compliance. CliftonLarsonAllen LLP St. Louis, Missouri December 4, 2023 THE METROPOLITAN ST. LOUIS SEWER DISTRICT Page 4 MANAGEMENT’S DISCUSSION AND ANALYSIS For the Years Ended June 30, 2023 and 2022 The annual report of The Metropolitan St. Louis Sewer District (“MSD” or the “District”) includes the independent auditors’ report, management’s discussion and analysis (“MD&A”), and the financial statements accompanied by notes essential to the user’s understanding of the financial statements. Management of the District has provided this MD&A to be used in combination with the District’s financial statements. This narrative is intended to provide the reader with more insight into management’s knowledge of the transactions, events, and conditions reflected in the accompanying financial statements and the fiscal policies that govern the District’s operations. 2023 Financial Highlights The District increased net capital assets by $230.3 million as a result of increases in construction in progress ($203.9 million), depreciable capital assets net of depreciation ($25.0 million) and land ($1.4 million). The District placed $131.7 million of capital assets into service during fiscal year 2023. The continued high level of capitalization reflects the District’s work to meet long-term plans. Capitalized assets included: Collection and pumping plant $105.0 million Subscription-based IT agreements $15.6 million General plant and equipment $7.0 million Treatment and disposal plant and equipment $2.4 million Land $1.6 million Lease Assets $0.1 million The net increase to accumulated depreciation and amortization was $99.2 million which takes into consideration the recording of depreciation and amortization relating to new assets in addition to depreciation and amortization on existing assets offset by the accumulated depreciation and amortization relieved for assets retired during the year. During the 2023 fiscal year the District implemented one Governmental Accounting Standards Board (“GASB”) Statement, GASB 96. See Note 1, Summary of Significant Accounting Policies, in the accompanying notes to the financial statements for more detailed information. 2022 Financial Highlights The District increased net capital assets by $187.1 million as a result of increases in land ($2.6 million) and depreciable capital assets net of depreciation ($199.6 million) offset by a decrease in construction in progress ($15.1 million). THE METROPOLITAN ST. LOUIS SEWER DISTRICT Management’s Discussion And Analysis (Continued) Page 5 The District placed $305.3 million of capital assets into service during fiscal year 2022. The continued high level of capitalization reflects the District’s work to meet long-term plans. Capitalized assets included: Collection and pumping plant $238.8 million Treatment and disposal plant and equipment $29.2 million Subscription-based IT agreements $26.7 million General plant and equipment $7.5 million Land $2.6 million Lease Assets $0.5 million The net increase to accumulated depreciation and amortization was $98.9 million which takes into consideration the recording of depreciation and amortization relating to new assets in addition to depreciation and amortization on existing assets offset by the accumulated depreciation and amortization relieved for assets retired during the year. During the 2022 fiscal year the District implemented two Governmental Accounting Standards Board (“GASB”) Statements. See Note 1, Summary of Significant Accounting Policies, in the accompanying notes to the financial statements for more detailed information. Required Financial Statements The basic financial statements presented by the management of the District include the Statements of Net Position; Statements of Revenues, Expenses, and Changes in Net Position; Statements of Cash Flows; Statements of Fiduciary Net Position; and Statements of Changes in Fiduciary Net Position. These statements are prepared using the accrual basis of accounting in conformity with generally accepted accounting principles in the United States of America as applied to government units. This method of accounting recognizes revenue at the time it is earned and expenses when the related liability occurs. As a result of using this method of accounting, the District’s performance over the time period being reported is more easily determinable. The District’s basic financial statements also include the Notes to the Financial Statements and Required Supplementary Information. In addition, certain statistical supplementary information is presented for additional analysis but is not a required part of the basic financial statements. The Statements of Net Position provide a report of the District’s current, restricted, and other non-current assets such as cash, investments, receivables, and capital assets. Also, the Statements of Net Position provide a summary of the District’s current, restricted, and non-current liabilities, including contracts and accounts payable, deposits and accrued expenses, pension and OPEB liabilities and bonds and notes payable. Deferred outflows and inflows of resources, where applicable, are also included. The final section of the Statements of Net Position, the net position section, contains earnings retained for THE METROPOLITAN ST. LOUIS SEWER DISTRICT Management’s Discussion And Analysis (Continued) Page 6 use by the District. Increases or decreases in the net position section may be indicative of an improving or declining financial position. This statement provides the basis for computing rate of return, evaluating the capital structure of the District, and assessing the liquidity and financial flexibility of the District. The Statements of Revenues, Expenses, and Changes in Net Position summarize the years’ revenues and expenses. These statements indicate how successful the District was at maintaining expenses below the level of revenue earned. The Statements of Cash Flows account for the net change in cash and cash equivalents by summarizing cash receipts and cash disbursements resulting from operating activities, non-capital financing activities, capital, and related financing activities, and investing activities. These statements assist the user in determining the sources of cash coming into the District, the items for which cash was expended, and the beginning and ending cash balances. The Notes to the Financial Statements provide additional information that is essential to obtain a full understanding of the data provided in the basic financial statements, such as the District’s significant accounting policies, investment instruments, outstanding debt, employee benefit plans, segment information and subsequent events to name a few. The Required Supplementary Information section provides detail in support of the changes in the net pension liability and the total other postemployment benefits (“OPEB”) liability and information pertaining to the District’s actuarially determined contributions to the Pension Plan. The Statistical Section provides significant data that afford the reader a better historical perspective and assist in assessing the current financial status and trends of the District for which ten years of data is generally provided. Financial Analysis The District’s financial position improved in the current year, as evidenced by the increase in net position of $147.7 million. The improvement is due primarily to an increase in net investment in capital assets and subdistrict construction and improvement funds, of $158.0 million, $11.3 million respectively; offset by a decrease in unrestricted funds and debt service funds of $21.1 million and $0.5 million, respectively. The increase in net investment in capital assets net position is comprised of a $230.3 million increase in net capital assets and $56.8 million decrease in debt related to capital assets; offset by decrease of $112.8 million in unspent bond proceeds, $15.3 million in construction-related liabilities, $0.8 million increase in deferred gain on debt refunding, and the $0.2 million amortization of deferred losses. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Management’s Discussion And Analysis (Continued) Page 7 Condensed Financial Statements and Analysis 2023 Analysis Current, non-current, restricted, and other assets decreased $107.7 million or 12.2% in the current year. The decrease is predominately due to a decrease in cash and long-term investments due to decrease in issuance of bonds. Capital assets net of accumulated depreciation and amortization increased by $230.3 million or 5.4% in the current year as the result of continued high levels of construction and acquisition of assets by the District. Current liabilities increased by $25.6 million or 14.9% due primarily to an increase in contracts and accounts payable, current portion of bonds and notes payable, and retainage held on capital projects.

LOUIS SEWER DISTRICT Management’s Discussion And Analysis (Continued) Page 8 Non-current liabilities increased by $0.6 million or 0.03% primarily due to net increases in net pension liability of $63.4 million; offset by the net decrease in bonds and notes payable, lease and subscription liability and OPEB liability of $60.4 million, $1.6 million and $0.7 million, respectively. The net decrease in bonds and notes payable is primarily related to the $56.3 million in senior and subordinate debt reclassified to current liabilities and the net decrease of $4.0 million in amortization premiums received. Net deferred outflows and inflows increased $51.3 million or 327.5% due primarily to updates to various information provided by the District’s actuary such as economic/demographic gains or losses, assumption changes or inputs, and investment gains or losses related to the District’s net pension liability or total OPEB liability. 2022 Analysis Current, non-current, restricted, and other assets increased $48.4 million or 5.8% in the current year. The increase is predominately due to an increase in cash and long-term investments due to increased unspent bond proceeds and more taxes levied and collected. Capital assets net of accumulated depreciation and amortization increased by $187.1 million or 4.6% in the current year as the result of continued high levels of construction and acquisition of assets by the District. Current liabilities increased by $6.1 million or 3.7% due primarily to an increase in contracts and accounts payable and retainage held on capital projects, offset by an increase in current portion of bond and notes payable. Non-current liabilities increased by $91.2 million or 5.0% primarily due to net increases in bonds and notes payable, net pension liability and total OPEB liability of $70.4 million, $4.4 million, and $1.9 million, respectively. The net increase in bonds and notes payable is related to the $197.3 million new senior and direct placement debt issued in fiscal year 2022 and a net increase of $21.9 million in premiums received in fiscal 2022 on debt issuances offset by $66.3 million for fiscal 2022 senior and subordinate debt payments reclassified to current liabilities, $28.4 million current refunding of existing debt, and $1.6 million amortization of premiums, net of discount. Net deferred outflows and inflows decreased $2.0 million or 14.8% due primarily to updates to various information provided by the District’s actuary such as economic/demographic gains or losses, assumption changes or inputs, and investment gains or losses related to the District’s net pension liability or total OPEB liability.

The largest impacts to net position were the increase in investment income and the increase in sewer service charge revenue. Total revenue increased by $42.9 million or 8.7% resulting primarily from the increase in investment income and sewer service charges. Other operating revenue decreased $3.9 million or 58.0% primarily due to a reduction of liquidated damages and forfeited deposits. Property taxes increased $4.2 million or 9.6% due primarily to higher property valuation assessments. Investment income increased $25.2 million or 201.2% primarily due to a $15.1 million unrealized gain on investments recorded in fiscal 2023 versus a $12.3 million loss in unrealized loss in fiscal 2022. Total expenses increased by $25.5 million or 6.9% resulting primarily from the increase in operating expenses and non-recurring projects and studies. Operating expenses increased $21.2 million or 7.1% with increases in general and administrative, water back up claims, pumping and treatment, collection system maintenance, amortization, and depreciation of $14.2 million, $5.7 million, $2.0 million, $1.7 million, $1.2 million and $0.8 million, respectively; offset by decreases in asset management of $4.3 million and engineering of $0.1 million. General and administrative increased $14.2 million primarily due to an increase in pension expense based on an actuarial study. Non-operating expenses increased $4.3 million or 6.0% due primarily to increases in non-recurring projects and studies. Capital grants and contributions decreased $6.0 million or 39.1% with the majority of the decrease resulting from capital contributions as the value of capital projects contributed to the District decreased in fiscal 2023. 2022 Analysis Net position increased $136.2 million or 4.7% over the prior year which was an $8.8 million or 6.9% increase from last year’s net position increase.

Cash flows from operating activities decreased by $6.5 million or 2.8% is primarily due to an increased payments to suppliers of $22.6 million; offset by increased receipts from customers of $17.1 million. Cash flows from non-capital financing activities increased by $3.4 million or 7.8% due to higher taxes receipts. Cash flows from capital and related financing activities decreased by $181.6 million or 81.2% due primarily to a $140.4 million decrease in bond proceeds from issuance of debt received in fiscal year 2023 compared to fiscal year 2022, $37.0 million increase in spending for capital assets, $3.1 million increase in principal, interest and fees paid on bonds due and $0.6 million decrease in capital grant proceeds. Cash flows from investing activities increased by $87.2 million or 194.5%. The increase primarily stems from the fact that the difference between investments maturing increased $217.2 million while investments purchased increased by $132.8 million in fiscal 2023 compared to fiscal year 2022. 2022 Analysis The District ended the year with $134.5 million in cash and cash equivalents for an increase of $12.2 million or 10.0% from the prior year.

Decisions Impacting the Future Integral to helping MSD’s rate payers understand the District’s Consent Decree (“CD”) with the U.S. Environmental Protection Agency, the State of Missouri, and the Missouri Coalition for the Environment, which settled a lawsuit for alleged violations of the Clean Water Act, was the initiation of MSD Project Clear. See Note 15, Commitments and Contingencies, for additional information regarding this litigation. The goal of MSD Project Clear is to help MSD’s rate payers have a clear understanding of MSD’s goals and objectives. MSD Project Clear consists of three main components: Getting the Rain Out which is focused on reducing excess stormwater from entering the sewer system infrastructure to help reduce basement back-ups and overflows; THE METROPOLITAN ST. LOUIS SEWER DISTRICT Management’s Discussion And Analysis (Continued) Page 17 Performing Repair and Maintenance to the existing infrastructure to ensure it operates as well as possible for as long as possible; and Building System Improvements where needed to increase the capacity of the system. MSD Project Clear will greatly affect the daily lives of many of our rate payers and is needed to help the rate payer understand the individual and regional, as well as the immediate and long-term, benefits of the program. Since February 2004, the voters in the District’s service area have authorized the District to issue a total of $3.1 billion in wastewater revenue bonds. As of June 30, 2023, the District has issued $2.5 billion of the total authorization. The District’s long-term wastewater capital improvement program will continue to be funded through a combination of additional bonds and wastewater rate increases.

LOUIS SEWER DISTRICT Page 25 NOTES TO FINANCIAL STATEMENTS June 30, 2023 AND 2022 1. Summary of Significant Accounting Policies Organization The Metropolitan St. Louis Sewer District (“District”) was authorized by the voters, established and chartered under Article VI, Section 30 of the Constitution of Missouri as a municipal corporation and a political subdivision of the State of Missouri. Upon creation in 1954, the District assumed responsibilities to provide for the construction, operation, and maintenance of the sewer facilities within its defined boundaries. The District’s service area now comprises all of the City of St. Louis and most of St. Louis County. Subdistricts within the District’s total service area represent separate geographic areas within which specific taxes can be levied to operate and maintain wastewater or stormwater facilities within the area or construct improvements within the subdistrict. The District also maintains all of the publicly owned stormwater sewers within its original boundaries and is continuing to accept maintenance of the stormwater sewers in the remainder of its service area. Pursuant to provisions of its Charter and subject to limitations imposed by the Constitution of Missouri, all powers of the District are vested in a six-member Board of Trustees (“Board”), three of whom are appointed by the Mayor of the City of St. Louis and three of whom are appointed by the County Executive of St. Louis County. Not more than two Trustees appointed from said City or County, as the case may be, shall be a member of the same political party. Reporting Entity The District defines its financial reporting entity to include all component units for which the District’s governing body is financially accountable. To be considered financially accountable, the component unit must be fiscally dependent on the District and the District must either 1) be able to impose its will on the component unit or 2) the relationship must have the potential for creating a financial benefit or imposing a financial burden on the District. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 26 The District sponsors a single employer defined benefit pension plan and trust for which the District contributes the actuarially determined contribution each year. Pursuant to the adoption in fiscal year 2021 of Statement No. 84 of the Governmental Accounting Standards Board, Fiduciary Activities, it was determined that the defined benefit pension plan and trust qualifies as a fiduciary component unit that meets the criteria of a fiduciary activity and the Statements of Fiduciary Net Position and the Statements of Changes in Fiduciary Net Position for The Metropolitan St. Louis Sewer District Employees’ Pension Plan are presented following the District’s basic financial statements. The District issues a publicly available report for the defined benefit pension plan and trust with audited financial statements that is available upon request and is also available on the District’s msdprojectclear.org website. While included in the separately issued report, the Cash and Investments and the Fair Value Measurement and Application note disclosures for the fiduciary activity are presented herein as Notes 9 and 10. Based on the foregoing, the District’s financial statements include all funds that are established under the authority of the District’s charter. There are no agencies, boards, commissions, or authorities that are controlled by or dependent on the District. Measurement Focus, Basis of Accounting and Financial Statement Presentation The Governmental Accounting Standards Board (“GASB”) is the accepted standard-setting body for establishing accounting and financial reporting standards for U.S. state and local governments that follow generally accepted accounting principles (“GAAP”). As a political subdivision of the State of Missouri, the District follows GASB Pronouncements. Throughout the year, the District maintains its detailed accounting records on a modified accrual basis of accounting. In order to account for the transactions related to certain subdistricts and restricted resources, separate fund accounting records are maintained. For financial reporting purposes, the District reports its operations as a single enterprise fund and the financial statements are prepared in conformity with accounting principles generally accepted in the United States of America as applied to government units. Accordingly, the accounting records are converted to the accrual basis of accounting and all interfund transactions are eliminated. The District’s fiduciary financial statements are also presented in conformity with accounting principles generally accepted in the United States of America on an accrual basis of accounting. Under the accrual basis of accounting, revenues are recognized when earned and expenses are recognized when the related liability is incurred. The District’s measurement focus for both the basic THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 27 financial statements and the financial statements of the District’s fiduciary activity is on the flow of economic resources. Revenues and expenses are divided into operating and non-operating items. Operating revenues generally result from providing services in connection with the District’s principal ongoing operations. The principal operating revenues of the District are user fees, licenses, and permits for wastewater treatment services. Operating expenses include the costs associated with the conveyance and treatment of wastewater and stormwater, administrative expenses, and depreciation on capital assets. All revenues and expenses not meeting these definitions are reported as non-operating revenues and expenses. Non-recurring projects and studies (shown as non-operating expenses) consist of expenses related to unusual charges or losses that are unlikely to occur again in the formal course of business such as work related to federally declared disasters, projects originally intended to be capitalized that changed scope when a decision was made to no longer build an asset, and any non-reimbursed work performed on assets not owned or maintained by the District but is necessary to protect District owned assets or to mitigate a threat to the health and safety of the general public. The District follows GASB Statement No. 33, Accounting and Financial Reporting for Nonexchange Transactions, which establishes accounting and financial reporting standards for nonexchange transactions involving financial or capital resources. GASB Statement No. 33 groups nonexchange transactions into the following four classes, based upon their principal characteristics: derived tax revenues, imposed nonexchange revenues, government-mandated nonexchange transactions, and voluntary nonexchange transactions. The District recognizes assets from imposed nonexchange revenue transactions in the period when an enforceable legal claim to the assets arises or when the resources are received, whichever occurs first. Revenues are recognized in the period when the resources are required to be used for the first period that use is permitted. The District recognizes revenues from property taxes, net of estimated refunds and estimated uncollectible amounts, in the period for which the taxes are levied. Imposed nonexchange revenues also include licenses, permits, and other fees. Intergovernmental revenues, representing grants and assistance received from other governmental units, are generally recognized as revenues in the period when all eligibility requirements, as defined by GASB Statement No. 33, have been met. Any resources received where all requirements are met with the exception of the time requirement are recorded as deferred inflows. All other resources received before any other eligibility requirements are met are reported as unearned revenues. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 28 Cash and Cash Equivalents The District considers highly liquid investments that have original maturity of less than 91 days to the District to be Cash Equivalents. Investments The District accounts for its investments at fair value. The District categorizes its fair value measurements within the fair value hierarchy established by generally accepted accounting principles pursuant to GASB Statement No. 72, Fair Value Measurement and Application. The hierarchy is based on the valuation inputs used to measure the fair value of the asset. Level 1 inputs are quoted prices in active markets for identical assets; Level 2 inputs are significant other observable inputs; Level 3 inputs are significant unobservable inputs. Changes in unrealized gain (loss) on the carrying value of investments are reported as a component of investment income in the Statements of Revenues, Expenses and Changes in Net Position. Restricted Cash, Cash Equivalents and Investments Cash, cash equivalents and investments that are externally restricted are classified as restricted assets. These assets are used to make debt service payments, maintain sinking or reserve funds, purchase or construct capital or other non-current assets or for other restricted purposes. Accounts Receivable Accounts receivable is composed primarily of charges to customers for wastewater services. Accounts are considered past due 30 days from the invoice date. Receivables are reported at their gross values net of an allowance for uncollectible amounts. This allowance for uncollectible amounts is based on historical collection experience. Throughout the fiscal year unbilled sewer service charge revenues are accrued by the District based on estimated billings for services provided and then actual unbilled sewer service charge revenue is accrued at the end of the fiscal year as all ratepayers are billed in the following month for the previous calendar month’s services with the billings spread over twenty-three different billing cycles. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 29 Capital Assets Acquired capital assets are recorded at historical cost on the acquisition date. In accordance with GASB Statement No. 72, donated capital assets are recorded at their estimated acquisition value at the acquisition date. Depreciation is calculated on a straight-line basis over the following estimated useful lives: When developing user charge rates, the District includes funding for replacement cost of assets, which may differ from depreciation expense recorded for financial reporting purposes. Normal maintenance and repairs that do not add to the value of the asset or materially extend asset lives are not capitalized. Betterments are capitalized and depreciated over the remaining useful lives of the related assets, as applicable. The District defines capital assets as assets with an initial, individual cost between $5,000 and $15,000, depending on the asset category, and an estimated useful life of at least three years. At the time of retirement or disposal of capital assets, the related cost and accumulated depreciation are removed from the accounts and the resulting net gain or loss on disposal and sale of capital assets is reflected in non- operating expenses. Costs incurred for capital construction and acquisition are carried in construction in progress until completion of the related projects. The major components of construction in progress are the costs incurred to construct new tunnels, storage facilities and sewer lines, rehabilitate and separate existing sewer lines, and to make improvements to pump stations and treatment plants. Costs related to projects not pursued are expensed when terminated. Supplies Inventory Supplies inventory consists of parts and supplies to be used to operate and maintain treatment facilities and various treatment-related equipment at the District. This inventory figure is netted against those materials and supplies deemed to be potentially obsolete. All inventory is stated at weighted average cost and expenses are recognized when the inventory is consumed. Class of Assets Useful Life in years Buildings (recorded within other categories) 20 to 50 Collection System 20 to 100 Pumping System 5 to 50 Treatment & Disposal Plant 5 to 50 Vehicles 7 to 10 General Support Equipment & Furniture 3 to 10 THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 30 Net Position One component of the District’s net position is the net investment in capital assets which consists of capital assets, net of accumulated depreciation, reduced by the net outstanding debt and construction-related liabilities, including premiums and discounts on such debt, which is attributable to the acquisition, construction, or improvement of those assets. The outstanding debt is net of the cash and investments from the debt that has not yet been expended. Deferred gains and losses on refundings are also included in the net investment in capital assets net position. The restricted component of net position consists of assets and liabilities regulated by external constraints imposed by creditors, grantors, contributors, laws, or regulations of other governments or constraints imposed by law through constitutional provisions or enabling legislation. Property taxes levied by the various subdistricts and other revenues received for construction in those sub- districts have also been restricted for that use. Sewer extension and connection fees, grants, and other revenues received for construction within certain sub- districts have been restricted for that use. In addition, a portion of wastewater sewer charges have been restricted for the payment of principal and interest, including accrued interest, on outstanding debt of the District. The unrestricted net position component of net position consists of net position that does not meet the definition of restricted or net investment in capital assets. The District first applies restricted resources when an expense is incurred for purposes for which both restricted and unrestricted net position is available. Deferred Outflows of Resources and Deferred Inflows of Resources In addition to assets, financial statements may report a separate section for deferred outflows of resources. Deferred outflows of resources represent a consumption of net assets that applies to future reporting periods and will not be recognized as an outflow of resources until then. Deferred outflows of resources related to refunding long-term debt is reported in the Statements of Net Position. A deferred bond refunding amount results from the difference in the carrying value of refunded debt and its reacquisition price which is amortized over the shorter of the life of the refunded or refunding debt. The pension related deferred outflows of resources represent contributions made to the plan between the measurement date of the pension liability and the beginning of the next fiscal year as well as certain actuarial differences and changes that are amortized over future periods. The other postemployment benefit (“OPEB”) related deferred outflows of resources represent benefit payments made between the measurement date of the total OPEB liability THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 31 and the beginning of the fiscal year following the measurement date and certain actuarial differences and changes that are amortized over future periods. In addition to liabilities, financial statements may report a separate section for deferred inflows of resources. Deferred inflows of resources represent an acquisition of net assets that applies to future reporting periods and so will not be recognized as an inflow of resources until then. Deferred inflows of resources related to refunding long-term debt is also reported in the Statements of Net Position due to the recognition of a deferred gain resulting from the difference in the carrying value of refunded debt and its reacquisition price and this gain is amortized over the shorter of the life of the refunded or refunding debt. The District also has deferred inflows of resources related to certain changes in pension, leases and OPEB obligations that are amortized over future periods. Lease-related amounts are recognized at the inception of leases in which the District is the lessor. The deferred inflow of resources is recorded in an amount equal to the corresponding lease receivable plus certain ancillary amounts received from the lessee at or before the commencement of the lease term that relate to future periods, less any lease incentives paid to, or on behalf of, the lessee at or before the commencement of the lease term. Subsequently, the deferred inflow of resources is recognized as revenue over the life of the lease term. Capital Contributions Capital contributions to the District represent government grants and other aid used to fund capital projects and are reported at their estimated acquisition value. In accordance with GASB Statement No. 33, capital contributions are recognized as revenue when the expenditure is made and the amount becomes subject to claim for reimbursement. Bonds, Bond Premiums, Discounts and Issuance Costs Bonds and notes payable are recorded at the principal amount outstanding and are reported net of any applicable bond premium or discount. In the District’s financial statements, bond premiums and discounts are amortized over the life of the bonds using the effective interest method. Bond issuance costs are expensed when incurred pursuant to GASB Statement No. 65, Items Previously Reported as Assets and Liabilities. Bonds which have been advance refunded and in substance defeased are not included in long-term debt and the related assets deposited in an irrevocable trust with an escrow agent to provide for all future debt service payments on the refunded debt are not included in investments. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 32 Compensated Absences Vacation Under the terms of the District’s personnel policies, employees are allowed to carry a maximum of 30 to 45 days of vacation (depending on length of service) from one calendar year to the next. Since vacation remaining at year-end is expected to be used by the employee during the following fiscal year, the value is reported as a component of current deposits and accrued expenses payable. Sick Leave Employees earn sick pay benefits ranging from 10 days per year to 12 days per year (depending on length of service). Unused sick leave can be carried over at year-end without limitation. An employee retiring or an employee who dies while in active service with five or more years of service with the District, will be compensated for any unused accrued sick leave at the rate of 1.25% for each year of District service multiplied by the unused accrued sick leave remaining at the employee’s current rate of pay up to a maximum of $50,000. The District has recorded a liability which has been actuarially determined to be equal to the accumulated expense charge that will amortize the employees’ benefits over their period of District service. The liability, included in current deposits and accrued expenses payable, includes vested accumulated rights to receive sick leave benefits estimated to be paid within one year. The portion of sick leave expected to be paid after one year is recorded as a component of non-current deposits and accrued expenses payable. Pensions For purposes of measuring the net pension liability, deferred outflows of resources and deferred inflows of resources related to pensions, and pension expense, the fiduciary net position of The Metropolitan St. Louis Sewer District Employees’ Pension Plan (“Pension Plan”) and additions to/deductions from the Pension Plan’s fiduciary net position have been determined on the same basis as they are reported by the Pension Plan, which has a December 31 reporting period. For this purpose, benefit payments are recognized when due and payable in accordance with the benefit terms. Investments are reported at fair value. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts in the financial statements. Actual results could differ from those estimates. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 33 Income Tax Status The District is exempt from federal income tax under the Internal Revenue Code as a political subdivision of the State of Missouri. Adoption of New Accounting Standards During fiscal year 2023, the District implemented GASB Statement No. 96, Subscription-Based Information Technology Arrangements (SBITAs) (“GASB Statement No. 96”). SBITAs, which include software contracts, are reported in the applicable government-wide financial statements. A SBITA is a contact that conveys control of the right to use another party’s (a SBITA vendor’s) information technology (IT) software as specified in the contract for a period of time in an exchange or exchange-like transaction. SBITA contracts contain non-cancellable terms of 12 months or greater; OR non-cancellable terms of 12 months or less with the option to extend (regardless of the probability of being exercised). SBITAs are recorded at the net present value of subscription payments expected to be made during the subscription term, plus any payments made to the SBITA vendor before the commencement of the subscription term and certain direct costs (less any incentives). A subscription asset should be amortized over the shorter of the subscription term or the useful life of the underlying IT asset. This resulted in the District retroactively restating the beginning balance of net position due to the recognition of subscription asset and subscription liability. The cumulative effect of applying GASB Statement No. 96 and the resulting restatement of beginning net position on the District’s Statements of Revenues, Expenses, and Changes in Net Position is detailed as follows: July 1, 2022 Net Position - Beginning Of Year, As Previously Stated 3,033,641,753$ Effect of Adoption of GASB 96 569,253 Net Position - Beginning Of Year, As Restated 3,034,211,006$ Effect of Adoption of GASB 96 - Restatement Consists Of Subscription asset, net of amortization 20,829,071$ Recognition of interest payable reported as contracts and accounts payable (21,231) Subscription liablity (20,238,587) Effect of Adoption of GASB 96 569,253$ THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 34 During fiscal year 2022, the District implemented GASB Statement No. 87, Leases, (“GASB Statement No. 87”). GASB Statement No. 87 requires recognition of certain lease assets and liabilities for leases that previously were classified as operating leases and recognized inflows of resources or outflows of resources based on the payment provisions of the contract. It established a single model for lease accounting based on the foundational principle that leases are financings of the right to use an underlying asset. A lessee is required to recognize a lease liability and an intangible right-to-use lease asset, and a lessor is required to recognize a lease receivable and deferred inflow of resources. The District’s adoption of GASB Statement No. 87 in fiscal year 2022 resulted in retroactively restating the beginning balance of net position due to the recognition of lease receivable, right of use lease asset, lease liability, and deferred inflow of resources. The cumulative effect of applying GASB Statement No. 87 and the resulting restatement of beginning net position on the District’s Statement of Revenues, Expenses, and Changes in Net Position is detailed as follows: During fiscal year 2022, the District implemented GASB Statement No. 98, The Annual Comprehensive Financial Report. This statement establishes the term annual comprehensive financial report and its acronym, ACFR. That new term and acronym replaces the prior name, comprehensive annual financial report, and its acronym.

LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 35 During fiscal year 2022, the District implemented portions of GASB Statement No. 99, Omnibus 2022. This statement clarified provisions in GASB Statement No. 87, Leases, relating to the determination of the lease term, classification of a lease as a short-term lease, recognition and measurement of lease liability and a lease asset, and identification of lease incentives. This statement also clarified provisions in GASB Statement No. 96, Subscription-Based Information Technology Arrangements, related to the subscription-based technology arrangement (SBITA) term, classification of a SBITA as a short-term SBITA, and recognition and measurement of a subscription liability. During fiscal year 2022, the District implemented all applicable and relevant sections of Implementation Guide No. 2019-3, Leases, for which the objective of this Implementation Guide is to provide guidance that clarifies, explains, or elaborates on the requirements of Statement No. 87, Leases. The following GASB Statements which became effective during fiscal year 2023 and 2022 are not applicable to the District and there is no implementation impact on the District’s financial reporting at this time. •Statement No. 91, Conduit Debt Obligations (fiscal 2023) •Statement No. 92, Omnibus 2020 (fiscal 2022) •Statement No. 93, Replacement of Interbank Offered Rates (fiscal 2022) •Statement No. 94, Public-Private and Public-Public Partnerships and Availability Payment Arrangements (fiscal 2023) Recent Accounting Standards GASB has issued additional guidance that is not yet effective. The District is currently reviewing the provisions of the following GASB Statements to determine the impact of implementation in future periods. •Statement No. 100, Accounting Changes and Error Corrections (fiscal 2024) •Statement No. 101, Compensated Absences (fiscal 2025) Reclassifications Prior period financial statement amounts may have been reclassified to conform to current period presentation. These reclassifications had a $728,018 increase to fiscal year 2022’s total net position. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 36 2. Deposits and Investments Deposits At June 30, 2023, the reported amount of the District’s deposits was $(8,339,089) and the bank balance was $2,561,159. Of the bank balance, $411,691 was covered by the Federal Deposit Insurance Corporation (“FDIC”); $2,149,468 was collateralized with securities held by a third-party financial institution in the District’s name. In addition, the District has money market mutual funds of $23,107,546 held in a trusted escrow account for the State that will be used to make future bond payments. At June 30, 2022, the reported amount of the District’s deposits was $63,887,919 and the bank balance was $73,069,173. Of the bank balance, $936,976 was covered by the Federal Deposit Insurance Corporation (“FDIC”); $72,132,197 was collateralized with securities held by a third-party financial institution in the District’s name. In addition, the District has money market mutual funds of $21,617,850 held in a trusted escrow account for the State that will be used to make future bond payments. Custodial credit risk for deposits is the risk that, in the event of bank failure, the District’s deposits may not be returned to the District. Deposits in each bank are insured by the FDIC in the amount of $250,000 for interest bearing accounts and noninterest bearing accounts. The District’s investment policy complies with the provisions of state laws and requires collateralization on repurchase agreements, time certificates of deposit and deposits with banking institutions that are not covered by the FDIC, and the collateralization level shall be 103% and shall be based on the fair value of the pledged collateral. Investments The Secretary-Treasurer is authorized to invest, with the approval of the Board, funds not immediately needed for the purpose to which said funds are applicable, in the same manner as the state treasurer may invest funds of the State of Missouri pursuant to Section 15, Article IV of the Constitution of Missouri, as amended from time to time. The District’s investment policy conforms to the investment policy guidelines for the State of Missouri. The District’s investment policy authorizes the District to invest in the following instruments: U.S. Treasury obligations, certificates of deposit, obligations of any agency or instrumentality of the U.S., repurchase agreements, bankers’ acceptances, and commercial paper, all according to terms specified in the policy. The District also has investments in money market mutual funds that hold securities approved by the District’s investment policy. At June 30, 2023, and June 30, 2022, all of the District’s investments were in compliance with the District’s investment policy and Charter. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 37 A summary of deposits and investments as of June 30, 2023, and June 30, 2022 is as follows: A reconciliation to the Statements of Net Position is as follows: Investment Type Cost Fair Value Cost Fair Value Deposits (8,339,089)$ (8,339,089)$ 63,887,919$ 63,887,919$ Money Market Mutual Funds 23,107,546 23,107,546 21,617,850 21,617,850 U.S. Treasury and Agency Obligations 542,728,000 522,995,614 501,598,900 489,050,072 Commercial Paper 93,925,000 93,148,355 173,000,000 172,251,461 Total 651,421,457$ 630,912,426$ 760,104,669$ 746,807,302$ 2023 2022 THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 38 Interest Rate Risk As of June 30, 2023, and 2022, the District had the following investments and maturities: In accordance with the District’s investment policy, the District will minimize the risk that the fair value of debt securities in the portfolio will fall due to increases in general interest rates by: 1. Structuring the investment portfolio so that securities mature to meet cash requirements for ongoing operations, thereby avoiding the need to sell securities on the open market prior to maturity; 2. Investing operating funds primarily in short-term securities; 3. Complying with state law which limits the maximum stated maturities to five years on any investment from the date of purchase. Long-Term Investments While the majority of the District’s portfolio is made up of short-term investments, the District also categorizes a sizeable amount as long-term under the categories discussed in Note 1, Summary of Significant Accounting Policies. The District is allowed to purchase long-term callable securities. These callable securities give the issuer the right to redeem at predetermined prices at a specific time prior to maturity. When a security is called, the District reflects an immediate reclassification from long-term investment to cash.

These 2023A bonds were issued to fully refund the Series 2013B bonds maturing in fiscal years 2030 through 2039 totaling $31,775,000. Proceeds of $32,476,938, (including a premium of $5,466,911 and $3,990,027 in excess debt service reserves contributed by the District) were used to refund the remaining outstanding balance of the 2013B bonds and the $701,938 interest accrued thereon. The related liability for the 2013B bonds refunded was removed from the District’s financial statements in fiscal 2023. This direct placement refunding decreased total debt service payments by $12,365,938, resulting in an economic gain (difference between the present values of the debt service requirements on the old and new debt adjusted for the additional cash paid) of $6,069,392. These Series 2023A senior direct placement bonds have interest rates of $5.00% and are payable in semiannual installments at varying amounts through May 1, 2039.

THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 77 8. Pension Plan General Information About the Pension Plan Pension Plan Description. The Metropolitan St. Louis Sewer District Employees’ Pension Plan (“Pension Plan”) is a noncontributory single employer defined benefit plan providing retirement benefits as well as death and disability benefits. As a condition of employment, all full-time employees of the District commencing service prior to January 1, 2011, were eligible to be covered by the Pension Plan. As of January 1, 2011, the Pension Plan was frozen to new employees. Instead, new employees of the District may participate in The Metropolitan St. Louis Sewer District Defined Contribution Plan (“DC Plan”) and/or The Metropolitan St. Louis Sewer District Deferred Compensation Plan and Trust. Current employees with less than ten years of service on January 1, 2011, could also voluntarily elect to transfer from the Pension Plan and enter the DC Plan. Benefits Provided. All benefits vest after five years of credited service. Members retiring at or after age 65 with five or more years credited service are entitled to a pension benefit. The Pension Plan permits early retirement with reduced benefits beginning at age 55 if the member has completed five years of employment. Ordinance No. 10664 provides for unreduced retirement benefits to any member whose combined age and term of service is equal to 75. Effective August 1, 2004, Ordinance No. 11781 amended the Pension Plan to change the benefit formula to 1.7% of final average earnings plus 0.4% of final average earnings that are in excess of covered earnings multiplied by the period of years and months of credited service not to exceed 35 years without including accrued sick leave. For vested employees who retire or die while in active service, sick leave is paid out at 1.25% per year of service multiplied by the amount of the unused accrued sick leave remaining at the employee’s current rate of pay, up to a maximum of $50,000. Also, the Pension Plan was amended to provide the retiring member with a 10% partial lump sum payment option. The balance of the distribution will be paid in accordance with any one of the other payment options available under the Pension Plan. The retirement benefit payable to a member who retires after the normal retirement date is the greater of a) the benefit that would have been payable on the normal retirement date plus a special annual retirement benefit provided by the accumulated value, at 4% per annum interest, of the monthly benefit that would have been received prior to the postponed retirement date or b) the benefit determined as of the postponed retirement date under the normal formula. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 78 Effective August 27, 2011, Ordinance No. 13288 amended the Pension Plan to include the following: “Upon termination or complete discontinuance of contributions under the Pension Plan, the rights of all Members to benefits accrued to the date of such termination or discontinuance shall be non-forfeitable, to the extent then funded.” Effective September 14, 2017, Ordinance No. 14776 amended the Pension Plan to require enrollment in Medicare Parts A and B when Members first become eligible for such Medicare programs due to disability in order to receive, or continue to receive, retiree medical benefits under the Pension Plan and to clarify that any retiree medical benefits under the Pension Plan will be secondary to Medicare disability benefits in accordance with the Medicare secondary payor rules. Effective February 14, 2019, Ordinance No. 15110 amended the Pension Plan to update the language of Pension Plan benefits for death of a member after retirement and retiree medical coverage. Amounts in participants’ accounts are distributed upon retirement, death, disability, or termination of employment. The normal form of retirement benefit is either a lump sum payment or equal monthly installments. The Pension Plan reports financial data on a calendar year basis and issues a publicly available financial report that includes audited financial statements and required supplementary information. That report is available on the District’s website at msdprojectclear.org and may be obtained by writing: The Metropolitan St. Louis Sewer District, 2350 Market Street, St. Louis, MO 63103-2555.

At December 31, 2022, and 2021, the financial reporting period of the Pension Plan, the following employees were covered by the benefit terms: Increase 2022 2021 (Decrease) Active plan members 349 396 (47) Retirees and beneficiaries currently receiving benefits 862 841 21 Terminated members entitled to receive benefits 165 164 1 Total 1,376 1,401 (25) As of December 31, THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 79 Required Employer Contributions. The District’s employees do not contribute to the Pension Plan. Ordinances establishing the Pension Plan provide for actuarially determined annual contributions, paid solely by the District, that are sufficient to pay benefits when due. The Entry Age Normal actuarial funding method is used to determine contributions. Contributions of $12,631,498 and $12,243,539, excluding certain professional fees paid by the District, were made to the Pension Plan during the District’s fiscal years ended June 30, 2023, and 2022, respectively. These contributions were made in accordance with actuarially determined contribution requirements based on actuarial valuations performed at December 31, 2022, and 2021, respectively. Net Pension Liability The net pension liability was measured as of December 31, 2022, and 2021 and the total pension liability used to calculate the net pension liability was determined by an actuarial valuation as of that date. Actuarial Assumptions. The total pension liability in the December 31, 2022, and 2021 actuarial valuations were determined using the following actuarial assumptions, applied to all periods included in the measurement: Effective December 31, 2022, and December 31, 2021, for current employees, healthy retirees, disabled retirees and contingent survivors, mortality rates were based on the Pub-2010 General Amount-Weighted Mortality Tables, male and female rates, with generational projection from 2010 using MP-2021 improvement scale (improvement scale updates published annually), respectively. The actuarial assumptions are based on prior and current year experiences. Inflation 2.50 percent Salary Increases 4.25 percent, average, including inflation Investment Rate of Return 6.25 compounded annually, including inflation THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 80 Long-Term Expected Rate of Return. The long-term expected rate of return is determined by adding expected inflation to expected long-term real returns and reflecting expected volatility and correlation. The capital market assumptions at December 31, 2022, and 2021 are as follows: Long-Term Expected Arithmetic Target Real Rate Asset Class Allocation of Return US Large Cap Equity 25.0% 4.0% Domestic Core Bonds 14.0% 1.6% Core "Plus" Bonds 13.0% 2.1% Real Estate 12.0% 3.7% International Equity 12.0% 5.2% US Small Cap Equity 10.0% 4.7% Global Bonds 8.0% 0.4% Emerging Markets Equity 6.0% 6.2% Total 100.0% December 31, 2022 Long-Term Expected Arithmetic Target Real Rate Asset Class Allocation of Return Large Cap US Equity 25.0% 4.0% Domestic Core Bonds 14.0% -0.2% Core "Plus" Bonds 13.0% 0.4% Real Estate 12.0% 2.7% Developed International Equity 12.0% 5.0% Small Cap US Equity 10.0% 4.5% Global Fixed Income 8.0% 3.4% Emerging Markets Equity 6.0% 5.6% Total 100.0% December 31, 2021 THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 81 Discount Rate. The discount rate used to measure the total pension liability at both December 31, 2022, and 2021, was 6.25 percent. The Pension Plan’s fiduciary net position was projected to be available to make all projected future benefit payments of current active and inactive employees. Therefore, the discount rate for calculating the total pension liability is equal to the long-term expected rate of return.

LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 86 The Pension Plan will minimize the risk that the market value of securities in the portfolio will fall due to changes in general interest rates by: Structuring the investment portfolio so that securities mature to meet cash requirements for benefit payments, thereby avoiding the need to sell securities on the open market prior to maturity; and Monitoring fixed income investment managers’ performances to be sure the fixed income portion of the investment portfolio is managed to predetermined indexes. Credit Risk Investment credit risk is the risk that the issuer or other counterparty to an investment will not fulfill its obligations. The Pension Plan does not have a formal credit risk policy. The Pension Plan will minimize credit risk by: Pre-qualifying the financial institutions, broker/dealers, intermediaries, and advisors with which the Pension Plan will do business; and Diversifying the portfolio so that potential losses on individual securities will be minimized.

Fiduciary Pension Trust Fund Fair Value Measurement and Application The Pension Plan categorizes its fair value measurements within the fair value hierarchy established by U.S. generally accepted accounting principles. The hierarchy is based on the valuation inputs used to measure the fair value of the asset and give the highest priority to unadjusted quoted process in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The Pension Plan had the following fair value measurements of invested assets as of December 31, 2022, and December 31, 2021: Investments Measured at Fair Value Fair Value Measurements Using Quoted Prices in Active Significant Markets for Other Significant Identical Observable Unobservable Assets Inputs Inputs Investments by Fair Value Level 12/31/2022 (Level 1) (Level 2) (Level 3) Debt Securities: Corporate Obligations 23,878,019$ —$ 23,878,019$ —$ US Treasury Notes and Bonds 11,174,481 11,174,481 — — US Government Agency Obligations 4,615,779 — 4,615,779 — Municipal Obligations 1,542,370 — 1,542,370 — Total Debt Securities 41,210,649 11,174,481 30,036,168 — Equity Securities: Domestic Equities 16,463,329 16,463,329 — — International Equities 36,796,272 — 36,796,272 — Emerging Markets Fund 17,581,620 — 17,581,620 — Total Equity Securities 70,841,221 16,463,329 54,377,892 — Total Investments by Fair Value Level 112,051,870 27,637,810$ 84,414,060$ —$ Unfunded Redemption Redemption Investments Measured at the Net Asset Value (NAV)Commitments Frequency Notice Period Domestic Equities (1)87,212,430 — Daily Varies Core Plus Bond Commingled Trust Fund (2)39,028,527 — Daily 1 Day Real Estate Funds (3)24,002,654 — Quarterly 60 Days Global Fixed Income Collective Trust Fund (4)21,875,375 — Daily 10 Days Diversified Hedge Fund of Fund (5)130,870 — Quarterly 90 Days Total Investments Measured at the Net Asset Value 172,249,856 Money Market at Amortized Cost 5,073,752 Total Investments at Fair Value 289,375,478$ THE METROPOLITAN ST.

Other Retirement Plans Deferred Compensation Plan and Trust The District offers its employees a deferred compensation plan created in accordance with Internal Revenue Code Section 457. The Metropolitan St. Louis Sewer District Deferred Compensation Plan and Trust (“Plan”), available to all District employees, permits them to defer a portion of their salary up to Internal Revenue Code limits. The District does not contribute to the Plan except where mandated by the Internal Revenue Service to compensate participants for lost deferral contributions. The deferred compensation is not available to employees until termination, retirement, death, disability or due to financial hardship as defined by the Plan. At June 30, 2023 and 2022, the District had outstanding liabilities owed to the Plan of $202,282 and $192,964, respectively. The Plan was amended and restated to comply with the Economic Growth and Tax Relief Reconciliation Act of 2001 (“Act”). The Act made significant changes to Section 457(b) of the Internal Revenue Code of 1986, as previously amended. The Plan assets are held in trust for the exclusive benefit of participants and their beneficiaries under Section 1448 of the Small Business Job Protection Act of 1996. As a result, the assets and liabilities of the Plan are not included in the accompanying financial statements. The Metropolitan St. Louis Sewer District Deferred Compensation Plan and Trust issues a publicly available financial report that includes audited financial statements and supplementary information. That report is available on the District’s website at msdprojectclear.org and may be obtained by writing: The Metropolitan St. Louis Sewer District, 2350 Market Street, St. Louis, MO 63103- 2555. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 92 Defined Contribution Plan The Metropolitan St. Louis Sewer District Defined Contribution Plan (“DC Plan”) was established by the District’s Board of Trustees, through Ordinance 13180, which became effective January 1, 2011. The following full-time employees are eligible to participate in the DC Plan: (i) employees first hired on or after January 1, 2011, and (ii) employees hired prior to January 1, 2011, who elected to terminate participation in The Metropolitan St. Louis Sewer District Employees’ Pension Plan (“Pension Plan”), effective as of April 1, 2011, in accordance with the provisions of such Pension Plan, and (iii) employees rehired on or after January 1, 2011, who are not eligible to accrue benefits under the Pension Plan. An employee shall become a participant in the DC Plan on the first day on which he or she performs an hour of service for the District. The District’s Board of Trustees, primarily to improve benefits to members, amends the DC Plan in all its respects. A pension committee consisting of two members of the District’s Board of Trustees, two elected employee members and four members of the District’s management staff administer the DC Plan. A committee of the District’s Board of Trustees, with the aid of an investment advisor, reviews and evaluates the DC Plan’s investment options and the related rates of return on a periodic basis. This DC Plan is intended to provide a means whereby the District may provide retirement benefits to eligible employees and encourage such employees to establish a regular method of savings, thereby providing a measure of financial security for such employees and their beneficiaries upon retirement or in the event of death or disability. All assets of the DC Plan are the sole property of the DC Plan and are not subject to the claims of creditors of the District and the assets and liabilities of the DC Plan are not included in the accompanying financial statements. Employer Basic Contributions: For each payroll period, the District contributes an amount equal to 7% of the covered compensation earned during such period by each participant entitled to an allocation of such contribution. Upon a participant’s severance from service, the unvested amount credited to his/her individual account shall be forfeited and credited to the Employer Basic Contributions account and shall be used to reduce future Employer Basic Contributions. If a participant is rehired before incurring two consecutive years break in service, the amount previously forfeited will be restored. If rehired after two consecutive years of break in service, the amounts previously forfeited will not be restored. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 93 Employer Matching Contributions: For each payroll period, the District contributes an amount equal to 50% of the covered compensation of such participant withholding as an annual deferral (as defined in The Metropolitan St. Louis Sewer District Deferred Compensation Plan and Trust) pursuant to The Metropolitan St. Louis Sewer District Deferred Compensation Plan and Trust; provided that, before-tax contributions in excess of 4% of the covered compensation of the participant for the payroll period shall not be considered for purposes of Employer Matching Contributions. Employer Matching Contributions shall be up to the maximum amount of compensation that may be taken into account for the DC Plan year and the amount credited to the participant’s Employer Matching Contributions Account shall be fully vested at all times. In no event shall the sum of the employer contributions and employee contributions allocated to the account of a participant for the DC Plan year exceed the lesser of: (a) The amount specified in the applicable Internal Revenue Code, as adjusted annually for any applicable increases in the cost of living. (b) 100% of the participant’s compensation for such year. The compensation limit referred to in (b) shall not apply to any contribution from medical benefits after separation from service. The District’s contributions to the DC Plan amounted to $3,194,880 and $3,034,606 for the years ended June 30, 2023, and 2022, respectively. Forfeitures were $230,743 and $214,069, for the years ended June 30, 2023, and 2022, respectively, and the balances in the prepaid forfeitures account as of June 30, 2023, and 2022 were $17,551 and $17,508, respectively. At June 30, 2023 and 2022, the District had outstanding liabilities owed to the DC Plan of $134,962 and $118,731, respectively. THE METROPOLITAN ST.

Postemployment Benefits Other Than Pensions (“OPEB”) General Information About The OPEB Plan Plan Description. The District’s defined benefit OPEB plan, The Metropolitan St. Louis Sewer District Retiree Medical Coverage Plan (“OPEB Plan”), provides retiree medical coverage for all permanent full-time employees who retire from the District on or after age 62 with five years of service or whose age plus years of service equal 75 points (“Rule of 75”) as part of a total compensation package effective August 1, 2004 for general employees and, with respect for union members, the later of August 1, 2004 or the date of union ratification of a Memorandum of Understanding with respect to this Plan modification. The OPEB Plan is a single employer defined benefit OPEB plan administered by the District. The OPEB Plan was established by Ordinance No. 9826 and became effective January 1, 1996. This ordinance has been repealed and new ordinances enacted in lieu thereof with Ordinance No. 15109 covering defined contribution retirees and Ordinance No. 15110 covering defined benefit retirees, both of which were adopted on February 14, 2019. Ordinance 15109 has been repealed and a new ordinance enacted in lieu thereof with Ordinance No. 15961 covering defined contribution retirees and adopted on July 14, 2022, being the most current ordinances covering the OPEB Plan in its entirety. The District offers two medical plan options, a traditional open access plan and a high deductible health plan, and both plans offer THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 95 wellness rates for those employees who qualify. No assets are accumulated in a trust that meets the criteria in paragraph 4 of GASB Statement No. 75, Accounting and Financial Reporting for Postemployment Benefits Other Than Pension (“GASB Statement No. 75”). Benefits Provided. The OPEB Plan provides healthcare for qualified retirees and their dependents. The District pays the same amount of the monthly group health insurance premium for the qualified retiree as it would for an active single employee until the retiree becomes eligible for Medicare at age 65. In the last six months of fiscal year 2023 the monthly amount the District paid towards all premiums remained the same as the first six months of fiscal year 2023 due to the lack of a rate increase. Retiree premium was $647.22 for retirees qualifying for the wellness incentive ($658.06 for retirees with wellness qualified spouse). The $647.22 paid by the District equates to 86% of the traditional plan’s premium and 92% of the high deductible plan’s premium. For retirees not qualifying for the wellness incentive, the District paid $603.89 of the premium which equates to 80% for the traditional plan and 86% for the high deductible plan. The retiree paid 100% of the spousal, children or family premium incremental increases in addition to the remaining 8-20% of the retiree’s total monthly premium. The OPEB Plan also provided life insurance coverage for a very small, closed group of disabled former employees. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 96 The monthly premiums for calendar year 2023 plans and coverage tiers are as follows: In fiscal year 2022, and in the first six months of fiscal year 2023, the monthly amount the District paid towards the retiree’s premium was $647.22 for retirees qualifying for the wellness incentive ($658.06 for retirees with wellness qualified spouse). The $647.22 paid by the District equates to 86% of the traditional plan’s premium and 92% of the high deductible plan’s premium.

LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 98 Total OPEB Liability The District’s total OPEB liability measured as of December 31, 2022, and December 31, 2021, was $26,108,766 and $26,793,582, respectively. The District’s total OPEB liabilities for both years were determined based on an actuarial valuation date of June 30, 2021 and were calculated based on the discount rates and actuarial assumptions below and were then projected forward to the measurement dates. Actuarial Assumptions and Other Inputs. The total OPEB liabilities based on the June 30, 2021, actuarial valuation was determined using the following actuarial assumptions and other inputs, applied to all periods included in the measurement, unless otherwise specified: The discount rate was based on the 20 Year Bond General Obligation Index.

OPEB Expense and Deferred Outflows of Resources and Deferred Inflows of Resources Related to OPEB For the years ended June 30, 2023, and 2022, the District recognized OPEB expense of $2,630,534 and $2,606,467, respectively. At June 30, 2023 and 2022, the District reported deferred outflows of resources and deferred inflows of resources related to OPEB from the following sources: In the years ending June 30, 2023, and 2022, amounts currently reported as deferred outflows of resources, $941,912 and $926,270, respectively, related to the District’s benefit payments subsequent to the measurement date and will be recognized as a reduction of the total OPEB liability in the years ended June 30, 2024 and 2023, respectively.

LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 102 Other amounts reported as deferred outflows of resources and deferred inflows of resources related to OPEB will be recognized in OPEB expense as follows: 13. Self-Insurance Programs The District is exposed to various risks of loss related to torts; theft of, damage to, and destruction of assets; errors and omissions; injuries to employees; and natural disasters. The District has established a risk management program and retains the risk related to its obligation to provide workers' compensation and medical and hospitalization benefits to its employees; and to pay water backup claims to its customers. The estimated liabilities for payment of incurred (both reported and unreported) but unpaid claims relating to these matters are included as a component of current deposits and accrued expenses, and as such, are expected to be paid within one year of the date of the Statement of Net Position. At June 30, 2023 and 2022, these liabilities amounted to $6,268,562 and $5,057,417, respectively. The claims liabilities reported are based on the requirements of GASB Statement No. 10, Accounting and Financial Reporting for Risk Financing and Related Insurance Issues, which requires that a liability for claims be reported if information obtained prior to the issuance of the financial statements indicates it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated. Changes in the balance of claims liabilities during fiscal 2023, 2022, and 2021 were as follows: Net Deferrals of Resources Year ended June 30: 2024 (207,908)$ 2025 (207,908) 2026 (207,908) 2027 (207,908) 2028 (200,761) Thereafter (493,062) (1,525,455)$ THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 103 The District obtains periodic funding valuations from the third-party administrators managing the self-insurance programs and adjusts the charges as required to maintain the appropriate level of estimated claims liability. The District also maintains excess liability insurance coverage for workers' compensation and medical and hospitalization claims; general liability; and water backup damage to customers’ property. The District purchases commercial insurance for all other risks of loss. Settled claims have not exceeded this commercial coverage in any of the past three years. 14. Closure and Post-Closure Care Costs State and federal laws and regulations require the District to place a final cover on its Prospect Hill Reclamation Project landfill site when it stops accepting waste and to perform certain maintenance and monitoring functions at the site for 30 years after closure. Although closure and post-closure care costs will be paid only near or after the date that the landfill stops accepting waste, the District reports a portion of these closure and post-closure care costs as an operating expense in each fiscal year. The $713,441 and $750,948 reported as landfill closure and post- closure care liabilities at June 30, 2023 and 2022, respectively, represent the cumulative amounts reported at fiscal year-end and represent 69.9% of the estimated closure and post-closure care costs of the landfill for fiscal years ended June 30, 2023 and 2022. These amounts are based on what it would cost to perform all closure and post-closure care in 2023 and 2022, respectively. The remaining disposal life estimate was calculated in 2009 and was estimated at eight years factoring in a future annual average disposal rate of 96,500 cubic yards. It was noted in the 2009 Black and Veatch study that this life could be extended further if the actual disposal rate is less than projected or alternative uses and off- site beneficial options for the incinerator ash are later developed. Since the actual average disposal rate has been less than 96,500 cubic yards, the landfill is not at capacity and MSD expects the landfill to be in use for another 8-11 years and the total capacity of the landfill and the available space as of 2022 was adjusted. In addition, a new survey of the landfill was performed in 2022 which increased the remaining capacity due to settlement and minor vehicle compaction. The District will continue to accrue the remaining estimated cost of closure and post-closure care annually. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 104 The District is required to demonstrate that it has the financial capability to close the landfill to the State of Missouri through the use of a financial test as specified in 10 CSR 80-2.030(4)(D)6 of the Missouri Solid Waste Management Rules. The District has complied with the State’s requirement. The District recognizes that estimates of closure costs may change as a result of inflation, deflation, and/or changes in technology and applicable laws and regulations. If closure cost estimates change, the liability currently reported on the Statements of Net Position will be adjusted accordingly. 15. Commitments And Contingencies United States And State Of Missouri V. Metropolitan St. Louis Sewer District; In The United States District Court For The Eastern District Of Missouri; Case No. 07-1120. On April 27, 2012, the Court entered the consent decree (“CD”) involving the Environmental Protection Agency, Missouri Department of Natural Resources, Missouri Coalition for the Environment and The Metropolitan St. Louis Sewer District (“MSD”). At the time the District entered into the CD, the CD required the District to spend approximately $4.7 billion, in 2010 dollars, over a 23-year implementation period. Throughout this period improvements will be made to the District’s separate sewer system, combined sewer system, and wastewater treatment plants. On June 1, 2011, the State of Missouri approved Chapter 11, Chapter 12, and Appendix Q of the District’s Combined Sewer Overflow Long-Term Control Plan Updated Report, dated February 2011. On June 22, 2018, a United States District Judge approved an amendment to the CD to extend it by five years from a 23-year program to a 28-year program. Recent regulatory changes have compelled MSD to accelerate certain non-consent decree work. This amendment will allow MSD to meet these new regulatory requirements in a fiscally responsible way while better controlling rate increases over the coming years. In 2023 dollars the CD effort is estimated to cost $7.2 billion. The District continues to comply with the CD. Other Commitments and Contingencies The District is a defendant in various other matters of litigation. Of these matters, management and District’s legal counsel do not anticipate any material effect on the June 30, 2023 and 2022 financial statements. The District has entered into construction and other contracts amounting to approximately $634,000,000 and $540,000,000 at June 30, 2023 and 2022, respectively, and through the respective audit report date. The District had THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 105 $628,219,393 and $744,149,393 in revenue bonds authorized by the voters but unissued as of June 30, 2023 and 2022, respectively. 16. Restricted Net Position The Statements of Net Position report $106,786,576 and $96,029,444 of restricted net position at June 30, 2023 and 2022, respectively, of which $83,139,418 and $71,883,165 are restricted due to enabling legislation, as of June 30, 2023 and 2022, respectively. 17. Segment Information The District issued wastewater revenue bonds to finance wastewater infrastructure projects. The District accounts for both wastewater and stormwater activities in a single enterprise fund, but investors in those bonds rely solely on the revenue generated by the wastewater activities for repayment. Fiscal year 2023 and 2022 summary financial information for each business segment is presented below. A segment is an identifiable activity reported as a stand-alone entity for which one or more revenue bonds are outstanding. A segment has a specifically identifiable revenue stream pledged in support of the revenue bonds and has related expenses, gains and losses and assets, deferred outflows, liabilities and deferred inflows that are required by external parties to be accounted for separately. The wastewater system is the only reportable segment that meets the requirements of GASB Statement No. 34, Basic Financial Statements - and Management’s Discussion and Analysis - for State and Local Governments. The stormwater system is reported on for informational purposes only. THE METROPOLITAN ST.

Tax Abatements Tax abatements, as defined by Governmental Accounting Standards Board (“GASB”) Statement No. 77, Tax Abatement Disclosures (“GASB Statement No. 77”), are agreements between a government and an individual or entity in which the government promises to forgo tax revenues and the individual or entity promises to subsequently take a specific action that contributes to economic development or otherwise benefits the government or its citizens. This Statement requires disclosure of tax abatement information about (1) a reporting government’s own tax abatement agreements and (2) those that are entered into by other governments and that reduce the reporting government’s tax revenues. Since the District does not and has not entered into tax abatement agreements directly with any individuals or entities, the following estimates are from tax abatements entered into by other governments, specifically the county and municipalities within the District’s boundary, that have reduced the District’s tax revenues. Tax Abatements entered into by St. Louis County and Cities located in St. Louis County The District’s property tax revenues were reduced through four programs that are utilized by cities located in St. Louis County and the County itself. Summaries of these four programs are as follows: Enhanced Enterprise Zone: provides real property tax abatements to new or expanding businesses in certain specified geographic areas designated by local governments and certified by the Missouri Department of Economic Development. Industrial Development Bonds: finances industrial development projects for private corporations, partnerships and individuals. Land Clearance for Redevelopment Authority: assists with the redevelopment of blighted or insanitary areas for residential, recreational, commercial, industrial or public uses. Urban Redevelopment Corporations: provides real property tax abatements to encourage the redevelopment of blighted areas by an eligible city or county. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 115 The amount of the District’s tax revenues that were abated by the county and cities initiating the programs are reported in the following tables. THE METROPOLITAN ST. LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 116 Tax Abatements entered into by St. Louis City The City of St. Louis offers a real estate tax abatement program as a development tool designed to assist developers, businesses and individuals with renovation and new construction projects. The tax abatement freezes the tax assessment in improvements to property at the pre-development level. To be eligible for tax abatement, a significant investment must be made in the property; generally either new construction on vacant land or gut rehabilitation of an existing building. The application must be made before construction begins and the usual term for tax abatement is five to ten years. The amount of the District’s tax revenues calculated at the District’s tax rates of $.1053 and $.1078 per $100 of assessed value for fiscal 2023 and 2022, respectively, that were abated by St. Louis City are reported in the following tables.

LOUIS SEWER DISTRICT Notes to Financial Statements (Continued) Page 117 Tax Increment Financing utilized by St. Louis County, Cities located in St. Louis County and St. Louis City Missouri’s Real Property Tax Increment Allocation Redevelopment Act enables cities to finance certain redevelopment costs with the revenue generated from (i) payments in lieu of real estate taxes, as measured by the net increase in assessed valuation resulting from redevelopment and (ii) a portion of the increase in other local tax revenue associated with new economic activity. When a tax increment financing (“TIF”) plan is adopted, real estate taxes in the redevelopment are frozen at their current level. By applying the real estate tax rate of all taxing districts having taxing power within the redevelopment area to the increased assessed valuation resulting from redevelopment, a tax “increment” is produced. The real estate tax increments are referred to as payments in lieu of taxes, or “PILOTs”, and are deposited in a special allocation fund.

Changes of Assumptions. The actuarial discount rate and the long-term expected rate of return were changed to 6.25% in 2021. Both rates were changed to 6.75% in 2020 and 2019, 6.90% in 2018 and 2017 and 7.00% in 2016 and all prior years. The mortality tables utilized in 2022, 2021, 2020 and 2019 were the Pub-2010 General Amount-Weighted Mortality Tables and the effect of changing mortality tables in 2019 is also reflected in the assumption changes. In 2016, the amount reported as changes of assumptions resulted from changing to the RP-2014 Mortality for Employees and Healthy Annuitants and Disabled Mortality tables, while the 2014 change resulted primarily from adjustments to the discount rate, long-term expected rate of return, inflation and employee rate increases. 2.
