SPIRE INC., SPIRE MISSOURI INC. AND SPIRE ALABAMA INC.

NOTES TO FINANCIAL STATEMENTS

(UNAUDITED)

(Dollars in millions, except per share amounts)

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION – These notes are an integral part of the accompanying unaudited financial statements of Spire Inc. (“Spire” or the “Company”) presented on a consolidated basis, Spire Missouri Inc. (“Spire Missouri”) and Spire Alabama Inc. (“Spire Alabama”). Spire Missouri and Spire Alabama are wholly owned subsidiaries of Spire. Spire Missouri, Spire Alabama and the subsidiaries of Spire EnergySouth Inc. (“Spire EnergySouth”) are collectively referred to as the “Utilities.” The subsidiaries of Spire EnergySouth are Spire Gulf Inc. and Spire Mississippi Inc.

The accompanying unaudited financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information with the instructions to Form 10-Q and Rule 10-01 of Regulation S‑X. Accordingly, they do not include all the disclosures required for complete financial statements. In the opinion of management, the accompanying unaudited financial statements include all adjustments necessary for the fair presentation of the results of operations for the periods presented. This Form 10-Q should be read in conjunction with the Notes to Financial Statements contained in Spire’s, Spire Missouri’s and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

The consolidated financial position, results of operations, and cash flows of Spire include the accounts of the Company and all its subsidiaries. Transactions and balances between consolidated entities have been eliminated from the consolidated financial statements of Spire. In compliance with GAAP, transactions between Spire Missouri and Spire Alabama and their affiliates, as well as intercompany balances on their balance sheets, have not been eliminated from their separate financial statements.

NATURE OF OPERATIONS – Spire has two reportable segments: Gas Utility and Gas Marketing. The Gas Utility segment consists of the regulated natural gas distribution operations of the Company and is the core business segment of Spire in terms of revenue and earnings. The Gas Utility segment is comprised of the operations of: Spire Missouri, serving St. Louis, Kansas City, and other areas in Missouri; Spire Alabama, serving central and northern Alabama; and the subsidiaries of Spire EnergySouth, serving southern Alabama and south-central Mississippi. The Gas Marketing segment includes Spire’s largest gas-related business, Spire Marketing Inc. (“Spire Marketing”), which provides non-regulated natural gas services, primarily in the central and southern United States (U.S.). The activities of other subsidiaries are reported as Other and are described in Note 9, Information by Operating Segment. Spire Missouri and Spire Alabama each have a single reportable segment.

Nearly all the Company’s earnings are derived from its Gas Utility segment. Due to the seasonal nature of the Utilities’ business and the Spire Missouri rate design, earnings are typically concentrated during the heating season of November through April each fiscal year. As a result, the interim statements of income for Spire, Spire Missouri and Spire Alabama are not necessarily indicative of annual results or representative of succeeding quarters of the fiscal year.

21

REGULATED OPERATIONS – The Utilities account for their regulated operations in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 980, Regulated Operations. This topic sets forth the application of GAAP for those companies whose rates are established by or are subject to approval by an independent third-party regulator. The provisions of this accounting guidance require, among other things, that financial statements of a regulated enterprise reflect the actions of regulators, where appropriate. These actions may result in the recognition of revenues and expenses in time periods that are different than non-regulated enterprises. When this occurs, costs are deferred as assets in the balance sheet (regulatory assets) and recorded as expenses when those amounts are reflected in rates. In addition, regulators can impose liabilities upon a regulated company for amounts previously collected from customers and for recovery of costs that are expected to be incurred in the future (regulatory liabilities). Management believes that the current regulatory environment supports the continued use of these regulatory accounting principles and that all regulatory assets and regulatory liabilities are recoverable or refundable through the regulatory process.

As authorized by the Missouri Public Service Commission (MoPSC), the Mississippi Public Service Commission (MSPSC) and the Alabama Public Service Commission (APSC), the Purchased Gas Adjustment (PGA) clauses and Gas Supply Adjustment (GSA) riders allow the Utilities to pass through to customers the cost of purchased gas supplies. Regulatory assets and liabilities related to the PGA clauses and the GSA riders are both labeled Unamortized Purchased Gas Adjustments herein. See additional information about regulatory assets and liabilities in Note 4, Regulatory Matters.

DERIVATIVES – In the course of their business, certain subsidiaries of Spire enter into commitments associated with the purchase or sale of natural gas. Certain of their derivative natural gas contracts are designated as normal purchases or normal sales and, as such, are excluded from the scope of FASB ASC Topic 815, Derivatives and Hedging. Those contracts are accounted for as executory contracts and recorded on an accrual basis. Revenues and expenses from such contracts are recorded gross. Contracts not designated as normal purchases or normal sales are recorded as derivatives with changes in fair value recognized in earnings in the periods prior to physical delivery. Certain of Spire Marketing’s wholesale purchase and sale transactions are classified as trading activities for financial reporting purposes, with income and expenses presented on a net basis in natural gas expenses in the Condensed Consolidated Statements of Income.

TRANSACTIONS WITH AFFILIATES – Transactions between affiliates of the Company have been eliminated from the consolidated financial statements of Spire. As reflected in their separate financial statements, Spire Missouri and Spire Alabama borrowed funds from the Company and incurred related interest, and in 2021, Spire Alabama lent excess funds to the Company and earned related interest. Spire Missouri and Spire Alabama also participated in normal intercompany shared services transactions. Spire Missouri’s and Spire Alabama’s other transactions with affiliates are presented below:

ACCRUED CAPITAL EXPENDITURES – Accrued capital expenditures, shown in the following table, are excluded from capital expenditures in the statements of cash flows until paid.

|  | March 31, |  |  | September 30, |  |  | March 31, |
|  | 2021 |  |  | 2020 |  |  | 2020 |
Spire |  | $ | 36.1 |  |  | $ | 67.6 |  |  | $ | 51.4 |
Spire Missouri |  |  | 21.8 |  |  |  | 34.3 |  |  |  | 21.5 |
Spire Alabama |  |  | 4.7 |  |  |  | 17.0 |  |  |  | 17.6 |

ACCOUNTS RECEIVABLE AND ALLOWANCE FOR CREDIT LOSSES – Trade accounts receivable are recorded at the amounts due from customers, including unbilled amounts. Accounts receivable are written off when they are deemed to be uncollectible. An allowance for expected credit losses is estimated and updated based on relevant data and trends such as accounts receivable aging, historical write-off experience, current write-off trends, economic conditions, and the impact of weather and availability of customer payment assistance on collection trends. For the Utilities, net write-offs as a percentage of revenue has historically been the best predictor of base net write-off experience over time. Management judgment is applied in the development of the allowance due to the complexity of variables and subjective nature of certain relevant factors. For March 31, 2021, and September 30, 2020, the estimates for expected credit losses were increased as a result of considerations related to the outbreak of the novel coronavirus (COVID-19), including trends from previous economic downturns, the effects of moratoriums on gas service cutoffs, and the effects of slower-than-normal disconnection activity in general, offset by the amount subject to specific recovery under Missouri’s deferral order (see Note 4, Regulatory Matters). The accounts receivable of Spire’s non-utility businesses are evaluated separately from those of the Utilities. The allowance for credit losses for those other businesses is based on a continuous evaluation of the individual counterparty risk and is not significant for the periods presented. Activity in the allowance for credit losses for the three and six months ended March 31, 2021, is shown in the following table.

| Three Months Ended March 31, 2021 |  |  | Six Months Ended March 31, 2021 |
|  |  |  |  | Spire |  |  | Spire |  |  |  |  |  |  | Spire |  |  | Spire |

NEW ACCOUNTING PRONOUNCEMENTS – In June 2016, the FASB issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments, which was later supplemented by ASU Nos. 2018-19, 2019-04, 2019-05 and 2019-11. The new standard replaces the current “incurred loss” model with an “expected loss” model for certain instruments, including trade receivables, requiring measurement of all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. It also required entities to record credit loss allowances for available-for-sale securities rather than impair the carrying amount of the securities. Spire, Spire Missouri and Spire Alabama adopted the new standard for the quarter ended December 31, 2020. Based on the credit quality of the existing available-for-sale securities portfolio, no allowance for credit losses was recognized for those investments. Application of the new guidance did not result in any significant modifications to the Company’s policies related to recognizing an allowance on trade receivables, and the adoption of the new standard did not have a material impact on Spire’s, Spire Missouri’s and Spire Alabama’s financial statements.

RECLASSIFICATIONS – Spire’s consolidated statements of income historically showed Gas Utility operating revenues and expense line items separately from Gas Marketing and other operations. The current presentation shows operating revenues and expense line items on a consolidated basis. Disaggregated data is presented in Note 9, Information by Operating Segment. Prior period amounts have been reclassified to conform with the current period presentation.

Like all the Company’s regulatory assets, these regulatory assets are expected to be recovered from customers in future rates. The recovery period for the future income taxes due from customers and pension and other postretirement benefit costs could be 20 years or longer, based on current Internal Revenue Service guidelines and average remaining service life of active participants, respectively. The other items not earning a return are expected to be recovered over a period not to exceed 15 years, consistent with precedent set by the MoPSC. Spire Alabama does not have any regulatory assets that are not earning a return.

On March 7, 2018, the MoPSC issued its order in two general rate cases (docketed as GR-2017-0215 and GR-2017-0216), approving new tariffs that became effective on April 19, 2018. Certain provisions of the order allow less future recovery of certain deferred or capitalized costs than estimated based upon previous rate proceedings, and management determined that the related regulatory assets should be written down or off in connection with the preparation of the financial statements for the second quarter of 2018. Spire Missouri filed an appeal of portions of the MoPSC’s order, including the disallowance of certain pension costs ($28.8). On February 9, 2021, the Missouri Supreme Court issued its decision, reversing the MoPSC’s order with respect to certain pension costs and affirming the MoPSC’s order in all other respects. The case will now be remanded back to the MoPSC with directions that $9.0 in pension assets that accrued between 1994 and 1996 be added to the Company’s prepaid pension asset. The MoPSC has not yet opened a remand docket in the case, but based on the court’s decision, the Company increased its noncurrent regulatory asset for “Pension and postretirement benefit costs” and reduced operation and maintenance expense for the three and six months ended March 31, 2021. Like the original write-down in 2018, this adjustment is excluded for the net economic earnings financial measure.

In the first half of fiscal 2020, provisions totaling $4.2 were recorded to Spire Missouri’s regulatory liability for Infrastructure System Replacement Surcharge (ISRS) revenues related to customer billings recorded during the period under a disputed ISRS filing, along with a $0.6 provision for interest due on all ISRS revenues in dispute. The after-tax impact of these provisions reduced net income for the six months ended March 31, 2020, by $3.7, which was excluded for the net economic earnings financial measure. As previously disclosed, these matters were settled by the end of fiscal 2020.

In September 2020, Spire Missouri, the MoPSC staff and the OPC reached a Unanimous Stipulation and Agreement regarding Spire Missouri’s request for an Accounting Authority Order (AAO) pertaining to certain costs and lost customer fee revenue related to the COVID-19 pandemic. In October 2020, the MoPSC issued an order approving that agreement and granting an AAO effective through March 31, 2021. Accordingly, Spire Missouri recorded a net regulatory asset of $3.4 and $3.8 as of March 31, 2021, and September 30, 2020, respectively, related to the deferral of applicable costs and has tracked lost customer fee revenue. All ratemaking treatment of the deferrals and any revenue recoveries is reserved for consideration in Spire Missouri’s ongoing general rate case.

On December 11, 2020, Spire Missouri filed a general rate case with the MoPSC that includes new proposed rates for its service areas. The case proposes an increase in base rates, reflecting recovery of system investments and operating costs necessary to maintain the safety and reliability of its natural gas distribution systems as well as to support enhancements to customer service. The request, if approved, represents a net base rate increase of $64.2. Spire Missouri is already recovering $47.3 from customers through the ISRS, resulting in a total base rate increase request of $111.5. The ISRS cap would then be reset in order to continue the timely recovery of the investment in pipeline upgrades. The proposed rates are calculated on a filed rate base of $2,780 based on the end of fiscal year 2020, reflecting the significant investment made in infrastructure upgrades and other systems. Among other things, the filing changes rate design, proposes new customer programs, and aligns the tariffs of the company’s service areas. The filing assumes a common equity ratio of 54.25% and a 9.95% return on equity. Management anticipates that certain measures, such as rate base, capital structure and operating costs will be updated through May 31, 2021. In accordance with Missouri law, the MoPSC has up to 11 months to consider this filing. Direct testimony of other parties is due to be filed in May 2021, local public hearings will take place June 21–25, 2021, and evidentiary hearings are scheduled for late July and early August 2021.

In mid-February 2021, the central U.S. experienced a period of unusually severe cold weather, and Spire Missouri implemented an Operational Flow Order (OFO) to preserve the integrity of its distribution system. During this time, Spire Missouri was required to purchase additional natural gas supply, both to ensure adequate supply for its firm utility customers, and to cover the shortfall created when third-party marketers failed to deliver natural gas supply to its city gates on behalf of their customers. In accordance with its tariffs, Spire Missouri invoiced the cost of gas and associated penalties totaling $195.8 to non-compliant marketers pursuant to the MoPSC-approved OFO tariff. Recoveries collected will be an offset to cost of natural gas for firm utility customers through the Purchased Gas Adjustment (PGA) and Actual Cost Adjustment. The three largest counterparties did not remit payment when due, so Spire Missouri filed suit against them in federal court to recover the invoiced amounts. The marketers have filed complaints with the MoPSC requesting review of the transactions between them and Spire; at this time, the Company has no reason to believe the MoPSC will not follow the tariff and has determined collection is probable. The MoPSC has also opened a working case to investigate the effects of the February cold weather event on all Missouri utilities. Spire Missouri is not subject to any upstream OFO penalties on any interstate pipelines.

Spire Missouri is able to sell excess natural gas supply and capacity to third parties off system, resulting in significant savings to its firm utility customers through the gas incentive mechanisms of its PGA. Spire Missouri normally retains 25% and passes 75% through to its customers. During the February cold weather event, Spire Missouri had an unusually large off-system sale resulting in $100.0 of incremental gross revenue. Due to the nature and magnitude of this particular transaction, Spire Missouri anticipates distributing all or a portion of its usual 25% share to customers and plans to work with the MoPSC and community partners over the rest of the fiscal year to determine the method and timing. Accordingly, a $25.0 regulatory liability has been recorded, with a corresponding reduction in revenue.

Spire Missouri’s net deferred gas costs and average inventory cost in the quarter increased by approximately $110 primarily due to the February weather event, including projected offsets of off-system sales and tariff-based OFO penalties.

In August 2018, the Federal Energy Regulatory Commission (FERC) approved an order issuing a Certificate of Public Convenience and Necessity for the Spire STL Pipeline (“August 2018 Order”), and in November 2018, the FERC issued a Notice to Proceed, allowing construction to begin. In November 2019, Spire STL Pipeline received FERC authorization to place the pipeline into service. Also, in November 2019, the FERC issued an Order on Rehearing of the August 2018 Order dismissing or denying the outstanding requests for rehearing filed by several parties, dismissing the request for stay filed by one party, and noting the withdrawal of the request for rehearing by another party. On January 21, 2020, two of the rehearing parties filed petitions for review of the FERC’s orders with the U.S. Court of Appeals for the District of Columbia Circuit. Spire STL Pipeline and Spire Missouri have intervened and filed responsive briefs in this proceeding, which remains pending.

On October 9, 2020, Spire Storage filed with the FERC an Abbreviated Application for an Amendment of Certificate of Public Convenience and Necessity, Reaffirmation of Market-Based Rate Authority, and Related Authorizations pursuant to Section 7(c) of the Natural Gas Act. The application, which requests authorization to expand capacity and increase pipeline connectivity at certain of Spire Storage’s natural gas storage facilities in Wyoming, remains pending.

5. FINANCING

Short-term

Spire, Spire Missouri and Spire Alabama have a syndicated revolving credit facility pursuant to a loan agreement with 11 banks, expiring October 31, 2023. The loan agreement has an aggregate credit commitment of $975.0, including sublimits of $300.0 for Spire, $475.0 for Spire Missouri, and $200.0 for Spire Alabama. These sublimits may be reallocated from time to time among the three borrowers within the $975.0 aggregate commitment, with commitments fees applied for each borrower relative to its credit rating. Spire may use its line to provide for the funding needs of various subsidiaries. The agreement also contains financial covenants limiting each borrower’s consolidated total debt, including short-term debt, to no more than 70% of its total capitalization. As defined in the line of credit, on March 31, 2021, total debt was less than 60% of total capitalization for each borrower.

Spire has a commercial paper program (“CP Program”) pursuant to which Spire may issue short-term, unsecured commercial paper notes. Amounts available under the CP Program may be borrowed, repaid and re-borrowed from time to time, with the aggregate face or principal amount of the notes outstanding under the CP Program at any time not to exceed $975.0. The notes may have maturities of up to 365 days from date of issue.

On March 26, 2020, Spire entered into a loan agreement with two banks providing for a term loan of $150.0, which was immediately fully funded. It was repaid on December 16, 2020. The term loan bore interest at the LIBOR Rate (as defined in the loan agreement) plus 0.85% per annum.

On March 23, 2021, Spire Missouri entered into a loan agreement with several banks for a $250.0, 364-day unsecured term loan with an interest rate based on LIBOR plus 65 basis points. The loan carries no prepayment penalty and has the same covenants as the revolving credit facility.

Information about Spire’s consolidated short-term borrowings and about Spire Missouri’s and Spire Alabama’s borrowings from Spire is presented in the following table. As of March 31, 2021, $398.1 of Spire’s short-term borrowings were used to support lending to the Utilities.

Long-term Debt

The long-term debt agreements of Spire, Spire Missouri and Spire Alabama contain customary financial covenants and default provisions. As of March 31, 2021, there were no events of default under these financial covenants.

Interest expense shown on Spire’s consolidated statements of income and Spire Missouri’s statements of comprehensive income is net of the capitalized interest amounts shown in the following table.

|  | Three Months Ended March 31, |  |  | Six Months Ended March 31, |
|  | 2021 |  |  | 2020 |  |  | 2021 |  |  | 2020 |

On December 15, 2020, Spire Alabama issued and sold to certain institutional investors in a private placement $150.0 of 2.04% Series 2020 Senior Notes due December 15, 2030. Interest is payable semi-annually. The notes are senior unsecured obligations of Spire Alabama and rank equal in right to payment with all its other senior unsecured indebtedness. Spire Alabama used the proceeds to repay short-term debt.

In February 2021, Spire issued $175.0 of 2021 Series A 0.75% Remarketable Senior Notes as part of the equity units described in the next section.

Equity Units

In February 2021, Spire issued 3.5 million equity units, initially in the form of Corporate Units, for an aggregate stated amount of $175.0, resulting in net proceeds (after underwriting fees and other issuance costs) of $169.3. Each “Corporate Unit” has a stated amount of fifty dollars and consists of (i) a stock purchase contract and (ii) a 1/20, or 5%, undivided beneficial ownership interest in one thousand dollars principal amount of Spire’s 2021 Series A 0.75% Remarketable Senior Notes due March 1, 2026 (RSNs). The RSNs are pledged as collateral to secure the holder’s obligation under the related stock purchase contracts. Each stock purchase contract obligates the holder to purchase, and Spire to issue and deliver, on March 1, 2024, for a price of fifty dollars in cash, a variable number of shares of its common stock as follows (subject to anti-dilution adjustments).

If the applicable market value* per share of Spire common stock is: |  | Number of shares to be purchased per stock purchase contract is:
Equal to or greater than $78.6906 (“threshold appreciation price”) |  | 0.6354 (“minimum settlement rate”)
Less than $78.6906, but greater than $64.24 |  | $50.00 ÷ applicable market value*
Less than or equal to $64.24 (“reference price”) |  | 0.7783 (“maximum settlement rate”)

*Based on the volume-weighted average price of Spire common stock during the 20 trading days before settlement.

If a holder elects to settle purchase contracts early, the holder would pay fifty dollars per unit and receive 0.6354 shares per unit.

The Company will make quarterly interest payments on the RSNs at the rate of 0.75% per year and quarterly contract adjustment payments on the stock purchase contracts at the rate of 6.75%. The RSNs and the contract adjustment payments are structurally subordinated to all liabilities of Spire’s subsidiaries.

The Company has recorded the $35.0 present value of the stock purchase contract payments as a liability (reflected in “Other” current and noncurrent liabilities on the balance sheet) offset by a charge to additional paid-in capital in equity. This noncash financing activity has been excluded from the statement of cash flows. Interest payments on the RSNs are recorded as interest expense and stock purchase contract payments are charged against the liability. Accretion of the stock purchase contract liability is recorded as imputed interest expense. In calculating diluted EPS, the Company applies the treasury stock method to the Corporate Units. These securities have not had an effect on diluted EPS.

In order to secure funds necessary for the holders to pay the purchase price of the common stock on the purchase contract settlement date, the remarketing agent will remarket the RSNs on behalf of the current holders to new third-party investors. Following any successful remarketing of the RSNs, the interest rate on the RSNs will be reset, interest will be payable on a semi-annual basis, and Spire will cease to have the option to redeem the RSNs, other than in connection with the occurrence or continuance of certain special events.

6. FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts of cash and cash equivalents, notes receivable, and short-term debt approximate fair value due to the short maturity of these instruments. The fair values of long-term debt are estimated based on market prices for similar issues. Refer to Note 7, Fair Value Measurements, for information on financial instruments measured at fair value on a recurring basis.

The carrying amounts and estimated fair values of financial instruments not measured at fair value on a recurring basis are shown in the following tables, classified according to the fair value hierarchy. There were no such instruments classified as Level 3 (significant unobservable inputs) as of March 31, 2021, September 30, 2020, and March 31, 2020.

7. FAIR VALUE MEASUREMENTS

The information presented below categorizes the assets and liabilities in the balance sheets that are accounted for at fair value on a recurring basis in periods subsequent to initial recognition.

The mutual funds included in Level 1 are valued based on exchange-quoted market prices of individual securities.

Derivative instruments included in Level 1 are valued using quoted market prices on the New York Mercantile Exchange (NYMEX) or the Intercontinental Exchange (ICE). Derivative instruments classified in Level 2 include physical commodity derivatives that are valued using broker or dealer quotation services whose prices are derived principally from, or are corroborated by, observable market inputs. Also included in Level 2 are certain derivative instruments that have values that are similar to, and correlate with, quoted prices for exchange-traded instruments in active markets. Derivative instruments included in Level 3 are valued using generally unobservable inputs that are based upon the best information available and reflect management’s assumptions about how market participants would price the asset or liability. There were no Level 3 balances as of March 31, 2021, and those Level 3 balances at September 30, 2020, and March 31, 2020, consisted of gas commodity contracts. The Company’s and the Utilities’ policy is to recognize transfers between the levels of the fair value hierarchy, if any, as of the beginning of the interim reporting period in which circumstances change or events occur to cause the transfer.

The mutual funds are included in “Other Investments” on the Company’s balance sheets and in “Other Property and Investments” on Spire Missouri’s balance sheets. Derivative assets and liabilities, including receivables and payables associated with cash margin requirements, are presented net in the balance sheets when a legally enforceable netting agreement exists between the Company, Spire Missouri, or Spire Alabama and the counterparty to a derivative contract.

8. PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

Spire and the Utilities maintain pension plans for their employees.

Spire Missouri has non-contributory, defined benefit, trusteed forms of pension plans covering the majority of its employees. Plan assets consist primarily of corporate and U.S. government obligations and a growth segment consisting of exposure to equity markets, commodities, real estate and inflation-indexed securities, achieved through derivative instruments.

Spire Alabama has non-contributory, defined benefit, trusteed forms of pension plans covering the majority of its employees. Qualified plan assets are comprised of mutual and commingled funds consisting of U.S. equities with varying strategies, global equities, alternative investments, and fixed income investments.

The net periodic pension cost includes components shown in the following tables. The components other than the service costs and regulatory adjustment are presented in “Other Income (Expense), Net” in the income statement, except for Spire Alabama’s losses on lump-sum settlements. Such losses are capitalized in regulatory balances and amortized over the remaining actuarial life of individuals in the plan, and that amortization is presented in “Other Income (Expense), Net.”

Pursuant to the provisions of Spire Missouri’s and Spire Alabama’s pension plans, pension obligations may be satisfied by monthly annuities, lump-sum cash payments, or special termination benefits. Lump-sum payments are recognized as settlements (which can result in gains or losses) only if the total of such payments exceeds the sum of service and interest costs in a specific year. Special termination benefits, when offered, are also recognized as settlements which can result in gains or losses. For the three and six months ended March 31, 2021, one Alabama plan met the criteria for settlement recognition. The lump-sum payments recognized as settlements for the remeasurement were $12.9. The lump-sum settlement resulted in a loss of $3.8. For the remeasurement, the discount rate for the Alabama plan was updated to 3.2% from 2.95% at September 30, 2020. The Alabama regulatory tariff requires that settlement losses be amortized over the remaining actuarial life of the individuals in the plan— in this case, 11.4 years. Therefore, no lump sum settlement expense was recorded in the period ended March 31, 2021. In the quarter ended March 31, 2020, two Spire Missouri plans met the criteria for settlement recognition. The lump-sum payments recognized as settlements for the remeasurement were $59.1. The lump-sum settlement resulted in a loss of $21.0. For the remeasurements, the discount rates for the Missouri plans were updated to 2.85% from 3.2% at September 30, 2019.

The funding policy of the Utilities is to contribute an amount not less than the minimum required by government funding standards, nor more than the maximum deductible amount for federal income tax purposes. Fiscal 2021 contributions to Spire Missouri’s pension plans through March 31, 2021 were $28.3 to the qualified trusts and none to non-qualified plans. There were $4.5 of fiscal 2021 contributions to the Spire Alabama pension plans through March 31, 2021.

Contributions to the qualified trusts of Spire Missouri’s pension plans for the remainder of fiscal 2021 are anticipated to be $13.7. Contributions to Spire Alabama’s pension plans for the remainder of fiscal 2021 are anticipated to be $6.6.

Other Postretirement Benefits

Spire and the Utilities provide certain life insurance benefits at retirement. Spire Missouri plans provide for medical insurance after early retirement until age 65. For retirements prior to January 1, 2015, certain Spire Missouri plans provided medical insurance after retirement until death. The Spire Alabama plans provide medical insurance upon retirement until death for certain retirees depending on the type of employee and the date the employee was originally hired.

The net periodic postretirement benefit cost includes components shown in the following tables. The components other than the service costs and regulatory adjustment are presented in “Other Income (Expense), Net” in the income statement, except in the event Spire Alabama incurs losses on lump-sum settlements. Any such losses are capitalized in regulatory balances and amortized over the remaining actuarial life of individuals in the plan, and that amortization is presented in “Other Income (Expense), Net.”

Missouri and Alabama state laws provide for the recovery in rates of costs accrued pursuant to GAAP provided that such costs are funded through an independent, external funding mechanism. The Utilities have established Voluntary Employees’ Beneficiary Association (VEBA) and Rabbi Trusts as external funding mechanisms. The assets of the VEBA and Rabbi Trusts consist primarily of money market securities and mutual funds invested in stocks and bonds.

The Utilities’ funding policy is to contribute amounts to the trusts equal to the periodic benefit cost calculated pursuant to GAAP as recovered in rates. There have been no contributions to the postretirement plans through March 31, 2021 for Spire Missouri or Spire Alabama, and none are expected to be required for the remainder of the fiscal year.

9. INFORMATION BY OPERATING SEGMENT

The Company has two reportable segments: Gas Utility and Gas Marketing. The Gas Utility segment is the aggregation of the operations of the Utilities. The Gas Marketing segment includes the results of Spire Marketing, a subsidiary engaged in the non-regulated marketing of natural gas and related activities, including utilizing natural gas storage contracts for providing natural gas sales. Other components of the Company’s consolidated information include:

| • | unallocated corporate items, including certain debt and associated interest costs;

| • | Spire STL Pipeline, a subsidiary of Spire providing interstate natural gas pipeline transportation services;

| • | Spire Storage, a subsidiary of Spire providing interstate natural gas storage services; and

| • | Spire’s subsidiaries engaged in the operation of a propane pipeline, the compression of natural gas, and risk management, among other activities.

Accounting policies are described in Note 1, Summary of Significant Accounting Policies. Intersegment transactions include sales of natural gas from Spire Marketing to Spire Missouri, Spire Alabama and Spire Storage, sales of natural gas from Spire Missouri and Spire Alabama to Spire Marketing, propane transportation services provided by Spire NGL Inc. to Spire Missouri, and propane storage services provided by Spire Missouri to Spire NGL Inc.

Management evaluates the performance of the operating segments based on the computation of net economic earnings. Net economic earnings exclude from reported net income the after-tax impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisition, divestiture and restructuring activities, and the largely non-cash impacts of impairments and other non-recurring or unusual items such as certain regulatory, legislative, or GAAP standard-setting actions.

10. COMMITMENTS AND CONTINGENCIES

Commitments

The Company and the Utilities have entered into contracts with various counterparties, expiring on dates through 2039, for the storage, transportation, and supply of natural gas. Minimum payments required under the contracts in place at March 31, 2021, are estimated at $1,632.2, $1,264.6, and $244.7 for the Company, Spire Missouri, and Spire Alabama, respectively. Additional contracts are generally entered into prior to or during the heating season of November through April. The Utilities recover their costs from customers in accordance with their PGA clauses or GSA riders.

Contingencies

The Company and the Utilities account for contingencies, including environmental liabilities, in accordance with accounting standards under the loss contingency guidance of ASC Topic 450, Contingencies, when it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

In addition to matters noted below, the Company and the Utilities are involved in other litigation, claims, and investigations arising in the normal course of business. Management, after discussion with counsel, believes the final outcome will not have a material effect on the statements of income, balance sheets, and statements of cash flows of the Company, Spire Missouri, or Spire Alabama. However, there is uncertainty in the valuation of pending claims and prediction of litigation results.

The Company and the Utilities own and operate natural gas distribution, transmission, and storage facilities, the operations of which are subject to various environmental laws, regulations, and interpretations. While environmental issues resulting from such operations arise in the ordinary course of business, such issues have not materially affected the Company’s or Utilities’ financial position and results of operations. As environmental laws, regulations, and their interpretations change, the Company or the Utilities may incur additional environmental liabilities that may result in additional costs, which may be material.

In the natural gas industry, many gas distribution companies have incurred environmental liabilities associated with sites they or their predecessor companies formerly owned or operated where manufactured gas operations took place. The Utilities each have former manufactured gas plant (MGP) operations in their respective service territories, some of which are discussed under the Spire Missouri and Spire Alabama headings below. To the extent costs are incurred associated with environmental remediation activities, the Utilities would request authority from their respective regulators to defer such costs (less any amounts received from insurance proceeds or as contributions from other potentially responsible parties (PRPs)) and collect them through future rates.

To date, costs incurred for all Spire MGP sites for investigation, remediation and monitoring have not been material. However, the amount of costs relative to future remedial actions at these and other sites is unknown and may be material. The actual future costs that Spire Missouri and Spire Alabama may incur could be materially higher or lower depending upon several factors, including whether remediation will be required, final selection and regulatory approval of any remedial actions, changing technologies and government regulations, the ultimate ability of other PRPs to pay, and any insurance recoveries.

In 2020, Spire retained an outside consultant to conduct probabilistic cost modeling of its former MGP sites in Missouri and Alabama. The purpose of this analysis was to develop an estimated range of probabilistic future liability for each of their MGP sites. That analysis, completed in March 2021, provided a range of demonstrated possible future expenditures to investigate, monitor and remediate the former MGP sites. Spire Missouri and Spire Alabama have recorded their best estimates of the probable expenditures that relate to these matters. The amount remains immaterial, and Spire Missouri, Spire Alabama and the Company do not expect potential liabilities that may arise from remediating these sites to have a material impact on their future financial condition or results of operations.

42

Spire Missouri

Spire Missouri has identified three former MGP sites in the city of St. Louis, Missouri (the “City”) where costs have been incurred and claims have been asserted. Spire Missouri has enrolled two of the sites in the Missouri Department of Natural Resources (MDNR) Brownfields/Voluntary Cleanup Program (BVCP). The third site is the result of a relatively new claim assertion by the United States Environmental Protection Agency (EPA).

In conjunction with redevelopment of one of the sites, Spire Missouri and another former owner of the site entered into an agreement (the “Remediation Agreement”) with the City development agencies, the developer, and an environmental consultant that obligates one of the City agencies and the environmental consultant to remediate the site and obtain a No Further Action letter from the MDNR. The Remediation Agreement also provides for a release of Spire Missouri and the other former site owner from certain liabilities related to the past and current environmental condition of the site and requires the developer and the environmental consultant to maintain certain insurance coverage, including remediation cost containment, premises pollution liability, and professional liability. The operative provisions of the Remediation Agreement were triggered on December 20, 2010, on which date Spire Missouri and the other former site owner, as full consideration under the Remediation Agreement, paid a small percentage of the cost of remediation of the site.

Spire Missouri has not owned the second site for many years. In a letter dated June 29, 2011, the Attorney General for the State of Missouri informed Spire Missouri that the MDNR had completed an investigation of the site. The Attorney General requested that Spire Missouri participate in the follow up investigations of the site. In a letter dated January 10, 2012, Spire Missouri stated that it would participate in future environmental response activities at the site in conjunction with other PRPs that are willing to contribute to such efforts in a meaningful and equitable fashion. Accordingly, Spire Missouri entered into a cost sharing agreement for remedial investigation with other PRPs. To date, MDNR has not approved the agreement, so remedial investigation has not yet occurred.

Additionally, in correspondence dated November 30, 2016, Region 7 of the EPA has asserted that Spire Missouri is liable under Section 107(a) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) for alleged coal gas waste contamination at a third site in the northern portion of the City on which Spire Missouri operated a MGP. Spire Missouri has not owned or operated the site (also known as Station “B”) for over 70 years. Spire Missouri and the site owner have met with the EPA and reviewed its assertions. Both Spire Missouri and the site owner have notified the EPA that information and data provided by the EPA to date does not rise to the level of documenting a threat to the public health or environment. As such, Spire Missouri requested more information from the EPA, some of which would also be utilized to identify other former owners and operators of the site that could be added as PRPs. To date, Spire Missouri has not received a response from the EPA.

Spire Missouri has notified its insurers that it seeks reimbursement for costs incurred in the past and future potential liabilities associated with these MGP sites. While some of the insurers have denied coverage and reserved their rights, Spire Missouri retains the right to seek potential reimbursements from them.

On March 10, 2015, Spire Missouri received a Section 104(e) information request under CERCLA from EPA Region 7 regarding the former Thompson Chemical/Superior Solvents site in the City. In turn, Spire Missouri issued a Freedom of Information Act (FOIA) request to the EPA on April 3, 2015, in an effort to identify the basis of the inquiry. The FOIA response from the EPA was received on July 15, 2015, and a response was provided to the EPA on August 15, 2015. Spire Missouri has received no further inquiry from the EPA regarding this matter.

43

In its western service area, Spire Missouri has six owned MGP sites enrolled in the BVCP, including Joplin MGP #1, St. Joseph MGP #1, Kansas City Coal Gas Station B, Kansas City Station A Railroad area, Kansas City Coal Gas Station A, and Independence MGP #2. Source removal has been conducted at all of the owned sites since 2003 with the exception of Joplin. On September 15, 2016, a request was made with the MDNR for a restrictive covenant use limitation with respect to Joplin. Remediation efforts at the six sites are at various stages of completion, ranging from groundwater monitoring and sampling following source removal activities to the aforementioned request in respect to Joplin. As part of its participation in the BVCP, Spire Missouri communicates regularly with the MDNR with respect to its remediation efforts and monitoring activities at these sites. On May 11, 2015, MDNR approved the next phase of investigation at the Kansas City Station A and Railroad areas.

Spire Alabama

Spire Alabama is in the chain of title of nine former MGP sites, four of which it still owns, and five former manufactured gas distribution sites, one of which it still owns.

In 2012, Spire Alabama responded to an EPA Request for Information Pursuant to Section 104 of CERCLA relating to the 35th Avenue Superfund Site located in North Birmingham, Jefferson County, Alabama. Spire Alabama was identified as a PRP under CERCLA for the cleanup of the site or costs the EPA incurs in cleaning up the site. At this point, Spire Alabama has not been provided information that would allow it to determine the extent, if any, of its potential liability with respect to the 35th Avenue Superfund Site and vigorously denies its inclusion as a PRP.

Spire

In addition to those discussed above for Spire Missouri and Spire Alabama, Spire is aware of the following contingent matters.

Spire Marketing, along with many natural gas industry participants, faced the unprecedented effects of the February 2021 cold weather event. Numerous natural gas producers and midstream operators were unable to deliver natural gas to market as they experienced wellhead freeze-offs, power outages and equipment failure from the extreme weather. These events resulted in supply curtailments, and related notices of force majeure to excuse performance, from and to certain counterparties. Further, these events have made Spire Marketing subject to various commercial disputes (including regarding force majeure) and a regulatory dispute regarding tariff obligations as a shipper on an interstate pipeline. As such, Spire Marketing has recorded an estimate of potential liabilities for damages based on communications with counterparties to date and the facts and circumstances surrounding each transaction. It is expected that the estimate will change as new facts emerge or settlements are reached, and it is possible that final settlement amounts may materially differ from the current estimate.

In February 2018, the Company was made aware of a complaint filed with the U.S. Department of Housing and Urban Development (HUD) by the South Alabama Center for Fair Housing and the National Community Reinvestment Coalition. The complaint alleged that Spire Gulf discriminated against unspecified residents of Eight Mile, Alabama, on the basis of race in violation of the Fair Housing Act by failing to adequately address the odorant release that occurred in 2008. On December 2, 2020, HUD issued a determination that found no reasonable cause exists that Spire Gulf discriminated against residents in Eight Mile, Alabama.

Management’s Discussion and Analysis of Financial Condition and Results of Operations should be read in conjunction with the Company’s Condensed Consolidated Financial Statements, Spire Missouri’s and Spire Alabama’s Condensed Financial Statements, and the notes thereto.

OVERVIEW

The Company has two reportable segments: Gas Utility and Gas Marketing. Nearly all of Spire’s earnings are derived from its Gas Utility segment, which reflects the regulated activities of the Utilities. Due to the seasonal nature of the Utilities’ business and the Spire Missouri rate design, earnings of Spire and each of the Utilities are typically concentrated during the heating season of November through April each fiscal year.

Gas Utility - Spire Missouri

Spire Missouri is Missouri’s largest natural gas distribution utility and is regulated by the MoPSC. Spire Missouri serves St. Louis, Kansas City, and other areas throughout the state. Spire Missouri purchases natural gas in the wholesale market from producers and marketers and ships the gas through interstate pipelines into its own distribution facilities for sale to residential, commercial and industrial customers. Spire Missouri also transports gas through its distribution system for certain larger customers who buy their own gas on the wholesale market. Spire Missouri delivers natural gas to customers at rates and in accordance with tariffs authorized by the MoPSC. The earnings of Spire Missouri are primarily generated by the sale of heating energy.

Gas Utility - Spire Alabama

Spire Alabama is the largest natural gas distribution utility in the state of Alabama and is regulated by the APSC. Spire Alabama’s service territory is located in central and northern Alabama. Among the cities served by Spire Alabama are Birmingham, the center of the largest metropolitan area in the state, and Montgomery, the state capital. Spire Alabama purchases natural gas through interstate and intrastate suppliers and distributes the purchased gas through its distribution facilities for sale to residential, commercial, and industrial customers, and other end-users of natural gas. Spire Alabama also transports gas through its distribution system for certain large commercial and industrial customers for a transportation fee. Effective December 1, 2020, for most of these transportation service customers, Spire Alabama also purchases gas on the wholesale market for sale to the customer upon delivery to the Spire Alabama distribution system. All Spire Alabama services are provided to customers at rates and in accordance with tariffs authorized by the APSC.

Gas Utility - Spire EnergySouth

Spire Gulf and Spire Mississippi are utilities engaged in the purchase, retail distribution and sale of natural gas to approximately 100,000 customers in southern Alabama and south-central Mississippi. Spire Gulf is regulated by the APSC, and Spire Mississippi is regulated by the MSPSC.

46

Gas Marketing

Spire Marketing is engaged in the marketing of natural gas and related activities on a non-regulated basis and is reported in the Gas Marketing segment. Spire Marketing markets natural gas across the central and southern U.S. It holds firm transportation and storage contracts in order to effectively manage its transactions with counterparties, which primarily include producers, municipalities, electric and gas utility companies, and large commercial and industrial customers.

Other

Other components of the Company’s consolidated information include:

| • | unallocated corporate items, including certain debt and associated interest costs;

| • | Spire STL Pipeline LLC (“Spire STL Pipeline”) and Spire Storage West LLC (“Spire Storage”), described below; and

| • | Spire’s subsidiaries engaged in the operation of a propane pipeline, the compression of natural gas, and risk management, among other activities.

Spire STL Pipeline is a wholly owned subsidiary of Spire which owns and operates a 65-mile pipeline connecting the Rockies Express Pipeline in Scott County, Illinois, to delivery points in St. Louis County, Missouri, including Spire Missouri’s storage facility. The pipeline is under the jurisdiction of the FERC and is capable of delivering up to 400,000 million British thermal units (MMBtu) per day of natural gas into eastern Missouri. Spire Missouri is the foundation shipper with a contractual commitment of 350,000 MMBtu per day. The pipeline was primarily constructed during fiscal 2019 and was placed into service in November 2019.

Spire Storage is engaged in the storage of natural gas in the western region of the United States. The facility consists of two storage fields operating under one FERC market-based rate tariff.

COVID-19

The outbreak of the novel coronavirus (COVID-19) has adversely impacted economic activity and conditions worldwide. We are continuing to assess the developments involving our workforce, customers and suppliers, as well as the response of federal and state authorities, our regulators and other business and community leaders. The Company has implemented what we believe to be appropriate procedures and protocols to ensure the safety of our customers, suppliers and employees. These actions include activating incident management procedures, work-from-home for our office-based employees, limiting direct contact with our customers, and suspending disconnections and late payment fees for our utility customers for several months in 2020.

We have experienced impacts on our results of operations from COVID-19, including:

| • | lost late payment fees due to a moratorium from late March through mid-June 2020;

| • | minor net margin impact from lower commercial and industrial volumes offset by additional residential fixed charges;

| • | bad debt expense increases due to additional expected credit losses on accounts receivable balances; and

| • | net other direct cost reductions due to lower travel, meals and entertainment and training offset by increased costs for enhanced cleaning and personal protective equipment for our facilities and field personnel compared to normal and expected levels.

Spire Missouri received an Accounting Authority Order from the MoPSC to defer certain costs through March 31, 2021, and has recorded a related net regulatory asset of $3.4 and $3.8 as of March 31, 2021, and September 30, 2020, respectively. Even with the cost increases and lost revenues, Spire Alabama exceeded the allowed return and recorded a Rate Stabilization and Equalization giveback in September 2020 and in January 2021, so there was no bottom-line impact of these COVID-19 effects.

47

An extended slowdown of the United States' economy, changes in commodity costs and/or significant changes in policy and regulation could result in lower demand for natural gas as well as negatively impact the ability of our customers, contractors, suppliers and other business partners to remain in business or return to operating health. These could have a material adverse effect on our results of operations, financial condition, liquidity and prospects.

The Company is participating in the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) provisions allowing for a payroll tax deferral which does not have an impact on our results of operations but defers the payment of the Company’s portion of certain payroll taxes until later in fiscal 2021 and 2022. Although the Company does not currently expect to seek relief under any other CARES Act provisions, we will continue to monitor all pending and future federal, state and local efforts related to the COVID-19 health crisis and assess our need and, as applicable, eligibility for any such relief.

NON-GAAP MEASURES

Net income, earnings per share and operating income reported by Spire, Spire Missouri and Spire Alabama are determined in accordance with accounting principles generally accepted in the United States of America (GAAP). Spire, Spire Missouri and Spire Alabama also provide the non-GAAP financial measures of net economic earnings, net economic earnings per share and contribution margin. Management and the Board of Directors use non-GAAP financial measures, in addition to GAAP financial measures, to understand and compare operating results across accounting periods, for financial and operational decision making, for planning and forecasting, to determine incentive compensation and to evaluate financial performance. These non-GAAP operating metrics should not be considered as alternatives to, or more meaningful than, the related GAAP measures. Reconciliations of non-GAAP financial measures to the most directly comparable GAAP measures are provided on the following pages.

Net Economic Earnings and Net Economic Earnings Per Share

Net economic earnings and net economic earnings per share are non-GAAP measures that exclude from net income the impacts of fair value accounting and timing adjustments associated with energy-related transactions, the impacts of acquisition, divestiture and restructuring activities, and the largely non-cash impacts of impairments and other non-recurring or unusual items such as certain regulatory, legislative or GAAP standard-setting actions. In addition, net economic earnings per share would exclude the impact, in the fiscal year of issuance, of any shares issued to finance acquisitions that have yet to be included in net economic earnings.

The fair value and timing adjustments are made in instances where the accounting treatment differs from what management considers the economic substance of the underlying transaction, including the following:

| • | Net unrealized gains and losses on energy-related derivatives that are required by GAAP fair value accounting associated with current changes in the fair value of financial and physical transactions prior to their completion and settlement. These unrealized gains and losses result primarily from two sources:

| 1) | changes in the fair values of physical and/or financial derivatives prior to the period of settlement; and

| 2) | ineffective portions of accounting hedges, required to be recorded in earnings prior to settlement, due to differences in commodity price changes between the locations of the forecasted physical purchase or sale transactions and the locations of the underlying hedge instruments;

| • | Lower of cost or market adjustments to the carrying value of commodity inventories resulting when the net realizable value of the commodity falls below its original cost, to the extent that those commodities are economically hedged; and

| • | Realized gains and losses resulting from the settlement of economic hedges prior to the sale of the physical commodity.

48

These adjustments eliminate the impact of timing differences and the impact of current changes in the fair value of financial and physical transactions prior to their completion and settlement. Unrealized gains or losses are recorded in each period until being replaced with the actual gains or losses realized when the associated physical transactions occur. Management believes that excluding the earnings volatility caused by recognizing changes in fair value prior to settlement and other timing differences associated with related purchase and sale transactions provides a useful representation of the economic effects of only the actual settled transactions and their effects on results of operations. While management uses these non-GAAP measures to evaluate all of its businesses, the net effect of these fair value and timing adjustments on the Utilities’ earnings is minimal because gains or losses on their natural gas derivative instruments are deferred pursuant to state regulation.

Contribution Margin

In addition to operating revenues and operating expenses, management also uses the non-GAAP measure of contribution margin when evaluating results of operations. Contribution margin is defined as operating revenues less natural gas costs and gross receipts tax expense. The Utilities pass to their customers (subject to prudence review by, as applicable, the MoPSC, APSC or MSPSC) increases and decreases in the wholesale cost of natural gas in accordance with their PGA clauses or GSA riders. The volatility of the wholesale natural gas market results in fluctuations from period to period in the recorded levels of, among other items, revenues and natural gas cost expense. Nevertheless, increases and decreases in the cost of gas associated with system gas sales volumes and gross receipts tax expense (which are calculated as a percentage of revenues), with the same amount (excluding immaterial timing differences) included in revenues, have no direct effect on operating income. Therefore, management believes that contribution margin is a useful supplemental measure, along with the remaining operating expenses, for assessing the Company’s and the Utilities’ performance.

Consolidated

Spire had net income of $187.4 for the three months ended March 31, 2021, compared with net income of $133.6 for the three months ended March 31, 2020. Diluted income per share of $3.55 for the current year quarter compared to $2.54 diluted income per share for the prior year quarter. The net income growth of $53.8 was driven by an $28.2 increase in Gas Marketing segment and a $24.1 increase in the Gas Utility segment. The Gas Marketing increase was the result of higher current year volume and margins, as a result of extreme weather and market conditions, as well as the monetization of storage positions. Gas Utility net income growth reflects the benefit of the Missouri Supreme Court ruling that partially reversed 2018 rate case pension cost disallowances totaling $9.0 ($6.8 after-tax), combined with higher volumes and ISRS revenues, and lower operating costs after removing the impact of the $19.1 transfer of year-over-year mix of service and nonservice postretirement benefit costs to other expense below the operating income line (the “Nonservice Cost Transfer”).

Spire’s net economic earnings were $195.6 ($3.71 per diluted share) for the three months ended March 31, 2021, an increase of $51.6 from the $144.0 ($2.75 per diluted share) reported for the same period in the prior year. The principal drivers of the increase in net economic earnings were higher Gas Marketing results combined with higher Gas Utility earnings, as reflected in the above table. These impacts are described in further detail below.

50

Gas Utility

For the three months ended March 31, 2021, net economic earnings for the Gas Utility segment increased $15.4 from the second quarter of the prior fiscal year, primarily due to a $9.9 increase at Spire Missouri and a $5.5 increase at Spire Alabama. Both Spire Missouri and Spire Alabama benefited from volume increases and higher off-system sales. Spire Missouri also benefited from higher ISRS revenues, customer growth, and lower Operations and Maintenance expense (O&M) after removing the impact of the Nonservice Cost Transfer, offset by $1.7 higher depreciation and amortization expense. Spire Alabama growth was also favorably impacted by net Rate Stabilization and Equalization (RSE) adjustments and lower O&M that offset higher depreciation and amortization expenses. These impacts are discussed in further detail below.

Gas Marketing

For the three months ended March 31, 2021, the net economic earnings for the Gas Marketing segment was $39.8, compared to net economic earnings of $5.1 in the three months ended March 31, 2020. The increase in the current-year period was a result of extreme market conditions due to the February 2021 cold weather event as well as asset optimization, including storage.

Other

For the three months ended March 31, 2021, net economic loss for Other decreased $1.5 compared with the second quarter of the prior fiscal year. The improvement primarily reflects better results from Spire Storage.

Consolidated

Spire reported operating revenue of $1,104.9 for the three months ended March 31, 2021, a $389.4 increase versus the prior year quarter. Both the Gas Utility and Gas Marketing segments experienced year-over-year increases in operating revenues. Spire’s contribution margin increased $63.1 compared with last year, with increases of $40.0 in the Gas Marketing segment, $22.0 for the Gas Utility segment, and $1.0 for Other (STL Pipeline and Spire Storage) all contributing to growth. Depreciation and amortization expenses were up $2.3 company-wide driven by a $2.5 increase in the Gas Utility segment. Gas Utility O&M expenses of $104.0 for the quarter were $10.9 lower than last year, after removing the $19.1 impact of the Nonservice Cost Transfer. These impacts are described in further detail below.

Gas Utility

Operating Revenues – Gas Utility operating revenues for the three months ended March 31, 2021, were $1,053.1, or $374.1 higher than the same period in the prior year. The increase in Gas Utility operating revenues was attributable to the following factors:

Spire Missouri and Spire Alabama – Higher PGA/GSA costs |  | $ | 208.0 |
Spire Missouri and Spire Alabama – Off-system sales and capacity release |  |  | 95.5 |
Spire Missouri and Spire Alabama – Volumetric usage (net of weather mitigation) |  |  | 49.6 |
Spire Missouri – ISRS (including prior year ISRS rulings provision true-up of $2.2) |  |  | 6.6 |
Spire Missouri and Spire Alabama – Higher gross-receipt taxes |  |  | 4.3 |
Spire Alabama – RSE adjustments, net |  |  | 4.1 |
All other factors |  |  | 6.0 |
Total Variation |  | $ | 374.1 |

The increase in revenues was primarily driven by higher gas volumes resulting in $208.0 higher gas costs (including $195.8 of cover charges and OFO penalties to certain wholesale customers), a $95.5 increase in off-system sales and capacity release (relating primarily to the February 2021 cold weather event), $49.6 positive impact of higher volumetric usage resulting from colder weather versus the prior year, primarily at Spire Missouri. The Utility segment also benefited from $6.6 growth in ISRS revenues (including the impact of reversing a prior-year charge of $2.2 related to the ISRS ruling settled later in the year), and $4.1 in net positive RSE adjustments at Spire Alabama.

Contribution Margin – Gas Utility contribution margin was $391.8 for the three months ended March 31, 2021, a $22.0 increase over the same period in the prior year. The increase was attributable to the following factors:

Spire Missouri and Spire Alabama – Volumetric usage (net of weather mitigation) |  | $ | 7.3 |
Spire Missouri – ISRS (including prior year ISRS rulings provision true-up of $2.2) |  |  | 6.6 |
Spire Alabama – RSE adjustments, net |  |  | 4.3 |
Spire Missouri and Spire Alabama – Off-system sales and capacity release |  |  | 2.1 |
All other factors |  |  | 1.7 |
Total Variation |  | $ | 22.0 |

The increase in contribution margin was primarily attributable to $7.3 favorable weather/volumetric impacts, Spire Missouri’s net ISRS amounts (including $2.2 prior-year true-up of charges for ISRS rulings) of $6.6, combined with $4.3 net favorable RSE adjustments at Spire Alabama, and $2.1 higher off-system sales, primarily due to the February 2021 cold weather events when compared to warmer temperatures last year.

Operating Expenses – O&M expenses for the three months ended March 31, 2021 were $1.9 lower than the prior year after removing the $19.1 impact of the Nonservice Cost Transfer and the reversal of $9.0 of previously disallowed pension expenses relating to the 2018 rate case due to a recent Missouri Supreme Court ruling. The decrease was largely due to lower costs in operations, administrative and employee-related expenses. Depreciation and amortization expenses for the three months ended March 31, 2021, were $2.5 higher than the same period in the prior year primarily driven by continued infrastructure capital expenditures across all the Utilities.

52

Gas Marketing

Operating Revenues – Operating revenues increased $0.1 versus the prior-year period as higher retail volumes and higher commodity prices were mostly offset by adjustments for certain retail customers.

Contribution Margin – Gas Marketing contribution margin during the three months ended March 31, 2021, increased $48.7 from the same period in the prior year. After consideration of $8.7 unfavorable change in derivative activity and fair value measurements which are excluded from net economic earnings, the reported variance was a $40.0 increase versus the same quarter in the prior year reflecting value realized from storage positions. These impacts were magnified due to the February 2021 cold weather event.

Spire Marketing, along with many natural gas industry participants, faced the unprecedented effects of the February 2021 cold weather event. Numerous natural gas producers and midstream operators were unable to deliver natural gas to market as they experienced wellhead freeze-offs, power outages and equipment failure from the extreme weather. These events resulted in supply curtailments, and related notices of force majeure to excuse performance, from and to certain counterparties. Further, these events have made Spire Marketing subject to various commercial disputes (including regarding force majeure) and a regulatory dispute regarding tariff obligations as a shipper on an interstate pipeline. As such, Spire Marketing has recorded an estimate of potential liabilities for damages based on communications with counterparties to date and the facts and circumstances surrounding each transaction. It is expected that the estimate will change as new facts emerge or settlements are reached, and it is possible that final settlement amounts may materially differ from the current estimate.

Interest Charges

Consolidated interest charges during the three months ended March 31, 2021, decreased by $1.4 from the same period in the prior year, principally due to lower rates on short-term borrowings. For the three months ended March 31, 2021 and 2020, average short-term borrowings were $626.7 and $544.2, respectively, and the average interest rates on these borrowings were 0.28% and 2.1%, respectively.

Income Taxes

Consolidated income tax for the three months ended March 31, 2021, increased $15.8 versus the same period in the prior year. The variance is due to higher pre-tax book income and the mix of earnings by source, which results in a higher effective tax rate in the current year.

53

Operating revenues for the three months ended March 31, 2021, increased $333.4 from the same period in the prior year primarily due by higher gas volumes resulting in $202.9 higher gas costs (including $195.8 of cover charges and OFO penalties to certain wholesale customers), a $94.3 increase related to higher off-system sales, combined with $24.8 in volumetric impacts (including weather mitigation), higher ISRS revenues of $6.6 and a $2.4 increase in gross receipts taxes.

Contribution margin for the three months ended March 31, 2021, increased $17.2 from the same period in the prior year, largely due to the $6.8 increase attributable to volumetric impacts (including weather mitigation), combined with the $6.6 increase in ISRS mentioned above and $1.4 higher off-system sales.

O&M expenses for the three months ended March 31, 2021, increased $12.0 versus the prior year quarter. After removing the $19.7 year-over-year impact of the Nonservice Cost Transfer, O&M was $7.7 lower than the prior year, largely due to the Missouri Supreme Court ruling in the current quarter that reversed $9.0 of previously disallowed pension expenses relating to the 2018 rate case. Depreciation and amortization increased $1.7 in the current quarter versus the prior-year quarter due to ongoing capital investments.

Other income was up $21.7, primarily due to due the impact of the Nonservice Cost Transfer. Removing this impact, other income increased $2.0, primarily due to increases in the value of investments associated with non-qualified employee benefit plans reflecting market conditions.

Degree days in Spire Missouri’s service areas during the three months ended March 31, 2021, were 1.7% warmer than normal, but 10.5% colder than the same period last year, resulting in higher usage on a year-over-year comparative basis. Spire Missouri’s total system therms sold and transported were 772.9 million for the three months ended March 31, 2021, compared with 695.3 million for the same period in the prior year. Total off-system therms sold and transported were 12.8 million for the three months ended March 31, 2021, compared with 9.8 million for the same period last year.

Resulting net income for the quarter ended March 31, 2021, increased $18.6 versus the prior-year quarter or $10.1 after removing the after-tax impacts of the $2.2 prior-year true-up of charges for ISRS rulings and $9.0 of previously disallowed pension expense.

Note: In the following discussion, all references to earnings (loss) per share and net economic earnings per share refer to earnings (loss) per common share and net economic earnings per diluted common share.

Consolidated

Spire’s net income was $276.3 for the six months ended March 31, 2021, compared with $200.6 for the six months ended March 31, 2020. Basic and diluted earnings per share for the six months ended March 31, 2021, were $5.21 and $5.20 respectively, compared with basic and diluted earnings per share of $3.78 and $3.77, respectively, for the six months ended March 31, 2020.

55

The in crease in net income of $75.7 reflects a $40.1 increase in net income from the Gas Marketing segment, and a $33.5 increase in net income from the Gas Utility segment, combined with a positive net change of $2.1 in Other.

The Gas Marketing segment was positively impacted by favorable market conditions totaling $31.9, particularly in February of the current year, that drove volume, higher local/regional basis differentials and higher realized value from storage withdrawals. Gas Marketing also benefited from $10.9 ($8.2 after-tax) in favorable fair value mark-to-market adjustments. The Gas Utility segment is higher due to a $27.2 increase at Spire Missouri and a $6.0 increase at Spire Alabama.

Net economic earnings were $272.5 ($5.12 per diluted share) for the six months ended March 31, 2021, compared to $215.8 ($4.06 per diluted share) for the same period last year, reflecting earnings improvements in both the Gas Marketing and Gas Utility segments. These variances are discussed in greater detail below.

Gas Utility

Gas Utility net income increased by $33.5 from the prior year. The Gas Utility segment is higher due principally to a $13.1 increase in Spire Missouri ISRS revenues (including the impact of a prior-year provision of $4.2 related to the ISRS ruling settled later in the year), the Missouri Supreme Court ruling that partially reversed 2018 rate case pension cost disallowances totaling $9.0 ($6.8 after-tax), $8.4 higher contribution margin due to the impacts of colder weather, $3.0 in net favorable RSE adjustments at Spire Alabama, and lower run-rate operating costs. These positive impacts offset higher depreciation and amortization reflecting increased capital investment.

Net economic earnings in the current year were $236.1, an increase of $22.7 over the same period in the prior year. The increase was primarily driven by higher contribution margin and lower operations and maintenance expense, after adjusting for the Year-To-Date Postretirement Nonservice Cost Transfer. These impacts are described in further detail below.

Gas Marketing

The Gas Marketing segment reported net income of $40.1 for the six months ended March 31, 2021, versus no net income during the same period last year, principally reflecting strong second quarter operating results in the current year, driven by market conditions due to extreme weather that resulted in higher value realization of storage withdrawals. Gas Marketing also benefited from $8.2 in after-tax favorable year-over-year fair value mark-to-market valuations. Net economic earnings for the current year were $43.1, an increase of $31.9 from the same period last year as favorable market conditions more than offset higher operating costs.

Other

For the six months ended March 31, 2021, net economic loss for Other was $6.7, an improvement from $8.8 in the prior-year period. Included in those results was a $4.4 reduction in the net loss from Spire Storage, offset by slightly higher corporate and interest costs.

Consolidated

Spire’s operating revenues increased by $341.6 at the Gas Utility segment, and Other increased by $6.5. These increases more than offset the $7.4 decline in the Gas Marketing segment. The Gas Utility increase was due principally to $182.9 of higher gas costs (including $195.8 of cover charges and OFO penalties to certain wholesale customers), a $94.4 increase in higher off-system sales, and a $41.2 increase due to weather/volumetric impacts (net of weather mitigation). The Gas Utility segment also benefited from higher ISRS revenues at Spire Missouri and a favorable net RSE adjustment at Spire Alabama. The Gas Marketing decrease was due to higher trading activity (trading activities are recorded as revenues net of costs) offsetting higher volumes and prices volumes, while Other reflects an added $4.1 from STL Pipeline which entered service in late calendar 2019 and $2.4 higher revenues at Spire Storage.

Spire’s contribution margin increased $92.4 compared with the same six-month period last year, with all segments reporting increases. The Gas Utility contribution margin increased $29.6, primarily driven by the $24.9 increase from Spire Missouri and the $5.0 increase at Spire Alabama. The $56.3 increase in Gas Marketing reflects very favorable weather conditions in the current year second quarter, combined with favorable fair value mark-to-market adjustments. Higher contribution margins at the STL Pipeline are consistent with its in-service date earlier this year, and Spire Storage’s improvement reflects higher utilization of its storage capacity.

Depreciation and amortization expenses were higher in the Gas Utility segment, due to higher capital investments in both Spire Missouri and Spire Alabama. Gas Utility O&M expenses were $2.6 higher in the current year driven primarily by the Year-To-Date Postretirement Nonservice Cost Transfer of $18.1. Excluding this adjustment, O&M expenses were lower by $15.5 largely due to the Missouri Supreme Court ruling that partially reversed 2018 rate case pension cost disallowances totaling $9.0. These fluctuations are described in more detail below.

57

Gas Utility

Operating Revenues – Gas Utility operating revenues for the six months ended March 31, 2021, were $1,551.3, or $341.6 higher than the same period last year. The increase in Gas Utility operating revenues was attributable to the following factors:

Spire Missouri and Spire Alabama – Higher PGA/GSA costs |  | $ | 182.9 |
Spire Missouri and Spire Alabama – Off -system sales and capacity release |  |  | 94.4 |
Spire Missouri and Spire Alabama – Volumetric usage (net of weather mitigation) |  |  | 41.2 |
Spire Missouri – ISRS (including ISRS rulings prior year true-up) |  |  | 13.1 |
Spire Alabama – RSE adjustments, net |  |  | 2.5 |
All other factors |  |  | 7.5 |
Total Variation |  | $ | 341.6 |

The increase in revenues was driven primarily by a $182.9 increase in gas costs (including $195.8 of cover charges and OFO penalties to certain wholesale customers), a $94.4 increase in off-system sales, and higher weather/volumetric impacts of $41.2. The segment also benefited from a $13.1 increase of Spire Missouri ISRS (net of ISRS ruling provision), and by a $2.5 increase due to Spire Alabama’s RSE rate renewal.

Contribution Margin – Gas Utility contribution margin was $664.0 for the six months ended March 31, 2021, a $29.6 increase over the same period last year. The increase was attributable to the following factors:

Spire Missouri – ISRS (including ISRS rulings prior year true-up) |  | $ | 13.1 |
Spire Missouri and Spire Alabama – Volumetric usage (net of weather mitigation) |  |  | 8.4 |
Spire Alabama – RSE adjustments, net |  |  | 3.0 |
Spire Missouri and Spire Alabama – Off-system sales and capacity release |  |  | 2.2 |
All other factors |  |  | 2.9 |
Total Variation |  | $ | 29.6 |

The contribution margin increase resulted primarily from Missouri ISRS (net of ISRS ruling provisions), higher volumetric margins, Spire Alabama RSE adjustment impacts and higher off-system sales.

Operating Expenses – Gas Utility O&M expenses increased $2.6 from last year. Removing the Year-To-Date Postretirement Nonservice Cost Transfer, the year-over-year variance is a decrease of $15.5. Of this decrease, $9.0 is attributable to the Missouri Supreme Court ruling that partially reversed 2018 rate case pension cost disallowances. The remaining decrease of $6.5 is due to lower operations and employee-related costs. Depreciation and amortization expenses for the six months ended March 31, 2021, increased $4.7 from the same period last year as a result of continued levels of capital investment in excess of depreciation expense.

Gas Marketing

Operating Revenues – Gas Marketing operating revenues decreased $7.4 from the same period last year, principally due to a net reduction in revenue billed to retail customers.

Contribution Margin – Gas Marketing contribution margin during the six months ended March 31, 2021, increased $56.3 from the same period last year, driven principally by strong second quarter results in the current year. During this quarter, particularly the month of February, very favorable weather patterns drove significantly higher regional basis differentials and volume. The current year also benefited from a favorable net $10.9 year-over-year swing in derivative activity and mark-to-market valuations. More discussion of the effects on Gas Marketing of the February 2021 cold weather event and related disputes is included in the corresponding section of “Earnings – Three Months Ended March 31, 2021” above.

58

Interest Charges

Consolidated interest charges during the six months ended March 31, 2021, were $2.4 lower than the same period last year. The decrease was primarily driven by slightly lower average short-term interest rates in the current period offsetting the impact of net long-term debt issuances and higher levels of short-term borrowings. For the six months ended March 31, 2021 and 2020, average short-term borrowings were $681.4 and $636.4, respectively, and the average interest rates on these borrowings were 0.4% and 2.1%, respectively.

Income Taxes

Consolidated income tax expense during the six months ended March 31, 2021 increased $24.1 versus the prior year. The variance is the result of the higher pre-tax book income in the current year, combined with a higher effective tax rate in the current year due to mix of earnings.

Operating Revenues |  | $ | 1,146.4 |  |  | $ | 831.5 |
Net Income |  | $ | 149.7 |  |  | $ | 122.5 |

Operating revenues during the six months ended March 31, 2021, increased $314.9 from the same period last year primarily due to a $184.1 increase attributable to higher gas costs, a $92.2 increase due to higher off-system sales, and a $21.2 increase in volumetric impacts (net of weather mitigation) relating to colder weather conditions in the current year. Spire Missouri also benefited from $13.1 higher ISRS (including ISRS rulings provision true-up) and a $1.2 increase due to customer growth.

Contribution margin increased $24.9 versus the same period in the prior year. The variance was attributable to the previously mentioned $13.1 increase in ISRS, $7.0 higher volumetric margins, primarily the result of colder weather, and $1.2 related to customer growth.

O&M expenses during the six months ended March 31, 2021, increased $9.4 from the same period last year. Excluding the Year-To-Date Postretirement Nonservice Cost Transfer of $19.4, O&M was $10.0 lower in the current year versus the prior-year period. This decrease is primarily the result of the Missouri Supreme Court ruling that partially reversed 2018 rate case pension cost disallowances totaling $9.0. Depreciation increased by $3.1 as a result of continuing capital investment.

Spire Missouri’s other income increased $23.4 versus the comparable prior-year period. Removing the impact of the Year-To-Date Postretirement Nonservice Cost Transfer of $19.4, other income increased $4.0, primarily due to increases in the value of investments associated with non-qualified employee benefit plans reflecting market conditions.

Temperatures in Spire Missouri’s service areas during the six months ended March 31, 2021, were 0.4% colder than the same period last year but 4.7% warmer than normal. The Spire Missouri total system therms sold and transported were 1,295.7 million for the six months ended March 31, 2021, compared with 1,251.4 million for the same period last year. Total off-system therms sold and transported were 21.3 million for the six months ended March 31, 2021, compared with 18.5 million for the same period last year.

Operating Revenues |  | $ | 336.2 |  |  | $ | 311.7 |
Net Income |  | $ | 77.0 |  |  | $ | 71.0 |

Operating revenues for the six months ended March 31, 2021, increased $24.5 from the same period last year. The change was principally driven by a $20.0 increase in weather and usage impacts (net of weather mitigation) and $2.5 net RSE adjustments (reset and giveback). Off-system sales of $2.2 were only partly offset by lower gas costs of $1.2.

Contribution margin increased $5.0, principally as a result of the RSE adjustments of $3.0 (mentioned above), $1.3 related to higher off-system sales, and $1.4 of weather and usage. O&M expenses for the six months ended March 31, 2021, decreased $5.8 from the same period last year. Excluding the impact of the Year-To-Date Postretirement Nonservice Cost Transfer of $1.1, the decrease of $4.7 was primarily driven by lower operations and employee-related costs.

Temperatures in Spire Alabama’s service area during the six months ended March 31, 2021, were 11.5% colder than the same period last year but 5.9% warmer than normal. Spire Alabama’s total system therms sold and transported were 584.7 million for the six months ended March 31, 2021, compared with 603.7 million for the same period last year. The current year reflects off-system sales, and related therms sold totaled 27.1 million, versus no volume in the prior year as the program had not yet commenced.

REGULATORY MATTERS

For discussions of regulatory matters for Spire, Spire Missouri, and Spire Alabama, see Note 4, Regulatory Matters, of the Notes to Financial Statements in Item 1.

CRITICAL ACCOUNTING ESTIMATES

Our discussion and analysis of our financial condition, results of operations, liquidity, and capital resources are based upon our financial statements, which have been prepared in accordance with GAAP. GAAP requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate our estimates on an ongoing basis. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting estimates used in the preparation of our financial statements are described in Item 7 of the Company’s, Spire Missouri’s, and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2020, and include regulatory accounting, employee benefits and postretirement obligations, impairment of long-lived assets, and income taxes. While accounting estimates related to these and other items such as goodwill and allowance for credit losses were considered in light of the COVID-19 health crisis and the February 2021 cold weather event, there were no significant changes to critical accounting estimates during the six months ended March 31, 2021.

For discussion of other significant accounting policies, see Note 1 of the Notes to Financial Statements included in this Form 10-Q as well as Note 1 of the Notes to Financial Statements included in the Company’s, Spire Missouri’s, and Spire Alabama’s combined Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

The Company’s short-term borrowing requirements typically peak during colder months when the Utilities borrow money to cover the lag between when they purchase natural gas and when their customers pay for that gas. Changes in the wholesale cost of natural gas (including cash payments for margin deposits associated with Spire Missouri’s use of natural gas derivative instruments), variations in the timing of collections of gas cost under the Utilities’ PGA clauses and GSA riders, the seasonality of accounts receivable balances, and the utilization of storage gas inventories cause short-term cash requirements to vary during the year and from year to year, and may cause significant variations in the Company’s cash provided by or used in operating activities.

|  | Six Months Ended March 31, |
Cash Flow Summary |  | 2021 |  |  | 2020 |
Net cash provided by operating activities |  | $ | 159.2 |  |  | $ | 321.7 |
Net cash used in investing activities |  |  | (304.3 | ) |  |  | (344.6 | )
Net cash provided by financing activities |  |  | 245.0 |  |  |  | 125.5 |

For the six months ended March 31, 2021, net cash provided by operating activities decreased $162.5 from the corresponding period of fiscal 2020. The change was due principally to regulatory timing and fluctuations in working capital items, as discussed above.

For the six months ended March 31, 2021, net cash used in investing activities was $40.3 less than for the same period in the prior year, primarily driven by a $42.6 decrease in capital expenditures. The primary driver of the lower capital expenditures was a $42.9 decline related to Spire Storage and Spire STL Pipeline, while Gas Utility expenditures increased slightly. Total capital expenditures for the full fiscal year 2021 are expected to be approximately $590.

Lastly, for the six months ended March 31, 2021, net cash provided by financing activities was $245.0, up $119.5 versus net cash provided of $125.5 for the six months ended March 31, 2020. Current year long-term debt issuances were $325.0, $185.0 less than a year ago, and the issuances of common stock during the first six months of fiscal 2021 were $14.5 less than last year. This was offset by $134.6 less repayments of long-term debt in the current year, as well as $5.5 net short-term debt issued in the current year versus $182.6 net repayments in the prior year.

CAPITAL RESOURCES

The Company’s, Spire Missouri’s and Spire Alabama’s access to capital markets, including the commercial paper market, and their respective financing costs, may depend on the credit rating of the entity that is accessing the capital markets. Our debt is rated by two rating agencies: Standard & Poor’s Corporation (“S&P”) and Moody’s Investors Service (“Moody’s”). As of March 31, 2021, the debt ratings of the Company, Spire Missouri and Spire Alabama, shown in the following table, remain at investment grade with a stable outlook.

| S&P | Moody’s
Spire Inc. senior unsecured long-term debt | BBB+ | Baa2
Spire Inc. preferred stock | BBB | Ba1
Spire Inc. short-term debt | A-2 | P-2
Spire Missouri senior secured long-term debt | A | A1
Spire Alabama senior unsecured long-term debt | A- | A2

It is management’s view that the Company, Spire Missouri and Spire Alabama have adequate access to capital markets and will have sufficient capital resources, both internal and external, to meet anticipated capital requirements, which primarily include capital expenditures, interest payments on long-term debt, scheduled maturities of long-term debt, short-term seasonal needs and dividends.

The effects of COVID-19 on the U.S. capital markets may significantly impact Spire. W e rely on access to the capital markets to fund our capital requirements. These uncertain economic conditions may also result in the inability of our customers to pay for services and could have an impact on our liquidity. Still, considering our financing as described in Note 5, Financing, of the Notes to Financial Statements in Item 1, we believe we have sufficient access to cash to meet our needs.

Cash and Cash Equivalents

Bank deposits were used to support working capital needs of the business. Spire had $100.2 of temporary cash investments as of March 31, 2021.

Short-term Debt

The Utilities’ short-term borrowing requirements typically peak during the colder months, while most of the Company’s other needs are less seasonal. These short-term cash requirements can be met through the sale of commercial paper or through the use of a revolving credit facility. For information about these resources, see Note 5, Financing, of the Notes to Financial Statements in Item 1.

Long-term Debt and Equity

At March 31, 2021, including the current portion but excluding unamortized discounts and debt issuance costs, Spire had long-term debt totaling $2,819.6, of which $1,098.0 was issued by Spire Missouri, $625.0 was issued by Spire Alabama, and $231.6 was issued by other subsidiaries. For more information about long-term debt, see Note 5 of the Notes to Financial Statements in Item 1.

In February 2021, Spire issued 3.5 million equity units for an aggregate stated amount of $175.0, resulting in net proceeds of $169.3 after underwriting fees and other issuance costs. See Note 5 of the Notes to Financial Statements in Item 1 for additional discussion of these equity units.

Spire Missouri was authorized by the MoPSC to issue registered securities (first mortgage bonds, unsecured debt and preferred stock), common stock, and private placement debt in an aggregate amount of up to $660.0 for financings placed any time before September 30, 2023. As of March 31, 2021, the entire $660.0 remained available under this authorization. Spire Alabama has no standing authority to issue long-term debt and must petition the APSC for each planned issuance. On March 24, 2020, the APSC approved an application for up to $150.0 of additional long-term debt financing for Spire Alabama, which was ultimately issued on December 15, 2020.

Spire has a shelf registration statement on Form S-3 on file with the U.S. Securities and Exchange Commission (SEC) for the issuance and sale of up to 250,000 shares of common stock under its Dividend Reinvestment and Direct Stock Purchase Plan. There were 194,709 and 189,751 shares at March 31, 2021 and April 30, 2021, respectively, remaining available for issuance under this Form S-3. Spire and Spire Missouri also have a universal shelf registration statement on Form S-3 on file with the SEC for the issuance of various equity and debt securities, which expires on May 14, 2022.

On February 6, 2019, Spire entered into an “at-the-market” equity distribution agreement, supplemented as of May 14, 2019, pursuant to which the Company may offer and sell, from time to time, shares of its common stock having an aggregate offering price of up to $150.0. Those shares are issued pursuant to Spire’s universal shelf registration statement referenced above and a prospectus supplement dated May 14, 2019. Under this program, a total of 626,249 shares were issued in fiscal 2019 and 2020, and as of March 31, 2021, Spire can still issue shares having an aggregate offering price of up to $102.2.

Including the current portion of long-term debt, the Company’s long-term consolidated capitalization at March 31, 2021, consisted of 49% equity and at September 30, 2020, consisted of 50% equity.

CONTRACTUAL OBLIGATIONS

During the six months ended March 31, 2021, except for the issuance of $150.0 of ten-year notes by Spire Alabama and the $175.0 of notes issued by Spire as part of the equity units described in Note 5, Financing, of the Notes to Financial Statements in Item 1, there were no material changes outside the ordinary course of business to the estimated contractual obligations from the disclosure provided in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2020.

MARKET RISK

There were no material changes in the Company’s commodity price risk or counterparty credit risk as of March 31, 2021, relative to the corresponding information provided in the Company’s Annual Report on Form 10-K as of September 30, 2020. During the first quarter of fiscal 2019, the Company entered into a three-year interest rate swap with a fixed interest rate of 3.250% and a notional amount of $100.0 to protect itself against adverse movements in interest rates on future interest rate payments. The Company recorded a $32.2 mark-to-market gain on this swap for the six months ended March 31, 2021. In the second quarter of 2020, the Company entered into multiple three-year interest rate swaps with fixed interest rates ranging from 0.921% to 1.3105% for a total notional amount of $150.0 to protect itself against adverse movements in interest rates on future interest rate payments. The Company recorded a $27.9 mark-to-market gain on these swaps for the six months ended March 31, 2021. In the second quarter of 2021, the Company entered into a three-year interest rate swap with a fixed interest rate of 2.12% for a total notional amount of $25.0 to protect itself against adverse movements in interest rates on future interest rate payments. The Company recorded a $0.5 mark-to-market gain on these swaps for the six months ended March 31, 2021. As of March 31, 2021, the Company has recorded through other comprehensive income a cumulative mark-to-market net asset of $6.5 on open swaps.

ENVIRONMENTAL MATTERS

The Utilities and other Spire subsidiaries own and operate natural gas distribution, transmission and storage facilities, the operations of which are subject to various environmental laws and regulations, along with their interpretations. While environmental issues resulting from such operations arise in the ordinary course of business, such issues have not materially affected the Company’s, Spire Missouri’s, or Spire Alabama’s financial position and results of operations. As environmental laws, regulations, and interpretations change, however, the Company and the Utilities may be required to incur additional costs. For information relative to environmental matters, see Contingencies in Note 10 of the Notes to Financial Statements in Item 1.

OFF-BALANCE SHEET ARRANGEMENTS

At March 31, 2021, the Company had no off-balance-sheet financing arrangements other than surety bonds and letters of credit entered into in the ordinary course of business. The Company does not expect to engage in any significant off-balance-sheet financing arrangements in the near future.
