EVERGY KANSAS CENTRAL, INC.

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization

Evergy is a public utility holding company incorporated in 2017 and headquartered in Kansas City, Missouri. Evergy operates primarily through the following wholly-owned direct subsidiaries listed below.

•Evergy Kansas Central, Inc. (Evergy Kansas Central) is an integrated, regulated electric utility that provides electricity to customers in the state of Kansas. Evergy Kansas Central hasone active wholly-owned subsidiary with significant operations, Evergy Kansas South, Inc. (Evergy Kansas South).

•Evergy Transmission Company, LLC (Evergy Transmission Company) owns 13.5% of Transource Energy, LLC (Transource) with the remaining 86.5% owned by AEP Transmission Holding Company, LLC, a subsidiary of American Electric Power Company, Inc. (AEP). Transource is focused on the development of competitive electric transmission projects. Evergy Transmission Company accounts for its investment in Transource under the equity method.

Evergy Kansas Central also owns a 50% interest in Prairie Wind Transmission, LLC (Prairie Wind), which is a joint venture between Evergy Kansas Central and subsidiaries of AEP and Berkshire Hathaway Energy Company. Prairie Wind owns a 108-mile,345 kilovolt (kV) double-circuit transmission line that provides transmission service in the Southwest Power Pool, Inc. (SPP). Evergy Kansas Central accounts for its investment in Prairie Wind under the equity method.

Evergy Kansas Central, Evergy Kansas South, Evergy Metro and Evergy Missouri West conduct business in their respective service territories using the name Evergy. Collectively, the Evergy Companies have approximately 15,800 megawatts (MWs) of owned generating capacity and renewable power purchase agreements and engage in the generation, transmission, distribution and sale of electricity to approximately 1.7 million customers in the states of Kansas and Missouri.

Principles of Consolidation

Each of Evergy's, Evergy Kansas Central's and Evergy Metro's consolidated financial statements includes the accounts of their subsidiaries and variable interest entities (VIEs) of which they are the primary beneficiary. Undivided interests in jointly-owned generation facilities are included on a proportionate basis. Intercompany transactions have been eliminated. The Evergy Companies assess financial performance and allocate resources on a consolidated basis (i.e., operate in one segment).

Evergy Metro elected not to apply "push-down accounting" related to the merger that created Evergy in 2018, whereby the adjustments of assets and liabilities to fair value and the resulting goodwill would be recorded on the financial statements of the acquired subsidiary. These adjustments for Evergy Metro, as well as those related to the other acquired assets and liabilities from the merger are only reflected on Evergy's consolidated financial statements.

Use of Estimates

The process of preparing financial statements in conformity with generally accepted accounting principles (GAAP) requires the use of estimates and assumptions that affect the reported amounts of certain types of assets, liabilities, revenues and expenses. Such estimates primarily relate to unsettled transactions and events as of the date of the financial statements. Accordingly, upon settlement, actual results may differ from estimated amounts.

Cash, Cash Equivalents and Restricted Cash

Cash equivalents consist of highly liquid investments with original maturities of three months or less at acquisition. Evergy has restricted cash included in Other Current Assets and Other Non-current Assets on Evergy's consolidated balance sheets to facilitate the servicing of Evergy Missouri West Storm Funding I, LLC's (Evergy Missouri West Storm Funding) debt and the funding requirements for a jointly-owned generation facility. See Note 19 for additional information on the VIE. The following table summarizes the cash, cash equivalents and restricted cash included on Evergy's consolidated balance sheets.

Fuel Inventory and Supplies

The Evergy Companies record fuel inventory and supplies at average cost. The following table separately states the balances for fuel inventory and supplies.

Property, Plant and Equipment

The Evergy Companies record the value of property, plant and equipment, including that of VIEs, at cost. For plant, cost includes contracted services, direct labor and materials, indirect charges for engineering and supervision and an allowance for funds used during construction (AFUDC). AFUDC represents the allowed cost of capital used to finance utility construction activity. AFUDC equity funds are included as a non-cash item in other income and AFUDC borrowed funds are a reduction of interest expense. AFUDC is computed by applying a composite rate to qualified construction work in progress (CWIP). The rates used to compute gross AFUDC are compounded semi-annually.

The amounts of the Evergy Companies' AFUDC for borrowed and equity funds are detailed in the following table.

The average rates used in the calculation of AFUDC are detailed in the following table.

When property units are retired or otherwise disposed, the original cost, net of salvage, is charged to accumulated depreciation. Repair of property and replacement of items not considered to be units of property are expensed as incurred, except for planned refueling and maintenance outages at Wolf Creek Generating Station (Wolf Creek). As authorized by regulators, the incremental maintenance cost incurred for such outages is deferred and amortized to expense ratably over the period between planned outages.

Depreciation and Amortization

Depreciation and amortization of utility plant other than nuclear fuel is computed using the straight-line method over the estimated lives of depreciable property based on rates approved by state regulatory authorities. Annual depreciation rates average approximately 3%. See Note 7 for more details. Nuclear fuel is amortized to fuel expense based on the quantity of heat produced during the generation of electricity.

The depreciable lives of Evergy's, Evergy Kansas Central's and Evergy Metro's property, plant and equipment are detailed in the following table.

Abandoned Plant

When the Evergy Companies retire utility plant, the original cost, net of salvage, is charged to accumulated depreciation. However, when it becomes probable an asset will be retired significantly in advance of its original expected useful life and in the near term, the cost of the asset and related accumulated depreciation is recognized as a separate asset and a probable abandonment. If the asset is still in service, the net amount is classified as plant to be retired, net on the consolidated balance sheets. If the asset is no longer in service, the net amount is classified as a regulatory asset on the consolidated balance sheets.

The Evergy Companies must also assess the probability of full recovery of the remaining net book value of the abandonment. The net book value that may be retained as an asset on the balance sheet for the abandonment is dependent upon amounts that may be recovered through regulated rates, including any return. An impairment charge, if any, would equal the difference between the remaining net book value of the asset and the present value of the future revenues expected from the asset.

Nuclear Plant Decommissioning Costs

Nuclear plant decommissioning cost estimates are based on either the immediate dismantling method or the deferred dismantling method as determined by the State Corporation Commission of the State of Kansas (KCC) and Public Service Commission of the State of Missouri (MPSC) and include the costs of decontamination, dismantlement and site restoration. Based on these cost estimates, Evergy Kansas Central and Evergy Metro each contribute to a tax-qualified trust fund to be used to decommission Wolf Creek. Related liabilities for decommissioning are included on Evergy's, Evergy Kansas Central's and Evergy Metro's consolidated balance sheets in asset retirement obligations (AROs).

As a result of the authorized regulatory treatment and related regulatory accounting, differences between the fair value of the assets held in the nuclear decommissioning trust and the amounts recorded for the accumulated accretion and depreciation expense associated with the decommissioning ARO are recorded as a regulatory liability on Evergy's, Evergy Kansas Central's and Evergy Metro's consolidated balance sheets. See Note 6 for discussion of AROs including those associated with nuclear plant decommissioning costs.

Regulatory Accounting

Accounting standards are applied that recognize the economic effects of rate regulation. Accordingly, regulatory assets and liabilities have been recorded when required by a regulatory order or based on regulatory precedent. See Note 4 for additional information concerning regulatory matters.

Cash Surrender Value of Life Insurance

Amounts related to corporate-owned life insurance (COLI) are recorded on the consolidated balance sheets in other long-term assets and are detailed in the following table for Evergy. Substantially all of Evergy's COLI-related balances relate to Evergy Kansas Central's COLI activity.

Increases in cash surrender value and death benefits are recorded in other income in the Evergy Companies' consolidated statements of income and comprehensive income. Interest expense incurred on policy loans is offset against the policy income. Income from death benefits is highly variable from period to period.

Fair Value of Financial Instruments

The following methods and assumptions were used to estimate the fair value of the following financial instruments for which it was practicable to estimate that value.

Nuclear decommissioning trust - The Evergy Companies' nuclear decommissioning trust assets are recorded at fair value based on quoted market prices of the investments held by the fund and/or valuation models.

Derivative instruments - The Evergy Companies' derivative instruments are recorded at fair value based on quoted market prices for exchange-traded derivative instruments, quoted prices for similar contracts and/or valuation models.

Pension plans - For financial reporting purposes, the market value of plan assets is the fair value based on quoted market prices of the investments held by the fund and/or valuation models.

Derivative Instruments

The Evergy Companies record derivative instruments on the balance sheet at fair value in accordance with GAAP. The Evergy Companies enter into derivative contracts to manage risk exposure to commodity price and interest rate fluctuations and also for trading purposes. See Note 13 for additional information regarding derivative financial instruments and hedging activities.

Revenue Recognition

The Evergy Companies recognize revenue on the sale of electricity to customers over time as the service is provided in the amount they have the right to invoice. Revenues recorded include electric services provided but not yet billed by the Evergy Companies. Unbilled revenues are recorded for kilowatt hour (kWh) usage in the period following the customers' billing cycle to the end of the month. This estimate is based on net system kWh usage less actual billed kWhs. The Evergy Companies' estimated unbilled kWhs are allocated and priced by regulatory jurisdiction across the rate classes based on actual billing rates. The Evergy Companies' unbilled revenue estimate is affected by factors including fluctuations in energy demand, weather, line losses and changes in the composition of customer classes. See Note 3 for the balance of unbilled receivables for each of Evergy, Evergy Kansas Central and Evergy Metro as of December 31, 2025 and 2024.

The Evergy Companies also collect sales taxes and franchise fees from customers concurrent with revenue-producing activities that are levied by state and local governments. These items are excluded from revenue, and thus are not reflected on the consolidated statements of income and comprehensive income for Evergy, Evergy Kansas Central and Evergy Metro.

See Note 2 for additional details regarding revenue recognition from sales of electricity by the Evergy Companies.

Allowance for Credit Losses

Historical loss information generally provides the basis for the Evergy Companies' assessment of expected credit losses. The Evergy Companies use an aging of accounts receivable method to assess historical loss information. When historical experience may not fully reflect the Evergy Companies' expectations about the future, the Evergy Companies will adjust historical loss information, as necessary, to reflect the current conditions and reasonable and supportable forecasts not already reflected in the historical loss information.

Receivables are charged off when they are deemed uncollectible, which is based on a number of factors including specific facts surrounding an account and management's judgment.

Asset Impairments

Long-lived assets and finite-lived intangible assets subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If the sum of the undiscounted expected future cash flows from an asset to be held and used is less than the carrying value of the asset, an asset impairment must be recognized in the financial statements. The amount of impairment recognized is the excess of the carrying value of the asset over its fair value.

Goodwill and indefinite lived intangible assets are tested for impairment annually and when an event occurs indicating the possibility that an impairment exists. The annual test must be performed at the same time each year. The goodwill impairment test consists of comparing the fair value of a reporting unit to its carrying amount, including goodwill, to identify potential impairment. In the event that the carrying amount exceeds the fair value of the reporting unit, an impairment loss is recognized for the difference between the carrying amount of the reporting unit and its fair value. See Note 5 for additional details on goodwill.

Income Taxes

Income taxes are accounted for using the asset/liability approach. Deferred tax assets and liabilities are determined based on the temporary differences between the financial reporting and tax bases of assets and liabilities, applying enacted statutory tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion of the deferred tax assets will not be realized.

The Evergy Companies recognize tax benefits based on a "more-likely-than-not" recognition threshold. In addition, the Evergy Companies recognize interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expenses.

Evergy files a consolidated federal income tax return as well as unitary and combined income tax returns in several state jurisdictions with Kansas and Missouri being the most significant. Income taxes for consolidated or combined subsidiaries are allocated to the subsidiaries based on separate company computations of income or loss. Evergy Kansas Central's and Evergy Metro's income tax provisions include taxes allocated based on their separate company's income or loss.

The Evergy Companies have established a net regulatory liability for future refunds to be made to customers for amounts collected from customers in excess of income taxes in current rates. Tax credits are recognized in the year generated except for certain Evergy Kansas Central, Evergy Metro and Evergy Missouri West investment tax credits that have been deferred and amortized over the remaining service lives of the related properties.

Other Income and Other Expense

The tables below show the detail of other income and other expense, respectively, for each of the Evergy Companies.

Investments in Early-Stage Clean Energy and Energy Solution Companies

From time to time, Evergy has made limited non-regulated equity and debt investments in early-stage clean energy and energy solution companies. These investments are recorded in Other Assets - Long-Term on Evergy’s consolidated balance sheets and as of December 31, 2025, and December 31, 2024, the total value of these investments was $41.3 million and $121.4 million, respectively. These investments have historically not had a significant impact on Evergy’s results of operations.

In 2025, Evergy recorded $48.7 million of losses in investment earnings (loss) on its consolidated statements of income and comprehensive income, resulting from a decline in fair value and losses on the sale of certain investments. The losses consisted of $13.5 million of realized losses and $35.2 million of unrealized and impairment losses.

Evergy has initiated a process to dispose of these investments and could experience additional losses or gains on these investments as a result of further changes in their value or upon their ultimate liquidation.

Earnings Per Share

To compute basic earnings per common share (EPS), Evergy divides net income attributable to Evergy, Inc. by the weighted average number of common shares outstanding. Diluted EPS includes the effect of issuable common shares resulting from restricted share units (RSUs), convertible notes, a warrant and forward sale agreements entered into through Evergy's at-the-market (ATM) equity offering program. Evergy computes the dilutive effects of potential issuances of common shares using the treasury stock method, the contingently issuable share method or the if-converted method, as applicable.

The following table reconciles Evergy's basic and diluted EPS.

The effect of dilutive securities for 2025 included 2.6 million shares resulting from Evergy's convertible notes. There wasno dilution resulting from Evergy's convertible notes in 2024 or 2023.

The table below summarizes the anti-dilutive securities excluded from the computation of diluted EPS.

Supplemental Cash Flow Information

Dividends Declared

In February 2026, Evergy's Board of Directors (Evergy Board) declared a quarterly dividend of $0.6950 per share on Evergy's common stock. The common stock dividend is payable March 20, 2026, to shareholders of record as of March 10, 2026.

In February 2026, Evergy Kansas Central's Board of Directors and Evergy Metro's Board of Directors each declared a cash dividend to Evergy of up to $50.0 million payable on or before March 19, 2026.

Missouri Legislation

In April 2025, Missouri Senate Bill (SB) 4 was signed into law by the Governor of Missouri. Most notably, SB 4 establishes new mechanisms for Missouri electric utilities to recover the costs associated with the construction of new natural gas-fired generating units. The utilities will be able to include certain costs of CWIP in rate base. The inclusion of CWIP will be in lieu of AFUDC applicable to the construction of the new natural gas-fired generating units. The MPSC will determine the amount of CWIP that may be included in rate base. Additionally, amounts collected arising from the inclusion of CWIP in rate base are subject to refund under certain circumstances. These provisions are scheduled to expire at the end of 2035. Additionally, the law extends Missouri's existing plant-in service accounting (PISA) provisions to include certain natural gas-fired generating units as qualifying electric plants and extends the sunset date of these provisions through the end of 2035. These provisions allow electric utilities to defer to a regulatory asset for recovery in a subsequent general rate case 85% of depreciation expense and the associated return on investment for qualifying electric plant rate base additions for assets placed in-service between general rate cases.

Natural Gas Plant Investments

The Evergy Companies use integrated resource plans (IRPs), detailed analyses that estimate factors that influence the future supply and demand for electricity, to inform the manner in which they supply electricity. The most recent IRPs incorporate the latest SPP resource adequacy requirements and anticipated load growth. Based on these and other factors, the IRP indicated the addition of new supply side resources, including combined and simple cycle natural gas plants, would be needed.

In October 2024, Evergy announced its plan to construct two combined-cycle natural gas plants located in Kansas. Evergy Kansas Central and Evergy Missouri West will jointly-own each plant and expect each plant to have an initial generating capacity of approximately 705 MWs. The first plant, a combined cycle gas turbine (CCGT) facility located in Sumner County, is expected to begin operations by spring of 2029 and the second plant, a CCGT facility located in Reno County, is expected to begin operations by spring of 2030.

Additionally, Evergy Missouri West plans to construct a 440 MW simple-cycle natural gas plant located in Missouri. The plant is expected to begin operations in 2030.

In 2024, Evergy Kansas Central and Evergy Missouri West requested predetermination from the KCC and a Certificate of Convenience and Necessity (CCN) from the MPSC, respectively, for their planned natural gas investments. In July 2025, the KCC approved a non-unanimous partial settlement agreement regarding Evergy Kansas Central's investments in its planned natural gas plants. In July 2025, the MPSC approved a non-unanimous stipulation and agreement regarding Evergy Missouri West's investments in its planned natural gas plants. See "Applications for Predetermination" and "Requests for Certificate of Convenience and Necessity" in Note 4 for additional information regarding Evergy Kansas Central's and Evergy Missouri West's applications for predetermination and a CCN for their investments in these natural gas plants.

Renewable Plant Investments

Evergy Kansas Central intends to construct and own an approximately 159 MW solar generation facility, to be located in Douglas County Kansas, called Kansas Sky. In July 2024, a lawsuit was filed in the District Court of Douglas County, Grant Township, et al. v. Board of County Commissioners, requesting the court to overturn Douglas County's approval of the application to construct the solar generation facility. Due to the ongoing litigation, including the court's granting of an emergency injunction in December 2024 which temporarily prohibits the construction of the solar generation facility, Evergy Kansas Central is not able to estimate when the solar generation facility will begin operations. In July 2025, the KCC approved a unanimous partial settlement agreement for the Kansas Sky solar investment. See "Applications for Predetermination" in Note 4 for additional information regarding Evergy Kansas Central's application for predetermination for its investment in this renewable generating plant.

In 2024, Evergy Missouri West entered into agreements to own two solar generation facilities currently under development. The first facility, to be called Sunflower Sky, is a solar generation facility to be located in Kansas with an expected generating capacity of approximately 65 MWs. In September 2025, Evergy Missouri West acquired the Sunflower Sky solar facility assets from the developer and will complete construction of the facility. The second facility, to be called Foxtrot, is a solar generation facility to be located in Missouri with an expected generating capacity of approximately 100 MWs. In November 2025, Evergy Missouri West acquired the Foxtrot solar facility assets from the developer and will complete construction of the facility. The solar generation facilities are expected to begin operations by summer of 2027. In July 2025, the MPSC approved a unanimous stipulation and agreement regarding Evergy Missouri West's planned investments in the solar generation facilities. See "Requests for Certificate of Convenience and Necessity" in Note 4 for additional information regarding Evergy Missouri West's application for a CCN for its investment in these renewable generating plants.

New Accounting Pronouncements

Improvements to Income Tax Disclosures

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-09, Improvements to Income Tax Disclosures. This ASU is intended to improve the transparency and decision usefulness of income tax disclosures primarily by enhancing consistency in the categorization and disaggregation of information included in the effective tax rate reconciliation and income taxes paid by jurisdiction. This guidance is effective for annual periods beginning after December 15, 2025. The Evergy Companies adopted ASU No. 2023-09 retrospectively and it is reflected for all periods presented. The adoption of ASU No. 2023-09 did not have a material impact on the Evergy Companies' results of operations, financial positions, or cash flows. See Note 20 for further detail on the updated presentation.

Income Statement—Reporting Comprehensive Income: Expense Disaggregation Disclosures

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income: Expense Disaggregation Disclosures. This ASU is intended to enhance income statement expense disclosures by requiring disaggregated information about specific expenses categories in commonly presented income statement expense captions. ASU No. 2024-03 is effective for annual periods beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. Early adoption is permitted. The Evergy Companies are currently evaluating the disclosure impact of this ASU on their respective consolidated financial statements.
