Item 8.01. Other Events
In October 2021, American Electric Power Company, Inc. (AEP) and AEP Transmission Company, LLC (AEPTCo) entered into a Stock Purchase Agreement (SPA) to sell Kentucky Power Company (KPCo) and AEP Kentucky Transmission Company, Inc. (KTCo) to Liberty Utilities Co., a subsidiary of Algonquin Power & Utilities Corp. (Liberty). The SPA contained certain termination rights if the closing of the sale did not occur by April 26, 2023. As a result of filings made in March 2023 by intervenors with the FERC, in April 2023, AEP, AEPTCo and Liberty entered into a Mutual Termination Agreement (Termination Agreement) terminating the SPA. The parties entered into the Termination Agreement as all of the conditions precedent to closing the sale could not be satisfied prior to April 26, 2023. Consequently, the assets and liabilities of KPCo and KTCo were reclassified out of Held for Sale on the March 31, 2023 and December 31, 2022 balance sheets of AEP and AEPTCo included within the Quarterly Report on Form 10-Q for the quarter ended March 31, 2023 ("First Quarter 2023 Form 10-Q") as filed with the Securities and Exchange Commission on May 4, 2023.
AEP is filing this Current Report on Form 8-K to recast AEP's and AEPTCo's consolidated financial statements and certain other financial information originally included in AEP’s Annual Report on Form 10-K for the year ended December 31, 2022 (the "2022 Form 10-K") as filed with the SEC on February 23, 2023, to reclassify the assets and liabilities out of Held for Sale on the December 31, 2022 and December 31, 2021 balance sheets of AEP and AEPTCo. The information included in Exhibit 99.1 to this Current Report on Form 8-K solely reflects the presentation of the assets and liabilities no longer being classified as Held for Sale on the balance sheets of AEP and AEPTCo for all periods presented.
AEP has recast the following portions of the 2022 Form 10-K to reflect the presentation of the assets and liabilities no longer classified as Held for Sale on the balance sheets of AEP and AEPTCo:

Item 7. | Management's Discussion and Analysis of Financial Condition and Results of Operations
Item 7A. | Quantitative and Qualitative Disclosures About Market Risk
Item 8. | Financial Statements and Supplementary Data
Item 15. | Exhibits and Financial Statement Schedules

The recast portions of the 2022 Form 10-K described above are attached as Exhibit 99.1 and incorporated herein by reference.
The information included in Exhibit 99.1 to this Current Report on Form 8-K is presented in connection with the presentation changes described above and does not otherwise amend or restate the 2022 Form 10-K. Exhibit 99.1 does not reflect any information or events occurring subsequent to the filing of the 2022 Form 10-K, other than as described in Note 7 – Acquisitions, Assets and Liabilities Held for Sale, Dispositions and Impairments in the Combined Notes to the Consolidated Financial Statements included in Exhibit 99.1, and does not modify or update the disclosures therein in any way, other than to reflect the presentation of the assets and liabilities no longer being classified as Held for Sale on the balance sheets of AEP and AEPTCo as described above.
Therefore, the information contained herein should be read in conjunction with the 2022 Form 10-K and other filings with the SEC under the Securities Exchange Act of 1934 subsequent to the filing of the 2022 Form 10-K, including the First Quarter 2023 Form 10-Q.
The 2022 Form 10-K was a combined annual report of AEP and its registrant subsidiaries, AEP Texas Inc. (AEP Texas), AEP Transmission Company, LLC (AEPTCo), Appalachian Power Company (APCo), Indiana Michigan Power Company (I&M), Ohio Power Company (OPCo), Public Service Company of Oklahoma (PSO) and Southwestern Electric Power Company (SWEPCo). The recast of AEP’s and AEPTCo's consolidated financial statements and certain other financial information filed with this Current Report on Form 8-K to reflect the presentation of the assets and liabilities no longer classified as Held for Sale on the balance sheets of AEP and AEPTCo as described above does not change the financial statements of AEP Texas, APCo, I&M, OPCo, PSO and

SWEPCo as previously filed; accordingly, the financial statements and related disclosures of AEP Texas, APCo, I&M, OPCo, PSO and SWEPCo, although included in the information contained in Exhibit 99.1 of this Current Report on Form 8-K, have not been recast and have not been modified.
