As a result of issues generated in the ordinary course of business, the Companies are involved in various regulatory matters. Certain regulatory matters may ultimately result in a loss; however, as such matters are in an initial procedural phase, involve uncertainty as to the outcome of pending reviews or orders, and/or involve significant factual issues that need to be resolved, it is not possible for the Companies to estimate a range of possible loss. For regulatory matters that the Companies cannot estimate, a statement to this effect is made in the description of the matter. Other matters may have progressed sufficiently through the regulatory process such that the Companies are able to estimate a range of possible loss. For regulatory matters that the Companies are able to reasonably estimate a range of possible losses, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. Any estimated range is based on currently available information, involves elements of judgment and significant uncertainties and may not represent the Companies’ maximum possible loss exposure. The circumstances of such regulatory matters will change from time to time and actual results may vary significantly from the current estimate. For current matters not specifically reported below, management does not anticipate that the outcome from such matters would have a material effect on the Companies’ financial position, liquidity or results of operations.

Other than the following matters, there have been no significant developments regarding the pending regulatory matters disclosed in Note 13 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2021.

In May 2022, Virginia Power filed its annual fuel factor filing with the Virginia Commission to recover an estimated $2.3 billion in Virginia jurisdictional projected fuel expense for the rate year beginning July 1, 2022 and a projected $1.0 billion under-recovered balance as of June 30, 2022. Virginia Power’s proposed fuel rate represents a fuel revenue increase of $1.8 billion when applied to projected kilowatt-hour sales for that period. Virginia Power also proposed alternatives to recover this under-collected balance over a two- or three-year period. Under these alternatives, Virginia Power’s fuel revenues for the rate year would increase by $1.3 billion or $1.2 billion, respectively. In addition, Virginia Power proposed a change in the timing of fuel cost recovery for certain customers who elect market-based rates that would consider those customers’ portion of the projected under-recovered balance to have been recovered as of June 30, 2022. In July 2022, Virginia Power, the Virginia Commission staff and another party filed a comprehensive settlement agreement with the Virginia Commission for approval. The comprehensive settlement agreement provides for the collection of the requested under-recovered projected fuel expense over a three-year period beginning July 1, 2022 and that Virginia Power will exclude from recovery through base rates one half of the related financing costs over the three-year period. In addition, the proposed settlement agreement affirmed Virginia Power’s proposal regarding fuel cost recovery for market-based rate customers. As a result, Virginia Power recorded a $191 million ($142 million after-tax) charge in the second quarter of 2022 within impairment of assets and other charges in its Consolidated Statement of Income. This matter is pending.

In September 2021, Virginia Power filed a petition with the Virginia Commission for CPCNs to construct and operate 13 utility-scale projects totaling approximately 661 MW of solar generation and 70 MW of energy storage as part of its efforts to meet the renewable generation development requirements under the VCEA. The projects, as of September 2021, are expected to cost approximately $1.4 billion in the aggregate, excluding financing costs, and be placed into service between 2022 and 2023. In March 2022, the Virginia Commission approved the petition.

In November 2021, Virginia Power filed an application with the Virginia Commission requesting approval and certification of the Virginia Facilities component of the CVOW Commercial Project. The onshore Virginia Facilities have an estimated cost of

approximately $1.1 billion, excluding financing costs, which is included within the overall cost of the CVOW Commercial Project. In addition, Virginia Power requested approval from the Virginia Commission to enter into financial hedges with U.S. financial institutions to mitigate the foreign currency exchange risk associated with certain supplier contracts associated with the CVOW Commercial Project. In August 2022, the Virginia Commission approved the application for certification of the Virginia Facilities component of the CVOW Commercial Project and noted that no further action was required with respect to Virginia Power’s foreign currency risk mitigation plan.

In October 2021, Virginia Power filed a petition with the Virginia Commission requesting a determination that it is reasonable and prudent for Virginia Power to pursue a nuclear life extension program to extend the operating licenses of Surry and North Anna and to carry out projects to upgrade or replace systems and equipment necessary to continue to safely and reliably operate these nuclear power stations. The nuclear life extension program is expected to cost approximately $3.9 billion, excluding financing costs. In July 2022, the Virginia Commission approved the petition.

In May 2022, Virginia Power filed a petition with the Virginia Commission requesting a suspension of Rider RGGI approved in August 2021. Virginia Power also requested that RGGI compliance costs incurred and unrecovered through July 2022 be recovered through existing base rates in effect during the period incurred. The Virginia Commission approved the request in June 2022. In the second quarter of 2022, Virginia Power recorded a charge of $180 million ($134 million after-tax) in impairment of assets and other

charges for the amount deemed recovered through base rates through June 30, 2022, including the impact of certain non-jurisdictional customers which follow Virginia Power’s jurisdictional rate methodology.

In March 2019, Virginia Power filed its base rate case and schedules with the North Carolina Commission. In February 2020, the North Carolina Commission issued its final order relating to base rates. In July 2020, Virginia Power filed a notice of appeal and exceptions to the Supreme Court of North Carolina, arguing that the North Carolina Commission committed reversible error on certain issues relating to the ratemaking treatment of certain coal ash remediation costs. In June 2022, the Supreme Court of North Carolina affirmed the North Carolina Commission’s order.

Rider D allows PSNC to recover from customers all prudently incurred gas costs and certain related uncollectible expenses as well as losses on negotiated gas and transportation sales. In May 2022, PSNC submitted a filing with the North Carolina Commission for a $56 million gas cost increase. The North Carolina Commission approved the filing in May 2022 with rates effective June 2022.

DESC has approval for a DSM rider through which it recovers expenditures related to its DSM programs. In January 2022, DESC filed an application with the South Carolina Commission seeking approval to recover $60 million of costs and net lost revenues associated with these programs, along with an incentive to invest in such programs. In April 2022, the South Carolina Commission approved the request, effective with the first billing cycle of May 2022.

DESC’s retail electric rates include a cost of fuel component approved by the South Carolina Commission which may be adjusted periodically to reflect changes in the price of fuel purchased by DESC. In April 2022, the South Carolina Commission approved DESC’s request to increase the total fuel cost component of retail electric rates, effective with the first billing cycle of May 2022. The South Carolina Commission also approved DESC’s request to apply approximately $66 million representing the net balance of funds associated with the monetization of the bankruptcy settlement with Toshiba Corporation following the satisfaction of liens against NND Project property previously recorded in regulatory liabilities, as a reduction to its under-collected base fuel cost balance, along with a requested increase to DESC’s variable environmental and avoided capacity cost component. The net effect is an annual increase of $143 million.

In June 2022, DESC filed with the South Carolina Commission its monitoring report for the 12-month period ended March 31, 2022 with a total revenue requirement of $553 million. This represents a $129 million overall annual increase to its natural gas rates including a $16 million increase under the terms of the Natural Gas Rate Stabilization Act effective with the first billing cycle of November 2022. This matter is pending.

In 2008, East Ohio began PIR, aimed at replacing approximately 25% of its pipeline system. In April 2022, the Ohio Commission approved an extension of East Ohio’s PIR program for capital investments through 2026 with continuation of 3% increases of annual capital expenditures per year.

In June 2022, the Ohio Commission approved East Ohio’s application to adjust the PIR cost recovery rates for 2021 costs. The filing reflects gross plant investment for 2021 of $225 million, cumulative gross plant investment of $2.2 billion and a revenue requirement of $273 million.

In 2011, East Ohio began CEP which enables East Ohio to defer depreciation expense, property tax expense and carrying costs associated with CEP investments. In April 2022, certain parties filed an appeal with the Supreme Court of Ohio appealing the Ohio Commission’s December 2020 order establishing the CEP rider, including the rate of return utilized in determining the revenue requirement. This matter is pending.

In February 2022, the Ohio Commission approved adjustments to CEP cost recovery rates for 2019 and 2020 costs. The approved rates reflect gross plant investment for 2019 and 2020 of $231 million, cumulative gross plant investment of $952 million and a revenue requirement of $118 million. The Ohio Commission also ordered that East Ohio should file its next base rate case by October 2023.

In April 2022, East Ohio filed an application with the Ohio Commission requesting approval to adjust CEP cost recovery rates for 2021 costs. The filing reflects gross plant investment for 2021 of $140 million, cumulative gross plant investment of $1.1 billion and a revenue requirement of $137 million. This matter is pending.

Under the Ohio PIPP Plus Program, eligible customers can make reduced payments based on their ability to pay their bill. The difference between the customer’s total bill and the PIPP amount is deferred and collected under the PIPP rider in accordance with the rules of the Ohio Commission. In July 2022, East Ohio’s annual update of the PIPP rider filed in May 2022 with the Ohio Commission was approved. The revised rider rate reflects recovery over the twelve-month period from July 2022 through June 2023 of projected deferred program costs of approximately $22 million from April 2022 through June 2023, net of over-recovery of accumulated arrearages of approximately $4 million as of March 31, 2022.

East Ohio has approval for a UEX rider through which it recovers the bad debt expense of most customers not participating in the PIPP Plus Program. The UEX rider is adjusted annually to achieve dollar for dollar recovery of East Ohio’s actual writeoffs of uncollectible amounts. In July 2022, the Ohio Commission approved East Ohio’s application to adjust its UEX rider to reflect an annual revenue requirement of $20 million to provide for recovery of an under-recovered accumulated bad debt expense of $7 million as of March 31, 2022, and recovery of net bad debt expense projected to total $13 million for the twelve-month period ending March 2023.

In September 2020, Hope filed its base rate case and schedules with the West Virginia Commission. Hope proposed a non-fuel, base rate increase of $28 million. The base rate increase was proposed to recover the significant investment in distribution infrastructure and costs associated with the acquisition of over 2,000 miles of gathering assets, both for the benefit of West Virginia customers. The proposed rates would provide for an ROE of 10.25% compared to the authorized ROE of 9.45%. In July 2021, the West Virginia Commission approved a non-fuel, base rate increase of $13 million for rates effective July 2021 with an ROE of 9.54%. In August 2021, Hope filed a petition for reconsideration with the West Virginia Commission regarding certain return calculations included in the July 2021 approval order. In June 2022, the West Virginia Commission issued an order resolving this petition without material modification to Hope’s base rates.

In May 2022, Hope filed a PREP application with the West Virginia Commission requesting approval to recover PREP costs related to $59 million and $63 million of projected capital investment for 2022 and 2023 respectively. The application also includes a true-up of PREP costs related to the 2021 actual capital investment of $54 million and sets forth $13 million of annual PREP costs to be recovered in proposed rates effective November 1, 2022. This matter is pending.

In August 2022, Hope filed an application with the West Virginia Commission requesting approval for a $73 million gas cost increase with rates effective November 2022. This matter is pending.

In May 2022, Questar Gas filed its base rate case and schedules with the Utah Commission. Questar Gas proposed a non-fuel, base rate increase of $71 million effective January 2023. The base rate increase was proposed to recover the significant investment in distribution infrastructure for the benefit of Utah customers. The proposed rates would provide for an ROE of 10.3% compared to the currently authorized ROE of 9.5%. This matter is pending.

In July 2022, the Utah Commission approved Questar Gas’ request for a $94 million gas cost increase with rates effective August 2022.
