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 key legislation affecting operations or key regulatory developments disclosed in Note 13 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2024.

The VCEA includes an energy efficiency target of 5% energy savings, as measured from a 2019 baseline, through verifiable energy efficiency programs by the end of 2025 with future targets to be set by the Virginia Commission. Virginia Power has the opportunity to offset the lost revenues with margins on program spend if certain targets are achieved and can also seek recovery of the lost revenues associated with energy efficiency programs if such reductions are found to have caused Virginia Power to earn more than 50 basis points below a fair rate of return on its rates for generation and distribution services. In February 2025, the Virginia Commission issued its order establishing energy savings targets for Virginia Power of 3.00% for 2026, 4.00% for 2027 and 5.00% for 2028, as measured from a 2019 baseline.

In March 2025, Virginia Power filed its base rate case and accompanying schedules in support of the 2025 Biennial Review in accordance with legislation enacted in Virginia in April 2023. Virginia Power’s earnings test analysis, as filed, demonstrated it earned a combined ROE of 7.77% on its generation and distribution services for the test period, compared to the ROE of 9.70% authorized by the Virginia Commission. Accordingly, no regulatory liability for Virginia Power ratepayer credits to customers has been recorded at March 31, 2025. Virginia Power proposed a base rate increase of $822 million effective January 2026 with an incremental base rate increase of $345 million effective January 2027. Alternatively, Virginia Power has proposed to include purchased electric capacity expenses as a component of fuel expenses instead of base rates. If the shift is approved, Virginia Power’s proposed base rate increase would be $458 million effective January 2026 with an incremental base rate increase of $173 million effective January 2027. The base rate proposals reflect necessary investments in assets and operating resources, including the impact of significant inflationary pressures on labor, materials and equipment since the 2023 Biennial Review, required to reliably serve a growing customer base. The proposed base rates reflect an ROE of 10.40% utilizing a common equity capitalization to total capitalization ratio of 52.10%. The ROE authorized by the Virginia Commission will be applied to Virginia Power’s riders prospectively and will also be utilized to measure base rate earnings for the 2027 Biennial Review. This matter is pending.

In March 2025, Virginia Power filed its annual fuel factor with the Virginia Commission to recover an estimated $2.6 billion in Virginia jurisdictional projected fuel expense for the rate year beginning July 1, 2025 and a projected $205 million under-recovered balance as of June 30, 2025. Virginia Power has proposed to include purchased electric capacity expenses as a component of fuel expenses, consistent with its filing in the 2025 Biennial Review. In addition to the projected energy-related fuel expense, Virginia Power projects $120 million of purchased electric capacity expense to be incurred with PJM from January 1, 2026 to June 30, 2026. Virginia Power’s proposed fuel rate, including purchased electric capacity expense, represents a fuel revenue increase of $860 million when applied to projected kilowatt-hour sales for the rate year beginning July 1, 2025. This matter is pending.

In April 2025, Virginia Power requested approval from the Virginia Commission to issue and sell to Dominion Energy up to $3.5 billion of authorized but unissued shares of its common stock, no par value, through the end of 2025 to maintain adequate credit metrics and efficient access to capital markets while funding necessary capital expenditures. This matter is pending.

In October 2024, Virginia Power filed a petition with the Virginia Commission for CPCNs to construct or acquire and operate two utility-scale projects totaling approximately 208 MW of solar generation as part of its efforts to meet the renewable generation development targets under the VCEA.

The projects, as of October 2024, are expected to cost approximately $605 million in the aggregate, excluding financing costs, and be placed into service between 2026 and 2028. In April 2025, the Virginia Commission approved the petition.

In March 2025, Virginia Power filed a petition with the Virginia Commission for a CPCN to construct and operate the Chesterfield Energy Reliability Center. The project, if approved, is expected to cost approximately $1.5 billion in the aggregate, excluding financing costs, have a generating capacity of 944 MW and be placed into service in 2029. This matter is pending.

Other than the following matters, there have been no significant developments regarding the significant riders associated with various Virginia Power projects disclosed in Note 13 to the Consolidated Financial Statements in the Companies’ Annual Report on Form 10-K for the year ended December 31, 2024.

Represents the cost estimate included in the application except as updated in the approval if applicable. In addition, Virginia Power had various other transmission projects applied for and currently pending approval with aggregate cost estimates of approximately $65 million.

In February 2024, the Virginia Commission issued its order in the 2023 Biennial Review. In connection with the order, Virginia Power recorded a net benefit of $17 million ($12 million after-tax) in the first quarter of 2024 within impairment of assets and other charges in its Consolidated Statements of Income for a regulatory asset for previously unrecovered severe weather event costs, which were amortized by the end of 2024.

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 February 2025, DESC filed with the South Carolina Commission a proposal to increase the total fuel cost component of retail electric rates. DESC’s proposed adjustment is designed to recover DESC’s current base fuel costs, including its existing under-collected balance, over the 12-month period beginning with the first billing cycle of May 2025. In addition, DESC proposed an increase to its variable environmental and avoided capacity cost component. The net effect is a proposed annual increase of $154 million. In March 2025, DESC and the South Carolina Office of Regulatory Staff filed a settlement agreement with the South Carolina Commission for approval to make certain adjustments to the February 2025 filing that would result in an inconsequential change to the proposed annual increase. In April 2025, the South Carolina Commission approved the settlement agreement, with rates effective with the first billing cycle of May 2025.

DESC has approval for a DSM rider through which it recovers expenditures related to its DSM programs. In January 2025, DESC filed an application with the South Carolina Commission seeking approval to recover $46 million of costs and net lost revenues associated with these programs, along with an incentive to invest in such programs. DESC requested that rates be effective with the first billing cycle of May 2025. In April 2025, the South Carolina Commission approved the request, effective with the first billing cycle of May 2025.

In December 2024, DESC filed an application with the South Carolina Commission requesting approval of a CPCN to construct and operate the Ritter - Yemassee Transmission Line #2, comprised of a 17-mile 230 kV transmission line and associated facilities in Colleton and Hampton Counties, South Carolina with an estimated total project cost of $55 million. In April 2025, the South Carolina Commission approved the application.
