Dominion Energy, Inc.

The full register, from 13F filings

The Register tab above is hand research: a dozen holders, each traced to the filing it came from. This asks the same question of the whole market for the quarter ended 31-mar-2026, where 1,454 managers reported a position. Broad where the research is deep, and shallow in the ways a 13F always is.

Built from 13F filings, which report US listed, long, US custodied positions only. A register from this source is a floor rather than a level: a holder's true position can be far larger, as BlackRock's ASML stake shows at 1.28m shares in a 13F against 26.3m in its 13G/A. Holdings held through derivatives, outside US custody, or below a manager's reporting obligation do not appear. Where a holder is marked as a family, its total sums several separate filing entities and describes something no single filing describes; the constituent entities and their share counts are listed so the total can be checked. That roll-up can legitimately exceed the family's own Schedule 13G, because a 13G is filed by one legal entity: Vanguard reports Alphabet through ten advisory entities, and The Vanguard Group Inc itself reported zero after its January 2026 disaggregation.

What a reader needs to know to read these numbers

• Dominion Energy has agreed to be acquired by NextEra Energy under a merger agreement disclosed in the Q2 2026 10-Q: each Dominion Energy common share would convert into a pro rata share of $360 million cash plus 0.8138 shares of NextEra Energy common stock at closing. The agreement includes termination fees ($2.24 billion payable by Dominion Energy, $6.52 billion payable by NextEra Energy in specified circumstances) and a termination deadline of November 2027 (subject to extension). This is a pending, unclosed transaction affecting Dominion Energy's own capital structure and share price; it is not a holding or a register entry under this brief's scope, but is material context for interpreting the market cap and share price recorded here.
• Vanguard Group Inc (CIK 0000102909) filed Form 13F-NT (notice, no holdings) for the quarter ended 30 June 2026, consistent with the January 2026 reorganisation of Vanguard's 13F filing structure. Per the brief's Vanguard rule, the register substitutes a single 'The Vanguard Group' row summing the two successor entities that filed 13F-HR for the quarter (Vanguard Capital Management LLC and Vanguard Portfolio Management LLC) rather than listing Vanguard multiple times or treating the parent's absence as zero holdings.
• Capital Group is not the Vanguard successor case: no Capital Group parent filed a 13F-NT. All three named Capital Group 13F filers (Capital World Investors, Capital International Investors, Capital Research Global Investors) were checked individually against their own Q2 2026 13F-HR filings. Only Capital Research Global Investors (CIK 0001422848) held Dominion Energy common stock (73,855,890 shares); the other two entities had no matching CUSIP row in their Q2 2026 information tables.
• Excluded from holdings as a controlled, consolidated subsidiary: OSW Project LLC (OSWP), the entity that owns the Coastal Virginia Offshore Wind (CVOW) Commercial Project. In October 2024, Virginia Power (a Dominion Energy subsidiary) sold a 50% NONcontrolling interest in OSWP to Stonepeak Partners, LLC. Virginia Power retains the controlling interest and consolidates OSWP; Stonepeak's stake is equity an outside investor holds in a Dominion project, which is the reverse direction from what this brief records, not a Dominion holding in someone else.
• Excluded from holdings: Cove Point. Dominion Energy completed the sale of its 50% noncontrolling limited partnership interest in Cove Point to Berkshire Hathaway Energy (BHE) in September 2023 for approximately $3.3 billion in cash. The Q2 2026 10-Q confirms Cove Point is 'previously an equity method investment' and Dominion Energy retains only legacy guarantees (up to $1.9 billion cumulative exposure) supporting terminal services and transportation contracts, not an equity stake. No retained ownership interest is recorded.
• Un-split combined balance not assigned to a named holding: the FY2025 10-K equity-method investments table includes an 'Other (various)' line of $20 million (2025) and $20 million (2024) covering unnamed smaller investments; per the brief's rule against sizing an unnamed investee from a combined balance, no holding is recorded from this line.
• Cross-check: the FY2025 10-K equity-method investments table (Note 9, values in millions) sums to the reported $132 million total: Align RNG $92 (50%) + Dominion Privatization $20 (50%) + Other (various) $20 = $132 million. Atlantic Coast Pipeline is reported separately as a $4 million liability (footnoted), not part of the $132 million asset total. The Q2 2026 10-Q balance sheet shows a combined 'Investment in equity method affiliates' of $127 million at June 30, 2026 (versus $132 million at December 31, 2025) with no individual-investee restatement, consistent with the 10-Q's statement that there have been no significant changes to the equity method investments.
• Register reconciliation: the 2026 proxy's 'Significant Shareholders' table cites older Schedule 13G filings for the five largest holders (Vanguard 105,794,894 shares / 12.04% per a 13G for 30 Jun 2025; BlackRock 69,476,083 / 7.91% per a 13G for 31 Dec 2024; Capital Research Global Investors 54,850,042 / 6.24%; State Street 47,918,597 / 5.45%; Wellington 44,943,745 / 5.11%). These are all older than, and for the same holders as, the Q2 2026 13F-HR data used in the register above, so no separate 13G rows are added; the 13F-HR figures are used as the more current source per the brief's basis hierarchy.
• Market capitalisation of $60.49 billion and the $68.77 share price are stockanalysis.com's figures as of the market close on 17 August 2026. Cross-check: 879,525,949 shares x $68.77 implies approximately $60.48 billion, consistent with the reported $60.49 billion market cap.
• Self-gate check: summing the 12 non-aggregate institutional register rows (Vanguard 102,463,656 + Capital Group 73,855,890 + BlackRock 73,018,575 + State Street 50,917,469 + Wellington 40,867,860 + MFS 20,030,451 + Geode 19,792,934 + Dodge & Cox 18,303,470 + JPMorgan 14,884,625 + Bank of America 14,599,270 + Norges Bank 11,791,396 + Morgan Stanley 11,169,924 = 451,695,520 shares) plus the insider rows counted per the chart algorithm (Robert M. Blue 212,860 shares in full, plus the aggregate group row reduced by the amount rolling up into it: 1,080,722 - 212,860 = 867,862) gives a total of 452,776,242 shares against 879,525,949 shares outstanding, or 51.48%. This is within the brief's 15 to 55 percent tolerance band, though above the 25 to 45 percent expected range; the elevated total reflects that this register includes 14 rows (12 institutions plus 2 insider rows) rather than a strict top-8 institutional cut, and Dominion Energy's top holders are unusually concentrated (top 3 alone total over 28% of the company). Row count: 14.
