Samsung Electronics Co., Ltd.

What the filings say against what the research found

Every holding above was also resolved directly from EDGAR through a precedence rule: the company's own filing outranks a 13D or 13G, which outranks a 13F, which outranks hand research. A 13F reports only US listed, long, US custodied positions, so it is a floor rather than a level. Where sources disagree the higher one leads and the lower is kept beside it.

No position here shows a material gap between sources.

• No SEC CIK for Samsung Electronics (005930.KS). It is a foreign issuer without a US listing under this ticker, so EDGAR has nothing to ingest. Its curated research is unaffected.

What a reader needs to know to read these numbers

• Currency and conversion: all Korean won figures were converted at 1 USD = 1,416.4245 KRW, the xe.com mid-market rate read on 16 August 2026 at 13:33 UTC. Underlying won figures are given in each method_note. Samsung Electronics common stock closed at KRW 274,500 on 14 August 2026.
• Two different denominators are in use and they are not interchangeable. Korean shareholding tables usually quote a percentage of common shares (보통주), while the largest shareholder change disclosure quotes a percentage of total issued shares including preferred. Samsung Life Insurance's single position of 497,660,185 common shares is 8.51% of common and 7.49% of total issued at the same moment. Every register row above records which denominator applies.
• Preferred shares (005935) are a separately listed, non-voting class with a dividend preference and they trade at a different price from the common. All value_usd figures in the register are for common shares only. Samsung Life Insurance also holds 4,395,000 preferred shares, which are not valued here because no preferred price was fetched.
• Who holds whom, stated in direction rather than flattened. Upward into Samsung Electronics: Samsung Life Insurance holds 8.51% of the common, Samsung C&T holds 5.11%, Samsung Fire & Marine holds 1.49%, Lee Jae-yong holds 1.67% and Hong Ra-hee holds 1.25%. Downward out of Samsung Electronics: Samsung Electronics holds 23.69% of Samsung Electro-Mechanics, 31.22% of Samsung Biologics, 22.58% of Samsung SDS, 19.44% of Samsung SDI and 15.23% of Samsung Heavy Industries.
• The chaebol control chain runs family to Samsung C&T to Samsung Life Insurance to Samsung Electronics. Samsung Electronics does not hold shares in Samsung C&T or Samsung Life, so the ring is not closed at the Samsung Electronics level: control flows one way into the company and one way out into the manufacturing and bio affiliates.
• Affiliate level cross holding confirmed on the pages fetched: Samsung C&T holds 43.06% of Samsung Biologics against Samsung Electronics' 31.22%, so the two Samsung entities together hold about 74.3%. In Samsung SDS, Samsung C&T holds 17.08% and Lee Jae-yong personally holds 9.20% alongside Samsung Electronics' 22.58%. Samsung SDI holds 3,173,594 shares, 0.36%, of Samsung Heavy Industries.
• Disagreement recorded, not overwritten. The Korea Herald reported on 20 March 2026 that Samsung Life would sell 6,244,658 Samsung Electronics shares and Samsung Fire 1,091,273 shares in a block deal, taking Samsung Life from 8.51% to 8.41% and Samsung Fire from 1.49% to 1.47%, in order to stay under the 10% cap on a financial company's stake in a non-financial affiliate after Samsung Electronics cancelled 73.36 million treasury shares. The 8 June 2026 largest shareholder disclosure still reports Samsung Life at 497,660,185 common shares, and that count divides exactly to the 7.49% of total issued shares the disclosure states, so the June filed figure is used above and the March report is flagged here.
• Market capitalisation does not reconcile cleanly and the reader should treat it as approximate. stockanalysis.com reports a market cap of KRW 1,742.17 trillion and 6.58bn shares outstanding on 14 August 2026, but 1,742.17 trillion divided by the KRW 274,500 common close implies 6.35bn shares, while the percentages on the Korean shareholding pages imply a common base of about 5.847bn shares (4,424,152,717 float at 75.67%, and 1,151,309,872 at 19.69%, both give roughly 5.847bn). The USD market cap above is the stockanalysis won figure converted at 1,416.4245.
• Share counts in share_classes are the issued totals published on Samsung's own listing information page as of Q1 2026: 5,919,637,922 common and 815,974,664 preferred, 6,735,612,586 in total. These appear to predate the 73.36 million share treasury cancellation referenced in the March 2026 Korea Herald report, which is why the register percentages imply a smaller current common base. shares_outstanding is left null rather than pick between the two.
• The affiliate stakes carry old last change dates in the Korean disclosure tables (Samsung Electro-Mechanics 18 Sep 2000, Samsung SDS 14 Nov 2014, Samsung SDI 10 Apr 2025, Samsung Biologics 24 Nov 2025). That is a record of stability, not of stale data: the share count is the current one and the date is when it last moved.
• The Samsung Heavy Industries disclosure page also lists a second Samsung entity at 18,150,855 shares, 2.06%, which the page rendering labelled ambiguously. It is not counted in the Samsung Electronics holding above, which uses only the 134,027,281 shares attributed to Samsung Electronics as largest shareholder.
• Samsung Electronics files in Korea, not with the SEC. There is no CIK and no 13F, so none of the holdings above come from a US filing. The register and holdings both derive from Korean disclosure (DART and KIND aggregated by WiseReport) and Korean press reports of those disclosures.
