Insights

Institutional Ownership Analyst

Large asset manager reports a passive 4.7% stake in KB Financial.

Capital Research Global Investors is disclosed as beneficial owner of 17,488,330 shares, with sole voting power over 17,408,516 shares. The filing uses Schedule 13G/A language indicating passive/Section 13 reporting rather than an active control schedule.

The reported stake is below 5% threshold; subsequent holdings or trading activity will be revealed in later filings if ownership crosses thresholds or changes. Timing and cash‑flow treatment are not provided in the excerpt.

Corporate Governance Specialist

Filing documents ownership and voting/dispositive splits without indicating activism.

The amendment lists specific sole voting and sole dispositive powers—useful for governance mapping—and notes inclusion of 60,488 Depository Receipts within the total share count. The signature line shows the filing was executed by a Capital Research officer on 05/11/2026.

Because the stake is under 5.0%, this is routine disclosure; any change above reporting thresholds would require updated disclosure.

4 terms

Schedule 13G/A regulatory

"Amendment No. 1 and Schedule 13G/A ownership amendment"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

Beneficially owned financial

"CRGI is deemed to be the beneficial owner of 17,488,330 shares"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

Depository Receipts market

"Shares reported include 60,488 Depository Receipts"

A depository receipt is a tradable certificate issued by a bank that represents ownership of shares held in a foreign company, letting investors buy and sell those shares on their local stock market without dealing with the foreign exchange and custody details. Think of it as a local receipt for a piece of a foreign company kept in a secure vault abroad; it matters because it makes international investing easier, often increases liquidity, and can affect dividend payments and currency risk.

Sole dispositive power regulatory

"Sole power to dispose or to direct the disposition of: 17,488,330"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.
