How to strengthen shareholder intelligence and identify shareholders in a company

What are the common sources of shareholder intelligence?

There are many sources of information on share and debt ownership, however these only offer a snapshot of overall investment in a company’s shareholder base. As the data does not usually identify who manages the money and who controls the voting mandate, issuers who pursue bespoke and forensic shareholder identification and analysis, and use shareholder intelligence services are better placed to determine ownership. Sources of intelligence can include:

1. The share register
2. Advisors, brokers and banks
3. Public data
4. Bespoke shareholder analysis
5. Forensic shareholder identification

The share register

The share register is useful for determining domestic institutional and retail shareholders. International (and domestic) shareholders can employ Global Custodian Banks to hold shares on their behalf. Known as “nominee accounts”, these are often misidentified as the shareholder. It’s almost impossible to uncover who is behind “Nominee Accounts”, something that requires a skillset rarely found in-house.

Summary: While the share register is useful for determining institutional and retail shareholders, it cannot identify who is behind “nominee accounts”, therefore doesn’t offer a complete picture.

Advisors, brokers and banks

Banks and brokers used to provide information on share and debt ownership to issuers. However, their influence has reduced, and new market participants now dominate trading volumes. Traditional brokers can no longer offer a broad view of which institutions invest and trade.

Based on 2026 industry analysis of European brokerage activity, the market is heavily dominated by electronic/hybrid brokers for retail and mid-market volumes. However, high-volume, “non-electronic” (high-touch, relationship-based or traditional) services are dominated by established banking institutions and specialised wealth managers. This means that they are increasingly reliant on what they can see from public data.

Summary: While advisors and brokers were once a valuable source of intelligence, their influence has diminished and they have become increasingly reliant on public data.

Public data

Public data is mostly historical, and represents a snapshot of investments in a company. It is dominated by mutual fund disclosures, derived mainly from US 13F Filings. These are only a quarterly snapshot of holdings, and they don’t show what is bought and sold day-to-day. Outside of the US, the filing equivalents are far less frequent, usually six months. This means publicly available data can be up to a year out of date. For fast-moving funds and fast-changing markets, this data is misleading.

Therefore, public data is not a reliable source of information for an issuer trying to determine who holds their shares. The missing data not available in the public domain is what represents the real problem for issuers. Outside of the US, mutual funds represent just 25% of investments. The other classes of investors usually missing include:

• Sovereign wealth funds
• Active and activist funds
• Insurance funds and pension funds
• Hedge funds
• Prime brokerage and proprietary desk positions
• Wealth management
• Stock lending
• Retail

Summary: Public data is historical, and represents a snapshot of investments. This makes it a highly unreliable source for issuers trying to determine true ownership.

Bespoke shareholder analysis

There are different versions of shareholder analysis, with varying degrees of accuracy and depth. From stock surveillance, where public data and Fund Managers’ voluntary declarations are combined to produce a view of ownership, to SRD2 style Custodial position analysis giving a view of who sits at the end of the custody chain.

These methodologies do not link asset ownership to the investment decision-makers. The decision-makers sit at the underlying fund level with the institution and may be externally managed funds. Issuers need to interact and build relationships with the decision-makers, and this has to be at fund level, rather than institutional level. These methodologies do not identify who controls the voting mandate.

Summary: While effective at determining who owns shares, bespoke analysis doesn’t link asset ownership to the decision-makers and voting mandate that IR teams need to target.

Forensic shareholder identification

Forensic shareholder identification gives the issuer the legal right to know who owns shares at a beneficial level – that is, the true share owner when there is a Disclosure Law present in that countries Companies Act or equivalent, or if there are By-Law provisions in that companies Articles.

Based upon the application of regulatory disclosure laws and on the legal provisions within the company by-laws, issuers’ agents can force disclosure at both the custodial and institutional level. This means companies don’t need to rely on interrogating the front office for positions, and uncover all investors, including:

• Mutual, pension and insurance
• Hedge funds, merger arbitrage funds, special situation funds
• Prime brokerage, stock lending accounts
• Market making positions and derivative instruments
• Retail and private equity funds
• Sovereign wealth funds

This enables issuers to identify who ultimately controls the voting power. It will also determine which way investors are likely to vote when trying to pass resolutions or maximising support for strategy, while minimising their risk to hostile takeovers and activist pressure.

Summary: Forensic shareholder identification uses legal disclosure laws to uncover true beneficial ownership at fund level, identifying who controls the voting mandate, and how they are likely to vote, something no other source can provide.
