Insights

Beneficial‑ownership disclosure clarifies group control links and ADS mechanics.

The Schedule 13G maps voting and dispositive powers across the Slim Family, GFI and affiliated foundations, showing collective influence without asserting sole ownership. It cites an outstanding share base of December 31, 2025 for percent calculations.

Watch subsequent filings for any change-of-control statements or conversions between ADSs and underlying Ordinary Shares; timing of such items is not included here.

Positions are modest versus total float; disclosure reduces uncertainty about holder structure.

The largest single reported line is 45,465,533 Ordinary Shares for Fundacion Carlos Slim; collectively cited positions equal 5.1% per the filing. The statement explains ADS ratio (2.5 Ordinary Shares per ADS), which matters for float and voting mechanics.

Further market impact depends on whether these holdings are tradable ADSs or subject to foundation/trust constraints; the filing disclaims some economic ownership claims.

Ads are paid promotional messages a company places across media — online, on TV, in print, or on social platforms — to attract customers, explain products, or shape public perception. For investors, ads matter because they drive sales growth, affect how much a company must spend to win customers, and influence brand strength and long-term value. Ads can also create regulatory or reputational risk if claims are misleading, which can affect profits and stock price.
shared dispositive power regulatory
"Shared Dispositive Power 40,628,598.00"
beneficially owned regulatory
"Amount beneficially owned: Calculations of the percentage of the Ordinary Shares underlying ADSs beneficially owned"
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.
Schedule 13G regulatory
"This statement is filed pursuant to Rule 13d-2(b) under the U.S. Securities Exchange Act"
A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
