CSSF Squeeze-Out and Sell-Out in Luxembourg: Minority Shareholder and Majority Holder Guide
Direct answer
Use CSSF Squeeze-Out and Sell-Out in Luxembourg: Minority Shareholder and Majority Holder Guide when a CSSF-facing question needs a structured file rather than a loose policy summary. It explains understanding the Luxembourg regulatory obligation, supervisory evidence, internal ownership, and escalation points in CSSF Squeeze-Out and Sell-Out in Luxembourg: Minority Shareholder and Majority Holder Guide, then shows how to map the controlling rule, prepare board or compliance evidence, and know when a CSSF-facing specialist should review the file. The later sections connect official sources used, confirm the company and securities perimeter, and identify the majority shareholder status so the next step is easier to judge. Read it before assigning owners or responding to a supervisory request, so the evidence file matches the regulatory question.
The CSSF squeeze-out and sell-out page explains that the Law of 21 July 2012 creates a legal framework for mandatory squeeze-out and sell-out transactions for certain securities of companies whose registered office is in Luxembourg, where securities are admitted or were admitted to trading on a regulated market in one or more Member States, or were offered to the public under the law. The CSSF publishes a list of companies for which information on holdings has been validly notified under Articles 3(1) and 10(1), and companies remain listed for at least twelve months.
This guide is for minority shareholders, majority shareholders, Luxembourg issuers, boards, company secretaries, investor-relations teams, legal advisers and investors checking whether a squeeze-out or sell-out situation may affect their rights. It is not legal advice. Source check date: 20 May 2026.

| Issuer publication | The company concerned publishes information included in the notification where required | Publication proof and holder communication evidence |

The CSSF page gives the contact route for questions but invites persons concerned to refer first to the documentation section.

For prepare a shareholder communication pack, the first question is what fact must be proved. Majority status, securities characteristics, issuer identity, CSSF receipt date, holder communication, valuation report and opposition steps are different facts. Each should have its own document source and owner.
The evidence should be gathered before positions harden. Minority shareholders should not wait until the last day to locate custodian statements or historical notices. Majority holders and issuers should not rely on informal investor-relations knowledge when a formal form, publication or valuation record is required.
A disciplined approach to prepare a shareholder communication pack also protects communication quality. Investors need to know what has happened, what document supports it, what deadline matters and which route is appropriate for questions. The CSSF page gives the contact route for questions but invites persons concerned to refer first to the documentation section.
The best file for prepare a shareholder communication pack is concise: a short memo, the relevant supporting documents, dates, publication evidence, contact log and open issues. It should be possible for a reviewer to understand the process without reconstructing it from press releases and inbox history.

|---|---|---|
| Fact source | Prepare a shareholder communication pack depends on a provable source | Form, issuer notice, CSSF list, custodian proof or valuation document |
| Deadline | Timing can affect rights and responses | Receipt date, publication date and response calendar |
| Communication | Minority and majority parties need a clear record | Publication proof, holder notice and contact log |
