Communiqué
The CSSF's January 2026 enforcement report documents the results of its 2025 examination campaign on 2024 financial and non-financial disclosures by issuers under Luxembourg's Transparency Law. This publication is critical for compliance professionals because it reveals systematic compliance gaps across financial reporting (IFRS), sustainability reporting (ESRS), and Alternative Performance Measures (APMs), with 27% of enforcement decisions resulting in injunctions for non-compliance.
What Changed

The CSSF imposed a €10,000 administrative fine on BigRep SE on 12 January 2026 for failing to publish its half-yearly financial report as of 30 June 2025, as required under Article 4 of Luxembourg's Transparency Law of 11 January 2008 (as amended). This enforcement action underscores the CSSF's rigorous supervision of periodic disclosure obligations for issuers with Luxembourg as their home Member State, serving as a reminder of the consequences for non-compliance with transparency requirements. Compliance professionals should note this as evidence of ongoing CSSF scrutiny on timely reporting, with potential fines scaled based on circumstances per Article 26a.
#
What Changed
This is not a regulatory change or new requirement but an enforcement of existing obligations under the Transparency Law of 11 January 2008 (as amended), specifically Article 4, which mandates issuers to publish half-yearly financial reports, including effective dissemination, storage on the Officially Appointed Mechanism (OAM), and filing with the CSSF. No new rules are introduced; the sanction reinforces the unchanged deadlines and processes for periodic information publication, with the CSSF

Urgency: Medium – This matters as a specific enforcement example in CSSF's ongoing verification of periodic information publication, signaling heightened scrutiny rather than a systemic shift.

This CSSF publication, dated January 12, 2026, identifies the specific population (likely a firm or individual) subject to an enforcement action, such as an administrative sanction, as part of the CSSF's transparency in supervisory measures. It matters because it signals CSSF's active enforcement priorities, potentially in areas like AML or reporting failures, enabling firms to assess similar risks in their operations and strengthen compliance to avoid parallel actions. Published amid rising focus on financial crime typologies like sexual extortion, it underscores the regulator's commitment to public accountability.
#
What Changed
No new regulatory changes or requirements are introduced in this publication, as it is an enforcement notice rather than a circular or guideline. It serves as a disclosure of an ongoing or concluded enforcement case, aligning with CSSF's practice of publishing sanction details to deter non-compliance and inform the market, without altering existing rules.

Administrative sanction imposed on the alternative investment fund manager Premium Capital Management (“AIFM”)
The CSSF imposed a €10,000 administrative fine on 11 September 2025 against alternative investment fund manager (AIFM) Premium Capital Management for failing to submit its annual financial crime questionnaire by the 4 April 2025 deadline, breaching the cooperation obligation under Article 5(1) of Luxembourg's AML/CFT Law of 12 November 2004. This enforcement action underscores the CSSF's strict enforcement of AML reporting duties, signaling heightened scrutiny on timely supervisory cooperation amid ongoing AML risks in Luxembourg. Compliance teams should view this as a reminder of the low tolerance for even administrative lapses, with potential for escalated fines in repeat cases.
#
What Changed
This is not a regulatory change but an enforcement precedent under existing rules: non-compliance with Article 5(1) of the AML/CFT Law, which mandates annual submission of a financial crime questionnaire ("Questionnaire") to the CSSF. The fine was calculated per Articles 8-4(1), 8-4(2)(f), and 8-4(3)(a), considering circumstances under Article 8-5(1). Publication followed Article 8-6(1) after a proportionality assessment, confirming no market stability risks. No new requirements were introduced;
What You Need To Do
- Immediately review internal processes for annual Questionnaire submission, ensuring calendar invites and automated reminders for the 4 April deadline (covering prior year-end data)

The CSSF imposed a **€10,000 administrative fine on Sunbricks GP S.à r.l.**, an alternative investment fund manager, for failing to submit a mandatory annual financial crime questionnaire by the April 4, 2025 deadline, despite two formal reminders. This enforcement action demonstrates the CSSF's strict approach to cooperation obligations under Luxembourg's anti-money laundering and counter-terrorist financing (AML/CFT) framework and signals that non-submission of required compliance documentation—even without evidence of underlying financial crime—triggers regulatory penalties.
What Changed
This is not a regulatory change but rather an enforcement action clarifying existing obligations:
Mandatory Annual Questionnaire Requirement: All professionals supervised, authorized, or registered by the CSSF must submit an annual questionnaire on financial crime by April 4 each year, covering the preceding calendar year.

Repeal of Circular CSSF 19/731 regarding the documents to be submitted on an annual basis by credit institutions.
Circular CSSF 25/902 repeals Circular CSSF 19/731 (as amended by Circular CSSF 19/710), which previously detailed annual document submission requirements for credit institutions, shifting to a dynamic list published on the CSSF website.
