SIX Exchange Reporting: How to Review Listed Company Disclosures for Swiss Compliance

SIX Exchange Regulation (SER), the self-regulatory body of the SIX Swiss Exchange, establishes and enforces the disclosure and reporting standards for all companies listed on the Swiss exchange. The Listing Rules, the Directive on Ad Hoc Publicity, and the Directive on Corporate Governance together create a comprehensive framework governing what listed companies must disclose, when, and how.

SER actively monitors compliance and has taken enforcement actions including public reprimands, monetary sanctions, and — in extreme cases — suspension of trading. For listed companies and their investor relations, legal, and communications teams, the content of every ad hoc announcement, annual report, and corporate governance disclosure must meet SER's standards — which are precise, time-sensitive, and increasingly focused on content quality.

The Regulatory Framework

Key SIX Disclosure Requirements

Regulation	What It Governs	Content Requirements
Listing Rules Art. 53	Ad hoc publicity	Material price-sensitive information must be disclosed immediately
Directive on Ad Hoc Publicity (DAH)	Ad hoc announcement content	Specific content and dissemination requirements
Listing Rules Art. 49-51	Financial reporting	Annual and semi-annual reports per applicable accounting standards
Directive on Corporate Governance (DCG)	Governance disclosures	Standardized corporate governance report content
Listing Rules Art. 56	Management transactions	Disclosure of transactions by persons with management responsibilities
Disclosure Office Circulars	Significant shareholdings	Content requirements for shareholding notifications

Ad Hoc Publicity: The Core Obligation

Article 53 of the Listing Rules requires that issuers disclose any price-sensitive facts that have arisen within their sphere of activity as soon as they become known. This is the most time-critical content obligation, and the content must:

Be factual, clear, and not misleading
Contain all material information needed to assess the fact
Be published before or simultaneously with any other disclosure
Use SIX's prescribed dissemination channels
Be available in at least one official Swiss language (German, French, or Italian) and optionally in English

Common Disclosure Content Compliance Issues

1. Ad Hoc Announcement Quality

The most frequent compliance issues in ad hoc announcements include:

Incomplete information — omitting material details that investors need to assess the impact
Misleading emphasis — highlighting positive aspects while downplaying negative implications
Timing failures — delaying disclosure to coordinate with marketing messaging
Inconsistent messaging — different information in the ad hoc announcement vs. the press release
Language issues — content available in English but not in an official Swiss language

2. Financial Report Content

Annual and semi-annual reports must comply with both accounting standards (IFRS, Swiss GAAP FER, or US GAAP as elected) and SIX content requirements:

Management commentary must be consistent with financial data
Non-GAAP measures must include reconciliation and explanation
Risk disclosures must be specific and current, not carried forward unchanged
Segment reporting must match the organizational structure described in corporate governance disclosures
Alternative performance measures (APMs) must follow SIX guidance

3. Corporate Governance Report

The DCG requires a standardized corporate governance report addressing:

Section	Required Content
Group structure	Operating structure, listed and non-listed companies, significant shareholders
Capital structure	Authorized/conditional capital, changes in capital, shares, convertible bonds
Board of Directors	Members, other activities, cross-involvement, elections, internal organization
Executive management	Members, other activities, management contracts
Compensation	Compensation report per the Ordinance Against Excessive Compensation (VegueV)
Shareholder rights	Voting, quorum, convocation, agenda items
Change of control	Duty to make an offer, change of control clauses
Auditors	Auditor, supervisory and control instruments, fees
Information policy	Communication channels, calendar, contacts

4. Management Transactions Disclosure

Persons with management responsibilities and persons closely associated with them must report transactions in the issuer's securities. The disclosure content must include:

Identity of the person (or anonymous if aggregate)
Nature of the transaction (purchase, sale, grant, exercise)
Instrument type and quantity
Price and transaction date
Volume threshold disclosures

A Disclosure Content Review Checklist

Building a Disclosure Content Review Process

Swiss-listed companies should implement:

Materiality assessment: Establish clear criteria for when information triggers an ad hoc disclosure obligation
Template management: Maintain approved templates for ad hoc announcements with mandatory content elements
Pre-publication review: AI-assisted scanning for completeness, consistency between narrative and data, and language quality
Multi-language verification: Ensure official language and English versions are substantively equivalent
Post-publication audit: Review published disclosures against SER feedback and enforcement precedents

TeamBench enables Swiss-listed companies to build SIX-specific content reviewers that evaluate disclosure documents against listing rule requirements. Custom criteria can check ad hoc announcement completeness, financial report consistency, corporate governance coverage, and multi-language equivalence — creating a systematic quality gate for every piece of regulated disclosure content.

In a market where SER actively monitors and enforces disclosure quality, and where incomplete or misleading announcements can affect share prices and trigger enforcement proceedings, systematic content review is essential infrastructure for every listed company.
