Disclosure Obligations for Listed Companies in Switzerland: What Issuers Need to Know

Companies whose equity securities are listed on the SIX Swiss Exchange benefit from enhanced visibility, liquidity, and access to a broader investor base. However, these advantages come with a robust set of disclosure obligations designed to promote transparency and ensure that investors are able to make informed investment decisions.

Under Swiss capital markets law and the rules of the SIX Swiss Exchange, listed companies are required to make both periodic and ongoing disclosures relating to their business, financial condition, and other material developments. These obligations are a central pillar of Switzerland’s market integrity framework and apply throughout the life of a company’s listing.

Periodic reporting: financial, governance, and sustainability disclosures

SIX-listed issuers must publish an annual report and, where applicable, interim financial statements. Annual reports must include audited financial statements and the corresponding auditor’s report and must be published within four months of the balance sheet date. Interim reports, where required, must be published within three months. These reports must be prepared in accordance with a financial reporting standard recognised by the SIX Regulatory Board, such as IFRS, US GAAP, or Swiss GAAP FER, depending on the applicable reporting standard.

Beyond financial reporting, SIX primary-listed issuers are required to provide detailed corporate governance disclosures on a “comply or explain” basis. These disclosures typically cover areas such as group structure, capital structure, board and executive management, shareholder participation rights, transparency, and information policy. Swiss listed companies must also prepare an annual compensation report setting out remuneration paid to members of the board and executive management.

Larger listed companies that meet defined employee and financial thresholds are additionally required to publish a separate sustainability report in accordance with an internationally recognised standard accepted by the SIX. This report must be published within eight months of the balance sheet date and remain publicly available for five years.

Ongoing disclosure and ad hoc publicity

In addition to periodic reporting, issuers must comply with strict ongoing disclosure obligations, particularly in relation to price-sensitive information. Where a fact arises within the issuer’s sphere of activity and its disclosure would be capable of significantly affecting the market price of the company’s securities, the issuer must make an ad hoc announcement as soon as the essential elements of the event are known.

Ad hoc announcements must be accurate, clear, and complete, and are generally published outside of trading hours to allow market participants adequate time to process the information. While disclosure may be postponed in limited circumstances where immediate publication would prejudice legitimate interests, issuers must ensure strict confidentiality and be prepared to disclose immediately if a leak occurs.

Shareholders, management, and enforcement

Switzerland’s disclosure regime also extends to significant shareholders and senior management. Shareholders who reach, exceed, or fall below specified voting rights thresholds—beginning at 3%—must notify both the issuer and the SIX Disclosure Office. Members of the board of directors and executive committee are required to report transactions involving the issuer’s securities, with the issuer responsible for ensuring timely publication of these management transactions.

Failure to comply with disclosure obligations can result in regulatory sanctions under the SIX self-regulatory framework, including reprimands, fines, suspension of trading, or de-listing. In more serious cases, enforcement action may also be taken under Swiss capital markets legislation, involving FINMA and other competent authorities.

Final thoughts

Switzerland’s disclosure framework reflects a highly developed and well-enforced approach to market transparency. For listed companies, maintaining compliance is not simply a regulatory exercise, but a fundamental component of investor trust and long-term market credibility.
