In Switzerland, shareholder activism and regulatory intervention can both influence a company, but they work through different kinds of authority. Activists use ownership rights, engagement, votes and sometimes litigation to press for change at a particular company. Regulators and exchanges apply statutory and market rules to protect orderly markets and enforce legal obligations. The two can overlap: an activist’s share purchases or coordinated holdings may trigger disclosure duties, and campaigning remains subject to rules on insider trading and market manipulation.
What Swiss company governance covers
Corporate governance concerns the relationship among a company’s shareholders, board of directors and management, and the systems used to manage, verify and monitor senior-management structures and conduct. Switzerland’s SECO SME Portal identifies the Swiss Code of Good Practice for Corporate Governance, published by economiesuisse, and SIX Swiss Exchange’s corporate-governance directives as widely used references. Board members’ legal duties provide a foundation, but governance is broader than compliance alone.
The rules depend on the company and the conduct in question. The Swiss Code of Obligations supplies the general framework for company boards and shareholder rights. For listed companies and market conduct, additional rules include the Financial Market Infrastructure Act (FinMIA, also called FMIA), related ordinances and, for SIX-listed issuers, SIX Listing Rules and directives such as those on ad hoc publicity and corporate governance. This article is a general explanation, not advice on a particular company or transaction.
How activism and regulatory intervention differ
Activism is initiated by shareholders seeking a change in a company. Regulatory intervention is initiated by a public authority acting under a statutory mandate; exchanges also perform front-line market monitoring under self-regulation. Neither mechanism is automatically beneficial or harmful. Investors assess activist proposals in light of their own views and the company’s circumstances, while regulators must act within the powers and duties assigned to them.

| Question | Shareholder activism | Regulatory intervention |
|---|---|---|
| Who initiates it? | A shareholder or group of shareholders. | An exchange or public authority, including FINMA, acting within its monitoring or supervisory role. |
| Where does its authority come from? | Ownership rights, company law and the company’s governing documents. | Statutes, regulations and the applicable supervisory or self-regulatory mandate. |
| What can it involve? | Private engagement, public campaigning, votes, board or shareholder-meeting contests, and, where appropriate, litigation. | Market monitoring, investigations, information demands, administrative rulings and enforcement measures. |
| What is its usual focus? | A particular company and the choices its shareholders are asked to make. | Compliance by market participants and the integrity and orderly functioning of markets. |
| How is it challenged or resolved? | Through company procedures and, where applicable, court proceedings. | Through the relevant administrative appeal route and subsequent judicial review. |
These are broad distinctions, not a checklist of steps available in every case. An activist campaign can attract regulatory scrutiny if it involves regulated conduct, and a regulatory matter may affect a company’s governance without deciding whether the activist’s commercial proposal is sound.
What activists do, and how a campaign can develop
Swiss activist campaigns described in the 2025 Legal 500 and Chambers practitioner guides have addressed governance and board representation, amendments to articles of association, executive compensation, strategy, environmental, social and governance issues, financial performance, and mergers and acquisitions. The guides describe a common—but not inevitable—escalation: an investor builds a stake, approaches management or the board privately, and may campaign publicly for other shareholders’ support if discussions do not resolve the disagreement. Possible later routes include contests at a shareholder meeting or litigation; criminal complaints are relevant only where there is a proper basis for them.
Campaigns differ in visibility and support. Chambers’ 2025 guide says roughly half of campaigns become public and that estimating how often activist demands are met is difficult; these observations do not establish a general success rate. The Legal 500 guide reports that institutional shareholders assess requests case by case, and that public attention tends to be greater when the target is large or well known. It also says Swiss regulators and the legislature have not expressed a general position on activism. Those are the guides’ characterizations, not a rule that every investor or official takes the same view.
Examples reported in 2025 practitioner guides
- Bär & Karrer’s 2025 Legal 500 guide reports 48 activist campaigns against companies of all sizes since 2015. This is a practitioner-guide count, not an official regulator statistic.
- The same guide reports that Steven Wood held approximately 0.5% of Swatch shares before his 2025 board candidacy. It says 79.2% of voting rights rejected the candidacy at Swatch’s May 2025 annual general meeting; the guide also reports that the founding family held 44% of voting rights through voting shares and that Wood received support from more than 60% of bearer-share holders. These figures describe that reported vote, not a general measure of activist support.
- The Legal 500 and Chambers 2025 guides report that Cevian disclosed a 9.4% stake in Baloise in September 2024. The Legal 500 guide says Baloise and Helvetia announced an intended merger of equals shortly before Baloise’s 2025 AGM, and that Cevian sold its stake on the AGM date to Helvetia’s largest shareholder. That reported sequence does not by itself show that activism caused or prevented the merger.
- Chambers’ 2025 guide relays Alvarez & Marsal’s estimate that Switzerland accounted for 13% of European shareholder activism in 2024, compared with 11% in 2023. Because the guide reports this figure second-hand, it should not be treated as an independently verified regulator statistic.
Which disclosure thresholds matter to listed shareholdings?
SIX’s published summary lists the following thresholds for reporting material shareholdings in a listed company. A notification can be triggered when a threshold is crossed either upward or downward.

| Threshold listed in SIX’s summary | Direction that can trigger disclosure |
|---|---|
| 3% | Crossing upward or downward |
| 5% | Crossing upward or downward |
| 10% | Crossing upward or downward |
| 15% | Crossing upward or downward |
| 20% | Crossing upward or downward |
| 25% | Crossing upward or downward |
| 33⅓% | Crossing upward or downward |
| 50% | Crossing upward or downward |
| 66⅔% | Crossing upward or downward |
This is SIX’s published summary, not a complete account of how to calculate or report a holding. Timing, aggregation of holdings, financial instruments and exceptions can affect the analysis. Anyone nearing a threshold should check the current law and exchange rules against the relevant facts rather than assume that the percentage alone settles the question.
When does a public takeover offer become mandatory?
For companies and transactions within the Swiss mandatory-offer regime, FINMA describes the ordinary threshold as 33⅓% of voting rights. A company’s articles may alter that position: SIX explains that the threshold may be raised, for example to 49% (an opt-up), or that the company may opt out of the mandatory-offer regime. The applicable articles and transaction details therefore matter; 33⅓% is not a universal rule for every Swiss company or acquisition.
SIX says these takeover rules apply to Swiss and foreign companies with a primary listing on a Swiss exchange, while specified securities or transaction types are outside their scope. The Swiss Takeover Board reviews mandatory and voluntary public takeover bids. FINMA is the appeal body for its decisions, and FINMA decisions can be contested before the Federal Administrative Court. For a live transaction, the company’s articles, listing status, securities and current law all need to be checked together.

Exchanges monitor securities markets under self-regulatory regimes. FINMA says it investigates suspected legal violations using information from exchanges or its own suspicions, including suspected market abuse and shareholding-disclosure breaches. Its stated tools include demanding information, opening enforcement proceedings, issuing declaratory rulings, disgorging unlawfully obtained gains, publishing rulings and issuing reprimands. FINMA says suspected criminal conduct is referred to the competent prosecution authority.

This role is distinct from deciding a company’s strategy or endorsing an activist’s demands. An activist who buys shares or coordinates with other holders must account for applicable disclosure requirements, while activist activity remains subject to insider-trading and market-manipulation rules. Crossing a disclosure threshold is not, by itself, proof of misconduct; nor does public criticism of a company automatically amount to a regulatory breach.
What changed recently—and what the sources do not establish
On 19 June 2024, the Federal Department of Finance said the Federal Council had opened consultation on proposed FinMIA amendments, with consultation closing on 11 October 2024. The release described proposals intended to support financial-system stability and competitiveness; it does not establish that those proposals became law. Do not treat the consultation announcement as a statement of current legal requirements.
The practitioner guides provide reported campaign and voting examples, not a regulator’s measure of how often activism succeeds. They do not establish a general success rate, and a reported campaign sequence should not be taken as proof that activism caused a company decision. For a specific filing, takeover or campaign, consult the current consolidated statutory text, current SIX rules and the company’s governing documents, and obtain qualified Swiss legal advice where needed.
