Initial public offering (IPO)

An initial public offering is the process by which a company offers shares to the public for the first time and usually seeks admission to trading on a stock exchange. In Switzerland, an IPO typically requires a compliant prospectus, corporate approvals, due diligence, underwriting arrangements, listing documentation and ongoing obligations after trading begins. The process also involves marketing restrictions, financial reporting and governance expectations. Cross-border offerings may trigger foreign securities laws, so Swiss issuers and selling shareholders often structure the offer by jurisdiction and investor category.
