Quiet Period

When a company sells shares on the stock exchange for the first time, buyers must not be misled. That’s why there are rules about which information a company may disclose and when. The quiet period is one such rule: a window of time during which management and employees must remain publicly silent. They may not promote their own stock and may not mention new figures or forecasts. Everything investors are supposed to know instead appears in an official, audited document. The term comes from English securities regulation and literally means something like a “quiet phase.”

Why everyone must stay silent before an IPO

An IPO is a sale with a strong incentive to exaggerate. The founders want the highest possible price for their shares. Without rules, the CEO could scatter generous promises in interviews shortly before the sale. The quiet period prevents this. Anyone wanting to invest should base their decision on the prospectus, i.e. the audited document containing all figures and risks.

The second reason is equal treatment. On the stock market, information is worth money. If an analyst or a major investor learns three days earlier that business is going poorly, they can exit cheaply. Small investors would then be structurally at a disadvantage. Regulators such as the US Securities and Exchange Commission (SEC) or Germany’s BaFin therefore keep a close eye on such deadlines.

Violations are no small matter. In 2012, an interview with Google managers shortly before the IPO caused trouble, and the date had to be postponed. There was also a dispute at Facebook, where analysts told individual clients about lowered expectations. Such cases regularly end in lawsuits and fines.

Which deadlines apply and what is prohibited

Two variants must be distinguished. The first concerns the IPO. It begins as soon as the company starts preparing to go public and usually ends around 25 days after the first day of trading. During this time, the accompanying banks are also not allowed to publish any analyses of the company.

The second variant applies to companies that have long been publicly listed. They voluntarily remain silent for a few weeks before each quarterly report. The reason is simple: internally, the figures are already known, but they have not yet been published. Any statement could inadvertently reveal these figures. Two to four weeks is common, as set out in an internal policy.

Anything that provides new insights is prohibited: revenue forecasts, comments on order books, appearances at investor conferences. Normal business remains permitted. A company may continue to present products and issue press releases about contracts. It’s also important to distinguish this from the lock-up period. That period doesn’t prohibit speaking but selling: existing shareholders are often barred from disposing of their shares for 180 days.

Quiet periods in tech IPOs and in the news

Anyone reading business news usually encounters the term in connection with technology companies. One example: after the IPO of an AI chip maker, it suddenly turns out that a dozen banks issued a buy recommendation at the same time. That’s no coincidence. The quiet period had just ended, and everyone was allowed to start on the same day. Such days often move the share price significantly.

The opposite also shows up in reports. When a journalist contacts a company and the answer is “no comment due to the quiet period,” this is exactly the rule being referred to. It also applies to employees. At some companies, staff receive an email before quarterly results reminding them to stay silent on social media.

A common misconception: the quiet period does not mean a company is allowed to withhold bad news. Price-relevant events such as a recall or a collapsed major contract must still be reported immediately. Silence only applies to what would soon be announced officially anyway. In practical terms, this means that during these weeks the flow of news is thin, and rumors have an easier time spreading.
