The Regulatory News Service, or RNS, disseminates regulatory and non-regulatory information on behalf of UK businesses and publicly traded companies. The RNS, which is part of the London Stock Exchange (LSE), provides businesses with information that can assist them in meeting their disclosure obligations.

A Regulatory News Service (RNS) is a platform used by publicly listed companies to disclose important, market-sensitive information to investors, regulators, and the public. It is a key component of financial transparency, ensuring that all investors have equal access to critical updates that may affect a company's stock price.

Announcements made through an RNS can include earnings reports, changes in leadership, mergers and acquisitions, or major business developments. In the UK, the London Stock Exchange operates the RNS as part of its listing requirements.

The goal of an RNS is to maintain market integrity by preventing insider trading and ensuring timely, accurate communication of information, enabling investors to make informed decisions based on the latest company developments.
