treasury shares financial

"of which 12,130,560 are held as treasury shares"

Treasury shares are a company’s own stock that it has repurchased and keeps on its books instead of canceling or leaving in the hands of outside investors. Think of them like coupons a business puts back in a drawer: they don’t vote or receive dividends while held, but they can be reissued later for employee pay or fundraising. For investors this matters because buybacks change the number of shares that count toward earnings and ownership, can boost per‑share metrics, and use corporate cash that might otherwise go to growth or dividends.

Market Abuse Regulation regulatory

"In accordance with Article 5(1)(b) of Regulation (EU) No 596/2014 as it applies in the UK (the Market Abuse Regulation)"

Market abuse regulation consists of laws and rules designed to prevent dishonest or manipulative practices in financial markets. It aims to ensure fair and transparent trading, so investors can trust that markets operate honestly, much like rules that keep a game fair. By reducing unfair advantages, it helps protect investor confidence and promotes healthy, efficient markets.

Disclosure Guidance and Transparency Rules regulatory

"to notify their interest, or a change to their interest, in Haleon under the FCA's Disclosure Guidance and Transparency Rules"

Disclosure guidance and transparency rules are the standards and regulations that require companies to share clear, timely information about their finances, risks, operations and material events. They matter to investors because consistent, honest reporting is like a car’s dashboard — it reveals the data you need to judge safety and performance and make informed buying or selling decisions. Strong disclosure reduces surprises and helps keep markets fair and efficient.
