Ordinary Shares financial

"Ordinary Shares, nominal value 0.001 GBP per share ("Ordinary Shares"), are held in the form of American Depositary Shares"

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.

American Depositary Shares financial

"Ordinary Shares ... are held in the form of American Depositary Shares ("ADSs"). Each ADS represents 1 Ordinary Share."

American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.

weighted average sales price financial

"Represents weighted average sales price. The shares were sold at prices ranging from $252.20 to $252.28."

open-market sale financial

"transaction_action": "open-market sale","transaction_code_description": "Sale in open market or private transaction""

An open-market sale is when a shareholder sells existing shares directly on a public exchange to any willing buyer, rather than through a private deal. Think of it like putting goods on a busy market stall where price is set by supply and demand; for investors it matters because such sales increase available supply, can put short-term downward pressure on the stock price, and signal changes in liquidity or investor confidence.
