"FORM 25 NOTIFICATION OF REMOVAL FROM LISTING"

A Form 25 is an official filing with the U.S. Securities and Exchange Commission used to remove a company's stock or other security from a national exchange list. Investors should care because delisting often means less visibility, lower trading volume and wider price swings—similar to a product moving from a major supermarket to a small local market, which can make buying, selling and valuing the security more difficult.

American Depositary Shares market

"American Depositary Shares, each representing 10 ordinary shares"

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.

Section 12(b) regulatory

"REMOVAL FROM LISTING AND/OR REGISTRATION UNDER SECTION 12(b)"

Section 12(b) of the U.S. Securities Exchange Act requires securities listed on a national stock exchange to be registered with the U.S. Securities and Exchange Commission (SEC) and to follow regular public reporting and disclosure rules. For investors, a 12(b) listing generally means more routine financial updates, regulatory oversight and easier buying and selling—like a storefront that must display its inventory and prices, making it simpler to inspect and trade the product.
