"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.

17 CFR 240.12d2-2 regulatory

"Pursuant to 17 CFR 240.12d2-2(b)"

A U.S. Securities and Exchange Commission rule that describes the conditions and procedural steps for a security to be removed from public registration or reporting under the Securities Exchange Act of 1934. For investors, it matters because it explains when a company’s shares can stop being subject to regular disclosure and exchange listing rules — similar to knowing when a publicly tracked product will be discontinued and no longer send updates, which affects transparency and liquidity.
