"registration under Section 12(b) of the Securities Exchange Act of 1934"

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.
