American depositary shares financial

"The number of Shares reported as beneficially owned by G1 Execution Services, LLC consists of American depositary 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.

beneficially owned financial

"The information required by this Item 4(a) is set forth in Row 9 of the cover page for each Reporting Person hereto and is incorporated herein by reference for each such Reporting Person. The number of Shares reported as beneficially owned by G1 Execution Services, LLC consists of American depositary shares"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

sole voting power financial

"5 | Sole Voting Power 25,694,000.00"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.

shared dispositive power financial

"8 | Shared Dispositive Power 26,532,000.00"

percent of class financial

"Item 4. | Ownership (a) | Amount beneficially owned: ... (b) | Percent of class: 1.4 %"

Percent of class is the portion of a specific category of securities—such as a company’s common shares, preferred shares, or a bond series—that takes part in or approves a corporate action (vote, consent, tender, etc.). Investors watch this number because it reveals how much support or opposition exists within that particular shareholder group; like counting how many members of a club back a proposal, it can determine whether a plan passes or how influence is distributed.

broker-dealers financial

"are affiliated independent broker-dealers, which may be deemed a group"

A broker-dealer is a firm or individual that helps people buy and sell securities and may also trade those securities for its own account. Think of it like a market clerk who can either match a buyer with a seller or sell items from the shop’s shelves; investors rely on broker-dealers to execute trades, custody assets, provide market access and advice, and their actions and fees can affect trade speed, cost and potential conflicts of interest.
