NEW YORK Dec 18 (Reuters) - Knight Capital Group agreed to sell itself to Getco Holding Company LLC, beating rival high-speed trading firm Virtu Financial LLC, according to two people close to the negotiations.
Though Virtu had offered an all-cash deal, Getco and its private equity firm General Atlantic increased its offer to above $3.60 a share in cash and stock in the combined company, one source said. Under Getco's plan, Knight Chief Executive Thomas Joyce would give up his role.
A spokeswoman at Knight was not immediately available for comment. (Reporting by Jed Horowitz; Editing by Jan Paschal)
