Muriel Siebert & Co., Inc., a wholly owned subsidiary of Siebert Financial Corp. (Nasdaq: SIEB), today announced that Charles D. Sorkin and Dominic A. Antoniello have joined its Capital Markets Group as managing directors, effective immediately. Mr. Sorkin joins Siebert as an Investment Banker focused on Debt Capital Markets, while Mr. Antoniello joins the firm in the role of Taxable Fixed-Income Sales.

“Charles Sorkin and Dominic Antoniello are both highly experienced veterans who further strengthen our capital markets team, as we provide excellent value and service to our esteemed issuer and institutional clients,” said Muriel F. "Mickie" Siebert, president, chief executive and chairwoman of Siebert Financial Corp. "Their extensive customer relationships and sound knowledge of the fixed-income markets will enable our continued expansion while providing the excellent service our valued clients have come to expect from us.”

Mr. Sorkin is a seasoned capital markets professional with an extensive background of more than 15 years in the taxable fixed income market, five years of it at Siebert. Most recently he was with Magna Securities in New York. Mr. Sorkin is known for his customer-focused approach to both securities issuers and institutional investors, and will extend that approach to Siebert’s securities-issuing clients, while offering the comprehensive focus that they have come to expect from Siebert Capital Markets.

Mr. Antoniello joins Siebert as a Fixed-Income Sales Trader. Most recently he was Managing Director and Head of Fixed-Income at Magna Securities. Mr. Antoniello has more than 35 years of fixed-income experience and possesses extensive knowledge of U.S. Treasury, federal agency, corporate, municipal and money market instrument securities markets.

Mr. Antoniello enhances a trading desk of veteran professionals in the Siebert Capital Markets (SCM) division, which provides high-quality brokerage services to institutional clients and investment banking services to corporations. Backed by the latest information technology and systems, its traders and investment bankers offer value-added services to some of the nation’s largest investment managers, corporations and public retirement systems.

The SCM division continued to expand its business in 2009, acting as co-manager or underwriter in more than $115 billion of global debt and equity offerings. SCM participated in debt and equity transactions for dozens of U.S. companies in 2009, including Bank of America Corp., Boeing, Citigroup Inc., Dominion Resources, Inc., Ford Motor Company, Hyatt Corporation, JPMorgan Chase & Co., Morgan Stanley and PepsiCo, Inc. As a result of these underwritings, Siebert retail clients have access to new issue debt and equity securities including corporates, preferreds and more. On the institutional brokerage side, the trading department continues to bolster its electronic execution capabilities, resulting in a significant increase in its corporate share repurchase business.
