Siebert Financial Corp. Completes Path to Full StockCross Ownership, Targeting $1B Asset Growth

Siebert Financial Corp. (NASDAQ:SIEB) is making a significant move in the brokerage space by moving toward complete acquisition of StockCross Financial Services, Inc. The deal marks a strategic expansion that will reshape Siebert’s service portfolio and market presence.

Transaction Details and Timeline

The company has committed to acquiring the remaining 85% stake in StockCross, which will grant Siebert full ownership of the clearing broker-dealer. This follows Siebert’s initial 15% investment made in Q1 2019. Once regulatory approval comes through, StockCross will be integrated into Muriel Siebert & Co., Inc., Siebert’s existing broker-dealer subsidiary.

Strategic Business Expansion

This acquisition substantially broadens Siebert’s operational capabilities. The deal brings four new revenue streams into the fold: market-making operations, equity stock plan services, IRA custodianship, and securities lending. These additions fill gaps in Siebert’s current business model and create immediate revenue opportunities.

The financial footprint is equally impressive—Siebert will add $1 billion in customer assets to its balance sheet alongside three retail branch locations and 45 new team members. This positions the company to achieve meaningful economies of scale that have been elusive in the competitive brokerage environment.

Integration and Growth Synergies

Management sees clear synergy potential. By combining operational teams and expertise, Siebert gains the capability to serve additional customer segments while enhancing service depth. The expanded personnel base and management bench strength enable the company to strengthen client relationships across multiple touchpoints.

Gloria E. Gebbia, controlling shareholder and board member of Siebert, framed the deal as accelerating growth while delivering increased value across stakeholder groups—clients, shareholders, and employees alike.

Market Context

Siebert operates through multiple subsidiaries handling distinct business lines: retail discount brokerage via Muriel Siebert & Co., investment advisory services through SiebertAdvisorNXT, insurance operations under Park Wilshire Companies Inc., and robo-advisory technology via KCA Technologies. The company maintains 13 retail branches nationally and headquarters in New York City.

StockCross, established in 1971, operates as one of the nation’s larger privately-held brokerage firms, with branch locations across the country and a Beverly Hills headquarters. The firm has built its reputation on delivering comprehensive financial services including trading, clearing, custody, and specialized plan administration.

The transaction remains subject to regulatory approval before closing.
