Allegiance Capital Corporation is a Dallas, Texas-based investment bank that provides merger and acquisition advisory services to privately held, mid-sized companies. It focuses on representing privately owned firms with annual revenue in the range of $20 million to $500 million. Clients typically seek to sell the business, transition leadership, or bring in a financial partner to accelerate growth, and the firm aims to serve as a trusted advisor throughout the process. Founded in 1998 by David Mahmood, Allegiance Capital began as a marketing-first M&A advisory born from his own entrepreneurial experience. It operates with bankers in Dallas, Chicago, New York, and Monterrey, Mexico, and extends its reach through Globalscope Partners. In January 2026, a longtime managing director departed from the firm.
