Flagstar Bank
About Flagstar Bank
Flagstar Bank, National Association is a major American regional bank providing consumer banking, commercial banking, private banking, wealth services, mortgages and other lending products. The bank currently operates approximately 340 locations, including roughly 320 retail locations and 20 private banking offices, with major concentrations in the New York and New Jersey metropolitan region and the upper Midwest. As of June 30, 2026, Flagstar reported approximately $87.7 billion in assets, $61 billion in loans, $67.5 billion in deposits and $8.1 billion in stockholders’ equity.
The modern Flagstar organization combines two important banking histories. The current bank traces its corporate roots to Queens County Savings Bank, founded in 1859 in Queens, New York, while the original Flagstar banking franchise traces its origins to First Security Savings Bank, established in Michigan in 1987 and renamed Flagstar in 1996. New York Community Bancorp acquired Flagstar Bancorp in 2022, and the combined organization later adopted the Flagstar name.
A significant corporate restructuring took effect on October 17, 2025, when former holding company Flagstar Financial, Inc. merged into Flagstar Bank, N.A. and the bank became the surviving publicly traded reporting company. Current SEC filings identify 102 Duffy Avenue, Hicksville, New York 11801 as Flagstar Bank’s principal executive offices. Flagstar’s common stock trades on the New York Stock Exchange under ticker symbol FLG, and the bank reported 5,631 employees at December 31, 2025.
