New York Community Bancorp’s merger with Flagstar Bancorp closed on December 1, 2022, combining a New York multi-family lender with a national mortgage platform in an all-stock deal originally valued at about $2.6 billion. What followed is the part most people are actually asking about: a second acquisition of failed Signature Bank, a commercial real estate crisis, a $1.05 billion rescue investment led by former Treasury Secretary Steven Mnuchin, new leadership, the sale of the mortgage business, and a corporate rebrand. The holding company is now called Flagstar Financial, Inc. and trades on the NYSE as FLG. It reported its first profitable quarter since the crisis in the fourth quarter of 2025.
How the Merger Was Structured
NYCB announced the acquisition on April 24, 2021 as an all-stock strategic merger.1PR Newswire. New York Community Bancorp, Inc. To Acquire Flagstar Bancorp, Inc. in an All-Stock Strategic Merger When the deal closed on December 1, 2022, Flagstar merged into NYCB and the combined bank began operating under the Flagstar Bank, N.A. name.2Flagstar Bancorp, Inc.

The structure was more than a rebranding exercise. Flagstar converted from a federal savings bank to a national bank, the old New York Community Bank was merged into it, and the OCC became the primary federal regulator in place of the FDIC.3Office of the Comptroller of the Currency. Conditional Approval 1299 – Flagstar Bank Conversion and Merger The strategic logic was diversification. NYCB had decades of concentration in New York City multi-family lending, and Flagstar brought a national mortgage origination and servicing operation, warehouse lending, and a commercial bank.
The Signature Bank Acquisition That Followed
Four months after closing the Flagstar deal, the combined bank made a much bigger move. On March 20, 2023, Flagstar Bank, N.A. acquired substantially all of Signature Bridge Bank’s assets and deposits in an FDIC-assisted transaction after Signature collapsed during the regional banking crisis. The deal brought roughly $34 billion in deposits, $13 billion in commercial and industrial loans, and $25 billion in cash.4Flagstar Bank, N.A. New York Community Bancorp, Inc. Through Its Bank Subsidiary, Flagstar Bank, N.A., Acquires Certain Assets and Assumes Certain Liabilities of Signature Bridge Bank From the FDIC Flagstar took over about 30 branches in the New York City metro area and several on the West Coast, along with Signature’s wealth management and broker-dealer operation. It did not assume Signature’s crypto-related assets or digital banking deposits.
This second deal pushed the bank past $100 billion in total assets. That threshold matters: crossing it triggers significantly tougher capital, liquidity, and stress-testing requirements. The heightened scrutiny that came with it is what eventually forced the deeper look at the loan book.
What It Meant for Customer Accounts
Legacy customers of all three banks (the original New York Community Bank, the original Flagstar Bank, and Signature Bank) were eventually consolidated onto a single operating system under the Flagstar Bank name. All 419 branches were rebranded, and the online banking platforms merged into one app and website.5Flagstar Bank, N.A.

Routing numbers still split by legacy bank. If you came from New York Community Bank or the original Flagstar, your routing number is 226071004. If you came from Signature, it’s 026013576. Check yours before setting up direct deposits or automatic payments. Account numbers for deposits and loans generally stayed the same through the conversion, but new checks and payment forms should carry the correct Flagstar routing number.

Deposit insurance carried through everything. All deposits at Flagstar Bank, N.A. are FDIC-insured up to $250,000 per depositor, per insured bank, for each account ownership category.7FDIC. Understanding Deposit Insurance Insured deposits were not at risk at any point during the merger, the Signature acquisition, or the later capital crisis.
Why the Combined Bank Ran Into Trouble
NYCB had built one of the country’s largest portfolios of loans on multi-family apartment buildings, heavily concentrated in rent-stabilized New York City housing. New York’s Housing Stability and Tenant Protection Act of 2019 sharply limited rent increases on stabilized units, even after major renovations. Landlords who had borrowed on the assumption of rising rental income found their revenue capped while costs and interest payments climbed.
As rates rose from roughly 3% to 6–7% between 2022 and 2024, many borrowers couldn’t refinance because their buildings were worth less than the outstanding mortgages. Some properties lost as much as 80% of their pre-2019 value. By mid-2024, a review of 80% of the multi-family portfolio showed delinquencies up 767% and charge-offs up 590%, driving the credit loss allowance to $1.2 billion, more than double the prior year.
The trouble surfaced publicly on January 31, 2024, when NYCB reported a surprise fourth-quarter loss with $552 million in credit-loss provisions and cut the quarterly dividend from $0.17 to $0.05 per share, a drop of about 71%. In late February 2024, the bank disclosed a $2.4 billion goodwill impairment charge and acknowledged “material weaknesses” in its internal controls over the loan review process. The stock cratered.
The Rescue Investment and New Leadership
On March 7, 2024, NYCB announced a $1.05 billion equity investment from a group of outside investors. Liberty Strategic Capital, led by former Treasury Secretary Steven Mnuchin, committed $450 million. Hudson Bay Capital invested $250 million, Reverence Capital Partners put in $200 million, and Citadel Global Equities and other institutional investors and company management covered the rest.8Flagstar Bank, N.A. New York Community Bancorp, Inc. Announces Over $1 Billion Equity Investment Existing shareholders paid dearly for the rescue. New investors received shares at $2.00 each, and their combined stake represented roughly 41.4% of outstanding shares on a fully diluted basis.
Leadership was replaced. Joseph Otting, who served as the 31st Comptroller of the Currency from 2017 to 2020, was named President and CEO on April 1, 2024, replacing Alessandro DiNello. By June 2024, Otting also became Executive Chairman, and DiNello left the board entirely.9Flagstar Bank, N.A. Joseph M.

Asset Sales, Reverse Split, and Rebrand
Under Otting, the bank shed major business lines to shrink and simplify. The largest sale was Flagstar’s residential mortgage servicing and third-party origination business, which went to Mr. Cooper Group for approximately $1.3 billion in cash and closed on November 1, 2024.10Flagstar Bank, N.A. Flagstar Bank Closes on the Sale of Its Mortgage Servicing and Third-Party Origination Business to Mr. Cooper That was a sharp pivot from the original merger logic, since the mortgage platform was a big reason NYCB wanted Flagstar in the first place. The bank also sold roughly $5.9 billion in mortgage warehouse loans to JPMorgan Chase at par, with about $200 million more to follow.11Flagstar Bank, N.A.

Shareholders saw two visible changes on top of the dilution. A one-for-three reverse stock split took effect on July 11, 2024, converting every three shares into one.12Flagstar Bank, N.A.

Where Things Stand Now
The restructuring is working, slowly. Flagstar Financial reported a full-year 2025 net loss of $177 million, an improvement from the $1.1 billion loss in 2024. The fourth quarter of 2025 was the first profitable quarter since the crisis began, with net income of $0.05 per diluted share.14Flagstar Bank, N.A. Flagstar Bank Returns to Profitability in Fourth Quarter 2025 The common equity tier 1 ratio was 12.83% at December 31, 2025, well above the “well capitalized” regulatory threshold. Problem loans remain elevated. Non-performing loans stood at 4.90% of loans held for investment, and net charge-offs for the year totaled $351 million. The multi-family and commercial real estate exposures will take years to work through.
Flagstar Bank, N.A. operates as a national bank with the OCC as its primary federal regulator, and it is also regulated by the Federal Reserve and examined by the FDIC.15Federal Financial Institutions Examination Council.
