2021 Annual Meeting of Shareholders May 26, 2021 Exhibit 99.1

Disclaimer Cautionary Note Regarding Forward-Looking Statements This presentation includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended with respect to New York Community Bancorp, Inc.’s (“NYCB”) and Flagstar Bancorp Inc.’s (“Flagstar”) beliefs, goals, intentions, and expectations regarding revenues, earnings, loan production, asset quality, capital levels, and acquisitions, among other matters; our estimates of future costs and benefits of the actions we may take; our assessments of probable losses on loans; our assessments of interest rate and other market risks; and our ability to achieve our financial and other strategic goals. Forward‐looking statements are typically identified by such words as “believe,” “expect,” “anticipate,” “intend,” “outlook,” “estimate,” “forecast,” “project,” “should,” and other similar words and expressions, and are subject to numerous assumptions, risks, and uncertainties, which change over time. These forward-looking statements include, without limitation, those relating to the terms, timing and closing of the proposed transaction. Additionally, forward‐looking statements speak only as of the date they are made; NYCB and Flagstar do not assume any duty, and do not undertake, to update such forward‐looking statements. Furthermore, because forward‐looking statements are subject to assumptions and uncertainties, actual results or future events could differ, possibly materially, from those indicated in such forward-looking statements as a result of a variety of factors, many of which are beyond the control of NYCB and Flagstar. The factors that could cause actual results to differ materially include the following: the occurrence of any event, change or other circumstances that could give rise to the right of one or both of the parties to terminate the definitive merger agreement between NYCB and Flagstar; the outcome of any legal proceedings that may be instituted against NYCB or Flagstar; the possibility that the proposed transaction will not close when expected or at all because required regulatory, shareholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all, or are obtained subject to conditions that are not anticipated; the ability of NYCB and Flagstar to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; the risk that any announcements relating to the proposed transaction could have adverse effects on the market price of the common stock of either or both parties to the proposed transaction; the possibility that the anticipated benefits of the proposed transaction will not be realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors in the areas where NYCB and Flagstar do business; certain restrictions during the pendency of the proposed transaction that may impact the parties’ ability to pursue certain business opportunities or strategic transactions; the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; diversion of management’s attention from ongoing business operations and opportunities; the possibility that the parties may be unable to achieve expected synergies and operating efficiencies in the merger within the expected timeframes or at all and to successfully integrate Flagstar’s operations and those of NYCB; such integration may be more difficult, time consuming or costly than expected; revenues following the proposed transaction may be lower than expected; potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the proposed transaction; NYCB’s and Flagstar’s success in executing their respective business plans and strategies and managing the risks involved in the foregoing; the dilution caused by NYCB’s issuance of additional shares of its capital stock in connection with the proposed transaction; and other factors that may affect future results of NYCB and Flagstar; [uncertainty as to the extent of the duration, scope, and impacts of the COVID-19 pandemic on Flagstar, NYCB and the proposed combination;] and the other factors discussed in the “Risk Factors” section NYCB’s Annual Report on Form 10‐K for the year ended December 31, 2020 and in other reports NYCB files with the U.S. Securities and Exchange Commission (the “SEC”), which are available at http://www.sec.gov and in the “SEC Filings” section of NYCB’s website, https://ir.mynycb.com, under the heading “Financial Information,” and in Flagstar’s Annual Report on Form 10-K for the year ended December 31, 2020 and in Flagstar’s other filings with SEC, which are available at http://www.sec.gov and in the “Documents” section of Flagstar’s website, https://www.flagstar.com//, under the heading “Investor Relations.”

Appendix

While average stockholders’ equity, average assets, return on average assets, and return on average stockholders’ equity are financial measures that are recorded in accordance with U.S. generally accepted accounting principles ("GAAP"), average tangible stockholders’ equity, average tangible assets, return on average tangible assets, and return on average tangible stockholders’ equity are not. Nevertheless, it is management’s belief that these non-GAAP measures should be disclosed in our SEC filings, earnings releases, and other investor communications, for the following reasons: Average tangible stockholders’ equity is an important indication of the Company’s ability to grow organically and through business combinations, as well as our ability to pay dividends and to engage in various capital management strategies. Returns on average tangible assets and average tangible stockholders’ equity are among the profitability measures considered by current and prospective investors, both independent of, and in comparison with, our peers. We calculate average tangible stockholders’ equity by subtracting from average stockholders’ equity the sum of our average goodwill and calculate average tangible assets by subtracting the same sum from our average assets. Average tangible stockholders’ equity, average tangible assets, and the related non-GAAP profitability measures should not be considered in isolation or as a substitute for average stockholders’ equity, average assets, or any other profitability or capital measure calculated in accordance with GAAP. Moreover, the manner in which we calculate these non-GAAP measures may differ from that of other companies reporting non-GAAP measures with similar names. The following table presents reconciliations of our average common stockholders’ equity and average tangible common stockholders’ equity, our average assets and average tangible assets, and the related GAAP and non-GAAP profitability measures at or for the three months ended March 31, 2021: (1) To calculate return on average assets for a period, we divide net income generated during that period by average assets recorded during that period. To calculate return on average tangible assets for a period, we divide net income by average tangible assets recorded during that period.   (2) To calculate return on average common stockholders’ equity for a period, we divide net income available to common shareholders generated during that period by average common stockholders’ equity recorded during that period. To calculate return on average tangible common stockholders’ equity for a period, we divide net income available to common shareholders generated during that period by average tangible common stockholders’ equity recorded during that period.
