BankUnited Financial Corporation (referred to on a consolidated basis as the “Company,” “BankUnited,” “we”, “our” or “us”) is unable to file its Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2009 (the “Second Quarter 2009 Form 10-Q”) by the filing deadline of May 11, 2009. This notice contains unaudited information about our results that is subject to change in our Annual Report on Form 10-K for the fiscal year ended September 30, 2008 (the “2008 Form 10-K”), Quarterly Report on Form 10-Q for the fiscal quarter ended December 31, 2008 (the “First Quarter 2009 Form 10-Q”), and Second Quarter 2009 Form 10-Q when filed with the Securities and Exchange Commission (the “SEC”).

We have included selected financial data in this document so that the reader may better understand our current financial condition. This financial data is subject to change, as noted above. The financial data as of and for the period ended March 31, 2009, including the valuation of the investment securities and mortgage-backed securities portfolios and the evaluation of other-than- temporary impairment, is preliminary. In addition, the financial data has been prepared based on the assumption that the Company will continue as a going concern. If the same information were to be prepared and presented on a liquidation basis, the results might be materially different.

Reason for Non-Completion of the Financial Results for March 31, 2009 Quarter

We are not able to file a timely Second Quarter 2009 Form 10-Q because we have not completed the preparation of our financial results for either the fiscal year ended September 30, 2008 (the “fiscal 2008”) or the fiscal quarters ended March 31, 2009 and December 31, 2008. This delay results from the continuing adverse market conditions, the complexity of accounting and disclosure issues, which increased the need for additional review and analysis of our business including, without limitation, regulatory issues, liquidity and capital and the material weaknesses in internal control over financial reporting discussed below. As we have previously notified the NASDAQ, we are working diligently to try to complete the filing of our 2008 Form 10-K, First Quarter 2009 Form 10-Q and Second Quarter 2009 Form 10-Q by June 15, 2009. However, no assurances can be given concerning our ability to file by June 15, 2009. If we do not file by June 15, 2009, we intend to request additional time from NASDAQ to make the required filings, although there is no assurance that they will grant us such additional time.

Regulatory and Enforcement Actions

As disclosed previously, since July 2008, the Company and BankUnited, FSB (the “Bank”), our wholly-owned subsidiary, have entered into various agreements with the Office of Thrift Supervision (the “OTS”) that have progressively increased our regulatory monitoring and reporting requirements and added significant restrictions on our operations.

Most recently, on April 14, 2009, the Board of Directors of the Bank entered into a Stipulation and Consent to Prompt Corrective Action Directive (the “PCA Agreements”) with the OTS. The PCA Agreements reiterated several mandatory operating restrictions of previous agreements, including the Cease and Desist Orders entered into with the OTS on September 19, 2008.

2

The PCA Agreements direct the Bank to be capitalized by a merger with or an acquisition by another financial institution or another entity, or through the sale of all or substantially all of the Bank’s assets and liabilities to another financial institution or another entity, within twenty days of the issuance of the PCA Agreements, pursuant to a written definitive agreement that the Bank was required to execute within fifteen days of the effective date of the PCA Agreements, unless such timeframes were extended in writing by the OTS. The PCA Agreements further required the Bank to achieve and maintain, at a minimum, the following ratios: (i) Total Risk Based Capital Ratio of 8%; (ii) Tier I Core Risk Based Capital Ratio of 4%; and (iii) Leverage Ratio of 4% within twenty days of the effective date of the PCA Agreements. Based on our March 31, 2009 reported capital levels, we would need to raise approximately $1.0 billion to meet the Total Risk Based Capital Ratio of 8%, approximately $706 million to meet the Tier I Core Risk Based Capital Ratio of 4% and approximately $937 million to meet the Leverage Ratio of 4%. The twenty-day period to raise capital and achieve the mandatory minimum capital requirements under the PCA Agreements expired on May 4, 2009 without compliance by the Bank. As a result of the foregoing circumstances, the Bank is subject to regulatory enforcement actions, including the Federal Deposit Insurance Corporation (the “FDIC”) receivership. This, as well as other matters discussed herein, raise substantial doubt about the Company’s ability to continue as a going concern.

Efforts to Raise Capital at the Holding Company

We have been actively trying to raise capital at the holding company level for over a year. These efforts have required substantial time, resources and energy from our senior management, who has persistently sought to identify investors and structure a feasible transaction. Although management continues to seek capital at the holding company level, our efforts at this time primarily relate to a direct recapitalization of the Bank. No assurance can be given that we will be able to raise capital at either the Bank or the holding company level. In addition, a recapitalization of the Bank without a simultaneous recapitalization of the holding company would reduce or eliminate the Company’s ownership in the Bank, thus raising substantial doubt about the Company’s ability to continue as a going concern.

Liquidity and Capital Resources

At May 7, 2009, the Bank had total cash and cash equivalents of $1.3 billion compared to $1.2 billion and $513 million at September 30, 2008 and 2007, respectively. The increase from September 30, 2007 was primarily driven by an increase in retail deposit balances and payments received on the Bank’s loans and investment securities. Management elected to increase cash and cash equivalents in response to market disturbances that adversely affected the liquidity position at other financial institutions.

Since November 2008 the Bank has had no available borrowing capacity with the Federal Home Loan Bank of Atlanta (“FHLB”). As a consequence, we have been repaying the FHLB borrowings as they mature. Similarly, the Bank has had no available borrowing capacity from brokered deposits since July 2008, which we have also been paying as they mature. Our primary funding sources are principal and interest payments from investments and loan portfolios, retail deposit growth and cash reserves. As of March 31, 2009, cash and cash equivalents were $1.5 billion. Repayment of FHLB advances of $145 million and brokered deposits of $112 million at their scheduled maturity dates subsequent to March 31, 2009, resulted in a net decline of cash and cash equivalents to $1.3 billion as of May 7, 2009. We have $395 million of FHLB advances scheduled to mature, and an additional $655 million of FHLB advances are scheduled to mature through the fiscal year ending September 30, 2009. As of May 7, 2009 we had brokered deposits of approximately $182 million maturing through the fiscal year ending September 30, 2009. A continued decline in our financial condition and additional market disturbances could create additional concern among depositors, making retail deposits more costly and difficult to attract and maintain. Nevertheless, we anticipate seeking to maintain and increase our retail deposit levels for liquidity purposes.

In addition to the Bank’s liquidity, management also monitors the liquidity at the holding company. As of May 7, 2009, we had an estimated $19 million of liquid assets available at the holding company. This amount should allow us to meet our obligations at least through the end of the fiscal year ended September 30, 2009 (the “fiscal 2009”) assuming the continued deferrals of our debt service obligations on the trust preferred securities. The Company has estimated its debt service obligations as of March 31, 2009 to be approximately $30 million per year at the holding company level for interest and debt payments on our Convertible Senior Notes, HiMEDS Units senior notes, senior debentures and trust preferred securities. As permitted by the terms of our trust preferred

3

securities, during the fourth fiscal quarter in 2008 (the quarter ended September 30, 2008), we announced that we had elected to defer approximately $13.6 million of the annual debt service obligation on the trust preferred securities. Pursuant to the indentures for the trust preferred securities, we are permitted to defer interest payments for twenty consecutive quarters. As of the date of the filing of this Form 12b-25, we have deferred interest payments for three consecutive quarters. However, we cannot defer annual payments of approximately $16.8 million of combined interest obligations on our Convertible Senior Notes, HiMEDS Units senior notes, and senior debentures, of which $8.4 million is required to be paid between April 1, 2009 and September 30, 2009. Additionally, the holding company incurs non-fixed cash charges for general and administrative matters of approximately $3.6 million per quarter. The PCA Agreements prohibit the Bank from making dividend payments to the holding company and the holding company has few other sources of income. Therefore, no assurances can be given that the Company will be able to make the required payments on the debt after the available liquid assets at the holding company level are depleted. Therefore, there is substantial doubt about our ability to continue as a going concern.

Management’s Assessment of Disclosure Controls and Procedures

As of the filing of this document, we have identified two material weaknesses in our internal control over financial reporting. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. We reported in our previous filings that, based on our assessment thus far and as a result of an insufficient complement of personnel with a level of accounting knowledge, experience and training in the application of generally accepted accounting principles commensurate with our financial reporting requirement, we expect to report at least the following material weaknesses as of September 30, 2008: our controls and procedures did not ensure the systematic and accurate execution of account level analyses related to the residential loan portfolio, including the allowance for loan losses and the identification of troubled debt restructuring, or the accurate preparation of our cash flow statements. We continue to evaluate the effect of subsequent events and consequent adjusting accounting entries on our internal control over financial reporting as of September 30, 2008 and upon conclusion of that evaluation we may have additional material weaknesses to report including, but not limited to, controls over the process of determining the fair value of residential real estate owned properties and investment securities.

Second Fiscal Quarter 2009 Results

We expect that our results for fiscal quarter ended March 31, 2009 (the “Second Quarter 2009”) will be significantly different from our results for the similar quarter in fiscal year 2008. We expect to report a loss of $443.1 million or $12.55 per share for the

4

second quarter 2009 compared to a loss of $65.8 million or $1.88 per share for the quarter ended March 31, 2008. For the six months ended March 31, 2009, we expect to report a loss of approximately $920.6 million, or $26.08 per share compared to a loss of $91.3 million, or $2.61 per share for the same period in 2008. The increase in loss is primarily a result of our continuing recognition of significant provisions for loan losses related to our payment option adjustable rate mortgage portfolio, lower net interest income due to higher nonperforming assets, additional cost of maintaining excess cash for liquidity purposes, other-than-temporary impairments, the write-off of goodwill and higher losses and carrying costs associated with repossessed real estate. As of March 31, 2009, the Company maintains reserves of approximately $1.0 billion for losses on its loan portfolio. All of the estimates are unaudited and subject to change when we file our periodic reports with the SEC.

Additional financial results as of and for the six months ended March 31, 2009 are presented below under Selected Financial Data.
