BASIS OF PRESENTATION	NOTE 1: BASIS OF PRESENTATION The consolidated financial statements include First Foundation Inc. (“FFI”) and its wholly owned subsidiaries: First Foundation Advisors (“FFA”) and First Foundation Bank (“FFB” or the “Bank”) and the wholly owned subsidiaries of FFB, First Foundation Insurance Services (“FFIS”), Blue Moon Management, LLC, and First Foundation Public Finance (“FFPF”) (collectively referred to as the “Company”). FFI also has two inactive wholly owned subsidiaries, First Foundation Consulting (“FFC”) and First Foundation Advisors, LLC (“FFA LLC”). All intercompany balances and transactions have been eliminated in consolidation. The results of operations reflect any interim adjustments, all of which are of a normal recurring nature and which, in the opinion of management, are necessary for a fair presentation of the results for the interim period presented. The results for the 2021 interim periods are not necessarily indicative of the results expected for the full year. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates. The accompanying unaudited consolidated financial statements include all information and footnotes required for interim financial statement presentation. These financial statements assume that readers have read the most recent Annual Report on Form 10-K which contains the latest available audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2020. Certain reclassifications have been made to the prior year consolidated financial statements to conform to the 2021 presentation.

FAIR VALUE MEASUREMENTS	Mar. 31, 2021
FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	NOTE 2: FAIR VALUE MEASUREMENTS Assets Measured at Fair Value on a Recurring Basis Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Current accounting guidance establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. Securities available for sale and investments in equity securities are measured at fair value on a recurring basis depending upon whether the inputs are Level 1, 2 or 3 as described above. The following tables show the recorded amounts of assets and liabilities measured at fair value on a recurring basis as of: Fair Value Measurement Level (dollars in thousands) Total Level 1 Level 2 Level 3 March 31, 2021: Investment securities available for sale: Agency mortgage-backed securities $ 673,164 $ — $ 673,164 $ — Beneficial interest – FHLMC securitizations 17,893 — — 17,893 Corporate bonds 56,554 — 56,554 — Other 1,608 501 1,107 — Investment in equity securities 434 434 — — Total assets at fair value on a recurring basis $ 749,653 $ 935 $ 730,825 $ 17,893 December 31, 2020: Investment securities available for sale: Agency mortgage-backed securities $ 723,995 $ — $ 723,995 $ — Beneficial interest – FHLMC securitizations 23,463 — — 23,463 Corporate bonds 58,358 — 58,358 — Other 1,610 503 1,107 — Investment in equity securities 338 338 — — Total assets at fair value on a recurring basis $ 807,764 $ 841 $ 783,460 $ 23,463 The decrease in Level 3 assets from December 31, 2020 was due to securitization paydowns and to $1.6 million in provisions for credit losses in the first three months of 2021. Assets Measured at Fair Value on a Nonrecurring Basis From time to time, we may be required to measure other assets at fair value on a nonrecurring basis. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets. Loans Real Estate Owned Mortgage Servicing Rights. Fair Value of Financial Instruments FASB ASC 825-10, “Disclosures about Fair Value of Financial Instruments” requires disclosure of the fair value information about financial instruments, whether or not recognized in the balance sheet, for which it is practicable to estimate such value. The methodologies for estimating the fair value of financial assets and financial liabilities measured at fair value on a recurring and non-recurring basis are discussed above. The estimated fair value amounts have been determined by management using available market information and appropriate valuation methodologies and are based on the exit price notion set forth by ASU 2016-01. In cases where quoted market prices are not available, fair values are based on estimates using present value or other market value techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The aggregate fair value amounts presented below do not represent the underlying value of the Company. Fair value estimates are made at a discrete point in time based on relevant market information and other information about the financial instruments. Because no active market exists for a significant portion of our financial instruments, fair value estimates are based in large part on judgments we make primarily regarding current economic conditions, risk characteristics of various financial instruments, prepayment rates, and future expected loss experience. These estimates are subjective in nature and invariably involve some inherent uncertainties. Additionally, unexpected changes in events or circumstances can occur that could require us to make changes to our assumptions and which, in turn, could significantly affect and require us to make changes to our previous estimates of fair value. In addition, the fair value estimates are based on existing on and off-balance sheet financial instruments without attempting to estimate the value of existing and anticipated future customer relationships and the value of assets and liabilities that are not considered financial instruments, such as premises and equipment and other real estate owned. The following methods and assumptions were used to estimate the fair value of financial instruments: Cash and Cash Equivalents Interest-Bearing Deposits with Financial Institutions Investment Securities Available for Sale Federal Home Loan Bank Stock. Loans Held For Sale. Loans Held for Investment Deposits Borrowings The carrying amounts and estimated fair values of financial instruments are as follows as of: Carrying Fair Value Measurement Level (dollars in thousands) Value 1 2 3 Total March 31, 2021: Assets: Cash and cash equivalents $ 468,026 $ 468,026 $ — $ — $ 468,026 Securities AFS, net 749,219 501 730,825 17,893 749,219 Loans held for sale 513,054 — 518,368 — 518,368 Loans, net 5,094,026 — — 5,146,920 5,146,920 Investment in FHLB stock 17,250 — 17,250 — 17,250 Investment in equity securities 434 434 — — 434 Liabilities: Deposits $ 6,245,821 $ 5,480,156 $ 765,666 $ — $ 6,245,822 Borrowings 12,000 — 5,000 7,000 12,000 December 31, 2020: Assets: Cash and cash equivalents $ 629,707 $ 629,707 $ — $ — $ 629,707 Securities AFS, net 807,426 503 783,460 23,463 807,426 Loans held for sale 505,404 — 510,638 — 510,638 Loans, net 4,779,599 — — 4,829,258 4,829,258 Investment in FHLB stock 17,250 — 17,250 — 17,250 Investment in equity securities 338 338 — — 338 Liabilities: Deposits $ 5,913,433 $ 4,934,537 $ 978,897 $ — $ 5,913,434 Borrowings 269,000 — 255,000 14,000 269,000

As of March 31, 2021, $191.8 million of agency mortgage-backed securities are pledged as collateral as support for the Bank’s obligations under loan sales and securitization agreements entered into from 2018 through 2020. The table below indicates, as of March 31, 2021, the gross unrealized losses and fair values of our investments, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position.

Unrealized losses in agency mortgage backed securities, beneficial interests in FHLMC securitizations, and other securities have not been recognized into income because the issuer bonds are of high credit quality, management does not intend to sell, it is not more likely than not that management would be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in discount rates and assumptions regarding future interest rates. The fair value is expected to recover as the bonds approach maturity.

At December 31, 2020, our borrowings consisted of $255 million of overnight FHLB advances at the Bank and $14 million of borrowings under a holding company line of credit. The zero interest advance outstanding at March 31, 2021 matures in April 2021. At March 31, 2021, the interest rate on the holding company line of credit was 3.74%. FHLB advances are collateralized primarily by loans secured by single family, multifamily, and commercial real estate properties with a carrying value of $3.6 billion as of March 31, 2021. As a matter of practice, the Bank provides substantially all of its qualifying loans as collateral to the FHLB or the Federal Reserve Bank. The Bank’s total borrowing capacity from the FHLB at March 31, 2021 was $2.3 billion. In addition to the $5 million borrowing at March 31, 2021, the Bank had in place $277 million of letters of credit from the FHLB which are used to meet collateral requirements for borrowings from the State of California and local agencies. During 2017, FFI entered into a loan agreement with an unaffiliated lender that provides for a revolving line of credit for up to $40 million. The loan agreement matures in five years, with an option to extend the maturity date subject to certain conditions, and bears interest at 90 day LIBOR plus 350 The Bank also has $195 million available borrowing capacity through unsecured fed funds lines, ranging in size from $20 million to $100 million, with five other financial institutions, and a $188 million secured line with the Federal Reserve Bank, secured by single family loans. None of these lines had outstanding borrowings as March 31, 2021.

EARNINGS PER SHARE
EARNINGS PER SHARE	NOTE 9: EARNINGS PER SHARE Basic earnings per share excludes dilution and is computed by dividing net income or loss available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects the potential dilution that could occur if contracts to issue common stock were exercised or converted into common stock that would then share in earnings. The following table sets forth the Company’s unaudited earnings per share calculations for the three months ended March 31: Quarter Ended Quarter Ended March 31, 2021 March 31, 2020 (dollars in thousands, except per share amounts) Basic Diluted Basic Diluted Net income $ 22,355 $ 22,355 $ 13,211 $ 13,211 Basic common shares outstanding 44,707,718 44,707,718 44,669,661 44,669,661 Effect of options, restricted stock and contingent shares issuable 304,487 283,008 Diluted common shares outstanding 45,012,205 44,952,669 Earnings per share $ 0.50 $ 0.50 $ 0.30 $ 0.29 Based on a weighted average basis, restricted stock units to purchase 102,708 and 118,750 shares of common stock were excluded for the three months ended March 31, 2021 and 2020, respectively, because their effect would have been anti-dilutive.

(“FFI”) and its wholly owned subsidiaries: First Foundation Advisors (“FFA”) and First Foundation Bank (“FFB” or the “Bank”) and the wholly owned subsidiaries of FFB, First Foundation Insurance Services (“FFIS”), Blue Moon Management, LLC, and First Foundation Public Finance (“FFPF”) (collectively referred to as the “Company”). FFI also has two inactive wholly owned subsidiaries, First Foundation Consulting (“FFC”) and First Foundation Advisors, LLC (“FFA LLC”). All intercompany balances and transactions have been eliminated in consolidation. The results of operations reflect any interim adjustments, all of which are of a normal recurring nature and which, in the opinion of management, are necessary for a fair presentation of the results for the interim period presented. The results for the 2021 interim periods are not necessarily indicative of the results expected for the full year. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and revenues and expenses for the period. Actual results could differ significantly from those estimates. The accompanying unaudited consolidated financial statements include all information and footnotes required for interim financial statement presentation. These financial statements assume that readers have read the most recent Annual Report on Form 10-K which contains the latest available audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2020. Certain reclassifications have been made to the prior year consolidated financial statements to conform to the 2021 presentation.
