BASIS OF PRESENTATION
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 and First Foundation Advisors, 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 2022 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, 2021. Certain reclassifications have been made to the prior year consolidated financial statements to conform to the 2022 presentation. New Accounting Pronouncements In March 2022, the Financial Accounting Standards Board (“FASB”) issued ASU 2022-02, “ Financial Instruments – Credit Losses (Topic 326), Troubled Debt Restructurings (“TDRs”) and Vintage Disclosures” Subtopic 310-40, Receivables – Troubled Debt Restructurings by Creditors Financial Instruments – Credit Losses on Financial Instruments In March 2020, the FASB issued ASU 2020-04, “ Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting”

ACQUISITIONS
ACQUISITIONS	​ NOTE 2: ACQUISITIONS On December 17, 2021, the Company completed the acquisition of TGR Financial, Inc. (“TGRF”) and its wholly owned subsidiary, First Florida Integrity Bank, through a merger of TGRF with and into FFI followed immediately by the merger of First Florida Integrity Bank with and into FFB, in exchange for 11,352,232 shares of FFI common stock with a fair value of $24.93 per share. The acquisition was accounted for under the purchase method of accounting. The acquired assets, assumed liabilities and identifiable intangible assets are recorded at their respective acquisition date fair values. Goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining TGRF into FFI. None of the goodwill recognized is expected to be deductible for income tax purposes. The following table represents the assets acquired and liabilities assumed of TGRF as of December 17, 2021 and the fair value adjustments and amounts recorded by the Company in 2021 under the acquisition method of accounting: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ TGRF Book Fair Value ​ ​ (dollars in thousands) ​ Value ​ Adjustments ​ Fair Value Assets Acquired: ​ ​ ​ Cash and cash equivalents ​ $ 1,145,335 ​ $ 5 ​ $ 1,145,340 Securities AFS ​ 147,739 ​ 109 ​ 147,848 Securities held-to-maturity ​ ​ 71,790 ​ ​ 2,115 ​ ​ 73,905 Loans, net of deferred fees ​ 1,045,193 ​ (5,387) ​ 1,039,806 Investment in FHLB stock ​ 4,510 ​ — ​ 4,510 Premises and equipment, net ​ 34,199 ​ (4,180) ​ 30,019 Goodwill and intangibles ​ 181 ​ 129,850 ​ 130,031 Bank owned life insurance ​ 46,163 ​ — ​ 46,163 Deferred taxes ​ 3,414 ​ 738 ​ 4,152 Other assets ​ 13,562 ​ (298) ​ 13,264 Total assets acquired ​ $ 2,512,086 ​ $ 122,952 ​ $ 2,635,038 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Liabilities Assumed: ​ ​ ​ Deposits ​ $ 2,170,676 ​ $ 313 ​ $ 2,170,989 Borrowings ​ 177,114 ​ 1,929 ​ 179,043 Accounts payable and other liabilities ​ 7,386 ​ 182 ​ 7,568 Total liabilities assumed ​ 2,355,176 ​ 2,424 ​ 2,357,600 Excess of assets acquired over liabilities assumed ​ 156,910 ​ 120,528 ​ 277,438 Total ​ $ 2,512,086 ​ $ 122,952 ​ $ 2,635,038 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consideration: ​ ​ ​ Stock issued ​ ​ ​ $ 283,011 Cash paid ​ ​ ​ ​ ​ ​ ​ ​ 10 Total consideration (1) ​ ​ ​ ​ ​ ​ ​ $ 283,021 ​ (1) The difference between total consideration and the excess of assets acquired over liabilities assumed relates to the recognition of a credit loss reserve for non-PCD loans of $5.6 million, which is recognized as an expense in the consolidated income statement on the acquisition date. In many cases, the fair values of assets acquired and liabilities assumed were determined by estimating the cash flows expected to result from those assets and liabilities and discounting them at appropriate market rates. The most significant category of assets for which this procedure was used was that of acquired loans. The excess of expected cash flows above the fair value (Level 3 inputs) of the majority of loans will be accreted to interest income over the remaining lives of the loans in accordance with Accounting Standards Codification (“ASC”) 310-20. The fair values are estimates and are subject to adjustment for up to one year after the merger date. Certain loans, for which specific credit-related deterioration since origination was identified, are recorded at fair value reflecting the present value of the amounts expected to be collected. Income recognition on these purchased credit deteriorated (“PCD”) loans is based on a reasonable expectation about the timing and amount of cash flows to be collected. Acquired loans deemed impaired and considered collateral dependent, with the timing of the sale of loan collateral indeterminate, remain on nonaccrual status and have no accretable yield. All PCD loans were classified as accruing loans as of and subsequent to the acquisition date. In accordance with generally accepted accounting principles there was no carryover of the allowance for credit losses that had been previously recorded by TGRF. The Company recorded a deferred income tax asset of $4.2 million related to the acquisition of TGRF, including operating loss carry-forwards of $0.1 million that are subject to limitation under Section 382 of the Internal Revenue Code. The fair value of savings and transaction deposit accounts acquired from TGRF were assumed to approximate their carrying value as these accounts have no stated maturity and are payable on demand. Certificates of deposit accounts were valued by comparing the contractual cost of the portfolio to an identical portfolio bearing current market rates (Level 2 inputs). The portfolio was segregated into pools based on remaining maturity. For each pool, the projected cash flows from maturing certificates were then calculated based on contractual rates and prevailing market rates. The valuation adjustment for each pool is equal to the present value of the difference of these two cash flows, discounted at the assumed market rate for a certificate with a corresponding maturity. This valuation adjustment will be accreted to reduce interest expense over the remaining maturities of the respective pools. The Company also recorded a core deposit intangible, which represents the value of the deposit relationships acquired from TGRF, of $3.3 million. The core deposit intangible will be amortized over a period of 10 years. Pro Forma Information (unaudited) The following table presents unaudited pro forma information for the nine months ended September 30, 2021, as if the acquisition of TGRF had occurred on January 1, 2021, after giving effect to certain adjustments. The unaudited pro forma information for this period includes adjustments for interest income on loans acquired, amortization of intangibles arising from the transaction, adjustments for interest expense on deposits acquired, and the related income tax effects of all these items and the income tax costs or benefits derived from the income or loss before taxes of TGRF. The net effect of these pro forma adjustments was an increase of $0.5 million and $1.5 million in net income for the three and nine months ended September 30, 2021, respectively. The unaudited pro forma financial information is not necessarily indicative of the results of operations that would have occurred had the transaction been effected on the assumed dates. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Nine Months Ended (dollars in thousands) ​ September 30, 2021 September 30, 2021 Net interest income ​ $ 73,154 ​ $ 213,840 Provision for credit losses ​ ​ 5,170 ​ 16,742 Noninterest income ​ ​ 32,171 ​ 60,645 Noninterest expenses ​ ​ 61,263 ​ 178,582 Income before taxes ​ ​ 38,892 ​ 79,161 Taxes on income ​ ​ 10,614 ​ 21,345 Net income ​ $ 28,278 ​ $ 57,816 ​ ​ ​ ​ ​ ​ ​ Net income per share: ​ ​ Basic ​ $ 0.51 ​ $ 1.03 Diluted ​ $ 0.50 ​ $ 1.03 ​

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS	NOTE 3: 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.

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 December 31, 2021, respectively. There were $0.7 million in specific reserves related to these loans at September 30, 2022 and no specific reserves at December 31, 2021. Real Estate Owned Mortgage Servicing Rights. Fair Value of Financial Instruments FASB ASC 825-10, “ Disclosures about Fair Value of Financial Instruments 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 Investment Securities Available for Sale classified as Level 3 and reliance is placed upon internally developed models, and management judgment and evaluation for valuation. Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets and money market funds. Level 2 securities include mortgage-backed securities issued by government sponsored entities, municipal bonds and corporate debt securities. Securities classified as Level 3 include beneficial interests in FHLMC securitizations and investment in equity securities. Significant assumptions in the valuation of these Level 3 securities as of September 30, 2022 and December 31, 2021 included prepayment rates ranging from 35% to 45% and discount rates ranging from 8.07% to 10.00%.

The Company reassessed classification of certain securities AFS and effective January 1, 2022, the Company transferred $917 million in securities AFS to securities HTM. The securities were transferred at their amortized cost basis, net of any remaining unrealized gain or loss reported in accumulated other comprehensive income. The related unrealized loss of $0.6 million included in other comprehensive income remained in other comprehensive income to be amortized, with an offsetting entry to interest income as a yield adjustment through earnings over the remaining term of the securities. Subsequent to transfer, the ACL on these securities was evaluated under the accounting policy for securities HTM. We monitor the credit quality of these securities by evaluating various quantitative attributes. The credit quality indicators the Company monitors include, but are not limited to, credit ratings of individual securities and the credit rating of government sponsored enterprises that guarantee the securities. Credit ratings express opinions about the credit quality of a security. Securities rated investment grade, that is, those with ratings similar to BBB-/Baa3 or above, as defined by NRSROs, are generally considered by the rating agencies and market participants to be investment grade. As of September 30, 2022, all the Company’s securities were either investment grade or were issued by a U.S. government agency or a U.S. government sponsored enterprise with an investment grade rating. The tables below indicate, as of September 30, 2022, and December 31, 2021, the gross unrealized losses and fair values of our investments AFS, aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Securities with Unrealized Loss at September 30, 2022 ​ ​ Less than 12 months ​ 12 months or more ​ Total ​ ​ Fair ​ Unrealized ​ Fair ​ Unrealized ​ Fair ​ Unrealized (dollars in thousands) Value Loss Value Loss Value Loss Collateralized mortgage obligations ​ $ 9,275 ​ $ (1,225) ​ $ — ​ $ — ​ $ 9,275 ​ $ (1,225) Agency mortgage-backed securities ​ ​ 8,164 ​ ​ (634) ​ ​ — ​ ​ — ​ ​ 8,164 ​ ​ (634) Municipal bonds ​ ​ 45,200 ​ ​ (5,197) ​ ​ — ​ ​ — ​ ​ 45,200 ​ ​ (5,197) SBA securities ​ ​ 17,353 ​ ​ (111) ​ ​ — ​ ​ — ​ ​ 17,353 ​ ​ (111) Beneficial interests in FHLMC securitization ​ ​ 4,240 ​ ​ (7) ​ ​ — ​ ​ — ​ ​ 4,240 ​ ​ (7) Corporate bonds ​ ​ 117,180 ​ ​ (7,899) ​ ​ 17,916 ​ ​ (2,084) ​ ​ 135,096 ​ ​ (9,983) U.S. Treasury ​ ​ 373 ​ ​ (26) ​ ​ 444 ​ ​ (55) ​ ​ 817 ​ ​ (81) Total temporarily impaired securities ​ $ 201,785 ​ $ (15,099) ​ $ 18,360 ​ $ (2,139) ​ $ 220,145 ​ $ (17,238) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Securities with Unrealized Loss at December 31, 2021 ​ ​ Less than 12 months ​ 12 months or more ​ Total ​ ​ Fair ​ Unrealized ​ Fair ​ Unrealized ​ Fair ​ Unrealized (dollars in thousands) Value Loss Value Loss Value Loss Collateralized mortgage obligations $ 12,971 $ (37) $ — $ — $ 12,971 $ (37) Agency mortgage-backed securities ​ ​ 434,973 ​ ​ (5,051) ​ ​ 36,136 ​ ​ (1,069) ​ ​ 471,109 ​ ​ (6,120) Municipal bonds ​ ​ 2,025 ​ ​ — ​ ​ — ​ ​ — ​ ​ 2,025 ​ ​ — SBA securities ​ ​ 501 ​ ​ — ​ ​ — ​ ​ — ​ ​ 501 ​ ​ — Corporate bonds ​ ​ 47,880 ​ ​ (92) ​ ​ — ​ ​ — ​ ​ 47,880 ​ ​ (92) U.S. Treasury ​ 491 ​ (9) ​ — ​ — ​ 491 ​ (9) Total temporarily impaired securities ​ $ 498,841 ​ $ (5,189) ​ $ 36,136 ​ $ (1,069) ​ $ 534,977 ​ $ (6,258) ​ ​ 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. The following is a roll forward of our allowance for credit losses related to securities for the following periods: ​ ​ ​ ​ ​ (dollars in thousands) ​ Total ​ ​ ​ ​ Three Months Ended September 30, 2022: ​ ​ ​ Beginning balance $ 11,226 Provision for credit losses ​ 293 Balance: September 30, 2022 $ 11,519 ​ ​ ​ ​ Nine Months Ended September 30, 2022: ​ ​ ​ Beginning balance $ 10,399 Provision for credit losses ​ 1,120 Balance: September 30, 2022 $ 11,519 ​ ​ ​ ​ Year Ended December 31, 2021: ​ ​ ​ Beginning balance $ 7,245 Provision for credit losses ​ 3,154 Balance: December 31, 2021 $ 10,399 ​ Due to a change in expected cash flows of interest only strip securities, $0.3 million and $1.1 million in provisions were taken in the three and nine months ended September 30, 2022, respectively, and $1.0 million and $2.9 million in provisions were taken in the three and nine months ended September 30, 2021, respectively. The allowances were included as a charge in provision for credit losses on the consolidated income statement. The ACL on investment securities is determined for both held-to-maturity and available-for-sale classifications of the investment portfolio in accordance with ASC 326, and is evaluated on a quarterly basis. The ACL for held-to-maturity investment securities is determined on a collective basis, based on shared risk characteristics, and is determined at the individual security level when the Company deems a security to no longer possess shared risk characteristics. Under ASC 326-20, for investment securities where the Company has reason to believe the credit loss exposure is remote, such as those guaranteed by the U.S. government or government sponsored entities, a zero loss expectation is applied and a company is not required to estimate and recognize an ACL. For securities AFS in an unrealized loss position, the Company first evaluates whether it intends to sell, or whether it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of these criteria regarding intent or requirement to sell is met, the security amortized cost basis is written down to fair value through income. If neither criteria is met, the Company is required to assess whether the decline in fair value has resulted from credit losses or noncredit-related factors. In determining whether a security’s decline in fair value is credit related, the Company considers a number of factors including, but not limited to: (i) the extent to which the fair value of the investment is less than its amortized cost; (ii) the financial condition and near-term prospects of the issuer; (iii) downgrades in credit ratings; (iv) payment structure of the security, and (v) the ability of the issuer of the security to make scheduled principal and interest payments. If, after considering these factors, the present value of expected cash flows to be collected is less than the amortized cost basis, a credit loss exists, and an allowance for credit loss is recorded through income as a component of provision for credit loss expense. If the assessment indicates that a credit loss does not exist, the Company records the decline in fair value through other comprehensive income, net of related income tax effects. The Company has made the election to exclude accrued interest receivable on securities from the estimate of credit losses and report accrued interest separately on the consolidated balance sheets. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of a security is confirmed or when either of the criteria regarding intent or requirement to sell is met.

BORROWINGS
BORROWINGS	NOTE 9: BORROWINGS At September 30, 2022, our borrowings consisted of $1.1 billion in overnight FHLB advances at the Bank, $174 million in subordinated notes at the holding company, and $179 million of repurchase agreements at the Bank. At December 31, 2021, our borrowings consisted of $26 million in subordinated notes at FFI, $166 million of repurchase agreements at the Bank, and $18.5 million of borrowings under a holding company line of credit. The FHLB overnight advances were paid in full in the early part of October 2022 and bore an interest rate of 3.22%. As of September 30, 2022, $150 million of the subordinated notes are fixed-to-floating rate notes that mature in February 2032. The notes will initially bear a rate of 3.50% per annum, payable semi-annually in arrears on February 1 and August 1 of each year, commencing on August 1, 2022, until February 1, 2027. From and including February 1, 2027 to, but excluding February 1, 2032, or the date of earlier redemption, the notes will bear interest at a floating rate per annum equal to the Benchmark rate (which is expected to be Three-Month Term Secured Overnight Financing Rate, or “SOFR”), each as defined in and subject to the provisions of the indenture under which the notes were issued, plus 204 basis points (2.04%), payable quarterly in arrears on February 1, May 1, August 1, and November 1 of each year, commencing on May 1, 2027. $24 million of the subordinated notes mature in June 2030 and bear a fixed interest rate of 6.0%, until June 30, 2025, at which time they will convert to a floating rate based on three month SOFR, plus 590 basis points (5.90%), until maturity. As a matter of practice, the Bank provides substantially all of its qualifying loans as collateral to the FHLB or the Federal Reserve Bank. FHLB advances are collateralized primarily by loans secured by single family, multifamily, and commercial real estate properties with a carrying value of $5.0 billion as of September 30, 2022. The Bank’s total remaining borrowing capacity from the FHLB at September 30, 2022 was $1.8 billion. The Bank had in place $315 million of letters of credit from the FHLB, as of September 30, 2022 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 $20 million. The loan agreement matures in February 2023, with an option to extend the maturity date subject to certain conditions, and bears interest at Prime rate, plus 50 basis points (0.50%). FFI’s obligations under the loan agreement are secured by, among other things, a pledge of all of its equity in FFB. We are required to meet certain financial covenants during the term of the loan, including minimum capital levels and limits on classified assets. As of September 30, 2022 and December 31, 2021, FFI was in compliance with the covenants on this loan agreement. The Bank also has $245 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 $345 million secured line with the Federal Reserve Bank, secured by single family loans. None of these lines had outstanding borrowings as September 30, 2022. Combined, the Bank’s unused lines of credit as of September 30, 2022, and December 31, 2021, were $2.4 billion and $3.1 billion, respectively. The average balance of overnight borrowings during the first nine months of 2022 was $165.1 million, as compared to $1.0 million during all of 2021.

EARNINGS PER SHARE
EARNINGS PER SHARE	NOTE 10: 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.
