NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(in thousands of dollars, except per share data)

NOTE 1: Nature of operations and basis of presentation

The consolidated financial statements include the accounts of CenterState Bank Corporation (the “Parent Company,” “Company” or “CSFL”), and its wholly owned subsidiary bank, CenterState Bank, N.A. (“CenterState” or “Bank”), and non-bank subsidiaries, R4ALL, Inc. and CSFL Insurance Corp. The Company operates as one of the largest community bank franchises headquartered in the state of Florida. The Bank provides traditional retail, commercial, mortgage, wealth management and SBA services throughout its Florida, Georgia and Alabama branch network and customer relationships in neighboring states.

The Bank, headquartered in Winter Haven, Florida, also operates a correspondent banking and capital markets division, of which the majority of its bond salesmen, traders and operational personnel are primarily housed in facilities located in Birmingham, Alabama and Atlanta, Georgia. This division’s primary revenue generating activities are related to its capital markets division, which includes commissions earned on fixed income security sales, fees from hedging services, loan brokerage fees and consulting fees for services related to these activities; and its correspondent banking division, which includes spread income earned on correspondent bank deposits (i.e. federal funds purchased) and correspondent bank checking account deposits and fees from safe-keeping activities, bond accounting services for correspondents, asset/liability consulting related activities, international wires, and other clearing and corporate checking account services. The customer base includes small to medium size financial institutions primarily located in the Southeastern United States, although clients are located across the United States.

R4ALL, Inc. manages troubled loans purchased from the Bank to their eventual disposition. CSFL Insurance Corp. is a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial statements and with the instructions to Form 10-Q. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. These statements should be read in conjunction with the consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2018. In the Company’s opinion, all adjustments, consisting primarily of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods have been made. The results of operations of the three-month period ended March 31, 2019 are not necessarily indicative of the results expected for the full year.

Some items in the prior period financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior period net income or shareholders’ equity.

(in thousands of dollars, except per share data)

NOTE 2: Common stock outstanding and earnings per share data

The two-class method is used in the calculation of basic and diluted earnings per share. Under the two-class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared (or accumulated) and participation rights in undistributed earnings. There were no anti-dilutive stock options for the three-month periods ending March 31, 2019 and 2018. The following table presents the factors used in the earnings per share computations for the periods indicated.

	Three months ended March 31,
	2019			2018
Basic
Net income available to common shareholders	$	44,643		$	35,636
Less: Earnings allocated to participating securities		(23	)		(29	)
Net income allocated to common shareholders	$	44,620		$	35,607

Weighted average common shares outstanding
including participating securities		95,790,456			83,208,874
Less: Participating securities (1)		(49,600	)		(69,133	)
Average shares		95,740,856			83,139,741
Basic earnings per common share	$	0.47		$	0.43

Diluted
Net income available to common shareholders	$	44,620		$	35,607
Weighted average common shares outstanding for
basic earnings per common share		95,740,856			83,139,741
Add: Dilutive effects of stock based compensation awards		759,884			1,461,183
Average shares and dilutive potential common shares		96,500,740			84,600,924
Diluted earnings per common share	$	0.46		$	0.42

(1)

Participating securities are restricted stock awards whereby the stock certificates have been issued, are included in outstanding shares, receive dividends and can be voted, but have not vested.

NOTE 3: Fair value

Generally accepted accounting principles establish 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. The standard describes three levels of inputs that may be used to measure fair value:

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 a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The fair values of available for sale debt securities are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). The fair values of corporate debt securities are calculated using market indicators such as broker quotes (Level 2).

The fair values of trading securities are determined as follows: (1) for those securities that have traded prior to the date of the consolidated balance sheet but have not settled (date of sale) until after such date, the sales price is used as the fair value; and, (2) for those securities which have not traded as of the date of the consolidated balance sheet, the fair value was determined by broker price indications of similar or same securities.

Effective January 1, 2018, the Company elected to account for mortgage loans held for sale under the fair value option with changes in fair value recognized in current period earnings. These loans are intended for sale and the Company believes that the fair

value is the best indicator of the resolution of these loans (Level 2). In conjunction with the fair value election on loans held for sale, Mortgage banking uses derivative forward sales contracts and interest rate lock commitments on residential mortgage loans. Fair values of these mortgage derivatives are estimated based on changes in market prices for mortgage forward trades and mortgage interest rates (Level 2) and estimated pull through percentages from the date the interest on the loan is locked (Level 3).

The Company has the rights to service a portfolio of Fannie Mae and other government guaranteed loans sold on a servicing retained basis. Mortgage servicing assets are measured at fair value when the loan is sold and subsequently measured at fair value on a recurring basis utilizing Level 2 inputs. Management uses a model operated and maintained by a third party to calculate the present value of future cash flows using the third party's market-based assumptions. The future cash flows for each asset are based on the asset's unique characteristics and the third party's market-based assumptions for prepayment speeds, default and voluntary prepayments. Adjustments to fair value are recorded as a component of Mortgage Banking Revenue in the Consolidated Statements of Income and Comprehensive Income.

The fair value of interest rate swap derivatives is based on valuation models using observable market data as of the measurement date (Level 2). The derivatives are traded in an over-the-counter market where quoted market prices are not always available. Therefore, fair values of derivatives are determined using quantitative models that utilize multiple market inputs. The inputs will vary based on the type of derivative, but could include interest rates, prices and indices to generate continuous yield or pricing curves, prepayment rates, and volatility factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services.

The fair value of impaired loans with specific valuation allowance for loan losses and other real estate owned is based on recent real estate appraisals. For residential real estate impaired loans and other real estate owned, appraised values are based on the comparative sales approach. For commercial and commercial real estate impaired loans, and other real estate owned, appraisers may use either a single valuation approach or a combination of approaches such as comparative sales, cost or the income approach. A significant unobservable input in the income approach is the estimated income capitalization rate for a given piece of collateral. At March 31 2019, the range of capitalization rates utilized to determine the fair value of the underlying collateral ranged from 4% to 12%. Adjustments to appraisals may be made by the appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of a given asset over time. As such, the fair value of impaired loans, other real estate owned and bank property held for sale are considered a Level 3 in the fair value hierarchy.

Impaired loans measured at fair value had a recorded investment of $11,298 with a valuation allowance of $2,355 at March 31, 2019, and a recorded investment of $8,829, with a valuation allowance of $1,463 at December 31, 2018. The Company recorded a provision for loan loss expense of $1,124 and $68 on impaired loans carried at fair value during the three-month periods ending March 31, 2019 and 2018, respectively.

Other real estate owned had a decline in fair value of $108 and $187 during the three-month periods ending March 31, 2019 and 2018, respectively. Changes in fair value were recorded directly to current earnings through non-interest expense.

Bank property held for sale represents certain branch office buildings which the Company has closed and consolidated with other existing branches. The real estate was transferred out of the Bank Premises and Equipment category into bank property held for sale at the lower of amortized cost or fair value less estimated costs to sell. The fair values were based upon appraisals. The Company recognized an impairment charge of $107 and $1,449 during the three-month periods ending March 31, 2019 and 2018, respectively, related to bank properties held for sale.

Fair Value of Financial Instruments:

The methods and assumptions, not previously presented, used to estimate fair value are described as follows:

Cash and Cash Equivalents: The carrying amounts of cash and cash equivalents approximate fair values and are classified as Level 1.

FHLB, FRB and Other Stock: It is not practical to determine the fair value of FHLB, FRB and other stock due to restrictions placed on their transferability.

CenterState Bank Corporation and Subsidiaries

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(in thousands of dollars, except per share data)

Investment securities held to maturity: The fair values of securities held to maturity are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs).

Loans, net: For performing loans, the fair value is determined based on a discounted cash flow analysis (income approach). The discounted cash flow was based on contractual maturity of the loan and market indications of rates, prepayment speeds, defaults and credit risk resulting in Level 3 classification. For non-performing loans, the fair value is determined based on the estimated values of the underlying collateral or individual analysis of receipts (asset approach) resulting in Level 3 classification.

Accrued Interest Receivable: The carrying amount of accrued interest receivable approximates fair value and is classified as Level 2 for accrued interest receivable related to investment securities and Level 3 for accrued interest receivable related to loans.

Deposits: The fair values disclosed for demand deposits (e.g., interest and non-interest checking, savings, and money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) resulting in Level 1 classification. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification.

Short-term Borrowings: The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within ninety days, approximate their fair values resulting in a Level 2 classification.

Corporate Debentures: The fair values of the Company’s corporate debentures are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification.

Accrued Interest Payable: The carrying amount of accrued interest payable approximates fair value resulting in a Level 2 classification.

Off-balance Sheet Instruments: The fair value of off-balance-sheet items is not considered material.

The following table presents the carry amounts and estimated fair values of the Company’s financial instruments:

Obligations of U.S. government sponsored entities and agencies: Obligations of U.S. government-sponsored entities and agencies are mainly comprised of pools of securities issued by the Small Business Administration (“SBA”). Because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at March 31, 2019.

Mortgage-backed securities: At March 31, 2019, 100% of the mortgage-backed securities held by the Company were issued by U.S. government-sponsored entities and agencies, primarily Fannie Mae, Freddie Mac, and Ginnie Mae, institutions which the government has affirmed its commitment to support. Because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and because the Company does not have the intent to sell these mortgage-backed securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at March 31, 2019.

Municipal securities: Unrealized losses on municipal securities have not been recognized into income because the issuers bonds are of high quality, and because management does not intend to sell these investments or more likely than not will not be required to sell these investments before their anticipated recovery. The fair value is expected to recover as the securities approach maturity.

NOTE 6: Loans Held for Sale

Effective January 1, 2018, the Company elected to account for these loans under the fair value option with changes in fair value recognized in current period earnings. At the date of funding of the loan, the funded amount of the loan, the relative derivative asset or liability of the associated interest rate lock commitment, less direct costs, becomes the initial recorded investment in the loan held for sale. Such amount approximates the fair value of the loan. This change was accounted for on a prospective basis. Net gains from changes in estimated fair value of mortgage loans held for sale were $4 at March 31, 2019. The total unpaid principal balance of loans held for sale was $49,470 and $39,318 at March 31, 2019 and December 31, 2018, respectively. No loans held for sale at March 31, 2019 were past due or on nonaccrual.

As loans are closed, they are typically sold at prices specified in the forward contracts. Gains or losses may arise if the yields of the loans delivered vary from those specified in the forward contracts. Derivative mortgage loan commitments, or interest rate locks, are also utilized and relate to the origination of a mortgage that will be held for sale upon funding. The Company uses these derivative financial instruments on its loans held for sale to manage interest rate risk and not for speculative purposes. The net realized gain on sales of loans held for sale of $3,976, the mortgage servicing fee of $93, and the net unrealized gain on mortgage banking derivatives of $557, the change in fair value of $4, mortgage hedge loss of $404, and mortgage servicing asset loss of $33 are the components of Mortgage Banking Revenue as of March 31, 2019. The net realized gain on sales of loans held for sale of $1,574, the net unrealized gain on mortgage banking derivatives of $665, and the change in fair value of $363 are the main components of Mortgage Banking Revenue as of March 31, 2018. The Mortgage Banking Revenue amounts are reported in the Company’s Consolidated Statements of Income and Comprehensive Income. The table below summarizes the notional amounts for interest rate lock commitments, best efforts forward trades and MBS forward trades pertaining to loans held for sale at March 31, 2019 and 2018.

Mortgage banking derivatives used in the ordinary course of business consist of forward sales contracts and interest rate lock commitments on residential mortgage loans. Forward sales contracts represent future commitments to deliver loans at a specified price and by a specified date and are used to manage interest rate risk on loan commitments and mortgage loans held for sale. Rate lock commitments represent commitments to fund loans at a specific rate and by a specified expiration date. These derivatives involve underlying items, such as interest rates, and are designed to mitigate risk. Notional amounts are amounts on which calculations and payments are based, but which do not represent credit exposure, as credit exposure is limited to the amounts required to be received or paid.

Troubled Debt Restructurings:

In certain situations, it is common to restructure or modify the terms of troubled loans (i.e. troubled debt restructure or “TDRs”). In those circumstances, it may be beneficial to restructure the terms of a loan and work with the borrower for the benefit of both parties, versus forcing the property into foreclosure and having to dispose of it in a distressed sale. When the terms of a loan have been modified, usually the monthly payment and/or interest rate is reduced for generally twelve to twenty-four months. The Company has not forgiven any material principal amounts on any loan modifications to date.

TDRs as of March 31, 2019 and December 31, 2018 quantified by loan type classified separately as accrual (performing loans) and non-accrual (non-performing loans) are presented in the tables below.

As of March 31, 2019	Accruing		Non-Accrual		Total

Consumer and other		136		9		145
Total TDRs	$	8,475	$	1,002	$	9,477

The Company’s policy is to return non-accrual TDR loans to accrual status when all the principal and interest amounts contractually due, pursuant to its modified terms, are brought current and future payments are reasonably assured. Our policy also considers the payment history of the borrower, but is not dependent upon a specific number of payments. The Company recorded a provision for loan loss expense of $31 and partial charge offs of $8 on the TDR loans described above during the three-month period ending March 31, 2019. The Company recorded a provision for loan loss expense of $11 and partial charge-offs of $11 on TDR loans during the three-month period ending March 31, 2018.

Loans are modified to minimize loan losses when we believe the modification will improve the borrower’s financial condition and ability to repay the loan. We typically do not forgive principal. We generally either reduce interest rates or decrease monthly payments for a temporary period of time and those reductions of cash flows are capitalized into the loan balance. We may also extend maturities, convert balloon loans to longer term amortizing loans, or vice versa, or change interest rates between variable and fixed rate. Each borrower and situation is unique and we try to accommodate the borrower and minimize the Company’s potential losses. Approximately 89% of our TDRs are current pursuant to their modified terms, and $1,092, or approximately 11% of our total TDRs are not performing pursuant to their modified terms. There does not appear to be any significant difference in success rates with one type of concession versus another.

One loan with a balance of $713 was modified as a TDR during the three-month period ending March 31, 2019. No loan loss provision was recorded during the three-month period ending March 31, 2019. Loans modified as TDRs during the three-month period ending March 31, 2018 were $1,563. The Company recorded no loan loss provision for loans modified during the three-month period ending March 31, 2018.

Credit Quality Indicators:

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as; current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on at least an annual basis. The Company uses the following definitions for risk ratings:

Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Purchased Credit Impaired (“PCI”) loans:

Income is recognized on PCI loans pursuant to ASC Topic 310-30. A portion of the fair value discount has been ascribed as an accretable yield that is accreted into interest income over the estimated remaining life of the loans. The remaining non-accretable difference represents cash flows not expected to be collected.

The table below summarizes the total contractually required principal and interest cash payments, management’s estimate of expected total cash payments and carrying value of the loans as of March 31, 2019 and December 31, 2018. Contractually required principal and interest payments have been adjusted for estimated prepayments.

The Company adjusted its estimates of future expected losses, cash flows and renewal assumptions during the current quarter. These adjustments resulted in an increase in expected cash flows and accretable yield, and a decrease in the non-accretable difference. The Company reclassified $7,199 and $1,727 from non-accretable difference to accretable yield during the month periods ending March 31, 2019 and 2018 to reflect its adjusted estimates of future expected cash flows.

In the acquisition, the Company acquired $1,141,672 of loans at fair value, net of $23,118, or 2.0%, estimated discount to the outstanding principal balance, representing 23.9% of the Company’s total loans at December 31, 2018. Of the total loans acquired, management identified $11,432 with credit deficiencies. All loans that were on non-accrual status, impaired loans including TDRs and some substandard loans were considered by management to be credit impaired and are accounted for pursuant to ASC Topic 310-30.

The table below summarizes the total contractually required principal and interest cash payments, management’s estimate of expected total cash payments and fair value of the loans as of September 1, 2018 for purchased credit impaired loans. Contractually required principal and interest payments have been adjusted for estimated prepayments.

In its assumption of the deposit liabilities, the Company believed the deposits assumed from the acquisition have an intangible value. The Company applied ASC Topic 805, which prescribes the accounting for goodwill and other intangible assets such as core deposit intangibles, in a business combination. The Company determined the estimated fair value of the core deposit intangible asset totaled $19,795, which will be amortized utilizing an accelerated amortization method over an estimated economic life not to exceed ten years. In determining the valuation amount, deposits were analyzed based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships.

Pro-forma information

Pro-forma data for the three-month period ending March 31, 2018 listed in the table below presents pro-forma information as if the Charter acquisitions occurred at the beginning of 2018.

The disclosures regarding the results of operations Charter subsequent to its respective acquisition date is omitted as this information is not practical to obtain. Although the Company did not convert Charter’s core system until the first quarter of 2019, the majority of the fixed costs and purchase accounting entries were booked on the Company’s core system making it impractical to determine Charter’s results of operation on a stand-alone basis.

NOTE 10: Interest Rate Swap Derivatives

The Company enters into interest rate swaps in order to provide commercial loan clients the ability to swap from fixed to variable interest rates. Under these agreements, the Company enters into a fixed-rate loan with a client in addition to a swap agreement. This swap agreement effectively converts the client’s fixed rate loan into a variable rate. The Company then enters into a matching swap agreement with a third party dealer in order to offset its exposure on the customer swap. At March 31, 2019 and December 31, 2018, the notional amount of such arrangements were $6,194,936 and $5,743,283, respectively. The Company pledged

$91,008 and $28,345 of cash as collateral to the third party dealers at March 31, 2019 and December 31, 2018, respectively. As the interest rate swaps with the clients and third parties are not designated as hedges under ASC 815, changes in market values are reported in earnings.

NOTE 11: Leases

In February 2016, the FASB established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on-balance sheet and disclose key information about leasing arrangements. Subsequently, amendments ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements were issued. ASC 842 establishes a right-of-use (“ROU”) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement.

The Company leases certain properties and equipment under operating leases that resulted in the recognition of ROU Lease Assets of $21,143 and Lease Liabilities of $22,657 on the Company’s Condensed Consolidated Balance Sheets. The one-time transition impact to retained earnings from measurement differences was approximately $1,464 as disclosed on the Company’s Condensed Consolidated Statements of Changes in Stockholders’ Equity.

ASC 842 was effective on January 1, 2019. A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. The Company chose to use the effective date approach. As such, all periods presented after January 1, 2019 are under ASC 842 whereas periods presented prior to January 1, 2019 are in accordance with prior lease accounting of ASC 840. Financial information was not updated and the disclosures required under ASC 842 was not provided for dates and periods before January 1, 2019.

ASC 842 provides a number of optional practical expedients in transition. The Company has elected the ‘package of practical expedients,’ which permits the Company not to reassess under the new standard the prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the use of the hindsight, a practical expedient which permits the use of information available after lease inception to determine the lease term via the knowledge of renewal options exercised not available as of the leases inception. The practical expedient pertaining to land easements is not applicable to the Company.

ASC 842 also requires certain accounting elections for ongoing application of ASC 842. The Company elected the short-term lease recognition exemption for all leases that qualify, meaning those with terms under twelve months. ROU assets or lease liabilities are not to be recognized for short-term leases. However, since all real estate and equipment leases have terms greater than 12 months, no leases currently meet this exemption. The Company also elected the practical expedient to not separate lease and non-lease components for all leases, the majority of which consist of real estate common area maintenance expenses. However, since these non-lease items are subject to change, they are treated and disclosed as variable payments in the quantitative disclosures below. Consequently, ASC 842’s changed guidance on contract components will not significantly affect our financial reporting. Similarly, ASC 842’s narrowed definition of initial direct costs will not significantly affect financial reporting.

Lessee Leases

The majority of the Company’s lessee leases are operating leases, and consist of leased real estate for branches and operations centers. Options to extend and renew leases are generally exercised under normal circumstances. Advance notification is required prior to termination, and any noticing period is often limited to the months prior to renewal. Variable payments generally consist of common area maintenance and taxes. Rent escalations are generally specified by a payment schedule, or are subject to a defined formula. The Company also elected the practical expedient to not separate lease and non-lease components for all leases, the majority of which consist of real estate common area maintenance expenses. Generally, leases do not include guaranteed residual values, but instead typically specify that the leased premises are to be returned in satisfactory condition with the Company liable for damages. The Company also has other operating leases for various equipment, including copiers, printers, and other small equipment.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(in thousands of dollars, except per share data)

Equipment lease terms and conditions generally specify a fixed amount and term with options to renew. The Company’s equipment leases are typically not renewed, and existing leases are typically assumed from prior bank acquisitions.

For operating leases, the lease liability and ROU asset (before adjustments) are recorded at the present value of future lease payments. ASC 842 requires the use of the lease interest rate; however, this rate is typically not known. As an alternative, ASC 842 permits the use of an entity’s fully secured incremental borrowing rate. The Company is electing to utilize the FHLB Atlanta Fixed Rate Advance index, as it is the most actively used institution-specific collateralized borrowing source available to the Company.

The Company also holds a small number of finance leases assumed in connection to prior acquisitions. These leases are all real estate leases. Terms and conditions are similar to those real estate operating leases described above, but the lease terms are generally longer. Lease classifications from the acquired institution were retained, and were again retained as a result of the election of the package of practical expedients described above.

Lessor Leases

ASC 842 also impacted lessor accounting. ASC 842 changed the criteria in which a lessor lease is classified. A lease is a sales-type lease if any one of five criteria are met, each of which indicate that the lease, in effect, transfers control of the underlying asset to the lessee. If none of those five criteria are met, but two additional criteria are both met, indicating that the lessor has transferred substantially all the risks and benefits of the underlying asset to the lessee and a third party, the lease is a direct financing lease. All leases that are not sales-type or direct financing leases are operating leases.

Similar to the above lessee leases, the Company has elected the ‘package of practical expedients,’ which allows the Company not to reassess the Company’s prior conclusions under ASC 842 about lease identification, lease classification and initial direct costs. The Company also elected the use of the hindsight, a practical expedient which permits the use of information available after lease inception to determine the lease term via the knowledge of renewal options exercised not available as of the leases inception. Lastly, the practical expedient pertaining to land easements is not applicable to the Company.

While ASC 842 identifies common area building maintenance as a non-lease component of our real estate lease contracts, the Company elected to account for the Company’s real estate leases and associated common area maintenance service components as a single, combined operating lease component. Consequently, ASC 842’s changed guidance on contract components will not significantly affect financial reporting.

Substantially, all of the Company’s lessor leases are related to unused real estate office space owned by the Company. Most have defined terms, though some leases have gone month-to-month once the initial term has passed. The impact of subleases is not material. Income from operating leases are reported within Occupancy Expense as an offset to Non-interest Expense in the Company’s Condensed Consolidated Statements of Income and Comprehensive Income.

The Company is also the lessor on a few equipment direct finance leases (formerly known as capital leases) with three municipal entities. Interest income from these leases are tax exempt, and is reported within loan interest income. The lessee retains the title to all equipment in each of these finance leases. Each of these leases originated in 2018, and therefore the prior ASC 840 classification was not reassessed due to the election of the package of practical expedients.

NOTE 12: Recently Issued Accounting Standards

In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments.” This ASU significantly changes how entities will measure credit losses for most financial assets and certain other instruments that aren’t measured at fair value through net income. In issuing the standard, the FASB is responding to criticism that today’s guidance delays recognition of credit losses. The standard will replace today’s “incurred loss” approach with an “expected loss” model. The new model, referred to as the current expected credit loss (“CECL”) model, will apply to: (1) financial assets subject to credit losses and measured at amortized cost, and (2) certain off-balance sheet credit exposures. This includes, but is not limited to, loans, leases, held-to-maturity securities, loan commitments, and financial guarantees. The CECL model does not apply to available for sale (“AFS”) debt securities. For AFS debt securities with unrealized losses, entities will measure credit losses in a manner similar to what they do today, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. As a result, entities will recognize improvements to estimated credit losses immediately in earnings rather than as interest income over time, as they do today. The ASU also simplifies the accounting model for purchased credit-impaired debt securities and loans. ASU 2016-13 also expands the disclosure requirements regarding an entity’s assumptions, models, and methods for estimating the allowance for loan and lease losses. In addition, entities will need to disclose the amortized cost balance for each class of financial asset by credit quality indicator, disaggregated by the year of origination. ASU No. 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted for interim and annual reporting periods beginning after December 15, 2018. Entities will apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (i.e., modified retrospective approach). The Company formed a CECL committee to assist with the implementation process. It has selected a third-party vendor to assist with the allowance for loan loss methodology as well as advisory services related to the implementation of the amendments of ASU 2016-13. The Company continues to work with the third-party vendor to develop the CECL model and evaluate the impact to the Company’s Consolidated Financial

CenterState Bank Corporation and Subsidiaries

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(in thousands of dollars, except per share data)

Statements including evaluating the impact from the loans acquired from the recent acquisitions. The standard will add new disclosures related to factors that influenced management’s estimate, including current expected credit losses, the changes in those factors, and reasons for the changes as well as the method applied to revert to historical credit loss experience. The Company expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, but has not yet determined the magnitude of any such one-time adjustment or the overall impact on the Company’s Financial Statements.

In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment,” to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. The Company is currently evaluating the impact of adopting the new guidance on the Consolidated Financial Statements, but it is not expected to have a material impact.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” The amendments in this update more closely align the results of cash flow and fair value hedge accounting with risk management activities through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results in the financial statements. The amendments address specific limitations in current GAAP by expanding hedge accounting for both nonfinancial and financial risk components and by refining the measurement of hedge results to better reflect an entity’s hedging strategies. Thus, the amendments will enable an entity to report more faithfully the economic results of hedging activities for certain fair value and cash flow hedges and will avoid mismatches in earnings by allowing for greater precision when measuring changes in fair value of the hedged item for certain fair value hedges. Additionally, by aligning the timing of recognition of hedge results with the earnings effect of the hedged item for cash flow and net investment hedges, and by including the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is presented, the results of an entity’s hedging program and the cost of executing that program will be more visible to users of financial statements. Overall, those amendments are an improvement because an entity’s financial statements will reflect more accurately and comprehensively the intent and outcome of its hedging strategies. The tabular disclosure related to effects on the income statement of fair value and cash flow hedges and the disclosure of cumulative basis adjustments for fair value hedges provide users with a more complete picture of the effect of hedge accounting on an entity’s income statement and balance sheet. When considered together, the amendments to presentation and disclosures are an improvement because they will provide users with more decision-useful information about the effect of an entity’s risk management activities on the financial statements. Additionally, the amendments in this Update should ease the operational burden of applying hedge accounting by allowing more time to prepare hedge documentation and, allowing effectiveness assessments to be performed on a qualitative basis after hedge inception. For public business entities, the amendments in this update become effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. All transition requirements and elections should be applied to hedging relationships existing (that is, hedging relationships in which the hedging instrument has not expired, been sold, terminated, or exercised or the entity has not removed the designation of the hedging relationship) on the date of adoption. The effect of adoption should be reflected as of the beginning of the fiscal year of adoption (that is, the initial application date). For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the amendments in this Update. The amended presentation and disclosure guidance is required only prospectively. The Company adopted the new accounting guidance effective January 1, 2019, but it did not have a material impact on the Consolidated Financial Statements.

In June 2018, the FASB issued ASU No. 2018-07, “Compensation – Stock Compensation (Topic 718) - Improvements to Nonemployee Share-Based Payment Accounting,” to include share based payment transactions for acquiring goods and services from nonemployees. An entity should apply the requirements of Topic 718 to nonemployee awards except for specific guidance on inputs to an option pricing model and the attribution of cost (that is, the period of time over which share-based payment awards vest and the pattern of cost recognition over that period). The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this update become effective for annual periods and interim periods within those annual periods beginning after December 15, 2018 but no earlier than an entity’s adoption date of Topic 606. The Company adopted the new accounting guidance effective January 1, 2019, but it did not have a material impact on the Consolidated Financial Statements.

In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820) - Changes to the Disclosure Requirements for Fair Value Measurement,” to modify the disclosure requirements on fair value measurements in Topic 820 based on the concepts in the Concepts Statement, including the consideration of costs and benefits. The following disclosure requirements were removed from Topic 820: (1) the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy; (2) the policy for timing of transfers between levels; (3) the valuation processes for Level 3 fair value measurements; and (4) for nonpublic entities, the changes in unrealized gains and losses for the period included in earnings for recurring Level 3 fair value measurements held at the end of the reporting period. The following disclosure requirements were modified in Topic 820: (1) in lieu of a rollforward for Level 3 fair value measurements, a nonpublic entity is required to disclose transfers into and out of Level 3 of the fair value hierarchy and purchases and issues of Level 3 assets and liabilities; (2) for investments in certain entities that calculate net asset value, an entity is required to disclose the timing of liquidation of an investee’s assets and the date when restrictions from redemption might lapse only if the investee has communicated the timing to the entity or announced the timing publicly; and (3) the amendments clarify that the measurement uncertainty disclosure is to communicate information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added to Topic 820: (1) the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period; (2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. For certain unobservable inputs, an entity may disclose other quantitative information (such as the median or arithmetic average) in lieu of the weighted average if the entity determines that other quantitative information would be a more reasonable and rational method to reflect the distribution of unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update are effective for annual periods and interim periods within those annual periods beginning after December 15, 2019. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted upon issuance of this update. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this update and delay adoption of the additional disclosures until their effective date. The Company is currently evaluating the impact of adopting the new guidance on the Consolidated Financial Statements, but it is not expected to have a material impact.

Note 13: Subsequent Events

Completed Acquisition of National Commerce Corporation

On April 1, 2019, the Company completed its previously announced acquisition of National Commerce Corporation (“NCOM”), whereby NCOM merged with and into the Company, with the Company continuing as the surviving corporation in the merger. Immediately after the merger, the Company’s subsidiary bank and NCOM’s subsidiary bank, National Bank of Commerce (“NBC”), merged with CenterState Bank as the surviving bank. Under the terms of the agreement, each outstanding share of NCOM common stock converted into the right to receive 1.65 shares of the Company’s common stock and cash in lieu of any fractional shares of CenterState common stock. The merger consideration, which was mainly comprised of Company common stock, was approximately $825,464. The Company’s primary reasons for the transaction were to expand its core growth markets of Orlando, Tampa, Jacksonville and Atlanta, further solidify its market share in Florida, Georgia and Alabama, expand its customer base to enhance deposit fee income and leverage operating cost through economies of scale. During the three months ended March 31, 2019, the Company incurred approximately $1,264 of acquisition costs related to this transaction. These acquisition costs are reported in merger and acquisition related expenses on the Company’s Consolidated Statements of Income and Comprehensive Income. The majority of the acquisition costs for this transaction are expected to be recorded during the second and third quarters of 2019. Additional disclosures required by ASC 805 have been omitted because the information needed for the disclosures is not available due to the

COMPARISON OF BALANCE SHEETS AT MARCH 31, 2019 AND DECEMBER 31, 2018

Overview

Our total assets increased approximately 2% from December 31, 2018 to March 31, 2019, to approximately $12.6 billion. In addition, loan growth during the period was $8,891 and deposit growth was $269,689, or 12% annualized. Our loan to deposit ratio was 85.7% and 88.0% at March 31, 2019 and December 31, 2018, respectively.

Due to consolidated assets in excess of $10 billion, the Company is now subject to additional regulations and oversight that can affect our revenues and expenses. Such regulations and oversight include increased expectations with respect to risk management internal audit, and information security, enhanced stress testing as a component of liquidity and capital planning, transfer of examination over compliance with consumer and small business laws from the Office of the Comptroller of the Currency to the Consumer Financial Protection Bureau (“CFPB”), increased deposit insurance premium assessments based on a new scorecard issued by the FDIC, and no longer being exempt from the requirements of the Federal Reserve’s rules limiting certain interchange transaction fees for debit cards on institutions over $10 billion in assets. We expect to expend additional resources to comply with these and other additional applicable regulatory requirements. Increased deposit insurance assessments can result in increased expense related to our use of deposits as a funding source. Likewise, a reduction in the amount of interchange fees we receive for electronic debit interchange will reduce our revenues. Finally, a failure to meet prudential risk management and capital planning standards or compliance with consumer lending laws could, among other things, limit our ability to engage in expansionary activities or make dividend payments to our shareholders.

Federal funds sold and Federal Reserve Bank deposits

Federal funds sold and Federal Reserve Bank deposits were $339,223 at March 31, 2019 (approximately 3% of total assets) as compared to $231,981 at December 31, 2018 (approximately 2% of total assets). We use our available for sale securities portfolio, as well as federal funds sold and Federal Reserve Bank deposits for liquidity management and for investment yields. These accounts, as a group, will fluctuate as a function of loans outstanding, and to some degree the amount of correspondent bank deposits (i.e. federal funds purchased) outstanding.

Available for sale debt investments

Available for sale debt securities, consisting primarily of U.S. government sponsored enterprises and municipal tax exempt securities, were $1,701,396 at March 31, 2019 (approximately 14% of total assets) compared to $1,727,348 at December 31, 2018 (approximately 14% of total assets), a decrease of $25,952, which was attributable to a combination of securities sold of $66,480, paydowns received on MBSs of $53,579, net of purchases of $67,661 and unrealized holding gain of $28,875 during current quarter. We use our available for sale debt securities portfolio, as well as federal funds sold and Federal Reserve Bank deposits for liquidity management and for investment yields. These accounts, as a group, will fluctuate as a function of loans outstanding as discussed above, under the caption “Federal funds sold and Federal Reserve Bank deposits.” We classify the majority of our securities as “available for sale debt securities” to provide for greater flexibility to respond to changes in interest rates as well as future liquidity needs. Our available for sale debt securities are carried at fair value.

Trading securities

We also have a trading securities portfolio. Realized and unrealized gains and losses are included in trading securities revenue, a component of our non-interest income, in our Condensed Consolidated Statement of Income and Comprehensive Income. Securities purchased for this portfolio have primarily been various municipal securities. A list of the activity in this portfolio is summarized below.

Held to maturity debt investments

At March 31, 2019, we had $214,240 (unamortized cost basis) of securities with an estimated fair value of $215,175, resulting in a net unrecognized gain of $935, compared to $216,833 (unamortized cost basis) of securities with an estimated fair value of $212,179 and a net unrecognized loss of $4,654 at December 31, 2018. This portfolio generally holds longer term securities for the primary purpose of yield. This classification was chosen to minimize temporary effects on our tangible equity and tangible equity ratio due to increases and decreases in general market interest rates.

Loans held for sale

We also have a mortgage loans held for sale portfolio, whereby we originate single family home loans and sell those mortgages into the secondary market, servicing released. Effective January 1, 2018, the Company elected to account for these loans under the fair value option with changes in fair value recognized in current period earnings. At the date of funding of the loan, the funded amount of the loan, the relative derivative asset or liability of the associated interest rate lock commitment, less direct costs, becomes the initial recorded investment in the loan held for sale. Such amount approximates the fair value of the loan. Net gains from changes in estimated fair value of mortgage loans held for sale were $4 and $363 at March 31, 2019 and 2018, respectively. Gains and losses on the sale of mortgage loans held for sale and changes in fair value are included as a components of mortgage banking revenue which are reported in non-interest income in our Condensed Consolidated Statement of Income and Comprehensive Income.

The table below presents the activity in this portfolio for the periods indicated.

Loans

Lending-related income is the most important component of our net interest income and is a major contributor to profitability. The loan portfolio is the largest component of earning assets, and it therefore generates the largest portion of revenues. The absolute volume of loans and the volume of loans as a percentage of earning assets is an important determinant of net interest margin as loans are expected to produce higher yields than securities and other earning assets. Average loans during the three-month period ended March 31, 2019, were $8,363,073 or 79.0% of average earning assets, as compared to $6,837,979 or 77.1% of average earning assets, for the three-month period ending March 31, 2018. Total loans at March 31, 2019 and December 31, 2018 were $8,349,395 and $8,340,504, respectively. This represents a loan to total asset ratio of 66.3% and 67.6% and a loan to deposit ratio of 85.7% and 88.0%, at March 31, 2019 and December 31, 2018, respectively.

Non-PCI loans

At March 31, 2019, we have total non-PCI loans of $8,199,939. Total new loans originated during the three-month period ended March 31, 2019 approximated $455 million, of which $318 million were funded at the time of origination. About 32% of funded loan origination was non-owner occupied commercial real estate (“CRE”); 18% owner occupied CRE, 22% single family residential, 14% commercial and industrial (“C&I”), 9% land, development & construction and 5% were all other. Approximately 30% of the funded loan production was floating rate, 25% was other variable rate and 45% was fixed rate. The weighted average tax equivalent interest rate on funded loans was approximately 5.34% during the three-month period. The loan origination pipeline is approximately $825 million at March 31, 2019 compared to $683 million at December 31, 2018.

The graph below summarizes new loan originations and funded loan production, excluding acquired loans purchased pursuant to acquisitions, over the past nine quarters.

PCI loans

Total Purchased Credit Impaired (“PCI”) loans at March 31, 2019 were $149,456 compared to $158,971 at December 31, 2018.

Loan concentrations are considered to exist where there are amounts loaned to multiple borrowers engaged in similar activities, which collectively could be similarly impacted by economic or other conditions and when the total of such amounts would exceed 25% of total capital. Due to the lack of diversified industry and the relative proximity of markets served, the Company has concentrations in geographic as well as in types of loans funded.

Total loans at March 31, 2019 were $8,349,395. Of this amount, approximately 83.3% are collateralized by real estate, 14.2% are commercial non real estate loans and the remaining 2.5% are consumer and other non real estate loans. We have $1,818,228 of single family residential loans which represents about 22.0% of our total loan portfolio. Our largest category of loans is commercial real estate which represents approximately 53.7% of our total loan portfolio.

The following table sets forth information concerning the loan portfolio by collateral types as of the dates indicated.

Credit quality and allowance for loan losses

We maintain an allowance for loan losses that we believe is adequate to absorb probable losses incurred in our loan portfolio. The allowance is increased by the provision for loan losses, which is a charge to current period earnings and decreased by loan charge-offs net of recoveries of prior period loan charge-offs. Loans are charged against the allowance when management believes collection of the principal is unlikely.

The allowance consists of three components. The first component consists of amounts reserved for impaired loans, as defined by ASC 310. Impaired loans are those loans that management has estimated will not repay as agreed pursuant to the loan contract. Each of these loans is required to have a written analysis supporting the amount of specific reserve allocated to the particular loan, if any. That is to say, a loan may be impaired (i.e. not expected to repay as agreed), but may be sufficiently collateralized such that we expect to recover all principal and interest eventually, and therefore no specific reserve is warranted.

Commercial, commercial real estate, land, land development and construction loans in excess of $500 are monitored and evaluated for impairment on an individual loan basis. Commercial, commercial real estate, land, land development and construction loans less than $500 are evaluated for impairment on a pool basis. All consumer and single family residential loans are evaluated for impairment on a pool basis.

On at least a quarterly basis, management reviews each impaired loan to determine whether it should have a specific reserve or partial charge-off. Management relies on appraisals to help make this determination. Updated appraisals are obtained for collateral dependent loans when a loan is scheduled for renewal or refinance. In addition, if the classification of the loan is downgraded to substandard, identified as impaired, or placed on nonaccrual status (collectively “Problem Loans”), an updated appraisal is obtained if the loan amount is greater than $500 and individually evaluated for impairment.

After an updated appraisal is obtained for a Problem Loan, as described above, an additional updated appraisal will be obtained on at least an annual basis. Thus, current appraisals for Problem Loans in excess of $500 will not be older than one year.

After the initial updated appraisal is obtained for a Problem Loan and before its next annual appraisal update is due, management considers the need for a downward adjustment to the current appraisal amount to reflect current market conditions, based on management’s analysis, judgment and experience. In an extremely volatile market, we may update the appraisal prior to the one year anniversary date.

The second component is a general reserve on all of our loans other than those identified as impaired and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment and is based on the actual loss history experienced over the most recent two years. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. The portfolio segments identified by the Company are residential loans, commercial real estate loans, construction and land development loans, commercial and industrial and consumer and other. This actual loss experience is supplemented with other economic factors based on the risks present for each portfolio segment. These economic, or qualitative, factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; levels and trends in special mention and substandard loans; and effects of changes in credit concentrations.

The third component consists of amounts reserved for purchased credit impaired loans. On a quarterly basis, we update the amount of loan principal and interest cash flows expected to be collected, incorporating assumptions regarding default rates, loss severities, the amounts and timing of prepayments and other factors that are reflective of current market conditions. Probable decreases in expected loan principal cash flows trigger the recognition of impairment, which is then measured as the present value of the expected principal loss plus any related foregone interest cash flows discounted at the pool’s effective interest rate. Impairments that occur after the acquisition date are recognized through the provision for loan losses. Probable and significant increases in expected principal cash flows would first reverse any previously recorded allowance for loan losses; any remaining increases are recognized prospectively as interest income. The impacts of (i) prepayments, (ii) changes in variable interest rates, and (iii) any other changes in the timing of expected cash flows are recognized prospectively as adjustments to interest income. Disposals of loans, which may include sales of loans, receipt of payments in full by the borrower, or foreclosure, result in removal of the loan from the purchased credit-impaired portfolio. The aggregate of these three components results in our total allowance for loan losses.

In the table below we have shown the components, as discussed above, of our allowance for loan losses at March 31, 2019 and December 31, 2018.

note 1: These are performing acquired loans that were recorded at estimated fair value on the related acquisition dates. The total net unamortized fair value adjustment at March 31, 2019 was approximately $42,909 or 1.10% of the aggregate outstanding related loan balances. Acquired loans currently include performing loans acquired from the TD Bank acquisition (year 2011), the Federal Trust acquisition (year 2011), the Gulfstream Bank acquisition (year 2014), the First Southern Bank acquisition (year 2014), the Community Bank acquisition (year 2016), the Hometown of Homestead Banking Company acquisition (year 2016), the Platinum Bank acquisition (year 2017), the Gateway Bank acquisition (year 2017), the Sunshine Bank acquisition (year 2018), the Harbor Community Bank acquisition (year 2018) and the CharterBank acquisition (year 2018).

note 2: These are loans that were acquired as performing loans that subsequently became impaired.

The general loan loss allowance relating to originated loans decreased by $472. Net changes resulting from a mixture of decreases and increases in the Company’s various two-year historical loss factors and qualitative factors affected the net change in the general loan loss allowance.

The general loan loss allowance relating to acquired loans (non-impaired loans) decreased by $105 resulting primarily from a decline in loans outstanding of $222,505.

The specific loan loss allowance (impaired loans) for both originated loans and acquired loans is the aggregate of the results of individual analyses prepared for each one of the impaired loans, excluding PCI loans. Total impaired loans at March 31, 2019 are equal to $17,477 ($10,665 originated impaired loans plus $6,812 acquired impaired loans).

The Company recorded partial charge offs in lieu of specific allowance for a number of the impaired loans. The Company’s impaired loans have been written down by $1,124 to $17,477 ($15,002 when the $2,475 specific allowance is considered) from their legal unpaid principal balance outstanding of $18,601. In the aggregate, total impaired loans have been written down to approximately 81% of their legal unpaid principal balance, and non-performing impaired loans have been written down to approximately 70% of their legal unpaid principal balance. Approximately $8,247 of the Company’s impaired loans, or 47% of total impaired loans, are accruing performing loans. This group of impaired loans is not included in the Company’s non-performing loans or non-performing assets categories.

PCI loans are accounted for pursuant to ASC Topic 310-30. PCI loan pools are evaluated for impairment each quarter. If a pool is impaired, an allowance for loan loss is recorded. PCI loans had a remaining unpaid principal balance of $204,610 and unamortized fair value adjustment of $55,154, which represents 27% of unpaid principal balance, at March 31, 2019.

The allowance is increased by the provision for loan losses, which is a charge to current period earnings and decreased by loan charge-offs net of recoveries of prior period loan charge-offs. Loans are charged against the allowance when management believes collection of the principal is unlikely. We believe our allowance for loan losses was adequate at March 31, 2019. However, we recognize that many factors can adversely impact various segments of the Company’s markets and customers, and therefore there is no assurance as to the amount of losses or probable losses which may develop in the future.

The tables below summarize the changes in allowance for loan losses during the periods presented.

Nonperforming loans and nonperforming assets

Non-performing loans exclude PCI loans and are defined as non-accrual loans plus loans past due 90 days or more and still accruing interest. Generally, we place loans on non-accrual status when they are past due 90 days and management believes the borrower’s financial condition, after giving consideration to economic conditions and collection efforts, is such that collection of interest is doubtful. When we place a loan on non-accrual status, interest accruals cease and uncollected interest is reversed and charged against current income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Non-performing loans, as defined above, as a percentage of total non-PCI loans, were 0.43% at March 31, 2019, compared to 0.29% at December 31, 2018.

Non-performing assets (which we define as non-performing loans, as defined above, plus (a) OREO (i.e., real estate acquired through foreclosure, in substance foreclosure, or deed in lieu of foreclosure); and (b) other repossessed assets that are not real estate), were $41,475 at March 31, 2019, compared to $26,623 at December 31, 2018. Non-performing assets as a percentage of total assets were 0.33% at March 31, 2019, compared to 0.22% at December 31, 2018. The table below summarizes selected credit quality data at the dates indicated.

note 1:

Excludes PCI loans.

As shown in the table above, the largest component of non-performing loans is non-accrual loans. As of March 31, 2019, the Company had non-accrual loans with an aggregate book value of $35,181 compared to December 31, 2018 when an aggregate book value of $23,567 was reported. The $11,614 increase of non-accrual loans was primarily due to administrative delayed renewals of acquired loans of approximately $9.4 million.

The second largest component of non-performing assets after non-accrual loans is OREO. At March 31, 2019, total OREO was $5,981 compared to $2,909 at December 31, 2018. OREO is carried at the lower of cost or market less the estimated cost to sell. Further declines in real estate values can affect the market value of these assets. Any further decline in market value beyond its cost basis is recorded as a current expense in the Company’s Condensed Consolidated Statement of Income and Comprehensive Income.

Impaired loans are defined as loans that management has determined will not repay as agreed pursuant to the terms of the related loan agreement. Small balance homogeneous loans are not considered for impairment purposes. Once management has determined a loan is impaired, we perform a specific reserve analysis to determine if it is probable that we will eventually collect all contractual cash flows. If management determines that a shortfall is probable, then a specific valuation allowance is placed against the loan. This loan is then placed on non-accrual basis, even if the borrower is current with his/her contractual payments, and will remain on non-accrual until payments collected reduce the loan balance such that it eliminates the specific valuation allowance or equivalent partial charge-down or other economic conditions change. At March 31, 2019, we identified a total of $17,477 in impaired loans, excluding PCI loans. A specific valuation allowance of $2,475 has been attached to $8,437 of impaired loans included in the total $17,477 of identified impaired loans. It should also be noted that the total carrying balance of the impaired loans, or $17,477, has been partially charged down by $1,124 from their aggregate legal unpaid balance of $18,601.

Bank premises and equipment

Bank premises and equipment was $227,182 at March 31, 2019 compared to $227,454 at December 31, 2018, slightly decreased by $272 or 0.1%. Effective January 1, 2019, the Company adopted ASU 842 resulting in the reclassification of $1,353 of branch real estate to ROU Lease Assets as reported on the Company’s Condensed Consolidated Balance Sheet.

A summary of our bank premises and equipment for the period end indicated is presented in the table below.

We transfer branch real estate that is no longer in use to held for sale at estimated fair value less estimated cost to sell and sold. We did not have any branch real estate transfers to held for sale during the three months ending March 31, 2019. Our branch real estate held for sale at March 31, 2019 and December 31, 2018 was $19,483 and $25,080, respectively, a net decrease of $5,597. The net decrease is primarily due to the sale of 5 properties and additional impairment expense of $107 on bank properties previously transferred to held for sale. We received net proceeds of $6,365 for the properties sold during the three-month period ending March 31, 2019.

Leases

In February 2016, the FASB established Topic 842, Leases, by issuing Accounting Standards Update (ASU) No. 2016-02, which requires lessees to recognize leases on the balance sheet and disclose key information about leasing arrangements. Subsequently, amendments ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842, Leases; and ASU No. 2018-11, Targeted Improvements were issued. ASC 842 was effective on January 1, 2019, with a required modified retrospective transition approach by applying ASC 842 to all leases existing at the date of initial application.

ASC 842 establishes a right-of-use (“ROU”) model that requires a lessee to recognize a ROU asset and lease liability on the balance sheet for all leases with a term longer than 12 months. The most significant effects related to the recognition of new ROU assets and lease liabilities on the Company’s balance sheet for our real estate operating leases and, to a much lesser extent, various equipment operating leases. The Company leases certain properties and equipment under operating leases that resulted in the recognition of ROU lease assets of approximately $21 million and lease liabilities of approximately $26 million on the Company’s Condensed Consolidated Balance Sheets. The one-time transition impact to retained earnings from measurement differences was approximately $1.5 million as disclosed on the Company’s Condensed Consolidated Statements of Changes in Stockholders’ Equity. The Company does not expect a significant change in future leasing activities as a result of ASC 842. In addition, the Company does not expect equipment leasing to become a significant source of revenue for the Company.

Interest Rate Swap Derivatives

The Company enters into interest rate swaps in order to provide commercial loan clients the ability to swap from fixed to variable interest rates. Under these agreements, the Company enters into a fixed-rate loan with a client in addition to a swap agreement. This swap agreement effectively converts the client’s fixed rate loan into a variable rate. The Company then enters into a matching swap agreement with a third party dealer in order to offset its exposure on the customer swap. The fair value of interest rate swap derivatives (asset component) was $130,122 at March 31, 2019 compared to $92,475 at December 31, 2018. The fair value of interest rate swap derivatives (liability component) was $130,790 at March 31, 2019 compared to $92,892 at December 31, 2018.

Deposits

Total deposits were $9,747,025 at March 31, 2019 compared to $9,477,336 at December 31, 2018. The total deposits increased $269,689, or approximately 12% on an annualized basis. The cost of interest bearing deposits in the current quarter was 0.84%, compared to 0.76% in the previous quarter. The overall cost of total deposits (i.e. includes non-interest bearing checking accounts) in the current quarter was 0.57% compared to 0.51% in the previous quarter. The table below summarizes the Company’s deposit mix for the periods presented.

Securities sold under agreement to repurchase

Our Bank enters into borrowing arrangements with our retail business customers by agreements to repurchase (“securities sold under agreements to repurchase”) under which the Bank pledges investment securities owned and under their control as collateral against these one-day borrowing arrangement. These short-term borrowings totaled $59,031 at March 31, 2019 compared to $57,772 at December 31, 2018.

Federal funds purchased

Federal funds purchased are overnight deposits including deposits from correspondent banks. At March 31, 2019 we had $303,017 of correspondent bank deposits, compared to $244,360 in overnight correspondent bank deposits and $50,000 in other overnight federal funds purchased at December 31, 2018.

Federal Home Loan Bank advances and other borrowed funds

From time to time, we borrow either through Federal Home Loan Bank (“FHLB”) advances or other borrowings. We had $200,000 in FHLB advances and $11,000 in subordinated notes (assumed from the Sunshine transaction closed on January 1, 2018) at March 31, 2019. At December 31, 2018, the Company had $350,000 in FHLB advances and $11,000 in subordinated notes.

Corporate debentures

Below is a schedule of statutory trust entities and the related corporate debentures formed and assumed through various acquisitions. We assumed $8,000 in corporate debentures pursuant to the acquisition of Harbor on January 1, 2018 and $9,000 in corporate debentures pursuant to the acquisition of Charter on September 1, 2018. The $9,000 corporate debentures assumed from the Charter acquisition were subsequently redeemed in December 2018 at par value with no gains or losses realized on the extinguishments of debt.

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and fully phased in on January 1, 2019. Under these rules, banks are required to maintain a minimum CET1 ratio of 4.5%, a minimum Tier 1 capital to risk-weighted assets of 6%, a total risk-based capital ratio of 8%, and a minimum leverage capital ratio of 4%. In addition, the rules require a capital conservation buffer of up to 2.5% above each of CET1, tier 1, and total risk-based capital which must be met for a bank to be able to pay dividends, engage in share buybacks or make discretionary bonus payments to executive management without restriction. This capital conservation buffer

was being phased in over a four year period starting on January 1, 2016 and was 1.875% in 2018, and is 2.50% as of January 1, 2019. With a full implementation, a banking organization would need to maintain a CET1 capital ratio of at least 7%, a total Tier 1 capital ratio of at least 8.5% and a total risk-based capital ratio of at least 10.5%. The net unrealized gain or loss on available for sale debt securities is not included in computing regulatory capital.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the table below) of total capital, Tier I capital and CET1 (as defined in the regulations) to risk-weighted assets. Management believes, as of March 31, 2019, that the Company and the Bank meet all capital adequacy requirements to which they are subject.

Selected consolidated capital ratios at March 31, 2019 and December 31, 2018 for the Company and the Bank are presented in the tables below. The ratios for capital adequacy purposes do not include capital conservation buffer requirements.

COMPARISON OF RESULTS OF OPERATIONS FOR THE THREE-MONTH PERIODS ENDED MARCH 31, 2019 AND 2018

Overview

We recognized net income of $44,643 or $0.47 per share basic and $0.46 per share diluted for the three-month period ended March 31, 2019, compared to net income of $35,636 or $0.43 per share basic and $0.42 per share diluted for the same period in 2018. A summary of the differences are listed in the table below.

The increase in our net interest income relates primarily to the increase in our average interest earning assets as a result of loan growth and the acquisition of Charter in September 2018. The increase in our “all other non-interest expense,” which represents the operating expenses of our commercial/retail banking segment, is also primarily due to the growth from the acquisition of Charter. These items along with others are discussed and analyzed below.

Our strategy is to grow organically and by acquisition in the southeastern region. In pursuing this strategy, we seek lending teams and companies that are culturally similar to us, that are experienced and are located in our markets or in markets close to us so we can achieve economies of scale. During 2016, we established a new mortgage line of business led by an experienced mortgage lending team, and an SBA business and intend to grow those business lines in our markets, thus increasing our non-interest income. In September 2018, we hired a team of mortgage professionals from State Bank and acquired State Bank’s mortgage loan pipeline. Mortgage banking revenue and SBA revenue combined increased $1,291 during the current quarter compared to the same period in 2018.

Net interest income/margin

Net interest income increased $19,157 or 20.2% to $114,175 during the three-month period ended March 31, 2019 compared to $95,018 for the same period in 2018. The $19,157 increase was the result of a $29,123 increase in interest income offset by $9,966 increase in interest expense.

Interest earning assets averaged $10,579,666 during the three-month period ended March 31, 2019 as compared to $8,866,744 for the same period in 2018, an increase of $1,712,922, or 19.3%. The yield on average interest earning assets increased 35 bps to 5.07% (34 bps to 5.09% tax equivalent basis) during the three-month period ended March 31, 2019, compared to 4.72% (4.75% tax equivalent basis) for the same period in 2018. The combined effects of the $1,712,922 increase in average interest earning assets and the 35 bps (34 bps tax equivalent basis) increase in yield on average interest earning assets resulted in the $29,123 ($29,018 tax equivalent basis) increase in interest income between the two periods.

Interest bearing liabilities averaged $7,124,758 during the three-month period ended March 31, 2019 as compared to $5,765,749 for the same period in 2018, an increase of $1,359,009 or 23.6%. The cost of average interest bearing liabilities was 1.03% during the three-month period ended March 31, 2019, compared to 0.57% for the same period in 2018. The effect of the $1,359,009 increase in average interest bearing liabilities and the 46 bps increase in cost of funds resulted in the $9,966 increase in interest expense between the two periods.

The table below summarizes the analysis of changes in interest income and interest expense for the three-month periods ended March 31, 2019 and 2018 on a tax equivalent basis.

Includes securities sold under agreements to repurchase and Federal Home Loan Bank advances.

note 6:

Represents the average rate earned on interest earning assets minus the average rate paid on interest bearing liabilities (Non-GAAP).

note 7:

Represents net interest income divided by total interest earning assets (Non-GAAP).

note 8:

Interest income and rates include the effects of a tax equivalent adjustment using applicable statutory tax rates to adjust tax-exempt interest income on tax-exempt investment securities and loans to a fully taxable basis (Non-GAAP).

note 9:

PCI loans are accounted for pursuant to ASC 310-30.

note 10:

Includes amortization of fair value adjustments related to various acquisitions of corporate debentures of $88 and $88 for the three-month periods ended March 31, 2019 and 2018.

The primary reason for the increase in our net interest margin (“NIM”) during the current period was due to higher loan yields offset by an increase to the cost of deposits between the two periods presented above. The increase in loan yields is due to originated loan productions at higher yields as well as the impact of loans acquired from Charter and an increase in loan yields.

Provision for loan losses

The provision for loan losses decreased $247 to $1,053 during the three-month period ending March 31, 2019 compared to a provision expense of $1,300 for the comparable period in 2018. Our policy is to maintain the allowance for loan losses at a level

sufficient to absorb probable incurred losses in the loan portfolio. The allowance is increased by the provision for loan losses, which is a charge to current period earnings, and is decreased by charge-offs, net of recoveries on prior loan charge-offs. Therefore, the provision for loan losses (Income Statement effect) is a residual of management’s determination of allowance for loan losses (Balance Sheet approach). In determining the adequacy of the allowance for loan losses, we consider the conditions of individual borrowers, the historical loan loss experience, the general economic environment, the overall portfolio composition, and other information. As these factors change, the level of loan loss provision changes. The decrease in our loan loss provision between the comparable periods is a result of an increase in non-impaired loan balances. See “Credit Quality and Allowance for Loan Losses” for additional information regarding the allowance for loan losses.

Non-interest income

Non-interest income for the three-month ended March 31, 2019 was $29,300 compared to $23,038 for the comparable period in 2018. A summary of the differences are listed in the table below.

	Mar. 31,		Mar. 31,			$ increase			% increase
Three-month periods ending:	2019		2018			(decrease)			(decrease)

note 1:

Includes gross commissions earned on bond sales, fees from hedging services, loan brokering fees and related consulting fees. The fee income in this category is based on sales volume in any particular period and is therefore volatile between comparable periods.

note 2:

Includes fees from safekeeping activities, bond accounting services, asset/liability consulting services, international wires, clearing and corporate checking account services and other correspondent banking related revenue and fees. The fees included in this category are less volatile than those described above in note 1.

Mortgage banking revenue and income from correspondent banking capital markets division increased $1,591 and $1,082, respectively, during the current quarter compared to the same period in 2018. Other increases in non-interest income between the periods presented are mainly attributable to the acquisition of Charter, which was completed in September 2018.

Non-interest expense

Non-interest expense for the three months ended March 31, 2019 increased $8,477, or 11.2%, to $84,473, compared to $75,996 for the same period in 2018. Components of our non-interest expenses are listed in the table below.

The overall primary reason for the increase between the periods presented above relates to the increased salary and wage expenses due to September 2018 acquisition of Charter.

Provision for income taxes

We recognized an income tax expense for the three months ended March 31, 2019 of $13,306 on pre-tax income of $57,949 (an effective tax rate of 23.0%) compared to an income tax expense of $5,124 on pre-tax income of $40,760 (an effective tax rate of 12.6%) for the comparable quarter in 2018. The increase in the effective tax rate is primarily due to $376 in excess tax benefits on stock awards recognized during the three months ended March 31, 2019 compared to $4,539 for the same period in 2018. During the three months ended March 31, 2018, the Company experienced a large volume of stock option exercises pursuant to the assumed stock options from the January 1, 2018 acquisitions of Harbor and Sunshine.

Liquidity

Liquidity is defined as the ability to meet anticipated customer demands for funds under credit commitments and deposit withdrawals at a reasonable cost and on a timely basis. We measure liquidity position by giving consideration to both on- and off-balance sheet sources of and demands for funds on a daily and weekly basis.

Our Bank regularly assesses the amount and likelihood of projected funding requirements through a review of factors such as historical deposit volatility and funding patterns, present and forecasted market and economic conditions, individual client funding needs, and existing and planned business activities. The Bank’s asset/liability committee (ALCO) provides oversight to the liquidity management process and recommends guidelines, subject to the approval of its board of directors, and courses of action to address actual and projected liquidity needs.

Short term sources of funding and liquidity include cash and cash equivalents, net of federal requirements to maintain reserves against deposit liabilities; investment securities eligible for pledging to secure borrowings from customers pursuant to securities sold under repurchase agreements; loan repayments; deposits and certain interest rate-sensitive deposits; and borrowings under overnight federal fund lines available from correspondent banks. In addition to interest rate-sensitive deposits, the primary demand for liquidity is anticipated fundings under credit commitments to customers.

Off-Balance Sheet Arrangements

We do not have any material off-balance sheet arrangements except for approved and unfunded loans and letters of credit to our customers in the ordinary course of business.

Use of Non-GAAP Financial Measures and Ratios

The accounting and reporting policies of the Company conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP performance measures and ratios are used by management to evaluate and measure the Company’s performance. These include tax-equivalent net interest income (including its individual components) and net interest margin (including its individual components). Management believes that these measures and ratios provide users of the Company’s financial information with a more meaningful view of the performance of the interest-earning assets and interest-bearing liabilities. Other financial holding companies may define or calculate these measures differently.

Management reviews yields on certain asset categories and the net interest margin of the Company and its banking subsidiaries on a fully taxable equivalent basis. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis. This measure ensures the comparability of net interest income arising from both taxable and tax-exempt sources.

These disclosures should not be considered in isolation or a substitute for results determined in accordance with GAAP, and are not necessarily comparable to non-GAAP performance measures which may be presented by other financial holding companies. Management compensates for these limitations by providing detailed reconciliations between GAAP information and the non-GAAP financial measures.

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES: MARKET RISK

We believe interest rate risk is the most significant market risk impacting us. We monitor and manage interest rate risk using interest rate sensitivity “gap” analysis to measure the impact of market interest rate changes on net interest income. See our Annual Report on Form 10-K for the fiscal year ended December 31, 2018 for disclosure of the quantitative and qualitative information regarding the interest rate risk inherent in interest rate risk sensitive instruments as of December 31, 2018. There have been no changes in the assumptions used in monitoring interest rate risk as of March 31, 2019. The impact of other types of market risk, such as foreign currency exchange risk and equity price risk, is deemed immaterial.

ITEM 4.

CONTROLS AND PROCEDURES

As of the end of the period covered by this report, an evaluation was carried out under the supervision and with the participation of our management, including the Chief Executive Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) or 15d-15(e)). Based on that evaluation, the CEO and CFO have concluded that our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in reports that we file or submit under the Securities Exchange Act of 1934 are recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) or 15d-15(f)) during the quarter covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
