NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Seacoast Banking Corporation of Florida and Subsidiaries

NOTE A — BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine-month period ended September 30 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 or any other period. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2016.

Use of Estimates

The preparation of these condensed consolidated financial statements required the use of certain estimates by management in determining the Company’s assets, liabilities, revenues and expenses. Actual results could differ from those estimates.

Specific areas, among others, requiring the application of management’s estimates include determination of the allowance for loan losses, the valuation of investment securities available for sale, fair value of impaired loans, contingent liabilities, fair value of other real estate owned, and the valuation of deferred tax assets. Actual results could differ from those estimates.

NOTE B — RECENTLY ISSUED ACCOUNTING STANDARDS, Not adopted as of September 30, 2017

The following provides a brief description of accounting standards that have been issued but are not yet adopted that could affect the Company's financial statements:

In May 2017, the Financial Account Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09, clarifying when changes to the terms of share-based awards, such as value, vesting conditions or classification of the awards, should be accounted for as modifications. All the disclosures about modifications that are currently required would need to be made, along with disclosure of any change (or no change) in compensation expense. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Adoption of this standard is being evaluated as to its effect on the Company’s operating results and financial condition.

In March 2017, the FASB issued ASU 2017-08, requiring entities to amortize premiums on certain purchased callable debt securities to their earliest call date. The accounting for purchased callable debt securities held at a discount did not change. Amortizing the premium to the earliest call date generally aligns interest income recognition with the economics of instruments. This guidance requires a modified retrospective transition under which a cumulative adjustment will be made to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This guidance is effective for fiscal years beginning after December 15, 2018. Adoption of this standard is being evaluated as to its effect on the Company’s operating results or financial condition.

8

In January 2017, the FASB issued ASU 2017-04, eliminating Step 2 from the goodwill impairment test. Under the amendments to the guidance, an entity should perform its 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. The loss recognized, however, 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.  The guidance is effective for annual periods or any interim goodwill impairment tests beginning after December 15, 2019 using a prospective transition method. Early adoption is permitted. Adoption of this standard is being evaluated as to its effect on the Company’s operating results or financial condition.

In August and November 2016, the FASB issued final guidance via ASU 2016-15 and ASU 2016-18, which address classification of certain cash receipts and cash payments, including changes in restricted cash, in the statement of cash flows. The guidance may change how an entity classifies certain cash receipts and cash payments on its statement of cash flows, the purpose being to reduce diversity in practice. The Company is evaluating the impact of ASU 2016-15 and 2016-18 on the Company’s statement of cash flows which will generally be applied retrospectively for fiscal years beginning after December 15, 2017.

In June 2016, the FASB issued ASU 2016-13 for “Measurement of Credit Losses on Financial Instruments” to replace the incurred loss impairment methodology with a current expected credit loss methodology for financial instruments measured at amortized cost and other commitments to extend credit. Expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of voluntary prepayments and considering available information about the collectability of cash flows, including information about past events, current conditions, and supportable forecasts. The resultant allowance for credit losses reflects the portion of the amortized cost basis that the entity does not expect to collect. Additional quantitative and qualitative disclosures are required upon adoption. The Company has established a transition oversight committee that is responsible for assessing expected loss estimation models, data requirements, and changes in processes that will be necessary to meet the requirements of this new accounting guidance. Adoption is required January 1, 2020, with early adoption permitted on January 1, 2019.

In March 2016, under ASU 2016-04, “Liabilities – Extinguishments of Liabilities, Breakage for Certain Prepaid Stored-Value Products” the FASB intends for entities to recognize liabilities for the sale of prepaid stored value products redeemable for goods, services, or cash. This guidance aligns recognition of breakage for these liabilities in a way consistent with how gift card breakage will be recognized. The Company does not expect adoption of this standard to affect the Company’s operating results or financial condition. Effective date for implementation of the guidance is for annual periods after December 15, 2018.

9

In February 2016, the FASB amended existing guidance related to the recognition of lease assets and lease liabilities on the balance sheet and disclosures of key information about leasing arrangements, under ASU 2016-02. The guidance requires all parties to classify leases to determine how to recognize lease-related revenue and expense. The amendment requires lessees to put most leases on their balance sheet and record expenses to the income statement. Changes in the guidance eliminate real estate centric provisions for sale-leaseback transactions, including initial direct costs and lease execution costs for all entities. For lessors, the new FASB standard modifies classification criteria and accounting for sales type and direct financing leases. The Company is currently evaluating the impact of adopting the new guidance on its consolidated financial statements. The amended accounting guidance is applicable to periods after December 15, 2018 and interim periods within that year.

In January 2016, the FASB issued ASU 2016-01 for “Recognition and Measurement of Financial Assets and Liabilities.” The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The update: a) requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value and recognized in net income, b) simplifies impairment assessments of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, and if impaired requires measurement of the investment at fair value, c) eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value, d) requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, e) requires an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, f) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements, and g) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company is evaluating the use of the measurement alternative available for equity securities without a readily determinable fair value, and the related impact to accounting policies, presentation, and disclosures. The ASU is effective for fiscal years beginning after December 15, 2017, and must be adopted on a modified retrospective basis, including interim periods within those fiscal years.

In May 2014, the FASB issued ASU 2014-09, “Revenue Recognition – Revenue from Contracts with Customers.” The ASU is a converged standard between the FASB and the IASB that provides a single comprehensive revenue recognition model for all contracts with customers across transactions and industries. The primary objective of the ASU is revenue recognition that represents the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue associated with loans and securities is not in the scope of the new guidance, and based on the Company’s evaluation to date we do not expect the adoption to have a significant impact on the Company’s operating results or financial condition. The Company continues to evaluate the changes in disclosures required by the new guidance. The Company plans to adopt the new guidance on January 1, 2018.

In 2014, approximately $158.8 million of investment securities available for sale were transferred into held to maturity. The unrealized holding losses at the date of transfer totaled $3.1 million. The unrealized holding losses at the date of the transfer are amortized over the remaining life of these securities as an adjustment of yield in a manner consistent with the amortization of a discount. The amortization of unrealized holding losses reported in other comprehensive income will offset the effect on interest income of the amortization of the discount. At September 30, 2017, the remaining unrealized holding losses from this transfer totaled $1.5 million.

Securities at September 30, 2017 with a fair value of $178.3 million were pledged as collateral for United States Treasury deposits, other public deposits and trust deposits. Securities with a fair value of $142.2 million were pledged as collateral for repurchase agreements at September 30, 2017.

The amortized cost and fair value of securities available for sale and held to maturity at September 30, 2017, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because prepayments of the underlying collateral for these securities may occur, due to the right to call or repay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

The two tables above include securities held to maturity that were transferred from available for sale into held to maturity during 2014. Those securities had unrealized losses of $3.1 million at the date of transfer, and at September 30, 2017, the unamortized balance was $1.5 million. The fair value of those securities in an unrealized loss position for less than twelve months at September 30, 2017 and December 31, 2016 was $6.6 million and $22.8 million, respectively. The additional unrealized losses on those securities in an unrealized loss position for less than twelve months at September 30, 2017 and December 31, 2016 was $0.1 million and $0.4 million, respectively. The fair value of those securities in an unrealized loss position for more than twelve months at September 30, 2017 and December 31, 2016 was $13.1 million and none, respectively. The additional unrealized losses on those securities in an unrealized loss position for more than twelve months at September 30, 2017 and December 31, 2016 was $0.2 million and none, respectively.

At September 30, 2017, unrealized losses on mortgage backed securities, collateralized mortgage obligations and commercial mortgage backed securities of U.S. government sponsored entities having a fair value of $542.0 million totaled $8.8 million, which was attributable to a combination of factors, including relative changes in interest rates since the time of purchase. The contractual cash flows for these securities are guaranteed by U.S. government agencies and U.S. government-sponsored enterprises. Based on our assessment of these factors, management believes that the unrealized losses on these debt security holdings are a function of changes in investment spreads and interest rate movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.

At September 30, 2017, private label securities secured by seasoned residential collateral with a fair value of $22.0 million had approximately $0.4 million in unrealized losses. This was attributable to a combination of factors, including relative changes in interest rates since the time of purchase. The collateral underlying these mortgage investments are 30- and 15-year fixed rate loans and 10/1 adjustable rate mortgage loans with low loan to values, subordination and historically have had minimal foreclosures and losses. Based on its assessment of these factors, management believes that the unrealized losses on these debt security holdings are a function of changes in investment spreads and interest rate movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.

At September 30, 2017, remaining securities categories had unrealized losses of $0.6 million and a fair value of $60.1 million. Management believes that unrealized losses on these remaining debt security holdings are a function of changes in investment spreads and interest movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.

As of September 30, 2017, management does not intend to sell securities that are in unrealized loss positions and it is not more likely than not that the Company will be required to sell these securities before recovery of the amortized cost basis. Therefore, management does not consider any investment to be other-than-temporarily impaired at September 30, 2017.

Included in other assets is $38.6 million of Federal Home Loan Bank and Federal Reserve Bank stock stated at par value. At September 30, 2017, the Company had not identified events or changes in circumstances which may have a significant adverse effect on the ability to redeem these holdings.

The Company also holds 211,330 shares of Visa Class B stock which, following resolution of Visa litigation, will be converted to Visa Class A shares (the conversion rate is 1.6483 shares of Class A stock for each share of Class B stock) for a total of 348,335 shares of Visa Class A stock. Our holdings are related to prior ownership in Visa’s network while Visa operated as a cooperative (11,330 shares), and by acquisition via auctions (200,000 shares) for $6.2 million conducted by the FDIC during the first quarter of 2017. These holdings are reported in other assets in the Consolidated Balance Sheets at the Company’s cost of $6.2 million.

Purchased Loans - PCI loans are accounted for pursuant to ASC Topic 310-30. The excess of cash flows expected to be collected over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan in situations where there is a reasonable expectation about the timing and amount of cash flows expected to be collected. The difference between the contractually required payments and the cash flows expected to be collected, considering the impact of prepayments, is referred to as the nonaccretable difference. We have applied ASC Topic 310-20 accounting treatment to PULs.

The table below summarizes the changes in accretable yield for PCI loans during the three and nine month periods ended September 30, 2017 and 2016, respectively:

The Company utilizes an internal asset classification system as a means of reporting problem and potential problem loans.  Under the Company’s risk rating system, the Company classifies problem and potential problem loans as “Special Mention,” “Substandard,” and “Doubtful” and these loans are monitored on an ongoing basis.  Loans that do not currently expose the Company to sufficient risk to warrant classification in the Substandard or Doubtful categories, but possess weaknesses that deserve management’s close attention are deemed to be Special Mention. Substandard loans include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.  Loans classified as Substandard may require a specific allowance. Loans classified as Doubtful have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.  The principal on loans classified as Doubtful is generally charged off.  Risk ratings are updated any time the situation warrants.

19

Loans that are not problem or potential problem loans are considered to be pass-rated loans and risk grades are recalculated at least annually by the loan relationship manager.  The following tables present the risk category of loans by class of loans based on the most recent analysis performed as of September 30, 2017 and December 31, 2016:

NOTE F — IMPAIRED LOANS AND ALLOWANCE FOR LOAN LOSSES

The Company’s Troubled Debt Restructuring (“TDR”) concessions granted generally do not include forgiveness of principal balances, but may include interest rate reductions, an extension of the amortization period and/or converting the loan to interest only for a limited period of time. Loan modifications are not reported in calendar years after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructuring agreements. Most loans prior to modification were classified as an impaired loan and the allowance for loan losses is determined in accordance with Company policy.

The following table presents loans that were modified during the nine months ended September 30, 2017:

			Pre-		Post-
			Modification		Modification

During the nine months ended September 30, 2017 and 2016, there were no payment defaults on loans that had been modified in a TDR within the previous twelve months. The Company considers a loan to have defaulted when it becomes 90 days or more delinquent under the modified terms, has been transferred to nonaccrual status, or has been transferred to other real estate owned. A defaulted TDR is generally placed on nonaccrual and a specific allowance for loan loss is assigned in accordance with the Company’s policy.

As of September 30, 2017 and December 31, 2016, the Company’s recorded investment in impaired loans (excluding PCI loans), the unpaid principal balance, and the related valuation allowance were as follows:

Impaired loans also include loans that have been modified in TDRs where concessions to borrowers who experienced financial difficulties have been granted. At September 30, 2017 and at December 31, 2016, accruing TDRs totaled $16.2 million and $17.7 million, respectively.

The impaired loans are measured for impairment based on the value of underlying collateral or the present value of expected future cash flows discounted at the loan’s effective rate. The valuation allowance is included in the allowance for loan losses.

Interest payments received on impaired loans are recorded as interest income unless collection of the remaining recorded investment is doubtful at which time payments received are recorded as reductions to principal.

For impaired loans whose impairment is measured based on the present value of expected future cash flows, a total of $169,000 and $282,000 for the three and nine months ended September 30, 2017, respectively, and $83,000 and $176,000 for the three and nine months ended September 30, 2016, respectively, was included in interest income, and this represents the change in present value attributable to the passage of time, and reduces the associated allowance for loan losses.

Nonaccrual loans and accruing loans past due 90 days or more (excluding purchased loans) totaled $10.9 million and $0, respectively, at September 30, 2017, and $11.0 million and $0, respectively, at December 31, 2016. Purchased nonaccrual and accruing loans past due 90 days or more were $3.5 million and $0 million, respectively, at September 30, 2017, and $7.0 million and $0, respectively, at December 31, 2016.

NOTE J — CONTINGENCIES

The Company and its subsidiaries, because of the nature of their businesses, are at all times subject to legal actions, threatened or filed. Management presently believes that none of the legal proceedings to which it is a party are likely to have a material adverse effect on the Company’s consolidated financial condition, operating results or cash flows, although no assurance can be given with respect to the ultimate outcome of any such claim or litigation.

NOTE K — FAIR VALUE

Under ASC 820, fair value measurements for items measured at fair value on a recurring and nonrecurring basis at September 30, 2017 and December 31, 2016 included:

			Quoted Prices

Loans (3)		4,120		0		3,170		950
Other real estate owned (4)		9,949		0		0		9,949

(1) See Note D for further detail of fair value of individual investment categories.

(2) Recurring fair value basis determined using observable market data.

(3) See Note F. Nonrecurring fair value adjustments to loans identified as impaired reflect full or partial write-downs that are based on the loan’s observable market price or current appraised value of the collateral in accordance with ASC 310.

(4) Fair value is measured on a nonrecurring basis in accordance with ASC 360.

The fair value of impaired real estate loans which are collateral dependent is based on recent real estate appraisals less estimated costs of sale. For residential real estate impaired loans, appraised values or internal evaluation are based on the comparative sales approach. These impaired loans are considered level 2 in the fair value hierarchy. For commercial and commercial real estate impaired loans, evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost and/or income approach. A significant unobservable input in the income approach is the estimated capitalization rate for a given piece of collateral. At September 30, 2017, the capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 7.7%. Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time. As such, the fair value of these impaired loans is considered level 3 in the fair value hierarchy. Impaired loans measured at fair value totaled $4.2 million with a specific reserve of $1.4 million at September 30, 2017, compared to $4.1 million with a specific reserve of $0.4 million at December 31, 2016.

29

Fair value of available for sale securities is determined using valuation techniques for individual investments as described in Note D.

When appraisals are used to determine fair value and the appraisals are based on a market approach, the fair value of other real estate owned (“OREO”) is classified as a level 2 input. When the fair value of OREO is based on appraisals which require significant adjustments to market-based valuation inputs or apply an income approach based on unobservable cash flows, the fair value of OREO is classified as Level 3.

Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s monthly and/or quarter-end valuation process.

During the nine months ended September 30, 2017 and 2016, there were no transfers between levels of the fair value hierarchy.

For loans classified as level 3, additions totaled $0.8 million for the first nine months of 2017, consisting of loans that became impaired during 2017. Reductions consisted primarily of principal payments and totaled $0.6 million.

Charge-offs recognized upon loan foreclosures are generally offset by general or specific allocations of the allowance for loan losses and generally do not, and did not during the reported periods, significantly impact the Company’s provision for loan losses.

For OREO classified as level 3 during the first nine months of 2017, foreclosed loans added $0.4 million and migrated branches taken out of service added $1.2 million. Reductions summed to $4.4 million and consisted almost entirely of sales of $4.2 million.

30

The carrying amount and fair value of the Company’s other significant financial instruments that are not measured at fair value on a recurring basis in the balance sheet as of September 30, 2017 and December 31, 2016 is as follows:

The short maturity of Seacoast’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest bearing deposits with other banks, federal funds purchased, and securities sold under agreement to repurchase, maturing within 30 days, and FHLB borrowings.

The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value at September 30, 2017 and December 31, 2016:

Securities: U.S. Treasury securities are reported at fair value utilizing Level 1 inputs. Other securities are reported at fair value utilizing Level 2 inputs. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other factors.

The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. The fair value of collateralized loan obligations is determined from broker quotes. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models.

31

Loans: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial or mortgage. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and nonperforming categories. The fair value of loans, except residential mortgages, is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risks inherent in the loan. For residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusting for prepayment assumptions using discount rates based on secondary market sources. The estimated fair value is not an exit price fair value under ASC 820 when this valuation technique is used.

Loans held for sale: Fair values are based upon estimated values received from independent third party purchasers. These loans are intended for sale and the Company believes that the fair value is the best indicator of the resolution of these loans. Interest income is recorded based on the contractual terms of the loan and in accordance with the Company’s policy on loans held for investment. None of the loans are 90 days or more past due or on nonaccrual as of September 30, 2017 and December 31, 2016, respectively. Loans held for sale were as follows at September 30, 2017 and December 31, 2016:

	September 30,		December 31,
(Dollars in thousands)	2017		2016
Aggregate fair value	$	29,447	$	15,332
Contractual balance		28,782		14,904
Gains		665		428

Deposit Liabilities: The fair value of demand deposits, savings accounts and money market deposits is the amount payable at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for funding of similar remaining maturities.

NOTE L — BUSINESS COMBINATIONS

Acquisition of Floridian Financial Group, Inc.

On March 11, 2016, the Company completed its acquisition of Floridian. Simultaneously, upon completion of the merger, Floridian’s wholly owned subsidiary bank, Floridian Bank, was merged with and into Seacoast Bank. Floridian, headquartered in Lake Mary, Florida, operated 10 branches in Orlando and Daytona Beach, of which several were consolidated with Seacoast locations. This acquisition added approximately $417 million in total assets, $337 million in deposits, and $266 million in loans to Seacoast.

The Company acquired 100% of the outstanding common stock of Floridian. Under the terms of the definitive agreement, Floridian shareholders received, at their election, (i) the combination of $4.29 in cash and 0.5291 shares of Seacoast common stock, (ii) $12.25 in cash, or (iii) 0.8140 shares of Seacoast common stock, subject to a customary proration mechanism so that the aggregate consideration mix equaled 35% cash and 65% Seacoast shares (based on Seacoast’s closing price of $15.47 per share on March 11, 2016).

32

The following table represents the purchase price paid to Floridian shareholders in connection with the acquisition:

	March 11, 2016
Shares exchanged for cash	$	26,699,000
Number of Floridian Financial Group, Inc. common shares outstanding		6,222,119

Value of common stock issued		50,912,791
Total purchase price	$	77,611,791

The acquisition was accounted for under the acquisition method in accordance with ASC Topic 805, Business Combinations. The Company recognized goodwill of $32 million on this acquisition which is nondeductible for tax purposes as this acquisition was a nontaxable transaction. The goodwill was calculated based on the fair values of the assets acquired and liabilities assumed as of the acquisition date. Loans that were nonaccrual and all loan relationships identified as impaired as of the acquisition date were considered by management to be credit impaired and were accounted for pursuant to ASC Topic 310-30.

For the loans acquired we first segregated all acquired loans with specifically identified credit deficiency factor(s). The factors we considered to identify loans as PCI loans were all acquired loans that were nonaccrual, 60 days or more past due, designated as TDRs, graded “special mention” or “substandard.” These loans were then evaluated to determine estimated fair values as of the acquisition date. As required by generally accepted accounting principles, we are accounting for these loans 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 March 11, 2016 for PCI loans. Contractually required principal and interest payments have been adjusted for estimated prepayments.

(In thousands)	March 11, 2016
Contractually required principal and interest	$	8,031
Non-accretable difference		(4,820	)
Cash flows expected to be collected		3,211
Accretable yield		(568	)
Total purchased credit-impaired loan acquired	$	2,643

Loans without specifically identified credit deficiency factors are referred to as Purchased Unimpaired Loans (“PULs”) for disclosure purposes. These loans were then evaluated to determine estimated fair values as of the acquisition date. Although no specific credit deficiencies were identifiable, we believe there is an element of risk as to whether all contractual cash flows will be eventually received. Factors that were considered included the economic environment both nationally and locally as well as the real estate market particularly in Florida. We have applied ASC Topic 310-20 accounting treatment to the PULs.

The Company believes 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. 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.

The acquisition of Floridian constitutes a business combination. Accordingly, the assets acquired and liabilities assumed are presented at their fair values. The determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change, and in some instances rely on use of third party experts.

Acquisition of BMO Harris Central Florida Offices, Deposits and Loans

On June 3, 2016, Seacoast Bank assumed approximately $314 million in deposits related to business and consumer banking customers at a deposit premium of 3.0% of the deposit balances, $63 million in business loans at a loan premium of 0.5%, and fourteen branches of BMO, located in the Orlando Metropolitan Statistical Area (“MSA”).

34

The acquisition is accounted for under the acquisition method in accordance with ASC Topic 805, Business Combinations. Determining fair values of assets and liabilities, especially the loan portfolio and bank premises and leases related to the fourteen branches acquired, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.

At June 3, 2016, no loans acquired from BMO were specifically identified with a credit deficiency factor(s). The factors we consider to identify loans as PCI loans are acquired loans that were nonaccrual, 60 days or more past due, designated as TDR, graded “special mention” or “substandard.” PULs were evaluated to determine estimated fair values as of the acquisition date.

The Company believes 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. In determining the valuation amount, a third party analyzed the deposits based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships.

35

The Company recognized intangibles (including goodwill) of approximately $13 million for this acquisition that are deductible for tax purposes over a 15-year period. The acquisition of BMO’s Orlando banking operations by Seacoast Bank constitutes a business combination. Accordingly, the assets acquired and liabilities assumed are presented at their fair values. The determination of fair value requires management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change, and in some instances rely on use of third party experts.

Acquisition of GulfShore Bancshares, Inc.

On April 7, 2017, the Company completed its acquisition of GulfShore. Simultaneously, upon completion of the merger, GulfShore’s wholly owned subsidiary bank, GulfShore Bank, was merged with and into Seacoast Bank. GulfShore, headquartered in Tampa, Florida, operated 3 branches in Tampa and St. Petersburg, of which all have been retained as Seacoast locations.

The Company acquired 100% of the outstanding common stock of GulfShore. Under the terms of the definitive agreement, GulfShore shareholders received, for each share of Gulfshore common stock, the combination of $1.47 in cash and 0.4807 shares of Seacoast common stock (based on Seacoast’s closing price of $23.94 per share on April 7, 2017).

Value of common stock issued		62,883,030
Total purchase price	$	70,917,029

Merger related charges summed to $4.3 million for the second quarter of 2017, primarily impacting salaries and wages, outsourced data processing costs, and legal and professional fees. All of these costs were expensed in the second quarter of 2017.

The acquisition was accounted for under the acquisition method in accordance with ASC Topic 805, Business Combinations. The Company recognized goodwill of $37 million on this acquisition which is nondeductible for tax purposes as this acquisition was a nontaxable transaction. The goodwill was calculated based on the fair values of the assets acquired and liabilities assumed as of the acquisition date. The fair values initially assigned to assets acquired and liabilities assumed are preliminary and could change for up to one year after the closing date of the acquisition as new information and circumstances relative to closing date fair values are known. Determining fair values of assets and liabilities, especially the loan portfolio and foreclosed real estate, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.

The determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change, and in some instances rely on use of third party experts. These fair value estimates are considered preliminary and are subject to change for up to one year after the closing date of the acquisition as additional information becomes available. For GulfShore, fair values as presented for securities, loans, fixed assets, other real estate owned, and certain other assets and liabilities are necessarily considered preliminary.

The acquisitions of NorthStar and PBCB will be accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. The Company’s assessment of the fair value of assets acquired and liabilities assumed as of the acquisition date is incomplete at the time of this filing; therefore, certain disclosures have been omitted. The Company expects to recognize goodwill in each of these transactions, which is expected to be nondeductible for tax purposes.

THIRD QUARTER 2017

Strategic Overview

Results demonstrate the impact of our digital transformation strategy, successful integration of acquisitions, and disciplined loan growth. Seacoast continues to execute on its plan to grow our core business organically, innovating to build our franchise and increase efficiency, and grow through mergers and acquisitions. We believe that these investments better position us to increase net income to common shareholders today and prospectively.

Third quarter 2017 results and Guidance for 2017

· For the third quarter of 2017, Seacoast reported net income of $14.2 million or $0.32 per average common diluted share, compared to $7.7 million or $0.18 per average common diluted share for the second quarter 2017, and $9.1 million or $0.24 per average common diluted share in the third quarter last year. For the nine months ended September 30, 2017, net income was $29.8 million compared to $18.4 million for nine months ended September 30, 2016. Adjusted net income¹ totaled $15.1 million or $0.35 per average common diluted share for the third quarter of 2017, compared to adjusted net income of $12.7 million or $0.29 per average common diluted share for the second quarter of 2017, and adjusted net income of $11.1 million or $0.29 per average common diluted share a year ago. For the nine months ended September 30, 2017, adjusted net income¹ was $38.1 million compared to $27.3 million for the nine months ended September 30, 2016.

· Our merger with GulfShore Bank in Tampa, Florida in April 2017, and mergers with Northstar in Tampa, Florida in October 2017 and PBCB in West Palm Beach, Florida in November 2017, together with organic and acquisition-related revenue growth momentum and cost reductions, is expected to drive earnings improvement over the balance of 2017 and into 2018.

· The Company is reiterating its previous guidance of $1.28 to $1.32 adjusted earnings per share¹ for full year 2017.

Third Quarter and Year-to-Date 2017 Strategic Highlights

Modernizing How We Sell

· The proportion of deposit accounts opened outside of our banking centers continued to increase, with 13.3% of all deposit accounts opened through our website or 24/7 customer support center during the third quarter.

· We believe we have made significant progress in modernizing our retail and small business sales strategy, focusing on enhancing customer lifetime value. We also began development on a commercial analytics portal that will connect our commercial bankers with the analytics and insights that we have provided our retail and small business teams. This portal will provide daily insight into customer behaviors, emerging customer needs, and suggested opportunities to enhance relationship value.

· We also kicked off a project to improve our loan origination process during the third quarter. This effort will extend well into 2018. Using technology, partners, and lean process improvement we believe we will improve cycle times and strengthen the customer experience.

Lowering Our Cost to Serve

· Mobile penetration increased during the quarter to more than 32% of eligible primary consumer checking customers from 29.5% in September of last year.

· A new record 40% of checks are now deposited outside the banking center network, compared to 35% in September of last year.

· In the first half of 2017, we consolidated five banking center locations. Looking forward into 2018, we expect to continue making progress towards our previously announced goal of reducing our branch footprint by 20% over a 24 to 36-month period.

· Customer adoption of more convenient digital channels continues to grow. In September 2017, our non-teller transactions made up 52% of our total transaction volume, up from 43% two years ago.  We expect this shift in customer preference to continue to accelerate, requiring continued focus on building a digitally integrated business model.

Driving Improvements in How Our Business Operates

· Hurricane Irma tested our disaster recovery plans. Before the storm, we dispatched a team of operations and IT associates to our recovery site in Nashville, Tennessee. This enabled us to continue to operate the bank during and immediately following the storm to ensure our customers had digital and web access at all times. Our back-up customer support center provided uninterrupted, 24/7 customer service.

· We recognized our first full quarter of savings due to the successful renegotiation of our agreement with a key technology and digital services provider. The agreement expands digital banking capabilities, improves service level agreements, and increases our ability to scale.

· In August we announced the consolidation of our customer support center in Stuart. In the fourth quarter we’ll be migrating all customer support operations to our Orlando location which we launched early this year. The new, expanded site supports our 24/7 customer service model and our growth strategy.

43

Scaling and Evolving Our Culture

· During the third quarter we on-boarded key talent in the areas of digital marketing and compliance. We believe these important additions to the Seacoast team help position us for future growth.

Financial Condition

Total assets increased $826.4 million or 18.3% from September 30, 2016 to $5.34 billion at September 30, 2017, driven by organic growth along with the acquisition of GulfShore in April of 2017.

Loan Portfolio

Total loans (net of unearned income and excluding the allowance for loan losses) were $3.38 billion at September 30, 2017, $615.7 million or 22.2% more than at September 30, 2016, and $505.5 million or 17.6% more than at December 31, 2016. The GulfShore acquisition on April 7, 2017 contributed $250.9 million in loans. Also, during the last six months of 2016 and first quarter of 2017, we purchased five separate mortgage loan pools aggregating to $106.5 million, and a marine loan pool of $16.0 million (a total of $122.5 million in loans purchased), and sold two seasoned mortgage portfolio pools (summing to $70.6 million). During the third quarter of 2017, an additional $57.9 million of conforming salable mortgages originated in prior quarters was sold, which resulted in $0.8 million in additional mortgage banking fee income. Loan pools acquired have a weighted average yield of 3.4%, at acquisition with $122.5 million adjustable rate, and contain borrowers with an average FICO score above 740. An $11.0 million Small Business Administration (“SBA”) pool acquired in the second quarter of 2017 has a weighted average yield of 3.0% at acquisition and is zero risk weighted for capital calculations.

44

During the third quarter of 2017, loan production was robust across all categories, despite the disruption of Hurricane Irma. Success in commercial lending through our legacy franchise and through our Accelerate banking model has increased loan growth. Analytics and digital marketing have further fueled loan growth in the consumer and small business channels.

The following tables detail loan portfolio composition at September 30, 2017, December 31, 2016 and September 30, 2016 for portfolio loans, PCI loans and PUL as defined in Note E-Loans.

NET LOAN BALANCES (1)	$	2,272,275	$	13,057	$	484,006	$	2,769,338

(1) Net loan balances at September 30, 2017, December 31, 2016 and September 30, 2016 are net of deferred costs of $12.1 million, $10.6 million, and $10.5 million, respectively.

Note: Commercial real estate includes owner-occupied balances of $688.2 million, $623.8 million, and $609.8 million, for September 30, 2017, December 31, 2016 and September 30, 2016, respectively.

Commercial real estate mortgages increased $184.6 million or 14.3% to $1.48 billion at September 30, 2017, compared to September 30, 2016, a result of improving loan production and loans acquired in the GulfShore merger. Office building loans of $401.7 million or 27.2% of commercial real estate mortgages comprise our largest concentration, with a substantial portion owner-occupied. Portfolio composition also includes lending for retail trade, industrial, healthcare, churches and educational facilities, recreation, multifamily, mobile home parks, lodging, restaurants, agriculture, convenience stores, marinas, and other types of real estate.

45

The Company’s ten largest commercial real estate funded and unfunded loan relationships at September 30, 2017 aggregated to $166.8 million (versus $137.7 million at September 30, 2016), of which $146.4 million was funded. The Company’s 80 commercial real estate relationships in excess of $5 million totaled $694.1 million, of which $559.4 million was funded at September 30, 2017 (compared to 64 relationships of $543.5 million at September 30, 2016, of which $467.5 million was funded).

Fixed rate and adjustable rate loans secured by commercial real estate, excluding construction loans, totaled approximately $1.163 billion and $315 million, respectively, at September 30, 2017, compared to $974 million and $320 million, respectively, at September 30, 2016.

Reflecting the impact of organic loan growth and the Gulfshore loan acquisition, commercial and financial loans (“C&I”) outstanding at September 30, 2017 increased to $535.5 million, up 56.3% from $342.5 million at September 30, 2016. Commercial lending activities are directed principally towards businesses whose demand for funds are within the Company’s lending limits, such as small- to medium-sized professional firms, retail and wholesale outlets, and light industrial and manufacturing concerns. Such businesses are smaller and subject to the risks of lending to small to medium sized businesses, including, but not limited to, the effects of a downturn in the local economy, possible business failure, and insufficient cash flows.

Residential mortgage loans increased $107.8 million or 12.9% from September 30, 2016 to $941.2 million as of September 30, 2017. Substantially all residential originations have been underwritten to conventional loan agency standards, including loans having balances that exceed agency value limitations. During the first quarter of 2017, a $43 million pool of whole loan adjustable rate mortgages with a weighted average yield of 3.2% and average FICO score of 751 was acquired and added to the portfolio. During the third quarter of 2017, $57.9 million of salable, conforming mortgages were sold with a weighted average yield of 3.41%. This sale was deemed an opportunity (given the fall in the 10-year Treasury rate in the quarter) to manage interest rate risk, adjust loan mix to permit growth in construction lending, and to manage on balance sheet liquidity. At September 30, 2017, approximately $431 million or 46% of the Company’s residential mortgage balances were adjustable 1-4 family mortgage loans (including hybrid adjustable rate mortgages). Fixed rate mortgages totaled approximately $298 million (32% of the residential mortgage portfolio) at September 30, 2017, of which 15- and 30-year mortgages totaled $23 million and $184 million, respectively. Remaining fixed rate balances were comprised of home improvement loans totaling $91 million, most with maturities of 10 years or less and home equity lines of credit, primarily floating rates, totaling $213 million at September 30, 2017. In comparison, loans secured by residential properties having fixed rates totaled $152 million at September 30, 2016, with 15- and 30-year fixed rate residential mortgages totaling $25 million and $127 million, respectively, and home equity mortgages and lines of credit totaled $81 million and $154 million, respectively.

The Company also provides consumer loans (including installment loans, loans for automobiles, boats, and other personal, family and household purposes) which increased $39.0 million or 26.8% year over year and totaled $184.5 million (versus $145.5 million at September 30, 2016). Of the $39.0 million increase, $5.0 million was in marine loans, $1.3 million in automobile and truck loans, and $32.7 million in other consumer loans.

At September 30, 2017, the Company had unfunded commitments to make loans of $703 million, compared to $524 million at September 30, 2016.

46

Loan Concentrations

The Company has developed guardrails to manage loan types that are most impacted by stressed market conditions in order to achieve lower levels of credit loss volatility in the future. Commercial and commercial real estate loan relationships greater than $10 million totaled $321.5 million and represented 9% of the total portfolio at September 30, 2017, compared to $161.7 million or 13% at year-end 2010.

Concentrations in total construction and land development loans and total CRE loans are maintained well below regulatory limits. Construction and land development and commercial real estate loan concentrations as a percentage of total risk based capital, were stable at 50% and 207%, respectively, at September 30, 2017. Regulatory guidance suggests limits of 100% and 300%, respectively.

The Company defines commercial real estate in accordance with the guidance on “Concentrations in Commercial Real Estate Lending” (the “Guidance”) issued by the federal bank regulatory agencies in 2006, which defines commercial real estate (“CRE”) loans as exposures secured by land development and construction, including 1-4 family residential construction, multi-family property, and non-farm nonresidential property where the primary or a significant source of repayment is derived from rental income associated with the property (i.e. loans for which 50 percent or more of the source of repayment comes from third party, non-affiliated, rental income) or the proceeds of the sale, refinancing, or permanent financing of the property. Loans to real estate investment trusts, or “REITs”, and unsecured loans to developers that closely correlate to the inherent risks in CRE markets would also be considered CRE loans under the Guidance. Loans on owner occupied CRE are generally excluded.

Nonperforming Loans, Troubled Debt Restructurings, Other Real Estate Owned, and Credit Quality

Nonperforming assets (“NPAs”) at September 30, 2017 totaled $21.5 million, and were comprised of $10.9 million of nonaccrual portfolio loans, $3.5 million of nonaccrual purchased loans, $1.7 million of non-acquired other real estate owned (“OREO”), $1.6 million of acquired OREO and $3.8 million of branches out of service. NPAs decreased from $31.2 million recorded as of September 30, 2016 (comprised of $10.6 million of nonaccrual portfolio loans, $7.9 million of nonaccrual purchased loans, $3.7 million of non-acquired OREO, $1.5 million of acquired OREO, and $7.6 million of branches out of service). At September 30, 2017, approximately 96% of nonaccrual loans were secured with real estate. See the tables below for details about nonaccrual loans. At September 30, 2017, nonaccrual loans were written down by approximately $3.4 million or 19% of the original loan balance (including specific impairment reserves). During the twelve months ended September 30, 2017, OREO amounts related to branches taken out of service that are actively being marketed decreased $3.8 million, total OREO for foreclosed properties declined $1.9 million, and nonaccrual purchased loans were $4.4 million lower.

Nonperforming loans to total loans outstanding at September 30, 2017 decreased to 0.42% from 0.52% at June 30, 2017 and from 0.67% at September 30, 2016. Nonperforming assets to total assets declined to 0.40% at September 30, 2017 from 0.49% at June 30, 2017 and 0.69% one year ago.

47

The Company’s loss mitigation staff handles all foreclosure actions together with outside legal counsel.

The Company pursues loan restructurings in selected cases where it expects to realize better values than may be expected through traditional collection activities. The Company has worked with retail mortgage customers, when possible, to achieve lower payment structures in an effort to avoid foreclosure. TDRs have been a part of the Company’s loss mitigation activities and can include rate reductions, payment extensions and principal deferrals. Company policy requires TDRs that are classified as nonaccrual loans after restructuring remain on nonaccrual until performance can be verified, which usually requires six months of performance under the restructured loan terms. Accruing restructured loans totaled $16.2 million at September 30, 2017 compared to $19.3 million at September 30, 2016. Accruing TDRs are excluded from our nonperforming asset ratios. The tables below set forth details related to nonaccrual and accruing restructured loans.

At September 30, 2017 and 2016, total TDRs (performing and nonperforming) were comprised of the following loans by type of modification:

	2017				2016
(Dollars in thousands)	Number		Amount		Number		Amount
Rate reduction		72	$	13,340		83	$	14,817
Maturity extended with change in terms		52		5,888		57		7,157
Chapter 7 bankruptcies		29		1,964		38		2,376
Not elsewhere classified		11		1,256		12		1,594
		164	$	22,448		190	$	25,944

During the first nine months of 2017, newly identified TDRs totaled $67,000, compared to $2.0 million for all of 2016. Loan modifications are not reported in calendar years after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructuring agreements. No accruing loans that were restructured within the twelve months preceding September 30, 2017 defaulted during the twelve months ended September 30, 2017, or for 2016. A restructured loan is considered in default when it becomes 60 days or more past due under the modified terms, has been transferred to nonaccrual status, or has been transferred to OREO.

48

At September 30, 2017, loans (excluding PCI) totaling $30.0 million were considered impaired (comprised of total nonaccrual, loans 90 days or more past due, and TDRs) and $2.1 million of the allowance for loan losses was allocated for potential losses on these loans, compared to $29.7 million and $2.0 million, respectively, at September 30, 2016.

In accordance with regulatory reporting requirements, loans are placed on nonaccrual following the Retail Classification of Loan interagency guidance.  Typically loans 90 days or more past due are reviewed for impairment, and if deemed impaired, are placed on nonaccrual.  Once impaired, the current fair market value of the collateral is assessed and a specific reserve and/or charge-off taken. Quarterly thereafter, the loan carrying value is analyzed and any changes are appropriately made as described above.

Cash and Cash Equivalents and Liquidity Risk Management

Cash and cash equivalents (including interest bearing deposits), totaled $125.3 million at September 30, 2017, compared to $167.4 million at September 30, 2016 and $109.6 million at December 31, 2016. The issuance of common stock during the first quarter of 2017 was a primary contributor to the increase in cash and cash equivalents from year-end 2016.

Liquidity risk involves the risk of being unable to fund assets with the appropriate duration and rate-based liability, as well as the risk of not being able to meet unexpected cash needs. Liquidity planning and management are necessary to ensure the ability to fund operations cost effectively and to meet current and future potential obligations such as loan commitments and unexpected deposit outflows.

Funding sources primarily include customer-based core deposits, collateral-backed borrowings, cash flows from operations, cash flows from our loan and investment portfolios and asset sales (primarily secondary marketing for residential real estate mortgages and marine financings). Cash flows from operations are a significant component of liquidity risk management and we consider both deposit maturities and the scheduled cash flows from loan and investment maturities and payments.

Deposits are also a primary source of liquidity. The stability of this funding source is affected by numerous factors, including returns available to customers on alternative investments, the quality of customer service levels, perception of safety and competitive forces. We routinely use securities and loans as collateral for secured borrowings. In the event of severe market disruptions, we have access to secured borrowings through the FHLB and the Federal Reserve Bank of Atlanta under its borrower-in-custody.

49

Contractual maturities for assets and liabilities are reviewed to meet current and expected future liquidity requirements. Sources of liquidity, both anticipated and unanticipated, are maintained through a portfolio of high quality marketable assets, such as residential mortgage loans, securities held for sale and interest-bearing deposits. The Company is also able to provide short term financing of its activities by selling, under an agreement to repurchase, United States Treasury and Government agency securities not pledged to secure public deposits or trust funds. At September 30, 2017, the Company had available unsecured lines of $75 million and lines of credit under current lendable collateral value, which are subject to change, of $815 million. The Company had $366 million of United States Treasury and Government agency securities and mortgage backed securities not pledged and available for use under repurchase agreements, and had an additional $488 million in residential and commercial real estate loans available as collateral. In comparison, at September 30, 2016, the Company had available unsecured lines of $50 million and lines of credit of $783 million, and had $753 million of Treasury and Government agency securities and mortgage backed securities not pledged and available for use under repurchase agreements, as well as an additional $375 million in residential and commercial real estate loans available as collateral.

The Company does not rely on and is not dependent on off-balance sheet financing or significant amounts of wholesale funding. During the first, second and third quarters of 2017, the Company acquired an additional $57.9 million, $82.3 million and $133.5 million of brokered certificates of deposit (“CDs”), respectively, at a rate of 1.18%, 1.27% and 1.39%, respectively, all maturing within 12 months. Brokered CDs at September 30, 2017 totaled $281.6 million.

The Company has traditionally relied upon dividends from its bank subsidiary and securities offerings to provide funds to pay the Company’s expenses and to service the Company’s debt. At September 30, 2017, without OCC approval Seacoast Bank can pay dividends to the Company of approximately $61 million. At September 30, 2017, the Company had cash and cash equivalents at the parent of approximately $55.4 million, compared to $14.2 million at September 30, 2016, with the increase directly related to the capital raise completed on February 21, 2017.

Securities

Information related to maturities, carrying values and fair value of the Company’s securities is set forth in “Note D – Securities” of the Company’s condensed consolidated financial statements.

At September 30, 2017, the Company had no trading securities, $996.8 million in securities available for sale, and $374.8 million in securities held to maturity. The Company's total securities portfolio increased $112.8 million or 9.0% from September 30, 2016. During the first quarter of 2016, securities totaling $66.9 million were added from the acquisition of Floridian. Security purchases during the first and second quarter of 2016 of $258.3 million were primarily to utilize anticipated cash to be received by Seacoast from the acquisition of BMO branches, with an increase of $203.4 million in securities held to maturity during the second quarter (almost a doubling from the first quarter of 2016). Security purchases during the third quarter of 2016 were more limited, totaling only $13 million, and totaled $130 million in the fourth quarter of 2016, $43 million in the first quarter of 2017, $213 million in the second quarter of 2017, and $35 million in the third quarter of 2017. Securities acquired from GulfShore in the second quarter of 2017 were nominal. These efforts were primary to the overall increase in the securities portfolio during 2016 and 2017. Funding for investments was derived from liquidity, both legacy and that acquired in mergers, and increases in funding from our core customer deposit base, brokered time deposits and FHLB borrowings.

50

During the first nine months of 2017, sales of securities resulted in proceeds of $7.6 million (including net losses of $26,000). In comparison, proceeds from the sales of securities totaled $38.8 million (including net gains of $361,000) for the nine months ended September 30, 2016. Management believes the securities sold had minimal opportunity to further increase in value.

Securities are generally acquired which return principal monthly. The modified duration of the investment portfolio at September 30, 2017 was 4.1 years, compared to 3.8 years at September 30, 2016. Securities that are fixed rate comprise 66% of the total investment portfolio, with remaining securities in the portfolio adjustable rate, or 34% of the total portfolio.

At September 30, 2017, available for sale securities had gross unrealized losses of $7.3 million and gross unrealized gains of $6.9 million, compared to gross unrealized losses of $3.6 million and gross unrealized gains of $11.8 million at September 30, 2016. All of the securities with unrealized losses are reviewed for other-than-temporary impairment at least quarterly. As a result of these reviews it was determined that the securities with unrealized losses are not other than temporarily impaired and the Company has the intent and ability to retain these securities until recovery over the periods presented (see additional discussion under “Other Fair Value Measurements” and “Other than Temporary Impairment of Securities” in “Critical Accounting Policies and Estimates”).

Company management considers the overall quality of the securities portfolio to be high. The Company has no exposure to securities with subprime collateral. The Company does not have an investment position in trust preferred securities.

Deposits and Borrowings

The Company’s balance sheet continues to be primarily core funded.

Total deposits increased $602.1 million or 17.2% to $4.11 billion at September 30, 2017, compared to September 30, 2016. Excluding the GulfShore acquisition and addition of $273.7 million in brokered CDs, total deposits increased $43.1 million or 1.2% from September 30, 2016. Also, at September 30, 2017, total deposits excluding Gulfshore deposits and the $273.7 million of brokered CDs decreased $12.8 million or 0.4% (not annualized) from year-end 2016. Deposit growth since year-end 2016 was partially offset by seasonal declines in public fund balances, which decreased by $101.6 million during the first nine months of 2017.

Since September 30, 2016, interest bearing deposits (interest bearing demand, savings and money markets deposits) increased $209.1 million or 10.6% to $2.19 billion, noninterest bearing demand deposits increased $115.6 million or 9.9% to $1.28 billion, and CDs increased $277.5 million or 75.9% to $643.1 million. Excluding acquired deposits, noninterest demand deposits were $45.8 million or 3.9% higher from September 30, 2016, and represent 31.2% of total deposits, compared to 33.3% at September 30, 2016. Core deposit growth reflects our success in growing households both organically and through acquisitions.

Additions to CDs and the increase in CDs at September 30, 2017 year over year have come primarily through the Gulfshore acquisition in April 2017 and brokered CDs acquired during 2017. An intentional decrease in higher cost time deposits was recorded over the two years prior to the 2016 BMO branch acquisition, and was more than offset by increases in low cost or no cost deposits.

51

Customer repurchase agreements totaled $142.2 million at September 30, 2017, decreasing $25.5 million or 15.2% from September 30, 2016. The repurchase agreements are offered by Seacoast to select customers who wish to sweep excess balances on a daily basis for investment purposes. Public funds comprise a significant amount of the outstanding balance.

No unsecured federal funds purchased were outstanding at September 30, 2017 or 2016.

At September 30, 2017 and 2016, borrowings were comprised of subordinated debt of $70.5 million and $70.2 million, respectively, related to trust preferred securities issued by trusts organized or acquired by the Company, and borrowings from FHLB of $389.0 million and $305.0 million, respectively. At September 30, 2017 and 2016, our FHLB borrowings were all maturing within 30 days, and the rate for FHLB funds during the third quarter of 2017 was 1.17%. At December 31, 2016, FHLB borrowings totaled $415.0 million, and were similarly short-term and maturing within 30 days. Secured FHLB borrowings are an integral tool in liquidity management for the Company.

The Company has two wholly owned trust subsidiaries, SBCF Capital Trust I and SBCF Statutory Trust II that were both formed in 2005. In 2007, the Company formed an additional wholly owned trust subsidiary, SBCF Statutory Trust III. The 2005 trusts each issued $20.0 million (totaling $40.0 million) of trust preferred securities and the 2007 trust issued an additional $12.0 million in trust preferred securities. As part of the BANKshares acquisition in 2014, the Company inherited three junior subordinated debentures totaling $5.2 million, $4.1 million, and $5.2 million, respectively. Also, as part of the Grand acquisition in 2015, the Company inherited an additional junior subordinated debenture totaling $7.2 million. The acquired junior subordinated debentures (in accordance with ASU 805 Business Combinations) were recorded at fair value, which collectively is $4.8 million lower than face value at September 30, 2017. This amount is being amortized into interest expense over the acquired subordinated debts’ remaining term to maturity. All trust preferred securities are guaranteed by the Company on a junior subordinated basis.

Under Basel III and Federal Reserve rules, qualified trust preferred securities and other restricted capital elements can be included as Tier 1 capital, within limitations. The Company believes that its trust preferred securities qualify under these capital rules. The weighted average interest rate of our outstanding subordinated debt related to trust preferred securities was 3.59% for the third quarter of 2017, compared to 2.93% for the third quarter ended September 30, 2016.

Off-Balance Sheet Transactions

In the normal course of business, we may engage in a variety of financial transactions that, under generally accepted accounting principles, either are not recorded on the balance sheet or are recorded on the balance sheet in amounts that differ from the full contract or notional amounts. These transactions involve varying elements of market, credit and liquidity risk.

Lending commitments include unfunded loan commitments and standby and commercial letters of credit. A large majority of loan commitments and standby letters of credit expire without being funded, and accordingly, total contractual amounts are not representative of our actual future credit exposure or liquidity requirements. Loan commitments and letters of credit expose the Company to credit risk in the event that the customer draws on the commitment and subsequently fails to perform under the terms of the lending agreement.

52

Loan commitments to customers are made in the normal course of our commercial and retail lending businesses. For commercial customers, loan commitments generally take the form of revolving credit arrangements. For retail customers, loan commitments generally are lines of credit secured by residential property. These instruments are not recorded on the balance sheet until funds are advanced under the commitment. For loan commitments, the contractual amount of a commitment represents the maximum potential credit risk that could result if the entire commitment had been funded, the borrower had not performed according to the terms of the contract, and no collateral had been provided. Loan commitments were $703 million at September 30, 2017 and $524 million at September 30, 2016.

Capital Resources

The Company’s equity capital at September 30, 2017 increased $158.9 million from September 30, 2016 to $594.4 million, and increased $159.0 million from December 31, 2016. On February 21, 2017, the Company closed on an offering of 8,912,500 shares of common stock, consisting of 2,702,500 shares sold by the Company and 6,210,000 shares sold by one of its shareholders. Seacoast received proceeds (net of expenses) of $55.7 million from the issuance of the 2,702,500 shares of its common stock. The Company intends to use the net proceeds from the offering for general corporate purposes, including acquisitions completed, or underway, potential future acquisitions, and to support organic growth. Seacoast did not receive any proceeds from the sale of its shareholder’s shares (see “Note I – Shareholders’ Equity”).

The Company also issued 2,626,693 common shares in the acquisition of GulfShore that was consummated on April 7, 2017 (see “Note L – Business Combinations”). This transaction increased shareholders’ equity $62.9 million, as the Company issued shares of common stock as consideration for the merger.

The ratio of shareholders’ equity to period end total assets was 11.13% and 9.65% at September 30, 2017 and 2016, respectively. Equity has also increased as a result of earnings retained by the Company. During 2016, the ratio of shareholders’ equity to total assets declined, as the Company successfully grew assets at a faster pace than equity over the period.

Activity in shareholders’ equity for the nine months ended September 30, 2017 and 2016 follows:

(Dollars in thousands)	2017		2016
Beginning balance at December 31, 2016 and 2015	$	435,397	$	353,453
Net income		29,818		18,431

Capital ratios are well above regulatory requirements for well-capitalized institutions. Seacoast’s management uses risk-based capital measures to assess the quality of capital and believes that investors may find it useful in their analysis of the Company. The capital measures are not necessarily comparable to similar capital measures that may be presented by other companies (see “Note I –Equity Capital”).

September 30, 2017:

	Seacoast			Seacoast			Minimum to be
	(Consolidated)			Bank			Well Capitalized*
Common equity Tier 1 ratio (CET1)		12.32	%		12.38	%		6.5	%
Tier 1 capital ratio		14.06	%		12.38	%		8.0	%
Total risk-based capital ratio		14.75	%		13.07	%		10.0	%
Tier 1 leverage ratio		10.29	%		9.06	%		5.0	%

* For subsidiary bank only

The Company’s total risk-based capital ratio was 14.75% at September 30, 2017, an increase from June 30, 2017’s ratio of 14.56%, and an increase from September 30, 2016’s ratio of 13.41%. Higher earnings in the third quarter of 2017 was the primary contributor to increases in Tier 1 and total risk-based capital ratios since June 30, 2017. The capital raise during 2017 was the primary cause of these ratios improving, compared to prior year at September 30, 2016.

The Company and Seacoast Bank are subject to various general regulatory policies and requirements relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The appropriate federal bank regulatory authority may prohibit the payment of dividends where it has determined that the payment of dividends would be an unsafe or unsound practice. The Company is a legal entity separate and distinct from Seacoast Bank and its other subsidiaries, and the Company’s primary source of cash and liquidity, other than securities offerings and borrowings, is dividends from its bank subsidiary. Without Office of the Comptroller of the Currency (“OCC”) approval, Seacoast Bank can pay $61.0 million of dividends to the Company.

The OCC and the Federal Reserve have policies that encourage banks and bank holding companies to pay dividends from current earnings, and have the general authority to limit the dividends paid by national banks and bank holding companies, respectively, if such payment may be deemed to constitute an unsafe or unsound practice. If, in the particular circumstances, either of these federal regulators determine that the payment of dividends would constitute an unsafe or unsound banking practice, either the OCC or the Federal Reserve may, among other things, issue a cease and desist order prohibiting the payment of dividends by Seacoast Bank or us, respectively. Under a recently adopted Federal Reserve policy, the board of directors of a bank holding company must consider different factors to ensure that its dividend level is prudent relative to the organization’s financial position and is not based on overly optimistic earnings scenarios such as any potential events that may occur before the payment date that could affect its ability to pay, while still maintaining a strong financial position. As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company, such as Seacoast, should consult with the Federal Reserve and eliminate, defer, or significantly reduce the bank holding company’s dividends if: (i) its net income available to shareholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (ii) its prospective rate of earnings retention is not consistent with its capital needs and overall current and prospective financial condition; or (iii) it will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios.

54

The Company has seven wholly owned trust subsidiaries that have issued trust preferred stock. Trust preferred securities from our acquisitions were recorded at fair value when acquired. All trust preferred securities are guaranteed by the Company on a junior subordinated basis. The Federal Reserve’s rules permit qualified trust preferred securities and other restricted capital elements to be included under Basel III capital guidelines, with limitations, and net of goodwill and intangibles. The Company believes that its trust preferred securities qualify under these revised regulatory capital rules and believes that it can treat all $70.5 million of trust preferred securities as Tier 1 capital. For regulatory purposes, the trust preferred securities are added to the Company’s tangible common shareholders’ equity to calculate Tier 1 capital.

The Company’s capital is expected to continue to increase with positive earnings.

Results of Operations

Earnings Overview

In early September, the State of Florida was preparing for the potential impact of dangerous category 5 Hurricane Irma. This caused a full two weeks of business interruption as a week was spent on preparation and a week on recovery. Ultimately, the storm made landfall in the Florida Keys as a category 4 storm and a second landfall in Marco Island in southwest Florida. The impact of Hurricane Irma on the quarter was approximately $0.01 per share. Revenue was impacted in the form of waived service charges, slower activity in wealth management, and delayed closings on loans. Direct expenses totaled $0.4 million, comprised of compensation for staff working throughout the storm to ensure our customers had digital and web access at all times, remote support from our backup site in Nashville, Tennessee, and recovery expenses to bring our branch network back on-line. These direct incremental expenses were removed from the presentation of adjusted results. Our branches and operations facilities suffered no meaningful damage.

The Company has steadily improved results over the past three years and into 2017. Net income was $14.2 million, or $0.32 per average common diluted share, compared to $7.7 million or $0.18 for the prior quarter and $9.1 million or $0.24 for the third quarter of 2016. For the nine months ended September 30, 2017, net income was $29.8 million compared to $18.4 million for the nine months ended September 30, 2016. Adjusted net income¹ was $15.1 million, or $0.35 per average common diluted share, compared to $12.7 million or $0.29 per average common diluted share for the prior quarter and $11.1 million or $0.29 per average common diluted share for the third quarter of 2016. For the nine months ended September 30, 2017, adjusted net income¹ was $38.1 million compared to $27.3 million for the nine months ended September 30, 2016.

Data analytics and technology-assisted operational improvement are helping us build efficiencies across our organization and drive process automation. We believe that our success in increasing net income is the result of our success in significantly growing our businesses and balance sheet, while attaining operating efficiency. We believe our improved earnings also reflect the success we have had in identifying and incorporating acquisitions, including our recent acquisition of GulfShore on April 7, 2017, providing three offices in Tampa, Florida (see “Note L – Business Combinations”).

Net revenues for the quarter ended September 30, 2017 were $57.2 million, an increase of $2.6 million or 5% compared to the prior quarter, and an increase of $9.7 million or 21% from the third quarter of 2016. For the nine months ended September 30, 2017, net revenues were $159.9 million, an increase of $29.9 million or 23% compared to the nine months ended September 30, 2016. For the nine months ended September 30, 2017, adjusted revenues¹ were $159.9 million, an increase of $30.7 million or 24% compared to the nine months ended September 30, 2016.

For the third quarter of 2017, net gains on the sale of other real estate owned and repossessed assets compared to a net loss for the second quarter of 2017, with a net gain of $414,000 in the third quarter of 2017, and net losses of $161,000 in the second quarter of 2017. The primary contributor to gains in the third quarter was the sale of closed branches transferred to OREO.

This report contains financial information determined by methods other than Generally Accepted Accounting Principles (“GAAP”), including adjusted net income tax, tax equivalent net interest income and margin, and adjusted noninterest expense and efficiency ratios. The most directly comparable GAAP measures are net income, net interest income, net interest margin, noninterest expense, and efficiency ratios. Management uses these non-GAAP financial measures in its analysis of the Company’s performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance. The Company believes the non-GAAP measures enhance investors’ understanding of the Company’s business and performance and if not provided would be requested by the investor community. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently. The Company provides reconciliations between GAAP and these non-GAAP measures. These disclosures should not be considered an alternative to GAAP.

Effective in the first quarter of 2017, adjusted net income and adjusted noninterest expense exclude the effect of amortization of acquisition-related intangibles. Prior periods have been revised to conform to the current period presentation.

Net Interest Income and Margin

Net interest income for the quarter totaled $45.7 million, increasing $1.6 million or 4% during the third quarter of 2017 compared to second quarter 2017’s result, and was $8.3 million or 22% higher than third quarter 2016. Net interest margin was 3.74% in the third quarter 2017 compared to 3.84% for second quarter 2017 and 3.69% for prior year’s third quarter. The second quarter of 2017 benefited from accretion of $1.5 million associated with early payoffs on securities and acquired loans, which added 13 basis points to the margin. Loan growth, balance sheet mix and yield/cost management have been the primary forces affecting net interest income and net interest margin results. Acquisitions have further accelerated these trends. Organic loan growth of $365 million or 13.2% since September 30, 2016, and the addition of loans of $251 million from the GulfShore purchase, all contributed to the net interest income improvement year over year for the third quarter. Net interest income for 2017 will continue to benefit from the full year impact of acquisitions completed in 2016, as well as from the GulfShore, NorthStar and PBCB acquisitions.

The following table details the trend for net interest income and margin results (on a tax equivalent basis)⁽¹⁾, the yield on earning assets and the rate paid on interest bearing liabilities for the past five quarters:

	Net Interest		Net Interest			Yield on			Rate on Interest
(Dollars in thousands)	Income (1)		Margin (1)			Earning Assets (1)			Bearing Liabilities
Third quarter 2016	$	37,735		3.69	%		3.90	%		0.30	%
Fourth quarter 2016		37,628		3.56			3.78			0.31
First quarter 2017		38,377		3.63			3.88			0.35
Second quarter 2017		44,320		3.84			4.12			0.41
Third quarter 2017		45,903		3.74			4.10			0.51

⁽¹⁾ On tax equivalent basis, a non-GAAP measure. See "Non-GAAP Measures regarding Net Interest Income and Margin”.

While the yield on earning assets remained close to second quarter 2017’s result, declining 2 basis points to 4.10%, the rate paid on interest bearing liabilities increased 10 basis points over the same period to 0.51%. The addition of $134 million in broker CDs at a weighted average rate of 1.39%, and an increase of 20 basis points in the rate paid on FHLB borrowings were primary contributors to the increase in rate paid on interest bearing liabilities. A steepening of the Treasury yield curve, higher short term rates, and higher yields on the securities and loan portfolios have benefited the Company’s margin results over the past twelve months.

Looking forward and inclusive of NorthStar and PBCB, we expect the net interest margin to be in the mid 3.70s in the fourth quarter of 2017 and to increase to the high 3.70s by the second quarter of 2018, assuming no change in short or long-term interest rates.

Total average loans increased $687.3 million or 25% for third quarter 2017 compared to 2016’s third quarter, and increased $140.6 million or 4% from second quarter 2017 (non-annualized). Our average investment securities also increased $89.8 million or 7% for third quarter 2017 year over year and were higher by $93.4 million or 7% (non-annualized) from 2017’s second quarter.

57

Average loans (the highest yielding component of earning assets) as a percentage of average earning assets totaled 70.0% during the third quarter of 2017, compared to 66.9% a year ago. As average total loans as a percentage of earning assets increased, the mix of loans has remained fairly stable, with volumes related to commercial real estate representing 47.3% of total loans at September 30, 2017 (compared to 50.1% at September 30, 2016)(see “Loan Portfolio”).

Loan production is detailed in the following table for the last five quarters:

	Quarters

Consumer and small business originations		86,954		97,858		89,546		83,484		87,815

Consumer and small business originations reached $87 million during the third quarter of 2017 and commercial loans closed totaled $146 million. Closed residential loans retained during the quarter totaled $74 million, reflecting continued strong performance. During the third quarter of 2017, the Company sold $58 million of salable conforming residential mortgages, included in the $104 million of residential loans sold in the table above.

Pipelines (loans in underwriting and approval or approved and not yet closed) remained strong at $155 million in commercial, $64 million in mortgage, and $47 million in consumer and small business, even with Hurricane Irma as a disruption in September. Commercial pipelines increased $9.0 million or 6%, over second quarter 2017 and $36.0 million or 30%, compared to September 30, 2016. Mortgage pipelines were $7.7 million or 10% lower, compared to second quarter 2017, and declined $15.4 million or 19%, from September 30, 2016. Consumer and small business pipelines decreased from second quarter by $2.7 million or 5%, but increased from September 30, 2016 by $5.6 million or 13%.

The addition of a new commercial team, focused on specialized equipment financing, and the GulfShore team into our lending business in the second quarter of 2017 supplemented the commercial pipeline and commercial loans closed during the third quarter of 2017, and the addition of NorthStar and PBCB provides an additional opportunity to further grow our balance sheet prospectively.

Deposit growth reflects our success in growing households both organically and through acquisitions. The Company’s balance sheet continues to be primarily core deposit funded. Core customer funding increased to $3.612 billion at September 30, 2017, a 1% decrease from June 30, 2017, but a 9% increase from September 30, 2016. Excluding acquisitions, core customer funding increased by $41 million, or 1%, from one year ago, with noninterest bearing deposits increasing 4%. Seacoast’s overall cost of deposits is 0.22%, higher than second quarter 2017 by 5 basis points and compared to 0.15% in prior year’s third quarter. Prospectively, total deposits are expected to increase 6% on an annualized basis.

Short-term borrowings were entirely comprised of sweep repurchase agreements with Seacoast Bank customers at September 30, 2017 and 2016. No federal funds purchased were utilized at September 30, 2017 or 2016. The average yield on customer repurchase accounts was 0.49% for the third quarter 2017.

FHLB borrowings, maturing in 30 days or less, totaled $389.0 million at September 30, 2017, with an average rate of 1.17% paid during the quarter. FHLB borrowings averaged $439.8 million for the third quarter of 2017, up from $323.8 million for the second quarter of 2017 and $223.5 million for the third quarter 2016.

For the third quarter 2017, average subordinated debt of $70.4 million related to trust preferred securities issued by subsidiary trusts of the Company (including subordinated debt for Grand and BANKshares assumed on July 17, 2015 and October 1, 2014, respectively) carried an average cost of 3.59%.

We have a positive interest rate gap and our net interest margin should benefit from rising interest rates. Further increases in interest rates are likely, and the Company’s asset sensitivity is further enhanced by its low cost deposit portfolio (see “Interest Rate Sensitivity”).

The following table details average balances, net interest income and margin results (on a tax equivalent basis) (1) for the third quarter of 2017, the second quarter of 2017, and the third quarter of 2016.

Non-GAAP Measures regarding Net Interest Income and Margin

Fully taxable equivalent net interest income is a common term and measure used in the banking industry but is not a term used under GAAP. We believe that these presentations of tax-equivalent net interest income and tax equivalent net interest margin aid in the comparability of net interest income arising from both taxable and tax-exempt sources over the periods presented. We further believe these non-GAAP measures enhance investors’ understanding of the Company’s business and performance, and facilitate an understanding of performance trends and comparisons with the performance of other financial institutions. The limitations associated with these measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might calculate these measures differently, including as a result of using different assumed tax rates. These disclosures should not be considered as an alternative to GAAP. The following information is provided to reconcile GAAP measures and tax equivalent net interest income and net interest margin on a tax equivalent basis.

Noninterest Income

Noninterest income (excluding securities gains or losses) totaled $11.5 million for the third quarter of 2017, $1.0 million or 10% higher than 2017’s second quarter and $1.7 million or 18% higher than third quarter 2016. For the nine months ended September 30, 2017, noninterest income totaled $31.9 million, 16% higher than the nine months ended September 30, 2016. For the third quarter 2017, noninterest income accounted for 20.1% of total revenue (net interest income plus noninterest income, excluding securities gains), compared to 19.2% for the second quarter of 2017 and 20.7% for the third quarter a year ago.

Noninterest income (excluding security gains) for the third quarter of 2017, compared to second quarter 2017 and the third quarter of 2016, and for the nine months ended September 30, 2017 and 2016, is detailed as follows:

	Third		Second		Third		Nine Months Ended

Total	$	11,481	$	10,467	$	9,764	$	31,853	$	27,505

For the third quarter of 2017, most categories of service fee income showed year over year growth compared to 2016’s third quarter, with mortgage banking fees increasing 13.4%, interchange income up 12.0%, BOLI income higher by 118.8%, and other income rising 81.1%. These increases reflect continued strength in customer acquisition and cross sell and benefits from acquisition activity. Interchange revenue is dependent upon business volumes transacted, as well as the fees permitted by VISA^® and MasterCard^®.

Service charges on deposits for the third quarter of 2017 increased 7.8% from second quarter 2017, but were 2.7% lower compared to third quarter a year ago. During the third quarter of 2017, post-hurricane Irma accommodations for customers included the waiver of fees where circumstances were appropriate. This goodwill gesture reinforced our standard of commitment to our customers and the markets we serve.

Wealth management, including brokerage commissions and fees, and trust income, increased 2.7% during the third quarter of 2017, compared to prior year’s third quarter. For the nine month period ended September 30, 2017, wealth management income was 4.6% lower compared to 2016. While trust income increased 17.9% from the third quarter of 2016, brokerage commissions and fees were 24.2% lower, reflecting a shift toward fee-based accounts. Despite recent decreases, we expect wealth management revenues to grow over time.

Salable mortgage production was higher during the third quarter of 2017 compared to 2016’s third quarter (see “Loan Portfolio”), and the incremental sale of $57.9 million of conforming mortgages originated in prior quarters, generated total fees that were 13.4% higher, compared to 2016’s third quarter. The incremental sale added $0.8 million to mortgage banking gains for the third quarter 2017. Nine month results for 2017 were $0.7 million or 16.8% higher than a year ago. Mortgage banking fees (excluding the incremental sale) were generally lower during the third and second quarters of 2017, compared to the first quarter of 2017 and prior quarters, the result of shifting consumer demand to construction product and tight inventory levels of homes for sale. Originated residential mortgage loans are processed by commissioned employees of Seacoast, with many mortgage loans referred by the Company’s branch personnel.

62

BOLI income was significantly higher for third quarter 2017 compared to 2016’s third quarter, due to additional purchases of BOLI in the fourth quarter of 2016 and the third quarter of 2017 that increased the BOLI asset to $119 million, and increased income in the third quarter 2017 by 118.8% compared to third quarter 2016. For the nine months ended September 30, 2017, income was higher but to a lesser degree, by 45.2% compared to the first nine months of 2016, in part due to the recognition of a death benefit of $0.5 million in the first quarter of 2016. The addition of $30 million in BOLI late in the third quarter of 2017 will provide a first-year tax equivalent rate of return of 6.2%. Higher income is expected to benefit the Company over the remainder of 2017 and prospectively.

Marine finance fees for the third quarter of 2017 were flat compared to third quarter a year ago. For the nine month period ended September 30, 2017, marine financing fees were 7.0% higher than a year ago, reflecting stronger demand for marine vessels and a strategic shift to selling more production.

Other income was 81.1% higher year over year for third quarter 2017. For the first nine months of 2017, other income was 64.1% higher than the first nine months of 2016. Of the increase of $0.8 million for the third quarter of 2017, $0.3 million was in swap related income with loan customers, $0.2 million in Small Business Administration (“SBA”) loan secondary market activity, and $0.2 million for income generated by factoring fees related to asset lending. A general increase in other fee categories also occurred year over year, the result of pricing increases implemented across the franchise on a number of services offered.

Noninterest Expenses

Noninterest expenses for the third quarter of 2017 totaled $34.4 million, decreasing $7.3 million compared to the second quarter of 2017, and were $0.9 million higher than third quarter 2016. For the nine months ended September 30, 2017, noninterest expense was $110.7 million compared to $100.6 million for the nine months ended September 30, 2016.

Noninterest expenses for the third quarter of 2017, compared to second quarter 2017 and the third quarter of 2016, and for the nine months ended September 30, 2017 and 2016, is detailed as follows:

For the third quarter of 2017 compared to second quarter 2017, expenses associated with branch consolidation initiatives were $2.0 million less and merger related charges incurred were $4.6 million lower, but business continuity expenses related to Hurricane Irma were incremental, adding $0.4 million. Merger related charges in the second quarter of 2017 primarily related to the acquisition of GulfShore Bank in April 2017.

Adjusted noninterest expense¹ (a non-GAAP measure, see table below for a reconciliation to noninterest expense, the most comparable GAAP number) was $32.8 million, compared to $33.8 million in the second quarter of 2017, and $30.1 million in the prior year’s third quarter. For the nine months ended September 30, 2017, adjusted noninterest expense¹ was $97.6 million compared to $85.4 million for the nine months ended September 30, 2016. Noninterest expense includes the addition during the second quarter of 2017 of ongoing headcount and expenses associated with our new Tampa market operations totaling $1.1 million. A gain of $414,000 on other real estate owned in the third quarter of 2017 compared to a net loss of $161,000 in the second quarter of 2017. Outsourced data processing costs in the second and third quarters of 2017 reflect the value of our renegotiated contract with our core processing vendor.

(1) Non-GAAP measures. The most directly comparable GAAP measures are noninterest expense and efficiency ratio, respectively.

(2) Efficiency ratio is defined as (noninterest expense less foreclosed property expense and amortization of intangibles) divided by the net operating revenue (net interest on a fully tax equivalent basis plus noninterest income excluding securities gains).

*Includes severance, contract termination costs, disposition of branch premises and fixed assets, and other costs to effect our branch consolidation and other expense reduction strategies.

Prospectively, Seacoast management expects its efficiency ratio to improve, entering 2018 in the mid-50’s. The Company expects its digital servicing capabilities and technology to continue to support better, more efficient channel integration, allowing consumers to choose their path of convenience to satisfy their banking needs, resulting in organic growth of our products and services as well as related revenue. The third quarter of 2017 highlights the underlying adjusted noninterest expense¹ run rate of the Company exclusive of the two acquisitions completed in the fourth quarter. In aggregate, the acquisitions of NorthStar and PBCB will add $1.6 million in noninterest expense to the fourth quarter of 2017, and $2.0 million per quarter in 2018. We continue to carefully balance investments with current earnings, and the Company anticipates making investments totaling approximately $4.5 million in 2018 to improve our processes and tools for commercial banking, invest in talent and tools for our enterprise risk management and technology functions, and further upgrade our analytics and digital marketing capabilities. These investments will help to scale our organization appropriately, and set the stage for sustainable earnings growth in 2019 and beyond. These investments are not expected to impact our objective of completing 2018 with an adjusted efficiency ratio in the low 50s.

Total occupancy, furniture and equipment expenses for the third quarter of 2017 totaled $3.6 million, decreasing $2.5 million or 40.4% (on an aggregate basis) from second quarter 2017 and $1.3 million or 25.8% from 2016’s third quarter. For the nine months ended September 30, 2017, these expenses were $0.5 million or 3.5% higher than the nine months ended September 30, 2016. Branch closure charges summed to $1.9 million during the second quarter of 2017. We believe branches are still valuable to our customers for more complex transactions, but simple tasks, such as depositing and withdrawing funds, are rapidly migrating to a digital world. During the third quarter of 2017, deposits outside of the branch network increased to 40% from 35% in the same quarter one year prior. Our goal at the beginning of 2017 was to close 20% of our locations over the next 24 to 36 months. We consolidated one location during the first quarter of 2017 and four additional locations in the second quarter of 2017. Looking forward into 2018, we expect to continue making progress towards our goal of branch consolidation. Some of the operational expense savings will be reinvested into technology and talent to deliver products and services in new more convenient ways.

Seacoast Bank utilizes third parties for its core data processing systems and outsourced data processing costs are directly related to the number of transactions processed. Outsourced data processing costs totaled $3.2 million for the third quarter of 2017, a decrease of $0.2 million or 6.5% from second quarter 2017 and nominally higher from the third quarter a year ago. Outsourced data processing expense were $0.5 million or 4.6% lower for the nine months ended September 30, 2017, compared to a year ago. One-time charges for conversion activity related to the acquisition of Floridian in the first quarter of 2016 and GulfShore in the second quarter of 2017 are included.

Legal and professional fees totaled $2.6 million for the third quarter of 2017, compared to $3.3 million for the second quarter of 2017 and $2.2 million for the third quarter in 2016, and totaled $8.0 million for the first nine months of 2017 compared to $7.2 million during same period in 2016, respectively. Legal fees were $0.5 million lower in the third quarter of 2017 compared to the second quarter of 2017, reflecting a reduction in acquisition related costs and outlays for other matters.

Changes in remaining categories, including marketing, FDIC assessments, and asset disposition expense were less significant.

Other expense totaled $3.4 million for the third quarter of 2017, decreasing by $0.5 million or 13.8% compared to second quarter 2017 and lower by $0.2 million or 6.7% compared to third quarter 2016’s expense. Year-to-date through September 30, 2017, other expense was $1.0 million or 9.7% higher than for the nine months ended September 30, 2016. Contributing to the $1.0 million increase year over year for the nine month period were the following: miscellaneous losses and charge-offs (up $0.2 million from 2016), director fees (higher by $0.2 million), employee placement fees (increasing $0.1 million), credit information (up $0.1 million), and bank meetings (rising $0.3 million versus 2016).

Income Taxes

For the first, second and third quarters of 2017, provision for income taxes totaled $4.1 million, $3.9 million and $7.9 million, respectively. Various tax strategies have been implemented to reduce the Company’s overall effective tax rate year-to-date to 34.9% for 2017. Additionally, ASU 2016-09 provided a tax benefit of $702,000 included in 2017’s provision for taxes for the first nine months. Management believes all of the future tax benefits of the Company’s deferred tax assets can be realized and no valuation allowance is required.

Critical Accounting Policies and Estimates

The Company’s consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, (“GAAP”), including prevailing practices within the financial services industry. The preparation of consolidated financial statements requires management to make judgments in the application of certain of its accounting policies that involve significant estimates and assumptions. We have established policies and control procedures that are intended to ensure valuation methods are well controlled and applied consistently from period to period. These estimates and assumptions, which may materially affect the reported amounts of certain assets, liabilities, revenues and expenses, are based on information available as of the date of the financial statements, and changes in this information over time and the use of revised estimates and assumptions could materially affect amounts reported in subsequent financial statements. Management, after consultation with the Company’s Audit Committee, believes the most critical accounting estimates and assumptions that involve the most difficult, subjective and complex assessments are:

66

• the allowance and the provision for loan losses;

• acquisition accounting and purchased loans;

• intangible assets and impairment testing;

• other fair value adjustments;

• other than temporary impairment of securities;

• realization of deferred tax assets; and

• contingent liabilities.

The following is a discussion of the critical accounting policies intended to facilitate a reader’s understanding of the judgments, estimates and assumptions underlying these accounting policies and the possible or likely events or uncertainties known to us that could have a material effect on our reported financial information.

Allowance and Provision for Loan Losses – Critical Accounting Policies and Estimates

Management determines the provision for loan losses by continuously analyzing and monitoring delinquencies, nonperforming loan levels and the outstanding balances for each loan category, as well as the amount of net charge-offs, for estimating losses inherent in its portfolio. While the Company’s policies and procedures used to estimate the provision for loan losses charged to operations are considered adequate by management, factors beyond the control of the Company, such as general economic conditions, both locally and nationally, make management’s judgment as to the adequacy of the provision and allowance for loan losses approximate and imprecise (see “Nonperforming Assets”).

The provision for loan losses is the result of a detailed analysis estimating for probable loan losses. The analysis includes the evaluation of impaired and purchased credit impaired loans as prescribed under FASB Accounting Standards Codification (“ASC”) 310, Receivables as well as an analysis of homogeneous loan pools not individually evaluated as prescribed under ASC 450, Contingencies. For the first, second and third quarters of 2017, the Company recorded provisioning for loan losses of $1.3 million, $1.4 million and $0.7 million, respectively, which compared to provisioning for loan losses for the first, second and third quarters of 2016 of $0.2 million, $0.7 million and $0.6 million, respectively. The Company had net charge-offs of $271,000 in the first nine months of 2017, compared to net recoveries for 2016’s first nine months of ($2,321,000), representing 0.01% and (0.12%) of year-to-date average total loans. Lower provisioning for loan losses in the third quarter of 2017 reflects continued strong credit metrics, decreases in the residential loan portfolio (with lower modeled loss rates given near-zero historical losses and lower balances after the $57.9 million sale near the end of the quarter), and decreases reflecting reduced concentration risk in the commercial and commercial real estate loan portfolios. Delinquency trends remain low and show continued stability (see section titled “Nonperforming Loans, Troubled Debt Restructurings, Other Real estate Owned, and Credit Quality”).

67

The allowance for loan losses increased $2.8 million to $26.2 million at September 30, 2017, compared to $23.4 million at December 31, 2016. The allowance for loan and lease losses (“ALLL”) framework has four basic elements: (1) specific allowances for loans individually evaluated for impairment; (2) general allowances for pools of homogeneous non-purchased loans (“portfolio loans”), which are not individually evaluated; (3) specific allowances for purchased impaired loans which are individually evaluated based on the loans expected principal and interest cash flows; and (4) general allowances for purchased unimpaired pools of homogeneous loans that have similar risk characteristics. The aggregate of these four components results in our total ALLL.

The first component of the ALLL analysis involves the estimation of an allowance specific to individually evaluated impaired portfolio loans, including accruing and non-accruing restructured commercial and consumer loans. In this process, a specific allowance is established for impaired loans based on an analysis of the most probable sources of repayment, including discounted cash flows, liquidation or operation of the collateral, or the market value of the loan itself. It is the Company’s policy to charge off any portion of the loan deemed uncollectable. Restructured consumer loans are also evaluated and included in this element of the estimate. As of September 30, 2017, the specific allowance related to impaired portfolio loans individually evaluated totaled $2.1 million, compared to $2.5 million as of December 31, 2016. Residential loans that become 90 days past due are placed on nonaccrual and a specific allowance is made for any loan that becomes 120 days past due. Residential loans are subsequently written down if they become 180 days past due and such write-downs are supported by a current appraisal, consistent with current banking regulations.

The second component of the ALLL analysis, the general allowance for homogeneous portfolio loan pools not individually evaluated, is determined by applying factors to pools of loans within the portfolio that have similar risk characteristics. The general allowance is determined using a baseline factor that is developed from an analysis of historical net charge-off experience. These baseline factors are developed and applied to the various portfolio loan pools. Adjustments may be made to baseline reserves for some of the loan pools based on an assessment of internal and external influences on credit quality not fully reflected in the historical loss experience. These influences may include elements such as changes in concentration, macroeconomic conditions, and/or recent observable asset quality trends.

The third component consists of amounts reserved for purchased credit-impaired loans (PCI). On a quarterly basis, the Company updates 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 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 loan’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.

68

The final component consists of amounts reserved for purchased unimpaired loans (PUL). Loans collectively evaluated for impairment reported at September 30, 2017 include loans acquired from GulfShore on April 7, 2017, BMO Harris on June 3, 2016, Floridian Bank on March 11, 2016, Grand Bank on July 17, 2015 and BANKshares on October 1, 2014 that are not PCI loans. These loans are performing loans recorded at estimated fair value at the acquisition date. These fair value discount amounts are accreted into income over the remaining lives of the related loans on a level yield basis, and remained adequate at September 30, 2017.

Our analysis of the adequacy of the allowance for loan losses also takes into account qualitative factors such as credit quality, loan concentrations, internal controls, audit results, staff turnover, local market conditions, employment levels and loan growth.

During the first quarter of 2017, management enhanced its processes for evaluating the adequacy of the general reserve components of the allowance for loan losses due to the increasing size and complexity of the commercial loan portfolio. Using a third-party software tool, the enhanced process applies a migration model to portfolio segments that allows us to observe performance over time, and the ability to separately analyze sub-segments based on vintage, risk rating, and origination tactics. Previously, an analysis was based on an average loss rate for various lookback periods.

These enhancements provide a more reliable estimate of probable losses in the portfolio, improve the efficiency of the process for preparing the analysis, and provide the foundation for moving to a current expected credit loss approach. This change in accounting estimate was implemented on January 1, 2017 and had no material impact on the allowance for loan losses.

The allowance as a percentage of portfolio loans outstanding (excluding PCI and PUL loans) was 0.91% at September 30, 2017, compared to 0.96% at December 31, 2016. The risk profile of the loan portfolio reflects adherence to credit management methodologies to execute a low risk strategic plan for loan growth. New loan production is focused on adjustable rate residential real estate loans, owner-occupied commercial real estate, small business loans for professionals and businesses, as well as consumer lending. Strategies, processes and controls are in place to ensure that new production is well underwritten and maintains a focus on smaller, diversified and lower-risk lending.

Concentrations of credit risk, discussed under the caption “Loan Portfolio” of this discussion and analysis, can affect the level of the allowance and may involve loans to one borrower, an affiliated group of borrowers, borrowers engaged in or dependent upon the same industry, or a group of borrowers whose loans are predicated on the same type of collateral. At September 30, 2017, the Company had $1.063 billion in loans secured by residential real estate and $1.602 billion in loans secured by commercial real estate, representing 31.4% and 47.3% of total loans outstanding, respectively. In addition, the Company is subject to a geographic concentration of credit because it primarily operates in central and southeastern Florida.

69

It is the practice of the Company to ensure that its charge-off policy meets or exceeds regulatory minimums. Losses on unsecured consumer loans are recognized at 90 days past due, compared to the regulatory loss criteria of 120 days. In compliance with Federal Financial Institution Examination Council guidelines, secured consumer loans, including residential real estate, are typically charged-off or charged down between 120 and 180 days past due, depending on the collateral type. Commercial loans and real estate loans are typically placed on nonaccrual status when principal or interest is past due for 90 days or more, unless the loan is both secured by collateral having realizable value sufficient to discharge the debt in-full and the loan is in process of collection. Secured loans may be charged-down to the estimated value of the collateral with previously accrued unpaid interest reversed. Subsequent charge-offs may be required as a result of changes in the market value of collateral or other repayment prospects. Initial charge-off amounts are based on valuation estimates derived from appraisals, broker price opinions, or other market information. Generally, new appraisals are not received until the foreclosure process is completed; however, collateral values are evaluated periodically based on market information and incremental charge-offs are recorded if it is determined that collateral values have declined from their initial estimates.

While it is the Company’s policy to charge off in the current period loans in which a loss is considered probable, there are additional risks of future losses that cannot be quantified precisely or attributed to particular loans or classes of loans. Because these risks include the state of the economy, borrower payment behaviors and local market conditions as well as conditions affecting individual borrowers, management’s judgment of the allowance is necessarily approximate and imprecise. The allowance is also subject to regulatory examinations and determinations as to adequacy, which may take into account such factors as the methodology used to calculate the allowance for loan losses and the size of the allowance for loan losses in comparison to a group of peer companies identified by the regulatory agencies. Management will consistently evaluate the allowance for loan losses methodology and seek to refine and enhance this process as appropriate. As a result, it is likely that the methodology will continue to evolve over time.

Note F to the financial statements (titled “Impaired Loans and Allowance for Loan Losses”) summarizes the Company’s allocation of the allowance for loan losses to construction and land development loans, commercial and residential estate loans, commercial and financial loans, and consumer loans, and provides more specific detail regarding charge-offs and recoveries for each loan component and the composition of the loan portfolio at September 30, 2017 and September 30, 2016.

In early September, the State of Florida was preparing for the potential impact of Hurricane Irma. Ultimately the storm made landfall in the Florida Keys as a category 4 storm and a second landfall in Marco Island in southwest Florida. In the days following the storm, we conducted site visits and inquiries with commercial customers throughout our markets to help assess potential recovery needs. We had direct conversations with commercial customers covering 69% of the commercial portfolio, and expect any credit-related impacts to be nominal.

Acquisition Accounting and Purchased Loans – Critical Accounting Policies and Estimates

The Company accounts for its acquisitions under ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. All identifiable assets acquired, including loans, are recorded at fair value. No allowance for loan losses related to the acquired loans is recorded on the acquisition date as the fair value of the loans acquired incorporates assumptions regarding credit risk. All loans acquired are recorded at fair value in accordance with the fair value methodology prescribed in ASC Topic 820. The fair value estimates associated with the loans include estimates related to expected prepayments and the amount and timing of expected principal, interest and other cash flows.

Over the life of the purchased credit impaired loans acquired, the Company continues to estimate cash flows expected to be collected. The Company evaluates at each balance sheet date whether the present value of the acquired loans using the effective interest rates has decreased and if so, recognizes a provision for loan loss in its consolidated statement of income. For any increases in cash flows expected to be collected, the Company adjusts the amount of accretable yield recognized on a prospective basis over the loan’s remaining life.

Intangible Assets and Impairment Testing – Critical Accounting Policies and Estimates

Intangible assets consist of goodwill and core deposit intangibles. Goodwill represents the excess purchase price over the fair value of net assets acquired in business acquisitions. The core deposit intangible represents the excess intangible value of acquired deposit customer relationships as determined by valuation specialists. The core deposit intangibles from the BANKshares, Grand, Floridian, BMO, and GulfShore acquisitions are being amortized over 74 months, 94 months, 69 months, 87 months, and 98 months, respectively, on a straight-line basis, and are evaluated for indications of potential impairment at least annually. Goodwill is not amortized but rather is evaluated for impairment on at least an annual basis. We performed an annual impairment test of goodwill and core deposit intangibles as required by FASB ASC 350, Intangibles—Goodwill and Other, in the fourth quarter of 2016. Seacoast employed an independent third party with extensive experience in conducting and documenting impairment tests of this nature, and concluded that no impairment occurred.

Fair value estimates for acquired assets and assumed liabilities are based on the information available, and are subject to change for up to one year after the closing date of the acquisition as additional information relative to closing date fair values becomes available.

Other Fair Value Measurements – Critical Accounting Policies and Estimates

“As Is” values are used to measure fair market value on impaired loans, OREO and repossessed assets. All impaired loans, OREO and repossessed assets are reviewed quarterly to determine if fair value adjustments are necessary based on known changes in the market and/or the project assumptions.  When necessary, the “As Is” appraised value may be adjusted based on more recent appraisal assumptions received by the Company on other similar properties, the tax assessed market value, comparative sales and/or an internal valuation. Collateral dependent impaired loans are loans that are solely dependent on the liquidation or operation of the collateral for repayment.  If an updated assessment is deemed necessary and an internal valuation cannot be made, an external “As Is” appraisal will be requested. Upon receipt of the “As Is” appraisal a charge-off is recognized for the difference between the loan amount and its current fair market value.

At September 30, 2017, outstanding securities designated as available for sale totaled $996.8 million. The fair value of the available for sale portfolio at September 30, 2017 was less than historical amortized cost, producing net unrealized losses of $0.4 million that have been included in other comprehensive income (loss) as a component of shareholders’ equity (net of taxes). The Company made no change to the valuation techniques used to determine the fair values of securities during 2017 and 2016. The fair value of each security available for sale was obtained from independent pricing sources utilized by many financial institutions or from dealer quotes. The fair value of many state and municipal securities are not readily available through market sources, so fair value estimates are based on quoted market price or prices of similar instruments. Generally, the Company obtains one price for each security. However, actual values can only be determined in an arms-length transaction between a willing buyer and seller that can, and often do, vary from these reported values. Furthermore, significant changes in recorded values due to changes in actual and perceived economic conditions can occur rapidly, producing greater unrealized losses or gains in the available for sale portfolio.

71

The credit quality of the Company’s securities holdings are primarily investment grade. As of September 30, 2017, the Company’s available for sale investment securities, except for approximately $60.2 million of securities issued by states and their political subdivisions, generally are traded in liquid markets. U.S. Treasury and U.S. Government agency obligations totaled $544.5 million, or 55 percent of the total available for sale portfolio. The portfolio also includes $85.0 million in private label securities, most secured by residential real estate collateral originated in 2005 or prior years with low loan to values, and current FICO scores above 700. Generally these securities have credit support exceeding 5%. The collateral underlying these mortgage investments are primarily 30- and 15-year fixed rate, 5/1 and 10/1 adjustable rate mortgage loans. Historically, the mortgage loans serving as collateral for those investments have had minimal foreclosures and losses. The Company also has invested $208.1 million in uncapped 3-month Libor floating rate collateralized loan obligations. Collateralized loan obligations are special purpose vehicles that purchase loans as assets that provide a steady stream of income and possible capital appreciation. The collateral for the securities is first lien senior secured corporate debt. The Company has purchased senior tranches rated credit A or higher and performed stress tests, which indicated that the senior subordination levels are sufficient and no principal loss is forecast, verifying the independent rating. In addition, the Company has acquired several corporate bonds and private commercial mortgage backed securities totaling $99.0 million at September 30, 2017. At March 11, 2016 and July 17, 2015, Floridian and Grand securities of $67.0 million and $46.4 million, respectively, were acquired and added to the available for sale portfolio at their fair value. At April 7, 2017, nominal securities were acquired from the GulfShore acquisition.

During 2014, management identified $158.8 million of investment securities available for sale and transferred them to held to maturity. The unrealized holding losses at the date of transfer totaled $3.0 million. For the securities that were transferred into the held to maturity category from the available for sale category, the unrealized holding losses at the date of the transfer will continue to be reported in other comprehensive income, and will be amortized over the remaining life of the security as an adjustment of yield in a manner consistent with the amortization of a discount. At September 30, 2017, the remaining unamortized amount of these losses was $1.5 million. The amortization of unrealized holding losses reported in equity will offset the effect on interest income of the amortization of the discount. Management believes the securities transferred are a core banking asset that they now intend to hold until maturity, and if interest rates were to increase before maturity, the fair values would be impacted more significantly and therefore are not consistent with the characteristics of an available for sale investment.

Seacoast Bank also holds 211,330 shares of Visa Class B stock, which following resolution of Visa’s litigation will be converted to Visa Class A shares (the conversion rate presently is 1.6483 shares of Class A stock for each share of Class B stock) for a total of 348,335 shares of Visa Class A stock. Our holdings are related to prior ownership in Visa’s network while Visa operated as a cooperative (11,330 shares), and by acquisition via auctions (200,000 shares) for $6.2 million conducted by the FDIC during the first quarter of 2017. Our ownership is recorded on our financial records at $6.2 million.

72

Other Than Temporary Impairment of Securities – Critical Accounting Policies and Estimates

Our investments are reviewed quarterly for other than temporary impairment (“OTTI”). The following primary factors are considered for securities identified for OTTI testing: percent decline in fair value, rating downgrades, subordination, duration, amortized loan-to-value, and the ability of the issuers to pay all amounts due in accordance with the contractual terms. Prices obtained from pricing services are usually not adjusted. Based on our internal review procedures and the fair values provided by the pricing services, we believe that the fair values provided by the pricing services are consistent with the principles of ASC 820, Fair Value Measurement. However, on occasion pricing provided by the pricing services may not be consistent with other observed prices in the market for similar securities. Using observable market factors, including interest rate and yield curves, volatilities, prepayment speeds, loss severities and default rates, the Company may at times validate the observed prices using a discounted cash flow model and using the observed prices for similar securities to determine the fair value of its securities.

Changes in the fair values, as a result of deteriorating economic conditions and credit spread changes, should only be temporary. Further, management believes that the Company’s other sources of liquidity, as well as the cash flow from principal and interest payments from its securities portfolio, reduces the risk that losses would be realized as a result of a need to sell securities to obtain liquidity.

Realization of Deferred Tax Assets – Critical Accounting Policies and Estimates

At September 30, 2017, the Company had net deferred tax assets (“DTA”) of $44.0 million. Although realization is not assured, management believes that realization of the carrying value of the DTA is more likely than not, based upon expectations as to future taxable income and tax planning strategies, as defined by ASC 740 Income Taxes. In comparison, at September 30, 2016 the Company had a net DTA of $58.8 million.

Factors that support this conclusion:

· Income before tax (“IBT”) has steadily increased as a result of organic growth, and we believe that the 2017 GulfShore, NorthStar and BMO acquisitions, and 2016 Floridian and BMO acquisitions will further assist in achieving management’s forecast of future earnings which recovers the net operating loss carry-forwards well before expiration;

· Credit costs and overall credit risk has been stable which decreases their impact on future taxable earnings;

· Growth rates for loans are at levels adequately supported by loan officers and support staff;

· We believe new loan production credit quality and concentrations are well managed; and

· Current economic growth forecasts for Florida and the Company’s markets are supportive.

73

Contingent Liabilities – Critical Accounting Policies and Estimates

The Company is subject to contingent liabilities, including judicial, regulatory and arbitration proceedings, and tax and other claims arising from the conduct of our business activities. These proceedings include actions brought against the Company and/or our subsidiaries with respect to transactions in which the Company and/or our subsidiaries acted as a lender, a financial advisor, a broker or acted in a related activity. Accruals are established for legal and other claims when it becomes probable that the Company will incur an expense and the amount can be reasonably estimated. Company management, together with attorneys, consultants and other professionals, assesses the probability and estimated amounts involved in a contingency. Throughout the life of a contingency, the Company or our advisors may learn of additional information that can affect our assessments about probability or about the estimates of amounts involved. Changes in these assessments can lead to changes in recorded reserves. In addition, the actual costs of resolving these claims may be substantially higher or lower than the amounts reserved for the claims. At September 30, 2017, the Company had no significant accruals for contingent liabilities and had no known pending matters that could potentially be significant.

Interest Rate Sensitivity

Fluctuations in interest rates may result in changes in the fair value of the Company’s financial instruments, cash flows and net interest income. This risk is managed using simulation modeling to calculate the most likely interest rate risk utilizing estimated loan and deposit growth. The objective is to optimize the Company’s financial position, liquidity, and net interest income while limiting their volatility.

Senior management regularly reviews the overall interest rate risk position and evaluates strategies to manage the risk. The Company’s third quarter 2017 Asset and Liability Management Committee (“ALCO”) model simulation indicates net interest income would increase 7.1% if interest rates increased 200 basis points up over the next 12 months and 3.7% if interest rates increased 100 basis points, and improve 12.5% and 6.5% respectively, on a 13 to 24 month basis. This compares with the Company’s third quarter 2016 model simulation, which indicated net interest income would increase 7.8% if interest rates were increased 200 basis points over the next 12 months and 4.1% if interest rates were increased 100 basis points. Recent regulatory guidance has placed more emphasis on rate shocks, adding a 13-24 month horizon.

The Company had a positive gap position based on contractual and prepayment assumptions for the next 12 months, with a positive cumulative interest rate sensitivity gap as a percentage of total earning assets of 16.4% at September 30, 2017. This result includes assumptions for core deposit re-pricing validated for the Company by an independent third party consulting group.

The computations of interest rate risk do not necessarily include certain actions management may undertake to manage this risk in response to changes in interest rates. Derivative financial instruments, such as interest rate swaps, options, caps, floors, futures and forward contracts may be utilized as components of the Company’s risk management profile.

Effects of Inflation and Changing Prices

The condensed consolidated financial statements and related financial data presented herein have been prepared in accordance with U.S. GAAP, which require the measurement of financial position and operating results in terms of historical dollars, without considering changes in the relative purchasing power of money, over time, due to inflation.

74

Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates have a more significant impact on a financial institution’s performance than the general level of inflation. However, inflation affects financial institutions by increasing their cost of goods and services purchased, as well as the cost of salaries and benefits, occupancy expense, and similar items. Inflation and related increases in interest rates generally decrease the market value of investments and loans held and may adversely affect liquidity, earnings, and shareholders’ equity. Mortgage originations and re-financings tend to slow as interest rates increase, and higher interest rates likely will reduce the Company’s earnings from such activities and the income from the sale of residential mortgage loans in the secondary market.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

See Management’s discussion and analysis “Interest Rate Sensitivity”.

Market risk refers to potential losses arising from changes in interest rates, and other relevant market rates or prices.

Interest rate risk, defined as the exposure of net interest income and Economic Value of Equity, or “EVE,” to adverse movements in interest rates, is the Company’s primary market risk, and mainly arises from the structure of the balance sheet (non-trading activities). The Company is also exposed to market risk in its investing activities. The Company’s Asset/Liability Committee, or “ALCO,” meets regularly and is responsible for reviewing the interest rate sensitivity position of the Company and establishing policies to monitor and limit exposure to interest rate risk. The policies established by the ALCO are reviewed and approved by the Company’s Board of Directors. The primary goal of interest rate risk management is to control exposure to interest rate risk, within policy limits approved by the Board. These limits reflect the Company’s tolerance for interest rate risk over short-term and long-term horizons.

The Company also performs valuation analyses, which are used for evaluating levels of risk present in the balance sheet that might not be taken into account in the net interest income simulation analyses. Whereas net interest income simulation highlights exposures over a relatively short time horizon, valuation analysis incorporates all cash flows over the estimated remaining life of all balance sheet positions. The valuation of the balance sheet, at a point in time, is defined as the discounted present value of asset cash flows minus the discounted value of liability cash flows, the net result of which is the EVE. The sensitivity of EVE to changes in the level of interest rates is a measure of the longer-term re-pricing risks and options risks embedded in the balance sheet. In contrast to the net interest income simulation, which assumes interest rates will change over a period of time, EVE uses instantaneous changes in rates.

75

EVE values only the current balance sheet, and does not incorporate the growth assumptions that are used in the net interest income simulation model. As with the net interest income simulation model, assumptions about the timing and variability of balance sheet cash flows are critical in the EVE analysis. Particularly important are the assumptions driving prepayments and the expected changes in balances and pricing of the indeterminate life deposit portfolios. Core deposits are a more significant funding source for the Company, making the lives attached to core deposits more important to the accuracy of our modeling of EVE. The Company periodically reassesses its assumptions regarding the indeterminate lives of core deposits utilizing an independent third party resource to assist. With lower interest rates over a prolonged period, the average lives of core deposits have trended higher and favorably impacted our model estimates of EVE for higher rates. Based on our third quarter 2017 modeling, an instantaneous 100 basis point increase in rates is estimated to increase the EVE 12.0% versus the EVE in a stable rate environment, while a 200 basis point increase in rates is estimated to increase the EVE 19.3%.

While an instantaneous and severe shift in interest rates is used in this analysis to provide an estimate of exposure under an extremely adverse scenario, a gradual shift in interest rates would have a much more modest impact. Since EVE measures the discounted present value of cash flows over the estimated lives of instruments, the change in EVE does not directly correlate to the degree that earnings would be impacted over a shorter time horizon, i.e., the next fiscal year. Further, EVE does not take into account factors such as future balance sheet growth, changes in product mix, change in yield curve relationships, and changing product spreads that could mitigate the adverse impact of changes in interest rates.

76

Item 4. CONTROLS AND PROCEDURES

The Company’s management, with the participation of its chief executive officer and chief financial officer has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act) as of September 30, 2017 and concluded that those disclosure controls and procedures are effective. There have been no changes to the Company’s internal control over financial reporting that occurred since the beginning of the Company’s third quarter of 2017 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

While the Company believes that its existing disclosure controls and procedures have been effective to accomplish these objectives, the Company intends to continue to examine, refine and formalize its disclosure controls and procedures and to monitor ongoing developments in this area.

77

Part II OTHER INFORMATION

Item 1. Legal Proceedings

The Company and its subsidiaries are subject, in the ordinary course, to litigation incident to the business in which they are engaged. Management presently believes that none of the legal proceedings to which the Company or any of its subsidiaries is a party or of which any of their property is the subject are likely to have a material adverse effect on the Company’s consolidated financial position, or operating results or cash flows, although no assurance can be given with respect to the ultimate outcome of any such claim or litigation.

Item 1A. Risk Factors

In addition to the other information set forth in this report, you should consider the factors discussed in “Part I, Item 1A. Risk Factors” in our report on Form 10-K for the year ended December 31, 2016, which could materially affect our business, financial condition and prospective results.

Operating results for the nine-month period ended September 30 2017, are not necessarily indicative of the results that may be expected for the year ending December 31, 2017 or any other period. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2016.

Use of Estimates

The preparation of these condensed consolidated financial statements required the use of certain estimates by management in determining the Company’s assets, liabilities, revenues and expenses. Actual results could differ from those estimates.

Specific areas, among others, requiring the application of management’s estimates include determination of the allowance for loan losses, the valuation of investment securities available for sale, fair value of impaired loans, contingent liabilities, fair value of other real estate owned, and the valuation of deferred tax assets. Actual results could differ from those estimates.

RECENTLY ISSUED ACCOUNTING STANDARDS, Not adopted as of September 30, 2017

Accounting Changes and Error Corrections [Abstract]

RECENTLY ISSUED ACCOUNTING STANDARDS

NOTE B — RECENTLY ISSUED ACCOUNTING STANDARDS, Not adopted as of September 30, 2017

The following provides a brief description of accounting standards that have been issued but are not yet adopted that could affect the Company's financial statements:

In May 2017, the Financial Account Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09, clarifying when changes to the terms of share-based awards, such as value, vesting conditions or classification of the awards, should be accounted for as modifications. All the disclosures about modifications that are currently required would need to be made, along with disclosure of any change (or no change) in compensation expense. This guidance is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted. Adoption of this standard is being evaluated as to its effect on the Company’s operating results and financial condition.

In March 2017, the FASB issued ASU 2017-08, requiring entities to amortize premiums on certain purchased callable debt securities to their earliest call date. The accounting for purchased callable debt securities held at a discount did not change. Amortizing the premium to the earliest call date generally aligns interest income recognition with the economics of instruments. This guidance requires a modified retrospective transition under which a cumulative adjustment will be made to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This guidance is effective for fiscal years beginning after December 15, 2018. Adoption of this standard is being evaluated as to its effect on the Company’s operating results or financial condition.

In January 2017, the FASB issued ASU 2017-04, eliminating Step 2 from the goodwill impairment test. Under the amendments to the guidance, an entity should perform its 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. The loss recognized, however, 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.  The guidance is effective for annual periods or any interim goodwill impairment tests beginning after December 15, 2019 using a prospective transition method. Early adoption is permitted. Adoption of this standard is being evaluated as to its effect on the Company’s operating results or financial condition.

In August and November 2016, the FASB issued final guidance via ASU 2016-15 and ASU 2016-18, which address classification of certain cash receipts and cash payments, including changes in restricted cash, in the statement of cash flows. The guidance may change how an entity classifies certain cash receipts and cash payments on its statement of cash flows, the purpose being to reduce diversity in practice. The Company is evaluating the impact of ASU 2016-15 and 2016-18 on the Company’s statement of cash flows which will generally be applied retrospectively for fiscal years beginning after December 15, 2017.

In June 2016, the FASB issued ASU 2016-13 for “Measurement of Credit Losses on Financial Instruments” to replace the incurred loss impairment methodology with a current expected credit loss methodology for financial instruments measured at amortized cost and other commitments to extend credit. Expected credit losses reflect losses over the remaining contractual life of an asset, considering the effect of voluntary prepayments and considering available information about the collectability of cash flows, including information about past events, current conditions, and supportable forecasts. The resultant allowance for credit losses reflects the portion of the amortized cost basis that the entity does not expect to collect. Additional quantitative and qualitative disclosures are required upon adoption. The Company has established a transition oversight committee that is responsible for assessing expected loss estimation models, data requirements, and changes in processes that will be necessary to meet the requirements of this new accounting guidance. Adoption is required January 1, 2020, with early adoption permitted on January 1, 2019.

In March 2016, under ASU 2016-04, “Liabilities – Extinguishments of Liabilities, Breakage for Certain Prepaid Stored-Value Products” the FASB intends for entities to recognize liabilities for the sale of prepaid stored value products redeemable for goods, services, or cash. This guidance aligns recognition of breakage for these liabilities in a way consistent with how gift card breakage will be recognized. The Company does not expect adoption of this standard to affect the Company’s operating results or financial condition. Effective date for implementation of the guidance is for annual periods after December 15, 2018.

In February 2016, the FASB amended existing guidance related to the recognition of lease assets and lease liabilities on the balance sheet and disclosures of key information about leasing arrangements, under ASU 2016-02. The guidance requires all parties to classify leases to determine how to recognize lease-related revenue and expense. The amendment requires lessees to put most leases on their balance sheet and record expenses to the income statement. Changes in the guidance eliminate real estate centric provisions for sale-leaseback transactions, including initial direct costs and lease execution costs for all entities. For lessors, the new FASB standard modifies classification criteria and accounting for sales type and direct financing leases. The Company is currently evaluating the impact of adopting the new guidance on its consolidated financial statements. The amended accounting guidance is applicable to periods after December 15, 2018 and interim periods within that year.

In January 2016, the FASB issued ASU 2016-01 for “Recognition and Measurement of Financial Assets and Liabilities.” The ASU addresses certain aspects of recognition, measurement, presentation, and disclosure of financial instruments. The update: a) requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value and recognized in net income, b) simplifies impairment assessments of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, and if impaired requires measurement of the investment at fair value, c) eliminates the requirement to disclose the methods and significant assumptions used to estimate the fair value, d) requires entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, e) requires an entity to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments, f) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (that is, securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements, and g) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities in combination with the entity’s other deferred tax assets. The Company is evaluating the use of the measurement alternative available for equity securities without a readily determinable fair value, and the related impact to accounting policies, presentation, and disclosures. The ASU is effective for fiscal years beginning after December 15, 2017, and must be adopted on a modified retrospective basis, including interim periods within those fiscal years.

In May 2014, the FASB issued ASU 2014-09, “Revenue Recognition – Revenue from Contracts with Customers.” The ASU is a converged standard between the FASB and the IASB that provides a single comprehensive revenue recognition model for all contracts with customers across transactions and industries. The primary objective of the ASU is revenue recognition that represents the transfer of control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue associated with loans and securities is not in the scope of the new guidance, and based on the Company’s evaluation to date we do not expect the adoption to have a significant impact on the Company’s operating results or financial condition. The Company continues to evaluate the changes in disclosures required by the new guidance. The Company plans to adopt the new guidance on January 1, 2018.

Proceeds from sales of securities during the three month period ended September 30, 2017 were $3.7 million, with gross gains of $15,000 and gross losses of $62,000. Proceeds from sales of securities during the nine month period ended September 30, 2017 were $7.5 million, with gross gains of $36,000 and gross losses of $62,000. Proceeds from sales of securities during the three month period ended September 30, 2016 were $26.8 million, with gross gains of $301,000 and gross losses of $76,000. Proceeds from sales of securities during the nine month period ended September 30, 2016 were $39.0 million, with gross gains of $448,000 and gross losses of $87,000.

In 2014, approximately $158.8 million of investment securities available for sale were transferred into held to maturity. The unrealized holding losses at the date of transfer totaled $3.1 million. The unrealized holding losses at the date of the transfer are amortized over the remaining life of these securities as an adjustment of yield in a manner consistent with the amortization of a discount. The amortization of unrealized holding losses reported in other comprehensive income will offset the effect on interest income of the amortization of the discount. At September 30, 2017, the remaining unrealized holding losses from this transfer totaled $1.5 million.

Securities at September 30, 2017 with a fair value of $178.3 million were pledged as collateral for United States Treasury deposits, other public deposits and trust deposits. Securities with a fair value of $142.2 million were pledged as collateral for repurchase agreements at September 30, 2017.

The amortized cost and fair value of securities available for sale and held to maturity at September 30, 2017, by contractual maturity, are shown below. Expected maturities will differ from contractual maturities because prepayments of the underlying collateral for these securities may occur, due to the right to call or repay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

The two tables above include securities held to maturity that were transferred from available for sale into held to maturity during 2014. Those securities had unrealized losses of $3.1 million at the date of transfer, and at September 30, 2017, the unamortized balance was $1.5 million. The fair value of those securities in an unrealized loss position for less than twelve months at September 30, 2017 and December 31, 2016 was $6.6 million and $22.8 million, respectively. The additional unrealized losses on those securities in an unrealized loss position for less than twelve months at September 30, 2017 and December 31, 2016 was $0.1 million and $0.4 million, respectively. The fair value of those securities in an unrealized loss position for more than twelve months at September 30, 2017 and December 31, 2016 was $13.1 million and none, respectively. The additional unrealized losses on those securities in an unrealized loss position for more than twelve months at September 30, 2017 and December 31, 2016 was $0.2 million and none, respectively.

At September 30, 2017, unrealized losses on mortgage backed securities, collateralized mortgage obligations and commercial mortgage backed securities of U.S. government sponsored entities having a fair value of $542.0 million totaled $8.8 million, which was attributable to a combination of factors, including relative changes in interest rates since the time of purchase. The contractual cash flows for these securities are guaranteed by U.S. government agencies and U.S. government-sponsored enterprises. Based on our assessment of these factors, management believes that the unrealized losses on these debt security holdings are a function of changes in investment spreads and interest rate movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.

At September 30, 2017, private label securities secured by seasoned residential collateral with a fair value of $22.0 million had approximately $0.4 million in unrealized losses. This was attributable to a combination of factors, including relative changes in interest rates since the time of purchase. The collateral underlying these mortgage investments are 30- and 15-year fixed rate loans and 10/1 adjustable rate mortgage loans with low loan to values, subordination and historically have had minimal foreclosures and losses. Based on its assessment of these factors, management believes that the unrealized losses on these debt security holdings are a function of changes in investment spreads and interest rate movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.

At September 30, 2017, remaining securities categories had unrealized losses of $0.6 million and a fair value of $60.1 million. Management believes that unrealized losses on these remaining debt security holdings are a function of changes in investment spreads and interest movements and not changes in credit quality. Management expects to recover the entire amortized cost basis of these securities.

As of September 30, 2017, management does not intend to sell securities that are in unrealized loss positions and it is not more likely than not that the Company will be required to sell these securities before recovery of the amortized cost basis. Therefore, management does not consider any investment to be other-than-temporarily impaired at September 30, 2017.

Included in other assets is $38.6 million of Federal Home Loan Bank and Federal Reserve Bank stock stated at par value. At September 30, 2017, the Company had not identified events or changes in circumstances which may have a significant adverse effect on the ability to redeem these holdings.

The Company also holds 211,330 shares of Visa Class B stock which, following resolution of Visa litigation, will be converted to Visa Class A shares (the conversion rate is 1.6483 shares of Class A stock for each share of Class B stock) for a total of 348,335 shares of Visa Class A stock. Our holdings are related to prior ownership in Visa’s network while Visa operated as a cooperative (11,330 shares), and by acquisition via auctions (200,000 shares) for $6.2 million conducted by the FDIC during the first quarter of 2017. These holdings are reported in other assets in the Consolidated Balance Sheets at the Company’s cost of $6.2 million.

Purchased Loans - PCI loans are accounted for pursuant to ASC Topic 310-30. The excess of cash flows expected to be collected over the estimated fair value is referred to as the accretable yield and is recognized in interest income over the remaining life of the loan in situations where there is a reasonable expectation about the timing and amount of cash flows expected to be collected. The difference between the contractually required payments and the cash flows expected to be collected, considering the impact of prepayments, is referred to as the nonaccretable difference. We have applied ASC Topic 310-20 accounting treatment to PULs.

The table below summarizes the changes in accretable yield for PCI loans during the three and nine month periods ended September 30, 2017 and 2016, respectively:

The Company utilizes an internal asset classification system as a means of reporting problem and potential problem loans.  Under the Company’s risk rating system, the Company classifies problem and potential problem loans as “Special Mention,” “Substandard,” and “Doubtful” and these loans are monitored on an ongoing basis.  Loans that do not currently expose the Company to sufficient risk to warrant classification in the Substandard or Doubtful categories, but possess weaknesses that deserve management’s close attention are deemed to be Special Mention. Substandard loans include those characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.  Loans classified as Substandard may require a specific allowance. Loans classified as Doubtful have all the weaknesses inherent in those classified Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable.  The principal on loans classified as Doubtful is generally charged off.  Risk ratings are updated any time the situation warrants.

Loans that are not problem or potential problem loans are considered to be pass-rated loans and risk grades are recalculated at least annually by the loan relationship manager.  The following tables present the risk category of loans by class of loans based on the most recent analysis performed as of September 30, 2017 and December 31, 2016:

IMPAIRED LOANS AND ALLOWANCE FOR LOAN LOSSES

9 Months Ended

Sep. 30, 2017

Loans and Leases Receivable Disclosure [Abstract]

Impaired Loans and Allowance for Loan Losses

NOTE F — IMPAIRED LOANS AND ALLOWANCE FOR LOAN LOSSES

The Company’s Troubled Debt Restructuring (“TDR”) concessions granted generally do not include forgiveness of principal balances, but may include interest rate reductions, an extension of the amortization period and/or converting the loan to interest only for a limited period of time. Loan modifications are not reported in calendar years after modification if the loans were modified at an interest rate equal to the yields of new loan originations with comparable risk and the loans are performing based on the terms of the restructuring agreements. Most loans prior to modification were classified as an impaired loan and the allowance for loan losses is determined in accordance with Company policy.

The following table presents loans that were modified during the nine months ended September 30, 2017:

			Pre-		Post-
			Modification		Modification
	Number		Outstanding		Outstanding		Valuation

During the nine months ended September 30, 2017 and 2016, there were no payment defaults on loans that had been modified in a TDR within the previous twelve months. The Company considers a loan to have defaulted when it becomes 90 days or more delinquent under the modified terms, has been transferred to nonaccrual status, or has been transferred to other real estate owned. A defaulted TDR is generally placed on nonaccrual and a specific allowance for loan loss is assigned in accordance with the Company’s policy.

As of September 30, 2017 and December 31, 2016, the Company’s recorded investment in impaired loans (excluding PCI loans), the unpaid principal balance, and the related valuation allowance were as follows:

Impaired loans also include loans that have been modified in TDRs where concessions to borrowers who experienced financial difficulties have been granted. At September 30, 2017 and at December 31, 2016, accruing TDRs totaled $16.2 million and $17.7 million, respectively.

The impaired loans are measured for impairment based on the value of underlying collateral or the present value of expected future cash flows discounted at the loan’s effective rate. The valuation allowance is included in the allowance for loan losses.

Interest payments received on impaired loans are recorded as interest income unless collection of the remaining recorded investment is doubtful at which time payments received are recorded as reductions to principal.

For impaired loans whose impairment is measured based on the present value of expected future cash flows, a total of $169,000 and $282,000 for the three and nine months ended September 30, 2017, respectively, and $83,000 and $176,000 for the three and nine months ended September 30, 2016, respectively, was included in interest income, and this represents the change in present value attributable to the passage of time, and reduces the associated allowance for loan losses.

Nonaccrual loans and accruing loans past due 90 days or more (excluding purchased loans) totaled $10.9 million and $0, respectively, at September 30, 2017, and $11.0 million and $0, respectively, at December 31, 2016. Purchased nonaccrual and accruing loans past due 90 days or more were $3.5 million and $0 million, respectively, at September 30, 2017, and $7.0 million and $0, respectively, at December 31, 2016.

Activity in the allowance for loan losses (excluding PCI loans) for the three month and nine month periods ended September 30, 2017 and 2016 is summarized as follows:

(1) See Note D for further detail of fair value of individual investment categories.

(2) Recurring fair value basis determined using observable market data.

(3) See Note F. Nonrecurring fair value adjustments to loans identified as impaired reflect full or partial write-downs that are based on the loan’s observable market price or current appraised value of the collateral in accordance with ASC 310.

(4) Fair value is measured on a nonrecurring basis in accordance with ASC 360.

The fair value of impaired real estate loans which are collateral dependent is based on recent real estate appraisals less estimated costs of sale. For residential real estate impaired loans, appraised values or internal evaluation are based on the comparative sales approach. These impaired loans are considered level 2 in the fair value hierarchy. For commercial and commercial real estate impaired loans, evaluations may use either a single valuation approach or a combination of approaches, such as comparative sales, cost and/or income approach. A significant unobservable input in the income approach is the estimated capitalization rate for a given piece of collateral. At September 30, 2017, the capitalization rates utilized to determine fair value of the underlying collateral averaged approximately 7.7%. Adjustments to comparable sales may be made by an appraiser to reflect local market conditions or other economic factors and may result in changes in the fair value of an asset over time. As such, the fair value of these impaired loans is considered level 3 in the fair value hierarchy. Impaired loans measured at fair value totaled $4.2 million with a specific reserve of $1.4 million at September 30, 2017, compared to $4.1 million with a specific reserve of $0.4 million at December 31, 2016.

Fair value of available for sale securities is determined using valuation techniques for individual investments as described in Note D.

When appraisals are used to determine fair value and the appraisals are based on a market approach, the fair value of other real estate owned (“OREO”) is classified as a level 2 input. When the fair value of OREO is based on appraisals which require significant adjustments to market-based valuation inputs or apply an income approach based on unobservable cash flows, the fair value of OREO is classified as Level 3.

Transfers between levels of the fair value hierarchy are recognized on the actual date of the event or circumstances that caused the transfer, which generally coincides with the Company’s monthly and/or quarter-end valuation process.

During the nine months ended September 30, 2017 and 2016, there were no transfers between levels of the fair value hierarchy.

For loans classified as level 3, additions totaled $0.8 million for the first nine months of 2017, consisting of loans that became impaired during 2017. Reductions consisted primarily of principal payments and totaled $0.6 million.

Charge-offs recognized upon loan foreclosures are generally offset by general or specific allocations of the allowance for loan losses and generally do not, and did not during the reported periods, significantly impact the Company’s provision for loan losses.

For OREO classified as level 3 during the first nine months of 2017, foreclosed loans added $0.4 million and migrated branches taken out of service added $1.2 million. Reductions summed to $4.4 million and consisted almost entirely of sales of $4.2 million.

The carrying amount and fair value of the Company’s other significant financial instruments that are not measured at fair value on a recurring basis in the balance sheet as of September 30, 2017 and December 31, 2016 is as follows:

The short maturity of Seacoast’s assets and liabilities results in having a significant number of financial instruments whose fair value equals or closely approximates carrying value. Such financial instruments are reported in the following balance sheet captions: cash and due from banks, interest bearing deposits with other banks, federal funds purchased, and securities sold under agreement to repurchase, maturing within 30 days, and FHLB borrowings.

The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value at September 30, 2017 and December 31, 2016:

Securities: U.S. Treasury securities are reported at fair value utilizing Level 1 inputs. Other securities are reported at fair value utilizing Level 2 inputs. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other factors.

The Company reviews the prices supplied by independent pricing services, as well as their underlying pricing methodologies, for reasonableness and to ensure such prices are aligned with traditional pricing matrices. The fair value of collateralized loan obligations is determined from broker quotes. From time to time, the Company will validate, on a sample basis, prices supplied by the independent pricing service by comparison to prices obtained from other brokers and third-party sources or derived using internal models.

Loans: Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial or mortgage. Each loan category is further segmented into fixed and adjustable rate interest terms and by performing and nonperforming categories. The fair value of loans, except residential mortgages, is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risks inherent in the loan. For residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusting for prepayment assumptions using discount rates based on secondary market sources. The estimated fair value is not an exit price fair value under ASC 820 when this valuation technique is used.

Loans held for sale: Fair values are based upon estimated values received from independent third party purchasers. These loans are intended for sale and the Company believes that the fair value is the best indicator of the resolution of these loans. Interest income is recorded based on the contractual terms of the loan and in accordance with the Company’s policy on loans held for investment. None of the loans are 90 days or more past due or on nonaccrual as of September 30, 2017 and December 31, 2016, respectively. Loans held for sale were as follows at September 30, 2017 and December 31, 2016:

	September 30,		December 31,
(Dollars in thousands)	2017		2016
Aggregate fair value	$	29,447	$	15,332
Contractual balance		28,782		14,904
Gains		665		428

Deposit Liabilities: The fair value of demand deposits, savings accounts and money market deposits is the amount payable at the reporting date. The fair value of fixed maturity certificates of deposit is estimated using the rates currently offered for funding of similar remaining maturities.

NOTE L — BUSINESS COMBINATIONS

Acquisition of Floridian Financial Group, Inc.

On March 11, 2016, the Company completed its acquisition of Floridian. Simultaneously, upon completion of the merger, Floridian’s wholly owned subsidiary bank, Floridian Bank, was merged with and into Seacoast Bank. Floridian, headquartered in Lake Mary, Florida, operated 10 branches in Orlando and Daytona Beach, of which several were consolidated with Seacoast locations. This acquisition added approximately $417 million in total assets, $337 million in deposits, and $266 million in loans to Seacoast.

The Company acquired 100% of the outstanding common stock of Floridian. Under the terms of the definitive agreement, Floridian shareholders received, at their election, (i) the combination of $4.29 in cash and 0.5291 shares of Seacoast common stock, (ii) $12.25 in cash, or (iii) 0.8140 shares of Seacoast common stock, subject to a customary proration mechanism so that the aggregate consideration mix equaled 35% cash and 65% Seacoast shares (based on Seacoast’s closing price of $15.47 per share on March 11, 2016).

The following table represents the purchase price paid to Floridian shareholders in connection with the acquisition:

	March 11, 2016
Shares exchanged for cash	$	26,699,000
Number of Floridian Financial Group, Inc. common shares outstanding		6,222,119
Per share exchange ratio		0.5289

Multiplied by common stock price per share on March 11, 2016	$	15.47
Value of common stock issued		50,912,791
Total purchase price	$	77,611,791

The acquisition was accounted for under the acquisition method in accordance with ASC Topic 805, Business Combinations. The Company recognized goodwill of $32 million on this acquisition which is nondeductible for tax purposes as this acquisition was a nontaxable transaction. The goodwill was calculated based on the fair values of the assets acquired and liabilities assumed as of the acquisition date. Loans that were nonaccrual and all loan relationships identified as impaired as of the acquisition date were considered by management to be credit impaired and were accounted for pursuant to ASC Topic 310-30.

The table below presents information with respect to the fair value of acquired loans, as well as their unpaid principal balance (“Book Balance”) at acquisition date.

Purchased credit-impaired		6,186		2,643
Total acquired loans	$	280,022	$	266,137

For the loans acquired we first segregated all acquired loans with specifically identified credit deficiency factor(s). The factors we considered to identify loans as PCI loans were all acquired loans that were nonaccrual, 60 days or more past due, designated as TDRs, graded “special mention” or “substandard.” These loans were then evaluated to determine estimated fair values as of the acquisition date. As required by generally accepted accounting principles, we are accounting for these loans 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 March 11, 2016 for PCI loans. Contractually required principal and interest payments have been adjusted for estimated prepayments.

(In thousands)	March 11, 2016
Contractually required principal and interest	$	8,031
Non-accretable difference		(4,820)
Cash flows expected to be collected		3,211
Accretable yield		(568)
Total purchased credit-impaired loan acquired	$	2,643

Loans without specifically identified credit deficiency factors are referred to as Purchased Unimpaired Loans (“PULs”) for disclosure purposes. These loans were then evaluated to determine estimated fair values as of the acquisition date. Although no specific credit deficiencies were identifiable, we believe there is an element of risk as to whether all contractual cash flows will be eventually received. Factors that were considered included the economic environment both nationally and locally as well as the real estate market particularly in Florida. We have applied ASC Topic 310-20 accounting treatment to the PULs.

The Company believes 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. 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.

The acquisition of Floridian constitutes a business combination. Accordingly, the assets acquired and liabilities assumed are presented at their fair values. The determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change, and in some instances rely on use of third party experts.

Acquisition of BMO Harris Central Florida Offices, Deposits and Loans

On June 3, 2016, Seacoast Bank assumed approximately $314 million in deposits related to business and consumer banking customers at a deposit premium of 3.0% of the deposit balances, $63 million in business loans at a loan premium of 0.5%, and fourteen branches of BMO, located in the Orlando Metropolitan Statistical Area (“MSA”).

The acquisition is accounted for under the acquisition method in accordance with ASC Topic 805, Business Combinations. Determining fair values of assets and liabilities, especially the loan portfolio and bank premises and leases related to the fourteen branches acquired, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.

At June 3, 2016, no loans acquired from BMO were specifically identified with a credit deficiency factor(s). The factors we consider to identify loans as PCI loans are acquired loans that were nonaccrual, 60 days or more past due, designated as TDR, graded “special mention” or “substandard.” PULs were evaluated to determine estimated fair values as of the acquisition date. Although no specific credit deficiencies were identifiable, we believe there is an element of risk as to whether all contractual cash flows will be eventually received. Factors that were considered included the economic environment both nationally and locally as well as the real estate market particularly in Florida. We have applied ASC Topic 310-20 accounting treatment to the PULs.

The Company believes 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. In determining the valuation amount, a third party analyzed the deposits based on factors such as type of deposit, deposit retention, interest rates and age of deposit relationships.

The Company recognized intangibles (including goodwill) of approximately $13 million for this acquisition that are deductible for tax purposes over a 15-year period. The acquisition of BMO’s Orlando banking operations by Seacoast Bank constitutes a business combination. Accordingly, the assets acquired and liabilities assumed are presented at their fair values. The determination of fair value requires management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change, and in some instances rely on use of third party experts.

Acquisition of GulfShore Bancshares, Inc.

On April 7, 2017, the Company completed its acquisition of GulfShore. Simultaneously, upon completion of the merger, GulfShore’s wholly owned subsidiary bank, GulfShore Bank, was merged with and into Seacoast Bank. GulfShore, headquartered in Tampa, Florida, operated 3 branches in Tampa and St. Petersburg, of which all have been retained as Seacoast locations.

The Company acquired 100% of the outstanding common stock of GulfShore. Under the terms of the definitive agreement, GulfShore shareholders received, for each share of Gulfshore common stock, the combination of $1.47 in cash and 0.4807 shares of Seacoast common stock (based on Seacoast’s closing price of $23.94 per share on April 7, 2017).

Multiplied by common stock price per share on April 7, 2017	$	23.94
Value of common stock issued		62,883,030
Total purchase price	$	70,917,029

Merger related charges summed to $4.3 million for the second quarter of 2017, primarily impacting salaries and wages, outsourced data processing costs, and legal and professional fees. All of these costs were expensed in the second quarter of 2017.

The acquisition was accounted for under the acquisition method in accordance with ASC Topic 805, Business Combinations. The Company recognized goodwill of $37 million on this acquisition which is nondeductible for tax purposes as this acquisition was a nontaxable transaction. The goodwill was calculated based on the fair values of the assets acquired and liabilities assumed as of the acquisition date. The fair values initially assigned to assets acquired and liabilities assumed are preliminary and could change for up to one year after the closing date of the acquisition as new information and circumstances relative to closing date fair values are known. Determining fair values of assets and liabilities, especially the loan portfolio and foreclosed real estate, is a complicated process involving significant judgment regarding methods and assumptions used to calculate estimated fair values.

No loans acquired were specifically identified with credit deficiency factor(s), pursuant to ASC Topic 310-30. The factors we considered to identify loans as PCI loans were all acquired loans that were nonaccrual, 60 days or more past due, designated as TDR, graded “special mention” or “substandard.”

Loans without specifically identified credit deficiency factors are referred to as PULs for disclosure purposes. These loans were then evaluated to determine estimated fair values as of the acquisition date. Although no specific credit deficiencies were identifiable, we believe there is an element of risk as to whether all contractual cash flows will be eventually received. Factors that were considered included the economic environment both nationally and locally as well as the real estate market particularly in Florida. We have applied ASC Topic 310-20 accounting treatment to the PULs.

The Company believes 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. 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.

The determination of fair value required management to make estimates about discount rates, future expected cash flows, market conditions and other future events that are highly subjective in nature and subject to change, and in some instances rely on use of third party experts. These fair value estimates are considered preliminary and are subject to change for up to one year after the closing date of the acquisition as additional information becomes available. For GulfShore, fair values as presented for securities, loans, fixed assets, other real estate owned, and certain other assets and liabilities are necessarily considered preliminary.

Operating results of the Company for the three months ended September 30, 2017 include the operation of the acquired assets and assumed liabilities since the date of acquisition of April 7, 2017. Pro-forma data for the three months ended September 30, 2016 and nine months ended September 30, 2017 and 2016 listed in the table below present pro-forma information as if the acquisition occurred at the beginning of 2016.

Acquisition of NorthStar Bank

On October 20, 2017, the Company completed its acquisition of NorthStar Banking Corporation (“NSBC”). Simultaneously, upon completion of the merger, NSBC’s wholly owned subsidiary bank, NorthStar Bank, was merged with and into Seacoast Bank. NorthStar, headquartered in Tampa, Florida, operated three branches in Tampa, of which all have been retained as Seacoast locations.

The Company acquired 100% of the outstanding common stock of NSBC. Under the terms of the definitive agreement, NSBC shareholders received, for each share of NSBC common stock, the combination of $2.40 in cash and 0.5605 shares of Seacoast common stock.

On November 3, 2017, the Company completed its acquisition of Palm Beach Community Bank (“PBCB”), and PBCB was merged with and into Seacoast Bank. PBCB, headquartered in West Palm Beach, Florida, operated four branches in West Palm Beach, of which all have been retained as Seacoast locations.

The Company acquired 100% of the outstanding common stock of PBCB. Under the terms of the definitive agreement, PBCB shareholders received, for each share of PBCB stock, the combination of $6.26 in cash and 0.9240 shares of Seacoast common stock.

The acquisitions of NorthStar and PBCB will be accounted for under the acquisition method of accounting in accordance with ASC Topic 805, Business Combinations. The Company’s assessment of the fair value of assets acquired and liabilities assumed as of the acquisition date is incomplete at the time of this filing; therefore, certain disclosures have been omitted. The Company expects to recognize goodwill in each of these transactions, which is expected to be nondeductible for tax purposes.

Use of Estimates

Use of Estimates

The preparation of these condensed consolidated financial statements required the use of certain estimates by management in determining the Company’s assets, liabilities, revenues and expenses. Actual results could differ from those estimates.

Specific areas, among others, requiring the application of management’s estimates include determination of the allowance for loan losses, the valuation of investment securities available for sale, fair value of impaired loans, contingent liabilities, fair value of other real estate owned, and the valuation of deferred tax assets. Actual results could differ from those estimates.
